zora neal hurston essays

zora neal hurston essays In her 1928 essay, How It Feels to be Colored Me, Zora Neale Hurston meticulously understates the hardships of being black. Among many occupations held by Hurston, she was that of an anthropologist who studied the origin, behavior, social, and cultural development of humans. Hurston was not justifying the stereotypes of being Colored. Throughout How It Feels to be Colored Me she provides opportunities to use being Black as a method of empowerment as opposed to an aspect of tragedy. Hurston illustrates how she used whites for entertainment just as they did her; she points out the power and beauty of womanhood outside of race, and later states the controversial theory that slavery was the price paid for civilization. During a time when Blacks would hardly approach white people, Hurston found it most amusing to not only entertain them but to be a recipient as well. Hurston was immerged in a Negro community so white tourists were quickly noticed when traveling. Rather than cautiously watching them from a distance, as the majority did, Hurston delighted herself in being the head of the welcoming committee. She would wave, salute, sing and dance around on her front porch, which she refers to as her gallery seat, until she engaged the tourist in play. She found them intriguing, and her performances intrigued them. They were intrigued in several ways to the less than thirteen year old. These white tourists enjoyed, even rewarded Hurston for her joyful tendencies. While the Negro community condemned her for her outgoing antics, white tourists would give her silver for her performance. The white tourists may have used Hurston for their entertainment. To watch a young, vibrant, outgoing Black c hild prance around, singing, dancing, and surveying them could tend to be amusing. In retrospect, Hurston must have felt quite excited holding the center of the national stage, with s...

Supply management and purchasing are considered hair raisers in any company and it is a major concern for the purchasing manager who must maintain and adhere to a budget. Service focused businesses are beginning to dominate major economies. When a company is marketing a product, it is their job to ensure that the product iscompelling, the companyalsoneeds to have the manpower to handle the workload of producing the product at an attractive price.Companies must recognize purchasing as supply management if they are going to remain competitive. In market transactions the price of the goods or service is determined by supply and demand in the market.Tocreate aprofit,the purchase price should be lower than the selling price. When we look at the example ofCase 3-11 Carmichael Corporation, they needed the product MS-7 but would it be worth it in the end to purchase it? The price of the MS-7 had greatly increased and that could cut into the company'sprofitability. At this point, they canconsiderother products that are cheaper but produce the same results. This is where strategic cost management comes into play. When a companyunderstandcosts that support their strategic position and which costs have either no impact or weakens it, the goal isto reduce the total costs while improving the strategic position of the business. Before Amanda Tellford, of the Carmichael Corporation decides to cut corners she needs to understand that cost is a strategic issue and should be looked at in the long term. She really needs to get a better understanding ofhersuppliers and their business and somehow help them toimprove their processes and with the end goal of loweringthe company's costs.Her business and the product that they market are unique.Since Brisson is planning to corner the market, I feel that she probably will be better off if she joined forces with Brisson. The MS-7 that her company needs will be made locally within the US and even though the price might be higher than what she's used to the product turn around should be quicker. It is not in the best interest for her company to try to manufacture the product themselves because they don't know how well the product will do in the future months. So, let Brisson make the initial investment and as the market grows and gets stable then the Carmichael Corporation can make and manufacture their own MS-7. But, on the other hand if everything busts and it's a failure they are not out of any money. She needs to keep in mind the learning curve and man hours that it will take to manufacture the MS-7 and to make a huge investment like that when you are not sure is notbusiness smart. The companyshould all concentrate on the need to provide the best products to their customers as a wayof beating or remainingcompetitivein the market rather than over concentrating on what other companies are doing (Weele, 2010).Amanda will waste precious time and resources worrying over things that can't be changed. Deliver a superior product and have good service and the customers will come. Even if

Damages recoverable electronic funds transfer transactions under UK Dissertation

Damages recoverable electronic funds transfer transactions under UK Law - Dissertation Example To create a process that is safe for the customers, and well protected from losses arising from a lack of adequate legal remedial processes, is of utmost importance for a successful banking operation, which by its very nature of handling large amounts of money, comes under ‘high-risk’ business practice. Such high risks associated with banks comprised mainly of credit-interest risks, law related issues, and liquidity risks. With the start of the internet banking or the electronic funds transfer system has further increased these risks while creating some additional new ones, which may arise from the banks trying to circumvent regulatory and supervisory norms, in order to expand their customer reach. Other risks of a legal nature include the ambiguities on various legal processes and requirements that vary from country to country. 3 Though there are laws that specifically address the issue of frauds and other legal problems within internet banking and funds transfer, not m uch attention has been given to the area of remedies. In this era of high-end technology, it is necessary to review and re-examine various remedial processes like damage claims and injunction, within the electronic funds transfer transaction process. Discussion Banking system and electronic funds transfer under the English law: Under the English law, 'banking business' 4 is seen as comprising of two main basic features: â€Å"acceptance of money from and collection of cheques for their customers and placing them to the customer’s credit, and honouring cheques drawn on the bank by its customers and debiting customers' account accordingly.†5 The term 'banking' has been framed differently within the English legislation, and is covered under Banking Act 1979, the Banking Act 1987 and, the Financial Services and Markets Act 2000 also referred to as FSMA 2000.6 In the context of modern banking system through the internet, â€Å"electronic banking† or â€Å"e-bankingà ¢â‚¬  is defined as banking operations conducted by authorised banks (or their official representatives), from a remote location through tools that function under the bank's direct management or through outsourced agents. Thus, e-banking encompasses an entire set of process through which a customer can transfer funds electronically, without having to visit a bank physically, and these processes also includes services where the customers can access their accounts, conduct business transaction, receive necessary information on different financial services and products all the Internet (fig 1). In UK, all electronic modes of payments/transactions come under the jurisdiction of the â€Å"law of contract and agency and the customs and usages of banking.† 7 Fig 1: Various processes and available services as seen within e banking.8 As

How children with challenging behaviours can be included in the Literature review

How children with challenging behaviours can be included in the classroom - Literature review Example Though there is much disagreement on the exact definition, yet the intellectual community is aiming at identifying pragmatic solutions to the issue. For this reason, it is first crucial to understanding the reasons behind such behaviours which may range from general communication difficulties to other external factors, sometimes even socio-economic disadvantages or an underlying medical cause (Knowles & Landen 2012). Thus, once the underlying causes are identified, policy initiatives can be taken at the institute level which would then be needed to be incorporated into classroom to incorporate children with needs in the classroom. Establishing and Promoting positive behaviour towards children implicating challenging behaviour, on part of the teachers, is the most effective technique to resolve the issue early on. However, the main question arises in context to which techniques to apply and how, in order to ensure a secure and an encouraging environment for such children with needs. Moreover, the policies would only be effective if they contribute toward building a positive culture in the institute where an encouraging environment can be reaped to help the children with challenging behaviours. Analyzing literature is essential to understanding what has been done in the past to deal with the issue at hand, and more importantly the effectiveness of the techniques being applied in the past. More importantly, literature review will lead toward better understanding of the topic at hand which will further provide logical insights on the research question. Moreover, literature review will offer a holistic analysis of the children with challenging behaviours, which will help in generalizations adding further knowledge to the topic at hand. The topic is a policy concern for all institutions imparting education to children, since these institutes leave a serious impact on the students. Not

Personality Disorders Essay examples -- Papers

Personality Disorders Personality disorders indicate the presence of chronic rigid and maladjusted personality traits, through which the person's interpersonal or professional functioning is negatively affected, or which lead to personal unhappiness and problems (Louw, 1990). Discuss this statement from a biopsychosocial frame of reference and refer to one personality disorder in any cluster to illustrate your answer. The Biopsychosocial model: ========================== The biopsychosocial model (Engel, 1980, cited in Paris, 1993) suggests an integrated approach that understands psychopathology in terms of multiple causes, none of which is sufficient on its own for the development of the disorder. These factors could include biological vulnerability, the psychological impacts of life experiences and the influence of the social environment all of which may factor as risk variables or protective variables. The biopsychosocial model differs from more linear cause and effect approaches such as heredity in that it is only the cumulative interactive effects of the multiple variables can produce the overt disorder. Personality disorders ===================== Personality disorders are characterised by inflexible and longstanding maladaptive personality traits that cause significant impairment and subjective distress for the individual. The signs of a personality disorder display in adolescence or early adulthood. Individuals differ to the extent that they possess Personality traits and it may be difficult to decide whether the trait exists to an extent that can be considered pathol... ...tice, 10, (2), 161-165.

Nursing Shortage Essay

Abstract Compelling evidence suggests that regions of the United States face a nursing and physician shortage that our legislators, health officials, and medical professionals must address. To ensure that quality medical care is not harshly impacted, the hospitals and public health leadership, in general, will need to tackle the nursing shortage with solid long-term solutions. It is no secret that the United States faces a critical nursing shortage, a trend that potentially threatens to undermine quality medical care. One single area of concern does not affect the shortage. In fact, the hospitals, and nursing in particular, are witnessing a combination of problems that range in salary structure, medical economics/cost containment, post-graduate education, and an aging workforce (pending retirements of baby-boomers). The public health industry is not sitting idly by to address the shortage. It is critically reviewing the needs for both existing professions. Definition of Nursing Shortage Nursing shortage is defined as the inadequate number of qualified nurses to meet the projected demand for nursing care within a healthcare setting, where the demand for nurses is greater than the supply. History of Nursing Shortage Historical knowledge is important to analyze the present and prepare for the future. As we can see from the current shortage in America today, we learn that it is not a new problem. However what makes this current nursing shortage situation unique is that the causes are related to a multifaceted range of issues. The current nursing shortage is connected to supply and demand factors, demographic changes, population growth, and fewer students enrolling in nursing schools, RNs who are retiring or leaving the workforce and a growth in the baby boom population who will demand more healthcare services in the near future. These factors are occurring while many nurses are retiring and more jobs are being created. In addition, the nursing shortage is actually a worldwide phenomenon with areas like Western Europe, Australia, Canada and the Philippines facing shortages as well. Economic factors have also contributed to the nursing shortage in the United States. Mark Genovese, spokesperson for the New York State Nurses Association explains, â€Å"For many decades the shortage was cyclical but as the economy tightened and as the insurance industry moved to a managed care model, there was less money in the system and hospitals had less money to work with and tighter budgets.† Budgetary limitations affected the nursing workforce as many nurses began leaving the profession altogether. â€Å"They were forcing RNs to do more with less, handle more patients and work more hours. RNs started to leave the workforce because of the working conditions and fewer RNs entered the system,† explains Mark. Americans are also demanding more quality healthcare services while many RNs are retiring, further exacerbating the problem. The HRSA has stated: â€Å"to meet the projected growth in demand for RN services, the U.S. must graduate approximately 90% more nurses from U.S. nursing programs.† Decreased staffing means that there are fewer nurses to work with patients. This impacts job satisfaction and causes work related stress. In some cases it has led to many nurses leaving the profession altogether. A 2010 study published in Health Services Research found that over 75% of RNs feel that the nursing shortage is a huge problem that affects their quality of work as well as patient care and the amount of time that nurses can spend with individual patients. Another important factor contributing to a lack of nurses is that there is a shortage of nursing school faculty to train a new generation of nurses in colleges and universities. The AACN’s 2008-2009 Enrollment and Graduations in Baccalaureate and Graduate Programs in Nursing report found that nursing programs in the U.S. did not enroll 49,948 qualified students into their bachelor and graduate degree programs because they did not have an adequate number of faculty, clinical practice sites, teaching space, and were constrained by budgetary limitations. Two thirds of the nursing program respondents reported that a big reason for not accepting students was due to not having enough nurse faculty on hand. The Southern Regional Board of Education conducted a study which found that the nursing faculty shortage in 16 states was caused by vacant faculty positions, retirements, resignations and a shortage of new candidates applying for faculty positions. Shortages like this pose a threat to the availability of nurse education. Defining the Problem For those students interested in careers in healthcare, becoming a nurse right now could be the best decision for you. Currently, the United States is facing a severe nursing shortage. For several reasons, the number of nurses graduating and entering the workforce, and those already in the profession, is not enough to fill the growing demand. Currently, RNs are the largest group of healthcare workers in the US at roughly 2.6 million and that still isn’t enough to meet the need. According to experts, by 2012, there could be around 1.1 million unfilled nursing positions in the United States. In the most basic sense, the current global nursing shortage is simply a widespread and dangerous lack of skilled nurses who are needed to care for individual patients and the population as a whole. The work of the world’s estimated 12 million nurses is not well understood, even by educated members of society. But nursing is a distinct scientific field and autonomous profession whose skilled practitioners save lives and improve patient outcomes every day in a wide variety of settings. In the Truth’s view, the vast gap between what skilled nurses really do and what the public thinks they do is a fundamental factor underlying most of the more immediate apparent causes of the shortage. These causes include nurse short-staffing (due to inadequate pay and long work hours), poor work conditions, the aging nursing workforce, expanded career options for women, nursing’s predominantly female nature, the increasing complexity of health care and care technology, and the rapidly aging populations in developed nations, to name a few. Other causes of the nursing shortage episode include: the aging baby boomer population and lack of employee incentives. There were seventy-six million Americans born between 1946 and 1964 and are now classified the Baby Boomer Generation. As this population reaches retirement age and beyond, they are requiring more medical treatments and nursing home and long term care facilities. This country is also seeing an increase in population in general, projected to grow 18% over the next two decades. With more patients flooding the healthcare system, there simply aren’t enough nurses to meet this growing need. However, those currently employed in the nursing field should be rewarded for being encouraged and motivated to stay in such a questionable field of employment. In light of this nursing shortage, it should be relatively easy to find gainful employment after graduation should you choose to study nursing. According to the Bureau of Labor Statistics (BLS), more than 581,000 new Registered Nurse (RN) positions will be created through 2018, which will increase that workforce by an astounding 22%. The BLS also estimates that even as other sectors of our economy continue to suffer, the healthcare sector will only continue to grow. Since the recession began, more than 600,000 positions have been created in the healthcare industry. With so many Americans out of work in other fields, a career in healthcare, specifically in nursing, might be a viable career choice. Literature Review Today, the average age of nursing faculty in baccalaureate and graduate degree programs is 51.5 years and the rate of projected retirements will exceed the rate of re placements. Nurses enter the faculty role later in their careers and typically retire at an earlier age, around 62.5 years. More efforts need to be put into place to encourage those already teaching to remain in their positions even if it is in a limited capacity while future faculty are educated. What factors are present that facilitate the desire for nursing faculty to retire? Kowalski, Dalley, and Weigand (2006) conducted a cross-sectional, randomized study of 129 nurse educators teaching in 61 schools of nursing to find out what personal decisions influenced their retirement plans. With a 37.6% response rate, results reflected that the mean age of planned retirement was 64.4 years. However, the mean age respondents would like to retire was 62.4. Factors influencing retirement included workplace issues, personal and family health, attitudes about retirement, and financial security. One of the most important factors influencing retirement plans was financial security. Faculty members who were financially secure retired earlier. Job satisfaction was another important influencing factor resulting in early retirement. In lieu of the faculty shortage, the authors contend that studies such as this will offer insight into future retirement trends which may help bridge the gap between supply and the demand of nurse educators (Kowalski et al., 2006). From the results of this one study it may be important to consider the needs of the aging faculty by providing healthy, satisfying, and stimulating work environments, appropriate benefits packages, and relaxing mandatory retirement ages. One serious factor contributing to the faculty shortage is financial. Not only are academic salaries much lower than they are for clinical practice and administrative positions of advanced practice nurses, but the cost of securing advanced academic degrees is costly. In 2004, the average salary of a master’s-prepared nurse practitioner in a clinical setting was $80,697 compared to $60,831 for that of a master’s-prepared nursing faculty member (Nevada Nurses Association, 2004). By increasing academic salaries and providing tuition allowances in return for teaching will indeed make teaching a more attractive career choice (Yordy, 2006). Another important factor affecting the faculty shortage is that of job satisfaction, stress, and burnout. To maintain current faculty on the job, more research should be conducted on factors affecting job satisfaction and what works to provide a better environment. Gormley (2003) performed a meta-analysis study on nursing faculty job satisfaction and which factors had the greatest influence using a sample of six studies from 1976 and 1996. Nursing faculty are pressured not only to educate future nurses to provide safe and competent care, but also have many other professional responsibilities, such as publishing, conducting research, writing grants, performing community service, and maintaining their own competencies (Gormley, 2003). These responsibilities combined can become overwhelming and lead to job dissatisfaction especially as the faculty is aging. In Gormley’s study (2003), factors that affected job satisfaction were perception/expectation of the leader’s role in curriculum and instruction, suggesting that the dean’s role has significant effects on faculty’s job satisfaction and role conflict/ambiguity. Shirey (2006) argues that prolonged stress can lead to burn-out in many faculty who then become â€Å"deadwood,† jeopardizing the quality and spirit of the institution. These faculty members can ward off potential new faculty who are even more vulnerable to the stresses of the teaching role. It is imperative that academic institutions pay close attention to the needs of their faculty. Mentoring programs, self-renewal, and organizational engagement are key strategies to prevent burnout (Shirey, 2006). â€Å"A carefully structured and deliberate mentoring program can be an invaluable orientation as schools of nursing seek to provide an academic environment that is conducive to the professional and scholarly development of adjunct faculty members† (Peters & Boylston, 2006, p. 64). One serious factor contributing to the faculty shortage is financial. Not only are academic salaries much lower than they are for clinical practice and administrative positions of advanced practice nurses, but the cost of securing advanced academic degrees is costly. In 2004, the average salary of a master’s-prepared nurse practitioner in a clinical setting was $80,697 compared to $60,831 for that of a master’s-prepared nursing faculty member (Nevada Nurses Association, 2004). By increasing academic salaries and providing tuition allowances in return for teaching will indeed make teaching a more attractive career choice (Yordy, 2006). Program Analysis Possible Solutions For sustained change and assurance of evading the forthcoming shortage, solutions must be developed in several areas: education, health care systems, policy and regulations, and image. This shortage is not exclusively a nursing issue, but will require a collaborative effort among nursing leaders, practitioners, health care executives, government, and the media. Creating Cultures of Retention The American Nurses Association Magnet hospital program has had a proven success in raising the standards of nursing practice and improving patient outcomes. Currently there are 85 organizations that are designated Magnet hospitals. Magnet facilities are characterized by strong administrative support, adequate nurse staffing, strong communication, nurse autonomy, better control, and a vital focus on the patient and their family. A growing body of research indicates that this program is making a positive difference for nurses, patients, and the hospitals as a whole. Research is proving that through this program, nurses are having increased satisfaction as well as increased perceptions of productivity and the quality of care given. Studies also indicate that these facilities have lower incidence of needle stick injuries, lower burn out rates, and double the retention of non-Magnet facilities. By adopting the characteristics of Magnet hospitals, facilities will be able to create a culture of retention that empowers and is respectful of nursing staff. Strengthening the Infrastructure In 2002 the Nursing Reinvestment Act was signed by President Bush to address the problem of our nation’s nursing shortage. This initiative was intended to promote people to enter and remain in nursing careers, thus reducing the growing shortage. The law establishes scholarships, loan repayments, public service announcements, retention grants, career ladders, and grants for nursing faculty. Many statewide initiatives are underway to address this issue as well. In Pennsylvania, six new nursing education initiatives have been announced to address faculty shortage by encouraging current nurses to return to school, earn graduate degrees, and teach the next generation of nurses. Illinois is unveiling a plan to provide faculty scholarships and grants to nursing schools in order to expand student enrollment. California, whose nursing programs currently have wait lists over three years, is trying to expand nursing education through a $90 million initiative.

Elasticity of Demand Practice Problem

In microeconomics, the elasticity of demand refers to the measure of how sensitive the demand for a good is to shifts in other economic variables. In practice, elasticity is particularly important in modeling the potential change in demand due to factors like changes in the goods price. Despite its importance, it is one of the most misunderstood concepts. To get a better grasp on the elasticity of demand in practice, lets take a look at a practice problem. Before trying to tackle this question, youll want to refer to the following introductory articles to ensure your understanding of the underlying concepts:  a beginners guide to elasticity and using calculus to calculate elasticities. Elasticity Practice Problem This practice problem has three parts: a, b, and c. Lets read through the prompt and questions. Q: The weekly demand function for butter in the province of Quebec is Qd 20000 - 500Px 25M 250Py, where Qd is quantity in kilograms purchased per week, P is price per kg in dollars, M is the average annual income of a Quebec consumer in thousands of dollar, and Py is the price of a kg of margarine. Assume that M 20, Py $2, and the weekly supply function is such that the equilibrium price of one kilogram of butter is $14. a. Calculate the cross-price elasticity of the demand for butter (i.e. in response to changes in the price of margarine) at the equilibrium. What does this number mean? Is the sign important? b. Calculate the income elasticity of demand for butter at the equilibrium. c. Calculate the price elasticity of demand for butter at the equilibrium. What can we say about the demand for butter at this price-point? What significance does this fact hold for suppliers of butter? Gathering the Information and Solving for Q Whenever I work on a question such as the one above, I first like to tabulate all of the relevant information at my disposal. From the question we know that:M 20 (in thousands)Py 2Px 14Q 20000 - 500*Px 25*M 250*PyWith this information, we can substitute and calculate for Q:Q 20000 - 500*Px 25*M 250*PyQ 20000 - 500*14 25*20 250*2Q 20000 - 7000 500 500Q 14000Having solved for Q, we can now add this information to our table:M 20 (in thousands)Py 2Px 14Q 14000Q 20000 - 500*Px 25*M 250*PyNext, well answer a  practice problem. Elasticity Practice Problem: Part A Explained a. Calculate the cross-price elasticity of the demand for butter (i.e. in response to changes in the price of margarine) at the equilibrium. What does this number mean? Is the sign important? So far, we know that:M 20 (in thousands)Py 2Px 14Q 14000Q 20000 - 500*Px 25*M 250*PyAfter reading using calculus to calculate cross-price elasticity of demand, we see that we can calculate any elasticity by the formula: Elasticity of Z With Respect to Y (dZ / dY)*(Y/Z) In the case of cross-price elasticity of demand, we are interested in the elasticity of quantity demand with respect to the other firms price P. Thus we can use the following equation: Cross-price elasticity of demand (dQ / dPy)*(Py/Q) In order to use this equation, we must have quantity alone on the left-hand side, and the right-hand side is some function of the other firms price. That is the case in our demand equation of Q 20000 - 500*Px 25*M 250*Py. Thus we differentiate with respect to P and get: dQ/dPy 250 So we substitute dQ/dPy 250 and Q 20000 - 500*Px 25*M 250*Py into our cross-price elasticity of demand equation: Cross-price elasticity of demand (dQ / dPy)*(Py/Q)Cross-price elasticity of demand (250*Py)/(20000 - 500*Px 25*M 250*Py) Were interested in finding what the cross-price elasticity of demand is at M 20, Py 2, Px 14, so we substitute these into our cross-price elasticity of demand equation: Cross-price elasticity of demand (250*Py)/(20000 - 500*Px 25*M 250*Py)Cross-price elasticity of demand (250*2)/(14000)Cross-price elasticity of demand 500/14000Cross-price elasticity of demand 0.0357 Thus our cross-price elasticity of demand is 0.0357. Since it is greater than 0, we say that goods are substitutes (if it were negative, then the goods would be complements). The number indicates that when the price of margarine goes up 1%, the demand for butter goes up around 0.0357%. Well answer part b of the practice problem on the next page. Elasticity Practice Problem: Part B Explained b. Calculate the income elasticity of demand for butter at the equilibrium. We know that:M 20 (in thousands)Py 2Px 14Q 14000Q 20000 - 500*Px 25*M 250*PyAfter reading  using calculus to calculate income elasticity of demand, we see that (using M for income rather than I as in the original article), we can calculate any elasticity by the formula: Elasticity of Z With Respect to Y (dZ / dY)*(Y/Z) In the case of income elasticity of demand, we are interested in the elasticity of quantity demand with respect to income. Thus we can use the following equation: Price Elasticity of Income: (dQ / dM)*(M/Q) In order to use this equation, we must have quantity alone on the left-hand side, and the right-hand side is some function of income. That is the case in our demand equation of Q 20000 - 500*Px 25*M 250*Py. Thus we differentiate with respect to M and get: dQ/dM 25 So we substitute dQ/dM 25 and Q 20000 - 500*Px 25*M 250*Py into our price elasticity of income equation: Income elasticity of demand: (dQ / dM)*(M/Q)Income elasticity of demand: (25)*(20/14000)Income elasticity of demand: 0.0357Thus our income elasticity of demand is 0.0357. Since it is greater than 0, we say that goods are substitutes. Next, well answer part c of the practice problem on the last page. Elasticity Practice Problem: Part C Explained c. Calculate the price elasticity of demand for butter at the equilibrium. What can we say about the demand for butter at this price-point? What significance does this fact hold for suppliers of butter? We know that:M 20 (in thousands)Py 2Px 14Q 14000Q 20000 - 500*Px 25*M 250*PyOnce again, from reading  using calculus to calculate price elasticity of demand, we know that we can calculate any elasticity by the formula: Elasticity of Z With Respect to Y (dZ / dY)*(Y/Z) In the case of price elasticity of demand, we are interested in the elasticity of quantity demand with respect to price. Thus we can use the following equation: Price elasticity of demand: (dQ / dPx)*(Px/Q) Once again, in order to use this equation, we must have quantity alone on the left-hand side, and the right-hand side is some function of price. That is still the case in our demand equation of 20000 - 500*Px 25*M 250*Py. Thus we differentiate with respect to P and get: dQ/dPx -500 So we substitute dQ/dP -500, Px14, and Q 20000 - 500*Px 25*M 250*Py into our price elasticity of demand equation: Price elasticity of demand: (dQ / dPx)*(Px/Q)Price elasticity of demand: (-500)*(14/20000 - 500*Px 25*M 250*Py)Price elasticity of demand: (-500*14)/14000Price elasticity of demand: (-7000)/14000Price elasticity of demand: -0.5 Thus our price elasticity of demand is -0.5. Since it is less than 1 in absolute terms, we say that demand is price inelastic, which means that consumers are not very sensitive to price changes, so a price hike will lead to increased revenue for the industry.
