Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.

To log on to social media has become an obvious part of people's everyday routine. Pictures, videos, opinions, and thoughts are posted and read by people's social networks worldwide. In doing so, the present study chose to examine whether what is posted on social media, as well as what the individuals are exposed to on social media can be related to their motivation and self-esteem. By letting 117 adolescents aged 16-19 answer a questionnaire regarding which social media they are active on, how often they are active there, and what they post on those social medias. By also letting them evaluate how they see themselves, if they compare themselves with others and how motivated they are to physical activity and healthy eating habits, we could see that to those who post pictures, and are exposed to images represent exercise / health on social media have higher self-esteem and driven more by internal motivation to engage physical activity than those who do not.

Offentlighetsprincipen ger svenska medborgare rätt att ta del av de allmänna handlingar som finns på våra myndigheter. Rätten till insyn är av stor vikt och en hörnsten i vårt folkstyrda samhälle. I samband med den moderna teknikens utveckling har allt fler traditionella pappershandlingar ersatts av elektroniska. Även här är offentlighetsprincipen tillämpbar, men detta verkar inte alla vara medvetna om. Idag finns stora brister i e- posthanteringen vilket leder till en försvagad möjlighet till insyn.

Det finns mycket tidigare forskning kring könsrepresentation i media, dock är det inte alla medie-genrer som uppmärksammas och mode har ofta en marginaliserad roll i genusforskning. I denna uppsats undersöks hur den franska modetidningen Vogue Paris representerar ?la Parisienne? ? den parisiska kvinnan ? utifrån de två motsägande vetenskapsteorierna feminism och post-feminism. Syftet med denna uppsats är att bidra till den feministiska debatten kring mode och könsrepresentation i media och ge ny insikt kring hur modetidningen representerar kvinnan. Genom en kvalitativ innehållsanalys av olika modefotografi ur två nutida nummer av modetidningen som representerar ?la Parisienne?, med Roland Barthes semiotiska modell som metod, besvaras frågorna: hur representerar Vogue Paris ?la Parisienne? genom modefotografi; på vilket sätt (re)konstrueras myten om ?la Parisienne?, samt vad innefattar denna myt; hur kan denna representation/konstruktion uppfattas utifrån feminism respektive post-feminism; och slutligen, hur förhåller sig denna myt till den dominerande ideologin om kvinnlighet? I min undersökning kommer jag fram till att Vogue Paris konstruerar en motsägelsefull och kontrastfylld myt om ?la Parisienne?, som innefattar en innebörd som både feminin och sexuell men även naturlig och maskulin.

Det finns idag ingen konsensus om den optimala rehabiliteringen efter en främrekorsbandsrekonstruktion, vi vet heller inte idag huruvida rehabiliteringen skaspecificeras efter parametrar som kön och ålder. Studien var en korrelerandetvärsnittsstudie med syfte att ta reda på om det förelåg någon skillnad i postoperativlårmuskelstyrka 4-7 månader efter en korsbandsrekonstruktion med avseende på kön,ålder, skada och typ av operativt ingrepp. Av de 330 aktuella försökspersonerna var detendast 74 personer som godkänt deltagande och uppfyllde kraven förinklusionskriterierna. Försökspersonerna testades i en isokinetisk dynamometer(Biodex)för maximal styrka(60gr/s) och uthållig styrka(180gr/s). Resultaten presenteradesgenom ett Limb Symmetry Index.

Syftet med denna uppsats var att undersöka hur ett projekt startas upp, leds och drivs då det är kopplat till socialt arbete och efterbehandling för hemlösa kvinnor med missbruksproblematik. Bakgrunden är en tidigare b-uppsats som visade på brister i eftervården för dessa kvinnor. Examensarbetet har gjorts genom en litteraturstudie där vi undersökt projekt och projektledning, samt en halvstrukturerad personlig intervju och en telefonintervju med en nyckelperson med erfarenhet av projektarbete. Resultatet visade på att det är viktigt med samarbete och nätverk då det oftast finns många aktörer som kan hjälpa målgruppen, så som socialtjänsten, beroendecenter samt Röda Korset. Genom ett lösningsfokuserat arbete och en upplevelsebaserad metod kan målgruppen få hjälp att komma tillbaka in i samhället och få ett självständigt och värdigare liv.

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.

AbstractThis thesis discusses and analyses a 19th century female author's vanishing from history. The study investigates social relationships as figured and described in the epistolary form, based on letters between the author herself and different members of her family. It also tries to identify the author's position and situation in her time and society according to important themes and motifs in her novels. The main purpose is not to reconstruct history, but rather to show the many complex histories that can also be described, apart from the simplified and generalized one. The aim of this study is to, from a post-structuralist perspective, analyze the position of author Marianne Lundegård-Hagberg, and her role as a performative, discursive person that history forgot..

The purpose of this master's thesis is to investigate how the students at Chalmers University of Technology at Lindholmen in Gothenburg use libraries in their schoolwork. The empirical material consists of the answers of questionnaires that were handed out to two classes of students, on the second year of their education. To illustrate the topic there are a theoretical frame and examples of earlier studies. The theoretical frame is Limbergs texts that deal with for example information seeking and how important it is in all education. The earlier studies are about student's different ways of using libraries.

The main purpose of this Master?s thesis is to investigate how the transfer from academic studies into professional life is experienced in retrospect by professional librarians. The aim is also to examine in which context the studies in library- and information science in Sweden has been formed. To attain the purpose of the thesis four main questions is being asked: In which context has LIS-studies from the period 1993-2007 been formed? Which competence does the professional librarian consider to be the most fundamental in professional life? Does the professional librarian experience that the knowledge attained from LIS-studies is sufficient for the actual tasks? Which are the differences between tasks at different types of libraries? The study is performed through a questionnaire survey in which 94 professional librarians express their experiences of their LIS-studies in retrospect.

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

This thesis deals with tactics for information seeking in electronic databases. An important aspect is knowledge of the relative value of different subject access points. The method used here is literature studies. Nineteen empirical studies are described and analysed with the purpose to compare the relative value of different subject access points. The studies examined compare the relative value of subject access points in relation to each other or in relation to different scientific disciplines.

This thesis explores the validity of feminist poststructuralist theory in relation to gender and culture. Within the theoretical frame¬work of Judith Butler, combined with insights from the field of post-colonial theory, different perspectives of the dilemma of universalism are discussed. Primary sources for the study are policy documents from the Swedish government, literary texts and newspaper articles. The results show a number of paradoxes which need to be continually and critically kept unsolved. This does not mean an end to feminist engagement in other contexts than one's own but rather the need for theoretical awareness and self reflection.

The main purpose of this examination paper has been to do a review of recent scientific and evaluated studies performed on children 0-15 years of age, treated with an animal as an assistant to the therapist/professional. The key term is Animal Assisted Therapy (AAT). Our focus has been to describe in what fields these kinds of studies have been performed, what the results are and how effective they have been. As a supplement to our study we have performed 8 short telephone interviews with professionals in the same field of occupation corresponding to the studies we have summarized. Our results concerning the studies show that there has been a positive outcome in the treatment of children and adolescents and AAT.

Projektarbete har blivit en alltmer vanlig företeelse inom moderna organisationer. Nästintill alla organisationer arbetar idag med projekt som ett komplement till den dagliga linjeverksamheten. I dagens samhälle sker förändringar allt snabbare och traditionella riktlinjer inom projektledning visar på brister i hanteringen av denna föränderliga omvärld och den osäkerhet som uppstår på grund av förändringarna. I denna uppsats har vi valt att intervjua ett urval erfarna projektledare inom IT/Telecombranschen. Detta för att utreda hur en föränderlig omvärld och osäkerhet påverkar planering, som traditionellt sker genom att bryta ner projektet i olika faser.
