Metabolism

Now that you are familiar with the structure of prokaryotic cells, we can discuss the activities that allow these microbes to thrive. The life support activity of even the most structurally simple organism involves a large number of complex biochemical reactions. Most, although not all, of the biochemical processes of bacteria also occur in eukaryotic microbes and in the cells of multicellular organisms, including humans. However, the reactions that are unique to bacteria are fascinating because they allow microorganisms to do things we cannot do (Neidhardt & Holde, 1990). For example, some bacteria (the chemoautotrophs) can grow on diets of such inorganic substances as carbon dioxide, iron, sulfur, hydrogen gas, and ammonia.This paper examines some representative chemical reactions that either produce energy (the catabolic reactions) or use energy (the anabolic reactions) in microorganisms. We will also look at how these various reactions are integrated within the cell.II. Discussio nA. Catabolic and Anabolic ReactionsWe use the term metabolism to refer to the sum of all chemical reactions within a living organism. Because chemical reactions either release or require energy, metabolism can be viewed as an energy-balancing act. Accordingly, metabolism can be divided into two classes of chemical reactions—those that release energy and those that require energy. In living cells, the chemical reactions that release energy are generally the ones involved in catabolism, the breakdown of complex organic compounds into simpler ones. These reactions are called catabolic, or degradative, reactions.On the other hand, the energy-requiring reactions are mostly involved in anabolism, the building of complex organic molecules from simpler ones. These reactions are called anabolic or biosynthetic reactions (Neidhardt & Holde, 1990). Anabolic processes often involve dehydration synthesis reactions (reactions that release water) and require energy to form a new chemical b onds.Examples of anabolic processes are the formation of proteins from amino acids, nucleic acids from nucleotides, and polysaccharides from simple sugars. These biosynthetic reactions generate the materials for cell growth. Catabolic reactions are generally hydrolytic reactions (reactions that use water to break chemical bonds). Chemical bonds store energy; when they are broken, chemical energy is released. An example of catabolism occurs when cells break down sugars into carbon dioxide and water.Catabolic reactions furnish the energy needed to drive anabolic reactions. This coupling of energy-requiring and energy-releasing reactions is made possible through the molecule adenosime triphospahte (ATP). ATP stores energy derived from catabolic reactions and releases it later to drive anabolic reactions and perform other cellular work. A molecule of ATP consists of an adenine, a ribose, and three phosphate groups.When the terminal phosphate group is split from ATP, adenosine diphosphat e (ADP) is formed, and energy is released to drive anabolic reactions. Using P to represent a phosphate group, we can write this reaction as (ATP—> ADP + P + energy). Then, the energy from catabolic reactions is used to combine ADP and a P to resynthesize ATP (ADP + P + energy—> ATP).Thus, anabolic reactions are coupled to ATP breakdown, and catabolic reactions are coupled to ATP synthesis. This concept of coupled reactions is very important. For now, you should know that the chemical composition of a living cell is constantly changing; some molecules are being broken down while others are being synthesized. This balanced flow of chemicals and energy maintains the life of a cell (â€Å"Metabolism; What is it exactly and how fast or slow should it be?†).B. EnzymesChemical reactions occur when chemical bonds are formed or broken. In order for reactions to take place, atoms, ions, or molecules must collide. Whether a collision produces a reaction depends on the spe ed of the particles, the amount of energy required to trigger the reaction (called activation energy), and the specific configuration of the particles. The physiological temperature and pressure of organisms are too low for chemical reactions to occur quickly enough to maintain the life of the organism.Raising the temperature and pressure and the number of reacting molecules can increase the frequency of collisions and the rate of chemical reactions. However, such changes could damage or kill the organism. The living cell’s solution to this problem is a class of proteins called enzymes. Enzymes can speed up chemical reactions in several ways. For example, an enzyme may bring two reactant molecules close together and may properly orient them to react. Whatever the method, the result is that the enzyme lowers the activation energy for the reaction without increasing the temperature or pressure inside the cell (â€Å"Immobilized Enzymes Can Check Bioterrorism, 2003).Substances that can speed up a chemical reaction without themselves being altered are called catalysts. In living cells, enzymes serve as biological catalysts. As catalysts, enzymes are specific. Each acts on specific substance, called the enzyme’s substrate (or substrates when there are two or more reactants), and each catalyzes only one reaction. For example, sucrose (table sugar) is the substrate of the enzyme sucrase, which catalyzes the hydrolysis of sucrose to glucose and fructose.The specificity of enzymes is made possible by their structures. Enzymes are generally globular proteins that range in molecular weight from about 10,000 to several million. Each of the thousands of known enzymes has a characteristics three-dimensional shape with a specific surface configuration as a result of its primary, secondary, and tertiary structures. The unique configuration of each enzyme enables it to â€Å"find† the correct substrate from among the large number of diverse molecules in t he cell (â€Å"Immobilized Enzymes Can Check Bioterrorism, 2003).C. Factors Influencing Enzymatic ActivitySeveral factors influence the activity of enzyme. Among the more important are temperature, pH, substrate concentration, and inhibitors.a.) TemperatureThe rate of most chemical reactions increases as the temperature increases. Molecules move more slowly at low than at higher temperatures and may not have enough energy to cause a chemical reaction. For enzymatic reactions, however, elevation beyond a certain temperature drastically reduces the rate of reaction. This decrease is due to the enzyme’s denaturation, the loss of its characteristics three-dimensional structure (tertiary configuration). Denaturation of a protein involves breakage of hydrogen bonds and other noncovalent bonds (Neidhardt & Holde, 1990).Most enzymes have a pH optimum at which their activity is characteristically maximal. Above or below this pH value, enzyme activity, and therefore the reaction rate, declines. When the H+ concentration (pH) in the medium is changed, many of the enzyme’s amino acids are affected and the protein’s three-dimensional structure is altered. Extreme changes in pH can cause denaturation (Neidhardt & Holde, 1990).Substrate ConcentrationThere is a maximum rate at which a certain amount of enzymes can catalyze a specific reaction. Only when the concentration of substrate(s) is extremely high can this maximum rate be attained. Under conditions of high substrate concentration, the enzyme is said to be saturated; that is, its active site is always occupied by substrate or product molecules. In this condition, a further increase in substrate concentration will not affect the reaction rate because all active sites are already in used. If a substrate’s concentration exceeds a cell’s saturation level for a particular enzyme, the rate of reaction can be increased only if the cell produces additional enzyme molecules (Neidhardt & Holde, 1990). However, under normal cellular conditions, enzymes are not saturated with substrate (s). At any given time, many of the enzyme molecules are inactive for lack of substrate; thus, the rate of reaction is likely to be influenced by the substrate concentration.InhibitorsAn effective way to control the growth of bacteria is to control their enzymes. Certain poisons, such as cyanide, arsenic, and mercury, combine with enzymes and prevent them from functioning. As a result, the cells stop functioning and die.Enzyme inhibitors are classified according to their mechanism of action as competitive inhibitors and noncompetitive inhibitors. Competitive inhibitors fill the active site of an enzyme and compete with the normal substrate for the active site. The competitive inhibitor is able to do this because its shape and chemical structure are similar to those of the normal substrate.Noncompetitive inhibitors do not compete with the substrate for the enzyme’s active site; instead they interact with another part of the enzyme. In this process, called allosteric (â€Å"other space†) inhibition, an enzyme’s activity is reduced because of a change in shape caused by binding of an inhibitor at a site rather than substrate’s binding site. The change in shape can be either reversible or irreversible (Neidhardt & Holde, 1990).III. ConclusionIn conclusion, the sum of all chemical within a living organism is known as metabolism. Catabolism refers to chemical reactions that result in the breakdown of more complex organic molecules into simpler substances. Catabolic reactions usually release energy. Anabolism refers to chemical reactions in which simpler substances are combined to form more complex molecules. Anabolic reactions usually require energy. The energy of catabolic reaction is used to drive anabolic reactions. The energy for chemical reactions is stores in ATP. Moreover, the enzymes are proteins produced by living cells that catalyze chemi cal reactions. They are generally globular proteins with characteristic three-dimensional shapes.Reference:Neidhardt, F.C. and K.E. van Holde. Biochemistry. Redwood City, Calif: Benjamin/Cummings, 1990.

Spirometry Report Essay

Use your PowerPoint notes, lab book, text book, your data, and the Internet to answer the following questions. All reports must be typed and stapled. All reports must be in your own words. One student from each group should include the LabTutor-generated data tables and/or graphs. Exercise 1: Pulmonary function tests Respiratory parameterUnitsExperimental ValuePredicted Value* BPM14 TVL0.490L IRVL1.984L ERVL0.905L RVL1.45L   1. What is the residual volume and why is it important to normal respiratory function? – Residual volume is the volume of gas remaining in the lungs at the end of forced expiration – It is important to normal respiratory function because it helps to keep the alveoli patent (open) and prevent lung collapse. It decreases the efficiency of gas exchange by diluting the oxygen of the inspired air. 2. Briefly describe Spirometry. – Spirometry is the most common of the pulmonary function tests, measuring lung function, specifically the volume and the flow of air that can be inhaled and exhaled. – Spirometry is the most useful for evaluating losses in respiration function and for following the course of certain respiratory disease. 3. Explain why the residual volume cannot be determined by Spirometry. -Because pirometry can only measure how much air is moving out of or into the lungs, not how much is contained at a particular time. 4. You are a Nurse working a 19:00 to 07:00 shift. There are no attending physicians on your service and all the residents are sleeping. One of your patients is demonstrating signs of dyspnea. You call the respiratory service and an RT responds and conducts a PFT (Spirometry)  series on your patient. There is a â€Å"malfunction† with the equipment and the RT tells you that you can only have â€Å"one value†!! Which value do you choose and why? (3 pt). -I choose value the TV â€Å"Tidal volume†, because I would like to know the amount of air inhaled and exhaled with breath under resting conditions of the patients. Exercises 2 & 3: Pulmonary Function Tests: Compare the respiratory parameters between normal and simulated obstruction. Recall, we simulated an obstructive pulmonary disorder by covering the tube with duct tape and cutting an opening in it about the size of a pen’s diameter. Using the Horizontal Compression controls and the scroll bar, display the data for both normal pulmonary function tests (Exercise 2) and the simulated restricted airway (Exercise 3) for inclusion in your report. Normal: Respiratory parameterExperimentalPredicted FVC3.392L PIF214.55L/min PEF237.09L/min FEV12.438L FEV1/FVC71.88% Simulated Airway Restiction: Respiratory parameterExperimentalPredicted FVC2.101L PIF24.04L/min PEF26.24L/min FEV10.188L FEV1/FVC8.95% Study Questions 5.There are two major categories that lung diseases fall into: Obstructive and Restrictive. Construct a small table for each lung condition (obstructive or restrictive) and predict what spirometry parameters that we measured in lab would most likely be decreased, which parameters would most  likely be unchanged, and which parameters (if any) might be increased. (3 pt). ObstructiveRestrictive FVCnormal or minimally decreased decrease PIF PEF FEV1decreasenormal or minimally decreased FEV1/FVCdecreaseNormal or increase TLCNormal or increasedecrease 6. Explain the pathologies of Obstructive and Restrictive pulmonary diseases. Include in your discussion why these pathologies result in the signs and symptoms of each disease class. Also name at least two conditions associated with each major pulmonary disease class (i.e. Chronic Bronchitis-Obstructive) (3 pt). – Obstructive pulmonary diseases have shortness of breath due to difficulty exhaling all the air from the lungs. Because of damage to the lungs or narrowing of the airways inside the lungs, exhaled air comes out more slowly than normal. At the end of a full exhalation, an abnormally high amount of air may still linger in the lungs. * Two conditions associated with obstructive pulmonary diseases are: a) Asthma b) COPD which include the emphysema and chronic bronchitis. – Restrictive pulmonary diseases cannot fully fill their lungs with air. The lungs are restricted from fully expanding. * Two conditions associated with restrictive pulmonary diseases are: a) Pneumonia: b) Scoliosis 7. Describe the physiology of the FEV1/FVC ratio and what is the clinical significance of an abnormal ratio? DO NOT provide the definition of the ratio (3 pt). – The significance is that it describes the effectiveness of how well an individuals lungs can turn over its total volume in 1 second. – The clinical significance of an abnormal ratio is 8. What values have been affected by simulated airway restriction? FVC 9. Are these values the ones you would expect to be altered in â€Å"real† restrictive pulmonary disease? Why or why not? (2 pt). Yes. Because we would expect to know the value of the airflow is constantly decreasing, if it was restrictive the volumes and capacities would have been affected more than what it was. 10. Based on how the subject felt during this lab exercise, what â€Å"coaching† would you give to a patient having an asthma attack in an attempt to get them to move more air. Refer to your Physiology of Breathing lecture notes. This is one of the few times I want to see a direct reference (3 pt). – Using the quick relief inhaler (like the albuterol) as prescribed using a spacer, if it is available. * Shake inhaler, exhale, release one puff, inhale, hold breath for 10 seconds, exhale and wait 1 minute. Repeat till at directed dose. * Inhale slowly and deeply when using a spacer. – If the patients have no inhaler, keep the patients calm and encourage breath slowly. Let the patients sit up and breath in slowly through the nose and out through purse slip.

High School Life

Robert Revilla Mr. Osman English 35 #31127 March 17, 2013 The Past and Present of Teenagers Ask any teenager today and they will tell you that they are nothing like their parents, that their parents just don’t understand them. This may be true and this may be false, it just depends on how you look at it. Teenagers of the Rebel Without a Cause, meaning the parents of today’s teens, did face a lot of the same problems and issues that we now face. Yet I am left thinking did the past teens face all the same problems at the same time as we do and were some of their â€Å"problems† not as much of a problem as it is to us.Teens from the past and present are faced with problems such as school, relationships, and friends. There were many teenage problems back then in â€Å"Rebel Without a Cause† and today’s teenagers. Most of these problems that Jim Stark and the other teens faced were similar, but my own belief is that these same problems were not as big of problem back when they were growing up. Let’s take school and homework for example, oh sure your parents had it too but I just don’t believe that there was as much pressure upon them to get good grades. Also, get into a good college as there is for us.And of course with the knowledge that college is right around the corner most teens also need to work. They need to save money for college, or a car, or to make the girl/boy of their dreams happy by taking them out on dates once in a while. Plus, all this pressure and work can build up for a teen and to most of us it seems like we never have a chance to just relax and hang out with friends anymore. It relates to the movie because some of the teens do not care about homework or going to school. The reason is that was back then it was easy to get a job by only having a high school diploma with no college education.But, now in our teen lives it is hard to get a job with a high school diploma. Another thing that is different from the past from the present is the fashion that students wear. In the past, boys wear plain regular clothes and the cool guys always wear black jackets or blazers. It is similar like what a gang member usually wears right now. Except the gangs have their baggy pants or shorts and show their boxers in black or white. It is weird how those kind of guys like to show-off their boxers or underwear. For the girls in the past, they all mostly put on dresses. Now girls mostly wear skirts or short shorts.Plus, girls always try to put on the sexiest clothes to wear because to get all the attention and be popular. Like in the movie, Jim Stark wears different clothes from his classmates. The reason is that he moved to a lot of different high schools because he never made any friends and doesn’t fit in with the other teens. Also, in every high school he went to the teens called Jim, â€Å"Chicken†. Why he is called that because the teenagers see him acting like a chicken, when Jim does not want to get into trouble. I think back then music for teens like, â€Å"Rebel Without a Cause†, probably listened to rock and roll.But now teens prefer rapping and hip hop music. It’s interesting how music has changed so much in the past because teens loved to get crazy on rock and roll. I wonder how teens will react if music never came to rock and roll. Probably teens will make their own music or have to try out their parent’s music, which were more hip hop and dance music. Now teens today have a mix of genres they like to listen. Most teens in the present relate their music to their emotions. The reason is because they must have some problems in their lives and music helps teens release stress.Plus, I am sure that it happens to the teens in the past except not big problems compare to our teen years. I bet Jim Stark and his classmates love to listen to rock and roll. Even though it does not show in the movie that they played rock and roll, but back then there was a lot of rock and roll. The teens in the early years prefer rock and roll because it was something they can be themselves with their friends. Sometimes parents cannot stand their teen’s music and tells them to turn it off or take it away from them. It is weird how in the movie, it shows parents like Jim’s parents how they do not care about his school issues.For instance, when Jim’s classmates call him chicken, he tells them to stop and be angry to his parents. Then Jim’s parents decide to move somewhere else again, which happen several times. Jim does not want that because he thinks it is going to happen all over again. So, basically Jim’s parents do not really help him and his life that much. But comparing to today’s teens, Jim’s parents and other parents show more concern for each of their son/daughter’s education to make them successful in life. I can see that every year new parents learn from their past seei ng their mom and dad on how they take care of their son or daughter.Then later on the new parents learn from their parent’s mistakes and become a better parent. There are things that are similar between our time and the movie, â€Å"Rebel Without a Cause†. One is that teens hate doing homework and waking up early for school. Teens in the past and present struggle with their emotions like in relationships or family issues. Jim shows his emotions to his parents in the movie. He tells them how he feels every time when he transfers to a new school and he is not good at making any relationships or friends.The main reason is everyone calls him chicken because he is different from his classmates and they think he is afraid of them. I just want to say that I am not saying that teenagers of the past did not have their own problems, but of course they did, every single teen alive faces problems that they think is hard and that their whole world is crumbling down around them well at least once in a while. But now that they have grown up and turned into the parents of today’s teenagers I feel that they put more pressure upon their own teenage child in order for them to achieve more than they were able to.A common expression is, â€Å"My parents are so strict, overprotective, or too involved in my life, because they don’t want me making the same mistakes they did when they were my age but they need to trust me and just leave me alone. † And that expression can sometimes is kind of true. But all in all I feel that our parents do understand what we, as teenagers, are going through because they did face the same problems that we face today, but maybe with just a little less pressure.

Definitions of Green Engineering Essay Example | Topics and Well Written Essays - 2250 words

Definitions of Green Engineering - Essay Example Green engineering is basically an attempt to find a why between complex engineering processes and the need of securing the environment. It can also be used a pedagogical tool by incorporating broader environmental issues into scientific analyses (Shonnard, Allen, Nguyen, Austin, and Hesketh 5453). Considering the importance of green engineering for environmental sustainability, most of the educational institutes have also started to incorporate a combination of green engineering principles and scientific training into engineering education. The aim is to make students and future engineers able to save the environment by adopting the concept of green engineering based on effective mathematic techniques and unique scientific principles. This paper describes three main conceptual frameworks of green engineering in detail to know the similarities and differences between them. The aim is to come up with a proper definition of green engineering based on which engineers can base their engin eering designs and plans. The thesis statement for the paper is, ‘Whatever conceptual framework is adopted for green engineering design, the underlying aim in all of them is to cater to the needs of the sustainable environment and those of the community’. ... To me, McDonough and Braungart, in Cradle to Cradle, seem to be emphasizing on the production of such products that are less harmful for the environment upon becoming useless for people. They speak for the concept of ‘upcycling’ and suggest designers to keep in mind the ecological compatibility, as well as the environmental consequences of products. However, designers need to put a great effort to meet all demands of the Cradle to Cradle framework. The reason is that, at present, there is not much emphasis on redesigning or restructuring the design and development processes and in order to go with the Cradle to Cradle framework, designers need to transform all processes of product design and development completely to make them compatible with the needs of sustainable environment. I would say that the aim of McDonough and Braungart in Cradle to Cradle is obviously to create and maintain the natural environment by minimizing the effects of industrial products when they bec ome useless. They have focused on the need to change the current system because it can produce disastrous effects for the ecosystem. Obviously, the aim of zero waste cannot be achieved under current system not only because of changing human needs and demands regarding products but also because of industrial processes of product development that produce waste some way or other. However, manufacturing of products in such a way that they can be recycled upon reaching maximum life can be a substitute for the aim of achieving zero waste (McDonough and Braungart 42). Therefore, engineers should adopt such methods of manufacturing that should make the products recyclable and eco-friendly. Anastas and Zimmerman, on the

Case Study Write up (Don't have any topic) Example | Topics and Well Written Essays - 500 words

Write up (Don't have any topic) - Case Study Example The business owners need to create a variety of fresh content for their social media every week. Furthermore, owners should use a variety of social media platforms such as: Twitter, Facebook and Instagram. Previously, owners mainly used word of mouth to promote their products. Using social media platforms has its disadvantages including: the owner needs to change content regularly so as to keep the consumers interested, and they also have to focus on a single media platform since using several shall confuse the consumers. The advantage of using social media platforms is that the business owner can increase participation in offline activities. The information in the social media platform can be updated from time to time. If the business is in a van, the consumers can easily know your new location and this ensures that you maintain a loyal customer base. Using television ads: Televisions are a common feature in almost every modern household. This means that business owners can reach a wide range of consumers with this form of marketing. This form of marketing is extremely expensive and time consuming since the commercial has to be acted out by professional performers. Word-of-mouth: This form of advertising involves telling people about your business by speaking to people. This is an extremely cheap means of marketing since all that is needed are some sweet words and charisma. However, this form of marketing is quite tedious since one must walk around stopping complete strangers and convince them to come buy their product. Using placards: This form of advertising is good for a small business since it provides a detailed summary about the business. The only disadvantage is on illiterate people who will not be able to decipher the information. Using radio ads: Radios are the most widespread electronic communication device in rural areas. This form of marketing means that the small business owner can reach

Role of Farmers Markets in the Mainstream Food System Research Paper

Role of Farmers Markets in the Mainstream Food System - Research Paper Example Farmers markets in Ontario nowadays have become one of the hottest shopping spots where consumers drop in to buy fresh vegetables and fruits directly from the farmers. It has been revealed that â€Å"In Ontario.... sales at Farmers Markets total almost $600 million, leading to an economic impact of an astounding $1.8 billion† (Farmersmarketsontario). Some other studies have shown that â€Å" 60 to 70 percent of market-goers visit neighboring businesses on their way to and from the market† thereby helping other local businesses also to flourish (Farmersmarketsontario). Some farmers markets have also been contributing their profits to social causes in the form of donations to the local senior centers, libraries, and schools, thereby linking the local economy with social upliftment (Hinsley and Pascoe, 1). In addition, a review of the materials available regarding the farmers market has indicated that the 100-mile diet concept is promptly fulfilled by this initiative. This concept has a meaning that, you â€Å"try eating only from producers within 100 miles of your home† (Winter, 88). This decision is taken in order to contribute to the sustainability of local agriculture and local livelihood as well as to evolve a healthy eating habit in which maximum fresh food is consumed. The farmer's markets have also been lauded as environmentally friendly because, â€Å"locally produced food has not traveled hundreds of miles to reach them (the consumers), increasing the fossil fuel emissions that lead to global climate change† (Hinsley and Pascoe, 2).  Ã‚  

In what cases is U.S. military intervention in other countries Research Paper

In what cases is U.S. military intervention in other countries justifiable In what cases is it not - Research Paper Example In any case, America is fighting with other countries all the time one way or other. It is difficult to justify all these wars conducted by United States. The Afghanistan war can be justified up to certain extent because of the brutalities committed by the Muslim fundamentalist group Taliban. Moreover, America has support from the existing Afghanistan political regime in destroying Talibanism from Afghan soil. However, same thing cannot be said about the recent Iraq war. It was conducted against the will of the political administration in Iraq. Moreover, the reasons cited for attacking Iraq were rejected by other countries. The theory of weapons of mass destruction was indigestible to other countries. America is still struggling to justify Iraq war since they failed to seize any weapons of mass destruction from Iraq. This paper analyses in what cases is U.S. military intervention in other countries is justifiable and in what cases is it not. On March 20, 2003 America with the help of its allies attacked Iraq, accusing Iraq for the possession of illegal chemical, biological and nuclear weapons or weapons of mass destruction. Moreover, America explained to the world that the possession of such serious weapons may cause immense threat to the global peace. However, even after the execution of Saddam Hussein, American troops failed to seize any such weapons from Iraqi soil. ... It is illegal to attack a country for exploiting its natural resources. Sovereignty of a country should be respected in order to keep global peace intact. It is fact that most of the Middle Eastern countries including Iraq were administered by some dictators. However, spreading of democracy through war cannot be justified under any circumstances. Bush Jr. spent billions of dollars just for saving the pride of his father. The current financial crisis is believed to be the by-product of Iraq war. In other words, Iraq war not only affected the Iraqi people, but it affected the Americans also. Many of the American soldiers sacrificed their lives in Iraq in their efforts to bring peace back in Iraq. The cost of Iraq war can be better analyzed with the help of following illustration. (Cost of Iraq War and Nation Building) â€Å"According to an article by Stephen Gowans, the US command knowingly violated Article 54 of the Geneva Convention which prohibits any country from undermining objec ts indispensable to the survival of (another country's) civilian population" (Abuelo). Iraq war resulted in large scale looting and criminal disorder, especially in Baghdad and Basra. Coalition forces were quite unable to maintain public order and the Iraqi police forces largely withdrew from the major centers of population (Rogers, p.13). In other words, the coalition forces failed to keep their word they given to the external world; a peaceful Iraq without Saddam. In short, Iraq war or America’s intervention in Iraq could not be justified under any circumstances. The reasons cited for the wars were illogical and Americans forced pay big prices for this war in the form of big expenditure and the sacrifice of the lives of many of its people.

Job Security between India and Japan Essay Example | Topics and Well Written Essays - 2000 words

Job Security between India and Japan - Essay Example Moreover, the current report will also execute the theoretical and practical implications of the IR transformation outlook. The laws of employment dominating India, the newly industrialized country are of a safeguarding nature to the employees. They permit the policies of workers’ retrenchment or lay-offs but only with government’s approval. On the other hand, the condition of labor in Japan, the advance-industrialized country, gives a differing outlook. The practices of labor, there, depict distinguishing aspects, of which, the most prominent is the ‘lifetime employment’. This assists the workers in the provision of beneficial behavior by hiring those schools, maintaining retaining, and developing them in the companies or organizations until they are 55-60 years. This provision of lifetime guarantee does not require the workers to sign any particular contract and is flexible towards the employees throughout their job. Various researches and studies regarding the employment security in India depict that the rate of unemployment in India is higher than that of Japan. The Indian Government is responsible to formulate the laws of industrial relations. Some of such IR laws prevailing in India are worth mentioning in the context of the report. Moreover, the IR laws in India are distinguished by the Industrial Relations laws of other countries through the feature that it does not provide for trade unions to be acknowledged as the collective bargaining agents. Under the TUA, only registering of the union does not give it the status of a legal and autonomous representative of the employees in the organization (Sarkar 2011). The Industrial Law makes it mandatory for the government to interfere in tackling any disputes that emerge in the organizations and its activities. According to the provisions of the Industrial Disputes

Why is the Kashmir dispute the oldest unresolved international Essay

Why is the Kashmir dispute the oldest unresolved international conflict in the world today - Essay Example factors including, social, cultural, religious and political have played a vital role in the process to exist Kashmir dispute as an unresolved problem. In the shadow of political crisis, there are some antisocial activities such as terrorism, fanaticism and jihad (holy war) in Kashmir region. Cases related with the violation of human rights have an integral role in the discussion, why Kashmir dispute became the oldest and unresolved international issue in the world? The people in Kashmir demands self governance and many people believe that both India and Pakistan should a positive decision in this self governance which may be a significant step in reducing the conflict. Anyhow, the conflict between the world’s newest atomic powers resulted severe security problems in Indian subcontinent. Kashmir dispute has a rich historical background and it is not only a political issue between India and Pakistan but a last long crisis having various phases. Before the time of Indian independence, the state of Jammu Kashmir was a ruled by Hari Singh, a Hindu ruler and who tried to maintain his states as independent. Because of the presence of majority Muslim people some Pakistani leaders have argued that Kashmir region belonged to Pakistan. In 1947 Pakistan sent some tribal infiltrator to catch Kashmir and the Maharaja pleaded military aid for Indian army. Maharaja had ignored the opposition of the native people and he signed the agreement of the Instrument of Accession with Indian Government. Historical studies exposes that it is this event that resulted for the so called turmoil of the people who settled in Jammu and Kashmir. While turning over the pages of history, it is quite observable that for many years the people of this region were seeking for their cultural identity. The boundary problem between India and Pakistan paved the way for the unending crisis and it had affected not only the formation of the foreign policies of India and Pakistan but also various factor

Lifestyle Choices Essay Example for Free

Lifestyle Choices Essay The article â€Å"Lifestyle Choices† is a researched article that talks about the economy and how changes affect the people within it. The Starter research article contains informative information on daily lives about health care, in today’s modern society we go through various choices in life and different walks in situations weather it financial situations, family issues or even work related problems. This article shows how to outweigh the bad to good and exercise good habits to create a better lifestyle. This research goes back and covers the last thirty years dating back when technology was the grounds of being formed. Something’s I enjoy about life is the fact that grounds for technology were being formed when I as a baby had no knowledge or use of it, such as the children(s) today. Social class determines your lifestyle form of living; it’s the group you belong to based upon your financial situations. This is one research that cannot be control or determined you can be an upper class person or a lower class person and sometime due to the luck of a draw it can flip anytime. That’s what I like about the topic â€Å"Assessing Class† because their no way unless you have no improvements to access another class. What I learned from this article is that hasn’t shy away from any topics considering our lifestyle issues and situations. It clearly states the factors of social classes a great overview of information. This article very much fits into sociology as it apart of our daily lives which includes the study of human society and its origins, development, organizations, and institutions. The major findings come from the data or series of surveys that has been done over decades of study’s which mostly includes volunteers to complete most studies. Lifestyle studies can be best examined through ethnicity our race, age, and suburban areas of residency and sexual preferences. This information was supported and document by Michael Sobel (1983) which he states, acknowledges, and compares sociology to our daily lifestyle as a â€Å"Mode of living.† He also presents the concept of stylistic unity by which he means the patterns of behavior which constitute that lifestyle are empirically common; i.e., similar patterns are shared by a sufficient number of others, relative to all others. This article fits well with chapter 1 (Seeing Sociology in Everyday Life) under â€Å"Marginality and Crisis. I believe it fits here because it’s bringing the recipe for looking at the world’s society from a sociological perspective. What is used to reshape the economy and separate them though classes. The difference between this article that sets it apart from non-scholarly periodicals, such as newspaper and magazine is the fact that non-scholarly periodicals are mainly used to entertain. This journal has an abstract, a descriptive summary, and properly cited. Non-Scholarly are not completely from a known source it can be made up and the timing of the report can be inaccurate at times. They serve a different audience. What I find similar of the two is they can be found in the same place or setting it is up to the reader to select the one needed as far as common within there is none they are two completely different types of sources and everything must be documented or researched differently. From the introduction, word fonts to work cited they are done accordingly to source or audience.

Reflective presentation of the risk assessment conducted in ealing christian centre

Reflective presentation of the risk assessment conducted in ealing christian centre Introduction Under the permission of the head pastor of Ealing Christian Centre, Northfield, London, I was granted the permission to do my practical placement with the church in December 2008. I was directed to the staff in charge of the churchs health and safety whose induction given to me in December 2008 and willingness to supervise me in my forty hour practical project scheduled to start on 11th January 2009 was beneficial to me. Since the church building and it surrounding environment are places where people often meet to fellowship, it is very important to ensure the safety of these places such as the Church, the Church halls, churchyards and ground are safe for worshipers and staff to use. If these places are ignored of assessing their risk of usage they can cause serious pain and suffering to people which may often disrupt the peaceful running of the church and its activities. Risk assessment by definition is suggested to be a progressive stage in risk management process, which determine s measurable characteristic value of hazards in relation to definite situation and the identification of the threat. And in this practical reflective presentation, I will base the health and safety risk assessment I conducted in Ealing Christian Centre on the Systems put in place for safer place of worship as briefed by my supervisor at induction, and the Daily Time log on my observations. Systems Put In Place for Safer Place of Worship Security of the Church Building Ealing Christian Centre as I learned from my induction day, is a big building used as place of worship for both able and disabled adults, young people and children of various age groups. The boundaries of the church premises are clearly defined with concert walls and good wooden fencing. The door ways are protected such that they do not give cover to intruders. When not in use, all the entrances and windows are securely locked. There is no easy access from points such as lower adjacent structures, compounds, walls or pipes to the roof and has an intruder alarm installed there. I also learned that their musical instruments, computers and private files are securely protected from thieves. Vehicle access to the church grounds as I learned was controlled only on Sundays and any other major event in the church. There is a gate that is locked to prevent access when the parking spaces are full. Theft and Damage There are storerooms for securing valuable items such as audio, visual and musical instruments when they are not in use. The church has offices which are also locked when not in use but all staff and members are advised to safeguard their personal belongings in the church. Cash is counted in a secure room out of sight, removed from the premises overnight and holdings are kept in the minimum, stored in safe installed for small valuable items. The offering how ever is not adequately protected from theft since the offering basket allows every hand to reach the collected money at its base. Items that could be used as missiles to commit damage are removed from around the building, and refuse stored safely away in metal containers from vulnerable areas. Management and Practice The church has no specific annual budget for crime and vandalism prevention measures separate from any general repair funds. Even though staffs have suggested people should report acts of vandalism immediately on recovery, most people do not. However damages are quickly repaired to discourage further similar acts while criminal acts reported automatically to the police if known. Details of the nature, time, place and cost of theft or vandalism are to be recorded in logbooks but mostly it is not done. Advice has been sort from the Police Crime Prevention Office, Fire Prevention Office, the Insurer and the Security Industry so; there is detailed procedure for recording and investigating fires. The community through the police and Church watch scheme are involved in the in safeguarding the church building. But for security reasons there is no procedure put in place for the police and fire service to contact the church key holders in the occurrence of incidents in the building. Other Established Methods There is a proper procedure for keys control and an established procedure for locking up the church. When the building is being locked after activities, the stewards are to inspect the kitchen, toilet, and store rooms to make sure no one is hiding in the building. I learned that the locks of the church are periodically checked to avoid duplication of the keys. Visitors who come to the building are urged to use a particular door that has been signed, but there is no means to monitor the arrival and departure of visitors during church service times and so visitors sometimes wander into the unauthorized areas such as childrens classrooms and office area. There is no arrangement set in place for surveillance during outside opening times except during special events such as youth programmes. This, I find suggest inadequate patrols and checks from the church officials. However, there is an external security lightening system provided to light up the premises during the evenings. Natural s urveillance from the area around the building provides a beef-up security for the premises. There is a caretaker living on the site, whose house is readily accessible. When contractors are working in the building, extra security fitting safety and fire precautions are taken by Christians known by the church. The parties involved meet on the site to identify hazards and correct methods of necessary to handle them during work on site. Most of the people who work alone in the building are the people working in the Prayer Centre and enough provision has been made for their personal safety in the building. During organised childrens events, a register of the children in the building are kept while child protection policies are enforced. Children in the building especially on Sunday services are protected from members of the public who access the building to look for someone or join worshipers. I further learned that all internal fire doors are fitted with self closing devices and labeled to be kept closed with adequate training to relevant people in locating escape routes. The fire escape routes and exits are sometimes obstructed by staff and so memos are often sent to all staff as reminders to keep them clear of obstructions. The floors surfaces are free from tripping and slipping risks and emergency exit doors are free to open from inside the building without using keys. The emergency lighting systems are installed in correct working order and tested weekly. My Observation from (11/01/2009-19/04/2009) I was welcome and introduced to the stewards group for the mornings safety briefings. I went with the supervisor to check the fire exit by the pulpit. On our way I observed that there were some parked chairs obstructing the exit. She notified one of the leaders to see to the removal of the obstruction. I came to help with the arrangement of the seats for the congregation, where I learned how to arrange the seats in their safety locks. A lady asked the supervisor not to use the chairs safety locks in the areas where the elderly people sit because they were not comfortable with the restriction of the chair to one place. The supervisor then explained to her the importance of the safety lock in time of emergency. She told her that it was a standard requirement by the health and safety rules and the purpose was to prevent the chair becoming hazards in case of evacuating the building on emergency. Commitment and response by some stewards to duty, fire alarm testing time and drill was an is sue. I understood that the expected number of stewards for Sunday service was twenty-one; but an average of nine seems to be dedicated to take fire drill by 09:30. Most of them arrive after worship had begun. The possible problem I observed was that most of them miss team briefing and go on the floor without team discussions and so might not be able to react according to team plan in time of emergency. This made me to learn how important team briefing is. Parental control of children before children were separated for safety keeping during service was also an issue since some parents leave their children aged between three to five years to wander dangerously around the information area of the auditorium near where the reserved chairs are parked. The heights at which these chairs are parked in the information area are of much concern. I found that they are parked over the required number of twelve making them unstable and could easily fall over a child who may playfully stray into th e store or an adult who may go there to pick a chair since there is no door at the entrance. In comparism to other churches I had visited, the reserved chair store house was securely locked. From this I learned that children should not be left on their own before they are separated to safety. After the service the stewards checked all the exits and locked them. I visited the non-English speaking evening service. I discussed with my supervisor how safe it was for those who could not read English to escape in times of emergency? She explained to me that safety signs included pictures illustrating the written instructions which could help people who could not read English writings to follow the instruction in case of emergency. I also observed at a point that two groups (the singing team and the Bible college students) have separate meetings on same day. There was no security at the door to question the purpose of all those who came through the door. The safety of staffs children waiting for their parent was of another concern. In the closed reception I saw some children sitting alone in the dimly lit quiet office. Those who entered into the building rand the door bell from outside the reception door and called their names and they were opened from inside the office without any identity check. This suggests that anybody could follow a genuine person coming into the building through the same door into the reception which could easily be opened from inside when access is gained into the reception. In the main auditorium was also another issue of concern on cables of cleaning equipment running across the auditorium floor without any warning signs. Here also, I saw member of staff children playing in a dimly lit isolated area while their parent was busily cleaning out their sight. The storage of chemicals used for cleaning has been provided with a lock but chemicals is left unlocked to easy access to any one including children who may stray into the cupboard. I discussed the issue with my supervisor form which I learned that there is a problem of supportive agreement and commitment among the stewards and some staff concerning health and safety on the floor, which makes the supervisors work very difficult in area of house-keeping, security of staff, worshipers and children. There were times when fire alarm was scheduled to be tested but was not done for the thought and feeling of the discomfort in interrupting church service. I discussed the emergency lighting system with the supervisor and I was shown how they light automatically from a standby barberry power in the event of power cut. The head steward was not in by the time worship started so the fire alarm was not tested. I had a chat with one of the choristers about how safe she felt when on stage; she said lead wires running across the state during worship time made her feel unsafe. From foyer, I observed that door security was of another concern. Once worshipers enter the building they move around without being monitored. I took some time to observe how some worshipers move around in the foyer. I saw a worshiper squeezing himself through a door to the foyer. My curiosity was aroused to find out the safety of the area to which that door led to. I went through the exit leading to the balcony from th e foyer and went through the door and headed to the staircase. I realised that the area was quite and secluded and emergency doors there. The place could be a safe hiding place for anyone with the thought of doing harm in the building. I found two children on the stairs that were vulnerable and could easily be victimised in this secluded area since the attacker could easily escape through the emergency exit out the building. I also observed a woman with mental health issues entering the church and I prompted the attention of an steward and my supervisor. The supervisor said sometimes they come there regularly and when they sit at the main auditorium they employ a steward to sit with them. After service, I observed the lady with the mental health issues walking among children unsupervised in the foyer with children running around. No steward seemed to be trying to control the children from running around. I asked my supervisor if the stewards had any role to play in controlling child ren from running around. My supervisor took me the door of the stewards briefing room and showed me the notice pasted there that. Part of their responsibility after church was to see to it that children are not running around. But to my surprise some of the stewards did not even know what was on the notice pasted there. The supervisor sent two stewards out to control the children from running around. But, the stewards went into the main auditorium and sublimed amongst the crowd. On the day of water baptism, I went round the foyer to see if there was any way to the balcony. The doors were safely locked. In both male and the female changing room, the baptized were given support safely to dry them self and change clothes. I observed some level of risks with the worshipers being baptised by immersion in water and the baptizers in the auditorium. Only one person baptised 25 people, some of them who might be almost twice the height and weight of the baptizer. This could strain his ribs an d back. Some stewards left leaving the remaining work load of locking up for the committed few. I realised that there was the need for Church workers to be aware of their skill, commitments and knowledge of their work and to work as thought they are working for Christ (John 9:4). Conclusion From this practical attachment, I learned the importance of risk assessments in the church environment. I have also learned that despite all the safety measures the church had put in place for the worshipers and staffs to be safe in the building, personal disagreements among some staff and various voluntary workers of the various church departments to implementation of safety measures play major contributing factors that create hazardous circumstances for both children and adult in the Church. This has made me to understand how the effectiveness of good team work in the church environment can affect the health, safety and the security of people in the church.

The Effectiveness Of Election Campaigns

The Effectiveness Of Election Campaigns If there is one specific topic that has generated the most resounding growing political research in the study of voter behavoiur and election outcome, then it must be Do campaign matter? Decades of voting researches have explored this topic either as a co-relation between the effects of campaign on election outcome in new political perspectives or as a critique to the earliest voting behavoiur studies, whatever the rationale for investigation may be, it has ushered the emergence of a new political phenomenon. This essay would be explored from a typical two sided scholarly perspectives either to argue for or against the significances of election campaign in any political entity. Although this style of discussion would offer in-depth and broader academic resources for clearer understanding but may not be able to sufficiently examine the dimension and dynamics of campaigns in political phenomenon because of the limited time constraint. Also this study intends to draw a clearer picture between the importance and irrelevance of campaigns in cognizance of its relationship with some other socio cultural influences providing the liberty of the readers to take academic position on the argument SUPPORT OF CAMPAIGN Even though the literature of campaigning is unlikely minimal among the academic players, entirety of campaign have been eulogized as a key influence on election outcome and voting behavoiur amongst political actors. This view is supported by Holbrook (1996) as he argues that campaign enjoys continuous recognition from other political actors (voters, candidates and parties) but the scholarly community have shown less interest in campaign effects rather concentrated on the sociological and partisan identification, incumbency and its performances, candidate popularity as the essential factors which influence election outcome creating the emergence of the minimal effects of campaign by the earliest political scientist such as Berelson, Lazarsfeld and McPhee, 1954; Campbell et al., 1960 This position of argument influenced series of subsequent campaign researches which tend to primarily define the minimal effect of campaign as it merely activates voters prevailing partisan sentiments, thereby necessarily ignores a variety of other highly relevant campaign effects. Ironically, It is interesting to know how this minimal effects of campaign could create marginal changes in the voter participation can upturn the election outcome Considering the continuous transformation of the political institution, some political scientists ( Iyengar and Simon 2000) have argued that election outcome in any political environment are always shaped by interplay of many factors in which they may not be individually measured. Thus, they argue that assessing election outcome through the singular premise of campaign is unjustified because campaigns are part of the political processes which are traditionally focused on influencing voting decision by conveying certain impression about candidate or political parties In relation to this position, Ornstein and Mann 2000 in his descriptive analysis of the behavioral attitudes of campaigning defined it as a self centered, continual and persuasive political activity that gives the much needed relevance to the retrospective loyalties of the voter which reactivates them to make voter decision, Quite interestingly, he eulogized campaign as a key political instrument used to make a voter make a psychological purchase in correlation with his reasoning. However, such persuasion is achieved through aggressive media channels by engaging the voters feelings in a preferred direction. Because the political contests are predominantly competitive for elective position, the adversarial nature of campaign has reinforcement effect to maximize the voters loyalties in order to win the election is highly commendable. However, it is likely that campaign effects are heterogeneous across individuals and countries. These are the following reasons why campaign do matters; ENLIGHTENMENT EFFECT Recent researches have confirmed that there is a gradual decline of partisanship which given credibility to the significance of campaigns to influence the voter decision. The strength of retrospective evaluation upon the voter choice has been undermined by this decline which provides the fertile grounds for campaign messages to convert their perceived intention by enlightening their political knowledge. Shaw, 1999 and Salmore etal 1989 claim that political parties have failed in its primary duty to provide powerful information about the candidate during election causing a declining level of party identification in the electorate. In similar view ,Ornstein and Mann 2000 argues that there is a gradual decline in voter identification to the ideals of their political parties This is owing to that fact that the sudden change in party policies and in excesses of election primaries has weakened the allegiance of candidate to their political parties. These declining factors have given premises for campaign to persuade the voters intention for voting decision .However; this growing body of research has provided evidence that campaigns can influence voter preferences. This is evident in the study by Trent and Friedenberg (2000). Although voter behaviour are not only persuaded into new converts for opposing parties during campaigns, campaigning events are designed to reactivate pre-existing partisan loyalties of the voters for voter decision. To support this view, Ansolabehere 2006 further argues on the reinforcing model of the campaign effects on voter behavior as product of interplay of private and public information. This is within the premise that people use their cognitive properties (private information) with the campaign communication (public information to make voting decision showing the campaign reactivates their private supposition. VOTER MOBILIZATION AND PARTICIPATION Recent voting research has proved that campaign messages convert pre- voting intention into voting participation during election periods. Most evidently, Holbrook 1996 argues that findings have proved that there is fluctuation of opinions during campaign events which are due to its high content. This exercise tends to encourage public support which in turn influences voter behaviors. Because campaign exercise consists of several events, activities and processes, voter still respond differently to campaign events based on their individuals demographic and political ideals. The effect of these campaign events is that perceptions and opinions about the candidate and political parties are changed by the aggressive media communication which would propel voter participation. This is because researchers have shown that voting intention have been influenced by campaign communication which have strengthen voter participation in the election. Such participation would adversely enhance election outcome. (Kosmidis and Xezonakis. 2010 Personal canvassing, media communication and debates possess a more engaging interactive power to motivate voter participation in electoral processes. All retrospective alliance to his/her partisan party of the voter must be motivated by campaigning platform in order to encourage massive voting decision. However, the specific political act that can provide the engaging platform is campaigning. Certain political researches have not able to specifically measure the turn out effect of campaign on the voter behaviors but considerable evidence provided that voter participation increased during campaign activities. Evidently, in the field experiment by Gerber and Green 2000 on the effect on personal canvassing in the American 1998 Election In relation to the increased voter mobilization as a campaign effect, Bratton 2008 and Schaffer, 2007 collectively suggests that African election campaigns are mainly moments for politicians to engage in mass mobilization and the manipulation of electoral rules in order to increase voter turnout. Specifically in the case of Nigerias general elections of April 2007, Bratton (2008) claims that vote buying and political intimidation are characteristic dimensions of Nigerian election campaigns and are targeted at rural communities. Furthermore, Fournier etal 2004 argued that time-of-voting decision has been suggested as a key mediating variable for campaign effects. In other words, campaign messages tend to convert voting indecision to positive decision, or from one candidate choice to another thereby making the voter open to campaign persuasion. The media coverage and debates during the campaign influenced the voter intention drawing a co- relation between time of decision and the persuasion of campaign messages. In their researches, they confirmed that late deciders are responsive to campaign events in Canadian elections VOTER LEARNING Every voter needs information to make any type of voting decision either to reinforce his existing partisan loyalties or to make new voting decision. However, campaign is the most appropriate electoral process to provide such function. Because of the vast information- generating nature of Campaign, it provide the avenue for voter learning- the acquisition of information about the candidates and issues .During campaigns the political awareness are enlarged and fundamental voter preferences are being enlightened (Gelman and King, 1993), while the campaign learning process informs voters party positions and issue stances (Peterson, 2009). Campaign occupies the prestigious role as an educational academy for political learning through its information communication about the electoral system which enables the voter to understand the ideologies of the candidate, thereby offering them an enlightened voting decision. To support this stance, Iyengar and Simon 2000 describes campaigns as multifaceted and information-rich events which encompasses the candidates chances of winning, their personal and political ideologies giving campaign events (debates, candidate advertising) the opportunity to expose the voter knowledge to the personality of the candidate by boosting citizens political information, which may increase their likelihood of supporting the particular candidate Evidently, Hillgus and Jackman 2002 in the examination of the campaign effects in the presidential election 2000 in America party argue that conventions and presidential debates affected vote preference. They explored their research using the transition model to individual-level campaign data and concluded the effect of a campaign event based on the voters, campaigning timing, candidate Similarly, the effect of campaign for voter learning were evidently backed by Survey Researches such Brians Wattenberg 1996 and Zhao Chaffee 1996 as they found out that exposure to candidate marketing through the lens of campaign enhance voter learning which would encourage their voting participation Campaign communications increases the voters political understanding, thereby reducing uncertainty around the voting decision. Most recently, Kosmidis and Xezonakis 2009 executed an exploratory research on the undecided voters in the 2005 British general election; their finding confirmed that specific campaign messages formulated the choice preference of undecided voting behaviours. Agenda Control Traditionally, it is believed that voters choose whatever political interest based on their consideration of importance; ironically, campaign communication determines this consideration because of the cycle of appearance in media. Campaign messages surround its themes around those key interests and communicate them strategically in the media to set the agenda for relevance. Dalton etal 1995 suggests that because candidates are the principal sources of news during campaigns, they are in an advantageous position to simultaneously influence the media and public, for instance, candidates are motivated to introduce and pursue issues on which they enjoy a comparative advantage. The candidate closer to the student voter on an issue like fee reform would want to address that topic, as opposed to discussing issues which is not relevant to the student. Agenda control remains a key determinant of campaign effects because the candidate determines the principal yardsticks in which he/ she would be evaluated by the electorate as this are achieved through media communication. An extension in investigation of agenda control during campaign, Johnston et al 1992 argues that rhetoric also plays a special role by directing voters towards a specific agenda and considerations surrounding that agenda. This is achieved by the interplay of the acquisition of information and agenda control which provoke their voting decision. The evidence can be seen in their study of Canadian election 1988 which shows how free trade agreement between Canada and the United States, as a result of the candidates and parties rhetorical posturing came to the forefront of the public issue agenda To conclude the support for campaign, Kavanagh 1995 argues that the essence of campaign lies within itself, campaign is a means of choosing government and promoting political learning and citizenship, thereby contributing to the quality of representative democracy. This is because the interests of politics are heightened during campaigns through media communication about the candidate and party policies which are designed to attract the voting inclination for election participation. AGAINST CAMPAIGNS Examining the other view which argues that campaign do not matter, for the sake of clear understanding of the essay, the argument against campaign would be explored from the macro context factor of elections and their influence on voting behavoiur. As earlier stated, scholarly study on political science have argued the macro context of factors of elections both at the individual and aggregate level s strongly affect voting behavoiur and further posited that the macro context of election provides the wide platform in which any electoral campaign can function presenting a strong weakening interdependence characteristic of campaign. PARTISAN INDENTIFICATION Most predominantly stance of their argument is the influence of party identification on election outcome based on its psychological characteristics; their research argues that voting behavoiur and choices in elections are not merely a short term decision as similar the limited influencing experience campaign offers rather it is a conglomerate of certain long term political dispositions and ethnics in the social fabric of the electorate in which there is no room for campaign to change minds or influence behavoiur . An early voting research by Campell et al (1960) in their seminal book, The American Voter described the influence of party identification as a sustained psychological orientation to political parties which is a key determinant for attitude formation and political behaviour. Thus, electorates most often cast their votes based on their emotional affiliation with the electoral parties affirming their strong spirit of political devotion rather than the short persuasiveness of campaign propaganda. In the extensive study of the psychology of party identification and its influences of voting choice, a key realization is the existence of retrospective voting attitudes in the electorate. Fiorina(1981) explored the dynamics of retrospective voting and its direct impact of voting behavoiur as he argues that electorates associate their policy preferences with the policies of the party and make voting decision based on their retrospective evaluation of the performance of party in contrast to the mere make believe of campaigns. Much recent research points to the powerful electoral effects of incumbent performance evaluations which is termed the referendum model of presidential elections (Erikson 1989; Fiorina 1981) The recent studies such as Rice 1992 have evidently confirmed that election outcomes are easily explored without recognizing the mechanism of campaigning with their forecasting model. This simply means that elections outcome can be accurately predictive based on circumstantial factors before any campaign exercise. POWER OF INCUMBENCY Power of the incumbency is another factor that mitigates campaign effects. This particularly means that a party may enjoy a long term advantage in elections over its contemporaries because of its present governing authority. This long advantage may be due to the performance of the incumbency or possession of extensive resources to win the election. In this case, no matter the persuasiveness and aggressiveness of media fireworks in the campaign exercise, the ruling party would outage such approach. In all cases, every incumbency would strategically utilize all significant resources to ensure positive election outcome, they benefit from their ruling capacity in transforming media and economy to their advantage. In extreme cases, they use existing political institutions for election malpractices. A typical case is the Nigerias general elections of April 2007, Bratton (2008) which was characterized with rigging due to the power of incumbency by the ruling party (People Democratic Party) Trent and Friedenberg (2000) argue that the incumbency creates a special advantage for the candidate because of the political resources attached to the office of incumbency. Such advantage may be measured in them of the performance of the incumbency which may initiate retrospective loyalties during voting decision. In such power of incumbency, campaign may not necessarily affect the election outcome as voters would align their voting power t o the incumbency that have performed positively that an aspiring candidate of a new party STATE OF ECONOMY State of the Economy remains another significant factor subverts the effect of campaigns. Holbrook 1996 argues that the national economic context of political activities influences the voting behaviors, that is the economic performance of the incumbency largely influence voting behavoiur as voters are mostly inclined to vote for the ruling party in good economic times (High Gross Domestic Product, Infrastructural development)and more willing to change party in power in bad economic times(unemployment, inflation, high banking rate, poor exchange rate) . This position challenges the rhetoric of campaigns as it present comparison between the realistic experiences of the economy of the state and the fictitious gimmicks of campaigns. Thus, an aggressive campaign cannot influence the election outcome in occurrence of bad economic state A practical example cited by Holbrook 1996, was the American election of 1992, the winning of Clinton of the incumbent president George Bush was not due to his strong content of this campaign, it was purely because of poor economic situation of Bushs administration. No Bush campaign would have influence the voting behavior to change the experience of the realities o f the economy WEAKNESS OF CAMPAIGN ACTIVITIES Even though it is believed that the power of campaign lies in its events of activities, it have been characterized with several shortfalls ranging from its irrelevant key themes, ambiguous message and inappropriate media channel. Kavanagh 1995 also argues that the shortfalls of campaigns lies in itself as, campaign are mostly surveyed based on the content of output(advertisement, flyers) not by its output (election result).The lack of defined measurement system for campaign effect devalued its significance because election outcome is a product of several interplay of key factor and campaigns is least . Also he identified the ineffectiveness of campaign in various factors are wrong timing , conflict of electoral goals(election winning) versus other political goals(party values),Disagreement on campaign strategy and tactics ,Lack of party actors for implementation of campaign strategies, Lack of guaranteed knowledge about election winning. CONCLUSION Evaluating the two ideological perspectives on campaign, it may difficult to take a decisive position considering the continuous transformation of political environment. However, it is true that voters are open to myriad of political information designed to influence their voting decision but tend to make their voting choice based on their sociological experience, campaign seems to be one major political process that creates a platform of series of effects ranging from the reinforcement of the retrospective values, education of the voters political knowledge and influencing the voting behavoiur. The main paradox is the word matter in the question because relevance of campaign may be related to different objectives, context and ideologies. In order, campaign effects can be from different studies use different approaches to aim specific objectives. Therefore, it may be devaluing to adjudge a political act to be irrelevant if it does not achieve the entire expected objective. It is important to say that no political scholar can specifically say that a particular political activity guarantee the Election winning because Election outcome is a series of interplay of macro cultural actives, therefore campaign may matter but not necessarily to all voters

Romanticism Vs. Survival In Th :: essays research papers

An important theme in The Death of Artemio Cruz, by Calrlos Fuentes, was the comparison of romanticism and survival. This is shown through two important characters: Artemio Cruz, and his son Lorenzo. A romantic (Lorenzo) is a being that has ideals and fights for them. They know their goals and try to achieve them, while survivors have an only goal of keeping themselves alive. The survivors live through their choices and the romantics die as heroes, but each one complements the missing half of the other. Artemio Cruz is a typical survivor. He “knew how to fuck up other people and not get [himself] fucked over'; (PAGE 137). His choices allow him to survive and others to be killed. Although he lives through his choices, Fuentes shows through his interesting narrative device of expressing Cruz’s unconscious, thoughts and memories that he regrets and reflects upon while on his deathbed. When the second person narrator says that you “are going to live...You are going to be the meeting point, the universal order’s reason for being...Your body has a reason for being...Your life has a reason for being...You are, you will be, you were, the universe incarnate'; (PAGE 305), he is trying to show that everyone has a reason for living. Fuentes shows the reader why Artemio’s life is so important and why he believes that he is a model to the people. Artemio Cruz lives through his choices. He chooses to be a survivor, but each time he makes a choice, he leaves part of his romantic half behind since he saved himself instead of others. Instead of following his ideals, he follows his greed. He chooses to become rich and corrupt and to abandon his dreams, but he regrets doing a lot of those things because he killed many people in order to survive, including a part of himself. He said that he “could have died at Perales...with that soldier...I survived. You died'; (PAGE 236). After everything is passed, he stops to think about what he did wrong and regrets it, but at the time, he just cared about himself. When he went to war he met Regina and they started to have a relationship, but since he is a survivor, once again he saved himself. Regina got killed, but he didn’t. However, his son Lorenzo, has a completely different life story, but of the same importance.

Language Separation in Immigrant Families Essay -- Immigrants Immigrat

Public transportation Essay

This essay will focus on some of advantages and disadvantages of public transportation. First of all, I’d like to talk about advantages of public transportation. Using public transportation can reduce the number of people who drive their own car. It can ease traffic jam and improve road condition. We can also reduce air pollution by using public transportation. Public transportation can accommodate a lot of people and send them various destinations. It leads to the reduction of harmful emission gasses such as carbon dioxide. On the other hand, we have some disadvantages associated with public transportation. Using an automobile is more accessible than public transportation when we live in countryside. In most cases, there are few busses, trains and taxes in there. It’s very inconvenient for local people. If they have their own cars, they can drive anytime and anywhere. What’s more, it’s tough for elderly people to use public transportation. They have to go up and down the stairs when they use public transportation. There are many stations which don’t have elevators or escalators in Japan. In my opinion, I can’t live without public train because I can get to the office in time. At any rate, public transportation is essential for our daily life.

The challenge of food scarcity

Our world today is facing an extreme increase of food shortage and that happened when the food produce is not enough that can automatically threaten and shake the lives of millions of people, food scarcity could also be due to the rapidly rising human population that as a matter of fact Just had doubled over the year.Furthermore, the fact that we don't have any idea on what maximum number of people the world will continue to support and feed, that lead us to questioning if there is enough food for everyone in the future and a solution to end hunger and other problems that comes along with.Moreover, there are still many different reasons or factors of why people are starving in the different areas over the world, the lack of economic Justice and rising population are Just merely two examples out of them all and made people struggle to get enough food to eat. On the other hand, Majority of the globe's population especially the youth tends to Just ignore the issue of hunger, or are simp ly blindsided by events as today's economic crisis. We seem and tends to be a creatures f crisis.Rather than accepting the possibility that serious problems are Just over the horizon and is happening, we choose to look for any hope of positive information to ease our fears, but the fact is that hunger is a big problem in the world today and It is equally important that people should inform and get their selves involve on the issue about food scarcity so that they will know who are the ones truly suffering and the serious damage it does to those people.And also for them to avoid on wasting food, because all the extra food can't be Just given out to the needy and hungry entries, but if it could the government still don't have enough transportation and the money to send all those extra food to the suffering people. Every one of us must take food scarcity seriously because the solution for solving hunger and scarcity calls for the cooperation of everybody. Furthermore, As an Internation al student it is essential that we include world food hunger in our studies for it is directly interconnected on global politics and issues.For in International studies we educate ourselves and participates on programs of Globalization and development. Also, we must not only study but to also get ourselves involve in helping how to eradicate world hunger by helping in our own little ways those people and communities who are struggling with such problems that are cause by food shortage, for them to be able to develop ways to sustain their way of life, is the main goal of an International studies student. Remember Great things comes from small beginnings.To answer the questions why people are continuing to starve to death, we need to know first about the history of food production; how it contributes on the food we produce, goes the process of food production prohibit or even more promotes hunger? Second, we need to understand that the image that we get from the media can be very misl eading and sometimes not the truth and tends to show only a portion of what was really happening, so we must explore and research to be informed in the current reality so that we can come up and make better solutions.On the other hand, even if hunger is inevitable, we know, beyond any shadow of doubt, that there is a remedy for our world's situation and the earth can and able to feed its inhabitants. And there are many ways on how we can do it, like giving and improving aid and providing equipment and materials to the poor and underdeveloped countries needed for their agriculture, for these countries especially on the Global south, have the land and water to grow but they lack the knowledge, money and technology to make their resources fruitful.By also slowing the increasing of oil prices and usage of bio fuel so that the food price escalation can be somehow prevented because when the costs of essential foods rise, it can then dramatically affect those people who are lying on food p rices because bio fuels hurt the developing countries the most.Furthermore, the Government should promote and implement alternatives which don't disrupt the food supplies and if possible the Government should also increase the incomes of the poor instead so that they can buy their food, this is much better than keeping incomes and prices low. The solutions to the present crisis mention above can help eradicate food shortage and hunger and save the world at the same time, humanity must confront all the issues which can no longer be ignore because globally the effects will spread.

Mass Surveillance Essay

The affair began on June 17, 1972, when the local police arrested five men for breaking and entering into the Democratic National Committee headquarters at the Watergate complex. The police found on the burglars a slush fund used by the committee for the re-election of the President Richard Nixon and listening devices. They look secrets agents more than burglars. As Washington is a federal district, the affair was charged to the F. B. I. Within hours after that, the F. B. I discovered a name of a C. I. A officer in the address book of one of the burglars. The officer was a member of a secret operative team charged by the President to protect confidential documents inside the white house. Although the burglary seemed to be an operation led by former employees of the White House in order to spy on Democratic Party elections plans, the FBI investigation was not going away. The case was covered by the head of F. B. I Patrick Gray. Who was shortly before appointed by the President in place of J. Edgar Hoover (dead in May, 1972). The President had chosen his friend instead of William Mark Felt, the Bureau’s Associate Director, the second-ranking post in the F. B. I after Hoover. At first, the case made a very little noise and seemed to be covered up. Nixon reelected for another four years in November 1972. He defeated McGovern, the democratic leader, with over 60 percent of the popular vote. Until end of 1972, when the two Washington Post journalists: Bob Woodward and Carl Bernstein revealed the affair in public. They had been informed by an F. B. I whistleblower (he revealed himself in 2005 and he was William Mark Felt, the number two in the F. B. I at that moment). The affair was covered by many other media like Time Magazine, and The New York Times and they accused the President and his administration. Who also accused the media of making wild accusations, putting too much emphasis on this story. Months later, the affair had a dramatic consequents and political repercussions, an investigation conducted by the Senate with democratic majority. It was revealed that President Nixon had a tape-recording system in his office and he had recorded many conversations. Recordings from these tapes implicated the president revealing that he had known about the affair and had attempted to cover up. After a protracted round of bitter court battles, the U. S. Supreme Court unanimously ruled that the president had to hand over the tapes to government investigators, he ultimately handed over. Facing near-certain impeachment in the House of Representatives and a strong possibility of a conviction in the Senate, Nixon resigned the presidency on August 9, 1974. His successor, Gerald Ford, issued a pardon to him. The Watergate scandal resulted in 69 government officials being charged and 48 being found guilty like vice president, F. B. I head, C. I. A officers, and all members of president’s administration.
