CULTURAL METAPHORS and THE WEEKLY CULTURAL FOCUS SECTIONS (japan) Research Proposal
CULTURAL METAPHORS and THE WEEKLY CULTURAL FOCUS SECTIONS (japan) - Research Proposal Example of the culture is important not only to facilitate proper business transactions but also since total comprehension of a different culture gives room for appreciation of other cultures thereby promoting peaceful coexistence. Therefore, an understanding of the Japanese culture boosts my future career endeavors as an organizationââ¬â¢s representative in international forums. Nonetheless, cultural studies require extensive research from different resources ranging from the internet to books among others. The Japanese culture has been covered by relatively many books that are dependable. As such, most of my research will be based on books through the guidance of the librarian on the best reference books. Additionally, I plan to use the internet since it proven to be a great resource especially for information on current issues such as through newspapers and journals. After picking the best at least five references, I will use them to come up with an annotated bibliography which is essential in drawing summaries for the final paper. With this I hope to not only have created an excellent final paper but also to have gained sufficient knowledge regarding the Japanese

Thesis for POS Systems Essay Example for Free
Thesis for POS Systems Essay ABSTRACT Several threats affect the survival of small, independent retail companies. Adoption and use of Point-of-Sale (POS) systems may offer important benefits to counter these threats. POS systems are not widely used by these retailers, however. This research investigates the determinants of the adoption of POS systems using a conceptual model based on existing adoption theories. Based on this, a survey has been held among 37 Dutch small, independent retailers, to answer the question what the most important determinants for POS system adoption are. This study furthers theory on IT adoption, specifically for small organizations. The practical relevance is that its findings may help in improving POS system adoption. . INTRODUCTION The Dutch retail sector consists for 94% of small retail organizations (âⰠ¤10 employees), altogether employing around 250,000 persons. The retail sector is noticeably present in the trade-driven Dutch economy and acts as an intermediary between industry and consumer. The sector is an important and relevant subject of study from an economical, social and cultural perspective. In this paper we focus on in-store retailing. The environment of this type of retail trade is under pressure. Several interacting threats, like globalization, demanding consumers, increasing administrative burden and an economic recession force the retailers into action. Information and communication technology (ICT) is a double-edged sword in this context (cf. Turban, King, Viehland and Lee, 2004). On the one hand, it can be a threat to smaller retailers for its disintermediation effects and competition through e-tailing (cf. Chircu and Kauffman, 1999), and by its supply chain management effectuation of the larger(franchise) organizations (cf. David, 2008). On the other hand, ICT likewise provides opportunities to smaller retailers, like opening up new sales channels, reducing administrative tasks and/or enabling strategic management of their enterprise (Turban et al., 2004). A specific type of retail ICT that can be employed to achieve effective store management is a ââ¬ËPoint-of-Saleââ¬â¢ (POS) system. POS systems are defined in many different ways. On Wikipedia, a retail POS system is defined as ââ¬Å"a computer, monitor, cash drawer, receipt printer, customer display and a barcode scannerâ⬠. Webopedia.com defines a POS system as ââ¬Å"the capturing of data and customer payment information at a physical location when goods or services are bought and soldâ⬠. YourDictionary.com defines it as: ââ¬Å"A comprehensive computerized checkout system that includes a bar-code scanner, receipt printer, cash drawer, credit and debit card scanner, monitor, and inventory management software. A point-of-sale system tracks sales and identifies inventory levels in real timeâ⬠. There are many different types and brands of POS systems available. eBay.com and BuyerZone.com provide a web-based ââ¬ËPoint of Sale System Buying Guideââ¬â¢, containing over 4,000 different POS equipments for retailers, and 91 different types of POS software. The POS system market in The Netherlands contains no less than 150 vendors, each offering their own ââ¬Ëuniqueââ¬â¢ software package. POS systems enable retailers to consult more detailed management information compared to traditional cash registers and Electronic Cash Registers (ECRs). As this management information is based on sales figures, retailers can improve their business by maintaining a better product strategy and pursuing a more efficient replenishment process matching customer demand, alleviating what is often referred to as the ââ¬Ëbullwhip effectââ¬â¢ (Lee, Padmanabhan and Whang, 1997). This enables inventory optimization, minimizing storage space and ââ¬Ësold-outââ¬â¢ situations. Moreover, cash slips can be stored electronically and the results can be brought up in the POS system immediately, both reducing time spent on administrative tasks. This is specifically relevant for The Netherlands, where the administrative burden for SMEs has increased through regulations LITERATURE REVIEW: ADOPTION MODELS In this section we review eight different studies on the adoption of information systems, which were found through literature study. The meta literature search focused on theories and models concerning IS/IT adoption, more specifically of small businesses, retail and/or POS systems. Below, as a result, we first describe two generic adoption models with regard to IS/IT adoption. Next, we discuss six models that address adoption within the retail or small business domain. Generic models The first generic adoption model we refer to here is that of Rogers (2003). His Diffusion of Innovations (DOI) theory describes the adoption of innovations over time. He ascribes the dynamics of adoption behaviour in terms of different groups of people, like innovators and laggards. His theory also indicates how an individual or organisation (i.e. any decision-making unit) decides to adopt (or not) an innovation. This adoption process consists of five different stages: knowledge acquisition, persuasion, adoption, implementation and confirmation. Rogers specifies three groups of determinants that influence this process: characteristics of the decision-making unit, characteristics of the innovation and information channels. Based on DOI theory, factors concerning the decision-making unit that positively influence adoption are e.g. high social status, low age and financial flexibility. According to DOI, important characteristics of an innovation include: relative advantage, compatibility, complexity, trialability (the degree to which it can be experimented with), and observability (the visibility of its results). Information channels (personal and mass communication channels) are required to spread knowledge of an innovation. The second generic adoption model is based on Venkatesh, Morris, Davis and Davis (2003), who reviewed technology acceptance models, among which the Technology Acceptance Model (Davis, 1986) and the Theory of Planned Behaviour (Ajzen, 1985). They used elements of each model for a new unified model, called the Unified Theory of Acceptance and Use of Technology (UTAUT) model. Contrary to Rogersââ¬â¢ model, UTAUT concentrates on the adoption behaviour of individuals. In this model, four constructs are defined as determinants of a userââ¬â¢s acceptance and behaviour. Performance expectancy relates to the degree to which the technology is expected to improve job performance. Effort expectancy concerns the ease of use associated with the technology. Social influence is defined as ââ¬Å"[t]he degree to which an individual perceives that important others believe he or she should use the new systemâ⬠(Venkatesh et al., 2003). Finally, the construct facilitating conditions deals with the degree to which a support infrastructure for the technology is believed to exist. In addition, these four constructs are modelled to be influenced by four so-called moderators, i.e. gender, age, experience and voluntariness. Retail and SME-specific models We will discuss six main studies and their adoption models below. First, the study by Julien and Raymond (1994) can be mentioned. Their technology adoption model for the retail sector proposes eight organizational aspects as determinants of technology adoption: centralization, complexity, size, status (i.e. independent/affiliated), sector, and assertiveness, rationality, and interaction of the organizational strategy. These determinants were identified in earlier research on technology adoption in small organizations. Technology adoption in this case concerned the use of hardware (business computing, POS systems and telecomputing) and software. In the study 79 firms in food, hardware and clothing were assessed through questionnaires and semi-structured interviews. Clothing firms and large firms were less apt to use POS systems, while firms that had a longer organizational planning horizon used POS systems more often. Secondly, Chau (1995) researched which factors are important for small businesses in software selection. His research focused on packaged software, as small organizations usually do not buy custom developed software, due to their limited resources. Chau argues that owners/managers of small organizations are less focused on budgeting techniques like ââ¬Ënet present valueââ¬â¢ or ââ¬Ëinternal rate of returnââ¬â¢ to make decisions on software investments. Instead, they focus more on criteria aimed at the functionalities and popularity of the software. Also, opinions of vendors, employees, consultants or acquaintances are believed to influence decision making. Based on empirical research among 122 small businesses, he found that the importance of selection criteria varied between owners and managers. In general, owners seem to focus more on technical aspects, while managers focus more on non-technical aspects. Third, Thong and Yap (1995) developed a model based on the notion that the adoption process of small businesses differs from that of large firms. CEOs play a major role in small firms as they are the primary decisions makers. In their research, the authors developed a causal model, which assumes that the following factors are positively correlated with the likeliness of IT adoption for small firms: business size, competitiveness of the business environment, information intensity, innovativeness, and attitude towards adoption of IT and IT knowledge. SYNTHESIS: CONCEPTUAL MODEL AND HYPOTHESES In the previous section, a total of eight models for adoption have been discussed. Most models view the (retail) organization and/or its owner as the decision-making unit. In small organizations, the owner-manager/CEO almost by definition determines IT investments and the IT strategy. Thong and Yap (1995), Ekanem (2005) and Chau (1995) all point out this phenomenon. Therefore, we consider personal variables of the owner (like age and gender) as key determinants of POS adoption by retailers. In addition, organizational characteristics (like size and competition) can be considered as additional, contextual determinants of the IT adoption decision.

Experimental Investigations of Catalytic Effect of Cu2+
Experimental Investigations of Catalytic Effect of Cu2+ Experimental Investigations of Catalytic Effect of Cu2+ During Anodic Disolution of Iron in NaCl Electrolyte R.K Upadhyay1, Arbind Kumar2 and P.K Srivastava3 Abstract: Taguchiââ¬â¢s orthogonal array L9 has been effectively used to study the effect of process parameters such as voltage, feed rate and electrolyte concentration on material removal rate in context of two different types of electrolyte namely aqueous NaCl solution and electrolyte solution containing Cu2+ ions. The results indicated that Cu2+ has a catalytic effect on the anodic dissolution of iron, which restrict the oxidation of Fe2+ to Fe3+ and increases the dissolution rate during machining. The experimental results were analyzed using analysis of variance (ANOVA) method to investigate the significance and percentage contribution of individual process parameters on performance characteristics. Key Words: Electrochemical Machining, Aqueous NaCl, Cu2+, Parameters, Oxidation, Material Removal rate. Introduction: Electrochemical machining (ECM) has got an industrial importance due to its capability of controlled atomic level metal removal1. It is an anodic dissolutionà process based on electrolysis, where the application of a more traditional process is not convenient. ECM has been successfully employed in aerospace, automobile industries and now gaining much importance in the electronics and other high-tech industries for the fabrication of micro components2-3. Mask less and through mask electrochemical micromachining techniques have been successively used thin films and foils of materials those are difficult to machine by other methods4-5. Electrochemical machining is low voltage (5-25 volt) machining process which offers high metal removal rate and also capable to machine hard conductive materials into complicated profiles without any thermal damages thus suitable for mass production work with low labor requirements6-7. The dissolution rate is highly reliant on the selection of electroly tes and its current carrying capacity. On increasing the concentration of electrolyte solution dissolution rate also increases but excess concentration allows the crystal formation, which may damage the accessories of ECM and reduce the volume of electrolyte in flow pipes. The conductivity of electrolyte depends not only on the concentration but also on ionic interaction. Thus, the current carrying process done by the base electrolyte is small, but H+ and OH ions produced in electrolysis of water play important role8-9. The achievement of higher dissolution rate in ECM is a strong research base which is possible by change in composition of electrolyte solution to promote catalytic effect during dissolution10. During electrochemical machining of iron at low current density it has been observed that Fe+ cation formed very easily but it is highly unstable and immediately oxidizes into Fe2+ state. Increase in current density leads to simultaneous production of Fe2+ and Fe3+, at higher current density apparent valence of iron increases above three11. Therefore, to stabilized Fe2+ in the aqueous solution is a challenge during dissolution. EXPERIMENTAL SET-UP AND PRINCIPLE OF ECM: Fig 1 Experimental set-up ECM is an anodic dissolution process works on the principle of Faradays law. While machining of iron in presence of aqueous NaCl electrolyte solution the following chemical reactions are observed12. Reactions at Cathode: Na+ + e à ¯Ãâà ³ Na Na + H2O à ¯Ãâà ³ NaOH + H+ 2H+ + 2e à ¯Ãâà ³ H2 It shows that only hydrogen gas will evolve at cathode. When pure iron is being machined electrochemically the following reactions would occur13-14. Fe à ¯Ãâà ³ Fe2++ 2e Fe2+ + 2Cl à ¯Ãâà ³ FeCl2 Fe2+ + 2(OH) à ¯Ãâà ³ Fe(OH)2 FeCl2 + 2(OH) à ¯Ãâà ³ Fe(OH)2 + 2Cl 2Cl Cl2 + 2e 2FeCl2 + Cl2 à ¯Ãâà ³ 2FeCl3 H+ + Cl à ¯Ãâà ³ HCl 2Fe(OH)2 + H2O +O2 à ¯Ãâà ³ 2Fe(OH)3 Fe(OH)3 + 3HCl à ¯Ãâà ³ FeCl3+ 3H2O FeCl3+ 3NaOH à ¯Ãâà ³ Fe(OH)3 + 3NaCl It shows that during electrochemical machining of iron in NaCl electrolyte, iron is removed as Fe(OH)2 and precipitated as sludge while sodium chloride is recovered back. Due to further reaction, formation of Fe(OH)3 is also possible Which, confirms the existence of iron in +2 and +3 states during dissolution. Determination of Fe2+ and Fe3+ ions in electrolyte solution: The electrolyte solution containing Fe+2 and Fe+3 ions was collected. Fe+2 ions were determined directly by titrating a known volume of iron electrolyte solution with K2Cr2 O7 in acidic medium (HCl). Cr2O7 2- + 6Fe+2 + 14H+ = 2Cr+3 + 6Fe +3 + 7H2O Internal indicator N- phenyl anthranilic acid was used to mark the end point. Fe+3 ions were determined after all the Fe+3 ions are reduced into Fe+2 ions with SnCl2 in presence HCl in hot. Sn+2 + 2Fe +3 = Sn+4 + 2Fe+2 The solution was then cooled and excess SnCl2 was removed by adding HgCl2 solution. 2Hg+2 + Sn+2 +Cl = Sn+4 +Hg2Cl2 (white ppt) Titration of known volume of standard solution was done using standard solution of K2Cr2O7 in acidic medium. From the volume of K2Cr2O7 used, the total amount of Fe+2 and Fe+3 ions was determined. The amount of Fe+3 ion was determined by subtracting amount of Fe+2 which is determined earlier. Material removal rate during electrochemical machining is greatly influenced by dissolution valence. As the dissolution valence decreases MRR increases. In this paper an approach is made to enhance the electrochemical dissolution of iron through control of valency (transition) therefore, in this direction, use of electrolyte solution containing Cu2+ is suggested. The dissolution limit of iron by Cu2+ ions can be is justified by considering the standard electron potential Eà ° for Cu2+, Fe/Fe2+and Fe/Fe3+ described as follows15. Cu2+ + 2e- Cu Eà ° = +0.34V Fe2+ + 2e- Fe Eà ° = -0.44V Fe3+ + e- Fe2+ Eà ° = +0.77V As Eà ° for Cu2+ Cu is more positive than Fe2+ Fe, Cu2 +will oxidize Fe to Fe2+. However, as Eà ° for Cu2+ Cu is less positive than Fe3+ Fe2+, Cu2+ will not oxidize Fe2+ to Fe3+. Making electrolyte solution: 250 gramsof NaCl was mixed with400 gramsof CuSO4 in10 litersof water. The mixture is stirred well for 2 minutes then heated until it loses its green color. The crystals of sodium sulphate (Na2SO4) and copper chloride (CuCl2) were removed by filtering the solution and thi the solution thus obtained was saturated solution of Na2SO4 containing Cu2+ ions which participates in anodic dissolution process. MACHINING CONDITIONS: Following machining parameters are selected on the basis of performance characteristics, Table1: Machining conditions for analysis SELECTION OF MACHINING PROCESS PARAMETERS Table 2 shows machining parameters and selected levels for experimental procedure Table 2: Process parameter and their levels Measurement of MRR The initial weight of the work piece was taken for calculation of MRR. Keeping the flow rate constant at 15 lit/min and the rest of the parameters are set according to table 1 for each run. Work piece was kept horizontal, and cylindrical electrode was used for machining. Gap between tool and workpiece was maintained carefully to avoid the choking. The electrode was fed continuously towards the work piece during machining and time was recorded. After machining, the cavity was formed on the work-piece. The final weight of the work-piece was taken and material removal rate was calculated as per the following formula: MRR= â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦. (1) EXPERIMENTAL PROCEDURE: The design resulted in total of eighteen experiments, which are performed at 10V-18V supply voltage, 10-30 g/lit electrolyte concentration and 0.0001-0.0005 cm/sec feed rate as the values for the control variables. The responses measured are Material removal rate (MRR) Scheme of the experiments is as shown in Table 3. Table 3: Taguchi L9 OA for MRR RESULTS AND DISCUSSION Analysis of Variance (ANOVA) when machinating in presence of NaCl electrolyte solution: Percentage contribution of each parameter on material removal rate during electrochemical machining of iron in aqueous NaCl electrolyte solution is shown in table 4 and represented graphically in figure 2. Table 4: ANOVA for MRR [NaCl as electrolyte] Fig 2.

The graphs shown in figure 3 are plotted from the regression equation (2). Fig 3. Main Effects Plot for SN ratios (NaCl electrolyte solution) Figure shows the main effect plot of the MRR depicting the effect of various machining parameters on MRR. As seen from the plot obtained, the MRR increased with increase in both voltage and feed rate. This is due to the fact that with increase in voltage the current increases in the inter electrode gap thus increasing the MRR. Feed rate is another important parameter. Increase in feed rate results in decrease of the conducting path between the workpiece and the tool hence resulting in high current density thus enhancing the rapid anodic dissolution. An overall increase in the MRR was also observed with increase in the concentration as the larger number of ions associated with the machining process which increases the machining current and thus results in higher MRR. Effects of selected process variables (i.e. Voltage, Feed rate and Concentration) on material removal rate (MRR) at different sets of conditions while machining in presence of aqueous NaCl solution are shown in figure 4(a), 4(b) and 4(c). Fig. 4(a) Effects of Voltage on material Fig. 4(b) Effects of Feed rate on material removal for different Concentration, removal for different Voltage, Feed rate= 0.0001 cm/sec. Concentration = 20 g/lit. Fig.4(c) Effects of Concentration on material removal for different Feed rates, Voltage= 14 V NaCl electrolyte tend to promote the oxidation of Fe2+ to Fe3+ during the dissolution process the maximum MRR obtained during machining of iron in aqueous NaCl solution recorded was 0.0653 cm3/sec. Although the higher concentration of NaCl is favorable for better MRR but excess concentration allows the crystal formation which reduces the volume of electrolyte in flow pipes and also affects the dissolution rate. Analysis of variance when machining in presence of electrolyte solution containing Cu2+ ions Percentage contribution of each parameter on material removal rate during electrochemical machining of iron in electrolyte solution containing Cu2+ ions is shown in table 5 and represented graphically in figure 5. Table 5 ANOVA for MRR [electrolyte solution containing Cu2+ ions] Fig 5.

(3) The equation (3) shows that voltage is dominant factor affecting MRR. The graphs shown in figure 6 are plotted from the regression equation (3). Fig 6. Main Effects Plot for SN ratios (electrolyte solution containing Cu2+ ions) The oxidation of Fe2+ in to Fe3+ is restricted due to the presence of Cu2+ in electrolyte solution which promotes the higher dissolution rate during machining. The influence of selected process variables i.e. Voltage, Feed rate and Concentration on material removal rate at different sets of conditions in presence of electrolyte solution containing Cu2+ ions are shown in figure 7(a), 7(b) and 7(c) respectively. Fig. 7(a) Effects of Voltage on material Fig. 7(b) Effects of Feed rate on material removal for different Concentration, removal for different Voltage, Feed rate= 0.0001 cm/sec. Concentration = 20 g/lit. Fig. 7(c) Effects of Concentration on material removal for different Feed rates, Voltage= 14 V. The maximum MRR obtained during machining of iron in presence of Cu2 electrolyte solution containing Cu2+ ions was 0.0774 cm3/sec, which is 18.5% more when compared with aqueous NaCl electrolyte. CONCLUSION The electrochemical characteristics of iron in aqueous NaCl solution and electrolyte solution containing Cu2+ ions has been analyzed experimentally to investigate the influence of process parameters on MRR. The Process parameters such as voltage, feed rate, Electrolyte concentration, were successfully controlled. The different combinations of these parameters were used for the experimentation in order to determine their influence on MRR. The experiment was performed by varying all parameters in combination as per L9 orthogonal array. The experimental observations support the conclusion that the presence of Cu2+ ions in electrolyte solution restrict the further oxidation of Fe2+ to Fe3+ and enhance the low valence dissolution of iron during machining. Design of experiments and analysis of variance helped in identifying the significant parameters affecting MRR. The best combination of the parameters are Voltage= 18 V, Feed Rate=0.0005 cm/sec and electrolyte Concentration = 20 g/lit whe n using a solution containing Cu2+ ions as electrolyte. The maximum MRR obtained was 18.5 % higher when compared with aqueous NaCl electrolyte for the same set of working conditions.

Saving The Animals? :: essays research papers fc
Saving the Animals? In Buffalo New York on October 23rd of last year, Dr. Barnett Slepian was murdered. He wasnââ¬â¢t killed because of his financial status or because of a dispute he had with a patient. Someone who never really knew Dr. Slepian, someone who never met his family, a person who didnââ¬â¢t agree with Dr. Slepianââ¬â¢s job, took his life. This is a great example to show how a disagreement in ideology can lead to actions that no one has the authority to take. An animal liberator bombing a meat processing plant is like the pro-life activist killing the doctor who performs abortions. Both of the actions donââ¬â¢t achieve the results that are intended, they both claim that they help save the lives of the innocent, and they are both hypocritical. The results that are wanted can not be achieved through causing pain and suffering to the opposing party. When a sniper took the life of Dr. Slepian he was trying to move the cause of pro-life forward. The end result was not what he had wanted; the medical community was outraged and the people who believed in the right to choose strengthened their resolve. This quote by Dr. Henry Morgentaler, the countryââ¬â¢s best-known pro-abortion crusader, illustrates this point very accurately. "This is a sign of the moral bankruptcy of the so-called pro-life movement. It bespeaks their frustration and rage at the fact that they have not been able to convince the public of the rightness of their cause," (Cnn 2) The frustration that Dr. Morgentaler mentions is even further enhanced when the pro-lifers see that their cause is regressing from public empathy. The example of the murder of Dr. Slepian is a good analogy to what the bombing of the meat processing plant would cause. The people in the factory would be massacred and the people who donââ¬â¢t support the cause of animal liberation would be outraged. The intended result of lower consumption of animal meat would not be achieved because the pub lic would not see the righteousness of the cause; and where there is demand for meat there will be suppliers to meet the demand, this is a basic law of economics. Even if the bomber would bomb every single meat-processing plant in the country, intrepid businessmen would find ways to meet the demand in the country. Murder has always been an unacceptable action in modern society.

The Effects of Media Propaganda
AbstractThe media serve the agenda of six corporations that owns them. Just about any source of information that you see, hear or read is controlled by the agenda of the six corporations. They control the country with media propaganda agenda using the illusion of choice. The media has influenced us, economically, sociologically, and psychologically.The media function with the intent to shape our thinking into believing what they wanted us to believe. Many of the news coverage in the media is due to the fact that it align with the media agenda. This would paper allowed us to see different areas we have been shaped by the media and the strategy they used to achieve their objective. The media propaganda is key major part of media operation and is used to accommodate as well protect the agenda of the elite.IntroductionThe American culture of today is communicated through media. Media is the most powerful and influential force in the country. The media are powerful agents of socialization and they set the standard that majority follow. The power giving to American media has allowed them to be very effective using propaganda as strategy, the media tend to say they serve to relieve social conflicts into minimum. We clearly see that the media promote social conflicts by separating class. The image that media has created in the mind of masses has economical, psychological and sociological impact the masses.The intent of the media is to satisfy their own agenda, not to inform and entertain. They been very successful using this strategy, more of their agenda less of the masses interest. Richard Cohen once said ââ¬Å"We are going to impose our agenda on the coverage by dealing with issues and subjects that we choose to deal with.â⬠Propaganda is form of communication that attempt to influence the attitude of the community towards some cause or position by presenting only one side of an argument. Propaganda is widely spread throughout the media to create chosen result in audience attitudes. Media main objective is to influence the attitude of the people. The audio visual media such as television, radio, and sound motion pictures means of communication are available to the psychological operator.Their effectiveness is based on seeing and having the persuasive message. These medium provide an excellent means of persuasive message. Television projects the sense of sight, adding the element of motion, like motion picture, it combines sight, sound and motion. Television is an immediate effect, it places the viewer is two locations simultaneously, creating the illusion of participating in a distant event. The transmission of T.V overcomes illiteracy, audience need not be able to read.The Psychological media propaganda advantage helps the media through television bring people in global separate locations together by exposing then visually to the same ideas and concepts. Psychologist Hadley Cantril and Hazel Gaudet, led us to some valuable discovery afte r October 30 1938 when radio broadcast war of the world? As a result of this broadcast there was a national panic for all to see the effect of media propaganda. While many panic during the broadcast, some remain calm and collected. The people that were not panic displayed what psychologist called a critical faculty (pg589). The lack critical faculty was the lack of the ability to create a framework in which to check if information were true.The people that lacked critical faculty are the low income bracket because of limited sources of information. A psychology study conducted by Cantril, along with Gaudet, H, the model which accounted for how movies influenced children. The study of media effect has spawned many functional theories today such as Agenda-setting theory, cultural imperialism theory. The powerful influence of media is revealed through agenda setting the ability to tell the masses what issues are important. Many have been concerned about the psychological effect of medi a as far back as 1922. Media has the power to presents images to public through propaganda. Which McCombs and Shaw investigation ofà presidential campaigns in 1968, 1972, and 1976. In the findings, they concluded that the mass media psychological a significant influence on what voters considered to the major issues of the campaign.The agenda- setting allowed the media not to reflect reality, they filter and shape it. They also concentrate on few issues and subjects leads the public to view those issues, as more significant than other issues. The time frame is the most important aspect of this phenomenon. Bernard Cohen (1963) psychology effect of media, they may not be successful in telling people what to think, but it is stunningly successful in telling its readers what to think about. Lastly, the western nations dominate the media around the world.The western nations used cultural imperialism to impose their western views through media on third world countries. They simply shape and control third world destroying their native cultures through the effect of media propaganda. There are several different theory that provide evidence of this. In as much as the third world countries continue to broadcast western civilizationââ¬â¢s programs, then these countries will always believe they should act, think and live as westerners. Clearly it is widely seen how media propaganda has impacted our lives psychologically.Over the past generation, it has become very clear that the U.S mass media is a major influential voice in the U.S society. Edward S Herman once said media operate in systematic propaganda model. The media serve to mobilize support for the special interests that dominate National, State and Private activity. Propaganda is not the only function of the media, however it is a very essential aspect of their overall service. Certainly in a capitalist society and major conflicts of class interest. The media function to serve the large propaganda requirements of the elite. The media have consistently promote the agenda of the elite, particularly in U.S.First thing to consider in the economic effect of media propaganda is the ownership of the media is among a handful the largest profit corporations in the world. Many of these corporations have a comfortable size of interest in U, S economy. Objectively, their needs to remain profitable corporation severely influence the need operations and major content of media broadcast. Subjectively, the self- interest of the handful corporations as become the operation of the media. Second advertising, has colonized the U.S media and is alsoà responsible for most of their generating income.Third media are drawn into symbolic relationship with powerful sources of information by economic necessity. Media depend upon news provided them by corporation and government sources and due to this fact they are pressured to follow corporate agenda. Whenever the wealthy right-wingers were dissatisfied with poli tical media coverage. They make sure that they send a clear message of their displeased. The ideology of double standard of the media propaganda work effectively.For example the media treatment of murder coverage or report is based on if it is a worthy victim or unworthy victim, which majorly depended on their relationship to the elite interests. The news coverage of Vietnam War and the development it appear as if the media were opposed to the war. Contrary to the image the media portray, they continued to present the War in manner consistent with the interest of wealthy till the very end. This provide a good example on how media propaganda operates to maintain economic agenda. For news to be worthy of coverage it would have to meet the elite requirement and it must be something the media can sale.It very certain that all these facts have major impacts on how media deliver news to the general public, the economic effect of media propaganda determines what event or incident gets medi a coverage. It is a system that continues to develop a systematic approach of how to protect the interest of the elite without making it obvious to the public. We believe that the media exist to inform and entertain, however the reason for the program will watched on T, V is to keep us interested till the next paid commercial. The more will considered the economic effect of media propaganda the more will discovered that its centered around the agenda of wealthy folks. The agenda of the elite is what is propagated by the media, the generally public received it as the truth follow. The Sociology perspective of the media is also an important aspect to consider.If the powerful are able to fix the premises of discourse, to decide what the general populace is allowed to see, hear, and think about and to ââ¬Å"manageâ⬠public opinion by regular propaganda of their own strike in an issue or immobilized by effective propaganda the media will serve elite interest uncompromisingly (Herma n,1996). It very essential to look different sociology perspective of media propaganda and how they influence ourà society. Functionalist believe that media propaganda contributed to the benefit of the society. Charlie Wright (1975) was able to identify ways media contributed to society. He said media coordinate and correlate information that is valuable to the culture. People gather in groups to watch, they talk about what they see, and they share the sense that are watching something special (Schudson 1986).Functionalist view media propaganda as an important function in society. It is the media to influence social uniformity on bigger scale. Media propaganda has been accused of creating dysfunction. Postman (1989) argued the media culture undermines the educational system. Conflict perspective claim that corporation use media propaganda to satisfy their own agenda. Sitcoms and News coverage are not created to inform and entertain, however they are to keep our interest to the nex t paid commercial. This perspective view media as conduit for social coercion. The owners of media use programing and advertising to influence certain and targeted social class.Whatever agenda or trend they introduced through media is the public mimicked, the media maintain dominance and remained major influential force in the nation due to the fact that they were use propaganda very effectively. From the conflict perspective, modern day media are instruments of social control,(Sullivan 2007) while interactionist and functionalist agree that media propaganda is necessary, conflict perspective view media propaganda as necessary evil. The media propaganda is used as an instrument of social control and also an effective way to carry out their agenda.Interactionist perspective, media propaganda is used to define and shape our definitions of any given situation. This perception of reality seems to come together as daily value and cultural change. The definition of American in the 50s is definitely different what we see expect today. The way the media portray family is the set standard that majority of society would consider acceptable. The effect of the media propaganda is powerful that social acceptance is solely dictated and depended on what the media approve. The symbols that the media present to us will represent what is acceptable and proper. So anyone that does not identify with the symbols are considered to be an outcast.The media propaganda create a perfect society illusion that the masses strive to emulate. You have athletes, celebrities and models promoting clothing, brand that vast majority cannot afford. To consider to be part of the elite classà society you have to identify with those things. Many people have lost their own identity trying to meet up with media expectation of them. Many also get into huge debt due to the fact that the image of happiness the media portray is things you can afford to buy with good credit. The interaction between the ma sses and the media is symbolic. They serve their own agenda, whenever the public interact with the media is to acquire information or to be entertained, however whenever the media interact with the public is serve their own agenda, which is the agenda of the elite groups of individual that runs them.The agenda of the elite is to impose their ââ¬Å"Willâ⬠on the masses and make money of it. CEO of Walt Disney, Michael Eisner once said ââ¬Å"We have no obligation to make history, we have no obligation to make art. We have no obligation to make a statement. To make money is our only objective. The media interaction with general public is symbolic because it revolved around money, money is the symbol that connect the media with the public.ConclusionThe media control the country using propaganda and illusion of choice to achieve their agenda. The 6 media giants control 90% of what we read, watch, listen to and anything outside these sources is consider not to be credible. The info rmation that we received on daily basis are controlled by six individual who run these companies. The media form and shape the society culture, reality and acceptance. They not only function to promote the agenda of the elite, they impose the culture accepted by the elite as set standard for all. The instrument that the media use to control society is propaganda.The media used the illusion that they exist to inform and entertain, however they existed to serve the agenda of the elite. They use different avenue to capture and change the public minds in order to achieve their own objectives. Our culture in America today is what the media say it is, Social conflicts are promoted by the media, separating public into different classes and holding one particular groups as the set standard of the rest. Finally the new coverage or any information we gathered through media is the mediaââ¬â¢s imposed agenda.

influences on govenment essays
influences on govenment essays Our governmental system is influenced by a number of "inputs" and factors that shape the outcome of political movements and decisions. These "inputs" include public pinions, political parties, interest groups, and the influence of mass media. They influence our government directly as well as indirectly. Not to mention, that our government also uses these "inputs" for its own benefit. The main issue that forms governmental decisions in a democracy is of course the public opinion. In order to be eligible to run for an office in our governmental system, one must be elected by the people or a representative thereof, and to achieve this task one must listen to and obey the public's opinion. Therefore, the theory of democracy is most purely applied through election on behalf of the public opinion. Another important factor in our system of government are of course our political parties. Parties enable the citizen living in a democratic society to establish a connection to governmental action and lead policy-making to his benefit or liking. Furthermore, a citizen can participate in society quite easily, since 2 party platforms which clearly indicate a parties goals and preferences. However, this democratic ideal does not always prevail. Parties can be influenced or even manipulated by people who contribute great amounts of funds to the party to have their own personal political wishes fulfilled which do not necessarily have to benefit society as a whole (power elite theory). Interest groups account for an additional 'mover' in Washington. This political devise provides a supplement to our citizens broad area of interests. Since the American People can only choose between two main parties. Therefore, certain issues might not come to political debate. Interest groups fill this gap and thus withhold the theory of democracy. Yet, 'Big Business' has also found this devise to help fulf ...

Baldwin Relationships essays
Baldwin Relationships essays This story represents the effects of a parent child relationship and how it impacts the child even after the death of his parent. Baldwin did not know his father very well, mainly because they shared different views about life. His father knew that the world had opportunities but felt they were only for the white person. Baldwins father was the first generation to be a free man. His father along with thousands migrated to the north after 1919. Baldwins father experienced first hand what is was like to be a slave and how the white people treated the blacks. This certainly affected how Baldwins father felt toward the white person. Baldwin, however, did not experience what it was like to be a slave. Baldwin and his father never really connected as father and son. His father was a harsh man which made his son afraid to approach him. Baldwin says, When he took one of his children on his knee to play, the child always became fretful and began to cry; when he tried to help one of us with our homework the absolutely unabating tension which emanated from his caused our minds and our tongues to become paralyzed, so that he, scarcely knowing why, flew into a rage and the child, not knowing why, was punished. (53) This passage shows how Baldwin and his siblings were scared to be around their father. There was so much anger built up inside their father that whenever he would try to help one his children, they would become frightened and too scared to say or do anything, and that made their father even madder. Baldwin was afraid to have any of his friends over to his house because his father was mean to them. Baldwins father would tell his friends that they were in a league with the devil and intended to rob them. When his father did this it made Baldwin hate his father and not want to be around him. Baldwins father hated and feared most people he met. This fear and hatred even we...

Global Warming Threats and Solutions
Global Warming Threats and Solutions Introduction There is little doubt that our earth is undergoing a gradual increase in temperature: global warming is real. Baffling statistics by the Intergovernmental Panel on Climate Change (IPPC) indicate that the earthââ¬â¢s temperature has risen by roughly 0.6 degrees Celsius, the highest since the mid 1800s, further reports indicate that the duration from 1997-2003 were the hottest years ever recorded.Advertising We will write a custom report sample on Global Warming Threats and Solutions specifically for you for only $16.05 $11/page Learn More Worst is yet to come as the United Nations committee on climate has predicted a temperature rise of between 1.8 to 6 Degrees Celsius by the end of the century which enough to melt all ice and polar caps (IPPC, pg. 2). This would spell disaster as many countries, cities and towns will be submerged, including the Netherlands and New York City. The threat is real and unless we act appropriately, almost half of a ll earth will be under the sea at the turn of the century. Natural or man-made? In the past few years, the threat of global warming has appeared real and this has led to debates over who or what was responsible for the condition. The media, politicians and the general population have been divided on this topic. Skeptics argue that human activities man is not the leading cause of global warming, they assert that climate will change continuously, as it has in the past, human activities not withstanding (Singer, pp. 1). However, to understand the actual cause(s) of global warming, we need to understand how the process occurs. Global warming is mainly contributed by Greenhouse gases, this consists of water vapor, carbon dioxide (CO2), methane (CH4), and Ozone. The highest contributor of these gases to the atmosphere is man. The Industrial Revolution had greatly increased the amounts of CO2, CH4, chlorofluorocarbons (CFC) and nitrous oxide in the atmosphere with levels of CO2 and CH4 inc reasing by 40% and 150% respectively since the mid 18th century. These values are the highest during the last 650,000 years, the last time CO2 levels were higher than this was roughly 20 million years ago (IPPC, pg. 1). The high levels of CO2 have been caused by burning fossil fuels and de-forestation, man is the cause of both (Simon et al, pp. 79). A recent study examined more than seven million studies of temperature, salinity, and other factors that affect the worldââ¬â¢s water systems collected by the US National Oceanic and Atmospheric Administration and compared them with predictions from computer simulations.Advertising Looking for report on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More The study found out that natural occurrences in the atmosphere, such as volcanic eruptions and the sunââ¬â¢s activities, could not sufficiently account for global warming. Simulations based on human activities, h owever, exactly corresponded to the observations (Henderson, para. 6). The study eliminated all possible causes of global warming and was left with one culprit: man. The study also simulated past and future consequences of global warming and the findings were nothing to be admired and cannot be merely dismissed. Global warming could cause disastrous effects in the future, for example, a study undertaken by a team of scientists led by Ruth Curry of Woods Hole Oceanographic Institution found out that 20,000 square kilometers of ice in the Arctic melted between 1965 and 1995 (Henderson, para. 10). Continued melting at this rate could destabilize the ocean currents that keep Britain warmer than other European countries. Solution The evidence that man is responsible for global warming is admissible, therefore, solutions to global warming lies with us. The solution to global warming is quite simple, one does not have to make long journeys or spend large amounts of money, rather, implement ation of the strategies that are outlined below will assist in averting this menace (Pearson, para.4). The first step is energy efficiency. This is a very large topic and covers almost all facets of energy use contributing to global warming. Energy efficiency involves adoption of energy forms that limit global warming, also referred to as alternative or renewable energy. The three main sources of these energy forms are the sun, tidal and wind energy. Other forms include hydroelectric, geothermal, diesel and biodiesel energy forms. Solar and wind energy present us with a greener and more environmentally friendly energy options, besides being renewable, they can be harnessed from almost anywhere on earth. Another simple process of keeping global warming in check is to plant trees around the house, school or in any open field. As simple as it may sound, this goes a long way to eliminating the Greenhouse gases from the atmosphere, making the earth cooler. Other outdoor activities such a s using bicycles or walking over short distances instead of using a car are very pivotal in reducing the levels of Greenhouse gases. We should strive to recycle materials around the house, especially non-biodegradable types such as packaging material. Plastic packaging bags can be re-used to reduce the environmental damage related to these materials. The manufacturing process of plastic bags also leads to an increase in CO2 in the atmosphere.Advertising We will write a custom report sample on Global Warming Threats and Solutions specifically for you for only $16.05 $11/page Learn More Conclusion If everybody follows these rules, we would be helping ourselves and even the future generations by preserving the earth. If all of us take a role in preserving the earth, the cumulative effect would be significant to cause a drop in the level of Greenhouse gases, hence the earthââ¬â¢s temperature. Henderson, Mark.

The Immortal Life Of Henrietta Lacks ( summary of part 3 of the book) Essay
The Immortal Life Of Henrietta Lacks ( summary of part 3 of the book) - Essay Example Naturally, doing this would mean that the family would come in contact with the researchers as well as the knowledge that Henriettaââ¬â¢s body biological matter was still very much alive and being used for medical research. When the medical professionals contacted the family to obtain consent to take blood samples in order to track the genetic markers, a Chinese graduate student was employed to do this and was not fully able to transmit the necessary information to the family. Upon a better understanding of precisely what was going on, the family divided between those that sought to understand what specifically was being done to Henriettaââ¬â¢s cells and how and those that wished to be compensated for the large amount of money that had been made from the biological matter that had already been sold by a host of medical labs. Likewise, the story goes on to discuss the means by which new and developing laws would affect the treatment of an individualââ¬â¢s biological matter bo th before and after oneââ¬â¢s death. The author relates the case of an individual who signed a consent form to give up any and all rights to his spleen and the subsequent cells that might be cultured from it. In this way, the story tracks the developments of medical law and the ways in which biological and tissue began to develop a strict set of laws that governed their usage. Returning the story to the Lacks family, the author relates how Deborah, Henriettaââ¬â¢s daughter, remarried and Zakariyya was in and out of prison and only able to hold work intermittently. Furthermore, the additional children suffered from narcotics abuse and minor run ins with the law. Meanwhile, Deborah continues to research what has happened to her mother and how the cells are being used. A subsequent documentary by the BBC helped to acquaint the family, due to the fact that they were interviewed, regarding precisely what had transpired with the HeLa project. Lastly, the author relates the way in wh ich the legal back and forth between Johnââ¬â¢s Hopkins and the family served to add even more stress and concern to the family with regards to how they felt they had been manipulated from the very start. Response: This particular section of the book is of vital importance as it is the part in which the family begins to come to a more full and complete realization of what the HeLa project actually entailed as well as the ways in which the medical community would resort to intimidation and threats of lawsuits in order to keep them quiet and complacent with regards to the injustices that had been done in the past. For this reason, the author relates a sad story of how lawyers such as Colfield sought to take advantage of the situation and exploit the family while all the time feigning to be pursuing the case out of a mutal shared interest in seeing justice done (Skloot 182). This introduction to the way the legal system in fact worked against rather than for them as well as how the legal system had been powerless to help to define the ways in which the medical community could operate the HeLa project was just further evidence to the family that they were outclassed by a wily system that sought only to exploit their family member for profit and gain while at the same time denying any of the proceeds of such a project

Aviation Psychology - Research Paper Example A quantitative study focuses more on statistical data analysis to generate numeric results. Sen (2012) states, ââ¬Å"Qualitative Research is usually non-statistical analysis and in case of Quantitative Research Statistical data is usually in the form of tabulationsâ⬠. Doing quantitative study, researchers identify the relationships that exist between independent and dependent variables to know the effect of one variable on the other one. Quantitative study focuses more on gathering data using large-scale surveys. In quantitative studies, researchers are usually independent of the research and they analyze different variables to determine their relationships by doing a proper statistical analysis. In quantitative research, researchers gather absolute data in order to generate numeric results based on statistical analysis of data. ââ¬Å"Quantitative research involves gathering data that is absolute, such as numerical data, so that it can be examined in as unbiased a manner as possibleâ⬠(McGuigan, 2011). In quantitative research, researchers identify the association and links between independent and dependent variables in order to determine how rise or fall in one variable affects other variable. In a quantitative method of research, researchers are independent of the research and gather data about the variables associated with the research to determine their level of dependency or association with each other based on a comprehensive statistical analysis. Another reason for choosing quantitative research design is time efficiency. There is a huge time difference between compiling a theoretical research and a numeric result. It takes less time to compile quantitative resu lts of a study as compared to qualitative results, which are theoretical in nature.

Solar Power Industry - Essay Example The success of U.S oil production company, Shale, has caused various producers sleepless nights. GCC countries are greatly concerned with this ââ¬Ëunhealthyââ¬â¢ trend that is hurting their economies badly. Augustine (2013, December 9) reports that many cities and countries in the GCC such as Doha, Qatar have undergone massive development due to high oil prices. This article piqued my interest as it focuses on the future and affects every country. Also, it spots various loopholes in the developing countries. Further,it proposes various measures that the young citizens of various developing countries should put to task to ensure their respective countries are at par with global standards in various sectors such as technology, education, and the service industry in the future. In an effort to explore the on-surface effects, as well as the extended market effect, I will explore various microeconomic concepts such as the theory of the firms, consumer theory, and the demand and supply side of the market. The ease with which new firms enter market imposes great threat to existing firms and the future of such industry (Perloff, 2011, p. 154). This can result to possible exit of other firms in the event a firm that enjoys great economies of scale engages in unhealthy business competition. Shale company successful positioning in the market due to high technology it employs in mining has made it increase its output with the current level of inputs. It experiences increase return to scale due to efficiency with which it conducts its operation. Consequently, it can decide to lower the prices of its product and this will impact negatively on the future of other firm, and various positions they hold in the market.

The essay emphasizes the need to make mental health services easily accessible to service users that belong to the selected social class i.e. black individuals suffering mental health issues. Social exclusion refers to the marginalization that is experienced by certain disadvantaged classes of a society due to their social, educational, political, and economic or health backgrounds. Individual belonging to such classes are generally deprived of access to resources that are otherwise available to all other classes of the society. One of the most common themes in this regard is income or social inequality.

Poverty Economics Research Paper Example | Topics and Well Written Essays - 1750 words
Poverty Economics - Research Paper Example The model of trickle-down effect of growth is found to be prevalent in practice in the real world. Under this model, the benefits of growth are mostly savored by the upper and middle classes of the society. The lower middle class and the grass root level receive very little benefits of this economic growth. This is due to the fact that there is serious problem of income inequality in most of the economies in the globe, particularly in the developing countries (Altmann et al., 2013). All the sectors in the developing economies are not equally developed and there is huge inequality in income in the countries. In the concerned article, the Chief economist of World Bank has mentioned that the Bank has placed two new objectives that it would strive to achieve. These two goals are ââ¬Å"ending extreme and chronic poverty in the world by 2030, and promoting shared prosperity, defined in terms of progress of the poorest 40% of the population in each societyâ⬠(Basu, 2013). ... factors that affect this growth rate are rapid technological development, improvement in productivity and the lowering in the number of people living below poverty across the world. During the 19th century and also in the first few decades of the 20th century, over 1.2 billion people in the world used to live below the poverty level (the poverty line is set at $1 per day). Currently, this percentage of population has fallen marginally. According to the theory of poverty line, the people living below poverty line have the purchasing power of less than $1 dollar per day. Additionally, it must be noted in this context that more than half of the population of the world lives below $2 dollars per day. The variables that measure poverty are under nutrition, poor health condition, poor level or absolutely no literacy, environmentally degraded and unhygienic living condition, low or no access to essential things in life (such as clean water) and lack of protection of fundamental freedoms or rights. Poor people all over the globe are characterized by the living condition in slum areas and under nourishment. Scholars and economists have univocally agreed that poverty is integrally linked with inequality in income distribution (Naranpanawa, Selvanathan & Bandara, 2013). One commonly used method of measuring the personal income statistics is the Lorenz curve. The Lorenz curve helps to analyze the percentage of income against the percentage of income recipients. The further the line is from the diagonal, the greater is the degree of inequality. The following diagram illustrates the workings of the Lorenz curve. Figure 1: Lorenz curve (Source: Anonymous, n.d.) The further the curve bends from the diagonal, the greater is the inequality in income level. The area between the two

Indeed, as certain as death and the effects of death could be certain. Certainly, death may have different and diverse effects on different people in the community and society. Indeed, death creates an environment of desperation and decay. In the Rashomon story, the different effects that death may have on different people are brought to light. The story descriptively covers the story of a black servant thrust by fate and death into desperation to survive after losing a job. Interwoven with the black servantââ¬â¢s fate, the effects of death are observed through the fates of the senile woman and the deceased young woman. To begin with, huge numbers of deaths reported at a place may strike as a catastrophe making people flee. For instance, the rampant deaths in Kyoto made people leave town and hence ââ¬Å"the Rashomon sheltered at least a few othersâ⬠from the impounding rain (Iglesias, Michael and Linda, 1). A few people in the town are explained by ââ¬Ëone calamityâ⬠¦In recent yearsââ¬â¢ (Iglesias, Michael and Linda, 1). As a result, the Kyoto city registered massive decay following the exodus. The city also ran into a state of desperation, decay and decline. For instance, ââ¬Ëpeople [smashed] Buddhist statuesââ¬â¢ and piled them along the road tucked in ââ¬Ësilver and gold foils and paint flecksââ¬â¢ selling them as firewood. Indeed, the story further expresses the turmoil that the whole city experienced, yet ââ¬Ëno one botheredââ¬â¢ to care for the Rashomon. Worse still, rampant cases of death coupled with city decay attract wild animals and other scavengers. For instance, the exodus resulted to dilapidated structures that offered an ideal abode for badgers and foxes. Thieves also took cover in the cityââ¬â¢s backstreets and dilapidated structures. Wanton social decay in the Kyoto city inspired the living to litter and dump ââ¬Ëcorpses in the upper storyââ¬â¢ (Iglesias, Michael and Linda, 1). As a result, the entire neighbourhood became ââ¬Å"an eerie place everyone avoided afterâ⬠sunset (Iglesias, Michael and Linda, 1). This also attracted crows that ââ¬Å"flocked in great numbersâ⬠(Iglesias, Michael and Linda, 1). The scavengers created a petrifying and grotesque scene with their pecking of the dead flesh while their white droppings created an ugly scene. Notwithstanding, rampant deaths coupled with human migration render others unemployed. For instance, the black servant sheltered from the impounding rain at the Rashomon, ââ¬Å"had been dismissed from service some days earlierâ⬠(Iglesias, Michael and Linda, 4). Regrettably, his master had dismissed him after serving dutifully for several years. Therefore, unemployment represents ââ¬Å"one small consequenceâ⬠of the wanton deaths in Kyoto city (Boer, and Donald, 14). Besides, the black servant sat idly at the Rashomon ââ¬Å"waiting for the rain to endâ⬠unawares of what to do once the rain stopped. He was desperate to survive and find a place to sleep without the prying eyes. Indeed, ââ¬Å"he was determined to find a way to remain alive for an extra dayâ⬠by doing all that he could (4). As the adage goes, idle minds bleed evil thoughts and hence, the black servant thought of thievery to survive. Although thievery was against his believes, and ââ¬Å"he could not find the courageâ⬠to decide to go into thieving. Death inflicts both bodily and mental torture. The black servant confronted evil minds and ideas, but he concludes the same. The freezing evening chill was harsh against his body and he had to ââ¬Å"drag himself to his feetâ⬠(Iglesias, Michael and Linda, 5). Worse still, the blowing evening wind was unmerciful to the freezing black servant. Constant cases of death at a decaying city as Kyoto result to careless dumping of human corpses. Often, the corpses are piled at a segregated place. True, a place with piled up decomposing human corpses is not a haven or paradise. Therefore, it is scary and unorthodox to scour through the piles plucking off their hair. The image of a ââ¬Å"scrawny old woman, white haired and monkey-likeâ⬠scouring through rotting human corpse is also pathetic and weary. However, the black servant inspired by the need to remain alive and curiosity weathered the petrifying smell and flight and approached the woman. Incessant deaths throw people into a state of panic and desperation. The scrawny old woman endured plucking human hair to survive. She plucked the hairs to make a wig perhaps to weather the harsh weather or sell and make a living. The constant desperation in the city wore on her heavily and her faced wrinkled, her eyes reddened and became predatorily sharp while she cawed like a crow in her voice. It is obvious that the perpetual deaths had hardened her body, spirit and soul alike. She was contented with plucking off and unaffectedly arguing that the corpses deserved her wrath. Through the old womanââ¬â¢s anecdote, readers learn that desperation as a result of the deaths drove people into different, diverse and complicated business trades. For instance, in her justification, the scrawny old woman reasoned that the young woman ââ¬Å"cut snakes into four inch piecesâ⬠and sold them ââ¬Å"like fish at the palace guardhouseâ⬠(Iglesias, Michael and Linda, 8). The old woman further reveals that the ââ¬Å"fishâ⬠was a delicacy and the guards ââ¬Å"bought it for every mealâ⬠(8). Therefore, death intervention was a necessary evil to the young woman because she stopped selling snakes. The act inspired the black servant to strike and strip the old woman robbing her of her robe despite the cold. In the event of death, a trail of human anguish, torment and desperation ensues. Constant and perpetual deaths results into social decay, ruin and migration. As a result, grotesque, ugly and petrifying scenes occasion every corner. Thieves compete with wild animals and scavengers for structures and corpses to feed. Above all, humanââ¬â¢s humane sense disappears and selfishness settles all as a result of death.

Change Leader Jack Welch Business Essay
Change Leader Jack Welch Business Essay This paper will take a closer examination at how Jack Welch changed the General Electric Company using a transformational leader style. Welchs strategic were to change the value system at General Electric. Moreover, Jack Welch is considered one of the greatest leaders in corporate business in the 21st century. What has made Welch so successful is his development of a modern model design for his company. Welchs model has escalated the growth of General Electric profits billions dollars in a span of an about twenty years. There is no corporate leader to this date that has shaped the value of their company for shareholders much and as rapidly as Jack Welch has. He created a market that had share running high to make the company worth billion. Welch transformed General Electric, a key giant company during the industrial age in American into thriving company modern day company that is highly competitive globally. The key to all of Welchs success is his ability to relate to people in an in formal matter. He has protected communicating across the organization informally with his chain command and subordinates alike. Moreover, Welchs charismatic leadership style and his aggressiveness when he attended meeting and events has given him the ability to communicated effectively with a very large number of employee across the entire organization. Jacks Welchs Background Jack Welch was born in 1935 in Salem Massachusetts (Abetti, 2006). Welch received his undergraduate, Masters And Ph. D degrees all in the field of Chemical Engineering. Moreover, in 1960, Welch began his career with General Electric as a Chemical Engineer. According Abetti (2006) to the General Electric Company has been a part of history as far back as the development of new light technology starting with Thomas Edison becoming one of the largest organizations around the World over. However, as time went by General Electric begin to make their employees push in the development of product to in front of their competitive. One executive who had the leadership ability to do this was Jack Welchs (Abetti, 2006). His leadership is considered true transformation leadership. He created a vision base on organization values. Welch efforts has help reform the structure of General Electrical management by cutting the middle management staff members. Jacks Welchs Strategy Jack Welchs strategy was first getting his followers to see the big picture where General Electric was heading in the future. The whole time as CEO, he delivered his messages repeat to reinforce them. Them by handwritten directly to the employee this method has inspired many of the organization. Welch is known to spend most of his time in dealing with issues with employees. He personal knows over 1000 employee in the at all level in the company and this is by a first name bases (Amernic, Craig, Tourish, 2007). Next, he created a completely new organization culture by restructuring the hierarchy of nine management levels in a simple structure that was more cost effective. Welch new that many of his senior leadership would question his policies. However, the key to his plan was to stick with the plan and policies, regardless how subordinates felt. Finally, Jack Welch knew there must be some high risk taken behavior in order for changes to take place (Amernic, Craig, Tourish, 2007). M oreover, he obviously knew, how far to take risks. The strength and weaknesses were in leading the organization. Never the less Jack Welchs strategy created the standard and benchmarks to instill in his subordinates change at General Electric. Jack Welchs Charismatic Style Indeed, there is no doubt that Jack Welch had displayed a substantial level of charismatic leadership during his reign at the General Electric. Jack Welch has shown his ability as a transformational leader by continuously trying to inspire and inspire his staff members to be the absolute best that they can be. There are four factors that Welchs has display he possessed to be a transformational leader: idealized influence (factor 1), inspirational motivation (factor 2), intellectual stimulation (factor 3), and individualized consideration (factor 4) (Northhouse, 2010).Under the term, idealized influence the leader is considered a role model for employees to follow. Welch provided his workforce with his vision, so that they can have an obtainable. Jack Welch is known for having a personality that is out spoken and his has be credited by employees has being the one who spurred growth for general Electric. Welch has conducted idealization influence by decentralizing the entire organizati on and giving his lower level workers some say so in the decision making process in the companyà Inspirational motivation (factor2) can be simplyà considered as inspiration (Northhouse, 2010). A change leader expects their followers to meet high expectation. Welch had high expectations for the entire business unit in General Electric. He challenged his employees to function to be number one or two in the organization. If any of these units fail to reach these objectives, they would be shut down or put up for sale by Welch. Moreover, this motivated the workforce to maintain Welchs Goal, because they all had a shared value. Intellectual stimulation (factor 3) Transformation leadership must be able to allow the subordinate in became innovated and not be afraid to challenge their current beliefs to develop a better approach to a process. Jack Welch management techniques were so successful that other organization begins to follow his practices in management (Northhouse, 2010). One particular practice in manage that welch was known. Individualized consideration (factor 4) represents the leader who provides a supportive climate in which they listen carefully to the individual nee ds of followers (Northhouse, 2010). Moreover, Welch was thought of by his staff as an innovated leader for the individual. Some critic believe that welch management practice were cruel, but in all actuality Welch use plenty of tact and careful planning when it came to down to laying off his employees. Furthermore, many thought that he was being fair because he lay off worker with very bad work performance and even than he gave these employees, a very generous severance pay. Welch believes that his lever level employees should be more involved in the development of General Electric newly evolving organizational culture. They were instrumental in the development of general Electrics Mission Statements. Welchs Techniques created a sense of unity and Sense of belonging in the organization. In addition, Welch always took many trips to the numerous business unites in the company. Conclusion Jack Welchs leadership principles have changed the corporate model, and will be used for many years to come. Welch is well known by many to cut down on staff at the middle management level that job performance. Jack Welch made many milestones at General Electric here is just a few: According Kieser Hegele, (2001) to Jack Welch, increased General Electric values of shareholder stocks to over 200 dollars a share (Kieser Hegele, 2001). The profits for General Electric soared to more than $400 billion in revenues in one year. (Kieser Hegele, 2001) He had a specific focus on development of the employee; begin the process at the hiring stages in the organization until they reach form of leadership position in the company. Finally, one of the main points to the success of Jack Welch tenor at General Electric is his attitude toward communicating constantly the value of the organization and letting employee share their ideas. Jack Welch allowed this practice to happen so that his manger co uld have a better understanding of their employees behavior to improve the overall organization productivity. Welch will place General Electric Company into ever-higher levels of success, After Welch leaves the organization.

EVALUATING NORTH AMERICAN HEALTH SYSTEMS Essay -- essays research pape
INTRODUCTION à à à à à Compensating the affairs of economic efficiency with the demands of sociopolitical rights is a constant source of tension in Canada and the United States alike. In no other element is this tension more apparent than in the group of complex markets we call the health care system. à à à à à Canadians have been fortunate enough to receive a universal health care system for nearly forty years. This is a single-payer system funded by the governments, both provincial and federal, but at what costs? Is health care not unlike any other commodity, or is it the privilege of every citizen? Health care has elements of common economic behavior, however, there are also certain social values associated with it. It is this struggle of defining what health care is that causes such anxiety among economists. The Canadian health care system is slowly crippling the economy, and reforms must be devised to preserve the pride of Canada; our health care system itself. à à à à à The pluralistic health care scheme of the United States, as well, has serious socioeconomic implications, and American policy makers are looking toward the model of the Canadian system for answers. Both the United States and Canada must reform health care policy, but to what extent? Obviously these questions cannot necessarily yield clear, concise answers, however they will provide insight into analyzing the current and proposed systems of health care. à à à à à Certainly if Canada is to maintain a high standard of care it must adopt an economically efficient, revenue generating system. Moreover the United States must adopt the single-payer system of Canada while still retaining a strong revenue base. This paper will discuss the strengths and shortcomings of the Canadian health care system, and how health care is a sociopolitical enigma. Furthermore, how the single-payer system is the only realistic response to the growing inadequacies within the American socioeconomic status. CANADIAN HEALTH CARE STRUCTURE à à à à à Serving as a general background in its appraisal, it is necessary to outline the history and the ambient factors of the Canada health care that is so sought after by the United States. The Canadian health-insurance program, called Medicare, is administered by provincial ... ... and this tension is prevalent in the health care system. A basic economic concern is whether health care is like any other commodity. The health care industry can be analyzed with economic frames of reference: wealth, risk aversion, efficient transfers, and utility. However, there are certain symbolic elements of health care that cannot be easily measured. Cultures have fundamental beliefs that encompass the valuation of life and health. Bearing this in mind, it would only seem realistic that there is some sort of right to health care. à à à à à Nowhere in the American Constitution is it stated that an individual has the right to some basic set of health care services, however, there are certain undefined responsibilities the government has. It can be argued that the Declaration of Independence supports the right for each and every citizen to have the basic care needed to sustain life so as to exercise oneââ¬â¢s liberty and to allow the pursuit of happiness. It has been argued that there is a common-law right to equal services, a right of equal access to basic services: such as drinking water. Furthermore this right extends to all citizens and is beyond the reac

The Issue of Experiment in Mathematics Essay -- Math Philosophy Philos
The Issue of Experiment in Mathematics ABSTRACT: The issue of the status of mathematical knowledge a priori or a posteriori has been repeatedly considered by the philosophy of mathematics. At present, the development of computer technology and their enhancement of the everyday work of mathematicians have set a new light on the problem. It seems that a computer performs two main functions in mathematics: it carries out numerical calculations and it presents new areas of research. Thanks to cooperation with the computer, a mathematician can gather different data and facts concerning the issue of interest. Moreover, he or she can carry out different "tests" with the aid of a computer. For instance, one can study strange attractors, chaotic dynamics, and fractal sets. By this we may talk about a specific experimentation in mathematics. The use of this kind of testing in mathematical research results in describing it as an experimental science. The goal of the paper is to attempt to answer the questions: does mathematics reall y transform into experimental or quasi-experimental science and does mathematics vary from axiomatic-deductive science into empirical science? For thirty years the computer has been used by mathematicians to solve some problems. Automatic proving of theorems, proofs obtained with the aid of the computer for the theorems whose traditional proofs are not known (e.g. the four colour problem), using computer graphics, observations of different systems behaviour with parameters changed, solving differential equations, integration ââ¬â these are only a few possibilities of computer application in mathematics. Using the computer created new work conditions for a mathematician, at the same time bringing about severa... ...objects. Because there can be shown an analogy between mathematics and natural sciences. Physical objects are recognized in the process of our experiencing materialistic reality. The experiment in natural sciences can be defined as a dialogue between the learning subject and the nature, which exists objectively. If we treat the experiment in mathematics in similar way, then there has to be two interlocutors: a mathematician and the field of mathematical objects, subjected to its own rules independent on the researcher's will. Notes (1) B.Mandelbrot in the context of using computer graphics states that: "The eye deserves to be made an integral part of the process of scientific thought" ("Opinions", Fractals 1(1993)1, p.120). (2) Those examples are quoted by G.Polya in "Mathematics and Plausible Reasoning", vol. I, Princeton-New Jersey 1954, p. 90-100, 168.

College Stress Essay
Jackââ¬â¢s heart pounds as he casts panicked looks around the classroom. He doesnââ¬â¢t recognize the professor, he doesnââ¬â¢t know any of the students, and he canââ¬â¢t even figure out what the subject is. In front of him is a test. At the very last minute his roommate awakens him. Itââ¬â¢s only another anxiety dream. The very fact that dreams like Jackââ¬â¢s are common suggests that college is a stressful situation for young people. The cause of this stress can be academic, financial, and personal. Academic stress is common for college students. For many students, going to college is more than just attending classes and taking notes. They usually have a hard time understanding school guidelines and deciding what major they want to study. It is very stressful to read and understand all the school policies, especially the transfer instructions. It is even harder for student to make up their mind what major they should concentrate on. Choosing the right courses and making a schedule is another headache job that students have to go through. Students often find it very tough to decide what are the right classes to take that related to their major. It is also stressful to wake up in the morning and be one time for classes. Finally, preparing and taking mid-term and final exams are the most stressful time that student encounter for the entire semester. In a similar case to Jack, my friend, Som, who is a good student at City College, always gets nervous and stays up all night to study for his mid-term and final exams. Since, school requires students to maintain their GPA to a certain point in order for them to stay in school, passing the classes and getting good grades are one of the most concerning issues for a lot of students. In addition to academic stress, students often feel financial pressure. Most of the college students work part-time while attending college. They have more responsibilities than just maintaining their GPA. Paying for their school tuition and textbooks are the big two unavoidable expenses that they have to spend. Students often complain and feel frustrated about how much they have to pay for their textbooks and other materials related to their classes. Besides these expenses, students also have other financial responsibilities as well. Paying the rent, car payments and car insurance are stressful issues that students have to deal with. Like many other college students and myself, my girlfriend has to work two part-time jobs in order for her to have enough money to pay her bills. Buying clothes, movie tickets, gifts for friendsââ¬â¢ birthdays are other pressures that students have to cop with while they are in school. Base on these expenses, it is pretty obvious that students must have some sort of incomes that they can rely on for the expeneses so that they can service in school and accomplish their dreams. Along with academic and financial worries, students also face personal pressures. For those who have a boyfriend or a girlfriend, they have to deal with their partnerââ¬â¢s attitude and differences. For example, I have a friend who had a boyfriend when she was in college. She had to give up her time to go to a party with her boyfriend in stead of finishing up her assigments. She had to put up with his immature and jealous attitude who wanted her to tell him wherever she went. It was a personal stress for her that she had to put up with her boyfriend while receiving so much pressure from school. Getting along with their family members is a stressful thing to deal with if they live at home with their parents. For some they get homesick and miss their family members if they live far away from home. Another stressful thing for students is achieving their goals. They usually encounter pressure from their parents or relatives when asked when they are going to complete school. They are not sure if their achievements will meet their parentââ¬â¢s expectation. They afraid that they might not get a good job and make enough money to support themselves after they finish school. College students often encounter pressures and streeful situations while they are in school. Academic, financial and personal stress are not new to Jack, my girlfriend and my friend as well as many other students. Theyââ¬â¢ve experienced and are experiencing this pressures while they are working hard trying to make their dreams realized.
