Total Synthesis Of Cp Compounds Essays (578 words) - Total Synthesis

Total Synthesis Of Cp Compounds Man's fascination with the many uses that can be found with the exploitation of natural substances has been demonstrated time and again throughout history, but the stage was set at the turn of the century for organic chemists to begin to focus on utilizing natural compounds for the benefit of medicinal and industrial uses. The discoveries of penicillin, aspirin, and other naturally occurring useful compounds in the earlier parts of the century set the stage for the utilization and exploitation of biologically active compounds as a molecular science. However, there are limits as to how much we can do with what nature provides us. This puts the role of the synthetic organic chemist at the forefront of synthetic compound synthesis technology. KC Nicolaou is one such leader. The main goal of Nicolaou's lab is the complete synthesis of naturally occurring compounds, along with solid phase chemistry, molecular design, combinatorial synthesis, and biological investigations; some of the results of Nicolaou's work include: the total synthesis of the anticancer agent Toxol, the marine neurotoxins brevetoxins A and B, the anititumor agents epothilones A and B, eleutherobin and sarcodictyins, the antibiotic vancomycin, the cholesterol-lowering CP-molecules, the immunosuppressant agent sanglifehrin A, the antibiotic everninomicin, and a number of bisorbicillinoids such as trichodimerol, bisorbicillinol, and bisorbibutenolide. Another example of Dr. Nicolaou's work is a paper published in Chemistry International entitled The Absolute Configuration and Asymmetric Total Synthesis of the CP Molecules (co-authored by Jae-Kyu Jung, Won Hyung Yoon, Yun He, Yong-Li Zhong, and Phil Baran.) In this paper, Nicolaou and his associates describe how their goal was both the total synthesis of these CP compounds (achieved in 1999) along with the determination of their absolute configurations; methods used in initial attempts to determine absolute configuration at different carbons included X-ray crystallography and NMR. Nicolaou set about synthesizing this compound by thinking through possible reactions that he might use to begin to build the carbon skeleton needed for this molecule. His team decided on a type-II intramolecular Diels-Alder reaction as the key step to generation of the core skeleton. The Diels-Alder reaction utilizes a dienophile in order to form new carbon-carbon bonds in a single step, in this case to form multiple ring structures. However, Nicolaou ran into trouble when several reagent-based enantioselective approaches with the precursor failed to yield appreciable levels of the desired product. After much study of this problem, Nicolaou's team came to the conclusion that a Lewis acid catalyst would be their best shot at inducing the asymmetry needed for this particular absolute configuration. After several more reaction steps, the team had two diastereomeric diols in a racemic mixture that were then converted to enantiomeric aldehydes with TBAF and NaIO4 - induced oxidative cleavage. After conversion to the indoline, the synthetic compound was compared to the naturally derived compound using NMR, TLC, and IR spectroscopy. However, the optical rotation of the synthetic compound was opposite in magnitude to the naturally derived CP molecule; the synthetic compound was verified as the enantiomer of the naturally occurring compound circular dichroism spectroscopy, and thus, the absolute configuration was verified. This paper parallels Nicolaou's research goals by showing how this team determined the absolute configuration of a complex compound they synthesized from a much simpler molecule (glycidol). It also shows the importance of techniques used to determine structure and content of complex molecules, such as NMR and IR spectroscopy. Science

Communist Manefesto essays

Communist Manefesto essays The Mid-Nineteenth century in Europe was a melting pot of activity. The industrial revolution was in full swing in Great Britain, while the Prussian empire slowly grew in size. Over most of the continent the people were poverty stricken while few thrived in the economy. Rebellions of the middle classes were common in this era. Liberal philosophies were showing up in a few different political radicals. Due to this liberal thinking political philosophers such as Karl Marx and Friedrich Engles had the ability to express their opinions over a broad variety of people and this is the time in which the Communist Manifesto came to be. Karl Heinrich Marx was born on May 5th, 1818 in the city of Trier, Germany to a comfortable middle-class, Jewish family. His father, a lawyer and ardent supporter of Enlightenment liberalism, converted to Lutheranism when Marx was only a boy in order to save the family from the discrimination that Prussian Jews endured at the time. Marx enjoyed a broad, secular education under his father, and found an intellectual mentor in Freiherr Ludwig von Westphalen, a Prussian nobleman with whom Marx discussed the great literary and philosophical figures of his day. Notably, it was Westphalen who introduced the young Marx to the ideas of the early French socialist Saint-Simon. As a student in Bonn and Berlin, Marx was greatly influenced by the philosophy of Hegel. While Marx was impressed with the Hegelian professors under whom he studied, he ultimately found himself attracted to a group of students known as the "Young Hegelians." This group of young iconoclasts, including David Strauss, Bruno Bauer, and Max Stirner, were inspired by Hegel but were determined to champion the more radical aspects of the old master's system. In particular, these Left Hegelians called into question the conservatism they saw in Hegel's avowed political and religious philosophies. Although Marx desired a career as an academic at the time, ...

Compare and contrast social policies in one or more post communist Essay

Compare and contrast social policies in one or more post communist societies and any South East Asian or Latin American country - Essay Example Whereas the post-communist state, Ukraine still has soviet features in its policies although they have improvised a lot since their independence. Significant alterations in their social security strategies have taken place however; some changes have aided even less to the protection of the nation than before. The social insurance system of Brazil composes of schemes regarding the welfare of people in old age, people with disabilities, survivors, unemployed individuals, relying families of insured but apprehended people along with maternity coverage for women. Their social safety plans guarantees the protection of people in times of vulnerability or for their welfare during a crisis. They provide pensions for the retired and the incapacitated that has inadequate means. Such plans are included in schemes like the Bolsa Famà ­lia Programme (Dear 2001). On the other hand, the social security system of Ukraine comprises of the same constituents with different perspectives. Regarding the insurance policies for old people their strategy has moved from being mandatory state pension insurance to Non-State Pension Provision both in 2004. The former being based on taxes from the employees and the latter being based on the voluntary contributions from the nation to provide tax relief. The changes in reforms for the unemployed altered from being financed by the employers solely to being aided by the employees too. Regarding their policies during crisis situations their history is not as impressive as the country had to face famine, the after effects of World War II and significant migrations that followed their independence. (Dear, 2001) The figurative data of both countries regarding public social security expenditure (including health) as % of PIB is 21.0 in Brazil while it is 17.0 in Ukraine and the public social security expenditure (including health) as % of government expenditure is 16.0 in Brazil whereas it is 13.0 in Ukraine (Kakwani

Why Sex Education Should Be Taught In Schools Essay

Why Sex Education Should Be Taught In Schools - Essay Example The research will be that of a case study analyzing, in detailed and succinct manner, teenage pregnancies as the most effective factor in sex education. Recent research reveals that there have been high increases in the cases of teenage pregnancies. Studies conducted over the last five years state that for every 100 school going/teenage girls, two of them are dropouts due to pregnancies. The statistics or findings have been backed up by the increased abortion cases in the state. The major cause of abortion has been discovered to be teenage pregnancies. This discussion stresses that several questionnaires were distributed to several respondents in Chicago with an aim of investigating the people’s reactions, views, or attitudes towards sex education in schools. The questionnaires were distributed in three different areas; Oak Park, Cicero, and Illinois. Six hundred questionnaires were distributed in each location. The questionnaires were of two types, the different being the ages of correspondents. The first types targeted the old age, most of whom were married people with their kids at school. These questionnaires constituted to a third of the total number of questionnaires distributed in each region. The remaining two thirds were distributed to school going students, both in college, university, and high school.  Interviews were conducted on 100 people from different places in the state and results were recorded, and analyzed.

MARKETING PRINCIPLES Essay Example | Topics and Well Written Essays - 1000 words

MARKETING PRINCIPLES - Essay Example Take for example the case of Inotada Knife Productions in Sakai-City, Japan. This firm produces extremely high quality, hand made kitchen knives, in very love volume and as such represents a behavioral segmentation. As it is the case that there are many manufacturers of knives across the globe many of which are much cheaper it could be argued that the reasoning behind why a company such as Inotada can stay successful is because the firm focuses on the product and not on marketing or planning. As it is the case that the company is already producing a high quality product in relatively low volumes one could argue that this strategy was already employed by the firm. As highlighted in the case, after PKD was no longer a supplier to major retailers such as Brown Thomas it became the case that the primary delivery method of his product offerings was through cold calling, trade shows, and a small amount of advertising and as a result the majority of his orders are between 300 and 1,500 euros mainly to boutiques. However it is the case that this may exert a greater level of control of PKD over its product offerings it may not be the best method for profitable growth. By ignoring a marketing and planning approach, the company ignores possible cost saving strategies through economies of scale. Furthermore it is the case that PKD means nothing to people who have never heard of the brand as such it may be the case that the company should spend significant efforts at promoting the pr oduct through alternative means. Lastly it is the case that whilst PKD may be ignoring marketing and planning, many of their competitors are not. If it is the case that A Nigella Lawson branded house wares product is of similar quality and price but has a brand that is recognizable to consumers it may ultimately be the preferred choice. Question #2- This answer will ultimately provide

Video Game Causes Behavioral Problems Psychology Essay

Video Game Causes Behavioral Problems Psychology Essay Firstly, one of the major concerns of video games is that they increase the nature of violence among the youth. The Harvard medical school or the Journal of adolescent health, as well as the British medical journal have concluded that there is a huge link between video game and violence. Researchers have found out that there is a certain pattern between video game and the behavioral problems associated with the video games, and Television shows. Scholars and researchers have said over and over again that Video games make kids more violent each time they play the game. A research was done which was brain scanning of children who played violent games like Call of duty the study showed that the answer was yes. Video games do make kids more violent. Researchers at the University of Indiana said that brain scans of kids who played a violent video game in comparison to kids who played no games showed a negative increase in the emotion of those children who played the game. According to aut hor Vince Mathews, parents should look more closely at the types of games their children are playing. He said I think parents should be aware of the relationship between violent video-game playing and brain function. Video games cause addiction which leads to children spending considerable time playing games resulting in neglect of more important activities. Perhaps excess of anything is bad and video games are no exception. In his article Video Games Addiction, Media literacy specialist, Dr. Charles Ungerleider states that if a youngster becomes addicted to video games it can be a problem. He explains that wanting to improve their gaming skills is not a problem in itself, but it becomes a problem if video games are taking a youngster away too much from other activities. Then the parent has to intervene and limit the amount of time the youngster spends with the video game. According to Mary Schlimme in a 2002 article titled: Do We Need a Video Gamers Anonymous? Video game addicts are often described by clinicians in the field as displaying many symptoms characteristic of other addictions. According to her article, Addiction includes such behavior as failure to stop playing games, difficulties in work or school, telling lies to loved ones, decreased attention to personal hygiene, decreased attention to family and friends, and disturbances in the sleep cycle. Schlimme quotes Dr Orzack that many game addicts have struggled with finding their place in society and as a result play video games in order to become part of a crowd. This in turn influences the game players to show off their achievements in front of their associate group. Excessive video game playing may not only cause behavioral and social changes in a person, but it may also result in neurological changes. Fourth paragraph third argument Even if video games and videos do not directly create killers and murderers out of the young people they may tend to contribute towards insensitivity and indifference towards violence. This is worrying because it may change the profile of the society in the longer run. In an article published in the Time Magazine on 10th May 1999 author and editors Joshua Quittner, Maryanne Buechner and Jay Ehrlich say The question isnt whether games make children kill, because it isnt that simple. The concerns are subtler yet no less worrisome. Do graphically violent games desensitize children to violence? Do such games teach kids to take pleasure in the suffering and death of others? Nicholas Carnagey, an Iowa State psychology instructor and research assistant, and ISU Distinguished Professor of Psychology Craig Anderson and Brad Bushman wrote published an article The Effects of Video Game Violence on Physiological Desensitization to Real-Life Violence in the Journal of Experimental Social Psycholo gy. In this paper, the authors define desensitization to violence as a reduction in emotion-related physiological reactivity to real violence. Their latest study tested 257 college students (124 men and 133 women) individually. The results demonstrate that playing violent video games, even for just 20 minutes, can cause people to become less physiologically aroused by real violence. According to the article It appears that individuals who play violent video games habituate or get used to all the violence and eventually become physiologically numb to it. Fifth paragraph Transition Paragraph Supporter of the video games do not seem to take the issues seriously. Despite this overwhelming evidence that video game causes violence and behavior problems in many developing children and in adolescents there are supportes who believe that there are advantages to video games in todays society. Key finding states in a research titled Internet Fantasy Violence: A Test of Aggression in an Online Games carried out in 2005 by Williams, D. Skoric, M states there was no effect on levels of aggressiveness or in belief and behaviors of the gamers who were engaged in a violent massive multiplayer online role-playing game. Cheryl K. Olson, professor of Psychiatry at the Harvard Medical Schools Center for Mental Health and Media, in her 2004 article in the journal Academic Psychiatry Media Violence Research and Youth Violence Data: Why Do TheyConflict? examines statements about the relation between violent video games and real-life violence. First, Dr. Olson notes that there is no evidence that targeted violence has increased in Americas schools. While such attacks have occurred in the past, they were and are extremely rare events. She goes on to write that, Theres no indication that violence rose in lockstep with the spread of violent games. In a 2002 presentation that updated their earlier comprehensive review of the literature on games and violence, Dr. Van Eeenwyk from the Washington State Department of Health presented information indicating that after controlling for psychosocial factors, association between aggression and playing video games was not statistically significant. This review was based on available objective research and was conducted by the State of Washington at the request of the state legislature. MIT professor Hennery Jenkins points out, 90 percent of boys and 40 percent of girls play video games. The overwhelming majority of kids who play do NOT commit antisocial acts. And, à ¢Ã¢â€š ¬Ã‚ ¦ the strongest risk factor for school shootings centere d on mental stability and quality of home life, not media exposure. Supporters of video games say that Professor Jenkins is trying to say is its not the video games that cause the violence, its completely different factors. Critics claim that video games are addictive has also been refuted by some supporters of the video games. In a response to a proposal in 2007 to designate video game addiction as a mental disorder akin to alcoholism, doctors and supporters of video games opposed the proposal. There is nothing here to suggest that this is a complex physiological disease state akin to alcoholism or other substance abuse disorders, and it doesnt get to have the word addiction attached to it, said Dr. Stuart Gitlow of the American Society of Addiction Medicine and Mt. Sinai School of Medicine in New York. The supporters of video games rgue that video game, computer and television provide education to children, that it provides help with their studies as well as educational institutio ns are using video games as one of the material for teaching. According to child experts and psychologists Video games give the childrens brain a real workout.   In many video games, the skills required to win involve abstract and high level thinking.   These skills are not even taught at school.   Some of the mental skills trained by video games include: Following instructions  and Hand-eye coordination Research also suggests that people can learn i visual attention skills from video games.   There have been even studies with adults showing that experience with video games is related to better surgical skills. Some supporters of video games say that video games teach children to plan and build their strategic thinking. children learn while playing video games. Steven Johnson, author of Everything Bad is Good For You: How Todays Popular Culture is Actually Making Us Smarter, calls this telescoping. Gamers must deal with immediate problems while keeping their long-term goal s on their horizon. Sixth paragraph Refutation of opponents counter- argument While there are researchers and supporters who claim that the video games do not have an effect on the increase in aggression and violence in the behavior of the gamers, yet those researches and studies are not based on modern scientific lines. Those studies are not as comprehensive and as scientific as those carried out by Craig Anderson, David Grossman or others. The supporters studies are generalized and are based more on hypothetical basis rather than actual scientific methodology. As proved by the various researches quoted above, their findings are flawed. Seventh paragraph Refutation of opponents counter- argument Supporters of the video games say that video games are healthy and educational. They claim Video games give the childrens brain a real workout.   In many video games, the skills required to win involve abstract and high level thinking. However, the fact is that addiction to video games causes not only health and other problems, including social ones, but also results in poor school results and grades, lack of concentration to academics and class activities. The critics have always disputed this claim about video games contributing to health and education. Dr. Louis Kraus of the American Academy of Child and Adolescent Psychiatry and a psychiatrist at Rush University Medical Center, has stated The more time kids spend on video games, the less time they will have socializing, the less time they will have with their families, the less time they will have exercising. They can make up academic deficits, but they cant make up the social ones, he said. Researcher Douglas Gentile, from Iow a State University, found that 8.5 percent of 1,178 youths studied are addicted to video games, using the same standards for addiction used for pathological gamblers. As a result of this, one in ten youths, may be suffering from family, social, school or psychological damage. In the case of video game addiction, the youth studied were found to have attention deficits in school, resulting in lower grades and even health problems. Video game addiction may be a sign of an underlying problem, such as depression. says Doug Gentiles report. Final paragraph Conclusion. Based on the above research it is clearly evident that violent video games contribute to the aggressive and violent behavior and addiction to video games. However, considering some of the advantages of the video games, their use must not be prohibited. Parents and guardians should do the following to reduce the effect of violence. Monitor video game play the same way one needs to monitor television and other media. Parents are responsible to be kind, loving but at the same time attentive and firm to properly discipline their wards. An aggressive child is more a product of dysfunctional parenting than anything else, including violent games and TV.   To avoid possibilities of addiction, parents should attempt to provide a variety of entertainment to their children. It would be a good idea to make sure that children read quality books, involve themselves in sports and interact with other children and their friends.

Personal Narrative About Me :: Autobiography Essay, Personal Narrative

Me I am sentimental, out-going, indecisive, understanding, curious, naive, lazy, and young. I want to be ... , well a lot of things, and growing is discovering what they are. I feel people cannot see the potential within, although there is no one to blame but myself. I look to others for approval instead of to myself. I aim to please; it leads to approval. I don’t like to discuss my faults; I pity myself. I am weak in some respects, but in others I am strong. My life is a balance of ups and downs. With my extremes however, my scales never fulfill the word "balance." The ups and downs equal a median on which I travel daily. I love those who understand me, who chose to come close to the fire, who stay long enough to love its warmth, and who know how to avoid being burned. I don’t trust people easily. I don’t throw around my heart. I’ve lost love from my lack of giving. I regret this. I grab hold of things, always seeking support, a rock on which to lean. I have tried God, boyfriends, and small successes in school and sports, feeling the title FAILURE rise upon my forehead when I slipped. Afterwards I tried even harder to bring myself back up, my recovery taken on the quickest, most unstable route. This explains how I fell so easily. The self-esteem I had needed to be constantly replenished and refilled. My source was not myself, but others, whose opinions mattered more than my own. I am passionate and at times fearless. I am everything, and I am nothing. I am ever-changing and unpredictable. I crave security but cry for independence. I am black or white, never gray. My actions may not reflect my feelings and vice-versa. I play the submissive female one minute and the aggressive female the next. Every year I learn more about myself. The person inside no longer takes peeks at the world outside, but screams "Look at me, see what I’ve become, watch because I am coming!" I’ve been through difficult times, but the odds are starting to lean my way; I feel ready for any challenge that may arise.

The Political and Moral Framework The WritePass Journal

The Political and Moral Framework References The Political and Moral Framework Introduction The existing relationship between morality and law is both interlinked and complex. Morality may be interpreted as a collection of beliefs values and principles which can vary between individuals. The law however is usually interpreted as those principles and rules which direct and enforce certain types of behaviour in society can be punished. However there are many grey areas where it is difficult to reach agreement over morality and standards of behaviour in our society (Martin J, 2010). Positivism emphasises the separation of morality and law, pointing out that law is the group of official rules and regulations found in legislation, legal opinions and constitutions. It is used to govern a society and to control the behaviour of people. Law therefore is a formal aid to social contrast and legal systems are a route to establishing and keeping social order in society. Natural law theorists point out that if a law is not a moral one there is no reason to obey it, whereas positivists believe that until a law is changed, it is the law and should be obeyed. Morality requires the conforming to by following standards and principles, â€Å"a religious code of conduct†, a moral right, â€Å"a claim people would think is justified but not necessarily supported by law†. Morality is very personal to an individual, but law covers society. However in a legal system there is an overlap between legal and moral rules. Telling lies or acting dishonestly is usually thought to be morally wrong, and dishonesty in some circumstances may be thought as legally wrong (http://sixthformlaw.info (17th March 2011). The Hart – Fuller debate pointed to Hart’s belief that no necessary link between a legal system and ideas of morality existed. A legal system, he believed can function effectively though it is neither moral nor just. The Nazi regime, in his view was a legal system as the Nazis argued that racial distinctions were relevant and reflected the morality of their society (http://sixthformlaw.info (17th March 2011). Both Hart and Fuller agreed however that immoral and unjust legal systems were very likely to be unstable and short lived. By lacking morality and justice the allegiance of the people will not follow therefore repression of the people will result. When repression fails, the system will fail. Devlin (1959) pointed out that â€Å"law without morality destroys freedom of conscience and is the road to tyranny†. He argued that criminal law must respect and reinforce the moral norms of society to keep social order from breaking down. (http://sixthformlaw.info (17th March 2011) Law and morality are intertwined and both dictate the manner in which people are expected to behave. The making and passing of laws is heavily influenced by moral viewpoints and these have a very large effect on the progress of law. However in our society, morality and law do not happen at the same time, as one evolves and the other can be instant. Morality is a set of beliefs, values, standards and principles of behaviour, with individual morals varying from person to person (Martin J, 2010). Individual morality may be different to the accepted public or society morality. Moral values are almost always linked with beliefs and can be influenced by religious beliefs. In our society there are very many different religious views and these can be seen to influence and affect moral values within a particular religious group or society. Moral values are only morally binding within a society or group, they are not defined as the law. These values have usually been formed and have developed over a lengthy period of time and cannot be deliberately changed as they have slowly evolved. If changes are to be made then the changes will be gradual and be guided by the will and desire of the people, these changes will obviously take time to evolve. Moral values are almost a voluntary code of conduct and lifestyle and are followed and obeyed because of the possibility of guilt and shame being present if these values are not kept. However there are no punishments if the code of moral values is broken, but some religions may have the power to excommunicate or expel which, within that society, will act as a powerful deterrent to breaking the existing voluntary code of moral behaviour. Morality relies heavily on the individual sense of guilt or shame for its effectiveness (Martin J, 2010). The law however has different and separate rules which guide any conduct. It is binding and is enforceable. The law is able to be altered by legislation and can be changed almost immediately. However the code of conduct is obeyed because of an already existing sense of moral duty and the code is relevant and reasonable, but when the rules are broken some form of legal penalty is usually imposed. This contrasts sharply with morality aspect in which there are usually no punishments for breaches of that code (Martin J, 2010). There are many laws in the country that reflect the moral values of the vast majority of its people. There is also the overlap between morality and the law, as in murder being a crime and also being morally wrong. The law does appear to be based on moral positions but some are not accepted by everyone. The legalisation of abortion in the Abortion Act 1967 serves a vital need to protect the safety of women so that they could have abortions in safe, hygienic clinics under proper conditions (Martin J, 2010). Even with something as protective as this Act, some groups such as â€Å"Life† and â€Å"Lawyers for the Defence of the Unborn Child† fiercely opposed the morality of abortion. The Catholic Church argued that abortion is always wrong as in its belief, life begins at conception. Another contradiction involves sexual morality and the law, with people arguing that sexual conduct outside marriage is wrong, but it is not against the law, as with incest and adultery. Both are classed as morally wrong, but of the two only incest is against the law (Martin J, 2010). However the positivist stance is that properly constructed legal rules must be obeyed, regardless of morality issues or popularity in society (Martin J, 2010). The Wolfenden Committee, asked to examine and consider a variety of moral issues in 1957, recommended the legalisation of both homosexuality and prostitution. There was a lot of debate over these two issues which included the treatment by courts of cases involving both issues. Evidence was taken for three years and the committee concluded that the job of the law is to preserve public decency and public order whilst protecting the public from offensive and injurious actions, also to provide safeguards against corruption and exploitation particularly for those who are vulnerable in society. The Committee also stressed that the law did not exist to interfere in the private lives of the public or to enforce patterns of behaviour. The three main recommendations of the Wolfenden Committee were; Soliciting in the streets – should be classed as an offence. This resulted in the Street Offences Act 1959 and made soliciting illegal and aimed to protect citizens in the streets from being solicited or harassed by prostitutes (Price N, 1957). Homosexual acts – between adults in private should be decriminalised (criminal law should not interfere with private lives of citizens) This recommendation became part of the Sexual Offences Act 1967 and applied to men over 21 yrs of age, later reducing to 18 yrs of age in 1994 and to 16 yrs of age in 2000 (Price N, 1957). Prostitution – should be a private matter and not subject to interference by the law as it was a commercial act (Price N, 1957). Such was the nature of these recommendations that judge Lord Devlin and Professor Hart took opposing sides. Lord Devlin’s stance, that the findings of the Committee in which the law has no business with private morality criticised the findings. He said that private immorality harmed the public and that stability in the society is achieved through cohesion, therefore the law should safeguard it. His views were used by the courts in Shaw v DPP (1961) and R v Gibson (1991) and by the House of Lords in R v Brown (1992). Professor Hart supported the opposite view to Lord Devlin and backed the findings of the Wolfenden Committee. He argued that the moral standards in society have changed through the years and that departing from accepted standards of sexual morality by consenting adults has not threatened society. His views were followed by R v Wilson (1996) and R v Brown(1992) in the Court of Appeal. The Wolfenden Committee recognised that the law has a function to provide safety against corruption and exploitation of people, but Lord Reid argued that people who choose to corrupt themselves have that choice, it is their affair to do it and the law should not interfere. However, he continued that no licence should be given to anyone to encourage this practice. The effect of morality on English law therefore was considerable and even the European Court of Human Rights became involved when the case R v Brown (1994) was heard. This case involving homosexual sado-masochistic acts, resulting in injuries, demanded that they should be treated as unlawful although happening in private between consenting adults. The House of Lords ruled that a breach of the law of criminal assault had occurred. The defence of consent was not upheld despite the pleas from Lord Slynn and Lord Mustill claiming that the courts were not to protected people from themselves (Martin J, 2010). However the Court of Appeal in R v Wilson (1996) found that a wife could consent to her husbanding branding to her buttocks with a knife. Morals played a part in this ruling the court found that it was not their duty to interfere in the private acts between husband and wife (Martin J, 2010). These decisions again had an effect on morality, particularly when finding that private actions were not the concern of the courts, despite them seemingly being against the law. In criminal law, morality plays a large part, particularly when sexual offences are being committed. Offences of homicide and those which are not fatal acts are linked to the moral viewpoint that it is wrong to physically harm or even kill anyone without justification. The impairing of reasoning because of an abnormality of the mind – diminished responsibility, has been accepted and it is now wrong to convict a person of murder if he has that condition under The Homicide Act 1952 (Martin J, 2010). Refusing a blood transfusion on religious grounds, ensures that it cannot be given or would bring a charge of committing a criminal act, if the blood transfusion was given, even if a child’s life was in danger (Martin J, 2010). In recent years there have been cases of terminally ill patients wishing to die. No one can consent to aid their own death. Anyone assisting a person to die is guilty under the law of assisting suicide. A case of this nature was R v DPP (2001) brought about by the husband of Dianne Pretty. Her application to the courts that if her husband helped her to die he would not be prosecuted, was refused in the House of Lords despite public sympathy and approval. The ruling that her husband would be guilty of a criminal offence was upheld (Martin J, 2010). Before 1961 it was a criminal offence to commit suicide, as failure to do so when attempting suicide ensured prosecution for the offence. The law now has changed, and morality does influence the law as suicide attempts which fail are not always prosecuted (Gardner J, 2011). There are however several exceptions to the public policy of consent when assault charges are involved resulting injuries. These exceptions are usually found in examples from games or sports, tattooing, reasonable surgical acts, body piercing and horse play. These have been allowed because of general public interest, consent is accepted as a defence in these instances (Martin J, 2010). Finnis (1980) claimed that the law makes a moral claim for it-self and means that an ideal type of law (the paradigm) is a morally justified law. If the moral claims made by the law succeed in its moral aims, it is morally justified law. It is the law that lives up to the moral standards (Gardner J, 2011). A legal rule may be morally justified as it is applies to one action and not as it applies to another, in the same way it applies to one person and not as it applies to another person. It is therefore hard to imagine that any law has all the moral force that it claims for itself. The moral problem of the law is how or why it speaks to morally decent people, why it is trying to direct people to accept by claiming moral authority (Gardner J, 2011). The law always tells people what they must do without including virtue or advantage as being part of the law. It requires actions in the interest generally. One of the problems with morals is that they are wholly subjective and vary in application from one group or society, to another. What is frowned upon as immoral in one society may be tolerated in another (Green L, 2011). This can and does cause problems, particularly in cases such as abortion or adultery. These are both legal issues, but many believe to be immoral. Gillick v West Norfolk and Wisbech A.H.A (1986) showed that a mother challenged her daughter’s doctor for issuing contraceptives. The mother lost the first hearing, won in the Court of Appeal but lost again in the House of Lords. The whole case led to children having greater rights to make their own decisions on matters like medical treatment. â€Å"Gillick Competent† was a phrase coined for this development in the moral issue. Both morals and law involv e rules as the courts enforce the law but not social rules. If the morality is a shared belief then most people will obey the rules (Martin J, 2010). In conclusion, it is clearly shown that the relationship between the law and morals is a complex and intertwined one. They both dictate the manner in which people are expected to behave in their everyday lives and how moral beliefs can have a great influence on the making of laws. It is argued by some that many aspects of criminal law represent a common moral stand point. The moral standing of a community has an influence on the development of present and future law. The views of the Wolfenden Committee, Professor Hart and Lord Devlin feature strongly in moral and legal issues, with Lord Devlin maintaining that the law should support moral principles, even if public opinion changed. Professor Hart took a different a different and opposite view to that of Lord Devlin, arguing that there should be a clear separation of law and morality. Even when contradictions in law are shown, R v Wilson (1997), in an apparent criminal act, the crime was not punished as the Court of Appeal ruled that it was consensual, a private matter, and the law should not interfere. From the 1980’s and in some areas, earlier in time, rules and laws came about through custom and established practices whereby the community would show a united disapproval if a practice was broken. Legal sanctions were not used. In modern times there are changing morals, increasing numbers of laws and development of both. As these are almost always intertwined, our society appears to depend more on the law and its rules than on many previously held moral beliefs.

Whats Tested on the SAT Math Section Topics and Practice

What's Tested on the SAT Math Section Topics and Practice SAT / ACT Prep Online Guides and Tips Your first step in preparing for the math section of the SAT should be familiarizing yourself with exactly what’s on it. Whatever math class you’re taking in school, you should be able to conquer the SAT math topics with the right approach to test prep. Let’s start this guide by reviewing the overall format of the math section of the SAT. SAT Math Format Math will be your third and fourth sections on the SAT, right after Reading and Writing Language. You’ll first get a 25-minute section, during which you can’t use a calculator. After a short break, you’ll move onto the 55-minute section. During this longer section, you’re allowed to use your calculator. Both sections will begin with multiple-choice questions, each of which will feature four answer choices. Then you’ll be asked for some student-produced responses, more commonly known as "grid-ins." On the calculator section, some of these grid-ins will relate to one another as part of an Extended Thinking question. // Here’s the breakdown of time, number of questions, and question types on the two SAT math sections. Section Number of Questions Time No calculator 15 multiple choice, 5 grid-ins 25 minutes Calculator 30 multiple choice, 8 grid-ins (including one Extended Thinking question) 55 minutes Total 58 questions 80 minutes While you can only use a calculator on the longer Math section, you’ll have access to the following reference information for geometry in both sections: Of course, you’d be better off having this information memorized than wasting time flipping back in your test booklet to these formulas. This material isn’t actually all that important on the math section, as geometry problems make up less than 10% of the questions. That being said, what skills and concepts are most prevalent in the math section? Content is king! Or, at least, it's very important to master before you take the SAT. SAT Math Topics // While the math section doesn’t place a large emphasis on geometry problems, it does focus on algebra, solving equations, and data interpretation from tables and graphs. College Board sorts the question types into three main categories: Heart of Algebra, Passport to Advanced Math, and Problem Solving and Data Analysis (they apparently gave up on the creative naming once they reached the third category). These three realms describe about 90% of the SAT math questions. The remaining 10% are simply called Additional Topics, and they mainly include geometry, basic trigonometry, and complex numbers. Let’s take a closer look at each of these categories by going over the SAT math topics and skills they test. After a description of each one, you’ll see three official sample practice questions from College Board. Heart of Algebra SAT math questions in the Heart of Algebra category have to do with linear equations, inequalities, functions, and graphs. Below are the official topics as defined by College Board, followed by a summary of tasks you’ll need to be prepared for to tackle these questions and some example problems. // Official Topics Solving linear equations and linear inequalities (in these expressions, x is a constant or the product of a constant) Interpreting linear functions Linear inequality and equation word problems Graphing linear equations Linear function word problems Systems of linear inequalities word problems Solving systems of linear equations Summary of Tasks // Use multiple steps to simplify an expression or equation or solve for a variable. Solve for a variable within functions or systems of inequalities with two variables (usually x and y). Determine whether a given point is in a solution set or what value would make an expression have no solution. Select a graph that shows an algebraic equation, or, on the flip side, choose the equation that describes a graph. Indicate how a graph would be affected by a given change in its equation. Sample Questions Solving systems of linear equations: Solving systems of linear inequalities: Graphing a linear equation: Grab your passport- we're crossing the border into the land of advanced math. // Passport to Advanced Math While Heart of Algebra questions are focused on linear equations, Passport to Advanced Math questions have to do with nonlinear expressions, or expressions in which a variable is raised to an exponent that’s not zero or one. These questions will ask you to work with quadratic equations, exponential expressions, and word problems. Read on for the full list of topics that fall under Passport to Advanced Math, followed by a summary of tasks and three sample SAT questions. Official Topics Solving quadratic equations Interpreting nonlinear expressions Quadratic and exponential word problems Radicals and rational exponents Operations with rational expressions and polynomials Polynomial factors and graphs Nonlinear equation graphs Linear and quadratic systems Structure in expressions Isolating quantities Functions // Summary of Tasks Solve equations by factoring or using other methods to rewrite them in another form. Add, subtract, multiply, or divide two rational expressions or divide two polynomial expressions and simplify your results. Select a graph that matches a nonlinear equation or an equation that corresponds to a graph. Determine the equation of a curve from a description of a graph. Figure out how a graph would change if its equation changed. Sample Questions Functions: Nonlinear expressions: // Nonlinear equation graphs: Problem Solving and Data Analysis This third and final major category includes questions that ask you to work with rates, ratios, percentages, and data from graphs and tables. Read on for the official topics, a summary of tasks, and three sample questions. Official Topics Ratios, rates, and proportions Percents Units Table data Scatterplots Key features of graphs Linear and exponential growth Data inferences Center, spread, and shape of distributions Data collection and conclusions // Summary of Tasks Solve multi-step problems to calculate ratio, rate, percentage, unit rate, or density. Use a given ratio, rate, percentage, unit rate, or density to solve a multistep problem. Select an equation that best fits a scatterplot. Use tables to summarize data, such as probabilities. Estimate populations based on sample data. Use statistics to determine mean, median, mode, range, and/or standard deviation. Evaluate tables, graphs, or text summaries. Determine the accuracy of a data collection method. // Sample Questions Calculating data based on rate: Scatterplot and calculating rate: Calculating percentage based on table data: These next few categories don't quite fit anywhere else. Additional Topics in Math While 90% of your questions will fall into the Heart of Algebra, Passport to Advanced Math, or Problem Solving and Data Analysis categories, the remaining 10% will simply be classified as Additional Topics. These topics include geometry, trigonometry, and problems with complex numbers. Official Topics // Volume word problems Right triangle word problems Congruence and similarity Right triangle geometry Angles, arc lengths, and trig functions Circle theorems Circle equations Complex numbers Summary of Tasks // Determine volume of a shape. Apply properties of triangles to determine side length or angle measure. Apply properties of circles to measure arc length and area. Solve problems with sine, cosine, and tangent. Sample Questions Right triangle problem with trigonometric functions: Congruence and similarity: Angles and parallel lines: To truly prepare for the math section of the SAT, you should make sure to review all of the above mentioned topics. Some problems, furthermore, will integrate topics and require you to apply multiple skills and concepts as you work toward a solution. Multi-step problems are prevalent throughout the math section. Let’s take a closer look at multi-step problems, along with the other main features you need to be aware of as you prep for SAT Math. // Grab your snacks and turn off your cell phone- it's time for the main feature(s)! What Are the Key Features of SAT Math? In addition to understanding content and format of the SAT Math section, there are some key features you should know about. As you study, keep an eye out for these features. By familiarizing yourself with them, you may even be able to use practice materials for the old SAT effectively to prepare for the current SAT. Multi-Step Problems You may notice that several of the above problem types state that they require multiple steps to solve. While wording of math questions should be straightforward, the thinking and calculations required will be relatively involved. To prepare, you'll especially want to focus on time management and working quickly and efficiently. // To solve a word problem, you may have to combine skills from one more than one content area or use several steps to get to your answer. Word problems may present a long scenario, and you’ll need to figure out what data to use and what concepts to apply to get to your answer. Speaking of word problems... Emphasis on â€Å"Real World† Applications According to College Board, much of its purpose behind redesigning the SAT was to make the test more closely aligned with classroom learning and real world skills. As a result, the math section won’t feature too many abstract reasoning questions. Instead, the word problems will be grounded in realistic situations. Some may ask you to calculate gas left in a car’s gas tank or the conversion of money from one country’s currency to another. Most word problems will present scenarios that you might encounter in your life. // There will be a few questions that test your understanding of sines. Also, cosines and tangents. A Few Geometry and Trigonometry Questions About 10% of the questions will feature geometry and/or trigonometry. Since not everyone has studied trigonometry in school by the time they take the SAT, these questions may call for separate, SAT-specific preparation. You should acquaint yourself with the relevant concepts and formulas, but focus most of your energies on preparing for algebra, functions, inequalities, graphs, and word problems. A No-Calculator Section and a Calculator Section For 25 minutes, you won’t be able to bring out your calculator to answer any of the math questions. There’s no need to worry! The problems in the 25-minute section won’t require a calculator; in fact, using one on those problems would probably just slow you down. // Calculator fluency, or knowing how and when to use your calculator effectively, is an important skill on the SAT math. The College Board says, â€Å"Calculators are important tools, and...you’ll need to know how - and when - to use them...The calculator is, like any tool, only as smart as the person using it. The Math Test includes some questions where it’s better not to use a calculator, even though you’re allowed to.† So you definitely won’t need one on the shorter â€Å"no calculator† section, and you may not even need one on many of the problems in the longer â€Å"calculator† section. Answering lots of practice questions can help you get better at deciding when a calculator would be helpful and when it would just slow you down. An Extended Thinking Problem A few of your questions will be part of an Extended Thinking problem. Typically, this Extended Thinking problem will be part of the grid-in questions near the end of your 55-minute section. // Basically, you’ll get a graph, table, or word problem scenario and then have to answer multiple questions about it. The following is one example of a word problem-based Extended Thinking question. Notice the bent toward â€Å"real world† application! Grid-in Math Questions Speaking of grid-ins, you'll have thirteen of these student-produced responses that you'll answer in a special part of the bubble sheet at the bottom. While you can write your answer in the spaces provided, you'll have to fill in the corresponding bubbles for credit. There are bubbles for digits between 0 and 9, as well as for decimal point (a period) and fraction line (a slash). To practice gridding in your responses, you can practice on College Board's SAT practice test answer sheet. As long as you're familiar with the key features and directions of SAT Math, you can hit the ground running and not waste time figuring out logistics. So whether you're prepping with PrepScholar, online practice questions, official College Board tests, or a combination of all of these, how should you approach prepping for SAT Math? // Unleash the power of prep. How You Should Study SAT Math Many of the concepts on SAT Math you'll learn in your math classes in school. This doesn't mean that classwork will prepare you enough to perform well on the SAT, though. SAT Math questions test the above concepts in a unique, SAT-specific way. In order to prepare and learn to be speedy in your time management, you'll want to practice and get familiar with the wording with high-quality practice questions. Official practice tests will also help you uncover and diagnose your strengths and weaknesses. If you find yourself consistently stumped by function questions, for example, you'll know to focus your energy and studying there. Even if you haven't taken an advanced algebra or trigonometry class yet in school, you can still prep for these questions by studying SAT concepts and questions. If you're strong in math and looking to achieve a top score, you want to approach the math section in a strategic way.

Desiree's baby by kate chopin Essay Example | Topics and Well Written Essays - 750 words

Desiree's baby by kate chopin - Essay Example Regarding her as Providence’s most beneficial bestowment, Madam Valmonde, the childless rich woman raises her. The nameless little girl becomes Desiree and grows up to be â€Å"beautiful and gentle, affectionate and sincere†. At the age eighteen, Armand Aubigny spots her near the stone pillar at the gateway of Valmonde and falls in love with her and eventually marries her and takes her off to L’Abri, his place. The story begins when Madam Valmonde sets out to see Desiree’s baby. It is four weeks after the birth of the baby that she finally drives to L’Abri to Desiree and the child. The reasons behind this, whatever it may be, are not discussed in the story. Obviously it is not on account of any animosity between the two households. It is made clear in the story by the way Madame Valmonde’s thoughts go about the past fondly recollecting how Desiree landed into her lap and grew up to be her idol. On reading L’Abri, the surrogate mother sees the new mother and child. At the very sight of the four weeks’ old child, Madame Valmonde gets startled but Desiree is unaware of the reasons and she quite naively attributes it to the rapid growth of her dear child. She talks nonstop about how the child has exerted a softening impact on the temperament of its father who is basically imperious and exacting in his ways. Desiree senses trouble only much later, after two months, when she feels her husband’s awkward avoidance of her. It coincides with her noticing of the fact that her child was not white. The moment of this realization is marked in the story thus, â€Å"The blood turned like ice in her veins, and the clammy moisture gathered upon her face†. Having understood the cause of the great change in her husband, Desiree confronts him directly seeking reassurance and solace. But he brutally lets her down by declaring that the child is not white because of her black lineage. She resorts to the next thing she had to do. She writes to Madame Valmonde as soon as

Mary, mother of god Essay Example | Topics and Well Written Essays - 500 words

Mary, mother of god - Essay Example First off, the purity of Mary presupposes that she was planned by God to be the extra-ordinary person far from any stains. She is an etalon of the female immaculate power able to touch on each and every heart and soul. She was blessed before she was chosen to bear Jesus in her womb, and, therefore, she was free from the wicked human nature, i.e. from sins as they are (Sheen 38). Thereupon, one is to remember that the blessing of Mary spread over those who once chose Jesus as their savior. On the other hand, at the moment of Mary’s conception she became the first effect of redemption and order of mercy as she came to refuge sinners (Shea 29). Thus, by praying to Mary one should understand her initial significance in the scattering of the first and foremost teaching out of the gospel. To say more, Catholics should not get themselves into the pit of fallacies forgetting about the rest of the Bible and the predominant role of Jesus Christ in saving the humanity. Mary is the beginning of the universal virginity salvation as she was immaculate enough that God beloved her to be the Mother of Child. Shea unveils the need for seeking God’s wisdom between Mary and saints by saying the following words: â€Å"Looking to a florid prayer to Mary or a saint is an excellent way to get a grasp of how Catholics with a strong Marian piety feel† (30). This is why the rational of prayer to the saints rediscovers and allegedly opens the way toward better understanding of the Mystical Body of Christ, meaning the Church itself. Mary could crush the cobra’s head, so to speak, by means of her as a medium between holiness of God and sins of people around. Given that, it is vital to amplify that Mary is the Mother of the â€Å"greatest man ever born of woman† and piety of Catholics leads to pure and clear understanding of God’s will (Sheen 73). Hereby, Mary, promulgates the birth of Jesus who brought the World’s teaching so vivid and
