The aim of this thesis is to clarify the affect that preferential and regional trade agreements have on the World Trade Organization (WTO), as being establisher of the international trading regime. The essay is an explanatory literature study, which strives to answer the following questions:Are regional and preferential trade agreements a threat or a complement to the WTO?Is an undermining of the MFN principle weakening the WTO?How do regional trade agreements made by the EU affect the future of the WTO?The empirical material is to be analyzed using an explanatory framework, which is based on neo-liberal instutionalism, theories on regime changes and a game theoretical approach, using prisoner?s dilemma. I will employ the EU-ACP relation, the Cotonou agreement to exemplify how an agreement of this kind can have an influence on multilateral trade. The result shows that preferential agreements do have an impact on the WTO, one that is fairly negative in scope.

En stor del av jordbrukets växthusgasutsläpp kommer från nötköttssektorn. Dess produktion påverkas i Sverige och EU av EU:s jordbrukspolitik. En större del av jordbrukssubventionerna var tidigare kopplade till produtionen vilket gav incitament att öka produktionen. 2003 infördes en reform med gårdsstöd som var frikopplat från produktionen. I uppsatsen studeras litteraturen kring hur nötköttsproduktionen påverkas av gårdsstödet, och utifrån detta görs egna beräkningar om förändringar i växthusgasutsläpp.

Investigations concerning adolescent mental health shows a negative development. Many pre-vious studies have focused on young women's mental health. Therefore, the aim of this study was to investigate young men's (17-19 years) experience of their mental health. Qualitative interviews were used as a method. The participants were six young men who all go to high school in a major municipality in the county of Gävleborg.

Tidiga vuxenlivet präglas av oprövade miljöer och situationer. Detta ställer höga krav på individens perception, anpassningsförmåga och attityd. En intensiv miljö flertalet unga vuxna kommer i kontakt med för första gången är krogen. Positiv attityd till riskfyllda beteenden där kan i förlängningen resultera i negativa hälsoeffekter. Syftet med denna enkätstudie var i huvudsak att undersöka unga vuxnas attityd till Verbal aggression, Rekreationellt berusningsdrickande, Riskfyllt sex, Fysisk aggression, Ekonomiskt riskfylld modekonsumtion, Ekonomiskt riskfylld festkonsumtion, Rekreationellt drogbruk och Riskfyllt spelande om pengar.

Sound surrounds us in a great extent, we all have experiences of sound and this phenomena has a great meaning in our lives. High levels of sound might be harmful for your hearing and might also cause related difficulties such as tinnitus and sensitivity to sound. Studies reveal a connection between the attitudes toward high levels of sound and the risk behaviours in these situations. The purpose of this study was to explore the experiences and meaning of sound and whether the attitudes toward sound will reflect in a family consisting parents and adolescents. A family consisting two parents and two adolescents participated each and one of them in an interview in this qualitative study that has been carried out of a phenomenological approach.

Pain related behaviour in 1.5 year old colts was studied both prior to and following castration. The horses were filmed 24 h prior to surgery and 24 h postoperatively. Parameters, inactive and active behaviours, were recorded in terms of cumulative time observed. Both groups of horses were exercised three times and the gait quality was evaluated. Few differences were observed between the groups.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Universitetsstudenter har ofta ett riskabelt alkoholbeteende ochupplever depressiva symtom under studietiden, vilket kan ha svårakonsekvenser. Förklaringarna till alkoholkonsumtion blanduniversitetsstudenter har ofta fokuserat på studenters motivation tillsocialisering med andra studenter. Litteraturen har också fokuserat påförstaårsstudenters övergångsfas i förklaringarna till depression.Denna studie involverade 117 universitetsstudenter i ett medelstortsvenskt universitet. Studiens huvudsyfte var att undersöka omstudenter som bytte ort för att studera dricker mer alkohol ochupplever flera depressiva symtom än studenter som studerar i sinhemort. Resultatet visar på en betydande skillnad i alkoholkonsumtionmellan de två grupperna, vilket tyder på ett samband mellan flyttenfrån hemorten och alkoholkonsumtion..

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.

The purpose of this study is to describe and analyze homelessness in a medium-sized municipality from an organizational perspective. Some of the central questions in this study are: How is the cause of homelessness explained? How do different actors in the community address, prevent and combat homelessness? Who is responsible for the homelessness?This study is based on four semi-structured interviews with organizations that work with homelessness. The analysis is based on problem definition theory.The result of this study shows that homelessness is a problem in this medium-sized municipality even if it is not a big one and that it is often closely combined with substance abuse. The responsibility for the homeless is on the homeless themselves and the social service because that causes is, according to this study, individual based.  .

This report is based on factors that has had affect on drugaddicts in their decission on quitting their abuse. The questions we have built our report on are: What external factors have had an impact on the drugabuser to end his or her drugabuse? What internal factors have had an impact on the drugabuser to end his or her drugabuse? Does the police have an influence on the drugabuser to end his or her drugabuse? The report is based on intervjues with former drugaddicts. We have also studied the theory of symbolic interactionism and litterature written by different authors to obtain a broad picture of drugabuse. Our results in this report show that the people we have intervjued have been influenced by many different factors and people in their enviroment.

During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003. Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.

Studenter är bland de som konsumerar mest alkohol i Sverige. Hög alkoholkonsumtion och extern akademisk locus of control (ALC) har liknande negativ effekter på studier. Denna studie undersökte relationen mellan alkoholkonsumtion, ALC och alkoholrelaterade studieproblem. 120 studenter, varav 91 var kvinnor, deltog genom att besvara en enkät bestående av The Academic Locus of Control Scale for College Students, the AUDIT Alcohol Consumption Questions och en egenkonstruerad skala som mätte alkoholrelaterade studieproblem. Data analyserades med en 2 (riskbruk/ickeriskbruk) x 2 (extern ALC/intern ALC) ANOVA för oberoende mätningar.
