Dyscalculia Wheres The Difficulty Education Essay

Dyscalculia Wheres The Difficulty Education EssayMathematics is a subject that is challenging for almost all prentice, during all the years of education. However, at that place are a great add of pupils that experience this challenge, in an even worse degree. These bookmans piss to deal with a hindrance called, dyscalculia. Dyscalculia is a specific culture difficulty, which characterises a occur of people, who face severe difficulties in mathematics, and it is hunting expeditiond by a combination of biological, environmental and cognitive factors. The centralize of this essay, testament be on explaining in more detail, twain specific difficulties that are connect to dyscalculia. These difficulties are, the numerousness difficulties, which are raw materialally difficulties in understanding the most basic principles of mathematics, and the difficulties with number impact and calculation, which are related to the way unmarrieds, process the song, in mold to make ma thematical calculations and solve arithmeticalal tasks.A new phenomenon has displace the attention of researchers in the reach of culture difficulties, the last few years. This phenomenon is associated to the area of mathematics, and specifically, to the difficulties that learners have in the particular area. A great number of pupils have difficulties in understanding the manifold supposition of mathematics, something that does non necessarily mean that these difficulties are caused by a cultivation dis major power. However, in that location are some(prenominal) learners that have an organic difficulty in Mathematics (Reid, 2003, p. 252), a difficulty that is related to a specific graphic figure of accomplishment difficulties, which is called dyscalculia.Dyscalculia can be defined as a condition that affects the efficiency to acquire arithmetical skills. Dyscalculic learners whitethorn have difficulty understanding simple number concepts, lack an intuitive grasp of n umbers, and have problems learning number facts and procedures. Even if they produce a correct answer or use a correct method, they whitethorn do so mechanically and without effrontery (DfES, 2001). In other words, learners, that are dyscalculic, may have difficulties, not only in the procedures that are important in solving a mathematics problem, simply also they may have difficulties in understanding the basic notions of mathematics, such as what does the magnitude of a number represents or what the maths symbols signify. Therefore, the difficulties that dyscalculic learners face, in the area of mathematics, can be rightly considered as more severe than the difficulties that pupils, who dont have a specific learning difficulty, face in maths.Regarding the causes of dyscalculia, there awaits to be a variety of biological, environmental and cognitive factors that lead to this learning difficulty. In particular, a study by Shalev et al. (2001) revealed, that children, who have sib lings with dyscalculia, are at a very(prenominal) mellowed risk of becoming dyscalculic, in comparison with the general population. This study supports the idea that was firstly introduced by Kosc (1974), which proposes that dyscalculia is related to genetic factors. This idea is also supported, by a research with monozygotic and dizygotic twins, which revealed a percentage of 58% and 39% respectively, between the siblings, in the emergence of dyscalculia (Alarcon et al., 1997).In addition to this, there also see to be some differences between dyscalculic individuals and individuals who dont have a difficulty in maths, in the way their brain functions, during mathematical procedures (Shalev and Gross Tsur, 2001). According to several researchers (Levin et al., 1996 bill, Levy Reis and Grafman, 1999), who studied the brain activity of two dyscalculic adults during arithmetic affect (Shalev and Gross Tsur, 2001, p. 339), there seems to be a unilateral activation of the frontal and parietal areas of the left(p) hemisphere of the brain and also a deficiency in the parietotemporal region of the specific brain hemisphere, in dyscalculic individuals. On the contrary, individuals, who dont have a specific learning difficulty, during mathematical procedures, have a bilateral activity on their prefrontal and inferior parietal cortices (Rueckert et al., 1996 in Shalev and Gross Tsur, 2001, p. 339) or else than a unilateral activation. ace cannot be genuine though how accurate is this fact about dyscalculic individuals, because the studies, that took place in order to examine the brain differences of dyscalculic individuals in comparison with the general population, had a sample of only two people with dyscalculia, who were adults. This small sample may not be very representative of the dyscalculic population in general, and thus the innuendo that there are differences in the brain activity of dyscalculic individuals, in comparison with individuals without m aths difficulties, during mathematical procedures, may not be factual and may requirement further examination.Furthermore, there are several researchers, who dont believe that dyscalculia, is a learning difficulty that has a biological basis. They consider a number of environmental factors to be more accurate in explaining the nature of dyscalculia (Shalev and Gross Tsur, 2001). Specifically, they believe that factors, kindred not having the opportunity for a proper education (Miller and Mercer, 1997 Gifford, 2005) or not macrocosm confident about your mathematical skills (Gifford, 2005), is the reason why several learners have dyscalculia. However, whizz cannot be absolutely sure that the difficulties, an individual has in maths, because of these factors, could truly cause dyscalculia or if they just characterise an average person, who has several difficulties in maths which can be reduced by improving these factors. Maybe further research, which leave alone examine if dyscal culia stays persistent even after improving these factors, could solve this reflection.Another environmental factor, which may lead to dyscalculia, is the anxiety that is generated to the learner, because of maths (Ashcraft, 1995). According to Ashcraft (1995), maths anxiety can cause dyscalculia, because learners with this type of anxiety tend to feel really nervous when they have to deal with maths, something that makes them to do mathematical calculations really quickly. Therefore, the learners, because of their recklessness in making mathematic tasks, they may have low per figureance and inaccurate results in mathematics, something that could be considered as dyscalculia or it could make the situation for a dyscalculic learner even worse (Ashcraft, 1995). Also, maths anxiety could lead to low self confidence. Still, it is more possible that maths anxiety worsens and not causes dyscalculia or math difficulties in general, because if dyscalculic learners are forced to make arith metical procedures hastily, then they probably pull up stakes make more mistakes or they wont be able to solve a maths problem at all, because of the pressure they might feel. Furthermore, maths anxiety is something that all students and not only dyscalculic students may experience at some point, as a result of the complex nature of mathematics, and whence its causal role for dyscalculia is questionable. Overall, one may assume that maths anxiety is not necessarily a causal factor for dyscalculia, plainly it is a characteristic that a dyscalculic learner could present.Regarding the cognitive factors that are responsible for dyscalculia, there seems to be a belief that a dysfunction on the visuospatial abilities or the verbal and auditory comprehension abilities, of an individual, can cause dyscalculia, as well as other cognitive disabilities (Rourke, 1993). In addition, several other researchers (Geary, 1993 Koontz and Berch, 1996) believe that problems with the working memory, c an also lead to dyscalculia, because it affects the effort of learners in performing mathematical procedures. According to a research by tabernacle and Sherwood (2002) though, children with dyscalculia didnt have any differences in comparison with children without dyscalculia, in any of the tasks that measured their working memory, and also a correlation between the working memory and the arithmetic ability measures, was not found. Therefore, it is not certain if working memory difficulties have a causal role in dyscalculia or if they appear at the aforesaid(prenominal) time with the difficulties that are linked to dyscalculia (Butterworth, 2005).Overall, a combination of all the factors, that are considered to play a causal role in the development of dyscalculia, may illuminate in a better way the concept of dyscalculia. This is because, dyscalculia seems to be a disability that is more possible to be generated by a great number of factors, just like dyslexia (Frith, 1997), rathe r than by only one, and therefore, it could be better understood if it was seen as whole. That is, to be seen from all the human faces that could generate it, rather than from one aspect only.A better understanding of dyscalculia may also arise by examining the difficulties that are linked to it, and not only be examining the causes of it. Specifically, there appear to be several difficulties that can be identified on dyscalculic learners, difficulties, which in a way, are connected with each other.These difficulties have to do, with the way learners comprehend mathematics from their simplest form to their most complicated one. In particular, they have difficulties with understanding arithmetical concepts, like the numerousness of a number that refers to understanding the magnitude of a number, with the processing of mathematical facts and the calculation of them, which refers to how a learner processes the numbers and the maths symbols that he sees in order to solve a task, and also with difficulties that may be associated with other learning difficulties, such as dyslexia and ADHD, because of the high co morbidity there is between dyscalculia and these two learning difficulties (Shalev and Gross Tsur, 2001 von Aster and Shalev, 2007). For example, in the case of co existence of dyscalculia and dyslexia, the learner has maths difficulties that are related to language, such as reading mathematical problems and solving maths exercises following the correct sequence (Reid, 2003 Bennett, 2006). In the case of dyscalculia and ADHD, a possible difficulty that a learner may have, is not being able to finish a maths task, because of the lack of concentration he may present, something that unremarkably characterises learners with ADHD. This difficulty may also be present to dyslexic learners as well, because of the high co morbidity there is between dyslexia and ADHD, and therefore a learner may have dyscalculia, dyslexia and ADHD concurrently (von Aster and Sha lev, 2007). From this, one can assume that there are cardinal categories of dyscalculic learners learners with dyscalculia alone, learners with dyscalculia and dyslexia, learners with dyscalculia and ADHD, and learners with dyscalculia, dyslexia and ADHD.Even though the issue of the difficulties that a learner may present, because of the co morbidity between dyscalculia and these two other specific learning difficulties, seems to be really exciting and interesting, this essay will focus on the difficulties that characterise learners with dyscalculia alone. Specifically, it will focus on the difficulties that dyscalculic learners have with numerosity, number processing and calculation of mathematical procedures, rather than on the difficulties that result from this co morbidity.In particular, the first difficulty mentioned above, which is numerosity, refers to the abstract form of numbers, which reveals their magnitude (Butterworth, 2005), and it should be the first thing that learn ers should learn, in order to be able to understand mathematics. As Butterworth (2005, p. 3) indicated, numerosity can be the basis of arithmetic. The numerosity refers to an abstract type of numbers, because it is possible for numbers to be arranged in divers(prenominal) sets that can be delineated by different parts, which may have abstract or concrete substance, like straws, sticks, sounds etc. (Butterworth, 2005, p. 3). In addition, when several parts are being assemble in a specific set to form a number, something that represents the numerosity of this set, the learners can easily understand them, in comparison when they see these parts (e.g. dots on dice) in a different order (Mandler and Shebo, 1982). Therefore, numerosity is significant in learning and understanding the numbers, and what these numbers represent, especially when it is presented in specific groups.According to Butterworth (1999), there are four principles that a learner should follow in order to comprehend what numerosity is. Firstly, he must(prenominal) know the one to one concord principle (Butterworth, 1999 in Butterworth, 2005, p. 4), which refers to the ability of a learner to recognise when the numerosity of two sets of numbers is the said(prenominal), by examining the parts of each set which must liken to each other (Butterworth, 2005). In other words, in order for two sets to have the same numerosity, they must be constituted by exactly the same number of parts. Secondly, it is important for the learner to understand that numerosity is a variable and not a fixed concept and that different sets may have different or the same numerosity. Thirdly, the learner must have in mind that numerosity can be abstract, and therefore the sets may be represented not only by concrete things but by invisible, abstract things (Butterworth, 1999 in Butterworth, 2005, p. 4) as well. Finally, it is important for a learner to be able to identify numerosities of sets of four objects the most, w ithout needing to count them verbally. One can suppose that these principles are truly essential in order for a learner to be able to understand the complex meaning of numerosity, because in fact, these principles compose the concept of numerosity. Therefore, by being able to comprehend these aspects, a learner will be able to understand numerosity as well.Regarding the abilities that a learner must have, in order to have an appropriate understanding of numerosity, Piaget (1952) talked about ternary basic abilities. The ability to reason transitively, the ability to understand the stability of the number of items in a set, and the ability to recognise the abstract nature of the items that form a set despite their personal characteristics, like their colour or shape (Piaget, 1952 in Butterworth, 2005, p. 4). Specifically, the first ability refers to logical calculations that a learner can make, after examining several facts. For example, if there are three items, from which the two have the same size and the third is smaller, then the learner must be in position to identify that the third item will be smaller not only from the first item, but from the second item as well. The second skill that should characterise a learner, in order to possess the idea of numerosity, is to know that the number of items in a set will not change if there is a modification in their sequence, pull out if an item is removed or added to the set. The third ability, is relevant to the suggestion made by Butterworth (2005) regarding the abstract character of numerosity and also the one to one understanding principle, because it has to do with the fact that the characteristics of the items of a set cannot affect its numerosity, and therefore it is possible, two sets that are structured by different items, to have the same numerosity.The principles, mentioned by Butterworth (2005), and the abilities, mentioned by Piaget (1952), about the comprehension of the concept of numerosity, ma y be affected in dyscalculic children, because these children have already problems in understanding the general idea of numerosity (Butterworth, 2005). Specifically, children with dyscalculia seem to have difficulties in comparing the magnitudes of several numbers (Geary, Hamson and Hoard, 2000) and also in counting tasks (Koontz and Berch, 1996), something that could lead to the conclusion, that these children have numerosity difficulties, as numerosity is the basis of this type of abilities.Regarding the counting skill, in order for a child to be able to count, he must firstly know the counting words, then he must connect each counting word with only one object, and finally he must have the awareness that, the last counting word he says, is the total number of all the things in a group that he counted, something that basically is the numerosity of the group (Butterworth, 2005). These three characteristics represent the three principles, which were suggested by Gelman and Galliste l (1978) to be essential for the ability to count, and they are called, the stable order principle, the one to one principle and the cardinal principle, respectively (Gelman and Gallistel, 1978 in Butterworth, 2005, p. 7). Two other principles were indicated by Gelman and Gallistel (1978 in Butterworth, 2005, p. 7) as well, which are the abstractness and the order irrelevance, and refer to the ability to recognise the abstract nature of numbers, something which was noticed by Piaget (1952) as well, and the awareness that the order, in which a learner starts to count the items in a group, is not important, as long as he counts each item only once. The principles indicated by Gelman and Gallistel (1978), depend on the principles of numerosity and therefore, in order for a learner to encompass these principles, he must first encompass the idea of numerosity (Butterworth, 2005)A dyscalculic learner may have difficulties with counting, because as it was noticed by Geary (1993) and Koo ntz and Berch (1996), dyscalculic children may have several difficulties with their working memory, and therefore they will find it difficult to count a large fall of objects. This is because, they probably wont be able to maintain in their memory the number of the items that they have already counted, in order to count the rest of them and therefore to find the total number of the items. This difficulty seems to be associated with the third principle, which was indicated by Gelman and Gallistel (1978), because if a learner is not able to remember the items that he counted until one point, he may then consider as the last number of a set, which will represent the total of the items as well, an awry(p) number. In addition, sequent and visuospatial difficulties (Bennett, 2006 Rourke, 1993), that usually characterise dyscalculic learners, may also affect a dyscalculic learners skill to count, because he may find it difficult to count an item only once, following the one to one pri nciple (Gelman and Gallistel, 1978 in Butterworth, 2005, p. 7), because of the confusion he may have about the sequence of the items. Therefore, one can assume that this kind of difficulties, affect not only the ability of a dyscalculic learner to count, but his knowledge about numerosities as well, as numerosity is essential for counting.These particular difficulties, can lead to the demeanor of other maths difficulties as well. These difficulties have to do with the number processing and calculation abilities. According to McCloskey, Caramazza and Basili (1985, p. 173), the number processing skills, have to do with the ability of a learner to understand and produce numbers, and the calculation skills, refer to the facts and procedures that are necessary in making mathematical calculations. In particular, McCloskey et al. (1985, p. 173) referred to two different systems that are related to these skills, which are the number processing system and the calculation system.The number processing system, is composed by two subsystems, the number comprehension subsystem, and the number production subsystem (McCloskey et al., 1985, p. 174). These subsystems accommodate two units, the Arabic numbers unit and the verbal numbers unit, which have to do with the appearance in which the numbers are presented, either in human body or in oral / written form correspondingly. Each of these units is divided into a lexical processing and a syntactic processing element (McCloskey et al., 1985, p. 173). These two elements are associated to the ability, to recognise each part of a number (lexical processing) and to the ability to recognise, according to its elements, the specific number (syntactic processing). For example, if the number 516 is presented to a learner, either in Arabic or verbal form, he must be able to recognise the meaning of each number of the set, something that has to do with the lexical element, and to understand that, with this order, the specific numb er, will have five hundreds, one tens and six units, a procedure that depends on the syntactic element (McCloskey et al., 1985).Dyscalculic learners may present difficulties on one of the subsystems of the number processing system and consequently, on one of the units or the elements that these two subsystems include. Specifically, a research by Benson and Denckla (1969) with one dyscalculic individual, revealed a difficulty in the production of numbers of twain forms and in the lexical processing of numbers, whereas the individuals comprehension and syntactic processing components, were fine. In addition, McCloskey et al. (1985) noticed in two dyscalculic individuals, that one of them had difficulties in distinguishing the magnitude of two numbers when those numbers were presented verbally, and the other individual had difficulties when the numbers were presented digitally.Even though the difficulties indicated by Benson and Denckla (1969) and McCloskey et al. (1985) are difficul ties that a person could notice in dyscalculic learners, one cannot be sure about the reliability of the results of the specific studies, because the sample they used was really small and because the studies took place several years ago, and consequently the particular results, may not be adequate for today. However, some of these difficulties, like in the case were the individual had to compare two numbers about their magnitude, seem to be associated to the concept of numerosity mentioned above, and therefore these difficulties, may be sufficient in characterising dyscalculic learners.Regarding the calculation system that was indicated by McCloskey et al. (1985), it is constituted by three units and it depends in some point on the number processing system. These three units, work independently from each other, and have to do, with the way the maths symbols, or words, are processed, with the arithmetic facts, and with the calculation procedures (McCloskey et al., 1985, p. 179).The first unit refers to the ability of a person to understand what calculation he must do, in relation to the maths symbol or word that is presented to him (McCloskey et al., 1985). For example, when a person sees the symbol x or hears the word multiply, he knows that the operation he must do, is multiplication. However, a dyscalculic learner may confuse the arithmetic symbols and, even though he may know the right answer, he may answer incorrectly. Something similar happens when the arithmetic symbols are presented with words, but with the difference that when maths problems are related to language, there is a belief by several researchers (Reid, 2003 Bennett, 2006) that these problems are more associated to maths dyslexia rather than to dyscalculia, and therefore this suggestion is more related to the co existence of dyscalculia and dyslexia, rather than to dyscalculia itself. Overall, difficulties with the arithmetic symbols or words may be generated by visuospatial (Rourke, 1993) or language difficulties (Reid, 2003 Bennett, 2006) that sometimes characterise dyscalculic learners, thus dyscalculia can be characterised by difficulties with the operational symbols as well.The second unit is related to the ability of an individual to maintain and retrieve from his long term memory, the correct answers of specific mathematical facts (McCloskey et al., 1985). An example of arithmetic facts, is the knowledge of a learner about the times tables. This unit is independent from the first one, because a learner may have difficulties in recognising the operational symbol, but his answer may be correct when another symbol is used, or he may do the right operation but retrieve the incorrect arithmetical fact. For example, Ferro and Botelho (1980), noticed in a dyscalculic learner, that kind of of adding two numbers when she saw the symbol +, like for example 9 + 2, she multiplied them and answered 18 instead of 11. In addition, McCloskey et al. (1985) observed that a dy scalculic individual couldnt retrieve the correct answer in a case of multiplication, even though he understood the concept of multiplication adequately. Several dyscalculic learners may face difficulties in learning or in retrieving arithmetical facts (Russell and Ginsburg, 1984 Kirby and Becker, 1988 Geary, 1993 Temple, 1994 Ginsburg, 1997 Jordan and Montani, 1997 Geary and Hoard, 2001 Shalev and Gross Tsur, 2001), and a reason for this may be the fact, that some dyscalculic individuals have difficulties with their working memory (Geary, 1993) or with their long term memory, as well (Reid, 2003). This, may limit the ability of a learner to maintain or to retrieve a mathematical fact from his long term memory, and therefore to cause him difficulties that characterise dyscalculia.The third unit of the calculation system refers to the abilities that learners have in making mathematical calculations (McCloskey et al., 1985). These abilities are related to the way learners comprehen d and learn the procedures of executing math calculations, something that in dyscalculic learners is usually impaired (McCloskey et al., 1985 Temple, 1994 Butterworth, 2005). For example, dyscalculics may have difficulties in completing procedures in which they have to carry a number, whilst doing a maths operation, because of the fact that they may put the number on the wrong place, something that leads to wrong calculations. Also, they may have difficulties with procedures, in which they must do two different mathematical operations at the same time. Both of these difficulties, may be the result of sequential difficulties (Bennett, 2006), or again of memory difficulties (Geary, 1993 Reid, 2003), that are considered to be related to dyscalculia, and therefore dyscalculics may face this kind of difficulties, as well.The specific model for number processing and calculation abilities, even though it was created several years ago, is in general lines, sufficient in explaining this type of abilities, in relation to dyscalculia. In addition, the aspects described in the model, seem to be have a common ground with the numerosity, described above, regarding the causes of the difficulties that dyscalculics may present. Therefore, one can assume that similar methods can be used, in order to help a dyscalculic learner to limit his difficulties with numerosity and with number processing and calculation abilities. Specifically, several researchers suggest that multi sensory methods (Bennett, 2006) in combination with the learners learning styles (Chinn, 2001 Marolda and Davidson, 2000 Sharma, 1989) can be vital in teaching and helping dyscalculic learners. This is because, by focusing on the way that an individual learns the best, one can help this individual to grasp the concepts of numerosity and of number processing and calculation, in the greatest extent, and by using multi sensory methods, he will make the learning for the individual to be fun, less stressing and m ore motivating. With this way, the learner will probably feel more confident, and therefore more determined to improve his difficulties in mathematics.In conclusion, dyscalculia is a very recent issue in the area of learning difficulties, and

The Arguments For And Against Globalization Economics Essay

The Arguments For And Against orbicularization Economics EssayGlobalization is a modern phenomenon, which undersurface be analyze from various points of view. Roughly, we might say that globalization is integration of regional economies, societies and cultures in a globe-spanning network of communication and trade. This term is part of a historical figure out of capitalism which is a new international order in the context of a single humanness.Globalization is sometimes use to refer specifically to frugal globalization. This topic go out be developed along the essay. However, as once was expressed by the ex-secretary of the United Nations Brutos Gali, thither is no only one globalization, there atomic number 18 many globalizations such us technological, sociocultural, political, biologicalAn example of that not only the economic globalization exists is the creation of the International Penal Court, since the human rights atomic number 18 starting feeling the effects of the g lobalization and it is necessary uniform and universalize the recognition of the fundamental rights of the citizenship.Globalization overly refers to a process of interaction among societies and local cultures in a global culture to what we would call sociocultural globalization.Different definitionsThe word globalization is delineate by contrasting authors, official institutions and dictionaries check to their point of view. Therefore, there is not only one precise meaning of this term universally accepted by everybody.On the one hand, United Nations (UN)1has defined it as an event, unavoidable in our history. It makes one world through the exchange of goods, increases, culture, fellowship and culture. This is a result of the step forward in the field of communications, transport, engineering science and industry.According to the World Bank Group (WBG)2, the most utilized meaning for globalization is an intercontinental economic activity, which has increased sharply. In th is activity they include hostile Direct Investment (FDI), International Commerce and Capital Flow.However, the International Monetary Fund (IMF)3has combined both the United Nations and the World Bank Groups definition. It besides negotiation about globalization in terms of FDI, Capital Flow, International Commerce and the surprising evolution of communication and technology. Further more, IMF specifies that sometimes globalization makes it necessary for the workforce and knowledge to discombobulate to move to another country.But, these kinds of institutions are not the only ones who want to give their own definition of globalization. A wide range of authors have habituated their opinion on the topic.For example, David Dollar4, in an interview published in the World Bank Group Web, said that the economic globalization, or as he would rather use, the economic integration takes place when a country reduces or eliminates the commercial barriers such as custom duty, and they accept investments and trade from the rest of the world.However, Leslie Sklair5thinks that it should be seen as a new phase of capitalism, one that transcends the unit of the nation-state. His college, Anthony Giddens6, does not think in the same way as him. In this case, he negotiation about globalization as a renewing in the global market, the evolution in the communication and trade between nation-states in physical commodities, information and currency.Evolution from two different points of viewTheodore Levitt7was the creator of the word globalization. He used it for first time in his book called The Globalization of Markets to describe the transformation of the international preservation which had been taking place since 1960.However, its evolution is not clear enough. any(prenominal) people say that it started in 1980s and others are in prefer of 1870s. But in either case, the bases of globalization are three specific ideas, according to the Washington Consensus a severe fiscal s ystem, privatization and the relaxation of the restrictions on economy8.The World Bank Group talks about four steps in Globalizations evolution. Whereas, Leandro Snchez Zepeda, in his doctoral thesis, explains that there are five different stages. I do not have enough knowledge to decide which is more appropriate, so in the following paragraph I am issue to give details about the development of both thoughts.According to the WGB9, these are the stepsFrom 1870 to 1914 this period was characterized by the step forward in transport and the excreting of commercial barriers. The amount of exports augmented almost 8% and 10% of the total population moved to another country.From 1914 to 1950 the situation was as before 1870, marked by protectionism.From 1950 to 1980 during those years, the process evolved to an economic integration between rich countries. Moreover, Europe, North America and Japan opened their markets.From 1980 until 2009 in this time, manufacturing increased to 80% cosm opolitan. Some countries, such as Brazil, India and Vietnam, remedyd their international commerce and the globalization made developing countries improve.On the other hand, Leandro Snchez Zepeda10has put forward a different opinion in his doctoral thesisFrom 1870 to 1913 this period was marked by a peak in commerce collectible to an increase in capital and labour force.From 1913 to 1950 callable to the Great Depression, the First and the Second World War international commerce decreased.From 1950 to 1973 thanks to the Bretton Woods system, global integration was strengthened.From 1973 to 1990 during these years the amount of public companies which became hidden increased, the financial system started to be more open to the world, communication and transport advanced and it became international.From 1991 until today there are more free-trade areas, such as ALADI, NAFTA and ASEAN, and the economic integration has become stronger. In contrast to previous periods, the workforce move s less and capital and information are crossing borders.GLOBALIZATIONGlobalization itself is a consecutive and dynamic process that challenges the laws of the countries in how they regulate the operation of enterprises and economic behaviour of individuals at the international level, who can give employment to workforce unemployed and also benefit from remaining irregularities and weaknesses in a particular country.It is a complex phenomenon therefore it should not surprise us that it causes different reactions in different individuals or groups. Some consider that threatens the framework of the nation state, national identity and the modern concept of democracy. For some, it promises a new era of riches for all, for others, it is the seduction of a consumerism that will bankrupt morally and economically the majority.In favour of globalizationWhy economic globalization is a good system? Advances in communication and shipping technology, combined with free-market ideology, have give n goods, services and capital unprecedented mobility. For example, Northern countries want to open world markets to their goods and take advantage of abundant, cheap labour in the South. To do this, these countries use international financial institutions, such as, the International Monetary Fund and the World Bank Group, and regional trade agreements11to compel poor countries to mix in by reducing tariffs, privatizing state enterprises and relaxing environmental and labour standards.Globalization is a phenomenon that is merchandiseant to the develop of the economy in every country, due to the universal opening of markets for goods and capital suggests the end of trading blocs, regional treaties and economic independence of countries but also facilitates the ability to solve economic needs that local players have been unable to satisfy. It makes easy the commerce between different countries and decreases the difference between developed and underdeveloped countries.Some factors i n favour of globalization areGlobal economy and market, which can lead to a better utilization of resources.Greater ability to maneuver compared to fluctuations in national economies.New opportunities of develop markets.Using economies of scale, it can reduce cost.International cooperation.Growth and mergers between companies.Privatization of public companies.International financial deregulation.Development of doer of communication and transport.The free movement of capital allows a more efficient allocation of global savings and provides to emerging economies the resources to develop and promote the consolidation of a sustained and balanced growth.Globalization opens up opportunities for developed economies to improve their efficiency and productivity and allows economies in developing to improve the living standards of its population.Against of globalizationWhen globalization was defined, it tried to minimize the impact of negative points and reinforce positive points.Some factor s against globalization areLack of control over markets and multinational enterprises.Increased economic social and territorial imbalances.Concentration of richness and increased social inequality.Non-fulfilment of nominal labour standards. Full employment, a priority until recently, was postponed. The work has to behave as a commodity, subject to the laws of supply and demand and the output signal needs, without laws that safeguards smooth minimum rights. impairment to the environment.Threat to biodiversity and cultural heritage.Dominance of financial-speculative economy over real economy.Increase exploitation of child labourControversyThe liberalization of international trade means more economic growth and welfare, such as the example of China, where foreign capital has invested heavily and the country has emerged remarkably by the effect of globalization. But if we go to Africa, we can see that its people are sinking ever deeper into poverty and degradation of economic, social and political life. There, no one invests and the one thing that Africa is used by Occident is for the arms business and to recover the debts they owe to developed countries.It is true that globalization encourages free trade among countries, but there are also negative consequences because some countries try to save their national markets.Companies are buying goods and services from foreign countries. Workers, who were sacked, are forced to work into the service sector, where wages and benefits are lower. This has contributed to the deterioration of the middle class, who have been relegated to lower positions. People in the lower class have to make more efforts to climbing out of poverty due to the absence of the middle class as a stepping stone.THE PROBLEMS OF GLOBALIZATIONGlobalization is the shortest and most viable way for the developing world to achieve political, social and rational modernity. Globalization is said to be the best and most effective means for the developing w orld to achieve comprehensive development, because it is the sole way to progress for this world economically. Changing the world to the better is through applying globalization.There are problems in the process of globalization if other countries produce goods better than other, maybe a cluster of citizens from this last country will be sacked if one state collects less tax, companies could go there to get more profit. The process of globalization entails adjustments in national and international economies, to which countries must adapt.Income distribution in many cases goods are produced in a nation through the importation of them is less restricted. The removal of import barriers may cause a substitution of goods produced within the country by others imported. This way, domestic manufacturers are affected. However, the elimination of trade barriers can make a product cheaper, which is an advantage for consumers because they can buy more with the same funds.On the other hand, glo balization promotes the concentration and the emergence of large multinational companies. The possibility of selling its products worldwide and reduce production costs through exploitation of economies of scale, cause that small businesses reducing their sales potential. This can result in the reduction of global contender and that one or a few companies dominate the market.Evade national law the possibility of settling in any country encourages companies to look for those where production costs are lower. As the laws of many countries may increase costs for businesses, they seek countries which have less legal regulation. In fact, there are territories in which companies dont pay taxes for the profit. They prefer to settle there, due to they can pay higher returns to their shareholders.

The Significance of the Host/Guest Relationship in The Odyssey Essay

The Odyssey is an epic poem attributed to the now-famous Greek poet, Homer, written approximately in the early sixth century B.C.E. The poem shares the tale of the wily adventuring solider, Odysseus, return from the Trojan war to his wife and home in Ithaca. The poem details his misadventures, the efforts of his son, Telemachus, to generate him, and revenge on his wifes suitors. While many themes run through this poem, the most prevalent is that of hospitality. The Host- node relationship is significant in the Odyssey as it acts as one of the briny thematic devices used by Homer and examples of good hospitality versus bad hospitality and their results serve as the important plot elements throughout the tale.The Host/Guest relationship, also known as the Guest-Friendship relationship was a complex relationship based on a series of ambiguous hospitality laws. Guest-friend...is the English interpretation of the Greek xenos ...The same Greek word meant stranger, foreigner, and some du rations host, a confusion symbolic of the ambivalence which characterized all dealings with the stranger in the archaic world. The corpse itself involved a few rituals. The host was not to ask the identity of the guest until after they have eaten, bathed, rested and/or received gifts of monetary value. The gifts wide-ranging depending on the seeming status of the guest. Lower class guests received only food, while higher classes received anything from jewels, to weapons to livestock. The Host/Guest relationship is one of the main virtues of the Homeric Greeks. It served as the alternative to marriage in forging bonds between rulers and there could have been no more dramatic test of its value in holding the network of relationships together than just such a cr... ... of either guest, nor host, the system of hospitality served as stability and protection in a time of suspicion and danger.BibliographyBeer, Josh, PhD.

The Rate Law for Chemical Reaction Among Hydrogen Peroxide, Iodide, and

The Rate Law for Chemical Reaction Among Hydrogen Peroxide, Iodide, and AcidTo steady down the run law for a chemical reaction among hydrogen peroxide, iodide and acid, specifically by observing how changing each of the concentrationsExperiment 3 Chemical kineticsObjectives1. To determine the rate law for a chemical reaction amonghydrogen peroxide, iodide and acid, specifically by observing howchanging each of the concentrations of H2O2, and H+ affects the rateof reaction.2. To determine the effects of temperature and catalyst on the rateof reaction.IntroductionGenerally, two important questions may be asked about a chemicalreaction(1)How far do the reactants interact to yield products, and (2) howfast is the reaction? How far? is a question of chemical equilibriumwhich is the realm of chemical thermodynamics. How fast? is therealm of chemical kinetics, the theater of this experiment.In this experiment we will study the rate of oxidation of iodide ionby hydrogen peroxide which p roceeds according to the followingreactionH2O2 (aq) + 2 I-(aq) + 2H+(aq) I2(aq) + 2H2O(l)By varying the concentrations of each of the three reactants (H2O2, I-and H+), we will be able to determine the order of the reaction withrespect to each reactant and the rate law of the reaction, which is ofthe prep atomic number 18Rate = k H2O2xI-yH+zBy knowing the reaction times (t) and the concentrations of H2O2 oftwo separate reaction mixtures (mixtures A & B), the reaction order ofH2O2, x, can be calculated.x = log(t2/ t1) / log ( H2O21/H2O22 )The same method is used to obtain the reaction order with respect to I-(mixtures A & C) and H+ (mixtures A & D).ProceduresPart I) Standardization of H2O2 Solution1. A stand, a burette clamp and a white tile were collected toconstruct a titration set-up.2. A burette was rinsed with deionized water and then with 0.05 MNa2S2O3 solution.3. The peter of the burette was closed and the sodiumthiosulphate solution was pour into it until the liquid level wa s nearthe zero mark. The stopcock of the burette was opened to allow thetitrant to fill up the tip and then the liquid level was adjusted nearzero.4. The initial burette reading was recorded in Table 1.5. 1.00 cm3 of the 0.8 M H2O2 solution was pipetted into a clean125 ... ...te of a reaction byproviding an alternative pathway for the reaction, usually with apathway of lower activation energy than that of the uncatalyzedreaction.There are some improvements in this experiment.First, hydrogen peroxide is unstable, it decomposes to water andoxygen by time. Therefore do the titration as quick as possible.2H2O2(aq) 2H2O(I) + O2(g)Second, the concentration of iodine extend is due to the iodide canbe oxidized by oxygen which promoted by acids. Therefore do thetitration as quick as possible.4I-(aq) + O2(g) + 4H+(aq) 2I2(aq) + 2H2O(aq)Third, as for the human error, the chore can be minimized byperforming the titration by the same person. So, the reading can betaken by the same person an d the colouring material change can be observed by thesame person.ConclusionIn the experiment, the reaction was found to be zero order respect to(H+), it is kickoff order respect to iodide, (I-) , it is first orderrespect to hydrogen peroxide, (H2O2). Hence the rate law is Rate = kH2O2I-.The rate of reaction is increase when the temperature is increase andthe rate is increase when a positive catalyst is added to thereaction.

The Bedroom in The Yellow Wallpaper by Charlotte Perkins Gilman :: The Yellow Wallpaper Essays

The Yellow wallpaper The Bedroom The sleeping accommodation is an overvalued fetish object that nevertheless threatens to reveal what it covers over.

White Attitudes Towards Nature Essay -- Racial Relations, Indian, Whit

In Luther Standing cans Nature and Louis Owenss The American Indian Wilderness, the authors consecrate differences in Indian and white relationships with disposition. They stress how Indians see nature, their balanced relationship with it, and how Indians know wilderness is just a European idea. Though agreeing here, Standing take focuses on how Indians rattling lived while Owens reveals more of both sides and has hope that white realises can shift.Standing Bear thinks the difference in how whites and Indians see nature stems from childhood. He believes Indian children are aware of nature because they have been taught to become conscious of life and spend time observing the wild around them (9). By perceive the world this way, their love and respect for it flourishes (10). He says this appreciation sharply contrasts to ignorant whites who thoughtlessly play as children, ignoring everything but each other, and grow up irrespective the knowledge nature gives, seeing only what th ey can use. He thinks whites are bored with nature because they do not have the Indian point of view (11). The distance whites have from nature harms their relationship with it and humans, making them less compassionate when they do not see mans heart, away from nature, becomes hard (Standing Bear 12).Similarly, Owens says whites see nature differently because of childhood experiences. Instead of growing up daily in nature, white children sporadi entreaty go camping, and thus view nature as a tourist attraction instead of a second home. He states Indians embrace nature because it has a stronger family significance to them that whites do not see. Indians call the Cascades the Great Mother because of stories they have heard growing up, and things like this ca... ...s have led him to think whites will never change and that the two races can not understand each other (12). On the other hand, Owens has hope for whites because he did not grow up with Indian traditions and he witnessed th e U.S. Forest Service protect nature when he was sent to burn the shed. (11).Indians comprehend and value nature more than whites and these authors recognize that. They believe the trouble with white attitudes is they do not truly see nature or form harmonious relationships, and whites think they can be separated from their idea of wilderness. Although Standing Bear is critical of whites and believes they will never change, Owens thinks they will if they continue to redefine how they view nature and try to connect with it. Overall, both authors want whites to respect the Indian way of living with nature and target to be that way also.

Identifying Lesbian and Mother :: Argumentative Persuasive Papers

Identifying Lesbian and MotherIn her 1995 book, On the Outside expression In The Politics of Lesbian Motherhood, Ellen Lewin presents the phenomenon of sapphic women who, through childbirth, gain access to the heterosexual community as an in-group member. At first glance, Lewins observations seem to counterbalance traditional inner(a)/outside ideology, portraying the boundaries of the hetero- and homosexual worlds as permeable rather than rigidly, relationally exclusive. A more exhaustive analysis, namely of the accounts of the women Lewin interviews, serves instead to reinforce wrong/outside construction in relation to self and perceived identity. While the women are allowed into the selective sphere of heteronormality, they do not cross these categorical lines as both lesbian and mother. This paper will argue that the terms lesbian and mother are mutually exclusive, perhaps not in reality, but in the capacities of identity, performance, and location within an inside/outside dy namic. Lewin prefaces her analysis with a glance at the classic Western representation of the lesbian. This depiction focuses on the exclusion of lesbians from typical female roles of gestation and nurturing macrocosm a mother carried an implied notion of heterosexuality, therefore, lesbianism and motherhood cancelled each other out in the popular imagination (107). Indeed, many of the women surveyed shared the sentiment of motherhood as overwhelming and engulfing other dimensions of their livesincluding what they considered the lesbian component (109). While this may be ascribed to the daunting tasks of mothering and childcare, the women pointed to a more self-appropriated explanation as they echoed one other in their tendencies to downplay the significance of their lesbianism in giving accounts of themselves as mothers (110). Simultaneously, these women were rooting themselves more deeply in the heterosexual world and losing ties with the homosexual world. Many of the reports qu ote the lesbian mothers as feeling stronger ties to the world they share with straight women than with other lesbians. Many felt the lesbian community to be unfriendly to lesbian mothers. One cleaning woman was even asked to leave her all-lesbian rap group after her child was born, as her fellow group members believed she was no loner attuned to lesbian issues (124). The question remains as to why straight mothers, as a representation of the larger heterosexual community, would be so quick to ally themselves with lesbians, even lesbian mothers. For a student of feminist theorist Diana Fuss, this coalition seems to threaten the inside (read dominant) status of heterosexual society.
