Gender differences in the effects of divorce Essay

Besides behaviour differences among children of divorced and intact families, there are also gender differences to consider. Hyatt suggests that boys and girls react differently to parental divorce. Boys tend to create more behavioural problems in school than girls do. Boys’ self-esteem tends to decline as a result of divorce and they seek constant attention from the teacher and disturb class with irrelevant talks. Their effort in school work also decline. Hyatt mentions that boys are more prone to difficulty of losing contact to their father hence regular communication with the father can help these adjustment problems. Girls’ behaviour in school after parental divorce is not as noticeable as boys because they do not manifest their difficulties by acting out in class. Rather, they tend to become more anxious or unhappy or showing over controlled good behaviour. Another findings concerning gender difference in the effects of divorce is that girls do accept help from their teachers unlike boys. This is because girls see their school as a place where they can be supported during divorce while boys conduct socially unacceptable behaviour. School Behaviour of Children of Divorced Families Human beings grow by constantly adapting to new environment therefore adapting to an environment is part of life cycle. Children’s educational place can be divided into home, school and the society. The child and environment continuously interact and the school takes over large part of a child’s life. Therefore as well as having a settled family life, school period is also important in determining how children might turn out in the future. School is a place where children enjoy, and gain sense of satisfaction by experiencing various activities and maintain harmonized relationships with the teachers and other students. Similarly, school adjustment is defines as taking interest in school environment and feel comfortable being in school with other children. This adjustment reflects on their school achievement and development. For instance, children who enjoy being in school and participate in school activities are likely to gain more educational experiences than those who have adjustment disorder. Liebman defines school adjustment disorder as excessive reaction where individuals are unable to harmonize with the school environment and other students which will prohibit individual development. Children of divorced families are likely to have more difficulties in school adjustment than those of children from intact families. Berbe suggests that children with adjustment disorder tend to attract teacher’s attention by inappropriate questions in class, distract other children and find it hard to pay attention in class. They also refuse teacher’s request and are often disobedient. And if they continue to show irresponsible academic behaviour, it leads to serious adjustment disorder. Heck’s idea is also similar to Berbe’s suggestion that children with adjustment disorder problems are frequently absent and tend to be oppositional in class. However, it is difficult to judge the cause of maladjustment solely on divorce. How children respond to above stress can vary from a child to child. It can differ according to their age, gender or disposition and the environment includes economic stature of parents, social approval rating of parents and family conflict. Variables are categorized as they may affect children’s school adjustment into demographic differences and family variables. Demographic differences include race, gender, and parental socioeconomic status and family variables include relationships, organisation, control, social support, mother rejection and father rejection. Behaviour of children of divorced in school As mentioned earlier, children from divorced families appear to have difficulty in academic achievement and relationship with other children at school than children from intact families. The cause of this should not be looked at solely on the primary factor which is divorce. Secondary factors are to be considered as well, such as the change in socioeconomic structure and resources after divorce. For example, as mentioned earlier, economic loss, poor parental adjustment, lack of parental competence and parental loss can cause behavioural problems. As mentioned in the section of ‘Comparison between children of divorce and intact families’, women’s standard of living is reduced by 29 % after divorce and absence of father can have negative influence on children more on boys than girls. Regarding studies on children’s maladjustment behaviour, Liner categorizes disorder behaviour as: ? action-out behaviour like hitting someone and being aggressive ? withdrawing behaviour: very quiet, sucking fingers, restricted behaviour ? defensive behaviour: lying, ignoring ? disorganised behaviour: escaping from reality Similarly, Wickman describes behaviour of children with adjustment disorder as: ? immoral, dishonest, in resistance to authority, stealer, cheater, disobedient, rude and rebellious ? often violates regulation of class, careless, loses interest in study, negligent and trustless ? exaggerated and offensive personality ? unsociable, overly sensitive, and liar Based on experience, as a teacher of young children, those from divorced families have lower academic achievement, are socially isolated, overly sensitive, either humiliate themselves or boast and show negative behaviour in class. Specifically, their academic grade is poorer than it used to be and they do not try to socialize with others in class. Further, they often seem absent-minded and tend to change their mood easily. If they are scolded for not doing their homework or asked to answer something they do not know, they use violent language in response. They also suffer from headache and easily get tired. This behaviour of children can also be explained by Rotter’s theory of locus of control. Locus of control refers to how individuals attribute the cause of their behaviour to internal or external forces. In applying to children of divorced families, children who have internal locus of control believe that if their parents are divorced, it is their fate. Therefore these children are able to handle any difficulties and feel less psychological distress. In contrast, children who have external locus of control believe that if they do not perform well in school, they tend to blame external factors such as parental divorce rather than blame themselves. Hence, these children are likely to suffer from severe distress than those who have internal locus of control. When elementary school children experience parents’ divorce, they can become aggressive and develop sense fear and sorrow. Some children also imagine reunion of their parents. And they also explain that children’s school behaviour depend on how they are treated at home. As per experience, the relationship between custodial parent and the child seem to have a large impact. Prior research says that the relationship between the behaviour of custodial parents and children’s school adjustment illustrate that the attitude of custodial parents has large influence on children’s school achievement. Mothers’ affection can influence enormously on developing children’s social skills. From mother-child relationship, children learn responsibility, self-control and social skills, hence, hostile attitude towards children can act as hindrance in developing social skills. Therefore one can learn that the attitude of custodial parent becomes important factor which influence children’s school adjustment.

Leadership Analysis

Running head: SCHOLARSHIP, PRACTICE, AND LEADERSHIP Scholarship, Practice, and Leadership Essay Cory A. Muhammad University of Phoenix Education and Information Literacy In a US society where information literacy is considered a luxury and not a human right enables intellectual illiteracy limits to be pushed to the max. It’s a nightmare how some can be deceived and taken advantage of or even locked out of opportunities by those who demonstrate the use of information literacy. The desire for current and upcoming generations desiring access to information through text is becoming scarce. Researchers found that current and possible future generations would rather watch videos or tutorials instead of reading information found in text materials. â€Å"Experts suggested that they preferred to view information rather than read it, and so tended to choose information that was graphically represented rather than just text-based† (Venkatraman, 2009, p. 6). Today within the environment of education we are experiencing an increasing need for individuals to take interests in their own learning and exposure to information literacy for a variety of reasons: a) It gives learners the ability to become exposed to higher education and technology b) Enables learners to communicate (using technology) in an educational setting, and c) Prepares students to relate to the various generations of learners. In this essay I will discuss how information literacy relates to the scholar/practitioner/leadership model. Higher Education and Technology Anyone pursuing higher education will have to get use to the ideal of incorporating scholar practice of information literacy. As learners grow stronger in the use of information literacy, we can expose ourselves to higher educational opportunities such as Universities, trade colleges, skill centers, or career enhancement programs. Once an individual can be exposed to the various information located in most libraries all information retrieved completely enhances all researched subjects and allows for more profound subject content. In higher education information literacy plays a major role in the use of technology. Technology is an essential learning tool used amongst students and professionals today. Information illiteracy can lead to the mis-understanding and fear of technology. Information illiteracy can ultimately cause generational gaps in communication as-well. When one generation has not adequately prepared for the trend of another generation (generation X) vs. (Generation Y), this is a clear indication of information illiteracy. The new generation communicates in an integrated way, leveraging the technology that’s available. However libraries and other information providers â€Å"have fundamental problems in adapting†, â€Å"They're not keeping up with the demand of these researchers, who live in the wider internet space,† (Venkatraman, 2009, p. 6). Education and Communication Using Technology Computer literacy, Internet literacy, e-mail functionality, search engine and database li teracy are a few amongst a huge arena of technology functions in our ever changing world we live in. Information literacy allows learners the opportunity to become literate in the world of technology and the use of wonderful tools to gain better performance in processing day to day tasks. The flipside to this same coin is information illiteracy prevents people from knowing about the reality of technology and its benefit. Information literacy ultimately improves the learner’s quality of life as they are being exposed to superior methods of functioning, as well as make themselves marketable from possessing education. â€Å"Most are not even aware of the potential help that is available to them. Libraries, which provide the best access point to information for most U. S. citizens, are left untapped by those who most need help to improve their quality of life† (â€Å"Association of College & Research Libraries,† 1989). Communication Channels to Transcend Generations Information literacy ensures opportunity for open communication channels between different generations of learners, or leadership teams. Adequate communications through information literacy develops leadership amongst the educational atmosphere. The one who has the ability to relate to the various generations can easily emerge from the groups as a leader. Learning and professional environments benefit a great deal when an open line of communications exists between generations incorporating, wisdom, knowledge, desire, energy, and perspective. Information literacy allows for generations to be aware of each others benefit, but also rely on each other for constant innovation and progress. Information illiteracy will only promote detraction from any information or understanding of various generations and a low desire for people to pursue higher education. â€Å"There is a danger of a new elite developing in our country: the information elite† (Venkatraman, 2009, p. 6). Information literacy on the other hand, promotes the desire of individuals to continue to pursuing knowledge, and learning. In conclusion, the articles researched on information literacy revealed the current condition in our country regarding information illiteracy. Grades K-12, secondary, post secondary, graduate and even doctoral learning suffers from information il literacy. Students not engaging in intense research fail to use credible sources that handicap their ability to broaden their knowledge on specific subject matter. Students’ abilities to incorporate diverse forms of information literacy will enhance their educational experience and make it a more lifelong and fulfilling learning experience. By restructuring the learning process learners can develop skills to become practitioners of information literacy. Information literacy helps set up various frameworks for individuals to resolve moral dilemmas. The continued development of information literacy models could provide students and professionals within organizations the relatable life skills required for the scholar/practitioner/leadership model.

Change

Have you ever wondered what it would be like to switch places with your mom? Or what losing your job would be like? In the summer of 2014 I faced both of these problems. I had just started caddying and was not looking forward to it but, I had just my parents saw it as more than a jobit was a learning experience. I would do anything to avoid going to work even when my parents encouraged me. As an only child my parents always put me first but, when one of them needed me I put everything aside because family comes first. In 2014 my mom fell from a 20 foot ladder. She broke her pelvis and shattered her wrist from the impact of the fall. She was put into a hospital and needed to get surgery for both of her injuries. My dad stayed with her for as long as he could but had to work so I took care of my mom. I had to go to the hospital two times a day to check in on her and see if she needed anything. The situation was very awkward for me because for the first time my mom and I had switched roles. At the time I was happy to take care of my mom because it was an excuse for me not to go to work. For my job you have to be in the top 100 in order to come back the next year. In the back of my head I knew that I was not going to make that because of the situation I had on my hands. After the year had ended I had found out I didnt take the top 100. My parents were disappointed that I did not make the list but where more proud that I had helped my mom when she needed it. The next year my mom talked to my boss and told him why I didnt make the list. He was very understanding and gave me my job back. The next summer when I got back to work I was extremely motivated to make my parents proud and succeed in my job. I worked hard the entire year finished in the top 100 and even received a promotion. As a kid, I didnt realize how important it was tohave a flexible well paying job. My parents always set me up for success and when I was little I was not able to recognize that. By putting everything aside during the situation I was able to learn valuable life lessons along with important things about myself. I learned that no matter what happens in life family always come first and that you never know how someone feels until you walk in their shoes. I took for granted what my mom had always done for me because I thought it was just what she was supposed to do. After I took care of her for that summer I realized how hard she worked to suit my every need no matter how hard the task. I learned that I am hardworking and when I put my mind to something im devoted to do it to the best of my a bilities. The situation helped me to evolve into the person that I have become and at the same time show me that family is the most important thing in life. Spending the time with my parents during a time of hardship brought us closer then we had ever been. I was able to make them proud because of my actions regarding the accident and how I bounced back in life stronger than ever. Not only did I learn things about myself but my family learned that no matter the situation we can always count on one another.

Strategicmanagement Essay Example | Topics and Well Written Essays - 1000 words

Strategicmanagement - Essay Example Its overall performance has been consistently very good and it is moving in the right direction by seeking advice as regards specific strategies and long term objectives in the current market scenario. Nonetheless, in spite of its stellar performance and status, CGC must steadily adapt to the current business practice of path-breaking forays that among things include globalization, mergers and acquisitions, joint ventures, and excursions into unexplored regions notably the Middle East, South Asia and South-East Asia. The economical growth and social progress in these regions, despite their vicissitudes, uncertainties and filibustering elements provide the right environment and prospects for games like golf. Also, CGC must widen its range of product. Big players like Nike and Adidas have entered the golf market. It is time CGC made forays into some products manufactured and marketed by Nike, Adidas, etc, that are not currently in the list of products covered by CGC. Golf has fairly good presence in countries like China, Korea, and India. The game has attracted enough attention at elite business and social levels for formation of golf clubs which include acquisition of large tracts of land even in cities like Mumbai (Bombay) where real estate prices are among the highest in the world. GGC has encountered piracy problems in China, and undoubtedly the p... n at elite business and social levels for formation of golf clubs which include acquisition of large tracts of land even in cities like Mumbai (Bombay) where real estate prices are among the highest in the world. GGC has encountered piracy problems in China, and undoubtedly the problem does not exist in China alone. Apart from taking legal steps, there is the need to address the problem more pragmatically by entering the market through the front door in these regions. China and India have opened up to foreign investments like never before. The best way to begin operations is by getting hold of big names like Kapil Dev to endorse CGC products. Kapil Dev is a former cricketer and has tremendous fan following in India. Apart from Kapil Dev, there are other players, both current and retired, who play golf. Cost of Endorsements Getting big names like Kapil Dev to endorse is expensive. Conservatively, the price could be around US$ 10 million for five years. This is a rough estimate. Other Costs Other costs include sponsorship of golf events and players. It is difficult to provide precise figures. However, CWC could mark their presence with a budget of another US 6 million dollars for 3 years. It will be necessary to appoint an official representative who is conversant with golf to act on behalf of CGC. The annual cost for such a representative will be US$ 250,000 annually to cover salary, house rent and travel. Annual Budget Thus, the total annual budget will be as follows: 1) Endorsement by a big player US$ 2,000,000 2) Sponsorship of events and players US$ 2,000,000 3) Official Representative's salary, rent, travel US$ 250,000 4) Other promotional costs US$ 250,000 Total Cost US$ 4,500,000 Agenda for Return on Investments (ROI) It is not

Translating Project Management Knowledge to Project Programs Research Proposal

Translating Project Management Knowledge to Project Programs - Research Proposal Example Project managers have to find ways by which they can manage this knowledge that is in the hands of their employees. They should come up with ways that this knowledge is focused on the enhancement of the project. Management of knowledge to help it in the reasoning processes and making an important decision in an organization is called knowledge management. For knowledge to be effectively managed in an organization, special tools must be employed to do this. The knowledge base is a special kind of database for knowledge management (Jacobsson, 2011). During knowledge management, data is collected, then into information, shared, then easily searched and used. For data to be more reasonable to an organization, it requires to be converted to a better version for the organization. When data is well organized and utilized, it can enable an organization to make good future decisions affecting the organization. As an organization transforms data to wisdom, understanding also increases; now dat a is well organized and can be used directly by an Organization in decision making. The organization processes, policies, and procedures are clearer, more complete, more correct and more concise when data is organized. There is an increase in the levels of innovation. A lot of new products and services are offered to consumers in the market. Project managers must understand this and employ strategies that make innovation a core factor of their businesses (Clarke, 2010). Innovation enables the projects to be what is desirable to users and come up with what is convenient for them. Marketing should be given a key role in any project. Without effective marketing, the details of the project remain within the team. This does not add any value to the team.

International Conflict Resolution Research Paper

International Conflict Resolution - Research Paper Example Ethnic conflict threatened the territorial integrity of countries throughout the world including Somalia, Rwanda, Sierra Leone, the Democratic Republic of Congo, and Liberia in Africa; Bosnia and Kosovo in Eastern Europe; state-sponsored ethnic cleansing in East Timor in Asia and extreme violence on the North American island nation of Haiti. Although ethnic conflict and humanitarian crises have existed since the dawn of time, for the first time ever images of extreme bloodshed, violence, and even genocide were broadcast into the homes of everyday Americans through international television stations like the Cable News Network (CNN), Fox and the British Broadcasting Corporation (BBC). Despite shocking violence perpetrated by a variety of militia forces in the Western African countries of Sierra Leone and Liberia, the international community, by and large, stood still while extreme violence and crimes against humanity were carried out with seeming impunity. While it is evident that conflict has been endemic in the modern post-Cold War world, how has conflict been resolved in recent times? There are a variety of theories to international conflict resolution including peacebuilding, peacekeeping, and Alternative Dispute Resolution. This essay will discuss each theoretical paradigm and will persuasively show that peacebuilding and peacekeeping go hand in hand and that they are the most viable means through which global conflict can be managed and averted. We will explore the case of Sierra Leone and argue that it emphatically demonstrates that international actors must work to maintain the peace in societies which have experienced incredible violence and social collapse and that both peacekeeping and peacebuilding must take place in order to heal old wounds and ensure that conflict does not reemerge. Alternative Dispute Resolution is a third-party resolution process whereby mediation is undertaken by an external party to help resolve the c onflict.

Models of Criminal Justice System in England and Wales Essay

Models of Criminal Justice System in England and Wales - Essay Example These delegate the Police with the responsibility of the control of crime (Lea 2002, pp.32,67); the Prison Service, to run prisons; the Probation Service with the role of rehabilitation; the Crown Prosecution Service, for bringing action against those suspected of committing a crime; the Magistrates' Courts and the Crown Court with the responsibility of dealing with the trial of suspected criminals; the Court of Appeals for the final conviction of the perceived criminal; the Prison Service, for running prisons; the Serious Fraud Office for the investigation of frauds and other similar offences that affect trade the corporate world (Davies, Croall & Tyrer, 1995, pp.274, 342, 121, 152, 156, 274, 133). A new CJS agency in England and Wales took effect in 2001. The new Criminal Defence Service was established by the Access to Justice Act of 1999 which also established a Legal Services Commission which supervises this new agency (Wheeler 2006,p.165). This provides state-employed defence counsel that serves as lawyer to indigent defendants (Hirschel et al 2007,p.176). The CJS in England and Wales is essentially rooted in three principles. The first is that an accused is presumed to be innocent until proven guilty by proof beyond reasonable doubt. The second is that the criminal justice system is basically adversarial in nature i.e. that the accused is aided in his defence by a counsel while a prosecutor tries to prove that he is guilty and both parties face each other in court as adversaries (Davies, Croall & Tyrer 1995, p.193). The third principle states that there is criminal liability only when there exists in the actor

Making financial decision based on financial decision Essay

Making financial decision based on financial decision - Essay Example Cash budget would allow the owner to analyse how much the company is earning and the investment and cash disbursement for the project. Cash disbursement is the outflows of cash. Cash receipts are the inflows of cash. The first investment opportunity that the company has is Quad Bikes. The ticket price for Quad Bikes has already been estimated by the owners and it is equal to $15. The cash budget for Quad Bikes showing the cash recipients and cash disbursement is as follows: The ticket price for Paint Ball has been estimated by the management of Hall Hill Farm and the price is expected to be $13. Using this price and other costs that have been estimated, the cash budget for the company for Paint Ball would be: The other major project and investment opportunity that the Farm has is to invest in Fish Hatchery which the management has been planning for some time. The price for fish hatchery has not been estimated by the management, however to prepare a cash budget the price is estimated to be $12. Using the price $12 for each of the visitor for fish hatchery, the cash budget would be: At the moment, the cash position of the Hall Hill Farm is unfavourable. Therefore it is important for the farm to analyse the loopholes in the cost structure and come up with strategies that could improve the current position. After analysing the cash budget of the company, it has been analysed that most of the costs of the company is the fixed cost and these costs are to be paid regardless of the earnings of the company. Therefore it is important for firm to expand its services and facilities so that more visitors are attracted and the revenue can be increased. One of the recommendations to improve the current cash position of the farm is to rent retailers outlets and shops at the farm. This would allow the farm to improve its revenues, as the farm has substantial space vacant. Besides allowing

Issues in International trade Essay Example | Topics and Well Written Essays - 1250 words

Issues in International trade - Essay Example They include consultancy and tourism among others. A product sold in the international market is an export while a product bought from the same market is an import. Trade issues often dominate and are a continuing theme in the international market. The issues include NAFTA, embargoes, sanctions, and the environment, trade deficits, The Euro, tariffs and WTO among others. Some of the issues are discussed as follows: A reduction in trade barriers allowing for integrated global economies and permitting international trade will affect the environment through the expansion of economic activities. It alters the composition and make-up of economic activity by bringing about a change in the techniques and means of production. The course of consideration and for environmental protection was raised by environmental groups on the potential North American Free Trade Agreement (NAFTA). This was just the first of a far cry to other voices opposing international or regional trade on the possible effects it may have on the environment. It is seen that an increase in international trade is detrimental to the objective of preserving a clean, healthy and sustainable global environment. It has been argued that any expansion of market to a global scale, ultimately leads to the environmental pollution and faster depletion of natural resources. These natural resources are scarce in nature. For example, international trade of coal has made it easier for countries to acquire it for economic activities. Coal has been known as a leading environmental pollutant. International trade has facilitated the growth of industries whose primary objective is the export of goods to the international market. For example, the United States has promoted several of such agreements such as the African Growth and Opportunity Act (AGOA) and the NAFTA. These agreements have led to the rapid growth of industries that have little government oversight and control. These

Women Prisons Before the 1800 Essay Example for Free

Women Prisons Before the 1800 Essay â€Å"Women were punished as men were, with the exception that pregnant women were often spared punishment until after they had given birth. Women were generally mixed with male prisoners and supervised by male jailers, which made the women doubly subject to abuse and exploitation.†(Foster, 2006) Women who violated the law, then, also violated their subservient position and were seen as morally suspect as well as criminal. Prior to the development of prisons in the seventeenth and eighteenth centuries, punishment for women and men took a variety of forms: Serious offenders were put to death by hanging or burning, or banished from their community or sold as slaves How have they changed? The Indiana State Reformatory was established in 1873 as the first separate prison for women in America. (Foster, 2006) The women in prisons are still treated the same except they have separate prisons and more rights to help them when they are abused. They still do have coed prisons in Illinois but they are minimum security prisons. What are the three basic arguments established in the 1800s that supported the separation of juvenile prisoners from adult prisoners? 1. The penitentiary regimen was too hard on tender youth. 2. Juveniles would learn bad habits from older criminals and be embittered by The experience of confinement. 3. Adolescents could be reformed if they were diverted early enough into institutions Designed specifically for people their age. What would happen if there were no distinction between prisons for juveniles and adults? It would be like sending flocks of young sheep to live with older wolves. The juveniles would be exploited and exposed to a great deal immoral and illegal things. What was the purpose of prison labor? In the 1800s, prisons recouped their expenses by leasing convicts to private companies; in 1885, fully three-quarters of prisoners were involved in some form of labor, mostly for private companies or individuals (du Pont, Some Benefits of Prisoner Labor). This had little to do with attempts at  rehabilitation. Prisoners were forced to work without pay, often in dangerous conditions; convict miners were killed in cave-ins in the 1800s (Leonhardt A1). In 1887, Congress for the first time attempted to outlaw the leasing of convict labor to private parties (Ingley 28+), but there was backlash at the state level: refusal to house federal prisoners. What finally drove legislation restricting prison labor were the Depression and the increasing fear that private jobs would be lost to cheaper convict labor. The 1935 Hawes-Cooper Act, along with the Ashurst-Sumner Act of 1940, outlawed interstate trade in convict-made goods, making it a felony and a federal crime to traffic in them (OMeara 14; du Pont, Some Benefits of Prisoner Labor). Subsection (b) of the Ashurst-Sumner Act does exempt goods made in State prisons for use by any prison in any other state, or federal prison-made goods for use by any other federal prison (Ingley 28+). Congress banned prison labor use on federal contracts exceeding $10,000 the same year (du Pont, Some Benefits); the Walsh-Healey Public Contracts Act placed limits on the purchase of prison-made goods by the federal government (Ingley 28+).

A history of drumming

A history of drumming Drumming is a great way to express emotions in a musical form. Over the years drumming has changed a lot, from using just a log to using a full drum set full of different types. Many forms have come into style over the years from jazz drumming to metal-core drumming. Drumming has changed over the years from its equipment to the styles people now use. Drumming is one of the most primitive ways to create music and it has been around for eons ever since man could hold a stick he has been hitting it against some other object. The Africans have been using drumming for a long and they still use today just for about everything, it is used for ceremonies and some even use for finding food. Back in the revolutionary war drums where used to help the soldiers walk in time for when they where marching it was also used in combat to help them over come the fear these where know as war drums. Eventually man started to use drums with other instruments to come up with more types of music such as Jazz, Swing and some of the more modern rock and blues all use drums. Over the years there have been many famous people in the drumming industry from all types of music. Some great examples are Danny Carey, Jimmy Cobb, Blake Richardson and one of these drummer are well know for there bands there in and the styles they have developed over the years of play ing drums. Now Danny Carey is from the band called Tool and is know for is very off the wall random timing drumming which is very hard for other drummers to follow when they listen to his music. His style is so hard to follow because he doesnt have a set timing he goes by he just throws his sounds in where he thinks they would sound the best and that is what makes him and his band so unique from other bands. Jimmy Cobb is from the thirties and he is known for being one of the most famous jazz drummers he is mainly a self taught drummer and in know for one of the most famous jazz songs called Kind of Blue. He has played at many famous places but the one that he played in the made his so famous was Carnegie Hall. Now North Carolina is know for a lot of things but with todays music one of the more famous drummers to come out of these hill is Blake Richardson who plays with the band Between the Buried and Me. Blake and his band are known for the more progressive style of music and Blake style is all of his own in 2008 he was voted the worlds third best drummer. (History of Drumming) A style that has become more noticeable is metal-core drumming. Metal drumming is a very misunderstood style of drumming. Some think that it is comprised of just random beats that are just thrown together; but it is actually a pretty technical form of drumming. It contains some very complex rolls and fills that require the player to be focused at all times. Metal drumming originated from both the swing and jazz style of drumming, which are some of the earliest forms of drumming. Most, if not all, metal drummers train in some version of jazz and swing style when taking lessons. Metal has always incorporated jazz and swing to help them become great drummers. Jazz helps by adding more fluidity to drumming, while swing helps with speed, precision, and foot speed. (Healthy Drumming) Metal drumming has proven to be one of the more difficult forms of drumming, because of the speed required. In addition, this style of drumming has some of the more complicated beats. Some famous drummers in the metal world is Blake Richardson from the band Between the Buried and Me, Danny Carey from Tool, and Matt Greiner from August Burns Red. Each of these drummers all have their own unique playing styles, which they have developed over many years of playing the drums. Blake Richardson took many drum lessons which included jazz and swing he says Jazz and Swing are vital to any drummer if they want to become a great drummer, it helps you in many ways it helps improve your stamina do to the constant playing at a fast tempo. (Healthy Drumming) Swing drumming is a very important drum style mainly because the music is quite fast, and the beats are complex. Swing goes by many names: swing jazz, swing music, and just swing. It has been around since the 1930s it was a new upbeat version of jazz that was created so that the music could keep up with the new faster moving dances and around 1935, it had made come into its own distinctive style. Swing drumming used a lot of a technique called double bass, which helps drummers pick up the pace of a song more quickly. The double bass is where the bass drum has to kick pedals connected together so that both feet can kick the bass drum and make it sound like the drummer is playing faster. Once swing drummers incorporated double bass, the sound to make their music have more of brutal of a sound. (Healthy Drumming) The equipment for drumming has evolved greatly since its inception millions of years ago. When man first started drumming, the set up consisted of a hollow log and a medium sized stick; in contrast, todays drum set is more sophisticated. For example, cymbals made a great improvement in the sound of music with its ability to help a drummer to keep the timing of a song. When drummers buy cymbals, they have to take in how much splash or crash they want. Splash cymbals vary in sizes from six to twelve inches. The splash is often a syncopated accent to the drum. These cymbals are often hit very hard so they had to make them a little thicker. However, this thickness can cut down on the richness of the sound that they produce. Splash is a nice little cymbal to add to a drum kit because the sound it produces can add to any genre of music, not just metal or jazz. Then there are crash cymbals which are used of occasional accents and they usually add a sharp sound to the song. The term crash wa s first used by the company Zildjian who has making cymbals for over 40 years. Crash Cymbals can be mounted on a stand and played with a stick or they can be played with mallets to give them a slower sound and a more swelling crash. (Rhythmic Power) Bass drums are another crucial part to drumming, because it adds a backbone to the song itself. In other words, it gives the beat a deeper sound. Swing utilizes the bass drum very well. Originally the bass drum was help keep timing so the drummer would not kick all that quickly they kept it to a 4/4 beat a 4/4 beat is a technique that all musicians use to mark the tempo of the song. But in Swing there was the creation of the double bass pedal which allowed drummers to create an even faster beat and let them use the bass drum in different ways from keeping time to rolling on it to add the sound. There are a majority of different types of pedals, ranging from titanium pedals and aluminum pedals, to coil pedals and chain pedals. Iron Cobra is one of the more common of the pedal distributors and there latest pedal The Iron Cobra power glide double pedal uses a coil under the pedal itself to add to the power of the pedal and it also cuts down on how much energy the player uses. (Rhythmic Power) Snare drums play an even larger role in drumming than any of there other pieces I just listed mainly because it is one the first pieces ever made. The Snare drum was created originally for combat for soldiers to use on there way to battler back during the revolutionary war. Now the snare is used for all kinds of music related things it is used a lot in drum line it is the focus piece in drum line. In drum line there is usually three snare drum players that lead the rest of the line and if they get off beat even for a moment then they through the rest of the line off rhythm. Snares are usually one type of sound but some come with a dampener on them which release the springs that are attached to the bottom of the snare and when they are released it give the drum amore bass sound. There are assortment stands that can come with the snare some are made for standing up and some made for knee height when the player is sitting down. There is also the synthesized snare drum which is a pad tha t is connected to a small computer that has a large number of sounds built into its database. This snare is used as a side snare so that the drummer can use a normal snare and then this snare to give there sound a more distinct sound from other drummers. (Rhythmic Power) In conclusion drumming has been around for many years and it has been changed about every year it has been around. The equipment has changed in many different ways over the years they have been made more modern from there original forms. Forms of drumming has changed just as much as the equipment changing from just beats people put together to more distinct styles such as jazz, swing and metal. And the history for drumming is very vast since it is one of the precursors of music. Work Cited The Recorded History of Jazz Drumming. Public domain. Web. 29 Oct. 2009. .

Jazz :: essays research papers

The conceptual idea of humanism has existed since before the years of Christ. Biblical records state that when man was created he was made in the image of God. This image has been passed down throughout the civilizations of Greece ,Egypt, and Roman times and it has been passed down to our civilization of today. The evidence of this is in the art of yesterday and the way we view art of today. The way we view art today is in such a way that we feel and conceptualize what we create. We create things in the image of how we view our life, our civilization, and our status in this civilization. In applying the things stated in the previous thought to the human life the result will be art . Culture is a distinct component of what society is. Culture is in all essence what culture does. The whole purpose of culture is to in a way define a specific race or creed. Culture is what makes us unique and very individual. An example of this is myself and my cousin named Brandon. We are both in the same family and we both have been raised with the same values but what makes us different is the culture we have adopted in our lives to help us define the way we feel about ourselves and the way we feel about society. I feel as if the afro-American race is moving in a progressive manner towards unity and he feels as if the Afro-American race as a whole is moving towards separation by the complexion of their skin. The culture that I have adopted has shaped my views and ideas and the culture he has adopted has shaped his thoughts and ideas. My ideas are not better than his nor are his better than mine ,just different. Civilization is defined as many things but you can only define what is civil for your own civilization. Many people have a definition of what a civilization is but when they make this definition it is by their own standards which is wrong. A civilization is a place or group of people who can defend themselves from enemies, get or create a quantity of food, establish a currency, and develop a trade with others. In America we view life as a sacred and very precious thing . In other countries death is viewed as the

The Broken Heart of Sylvia Plath Essay -- Biography Biographies Essays

The Broken Heart of Sylvia Plath "Dying is an art, like everything else. I do it exceptionally well." Sylvia Plath has long been recognized as a poetic icon. After committing suicide in her thirties, many of her previously unrecognized works gained notoriety and praise. Throughout her life, she struggled to be accepted into the literary world. After writing many poems, short stories and "The Bell Jar," she remained unsatisfied with the success and momentum she gained with each, and took her own life. It is through her words we see a woman that used her writing as a means of expression, many times expressing grief, sadness and anger. Plath began writing a series of poems shortly before her death that provide is with an opportunity to see the internal conflicts she felt. Many of these poems focus on death and suffering. Plath uses death imagery in poems found in Ariel to represent her need to escape reality and therefore dissociate herself from emotional and physical existence. I will show how Plath's life experiences and more importantly, her reactions to them, have contri buted to her depressive, death-obsessed state. I will also provide examples from several of her poems demonstrating Plath's use of death imagery and analyze why it is used in the way that it is. Lastly, I will show how many of her poems from Ariel demonstrate Plath's self-loathing, and her need to feel a sense of success-even if that success comes from an accomplished suicide. Although Sylvia Plath had many opportunities throughout her life, and accomplished what many only dream of, we see how the few tragedies she did endure, affected her. At age eight her father died from complications related to diabetes. Plath had been very c... ...g and gruesome at times, but each tells a story-a story of a woman, her life, her struggles, her successes and her failures. All of them allow us to step into the broken mind and heart of Sylvia Plath. Works Cited Broe, Mary Lynn. Protean Poetics: The Poetry of Sylvia Plath. Columbia: U of Missouri P, 1980.

No-calorie Powder May Substitute For Foods Fat :: essays research papers

No-Calorie Powder May Substitute for Food's Fat George E. Inglett of the U.S. Department of Agriculture's Biopolymer Research Unit in Peoria III invented a no-calorie fat substitute called Z-Trim. It is a mix of crushed fibers made from the hulls of grains. It can replace the fat and some of the carbohydrates in foods such as chocolates, brownies, cheese, and ground beef. He spent three years trying to perfect Z-Trim to be smooth because he made it out of tough hulls of corn, oats, and rice. He first crushed the hulls with a solution of hydrogen peroxide. He washed the peroxide off in centrifuge. After this step it was still too large, so he put the pieces back through the first step of the hydrogen peroxide and the centrifuge. That made it smooth. Now, it is a fine, white cellulose powder that can be made into a gel by adding water. Inglett also developed Oatrim. This is made up of a digestible fiber from oat flour that provides four calories per gram. Z-Trim compared to another fat substitute, olestra, is different. Olestra can cause gastrointestinal distress and take vitamins and carotenoids out of the body. The new substitute does not have those affects. Inglett says that you should eat more of the kind of fibers that make up Z-Trim to reduce the chances of getting intestinal disorders. But there are some people who argue with Inglett's theory on his new substitute. "I wouldn't expect Z-Trim to have the same kinds of problems as olestra," says Margo Wootan, a senior scientist at the Center for Science in the Public Interest in Washington, D.C. "Fiber is already found in our diet, while olestra is a synthetic chemical. There is also concern for the "microbial stability" of foods containing Z-Trim. "Whenever you remove the lipid material and replace it with water," says Thomas H.

Sexual Ethics Essay

1. There are a number of dilemmas in sexual ethics such as homosexuality, marriage and divorce and pornography. For instance homosexuality is a major problem within sexual ethics because homosexual sex cannot lead to reproduction. However sexual ethic it differs between denominations compared to government law. Therefore these issues are a concern to religious belief; different faiths have different view on homosexuality or marriage and divorce.Many religious beliefs do not encourage homosexuality in fact it is severely discouraged for example in the Islamic faith they do not allow this because there is no doubt that in Islam homosexuality is considered ‘sinful'. Homosexuality as far as Islam is concerned is a profound mistake (as are all sins if they are not intending to do wrong). For instance a quote from the Qur’an says â€Å"What! Of all creatures do ye come unto the males, and leave the wives your Lord created for you? Nay, but ye are forward folk. † Qur'an 26:165.The references relate to gay sexual activities; lesbian practices are not mentioned in the Qur'an, neither is it mentioned in the bible. Christians are divided over the issue of homosexuality. Due to natural law homosexual sex cannot lead to reproduction therefore the marriage would be considered invalid, however then a marriage between an older couple or couples who infertile would also be invalid, therefore all homosexual acts and relationships are sinful so many believe homosexuality is contrary to God’s will.However the Roman Catholic Church teaches that homosexual should be treated with respect, compassion and sensitivity and no discrimination, they believe the feeling aren’t wrong but the actions are sinful because they contrary to the will of God. The scriptures of the bible suggest that the only sexual relationship that God approves of is one between married heterosexual partners. The creation narrative describe woman as being created especially for man: â€Å"a helpful suitable for him† (genesis 2:18). The Old Testament said â€Å"If a man lies with a man as one does with a woman, both of them have done what is detestable.They must be put to death† (Leviticus 20:13) however there is still no mention on lesbian practices. Marriage is an important part of the Christian life a the purpose of Christian marriage is faithfulness to one another, many Christians teach than within marriage there is a natural hierarchy that reflects the relationship of Christ and the church. The Roman Catholic Church says â€Å"wives, in the same way be submissive to your husband†¦ Husband, in the same way be considerate as you live with your wives, and treat them with respect† (1 peter 3:1, 7).Whereas the Church of England argues that the relationship is based upon Christ’s headship over the church and is about love and sacrifice, not domination and power. This argument originally started as the bible said â€Å"a man will leave his father and mother and be united to his wife and they will become one flesh† (genesis 2:24). On the other hand, in the Islamic faith marriage is only a way to make sex and having children legal and lawful, the belief also states in the eyes of Allah both members of the relationship are treated equally even though they have separate duties. Whereas the Christian views on divorce are that marriage is for life.People take vows for better or worse so if they meant that then there should be no divorce. For instance the Roman Catholic Church believe there shouldn’t be any divorce unless the marriage has not been consummated or they are willing to get a divorce with the permission from the pope. Whereas the Church of England except divorce but some more traditional vicars don’t allowed divorces to remarry in church, the bible believes divorce is not favoured by God: â€Å"Therefore what God has joined together, let man not separate (Matthew 19:6) which means God joins them so the law cannot separate them.Even Jesus forbids divorce: â€Å"Anyone who divorces his wife and marries another woman commits adultery. And if she divorces her husband and marries another man, she commits adultery† (Mark 10:11-12) However in Matthews gospel it say â€Å"anyone who divorces his wife, except for marital unfaithfulness, and marries another woman commits adultery† (Matthew 19:9). Alternatively divorce in Islam is only when the male partner says Talaq 3 times can divorce the couple, however this banned in some countries which results in going to arbitration council and judicial intervention before the divorce is granted. . Due to the loss of faith in many denomination and cultures today, we as people no longer look to religion to guide our sexual ethics as we once did. It is no longer relevant because many people believe that anymore should be able to marry anyone they want, for example same-sex partners. The debate is still being waged be tween the church and government to offer this union. Many people believe if two people are happy together and want to join themselves in holy matrimony, then they should be allowed.Marriage has also undergone many changes as people are less likely to have a â€Å"traditional† wedding instead they are more likely to enjoy extended co-habitation. Also the concept of marriage has change because it is more of a legal act rather than a declaration of love to God. Whereas divorce is seen by the eyes of most people is all about the law rather than church. Church seems to have very little authority when a marriage has got to the divorce stage.A minority of people do still take guidance from the church and believe the once they have entered into holy matrimony then it is for life just as God ordained. In conclusion, like most of the civilised world I believe that the religious beliefs about sexual ethics are no longer relevant because civilisation has changed so much and people are wi lling to accept all that was once considered taboo by the church and are willing to open their mind about the change in religious beliefs and sexual ethics.

Heat Conduction

Experiment 16: Heat conduction Introduction In this laboratory you will study heat flow across a temperature gradient. By comparing the temperature difference across one material to the temperature difference across a second material of known thermal conductivity, when both are conducting heat at a steady rate, you will be able to calculate the thermal conductivity of the first material. You will then compare the experimental value of the calculated thermal conductivity to the known value for that material.Thermal conductivity is an important concept in the earth sciences, with applications including estimating of cooling rates of magma chambers, geothermal explorations, and estimates of the age of the Earth. It is also important in regard to heat transport in air, to understanding the properties of insulating material (including the walls and windows of your house), and in many other areas. The objective of this laboratory experiment is to apply the concepts of heat flow to measure the thermal conductivity of various materials. Theory Temperature is a measure of the kinetic energy of the random motion of molecules with a material.As the temperature of a material increases, the random motion of its molecules increases, and the material absorbs and stores a quantity which we call heat. The material is said to be hotter. Heat, once thought to be a fundamental quantity specifically related to temperature, is now known to be simply another form of energy. The equivalence of heat and energy is one of the foundations of thermodynamics. As the molecules in one region of a material move, they collide with molecules in neighboring portions of the material, thus transferring some of their energy to other regions.The net result is that heat flows from regions with higher temperatures to regions with lower temperatures. An exact calculation of this heat flow can be very difficult for materials with complicated shapes and complicated temperature distributions, but in some s imple cases the heat flow can be calculated. In this experiment, we will consider the heat flow across a plate of material of cross sectional area A and thickness ? x when its faces are held at constant (and different) temperatures, as indicated in Fig. 1. Figure 1 Heat flow across a plate. In this case the rate of heat flow H across the material is given by H = KA !T ! x ( ) (1) where ! T = T2 † T1 is the temperature difference across the plate and K is a quantity called the thermal conductivity. Note that this equation only applies because we keep the top and bottom at fixed temperature. In a more general situation, the flow of heat would alter the temperature of the top and bottom, and a more complicated approach would be required to deal with the situation. Heat is transferred more efficiently through shapes with a large area that are subject to a large temperature difference, but more slowly through thicker materials.If the units of H are J/s, that of A are m2, ? x is in m, and the units of temperature are ? C or K, then the units of K must be W/m-oC. Prove this for yourself, and show it in your laboratory book. Since the Celsius degree is the same size as a degree on the Kelvin scale, the units of thermal conductivity are usually expressed as W/m-K. We will use Eq. (1) to measure the heat flow through a material of known thermal conductivity and then use this result to determine the thermal conductivity of unknown samples forced to conduct heat at the same rate.Thermocouples In order to apply Eq. (1) we will need to measure the temperature difference ? T across our samples. It would be difficult to insert a thermometer into the gap between plates without disrupting the heat flow, so we will instead use a temperature probe that uses a device known as a thermocouple. 2 Figure 2. A Thermocouple A thermocouple is simply two connected wires made of dissimilar metals. Whenever two different metals contact each other, a small voltage difference is generat ed. This voltage difference is dependent on the temperature of the junction.If we measure this voltage difference with an accurate voltmeter, we can look up the temperature of the junction relative to the temperature of the connection to the voltmeter in a thermocouple table. The instrument used in this lab does the conversion for you, so can read the temperature directly. The thermocouple probe is now a very common device for measuring temperature, particularly in small places. For, example many medical thermometers are now based on thermocouples rather than the more traditional liquid in a glass tube. Experiment: Apparatus:The apparatus for this experiment are shown in the following figure, which also demonstrates how you will use the equipment. Figure 3. The apparatus for measuring thermal conductivity. 3 The apparatus for this experiment consists of a hot plate to supply heat, an ice bath to absorb heat, and plates of various materials through which heat will follow. Temperature s of the plates will be measured with a glass thermometer. In addition, the diameter and thickness of each plate will be measured with vernier calipers. Method Measure the diameter and thickness of each plate provided.Calculate the areas of the plates. Create the following table in your report and fill it in. Table 1. Dimensions of various plates Material Masonite Aluminum Plexiglass Plywood Teflon Using the glass thermometer, measure the temperature of the room and ice bath. Record your values. I. Thermal Conductivity of Plexiglass Construct a â€Å"sandwich† consisting of aluminum, masonite and plexiglass with the slots arranged so that thermocouples can be inserted on either side of the masonite plate. Place the sandwich on the hot plate with the aluminum side down. Place the ice bath on top of the sandwich.Switch the hotplate controller on and set the Variac to approximately 40% power. The exact value is not important, but if the power is set much higher some of the mater ials may get too hot. WARNING: Use extreme caution around the hot plate and when handling any of the materials that come into contact with it for the remainder of the experiment. The surfaces will become HOT! It will take up to 30 minutes for the heat flow to achieve a steady state. Monitor the progress by plotting the temperature readings T1 of the thermocouple 1 and T2 of thermocouple 2 as a function of time. Expect a maximum time of 45 minutes.Take readings every 1 to 2 minutes. If you miss a reading, skip it and record the next reading at the appropriate time on your plot. 4 Diameter (cm) Diameter (m) Area (m2) Thickness (cm) Thickness (m) You should find that the temperature readings eventually approach constant values. Even if they are still drifting after 30 minutes, the small changes to the heat flow will have only a small effect on your results. Record final values of the temperatures for the aluminum/masonite/plexiglass sandwich. You now have all the data needed to calcula te the thermal conductivity of plexiglass.See the â€Å"analysis† section later in these notes for details about how to do this. Calculate its value. II. Thermal conductivity of Plywood Carefully remove the Plexiglas plate and replace it with the plywood sheet (with slot down). Reinsert thermocouple 2 and place the ice bath back on top of the sandwich. Since a steady state heat flow has already been established in the aluminum and masonite, this new configuration should take only about 20 minutes to achieve a steady state. While you are waiting for the temperature readings to stabilize, you may wish to use the time to calculate the thermal conductivity of Plexiglas.If you do this, keep an eye on the temperature readings so that you know when a steady state has been achieved. Record the steady state values of the temperature for the sandwich of aluminum/masonite/plywood. III. Thermal Conductivity of Teflon Carefully remove the plywood plate and replace it with the Teflon plate (with slot down). Reinsert thermocouple 2 and place the ice bath back on top of the sandwich. Again, a steady state will probably be achieved in about 20 minutes. Record the steady state values of the temperatures for the sandwich of aluminum/masonite/Teflon. Analysis If e neglect the heat that escapes from the edges of the plates (due to convection and radiation), all of the heat provided by the hot plate must flow through each of the plates and into the ice bath, once a steady state has been achieved. Thus the heat flow through each plate must be the same throughout the sandwich. In particular, this means that the heat flow through the masonite is equal to the heat flow through the top material. Therefore we can write Hm = Htop . Using Eq. (1) we find that K m Am ! Tm ! xm = K top Atop ! Ttop ! xtop ( ) ( ) (2) The thermal conductivity of masonite is known to be 0. 0476 W/mK.You can derive an expression from Eq. (1) for the thermal conductivity of the top plate. 5 Use your measur ed values and the known value for the Km to calculate the thermal conductivities of each of the top plates used. Prepare a table like that shown below and fill in the values in your report. Table 2. Thermal conductivities of materials used in this laboratory. Material Calculated thermal Published value of K conductivity (W/mK) (W/mK) Aluminum Masonite Plexiglass Plywood Teflon The least accurate measurements in this experiment are the thermocouple voltages, which are only measured to 0. 1 mV accuracy.Based on this accuracy, estimate the uncertainty in the temperature difference across the masonite plate. Considering the uncertainty in this temperature difference only, what is the approximate percentage error in your calculated thermal conductivity values? Questions: 1. Use Eq. (1) to calculate the total rate of heat flow H through each of the plates in Part 1. (Note: The same value of H must hold for each plate, so you only need to use Eq. (1) once). 2. Do your results agree with th e expected values? If not, what measurements, processes, and/or assumptions do you suspect to have been significant sources of error? 6

Aetiology, pathogenesis, diagnosis and treatment Cystic fibrosis: role of P. aeruginosa infection in cystic fibrosis patients

Introduction Cystic Fibrosis (CF) is a genetic disorder of salt and water regulation in the cell. The disease is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene (Cohen and Prince, 2012). The molecular basis of CF depends on its transmembrane conductance regulator (CFTR) protein, which functions as a channel and regulates the movement of ions and water across the epithelial barrier. The barrier opens in response to increased levels of intracellular cyclic adenosine monophosphate (cAMP). The gene in normal condition is responsible for salt (chloride) and water balance in the body. However, if mutated, is not able to excrete out enough salt of the cell; thus resulting, the build of salt within the cell forming sticky mucus. If accumulated in the lungs, this sticky mucus may clinically affect the epithelial innate function of the lungs and may result in ineffective airway inflammation that fails to eradicate pulmonary pathogens (Cohen and Prince, 2012). The working mechanism of CFTR protein under normal condition is shown in figure 1. Studies have shown that increase in sodium (Na) re-absorption on the epithelial cells may indicate an event in cystic fibrosis lung disease (Cohen and Prince, 2012). These mutations on the (CFTR) protein have impacts on its production and transfer to the epical membrane of the epithelial cells, thereby influencing the conductance of chloride and bicarbonate ions across the channels resulting in the CFTR ionic imbalance of on the epithelial cells of different organs. This leads to the formation of excessive mucus in the cells, which provides an ideal condition for bacteria growth and multiplication. Interestingly, even uncommon lung bacteria such as pseudomonas have been found to inhabit in the lungs exploiting the ideal condition (Clunes and Boucher, 2007). Abnormality in the CFTR pathway results in the increase of glycolipids on the surface of CF airway epithelial cells. These glycolipids serve as receptors to increase the binding activities of bacteria, thereby facilitating the early infection process, which is a hallmark of the disease. Moreover, defect in CFTR gene is also associated with decreased nitric oxide concentration in the cell. Nitric oxide possesses antibacterial properties; thus, decrease in its concentration may predispose an individual to severe infections with faulty CFTR gene (Clunes and Boucher, 2007). In addition, the role of inflammation in CF pathogenesis seems equally important. Inflammatory response produced against the infectious pathogens in CF patients may have detrimental effects to the host cells. Inflammatory infiltrates including macrophages, neutrophils, cytokines and interleukins may induce tissue damaging responses, further deteriorating the lung function (Cymberknoh, et.al. 2013). Inhabitation of bacteria in cystic fibrosis lung As mentioned earlier, even uncommon bacterium including Pseudomonas aeruginosa can reside in the cystic fibrosis lung (Hauser, et.al. 2011). Pseudomonas aeruginosa is a gram negative, rod shaped, aerobic bacterium that prefers moist environment for growth. Commonly they are found in places such as sewage and in certain areas of the human body. Furthermore, they reside in lakes, moist vegetables, moist soil and streams. Studies have also suggested that that most human infections due to P. aeruginosa result due to contact with these natural reservoirs (Friman, et.al. 2013). Pseudomonas aeruginosa has been recognized as an important pathogen in CF. Soon after residence in the lungs, it becomes extremely difficult to eradicate them by antibiotics. The persistent presence of these bacteria in the lungs ultimately results failure of the immune system to provide a defense against them; this leads to respiratory failure resulting in death of the patient (Folkesson, et.al. 2012). Firstly, P.aeruginosa acquires the airway of the patient with cystic fibrosis, which occurs during the very early phase of the disease. Infection may ensue once this bacterium enters the CF host and colonizes the oropharynx, then to the lower respiratory tract by process of micro aspiration. Infection becomes intermittent at the initial stage as a result of acquisition of different strains. During the early stage of infection, the isolate looks like environmental strains, non-mucoid and susceptible to antibiotics. Eventually P. aeruginosa establishes itself and chronic infection ensues (Folkesson, et.al. 2012). In chronic stage of CF, P. aeruginosa produces a mucoid alginate by growing in bio-film of the end- bronchiolar space. It lacks lipopolysaccharide and becomes non-motile, resulting in the development of antibiotic resistance during. Despite the known mechanism and availability of antibiotics, P.aeruginosa is able to chronically infect the airway of patients with CF and is able to cause an unrelenting decline in pulmonary function and deterioration; but how these happen has been focus on intense research (Folkesson, et.al. 2012). Molecular pathogenesis of P.aeruginosa infection in CF The molecular basis of infection due to P. aeruginosa in CF is still not fully understood. However, it may be peculiar to a specific strain at the time of adaptation after acquisition. Studies have indicated that the persistence of the bacterium in the lungs might be due to its high level of propensity and the ability to adapt with environmental changes and stress (Hauser, et.al. 2011). aeruginosa possesses traits that enable them to colonize and persist in acute and chronic infection. These traits include; High resistance to antibiotics (Zhang, et.al. 2011) Effective cell-cell communication singalling for growth and multiplication (Friman, et.al. 2013). Ability to form biofilms, plethora and virulence products and metabolic versatility (Wagner and Iglewski, 2008). The biofilms are synthesized by the bacterium encased within a hydrated polymeric matrix and are clinically important; this is because, P. aeruginosa in this mode of growth utilizes it to cope with phagocytes by the neutrophils and macrophages, as well as to the killing by antibiotics. This allows them for persistent survival in chronically infected CF despite the continuous natural immune response and antibiotics effect (Zhang, et.al. 2011). The disease pathogenesis and severity is further triggered by inflammatory responses in the later stage of the disease. Mainly the pro-inflammatory enhancers become physiologically active in the absence of function CFTR gene. Although the exact inflammatory pathophysiology of CF still remains debatable, persistent infection, poor pathogen clearance, acidic environment and are considered some of the key triggers for initiating chronic inflammatory response in the lungs of the patient with CF (Pier, 2008). The mechanism is explained in figure 2. Synthesis of ceramide from sphingomyelin by acid sphingomyelinase (ASM) and degradation by acid ceramidase (AC) is optimal at an acidic pH, such as that of normal intracellular vesicles (pH 4.5). Lack of functional CFTR increases vesicle pH to 5.9, partially inhibiting ASM and highly inhibiting AC, resulting in ceramide accumulation in the vesicle and age-dependent pulmonary inflammation. Other properties of the cystic fibrosis–affected lung, including lack of the CFTR receptor needed for clearing Pseudomonas aeruginosa, enhanced mucin secretion, a dehydrated airway surface liquid, viscous mucus and DNA deposits released from ceramide-engorged apoptotic cells, also contribute to P. aeruginosa airway colonization. Eventually, this microbe establishes a chronic infection wherein bacterial cells reside in low-oxygen mucus plugs and become highly resistant to clearance or killing by host defenses (Pier, 2008) P.aeruginosa potentially synthesize factors such as proteolytic enzymes, which damage the host cells by altering the host iron-containing protein forming hydroxyl radicals that contribute to host tissue injury and inflammation; thereby decreasing the level of anti-inflammatory cytokines including IL-10, and at the same time, activating neutrophils in the airway lumen. Continuous recruitment of these neutrophils induces tissue damaging inflammatory response mainly affecting pulmonary tissue. Furthermore, neutrophils trigger the production of pro-inflammatory cytokine such as IL-8, which further contributes in the tissue damage process. In addition to pro-inflammatory cytokines, neutrophils also release the oxygen free radicals that induce apoptosis (programmed cell death) of the epithelial tissue in the lungs. Thus, to conclude, the role of neutrophils in airway inflammation in patients with CF seems crucial. Instead of providing innate immunity to the infected lung, it rather trigger s detrimental inflammatory response and promote the growth of P. aeruginosa though the production of different growth enhancing cytokines, leading to the destruction of the lung tissue (Sagel, et.al. 2009). The effectiveness of the immune response in CF is exploited, allowing the establishment of a relentless cycle, whereby persistent bacteria cause increased inflammation that itself leads to increased bacterial densities, which in turn results stronger inflammatory response (Sagel, et.al. 2009). The net result is progressive tissue damage and pathological consequences and sequelae of CF that include mucopurulent plugging of bronchioles, chronic bronchitis (inflammation of the bronchioles) and bronchial gland hyperplasia (increase in the cell size of bronchial gland cells). The airway later becomes dilated and results bronchiectatic due to loss of support cartilage (Pickett, 2013). Treatment options for cystic fibrosis The decision to treat patients who are infected with P.aeruginosa can be very challenging. Prolonged treatment with antibiotics can have toxic side effects, as well as increases the chance of microbial resistance in the patients. Also, prolonged treatment may cause long term harm. Data suggest that 80% of the patients with CF die indirectly or directly from pulmonary disease (Hurley, et.al. 2012). Clinically, there has been very little progress in the development of new antibiotics with novel mode of action. Recently, researchers exploited the adjuvant therapeutic agents that may be used alongside the conventional antibiotics. Source control measures, de-escalation of antibacterial should be followed up in patients with clinical response, especially with known antibacterial susceptibilities (Hurley, et.al. 2012). Considering the virulence of this pathogen, the progress of various strategies such as efflux pumps and lectins, the use of iron chelators, immunization, immunotherapy, and inhibition of quorum sensing are currently being tested clinically for the better management of the disease. It has also been suggested that the impacts of intervening virulence of P. aeruginosa should also be assessed (Hurley, et.al. 2012). Some novel therapies are also based upon the fact that CF is caused by the mutation of the gene encoding CFTR protein; targeting the defects produced in CFTR with invacaftor in one such approach. This novel treatment seems promising in patients with specific genotype of CF. Although the long term-outcome remains unknown, the development of CFTR targeted drug is an important milestone in CF (Petit, et.al. 2012). More recently, gene therapy has been extensively studied for the complete cure of the disease. However, the technique is not easy and has several limitations and hurdles. For instance, the research on this approach is very time consuming and often very expensive. However, focus of research has been on identifying the optimal vector for gene therapy (Picket, et.al. 2013). Thus, the management of CF has been a major challenge ever since the discovery of the disease. However, advancement in medical technologies and treatments has improved the prognosis of the disease. More sophisticated treatment including gene therapy (replacing faulty CFTR gene with a normal gene) has been the focus of intense research. P. aeruginosa resistance in CF Pseudomonas aeruginosa is one of the common infections in western society, because of its high level of resistance to antibiotics. The synergistic relationship between the outer membrane permeability and the efflux pumps is the most important factor influencing intrinsic antibiotic resistance in Gram-negative bacteria like P. aeruginosa (Liu, et. al. 1996). The high level of P. aeruginosa resistance is due to the acquired genes coding for amino glycoside-modifying enzymes or periplasmic beta-lactamases or mutations in fluoroquinolone targets (Liu, et.al. 1996). Low outer membrane permeability, which is caused by either less production of the OprD porin, or by expressing multidrug resistance efflux pumps contributes to high level of intrinsic antibiotics resistance (Liu, et.al. 1996). Numerous efflux pumps such as MexAB-OprM and MerXY-oprMb MexAB-OprM, MeXY-OprM, MexCD-OprJ, MexEF-OprN, MexJK, MexGHI-OpmD, MexVM, MexPQ-OpmE, MecMN and TriABC are encoded in the genome of Pseudomonas aeruginosa. These are of clinical importance because of their chemical ability to remove chemical-unrelated antibiotics. Among all, resistance-nodulation division (RND) super family contains the main efflux pumps of P. aeruginosa. This efflux pump has been discussed in greater details below. The energy source is derived from its proton motive force. Resistance Nodulation Division Efflux Pump Structure There are five families of multidrug resistance efflux pumps which include the ATP-binding cassette (ABC) super family, the major facilitator super family (MFS), the multidrug and toxic-compound extrusion (MATE) family, the small multidrug resistance (SMR) family and the resistance nodulation division (RND) family (Paddock, 2006). Efflux of antibiotics from the periplasm is a critical mechanism of antibiotic resistance utilized by Gram-negative cells. P. aeruginosa is capable of actively effluxing antibiotics from the periplasmic space using efflux pumps primarily from the RND family. The RND complex is tripartite in nature, composed of an outer membrane channel protein (OMP), inner membrane RND transporter, and a membrane fusion protein (MFP) (Kumar and Schweizer, 2005). The RND transporter provides the energy for the molecular transport and is often referred to as the RND pump protein (Misra and Bavro, 2009). The OMP interacts with the RND protein in the periplasm producing a chann el capable of transporting antibiotics into the extracellular space. The MFP is believed to stabilize the interactions between the RND transporter and the OMP (Misra and Bavro, 2009). All three of these components are essential for efflux function. The RND transporters are comprised of a homotrimer folded into a ?-helical transmembrane domain, with a large, soluble periplasmic domain. The top of the bacteria have semi-permeable membranes which may limit the passage of some types of antibiotics into the cell (Avrain, et.al. 2013). Multidrug resistance efflux pumps allow the bacterium to pump antimicrobials out of the cell. Porins maintain osmotic pressure by allowing the entrance/exit of hydrophilic small molecules but do not permit the passage of larger molecules. Enzymes can modify the antibiotic so that it is no longer recognized by the target, or modify them so that they are no longer functional. This is particularly prevalent with antibiotics that alter the ribosome or interfere with ribosome binding to inhibit protein synthesis. Inhibition of mRNA synthesis occurs by binding to DNA dependent RNA polymerase inhibiting initiation (Avrain, et.al. 2013). The mechanism of antibiotic resistance is shown in figure 3. Fig3: Different mechanisms of antimicrobial resistance in Gram-negative bacteria (adapted from Fluit, et.al. 2001). In the figure, A represents mRNA and B represents tRNA. When exposed to antibiotics, MexAB-OprM and MexXY-OprM remain inducible but the rest of the systems when expressed in resistant strains may immensely contribute to biocide or antibiotics resistance. Antimicrobial components are released by the RND systems and these include first line anti-pseudomonal drugs such as beta-lactams and beta-lactamase inhibitors (Poole, 2011). Furthermore, alteration or loss of the outer membrane porin protein OprD is yet another common mechanism of resistant to carbapenems(Wang, et. al. 2010). Since P. aeruginosa infections are usually treated by the use of fluoroquinolone (Ciprofloxacin), its high level resistance is as a result of mutations in the DNA gyrase and topoisomerase IV enzymes, which target these antibiotics. Outbreak of P. aeruginosa An outbreak can be defined as two or more sterile site isolate of the same species, with the same antibiogram, from different babies within the space of two weeks. A Pseudomonas aeruginosa infection outbreak on neonatal intensive care units reflects a degree of breakdown in infection prevention measures. Poor hand hygiene, low nurse: patient ratio, inadequate spacing between cots, overcrowding, environmental colonization (especially of water systems), inadequate cleaning of common use equipment, injudicious use of antibiotics, particularly broad spectrum and prolonged courses and delaying the introduction of material breast milk, all contribute to the emergence of outbreaks. It has been reported that infection from P. aeruginosa usually occurs 48hrs after birth, which affects two to three per thousand babies in the UK (Walker, et.al. 2013). The occurrence of the infection is even higher in those born prematurely or with surgical conditions (Durojaiye, et.al. 2011). Microbiological analysis In previous studies, (Walker, et.al. 2013) carried out the following microbiological investigations. Dismantling of Taps Taps and flow strengtheners from relevant hospital were dismantled, categorized into components, swabs and water samples were also taken. Samples for microbiological assessment were placed in 10 ml of maximum recovery diluents together with 10 sterile glass beads (3 mm diameter, VWR International, Lutterworth, UK). The surface of each component was scraped with a sterile plastic loop (Sterilin, Newport, UK) and the suspension was then vortex-mixed (10 s) to remove biofilm and to suspend the micro-organisms. Each sample was then spirally plated (Don Whitley, Shipley, UK) on to plate count agar (Oxoid, Basingstoke, UK) and Pseudomonas selective agar (PCN, Oxoid, UK), for determination of aerobic colony count (ACC) and P. aeruginosa count respectively. This was then incubated at 30Â °C on (Plate Count Agar) or at 37Â °C (PCN) for 48 h. It was found out that complex flow straightener had significantly higher P.aeruginosa counts (P

Question 1 1. 1. Write a paragraph in which you discuss the role of communication in creatinga sustainable positive atmosphere in your classroom. Communication is the transmission of an idea by someone, thesender, and the understanding thereof by another, the receiver. Communication is important to the success of any relationship,without it the relationship is doomed to fail. In order to increase thequality of the relationship the communication needs to be effective.Effective communication between the educator and the learners Inhis/her class is essential in order to create and maintain a positiveatmosphere in the classroom. 1. 2. Write a paragraph in which you discuss the importance of establishingpositive educator-learner relationships in the creation of a sustainablepositive atmosphere in your classroom. A positive educator-learner relationship is important as it enablesboth the educator and the learners to risk being honest with eachother, care about each other, it promotes inter dependence, ensuresmutual needs are met and allows each individual to develop their  own individuality.The creation of the above leads to trust between the educator andlearners and as such will result in a positive classroom atmosphere. Creating a good educator-learner relationship involves the following(Coetzee 2010:87): ? Creating open, professionally appropriate dialogue with learners. ?  Ã‚  Systematically building better relationships with learners. ?  Ã‚  Maintaining a high rate of positive to negative statements. ?  Ã‚  Communicating high expectations. ?  Ã‚  Creating opportunities for personal discussion.Guidelines that can be used to avoid the negative effects of educator  expectations are as follows (Coetzee 2010:87): †¢ Use sensitive information on learners carefully. †¢    Be flexible in your use of group strategies. Be careful how you respond to low-achieving learners duringclass discussions. ? Use materials that show a wide range of ethnic group s. Be fair inyour evaluation and disciplinary procedures. ? Communicate to all learners that you believe that they can learn. ? Involve all learners in learning tasks and privileges. ? Monitor your non-verbal communication. . 3. Discuss how you would promote learner participation in a multiculturalclassroom by creating a learning environment that supports socialising andintercultural interaction . ? I would first read through all the learning materials for that givensubject in order to determine if there is any aspect of the work or  activities which may be culturally insensitive to any of thelearners in the class. ? I am aware that cognitive learning styles are culturally dependentand therefore will use a variety of teaching styles, methods andstrategies in my teaching of the class. ?In order for the learners to participate and actively cooperate witheach other it is necessary to be aware of any instances of  cultural insensitivity immediately and take action, a way to avoidthe se situations, I could allow those members of differentcultures to explain about certain aspects of their culture to theother members of the class. This way I as the educator and theclass will learn about other cultures. ? I expect all the learners in my class to achieve to the best of their  ability as all people are able to learn provided they put in the timeand effort to do so.I am also aware that the academic andlearning ability of learners differ, so they at the beginning of theacademic year are required to set their own personal goals whichthey then work towards. These goals set are at levels slightlyabove what each learner believes they can achieve in order tochallenge them. When checking work done in activities the class needs to assistthe learner who is answering the specific question if they makean error in order to correct it, if they are unable to detect or  correct the error, I as the educator assist in guiding them to thecorrect answer. Question 2 2. 1.Name five wa ys in which educators can improve learner motivation in theclassroom . a) Make the learning task more challenging. b) Place less emphasis on teaching and grades. c) Move from extrinsic to intrinsic motivation. d) Have high expectations of each learner. e) Increase the learners ¶ perception that they control the learningsituation. 2. 2. Draw up the following of a classroom policy: 2. 2. 1. Aims and objectives of our class . Class Aims: To achieve our academic and intellectual potential through hardwork as a cooperative group, while promoting the acceptance of  others and respect for others.Individual Objectives: Each individual sets their own goals to achieve at the end of theyear (long-term) in order to contribute to the overall class aim. In order to achieve their own end of year goals the learners setshorter term goals in order to assist them in achieving their long-term goals. 2. 2. 2. Rules for our classroom . 1) We must respect ourselves, others and the educator. 2) We must be on time. 3) We must enter the class quietly, and get ready to work. 4) We need to bring all our stationary and books to class. 5) We must raise our hands to ask questions in class. ) We must not eat nor drink in class7) We must never disrupt another learner ¶s work. 8) We don ¶t leave litter on the floor, we put it in the bin. 2. 2. 3. Task division . Educator: ? Always prepared and punctual. ? Provide assistance to learners. ? Manage the classroom appropriately. ? Discipline learners fairlyLearners: ? Ensure all work is completed on time. ? Maintain a clean learning environment. ? Respect one another. ? Make sure all learning materials are brought to class. 2. 3. Define the following concepts: 2. 3. 1. L eadership The ability of an individual to influence other individuals or a groupto achieve goals. 2. 3. 2. C ntrol Assessment of work done and where necessary to realign andcorrect work done which is incorrect or not up to standard. 2. 3. 3. I ntrinsic motivation An inner d esire to be successful at a certain task (self-motivation) 2. 3. 4 . C ommunication The transmission of an idea by someone, the sender, and theunderstanding thereof by another. Communication can be verbal or  non-verbal. 2. 3. 5 . Co-operative learning A team approach to learning where each member of the group isdependent on the other members to accomplish a specific learningtask on an assignment. 2. 4 . Describe the autocratic and democratic styles of classroom management .Autocratic leadership style: Autocratic leadership is an educator-centred approach to theclassroom which is characterised by the strong leadership role of theeducator. The main focus of this type of leadership is on thecompletion of tasks and the learners ¶ ability to listen, work and do. Theadvantages of this type of leadership include the promotion of goodorder and an established routine in which some learners feel moresecure. The drawbacks of this type of leadership include one-waycommunication, rigid disc ipline, passive learner participation, a morereserved and unapproachable educator and little room for creativethinking.Democratic leadership style: This leadership style is characterised by educators that have goodsubject knowledge, who are good natured, helpful, fair, and warm. Educators who practice this management style encourage learner  participation. The advantages of this type of leadership include learner  confidence to participate in classroom activities, a relaxed positiveatmosphere and learners constantly being involved in learningactivities. 2. 5 . Explain how a message is conveyed by referring to the communication processmodel . In order for there to be communication there first needs to be apurpose for communication or a message to be conveyed.Thismessage is then encoded by the sender and passed onto the receiver  via a communication medium. The message is then decoded by thereceiver. This results in a transfer of meaning from the sender to thereceiver, who then may give feedback back to the sender. Question 3  µ A delict is an unlawful, culpable (intentional or negligent) act (or omission)committed by a person, which infringes the rights of another or causes himor her harm.  ¶ (Coetzee 2010:188) ? To constitute delict, one person must have caused harm or damage to another byhis or her action or conduct .The conduct must be voluntary human action and maybe either a positive action or an omission .  µ In terms of this element of delictual liability the school can be held liable asthey failed to remove the piece of steel or at least clearly demarcate thearea around the piece of steel, in order to make people aware of it. Thecoach, knowing that there is a possibility that players could fall during thewarm up due to the nature of the sport, could also be held responsible asthe teams were responsible for choosing a warm up area and the coachshould as such have checked the area for any objects that could causeharm to team members. The act w hich causes harm must be wrongful, that is, it must be legallyreprehensible or unreasonable in terms of the legal convictions of the community . To test for unlawfulness, the boni mores principle is applied . The question here iswhether the harm caused was unjustified in the circumstances . I n the absence of  wrongfulness a defendant may not be held liable .  µ The school can be held liable as they should have taken all precautions tohelp to prevent an injury of this nature to any person on their schoolgrounds.Knowing that they were hosting a basketball tournament theyshould have removed any objects that could cause injuries to any playersor clearly demarcate the areas where there could be concerns over theplayer ¶s safety. The coach in being responsible for the safety of his teamshould have thoroughly inspected the area chosen for the warm up for anydangerous objects. ? The act must be the result of fault in the form of intent (d  olus) or negligence(culpa) . Fault refers to blameworthy attitude or conduct of someone who has actedwrongfully .  µThe coach of the team was negligent as he should have inspected thearea for any danger to the players, if he had done so he would have seenthe piece of steel and then either have chosen a different warm up area or  at least warn the players to either avoid that area or be careful around it. The school could be seen to be negligent for failure to remove the piece of  steel or clearly demarcate the area around the piece of school. ? There is a casual relationship between the conduct of the perpetrator and the harmsuffered by the victim . I general, it should be shown that the person ·s injury didresult from the actions of the person charged with negligence . I n other words, theremust be a clear casual relationship between the act and the injury . A person cannotbe held liable if he or she has not caused any damage .  µ The school ¶s negligence in not removing the piece of steel or demarcatingthe are a around it resulted in the injury to the player, as such they can beheld liable. The coach for not thoroughly inspecting the area in which theplayers would warm up could also be held liable. ?A delict is a wrongful and culpable act which has harmful consequences . Damagesin the form of patrimonial loss or non-patrimonial loss must be present . There mustbe a connection between the negligent conduct and the injury (physical or mental ) . To receive an award for damages, a plaintiff must have suffered an injury as a resultof the defendant ·s negligent conduct . The plaintiff must prove that some damageoccurred . Although the injury or damage does not need to be substantial for anaward to be ordered, the injury must be real rather than be imagined .The courts aregenerally reluctant to award damages where there is not some form of injury .  µ Damages are present which are due to the negligent conduct on the partof the school, not removing the piece of steel or demarcating the areas urrounding the piece of steel, and coach, for not thoroughly inspectingthe area on which his players will be using to warm up. Contributory fault is where a learner does not show the degree of carenormally expected form someone of his or her age, knowledge andexperience.If this is present the educator will not be solely liable for anydamages resulting from an injury by his or her act. In the case in question,if the basketball tournament is for a junior age group (ie. under 15 ¶s) or asenior age group (ie. under 18 ¶s) will determine if there is contributory faulton the part of the learner ¶s. Under 18 learners ¶ can reasonably beexpected to be responsible enough to check themselves for any danger onthe warm up area chosen. Whereas the under 15 learners ¶ cannotreasonably be expected to check for any danger.

Pharmacology assignment Example | Topics and Well Written Essays - 2500 words - 1

Pharmacology - Assignment Example Healthy participants will be assigned to group A and B. subjects in group A were given 50mg of JP234 from day 3 to day 10 and warfarin 1.5 mg from day 7 to day 14. Participants in group 2 will receive 1.5 mgs of warfarin from day 3 to 10 and then 50mgs once a day from day 7 to 14. Both drugs will be administered for the first fourteen days while the remaining six days will be utilized as washout period. Plasma levels of the drugs will be assessed in both groups. Monitoring the plasma concentration is essential in drug interaction studies. The subjects will be closely monitored for heart activity, clotting factor level and heart rate through utilization of an electrocardiogram. The drug is believed to be well tolerated during clinical trials and has less contraindication association with it (Simon, 2007). The result of the finding will be utilized in identifying the action of the new drug on the metabolism of warfarin. Through blood sample study and the hearts activity measure, the ef fectiveness and the action of JP234 on warfarin will be measured. The study aims at finding out the effect of JP234 on the action of warfarin. Any changes on the participants will be recorded. Tolerability and the safety of the drug will be assessed too. JP234 is well tolerated during clinical trials and there is no contradiction associated with it. The drug when administered is effective in doses of 50, 75 or 100mg once daily. The drug is metabolized in the liver and has a half life of about 24 hours. In vitro studies indicate that the drug can induce CYP2C9. Patients with chronic atrial fibrillation should be anticoagulated to hinder thromboembolism from taking place (Goodman, 2005). Patient taking JP234 are recommended to take warfarin that is partly metabolized by CYP2C9. JP234 is an antiarrhythmic drug and is usually excreted in the liver just the same as warfarin. The new drug is considered an inducer of CYP2C9 which takes
