Most People have heard of superheros. My hero isn't extraordinary or seen in movies, he lives in my home. Which hero do I, John Smith live with? The greatest father anyone could ask for. My dad is my hero because he served our miltary while taking care of three kids, is a great person, and went through a rough childhood growing up. Heros today are not as common these days. My dad proudly served 20 years in the United States Air Force. While away in foreign countries such as France, Greece, and Germany he never forgot his children, by sending home presents almost every week. Even though my parents divorced my father has tried his hardest to keep the family together by keeping a great friendship with my mother. Not only do I look up to him for his career, I look up to him for his upbeat personality from helping people in need of help to joking around with our food server he is always outgoing. My dad is the nicest, most understanding person I know. When ever we are out he is friendly to strangers. One day it was raining outside and he noticed someone trying to change their tire, he graciously stopped and helped. He is always looking out for other people.

Warren Buffett essays

Warren Buffett essays Warren Buffett is an American icon, but an enigma, of sorts, also. Investors, stockbrokers, analysts, and students of finance have studied the strategies of Mr. Buffett for decades, and more often than not, they are left with more questions than answers. Buffett was born in Omaha, Nebraska in 1930. His father, Howard Buffett, was an accomplished stockbroker and Congressman, and is primarily responsible for fostering Warrens love for number crunching and capitalism. In the archives of history, he will simply be remembered as the greatest stock market investor of modern times. At an early age in life, Buffett began to develop an affinity toward the art of investing. As a matter of fact, he was only eleven years old when he purchased his first shares of Cities Service Preferred. At $38 per share, these shares became the first baby steps in the life of who would eventually become Americas second wealthiest individual. As a teenager, Buffett turned his investing interests toward real estate. Buffett purchased some Nebraska farmland, and turned around to lease it out to a tenant farmer. That investment calmed his investment fever down until he became a senior at the University of Nebraska. It was there that Buffett was introduced to a book that would become the catalyst for his sparking his true entrepreneurial spirit. The Intelligent Investor, by Benjamin Graham, taught Buffett to ignore the trends that sweep Wall Street and instead hunt for stocks that trade far below their actual value. Buffett was a mathematical wizard, and the intense analysis of corporate balance sheets required by this method appealed to him. Once Buffett had graduated the University of Nebraska, he attempted to pursue a graduate degree at Harvard Business School, but this dream was quickly thwarted when he was denied admission. This turned out to be a blessing in disguise. ...

Sociology Essay Example | Topics and Well Written Essays - 750 words - 3

Sociology - Essay Example Humans themselves are emotional creatures; biologically each reaction is a chemical response to additional visual, chemical or other form of stimuli. At the very base of what makes a human’s emotional framework run is the chemical responses or neural framework that exists. This cannot of course discount the effect of ones surroundings, their culture and society on their reactions. In many ways we respond based on taught responses. While we are growing up we are adapting to the society that we are directly involved in, and the cultural variances that may accompany that society. We react to some forms of stimuli based solely on our understanding of those stimuli which was trained into us from birth. An example of this could be seen by using a simple observation of a set of parents and their progeny, by observing the individual and separate reactions to different forms of stimuli it becomes readily apparent that the child will likely mimic the adults in many areas. A group is a n umber of people continuously interacting with each other in a structured way according to shared morals or social outlooks. A primary group would represent a family unit, such as parents and children and possibly grandparents as well. In my life it would be my parents and my significant other. Because our contact is based on a large amount of contact and an understanding of each other in more than a few hours a week at work or in meetings with various social gatherings this would be a primary group. An example of a secondary group would be fellow students with whom I share several hours a week in a similar manner though we are unlikely to have much actual face to face time and the time we spend together will likely be more cohesive and rule based. Max Webber’s six-traits of bureaucracy according to Professor Alazzawi are a formal hierarchical structure, management by rules, organization by functional specialty, a focused mission, purposely impersonal and employment based on t echnical qualifications. This organizational form works well within a secondary group however, would likely cause problems within a primary group. Humans thrive on being able to â€Å"personalize† everything around them, and while this has its obvious drawbacks within society as a whole it does make it difficult to promote long lasting, self-sustaining relationships within any group. There is a level of inflexibility that would likely cause frustration and in fact in many organizations that are secondary groups frustration with the role being played by the individual is often voiced. The sexual revolution was the extremely liberal approach to human sexuality as embraced in the 1960’s it accompanied for the most part a large amount of experimentation in drugs, political approaches and lifestyle changes as well. There have been many various views applied to the â€Å"why† of this revolution, one that I tend to embrace is that this revolution is the result of the c ontinued stifling of free thought along with the sexist and racist approaches embraced and taught leading up to this point. It was a complete rebellion against the status quo as it were. As for the various issues discussed I believe that sexual violence in the form of rape, child sexual abuse and other related

Product design Essay Example | Topics and Well Written Essays - 750 words

Product design - Essay Example Usually, the failure of a new product results because of the weakness of its product design. (Roqueta, 1992) One of the prominent weaknesses in this portable CD player is that it has buttons whose placement is not too comfortable. The placing is awkward, thus making it difficult for the consumers to use. Moreover, since the CD player is portable, the usability and smoothness of the buttons play a major role, since they have to be used on the go. But rather than being extremely user friendly, their placing is not up to date, making it inaccessible to the consumer easily. These buttons are very small in size, thus this result in pressing some other button when the consumer intends to press a specific button. The button of switching between the AM and FM also looks very out of place, since its look is very different from the rest of the player. It is made of very thin rubber, which doesnt complement the stylish outlook of the remaining CD player. The design is perfect when the entirety is in congruence with each other. Second issue with the product design is that of the SonicStage software that comes with the player. The problem with it is that it is too slow in function. The software is supposed to compress the music of consumers, such that the quality is maintained and it can easily fit into one single CD. But the problem starts when the software is converting the MP3 format of the song to the ATRAC format of the Sony CD player. This process is very sluggish, and takes place at a snails pace, thus eating up a lot of time of the consumer and also increasing their frustration with the slowness of it. Moreover, as promised that the quality of the songs would not change, this does not happen to. The songs are now of lesser quality than they originally were, after the conversion has taken place. In addition to that, the SonicStage software

Romanticism Essay Example | Topics and Well Written Essays - 250 words - 1

Romanticism - Essay Example Romanticism influenced music and literature, as well as visual art (Tekiner 60). For instance, the Sturm und Drang movement of Germany that exited from the late 1760s to the early 1780s was mainly minor-key musical and revenge-influenced literary, which caused a handful of image artists painting horrifying scenes (Tekiner 60). For a proper case, there is the Nightmare by Henry Fuseli that was painted in 1781. Some artists were into these movements until their relevant ends, whereas others maintained elements of Romanticism as they shifted to new directions (Tekiner 60). The main themes in romanticism included democracy, revolution and republicanism, transcendence and the sublime, the influence of imagination, the source of inspiration and genius, extreme mental states and proto-psychology and finally the natural and nature (Tekiner 79). Radical Romantic-age politics were overly optimistic concerning human nature, always reasoning that human beings are vitally good and their vices are raised through poor education. Republican and democratic movements always advocated for mass education and equal wages as a way of freeing the human heart, as well as the mind from ignorance and poverty —and the ills and vices, which materialize from these evils (Tekiner

Trends in Social Welfare and Crime Control

Trends in Social Welfare and Crime Control Georgiana Raluca Andrei Explain and illustrate the claim that contemporary trends in social welfare and crime control policy are indicative of a punitive turn. In contemporary Western societies the division between crime control and welfare is blurred, with the two coming together to produce a complex and sometimes ambiguous policy mix, within which crime control policy substitutes for welfare but may also incorporate welfarist notions of care and protection. The threat and fear of crime has impacted on public and policy attitudes towards welfare and crime control through a process of innovation in law and policy that blurs the boundaries between traditional crime control and welfare fields. Punitivity is a term which means that systems of punishment have become harsher and that though measures have a large degree of popular support (Cochrane and Talbot, 2008, p. 11). Allan Cochrane and Deborah Talbot (2008) suggest that the security/insecurity nexus illuminates a set of connections between the worlds of social welfare (broadly, the search for security) and crime control (broadly, responses to threats of insecurity). The policy worlds of social welfare and crime control need to be understood in relation to one another. In the contemporary world, demands for security and fears of insecurity are present and visible in personal lives, in political agendas and in policymaking domains. The search for security is likely to be unfinished as efforts to ensure security paradoxically heighten personal and societal senses of insecurity, in turn leading to further searches for more security. The emergence of security as a personal, governmental and policy concern is reflected in the work of social theorists and policy analysts, who have debated how the search for security may be understood as shaping social relations and social policy. There are competing app roaches to achieving security. Some emphasize the need to extend criminal justice and legal systems to address the behaviors of those that threaten ‘our’ security; others highlight the need to address broader social divisions, inequalities and problems that undermine the security of societies. Security is a concept with multiple dimensions at individual, group, national and global levels. It’s sometimes argued that the responsibility for achieving security rests with us as individuals rather than with governments. Collective responses to the search for social and economic security are visible in the work of institutions, such as trade unions, credit unions, charities, businesses and governments. These organisations and institutions work to ensure economic security through work, welfare benefits, or pensions, and health security through medical support and care in times of illness and infirmity. They also work to ensure the air we breathe is free from pollution, the water we drink is clean, and the food we eat is uncontaminated. The loss of any one of these will undermine the security of individuals and potentially of societies. Government seek to defend the nation from perceived threats, such as terrorism, political dissent and foreign aggression, and to secure the resources necessary to support their economies and population’s water, food and energy. They enter into international agreements with other governments to address threats of global crime. For example money laundering and trafficking of humans, environmental degradation such as problems of global warming, pollution and waning biodiversity; and also to cooperate with other countries on matters of policing and justice. Security has meanings at every level of human existence from the most private needs and relationships to the broadest currents of international relations and global problems. Focusing on different sources of insecurity leads to different ideas about how we can achieve security. Focusing on security may heighten the anxieties and feelings of insecurity whether now or about the future. They may lead us to try to achieve our own security and that of our families in ways that make others less secure. For example, securing the houses with cameras, alarms, and fences, a nd having police officers visible on the streets, may make us feel safer. But it may also make others more fearful of crime. Actions taken by governments in the name of protection from internal and external security threats sometimes come at the cost of personal freedoms and civil liberties of entire populations. Measures used in pursuit of security often fail to deliver it, and may often, paradoxically,increasea sense ofinsecurity. Security is increasingly being sought (by those who can afford it) through private solutions. Examples of such solutions include living in secure residential enclaves or driving sports utility vehicles (SUVs). This recourse to private solutions represents a form of risk management and social retreat. The media is one of the main drivers of insecurity. The news organisations create a false picture of the problem of crime, exaggerating certain categories of offending, such as random and violent attacks by strangers, and ignoring or underplaying other types, such as the crimes of governments and powerful organisations, or domestic crimes within the family. This can result in a distortion of public perceptions about crime, with greatest level of fear attached to crimes which are least likely to affect them. It has been noted that fear of crime often exceeds the actual risk of personal harm (Jewkes, 2008, p. 33). As individuals, people seek to manage risk by creating safe spaces in a variety of ways. At one extreme these strategies include narrowly delimited places of retreat for personal safety, which might incorporate a range of security devices including barred windows, spy glass, intercom systems. Families are a site of both individual and social security; that is, they are seen as being a key social formation that ensures personal security, as well as a ‘building block’ of society and social order. Families have tended to remain at the top of political and policy agendas, with strong families being equated with strong societies. However, families can also be understood as sites of insecurity – for individuals, who experience family life as harmful or neglectful, and for societies more broadly. While recent debate has centred on whether family change represents some kind of social decline or descent into social disorder, ‘family breakdown’, ‘problem families’ or ‘failing’ families are not new anxieties. For many decades, families who were thought to be ‘failing’ in some way have been a target of social welfare interventions and, increasingly, of crime prevention strategies. Families mirror the contradictio ns in relation to security – they offer a range of securities and act as sites of safety and social welfare, but they also present a range of insecurities, threats and dangers. This means that families are the focus of not only social welfare policy but also crime control policy. Some families are perceived as ‘better’ and more competent than others, and some families are perceived as problematic, disorderly and threatening, and therefore in need of different kinds of policy intervention, including crime control and social welfare policies. These perceptions can be normative and influenced by assumptions based on class, ethnicity and sexuality. Families are closely connected to child welfare issues. Contemporary anxieties about the nature of childhood, together with conflicting ideas about children – as vulnerable and in need of protection and care, and as threats to society and in need of control – are reflected in child and family policy intervent ions. These tensions and ambiguities about children inform social policies aimed at providing both welfare support and reducing crime. Antisocial behaviour and hate crime legislation can both be understood as sites in which the criminal justice system has been extended into new areas. In this way, there is an increasing shift to a more punitive approach within criminal justice systems, particularly in the UK and the USA. Anti-social Behaviour Orders (ASBOs), were part of an increasingly large and complex set of New Labour measures for managing and governing populations. Wacquant stated that â€Å"various neo-conservative think tanks in the USA were able to valorise the diminution of the social or welfare state† and that punitive measures were spreading from USA through Europe. According to the article, the USA/UK policy is being defined by â€Å"mass imprisonment, curfews, interventions based on risk assessment rather than need, zero tolerance, naming and shaming† , becoming more punitive and affecting everyday social relations. States all around the world seem to take a puntive turn to young offending. The depth of the punitive turn in USA in the 1990s is undeniable and Wacquant’s thesis is being supported by quantitative data that shows an increase of children detained in â€Å"juvenile secure estate† in UK and Wales. The American intolerance for those under 18 is getting more popular in the rest of the world. A punitive turn in juvenile justice in a number of countries in Western Europe has been more repressive but not necessarily more efective. It has achieved a political legitimacy to the detriment of traditional principles of juvenile protection and support. The article provides important data that shows the high number of immigrants and minority groups under arrest or in detention and the more punitive elements of juvenile justice. It is difficult to estimate the total amount of the juvenile secure population in various countries at various times due to differences in defining a child, a juvenile. Different countries have different ages of criminal responsability, there is also a difference in definition of offences which make it difficult to compare the countries. Security cannot be fully understood without reference toinsecurity, the idea of security implies the threat of insecurity, so that insecurity and security are intertwined. The ways in which welfare and crime control policies intersect and are entangled help to shape experiences of social inequality. Families can be sites of both security and insecurity. Identifying differences in experiences of security and insecurity is important for understanding, in turn, the different responses of policy and legislation to the (in)securities of family lives. In order to keep under control juvenile and adult crime rates, the system becomes punitive and adopts extreme solutions that will only lead to more drastic consequences.

Art Therapy: Helping the Mind and Body :: Health, Treatment

Can art imitate life and healing? The use of art therapy began in the early 20th Century, used by a myriad of education and mental health practitioners, as a means of therapy for children and, eventually, adults (American Art Therapy Association, 2011). Art Therapy is beneficial in treating victims of illness from mental issues, including sexual abuse and schizophrenia, to physical disease like HIV/AIDS and fertility in women. Used in association with group talk therapy, art therapy has been proven to be effective with sexually abused children and with those patients who suffer from more severe mental disorders like schizophrenia. In a study of South African girls, Natascha Pfeifer found that art therapy helped girls who had been victims of sexual abuse to improve self-esteem and with symptoms of anxiety. Pfeifer evaluated 25 sexually abused girls from 8 to 11 years old. The program was based on Gestalt’s client-centered and abuse-focused principles (Pfeifer, 2010). â€Å"The Solomon four-group design was used to investigate the efficacy of the intervention, the Trauma Symptom Checklist for Children and Human Figure Drawing were used as measures for assessing symptom change† (Pfeifer, 2010). The girls were asked to explore feelings associated with the abuse they had experienced. In addition, they were asked to draw different feelings and discuss them among the group. â€Å"They were then ask ed to draw or paint a ‘happy box’ and an ‘unhappy box’ in which their feelings could be stored. Hereafter the children drew the person who abused them (as an animal, shape or colour) and their feelings toward the perpetrator. In order to further address any unfinished business regarding the abuser, the girls were given the opportunity to verbally or physically express their feelings, which could then be placed in the happy or unhappy box. This was followed by a discussion on how it felt to express these feelings† (Pfeifer, 2010). The results showed that the girls in the experimental group had lower levels of depression and anxiety than those girls who were in the control groups. Self-esteem seemed flat for all groups, according to Pfeifer. â€Å"The findings of the present study suggest that the programme does not target low self-esteem as successfully as depression and anxiety. Alternatively, the findings may reveal that the HFD is not sensitive to changes in self-esteem symptoms† (Pfeifer, 2010). In targeting s chizophrenia, art therapy has had more promising results in aiding with rehabilitation and socialization. In 2003, Virginia R.

Do something that I have never done before Essay

hen I heard that the professor asked us to do something that we have never done before, I got excited at the moment. It made me feel like I got a good reason and opportunity to try something special. I took something really crazy such as skydiving or boarding into my consideration in the first. Afterward, a flash of idea came upon while I was talking about cooking with my friend; I wanted to cook lobster, a live lobster. I watched a famous TV show named â€Å"Take home chef† before, which is a show that basically teaching people how to cook. I watched one episode that was teaching people how to cook a live lobster. I dimly remember that the whole procedure to cope with live lobster was quite challenged for me. First of all, I have rarely cooked. Furthermore, I have never purposely taken any live of any creature before! After making the decision, I started to search information and some videos, which show people how to deal with live lobster, and also some recipes for cooking lobster cuisine. I chose the backed way to make my first lobster dish, which seemed easy but not as boring as the one just simply steam it. And in general, there are three ways to kill lobster. First, freeze it to death; second, boil it; the last, do bloodletting until it die. I picked the most friendly and the fastest way for the beginner, which is boiling. To get live lobster, my friend and I went to Redondo Pier. In that pier, you can get all kinds of fresh seafood that people come to their mind. I saw approximately twenty to thirty lobsters lively swinging their claws and legs in the pool; suddenly, somehow I felt a bit guilty and scary I would kill these lives in person later. Having both nervousness and excitement, we drove back home and got ready to be a lobster killer for the very first time in my life. When I took of the lobsters from the bag, they were still moving their claws and legs. â€Å"Don’t you really dare to kill me by your own hand? † I felt the lobsters were trying to deliver this warming with their staring eyes. I was afraid that I would be gripped by its claws so that I didn’t dare to cut the ties that bound its claws. I directly put them into the boiled water. The first few minutes, the lobsters were still moving. I suddenly thought of the recipe says that lobster doesn’t feel pain and will be dead in ten seconds; however, it may keep moving because of  muscle spasms. This made me feel more creepy while seeing them moving and gradually stopping in the boiled pot. After around five minutes, I pulled it from the water and submerged it into ice water to cool it. Then, here came another tough part: splitting its head from the body and then cutting the body into two pieces. I carefully follow the instruction from the recipe to cut the lobsters from the top to the base of its tails. I felt accomplishment when I successfully split them into pieces. Afterward, I spread butter, pepper and lemon juice on it; and the last step was put them into the oven. After waiting nervously for eighteen minutes, an aromatic backed lobster cuisine came out. This was my very first time to cook all by myself, and the tough thing was that I had to deal with the lobsters, which were still alive. Though the procedure was a bit hard for me as a beginner of cook, I still enjoyed this experience. Above all, I had a delicious lobster cuisine for a dinner, and got a great accomplishment for that.

Effect of Concentration on the Rate of Reaction Essay Example

Effect of Concentration on the Rate of Reaction Essay Example Effect of Concentration on the Rate of Reaction Paper Effect of Concentration on the Rate of Reaction Paper Introduction: In this experiment, we utilized the ability for the iodide ion to become oxidized by the persulphate ion. Our general reaction can be described as: (NH4)2S2O8 + 2KI A I2 + (NH4)2SO4 + K2SO4 (1a) However, we know that in an aqueous solution, all of these compounds except iodine will dissociate into their ionic components. Thus we can rewrite the equation in a more convenient manner: S2O82- + 2I- A I2 + 2SO42- (1b) It is important however to note that the NH4 and K ions are still in the solution, they are just unreactive. In order to measure the rate of the reaction, the conventional method would be to measure the species in question at certain times. However, this would be inconvenient, especially for a three hour laboratory period. Since the iodide ion can be oxidized by the persulphate ion, we can use sodium thiosulphate to be an indicator of the presence of iodine in the solution. For this experiment, we can simply calculate the rate of the reaction by timing the amount of iodine being produced in several runs. The reaction between iodine and sodium persulphate can be depicted as: I2 + 2Na2S2O3 A 2NaI + Na2S4O6 (2a) Similarly, this reaction above can also be simplified due to dissociation of all the ions except for iodine and persulphate. I2 + 2S2O3 A 2I- + S4O62- (2b) An interesting property of reaction (1) is that it produces a brilliant violet colour. However, this violet colour only results in the presence of iodine, or in other words, when iodine is being produced in the reaction. If sodium thiosulphate is added to reaction (1), than as long as there are two moles of thiosulphate for every mole of iodine, the solution will be colourless because the iodine is being used up in reaction (2). However, as time passes, the thiosulphate must run out at some point, and when it does, the violet colour will appear. Timing how long it takes for the violet colour to appear will allow us to calculate the rate of the reaction. In this experiment, 5 mL was also added in order to provide a more accurate measure of the time at which the colour first appears. Starch is helpful because it forms a blue complex with free iodine. Once we have the time elapsed for each run, we can calculate the rate of the reaction by applying the equation: Rate = -a  S2O8-2 / a  t The change in S2O8-2 is simply half the concentration of S2O3-2 because in reaction (2), the consumption of iodine and persulphate has a 1:2 ratio. Thus, the consumption of iodine can be seen as half the consumption of persulphate (S2O3-2). After calculating the rate of the reaction, the rate constant can be found by using the equation: Rate = k [ S2O82-]m[I-] n By comparing 2 sets of data at a time from 2 different runs, the order exponents m and n can be calculated, and thus, we can write the rate law for the iodide-persulphate reaction. We should also expect that the expected relationships between the concentration of S2O8-2 and the rate of reaction and rate constant might not always be extremely accurate in this experiment. When dealing with ions, we must always consider the ionic strength of the ions involved. The rate of the reaction will increase as the ionic strength gets stronger, thus, we will not always see a perfect linear relationship between [S2O8-2] and the rate of the reaction and the rate constant. The purpose of this experiment was to perform many trials of the same experiment, varying only the concentrations of certain ionic compounds in order to determine the affect of concentration on the rate of a reaction. By varying the concentration of different compounds for each run while keeping other factors constant, we were able to obtain experimental data that would give us a relationship between concentration and reaction rate.

Moda Operandi A New Style of Fashion Retail Case Study

Moda Operandi A New Style of Fashion Retail - Case Study Example The essay "Moda Operandi A New Style of Fashion Retail" discovers New Style of Fashion Retail. Moda Operandi dealt with demand and tastes’ uncertainty in fashion. It also addressed the conditions (commercial and aesthetic which caused inefficiency of the system and messed about the most creative pieces of the designers. This organization allowed direct access to runway pieces and facilitated the purchase of great designs that buyers kept away from due to lack of mainstream appeal.

Critical Observation Paper - Essay Example tegies appropriate to the situation (Asch, 2001). To better illustrate the importance of study of psychology and research in this field, let me cite a concrete example. As human beings, we are born with the need to socialize and interact with other people. One interesting example of social behavior that is observed in some individuals as they interrelate with others is their dependency on other people. Dependent behavior, according to McDavid (1994) is one of the most common forms of human activity. I know of a person who cannot act nor move around without a companion. This person is over than 35 years old already, still single, physically able and works in a public academic institution. She is an attractive lady who actively participates in religious activities in her Church. However, her actions always depend on the presence of somebody as if this other person provides some sense of security on her part. She always keeps a company during mealtimes, whenever riding a public transportation on her way home, even when simply going from one office to another within the same building.

To some who are not into the study of psychology, the behavior of the lady may appear to be a little "weird" or extraordinary to those who are into studying other people's behavior through observation, it helps to explain things and facilitate better understanding among
