Free Essays on Bernard Bass

Critique on the contribution of the transactional-transformational leadership paradigms of Bernard Bass to modern management thought and practice INTRODUCTION Transformational leadership, (TFN) was first distinguished from transactional leadership, (TCN) around 1973 by Downton. James Mc Gregor Burns, in the late 1970s, studying the histories of various political leaders, continued to redefine the differences in (TFN) leadership and (TCN) leadership. TFN leaders’ and followers’ purposes become fused, as both seek new ways of working with an objective, thus achieving more for both. TCN leaders engage with followers in a transaction that involves rewards (pay, promotion, etc) for the followers, for superior performance. (Burns, 1978) In â€Å"Factors of Transactional and Transformational Leadership†, Bass (1985) concludes that neither purely transactional nor purely transformational leadership style would result into subordinates’ performance beyond expectation. Analyses of various surveys make him suggest that a mixture of both provides the highest outcome. While theories since the 1980s widely assume that one leader has only one style, others analyses of the correlation between leadership behavior and employee motivation suggest that transformational leadership would drive higher achievement than transactional, Bass observes that one leader, mainly belonging to one of the two styles, might show attitudes of the other style as well based on contingencies. Ultimately Bass expanded upon the theories of Downton and Burns, and brought in several contributions of which the most notable are the four â€Å"I’s†, (Inspiration, Intellectual Stimulation, Individual Consideration, Charisma) and the Multi-Factor Leadership Questionnaire which helps determine the leader’s strengths and weaknesses in transformational leadership areas.

The effects of painkillers on the heartrate of a daphnia essays

The effects of painkillers on the heartrate of a daphnia essays Late one afternoon, a lady was driving home in the rush hour traffic. The last thing she needed was a pounding headache. While she was stopped, she dug in her purse for some aspirin to relieve her headache. She chugged it down with the Pepsi sitting by the seat. Her only worry was to relieve her headache. The affect of the painkiller on the other parts of her body was not a concern to her at that point in time. Should people wonder if their painkillers are affecting their body? Should people know how painkillers are affecting their heart, heart rate, or even worse, causing heart disease? It may just be the ingredients of a pill. Often the side effects of medication are discovered too late. Phentermine and fenfluramine are not only a diet pill ingredient but also causes heart valve problems. (Gorman 113) This is just one example of the things that may cause heart problems. They could also include an ingredient in a painkiller or other medications that a person could be taking. There are many different types of painkillers, the most common include Aspirin, Tylenol, and Ibuprofen. Aspirin, is used to relieve minor headaches, reduce fevers, colds, muscular aches, menstrual discomfort, toothaches and arthritis pain. Tylenol, is primarily for the relieve of minor aches and pains associated with headache, muscular aches, backache, minor arthritis pain, common cold, toothache, and menstrual cramps and for the reduction of fever. Ibuprofen, also relieves minor aches and pains due to colds, headaches, toothaches, and reduction of fevers. But yet, why may they affect the heart? The heart is found behind the breastbone. The heart is a hollow muscular organ that balances the circulation of blood. Blood then passes through four chambers that are separated by valves. Valves control the blood movement inside the heart. (Funk and Wagnals 273) What kinds of heart diseases are caused from painkillers...

United Arab Emirates Essay Example | Topics and Well Written Essays - 2000 words

United Arab Emirates - Essay Example United Arab Emirates The principal and the most prosperous of all of the seven states is the capital of the federation, the Abu Dhabi generating nearly sixty percent of the country’s wealth. The most popular city from the federation, Dubai City is located in the Dubai Emirate, the second leading emirate while Sharjah City and Khawr Fakkan are the two main cities in the third biggest state, the Sharjah. The UAE consists of tribal groupings of Arabian Peninsula sheikhdoms found on the tip end of the Persian Gulf and north the Gulf of Oman, the area was involved in several dynastic clashes for centuries just immediately after it was converted to Islam in the seventh century. The main tribal groups of the country’s nationals are the Qawasim and the Bani Yas who emerged as the powerful tribes after the dynastic disputes. The Qawasim were originally traders and inhabit the present day emirates of Ras al Khaymah while the Bani Yas were predominantly agriculturalists and pastoralists and lived in what is today the emirates of Abu Dhabi and Dubai. The British mounted expeditions against the inhabitants in an attempt to have control of the maritime routes and a desire to establish supremacy in the area over other interested European powers. However, regular warfare among tribes was still rampant at sea and the sheikhs made several truce agreements with the supervision of British political authorities to whom the warring parties reported any violations of the truce treaty. A perpetual maritime truce was signed by the tribal sheikhs in May 1853 to end any further conflicts at sea between the tribes. The coastal sheikhdoms thereafter remained under British protection practicing their traditional form of Arab monarchial rule while Britain oversaw their defense and foreign relations. In 1952 under the guidance of Britain, the seven sheikdoms established the Trucial Council to advance the implementation of common policies concerning administration of the sheikhdoms with the aim of eventually leading to a federation of emirates. In 1968, Britain decided to end the protection status with the seven sheikhdoms and withdrew United Kingdom armed forces out of the region. Three months thereafter, the seven sheikhdoms formed a Federa tion of Arab Emirates together with Qatar and Bahrain, still under British rule. However, in 1971 the latter two states decided to cede from the federation to establish separate sovereign states. Immediately after in the same year, Abu Dhabi, Ajman, Al Fujayrah, Dubai, Sharjah and Umm al Qaywayn agreed to have a common federal constitution in order to achieve independence under the United Arab Emirates. On December 1, 1971, Britain ended all ties and relationships with the seven sheikhdoms including every one the treaties and declared the federation independent on December 2, 1971. Initially the six emirates formed the federation and the other remaining sheikhdom, Ras al Khayman, joined the United Arab Emirates in February 1972. When independence was declared, Sheikh Zayid of Abu Dhabi assumed the presidency of new UAE until 2004 when he died while Sheikh Rashid Al Maktum of Dubai was entitled the vice president and his son Sheikh Maktum ibn Rashid Al Maktum was named the prime mini ster.

Mountain Dew Research Paper Example | Topics and Well Written Essays - 1750 words

Mountain Dew - Research Paper Example Second, the company's flagship advertising campaign, "Do the Dew," is now in its eighth year. In that period, competitors have had ample time to copy many of the once-distinctive elements of the marketing strategy and erode the freshness, as well as the impact, of the primary campaign and any pool-outs. This analysis will present these issues using a SWOT approach to focus on the significant issues of the case. Analysis. The managers responsible for marketing the Mountain Dew brand are in a difficult place; they are not dealing with a new product entry, but are responsible for maintaining the brand's place at the top. The brand's advantages include the very things that have made them successful so far, but they still face several challenges. Even though their brand health indicators remain strong, the brand is almost certain to lose market share without some proactive and effective changes. As shown in the SWOT analysis in Table 1, the brand enjoys some key strengths and good opportunities, but the Mountain Dew product is not without its weaknesses, and it is exposed to some potentially serious threats if management can't tune its position and get sales back on track. Table 1 Strengths Weaknesses Opportunities Threats Brand Recognition Image Saturation Re-engage primary market Non-Carbonated Products Corporate Resources Loss of Niche Branding Enhance Brand Health Advocacy Marketing Commitment -- Super Bowl Ads -- The market has a strong recognition of this brand, and the marketing efforts have been successful in making product perception match market trends. That success, however, is now creating difficulty as the market is trending away from the very image the brand has been building for the past eight years. Further, the competition has co-opted many elements of the image and the market is virtually saturated with alternative sports, music, and young faces. Additionally, the traditional cola market is eroding as it looses market share to non-carbonated, alternative beverages. The idea of having a "kick" which is derived from sugar and caffeine successfully played to the cool generation, but the counterculture demographic is more likely to see those compounds as unhealthy. Nevertheless, products like Red Bull show that there is still a strong market for such products. The corporate resources that a company like PepsiCo can bring to bear on the marketing are certainly a strength; but just bec ause a company can speak broadly doesn't free it from needing to have something significant to say. As the product begins to loose its distinctive niche branding to better-positioned offerings, management has the opportunity to recapture its core constituency and enhance the brand; but the new creative is going to have to move beyond skateboards and rock music. The marketing commitment shown by PepsiCo, particularly the prohibitively expensive Super Bowl ads, is both a key strength and opportunity. The message those strategies deliver, however, is the main thing. Alternatives. Management has three fundamental

Evaluating Art Throughout The Ages Essay Example for Free

Evaluating Art Throughout The Ages Essay Throughout the history of art, evaluation of artistic works has continued even long after the artist’s lifetime. This is because the proper evaluation of any work of art involves an understanding of its cultural and historical context, its philosophy and the message the artist tries to convey. Although beauty (aesthetics) used to be an important component of art evaluation, post-modern and abstract art have delegated it to obscurity. (Schaeffer) Below are some criteria relevant to evaluating art from any period of history : 1. Technical quality and brilliance : These consist of form (structure and expression), contrast (separation of object from background in many instances), texture, colour display or the use of lines (in line art), composition of various objects in the artwork and quality of craftsmanship. 2. Artistic integrity and vision : Artists should remain true to their worldview and to themselves. This means not only uniqueness and originality, but also remaining committed to the ideal and style he is trying to depict. 3. Philosophy and world view : This is often referred to the work’s hidden meaning, and the values it represents. E. g. in prehistoric cave art, the world view would often be related to the day-to-day wish fulfilment of bountiful hunting. Salvador Dali’s artistic philosophy was based on surrealism ( attached picture ), which often had a dream-like quality. 4. Relation to the artist’s life’s work, its genre and period in history : Many of these qualities cannot be completely evaluated during the artist’s life time, and may require significant periods of time after its completion. In many cases it is never complete e. g. masterpieces like the Mona Lisa continue to be evaluated, centuries after it was finished. Reference : Schaeffer Francis (1978). Art and the Bible. Figure. Salvador Dali’s ‘Dream of a Virgin’ depicts his surrealistic philosophy, and a dream state.

The Bluest Eye by Toni Morisson :: Toni Morisson The Bluest Eye

Toni Morisson's novel The Bluest Eye is about the life of the Breedlove family who resides in Lorain, Ohio, in the late 1930s. This family consists of the mother Pauline, the father Cholly, the son Sammy, and the daughter Pecola. The novel's focal point is the daughter, an eleven-year-old Black girl who is trying to conquer a bout with self-hatred. Everyday she encounters racism, not just from white people, but mostly from her own race. In their eyes she is much too dark, and the darkness of her skin somehow implies that she is inferior, and according to everyone else, her skin makes her even "uglier." She feels she can overcome this battle of self-hatred by obtaining blue eyes, but not just any blue. She wants the bluest eye. Morrison is able to use her critical eye to reveal to the reader the evil that is caused by a society that is indoctrinated by the inherent goodness and beauty of whiteness and the ugliness of blackness. She uses many different writing tools to depict how "white" beliefs have dominated American and African American culture. The narrative structure of The Bluest Eye is important in revealing just how pervasive and destructive social racism is. Narration in novel comes from several sources. Much of the narration comes from Claudia MacTeer as a nine year old child, but Morrison also gives the reader the insight of Claudia reflecting on the story as an adult, some first person narration from Pecola's mother, and narration by Morrison herself as an omniscient narrator. Pecola's experiences would have less meaning coming from Pecola herself because a total and complete victim would be an unreliable narrator, unwilling or unable to relate the actual circumstances of that year. Claudia, from her youthful innocence, is able to see and relate how the other characters, especially Pecola, idolize the "ideal" of beauty presented by white, blue-eyed movie stars like little Shirley Temple. In addition to narrative structure, the structure and composition of the novel itself help to illustrate how much and for how long white ideas of family and home have been forced into black culture. Instead of conventional chapters and sections, The Bluest Eye is broken up into seasons, fall, winter, spring, and summer. This type of organization suggests that the events described in The Bluest Eye have occurred before, and will occur again. This kind of cycle suggests that there is notion that there is no escape from the cycle of life that Breedloves and MacTeer live in.

The House on Mango Street Reflection Paper

February 6, 2013Cynthia Cotto [email  protected] edu Response Paper In the very first vignette Esperanza discusses how her family moved around a lot and even though the house on Mango Street was not the house of their dreams, it was a great achievement to own it. Although Esperanza knew they were not moving anytime soon, she recognized one advantage; her family was free of landlord management. In my community home ownership is a constant battle and for many simply a dream.I learn the value of home ownership in a similar sequence as Esperanza. My little sister and I were moved to and from apartment to family member’s houses until our first small home. A home with no back yard and only four stairs and side walk out front. None the less, a home to call our own; it was then that I knew one day I will own my home painted â€Å"white with trees around it, a great big yard and grass growing without a fence. † Setting this goal meant one thing to me, out; out of Philadelphia like out of the House on Mango Street.How to get out and leave my home, my Philadelphia that is so much a part of my maturing process that has molded who I am today is the challenge. Poverty is the drive behind my force on getting out, like Esperanza, poverty is a constant scene that drives my motivation to rise out from my community in Philadelphia. For many families it is not unusual to live in a row home next to an abandoned home or open lot where houses use to be; look around and see no grass only concrete, see no trees only stumps of where trees use to be and garbage carried by the wind collected alongside stoop of houses.The tricky part of growing up with this experience is realizing it molds character and influences a sense of direction. My experience in poverty directed my ambition in education therefore strengthening my chances in attaining my goals. Ultimately what was said to Esperanza by the three sisters, â€Å"You can’t erase what you know. You can’t for get who you are† is valid in the sense that no matter which path one is headed, their past is part of who they are, it is where they have been.Even though leaving Philadelphia is a dream of mine, I know there is no other place in the world I would rather be from; it has prepared me to be brave and define what I desire for my life and what is undesired for my life. Self-exploration is hindered in this book and my life. I can very much identify with Esperanza perspectives on societal issues that Latin women face. A society dominated by men and women relying on them, whether it is a father, spouse or friend. Men are considered the strong reasonable as where women are weak and emotional, in turn women need men for protection.A young girl may have two story paths, one where she relies on the protection of her father while she watches her mother cater to him or two, witnesses the struggles of a single young woman and absence for a father. This book describes marriage as priority for every girl or else how could she survive; appearances and physical features are highly valued traits. This attitude is not one that Esperanza agrees with, nor do I. For example, Marin she is the girl standing on the street just â€Å"waiting for a car to stop, a star to fall, someone to change her life. This character implies that she does not dream of actively setting life goals for herself and working to earn them, instead she will wait until a man makes it happen for her. The ideology behind this thought being that as a woman she must thrive to be as attractive as possible to heighten her chances of marriage and acquire worthiness. First women are to become wives, then mothers this is to be success enough. The thought of a woman exploring her independence not only from her family but from men is not an appreciated ideal.Esperanza mentions many women that are prisoners in their marriages and trapped in their homes due to such bias. This is an important issue and should be addres sed because reflecting on Esperanza’s perspective and my personal opinion; Latin women are not encouraged to explore independence much less through education. Sally is a great example that can express my reason for writing about this issue, her father sheltered her all her life and she married before eighth grade.Practicing those societal values leads Sally’s life to be encaged by her husband and home accompanied by nothing but the things she owns; this to which Esperanza understands that even though Sally has all the material things that her husband can buy, that is not worth much if there is nothing to do, no social interactions, or no self-respect. Esperanza absorbs her surroundings, contemplates her neighbor’s situations and visualizes her life and the thought of her life sadly gazing out of a window, this was all the motivation she needed to decide that she will not be end her story in the same manner; this I have done throughout my life as well.Being born and raised in the heart of Philadelphia I am consistently expose to the abundance of inequality, injustice and overall hardships that seem to walk hand in hand with this territory and culture of my community. Esperanza introduces Alicia, a girl that has a strong quality in common with Esperanza as well as I; the virtue of education. Alicia’s circumstances are very relatable to young Latin girls today in my life for example, I can recall positive reinforcement when I received good grades but there was rarely any encouragement to have me participate in extracurricular activities or educations competitions because there were chores.My family believed the transition would be easier if I did not move away for college and so I did not; I am encouraged to live home until marriage, therefore I have been. Things such as living on my own is addressed with the attitude of â€Å"why waste money, you minus well wait until you get married to move out,† but my education is my future; it is my gateway out of Philadelphia and into the path of my home with trees and grass to come home to after a day with my second grade students. With independence from my family and men is born a woman that can support herself and does not need to rely on a man.I am writing about the inequities regarding Latin women addressed in this novel as it is connected to my life. I like Esperanza, refuse to accept the limitations surrounding me like fog in the night discouraging me to pursue new paths. Most of the women characters Esperanza describe have strong personalities yet are unable to escape from their suppressing community and culture. I am neighbors with Mothers the age of fifth-teen and grandmothers the age of thirty-two. There are women that are raising their grand-children and mothers hoping to complete high school.Yet somehow this has become a norm it is not surprising to see a Latin woman have children at a young age as well as marriage. I personally never get tired of being asked: Do you have children? Are you married? You are in school? (in a very sarcastic tone); in that specific order. The expectations in this novel for young Latin girls are to find a man to support them and the way to find a man is through physically looking as attractive as she can and in order to become a loyal wife and mother. This is a society where a woman leaving their families to seek self-identification is not a natural thought.Esperanza was strong enough to fight through the society norm and pursue her talent and not become trapped in a house ruled by a man. Today I fight the same battle as do many Latin women do, we are strong and it takes bravery to go after one’s happiness in life. We strive to rise above poverty and community inequities through hard work and self-dedication to one’s ambitions. As The House on Mango Street is part of Esperanza, my Philadelphia community is part of me; without what I have seen I would be blind to what I want.

Reflection Summary Essay

The previous week’s objectives covered PowerPoint in Microsoft Office, Presentation Tools, and System Development Life Cycle (SDLC). What could be applicable to your workplace or personal, and how your knowledge has increased as a result of what you experienced through the learning activities. We learned about presentation tools that are available in the marketplace and their advantages and disadvantages that they may have. Our team agreed that Microsoft Power Point is the most common and most used in the workplace and market place. We were all very familiar with how the system works, we all have worked with Power Point before. We were all very comfortable with Microsoft Power Point. There are many other presentation tools that can be used, and that are available but overall the most common is Microsoft Power Point. The next topic we had discussed was about what business go through to implement new technology. The second discussion question posted we learned was in regards to six stages of the systems development life cycle. The system development life cycle (SDLC) has six processes in which information system is process: systems investigation, system analysis, systems design, programming and testing, implementation, and operation and maintenance. These six processes are important for organizations to use when deciding on an information system; however, these processes are not only for organization, but also for personal use as well. When deciding whether to get a new operation system for a personal computer, you can have some of the same challenges. Consumers have to decide what kind of budget they have, what will the system do for them, and will the system last for a long time before having to get another system. We didn’t realize what business have to go through to implement new technology into the business plan. We learned that it can be a very long, in depth and costly process to implement a new system in the work place. In conclusion, we have learned many great things as a team about Microsoft power point, and presentation. How everyone uses power point for work and personal life. We also learned about System Development Life Cycle (SDLC). How the process can be long and expensive depending on the system  requirements. We agreed and disagreed on many things but in the end we were able to learn from one another. Working as team has made it better and easier to learn, we each collaborated on putting this reflection summary together. It has made it an even better learning experience working together as a team.

Federalists vs. Anti-Federalists Essays - James Madison, Free Essays

Federalists vs. Anti-Federalists Essays - James Madison, Free Essays Federalists vs. Anti-Federalists Federalists vs. Anti-Federalists Most people think that the U.S. constitution was just ratified and there was no arguments over its passing. In fact there was almost enough opposition that it came very close to not being passed. It was the Hamiltonians vs. the Jeffersonians in almost all cases. Even before the United States Constitution was ratified there was debate over whether or not to have a strict interpretation or a loose one. There was also debate over a States right to nullify a law. As memories of Shays rebellion and the reality of the Whiskey rebellion came to the front the issue of undue force became an issue. One of the other major issues during this era was the debt and the national bank. Although the constitution was passed there was much debate over whether it should be a strict or loose interpretation. Hamiltons federalists thought it should be loose and Jeffersons democratic-republicans strict. If it was strict then the federal government would only have the powers specifically given to it because of the tenth amendment. Too justify it being loose the federalists used the elastic clause (Article 1, Section 8, Clause 18) and then they could decide what was necessary and proper. Hamilton thought that the only way to protect states sovereignty and at the same time have a national government would be to have a strong central authority. The Kentucky and Virginia resolutions brought to the front a very important matter of concern, a states right to nullify a law. The federalists said that if a state could nullify a law then what did the laws mean. The democratic-republicans thought that if a law hurt a state unduly then it could be nullified. Resolved, the Kentucky Legislature declared in its opening paragraph, that whensoever the General Government assumes undelegated powers, its acts are unauthoritative, void, and of no force. Supreme authority in America, it argued, was held not by the federal government but by the people and the states, and Congress and the president had only those powers clearly delegated to them by the Constitution. This issue would not be settled until the civil war This is one of the pivotal moments of politics at that time the federalists were thrown out in 1800 mainly because of this. Another cause for concern about the new government was the use of undue force. The democratic-republicans thought that Washington used too much force in putting down the whiskey rebellion. He used 12,950 men to put down that rebellion or the so-called insurrection as he called it. Washington did another thing to anger the democratic-republicans when he left Hamilton in charge or making the arrests. They thought that that was too much force for people who in their mind had good reason to rebel. The federalists thought that this was a good move. They based this on what happened with Shays rebellion. After the ratification of the U.S. Constitution the debt became an issue. The United States all told owed 54,000,000 and the States debts were 21,500,000. Hamilton came up with a brilliant plan to help pay off the debt. He would sell bonds to pay it off and keep the debt solely owed to the citizens of the U.S. Thus the only burden to the taxpayers would be the interest on the bonds, which would actually go back to the people. The Jeffersonians opposed this not because they doubted that it would work but because they thought that those who deserved the least would make the most. They were referring to the speculators who had purchased the papers at below their value. Also part of this plan was the bank of the United States. The bank was a good idea but too reminiscent of the Bank of England which some believed had caused England to be so harsh. The Jeffersonian and the Hamiltonians disagreed on almost every issue. There arguments can almost all be traced back to states rights vs. a strong central government. Although they agreed on some issues those were few and far between. These two parties would be the dominant force in politics for the next few decades.

Radioactive Tracer Definition

Radioactive Tracer Definition A radioactive tracer is a radioactive element or compound added to material to monitor the materials distribution as it progresses through a system. The use of a radioactive tracer is called radiolabeling, which is one form of isotopic labeling. Radioactive Tracer Uses Radioactive tracers form the basis of some medical imaging systems, such as PET scans. Radiolabeling is used in research to trace the path of elements in biochemical reactions and cells. Radioisotopes are also used to track the flow of fluids, particularly in the petroleum and natural gas industry. Examples of Radioactive Tracers Usually, the isotopes chosen for use as radioactive tracers have a short half life. Thus, they are produced via nuclear reactions. Examples of commonly used radioactive tracers include tritium, carbon-11, carbon-14, oxygen-15, fluorine-18, phosphorus-32, sulfur-35, technetium-99, iodine-123, and gallium-67. Sources Fowler, J.

Concrete Repair, Rehabilitation Essay Example | Topics and Well Written Essays - 1000 words

Concrete Repair, Rehabilitation - Essay Example There are some published works concerning the influence of roughness and moisture properties of the substrate surface on the bond strength with added layer. But, most works concentrate only on one characteristic of roughness or moisture or test method etc., at one time. Further, roughness is assessed only qualitatively, by observing the substrate surface and by classifying it as very smooth, smooth, rough. In the Eurocode 2 (Eurocode 2, 2003) it is stated that for shear at interface between concrete cast at different times, "in the absence of more detailed information, surfaces may be classified as very smooth, smooth, rough or indented". This kind of roughness evaluation has disadvantage due to subjective results. Thus, this dissertation aims to carry out an experimental study for evaluating the effect of different surface conditions on the bond between two concretes and to compare the effects of different roughness conditions relative to quantified roughness parameters. It is antic ipated that with this study, a suitable condition for substrate surface for optimum bond will be established. The researcher wishes to convey his profound gratitude and sincerest appreciation to those who have extended much effort and assistance contributory to the success of the dissertation. His deepest indebtedness goes particularly to the following: Almighty God, for giving him strength, wisdom, and vision to finish his study; His Supervisor, for his guidance and suggestions to improve the research work; His family, who reassured, inspired, and supported him morally, and financially; His colleague and friends, for their words of encouragement; All others who helped the researcher make this dissertation possible.

With time, however, concrete structures deteriorate and weaken, thus repair and restructuring is inevitable. Signs of deterioration or defects such as cracks on the structures are often perceived as indicators of the need to perform maintenance. Concrete repairs usually require adding of new concrete to existing old concrete element to protract the 'useful life of an existing structure, to restore its load-carrying capacity and stiffness, and to strengthen its members' (Bissonnette, et al., 2009). Some of the most commonly used cementing materials in the production of the new overlay include resin, mortar, mortar purified with latex, ordinary concrete (OC),

The Theoretical Underpinnings Pertaining To Self-Harm Research Paper

The Theoretical Underpinnings Pertaining To Self-Harm - Research Paper Example This research will begin with the definition of self-harm as acts committed deliberately with the purpose of inflicting injury or damage to one’s self. D’Onofrio argued that despite the fact that 1 out of 100 Americans inflict harm on themselves as a way to cope with stress, the subject remains taboo and is perceived by others as deviant behavior. This is proven by the social stigma instigated by medical professionals and lay people alike. In medical terms, self-inflicted violence or self-mutilation is characterized by committing harm to one’s self to the extent of causing considerable tissue damage or visible marks which persist for days. The following paragraphs discuss the theoretical underpinnings pertaining to self-harm: Self-harm is different from acts which are considered suicidal, ritualistic, sexual, or ornamental. Individuals who perform self-harm usually get treated by physicians and mental health professionals. However, treatments provided to these in dividuals apparently does more harm than good due to social stigma and the lack of self-harm information available to medical and mental health practitioners. For clarification on the concept of self-harm, Gratz and Chapman provided the following characteristics: (1) self-harm is done on purpose without intent of killing one’s self; (2) physical injury inflicted is instantaneous; (3) self-harm is perceived as a type of coping mechanism; (4) self-harm may be committed by anyone regardless of gender, race, ethnicity, or social class; (5) self-harm is committed by individuals with psychiatric disorders, as well as high school and college students; and (6) incidents of self-harm become less as people get older. Gratz and Chapman devised a checklist for gauging risk factors of self-harm. The checklist is divided into three categories: (1) impulsivity; (2) neuroticism or negative emotions; and (3) childhood experiences.
