Hate groups in US Essay Example | Topics and Well Written Essays - 500 words

Hate groups in US - Essay Example Their primary purpose is to spread malice and enmity and create a source of fear within the society. Hate groups are known to be more prevalent in the United States of America (USA) with a constant rise in the numbers and as per the Southern Poverty Law Centre ( SPLC) , 2011 has shown over 1000 active hate groups (Roy, 2002). The Anti-Defamation League (ADL) and the SPLC are the two main organizations in the USA that monitor hate groups and help maintain law and order. (Roy, 2002) Various reasons and explanations have been put forward by researchers as to why such hate groups exist, the main factors being: economical crisis, antipathy towards the immigrating crowd, political turmoil, change of governments and minor groups not been given equal opportunities. Reasons can be plenty but none justify their existence and the fact that the US government is unable to eradicate such groups. SPLC maintains a list of these groups and supports the Federal Bureau of Investigation (FBI) in their f ight against these radical groups. The hate groups demonstrate their views through speeches, meetings, rallies and criminal acts of violence as well to prove their point (Roy, 2002).

Fundamentals of Healthy Lifestyle Essay Example | Topics and Well Written Essays - 2500 words

Fundamentals of Healthy Lifestyle - Essay Example Center for Disease Control recommends people to engage in physical activities to combat diabetes (Samuels 1). I experienced many health problems while consuming unhealthy food that is why I turned to healthier choices. By healthy lifestyle, I mean cooking and preparing my meals and snacks using organic products. The outcome so far to this lifestyle change has been a change that I'm more than happy I did. My healthy lifestyle routine consists of my personal health, saving money while eating clean, and being physically active and productive in my daily activities. As an individual, you have the responsibility to take care of your health through eating lifestyles changes and participating in physical activities. Considering my personal health, I come from a family who has been diagnosed with diabetes type one. According to the National Diabetes Statistics Report, that was released in 2014 "1.25 million American children and adults have type 1 diabetes" (Statistics About Diabetes 3). The type one diabetes is genetically passed, and it is a disease that cannot be prevented and you cannot get rid of it. It also occurs when the immune system attacks the insulin-producing cells in the pancreas. Symptoms to the type one diabetes usually start during childhood or young adulthood. Episodes of low blood sugar levels also known as hypoglycemia are common. Diabetics struggle a lot with emotions. They often lash out for little things because they experience the emotional roller coaster. They have to visit frequently the doctor, they need support from their loved ones, they need encouragement, and sometimes they feel lonely because they feel their disease is controlling them rather than them controlling the disease. These statistics are scary enough, which made me consider a healthier way of life. I wanted to be around my friends and family for a long time.

Diffusion weighted (DW) Magnetic Resonance Imaging MRI Essay

Diffusion weighted (DW) Magnetic Resonance Imaging MRI - Essay Example The exploration of diffusion in MRI includes the way MRI is sensitized to diffusion; the effects of spins, both stationary and moving spins; how diffusion-weighted images are affected by physiological motion; the how of the achievement of the various diffusion weightings; and information on diffusion and how those are measured (Hagmann et al. 2006; Mori and Barker 1999, pp. 102-106; Tonarelli 2012; Parker 2004, pp. S176-S178; Everdingen et al. 1998; Barker 1999; Maas 2005; Le Bihan et al. 2006; Yablonskiy et al. 2003; Koh and Collins 2007; Le Bihan 2011; Basser and Jones 2002; Battal et al. 2012; De Foer 2010; Luypaert et al. 2001; Williams et al. 1992; Topgaard 2006) II. Background on Diffusion Diffusion on the molecular level is said to be the result of natural Brownian movement, where molecules randomly move through the diffusion medium because of the agitation caused by thermal characteristics of the medium. In all the displacement of the molecules comes up to zero by mean figure s, but over time, there are positive probabilities associated with the non-zero movement of a molecule, so that over time, a molecule is said to probably have moved from an initial position at an earlier time. Here the time elapsed corresponds to a correlation with the distance moved, where different fluids acting as diffusion mediums determine the distance as characterized by the diffusion constant for that liquid type. There is a difference between the freely diffusing movement of water molecules, meanwhile, to the diffusion of liquids in the tissues of human beings, so that in human tissues one talks of an ADC, or an apparent diffusion coefficient, to be differentiated from the free diffusion coefficients of liquids outside of human bodies, such as those used to characterize water in containers at certain temperatures. On the other hand, for human tissues, various considerations further come into play, such as differences in the mobility of different fluids in different parts of the body and in different parts of a particular organ, such as the human brain. Boundary conditions also differ for liquids found in different body parts. All these affect the coefficient of diffusion in various ways, with the general observation that the ADC is generally smaller in comparison to the free diffusion coefficients of liquids like water outside of the human body (Luypaert et al. 2001; Roberts and Rowley 2003). Going into diffusion types, meanwhile, there are two, one being isotropic diffusion and the other being anisotropic diffusion. In isotropic diffusion, the rate of diffusion is the same in all directions, and so the resulting diffusion distribution is spherical. In anisotropic diffusion, the diffusion rate depends on where the diffusion is oriented, and there is uneven diffusion in different directions. The distance of the diffusion is orientation-dependent, in other words, and the diffusion distribution is characterized by an ellipsoid (Module 1 2013). III. MRI an d Diffusion A. How MRI is Sensitized to Diffusion In a hypothetical case, the typical distribution of displacement of water molecules in such a container is said to follow a bell curve, with majority of the water molecules able to travel only for short distances from their initial location, whereas a few of the water molecules are able to be displaced at further distances from average. For a given initial temperature of the water, moreover,

How does the US Constitution relate to the US Army Officer Corps Essay

How does the US Constitution relate to the US Army Officer Corps - Essay Example The US Constitution is the supreme law of the country, providing framework for organizing its government.Other than defining the organization of these arms, the constitution clearly outlines the powers exercisable by each branch of government. The Constitution also reserves some rights for each individual state and therefore establishes the US federal system of government.It defines three the three major government arms namely the executive under the leadership of the President, the judiciary headed by the Supreme Court and the legislature consisting of a bicameral Congress. The US Constitution was enacted in 1787 through a convention in Philadelphia, Pennsylvania, but later underwent ratifications in every state, and further underwent amendment twenty times.The US Army is a military, whose primary misson is providing the required forces and capabilities to boost national security and defense strategies. The Army is the largest and oldest branch of the armed forces and among the seve n uniformed operations. The modern Army traces its roots back to the Continental Army formed in 1775 to help in meeting the demands of the American Revolutionary War, before the United States was established. Most US Army units can be divided into various components including the following units: the Corps, Division, and Brigade, regiment, Battalion, Company, Platoon, Squad, Section, squad and team. The Corps is a large administrative and administrative grouping of troops within the armed forces having a common function like Artillery or Signals. The relationship Various views with regard to the source of war power were expressed in the early years of the US constitution making and continue to seek supremacy even now. A theory was to the effect that war power comprises the particular powers granted by Article 1, Section 8. Later in 1795, the theory's argument was advanced further that the National government's war power is attributed to sovereignty and hence independent of the confirmatory grants of the written constitution. Later, Chief Justice Marshall took a different view that the authority to wage war is implied from that to declare it (Kohn et al, 1988). According to the US Constitution, the President is the Commander-in-chief of the military although Congress is the one empowered to declare war by Article One, Section Eight, and not the President. However, Congress has always authorized Presidents to deploy troops in the event that a war has not been declared explicitly. Since the Second World War, major military actions have mainly been US military operations or UN police actions that are considered justifiable legally due to decisions like Authorisation for Use of Force, the Gulf of Tonkin Resolution and numerous other UN Resolutions. This was also the case for the Korean War that was only considered a war by an Act of Congress. The The US Constitution does not apply to the military personnel exactly the same way it does to civilians. Even though the military is not excluded from the rights contained in the Bill of rights of the constitution, Article One, Section Eight grants Congress authority to make government rules as well as regulate the land and naval forces. Practically, most of the constitutional rights of the civilians are also accorded to the military, even though some differences are introduced to suit the situation in the military. With regard to right of warning and right of counsel the military has broader protection than those in the constitution. Military appellate courts are used for interpreting military law and ensure it is consistent with the constitution as much as possible (Kohn et al, 1988). The Second Amendment of the US Constitution created a well regulated militia in order to boost security of the Free State as well as the right for people to bear and keep arms. This amendment was enacted in an environment pervaded by emerging republican ideology as well as with the help of various suggestions from

Law Essay Example | Topics and Well Written Essays - 500 words - 5

Law - Essay Example They are also liable for replacement of the faulty blu-ray player purchased by Bob from them although more than 3 days have passed after the purchase. Reckless Department Store is just what their name expounds – it is reckless. One cannot do business in a reckless manner. The removal of the lower guard rails on the stairwell despite many complaints from customers was responsible for Lassie’s death. The fracturing of Bob’s skull due to the barrier’s crash on the car’s roof was also the fault of Reckless Department Store because the car park was handled or mishandled by them. Finally, the malfunction of the blu-ray player must be set right by Reckless Department Store because they cannot count the number of days Bob spent in the hospital for the purpose of the sale contract (Unfair Contract Terms Act 1977, p1). Actually, Erewhon Police Service must take the initiative in handling all the three cases. This is because of Reckless Department Store’s negligence that the mishaps have occurred. Reckless’ irresponsible behavior resulted in the loss of their dog, and loss of manpower as Bob could not report for duty during his time at the hospital. The three cases must be handed to a legal expert who will be able to interpret the laws to their logical conclusions. Reckless Department Store is misinterpreting laws to its own benefits. First of all, Reckless must have closed operation or relocated elsewhere while renovation work was going on. By not keeping business closed due to renovation, Reckless was exposing customers to myriad risks and dangers. Reckless must be taken to task sufficiently so that it sends the clear message for Department Store and other businesses to close operation or relocate while renovation is in progress in their own premises. Otherwise it will become easy for others to carry on business in similar circumstances and throw up their hands when faced with litigations for accidents and losses

National Foundation for Educational Research Essay Example for Free

National Foundation for Educational Research Essay Over the last century different techniques have been used to organise children within schools according to what the public and government asked for and needed. For example after the Second World War the number and size of schools increased, the tripartite system of secondary education was introduced and there was increased competition for grammar school places Sukhnandan and Lee (1998 pg. 13). There was a drive for excellence and the 11 plus exam leant itself easily to the administration of streaming. However during the 1960s research was carried out that suggested streaming had negative social consequences for pupils, which could have been the catalyst for the shift of emphasis from excellence to equality. This resulted in a shift from streaming to mixed ability teaching that continued throughout the 1970s and 1980s. Ability grouping, in the form of setting and within class grouping, was sometimes used in higher year groups for linear subjects such as maths, science and modern languages but mixed ability was the main grouping method. The essay question implies that again there has been a shift, this time to setting. Boaler et al (1998) seems to imply that pressures from the government are to blame for this move; suggesting research (Gewirtz, Ball Bowe, 1993 cited in Boaler et al 1998) indicates some teachers regard the curriculum set out in the 1988 Education Reform Act as incompatible with mixed ability teaching implying that they have no choice. Todays Governments seem to be increasingly interested in achieving goals and raising standards, even if this means children missing out on the social advantages of mixed ability grouping. Setting seems to reinforce social divisions, as there are a higher proportion of boys, children of lower socio-economic status, children born in the summer and those of ethnic minority backgrounds in the lower sets (Boaler, 1997a, 1997b. Oakes, 1982. Sutton, 1966. Cited in Sukhnandan and Lee, 1998. ) whereas children in mixed ability classes tend to come from a range of different backgrounds. I find this quite extraordinary, as the Scottish Parliament has recently spent millions on an anti-racism campaign. Surely segregating the children, albeit unintentionally, will undermine the message sent out by this campaign? The essay will discuss the advantages and disadvantages research has told us concerning setting. It will begin with the discussion of the effect of teachers attitudes and expectations of the set that they are teaching. It will then discuss the limitations pupils face by being placed in sets. It will discuss the social gap created by teaching children in sets. It will also discuss the advantages to the teacher of teaching children in sets and the advantages to the pupils. The essay compares setting to mixed ability teaching on several occasions this is because mixed ability teaching was the technique used before the recommendation to use setting also there seems to only be limited research on the other forms of grouping. Research has shown there to be both advantages and disadvantages to setting. Boaler et al (1998) demonstrated many disadvantages to setting. In their paper they cited a worrying statistic Jackson (1963) 96% of teachers taught to streamed ability groups meaning they taught all the children without consideration into their individual differences. Boaler et al (1998) made reference to some of the experiences of pupils in setted mathematics classes, they reported that their teachers consistently made comments such as youre in the top set, you should be able to do this and youre in the bottom group your not going to learn anything. These attitudes are undoubtedly detrimental for the child. Boaler et al (1998) reported that children in higher sets were disadvantaged because their teachers had too high expectations of the children they were teaching, one third of the children taught in the highest sets felt they were being pushed to hard, that their lessons were paced too fast and they were under too much pressure to succeed because of their teachers expectations and the competitive ethos between pupils in higher sets. This was discovered to really upset certain children, Boaler et al, (1998) I mean I get really depressed it really depressed me, the fact that everyone in the class is like really far ahead and I just dont understand. It was reported that girls were the most affected by this citing the fact that although girls have been reported to be overtaking boys in all subjects boys still get the highest grades in mathematics (where the use of setting is dominant). The complete reverse was reported for those in lower sets, who felt that their lessons were too slow; they werent being challenged so lost interest. They believed that their teachers had no faith in them. This would then lead to a self-fulfilling prophecy, they have no option but to perform to the set that they are allocated, if they are not encouraged then they will languish in the bottom sets their entire school life. This causes a self fulfilling prophecy, if they are told that theyre incapable of anything more they will begin to believe it, so they wont try to do anything more. Even if the children in the lower sets worked to be moved up into the higher sets they are unlikely to be successful. Teachers teach the children in specific sets to different tiers of an exam, so those in lower groups will not learn the same things as those in higher groups so movement between the sets would be difficult. The idea that children are taught to specific tiers is generally problematic because children are allocated to sets up to three years before they sit the exam and as mobility is rare this can have detrimental effects on their attainment if they were aware that they could only get a low grade. Boaler et al (1998) reported that only some children actually knew the implications of this. The teachers high expectations of those in higher sets and low expectations of those in lower sets causes a further social gap between the sets, those in the top sets will be called boffins and those in the lower sets will be seen as stupid. This is further intensified by the allocation of better qualified and more experienced teachers to higher sets even though research suggests (Black and Wiliam, 1998, p42 cited in Boaler et al 1998) that this type of high quality teaching is more beneficial to those children in lower sets who need more guidance as they are more easily distracted. The lower ability children will recognise that the higher ability children are seen as better and again this will have detrimental effects on their self-esteem causing them to become interested in anti-educational activities where its cool to be alienated (Hallam article from TES website, Passmore 2002) and will heighten the rift between the ability groups. In a mixed ability class for example there is a reduced distinction between childrens ability, which is beneficial to the children. There is even the suggestion that children of lower ability use those of higher ability as role models. A further problem could be caused because of a distinction made between academic and vocational subjects. Only subjects such as Maths, Science, English and Modern Languages are set while subjects such as Art and Music are mixed ability as a general rule. Children who are good at art and music may not feel as valued as those who are good at maths. The emphasis for teachers seems to be applied to children in higher sets because they get taught by the best teachers and get taught in the best classrooms. Also the children who arent interested may distract other children in these mixed ability groups. Ultimately this will lower their self-esteem and have a negative effect on their attainment in and feelings for the subject. Of cause there must be advantages to setting otherwise the First Minister wouldnt have recommended it. One major advantage is that, compared to mixed ability teaching, its easier for teachers to implement as they can pitch work at a level that is more appropriate for the level the children are at. In mixed ability teaching a large majority of the class are unsupervised while setting lends itself to whole class teaching. This would appear to benefit those children in both higher and lower ability groups. Children in higher ability groups could be neglected and left to get on with their work in mixed ability classes while in sets these children will be given more attention, the children in with less ability will feel less inferior and more confident in groups of children with similar ability. Another benefit for high ability children is that low ability children who dont want to learn will not distract them. The government is aiming to raise standards so its understandable to want to give children of higher ability a better chance. Research (Kulik and Kulik, 1982. 1987. Cited in Sukhnandan and Lee, 1998. ) shows that gifted and high ability children achieve more when placed in sets than they do when placed in mixed ability groups. Its believed by some that high ability pupils benefit in groups with similar ability because it increases motivation by providing appropriate challenges and competition. There is also the implication that the children will be like-minded, facilitating the opportunity for them to discuss and bounce ideas between each other. Possibly the main reason why the First Minister recommended this form of ability grouping is because all the research conducted in this area conflicts resulting in there being no truly consistent findings on the effect of ability grouping for pupil achievement. His recommendation could therefore be based on the fact that setting is easier for teachers so it is more likely children will be taught effectively. His main concern appears to be with raising standards and setting is easier to manage and improve than mixed ability teaching as set guidelines can be given for the attainment targets for each set. The blame for these inconsistent findings has been given to the research methods used. Theres a suggestion made that the outcome of ability grouping isnt the only thing being tested. The quality of teaching, the teachers expectations, the pupils expectations and the materials available will all effect the pupils achievement. The evidence seems to produce more disadvantages to setting than advantages. The main ones being social rather than necessarily academic. However a child will perform better if they are happy and confident. Being labelled as set 6 is not good for a childs self esteem or confidence especially when teachers reinforce the idea that they are not as good as those in higher sets. This ultimately leads to a self-fulfilling prophecy, which eventually causes the child to lose all interest. If the First Ministers objective really is to raise standards then shouldnt he be focussing on these low ability children and trying to raise their attainment levels? High ability groups also suffer because of the expectation that they are more capable than they actually there. To improve this it might be necessary to re-teach teachers on pupil differences and explain that all the children within the set are not identical. For this to occur theyd have to be a reduction in the emphasis placed on meeting targets, teachers need the flexibility to return to areas that children are finding difficult. When all said and done isnt education for the benefit child? The First Ministers recommendation needs to be accompanied by guidelines for teachers on how they can avoid the negative effects of homogeneous grouping. These guidelines should include careful planning, using well-defined targets and remaining aware of the negative effects of ability grouping (GB. Scottish Office. HMI, 1996. Cited in Sukhnandan and Lee, 1998. ) There could also be a move away from emphasis on academic achievement to more recognition of non-academic achievements to restore the self-esteem of children in lower ability groups (Elton Report, 1989. Taylor, 1993. Cited in Sukhnandan and Lee, 1998. ) His recommendation was probably the right one considering the drive to raise standards and make teachers lives easier. Because of the lack of conclusive evidence for what type of grouping is more beneficial academically for the child he was right to choose the method that could be most easily implemented and controlled. However this lack of conclusive evidence means that more research needs to be carried out to discover what the best form of grouping is. To do this researchers will have to establish what is ultimately best for the child, possibly new ways of grouping could be developed or the old ways upgraded.
