Changes in American Foreign Policy, 1880-1920

Reflective of changes throughout the world, and sometimes in response to them, America underwent a great deal of transformation in the period from 1880-1920, especially in the various areas of foreign policy. With this transformation in mind, this paper will discuss several key areas in American foreign policy from the late 1800s to early 1920s. At the conclusion of the paper, the reader will have better understanding of the topic and hopefully will study the topic in greater depth.With the topic in mind, the paper begins with an overview of American foreign policy in the early days of the period being presented. American Foreign Policy Prior to the Late 1890s Prior to the late 1890s, American foreign policy was mostly focused on ways for America to insulate itself from the rest of the world, evidenced by the purchase of Alaska from Russia in 1867, the taking of the Midway Islands off of Hawaii as an American territory in 1867, and later, the acquisition of Hawaii as a territory.What these strategic moves show is an American initiative to put as much distance between the United States and the other nations of the world as possible. At that time in history, oceans and land borders were an effective barrier against foreign interference, more so than today. Reasons for the Change in American Foreign Policy in the 1890s Once America entered the 1890s, attitudes about foreign policy began to shift from the previous desire for isolationism, for a variety of reasons.In the specific interest of democracy and its proliferation around the world, the United States found it necessary to look beyond its own borders for fertile land to plant the seeds of democracy, as most historians agree that the United States frontier was officially â€Å"closed† as of 1890, making it necessary to look elsewhere to spread American influence if so desired. The United States also had legitimate reasons to be concerned about the foreign policies of others in the world, illustrated by the expansion of European influence in Asia and Africa, as well as economic concerns that affected foreign policy.The 1893 depression that rocked the American economy necessitated a way to distract the people from their domestic problems, as well as ways to find international markets for American products as a way of relieving the economic ills brought by the depression of 1893. Domestic industries also had an acute need for raw materials, many of which could only be obtained overseas, and the only way to effectively obtain them from overseas was to build a relationship with foreign countries, which admittedly was not part of foreign policy to any measurable extent up to this time.Prominent Americans Involved in the Formation of Foreign Policy Whether in an official government function, or as a result of other actions, there are several noteworthy Americans who shaped the course of foreign policy at this time, and indeed changed the course of history to a substantial extent. Governm ent leaders who had a loud voice in regard to American foreign policy during this era were of course President Theodore Roosevelt, as well as powerful senators such as Henry Cabot Lodge of Massachusetts, Secretary of State John Hay who served in this capacity both Under Roosevelt and Woodrow Wilson, and others.In the world of American industry, men such as Andrew Carnegie were held in high esteem for their foreign policy views, as were â€Å"celebrities† such as author Mark Twain. Beyond a shadow of a doubt, one of the most influential â€Å"civilians† in foreign policy at this time was newspaper magnate William Randolph Hearst. Hearst, it is alleged, sensationalized headlines in an effort to ignite the American interest in engaging Spain in what would be come to be known as the Spanish American War, as well as other events.This type of activism played a pivotal role in the shaping of American foreign policy. Foreign Policy in Latin America, Asia and Europe As America undertook a more active foreign policy due to government and private citizen involvement, it encountered challenges from several areas of the world, both relatively close to her borders and overseas. One of the most significant tests to American foreign policy at that time came from Spain, namely in regard to the issue of Cuba.More specifically, Cuba had not gained independence from Spain up to this time, as the rest of Latin America had. Cuban revolt against Spain had been ongoing for many years, but Cuba remained Spain’s only American territory, and was important to the Spanish for its strategic location as well as for its resources in sugar, beef and tobacco. The United States also had substantial business interests in Cuba and therefore desired to confront Spain in regard to possession of Cuba.In 1898, the United States went to war with Spain, a war which ultimately resulting in American victory and possession of Cuba, but at the cost of hundreds of millions of dollars an d thousands of American lives. Upon possession of Cuba, the United States established the Guantanamo Marine and Naval Base in Cuba, which still exists today. Regarding the involvement of America in foreign affairs overseas, following the Spanish-American War which gave America possession of Cuba, America began to move further away from its native soil, acquiring Guam and the Philippines as territories as well.America also became more involved with foreign powers in regard to trade as a result of the acquisition of the Panama Canal Zone, and President Theodore Roosevelt sought to flex American muscle by such displays as the launching of a naval fleet of huge ships which traveled to foreign ports, proudly displaying the American flag as a clear message that America was in a sense â€Å"moving into the neighborhood†. Succeeding Roosevelt in the presidency, Woodrow Wilson’s emphasis on diplomacy and missionary type foreign relations led to American intervention and war in Europe.When World War I first began to erupt in Europe, the United States attempted to stay neutral in the dispute, which was impossible due to America’s wish for neutrality on one hand and the desire to prevent Germany from winning the war on the other. Wilson, attempting to toe the line between American entrance in the war and efforts to assist in the defeat of Germany, tried to be involved without going to war, which he soon learned was impossible, throwing America headlong into World War I.The American entrance into World War I, it should be noted in fairness, was also made necessary by the aggression of other countries. Specifically speaking of German aggression against the United States, German submarines sank the British liner Lusitania in 1915, killing among others 128 Americans, followed by continued German warfare aimed at United States merchant ships on the seas that the United States tried to sail as a neutral nation.There is also evidence of an organized German e ffort to wage war on the United States, which certainly accelerated the American path to World War I. American Foreign Policy as it Appeared Around 1920 In the years around 1920, America’s foreign policy, in a sense coming full circle from the isolationist policies of the early 1890s, seemed to look inward, namely in the area of immigration, and how the huge influx of people from other countries seeking a new life in America was affecting the lives of those already in the country.During the beginning of the 20th century, millions upon millions of people had come to the United States, and as the number of people coming from other countries increased, the opposition to this among Americans increased as well. The United States in the early 1920s was no longer willing to accept huge numbers of immigrants as in the past. With this in mind, several laws were passed to limit the numbers of immigrants allowed admission into the United States, signaling the end of one of the largest m ass migrations of people from many nations to one nation in the history of the modern human race.As immigration slowed to a mere trickle, a small but significant movement of Americans to Europe was taking place, but this was mostly in the area of the intellectuals, artists and authors, who sought the deep cultural history of Europe to stimulate their creativity and quest for knowledge and exposure to ancient cultures. Closing Thoughts In retrospect, American foreign policy from 1880-1920 was truly a vital ingredient in defining the expansion of the United States, as well as establishing democracy as a force to be respected, and in some cases reckoned with, in terms of international foreign relations.In addition, the land acquisitions and strategic alliances that were formed during this era play a part in the economy and security of the United States even today. This being said, as a closing thought, it is intriguing to consider the role that history has in not only defining and expl aining our past, but also setting a course for the future. Therefore, it is the duty of every thinking person to treasure history and learn from it, lest, as the old saying goes, we become condemned to repeat it.

Hp and Compaq merger Research Paper Example | Topics and Well Written Essays - 1250 words

Hp and Compaq merger - Research Paper Example From this view, the successful technology company, rather than regarding its surroundings as fairly stable and internal mechanisms as being of utmost importance, reacts in a converse manner, focusing outwards and embracing change and letting technology lead the way in terms of change. Or, alternatively, the company could also be pulled along by technology rather than being the one doing the pushing. In this type of situation, â€Å"Marketing oriented managers can direct scientists into what appear to be exciting markets with assured high demand. This is often called demand pull. Here innovation, the need, is father to or mother to the new invention† (Burgelman et al., 683). Overall, the HP Compaq merger case seems to show technology pull or demand pull, because it was in fact the popularity of the increasing computer hardware/software manufacturing technology that was pulling the merger into innovation. This is a very dynamic industry, in which variables of competition would f avor a merger between two large pre-existing players, rather than a new entrant. There are many reasons for this, chief among them the extreme costs of entering this saturated market. In the face of competition, Compaq/HP as a merged company has been struggling to capture the market dominance that it needs to survive in this competitive and dynamic type of industry. â€Å"Now the two consulting firms mostly agree that HP has a firm lead. IDC published statistics on Jan. 17 showing that Palo Alto-based HP had 18.1% market share during the three months ended December, while Round Rock (Tex.)-based Dell had only 14.7%. By Gartners count HP had 17.4% market share and Dell takes second place with 13.9%† (Ryst, 2007). Although the merged company is still strong in the market generally, it cannot really afford to keep slipping. Solving this problem means realizing how economics plays a large role in the external environment of HP/Compaq’s market, particularly the PC

Strategy analysis Case Study Example | Topics and Well Written Essays - 250 words

Strategy analysis - Case Study Example The company has a low cost approach, despite being the standard price of the market. The company aims at giving the customers value for their money, while ensuring that the employee welfare is taken into concern. Besides having fair prices, the company has extremely good customer relations. Cliff Bowman argues that there are five routes in defining companies’ strategies (Bowman and Faulkner, 1997). The low price or value strategy involves companies selling on the price factor alone given the little differentiation of the products offered. The low price and the differentiation strategy are similar to the arguments explained by Porter. The focused differentiation aims at offering highly valued products at a substantial premium price. The hybrid approach, on the other hand is the best-cost provider strategy that combines a low cost approach with an emphasis on differentiation. The hybrid approach, according to Bowman, suits the strategy implemented by Southwest

ACTA and Internet Counterfeiting Essay Example | Topics and Well Written Essays - 1250 words

ACTA and Internet Counterfeiting - Essay Example As an e-commerce medium, it is used as a payment medium through PayPal, VISA and other online payment systems. Moreover, it is the medium through which softcopy products like eBooks, software, online courses and other products are delivered. Since most of these activities involve transmission of sensitive information about people and more so customers, the information passing through the internet is encrypted such that the information encoded by the server can only be decoded by the client’s terminal and vice versa (Illing and Peitz, 2006: 102). This means that information being transmitted over encrypted networks cannot be accessed by third parties. This security property of the internet is priceless since it helps to sustain the faith that suppliers and consumers have on the internet; however, it also poses one of the major challenges in regulation of content being transmitted over the internet. It enables the internet to be used for transmission of information, a large port ion of which is unauthorised for electronic transmission (Biagi, 2011). Such information includes transmission of age-inappropriate content, rumours and propaganda that may undermine peace and stability, and copyrighted material. Censorship for inappropriate content can be easily implemented at a country or state level; however, transmission of copyrighted material like music, eBooks and software is hard to control since sharing networks entails use of multiple servers located all over the globe (Hertwig and Maus, 2010: 60). This necessitates the adoption of a common regulatory system, whereby countries work together to enforce antipiracy regulations. This essay discusses the effects of internet infringement of property rights and copyrights and discusses the adoption of ACTA (Anti-Counterfeiting Trade Agreement), especially in the European Union. Technical Factors Historically duplication of copyrighted materials has always happened; however, the internet offered a channel that mad e the process quite easy to achieve with little skill level. Moreover, the vastness of the internet and its high rate of growth make any attempt to control its content an exercise in futility. Moreover, the technical knowledge of computer networking specialists gives them the ability to bypass any efforts by regulators, which is the main reason for proliferation of illegal websites (Woodsworth, 2010: 185). Moreover, developments in the information technology sector resulted in the proliferation of highly efficient but cheap IT equipment, which increased the number of servers, terminals and other devices beyond the scope of regulatory bodies. In order to cover the increased usage of the internet for illegal purposes, all stakeholders had to be incorporated in the process, which was the main motive of the implementers of ACTA. The other factor that leads to a high proliferation of computer piracy of software and other copyrighted materials is the capacity of network connections to wor k in both directions, such that information flows to or from a terminal in the same way it does to a server. This allows network terminals like workstations, personal computers and other devices to be used as sources of data, especially as used in peer-to-peer protocols like BitTorrent (Hunnewell and Garlick, 2007). These networks allow users to share data in their computers with other users without the need for a server; which makes it almost impossible to detect the circulation of copyrighted material since pieces of the software or other content are usually spread throughout the terminals in the networks. In this case, remarkably

Motivating and Maintaining Morale during Downsizing at Rutledge Essay

Motivating and Maintaining Morale during Downsizing at Rutledge Company. The Ethical Selection Dilemma at Integrity Motors - Essay Example For this reason, it implies that a number of employees eventually have their contracts terminated, and it consequently affects their productivity before termination of their employment. Thus, this expose analyses the best practices using the case study about downsizing in Rutledge Company. First, communication is the most important aspect in a firm, and it will be essential in solving problems such as these affecting Rutledge Company. Thus, communicating to employees on how the organization will manage change and informing them on measures that the management will use in determining who to train is crucial in creating an honest environment instrumental for motivating employees. Secondly, assisting the departing employees to find employment in other places will help boost their morale and ensure that the company does not encounter losses in terms of productivity during the downsizing period. Other actions that can increase morale and motivation are providing counseling, establishing f airness by treating all employees equally, and subsequence announcement of downsizing as planned (Mishra & Spreitzer, 1998). The objective of the company should be the elimination of most of the employees who failed to use the technology required for the job. However, the company should make definite decisions that motivate the remaining employees in order to avoid losing some of their talents. First, evaluating this category of employees and identifying their preferences and potential becomes crucial in determining the employees to retain. Therefore, Rutledge Company and its employees should collaborate in developing the best program suited to train the employees who are not using the required technology. In effect, these employees will experience a bond with Rutledge and will start using the latest technology since they participated in developing the plan and they have the feeling of ownership of the plan they helped develop. The best criteria that Rutledge should use during downs izing must encompass employee productivity and competence. In this regard, productivity should be the basis for determining the performance of employees during downsizing, and there should be a performance appraisal in place meant to determine the performance of each employee with the new technology. The performance appraisal, determined by the developers of the technology, will ensure fairness in the retention process. In addition, the fairness will make sure that all employees remained motivated to perform their responsibilities before they knew of their fate at work. It is common knowledge that changing technology in a firm requires properly training the employees. In effect, training will similarly apply to Rutledge Company and its employees. Conversely, retraining employees might improve their morale and motivate them at work. Providing in-service training to the employees will help them learn together with their managers on working while using the new technology. In effect, le arning with their managers and supervisors will help create a â€Å"fellow feeling† to the company, which ultimately motivates the employees and improves their productivity at work since there will be an attachment created in the company. In addition, further training is crucial since it enhances communication within an organization. As previously indicated, communication is crucial since there will be the creation of an environment of trust and openness, which motivates Rutledge’s employees. Case 2: The Ethical Selection Dilemma at Integrity Motors Entrepreneurs and managers realize the importance of hiring the right personnel to run their businesses successfully. In order to

Energy in food lab practical Coursework Example | Topics and Well Written Essays - 1000 words

Energy in food lab practical - Coursework Example However, the results are valid for the determination of the energy content of foods. The energy intake in human beings is dependent on the diet. There is increasing evidence that the dietary energy density is an important characteristic in estimating energy intake. The challenge however lies in the development of methods to derive energy density (Cox and Mela 49). Therefore, the determination of energy density of most diets can be deemed as a multifaceted if not involved process. In connection to this, there are factors that limit the accuracy of the procedure and its totality in estimating the energy density of a given diet. Three methods have been previously documented and compared in the determination of Energy density. The first is all foods and beverages, the second considers only food and caloric beverages and the third is biased towards food only. It is evident from a consideration of each method that there will be significant differences in the energy density obtained. . Fats carbohydrates and proteins are the chief sources of energy in the human diet. Fats and carbohydrates contain hydrogen, carbon and oxygen whereas proteins in addition to these contain nitrogen. The heat released through the oxidation of food is the heat of combustion, and it is widely accepted to be synonymous with its gross energy value. The primary objective of this research was to determine the energy density of bread, mushroom, and oil Bread, oil, mushrooms, distilled water, clamp, boiling tube and burner. Also, thermometer, Heatproof mat, Measuring cylinder, 50 cm3 or 100 cm3 and Mounted needle with wooden handle. In addition, Tongs or forceps for food samples that cannot be impaled Thermometer (–10 Â °C to 110 Â °C) and Eye protection were also used. The food samples of mushrooms and bread were dried before being cut into 1 cm2 or 0.5 cm3. The boiling tube was held in position using a clamp stand and 20ml of water transferred into it.

A View From The Bridge Essay Example for Free

A View From The Bridge Essay A View from the Bridge was written by Arthur Miller in 1955. The play is a modern tragedy with some elements of an Aristotelian tragedy. The play is set in the 1950s in the gullet of New York which is Red Hook.  In this essay I am going to explore if the protagonist, Eddie Carbone, is guilty for his downfall; which then leads to his death. A tragic hero has a fatal flaw which leads to his downfall, in Eddies case, he is attracted to his niece. This causes him to be overprotective and not let her meet anyone else, as he wants her for himself. The tragic heros downfall is brought about by ignoring advice; In Eddies case, he doesnt listen to Alfieri, the lawyer and chorus of the play, when he tells him to let Catherine go. My first impression of Eddie is a tall, big and quite overweight man, with little hair and a slowly dying face. He is an outgoing and hardworking man who provides for his family. I got some of these impressions because the chorus, Alfieri, describes him as, He is forty a husky slightly overweight longshoreman. The first person he talks to in the play is his niece, Catherine. At first he is caring when he comments on her new dress. But then he becomes a bit protective about her wearing it as he thinks it is too short and that men outside would stare. He is also reluctant to let her to go to work at first but when he sees she is sad he lets her do it, which shows us that he is more willing to make his niece happy than his wife. He talks to his wife, Beatrice like he would to any other wife but he does not go over to her to give her a hug or a kiss, just simply tells her something. But when he does, he sometimes holds her hands affectionately. This tells us that he expresses his feelin gs more easily in gestures than in words. Before Marco and Rodolpho arrive, Eddie is not too fond of them staying at his house, he complains that he may end up sleeping on the floor because of them. But then he talks about it being an honour for letting them stay over. When the cousins actually arrive, his attitude towards them changes dramatically. Earlier on he was saying Listen, as long as they know where there gonna sleep, and when they arrive he greets them;  Youre welcome, Marco, we got plenty of room here. Katie, give them supper, heh? Later on he only comes to address Marco only as he realises that Catherine is attracted to Rodolpho. He is coming more and more to address Marco only. He notices this as she keeps talking about Rodolphos facial appearance. The fall of Eddie Carbone begins when the cousins moved in. Rodolpho and Catherine are instantly attracted to each other, which angers Eddie very much as he is also attracted to her. Beatrice worries that Eddie dislikes Rodolpho because he likes Catherine, he responds, He sings on the ships, didja know that? This gives us a hint that he is trying to find things wrong with Rodolfo.  After this he visits Alfieri, the lawyer. He goes to ask him if he would be able to stop Rodolfo and Catherine marrying each other, but Alfieris advice to him is the child has to grow up and go away, and the man has to learn to forget. Because after all, Eddie what other way can it end? One other thing that Alfieri says hints at the truth, She wants to get married, Eddie. She cant marry you, can she? Eddie replies Whatre you talking about, marry me! I dont know what the hell youre talking about! He obviously knows what hes talking about, and Beatrice knows as well. The violent reaction from Eddie shows us that he fells ashamed that he loves his niece and fears that he will lose his dignity and respect.  Eddie doesnt listen to his advice but leaves the office in a dilemma. Knowing he cant do anything about Rodolfo, his attitude towards him changes dramatically. He stops talking to him in a civil manner and only speaks to mock him, such as when Rodolfo says, Lemons are green, and Eddie replies, I know lemons are green, for Christs sake. He says this almost to point out that Rodolfo is stupid. Every time he criticises Rodolfo he seems to look for support in his older brother, Marco. When he tries to teach Rodolfo how to fight, we see Marco being protective of his brother. When Eddie tries to land a punch on Rodolfo, the stage directions say it mildly staggers Rodolfo, Marco rises. After they have finished, Marco has his own test of masculinity. Marco says Can you lift this chair, a seemingly easy task. But Eddie cannot complete it and Marco carries on with showing him as the stage directions say, Rodolfo and Catherine have stopped dancing as Marco raises the chair over his head. Marco is face to face with Eddie, a strained tension gripping his eyes and jaw, his neck stiff, the chair raised like a weapon over his head and he transforms what might appear like a glare of warning into a smile of triumph. This shows us that Marco is no longer in support of Eddie and it is also a sign that he will defend and protect his brother if he is harmed. This leaves the audience tense at the end of Act One, which will make us focus more on the play. We become anxious about what happens from here on. We also know that a tragedy or something that will lead up to it, is going to occur in the beginning.

Growth Factors in Periodontal Regeneration GROWTH FACTORS IN PERIODONTAL REGENERATION ABSTRACT : Periodontitis and all periodontal diseases are bacterial infections that destroy the attachment fibers and supporting bone. Left untreated, these diseases can lead to tooth loss. The main cause of periodontal disease is a bacterial plaque, many options are available to treat this disease including non-surgical,surgical,and recent regenerative materials. GFs are natural biological mediators that regulate key cellular events that are part of the process of tissue repair and regeneration. Recent advances in the areas of cellular and molecular biology allowed better understanding of the functions of GFs and their participation in the different phases of wound healing. In vitro and in vivo studies have confirmed that GFs can enhance the capacity of tissues to regenerate by regulating cell chemo attraction, differentiation and proliferation. This review focuses on five growth factor families that have potential for inducing periodontal regeneration based on their ability to stimulate osteo blast and periodontal ligament cells in vivo and vitro. Key words: platelet-derived growth factor, insulin-like growth factor, transforming growth factor-beta, fibroblast growth factor, and bone morphogenetic protein. INTRODUCTION : Periodontitis is a widely prevalent inflammatory disease of the tissues supporting the teeth, characterized by a progressive loss of bone and attachment. The ultimate goal of periodontal therapy is the regeneration of periodontal tissues, which consists in stimulating new cementum formation, new alveolar bone apposition, and a functionally-oriented periodontal ligament reconstruction. Conventional treatment procedures may be ineffective in achieving bone regeneration, leaving both the clinician and the patient dissatisfied with the outcome. Growth factors (GFs) have long been believed to have the potential to accelerate the healing process and, therefore, enhance tissue regeneration in challenging clinical scenarios.1 MODE OF ACTION OF GROWTH FACTORS: To evoke a biologic effect, a growth factor must be synthesized by an originating cell, travel to its target receptor, interact with target receptor, or binding protein, and activate second messengers or terminal effectors.2,3 Local mode of action is more associated with the term growth factor and involves Paracrine, Autocrine, Juxtacrine, and Intracrine modes. Autocrine mode of action – Growth factors synthesized by one cell, secreted in a soluble form outside the cell and then bind to surface receptors on the same cell to evoke an effect is autocrine mode of action. Example includes: TGF ÃŽ ², which are produced and act on epithelial cells, and BMP’s, which are produced and act on osteoblastic cells. (fig 1) Intracrine mode of action–Growth factors produced by one cell and not secreted, but acts intracellularly to facilitate its effects is intracrine mode of action. (fig 2) Paracrine mode Growth factorsproduced by one cell, with receptors present on another cell in the local micro environment is the paracrine mode of action. Here the mediators are secreted in soluble form and binds to its receptors on the target cell to evoke its effect. (fig 3) Juxtacrine mode It is similar to paracrine effects except that the factor produced by the cell of origin is cell surface bound and requires cell contact by the target cell to evoke a response. (fig 4) RECEPTORS FOR GROWTH FACTORS:4,5 For a growth factor to exert an effect, its designated receptor must be present in sufficient quantity, orientation, and functional activity to transmit appropriate stimuli. Growth factor receptors can be divided into 2 broad categories: Cell surface receptors Intracellular receptors The most common prototype growth factor receptor is the cell surface receptor, which can be further divided into three main categories: G- protein linked Receptor tyrosine kinases Serine threonine receptor kinases POTENTIAL ROLES OF GROWTH FACTORS IN PERIODONTAL REGENERATION: To stimulate cell proliferation. E.g. Platelet derived growth factor (PDGF). To enhance function of cells and cell differentiation. E.g. Bone morphogenetic protein (BMP). To stimulate matrix synthesis. E.g. Transforming growth factor- ÃŽ ² (TGF- ÃŽ ²). To act as co-factors for gene expression. DISADVANTAGES OF GROWTH FACTORS: They were intended to be made by cells, stored than used locally. They have short half-lives i.e., when used as drug, doses must be greater than actual in vivo concentrations. They affect various cells in individual ways i.e., cells growing in high concentrations of growth factor had an increased susceptibility to cell death upon growth factor withdrawal. They need a delivery system for sustained or, controlled release (in low concentration) of a biologically active growth factor or, cocktail of growth factors. POLYPEPTIDE GROWTH FACTORS : Polypeptide growth factors are a diverse group of hormone-like agents that regulate growth and differentiation through cell surface receptors. They are generally represented by homologous families containing several members with distinct overlapping receptor interactions and hence, responsive tissue specificities. Similarly, their receptors are also clustered in family groups of sequence-related proteins. COMMON FEATURES OF POLYPEPTIDE GROWTH FACTORS :6 Natural cell products: Growth factors are natural cell products that are released or activated when cell division is needed.This action typically occurs during such events as wound healing or, tissue regeneration. Local actions: With few exceptions,growth factors are locally acting. Receptor activity: Because growth factors cannot diffuse across the cell membrane, growth factors must exert their activity by first binding to high-affinity cell membrane receptors.The capacity of a cell to respond to a given factor is therefore dependent on the presence of these receptors. Regulation: The production of polypeptide growth factors is tightly regulated in normal cells. In contrast, unregulated production of growth factor is thought to be an important component of proliferative disorders, such as fibrotic disease and cancers. Multifunctional activities: Polypeptide growth factors are multifunctional, meaning that they may stimulate a wide variety of cellular activities, which include growth, migration, differentiation and production of extracellular matrix proteins. Mechanism of action: In some cases, growth factors can stimulate the same cell that synthesizes the molecule (autocrine stimulation) or can affect nearby cells (paracrine stimulation). Regeneration: Tissue regeneration in vivo probably reflects the combined effect of several different growth factors. GROWTH FACTOR APPLICATIONS FOR ORAL AND PERIODONTAL TISSUE ENGINEERING : Therapeutic application of growth factors to restore damaged tissues aims at regeneration through biomimetic processes, or mimicking the processes that occur during embryonic and post-natal development.7 The complexity of these events suggests that creating an optimal regenerative environment requires the combination of different growth factors as found in natural reparative processes. The use of a single recombinant growth factor may also induce several molecular, biochemical and morphological cascades that will result in tissue regeneration.8 The most studied growth factors for periodontal regeneration have been PDGF, IGF, FGF-2, TGF-ÃŽ ² and different BMPs. SI. NO GROWTH FACTOR ALTERNATIVE NAMES SOURCE 1 Platelet-derived growth factor Fibroblast-derived growth factor. Glioma-derived growth factor Degranulating platelets Endothelial cells Smooth muscles Macrophages- Fibroblasts 2 Insulin-like growth factor Erythropoetic factor Growth-promoting activity for vascular endothelial cells Macrophages- Osteoblasts- Plasma stored in bone 3 Transforming growth factor-ÃŽ ² Epithelial cell specific growth inhibitor Tumour-inducing factor-1 Platelet ÃŽ ± granules 4 Fibroblast growth factor family Heparin binding growth factor Macrophage and osteoblasts stored in bone. PLATELET DERIEVED GROWTH FACTOR: The PDGFs are a family of dimeric disulfide – bound growth factors that exert their biologic effects by activating 2 structurally related tyrosine kinase receptors, the PDGF- ÃŽ ± and PDGF – ÃŽ ² receptors. PDGF was the first growth factor to be evaluated in preclinical periodontal and peri-implant regenerative studies. Proliferation, migration and matrix synthesis were observed on cultures of periodontal cells stimulated by PDGF, including gingival and PDL fibroblasts, cementoblasts, preosteo-blasts and osteoblastic cells [9-14]. These effects were shown to be time- and dose dependent 14. The PDGF family is composed of four growth factors: PDGF- A, -B, and the most recently discovered PDGF-C and -D 15. All of these participate in the wound-healing process, but, until now, only the three isoforms PDGF-AA, BB and AB were evaluated in periodontal therapy. PDGF-BB is the most effective on PDL cell mitogenesis and matrix biosynthesis 16,17. INSULIN LIKE GROWTH FACTOR: These are a family of single chain serum proteins that share 49% homology in sequence with pro- insulin. IGF-1 and IGF- 2 are two polypeptides from this group. IGF-1 acts as progression factor, also stimulates bone formation and have an effect on periodontal ligament cells. IGF-I is also important for bone remodeling and maintenance of skeletal mass and plays significant role in age-related osteoporosis. IGF-1 is capable of preventing apoptosis in fibroblasts by activation of multiple signal transduction pathways. IGF-1 has also been shown to regulate DNA and protein synthesis in periodontal ligament fibroblasts in vitro and to enhance soft tissue wound healing in vivo. Furthermore, studies have suggested variable responses of periodontal tissues to IGF-1 depending upon anatomical sites and a differential involvement of IGF-1 in periodontal wound healing and regeneration.18 FIBROBLAST GROWTH FACTOR: The angiogenic and fibroblast stimulatory properties of FGF-2 during wound healing and its chemotactic and proliferative effects on PDL cells suggest its use for periodontal regenerative therapeutic approaches19,20. In preclinical studies, this growth factor was evaluated for the treatment of different types of periodontal bone defects, in dogs and non-human primates. Despite different concentrations of FGF-2 and different delivery systems used in the studies, all showed an improvement in the periodontal tissue regeneration, compared with control groups. Studies that evaluated more than one concentration of FGF-2 suggested that its effects are dose dependent.21,22 TRANSFORMING GROWTH FACTOR ÃŽ ²: It is a member of a large family of biologically active protein hormones that are structurally related but differ markedly in their function. TGF ÃŽ ² consists of 2 subunits held together by covalent bonds. Five different genes are identified that encodes TGF- ÃŽ ² polypeptide TGF-ÃŽ ² has 5 closely related isoforms in vertebrates, out of which 3 are found in mammals (TGF-ÃŽ ²1, TGF-ÃŽ ²2, TGF-ÃŽ ²3). The three major activities of TGF-ßinclude inhibition of cell proliferation, enhancement of extracellular matrix deposition and the exhibition of complex immune regulatory properties. It is a major regulator of cell replication and differentiation. It can stimulate or inhibit cell growth. It can also modulate other growth factors like PDGF, EGF and FGF. It inhibits epithelial cell proliferation and stimulates mesenchymal cells. TGF-ÃŽ ²1, the most abundant isoform of the TGF-ÃŽ ² family and found primarily in the platelets and osseous tissue, has been used for this application.It has a role in recruiting and stimulating osteoprogenitor cells to proliferate and suggests to support periodontal wound healing and regeneration.23 BONE MORPHOGENETIC PROTEINS: The name Bone Morphogenetic Protein was given in 1965 by Urist .Bone morphogenetic proteins (BMPs) are a group of regulatory glycoproteins that are members of the transforming growth factor-beta superfamily.24They stimulate angiogenesis and migration, proliferation and differentiation of mesenchymal stem cells into cartilage and bone forming cells. More than 20 BMP-related proteins have been identified, several of which induce bone formation.25 In the field of periodontal regeneration, much of the research interest has focused on BMP-2, BMP-3 (osteogenin), and BMP-7. Recent studies have utilized recombinant human BMP to determine their potential for correcting intrabony, supra-alveolar, furcation, and fenestration defects. BMPs also show much promise in promoting dental implant wound healing.24 GROWTH FACTOR DELIVERY SYSTEMS: Several matrices and delivery systems have been used and evaluated for their efficacy and biocompatibility as carrier for growth factors. Two common types of polymeric materials used in growth factor delivery strategies are natural collagen-derived materials and synthetic polymers of lactic and glycolic acid (i.e., Poly [lactide-co-glycolide]). Extracellular matrix-derived macromolecules such as collagen have been used for many years in biomaterial application, and it is now possible to create artificial analogues of extracellular matrix proteins using recombinant DNA technology.1 Carriers can be of different types such as solids, gels or combinations.25A variety of new injectable materials such as hydrogels are also being developed for growth factor delivery applications and have been of special interest. These injectables are especially attractive because, in clinical application, they can allow for minimally invasive delivery of inductive molecules.1 CONCLUSION: Growth factors may regulate the repair and/or regenerative process which are impaired in presence of bacteria and their products in periodontal disease. Thus, the objective of growth factors administration in the treatment of periodontitis is to mimic the normal developmental process enhance normal wound healing response to promote complete regeneration of all attachment structures. Basic and clinical research is in progress to evaluate the role of growth factors in periodontal wound healing. BIBLIOGRAPHY: DARNELL KAIGLER, GUSTAVO AVILA, LESLIE WISNER-LYNCH, MARC L.

Table Manners Cultural Differences

Table Manners Cultural Differences Thesis statement: All of us know that diet is very important in our daily life. It can can reflect a nations tradition and culture. However, each country in which geographical, environmental, and cultural and ethnic customs, which has a different concept of diet and dietary practices, and ultimately the formation of the differences in diet culture. Of cause, the table manners appear in our life everyday. They are witness of the history of dietary cultures for thousands of years, are the sign that a country or nation from ignorance and backward towards civilization and progress. Research achievement has a lot on the table manners, and in this passage, the author will stress on the analysis of their differences and the formation cause of the differences. Abstract: The different of the philosophical thoughts and the various kinds of social factors make some differences in Chinese and Western table manners. In China, a banquet, whatever the purpose, there will be a kind of form. Everyone sitting around the table and the delicacy is put in the center of the table. Not only it is a good taste, but also it is a communication medium for people. People toast each other and let food each other. It embodies the mutual respect and the virtue of humility. This way is easy to communicate with others. However, the western table manners are more cumbersome and canonical. Every people has his own service plate, no matter what dish has, they eat by themselves. Westerners drink also depend on their own thoughts, such as Whisky, Cocktails, Brandy, they can drink what they like. It embodies the respect of personal willingness. In this paper, we will talk about Chinese and western table manners and finding out the reasons. The purpose is to improve our intercultural communication ability by means of doing the research on the differences dietary culture between China and west in table manners. 1. Introduction In the 21st century, intercultural communication has become an indispensable content in peoples life. Cooking culture and table manners play a significant role of nonverbal culture in cross-cultural communication. Because of the Chinese people and Westerners have different life styles, the way of thinking, culture, so the table manners between china and western also show a big difference. Chinese table manners have a long history, At the time of the ancient times, table manners had a quite complete system. They took an important part in the past and still have a deep influence in the modern society. Western table manners originated in the 20 century. Italian culture came to France, table manners and menu turned to be more elegant and delicate, from that time, books of etiquette are published gradually. Today, table etiquette is still spreading in Western countries. The table manners in Western countries have influence on Chinese table manners because of the communication. In order to protect our table culture, we can make the two table manners get together, which is good for us to communicate with foreigners. So, it is necessary for us to know the differences of the two table manners and analyze the causes of the different the two table manners between Chinese and Western. 2. The importance of table manners in international cultural communication As Chinese reform and opening quicken markedly, international cultural communication also increases quickly. We must be willing to communicate and be tolerant of views that differ from our own. Our abilities are improved according to international communication. In the society, we do many things successfully on table. For example, when we meet important person, or we have important thing, we could ask the relevant people to have dinner, and discuss on the table. So we must know the table manners. Moreover, if we have a dinner with the Westerners, we should understand the Western table manners well. Because the Western table manners is different from Chinese. On the table, no matter what country the people come from, they could feel the respect from the table manners. Today, transnational cultural communication is so frequent that table manners become more and more important. Not only the whole dining process more harmonious but also status of customers more obvious and their communic ation more convenient by the table manners. For foreign language learners, it is quite useful to know the differences of Chinese and western dietary culture. We can not only increase the understanding of the table manners culture, but also improve the success of intercultural communication, which can help to avoid misunderstandings and communication disorder because of inappropriate behavior. 3. The differences table manners between China and Western countries 3.1 The differences in arrival of time When talking about the time, the Chinese and Westerners have different views. In China, we dont pay much attention on the time. We dont have specific demands about arrival time. To arrive earlier, on time or a little late are all allowed. In fact, we often get to the place where we have a dinner at a litter late time. Because most of us think the host should wait for guest and it is a way to respect for others. The Westerners think both of the time and money are very important, so they always make time and money bonded together. There is a saying goes said that Time is money , and the saying goes has become deeply in the Westerners mind. Therefore, they cherish as far as possible, they plan and manage their time carefully. The Westerners are often filled with a sense of urgency of time. All of them have a interest that they go to some parties in free time. If the westerners have to go to somewhere to have a dinner with others, they must arrive there on time. Frequently, when they want to have a dinner at ones home, they usually get earlier for five minutes. In their opinion, it is not very polite for you to get much earlier, maybe the hostess is so busy doing preparation for the dinner that is not suitable for you to reach at that time. 3.2 The differences in seating arrangement Both in China and in the west, people are particular in seating arrangement of formal banquette. In the Chinese banquets, we prefer to the round table . If there is just a round table in the family dinner, it has no table order. If we join a formal dinner, our seating should comply with the rule. Traditionally, Chinese use square table and the seats, which is look towards to the door is the most important, while seats on both sides are partial seats. So, the elderly and the guests of honor or high status should sit at the seat facing the main door. Then guest of honor sit on the right of the host and deputy chief gust on the left. While, as for the dinning of less than five people, its table setting can follow those four rules: right is honor and the left is low; the middle seat is senior; the seat of facing the door is the top; flexibility arrangement. In Western countries, people usually use long table. Host and hostess sit at both ends, and the guests of honor sit besides them. Then ordinary guests sit along with them. That is to say, the one who is more nearer to the host, the more important he is. In the informal party, it follows that women is first. Seat arrangement should treat the hostess as benchmark, and the most important guests should sit at the upper right of the hostess and the wife of him sitting at the upper right of the host. If a man and a woman have a diner, the man should let the woman sit on his right and dont let she sit near to the passageway; anyway the man need to let the woman sit inside. When two people have a dinner, the senior sit inside.When two men with a woman, men should let woman sit in the middle place. Besides, men should remove the chairs and let women sit first. In a word, women are very important in the seating arrangement. 3.3 The differences in tableware As everyone know people use chopsticks in China, and chopsticks are the most significant tableware for Chinese. Usually, they are traditionally held in the right hand, even by left-handed people. Although chopsticks may now be deployed by either hand, left-handed chopstick use is considered improper. Besides, there are also some rules to abide by when using it. For example, before dinner, chopsticks must be put on the right of rice bowl tidily. While after the meal, it should be placed in the middle of rice bowl, and when talking with other people, we should put down our chopsticks. It is a polite action to others. When take food for others, we ought to use the public chopsticks. In Western countries, people use knives and forks. When eating western-style food, a knife should be held in the right hand and a fork should be held in left hand. Whats more, the different ways knives and forks place have different meanings. For example, you have to leave for a while when you have a meal, you can put the knife and fork separately as a triangle. The service person will not receive your plate. If you have already finished the meal, you should make the knife and fork parallelled. Bread is taken in the fingers and laid on the side of plate or the edge of the large plate. It is never taken with a fork. Butter is taken from the butter dish with the butter knife and placed on the side of plate, not on ones bread. Well, Chinese use chopsticks and westerners use knives and forks. However, they also represent the difference between both collectivism and individualism. Westerners use knives and forks to cut food and separate it to represent individualism. The Chinese use chops ticks to grasp the entire food to mean unity and collectivism. 3.4 The differences in order of serving Chinese order of serving: the first are cold dishes, beverage and wine; then the hot dishes; next staple food; at last the sweets and fruit. Sometimes, there are many tables, each table should be on every dish at the same time. The order of serving still keep the traditional, first hot and later cold. Besides, hot dishes should be served from the left side opposite the seat of the guest of honot. The dishes like whole chicken, whole duck, and whole fish cant put their heads and tails toward the host seat. In the banquet, each dish like slide show, each time a dish is served. Nevertheless, there are some tips: in the wedding banquet or other red banquet, the plates on the table can be overlapped, and meaning that a good thing comes again and again. While, in the White Banquet like funeral, the plates cannot be overlapped, I think you can guess the reason. Western serving steps are usually like that: bread and butter, cold dishes, soup, seafood, main course, dessert, coffee and fruit. When you eating the cold dishes, the soup and bread should be eaten at the same time. In Western, the cold dishes are known as appetizer dish, served as the first course to eat with an aperitif. And soup includes stains soup and cream soup. The main course has chicken, beef, fish and pork and so on. The dissert always has ice-cream, pudding etc. 3.5 The differences in having dinner on table In China, food should be taken by the guest firstly. If you want to eat some food, you could not take too much. The men could give service to women. When you take food, you could not glance left and right and you could not choose one by one in the public dishes. If you eat with many people, you could have comity with everyone. The food which you want to eat and you cant take, you should ask other people to help you to take. Please avoid leaving seat to take by yourself. Chinese table manners atmosphere is lively, people like chatting over eating. Your utterance should be elegant, scholarly and euphemistic. But talking and laughing loudly is not polite. While eating, the older is first, when a dish served, the young can t eat until the elder eat. Chinese table s atmosphere is lively, people like chatting over eating. But talking and laughing loudly is not polite. hen a person has a cough, he or she should turn his or her back. Before you have a drink, you should drink a toast to the e lder and the guest. In West, men should move the seat for women. People always talk with their neighbors when eating, they dont talk loudly. Usually, people have a talk after the main food that the time of they eat dessert. Using the knife and folk cant make a sound. They do not use their own utensils for others to take their food; do not cut food on a plate after a good use of all right hand fork to eat; do not put the bones and food that dont eat on the floor or on the tablecloth, while put them on the on the plate of iceberg. Besides, the polite way is eating out the food on your plate. 3.6 The differences in leaving the table In China, only can the master sign the end of banquet. After the master and guest leave seat, the other guests can leave. Then, the master should be to see guests off at the gate, and the guests should express their thanks to the master. If the guests want to goodbye to host in the midway of the banquet, they just say good-bye to the master or give a nod as a signal to others. At the end of the banquet in Western countries, people should pick up the napkin from the leg, fold optionally, put the napkin on left of the table, and then get up for leaving. After having a meal, the host and hostess should leave before the other guests leave. When leaving, people should help elders or ladies to move the seats, and thank to the master when they say goodbye. If you want to be more cautious, you can thank by phone or card again. The causes of different table manners between the West and China 4.1 The different cultural connotations Culture will affect peoples view on things. Different country has its different culture, so it is obviously that the thinking model between China and western are different. The Chinese culture pays more attention on ones intuition, and the Western culture leans to logic and analyze. As to the traditional of the culture, Chinese people especially believe their own intuition. They insist the experience and feeling during the thing, this phenomenon also happens in the communication between west and east. In China, thousands of cultural tradition is reflected in Confucianism, Taoism and Buddhism. The Confucian thought mainly emphasized benevolence, righteousness, propriety, wisdom, faith; Taoists advocated natural and clean; Buddhist is advocated merciful, purdue beings, harmony without. From this we see that what is tasty to a host may not necessarily be tasty to his guest. Because people have different opinions about various ingredients and cooking methods. It is rather easy to misjudg e what someone considers to be the best dish. Forcing a guest to eat food he doesnt like is quite awkward. However, Western countries assert democracy, freedom, equality, and advocated personal power, put emphasis up on personal value, paysattention to individualism. We have to learn from the American literature that the theme of American Dream is an important indication in the American literature history. It means that Americans wish to succeed through their self-dependence and self-reliance. They believe that they are created by God and that they are endowed with special traits which will help them to become the kind of people they wish to be. So this culture connotation can also be reflected in the table cultures. They respect freedom. So there are not so many rules as in Chinese table setting. They behave freely. 4.2 The different way of thinking Compared with western thinking model, the eastern idea is blanket and unclearly. The Chinese thought is more comprehensive and integrated. Traditional perceptual intuition thinking including the doctrine of the thought in Chinese style. The essence of the idea emphasize harmonization or even cancel with extreme solution to the problem. The Chinese psychological bias for comprehensive, logical analysis. The simple integral concept and unified way of thinking reflects our national macro understanding and the ability to transform the world. The west emphasizes analysis and partial logic thinking, and emphasizes its own characteristics. For scientific thinking of the standard, this kind of thinking mode in the real world in present multidimensional nature. At the same time, in western countries, and always put the value of the individual in important position, the principle of the supremacy of outstanding individualism. 4.3 The different behaviors regulation Behaviors regulation means the single standard, which the society can accept. That means that something can tell people what is the right way to solve this matter and what is unsuitable to do. When different background culture people do communication with each other, they usually judge the rationality by own code of conduct. So it is inevitable for them to misunderstand others. And whats more, it will destroy the friendship between people. For example: In China, it is kind to pat childrens head, but it is a very terrible thing in the western country. They think it is unexpected thing to a child. If you do like this, his parents will get very angry for it. And the other different thing: In China, men always smoke after they finish the meals, they think it is a kind of enjoyment. Nevertheless, in western countries, they consider this behavior is not polite to women and children and it is also a rude thing to smoke on a table. So, it is very important for us to recognize and use the dif ferent regulation behavior when we do business or have communication between foreign countries. In order to ensure the communication will be smoothly, you should understand each others conduct. Especially remember the forbidden things and impolite things. The best way is when in Rome, do as the Romans. 4.4 The different values Value is the core of culture and the most appropriate criteria what is used to evaluate the behaviors, things and make choices from all possible targets by social members. Values are the reflection of peoples social existence, people in the same natural environment and social environment will have the same values. Therefore, every society and country is using their own recognized values. In the dinner table etiquette, peoples behavior is a microcosm of the national values and the corresponding behavior under the guidance of different values. In a state of ceremonies like China, emphasizes loyalty and filial piety, reflects the values of collectivism. Chinese people respect the aged and take good care of children, therefore, seating arrangements are very regular, seats not only have upper and lower grades, but also the specific seat sorting. For western countries, the individualism values occupy the dominant position and individual power of each person is reflected. This is because in the philosophy of Westerners, it tends to focus on individualism, personality development and self-expression. They think that if a person is not up to his purpose, which is not because of the destiny but their own laziness and their lack of fighting spirit. Western people put into practice individual dining system, each of them eat their own tableware and choose their own favorite food. So, in western, there will not appear the situation like eating the food reluctantly served by the hosts in China. Conclusion Different countries and different people have different manners. We should have a good knowledge about other customs so that they will not think us are ill-mannered. When exploring the differences in communication manners and customs, we set them mainly into three parts: manner and culture, communication manner and table manner. Considering the roots of these differences, Historical and regional causes might took the significant places. Therefore, a cross culture environment and a cross culture mind do lead to the better understanding in todays communication. In modern society, along with the development of the open policy, it seems that the world is getting smaller and smaller so that people are very active with frequent exchanges. With the constant deepening of integration of the world, we should pay more attention to etiquette among people. In particular, the importance of the table manners is more prominent. Consequently, we should admit these differences in cross-cultural commun ication, and understand and respect it as well. The key of successful intercultural communication is to have a correct attitude to deal with cultural differences. It is to understand and respect other countries culture that is the necessary condition to avoid cultural conflict, realize equal association and cooperate successfully. So as the graduate students, we must based on the requirement of the labor market. We will enter the society later, and before this we must get the full preparation of being a good worker. Only do we learn the different culture and practice it, we could find a good job quickly and do right things during the communication. By doing this can we make our work easier to be handled. If we can understand the manners better, we can know others better.

Character Traits of Elizabeth Proctor Essay -- essays research papers

Character Traits of Elizabeth Proctor   Ã‚  Ã‚  Ã‚  Ã‚  In the late sixteen hundreds, the fear of witchcraft was a major concern amongst New Englanders. Arthur Miller’s book, The Crucible, tells the story of a town’s obsession with accusing innocent people of witchcraft. All the accusers were young females who claimed they were attacked by demonic specters. Members of the community supposedly sent out these evil spirits, but in reality, the girls were doing it as sport. One such person accused was Elizabeth Proctor, wife of John Proctor, known throughout the community to be a noble woman. Throughout the book Elizabeth proves to be honest, untrusting of others, and determined.   Ã‚  Ã‚  Ã‚  Ã‚  Elizabeth’s honesty proves to be an important factor all through the book. This honest woman only lies once throughout the entire book. She tells this lie to Danforth in order to protect her husband’s reputation from being blackened in the village. Her honesty proves true when she is sent to jail for witchcraft, and she discovers she is pregnant. When she tells Danforth he says â€Å" There be no sign of it- we have examined her body† (92). In the last act, while talking to her husband, he asks â€Å"The child?† She then replies, â€Å"It grows† (134). This proves she was being honest while in jail. Another instance of her honesty is when she is charged with being a witch. Although the punishment was less severe for admitting to being a witch rather than claiming to be innoc...

Problems in implementing a self-regulation system: the case of a young advertising industry Essay

Advertising can be both beneficial and harmful to the consumers. However, in the perspective of kids, they might think that advertising is good, essentially when they get into contact with something that entices them. Honestly, advertising is bad for kids. The primary objective of the advertisers is to market their products for people to buy. Besides, if we are happy with the way things are, then we develop less interest to buy. This is the secret of the advertisers; they subtly try to make the consumers unhappy so that the chances of buying advertised goods get facilitated. The advertisers develop mechanisms to persuade the consumers to buy the products. In many occasions, most of what the advertisers are selling are images or a lifestyle rather than the product itself. Average Americans gets exposed to 3, 000 advertisement per day, thus, by the time of graduation in high school, and they will have watched 350, 000 television commercials. In the bulletins of the commercials, the con sumers still have to go through the photo-shop besides putting ton makes ups from the advertisers. Therefore, it is an illusion of their real appearance. Advertisement is done on television, radios, internet, billboards, cellphones and magazines. As Higgins, (2008) put it, advertising is a legalized lying. This is standing the truth because some of the products advertised provide different information to the real product. For advertisement targeting at boys, they develop the notion that violence is the answer to making fun among them. However, for girls, they show that dolls and makeup is their interest. According to ZÃŒÅ'abkar & JancÃŒÅ'icÃŒÅ', (2004) as a young girl sees advertisement for makeups, the information derived is to advise them to try the product and that provides comfort for them at young age. Advertising makes kids lose their creativity and imagination. Hence, the more they get exposed to advertisements, the more they develop an addiction and instead of creating time to play and socialize with peers, they rather get glued inside watching television which is unhealthy. According to research evidence, 16 percent of the ki d are overweight and need to play because they are inactive. Televisions continually brainwash many kids with advertising.Advertising is an important institution because it provides the required information and knowledge about the products and services. However, ethical standards in advertisement must be observed. Many ethical concerns have been raised by myriad stakeholders in the company of advertising. Ethics, mostly referred to as the domain of inquiry is a discipline in which matters of wrong and right, virtue and vice, good and evil are systematically examined. Advertisement ethics examines advertising morality and advertising systematically. Advertising of toys, none violent games and sugar loaded focuses on the children who are the highest consumers in the market. Besides, decisions on advertisement are about making morally right decisions. The morality of advertisement includes all parts of sourcing of product quality and pricing. Scholars have viewed ethical behaviour in d issimilar ways; however, it is based on the experiences and personal values (Taylor, 2008). Ethical advertisement forms the marketing strategies of the company. However, it all counts on the company objectives and what they know is expected by the consumers in the product. Theoretical Approach to Ethics in Advertising             The publication of the affluent society provided influential and important critique of advertising. It argues that businesses concentrate on generating rather than focusing on consumer satisfaction. The approach claims that the company system has assumed sufficient power and size to render the consumer on making personal decision such as what and how much is produced. Ideally, this characterizes the revised sequence-a categorical denial of the accepted sequence of the independence of the consumer, which accords the economic system power to the individual. Besides, the modern industrialized countries had an effectively planned economy ruled by large corporations with minimal respect to the interests of the public. Galbraith also observed the massive expenditures for creating a huge scale. Elsewhere, in 1958, Packard’ populist work titled the hidden persuaders brought moral concerns about consumer manipulation.Besides, Bentham on his personal argument would o ppose advertisement. The utilitarianism theory, however do not offer a clear-cut opposition for advertisement. He asserts that he greatest happiness of the greatest number gets determined by the consulting the hedonic calculus. Therefore, it is of fair reasoning that the advertisement is bad for the kids. However, he argues that if greater happiness is achieved through advertisement, then there is no harm. But the consequence is what counts. Based on the utilitarianism advertisement is harmful to kids due to its unhealthy consequences. On the other hand, Kant would declare in no certain terms are advertisement beneficial for the kids. What is wrong is wrong†¦period. The theory argues that it is wrong because it translates to dishonesty. Advertisement on kids is cheating them and treating the kids as end agent. As Kant puts it, this violates the categorical imperative (Kopf, 2009). Besides, the advertising consequences are irrelevant in determining the ethical or unethical of th e advertisements. Dishonesty is dishonesty and advertisement to kids is immoral. The duty of an individual is to tell the truth, to be honest in the information given.Mumel, Pisnik, Horvat & Makovec, (2013) explain the Rand theory by noting that he would oppose advertisement since it compost of dishonesty, however not on deontological grounds. Besides, dishonesty is harmful since it has dire consequences on the lives of the consumers especially the kids. Providing false information in the advertisement is dishonesty because it is a pretense that the product is not what is advertised. Besides, refusal by the industry system to perceive the facts I like shutting the eyes of the consumers to reality. According to the theory, advertising is unethical because advertising to kids operates to destroy and negates the objective and necessary reason for promoting the consumer’s lives. Dishonesty denies the consumers the efficacy to make individual decisions thus depends on other people’s opinions. According to Rawls, he would conclude that advertisement is unjust, period. Advertisement is harmful since it violates the principle of equal liberty of minimal economic and social inequality. Therefore, according to Rawls, it is ethical to raise a person from poverty to security than to provide the individual with an equal amount of wealth or societal well-being. Ethics, he argues, requires financial gain sacrifices in order to hold justice for the consumers who are least advantaged. According to his theoretical work, he insists that what is wrong is wrong. It is wrong due to its dishonesty. Conversely, the advertisement industry is cheating the kids with their advertisements. Conclusion             Advertising is widely bombarded by critics. Besides, it is accused of promoting consumption and materialism, using sex cell, stereotyping, of causing people to buy the product they need, manipulating consumer behaviour or of taking advantage of children and overall it contributes to the downfall of the social system. The advertisement critics abound. Since hardly a week can go without some company or advertisement or the advertising industry being focal point of controversy. Even if the consumer argues it out that they hold the sovereignty of the economy, the industry of advertisement does not provide an ethical justification of the traditional marketing theory. The emergence of ethical concerns in organizations is a complex phenomenon that incorporates social interaction and individual interpretation. Theorizing about ethics needs to reflect and match the complexity References Higgins, N. (August 20, 2008). Advertising ethics. New Scientist, 199, 2670.)Kopf, D. A. (2009).

An Exploratory Study on Consumer Decision-Making Behavior in Pakistan Essay

For example, the classical schools of marketing thought relied on the social sciences such as economics, sociology and anthropology and focused on aggregate market behavior. This gave way to the managerial schools of marketing thought in which the focus of attention and understanding shifted to the individual customers while social sciences disciplines continued to dominate marketing thinking. Customer behavior is actually a study of consumer buying behavior. Consumer buying behavior tells about why, how, when and where a consumer wants to purchase a product. It tells about the buyer decision making process. (Janssens, 2006) It enlightens the uniqueness of a single consumer, how he makes decision to satisfy his wants. What references he may use in this process, such as family, friends, reference groups, and society in general. (Archana, 2009) Patrick De Pelsmacker conseders that consumers have to impose products in respect to Psychological behavior and needs which further alienated in Perception, Learning, Attitude, Personality, and Lifestyle. (Patrick & J. 2007) Behavior of consumers in different part of Sahiwal city will be analyzed by using questionnaire method. This research will also give insight into Social influences regarding Family, Social class, Reference groups and Culture of consumers. (Brinkmann, 2004) This behavioral study will also enlighten on needs and wants in consumer buying behavior. The results will also show the consumers’ extent of loyalty, trust and satisfaction in retail brands that have a direct impact on their purchase decisions. (Constantine, E, ; Rigopoulou) Consumer behavior is an integral part of our daily lives. The psychological and social processes involved in buying and consuming goods and services form the subject matter of this text. The objective positivist approach to studying cause and effect in consumer behavior (as in any other kind of behavior), will be combined with the interpretive emphasis on trying to understand the emotional, non-rational aspects of the process. The environment which the consumer operates in, including the nature of the market place for goods and services, also needs to be considered. Behavior of consumers in different part of Sahiwal city will be analyzed. This research will also give insight into Social influences regarding Family, Social class. This behavioral study will also enlighten on needs and wants in consumer buying behavior. The results will also show the consumers’ extent of loyalty, trust and satisfaction in retail brands that have a direct impact on their purchase decisions. Data should be collected from the target market and then will be analyzed through SPSS software.

Malnutrition in Children Essay

Malnutrition in children is one of the most important social and health problem that face the young children in the modern world. Whether it is in the developed world or the under developed world, nutrition among the children has evolved to be a very important issue. Today’s children are faced with numerous physical, emotional, mental, spiritual and health challenges due to malnutrition. While a child in a poor neighborhood in Africa is sleeping hungry, a child in a middle class neighborhood in the United States is over indulging in unhealthy junk foods. Malnutrition is therefore an important social and health problem in all parts of the world. There is however a misconception that malnutrition in children only affects children in poor society where there is wide spread hanger, but this is no longer true. The over indulgence of unhealthy junk foods which are deficient in essential nutrients such as vitamin, poor living conditions, malabsorption and inadequate access to nutritional education and information on healthy eating are some of the many factors that force parents to make wrong choices in the quality of food they serve their children. Consequently, the number of children suffering from nutritional deficiency and related health complication such as obesity, poor growth and development and diseases has increased significantly. It is the role of the government through the relevant agencies and department to implement nutritional education through a national education strategy to ensure that the general public is well informed on the good eating habits as well as the consequences of malnutrition especially in young children (Dalton, 2005). Causes of Malnutrition in children Malnutrition is an important health problem in children due to its impacts on their growth and development. It is a condition that results from deficiency of essential nutrients such as vitamins, mineral salts and protein among others which are needed for the maintenance of health body functioning. Malnutrition can either occur as a result of under or over nourishment of a child with particular nutrients. Therefore majority of children suffer from malnutrition in the developed world today because of dietary imbalance rather than the deficiency of nutrient as it is common in the under developed world. Malnutrition can be caused by several factors which include poor diet and lack of adequate education on health eating habits. a) Diet One of the major causes of nutritional imbalance among children is the diet. Either parents influence their children directly or indirectly into improper selection of food or the modern society has over indulged in junk foods. Due to numerous promotions and advertisements in the mass media, children find fast foods more desirable. These may be snacked crisps, parked cakes and biscuit and other ready to eat meals. These fast foods have poor quality nutrients and ingredients which are manufactured to look special using large amount of fats and sugars, artificial preservative and additives which have negative effects on the individual’s health. There is no doubt that jack foods are processed food, ready to eat. These foods pass through the factories where the essential goodness of natural foods is removed and replaced with artificial additives and sweeteners. It is interesting to note that despite these fast foods having a long list of additives and preservatives on their labels in the name of ingredients, parents continues feeding their children in these foods. Moreover, many of the ingredients in junk foods such as fats, sugars, salts and additives are unhealthy to the children. The short term and long-term of such ingredients are well known. Junk foods are also deficient in essential dietary components such as fiber, minerals and vitamins which are very essential in growth and development in children. The dietary imbalance in children as a result of junk food is very event in the American society today (French, et al, 2001). It is important to note that one of the major causes of malnutrition in children is the choices of foods. Either knowingly or unknowingly, parents buy their children junk foods which are deficient in essential nutrients but have high level of unhealthy ingredients. There are several reasons that make individuals to make bad choices of foods. It is also important to note that the parent may not feed his children on junk food but end up preparing food that is unhealthy to the child due to bad choices. In many cases, especially in the underdeveloped world, parents may be forced by circumstances to make wrong choices for the foods they give their children. Poverty and food insecurity in some poor countries leaves parents with very limited choices of food resulting into malnutrition in children. Food prices in the developed world may also force poor parents to make wrong choices of foods. However, the most important factor that determines the food choice parent give to their children is the level of education and the nutritional information held by the parent (Hills, et al, 2007). b) Education Research indicates that many children are malnourished not because of unavailability of food and essential dietary components but because of the information held by parents and guardians. People who have the responsibility of providing their children with food have very little or no information on the quality of food they are expected to give their children. For example, the food and agricultural organization has argued that about 80 percent of malnourished individuals especially children live in areas around the world that have sufficient food supplies. Although poverty and food prices are also important factors, the level of information on implications of unhealthy eating habits is an important factor. In the American society, children are not malnourished because of inadequate food supplies but because of the choices of food. Children in America and other developed countries are increasingly becoming obese due uptake of unhealthy foods. There are no proper mechanisms of educating parents on health eating habits in children which as resulted into the society relying in misinformation from promotions and advertisements in the mass media. For example, inadequate breast feeding in infants is one of the major causes of nutritional imbalance in young children. Although there are many factors that contribute to poor breastfeeding such as changing lifestyles and job demands, lack of education on its importance on the health of the child id the most important factor (Hills, et al, 2007). Effects of Malnutrition in Children a) Obesity Over the years, obesity in children in the American society has reached epidemic levels. The percentage of children suffering from obesity in the American society has risen from below five percent in 1960s to over twenty percent today. Obesity has evolved from a condition that was in the past common among the rich families to a problem in the entire society. The number of children from poor families and middle class families suffering from obesity has increased significantly. Due to the increased prevalence of obesity among the young population, it has been rated as one of the most important health concern (Peter, 2005). The principle cause of obesity in children is unhealthy eating habits. Other factors may include genetic makeup, medical and psychological factors as well as lifestyles. The parents eating habits has been considered to be the biggest influence that play a significant role in the development of obesity in young people. Consequently, over weight parents have over weight children not because of genetic makeup but due to poor eating habits. Doctors have confirmed that the parents are not feeding their children with the right food which resulting into nutritional imbalance. The increased dependence on junk food as well as sedentary lifestyles adopted in the western world where children have not time for physical exercise has created a nation where a third of the children are over weight. This may be a time bomb since this creates a generation that will be faced with numerous health complications such as diabetes, high blood cholesterol and heart diseases (Dietz, 1998). b) Diseases Inadequate supply of essential dietary nutrients to the body in children is exhibited in various forms of diseases and disorders. It is important to note that the world health organization maintains that malnutrition and related complications is the most important health problem facing children in the world being the largest cause of child mortality globally, either directly or indirectly. Majority of malnutrition diseases are caused by lack or inadequate supply of essential nutrients. These diseases include marasmus, kwashiorkor, anemia and hyponatremia to mention but a few. Marasmus is caused by calories deficient, kwashiorkor by acute protein deficient, anemia by lack of iron and hyponatremia by lack of sodium. These deficient diseases are more common in the developing world due to widespread poverty and food insecurity. There are other numerous diseases that are caused by lack of essential vitamins and minerals. Other disorders that have been associated with poor eating habits includes eating disorders, anorexia nervosa and bulimia, stress disorders and depression, risk of drug abuse, high blood pressure, high blood cholesterol, type 2 diabetes and poor development of reproductive systems (Allen & Myers, 2006). Prevention of the malnutrition in children There is no doubt that malnutrition is both a national and international problem. Due to the large number of children with nutritional imbalance condition, the resultant health complication in the future may be overwhelming to the national health systems. It is therefore important for the relevant authority to implement the most appropriate educational programs that will educate the public especially parents on feeding children with health diets. Strategies that encourage adequate breastfeeding of infants and the dangers of unhealthy junk foods are recommended. Educating the parent to change their lifestyles and take responsibility of their children’s eating habit is also essential. Educating parents of obese children for example will assist them identify the root cause of the problem and design an intervention plan. It is also important for the parents to be aware of the nutritional need of their children which can be provided through civic education strategies (Hills, et al, 2007). The influence of the mass media in the modern world is not in doubt. Manufacturers of junk foods have bombarded the young people with advertisement which has had a significant influence on their eating habits. The same mass media can be used as a channel of educating the public on the importance of eating healthy foods. Media campaigns and advertisement that discourage unhealthy eating habits and educates people on dangers of malnutrition as well as nutritional requirement can possibly reverse the situation. However, these media promotions and advertisement should be carried out carefully to avoid magnifying the already developing social stigma against overweight members of the society. Promotion of physical education in school and encouraging children to involve themselves in physical exercises such as playing sport, walking a dog or riding a bicycle should be a top priority. There should be no excuse for physical education in schools while the parents should discourage passive activities at home such watching TV or playing computer games (French, et al, 2001). Conclusion Over indulgence in unhealthy junk foods rather that inadequate food supply is the most important form of malnutrition among American children today. These foods are deficient in essential dietary component and have high amounts of fats, sugars, salts, artificial additives and preservatives that have negative effects on children’s health. There is a need for the government through the relevant departments to implement policies and strategies that will save the children from malnutrition. This includes educating the parents on appropriate food for the children and promoting physical exercises among children. Strategies to combat numerous commercial advertisements of junk foods which make them look more attractive compared to healthy home made food should be developed and implemented. These policies should go hand in hand with ensuring increased access to quality and affordable foodstuffs. Reference Allen, R. E. & Myers, A . L (2006). â€Å"Nutrition in toddlers†.
