Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek
The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.
Skrylleområdet - naturupplevelse som motivation till motion? :
Our lives in urban areas are becoming more and more inactive with negative effects on our
mental and physical health. Natural environments and physical activity have the power to
both prevent and reduce mental fatigue. Meanwhile we engage ourselves with physical
activity, the nature fascinates us with its complexity.
In April 2006, some of the visitors to the recreational area of Skrylle were asked to fill in a questionnaire which included questions about their habits within physical activity and the experience of nature. The questionnaires were then divided into two groups: those filled out by persons who exercise on regular basis (i.e. three or several times/week) and those who rarely exercise.
Hur episodisk hypoxi p?verkar blodtrycket hos friska ?ldre individer
Aim and Hypotheses The aim of the study was to investigate how episodic hypoxia affects resting blood pressure and the acute blood pressure response in healthy older adults. The following hypotheses were formulated for analysis in the study: Blood pressure increases acutely in healthy older adults during exposure to 150 minutes of hypoxia with SpO? 80%. Resting blood pressure decreases in healthy older adults after 15 repeated exposures of 150 minutes of hypoxia with SpO? 80% over a period of three to four weeks.
Molecular testing of raspberry plants infected with tomato black ring virus
Nematode-transmitted plant viruses (such as nepoviruses) cause great economically losses in commercially important plants such as tomatoes, grapevines and raspberries all over the world. To avoid spread of the viruses the interest in mapping the viruses has increased. One of the important nepoviruses infecting European red raspberries (Rubus idaeus) is Tomato black ring virus (TBRV). TBRV has earlier been confirmed in raspberry samples from Belarus by ELISA and the aim of this bachelor degree project was to confirm these results by amplifying, cloning and sequencing the coat protein (CP) gene of the virus. In total eight viral cDNA samples, from two different raspberry samples, were amplified and sequenced.
Tvåspråkiga elever : Läs- och skrivinlärning i det svenska språket
AbstractThe phonics is traditionally firmly established within reading acquisition in Swedish schools. The curriculum, Lpo 94 gives spacious independence regarding the question of method and we have to be aware of our own point of view when we are making the decision regarding the method of reading acquisition. Is it tradition or is it our linguistic point of view that is the determining factor? Through this study of literature, different publications from different times are being studied and the ideas and the linguistic point of view are being discussed. Through comparing between the curriculums that have been replaced of one another, and attending to linguistic discussion and research, we will be able to see a change in the linguistic point of view.
Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag
The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.
Marknadsföring av bibliotek via sociala medier ? Hur ser bibliotekarier på det?
The aim of this thesis is to investigate how librarians view marketing of the library using social media and how this can be used in a marketing strategy. The theoretical framework for this thesis is based on the 7 Ps of the marketing mix, SWOT-analysis and SWOT/TOWS Matrix. The theory is based on planned elements that make up a product or service offered the market. We have used our own interpretation of the theories to analyse our material. Our main method has been a web-based questionnaire, the questionnaire was sent to 523 librarians active at ten large public libraries and its related branches.
Sänkta sjöars inverkan på ytvatten i Västerbottens kustland : Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar
Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.
Fonologisk medvetenhet i förskoleklass : En interventionsstudie
International studies show that literacy skills have deteriorated among Swedish students. Empirical evidence states that before being able to learn to read it is important to have phonological awareness. From this perspective, an intervention study was launched to examine whether pupils´ phonological awareness could be enhanced through the work of a special model during a limited time. The aim of the study is to investigate whether six pupils in preschool develop phonological awareness based on Bornholmsmodellen during a limited period of time. The control group was made up of the remaining pupils in the preschool class.
På väg mot den inre marknaden? - en studie om sammanlänkningar mellan börserna i det nya EU
Det primära syftet med uppsatsen är att studera relationerna mellan de nya och de etablerade börsmarknaderna i EU för att se om det ha skett någon förändring under perioden 1996-2005. Ett sekundärt syfte är att undersöka huruvida den finansiella integrationen inom unionen har blivit starkare under den studerade tidsperioden. I syfte att kunna besvara de frågor som vi är intresserade av använder vi oss av VAR-metoden. Med hjälp av "impulse response" beräknade vi hur snabbt en händelse sprider sig mellan de undersökta börsmarknaderna samt hur lång tid det tar innan dessa åter är i jämvikt. "Variance decomposition" talar om för oss i vilken utsträckning de olika börsmarknaderna påverkar varandra.

Both authorities and nonprofit organizations are working actively to strengthen women?s position in the labor market through incentives and other measures. The study shows that the work with exposed women takes place in cooperation between the parties involved. The purpose of this qualitative study was to look into how the professionals were working with exposed women, in different types of organizations.
Självkänsla i förskoleåldern : En studie av förskolepedagogers arbete med barns självkänsla
I denna uppsats har jag valt att studera självstärkande inslag i förskoleverksamhetens vardag och knyta an dessa till teoretiker som Erikson, Maslow samt Sommer. Undersökningen är baserad på tidigare forskning, ovan nämnda teoretiker samt en enkätundersökning. Enkätundersökningen genomfördes på en förskola med 16 pedagoger och kan därför ses som en grund för ett vidare forskningsarbete. Studien visade att det vanligaste sättet att stärka barnens självkänsla var att låta dem försöka själva innan de fick hjälp av någon vuxen, uppmuntra dem att försöka på nytt samt att ge positiv respons när de lyckades. Jag fann av svaren flest anknytningar till Maslow samt Sommer, endast några inslag kunde knytas till Erikson.In this examination I?ve chosen to look at educationalists work procedures around children?s self-esteem and how to connect those procedures with theorists as Erikson, Maslow and Sommer.
Profileringsarbete för jämställdhet inom IT-organisationer
During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.
Modernistiska och postmodernistiska aspekter av konst i offentlig miljö : En komparativ studie
This essay is about a debate concerning the magazine Axess, feminism and antifeminism - in relation to a issue of Axess called To a new feminism. The theoretical foundation of this essay is Pierre Bourdieu and his field theories. The battles taking place in this particular field concerns the positioning of feminism and antifeminism in the way we culturally interpret these in our society. The essay shows that the magazine Axess (at least in the first edition of 2012) links feminism with a very prominent symbolic capital in a culture context. This discussion can at times seem confusing, and this is probably due to the fact that Bourdieus symbolic capital can be a very abstract concept. The journalist and author Maria Sveland writes about the development of a culture moving towards accepting antifeminism (and also xenophobia). She expresses the opinion that this, to a high degree, is due to actors in the culture domain with a big amount of trust in the public eye has moved towards expressing anti-feministic (and xenophobic) views.
