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.

International conventions signifies international trade, which in itself would be ineffective if there were no dispute settlement Mechanisms. This essay intends to examine how dispute settlement Mechanisms between states have developed over the years and a large emphasis is placed on the World Trade Organizations (WTO) Dispute Settlement Body since it?s had great significance for the efficiency of international law. In order to show the need for dispute settlement Mechanisms, a background to the conventions that have called for the development of the DSB is in order. This essay focuses on Intellectual Property Rights (IPR), and the agreement that currently regulate intellectual property rights, Trade Related Aspects of Intellectual Property Rights (TRIPS), but also its connection to the DSB.

Most scientists believe that in the good times the peasant had the opportunity to follow fashion. Virestad parish does not follow fashion. My purpose is to try to understand something of the Mechanism that made Virestad do so: that I will do by analyzing the results in relation to the concept of status. My main source is estate inventories. Here I examine the status markers and differences in what they invested in clothes and jewelry in relation to the estate's proceeds.The lower the balance, the more percentage they need to put on clothes.

The aim of the study is to investigate conflicts in working lifefrom an individual and a relational perspective, as well as to illustrate how a conflict ishandled as part of a work organisation and a working environment.When a person experiences a conflict at work what do these experiences involve and how dothey affect the well-being of the person involved and the picture he or she has of him orherself?How does a workplace conflict develop over time and how can we understand its origin andcourse?How do individuals experience the way a conflict is handled in a workplace in relation to thestructure of the organisation and leadership?The study is based on a qualitative interview method with threeindividuals who have experienced workplace conflict. Through our study we endeavoured tofind an in-depth understanding conveyed through the life world perspective of theinterviewees, which is our empirical data. The analysis is related to the study?s background ofearlier research and theory within the field of workplace conflict.On the basis of our study can we illustrate that in order to prevent and handleworkplace conflict, clear communication and individual resources are required; these include:a reflexive ability to work out issues independently.

Milk and milk consumption has been subject of discussion for a long time, and is still a hot topic. Recently, as study was published that observed a correlation between milk intake and increased risk of fractures and mortality. The authors proposed the milk?s content of D-galactose as the possible Mechanism, since D-galactose is used indicated ageing in animal models. Therefore, this study aims to develop a method to determine the amount of galactose, glucose and lactose in milk and fermented milk and apply it on to dairy products on the Swedish market.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.

Background: A great part of all projects within Swedish industry are conducted in a multiprojectenvironment, which means that several projects are performed simultaneously. The research within the field of project management is though focused on single projects. Projects are highly dependent on the context in which they are conducted, although the organization of the multiprojectenvironment is only partly explored. Furthermore is the research within the project management highly concentrated on standardization of the project work. The question is whether this implies to the basic advantages with the project-oriented organization, which is flexibility and creativity? Purpose: To describe and obtain an understanding for the multiprojectenvironment regarding management control and organization.

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible Mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these Mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

An organism that is transferred from one place to another, causing major problems to the native species is termed invasive. Its natural dispersal across barriers may have been prevented but as man has turned able to rapidly travel all over the world organisms are brought to sites where they were never before observed. Adding the increasing global warming organisms may find it necessary to move around even further. This might cause major disturbance to the biological diversity, and hybridization and homogenization is one of many scenarios that could disturb the native diversity. In Sweden more that 2/3 of all alien plant species have been introduced to disturbed areas and the major introduction Mechanism is gardening.

The overarching goal of this paper is to explain the intensive occurrence of partnerships ? regarded as a specific organizational structure ? in the formulation and implementation of Regional Growth Programs.By using theoretical concepts from new institutionalism, the paper tries to examine the explanatory capacity of this theory in the specific case of partnerships. The basis is a skeptical stance towards the conventional interpretation that views partnerships as rational organizational tools. Hence, the purpose of the paper is also to compare our own institutional explanation with the conventional.The paper finds that the occurrence of partnerships can be understood as the effect of an intensive institutional pressure. The government has, in what we regard as the institution for regional development, prescribed the partnership as a rational solution ? a rationalized myth - to the regional growth problem.

The aim of this master?s thesis is to examine how exchange students experience looking for information in their new life situation during a semester in Prague. A further purpose is to investigate what barriers they have faced and how this affected their information behavior.

The interviewees are from six different European countries, were all participating in the Erasmus program, and all had social sciences/humanities/art as their main subject.

Cats and dogs are often unattended by their owners both indoors and outdoors, and therefore there is always a risk that they will get hurt. In the past, poisoning cases was considered unusual, but nowadays they are considered more common. As a veterinary nurse, it is important to know the common symptoms of poisoning, especially when working with emergency veterinary care. A very essential part of the profession as a veterinary nurse is to inform pet owners about the potentially dangerous substances and how poisonings can be prevented. The purpose of this report was to find out what is written scientifically about some common poisonings in dogs and cats and to present available statistics that covers the number of animals poisoned by various substances in Sweden. Hopefully this essay can also be used as a handbook for professionals in animal health care and to assist in educating pet owners. The report mainly covers groceries found in many homes, often easy accessible.
