Hagar Currie Shipley from the novel “The Stone Angel” by Margaret Laurence and Edgar Gallant Essay

Through the character Hagar Currie Shipley from the novel â€Å"The Stone Angel† by Margaret Laurence and Edgar Gallant, we can see that life experience and religion have certain affects on people which may change as they grow older. Those impacts can be for the good or the bad. These decisions are made by the people who experience something so great that had changed their minds. When someone goes thought something that might have changed their lives then they sometimes become a different person. Hagar Shipley is often found in contact with her past but not with her emotions. She had been thought a lot in her life and one thing was holding her back which lead her to make the decisions she did. On the other hand, Edgar Gallant, uses his emotions to share his past with his relatives and loved ones. Being this way Edgar became the person he is now. These two people are unique in their own ways but they still have certain similarities with their lives experiences. First Paragraph Hagar Shipley’s life experience has an important affect on her present self since she keeps on leaving the present whenever she feels uncomfortable. In her old age, she escapes the present through daydreaming and wanders around in her past in search of a situation where she had control instead of having to deal with the present situation. For example when Hagar is given Barium by the doctor at the hospital and she is wondering what will happen next: â€Å"I’ve waited like this, for things to get better of worse, many and many a time. I should be used to it. So many years I waited at the Shipley’s place†¦Ã¢â‚¬  We see here that Hagar does not feel comfortable in the present being given a substance she does not know. Therefore Hagar leaves the present in search of a situation she has been in previously where she knows what will happen. Hagar does not only escape from the present mentally but also physically. Even though Hagar is a very proud woman, she becom es progressively more powerless to care for herself and therefore becomes an unbearable tension on her son, Marvin and his wife, Doris. This tension becomes even worst as she takes a trip away from home leaving them stranded, not knowing where she has disappeared: â€Å"Oh dear, you threw an awful scare into us. Why should you go and do such a thing, anyway, mother? When I came back from the store, and found you weren’t there, I nearly when out of my mind. Its been so worrying for us, and we felt so awful, having to go to the police. They looked at me in such a funny way, as though I should’ve taken better care, but how on earth was I to know you’d do a thing like that?† We see here the problems that Hagar has inflicted upon her son and his wife. We do not hear very often of an old lady of ninety two years old running away from home. Hagar needs care because she has become a child. Hagar was never a child because her father made her grow up faster then her age. So as Hagar looks into her past at her childhood she sees a grown up child, so in her old age, she became the child she never was. Hagar’s college education was not a very important part of Hagar’s life even though it has prevented her to live the care free of a young growing women. In those days, college was not the same for girls and boys. We can see this through a quote from Jason Currie: â€Å"It’s not the same for you-there’s no women here to teach you haw to behave like a lady.† Jason was sending Hagar East to learn how to become a lady, not for work related knowledge. This is shown by Jason when Hagar come home two years later: â€Å"Do you think I sent you down East for two solid years just so you could take a one-room school?† Hagar’s father did not need her to learn to do any type of work, he had sent her there for her to be pretty and know how to behave herself like a lady to show off to the entire town to show off his daughter. â€Å"You’re a credit to me. Everyone will be saying that by tomorrow. You’ll not work in the store. It wouldn’t do.† We here realizes that Jason has sent his daughter Hagar to college so that he could be proud of her. Hagar is also very proud as we can see when her father hits her: â€Å"I wouldn’t let him see me cry. I was so enraged.† This is pride, she has inherited from her father. Her father then realizes that she will not let him see her cry and says: â€Å"You take after me, you’ve got backbone, I’ll give you that.† From this quote, we can see that Hagar’s pride comes directly from her father. Hagar once said:† â€Å"Pride was my wilderness and the demon that led me there was fear.† She has been afraid of being unrespectable which is why she decided to go to college and was easily convinced that it was she that should go and not Matt. Afraid of needing too much and giving too much, Hagarâ€℠¢s pride is both unsettling and inspirational. Second Paragraph Edgar Gallant’s life experience and past memories have an important effect on his life and relationships with others. Edgar had a very interesting past that affects him even today. His past affects his career as a volunteer in the later years of his life as he helps out others with his knowledge. He has been asked to take part in over a dozen organizations due to his previous success in his life’s work. Not thinking he has fulfilled his dream and what he was sent here to do, he has accepted to help out in about nine different association for the public usually as a president or vice president of comities. Edgar Gallant uses his past, not to hide, but to enrich his every day’s work. Unlike Hagar, Edgar has usually worked in a team thinking that several brains are better then one, sharing information to reach a better solution that one could not come up with alone. Edgar does not hide his emotions, he believes that hiding a certain part of them is good in the work environment because of the professional look and rational approach to have in a work environment with work partners. On the other hand, he is very open towards his family and shares everything with them. He has shared hi time between work and family always leaving enough time to carry on his duties as a responsible father. Sharing his feeling with his wife and children, he was able to create a feeling of trust and educate his children in the way he thought was best. Edgar found that sharing some degree of emotion show as well as the rational view of things was the best approach in family situation. It is good to show emotion to a certain degree. One does not want to overwhelm, but share his problems with his family. â€Å"I have always consciously made an effort not to let emotion dominate reason.† This shows that he shares his emotions with others but does not let them take over by keeping a rational look on things. Edgar was never really proud in the same way as Hagar. He was often given position he though were above his expertise, but decided that since others had that trust in him, that he would not deceive them so he went on to do what was expected of him, never letting anyone down. Third Paragraph Hagar’s take on religion has changed throughout her life. In her younger age, Hagar was very religious and went to church with her father. Then she found out that her father was having an affair with Lotions mother and since then she started being less religious. After John’s death Hagar stopped being completely religious. She prayed for him to live, but to no avail as she explained to Mr. Troy. She feels that praying is useless because god will not respond to her in the end. Edgar’s take on religion has also changed with age. When he was a boy, his family was very religious. At the age of 13, he was sent to a boarding school which had a priests where all his companions and teacher were extremely religious. As soon as he left the boarding school, he then realized that he did not agree with some of the religious concepts he was taught. From then on he decided to take a different look on religion. As he got old he leaned more about the world and that added to his concepts to religion which was also a reason why it changed. Just like Hagar, Edgar does not currently practice a certain religion but has beliefs of his own inspired from the Catholic Church and books. Edgar has changed his view on religion due to philosophical books, religious texts from other religions and his work which is about social justice and truth to the people. Due to his knowledge as he grew older, he has come to realize that not one religion is true, but that all of them have something good and that religious belief is a sum of all of them. He also mentioned that there is not way of knowing which religion is the right one so taking bits from all of them can maybe create a better understanding from all of them. He also did not let religion take over his life which enabled him to work more frequently. From her childhood as a daughter of a Scottish merchant to her marriage, Hagar has fought a long and wrong battle for freedom and respect. In the end she realises her wrong doings when it became too late, she has gone with her life without thinking about her actions and the consequences. When someone does not know if they are at fault they keep repeating those actions until its too late to reverse them. Edgar on the other hand has nothing to look back on, he knew exactly what he wanted and went right for it. In Edgar’s case he was raised by and worked hard to earn respect which in the end he was granted respect by others. The work he has done for the society is incredible and he is still doing so in a manner that will benefit the society and him self. He will not stop working until he probably can’t function anymore. The benefit that he is getting out of it is the joy of being able to make a difference. Hagar unfortunately realized this near the end of her life, when time was running out. She realized this when she only performed one task to help out the girl in the hospital. If only she realised that helping others is rewarding and makes a difference, then she could have started at an earlier age. Whether it’s a person’s character or religion, as one grows older their views change. This could include a change in heart or opinion.

Security Risk Management

Abstract In this paper, it’s have stress on importance of user in participate on information security risk management and its influence in the context of regulatory compliances via a multi-method study at the organizational level. Along with associated outcomes, the types of activities and security controls in which user’s participation as part of Sarbanes – Oxley compliance also understand here. Besides that, research model also been develop in this paper on the finding of the quantitative study and extant user participation theories in the system development literature.While the IS security literature often portrays users as the weak link in security, the current study suggests that users may be an important resource to IS security by providing needed business knowledge that contributes to more effective security measures. User participation is also a means to engage users in protecting sensitive information in their business processes. 1. 1 Introduction This a rticle is briefing about the problems that involved with information security example external threats likes hackers, viruses and people.There have two reason why user participate in IS security risk management very valuable. Firstly, user awareness of the risks to IS security is widely believed to be fundamental effective IS security (Aytes and Connolly 2004; Furnell 2008; Goodhue and Straub 1991; Hu et al 2006; Siponen 2000a,2000b; Straub and Welke 1998; Whitman 2004) and second is security control need to be aligned with business objectives to be effective (Alberts and Dorofee 2003; Halliday et al 1996; ITGI 2005; McAdams 2004; Suh and Han 2003).In this article concept of user participation have been characterized by extant theories and conceptualization in IS security contexts. The study’s multi – method research design is outlined and followed by a qualitative exploratory study that examined user participation in IS security risk management for regulatory complian ce. A theoretical model be informed by extant user participation theories and the qualitative study is then tested in a confirmatory quantitative study. 1. 2 Content In this article, security risk management was discussing with the user participation with it.Security risk management is a continuous process of identifying and prioritizing IS security risk and implementing and monitoring controls. User participation is expected to add value to SRM, which in turn contributes to effective controls that ultimately improve security. SRM have a combination with data that have been collected and analysis method that used on separate samples to examine user participation. There has two method in examines user participation such as qualitative methods and quantitative methods.Qualitative methods provides a rich understanding of the activities, behaviours and assignments that define user participation in the context of SRM for regulatory and allowed a process model to be constructed by applyin g the three user participation. Quantitative methods test the theoretical model derived from the qualitative study and based on the researchers understanding (Lee 1991). Combining this two methods provides a rich context and testability to the study (Tsohou et al. 2008).In this paper, Sarbanas – Oxley Act has be chosen for the study context as to mean locate an adequate sized sample of companies employing user participation in SRM. Sox has two reason why them encourages business participation in SRM. First, ICOFR focuses on business process that impact financial information on publicly reported statements and second technical controls geared toward protecting the network perimeter from external threats are insufficient to manage internal threats and vulnerabilities embedded within business processes.An exploratory study was conducted to better understand the specific activities, behaviours and assignments that constitute user participation in SRM and to investigate their outc omes. To conduct the exploratory study, informants with SOX experience were first identified and selected. Nine semi-structured interview were conducted with eleven informants from five companies in three countries, two interviews included two informants. A contextual narrative of user participation lays a foundation for a subsequent examination of the effects of participation studied through the lens of three extant user participation theories.This three theories are The Buy-In Theory, The System Quality Theory and The Emergent Interaction Theory. User participation in SRM was found to raise organizational awareness of security risks and controls within targeted business processes, and facilitated greater alignment of SRM with business objectives, values, and needs. As a result, development and performance of security controls improved. Thus, user participation was found to add value to an organization’s SRM. User participation’s effect was strongest in aligning SRM w ith the business context.In turn, users became more attentive as business-alignment increased. This finding suggests that users are likely to be more attentive when IS security is something to which they can relate. That is, when SRM becomes part of business processes, and users are assigned hands-on SRM tasks, security becomes more visible and relevant to users. Consequently, user participation may be a mechanism for managing user perceptions on the importance of security. Accountability was found to contribute most to user participation in SRM.One explanation for this finding is that the study context was regulatory compliance for a law that required annual external audits. This finding suggests that regulation may provide an opportunity for security managers to engage business users in security risks and controls when regulatory compliance has a business process orientation. Secondly, regardless of regulation, study findings suggest that efforts at accountability for SRM may be m ore effective if there are routine audits with documented results and follow-up for control deficiencies. 1. 3 ConclusionAlthough the IS security literature has often cited users as the weak link in IS security due to user errors and negligence, the present study provides evidence that supports an opposing view. User participation raises organizational awareness of security risks and controls within business processes, which in turn contributes to more effective security control development and performance. Security managers can harness regulatory compliance as an opportunity to engage users, raise organizational awareness of security, and better align security measures with business objectives. . 4 References Alberts, C. , and Dorofee, A. 2003.

Compare and contrast two European countries Essay

Compare and contrast two European countries - Essay Example Social exclusion and marginalization have been intensified by the several factors, which includes the following. The increasing disparities in educational and skill levels have led to several people staying out of the labor market because judgment is based on qualification. Long-term unemployment poses the individuals to the risk of segregation in the society. They may be denied access to opportunities due to their economic status. Male joblessness is another rising issue. This is brought about by the emphasis placed on gender equality. In the effort to combat the past inequalities, much has been done on the women and girl child part hence putting the male species at stake. (Atherton, 2003, p.81) Since more and more women are getting educated and are given first priority in the job sector men are at the risk of losing jobs. Another factor is feminization of an increasingly casualised work force. The widening gaps in income levels are creating bigger possibilities of social exclusion. The increasing gaps in income levels are building on social gaps between the rich and the poor. The rich gets richer and the poor is getting poorer. This makes it difficult for the poor to cope with the fast moving life. People who cannot fit in the high-class life are locked out to belong to a rather low class. (Atherton, 2003, p.85) Deteriorating health and life expectancies for the poor society members is on the increase. The poor cannot access to health services most likely after the superiors deny them them. Poor health leads to short life expectancy. The poor standards of living contribute largely to the rising mortality rates among the poor. The rich has enough income to eat well, have a dignified life, a good health and their life expectancy is higher compared to the life expectancies of the poor members in the society. (Ferguson, 1990, p.24) Social exclusion is at the centre of public discourse in all countries across the European Union. Most researchers and scholars use past data to create comparable indicators of social exclusion. Most of the comparable dynamic information was on a wide range of demographic, social and economic indicators across Europe. Almost half the employed age population is disadvantaged on at least one point in time. Very few people are likely to be sidelined on a large number of social exclusio

The Lottery Essay Example | Topics and Well Written Essays - 250 words

The Lottery - Essay Example his own trip up to the box to pull for his new family, he had stopped plotting with Nancy and now Davey who had become old enough to discuss the plan to stop the lottery. Davey didn’t remember Tessie nor remember the warm nights on the porch sipping lemonade that she made from tart lemons sweetened with sugar before pouring the water into the pitcher. Davey didn’t know her loss in a real sense, only through the pain of his sister and brother. He knew the pain of his father who sat in a chair staring out over the fields in silent resentment, cold and stoic as he accepted the fate of his wife, but not his own fate of raising three children on his own. It was Davey who moved to make their plans a reality. He had seen others who had fell to the stones, sacrificed for the good of the town. He sat for hours trying to see the connection between the horrific act of stoning the one and the success of the fields. He tracked the harvests year after year, noticing that some years were good and some were bad, never relating to the person who was stoned. He tried to show Mr.Summers that the lottery did the town no good. However, Mr. Summers had an excuse and argument to counter every point that Davey made. When Mr. Summers died, he tried again to speak to his father who surprisingly took over in running the lottery year after year, as if he could reconcile Tessie’s sacrifice by deeper participation. This didn’t change a thing. Nancy came up with the idea. The town gathered, the children made the pile of stones, and the tense, polite conversation began to murmur through the growing crowd. Bill Hutchinson raised hands and smiled, quieting the crowd to ready for the lottery to begin. The year before had been brutal as the five year old child of the village teacher had been the sacrifice, and mothers were noticeably more protective of their young ones, cradling them in their arms and turning slightly away. Janie held her a Bill’s child close, her lips kissing repeatedly

Pranent-Community Involvement Program - Essay Example California department of education is an organization that supervises public education. This organization aims to provide guidance, support, supervision and teaching sources with material; so that every student can get good education. Various researches have been conducted in order to study educational programs ranging from teachers` training strategies to parents awareness programs. By studying such education related programs it has been observed that all those programs which includes parents involvement in their kids` studies has been proven the most influential ones for the prosperity of children as well as for the success of educational system (Rutherford & Billig, 2010). Researches have shown that education standard has been improved because of the involvement of parents and family in school programs. There are five booming plans that have brought changes at National level in United States specifically in New York and California. Various benefits have been observed because of th is program and individuals belonging to education world appreciated parents for their interest in children studies and other activities that can help their kids to learn something innovative. It is considered very important that parents should try to understand the importance of their role in their child`s career and education because they are the only ones whose active participation can bring an incredible change in their children`s life (Rutherford & Billig, 2010). There are certain National Standards for parent community involvement programs which are based on qualitative research and are important for children`s career, parents satisfaction and for the success of educational institution. There are three motives of this standard that includes encouragement of parents and families for their active contribution. Secondly, to provide knowledge about all those influential elements, that can play vital part in such programs and also to give moral and material support to those institut ions that aim to raise their standard of education through various strategies and programs (Hurley & Tinajero, 2001). These are some important guidelines for principals and owners of the schools who wish to divert parents` attention towards child`s education through strategic programs. National standard intended to guide those people in very sophisticated manner who administer educational institutes because they have authority to deal with staff members and also they can apply such strategies within district level for parents to grab their attention as much as possible (Riley, Douglas, & Koop, 2004). According to amendments to community-based English tutoring program of California, when everyone plays its part to support learning system with full dedication, then children show positive response towards their studies and they show more interest in every school related activity. Many schools have adopted the program designed by California department of education which includes few bas ic goals. Their first goal is that they want to break all blocks that restrict parents` involvement. It is emphasized that parents should be made comfortable when they entered in school in order to encourage their spirit. All parents should be kept updated with their child`s academic progress (Hurley & Tinajero, 2001). To make it easier for parents to get information about institute and their kid keep updating websites or practice any other volunteer process that could

Immigrant Policies in America Essay Example | Topics and Well Written Essays - 1000 words

Immigrant Policies in America - Essay Example Immigration in modern day America is just as strong as it was when America was formed. Initiations by the American government such as the green card lottery are a means of attracting fresh faces to this already diverse country. The immigration debate is one of the biggest in America. Some native-born Americans forget that their ancestors were once immigrants and tend to harbor hostility towards new immigrants while others are more accepting. It is obvious that Americans have mixed feelings about immigration but many do not realize that immigrants also share mixed feelings about starting a new life in America. Modern day America is often referred to as a melting pot in which many different nations and people blend together to form a unique culture. Although this picture of America seems ideal, it is far from realistic. Immigrants who leave their home countries in order to come to America are sometimes left feeling out of place and confused. Immigrants are not sure how to balance their old culture with the new American culture. For example, Muslim immigrants who wear the traditional hajib often feel as though they are discriminated against thus are forced to conceal their true identity this leads them to "refrain from participating in practices or adopting dress that would make them appear different from the average citizen" (Smith).On a more positive note, as immigrants begin to live in America for a longer period, they are able to establish their own cultural identities and balance their two worlds. America does not discourage cultural diversity but embraces it. For example, the American education system has Spanish incorporated into its curriculum and bilingualism in the workplace is becoming a much sought after skill. There are numerous multi-cultural festivals in America, which aim to promote understanding between cultures. Immigrants have their own places of worship such as Mosques, temples, and community clubs in which they can socialize with other members who are sharing similar experiences. As time passes immigrants, do not isolate themselves from American life but become more involved. They are no longer lost tourists but real Americans who want to be involved in every aspect of American life, "Many are moving from a phase of dissociation from mainstream American life to much more active participation in political and social arenas" (Smith). Recent studies have found that the number of post-secondary degree presented to minorities has dramatically increased from 1991 to 2000. Degrees awarded to Hispanics and Asian Americans doubled while degree awarded to Indian Americans increased by 77%. All groups showed a large increase in the attainment of Masters Degrees and a slight increase in doctorate degrees. This increase is a clear indication that children of immigrants are working hard to close the educational and economic gaps between them and native-born Americans (American Council on Education, 2002). Although conditions are slowly improving, factors such as the language barrier and employment opportunities prevent new immigrants from enjoying the same privileges and benefits as those born in America. Unskilled workers who immigrate to America in hopes of finding a better life are often left disappointed. America does not have a huge shortage

Environmental Concerns Research Paper Example | Topics and Well Written Essays - 2500 words

Environmental Concerns - Research Paper Example The main consequences of global warming will be natural disasters like floods, famines, reduction in agricultural output, glacier melting, emergence of new diseases, extinction of species etc (Sinn, 2007). The consequences of the global warming are universally recognized and hence serious efforts are made by all nations to reduce the emission of greenhouse gases especially CO2.The main participants in these efforts are governments and people. In this essay, the public policy actions regarding global warming, the participants in the policy actions, the evaluation of policy, political concerns etc are critically analyzed. The excessive emission of greenhouse gases due to manmade activities can result in accumulation of heat in the earth’s atmosphere leading to a rise in global temperature. This phenomenon is called global warming (Cline, 1992). Among the greenhouse gases, all except methane are originated from manmade activities like fossil burning or electricity generation. Thus power plants are one of the main contributors of this phenomenon. The other main contributors of greenhouse gas emissions include deforestation, burning of gasoline in the engine of vehicles, use of fertilizers in agriculture, burning of organic matter, buildings that require lot of fuels etc. Due to the serious repercussions of the global warming problem concerning both developed and developing nations, it is widely recognized that an internationally integrated approach is needed to tackle this issue. The Kyoto Protocol based on the treaty on climate change in the United Nations Earth Summit in Rio de Janeiro,1992, c alled on both the developed and developing nations to formulate local initiatives to reduce the emission of greenhouse gases in all nations irrespective of the costs involved in these efforts(Hass et al, 1992). Both the governments and people can be the participants in the national and regional programmes in this regard. The historic treaty produced by the United

Interpersonal Management Skills Coursework Example | Topics and Well Written Essays - 1250 words

Interpersonal Management Skills - Coursework Example Leaders are expected to understand personalities of the people they lead. Interpersonal intelligence helps a person to deal with their emotions. It enables people to appreciate what they feel. Once a person is able to understand what s/he is going through, s/he is able to make wise decisions. Such a person will in turn appreciate others who are living around him or her. With interpersonal intelligence, one can understand other people and properly respond to their feelings. Responding to others needs is achieved when one fully understands their emotions (Fabian, Not dated). Self management skills enable a person to be positive about other people. In such a case, a leader will take time to address concerns of other people. A good leader will take time to inspire workers through encouragement. This promotes confidence of other people and boosts their morale. People with a proper interpersonal intelligence will relate with others showing a lot of understanding and concern. Management ski lls like these are important because managers encounter many people who have different expectations. Interpersonal intelligence helps a person to get along with others well during interaction. ... This ensures that people are able to live without commotion while they are living together in an organization. Attributes of a person are shaped by intelligence of people if they are able to deal with each other and to control their emotions. Behaviours of people are modulated by their better understanding of their inner feelings. Personal intelligence is manifested in the implementation of thoughts a person has about a situation or a condition. Managers should learn intrapersonal and interpersonal management skills so that they can choose the words they can speak to specified people. These skills are effective because they determine the choice of thoughts to release as actions or words (Fabian, Not dated). Statements from emotional intelligence intrapersonal intelligence that can reflect my strengths are: first, I have emotional resilience; this means that I withstand pressure and stress if they befall me, I regain my strength and continue with life. I am in full control of my feeli ngs. Second, I have personal power, and I am personally effective in control of my behaviour. Through this ability, I can choose what to do and when to do it. My behaviour is manageable because I have ability to avoid what I do not think worthwhile. The third statement of emotional intelligence intrapersonal intelligence I can say about myself is that I am flexible. This helps me to adapt to changes in the environment in which I live in. Sometimes these changes in the environment may not be predicted. This statement is a manifestation that I can respond to changes without struggling to make consultation. For example, at one time I am expected to perform roles as a mother of my children and at some other times I am supposed to behave as a wife to someone. These roles I manage because

Contents Contents 3 Introduction 4 Discussion 4 Background of Islamic Finance 4 Types of Contracts 6 Hedging Instruments of Islamic Finance 7 Profit Rate Swap 8 Foreign exchange Risk Hedging 9 Conclusion 10 11 References 12 Introduction Islamic Finance has been based on the principles of the Quran or more categorically on the principles of Sharia. According to the principles of Islamic Finance the acceptance and payment of interest is unfair. Thus Islamic Finance is devoid of any payment or receipt of interest in case of any business transaction. This kind of financing technique is adopted for the achievement of the goals which are specific to the Islamic economy. The sharing of the profit and loss is the main principle of the Islamic Sharia. According to the Sharia this measure would bring equity as well as justice in the economy. Hence the alternative names for the banks running on the principles of Islamic Finance are PLS bank. In the financial system there are various types of risks that persist which may result in a huge amount of loss. The hedging techniques are adopted in a financial market in order to cover a particular position of exposure which is generally in relation to a particular financial activity by taking a position that is opposite of what the risky situation is. Most of the banks take such hedging techniques in order to cover the exposures that arise out of the mismatches in the asset and liability of the books of accounts. These kinds of hedging techniques are also prevalent in the context of Islamic Finance. This essay looks into the various risk management measures that are being undertaken in order to provide a solution for the risk exposures and the types of instruments that are being implemented for the purpose. Discussion Background of Islamic Finance The main objectives of Islamic Finance are to promote the principles of Sharia in the ways in which business activities are being conducted. This is done with the objective of promoting growth and prosperity in the economy in a fair way. These financial services would conform to the principles of Sharia and would ensure that the distribution of income in the economy would be equitable and there would be optimal allocation of the resources in the economy in a justified manner. As opposed to the conventional modes of financing which considers interest as the opportunity cost of money, Islamic finance considers the existence of interest as an unjust practice. According to the principles of Islam, loans are provided by one party to the other to meet any kind of contingent situation that may arise. A lender should thus help the borrower to get the loan rather than taking undue advantage of it. Therefore there should be a relation of cooperation between the lender and the borrower. There is no relation of debtor and creditor as in case of commercial banking that is pr actice according to the general convention. The principles of Sharia state that there is simply no return that the people can actually reap unless they take any kind of risk. The principle in is practice in both the capital markets as well as the labour markets. This means that the labourers would not be eligible for wages unless they take some risks while working or bear a cost. On the other hand the capital

Encyclopedia Britannica Inc Essay By the time Britannica’s top management decided to stop producing bound sets of the iconic encyclopedia, the company had made sweeping changes to put itself at the forefront of the online education market. ne year ago, my announcement that Encyclopà ¦dia Britannica would cease producing bound volumes sent ripples through the media world. Despite the vast migration of information from ink and paper to bits and screens, it seemed remarkable that a set of books published for almost a quarter of a millennium would go out of print. But in our Chicago offices this wasn’t an occasion to mourn. In fact, our employees held a party the day of the announcement, celebrating the fact that Britannica was still a growing and viable company. They ate the print set—in the form of a cake that pictured the 32-volume, 129-pound encyclopedia. They displayed 244 silver balloons—one for each year the encyclopedia had been in print. They toasted the departure of an old friend with champagne and the dawning of a new era with determination. We had no need for a wake because we weren’t grieving. We had known for some time that this day was coming. Given how little revenue the print set generated, and given that we had long ago shifted to a digital-first editorial process, the bound volumes had become a distraction and a chore to put together. They could no longer hold the vast amount of information our March 2013 Harvard Business Review 2 This article is made available to you with compliments of Jorge Cauz. Further posting, copying or distributing is copyright infringement. How I Did It Britannica Then and Now customers demanded or be kept as up-todate as today’s users expect. The reaction to our announcement was interesting and varied. Some people were shocked. On Twitter, one person wrote, â€Å"I’m sorry I was unfaithful to you, Encyclopedia Britannica, Wikipedia was just there, and convenient, it meant nothing. Please, come back!† Of course, we didn’t need to come back, because we hadn’t gone away and weren’t about to. But although most people seemed to know what was happening, some misunderstood. Commentators intimated that we had â€Å"yielded† to the internet. In fact, the internet enabled us to reinvent ourselves and open new channels of business. Reports cited Wikipedia as a disruptive force. In fact, Wikipedia helped us sharpen our business strategy. Our content model was dismissed as â€Å"vintage,† but it is actually anything but: We update our content continually, with community input, reaching tens of millions of people every day—and they pay for it. I relished the irony. If you relied on free, gossipy online channels to understand why we were ending the print edition, you got what you paid for: some jokes, some inaccurate observations about the state of our business, and maybe a 20% chance of seeing â€Å"Encyclopà ¦dia Britannica† spelled correctly. You may not have learned that by the time we stopped publishing the print set, its sales represented only about 1% of our business, that we have an increasingly significant presence in the K–12 digital learning space, and that we’re as profitable now as we’ve ever been. Whatever ripples the announcement may have made, from a business perspective the decision itself was a nonevent. It was just the final phase of a carefully planned strategic transition that had been 35 years in the making.

Persuasive Easy Essay Gun Control seems to be on the top of today’s subject. After the recent tragedies that occur at Sandy Hook Elementary School in Connecticut, we are all concern for the victims. Many people are calling for stricter laws on gun control. No matter if you are for or against, something needs to be done about the regulation of gun control. In the past couple of years the United States has have its fair share of mass shooting form Congresswomen Gifford, Aurora, Colorado, and Jovan Belcher, a linebacker of the Kansas City Chiefs. He shot his girlfriend and then took his own life. In each of these events the guns used were legally purchased. Growing up with guns As a Native American and a member of the Jicarilla Apache Nation, we are tough about the proper handling of guns. As a young man I can remember going out to the gun rang with my grandfather and uncle. They would be teaching the safety of gun control. They would teach what was tough to be and would give lessons about what type of gun I would be using. Not only did I learn about what type of gun I was shooting, I also learned how to clean my gun. Learning the proper way of handling guns is important. The Jicarilla Apache Nation does a large amount of hunting for the people of the tribe. For some families this is the only way they, can receive meat. They also have rewards on some predator animals such as coyotes, mountain lions, and bears. Tribal members can go out to collect bounties on these predators. In one vehicle there could be as much as two rifles of one person. It is not uncommon to go to the local grocery store and see guns in people vehicles. No matter how many guns are around, gun violence is not the number one killer. The pros and Con’s about gun control. Many of the people want to band firearm. No matter if all firearms are banded many criminals could still get a gun. Marijuana is illegal to have in many states, but that does not stop people from getting the drug. Banding firearms is not the answer. It would make it harder for an honest person to obtain a firearm. Developing stricter background check can help in some cases. Teaching people the proper ways of handling a firearm could also help. Keeping them away from children and also teaching them about firearms is important. Many of the youth today carry some sort of firearms into school to show their friends. Both sides can debate the facts about the decrease or the increase of violence that a firearm could bring. The National Rifle Association (NRA) fights for the rights to use firearms for hunting and self defense. There are organizations that back up the rights for firearms. There are also many groups that are against firearms. Some facts about firearms and mass murders. Since 1982, about 61 mass murders were carrying out with the use of firearms in the United States. Within that about 49 for those murders are by firearms purchase legally. There are other counties were they have more firearms people. This does not mean that there are more shooting in those countries. The Second Amendment gives the right for an individual to possess a firearm. This Amendment was adopted into the Bill of Right in 1791. Since then time has changed and so should many of the laws. Having firearms to protect yourself and your family is important to most people, but there are other was to protect yourself and your family. A new study by Johns Hopkins researchers urging a tightening of gun control policies aims to inject some facts into what has become a highly polarized cultural debate while mass shootings and everyday gun violence claim thousands of lives in the USA (Devi, 2012). Conclusion If you are for or against firearms, the Second Amendment states that an individual has the right to bear arms to defend their selves and family form harm and danger. Having the proper education about firearms is important for each person who owns any type of firearms. Having a stricter background check can ensure that firearms are not sold to the wrong person. Despite all we can do if a criminal wants a firearm they could still receive one. Stricter laws about gun control can prevent some of the tragedies that have occurred in the United States.

Advantages And Disadvantages Of Remote Working System Computer Science Essay

Advantages And Disadvantages Of Remote Working System Computer Science Essay Introduction The following report will be based on providing potential requirements of the basic scenario and a through explanation of advantages and disadvantages of updating the current network of the EERP Company. By analysing the key requirements it is clearly explained that the EERP is having two major employee classes as senior staff and junior staff. Junior staff works in the office which mean that they worked on fixed places. This will result them to have personal computers with LAN (Local Area Network) connectivity. Depending on the budget this can vary up to a wireless network by implementing wireless interfacing cards to their personal computers and having WIFI zones on the working area. Senior staff on the other hand, they work in their homes. From their they should be able to do various kind of functionalities E.g. deliver companys message via ProwerPoint presentations, compile, print documents, perform quires on existing customer records, send and receive email and complete sales orders. These functionalities should be done online or through the WIFI network at the company. It is clarified that the management has decided to equip the senior staff with a mixture of wireless enabled portable notebook PCs, printers and Personal Digital Assistants (PDAs) to get the maximum benefits out of their senior staff. To achieve these desired functionalities it is a must to implement a Virtual Private Network (VPN) between the senior staff and the Office network of the office. This will result them to connect their office even though they are remotely connected. They will be able to perform same kind of functionality which they perform in their office environment. When they work in the office they can connect to the WIFI network without connecting to the VPN. This network architecture will provide the senior member to be connected on their office network every time whenever they want. When it comes to wireless connectivity or VPN, security is a must. It is important to implement necessary security methods and protocols to connect any of the networks. With respect to the following requirements no of WIFI and VPN users should me defined and should be expandable with the growth of the company. Depending on the budget, suitable VPN provider should be selected. With the basic understanding of the key requirements it will be possible to prepare a network system with remote networking functionality. Advantages and Disadvantages of having remote working system Pros, It will be easier to implement and maintain. High reliability and availability. Network cabling will be reduced. Employees can stand on their work place dynamically without staying on one location Can easily configure the security of the network. Can easily divide departments as blocks of network access points. Expansion of the network will be easier than a Traditional wired LAN. Cons, Network connectivity will be lower than a wired LAN. VPN implementation will be expensive. Company should be facing a higher security threat when implementing a VPN. In order to enhance the security, firewalls and other third party tools have to be purchased. Employees should be well trained to use VPNs and wireless networks to avoid any sort of interruptions. Failure of a VPN will result some employees to not to cooperate with the company until it is fixed. Benefits to the company This system will allow employees to work interactively without any disruption. Employees who work on the office will have the WIFI connectivity. This means that they can work on their office desk as well as when they are not. They might be interacting with the customers even so they can connect with the network. They can share information, print documents and can query the information database. This will result interactive and efficient communication with their customers. Senior staff on the other hand can work in home as they are in the office. Because of the VPN they will gain almost all of the network capabilities as they are in the office. Email services, document sharing, print documents and even online presentation facilities can be provided. When they visit the office they can connect to the wireless network using their wireless enabled notebooks and PDAs. As a result they can have almost the same functionalities.

A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISPs network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet. When data is sent between locations on one network or from one network to a second network the data is always seen and directed to the correct location by the router. The router accomplishes this by using headers and forwarding tables to determine the best path for forwarding the data packets, and they also use protocols such as ICMP to communicate with each other and configure the best route between any two hosts. Network Interfacing Card A network interface card, more commonly referred to as a NIC, is a device that allows computers to be joined together in a LAN, or local area network. Networked computers communicate with each other using a given protocol or agreed-upon language for transmitting data packets between the different machines, known as nodes. The network interface card acts as the liaison for the machine to both send and receive data on the LAN. The most common language or protocol for LANs is Ethernet, sometimes referred to as IEEE 802.3. A lesser-used protocol is Token Ring. When building a LAN, a network interface card must be installed in each computer on the network and all NICs in the network must be of the same architecture. For example, all must either be Ethernet cards, Token Ring cards, or an alternate technology. WIFI Cards A wireless network adapter allows a computing device to join a wireless LAN. Wireless network adapters contain a built-in radio transmitter and receiver. Each adapter supports one or more of the 802.11a, 802.11b, or 802.11g Wi-Fi standards. Wireless network adapters also exist in several different form factors. Traditional PCIwireless adapters are add-in cards designed for installation inside a desktop computer having a PCI bus. USB wireless adapters connect to the external USB port of a computer. Finally, so-called PC Card or PCMCIA wireless adapters insert into a narrow open bay on a notebook computer. One example of a PC Card wireless adapter, the Linksys WPC54G (compare prices) is shown above. Each type of wireless network adapter is small, generally less than 6 inches (0.15 m) long. Each provides equivalent wireless capability according to the Wi-Fi standard it supports. Some notebook computers are now manufactured with bulit-in wireless networking. Small chips inside the computer provide the equivalent functions of a network adapter. These computers obviously do not require separate installation of a separate wireless network adapter. Setting up wireless Connectivity I have used TP_LINK as the router. To connect to the router I have used on of the LAN ports. At the browser type http://192.168.1.1/ to view the login page.

Bob Marley Essay -- Art

Bob Marley Clemson University There are hundreds of thousands of people screaming for you on stage. The Prime Minister and leader of the opposition sit in the arena. Many thought this was a sight that would never be seen, but it was just the sight Bob Marley had in front of him at the One Love Peace Concert in Kingston Jamaica (April, 1978). This was his first appearance back in Jamaica in 14 years, an amazing show culminating with Bob joining the hands of opposing political figures onstage, and holding them firmly together. A hero and an icon while living, Bob Marley continues to influence people 25 years after his death (African Service News). His music and lyrics worked as the rhetoric of the Rastafarian movement against oppression, exploitation and racism in Jamaica. Using metaphors to describe the hardships of the political fights of Jamaicans and Africans Marley established himself as the spokesman of a race and culture. The Rastafari religion, the heart of Bob’s music, based itself in belief of ‘Jah,’ which was a metaphor for a god of goodness and love. Jah was the force fighting against the oppression from ‘Babylon,’ the destructive force. Metaphors of oppression and freedom, such as chains and birds, depict social problems and ways of liberation (Jensen). Many of Marley’s lyrics included these references and therefore fell into the latitude of acceptance, explained in Muzafer Sherif’s studies on Social Judgment Theory (Griffin), of his Rastafari listeners. When Marley spoke of things that were in the latitude of acceptance of his audience, his words impacted them listeners incredibly. â€Å"If you get down and quarrel everyday/You're saying prayers to the devil, I say/ Why not help one another on the way/ Make it much easier/ Jah love, Jah love, protect us† Positive Vibrations. Marley strived to increase awareness among the people of Jamaica, but his popularity didn’t end there. His music spread through the hearts of Europeans, Africans, and Americans. Lyrics and music work together to offer messages comprised of both theoretical and emotional content through the constructs of virtual experience (lyrics) and virtual time (music). Both virtual experience and virtual time must exist for music to function rhetorically (Sellnow). However it can sometimes work out otherwise. In fact, it was the bass heavy style of Bob Marley’s new age r... ... when it hits you feel no pain.

Exploring Classical Theism and Physicalism :: Religion

Exploring Classical Theism and Physicalism ABSTRACT: Could a classical theist be a physicalist? Although a negative answer to this question may seem obvious, it turns out that a case can be made for the consistency of a variant of classical theism and global supervenience physicalism. Although intriguing, the case ultimately fails due to the weakness of global supervenience as an account of the dependence of mental on physical properties. Physicalism is popular these days, and to a lesser extent so is classical theism. It should therefore come as no surprise that a number of theists are bent on combining theism with physicalism. But could a classical theist be a physicalist? Is this a coherent doctrinal combination? The classical theist affirms the metaphysically necessary existence of a concrete, purely spiritual, being upon which every other concrete being is ontologically dependent. The physicalist, however, is committed to the proposition that everything, or at least everything concrete, is either physical or determined by the physical. To be a bit more precise, physicalism is usefully viewed as the conjunction of an 'inventory thesis' which specifies physicalistically admissible individuals and a 'determination thesis' which specifies physicalistically admissible properties.(1) What the inventory thesis says, at a first approximation, is that every concretum is either a physical item or composed of physical items . As for the determination thesis, what it says is that physical property-instantiations determine all other property-instantiations; equivalently, every nonphysical property-instantiation supervenes on physical property-instantiations. These rough characterizations suggest that theism and physicalism logically exclude one another. If God as classically conceived exists, then the inventory thesis is violated: not every concrete entity is either physical or composed of physical items. And if God exists, it would also appear that the determination thesis is flouted: God's instantiation of his omni-attributes does not supervene on His instantiation of any physical properties: He has none. So at first glance it seems almost crashingly obvious that the classical theist cannot be a physicalist. But this talk cannot end just yet. For when we get down to the details of formulating precise versions of both the inventory and determination theses, it turns out that there is a way to attempt the reconciliation of theism and physicalism. It is the viability of this way that I aim to explore. But first some background. Towards Nonreductive Physicalism I will take it for granted that a plausible version of physicalism cannot be either eliminativist or reductionist.

Salaries of Athletes are too High Essays -- Professional Athlete Athle

Salaries of Athletes What should athletes deserve to be paid? Many players have risen to stardom by becoming a professional athlete. Athletes have come from many different backgrounds; some from wealthy and some from poverty raised backgrounds. Salaries are continuing to rise, and money doesn’t seem to be an issue. Athletes are getting what they want from the owners by negotiating through their agents. Athletes’ salaries aren’t from their owners, but they come from other sources (â€Å"Athletes’ Salary†). Athletes get paid an extremely high salary for the work they do, and should consider the value of their work. They do not deserve the extreme amount they get paid and something should by done about it. One issue that these high salaries cause is that having all this money spoils the athletes. Athletes buy so much unnecessary stuff after they get their money. For example, Michael Jordan has about 28 cars. Who needs all these cars? He didn’t buy all of these, but there is a certain limit on how many cars a person needs. Athletes spend their money on cars, entertainment, clothes, and their big mansions. Another instance of athletes spoiling themselves is the use of illegal drugs (â€Å"Pro Salaries†). Michael Irvin of the Dallas Cowboys has been involved in many of these altercations. He has been through all the punishments there possibly is and still makes his money (â€Å"Pro Salaries†). Athletes think they are at a higher level and that they can do whatever they want. An issue that everyone hears about everyday that a pro athlete has committed a murder/crime. Ray Lewis, a safety for the Baltimore Ravens, is being tried for two accounts of murder. He is an excellent athlete. He is on the pro-bowl team for the 1999 season and led the league in tackles. He has just ruined his career by even being involved in a situation like this. Another player is Robert Lewis, a 20 year-old basketball player from the Dallas Mavericks. He was convicted of beating his girlfriend almost to death. A 20-year-old basketball star doesn’t need to feel that he is a king to be a leader. What kind of role model is he setting to other youngsters that want to follow in the same footsteps? The salaries of athletes are extremely high for the effort that they put through. For example, basketball, baseball, and hockey athletes only compete for about 6-8 months a year. Then they have... ...r salaries are too high to compare. They do entertain the public, but the expense for the entertainment is too steep. Athletes should make a decent salary, but they should have control over their limits. They deserve a salary that would compare to other officials who are more important to the people and that have a role which effects the people as a whole. Something must be done before a drastic change occurs. Bibliography: â€Å"Athletes’ Salary.† CQ Researcher. 2000.

Most of them are easily prepared in ethereal solution (usually diethyl ether or, since the early 1950s, THF) by the reaction of an organic halide with metallic magnesium (eq 1).Table 1.

The importance of this contribution to synthetic chemistry was recognized very early, and for his discovery Grignard was awarded a Nobel Prize in Chemistry in 1912. Our cover molecule is the monomeric ethylmagnesium bromide bis(diethyl etherate) (1), whose solid-state molecular structure was determined by an X-ray diffraction study by Lloyd Guggenberger and RobertRundle in 1964 using crystals isolated from a diethyl ether solution of a C2H5Br/Mg reaction mixture by slow cooling with a stream of cold gaseous nitrogen. 2-4 Adapted from: Schlenk, W. , Jr. Ber. Dtsch. Chem. Ges. 1931, 64, 734. Wilhelm Schlenk and his son discovered 80 years ago, more than one magnesium-containing species exists in the diethyl ether solution of a Grignard reagent. 5 A redistribution of the substituents on magnesium takes place, and the RMgX species ends up in equilibrium with the two symmetrical species, the diorganomagnesium and the magnesium dihalide: the â€Å"Schlenk Equilibrium† (eq 2). 2RMgX h R2Mg + MgX2 (2) Generally written as â€Å"RMgX† in textbooks, monographs and research papers, the Grignard reagents in ethereal solution are more complicated than this simple formula indicates.

Ges. 1908, 41, 2244. The oxonium structure The species that contain Mg-halogen bonds can be precipitated from Grignard reagent solutions in diethyl ether by the addition of 1,4-dioxane. An insoluble, polymeric 1,4-dioxane adduct is formed, leaving behind a solution of R2Mg5sa useful preparation of dialkyl- and diarylmagnesium reagents. 6 Wilhelm Schlenk, Jr. analyzed the 1,4-dioxane precipitations from a number of Grignard reagent solutions. Assuming that the precipitation is essentially instantaneous, i. e. , that the calculated R2Mg, MgX2, and RMgX percentages re? ect the actual composition of the Grignard reagent solution at equilibrium, Schlenk reported the compositions collected in Table 1. Direct evidence (5) Schlenk, W. ; Schlenk, W. , Jr. Ber. Dtsch. Chem. Ges. 1929, 62, 920. (6) (a) Cope, A. C. J. Am. Chem. Soc. 1935, 57, 2238. (b) As Erwin Weiss found, evaporation of diethyl ether solutions of methyl- and ethylmagnesium bromide and chl oride at reduced pressure followed by heating of the colorless solid residues at ca. 00  °C and 0. 001 mmHg for several hours gave a mixture of the respective pure, solvent-free, polymeric R2Mg compounds and magnesium halides. The solid MgCl2 thus obtained differed from a sample obtained from a MgCl2 melt in that its lattice showed a strong stacking disorder. This form of MgCl2 had an extremely high surface area: Weiss, E. Chem. Ber. 1965, 98, 2805. (7) Schlenk, W. , Jr. Ber. Dtsch. Chem. Ges. 1931, 64, 734 Further additions to the examples in Table 1 were soon thereafter reported by other workers: (a) Noller, C.

Earlier workers had isolated noncrystalline solid samples of etherates, e. g. , C2H5MgI  · (C2H5)2O and RMgI  · 2(C2H5)2O. (4) Other early Grignard reagent crystal structur es: (a) Stucky, G.

Am. Chem. Soc. 1969, 91, 3847. ). that solutions of â€Å"CH3MgBr† in diethyl ether contain CH3MgBr and (CH3)2Mg was obtained by Ashby and co-workers by means of 1H NMR spectroscopic measurements at -105  °C. Solutions of â€Å"t-butylmagnesium chloride† in diethyl ether also were studied. 8 The tendency of the halide substituents in the RMgX and MgX2 species present in ethereal solution at equilibrium to form bridges between magnesium atoms, Mg-X-Mg, in a Lewis base/Lewis acid type interaction further complicates the nature of the Grignard reagent in ethereal solvents.In a very thorough study of the association factors of various Grignard reagents in diethyl ether and THF by careful ebullioscopic molecular weight measurements, Eugene Ashby and Frank Walker at the Georgia Institute of Technology found that monomeric, dimeric, and higher oligomeric species were present, depending on the solvent and the halogen and the organic substituents on the magnesium atom. 9 Included in this study along with data for the â€Å"RMgX† solutions were data for a few R2Mg compounds and for the magnesium dihalides.As Figure 1 shows, the observed association factor (the i value is the apparent molecular weight divided by the formula weight of the monoetherate) shows that the Grignard reagents and (C6H5)2Mg are close to monomeric in the relatively strong Lewis basic THF. The picture is quite different in diethyl ether solution (Figures 2 and 3), with association factors of 1 to nearly 4 for solute concentrations up to ca. 3 molal. It is not clear what these i values mean in terms of the a ctual species present in these solutions.On the assumption that the Schlenk equilibrium is operative in all cases, in view of the presence of a signi? cant concentration of MgX2, one cannot expect only simple solvated species of type i(R)Mg-X] n [ i (average n ) i). Toney and Stucky isolated crystals of a dimeric species, 2, from a solution of â€Å"C2H5MgBr† in di-n-butyl ether by addition of this solution to triethylamine. 10 The molecular Figure 2.

This compound was not a simple Cl-bridged dimer, as the empirical formula might suggest. Actually, it was a tetramer (Figure 4) in which the Mg atoms have a coordination number greater than 4. 1 There is a caveat, however: the species t hat crystallizes from a Grignard reagent solution does not necessarily directly re? ect what species are swimming around in the solution. The crystalline solid shown in Figure 4 could well have self-assembled during the crystallization process by combination of two molecules of the C2H5Mg2Cl3 dimer and not been present in solution at all. Even in the case of monomeric â€Å"RMgX† in THF solution, the Schlenk equilibrium will be operative and the strongly Lewis basic THF apparently prevents halide bridging between Mg atoms.Consequently, the (10) Toney, J. ; Stucky, G.

Molecular structure of [C2H5Mg2Cl3(C4H8O)3]2, a tetrameric Grignard reagent. Modi? ed from Toney and Stucky (J. Organomet. Chem. 1971, 28, 15. (copyright 1971, with permission from Elsevier)). presence of monomeric RMgX, R2Mg, and MgX2, all solvated, would resu lt in the measurement of an association factor of 1, as Walker and Ashby observed.There are so many factors that bear on the question of the constitution of a given Grignard reagent in ethereal solutionsthe Lewis basicity and steric properties of the ether solvent, the electronegativity and size of the halogen atom in RMgX, the nature and steric properties of the organic substituent on the magnesium atom. These will affect the magnitude of the equilibrium constant of the Schlenk equilibrium and the extent of Mg-X-Mg bridging. For most applications in synthetic chemistry it will suf? ce to take the easy way outsto regard and to write the Grignard reagent as RMgX.There is another interesting and useful property of ethereal Grignard reagent solutions. The magnesium species are weak electrolytes in such solvents of low dielectric constant, and â€Å"RMgX† solutions conduct an electric current. 12 The electrolysis of solutions of organomagnesium halides was studied in some detail by Kondyrew at the State Research Institute in Leningrad13 and by Ward Evans and his students at Northwestern University. 14 During the electrolysis, magnesium species migrate both to the cathode and to the anode. Scheme 1 shows the simplest picture based on RMgX. Metallic magnesium is formed at the cathode. 12) The earliest report appears to be a 1912 French paper: Jolibois, P. Compt. rend. Hebd. Seances Acad. Sci. 1912, 155, 213. See also: Nelson, ? J. M. ; Evans, W. V. J. Am. Chem. Soc. 1917, 39, 82. (13) (a) Kondyrew, N. W. Ber. Dtsch. Chem. Ges. 1925, 58, 459. (b) Kondyrew, N.

(14) The Evans group published many papers in J. Am. Chem. Soc. during the 1933-1942 period. See, for example: (a) Evans, W. V. ; Lee, F.H. J. Am. Chem. Soc. 1934, 56, 654. (b) Evans, W. V. ; Field, E. J. Am. Chem. Soc . 1936, 58, 720. (c) Evans, W. V. ; Braithwaite, D. J. Am. Chem. Soc. 1939, 61, 898. (d) Evans, W. V. ; Braithwaite, D. ; Field, E. J. Am. Chem. Soc. 1940, 62, 534.

The alkyl radicals formed at the anode can undergo the usual alkyl radical processes of coupling (to R-R), disproportionation (to RH + R(-H)), or, if the anode is composed of a reactive metal such as zinc, aluminum, cadmium, or lead, they can attack the anode to form an organometallic compound.A graduate student of Evans, David G. Braithwaite, joined the Nalco Chemical Co. after he graduated and developed an electrolytic process for the commercialscale syntheses of tetramethyl- and tetraethyllead antiknock agents in which the respective alkyl Grignard reagents were electrolyzed in a mixed THF/diethylene glycol dimethyl ether solvent system using a lead anode and a steel cathode. 15 The reactions of the Grignard reagents with organic, organometallic, and ino rganic substrates and their applications are too numerous and varied to be covered here.Not only do they ? nd extensive use on a small to moderate scale in research laboratories but they also have been prepared and utilized on a large scale in diverse industrial processes. For the most part they react as nucleophilic reagents, as would be expected, on the basis of the polarity of the carbon-magnesium bond, C? –Mg? +. However, they also can undergo electron transfer reactions with appropriate electron-acceptor substrates. They are weak bases capable of deprotonating the stronger weak organic acids such as terminal acetylenes and cyclopentadiene.Their basicity can be enhanced (as can be the basicity of organolithium reagents) by the addition to RMgX solutions in ethers of additives such as hexamethylphosphoric triamide (HMPA) and N-methyl-2-pyrrolidinone (NMP) or alkali-metal alkoxides. All such information can be found in books devoted solely or in part to Grignard reagents. 1 6 Two special topics are of current interest and merit special mention. (1) The preparation of highly functionalized organomagnesium reagents by Paul Knochel and his co-workers at the University of Munich17 by means of halogen-magnesium exchange (e. . , eq 3). The availability of reagents such as 3-8 (which must be utilized at low temperature) has added a new and spectacular dimension to Grignard reagent chemistry. (2) The synthesis of ole? ns, styrenes, 1,3-dienes and biaryl derivatives by the crosscoupling of Grignard reagents with organic halides. The crosscoupling of Grignard reagents with vinylic halides was discovered by Morris Kharasch and Charles Fuchs at the University of Chicago Organometallics, Vol. 28, No. 6, 2009 1601 Table 2.Transition Metal Halide Catalyzed Homocoupling of Phenylmagnesium Iodidea metal halide FeCl2 CoBr2 NiBr2 RuCl3 RhCl3 PdCl2 OsCl3 IrCl3 a amt, mol 0. 01 0. 01 0. 03 0. 0036 0. 0036 0. 00566 0. 00275 0. 003 amt of C6H5MgI, mol 0. 03 0. 03 0. 095 0. 0 108 0. 013 0. 0163 0. 007 0. 01 yield of biphenyl, % 98 98 100 99 97. 5 98 53 28 Taken from: J. Am. Chem. Soc. 1939, 61, 957. in 1943 during the classic studies of Kharasch on the chemistry of Grignard reagents in the presence of transition-metal halides. 6b Kharasch and Fuchs found that arylmagnesium bromides in diethyl ether reacted readily with vinylic halides of type RCHdCHX and R2CdCHX (but not CH2dC(R)X) to give styrenes in 50-75% yield when the reactions were carried out in the presence of 5 mol % of CoCl2 (eq 4). 18It was reported that other metal halides (of iron, nickel, and chromium) also were effective catalysts of this cross-coupling reaction. Benzylmagnesium chloride also reacted in this manner with vinyl bromide to give PhCH2CHdCH2 in 75% yield.Alkylmagnesium halides such as cyclohexyl- and n-butylmagnesium bromide, on the other hand, gave only â€Å"small to negligible† yields of the expected coupling product. The ArMgBrderived biaryl usually was obtained as a byproduct in these reactions. Such homocoupling of arylmagnesium halides in the presence of a transition metal halide as well as copper and silver halides was a known reaction. It had been investigated in 1939 by Gilman and Lichtenwalter, who found that aryl Grignard reagents undergo homocoupling in the presence of ca. 0 mol % of various transition-metal halides in diethyl ether solution to give the respective biaryl in high yield in most cases (eq 5, Table 2). 19 The metal halide, in addition to being the needed catalyst precursor, also served as an oxidizing agent and, in some cases (CoBr2, NiCl2, RhCl3), formation of a black solid indicated complete reduction to the metal. not occur in the absence of the organic halide but in its presence was vigorously exothermic. The added organic halide was only partially consumed and did not show up in the biaryl product.When p-bromotoluene was added to a phenylmagnesium bromide/CoCl2 catalyst reaction mixture, only biphenyl was formed. A re markable reaction! smost likely a free radical process, as Kharasch suggested. The organic halide was believed to function as an oxidizing agent. This interesting, simple, and potentially useful cross-coupling reaction, as exempli? ed in eq 4, was not adopted by the synthetic organic community right away. After a long dormancy it was rediscovered some 30 years later by a number of groups in the USA, Japan, and France, all of whom apparently were not aware of the 1943 Kharasch/Fuchs JACS paper. 1 Transition-metal catalysts other than CoCl2 were used, but the concept and the basic reaction were the same. In 1971 Tamura and Kochi reported a thorough study of the cross-coupling of Grignard reagents with vinylic halides catalyzed by soluble iron species in concentrations of ca. 10-4 M in THF at 0-25  °C. 26,27 Various Fe(III) compounds could be used as Fe catalyst precursors; the best were Fe(III) -diketonates such as Fe(RC(O)CHC(O)R)3 (R ) Ph, CH3, t-Bu). These exothermic reactions we re not free radical processes. The reactions of cis- and trans-propenyl bromide proceeded with retention of geometric con? uration (eqs 6 and 7) and were not adversely affected by the presence of 0. 4 M styrene.

The results of a few experiments carried out on a 30-40 mmol scale (Table 3) showed that such iron-catalyzed reactions would be useful in the synthesis of ole? ns, but a broader study to optimize them and to broaden the scope of their application was not undertaken.

A similar Grignard reagent based cross-coupling, ole? n synthesis in which a copper(I) catalyst was used was published by French workers. 9 Normant et al. reported that their reactions (e. g. , n-Bu(Et)CdCHI + i-PrMgCl in THF at -20  °C with a Cu(I) catalyst) proceeded with retention of con? guration. 29a For a reaction of CH3CHdC(CH3)MgCl with n-C3H7I in THF at 0  °C using CuI as catalyst, Linstrumelle reported that the coupling product obtained in 97% yield was 88% cis and 12% trans, while a similar reaction of CH2dC(CH3)MgBr with trans-n-C6H13CHdCHI gave a 4:1 trans/cis product. 29b TheuseofNi(II)catalystprecursorsforGrignardreagent-vinylic halide cross-coupling was reported in 1972 by Corriu and Masse30 and by Tamao, Sumitani, and Kumada. 1 The French group found Ni(II) acetylacetonate to be the most effective catalyst precursor, while the Japanese group favored a bis(tertiary phosphine)NiCl2 catalyst precursor and, especially, chelating diphosphine complexes such as (Ph2PCH2CH2PPh2)NiCl2. Reactions carried out in diethyl ether at re? ux generally gave excellent yields.

(c) Historical note: ref 23. ith vinylic and aryl halides, that catalyzed by palladium complexes, was reported by Shun-Ichi Murahashi and coworkers in 1975. 33a The reactions were carried out in diethyl ether/benzene at room temperature using (Ph3P)4Pd as the catalyst precursor, and they proceeded stereospeci? cally in excellent yield (Scheme 2). Dang and Linstrumelle also used this procedure to prepare 1,3-dienes stereospeci? cally by the reaction of vinylic iodides with vinylic Grignard reagents. 34 Palladium-catalyzed cross-coupling of Grignard reagents with organic halides has been a very active area in organic synthesis.Reference 25 reviews (up to 2002) its application in (alkenyl) MgX-ArX, ArMgX-(alkenyl)X, and (alkenyl)MgX-(alkenyl)X coupling processes. A further chapter in this book deals with ArMgX-Ar? X coupling. 35 Another surge of research activity on cross-coupling of Grignard reagents with organic halides started around the turn of the century and still appears to be in progress at the present time (January 2009). Interest has revived in the use of iron complexes as precatalysts for the cross- and homocoupling of Grignard reagents,36 since iron complexes are cheaper than those of palladium and are nontoxic.The iron-catalyzed cross-coupling of organomagnesium bromides with vinylic bromides, although it produced ole? ns in good yield, was of interest to Jay Kochi, as noted above, primarily from the point of view of its reaction mechanism rather than of its potential for application in organic synthesis. After some 25 years several research groups carried out much experimental work which has shown iron-c atalyzed cross-coupling and homocoupling of Grignard reagents to be broadly applicable and very useful additions to the methods of organic synthesis.In 1995 Gerard Cahiez, at the Universite Pierre et Marie Curie ? ? in Paris, during the course of his extensive investigations of organomanganese chemistry, found that the cross-coupling of vinylic bromides with alkyl, vinylic, and phenylmanganese chlorides could be effected in good yield in the presence of 3 mol % of iron(III) acetylacetonate in a THF/N-methyl-2pyrrolidinone (NMP) mixed solvent at room temperature. 37 In a thorough study, this reaction was extended to the crosscoupling of vinylic halides with alkylmagnesium halides using 1 mol % of Fe(acac)3 and the same solvent mixture. 8 High yields of ole? nic products were obtained. Successful crosscoupling of Grignard reagents with AcO(CH2)6CHdCHCl, CH3C(O)(CH2)3CHdCHCl, Cl(CH2)4CBrdCH2, 9, and 10 are noteworthy as examples of the selectivity and functional group tolerance of this reaction. The scope of this chemistry was extended further when some of Knochel’s functionally substituted aryl Grignard reagents17 (vide supra) were reacted with vinylic bromides and iodides. 39 The cross-coupling reaction between aryl Grignard reagents and vinylic bromides and iodides also was found by Cahiez and co-workers to give ole? ic products in good yield with Organometallics, Vol. 28, No. 6, 2009 1603 Table 4.

On the other hand, such reactions do occur in the presence of an iron precatalyst and various additives (eq 8, R? ) alkyl), as summarized in ref 36. A number of other groups have reported the results of their research directed toward development of an effective procedure for the process shown in eq 8, all using an iron precatalyst of one kind or another, various additives such as TMEDA, NMP, etc. nd generally diethyl ether (but sometimes THF) as solvent. 41 It is noteworthy that primary and secondary alkyl halides, i. e. , ones that contain hydrogen substituents on the carbon atom, can be cross-coupled with aryl Grignard reagents, a process that cannot be realized using (34) Dang, H. P. ; Linstrumelle, G. Tetrahedron Lett. 1978, 191. (35) Anastasia, L. ; Negishi, E. -i. Chapter II. 2. 5, pp 311-344, in ref 25. (To date palladium and nickel catalysts have been widely used to effect aryl-aryl cross-coupling reactions. However, arylmagnesium halides were found to undergo cross-coupling with aryl halides that contain electron-withdrawing activating substituents ortho or para with respect to the halogen substituent in the presence of 10 mol % of manganese(II) chloride (eq 10). 44 Cyclohexyl and 2-methylpropenyl Grignard reagents reacted with such substituted halobenzenes in a similar manner.

In one example, chlorobenzene (1. 0 equiv) and p-CH3C6H4MgBr (1. 2 equiv) were added to this catalyst system and the reaction mixture was stirred at 60  °C for 1 day. The desired product, p -CH3C6H4-C6H5, was obtained in 98% yield. The homocoupling product, biphenyl, was present only in trace amount, while CH3C6H4C6H4CH3 was formed in 3% yield. Some examples of the application of this remarkable reaction are shown in Table 4. Good results were obtained only with aryl chlorides.Aryl bromides and iodides gave low biaryl yields. A German group reported similar MnCl2-catalyzed cross-coupling between various heterocyclic chlorides and aryl as well as alkyl Grignard reagents: e. g. , eq 11. 46 a Taken from: J. Am. Chem. Soc. 2007, 129, 13788. The homocoupling reaction of aryl Grignard reagents, mentioned earlier, also has received renewed attention recently, and synthetically useful procedures have resulted. Nagano and Hayashi developed a procedure in which the reaction is carried out in re? uxing diethyl ether in the presence of 1-5 mol % of FeCl3, NMP and 1. molar equiv of 1,2-dichloroethane (which serves as the oxidant). 47 Cahiez and co-workers have improved this procedu re by using THF as solvent, in which arylmagnesium halides, including the chlorides, are more easily prepared. 48 This procedure works well with Knochel’s functional arylmagnesium halides (Scheme 3). Of interest also is the clever construction of the tricyclic system 11 by intramolecular homocoupling (Scheme 4). (40) (a) Cahiez, G. ; Gager, O. ; Lecomte, F. Org. Lett. 2008, 10, 5255.

Scheme 3 special, but generally applicable, reaction conditions developed by Japanese workers45 have ? nally prov ided the possibility of clean aryl-aryl cross-coupling reactions in which competitive homocoupling of the aryl Grignard reagent has been almost completely suppressed.In this procedure an active catalyst system was prepared by addition of 18 mol % of C2H5MgBr in Organometallics, Vol. 28, No. 6, 2009 1605 A further improvement resulted when it was found that atmospheric oxygen could replace the 1,2-dihaloethane as oxidant in the homocoupling of aryl, vinylic, and alkynyl Grignard reagents using either Fe or Mn catalyst precursors. 49 As Tables 5 and 6 show, this procedure gave excellent results. The most recent contribution to iron-catalyzed cross-coupling, which appeared during the preparation of the ? al draft of this paper, involves application of the old one-pot Barbier procedure in which FeCl3 served as precatalyst and stoichiometric amounts of magnesium turnings and TMEDA additive were used. A mixture of an alkyl and an aryl bromide was added to the mixture of precatalyst, TMEDA , magnesium, and solvent at 0  °C. Good yields of cross-coupled products were obtained. 50 There has been a great deal of activity in the areas of Grignard reagent/organic halide cross-coupling and aryl Grignard reagent homocoupling, and the coverage in this essay, whose focus is on the historical aspects, is far from exhaustive.Attention is called to the 2005 review by Frisch and Beller51 and especially (49) Cahiez, G. ; Moyeux, A. ; Buendia, J. ; Duplais, C.

There is much more about Grign ard reagents that I have not covered: the various procedures used in their preparation, the mechanism of their formation (which is still controversial), the more complex organomagnesium compounds such as bis(cyclopentadienyl)magnesium, magnesium butadiene, and magnesium anthracene, and the many kinds of reactions that Grignard reagents have been reported to undergo.But this is only a short essay, and so I have been able to cover only a few selected topics, ones which I hope will be of interest to the reader. More information can be found in the books that I have cited earlier. 16 Acknowledgment. My thanks, as always, to Professor Arnold L. Rheingold for the cover ? gure. OM900088Z (52) Acc. Chem.
