Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Hårda dörrar : Om dörrvakters selektering av gäster på krogen

The purpose of this study was to examine in depth and analyze how and on what basis selection of guests managed by doormen primarily in an exclusive bistro in Stockholm. Qualitative methods in the form of personal interviews with door staff and participant observations were made. Interviews with doormen who work at two other similar places have also been carried out in order to find the differences and similarities in the selection process. To connect the results in a scientific way, we have mainly used Pierre Bourdieu's theories of capital forms and the field, and Göran Ahrne and Apostolis Papakostas organization theories. Previous research related to the phenomenon of selection in one way or another, along with the overarching theories, are used to answer the questions and purpose of this study.

Effekter av "Billigaste väg" för Stora Enso Skogs transportverksamhet :

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

Utvärdering av viabilitet hos selekterad hingstsperma med hjälp av fluorometri :

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Urval av facklitteratur: En komparativ litteraturstudie kring beståndsutveckling av facklitteratur på folkbibliotek.

The aim of this study is to investigate methods of collection development, the users? influence on selection and quality aspects, focusing on non-fiction literature in Swedish public libraries. To find out opinions of collection development, I use the method comparative literature study. Antonio Gramsci?s concept hegemony forms the theoretical background, and hegemony as concept is related to a library context by using Maj Klasson?s text on the librarians? different positions of authorities.

Internetbaserad rekrytering: mål, möjligheter och praktiker : En fallstudie av urvalet vid rekryteringen av sommarvikarier i Luleå kommun

The purpose of this study is to examine web-based recruitment to short term summer jobs at the SocialServices Department in Luleå municipality in Sweden. Recruitment goals, selection options on therecruitment homepage Offentliga Jobb and recruitment practices were analysed in order to reach a deeperunderstanding of the interactions between these three levels in the selection process. Pre-selection throughOffentliga Jobb was a special concern of the study. Different consciousness levels in the selection process areemphasised according to Anthony Giddens' structuration theory. Ten recruiters from different parts of thedepartment were interviewed.

?Man kan inte läsa bara för att man kan tala? : En studie om årskurs ett-elevers föreställningar om läsning och bokval

The aim of the study is to investigate what pupils in grade 1 think about reading aloud, reading alone, the selection of books, and the significance of reading. A subsidiary aimwas to examine the relation between the pupils? experiences of reading in the home andtheir ability to discuss a text they have read. A sidetrack in the study aimed to see whether the pupils? experiences of reading in the home affected their outlook on readingin general.

Bedömning av spermiemotilitet i färsk, kyld samt selekterad hingstsperma med Qualisperm :

This EEF-project is a part of a larger project at SLU, Division of Reproduction, Dept of Clinical Science, with the intention of developing and evaluating new methods for the assessment of stallion semen quality. Over the last 10 years there has been an increase in the use of artificial insemination with cooled semen in Swedish horse breeding. At the same time, foaling rates have decreased. This has lead to a need for new and better methods of assessing the quality of stallion semen. This EEF-project was based on an objective method to calculate motility, with QualispermTM, in fresh and cooled stallion semen, and after selection. Today sperm motility evaluation is mainly done subjectively by visual assessment with a light microscope, and the correlation between these motility results and fertility have varied.

Genomisk selektion inom köttraser

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.

E-böcker på högskole- och universitetsbibliotek ? En studie kring det digitala förvärvet

This study aims to find out how the selection and acquisitions of ebooks made by university libraries is affected by vendors terms of sale.

Bilderboken i förskolan : Vad pedagoger tar hänsyn till när de väljer böcker

The aim of this study is to increase the knowledge regarding the selection process of picture books by pre-school educators. My intention is to find out which criteria educators use to select the books. I have restricted the study to pre-school educators, because I wish to find out how they work with the selection process and which criteria and considerations are included. I also want to know if the children have influence in the book selection and how the books get to the pre-school.The study is based on qualitative interviews with educators at a pre-schools in my area as well as relevant publications. The questions the educators were given were semi-structured.

Ekosystemstödjande och multifunktionella växtval i urban miljö : En fallstudie med utgångspunkt i Nacka stadsbildning

This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.

Gymnasieungdomars kostvanor under skoldagen och deras uppfattningar om skolkafeteriornas utbud

The aim of this thesis was to investigate whether the selection of products in the school cafeterias in Uppsala county high schools' comply with NFA's (National Food Administration) recommendations. Furthermore, the intention was to examine pupils´ eating habits before and during the school day, and their views on the school cafeteria´s selection of products. To investigate this, an inventory of school cafeterias in six high schools in Uppsala County, and a survey among 60 pupils were carried out. The results showed that the NFA's recommendations not always were followed. The survey showed that there were healthy products in the cafeterias but unhealthy products nevertheless constituted a large part of the selection.
