Objective: To study the evidence on physical activity (PA) as an effective preventive strategy for depression.Methods: A search of electronic databases was performed for articles between 2007 and 2012, both original research and review articles, concerning the link between PA and depression on children, youth and adults. Three reviews, five longitudinal and two cross sectional studies were included.Results:  PA reduced the likelihood of depression in many studies and a sedentary or inactive lifestyle increased the risks for mental health symptoms such as depression. One study showed that low PA in childhood increased the odds of depression as an adult and other studies on teenagers saw a connection and mediation between PA and self-esteem whereas physical fitness showed no mediating effect. Many of the studies and reviews point out the insecurity regarding the dose-response association and the difficulties in defining causality.Conclusion: PA might have a preventive effect on depression. Some evidence exist to support that PA in childhood prevents depression in adults.

This thesis aims to study the indirect effects of the Europeanization on national parties and the presence of an established national opposition towards the European Union (EU) and its effects in Sweden, as a result of the so-called conflict of Vaxholm. The questions asked were whether or not it existed an established national opposition towards the EU, and if so, what the opposition consists of substantially. The research method, which was used, is a quantified text analysis on the chamber debates of the Swedish Riksdag and the party congresses of Socialdemokraterna. The study shows that there is an ambivalent opposition towards the EU and its effects in the aftermath of the conflict of Vaxholm.  Socialdemokraterna presented resistance, but did not manage to present apparent alternatives, which left the party with a rather indistinctive opposition. In contrast to the right-wing party, the left-wing party had some profound difficulties in positioning itself in the new and globalized economy. I therefore suggest, that it might be more providing and exhaustive to introduce Azmanova?s ideal-type analysis, which instead of positing parties on a left-right continuum, posit parties after respective party?s opinions concerning the risks or opportunities which the EU and the internal market?s effects. .

AbstractThe aim of this study was to find out how patients with type-2 diabetes reflected on self-care and the information about selfcareactivites regarding diabetic footulcers.The study has a descriptive design with a qualitative approach. The study included fourteen patients with type-2 diabetes and they had footulcers related to their disease. They were recruited from different health centres in two cities in the Middle Sweden. The patients were interviewed and the interviewes were transcribed and worked up with qualitative content analysis. The authors recived seven subcategories which were sorted into two categories; reflection regarding information about self-care and reflection regarding self-care.

Social media, with its immense and continuous flow of information, has in recent years growntremendously in terms of users and content. This increase has led companies and organizations keen to be seen within these channels of communication, but do they always have a clear idea of how andwhy, and are they aware of the risks that are associated with it? Current research on social media is somewhat divided in two. The debate concerns, among other things, what value the information on social media has, and whether the media is really a good communication channel or not. This raises several questions, for example can a company really afford to remain outside of social media with allthe information it generates? This research aims at answering these questions in order to further understand how organizations discuss social media presence and strategies.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

This master thesis explores the nature of public participation as a central and most current subject in the field of urban planning. A first impression exposes a seemingly unanalyzed consensus on the values and benefits which public participation provides the process of urban planning. The city may be a concern to all its inhabitants; hence knowledge and opinions of the local public are of great importance for the urban development. But is there really something new to these assumptions, and are the advantages of increased public participation in urban planning always obvious?  By using action research as a main method, I have put myself into the context of the Swedish municipality of Nacka and their projects dealing with the development of public participation.

Sexually transmitted diseases among youths is a growing problem. Generally, the knowledge about sexually transmitted diseases is relatively good, however, the risktaking among youths is great. The schools education regarding sex is often insufficient. The foundation for avoiding STD is knowledge. However, knowledge does not solve the attitude problem regarding the use of condoms.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The project Easy Battery Handling - EBH has been carried out in our auspicial and completedfor Devantini Corporation, a development company in Halmstad with its main concern inenvironmental friendly innovations.EBH has solved one of many technical challenges in one of Devantini corporation?s largerprojects. This main project involves the development of an electric powered formula racingcar. The part of this car that involved EBH was the battery handling to guarantee safe andquick battery exchanges during pit-stops.The solution became an entire battery module, hanging on the side of the car on two spearspointing out from the car. The batteries are exchanged by a specially designed trolley that isinserted under the battery module.

The purpose of this study is to examine escort-business with a focus on sales of BDSM-services (Bondage and Discipline, Dominance and Submission, Sadism and Masochism). The study is based on qualitative interviews with three informants providing BDSM-services, as well as a survey with 96 men who requested domination of escorts (the survey was carried out by an escort in the 1980s). The analysis of this material resulted in the identification of three themes on which the study centers: The personal experiences of the three escorts, the interaction between the escorts and the clients, and the changes over time when it comes to the performance of BDSM-services. The study has a gender perspective with a focus on feminism and queer-theory. The important conclusions are that there are several differences between prostitution having a focus on BDSM-services and other prostitution.

At the moment, democracy enhancing projects can be seen everywhere on the municipal level. The purpose of this thesis is to explain how the city of Lund takes on this challenge, why they have chosen to carry out citizen councils and if these are a good way to intensify democracy and open communication channels between citizens, the administration and the elected officials.The theoretical framework consists of seven arguments for gaining citizen influence on policy, and as a counterweight three critical arguments that opponents of participatory democracy often use are added.After a survey over both the Swedish national trends in municipal renewal and the last years work in Lund, the analysis goes on showing that most of the arguments point to the disadvantage of the citizen councils. Even though legitimacy possibly is enhanced by the project, there are probably better ways to open up for more communication and intensify democracy in the local community..

The purpose of the essay is to investigate whether the principles formulated by Peter Ackerman and Christopher Kruegler, concerning strategic non-violent conflicts, can serve a purpose when analyzing improvised non-violent conflicts. The principles are derived from factors that have been prominent in earlier successful improvised non-violent conflicts.The essay is based on two research questions; if the factors included in the principles formulated by Ackerman and Kruegler, exist in the two cases that this study investigates, and if those principles offer a satisfactory explanation for the outcome of an improvised non-violent conflict.To answer the questions the study uses a comparative method, where the improvised non-violent conflict of 2004 in Ukraine is compared to the improvised non-violent conflict of 1988 in Burma.The answer to the first question shows that the factors contained in the principles previously mentioned, exists in both cases. The answer to the second question is more uncertain, as there seems to be doubts on whether the case of Ukraine really was completely improvised. Another reason for caution is that the factors contained in the principles, only consider actions made by non-violent actors, and not by opponents or third parties. Thus the risks of missing vital explanatory factors are substantial..
