Medea Greek Mythology Essay

When Medea decides to take matters in to her own hands, about punishing the people who have done wrong to her, she is accused of wanting not justice—vengeance. Because I am not a native of neither Corinth nor Colchis, I have my own view about her motives. However, I would agree with the Corinthian Women, Medea is seeking vengeance; not justice. Some people might argue that Medea is seeking justice. When in actuality, Medea wants vengeance. The opposition would say justice took place because the Gods allowed Medea the time to perform her various acts. Although these things happened Medea turned to vengeance when she took it upon herself to kill Creon and his daughter Creusa. Even the chorus, the â€Å"ideal spectators†, implies that Creon is a poor king when, after he banishes Medea, the First Corinthian Woman sympathizes, â€Å"I am of Corinth and I say that Corinth is not well ruled. †(1. 214-216). This quote gives us proof that Medea has some sort of reason to seek revenge on Creon. However she lets her hatred exceed its boundaries and allows herself to take the lives of the King of Corinth and its Princess all because they chose Jason over her. In addition, her actions all prove that she wants Jason to do more than pay for hurting her. She wants him to suffer at the fate of her own children. Her revenge was selfish. Medea involved the two things she knew would hurt Jason the most—her own children. According to the First Corinthian Woman, â€Å"It would be better for you, Medea if the earth opened her jaws and took you down into darkness. But one thing you will not do, for you cannot, you will not hurt your own children, though wrath like plague-boils aches, your mind in a fire-haze bites the purple apples of pain. No blood-lapping beast of the field, she-bear nor lioness, nor the lean wolf-bitch, hurts her own tender whelps; nor the yellow-eyed, seythe-beaked, and storm shouldered eagle that tears the lambs has ever made prey of the fruit of her own tree. †(2. 115-126). Keep in mind that the Corinthian Women are the conscious of Corinth. Through this quote the First Corinthian Women has stated that Medea could not harm her own children. She even gives examples of the most dangerous predators that don’t even harm their own young. This is evidence that Medea went beyond the state of justice; but she went well into the state of vengeance. Medea knew what she was doing and quite frankly she could care less about anything other than what she thought of what was seeking revenge on Jason. In conclusion, vengeance was sought by Medea. She went above the fact of teaching Jason a lesson; she even stated she hated Jason more than she loved her children. Answer this question is what Medea has done entertaining or morally instructive?

Ecosystem Structure, Function, and Change Paper Essay - 1

Ecosystem Structure, Function, and Change Paper - Essay Example This area has aquatic plants and macrophytes, then the euphotic zone where less light penetrate is the habitat for fishes, invertebrates and algae. The lake being shallow does not have deep waters where big fishes survive. This lake mostly has plants, algae, small fishes, insects and amphibians. The lake has bottom sediment known as benthic zone and has a surface layer rich in microorganisms. The upper layer of the sediments is active with the benthic organism, insects and small crustaceans. There are abundant forms of larvae, flies and insects along with fish and other predators looming around the shore and water surface. The lake has a flat mucky bottom which offers plenty of rich food supplies to benthic organisms but is less protected as it has fewer amounts of higher plants which inhibits the formation of higher diversity of structural habitat. This lake is not having much of human interference unless on selected days when people come to visit the place .Some days in a week families and young people do visit the area due to its natural beauty. However, it is seen that people do leave lot of garbage on the lake and its shore which has polluted the lake to an extent. There had been debris of plastic bags, cigarettes, cans, bottles, food waste and plastic wastes. So it is obvious that chemicals might have seeped into the soil and water content of the lake. Plastic bags are a huge pollution to aquatic life and they can release all types of chemicals in to the water body and its eco system. As per (Collazo,2012) â€Å"Humans are directly responsible for the decline of population of certain animals in the littoral zone. Humans harvest animals and plants for food, bait, home aquariums, collections, etc.†. This debris like cigarettes, bottles and cans can release chemicals which can again increase the nitrogen and phosphorus content in water that can have adverse effect on the ecosystem.

Media for Marketing and Advertising Essay Example | Topics and Well Written Essays - 2250 words

Media for Marketing and Advertising - Essay Example The report includes a comprehensive SWOT analysis including charts and relevant diagrams. Also, this paper exhaustively examines the target market and their needs as well as any possible stumbling blocks that the company may encounter when dealing with this particular niche. In addition it conclusively discusses the marketing mix that is the product, the place, promotion and the price of the toy in the UK market. Company’s Overview Hangzhou Kebo factory limited was established in the year 2004 with the main aim of developing and producing better quality toys professionally as explained by Hangzhou Kebo Toy Factory INC. Their toys are aimed at promoting creativity in children and have a high education value. Since then the company has spread its wings to countries outside Asia to as far as Europe. As a matter of fact, the company claims to export up to 80% of what they manufacture. Their biggest importers are the United States of America, Australia, Japan, West Europe and Korea where they have managed to attain a significant market share in these particular countries. The company takes pride in the quality as well as creativity of their products not to mention their expanding popularity. Hangzhou Kebo factory limited boasts of producing many major products including; educational toys, plastic toys, wooden toys and promotional gifts. Toys exported from China The graph above shows the value of toys exported from China. ... The products are designed to assist children to learn about different colours and shapes as well as helping them develop their capability for logical thinking and keen observation. Additionally, their toys can help children learn scientific concepts and this helps to develop their creativity, flexibility, self- confidence and intelligence in their early years. Versatile products Not only can their products be used for games, they can also be used as teaching aides. This ensures that their users get to enjoy both sides of the coin without a hassle. This is both convenient and helps to save time. It also ensures that learning is fun and acts as a measure to avert boredom. Brand reputation Their products have reported high sales and have been well received by customers globally. The company has worked with some of the renowned games and toys producers including Wonderland in Thailand and HABA in Germany (Trader China 2011). The company has secured a considerable market share not only in Asia but also in the Middle- East, U. S. and Europe. Weaknesses The company faces a major challenge as it will be introducing a new brand in the market not just a new product (Alibaba.com 2011). Acquiring new customers will most likely prove to be difficult as the target market already has a brand of their choice (Brassington and Petit 2003). Therefore, it will take a lot of advertising and marketing to sway the customers to take up this new brand as the brand of their choice. The product’s characteristics do not differentiate as much from other existing products in the market. As such the company’s products, that is, the toys they manufacture may not be that different from those already in circulation (Trader China 2011). This will result in the company’s loss if

Essays -sas-ETHICS Essay Example | Topics and Well Written Essays - 500 words

Essays -sas-ETHICS - Essay Example As an example, most people think that if you are doing your job, if you are showing up on time, and if you are listening to what your boss says to do, then you are showing a good work ethic. If you are not doing these things, then they say you have a poor work ethic. We can also break the two words down. As an example, work is what most people would know as something we do in order to get paid. It is also something that could be defined as a job, a drudgery, or something that just has to be done whether we like it or not (Miller, n.d.). Work is something that everyone must do at sometime in their life and it can be working for something else or working for themselves. Ethics on the other hand are something that each individual creates for their own lives. Work ethics can be defined as reliability, trustworthiness, a willingness to learn, a willingness to work, and a willingness to work collaboratively when necessary (Miller, n.d.). With this in mind, we can use the example of a child who is doing their first job as a babysitter. When someone hires a babysitter, they are expecting the individual to know how to take care of their child, whether it is an infant or young child.

Project Management Research Paper Example | Topics and Well Written Essays - 1000 words - 1

Project Management - Research Paper Example The process of project risk analysis is a subjective assessment that is based on the probability of failure to realize the set project objectives within the given time framework and resources allocated (Durkovic & Rakovic, 2009). The risk can occur during the inception, development, and finishing or implementation stage of the project. Briargrove must therefore consider performing an in-depth risk analysis in order to unearth the possible challenges that may hinder the success of the information system development, for the placement of necessary measures to ensure that the project is a success (Durkovic & Rakovic, 2009). The information development project involves three types of risks, that is, known risks, known risks with unknown consequences, and known risks. Known risks are well known to the project development team members and have a high probability of occurrence. ... Unclear definition of project goals, as from the start of the project, is likely to hinder the success of the project in the long run (Cox, 2009). There is a possible risk in poor definition of the project size, which is likely to take the project in the wrong direction and interfere with the time limit. The project plan must be clearly defined for clarity and scheduling within the specified time limit. Risks can be either internal or external, with internal risks being dependent on the team members, project nature, and available resources, whereas external risks entail legal or political influence of the project (Cox, 2009). Briargrove development team must be well aware of the current economic trends in budgeting for the project to ensure that the available resources are well allocated and evenly distributed throughout the project life cycle (Cox, 2009). Poor budgeting and resource allocation is fatal to the project in the case where the resources diminish before the project is com pleted, and there is lack of alternative source of money and other resources (Cox, 2009). The development tools to be used in the system development must be well-known to each of the development team members, and hence the selection of the team members must be a representation of diverse experience levels in the information development life cycle, which reduces the chances of project failure (Durkovic & Rakovic, 2009). Briargrove development team members must choose and agree on a suitable size and the complexity of the project for proper uninterrupted development cycle, which eliminates the possibility of time limit expiry that may require an addition of more time and resources (Durkovic & Rakovic, 2009). Briargrove must also identify probable hazards, potentially harmful phenomena or

Works hours and GBA Essay Example | Topics and Well Written Essays - 500 words

Works hours and GBA - Essay Example Additionally, the application of quantitative method ensures that the data collected is valid and reliable, since it entails the collection of primary data from the participants directly, using tools such as interviews and questionnaires. Through the application of a quantitative method of study, any subjectivity is eliminated, as the findings, recommendations and the conclusions are based on the data collected, evaluated and analyzed. This further serves to increase on the validity, accuracy and reliability of such results and information, as generated by the method. A great advantage associated with quantitative method of study is the fact that the researcher does not have to prepare strictly a design in advance, as the method unfolds in a more natural manner, making it easy for use by even individuals who have no prior experience in research (Alex, 61). The choice of the topic is based on the notion held by many people that if a student engages in work while still studying, it is likely to negatively affect his academic performance, since work is tiresome and exhaustive. While this could be one perspective, there could be many other advantages associated with students involving in work, while still undertaking their studies. For example, it can be easily observed that work provides a student with an alternative channel to break the monotony of class work, through an indulgence in different activities that are not of an academic nature. Therefore, this topic is a vital area of study, in that, the findings of the study will go a long way in making it well understood as to what is the relationship between work hours and GPA among graduate students. Further, the conclusion and recommendations reached by the study will serve to enlighten the academic fraternity on the advantages of students working while still studying. This way, it wil l help students make

Why do Juveniles Runaway Essay Example | Topics and Well Written Essays - 4750 words

Why do Juveniles Runaway - Essay Example Juveniles are the persons not so old; simply they are the minor person included in crimes. The reason for their runway might be different but mainly these are due to lack of attention, abused, abandoned and most of all they are neglected by the family. Some authors stated the cause of runaway is integration problems holding many factor. The runaway of such youth causes great affect on the social and national environment. The family of such youth specially faces mantel torture, rude behavior and tough life a head in their social circle. The causes for such juveniles runaway might be as: Doctor Siegel1 in his books state that usually the youth belongs to broken family involve themselves in such act. The philosophers usually includes in the review that such youth are neglected and thus lack ethics, norms and values that can help in making their life successful. The reason for lacking in ethics is the attention they need while their grooming. The parents remain no more with each other and this cause more on their babies. The youth belongs to broken family fails to get enough training from their elders. Some time it is noticed that though they hold norms but usually these activities are taken by these youth in order to show their elders that they want attention. Have you ever noticed small child behaving differently in front of his/her parents You must noticed that the child want that every one should notice him/her. The same is the reason for such youth. Such teenagers use to behave differently in order to get enough attention, what they really want. Doctor Robert L. Buckwalter2 wrote that usually the community of such young child didn't hold nice friends and locality, simply the term is "peer pressure". The eastern countries usually hold such problems. In South East Asian countries the under ground crimes has many helpers, these are trying to spreading such crimes in the country, the only reason is to make the economy weak. These social circle matters a lot. When the youth use to move with such negative conduct people this causes great affect on the youth. Usually this may be due to the college or university gang. Such gangs attract many youth and trying to produce violence. Therefore, the legal issues of the university and of other community must be so strong that it should help in controlling such violence. Within other causes, the drug use is the major reason of this crime. The drug makes the person unconscious and causes many problems. Have you ever noticed many youth gangs producing violence at world cup game of football The only reason is that these youth gangs are drugged. Due to this the person becomes unconscious and become aggressive if the outcomes didn't come according to him/her. They are drugged due to many reason, either they took it as adventurous or get in habit due to bad community. Whatever the reason is, the drug is the major cause of juvenile's runaway especially in the western countries where most of the youth drugged due to their habit or took it mostly as an adventurous hobby. Juvenile's runaway is

The literary of Philip Sidney Research Paper Example | Topics and Well Written Essays - 750 words

The literary of Philip Sidney - Research Paper Example He was also able to get a university education: something that was only available to a few individual of his time and this inspired his appreciation of literary work. His work was not restricted to writing alone. Sidney was a very ambitious man and sought to have an impact in the political arena that often got him in trouble with the queen. For instance, he protested openly against the marriage of between a catholic duke and Queen Elizabeth (Duncan-Jones, 21). This led to him being banished from Queen Elizabeth’s Court. He now retired to his family estate at Wilton. Politics was the main theme in the Lady of May. It was written in 1578, while Queen Elizabeth was in a dilemma of accepting or refusing the marriage proposal of the Duke of Alencon. She was invited by the Earl of Leicester to his mansion, the Queen accepted the invitation, and stayed several days at the luxurious mansion where Sir Philip Sidney then presented and performed the play, The Lady of May was written for the occasion and for the entertainment of the queen. This writing might be called persuasive and political, because it was designed to win the favor of the queen and to influence political affairs. The Lady of May indicates the literary tradition of pastoral style of writing. Pastoral is a literary style or type of writing that shows the conventional image of rural life. Pastoral literatures are written from the point of view of rural characters, especially of shepherds. In some way, concerns in pastoral works are the tensions between nature and art, and the actual and the mythical. English Renaissance pastoral has traditional roots, nevertheless, it contains distinctly contemporary English foundations, including humanism, sentimentality, depictions of court reality, an anxiety of with real life and the use of sardonic and comedy. One cannot ignore the influence that her mother had on Sidney literary work. This

Post Civil War South Essay Example for Free

Post Civil War South Essay After the war, the South was devastated and it was going to take a lot of money and a lot of rebuilding for it to be self-sufficient again. It financially and architecturally succeeded in reinventing itself and in the thirty five years following the war, Southern iron, steel and textile industries emerged, with Railroads leading the South’s industrial expansion. The Southern economy grew and prospered, although it could never quite compete with the North in innovations or wages. Now that there were almost 4 million freed slaves living in the South and a huge population of poor white people, there was plenty of cheap labor and business owners took full advantage of the fact. What kept the South from a strong Industrial development was the inability of the White men to work alongside the freed slaves. Attitudes toward the freed slaves had not changed and were getting progressively worse. Black Southerners were barred from working in industrial jobs and only a small percentage of White Southerners were employed in these jobs, therefore expansion could not take place. The South started on the right course and for a period of time it looked like the New South had risen but hatred towards the Black Southerners was the industrial development downfall with The South still strongly depending on agriculture as the economy stabilizer. Supposedly, the New South was based on rich natural resources, economic opportunity and increased racial equality, but after the North removed military control in the South in 1877, the Southern White Democrats went to work at changing their states constitutions and establishing legal barriers that kept the Black Southerners from voting. By 1913 new laws had been enacted, known as the Jim Crow laws, the made it unlawful for Black Southerners to comingle with White Southerners everywhere. Violence and Intimidation was the face of the New South now as Black Southerners and White Southerners competed for the same jobs. Lynching’s, beatings, false imprisonment and raping of the Black Southern women was all the freed slaves had to look forward to now, some of the same treatment many had to endure as slaves. Racial Segregation was fully embraced by the White Southerners and lthough the slaves had been freed, the South had completely failed in their quest for racial equality being a sign of the New South. http://www. civilwaracademy. com/reconstruction. html How did the culture of the Plains Indians, specifically the Lakota Sioux, change in the late 19th century? The Lakota Tribe first acquired horses in the 1700’s and it changed their way of life as they knew it. Over the next 200 years, they saw even more significant changes, but none of them good. Their original warfare between other tribes was never to acquire lands or control people but to obtain more horses, as the Lakota directly equated honor with the number of horses they had. Their warfare strategy changed as the white man encroached on their territory, threatened their buffalo and pushed them out of their lands. To them, their way of life was changing and the attitude became that of â€Å"kill or â€Å"be killed†, protecting family and possessions at any cost. Buffalo was a major source of food, shelter and material items that the Lakota relied heavily on to sustain them. As the White man encroached on the Lakota Territory, they felt that if they eradicated the Buffalo, the Lakota Tribe would be easier to manage and beat down. With the Government policy in the mid 1860’s being that of confining all Indians to reservations, the Establishment of the Great Sioux Reservation through the 1868 Fort Laramie Treaty was proposed. This would drastically change their way of life and make them dependent upon the government to survive. The treaty proposed the following: * Set aside a 25 million acre tract of land for the Lakota and Dakota encompassing all the land in South Dakota west of the Missouri River, to be known as the Great Sioux Reservation; * Permit the Dakota and Lakota to hunt in areas of Nebraska, Wyoming, Montana, and North Dakota until the buffalo were gone; * Provide for an agency, grist mill, and schools to be located on the Great Sioux Reservation; * Provide for land allotments to be made to individual Indians; and provide clothing, blankets, and rations of food to be distributed to all Dakotas and Lakota’s living within the bounds of the Great Sioux Reservation. The majority of the Lakota males did not sign this treaty and since the government did not keep their end of the bargain and broke treaty many times as it suited them, numerous battles were fought while they tried to keep their independence. Eventually the Lakota tried to live on the reservation and by the government’s guidelines, but without horses or guns, they could not hunt and the rations promised to them were either always late or didn’t show up at all. The Lakota were encouraged towards self-sufficiency by imposed farming, and the government did everything it could to â€Å"civilize† the Tribe by making them dress in American traditional clothing and outlawing their rituals and ceremonies.

Nanoparticles Obtained by Using Different Gelation Solution

Nanoparticles Obtained by Using Different Gelation Solution 3. RESULTS AND DISCUSSION 3.1 Size of nanoparticles obtained by using different gelation solution 3.1.1 Size of different alginate-based nanoparticles at fixed enzyme and Polyoxyethylene sorbitan mono-oleate (surfactant) concentration Various alginate based nanoparticles were prepared by using different gelling solutions as given in method . The size of nanoparticles determined by DLS is given in table-1. Table-1: Showing size and intensity of nanoparticles at single concentration of surfactant used and enzyme immobilized S. No. Surfactant Conc. (mM) Enzyme Conc. (mg/mL) Cross-linking agent Peak size, diameter (nm) [Day 0] Intensity (%) Peak size, diameter (nm) [Day 3] Intensity (%) 1. 8.203 2.5 BaCl2 89.437 90.6 97.83 74.4 2. CaCl2 87.883 94.3 161.6 54 3. SrCl2 69.193 75.2 91.38 62 4. NiCl2 421.833 100 537.6 75.5 Size was measured on the same day as the preparation of alginate based nanoparticles and there was uniformity in size distribution of the peak diameter which is shown in figures-1, 2, 3 and 4. Figure 1: Size distribution of Ba-alginate nanoparticles: A) on same day and B) after three days. Figure 2: Size distribution of Ca-alginate nanoparticles: A) on same day and B) after three days. Figure 3: Size distribution of Sr-alginate nanoparticles: A) on same day and B) after three days. Figure 4: Size distribution of Ni-alginate nanoparticles: A) on same day and B) after three days. It could be seen that when size was determined on the same day (Day 0), uniformity was observed in the peak diameter. However, when size was determined after 3 days from the development of nanoparticles, the size was found to increase and the distribution was random. This happens due to Oswald ripening. 3.1.2 Size of different alginate based nanoparticles at varying surfactant concentration Different alginate based nanoparticles were developed without enzyme immobilization at different concentrations of surfactant ranging from below critical micelle concentration value to its double as given in Method . The size of nanoparticles is depicted in table-2. Table-2: Showing size and intensity of nanoparticles at different concentrations of surfactant used (no enzyme immobilized) S. No. Surfactant Concentration (mM) Cross-linking agent Peak size, diameter (nm) [Day 0] Intensity (%) 1. 0.006 BaCl2 CaCl2 SrCl2 NiCl2 104.5 70.01 165.9 135 53.7 57.9 61 79.5 2. 0.012 BaCl2 CaCl2 SrCl2 NiCl2 384.5 150 463.7 193.5 94.3 100 100 100 3. 0.024 BaCl2 CaCl2 SrCl2 NiCl2 339.2 71.03 49.65 127.5 52.8 50.9 69.3 62.8 It has been observed from the table that as the concentration of surfactant increases, the size and shape become more regular. Below the critical micelle concentration of the surfactant, uneven and irregular shaped particles were formed. This observation is validated by the size determination of the nanoparticles using dynamic light scattering at different concentrations of the surfactant as shown in figures 5, 6, 7 and 8.

E) Plot for the variation of peak size against changing enzyme concentration. From the various figures of nanoparticles, it could be seen that the average peak size of nanoparticles increase with increasing concentration of enzyme for Barium, Calcium and Strontium. However, in case of Nickel, the size is maximum at 2.5mg/mL concentration of enzyme and it decreases for higher concentrations of enzyme. 3.1.4 Size of different alginate-based nanoparticles at different pH for fixed enzyme and surfactant concentrations Nanoparticles of different sizes and forms were prepared by varying the pH of the buffer solution as described in Method. The peak size diameter of the nanoparticles synthesized is given in table-4. Table-4: Showing size and intensity of nanoparticles at different pH of buffer for enzyme immobilized in alginate matrix against a constant surfactant concentration S. No. Surfactant Conc.

D) Plot shows the variation of peak size against changing pH. From figures 13 and 14, it can be clearly seen that size of the nanoparticles is the smallest at pH 7 and largest at pH 10 for BaCl2 and CaCl2. In case of figure 15, size is smallest at pH 7 but largest at pH 5.36 for SrCl2. However, in case of figure 16, size increases in ascending order from pH 5.36 to pH 10 for NiCl2. 3.2 Determination of membrane structure of the nanoparticles using infrared spectroscopy The characteristic bands for different regions of sodium alginate and its overlay with the nanoparticles developed through Method using BaCl2, CaCl2, NiCl2 and SrCl2 solutions as cross-linking agents are shown in figure 17. Figure 17: FT-IR results of alginate nanoparticles showing intensity bands From figure 17, it is clear that all peaks have shifted downfield. This results in stretching of the bonds between various functional groups and so bond length of increases. Spectroscopic analyses of the alginate-based nanoparticles were based on three distinctive regions of intensity and frequency. The spectroscopic peaks obtained from the graph and their relative assignment to various regions or vibrations or stretching are given in table-5.

Coupling of ÃŽ ½ (C – O) + ÃŽ ½ (C – C) + ÃŽ ´ (C – O – H) vibrations give the carbohydrate region. The mean peak for Barium and Calcium was observed at 1072 cm-1 while for strontium it was observed at 1094cm-1. The overall FT-IR spectra of the different alginate-based nanoparticles are shown in figure 18.The protein region is present between 1700-1480 with bands centered near 1640 cm-1. Asymmetric stretching bands of carboxylate group (ÃŽ ½a COO) were observed near 1600 cm-1 for the various nanoparticles and symmetric stretching band of carboxylate group were centered near 1462 cm-1. In infrared spectra the methylene groups show asymmetric stretching (ÃŽ ½a CH2) near 2922 cm-1 and symmetric stretching (ÃŽ ½sCH2) near 2852 cm-1. OH and NH stretching (3000-3600 cm-1) with peaks at 3436 cm-1 (for Ba), 3434 cm-1 (for Ca), 3442 cm-1 (for Sr) and 3430 cm-1 (for Ni). N.B. Results of FT-IR spectra of D-series nanoparticles are awaited.

So SEM studies are undertaken to have accuracy in size measurement. Figure 21: SEM picture of A) Ba-alginate nanoparticles B) Ca-alginate nanoparticles C) Sr-alginate nanoparticles and D) Ni-alginate nanoparticles (same scale for all images). For SEM-imaging of alginate based nanoparticles prepared using various geling conditions, the samples were gold coated as described in Method. Average size of barium-alginate nanoparticles was 86.8 nm (diameter) and the shape of the beads formed after enzyme encapsulation were spherical. Spherical shaped beads were also formed in case of calcium-alginate nanoparticles with average size of 51.4 nm (diameter). Strontium-alginate nanoparticles also had spherical shaped bead formation with average diameter of 45.3 nm. In case of nickel-alginate nanoparticles, the majority of the particles were rod-shaped with average height of the rods being 310.8 nm. Also, some minor beads were formed having spherical shape and average diameter of 102.3 nm. 3.4 Measurement of UV-visible spectra The UV-visible spectral determination of absorbance of the alginate based nanoparticles was determined within 200-400nm baseline range. Figure 22: UV-visible spectra of Ba-alginate nanoparticles A) At CMC (w/o enzyme) B) At double CMC (w/o enzyme) C) At 1mg/mL enzyme concentration D) At 2.5mg/mL enzyme concentration E) At 5mg/mL enzyme concentration and F) At 7.5mg/mL enzyme concentration. Figure 22: UV-visible spectra of Ca-alginate nanoparticles A) At CMC (w/o enzyme) B) At double CMC (w/o enzyme) C) At 1mg/mL enzyme concentration D) At 2.5mg/mL enzyme concentration E) At 5mg/mL enzyme concentration and F) At 7.5mg/mL enzyme concentration. Figure 23: UV-visible spectra of Sr-alginate nanoparticles A) At CMC (w/o enzyme) B) At double CMC (w/o enzyme) C) At 1mg/mL enzyme concentration D) At 2.5mg/mL enzyme concentration E) At 5mg/mL enzyme concentration and F) At 7.5mg/mL enzyme concentration. Figure 24: UV-visible spectra of Ni-alginate nanoparticles A) At CMC (w/o enzyme) B) At double CMC (w/o enzyme) C) At 1mg/mL enzyme concentration D) At 2.5mg/mL enzyme concentration E) At 5mg/mL enzyme concentration and F) At 7.5mg/mL enzyme concentration. From the spectral figures 21, 22, 23 and 24 it can be clearly seen that the ÃŽ »MAX for the different alginate-nanoparticles is around 235nm. It can also be clearly seen that the protein content at 280nm increases with increase in the concentration of enzyme immobilized in the alginate matrix. The spectra of the alginate nanoparticles show peaks and stretching only within the UV range of 200-330 nm of the spectra and then the absorbance becomes constant. The nanoparticles which were made without the immobilization of enzyme at CMC and double CMC of Polyoxyethylene sorbitan mono-oleate had the least absorbance at 280 nm in all the different types of nanoparticles depicting the fact that no enzyme was encapsulated within them. 3.4.1 Variation of O.D. with protein content Figure 25: O.D. variation plot against varying protein content at 280nm for A) Ba-alginate nanoparticles B) Ca-alginate nanoparticles C) Sr-alginate nanoparticles and D) Ni-alginate nanoparticles. From figure 24, it can be seen that Nickel-alginate nanoparticles have the highest amount of protein immobilized within the matrix. While, the protein immobilized in Barium, Calcium and Strontium alginate nanoparticles are observed to have the similar amounts of protein immobilized in them. 3.4.2 UV-visible spectra for d-block element-based alginate nanoparticles The overlay of alginate nanoparticles developed from d-block elements is shown in figure 26.

Cold War Essay -- essays research papers

After World War II, Stalin did not remove his troops from Eastern Europe as he pledged he would in the Yalta Agreement. Instead, he setup â€Å"puppet governments† which did exactly as Mother Russia stated. To protect it’s interests for national security, the American Dream, and the belief that all people should have the right to a democratic life, complete with liberty, equality, and a representative government. Also playing a large part in Cold War tensions was the US interest in protecting its profitable foreign markets. The spread of communism challenged every one of these US aim’s, and therefore the US became convinced it had to stop this spread. The deliberate opposition to the spread of communism to capital countries is known as containment, which the US adopted in the late 1940’s. The US believed it must do everything in its power to uphold containment and save it’s peoples way of life. Another theory that soon surfaced that was related to t he containment theory was the domino theory, which stated that as one small country fell to communism, surrounding small countries would also fall to communism rapidly.   Ã‚  Ã‚  Ã‚  Ã‚  In the spirit of containment, strongly supported by President Harry Truman, was the main driving force behind the Korean War. Along with containment as a force was American Pride. After World War II and after Japanese occupation, Soviet troops moved in to North Korea, and the US moved in to South Korea. Each setup and supported its own go...

Changing the World in Milton’s Paradise Lost and Cavendish’s The Blazin

Changing the World in Milton’s Paradise Lost and Cavendish’s The Blazing World It only takes one person or one event to change the course of the world. Eve changes the world and the course of humanity when she eats from the tree of knowledge in John Milton’s Paradise Lost. In Margaret Cavendish’s The Blazing World, the Empress single-handedly changes the world she rules for the worse, and then changes it back again. The message is that our worlds are not fixed; they are ever changing—fickle and subject to one event or action. Humans must realize that the actions of even one person can produce world-altering effects. The film Pleasantville demonstrates this idea. In the film, David, an unpopular and unhappy teenager in a post-lapsarian world, idealizes the life he sees in reruns of a black and white fifties television show called Pleasantville. After a visit from a mysterious television repairman, David and his sister Jennifer are transported into the show and into the lives of the characters Bud and Mary Sue. Jennifer, now known as Mary Sue, hates her new colorless existence, and sets about to change the town of Pleasantville. Her actions and ideas lead to the introduction of passion into Pleasantville, creating a whole new world-view for these naà ¯ve citizens. Mary Sue’s actions, at first scorned by her brother, now known as Bud, soon begin to change him, too. He leaves his unpopular, passionless existence behind, and finds the same pleasure in the discovery of passion as do the Pleasantville citizens. Mary Sue, who once scorned Bud for his love of Pleasantville’s depiction of a worry-free fifties life, now understands the virtues of that life; she begins reading and goes to college. Bud and Mary Sue chan... ...erence in the world, but I have found that even one person not eating meat saves thousands of animals and hundreds of acres of rainforest, and prevents an immeasurable amount of environmental degradation. Besides, according to Milton, Adam and Eve were vegetarians! Milton and Cavendish both give examples of a world being changed by the actions of one person. Interestingly, Adam and Eve’s world and the Empress’s world were perfect before they were changed. Today, our world is far from Eden or Paradise, and we are constantly bombarded with changes—sometimes for the better, sometimes for the worse. Our responsibility, a lesson we can take from Paradise Lost and The Blazing World, is that all of our actions have an effect. We must make sure that the effect is desirable and beneficial to all of humanity, and remember that it just takes one to make the change.

Child Shift

The article entitled â€Å"Children Caught in the Crossfire† explores the effects of proper and dysfunctional parenting on Caribbean children. This article identifies dysfunctional homes that foster improper parenting and the impact of psychological and physical absence of parents on their children. It also assesses the consequences of â€Å"child shifting† on affected children. The social impairments of children suffering from â€Å"child shifting† were cross-examined with the various parenting styles they would receive through continuous domestic relocation. Children Caught in the Crossfire† is an interesting article that exploits numerous factors involving parental negligence which causes child shifting. This has become a cliched situation in the Jamaican society as a vast percentage of Jamaican parents have become surprisingly negligent. Whether by improper parenting or defaulted situations, children have suffered from these mal-outcomes and this has become evident through child development assessments explored within the article. This matter of unnecessary mobilitychild shifting is of personal and public interest which has become the drive upon which the research will be carried out. As a tertiary level student that lives and has been cultured within the assessed environment (Jamaican society), my interest has been stimulated to assess the factors surrounding the nature of this negative lifestyle pattern. This article has highlighted my sensitivity to this situation due to personal reflections (to some extent); analytical efforts will be made to completely understand this critical matter that decreases national productivity and development. Conclusively, after assessment of the article putting concepts into proper perspective, the research topic and question is as follows respectively: The impacts of child shifting on the psycho-social development of Jamaican children and what are the effects of child shifting on the psycho-social development of Jamaican children in changing family structures? The subsidiary questions are: what is child shifting and how does it affect child development, what are the causes of child shifting and will victimized children transit consequent behavior into adulthood, what are the social and psychological factors that affect child development and what are the long term implications of child shifting on the social and psychological development of Jamaican children? Tentative Thesis Child shifting strongly impairs the psycho-social development of Jamaican children which causes their inability to function normally during daily social and psychological situations. Relocation of children after divorce and children’s best interests: New evidence and legal considerations. 17 (2), 206-219. Arizona State University & University of California. The article assesses the effects of child relocation after divorces through a persisting legal issue. The article incorporates statistical date with the views of Wallerstein and other theorists that assess the best interests of a relocated child. This legal issue assesses which caregiver would have the least negative effects on child development. This article is a follow-up on another article explored during the research. This article supports the research through the additional clarity gained from a second assessment of Wallerstein’s theory. The article highlights positive and negative aspects of child relocation. This adds to the research’s objectivity bringing about views that support and oppose the researcher’s stance. Jackson, T. (1957). The differential impact of family disorganization. In Johnston, N. , Savitz, L. , Wolfgang, M. E. (Eds. ). (1962), The sociology of crime and delinquency (pp. 331-338). New York & London: John Wiley and Sons, Inc. This chapter assesses the occurrences of delinquency in children from broken homes. These broken homes were not stated as causes of juvenile delinquents though aspects of disorganized families contribute to the development of delinquency and personality problems. The article states that more critical factors affect delinquency as family disorganization complicates the issue. This article directly contrasts the researcher’s views as disorganized families is directly associated with delinquency. Family disorganization via broken homes is the most common cause of child shifting. This broken home fosters child shifting and the negative psycho-social development of the child which commonly causes juvenile delinquency in the Jamaican society. Pasahow, R. (2005). A critical analysis of the first empirical research study on child relocation, Journal of Critical Analysis of Relocation Study, 19, 321-328. This journal assesses Wallerstein’s study of the best interests of children and the effects of child relocation. However, Wallerstein is opposed by several theorists with supportive research findings. Wallerstein posits that child relocation with their custodial parents is in their best interest while opposing views disprove Wallerstein. The scholarly article explores opposing views of several theorists which gives the researcher an understanding of contrasting arguments on child relocation. The source outlines the effects of child relocation in child development depending on custody. This aids the research in finding out the effects of custodial and non-custodial parents on child development. Samms-Vaughn, M. (2005). Children caught in the crossfire. In Ramsay, P. (2009). Blooming with the pouis. Ian Randle Publishers. This article outlines functional and dysfunctional parenting of children in Caribbean homes. It further assesses the effects of child shifting in various domestic settings. These varying domestic settings included dysfunctional homes which are known to be a cause of impaired psycho-social development. This article supports the research as it sets the basis on which the research is done. The article connects child shifting to the dysfunctional homes that typically cause child shifting. This article also states the effects and what would typically happen in later years.

The Geert Hofstede Cultural Dimension Business Essay Essay

This chapter is divided into two sections. The first section defines culture, its importance in international business and the various cultural dimensions for working globally. The next section describes the culture of India and U.K. and reviews the impact of culture on the working of Hilton Hotel Group in both the countries. Finally, it ends with a brief summary. CULTURE Hofstede (2003) defines culture as â€Å"the collective programming of mind that distinguishes the members of one human group from another.† It is evident that people from diverse environment can misunderstand each other. When two people interact in an organization, culture characterizes their behavior and attitude towards others. When a company plans to start a business in abroad, employees with good communication skills and with the ability to adapt into new environment are chosen to travel and interact with people of various cultures and nationalities. (Mead, 1992) This table shows the division of world’s population according to Region, Language and Religion which are the major aspects of determining ones culture. Taylor (1870) defines culture as â€Å"that complex whole which includes knowledge, belief, art, morals, law, customs, and other capabilities acquired by man as a member of society†. Culture plays a very important role in business. All civilizations have its own cultural elements like language, religion, values, attitude, customs, education, aesthetics and social institutions. (Czinkota, 2007) Culture passes from one generation to the other, however it can vary from one group to the other. Every society has its own point of view and opinion about various situations; however, it acts as a barrier to communication. (Daniels, Lee and Sullivan, 2004) CULTURAL DIMENSIONS Geert Hofstede, a much known professor carried out the study of impact of culture on individuals at a workplace. It took him six years to complete this study as it consists of interviews of more than 100,000 employees from 70 countries. According to Hofstede 2004, â€Å"the UK has 35 points in power distance, 89 in individualism, 66in masculinity, 35 in uncertainty avoidance and 25 in long term orientation†. Power Distance – According to Hofstede, 2004, â€Å"Inequality exists in every culture; however the extent to which less  powerful members of the society agree to the inequality differs from one culture to the other. Power distance is related to the different solutions to the basic problem of human inequality† High power creates less communication amongst the bosses and employees whereas when the power is low, employees communicate more with their superiors for the decision making purposes. Individualism vs. collectivism- Individualism is defines as the cap ability of a human being to only take care of himself or his family where as collectivism describes a group of people who look after each and every member of that group. (Hofstede, 2004) These two dimensions describe the individualist or collectivist culture of a human being. Masculinity vs. Femininity – The third dimension is one of the most dominating factors of a culture. Countries where men are considered to be more strong and tough and women are considered to be more delicate and soft follow masculine culture where as countries where men and women are considered equal in terms of strength and tenderness follow feminine culture. (Hofstede, 2004) Uncertainty Avoidance – It is the level to which an individual can accept sudden changes and situations. Companies which have the tendency to admit unpredicted circumstances and dislike uncertainty have high uncertainty avoidance score culture whereas countries which take things as they come and are prepared for any change at any point of time have low uncertainty avoidance score culture. (Hofstede, 2004) Long term vs. short term orientation – The fifth dimension known as the Long term vs. short term orientation was discovered quite later by Hofstede with the help of a survey intended by Chinese scholars. According to Hofstede (2004), â€Å"long-term orientation means focusing to the future whereas short term orientation is focusing on the present and past. In long term oriented societies, pragmatism, perseverance is valued more; in short term oriented societies, respect for tradition and return favours is valued more†. HOME CULTURE VERSUS FOREIGN CULTURE Tayeb (1998) says that the decision to become involved in international business depends, among others, on the size of the company’s domestic market, its production capacity and capability, and the financial and other resources that the foreign market requires. In that way, firms can be placed on an internationalisation scale ranging from domestic single nation to  totally globalise. The extent to which national culture becomes relevant to a firm can be shown in the following table. The company’ own home country culture is of high relevance, though the managers and other employees may not be aware of its influence. The relevance of other people’s culture becomes greater for a firm as it spreads its activities and products past its national boundaries to reach foreigners with different value systems and tastes (Tayeb 1998). IMPORTANCE OF CULTURE IN INTERNATIONAL BUSINESS Understanding culture and its impact on international business is very important for the firm and its employees. Organizations differ not only on the basis of international culture but national culture as well. According to Ball et al. (1996), doing business with another culture is not an easy task and to be successful, every foreign company should be aware and follow some rules that make their business activity more compatible. They state that there are six rules of thumb for doing business in another culture. Even if these can be important when doing business in the home country, they become more crucial when going abroad. Johansson (2000) states that it should be kept in mind that even if adaptation to the foreign culture is good when it comes to future negotiations and co-operations, there is a limit for how far a manager should go to try to accommodate this foreign culture. Mistrust from the other part can be created if for example a manager is trying to adapt to the foreign cul ture and is doing this superficial and with lack of deeper meaning. This can lead to misinterpretation and seen as matter of insincerity. When a company begins to work outside its national country, it encounters various environmental and cultural changes which is not the case in own country. If one does not understand these cultural differences, then he might to face barriers in the success of the organization globally. (Lane et al, 2001). More international operations lead to more interaction and communication with people and companies working in different culture. Therefore, in order to operate productively, it is a basic need to understand or have knowledge of different cultural attributes and contrast. (Adler 1983). Ferner and Quintanilla (1998), state that â€Å"companies need to operate as one organisation which face global environment although they are consisted of different subunits which carry the characteristics of the local environment  they operate in and the companies also bring the cultural elements of the home countries which they o riginated in† Since the study of national and international cultures has become of the most acknowledged topic, therefore, it is important to learn culture, its importance and impacts in international business. IMPACT OF CULTURE ON INTERNATIONAL BUSINESS According to the article on Cultural impact on international Business, 2011, Culture influences international business in many ways. When culture and business interrelate with each other, it directs to the growth of fascinating circumstances or situation. When diverse cultures come together at an ordinary point with business as the podium, the spar is bound to happen. But most significantly, such circumstances assist us in becoming accustomed to demanding situations. Various societies or nations around the globe pursue different gestures and manners. The technique to see a difficulty might vary from country to country in the world. The global business culture, altogether, is an assembly of a variety of industry tradition, cultural power and the consideration development followed in different countries. Below are discussed the impacts of culture on an international business on the basis of body language, communication, time etc. Body Language Every country follows a different culture, which can be clearly found or seen in the behaviour and body language of its people. In order to work internationally, accepting the facts about underneath gesture or motion becomes essential. There is likelihood that people can get the wrong impression about the actions of different cultures. Thus, it calls for an accomplished planner to handle tricky state of affairs for the duration of conference. (Moran et al,2011) Communication Communication is another aspect of culture that affects the international business. Different countries have different ways of communication. The words and vocabulary used by a few people might sound unkind to others. The pronunciation of some words could have a different impact on the cultural ways of communicating in the commercial sector. This can also act as an obstacle in the progression of business communication. (Moran et al, 2011) Time The first thing that comes to mind when we talk about time in business in Punctuality. Britishers and Germans are very punctual and follow a time-bound schedule. The various ‘time-cultures’ could be one of the major factors for creating differences amongst people from miscellaneous ethnicity. Multinational Companies follow a schedule for meetings while doing a business and the way in which meetings are handles could also be the cause of having different point of views. (Moran et al, 2011) â€Å"It is necessary for corporate houses to understand the social conditions of different countries, to successfully tap the respective markets. Being sensitive to the values and beliefs of different cultures of the world is necessary†. (Leung 2005) The marketing executives sent abroad to operate business out of the country go through various problems and difficulties in trading with the commercial tradition and customs of that country. To target the international market and customers is not an easy task. It requires qualified experts who are trained and talented to deliver the best of their capability to the clients. CULTURE OF INDIA India is a vast country which houses diverse cultures, ethnic groups and races. The immense population of more than a billion people has resulted from invasions, relocations and inter-marriages that took place over the centuries. According to an article published in the Inter science Management Review (2012), the various customs and traditions followed by people reflects in the business mores of India. With the advent of technology, the companies have now started to venture out into international markets. It has thus helped the human resources and the organizations to get exposed to diverse working environments across nations. India has greatly benefited by this turn of events as the gap in the work culture of India and other nations has thus decreased to some extent. INDIAN WORK CULTURE First and foremost, the Indian etiquette calls for Namaste being a fundamental mode of greeting or saying goodbye. Recently though, education has brought about a reform in this practice as men and women now prefer to shake hands. Due to their politeness and respect towards their guests,  Indian people have trouble saying no. This aspect of their nature may act as a hurdle in sealing of contracts or doing negotiations. Paramount respect, courtesy and generosity is showered upon guests in India. It is a utopia for the international travellers. (Rai and Neelankavil, 2009) Rai and Neelankavil, 2009 also state that one of the major drawbacks of the Indian work culture is that there is no management of time. Indians don’t score too well in terms of punctuality; long delays in meetings, cancellation or rescheduling of the same are a common sight. This has found its roots in the basic mindset of people and the Indian culture. Another major failing of the Indian work system is the general slack of work in the Government offices which leads to delays in meting out results, excess of the red tape baggage that leads people not to have confidence in the system. Therefore, any transactions in India call for a huge amount of patience to be able to meet with the results. The article published in Inter Science Management Review, 2012 also states that Despite other shortcomings, Indians fare well in matters of the English language. The adeptness of the average middle class over the language is laudable. There is absolutely no hitch in sending and receiving of official letters, emails or faxes. The office environment in India is usually very formal and there are no personal relationship between the bosses and the subordinates. The decision making in almost all of the private companies is from top to bottom, which may take a long time for the decision to be made and implemented. This accounts for the general lack of management inside the working sector. Most of the Indians carry their work pressure home. They put in extra hours at work hence losing the work-life balance. This creates more pressure on them as the workplace demands are entirely different from that of the family. All this is done in an effort to earn monetary benefits and climb higher on the ladder of hierarchy of the workplace. Indians generally don’t make good mentors, they are soft critics and don’t stand up against something wrong as much as they should. This is thought to be because of the process of appraisal, the appraiser demands positive feedback despite the gaping holes in management and work. The lack of dexterity of the appraiser is usually the main reason behind lack of the much needed critical review. Indians have a hard time coping with changes of any sort, be it changes in management or work timings. A lot of time and energy is required for Indians to bring the change to practice. IMPACT OF  CULTURE ON HILTON HOTEL, INDIA One such new path is the concern with national culture. Whereas traditional IB research has been concerned with economic/legal issues and organizational forms and structures, the importance of national culture – broadly defined as values, beliefs, norms, and behavioural patterns of a national group – has become increasingly important in the last two decades, largely as a result of the classic work of Hofstede (1980). National culture has been shown to impact on major business activities, from capital structure to group performance Gibson (2002). Cross-cultural experimental literature examining the influence of individual characteristics has evolved, yielding greater sophistication and specification to our understanding of culture’s influence. Much early cross-cultural work tested only for the main effects of culture – often using national culture as a proxy variable for a given cultural orientation. That work, exploring the influence of the presence (a main effect) of a given cultural orientation, laid the groundwork for more complex experiments to follow, which test how differences in the levels (a moderating influence) of a cultural orientation (even a primed, temporary one) influence behaviours or perceptions. The research of Gelfand et al. (2002) examined both the main effects and the moderating effects of individual characteristics on the Hilton Hotel in India. Using national culture as proxy for cultural orientation, their results support robust findings of self-serving biases in individualist cultures (Thompson and Lowenstein, 1992), where ‘the self is served by enhancing one’s positive attributes to stand out and be better than others’, but find relatively less bias in a collectivistic culture, in which ‘the self is served by focusing on one’s weaknesses to blend in and maintain interdependence with others’. However, they also measured individual self-construal, and demonstrate that independent self-construal are higher in India and are positively related to self-serving biases. Thus, not only is a main effect of culture on the working of Hilton Hotel in India, but the examination of individual self-construal helps to explain why such an effect exists. Research of this type is especially valuable given that much of the theory underlying business research has been developed and tested exclusively in Western contexts. Diversity: Most organizations in the India, particularly large  ones, strive for consistency, standardization, and agreement, largely from the misleading assumption that the elimination of divergence/diversity automatically results in efficiency and success. This traditional view of organizational structure assumes that contradictions are to be first prioritized, and then eliminated, so that everything will run smoothly. We have all known managers and executives who need their subordinates to agree with their decisions, tell them they are doing a terrific job, and avoid challenging their authority. While this may be organizationally neat and psychologically comforting, it is stifling, stagnating, and, over the long haul, counterproductive. Experimental research focusing on the moderating influence of individual characteristics contributes to this literature because it directly tests whether these processes, biases, and behaviours are indeed universal phenomena, or whether they are specific to Western populations. As Oyserman et al. (2002b) point out in their Meta-analysis of research on collectivism/individualism, cultural priming is one of the most promising areas of cross-cultural research. The theoretical underpinnings of priming stem from social cognition research, which shows that accessible knowledge influences behaviour, and that temporarily accessible and chronically salient knowledge produce equivalent effects in the laboratory. Thus, priming techniques ‘create an experimental analogue of chronic differences between cultural groups by temporarily focusing participants’ attention on different cultural content or values’. (Hong et al., 2000) Examples of this research would be the study mentioned in an earlier section, as well as which primed participants with cues that were or were not congruent with their cultural orientation (e.g., using pronouns such as ‘I’ and ‘me’ for an independence priming or ‘we’ and ‘our’ for an interdependent priming) and examined the influence on factors such as cognitive speed and accuracy, memory, and attitudes. Results across all the experiments indicate the existence of a chronic cultural orientation, and one that is more malleable in the face of a primed orientation. CULTURE OF U.K There are about 3.7 million businesses in the U.K which includes 75% of jobs in service industry like hotels, restaurants, travelling, shopping, computers and finance. This sector consists of more than 20 million  employees and 22 percent of British workers work more than 48 hours a week. (Pryce, 2007) According to the Central Intelligence Agency (2007), the United Kingdom is one of the most developed countries in the world and being a leader in trade as well as the leader as the financial centre. It is seen as one of the largest five economies in Europe, with banking, insurance and other business services being an integral part of it. As the United Kingdom is a part of the EU, most of the institutions and policies are in accordance with the regulations laid out by the EU. As the UK has a monarchical constitution, the government rarely gets involved in the matters of economy, its main concern is with improving public services like education and health (The Economist, 2007). A large number of international and global enterprises find home in the United Kingdom (Ferner and Varul, 2000). Due to diverse work environments provided by these global enterprises, the British companies get to experience the work culture provided by the international markets and manage it efficiently. An argument provided by Ferner and Varul (2000) states that the British enterprises have a niche above other companies in terms of development of customer friendly policies and structures. Also, these enterprises play an integral role in globalization of industries, thus placing UK in the top realm to play the role of international operations armed with international companies. Hence, the UK could be expected to be the place with the most number of globalized companies with leading role of international operations. KEY CONCEPT AND VALUES OF BRITISH CULTURE According to an article on International Business Negotiations 2005, United Kingdom consists of a blend of four cultural and ethnic backgrounds named as England, Scotland, Northern Ireland and Wales. Such a multicultural country persists to bring together its rich culture and modern attitude. The understanding of the basic principled business standards of the United Kingdom is very important for any company that wishes to operate business in such an inherited and reputable country. Indirectness – The most important aspect of British culture is its way of approach and communication. In the U.K, people are known well for their graciousness and good manners like courtesy, politeness and civility. While undertaking business in the UK, it is seen that straight questions obtain indistinct answers and the exchange  of dialogues takes place in detail. In order to understand what one really means to say, it is necessary to take note of the nature of voice and facial expressions. (Whi ttaker, 2009) ‘Stiff upper lip’ – â€Å"The term ‘stiff upper lip’ is often used to describe the traditionally British portrayal of reserve and restraint when faced with difficult situations†. All business meetings and deals are done with entire regulations and customs. Any positive or negative form of emotion should be neglected in the british work environment. (Whittaker, 2009) Humour – A vital element in all aspects of British life and culture is the renowned British sense of humour. The importance of humour in all situations, including business contexts, cannot be overestimated. Humour is frequently used as a defence mechanism, often in the form of self depreciation or irony. It can be highly implicit and in this sense is related to the British indirect communication style. (Whittaker, 2009) The United Kingdom is renowned for its colourful history and strong sense of tradition that has been shaped by a colonial empire, both civil and European war and a constitutional monarchy. The fourth largest trading nation, the UK is fast becoming Europe’s leading business centre. Supported by a long-established system of government and economic stability, the UK is a n attractive base for overseas business, offering skills in areas such as research, development and technology. However, in order to operate successfully in the UK business environment, there are a number of important issues to take into consideration both before and during your time there. (Kenna and Lacy, 1995) IMPACT OF CULTURE ON HILTON HOTEL, U.K. There are quite a few Hilton Hotels in the U.K. The most important cultural factors that affect the business of Hilton Hotel in U.K. are as follows: – PRICING Price plays a key role in creating customer value and building customer relationship, as well is one of the four elements of the marketing mix and an indicator that affects buyer choice. Many companies today compete with each other with different prices in both the domestic and the international market. Price is the only element in the marketing mix that produces revenue; all other elements represent cost (Kotler et al. 2007). Pricing is one of the most complicated decision areas encountered by Hilton Hotel, U.K.  Market prices at the customer level are much more difficult to control in international markets than in domestic market. The pricing of the Hilton Hotels in the U.K. in general is more complex and critical than those located in India. According to Chee et al. (1998), the price is critical because it affects the firm’s ability to stay in the market. The price is also complex, because of the diversity of markets, with their different environment such as, political, l egal, social, technological, consumer characteristics, etc. Thereby, price is an issue that can affect the international business and the company’s co-operations in the foreign country NEGOTIATIONS According to Tayeb (1998) language is one of the major issues when it comes to negotiations with trade partners from other cultures. Although it is not always indispensable to know the partner’s language, several studies shows that a link exists between successful company performance in winning new business in foreign markets, and the ability of the company to conduct its business in the language of the customer. Tayeb (1998) also states that there are some aspects of culture that manifest themselves in a negotiation situation. Foreign partners not only speak languages other than one’s own, but also have a tendency, for cultural reasons, to think in different ways and have different priorities in the way in which they do business. For example, some people prefer to do their business meetings with foreigners in a formal way, and would be offended to be addressed by their first name; some might believe that the use of an informal style and first name would signal to the p artners that they are trusted. Two partners from these different cultural backgrounds could easily misunderstand each other if they negotiate without a previous knowledge of one another’s assumptions and values. SUMMARY In today’s time of globalisation, international business is getting bigger and escalating for both multinational as well as local companies. Due to this, cross cultural matter have gained a lot of importance. In this literature review, the main focus has been to discuss culture, its importance and impact on Hilton Group of Hotel in India and U.K. This chapter has been presented to help the reader understand the basic  theoretical concepts which helps in the findings of the case study and answering the research question. This part of the thesis helped us in understanding the relationship between culture and international business. Development in the fields of technology and communication etc, companies from various cultures have started working together, thus making culture an important subject of discussion in International Business. This chapter discussed the Hofstede’s five cultural dimensions named Individualism, Power distance, Uncertainty, Masculinity and Long-Te rm orientation. It also explains the working culture of India and U.K and the impact of culture on the business of Hilton Hotel, India and Hilton Hotel, U.K. In international business negotiations, it is important to learn about the counterparts‟ culture and thus ameliorate the problems that can arise in the course of the negotiations. From this study, we can see that there are marked differences in the Indian and British negotiation styles which stem from cultural differences among the two countries. Knowledge of these differences will enable negotiators understand the negotiation behaviour of their counterparts with a view to making negotiations proceed with more ease. However, it is also important not to allow cultural stereotypes to determine the relationships with the potential business partners. This is because individuals may have their own distinct culture which does not always mirror the country’s perceived culture.

Digital Telecommunications and Network

A network is defined by Noergaard (2005) as a collection of two or more connected devices that can send or receive data. He further adds that the relationship between these connected devices in a network determines the total architecture. The purpose of this report is to understand the networked applications architectures. Two networking architectures are covered here; the client/server architecture and peer-to-peer architecture. The report first gives an outline of these two architectures and their advantages and disadvantages.It is seen that the industry divides its products on the concept of client-server model or peer-to-peer model. Some applications perform better with the former model while others perform better with the later model (Klemt 2005), 1992). Based on the understanding of this report, two separate scenarios for a basic networking application will be analysed. The idea will be to judge the type of networking architecture to be used for each scenario. Finally based on the entire analysis, a conclusion will be drawn as to which resource has to be used in what situation.Part 1: Review of Client/Server and P2P application architecture Client/Server architecture Client-network computing is one of the most basic paradigms of distributed computing, and this architecture is based on the paradigm as described by Jalote (2005). This architecture has a minimum of three components – a client, a server and a network that connects these two systems. This is a two level architecture where a client requests a service and the server provides it (Singh 2005). The server is usually accessed through a remote procedure called RPC, request of which is defined by their signature.The processing of the request is internal to the server and is transparent to the client. The client and server may be on different or same systems Advantages of client/server architecture Client server architecture using RPCs has been used for over a decade for system wide exchange com puting (Singh 2005). The main reason for this is the high level of reliability this architecture provides. It is also found that the cost of the entire system over a period of time is less than that used by other architectures.In addition, the architecture also enhances safety since any of its components can be removed without a major impact on the other system. This architecture leads to a better distribution of resources through the system. This architecture also leads to increased productivity because the front and back end distribution of processes is optimised (Jalote, 2005). Disadvantages of client/server architecture The main disadvantage of the client/server architecture is that there are multiple databases in the client/server environment, making the management and synchronizing of the data shared between them difficult.This also leads to a difficulty in software distribution and configuration management program, as the system is distributed. The cost of maintenance may als o increase because of the different networks being inter-networked. P2P architecture Peer-to-peer or P2P architecture is another way of managing distributed applications. In this method, the individual nodes have similar and comparable roles, unlike the client/server systems. In this architecture, the nodes are given roles such that both can act as client and server. This type of connection requires at least two computers connected to each other (Reid, 2004).In order to function correctly each node of the system should know the address of at least another node. Each node can directly contact the other node of the system for using its resources, without going trough the server (Heathcote & Langfield, 2004) Advantages of P2P Architecture This type of communication exists since the time of old IBM PCs. The primary advantage of a P2P network is that it is fault tolerant and there is no single location for the fault. This means that the system works well even when several of its componen ts are missing (Verma, 2004).Also the combination of processing power of multiple nodes in a network greatly increases the efficiency of the system in terms of combined processing power and storage when compared with a central server. P2P systems are hence extremely autonomous and can secure anonymity. They can be generally deployed in an ad hoc system without requiring central management or control. Finally, unlike the client/server systems there is no need for a separate network operating system (Reid, 2004). Disadvantages of P2P Architecture The manageability of peer-to-peer systems is much harder, due to the extremely distributed nature of the system.Security is also not centrally controlled and the users need to remember different passwords for accessing the resources located on different nodes on the network (Porter, 2006). Facilities such as backup are the responsibilities of the individual user unlike the client/server systems where the server can schedule them. This system works best for lesser number of systems in a network, usually under 10 (Reid, 2004). Part 2: The architecture of Mr. Robertson’s home network Network Architecture The architecture which I would suggest for Mr. Robertson’s home would be a peer—to-peer network.There is no necessity for a client/server model in this case. Also no type of hub system is required, since the application is very simple Justification As is already explained in the section above, a peer-to peer network is used for ease of applications without extra overload. The system works best for systems which having less than 10 systems. As Mr. Robertson’s system uses only two computers, the system is ideal for this purpose. In addition to this, the home network does not require the additional overhead of a server so a pure peer-to-peer system, one without any server (Subramanian & Goodman, 2005), can be used.The application mainly used is the file sharing which can be easily done. Also for us ing the internet, there is no necessity for the system to have simultaneous connections as is already mentioned in the example. While, to most intents and purposes, a printer application requires the use of a server so as to manage the print request being sent from multiple systems, this is clearly not the case here. The network should merely have the capability to receive print jobs from both the systems a simultaneous operational capability is not really required, as the application would not be too critical.In the worst case, the print job could be cancelled and given again. Finally, the use of a client server system would in addition to setting a server, also need additional components and software like an operating system, which is not required in this case, as there is no need for tasks like allocation resources, backups etc. Also, Mr Robertson gets the advantage of removing any of the two systems from the network at anytime, and the second component would work just as well, a s neither of the system is a server. Components for the home network In addition to the 2 computers and printers purchased by Mr.Robertson, he needs very few components to get his system up an running. He would need the cable modem, a twisted cable pair, media converter for running the internet through cable, a splitter and a print sharer. There is no necessity for a hub for such a system, which is necessary only if there are more than two computers on a network. The splitter would divide the internet connection to the two systems which will the function of the print sharer also. A wireless NIC or a wired one can be used to share the network. Only single numbers of components, except the connecting cables, are needed because there are only two computers.Topology of the home network The figure above shows the basic topology of the network. As explained above, there is no need for a hub for just 2 systems. The printer can be connected either via a print sharer or the software can be u sed to do that by accessing the network. Here, each computer can access the network printer. In addition, the cable connection that comes can be split into two using a splitter. This type of networking requires basic minimum of components and can be used for connecting systems on a home network. This system is extendable to more than two systems.The only difference would be that in that case, a hub would be used between the two systems instead of just a cable. Also the cable type, which is twisted in this case, might be changed for more than two computer systems, because of load factors. In this case also, there will not be any necessity for a server, as the printer tasks will be shared, but not scheduled or managed by an external system. Part 3: The architecture of the LAN of BC Inc. Network Architecture For the company’s LAN, a client server system is a must. There are only 16 systems, on the LAN would more than fulfil the application necessity.There are multiple applicatio ns needed for this system. There is the printer service which is multiple in numbers and locations. In addition, there is the obvious necessity for an email and web server for the business applications. All this necessitates are need for the use of a client/server model. Justification In many of the situations given above the peer-to-peer network fails to have any use. First and foremost is the number of systems. The P2P system is only suitable if the number of systems is less than 10, as mentioned earlier. Also it is not just the number of system that is a problem, since it is not a very huge network.Office applications as a rule need more features and functionality than a home based server, and so the load on the network contributed by each system is also a lot. In addition to this there is he additional necessity for security and backups as compared to the home networks. People usually prefer manual backups on their home networks, but almost all the companies insist on having sch eduled backups for the protection of data. In addition, the systems also need to have security updates with a controlled installation, which is not necessary for a home network, whose security necessities extend maximum to having a basic firewall.As in earlier case, due to data sensitivity, companies prefer to have all of these controlled rather than leaving it to the discretion of the office employees. There is an obvious burden due to the higher cost of installation and maintenance of the system. But this is more than compensated by the quality of security and safety levels given by such a system. Also since, there are only 16 employees in the system, it is logical to have the email server as the same as the network server. This is also true for the web server applications. However, here there is an assumption being taken.It is assumed that the company business is a small size, based on the number of people working there. This may very well not be the case. In addition to this, th e web sever installation might be mandatory on an external system, because of security reasons. For instance, the company might not want its intranet lined with its webserver to provide more security. This case might necessitate the need for a separate web server, though for this report, a single sever is being considered for now. Physical Components In addition to the computer systems and printers, the company needs many additional systems to make a network.First and the most important of this is the server system, which needs be high ended, with high processing power and speed. This is that the system can easily act as a intranet server, a mail server, and also the web server. In addition to this a router is essential for connecting to the internet via the DSL modem. Also there are multiple numbers of cables, based on the systems connected to the network. Since the system is connected via the Ethernet here, the internet being a DSL based one; the corresponding cables are also requ ired.The printer is connected to the server, which takes care of the scheduling the print jobs. The other servers, as mentioned earlier are situated on the main server itself. The figure above shows the scheme of the connection diagram. The above diagram is a very simplistic way of representation of the office network. As mentioned above, the server would be common from email and web applications, and also take care of the intra networking scheme. In addition, the various printers and DSL modem would be added to this server only.The server would need a network operating system and the main security firewalls and the protection schemes like the antivirus would be installed here. Ethernet would be the mode of interconnection in the network. The system can be extended when a new web server is required, which is separate from the present server. There can be another server attached to the present one which would take care of the business related websites etc. The connection would be res tricted so that only the purchase related or feedback related information is passed to the main server, which would then direct this information to the necessary client system.Conclusion In the report mentioned above, there were two types of networking architecture which were analysed. One was the client server architecture, which is one of the oldest networking schemes available. The system finds its use in complex networks having many systems, and necessity for multi-file sharing applications, common or shared database and also security. All these are provided by this system, which the case seen by the company example is being taken here.The operations are very complex with multi-printers and their multiple locations, the necessary for common access to the internet, and also the need for servers for websites and emails. Also the network needed security and will be needed managed access permission for files stored on the network. The restricted type of entry for a network is possib le only for a client and server type of architecture, which is what was proposed for this case. The company being an accounting firm would also need internal data restrictions and security issues, which can only be tacked by this architecture.In contrast, the home networking system is a very simple operation, which needs to have a mere connection to the internet and the use of a printer. There are no constraints of security or access restrictions on this systems and the main application need is a basic file share operation. For such a system a basic, peer-to-peer architecture is sufficient. There is no need for hubs also as there are only two systems. The network does not need any server based system which is too much of overkill here. Hence, using these two examples, the two types of networking architectures are explained here.

Demand Curve and Supply Curve Essay

Demand and supply have been generalized to explain macroeconomic variables in a market economy. The Aggregate Demand-Aggregate Supply model is the most direct application of supply and demand to macroeconomics. Compared to microeconomic uses of demand and supply, different theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. The AD-AS or Aggregate Demand-Aggregate Supply model is a macroeconomic model that explains price level and output through the relationship of aggregate demand and aggregate supply. It is based on the theory of John Maynard Keynes presented in his work â€Å"The General Theory of Employment, Interest, and Money†. It is one of the primary simplified representations in the modern field of macroeconomics and is used by a broad array of economists, from libertarian, monetarist supporters of laissez-faire, such as Milton Friedman to Post-Keynesian supporters of economic interventionism, such as Joan Robinson. Brief history of demand curve and supply curve According to Hamid S.  Hosseini, the power of supply and demand was understood to some extent by several early Muslim economists, such as Ibn Taymiyyah who illustrates- â€Å"If desire for goods increases while its availability decreases, its price rises. On the other hand, if availability of the good increases and the desire for it decreases, the price comes down†. In 1691, John Locke worked on some considerations of the consequences of the lowering of interest and the raising of the value of money. It includes an early and clear description of supply and demand and their relationship. In this description demand is rent: â€Å"The price of any commodity rises or falls by the proportion of the number of buyer and sellers† and â€Å"that which regulates the price of goods is nothing else but their quantity in proportion to their rent. † The phrase â€Å"supply and demand† was first used by James Denham-Steuart in his Inquiry into the â€Å"Principles of Political Oeconomy† which was published in 1767. Adam Smith used the phrase in his book â€Å"The Wealth of Nations† (1776) and David Ricardo titled one chapter of his work â€Å"Principles of Political Economy and Taxation† (1817) On the Influence of Demand and Supply on Price. In The Wealth of Nations, Smith generally assumed that the supply price was fixed but that its value would decrease as its â€Å"scarcity† increased, in effect what was later called the law of demand also. Ricardo, in Principles of Political Economy and Taxation, more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand. Antoine Augustin Cournot first developed a mathematical model of supply and demand in his 1838 Researches into the Mathematical Principles of Wealth including diagrams. In1870, Fleeming Jenkin in the course of â€Å"Introducing the diagrammatic method into the English economic literature† published the first drawing of supply and demand curves including comparative statics from a shift of supply or demand and application to the labor market. The model was further developed and popularized by Alfred Marshall in the textbook â€Å"Principles of Economics† (1890). The Standard demand curve and the aggregate demand curve The standard demand curve represents the quantity of a good that a consumer will buy at a given price, holding all else constant. For example, consumer A might buy zero oranges at $1 each, one orange at 75 cents each, and two at 50 cents each, while consumer B might buy one at $1, two at 75 cents, and three at 50 cents. When charted on a grid with price on the vertical axis and quantity purchased on the horizontal axis, these points form the individual demand curves for consumers A and B. The aggregate demand curve represents the total quantity of all goods (and services) demanded by the economy at different price levels. An example of an aggregate demand curve is given in Figure 1. The vertical axis represents the price level of all final goods and services. The aggregate price level is measured by either the GDP deflator or the CPI. The horizontal axis represents the real quantity of all goods and services purchased as measured by the level of real GDP. Notice that the aggregate demand curve, AD, like the demand curves for individual goods, is downward sloping, implying that there is an inverse relationship between the price level and the quantity demanded of real GDP. The standard supply curve and the aggregate supply curve The standard supply curve is a graph showing the relationships between the price of a good and the quantity supplied. The supply curve slopes upward because other things equal, a higher price means a greater quantity supplied. The aggregate supply curve shows the relationship between the price level and the quantity of goods and services supplied in an economy. The equation for the upward sloping aggregate supply curve, in the short run, is Y = Ynatural + a (P – Pexpected). In this equation, Y is output, Ynatural is the natural rate of output that exists when all productive factors are used at their normal rates, â€Å"a† is a constant greater than zero, P is the price level, and Pexpected is the expected price level. This equation holds only in the short run because in the long run the aggregate supply curve is a vertical line, as output is dictated by the factors of production alone. An aggregate supply curve is shown in Figure 2. The aggregate supply curve equation means that output deviates from the natural rate of output when the price level deviates from the expected price level. The constant, a, shows how much output changes due to unexpected deviation in the price level. The slope of the aggregate supply curve is (1/a) which depicts the short-run aggregate supply curve and the long- run aggregate supply curve. The vertical axis is the price level. The horizontal axis is output or income. The short-run aggregate supply curve is downward sloping with slope equal to (1/a) while the long-run aggregate supply curve is vertical with no slope. The reason that the short-term aggregate supply curve is upward sloping is a bit more complex. Factors that determine the slope of AD-AS curve model The slope of AD curve reflects the extent to which the real balances change the equilibrium level of spending, taking both assets and goods markets into consideration. An increase in real balances will lead to a larger increase in equilibrium income and spending, the smaller the interest responsiveness of money demand and the higher the interest responsiveness of investment demand. An increase in real balances leads to a larger level of income and spending, the larger the value of multiplier and the smaller the income response of money demand. This implies that the AD curve is flatter, smaller is the interest responsiveness of the demand for money and larger is the interest responsiveness of investment demand. Also, the AD curve is flatter; the larger is the multiplier and the smaller the income responsiveness of the demand for money. We know that aggregate demand is comprised of C(Y – T) + I(r) + G + NX(e) = Y. Thus, a decrease in any one of these terms will lead to a shift in the aggregate demand curve to the left. The first term that will lead to a shift in the aggregate demand curve is C(Y – T). This term states that consumption is a function of disposable income. If disposable income decreases, consumption will also decrease. There are many ways that consumption can decrease. An increase in taxes would have this effect. Similarly, a decrease in income–holding taxes stable–would also have this effect. Finally, a decrease in the marginal propensity to consume or an increase in the savings rate would also decrease consumption. The second term that will lead to a shift in the aggregate demand curve is I(r). This term states that investment is a function of the interest rate. If the interest rate increases, investment falls as the cost of investment rises. There are a number of ways that investment can fall. If the interest rate rises, say due to contractionary monetary or fiscal policy, investment will fall. Similarly, in the short run, expansionary fiscal policy will also cause investment to fall as crowding out occurs. Another interesting cause of a fall in investment is an exogenous decrease in investment spending. This occurs when firms simply decide to invest less without regard for the interest rate. The term variable that will lead to a shift in the aggregate demand curve is G. This term captures the whole of government spending. The only way that government spending is changed is through fiscal policy. Recall that the budgetary debate is an ongoing political battlefield. Thus, government spending tends to change regularly. When government spending decreases, regardless of tax policy, aggregate demand decrease, thus shifting to the left. The fourth term that will lead to a shift in the aggregate demand curve is NX(e). This term means that net exports, defined as exports less imports, is a function of the real exchange rate. As the real exchange rate rises, the dollar becomes stronger, causing imports to rise and exports to fall. Thus, policies that raise the real exchange rate though the interest rate will cause net exports to fall and the aggregate demand curve to shift left. Again, an exogenous decrease in the demand for exported goods or an exogenous increase in the demand for imported goods will also cause the aggregate demand curve to shift left as net exports fall. An example of this type of exogenous shift would be a change in tastes or preferences. The aggregate demand curve also can shift right as the economy expands. When the aggregate demand curve shifts right, the quantity of output demanded for a given price level rises. Therefore, a shift of the aggregate demand curve to the right represents an economic expansion. A shift of the aggregate demand curve to the right is simply affected by the opposite conditions that cause it to shift to the left. A change in one or more of the following determinants of aggregate supply will shift the aggregate supply curve in the short run. – Change in the input prices (domestic or imported resources price), change in productivity, change in legal institutional environment (business taxes and government regulation). An increase in short-run aggregate supply will shift the curve rightward; a decrease will shift the curve leftward. The long run aggregate supply curve is vertical. Similarities between the Ad-AS curve model and the standard demand-supply curve model The conventional â€Å"aggregate supply and demand† model is actually a Keynesian visualization that has come to be a widely accepted image of the theory. The Classical supply and demand model, which is largely based on Say’s Law, or that supply creates its own demand depicts the aggregate supply curve as being vertical at all times. The both demand curve and the aggregate demand curve is negatively sloped from left to right and both curves represent the law of demand. The short-run aggregate supply curve or SRAS curve has similarities the standard supply curve. Both are positively sloped. Both curves relate price and quantity. Differences between the Ad-AS curve model and the standard demand-supply curve model In aggregate demand curve, there is no substitute effect because we cannot substitute all goods. But in standard demand curve it exists. The aggregate demand curve has no income effect because a lower price level actually means less nominal income for the resource suppliers’ e. g. lower wages, rents, interests, and profits. But in standard demand curve it exists. The major differences between the standard supply curve and the aggregate supply curve are as follows- for the market supply curve, the vertical axis measures supply price and the horizontal axis measures quantity supplied. For the short-run aggregate supply curve, however, the vertical axis measures the price level (GDP price deflator) and the horizontal axis measures real production (real GDP). The positive slope of the market curve reflects the law of supply and is attributable to the law of diminishing marginal returns. In contrast, the positive slope of the short-run aggregate supply curve is attributable to: (1) inflexible resource prices that often makes it easier to reduce aggregate real production and resource employment when the price level falls, (2) the pool of natural unemployment, consisting of frictional and structural unemployment, that can be used temporarily to increase aggregate real production when the price level rises and (3) imbalances in the purchasing power of resource prices that can temporarily entice resource owners to produce more or less aggregate real production than they would at full employment. Conclusion Whereas the standard supply and demand curve model discusses on individuals, the aggregate supply and demand curve model works with the whole economy. This model is built on the assumption that prices are sticky in the short run and flexible in the long run. This model also highlights the role of monetary policy. This model shows how shocks to the economy cause output to deviate temporarily from the level implied by the standard model. By this model, we can observe the economy more efficiently than before.
