lieshod White Lies in Joseph Conrads Heart of Darkness Essay

Harmless exaggerations in Heart of Darkness   â â â In his novella Heart of Darkness (1899), Joseph Conrad through his essential storyteller, Marlow, reflects upon the indecencies of the human condition as he has encountered it in Africa and Europe. Seen from the point of view of Conrad's anonymous, target persona, the wrongs that Marlow experienced on the endeavor to the heart of obscurity, Kurtz's Inner Station on the banks of the snake-like Congo River, fall into two classifications: the negligible wrongdoings and inconsequential untruths that are basic spot, and the more prominent indecencies - the bizarre demonstrations society credits to crazy people. That the top notch of malefaction is associated with the second is outlined in the destruction of the story's auxiliary hero, the heartbreakingly misdirected and hubristic Mr. Kurtz. The European dreamer, accepting the lies of his Company and of the monetary colonialism that bolsters it, is caught off guard for the trial of character that the Congo forces, and capitula tes to the potential for the fiendish inactive inside each human awareness. Albeit various pundits (counting Johanna M. Smith, Peter Hyland, Herbert Klein, and Garrett Stewart) have caused to notice how Marlow's lie to the Intended advises the entire going before text and how that finishing scene with the Intended is associated with Marlow's underlying impression of Brussels as a whited catacomb (how fitting considering Belgian King Leopold II's deceptive barrier of his privately owned business' voracious abuse of the unbelievably named Congo Free State!), few have as of not long ago focussed on how the untruth influences the peruser's response to Marlow as the hero and storyteller of Conrad's Congo story.

Country analysis by 17 criteria Coursework Example | Topics and Well Written Essays - 750 words

Nation examination by 17 measures - Coursework Example The subsequent measure includes populace development. It tends to be examined that populace development in Argentina in 2013 remained at 0.90% whereby the development of Argentina populace made a more extensive market for UNIQLO items. The third standards involve the pace of joblessness in Argentina which remained at 7.50%. This implies higher joblessness rate oppressed UNIQLO to cause greater expense of work in the creation of Apparel and footwear industry (Encyclopedia, 2013). The forward segment standards involve pay dispersion which remained at a load of 46.30% in 2013. This implies as the pay conveyance increments among Argentina populace, more individuals could figure out how to purchase more clothing and footwear items and thus prompting an expansion in deals volume and gainfulness of UNIQLO Company (Arnold, 2011). The fifth measures involve Argentina populace socioeconomics of individuals between the ages of 15 to 64 years. It very well may be seen that the Argentina populace of individuals between the ages of 15-64 years expanded to 36897.8 whereby, a great many people at this age are monetarily autonomous and could bear to purchase UNQLO items. The 6th standards included urban populace which remained at 38517. An expansion in urban populace caused the interest of clothing item by urban populace to increment and subsequently making the deal units made by UNQLO Company to rise (International Monetary Fund, 2013). The seventh rule involves GDP (buying power equality); the Argentina populace in 2013 was 977983, the higher the GDP implies that the economy of Argentina was performing extraordinarily well which thusly made a more appeal for Apparel and footwear items. Under the eighth measures, the genuine development rate in Argentina remained at 3%. This implies the pace of development of GDP sta rting with one year then onto the next changed at the pace of 3%.

A 5-Year Columbia Students Take on On-Campus Housing COLUMBIA UNIVERSITY - SIPA Admissions Blog

A 5-Year Columbia Students Take on On-Campus Housing COLUMBIA UNIVERSITY - SIPA Admissions Blog Columbia’s location in Morningside Heights has, inevitably, shaped the neighborhood and its development. Over the recent years, the University has acquired a number of apartment buildings in the Morningside Heights vicinity, as well as in Harlem and the Manhattan Valley. In 2008, Columbia even acquired the Arbor, an admittedly nice apartment complex located in Riverdale. In the Bronx. (Don’t worry. Columbia offers a shuttle between the Arbor and both the Medical Center and Morningside Heights Campi. Pick your poison). Here’s a quick overview of the pros and cons of pursuing University Apartment Housing (UAH). Pros: It’s lowkey your best bet to stay close to campus. As noted before, Columbia has acquired, and continues to acquire, many apartment buildings in the Morningside Heights neighborhood. From my experience, SIPA students who pursue UAH are placed within a ten-minute walk to the International Affairs Building (IAB). In fact, SIPA students who live on 118th Street, between Amsterdam Avenue and Morningside Drive live right across IAB. Geographically speaking, students may be placed within the rectilinear domain bounded by 106th Street, Riverside Drive, 120th Street, and Frederick Douglass Boulevard/Central Park West. Path of least resistance. Perhaps the least work-intensive housing search can be found with UAH. If approved for UAH housing, students indicate their preferred price point, fill out a personality questionnaire, supply additional documentation, if needed, and done! Students are notified once they are placed, and the contact information of their potential roommate/suitemate is passed along. Upon arrival to campus, residents pay a visit to the UAH office (near the corner of 119th and Morningside) to sign a lease, and off they go! ‘Tis the season for sublets. School’s out for summer. But you’re not! UAH leases last for the entire duration of your student status. That means the apartment remains yours for the summer. If you’re interning or working in New York, you’re free to remain in your apartment. However, if your research sends you to Rome, or your internship places you in Iqaluit, you have the ability to sublet your apartment. The transient nature of the neighborhood means that someone would be more than happy to sublet your space. You’re also allowed to charge your subletter a premium, a rate higher than your rent, within reason. UAH has rules for that, but that discussion is best left for if you survive your first year a later time. Cons: UAH is not guaranteed. There is no way for the University to provide housing to its close to 20,000 postgraduates. That said, the various schools are allocated housing spaces; in turn, each school has its own process to determine which students received UAH. At SIPA, the Office of Student Affairs facilitates the UAH process, approving students throughout the summer. A number of factors can determine UAH eligibility including geographic distance away from New York, ability for a student to produce a credit report or credit history, among other things. If you pursue UAH, be sure to pursue other housing options until you receive an offer from UAH. UAH is (relatively) expensive. Going with UAH means paying for convenience. To quantify it, UAH offerings price between $850 to $1,500 per month, ($2,300 for couples/family spaces). Depending on the placement and contract, this price may or may not include utilities. The premium you pay relieves the stress of finding a place, using a broker, etc. That said, it is possible to find cheaper housing, with rooms in Morningside Heights going as low as $700, even $600. If you don’t mind venturing two or three stops north on the 1 line, you’ll surely get more for your money. Pro-tips: Make friends with a Columbia person who knows what’s up. They’ll be able to let you into various Facebook groups for housing (some pending activation of your UNI and email). Use OCHA! The Off-Campus Housing Assistance site can be a happy medium between an expensive UAH while still staying within the Columbia community. OCHA compiles a list of spaces posted by Columbia affiliates. Check them out! Bits of advice: Morningside Drive and Morningside Avenue are two different streets! Morningside Drive is the western border of Morningside Park, closer to campus. Morningside Avenue is the Park’s eastern border. Live where you want. Wanna live right next to school? That’s cool. All about the Chelsea life? That’s cool too. As bad gal Riri once said, “Ain’t got not time for no haters, just live your life.” Don’t mind a 30-40 min. bus ride? Check out Astoria in Queens. Great food, affordable places, and it’s an easy trip straight to the campus gates with the M60 Select Bus Service. Note from Admissions: To our incoming students, dont forget to register for the Housing Webinar tomorrow through the Welcome Portal!

At the start of the story, Sanger Rainsford is sailing south to hunt jaguars in the Amazon with a fellow hunter named Whitney. Rainsford is presented as heartless hunter, unconcerned about the life or feelings of his prey. In the middle of the night, Rainsford accidentally falls over the side of the yacht, but saves himself by swimming to the rocky shore of Ship-Trap Island. He discovers a large manor on a cliff. He knocks at the door and is welcomed by General Zaroff, a man of noble Cossack heritage who apparently lives on the island alone with his servant, a deaf-mute named Ivan. Zaroff explains that he is the ultimate hunter; he recieved his first gun at the age of 5, and has traveled the world and hunted every possible game animal. Now he has become so good at it that hes bored with his beloved pastime. After reaveling that he had to create a new animal, he indirectly states that he hunts men. He stocks his prey by tricking ships into wrecking near his island with misl eading navigation lights. When the surviving crew swim to his shores, he offers them a choice: they can be murdered by Ivan or choose to be hunted on the island by Zaroff. If they survive three days, he promises to set them free. Rainsford, who is immediately against the idea of hunting humans, tries to convince General Zaroff that hunting humans makes him a murder, not a hunter. This, of course, doesnt work and Zaroff offers Rainsford the choice: become prey, or die. Rainsford must set out to survive his three days as a game animal with only a sack of food and a knife.

Defy Gender Roles Free Essays

Christina G. Tarango Professor John ENGL 2342 April 21, 2013 Conform or Defy Gender roles in the society of the human race have always been that the women bare the children and take care of the home while the man is out working and bringing home the money to support his family. In certain societies this is still true and women do not have a say in what they do. We will write a custom essay sample on Defy Gender Roles or any similar topic only for you Order Now The role and identity of women in certain societies has been shaped and it is up to the woman under this conformity to conform or defy. The roles of women through the eyes of Marjane Satrapi as a young girl were quite â€Å"normal† for her. As a young girl she did not realize how different of a life style she was living from other young girls her age living in Iran. For example when she was six she says, â€Å"I wanted to be a Prophet because our maid did not eat with us. † Later on in the story she reveals that their maid named Mehri was eight years old when she had to leave her parents’ home to come to work for Marjane and her family. As a teenager, Mehri begins falling in love with the neighbors’ son. When Marjane’s family finds this out her father goes over to the boys home and tells him, â€Å"I know that Mehri pretends she is my daughter. In reality she is my maid. † Marjane does not understand why this cannot be. Her father says, â€Å"You must understand that their love was impossible, because in this country you must stay within your own social class. † Marjane begins to understand the whole concept of the Revolution and wants to demonstrate against it. Women in the novel conform to and also defy the expectations that are placed on them by going out and demonstrating during the Revolution but also confirm by wearing the veil. Over a broadcast a man declares, â€Å"Women’s hair emanates rays that excite men. That’s why women should cover their hair! If in fact it is really more civilized to go without the veil, then animals are more civilized than we are. † Marjane says, â€Å"In no time the way people dressed became an ideological sign. † Marjane says, â€Å"There were two different kinds of women, the fundamentalist woman and the modern woman. The fundamentalist woman covered her entire body with a black veil and only showed her face. The modern woman to show their opposition to the regime would still wear the veil but let a few strands of hair show and they would not cover their entire body either. They would wear pants, boots, and long coats. This was done in order to protect the women from all the po tential rapists, it was decreed that wearing the veil was obligatory. As a teenager she was stopped by the â€Å"Guardians of the Revolution. † These women were in place to arrest women who were improperly veiled. At the committee, they did not have to inform parents and they could detain girls for hours or even days. They could be whipped and in short anything could happen. This was quite traumatizing for Marjane however she did not tell her parents. Overall, the effects of these societal expectations on the psyche and development of Marjane as a child were very influenced by the revolution. Her parents tried their best to protect her from what was going on in their country. They tried to still give her all the liberties of that the Western children had. They did not want to take away from her childhood and wanted her to have the absolute best. They wanted her to have the best education and normal social life possible and free of terrorism. At the age of fourteen she was sent away to Austria where she would finish school and be a lot safer. WORKS CITED Satrapi, Marjane. Persepolis. United States: Pantheon Books, 2003. Print.

A review of economic growth and financial development literature

A review of economic growth and financial development literature Introduction It is the wish of every country to realize improved and sustainable economic growth and financial development in order to improve the living standards of the greatest majority among its citizenry. Improved economic and financial development is also central to a country’s ability to safeguard its survival in a world that is increasingly facing uncertainties, and unforeseeable risks.Advertising We will write a custom essay sample on A review of economic growth and financial development literature specifically for you for only $16.05 $11/page Learn More For these reasons, countries with visionary and development conscious leaders devise the most feasible economic blueprints that can enable them to reach greater heights of economic and financial success. In reality, a developmental state is a product of superior economic design; not accident, chance, or miracle. That is the bitter truth that the world’s poor and developing countriesâ⠂¬â„¢ leaders must embrace or condemn their countries to terminal economic and financial stagnation. This paper is a review of China’s economic growth and financial development. Economic growth Economic growth refers to a rise in the capacity of a country to generate goods and services, as compared from one period of its history to another (Barro Sala-i-Martin 2004, p.52). Economic growth is measured in real and nominal terms (Cypher Dietz 2008, p.33). Nominal terms include inflation while real terms are adjusted for inflation. Comparative studies of economic growth of different countries use GDP or GNP per capita because these variables take into account population differences between countries (Cypher Dietz 2008, p.33). Economic growth is normally attributed to technological advancement in a given society (Barro Sala-i-Martin 2004, p.52). United States is a prime example where enormous economic growth was realised following the introduction of the internet technology. I t is pertinent to note that, the growth of a country’s economy should not be seen in terms of an increase in its productive capacity only, but also as an improvement in the quality of life of its citizenry. In short, economic growth is a process through which a country’s wealth accumulates over an extended period. Therefore, economic growth can best be thought of as a process of transformation.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More According to Fitzgerald, a country’s long-term sustainable economic growth depends on its ability to increase its pace of accumulating physical and human capital, to use the resulting productive assets more efficiently and guarantee the reach of the entire population to these assets (2006, p.1). Financial Development Financial development refers to the â€Å"creation and expansion of instruments, institutions and markets that support a country’s investment and economic growth process† (Fitzgerald 2006, p.1; King Levine 1993, p.3). Banks and non-banking financial intermediaries such as stock markets and pension funds â€Å"play the role of translating household savings into enterprise investment, keep an eye on investments and distribute funds, as well as, to price and mitigate risks† (Fitzgerald 2006, p.1). Financial intermediation provides liquidity so that companies can operate the new capacities efficiently. Some economists hold that, financial development and economic growth are intimately related (Jeanneney et al 2008, p.3). Financial development influences a country’s economic growth, and helps to alleviate poverty because economic growth is a potential way of reducing poverty (Jeanneney et al 2008, p.3). Financial development helps alleviate poverty indirectly by motivating growth, and directly by enhancing transactions and enabling the poor to gain from financial services that raise their income, which facilitate their ability to undertake productive investments and other activities. Literature review on China’s economic growth and financial development The People’s Republic of China, popularly known as China is the most populous country with over 1.3 billion citizens. It is situated in East Asia (LaFleur 2003, P.3). It is a de jure one-party state ruled by the Communist Party of China (CPC) (LaFleur 2003, P.3). China is the third largest country by a total area and the second largest by land area (LaFleur 2003, p.3). During 1990s, the international community started to acknowledge that China’s economy is self-motivated and rapidly growing; therefore, its swift growth would continue for some time (Chow 1994, p.1). Today, china is one of the fastest growing economies internationally.Advertising We will write a custom essay sample on A review of economic growth and financial development literature specifically for you for only $16.05 $11/page Learn More Since 1978 when economic liberalization was introduced in China, China’s investment and export-led economy has grown 90 times bigger and is currently the fastest growing leading economy in the world (Wang et al 2007, p.85; Bramall 2009, p.464). According to the International Monetary Fund (IMF), during the period 2001-2010, China’s annual average GDP growth was 10.5 percent. This growth is anticipated to grow at 9.5 percent during the period 2011-2015 (Morrison 2011, p.2). Between 2007 and 2010; China’s economic growth rate was equivalent to all of the G7 countries put together (Morrison 2011, p.2). The link between economic growth and financial development has triggered a protracted debate from Smith to Schumpeter. According to research results over the years, financial development stimulates economic growth (Burzynska 2009, p.8). He argued that via the services that financial intermediaries bring about like mobilizing savings, containing risk and enhancing transactions technological and economic development is motivated (Burzynska 2009, p.8). For him, financial intermediaries facilitate technological innovation. Technological advancement according to Schumpeter is a process of continuous substitution of old production methods and goods with improved processes, services and goods by innovation and invention (Burzynska 2009, p.8). It has long been agreed amongst economists that financial institutions can enhance economic growth. For instance, Hicks put emphasis on capital formation, which he argued can be influenced by financial intermediaries by either changing savings rate or by redistributing savings among different capital generating technologies. There are, however, distinguished economists who oppose the view that financial developments stimulate economic growth. For example, for Robinson an economy in which enterprise is leading finance development follows (Robinson 1952, p.4 3). In other words, financial development takes place as an automatic response to rising varied financial needs. Other scholars were concerned that economists overemphasized the importance financial factor in economic growth (Lucas 1988, p.4).Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Financial intermediaries play six main roles. First, they pool household savings and make them available for lending (Burzynska 2009, p.9). Doing so reduces transaction costs for firms, as well as, households themselves. Secondly, financial intermediaries distribute savings and decide who gets loans (Burzynska 2009, p.9). Thirdly, financial institutions mitigate the overall risks of doing business by way of spreading investor’s funds among the diverse investment opportunities. Fourth, they produce liquidity. Fifth financial in situations facilitate trade by extending credit and guaranteeing payment (Burzynska 2009, p.9). Finally, they exert corporate control and monitoring of managers. A properly functioning financial system should ensure increased savings and investments which either via capital accumulation or technological change leads to rise in output and consequently economic growth (Burzynska 2009, p.9). China’s outstanding economic growth during the last two de cades has attracted considerable attention particularly from economists. Most empirical studies show that improvement in China’s productivity can account for an important portion of its striking growth (Morrison 2011, p.5). The source of China’s remarkable growth has two aspects namely domestic and international even though the two are intimately related. Since 1978, China backed free trade and gradually removed trade restrictions. The government transformed its policy of management of foreign trade by the Ministry of Foreign Trade and gave provincial governments a substantial autonomy in foreign trade and permitted private sector to take part in foreign trade (Morrison 2011, p.2; Chow 2005, p1). According to Chow (2005), during the period 1978 to 2002, total volume of exports and imports rose from $ 20.64 billion to a staggering $620.8 billion in 2002. This accounted for 65 % of china’s GDP and a growth rate of 35% annually (Chow 2005, p.1). Consequently, China became the third largest trading economy behind Germany and the United States. Presents Chinese exports are found all over the world. In the year 2001, China acquired World trade Organization membership. WTO pushed it to lower its tariffs for manufactured and agricultural products (Chow 2005, p.1; Bao et al 2006, p.181). The lowering of tariffs helped to increase competition among Chinese manufacturers and farmers and ended up providing inexpensive products for Chinese consumers. According to Chow (2005), foreign trade has boosted China’s economic growth in three aspects. International specialization, which occurs as each country produces the goods for which it has a comparative advantage in generating, has enabled China to procure more goods than by national production only (Chow 2005, p.1). Secondly, exports are a part of aggregate demand and rise in cumulative demand has helped China to raise its national output. Thirdly, trade in conjunction with foreign investment has b rought in modern technology and methods of management that has increased China’s productivity (Chow 2005, p.1). Another major cause of China’s economic growth was an increase in foreign investment, and domestic investments (Chow 2005, p.2; Morrison 2011, p.5; Zhang 1995, p.2). Even though available statistics show that private consumption fell from 49 percent of GDP in 1990 to 35 % in 2008, investment increased from 35% to 44 percent of GDP by the same date (Chow 2005, p.2). According to Clow (2005), flow of physical capital in the form of foreign direct Investment (FDI) has been exemplary in advancing China’s economic growth. After the introduction of the 1978 economic reforms, China’s foreign investment policies have positively changed. The 1978 economic reforms became a point of departure for China from seeing foreign investment as a form of exploitation by outsiders, to embracing it for purposes of China’s economic growth and development (Chow 2005, p.2; Morrison 2011, p.2). For instance, in 2001, an amount of FDI of $ 49.7 billion dollars was utilized while in 2003 $ 56.1 billion was utilized. Foreign investment has helped China’s economic growth through the provision of physical and financial capital, new technology and managerial skills to China (Chow 2005, p.2; Morrison 2011, p.5). Through the 1978 reforms the government also encouraged individual citizens to start their own businesses. Additionally, control of prices for various commodities by the state was gradually removed. Clow, however, points out that, foreign investment is not a basic economic factor in China’s outstanding economic growth, but only a vehicle boosting that growth (Chow 2005, p.2). Instead, there are three significant factors including availability of high quality human resources, which comprise properly trained and hardworking labourers, and creative entrepreneurs. Adequately properly functioning market institutions and chinaâ€⠄¢s standing as a late comer who can embrace new technology from the already developed countries (Chow 2005, p.3). These three fundamental factors have enabled china to create a centre of attention for foreign investors. Moreover, the investors would have invested their capital in other economies. Today, China is exporting capital to developing countries, as well as, United States. For instance, Chinese investment has boosted economic development of some African and Asian countries. Morrison has attributed China’s swift economic growth to two main factors namely large-scale capital investments and a swift productivity growth (Morrison 2011, p.5). These capital investments were financed by both foreign investments and domestic savings. Economists view these two factors as having moved hand in hand. Economic reforms resulted into higher efficiency in China’s economy, which in turn, enhanced national output and raised resources for additional investment within the economy (Morrison 2011, p.5). Furthermore, economists have concluded that productivity growth, or increases in efficiency have been a fundamental factor in China’s striking economic growth. This improved productivity is attributed to reallocation of resources to more productive areas particularly sectors that were previously strictly controlled by the government like services, trade and agriculture (Morrison 2011, p.5). For example, improvements in agriculture promoted production and set workers free to pursue employment in a more dynamic manufacturing sector (Morrison 2011, p.5). In addition, economic decentralization encouraged the rise of private companies. The private firms that emerged tended to follow more productive activities than the State Owned Enterprises (SOEs), and were more market-oriented and for this reason more efficient (Morrison 2011, p.5). The export sector of the Chinese economy got exposed to competition. Provincial and Local governments were permitted to estab lish and run a wide range of enterprises based on market forces and principles, without central government interference (Morrison 2011, p.5). Additionally, China has attained high rates of total factor productivity than even most of the developed economies including United States. These high rates of TFT growth are attributed to China’s ability to reach and make use of existing foreign technology and expertise. Apart from the causes of rapid Chinese economic growth reviewed above, economists have explored the role played by financial development in boosting economic development in China over the two last decades. Like other sectors, since the introduction of the 1978 economic reforms, the Chinese financial sector has experienced fundamental changes. For example, the place of mono banking was taken over by commercial banking; stock markets emerged; and modern regulatory bodies were established (Burzynska 2009, p.11; Zhang 2008, p.12). Stock markets were introduced in China in 1990. Stock markets were established in main cities including Shanghai which is a China’s oldest financial centre and Shenzhen, a fast growing city in the southern part of china for purposes of balance (Burzynska 2009, p.13). More than 75 percent of stock trading takes place in shanghai and the rest in Shenzhen. Unfortunately, even though indexes may reach greater heights and transactions prosper within China’s stock markets, some shares are not tradable (Burzynska 2009, p.14). For example, combined capitalization of Shanghai and Shenzhen stock markets as at the end of 2007 was 133% of GDP even though only 37% of GDP was tradable (Burzynska 2009, p.13). Furthermore, stock in china is more of a political affair and thus plays a minor role in financing enterprises. Politics within the stock market has led to incorrect pricing of the stock with overpricing and under pricing alternating depending on the prevailing political conditions (Burzynska 2009, p.13). Loans offered 80% of financing compared to 13% of equity in year 2007. Foreign companies are only permitted to obtain loans from banks only and can not borrow from other companies. According to Burzynska (2009), even though the debt market in china is developing it is considerably narrow, fragmented and inadequate in liquidity. It was not until 1990 that the government started to take charge of and control the bond markets seriously, which began unofficially in 1980s (Burzynska 2009, p.15). In 1997 trading of government bonds was started on the inter-bank market. The corporate bond market was reserved for various SOEs, and a considerable period remained remarkably small (Burzynska 2009, p.14). The government and policy banks issue most of the bonds. However, the volume of bonds traded has grown significantly especially since 1998 due to expansionary monetary policies (Burzynska 2009, p.14). For example, as of the end of year 2007 total bond issuance accounted for 32% of GDP (Burzynska 2009, p.14) . In a nut shell, it is the Chinese banking sector that plays the most significant role within the Chinese financial sector and is thought to have the strongest link with economic growth. Chinese financial system has numerous banking institutions. Hence, over the last decade total bank loans have accounted for over 105% of GDP (Burzynska 2009, p.15). China’s banking sector is categorized into four principal types of banks including commercial banks, state owned banks, foreign banks and rural credit cooperatives (Burzynska 2009, p.15). There are also non-banking institutions. The People’s Bank of China has served as the central bank of china since 1983. It formulates and put into practice monetary policies and controls financial markets (Burzynska 2009, p.16). However, it is not an independent entity because the government has apparent control over expansion of new financial products and levels related to interests rates on loans. The momentous question today revolves a round whether the relatively weak financial intermediaries in China have been a fundamental contributing factor to China’s rapid economic growth. Influential economists, some of which are respected authorities on Asian economic studies, have positively focused on the role of China’s financial system in its rapid economic growth. Others had used the case of China’s outstanding economic growth to prove that financial development follows economic growth given the fact that, by the time china was emerging as a dynamic economy, its financial system was poorly developed. Therefore, for such scholars current financial development is merely responding to presently required financial arrangements in a growing economy. There is, however, evidence showing that Chinese has historically maintained a high of savings even in the absence of a properly developed financial system. For example, when economic reforms were introduced in 1978 domestic savings stood at 32% of GDP (Mor rison 2011, p.5). Even though, much of these savings were produced by profits of SOEs, the 1978 economic reforms which entailed economic decentralization, resulted into a considerable rise in Chinese household savings, as well as, company savings (Morrison 2011, p.5). Consequently, Chinese gross savings as a proportion of GDP have drastically grown; it reached 53.9% in 2010; therefore, is one of the highest savings rates in the world (Morrison 2011, p.5). According to Morrison (2011), the high level of savings has allowed China to boost national investment. It is estimated that Chinese domestic saving margins surpass its domestic investment levels making China one of the largest net global lenders (Morrison 2011, p.5). Therefore, there is no dispute that financial intermediaries have contributed to Chinese rapid economic growth especially during the years following initialization of the 1978 economic reforms. These reforms apparently created a developmental space in which competitio n within the financial sector could thrive, and in the long run enabled it to contribute to China’s astounding economic growth. There is empirical evidence showing that financial development has significantly contributed to China’s high rates of total factor production (Guillaumont et al 2008, p.3). Empirical evidence has continually shown that financial development promotes China’s productivity by increasing efficiency. Financial development caused a positive and significant impact on efficiency both through expansion of credit to the private sector and through promotion of competition within the financial sector, which in turn robustly promotes China’s productivity growth (Guillaumont et al 2008, p.3; Hasan et al 2007, p.4; Calomiris 2007, p.364). However, economists, such as Maswana, have asserted that China’s rapid economic growth and financial development outcomes are irreconcilable because; its financial system is seriously weak and inefficie nt (Maswana 2008, p.1). Avid critics of the said link between China’s remarkable economic growth and its financial development cite intermediation inefficiencies such as non-performing loans and government controlled loan allocation (Maswana 2008, p.2). Conclusion China’s economic growth is certainly remarkable and hence the enormous attention it has attracted among influential economic scholars across the globe. More literature on China’s economic growth and financial development will keep on surfacing, since its rapid economic growth rate is anticipated to continue for a considerable period in the foreseeable future. This argument is anchored on the fact that there is an unresolved debate on the connection between China’s rapid economic growth and its financial development. However, it expected that as China’s technological advancement starts to catch up with that of principal developed countries, its level of productivity advantages and real GDP growth could slow considerably from its spectacular 10% economic growth rate, unless China transforms itself into a centre of new innovation and technological revolution. Furthermore, thriving of business in all sectors especially with regard to foreign investment depends largely on government’s ability to implement free-trade policies, which are in line with WTO principles.

All New People By Anne Lamott Essays - Guggenheim Fellows

All New People By Anne Lamott Essays - Guggenheim Fellows All New People By Anne Lamott I believe All New People by Ann Lamott was chosen for the Independent Thinkers Ser Sex, drugs, presidential scandals, all this and more is to be found in the magnificently written novel All New People by Anne Lamott. Probing into a timeless array of chaos and personal tragedy, Lamott manages to tie the story together with a mixture of personal experiences and documented historical references creating an almost nostalgic, dreamy tone. As Naddy Goodman, the narrator and main character of the saga is introduced, she is undergoing a series of hypnosis sessions which reveal many painful childhood memories. While none too extreme, the sheer simplicity of her emotional problems is ironic. After a lifetime of longing for emotional and physical acceptance from others, she has come full-circle to the realization that she must first accept and love herself. I especially enjoyed the way the author expresses her feelings about the breakdown of morals in society. This, to me, was best exemplified when the neighborhood fathers, including Naddys, decided the world held more fascinating things for them than they could find within the boundaries of their own, settled lives. Before this time it was almost unheard of for a father to leave his family because he was tired of it. Lamott clearly and loudly states the meaning of her book in the title, All New People. This book was written for anyone who has ever looked back on his or her life with regret. Whether a pessimist or an optimist, In a hundred years? -All new people.

Business Environment And Strategic Management Essay

Business Environment And Strategic Management - Essay Example However, Nafeeseh and Al-Mudimigh (2011) argued that although technology has increased the utility and performance of the corporations, there also exists noteworthy threats regarding the security and privacy of information shared over internet platforms. Kanet and Stà ¶ÃƒÅ¸lein (2010) observed that because of extensive competition in the international marketplace firms are trying to reduce their operational expenditure and generate a cost competitive advantage. In this context, application of technology has improved the performance of the firms by reducing the manual work capital and time required for completing the operational activities of business houses. For instance, with the help of production equipment firms can accelerate their production process and also reduce the number of man-hours required. Similarly, ICT has helped in connecting the functions of the organizations with each other with aspects such as Enterprise Resource Planning (ERP), Customer Relationship Management ( CRM), etc (Qutaishat et al. 2012). The changes in the business environment have been largely accredited to the technological changes taking place in the world. Hosman (2011) considered that technological inclusion in business firms is taking place at a rapid pace which has increased the frequency of changes being incorporated in the work structure of firms and can also hamper the performance and productivity of the business houses. There are arguments and counter-arguments regarding the role of technology in the corporate world.

Analysis Of Marketing Positioning Of Kelloggs Special K Marketing Essay

Analysis Of Marketing Positioning Of Kelloggs Special K Marketing Essay Kotler et als ideology of marketing entailing understanding consumers and their needs and designing marketing initiatives to deliver those needs (2009, p. 5) emerges in the marketing endeavors undertaken by the Kelloggs Special K (SK) cereal brand. The marketing foresight inculcated by the brand not only helped it contribute to the overall success of the Kellogg conglomerate but also helped it evolve as a strong contender in the UK cereal industry. This assignment will unravel the marketing practices followed by the SK brand by analyzing its positioning in the UK cereal market. The analyses will encompass highlighting the customer segmentation adapted by this cereal brand followed by evaluating the efficacy of its target market selection. Subsequently, it will assess the cereals positioning as compared with its competitors positioning including its usage of the marketing mix elements to sustain that positioning. Finally as an outcome of the above analysis, it will offer recommendatio ns to strengthen the brands market positioning. Assumptions Made: Barring considering the retailers as buyers for a five force analysis of the UK cereal industry, the assignment considers the end users as the consumers of the SK cereal. Whilst for a perceptual map, price  [1]  has been used to draw inferences on the product quality of the various cereal brands, Kelloggs product life cycle stage in the UK market and SKs brand share have been used to draw inferences on SKs product life cycle stage. UK Cereal Market and Kelloggs: The UK cereal market grew by 15.7% in value between 2004 and 2008 because of the perceived health benefits of and convenience in consuming cereals coupled with the declining popularity of the traditional breakfast (Worth, 2009). This growth rate indicates the attractiveness of UK cereal industry, which is also substantiated by a Porters five forces analysis of the market (represented diagrammatically in Figure 1.1). This oligopolistic market is dominated by three big brands: Kelloggs, Weetabix and Cereal Partners (Worth, 2009 and Datamonitor, 2009a) with Kelloggs leading the market (as shown in figure 1.2). Since giving the world its very first ready to eat cereal cornflakes (Emerald, 1991, p. 16), Kelloggs has become practically synonymous with breakfast cereals (Mitchell and Boustani, 1992, p. 21). With over 100 years of experience in the cereal business, it appears that Kelloggs has built its high brand value (shown in figure 1.3) on consistent pioneering innovations and incessant delivery of consumers nutritious food requirements. And keeping true to this tradition is Special K, the leading cereal brand of the Kelloggs family  [2]  . Special K and its marketing choices: Launched in the UK in 1959 (Kelloggs Special K, 2009), Special K is a nutritious low-fat, ready to eat diet cereal that owes its eminent market position to the enhanced marketing choices made by the Kellogg marketers (Kellogg Company, 2003,2004). Following section of the assignment will analyse the components of the marketing choices made by the SK brand. Market segmentation and Target Market: SK is targeted at weight conscious women, employed/homemakers, between the ages of 25-49 who desire to attain a slimmer shape either for a healthy lifestyle or for an occasion. And in pursuit of their weight goals these women will prefer to consume nutritious food substitutes including paying an above average price for the product. Alike the cereal manufacturers who use a number of variables to segment their customers (deduced from the data on consumption of cereals displayed in figure 1.4), it appears that SK also segments its customers using demographic variables such as gender, age and occupation and behavioral variables such as occasion and benefits. But unlike the other cereal manufacturers, SK utilized its customer segmentation to identify and serve a distinct market group, which proved to be attractive and profitable over catering to the entire mass market. Moreover factors that contribute to the continued success of serving this target market are: Dieting trends: Results of a consumer research carried out in 2008 revealed that women are constantly trying to lose weight, where 24.3% of the women dieted most of the time as compared to 13.9% of men (Baxter, 2009). This consumer behaviour augments SKs target market selection. Popularity of Health food: The popularity of health food is increasing as confirmed by a consumer research where 43.8% of the research pool displayed an affirmative interest in purchasing functional food. This growing trend benefits SK as women (47.3%) accounted for the majority of the preference over men (40.1%) (Taylor, 2008). UK Obesity levels: The forecasted UK obesity levels for 2010 where women (29%) are more likely to be obese then men (27%) (Gower, 2008) not only favors SKs product proposition but also provides the brand with an opportunity to expand its customer base. Grocery shopping: SK can effectively access its target market using Kelloggs existing distribution channel of grocery chains, owing to the consumer behaviour where women undertake majority of the shopping at supermarkets as compared to the men (shown in figure 1.5). Growth of UK cereal market: In addition to its current growth rate (as discussed earlier), the UK cereal market is also forecasted to prosper in the future (displayed in figure 1.6). This future growth rate, supported by an immense market potential that exists in the form of people still skipping their breakfast, enables SK to attract new customers. Whilst the above factors substantiate SKs distinctive target market selection it is also imperative to evaluate the brands positioning in this target market as compared to its competitors to gauge the success of its marketing foresight. Competitors versus Special Ks positioning: Though Porters five force analysis of the UK cereal industry reveals that competitive rivalry in this market is moderate, failure by cereal manufacturers in differentiating their products will result in increased competition. SK endures industry competition based on the category points of the parity from other health cereal brands, including the various Kellogg brands, and market competition from other slimming aids such as diets, meal replacements and appetite suppressants (represented diagrammatically in figure 1.7). Whilst the popularity of the cereals is on the rise (refer to prior discussion) the popularity of the slimming aids is on the decline due to the augmented awareness of the healthy eating habits (Baxter, 2009). Hence though the slimming aids are positioned as weight management products (Refer to figure 1.8 for the positioning of the various slimming aids in the market) also targeted at women, it can be deduced that SK has a superior market potential over these products. A perceptual mapping of SK with its industry competitors (displayed in figure 1.9) divulges that the brand is perceived as high quality premium priced product by its customers. However SKs consumer perceived value is not alone limited to its price and quality differentiation but rather is accentuated by its unique market positioning in the cereal industry. Special K is positioned as a premium shape management nutritious cereal for women The above positioning unveils that instead of imitating its competitors by using common variables such as quality, energy, taste, natural ingredients and price, SK utilizes the popular variable of body shape to differentiate its product (refer to figure 1.10). Though a number of consumer products and services use the variable of shape to differentiate their product, SK was the first cereal brand to employ this positioning making it unique in the cereal industry  [3]  . Kelloggs by using its extensive experience to develop and position the SK cereal, appears to have understood and delivered its consumer needs; where women may want to lose weight either post an occasion such pregnancy or holiday or to lead a healthy lifestyle or to improve their physical experience. The value proposition offered by SK that acts as its point of difference from the other cereal brands has also helped it minimize the risk of cannibalization from the other Kellogg cereals. Furthermore, SKs market positioning has helped convert the consumers cereal purchase decision from a low involvement to a moderate involvement activity by linking their purchase decision to the psychological and physical benefits that can be derived from the product. Infact the SK 2 week challenge, which is an important element of the brands positioning (refer to figure 1.10), facilitates potential increases in the product usage and brand loyalty as once consumers verify the benefits of the product they may want to extend their association with the brand. It can be argued that by targeting only one distinct consumer group, SK is limiting its profit potential but on the contrary the growth in its market share (depicted in figure 1.11) is a testament of its successful market positioning in highly profitable target market. However SKs current and future market share could be threatened if it is no more the only cereal adopting the shape positioning as revealed in a SWOT analysis displayed below. Hence the strength of its positioning depends on effective management of the marketing mix elements. Marketing Mix Elements: Product: SK by offering a series of value added benefits in addition to its core benefits (displayed below) appears to acknowledge the importance of support for its customers during the challenging process of weight loss. And by providing these benefits the brand has transitioned from a low fat consumer product to a perceived personal weight management partner for its customers. Furthermore it appears to understand variety seeking behaviour  [4]  of its consumers as it extended its product line to include other SK sub-brands failing which women might have used other tasty healthy cereals with the SK personal plan. The brands packaging while being environmentally and user friendly: easy to transport and store, also serves as an effective marketing tool. It provides product information and reinforces the brands positioning by illustrating its value proposition of shape on the box. Moreover by using the Kelloggs name and tag line: If it doesnt say Kellogg on the boxà ¢Ã¢â€š ¬Ã‚ ¦.it isnt Kellogg in the box on the packaging, it depicts its association with Kelloggs premium quality and high brand value thus discouraging potential brand switching  [5]  . Place: Kellogg distributes SK selectively through supermarkets, hypermarkets and convenience stores utilizing the below represented distribution network. Using popular supermarkets/hypermarkets, which are the leading medium for cereal distribution (shown in figure 1.13), is aligned with SKs target market selection (covered in a prior discussion) which is accentuated by the supermarkets ability to attract customers through their own high advertising budgets (displayed in figure 1.14). Promotion: SK utilizes promotional campaigns, advertising and interactive marketing to sustain its winning market positioning. The SK 2 week challenge, which is an integral element of the cereals offering, originated as a creative promotional campaign that helped the brand acquire its market growth (Kellogg Company 2003, 2004). Success of the 2 week challenge is largely attributable to the consumer perception that it is an easier challenge to take due to its shorter duration. Another successful campaign launched by the brand is the SK slimmer jeans challenge which astutely kicks-off at the start of the New Year when women would be keen on losing their post holiday weight and dropping a jeans size (Kelloggs 2009). SK uses its high media advertising expenditure, which is higher than any of its competitors (shown in figure 1.15) to effectively communicate its positioning to its target market. It creatively employs the informational appeal message style in its television advertisements to convey product information and benefits, aimed at sustaining and attracting new customers (as evident in its latest advertisement  [6]  ). On the downside, some women may not relate to the product as the brand stereotypes a womens body shape by using perfect size models in most of its advertisements which may also conflict with its brands positioning of slimmer shape (not perfect shape). SK also recognized the growing popularity of internet among UK consumers (Euromonitor International 2009a) and hence uses its website and facebook group, as forms of interactive marketing, to connect with its customers. SK by allowing consumers to access the brands value added services on its attractive website aims to engage its customers and encourage repeat visits. Price: As cited earlier, SK is priced higher than any of its industry competitors  [7]  (displayed in figure 1.16) which is in sync with its premium brand positioning. The brands high quality is buttressed by its high price. SKs growing brand share despite its higher pricing appears to support the consumer perception that a high value compensates for a high price. But as discussed in the SWOT analysis, SKs future product demand may decline if the consumers opt to purchase the cheaper private health cereals due to the economic recession (Worth, 2009). Moreover its future demand may also be impacted by the marketing tactics of supermarkets such as placing their cheaper cereals on the shelf next to the SK brands  [8]  . Marketing recommendations: From the above analysis, it is evident that SK is effectively managing its marketing mix elements to strengthen its market positioning. However since the brand is in the maturity stage of its product life cycle (represented diagrammatically in figure 1.17) it needs to defend its market share to avoid the onset of the decline stage. Hence the following recommendations have been offered: Firstly using its exposure of a high advertising budget, SK can enhance its promotional activities by aptly launching additional innovative promotional challenges. And increase consumer participation in these challenges by providing opportunities to win prizes such as designer wardrobes or free SK cereal vouchers. Secondly by using real  [9]  slimmer size women in its advertisements it will not only distinguish itself from the other product manufacturers who stereotype womens body shape but also may generate increased consumer confidence in the products market message. Alternatively by taking inspiration from its website, SK can incorporate the success stories of its consumers in its advertisements to reinforce the products effectiveness. Lastly owing to the growing popularity of health foods it can extend its product line to introduce other weight assistance products such as SK nutrition drinks which may complement rather than compete with the cereal. Such product introductions will also reflect the brands commitment to delivering the healthy weight management needs of its consumers. The above recommendations will not only augment SK existing strong market positioning but will also discourage possible brand switching due to the economic recession. Conclusion: This assignment acknowledges that the marketing choices made by Special K, quite like its name, prove to be special for the brand. Perceptive of its consumer needs and behaviour, Special K effectually segmented its customers and selected a profitable and sustainable target market in a flourishing cereal industry. This target market selection has immensely contributed to the special status acquired by this brand. However the true success of the brand lies in how it differentiated itself from its competitors by relying on the SHAPE positioning that also acts as the value proposition for its consumers. Though the brand astutely manages the product, place, promotion and price attributes of its marketing mix to support its positioning, the reality of its product life cycle stage cannot be escaped. Hence recommendations to improve SKs advertising, promotional activities and brand line extensions have been made to avoid the onset of the decline stage for the product. Appendix: Kellogg brand list: Kellogg offers a vast product line catering to the needs of different customer segments. Kellogg brands include All bran, Coco Pops, Cornflakes, Crunchy Nut, Frosties, Fruit n Fibre, Winders, Natures Pleasure, Optivita, Country Store, Honey Loops, Just Right, Ricicles, Start, Pop tarts, Rice Krispies, Frosted Wheats and Special K. Special K product variations: Special K Packaging: As shown in the above images, Special Ks packaging conveys that it is a low fat cereal and provides information on the personal plan and its benefits and cereal nutrition figures. The red color is synonymous with the Special K branding and labeling which not only shows it strong connection with the Kelloggs brand but also symbolizes confidence and excitement (Kelloggs Special K, 2009) that a consumer will enjoy after achieving the shape desired by them. The packaging supports easy and convenient usage through the cardboard box and plastic bag, which help in storage and preservation of the quality of the cereal. Special K in supermarkets: The observations on the shelf space occupied by Kelloggs Special K were made by visiting two large supermarkets, Tesco and Morrisons. A large section of the middle shelf space in the cereal section of the supermarkets was devoted to Special K cereals and its sub-brands. This shelf positioning helps attract customer attention and expedite the purchase process. Another observation made was that both Tesco and Morrisons placed their cheaper cereals next to Special K which may deter the purchase decision of a cash strapped consumer. Infact Tesco has also extended this marketing gimmick to its online shop as displayed in the below images.

1 1 2 3 C Motion I 7 (a) From 1 January 2009 to 10 January 2009, the watch runs slower than the actual time by 9 minutes. Therefore, when the actual time is 2:00 pm on 10 January 2009, the time shown on the watch should be 1:51 pm on 10 January 2009. Practice 1. 1 (p. 6) D (a) Possible percentage error 10 ? 6 = ? 100% 24 ? 3600 = 1. 16 ? 10 % 1 (b) = 1 000 000 days 10 ? 6 –9 It would take 1 000 000 days to be in error by 1 s.

The minimum period of time is 40 s. 6 (a) Percentage error error due to reaction time = ? 100% time measured 0. 3 = ? 100% 10 = 3% 6 7 His total displacement is 0. With the notation in the figure below. (b) From (a), the percentage error of a short time interval (e. g. 10 s) measured by a stop-watch is very large. Since the time intervals of 110-m hurdles are very short in the Olympic Games, stop-watches are not used to avoid large percentage errors. Since ZX = ZY = 1 m, ? = ? = 60 °. Therefore, XY = ZX = ZY = 1 m The magnitude of the displacement of the ball is 1 m.  © 8 (a) The distance travelled by the ball will be longer if it takes a curved path. 7 (a) Length of the path = 0. 8 ? 120 = 96 m (b) No matter which path the ball takes, its displacement remains the same.
