Saudization of Iraqi Families Living in Saudi Arabia Essay

Saudization of Iraqi Families Living in Saudi Arabia - Essay Example What they faced while they were settling and how they managed to make their place in the society is what the research will be focusing on. The research will mainly focus on a group of conservative families. The main area of concentration as said earlier will be on the social changes experienced as a result of moving into a more conservative Islamic state and highlighting the ability of these families to cope with the differing cultures whilst still trying to keep their identity. These families were considered to be a minority amongst the other foreigners living in Saudi Arabia. The immigrating purposes also vary from one family to another significantly and they all have their own stories to tell. Underneath the coherent appearance of these small community members there is a visible disruptive effect of the migration process seen on the surface. However this can be identified by only someone who has a close connection or understanding with the emotional side that these people face and they can reach their innermost thoughts and experiences and break the barriers of pride. I hope to be able to provide this missing connection and the feelings that have not been yet understood. Firstly I’ll analyze whether the Iraqi families adopted the Saudi way of living as part of adjustment in the society or have they been able to maintain their own distinctiveness? Secondly, what kind of problems of continuity of the two generations have they faced? Have the first generation been able to transfer their beliefs and thoughts to the second generation or has the influence of the Saudi society been more forceful and powerful than they realized. While I conducted a survey of the available information and data with regards to the migration of the Iraqi’s to Saudi Arabia, I was unable to find any detailed study using the ethnographic details available for research.

Inclusive Classrooms Essay The Success of Inclusive Classrooms Introduction Inclusive classroom is the cause of debates between families with children who have learning disabilities and those that do not have children with learning disabilities (Brehm, 2003). Inclusion can be understood as Brehm states it, Providing to all students, including those with significant disabilities, equitable opportunities to receive effective education; services, with the needed supplementary aids and support services, in age-appropriate classrooms in their neighborhood schools, in order to prepare students for productive lives as full members of society. (2003, p. 89) With the collaboration of the school and home, inclusive classrooms can be successful. Students who have learning disabilities and those who do not have learning disabilities will have the opportunity to develop in a personal fashion, social relationships, and helps students with learning disabilities become â€Å"productive†¦ as full members of society† (Brehm, 2003, p. 89). Inclusive classrooms are consistent with the law that all students should be educated in the least restrictive environment (Banerji Dailey, 1995). Results Some are opposed inclusion because they believe it will be costly for the school. One school wanted to test inclusive classrooms in their own school and to see the effects. They froze their budget so the public cannot attribute their success to an increase in expenses (Van Dyke, Stallings, Colley, 1995). Their per-pupil expenditures for students with learning  disabilities were slightly lower than neighboring schools. Since all students were included in the general education the budget was reformed (not increased) to support that. For example, the school did not have to provide separate transportation for students with special needs nor did the district have to pay private tuition for the students they could not accommodate. The school had â€Å"educational supplies† as opposed to separate supplies for the regular education classes and the special education classes (Van Dyke, et al. 1995). Another criticism is that the training needed for teachers, the workshops for school staff, and the collaboration that is needed to make inclusion successful will take a lot of extra time (Van Dyke, et al. 1995). That is true. However, the training and education teachers receive is valuable and improves their teaching to typical students and special students. The benefits that are gained by all students is worth the time (Benerji Dailey, 1995). Lastly, after a few trainings teachers learn how to run an inclusive classroom so less time is needed for workshops. If we implement the proper education for inclusion in college, teachers will begin teaching with greater skills and knowledge of how to run an inclusive classroom. Another concern is that students with learning disabilities do not necessarily do better academically in an inclusive setting compared to the special education classes. Through research it has been found that after one year of inclusive classrooms in three different districts, 54% of the students with learning disabilities learned what they were exp ected to (Zigmund, Jenkins, Fuchs, Fafard, 1995). That number was only given after one year of inclusion classroom. The success stories will keep growing if inclusion is done with the right focus and method. Classrooms are an introduction to the community that we live in. Children with disabilities need to be in regular classrooms to help them prepare for the challenges that will arise in the â€Å"real world,† (Van Dyke, et al. 1995). Segregating students puts a label on them that they are different and are therefore treated differently. But, really they are apart our community so they should be part of our schools (Van Dyke, et al. 1995). As, Van Dyke, Stallings, and Colley state, â€Å"To be truly prepared to take part in the real world as adults, children with disabilities need to be educated in language rich classrooms and to interact daily with peers who are appropriate role models† (p. 475, 1995). There are tremendous social gains for students in inclusive  e nvironments. Included students have higher peer ratings and are more accepted compared to students in the resource program (Brehm, 2003). According to the research that was done by Benjeri and Dailey (2003), students with learning disabilities improved in their self-esteem and motivation. Students also changed in their social behavior, which helped them make friends and be part of a group of friends (Benjeri Dailey, 2003). In addition, students learned to care for one another, to learn and work together. One teacher reported that while all the students were at free play, the teachers were standing around and watching them. One teacher jokingly said that the teachers were not needed anymore because the students have learned to interact and problem solve with one another without the intervention of a teacher (Benjeri Dailey, 1995). The students without disabilities also gain from inclusive classrooms. Firstly, students learned to accept all types of people no matter what they look like and value the differences of their classmates. They learned that everyone has something valuable to share. Students were less afraid of their classmates that looked or behaved differently. The students learning effected the parents too. In an ethnographic yearlong study it was found tha t students became more tolerant with others as a result of their awareness of their peers with disabilities (Staub Peck, 1994). Additionally, the study has shown that students developed positive feeling of themselves after they helped or spent time with a peer who was disabled. Their self-esteem was increased as a result of their interactions with their peers. They felt that their â€Å"helping role† with a disabled peer elevated their status in the classroom and gave them a stronger sense of belonging. The relationships between students with all different types of abilities were strong, meaningful, and long-lasting friendships (Staub Peck, 1994). We can facilitate successful inclusion in our classrooms with the right intervention, approaches, and supports. Most importantly, there must be collaboration between the school psychologist or social worker, the special education teacher, the general education teacher, the principal, and the home. Everyone has to be informed and i n agreement. When there is unity between all the parties involved in a child’s education, the child has a sense of security and can be educated in the best possible way (Van Dyke, et al., 1995). Support systems must be put in place for the teachers to turn to for advice and to help with instruction in the  classroom. The teachers should meet with a special education teacher and teacher consultant to discuss strategies for their classroom. Every classroom should have a general education teacher and a special education teacher who will be in the classroom for a part of the day and a co-teacher. Trainings and workshops should be given to educate teachers about effective inclusion and instruction (Van Dyke, et al., 1995). One up-and-coming new style of teaching is known as the Universal Design for Learning (UDL). This style of teaching meets the needs of all learners. UDL encourages teachers to create a flexible curriculum that is customized for each student. It allows students to progress from where they are and not where one imagines them to be. For an inclusive classroom, UDL is especially important because there are different learners and each child needs to learn at his o wn pace (www.udlcenter.org). The curriculum should include visual, auditory, and kinesthetic learning styles. Assistive technology such as alternative keyboards, electronic pointing devices, Sip-and-puff systems, wands and sticks, joysticks, trackballs, touch screens, should be available for any student. Assistive technology makes the classroom a friendlier place for a student who needs it. UDL offers different ways for students to express themselves and what they have learned. Students learn how to self-regulate their emotions and motivations. They don’t just learn information rather, they learn skills in how to learn and process information. They also expand their executive functioning which helps them set goals for themselves, monitor their progress, and control impulsions (www.udlcenter.org). Discussion Based on the research that was read, inclusion is an ideal way of teaching our children about the world and social relationships. The classroom is a model of a child’s community. Every child belongs to a community and so does every child deserve the chance to receive the best education in the least restrictive environment (Van Dyke, et al., 1995). Inclusive classrooms teach the skills and life lessons to all the students of all types of abilities. Students develop healthier self-esteems, learn how to interact with each other and problem solve together. Students become more accepting of others differences and learn to look out for each individuals unique traits. Inclusion removes the labels that make others different and not good enough.  It lets the classroom be a growing place for all no matter the disabilities (Van Dyke, et al., 1995). The key to Inclusion is communication. The school and the home must be involved in aspects of the child’s education . Teachers need to be trained and taught how to be effective in an inclusive classroom (Van Dyke, et al., 1995). Additionally, UDL will help the curriculum be shaped to help each child succeed in their own way (www.udlcener.org). The limitations of this paper is that it does not state what types of disabilities should be included in the classroom and at what level of functioning a student must be to be included. The paper does not discuss whether a pull out program may be needed or not and to what extent it can be used. References: Benerji, M., Dailey, R. A. (1995).

Poems for the Eye Are Not Merely for the Sake of Eye :: English Literature Essays

Poems for the Eye Are Not Merely for the Sake of Eye What is poetry? Pressed for an answer, Robert Frost made a classic reply: â€Å"Poetry is the kind of thing poets write.† In all likelihood, Frost was not trying merely to evade the question but to chide his questioner into thinking for himself. A trouble with definitions is that they may stop thought. The nature of poetry eludes simple definitions. Definitions will be of little help at first, if we are to know poetry and respond to it. We have to go to it willing to see and hear. To a particular poem, thousands of readers will have thousands of understandings. A poem can please us in many aspects. We usually concentrate our attention on its sound, wording, and figure of speech. In fact, a poem in stanzas can please us by its visual symmetry. This kind of poems is usually called the poems for the eye including spatial free verse and picture poems. Though many poets seem hardly to care about it, enough importance should be given to the visual element of poetry. At least some of our pleasure in silently reading a poem derives from the way it looks upon its page. Poems for the eye can be divided into two types. One kind is the visual quality predominates the whole poem; the other is the visual remains subordinate to the aural and other elements of the poetry. There are indeed some spatial poems that can bring us pleasure through their words arrangement. And far from being merely decorative, the visual devices of a poem can be meaningful, too. For examples: This is William Carlos Williams’ poem that describes an energetic bellhop runs downstairs. Beside the words sound like that man is running downstairs, the appearance of the whole poem is like the stairs. This is not only good onomatopoeia and an accurate description of a rhythm; the steplike appearance of the lines goes together with their meaning. This kind of appearance or words arrangement makes the common words â€Å"ta tuck a† vivid. The same with the following Kenneth Patchen’s (1911-1972) poem: The ball bumps down the steps†¦ In the two poems above, the visual quality dominates the meaning of the whole poems. You can say that the shape of the words arrangement overweighs the meaning of the words. But it does bring us pleasure. It is more interesting and meaningful and stronger than just say, â€Å"ta tuck a†¦Ã¢â‚¬  and â€Å"The ball bumps down the steps†¦Ã¢â‚¬  Maybe this is one of the great charms of this kind of poems.

Reasons Why Investment Trusts Trade at a Discount

Abstract The fact that investment trusts and close-end funds in general trade at a discount has elicited debates among financial scholars and practitioners, often referred to as the closed-end puzzle. Based on this, this paper explores and explains some of the reasons that investment trusts trade at a discount. It also provides an in-depth explanation of characteristics of close-ended funds and conditions that lead to the classification of the share price as either a discount or a premium. Investment trusts trading at a discount are those trading at prices that are below their net asset value. Those trading at a price higher than the net asset value are considered as being sold at a premium. Some of the main reasons that are explored in this paper include miscalculation of the net asset values of the investment trust, taxes on realized capital gains, agency costs, managerial abilities and investor sentiment. Even with the explanations that are provided in this paper, the closed-end fund prize puzzle continues to be debated upon and researched. Introduction The fact that investment trusts often trade at a discount is an aspect that has drawn interests from academics and practitioners in the field of finance. To have a better understanding of these reasons, it is ideal to provide an exhaustive definition of investment trusts. Investment trusts, which are typical to the United Kingdom, are defined by Barnhart and Rosenstein (2010) as types of investment firms that are formed with the primary aim of holding securities for other companies and the obtainment of capital from the public issue of shares trading on the stock market. They are also referred to as closed-end funds because they only offer a fixed quantity of shares that new investors can purchase from already existing shareholders (Hartzell et al., 2006). The prices of shares of investment trusts are determined by the forces of supply and demand in the share market. As a consequence, there are incidents where the price of a share may either be higher or lower than its net asset valu e. Whenever a share trades at a price that is higher than its net asset value, it is considered to be trading at a premium. On the contrary, if a share trades at a value that is lower that its net asset value, it is considered to be trading at a discount (Berk & Stanton, 2007). In this regard, this report intends to discuss reasons why they trade at a discount. Reasons for discounting Investment Trusts One main characteristic of investment trusts and closed-end funds in general is the fact that they are permanent capital ventures and thus, the shares’ supply is fixed (Chan et al., 2008). Numerous attempts that have been made by researchers and practitioners to explain the investment trust discounts, and have resulted in conflicting results, commonly referred to as the closed-end fund puzzle. Even though these funds are known to trade at discounts, it is important to note that newly opened investment trusts and closed-end funds in general, usually begin trading at a premium of approximately 10% of their net asset value. After their initial premium trading, they shift towards trading at a discount that is at average rate of 10% within the first 120 days. After which, discounts remain substantial. In case closed-end funds are closed or terminated, there is an increase in their share prices, which in turn eliminates the existent discounts (Cherkes et al., 2009). Explanations for investment trust discounts that have been made by researchers include the risk of liquidity, the past and future performance of shares on the market and the miscalculation of the fund’s net asset value. Investor sentiment is also another reason for discount trading in investment trusts (Yanran & Liyan, 2007). This section intends to provide a more in-depth discussion of these reasons. Misestimating the Net Asset Value (NAV) This reason has been pointed out by Halkos and Krintas (2006), who argue that such miscalculations of the NAV can result from a possible accumulation of capital gains illiquid assets that had not been realized. The reason why funds with high capital appreciations that have been unrealized ought to trade at a discounted share price is that potential holders of such funds will assume a potential tax liability. In a research that was carried out by Kousenidis et al. (2011) on the effect of liquidity on closed-end funds, he established that there is a possibility of illiquid assets to be traded at a discount to provide higher expected returns. In support of inaccuracy of NAV measurement as a reason for discounts in closed-end fund trading, Yanran and Liyan(2007)suggested that when closed-end funds own large amounts illiquid assets or restricted stock that are not fairly trading in the market, their NAVs can fail to provide an accurate reflection of their true value. As a consequence of t his, the shares might either trade at a lower or higher value than the NAV. Investment trust discounts are also affected by restricted stock holdings. However, given that such holdings are often quite small or at a zero value, they do not hold as valid reasons for investment trusts trading at a discount. For investment trusts, there is usually no assurance that there will always be an available market. Therefore, this lack of an assured redemption of shares makes their valuation to be discounted. In addition to this, investment trusts that hold relatively liquid securities are valued lower than their net asset values (NAVs) at the marketplace (Cherkes et al., 2009). Putting appropriate measures in place to avoid miscalculation of the trust net asset value is vital to solve this issue. Agency Costs and Managerial Ability Discounts in closed-end funds could be a reflection of poor performance in the management of the fund or an overcharge of management fees (Bradley et al., 2010). Agency costs may also vary according to the agency issues or conflicts that may occur due to different interests between agents and principals. Managerial abilities have also been listed by researchers as being among the main factors that determine whether investment trusts can trade at a premium or a discount. The theory that investment trusts can trade at a discount if the managers charge a fee was originally proposed by Boudreaux in 1973 (Berk & Stanton, 2007). He suggested that if fund managers charge investors a fee but fail to add value to their investments, then the value of the fund is likely to be less than its NAV. In a case where managers add value to the investment trust, the reason why it might trade at a discount is when investors are made to believe that the funds’ managers are not good at investing the ir funds. If investors believe that their money is being managed by people who are good at selecting viable investments, then the fund will trade at a premium. In a research carried out on the ownership of closed-end funds Cherkes et al.(2009) established that investment trusts with larger percentage of insider ownership are likely to trade at higher discounts. This is because investors of funds that are selling at higher discounts stand a chance of receiving windfall gains in case the funds undergo immediate liquidation at their net asset value. He also established that higher expense ratios lead to higher discounts of funds because management fees are considered as being deadweight losses. Thus, discounts are used to represent the capitalization of the management fees value. Management of trusts also affects their future performances in the market, which also determine whether investment trusts are to be traded at a discount or premium. Halkos and Krintas (2006) argue that in case s where investment trusts are managed in a highly professional manner and with a positive track record, investors may have the will to pay a premium for a share of the funds. This is also due to the fact that such trusts are often expected to maintain their superior performances in future. On the other hand, funds that are expected to underperform in the market are expected to be traded at higher discounts, mainly because of the scepticism that potential investors may have for the fund (Berk & Stanton, 2007). Estimation of future performance of investment trusts can be done by comparing trends in the NAV, which are estimated on a frequent basis. It can also be done by evaluating the managerial capabilities of the fund. It can be thus argued that investment trusts whose management has a good reputation tend to perform well in the market and therefore, trade at a premium. On the contrary, poorly managed trusts fail to thrive in the market and therefore, are likely to trade at a discou nt. Taxes Another reason why investment trusts trade at a discount is taxes. According to Jin(2006), full taxes on the realized capital gains of a fund are paid for by the current shareholders, even though the highest percentage of their gains was accumulated before the investors bought the shares. Based on this, it can be argued that funds whose accumulated gains are large ought to trade at a price lower than their NAVs also suggests that investment trusts that have a high appreciation of unrealized capital sell at discounts because holders of such funds assume potential tax liabilities that depend on the holding periods of the investors. Berk and Stanton (2007) posit that discounts in closed-end funds are partially caused by the fact that investors usually lose valuable opportunities to trade tax because of holding shares in closed-end funds. Some of the tax trading approaches include individual portfolio movement. On comparing British and U.S. closed-end funds, Cherkes et al.(2009) establis hed that British funds do not have the freedom of distributing capital gains as the US funds do. In addition, shareholders have no liability in case the invested capital gains tax, except if they decide to put the holdings that they have in the fund up for sale. Yet U.S. and British closed-end funds behave in a quite similar manner. Thus, it can be concluded that discounts in investment trusts and closed-end funds cannot be explained based on country-specific tax factors. Investor Sentiment Many researchers have focused on the aspect of investor sentiment as a reason for discounts in investment trust trading. This hypothesis was proposed Lee, Shleifer and Thaler in 1991 (Yanran & Liyan, 2007). According to them, premiums and discounts in closed-end funds are determined by the attitudes of opinions that investors have about them. To explain this hypothesis, two kinds of investors are identified. These are the noise investors and rational investors. Whereas the expectations of rational investors on their asset returns are rational, noise investors’ expectations are influenced by sentiment. They have the tendency of either overestimating or underestimating the expected returns on investment. Therefore, when investment trust shares are traded, noisy and rational investors make their investments based on their respective judgments. Due to the risk associated with assets and the fact that every investor is risk averse, closed-end funds ought to trade at equilibrium pri ces that reflect opinions of the noisy and rational investors, which are often discounts. A proposal was made by Halkos and Krintas (2006) that noisy investors tend to concentrate more on the closed-end fund ownership than on the ownership of the underlying assets of the funds. Pessimism by noise traders on the future of fund drives down its price to a value lower than its NAV. This causes rational investors to avoid the buying the fund’s shares because of the risks associated with trading the funds at a discount. Chan et al. (2008) also argue that the sentiment of noise traders is stochastic and, therefore, cannot be accurately predicted by rational traders. Particularly, it is impossible for rational investors to make a perfect forecast whether noise investors will either be pessimistic or optimistic at the time that they intend to sell their assets. Due to the fact that rational traders are careful about the prices with which they will resale their assets, the unpredictabl e nature of noise traders’ sentiment increases the level of risk on the assets they intend to trade (Kousenidis et al., 2011). The biggest risk associated with noise investors is that they will be pessimistic at the time when rational investors intend to sell their assets, causing a drop in prices. Since there is always a risk of an adverse sentiment shift, the possibility of trading shares at a discount is always existent (Yanran & Liyan, 2007). Conclusion This paper has provided an in-depth explanation of some of the reasons why investment trusts usually trade at a discount. Apart from this, other aspects of investment trusts have been explained. One of the main characteristics of investment trusts that has guided the establishment of reasons discussed in this paper is that it is a closed-end fund. This means that supply of shares is fixed, regardless of the market dynamics. Therefore, fluctuations of these funds that result into premiums or discounts are mainly caused by demand factors. The main reasons why investment trusts trade at discounts include the attitudes that investors have on the fund, commonly referred to as investor sentiment, agency costs and managerial abilities, taxes and miscalculation of the net asset value of the fund. However, the factor that is contented upon by most researchers in this field of finance is investor sentiment, which is a behavioural approach of understanding this concept. Some of the other reason s that have been cited in several other researchers include the institutional ownership and performance of the trust in the market. In future research, a more specific research could be carried out by focusing on a specific investment trust in the UK. References Barnhart, S.W. & Rosenstein, S., 2010.

Ball bounce higher when it is warmed up Essay

Prediction I predict that for this experiment the higher the temperature, the more the ball will bounce. I put this down to the temperature is raised, the particles inside will gain energy therefore the higher the ball will bounce. Equipment For this experiment I will use the following equipment to do this experiment: – 1. Beaker 2. Bunsen burner 3. Splints 4. Tripod 5. Gauze 6. Thermometer 7. Squash Ball 8. Paper Towels 9. Meter Ruler 10. Tongs 11. Stop Clock 12. Safety goggles. Method Choose one yellow spot squash ball. This will be used throughout the experiment to ensure that the ball is made of the same rubber and same size. The experiment will be carried out on the hard floor tiles of the science laboratory. The area will be clean to ensure there are no irregularities on the surface. The ball will be heated to the required temperature by placing it in a beaker of heated water for one minute. To ensure the human body does not affect the temperature, tongs will handle it. Temp (? C) Temp (Kelvin). Results I am going to work out pressure and predicted hang time using the following formulas. This is how to work out pressure; P1 is Pressure 1, which is always 1. T1 is Time 1 and T2 is Time 2. This number changes as you work out To work out predicted hang time you use this formula. In this formula P1, P2 etc are Predicted hang time. This number changes as you work out   Temp (Kelvin) Pressure Predicted Hang time Actual Hang time. Analysis From my graph I can see that the predicted hang time and the actual hang time differ greatly from 293 Kelvin onwards, the real hang time increases quite dramatically where as the predicted hang time escalates only a bit. From doing this experiment I have found out that when pressure is increased by raising the temperature inside a squash ball, the particles gain more energy and can reform more quickly from its impact on the surface. My actual hang time results show this. My prediction was correct in the sense that my theory of the particles gaining energy worked. My predicted hang times unfortunately were not correct. They were not a good match to my actual hang time results; I put this down to another variable. The other variable I believe is elasticity of the squash ball’s material. I believe that if the ball has high elasticity then the deformation (formed by the impact of the ball hitting the surface) of the ball will be bigger and because it is bigger it will reform more quickly and bounce higher. The energy at the start of the ‘dropping’ process gravitational potential energy, but as the ball speed increases this changes to kinetic energy. When the ball reaches impact, kinetic energy changes to elastic potential energy and a bit of thermal and sound energy. This thermal and sound energy remain at a low constant throughout the rest of the balls ‘bounce back’. When the ball reforms it bounces up and gravitational energy increases to its previous level. Evaluation I think I conducted my experiment to a high standard and there were no major anomalous results (except the hang time and predicted hang time results). Each result had an average difference of 7. 9 between the next one, this average was brought down drastically by the 2. 8 difference between the first two results (38. 4 and 41. 2). If I were to make any improvements to the method and equipment of this experiment I would: – 1. Change the way the ball was dried as I think a more sophisticated way could be used to prevent human error. 2. Use a different way of timing the balls impact to the ground; a touch sensitive timer mat would work well. 3. I would try different surfaces on which the ball lands on, this could be thought of as another variable I could develop. If I were to do this experiment I would change the temperatures to smaller differences i. e. 273 Kelvin, 278 Kelvin etc. to see if I could find an ideal temperature that had a good enough ‘bounce’ to help develop work into elasticity of the balls material. If I were to develop this experiment further I would test elasticity. To test this I would experiment with a range of different squash balls. I would cut them into equal narrow pieces and use a Newton spring to test how much the piece of squash ball could hold and how long it would take to reform back to its original shape, for this I would use a Newton spring and stop clock. All in all I think I conducted myself well on this experiment and have learned a lot.

Making certain that your kid is influenced by positive function theoretical accounts will assist them to accomplish more in life. Harmonizing to the Oxford Dictionary, the term function theoretical account by and large means any individual who serves as an illustration and whose behavior is emulated by others ( Stevenson A ; Lindberg, 2010 ) . Harmonizing to Christine Hulme states that, Role theoretical accounts are a really powerful force for puting and accomplishing productive ends. Children heads are of course developed to larn from the experience of others. Whether the experience is captured in the signifier of books, narratives, or games the experience of others offers a really powerful manner to make a higher degree of success. Why do we utilize function theoretical accounts, to assist kids larn the accomplishments needed to be a motivated self-learner? This is because patterning the behavior, ideas, and attitudes of successful people has been shown to assist a individual become more successful. Hulme farther states that research has shown that about all of the successful people today had a series of function theoretical accounts. The leaders of today all had great function theoretical accounts that inspired them to great highs . The choice of good function theoretical accounts serves as a usher for them to do the most out of their abilities. By presenting your kid to function theoretical accounts for all facets of their lives, you are turning their imaginativeness. With good function theoretical accounts, you get your kid to conceive of success. Harmonizing to the cyberspace web site, more4kids.com: Positive function theoretical accounts are of import in the turning kid s life. They are extremely of import for kids psychologically, assisting to steer them through life during their development, to do of import determinations that affect the result of their lives, and to assist them happen felicity in ulterior life . When kids are turning up, they look to function theoretical accounts for inspiration and utilize this as a design for how they should act when they get older. This is likely a survival map designed to assist us to mime the traits of those successful members of our society and thereby assist our kids to be successful excessively. In add-on, the More4kids web site farther stated that at the same clip, in ulterior life, its idea that kids felicity is really much based on their perceptual experience of how their life should or could be and the spread between that and how it is in world. In other words, it is endeavoring for that same sort of success and accomplishing it that brings kids felicity or otherwise when they get older. This is called actualization harmonizing to Goldstein. As such so, holding the right function theoretical account will guarantee that kids learn to be successful and adaptative in ulterior life, and that they are happy when they are older holding achieved that purpose. It s really of import to acquire the right 1 for yourself, and to supply one for your kid or kids. Harmonizing to Clarke, a junior editor, she stated that: Childs are exposed to a figure of different function theoretical accounts in Jamaican and in the Caribbean on a whole. On one manus she stated that, the sad thing is, non all function theoretical accounts today are positive.A For illustration, a character on a Television show or a film that a child thinks is cool or neat.A A public figure or a scoundrel might do a kid privation to make the things that this individual does. A Even adolescents imitate negative function theoretical accounts like older kids in high school or pack members.A A adolescent might be pressured into making something all the other adolescents do. Many people have function theoretical accounts ; all people do, even if they do nt cognize it. On the other manus Clarke added that The most obvious function theoretical accounts for any kid or kids are their parents, followed by other immediate household, household friend and professionals such as instructors, attorneies, physicians, merely to call a few . First, parents are the biggest function theoretical accounts because they ever teach their kids to remain out of problem and warns them of the effects that comes with doing incorrect decisions.A But they besides teach their kids about the good wagess and where you can travel when you make the right decisions.A In add-on, parents portion personal narratives of when they made incorrect determinations in their life, and kids learn from that. Every kid asks their parents for advice and even if they do nt, they still follow their parent s ways.A Parents have a large function in their kid s life and some parents do nt take it seriously.A If parents do nt take their womb-to-tomb undertakings, with their kid, earnestly the kid wi ll believe that their parents do nt care about them.A The kid will travel out and make bad things for attending, and all they will have is negative attending. If the parent neglects their kid or if a kid receives negative attending from their parents, the kid will look up to person else to accomplish positive or negative attending. In contrast, a good behaved and a high achieving kid must hold a good function theoretical account. Second, instructors tend to be function theoretical accounts for most, if non all of their pupils because most of their yearss are spent at school in the schoolroom with their instructors so they become attached to the instructors even more than their parents in the place. In add-on, there are other professionals that kids imitate to be function theoretical accounts. Some of these persons are psychologists, counsel counsellors, attorneies, physicians and nurses. They look up to these professionals because they are successful people who have worked difficult to accomplish their dreams and aspirations in life. Third, athleticss stars and jocks are function theoretical accounts for kids today.A Athletes everyplace spends clip working with charitable organisations and donate to the cause of destitute children.A They are healthy with their mental determinations and physical well being.A Athletes and athleticss stars are usually fleet, energetic, active and flexible and kids tend to be fascinated by these persons. They make kids want to be like them in many ways because they are really successful people. Some kids imitate sketch fictional characters to be their function theoretical accounts. However, some sketch characters are nt good function theoretical accounts. There are a few characters and plans that are positive and they teach of import lessons. For illustration on Discovery Kids there is Turning Up Creepy and Grossology. Both are positive shows, the first trades with being different, holding a household that is different and being comfy with who you are. The 2nd is a positive manner of covering with emphasis and jobs that pop up in life, most of which are related to bodily maps, but it is a brother/sister squad that saves the universe in each episode. This may be wholly realistic but is it better than holding your kids watch senseless sketchs that teach force and bad behavior. Harmonizing to the article, The Importance of Role Models , states why it s so of import in these functions to supply a good function theoretical account: As kids will be copying your behaviour, that means that if you smoke, you can anticipate your kid to take up smoking either now or later in life. If you swear meanwhile they excessively will curse. You are their bluish print for life. At the same clip though they will happen other function theoretical accounts elsewhere as they grow older, merely as you likely have different function theoretical accounts today. If you re taking a function theoretical account for yourself or for a kid so, it s of import to do certain that they have good ethical motives and do nt indulge in suicidal behavior. A good function theoretical account should be person difficult working, originative, free thought and moral. ( Thomas, 2011 ) While you ca nt take function theoretical accounts for your kids as such, you can do certain that they are exposed to a better choice to take from. For illustration promoting your kid to read Superman instead than The Punisher ( who murders his enemies and has a general bad attitude ) might hold a good impact on the manner they turn out. Similarly, if you find that they re hanging about in what you deem to be the incorrect crowd so these can function as bad function theoretical accounts. To work out this job, seek presenting them to other groups and promoting them to mix more while maintaining them at place more darks they want to travel off with their incorrect group. Meanwhile if you find that your life is presently non traveling the manner you want it to and you are turning distant from your friends and household, so look at your ain precedences and who your current influences are. At the same clip though it s of import non to set function theoretical accounts on a base. If they re human and existent so they need to be recognized as such. Everyone makes errors and so to follow anyone blindly is a error. Recognized that this is a guide for you and non person you have to follow precisely. One good manner to forestall this from being a job is to hold multiple function theoretical accounts. This manner if one of them does something you do nt hold with so you ll still hold others you can look to. At the same clip it can be reasonable to hold different function theoretical accounts for different countries of your life. Harmonizing to the Benefits of Role Models for Kids , the benefits of exposing kids to positive function theoretical accounts are important in many ways. Some of these ways are First, to heighten behavior and to expose positive attitudes and idiosyncrasy so your kid will non expose unacceptable behavior. Second, exposing kids to positive function theoretical accounts serve as a usher for kids to do the most out of their abilities. Third, acquiring your kid or kids to conceive of success by puting and accomplishing positive and productive ends that they would desire to accomplish in life with the betterment in calling planning and determination devising. Fourthly, steering kids to develop maximal potency in all facets of their lives and eventually geting the accomplishments needed to be excel in life and besides in academe. In drumhead, to assist do certain that you are being a positive function theoretical account to your kids, make certain that you portion your values with your kids, this means that you talk to your kids about where you stand on issues such as drugs, smoke, sex, homeless, poorness, and faith merely to call a few. Following, demo your kids that you are confident and happy with who you are. Your kids need to see that you have self esteem. If they see that ma and pa are happy with who they are, so they are more likely to be happy with who they are. Besides along with that, demo them the importance of being independent. Be yourself and be happy with who you are. Deal with your emphasis in positive ways. Part of being human agencies covering with emphasis on a day-to-day footing. Some yearss there is more stress than others. You do nt hold to conceal emphasis from your kids, alternatively demo them how to cover with it. Let your kids know about your successes and your failures. Disappointments are merely every bit much a portion of life as successes are. Failing does nt do you a bad individual, it gives you the opportunity to larn how to make something better. Let your kids know that you love them no affair what. Do non presume for one minute that kids know this innately. Do nt experience bad if you child inquiries it, take it as an chance to brush them in your weaponries and state them how much you love them and how unbelievable they are. A concluding tip for parents on being a positive function theoretical account for your kid or kids is to do certain you are involved in their lives. Talk to them about their twenty-four hours at school, what they learned and what they did. Know who their friends are. Know who your kid is out with, who are their function theoretical accounts. Take a expression at who they hang out with, who they talk about the most and who they watch on telecasting. Role theoretica l accounts are the most of import thing in a kid s life when turning up.A Everyone needs person to look up to.A You could be a function theoretical account some twenty-four hours ; you likely are one now to a younger brother, sister, comparative or friend and your pupils.

But most of all it's an educational endeavor to empower and inform, allowing individuals to know that often times there is an existing pattern of attitudes, ideas & behaviors that can allow them to be warned regarding the person they are involved with has potentially life threatening issues:. Young women/teens mistake aggressive and abusive behaviors as serious displays of love. We are a society of people charged to protect and care for the innocent. We must be prepared to let those who harm women, children and the elderly know that society will no longer tolerate this type of behavior. (Jeffrey Dunmore, DV Specialist, Men in Transition, 2013). The Impact of Domestic Violence The Impact of Domestic Violence Violence is all too prevalent worldwide today. It seems every time you turn on the news someone, somewhere, and everywhere there are incidents of violence. Our schools are unsafe, the shopping malls are unsafe, home invasions, and even those romantic make out places, such as parks and â€Å"Lover’s Lane†, are no longer safe. Domestic Violence however, is a different kind of violence and is generally endured in silence. Women will deny being battered, for various reasons, children will become silent and live with pent up anger for most of their lives, and the elderly may be incapable of reporting the violence, perhaps based on their need for companionship. Even our immigrants remained silent for fear of deportation, despite the fact they may be in this country legally. (dcadv.org, 2008) Women, children and yes sometimes men fall victim to insidious violence. Domestic violence is insidious not because of the physical aspects it entails, such as the black eyes or br oken arms generally noticed, but because it is literally deadly. Violence in the home may also impact an individual psychologically, economically and emotionally. Many relationships base love on sex and financial security. Many women will not leave based on financial insecurity and self-esteem issues. The Bible clearly states what love is in 1 Corinthians 13:4-7,† Love is patient and kind; love does not envy or boast; it is not arrogant or rude.† It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.† (EVS www.openbible.info/topics/domestic violence-_and-_abuse‎, 2001 by Crossway Bibles) Types of family violence experienced â€Å"Husbands, love your wives, and do not be bitter towards with them†. (Colossians 3:19). â€Å"Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered â€Å" .(1 Peter 3:7). www.openbible info New Living Translation (NTL) Domestic violence can manifest itself in many ways, much like addiction. Many believe addiction is about drugs, however addiction is an obsessive and compulsive disorder, that once a person starts they are unable to stop on their own free will. (N.A, Basic Test.1965).

Medieval Christmas Traditions

Medieval Christmas Traditions Among the Pagan traditions that have become part of Christmas is burning the yule log. This custom springs from many different cultures, but in all of them, its significance seems to lie in the iul or wheel of the year. The Druids would bless a log and keep it burning for 12 days during the winter solstice; part of the log was kept for the following year when it would be used to light the new yule log. For the Vikings, the yule log was an integral part of their celebration of the solstice, the julfest; on the log, they would carve runes representing unwanted traits (such as ill fortune or poor honor) that they wanted the gods to take from them. Wassail comes from the Old English words waes hael, which means be well, be hale, or good health. A strong, hot drink (usually a mixture of ale, honey, and spices) would be put in a large bowl, and the host would lift it and greet his companions with waes hael, to which they would reply drinc hael, which meant drink and be well. Over the centuries some non-alcoholic versions of wassail evolved. Other customs developed as part of Christian belief. For example, Mince Pies (so called because they contained shredded or minced meat) were baked in oblong casings to represent Jesus crib, and it was important to add three spices (cinnamon, cloves, and nutmeg) for the three gifts given to the Christ child by the Magi. The pies were not very large, and it was thought lucky to eat one mince pie on each of the twelve days of Christmas (ending with Epiphany, the 6th of January). Food Traditions The ever-present threat of hunger was triumphantly overcome with a feast, and in addition to the significant fare mentioned above, all manner of food would be served at Christmas. The most popular main course was goose, but many other meats were also served. Turkey was first brought to Europe from the Americas around 1520 (its earliest known consumption in England is 1541), and because it was inexpensive and quick to fatten, it rose in popularity as a Christmas feast food. Humble (or umble) pie was made from the humbles of a deer the heart, liver, brains and so forth. While the lords and ladies ate the choice cuts, the servants baked the humbles into a pie (which of course made them go further as a source of food). This appears to be the origin of the phrase, to eat humble pie. By the seventeenth century, Humble Pie had become a trademark Christmas food, as evidenced when it was outlawed along with other Christmas traditions by Oliver Cromwell and the Puritan government. The Christmas pudding of Victorian and modern times evolved from the medieval dish of frumenty a spicy, wheat-based dessert. Many other desserts were made as welcome treats for children and adults alike. Christmas Trees and Plants The tree was an important symbol to every Pagan culture. The oak, in particular, was venerated by the Druids. Evergreens, which in ancient Rome were thought to have special powers and were used for decoration, symbolized the promised return of life in the spring and came to symbolize eternal life for Christians. The Vikings hung fir and ash trees with war trophies for good luck. In the middle ages, the Church would decorate trees with apples on Christmas Eve, which they called Adam and Eve Day. However, the trees remained outdoors. In sixteenth-century Germany, it was the custom for a fir tree decorated with paper flowers to be carried through the streets on Christmas Eve to the town square, where, after a great feast and celebration that included dancing around the tree, it would be ceremonially burned. Holly, ivy, and mistletoe were all important plants to the Druids. It was believed that good spirits lived in the branches of holly. Christians believed that the berries had been white before they were turned red by Christs blood when he was made to wear the crown of thorns. Ivy was associated with the Roman god Bacchus and was not allowed by the Church as decoration until later in the middle ages when a superstition that it could help recognize witches and protect against plague arose. Entertainment Traditions Christmas may owe its popularity in medieval times to liturgical dramas and mysteries presented in the church. The most popular subject for such dramas and tropes was the Holy Family, particularly the Nativity. As interest in the Nativity grew, so did Christmas as a holiday. Carols, though very popular in the later middle ages, were at first frowned on by the Church. But, as with most popular entertainment, they eventually evolved to a suitable format, and the Church relented. The Twelve Days of Christmas may have been a game set to music. One person would sing a stanza, and another would add his own lines to the song, repeating the first persons verse. Another version states it was a Catholic catechism memory song that helped oppressed Catholics in England during the Reformation remember facts about God and Jesus at a time when practicing their faith could get them killed. (If you would like to read more about this theory, please be warned that it contains graphic descriptions of the violent nature in which Catholics were executed by the Protestant government and has been refuted as an Urban Legend.) Pantomimes and mumming were another form of popular Christmas entertainment, particularly in England. These casual plays without words usually involved dressing up as a member of the opposite gender and acting out comic stories.

What is the burden of proof for civil case and a criminal case Assignment

What is the burden of proof for civil case and a criminal case - Assignment Example This is owing to the fact that the defendant stands to be jailed and lose other civil liberties in criminal cases. Owing to the penalties that are associated to criminal cases, the prosecution is charged with the duty of more than proving that the defendant committed the crime in question, it must be beyond reasonable doubt (Finkelman, 2006). In other words, the evidence presented against an individual should be adequate that no rational person can question their guilt. In addition to proving the guilt of the accused, the prosecution is required to prove that there was intention to commit the crime. In instances where the prosecution does not satisfy both requirements, the accused cannot be convicted. When dealing with a criminal case the burden of proof is on the state at all instances. It is upon the state to prove the defendant’s guilt. On the other hand, the defendant is viewed to be innocent and has nothing to prove (Finkelman, 2006). However, there are exceptions in instances where the defendant is under duress or self-defense and instances of insanity. Furthermore, the state should establish that the defendant satisfied every stipulation in the appropriate definition of crime. In spite of the fact that the concept is mostly linked to criminal litigation, it is applicable to civil litigation that relates to personal injuries, contracts and property issues. The plaintiff is required to have sufficient evidence to back their accusations while on the contrary the defendant must prove these accusations to be wrong. In civil cases, the burden of proof is originally on the plaintiff. However, there are various technical cases whereby the burden of proof is tranferred to the defendant. For example, in situations where the plaintiff has filed for a prima facie case, the burden of proof is tranferred to the defendant (Finkelman, 2006). In civil cases, the plaintiff wins if

When people travel, the need for an industry such as hospitality enters. They need to stay in hotel and eat in restaurant. Perhaps travelers are not even aware of it, but they are patronizing hospitality industry. When they step out of the comfort of their own abode, and start to travel they should be rewarded by good hospitality of the places they have chosen to stay.

People who are involved with this kind of business must possess high quality of hospitality, flexibility, and charm. It should be kept in mind all the time that these travelers are probably strangers in this place, and quality of service would mean a lot to them. Travelers often times come back to a place because they experience great accommodation in establishments they went to. Good service, being polite, good food and clean premises are all associated to a good travel experience. When tourists bid their goodbyes they will take with them the memory of your hospitality. Therefore, it is of an utmost importance that we have the best knowledge, and that we have got the best training in the area of what we are doing when we enter this field of industry. The history of hospitality industry can be traced back to the Colonial Period in the 17th century. There have been many considerable changes from years that passed till the present day. The industry has survived World Wars, the Depression Era, and many more.

Contemporary Literature Essay Example | Topics and Well Written Essays - 500 words

Contemporary Literature - Essay Example Indeed, American literature during this time is highly coherent to its culture (Daly 187). One of the most prominent writings during this time is that of Captain John Smith, one of the greatest leaders of the English colonizers who played a huge role in the stabilizing the colony. Perhaps, because of his endeavor, his works, distributed in pamphlets, concern mostly the difference between the two cultures emphasizing the self-righteousness and greed of Americans – something which was contradicted by the works of William Bradford and John Winthrop who reported more on the selflessness of men and women of that time (Gura 339). True enough, the ideas of cultural historians and critical theorists have dominated the American Colonial literature (Gura 338). Moreover, American colonial literature is also marked with religiosity. It is noteworthy that another batch of British colonizers arrived in order to introduce a religion in America that is separate from the Church of England. The se Puritans have influenced American writers who embraced the religion to write something theological in nature.

Discuss how can the cloning of linker histones help to understand Essay

Discuss how can the cloning of linker histones help to understand their function in cells - Essay Example Histones have a characteristic ‘histone fold domain’ consisting of structural motif known as ‘helix-turn-helix and that are three alpha helices that all connected by loops. Each of the histones fits perfectly with their counterpart to form heterodimer structures that assume the appearance of a hand-shake. The histone cell structures are buried inside the core structure of the nucleosome. The histones have conspicuous N-terminal tails protruding out of the compact structure. Often the terminal tails are subjected to several post-translational modification that include methylation, ubiquitination, acetylation, phosphorylation, and many more (Xie 2009). It is the combination of the marks they get through the modification processes, and that determine the factors that bind to the region of DNA and in the long run regulation the expression status of the given locus. The multiple loci occurring as distinct clusters on different chromosomes are where the histone genes typ ically transcribed. Histone proteins have their individual repertoire of variants distinct in the sequence of their amino acid mostly in the protruding N-terminal region. The expression of the variants, which is dependent on the type, can either be replication-dependent or replication-independent. As will be discussed in a dedicated section below, their main function is to mark specific regions of the DNA by replacing canonical histone from the nucleosomes present and the particular site. This stress on distinct regions in the genome has a noteworthy part in recruitment of diverse factors to that site occasioning differential treatment. It is this mechanism that lays the foundation for creation and development of an epigenetic ‘memory’. The dyad axis of symmetry that is where the exiting and the entering DNA duplexes cross has been a long held outlook of the most likely location for the binding of the linker histone to the nucleosome core particles.

Business Ethics and Social Responsibility and Its Impact on Efficiency Research Paper

Business Ethics and Social Responsibility and Its Impact on Efficiency - Research Paper Example As a consultant for this firm, the report made by the ABC consultations will also discusses the basic features that are the most prominent for the organizations, the social responsibility,and how these actually shape the overall strategic planning to eventually achievevalue creation as well as increased profit. The SR is a solid framework to discover and discuss relationships that reside in the business-society, which can be achieved by examining the corporations and their social impact (Carroll, 1991; Wood, 1991).There have been many researches that have encouraged open attitude directly related to the efforts that can generate a new way of thinking for the corporations as well as thebusinessesthat compete in the global society. The first part of thereporthighlights an introduction of the topicthatspecifies the subject as well as the basic purpose of the report. Then stated, are the research findings from the investigation, along with the analysis of the gathered information to fina lly end with recommendations. The paper therefore examines the features and tactics required by the XYZ Company on how these can be mixed in the practices of the organizations. The report will also highlight how business ethics helps in developing the social capital,as well as the practices that help the organizations sustain in the competitive environment of the global environments. The report ends with the eight basic characteristicsneeded to attain efficiency that is the responsibility of the owners as well as the managers of the XYZ organization. Introduction A good business that is involved in social responsibility and ethical business practices knows how to achieve a winning business of the new century. The practices of these businesses not only work towards providing value to the owners but also add value to the society as a whole. These businesses therefore not only condemn the unethical practices, but also aim to adopt those kinds of behaviors that that provides a positive impact on the stakeholders (The European Commission, Employment and Social Affairs Directorate; Clarson). As a consultant I will therefore identify the ethical practices thatthe XYZ Company must possess in order to examine the affects that ethical business and social responsibility have on the organization and its processes.

Policy brief on New York State - Research Paper Example Comparing the sin tax levy imposed on our state is significantly similar as the one levied on other states. 2. A sales tax is a tax levied on the sale or lease of goods and services and it is imposed at retail level only. Food tax on the other hand can be defined as the tax imposed on the use of food and its ingredients which are meant for human consumption. Similarly soda tax is a tax levied on soft drinks. There is a significant relationship between these taxes as all of them are aimed at reducing obesity which is in the rise in the state and also the medical cost that come with obesity. Therefore, as a way of curbing obesity and other health related problems these taxes are imposed. 3. Considering the adverse effects of alcohol and cigarette smoking in my New York over a period of time, the number of people who are indulging in these risky activities, which affects their health, have been increasing day by day. Comparing it to other states and also the nation it is posing to be a challenge because the number of people engaging in such activities is increasing among the youths. 4. There is a weak negative correlation of -0.061 between the overall tax and the outcomes at the state level implying that as the tax levied is increased the response towards the use of those products reduces. Similarly the correlation of taxes at different regions indicate a positive correlation implying that both the taxes imposed and the outcomes move in the same direction 5. The demand for tobacco, soda and beer are not affected by either an increase or decrease in the price and therefore this implies that people will continue to indulge in consuming these products even after imposing a ‘sin’ tax. This will affect my recommendation since we need to find a way of curbing their use as they are a health threat. My recommendation is mainly based on the budgetary and public health impact

Most Common Form Of Sexual Activity Essay Example for Free

Most Common Form Of Sexual Activity Essay Introduction As depicted in Salvador Dalis The Great Masturbator, masturbation is a fascinating and complex topic that affects each of us differently. Despite almost universal agreement by medical doctors that masturbation is a normal, safe, and common practice, masturbation continues to be associated with embarrassment, shame, and guilt, primarily due to societal perceptions of the act. Yet masturbation is a common and natural function that is practiced by individuals of all sexual orientations, genders, and ages. Masturbation is defined as sexual self-pleasuring that involves self-stimulation. According to recent studies, 97% of men and 83% of women have masturbated at some point in their lives. That is an increase from the 1950s Kinsey Report, which reported that 92% of men and 58% of women have masturbated. Although masturbation is statistically quite prevalent, it is still viewed by society as a taboo subject. Historical Background While there are no direct references to masturbation in cave paintings or other prehistoric artifacts, the practice of masturbation by Bonobo chimpanzees, which share 98.4% percent of our DNA, provides some confirmation that masturbation has likely been practiced since the dawn of mankind. The Ancient World In the ancient world, depictions of male masturbation are relatively common. The Egyptians, for example, celebrated masturbation as the process by which the sun god, Atum, created the first Adam and Eve equivalents, Shu and Tefnut. With the hand of God, Atum masturbated and brought forth the first pair of souls. The Sumerians, who invented the first written Western language, make reference to the Mesopotamian god Enki masturbating, his ejaculation filling the Tigris River with flowing water. Condemnation of masturbation is as old as fertility-worship and is probably based on early man’s realization that there is safety in numbers. A bigger tribe is more likely to gain new territory and expand its power base. In theory, this is this reason that any form of sexual pleasure unlikely to result in a population increase (e.g. masturbation, homosexuality, oral/anal sex) has routinely been denounced as wrong. While in today’s overpopulated world this rationale no longer makes logical sense, this belief structure continues to drive the moral attitudes of many people. In the Judeo-Christian tradition prevalent throughout Western society, the main Scripture quoted by Christians to denounce masturbation is Genesis 38. In biblical times, under Jewish law, a brother was required to procreate with his brothers widow. Onan of Judah refused, and spilled his seed (i.e. ejaculate), on the ground instead. This is the origin of the term Onanism (The Sin of Onan) which is incorrectly used in place of masturbation — in fact, what really happened was premature withdrawal (i.e. coitus interruptus). 18th 19th Centuries It was primarily during the 1700s and 1800s when masturbation was first associated with mental and physical deficiencies. Some prominent physicians, scientists, philosophers, and religious leaders believed that illnesses such as insanity, vision and hearing problems, epilepsy, mental retardation, and general health problems were caused by self-stimulation. In fact, over 60% of medical and mental illnesses were blamed on masturbation. The fear of masturbation was so great that throughout the world, extreme preventative measures were instituted including the use of mechanical restraints, genital surgery, and physical discipline. By the 19th century the cereal magnate John Harvey Kellogg declared sex for anything but reproduction to be sexual excess. Kellogg and others began advocating routine circumcision of males as a deterrent to masturbation. 20th Century In the 20th Century, individuals within the medical community began questioning whether or not masturbation was independent from the various psychiatric and medical illnesses to which it was historically linked. During the 1950s and 1960s, with greater discussion of sex and sexuality and lessening conservative social attitudes along with greater medical research on the topic of masturbation, the thought that the act of self-stimulation is associated with medical and mental illnesses dissipated. Beginning with the Kinsey Report of 1948, masturbation was demystified and even discovered to be beneficial. In 1966, Masters Johnson (see photo) revealed the practice to be virtually universal in North America, cutting across all boundaries of sex, age, race, and social class. In 1971 Goldstein, Haeberle McBride determined masturbation to be the most common form of sexual activity among humans. Today It is clear that masturbation has had a dynamic and varied history. It now almost universally accepted by the medical community that masturbation is a common, safe, and normal practice which occurs in infants, teenagers, and adults. Despite this new attitude, the actual practice and discussion of masturbation continues to be a social taboo within most societies. Former Surgeon General Jocelyn Elder was immediately dismissed by President Clinton in 1994 after she stated that masturbation â€Å"is something that is part of human sexuality and its part of something that perhaps should be taught.† Facts and Figures 1. Masturbation is not evil, dirty or harmful it will not make you go blind, drive you insane, turn you in to a pervert, stunt your growth, give you an STD, make you sterile or get you pregnant. 2. Both guys and girls masturbate, it is a normal and healthy part of sexual development. 3. Masturbation is a very personal thing and should not be done in public places or around people who are not willing partners (think safer sex activity). 4. You are normal if you masturbate, normal if you wonder about it but dont do it, and normal if you never give it a second thought and dont do it it is one of the few things in life that is normal if you do and normal if you dont. 5. Masturbation may make sexual intercourse more enjoyable because you will already know what it takes to please you. 6. Masturbation alleviates stress and releases endorphens (the pleasure hormones) in to your system making you more relaxed. 7. Masturbation as exploration of the body is common in children between the ages of 3 and 6, in teens masturbation becomes more sophisticated and sexually motivated. 8. Surveys have shown that 80% of males and 59% of females have masturbated by age 18. 9. Many experts believe that masturbation is more prevalent in the teen years due to a strong fluctuation of hormones; masturbation alleviates the strain of this build up and is a necessary part of development. 10. The only real problems that come with masturbation are psychological and are the result of unhealthy or weary attitudes toward doing it (if you do it but are ashamed) or abnormal practices (for example, public masturbation). Biblical View. One of the most prevalent rationalizations that people use is that the Bible never mentions masturbation and that it must therefore be alright. Is that logical? Is child molestation alright then? Its not specifically forbidden in the Bible. How about shooting heroin? Or how about torturing someone? Not mentioned! You see how illogical the argument quickly becomes. The most obvious biblical principle that is applicable to masturbation is found in Mt 5:28 where Jesus indicates that lusting after someone in the heart is the same as actually doing it. I am violating whomever I am picturing in my mind during the act of masturbation. It really doesnt matter whether it is a picture from a magazine, (Those are real people!), or someone Ive met or a memory of some act committed in the past. And if I can discipline my mind to think of no one, what of that? Attainment of such focus only serves to make obvious the desperation and obsession that drives us to such lengths. The principles found in 1 Cor 6:12; and Rom 6:14 clearly emerge as foundational to our plight that we are slaves to whatever masters us. When we get truly honest about the habit of masturbation, it is clear that it is a behavior that controls us one that we use to medicate pain, to alleviate stress or to forget rejection. In that way, it is similar to a drug habit just one more vehicle to avoid turning to God. Why wont we turn to God? We may be ashamed. We may believe that Hes going to judge and punish us. We may not trust Him. Or, it simply may never occur to us. We dont normally see God as being involved in the fulfillment of our sexual lives. Hes a Spirit after all and we are physical creatures. And yet, He is in fact the answer to every problem. He can quench our unholy desire and He can teach us to respond to problems by working through them rather than from running from them. Masturbating cultivates yearnings for sensations that differ from those generated by intercourse. Ju st how destructive to heterosexual relations this becomes will vary from person to person. Even in the mildest case, however, it would seem inevitable that masturbating when single will detract from one’s future enjoyment of, and appreciation of, the uniqueness of heterosexual relations. It is not uncommon for people to find themselves so addicted to solitary sex that they actually prefer it to heterosexual relations and it is even more common for people feel they at least occasionally need the unique sensations that solitary sex offers, despite having an eager sex partner readily available. Nevertheless, suppose your marriage partner somehow manages to fluke giving you sensations so like what masturbation has trained you to crave and expect that you do not actually find yourself preferring solo sex. Even then, your mind has been trained to connect those feelings not with intimacy with your marriage partner but with having sex with yourself. Want it or not, masturbation programs your mind to think of sexual feelings not as a precious gift from your partner, but as something you have generated yourself. So what will come flooding into your mind when your partner lovingly gives you those feelings will tend to be not thoughts of how wonderful your partner is, but of how much pleasure you used to give yourself. Despite what is actually happening, your mind will tend to register the sensations not as coming from your life partner but as if they were produced by yourself. Feelings that should be binding you to your marriage partner have already been locked in your mind as being associated with having sex with yourself. When making love, your mind will consciously and unconsciously flit from what is currently happening between you and your partner to what used to happen when you had solitary sex. For example, if your past history of masturbation had trained your mind to associate sexual feelings with fantasizing about an imaginary partner, that is what your mind will drift to, even though you now have a real partner who does not correspond exactly to your imaginary partner. Even if your partner somehow manages to exceed the heights of what you used to experience in solitary sex, masturbation will have cheapened the most precious sensual gift your partner could ever give you, to being something only ten or so percent more pleasurable than what you used to give yourself. Past masturbation will have robbed you of so much of the â€Å"magic† and bonding power of marital relations, thus weakening your marriage. Church View Roman Catholic The Catholic Church teaches that Masturbation constitutes a grave moral disorder and that both the Magisterium of the Church—in the course of a constant tradition—and the moral sense of the faithful have declared without hesitation that masturbation is an intrinsically and seriously disordered act. Although it is said that psychology and sociology show that masturbation is a normal phenomenon of sexual development, especially among the young, this does not change the fact that it is an intrinsically and seriously disordered act and that, whatever the motive for acting this way, the deliberate use of the sexual faculty outside normal conjugal relations essentially contradicts the finality of the faculty. For it lacks the sexual relationship called for by the moral order, namely the relationship which realizes the full sense of mutual self-giving and human procreation in the context of true love.' This is because the deliberate use of the sexual faculty outside of marriag e is, according to the teaching of the Church, contrary to its primary purpose of procreation and unification of the husband and wife within the sacrament of marriage. In addition, the Church teaches that all other sexual activity—including masturbation, homosexual acts, acts of sodomy, all sex outside of or before marriage, and the use of any form of contraception or birth control—is gravely disordered, as it frustrates the natural order, purpose, and ends of sexuality. To form an equitable judgment about the subjects moral responsibility and to guide pastoral action, one must take into account the affective immaturity, force of acquired habit, conditions of anxiety or other psychological or social factors that lessen, if not even reduce to a minimum, moral culpability. The traditional view of masturbation has been consistent for almost all of the Catholic Churchs 2,000-year history. Early Catholic theologians universally condemned both masturbation and contraception as sinful. One such example is Clement of Alexandria, considered a saint and a Church Father, who said of masturbation, Because of its divine institution for the propagation of man, the seed is not to be vainly ejaculated, nor is it to be damaged, nor is it to be wasted.. St. Thomas Aquinas, one of the most prominent Doctors of the Roman Catholic Church, wrote in the 13th century that masturbation was an unnatural vice which is a species of lust as bad as bestiality, sodomy, and pederasty, and that it by procuring pollution , without any copulation, for the sake of venereal pleasure pertains to the sin of uncleanness which some call effeminacy However, after a study commissioned by the Catholic Theological Society of America in 1972, a number of dissident Catholic theologians have come to hold that an act of masturbation should not be judged as an objective moral evil, but assessed within the life context of the person involved. Protestant Theologians toward the middle of the 20th century began revising previous teachings, and some today even take pro-masturbation viewpoints. Some view it as an act of self-indulgence and even a sin of the flesh, and believe that the practice is principally considered a sin because of its invitation to lust. Those who view it within the range of allowable sexual behavior encourage it as guard against adultery, pre-marital sex, or other forms of non-allowable sexual behavior, and as a method of balancing differing libidos between spouses. Arguments Masturbation decreases rather than increases vice. Objection 1: Masturbation is a squandering of human time and physical energy that could otherwise be used for Godly worship, self-improvement, or good works. Objection 2: Masturbation inflames carnal lusts, leading to worse sexual vices. Objection 3: As an indulgence of physical appetite, masturbation encourages indulgence of other appetites, such as gluttony. Reply to Objection 1: It is said that idle hands are the devils workshop. Insofar as masturbation occupies the onanist, it prevents him from engaging in vicious or destructive acts. Reply to Objection 2: Rather than inflaming carnal lust, masturbation dissipates it by a harmless release of sexual tensions. In doing so, it removes, rather than proliferates, the driving force that motivates acts of sexual vice. Reply to Objection 3: Pent up libido will seek relief through other channels, and without the relief of masturbation, might well find its expression through the satiation of other appetites such as gluttony, gambling, and other material vices. Masturbation is a salutary use of the reproductive organs and does not conflict with reproductive sex. Objection 1: Masturbation enervates the sexual organs. Objection 2: In the male, masturbation wastes sperm that would otherwise be used for conception. Objection 3: By providing an alternative release of sexual energies, masturbation cheapens and may even diminish the physical gratification to be found in reproductive intercourse. Reply to Objection 1: Masturbation exercises the sexual organs and assures that they are in good working order. It prevents stagnation of fluids and atrophy of tissues, and in the male, increases the quality of sperm by stimulating the production of fresh gametes. Reply to Objection 2: Science has shown that regular and frequent ejaculations increase the quality of a males sperm by stimulating the production of fresh and healthy gametes. Therefore men who masturbate regularly are more likely to father a child. Thusly, the spilt semen is but a sacrifice toward a more favorable chance of achieving conception. Reply to Objection 3: Especially in the case of women, by demonstrating the range of possible sexual pleasure that one is capable of experiencing, masturbation encourages one to enter into a sexual relationship with confidence in ones own sexuality, and with the expectation of a positive experience. Masturbation makes a positive contribution to human society. Objection 1: Masturbation is most often a solitary, private and antisocial act, and is therefore contrary to human interaction and community. Objection 2: As a act of self-gratification and self-indulgence, masturbation encourages selfishness and promotes the tendency to put ones own needs first above others. Objection 3: As a form of self-love, masturbation engenders narcissism, pride, and self-regard, which are detrimental to forming human relationships. Reply to Objection 1: Masturbation is an activity in which all sexually mature humans may engage, therefore it can serve as a commonality upon which to build understanding amongst those of differing nationalities, viewpoints, etc. Reply to Objection 2: After engaging in masturbation, an individual will be in a relaxed, fulfilled, and pleasant mood, and therefore more apt to extend charity and good will toward others. Reply to Objection 3: The act of masturbation can give a sense of mastery, self-confidence, and ownership of ones body. Healthy self-esteem and a clear sense of self are necessary for healthy emotional bonds.

Blood Oxygenation Level Dependent FMRI Psychology Essay

Blood Oxygenation Level Dependent FMRI Psychology Essay Functional magnetic resonance (fMRI) is the most widely used and powerful method of understanding the brain function and mapping neuroanatomy of the human brain. The most basic fMRI technique is blood oxygen level dependent (BLOD-fMRI). Paramagnetic deoxyhemoglobin in venous blood is a natural contrast agent for magnetic resonance imaging (MRI). Basic principles and methodological applications of BOLD-MRI as an introduction are presented in this article, and the relationship between neural activation and a magnetic resonance signal change is represented in much detail. Introduction Functional magnetic resonance (fMRI) is a widely recognized technique for brain mapping and providing the anatomical information of brain activity. It has been demonstrated that this method bases on the local hemodynamic changes that influence deoxyhemoglobin changes in venous blood. Furthermore, susceptibility changes produced by deoxyhemoglobin changes lead to the changes of MR signal strength. This effect is called blood oxygenation level dependent (BOLD) contract (1). High spatial and temporal resolution brain mapping can be structured by this basic method. Currently, it has become the most powerful study of brain function techniques. Compared with the traditional neuroimaging methods, including positron emission tomography (PET) and intrinsic signal optical reflection imaging, BOLD-fMRI can provide high spatial and temporal resolution sufficiently using internal concentration of oxygenation in human bodies as a natural contrast agent. Blood oxygen level dependent (BOLD) effect was firstly presented by Ogawa etc in 1990. They found that the magnetic resonance signal reduces when the concentration of oxyhemoglobin decreases. Also, their research showed that the reduction of signal not only occurs in blood, but also outside the blood vessels. Thus, they assert that this effect is caused by the property of magnetic field changes. After that, many researchers performed a large number of theoretical and experimental works to summarize the basis of BOLD-fMRI imaging. When neuron is activated, regional cerebral blood flow and oxygen consumption volume increase, but there are differences between the two increases, which is that the increase in cerebral blood flow is more than the oxygen consumption. Due to this difference, the venous oxygen concentration in active regions is significantly higher than the surrounding tissue and the concentration of deoxyhemoglobin reduces relatively. BOLD contrast has its origin in the fact that when normally diamagnetic oxyhemoglobin gives up its oxygen, the resulting deoxyhemoglobin is paramagnetic (2). Deoxyhemoglobin is a paramagnetic material which can produce local gradient magnetic field in the blood vessels and surroundings. Hence, it has effect on reducing T2. When brain areas are activated, the effect of reducing T2 decreases result from the reduction of deoxyhemoglobin. Compared with the resting state, T2 or T2* is relatively extended in local brain regions. Therefore, the signal is relatively enhanced on the T2 weighting or T2* weighting functional magnetic resonance imaging maps. Current MRI brain mapping studies all focus on off-on subtraction mode, which is the fMRI signal in active condition minus the signal under control conditions. The signal is extremely weak, and the relative increasing strength is 2%-5% generally. During imaging, the functional image of corresponding brain areas can be obtained if superimposing the high signal in different colors of active area on the high-resolution T1 weighting anatomical maps. This method is called blood oxygen level dependent contrast fMRI due to it depends on the level of oxygen in local blood vessels (1). This article reviews the basic principles and available methodological information and research on blood oxygen level dependent (BLOD-fMRI). This review begins with some basic principles on BOLD-fMRI. Furthermore, the methods for BOLD-fMRI will be described in detail including block design and event-related design. Also, the results of BOLD-fMRI studies will be presented and the advantages and limitations of the current research will be discussed as well. Finally, the key points and important aspects of the BOLD-fMRI will be summarized as a conclusion. Materials and Methods BOLD-fMRI experiment steps include: firstly, make experimental planning and determine the most optimal stimulus or task programs. Secondly, high T1 WL resolution anatomical images and a great number of original images in stimulation and rest states can be obtained by scanning. Lastly, functional active maps should be obtained by experimental data analysis. Block design bases on cognitive subtraction mode to show the stimulus task in block form. A tropical block design contains two basic tasks which are experimental tasks and control tasks, and the two intervals of blocks appear. Task-related brain activities can be understudied by the comparison of regional cerebral blood oxygen reaction through stimulation and control tasks. It is widely used in locating brain function. It is the early main method to do functional magnetic resonance imaging experiments. The advantages are simple and easy to perform tasks. However, the drawback is that the BOLD signal changes larger result in long stimulation time and the high rate of oxygen reaction. In blocked designs, regardless of stimulus presentation or task performance interdigitated with rest, observing the relationship of the time course of BOLD response to activation paradigm is possible (3). Also, more than one image can be obtained during every experimental and rest period. The signal time course should be assumed to be activated, and it can be tested. A simple example is presented in Figure 1(a). Firstly, switch on and off the visual stimulation (black and green) quickly for 10 times. It is shown that the time course of pixels follows the stimulation paradigm. However, the difference between the stimulation and time course is quite obviously (p
