Example Of Differentiation & Positioning

Figure 1. 1 is a positioning map showing our target customers' percetions of our brand versus competing products on important buying dimensions, which are price and quality. Here shows two of our competitors, one is mcdonald which has large market share with low percieved price and quality. Another is a famous snack shop called Fie Jie located in Mong Kok. It is perceived low price and a quite good quality. And you can also see the predicted position of our brand whcih is perceived high price and quality.In order to choose a differentiation and positioning strategy, we need to identify possible value differences and competitive advantages. It is clear that we have product differentiation. First, bur-dle is differ from traditional burgers that bur-dle use noodles instead of breads as the envelope. Second, bur-dle is portable noodles that can take away by hand. These value difference help bur-dle to gain competitve advantage to overcome its bad competitor environment. Then, what differ ence are bur-dle going to promote? The first one is important. Bur-dle is important to our target customers that it is portable and made to order.Portable is important to our target customers that they prefer to eat and walk on the street at the same time. Made to order is important to our target customers that they always prefer a fresh one. The second one is distinctive. Bur-dle is distinctive that it is portable noodles and concern about vegetarians. In fact, we provide bur-dle without meat especially for vegetarians. For value proposition, it is more for more. Bur-dle sells at $25 whcih is generally higher than our competitors, for example mcdonald. On the other hand, bur-dle's quality is high.As mentioned before, bur-dle use meat supplied by companies that have quality guarantee, awards and recognitions. In addition, bur-dle is made to order, which means they are made only when customers order. For the tpye of buying behavior of our target customers, it is variety-seeking buyin g behavoir since there are low comsumer involvement and significant difference among brands. If there is variety-seeking buying behavior, there may be brand switching not because of dissatisfaction, but due to customers want to try new things.

How Will Our Life Go on Without Internet

How will our life go on without internet? It’s hard to imagine that we live in a world without internet which plays an important role in many aspects of our lives. Thus, it’s worth discussing how our life will go on without internet to see what benefits and disadvantages it brings to us. It’s beyond question that our life will be inconvenient if we’re not available to internet. For one thing, we students surf the internet for information frequently in order to write papers, find materials for self-study and so on.In response to the hypothetical situation, we can only go to library for help but the resources there are limited, making us anxious without adequate and prompt information. For another, it’s a waste of time and labor power to put up notices in campus in every aspect. Assume that we should go to somewhere to check messages every day, how troublesome it is for everyone including students and workers in school. Online shopping is so popular f or its multiple choices for us.If not, we’ll spend much more time on selecting goods in real shops if we want to make comparisons. Besides, we’ll lack a lot of fun if we can’t download music or movies. It’s no wonder that a great number of boys will complain about disappearing online games. Certainly, our life will carry on in the assumption, but it won’t be as colorful as today by narrowing our range of entertainment. But, there’re still some advantages in terms of no internet.We’ll spend more time with our family or friends instead of being absorbed in online activities. In addition, we don’t need to worry about false information it delivers and turn our focus on reality, avoiding falling in love with someone deceiving for purposes or students being addicted to internet. To conclude, our life tends to be a mess if we don’t have access to internet. As long as enjoying the convenience, we still need to treat it with rati onality, trying to minish the negative effects as possible.

From Now on, Let Women Kill Their Own Spiders

After reading the two articles â€Å"I Want a Wife† and â€Å"From Now On, Let Women Kill Their Own Spiders†,I find a better way to reduce both women’s and men’s complaints is for women to learn how to love themselves. The first article is written by Judy Brady from the point of view of women; even though is a woman, she wants a wife because a wife does all the housework in a family (Brady 542). In another article, written by Dave Barry, entitled â€Å"From Now On, Let Women Kill Their Own Spiders†, the author humorously appeals to men, telling them not to spoil their wives but to let their wives do their own business, like killing spiders (Barry 539). A woman's love is selfless and fearless; she pays all her attention to family and work. As a professional woman, she needs to work everyday no matter how difficult it is; as a housewife, she needs to keep the house clean and put everything in order; as a mother, she shoulders the responsibility to educate children and create an environment in which children can grow up healthy and happy. Women, you are so silly, when you find your husband paying less attention to you and beginning to complain, you totally lose yourself. So, women, don’t give all your love to others — you should learn to love yourself! To be a better woman, you should learn to appreciate yourself, even if you are just an ordinary woman who does not have a beautiful face or perfect figure. Every morning take a quick shower, put on a simple makeup, and be in a good mood. To be a better woman, you should love yourself and that means not only your appearance but also your inner beauty. Reading some articles everyday or even the newspaper won’t take a long time, but will increase your knowledge. To be a better woman, you should not abandon yourself. Women after getting married, in order to take care of her husband and children, they often give up their hobbies, friends or their own business. Taking time to do what you want is also a way to love yourself. To be a better woman, you should give yourself a beautiful vision and brilliant smile. You should believe that each couple is full of hopes and dreams for their future life together. In the journey of life, no one can accompany you all the time, but yourself. As a result, women must learn to love themselves. Only in this way can your life be filled with confidence and courage and be less lonely and helpless.

Google talks with groupon are ended without deal Essay

Google talks with groupon are ended without deal - Essay Example al Shareholder Services) reported that Google’s overall ranking on corporate governance was just 0.2% in comparison with Standard and Poor’s 500 firms – in other words it outranked just one of the other companies (rankforsales 2004). One of the major areas of concern was the way the founders and other insiders were given extra voting rights through the IPO. These share holders had the power of 10 votes per share as compared to the normal share holders who had 1 vote per share powers (rankforsales 2004). Another concern was that of low independent board membership ratio. This shows that founders of the company have not been too keen on losing control over the reins of the company. Groupon is still a closely held company. The company is expected to grow very fast and is today the number 1 player in its category. The company has been using innovative marketing concept called â€Å"reverse marketing†. Here the company does not force customers to buy through blatant advertising but through providing them with information regarding discounts and gives them the choice to decide which products to buy. The company uses the collective buying concept to offer huge discounts to customers and provide the businesses a huge database. The unique way of business which the company follows has provided the company a negative working capital situation. This means the business gets money upfront from their customers and pay their business partner later on as followed by Wal-Mart also. Mismanagement of the deal seems to be behind this break-off. The problem seems to be the break-up fee that Google has offered. As a part of compliance management, the company which has agreed to be sold is bound by the breakup fee agreement. However, many companies do not comply by the initial agreement and accept counter offers from other firms. In this case Google has publicized about the fee being the dampener. This can be a possible activity to put pressure on the management of Groupon to agree

Colima and Maya's Cultures Essay Example | Topics and Well Written Essays - 500 words

Colima and Maya's Cultures - Essay Example A vessel in form of a dog that considered being an exemplar of Colima culture and vessel with palace scene that determines a Maua culture are fallen under analysis. What should be mentioned is that these works of art have a lot in common, still cultural specialties are visible.  Colima culture or co-called Capacha refers to the territory of West Mexico and â€Å"dated there to the early to middle Formative period† that is 200 BCE-300 AD (Evans and Webster, 95). Death was regarded as a transfer to another world, and burials have attracted special attention in ancient times. â€Å"Ancient West Mexicans used a unique shaft-chamber tomb, an underground series of rooms reached by a narrow, vertical opening, or shaft† (IMA, n.p.). Such vessels have been surrounded the deceased and have put there with a special aim. Dogs have remained to be servants as guides to assist the dead person in his/her trip to the underworld (IMA, n.p.).   In addition, dogs are considered to be a source of food for Colima people that is why such vessel has been of great significance according to the beliefs of that population. The vessel has a dark brown color and rather and size a really small dog. The example of Maya culture belongs to the Late Classic Period in the existence of discussed culture, more exactly 600-900 AD (Foster, 17). â€Å"The culture reaches its artistic zenith† in those times (Foster, 18). That is why the vessel with palace scene is regarded as an important example of Maya culture. This is considered to a vessel for a drink with a painting scene showing â€Å"a ruler sitting on a throne, wearing a jade necklace and a headdress with exotic feathers† (IMA, n.p.). Such vessels also have buried with the people they belong to, usually that have been rich residents of those territories. The vessel is in the different tones of brown and beige color with the size of normal pot or mug.

Religion and Theology Essay Example | Topics and Well Written Essays - 250 words

Religion and Theology - Essay Example The approaches considered in the course's online lesson included the following: Modern Orthodoxy, Habad, Reform, Conservative, Reconstructionist, and Havurah. In addition, some Jews have ceased to practice Judaism entirely, have become non-religious while remaining Jewish culturally (by identity). The Reform Movement is capable of being present in the next 100 years. This is because it has accepted that the world is changing and this particular change is inevitable. The reform maintains that the Judaism and other various Jewish traditions should compatible and modernized with the culture surrounding the Jews (Meyer 45). This will make the Jews be more comfortable to remain religious than to quit altogether. The Jews currently identify with the reform movement more than any other Jew denominations. The percentage is 35% and this is considered high in relation to the other denominations such as Orthodox Judaism or Jewish Renewal movements (Multiple Pew Research Center staff, par. 10). This is another rationale behind why the Reform movement will be present in the next 100 years. The Reform movement has managed to eye the Jewish traditional beliefs though liberal thoughts lens and this has made it successful in incorporating modernity, autonomy, and universalism critical approach in the religion. This has made more Pew Jews to accept it and to increasingly embrace its innovative communal and theological creations. This will definitely be present a century from now.

Violence and Its Impact Upon Adolescents Research Paper

Violence and Its Impact Upon Adolescents - Research Paper Example It was also used to describe to indicate a power relationship that is aimed at constraining or subjecting another person. Over the centuries that followed, violence was given a fundamental role by western civilizations where on one had it was seen to quite fiercely denounce the excesses of violence and openly declared it to be illegitimate, However, on the other hand, Western civilization was also seen to give violence a rather elevated position where it was legitimized so as to validate the actions of knights who were forced to shed blood in the noble defense of the orphans and widows as well as defend the just causes of the Christian kings against the Infidels, and trouble makers (Muchembled 7-9). The brutality of all human relations was accepted as being a universal social language in addition to its being considered to be absolutely normal and quite necessary in most western societies up until the seventeenth century. While cultural ideals might have gradually evolved over time, violence is seen to still play a prominent role in modern society and equally affects people of all ages hailing from the different walks of life. The violence perpetrated against the young people is found to be particularly worrying as it can significantly affect their future development and negatively impact the future human society. There are a number of different development models that are used in the assessment of the impact that violence has on a child’s development. These development models are seen to variously include: The Transactional Model of Development: â€Å"This development model is seen to greatly emphasize the importance of the roles that are seen to be played by both the environment and the child in the determination of the child’s development† (Addison-Scott 17). The main premise of this model is that as opposed to a child acting within its environment, both the environment and the child mutually end up altering each other. Any positive outc omes from this interaction are largely considered to be a consequence of a nurturing environment having been provided to the child while children in a mostly negative environment are normally thought to be at a rather high risk for later difficulties (Addison-Scott 17). According to this model, it can also be argued that a child’s future cannot be solely and accurately predicted by looking at either a single environmental event or a biological event, the model generally assumes that a child’s development is generally made though a reciprocal and bidirectional interaction between the environment and the child (Addison-Scott 17). The transactional model has been largely criticized for the fact that although it attempts to look at the establishment of bidirectional relationships between the environment and the child, it however fails to try and explain the variance that is usually found to exist between them. It is also pointed out that the transactional m

Working while being a college student is bad Essay

Working while being a college student is bad - Essay Example Not every student is fit for a work study but a large number participate in the program since they have no other source of funds to cater for their educational expenses. Working while in college comes with some challenges that pose significant obstacles to the students in their pursuit to attain educational excellence thus making it a bad idea. It is prudent that working while in college is not advisable as it is associated with a number of drawbacks that include; careful in managing time for both the job and school work, stress related to the job as well as the wages earned might induce the students into dropping from their studies to concentrate on those jobs (Perozzi 37). Time is a precious resource for any college students since he/she has to balance all activities to attain both academic and extra curriculum excellence. Part-time jobs while in college come with an additional time obligation since the students concerned will have to set aside between four to twenty hours a week for working depending on the kind of jobs they undertake. That implies that students who take work study programs should have an excellent sense of time management for them to juggle between school work and job obligations. Conversely, a majority of the students who are working while in college they do not evaluate their time management abilities prior to indulging in the program rather the desire to make an extra dollar or rather financial constraints drive them to the program. Often students who do not manage to balance their studies with job obligations end up failing in their GPA or worse situations drop out of college before graduating (48). It is apparent that working w hile at college is something that comes along with extra demand for the students’ time thus imposing additional pressure on their lives a thing that a majority of the students are not capable of handling. Conversely, students are denied the chance to take other

Racial Cultural perceptions of Registered Nurses associated with Dissertation

Racial Cultural perceptions of Registered Nurses associated with screening for PPD - Dissertation Example PPD belongs to a spectrum of psychiatric disorders experienced by women which ranges in severity from maternal blues, which is short-lived lasing from a few hours to a few days, to postpartum psychosis, which is the most severe disorder belonging to this group (Halbreich & Karkun, 2006). The prevalence of postpartum depression varies amongst different socioeconomic, racial, cultural and age groups and can range from 10%-15% in the general population (Driscoll, 2006), to as high as 37% amongst women belonging to lower socioeconomic strata (Segre, O'Hara, Arndt, & Beck, 2010) and 48%, in the adolescent age group (Driscoll, 2006). PPD is thought to occur from interplay between a variety of different factors which can be broadly categorized into three main categories, viz. Biological/Physiological factors, Psychological factors and Social/Cultural factors (Nahas & Amasheh, 1999; Callister, Beckstrand, & Corbet, 2010). Cultural and social factors have been found to play an important role in the etiology of PPD. This has several implications in the screening, diagnosis and treatment of PPD. Since nurses play a pivotal role in screening and diagnosis of postpartum psychiatric disorders, they should be aware of the role of culture in the causation and screening of PPD and should provide ‘Transcultural Care’ as proposed by Leininger (Leininger, 1998). This paper discusses the several cultural factors involved in the causation of PPD, the role of nurses in providing screening and treatment services for women regarding PPD during the postpartum period and the racial cultural perceptions of Registered Nurses regarding the screening for PPD. Etiology of PPD As discussed above, the etiology of PPD is multifactorial. It was previously postulated that PPD was exclusively biological in nature, caused by the drop in the levels of different hormones such as estrogen and progesterone in the body of the mother occurring after the delivery of the baby (Driscoll, 2006). Other biologic/physiological factors implicated in the etiology of PPD include genetic predisposition and physiological disturbances occurring as a result of sleep deprivation, amongst others. However, it has been now elucidated that PPD results from interplay between biologic and environmental factors, including and not limited to, social and cultural factors. Some of cultural factors which have been found to contribute towards the causation of PPD include a history of pre-existing depression in the mother, lack of social support, belonging to a low socioeconomic status, untoward or difficult pregnancy, history of stresses occurring during the postpartum period such as those associated with child care or an infant born with health issues, difficult family relationships, maternal age at the time of delivery and the gender of the newborn, since sons are more desirable than daughters in certain cultures and the birth of a daughter is associated with significant psychological distress (Driscoll, 2006; Goldbort, 2006). As depicted above, cultural influences contribute significantly in the causation of PPD. Thus, any strategies which are aimed at either screening, diagnosing and treating PPD should be tailored in a culturally appropriate manner. The role of Registered Nurses in the management of PPD Nurses play a significant role in the

Prepareabriefingnoteforacolleaguewhohasjustbeenpromotedintoaleadership positionwithinyourorganization,oranorganizationwithwhichyouarefamiliar.Thenoteshould adviseyourcolleagueonwhatlead - Essay Example Secondly, I will brief him on the leadership theories that he could adopt for the effective management of the organisation. Thirdly, I will brief him on team work that is known to be one of the most important aspects of success within contemporary organisations. Finally, I will look into the culture of the organisation and how it impacts on decision-making. There are three important organisational theories namely scientific management, classical and bureaucratic theories. The bureaucratic theory is an impersonal framework and it could have its advantages and disadvantages within the organisation (Argyris, 2012:56). Excluding emotions within the organisation could infringe on creativity among the employees and minimizes the level of conflicts and could be the best approach while dealing with official matters in the business. The second theory is scientific management. This theory mainly focuses on employee motivation within the organisation (Barkin, 2006:13). Employee motivation is viewed as one of the major contributing factors towards success within the company. This is owing to the fact that a motivated work force works hard towards achieving the entity’s goals and objectives (Owens, 2007). This theory however notes that the major aspect contributing to employee motivation is based on compensation. Money is an important motiva ting factor among employees. However, it can be noted that other factors play an important part in employee motivation as well (Owens, 2007). The last theory is the Classical theory that is the most practical for the current situation. This concept takes the idea of employee motivation into a new level (Winkler, 2010:14). This is done by taking beliefs, ideals, values as well as the need for employee satisfaction into consideration (Owens, 2007). This is because intrinsic and extrinsic factors of motivation are important in employee motivation and satisfaction. However, the theory has a major weakness in that it employs

Global Impact Essay Example for Free

Global Impact Essay One of the main attractions of Daylesford, Melbourne is its picturesque, Victorian feel, a legacy of its first settlers. Giving the region a European feel, tourists flock to the area to take in its atmosphere, especially when spas antique and crafts shops and natural therapy centers started to populate the area. A regional park as well as natural springs abounding the area is also an added bonus. Suffice to say, tourism is a main industry for Daylesford, Melbourne. Given this perspective, it is a fair assumption that the region only had to tap these existing resources without much capital, and voila, a thriving tourism industry. Others might argue that there are costs involved in running this kind of industry, but we are under the assumption that whoever coined the place as tourist destinations did not have to capitalize on molding nature according to their preference; it was already there in the first place. There is a need to look into the different aspects of tourism, particularly Daylesford, Melbourne to determine how tourism impacts its citizen’s way of life and standard of living, and see whether tourism is worth the cost on the environment as per benefit. Natural Advantages and Disadvantages Tourism is a two-edged sword. A well-known tourist destination such as Daylesford, Melbourne will benefit from the increase of tourist visiting the area through increase in employment relative to increase in infrastructure development. Other forms of employment will also be available, given that tourism caters to various needs of different people. Locals will experience easier access to livelihood opportunities, thus increasing their average standard of living. Yet, this increase in employment will attract people from other places, not for the sights being promoted by the place but because of employment opportunities. This could result, in an increase in the local population, not necessarily bad if it’s in moderation, but anything more, will congest the naturally quant villages. Not to mention that population increase also increases pollution as well as environmental damages. Employment Generated There are a number of job opportunities that opens when tourism is a big business. In this case, spas and natural therapy centers, means a big boom for the medical industry. People who comes into the area, expects good medical services as well as amenities. Vacation houses and bed and breakfasts also benefits from the influx of tourist visiting the area, providing more jobs for the locals, as well as employing the services of the food industry in area. According to a study conducted by Deloitte Touche, International Institute for Environment and Development (IIED) and Overseas Development Institute (ODI): Limited evidence suggests that domestic/regional tourism and independent travel can create proportionately more local economic opportunities than international packaged tourism†¦Within the tourism industry, the informal sector is often where the poor and women can maximize benefits. (p. 10-11) To expound on this conclusions, the study also mentioned that part of tourism advantages, as a product, it is consumed at the point of production, where other opportunities for enterprising souls are created. It is a labor intensive industry, where there is great opportunity for women in the workforce. Needing very little capital, as its main stock is nature-based; it is a diverse industry that can build upon a wide resource base, where participation of the informal sector is also widely accepted. Changes at the local level to accommodate visitor needs In the case of Daylesford, Melbourne, tourism is indeed an important factor in its economy as well as the rest of Victoria region. In a 2006 brief of the Liberal Party Plans and Policy for the Victoria General Election, tourism was identified as one of the major areas where there will be massive development should they win. Accordingly, Daylesford, Melbourne was identified as one of the areas that need to be focused on. Mentioned in the brief, was that a special attention will be given to recognize the special needs and individuality of rural economies such as Daylesford. (p. 7) According to an article from Media Release last September 27, 2007, the government of Victoria was releasing a considerable amount of money to produce to market tourism in Daylesford. As an offshoot of the tourism industry, the government would like to focus on promoting the area as a destination for gourmet food and wine. It certainly has the appeal and the atmosphere for it. Environmental issues including pollution, traffic and crowding Despite the mentioned beneficial effects of the tourism industry, there are drawbacks. Pollution for instance and it also takes its toll on nature if not managed properly. As mentioned before, the need for employment will draw people to a thriving industry, increasing population, thus, pollution. Offshoot industries can also cause much damage to the environment, where this also leads to pollution. As it is, the environment’s greatest enemy is people itself. People cause traffic, and their bad habits leads to more pollution. Also, the constant wear and tear on the environment, because it is a necessity to cater to tourist’s needs, leaves much to be desired. Many changes will have to occur. Sometimes these changes, causes the decline of what was once beautiful and awe-inspiring. Indeed, tourism is a two-edged sword. Both sides have their considerable argument. Although, there is a way for these arguments to meet half-way, by saying that sustainable development; even in tourism is important. There is a pressing need to preserve and maintain the environment, as well as create new opportunities for the economy to prosper. Sustainability is even more needed in this industry because, on all sides of the economy, the environment is where all industry anchors and depends. REFERENCES: Travelmate. Daylesford Victoria.

Maintain a balance work life for employees

Maintain a balance work life for employees In todays workplace, the environment is constantly evolving. Many of the ideas that will be driven in HR firms will be based upon working to adapt to these changes while being proactive as well. This is the eventuality that must be confronted while trying to maintain a balance work life for employees and manages alike. Measuring performance will take on a new dynamic, as well as, employee/manager interactions. Work will become less bound by the walls of a building in more ways than one. The challenge for many companies will be developing a HR system that is flexible enough to conform to these changes while anticipating the foreseeable future. The HR department of the future must reevaluate the relationship between manager and employee. In many service based organizations, managers function as coaches on the floor. Most commonly in call centers, they listen to prerecorded and live employee/customer interactions. Next, they do an evaluation of the employee and subsequently inform them of strengths and weaknesses. Human resource departments expect managers to use this time to build rapport with their employees while also trying to reinforce a commitment towards accountability. Sometimes there may be a need for corrective action. This requires a manager to tread a thin line between confidant and disciplinarian. Often when these relationships become strained, the HR department works as a mediator to resolve any tension. If the relationship between employee and manager becomes beyond repair, then HR is expected to arbitrate the situation. The survey of 572 Canadian HR Reporter readers and members of the Human Resources Professi onals Association found 95.6 of respondents agree or strongly agree HR professionals have responsibilities that go beyond serving the interest of employers or clients (Klie, May 2010, p 10). Many HR departments seem like they have an issue maintaining this standard. Another survey conducted by Canadian HR Reporter indicated 36.9 percent of its respondents believed that HR usually served in the favor of employers (Balthazard, May 2010, p 11). It is clear that HR must try and maintain the prescience of fairness, in lieu of these glaring statistics: failure to do so could result in tremendous consequences. In situations where productivity is tapering off, HR departments are forced to make decisions that call for radical changes, such as, reassigning manager teams and revisiting employee policies. Adjusting to these changes provide challenges for employees and managers alike. Whenever there is major change, it is the initial transition period that provides the most difficulty. In the event of applying stricter employee/manager regulations, HR departments must anticipate the backlash that maybe pending. It is during this period that employees suffer from lower morale and turnover becomes more prevalent. This makes managing personalities a little more difficult for line managers; therefore, driving a wedge between them and employees. The final prospect that the company is looking at after this fallout is the very real possibility of losing mental and financial capital. Simply put, it costs money and time to train new employees. Hiring a new employee costs $1,580 on average (Hagel, Spring 2007, p 12). This is not a cheap cost for any company to incur and it bound to add up to an immense expense if turnover becomes an issue. The lost of an employee with many years of experience is immeasurable. In short, they tend to make work far more seamless than their less knowledgeable counterparts and dont require as much time for training. One obvious challenge for HR departments headed into this new decade is certain: minimizing turnover in the midst of new employee regulations. In the future, Human Resources will have to find more inventive ways to involve employees and managers in the process of establishing new rules and regulations. This will make employees more knowledgeable of any pending changes on the horizon: minimizing the time and effort it would normally take to retrain current employees. This would not compromise too much since HR heads still maintain the authority of having the final say on matters of policies. What may transpire; however, is a process of educating HR personnel, line managers, and employees alike. Employees tend to be aware of certain nuances of customer interaction that line managers and hr personnel may not be privy to. A few suggestions from the everyday worker could spark better ideas from Human Resources to solve compelling problems that may exist. Managers tend to notice certain trends concerning employee behavior and may also be able to influence more efficient policy as well. Evaluating company rules and mission stateme nts require more than a simple process of crunching statistics: it requires that the application of knowledge obtained from real, at work scenarios be applied and put to practice. The usage of customer, employee, and managerial surveys can make the evaluation process that much simpler while still giving stakeholders some power to influence HRs decision making process. Most importantly, companys maybe able to better engage their employees in the workplace as a result. . A question posed to a communications manager at Coca Cola Enterprises; was summed up with this basic response, Achieving world-class engagement scores is one of our long-term business priorities, so our leaders are committed to it. At a recent conference for our top 300 managers in Europe, they insisted that we devoted an entire afternoon to analyzing the headline results of our latest employee engagement survey and forming some early action plans, which is really encouraging(Strategic Communications Management, Dec 2009/Jan 2010). It is safe to say that engaging employees are a major concern for HR firms. The knowledge of employee engagement can provide the company with an asset vital to understanding just how hard to push workers and when to relent. Employee engagement measurement is most effective when thought of in terms of a series of related inputs and outputs (Brown Kelly, Oct/Nov 2006, p22). HR must be able to decide sufficient factors for deciding which inputs best reflect productivity, in conjunction with, the corresponding outputs. Many companies already use phone, mail, and internet surveys to obtain customer opinions, in order to, develop efficient strategies. . This can be an effective way of getting employee and managerial opinions for the purpose of evaluating engagement. . With the advent of current technology, obtaining this type of information from customers, managers, and employees is just one of the many processes that can be facilitated to make HRs job that much easier. The face of HR is changing quite rapidly. By the year 2020, it is expected that 75 percent of organizations will be outsourcing their HR functions (Millar, April 2004, p 3). .This could possibly provide a better opportunity for HR departments to act in an independent interest. The perceptions of HR are definitely going to change over the course of the upcoming years and will totally require revising even more ideas. According to SHRM research, 80 percent of respondents will increase their use of technology to handle HR transactions (Sandler, Rath, Troy, et al., October 2004). In short, a lot more of the decisions made by HR department will be determined by programs that calculate productivity and monitor spending. The demands of improving the usage of technology must be met with developing hr personnel for management through technology. 57 percent of HR focus survey respondents believed that increased investments in training for HR staff would be vital (Sandler, Rath, Troy, et al., O ctober 2004). It should be noted that with this demand of increased training investments will follow a responsibility to select the most capable candidates for HR, managerial, and employee positions. A study by the Society for HR Management estimates the cost of a poor hire for intermediate positions at $20,000, senior management at $100,000 and sales representatives at $300,000. Pierre Mornell, in his book Hiring Smart, says that if you make a mistake in hiring and you recognize and rectify the mistake within 6 months, the cost of replacing the employee is two and one-half times the persons salary. For example, if you were to use this formula, the cost of a poor hiring decision for a candidate earning $50,000 per year would be $125,000 (Hagel, Spring 2007, p 12). This is a high expense for any company to have to incur. Making the correct hires from the top down would most likely ensure that companies spend less money replacing inefficient workers. It is rather safe to conclude that maintaining a successful corporate takes a lot of careful evaluation. There is a need for affirmative evaluation and not too much guessing. Without a reliable plan, a company could find itself losing tremendous amounts of money and having to spend extra time creating a more effective approach. No company has the perfect method for HR management, in respect to, running an efficient operation. Some companies just realize that aiming towards that goal requires looking at running a company from all angles. This is the ultimate challenge that companies face in the HR sector.

Performance Enhancing Drugs in Sports

Performance Enhancing Drugs in Sports In the world of sports there is much competition. There is so much that many sport players try to cheat their way through by using performance enhancing drugs. The players use steroids, human growth hormones and many more. All performance enhancing drugs should be banned from sports. The history of performance enhancing drugs goes back to the 1800s. There were two reported cases before the 1900s. The first known use was by a 24 year old cyclist named Arthur Linton in 1886. He died in a race from Bordeaux to Paris. The cause of death was said to be Typhoid Fever but he was believed to have taken trimethly which is a stimulant. The second known case happened in 1889. A French physician, Charles Edouard Brown-Sequard, extracted testicular fluid from dogs and guinea pigs and injected himself. At a scientific meeting in Paris he announced his findings saying that it made him feel younger and have more energy. In 1935 German scientists, led by Adolf Butenandt, developed the anabolic steroid. Between 1940 and 1945 the Nazis began testing the steroids on humans. They used prisoners, Gestapos, and Adolf Hitler himself. They found that it causes aggression and with enough use it causes people to go crazy. In 1954, the United States was given Performance- Enhancing drugs. When the Russians began to become good at powerlifting, a Soviet team doctor revealed his teams use of testosterone injections to an American weightlifting doctor named John Ziegler. Ziegler then began to work on creating a refined synthesis that would produce a compound with muscle-building benefits of testosterone but without bad side effects such as a prostate enlargement. The drug he created, called Methandrostenolone, was released by Ciba Pharmaceuticals under the name Dianabol. In 1973, the German womens swim team won 10 out of 14 gold medals in the inaugural swimming world championships in Belgrade. As a result, the Olympic committee in 1975 put anabolic steroids on a list of banned substances from the Olympics. Also, on the list, at that time, were any kinds of stimulants. In 1983, the governing body of Pan Am stripped 3 gold medals from American weightlifter Jeff Michels and they took gold medals from 3 other Latin Americans for testing positive of anabolic steroids. Thirteen other members of the American track and field team withdrew from the Olympics. Overall 23 medals were taken, 11 of them being gold. In 1988, sprinter Ben Johnson smashed the one hundred meter time by .14 seconds with a time of 9.79 seconds. He was then tested for anabolic steroids. He tested positive and his world record was deleted from the record books. In 1990 the government stepped in and Congress passed the Anabolic Steroid Control Act which classifies steroids as a Schedule III controlled substance. This means that the trafficking of Anabolic Steroids is no longer a misdemeanor but a felony. In 2000, Urinalysis tests are improved to detect EPO (erythropoietin). At this time though, blood doping was still undetectable. There are many dangerous risks around blood doping which consist of blood clots, strokes, and thrombosis. After retiring from baseball in 2002, Kem Caminiti admitted that he used steroids in his 1996 National League Most Valuable Player award winning season. He is quoted saying â€Å"I have made a ton of mistakes. I dont think using steroids is one of them.† In 2004 he died of a heart attack. He was only 41 years old.(Sports Illustrated) The most recent major case of steroid usage is with Barry Bonds. He was an outfielder for the San Francisco Giants and was first accused of using steroids in 2003 but denied ever using any. The government accused him when they went to his trainers house and took papers saying that Bonds had been using an undetectable steroid. He was found guilty on obstruction of justice on April 13, 2011 Performance enhancing drugs should not be used in any sports. They can be harmful to the human body, gives players an unfair advantage, and it does not show true skill. Many athletes, because of their drive to win, take too high a dose of Performance-Enhancing Drugs causing a high health risk. Both men and women can get bad side effects from them such as an increased risk of tendonitis, liver abnormalities and tumors, hypertension, heart and circulatory problems, prostate gland enlargement, aggressive behaviors, psychiatric disorders, and inhibited growth and development. Many of these are life threatening. Taking these drugs could be considered cheating as well. While there may be many players in sports taking Performance-Enhancing Drugs, there are still many who do not. For the ones who do not use them they put in hours and hours of hard work to get stronger for the sport they play. Athletes that do take them get the same effect in a much shorter time frame and many of the drugs they take gives them more energy to work out harder and longer. They also do not show the true skills a player may possess. For example, if a baseball hitter is a weak hitter but then takes steroids and works out while he is on them and gets really big and strong and starts crushing the baseball, he is showing the skills that the drugs helped him create. A Tuft University study showed that steroids can increase home run production by 50 percent showing that steroids are the reason why this weak hitter started crushing the baseball. Steroids help people get stronger a lot faster than if they did not take them. There are also some good things that come of Performance-Enhancing Drug use in sports. More world records are set, if it was legal then less time and would be used to enforce the drug policy, and the focus turns away from the drugs and back onto the sport that is being played. All of these reasons can all make the sport be more entertaining. Since these Performance-Enhancing drugs make athletes stronger, more records would be set. A study by a Tuft University physicist found that, on average, taking steroids increases the kinetic energy in a baseball players swing by about 10 percent, raises his bat speed by about 5 percent, and boosts the velocity of the hit ball by about 4 percent. These small increases all cause baseballs to travel farther and give players a 50 percent increase in homerun production which makes home run titles much easier to obtain. (Washington Post, Vedantam) Performance-Enhancing drugs dont only help baseball players break records, they help all sports. A sprinter by the name of Ben Johnson crushed the previous 100 meter dash record by .14 seconds with a time of 9.79 seconds. After the record breaking feat, he was tested for steroids and the results came back positive causing his record to not count. He would have had sole possession of the record if not for steroid bans. A weightlifter by the name Jeff Michels won 3 gold medals in the 1983 Olympics because of his use of steroids. His medals were stripped because he tested positive for steroids but that helps to show that steroids do help athletes become stronger and provide for tougher competition. This tougher competition would make people work harder to strive for their goals that they want to achieve. Money can also be saved if athletes could use Performance-Enhancing drugs. Instead of spending money on doctors to test players and investigators to investigate the players found using the drugs, they could just let it all go and save millions of dollars. With the money they save they could buy new equipment for each team. It would also give the leagues more time to decide on ways to make money. The focus of league officials would come back to the sport being played. Instead of them worrying about who has been taking Performance-Enhancing drugs and how long they need to suspend that person for, they could worry about who hit a walk-off homerun in the bottom of the 9th or who just won the gold in the Olympics all without worrying about what they did to get so good. Performance enhancing drugs should not be allowed in any sport ever and the government should stay out of the entire struggle with these drugs in sports. The problems with Performance-Enhancing drugs has increased over the years but if the government stepped in and tried to deal with it, it would just give them another responsibility that they may not be able to handle. They may also be able to take steps that are too drastic such as throwing people in jail. Performance enhancing drugs are very harmful to the human body and should never be used in sports. They cause many life threatening sicknesses such as heart attacks and heart disease. They also provide unfair advantages and do not show an athletes true skill. There are good sides to it as well such as the added strength it gives athletes causes better records, more home runs, faster people, if they were legal then less time would be used to enforce the drug policy, and they would turn the focus away from drugs and back to the sport being played. Even with the good that can come out of Performance Enhancing drugs they are not worth the fatal risks and being known as a cheater for the rest of an athletes career. Keep all Performance Enhancing drugs out of sports forever. Performance Enhancing Drugs In Sports Performance Enhancing Drugs In Sports Performance enhancing drugs have been used in sports for years. Professional athletes like Barry bonds, Mark McGuire, and Lance Armstrong have been using PEDs for years. Sjà ¶qvist, Garle, Rane, states, Notable examples include Ben Johnsons gold medal for the 100 m at the Seoul Olympics in 1988, and hundreds of other winning elite athletes who have been caught in doping tests (Sjà ¶qvist, Garle, Rane, 2008). Some athletes who take PEDs try not to get caught. There are some athletes who are unaware that they have used performance enhancing drugs. Performance enhancing drugs has caused a serious debate over whether or not to ban PEDs. Performance enhancing drugs damages the integrity of sports and is harmful to the health of the athletes. There are others who believe performance enhancing drugs provides an extra performance increase. Performance enhancing drugs are substance that is used by athletes or people to improve their performance. Some athletes believe it is necessary to us e performance enhancing drugs in order to excel in their performance in sports. . Young athletes are at risk of using performance enhancing drugs because of peer pressure. Also they are at risk because the need to win and to perform better. A debate about the NCAA drug test program is about how the program test athletes for drug use. One reason for the controversy is the program check for certain drugs when they should check for all drug types. It is a suitable moral problem because it is a controversial issue where people can disagree about legalizing or banning performance enhancing drugs in sports. Many people believe that athletes who use performance enhancing drugs are morally wrong, and it is cheating and harmful to the athlete health. One of the major justifications for banning performance enhancing drugs is the health risks to athletes. The second reason is performance enhancing drugs cause damage to the integrity to sports. The third reason is the performance enhancing drug s encourages cheating and dishonest behavior in athletes. Identify the Problem Performance enhancing drug destroy the integrity of sports and it harm the health of the athlete. Clarify Concepts The terms I am planning to define in my paper are performance enhancing drugs, doping, and fairness. Performance enhancing drug is defined as a substance that is used to provide athletes with advantage in athletic performance. An idea that needs clarification is doping can be define as substance that athletes takes in any unfamiliar form to the body used gain an advantage in athletic performance. Another idea needs clarification is that of fairness itself, especially the idea when an athlete is cheating. The accusation is that when athletes takes performance enhancing drugs it is a form of cheating, that is unfair to the athletes when do not use PEDs. Some of the performances enhancing drug use by athletes are stimulants and pain suppressions. Anabolic agents are used by athletes for muscle building. Anabolic agents are also used as training aids by athletes. Some athletes take anabolic agents to recovery from train loads. Athletes some time take several different types performance e nhancing drugs. Diuretics used to control weight and Peptides are taken by athletes for many different reason. Peptides are also used because it is difficult to detect. Athletes take diuretics when they want to lose weight quickly. Athletes have been aware of the benefits that come from blood doping. Some athletes use blood doping used to increase oxygen in tissue. The reason athletes like using blood doping because it is difficult to detect. There are also some side effects from using blood doping like renal failure. Athletes use B Blockers use to control anxiety. Amateur athletes such as football, basketball and baseball players are a lower level athlete than professional. Amateur athletes play in sports in college. Amateur athletes do not earn a paid salary. Professional athletes are higher level and they get paid a salary. Professional athletes can play for sports such as the NBA, NFL and MLB. Wiesing states, Sport is an artificial setting, created by human beings, in which the competitor is required to perform, at least according to current, widely prevalent belief, with a degree of naturalness (Wiesing, 2011). The different kinds of drugs being abuse by athletes are stimulants, pain suppressions, anabolic agents, diuretics, Peptide, blood doping and B Blockers. Identify Possible Solutions to the Problem Allowing performance enhancing drugs in sports is an ethically sound solution when having to deal with the fairness. One possible solution is to allow athletes to take performance enhancing drugs under medical supervision. Another possible solution is to administer drug testing among athletes. It performance enhancing drugs was to become legalized then those who chooses not to used them will not be able to compete. Banning performance enhancing drugs is the ethically sound solution when having to deal with the integrity of the sport, and cheating and it harms the health of the athlete. A final possible solution allows athletes to take performance enhancing drugs at their own risk. Gather Information An athlete who uses performance enhancing drugs is judged differently than student who uses substances. Athletes who use performance enhancing drugs will be judge as cheaters. They also find that students who use performance enhancing drugs are judge differently than athletes. Some athletes believe it is necessary to use performance enhancing drugs in order to excel in their performance in sports. Copeland, Peters, Dillon states, The strongest motives for misuse of AS are to improve athletic performance, to enhance muscle mass for purposes of bodybuilding, or to improve physical appearance (as cited in Dodge, Wiliams ect, 2012). The perception that athletes who uses performance enhancing drug is the unfairness. An athlete who takes performance enhance drugs is a form of cheating that is why it is unfair. The reason for the perception is athlete who takes performance enhancing drugs and wins is because of the drugs. Also the athletes success was achieved at the expense of another ath lete. The thesis is, the use of performance enhancing drugs in youth athletes. The article examines the use of PEDs by youth athletes. Young athletes are at risk of using performance enhancing drugs because of peer pressure. Also they are at risk because the need to win and to perform better. A third reason why young athletes are at risk of using performance enhancing drugs is because competing with pain. The thesis is the NCAA drug test of athletes uses performance enhancing drugs in sports. Athletes in all sports are given a drug test. The NCAA drug testing program has been debate since it started random drug testing athletes. Some of the athletes who were drug test do not use performance enhancing drugs. A second debate about the NCAA drug test program is about how the program test athletes for drug use. One reason for the controversy is the program check for certain drugs when they should check for all drug types. A third issue with the drug test program is the drug test untrustworthiness of the test results. The test results can come back positive even if the athletes are not using PEDs. For example if a female takes birth control it can cause the drug test come back positive. A positive drug test can cause problems for an athlete career. Critics of drug testing argue that it is unfair to pick certain athletes for inspection because it could tempt some to cheat. Athletes attitude toward athletes who uses PEDs feels it is unacceptable. Some athletes felt they did Performance enhancing drugs has been used in sports for years. During modern Olympic Games, the drugs athletes choose to use included strychnine, heroin, cocaine, and morphine. In the early 1950s performance enhancing drugs was used in sports before that it was used by soldiers in the war. Tour de France cyclist Tom Simpson died from amphetamine abused. Amphetamines became a popular stimulant among professional athletes. Amphetamines have side effects such an aggression and addiction. In 1960 the first doping accident was seen during the Olympics. In the early 1950s anabolic steroids was introduce in sports. During the tour de France a doping death took place. There has been evidence that suggest the growth hormones increase an athletes performance. It was not until the 1976 Olympics game was AAS was tested in athletes. Some performance enhancing drugs are harder to detect because it mimic the body natural chemicals. The use of PEDs by athletes has led to an increase of recreational drug use among athletes. Some athletes used PEDs to decreased fatigue during exercise, reduce inflammation and boost their mood. Noakes states, Increasing muscle size, these drugs increase strength, power, and sprinting speed; they also alter mood and speed the rate of recovery, permitting more intensive training and hence superior training adaptation (Noakes, 2004). Should performance enhance drugs in sports be legalized under medical supervision, the outcome and the risks will affect the athletes. Some of the most memorable moments achieved in sports were achieved by some professional athletes using performance enhancing drugs. Some argue performance enhance drugs should be legalized in sports. If performance enhance drugs was to become legalize in sports there needs to be rules and restrictions. The legalization performance enhancing drugs becomes under medical supervision means there will be a list of risks and side effects. Also there will be an introduction to the long term damage performance enhancing drugs causes to the athletes health. Even if performance enhance drugs was to become legal some PEDs will still remained banned. Some athletes lack understanding of the side effects of using PEDs especially when it comes to new PEDs. If performance enhance drugs were to become legalized under medical supervision who will decide how much can b e use or place limits on use. Some who support performance enhancing drug use under medical supervision believes if it was to become legal if would lead to an increase of drug testing on athletes. Wiesing states, Sport in general and the credibility of the doping control system in particular are suffering from the fact that not all doping activity can be verified because doping methods change (Wiesing, 2011). The impact of legalizing performance enhancing drugs in sports would lead to athletes taking more risks to their health using PEDs. Those who oppose the legalizing performance enhance drugs in sports believes the risk can be avoided by not allowing PEDs sports. If performance enhancing drugs was to become legal in sports it would change our view of sports. Also many believe that achievements in sports are accomplished through hard work, natural talent and not by using performance enhancing drugs. Sjà ¶qvist, Garle, Rane, states, Athletes commonly take mega doses of steroids-d oses 50-100 times the amount needed to replace physiological steroid concentrations (Sjà ¶qvist, Garle, Rane, 2008). Some athletes use blood doping used to increase oxygen in tissue. Examine Assumptions and Points of View There are some assumptions that are made about the moral acceptability of performance enhancing drugs in sports. What we believe is right determines our beliefs about what makes performance enhancing drugs acceptable or unacceptable in sports. Some people assume an answer to the problem is to fully accept performance enhancing drugs in sports. Performance enhancing drugs is considered illegal if it violates the spirits of sports. Those who support performance enhancing drugs in sports claim that performance enhancing drugs have been used for years. Those who favor the use of PEDs claim the reason many have fail to eliminate performance enhancing drugs in sports because of lack of evidence to support their claim. One argument in support of performance enhancing drugs claims that if they were made legal there would be no issue with cheating. In addition if performance enhancing drugs are made legal the playing field will be leveled. Those who favor claims performance enhancing drugs do not change the spirit of sports; instead they claim it helps the sport. Athletes who have use performance enhancing drugs have benefit from the advantage over other athletes. In addition they have also benefit from a salary increase as a result of taking steroids. There is the argument that the performance enhancing drugs that are safe should be allow and that those that are not should be banned. They also argue if safe performance enhancing drugs were allow then it will force companies to create safe PEDs for athletes to use. The opposing side claims performance enhancing drugs changes the fairness of the game. In addition, taking performance enhancing drugs it is considered cheating. There some who argues that when dealing with the unfair advantage some people have the ability to win. The athletes ability to win depend on how much oxygen is carried to the muscles. There is other who relies on performance enhancing drugs to compete. If performance enhancing drugs became legal in sports, it would take away the spirit of the sport. The opposing side claims performance enhancing drugs are dangerous as they put the health of the athlete at risk. It is unfair to the athletes who do not take PED because of the advantage that the cheater gains. It performance enhancing drugs were to become legalized, and then those who choose not to use them will not be able to compete. Moral Reasoning My solution to the problem is performance enhancing drugs should be banned because they damage the integrity of sports. The problem is to determine whether or not performance enhancing drugs is morally acceptable in sports. Because performance enhancing drugs involves athletes cheating or unfairness. This is the argument the opponents of performance enhancing drugs appeal to in their claim. Performance enhancing drugs harm the health of athletes and cause unfairness. Athletes can suffer long term side effects from using performance enhancing drugs. An athlete who takes performance enhancing drugs has an unfair advantage over athletes who do not take PEDs. Those who choose not to use performance enhancing drugs will be force out. Those who are in favor of performance enhancing drugs in sports often appeal to these arguments prevent unfairness and health. We must take into consideration the harm and the benefits of using performance enhancing drugs. Waller states. deontology ethics def ine as any ethical system that judges right and wrong acts in terms of principles or duties, rather than on the basis of the consequences of the acts; contrasted with consequentialism (Waller 2011, 343). Deontology would say using performance enhancing drugs is cheating and it is morally wrong. Athletes that value the integrity of sports would not use PEDs. Athletes have to consider duties or obligation they owe to the other athletes and others to treat others with respect. To cheat in sports by using PEDs or mislead someone by lying about the use of performance enhancing drugs is disrespectful and is wrong in the eyes of a deontologist. An athlete who takes performance enhancing drugs in sports is unethical. People should be treated as ends never as the means. Deontology places importance on the kinds of acts the athlete do and justice. Any athlete who uses PEDs is immoral and the uses PEDs by athletes should not be accepted. Conclusion and Consequences Sports have always been important to many people in society. The use of performance enhancing drugs in sports undermines the integrity of sports and creates an unfair advantage. An athlete who takes performance enhancing drug has an unfair advantage over other athletes who do not take PEDs. It is not fair to the athlete who chooses to obey the rules. PEDs are not only harmful to the health of the athletes but it is also a form of cheating. If my solution was to become law or policy it would bring fairness to sports and moral integrity as well. Also there will be the policy of the risk of performance enhancing drugs to the health of the athlete. The side effects can include renal failure, addiction, blood pressure increase and change in body temperature. One of the arguments is taking performance enhancing drugs are against the rules for athletes to use performance enhancing drugs. The second argument is the unfairness an athlete who uses PEDs has over an athlete who does not use drug s. The third argument is the harm performance enhancing drugs are to the athletes health. A final argument is the use of performance enhancing drugs in sports undermines the integrity of sports. The opposition objects to the harm of PEDs and unfairness. The risks that come from using PEDs should not be left up to the athlete. If an athlete is caught using performance enhancing drugs they could be suspended from the league.

Syndication of the Web 'Syndication involves the sale of the same good to many customers, who then integrate it with other offerings and redistribute it (Werbach, 2000).'; E-Trade is one such organization. They distinguish themselves from their competition by the way they package and price the information they sell not through the information itself. Syndication is a very different way of structuring the business of today. This way of doing business is very different than the way business has been done in the past. It requires small and large businesses to rethink their tactical and strategic plans, thus causing the reshaping of organizations. This will also change the way they interact with customers and partner with other entities. In addition, businesses will be forced to develop new models for collecting revenues and earning profits. Syndication has traditionally been rare in the business world for three reasons. First, syndication works only with information goods. Second, syndication requires modularity. Third, syndication requires many independent distribution points (Werbach, 2000). Within this syndication network, businesses can play three different roles or a company can play one role in a syndication network, or two or three roles simultaneously. The three roles are originators, syndicators, or distributors. The originators create the original product or content. The syndicators package the content for distribution to the distributors. Often times they integrate it with the product or content from other originators. And last but not least, the distributors deliver the content to customers (Werbach, 2000). Within the structure of syndication there are syndicators and distributors. Syndicators save the distributors from having to find all of the different originators in an effort to gather all of the content that they want to package and eventually put out for distribution. The syndicators are able to collect standard formats and contracts from a variety of sources and making it readily available. This part of the process frees the distributors from having to find and negotiate with dozens or even hundreds of different originators. This allows syndicators to act as information collectors by collecting and packaging digital information in a way that adds value to it. In the physical world, it is very difficult to find a syndicator that works alone and is not associated with the entertainment industry.

Partial Birth Abortion Act November 5, 2003 :: Government Politics Abortion Essays

Partial Birth Abortion Act November 5, 2003 On November 5, 2003 President Bush placed a national ban on partial birth abortions. This was an act that many felt was outdated. The same proposal was brought upon President Clinton in 1995, but he vetoed it saying it was a birth mother’s right to choose the fate of her unborn child. A partial birth abortion is the process of removing a fetus from the mother just prior to its birth. This procedure is not painless for the mother, or the fetus. The actual procedure involves removing the child limb by limb from the womb. After the initial limb removal, scissors are forced into the child’s skull and a suction tube is inserted to remove the brains of the child. President Bush’s press secretary, Hatsuhisa Takashima, wrote this speech. The author utilizes the problem/solution argument structure and the rhetorical appeals within his speech. The problem/solution that is apparent in the text of this speech is obvious from the very beginning. The President says, â€Å"that the American government has looked away from this violence, but now the government has confronted the violence and come to the defense of the innocent child.† The partial birth abortion was once seen as a medically necessary procedure, but the President points out it is, â€Å"not only cruel to the child, but harmful to the mother, and a violation of medical ethics.† The elected branches of government have worked together to prevent this practice as a means of a solution to the partial birth abortion situation in this country. The signing of the Partial Birth Abortion Act of 2003 shows a major solution by not allowing the problem to continue. In addition to the problem/solution argument structure this speech has ethos mixed in it also. Hatsuhisa Takashima, the author of this speech, held many high titles in his years working in Japan. Just before being appointed to be the Press Secretary of the United States of America he was the General of Administration and Broadcasting Corporation in Hong Kong. Before being appointed to that title he was the Director of United Nations Information Center in Tokyo. He has been involved in a journalism career for most of his life and his writings have been well acclaimed. In the speech he says many facts that lead one to believe that the banning of partial birth abortions is the best solution to the problem.

Urban Safari :: Free Essay Writer

Urban Safari There are times when having a brother with twenty more years of age, experience, and wisdom, can adversely effect your credibility. This is especially true at nine years old. I found this to be the case one Christmas day many years ago when my brother Tom came home for the holidays. It appeared to be the start of a special Christmas, for my brother was coming to visit. I was even more excited than usual for a nine-year-old boy at this time of year. I wondered what new presents would be under the tree? In the past, Tom always got me such neat stuff. I could hardly wait to start shaking the gifts and guessing. As usual, I was up before dawn, tearing into my gifts with all the fervor with which the drowning seize life preservers. My folks, along with my brother, had now joined me in the gift-opening ceremony. Saving the best for last was out of the question; it was the gift from my brother that I tore into first. My dreams had come true. My prayers were answered. There it was, bigger and shinier than anything in the display case of any Western Auto store in the world. It was a B B gun. Finally, I had entered the ranks of the big kids. The prestige of such a gift! I anticipated the glory of shooting my first bird. This was truly a present for a twelve years old, maybe even a teenager. While reveling in my grandeur, I hadn't noticed that my Mother was watching with obvious disapproval. Apparently she had other plans for the B B gun. "You can't shoot that thing in the yard!" she barked. "You'll have to go to the riverbed." With those words, I was instructed to leave the B B gun under the tree with the less attractive presents. "You can open your other gifts now. Tom will watch you while we go visit Auntie Mabel, and don't forget, leave the B B gun alone," Mom ordered. No sooner than they were out the door my brother grabbed the gun and headed towards the back yard. "Where’re you going?" I asked. "To test your gun out before Mom and Dad get back" was his reply. I thought this was a grand idea. Our back yard was full of potential targets. My brother's first choice was two cases of empty mason jars my Mom used for canning fruit.

SENSE OF SIGHT†¦. The eyes are sensory organs. They keep the brain updated with information about is what happening around the body. Both contain millions of tiny sensors that send messages along nerves to the brain. Sensors in the eyes respond to light and, through the brain, let us see the world. Sensors in the skin respond to touch and allows us to feel. * * * * The seeing eye†¦ Light enters the eye through the clear cornea. It then passes through the pupil and is focused by the lens on the retina. This thin layer covers the back of the eye and contains cells that are sensitive to light.When light hits the cells, they send signals to the brain. There, the signals are turned into pictures so we can see. Telescope†¦ A  telescope  is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation  (such as  visible light). The first known practical telescopes were invented in the  Netherlands  at the beginning of the 17t h century, using glass lenses. They found use in terrestrial applications and astronomy. Within a few decades, the  reflecting telescope  was invented, which used mirrors.In the 20th century many new types of telescopes were invented, including  radio telescopes  in the 1930s and  infrared telescopes  in the 1960s. The word  telescope  now refers to a wide range of instruments detecting different regions of the  electromagnetic spectrum, and in some cases other types of detectors. History†¦ The earliest recorded working telescopes were the  refracting telescopes  that appeared in the Netherlands  in 1608. Their development is credited to three individuals:  Hans Lippershey  and Zacharias Janssen, who were spectacle makers in Middelburg, and  Jacob Metius  of Alkmaar. 4]  Galileo  heard about the Dutch telescope in June 1609, built his own within a month,[5]  and greatly improved upon the design in the following year. The idea that the  ob jective, or light-gathering element, could be a mirror instead of a lens was being investigated soon after the invention of the refracting telescope. [6]  The potential advantages of using  parabolic mirrors—reduction of  spherical aberration  and no  chromatic aberration—led to many proposed designs and several attempts to build  reflecting telescopes. 7]  In 1668,  Isaac Newton  built the first practical reflecting telescope, of a design which now bears his name, the  Newtonian reflector. The invention of the  achromatic lens  in 1733 partially corrected color aberrations present in the simple lens and enabled the construction of shorter, more functional refracting telescopes. Reflecting telescopes, though not limited by the color problems seen in refractors, were hampered by the use of fast tarnishing  speculum metal  mirrors employed during the 18th and early 19th century—a problem alleviated by the introduction of silver coated g lass mirrors in 1857,[8]  and aluminized mirrors in 1932. 9]  The maximum physical size limit for refracting telescopes is about 1 meter (40  inches), dictating that the vast majority of large optical researching telescopes built since the turn of the 20th century have been reflectors. The largest reflecting telescopes currently have objectives larger than 10  m (33  feet). The 20th century also saw the development of telescopes that worked in a wide range of wavelengths from  radio  to  gamma-rays. The first purpose built radio telescope went into operation in 1937. Since then, a tremendous variety of complex astronomical instruments have been developed.How to use†¦ * Find an area where the items you wish to view aren't obstructed by trees to set up your telescope so that you get a clear view of the sky. * Look to see if your telescope has a polar axis. If it does, it will track whatever you are looking at. If you have a telescope with a polar axis, follow your manufacturer's directions on how to align the polar axis and the finder scope. * Select the eyepiece with the lowest magnification that you have. Always start with the lowest magnification eyepiece until you become more experienced in using your telescope. Locate the item in the night sky that you wish to observe and focus in on it. Move the planet or star you are viewing as close to the center of the field of view in the eyepiece as possible. * Remove the low magnification eyepiece and replace it with an eyepiece with a higher magnification. * Readjust the alignment of the telescope when the planet or star drifts out of view if you have a manual telescope mount. * Continue in this manner, observing different visible planets and stars. Binoculars †¦Binoculars,  field glasses  or  binocular telescopes  are a pair of identical or mirror-symmetrical  telescopes  mounted side-by-side and aligned to point accurately in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from  opera glasses  to large pedestal mounted military models. Many different abbreviations are used for binoculars, including  glasses, nocs ,noculars ,  binos  and  bins. Unlike a (monocular) telescope, binoculars give users a three-dimensional image: for nearer objects the two views, presented to ach of the viewer's eyes from slightly different viewpoints, produce a merged view with an  impression of depth. History †¦ No sooner was the telescope invented in than the early 1600s than did astronomers get the idea of mounting two of them together, effectively inventing the first binoculars. Galileo (who is often falsely credited with having invented binoculars) adapted an earlier design, using optics that combined convex and concave lenses to create a magnifying effect just like that used today in the cheapest nonprismatic glasses marketed for sports or theater viewing, or for use by children.In the mid-1850s, Ignazio Porro of Italy patented a design using two prisms constructed in a Z shape to present the viewer with an image that not only is better magnified, but has depth. The Porro prism design was followed a few decades later by the roof prism, in which the prisms are constructed in one unit. Soon, binoculars were adapted for military use, and were employed during the Civil War. Quality made a big jump around the turn of the 19th century, and continued to be refined in the early 1900s. With the advent of World War II, more manufacturers entered the binoculars market, including, in the United States, Bausch ; Lomb.Germany continued with its production of highly regarded binoculars, with a few changes. For example, Zeiss, one of the top names in binoculars, experienced a confusing shift, with a new factory established in East Germany under Russian control with the Zeiss name while another factory named Zeiss was b egan exporting from West Germany, according to a history in the 1961 book Binoculars and Scopes and Their Uses in Photography, by Robert J. and Elsa Reichert. Japan exports binoculars via various manufacturers, and some U. S. ompanies import Japanese-made binoculars but sell them under the U. S. company name. How to use†¦ * Put the binocular strap around your neck. Wearing the neck-strap gives you the ability to use both hands while you are using the binoculars. * Adjust the barrels of the binoculars — each side you look into — to the width of your face. Generally, all you need to do is move the barrels closer together or further apart as you hold the binoculars up to your eyes. If you have adjusted the binoculars correctly, you should not see a black â€Å"border† when you look through the eyepieces. Locate the central focus wheel, usually in the middle of the two barrels of the binoculars. Turn the wheel slowly as you look at a particular object in the di stance to get the best focus for your eyes. * Fine-tune your viewing even more if you have a diopter focus mechanism on your binoculars. Not all binoculars have this focus element, which helps compensate for the difference in vision that you might experience in each of your eyes. The diopter focus adjustment wheel is usually on the right-hand barrel. * Keep both eyes open as you view your target objects.You might need to re-focus from time to time. * Clean your binoculars after using them. A soft, damp cloth is sufficient for the body of the binoculars. Treated tissue paper used to clean cameras and eye glasses is safe for wiping the lenses. Store binoculars in their carrying case when you're not using them. Microscope †¦ A  microscope  (from the  Ancient Greek:   ,  mikros, â€Å"small† and   ,  skopein, â€Å"to look† or â€Å"see†) is an  instrument  used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called  microscopy .Microscopic  means invisible to the eye unless aided by a microscope. There are many types of microscopes, the most common and first to be invented is theoptical microscope  which uses  light  to image the sample. Other major types of microscopes are the  electron microscope  (both the  transmission electron microscope  and the  scanning electron microscope) and the various types of  scanning probe microscope History †¦ The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. An early microscope was made in 1590 in  Middelburg, Netherlands. 1]  Two  eyeglass  makers are variously given credit:  Hans Lippershey   (who developed an early  telescope) and  Zacharias Janssen. Giovanni Faber  coined the namemicroscope   for  Galileo Galilei's compound microscope in 1625  [2]  (Galileo had called it the â€Å"occ hiolino† or â€Å"little eye†). How to use†¦. * When moving your microscope, always carry it with both hands (Figure 1, below). Grasp the arm with one hand and place the other hand under the base for support. * Turn the revolving nosepiece so that the lowest power objective lens is â€Å"clicked† into position (This is also the shortest objective lens). Your microscope slide should be prepared with a coverslip or cover glass over the specimen. This will help protect the objective lenses if they touch the slide. Place the microscope slide on the stage and fasten it with the stage clips. You can push down on the back end of the stage clip to open it. * Look at the objective lens and the stage from the side (Figure 2) and turn the coarse focus knob so that the objective lens moves downward (or the stage, if it moves, goes upward). Move it as far as it will go  without touching the slide! * 5.Now, look through the eyepiece and adjust the illuminator (or mirror ) and diaphragm (Figure 3) for the greatest amount of light. | | | * Slowly turn the coarse adjustment so that the objective lens goes  up  (away from the slide). Continue until the image comes into focus. Use the fine adjustment, if available, for fine focusing. If you have a microscope with a moving stage, then turn the coarse knob so the stage moves downward or away from the objective lens. * Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image. Now, you should be able to change to the next objective lenses with only minimal use of the focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place. Do not allow the objective lens to touch the slide! * The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye op en (this helps avoid eye strain). If you have to close one eye when looking into the microscope, it's ok. Remember, everything is upside down and backwards.When you move the slide to the right, the image goes to the left! * Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses. * When finished, raise the tube (or lower the stage), click the low power lens into position and remove the slide. * Always keep your microscope covered when not in use. Submarine†¦ A  submarine  is a  watercraft  capable of independent operation underwater. It differs from a  submersible, which has more limited underwater capability. The term submarine most commonly refers to a large crewed autonomous vessel.However, historically or colloquially, submarine can also refer to medium-sized or smaller vessels (midget submarines,  wet subs),  remotely operated vehiclesor  robots. The adjective  submarine, in terms such as  submarine c able, means â€Å"under the sea†. The noun  submarine  evolved as a shortened form of  submarine boat(and is often further shortened to  sub). [1]  For reasons of  naval traditionsubmarines are usually referred to as â€Å"boats† rather than as â€Å"ships†, regardless of their size. Although experimental submarines had been built before, submarine design took off during the 19th century, and they were adopted by several navies.Submarines were first widely used during  World War I  (1914–1918) and now figure in many large  navies. Military usage includes attacking enemy surface ships or submarines,  aircraft carrier  protection,  blockaderunning,  ballistic missile submarines  as part of a nuclear strike force,  reconnaissance, conventional land attack (for example using acruise missile), and covert insertion of  special forces. Civilian uses for submarines include  marine science, salvage, exploration and facility inspec tion/maintenance. Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or  undersea cable  repair.Submarines are also used in tourism, and for  undersea archaeology. Most large submarines consist of a cylindrical body with hemispherical (and/or conical) ends and a vertical structure, usually located amidships, which houses communications and sensing devices as well as periscopes. In modern submarines this structure is the â€Å"sail† in American usage, and â€Å"fin† in European usage. A â€Å"conning tower† was a feature of earlier designs: a separate pressure hull above the main body of the boat that allowed the use of shorter periscopes.There is a propeller (or pump jet) at the rear and various hydrodynamic control fins as well as ballast tanks. Smaller, deep diving and specialty submarines may deviate significantly from this traditional layout. Submarines have one of the largest ranges of capabilities in any vessel, ranging from small autonomous examples to one- or two-person vessels operating for a few hours, to vessels which can remain submerged for 6 months such as the  Russian  Typhoon class  Ã¢â‚¬â€œ the biggest submarines ever built and in use. Submarines can work at greater depths than are survivable or practical for human  divers.Modern deep diving submarines are derived from the  bathyscaphe, which in turn was an evolution of the  diving bell. History†¦ The first submersible of which we have reliable information on its construction was built in 1620 by  Cornelius Drebbel, a  Dutchman  in the service of  James I of England. It was created to the standards of the design outlined by English mathematician  William Bourne. It was propelled by means of oars. The precise nature of the submarine type is a matter of some controversy; some claim that it was merely a bell towed by a boat. Two improved types were tested in the  Thames  between 1620 an d 1624.In 2002 a two-person version of Bourne's design was built for the  BBC  TV programme  Building the Impossible  by  Mark Edwards, and successfully rowed under water at  Dorney Lake,  Eton. Though the first submersible vehicles were tools for exploring under water, it did not take long for inventors to recognize their military potential. The strategic advantages of submarines were set out by Bishop  John Wilkins  of  Chester, England, in  Mathematicall Magick  in 1648: 1. This private: a man may thus go to any coast in the world invisibly, without discovery or prevented in his journey. 2.This safe, from the uncertainty of Tides, and the violence of Tempests, which do never move the sea above five or six paces deep. From Pirates and Robbers which do so infest other voyages; from ice and great frost, which do so much endanger the passages towards the Poles. 3. It may be of great advantages against a Navy of enemies, who by this may be undermined in the wat er and blown up. 4. It may be of special use for the relief of any place besieged by water, to convey unto them invisible supplies; and so likewise for the surprisal of any place that is accessible by water. 5.It may be of unspeakable benefit for submarine experiment How it work†¦ The adaptations and inventions that allow sailors to not only fight a battle, but also live for months or even years underwater are some of the most brilliant developments in military history. In this article, you will see how a submarine dives and surfaces in the water, how life support is maintained, how the submarine gets its power, how a submarine finds its way in the deep ocean and how submarines might be rescued. Ultrasound scanning device†¦ Ultrasound  is a cyclic  sound  pressure wave with a  frequency  greater than the upper limit of the human  hearing range.Ultrasound is thus not separated from â€Å"normal† (audible) sound based on differences in physical properties, only the fact that humans cannot hear it. Although this limit varies from person to person, it is approximately 20  kilohertz  (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20  kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasonic imaging (sonography) is used in human and veterinary medicine. In non-destructive testing of products and structures, ultrasound is used to detect invisible flaws.Industrially, ultrasound is used for cleaning and for mixing, and to accelerate chemical processes. Organisms such as bats and porpoises use ultrasound for locating prey and obstacles. Ultrasonics  is the application of  ultrasound. Ultrasound can be used for imaging, detection, measurement, and cleaning. At higher power levels ultrasonics are useful for changing the chemical  . History †¦ Acoustics, the science of sound, starts as far b ack as  Pythagoras  in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Sir  Francis Galton  constructed  a whistle  producing ultrasound in 1893.The first technological application of ultrasound was an attempt to detect icebergs by  Paul Langevin  in 1917. The  piezoelectric effect  discovered by Jacques and Pierre Curie in 1880 was useful in transducers to generate and detect ultrasonic waves in air and water. [2]  Echolocation  in bats was discovered byLazzaro Spallanzani  in 1794, when he demonstrated that bats hunted and navigated by inaudible sound and not vision. How it works†¦ There are many reasons to get an ultrasound. Perhaps you're pregnant, and your obstetrician wants you to have an ultrasound to check on the developing baby or determine the due date.Maybe you're having problems with blood  circulation in a limb or your heart, and your doctor has requested a Doppler ultrasound to look at the blood flo w. Ultrasound has been a popular medical imaging technique for many years. Ultrasound  or  ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by  submarines. In this article, we'll look at how ultrasound works, what type of ultrasound techniques are vailable and what each technique can be used for. Magnifying glass†¦ A  magnifying glass  (called a  hand lens  in laboratory contexts) is a  convex lens  that is used to produce a  magnified  image  of an object. The  lens  is usually mounted in a frame with a handle (see image). A  sheet magnifier  consists of many very narrow concentric ring-shaped lenses, such that the combination acts as a single lens but is much thinner. This arrangement is known as aFresnel lens. The magnifying glass is an icon of  detective fiction, particularly that of  S herlock Holmes. History †¦The earliest evidence of â€Å"a magnifying device, a convex lens forming a magnified image† was Aristophanes's â€Å"lens†, from 424 BC, a glass globe filled with water. (Seneca  wrote that it could be used to read letters â€Å"no matter how small or dim†). [1]  Roger Bacon  described the properties of a magnifying glass in 13th-century  England. Eyeglasses  were developed in 13th-century  Italy. How it works†¦ The  magnification  of a magnifying glass depends upon where it is placed between the user's eye and the object being viewed, and the total distance between them.The  magnifying power  is equivalent to  angular magnification  (this should not be confused with  optical power, which is a different quantity). The magnifying power is the ratio of the sizes of the images formed on the user's retina with and without the lens. [3]  For the â€Å"without† case, it is typically assumed that t he user would bring the object as close to the eye as possible without it becoming blurry. This point, known as the  near point,  varies with age. In a young child it can be as close as 5  cm, while in an elderly person it may be as far as one or two metres.Magnifiers are typically characterized using a â€Å"standard† value of 0. 25  m. The highest magnifying power is obtained by putting the lens very close to the eye and moving the eye and the lens together to obtain the best  focus. The object will then typically also be close to the lens. Sense of hearing†¦ Hearing,  auditory perception, or  audition  is the ability to perceive  sound  by detectingvibrations,  changes in the pressure of the surrounding medium through time, through an organ such as the  ear. Sound may be heard through  solid,  liquid, or  gaseous  matter. It is one of the traditional five  senses.The inability to hear is called  deafness. In humans and other vertebr ates, hearing is performed primarily by the  auditory system: vibrations are detected by the  ear  and transduced into nerve impulses that are perceived by the  brain  (primarily in the  temporal lobe). Like  touch, audition requires sensitivity to the movement of molecules in the world outside the organism. Both hearing and touch are types of mechanosensation. Stethoscope †¦ The  stethoscope  is an acoustic  medical  device for  auscultation, or listening to the internal sounds of an animal or human body.It is often used to listen to lung and  heart sounds. It is also used to listen to  intestines  and blood flow in  arteries  and  veins. In combination with asphygmomanometer, it is commonly used for measurements of  blood pressure. Less commonly, â€Å"mechanic's stethoscopes† are used to listen to internal sounds made by machines, such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal part s. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other small-scale acoustic monitoring tasks.A stethoscope that intensifies auscultatory sounds is called  phonendoscope. History†¦ The stethoscope was invented in  France  in 1816 by  Rene Laennec  at the  Necker-Enfants Malades Hospital  in  Paris. [1]  It consisted of a wooden tube and was monaural. His device was similar to the common  ear trumpet, a historical form of hearing aid; indeed, his invention was almost indistinguishable in structure and function from the trumpet, which was commonly called a â€Å"microphone†. The first flexible stethoscope of any sort may have been a binaural instrument with articulated joints not very clearly described in 1829. 2]  In 1840,Golding Bird  described a stethoscope he had been using with a flexible tube. Bird was the first to publish a description of such a stethoscope but he noted in his paper the prior exis tence of an earlier design (which he thought was of little utility) which he described as the snake ear trumpet. Bird's stethoscope had a single earpiece. [3]  In 1851, Irish physician Arthur Leared invented a binaural stethoscope, and in 1852 George Cammann perfected the design of the instrument for commercial production, which has become the standard ever since.Cammann also wrote a major treatise on diagnosis by auscultation, which the refined binaural stethoscope made possible. By 1873, there were descriptions of a differential stethoscope that could connect to slightly different locations to create a slight stereo effect, though this did not become a standard tool in clinical practice. The medical historian  Jacalyn Duffin  has argued that the invention of the stethoscope marked a major step in the redefinition of disease from being a bundle of symptoms, to the current sense of a disease as a problem with an anatomical system even if there are no noticeable symptoms.This r e-conceptualiization occurred in part, Duffin argues, because prior to the stethoscopes, there were no non-lethal instruments for exploring internal anatomy. [4] Rappaport and Sprague designed a new stethoscope in the 1940s, which became the standard by which other stethoscopes are measured, consisting of two sides, one of which is used for the respiratory system, the other for the cardiovascular system. The Rappaport-Sprague was later made by  Hewlett-Packard. HP's medical products division was spun off as part of Agilent Technologies, Inc. , where it became Agilent Healthcare.Agilent Healthcare was purchased byPhilips  which became Philips Medical Systems, before the walnut-boxed, $300, original Rappaport-Sprague stethoscope was finally abandoned ca. 2004, along with Philips' brand (manufactured by Andromed, of Montreal, Canada) electronic stethoscope model. The Rappaport-Sprague model stethoscope was heavy and short (18–24  in (46–61  cm)) with an antiquated appearance recognizable by their two large independent latex rubber tubes connecting an exposed-leaf-spring-joined-pair of opposing â€Å"f†-shaped chrome-plated brass binaural ear tubes with a dual-head chest piece.How to use†¦ * Clean off the earpieces before placing the stethoscope into your ears, especially if others share it or you seldom use it. In the hospital, earpieces are wiped with alcohol prep swabs. * Hold the chest piece between your palms to warm it before placing it on a person's chest. Thirty seconds is usually long enough to remove the chill. * Place the stethoscope into your ears. * Hold the chest piece in your hand. With the other hand, tap a finger against the chest piece and listen. Many stethoscopes have reversible heads, which can be incompletely swiveled and block sound. Grip the chest piece between your middle and index fingers to provide firm contact with the skin. * To minimize extraneous noises, avoid touching or rubbing the tubing or chest piece against clothing, bedcovers or hair. * Place the chest piece onto the part of the body you want to listen to. For the heart, this is a few inches above the left nipple. You should hear a steady â€Å"lub dub. † This is known as the apical pulse. * Store your stethoscope so that the tubing isn't kinked when you put it away. In hospitals, when stethoscopes are not being used, they're generally hung by their earpieces so that the tubing can dangle freely.Loudhailer†¦ A  megaphone,  speaking-trumpet,  bullhorn,  blowhorn, or  loud hailer  is a portable, usually hand-held, cone-shaped  acoustic horn  used to  amplify  a person’s voice or othersounds  and direct it in a given direction. The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. The megaphone increases the volume of sound by increasing the  acoustic impedance  seen by the  vocal cords,  matching  the impedance of the vocal cords to the air, so that more sound power is radiated.It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because thefrequency response  of the megaphone is greater at higher sound  frequencies. Since the 1970s the voice-powered  acoustic megaphone  described above has been replaced by theelectric megaphone, which uses electric power to  amplify  the voice. History†¦ The initial inventor of the speaking trumpet is a subject of historical controversy, as both  Samuel Morland  and  Athanasius Kircher  lay claim to the device.Morland, in a work published in 1655, wrote about his experimentation with different horns and his most successful variant. This loudest horn was made of over 20 feet of copper and could supposedly project vocalizations as far as a mile and a half. [1] Twenty years earlier, Kircher described a device that could b e used for both broadcasting on one end and â€Å"overhearing† on the other. His coiled horn would be wedged into the side of a building, connecting a speaker or listener inside with the surrounding environment.Morland favored a straight, tube-shaped speaking device, where an initial sound would reverberate in waves through the instrument and gradually become louder. Kircher’s horn, on the other hand, utilized a â€Å"cochleate† design, where the horn was twisted and coiled, unlike Morland’s design. A later,  papier-mache  trumpet of special design was the Sengerphone. [2] The term ‘megaphone’ was first associated with  Thomas Edison’s instrument 200 years later. In 1878, Edison developed a device similar to the speaking trumpet in hopes of benefiting the deaf and hard of hearing.His variation included three separate funnels lined up in a row. The two outer funnels, which were six feet and eight inches long, were made of paper an d connected to a tube inserted in each ear. The middle funnel was similar to Morland’s speaking trumpet, but had a larger slot to insert a user’s mouth. [3] With Edison’s megaphone, a low whisper could be heard a thousand feet away, while a normal tone of voice could be heard roughly two miles away. On the listening end, the receiver could hear a low whisper at a thousand feet away. However the apparatus was much too large to be portable, limiting its use.George Prescott wrote: â€Å"The principal drawback at present is the large size of the apparatus. † Since the 1960s acoustic megaphones have generally been replaced by electric versions  (below), although the cheap, light, rugged acoustic megaphone is still used in a few venues, like cheering at sporting events,  cheerleading, and by  lifeguards  at pools and beaches where the moisture could damage the electronics of electric megaphones. How to use†¦ * Hold the megaphone several inches from your mouth with the small end toward you and the large end away from you. * Point the large end of the megaphone toward the crowd you wish to exhort. Speak loudly or shout into the small end. * Wait for the crowd's response, then repeat Step 3 as necessary. Sonar†¦ Sonar  (originally an  acronym  for  Sound  Navigation  And  Ranging) is a technique that uses  sound  propagation (usually underwater, as in  submarine navigation) to  navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Two types of technology share the name â€Å"sonar†:  passive  sonar is essentially listening for the sound made by vessels;  active  sonar is emitting pulses of sounds and listening for echoes.Sonar may be used as a means of  acoustic location  and of measurement of the echo characteristics of â€Å"targets† in the water. Acoustic location in air was used before the introduction of  radar. Sonar may also be used in air for robot navigation, and  SODAR  (an upward looking in-air sonar) is used for atmospheric investigations. The term  sonar  is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as  underwater acoustics  orhydroacoustics.History†¦ Although some animals (dolphins and bats) have used sound for communication and object detection for millions of years, use by humans in the water is initially recorded by  Leonardo Da Vinci  in 1490: a tube inserted into the water was said to be used to detect vessels by placing an ear to the tube. [1] In the 19th century an underwater bell was used as an ancillary to  lighthouses  to provide warning of hazards. The use of sound to ‘echo locate' underwater in the same way as  bats  use sound for aerial navigation seems to have been p rompted by the  Titanic  disaster of 1912.The world's first  patent  for an underwater echo ranging device was filed at the British  Patent Office  by English meteorologist  Lewis Richardson  a month after the sinking of the Titanic,[2]  and a German physicist  Alexander Behm  obtained a patent for an echo sounder in 1913. The Canadian engineer  Reginald Fessenden, while working for the Submarine Signal Company in Boston, built an experimental system beginning in 1912, a system later tested in Boston Harbor, and finally in 1914 from the U. S. Revenue (now Coast Guard) Cutter Miami on the  Grand Banks  off  Newfoundland  Canada. 2][3]  In that test, Fessenden demonstrated depth sounding, underwater communications (Morse Code) and echo ranging (detecting an iceberg at two miles (3  km) range). [4][5]  The so-called  Fessenden  oscillator, at ca. 500  Hz frequency, was unable to determine the bearing of the berg due to the 3 metre wavelength and the small dimension of the transducer's radiating face (less than 1 metre in diameter). The ten  Montreal-built  British H class submarines  launched in 1915 were equipped with aFessenden oscillator. [6] During  World War I  the need to detect  submarines  prompted more research into the use of sound.The British made early use of underwater hydrophones, while the French physicist  Paul Langevin, working with a Russian immigrant electrical engineer,  Constantin Chilowski, worked on the development of active sound devices for detecting submarines in 1915 using quartz. Although  piezoelectricand magnetostrictive transducers later superseded the  electrostatic  transducers they used, this work influenced future designs. Lightweight sound-sensitive plastic film and fibre optics have been used for  hydrophones  (acousto-electric transducers for in-water use), while  Terfenol-D  and PMN (lead magnesium niobate) have been developed for projectors.How to u se†¦ * Install the transmitter. You'll usually have a choice between mounting the transmitter beneath the boat, to a trolling motor or atop the interior hull and letting it drop into the water. * Set the fish finding sonar's sensitivity while watching the display. When the sensitivity is too high, there will be static-like patterns on the display. If the sensitivity is too low, not even the bottom of the body of the water will appear on screen. * 3 * Determine the depth of the body of water. This will be a numeric value on the fish finder sonar system's display.This is important in helping you to determine how much fishing line to feed out from your pole. * Get accustomed to the display's representation of the body of water. The bottom will appear as a jagged, solid line near the bottom of your display. The surface of the water appears as a jumbled static-filled horizontal line at the top of your fish finder sonar system's display. * Learn to identify patterns on your display t hat are brush piles if you're fishing on a lake. Brush piles appear as blobs resting on the lake bottom.Fish such as bass hide out in brush piles, so consider fishing near these echoes. * Learn how to identify fish on your fish finder sonar system display with the fish symbols turned off. With the symbols turned off, fish appear as short curved lines above the bottom of the body of water. Adjust the fish finder sonar's noise filter if there are lines in your display that look like random static. * Remember what the fish finder sonar display was indicating when you catch a fish. This will help you to learn how to use your system to catch more fish later if you keep in mind what to look for.
