string(40) " took risks that I was willing to take\." Response-ability says Perls, is a misused word. It â€Å"means the ability to respond: the ability to be alive, to feel, to be sensitive. † (GTV, 100). We will write a custom essay sample on Clearing the Mind Weeds in a Counselling Profession or any similar topic only for you Order Now It does not mean â€Å"obligation. † It doesn’t mean â€Å"duty. † Duty- what is that anyway? One way or another, it is something that I’ve been directed to do without asking why. I do it automatically, without accepting responsibility for my actions. This was the trait that saw me through the travails in my life where I moved from letting others be responsible for me to taking responsibility for myself. Perhaps this is what motivated me to pursue my goals without relying too much on my family resources. I learned early on not to assign the cause of my behavior to my parents or my past or even the wealth of my family. In the process I learned this most important value of responsibility that kept me grounded and helped me in my studies and work. However, it was not an easy journey. I cannot consider my life as an extraordinary this world had ever had. Each person has a story to tell and I must say mine is not really something different. While some people spend their lives with lots of colors around them, some just do not – and as much as I hate to admit, I spent many years of my life belonging to the second group. I go with flow and that has always been the case. It goes this way: I knew I need to attend school and so I did. I have to do well in school or else I will suffer from all the criticisms – the usual criticisms. It is never easy to live in other people’s expectations to the point that it is what they want that drives you. It is your body under their minds. I can now imagine how pathetic that was. All the while, though, I do not think I was as inspired as the rest of the class was. I did not make lots of friends from school. No big deal! But there were times when I also deal with thinking of the reasons for the ‘empty’ life. Those days would usually end with me getting no answer than ‘It must be me†¦Ã¢â‚¬â„¢ Although I acknowledge the fact that each of us has our own set of preferences and all the while, I lived in the thought that I just prefer to live my life like this – lonely, detached, alone. It was tiring when you care for no one and more when no one cares for you. In a way, my opinions have been changed because I have learned to create a balance in obeying orders. It was there where I learned that there is blind obedience that ignores all rationality and obedience based on freedom. Those involved in a transaction are independent—they can walk away from the deal if they don’t like what’s happening. And just as they are free to leave, they are also free to stay. In fact, if one is not free to walk away, he is not free to choose to stay. Some of my own teachers then helped me develop a sense of competence and love of learning. Though some helped me find my own directions and make my own discoveries, others taught me to follow orders and not ask questions. If I had enough teachers who cared more about their authority than about my growth, I probably would have left school more a robot than when I entered. I learned that to the degree that I’ve been conditioned in ways that block my process of growth, I act like a robot. Something happens near me and I respond. No time for choice, between the stimulus and the response. I’m reacting entirely to preprogrammed instructions in my memory. In examining the idea of obedience in the context of my schooling, I remember the works of authors Darymple and Milgram who provided two points of views. In doing so, I got several insights especially when I began examining the idea of the authors in the execution of orders. In the course of my study, I was able to see where the authors were coming from in their pursuit of obedience. I have learned that if I want to increase my power of authority, I can develop and cultivate my honor rather than seek honors, status, recognition and praise. Others will honor me when they know that not only do I have the capability to do what is necessary, I execute it in grace and honor. I started my career as an advocate of science and technology. Yes, my first degree was Bachelor of Science in Mechanical Engineering. I used to get fascinated with breakthroughs science gets to offer – all those inventions and advances in technology. Awesome! Hale great! Breath-taking! Fantastic! All those praises†¦ Nothing can beat the feeling of having invented something out of nothing. Or the feeling of being the one to drastically improve the current state of something for the benefit of people around the globe – it is always satisfying! But who could tell it was not really a career of my own choice? I was one of those high school graduates who do not really know what they want to happen in their lives. And so, without any particular basis, it was Bachelor of Science in Mechanical Engineering that I ended up with. I was aware of the good future this field has to offer. I have known of lots of people who have succeeded in this career who took up this course. I, at least, had this driving force to continue with my study. Fair enough to push me to strive harder and harder. I just told myself I need it or else I will end up with nothing. Looking at my Engineering career, I know that I took risks that I was willing to take. You read "Clearing the Mind Weeds in a Counselling Profession" in category "Papers" They were statements of who I am and who I am not. We can almost never know enough to be sure what is going to happen as a result of what we do. We can only guess, assume and expect, with varying degrees of certainty. At this moment, under these circumstances, with knowledge I have now, I make my choice. I live with its results. The conditions of my life today are the result of choices I made yesterday. Everyone â€Å"blows it† now and then. If I think clearly and act as honestly and wisely as I know how, that’s all I can do. We can’t help some of our suffering, but sometimes we ourselves create the rest. Now, I have learned to take my failures and my half-successes as a normal part of life. My â€Å"errors† and â€Å"defeats† sometimes teach me more than my successes. In an important sense, they are not failures at all. In the process, I learned interdependence. Interdependence asks, â€Å"What can we do and be together? † Interdependence asks the synergy question. It is not external but the power that focuses internally. It relies on the capacity that people have within themselves to be tougher on themselves, to push themselves harder when they are subsuming what they want in the cause of something that’s greater. Ultimately, that’s what sacrifice is all about – giving up what I want now for what I want the most. Giving up what does not matter as much, for what matters more. Sometimes the needs of the few are sacrificed for the needs of the many. Sometimes the sacrifice is just the reverse, and the needs of the many can accommodate the needs of the few. The needs of the few are worth the sacrifice and commitment of the many. Self-control, demonstrated in a group setting, is very powerful. Each person essentially says, â€Å"I give myself to it, because it is the right thing to do. † Many enjoy learning but they do not always like being taught. It requires humility. It requires recognition, first within and then to those who would teach you. It was at this phase of my life where I learned to be a true leader—one who is not afraid to learn new things and try out new ways of doing things. When a leader says one thing, the effect is intent listening and execution. The art of listening which I learned well at this point enabled me to come to the other person in terms that they understand, because I now approach them from their frame of reference, their desires, wants, and needs. Indeed, true leaders are able to connect with people well. I started my career as an advocate of science and technology. Yes, my first degree was Bachelor of Science in Mechanical Engineering. I used to get fascinated with breakthroughs science gets to offer – all those inventions and advances in technology. Awesome! Hale great! Breath-taking! Fantastic!

Fair enough to push me to strive harder and harder. I just told myself I need it or else I will end up with nothing. Description of a Learning Event in Listening and Being Listened to I remembered an incident that was the turning point in my career. When I read the book on Teach only Love, I knew that I wanted to shift my course. I wanted to go into Counselling. There was something about the book that touched the innermost being in me. I wanted to shift my profession from Mechanical Engineering to Counselling Studies. These are far apart degrees and, yes, I did not see myself engaging in counselling. No, not even in my wildest dream. But this is not a dream. Yes, I am living in reality and the reality is that this is the vocation of choice. This is where I find myself, my heart. This is where I belong. It is true what the â€Å"magical† book says – that it is from your past where you draw your present. If not for the thousands of rejection, if not for the feeling of inferiority, if not for the lack of self-confidence, I do not really think this book would have as much effect on me as it had. I was so excited about it that I immediately told it to my best friend. I knew he would understand me more than anyone else. As I was telling him of my decision, I could see that he was getting listless. I saw him avoiding my eyes as soon as I uttered those words. I could not blame him. We both dreamt that we would finish the course and here I was bowing out on him. After a while, I responded, â€Å"You’re angry. † he says, â€Å"Why would I be angry? † I was sure that my friend was angry but resisted knowing his own anger because of his personal values in which anger is a wicked emotion. I knew that there was resistance to acknowledge this since he was terrified of losing control, unable to think of himself as angry because of our friendship. He seemed to be projecting his anger on me at that moment and I could feel it so strongly. In a way, I was able to gently tell him how he looks and sounds which made him aware and he then began to talk about his anger. At that very moment I felt like a real professional counsellor. I was able to gently guide him about his feelings, even if I was unsure of what to say at all. I knew that if I uttered the wrong words, he will walk out on me. But I gently drew out his feelings then. I tried to help him break out of his sullen, angry depression. Finally, he suggested that he punch a throw pillow bunched up in a corner of the couch in a corner of the student lounge. There were a few students around. He did not wait for my reply. He started punching, harder and harder, until he was breathing fast and deeply, feeling the relaxation. He did this several times, while I sat quietly, finally remarking on how much different his face looked—smoother, less tense , not so red under the eyes. He countered how clear his mind seemed, that it was the first time in several days that he really felt relaxed. I managed to ask him if those punches were meant for me because I was planning to change courses. He said, he thinks those were more of his angry feelings because he was obligated to take up Engineering when he wanted to go into the arts. In an instant, I empathized with him. I knew how it was like to take up something where one’s heart was not on it. He then began to talk quietly about his father, and how he wanted him to take up Engineering instead of Speech and Drama. After a minute or so of that conversation, I asked, â€Å"How do you feel now? † He was beginning to feel tense and angry again. The object lesson for him was (1) the need for physical release for his anger, and (2) the amount of control his thoughts exercised over his feelings (Ellis, 1966). The heart’s yearning The pent-up feelings seem to come mainly from either of two frustrations, my classmate was having feelings and thoughts which appear to be enormous, odd, scary, and feeling cut off from other people because of his own inferiority with our other classmates. I have learned from this incident that catharsis is often not enough. At some point in the helping process, the understanding, which comes with a careful analysis of anger, may be healing. My classmate was able to see his anger in the context of internal polarity or conflict, between desire for freedom and a sense of duty, and be liberated by the understanding. The precise descriptions of the anger experience helped my classmate by removing excess emotional baggage. Insight is curative, but most frequently, both client and counsellor will find additional action useful to manage anger. For me, this action is intervention, helping my classmate change attitudes about each of our decisions. It was a poignant moment I would never forget. I knew he wanted to lash out his anger on me. Although I appeared to be so passive all the while, in my heart I know I long for something. That something, however, is unknown. I do not know if I am just one those people who experience wanting something they do not exactly know what or looking for something they do not know, for sure, if existent. Can you just imagine how if feels to be in the dark? Be somewhere without any clear direction? They say that every little thing just takes a little of getting used to. Oh, well, probably, as I seemed to have been used to the feeling of being lost. It was sad but true. Despite the lack of light in my life, I never questioned the existence of the Great Someone Up There. I perfectly know he is there. I do not recall how often I scream for His help. Maybe not that often but, of course, I do. I do and in my heart, I know I am not essentially alone all the while. However, there are moments when I tend to question the number and quantity of challenges facing me. There seems to be an imbalance in load allocation. How come I felt so lost while others follow certain direction? How come I do not know what I want in life while others are so certain of what they want in theirs? How come I do not seem to possess enough reason to be happy and complete. I often envy happy and satisfied people, I must admit – but I do not harm to them. I just envy them, that is it. And more often than not, I wish I were in their shoes. In all the insecurities I have inside, there were times when I ask myself if this is something I caused. What is that something I failed to do? What is that something that I can probably change to make a difference? What could be missing? I have heard of success stories about people who started with nothing and ended up having the life they have always dreamed of. Can I not be one of them? My concern is never monetary. I did not wish for the whole world. I just want a piece of it – a piece of it where I can enjoy life to the fullest. I did not ask for extravagant things. What would a loner do with those? I doubt if anybody could really enjoy everything alone. I did not wish for fame. I have lived my life not having the attention of the whole world. I just want some compassion and feeling of belongingness. I did not wish for power as I have never ever seen myself mandating others or controlling the world. It could be that I long for power but that power is the power to appreciate and enjoy life, the power to make people see me as a sensible being worth the company, the power to contribute to the ‘real’ things in this world. In short, I was never a materialistic type. There are things I lack from within and that is something I longed for to fill in. I used to have a very narrow view of things in life. I exist. I have to live. I have to survive. I used to find the question, â€Å"What am I here for? † or â€Å"Why do I exist? † as cliche that should have been buried decades back. Come on! You are here because you are here and there is just nothing you can do about it! It is not a problem needing solution. It is just a situation that you have to live with. You are left with just two options – either you continue to exist or you end your own existence. Is that something needing some sort of profound thinking?! Life is as plain as that. You just have to go with the flow. The True Art of Listening Counsellors can provide instruction in observing and listening by making these skills an integral part of their ongoing activities. The dominant characteristic of observing and listening activities are often appropriate for poor readers or students in the primary grades. To believe that all students will learn the same things at the same time, at the same rate, and with the same degree of retention is sheer fantasy. In almost any classroom at any grade level, the range of students’ abilities, interests, talents, knowledge, previous experiences, personalities, learning styles, dispositions and needs is so great that it is staggering. This kind of individualized instruction has resulted from efforts to make teachers more responsive to individual students and their instructional needs. Activities that focus on observation skills emphasize things that children can observe; things that can include objects, behaviors or processes. Teachers need to adapt a curriculum appropriate to the needs of the students. Some of the best teaching resources for students with these kinds of learning difficulties are those teachers have developed themselves. Teachers could build most of the student activities. This will go into refining—that is, they will be tried out with students and then revised—but once developed, they can become resource to be used in future years. Before teachers can duplicate an activity, it would also be wise to share it with someone he/she can rely on for honest feedback—a colleague, or a fellow student teacher. One is almost certain to find that what one thought was perfectly obvious is not, and thus gain a chance to make appropriate adjustments before trying it out with one’s students. It is best to start small and then build the collection of materials slowly and steadily. Responsibility in everyday life From then on, after realizing the implications of these theories, I began to take responsibility for my life now at work and beyond–which involves self-management competency. Often, when things do not go well, people tend to blame their difficulties on the situations in which they find themselves or on others. I have learned that effective self-management does not fall into this trap. Self-management competency includes integrity and ethical conduct and personal drive and resilience. I agree with what Jay Greiner posits about the reason why it is most difficult to take personal responsibility for mistakes. It is because one feels threatened and insecure. The word responsibility itself is a misused word. More than postponing automatic assumptions, Perls, the renowned psychologist sees growth as a move from letting others be responsible to taking responsibility for oneself. Education in today’s environment will be successful if we formulate activities that are engaging as much as they are educational, and if we adapt to new technologies that will help complement classroom interaction. I have further learned that drive and resilience are especially important when someone sets out to do something no one else has done or when that person faces setbacks and failures. The responsibility aspect which Jay Greiner talks about will spur more insights about ethical dilemmas that arise at all levels in the business world. People, whether employer or employee, may face situations in their work or dealings with other people in which ethical dilemmas arise. The individuals in these cases are faced with ethical questions in their relations with customers, employees, and members of a larger society. More often than not, the answers to these questions are difficult because it involves weighing of values. Conflicting values in a given situation are not capable of compromise. One has to choose one over another. Sometimes, the ethically correct course of action is clear, and hopefully individuals act accordingly. But the answers are often not simple. The dilemma is most commonly presented when ethical concerns come into conflict with the practical demands of business. This is related to the proper obedience and responsibility that I discussed earlier. Knowing how to negotiate and persuade people would be very essential for the progress of my future career. Through interactions with various kinds of people in a potential workplace, I get to know particular complexities of people and use this to a good advantage. I believe that an effective leader is a pathfinder and a team builder. As pathfinders, he has to recognize needs and accommodate the legitimate needs and wants of all stakeholders by clarifying: Vision, Context, Direction, Location, Goals, Strategy, Purpose and Pace (Business Ethics). As team builders, he has to help others achieve as they create healthy, safe conditions for risk taking, help others become leaders, provide resources and be a resource themselves, help some move from dependence to independence, help others get things done; and help determine how people work together. In the course of my experiences as a leader in the fields I have chosen, I have come to understand how my social environment wants me to be, and why, I can more wisely choose which people and events in my environment I want to make a part of me, and which ones I don’t. Conclusion In summation, in order to become the person I want to be, I need to continuously identify my core competencies. Skills are to be developed according to the actual needs and not merely based on generalities and perceptions. Work-based learning will address this concern by integrating actual experiences and practices in developing new knowledge about the organization. Today, I now know that practice and theories must be merged together (Sill, S. 1958). People can overcome barriers to effective communication. They must first be aware that barriers exist and can cause serious problems. Then they must be willing to invest the effort and time necessary to overcome the barriers. Learning is a lifelong process. If I operate with the assumption that I do not have all the answers or insights, I allow myself to value the different viewpoints, judgments and experiences others may bring. Sometimes I cannot help but think how my life would have turned out had I stayed in the comforts of my home, not taking risks or venturing into the pursuit of my goals. In small ways, I may not even recognize that I do contribute to larger events that happen in this world. If anybody would ask me now if I regret giving up my first degree to pursue counselling, I will answer, â€Å"The sad past led me to a wonderful today. Every bit of failure and pain did not really lead me to regretting anything because in each of those, I learned. And in each of those, I grew – not just as a person for myself but as a person for other people. † And now, I no longer find the question, â€Å"What do I live for? † mushy. I can tell, with chin up, I live for others to appreciate their lives. I do not just exist. I live. I continue to learn through others with high hopes and belief that they also learn from me. As I act, others may take heart and be stirred to action too. But if I waited for things to just happen then in the comforts of my own home, I would have probably be doing things automatically without any awareness devoid of the colorful life I have led ever since I made my choice to be responsible and independent and not sabotage my ability to do things for myself. Part II Portfolio Counselling’s Role in Education The theories learned in the course is revealed as I look at it deeply and as I ponder on the experiences I had about the listening process and being listened to. What comes to be more alive to me now is the issue on Understanding. I learned that to be truly effective, the counsellor must have a thorough understanding of human behavior and be able to apply that understanding to the particular set of problems. For a moment, I knew that my experience with my friend was what I really wanted. This was actually what counsellors do with their clients. And I knew that I had the aptitude for it. In a way, it occurred to me that what I was doing at that moment was like the Person-centered approach which authors Embleton and colleagues (2004) were talking about. At that point I knew the person-centered approach was an effective model for both counselling and psychotherapy especially living in a complex world. (Embleton et al. , 2004). Diagnosis and the hypothesis-generating are critical and inevitable parts of the counsellor’s work. To understand human behavior means to have a set of concepts and theories that help to account for and explain significant human reactions and relate them to experiences. These concepts and principles provide the core for the counsellor’s diagnostic work. Counsellors use their understandings to talk to themselves about their own behavior as well as the concerns, actions, perceptions, emotions and motivations of their clients. With no theory, counsellors have nothing to say in their conversations. Counsellors who comprehend the role that an understanding of human behavior serves in their work, and who recognize the proper function of diagnosis, will work very hard to avoid the pitfalls in this area. It is part of their ethical responsibility. â€Å"How can I help? † As I uttered those words, I remember Higdon’s work on From Counselling Skills to Counsellor: Psychodynamic Approach, because it gave me a new understanding as he began talking. It was as if I was listening with another ear, able to comprehend the emotions behind those words and what he was really saying. (Higdon, 2004). So, I was able to cope with it well. Initially, I was about to call it quits. I had my own issues to attend to. But it dawned on me that his desire to punch the pillows was his desire to remove the cobwebs in his own mind about what he really wanted to pursue. When I really â€Å"heard† him, and listened to him from the heart, I understood that it was his own feelings that he was wrestling with. (Higdon, 2004). Catharsis is often not enough. At some point in the helping process, just as in this example, the counsellor must take advantage of a pause, the completion of some part of the session, or an explicit expectation of the client to help him move to a greater understanding of his anger and eventually to some new action or attitude. Ellis’ proposition that the way we think has a lot to do with the way we feel. Recently, I am reminded of the trend pursued by Meichenbaum (1974), which have very broad applications as a total system of therapy, and is particularly useful with clients whose anger shows righteousness or defensiveness as the dominant component, and many find it by far the most useful long-term approach. These theories became alive as I underwent that experience with my friend. How does it work? Ellis (1966) presents the basic paradigm to clients: (a) A stimulus takes place in your life; (b) you interpreted it in some way; and (c) you have an unpleasant emotional response (anger). Ellis’ Rational Emotive Therapy intervenes in the process at the second step, the interpretation, which, he says, comes from a faulty way of looking at life, a system of illogical thinking. The therapy consists of re-educating the client to think in a healthier, more appropriate way, by helping the client dispute the faulty thinking. This is the point at which many counsellors balk, because to keep at a resistant client with this kind of re-education requires a lot of conviction, ingenuity and persistence. There is a perversity that seems to want to keep the anger. One sees it in the client who resists the helper’s efforts to teach the ways his or her thoughts of being unjustly treated serve to maintain the anger. There comes a time in many helping situations at which the question is appropriate; â€Å"Do you want to give it up? † And the question: â€Å"If you give up the anger, what else do you have to give up? † Sometimes clients will say, â€Å"Yes, I want to give it up. But I can’t† Some clients will say, â€Å"Yes, I want to. Help me figure it out. † Some will say â€Å"I want to stop being so angry, but I don’t want to give it up altogether. † Some will say, â€Å"No. No, I don’t really want to give up. † Regardless of the answer, having the client state it explicitly usually puts the counselling at a stage to consider more accurately and profitably the realities of the client’s aims. If the client asks for help, the counsellor is in good position to offer the resources of his or her ingenuity. If the client wants to stop but not altogether, the counsellor can point out to the client that truth and its implication: â€Å"That is your truth; are you willing to take what comes with it? † If the client does not want to give it at all, the counsellor can take that as a statement of the client’s goals and ask how he can help the client work through the implications of the anger and how to minimize the ill effects of it. In sum, an important precept here aside from Understanding is Client Change. I believe that the ultimate purpose of the counselling experience is to help the client achieve some kind of change that he or she will regard as satisfying. Virtually every significant theory of counselling states that creating some kind of client change in a growth-enhancing direction is the ultimate intended outcome of the counselling experience. Some say overt behavior change is the sine qua non of the experience. Others say that behavior change is simply symptom change; real and lasting change comes when the client develops new perceptions about self, significant others and about life. This is what was glaring from this experience. Client change is often difficult to document. Behavior change, if it occurs, is probably the easiest to observe because it is the most tangible. However, clients may also change their views about certain behaviors that they previously regarded as undesirable—or they may change in the extent to which they experience stress related to an unwanted life situation—or they may change in a variety of other ways that involve internal experiencing. In spite of the difficulties of assessing some kinds of change, it seems that a counsellor who cannot describe the changes that the client ahs undergone has no basis for knowing when counselling has reached and effective conclusion.

Kennedy-Nixon Debates Essays - Richard Nixon,

Kennedy-Nixon Debates In the Presidential Election of 1960 John Fitzgerald Kennedy and Richard Milhouse Nixon were in a series of debates that were different from past debates. The three biggest national television networks arranged for the debate to be televised on all three stations. The Democratic candidate, Senator Kennedy from Massachusetts, and Vice President Nixon both agreed on the televised debates. Each debate was given a subject matter that the candidates agreed to correspond their answers with the subject. The first debate was for the issues concerning domestic questions, the second was centered around the area of foreign policy, and the third and fourth debates were basically a repetition of previous topics. During each debate four news representatives asked questions to each candidate. On September 26, 1960 the first debate took place in Chicago. The moderator was Howard K. Smith, and his job was to introduce the candidates and controlled the question and answer segments of the debates. He instructed the candidates to give their 8 minute opening speech and their three minute closing speech. The first introduced by Smith was Senator Kennedy. Kennedys concept throughout his opening statement was that the world would move in the same direction that the U.S. moved. That was in regard to how the U.S. moved ahead toward freedom. He also stated that the American people should be aware of the communists, Khrushchev in the Soviet Union, the Chinese Communists, how they were on the move and America had to counter and move towards freedom. Kennedy said that America had to be a strong as possible to keep the world moving in the right direction. Another point he made was the lack of American progression, and the way we werent utilizing our natural resources. I believe in effective governmental action. And I think thats the only way the United States is going to maintain its freedom. Its the only way that were going to move ahead. I think we can do a better job. I think were going to have to do a better job if we are going to meet the responsibilities which time and events have placed on us. We cannot turn the job over to anyone else. If the United States fails then the whole cause of freedom fails. (The First Kennedy Nixon Debate, p.2) After Kennedy was finished Smith announced for Vice President Nixon to give his opening statement. Nixon agreed with Kennedy about the U.S. having to move. Nixon compared his thoughts on Communism to a deadly competition, and that the U.S. was ahead and needed to stay that way. He disagreed with Kennedy because Kennedy said that the U.S. had been standing still, and Nixon pointed out that we had been moving. He stated that our gross national product was the highest in the world, that more schools had been built, we had developed more hydroelectric power, and the wages of people had gone up. Nixon said the programs he supported would give all Americans an equal chance for education, better medical care for elders, and more housing. He quickly shot down Kennedys programs and said that with Kennedy the U.S. would quit moving and go stagnate. One of Nixons major points was the spending of each of the political platforms. He showed that with the Democratic platform would spend eighteen billion more dollars a year than what was currently being spent. Nixon and his Republican platform would only spend five billion dollars more than was being spent. In the final part of his opening he said the difference between he and Kennedy was the means of reaching the goals that the two proposed. After the opening statement the questions then were asked by the news correspondents. One question was, Why do you think people should vote for you rather than the Vice President? (The First Kennedy-Nixon Debate, p.4). Kennedy responded by saying that the programs that he advocates compared to the programs advocated by Nixon was the reason that people should vote for him. One question that was posed for Nixon was, Would you tell us please specifically what major proposal you made in the last eight years that have been adopted by the Administration? (The First Kennedy-Nixon Debate, p.5) Nixon answered by giving very specific examples of what recommendations he made to the President about policy making. Then both candidates gave an answer to the question regarding Communism. Kennedy simply said that they needed to watch and be continually alert to what the communists were doing. Nixon agreed and also stated that the way to fight Communism was to

Educational Reform in the State of Florida

Educational Reform in the State of Florida Abstract Educational reform in the state of Florida has proved to be successful as the students’ performance increased in the state. The state ranks 11th in terms of students’ achievements whereas before the reform it was at the bottom of the rating. The so-called achievement gap (i.e. the gap between performance of white and minority students) has decreased, though it still exists.Advertising We will write a custom essay sample on Educational Reform in the State of Florida specifically for you for only $16.05 $11/page Learn More Other states also try to implement the reform. Of course, it is important to remember that to make the initiative successful, government leaders will need to use a comprehensive approach, i.e. the reform should be implemented in full. The Reform in the State of Florida The Educational Reform in the State of Florida was initiated by Jeb Bush, then governor of the state. This reform was implemented in terms of the progra m launched by then President George Bush â€Å"No Child Left Behind† (Anderson, 2011). Notably, the reform has proved to be very successful as the situation has improved considerably. The reform has addressed several issues. Firstly, the state grades schools from A to F. This grading is based on the school’s progress in annual tests in writing, reading, mathematics and science (The Economist, 2012). The schools that receive A get extra funding, whereas if a school grades F twice in four year, students can transfer to another school with a better grade. Apart from this, the third graders who cannot read properly are not any more allowed to the fourth grade. Besides, in terms of the reform teachers whose students pass certain tests receive certain bonuses. Furthermore, the system of vouchers enabled parents to choose among public, private, charter and online schools. Some methods of certification were also implemented. As any other reform, the present initiative has evok ed many debates. There are proponents and those who oppose the initiative. Researchers, educators and officials single out positive as well as negative outcomes of the reform. Arguments for the Reform As far as positive outcomes of the reform are concerned, there are quite many of them. For instance, Florida which was at the bottom of the rating in terms of educational achievement has approached the top ten states (Coutts LaFleur, 2011). Coutts and LaFleur (2011) note that the average performance of Florida’s students is still quite low, and there is still a gap between white and minority students’ performance. However, the researchers admit that the situation in the state has improved significantly (Coutts LaFleur, 2011). Wilson (2012) provides major achievements of the reform. Thus, students with disabilities, Hispanic students and African American studentsAdvertising Looking for essay on public administration? Let's see if we can help you! Get your first p aper with 15% OFF Learn More have made great strides in closing the achievement gap in fourth-grade reading and fourth- and eighth-grade math, improving a grade level each year since 2003 (combined average). (Wilson, 2012, n.p.) The researcher also notes that the achievement gap (though it still exists) has decreased in the state. It goes without saying that education has become more achievable for many people. Minorities and students coming from poor families can obtain higher education. There are lots of grants and other opportunities to go to a college. At this point it is necessary to add that the number of Florida’s students who take various standardized tests has increased (The Economist, 2012). Remarkably, parents can better understand their children’s performance. Parents and students can also choose a school in accordance with the quality of education. On the other hand, schools are also encouraged to improve the services provided. Schools try to have a good grade to remain competitive. Of course, competition is one of the premises for development. Likewise, teachers are also encouraged to give more. If a teacher manages to be inspiring, the students successfully pass exams. These achievements turn into financial benefits for the teacher. This also encourages teachers to try their best to make their students interested in their subject. Undoubtedly, this positively affects the overall performance of students of the state. Arguments against the Reform Irrespective of all positive effects, there are still those who oppose the reform. One of the major arguments of the opponents is that Florida’s students’ average performance is still quite low as the state ranks eleventh (Wilson, 2012). Wilson (2012) claims that this is not quite enough to completely confirm that the reform is 100 per cent effective. Opponents of the reform also state that there is still quite considerable achievement gap between white and mino rity students (Coutts LaFleur, 2011). The opponents admit that the gap is not that high. However, they stress that the reform cannot be regarded as totally effective if the achievement gap still persists. The reform is also criticized for its reliance on standardized tests (Anderson, 2011). It is also mentioned that Jeb Bush slightly increased the fees. However, it is necessary to add that the fees are quite low if compared with the rest of the states. Finally, many people claim that another drawback of the reform is the way Jeb Bush implemented it. Thus, he used quite autocratic ways to make people adopt the new ways.Advertising We will write a custom essay sample on Educational Reform in the State of Florida specifically for you for only $16.05 $11/page Learn More Efforts to Take Admittedly, some arguments against the reform are quite justified. Nonetheless, the reform has proved to be effective. Many states try to implement the reform to improve their e ducational system (Anderson, 2011). However, it is important to be quite careful when implementing the system. In the first place, it is important to remember that any reform is a complex entity. Therefore, it should be implemented in full. It is inappropriate to adopt some ways while ignoring other measures and methods. It can be even more effective if all states implement the reform. Some argue that implementation of the reform needs a lot of money. Nonetheless, government leaders can implement the reform without raising taxes or school fees. Of course, this sphere will still need considerable funding, but it will not require extra funding. The reform presupposes justified allocation of funds. Thus, schools which get grades A and B can obtain extra money, while schools which get C-F will receive only standard funding. More so, it is possible to implement additional measures to help schools performing poorly. Of course, additional bonuses for teachers have fostered quite heated deb ate. Some educators argue that introduction of these bonuses can lead to various violations. More so, some believe that the bonuses may lead to certain kind of disproportion. Admittedly, this is quite a serious issue to address. However, government leaders should not focus on some individuals’ ambitions. It is possible to launch some proficiency tests for teachers. Educators should help teachers who perform poorly. Various training courses should be available for teachers. Therefore, it is possible to note that the educational reform in the state of Florida has proved to be effective. However, it is also important to note that it is far from being completed as educators and government leaders have a lot of issues to address. Reference List Anderson, N. (2011).

Merychippus - Facts and Figures

Merychippus - Facts and Figures Name: Merychippus (Greek for ruminant horse); pronounced MEH-ree-CHIP-us Habitat: Plains of North America Historical Epoch: Late Miocene (17-10 million years ago) Size and Weight: About three feet tall at the shoulder and up to 500 pounds Diet: Plants Distinguishing Characteristics: Large size; recognizably horse-like head; teeth adapted to grazing; vestigial side toes on front and hind feet About Merychippus Merychippus was something of a watershed in equine evolution: this was the first prehistoric horse to bear a marked resemblance to modern horses, although it was slightly bigger (up to three feet high at the shoulder and 500 pounds) and still possessed vestigial toes on either side of its feet (these toes didnt reach all the way to the ground, though, so Merychippus still would have run in a recognizably horselike way).  By the way, the name of this genus, Greek for ruminant horse, is a bit of a mistake; true ruminants have extra stomachs and chew cuds, like cows, and Merychippus was in fact the first true grazing horse, subsisting on the widespread grasses of its North American habitat. The end of the Miocene epoch, about 10 million years ago, marked what paleontologists call the Merychippine radiation: various populations of Merychippus spawned about 20 separate species of late Cenozoic horses, distributed across various genera, including Hipparion, Hippidion and Protohippus, all of these ultimately leading to the modern horse genus Equus. As such, Merychippus probably deserves to be better known than it is today, rather than being considered just one of the innumerable -hippus genera that populated late Cenozoic North America!

The Quest For Wisdom Essay Example | Topics and Well Written Essays - 500 words

The Quest For Wisdom - Essay Example For Pieper, the manner of Liesure contemplation is escorted and saturated by an unforced consciousness for religion, the thoughtful dream of the intellectus, which is not lively but inert, or somewhat amenable, the commotion of the spirit in which it envisages that which it sees freedom. Both the ancients considered intellectus as being previously beyond the globe selected to man. And however it belonged to man, although in one intellect superhuman; the simply human by itself could not satisfy man's powers of understanding, for man, of his very temperament, reaches out beyond the globe of the human. For Plato the finest in him is, even though the understanding which is mainly attribute of the human spirit happens in the form of fraction, never the less there is in it a type of contribution in the uncomplicated knowledge which is appropriate to superior beings, of whom it is consequently said that they hold the sense of religious visualization. But for Pieper, the aptitude to detain t he religious conscience in the similar way that our eye captures illumination or our ear sound. And is the noblest form of human existence. But awareness in philosophy is focussed upon the entire of being and begins with a scholarly instinct of being, as such rooted in the wisdom of touch; this is what is identical on both the authors.

Professional Development of Nurses Essay Example for Free

Professional Development of Nurses Essay In 2008, the Institute of Medicine (IOM) partnered with the Robert Wood Johnson Foundation (RWJF) to form an initiative on the future of nursing. The RWJF is an independent organization that focuses on healthcare innovations and programs such as childhood obesity, health coverage, and public health. The IOM is a non-government resource that assists the government and private agencies in making informed decisions about healthcare issues (ISNA bulletin, 2011, p. 11). This 2 year study focused on the current state of healthcare, specifically nursing, and provided recommendations to improve the nursing profession and enhance the infrastructure of healthcare. Key points were safety, technology, and interdisciplinary collaboration of practice. The study focused on nursing education, practice, and nursing’s role of leadership (Committee on the Robert Wood Johnson Foundation Initiative on the Future of Nursing, at the Institute of Medicine [RWJF], 2011). The focus on education was primarily driven to advance the educational system and to further advance nursing care in the changing face of healthcare reforms. The study showed that nurses have a significant impact in healthcare, with more than 3 million members; they are posed to generate a large role in the reform of the healthcare system (Committee on the Robert Wood Johnson Foundation Initiative on the Future of Nursing, at the Institute of Medicine [RWJF], 2011). The IOM strives to achieve higher levels of education through improved educational systems. Nurses are encouraged to practice to the full extent of their education and training. The IOM initiative is promoting removal of the barriers that are in place regarding scopes of practice for advanced practice nurses and to standardize the scope of practice delineations across state lines. The report recommends support of nursing education and programs expanded to graduate more upper level nurses who will then focus on becoming educators. The goal of the IOM is to have 80% more baccalaureate prepared nurses by 2020. By increasing the number of nursing programs that are now in place and changing those from purely traditional learning to a hybrid of traditional and innovative or online programs more nurses will graduate with higher degrees. Intensifying the traditional curriculum to include interprofessional collaboration, communication, and systems thinking helps to encourage higher level thinking and superior leadership skills. Additionally encouraging nurses to engage in lifelong learning to retain and renew competencies is very important; the competencies should be relative to the knowledge, experience, and practice of the nurse. Another part of the education process is the implementation of nurse residency programs. These programs are important because it takes time and experience for a nurse to become fully prepared to be functional in the acute care setting and these new opportunities will encourage the nurses to stay at the institution. This IOM report has a tremendous impact on nursing practice, particularly in primary care with the focus being on increasing nursing education to provide higher quality care for the patients. Keeping up with facility and national competencies is important to ensure that the nurse’s practice is up to date and current. Improved technology also increases the nurse’s efficiency and the amount of time that the nurse is able to spend with their patients. Additionally, this helps with the education of the patient because when the nurse is able to spend more time with the patient more effective teaching is done. Patient safety is one of the most important parts of nu rsing and by utilizing education as well as technology nurses are able to prevent critical errors and maintain patient safety more effectively. With the new Patient Protection and Affordable Care Act (PPACA) traditional healthcare is evolving to patient centered care delivered in the community rather than in the acute care setting. Advanced practice nurses will have a bigger â€Å"voice† in the community and an enormous impact on healthcare. This will impact me in my nursing facility because as I am better educated and up to date on my competencies, my patients are safer, I am utilizing the most recent technology in caring for them, and therefore providing them the best and safest care. The IOM report is describing an ideal world where nurses are significant as leaders, in a partnership with physicians and other healthcare professionals, in redesigning the healthcare system. To accomplish this reform, nurses must be educated as leaders by focusing on communication, professionalism, interprofessional collaboration and decision making (ISNA bulletin, 2011, p. 12). The nurse should be actively involved in identifying problems, collaborating with the physicians to seek solutions, and be committed to providing safe and effective healthcare to the patients and community. Leadership also plays an active role in policy making, institutional model development, and improving work processes. Nurses, with their backgrounds in patient care, have a unique understanding of patient well-being, institutional policies, and flow of the healthcare team which helps them to be on the forefront of change. In closing, the IOM report is a detailed description of recommendations that describe how nurses can and should be actively participating in the healthcare reform. It is time for a change and nurses have the opportunity and responsibility to participate in these transformational changes. Education, leadership, changes in nursing practice, and collaboration of the healthcare team are the keys to change.

Basketball :: essays research papers

Basketball Basketball is a great game that is one of the most popular in America. In this sport you have to have good aim to shoot, good jumping skills to rebound, you have to be quick, and also have good ball handling skills. In a real game there are only five players on the court, referees, foul outs, and rules like no running with the ball, no fouling, out of bounds and no running over the other teams players on offense. I really enjoy playing this game and I practice a lot outside on my court and play for P.A.L in the winter. I think I am a pretty good player and dream of playing for the NBA one day. Next year I'm going to play varsity for our school instead of wrestling and try my best to help the team win. If I try really hard and practice everyday I could be an extremely good player. I usually play with my friends after school for fun or just to play around and have a good time, practice on my own to practice things I need work on, or practice with my dad and let him give me some pointers. I love watching basketball games on TV and usually watch the Knicks play. Out of all of the 28 teams in the NBA my favorite teams from best to least favorite are the New York Knicks with Patrick Ewing, Larry Johnson, John Starks, Charlie Ward, Chris Childs, Charles Oakly, and Allen Houston. Then I like the Charlotte Hornets with Anthony Mason, Tyrone Bouges, Glenn Rice, Gladie Divac, and Curry. My third favorite team is the Seattle Super Sonics with Shawn Kemp, Gary Payton, Schremph, and Perdue. My fourth and final favorite team is the Orlando Magic with my favorite player Anfernee Hardaway, Horris Grant, and Nick Anderson. My three favorite players in the NBA are: 1)Anfernee Hardaway/ nickname: "Penny" 2)Larry Johnson/nickname: "Grandma" 3)Shawn Kemp/nickname: "Rainman" These players have a lot of talent and I enjoy watching them play. For instance Anfernee is a leader for the team and has good passes, good dribbling, and good shooting skills. While Larry Johnson has good rebounding, pretty good shooting, and good dunking skills. Last but not least Shawn Kemp who has great rebounding and spectacular dunking skills including fancy dunks and great allyoops. I think basketball is a great sport and that it will continue to be

Imperialism Within the Heart of Darkness Essay

A phenomenon, The Heart of Darkness, is a classic novel by Joseph Conrad, who reward individuals with their dark nature. The darkness that the characters face within themselves is the anchor towards the main theme of imperialism. Native Africans, around the early 1900s, were victims of imperialism in the novel. The Europeans saw themselves as prodigies and felt everyone redundant wanted to be like them for they perceived themselves as extraordinary. The Europeans thought so highly of themselves that they wanted to civilize what they perceived the Native Africans to be—savages. Ironically, the process of civilization became imperialism, and the Europeans were the definition of savage while the Native Africans perceived themselves as civilized. Conrad strategically evolved this theme with the narrative of his novel and the various tones and symbols he used revolving around imperialism. These literary strategies and devices led readers to understand the secret of the darkness in the European heart, which was European imperialism. Entering the novel, Conrad has the narrator explain: â€Å"It was difficult to realize that his (the Director of Companies) work was not out there in the luminous estuary, but behind him within the brooding gloom† (Conrad 1). Here, Conrad’s use of pathetic fallacy forewarns his audience from the very beginning that the European companies are working in an unlawful matter (Shmoop.com). The Europeans are vague, and the fact they are working within the dark makes them more malicious. This behaviour leads to having an imperialistic nature because in order to have the desire to take over a race, in this case the Native Africans, one needs to already be in tuned with their dark nature. Conrad includes a second narrator, the protagonist to The Heart of Darkness, who makes a remark to the beautiful sunset over the Thames river in London saying: â€Å"‘And this also,’ said Marlow suddenly, ‘has been one of the dark places of the earth’† (1). For Marlow to reveal a beautiful image of England as being â€Å"one of the dark places of the earth† (1), tells individuals that the Europeans are morally corrupt (Shmoop.com). For the Europeans to do the morally bankrupt task of ‘civilizing’ the Native Africans, whom they acclaimed them to be the morally corrupt, only infers that the Europeans committed an offence to be proven guilty of the false accusation. The offence being imperialism; to be remarked as morally corrupt suggests that they encountered savage-like behaviours against the Native Africans. Therefore, through the narrative at the very beginning of the novel, one can infer that imperialism evolves as the Europeans are justified to have the dark nature to civilize a nation. Conrad sets the tone by casting a â€Å"mournful gloom† (Conrad 1) atop London. â€Å"The air was dark above Gravesend and farther back still seems condensed into a mournful gloom†¦over the biggest, and the greatest, town on earth† (1). This infers that darkness is bestowed on the purity of the â€Å"greatest town on earth† (1). Conrad decides to incorporate a mood-shifter to infer that the Europeans are victims to a form of darkness and that negative events will follow. Since their goal in the novel is to civilize the Native Africans, it is forewarned that they will try to civilize them with dark power leading to imperialism. Another area where Conrad sets a dark, gloomy mood would be when Marlow talks about humans being drawn to their madness hidden within their darkest self. â€Å"The fascination of the abomination—you know. Imagine the growing regrets, the longing to escape, the powerless disgust, the surrender, the hate† (1). Marlow’s words bring out the theme of curiosity; the curiosity of what lies within the darkest areas of an individual. This quote states that humans are fascinated with their abomination because they have not yet experienced it; but once they have, they feel powerless and yearn to escape, but the abomination overtakes them. This certain curiosity of evil and darkness is what reigns over Europe. They are so curious of their own darkness that they themselves get lost within it and become the culprits of imperialism. Thus, through the moods and tones Conrad implants at the very beginning of his novel, he brings forth the coming of events which evolve into the realization of imperialism. Conrad uses symbolism in The Heart of Darkness to heighten the approach towards imperialism. For example, the reader’s encounter with the Accountant of the ivory trading Company in the outer region of Africa. Marlow describes him as an elegant dresser: â€Å"†¦I met a white man, in such an unexpected elegance of get-up that in the first moment I took him for a sort of vision† (16). Here, Marlow enters the beginning of his journey to the heart of Africa, and seeing the Accountant dress beautifully makes him seem like some kind of â€Å"miracle† (16) since their setting at the particular moment is in contrast. The Accountant symbolizes the Company and its excellence, professionalism, and perfection. Despite the blazing heat and his surroundings of poverty, he always dresses well. This is the professionalism of the Company. The fact he immerses himself within his accounting books represents the Company’s excellence and perfection. But although he is a man of perfection, the fact that the sight of suffering Native Africans distracts him and causes mistakes in his work, this symbolizes the room for error in the Company. This is an approach towards imperialism because wrong and unjust actions are seen as ‘errors’ in which the Company is a culprit of. Also, the symbolization of flies and its representation of death heighten the approach to imperialism as well. Ever since the devil is nicknamed, the Lord of the Flies, flies have represented death (Shmoop.com). Flies are seen in parts one and three when slaves, as well as a man named Kurtz, have their life taken away. Since the flies are associated with the devil, this implies that the devil, or the darkness that overcomes Europeans, have a connection with the deaths of human lives. Therefore, Conrad uses different symbols such as the spotless attire of the Accountant and the devil’s flies to inform readers about the imperialistic actions of Europeans. Joseph Conrad uses narrative schemes, sets moods and tones, as well as involves symbolism to approach his major theme of imperialism. He takes readers to the darkness of the human soul, a space which reigns in every single human being. This allows the individuals to take note that they can be greatly influenced by their darkness: creating the ability to carry out unjust behaviours, such as committing imperialistic actions. Therefore, this novel is a great commentary to human error, such as being past culprits of imperialism, and brings awareness to human morality. Works Cited: â€Å"Heart of Darkness.† Shmoop.

Wing evolution has been a highly debated topic in insects. Wings play a crucial role for insects since they are used to assist with collecting food, migration, fleeing from predators, and many other activities. There are three main theories that have been thoroughly researched to help explain the evolution of wings. These theories include the parental origin of wings, the tracheal gill theory, and the exit-endive theory. The parental origin of wings hypothesis states that wings developed from parental lobes.When insects fell on the ground, nobles first acted like a racquet so the insect can land swiftly on its feet and scurry away from predators. As nobles grew larger they developed from gliders into wings. The main evidence behind this theory is the presence of broad thoracic onto and wing like pornographic lobes on fossils Of Ephemerals, Plenipotentiary and Appropriate that show venation and articulation (Whitfield 324).The tracheal gill hypothesis postulates that wings developed f rom tracheae gills since both were thin, membranous and mobile. Gills first started off for being used for breathing in oxygen, then used as fins to promote locomotion, ND finally modified the spiracles which reduced water loss to permit gliding which eventually turned into flying. Wigglers supported this theory by stating that wings and legs could be found in the thorax if it was originated by exits (Whitfield 325).The exit-endive hypothesis proposes Koala-Peck's theory about wings developed from exits that were found on many leg bases of early insects. Later, it was found that those insects also had endives. This theory was us ported by the fact that wings are originated from a structural feature that already had the necessary muscles, tendons and appendages of insects. This was later proven by the dismissal of Montana's theory that insect's legs are different than other arthropods legs (Whitfield 326). Live that the exit-endive theory seems the most plausible since it is most lik ely that wings emerged from endives and exits since those features were already present in insects. Also this theory has the most support compared to the other two theories and there are not many who oppose this theory. For the tracheal gill hypothesis to be true, the invasion of land would have to happen twice to accommodate for both insects with wings and without wings, Journal Entry On the news there was a story about a new museum being opened up in the American South that depicts the belief in creationism instead of evolution. Basically, this museum depicts human beings being created by God alongside dinosaurs and does not recognize that the Earth is older than 10,000 years old. Many people are protesting the museum because they feel that it perpetuates a religious belief as science and that it cannot be considered truthful and shouldn’t be viewed as a museum. I feel that this article is important because it shows how different religions and cultures can clash and different viewpoints can cause conflict amongst people. This news story, that I saw on CNN, has a central theme revolving around the fact that religion and science can cause conflict in a community. This was very interesting because of the fact this is the first museum to depict creationism as a science and because it is making such an impact in the community, with so many people protesting it because they feel it shouldn’t be marketed as science but as religion. This is important because both religious and non-religious people need to live side by side in our communities and it raises questions about how this can happen in terms of their beliefs about creation versus evolution, and how this aspect can help shape each of us depending on our upbringing and personal beliefs. Journal Entry # 2 The article â€Å"Trial set to begin in Mississippi civil rights-era case† by Jerry Mitchell appeared the USA Today on May 24, 2007 and deals with the case of a man who is facing charges for killing two African-American teenagers in 1964. This is an interesting article because it shows how much different our culture is today from the culture of the civil rights-era United States. Back then, white men were not punished for killing blacks, but today our culture and society have changed enough that we can look to make the past right to make a better foundation for the future. In the past few years there has been a push in Mississippi to bring to justice former klansmen and other racists who killed civil rights workers and African-Americans during a time and in a place where discrimination was so abundant that no one would convict them. This case is one of these, and is an interesting look at how the justice system can be corrupt and yet, today, we can try to make things right. This is so important today because of the issue of racism that is still there below the surface in many instances. Journal Entry # 3 The article â€Å"Gold Star wives help a new generation of war widows† that appeared on CNN.com on May 26, 2007 is an interesting look at the way that our own suffering can be a basis for helping others in similar situations. The article deals with the social issue of war and how it affects not only the people in the midst of the war but the wives, husbands, and children that are left behind by the men and women who die in the war in Iraq. This article is about a woman named Marie Speer who lost her husband in WWII and how she founded this organization called Gold Star Wives, which was established to help war widows in many various ways, from friendship and compassion, to helping lobby for benefits for the wives and husbands of those lost in the war. This story is applicable to the real world because of how our culture has been affected by the war in Iraq and how society looks at this conflict and the people affected by it. This is interesting because it shows how Americans are coming together and using their own experiences to help others and try to bring them through the pain of loss and grief. This is so important today because of the loss of connection many of us have in relation to each other. For example, many people cannot connect with people of other generations but in this article it shows how a WWII war widow has so much in common with a widow of a soldier in Iraq. It shows how we can all connect with each other on some level, and this is important in a country that lacks that. Journal Entry # 4 On Glenn Beck there was a story about how Rev. Al Sharpton, who had just finished recently lobbying to get Don Imus fired for his racial remarks regarding the Rutgers basketball team, had said something discriminatory about Mitt Romney’s Mormon religion. This is an important issue because so many people can look at this and see that so many people have underlying racism or discrimination about other people’s race, ethnicity, or religion. This is an aspect of our culture that has shaped each of us, depending on where we grew up and who raised us, as well as what our own experiences have shown or taught us. The central theme of this news story is that sometimes we can see discrimination within others more than we can within ourselves and that this needs to be an issue that is raised to each of us when it comes to light. This is very interesting in one aspect because those who thought that the media made too much out of the comments by Imus could say that Sharpton had no right to complain because he then becomes embroiled in his own scandal, but others can look at it from a different perspective and say that comments about race and religion are completely different and shouldn’t be equally compared. This is so important in our politically correct society because it begs an answer to the question about what is discrimination and when does free speech cross the line, and how has society viewed free speech and political correctness. Journal Entry # 5 The article â€Å"The First Steps† by Alex Tresniowski, et al, appears in the May 7, 2007 issue of People Magazine and is a look at the healing process that is happening at the Virginia Tech campus in Blacksburg, Virginia following the massacre that killed 33 students in Norris Hall on April 16th. This article is unlike many of the others because instead of dealing with the dark, brooding gunman or all of the mistakes and issues that led up to the shooting, it deals with how the students affected will take steps to heal and help create a better environment for all students on campus. This article was interesting to me because it was not just another doom and gloom article about the tragedy but point out what was being done right by the Virginia Tech students, faculty, and campus administrators to help the college heal. It was interesting to read the stories about these heroes and the terrible trauma that they went through during the massacre. It was also interesting to learn about how the community and society has come together to help create a safer environment at colleges and to help these students through the tragedy. Violence has become such a huge social problem in our society and this issue was made even more glaring by this particular school shooting. The article’s look at the counseling being offered, the changes in the college, and most especially the way that the community, parents, and students are all reaching out to each other as a means of healing is incredible. It also shows how they are hoping to eliminate loners and outcasts like the shooter by reaching out to their fellow classmates in need. Instead of dwelling on the bad, they are looking for something positive to come out of the tragedy.                Journal Entry Wing evolution has been a highly debated topic in insects.

Effect of atenolol on contractile function Essays

Effect of atenolol on contractile function Essays Effect of atenolol on contractile function Essay Effect of atenolol on contractile function Essay Consequence of Tenormin on contractile map during ischaemia and reperfusion in the rat isolated perfused bosom Purpose:?-blockers are thought to exercise good effects on the ischaemic bosom. We examine the consequence of Tenormin, a selective ?1 adversary, on contractile map at low ( 10 µM ) and high ( 50 µM ) concentrations in the stray rat Black Marias. Methods:Isolated rat Black Marias ( n=8 in each group ) were perfused with Krebs solution for 5-min. They were so perfused with test solution: controls incorporating Krebs, or selective Tenormin ( 10 µM ) or high concentration of Tenormin ( 50 µM ) . After 10-min, the Black Marias were subjected to 30-min of planetary ischaemia ( zero-flow ) followed by reperfusion with the same trial solution as earlier. The starling curves were constructed prior to and after ischemia. Consequences:No important alterations in maximal ischemic contracture and clip to half maximum contracture were seen in Black Marias pre-treated with test solutions. LVEDP was increased by 4-fold in control for Tenormin ( 10 µM ) and by 12-fold in Black Marias treated with control for Tenormin ( 50 µM ) , 5-min after reperfusion, comparing to pre-ischemic values ( P lt ; 0.05 for control for atenolol 10 µM vs. control for atenolol 50 µM ) . No alterations in coronary flow or bosom rate were observed between groups at baseline and during reperfusion. LVEDP was quickly increased from 2.6 ±1.3 mmHg to 28.6 ±9.0 mmHg in control for Tenormin ( 50 µM ) and from 4.0 ±1.6 mmHg to 27.3 ±7.6 mmHg with Tenormin ( 50 µM ) , in the starling curves constructed with 60 µl of increase in the balloon, prior to the ischemia and after reperfusion ( P lt ; 0.05 for pre-ischaemic perfusion vs. post-ischaemic reperfusion ) . Decisions:The present survey shows that Tenormin has no cardioprotective effects on contractile map during ischemia and reperfusion in stray rat Black Marias. Introduction ?-blockers have been widely shown to hold cardioprotective effects on ischaemia and hypoxic Black Marias, including betterment in ventricular map, and ensuing in a reduced mortality rate in ischaemic bosom disease patients ( Wallace et al. , 1998 ) . Although, the exact mechanisms by which cardioprotective agents act are non yet to the full understood, ? blockers are thought to exercise good effects on the ischaemic bosom by take downing myocardial O ingestion as a effect of decreased contractility and bosom rate ( HR ) . The consequence of ?-adrenergic receptor adversary, Tenormin, on the contractile map in the stray bosom is still a controversial subject of research. Several surveies have shown that Tenormin does non protect against ischaemia-reperfusion in a theoretical account of an stray perfused bosom exposed to planetary or no-flow ischemia ( Singh et al. , 1995 ; Harada et al. , 1981 ) . However, on the other terminal of the spectrum there have been studies bespeaking that an ischemic period of longer than 3-4 min induces important release ( 2700pmol/g bosom ) of endogenous catelchoamines ( norepinephrine ) in the stray rate bosom ( Wollenberger and Shabab, 1965 ) . In add-on, an flood of catecholamines during the reperfusion period has besides been reported, which is thought to be a consequence of washout of norepinephrine antecedently released from the sympathetic nervousnesss or due to a reperfsion activated release ( SchSmig et al. , 1984 ; Carlsson et Al 1985 ) . It is suggested that cate cholamines mediates contractility of the cardiac musculus. These agents work by triping ?-adrenergic receptors, taking to the activation of adenylyl cyclase, which so elevates the degrees of a secondary courier camp. Increased camp activates protein kinase A ( PKA ) , which causes increased entry of Ca into the cell, ensuing in positive inotropy ( increased contractility ) in the cardiac musculus. The positive inotropic consequence due to high degrees of endogenous catecholamine should be hence attenuated by the usage of selective concentration of ?1-adrenoceptor adversary, Tenormin. In order to prove the counter consequence of Tenormin, we use a selective concentration of Tenormin ( 10 µM ) on a normal operation rat bosom and in a theoretical account in of 30-min of globally ischemic induced rat bosom followed by 10-min of reperfusion. Since the release of endogenous catecholamines upon ischaemia is controversial, we besides used a high concentration of Tenormin ( 50 µM ) to find counter action of non-selective atenolol dose on receptors other than ?1-adrenoceptors, and to see if it enhances recovery in contractile map upon ischemia. The Langendorff scenes were used in this experiment as it is a widely used readying which provides valuable information on left ventricular systolic and diastolic force per unit areas and their derived functions in Black Marias, subjected to ischemia ( Skrzypiec-Spring et al. , 2007 ) Methods Anaesthesia, bosom deletion and perfusion All experiments were carried out in understanding with the United Kingdom Home Office Guide on the Operation of the Animals ( Scientific Procedures ) Act 1986. Rats ( male Wistar strain ; Sigma chemicals U.K. , 230-280g ; n=8 in each group ) were anaesthetised with Nembutal by an intraperitoneal injection ( 60mg/kg ) . An endovenous injection of Lipo-Hepin ( 300 I.U ) , an decoagulant, was given to forestall the formation of thrombi. Heartss were so excised: foremost, the stop was accessed by a transabdominal scratch and cut carefully to expose the thoracic pit. The thorax was opened by a bilateral scratch along the lower border of the last to first ribs and the pectoral coop was so reflected over the animate being s caput, thereby exposing the bosom. The bosom was so cupped between the fingers ( in order to avoid bruise hurt ) and lifted somewhat before incising the aorta, vena cava and pneumonic vass. To avoid any ischaemic hurt, after deletion, Black Marias were instantly immersed in ice-cold perfusion solution ( 4 °C ) incorporating following composing ( in millimeter ) : NaClA 118.5, NaHCO3 25.0, KCl 3.0, MgSO4 1.2, NaH2PO4 1.2, gluc ose 11.1, CaCl2 1.4, followed by the canulation of the aorta and the bosom was so perfused retrogradely down the aorta, harmonizing to the Langendorff manner ( 1895 ) with a changeless hydrostatic force per unit area equivalent to 100 cmH2O, and perfusion solutions aerated with a gas mixture of 95 % O2 + 5 % CO2, delivered at pH of 7.4 at 37 °C. A changeless temperature 37 °C of the perfusate was maintained with a heat money changer ( Techne Circulators C85-A, UK ) . Perfusion solutions were non recirculated. Measurement of left ventricular force per unit area utilizing intraventricular balloons After remotion of the left atrial extremity, a fluid-filled compliant balloon was attached via a blunt-ended acerate leaf ( 21 gage ) and a catheter to a force per unit area transducer, which was carefully inserted into the left ventricular pit via the mitral valve. The balloon was used to find the contractile activity of the bosom: the measuring of left ventricular systolic ( LVEDP ) and diastolic force per unit areas and ( by difference ) left ventricular developed force per unit area ( LVDP ) and the bosom rate. The balloon was ab initio inflated with H2O from a microsyringe until a developed force per unit area of 100 mmHg was obtained so farther volume was added to bring forth starling curve. The force per unit area transducer was connected to a biological recording system equipped with amplifier ( PowerLab 4/25, AD Instruments ) . Experimental protocol The stableness and duplicability of each readying was monitored by mensurating the baseline contractile map during the first 15-min of aerophilic perfusion. Heartss were perfused for an initial 5-min with a standard Krebs solution, followed by another 10-min perfusion with one of the several trial solutions, which were perfusion solutions incorporating Tenormin ( 10 µM ) , control for Tenormin ( 10 µM ) , atenolol ( 50 µM ) and control for Tenormin ( 50 µM ) . Standard Krebs solution was switched to one of the trial solution in a randomized blinded mode, in order to avoid prejudice. Blinding was achieved by coding the solutions, with the codification unknown to the person. Ethanol ( 0.05 % v/v ) was moving as a drug vehicle for Krebs solution, and added to all the perfusion solutions to extinguish vehicle as a beginning of discrepancy. The relationship between the intraventricular volume and the force per unit area was studied as described by Otto Frank in 1895, the Frank-Starling jurisprudence of the bosom ( Frank et al. , 1895 ) . The balloon was deflated to the nothing volume, prior to the building of starling curves, and so increasingly inflated by adding 0.02ml increases to the balloon ( 30s at each increase ) , until a diastolic force per unit area of 20 mmHg could be observed, during which clip systolic, diastolic, and developed force per unit area, bosom rate and coronary flow were monitored. The balloon was deflated back to zero volume. After baseline experiments, the Black Marias were made globally ischemic ( zero-flow ischemia ) for 30-min by clamping off the aortal flow. During ischemia, Black Marias were immersed in Krebs solution and temperature was recorded with a thermometer. Heartss were so reperfused for 10-min under the same conditions of baseline ; therefore the intraventricular balloon was deflated sufficiently to re-establish a developed force per unit area of 100 mmHg. Another starling curve was so constructed via the same intraventricular balloon method and the appropriate measurings were recorded. Measurement of coronary flow The measuring of coronary flow was performed by mensurating timed volumes of perfusate run outing out of the right atrium. Flow was calculated as ml/min/g of wet tissue, therefore taking into history any differences in weight between single Black Marias. Drugs All the drugs were obtained from Sigma Chemical Co. ( Dorset, UK ) . Atenolol was diluted in Krebs solution, in order to accomplish appropriate concentrations ( 10 µM and 50 µM ) . Statisticss Datas are expressed as mean ±SEM. Two-tailed t-test was performed presuming two-sample equal discrepancy ( homoscedastic ) . A difference was considered to be statistically important when P lt ; 0.05. Consequences Development of ischaemic contracture during 30 min of planetary Ischemia Maximal ischemic contracture was determined by mensurating the maximal rise in diastolic force per unit area from the baseline point. Time to onset 50 % of the maximum contracture was besides found, which is an accurate step to measure ischemia-induced diastolic disfunction ( Fig.1 ) . Conventional representation of development of ischemic contracture ( during 30 min of planetary ischemia ) for an single hint of Tenormin ( 10 µM ) in the rat isolated bosom. A rapid rise in LVEDP was noticed shortly after the initiation of planetary ischemia. Owing to the fact that volume in the balloon was kept changeless therefore any addition in LVEDP was stand foring contracture of the stray rat bosom. Function during the ischemia was non the Centre of attending here and merely certain effects of the intercessions were noted. There were no important differences, in footings of the maximum contracture and clip to achieve 50 % of maximal contracture, between the two control groups and the comparative values of Tenormin ( 10 µM ) and Tenormin ( 50 µM ) group ( Fig.2 ) . The clip to half-maximal contracture was 20.8 ±4.3 min with a peak contracture of 30.8 ±6.1 mmHg in the Black Marias treated with control for Tenormin ( 10 µM ) . No important consequence of planetary ischaemic on contracture development was seen in Black Marias treated with Tenormin ( 10 µM ) i.e. , the clip to half maximal contracture occurred at 16.0 ±2.7 min and peak contracture at 38 ±7.2 mmHg. This was besides the instance for Black Marias perfused with high concentration of Tenormin ( 50 µM ) , ensuing in peak contracture of 41.3 ±4.5 mmHg and the clip to half maximum contracture of 14.4 ±2.2 min, in comparing to the matching values of control for high concentration in which peak contracture and half-maximal contracture were delayed to 43.0 ±7.6 mmHg and 15.8 ±2.4 min, severally. Consequence of Tenormin ( 10 µM ) and Tenormin ( 50 µM ) on extremum ischaemic contracture development and clip to half-maximal ischemic contracture. Datas are mean ±S.E.M. There were no important differences between groups. n=8 in each group. Postischaemic profile for: ( a ) terminal diastolic force per unit area, ( B ) developed force per unit area, ( degree Celsius ) bosom rate and ( vitamin D ) coronary flow in stray rate Black Marias treated with Tenormin ( 10 µM ) , control for Tenormin ( 10 µM ) , atenolol ( 50 µM ) and control for Tenormin ( 50 µM ) . Baseline represents values taken 1-min anterior to the ischemia ; 5 and 9 min represents reperfusion clip points after 30-min of planetary ischemia. Valuess are average  ± SEM ; n=8 in each group. *P lt ; 0.05 ( control for atenolol 10 µM vs. control for atenolol 50 µM ) . Postischaemic recovery of terminal diastolic force per unit area, developed force per unit area, bosom rate and coronary flow LVEDP rose by 4-fold in control for Tenormin ( 10 µM ) 5-min after reperfusion comparing with the values before the oncoming of ischemia ( Fig.2 ) . In contrast, a rapid addition by 12-folds was noticed in Black Marias treated with control for Tenormin ( 50 µM ) ( P lt ; 0.05 control for atenolol 10 µM vs. control for atenolol 50 µM ) . LVDP fell down by 21 % and 57 % in Black Marias treated with controls for Tenormin ( 10 µM and 50 µM, severally ) 5-min after the oncoming of reperfusion comparing with the values before the oncoming of ischemia. This clearly shows that post-ischaemic recovery of LVDP was hapless in Black Marias treated with control solutions. The corresponding decrease in LVDP by a little border of 4 % and 13 % in Black Marias treated Tenormin ( 10 µM ) and Tenormin ( 50 µM ) severally, may be a small surprising but such values are non extremely important in comparing to the controls, hence no important betterment in post-ischaemic LVDP recovery is observed. No important alterations in coronary flow were seen between groups at baseline. During reperfusion, no damage in the coronary flow was apparent in the Black Marias treated with Tenormin ( 10 µM ) and high Tenormin ( 50 µM ) in comparing to the comparative values for control groups. Besides, no important difference in the bosom rate was found at the baseline and at the terminal of 10-min reperfusion between any of the groups. With 60 µM of increase in the balloon, there was a significant rise in the diastolic force per unit area for the starling curve taken prior to the oncoming of ischemic in comparing with values taken 30-min after the ischemia, for Black Marias treated with Tenormin ( 50 µM ) , and control for Tenormin ( 50 µM ) . The diastolic force per unit area drastically increased from 2.6 ±1.3 mmHg to 28.6 ±9.0 mmHg ( P lt ; 0.05 ) for Black Marias treated with control for Tenormin ( 50 µM ) and a corresponding rise from 4.0 ±1.6 mmHg to 27.3 ±7.6 mmHg ( P lt ; 0.05 ) in Tenormin ( 50 µM ) treated Black Marias. This clearly indicates a presence of diastolic disfunction. No important rise in diastolic force per unit area was seen in Black Marias treated with control for Tenormin ( 10 µM ) and Tenormin ( 10 µM ) . Relationship between diastolic force per unit areas obtained with 60 µM of increase in the balloon prior to the oncoming of 30 min ischemic and postischaemia in the rat isolated bosom treated perused with the trial solutions. Datas are mean ±S.E.M. ( *P lt ; 0.05 pre-ischaemic perfusion vs. post-ischaemic reperfusion ) . n=8 in each group. Developed force per unit area dropped down by 21 % and 28 % in Black Marias treated with Tenormin ( 10 µM ) and Tenormin ( 50 µM ) , severally, for the values taken before the oncoming of ischemia and after 30 min of ishaemic period with 60 µM of increase in the balloon. In contrast, a little rise in developed force per unit area by 9 % and 24 % in Black Marias treated with control for Tenormin ( 10 µM ) and control for Tenormin ( 50 µM ) . In both instances, an addition or lessening in developed force per unit area was non extremely important. Discussions A rise in ischaemic contracture was noticed in the current survey, which is thought to be due to depletion of ATP production via glycolytic tract ( anaerobiotic glycolysis ) instead than entire cellular ATP content ( Kingsley et al. , 1991 ) . It is besides believed that an early contracture may hold Ca constituent as intracellular free Ca ions are reported as a cardinal go-between of ischemic hurt ( Tani M. , 1990 ) . In order to understate ischaemic hurt we used a recommended concentration of Ca ( 1.4mmol/L ) in the perfused solutions ( Fiona et al. , 2003 ) . No decrease in the maximal-ischemic contracture was seen in Black Marias pre-treated with atenolol therefore Tenormin did non hold any contraceptive consequence on ischemic contracture development. This was farther apparent by no protraction of the clip to half maximum contracture, in the presence of Tenormin, proposing that ischaemic hurt was non reversed in this instance. An expected ague rise in ventricular diastolic force per unit area and a diminution in developed force per unit area was detected in all ischemic-subjected Black Marias ( Porter T. , 1895 ) . Atenolol did non do important postischaemic recovery in LVPD and LVEDP during reperfusion. Although, Black Marias treated with control for Tenormin ( 50 µM ) had a rapid rise in LVEDP in comparing to the Black Marias treated with control for Tenormin ( 10 µM ) such difference could be due to variableness in the consequences as experiment was carried out in two different yearss and environmental conditions may hold influenced consequences to a certain extent. In add-on, the dependability of consequences is besides questionable as few values could non be taken during the experiments due to an oncoming of ventricular fibrillation taking to inaccurate average values. No major alterations in bosom rate and coronary flow were seen between groups at baseline and 10 min after reperfusion in Black Marias subjected to ischaemia. Changes in coronary flow are usually accompanied by alterations in LVDP ; hence no important alterations in coronary flow confirm the cogency of LVDP step as antecedently described. There was a mark of diastolic disfunction as evident in the starling curve constructed prior to the oncoming of ischemic in comparing to the values taken after reperfusion. This diastolic disfunction further indicates no mediated cardioprotective effects of Tenormin as preconditioning, and reperfusion with Tenormin did non rarefy contractile disfunction. In drumhead the present survey shows that both low ( 10 µM ) and high ( 50 µM ) doses of Tenormin did non hold any cardioprotective effects on ischaemic/reperfusion hurt in stray rat Black Marias. The effectivity of ?-adrenoceptor encirclement in the ischaemic reperfused stray Black Marias has been demonstrated in the past surveies. Lu et al reported that pretreatment with Tenormin did non demo betterment in postischemic recovery in the stray coney Black Marias ( Lu et al. , 1990 ) . They used 10 mg/l of Tenormin in the Black Marias subjected to 25-min ischemia, followed by 30 min of reperfusion. The average functional recovery of aortal flow was merely 6 % in Black Marias treated with a control solution and no important rise in aortal flow recovery could be observed with Tenormin treated Black Marias. In the bosom, ?-adrenergic responses to catecholamines are most normally associated with the activation of ?1-adrenergic receptors. Nevertheless, cardiac musculus besides possesses a important population of ?2-adrenergic receptors ( Brodde. , 1991 ; Kaumann et al. , 1987 ) and a infinitesimal population of a1-adrenoceptors ( Lutz et al. , 2003 ) . In this survey, we used a selective concentration of Tenormin, which has antecedently shown to hinder the positive ionotrophic consequence of catecholamines. The selective concentration of the Tenormin ( 10 µM ) was chosen to be 1  ± 2 orders of magnitude above its several pA2 ( Borje J. , 1979 ; Kenakin. , 1993 ) . No consequence of selective Tenormin on cardiac recovery was seen, which could be due to two grounds: a ) there was no endogenous release of catecholamine B ) an increased contractility was a consequence of catecholamine moving on receptors other than ?1-adrenoceptors ( ?2 and a1 receptors ) , which are non antagonised by selective concentration of Tenormin. If latter was the instance, should we have observed a recovery in contractile map with higher concentration of Tenormin? Well, no discernible recovery in cardiac map was seen with higher doses of Tenormin ( 50 µM ) . For case, if atenolol ( 50 µM ) was moving on ?2-adrenoreceptors so it would hold caused a diminution in bosom rate, which was non the instance in this survey. It could besides intend that 5-fold higher concentration of Tenormin ( 50 µM ) . used in this survey, was non powerful plenty to move on receptors other than ?1-adrenoceptors ( ?2 or a1 receptors ) . On the footing of our consequences, we conclude that Tenormin did non hold a cardioprotective consequence, which could be due to really low concentration of catecholamines present in the nervus terminations. However, the dependability of our decision is so problematic as there was a batch of variableness in the consequences which made it complicated to construe. Study restrictions Perfusion force per unit area was provided by adding appropriate sum of trial solution to the reservoir. In some instances, reservoir was non topped up and this would hold led to low hydrostatic force per unit area, therefore a low coronary flow the latter is thought to be straight relative to perfusion force per unit area ( Fiona et al. , 2003 ) . It is hence of import to utilize a changeless perfusion force per unit area of 60-100 mmHg utilizing a perfusion force per unit area transducer, connected to a tripartite pat instantly above the aortal cannula ( Fiona et al. , 1999 ) . In this survey we merely controlled temperature of perfusion solution utilizing a heat money changer. Surveies have shown that alterations in tissue temperature are associated with LVDP and bosom rate steps ( Fiona et al. , 2003 ) . A alteration could be made by environing the bosom with a thermostatically controlled water-jacked chamber to keep its temperature at 37.0 ±0.2 °C throughout the experiment. In add-on, Black Marias could besides be maintained at 37 °C during ischaemic period. For better reading of consequences, one could utilize another ?-adrenoceptor adversary, such as propranolol, which acts on both ?1 and ?2-adrenoceptors. This would bespeak drug action on ?2-adrenoceptors, therefore giving us a clearer image of the presence of catecholamines, if any. On the other manus, catecholamine could be added exogenously, in the presence or absence of Tenormin, to detect any differential effects. Other possible betterments include widening the reperfusion clip from 10-min to 1hr, in order to detect farther alterations in cardiac map. Furthermore, the whole experiment could be done in one twenty-four hours clip to minimise influences of environmental conditions. Mentions: 1.
