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.

The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.

During 2001-2002 a prototype, IMIS (Integrated Mobile Information System) was developed at BTH (Blekinge University of Technology) to demonstrate how mobile IT-systems can be used in healthcare. The prototype was based on the activity theory of Engeström. An ongoing project started in spring 2003. The purpose of the project is further development of IMIS with special focus in the diabetes healthcare. Participants in the project are scientists and students at BTH, ALMI Företagspartner, Blekinge FoU-enhet, Barndiabetesförbundet Blekinge, Blekinge Diabetesförening, Vårdcentralen Ronneby and Vårdcentralen Sölvesborg.

The purpose of this study was to examine the experience of organizational culture among salespeople at a specific workplace. The purpose was also to investigate what motivates these salespeople in their work and the impact culture has on their motivation. We have used a qualitative research method to collect the empirical material. With the help of seven interviews, including six salespeople from one of Sweden?s biggest electronic retailer and also one information interview with a sales consultant, we attempted to find the answer to how they perceive the organizational culture and how it affects their work motivation. The following questions are used to fulfill this purpose: ? How do the salespeople experience the organizational culture? ? What motivates the salespeople in their daily work? ? What effects does the organizational culture have on the salespersons motivation? As analytical tools we have used are the concept of organizational culture, Schein's description of the three components of culture and Herzberg Motivation-Hygiene theory. The results of the study indicate that the salespeople experience a positive organizational culture and that this culture promotes fellowship and unity between colleagues, which in turn contributes to an enhanced motivation.

Vätternrundan is an annual sporting event that takes place in the Swedish town Motala since 1966. It is one of the world largest recreational bicycle rides and attracts over 20 000 participants each year. This study focuses on event effects and how an event can be of value within the principles of place marketing. Within this study five representatives were interviewed with semi-structured interviews.The results show that the representatives describe Vätternrundan as a positive event which mostly generates positive effects for the city itself and for the people living and working there. The effects consist of the events ability to create awareness of the place, the possibility to extend the tourism season and several social effects like solidarity and interaction.The result also shows that Vätternrundan is a well-known brand and because of this it can be used as an advantage in place marketing.

This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

In this thesis, we are concerned with the many different professional roles that a public librarian, working at a small library, has. More specifically, the purpose is to find out which different roles that librarians believe they have, and which view they have upon those. Furthermore, we are exploring the tendencies that librarians discuss in relation to these professional roles. To pursue this goal, we have used the methodology of focus group interviews, with the unconventional twist that our interviews were done using web chats. This may have the advantage that the informants may present more honest views than when using ordinary interviews due to the anonymous character of chatting.

Within the journalistic profession lays a commonly accepted normative view stating that objectivity is an ideal to seek. The aim of this bachelor is to study Swedish sportswriters on local newspaper and their views of journalistic objectivity, and themselves in comparison to the traditional ideals. We want to study how local sportswriter work against their ideal and if factors like age and education affect their view of themselves and ther ideal.We have done eight semistructured deepinterviews that all build on theories and studies of the traditional ideal of journalists. The interviewed are all sportreporters, at four different newspapers. We have done active selection of participants based on age and education.

Ombord på moderna fartyg finns möjligheten att navigera med enbart ECDIS. ECDIS är beroende av många olika delsystem för att kunna fungera optimalt.Failure Mode and Effect Anylysis (FMEA) är ett verktyg med vilket man kan undersöka ett specifikt system för att upptäcka eventuella konstruktionsfel och brister i produktionsdesignen. Detta examensarbete har med hjälp av en FMEA undersökt ECDIS simulatorerna vid Sjöfartshögskolan i Kalmar för att ta reda på hur ECDIS påverkas när ett eller flera av delsystemen kopplade till ECDIS fallerar. Syftet med denna undersökning har varit att upptäcka konstruktionsfel, brister och begränsningar i ECDIS systemet vid simulatorerna i Sjöfartshögskolan i Kalmar. Det kunde påvisas att ECDIS i vissa fall ej har avgett de larm som enligt tillverkaren skall varsko navigatören att ett delsystem har fallerat.

CSR är viktigare än någonsin i dagens ekonomi och konceptet är numera etablerat i de flesta branscher. Huruvida det finns ett samband mellan CSR och intäkter är omdiskuterat. CSR inom underhållningsbranschen har dock inte fått någon större uppmärksamhet i akademiska sammanhang. Syftet med studien är att undersöka om, och hur, CSR kan användas som ett strategiskt verktyg i jakten på sponsorer. Ett positivt samband skulle kunna uppmuntra socialt ansvarstagande i branschen.Uppsatsen består av en kvalitativ fallstudie av Hammarby Fotboll.

Detta examensarbete omfattar 15 hp och utfördes av Jelena Todorovic, student på Malmö Högskola, Produktdesignprogrammet. Syftet med arbetet var att utveckla en sportbag för personer som bor i närheten av ett gym och som efter träningen duschar hemma. Projektets bas var Användarcentrerad design, som innebär att utvecklingen av konceptet sker efter användarens behov, önskemål och preferenser. Användaren inkluderades i projektet i allt från skisser, intervjuer, observationer, utvärderingar och urval av koncept till slutkonceptet. Studenten såg ett behov av en annan väska än den traditionella sportbagen. Projektets förstudie resulterade i att studenten sammanställde en kravlista på målgruppens önskemål och behov. En sportbag där funktionaliteten var viktigast kom att bli projektets fokus.

Denna studie gör en inventering av de argument som attraherar värdnationer till att ansöka om värdskap för megaevenemang. De megaevenamang som behandlas i uppsatsen är fotbolls-VM i Tyskland 2006 och fotbolls-VM i Sydafrika 2010. ?De ekonomiska framgångar som antas för värdnationerna visar sig oftast vara felaktiga då kostnaderna underskattats och intäkterna överskattats. Att vara värd för så stora megaevenemang kräver stora förpliktelser från både offentliga och privata resurser under en lång tidsperiod. Ett värdskap för fotbolls-VM kan ge värdnationen de resurser de behöver för att skapa ett meningsfullt socialt liv och att förändra faktorer som underbygger detta.

In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.

Imagery is an individual and cognitive process (Morris, Spittle, & Watt, 2005). This study has therefore qualitatively examined following objectives: (1) elite powerlifters imagery experiences and (2) if elite powerlifters use imagery deliberately. Five elite powerlifters participated in the study (3 men, 2 women), they were 21-37 years old (M = 27.6; SD = 6.1). The Individual Profile of Imagery Experiences in Sport (IPIES; Weibull, 2008b) was modified and used to meet the objectives for the study. Imagery was used by all elite powerlifters.

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.
