Love in the Western World Essay Example Essay Example

Love in the Western World Essay Example Paper Love in the Western World Essay Introduction This paper will trace in general the different views on love as expressed by the different speakers in Plato’s Symposium and explore in detail the theories of Eros, Philia, Storge and Agape and the bearing it has on the notions of erotic love, filial love, sacrificial love and spiritual love. Another area that will be drawn into focus is the theory of â€Å"platonic love† based on Plato’s hypothesis. The context of the symposium is a get-together of the students of Socrates who get to talking and decide to take turns and speak in praise of Eros, the God of Love.Of the speakers Phaedrus speaks first and talks about the virtuosity Eros promotes in those who experience love. He talks about the awareness that true love can inspire in humans so that man becomes conscious of the noble qualities of honor, loyalty, courage and fidelity.Pausanius is the next to speak and dwells on the different kinds of love, from the common banal love to the higher, spiritual kind of lov e. The earthy love is not as noble as the intellectual love which is more faithful and elevates the mind and is completely devoid of desire. According to him the pursuit of higher knowledge and wisdom is the more honorable and the wantonness of physical love is shameful.Eryximachus talks about the concept of good love that helps man to be judicious and methodical. Eryximachus is a doctor and philosopher and talks about love beyond relationships, about intellectualism, the love of ideas, concepts and the fine arts like music. He speaks of the advantages love brings to humans, the most important being the ability to discern between honor and dishonor. He believes that there are opposing kinds of loves in every living being including animals and plants. However, true love is achieved through a synthesis of these opposing elements and that it can be the fountain and source of power, friendship and happiness (Plato’s Symposium).Aristophanes, the jester and humorist came up with th e concept of love as man in search of his soul mate and partner in order to feel one complete whole. He talks about man being split into half by Zeus for threatening to over run the Gods. Later Zeus modified his terrible act and allowed the two halves to marry as man and woman. It is said that ever since the two halves have been in search of the other.Socrates himself speaks last of all and talks of love as being the human desire for knowledge, wisdom and beauty. Love is the desire for what is beautiful and may not necessarily mean beauty in itself. According to Socrates love is the mere interface between what he desires and the object of his desire. When man has achieved real love he will be able to create beauty, conceptualize perfection and become wise and virtuous.In Greek mythology Eros is one of the three oldest Gods along with Cronos and Chaos and stands for love. The word ‘erotic’ is derived from the God of love, Eros, who encourages and endorses all those who s eek him to perform acts of virtue and merit. As has been mentioned before, all those present at the party or symposium have laid down their postulates and have spoken about different kinds of love and what it does for man. To further explore the concept of the various kinds of love let us consider the broad definition of these categories: Agape, Storge, Philia and Eros.Agape stands for spiritual love, the kind of love God has for his creatures and the love man strives to return. This kind of love transcends physical boundaries and is a higher form of love which finds fulfillment in just being there. It kindles spirituality and is perfection itself. Nothing can tarnish this kind of love and to most mortals seems almost impossible to attain. We can find examples of this kind of love in Christianity. In literature, I have found this kind of love being depicted in certain kinds of love lyrics that belong to the Renaissance age. In Petrarch’s poetry for instance, the poet’s object of desire, the enigmatic Laura, is continually shown as someone unreachable. Laura’s eyes are compared to stars; her face is often described as being so radiant as to make looking at her impossible. This imagery often ties up with how the apprehension of God is described in Christianity. Here, the conflict between Eros and Agape is continually present. The poet often feels helplessly tied between the demands of the earthier, physical Eros and the spiritual, the allegedly purer kind of Agape (Houston).Storge is synonymous with love that engenders sacrifice and purity. This is the kind of love parents feel for their children. This kind of love does not wait for reciprocity to grow and is there notwithstanding. The story of Abraham and Isaac is an interesting biblical instance of these two kinds of love where Storge is compelled to be sacrificed for the greater Agape. In order to prove the full extent of his Agape, his total devotion to God, Abraham is asked to sacrifice the thing he loves most. This happens to be Abraham’s son Isaac, the person for who he feels the greatest Storge. In the biblical context, Agape is undeniably higher than Storge. Abraham is therefore first made to prove the full extent of his Agape before God relents and lets him keep the object of his Storge. Other instances of pronounced Storge in literature include the love Cordelia feels for her father, King Lear in Shakespeare’s play. In this case however the Storge is made to complete its sacrifice in a sense because both the king’s beloved daughter and the king himself die in the end.Philia, or brotherly love, exists between friends, brothers and neighbors. This kind of love helps people to bond closely without being passionate or amorous. This kind of love prompts the feeling of camaraderie and brotherhood. A good example at hand would be the kind of love soldiers have amongst each other, where they bond intimately and share their joys and sorrows toget her without a hint of any physical attraction or manifestations. In Greek history, I have noticed the love depicted in the story of Damon and Pythias to be of this form. In the legend Damon and Pythias both survive Dionysus’ wrath because of their intense love for each other. But in another tale from the bible, the ending is not nearly as fortunate. Cain and Abel, sons of Adam and Eve, at first loved each other in the truest sense of Philia. However, with the preference God showed for Abel’s sacrifice of animals over Cain’s agricultural offerings, Cain’s love turns to intense jealousy and he ends up killing Abel. This is possibly the best known example of Philia getting overturned.Eros is passionate love, which can in most cases be closely linked to physical attraction and sexual love. Eros is often closely associated with the animal kingdom and therefore classically considered to be a lower form. Eros can often contend with Agape as we have seen earlier. And a popular example of this is in Shakespeare’s Romeo and Juliet. The love that the two young nobles feel for each other is no doubt arising from a certain attraction, or Eros. And yet the manner in which they express their love for each other in a language that is similar to that of Agape. Romeo and Juliet address each other in abject terms, making it a love not of equals but of one subservient to the other. This of course is one of the most common features of Agape.Although classically Eros is considered to be a lower form than Agape, as we have seen discussed in the Symposium, I personally feel this is not entirely fair. It is true that people often consider it nobler to love a person without wanting to possess him or her in a physical or earthly way. By implication this means that a person loves someone for more than their physicality, that is to say a love founded on something deeper than superficial beauty. This is true in theory, but not always in practice. We often find that the Agape is more often than not directed towards someone of higher social standing, or towards a woman who is unreachable, like a noblewoman or even the queen. This amounts to nothing short of sycophancy sometimes. Is it then less hypocritical than loving someone for their appearance?Eros is also equated with the animal kingdom and is therefore considered â€Å"lower.† But why should something, that takes place in the natural world, be considered lower? If animals love each other erotically, does it not make it a more natural, or even a â€Å"higher† love? After all this kind of love is based on the truth of the body’s responses to the beloved; if someone is beautiful and attractive physically, why should it be wrong to feel attraction or love for this person? Even if it is based only on appearances, Eros is more genuine. There is no verbal intrusion that allows lovers to lie to each other or praise each other in hollow terms.Philia too I think is of ten under-rated in the present generation. Friends can often feel a lot of love between them without it being the Erotic or even the Agape type of love. We have been brainwashed by popular movies and books into always expecting friendships to turn into love as that fits in with the perfect happy ending of the plot. But why should this be? Why is simple, platonic love that expects nothing physical or romantic in return be less of a love than any other kind? After all, is it not nobler for two friends to love each other in spite of the fact that they have nothing physical or romantic to gain from each other?Storge also is often under-appreciated in popular culture. Love that exists within families has become such a rare instance in the days of divorce and estrangement that perhaps more of art needs to depict it now, more than ever. People seem to forget that our families are what we are born into. We carry our parents’ genes and share them with our siblings and nothing or no on e else can ever change that. It is true that we are often unfortunate in this regard and there are many children brought into this world in an unloving family, but even so the love that exists between members of the family is something that precedes life itself. Just to think about what a pregnant mother endures for nine months and so many years following the birth, is enough to prove the argument.In conclusion, I think it is fruitless to spend hours debating on which form of love is higher than the others because each kind of love, whether borne out of devotion, lust, filial ties or friendship, is a distinct kind of love. A sort of love that is unique to itself and therefore deserving of special attention. Instead of trying to compare them it is perhaps best to be grateful to know that they all exist.Works CitedDe Rouguemont, Denis. Love in the Western World.

Private Prisons essays

Private Prisons essays In recent decades, there has been a trend developing in America towards the privatization of Americas prisons. Independent companies have contracted, built and staffed prisons in several different states instead of having the government in control of these facilities. There is still much uncertainty, however, if private prisons will be able to succeed. Some companies have failed while others cling to mediocre revenues. Some people believe that these measures will save taxpayers money while other are afraid that private prisons have no real interest in rehabilitating prisoners. Why have prisons been moving into private hands in this modern era? The most obvious answer would come from simple economics. If a business feels that there a profit to be made, even in an area that is usually thought of as a part of the public sector, it will try to get its foot in the door and make that profit. There is also a feeling among many people that public-run institutions are not cost efficient. People theorize that if a private company were to control certain institutions that they can remove the bureaucratic red tape and run a more cost-effective and efficient business. This theory is just one that supporters of the privatization of the prison system support. One major flaw of such a system is that if these prisons are being built in order to make money for a company, then the prison has less desire to get rid of its workforce. An ideal privately run prison would have to be one that is packed with able-bodied workers. For these prisons there would be less desire to release inmates early, which would make good time given to inmates something that is less desired. Even this flaw, at least presently, as revoking "good time" is a punishment used in only about 10 percent of cases. The government retains control of parole decisions and the authority to take away good time, which accrues automatically unless revoked b...

In addition, television can also be very important in promotional activities, involving business promotions among others. In the current world, television has become one of the most indispensible tools for education (Zettl, 2007). This is very helpful even to the students. Television always helps in making students get to acquaint themselves with several things. This is because, in the televisions, there are several programmes designed or literary documentaries, as well as literary programs (McCarthy, 2001). These are very important to the students. In this respect, it is of crucial significance to note that television always helps students to acquire more knowledge in the same ways that reading books always contributes. Television is also a source of entertainment. In summary, the complex integration of entertainment, education, business promotions, as well as communication in all aspects is very important. As such, it was very crucial for me to consider television as my media type of

Police statics discussion 2 - Assignment Example 1). Finally, the data published by the US Department of Health and Human Services focus on drug use, alcohol use, tobacco use, substance abuse, among others (US DHHS, 2010). What are the major strengths and weaknesses of each? The strengths of the FBI reports are the availability and accessibility to crime reports on the most updated manner, where the latest statistics provided is for the year 2013. The weakness is that some data are not provided; for instance, the site disclosed that in violent crimes, clearance and arrest data are not available (FBI, n.d.). For the NCVS, the strength is the clear structure of the reports; while the weakness is that the latest information available is 2012 (Bureau of Justice Statistics, 2013). Finally, the information provided by the DHHS is also comprehensive in the area of drug use; however, the weakness is that the latest available statistics pertain to the year 2010 (US DHHS, 2010). Which of the three different examples do you think is the most useful from a practitioners perspective and why? From a practitioner’s perspective, the most useful would depend on the statistics needed as well as the information on the type of crime that the practitioner needs. Yet, the most current and updated statistics provided by the FBI is deemed to be most relevant since it provides the most updated information that reveals current and historical patterns. US DHHS.

Anglia Local News Assignment Essay Example | Topics and Well Written Essays - 4000 words

Anglia Local News Assignment - Essay Example (Gillan2010) Also unlike the traditional host, it is the provider who manages the service implying that the consumer only has to have a computer and internet to access the service. Another feature of cloud is that it can be private or public. A public cloud is offered (sold) to anyone via the internet whereas a private cloud refers to a proprietary network that is only provides to a limited group of individuals. Whether one goes for the private or public cloud, the goal is to render scalable computing services. Infrastructure-as-a-Service (IaaS) Infrastructure-as-a-Service (IaaS) refers to a model whereby cloud providers deliver and control Information technology resources such as storage, computation and network capacity. (Blokdijk & Menken 2009) By this, cloud providers own, manage, render as well as distribute Information technology resources more effectively and conveniently to their subscribers. Platform-as-a-Service (PaaS) This refers to a set of software and development tools provided by a cloud vendor as a hosted infrastructure. Through this developers can be able to create applications running on the provider’s platform via the internet. (Blokdijk & Menken 2009) Platform-as-a-Service providers may use AP1s, web portals as well as gateways that are installed in a client’s computer. Examples of PaaS are GoogleApps and Force.com. Software-as-a-Service (SaaS) This refers to a model in which the vendor provides the hardware and software infrastructure as well as the software product that interacts with the user through a front-end portal. The range of services provided by SaaS is very broad. Examples of this include We-based Mail, database processing as well as inventory control. (Blokdijk & Menken 2009) Because the applications and the data resides with the host provides it enables the services to be accessible from anywhere. Benefits of cloud services By adopting cloud computing, some of the benefits an organization would accrue as would inc lude the following: First, cloud computing saves time. This is because by an organization relying on using installed software’s to meet their needs they stand the chance of spending more time procuring, mastering and managing their programs. (Velte & Robert 2009) However a business saves time upon adopting cloud since some cloud vendors offer software as a service, hence an organization is spared the inconvenience of managing their programs. Secondly a business stands fewer chances of glitches upon cloud adoption. This is because services offered through cloud require few versions. Therefore there is less upgrades needed and it becomes easy to implement considering the fact it is the cloud providers who implement this. (Velte & Robert 2009) Also considering the fact that most businesses incur problems in integrating software with other similar applications which makes it hard to share data, cloud enables user to integrate applications such as management systems, emails and of fice applications reducing cases of productivity glitches. It has also been known that cloud promotes conservation of the environment. This is considering the fact that personal computers only utilize 10 to 20 percent of the capacity; this implies there is a large percentage in energy waste. Therefore by pooling resources in cloud based systems there is energy savings on the life extended by personal computers. Another great advantage of the cloud is increased access

What is dyslexia?

What is dyslexia?   Ã‚  Ã‚  Ã‚  Ã‚  It has been 100 years since the first case of developmental dyslexia was described. Hitherto numerous researches had shed light on the causes and consequences of this disorder but the debate concerning its definition is still highly contented. In this essay, I will first answer the question of what is dyslexia and then move to the debate of whether it has a genetic basis.   Ã‚  Ã‚  Ã‚  Ã‚  Firstly, I will introduce what has been done in the early research of dyslexia and then tried to find a definition for us to understand dyslexia properly. Secondly, I will introduce the research for supporting the view that dyslexia has a genetic basis. 1.1 Early history of research on dyslexia   Ã‚  Ã‚  Ã‚  Ã‚  Reading, a complex behavior that requires a set of cognitive skills, has been highly valued by society and is a key component to education. An inability to read has profound social and psychological consequences. Several scholars in the 19th century studied the loss of the ability to read or understand writing.   Ã‚  Ã‚  Ã‚  Ã‚  Kurrmaul in 1877 describe the reading difficulties of literate brain-damaged patients as word-blindness. It is only in 1887 that a German ophthalmologist, R Berlin, first used the word ‘dyslexia to describe reading difficulties caused by cerebral disease or injury. However, having read articles published by Hinshelwood in the 1890s and early 1900s, W.P Morgan (1895) points out that a patient can be suffering from dyslexia without cerebral disease or injury. He quotes the case of a boy who has reading difficulties even though he has suffered no apparent brain damage. Though for a long time, the problem of dyslexia is widely studied, dyslexia was not a common knowledge for more than half a century and the concept of dyslexia was not familiar and unclear to many people. People need to understand what dyslexia is in order to help ones inflicted with the disease. 1.2 The definition of dyslexia   Ã‚  Ã‚  Ã‚  Ã‚  Dyslexia is a neurological disorder with a genetic origin and behavioral signs which extend beyond problems of written language. Early research confined the dyslexia into a medical model and thus clinical practice fail to distinguish a dyslexia patient from normal readers. In the 1968 World Federation of Neurology meeting, a definition of dyslexia formally introduced and stated that dyslexia is a disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence and socio-cultural opportunity. It is dependent upon fundamental cognitive disabilities which are mostly of constitutional origin. Many scholars criticize this definition. Firstly, the terms are vague as there are insufficient examples to illustrate conventional instruction or to point out the criteria of adequate intelligence and to explain the meaning of socio-cultural opportunity. These scholars point out that the biggest weakness of this definition is exclusio n. The definition only states what a person with dyslexia should not be and does not include criteria for its positive diagnosis other than to state that it is a reading difficulty dependent on fundamental cognitive disabilities (Snowling, 2004). Although its definition debatable, it is applied by the diagnostic and statistical manual of mental disorders and the international classification of mental and behavioral disorders for many years.   Ã‚  Ã‚  Ã‚  Ã‚  Researchers have never stop on the medical model. Without positive diagnosis criterion, doctors cannot differentiate children with specific reading difficulties and children who have reading difficulties because of a more general learning problems. Scholars have adopted tests through the comparisons of verbal IQ (intelligence quotient) and performance on reading tests of children with reading retardation and skilled reader in a hope that it could identify the children with dyslexia. Nonetheless, a number of findings such as Morton and Frith (1995) highlighted that it is not correct to assume that literacy problems are the only symptoms of dyslexia. These tests are purely behavioral definitions and the diagnosis is relative. For instance, there are many examples that show discrepancies with the predictions carried out by those researches. Some dyslexia children after receiving highly effective training in decoding non-words would score well and many children with r eading problems can improve their reading ability by having a better relationship with their teachers. Overly depending on these tests as a short cut to diagnosis would run the risk of excluding dyslexic children with reading problems and involve children who only show mild positive signs of dyslexia. The definition that concerns dyslexia as synonymous with specific reading difficulty has failed to be self evidence because it only focuses solely on reading and IQ-test performance and other tests.   Ã‚  Ã‚  Ã‚  Ã‚  One way out of this dilemma is to consider dyslexia as a disorder that has multi-levels of description. Rutter and Yule (1975) pointed out that the specific reading retardation is usually multi-factorially determined opposed to the claim that dyslexia is a unitary condition. Being a developmental disorder, dyslexia can be expected to have behavioral features that will change with maturation and response to environmental interactions (cf.Bishop, 1997). It may therefore be unrealistic to agree upon a simple and unchanging definition of dyslexia. Frith (1997) argued that there are causal links from brain to mind to behavior that must be considered when attempting to understand dyslexia. It is important to seek explanations at the three different levels in this causal chain namely the biological, the cognitive and the behavioral, in order to develop a comprehensive theory of why some children fail ‘unexpectedly&tsquo; to learn to read(Morton and Frith, 1995). Mo reover, the environmental factors will act as a stimulus to intensify or meliorate the condition of these three levels.   Ã‚  Ã‚  Ã‚  Ã‚  The common ground of the study of dyslexia, agrees that dyslexia is a neuro-development disorder with a biological origin and behavioral signs which extend far beyond problems of written language (Frith, 1997). The idea of dyslexia as a syndrome with a neurological basis springs from the work of Tim Miles, Elaine Miles and many intelligent students. It helps to solve the paradoxes that exist in defining dyslexia. Morton and Frith (1997) had developed a framework with three levels and environmental influence in a neutral view to describe a descriptive definition of dyslexia.   Ã‚  Ã‚  Ã‚  Ã‚  The past 15 years have seen a continuing increase in research effort aimed at identifying the biological underpinnings of dyslexia. Galaburda (1989) demonstrated abnormal symmetry in the structure of the planum temporal; Livingstone et al. (1991) identified cellular migration abnormalities in the magnocellular system of the brain which have been related to behavioral findings by Cornelissen et al.(1995). Genetic linkage studies with dyslexic families have identified regions on chromosomes 15, 1 and recently 6 (Cardon et al., 1994). Thus, restricting the discussion to behavioral observation is no longer necessary. This gap has been widened by cognitive neuro-science which insists that there is a space for the scientific study of the mind and brain and not just behavior (Frith, 1995). Cognitive level of explanation can be a bridge that links brain and behavior together. Cognitive abilities can be explained by Cognitive theories through observable behavior. The poor reading performance can be termed as a cognitive dysfunction which in turn can be explained by a brain dysfunction. In addition, this causal links chains from brain to mind to behavior has to be set within the context of environmental and cultural influences. Figure2(Mortan and Frith 1995)   Ã‚  Ã‚  Ã‚  Ã‚  An illustration of the causal modeling of dyslexia with the hypothesis of a phonological deficit hypothesis now shows in figure 2. In this figure, Morton and Frith in 1995 argued that when we try to explain a developmental disorder, we have to make a distinction between different levels of description. In the biological level and environmental level, we can look for causes and cures and in the behavioral level we can observe and assess the patient. Then the cognitive level lies in between these levels and have links with the rest of the levels. Here, the intuitive clinical impression can be captured and that the presenting disorder is a distinct and recognizable entity despite variable symptoms. This notation enables different theories about a disorder to be represented in a neutral fashion (Frith, 1995). The proposal of a phonological deficit as the cognitive basis of dyslexia has a strong theoretical and empirical support that it has been widely accepted. Starti ng on the biological level of figure 2, it is supposed that there is a congenital dysfunction of left-hemisphere perisylvian brain areas which affects phonological processing (Galaburda, 1989; Paulesu et al., 1996; Rumsey et al., 1992). Furthermore, the evidence for a genetic origin of dyslexia is increasingly compelling (Pennington, 1990). However, this theory also has its pitfalls. One of the biggest weakness of the phonological theory is it does not effectively explain the occurrence of sensory and motor disorders in dyslexic individuals. People who support the phonological theory typically have dismissed these disorders as not part of the core features of dyslexia. They consider their co-occurrence with the phonological deficit as potential markers of dyslexia instead of treating them as a causal role in the aetiology of reading impairment (Snowling, 2000).   Ã‚  Ã‚  Ã‚  Ã‚  In the domain of neauro-cognitive causes study of dyslexia, there are two other theories: the cerebellar theory and the magnocellular theory. The former one is that the dyslexics cerebellum is mildly dysfunctional and that a number of cognitive difficulties ensue, whereas the latter one postulates that the magnocellular dysfunction is no restricted to the visual pathways but is generalized to all modalities (Ramus et al, 2003). These three theories do not contradicted each other but potentially compatible. When it refers to the cognitive level, three theories imply a processing deficit. Fast temporal processing may be a basic characteristic of all perceptual systems, visual as well as auditory, object-based as well as speech-based. On the other hand, the slower-than- normal perceptual processing might affect the development of a phonological system (Frith, 1997). 1.3 Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Any definition should be seen as a hypothesis and to be rejected if future findings disprove it. As Tim Miles said that, a diagnosis of dyslexia is, in effect, a sort of bet. The definition in the framework of biological, cognitive and behavioral level within the interaction of cultural influences depict the dyslexia as a neuro-developmental disorder with a biological origin, which affects speech processing with a range of clinical manifestations (Frith, 1997). In this definition, it appears that the cognitive level of description provides a unifying theory of dyslexia. Such a theory is necessary to pool together the numerous different observational strands in this most intriguing and subtle disorder.   Ã‚  Ã‚  Ã‚  Ã‚  After the discussion of definition issues in dyslexia, we turn to focus on the approval that dyslexia has its genetic basis. We will first look at the study of heritability in dyslexia and then to talk about the genetic findings for supporting dyslexia has a genetic basis.   Ã‚  Ã‚  Ã‚  Ã‚  The rapidly accumulating evidence suggests that developmental dyslexia is one of many common familial disorders. The genetic explanations of dyslexia are rather convinced by research that uses the newly genetic techniques and statistical methods in the genetic study of dyslexia. Although most findings cannot be replicated as there are many variants need to be identified. We still can believe that dyslexia has a genetic basis by the evidence of the genetic study of dyslexia. 2.1 Famaliality of Dyslexia   Ã‚  Ã‚  Ã‚  Ã‚  The question of whether dyslexia has a genetic basis has been studied for a very long time. Numerous researches have been conducted. Among them, there are a number of findings that suggest developmental dyslexia is hereditary. Orton in 1925 hypothesizes that children born in a family of dyslexia have great chance of being dyslexia. According to a recent estimation made by Gilger, Pennington and Deferies in 1991, the risk of a son with a dyslexia father to be a dyslexia is approximate 40% and about 36% if the mother is dyslexia. Moreover, if both parents are affected, the risk and severity of dyslexia in the child would greatly increase. Nevertheless, for the girls, this ratio is relatively lower, at about 20% regardless of the gender of the affected parent (Childsfinucci,1983;DeferiesDecker,1982;Pennington,1991).However,the higher familial aggregation of reading problems is insufficient to prove that dyslexia has genetic basis. The environment shared by families a re strongly influence their reading ability. 2.2 Twins Studies   Ã‚  Ã‚  Ã‚  Ã‚  The twins studies can help us understand the complexity of the interaction between genes and environment in some degree. The first kind of twin studies is the comparison of concordance rates that could evaluate the hereditary basis of dyslexia as a clinical condition. The second evaluates the reading performance of twins for estimating heritability coefficient by analyzing various indicators of reading performance. Thus, it is important to diffrentiate these two types of twin studies.   Ã‚  Ã‚  Ã‚  Ã‚  In the first kind of twin study of dyslexia, researchers compared the concordance rates in monozygotic (MZ) twin pairs the identical twin pairs and dizygotic(DZ) twin pairs the fraternal pairs. Regression counted in the research dues to the assessment of environmental factors and its interaction with genes in reading disabled. The results show that at least one member of every pair had reading problems. Moreover, MZ has a higher concordance for reading disability than in DZ twin pairs (Hermann, 1959; Zerbin-Rudin, 1967;Decker and Vandenberg,1985). By comparing the findings of the concordance rates in twin pairs we can imply that developmental dyslexia has a genetic aetiology.   Ã‚  Ã‚  Ã‚  Ã‚  In the second type of twin pairs, a vast number of studies have reported MZ and DZ twin correlations for various measures of reading performance (Grigorenko, 1996). MZ correlations implied the presence of genetic influence through the comparison with DZ correlations. However, heritability estimates are varied. Some of the variability can be due to the fact that the sample size of those main researchers was relatively small. In addition, some twin studies suggest that only certain reading-related skills are inherited. Thus it has been shown that word recognition, phonological coding show important genetic influence, whereas reading comprehension and orthographic coding do not (Olson, Wise,Conners,Rack,Fulker, 1989). Because the latter one significantly influenced by the environmental factors. 2.3 Pattern of Transmission of Dyslexia   Ã‚  Ã‚  Ã‚  Ã‚  Researchers had conducted a number of segregation analyses, fitting different statistical models corresponding to various patterns to investigate the transmission of genes in families with reading disability. Some observers have concluded that familial dyslexia is transmitted in an autosomal (not sex-linked) dominant mode (Childs Finucci, 1983; Hallgren, 1950), whereas others have found only partial (Pennington et al.,1991) or no support for an autosomal or codominant pattern of transmission. These findings were interpreted as suggesting that specific reading disability is genetically heterogeneous (Finucci et al.,1976; Lewitter, DeFries, Elston, 1980). In here, Quantitative trait loci (QTL) mapping also has been applied (Cardon et al., 1994;Fulker et al.,1991) in order to localize individual genes that contribute to the development of dyslexia. 2.4 Genetic Localization   Ã‚  Ã‚  Ã‚  Ã‚  The researchers passionately set an ultimate goal of genetic study that is to locate and isolate the responsible gene for dyslexia. Once the genes responsible for dyslexia is located, the protein product encode by the gene may permit a physiological explanation for its role in normal processes or diseases and finally contributed to a gene therapy for dyslexic. However, some researchers like Snowling (2000) consider the location of genes is a wide goose chase. The human genome has a rough estimation of about 35 000 genes which distributed over 3 billion bp of DNA and half of them is related to brains. Even when researchers limited the number of candidate genes to screen by using different biological hypotheses, they still need to work with thousands of genes. Thus, considering the risk of failing to match any given hypothesis, researches adopt the linkage and association analysis these two types of mapping strategies. The principle underlying both genetic linkage a nd association mapping is to test for non-random relations between phenotypic similarity across many individuals and haplotype sharing between them. With more generations the analysis become more powerful and accurate because each meiosis provides another opportunity for spurious genotype-phenotype relations to decompose. Linkage analysis refers to the analysis of individuals for whom family relations are known, whereas association analysis is used for large samples of unrelated individuals. Now, linkage analysis is generally less effective than association analysis in detecting genotype-phenotype relations within a study sample size. However, linkage mapping can be done with much fewer genetic markers and is hence easier to use in practice than association analysis. Genome-wide linkage can be carried out by analysis of about 400 highly polymorphic DNA markers. By contrast, association mapping has the power to focus on the specific causal DNA variants that influence phenotype variab ility but in most case it must use much more times that use to analyse DNA polymorphisms then linkage mapping used.   Ã‚  Ã‚  Ã‚  Ã‚  Using current molecular techniques of linkage analysis to carefully study selected family trees of dyslexic individuals in which developmental dyslexia reoccurs in different generations, some early results showed that a major gene for dyslexia was located on the short arm of chromosome 15 (Pennington et al.,1991;Smith, Pennington, Kimberling, Ing,1990). Fulker and his colleagues in 1991 replicated the same result of chromosome 15 though selecting a sample of siblings with reading problems in the study of original extended-family. Others like Lubs in 1991, Rabin in 1993 and Cardon in 1994 did not find the same results.   Ã‚  Ã‚  Ã‚  Ã‚  From a recently review of genetic study of dyslexia, we can see that the candidate genes DCDC2 the double cortin doman containing protein 2 and K1AA0319 show strongest links to the dyslexia among severely affected individuals. However, the candidate genes chromosome 15 and ROBO1 roundabout Drosophila Homolog of 1, which were identified through breakpoint mapping in Finnish patients, seem to be less involved in the development of dyslexia across different populations. However, their research is limited to a few families in the Finnish population and to date, no specific cognitive processes are known to be influenced by the proposed susceptibility genes. Some studies have already started to include neurophysiological and imaging procedures in their phenotype characterization of patients. The molecular genetic studies conducted so far have not considered gender-specific genetic effects. A satisfactory power to detect such effects can be provided only when gender is t aken into account during the analysis of results, and this should be a feature of future studies (Schumacher et al, 2008) 2.5 Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Although, scientific research has yet to prove that dyslexia is a gentic disorder, many researchers and evidence have show that it is a high possibility. In my opinion, dyslexia is a genetic disease and its symtoms can be aggravated or mitigated by the environment. Nevertheless, more research into the correlationship of the genetic factor and the environment needs to be conducted to verify this claim. Reference: Beaton,A.A(2004).

New Leadership in Indonesia and Singapure Essays -- International Gove

The emerging globalized world brings with it new global threats. Various forms of advancement have made the threat of terrorism a global threat. As a result, leaders of democratic states have been forced to work together to contain such threats. This paper examines the extent to which the Indonesian leadership transition from 2004 to 2009 affected security policy relations with Singapore. First, this paper takes a brief look at the new leadership transition of Indonesia and Singapore in 2004. Second, this paper examines whether the new leadership was able to strengthened regional security through the Association of Southeast Asian Nations (ASEAN). New Leadership in Southeast Asia The year 2004 was of significant change not only for Indonesia, but also for Singapore. Both, Indonesia and Singapore, went trough a leadership change in 2004, which allowed them to realign their relationship and interest in the region. On August 12, Lee Hsien Loong was sworn in as Singapore’s third prime minister since independence. Lee Hsien Loong preceded Goh Chok Tong’s 14-year leadership. Lee had long been expected to have some sort of leadership because his father, Lee Kuan Yew, was Singapore’s first prime minister. More notably on October 20, Susilo Bambang Yudhoyono, was sworn in as Indonesia’s sixth president since independence. Mr. Yudhoyono was the fourth president in six years, but was the first directly elected president since the fall of President Suharto in 1998. The leadership transition of 2004 is crucial to understanding foreign relations between Indonesia and SIngapore because it laid the platform from which they could renew, strengthen, and expand their regional ideals.
