Analysing Causes Effects And Implications Of Sibling Incest Social Work Essay Essay Example

Analysing Causes Effects And Implications Of Sibling Incest Social Work Essay Essay Example Analysing Causes Effects And Implications Of Sibling Incest Social Work Essay Paper Analysing Causes Effects And Implications Of Sibling Incest Social Work Essay Paper This literature reappraisal focuses on research that is related to sibling incest and discusses the causes, effects and deductions that sibling incest has on the victim, culprit and the household. It focuses on the types of research that is conducted and the failings and strengths of these surveies. It besides discusses farther deductions and suggestions for future research in respects to sibling incest. It is meant as a reappraisal of the types of research and how this affects our positions on sibling incest and ways that we can better future research to assist those that are victims, culprits and impacted by sibling incest. Sibling Incest is a immense tabu in the US and an issue that is mostly dismissed as something that is non experienced by the general population and occurs merely in a really little sum of instances. After reading each of these articles, it has become clear that there is a important deficiency of research sing this peculiar signifier of household maltreatment. Much of what has been researched seems to belie each other and are inquiries sing this concealed tabu continue to travel unreciprocated. When most people in the US think of incest, specifically sibling incest, they seem perplexed as to what causes this desire in people and how this plays out in a household. Sibling incest seems to be considered one of the highest signifiers of maltreatment within a household and demands to be researched so that we may get down to understand the full impacts this has on persons and households. By researching and understanding this maltreatment more thoroughly we might be able to forestall future incest instances and aid victims and culprits recover from such a violent signifier of maltreatment. We might besides be able to come to understand the full impacts of sibling incest and if our positions as a state and our tabu against it holds true. Does sibling incest violate such basic psychological positions and swearing relationships that might damage the victim more than any other type of household maltreatment? Thompson discussed why incest between siblings demands to be studied more than any other country ( 2009 ) . The writer described the sibling relationship in respects to incest and the effects the incest has on the victim and the household as a whole. Thompson sheds visible radiation on the households of sibling incest relationships and different theories that can get down to explicate the household system and household response upon revelation of the maltreatment. The writer examines how blaming plays a portion in the reactions to incest revelation by the household, and how this affects the wellness and well-being of the victim. Thompson describes different get bying mechanisms and the effectivity of group therapy in the lives of incest victims. The writer briefly discusses different theoretical models that might help in work covering with female victims of incest. Thompson focuses on household systems theory and the relationships within the household. A group theoretical account is mentioned as a successful manner to work through incest injury and develop healthy get bying schemes. Short-run and long-run group theoretical accounts are discussed in their benefits and disadvantages that each provide ( Thompson, 2009 ) . Snoging Your Sister The article Kissing Your Sister summarizes a survey performed by three evolutionary psychologists, Debra Lieberman, John Tooby, and Leda Cosmides. The survey sheds light as to what makes people avoid incest dealingss. The survey was performed on 600 people and investigated their household histories and relationships. The survey suggested that there are two chief things that trigger us to avoid sexual relationships with our siblings. These triggers are the sum of clip that the individual spends with the kid s female parent at a immature age and the sum of clip the two spend populating in the same house. Harmonizing to the writers, these trigger two evolutionary procedures that are good to the endurance of worlds. Altruism and antipathy to incest aid persons to last by acquiring along and avoiding possible malfunctions in reproduction. Sibling Incest: Reports from 41 Survivors In the article, the writers discussed a survey that was performed with 41 grownups who experienced sibling incest. The research was done due to a important deficiency of old research in this specific country. Included in the survey were work forces and adult females, culprits and victims. The sample consisted largely of Caucasic propertyless adult females with a average age of 39 old ages old. They asked open-ended and closed-ended inquiries sing the maltreatment, who started it, the continuance, and revelation. The study consequences reported several findings. It suggested that the mean age difference was around 4 old ages with victims being, on norm, around age 7 at oncoming and age 13 at the terminal of the maltreatment. The inquiries investigated several issues included who initiated the maltreatment and the menace of force that is placed on the person. The writers besides investigated other sexual maltreatment experienced by the participants and the environment of the household, including any physical, emotional, and/or sexual maltreatment experienced with other household members and non-family members. Sibling Incest within Violent Families: Children under 12 Seeking Raising In the article, the writer investigates possible causes that might take to sibling incest including violent places, disregard, and a demand for love and raising. The writer suggests that force in the place may act upon a kid s sexual individuality and perchance act upon the desire for incest. The writer defines violent households, the construct of raising, and sibling incest in order to make a image of how they might interact and act upon each other. The writer uses anecdotal grounds to back up her positions that household force may take to a different sexual individuality in the kid and sibling incest desires. The writer explores the procedure kids exposed to violent households might travel through. She recognizes the demand for connexion, comfort and raising that the kid has and suggests that they begin to look for this emotional connexion in their siblings. She investigates the sexual advancement and geographic expedition that a kid goes through from birth to adolescence and how t his might be affected by household force. The writer discusses the possible effects of shame and how this might do a kid more vulnerable to sibling incest. Findingss of each survey Sibling Incest: A theoretical account for group pattern with big female victims of brother-sister incest. Thompson argues that a long-run group theoretical account is best used when working with incest victims. Thompson ends the article forcing for a broader attack when look intoing the lives and injury of incest victims, looking at the manner household kineticss and interactions play a portion in taking to incest. Thompson recommends group therapy as a manner to assist victims experience understood and work through their header accomplishments as a group. Snoging Your Sister The writers interpret their consequences from their survey on sibling incest to propose that the sum of clip the possible incest spouse spent with you in the same roof and being raised by the same female parent, predict the likeliness of incest behaviour. The more clip the stepsibling or sibling does pass in these conditions increase the likeliness that you will avoid incest Acts of the Apostless. They besides suggest that adult females are more likely to avoid sibling incest perchance due to the desire to reproduce healthy progeny. The writers suggest that antipathy to sibling incest is strongest among siblings of the opposite sex. ( Lieberman, Tooby, Cosmides, pg. 1 ) Sibling Incest: Reports from 41 Survivors The writers in this survey were led to believe that the mean age difference between culprits and victims was 4 old ages with the most instances of sibling incest experiences including caressing and holding the sibling s genitalias rubbed on the topic s organic structure. The survey suggests that a bulk ( 68.3 % ) of participants were coerced, threatened or bribed in order to coerce cooperation. ( pg. 9 ) It suggested that more male participants believed the sexual experience was consensual. It besides suggested that more maltreatment ended when the culprit left place, versus the victim. The bulk of participants perceived themselves to be emotionally abused by being ridiculed, degraded or set down, emotionally neglected, or threatened with maltreatment. ( pg. 10 ) The research workers discovered that revelation of sexual maltreatment occurred about seldom. The bulk of participants besides reported holding sexual experiences with other household members. The survey concluded that si bling incest can be durable and often entails intercourse. In most instances the sexual behaviour was coerced in some manner. Parents were rarely cognizant of the maltreatment while it was happening, and factors other than revelation most frequently led to the incest stoping. ( pg. 13 ) . Sibling Incest within Violent Families: Children under 12 Seeking Raising Harmonizing to the writer, the effects of sibling incest can be traumatising as the single enters maturity. The writer believes as a consequence of her anecdotal grounds and researching ideas on sexual geographic expedition throughout childhood development, that the kid s reading of sexual geographic expedition might be altered due to the maltreatment and the kid s hunt for another signifier of raising in their environment. As the kid develops their positions on this will change, in which instance they might see their incest acts as disgusting and no longer normal, therefore the grownup undergoes important psychological hurt. The writer suggests that harmonizing to the determiners theoretical account, a deficiency of societal support and parental handiness will go forth the kid at high hazard for sibling incest, both as a culprit and victim. Strengths/Weaknesses of each survey In the article Sibling Incest: Reports from 41 Survivors, there are so many elements that skew the findings of the research workers. First, the research workers interviewed both culprits and victims, doing the rubric of the article really deceptive. By questioning culprits every bit good as victims, they are skewing the information to stand for either higher or lower per centums in certain countries. The age difference between culprits and victims was skewed because they used all participants informations as stand foring of the victim, and their opposite number as stand foring of the culprit, even though there were several persons in the survey that reported originating the maltreatment. Several other misunderstandings of this information might hold led to skewed findings and misinterpretations of sibling incest. Sibling Incest within Violent Families: Children under 12 Seeking Raising nowadayss some good suggestions and possible thoughts on what might do some signifiers of sibling incest. It presents good anecdotal grounds that might take to really good research surveies that will look into this correlativity in more deepness. However, the anecdotal grounds and the mere sentiments of the writer are non plenty to come to any decisions about the correlativity between household force and sibling incest. It is nt adequate to alter therapy, bar, and intercession in respects to sibling incest. These types of articles are great gateways that lead to farther probes of relationships and causes of many types of household force and go on to be the start of research that has nt been investigated yet. Decision It is clear that there needs to be much more researched in respects to sibling incest in order to understand the full kineticss and deductions of this misdemeanor upon an person. The articles that are mentioned above Begin to turn to these issues, some of which really addressed possible deductions that sibling incest has on persons. However, most of the research was targeted at causes of sibling incest. They all came to similar decisions such as the culprit is by and large about four old ages older than the victim. The lone article that seemed to turn to the deductions of maltreatment on persons was Sibling Incest: Reports from 41 Survivors, and this even was really brief and concise. They suggested that victims might experience a sense of misgiving towards the opposite sex as grownups and experience uncomfortable in sexual relationships. Most surveies performed open-ended and close-ended inquiries on grownups that had experienced sibling incest as kids. Thompson describes different ways to assist victims get by with the maltreatment as grownups by utilizing group therapy and learning get bying mechanisms. The deductions that these surveies hold on farther research of sibling incest are important. Further research should be used to execute different types of surveies and experiments including long-run surveies. This becomes a challenge when normally sibling incest is non disclosed until the victim is an grownup and much clip has passed since the maltreatment. We should besides concentrate our surveies to detect precisely how sibling incest might impact the victims and the households throughout the life-time and in the following coevals. Although some of the research examined was thorough, it is of import that we continue research on this capable affair in order to go confident of the causes and understand the household state of affairss that might take to mistreat. Since some of the grounds is contradictory, it would be helpful to derive more penetration with b etter designed surveies and larger sample sizes. I hope that some of these articles encourage more research to be done on such a hard subject to understand as sibling incest.

Is 'Maurice' a hopelessly flawed text, or a thoughtful adaptation of Essay

Is 'Maurice' a hopelessly flawed text, or a thoughtful adaptation of the novel form to the subject matter and a strong intervention in debates of the time - Essay Example Forster’s autobiographical parallels with Maurice has fuelled debate as to whether the novel was significant as â€Å"a strong intervention in debates of the time† or alternatively a â€Å"hopelessly flawed† text. It is submitted at the outset that neither dogmatic view is entirely authoritative regarding the significance of Maurice and this analysis explore the premise that perhaps the flaws associated with Maurice were a necessary evil in presenting E.M. Forester’s gay ideology. Forster’s self proclaimed significance of the novel as a symbol of the future is juxtaposed with Maurice reflecting on the past4. In the â€Å"Terminal note† to the novel, Forster asserts that Maurice’s escape with his lover in the ending â€Å"belongs to an England where it was still possible to get lost. It belongs to the last moment of the greenwood.†5 The juxtaposition is further highlighted by the fact that whilst Maurice is set in Georgian England, the lovers apparently disappear to an England of the past, however the irony here is that they escape to an escape that was not possible in 19136. Forster justified this on the basis that a happy ending was imperative, â€Å"I was determined that in fiction anyway two men should fall in love and remain in it for the ever and ever that fiction allows, because in this sense Maurice and Alec still roam the greenwood.7† However, searching for a world of the past and waiting for â€Å"a happier year† was not realistically possible and therefore â€Å"Maurice and Alec inhabit a novel twisted in the grip of time8†. As such, it has been argued that these contradictions are Maurice’s flaws, leading some commentators to assert that â€Å"they result from self-hatred and indecision, from escapism and self-indulgence and have therefore disappointed readers of all kinds9†. Conversely, this literal interpretation of Forster’s â€Å"flawed† narrative can

Corporate law Essay Example | Topics and Well Written Essays - 1250 words

Corporate law - Essay Example Sarah, who bought a hotel from Nigel, later realized that the physical condition of the building, housing the hotel, was not in perfect condition as she had been led to believe, by her architect friend, is putting Nigel the proprietor of Colchester Suppliers through litigation. The financial performance of the hotel was also not, in accordance with what the hotel’s accountant had projected to her. Upon the revelation of these discrepancies, Sarah suffered a nervous breakdown, which she squarely blames on Nigel and is suing for responsibility. Sarah’s case against Nigel is a typical case of obligatory law, which integrates personal duty into the law governing such transactions between individuals and corporations. Nigel is not responsible for any wrongdoing, on his part because on the part of the financial performance of the hotel, the accountant made it clear to Sarah that the information presented was without responsibility, on his part, as the accountant. The fact tha t the accountant provided this information, when giving Sarah financial information pertaining to the hotel, shows that Sarah had an obligation to seek an alternative and independent opinion about the hotel’s accounts. This would have helped her make a better judgement of the hotel’s financial position and decide if it was worth her attention. She should not lay blame on Nigel, as the owner of the hotel, because it should have been that the account’s opinion would be bias, in favour of the hotel he or she has been catering for. The accountant’s actions could be partly due to the desire to portray the hotel in a positive light for retaining their position as employees in the event of a transfer of ownership. This transfers part of the blame to the accountant who should be held liable for their actions because the law under the obligations rule subjects them to the duty of telling the truth on facts and knowledge they are privy to (Golding & Edmundson, 2008 p148). Under corporate law, obligation to conform to social rules like telling the truth requires that a sanction be carried out against the accountant because of his/her actions. Obligations of this nature, under the law, make it a duty for someone to conform to some social rules that govern practices in businesses. These obligations are subject to a sovereign authority to obey where the command requires the conveyance of a will and awareness of the attached risk involved in suffering a sanction for non-compliance (Dimond, 2009 p180). Nigel, on his part, did not refuse to divulge information concerning the financial position of the hotel or opinion because Sarah never asked for it. If he had given his opinion, it can be held that he lied about the financial state of the hotel so He should be exonerated of any blame in matters relating to the finances of the hotel. However, at the same, it makes it his duty to ensure that his employee observed the appropriate moral conduct of confo rming to social rules because the accountant was in his employ. His failure to make it his duty and obligation casts some responsibility to him for his accountant’s actions. The obligation law casts more negligence on the buyer and the accountant because they did not do what was meant to be their duty under the law (Davies, 2011 p 318). Sarah consulted her architect friend, Liz, to assess the building the hotel was housed in, and this shows that she

Adoption of Biometric System to Control ATM fraud Essay

Adoption of Biometric System to Control ATM fraud - Essay Example Looking forward to hearing from you and partner with you in providing business solutions that give value to your customers. Yours faithfully, Head of Business Security Systems Practical proposal about ATM fraud Introduction Fraud attempts targeting Automated Teller Machines (ATMs) cards are on the rise. Skimming is one of the techniques used by criminals in this case where they scan or copy personal information from the magnetic strip of a credit card or ATM card. With this information, all the fraudsters need is fake ATMs and use the Personal Identification Number (PIN) to access one’s bank account and defraud customers. This has gone to the extent of bank-owned ATMs with the recent percentage of this criminal activity going as high as 24% in Europe (Abagnale 89). The act is often perpetrated by techno-savvy individuals, where they use a microchip fixed at an ATM or cardholders which copies information from the magnetic strip for all the cards that are being used on a given m achine. The information is then copied and printed on fake cards. This has led countries like Canada to adopt more protection for their ATM cards. A typical example is the use of chip-and-PIN debit cards which have more protection in the form of an extra layer of chip material. Cards developed through this technology are hard to replicate thus reduced losses as a result of card skimming (Bianchini et al., 233). Business transactions world over are increasingly being settled using cards as opposed to cash-based settlements and therefore, without embracing innovative technologies that aim to prevent fraud than detection, card issuers and users will remain vulnerable. As use of cards increases, so are ATM Fraudsters. Most card issuers mainly banks continue to incur huge costs in terms compensations, card replacement, and cost of investing in fraud prevention and detection mechanism. Therefore, there is a need for card issuers to be ahead of the game by innovating and adopting far near fraud-proof technologies (Newman, 3-4). Proposed Solution Since the chip-and-PIN is not foolproof, we need to employ the use of more sophisticated technologies. One such technology that has stood the test of time is the biometric technology, which involves automated identification and data capture (AIDC). The system has automated methods of verifying the identity of persons using physiological attributes as opposed to the chip and PIN, which involves manual keying in of information on a keyboard. Normally, the technology works by capturing the physiological or behavioral characteristics for the first time which is then stored in a central database. Information recorded may include facial properties or fingerprints. Every time a customer accesses a point of services, installed devices captures, verifies and identifies the person and then gives them access. Since it is almost impossible to impersonate one’s physiological attributes, this technology is more recommended to card i ssuers. The technology has been tested in both private and public institutions with remarkable success. In fact, most organizations are now moving towards adoption of this technology.

The Challenge Of Population Growth In Africa Economics Essay

The Challenge Of Population Growth In Africa Economics Essay It is generally agreed that the challenge of population growth is one of the most serious obstacles to development faced by LDCs in the 21st century. In the long process of human history, the relationship between the production of material goods and human reproduction is always interdependent. Therefore, a certain economy is the foundation of the existence and development of human beings; meanwhile, the reproduction of human beings is the condition for the development of economy. The historical experience has proved that the population growth has to keep relative balance with the development level of economy; otherwise, the human society will be punished by nature certainly. It is undeniable that the fertility of Africa is always out of control since the independence of African countries. In 1970s and 1980s, the average fertility rate of Africa reached 6.8 and 6.7; however, it was still high was around 5.4 in 2004 [1]. Besides the high fertility rate, the size of African population has never stopped increasing. In 1960, the African population was 282 million, which was 9.3 ¼Ã¢â‚¬ ¦ of the world population; however, in 2005, the African population had reached 906 million, which was 14.0 ¼Ã¢â‚¬ ¦ of the whole population in the world [2], in the 45 years, the African population increased trebly. Since Africa has the highest population growth rate and the second largest population in the world, the population burden will put more pressure on the development of economy though Africa is always suffering from poverty. To get through difficult situations, the African countries have to recognize the negative effects of rapid population growth on the developme nt of economy. First, the poor capital accumulation is the bottleneck of development in Africa. The development of economy requires solid foundation, and the material capital is the motive force of the development. The classical economist, Adam Smith emphasized that the accumulation of capital was the precondition of specialization [3]. For African least developed countries, they have abundant resource and labor, and the capital input can determine the level of economic development. Either of low capital output ratio and poor capital accumulation will hinder the development. According to the demographers estimation, an 1 ¼Ã¢â‚¬ ¦ increase on the population will lead the country to pay 3 ¼Ã¢â‚¬ ¦ to 4 ¼Ã¢â‚¬ ¦ of gross national income on the investment of additional population [4]. If more national income invests on the population growth, which means the investment on production will be limited strongly. As the rapid increase on the population in Africa, the structure of population is very you thful and the youth dependency ratio is always highest in the world [5]. Every year, African governments have to take a certain share of new output value to invest on the latest additional population, but Africa is also the region comprising many poorest countries. In 2000, the World Bank made public a name list of fifty nine poorest counties in the world, and thirty eight of them were in Africa [6]. Therefore, substantial fund have been ate by the large population, which leads to low saving ratio and large financial gap. The second negative effect of the large population on LDCs refers to the low quality of the population. In fact, the quality of population can determine the quality of labor directly, and human capital is always regarded as the key of the economic development. Theodore Schultz, the winner of the Nobel Memorial Prize in Economic Sciences, believed that a health and highly educated population was playing an important role in a countrys development [7]. However, the high rise of African population really hinders the improvement of human capital. On one hand, the investment from governments on education has fall much behind the rapid population growth in Africa, which leads to extremely heavy pressure on the education, such as the shortage of educational expenditures and teachers, low school enrollment ratio, high illiteracy rate. In 2001, the UNESCO reported that Africa was the poorest continent in education where the literacy rate was less than 60 ¼Ã¢â‚¬ ¦ [8]. On the other hand, sin ce the mid of 1970s, the African population growth rate was always going beyond the agricultural productivity rate, the self-sufficiency rate of grain and the per capita food expenditure kept decreasing. According to the Malthusian Population Trap, the universal tendency for the population of a country will grow at a geometric rate, however, the food supplies can expand only at a arithmetic tae [9]. Therefore, the food supplies can never satisfy the demand by rapid population growth in Africa. In fact, the African malnutrition population increased from 94 million in 1970s to 210 million in 1990s [10], and now the per capita food expenditure for African population reaches only 85 ¼Ã¢â‚¬ ¦ of the standard set by United Nations [11]. Since the African economy really depends on the agriculture and the export of primary products, the physical labor is still needed in the most regions. So, we have to doubt such large unhealthy and uneducated population could make contributions to the ec onomic development in 21st century. Third, the LDCs have to face the high unemployment rate which is brought by rapid population growth. Todaro points that an excess of job seekers over job opportunities in the LDC economy is the one of the major negative consequences of population growth [12]. In fact, it is normal that every country has a certain amount of people are in unemployment, but once the proportion of unemployment is excess, the economic development will be hindered and the whole society will become instable. Since the independence of Africa, every year the population within working age is becoming larger, and the labor force growth rate has excessed the economy growth rate, the economic sectors cannot create enough job opportunities to fulfill needs. In 1990s, there were average 10 million African people seeking job per year, however, the economic sectors could only absorb half of the additional labor force [13]. Even though the largest economy in Africa, the unemployment rate of South Africa was 41.8 ¼Ã¢ € ¦ in 2002 [14]. We can imagine how terribly high the unemployment rate of other more backward African countries is. Therefore, substantial labor force cannot be made full use of in Africa which really hinders the enlargement of production scale and optimization of industrial structure, in return, the economic backwardness will increase the unemployment rate. Eventually, it is hard for the LDCs to get rid of the vicious circle which combines high employment rate and poor economy. In fact, the population growth is a neutral phenomenon, in the 3/4 time of 20th century, the development of economy was accompanied by the population growth. However, the rapid population growth can slow down the economy growth and hinder the improvement of living standard, especially for LDCs whose foundation of economy is quite weak. If LDCs really want to achieve the Millennium Development Goals in 2015, they should recognize the importance of education and health to control the rapid population growth immediately.

Brain Based Learner Centered Model Education Essay

Traditional direction focuses on rote memorisation and callback with a bringing system which is teacher-directed. Traditional appraisal has focussed on multiple-choice and true or false trials which are designed to mensurate whether the pupils can reply the information contained in the text edition or delivered by the instructor. This traditional theoretical account is being challenged for non maximising the larning possible for all pupils, particularly where higher degrees of thought accomplishments are involved, such as in trouble-shooting Brooks ( Brooks, 1993 ) . Many researches ( Brooks, 1993 ; Caine, 1997 ) have been conducted on maximising studentis acquisition from which new instructional systems design theoretical account have emerged. But no unequivocal replies have originated from them. As Warrington ( 2007 ) summarises, the traditional or ifactory modeli of preparation was developed as a consequence of the industrial revolution, stressing which addressed obeisance, methodicalness, regard for authorization and a standardised course of study. This paradigm of instructional design created a ione-size-fits-alli theoretical account of instruction. In the twenty-first Century, leaders and pedagogues likewise are naming for alterations to run into the demanding demands of a technologically changing, competitory, and more planetary society ( UNESCO, 2000 ) . One country receiving heightened attending is the research in brain-based acquisition and its application to curriculum design and development. The neuroscience, biological science, and pedagogic research are edifying us on how the encephalon plants, and its deduction for the schoolroom ( Abbott, 1997 ) . Research workers in brain-based acquisition ( Caine, Caine, McClintic, and Klimek ( 2005 ) , Erlauer ( 2003 ) , Jensen ( 2005 ) , Slavkin ( 2004 ) , Wagmeister and Shifrin ( 2000 ) , Wolfe ( 2001 ) ) believe that traditional direction may impede the encephalon from larning. In visible radiation of this new information, decision makers, course of study developers, instructors, and other practicians in instruction, have become interested in brain-based acquisition because their work requires an understanding on how the encephalon receives, procedures, and produces information ( Bucko, 1997 ) . It is believed that brain-based acquisition has already had a dramatic impact for the instruction and larning procedure ( Sylwester, 1994 ) . 2.2 How Brain-Based Learning Impacts Education. Specifically based on decisions from research in neuroscience, professors from major universities have incorporated this information into books about larning. In conformity with the suggestions of Marian Diamond, U. C. , Berkeley ; Howard Gardner, Harvard University ; Renate and Geoffrey Caine ; Thomas Armstrong ; Candace Pert, Eric Jensen, schoolroom patterns can be modified by using new theories of instruction and larning based on recent findings. Advocates of brain-based larning insist that there is a difference between â€Å" brain-compatible † instruction, and â€Å" brain-incompatible † patterns and methods which can really forestall acquisition. Hart in Human Brain and Human Learning ( 1983 ) claims that learning without an consciousness of how the encephalon learns is like planing a baseball mitt with no sense of what a manus looks likeiits form, how it moves. Hart says that if schoolrooms are to be topographic points of acquisition, so â€Å" the organ of acquisition, † the encephalon, must be understood and accommodated. Although all acquisition can be, in the broadest sense, considered brain-based, Caine and Caine ( 1991: 31-32 ) specify brain-based acquisition as larning which acknowledges the brainis regulations for meaningful acquisition, and organizes learning with these regulations in head. Caine and Caine describe the nucleus rules directing brain-based instruction: * The encephalon is a parallel processor. It can execute several activities at one time. * The encephalon perceives wholes and parts at the same time. * Information is stored in multiple countries of the encephalon, and can be retrieved through multiple memory and nervous pathways.i * Learning engages the whole organic structure. All acquisition is mind-body: motion, nutrients, attending rhythms, and chemicals modulate learning.i * The human pursuit for significance is unconditioned. * The hunt for significance comes through patterning. * Emotions are critical to modeling and drive our attending, significance and memory. * Meaning is more of import than merely information. * Learning involves focused attending and peripheral perceptual experience. * We have two types of memory: spacial and rote. * We understand best when facts are embedded in natural spacial memory. * The encephalon is societal. It develops better in concert with other encephalons. * Complex acquisition is enhanced by challenge and inhibited by emphasis. * Every encephalon in uniquely organized. * Learning is developmental.i The deduction of these rules for preparation analysts and trainers has a direct impact on determinations associating to curricula, instructional methodological analysis, instructional stuff, and appraisal. 2.3 How Brain-Based Learning Helps Shape Knowledge Acquisition. The brainis acquisition capacity is eternal. Caine and Cain ( 1991, 1997 ) study that each healthy encephalon is equipped with a set of unbelievable characteristics: * An tremendous capacity for memory * The ability to self-correct and learn from experience * An unlimited capacity to make Theory on encephalon research has led to a comprehensive, instructional attack to maximise pupil acquisition, and to run into studentis single acquisition demands. The research on encephalon hemisphericity acknowledges the fact that there are differences in larning manners and that our definition of intelligence may be excessively limited. Keefe ( 1987: 16 ) defines larning manners as, icharacteristic cognitive, affectional, and physiological that serve as comparatively stable indexs of how scholars perceive, interact with, and respond to the acquisition environmenti . We could reason that this addresses the ihowi of larning. How do we treat and see cognition? How do we form and retain information? Do we near larning consecutive or randomly? The affectional constituents of larning include personality traits related to countries of duty, motive, continuity, and peer interaction ( Dunn and Dunn, 1978 ) . In other words, do we prefer to work entirely or in groups? Are we concerted or competitory? Traditional direction has ever emphasized abstract receiving and brooding processing, where learner-centered direction allows for all receiving and processing manners. In larning centered direction, course of study emphasizes the accomplishments of intuition, feeling, feeling, imaginativeness and syntheses, every bit good as the traditional manners of analysis, ground, and consecutive job work outing. Direction should be designed to link with all larning manners by utilizing jumping combinations of experience, contemplation, conceptualisation, and experimentation ( UCF Faculty Centre for Teaching and Learning ) . The assorted theories on larning available from Jung, Myers-Briggs, Mok, Keirsey and Bates, Hanson, Silver and Strong manners portion the belief that people learn otherwise. Learning depends on the capacities, intelligence, gender, sex, civilization, personality traits, and motive amongst others of persons. One widely used theoretical account used is Bernice McCarthyis 4MAT System. McCarthy ( 1997: 46 ) provinces that, iThe 4MAT system knows the typical manner that each scholar brings to the schoolroom, while assisting each pupil grow by get the hanging the full rhythm of larning stylesi . 4MAT ( McCarthy, 1981 ) is a constructivist theoretical account of teaching method which believes that effectual direction must travel through four indispensable stages of acquisition: scholar motive, conceptual command, application of thoughts, and originative synthesis. The 4MAT system is a theoretical account for instructional design, based on the research of larning manners and encephalon hemisphericity. The 4MAT System is based on left and right encephalon hemisphere, and emphasizes staff development. Dr. McCarthy tells us, that if all instructors taught in each of the four acquisition manners 25 % of the clip, all pupils in any category on any topic would be reached ( The Dunn & A ; Dunn larning manner theoretical account, 2001 ) . Alternatively of concentrating on the pupil ‘s learning manner, she focused on staff development developing all instructors to include all four acquisition manners in showing each larning undertaking. The work of John Dewy, Anthony Gregorc, Karl Jung, David Kolb, David Merrill, and Helizabeth Wetzig influenced McCarthy ( 1980 ) . David Kolbis experiential acquisition theory is the footing of the 4MAT system. Kolb`s research highlighted how experiential acquisition relates to cognitive development. This theory espouses the belief that acquisition is a uninterrupted procedure by which persons refine and incorporate a distinguishable set of independent systems that give significance to lifeis experiences ( McCarthy, 1997 ) . Kolbis theoretical account identifies a procedure through which four manners of human experience are engaged at different degrees to make a complete degree of understanding. The interaction between and among the manners of concrete experience ( CE ) , brooding observation ( RO ) , abstract conceptualisation ( AC ) , and active experimentation ( AE ) is required for acquisition ( McCarthy, 1980 ) . Honey and Mumford ( Sadler-Smith, 1996: 29-37 ) translated Kolbis work into a categorization system of larning manners based on the interaction between the manners: militants, reflectors, theoreticians, and pragmatists. * Militants like practical work such as labs, field work, observation exercisings and utilizing ocular beginning stuff for information. * Reflectors like to larn by watching others, by taking clip to see observations of their ain experience. * Theorists like talks, reading documents on subjects, sing analogies. * Pragmatists like simulations, instance surveies, prep. Therefore the four types might near larning in different ways. For illustration, pupils must larn to weld a pipe utilizing an electric-arc welding machine. Militants might merely get down utilizing it and experience their manner into it. Reflectors might hold a spell at utilizing it and so take clip to believe about what they have merely done. Theorists might get down by reading the manual. Pragmatists might get down the undertaking, but do frequent mentions to the pupil manual. The four types of acquisition in Kolbis theory can be seen as cyclical phases through which a scholar can come on ticker, think, feel, and do, every bit good as categorizing specific sorts of larning experience. The 4MAT system ( McCarthy, 1987 ) expanded on Kolbis theory by uniting research on encephalon hemisphericity. Harmonizing to Bernice McCarthy, developer of the 4MAT system, there are four major larning manners, each of which ask different inquiries and expose different strengths during the learning procedure. Harmonizing to McCarthy, i4MAT benefits instructors by giving them a model to plan larning activitiesi ( McCarthy, 1990 ) . This is besides the instance for instructional interior decorators who design plans of instructions, every bit good as schoolroom and workshop exercisings. Figure 1 shows the 4MAT system. Figure 2.1i The 4MAT System In the 4Mat System ( McCarthy, 1990 ) , pedagogues consecutive design lessons concentrating on four issues: * Personal Connections: How can I assist pupils do connexions between the content and their immediate lives? * Concept Development: How can pupils incorporate this information and see how it fits within the overall class? * Practical Applications: What can pupils make in the acquisition environment utilizing the information to see it at work? * Creative Integration: How can pupils use this information in original and more complex ways? The research on larning manners support that persons learn in different ways, differences in larning manner are related to forces motive and public presentation, acquisition is a uninterrupted procedure of distinguishing and incorporating experiences, and scholars expand and refine differing manners by sing them ( McCarthy, 1997 ) . The reappraisal of literature nowadayss noticeable deductions for instructional design and methodological analysis. The traditional mentality of the ifactory modeli of instruction and preparation, which dominated educational patterns for a century, has been redefined ( Darling-Hammond, 2003, p. nine ) . Teaching which emphasizes on rote memorisation and the acquisition of unrelated, stray facts does non ease the transportation of larning or use the encephalon expeditiously. Leslie Hart ( 1983 p.xiv ) provinces, iAs the effects of long development, the encephalon has manners of operation that are natural, effortless, effectual in using the enormous power of the astonishing instrument. Coerced to run in other ways, it functions as a regulation reluctantly, easy, and with abundant errori . The encephalon continually seeks significance and thrives in an environment rich with complex and meaningful challenges. For instructional stuff to be effectual, the information should be presented in a manner for the encephalon to pull out pattern, instead than enforce it ( Caine and Caine, 1991 ) . Instructional interior decorators must redefine the manner they write developing stuff by developing meaningful, connecting, and associating cognition. They need to develop a rich choice of methods and attacks which continually augment the learning experience. Several attacks compatible with brain-based acquisition are presently used to learn. Thematic units of direction, concerted acquisition, incorporating the course of study through interdisciplinary instruction, and whole linguistic communication direction are a few of these learning methods. Course of study interior decorators need to compose instructional stuff that engages studentis involvement through relevant life experiences in an ambiance of wonder and self-discovery. The course of study must be built around the alone endowments, strength, failing, and larning manners of the pupil in the schoolroom. Activities which are meaningful to pupils must be organized ( McCarthy, 1997 ) . The end of brain-based acquisition is to supply maximal benefit to all pupils without utilizing a ione-size-fits-alli expression. The more we approach meaningful, ambitious, and relevant acquisition in the schoolroom, the more antiphonal acquisition will be to our learner population which must be prepared to run into the challenges of the twenty-first Century. 2.4 3. What are the issues related to the execution of a learner-centered theoretical account? Rather than being seen as exclusions to the regulation that schools can non alter, the development of a little figure of advanced patterns and schools may alternatively reflect the regulation that schools can merely alter through the monumental attempt, unusual resourcefulness, and strong leading of cardinal persons or groups ( Hatch, 2000: 581 ) . Several factors that can curtail course of study invention have been identified in the literature. These relate to both the agent of alteration ( instructional interior decorators ) and the context in which the invention is taking topographic point. They include issues of clip, outlooks, inaccessibility of needed instructional stuffs, deficiency of lucidity about the reform, instructional designersi deficiency of accomplishments and cognition, and the initial mismatch between the iresidual ideologiesi and the rules underlying the course of study invention. Other obstructions relate to organisational agreements such as function overload, stiff programming of clip, describing systems, and failure of disposal to acknowledge and understand its function in alteration ( Nolder, 1990 ; Gross et Al. as quoted in Snyder et al. , 1992 ) . Research into curriculum airing and execution, and factors finding their success, found a focal point with the work of Fullan and Pomfret ( 1977 ) , who studied 16 instance surveies of attempted invention in American schools and found that all of them had resulted in some grade of failure. For about two decennaries, research workers examined the phenomenon of educational alteration, discussed its features and determiners, listed the accomplishments of the ‘change agent ‘ and suggested ways in which the procedure might be improved ( Fullan, 1993 ) . All of this research has a common subject, and that is that course of study alteration is a complex and hard procedure and requires careful planning, equal clip, support, support and chances for teacher engagement. Much of the literature recognizes the trouble of finding a individual theoretical account to accommodate all. Smooth and successful course of study alteration is tremendously hard and clip consuming and can non be accomplished without possible implementers going personally involved and accepting the alteration on their ain footings and harmonizing to their ain concepts of world. United Kingdom research workers ( Kelly, 1982 ; MacDonald & A ; Rudduck, 1971 ; MacDonald & A ; Walker 1976 ; Rudduck, 1991 ; Stenhouse, 1975 ) long have stressed the importance of a strong engagement function in course of study alteration and the demand for engagement of cardinal forces in the development and determination devising procedure. However, ownership is delicate, really hard to specify or step, and has many degrees. The human face of collaborative squads working creatively on specifying and make fulling their ain demands can be freakish and tense with struggle and emotion. On the other manus, collaborative development frequently needs to be steered and coached, and sometimes top-down determinations need to be made on theoretical issues which are outside developing analysts ‘ cognition and experience. Besides, developing analysts might necessitate to be coached to collaborate in alteration. 2.5 What is Action-learning? Action-learning ( AL ) is defined as a method that enables little groups to work on a regular basis and jointly on complicated jobs, take action, and learns as persons and as a squad while making so ( McGill and Beaty, 2002: 12 ) . The most common applications of Action-learning are in professional and managerial acquisition and development ( Revans, 1998 ) . Revan states that AL is widely used to pull off a work-based undertaking or plan in which set members are involved and for which they have a degree of duty and are hence able to realistically act upon their actions. It is besides used to happen and implement solutions to an issue that concerns how fit members operate in their work context, and one that they wish to better and that could profit from the support and challenge of the other members. Action-learning normally involves: * Participants tackle existent jobs ( no irighti reply ) in existent clip * Participants meet in little stable larning groups ( called iSetsi ) * Each Set holds intermittent meetings over a fixed plan rhythm * Problems are relevant to a participantis ain workplace worlds * A supportive collaborative acquisition procedure is followed in a Set * Process is based on contemplation, oppugning, speculation and defense * Participants take action between Set meetings to decide their job By these agencies, Action-learning seeks to throw a net around slippery experiences, and capture them as acquisition. The single makes sense of an experience by gestating it and generalising the replicable points ; and he plans for future actions based on the acquisition gathered. The set provides the forge in which an individualis actions are shaped through their ain personal contemplation and the oppugning penetration of fellow set members. Harmonizing to Revans, a cardinal point is that actions and results still remain the duty of the single participant. Action-learning provides a pattern field for larning to happen, whilst acknowledging that existent duty prevarications outside any schoolroom environment: it lies with the participants who must have the concern results. Further, in utilizing the organisation itself as a acquisition research lab, it does non necessitate any particular set of conditions to be in topographic point before it can be effectual. Action-learning plants good in a bureaucratism, in a level organisation, in houses culturally hostile to instruction and development, in houses promoting self-actualization ( Smith & A ; Peters, 1997 ) . It does so because its whole ethos is larning about the environing context, and larning to be effectual within it, therefore leveraging the prevalent civilization to its ain advantage. As a consequence, the development demands of the organizationis directors, executives and high-potentials are satisfied through activities which focus on the important current and future demands of the organisation. This leads to the justifiable charge of Action-learning as a narrow ( but deep ) larning docket, instead than a wide but superficial one. This development is addressed as a concern service proviso ; geared to supply exactly what is required, when it is required, where it is required, in the signifier in which it is required. 2.6 What is the Action-Learning Framework? The Center for Applied Research ( 2005 ) describes the action-learning model has holding four stages. Learning occurs in each one. 1. Frame i Define the particular job the group is seeking to turn to, research the premises made in specifying the job. Tie formal acquisition to job definition. 2. Charge i Set explicit ends ( deadlines and public presentation outlooks ) for the undertaking squad to carry through, and depict the procedure and staffing required. 3. Act i Execute undertaking work, following an agreed upon workplan. Connect to executive patrons and other cardinal stakeholders for counsel and blessing. 4. Reflect & A ; Review i Step back from action and reflect on experience, associating squad work to personal development. Consolidate lessons learned and integrate them into the undertaking as it unfolds. At the terminal of the undertaking, distribute lessons learned to the larger organisation in a meaningful manner. The procedure is iterative. The lessons learned by the undertaking squad should increase apprehension of the issues and lead to a re-framing of the job. Figure 2.2i the uninterrupted Action-learning procedure Having established what Action-learning is, who should be involved, and how it could help passage, it is of import to set up what the barriers to a successful Action-learning procedure could be. Clearly Action-learning could be a powerful tool but there will be things that will acquire in the manner of it being successfully implemented into any administration ( Marquardt, 1996: 406 ) . Some of these barriers are existent and some are simply perceived. Some are internal and some are external. 2.7 Barriers to Organizational Change Changing the manner we do ibusinessi creates pandemonium. But within pandemonium is an array of chances. Bush ( 2006 p.45 ) suggests that alteration can be inhibited by bing constructions within an administration ; this can be explained farther by O'Neill ( 2006 ) who implies that lasting squads who may hold settled work and societal forms are likely to be extremely immune to alter. This concurs with the instructions of Barbour ( 2005 p.45 ) who found that imembers are genuinely mutualist on each other and are close sociallyi . O'Neill went farther to propose that collaborative direction theoretical accounts such as Action-learning may merely see the indispensable early success where persons can elect to work on the footing of bing friendly relationship groups or where they feel that they personally will derive more by join forcesing than by moving in isolation ( 2006 p.85 ) . Goals and Aims Undefined ends and aims can be a barrier to Action-learning. Fabian and Simpson ( 2002 ) suggest that staffs are likely to hold uncertainnesss and insecurities at times of alteration. Therefore, clear ends and aims must be an built-in portion of the Action-learning procedure. Organizational Culture Organizational civilization is ithe form of shared basic premises – invented, discovered, or developed by a given group as it learns to get by with its jobs of external version and internal integrating – that has worked good plenty to be considered valid and therefore to be taught to new members as the right manner to comprehend, believe, and experience in relation to those problemsi ( Schein 1985 ) . Leadership Commitment Leadership committedness is identified in the literature as an of import and major factor to successfully implement Action-learning. In successful execution in any organisation, leading and civilization play a major function. Some of the features of leaders have been identified as their being airy and transformational ; they promote and O.K. of squad work, larning, engagement, and coaction. The leading manner of directors can drive an organisation to success by assisting them attain their ends and aims ( Rad, 2006 ) . Low tolerance of alteration Resistance is an inevitable response to any major alteration. Persons of course rush to support the position quo if they feel their security or positions are threatened. Folger & A ; Skarlicki ( 1999 ) claim that â€Å" organisational alteration can bring forth incredulity and opposition in employees, doing it sometimes hard or impossible to implement organisational betterments † . Undoubtedly, opposition to alter is a cardinal subject in alteration direction and should be earnestly considered to assist the organisation to accomplish transmutation. In drumhead, apprentice trainees need an instructional theoretical account that will dispute the acquisition potency and better fix them to fall in the work force. The traditional theoretical account does non fix trainees adequately, particularly where higher degrees of thought accomplishments are involved. Traditional instruction and acquisition theoretical accounts, which convey a formal, abstract procedure, are frequently far removed from the specificities of existent universe pattern. The current theoretical account was established in the early 1970 and was non revised since so. The traditional theoretical account is no longer allow to supply trainees with the accomplishments, cognition and attitude required to run into a fast changing and quickly turning company. From this state of affairs emerged a demand to revise the current instruction theoretical account with one that can concentrate in developing future employees that are capable of thought and work outing jobs. Curriculum alteration is a complex and hard procedure and requires careful planning, equal clip, support, support and chances for interior decorators and trainers engagement. To accomplish this ambitious end, action-learning appears to be the itooli of pick. Action-learning provides a tested and true method to help persons and administrations to accommodate to a quickly changing universe and to manage hard state of affairss altering a course of study more efficaciously. This attack is considered to be one of the most of import constructs to hold emerged in direction and organisational development. 3. Methodology This action-research is based on the undermentioned research inquiries: 1. What are the issues with JSC & A ; TUis current instructional development theoretical account with respects to Saudi Aramcois apprentices plan for new employees? 2. How might a learner-centered instructional development theoretical account aid decide the issues from our current instructional theoretical account? 3. What are the issues related to the execution of a learner-centered theoretical account? 4. How might Action Learning support a sustainable alteration in Company X course of study design unitis instructional design theoretical account? This survey adopted action-research as a methodological analysis to making alteration in Company X preparation and development. In this survey, action-research and action-learning are synonymous. The chief difference lies in that action-research is the coverage of the findings where action-learning is the procedure used for the action-learning undertaking. This attack is supported by Hase in iDeveloping Learner Capability through Action-Research: From Pedagogy to Heutagogy in the Workplacei ( 2006 ) . Using action-learning created a paradigm displacement in Company X occupation accomplishments unit. Employees who became members of the AL squad were no longer isolated in their pattern. In other words, the AL squad became a community of pattern where members connected through shared jobs, explored new possibilities to work out them, learned from each other and acted to present consequences to the organisation. 3.1 What is research? First it must be established precisely what educational research is. Research is the orderly probe of a capable affair for the intent of adding to knowledge. Research can meanire- searchi implying that the capable affair is already known but, for one ground or another, needs to be studied once more. Alternatively, the look can be used without a dash and in this instance it typically means look intoing a new job or phenomenon ( Borg and Gall, 1989 ) . Within the kingdom of educational planning, many things are ever altering: the construction of the instruction system, course of study and text edition s, manners of instruction, methods of instructor preparation, the sum and type of commissariats to schools such as scientific discipline research labs, text editions, furniture, schoolroom supplies, and so on. These alterations may take to an betterment, or a deterioration, in the quality of an educational system. In comparing, Pearson ( 1995:15 ) Tells us that researchiis the systematic procedure of roll uping and analysing information to increase our apprehension of the phenomenon under survey. It is the map of the research worker to lend to the apprehension of the phenomenon and to pass on that understanding to others. There are many types of research methods available to a research worker. Research methods are used to find, discover, interpret, and invent facts. The word research and its derivative agencies, â€Å" to look into exhaustively † .iResearch methodsiare used to come up with â€Å" new cognition † . Through probe and find procedures, research methods help to progress many different scientific Fieldss. In drumhead, research is a powerful activity and is conducted for specific ground: to reply a peculiar inquiry or to work out a specific issue ( Depoy and Guitlin, 1998 ) . 3.2 Qualitative or Quantitative Data? This research used quantitative and qualitative informations aggregation and analysis. Kerlinger argues that â€Å" There ‘s no such thing as qualitative informations. Everything is either 1 or 0 † ( Miles and Huberman, 1994: 40 ) . D. T. Campbell asserts that â€Å" all research finally has a qualitative foundation † ( Miles and Huberman, 1994: 40 ) . Many other research workers agree that these two research methods need each other more frequently than non. However, because typically qualitative informations involves words and quantitative informations involves Numberss, there are some research workers who feel that one is better ( or more scientific ) than the other. Another major difference between the two is that qualitative research is inductive and quantitative research is deductive. In qualitative research, a hypothesis is non needed to get down research. However, all quantitative research requires a hypothesis before research can get down. Specifying the function of the research worker is another cardinal difference between the two. In quantitative research, the research worker is ideally an nonsubjective perceiver that neither participates in nor influences what is being studied. In qualitative research, nevertheless, the research worker learns about a state of affairs by take parting or being immersed in it. These basic implicit in premises of both methodological analysiss guide and sequence the types of informations aggregation methods employed. Although there are clear differences between qualitative and quantitative attacks, some research workers maintain that the pick between utilizing qualitative or quantitative attacks really has less to make with methodological analysiss than it does with positioning oneself within a peculiar subject or research tradition. The pick of which attack to utilize may reflect the involvements of those carry oning or profiting from the research and the intents for which the findings will be applied. Decisions about which sort of research method to utilize may besides be based on the research worker ‘s ain experience and penchant, the population being researched, the proposed audience for findings, clip, money, and other resources available ( Hathaway, 1995 ) . Some research workers believe that qualitative and quantitative methodological analysiss can non be combined because the premises underlying each tradition are so immensely different. Other research workers think they can be used in combination merely by jumping between methods: qualitative research is appropriate to reply certain sorts of inquiries in certain conditions and quantitative is right for others. Others think that both qualitative and quantitative methods can be used at the same time to reply a research inquiry. To a certain extent, research workers on all sides of the argument are right: each attack has its defects. Quantitative research frequently prompts responses or people into classs they might non belong in, in order to do significance. Qualitative research, on the other manus, focuses excessively closely on single consequences and fails to do connexions to larger state of affairss or possible causes of the consequences. Rather than dismissing either attack for its downsides, we should happen the most effectual ways to integrate elements of both to guarantee that their surveies are as accurate and thorough as possible. It is of import for research workers to recognize that qualitative and quantitative methods can be used in concurrence with each other. For the intent of this research, qualitative informations were collected in analogue to quantitative informations and consisted of the followers: * Trainers and trainees questionnaires * Classroom observation, * In-depth interviews with trainers, and * Document Analysis ( particularly rating studies and gap analysis studies ) 3.3 Action-research Action-research is known by many other names, including participatory research, collaborative enquiry, Action-learning, and contextual action-research, but all are fluctuations on a subject. Put merely, action-research is ilearning by doingi – a group of people identify a job, do something to decide it, see how successful their attempts were, and if non satisfied, seek once more. While this is the kernel of the attack, there are other cardinal properties of action-research that differentiate it from common problem-solving activities that we all engage in every twenty-four hours. Gilmore, Krantz and Ramirez ( 1986: 161 ) specify action-research as: â€Å" Action-research†¦ aims to lend both to the practical concerns of people in an immediate debatable state of affairs and to foster the ends of societal scientific discipline at the same time. Therefore, there is a double committedness in action-research to analyze a system and at the same time to join forces with members of the system in altering it in what is together regarded as a desirable way. Carry throughing this twin end requires the active coaction of research worker and client, and therefore it stresses the importance of co-learning as a primary facet of the research procedure. † Several properties separate action-research from other types of research. Primary is its focal point on turning the people involved into research workers, excessively – people learn best, and more volitionally use what they have learned, when they do it themselves. It besides has a societal dimension – the research takes topographic point in real-world state of affairss and purposes to work out existent jobs. Finally, the initiating research worker, unlike in other subjects, makes no effort to stay degage, but openly acknowledges their prejudice to the other participants. Figure 3.1i Action-research System Model This survey intends to utilize the Action-learning methodological analysis. By its nature, Action-learning is a manner of speed uping peopleis acquisition and edifice capableness for managing disputing state of affairss to convey about alteration. If a alteration is desired, and the agencies by which the alteration should take topographic point is unknown, so Action-learning is a good manner to continue. This attack has been used in many organisations from different industry sectors every bit good as in educational environments where it is highly effectual. In response to our dynamic universe of work, current organisation frequently demands uninterrupted employee acquisition and development. In many state of affairss, a cardinal premise is that organisational endurance is dependent on acquisition, maintaining gait with, or progressing beyond the rate of alteration exhibited in the external environment ( Boshyk, 2002 ) . In the instance of Company X course of study unit, alteration in the manner course of study is designed is needed to back up trainers in presenting cognition, accomplishments and attitude utilizing a learner-centered attack. The traditional instruction theoretical account no longer suits the demands of immature Saudis. The company needs a work force whose cognition and accomplishments are built around critical thought instead than memorisation. Action-learning is a problem-solving tool. It is built around a job ( in this instance, a undertaking ) . Giving the chance to those that perform the occupation of planing course of study to place solutions and to implement them can significantly increase success and create sustainable alteration. Research demonstrates that larning without application is uneffective. An action without larning fails to develop your organisation ( Dixon, 2004: 18-23 ) . It marries analysis and action, contemplation and making, organisational development and bottom-line public presentation. By unifying these attempts, you drive to consequences in new ways and build capableness. In iAction Learning i Improving Organizational Performance through Team Learningi , the Center for Applied Research ( 2005 ) listed cardinal rules of successful Action-learning: * Executive Sponsorship is Crucial i In order to hold an effectual acquisition procedure, an executive patron must guarantee that proper resources are given to the undertaking and supervise the procedure and consequences. In this instance, the research was converted to a section enterprise, resources and budget was allocated, and the enterprise was tracked by upper-management. * Connect Action-learning to Real Business Issues i The push of the projectithe job to be solvedimust be relevant to the scheme or current demands of the organisation. Otherwise, the consequences of the undertaking might non be seen as important by the larger organisation, and the undertaking feels like an iexercise.i Since the end of this research was aligned with a existent business-need, recognized by both the business-lines and the preparation section, the result of it was of adequate significance for the company to apportion resources, clip and money to it. * Learning is Continuous i Learning happens throughout the procedure, non merely at the terminal. * The Future is Already Here i The Action-learning squad need non get down from abrasion. The solution to any job likely already exists someplace in the organisation. Action-learning uncovers and amplifies those solutions. * The Potential Solution Should Have Impact i A challenge posed by Action-learning is the perceptual experience that it produces excess work. If the procedure is linked to a long-standing or critical job, nevertheless, the procedure will be thought of as productive instead than merely excess work. * Get the Learning Noticed i Exporting outcomes from the undertaking into the wider organisation is critical. A procedure is needed to capture and administer larning throughout the organisation. To back up this research, a figure of action-learning meetings have been conducted within Company X course of study unit, sister units from the same division every bit good as the Training & A ; Development section. A absorbing result of this is that, although these meetings were meant to back up this specific action-learning research, a figure of turning enterprises to undertake similar issues are now being researched and implemented at all degrees. This procedure is improbable to be without its jobs. Chiefly, most people are unfamiliar with the basic processs and capablenesss of Action-learning. Second, Saudi Aramco directors are non used to nor inclined to swear and depute their control. Finally, directors may non be willing to supply the clip that Action-learning groups require to work out this job. An of import measure in Action-learning is to clearly specify the root jobs to work out. Action-learning advocators oppugning and contemplation to motivate a deeper degree of analysis, to prove premises, and to research possibilities. Within a group, work-based jobs are discussed and reframed in a acquisition context. Therefore, the research worker has gathered some cardinal determination from Company X recognizing organic structure the Accrediting Council for Continuing Education and Training ( ACCET ) which conducted a comprehensive rating of the course of study design, bringing, and direction of Company Xis apprenticeship plan for new employees ( APNE ) . The aim of the rating, as specified by Company X decision makers, was to find to what degree the APNE plan is run intoing its ends and to urge alterations or betterments that might be warranted. The information from this audit were gathered in October and November 2008 by the attesting organic structure during sites visits. In 20 11, another rating, which was aimed at a specific stage within the APNE plan, was conducted by the Centre of Applied Linguistic ( CAL ) , a non-profit administration. Both administrations, ACCET and CAL came up with really similar findings. Since these visits, the state of affairs has non improved. The undermentioned findings were highlighted in the ACCET study and were used to specify the issues with our plan of direction and to organize the footing for traveling the course of study from teacher-centered to learner-centered. Table 3.1i Certifying Bodyis Findings ACCET Standard h the mission and ends. The establishment maintains all needed certification. The action-learning squad for this undertaking was 14 members of staff chosen at random from the course of study unit. One participant was selected from the five group leaders, one from the two available senior interior decorators, seven from the 24 available interior decorators from the course of study author group, one from the learning staff, one from the in writing group, and one from the papers design staff. Table 3.2 explains the sample for the qualitative research and will be used to guarantee the namelessness of respondents in this study. Table 3.2iSample Group Code of Interviewee The acquisition penchants study was administered to five groups of 12 pupils from each occupation of the APNE plan, chosen randomly: Metallic elements Mechanicss, Welding, Operators, Process Control Technicians, and Maintenance Technicians. The instruction penchants study was administered to one of the two instructors responsible of learning the predating trades. A semi-structured interview was used with each supervisor responsible of each of the five occupation ladders to compare with the positions collected via studies and observations from the schoolroom. This enabled the research worker to reflect similarities or differences between what was compiled from the studies, observations and interviews of the trainees and the trainers. In this research, affecting a smaller sum of topics reduces investing in clip and money. It is believed that samplingican really be more accurate than analyzing an full population, which in this instance is over 2600 trainees, and 650 trainers in five different locations throughout the state, because it affords the research worker a batch more control over the topics. Finally, holding a smaller information set will let the research worker to avoid human mistake when inputting and analysing the information set. On the other manus, there is room for possible prejudice in the choice of suited topics for the research. This may be because the research worker selects topics that are more likely to give the coveted consequences, or that the topics tend to choose themselves. 3.5 The Data Collection Tools Many ways to garner informations are required to set about the research and as Denscombe ( 2007:3 ) explained, there is no 1 right way to take. Different schemes should be used depending on the issue to be undertaken. Triangulation requires the aggregation of informations from a assortment of beginnings, in a assortment of ways, with a assortment of positions. In this survey, interviews, audit studies, questionnaires, and observations were used to roll up informations in a assortment of ways. 3.5.1 The Interview The interview as a information aggregation tool was considered as it provides an chance to roll up better or more informations at less cost ( Ribbins, 2007 ) . The research worker has decided to utilize semi-structured interviews as the method for roll uping my qualitative informations as it fosters a deeper apprehension of the positions of the interviewees. The semi-structured interview can be described as flexible, leting new inquiries to be brought up as a consequence of what the interviewee says. In a semi-structured interview, the interviewer has by and large a model of subjects to be explored ( Lindlof and Taylor, 2002: 195 ) . The interviewing technique is employed in this research because it serves the explorative nature of the survey. It seeks in-depth information about accomplishment formation results. The latter issue and the information to be obtained are really sensitive to interviewees in this survey. Therefore, questioning is the most appropriate attack. This can be achieved through a little sample of representatives from selected sectors instead than concentrating on a big scale population. Interviewing besides enables the interviewer to supplement information obtained from responses, with those gained from observation of gestural reactionsi ( Kumar, 1999:115 ) . Furthermore, this qualitative research falls within the context of detecting possible barriers and challenges for organisational alteration by implementing a new instructional attack. Therefore, it is indispensable to forestall any possibility of misinterpretation of research inquiries that will be asked as the interviewer can either repetition or explicate such inquiries in the topographic point which can merely be accomplished through face-to-face interviewing. The usage of standardised instructions warranted that each supervisor had a similar engagement. Associating the closed inquiries from the trainees and trainers questionnaire meant that the responses of supervisors could be straight compared to the questionnaires without the demand for a deep analysis from the research worker. 3.5.2 The Questionnaire A questionnaire was administered to the trainees and the trainers by the research worker based upon Gary J. Contiis ( 1983 ) work. The Principles of Adult Learning Scale ( PALS ) was developed and validated for mensurating congruency between big instruction practicians ‘ existent discernible schoolroom behaviour and their uttered belief in the collaborative teaching-learning manner. The PALS is self-administered, has 44 points, and can be completed in approximately 10 to 15 proceedingss ( Conti, 1990 ) . There are several grounds behind taking this instrument ; it is easy to administrate, it is easy to construe, it is self-scoring, and non scored by an external agent, it is comparatively speedy to administrate and finish, it has easy reportable graduated tables, and it has dependability and cogency supported by the research. PALS leads to a individual mark and which can be divided as follows: * Teacher centered-extreme: 0-105 * Teacher centered – really strong: 106-125 * Teacher centered – increased: 126-145 * Learner centered-increased: 146-165 * Learner centered – really strong: 166-185 * Learner centered – extreme: 186-205 About everyone has had some experience finishing questionnaires and they by and large do non do people discerning. They are less intrusive than telephone or face-to-face studies. When respondents receive a questionnaire, they are free to finish it on their ain timetable. Unlike other research methods, the respondent is non interrupted by the research instrument. Written studies are non capable to this prejudice because there is no interviewer. On the other manus, the deficiency of an interviewer limits the research worker ‘s ability to examine responses ( Walonick, 1993 ) . Contrasting with in the flesh interviewing, there are no verbal or ocular hints to act upon a respondent to reply in a peculiar manner. Many research workers have reported that interviewer voice inflexions and idiosyncrasies can bias responses ( Barath and Cannell, 1976 ) . Written studies are non capable to this prejudice because there is no interviewer. As suggested by Bell ( 2007 ) the research worker needs to avoid ambiguity, taking and dual inquiries to guarantee the responses are valid and utile in the research. Some might reason that the deficiency of an interviewer limits the research worker ‘s ability to examine responses. Structured questionnaires frequently lose the â€Å" spirit of the response † , because respondents frequently want to measure up their replies ( Walonick, 1993 ) . By leting frequent infinite for remarks, the research worker can partly get the better of this disadvantage. 3.5.3 Observations Observation is a manner of garnering informations by watching behaviour, events, or observing physical features in their natural scene. Marshall and Rossman ( 1995 ) define observation as â€Å" the systematic description of events, behaviours, and artefacts in the societal scene chosen for survey † ( p.79 ) . Observation methods are utile to research workers in a assortment of ways. They provide research workers with ways to look into for gestural look of feelings, determine who interacts with whom, hold on how participants communicate with each other, and look into for how much clip is spent on assorted activities ( Schmuck, 1997 ) . Observations, as used in this research, enabled the research worker to formalize the consequence of both studies. Participant observation in their acquisition environment allowed the research worker acquire the feel for how the stuff is being taught and evaluated. It besides gave the research worker a better cognition of the learning civilization of the trainees against the teaching civilization of the trainers. The research worker conducted a focussed observation utilizing the same PALS questionnaire administered to the trainers and trainees. An excess field was added for observation notes. A focussed observation emphasizes observation supported by interviews and questionnaires, in which the participants ‘ penetrations guide the research worker ‘s determinations about what to detect. As Wolcott ( 2001 ) notes, one should take note of what he is detecting, what is being put into the field notes and in how much item, and what one is nil about the research worker ‘s personal experience in carry oning the research. 3.6 Reliability and Validity The research worker realises the importance of dependability and cogency of the measurement instruments. Schumacher and Macmillan ( 1993:404-406 ) province, iQualitative research workers typically use as many schemes as possible to see the cogency of the design.i The traditional standards for cogency find their roots in a rationalist tradition, and to an extent, positivism has been defined by a systematic theory of cogency. Within the rationalist nomenclature, cogency resided amongst, and was the consequence and apogee of other empirical constructs: cosmopolitan Torahs, grounds, objectiveness, truth, actuality, tax write-off, ground, fact and mathematical informations to call merely a few ( Winter, 2000 ) . Joppe ( 2000 ) gives the undermentioned history of cogency in quantitative research: iValidity determines whether the research truly measures that which it was intended to mensurate or how true the research consequences are.i Researchers normally control cogency by inquiring a series of inquiries and will frequently look for the replies in the research of others. Reliability as defined by Joppe is: iiThe extent to which consequences are consistent over clip and an accurate representation of the entire population under survey is referred to as dependability and if the consequences of a survey can be reproduced under a similar methodological analysis, so the research instrument is considered to be reliablei ( Joppe: 2000: 1 ) . Rooted in this commendation is the thought of repeatability of consequences or observations. Although the research worker may be able to turn out the research instrument repeatability and internal consistence, and, hence dependability, the instrument itself may non be valid. To achieve methodological and answering triangulation in this research, the research worker used several schemes such as observation, interview, papers analysis, and questionnaire. Bush ( 2006 ) stated that look intoing requires triangulation, which means at the data-collection phase seeking farther grounds including speaking to others, analyzing paperss and detecting action. 3.7 Ethical Considerations Because action-research is carried out in real-world fortunes and involves near and unfastened communicating among the people involved, the research worker must pay close attending to ethical considerations in the behavior of his work. Confidentiality must be a given. Richard Winter ( 1996 ) lists a figure of rules which were respected throughout the survey: * iMake certain that the relevant individuals, commissions and governments have been consulted, and that the rules steering the work are accepted in progress by all. * All participants must be allowed to act upon the work, and the wants of those who do non wish to take part must be respected. * The development of the work must stay seeable and unfastened to suggestions from others. * Permission must be obtained before doing observations or analyzing paperss produced for other intents. * Descriptions of othersi work and points of position must be negotiated with those concerned before being published. * The research worker must accept duty for keeping confidentiality. * To this might be added several more points: * Decisions made about the way of the research and the likely results are corporate * Research workers are expressed about the nature of the research procedure from the beginning, including all personal prejudices and involvements * There is equal entree to information generated by the procedure for all participants * The outside research worker and the initial design squad must make a procedure that maximizes the chances for engagement of all participants. The research worker must besides guarantee that the research participants give their consent voluntarily. Additionally, this consent can be withdrawn at any clip ( TCPS2, 2011 ) . This is confirmed by Busher and James who province that ia cardinal rule for building ethical research is that of voluntarism by the participant when prosecuting with research ( Busher and James, 2007: 110 ) . Besides confidentiality will be achieved by keeping namelessness. Hart ( 2003 ) describes namelessness as mentioning to hiding the individuality of the participants in all paperss ensuing from the research. In carry oning interviews, ethical issues are one of the chief concerns. Ethical guidelines published the University of Leicester Code of Practice ( 2012, Online ) were used to steer the research procedure. Following these rules, the action-learning squad was assembled for this research. An enterprise was proposed to the section caput. From this proposal, the action-learning squad met and developed a formal undertaking proposal. The undertaking proposal was submitted to the Accelerated Transformation Program squad and was subsequently approved. The squad met once more and a undertaking program was elaborated in audience with everyone in the action-learning squad. A formal presentation about Action-learning was conducted and the action-learning squad elaborated land regulations to be followed for each action-learning set. The undermentioned action-learning rules and land regulations were charted and adopted: * Merely in a group where it is safe to unwrap ignorance, admit failing and ask for aid is it possible for the job proprietor to larn at sufficient deepness for him to develop as an person * Keep to external and internal clip boundaries to guarantee each individual has a just portion of the clip available. * Statements merely in response to inquiries ; anyone can inquire inquiries. * Merely one at a clip. Merely one individual at a clip is the issue holder, for that clip, the set members are at that place to listen and to enable. If the job proprietor is non acquiring the kind of aid that is needed, he should state so. * Team members have authorization to step in whenever he identifies larning chances. * Team members need to be able to seek out new ways of relating, cognizing that they will acquire constructive feedback and non be blamed for acquiring it incorrect. * Team members need to acquire over any impression of fight or ibetter thani impressions. * Bing a member is voluntary. Any members can elect to go forth the action-learning squad at any minute without accounts. Additionally, supervisors were informed that they could retreat from the interview at any clip and approved verbally at the terminal of the interview to their informations being used. By returning the questionnaire trainees and trainers gave understanding to utilize their informations. Finally, since the research participants have the right to stay anon. , all information solicited was treated with confidentiality and used for the intents of the thesis merely. The paperss provided by the participants were returned or shredded upon petition. Hart ( 2003 ) describes namelessness as mentioning to hiding the individuality of the participants in all paperss ensuing from the research. All participants were guaranteed that the information solicited was treated with maximal confidentiality. 4. Analysis The intent of this survey was twofold. One: to place the acquisition manners of company X trainees enrolled in the industrial proficient colleges and the instruction manners of the teachers. Two: to find if the usage of action-learning can alter the bringing of course of study from a teacher-centered theoretical account to a encephalon based learner-centered theoretical account. This chapter will explicate the analysis conducted to place the current learning-teaching manners, discourse how the information collected helped the action-learning squad place the job, and show how the usage of action-learning can be an efficient tool in altering Company X preparation design and bringing. 4.1 Finding 1 Based on the PALS trainers and trainees questionnaire, the research worker was able to specify the particular job the action-learning squad is seeking to turn to. The Principles of Adult Learning Scale ( PALS ) Conty ( 1983 ) was developed and validated for mensurating congruency between big instruction practicians ‘ existent discernible schoolroom behavior and their uttered belief in the collaborative teaching-learning manner. PALS, trainers and trainees versions, is self-administered, has 44 points, and can be completed in approximately 10 to 15 proceedingss ( Conti, 1990 ) . One-half of the points are worded positively, the others negatively and are arranged indiscriminately. The PALS questionnaires factor tonss are calculated by summing the value of the responses for each item/question in the factor. Then, the research worker compares each traineris factor mark values to their several agencies. Both groups were given a consent signifier. The PALS trainersi questionnaires were distributed to five trainers during spring of 2012. Engagement to the study was non compulsory. Surveies were collected and placed into an envelope which was sealed before the trainers. Data analysis was conducted before the schoolroom observations took topographic point. The PALS is interpreted as follows: If the mark is equal to or greater than each several mean, so this suggests that such factors are declarative of the traineris learning manner. Those tonss that are less than the average indicate possible countries for bettering a more learner-centered attack to learning. An person ‘s entire mark on the instrument is calculated by summing the value of each of the seven factors. Tonss between 0-145 indicate that the manner is iteacher-centered.i Tonss between 146-220 indicate that the manner is ilearner-centered.i The overall PALS mark can be broken down into seven factors as shown in Table 4.1. While the overall mark indicates the trainer ‘s general manner, the factor scores place specific elements that make up this manner. A high mark on each factor represents support of the construct implied in the factor, while a low mark indicates support of the opposite construct Table 4.1i Factor Score Valuess Factoring procedure Of the five trainers ‘ that responded to this study, all five of their tonss were below the average mark of 146 which indicated that they all prefer a instructor centered attack to instruction. 4.1.1 Trainees Questionnaire The 2nd aim of this study was to find the pupils larning penchants against the trainers learning penchants. The trainees from the same group of trainers participated in this survey. The pupils were given the questionnaire during one of the category Sessionss in the spring term of 2012. A treatment of larning manners and expressed instructions on how to finish the study preceded the distribution. Student engagement was voluntary, so merely completed studies were placed in an envelope. After all the studies had been collected, the envelope was sealed and taken by the research worker for analysis of the informations. The consequences were so analysed and compared with the Index of Learning Styles ( ILS ) formulated by Richard M. Felder and Linda K. Silverman as per the tabular array below. The Index of Learning Styles was created in 1991 by Richard M. Felder, a chemical technology professor at North Carolina State University, and Barbara A. Soloman, so the coordinator of reding for the N.C. State First-Year College. The four acquisition manner dimensions of the instrument were adapted from a theoretical account developed in 1987 by Dr. Felder and Dr. Linda K. Silverman, an educational psychologist so at the University of Denver. The first version of the instrument was administe

What is Chromosome 21?

Down syndrome (DS) is a condition in which extra genetic material causes delays in the way a child develops, and often leads to mental retardation. It affects 1 in every 800 babies born. The symptoms of Down syndrome can vary widely from child to child. While some kids with DS need a lot of medical attention, others lead very healthy and independent lives. Though Down syndrome can't be prevented, it can be detected before a child is born. The health problems that can go along with DS can be treated, and there are many resources within communities to help kids and their families who are living with the condition. Normally, at the time of conception a baby inherits genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases of Down syndrome, however, a child gets an extra chromosome – for a total of 47 chromosomes instead of 46. It's this extra genetic material that causes the physical and cognitive delays associated with DS. Although no one knows for sure why DS occurs and there's no way to prevent the chromosomal error that causes it, scientists do know that women age 35 and older have a significantly higher risk of having a child with the condition. At age 30, for example, a woman has less than a 1 in 1,000 chance of conceiving a child with DS. Those odds increase to 1 in 400 by age 35. By 42, it jumps to about 1 in 60. How Does Down Syndrome Affect a Child? Kids with Down syndrome tend to share certain physical features such as a flat facial profile, an upward slant to the eyes, small ears, a single crease across the center of the palms, and an enlarged tongue. A doctor can usually tell if a newborn has the condition through a physical exam. Low muscle tone and loose joints are also characteristic of children with DS, and babies in particular may seem especially â€Å"floppy. Though this can and often does improve over time, most children with DS typically reach developmental milestones – like sitting up, crawling, and walking – later than other kids. At birth, kids with DS are usually of average size, but they tend to grow at a slower rate and remain smaller than their peers. For infants, low muscle tone may con tribute to sucking and feeding problems, as well as constipation and other digestive issues. In toddlers and older children, there may be delays in speech and self-care skills like feeding, dressing, and toilet teaching. Down syndrome affects kids' cognitive abilities in different ways, but most have mild to moderate mental retardation. Kids with DS can and do learn, and are capable of developing skills throughout their lives. They simply reach goals at a different pace – which is why it's important not to compare a child with DS with typically developing siblings or even other children with the condition. Kids with DS have a wide range of abilities, and there's no way to tell at birth what they will be capable of as they grow up. Medical Problems Associated with Down Syndrome. While some kids with DS have no other health problems, others may experience a host of medical issues that require extra care. For example, half of all children born with DS also have congenital heart defects and are prone to developing pulmonary hypertension (high blood pressure in the lungs). A pediatric cardiologist can monitor these types of problems, many of which can be treated with medication or surgery. Approximately half of all kids with DS also have problems with hearing and vision. Hearing loss can be related to fluid buildup in the inner ear or to structural problems of the ear itself. Vision problems commonly include amblyopia (lazy eye), near- or farsightedness, and an increased risk of cataracts. Regular evaluations by an audiologist and an ophthalmologist are necessary to detect and correct any problems before they affect a child's language and learning skills. Other medical conditions that may occur more frequently in children with DS include thyroid problems, intestinal abnormalities, seizure disorders, respiratory problems, obesity, an increased susceptibility to infection, and a higher risk of childhood leukemia. Fortunately, many of these conditions are treatable. What is Chromosome 21? According to wikipedia. org, Chromosome 21 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. The trisomy of the 21 causes Down Syndrome. Chromosome 21 is the smallest human chromosome, spanning almost 47 million nucleotides (the building material of DNA) and representing about 1. 5 percent of the total DNA in cells. The Human Genome Project announced that they had determined the sequence of base pairs that make up this chromosome. Chromosome 21 was the second human chromosome to be fully sequenced. Chromosome 21 likely contains between 200 and 400 genes. These include: †¢ APP: amyloid beta (A4) precursor protein (peptidase nexin-II, Alzheimer disease) †¢ CBS: cystathionine-beta-synthase †¢ CLDN14: claudin 14 †¢ HLCS: holocarboxylase synthetase (biotin-(proprionyl-Coenzyme A-carboxylase (ATP-hydrolysing)) ligase) †¢ KCNE1: potassium voltage-gated channel, Isk-related family, member 1 †¢ KCNE2: potassium voltage-gated channel, Isk-related family, member 2 †¢ LAD: leukocyte adhesion deficiency (symbols are ITGB2, CD18, LCAMB) †¢ SOD1: superoxide dismutase 1, soluble (amyotrophic lateral sclerosis 1 (adult)) †¢ TMPRSS3: transmembrane protease, serine 3. Effects of Chromosome 21 The effects of chromosome 21 is best felt by the conditions that are associated with its lack or mutation. These include: Cancer Rearrangements (translocations) of genetic material between chromosome 21 and other chromosomes have been associated with several types of cancer. For example, acute lymphoblastic leukemia (a type of blood cancer most often diagnosed in childhood) has been associated with a translocation between chromosomes 12 and 21. Another form of leukemia, acute myeloid leukemia, has been associated with a translocation between chromosomes 8 and 21. Down Syndrome In a small percentage of cases, Down syndrome is caused by a rearrangement of chromosomal material between chromosome 21 and another chromosome. As a result, a person has the usual two copies of chromosome 21, plus extra material from chromosome 21 attached to another chromosome. These cases are called translocation Down syndrome. Researchers believe that extra copies of genes on chromosome 21 disrupt the course of normal development, causing the characteristic features of Down syndrome and the increased risk of medical problems associated with this disorder. Mental Retardation Other changes in the number or structure of chromosome 21 can have a variety of effects, including mental retardation, delayed development, and characteristic facial features. In some cases, the signs and symptoms are similar to those of Down syndrome. Changes to chromosome 21 include a missing segment of the chromosome in each cell (partial monosomy 21) and a circular structure called ring chromosome 21. A ring chromosome occurs when both ends of a broken chromosome are reunited. Alzheimer’s Disease. Duplication in Amyloid precursor protein (APP) locus (duplicated segment varies in length but includes APP) on Chromosome 21 was found to cause early onset familial Alzheimer's disease (AD) in a french family set (Rovelet-Lecrux et al) and a dutch family set (Sleegers et al). Compared to AD caused by missense mutations in APP, the frequency of the AD caused by APP duplications is significant. ALL the patients that have an extra copy of APP gene due to the locus duplication show AD with severe Cerebral amyloid angiopathy (CAA).
