...Sample paper AQA AS Business Case study – Paper 2: Answers SAGA 1. price at flotation = 185 pence; price on 15/10/14 = 158 pence % change = 27p / 185p x 100 = a fall of 14.6%. 2. 33% is 20m so 20m/ X x 100 = 33% so X = 20m x 100 / 33 = 60,606,060. 3. If Saga can reduce its debt levels this would mean less interest costs and so higher profit. This could help the share price recover as investors could now expect to be paid more dividend. The article says that debt financing costs reduced Saga profits by over £20m. Alternatively the extra profit could be used by Saga and be reinvested into areas where Saga wants to grow (e.g. care homes). Funded by profit, an internal source of finance, future business growth could make the shares worth more so their price will rise and shareholders will hold an investment in Saga which is more valuable. 4. When demand is price elastic it means that changes in price have a more than proportionate impact on demand. If, e.g., Saga were to increase its insurance prices by 5% and the PED is -1.5, then demand will fall by 7.5% and there would be a fall in Saga insurance revenues. However, if Saga reduced prices by 10% then demand would rise by 15% and revenues would rise. Operating in markets where low price might be important (because people might not be fussy about who provides the insurance as long as there is cover), if Saga can offer competitive rates then it might be able to increase its market share. To be able to offer...

It serves as the Archimedean point where media practitioners and citizens are empowered to air out their concerns without undue fear, simply because this provision of the Bill of Rights (Article III) safeguards these said rights. This clause in the constitution carries with it the history of the Filipinos' fight for freedom.Originally asserted in the Malolos Constitution (approved on January 20, 1899) as "right to freelyexpress his ideas or opinions, orally or in writing, through the use of the press and other similar means", this fight for freedom has transcended through various epochs of Philippine history; carried on from one charter change to another; and pulled through every rise and fall of one administration to the next. However, laws governing the practice of mass media in the Philippines does not solely rest on the present Constitution; they are also contained in the numerous issuances of the Courts and the Philippine legislature.

...Introduction The chosen organisation for the purpose of this assignment is the England and Wales Cricket Board (hereafter ECB). The ECB is the governing body of cricket in both England and Wales and was created on the 1st January 1997, replacing the National Cricket Association and the Test and County Cricket Board. It has increasingly turned to commercial revenue generation to support its activities and raises revenue from the proceeds of broadcasting, sponsorship, the sale of merchandise and through the sale of tickets for International cricket fixtures hosted at venues throughout England and Wales. Hoult (2014) comments that as a result of new broadcasting deals and increasing profits, the ECB has faced increased pressure from County Clubs and the associated Test Match venues to alter its previous ticketing and test match venue selection policy. From 2017 ticketing costs and revenue will no longer be the sole responsibility of the Test venue and instead the venue and the ECB will share ticket revenue. The remainder of this essay will therefore focus on commercial revenue, notably the sale of England Team Test match tickets. It will introduce economic theories relevant to the sports market and will attempt to assess the usefulness of economic theory in analysing demand for these products. It will discuss the response made by the sport market to an increase in the price of these products and will examine strategies the ECB can use to increase its market share. ...

...Essay: Do you think that there has been any relaxation of state control over the Chinese media over the past couple of decades, or is there simply a cycle of tightening and loosening the state control on the media that does little to reduce the power of the government? (Give examples to support your answer) Since the establishment of People’s Republic of China (PRC) on 1st October 1949, the Chinese Communist Party (CCP) had a tight control on the Chinese media. Prior to the reform in 1979, all of the Chinese media outlets were controlled by the state. The number of media sources was strictly regulated, and the content, length and even format of newspaper had to adhere to the CCP guideline. (Hassid, 2008) The total control of Chinese media during the Mao era had a profound impact on flow of free information among Chinese people as the news providers were either funded directly by the state or indirectly through policy of forced subscription and cross subscription between publications. (Hassid, 2008) Even though there have been significant changes in the relationship between the Chinese government and the Chinese media ever since Deng Xiaoping’s reform from the late 1970s with the rise of local, provincial, and regional media organizations, as well as online media platforms, the Chinese government is still very much controlling the Chinese media and its centralized power. The Chinese media was once regarded as a singular entity during the time of “building socialist modernity”...

...defined as the number of deaths per 1000 of the population per year. The decrease in these rates has been due to a number of factors. One reason for the fall in the birth rate is as a result of the declining infant mortality rate (IMR). This has meant as a factor that because there are less infant deaths before their first birthday, there are a number of fewer children needing to be born as replacements for those that the parents have lost. The IMR in 1900 was 154 whereas this has fallen to just 4.4 in 2014. This decline in the IMR has been due to better awareness of nutrition and a vast improvement in the NHS care of post-natal mothers by setting up support clinics. But sociologists have argued that the trend to smaller families first happened in urbanised areas where the IMR remained quite high. Another main reason for the fall in the birth rate is the changes that have happened since 1900 to give a better position to women in society. The changing position of women has contributed to more women now choosing to have a career before children and with an easier access to divorce and family diversity being acknowledged Liberal Feminists have argued that now women have an increased choice and are a step closer to being free from patriarchal oppression. Feminist movements who were an influential figure in the early 1900s also gave rise to the awareness of contraception and medical intervention in the choice for women. Marie Stopes , a suffragist, especially raised awareness of contraceptives...

...the past 50 years, one would think that the percentage of the population who have achieved self-actualization would have increased. While there are no studies to ascertain whether this is or is not the case, there are a number of factors to be taken into consideration that act as barriers to self-actualization which I will now discuss. In the past 50 years, society in which we live has made a shift to being one that in largely concerned with materialism. As a result of this, from a young age individuals are becoming more and more materialistic and are focusing on obtaining the latest electrical gadgets, cars and footwear. The media plays a large part in this. Today even without leaving our house we are subjected to materialistic images on the television and in the newspaper, all of which subliminally affecting how we prioritise our needs. The media not only drives our desire for materialistic goods, but it also plays on our basic needs for ‘self esteem’ and ‘love and belonging, all of which is intrinsically linked. For many people, especially teenagers and adolescents, they believe that if they acquire these material goods then they will gain social acceptance from their peers, thus meeting their need for love and belonging. Similarly, for others who buy into the ideology of ‘retail therapy’ they feel the need to purchase material goods they have been sold through...

... changed quite dramatically since 748 AD (the first record of a newspaper in Beijing, China). From Johannes Gutenberg’s invention of the printing press in 1451 to dwindling circulation in 2010, the newspaper industry has experienced both impressive growth and steady decline. In the 1700s, market factors such as rising literacy and the development of postal services galvanized the distribution of newspapers. Growth continued in the 1800s with the rise of the middle class. In the early 1900s (i.e. before the advent of television), substantial adverting revenue allowed newspapers to become enormously profitable. However, in the late 1900s and early 2000s, the tides began to shift. The business...

...African American Stereotypes in Movies Media Research Methods CO 455 November 20, 2012 African American Stereotypes in Movies Introduction There once was a time when everyone expected the black man to be the first actor to die in every movie that possessed a black man in its cast. However, over time the assumption of the black man being the first to die has changed. Currently in the year 2012, there are progressively more movies in which black men portray leading roles. This change in black men as leading characters in movies is a welcome change. In the past, supporting or backup roles were considered the best role a black man could achieve. In this paper, the researcher will conduct information by means of content analysis. Content analysis is the most commonly used methodology because of its ability to measure human behavior, assuming that the verbal behavior is a form of behavior. This study will examine specific media products and define these products by determining smaller elements that complement these products. This document will address a wide view of concerns regarding the African American culture, and will provide assumptions on how this issue can be addressed in the future. The stereotype of African Americans in movies today, is the topic of this research paper. Why do African Americans face stereotypes in the media? Why do black actors and actresses have difficulty obtaining roles that are not stereotypical...

...Suddenly, waking up in the morning, trying to fall asleep or simply interacting with other people becomes one of the most difficult challenges. Depression can be cause by many things such as financial issues, relationship problems, family problems or an individual just may not be happy. Although, if this person uses their social imagination it may be a little easier for them to cope with their depression. Looking at their problems in a more general perspective helps them realize they are not alone and these are daily problems everyone faces. Sociologist C. Wright Mills quotes “The sociological imagination enables its possessor to understand the larger historical scene in terms of its meaning for the inner life and the external career of a variety of individuals.” (Chap 1 pg2). C. Wright Mills presumes the Sociological imagination was a helpful way for people to allay their suffering by looking at their problems as if they weren’t the only ones going though it. The sociological imagination helps us look into the history and relations between an individual and society. (chap1) Depression can drain all your energy it can impair ones ability to keep up with societies daily routines such as sleeping, eating, enjoying activities that were once pleasurable. Growing up in the late 90’s early 2000’s the rise in the use of technology has increased dramatically. Due to this many people have become more open rather on social media sites.
