Cationic Antimicrobial Peptides in Humans
Cationic Antimicrobial Peptides in Humans Antimicrobial peptides Introduction Cationic antimicrobial peptides (AMPs) are gene-encoded peptides of the host defence system made up of 12-50 amino acids, with at least 2 positive charges conferred by lysine and arginine residues and about 50% hydrophobic amino acids (Hancock and Scott 2000). They are produced from gene transcription and ribosomal translation and often, further proteolytically processed (Zhoa 2003). The peptides are folded so that non-polar amino acid side-chains form a hydrophobic face and polar, positively charged residues form a hydrophilic face (Robert and Hancock 1997). Expression of antimicrobial peptides can be constitutive or inducible by infectious or inflammatory stimuli like cytokines, bacteria and lipopolysaccharides (LPS) (Cunliffe and Mahida 2004). They have diverse structures to effectively kill a wide range of microbes at prone sites e. g the skin and lungs, and in secretions such as sweat and saliva (Yeaman and Yount 2004; Santamaria 2005). Many mammalian antimicrobial peptides rouse the hostââ¬â¢s innate immune system (Jenssen et al 2006) instead of directly killing the host. Peptides which are found in living organisms from bacteria to plants, insects, fish, amphibians to mammals including humans (Kamysz 2005) are recorded in numerous existing databases e. g. AMSDb (Eukaryotic peptides) (Tossi and Sandri 2002), BAPDb (bacterial peptides), ANTIMIC (natural antimicrobial peptides) (Brahmachary et al 2004) and APPDb. Currently, 1831 peptides are hosted by the Antimicrobial peptide database with 99 antiviral, 453 antifungal, 100 anticancer and 1179 antibacterial peptides (The Antimicrobial Peptide database 2010). In humans, antimicrobial peptides are produced by granulocytes, macrophages and most epithelial and endothelial cells. They boost the immune system, have anti-neoplastic properties and help in regulating cell signalling and multiplication. Amphibian AMPs have been discovered from the skin of frogs from families ra nging from Iomedusa, Pipidae, Hyperoliidae, Ranidae, Hylidae, Discoglossidae, Agalychnis and Litoria. The structure of these peptides as unravelled by CD spectroscopy, NMR spectroscopy and molecular modeling (Suh et al 1996) have been found to be generally 10-46 amino acid residues long (Rollins-Smith et al 2005), mostly linear and simple-structured, (Conlon et al 2004) the majority being hydrophobic, cationic and possessing an amphipathic a-helix in nature. Following production, they are stored in the granular glands (poison glands) of skin dermal layer to be secreted in response to injury (Bovbjerg 1963), or as defence against pathogenic bacteria, fungi, viruses and parasites. Biologically active molecules including antimicrobial peptides are produced as large proteins harbouring a signal and an acidic propiece which get cut off to give an active peptide prior to or at secretion from the poison glands (Amiche et al 1999). Cationic peptides are also expressed in the gastric mucosa cells and in the intestinal tract (Kamysz 2005). The best-known peptides isolated from frogs are caeruleins, tachykinins, bradykinins, thyrotropin- releasing hormone (Barra and Simmaco 1995), brevinins, esculentins, magainins, ranatuerins and temporins (Conlon et al 2004). In the past, peptides were extracted using solvents like methanol or acid from the skins of amphibians after sun-drying but with concomitant dwindling of many frog species, other alternative techniques have emerged, one of which comprises stimulating the frog using mild electricity and collecting the skin secretion; 2-4 weeks after, the secretion can be re-collected after replenishment of the glands (Barra and Simmaco 1995). Large amounts of small peptides and their analogues which are resistant to protease cleavage and contain D-amino acids can be chemically synthesised while larger peptides can be expressed in a prokaryotic host from cloned cDNAs coding for a fusion protein (Piers et al 1993). An efficient means of producing therapeutic peptides in transgenic mice red blood cells has been explained by Sharma et al (1994) whereby the required peptide is collected from proteolytic cleavage from the fusion protein where the peptide is at the C-terminal end of human a-globin.

Of all the lies out there, the one that corporate executives pay is Essay
Of all the lies out there, the one that corporate executives pay is linked to the performance of their companies takes the prize. Discuss this in relation to - Essay Example For the business to be viable, it has to turn out products or services that are profitably sold to meet the needs of customers. The principals in turn may (or may not) hire managers to run the business and generate the expected profits. These hired managers (agents or executives as they are now called because they carry out or execute the plans of principals) have their own interests, the main of which is to receive adequate levels of compensation or pay to convince them to work for the principal and in such a work environment. Principals and agents therefore each have their own interests. While principals want the highest return for funds invested, agents want the highest pay they can get for their work. Their interests converge in a common desire to keep the business viable so that both continue to enjoy the rewards of their work. It is therefore to their advantage to align their respective self-interests and desires. In practice, however, this has not always been the case, as shown by events in early 20th century America when agents (managers) of railroad companies got paid well even as they mismanaged their companies, resulting in principals suffering heavy losses on their investments. Recent examples (Enron and WorldCom) show this to be still a problem. The study of thThe study of the relationship between principals (owners represented by the board of directors) and agents (managers or executives) was pioneered by Berle and Means (1932), who pointed out that the interests of the owner and the manager may diverge because of the separation of ownership and control and the absence of a system of checks and balances in the exercise of power within the organization. Unlike in a business where the owner is also the manager who works to earn the maximum profit under acceptable levels of risk, Berle and Means concluded that hired managers if these are not the same as owners tend to work with the limited aim of running the company only for their (the agent's) own profit. The experiences of modern business corporations in the last century contain numerous examples of divergence between the interests of agents and principals, with disastrous results (mainly to the principals). This led to debates by economics and finance academics as to whether an ideal ownership structure exists that would prevent the failure of a business. This issue touches the core of why businesses exist in the first place, which is to maximize profits for its owners' investments, and attempts to explain a related set of problems: why and how firms previously managed successfully by their owners eventually fail when under hired managers. Economists used to assume without question that everyone - owners, managers, employees, and lenders - act together for the good of the firm because "each one is bound by formal and informal contracts to ensure that shareholder value is maximized" (Brealey and Myers 991). After all, biting the hand that feeds them would seem unwise and against common sense for intelligent managers to do, but through the years this continued to happen as well-paid managers continue to

Hydraulic Machines Essay Example | Topics and Well Written Essays - 1000 words - 1
Hydraulic Machines - Essay Example The former types of machines are called turbines and the latter, pumps. A combination of both pump and turbine is used in fluid couplings and torque converters for the transmission of power smoothly through a fluid medium. The analysis of impact of fluid jets on vanes is typically involved in the design of an efficient turbo-machine. When a vane moves away from the jet as shown in the below figure, the mass flow arriving at the vane is considerably reduced because some of the mass leaving the nozzle results in a growing column of fluid between the jet and the nozzle. This is what happens in turbines where the vanes are part of a revolving wheel. We need only consider the simplest case of movement in a straight line in the direction of the jet. Assuming the velocity of the jet is v and the velocity of the vane is u as shown above, the velocity of the fluid arriving would be v - u. This is the relative velocity, that is, relative to the plate. The mass flow rate arriving on the plate is then calculated as The true velocity of the fluid leaving the nozzle is v1 and velocity of the vane is u. The fluid arrives on the vane with relative velocity v1-u as before, which is shown in the above figure. This is a relative velocity with respect to someone moving with the vane. In the absence of friction, the velocity of the fluid over the surface of the vane will be v1-u at all points. At the tip where the fluid leaves the vane, it will have two velocities. The fluid will be flowing at v1-u over the vane but also at velocity u in the forward direction. The true velocity v2 at the exit as shown above must be the vector sum of these two. The vector diagram is illustrated below: If only the force acting on the vane in the direction of movement is required, then the horizontal component of v2 must be determined. Because this direction is the direction in which the vane is whirling around the centre of the wheel, it is

Graduation Speech: Celebrate Your Unique Qualities :: Graduation Speech, Commencement Address
Welcome to all of you who have come to share this special evening with us. My name is John and I am a member of the graduating class of 2012. Standing here tonight is a surprise to me and to many who knew me. At one point, after making some mistakes and losing my sense of self, I dropped out of school. With my parentsââ¬â¢ urging me, I enrolled at Alternative High School. I came to this school with the hope that Iââ¬â¢d graduate on time. I knew that I would have to change, so I set goals to achieve perfection and I achieved it. As many of you may know, I am now perfect in every way, shape, and form... Yeah, right. What is true is that I had dropped out of school, was way behind my peers and enrolled at Alternative. I also worked to change my behavior. Iââ¬â¢m still working at it. During the time that I have been at this school, I have had the pleasure of meeting many seniors, as well as other students, that were talented and often possessed wisdom beyond their years. Many have survived hardships in their lives that have developed their individuality and inner strength. Some are teen parents. Some have lost parents. Some live with lifelong illnesses. Some had families that moved constantly. Some felt different from their peers. They were artists, rebels and truth-seekers. All of them were ones who chose to walk to the beat of a different drum and found a way to follow their dreams at Bunny Alternatives. Alternative High School is a school that lifts us up and celebrates our unique qualities. We have had a channel for our voices ââ¬â voices that may have been drowned out in the other crowded schools from which we came. For helping us find our strengths and our voice, we have a great number of people to thank. First, we need to appreciate the value placed on public education by the people of our country and most especially by the people of this district. Second, we need to thank the entire staff of Bunny Alternatives for encouraging us, standing by us and strengthening our skills to get us to this point in our lives. Above all, we, the Class of 2012, would like to thank our parents, mentors and friends for putting up with us during all the awkwardness of our growing up.

Ethics and Islam Essay
The interpretation of secular vs. religious ethics is always interesting, when we try to understand which of the two deserve our support. Obviously, both ethical philosophies have the right to exist among us, but the provisions of the religious ethics in Said Nursiââ¬â¢s vision are not only unique, but are sometimes surprising, and are sometimes unacceptable to those, who keep to secular ethical traditions. Said Nursi insists on ethics having religious foundations. His ethical vision is based on the assumption that religion is the source of reliable ethical knowledge. ââ¬Å"For Nursi, the ultimate source of all ethical reflection is the Qurââ¬â¢anâ⬠(Markham 69). In this situation it is possible to suggest that Qurââ¬â¢an should be simple and understandable to the common people, so that they should be able to follow its provisions. The assumption is rather debatable: on the one hand, there seems to be nothing negative or threatening in the fact that Said Nursi keeps to religious foundations of ethics. On the other hand, I may suggest that those who refuse to accept the life of the prophet Muhammad as the source of ethical knowledge, risk facing opposition from religious ethicsââ¬â¢ supporters. This ethics loses its relevance as soon as it is faced with the fact that there are possible other sources of ethics in other cultures of the world. Moreover, and I would agree with Markham, in that there is no guarantee that being obedient to Qurââ¬â¢an means seeing its wisdom; in case we do not understand the provisions to which we should keep in our ethics, it loses its relevance and meaning. The strong side of religious ethics in Said Nursiââ¬â¢s words is in accepting violence as weakness in trying to resolve various disputes. ââ¬Å"Nursi is committed to handling disagreement with peaceful means not because he shared a western skepticism about the truth of religion, but because of the truth of religionâ⬠(Markham 72). Secular ethics would easily reject these religious attitudes. While Nursi tries to justify the strength of religion, he obviously forgets that this strength is relevant only within the limited religious circles. Secularism exists and cannot be denied. For those who consider themselves being secular the strength of religion is closely connected with the power of metaphysical phenomenon. In the absence of the latter, the power of the former becomes debatable. Thus, religious foundations of ethics can be applied within the limited space of extremely religious eastern countries, which keep to Islamic religion. Especially interesting is Nursiââ¬â¢s ideas about personal ethics and social equality. His interpretation of a person in illness is rather curious, though is also natural within the eastern religious framework. ââ¬Å"O ill person who lacks patience! Be patient, indeed, offer thanks! Your illness may transform each of the minutes of your life into the equivalent of an hourââ¬â¢s worshipâ⬠(Makrham 74). The question is whether patience is equal to inactivity. Recognizing the religious value of pain and suffering is what Nursi tried to convey in his ethical teaching (Markham 75) but this also risks confusing ethics with religion, without creating any distinct border between them. Social ethics in Nursiââ¬â¢s vision tends to support equality through rejecting interest and recognizing the importance of redistribution. In these terms, Nursi seems to reject the pluralism of social status in the society. Moreover, rejection of interest is closer to rejecting secularism, than to supporting religious foundations of ethics. Conclusion The whole ethical theory created by Nursi deserves attention but seems to be founded on the grounds, which do not justify the strength of religion but better protect it from the intervention of the external knowledge. In this light religious ethics seems even more vulnerable, than Nursi tried to represent it.

Sample details Pages: 13 Words: 3917 Downloads: 7 Date added: 2017/06/26 Category Finance Essay Type Analytical essay Did you like this example? Discuss the relevant significance of the rate of interest in the determination of firms investment decisions What are the policy implications of this for a government, which wishes to promote economic growth? Alternative Theories of Business Investment Behaviour 4 Keynes on Animal Spirits 8 The concepts entailing the investment decisions made by firms, and the significance of interest rates in the preceding represents a broad as well as complex series of issues, factors, agents, inputs, policies, and other factors that impact upon this area, investments. The policy implications of governments in the preceding affects the outcomes of the circumstantial equation into where these items mesh at differing points in time, and as such represent another determining factor in how investment decisions will thus ultimately be made within this context. This examination shall examine two facets within the foregoing, 1). Donââ¬â¢t waste time! Our writers will create an original "The significance of the rate of interest in the determination of firms investment decisions" essay for you Create order The alternative theories of investment behaviour, and the competing theories that places differing emphasis on interest rate importance, along with other factors, and 2). the connection between investment and economic growth. The preceding will also include brief references to the limits that face governments in managing their economies and theories of interest rate determination to provide a balanced view of this complex subject matter. Alternative Theories of Business Investment Behaviour Interest rate, represents the profit yielded over time as a result of the utilization of financial instruments (Piana, 2002). In terms of companies, interest rates can be determined by a number of factors (Piana, 2002): The credit worthiness of the organization receiving the loan The use and aims of the plan being financed, for example, investment, working capital, consumption, with the external variables in terms of the utilization of said funds having an impact upon the interest rate computation. The number, frequency, risks and amounts of reimbursement actions in connection with the loan The locale, risks, stability and political situation connected with the end use of the investment. The corporationââ¬â¢s track record in similar investment instances as well as its position in the overall market relative to its competitors concerning sales, projected strengthens and weaknesses as well as innovations and market penetration All of the preceding are contingent upon the prevailing global interest rate within the corporationââ¬â¢s home country. The changes represented by interest rate structures are acted upon by reasons that are internal as well as external to financial markets, ass represented by the following (Stapetenand and Subrahmanyam, 1999). Differing types of interest rates influence and are linked to each other, thus the functioning of financial markets along with their relationships in the international arena represent a good portion of fluctuations in the rates. The overall economy, as well as the performance, expectations and perspectives of the corporation receiving the loan also plays an important part. The scope of globalisation thus exerts considerable influence on domestic conditions, and with financial markets being linked on an international basis as well the Central Banks of individual countries, in most instances, increased their co-operation as a result (Piana, 2002). The policy of the Central Banks represents the final determination of the countryââ¬â¢s official interest rates, and thus influences business decisions regarding the timing of potential investment decisions. Interest rate increases can be a result of one or more of the following factors (Piana, 2002): The Central Bank seeking an anti-inflationary policy to restrict the growth of the nominal money supply as well as slow rising discount interest rates. Central Bank policy of either a revaluation of the currency, and or defending the currency from devaluation. Attempt by the Treasury in covering its public deficit through the issuance of additional bonds in a market that is basically unwilling to accept more governmental debt. The ending of an inflationary stage in the country. A relaxation regarding the need to defend the exchange rate. A fall in the countryââ¬â¢s stock exchange. A fall in the overall profitability of the countryââ¬â¢s major firms. A fall in the countryââ¬â¢s private investment. A fall in credit consumption. Upward pressure on the exchange rate. Policy, and expectations greatly influence interest rates; as a result the relationship with the business cycle is therefore dependent upon decisions that are explicit, as well as subjective judgements on the part of key institutions. For example, if the use of interest rates is mainly employed to tune business cycles, then the rates will fall in recession periods slightly, and then rise on a steady basis when the economy recovers (Piana, 2002). At the end of the period of growth after the recession period, then interest rates will be increased to slow, or brake potential inflationary ramifications (Ranson, 2007). In the instance of inflation, the policy rules change. During a stagnant period, meaning whereby the Gross Domestic Product is depressed as a result of high inflation, interest rates might be high, therefore a counter cycle pattern potentially emerges (Ranson, 2007). Inflation represents a percentage increase in the price levels (Ranson, 2007). Inflation needs to be match ed by corresponding, nominal, increases in earning income; otherwise individuals within the economy become poorer. The importance of the preceding in terms of its relationship with business decisions to invest is that they do extensive research into the patterns, and policies of foreign countries, and track extensively the patterns and cycles in their home office, or main business locations, countries. Borrowing, and or building in high interest rates, and or inflationary periods erode the buying power of the funds utilized, and thus increase the investment return period for breakeven substantially. Such is made more of the case when the sums of money being utilised are quite large. Moderate inflation ranges between 5% to 25-30%, dependent upon the historical rates for the country in question, the following examples provide a clearer perspective in order to gauge the business investment significance (Ranson, 2007): Low Inflation Between 1 and 2% to 5% Moderate Inflation As is the case with most financial and economic areas, the definition of any term can have widely differing meanings dependent upon the country and region under consideration. Thus, moderate inflation is defined as existing between a range of 5% to 25%, with the higher segment of the preceding range representing ââ¬Ëhigh inflationââ¬â¢ for some countries. Extremely High Inflation This can range anywhere between 50% and 100%, and can also represent an increase in inflation representing anywhere between 30% and 50% annually. Anything hovering within this vicinity is dangerously close to ââ¬Ëhyperinflationââ¬â¢. Hyperinflation This represents the most extreme manifestation of inflation that represents annual price increases representing three-digit percentage points that grows at an accelerated rate. Inflation reduces incomes as well as consumption and savings, and can be attempted to be controlled by Central Banks via a sharp increase in real interest rates (Ranson, 2007). The preceding generally initiates a fall in investment as well as a revaluation of currency. Piana (2002) tells us that the first remedy ââ¬Å"â⬠¦ brakes domestic demand â⬠¦Ã¢â¬ while the second reduces foreign demand. Higher interest rates postpone business investment as it: Increases the cost of a companyââ¬â¢s investment, thus inducing higher risk in terms of return achievement. Represents entering an investment at the wrong period and thus inducing risk for shareholders in terms of future stock and bottom line performance, thus impacting stakeholders. Negatively impacts economic growth, as a result of reduced investment on the part of a number of businesses. Reduces the formation of new jobs. Impacts industrial output In discussing the impacts of investment in terms of interest rates, the preceding refers to both outside investment, meaning the attraction of companies into a country to establish and or expand their operations, as well as domestic companies expanding within their home markets. In the later instance, such, higher interest rates, reduce domestic production and thus competitiveness which can weaken their ability to compete with foreign firms as well as on an export level. In terms of foreign companies, higher interest rates can causes companies to seek locales with more favourable interest rates, thus representing a loss of investment, jobs, wealth creation and related factors. Henderson (2007) advises that economic growth takes place when individuals take resources and re-organise and arrange them in ways whereby they become more valuable. Money represents a key ingredient in the process as it provides the means to obtain more efficient techniques, equipment, processes, affiliation s and methods to obtain the preceding objective. Keynes on Animal Spirits Beenhakker (1996, p. 30) puts the preceding into perspective regarding publicly traded companies in that the stock price represents, among other things, the companyââ¬â¢s projected capacity to earn revenues from new plant, processes, and markets, aspects that factor in the companyââ¬â¢s recent, and planned investment(s) in these areas. Kalecki as well as Keynes (Asimakopulos, 1988, p. 147) advise us ââ¬Å"â⬠¦the key element in the determination of the level of economic activity in any short period in a capitalistic economy is the rate of investment that firms have decided to implement â⬠¦ ââ¬Å". Kaleckiââ¬â¢s (1971, p. 13) view concentrates on profits, which are directly, and positively intertwined with economic activity, and stated: ââ¬Å"Thus capitalists, as a whole, determine their own profits by the extent of their investment and personal consumption. In a way they are masters of their fate; but how they master it is determined by objective factors, so t hat fluctuations of profits appear after all to be unavoidableâ⬠John Maynard Keynes (1973, p. 121) explained the linkage between investment and economic growth as: ââ¬Å"â⬠¦the level of output and employment as a whole depends on the amount of investment. I put it in this way, not because this is the only factor on which aggregate output depends, but because it is usual in a complex system to regard as the causa causans that factor which is most prone to sudden and wide fluctuation. More comprehensively, aggregate output depends on the propensity to hoard, on the policy of the monetary authority as it affects the quantity of money, on the state of confidence concerning the prospective yield of capital assets, on the propensity to spend and on the social factors which influence the level of the money wage. But of these several factors it is those which determine the rate of investment which are most unreliable, since it is they which are influenced by our views of th e future about which we know so little depends on the propensity to hoard, on the policy of the monetary authority as it affects the quantity of money, on the state of confidence concerning the prospective yield of capital assets, on the propensity to spend and on the social factors which influence the level of the money wage. But of these several factors it is those which determine the rate of investment which are most unreliable, since it is they which are influenced by our views of the future about which we know so little â⬠¦Ã¢â¬ The relevance of the foregoing is that unless a firm has sufficient savings to finance its investment(s), it seeks outside financing through banks, and thus is subject to interest rates, as explained. In all cases, the binding agent, in terms of interest, economic policy and investment decisions is represented by the human factor. In equating this facet, Keynes refers to ââ¬Ëanimal spiritsââ¬â¢, whereby decisions impacting and affectin g the future ââ¬Å"â⬠¦ cannot depend on strict mathematical expectation â⬠¦Ã¢â¬ (Melberg, 2007). Keynes asserts that the foregoing is true ââ¬Å"â⬠¦ since the basis for making such calculation does not exist â⬠as they are based upon projective inputs, and speculation as to how future events might proceed (Melberg, 2007). His, Keynes, ââ¬Å"â⬠¦ writings on uncertainty are widely acknowledged by, and indeed have clearly influenced the thinking of many economists â⬠¦Ã¢â¬ (Lawson, 1993). Harris and Knopf (1947, p. 50) explain that the cornerstone of the Keynesian system is based upon the rate of interest. They advise that ââ¬Å"â⬠¦ Keynes was very optimistic concerning the effectiveness of monetary expansion operating through the rate of interest in pulling a country out of the quagmire of deflation â⬠¦Ã¢â¬ (Harris and Knopf, 1947, p. 50). In Keynesââ¬â¢ ââ¬Å"â⬠¦General Theory, he stressed the relation of the rate of interest, and marginal efficiency of capital as a determinant of the amount of investment and hence of employmentâ⬠(Harris and Knopf, 1947, p. 50). In explaining ââ¬Ëanimal spiritsââ¬â¢, Harris and Knopf (1947, p. 50-51) tell us that in making calculations, estimates, and projections concerning the probability of future events ââ¬Å"An estimate of what an investment will earn five, ten, or twenty years hence is based largely on guesswork, on animal spirits, on adapting estimates to the average estimate, which in turn is based on uninformed guessesâ⬠, thus uncertainty represents a deterrent to investment. ââ¬Å" Arestis et al (2002, p. 21) explain ââ¬Å"In the Keynesian case there are different types of agents consumers, workers, producers, renters and entrepreneurs. There is an overlap between these categories. Thus producers and entrepreneurs overlap, as do consumers and workersâ⬠Keynes statement on ââ¬Ëanimal spiritsââ¬â¢ represents how decision makers foc us on the differing agents acting in the economic stage, and the action between these agents that he stated is based upon projections that in reality individuals do not have a basis for making decisions upon (Arestis et al, 2002, p. 21). The expectation of entrepreneurs concerning profits that has the probability of a high degree of variance is also subject to the individual interpretations based upon internal equation systems, animal spirits, that are uncertain, and or undefined as the calculations, and projections that are being utilised to make the decisions (Arestis et al, 2002, p. 21). Lawson (1993) does advise however ââ¬Å" â⬠¦Although the situation as a whole may be characterized by a degree of instability, the fact that agents fall back on convention does, within the wider existing institutional framework, also allow for a significant degree of structural stability to prevail â⬠¦Ã¢â¬ . Keller (1983, pp. 1087-1095) tells us that post Keynesians, and institutionali sts share the same concepts regarding time, money as well as society. Tymoigne (2003) aids us in summarising the foregoing Keynesian concept: ââ¬Å" â⬠¦ time is historical, it implies that decisions are irreversible and that uncertainty matters and shapes the behaviour of economic actors. This appears notably through the use of money, which permits the transfer of purchasing power from the future to the present (satisfaction of animal spirits) and the transfer of expected purchasing power in a safe form, from the present to the future (liquidity preference)â⬠Connection Between Investment and Economic Growth The case for the connection between investment, and economic growth is amply demonstrated by China. The country introduced its first round of economic reforms in 1979, which represented the Central governmentââ¬â¢s plans to put into place incentives for internal savings, and investment to build the economy (Morrison, 2006). During the period 1960 through 2005, the average annual growth rate of the Chinese economy grew from 5.3% to 10.1%, which economists attribute that much of the foregoing was and is a result of two principle factors (Morrison, 2006), large scale investments, as financed by domestic savings as well as foreign investment, and a rapid growth in productivity In addition, it is also acknowledged that the economic reforms led the country to increased economic efficiency (Morrison, 2006). The preceding is hailed as boosting production output as well as increasing the resources to result in additional investment. The following illustrates the growth in Chinaââ¬â ¢s Gross Domestic Product for that period: Table 1 ââ¬â Chinaââ¬â¢s Average Annual Gross Domestic Product Growth Rates, 1960 ââ¬â 2005 (Morrison, 2006) Time Period Average Annual % Growth 1960 ââ¬â 1978 (pre-reform) 5.3 1979 ââ¬â 2005 (post reform) 9.7 1990 3.8 1991 9.3 1992 14.2 1993 14.0 1994 13.1 1995 10.9 1996 10.0 1997 9.3 1998 7.8 1999 7.6 2000 8.4 2001 8.3 2002 9.1 2003 10.0 2004 10.1 2005 9.8 The case for investment, and economic growth is further found in Chinaââ¬â¢s high savings rate. In 1979 the countryââ¬â¢s domestic savings as represented by a percentage of GDP was 32%, which was primarily a result of state-owned enterprises (Morrison, 2006). The preceding was used by the government to increase domestic investment, and through economic reforms household savings underwent substantial growth, and thus now account for 50% of all domestic savings (Morrison, 2006). The reforms have aided the yearly increase in savings to the point where savings, as a percentage of Gross Domestic Product, has risen to 49% in 2004, making the foregoing the highest in the world (Morrison, 2006). The example of China has been used to illustrate the ties between interest rates, investment, and economic growth. It is by no means an isolated case, as evidenced by the growth of the Asian Tigers, and other examples. In equating the success of China, as well as the Asian Tigers and other high growth rates, it is important to establish comparative examples. Developed economies, the steady growth rate model indicates total savings, as represented by the formula (Kaplan, 1999): Total Savings = Private Savings + Public Savings + Net Foreign Savings To explain why less developed countries have productive capacity growth rates representing double, triple and greater on an annual basis, as compared to developed economies that range between 2% to 5% per year, one needs to look at the Solow Model for the difference in potential output growth (Kaplan, 1999). Mankiw (2007, p. 186) advises that the purpose of macroeconomic analysis represents the explanation of why the income of nations grows, and why the economies of some countries grow faster than other countries. In explaining the preceding, Mankiw (2007, p. 186) discusses the inputs of: production, capital, labour, the countryââ¬â¢s economic output, and thus its total income. He explains that the differences in terms of income are result of differences in labour, capital as well as technology (Mankiw, 2007, p. 186). The Solow growth model illustrates how savings, along with population growth as well as technological progress have a direct effect upon a countryââ¬â¢s economic output, and thus its growth (Mankiw, 2007, pp. 186-187). Savings represent the key determinant in investment as plentiful money aids in lowering interest rates in conjunction with the Central Bank, and governmental policy, taking into account other factors. Solowââ¬â¢s model explains that less developed countries in almost all instances have lower living standards, along with smaller economies, less capital as well as lower capital ratios than developed nations (Kaplan, 1999). As a result, lesser-developed nations do not need to devote a large portion of their savings, and investments to replacing depreciated plant, equipment, and other assets therefore leaving more for new asset development. In addition, the lowered costs of doing business, purchase, and or the leasing of land for plant, and or offices as well as the lowered costs of labour, related business expenditures, and in the case of China and or India, their huge domestic markets, makes investment a growth proposition (Kaplan, 1999). The preceding eventually balances out as LDCââ¬â¢s achieve a comparable internal market, and industrial development, falling into a ââ¬Ësteady state rate of growthââ¬â¢ that identifies developed economies. Mankiw et al (1992, pp. 407-437 in an empirical note advises that the reservations in the Solow model that he raised concerning if balanced growth represents the norm, states the neoclassical growth model is widely accepted as it generates explanations for economies nearing the steady state growth rate (Blankenau and Cassou, 2004). The foregoing, ââ¬Ësteady state economyââ¬â¢ is defined as one having a relatively stable as well as mildly fluctuating population and per capita consumption (Czech and Caly, 2004). Kumar (2007) sums up the preceding in stating that investment represents the manner in which countries as well as companies utilise financial assets to create wealth through investment in plant, equipment, technologies and market locations. The significance of interest rates in the determination of the investment decisions of business firms represents a cost analysis factor based upon the utilisation of a financial asset to yield an agreed upon, and a rate of overall return that compensates for the use of money in an environment that has acceptable risk. Such is subject to variable that are outside of the control of the company in that is depends upon the state of international economics, monetary policies, consumption patterns, future market stability, and savings. This entire complex series of interactions is dependent upon the actions of individuals, most of whom are working towards their own firm and or institutional self interests to maximise their returns. Interest rates represent the binding foundation of the overall calculation starting point in that future projections as to the impact of the anticipated use of funds for a specific purpose is dependent upon future factors and forecasts that may or may not accurately predict those events. The preceding is referred to as ââ¬Ëanimal spiritsââ¬â¢ by Keynes, representing that individualized nature of the internal decision processes, and the uncertainty of events, which are used in arriving at the determinations. Governmental policies are reactionary in terms of addressing shifts in economic trends, both internal and externally that impact upon their countries. In addition, immediate, short-term, intermediate and long term policies enacted by governments on an individual and collective basis influence these events, thus forcing further in-phase adjustments to achieve outcomes. These are all predicative facets responding to the foregoing that seek to moderate present and future events into more favourable outcomes within individual economies. Central Bank actions in consort with the preceding are inputs contributing to the equation to attempt to create an internal economic environment that is conducive to growth, and market stability to present instances whereby the longer term prospects point to a business condition companies seek to basis investment decision in and upon. The foundation, as stated, rests in interest rates as well as future economic growth prospects that are representative of market conditions, which will yield anticipated returns. As Keynes aptly stated, the entire equation of uncertainty underpins the process. Firms do have a degree of control in that their past fiscal performance, if positive, aids in their being offered interest on more favorable terms, however, such is still subject to the vicissitudes of the overall international and national environment that consi sts of decisions made individually and in consort regarding economic variables.

The Social Justice Issue Of Poverty - 963 Words
RESEARCH THE SOCIAL JUSTICE ISSUE What is it: Many describe poverty as an economic deprivation, or lack of income. However, this alone does not incorporate the different social, cultural and political aspects of this unfortunate reality. Poverty is not only a deprivation of economic or material resources but a violation of human dignity. The general scarcity, lack, or the state of one without a specific amount of material possessions or money. It is a versatile concept that may be defined as either absolute or relative.
