The purpose of this study has been to examine how the image of the gambler is described by studying a report published by Folkhälsoinstituet [FHI] and a number of chosen articles from the Swedish Evening Press. Discourse theory has been used both as theory, together with social constructionism, and as a research method. The main conclusions of the study are that three different discourses can be identified: the normal gambler, the professional gambler and the problem gambler. The image of the problem gambler is described as a deviant and problematic minority characterized by loss of control, irrational thoughts and dissociative behaviour. The construction of the problem gambler fills three possible purposes for the state: As a solvable problem to handle criticism against negative consequences of gambling, as an argument to avoid competition on the market and as an individual characterized by loss of control in order to legitimize and make the construction of the normal gambler possible..

Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

The purpose with the study is to see how middle managers in communal elderly care looks at the implementation of the salutogenic way of working in their operations. And how it affects the middle managers working situation. We studied which scope of actions middle managers has in the salutogenic way of working. We had previous knowledge that the salutogenic working way is an ongoing work of development in several communes, and therefore we chose to study in a profound way how this work of development affects the middle managers working situation. To reach a deeper knowledge about how the salutogenic way of working affects the middle managers working situation we conducted a qualitative study with been seven semi-structured interviews with middle managers in different geographical communes.

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

AbstractComing to new job is not that easy, sometimes the feeling of insecurity appears. Working for recruitment agencies includes constant changes of colleagues and places of work and at the same time one has two different managers. Who does the individual turn to when problems occur and who do the employed see as his/her manager? Why do people search for work in recruitment agencies? How does it feel not having a fixed place of work or colleagues and how do the aspects of this affect the employed psychosocial work environment? This is a few questions asked when we tried to find answers on the employed feelings about his/hers psychosocial work environment in a recruitment agency. The purpose of this study was to find a deeper understanding on employees working in a recruitment agency experiences their psychosocial work environment on the basis of social support, demands and control.

In the recent years auditing scandals all around the world, deficient internal control has attracted a lot of attention. This has contributed to further requirements on insight and internal control. Those scandals have seriously damaged the auditor?s profession and contributed to a reduced trust among the public. Therefore an extensive work to recover and stringed the trust was started all around the world.

The purpose of this thesis is to examine how the competitiveness of family firms is affected by governance mechanisms. The thesis addresses four governance mechanisms: inefficient labor markets, inefficient capital markets, self control and altruism. We have conducted an abductive method to be able to perform a qualitative research study. In this study two family firms have been examined, ROL and Indiska Magasinet. We conclude that the presence of inefficient labor and capital markets within the studied family firms give rise to negative effects in terms of difficulties of hiring talented employees.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

This study, a document analysis with a qualitative approach, explores children, under 18years, who have been subject to measures of child welfare in the city of Malmö during theyears 1935-1937. It also explores the school's role in this context. The questions that the studyis guided by is: How was children described in the Child Welfare documents in Malmö duringthe years 1935-1937? And what role did the school have in Child Welfare work and whatmotivated this? The theoretical approaches are Foucaults theories of power, control anddisciplining.It appears from the study that the school and child welfare authorities had a close cooperationwith the purpose to control the upbringing and disciplining of the children. It was through theupbringing that the deviant child would become a "normal", docile and good, industriouscitizen.

Genom kvantitativ såväl som kvalitativ metodteori utvärdera om ett belöningssystem fungerar som ett styrinstrument..

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Abstract One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs. Newly established poultry industries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.
