Frederick Douglass Teachings And Triumphs - 2401 Words

Lamese Khoury Professor Natalia Menendez English 1B 25W 4 February 2015 Frederick Douglass’ Teachings and Triumphs: Racism, which still thrives in areas across the United States, was an epidemic in the antebellum south. The basis of the system of slavery is that skin color determined worth. Conveniently, for America’s southern, white population, blacks were only fit to be sold and bought for unpaid service. The prejudice driven consensus among the southern white population was that a black person was nothing more than an ignorant brute. For the oppressors, this was enough to justify the atrocious act of owning another human being as property. In his eloquent autobiography, Narrative of the Life of Frederick Douglass, An American Slave, Written by Himself, not only does Frederick Douglass negate this presumption, he establishes who the real brute is. Within his candor, he stresses how destructive this pervasive mentality was for the victimized slave. Religious and proudly moral, masters often boasted their savage and cruel nature by aggressively overworking, starving, depriving, beating, and raping their slaves. Moreover, black slaves often emanated the good of mankind. If they could not always resist the orders of their masters, they could at least resist the complete suffocation of injustice by devoutly caring for and loving one another. Resistance, regardless of it’s manifestation, was no simple feat for a slave during the tyrannical era of the American slave system.Show MoreRelatedAnalysis Of Frederick Douglass s Learning On Read And Write 999 Words   |  4 PagesIn Frederick Douglass s essay, Learning to Read and Write, he describes the various methods with which he became literate throughout the age of slavery.

Essay on Alzheimers Disease - 512 Words

Even in a world of modern medicine and major medical advancements like the world has never seen before, some diseases still continue to plague the human race and confuse even some of the brightest scientists today. Unfortunately, Alzheimer Disease (AD) is one of them and it affects between 2.4 and 4.5 million people in America. Alzheimer’s is usually diagnosed in people over the age of 65, but in rarer cases people as young as 16 have it. Since it is a degenerative disease, patients develop it with few symptoms at an earlier stage, but then it gradually becomes more predominant in how the patient lives his or her life, developing into dementia â ¨ ¥. Alzheimer’s Disease was discovered by a neurologist named Dr. Alois Alzheimer in 1906.†¦show more content†¦In 1907; however, he identified an â€Å"unusual disease† that caused memory loss, disorientation, and hallucinations. Dr. Alois Alzheimer called it presenile dementia, while Emil Kraepelin named fam iliarly as, Alzheimer Disease*. While Alzheimer’s Disease is usually diagnosed to patients over the age of 60, sometimes people much younger tend to discover they have Familial Alzheimer Disease or FAD. Familiar Alzheimers is inherited through dominant autosomes and must have a parent who had AD. Alzheimer’s is known to affect at least three genes: Presenilin 1 (PSEN1), Presenilin 2 (PSEN2), and Amyloid beta (A4) precursor protein (APP)â ¨ ¥. It is believed that Familial Alzheimer’s affects chromosome 1, 14, and 21 causing abnormal proteins to be formed⊠£. On chromosome 21, mutations form causing the formation of APP, chromosome 14 causes PSEN1, and chromosome 1 causes a mutation forming PSEN2.â ¦ ¶ Common symptoms of Alzheimer Disease are minor memory loss that soon progress over time, being unable to recognize names and objects, restlessness, agitated mood, and not being able to speak correctly are all common symptoms of Alzheimer’s Disease.

Management of Change in Multinational Firms-Samples for Students

Question: Prepare a report that Critically Evaluates the utility of Theoretical Models of change for executives who are looking to transform ways of working within their Multinational Firms. Answer: Introduction With the technological advancements and adoption in the global business arena, diversity management is a vital aspect that should be adopted by a company with the aim of remaining effective in the competitive global market. In a systematic review, Shah, Hasnu, and Butt (2016) point out that any local, regional, or international firm seeking to succeed in business should embrace diversity toward their business thinking, strategies, styles of leadership, as well as in their business activities and innovation strategies. The same study denotes that diversity is no longer on making numbers but is focused on how the organization authentically treats its stakeholders down the foundation of the business model adopted. As a result, diversity has become a time-sensitive imperative in the current business environment. This paper hence seeks to evaluate the theoretical models of change that can be adopted by business executives with the aim of transforming ways of working within their multinati onal firms to meet the desired business goals. Background information on diversity and the nature of the international business Recognizing the need for diversity in a workforce is a value that is expected of all company executives and leaders. In a systematic study, Akinyi (2011) points out that the ongoing process of globalization in the social, political, and economic facets have led to the significant increase in the cross-cultural interpersonal contract. In other words, intensified internationalization in the global economic arena has been achieved through joint ventures, alliance as well as acquisition and cross-border mergers as pointed out by Hamraz, Caldwell, Wynn, and Clarkson (2013, p. 676). The same study denotes that top most global organizations all across the world are made up of cultural and ethnic differences within the working environment. It is because business managers and executives have realized the importance of making a business environment broad and diverse to effectively reach the target customers. As a result, Masiero and Campomar (2016) point out that globalizing a diverse populati on requires a very intellectual dialogue all across the workforce to ensure effective change in productivity and performance in the business is realized. As a result, many studies recommend the adoption of proven and effective theoretical models that can effect change in both regional and multinational firms. However, the scope of this paper will focus on multinational firms only. Theoretical models of change for multinational firms Lewins Model Lewins Model is a change management model that is known for its popularity and efficiency when adopted both locally and internationally in the business management processes. The model was developed by Kurt Lewin, a physicist and social scientist who used the changing states of an ice block to explain the organizational and structural change (Lindberg 2013). In his study, Lewin observed that a block of ice cube has the ability to change its physical states from the solid form to the liquid form through a process known as unfreezing, also called melting in the modern science. At the liquid state, it is very easy to control it into the shape one desires, and this is the stage referred to like the change stage. The new form solidifies into the required shape through a process known as freezing. The model consists of three steps that are unfreezing, change and the freezing stage. In a systematic study, Lapatinas (2015) points out that the Lewins model has been adopted as a management strategy by many international executives with the aim of transforming the performance of the workforce as well as the overall organizational performance. In adopting the model, the study denotes that the management always starts by preparing people of the changes that are coming, a stage known as unfreezing. For instance, the international business arena is characterized by diversity in culture, language, race, taste and preferences, and lifestyle among other vital business aspects of diversity as pointed out by Luo and Jiang (2014, p. 134). The unfreezing stage is the initial stage that consists of the psychological preparation of the employees of the change in an organization. In other words, using the model as a tool of change requires the organization to ensure it practices regular and proper training and development on issues that can directly or indirectly impact change. It involves of breaking the current culture and building the new future culture that is projected to be effective in achieving the target goals and objectives of the company according to Lapatinas (2015, p. 427). Therefore, the training the workforce of essential aspects of diversity in business will enable them to evaluate and understand that the existing culture cannot continue propelling the company to its future success and must be changed in accordance with the nature of the international business arena. At this stage, the need for the change is determined by surveying the current status of the organization and understanding the main reasons why the change as to take place. In a systematic study, Akinyi (2011) points out that the change leader must also understand the doubts and concerns of the change and ensure that there is strong support from the senior leadership. The change stage is where the main action takes place after removing the uncertainties from their minds. It usua lly takes longer period since many people take much and different time to embrace and adapt to any change. For the success of the change, real leadership is very paramount to steer forward the successful adoption of the model as it involves numerous communications steps on the beneficial factors of the intended change. This is through dispelling any rumors of biases through honesty and being open and giving everyone in the company opportunity to participate hence creating empowerment among the staffs. Refreezing is the last stage, where by the organization internalize and institutionalize the aspects of the change. At this juncture, the company ensures that the aspects of the changes are used all the time with all the confident and stable employees. Therefore, the leaders should make sure that they create a feedback system to enable them to collect any concerns and reactions of the employees. These feedbacks will assist them to act appropriately to any resistance or any challenge to the implementation. They should also realize the short-term wins and reward them to motivate more employees to adopt and embrace the change. ADKAR Model ADKAR model is an abbreviation that stands for various aspects of change in organizational management. These include 1) Awareness of the need for change, 2) Desire for the change, 3) Knowledge about the change, 4) Ability to adapt and incorporate the change and 5) Reinforcement of the change into action (Van Sun 2011, p.64). ADKAR is a goal oriented model which focuses on the steps taken to acquire a particular purpose concerning an individual to achieve the organizational goal. The model aims at making everyone to understand that change happens at the individual level within an organization since most of the employees tend to be rigid to change and are easily associated with the negative side of change as pointed out by Luo and Jiang (2014, p. 138). In other words, it is necessary that every organizational manager with the focus on international business success should create awareness of the change to the employees. Van and Sun (2011) point out that this can effectively be achieved by proper communication to the employees while taking time to positively respond to their concerns with honesty and openness based on the reality of the international business. The leaders make sure that the information passed is connected to the individual and company benefits, an aspect that will help the employees to focus on working towards change for the benefit of the organization as well as their profession. For example, Google Inc, conducted a one-week departmental training to ensure that the employees were convinced on the need of change to a more effective and updated software that could globally be adopted to change the global business arena. With the help of its motivated and able engineers, the company was able to develop different accou nting systems that have since been adopted in almost every large business globally according to Lindberg (2013, p. 3). In other words, it was easy to achieve since the management created the desire for participation from each employee in the change process by explaining the roles of each employees roles and duties. The process should be through one-on-one communication with the employee, a strategy that can enable the management to read the reactions and concerns of each employee which can then be addressed in the process of change to ensure everyone is motivated towards achieving the set goals. The change management leader disseminates all information that is required to make the change through a knowledge-building program. The change program should only be after achieving awareness and desire for change from the employees otherwise the staffs will be less concerned with the knowledge-building process. The knowledge-building process is achieved through training, experience, and mentoring as pointed out by Enderwick (2011, p. 89). Adopting the model hence help the change management leader to determine and identify the ability of every individual in their performance on respective tasks and allocate a duty that each employee can do best to achieve the desired change. After the achieving the ability reinforcement, the leaders reinforce the change into action by averting the employees from the old habits into the new ones. However, adopting the model requires the management to ensure that there is enough time for the process since people are always slow and tend to be very rigid when it comes to change. ADKAR model can thus be adopted in a multinational organization with the aim of effectively planning for any change through diagnosing the failure of the current situation and creating the need for that particular change. Kotter Model Kotter Model is an-eight step process framework adopted with the aim of ensuring effective organizational change as pointed out by Shiliro (2012). The same study denotes that model was created by John Kotter, who believed that continuous innovativeness, technological and social-economic changes are the driving forces to help in ensuring an organization effectively adopts change strategies that can ensure it remains relevant in the competitive business market. The eight steps are; Creation of the sense of urgency that will result in the motivation of all staffs to do their work. At this stage, the change leader identifies the future situation of the company by examining the available opportunities that are exploitable. For instance, stiff competition, change in customer preferences, changing lifestyles, and technological innovations are some of the vital aspects that can help a manager strategize effectively on the need of change. The second step is forming a powerful coalition of the related persons and departments such as job status and experts who are emotionally committed to the change. In other words, Kotter Model suggest that driving an organization to change will require aspects like hiring motivational speakers and experts in specific areas that the organization would desire to focus their change. The third stage is the creation of the vision for change through linking all the ideas to make a clear one. The creation of a clear vision enables every participant to understand the reason behind the modification. Step four is a frequent and powerful communication of the change to all the people that will be impacted, by addressing honestly all the concerns raised. The fifth stage is the removal of any obstacle that might be on the way of the implementation such as identifying the resistance individuals and engaging them more suitable while rewarding those that embrace the change. The sixth stage is the crea tion of short-term wins that will help to motivate all persons to the main aim of the modification. The little achievements assist in reducing critics the seventh step is building for the change by increasing the number of the short-term wins. Through this, the success of the change can be determined as all the employees will have a focus on the best system to be adopted by the firm as well as the expected benefits as pointed out by Lindberg (2013, p. 3). The last step is the anchoring of the change in the companys culture by ensuring that every day and every personnel adhere to the new changes. In a systematic study, Grosse (2014) denotes that culture is a diversity aspect that directly affects the internal and external performance of an organization. For instance, the international business arena often involves different global businesses expanding into new markets with the aim of expanding their customer base. In the process, the employees should be well aware that there is a possibility of interacting with diverse individuals with different cultures towards the goods and services offered by the organization. As a result, adopting Kotter Model enables the organization to be prepared on cultural aspects that affect the performance of the business locally as well as in the international market. McKinsey 7s Model McKinsey 7s Model developed by Tom Peters, Robert Waterman and Julien Philips who were the McKinsey consultants in 1980s (Ravanfa 2015).The model has attracted academic practitioners in strategic planning since it addresses more on coordination than the structure in an organization. The model consists of 7 elements grouped into two categories that are hard and soft. The main aim of this model was to show how these seven elements can be brought into alignment with one another to achieve effectiveness in an organization. The hard elements are the core of the company that can be identified and influenced by the relevant stakeholders of an organization (Hanafizadeh Ravasan 2011, p. 30). The Hard elements are strategy, structure, and system, while, the soft elements, on the other hand, are difficult to describe and are always influenced by the culture rather than the management. The soft elements include style, staff, and skills and shared values. The strategy defines companys approaches that are well developed and articulated to enable it to achieve a competitive market share. All strategies, therefore, should align with the companys values, vision, and mission. The structure is the way a company subdivides into departments and represented by particular leaders from the most senior to the casual employee. Systems are the set procedures that control the daily activities and decision making in a company. Skills are the know-how and abilities of different employees in the firm. Staffs are the core of business; they are both the management and non-management personnel. Style refers on how the resources in a company are controlled to achieve the objective while Shared values represent the norms, values, and standard in the business that controls the actions of each employee. Both Waterman and Peters observed that for the success of the change, the leader must be able to identify all the elements that are not aligning. Then the com pany determines the best alignment of the elements and weather the modifications should be made and then doing the best action. The model is a procedural process that ensures success only when the all seven elements of the company are aligned correctly. Conclusion In conclusion, multinational firms tend to have business activities on two or more countries. In other words, the simple baseline is that such firms have production and sales operations in multiple countries. At the same time, the diversity in location of the business often comes with diversity in different aspects. They include the geographical conditions such as terrain, languages spoken by the people, culture of the target customers as well as their taste and preferences and lifestyles, and nature of the business suitable for such locations among other factors. However, not all international firms often succeed in their industry of operation, an aspect that forces other to operate under struggles that may lead to their closure when not timely monitored. Therefore, the management and executives of the international firms are required to equip their employees with the desire and need for change towards efficiency and sustainability of the organization when need arises. McKinsey 7s M odel, Kotter Model, ADKAR model, and Lewins Model can be adopted by multinational firms to ensure their business not only survive but become efficient and sustainable in their specific industry of operation.

Some of the behaviours associated with Oppositional Defiant Disorder can besides happen because the kid is undergoing a passage, is under emphasis, or is in the thick of a crisis. This makes the behavioural symptoms of Oppositional Defiant Disorder sometimes hard for parents to separate from the stress-related behaviours. In order for a kid to be diagnosed with Oppositional Defiant Disorder they have to be highly negative, hostile, and defiant in a changeless form for at least 6 months. This behaviour besides needs to be inordinate compared to what is typical for a kid at that age and disruptive to the household, school environments and normally directed toward an authorization figure. An illustration of an authorization figure would be parents, instructors, chief, or manager. The kid besides has to exhibit during these six months fou r or more of the undermentioned behavioral symptoms that are associated with Oppositional Defiant Disorder ; frequent pique fits, inordinate reasoning with grownups, sharply declining to follow with petitions and regulations, frequently oppugning the regulations, intentionally raging and upsetting others, frequently touchy or annoyed by others, faulting others for their errors, frequent effusions of choler and bitterness, or frequently vindictive or revengeful. Besides, the break must do important sum of harm to the kid s academic, occupational or societal operation and can non happen merely during a Psychotic or Mood Disorder episode. Last, the kid can non be diagnosed with Oppositional Defiant Disorder if they meet standards for Conduct Disorder, if the person is 18 old ages of age or older or run into standards for Antisocial Personality Disorder. Case Study My best friend has a boy with Oppositional Defiant Disorder. His name is Radon. Radon is ten old ages old and attends the 5th class. Radon s twenty-four hours normally starts out with reasoning about what he can and can non convey to school. His female parent and his instructor have now made out a written list of what these things are. Radon was conveying a computing machine to school and stating his instructor that his female parent said it was alright. At first his instructor wondered about this, but Radon seemed so credible. Then Radon brought a small knife. That led to a existent apprehension between the instructor and Radon s female parent. Radon does non travel to school on the coach. He gets teased and so retaliates instantly. Since it is impossible to oversee coach drives adequately, his parents and the school gave up and they drive him to school. It is still difficult to acquire him at that place on clip. As the clip to go forth attacks, he gets slower and slower. Now it is non rather as bad because for every minute he is tardily he loses a dime from his day-to-day allowance. Once at school, he normally gets into a small forcing with the other childs in those few proceedingss between his female parent s eyes and the instructor s. The category work does non travel that severely unless he has an episode as his female parent put it. Then he will toss desks, swear at the instructor, rupture up his work and garbage to make anything for the remainder of the twenty-four hours. The grounds for his effusions seem so fiddling, but to him they are the terminal of the universe. He is non allowed to travel to the bathroom by him self and at times this fusss him so he flips his desk. He was told to halt tapping his pencil, so he swore at the instructor. These types of things happen throughout the twenty-four hours harmonizing to his female parent. Deferral is still the hardest clip for Radon. He tells everyone that he has tonss of friends, but his female parent says that if you watch what goes on in the tiffin room or on the resort area ; it is difficult to calculate out who they are. Some childs avoid him, but most would give him a opportunity if he was nt so autocratic. The resort area supervisor attempts to acquire him involved in a association football game every twenty-four hours. He is nt bad at it, but he will non go through the ball, so no 1 truly wants him on his squad. After school is the clip that do his ma earnestly see foster attention. The place work conflict is atrocious. He refuses to make work for an hr, so complains, interrupt pencils, and annoy her. This drags 30 proceedingss of work out to two hours. So, now she hires a coach. He does nt seek all of this on the coach, at least so far. With no place work, he is easier to take. But he still wants to make something with her every minute. Each twenty-four hours he asks her to assist him with a theoretical account or play a game at approximately 4:30. Each twenty-four hours she tells him she can non right now as she is doing supper. Each twenty-four hours he screams out that she does nt of all time make anything with him, slams the door, and goes in the other room and normally turns the Television on really loud. She comes up, tells him to turn it down three times. He does nt and is sent to his room. After supper Radon s pa takes over and they play some games together and normally it goes all right for about an hr. Then it normally ended in shouting. He is so sent to bed and the twenty-four hours starts all over. Since I talked to Radon s female parent about him he has had a really hard clip at school. He is now being home tutored by the after school coach that he had before. The school has found him to be a menace to the staff and other kids. The incidents that lead to this were that he destroyed the principal s office, threated to kill two staff members, and three kids. The ma does non desire him set into a school for kids with behavioural upsets as she feels it will merely do him worse. Radon is now seeing three different people to assist with his upset. One is a societal worker, one is a head-shrinker and the other is an anger direction specializer. The school continues to work with her and if all goes good he will be transitioned back into the school following twelvemonth. She still has jobs with him at place. Causes There are many different theories that try to explicate Oppositional Defiant Disorder. There is the psychodynamic theory that interprets the aggressive and noncompliant behaviour as an indicant of a deeply-seated feeling of deficiency of love from the parents, the inability to swear and an absence of understanding. The behavioural theory suggests that Oppositional Defiant Disorder is caused by a dysfunctional household life, deficiency of parenting and the perennial giving into demands that are reinforced when bad behaviour occurs. The biological theory suggests that these behavioural jobs in kids could be caused by damages to certain countries of the encephalon. There is besides a nexus between the sum of certain chemicals in the encephalon and Oppositional Defiant Disorder. The biological theory suggests that if these chemicals are out of balance, the encephalon is so non working decently. Then the messages sent may non do it through the encephalon right, taking to symptoms of Oppo sitional Defiant Disorder. Last, cognitive theories province that the kid feels ill will in their lives and in bend respond to other with their ain ill will. Treatments The first measure is to measure the danger the kids pose to themselves or others and measure the impact that the environment may be holding on their continued development. It is of import to besides measure the ability of the kid parents to adequately care for them. In some instances, crisis attention or residential intervention may necessitate to see. Treatment for kids and striplings should include multiple avenues. Individual therapy, parent intercession, school intercession, and community based intercessions should all be considered. While there are several interventions available to assist they have non developed a medicine to handle this upset. There are medicines research workers say will assist with the symptoms but no decently executed survey has been completed. A intervention that is available nevertheless, would be Psychotherapy. This is a type of reding that is aimed at assisting the kids develop more effectual header and problem-solving accomplishments. There is besides household therapy, which may be used to assist better household interactions and communicating among household members, every bit good as parent direction preparation. This teaches parents ways to positively change their kid s behaviour. Last, there are behavior direction programs. These are an understanding between parents and kids that give wagess for positive behaviours and effects for negative behaviours. The interventions for Oppositional Defiant Disorder are normally a long-run committedness. It may take a twelvemonth or more of intervention to see noticeable betterment. It is of import for households to go on with intervention even if they see no immediate betterment. If Oppositional Defiant Disorder is non treated or if intervention is abandoned, the kid is more likely to develop behavior upset. The hazard of developing behavior upset is lower in kids who are merely mildly noncompliant. It is higher in kids who are more noncompliant and in kids who besides have Attention Deficit Hyperactivity Disorder. In grownups, behavior upset is called antisocial personality upset. Children who have untreated Oppositional Defiant Disorder are besides at hazard for developing passive-aggressive behaviours as grownups. Persons with passive-aggressive features tend to see themselves as victims and incrimination others for their jobs.

Soweto Student Uprising - 16 June, 1976

Soweto Student Uprising - 16 June, 1976 When high-school students in Soweto started protesting for better education on 16 June 1976, police responded with teargas and live bullets. It is commemorated today by a South African national holiday, Youth day, which honors all the young people who lost their lives in the struggle against Apartheid and Bantu Education.   In 1953 the Apartheid Government enacted The Bantu Education Act, which established a Black Education Department in the Department of Native Affairs. The role of this department was to compile a curriculum that suited the nature and requirements of the black people. The author of the legislation, Dr Hendrik Verwoerd (then Minister of Native Affairs, later Prime Minister), stated: Natives [blacks] must be taught from an early age that equality with Europeans [whites] is not for them. Black people were not to receive an education that would lead them to aspire to positions they wouldnt be allowed to hold in society. Instead they were to receive education designed to provide them with skills to serve their own people in the homelands or to work in laboring jobs under whites. Bantu Education did enable more children in Soweto to attend school than the old missionary system of education, but there was a severe lack of facilities. Nationally public to teacher ratios went up from 46:1 in 1955 to 58:1 in 1967. Overcrowded classrooms were used on a rota basis. There was also a lack of teachers, and many of those who did teach were underqualified. In 1961, only 10 per cent of black teachers held a matriculation certificate [last year of high school]. Because of the governments homelands policy, no new high schools were built in Soweto between 1962 and 1971 students were meant to move to their relevant homeland to attend the newly built schools there. Then in 1972 the government gave in to pressure from business to improve the Bantu Education system to meet businesss need for a better trained black workforce. 40 new schools were built in Soweto. Between 1972 and 1976 the number of pupils at secondary schools increased from 12,656 to 34,656. One in five Soweto children were attending secondary school. This increase in secondary school attendance had a significant effect on youth culture. Previously, many young people spent the time between leaving primary school and obtaining a job (if they were lucky) in gangs, which generally lacked any political consciousness. But now secondary school students were forming their own, much more politicized identity. Clashes between gangs and students only furthered the sense of student solidarity. In 1975 South Africa entered a period of economic depression. Schools were starved of funds the government spent R644 a year on a white childs education but only R42 on a black child. The Department of Bantu Education then announced it was removing the Standard 6 year from primary schools. Previously, in order to progress to Form 1 of secondary school, a pupil had to obtain a first or second-degree pass in Standard 6. Now the majority of pupils could proceed to secondary school. In 1976, 257,505 pupils enrolled in Form 1, but there was space for only 38,000. Many of the students therefore remained at primary school. Chaos ensued. The African Students Movement, founded in 1968 to voice student grievances, changed its name in January 1972 to the South African Students Movement (SASM) and pledged itself to building a national movement of high school students who would work with the Black Consciousness (BC) organization at black universities, the South African Students Organisation (SASO). This link with BC philosophies is significant as it gave students an appreciation for themselves as black people and helped politicize students. So when the Department of Education issued its decree that Afrikaans was to become a language of instruction at school, it was into an already volatile situation. Students objected to being taught in the language of the oppressor. Many teachers themselves could not speak Afrikaans, but were now required to teach their subjects in it.

Challenges to Nonprofits Essay Example | Topics and Well Written Essays - 1750 words

Challenges to Nonprofits - Essay Example That is why resource-allocation decisions present nonprofit executives with their best opportunity to focus resources on activities that will efficiently achieve their organizations' objectives. (Swords, n.d, online) Considering the significance of these choices, it is worrying that the financial systems in many nonprofit organizations aren't designed to support either short-term or long-term strategic decision making. Particularly, most financial systems do not add to organizational knowledge about the true, total costs of providing services, running programs and otherwise running the organization. Working without this information, nonprofit executives frequently have to make vital resource-related decisions on the basis of instinct, the skills and knowledge of the program staff, or the priorities of the organization's funders. (Swords, 2002, pp 113-114) Consequently, they run the risk of weakening their organizations' missions by failing to assign resources to the programs and services that have the highest impact. To make resource-related decisions in a way that enhances an organization's effectiveness and promotes its mission, nonprofit leaders need to have a clear picture of the full costs of operating their programs and services. ... ata can provide valuable input to decisions about how to assign resources among programs, whether to expand into a new setting, and what level of funding is required to sustain the organization's operations (Lang, 2000, pp 57-58). That Programs to Support The most essential resource-allocation decisions concern dividing funds among numerous programs in a single department. For example, one of Bridgespan's clients provided a range of counseling, adult-education, youth, and economic development services to its clients to help them become more self-reliant. An investigation of this organization's costs revealed that within the economic-development department, the employment-services program and the resume-services program were incurring the same cost. To put it other way, it was costing the organization the same amount of money to put a client in a job as it was to help her prepare a resume. Because having a job provides a client with better economic self-reliance than simply having a resume on hand, the organization decided to center its resources on the employment-services program instead of mounting the resume-services program as it had initially planned. Full and precise cost data can be uniformly enlightening when an organization's leaders are wrestling with the best way to divide resources among numerous sites. This was the situation facing a countrywide educational organization with seven regional affiliates. (Lang, 2000, pp 67-69) Because the organization's current accounting system stated that all its financial information on a line-item basis, area cost data had never been collected. When these data were collected and examined, the organization learned that the cost of training teachers differed significantly by locality. These findings encouraged a

Causes of Obesity in the USA Research Paper Example | Topics and Well Written Essays - 2000 words

Causes of Obesity in the USA - Research Paper Example Obesity is a health state typically caused by a mixture of unwarranted food energy ingestion, absence of physical activity, and genetic vulnerability. In certain situations, obesity is as a consequence of genes, endocrine turmoil, prescriptions or psychiatric ailments. There is also evidence to sustain this supposition that certain obese individuals ingest little. Nonetheless, they gain weight as a consequence of slow metabolism. Typically obese individuals have significant energy expenditure than skinny individuals as a result of energy needed to sustain a heightened body mass. Obesity also defines the condition of having at least over thirty percent of the idyllic body mass for an individual’s height. It describes the condition of having disproportionate amount of fat relative to one’s lean muscle in the body (Haslam and James 31). Obesity is a principal, avoidable cause of demise globally, with heightened frequency in adults and kids.

America hosts the most obese individuals in the globe. This implies that two thirds of the American populace is overweight. There are varied components of contemporary life that have added to th e causes of this health condition and its detrimental impacts to people’s lives. However, there are interior mechanisms that have a significant impact including an individual’s appetite, metabolism as well as satiety from foodstuff.

Causes of Obesity The foodstuffs individuals consume daily contribute to their well-being. These foods supplies with the crucial nutrients they require for vigorous bodies and the calories essential for energy. However, overconsumption of calories results in obesity.

With regard to genes, obesity is an ailment that runs in family units. This is usually as a consequence of genes as well as mutual diet and lifestyle behavior. Another significant cause of obesity is emotions. Certain individuals overeat as a

Problem gambling Essay Example for Free

Problem gambling Essay She took one last look out the window as they drove away, the tears streaming down her face. At the age of four, her world had fallen apart. Karina’s life started out as a perfect middle-class family, and soon turned into a broken mess. They had everything, a perfect house in a really nice part of the city, a nice car; everything was wonderful. As Karina got older, she began to notice things weren’t perfect. Her dad was never there. He was always out gambling in one way or another. â€Å"As time progressed we lost the car, and other possessions due to my dad’s gambling problem. It’s not only about gambling and the money. When people gamble, they do other stupid things, he had an affair. My parents decided to get a divorce. My dad didn’t argue, in fact he said that for the safety of our family it would probably be better because a lot of people were angry at him for what he owed them. It was all because of gambling and snowballed into a mess that could have been really dangerous for my mom and me had we stayed around. I’m sad that my life played out in that way at such a young age, and it’s very unfortunate. I know that if he wouldn’t have had gambling around none of those things would have taken place and we would probably still be the family that we were, but unfortunately that’s not how it played out. † Although many people think that legalizing gambling will have a great effect on the economy, I think the negative effects are much more evident. People’s views on subjects often have to do with their ethics. Ethics, as defined by Seiler and Beall, are an individual’s system of moral principles. My ethics lead me to believe that gambling is wrong because I was raised to believe that my family is more important than economic wealth. As it is evident in the story above, gambling can have a major negative effect on someone’s life, and so it is too much of a risk to legalize this dangerous game. Three main reasons that gambling should be kept illegal are that gambling creates tension among the family members, gambling increases crime in the society, and the addiction to gambling is too great for many to overcome. The first reason that gambling should be kept illegal is that gambling creates tension among the family members as the money that should be used for the family is being spent on gambling. Even though gambling might, in some cases, bring money into the state and local economies, there are side effects to having a casino down the street. Forshey (1998) states, â€Å"The gambling jobs, taxes, and recreational values provided by the industry cannot compensate for the social pain-in the form of bankruptcies, white-collar crime, divorce, a compromised political process, an increase in alcoholism-it inflicts. † The drain of a working person’s money that wager’s his or her paycheck and loses is not compensated with the amount of jobs a casino brings to a community. Gambling is a greedy industry that produces nothing more than empty hopes, empty dreams and empty wallets. Anderson states, â€Å"Proponents argue that state lotteries are an effective way to raise taxes painlessly. But the evidence shows that legalized gambling often hurts those who are poor and disadvantaged. † Without casino gambling, many local citizens would spend their money on groceries or clothes, instead of reducing their savings on gambling. As William Thompson states in his article â€Å"Gambling: A Controlling Substance,† It [gambling] is a pleasure, like other entertainment, but in that regard, it is an expensive pleasure. † Thompson then continues with this thought: â€Å"Politicians must recognize that the benefits of gambling are bounded by market structures. Gambling money does not grow on trees. It comes out of the pockets or real people, who otherwise would have spent it on something else. † All of this evidence shoes that gambling should be kept illegal because it creates tension among the family members as the money that should be used for the family is being spent on gambling. A second reason that gambling should be kept illegal is that gambling increases the amount of crime within a society. Gambling often becomes associated with crime, a relationship that seems quite understandable. Not only does gambling continue to be illegal in some forms which makes it a crime to participate in, but also the second half of the issue occurs when gambling increases the amount of street crime in a surrounding area. Crime rates have been significantly higher in places that allow gambling. Kindt states, â€Å"Atlantic City showed a jump in crime when gambling was legalized. The city went from 50th in the nation in per capita crime to first. Problem gamblers may also become more likely to have financial troubles and use illegal activities as a way to pay off their debts and keep up their unhealthy habit. † This graphic shows a report done by the U. S. Department of Justice studied people that were arrested in Las Vegas and Des Moines, Iowa. The results show many connections between gambling and crime. â€Å"More than 30 percent of pathological gamblers who had been arrested in Las Vegas and Des Moines reported having committed a robbery within the past year, nearly double the percentage for low-risk gamblers. Nearly one-third admitted that they had committed the robbery to pay for gambling or to pay gambling debts. In addition, about 13 perfect said they had assaulted someone to get money. † As is evident, gambling should be kept illegal because it increases the amount of crime within a society. We will now look at the last reason why gambling should be kept illegal. Finally, a third reason that gambling should be kept illegal is that the addiction to gambling is too great for many to overcome, resulting in psychological problems for the gambler. Some people argue that if a person wants to gamble badly enough they will do it. They say that one will be able to control his or herself and only gamble when it’s appropriate, but gambling is an addiction that some people can’t escape. The addiction is a nationwide problem, and as much a part of gambling as the dice. As an article in the Omaha World Herald states, â€Å"Problem gambling is the urge to gamble despite harmful negative consequence or the desire to stop, and pathological gambling involves wagering to such excess that it has a severe negative effect on the gambler’s life. † Getting hooked on gambling comes mainly from the action and thrill, an experience chemically the same as those with inhaled substances. They fall under the spell of action. Action is an aroused, joyous state involving excitement, tension, and anticipation of the outcome of a gambling event. It is the thrill of living on the edge. Gambling has little to do with money and everything to do with the feelings of a gambler. William Thompson states, â€Å"People will lie to themselves, also in calculating the money because they don’t want to tell themselves that they were foolish about gambling. † Problem gamblers describe gambling as â€Å"highs† similar to that experienced from many drug substances. Some experience these sensations when just thinking about gambling. How is a person supposed to avoid gambling if he or she is constantly being surrounded with opportunities to place bets and be involved in the â€Å"action†? As Frey suggests casinos increase the number of problem gamblers, and make it that much more difficult to stop for those already addicted. In order to stop the number of pathological gamblers from increasing, the amount of gambling in the United States must decrease as a whole. Pathological gamblers were twice as likely to describe their general health as fair to poor over the past two years and were more likely to acknowledge mental or emotional problems. Rates of alcohol and drug dependence, job loss, and bankruptcy were also significantly higher for pathological gamblers relative to non-gamblers. According to Weinstock and Meyers, â€Å" Almost 20 percent of the people diagnosed as pathological gamblers file for bankruptcy compared to the less than 5 percent of those in the general population. † Percentage of Population with Gambling Problems In order to stop the number of pathological gamblers from increasing, the amount of gambling in the United States must decrease as a whole. As is evident in this bar graph the amount of people with gambling disorders has greatly increased. According to Weinstock and Meyers, â€Å"Recent studies have found that approximately 2 percent of Americans have had severe levels of disordered gambling at some point in their lifetime. Alarmingly, the rate in the Mid-South is even higher. Studies with Mississippi and Louisiana reveal that about 5 percent of the residents in Mississippi have a gambling problem, while in New Orleans, Louisiana 8 percent of the population reported significant problems because of their gambling. † Gambling should be kept illegal because the addiction to gambling is too great for many, even adolescents to overcome. According to Welte, Barnes, Tidwell, and Hoffman, â€Å"Over 2% of U. S. adolescents have experienced problem gambling (i. e. , sub-clinical pathological gambling) in the past year. Females have a . 1% problem gambling rate, and males a 4. 2% problem gambling rate within the past year. † If we don’t put a stop to this now the future of pathological gambling will continue. Regrettably, these pathological gamblers will most likely have to deal with many adverse life events because of their addiction. Many problem gamblers are under so much stress, they commit domestic violence or suicide. There are other, less dangerous ways to find entertainment. So many people suffer every day from their addiction to gambling. The United States should put a stop by banning the gambling industry, and therefore eliminating the harmful side effects of legalized gambling. All of this evidence shows that gambling should be kept illegal because the addiction to gambling is far too great for some people to overcome, resulting in psychological problems for the gambler. The negative effects of gambling out-weigh the positive. The tension created among family members, increased crime in society, and the addiction resulting in psychological problems are just too great of a risk for the people of our society to undergo. So the next time you walk into a casino, remember Karina’s story and how the gambling may affect your life, because even if you’re willing to take the chance, odds are the negative effects of gambling will leave you unlucky in life. It is important for all of you to take note of the consequences and refrain from gambling. Staying away from the dangers of gambling, and setting an example to others is extremely important. No matter what type of personality you have, you can be an influence to others and help stop the spread of gambling all over the nation. I want to challenge you that if you know someone that gambles or you yourself gamble share what you know about gambling and try to put a stop to the habit! References: * Anderson, K. Gambling.

The league of extraordinary gentlemen movie review :: essays research papers

"The League of Extraordinary Gentlemen" Despite Sean Connery and some impressive 19th century gloom, this big-screen translation of Alan Moore's culty comic-book series falls to earth with an incoherent splat. - - - - - - - - - - - - By Charles Taylor July 11, 2003 | In the opening scene of "The League of Extraordinary Gentlemen," a tank plows through the elegant Victorian interiors of the Bank of England. In short order, we see the destruction of an inn in Kenya, an enormous book-lined London sitting room, and the center of Venice, with the Basilica San Marco among the buildings reduced to rubble. This a destructo-thon for those with a taste for Old World elegance. There's no reason why "The League of Extraordinary Gentleman" has to be as bad as it is, considering the inspired pop premise of its source, Alan Moore and Kevin O'Neill's graphic novel. The two installments that have appeared in book form so far are a sort of cold daydream of popular literature. Set at the end of the 19th century, the comics tell the story of a group of heroes assembled by British intelligence to fight various threats to the empire. The ingenious element is that all of these adventurers are characters from popular fiction of the era. There's the aged Allen Quatermain (the adventurer from H. Rider Haggard's "King Solomon's Mines"); Mina Harker, nà ©e Murray (from "Dracula"); H.G. Wells' the Invisible Man; Dr. Henry Jekyll and his alter ego Edward Hyde (who takes the form of a grotesque behemoth); and Captain Nemo (from Jules Verne's "Twenty Thousand Leagues Under the Sea"). Their contact with the British government is an ancestor of James Bond and, as in the Bond books and movies, the head of British intelligence is M, and his initial is a hint at his own fictional identity. Moore and O'Neill use these characters to play a sophisticated version of the fantasies kids indulge in about whether Superman could defeat Spider-Man. The graphic novels are written and drawn in a style that mingles the formality of Victorian literature with contemporary raunch and bloodthirstiness. When Hyde goes on a rampage we get to see him ripping bad guys quite literally in two, or chomping on their limbs. The Invisible Man takes advantage of the sexual liberties open to a man who can't be seen.

Experiment to Measure the Heart Rate and Ventilation Rate Before, During and After Moderate Exercise Essay

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise. Experiment: 1. To start with the experiment we measured the persons resting heart rate and respiratory rate where there was no strain on the muscles. We continued to check both pulse and respiratory rates at 30 second intervals during the course of exercise. 2. We decided to make the length of each consecutive exercise 30 seconds long. Between each session we allowed the student’s pulse and respiratory rate return to their resting rates, otherwise the results would not be fair if both rates were higher at the start of the exercise. 3.  Throughout each exercise the student made sure that equal paces were maintained so that it would not affect the heart or respiratory rate in a different way. Immediately after exercise the subject sat down in a chair so that both the heart and respiratory rates could be taken. The pulse rate was measured first for 15 seconds, if we had taken the pulse rate for 1 minute the pulse rate would have slowed down. As soon as the pulse rate was taken we then took the respiratory rate for 15 seconds. We then waited for both rates to return to their normal resting rates before starting the next exercise. Fair Testing: Our experiment was about how the heart and respiratory rates are affected by exercise. Unless we use a stethoscope we cannot measure both rates directly. We measured the pulse rate on the carotid artery. This will keep the experiment fair because each heart beat set up a ripple of pressure which passes along the arteries. The ripple can be felt as a pulse as the artery’s muscular wall expands and relaxes. Measuring the pulse rate is measuring the subject’s hearts beats except there is minimal lapse between the beat and the pulse. The diastole and systole produce a very distinctive two tone sound which is very easily felt. So to make sure we do not count twice we will always count the first pulse of the two. (Boyle and Senior Pgs. 160 – 161) Tiffin (Northumberland College Notes Jan’12) Sources of Error: The sources of error in this experiment that we would have to include are: * Subject being fit / unfit †¢ Healthy / Unhealthy * Smoker / Non-smoker †¢ On regular medication * Drinker / Non-drinker †¢ Suffer from any illnesses * No ECG Monitor †¢ Male / Female We have to make sure that we keep the same person throughout. This is because every person has a different diet, fitness level, weight, stature or is a different gender. All these factors affect a person’s heart or respiratory rate. If the person was changed during the experiment the results would not be reliable or fair. The subject’s resting heart and respiratory rates would be different and their body’s reaction to exercise would also be different. The pace of the subject will affect their heart and respiratory rates. They may start off at a quick pace, but go slower when they begin to tire. The subject must rest between each exercise so that all the lactic acid and CO? can be carried away. The tiredness of the student will affect the pace at which the subject performs their exercise. This is why it is crucial for fair results throughout the exercise. It is also necessary to allow the subject to recover before carrying on with their exercise. We must measure the subject’s pulse and respiratory rates in the same position as we did their resting rates. If we do not, we would not get accurate results. If we were to take the subject’s pulse rate standing up the heart rate would rise because the muscles are working to keep the subject upright. The heart rate would have to work harder in order to keep their muscles working. We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use. I have placed the results from our experiment in form of a table and will use the average results to form a graph. I have also prepared a graph to show the results throughout the exercise. As the results show the highest increase in the pulse rate is in exercise 2 where the pulse rises by 44 BPM and the respiratory rate by 8 RR. Thereafter it continues to rise by 40 BPM and 8 RR. We did however experience a higher respiratory rate in the second lot of results in exercise 4 where the respiratory rate did rise by 12 RR. During exercise, the subject’s heart rate, systolic blood pressure, and their cardiac output (the amount of blood pumped per heart beat) all increase to maintain a state of balance, known as homeostasis. Homeostasis is a self-regulating process by which the human body maintains internal stability under fluctuating environmental conditions. Blood flow to the subject’s heart, their muscles, and their skin increase. Sweat glands secrete a salty solution that evaporates from the skin, taking heat with it. Their body’s metabolism becomes more active, producing CO? and H+ in the muscles and consequently lowers PH. The subject breathes faster and deeper to supply the oxygen required by this increased metabolism. With strenuous exercise, their body’s metabolism exceeds the oxygen supply and begins to use alternate biochemical processes that do not require oxygen. These processes generate lactic acid, which enters their blood stream. The subject’s cardiovascular system, their breathing system and their muscles work in conjunction with each other in order to perform their tasks more efficiently. A vital process of exercise is respiration (the production of energy). Principally, respiration is the breakdown of oxygen and glucose into carbon dioxide, water and ATP. Aerobic respiration requires oxygen and has the ability to break down both fatty acids and glucose. Anaerobic respiration takes place when there is a lack of oxygen, a lactate is formed and fatty acids cannot be broken down. (Boyle and Senior Pgs. 62, Pg. 215 and Pg. 222) Tiffin (Northumberland College Notes Feb’12) Glucose + Oxygen Carbon Dioxide + Water – C6H12O6 + 6O? —–>6CO? +6H? O+Energy Oxygen is taken into the subject’s lungs and then diffused into their bloodstream. Cells need oxygen to respire so more oxygen needs to be transported to muscle cells. This then causes the subject to breathe more deeply. Thei r intercostal muscles (muscles in between the ribs) contract up and out, moving the subject’s ribs and diaphragm up and out (a sheet of muscle at the bottom of the thorax, chest cavity). This increases the subject’s space available in their lungs for air to fill. More air in the lungs means there is more oxygen, so that more oxygen can be diffused into the bloodstream. The number of the subject’s breaths increases too, to maintain a high concentration gradient. Heart rate also needs to increase to keep their blood flowing through the lungs. The subject’s heart and respiratory rates rise because during exercise, their cell respiration in the muscles increase, so the level of carbon dioxide in their blood rises. Carbon dioxide is slightly acid, the brain detects the rising acidity in the subject’s blood, their brain then sends a signal through the nervous system to their lungs to breathe faster and deeper. Blood flows from areas of high pressure to areas of low pressure. The area of high pressure is the pressure created by the contraction of the subject’s ventricles, which forces blood out of their heart into the aorta. Resistance is caused by friction between the blood and the vessel walls. Gaseous exchange in the subject’s lungs increases allowing more oxygen into their circulatory system and removing more carbon dioxide. The subject’s brain then sends a signal to the sinoatrial node (SAN) to make the heart beat faster. Heart rate is controlled by the SAN. The subject’s rate goes up or down when the SAN receives information via their two automatic nerves. (Boyle and Senior Pgs. 160-162) Tiffin (Northumberland College Notes Jan-Feb 2012) †¢ Their sympathetic or accelerator nerve which speeds up their heart rate. The synapses at the end of this nerve secrete noradrenaline. †¢ Their parasympathetic or decelerator nerve, a branch of their vagus nerve, slows down their heart rate. (Boyle and Senior Pg. 162) A negative feedback system controls the subject’s level of carbon dioxide. During exercise, their blood level of carbon dioxide starts to rise. This is detected by chemoreceptors situated in three places: the carotid artery, the aorta and the medulla. Nerve impulses travel from these receptors to the subject’s cardiovascular centre. In response, their cardiovascular centre sends impulses down the sympathetic nerve to increase the subject’s heart rate. Their heart rate returns to normal after the cardiovascular centre sends impulses down the parasympathetic nerve once carbon dioxide levels have dropped. Boyle and Senior Pg. 162) Tiffin (Northumberland College Notes Feb’12) At rest During Exercise These images illustrate the alveoli and a red blood cell during rest and activity. This is the site where the red blood cells exchange carbon dioxide molecules for oxygen molecules to transport throughout the body. Notice the increase of both molecules as activity increases. (Zygote Media Group, Inc. ) The heart’s natural pacemaker – the SA node – sends out regular electrical impulses from the top chamber (the atrium) causing it to contract and pump blood into the bottom chamber (the ventricle). The electrical impulse is then conducted to the ventricles through a form of ‘junction box’ called the AV node. The impulse spreads into the ventricles, causing the muscle to contract and to pump out the blood. The blood from the right ventricle goes to the lungs, and the blood from the left ventricle goes to the body. (SADS Sudden Arrhythmic Death Syndrome) Conclusion: I have concluded, with the evidence provided in the graphs and table, in which the pulse and ventilation rates do increase during exercise. Overall, the results confirm the initial prediction that the heart and ventilation rates increase during exercise and return to normal level shortly after exercise has been completed. Heart and ventilation rates increased during the high intensity exercise to feed the body’s need for more oxygen and energy have been decreasing gradually immediately after exercise has finished as the muscles did not need more energy than usually. It is important to take into account each individual’s personal health, fitness and lifestyle when considering the effects of exercise. Generally, the fitter the individual, more quickly the resting rate is achieved.

Baldwin Notes of a Native Son Analysis Essay

â€Å"Notes of a Native Son† is a first person narrative about James Baldwin who lived with his family in Harlem during a difficult time for the equal rights movement in America. Racism through Baldwin’s experience shows its potential to feed off of itself in a vicious cycle, with one person’s hate leading to someone else’s. He has first hand experience with this through his father, a man who, while considered free, felt the pressures of racism throughout his life. The hate Baldwin’s father had towards white people was a reflection of the current state of equal rights in the country. Baldwin finally understands his father’s feelings when he moves to New Jersey and sees racism for himself. He eventually comes full circle to realize the true problem with racism, but he is too late to reconcile with his father. The story begins with a nineteen-year-old James Baldwin at his father’s funeral. Looking back on the time he spent with his fathe r, Baldwin realizes that he very rarely spoke to his father and had almost no relationship with him. Baldwin credits this partially to the fact that both him and his father were stubborn and prideful, but also maintains his father â€Å"could be chilling in the pulpit and indescribably cruel in his personal life and he was certainly the most bitter man I have ever met; yet it must be said that there was something else to him, buried in him, which lent him his tremendous power and, even, a rather crushing charm† (Baldwin 588). This bitterness is a natural reaction to the racial tensions during Baldwin’s father’s life. Baldwin remembers his father as an angry man who distrusted all white people because he was among the first generations of free men and, during his time, racism was very prevalent in the United States. His father had been ill a long time and ended up dying of tuberculosis. However, he was also sick with paranoia; this â€Å"disease of his mind allowed the disease of his body to destroy him† (Baldwin 590). Baldwin actually comments that throughout his whole life, he never remembers a time where any of his brothers or sisters was actually happy to see their father. His father always warned his children not to trust white people, and often warned that some of them may be nice from time to time, but that none of them were to be trusted. However, as an innocent child, Baldwin wanted to believe that white people were not all inherently evil like his father said. This hope was e mbodied by one of Baldwin’s teachers who helped him and his family for a time when ’s father got laid off from his job. However as Baldwin grows  older, he begins to see why his father was so bitter toward white people. He moves to New Jersey where he realizes, to his surprise, that even in northern states, to be a negro meant that â€Å"one was never looked at but was simply at the mercy of the reflexes of the color of one’s skin caused in other people†(592). While living in New Jersey, he feels everyone trying to â€Å"eject† him (592); he is fired from his job and re-hired three times in one year. On his last night in New Jersey, he goes to Trenton with a friend for drinks and a movie. When they went to the â€Å"American Diner† they were refused service because the diner â€Å"didn’t serve negroes† (593). Soon after, he was refused service again and nearly assaulted a waitress. This represents the moment where he truly understands his father’s anger. He now feels upset and has a wish too reconcile with his father, but obviously no longer has the opportunity to do so. Baldwin reminisces on a time when he went to see his father during the illness, and the last time before he died. He had put off seeing him for so long because he did not want to see his father in the state he was in. He had hated his father for the man he once was but seeing who he had become only made Baldwin feel sorry for him. He realizes that he shouldn’t have hated his father for how he felt and wishes he were there to talk to him. Baldwin understands that hatred not only hurts the people being hated, it also destroys the man who hates, and real change will only happen if we can separate ourselves from this hate on both sides. Baldwin sees many different sides of racism throughout his life; from a child who disagrees with his father’s hatred of white people, to an adult that also caught the â€Å"illness† that his father had. These experiences eventually bring him to the realization of the underlying problem of racism. Baldwin sees the sickness that the country suffers from does not stem solely from one side spreading hate, but from both sides equally making it that way. Although whites spread racism and hate, blacks responded in a similar fashion, which only made the situation worse. When one group hates another, that hatred not only hurts the victims, but also destroys those who hate. â€Å"Hatred, which could destroy so much, never failed to destroy the man who hated and this was an immutable law† (603). The only hope to abolish racism and the hatred that comes along with it is for both sides to try and understand each other to overcome the hate. I agree with Baldwin when he  says , â€Å"it now had been laid to my charge to keep my own heart free of hatred and despair† (604). It is up to us to separate ourselves from the hate so all can understand and improve the lives of others instead of destroying them.

The heat given out by different types of primary alcohols Essays

The heat given out by different types of primary alcohols Essays The heat given out by different types of primary alcohols Essay The heat given out by different types of primary alcohols Essay In my investigation I will measure the heat given out by different types of primary alcohols when combusting with oxygen and compare the difference in the energy out put per mole of different alcohols.HypothesesBefore we can have a look at the heat content of the different alcohols, we must be able to understand the process of combustion, the changes of the energy within the system while combusting with oxygen and how to determine the difference of the energy given out per unit.First it is crucial to know that it is the external energy that we are measuring of the system, because as the Second Law of thermodynamics states that heat cannot be completely converted into work without some part of the system undergoing change, a equation is applied to the law illustrates that H (total heat content) = G (free energy) + TS (temperatureà ¯Ã‚ ¿Ã‚ ½entropy, TS is the unfree energy which is associated with the degree of disorder of the system), and H can only be equal t o G when TS=0 which only takes place at the temperature of absolute zero.We therefore cannot measure the total change in enthalpy (total heat content) since the 3rd law of thermodynamics states that absolute zero cannot be reached; the entropy which measures the degree of disorder also increases spontaneously that the particles of the system become disorderer or more random. What this investigation measures is the spontaneous change in the free energy which is converted into heat as stated in the second law of thermodynamics.Then it is necessary to know that the reaction is exothermic that is heat or in another word kinetic energy and light energy, which is the emission given out when the exited electron return to a lower energy levels, are given out to the surroundings causing the surroundings to gain more kinetic energy and rise in temperature. We can measure the different values of the bond energy of the reactants and the variation between the two values, if the value of variatio n is positive i.e. when energy is gained the reaction is endothermic, but if the value appears to be negative, then the reaction is exothermic. It is possible to calculate the average bond energy measured in kilo joules per mole (DH/KJ mol-1) and determine the variation. Knowing that C-H=413; C-O=336; C==O=805; H-O=464; O==O=498.3 and the following equation it is possible to calculate ?E.2CH3 (OH) +3O2= 2CO2 +4H2O(413à ¯Ã‚ ¿Ã‚ ½3+336+464)à ¯Ã‚ ¿Ã‚ ½2+498.3à ¯Ã‚ ¿Ã‚ ½3-805à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½2-464à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½4=-1359.1 KJ, thus the reaction is exothermic. And since the reactions of other alcohols are similar then we can say that the other alcohol combustions are exothermic.Another fact that we must know is that the end products of any combustion reaction are carbon dioxide and water, but before the new molecules can be formed, a certain energy level is needed to give sufficient energy for the collision by what means that if the energy is not sufficient or incorrec tly orientated the reactants will not form, sufficient energy that is needed to be reached is the activation energy of the system to form the activated complex that the atoms are separated.From the state of transition the particles in the molecules now attract to particles of opposite charge, and the orbital become over lapped that the some electrons of the orbital in the outer shell are influenced by both nuclei and therefore forms the molecular orbital (M.O.), and the electrons occupies the orbital whose energy is the lowest available to it. The filling of electrons to the M.O. i.e. the orbital in the sub-shells of the shells are filled up with electrons leads to the drop in energy level of the electrons which can also be called bond energy since it is the energy needed for the transition of energy level of the electrons. This can also be regarded as spontaneous change of the system that it tend to a minimum in potential energy, because the first law of thermodynamics states that energy can neither be created nor destroyed but is simply transferred from one form or system another, the decrease in the energy level of the electrons must mean that energy is transferred to the surroundings.From the information above I can now decide that the energy released per mole is determine by the decrease in energy level of the electrons of the valence shell spontaneously and the number of M.O. When there are more carbon atoms with in an alcohol, there will be more hydrogen atoms within the molecule as well, so that when the new molecules are formed there will be more M.O. of the similar sort formed and more energy will be released, according to the theories I have explained above.If we know the value of the reduction in the energy level when the M.O. are formed (the bond energy), the symbol equation of the reactions and the relative atomic mass (R.A.M.), then it is possible to calculate the energy given out per mole. I will work out the energy released per mole and I woul d expect the result of my experiment follow a similar pattern of increase of the set of values below. As we already knew, C-H=413; C-O=336; C==O=805; H-O=464; O==O=498.3; C-C=347Methanol: 2CH3OH+3O2= 2CO2 +4H2O(413à ¯Ã‚ ¿Ã‚ ½3+336+464)à ¯Ã‚ ¿Ã‚ ½2+498.3à ¯Ã‚ ¿Ã‚ ½3-805à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½2-464à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½4=-1359.1 kJ; 1359.1?2=679.55kJ mol-1Ethanol: C2H5OH+3O2=2CO2+3H2O347+413à ¯Ã‚ ¿Ã‚ ½5+336+464+3à ¯Ã‚ ¿Ã‚ ½498.3-(805à ¯Ã‚ ¿Ã‚ ½2)à ¯Ã‚ ¿Ã‚ ½2-(464à ¯Ã‚ ¿Ã‚ ½2)à ¯Ã‚ ¿Ã‚ ½= -1297.1kJ1297.1à ¯Ã‚ ¿Ã‚ ½1=1297.1 kJ mol-1Propan-1-ol: 2C3H7OH+9O2=6CO2+8H2O(347à ¯Ã‚ ¿Ã‚ ½2+413à ¯Ã‚ ¿Ã‚ ½7+336+464)à ¯Ã‚ ¿Ã‚ ½2+498.3à ¯Ã‚ ¿Ã‚ ½9-805à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½6-464à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½8= -3829.3kJ3829.3à ¯Ã‚ ¿Ã‚ ½2=1914.65 kJ mol-1Butan-1-ol: C4H9OH+6O2=4CO2+5H2O347à ¯Ã‚ ¿Ã‚ ½3+413à ¯Ã‚ ¿Ã‚ ½9+336+464+498.3à ¯Ã‚ ¿Ã‚ ½6-805à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½4-464à ¯Ã‚ ¿Ã‚ ½2à ¯Ã‚ ¿Ã‚ ½5= -2532.2kJ2532.2à ¯Ã‚ ¿Ã‚ ½1=2532.2kJ mol-1From these set of results it is pos sible to predict that as the number of carbon atoms increases within an alcohol molecule, the energy out put per mole will also increase.Safety* Alcohols are highly flammable so that the spirit burners must be dealt with caution, any alcohol spillages on any surfaces must be cleaned immediately in case of fire.* Alcohols can cause blindness and death when took into the body, one must seek medical attention when took in.* Avoid touching the apparatus directly after experiments, when which will be heated up.* The flame must be kept distance away from other unnecessary apparatus.* Safety goggles and lab coats must be worn, and first aid kits and other first aid equipments must be ready in case of emergencies. (See photo 4)Apparatus* Spirit burner containing methanol, ethanol, propanol-1-ol and butanol-1-ol* Stand, boss and clamp* Thermometer* Digital balance accurate to 10-2 digits* Ruler* 2à ¯Ã‚ ¿Ã‚ ½100ml2 measuring cylinder* Safety goggles, lab coats* Stop clock* Tin can* Heat proo f mat(See photo 1)MethodIn order to carry out this investigation, two measurements must be taken; they are the loss in the weight of the alcohols, and the temperature change of the water. Subsequently before we can start the experiment we must measure the weight of the spirit burner, and record the reading. Then the stand boss and the clamp should be set up to fix the tin in place. The reason why I have chosen the tin to be the calorimeter is because it is a good conductor to heat thus it has a relatively low heat capacity, and more kinetic energy can be passed to the water molecules efficiently to make accurate my results.The spirit burner should be positioned directly beneath the tin and a heat proof mat is needed to be placed under the spirit burner. The distance between the peak of the wick and the bottom of the tin must be kept constant in order to carry out a fair comparison. A draught shield is needed to be placed around the spirit burner and the tin to prevent the unnecessar y heat loss that could vary the result of the experiment. (See photo 2) After the apparatus have been set up as described above, then we must measure 200ml of water of 2à ¯Ã‚ ¿Ã‚ ½100ml measuring cylinder and add which to the tin, and then place the thermometer to the water and wait until the reading is stable. It important to keep the volume of water constant since the energy required to raise 1oc is associated with the mass.This stable reading can give the actual temperature before the experiment and this also tells me the temperature of the tin since the one have higher energy tends to give out energy spontaneously and equilibrium can be reached between the two. Knowing the heat capacity of the tin it is possible to calculate how much energy the calorimeter receives and this can give me a more accurate value of the heat generated by the alcohol. Since equilibrium can be reached by energy transfer from a hotter system to a colder, I can therefor say that the temperature of the ti n can is almost the same as the water. Now that knowing the heat capacity of the calorimeter system which is 0.277 kJ m3 oc and the weight of the tin can is 40.937g, then the energy that had been absorbed in each of the experiments can be calculated.After the preparations it is time to start the experiment by lighting the spirit burner thought the hole in the draught shield using a stick. The experiment will be carried out for approximately 180 seconds, the time is set upon the preliminary work I have done that this could prevent the maximum evaporation of water while efficient energy can be gained by the water to show a positive result. The reading from the thermometer must be taking quite exactly the same time when the flame extinguishes so that an accurate value can result that further out put of energy that will not be taken into account can be avoided.The spirit burner must also be weighed immediately to give a result as accurate as possible, since the weight can be reduced fro m other ways such as evaporation. The experiment of each alcohol will be carried out 3 times to give an accurate result and the same experiment will be repeated for each alcohol. Between each experiment it is necessary to clean off the carbon as the result of incomplete combustion produced at the bottom of the tin, because it can act as an insulator which will have effects on the accuracy of the results. One other of the natures of combustions is that the flame is not stable and within a flame the distribution of heat is not equal.Consequently it must me made sure that the sizes of the flames are the same since the distance between the wick and the tin can is already at constant. A difference between the cotton part, which is the interior of the wick, and the exterior material can cause a difference in the size of the flame, thus I have decided to cut the wick before each experiment to maintain the size of the flames. (See Photo 3) At this point it is vital to point out that the ran ge of alcohol used be limited within the primary alcohols, which all have similar molecular structures in terms of the arrangement, so that methanol, ethanol, propan-1-ol and butan-1-ol are used. I also felt that there is no significance in caring out the experiment further that pentan-1-ol and hexan-1-ol are necessary, since I can discover the pattern from the first four.Fair testIn the table below I will illustrate the thing that I will keep constant and that will vary to produce results of use.VariablesConstantsType of primary alcoholVolume of waterApproximately the same timeDistance between the top of spirit burner and the bottom of tinApproximately the same surface area of tin covered by the draught shieldWickThe same calorimeterResults:(See table 1, 2, 3 and graph 1, 2,3)Analysis:By looking a Graph 1, it is possible to see the correlation between the number of carbon atoms and the energy output per mole. The correlation had illustrated that both the expected values and observe d values are positive, how ever the expected values increase steadily with a high gradient than the values of the experiment. The outcome was expected and the cause had already been explained in the hypothesis. First by nature it is not possible to make 100% use from the energy given out by the reaction, because the energy given is mainly in the form of heat, the movement of particles that can be lost very easily.Evidence have also shown that the combustion is not complete because carbon, one of the activated complex in the process of the reaction had not been combined with oxygen forming carbon dioxide, thus less energy is produced by the reaction due to the incomplete combustion; the amount of carbon collected at the bottom of the tin can had increased as the alcohols containing more carbon was used, showing that more of the combustion/reaction was incomplete when the time for each spirit burner to combust was roughly 180 seconds.From graph 1 along, it is difficult to identify the anomalies due to its scale, thus the observed results had been put onto a new graph. (See graph 3) From the graph it is then possible to see that there is no anomalies in the experiment since the line of best fit goes through the error bars of the plotted points on the graph, the error bars represented the possible variation of data due to the inaccuracies experiment. But when looking at graph 2, the percentage of accuracy decreases as the number of carbon increases, butan-1-ol in particular had an anomalous value. If one of the values of the data in the percentage/accuracy graph is anomalous, then this value must also be at the wrong position in the energy output/carbon atoms graph, however there is not enough evident to investigate further.The characteristics of this calorimeter system only allows us to measure the heat transfer from one system to another, however heat was not the only product of the reaction that a relatively large part of the energy is in the forms of light, wh ich cannot be measured by the calorimeter system. However the difference in the gradient of the two lines of best fit had shown that they increase at different rates, i.e. there are errors in the last experiments which had made the rate of increase of the observed values differ from the expected.The percentage of accuracy of the results obtain from the experiment is shown on graph 2. From which it is clear that the results became less accurate as the chain of carbons got longer, in theory the molecule will increase its activation energy as the number of carbon atoms increases because each carbon atom have 4 half full sub-shells, since the electrons follow the Hund principle which states that when filling a sub-shell, there is less electron repulsion if each of each orbital is half-filled first before any single one is completely filled.In the M shell of carbon, 2s, 2px, 2py and 2pz orbital are half filled of that the 4 unpaired electrons can attract 4 other nuclei, thus the more car bon there is the half filled orbital there are. Again, as I had stated in my prediction that the energy level, the potential energy in particular of the electrons will drop, when an orbital is full, therefore more energy is required to provide sufficient energy i.e. bring back the initial energy level of the electrons for collision to occur properly. The more carbon atoms there are, the fuller orbital thus larger amount of energy will fall. The higher activation energy made difficult the supply of which, thus a larger amount is combusted improperly, and this can then explain the decrease in percentage of accuracy.Equally if there are more carbon atoms in the reactants, more products will form, and I had already investigated in my prediction that the reaction is exothermic, i.e. the energy given by the products is higher than the energy put in to the system due to the characteristics of different types of bonds. In this case, there are more bonds in the products, although the type of bonding may be different (? and ? bonds) that they have different energy levels.From my results it is possible of see that as the number of carbon atoms increased in a primary alcohol molecule, the energy output of it also increases. This had matched my prediction although the pattern between the expected and the observed is different.Evaluation:The results had shown a positive correlation between the set of results, however the results had also shown that the experiment did not accurately measure the energy output of the alcohols on graph 1. However there is potential to make more accurate the experiment by using method that could prevent as much heat loss as possible.Before it is possible to make further improvements on the investigation, probable errors must be identified and analyzed. It would consolidated my conclusion, in witch the particular errors are unidentified, if I had more evidence about the trend in the deduction of the percentage of accuracy, thus I would be a good idea to obtain the values of pentan-1-ol and hexan-1-ol. However if the equipments such as a variety of alcohols are not available, then more accurate methods can my applied to the current investigation to reduce the probability of anomalies occurring.First the heat produced by the reaction is not efficiently used to heat up the water, which can cause potential inaccuracies; some heat is lost to the surroundings and not taking in by water, because some would be conducted away by the apparatus e.g. the tin can some would be absorbed by the cylinder (not include in the calculation) and some lost through convection or move spontaneously to where air molecules have less energy due to nature. To solve the problem black painted tin cans which is able to absorb the maximum radiation given, and the infra red waved are able to heat up the water molecules. Yet not all part of the tin should be painted black, the inside and the outside of the sides of the tin can must maintain its shiny colour to prevent radiation given out by the heated up tin can.Some sort of insulation of the tin can is also able to avoid heat lost through conduction, consequently the tin can should be wrapped with wools to preserve the heat within. The apparatus that are purposed to preserve the heat are not all ideal, the cylinder used to increase the heat given to tin can should have had a higher heat capacity, because the draught shield was heated up but the large amount of energy, due to the large change in temperature, cannot and was not calculated. It would possibly be a good idea to use a better insulated draught shield, so that it would also by wrapped with wools and coated with silver paint to reduce conduction and radiation to the minimal. An enclosed and well insulated chamber can also increase the efficiency of the usage of the energy, by bring to a close the escape of the heat.Many other faults were caused by ineffectual apparatus. The hole that was used to light spirit burner acted as a drought, which provided oxygen which is an element in the equation of combustion, but this also had made the flame unstable due to the movement of the air. The thermometer was accurate 0.5 oC which could impact the final result, if the thermometer was accurate to 10-2 the results would be more accurate and more reliable. The shielding that are purposed to prevent heat loss can impede the process of putting off the flame, therefore the change in mass did not match the reading of the thermometer when taken, and the level of heat with in the chamber will not be consistent through out the experiment when attempting to distinguish the flame by capping the burner. This problem would be very difficult to solve that it would be difficult to have an enclosed system to prevent heat loss and to ensure that the flame can be distinguished easily.One other cause of error of my experiment was that the alcohols are not completely combusted because the activation energy cannot be reached when only little partition of the alcohols in the spirit burner are being burnt and not producing enough energy for efficient collision between particles so that carbon atoms are formed at the bottom of the tin can. The building up of the carbon also acted as an insulator that the heat cannot be conducted to the tin can and will impact on the results of my experiment. Again this is a problem that I have to face when the experiment is repeated, although the carbon can be displace after each experiment, but the effect of which during the experiment cannot be solved.Now that I think it is appropriate to introduce a different method which would guarantee the energy of the reaction can be accurately measured. In the current experiment heat loss to the surroundings and therefore the energy towards the water was not efficient, but if the surroundings, where heat is given to, is water then maximum percentage of energy released by the experiment would be given to water where it can be measured. The er ror occurred in measuring the mass was also a factor affecting the anomalous results, thus a given mass can be allowed to be completely combusted so that an accurate value can be obtained.Some of the energy given to water are lost, or transferred to the surrounding of the calorimeter which cannot be measured, the heat is transferred is because one system has more energy than the other. Knowing this if the calorimeter can be maintained at the same temperature as the water with, no heat transfer can occur through conduction, and when the calorimeter is concealed no further heat can escape by convection. In order to reduce radiation, as described above, the calorimeter can be coated in shiny colour. Rather than preceding the experiment in a spirit burner, where only a little mass of alcohol was being burnt which could not proved efficient energy output that the wrong proportion of which could be used to provide the efficiency for collision, and result in incomplete combustion.A larger mass could be burnt in a given length of time to produce more energy to secure further efficiency in collision. The appropriate apparatus which suites the description above would be a bomb calorimeter. (See diagram 1) The combustion would take place in the bomb where is cased with steel, which could with stand the impact of the explosion when alcohol being combusted and also conduct heat to the calorimeter. Within the bomb the reaction is triggered by a fuse-wire which is conducted to the mains, the fuse then burns the cotton attached to it and light the flame.The bomb is also well supplied with 25 atmosphere of oxygen, pumped in with a pipe, thus no draught is need. The bomb then will be placed in a calorimeter system filled with water, as stated above that maximum energy can be transferred in the water which can then be measured, the wall of this calorimeter will be filled with water and the temperature of which is controlled by a coil which equalizes the temperature so that heat cannot can not escape or get into the calorimeter. Because the heat cannot be transferred in or out of the calorimeter, the maximum temperature the system reaches would be almost, if not all the free energy of the reaction.As well as to discover the pattern among the primary alcohols, secondary and tertiary alcohols can also be investigated. We already know the relationship between the numbers of carbon atoms or the length of the carbon chain and the energy output, it would be equally significant to learn the science when the carbons are not in a chain or a irregular chain, and how a hybridized carbon if any at all is able to alter the results. Investigations could be among propan-2-ol, butan-2-ol, pentan-2-ol, hexan-2-ol, cyclohexanol and 2-methyl-propan-2-ol.
