Diversitet hos jordlöpare (Col: Carabidae) i hävdade strandnära gräsmarker :
Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands.
The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow.
The species composition was analysed by ordination analyses, i.e. DCA and CCA.
I sökandet efter framtidens destinationer : Ur researrangörers perspektiv
Background: The fast growing tourism industry increases the need for new destinations to meet the markets demand. Because of this, destination development becomes a part of tourism development and it can therefore be interesting and relevant to study this phenomenon. It requires consciousness about the destination?s conditions and to what extent tourism can be developed. The study of these conditions can be useful as they are fundamental for future tourism development at a destination.Purpose: The purpose of this study is to describe and analyze which conditions and characteristics a place should have to become an attractive destination.Methodology: This study has been executed from a positivistic point of view and a quantitative approach.
Vem hålls ansvarig? : En studie av de förändrade förutsättningarna för ansvarsutkrävande med avseende på svensk krigsmaterielexport
This thesis explores the changing prerequisites for accountability in terms of Swedish arms export. The study aims to uncover what has happened with the conditions for accountability in Sweden since the responsibility for export control was transferred from the government to the public administration. By investigating how the term ?accountability? has been used in the literature of democratic theory, an abstract ideal model is being created. Comparing the changed structural arrangements, with each other and the ideal model, it is concluded that the prerequisites for accountability now seems to be in a worse state than they were before..
Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.
Partialkoefficienter för stabilitetsanalys av betongdammar
I Sverige finns det idag ett stort antal dammar och nära hälften av Sveriges elproduktion kommer ifrån vattenkraft. Höga säkerhetskrav ställs på dammarna då konsekvenserna av ett dammbrott kan orsaka stor ekonomisk skada både i form av minskad produktion och som uppbyggnadskostnader. Dammbrott kan även utgöra risk för skador på människor och omkringliggande miljö samt byggnader.Det finns flera dimensioneringsmetoder för att uppfylla gällande säkerhetskrav på konstruktioner. De tillämpningsvägledningar som används vid stabilitetsanalys av betongdammar baseras på gamla deterministiska metoder med säkerhetsfaktorer. Det arbetas med att ta fram nya tillämpningsvägledningar baserat på sannolikhetsbaserade metoder.
MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20
An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.
Ekonomistyrning inom äldreomsorgen, Intraprenad eller entreprenad - är det någon skillnad
In recent years the elderly care in Sweden has gone through several structural changes with the main purpose of delivering a more efficient service. The aim of this study is to compare the management control system in a privately and a publicly managed elderly home. A qualitative study was conducted which included interviews, observations of meetings and reviews of relevant documents. To be able to identify possible differences the framework of Hood consisting of seven dimensions was used. An analysis of the selected dimensions showed that the differences in management control were minimal and Brunsson's theory of politicization and 'company-ization' were used to explain why..
Textens spegel till Narcissus´minne : Ett betraktande av den egna skrivprocessen
In this essay I analyse three of my own texts included in an unpublished collection entitled till Narcissus' minne. Genres are discussed and a detailed study of how the writing process has progressed is done. The essay does not follow any specific literary or scholarly method of analysis, but to some extent the sphere of interpretation is explored. By associative interpretation the special logic of dreaming, the activity of the unconsciousness and the expansive accessibility of the memories, which characterize the texts, is traced. These structural features open a link to the way of psychoanalytical interpretation, but the essay does not strive for a complete account.
Debattens tvärmediala rörelser - en studie av tre debattformat och deras förutsättningar
This thesis studies three kinds of debate formats. Those are DN Debatt, SVT Debatt and Ring P1. The focus lies in the interrelations between these forums and how they interact with theri audience. Since debate is an essential tool for political and democratic practice, it is vital to study the movements and the realtions between these media formats. Some of the questions in this study are: What happens with a debate topic when it moves between the formats? In which way are the formats democratic and what does their communicative forms mean for political practice and citizen participation? The study shoes how the interpretation of a specific term can expand during a debate.
Skolvalet: en investering i framtiden? : En narrativ studie om föräldrars resonemang kring grundskolevalet ur ett Bourdieu-inspirerat perspektiv
The thesis aims to increase our understanding about parents reasoning about the elementary school choice by studying which factors parents perceive as important during the decision making process and also by giving meaning to Pierre Bourdieu?s concept of capital through the parents perspective. The empirical material comes from seven BNIM-interviews made with parents, which has been analyzed according to the thematic field analysis.The results show that the parents are not especially concerned about making an active school choice. Stability, closeness, friends, rumors, development and adaptability to the reality are the factors that are perceived as the most important in the decision making process. The school choice has a limited meaning as an investment in social capital, from Bourdieu?s perspective.
Utveckling av modellbaserad reglering i kommersiella styrsystem
In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.
Pre-treatment of grain for ethanol production during storage
Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

During a period of one year a quantitative and qualitative study was performed within the social administration in a nearby community. The study focus is partly on the relationship between the law, family and society. The main questions have been: Which one of the parents, mother or father, did in fact get the custody and why? How has the children?s point of view been reported in the inquiry? A child needs a well organized everyday life in a preferably conflict free environment.
Hur ska skogsfastigheter värderas?
This thesis aimed to describe how the ideological dividing line concerning the welfare state has changed between the two largest governmental parties in Sweden, the Social Democrats and the Moderaterna, during 1990 to 2010. The scientist Mark Blyth points out that ideas are important instruments for structural and institutional change by identifying ideas as weapons, blueprints and cognitive locks, which were being used in the theoretical framework. The empirical data was made by a qualitative analysis of the parliamentary speeches and debates from both parties held every year. The results shows that the budgetary law passed in 1997 became a new institutional blueprint, which changed the political conditions for the Social Democrats. Furthermore, the results point to a change in the Moderaterna?s rhetoric concerning the welfare state to a more pragmatic view. .
Från mästare till kommunalarbetare : En undersökning om trädgårdsmästaryrkets status- och kompetensförändring under perioden 1920-1955
This study of literature from the period 1920-1955 has shown that the profession of gardeners in Sweden went through several structural changes in the early and midst 20th century. The gardeners knowledge, which used to cover the whole horticultural spectra, was due to that no longer appreciated or useful. Prior the 1920?s the gardeners, especially the skilled craftsmen working for the upper-classes, were the ones who led progression in the horticultural field forward and their qualifications were many and diverse. Due to many factors, such as low economic and social status, functionalistic style and the fact that the branch were rationalized and modernized in general, lead up to a point where the gardener of old no longer fitted in, in the much more globalized and modern world of the 1950?s. .
