Informationssökning och lärare: En studie av 4-9-lärare i övergången från utbildning till yrkespraktik
The main purpose of this Masters thesis is to contribute to the understanding of high school teachers information seeking behaviour in the transition from university studies to occupational practice. The theoretical framework encompasses theories of professional socialization, the sociology of knowledge, of professions, and of library and information science. The empirical material has been collected through interviews with six recently qualified high school teachers in different subjects. The interviews have been analysed on two different levels; first on a descriptive level and then on a theoretical level. The major findings are that the academic context limited the student teachers information seeking and they did not have the opportunity to choose cognitive authorities on their own initiative.
Konstruktion och programmering av lerduvekastare
This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.
Informationspraktik hos ensamföräldrar som genomgått assisterad befruktning

To this end, theoriesby Tom Wilson, Reijo Savolainen and Elfreda A. Chatman have been usedas a model of selection. Empirical data have been gathered from interviewswith eight single women, whose parentage has been made possible throughartificial insemination or IVF with sperm from an open or anonymousdonor.
Anorexia Nervosa - en fast identitet i en flytande modernitet? : En kvalitativ undersökning av individer som utvecklat anorexia
The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.
Användarvänlig design av bibliotekskataloger på webben.
The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.
This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.
Att leta bänkbok: bänkbokspraktiker i skolbiblioteket.
The purpose of this Master's thesis is to contribute to a betterunderstanding of children's free time reading book practices by studyingpupils in the school library and their processes of finding and borrowingbooks for themselves to read silently in the classroom, so called free timereading books. The study also includes observations of the staff's role,particularly the school librarian's in supporting pupil's book selection.The empirical material consists of field notes from an etnographic studywhere pupils in 4th grade (aged 10-11) and staff were observed duringthree school library visits. The theoretical framework is inspired byLennart Björneborn's concepts of information practices in libraries:serendipity, integrative library interface, mediation flow and affordancespaces.The study shows that pupils' search for free time reading books in theschool library is relatively routine-based at the same time as it isspontaneous. The process is an interplay with factors such as time,display and interaction in the integrative library interface. In the presenceof adults, finding books becomes an imposed task for the pupils.
Genetiska och epigenetiska samband mellan näringsförsörjning och fertilitet hos mjölkkor
The dairy cow?s ability to resume estrus after calving and to conceive is affected by their metabolic status after calving. For high yielding cows there is a high risk that the feed intake will not be sufficient to cope with the increased energy demands after calving, and the cow will end up in a state of negative energy balance. Energy balance can be measured in various ways, for example by body condition score or by plasma concentration of several metabolic hormones and metabolites. After calving, endocrine pathways stimulate tissue mobilization; insulin signaling is blocked, the concentration of insulin-like growth factor-1(IGF-1) and leptin decreases, and the concentration of growth hormone (GH) increases.
Att undervisa om nyreligiositet : En studie om högstadielärares urval, metoder och definitionsproblem
Fyra stycken lärares beskrivningar om hur de undervisar och definierar nyreligiositet och nya religiösa rörelser har studerats i föreliggande uppsats. Syftet med studien är att undersöka vad verksamma religionskunskapslärare på högstadiet säger att de undervisar om i undervisningen kring nyreligiositet och nyreligiösa rörelser. En kvalitativ metod med semistrukturerade intervjuer har använts för att få fram data till studien. Teorier om didaktiskt innehåll och undervisning som meningserbjudande har använts vid analysen av resultatet. Uppsatsen utgår från tre stycken frågeställningar om hur definierar religionskunskapslärare begreppen nyreligiositet och nyreligiösa rörelser, om vad beskriver religionskunskapslärare att de undervisar kring nyreligiositet och nyreligiösa rörelser och hur beskriver lärare att de arbetar kring nyreligiositet och nyreligiösa rörelser i undervisningen? Resultatet i studien visar att lärarna har problem med att definiera begreppet nyreligiositet, vilket kan vara en orsak till att området får en marginell plats i religionskunskapsundervisningen.
Vilken uppfattning har operationssjuksköterskor om debriefing inom akutsjukvården?
ABSTRACT The aim of this thesis is to illustrate how surgical operation theatre nurses perceive debriefing within emergency health care. The study has a qualitative design with semi structured interviews that have been performed with seven operating room nurses working in emergency health care. The strategic selection consists of professional operation theatre nurses working in emergency care at Uppsala University Hospital. The main goal of this thesis is to increase the understanding of debriefing and to highlight the need of debriefing after difficult or unexpected events in the emergency health care profession.The interviewed nurses perceive debriefing as an important way to develop the day to day work, but also as a way to unburden the staff at the time of bigger traumas. Even though the effect of debriefing is not univocally positive in the literature, the staff perceives that it reduces different kinds of stress.

First of all, typical study characteristics of this time period are determined, then such characteristics are looked for in three of either Liszt's and Alkan's studies (from Douze grandes études S137 and Douze études dans les tons mineurs Op.
Folkbibliotekariers användning av sökverktyg på webben i referenstjänst
The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.
