UN Human Development Index (HDI)

The Human Development Index (commonly abbreviated HDI) is a summary of human development around the world and implies whether a country is developed, still developing, or underdeveloped based on factors such as life expectancy, education, literacy, gross domestic product per capita. The results of the HDI are published in the Human Development Report, which is commissioned by the United Nations Development Program (UNDP) and is written by scholars, those who study world development and members of the Human Development Report Office of the UNDP. According to the UNDP, human development is â€Å"about creating an environment in which people can develop their full potential and lead productive, creative lives in accord with their needs and interests. People are the real wealth of nations. Development is thus about expanding the choices people have to lead lives that they value.† Human Development Index Background The main motivation for the Human Development Report itself was a focus on only real income per capita as the basis for a country’s development and prosperity. The UNDP claimed that economic prosperity as shown with real income per capita was not the only factor in measuring human development because these numbers do not necessarily mean a country’s people as a whole are better off. Thus, the first Human Development Report used the HDI and examined such concepts as health and life expectancy, education, and work and leisure time. The Human Development Index Today The second dimension measured in the HDI is a country’s overall knowledge level as measured by the adult literacy rate combined with the gross enrollment ratios of students in primary school through the university level. The third and final dimension in the HDI is a country’s standard of living. Those with higher standards of living rank higher than those with lower standards of living. This dimension is measured with the gross domestic product per capita in purchasing power parity terms, based on United States dollars. In order to accurately calculate each of these dimensions for the HDI, a separate index is calculated for each of them based on the raw data gathered during studies. The raw data is then put into a formula with minimum and maximum values to create an index. The HDI for each country is then calculated as an average of the three indices which include the life expectancy index, the gross enrollment index, and the gross domestic product. 2011 Human Development Report 2011 Human Development report 1) Norway2) Australia3) United States4) Netherlands5) Germany The category of â€Å"Very High Human Development includes places like Bahrain, Israel, Estonia, and Poland. Countries with â€Å"High Human Development† are next and include Armenia, the Ukraine, and Azerbaijan. There is a category called Medium Human Development which includes Jordan, Honduras, and South Africa. Finally, countries with â€Å"Low Human Development† include such places as Togo, Malawi, and Benin. Criticisms of the Human Development Index Despite these criticisms, the HDI continues to be used today and is important because it consistently draws the attention of governments, corporations, and international organizations to portions of development which focus on aspects other than income like health and education.

The Ideal Style And Application Methods Of Leadership Essay

Change Management within this Organization Leadership is; expected, valued, respected and rewarded within this organization. This trait is specially selected for, and then systematically developed and honed at all levels, and at all positions within the organization. The ideal style and application methods of such leadership within this organization has evolved over the years. And, the organization now places a high premium on those individuals who can not only lead, but that can then readily follow as the situation dictates, who can compete and then later cooperate, and those who can best transition their applied leadership and management style; to best fit the situation and circumstances at hand, ensuring optimal results while inspiring excellence in performance. Rather than those who, for example, simply default to an autocratic and dictatorial leadership style. Autocratic and dictatorial leadership styles were the norm for western armies as recent as World War I. The military historian Professor Gary Sheffield, on the BBC website, captures well the sentiment and perspective shared by many historians who’s common †¦stereotype is that the ordinary soldiers were lions led by donkeys – the donkeys being incompetent, uncaring generals, responsible for thousands of unnecessary deaths during WWI.

The Inequalities Surrounding Indigenous Health Free Essays

The Inequalities Surrounding Australian Indigenous Health Inequality in health is one of the most controversial topics within Australian Health Care. Inequality in relation to health is defined as being â€Å"differences in health status or in the distribution of health determinants between different population groups† (World Health Organization, 2012). Within Australia inequality affects a wide range of population groups; however Indigenous Australians are most widely affected therefore this paper will focus on how inequality has impacted their health. We will write a custom essay sample on The Inequalities Surrounding Indigenous Health or any similar topic only for you Order Now Research shows that Australia’s Indigenous people suffer from a multitude of social and economic inequalities such as inadequate access to nutritious food and health care, being socially and economically ostracized, cultural barriers, discrimination, inadequate shelter and sanitation, and insufficient education (Commonwealth Grants Commission 2001, p. 58-60; Australian Human Rights Commission 2007), which all contribute to poor health physically, emotionally and spiritually. To gain a better understanding of the ill treatment of this population it is important to review Australian history and the affects on the individual and the community. Throughout history Indigenous Australians have suffered great inequality at the hands of white settlers. In 1788 the British colonialists arrived claiming the continent as their own without respect or consideration for its inhabitants. The inequality suffered by the Indigenous due to this lack of respect was brutal and executed with contempt, such as large scale massacres, assimilation of Indigenous children (known as the stolen generation), the banishment of entire communities, and a loss of land impacting on the hunter gatherer lifestyle etc. Australian Indigenous Health Info Net, 2011). Prior to the arrival of the British, â€Å"Indigenous Australians generally enjoyed better health †¦ than most people living in Europe† (Australian Indigenous Health Info Net, 2011), this could be directly due to the nomadic lifestyle and relatively small clans. According to the Australian Indigenous Health Info Net after the arrival of the British, Indigenous tribes were exposed to a n umber of diseases such as pertussis, small pox, tuberculosis, venereal diseases, measles, scarlet fever and Influenza. Having had no previous exposure to such afflictions Indigenous Australians endured a significant loss of life and their social structure was severely disrupted (2011). Throughout history inaccessibility of conventional health services and insufficient distribution of health frameworks in some Indigenous communities, has inevitably created a disadvantage to be as healthy as non-Indigenous Australians (Australian Human Rights Commission, 2007). Although society has advanced and is now bound by more equitable laws, large numbers of Indigenous Australians as individuals and as communities continue to suffer lower socioeconomic circumstances and health inequalities. This history of inequality, discrimination and overall mistreatment has not only had a prolific impact on the health and socioeconomic status of Indigenous individuals but it has contributed to an increase in detrimental social conditions and a lack of faith in their Non-Indigenous counterparts, the Government and the Australian Health Care System. Isaacs, Pyett, Oakley-Brown, Gruis, and Waples-Crowe (2010) found that â€Å"A general lack of trust in mainstream services by the Indigenous community and previous experiences of racism and discrimination can draw individuals away from these services† (p. 78). VicHealth determines that the disadvantages of financial hardship has a considerable residual influence on health inequalities (2005, p. 1). Low income and financial hardship has commonly been linked with poor housing and hygiene. Disadvantaged Indigenous individuals are more than often sharing their dwellings and overcrowding is not unlikely. Overcrowding generally means that there is an unavoidable spread of disease (Commonwealth Grants Commission, 2001, p. 58-60), placing significant strain on an individual’s financial position, due to higher expenditure outcomes, affecting their ability to seek health treatment. Such strain can increase the individuals stress levels. The Australian Human Rights Commission points out that stress â€Å"can impact on the body’s immune system, circulatory system, and metabolic functions through a variety of hormonal pathways and is associated with a range of health problems, particularly diseases of the circulatory system (2007). Indigenous individuals are strongly identify with their community and work together to heal rather than exclusively. Therefore socio-economic disadvantages, intolerance and health inequalities that affect Indigenous individuals also have an impact on their communities. The introduction to the western/European way of living, loss of ancestral land, intolerance and the economic disadvantages that Indigenous Australians suffer fuels socially related conditions within their communities such as substance abuse, violence, increased degrees of infectious diseases and chronic diseases etc. ulminating in higher mortality rates than non-Indigenous Australians (Duckett Willcox, 2011, p. 34-35). Stephens, Porter, Nettleton and Willis (2006) state that â€Å"infectious disease burden persists for Indigenous communities with high rates of diseases such as tuberculosis, and inequality also exists in the prevalence of chronic disease, including diabetes and heart disease† (p. 2022). Statisti cs show mortality for most age groups of the Indigenous population is twice that of non-indigenous people. The highest rate of mortality of Indigenous people is six times that of non-Indigenous Australians, this mortality is encountered by both males and females aged between 35-44 years of age (Duckett Willcox, 2011, p. 33). Consistency of low socioeconomic position in Indigenous communities is a causality of ill health which exacerbates Indigenous people’s disparity, contributing a continuum of disparity and ill health among generations (VicHealth, 2005, p. 3). These impacts of health inequality for Indigenous Australians on the Australian health system are varied. Hospitals and health services experience a higher influx of Indigenous patients compared to their counterparts (Australian Human Rights Commission, 2007). The Australian Institute of Health and Welfare maintains that the ratio of Indigenous patients in health care settings compared to non-Indigenous is about three to one. Indigenous people present with a plethora of health problems including cardiovascular disease, diabetes, substance and violence related injuries, mental illness etc. (2011). All of these health issues have a deep correlation with inequality. The high rates of patient intakes and health issues surrounding Indigenous people suggests they are not accessing health services and health education that encourages and aids in prevention. As mentioned earlier Isaacs et al (2010) stated that this is a direct impact of fear and trust related to racial discrimination (p. 78). Insufficient education may play a role in the inability to understand what services are available to them. An abundance of health services are available to urban Indigenous communities; however access to services for more remote communities poses much financial difficulty and stress. Financial stress has also impacted the health care system as funding continually needs expansion to support the outcomes of poor health inequalities for this population. In 2006-2007 â€Å"Indigenous health care expenditure accounted for 3. 3% of national expenditure† (Australian Institute of Health and Welfare, 2011). The Australian Institute of Health and Welfare states that this is only slightly higher than what is allocated to services accessed by Non-Indigenous Australians, even though Indigenous people suffer a higher burden of disease (2011). It is evidential that more services are required to create preventative outcomes and to relieve financial burden across the board. Considering Indigenous people generally work as a community rather than as individuals (being that they are clan affiliated) perhaps it would be more beneficial for the community as a whole to address what improvements need to be made to better suit their cultural beliefs. Freemantle, Officer, McAullay and Anderson (2007) acknowledge that Indigenous communities who oversee attainable and adaptable services have consistent, convincing health improvements (p. ). Community leaders should work cohesively with local and state governments to create more holistic approaches toward gaining effective health outcomes. This may mean making the choice to take a leap of faith in the health care system and the government that has primarily been responsible for the mistreatment of Indigenous peoples. In addition the government at a national level is cohesively strategiz ing to improve life for Indigenous people. The Council of Australian Governments (COAG) has agreed upon a strategy developed to ‘Close the Gap’. Closing the Gap is a commitment by all Australian governments to improve the lives of Indigenous Australians, and in particular provide a better future for Indigenous children† (Department of Families, Housing, Community Services and Indigenous Affairs, 2009). State health departments such as VicHealth are also aiming to create improved health equality by enhancing awareness across all sectors, engaging in promotion to decrease health inequalities, establishing schemes that address health inequalities etc. (2005, p. ). Compared to the global community, Australian life expectancy and morbidity rates for Indigenous people have been found to be greater than that of other developed communities such as New Zealand, Canada and the USA (Freemantle et al. 2007, p. 2). The Freemantle et al. research (2007) revealed that Australian Indigenous people had an inferior life expectancy with males living approximately 56 years and females 63 years. In comparison, Canada’s Indigenous males lived approximately 68. 9 years and females 76. 6 years. In addition, the discrepancy in life expectancy between Australia’s Indigenous population and their non-Indigenous counterparts is marginally greater than that of other developed nations, with non-Indigenous Australians life expectancy at 76. 6 years for males and 82 years for females. In relation to morbidity, compared to the USA Australian Indigenous people experience an increased rate of illness such as diabetes at 85. 4, while the American Indigenous people only experience a rate of diabetes at 36. 2 (p. 26-28). It is evidential that Australian Indigenous populations suffer higher rates of health inequalities compared to other developed countries; this may be proof that Australia is not doing enough to bridge the gap. However it must be acknowledged that underdeveloped nations experience much lower rates of life expectancy and greater rates of illness, than developed nations. In conclusion it is suffice to say that since white settlement, Indigenous Australians as individuals and communities have suffered great health inequalities, due to racial discrimination and low socio-economic disadvantages. Although the Australian government and the health care systems are working towards amending these health inequalities, working cohesively with Indigenous communities will increase positive outcomes. Evidence shows that more effective action needs to be committed to and enforced. References Australian Government. (2001). Commonwealth grants commission: Indigenous funding inquiry.

Infection Control in Hospital Patients-Free-Samples for Students

Question: Discuss about the Infection Control in Hospital. Answer: Introduction Infection controlrefers to the discipline that is concerned with management and prevention healthcare associated or nosocomial infections in hospital settings. It is an essential topic in nursing owing to the fact that it forms the foundation of healthcare services, which aims to improve health and wellbeing of all patients. Infection control is selected as the research topic due to the fact that it is imperative topublic healthpractice (Krein et al. 2012). Its forms the major component of all kinds of invasive procedures that are administered upon patients in healthcare settings. Thus, infection control has two major implications in nursing practice (Rosenthal et al. 2012). While environmental disinfection will help in effectively controlling outbreak of an epidemic, it will also prevent spread of the infection by identifying exposure of all patients and healthcare staff to contagious infection. Further benefit is associated with the fact that the practice will remain in good standi ng with the standards and codes of nursing practice and will also help in increasing awareness on maintaining hygiene (Tacconelli et al. 2014). Reasons for undertaking research- The research activity has been undertaken on the aforementioned topic of infection control due to the fact that it is the primary objective of nurses in preventing the spread of pathogens such as, bacteria and viruses. It is essential in order to maintain a safe hospital environment for all patients. Reducing the risk of spread of pathogens will help in lowering rates of hospital acquired infections and will also ensure delivery of appropriate nursing practices. In addition, most sick and disabled people are cared for at hospitals in confined spaces. This increases their likelihood of getting affected with several microorganisms (CDC 2012). Therefore, it is essential to control the spread of infections. Furthermore, the research will also help in strengthening and increasing my awareness on demonstration of adequate nursing standards, thereby enhancing my clinical expertise and improving professional development. The research will also help in compar ing the effectiveness of traditional use of soap and water with chlorhexidine impregnated washcloths, thereby facilitating an easy understanding of the infection control practice that should be implemented in nursing practice (Rosenthal et al. 2013). It will also help in improving the nursing competencies through an exhaustive analysis of relevant literature, thereby assisting nursing workflow. Research question/hypothesis- The research question on which this research activity will be conducted is as follows: Does use of chlorhexidine washcloths reduce nosocomial infections? This research question will act as answerable inquiry that will facilitate addressing specific issue related to infection control in hospital patients. Research objective- It aims to evaluate the effectiveness of bathing using chlorhexidine washcloths in preventing hospital acquired infections. It will also compare the effects of proposed intervention with traditional infection control methods. This will further assist healthcare professionals such as, nursing staff in implementing the findings in future practice, thereby lowering rates of infection and improving the overall health and wellbeing of clients. Another discipline that can be correlated to this research activity is patient safety. This discipline emphasizes on safety of patients in healthcare settings through adoption of appropriate prevention strategies that are formulated with the aim of reducing medical errors (Borer et al. 2012). Thus, patient safety helps in eliminating chances of adverse patient outcomes. It encompasses reporting and analysis of all kinds of errors that might violate patient rights and predispose them to health hazards. Thus, in addition to nursing, the research activity will also enhance the arena of patient safety. Sources- Two sources that will be utilized to gather information on relevant articles related to infection control are as follows: PubMed- https://www.ncbi.nlm.nih.gov/pubmed/ Cochrane Library- https://www.cochranelibrary.com/ Methods of gathering information- Information will be gathered by searching relevant articles from the aforementioned sources. The research question is kept comprehensive and specific. The study will focus on using specific key terms or search terms that will help in retrieving articles that are relevant to the research question. Key search terms such as, infection control, infection prevention, hygiene, hospital infection, nosocomial, chlorhexidine, washcloth will be used in combination with several boolean operators namely, AND, OR, and NOT. Use of these operators will help in excluding articles that have been unpublished or are not relevant to the topic of interest. Systematic reviews will be used to collect information on use of chlorhexidine due to the fact that they contain exhaustive analysis of a wide range of studies and help in formulating answers to the proposed question in a structured format. Using systematic reviews in place of any other method will help in sysnthesising all available evidences on the particular question and will help us determine how effective the proposed intervention is. Systematic approach- Huang et al. (2016) conducted a systematic review that aimed to investigate effectiveness of daily chlorhexidine bathing in preventing nosocomial infections among ICU patients. Owing to the fact that healthcare associated infections are found to increase the length of hospitalization among critically ill patients and also increase associated medical costs, selection of this systematic review was a correct approach in retrieving information. It included articles extracted from EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials. It included 3 RCTs and 12 quasi-experimental studies, the primary outcomes of which were associated with rates of catheter linked bloodstream infections, urinary tract infections, and pneumonia. Results from most articles included in the review indicated that use of chlorhexidine in daily bathing helped in significantly reducing HAI among patients. Daily bathing in CHG was also found to lower mortality rates and occurren ce of adverse events. A randomized control trial conducted by Climo et al. (2013) evaluated the effectiveness of daily bathing using CHG impregnated washcloths on incidence of hospital infections and drug resistant organism acquisition. On conducting the trial among patient across 6 ICUs, findings of the trial showed a significant reduction in infection acquisition and rates of MRSA and VRE. A significant decrease was also observed in bloodstream associated infections during the intervention period. A quasi-experimental study was conducted among 3 cohorts to determine the effect of hospital wide CHG bathing on nosocomial infections. Upon administration of CHG bathing in form of showers or bed basin bath, the rate of HAI was monitored. Findings suggested that adherence to CHG bathing was more in adult patients in ICU. Furthermore, a significant decrease was observed in the infection rates during the intervention period, which was succeeded by increase in the washout period. Thus, implementation of chlorhexidine did not show any adverse effects on patient health. Analysis of the survey responses suggested that most nurses were capable of successfully implementing standardized bathing protocol (Rupp et al. 2012). A before-and-after study was conducted to describe the impact of CHG impregnated washcloths on VRE colonization. The study involved administration of the intervention on patients in the hematology and oncology ward and the incidence of VRE was determined. Significant decrease was observed in the rate of VRE acquisition during intervention, on comparison with baseline period. Roommates of patients with such infections were found at an increased risk of acquiring such infections (Bass et al. 2013). The systematic review is particularly relevant for this research activity due to the fact that it will facilitate understanding of the safety of chlorhexidine treatment, through an exhaustive analysis of the included research articles. It will also provide more generalizability of the findings and will help in implementation of the findings in actual practice. Conclusion Thus, it can be concluded that hospital acquired infections occur due to prevalence of bacterial, viral and fungal pathogens. These infections are most commonly found in intensive care units where patients are being treated for serious, life-threatening diseases. Based on the findings of the articles analysed, it can be stated that use of chlorhexidine washcloths can be implemented by infection control nurses in order to promote antisepsis. It will also prevent bacterial colonization, thereby eliminating infection. Thus, it has broad clinical application in healthcare setting and can be used as an effective and safe skin-prepping agent. Impact- In order to reduce transmission of infection among critically ill patients, the nurses should put on gloves and masks for protection (Page et al. 2013). They should take precautionary steps for washing their skin after handling CHG. Eyes of the patients as well as nurses should be rinsed cautiously on contact with CHG (Loveday et al. 2014). Use- The collected information can be used in workplace by showing compliance to specific guidelines framed by the hospital authorities. Patients will be regularly monitored to identify those susceptible to infection and will be isolated before administration of CHG. It will also help in identifying the source of infection or colonization of pathogens. Thus, it can help in reducing rates of nosocomial infections in workplace (Barbier et al. 2013). Reflection- The research helped me search realize that infection control is a major priority for all healthcare professionals. I understood that it is the duty of all nursing staff to ensure that healthcare professionals should practice good infection control practices to prevent all kinds of risk factors that might increase infection rates. Thus, all employees in contact with patients are bound to adhere to infection control practices for preventing the spread of organisms. One major change is regular monitoring of all patients and immediately isolating the ones found at an increased risk of infection. Issues- There is a need to conduct further research on effectiveness of other washcloths impregnated with herbal agents such as, bamboo for preventing infection (Yasin, Liu and Yao 2013). This will help patients who are cared for at their homes, where there is less availability of chlorhexidine washcloths References Barbier, F., Andremont, A., Wolff, M. and Bouadma, L., 2013.

A film comparison between emma and clueless

A film comparison between emma and clueless Jane Austen's early nineteenth century novel, Emma spawned two well-known films from the mid-nineties. These are of course Emma, directed by Douglas McGrath and Clueless, written and directed by Amy Heckerling. While Emma is a direct adaptation of the novel, Clueless was merely inspired by its themes and messages. Furthermore, Emma aspires to successfully present the novel in celluloid and entertain a female, adult audience whilst introducing Jane Austen to a new generation. Conversely, Clueless aims to transport the themes and morals presented within the novel into a modern context that is relatable to the youth of today. Despite these differing objectives the films are similar in terms of storyline, theme and characterisationSuperficially, Emma and Clueless are tales of love told from the perspective of 'the match-maker,' however beneath this veneer lie stories about young women learning humility in the face of their own willful ignorance. In both stories the heroine misjudges not just Mr/Elton's affections, but also the extent of a second eligible man's affections for them.Jane Austen lived here, in Chawton, during her fin...Cher and Emma even misjudge their own feelings towards a brother figure: Mr Knightly in Emma, and Josh in Clueless. As a result of their mistakes, both undergo a 'spiritual makeover' and rethink their opinions of themselves and the things into which they put their time and energy. A more blatant connection in the plot occurs when Emma paints a picture of Harriet for Mr Elton to hang up in his house. The equivalent to this in Clueless would be when Cher takes a picture of Tai for Elton to pin up in his locker. In both films the portrait is hung up not because of the subject but because of who created the image. Indeed, the films share similar storylines, yet they are set in vastly different environments.Emma is...

Differences between IFRS and AAIOFI standards Term Paper

Differences between IFRS and AAIOFI standards - Term Paper Example The development of the international accounting standards and its acceptance would help in reducing the compliance costs and in the process would develop consistency in the quality of the audit. (IFRS in your pocket 2005, p. 2) What are IFRS standards? The International Financial Reporting Standards (IFRS) have been enforced by International Accounting Standards Committee for the better understanding by the equity investors, the lenders and anyone else who uses the information. The world securities regulators have been recommended by the International Organization of Securities Commission to allow the foreign users to use IFRS in making financial statements for the cross border offerings and listings. The uses of IFRSs have been made obligatory in the consolidated statements of the listed Europe companies from the year 2005. It has also been reported that many countries have started replacing their national GAAP by IFRSs in their domestic companies in comparison with the other nation s which are adopting policies to approve IFRSs either verbatim or in the exact manner as their national standards. The IASB and the US counterpart of it, the Financial Accounting Standard Boards, have taken up a comprehensive agenda to converge the IFRSs and the US GAAP as much as possible over the next several years. A convergence project has also been initiated with Japan. The pre-requisites of the global business is a global capital market which is ensured by superior governance, better-quality laws and a set of internationally accepted accounting standards. The IFRSs standards have been largely accepted around the world. The Standards of IFRS 1. The initial acceptance of the International Financial Reporting standards. The objective of the standard was to lay down the process when the IFRSs are being newly adopted by any organization while drafting its financial statements for common purpose. The statement includes an overview of the financial statements for the first time entit ies and they should draft their accounting policies according to the IFRSs which have been enforced from 31st December, 2005. The organization is needed to frame its financial statements at least for the years 2005 and 2004 and also should reaffirm the opening balance sheet. As IAS 1 requires the comparative financial data of the previous one year minimum the opening balance sheet that will be produced should be of January 1, 2004 if not earlier than that. If the entity adopts the standards on 31st December 2005 and produce selected portion of the financial data on an IFRS basis for the period before 2004 along with its financial statements for the year 2004 and 2005, that would not change the fact that the opening balance sheet according to the IFRSs standards will be of 1st January 2004. (p. 57) 2. Share Based Statement The objective of the standard is to lay down for the transaction which involves the receiving or acquiring of goods or services by the entity either as a â€Å"co nsideration for its equity instruments or by incurring liabilities for amount based on the price of the entity’s shares or other equity instruments of the entity†. (p. 58) The Standard specifies the mandatory recognition of the entire share based payments in the financial statements on the basis of a fair value measurement. It also specifies the recognition of any goods and

Design ethics of pratice - Essay Example This paper highlights the competing values that have played out the contemporary companies that advertise their products. In 1996, Calvin Klein also known as CK made remarkably advertisements in the televisions, and magazine, the advert was in promotion of their jeans products. The advert drew criticism from all quarter of the world given the kind of pictures that were used in the adverts, the company used picture of some young people that were posed in a provocative manner- the young people were actually nude. They made this pictures be aired in televisions attracting huge uproar of complains and castigation. Notwithstanding, CK has had a fair share of controversies surrounding their advertisement criteria, in 1980's they aired ads that saw a 15-year-old actress Brooke Shields saying, ‘Nothing comes between me and my Calvin’ (Berry 2000, p. 41). The advert becomes controversial in the sense that it is mostly concentrated around the actress private parts; this has raised eyebrows and attracted condemnation from the public. The focus of the advert on the specific parts of the actress body was perceived unethical and resulted into complains that were given then. The company staged a series of ads in 1996 that was aimed at promoting the CK jeans wear by engaging models who posed in suggestive ways. The ads began in early July and ran in several magazines that were read by those considered to be under aged. For instance, during the period of advertisement in the magazines, young girls aged 12 years got access to the pictures that were considered unethical. Many publishers, in this relation claimed that the adverts that were used by CK then bordered pornography and should not have been aired to the public. Figure A shows one of the images taken from the ad of 1996 Figure A As can be seen in the pictures, the ad exhibited a photographer shooting a young male and a female models in what appeared to be a wood-panelled basement. The shooting was coupled wit h a creepy, predator voice of the young lady asking the man who is half dressed some suggestive questions. The lady asked â€Å"Do you think you can rip off that shirt on your body?† the young man then responded and obliged to the young lady’s question by removing the shirt. She continued and commented â€Å"That's a nice body, do you work out?† at this time, the camera used in the shoot out was concentrating in the young lady’s private parts. Parent groups and children welfare organizations raised questions about the age of the participants in the campaign, many of whom looked to be under 18.  These organizations felt that the children were being coerced to appear in the shoot out under the pretence that they will be normal shooting but the whole issue changes to the nude shooting that is used for CK adverts. According to the organizations, adverts should be moderated even if they have to be suggestive about sex, the one that was used by CK went overbo ard since the shoot out was done in an environment that depicted pornography. The belief that the advert bordered on pornography is also accentuated by the fact that one can hear the photographer instructing the actress on how to look like a pornographic actress.   This public complain was taken to the department of justice and investigations were warranted to look into the possibility of the advert having violated child phonographic

The Goophered Grapevine. Charles Chestnutt Essay

The Goophered Grapevine. Charles Chestnutt - Essay Example The term defines the way African Americans see themselves as individuals and as a group, but not just through their own eyes. They see themselves through the lens of the Other, the dominant culture. Du Bois says it is "always looking at one's self through the eyes of others, of measuring one's soul by the tape of a world that looks on in amused contempt and pity" (Du Bois). This produces what Du Bois calls a "twoness,--an American, a Negro; two souls, two thoughts, two unreconciled strivings; two warring ideals in one dark body† (Du Bois). Understandably, being constantly aware of others’ perception and confounding, exploiting, and denying that view causes conflict within a person. Sometimes action may not be exactly ethical like the actions of the characters in â€Å"The Goophered Grapevine.† The conflict within African Americans occurs because the white American disrespected, humiliated, and dehumanized them. â€Å"Double consciousness† describes the Afri can Americans’ desire to contribute and participate in all the country has to offer; yet knowing that the wealth denied them was gained by the sweat of the brow of their ancestors. African Americans want to be both black and American, true to their culture and their country. However, even after Emancipation, it took more effort with much less return. Some deterrent is always thrown into the path of African American advancement—segregation, bussing, prejudice, unemployment. Charles Chestnutt’s story illustrates this double consciousness which influences every contact black Americans have outside their own culture. The story’s structure reveals the way the dominant culture views African Americans, narrated by the vineyard owner recounting Uncle Julius’s story. The vineyard owner shares it with the world seemingly without Uncle Julius’ permission. Of course, Uncle Julius asked the indulgence (read: permission) of the vineyard owner and his wife to share the story with them. â€Å"I wouldn' spec' fer you ter b'lieve me 'less you know all 'bout de fac's. But ef you en young miss dere doan' min' lis'n'in' ter a ole nigger run on a minute er two w'ile you er restin', I kin 'splain to yer how it all happen'" (Chestnutt). Uncle Julius prefaces his tale with his doubt that the vineyard owner will believe him, a result of the double consciousness. Uncle Julius expects his tale will be treated with derision and disbelief. Hearing the story, readers wonder why the slaves did not feel threatened enough by Dugal to avoid his vineyard, and the grapes continue to disappear. Apparently the slaves do not fall into Dugal’s traps. They know he cannot do much to them because if he punishes them too severely, the slaves may not work hard to harvest his grapes. Not only that, since they are the ones who do the work to make the grapes profitable, surely a few grapes are their due. This way the double consciousness serves them well. But it also backfires because Dugal knows what frightens them: the slaves believe the grapes are hexed. Dugal pays Aunt Peggy to hex them even though he does not believe they are truly bewitched. Otherwise, Dugal would not sell the scuppernong grapes and cause the death of anybody who ate them. He would be allowing people to die and killing off his own customers. Dugal’s purpose in â€Å"goophering† the grapes was that he knew the slaves believed in the conjuring. If they believed that the grapes were cursed, they would not eat them. The spell worked except for Henry who ate them without knowing of Aunt Peggy’s spell, which actually turned out fortunate for Dugal. Dugal thinks he is clever. The $10 he paid Aunt Peggy was a wise investment, especially since it provides income

Completed spins-offs of Hilton Grand Vacations (HGV) and Park Hotels and Resorts (PK) Hilton launched its newest brand the Tapestry Collection by Hilton. Description Hilton is one of the largest and fastest growing hospitality companies in the world, with a portfolio of 14 world class brands comprising over 4,900 properties with more than 800,000 rooms in 104 countries and regions. Hilton is committed to fulfilling its mission to be the worlds most hospitable company by delivering exceptional experiences at every hotel, to every guest, every time. Hilton was founded in 1919 by Conrad Hilton when he purchased his first hotel in Texas, Hiltons is the most recognized hotel brand in the world. Hiltons operate its business across three segments: ownership; management and franchise; and timeshare. Hiltons strategy focuses on providing service and cost models tailored to each hotel, reflecting size, business complexity, and market environment. Hilton provide appropriate levels of engagement depending on each hotels needs, by ensuring hotel owners are fully engaged in decision-making. This consolidated approach means Hilton maximize cost and scale effici encies, by sharing best practice, market and trend intelligence and ensuring appropriate affordability to each hotel. For example: Hilton refine its luxury brands to deliver products and service standards that are relevant to each region. Hiltons operations are mainly concentrated in the United States, however, it has its presence in the international markets such as in Europe, the Middle East and Africa, and in the Asia Pacific region. Operations Hilton operates its business across three segments namely; ownership, management and franchise, and timeshare. Ownership Hilton is one of the largest hotel owners in the world based on the number of rooms at the companys leased, owned and joint venture properties. Hiltons diverse global portfolio of owned and leased properties includes a number of prominent hotels in major cities such as New York City, San Francisco, London, Chicago, SÃ £o Paolo and Tokyo. Hiltons portfolio includes renowned hotels with significant underlying real estate value, by the end of 2016, the ownership segment had 141 hotels with 57,716 rooms. In recent years Hilton has expanded its hotel system less through real estate investment and more by increasing the number of management and franchise agreements the company has with third-party hotel owners. Hilton focuses on maximizing profitability and cost efficiency of all its portfolios by, reducing fixed costs and implementing new labor management practices and systems. For instance, Hilton has developed and executed strategic plans for each of its hotels to enhance the market po sition of each property. At many of its hotels Hilton has renovated guest rooms and public spaces and added or enhanced meeting and retail space to improve profitability. At certain of its hotels, Hilton is evaluating options for the adaptive reuse of all or a portion of the property to residential, retail or timeshare uses. Management and Franchise Hiltons management and franchise segment enables the company to manage timeshare properties and hotels and license its trademarks to franchisees. Hilton currently manages 4,734 hotels with 738,724 rooms. Therefore, this segment generates its revenue primarily from fees charged to homeowners, hotel owners and associations at timeshare properties. Hilton grows its management and franchise business by attracting owners to become a part of its system and participate in its brands and commercial services to support their hotel. On Hiltons part, these contracts require little or no capital investment to initiate and provide substantial return on investment for Hiltons. Hiltons primary management services consist of operating hotels under management contracts for the benefit of third parties, who either own or lease the hotels. Hilton earns an incentive fee based on gross operating profits and a management fee based on a percentage of the hotels gross revenue. For a fee Hilton franchise its trade, brand names, operating systems and service marks to hotel owners. Hilton does not directly participate in the daily operation or management of franchised hotels but its conducts periodic inspections to ensure that brand standards are maintained. Hilton approves certain aspects of development and the location for new construction of franchised hotels, in some cases, Hilton also provides the franchise with product improvement plans that must be completed in accordance with brand standards to remain in Hiltons hotel system. Timeshare Hiltons timeshare segment generates revenue from three primary sources: Resort Operations, Timeshare Sales, and Financing. Hilton market and sell timeshare interests owned by Hilton and third parties. The company sells timeshare intervals on behalf of third-party developers using the Hilton Grand Vacations brand. Through resort operations Hilton manages the Hilton Grand Vacations (HGV) Club, receiving annual dues, enrollment fees, and transaction fees from members. Hiltons also provides consumer financing, which includes interest income generated from the origination of consumer loans to customers to finance their purchase of timeshare intervals and revenue from servicing the loans. Strategy Since Hilton Worldwide was founded, the company has been among the top hospitality companies in the industry. In fact, after almost 100 years it is considered one of the largest and fastest growing corporations with the goal to deliver outstanding customer experiences and excellent operating performance. Hiltons business strategy is based on its service differentiation, the company distinguishes itself from its competitors by providing high quality service combining it with IT systems. According to Dudovki, (2016), Hilton has been focusing its strategy on digitalizing mobile services, booking channels, loyalty and data driven-personalization, and also improving guest experience and privacy. Enhanced service offering is at the forefront of Hilton strategy. In order to allocate more of customers travel spending to Hilton hotels, and consequently to enhance customer loyalty for the entire system of hotels and timeshare properties, the team created Hilton Honors Loyalty Program. The program rewards guests with points for each stay at any of Hiltons more than 4,900 hotels worldwide. Members can use the points earned for free hotel nights and other goods and services; moreover, it is possible to spend the points with 130 partners, among which car rental, rail, and airlines companies, credit card providers and others. The loyalty program contributed over $17 billion in terms of revenues as reported at the end of the year 2016. Another strategy employed by Hilton is premium pricing. Hilton utilizes the premium pricing policies for its upscale services and hotels. The pricing strategy is established to emphasize, among customers, the sense of status and luxury rather than the sense of stay and dining. Through the analysis of previous performance and strategies they provide to manage future profitability. For instance, they engage with sales teams for hotels with significant group/corporate business, to ensure corporate pricing structure is maximized throughout the RFP process. The management of Hilton believe every Hilton Worldwide property has its own unique strengths and challenges. As such they provide service and cost models tailored to each hotel, reflecting business complexity, size, and market environment. Hilton matches its service to the needs of the clients hotel, Hilton management believes that one size fits all. This consolidated approach means that Hilton maximize cost and scale efficiencies, rapidly sharing best practice, market and trend intelligence and ensuring appropriate affordability to each hotel. Hilton have focused on optimizing hotels market share and delivering market-beating revenue per available room (RevPAR) results. Hiltons team provides thorough analysis of previous performance and strategies to drive future profitability.

Reports by Financial Morningstar.com indicate that Hilton Worldwide is ranked among the largest player in the global hotel industry, Hilton and Marriott have the highest market share.

Hilton is growing quickly, as it has the highest global market share by room supply of approximately 4.7%. Hiltons operations are mainly concentrated in the United States, but it has started to increase its presence in the international market. Hilton has a higher market share of 9.3 % in the United States, it has a r elatively small share of 3% in other regions in the Middle East and Africa, 1.6 % in Europe, and 1.2 % in the Asia Pacific region. Hilton faces a strong competition as a hotel, resort, residential, and timeshare manager, franchisor, developer and owner. The hotel and lodging industry inspects several elements in terms of competition, such as the attractiveness of the facility, location, quality of accommodations, amenities, level of service, room rate, public and meeting spaces and other guest services, consistency of service, brand reputation and the ability to earn and redeem loyalty program points through a global system. Hilton principal competitors on a global scale are Marriott International, Accor S.A., Carlson Rezidor Group, MÃ ¶venpick Hotels and Resorts Hongkong and Shanghai Hotels, Hyatt Hotels Corporation, Intercontinental Hotel Group, and Wyndham Worldwide Corporation.

Experts project that revenues growth will decrease by 23.80% to 8.88 billion down from 11.66 billion in 2016. This expected decline in growth is not expected to translate in a reduction in overall EPS, as EPS, are expected to increase from $1.06 to $1.74. In fiscal 2017 the company plans to roll out its new simplified business model: A market leading fee-based business as over 90% of Hiltons revenue comes from franchise fee and management fee. This new business model is expected to generate significant revenues as the company continues to lead the industry in net unit growth without significant use of capital. Hilton intends to aggressively invest to drive revenues and manage risk. With the enhanced capabilities developed through the 354 hotels added in 2016 and the completion of a further 77,000 rooms. In addition, the company is expected to drive per unit growth due to the launch of its newest brand, Tapestry Collection by Hilton and extensive management contracts with large luxury hotels in countries such as China. However, general and administrative expense, non-recurring expenses and other expenses are projected to be flat compared to fiscal year 2016. Net profit is project to increase by 3.45% to 571,080 million. For the fiscal year ending December 2017, Hilton expects total revenue from continuing operations to increase by more than 20% up 88 million compared to the $18 million loss in 2016. Net unit growth is expected to be roughly 50,000 to 55,000 rooms as such system-wide RevPAR is projected to increase anywhere from 1 to 3 percent compared to 2016. For the fiscal year 2017 cash available for capital return and debt prepayments is projected to be between $900 million and $1 billion. Likewise, capital expenditures for the year, excluding amounts reimbursed by hotel owners, are estimated to be between $150 million and $200 million. Fiscal Year Ending December 2018 For the fiscal year ending December 2018, revenue are projected to increase by an average of 8.80 %, up to $9.67 billion, while earnings are expected to grow to an average of 2% to roughly $2.08 billion, showing positive prospects of continued growth. The earnings per shares are expected to show a corresponding increase from $1.74 to $2.08. Hilton is expected to drive leading investment returns to hotel owners, as hotel owners continue to invest in Hiltons system growth. Hilton is also expecting its market-leading growth to be amplified by its new brands that will bring new customers into its system and offers more opportunities for its existing customers to stay with the company. Capitalization and Other Asset and Liability Analysis During fiscal year 2016, in preparation for the spin-offs, Hilton entered into a series of financing transactions, of which the debt incurred by HGV and Park is the sole obligation of those entities after the spin-offs. Hilton entered into a $200 million senior secured term loan facility for HGV, the company also entered into a $750 million senior unsecured term loan facility for Park and issued two new commercial mortgage-backed securities (CMBS) loans for Park totaling $2 billion. The company also repaid $250 million on the senior secured term loan facility entered into in 2013. Finally the company borrowed $300 million on the revolving non-recourse timeshare financing receivables credit facility entered into in 2013 for HGV. Also during the fourth quarter of 2016, Hilton repaid the outstanding balance of $3,418 million on a CMBS loan entered into in 2013 and a $450 million mortgage loan, using net proceeds from 2016 borrowings and available cash. As of December 31, 2016, Hilton had $10.2 billion of long-term debt outstanding, of which $3.0 billion is transferred to Park and $0.5 billion is transferred to HGV in connection with the spin-offs. As of December 31, 2016, total cash and cash equivalents was $1,684 million, net receivables was $1.15 billion, inventory amounted to 541 million and other current assets was 176 million. In December 2016, Hilton paid a quarterly cash dividend of $0.07 per share on outstanding common shares, a total of $70 million, bringing total cash dividends paid in 2016 to $277 million. Hilton ended 2016 with property plant and equipment valued $8,930 million, goodwill of $5,822 million, intangible asset of $6,374 million, and other assets of $334 million the company also had deferred long term asset charge of 117 million. Hiltons total asset increased by 495 million to $26,211 million up from $25, 716 million in 2015. At the end of the 2016 the Hiltons had a working capital of $873 million, this indicates that the company has the ability to pay its short term liabilities. The current ratio is 1.33:1, which is also an indication of the companys ability to honor its short term obligations as they fall dues. Hiltons has $2,684 in total current liabilities, $20,312 million in total liabilities and total stockholders equity of $5,899 million and decrease of 52 million over the same pe riod in 2015. Projections indicate that along with Hilton s new simplifies business model and the separation of the three companies, the current capitalization structure Hilton should be profitable without the need for excess borrowing.

Foucault, Consumerism, and Identity Essay -- Philosophy

Foucault, Consumerism, and Identity Michel Foucault presents those revolutionary sorts of analyses that are rich not only for their content but for their implications and novel methodological approach. Just beyond the surface of his works lies such philosophical wealth that one can be overwhelmed by considerations of which vein to mine first, and what to make of the elements therefrom extracted. I’ve broken earth in several attractive sites this last week. Some, it seemed, hid their treasures too deep for the scope of this excavation. Some presented me with granite barriers which I do not yet have the tools to penetrate. At other sites, the earth gave way easily and I made great progress, only to be flooded out. Finally, at the fifteenth hour, I have struck something shiny. I wish to use Foucault’s accounts of socialisation, categorisation, and discipline, as the background for my analysis of a modern entity I call the â€Å"identity package.† I will define this concept and show how it fits into and is suggested by Foucault’s works. Following this I will deal briefly with supposed problems with Foucault’s account (or lack of an account) of subjectivity. Narrative gives coherence to a life. Particular episodes make sense in light of a uniting theme. The simplistic world view of the Middle Ages left people satisfied with fairly simple narratives. One knew their personal obligations and had a vague idea of how they fit into the systems of king and God. For the sovereign and the elite, their special status was confirmed in ceremony and artistic representations.1[1] The masses were unrepresented.

If you can’t beat them, label them. If it fits into our picture, it is ours. Put this way, it seems like we are imprisoned in a menacing matrix of metaphysical manipulation. However, as I have shown to be the case in pop culture, we are complicit in our captivity, in fact, all too willing to participate. 1[1]Michel Foucault, Discipline and Punish, tr.Alan Sheridan (New York: Vintage,1995) p.192 2[2]With an increase in bureaucracy came an increase in the importance of meticulous knowledge; with this, more power and a more distinct role for the researcher. 3[3]Modern advertising calls this â€Å"appeal to a certain demographic†. 4[4]Quoted in: Michael Clifford, Politcal Genealogy After Foucault, (New York: Routledge, 2001) p.99 Foucault, Consumerism, and Identity Essay -- Philosophy Foucault, Consumerism, and Identity Michel Foucault presents those revolutionary sorts of analyses that are rich not only for their content but for their implications and novel methodological approach.
