"Man vill veta hur det går i skolan"

In the fall 2011 a new grading scale will be implemented in the Swedish school. A government bill suggests a change of the scale from a three- to a six-point scale. The students will also be graded from the sixth class instead of today?s eighth. From the first year of the compulsory school the pupil will get a written judgment.

Bottensubstratets inverkan på föryngring av Flodpärlmussla

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

Större svartbagge Upis ceramboides i norra Hälsingland : förekomst, substratkrav och effekter av skogsbrukets naturvårdsåtgärder

Many wood living insects are considered threatened by modern forestry due to the reduction in amount of dead wood. During the last decade various methods have been used to enhance the quantity of dead wood in managed forests. However little is known how and if these methods are aiding saproxylic insects. The threatened tenebrionid beetle, Upis ceramboides, is already extinct in southern Sweden. It develops in white rotted dead birch (Betula spp) and requires sun-exposed sites.

?Det var väl ändå litteratur det hela skulle handla om?? ? En idéanalys av värderingar kring Augustpriset i svensk dagspress

The aim of this Master?s thesis is to examine values expressed towards the Swedish literary award Augustpriset in a selection of articles from Swedish newspapers published between the years 2000-2007. The questions posed in the study are: What types of values concerning Augustpriset are expressed in a selection of cultural journalistic articles? How is the relationship between intellectual culture and commercial culture reflected in the articles? How are positive and negative standpoints justified? How can Augustpriset and the journalists be understood as parts of intraconversion on the literary field? The study?s qualitative textual analysis is theoretically based on Pierre Bourdieu?s theory of the literary field. The method used for analysing the articles is idea analysis using dimensions constructed from Bourdieu?s description of two polarities, the intellectual and the commercial, of the literary field.

Förskolebarns kommunikation i leken : Lek, kommunikation och språk i sammanhang

The aim of this study is to observe Swedish preschool children in their natural habitat and without any intervention. Four different observations are made and thereafter analyzed. Throughout the whole study the subject of interest is the children's communication in their play. Children can communicate with each other in various ways, for instance with speech and without speech, i.e. with their physical language, aesthetic and multi language.

?Jag är en av de få som blir lycklig...? - bibliotekariers attityder och förhållningssätt på fem folkbibliotek till statens distributionsstödda titlar.

The purpose of this master?s thesis is to study attitudes and standpoints among a few librarians towards literature with state supported distribution provided by the Swedish Arts Council. By qualitative interviews with librarians at five different public libraries, the thesis examines which attitudes that flourish concerning the titles, how the circular of books is treated, where the titles belong on the literature map and if the system is producing a standardisation of this literature and if the conception of quality is relevant. We also study how the librarians relate to intentions of the Swedish Art Council with the distributed titles and how they regard their availability. Our theoretical framework is based on Hans Hertel?s model of five literary circulations and Theodor W.

Att välja och att välja bort: En kvalitativ studie av hur barnbibliotekarier motiverar sina inköp av barn- och ungdomslitteratur

The purpose of this thesis is to investigate how childrens librarians at public libraries motivate their selection and their purchases of fiction for children and youth. The aim is also to find out what is felt like a problem at the selection process and what is not. Six childrens librarians have been interviewed in this qualitative study. On a basis of a theory of literature pedagogic perspectives the librarians were asked how they look upon purchase of fairy-tales, classics, pulpliterature and literature that contributes to the debate about man and society. They were also asked about their opinions of Bibliotekstjänst, of criticism of childrens books and how they reason about their purchases in general.

Informationssökning i elektroniska informationskällor Valmöjligheternas vånda

The purpose of this thesis is to examine which factors influence librarians selection of electronic information sources, and to investigate whether librarians use of search strategies and search tactics changes depending on which information source they use. The electronic information sources are: online databases, Online Public Access Catalogues OPAC, World Wide Web, and CD-ROM databases. The theoretical framework is based on step 3 Select a source and step 4 Formulate a Query in Marchioninis information seeking model. The search strategies are divided into two categories: analytical and browsing strategies. In order to supplement the theoretical framework with empirical facts, 8 librarians were interviewed.

Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

En skildring av hur tredje världen framställs inom ett urval av västerländsk barnlitteratur utifrån en postkolonial teori : En kvalitativ textanalys

In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.

Varför måste de stora bara bestämma allting? : En studie om barns delaktighet på folkbiblioteket ur barnbibliotekariens perspektiv

A vivid democracy requires participation from those who live in it, including children. Unlike adults, children have special laws and regulations to ensure them their democratic rights. Librarians? decision on what to buy makes an impact to someone else, which puts the librarian in a hegemonic position. Therefore, the purpose of this bachelor thesis is to, out of the child librarian?s perspective, view children?s participation at the public library in the matter of purchasing literature.

Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Hur biodiversitet på ekosystemnivå skiljer sig mellan olika habitat

Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

Att tillgängliggöra kvalitetskontrollerade Internetresurser: en studie av två ämnesportaler och två samverkansprojekt

The purpose of this masters thesis is to study two subject gate-ways within the field of Swedish higher education and academic research, concerning structuring and selection of Internet resources to facilitate information retrieval for their target groups, and also to study two co-operation projects in the same field, one national and one European, to see how the co-operation is being carried through and how the gateways in the projects can serve from a wider perspective. The gateways, AGORA and NOVAGate, are being studied mainly by their Web sites and two e-mail interviews with persons responsible for the gateways. Facts about the national project are principally based on an interview with BIBSAM. The European Renardus is being studied out of articles and information on the Web site. From the results of the study it is being clear that the purpose of the gateways is to make a quality-selection of information accessible via the Internet and thereby facilitate for their target groups to find usable information.

Dödlighet hos gepardungar

Geparder minskar i antal och dödligheten hos ungarna är väldigt hög. Syftet med denna litteratursstudie är att ta reda på varför gepardungar dör och vad som är de största orsakerna. Geparder är utsatta för predatorer på två sätt; rovdjur kan stjäla deras byten eller döda geparder. Därför är studien främst inriktad på vilda geparder. Anatomin skiljer sig mellan geparder och andra kattdjur eftersom de är världens snabbaste landlevande däggdjur. De föder många ungar och har en hög reproduktionsförmåga.
