Bland ölmagar och spiror En studie av 1960- och 2000-talets detektivromaner ur ett genusperspektiv.
The aim of this Masters thesis is to examine how the gender structure appears in detective novels and in the society during the 1960s and 2000s. We have a pre-understanding that the gender structure is more distinct in the earlier books and we will investigate this by looking at the two aspects occupation and family role. We find this to be an important question to notice because society today isnt equal between the sexes. Our study is based on a theory of Yvonne Hirdmans, she claims that the man is the dominant part and the woman is in an inferior position. We apply a stereotype model she has conceived and we try to categorize the characters in the books we have analysed into this model.
Tidsperspektiv som prediktor för individuella skillnader i upplevd stress : En tvärsnittsstudie av äldre vuxna
Time Perspective is related to mental and physical health. This study examines the relationship between Time Perspective and perceived stress where Time Perspective was expected to predict the level of perceived stress. Past-negative, Future-negative, Future-positive and present-fatalistic were expected to be positively associated with perceived stress while Past-positive and present-hedonistic were expected to be negatively associated. Measures from the self-assessment forms S-ZTPI, PSQ-recent and CES-D from 445 participants (242 women, 203 men) between 60-90 years were used to examine the hypothesis of the study. Two hierarchical multiple regression analysis confirmed that Time Perspective is associated with perceived stress and in part 2 explains it's variance, one when adjusting for demographic data (.R = .37) and the 2 other when adjusting for demographic data and depressive symptoms (.R = .13).

It has also been shown that there are links between companies capital budgeting and their growth.
Centrala logistiska faktorer i en förädlingskedja för massproduktion av träpellets : Fallstudie på Kopparfors Pelletsfabrik
This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.
Folkbibliotekets roll på landsbygden och i staden
The purpose of this master?s thesis is to examine whether the role of a public library in a rural community is different from that of a town library. To answer this, a case studie of two public libraries has been made. Interviews, collection of documents and observations were carried out on location in one public library located in a rural area, and one public library, situated in a town. A modified version of an analysis model, originally developed by Andersson and Skot-Hansen, was used to analyse the data.
Förmågan att leda en klass - något som kommer med tiden
During my practical training I have seen what after-school offers children. Large groups of children and little staff, often results in that the children had to play freely until they go home. Few activities are offered to the children and the staff is busy looking after the children and ensures that they are not fighting.The purpose of this study is to find out how children feel about their leisure activities and if they think they are being offered a meaningful leisure. The main research questions were:How do children experience their leisure-time?Do after-school offers children a meaningful leisure and is it the children's interests and needs that govern the activities and the environment?How do the number of children in the leisure group affect the leisure time?The methods to collect data in the study are observations and interviews.

However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.
Automatiserad validering av funktionen hos ett datalager : en praktisk tillämpning av model checking
Företag förlitar sig ofta på datalager som aggregerar information från flera källor och över tiden. Dessa datalager är ofta centrala för beslutsfattande inom företagen, både kortsiktiga operativa beslut och långsiktiga strategiska. Eftersom information är en färskvara blir det allt viktigare att de dagliga laddningsrutinerna för datalagren fungerar. Denna rapport avser att analysera möjligheten att applicera principen model checking för en validering. Praktiskt avses att på ett automatiserat sätt använda Promela och Spin som verktyg för att validera att laddningsrutinerna för datalagret är korrekta..
Barns religionsfrihet i förskolan : En kvalitativ intervjustudie
AbstractMany opinions are divided on what religious freedom should protect and the area is unexploredin preschool. Is it the parents, the child or preschool teacher right? The aim of the studywas to investigate Maria klasson Sundin´s concept and theoretical models of religious freedomfor children through three Swedish preschool settings and also how three teachers interpretsand expresses children's freedom of religion. Through a qualitative interview study theaim was to investigate how the concepts of religion, autonomy and freedom is interpreted andexpressed by the teachers so a picture through this three concepts can categorise the teachersin a model; freedom of thought, tradition and life interpretation model so a broader picturecan be made to understand how the children's freedom of religion is expressed in the preschoolsetting and how the teachers work. The Result showed through the analysis that themodels fail to categorise the teachers in any theoretical model but on the other hand the understandingof preschool teacher?s expression and interpretation of the concept of religion,autonomy and freedom showed both diversity and lack of knowledge on the subject mattersreligious freedom which fall within the child rights issues.
Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3
The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.
Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff
In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.
Effect of cow traffic system on cow performance and AMS capacity
Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.
Det förbryllande sambandet mellan risk och avkastning : En studie av de nordiska finansiella marknaderna
Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.
