Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling
Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.
Hur kvinnor med bröstcancer skattar sitt optimistiska och pessimistiska personlighetsdrag före och efter strålbehandling - en studie om stabilitet
Syftet med studien var att undersöka om det optimistiska/pessimistiska personlighetsdraget hos kvinnor med bröstcancer förändras av att genomgå en strålbehandlingsserie. Studien hade en jämförande design och urvalet var ett bekvämlighetsurval. Undersökningsgruppen bestod av 67 kvinnor i åldern 30 till 86 år med behandlingsbar bröstcancer. Kvinnornas personlighetsdrag skattades före och efter strålbehandlingsserien med hjälp av ett validerat mätinstrument, LOT-R. Enkäten bestod av tio påståenden som besvarades med hjälp av en fem-gradig skala ( 0="Stämmer inte alls,..., 4="Stämmer precis").
Man gör sitt jobb
It is a common-held belief that the social worker for the most part uses oneself as a ?tool? in working with clients. This study seeks to examine that ?tool? in the context of treatment of teenage boys with psychosocial problems such as criminal behavior, drug-abuse and/or abusive home environment. The main purpose is to identify the conceptions of masculinity, and more specific hegemonic and subordinated masculinity, of the professionals working with the boys.
Organisationskultur ur två perspektiv : En jämförande studie av två etnografier ifrån socialantropologi och organisationsteori

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.
Icke-värvningsklausuler : Finns behov av eget stadgande i lag?
The collective agreement contains many important provisions concerning the relationship between employers and employees. When a collective agreement applies in the workplace, both employers and employees are bound by it. However, only employers of those two, can take part in the collective agreement, and therefore negotiate the content of it.The purpose of this study is to answer the following question: Why are rules that has been interpreted in collective agreements not expressed in writing? Therefore, the Swedish collective agreement system will be examined, and a distinction between types of silent regulations will be made to find causes. The potential for workers to act on a collective agreement with quiet regulations will also be examined.Collective agreements are signed on three levels: central, union and local levels.
Implementeringen av Basel II-regelverket i Sverige : En jämförande studie över svenska storbankers kapitaltäckning

Sveriges bostadsmarknad i kris? : En kvalitativ fallstudie över Sveriges rådande situation på bostadsmarknaden och dess påverkan på finansiell stabilitet
Syfte: Att skapa förståelse för hur situationen på en marknad kan påverka den finansiella stabiliteten. Med det som grund göra en samlad bedömning om vilka risker som finns på Sveriges bostadsmarknad för att utvärdera hur och om de kan påverka finansiell stabilitet idag.Metod: För att ge oss en ökad förståelse om hur finansiell instabilitet uppstår på en marknad har vi tagit hjälp av Hyman P. Minskys teoretiska modell ?The Financial Instability Hypothesis?. Teorin har vi sedan applicerat på utvalda finansiella kriser för att studera vad som karaktäriserat dem i sin utformning.

Maskuliniteter : Genusnormernas inverkan på individers sociala förutsättningar
The purpose of the thesis Masculinities ? Gender and its Impact on the Social conditions of individuals is to perform a critical study of how gendered norms influence the social conditions of individuals. This has been done by a problematization and the attempt to answer the question of how the hegemonical masculinity can be analyzed as a discourse, and how the structural aspects of this discourse inflict on the social conditions of masculinities.The question was divided into the analytical themes: the boarders of the discourse, the institutionalization of the discourse, the actuation of the discourse and the agents of the discourse. The theoretical frame is constituted by the theory of discourse by Michel Foucault, the theory of the hegemonical masculinity by R.W. Connell and a subversive identity theory by Judith Butler.
Välkommen till Kanarieöarna. Våldsam skillnadspolitik i bemötandet av turister och båtflyktingar
This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go. To analyze the case I use theories of how differences in ethnicity, culture and religion etc. are created and recreated in society in interactions among humans and in the politics - the politics of difference. The politics of difference creates and recreates categories of mobility such as tourists and boat migrants.
Bilen - Om samhällsteori och samhällsförändring
The aim of this paper is to empirically examine the ideological trends and positioning of the Swedish liberal party with the Danish social liberal party. This paper also aims to analyze the reasons behind the trends. By examine the development in these two Nordic liberal sisterparties, this paper contributes to our understanding of why and how party change is initiated. The paper commences with an intuitive notion that the Swedish party has in fact, made a lurch towards the right, during the past ten to fifteen years while the Danish party has retained their social-liberal position in the centre of the Danish political spectrum. The questions then asked are: can this hypothesis be verified empirically? If so, how can this phenomenon of divergence, be explained?The method used in this thesis is process-tracing and the empirical material does to a large extent rely on interviews with central agents as they are specified in the theory of each party.
Kunskapens konstellationer: om ämnesanalys och tvärvetenskaplighet
The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
