Apparently, different states have their ain concrete state of affairs and typical phenomena. In the paper, I would wish to discourse some effectual and utile bar and intercession attacks depending on Hong Kong. There are different theoretical accounts of intoxicant intervention such as cognitive behaviour theoretical account, medical theoretical account, biopsychosocial attack and so on. Different intervention and intercession program has different focal point and characteristic. Just like instruction plan, a sort of prevalent attack which applied in bar phases, people hold different version. The instruction plan is uneffective and has non offered utile cognition and accomplishments to chair and cut down the intoxicant ingestion. ( Collins A ; Keene, 2000 ) . Collins and Keene stated that that while degrees of cognition can be increased, supplying information on intoxicant issues and jobs does non take to behavior alteration . ( 2000, p.97 ) On the other manus, some research workers think instruction plan is necessary especial in bar phase. Prevention phase are ever related with instruction , which provide utile information and cognition to alarm people remain off from drugs and assist them do a accurate determination when confronting intoxicant and drugs.

Cognitive behaviour attack is the most appropriate attack for societal workers. Because in the attack, there are tonss of accomplishments and methods belong to the societal work s repertory and it stress the duty, value, authorization of clients. ( Collins A ; Keene, 2000 ) .Ray and Ksir ( 1999 ) stated that Some behavior-management attacks have accepted controlled imbibing as a desirable result and have attempted to learn methods that will copy intoxicant intake. ( P.257 ) . Ray and Ksir argued that behavioural attack can learn clients get bying accomplishments. Some behaviours are taught in bar plans, moreover, healers besides help clients to concentrate on high hazard state of affairs and learn them how to acquire through the hard times. ( 1999 ) . Gorgulho and Tamendarova figure out a new attack called societal norm selling.they stated that it is a comparatively effectual in diminishing utmost imbibing and it stress on equal norms and force per unit areas. Social norm selling apply assorted formal and informal manner to offer accurate information of imbibing forms to those immature people, which can extinguish misconceptions and cut down utmost drinking. ( 2008 ) . Besides, brief intercession and circle of alteration theoretical account are mentioned often in many governments. Brief intercessions are suited for immature intoxicant maltreaters because these immature extreme drinkers ever think the intoxicant ingestion is elementary and no necessary to seek aid. Brief intercession can be a critical first measure in intervention since it provides advice, appraisal and referral. ( Gorgulho A ; Tamendarova, 2008 ) . Cycle of alteration theoretical account is a practical measure to assist cut down drug maltreatment. It focus on seeking the trigger that lead to drug maltreatment, and understand the hazard state of affairs which can supply effectual backsliding bar schemes and offer self-talk. ( Dominelli,2009 ) . Prevention attack can assist underage adolescence stay manner drugs to some extent. Spruit stressed that traditional bar plan aimed at bettering pupils behaviour accomplishments such as learning them how to get by with peer force per unit area and do accurate determination. Secondary bar besides called injury decrease, which used by healthy attention sector and societal attention sector ; assist forestall wellness deteriorating in the hereafter. ( 1998 ) . Beside these effectual and professional theoretical accounts and attacks, societal workers should see the intervention environment and household environment of clients during the whole bar and intercession procedure. To the minor striplings who are alcohol abuser, most of them are vulnerable and down, so they seek solace from intoxicant. When confronting this sort of clients, a safe and trustworthy environment is critical. Muisener argued that when confronting to the clients who have been alcohol abuser or intoxicant victims, societal worker should supply a safe environment. ( as cited in Collins A ; Keene, 2000, P.103 ) . societal workers can smooth relationship -building, particularly in the formation of societal networkers that can give people a feeling of being valued, appreciated and belonging to a broad circle of people. ( Dominelli, 2009, p.121 ) Actually, non merely the intervention environment is of import to the adolescents, their household milieus besides influence their behaviour and emotions. Due to tonss of immature drinkers are influenced by household and equal group in school, so school-family plans seem utile and effectual. The plan aimed at bettering the household working to forestall imbibing jobs by household member and adolescence. ( Gorgulho A ; Tamendarova, 2008 ) The state of affairs in Hong Kong: Actually, the intoxicant maltreatment job among adolescents in Hong Kong has its ain features such as alone cultural background, public attending, the ground of household and equal influence and so on. All the clip, intoxicant imbibing is viewed as a prevailing amusement and single life style and has non being viewed as a serious societal job. From my point of position, the intoxicant cultural is playing an of import function in the whole societal activities. Peoples will hold a drink after work to alleviate force per unit area. Peoples besides will imbibe alcoholic drink when some happy events or jubilations go oning. Lou and Shek stated that in Chinese civilization, people ever drink when they meet friends or holding household assemblage. Because these societal -oriented grounds, tonss of adolescents begin to imbibing. ( 2006 ) . In Hong Kong, the adolescents intoxicant maltreatment is ever associated with five psychosocial factors. They are academic public presentation, temper, attitude, household attitude and organized condemnable groups engagement. Further, Lou and Shek suggested that intoxicant maltreatment brings about many negative effects to adolescents. The influence include behavioural job such as combat, sexual behaviour after rummy, take parting in offense organisations and so on ; healthy job such as liver or tummy hurting and household struggle. ( 2006 ) . Therefore, the intercession and bar program should be established from the five positions. My bar and intercession program: Harmonizing to the specific state of affairs in Hong Kong, I suggest the prevention/ intercession program pay more attending on adolescents psychological state of affairs, populating and analyzing environment. Because of both of them are the most important elements which influence the hereafter development of adolescence. At the beginning, although there are tonss of arguments about the effectivity of instruction plan, I still see instruction plan is a critical portion, particularly in the phase of bar. Actually, how to use instruction plan to better adolescents consciousness is important. The accomplishments, methods, techniques will find whether the plan is effectual or non. Prevention program: To those adolescence that neer drink intoxicant before, the bar program should concentrate on two parts: instruction and communicating acquisition. Education plan: Education plan can supply them current way and utile information. Adolescence is an of import period which imposes a important influence on a individual s whole life. During the period, kids ever full of wonder, and like seeking something disputing and experient alteration in both mental and physical development. At this clip, as a societal worker, we should give more advices and pay more attending in instance of them go astray. However, in the instruction plan, we should offer appropriate advice, if we emphasize do non imbibe to much, it will convey approximately negative effect. For illustration, most adolescents at this age are rebellious and they view imbibing intoxicant as a cryptic escapade and seek it in secret. Therefore, in the instruction plan, those sorts of deadening talks possibly uneffective, I suggest societal workers should utilize several vivid signifiers such as movies or existent experience to exemplify the negative consequence caused by intoxicant. Communicating A ; larning workshop Social workers can join forces with school instructors and staffs to form some activities to assist pupils understand and acknowledge the disadvantages of utmost imbibing. For illustration, ask foring school pupils visit several establishments which help bring around intoxicant maltreaters. After sing, societal workers can promote them hold a treatment or compose a contemplation to depict their ain feelings. By this method, adolescents can grok hazard of utmost imbibing and organize their ain sentiment instead than accomplish sermon passively. Intervention program: To the adolescence who is of all time alcohol user or current intoxicant user, the focal point of attack is different from bar program. Intervention program emphasize amending the behaviour and assist them retrieve every bit shortly as possible in both mental and physical wellness. Appraisal Those adolescents who are utmost imbibing in Hong Kong are ever associated with similar psychosocial correlativity. Some of them are influenced by equal group, some of them are lack of household support and corsets in an unsupervised state of affairs which lead them seek solace from intoxicant. Merely understanding the grounds and triggers behind, we can happen out sound schemes to assist them. The appraisal should include person s household background and state of affairs, person s drink form and their perceptual experiences about intoxicant. From the appraisal, societal workers can get person s accurate information which facilitates set uping following program. Family-school attack From the five psychosocial elements associated with adolescent intoxicant maltreatment in Hong Kong mentioned above, we can happen that Adolescents are easy influenced by their household members and peer schoolmates. From the position of household, societal worker should pass on with the client s parents on a regular basis and happen out the disadvantage of the household operation and parenting form. Then give them advice and inquire the parents to care about their kids more often. From the position of school, societal workers can corporate with instructors and staffs to place the triggers of intoxicant maltreatment like academic emphasis, hapless relationship with schoolmates and so on. And assist them acknowledge the bad state of affairs and effect. Bettering intervention environment Tonss of adolescents are less likely to seek professional aid to cut down their alcohol addiction. On the one manus, a portion of them view intoxicant is elementary, on the other manus, they ever feel vulnerable and incapacitated, they are fear to confront their psychological job. Therefore, societal worker should supply a trust and safety environment. At the beginning of the guidance plan, we can state clients we will maintain secretiveness of their basic information and give them more support and encouragement. Relaxation accomplishment preparation There must be some ground lead to people particularly adolescents addicted in intoxicant. And depression, anxiousness and emphasis these sorts of emotional reactions are frequently involved with the intoxicant maltreatment. During the intercession program, societal workers can use some relaxation accomplishments to assist adolescent quiet down. Helping them release and cut down emphasis and modify their temper. By the method, we can extinguish their tenseness and assist them remain off alcohol measure by measure.

Globalization, Poverty and Labor Structures essays

Globalization, Poverty and Labor Structures essays Globalization, accumulation of capital and therefore economic restructuring are crucial elements in the way the world is organized and wealth is distributed. The development of capitalist world economy is heavily dependent on the particular division of labor that governs a nations market. The concept of International Division of Labor (IDL) reflects the vertical relationship that exists among First World countries or developed countries and Third World countries or the developing countries. One should note that while the terms First world, Third world, developed and developing countries are often used in a pejorative way. It is not the intention of this essay to contribute to the discursive reduction of the countries discussed, nor is it the intention to reinforce binaries that allow for a vertical relationship of power to exist among the privileged and the less fortunate. For the purpose of this essay, IDL will refer to the new system of the world economy where the continuous growth of the capitalist countries has been accorded the gravest importance. In this model, worked out by the Organization of Economic Cooperation and Development (OECD), the organization of the Western industrial countries has been equated to the relocation and export of labor intensive and therefor labor-cost-intensive production processes to developing countries. This economic restructuring manifests into the use and abuse of Third World workers, because of their low wage levels and minimal requirements for safe work conditions, giving rise to establishment of Free Trade or Production Zones, or World Market Factories in countries such as the Philippines, Malaysia, Mexico, Sri Lanka, and Thailand. The relocation of industries, particularly the textile and garment industries, the electronics industry and the toy industry has dictated a certain labor order where women are the op timal force for the capitalist accumulation process on world scale because the...

For case study about Tort and Negligence (course Legal Foundation for Accountants) - Research Paper Example A tort law can be described as a civil wrong not arising from a contract and in the case of negligence, one should owe due consideration to one’s neighbour (Capiro Industries vs. Dickman 1990). Negligence therefore, can be described as the act of doing something a reasonable man would not do and a plaintiff must prove in such a case that the defendant owes a duty of care (Donoghue V. Stevenson 1932). In this case, it is of paramount importance for the claimant to be able to prove that the negligent behaviour of the defendant which is Bull Pty Ltd would have caused the loss of the lucrative contract to supply the toys in order to win the claim that the subsequent loss after the action of the Dan could have been avoided in the event that he would have acted within reasonable limits.

The Great Gatsby Essay Example for Free

The Great Gatsby Essay They say that money is â€Å"the root of all evil. This novel exemplifies how the characters live for money and are controlled by it. Love and happiness cannot be bought, no matter how much money was spent. Tom and Daisy were married and even had a child, but they both still committed adultery. Daisy was with Gatsby and Tom was with Myrtle. They tried to find happiness with their lovers, but the risk of changing their lifestyles was not worth it. They were not happy with their spouses but could not find happiness with their lovers. Happiness cannot be found or bought. Daisy lost her love and respect for Gatsby when she found out he was a bootlegger. The important thing was not just having money, but where they money came from. In F. Scott Fitzgerald’s novel, The Great Gatsby, money is a prominent theme. The author shows that money is earned and spent in very specific ways. Each character’s relationship with money allows the reader to see their personalities more clearly. In the beginning of Chapter Two, Nick and Tom Buchanon have just met Tom’s girlfriend Myrtle. The three of them are on their way to Tom and Myrtles apartment when an elderly man selling puppies on the side of the street catches Myrtle’s eye. The author explains, â€Å"I want to get one those dogs, she said earnestly. I want to get one for the apartment. They’re nice to have- a dog-I think its cute†¦Is it a boy or a girl? She asked delicately. † â€Å"It’s a bitch,† said Tom decisively. † Here’s your money. Go and buy ten more dogs with it† (pages 27-28). Tom’s actions and choice of words when he is buying the puppy for his girlfriend Myrtle show the reader that he does not have respect for women. The way Tom throws his money around illustrates that he believes he, because he has money, is better than the person selling the puppies. Fitzgerald uses the money theme again when he writes about the parties that his characters attend. He notes â€Å"I like your dress, â€Å" remarked Mrs. McKee, â€Å"I think it’s adorable. †Ã¢â‚¬  Mrs. Wilson rejected the compliment by raising her eye brow in disdain. † â€Å"It’s just a crazy old thing,† she said. † I just slip it on sometimes when I don’t care what I look like† (page 31). Myrtle rejects the compliment on her dress because she wants to portray herself as a woman who wears extravagant clothing. When in reality, the dress that she is wearing was a dress that Tom had bought for her. It is actually the most expensive dress that she owns. Prestige and money are so important that she lies to impress those around her. In the 1920s money was very abundant. This was known as the golden age. People were very materialistic during this time period. The wealthy families in the novel such as Gatsby or the Buchanons were always trying to impress rather than trying to be themselves. This was a period of drinking, partying, and spending which was best portrayed by the Buchanons. They seem to be very self-centered people who couldnt give up a bit of the ritzy life to take care of their own child. Nick Carrows, the narrator of the novel differentiates and alternates between the two different types of money in the novel. East Egg and West Egg. The West Egg is the less fashionable side of Long Island where Gatsby and Nick live. The East Egg is the fashionable side of Long Island where the Buchanons and other old money people live. Those living in West Egg have wealth, but they have earned it themselves, but the people in East Egg have had money in their families for generations. People from East Egg only associate themselves with other people from East Egg and are rather ashamed of people of a lower status. The author explains a situation with Tom on the train, â€Å"Mrs. Wilson sat discreetly in another car. Tom deferred that much to the sensibilities of those East Eggers who might be on the train† (page 26). Tom is dating a girl named Myrtle who is from the Valley of Ashes; The Valley of Ashes is a very poor area. She has no money to her name whatsoever, and that is why Tom will not sit in the same car with her on the train. He will not allow people to see that he associates with someone of her station in life. Nick sees firsthand how different people from West Egg act compared to those from the East Egg. The author writes, â€Å"Come along, â€Å"he said- â€Å"but to her only. † Gatsby looked at me questioningly. He wanted to go, and he didn’t see that Mr. Sloane had determined he shouldn’t†¦My Go, I believe that man’s coming,† said Tom. â€Å"Doesn’t he know she doesn’t want him? (page 103). Gatsby was invited to a party at the East Egg as a form of an apology for having to leave Gatsby’s house. Gatsby is from West Egg; he completely missed the apology and took it as an invitation. The authors point is that even though people from West Egg and East Egg both have money, they live completely different lifestyles and behave complet ely differently. The author uses money to reveal several different traits in the novel. All of the characters personality traits in the novel are based off of wealth. Without the money, these characters would be nothing. Gatsby is known for his money and attitude. The author writes, â€Å"I heard the familiar â€Å"jug-jug-sput† of a motorcycle, and a frantic policeman rode alongside. † All right, old sport, called Gatsby. Taking a white card from his wallet, he waved it before the man’s eyes. † â€Å"Right you are,† agreed the policeman, tipping his cap. â€Å"Know you next time, Mr. Gatsby. Excuse me! † (page 68). Because of Gatsby’s past he has been able to meet popular people in his lifetime and acquire special privileges over the years. The only reason Gatsby can act this way and get away with it is because of his wealth. Another important character who portrays that her personality is shaped by money and wealth is Daisy. She lives a rich lifestyle but is forced to live with a man she can’t stand. The author explains, â€Å"Everybody thinks so-the most advanced people†¦The instant her voice broke off ceasing to compile my attention, my belief, I felt the basic insincerity of what she had said† (page17). Daisy is talking about how she knows so much because she has traveled the world and talked to interesting people through out her life. The author uses Daisy as a prime example to show that while money may provide opportunities in life, it is what you do with those opportunities that matter. If Daisy didn’t have money, she wouldn’t be considered smart or sophisticated; she would just be another boring person. New money and old money represents the way in which people are criticized, judged or understood. Old money has a tendency to seclude themselves from lower classes but do not discriminate. While new money tends to show off their wealth to the lower classes by throwing spectacular parties and get togethers. A new money party is portrayed as if it were the time of your and a night that no one will ever forget. The author says, â€Å"The groups change more swiftly, well with new arrivals†¦confident girls who weave here and there among the stouter and more stable†¦excited with triumph, glide on through the sea-change of faces and voices and color under the constantly changing light† (page 40-41). New money parties are exciting and extravagant but the only reason these parties exist is because people with new money become selfish and proud. They pride themselves on where their wealth has brought them. Newly acquired wealth causes people to change, to become someone they really aren’t, and to do things or be with people they normally would spend time with. An old money party is more like a get together. People must be invited and old old money is expected. The author explains, â€Å"People disappeared, reappeared, made plans to go somewhere and then lost each other, searched for each other found each other a few feet away† (page 37). The author describes the old money parties in a relaxing manor because parties are not new to people who have had money all their lives. It is not difficult to see the importance that money played not only in the novel, but apparently in the 1920’s. The author crafted each character around their social station in life, which was determined by where their money came from. It was apparent that despite the fact that Jay Gatsby worked and earned his money, that it didn’t change the fact that he was from the â€Å"wrong side of the tracks†. And while being from the â€Å"right† side of those same tracks, having money didn’t really give Daisy what she wanted or needed to be happy. In the end, Gatsby died a lonely death, remembered by few.

Comparing Composed Upon Westminster Bridge by William Wordsworth and Lo

Comparison between William Blake and William Wordsworth’s Views of London William Blake grew up in the slums of London and this is shown in his poem, he wrote his poem in the slums and back alleys of London as he never had very much money. He describes London as being â€Å"charter’d†, this gives us the impression that everything has rules and boundaries in London, and that there is no mystery to be discovered. Also chartered means on a map, almost as if it is owned, by the king perhaps. The line in which the word is on, â€Å"I wander through each charter’d street, near where the charter’d Thames does flow,† makes us feel as if every thing is owned and nothing is natural, like all the people in London are prisoners of society The ending line of stanza two tells us, â€Å"The mind-forg'd manacles I hear†, this is Blake’s way of showing to us that there are no free minds in London. Everyone had been brainwashed by society and they could not think for themselves because of that. In the next stanza Blake describes the corruption of the Church of England by mentioning, â€Å"Every black'ning Church apalls† this shows the dirtiness of the buildings and shows us that there is a possibility that he is a strong catholic. This line ties in very well with the line directly above it â€Å"How the chimney-sweeper's cry†, both of the lines are discussing how dirty and filthy London is. We could also think of these lines in a different way Blake could be telling us that the priests are corrupt and dirty rather than just physically dirty. In the final line of this stanza, Blake states. â€Å"And the hapless soldier's sigh, runs in blood down palace-walls.† This could be considered as an other sign of corruption, and that monarchs are to blame for the death in London a... ...f London, but they only do this because of their life before they wrote the poems. One poet grew up in the rich area outside London and moved there later, whereas the other poet grew up in the slums of London. They never had the chance to see London through each others eyes, if they had they may have thought differently of London. Both poets grew up and wrote about what each thought of the same place, London is a city that is magnificent and beautiful to the people who know it like that. Whereas it is filthy and dirty to the people who have grown up in those filthy dirty areas. In my opinion London is a place that is somewhere between these two extreme versions of it, a place where there is magnificent splendour but also a place where there is filth and poverty. Theses poems where written two hundred and six years ago and London has not changed that much since then.
