Puberty Blues Essay

The TV show I have chosen to talk to you about today is Puberty Blues. It is aired at 8:30pm, Wednesday on channel 10. It doesn’t have a specific genre, but more like a mixture. I would classify it as a teen drama. Puberty Blues doesnt work in plot twists but offers a suprising reality. The best part about the TV drama for me is how we get a glimpse into the life of a 1970’s teenager. Puberty Blues is set in Cronulla, Sydney, in the late 1970’s. Majority of the time, Debbie and Sue’s houses are used, but the ‘greenhill gang’ are also featured hanging around by the beach. Puberty Blues tells the story Debbie Vickers and Sue Knights. They are both very clever but somewhat unpopular high school girls who wants to raise their social standings in order to go out with boys. Through out the episodes we get to know the girls’ parents- Judy and Martin who are closed off and don’t interact with each other much and Pam and Roger who have a far more open relationship. The sixth episode was directed by Glendyn Ivin and written by Fiona Seresis. The main plot is when the ‘greenhill gang’ including Debbie and Sue, get wasted, go driving and flip the car, killing the driver. Any other show would have sent the characters into an instant panic but the writers of Puberty Blues understand that the shock combined with drugs would have caused everyone to burst into disbelieving laughter. The car crash wasn’t the only plot in the episode though. Debbies parents, Judy and Martin, got to couples councilling because Martin has strong feelings for a women at his work. Cheryl, a member of the ‘green hills’ gang, is flirting with her mum’s boyfriend to prove she is more desirable than her mother, who resents. The social issue pressented in the show was definitely driving under the influence. This message is easily interpreted in the car crash scene were the driver and passengers are drunk and stoned. This wasn’t my favourite episode from Puberty Blues but it was still solid like we have come to expect from this series. I would recommend the show to high school students and older as there are some mature themes and sexual references. I love this show because it takes awkward and serious situations and brings out their bright side.

The Significance of Dance in Dancing at Lughnasa

The Significance Of The Use Dance: Focusing On Pages 20 – 23 Brian Freil uses a variety of dance techniques to convey the significance of dance as a projection of universal and primal desires to which everyone is submissive. Each outburst or description of dance involving the characters gives the audience an insight to not only their true personality but also the strain of their current situations. The significance of dance and its effect on the audience is echoed throughout the play through many different circumstances, the positioning of each routine is also very important as it connects with true meaning of the dance, therefore intensifying atmosphere on which it brings. Pages 20 to 23 highlight this greatly as we see all of the sisters dance in unity. Page 20 sees Maggie’s monologue, here the audience become aware of how dance can be beautiful however misunderstood; â€Å"they were just so beautiful together†¦ they should have won† Explained as Maggie is describing the pure splendor of Brian and Bernie’s military two-step at a dance competition from when they were young. Although this directly does not link directly in the significance throughout the play it strengthens the aspect of a spirited connection between two people through the means of dance. This point is also enhanced with the connection between Chris and Gerry as the audience only become apparent of the sentimental emotions these characters share when she submissively begins to ballroom dance with him, at which point and further in the play all characters especially Chris soften to Gerry giving implication of the true and raw feeling they have for each other represented through their dances. This spiritual characteristic which dance beholds amongst the characters also has connotation of a form of communication that predates conversation and emotion, seeping through all cultures. This is a strong feature to Dancing At Lughnasa as the storyline is based around Freil’s use of juxtaposition of native tribal dancing and localized northern Irish dancing with the use of Father Jack. The use of Father jack; â€Å"losing his mind† on returning from Africa and resorting to African rituals and beliefs bridges strong Irish traditions to the frowned upon peaganism of the Irish mid 1930s. Depending on interpretation you could argue that Freil suggests this bridging of cultures throughout the play to enhance the technique of juxtaposition. An example being in the ironic connection between Jack’s description of an African ceremony shortly followed by the unofficial wedding of Chris and Gerry described also, as a ceremony of an elegant and precise ballroom dance. Also on page 21; â€Å"patterns her face with an instant mask† The stage direction describing Maggie’s fanatical dance and how she stripes her cheeks with flour. This gives suggestion of connotation, which could be implying the link between typical tribal face paint used for rituals and dances in native Africa and Maggie’s flour â€Å"mask†. In addition this too gives implication of Maggie being ‘out of character’ and acting peaganistic, again, strengthening the thought of dance being a universal and primal desire bridging cultures due to subconscious human nature. The radical and fanatical dancing of the sisters on page 21 is also important in understanding how Freil communicates the characters personalities and thoughts to the audience in the stage directions of each dance. Freil uses the ‘Marconi‘ as a dramatic device to plunge the scene into dance with the slow introduction of sound; â€Å" until the sound has established itself† this could show how the beat and rhythm of the music is actually the subconscious of the characters. However, another interpretation could be that the slow introduction is the metaphorical gradual dispatch from reality into a fantasy of dance coated by repressed desire and latent passion. This would explain how Maggie’s â€Å"features become animated by a look of defiance† as it is a result of the realization of her repression which has grew from since she was young that manifests itself with defiance. It would too explain how as each character becomes submissive to the rhythm, the beat becomes more frantic and uncomfortably loud because each of the sisters is now projecting suppressed emotions with a feeling of force and urgency. This shows how the stage directions also give implication to the character’s psychological state. Other characters such as Rose, who follows Maggie’s chants and calls and is the second to â€Å"leap† into dance, this could be an indication of Rose’s suggestive character and how she yielding to those offering attention such as Danny Bradley, her supposed lover. Rose is then followed by Agnes who is described to dance the most â€Å"gracefully and sensuously† out of the sisters which could represent her soft, and delicate personality highlighted through her caring actions towards Rose, and the household keeping earlier in the play. However the most significant character’s performance in this dance is Kate, the audience have been subjected to her objection to the festival at Lughnasa and peaganistic dance traditions yet as the final sister to join we see Kate preform a complex dance; â€Å"alone, totally concentrated, totally private† and although the other sisters are chanting and screaming together, Kate is in silence. This outburst is one of the most fundamental moments in the play as a whole, as the audience are taken back by Kate’s obscure and out of character reaction to the rhythm. Being the last to plunge into dance and the first to stop shows how Kate is conceited and is against the force which dance holds, however her ominous actions are clearly full of true of emotion which represents her true personality one of passion and complete feeling. The intensity and isolated feel of her performance is a representation of the distance between her and her sisters caused by the strain of keeping the family together, which is ironically, obviously falling apart. At the end of the stage directions on page 22, the audience are aware of the significance of Freil’s use of dance. The brutality and grotesque atmosphere of the dance is the projection of the unstable state the family is in, as each sister is under independent and personal strains. Which appeals to the audiences’ emotional and psycho-analytic understanding therefore creating two layers within Friel’s production. By using this form of communication frequently throughout the play the audience can therefore connect with the characters and relate to their created personalities to prehaps, feelings of their own. Dance, in the production of Dancing at Lughnasa is consequently not only a connective device between the audience and the characters as it is a projection of primal desires, but also a representation of repressed feeling and emotion of which the characters cannot express verbally.

Strategic Situation Analysis for Developing Critical Thinking Skills - Essay - 8

Strategic Situation Analysis for Developing Critical Thinking Skills - Matching Dell - Essay Example The approach towards analyzing a situation is based on productive and critical mindset and involves several steps in its execution. One of the most important steps in SSAS is to investigate the underlying strategy of a situation and find out how that strategy influences the outcomes, productivity, and results of the study at hand. This constitutes the third step in the SSAS approach. The pertinent case study is dealing with the functioning of the Dell computer company, and its comparison with its rival companies. This involves examining the management and strategies of the Dell Corporation and matching it with its rival corporations. Towards the mid-‘90s, the advent of personalized computers had taken over the market, and more and more customers were finding new reasons to obtain their own computers. This meant that computers were no longer limited to big corporations and businesses, but were becoming a household commodity. This gave companies like IBM and Apple, which were previously manufacturing mainframe machines, to produce PCs and tap the huge profits in this sector. Initially, IBM, the leading company in computer hardware, took over the market by manufacturing PCs and loading them with software developed mainly by Microsoft. Their contract with Microsoft proved fruitful and they were soon the leaders in the market. Other companies like Compaq, HP (Hewlett-Packard) and Gateway followed suit. They all focused on developing the hardware and contracting with software companies like Microsoft or Apple to provide them with the operational programs, and their main customers were big and medium-sized corpor ate organizations. Dell was another such company dealing with the manufacturing of PCs.However,  their method of working was radically different  from the other companies,  and it was so successful  that it gave  them a huge edge of advantage that  soon earned them  the leading position in the market.

Offshoring Essay Example | Topics and Well Written Essays - 1250 words

Offshoring - Essay Example The work of Robert Reich focuses on different reasons of growing poor and rich discriminations in the US. This paper identifies various reasons and discuses their further reasons and consequences. It then tries to evaluate some policies which are needed to prevent the unexpected situation of income inequality. And the last paper, Roger LeRoy Miller, Daniel K. Benjamin and Douglass Cecil Northfocuses on the various facts and figures of prevalence of poverty in the US and suggests several policies which are needed to be implemented by the government to restrict the situation. The problem of low income and income inequality mainly arises from offshoring and calls for appropriate policies from the side of the government Blinder: The main purpose of his work is to relate the concept of offshoring with the US labor market and to understand its problems and possible solutions and effects. The key question of this paper is how to prepare the future labor force of US in the face of rapid offs horing of US companies. Over the last few years the demand for labour has shifted from technologically low skilled, less educated people to high skilled and well educated people. This led to income inequalities in the US.Hence, policies were needed to be applied. In the 1990s, the United State Congress has used the policy of raising the minimum wage and has increased the Earned Income Tax Credit (Blinder, 2009, p. 9). With the combination of the tight labour market, these policies have raised disposable income of the average workers and have improved their living conditions. But the basic assumption behind this success was that there was not any labour migration during this time of policy evaluation. The major future challenge for the US is â€Å"offshoring†. In the US, service sector offshoring has not been that much significantly higher; only 1% of the total services jobs have been offshored so far (Blinder, 2009, p. 10). There can be three basic reasons for more increment in the offshoring of services jobs. First, there are more absolute numbers of services jobs compared to that of manufacturing jobs. Second, technological advancements are more related with the growth of services jobs. Hence, recent developments in technologies have caused this difference in the growth paths. And finally, the labor market of India and China are more consistent with the technologies related to services jobs.The author has distinguished between two types of facts that are responsible for offshoring – personal and impersonal reasons. This is the most important information that the author has pointed out and this is the key idea of the whole paper. In this context the author suggested few points that are needed to be considered while preparing the future labor force of the US- putting more emphasis on education of children, focusing on one link (like technology) at a time and differentiating between novel differences with the traditional differences in jobs.One of the possible implications of these policies is that there would be huge income differences, not in terms of educational level, but also in terms of the skills that workers have. But in the future education will not become constrained. For public jobs, increases in the salary scales can work well in this regard. Again, some o the jobs are lacking proper training

Logistics management Essay Example | Topics and Well Written Essays - 2500 words

Logistics management - Essay Example The rapid growth of technology has significantly changed the social, economic, and political aspects of life. The immense impact of technological advancements has made enterprises to embrace technologies in ways that enhance their competitive advantage. It has become apparent to enterprises that their survival in the knowledge-based economy greatly depends on how they improve their technological capability. In particular regard to logistics, firms have realized the essence of developing adequate methodologies so as to successfully adopt new technologies in this field, as well as integrating logistics into their corporate strategy for gaining more competitive advantage (Waters, 2007, p. 76). Since the conception of computerization, Information, Communication and Technology (ICT) have assumed supporting role for functions of the organizations. In recent years, logistics has changed with the growth and adoption in the use of ICT systems such as GIS, Warehouse Management System, Transpor t Management System, and GPS among others. The use of these ICT systems has considerably improved the way companies manage their supply chains. Major ICT systems have impacted on each of the logistics component (Sauvage, 2003, p. 237). It is against this background that this paper will seek to evaluate the key components of Logistics Management and discuss the major ICT systems in each component of logistics. In addition, the paper will provide a critical analysis of benefits and challenges in adopting and applying the technology in logistics. Components of Logistics Management It is important to point out that components of logistics management are aimed at achieving the following: satisfying customers’ needs; product selection; monitoring quality of services and goods; dealing with logistics information accordingly; inventory management; and forecasting and procurement (Grant, 2006, p. 24). Mainly, there are eight components of logistics management. i) Customer Order Proces sing This component is designed to facilitate customer satisfaction. It involves flow of the following actions: filling of the order form; making decisions on the specifications of particular product; making decision on the quality check list of the product; deciding on the delivery schedule and deciding on the delivery location of the goods. The flow of actions is highly customer-focused and aims at meeting all the requirements of the customer. This component takes into consideration several important factors. Firstly, it takes into account the cost of order processing and ensures that this type of cost is appropriate for both the customer and the logistic firm. The second factor that is considered is whether the logistic firm has the capacity to produce the required component (Langley, 2006, p. 42). The third factor that is considered under this component is the detailed list of specifications; the company should ensure that the component being processed for customer has met all t he specifications required by the customer. The component of customer order processing has adopted and used ICT systems to make its operations effective and efficient. The major ICT systems that has been adopted and used in this component are Electronic Data Interchange, Web Portal, and E-ERP. Electronic Data Interchange (EDI) is an ICT system that facilitates structured transmission of data by electronic means between organizations (Sauvage, 2003, p. 240). Logistics companies have used

The Microsoft Dominance Essay Example | Topics and Well Written Essays - 1000 words

The Microsoft Dominance - Essay Example The paper tries to analyse the economic position of Microsoft and understand why they have been able to retain themselves as a monopoly in the market. Let us start with the definition of monopoly and then analyse the same definition with respect to the share controlled by Microsoft in the market. â€Å"A situation in which a single company or group owns all or nearly all of the market for a given type of product or service. By definition, monopoly is characterized by an absence of competition, which often results in high prices and inferior products.† Monopoly Definition." Investopedia.com - Your Source For Investing Education Inferring from the above definition, a monopoly is a state of market where one company controls the market with a tight management in place and holding a dominant share where it can dictate the prices and the supply of the product to the market and therefore would exercise a position of power in the respective market. Microsoft enjoyed such dominance in the OS market for computers for two decades and still holds that position due to the free availability of its products in the market. â€Å"Microsoft accounts for 90-95% of microcomputer operating systems, and it is the de facto standard for computer applications. It is obvious that it is dominating the market. However, one could argue that its market power is gained from the consumer choices†¦its legitimacy rests upon consumers who willingly, and in a market with alternative resources and options, chose to buy Microsoft products.† InfoTech & Public Policy  » Blog Archive  » Is Microsoft a â€Å"monopoly† Based on Standard Economic Theory?" The economic theory behind the dominance of Microsoft has been monopolizing the market and creating products which the competitors failed to innovate in. Microsoft was able to take the Windows to a level where there was no competition at all from the rest of the players in the market. Let is have a look at the OS market to understand why Microsoft was so successful in monopolizing the market for such a long time. At the time when Windows was launched, there were only two players in the market for OS. One was the Macintosh designed by Apple, and the other was windows designed by Microsoft. The precarious thing about Apple was that they only created their OS for their own machines and did not outsource the product to other manufacturers waiting in line to produce the Macintosh. Since Apple did not sell their Macintosh OS to third parties, the manufacturers were left with only one option, and that was to buy the OS from Microsoft, the Windows based application. Since Macintosh was more expensive than Windows and did not give an opportunity to oither manufacturers in the market to use their OS, the Windows grew in popularity. The OS was much more cheaper to use and to apply on machines, and since was an open software there were more applications designed for it than they were for the Macintosh. â€Å"eco nomists maintain that a monopoly does not exist simply because there is only one provider of a good or service. For example, in the Microsoft case, the Windows operating system is enormously popular, but the potential for a competing firm to provide a similar product exists. In fact, Macintosh is a small but important competitor in the computer and operating system market. Linux has also emerged in recent months as a viable alternative to Microsoft Windows† South-Western: Is Microsoft A Monopoly?" Web. 27 Nov. 2011. Whether the Monopoly is in the Public Interest: There are two sides to the argument whether the monopoly has been in the public interest or not. The paper address both the points of contention and then understand why one arguments

Infection Control practices in Dentistry Research Paper

Infection Control practices in Dentistry - Research Paper Example The paper tells that dentistry is one of the most important and widely studied disciplines in medicine. It refers to the study, examination, prevention, diagnosis, and treatment of disorders, conditions, and diseases related to the oral cavity. This pertains to teeth in particular, along with the conditions present in the face and jaws (maxillofacial) area to some extent. Though the field of dentistry is also related to the cosmesis, it is usually considered entirely as a branch of medicine. In order to stay healthy in every aspect, dentistry is considered significantly important. A dental team carried out the dental treatment, and it usually comprises of dental auxiliaries (dental hygienists, dental therapists, dental assistants, and dental technicians) and dentists. Majority of the dentists render their services in primary care or private practices, along with some others working in secondary care (hospitals), and other institutions such as armed forces bases, prison etc. The histo ry of dentistry dates back to 7000 BC when it was practiced in the Indus Valley Civilization. Thus, dentistry is thought to be equally ancient as the history of civilization and humanity is. Slovenia was the place that showed the evidence of the earliest dental filling, formed from the beeswax more than 6500 years back. Then, in the 17th century, the Edwin Smith Papyrus wrote a manuscript, which reflected those written in 3000 BC detailing the treatment of various dental diseases. The Code of Hammurabi had referenced twice the dental extraction relating it to the punishment. The science of advanced dentistry finally took roots and developed between the years 1650 and 1800 by Pierre Fauchard, a French surgeon, who also got popular as the "father of modern dentistry".

Article Critique Essay Example | Topics and Well Written Essays - 750 words - 3

Article Critique - Essay Example The Great Conversation is a means to involve community in the educational process. It consists of two different tracks: informal and formal. Vollmer cites the remarkable progress in relations achieved using the Great Conversation in Colorado, Wisconsin, and Kentucky. However, he does not give the details of these three situations. He merely makes a few vague comments about the schools systems and their relationship to the public. One of the major drawbacks of the article is that Vollmer largely ignores the informal track of the Great Conversation. While he admits that the focus of his article is the formal track, he devotes only three short paragraphs to the informal track. If an approach to public relations involves two main tracks, an article should address both equally in order to create a balanced view. Vollmer seems to bias the article toward the formal track. Vollmer uses the last half of his article to explaining the formal track of the Great Conversation. ... The most obvious errors in the article are two. Firstly, the major obstacle to creating public relations programs between schools and the community is a lack of time on the part of both parties. Vollmer never addresses how the Great Conversation solves this fundamental problem. If anything, the article points out that public relations programs are almost impossible to create due to the time commitment needed on both sides. Secondly, and most importantly, author Jamie Vollmer is president of Vollmer, Inc., a public education advocacy firm focusing on increasing community involvement in education. Clearly, he has bias in relation to the subject about which he is writing. His firm exists to help schools create and maintain public relations programs. Additionally, the firm sells certain approaches to public relations to school districts. There can be little doubt that Vollmer sells a package that includes the Great Conversation. Finally, as Vollmer is president of the firm, he is respons ible for the financial health of the organization. This fact means that he must sell his firm’s product, and this article is an advertisement for his firm. I feel that public relations programs are important for school success to a limited degree. The success of a school can be impacted by the amount of involvement from the community. However, in my experience, the most important involvement is individual, i.e. between parents and teachers. The intrusion of business into schools is detrimental as it affects the operation and goals of the school. Also, the general public does not understand the workings of the educational system and often public relations programs spend the majority of their time

How does the overall diagnostic accuracy of computed tomography Article

How does the overall diagnostic accuracy of computed tomography enterography compare with magnetic resonance enterography for assessing disease activity in small bowel Crohn's disease - Article Example CTE is also similar in accuracy to the MRE. Both techniques are highly accurate in identity of abscesses and fistulas (sensitivities and specificities are greater than 0.80). However, MRE should be preferred over CT in young patients because of the absence of radiation. Both CTE and MRE have high accuracy in the assessment of suspected, as well as, established CD and are reliable in measuring complications and disease severity and give the probability of monitoring disease progress. Studies describe Crohn disease as a chronic inflammatory disease associated with the gastrointestinal tract and characterized by segmental and transmural swelling of the walls of the intestines. Its prevalence is increasing while its etiology is not known, though evidence suggests that genetic predisposition in combination with the abnormal interaction of the gut and enteric microbes is likely to play a role in its pathogenesis.1, 3,9,11 Studies investigating the pathology of CD have established that Crohn’s disease present with insidious or abrupt onset of diarrhoea and abdominal pain; this is accompanied by weight loss and fever. Bowel ulceration may cause fistulas and extramural abscesses. Pathologic findings of Crohn disease in the alimentary canal encompass deep ulcers, transmural granulomatous inflammation. 2, 3, 5 This may progress to fistulae and sinus tracts, discontinuous involvement with areas between diseased segments and structures that can result in intestinal o bstruction. Extra-intestinal manifestations include: cholelithiasis, arthritis, dermatologic abnormalities, growth retardation in children and ocular manifestations. Evaluation of inflammatory lesions in the intestines is crucial for managing CD patients, identification of disease extension and location during diagnosis is required in establishing a good management plan. These techniques are also accepted for the detection of all

MySpace and Facebook Essay Example for Free

MySpace and Facebook Essay I think that stalking is possibly one of the scariest forms of abuse there is. Both men and women are capable of stalking but I think that in most cases it is a male stalking a female. There are many reasons why one person stalks another. I believe the most common reason is because of anger and humiliation. When one person breaks off a relationship with another it often causes conflicting feelings which may turn a person into a desperate stalker. I believe that the longer and more intimate a relationship was the higher chance for stalking and dangerous behavior. I think another big reason why a person will turn into a stalker is because they simply cannot accept that their former partner has moved on and is dating other people. I agree that cyber stalking has become a problem and I think cyber stalking will continue to increase since so many people use computers. The case of the 13 year old girl who committed suicide because of cyber stalking is sad and shocking. I know from experience that teenagers can be quite cruel to one another but this young girl experienced extreme bullying by an adult who should have known better. I strongly believe that the ultimate responsibility for the safety of children on the computer falls to the parents. Parents are responsible for ensuring the safety of their children at all times – including who they talk to and what sites they visit on the internet. In this case it was the parent doing the harassing and terrorizing which is what makes this case so nauseating. Social sites such as MySpace and Facebook make it very easy for teenagers to form cyber relationships with one another. This isn’t necessarily a bad thing as long as parents supervise and children behave appropriately. However, I think cyber stalking is going to continue to increase since so many teenagers use these types of sites and their parents have no idea who they talk to or what they talk about. I think the case of the 13 year old girl who killed herself should open the eyes of parents so that they can prevent something tragic like this from happening again.

Marketing creating hedonistic consumers

Marketing creating hedonistic consumers Within the academic and the marketing world it is recognised that there is debate on what role the discipline of marketing plays in the creation of hedonistic consumers. The most extreme debates come from those who hold opposing views. This paper will look at some of these polarised views and perspectives in regard to consumer behaviour and will argue that marketing has not created hedonistic consumers that such a stance does not allow for the complexities of human behaviour and motivations and does not take account of the dynamic nature of consumer society. We agree there are associations and parallels in the development of both consumerism and marketing but there is no evidence to prove cause and effect. According to Armstrong et al (2009, p8), wants are the form human needs take as they are shaped by culture and individual personality. Wants are shaped by ones society. Therefore, consumer wants are not shaped solely by marketers. Conversely, Solomon et al (2006, p21) highlight that marketing is often criticised for employing techniques that convince consumers that they need many material goods and that they will be unhappy and inferior if they do not have these necessities. Do marketers give people what they want, or do they tell us what we ought to want? Marketing is often assumed to be responsible for our consumer society and its hedonistic approach to consumption, and as a consequence undermines other cultural values by promoting a materialistic stance. For many commentators it is the dark side of marketing and worthy of review as it diminishes the marketing professions reputation. 1.1 Definitions Before defining hedonistic consumption, it is useful to define the philosophy of hedonism. This is a school of thought that says the pursuit of pleasure is the most important thing in life, that views man as being motivated by the desire for sensual pleasures therefore this quest for the good life becomes mans driving force. The hedonistic consumer can be viewed as pleasure loving or self indulgent person with a high level of consumption, more preoccupied with their own material goals than thinking of the wider view of society. Hedonistic consumption is the multi-sensory, fantasy and emotional aspects of consumers interactions with products. (Soloman, 2006, p39). This element of fantasy is crucial to this theory as it is the imagined pleasure that attracts the consumer. OShaughnessy and OShaughnessy describe this as the general agreement that consumer pleasure lies not so much in the physical sense as in the total emotional experience. So the pleasure and happiness is real even though the experience can be imagined in the consumers brain. From a negative point of view Migone, 2006 views it as a highly wasteful and discrimatory pattern of consumption that predominates in current capitalist models. Hedonism and Fantasy The role of fantasy in hedonic consumption is key and whilst academics view it from different perspectives they do agree that it plays a pivotal role in pleasure seeking. Gabriel and Lang (2006) are of the view that Western consumption many agree is a realm of seduction alluring and glamour. As goods leave the world of production to enter the sphere of display, circulation and consumption, they become objects of fantasy and instruments of pleasure. Whilst Abercrombie states that lives are organised around fantasies and daydreams about consuming; they are hedonists, primarily interested in pleasure, and sensual pleasure at that they are individualists, largely pursuing their own ends and uncaring about others.(Abercrombie, 1994, 44). Campbell (1987) in The Romantic Ethic and the Spirit of Modern Consumerism described the key aspect in the creation of the hedonistic consumer as being one concerned with the power of the imagination, he highlights the differences between what was regarded as the traditional view of hedonism and the modern view. He suggested that traditional version was a hedonism of a multitude of pleasures, of the senses whilst modern hedonism seeks pleasure not in sensation but in emotion accompanying all kinds of experiences. The pleasure lies in the meaning of the experience to the individual. This is the form we are dealing with in postmodern culture. Campbell suggested that the consumer as hedonist must be able to derive pleasure from every item they come into contact with and everything must be orientated to that end. That consumers are in a constant state of unsatisfaction, an ongoing state where we are dreaming about something new however this is linked to the other defining factor of modern hedonism that disillusionment comes from the disappointment when the imagined pleasure are always greater than the actual. When anticipate the enjoyment and pleasure that we will gain when we finally purchase and wear the new phone/watch/car we have been day dreaming about buying, our pleasure is often not as we imagined and is fleeting. We have moved on to dreaming about the next better version and start to feel bad about not having it. Consumerism good or bad? Underpinning the debate on whether marketing has created hedonistic consumers is the view on whether consumerism is a positive or negative force. Some celebrate the rise of the consumer, taking the view that consumerism is the essence of the good life, that a consumer society allows us personal freedom, power and happiness through our ability to choose, acquire, use and enjoy our material objects and experiences. Seen as a sophisticated, mature individual who seeks enjoyment in life: by making choices and exercising freedom. (Gabriel and Lang, 2006, p8). Others are concerned that consumerism is associated with reduced consumer well being, partly in terms of quality of human relationships and levels of happiness. That those focused on materialistic values have lower personal well being and psychological health. (Kasser,2002). Abela (2006) furthers this argument indicating that hedonistic consumerism shows an association between marketing practice and the harms of consumerism may be greater than it is generally believed to be by marketing academics. 3. Claims against Marketing Too much interest in material possessions is the responsibility of marketing? Critics have argued that the marketing system encourages too much interest in material possessions. people are judged by what they own not who they are. (Armstrong et al, 2009 p.552). Critics dont view this as a natural state of mind but one created by marketing. In answer to this claim many marketers would argue that this alleged ability of marketing to create needs is wishful thinking and is overstating marketings scope. In support of this it follows that marketers are most successful when they appeal to existing wants rather than when they attempt to create new ones. Also that people seek information when making important purchases and mostly do not rely on a single source (Gabriel and Lang, 2006). However, todays mania for goods is learnt not instinctive according to Naish, 2002. On a deeper level our wants and values are influenced by many factors including family, peer group, religion, ethnic background and education. If modern society is highly materialistic, these values arise out of socialisation processes that go much deeper than business and mass media could produce alone (Gabriel and Lang, 2006). OShaughnessy and OShaughnessy (2002) argue that accumulation of material possessions is a consequence of wealth. Marketers create artificial needs? According to Solomon et al (2006), some conservative traditionalists are of the view that advertising in particular, contributes to the moral breakdown of society by presenting images of hedonistic pleasure. Conversely, leftists argue that they same misleading promises of material pleasure function to buy off people who would otherwise be revolutionaries working to change the system. OShaughnessy and OShaughnessy (2002) note that wants must be created and that there must be an underlying appetite for the product in the first place. Solomon at al conclude that while marketers do not create artificial needs, they do contribute heavily to the socialization of people in contemporary society and thus to the establishment of the social system of needs. Consequently marketers must take a share of responsibility for the development of society. Marketers promise miracles? Consumers are led to believe that via advertising that products have special properties; they will so special things for them that will transform their lives. Soloman et al argues that the manipulative effect of advertising is often overstated, however does concede that there is little doubt that advertising creates and changes patterns of consumption. They offer the view that the main affect may be that the idea that we are defined by our consumer choices is perpetuated by the advertising medium. The impact of fantasy and imagery in influencing buying OShaughnessy and OShaughnessy (2002) cite Baudrillard (1981) who suggested that due to the new technology of electronic media we now have a world where the distinction between real and images has become blurred and consumers are viewed as non-rational who gravitate to instant gratification. The claim is that the consumer thinks that this is the reality, however according to OShaughnessy and OShaughnessy there is no proof to substantiate the claim. Image saturated environment pressing consumers to buy The sheer insistence and multiplication of marketing messages is evidence to critics of marketing. The sum of the mass effect on consumers pushes them in a hedonistic direction. However consumers are sophisticated and selective, they take notice of the products that attend to them. (OShaughnessy and OShaughnessy,2002). Consumerism and Identity Many cultural forces have been accused of having a role in the creation of hedonistic consumers the marketing of Hollywood and Celebrity culture are named often in the debate. Its is recognised by psychology that our ability to weigh desirability and value is knocked awry if the item is endorsed by a well known face. The part of the brain involved in trust and learning is activated and as a result we feel like we are their acquaintances and we want to be like them. (Naish, 2008). We chose carefully who we copy and why and have evolved to emulate the most successful, maybe why many of us feel compelled to keep up materially with celebrities. Consumption, is it addictive? Lasch (1991) takes a pessimistic view believing that western consumerism, sustained by mass production and celebrated in the mass media, amounts to a mechanism of addiction. Though Migone (2007) concedes that rather than marketing being at the root of this addiction: it is due to technological advances which facilitated large scale production which in turn leads to large scale consumption. Consumerism and loss of Community Naish notes that only modern capitalist countries concentrate on material greed. In pre capitalist societies the highest worths was ascribed to things like family, clan, religion, honour not shiny new objects. This he says relates to our most base instincts which are the need to relate to others and feel part of a community. According to Naish, man has lost his moral framework, sense of community and lifes higher meaning, so that now all that remains is our thirst for possessions and pleasure. That being a hedonistic consumer does not make us happy and has a detrimental effect on our human relationships. Critics have linked this loss to marketings lack of focus on these types of human values. In defence of Marketing Consumerism and Wealth The 80s recognised a triumph for consumerism old moral restraints on consumption (frugality, thrift and guilt) swept aside by an extraordinary, credit lead consumerist boost (Lee, 1997). Gabriel and Lang recall that greed lost some of its pejorative and puritanical connotations, in reference to the 1980s. Consumption and Identity It has been said that consumers take identity from their possessions. Consumption has expanded to fill the vacuum left by the decline of the work ethic. Bauman (1988) also argues that consumption is the new pioneer frontier in which individuals may successfully assert themselves, with no insecurity and not harming others. Shopping is not merely the acquisition of things: it is the buying of identity. (Clammer,1992). This is another view that consumer consumption comes from within. Also the general rise in disrupted families has been linked to new ways of forming identities through goods how negative the effects are depends on the underlying motives. Human Nature Naish believes we are genetically programmed to always want more. In prehistoric times its been discovered that cave dwellers had collections of axe handles, that these were the Jimmy Choos and Ferraris of their time. Important to note that OShaughnessy and OShaughnessy argue that marketing materialism are interdependent and that marketing helps precipitate materialism and materialism in society advances the development of marketing. According to Bauman, (1999) the major contributing factors to hedonistic lifestyle are pervasive insecurity and uncertainty fear of the future and the ecology of the planet; danger- threat of terrorism and wars; decline of family breakdown of traditional institutes such as family as one of the main cultural reference points. It has been argued that marketing creates hedonism by creating wants. This begs the question can wants be created? According to Moore (1994) materialism and hedonism were not invented by consumer marketing; they were there before its advent. Although, it has been widely acknowledged that consumers have latent wants that can be activated, but recognise that they have a great ability to filter information. Marketers often chose hedonistic appeals, but marketing in itself is simply an orientation and a set of tools that are value neutral and can be used to proselytise any perspective. (Cook, 1992). Social commentators have noted that that pursuit of pleasure is mans natural position and it goes against human nature to deprive oneself and that accumulation of material possessions is due to the fact we have the means to indulge our wants. However they agree there is an acknowledged link but no proven cause and effect but this is viewed as marketing being in the role of facilitator not creator. Marketing and Economy Marketers have accused critics of taking the hyper real world of marketing, advertising and dreams too literally. Arguing that freedom of choice is better for consumers and is a fundamental underpinning of our economic system. Stimulus-response model of buyer behaviour This widely accepted model of consumer behaviour illustrates that whilst marketing stimuli are important so are as are culture, politics, economics and technology. These come merge with consumer psychology and the individual consumer characteristics. These are interlinked and conclude with a final selection of a product. This model is illustrative of the fact that marketing stimulus is only part of the consumer behaviour process. (Please refer to appendix 1). The Future Western style consumerism is facing and creating serious threats ecological crisis, climate change, resources shortages and financial uncertainties. There is an increased awareness among academics and consumers of the ecological limits of consumerism and current debate is focused on its sustainability. Consumers are said to dictate production, they fuel innovation, create new social systems, drive modern politics to have the power to save the environment and protect the future of the planet and yet at the same time are seen as weak and malleable creatures, easily manipulated, dependant, passive and foolish. (Gabriel Lang, 2006). It is recognised that there is a need to engage in debate on the containment of the negative aspects of consumerism. At the centre of the debate is the question of social consequences and the role of marketing in creating the consumption culture.. If we suspect that marketing is contributing to the harmful effects of consumerism what are the courses of action marketers should review? Abela (2006) cites Csikszentmihalyis (2000) suggestion that greater transparency about the effects of materialism would help. Recommends marketers undertake studies for emerging groups the non consumerist consumer, anti consumerism groups and should monitor general consumer awareness. So if the consumer is more aware of the consequences they might not choose the path of consumption especially if it leads to unhappiness and dissatisfaction. Increased efforts at consumer education maybe able to correct this and lead to changes in consumer behaviour. One possible area of study is to look at regions not affected yet possibly in eastern cultures. Some believe we are at the point of a fundamental structural change in the nature of consumerism. Others keeping the faith in the market to right itself. Optimists believe technology will provide an answer (cleaner cars, recycling, energy conservation). The outcome will be a complex dynamic between politics, production, international trade, economics cultural and moral values. (Abela, 2006, Gabriel Lang, 2006, Kasser 2002). In summary, the main culprit behind hedonism would be the development of strong value orientation that puts unrestrained freedom to the forefront. Marketing does not invent or creates wants; it merely surfaces them. Man has always been, in all societies materialistic. In older days poverty didnt allow him/her to indulge into hedonistic lifestyle. The role of marketing in creation of hedonism, is more of a facilitator than of an inventor. (OShaughnessy and OShaughnessy, 2002). Conclusion This paper has recognised that there is debate on what role the discipline of marketing plays in the creation of hedonistic consumers and outlined the argument that marketing has not created hedonistic consumers, that such a stance does not allow for the complexities of human behaviour and motivations and does not take account of the dynamic nature of consumer society. We agree there are associations and parallels in the development of both consumerism and marketing, but there is no evidence to prove cause and effect. However neither is there evidence to disprove. When deciding what marketing strategy an organisation should follow the primary aim is building profitable relationships with the target consumer however, the organisation has many choices in guiding their marketing strategy in terms of which philosophy should underpin the strategy. Many of todays large corporations employ the marketing concept by knowing the needs/wants of the target market and delivering satisfaction better than the competition. (Armstrong et al,2009). Based on the theory that there is a parallel in the patterns between the rise of the hedonistic consumer and the sophistication and intensity of marketing efforts (Abela, 2006) ethical marketers would be advised to consider a move toward the Societal marketing concept a concept that holds that marketing strategy should deliver value in a way that maintains or improves both the consumer and the societys well-being (Armstrong et al, 2009, p14-15). Executed correctly this strategy would provide long term profits and protect both society and the consumer within this framework. sReferences Abela, A.V.

The public sector and tourism

The public sector and tourism But are governments important to tourism, and how do they become involved with tourism management? What are the effects on tourism-has it led to success or failure? Governments and tourism-Tourism needs favourable conditions to thrive-these are stability and security,a sound legal structure with provision of vital services and necessary infrastructure(the roads,water supplies,a favourable environment.)All these the State is able to provide.It is the government who has the influence and political clout for decisions and course direction.The degree of involvement and commitment are most important here.These two factors exist with varying degrees of effect within each country on the globe.PSM or public sector management involves action implementation and policy direction through the government.The principles of accountability on behalf of the public having the necessary support of the legal framework and political system prevailing. Why governments intervene in the tourism sector-First and foremost if there is no monitoring of tourism activity there could occur sudden deterioration of the environment with consequences to the local population.Both facilities and infrastructure as supplied by government contribute as enabling factors with positive benefits of the populations well-being and provision of increased tax revenue.Jobs, also a very important issue are thereby able to be created.See Guide for Local Authorities on Developing Sustainable Tourism WTO(1998:29).Much of the developing world has embraced the immediate benefits to its economy by the pursuit of such investment.Critics would point out the potential for damage by alteration of the localitys social and cultural fabric.There are also leakages whereby the revenue generated is not experienced by the locality it gets diverted elsewhere to overseas investors with a stream of cheap labour coming in to fill potential seasonal employment occupancies for the locals. Politics tend to deal in wider frameworks and this is not alwaysin the best interests of the people.The Franco regime of the 60s utilised tourism for political acceptability.France has always sought to the position of the welfare state on behalf of the poorer members of its society.It is similar to recreational tourism most evident in the Soviet era where cultivation of a workers climate is applicable to the spas,resorts and holiday camps.The government of the UK expounded the potential of the tourism industry for being able to accommodate to large numbers of unemployed during the 1980s when unemployment was at a high level.A transnational body such as the EU has consistently supported financial aid for the creation of infrastructure in the outlying regions of the world.Aid is rendered by the more wealthy nations to those who are impoverished to generate immediate recovery and wealth the Pacific Islands being a case in point. Government intervention and tourism performance-The tourism industry is a very complex category and requires proper coordination   encouraged to achieve positive results.It is pointed out that with extensive government involvement there is inevitable bureaucratic regulation and stiflement this deterring would-be investment from the private sector.Government intervention is necessary where there is present seasonal dependency and the local economy cannot be kept running all year round. The political complexion of local councils is very variable interest in tourism is likely to wax and wane.Government is concerned with obtaining as much quality statistical data as it is able so as to understand how these local economies function and so be able to assist more effectively but still is a very fragmented process.Resolve of conflict directly concerns government intervention;and similar to politics is concerns a balancing strategy between the tourism industry and disenchanted opposition more often than not the local residents themselves. Strategic objectives are more likely to be pursued by government Jeffries(2001) has pinpointed two viewpoints.Firstly redeployment of tourist visitors taking into account the seasonal variation patterns and secondly geographical redeployment in steering tourism flows elsewhere.It is argued for the first strategm that extension of the tourist season with an improved range of visitor and domestic attractions offered during the low season there will automatically occur increased business interest and therefore activity.Employment growth might well occur rather than sustaining a low seasonal level.The second strategm concerns direct intervention and an example of this would be the Languedoc-Rousillon coastal region to the south of Montpellier.A certain number of bespaces were guaranteed for the resort area and improved throughout the 70s and 80s.In this case regional development has occurred to assist an undeveloped region. Locally in the UK the saturation effects experienced from an influx of tourism has prompted definitive measures to contain it;examples of this would be Stratford-upon-Avon,Cambridge with York and Canterbury

Don’t Get Burned Out Essay -- essays research papers

Don’t Get Burned   Ã‚  Ã‚  Ã‚  Ã‚   Burnout. It happens to everyone, everywhere, everyday. Athletes -young, old, professional, amateur, male and female- all experience burnout in different forms and degrees. Burnout is defined as the physical, emotional, and psychological reaction to intense pressure to fulfill obligations, whether they be sports or otherwise. Simply put, people get tired and worn out because they often take on the responsibility of doing too much. Burnout is most common among professional and Olympic athletes that train hard and work hard for long periods of time. However, others can also experience burnout in athletics. Burnout leads to reduced interest in the sport, quality of performance, and then withdrawal.   Ã‚  Ã‚  Ã‚  Ã‚  Burnout is often associated with overtraining, overreaching, and staleness. Overtraining is the point where training is no longer beneficial but harmful. Overreaching is similar to overtraining however the length of time makes the difference. Overreaching for long periods of time leads to overtraining. Staleness is the effect of reaching a performance plateau. Together with overtraining, staleness eventually leads to athlete burnout. In sports psychology, several models exist to help explain, prevent, and treat burnout in athletes.   Ã‚  Ã‚  Ã‚  Ã‚  Stress models of burnout point to stress as the key factor in burnout. Silva’s training stress model is based on the notion that some training s...

McLean vs Arkansas Essay -- Creationism Creation Science

Science is a word that carries with it many meanings - knowledge, truth, a process of examination. But when it comes to setting a clear definition of the term, difficulties arise. Certainly physics is science, and theology isn't. But many disciplines are less intuitively dichotomized, such as the fields of psychology, history, ethics, and many others. Are these sciences? And while it may at first seem like a rather irrelevant issue only for lexicographers and philosophers, in fact the distinction between what is science and what is not is of great importance to society - for in the formation of the public school curriculum, the distinction between science, which must be taught, and religion, which must not be, is essential to keeping education both factual, up-to-date, and constitutional. The 1982 court case McLean vs. Arkansas put in the public spotlight just how important drawing the distinction is. In what has become a landmark case in the creation/evolution legal debate, the Arkansas legislature passed without debate a bill mandating that the state redraw its science education standards so to include in the state's public high school curricula the body of ideas known as "creationism" - the notion that Earth and its inhabitant life forms were formed in the same forms as they are seen today - alongside evolution - the mainstream view of biologists holding that life developed and diversified gradually over millions of successive generations. The concept of creationism has a strong religious history and very deep religious overtones, and the constitutionality of teaching the subject in a public school immediately was questioned. Called to preside over the resulting legal case was U.S. District Judge William Overton. Thu... ...of testability is unclear and the incorporation of unobserved elements is not unique to creationism, so this in and of itself is not a reason to exclude it from a curriculum - and as previously mentioned Darwin considered the two models of creation and evolution on equal scientific grounds in his arguments. Instead, creationism fails on account of the evidence against it. So in the end, while Overton's attempt to determine essential characteristics of science does not stand up to philosophical scrutiny, his decision was correct: creationism is not part of modern science, and does not belong in the modern classroom.

History Recycled in the Works of T.C. Boyle Essay -- Biography Biograp

History Recycled in the Works of T.C. Boyle      Ã‚     "Past and present, sharply separated by the chapter structures, are fused in motifs and unstressed parallels" (DeMott 52).   History's repeating itself is a dominant theme throughout T.C Boyle's novels. If people do not learn from past mistakes, they are likely to fail again. By revisiting history, Boyle teaches the importance of awareness and caution of an ever-changing society. In The Tortilla Curtain a specific migrant problem in the 1930s is modified to fit modern immigration. Candido and America's battle for survival after immigrating to the United States repeats a similar event depicted in Steinbeck's The Grapes of Wrath.   Boyle's twisted short stories in the If the River was Whiskey mirror events in history in the light of modern times.   The similarities between the Van Brunts and the Van Warts in The World's End contribute to identical generations, separated by three hundred years.   Boyle attacks modern society's conceited, self-absorbed attitude, and he discourages reiteration of the past.      Ã‚  Ã‚  Ã‚   In the Tortilla Curtain, Boyle recycles a past   dilemma, as he writes of a problem similar to the "Dust Bowl" migration of the 1930s.   Candido Rincon and his wife America travel from Mexico to America through the "Tortilla Curtain," searching for work, while constantly striving to achieve the American Dream.   In this journey, the Rincons encounter several racist obstacles including a pack of white men who beat and rape America during her pregnancy, leaving her to die.   Constantly searching for work and money takes Candido mentally and physically away from his wife.

Business Management Monica Ashley

Implementing Strategic Change: Monica Ashley’s Experience â€Å"The Monica Ashley Case† illustrates a very conclusive example of how the correct use of power and influence in management is as important as, and sometimes even more important than, having all the right answers and being able to back them up with data. Power struggle, influence, politics, and resistance are all issues within this case study. It also prozides an example that witin project management it is essential to determine the key players, figure out what is important to them and utilize strategic management skills to influence the project. Monica Ashley, a highly driven and ambitious woman was the project manager of â€Å"Project Hippocrates† at HEAL-INC. She had individual power to use the company’s resources and people to accomplish job related tasks and duties. She initially had concerns about taking on the position however, with the personal encouragement and backing by the president of the company, Gary Dorr, she accepted. As the project manager, Monica had access and control over information such as reporting and data supporting the idea of purchasing a digital signal processor from an outside vendor. She also had information about the changes of customer needs and the competitor’s reactions to the changes. Therefore, her colleagues needed to depend on her to solve some of the problems they faced. This gave Monica information power. Although Monica had information power there were several types of power she was missing. Monica lacked reward power and coercive power. She couldn’t give monetary bonuses, promotions or any other form of rewards to colleagues who had done well in the project. More importantly, Monica didn’t have the power to punish anyone who hurt team morale and obstructed the progress of the project by engaging in organizational politics, such as Ralph Parker and Ed Kane. Monica had several years experience in important staff positions, which helped her in transferring her knowledge to this project however she lacked expert power. She didn’t have the expertise in designing and manufacturing of signal processors before taking up the project. She was relatively inexperienced when compared with Parker and she had neither made major contribution to the company nor built close relationship with her olleagues. Her colleagues also less respected her than Parker who had high informal individual power including expert power because of his expertise in analog signal processors. Parker was the vice president of signal processor design, and he believed that he was the only person that could specify the type of processor (analog or digital) to be used in the project. On occasion he discredited Monicas research and stated that it â€Å"wasn’t competant†. Monica chose not to align with Parker and rather continue on her track to comlete the project the best way she saw fit. Monica had legitimate power on the project with her team however she lacked with senior management. Dorr valued a â€Å"peaceful and productive environment† with no â€Å"hot competitors†. Based on her prior converstaion with Dorr it seemed he valued the teamwork aspect more than the expert power. Dorr was frustrated with her thinking that she had legitimate power and described her as â€Å"an Imperial Chinese Emperor. † Parker questioned her legitimate power when he shouted: â€Å"Who the hell do you think you are, going to an outside vendor. † Parker throughout the case used coercive power to intimidate Monica. He taunted her by calling her a â€Å"traitor and a renegade. † The power used by Parker to influence Dorr was not discussed in the case since most of their interaction happened behind closed doors. Though, whatever power used, it surely was more effective than that of Monica. Parker knew how to play the political game, while Monica thought that her numbers and data are going to be enough to get her targets’ buy in. Monica’s influence tactics relied heavily on rational persuasion. Before the Hippocrates project she used this rational persuasion successfully to influence Dorr. She backed up â€Å"her views with data when he (Dorr) asked why she disagreed. † Monica’s attempt to use rational persuasion during project Hippocrates did not yield the same positive results. On the other hand, Parker and Kane knew how to â€Å"play the game† at HEAL-INC. While Monica stuck to one tactic using data and information, Parker and Kane used several tactics in an attempt to influence their targets. This included pressure and time spent forming a coalition. Pressure was exerted on Monica, and she â€Å"ate the bait† and appeared to fight back. Monicas appearance to fight back worked against her since managers are expected to exert self-control. Behind closed doors, Parker and Kane brought Dorr to their side of the argument and used this coalition to marginalize Monica’s proposal. Eventually near the conclusion of the project Monica was removed from her position. Monica realized that she was too caught up in the technical and marketing challenges and she did not focus on assessing the interests of other key players. She had data and content for the project but lacked a foundation because she did not align with others. Her manager, Dan Stella, tried to coach Monica to be more influential but he couldn’t get her to listen to his advice. This proved to be an obstacle for her because when challenged by others Stella did not publically back her up. Stella had a lot at stake for his position in the company and therefore had to look out for himself. Monica also never addressed issues with Parker. She took her coworkers views of Parker as facts and did not bother to talk to him directly. Monica should have taken the opportunity to talk to Parker out of the context of presentations and possibly even work and learn more about him. The goal of meeting with Parker would have enabled her to build trust and rapport with him. She should have also worked actively on finding ways to include Parker in the decision making process. By including others in the project should would have encouraged positive input and perhaps eliminated behind-the-scenes maneuvering. In regards to Stella, rather than viewing his concerns as negative she needed to step back and reassess why he was coaching her. Stella was an invaluable alliance that she should have fostered and recognized. She should have given him the promise of more controlled behavior and listening to his advice, in turn he may have been more willing to publically support her. Monica also made mistakes with Dorr. She went head on with Parker even though Dorr specifically told her not to do so. Her intensity rather than patience and teamwork concerned Dorr. She didn’t do enough talking with Dorr about the project rather provided information in a public setting. The project required Dorr’s support and she did not align with him to build a strong foundation. This misjudgement proved to be a major weakness for Monica. She harmed an opportunity that provided her direct contact with the President of the company, a contact that senior managers should embrace. In order to be more infulential in the future, Monica needs to avoid heavily relying on just the merit of her work and viewing politics with distaste. The â€Å"numbers† are not the only focus for senior management. Effective managers need to also have self-control and show a perception of being team players. Monica needs to work on her relationship with her peers and superiors at HEAL-INC. This includes reaching out to the President Gary Dorr, her boss Dan Stella and last but not least Parker and Kane. In addition to that Monica needs to adapt her influence style. Going forward, she needs to recognize the influence of others and build trusting relationships with the key players involved.

Marketing and Overhead Allocation Rate

Bridgeton Assignment 1. The overhead allocation rate used in the 1987 model year strategy study at the Automotive Component & Fabrication Plant (ACF) was 435% of direct labor dollar cost. Calculate the overhead allocation rate using the 1987 model year budget. Why do you get different numbers? 2. Calculate the overhead allocation rate for each of the model years 1988 through 1990. Are the changes since 1987 in overhead allocation rates significant? Why have these changes occurred? 3. Consider two products in the same product line: Product 1 Product 2Expected Selling Price $62 $54 Standard Material Cost 16 27 Standard Labor Cost 6 3 Calculate the expected gross margins as a percentage of selling price on each product based on the 1988 and 1990 model year budgets, assuming selling price and material and labor cost do not change from standard. 4. Are the product costs reported by the cost system appropriate for use in the strategic analysis? 5. Assume that the selling prices, volumes, a nd material costs for the 1991 model year will not change for fuel tanks and doors produced by the ACF of Bridgeton Industries.Assume also that if manifolds are produced, their selling prices, volume, and material costs will not change either. a. Prepare an estimated model year budget for the ACF in 1991 (1) if no additional products are dropped. (2) if the manifold product line is dropped. Explain any additional assumptions you make in preparing your estimated mode year budgets. b. What will be the overhead allocation rate under the two scenarios? 6. Would you outsource manifolds from the ACF in 1991? Why, or why not? What more information would you want before reaching a final decision?

Management and Golden Rule

At work, we should always be aware of the ones that do not appear to be ethical with decisions made for the company. Golden Rule 1 Samuel 19:1-3: How does Jonathan live by the Golden Rule in disclosing this information to David? Saul is on the hunt to kill David, but Jonathan, the son of Saul, is very fond of David. So Jonathan tells David about the plan and tells him to go hide. Jonathan Is living by the Golden Rule by telling Jonathan of the plan, because he feels that he should warn Jonathan as he would Like the same done to him if the tables were turned.In the working place, you should always show your coworkers respect and you would want the same In return. Causes Significant Harm Samuel 16:1-3: Does Samuel have a duty to disclose this Information to Saul? If not, why? No Samuel does not have a duty to disclose this information, because the Lord, the most high, has asked him to do this. The Lord is the highest leader and his rules should be followed. Sometimes you are asked to f ulfill a task at work in confidence.When asked by the team leader, rules should be followed. Chapter Eleven 1. Human Dignity Isaiah 58:3: Why doesn't God hear the prayers of these managers? God doesn't hear the prayers of these managers because they are fasting, but the fasting ends with arguments and fist fights among each other. They cannot expect to be rewarded for these things. Getting along with each other In the office Is essential to get the Job done. One cannot be rewarded when each other cannot get along. 2.Reciprocity Daniel 2:48-49, 6:1-4: Why is Daniel promoted? What admirable characteristics does he display? Daniel was promoted by the King because he was able to interpret his dream. The dream was interpreted correctly, and the King promoted him. Daniel displays dignity and loyalty to the king and all of its wise men. Being loyal to your am members promotes dignity and trust among the workplace. 3. Servant Leadership Mathew 20:24-28: What are the primary characteristics of Jesus' view of leadership?His primary characteristic view is servant leadership. Leadership is based on power and self-interest. Authority is not an avenue for self-promotion but should be used to serve others. Being a leader you should still have respect for your team. 4. Gift Recognition Acts 6:1-6: Why are these seven men chosen to become early church leaders? These seven were chosen because they were spiritual and full of wisdom. These leaders

Exercise Physiology

Direct calorimetry uses the measurement of heat production as an indication of metabolic rate. * Indirect calorimetry estimates metabolic rate via the measurement of oxygen consumption. * Energy expenditure can be expressed in L†¢min-1, kcal†¢min-1, ml†¢kg-1†¢min-1, METs, and kcal†¢kg-1†¢hr-1. * To convert L†¢min-1 to kcal†¢min-1, multiply by 5. 0 kcal†¢L-1. * To convert L†¢min-1 to ml†¢kg-1†¢min-1, multiply by 1000 and divide by body weight in kilograms. * To convert ml†¢kg-1†¢min-1 to METs or kcal†¢kg-1†¢hr-1, divide by 3. 5 ml†¢kg-1†¢min-1. Efficiency: * Exercise work rate Efficiency decreases as work rate increases * Speed of movement* There is an optimum speed of movement and any deviation reduces efficiency * Muscle fiber type * Higher efficiency in muscles with greater percentage of slow fibers SUMMARY: Net efficiency is defined as the mathematical ratio of work performed divided by the e nergy expenditure above rest, and is expressed as a percentage. * The efficiency of exercise decreases as the exercise work rate increases. This occurs because the relationship between work rate and energy expenditure is curvilinear. To achieve maximal efficiency at any work rate, there is an optimal speed of movement. * Exercise efficiency is greater in subjects who possess a high percentage of slow muscle fibers compared to subjects with a high percentage of fast fibers.This is occurs because slow muscle fibers are more efficient than fast fibers. * Not possible to calculate net efficiency of horizontal running * Running Economy * Oxygen cost of running at given speed * Lower VO2 (ml†¢kg–1†¢min–1) at same speed indicates better running economy * Gender difference * No difference at slow speeds At â€Å"race pace† speeds, males may be more economical that females 170-188 CIRCULATORY RESPONSE TO EXERCISE Organization: arteries branch to form vessels, v essels become microscopic and form arterioles, which develop into â€Å"beds† called capillaries. Capillaries are the smallest and most numerous of blood vessels—exchange of oxygen, CO2, and nutrients. Blood passes from capillary beds to venules that move back to heart and increase in size becoming veins. Mixed venous blood= mixture of venous blood from both upper and lower body in the right side of the heart. *it represents an average of venous blood from entire body.HEART: Right/left side separated by muscular wall called interventricular septum (prevents mixing blood from sides). Valves: Bicuspid/mitral = left atrioventricular valve **atrioventriculars close when heart contracts to prevent backflow. Tricuspid= right atrioventricular valve Semilunar valve (pulmonary semilunar)- b/w right ventricle and pulmonary artery. Prevents backflow from arteries into ventricles. Aortic valve (aortic semilunar)= b/w left ventricle and aorta. Also prevents backflow†¦ Right si de pumps deoxygenated blood to pulmonary circuit so oxygen can be loaded and CO2 released.Left side pumps oxygenated blood to body via systemic circuit. RIGHT: to lungs LEFT: to body Heart sounds are due to closing of atrioventricular valves (first sound-systole) and the closing of aortic and pulmonary valves (second sound-diastole) Wall of heart is 3 layered: 1) outer layer is epicardium, 2) muscular middle layer called myocardium, 3) inner layer endocardium. Myocardium contracts to force blood out. Right and left coronary arteries supply myocardium Cardiac muscle fibers are shorter than skeletal and are branched and involuntary. Heart muscle fibers are all connected via intercalated discs- transmit electrical impulses.They are leaky membranes that allow ions to cross b/w fibers (contract together= functional syncytium). *atria contract separate from ventricles because there is a separating layer of CT *heart is only type 1, slow fiber- highly aerobic, many mitochondria (more than skeletal). Cardiac cycle: Systole- contraction phase (blood ejected) Diastole- relaxation period (arterial BP decreases– filling) There is also an atrial systole and diastole. Atrial contraction during ventricular diastole, atrial relaxation when ventricular systole. *SO there are TWO steps of heart pumping. *atria contract together, which empties arterial blood into ventricles. . 1 second and then ventricles contract to deliver blood to systemic and pulmonary circuits.*when atria relax, blood flows into them from venous circulation as they fill, pressure inside increases. Increase in HR less time spent in diastole (not as much impact on time in systole until at high HR) Arterial Blood Pressure: -greatest in arteries BP = the force exerted by blood against the arterial walls. Determined by how much blood is pumped and the resistance to blood flow. -male: 120/80, female: 110/70 systolic/diastolic dif between the two is calls â€Å"pulse pressure† â€Å"mean arterial pr essure†= av pressure during cardiac cycle. determines rate of blood flow through systemic circuit Mean arterial pressure = DBP + . 33 (pulse pressure) (DBP: diastolic blood pressure) (pulse pressure: dif between systolic and diastolic pressure) SO, if someone has bp 120/80, Mean arterial pressure= 80mmHg + . 33(120 – 80) = 93 mmHg *but this calculation is only used for cardiac cycle at rest.Hypertension- increases workload on left ventricle so cardiac mass increases, but this eventually results in diminished pumping capacity. Also increase risk for other disease/damage of body parts like brain and kidneys. 20% all US adults Factors influencing arterial BP: ) cardiac output—amount of blood pumped from heart 2) total vascular resistance – sum of resistance to blood flow by all systemic blood vessels. —blood volume, blood viscosity Mean arterial blood pressure = (cardiac output x total vascular resistance) *so increase in either will increase the mean art. BP Blood pressure increases when increase in: blood volume, HR, SV, blood viscosity, peripheral resistance. And it decreases when any of those decrease. BP regulated short term by the sympathetic NS, long term by the kidneys (bc they control blood volume). Baroreceptors- sense arterial blood pressure in carotid artery and aorta.Increase in pressure send impulses to CV control center which will decrease the sympathetic activity (lowers cardiac output and/or reduces vascular resistance lowers BP). Decrease in BP reduction of baroreceptors activity to brain CV control center increases sympathetic activity raise BP to normal Electrical Activity of the Heart: Sionatrial node (SA node)- in the right atrium (by the vena cava). responsible for spontaneous electrical activity in normal heart, it’s the pacemaker. Occurs due to decay of resting membrane potential (bc of diffusion of NA during diastole).When SA is depolarized and reaches threshold, a wave of depolarization is spread over the atria contraction! Wave of atrial depolarization needs special conductive tissue to transport it to the ventricles. This conductive tissue is called the atrioventricular node (AV node- in floor of right atrium). When blood from atria empties into ventricles, the conductive pathways branch into smaller fibers called purkinje fibers that spread the wave of depolarization through ventricle so it can contract. Electrocardiogram (ECG)- recording of electrical charges in myocardium during cardiac cycle. –ability of hear to conduct impulses.P wave- depolarization of atria QRS complex- depolarization of ventricles and atrial repolarization(during beginning of systole, aprx . 10 seconds after Pwave) T wave- ventricular repolarization (same time as QRS, but at the beginning of diastole) CARDIAC OUTPUT (Q): Q = HR X SV Regulation of heart rate: -because SA node controls HR, changes in HR involve factors influencing SA node. Most influence over HR: parasympathetic and sympathet ic NS Parasympathetic NS- acts as braking system to slow HR using vagus nerve which touches SA and AV node and releases acetylcholine decrease activity of SA and AV nodes due to hyperpolarization= reduce HR. —initial increase in HR during exrcise up to 100bpm is due to decrease in parasympathetic tone. Sympathetic fibers use cardiac accelerator nerves to innervate both SA node and ventricles.Increase HR and myocardial contraction when they release norepinephrine. –beta receptors *all beta-blocking drugs will decrease resting HR and exercise HR. CV control center regulates- pressure receptors in right atrial respond when there is increased pressure by increasing Q to reduce the BP. Body Temp also influences HR. increase temp = increase HR Regulation of stroke volume: ) end-diastolic volume (EDV aka â€Å"preload†) (volume of blood at end of diastole) 2) average aortic BP 3) strength of ventricular contraction EDV- Frank and Starling, stronger contraction with hig her EDV bc there is more stretch of ventricles. EDV influenced by rate of venous return to heart- more return= higher EDV. Venous return regulated by: 1) venoconstriction – reduced volume capacity of veins to store blood. *sympathetic control- activates organ increase HR (the parasympathetic inhibits activation decrease HR) 2) muscle pump—muscles contract and compress veins blood pushed to heart.Venous return reduced when muscles are contracted. isometric exercise, mechanical. 3) respiratory pump- breathing decreases pressure in chest and increases abdominal pressure so venous blood flows from abdominal into thorax and increases return. *more respiration in exercise Aortic pressure (mean arterial pressure/afterload)- to eject blood, pressure in left ventricle must be more than in the aorta. Increase in aortic pressure= decrease SV. Less afterload during exercise bc arteriole dilation reduces afterload. Circulating epinephrine-norepinephrine (increase Ca+ entry) and dir ect sympathetic stimulation of heart by cardiac accelerator nerves.Increase in sympathetic stimulation of heart increases SV at any level of EDV. HEMODYNAMICS: -blood flow is in a continuous loop. Physical characteristic of blood- composed of plasma (watery portion, contains ions/proteins/hormones) and cells (called the hematocrit: RBC/platelets/WBC). Hematocrit= 42% of blood (38% in college women), the rest is plasma. RBCs are largest part of a blood cell—influence viscosity. Anemia decreases RBC, so decreases viscosity Relationships among pressure, resistance, and flow: Rate of flow is proportional to pressure difference. Inversely proportioned to resistance.Blood Flow= change in pressure/ resistance -Change in pressure is the dif between the two ends of the circulatory system -resistance due to length of vessel and viscosity, and radius of vessel **Blood flow increases with increase in BP or with decrease in resistance. -during exercise blood flow increases mainly due to d ecrease in resistance with small rise in pressure. Resistance = (length x viscosity)/ radius^4 (**so radius is VERY important-vasoconstriction/vasodilation) Sources of vascular resistance: -vasoconstriction/vasodilation the greatest vascular resistance in blood flow occurs in arterioles.Pg 188 – 196 Changes in oxygen delivery to muscle during exercise: Metabolic need for O2 increases so there is an increase in blood flow to muscle- increase O2 delivery by 1) increased cardiac output and 2) redistribution of blood flow from inactive organs to working skeletal muscle. Changes in cardiac output during exercise: -cardiac output increases in proportion to metabolic rate for task -maximal cardiac output decreases after 30 yrs of age mostly bc of decreased maximal heart rate with age. Cardiac output = heart rate X stroke volume Max HR = 220 – age (years)Changes in Arterial-Mixed Venous O2 content during exercise: -change in arterial-mixed venous oxygen difference (a – VO2 diff)during exercise. It represents the amount of O2 taken from 100 ml of blood by the tissue during 1 systemic circuit. The relationship between cardiac output (Q), a – VO2 diff, and oxygen uptake is given by the Fick equation: VO2 = Q X (a- VO2 diff). Fick equation: VO2 is equal to the product of cardiac output and the a-VO2 diff. *SO INCREASE IN CARDIAC OUTPUT OR (a – VO2 diff ) WOULD ELEVATE VO2. Redistribution of Blood Flow During Exercise:Increase flow to skeletal muscles and decrease to less-active organs like liver, kidneys, GI tract. Increase in muscle blood flow and decrease in splanchnic blood flow change as a linear function of %VO2 max. -at rest aprx 15-20% total cardiac output is directed to skeletal muscles. -during maximal exercise 80-85% of total cardiac output goes to skeletal muscle (to help meet oxygen needs for contracting) -during heavy exercise % that goes to brain is reduced compared to rest. -total coronary blood flow increases due to incre ase in cardiac output -reduction of blood flow to skin and abdominal organsRegulation of local blood flow during exercise: Regulated with arterioles in skeletal muscles that have a high vascular resistance at rest (due to adrenergic sympathetic stimulation which causes vasoconstriction). This results in low blood flow to muscle (4-5 ml/min per 100g muscle) but this is still 20-25% total flow from heart. **autoregulation (an intrinsic metabolic control) -vasodilation (opens vessels) results from local changes during exercise like decrease in O2 tension, increase in CO2 tension, nitric oxide, potassium and adenosine concentrations, increase in acidity.Vasodilation reduces vascular resistance and therefore increases blood flow. Also aided by recruitment of cappilaries- at rest only 5-10% of capillaries are open, all are open during heavy exercise. **level of vasodilation regulated by metabolic need of the muscle (intensity and # of motor units recruited determines blood flow to active muscle fibers) during exercise, vascular resistance in skeletal muscle decreases and vascular resistance to flow in the visceral organs/other inactive tissue increases. *because on increased sympathetic output to these organs regulated by CV control center. increase in visceral vasoconstriction during exercise decreases blood flow to viscera by 20-30% resting value. During exercise in upright position, SV reaches plateau at 40% VO2 max, therefore, at work rate about 40% VO2 max, the rise in cardiac output (Q) is due to increased HR only.CIRCULATORY RESPONSES TO EXERCISE: HR and blood pressure at any VO2 (oxygen uptake) are higher in arm than in leg -higher HR in hot/humid conditions emotional influence- HR increase with high emotion because increase in sympathetic NS activity. Does not generally alter peak HR or blood pressure during exercise itself but does elevate pre-exercise HR. ransition from rest to exercise- increase in HR and SV and cardiac output at beginning of exercise (a fter 1st second! ) then if work is constant it plateaus recovery from exercise- recovery from short-term/low intensity is rapid. Recovery after exercise better in trained individuals bc their HR doesn’t get as high. Recovery from long-term is slower because elevated body temp. incremental exercise- HR and cardiac output increase in direct proportion to O2 uptake. More O2 uptake = more blood flow to muscles. Plateau of cardiac output and HR at 100% VO2 max (no more hemoglobin to transport O2).The increase in HR and systolic BP results in increased workload on the heart (increased metabolic demand on heart estimated by: double product = HR x systolic BP) maximal exercise increases workload on heart by 500% Useful equation to tell patients with coronary artery blockage how they can exercise. **cardiac output increases because decrease in vascular resistance to flow and increase in mean arterial blood pressure. Arm vs. Leg exercise- HR and BP higher in arm because greater sympath etic outflow to heart during arm work when compared to leg work.Large increase in BP for arms because of vasoconstriction in inactive muscle groups. Large muscles (legs) have more resistance vessels dialated, so there is lower peripheral resistance and lower BP (cardiac output x resistance= pressure). Intermittent exercise- (interval training), recovery of HR and BP depends on level of fitness, environmental conditions, and duration and intensity. Recovery not complete if the temperature is high because that increases HR. with repeated bouts of light exercise, many repetitions can be preformed. Prolonged exercise- cardiac output at constant level.SV declines while HR increases because the increase (cardiac output constant bc HR increases and balances SV decrease). Cardiovascular drift= increase in HR and decrease in SV during prolonged exercise. , it is due to rising body temp and reduction in plasma volume. Reduction in plasma volume reduces venous return to heart and thus decrease in SV REGULATION OF CARDIOVASCULAR ADJUSTMENTS TO EXERCISE –increase in sympathetic stimulation of heart and vasodilation of arterioles and increase resistance of vessels in less-active areas= increase cardiac output so that blood flow to muscle matches metabolic needs.Central command- CV change due to centrally generated cv motor signals **also modified by heart mechanoreceptors, muscle chemoreceptors, muscle mechanoreceptors, and pressure-sensitive receptors (baroreceptors) â€Å"tuners† during exercise: muscle chemoreceptors- muscle metabolites (K, lactic acid, etc. ) muscle mechanoreceptors- force and speed of muscular movement baroreceptors- change in arterial BP- regulate arterial BP Page 267-269, 277-280 VO2 max = HR max X SV max X (a- vO2 dif)max STROKE VOLUME SV = End diastolic volume(EDV) – End systolic volume (ESV) *EDV increase ecause increase in ventricle size/increase in venous return (â€Å"preload†), increase in myocardial contractility, and decrease in resistance to blood flow out of heart (â€Å"afterload†) End diastolic volume (EDV) Left ventricle increase with endurance training bc of volume loading during exercise Plasma volume increases with endurance training (loss of plasma volume = decrease VO2 max in first weeks of detraining) **EDV increase with training. FRANK-STARLING MECHANISM: increase stretch of ventricle = increased SV Cardiac contractility- strength of contraction when fiber length, afterload, and HR are constant.Afterload- peripheral resistance against which the ventricle contracts in order to push portion of EDV into aorta. Decrease in resistance = increase max cardiac output, SO arterial BP is unchanged (MAP = Q x TPR) **endurance training lower resistance in working muscle to facilitate higher blood flow blood pressure falls when muscles capacity for blood flow exceeds hearts ability to provide it.. —to maintain BP some of muscle mass is vasoconstricted (other is vasodialated) tra ining decrease resistance of vascular bed to match increase in max cardiac output to maintain BP Arteriovenous O2 difference: increase in difference could be due to elevation of the arterial oxygen content, or decrease in the mixed venous oxygen content. -increase capacity of muscle to extract O2 after training probably because increase in capillary density (mitochondria too) accommodate more blood flow *training-induced increase in maximal SV due to increase in preload and a decrease in afterload.Preload increased because end diastolic ventricular volume and associated increase in plasma volume. Afterload decreased because decrease in arteriolar constriction in trained muscles increases maximal muscle blood flow but no change in mean arterial BP. in young, sedentary ppl, 50% of increase in VO2 is bc of increase in systemic a-VO2 dif (due to increase in capillary density). Decrease in VO2 max when you stop training because decrease in max SV and decrease in oxygen extraction. 277-28 0 net cost of walking is ? of net cost running use pace maker test for kids field test for CRF use walking, running, stepping. Can test many ppl at low cost. Hard to measure response for some, and motivation can be a variable. VO2 max estimates from all-out run tests are based on the linear relationship b/w running speed and oxygen cost of running.VO2 max estimated in endurance test is influences by CV function and % body fat. Canadian home fitness test: submaximal, uses lowest two 8-inch steps in a staircase. Evaluates cardiorespiratory fitness using post-exercise HR. 1 mile walk test: VO2 based on age, weight, sex, time, HR improved fitness: lower HR and/or time and higher VO2 max cardiorespiratory fitness measured using: treadmill, cycle ergometer, stepping bench measured by: palpation (carotid/radial artery), stethoscope (systolic- 1st korotkoff sound, diastolic- 4th sound), ECG ncreased metabolic demand on heart estimated by: double product= HR x systolic BP -double product is estimate of myocardia O2 demand arrhythmia- irregularity in normal electrical rhythm: atrial fibrillation, premature contractions conduction disturbances- depolarization is slowed/blocked (first-degree AV block or bundle branch block) myocardial ischemia- inadequate perfusion of the myocardiumflow limitation= O2 insufficiency (angina pectoris- symptom)(ST segment depression-sign upsloping, horizontal, downsloping—downsloping is worst) teady state:HR measured over 15-30 seconds post exercise HR: measured for 10 seconds within first 15 seconds of stopping exercise, then multiple the # by 6 HR and systolic BP increase with exercise intensity * Typical measurements obtained during a graded exercise test include heart rate, blood pressure, ECG, and rating of perceived exertion. * Specific signs (e. g. , fall in systolic pressure with an increase in work rate) and symptoms (e. g. , dizziness) are used to stop GXT. VO2 max: â€Å"gold standard† to measure CRF VO2 increases wi th increasing loads on a GXT until max capacity reached- VO2 estimated based on final work rate achieved in graded exercise test- can also be estimated from HR responses to submaximal exercise using age, also consider environmental factors.Estimation of VO2 max from last work rate: Poorly fit individuals take longer to achieve the steady state at moderate/heavy work rates may overestimate the VO2 max when using formula Estimation of VO2 max from submaximal HR response: HR plotted against work rate (or estimated VO2) until termination criterion of 70%- 85% of age-adjusted maximal HR reached (220-age). careful of environmental factors- dehydration, temp, emotions, medication * VO2 max Estimation of VO2 max from Last Work Rate Estimation of VO2 max from Submaximal HR Response CRITERIA FOR ACHIEVING VO2 MAX: * Leveling off of VO2 with higher work rate <150 ml†¢min–1 or <2. 1 ml†¢kg–1†¢min–1 * Post-exercise blood lactate >8 mmoles†¢L†“1 * R >1. 15 * HR within 10 beats†¢min–1 of age-predicted maximal HR * Usefulness has been questioned * Should not expect subjects to meet all criteria * Graded Exercise Test: Protocols Treadmill Cycle Ergometer Step Test * Graded Exercise Tests: MeasurementsHeart Rate Blood Pressure ECG Rating of Perceived Exertion Termination Criteria Treadmill- don’t have to adjust for body weight in calculation because subject is carrying their own weight ( so VO2 is proportional to weight).
