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.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

My essay is an examination of the poet Mina Loy and two poems that are essential in her authorship, these poems also represents a thematic entrance to Loys life and literary concepts. On the basis of Gunnar Harding preface and translation of selected poems from the collection Lunar Baedeker, I have chosen to look further at the poems Lunar Baedeker and Songs to Joanne, poems that accommodate contexts of an esthetical and linguistic complexion.Using terminology from the philosopher Gilles Deleuze as method for analysis, enabling an examination which proceeds from the concepts of nomadism, deterritorialization and line of flight. In the consideration of Loys modernistic and woman ?becoming, a situational and relational context is introduced which includes references to feminism, cosmopolitism, futurism, modernism, Dadaism as well as to acquaintances of Gertrude Stein, Djuna Barnes, F.T. Marinetti and Isadora Duncan.

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

This study deals with the Swedish public library in our changeable time. New technology, an altered media situation with a growing digitalization, globalization and a society focusing on the individual and the market have put the public library in a new, indistinct position. It is described as facing an identity crisis. The aim of this thesis is to, by interviewing a group of young people ages 15-16, find out what the public library is for this user group and what it ought to be according to them. How do they value the services provided by the public library? Are there services they miss? The thesis also aims at relating the opinions of the young people to earlier research.

Sustainable design - a study on sustainable design and its incentives and barriersThe purpose of this study was to investigate the incentives and barriers existing within companies focusing on eco-design. The aim was also to examine the consumers? thoughts on eco-design and sustainable products. A further aim was to try to concretize important lessons for future work on sustainable production and consumption. Two methods were used for completing this study; a literature study and a practical study consisting of interviews with companies focusing on eco-design and a survey among students.

Med utgångspunkt i George Lakoff och Mark Johnsons teori om den konceptuella metaforen analyseras i denna uppsats bildspråket i opionsjournalistiska texter som behandlar frågan om individualiserad föräldraförsäkring. Därtill anläggs med hjälp av Yvonne Hirdmans teori om genussystemet ett genuserspektiv, för att undersöka om metaforerna är könade och/eller reproducerar det binära könstänkandet. Materialet är hämtat från DN, Aftonbladet, Expressen och SvD under perioden januari 2010-novmeber 2013. .

Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.

This study explores how consumers' attitudes and intentions-to-buy towards an atypical product can be influenced by the presentation of the product and consumers shopping goals. Moreover, another product, which was shown together with the atypical piece, was analyzed in order to investigate context effects. The aim of the study is to provide insights into a rather unexplored subject and help retailers in presenting their assortment in a way which will create a better perception and intention-to-buy towards the assortment. The study was conducted with the help of two studies, the first one aimed to find an atypical item and to see how attitudes could be affected by differences in presentation by comparing it with a typical item within the same category. The second study used the identified atypical piece in order to see the how attitude and intention-to-buy could be altered by presentation and consumer shopping goals.

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

The aim has been to see if physical education (PE) is more an arena for bullying than swedish language education, in a swedish urban school. Furthermore to get an insight in the students sense of exposure to bullying in the locker room and during PE class. In the purpose is also included to analyse the answers in a gender perspective.Questions are: Is PE to wider extent an arena for bullying compared to swedish language education? Is the students? opinion that they feel worried about being and changing clothes in the locker room due to other students bad intentions? Do the students think that boys and girls bully in different ways?The method used is a questionnaire answered by 69 students in seventh and eighth grade in Åsö compulsory school. Furthermore, interviews has been made with a boy, a girl at the school and a teacher in PE to get a deeper insight above the questionnaire.Results of the study showed that the students to a wide extent, 100 % of the girls (g) and 89 % of the boys (b) thought that bullying can look different between PE and swedish language class.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

Since 1987 until November 2010, the entrepreneurs who choose to conduct its? company in the Swedish corporate form aktiebolag had no opportunity to evade or deselect the mandatory audit. The only choice that really was there to make was to which audit firm they would turn to and the Swedish auditor?s position was rather unchallenged. Today the circumstances are different and the small businesses have been given a chance to take charge of their own situation now being able to remove the auditor.

Taiwan has over the past thirty years experienced a substantial political transformation. Being ruled by Chinese nationalists since World War II, Taiwan started its democratic transition in the late eighties. The new democratic system did not only provide people with freedom to vote, it also marked the beginning of a search for a new national identity. Based on the international theory of constructivism, this paper defines and studies the Taiwanese people?s progression away from a dominant Chinese national identity towards a uniquely defined Taiwanese identity.

-1949 [26][upps-01.gif] The aim of this master thesis is to investigate how W.E.A. Workers Educational Association, took part in the great changes of society and in the modernizing process in the period of 1920-1949. The examination is based upon three journals of educational material that were connected with W.E.A. The question at issue is to show how the people behind W.E.A. aimed to educate and indeed educated the workers to modern people and moreso to see how the articles in fact were written and to analyse in what way they turn to the workers and get their attention.
