Förebyggande effekter av fysisk aktivitet på depression : ? en litteraturstudie
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.
Vår Kokbok : En studie om den historiska utvecklingen inom matkonsumtion i Vår Kokbok
Swedish consumption habits led to a discourse on consumption needs of the general public during the first half of the 20th century, involving primarily several institutions, but also a variety of popular movement organizations, among which we find Kooperativa Förbundet. In this discourse, ascetic consumption and a rationalized outlook on consumption were idealized, as the Swedes needed to be economical not to live beyond their means. The objective of this study is to investigate the ideals this type of discourse conveys throughout the latter half of the 20th century. This will be achieved by investigating selected editions of the cookbook ?Vår Kokbok? published by Kooperativa Förbundet.

Overall Equipment Effectiveness (OEE) : Problem och framgångsfaktorer vid mätning av utrustnings effektivitet med OEE i små företag
En hård konkurrens bland dagens produktionsföretag på en global marknad ställer kravpå dessa att vara effektiva i sina processer för att överleva. Särskilt små företag, sominte har ett stort företags ekonomiska muskler och möjlighet att investera i nyutrustning, måste vara innovativa och kunna utnyttja befintliga resurser maximalt.Overall Equipment Effectiveness (OEE) är ett nyckeltal som mäter ett företagsutrustningseffektivitet. Genom att använda OEE kan ett företag uppmärksamma var detfinns förluster i produktionsprocesserna och därefter åtgärda dessa.Den här rapporten ämnar reda ut i vilken utsträckning små verkstadsföretag i Sverigeanvänder OEE idag. Teorin pekar på att stora effektivitetsförbättringar är möjligagenom användning av OEE i stora företag, dock finns endast lite litteratur sombeskriver användningen av OEE i mindre företag. Syftet med rapporten är därför att tareda på vilken potential det finns för små företag att använda sig av nyckeltalet OEE samt att identifiera specifika framgångsfaktorer för dessa.Genom intervjuer med små verkstadsföretag och konsulter väl insatta i OEE, harproblem och framgångsfaktorer identifierats.

Den demokratiska konsolideringen i delade samhällen - fallet Makedonien En studie om Makedoniens demokratiska utveckling efter den väpnade konflikten år 2001
The consociational democracy model in Macedonia, which came out from a warcrisis and a peace agreement from 2001, in addition, putting an end to the violent conflict, actually admits the division of the society along the ethnic lines. Paradoxically, there is an attempt to bridge the ethnic gap with this model. As a result, the consociational democracy model holds solutions that can be abused if somebody misuses its power and desires to disintegrate the country. The future development depends therefore on the moderate attitude of the citizens, and first and foremost, on the political elites and their commitment to the values of democracy and human rights instead of their nationalistic goals. Furthermore, thepresent democratic consolidation in Macedonia is established on the execution of the peace agreement and the improved effectiveness of the institutions.
En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet
The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.
Effektiv prestationsmätning : en studie av prestationsmätning i kund-leverantörsrelationer
Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.
