Are Turkish Dramas Evading Our Culture Essay

The foreign dramas are attacking our culture and these are not according to our culture After a contentious time of the Indian dramas, now numerous Turkish plays are giving rise to curious hype not only in our television drama industry but also in the minds of the general public. As a matter of fact, it is true that our local drama production is invoking the interests of thousands and millions of viewers and most of these spectators are finding these plays appealing enough to follow. However, in recent times it has been noticed that some foreign television content is trying to induce a substantial place in our country. Unfortunately, somehow a Turkish serial â€Å"ISHQ-E-Mamnoon† was aired out and after a few weeks it ended up by getting exultant high ratings. After the broadcast of this particular play, a slipstream is started among the different TV channels to get foreign content and present to the public, in order to gain high ratings. When broadcasters and people are basking this dubbed â€Å"so called† change, they forgot to think all this activity is turning out to be a veridical threat to the local industry as well as the integrity and culture of our nation. There is also a small group of people who is trying to back up these serials, but I think these people might disremember what Indian dramas have done with our acculturation in the recent past. Because of these plays, our adolescents (especially girls) have started out to follow their language. In fact, several words were became the part of their vocabulary and they used these words into their normal discussions. After ascertaining the severity of this issue our civil society and television industry have taken some measures and banned all the Indian channels. But now we have to cope with another scourge which is a lot more dangerous than the previous one. We need to observe what sort of message these Turkish dramas are trying to convey? Are the stories of these plays fair enough to watch with our parents, brothers and sisters? Of course not and that is the main reason why it is considered as infectious to our culture and nation by our producers, writers, actors, directors and now public as well. These Turkish serials are full of bold scenes, which is totally against our moral values and they are just becoming the cause of raising the level of grossness and vulgarity. All in all, our music and film industry is neither cohesive nor strong. This is only the television industry that is producing high caliber dramas and bringing out the talent nd acting of impeccable quality and it should not have to endure the same issues as our film and music industry are confronting. Apart from our cultural and moral values, these Turkish serials are also threatening the future of thousands of actors, directors, cameramen, writers, producers, spot boys and other individuals who are directly or indirectly associated with our local drama industry. Although, a good and positive aspect is that our actors are united and they are unitedly saying the Turkish or any other foreign content should not hijack the viewership of our local dramas. If we take a close look at the history of subcontinent then it is not very hard to find the same interference of the popular East India Company that eventually became the main reason of Subcontinent’s separation. However, right now things are quite under control and still it is too long to anticipate any resemblance with this specific issue. Although our government must have to take impertinent and smart actions in order to avoid the drastic effects on our culture as well as on economy which is depending on our drama and entertainment industry.

Pagan Christianity by Frank Viola Essay

The book â€Å"Pagan Christianity† by Frank Viola and George Barna leads readers into the world of religion, religious customs and rituals, sermons and religious clothing. The authors show how the church has changed over times and what new practices and beliefs it has adapted. Frank Viola is known to be an American writers and speaker who has published a series of books devoted to problems with church calling people to return to the biblical principles. Therefore, the central thesis of the book is that people should get back to biblical principles in their religious beliefs because modern church practices are rooted in secular or Pagan practices which have nothing to do with the Bible and God’s commandments, as well as the church doesn’t resemble the early church which was described in the book of Acts. Modern church is based on hierarchical structure; whereas the author claims Jesus came with the strong intent to put an end to legalism, structure and hierarchy. The book is very interesting from historical viewpoint and I think that it is broadly accurate offering us new insights and facts from religious past. Pagan Christianity The authors start their narration with strong claim that modern churches have little resemblance with the early centuries churches described in the New Testament. With the partaking of the Traditional Church the author became very interested trying to reveal what we went on. The first chapter is reflection of authors’ inquiries on the subject of interest. For example, Viola questions whether there was a need to turn down light and to wait when the Spirit would move on to another church. The author thinks we are the ‘Children of Lights’, although he admits that he doesn’t agree with any theologian and preacher offering his unbiased review. It is said that the word ‘pagan’ is a part of book’s title and it is applied to the churches being discussed. However, even the authors agree that often this term is not applicable. In the second chapter the author discusses the issue of the Church Building and ‘modern’ church-goerselievers. It is emphasized that the Church has built itself. The original meaning of the word refers to the Greek language ‘ekklesia’ and it means a group assembled. Viola argues that time and words are describing the gradual development of Holy Places and things which are considered important parts of religious world. The authors discuss Constantine as he was one of the first Christians who gave legitimacy to the Christian Religion. Constantine promoted and supported grand displays of religious architecture. Further, the authors review religious clothing, music, steeples, architecture, thrones borrowed from other cultures along with customs and rituals. In the third chapter Viola provides overview of the order of traditional Worship and description of Sunday morning sets. He argues that standard order should be held in all churches with only slight differences. For example, he writes: â€Å"You can scour your Bible from beginning to end, and you will never find anything that remotely resembles our order of worship†. Further, the authors describe contributions of historical Church leaders – Luther, the Puritans, the Pentecostals, etc. In the fourth chapter they describe the sermon abandoning principles of Protestantism. The authors argue that the early churches were not the sermons; instead, they were places for gathering and Jesus functioned as its Head. In the fifth chapter Viola and Barna introduce the Pastor which is viewed as an obstacle to functioning of every member. The pastor is the fundamental figure in Protestantism and he â€Å"is often better known, more highly raised, and more heavily relied on than Jesus Christ Himself†. (p. 65) And it is a serious mistake. It is noted that the word ‘pastor’ isn’t a tile – instead, it is a function. Viola notes that the word ‘pastor’ is referred to in Ephesians 4:11 only one time: â€Å"a scanty piece of evidence on which to hang the Protestant Faith. In this regard there seems to be more biblical authority for snake handling than there is for the present-day pastor†. p. 66) In the sixth chapter there is a detailed description of Sunday morning costumes. The authors describe dressing up for church, what clothing is appropriated and why. The next chapter is devoted to the origins of Music Ministry and description of the hierarchy of clergy. The eighth chapter analyzes Tithing stressing that it is used in the New Testament and Clergy Compensation, althou gh it is never used by the Christians. Further, the authors specify Baptism, its core principles and fundamentals. They explain that Baptism has replaced the Sinner’s Prayer. The Lord’s Supper was firstly a festive banquet and, therefore, lost its concrete picture of ‘The Body and Blood’. The final chapters are devoted to religious education and how it is possible to receive the qualification to Minister the gospel. Viola and Barna provide new insight into the New Testament offering so-called second glance at Jesus, churches, pastor functioning, religious customs and education. Conclusion: Strengths & Weaknesses Frank Viola and Geroge Barna offer new ideas and facts about religious order, customs, traditional music and dressing. The book is very informative, innovative and well-organized. Moreover, it is very interesting from historical perspective as it is challenging and thought-provoking. The authors incorporate many references about the culture of time, adaptation of church, etc. I like their idea about church building that church is not the place – it is the people. Nevertheless, there were several controversial moments I can’t agree with. I see that Viola offers his own version of organized empire and it seems that he is supreme speaker and the founder of knowledge. It is evidence of hierarchy which he manages to escape. Moreover, he claims that such situation shouldn’t happen in church, although he puts himself on superior position. Viola calls people to leave their church as all of them don’t follow Biblical principles. However, he tells we are the Body of Christ contradicting himself. I think that we shouldn’t worry about such doctrinal issues. Despite certain weaknesses, the book is very informative and fresh.

Performance Management Term Paper Example | Topics and Well Written Essays - 2750 words

Performance Management - Term Paper Example The basic similarity between all the three books is that all of them provide practical examples and implications of the studies carried out in the workplaces. However, discussing the differences, the book, â€Å"Motivating Human Service Staff† written by Reid and Parsons the focus is on increasing motivation through supervisory control where authors have the view that employees should be made to work hard, but at the same time, they should enjoy their work because they are either given good incentives or are acknowledged, recognized and praised for performing well. In this regard, Reid & Parsons provided an example stating that in service industries most of the employees are seen having low morale or reduced levels of motivation, the reason being that the nature of such industries lacks clear incentives. Moreover, it is seen that even the workforce itself carries such de-motivating traits because either their organizational structure is autocratic, or they may not have a histo ry to work in the same profession before. Thus, as per the authors, during these situations, motivation becomes the responsibility of the management, and it is necessary for them to identify ways to support diligent workforce.Such examples given in the book show that Reid and Parson feel that the changes in behavior, as well as, skills can be carried if the employees are given a clear set of goals to accomplish along with key drivers that provide support for them to accomplish their goals.

Immunization vs incidence of Autism Essay Example | Topics and Well Written Essays - 2000 words

Immunization vs incidence of Autism - Essay Example Immunization is one of the factors that have been implicated in the incidence of autism. Since 1999 there has been a controversy about whether thimerosal–containing vaccines contribute to the causes of Autism Spectrum Disorders (ASDs) and neuro-developmental disorders (NDDs) in children. Autism affects not only the children living with the condition but the families of these children. Some siblings have to learn how to cope with a brother or sister who is autistic. It is of great importance to parents and has caused many parents to question the safety of immunizing their children. Several parents have refrained from immunizing their children against common childhood diseases. This has caused conflicts in schools where immunization is a requirement of a young child entering school. It is important therefore to understand as much as we can about this disorder and whether there is in fact a connection between vaccination and the disorder. The purpose of this paper is to explore the relationship between the Autism Spectrum Disorder spectrum and immunization. The paper seeks to review the research evidence provided on both sides of the debate. Does the immunization of a child in fact increase the possibility of developing autism or is there no relationship between the chemicals in childhood immunizations, e.g. thimerosal and autism? It is important to try to determine how valid and reliable the research studies are. Parents need to be reliably informed about the consequences and possible dangers of immunizing their children. The analysis of the topic could help them in their decision about whether to immunize or not. An initial examination of the topic could help in the weighing up of the pros and cons of immunization against the possibility of the child being vulnerable to developing the autism disorder or any other neuro-developmental disorder. It

Central bank independence and economic performance Assignment

Central bank independence and economic performance - Assignment Example For instance under the floating exchange rate regime, protecting the value of the domestic currency against US Dollar and other international currencies calls for vigilance and continuous monitoring of the world economy through various economic indices. Regulating money supply and interest rates are governed by several domestic and international factors as well. Therefore, independence of the central bank is necessary to deal with these problems effectively without any interference in the regulatory process. However, the level of independence varies from country to country based on the political and economic system prevailing in the countries. Long ago in 1929 Montagu Norman, Governor of the Bank of England wrote: â€Å"I look upon the Bank as having the unique right to offer advice and to press such advice even to the point of nagging: but always, of course, subject to the supreme authority of the government† (Toniolo, G. 1988 p. 47). This statement underlines the need for in dependence as well as its limitation. The role of central bank Central bank’s monetary policies have different impact on different economic variables of the economy. Increase in money supply with or without decrease in interest rates could trigger inflation in the economy. Therefore, careful analysis of the economic indicators is important in taking appropriate action by the central bank. For instance, inflation in this case could affect consumption thereby demand for the products. At the same time, this could increase capital investment and results in employment generation. Stability in exchange rate is another important factor which could affect inflation in the country and foreign direct investments in the country which will have...This paper offers a comprehensive analysis of the role of central bank in terms of economic performance of the nation. Influence of the political independence of central bank operations in context of achieving its objectives is under review. In order to achieve economic growth in a country, formation of capital is essential for fresh investments in the economy. Increase in aggregate demand in the country is an important factor in this regard for attracting investment of capital in new projects. Liquidity in the system as well as interest rates should be monitored and regulated on a continuous basis by the central bank to provide good environment for capital investment and consumption which in turn will generate demand for the products. However, the central bank should also ensure that it does not result in overheating of the economy. Regulating interests and money supply in the economic system is very complicated in the backdrop of technological developments taking place in the world and globalisation of economies. The independence of the central bank of the county is very important for exercising control over the commercial banks in the country through its monetary policies. The monetary policies need to be complementary to the fiscal policies of the government to achieve its economic objectives. A country with high central bank interference need to introduce reforms to make the institution more independent within the timeframe set for this purpose to improve stability in liquidity and prices.

Benner's Competency - Assignment Example tal health is a significant of the general wellbeing of an individual and hence I engaged the patient to regain normality through constant support on all aspects of the day to day activities and counselling to alleviate depression that was overwhelming to the patient thereby diminishing the chances of recovery (Benner, 2000). The patient attempted to commit suicide twice while undergoing mental rehabilitation. I understood and responded to the patient’s reactions to distress that came as a result of hopelessness and anxiety. I managed to guide the patient through behavioural and emotional changes that were occurring in his mind while recognizing and promoting effective participation in the day to day activities to help him understand and live to his full potential. According to Masters (2011), a nurse needs to promote a feeling of resiliency which is critical to a mental patient’s recovery. I helped the patient to re-gain self-esteem and confidence through inspire hope and power in him, which positively influenced his behaviour after realizing that his contribution is necessary to the development of his community. I coordinated with his family that provided useful historical information on the patient’s previous engagements, which helped me to make out the impact of culture and tradi tions on the healing process. I was able to evaluate and explain the effect of the patient’s beliefs, principles as well as life engagements on the condition. I shared this information with the physician in charge and other colleagues and together we were able to develop care strategies that were culturally welcome thereby enhancing the recovery process. Communication skills were significant in dealing with the patient. Listening carefully to his incoherent speech helped me to make sense out of it and also understand him better. I also observed his behaviour keenly and tried to relate it to past experiences with similar patients that I had come across before, which helped me

The roles of pubic relations in crisis managment Essay

The roles of pubic relations in crisis managment - Essay Example The aim of nurturing public relations is to develop rapport with the public and by making them understand the organization and what its doing (Felea, 2004). Experts in public relation use all typology of communication with the public, as represented by personalities who are imbued with institutional and organizational identity (Felea, 2004). This process is deemed significant to avoid or wane down the opposition of employer and employees, in case of labor dispute, or probably to reduce panic in the market in the case of financial crisis. In international relations, countries diplomatically develop public relations to ensure that social acceptability and to maintain social peace while engendering cooperation and collaboration on social policy or agenda (Felea, 2004). This is also true in market relations to ascertain efficiency on commercial firm’s services and to maintain connections with its clients while on business operation (Felea, 2004). Thus, in commerce, a company would use advertisements and other related propaganda to better its relations with the public, its â€Å"goods suppliers, services providers, labour suppliers, clients, competitors, public organisms (Felea, 2004, p. 1).† Media is an instrument or tool for public relations. Companies relate with media to promote their products and to explicate its business operation and its campaign or probably to promote their activities relating to corporate social responsibility. With globalization taking the market’s core, modern commerce necessitates media in social networking, including the explication of its definitional struggle in the interface of science and policy for the market. David (1999) for instance explicates the significant effort done my farming industry in explaining to the public cattle disease bovine spongiform encephalopathy (BSE) or mad cow. By doing so, the company is able

Frictions between Parents and Children Essay Example for Free

Frictions between Parents and Children Essay Family is an essential part of every person’s life and of our society. Family is a little world with its own values and priorities. Close families share dreams, ideas, hopes and even possessions, and it’s a good side of being a family. However, as usual, every good thing can have its drawbacks. Same with families: they can often have different types of problems. One of the most frequent and common problems is the misunderstanding between parents and children, due to the difference of generations. This problem is especially acute with teenagers, who want to have more freedom, to express their self-identity in a way they want to. Honour your mother and father and you will live long and be well, if not, you will die — says the Bible. Some families are happy, some are dead. It seems to me the reason is misunderstanding of each other in the family. One more thing, teenagers can take on most of the rights and responsibilities of adulthood. Before this occurs, however, they go through the period of adolescence and most of them experience conflicts at that time. They change rapidly both physically and emotionally and they search self-identity as they grow up and become more independent. Sometimes teenagers develop interests and values different from those of their parents. That sets a conflict between two generations, which leads to a gap in mutual understanding. Traditional disagreements are: the time to come home at night, doing work about the house and the friends to spend time with. Id like to point out, that teens face a number of problems: drinking alcohol or using drugs. Moreover, some children run away from their homes. Most of them return after a few days or weeks, but some turn to crime and become juvenile delinquents. Im convinced that sometimes parents do not care about their children. It is exactly at that age when young people need a piece of advice or help. Parents should help their children and find the right approach to them so as to make everything clear. Being able to view the problems more rationally, they should try to do their best to resolve them. We need to learn to talk our problems over in our family. If we are able to do it, everything will be all right.

Pectin Reduces Blood Cholesterol Level

Pectin Reduces Blood Cholesterol Level Xinhao DAI Introduction Pectin is a complex polysaccharide present in plant cell walls, commonly presents in fruits and vegetables, commercially extracted from pulp waster during fruits juice processing. Pectin can be used as gelling agent in jams, marmalades and reduced sugar versions. It creates thickened textures and a homogenous distribution of fruit pieces. The consumption of pectin by human influences transit rate, nutrient absorption rate, and cholesterol absorption and secretion, so pectin is an important dietary fiber. However, the clinical use of pectin is very rarely mentioned (F Brouns, 2012). The degree of esterification (DE) demonstrates the methyl esters in pectin chains. The pectin with DE>50% are high-methoxyl and forms viscous gels in the stomach at pH 2.2-3.5 (Ralet et al., 1994; Sila et al., 2009); the pectin with DE60%) at low pH; low-methoxyl pectin forms gels with divalent cations (notably Ca 2+) at pH 2.5-6 (sugar addition not required) (Thibault and Ralet, 2008). Cholesterol is an important biological molecule, which function as component of cell membrane structure as well as a precursor for the synthesis of the steroid hormones and bile acids. High concentration of cholesterol in human blood is related with coronary vascular disease, atherosis, stroke and many other diseases. European Food Safety Authority (EFSA) (ESFA, 2010) has published the cholesterol lowing effects of of pectin on glycemia. In general, processing factors like DE, MW, and pectin source (e.g. citrus or apple) may affect the efficacy of pectin (Baker, 1997; Duvetter et al., 2009). Cholesterol lowering in animals Pectin has been reported being able to lower the cholesterol level of blood and liver in various animals, including guinea pigs (Gorinstein et al., 2005), rats (Krzysik et al., 2011), hamsters (Terpstra et al., 2002), chickens (Craig et al., 2006) and rabbits (Ismail et al., 1999). The effect of lowing cholesterol level by nine types of pectin with different molecular composition on 486 male broilers was studies, their serum cholesterol lowing efficacy was ranked as: citrus pectin DE-70 1⠁„4 apple pectin DE-74apple pectin DE-354citrus pectin DE-04low-MW pectin4citrus pectin DE-354cellulose (Craig et al., 2006). The mechanisms of cholesterol lowering in animals mostly are increasing fecal bile acid excretion, reduced plasma triacylglycerol, plasma total cholesterol, hepatic triacylglycerol, cholesterol synthesis and absorption, et al. Some of the mechanisms may be related with humans (F Brouns, 2012). The result of experiments feeding Wistar rats with semipurified diet with psyllium or pectin, cellulose or rice bran supported the hypothesis that the hypocholesterolemic effect of soluble fibers is functioning by increasing synthesis and therefore pool size of bile acids (Hugh B. Matheson, 1995). Another study showed that the hydrophobic amidated pectins significantly modify cholesterol homeostasis in rants and might provide insight of an effective hypochelosterolemic agent. However, the amidation of pectin might reduce its fermentability (M. MAROUNEK, 2007). Overall, pectin influence animal blood cholesterol by affecting cholesterol homeostasis. Cholesterol lowering in humans There are not many clinical studies of pectin cholesterol lowing compared with animal studies. Generally, each gram of pectin lowers LDL cholesterol (LDL-C) by 0.055mmol/L (Brown et al., 1999). A cause-and-effect relationship has been established with 6g pectin in ≠¥ 1 servings for maintenance of normal blood cholesterol concentration (ESFA, 2010). The table 1 summarized the most important studies of pectin lowering cholesterol level before 1988 (Kay Behall, 1986) (Cerda, 1988) Table 1. Pectin Lowering Cholesterol Level Studies Before 1988 A recent crossover study involves hyper-cholesterolemic persons receiving either 15g/day pectin (from citrus or apple, with different DE level) or cellulose with food for 4 weeks. The result showed that (F Brouns, 2012): For relative low-density lipoprotein (LDL) cholesterol (LDL-C), the effect of citrus pectin and apple pectin are the same, while the pectin with higher level of DE level has better hypocholesterolemic effect. Orange pump fiber worked worse than citrus and apple pectin. The pectin with higher molecular weight works better than the pectin with low molecular weight. In the subsequent experiment providing 6g pectin/day for three weeks, citrus DE-70 and high MW pectin DE-70 reduced LDL-C 6-7% compared with control group. The viscous, gelatinizing citrus pectin alter bile acid enterohepatic circulation; enhance cholesterol excretion into stool (Martinez de Prado et al., 1981; Ide and Horii, 1989; Ide et al., 1990; Fernandez et al., 1994; Terpstra et al., 2002). High-viscosity pectin generally diminishes total cholesterol (TC) by 3-7% in humans. Pectin increases gut viscosity, then reduce the re-absorption of bile acids, increase synthesis of bile acids from cholesterol, thereby reduces circulating blood cholesterol (F Brouns, 2012). The high-viscosity pectin might also interfere with the formation of micelles and/or lower the diffusion rate of bile acid and cholesterol-containing micelles through the bolus, consequently reduce the uptake of cholesterol and bile acids. Many study suggested the favourable effect of pectin on lipids(B.R. Sharma, 2006). The source and type of pectin (degree of esterification and molecular weight) affect the effect of lowing cholesterol. In the study by Brouns et al., it is proven that increased DE and MW help promote the efficacy of lowering of human cholesterol level, and even a high dose of pectin with low DE and MW won’t have significant effect. The EFSA pectin cholesterol-lowering claim should require a minimum level of characterization, including DE and MW (F Brouns, 2012). Even though pectin cannot be directly absorbed by human, it can be fermented by the microorganisms in the large intestine and result in the formation of short chain fatty acid, which could be absorbed and metabolized in the colonic mucosa, liver or peripheral tissue (Kay, 1982). Effective doses Experiments indicate that the dose of pectin needed for different people to achieve the lowering of serum cholesterol level is not the same (Grant H. Palmer, June 1966). The intake of 15 grams of pectin per day for three weeks resulted in a mean 13% diminishment of plasma cholesterol levels. A dose of 40 to 50 grams of pectin per day significantly reduced the cholesterol level in both normolipidemic and hyperlipidemic subjects(B.R. Sharma, 2006). In addition with the claim of consume 6g/day pectin to achieve hypochelosterolemic effect, ESFA (2010) also suggest that the consumption of pectin with meals help reduce the blood glucose after meal and the effect can be achieved with at least 10g pectin per meal ((EFSA), 2011). The hypocholesterolemic effect of pectin combined with apple polyphenols has also been reported (EVA N. JENSEN and DRAGSTED, 2009). There might be taste concerns and potential gastrointestinal disturbance if more than 6g pectin/day was ingested (F Brouns, 2012). At least 6 grams of pectin are supposed to be consumed to achieve hypochelesterolemic effect, and this amount is correspond to 7~8 medium-sized apples (EVA N. JENSEN and DRAGSTED, 2009). Some critique suggested that most of the cholesterol lowering effect of pectin is showed in a cholesterol rich, atherogenic diet (A.H.M. Terpstra, 2002). The effect of cholesterol lowing efficiency in regular diet remained quite questionable. Conclusion Viscous pectin can reduce the cholesterol level of animals and human by increasing synthesis and excretion of bile acid and reducing re-absorption of cholesterol. The hypochelosterolemic effect of pectin depends on the dose of pectin, diet composition, and source and physical and chemical property of pectin itself (including viscosity, molecular weight, and degrees of esterification). The effective daily intake of pectin is at least 6g/per according to EFSA, however a minimum level of characterization should be required to achieve the result.

Hans Kelsen, The Pure Theory of Law Critique

Hans Kelsen, The Pure Theory of Law Critique Essay Title Hans Kelsen, The Pure Theory of Law its Method and Fundamental Concepts (1934) 4 Law Quarterly Review, 474 Critique Word Count 2000 words The Austrian philosopher and jurist named Han Kelsen proposed the Pure Theory of Law. According to Kelsen, the standard legal philosophies were marred with contamination of law with moral and political ideology, which was compounded by attempts to marry law with social sciences. Hence, both of these endeavours were an exercise in futility as they were riddled with flaws[1]. Thus, Kelsen proposed the Pure Theory of Law, which would avert attempts of reductionism of any form. It simply accommodates pure law in itself as it is founded on primary methodological principle. Given that the law is to be perceived as a normative/ standard practice, the usage of methodological reduction needs to be averted altogether. Reductionism was needed to be averted at all costs since law is needed to be divorced from nature and morality[2]. As per Kelsen, law is a system of norms. According to him, legal norms are devised by willed acts or in other case, the products of deliberate human action, contrary to moral norms dictated by God. Thus, the pure theory of law undertakes only human-based norms, as opposed to imaginary superhuman entities[3]. 1. The Theory of Positive Law The Pure Theory of Law is termed as theory of positive law. Hence, the theory is more so given in terms of formation of hierarchical laws commencing from basic norm. The remainder of the norms are associated by inferior norms, when one is contrasted with another[4]. 2. Laws and Morals The segregation of morals and law by Kelsen forms an essential component of theory of pure law. By its standards, the law needs to be divorced from political and moral influences. Hence, the law should be in its clear form, unaffected by moral and political undercurrents[5]. 3. Science and Law According to Kelsen, the law was described in form of implementation of norms to state machinery. As science was primarily based on comprehension of epistemological data, therefore, its causal and logical technique was to be differentiated from normative reasoning as given in pure theory of law[6]. 4. Static Nature of Law The static theory of law was differentiated from dynamic theory of law. However, this static theory of law presents law in terms of hierarchal laws where laws are deemed as inferior to one another[7]. 5. Dynamic Nature of Law In case of dynamic nature of law, the static theory of law comes toe-to-toe with governmental administration of a given state, which needs to acknowledge the function of legislature in penning of the new law. Simultaneously, an understanding of law being impacted by net standing law which encompasses the court-related decisions are enfolded in the hierarchical representation of pure theory of law. Hence, Kelsen allows legislative machinery to note law as a product of the ethical and political process[8]. 6. The Normativity of Law The normativity of law can be paralleled with that of religion, as it does not base on the inherent obedience of the concerned subjects. For instance, the norms of Christians would be held in validation even in the absence of Christians. However, it is hardly the case with law. The key implementation of law/ legal system banks on its actual practice. The legal order is defined by norms which are by and large effective. The element of basic norm rests on its effectiveness. As asserted by Kelsen, the successful revolution results in an eventual change in the nature of basic norm[9]. 7. The Basic Norm As per Kelsen, the law is an arrangement of norms. These norms are should be statements, setting up certain forms of conduct. Contrary to moral norms, as per Kelsen, the legal norms are set up by the legal norms creation of willed acts. It is a product of human action. Hence, Kelsen thoroughly supposed that law which entails ought and should be statements, is unable to be reduced to such natural actions/ events which gives impetus to it. As a result, legal norms are ought/ should be statements, since it is unable to be deduced simply from factual premises[10]. As per the claims of Kelsen, the law is simply the hierarchy of legal norms at different levels as opposed to being a system of coordinated norms of equalized level. When the legal norms are far from positive/ just, then legal order becomes problematic. As per Kelsen, no such norm exists which is predominantly unchallengeable. No such grand norm exists, since it is purely arbitrary in nature. This norm essentially came from competence, collective will and capacity of individuals. Thence, Kelsen has deployed this term in order to dictate the basic norm, which forms the pillar of the legal system. Hans reasoned that a need for pinpointing the origin of law is necessary in order to gain its legitimacy[11]. A pure proper law often differentiates the ought statement from is-statement. In case of is statement, when something is done/ not done is an indicator of action. In case of ought statement, when something is done/ not is an indicator of a greater form of reason needed for action. It involves obligation and discharge[12]. Hence, the key objective and motive of Hans Kelsen was to safeguard the sanctity of law from two major zones of methodological syncretism which a legal system often entails; sociology and psychology as well as politics and ethics on the other side. Law is to be deemed as a normative order. Kelsen has indicated that a key relation exists between validity and norms, however, he asserts that both are all the more dissimilar. An ineffective norm may lose its validity, similar to the legal order should have a key linkage to effectiveness, a key point postulated by Kelsen in discussing the basic norm[13]. According to Pure Theory of Law, positive law is defined as a valid order which is held only when the condition of basic norm is supposed. Thence, the theory characterizes this meaning as a possibility as opposed to being necessary. Hence, it becomes only as conditional when it is presupposed basic norm[14]. According to the categorical differentiation of ought and is, ought is unable to be reduced to is, and ought is unable to be an is. Thus, is is unable to be inferred from that ought, neither vice versa. The dual nature of ought and is does correlate with that of value and reality. Hence, no value could be can be obtained from reality, as well as vice versa.The next layer, that of rules, is the realm of Ought. It is visualized vertically. According to Kelsen, it deals with the legal meaning, namely, a specific legal significance. The Ought comes up to the actual substrate, the Is. Legal acts of the laws, judgments, the private law, e.g. private contracts, etc. constitute the Ought as a regulative background of the Is stage[15]. Hence, ought is related to imputation and is is connected with causality. The weight is on a vertical plane, whereas the is on a horizontal plane. The Pure Theory of Law exists on a metal-level and intends to attain cognition[16]. The strength of Pure Theory of Law lies in the provision of a theoretical law, which accommodates administrative and judicial tribunals along with legislative rigours of the legal system and administrative bodies. Pure Theory of Law confers power to subordinate administrators in order to devise a subordinate legal norm, and to indicate the nature of such norms. The Pure Theory of Law is devised for traceability of each legal act to be in line with the penned constitution[17]. It could be perceived as a handy analysis tool for assessment of numerous constitutions. Another advantage of this theory is that it presents an active legal order as opposed to a static one. Hence, the law remains orderly via maintaining fluency along most of its components, by simplifying and broadening the principles of law. It acts as a form of logical system. It could be theorised as a complete, proper logical system. The theory of Hans Kelsen is typical of all key law theories, which stringently emphasises the need of orderliness in law. It stresses highly on the value of law. However, it supports a new form of orderliness diverse from those given in judicial precedents[18]. The Pure Theory of Law has considerable flaws as examined in this section. It essentially precludes the elements of sociological justice and morality, which paves way for efficiency. This form of theory is unable to be applied to each legal system since each legal system operates with its own norms and rules. A man-made theory is unable to adjudicate the legal repercussions of a sudden change. The Pure Theory of Law posited by Kelsenian theory is largely criticized since conceptual and abstract theory is unable to accommodate the validity of standard laws encompassing the legal system[19]. Each particular legal system sets its own rules and boundaries founded on their validity. The theory seems steeped in fiction as it is largely applicable on fictitious situations and it has no particular grounds for acceptance in reality. No such theory can be applied to a legal system since each possesses its own hierarchical order and norms. Conflicts arises in case of multiple legal systems. Due to its excessively narrowed scope, it is unable to accommodate altering circumstances and conditions posited by the law. The theory is invalidated on revolutionary grounds, however, no particular effectiveness criterion is set up either[20]. Since, Hans has compared the purity and objectivity of his posited theory with ideological and political propensities of his previous theories, it merely turns out to be a mere inadequate reflection on his previous assertions. It is necessary to reflect on personal consideration and prejudices prior to positing an individual world-view. Therefore, it can be reasonably assumed that theory of Kelsen is far from political and ideological purity. Hans Kelsen remains unsure of the norm to be established and its source of emergence. At times, he seems to posit that this norm will emerge from the constitution, in other cases, he hangs by a legal shoestring and sometimes by the laws presented by a dictator. Thus, his supposed norm remains ambiguous. As the legal system is founded on moral principles, it is guided and steeped in morality. The divorce of morality from law is essentially legal suicide. His theory is unable to validate moral law since each present law accommodates morality in it s confines[21]. References   Bulygin, E. An Antimony in Kelsens Pure Theory of Law.

Privacy Risks of Internet Wiretapping      Ã‚  Ã‚   Abstract: In recent months, the FBI has taken steps to implement an Internet wiretapping scheme called Carnivore.   This paper discusses the possible risks of this system with respect to personal privacy, analyzes the technical flaws of the system that produce these risks, and discusses recent US Legislation to relax the statutory restrictions on its deployment and use.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   On September 11, 2001, a group of terrorists carried out a methodically planned and almost perfectly executed attack on major sites in the United States, toppling two of the nation's highest buildings.   Two days later, on September 13, the US Senate unanimously approved legislation that may serve to topple one of its greatest freedoms: the right to privacy.   This legislation, which its drafters Orrin Hatch (R-UT) and Dianne Feinstein (D-CA) dubbed the "Combating Terrorism Act of 2001," would loosen restrictions on FBI wiretaps, including its nascent "Carnivore" Internet surveillance system [1].   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Carnivore is a system introduced by the FBI to provide it with "a 'surgical' ability to intercept and collect the communications which are the subject of a lawful order while ignoring those communications which [it is] not authorized to intercept" [2].   It works in a manner similar to a network packet sniffer, which intercepts and copies all bits of information that pass through a network.   It differs from a normal packet sniffer, however, in that it is designed to distinguish from the noise those bits of information which apply to a specific court order [2].     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There is nothing new about the FBI conducting surveillance; what disinguishes Carnivore from past methods of surveillance... ...Answers."   http://www.pbs.org/cringely/pulpit/pulpit20000713.html, 13 July 2000. 4.

A New Genus of Hominins Found in Kenya :: Anthropology Essays Paleontology Papers

A New Genus of Hominins Found in Kenya Whenever finding new fossils, most people get excited in learning more about the mysterious history of life on earth. No one fossil finding may be more important than another, but when discovering a fossil that adds a new genus name to a species, it gets exciting. This is especially true when the fossil gives more insight to the evolution of humans. In Kenya, a new genus of hominins was found. The new genus was assigned because this hominin had a combination of derived facial and primitive neurocranial features. This hominin is guessed to be about 3.5 million years old. The findings lead the scientists to an early diet-driven adaptive radiation, which gives insight on the craniodental features, or the structure of the skull and mouth. The name of the species is Kentanthropus platyops (the Flat-Faced Man of Kenya). This fossil was found in a rugged desert-like site on the western shore of a lake in northern Kenya. This is by the Topernawi river drainages in Turkana district in northern Kenya. This fossil is known to be twice as old as Lucy, a famous Australopithecus afarensis, which is only about 1.8 million years old itself. The age of this fossil has been established because it was found in between layers of different aged soil. Eight meters below the Tulu Bor Tuff and 12 meters about the Lokochot Tuff is about 3.5 million years old, this is an area called Kataboi Member where the type of specimen is found. The paratype is from lower Lomekwi Member, seventenn meters above the Tulu Bor Tuff, estimating at 3.3 million years old. Kentanthropus platyops is estimated to be about 3.5 million years old itself. The age can also be estimated aroun 3.5 million years because hominin findings from Lomekwi, two mandibles and isolated molars have previously been found, which indicate the time period. The skull was found amongst a temporal bone that was well-preserved, two partial maxillae, some isolated teeth, and an extremely complete, yet distorted, cranium. The most astonishing thing about the skull is that it looks remarkably similar to that of a human skull. Note the platyops, platus coming from the Greek word that means flat, and opsis, meaning face. Thus making the name "Flat-Faced Man." Of course there are many differences than a human skull, but it is extremely similar to that of one.

Mother Daughter Relationship in I Stand Here Ironing by Tillie Olsen Es

Mother Daughter Relationship in I Stand Here Ironing by Tillie Olsen â€Å"I Stand Here Ironing† by Tillie Olsen If Only.... Almost every parent dreams of giving their children what they never had growing up. However, unavoidable situations cannot be changed and we are forced to make do with what life gives us. Life’s twists and turns are not always predicted, we get caught up with other things and lose sight of the important ones. In the story, â€Å"I Stand Here Ironing,† Tillie Olsen portrays the life and regret of a young single mother struggling to raise her daughter Emily. Olsen points out through uncontrollable circumstances in society, Emily’s mother is forced to become a working-class mother who must hold down a job and care for her child. To many the ideal mother-daughter relationship is not like the one we find is this story. This is neither the fault of the mother nor daughter. In the beginning, while she is ironing, the mother of a nineteen-year-old girl reflects on her daughter’s childhood. She is caught between feeling responsible for Emily’s unhappy childhood and realizes that she was powerless in making her life better due to the lack of alternatives. As she is ironing, the mother remembers back to when her eldest daughter was an infant. She was a young, inexperienced mother who followed â€Å"like the books said† (204) and considered Emily to be â€Å"the first and only one of [her] five [children] that was beautiful at birth† (203). During the worst years of the Depression, her husband deserts the family leaving them to fend for themselves. With no money or savings available to support the two, her mother is forced to find work and Emily is handed over to a variety of temporary ... ... her child. Olsen articulates the difficulties, obstacles, and struggles faced with non-privileged families in the story. The character of the mother in â€Å"I Stand Here Ironing† is one that is strong and wise. Throughout the story, she reflects on various events in Emily’s life that shaped the person she is today: self-sufficient and independent. At first while she is still young, she looks at her helpless daughter with guilt and pity because she is not able to give her the life she deserves. However, Emily grows into a young adult woman, Olsen points out the mother soon realizes that her daughter is a lovely, capable woman with potential. Her only hope is that Emily herself can and will realize it for herself. Olsen’s suggest that our circumstances shape who we are, but no matter the situation, we can still overcome them because there is potential in everyone.

Enterprises with appropriate technology are having a definite advantage over the others in the competitive business environment. Therefore enterprises should have very clear understanding of their technology needs and opportunities. Many telecommunications service providers in the world are in the midst of undergoing tec hnical and structural changes, whilst at the same time experiencing major growth.Competition and rapid technological advancements drive the present telecommunications industry. In Sri Lanka Mobile Communication Industry is rapidly growing. More than 12 million Mobile users are in Sri Lanka. Following figure shows the mobile subscriber growth. Cellular Subscriber Growth (1991 – 2009 June) 14,000,000 12,000,000 C u m u l a t i v e N o . o f S u b s c r i b e r s 10,000,000 8,000,000 Subscribers 6,000,000 4,000,000 2,000,000 0 Year Figure 1. 1: Mobile Subscriber Growth (1991 – 2009 June) Source: TRCSL Page 1Mobile Communication Industry in Sri Lanka Under a misty global economic cloud Sri Lanka’s economy grew in recent couple of years, but at a modest rate. The economy having achieved sustained growth over three decades averaging nearly 5% per annum, in conjunction with a modest population growth in comparison to other South Asian countries crossed the USD 2000 mar k in per capita income. Notwithstanding conditions of uncertainty, investment in infrastructure development continued at the macro level and Mobile Communication industry has achieved a considerable growth.The economic realities and new market developments during the last year turned out to be a stress test for all mobile phone operators in Sri Lanka. Ruptures emerged and the industry had to search for quick but durable fixes to remain viable. The entry of the fifth mobile phone operator, early in the year set the new reference price and forced a downward revision of pricing by all mobile operators. This caused a sharp reduction of the reference price by approximately 50%. Further to cutting prices, competition in the industry intensified and this resulted in a sharp rise in advertising and promotional activity.The combined effect of a significant drop in prices and high promotional costs compelled most industry players to consider serious adjustments to their business models and st ructures, a process that led to job losses in the industry. Leading operators recorded some growth in business volume in a growing market, but declining margins eroded revenue bases leading to operating losses. 1. 1 Objectives Main objectives of this repot are; 1. Assess Technology Level of Sri Lankan Mobile Communication Industry 2. Identifying main technology issues in the industry 3.Proposing technological solution for those issues 1. 2 Methodology Literature survey was done regarding the Sri Lankan and world Mobile communication industry. In the second step responsible staff members were interviewed representing all five mobile operators. Their views and information collected from literature survey Page 2 Mobile Communication Industry in Sri Lanka were analyzed. In addition to above Mobile communication equipment vendors were contacted for gathering information about new technologies and trends. Page 3Mobile Communication Industry in Sri Lanka 2 Technology Level of Mobile Indust ry In order to examine the technology level and capability, framework developed by Panda and Ramanathan (1995) can be used. This framework is based on the value chain concept, which identifies the primary and support activities of a telecommunications service provider, and uses step by? step procedure to analyze the technological capability needs in these activities and to develop indicators to measure the extent to which such technology capabilities have developed. 2. 1 HistoryAlthough telecommunication has a history of more than 150 years in Sri Lanka, the island’s mobile communication history extends to less than 25 years. Mobile phone technology first evolved in 1946 after the Second World War. The first Mobile network was established in North America. After 42 years, mobile technology was introduced to Sri Lanka. The first private mobile operator to enter the market in 1989 was Celltel Lanka Limited, which was later known as ‘Tigo’. In 2009 Tigo was acquired by Etisalat; Middle East telecom giant. The first mobile operator based its services on the E?TACS technology which offered basic voice services to Sri Lankan subscribers. Between 1989 to 1994 the Government took measures to introduce competitive cellular services by granting license to three mobile operators; OTC Australia (Pvt. ) Ltd, presently known as Mobitel (Pvt) Ltd, MTN Networks (Pvt. ) Limited, commonly known as Dialog GSM, and Lanka Cellular Services (Pvt. ) Limited currently known as Hutch. In 2009, the Government introduced more competition to the market by granting license to a fifth mobile operator, Bharathi Airtel which is an Indian telecommunication giant.From 2004 to 2010 Mobile communication industry in Sri Lanka had an annual growth of around 35? 40%. 2. 2 Assessing Technology Level World Technologies in Telecommunication is shown in Table 2. 1. It can be seen in the world still there are network operating mobile technologies of 1st generation, 2nd Page 4 Mobile Communication Industry in Sri Lanka generation and 3rd generation. By looking at the subscriber percentages belong to the networks it can be concluded that 1st generation technology networks will not last much longer as already it is 0. 01 percent of world subscriber base.Technology GSM CDMA2000 1x WCDMA CDMA2000 1x EV?

As still GSM technology has more than 80% of world subscriber base and GSM is enhancing with support technologies it is expected to last more years. 3G/3. 5G (WCDMA/HSPA) are most modern commercially available technologies. It’s seen that these technologies are capturing the market rapidly. According to related surveys, more than 96% of WCDMA networks have deployed HSPA, with the majority (over 52%) supporting a peak downlink data capability of 7. Mbps or higher. With 22% of HSPA network operators committed to HSPA Evolution (HSPA+). Page 5 Mobile Communication Industry in Sri Lanka 2. 3 Bench Marking Technologies used by Sri Lankan Mobile Operators and the world technologies are mentioned in the following Table 2. 2. According to the table Dialog and Mobitel have latest technologies comparing to other operators. When comparing with the World status Sri Lankan Operators are using state of art technology.

Also Sri Lanka is the first country which demonstrated HSPA+ in South Asia. Page 6Mobile Communication Industry in Sri Lanka 3 Technology Problems Recent years were probably the most challenging for the mobile communication industry in its history. Economic and industry turbulence heightened and industry leaders were forced to absorb the shocks in telling proportions while weaker operators were rendered vulnerable. The mobile communication industry deserves commendation for surviving trying economic, industry and regulatory challenges and for riding the tide. However, the cumulative effect was an entire mobile communication industry reporting operating losses.Following are some performance data of Mobile Operators in year 2009. Dialog Group reported negative NPAT of 1159 mill. Without recurring costs. In operation Etisalat reported a loss of approximately ~1600 mill. Hutch turn over was decreased by 61. 9% Mobitel reported a net loss of Rs. 395 mill. As margins become narrower and narrower operators are needed to find new opportunities in order to enhance revenue. But several technological problems are there as barriers for growing Mobile Communication Industry. 3. 1 Capacity Limitations In Mobile communication data traffic demand is rapidly increasing.Major bottle neck in providing higher data rates is limitations in transmission networks. Currently Mobile operators have not island wide optical fiber networks in order to provide higher capacities. Also to provide higher capacity at low cost, tradition al TDM based access networks are a barrier. So IP based networks need to be deployed. For this huge investments are needed but current financial status of all mobile operators is not healthy enough for that. Currently it is not possible to provide higher data rates when users move from UMTS (3G) coverage area to GSM/EDGE coverage area.Page 7 Mobile Communication Industry in Sri Lanka Currently the number of users can be catered by one cell has become a issue in mobile industry, because if there are more than possible no of users in the same cell, Users experience the congestion situation and as a result this cell need to be further brake in to two cells or covered by an umbrella cell to cater the capacity. When doing so different frequencies need to be assigned to the different cells and this will increase the interference to the users and quality would be dropped. 3. 2 Energy IssuesIn rural villages in Sri Lanka, electricity is either not available or is available only in limited q uantities. As a result, even if battery backup is provided for the Base Stations (BTS), the batteries do not get fully charged. Further, due to frequent interruptions in the power supply, the life of these batteries gets shortened, which in turn increases the operational cost to run services in rural areas. Unavailability of reliable power in semi? urban, rural and remote areas increases operational costs further because sufficient backup systems have to be maintained.Therefore sustainable green energy sources are essential to have need in future. But still in Sri Lanka Green Technologies like solar energy and wind power energy are not popular in Mobile industry. Also existing such technologies are not capable of successful operation of base stations. Unavailability of commercial power in rural areas is also affected to mobile operators to expand their coverage. Optional power sources are needed to expand coverage in small time duration with minimal cost. 3. 3 Frequency Spectrum Iss ues In Sri Lanka Super High Frequency (SHF) Band is highly polluted.SHF band includes frequencies between 3GHz and 30 GHz. In this band more than 10000 Microwave Links are currently operating. Especially in urban areas it is difficult to deploy new back bone microwave links due to interference. This has highly influenced for providing enough data capacity for Mobile Broad Band customers. Page 8 Mobile Communication Industry in Sri Lanka TRCSL has not allowed Point to Multi? Point backhauling technologies for telecom operators. With this technology number of microwave links need to be installed can be reduced and operators can easily deploy their back hauling networks. 3. 4 BSC/MSC BoardersIn early mobile systems, remote base station sites were controlled by the MSC or mobile switching center. But with current systems under 2. 5G GSM network BSC Base station controller controls the remote Base stations and under 3G network RNC Radio Network controller controls the remote node B sites , because of this scenario, It is a must to have several BSC/MSC boarders in the network and when users are moving via this boarders, the probability of drop of the calls are vey high reducing the network quality in those areas. For example, people in the boarder areas always experience call drops and bad call quality etc.Therefore improvement for this is necessary via the advancement of the technologies. It may be high capacity MSCs or BSCs or some other solutions. 3. 5 Tower Loading Microwave links are used as the main means of backhauling in mobile industry in Sri Lanka and these microwave links need to be fixed on towers with having line of sight. Usually each tower connects with more than one tower therefore always several links are need to be installed on a tower top. If its a hub site this number may increase to 10? 15 even more than 50 sometimes. Microwave antenna comes with 0. 6/1. 2/1. /2/2. 5m diameter; therefore this is a big equipment. Also it has a larger wind shield a rea, because of this big size and area and weight operators need high strength large towers to be implemented. If the antenna sizes and weight of this microwave links can be decreased it would be quite advantageous for the operators. Else new technologies like laser links, IR Links or smaller antenna sized IP links technologies can be developed to be able to guarantee the same level of availability. Then operators would be able to replace heavy microwave and use light equipment types. Page 9Mobile Communication Industry in Sri Lanka 4 Proposed Technologies 4. 1 Fiber Based Transmission Fiber based transmission is not a new technology in the industry. In Sri Lanka SLT and Dialog have their own fiber based networks. Fiber based transmission can cater quite high capacity data transmission. It can be used to implement either TDM/SDH based network or Packet/IP based network. Although SLT has a island wide fiber network, Dialog fiber network is still not widely spread. In fiber based solu tions fiber cables are drawn from core network sites to the remote Node? B/BTS sites.Usually a ring topology is used and it goes via hub sites, from hub sites fibers are drawn to remote sites. Figure 4. 1: Typical Fiber Based Mobile Network The problems with Fiber based transmission is the high initial capital investment cost and the time taken for the implementation. Most of the operators are not capable of affording such investment for their own fiber based infrastructure. Page 10 Mobile Communication Industry in Sri Lanka If a fiber network can be used for providing transmission for base stations, increasing data traffic demand can be easily fulfilled.Another option is to lease fiber network’s capacity from already deployed SLT or Dialog network. But leasing cost need to be highly considered. 4. 2 IP RAN Implementation of IP RAN (IP Radio access network) is the key to provide higher capacity. An IP ran with higher capacity to remote sites can reach higher speeds with curre ntly available HSPA+ like technologies. Figure 4. 2: HSPA Technology Roadmap According to the roadmap shown in Figure 4. 2, with the enhancements of HSPA+, Wimax /ADSL speeds can be passed or equalized with HSPA in the years to come.The IP radio access networks (IPRAN) consist of end to end (Remote sites to the core network nodes) transmission with IP/Ethernet networks. Easiest way to implementation of such a technology is fiber based IP network where higher capacity and less complexity can be achieved. 4. 3 EDGE Evolution for GSM Current 2G networks are inadequate for providing data speeds of GSM/EDGE networks. EDGE Evolution quadruples standard EDGE network speeds, promising downlink data Page 11 Mobile Communication Industry in Sri Lanka rates of 1. 2Mbit/s, though the standard has headroom for up to 1. 9Mbit/s.Similarly, uplink data rates of 474kbit/s are expected, although the standard specifies 947kbit/s. 3GPP standardized EDGE Evolution in 2007 (3GPP Release 7). 4. 4 Green Te chnologies Maintenance costs of networks in rural areas are high compared to urban areas, because of several factors such as poor transportation systems, difficulty in supply of spare parts and non? availability of skilled manpower. Due to lack of reliable power in rural areas, there has been a substantial increase in the usage of diesel for running engine alternators to keep telecom switching centers, transmission equipment and BTS s up and running.Currently more than 5000 Communication towers are there in Sri Lanka. This increases costs substantially. In spreading the reach of telecommunications in remote areas, renewable energy should be used to power relay towers in remote areas. By replacing diesel generators with solar panels in cell phone towers, tons of carbon emissions could be prevented from entering the atmosphere. Global Telecom emission in 2002 and estimated values in 2020 are shown in Figure 4. 3. Figure 4. 3: Global Telecom Emissions 2002 – 2020 Source: The Cli mate Group and Global e?Sustainability Initiative Page 12 Mobile Communication Industry in Sri Lanka Solar is a clean and effective way of harnessing energy. Also, the maintenance cost for the operation of solar equipment is comparatively lower as compared to diesel generators operated BTS towers. Solar generators have no carbon emissions and also help in preserving the environment for sustaining life on earth. It reduces global warming, as carbon emissions are null in solar devices. The manpower needed for the operation and maintenance for solar equipment do not require extra skill.The telecom majors in world have started operating mobile repeater and relay stations, which harness solar and wind energy with the wind turbines foisted on the telecom towers. The hybrid systems, involving solar photovoltaic systems and wind energy installations for this application assure uninterrupted supply of 2. 8 kilowatts of power daily. A master control installed at the site acts as a voltage sta bilizer, while a generator has been kept as a back? up for charging the batteries in case of emergency. Though the diesel generators are the lifelines of telecom towers, they contribute to significant carbon emissions.Going green and pushing the use of alternative energy sources like solar, wind and bio? fuel is the need of the hour; the government should provide high subsidies to help the telecoms taking this step, quickly and easily. Going solar is the way forward. Therefore as we can see above technologies are the candidate technologies for future enhancement of Mobitel network. According to the study these technologies can solve the main issues that were identified in this chapter. Therefore a strategy and a roadmap are required for timely implementation of the technologies in the network. 4. 5 LTELTE (Long Term Evolution) is a 4G technology which is emerging in the world now. When existing technologies are becoming obsolete, investments need to be done on new technologies. It i s assumed that 2G will become obsolete in near future. Page 13 Mobile Communication Industry in Sri Lanka Figure 4. 4: Envelope Curve of Mobile Technologies Figure 4. 4 shows the envelope curve of mobile communication technologies. It can be seen the technology is mainly improved focusing the deliverable capacity. See Figure 4. 5. Figure 4. 5 Expected Growth of Mobile Data Industry Mobile broad band services provide new opportunities for Mobile Operators.With LTE customer demands can be satisfied easily. Page 14 Mobile Communication Industry in Sri Lanka 5 Future Industry of Mobile Communication Current monthly operational cost of Mobile Networks is several folds higher than revenue which is the case in many technology introductions. By introducing green technologies operational cost can be reduced. Therefore a huge advantage can be taken in current price war. With low cost IP based technologies and Point to Multi Point Backhauling technologies can be reduce operation and maintenanc e cost also.Going for Fiber Networks can help to reduce operational cost by reducing huge TRCSL license charges need to be pay annually for Microwave Links. With those technology improvements turn over can be improved and hence investments can be encouraged because huge investments are needed in near future as Core Mobile Technologies are evolving day by day. Government need to be given intensives for investments in Mobile Technologies as it can energize the economy in return. Above mention technologies can reduce the environmental problems raised by Mobile Industry. Some of such issues can be listed as follows.Carbon Emission of more than 5000 Base Stations island wide Radio Frequency Pollution Currently Mobile Industry has influenced in culture also. Wide spread of pornographic contents is a major issue. Now recently all mobile operators have been agreed to implement technological measures to filter out such contents. Therefore by introducing mentioned technologies mobile operator will be able to overcome technological barriers as well as financial issues, marketing issues and environmental uses etc. Although Sri Lankan Mobile tariffs are the lowest in the region, customers are not satisfied with the service in general.This bad customer images Page 15 Mobile Communication Industry in Sri Lanka regarding mobile operators can be eliminated from the heart of the customers by introducing state of art, sustainable and low cost technologies. Page 16 Mobile Communication Industry in Sri Lanka 6 Conclusion Technology plays a vital role in any industry in today’s world. Mobile Communication industry is not an exception. Mobile Technologies are evolving very rapidly and customer expectations are also at sky level. In Sri Lanka 5 Mobile Players are operating in the industry and they use most popular and

Emotion and Behaviors Essay

This project requires that you observe two preschool-age children in the Child and Family Development Center (ground floor of the Alfred Emery Building) and, on the basis of your observations, report on a particular aspect of their development. In the following pages, three options will be presented–you may focus on either language development, play, or emotional behavior. Thus, the option you select will determine the nature of the observation you conduct, but it is also true that all projects must follow the same guideline. First, you must decide which of the three options you will pursue. Second, you should become familiar with the objectives of your observation (based on the descriptions presented in the following pages as well as any reading from the textbook that would prove useful in this regard). Third, you should begin planning your observation; this should include decisions regarding what you will focus on during your observations (e. g., behaviors, specific features of the physical and social context), what kinds of things you will try to take notes on in the course of your observation, which preschool class you will observe, and when you will plan to conduct your observation to assure that you will leave yourself enough time for a second chance should you fail to gather all of the necessary information on your first observation attempt. Fourth, you should conduct your observation, paying very careful attention to the behaviors and situations that you have (beforehand! ) decided are most import ant–in all cases, you will have to observe two children for 15 minutes each. Take notes and remember that these notes are all you will have to work from when writing your paper. I also would recommend that you allow yourself approximately 1 hour for your observation. This would allow you at least a few minutes at the beginning of the observation to get a feel for the classroom and the children in it and to identify the two children you will observe; ample time to observe each child for 15 minutes (which may be split into 5 minutes now, 5 minutes in a short while and 5 more minutes at the end of your hour); and even some time to make up for observations that don’t result in any useable information. Fifth, you must rely on your notes and the details of the assignment to prepare your paper. In all cases, I am asking that you provide some general, objective information about what you observed in each child, and that you interpret your observations in terms of what you’ve learned about preschooler development. In addition, the introduction of your paper should provide a brief description of who you observed, when you observed them and what was going on in the preschool classroom during your observation period. Finally, at the end of your paper, briefly comment upon your experience as an observer. For example, How easy or difficult was it? What did you learn? How confident are you in the representativeness of the behaviors you observed for each child? As usual, all papers MUST BE TYPED. You are limited to 3 typewritten pages so think carefully about how best to organize all of the information you wish to present. Papers are due at the beginning of class on Tuesday, April 15. *****The preschool schedule is as follows: There are three different preschool classes (children ages 3-5): one meets Mon/Wed/Fri, 8:30-11:30, one meets Tues/Thur, 8:30-11:30, and one meets Mon thru Fri, 12:30-3:30 pm). In all cases, there should be no problems if you observe (quietly) from the observation booths attached to each classroom, or from outside the playground fence. If you wish to observe from within the classroom, or if you wish to go onto the playground with the children, you will need the permission of the head teacher. Simply tell them about the project, mention the class and instructor’s name, and there should not be a problem (do this ahead of time! ). Following are descriptions of the three options, each focusing upon a different feature of preschoolers’ development. In this exercise, you will be concerned with describing and analyzing the child’s speech and determining such things as the depth and variety of his/her vocabulary. 1. It is important to look at the child’s speech in terms of Piaget’s concepts of egocentrism and sociocentrism. Egocentric speech is speech that does not take the other person into account; it is speech that, for all practical purposes, is private. There is no real effort to communicate with the other person; therefore, whatever is said is meaningful only to the speaker. Piaget identified three types of egocentric speech: (a) monologue, in which the individual talks only to himself and with no other persons present; (b) repetition, in which the individual repeats words and phrases over and over again as if to practice them or as if he simply enjoyed making the sounds; and (c) collective monologue, in which two or more persons are talking together but none of them is paying attention to what the others are saying. Each â€Å"conversation† is independent of the other conversation. Socialized speech, on the other hand, is public speech. It is intended to communicate with someone and each person takes into account what others are saying and responds accordingly. Q1: 2. Does the child engage in egocentric or socialized speech? What are the circumstances under which these types of speech are used? Vocabulary is the foundation of speech. We communicate by putting individual words together into properly constructed sentences and paragraphs. Presumably, the greater the number of words in our vocabularies, the greater the number and variety of sentences and ideas we can utter and transmit to others. Words have different meanings and serve different purposes. Moreover, words must be placed in the correct position within a sentence; thus, there are rules of grammar and syntax. Q2: What do you observe about the child’s vocabulary? In particular, examine the child’s speech for words that express relations and oppositions, for example, words such as and, or, not, same, different, more, less, instead, if, then, and because. Also, how varied or rich is the child’s vocabulary when he/she talks about the world and the people/things in it? Think in terms of general classes or categories of objects, persons, and events, then assess how many different words the child uses to discuss those categories and/or how many different categories the child uses. B. Observational Objectives To learn about the language production abilities of preschool children, and how children of preschool age use language as a means of social interaction. C. Procedure For this exercise, your purpose is to observe and record the language behaviors of children as they are engaging in social exchanges. Basically, you will need to write about the vocabularies demonstrated, the ways in which children use their language for the specific purpose of communicating with others (either adults or other children), and the degree to which language appears to be influenced by the setting in which it occurs. For this purpose, select two children and observe each of them for 15 minutes during a time when they have opportunity to interact with others in a small group setting–free-choice periods are probably best. (Do not try to observe two children at the same time! ). As you observe, take notes regarding the nature and variety of words used by each child (writing down exactly what the child says would of course be very useful), the child’s specific use of language to communicate with others, and the context in which all of this is going on. For each child, your paper should include a brief description of the language used (including information about vocabulary, communication and context) as well as an interpretation of each child’s language behavior in terms of what you’ve learned about development during the preschool years. II. PRESCHOOLERS’ PLAY A. Background Information Play is considered by some psychologists to be the most important activity in which the young child engages. Indeed, play activities pervade the lives of children from infancy throughout childhood. Some play seems obviously linked to the child’s observation of adults; other play seems to stem from the child’s fantasies and from experiences that she finds particularly enjoyable. There are a number of explanations of the major purposes of play. These range from play as getting rid of excess energy to play as a means of socioemotional expression. Play can be a group or an individual activity. Play is distinguished from non-play by its special characteristics, the most important of which are its voluntary nature and its complete structuring by the participants, with little regard for outside regulation. When play is governed by consistent rules, we say children are playing games. These rules give play a social dimension. The participants must put their own personal wishes into the background and abide by the requirements of the game and the wishes of the larger group. It is important to note that not everything children do is play, although they will sometimes try to make play out of what adults intend to be serious. Parten (1932) has identified six types of play, which are given in an accompanying list (next page). Remember that play, like all behavior, occurs in a physical and social context. Therefore, include in your report information on the equipment and materials the child was using in his play and who the child was playing with, if appropriate. B. Parten’s Six Classifications of Play or Social Interactions 1. Unoccupied Behavior: Here the child is not engaging in any obvious play activity or social interaction. Rather, she watches anything that is of interest at the moment. When there is nothing of interest to watch, the child will play with her own body, move around from place to place, follow the teacher, or stay in one spot and look around the room. 2. Onlooker Behavior: Here the child spends most of her time watching other children play. The child may talk to the playing children, may ask questions or give suggestions, but does not enter into play. The child remains within speaking distance so that what goes on can be seen and heard; this indicates a definite interest in a group of children, unlike the unoccupied child, who shows no interest in any particular group of children, but only a shifting interest in what happens to be exciting at the moment. 3. Solitary Play: This is play activity that is conducted independently of what anyone else is doing. The child plays with toys that differ from those used by other children in the immediate area within speaking distance, and she makes no effort to get closer to them or to speak to them. The child is focused entirely on her own activity and is uninfluenced by other children or their activities. 4. Parallel Play: Here the child is playing close to other children but is still independent of them. The child uses toys that are like the toys being used by the others, but he uses them as he sees fit and is neither influenced by nor tries to influence the others. The chid thus plays beside rather than with the other children. 5. Associative Play: Here the child plays with other children. There is a sharing of play material and equipment; the children may follow each other around; there may be attempts to control who may or may not play in a group, although such control efforts are not strongly asserted. The children engage in similar but not necessarily identical activity, and there is no division of labor or organization of activity or individuals. Each child does what he or she essentially wants to do, without putting the interests of the group first. 6. Cooperative or Organized Supplementary Play: The key word in this category is â€Å"organized. The child plays in a group that is established for a particular purpose: making some material product, gaining some competitive goal, playing formal games. There is a sense of â€Å"we-ness,† whereby one definitely belongs or does not belong to the group. There is also some leadership present–one or two members who direct the activity of the others. This therefore requires some division of labor, a taking of different roles by the group members, and the support of one child’s efforts by those of the others. C. Observational Objectives To learn about the distinguishing characteristics of different forms of play, specifically according to Parten’s classification of play behaviors. D. Procedure Familiarize yourself with Parten’s classifications of play as described above. Select two children in the preschool and observe each of them for 15 minutes, preferably during a free-choice period when the children are free to move about the room and play with who or what they wish. (Do not attempt to observe both children at the same time! ) As you observe each child, look for examples of each type of play or social interaction as described by Parten. Also, in addition to classifying each child’s play behaviors, observe whether there are any patterns to their play. For example, are there particular situations in which a child tends to be an onlooker, but in other situations he/she engages in parallel or cooperative play? As you observe, you should take notes regarding these relevant issues so that you will have something to work from in writing your paper. For each child, your paper should include a brief description of the types of play exhibited (including information about which type(s) are exhibited most frequently) and the social context which characterized each type of play. Additionally, you should provide an interpretation of your observations based on what you’ve learned about development during the preschool years. III. EMOTION BEHAVIOR A. Background Information Emotions are such a basic part of our psychological beings that we sometimes take them for granted. Some of our emotions are clearly identifiable by us. We know when we are angry, frightened, or joyous. At other times, however, we can have feelings that are not so clear; we may not be able to label what we feel. Whatever the case, emotions are internal experiences that are private and directly accessible only to the individual experiencing them. This being so, we cannot state with certainty what emotion another person is feeling. She must tell us, or we must infer the emotion on the basis of the individual’s behavior, facial expressions, and the event that preceded and might have caused the feeling. A child’s emotional behaviors become more refined and extensive as she matures. Therefore, a four- or five-year-old will typically be more emotionally expressive than a two-year-old. In this exercise, you will be trying to gain some understanding of the child’s emotional behaviors, of the range of her emotions and the kinds of situations that prompt these behaviors. Again, you can only infer what the child is feeling and cannot observe emotions directly. Therefore, be cautious in your interpretations and concentrate on the child’s obvious behaviors and the contexts in which they occur. 1. There are several emotions that are commonly found in preschool children: aggression, dependency and fear. Aggressive behavior is frequently defined as behavior that is intended to physically or psychologically hurt another person (or oneself) or to damage or destroy property. An important issue is whether a behavior is intentionally aggressive or simply an accidental occurrence. Further, it is argued by some that in order for a behavior to be termed aggressive, the aggressor must feel anger or hostility toward the â€Å"victim† and must derive satisfaction from hurting the victim. This kind of aggression is called hostile aggression. In contrast to hostile aggression, there can be cases where the aggressor is interested only in getting some object from the victim or achieving some goal. This is called instrumental aggression, and it need not involve anger or hostility. Observe the child’s behavior for instances of aggression, either toward  another child or an adult, or towards objects in the environment. Be certain to differentiate between intentional, hostile and instrumental acts of aggression. What kinds of situations or frustrations make the child angry? What behaviors by other people anger the child? How does the child express his/her anger? Dependency consists of such behaviors as clinging or maintaining proximity to adults or other children, seeking approval, recognition, assistance, attention, and reassurance, and striving for affection and support. It is important to recognize that all of us are dependent. The issue is to what degree and under what circumstances we show our dependency. It is also useful to distinguish between two basic types of dependency: a) instrumental dependency, which essentially is the necessary reliance we have on others for certain things that are beyond our capacity to do; and b) emotional dependency, which is a need to be near others and to have their support, affection and reassurance. It can also be the unwillingness or the selfperceived inability to do things for oneself that one can or should be able to do. It is important that, where possible, you distinguish instrumental dependency from emotional dependency behaviors. It is also important to note that as children mature, the characteristics of their dependency behaviors change. Very young children are likely to show clinging and proximity-seeking behaviors, whereas older children, who also have greater cognitive abilities, will likely seek attention and approval. Q3: 3. Fear is demonstrated by such behaviors as crying, withdrawing, seeking help, and avoiding the fear-producing situation. Fear can promote both dependency and aggressive behaviors. Nonetheless, fear can be expressed in such a way that it, and not aggression or dependency, is the primary emotion. Q4: 4. In what situations or activities is the child dependent, and, for example, seeks the presence, direction, or assistance of others? In what situations is the child independent and does not seek direction or assistance from others? What kinds of objects or situations appear to scare the child? In what ways does the child express his/her fears? How does he/she deal with his fears (e. g. , by withdrawing, confronting the fearful situation, seeking help)? In addition to the emotional behaviors just discussed, there are other feelings that children are capable of experiencing and expressing. You should be alert to as many of the child’s affective states as possible. For example, there are the feelings of pleasure and displeasure, frustration, boredom and sadness. Like adults, children will differ as to how accurately they can identify and/or express what they feel. Q5: What kinds of things does the child find pleasant? What activities, play materials, stories, games and so on, seem to be particularly attractive to the child? How does the child express that pleasure? Q6: What kinds of things are unpleasant or uncomfortable for the child? In what situations does the child appear to be ill at ease? How does she express her displeasure? Q7: Are all or most of the child’s feelings expressed with equal strength, or does their intensity vary with the particular feeling or situation? B. Observational Objectives To learn about the differences in children’s emotional behaviors and the range of emotional responses in preschool children. C. Procedure Select two children, observe and record each child’s behavior for a 15-minute period (do not attempt to observe both children at the same time! ). Record behaviors in as much detail as possible (attending to the kinds of things that would help you answer the above questions) and be sure to include descriptions of the physical and social context as they apply to the emotional behaviors observed. IT IS RECOMMENDED THAT YOU OBSERVE CHILDREN DURING THE VERY BEGINNING OF THEIR PRESCHOOL CLASS SO THAT YOU WILL BE ABLE TO SEE THEM AS THEY ARE BEING DROPPED OFF BY THEIR PARENTS AND THEN MAKING THEIR INITIAL ADJUSTMENT TO THEIR PRESCHOOL SETTING. Your paper should include a brief description of each child’s behavior (including the different kinds of emotions, the contexts in which they occurred and the relative frequency of each expression) as well as an interpretation or comment on each child using some of the questions and background information provided above. Finally, compare the two children, looking at the range of emotional expression, intensity of expression, and what evokes the emotional responses. In short, summarize how the children differ from each other in this area of functioning.
