Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Att starta eget - en väg till frigörelse? En kvalitativ studie om mikroföretagare i Sydafrika
The aim of our study is to explore the empowerment process among micro-business owners in Kayamandi, a black township of Stellenbosch in South Africa. What are the positive and negative implications for the empowerment process? Another aim is to find out the role of local and international support in this process. The theoretical framework of this study revolves around the concepts of gender, power and empowerment. Our methods are qualitative interviews and observations.
Organisatoriska mellanrum - En övergripande förklaring till ägarlägenhetens dåliga genomslag?
In year 2009, a new housing form (here referred to as "owned apartments", in Swedish called "ägarlägenheter") was introduced in Sweden. Owned apartments are in many countries the dominating form of housing tenure, but in Stockholm, to where this thesis is delimited, only four have been established in four years. There are many possible reasons for this low establishment, but the thesis writers believe the main reason to be that the owned apartment is situated in an organizational gap. With the hypothesis that the owned apartment is situated in an organizational gap and that there are opportunities to overcome this gap through interorganizational collaboration of the players on the market, this thesis strives towards examining if this is the case.By using Burt's theory of structural holes the concept of organizational gaps are elaborated to fit this context, since this area is previously unexplored.The data has mainly been gathered through in-depth interviews but also through secondary sources such as previous theses and newspaper articles. It has appeared that the majority of the central players are characterized by conservatism.
?terfall i brott som ett problem p? politisk och institutionell niv?. : En kvalitativ unders?kning av sambandet mellan straff och rehabilitering inom svensk kriminalv?rd.
This study looks at how probation, client experiences, and criminal policy decisions affect recidivism in Sweden. Gaining a thorough grasp of how social, organizational, and political issues interact and impact the chances of rehabilitation and reintegration is the goal. Three research questions are addressed in the study: First, what are the causes of recidivism? Second, how is probation perceived by staff and clients in terms of control and support? Thirdly, what effects do political decisions have on probation services' operations and clients' chances for recovery?? A qualitative study was conducted with semi-structured interviews with twelve respondents, eight probation clients, three probation officers and one parliamentary politician. There were six themes that discussed the issue of recidivism from different perspectives, the collected data was analyzed through thematic content analysis.
Det krympande klassrummet : En studie av högstadielärares förutsättningar i ett reformerat skolsystem
Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).
Voluntary Redundancy - A tool for restructuring or a temporary pain reliever?
This thesis has two aims: The main purpose is to describe and illustrate how a large Ltd. company can use voluntary redundancy as a tool for restructuring. The additional purpose is to challenge the concept of voluntary redundancy trough outlining alternative ways of reaching the intended achievements of the voluntary redundancy programme. The theoretical framework that has been used primarily contains knowledge assets theories. The chosen theories are intellectual capital and knowledge management theory to approach and analyse the empirical findings.
Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar
Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.
Årstidsdynamik för kvicksilver i ett sövattensediment :
The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment.
The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake.
Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.
Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Design Program for Dessie Campus, Wollo University, Ethiopia
A geographical position and its social, cultural and political context as well as climate
and specific physical characteristics define the scope for a landscape design project.
This has become clearer for us in our master project where we have made a Design
Program for the outdoor environment of Wollo University in Dessie, Ethiopia and
analysed and reflected on the work and process. The aim for the project has been
to design an attractive and functional outdoor environment for the Campus, based
on the inventories and the needs and wishes of clients and users. But, the aim has
also been for us as landscape architect students to gain a greater knowledge about
landscape architecture and the design process by position ourselves outside our usual
context. The method has been open and seeking where the site, literature studies,
dialogues with people and our own experiences from the field study in Ethiopia has
influenced the work.
Wollo University is situated 400 kilometers north of Addis Ababa, in a
mountainous landscape. It faces problems of heavy rainfall during the summer,
soil erosion, a lack of essential facilities, and is still a construction site with empty
spaces in-between buildings and infrastructure.

Styrdokument i musikämnet : ? En komparativ studie av norska och svenska styrdokument i musikämnet i skolan.
Abstract:Styrdokument i musikämnet-En komparativ studie av norska och svenska styrdokument i Musikämnet i skolan.(Music Subject governing documents- A comparative study of Norwegian and Swedish policy documents in the Music subject in school)The purpose of this study is to compare the Norwegian and Swedish policy documents on teaching in the Music topic. The comparison also applies to the requirements which have been in Sweden over time. In comparison, the policy document LGR 11 from Sweden, analyzed, and the governing documents MUS1-01 and R94 from the Norwegian School.The main issue in the study is: How does the policy documents for the topic music in Sweden, compared to Norway? In order to answer the question, I compared the above-mentioned policy documents and set in relation to the musical substance is designed in Norway and Sweden.In curriculum theory treats one problem based approaches in structural functionalism, pragmatism, social epistemology and post structuralism. The starting points are then used to explore various relationships between curriculum theory and didactics.The principal researcher and proponent of curriculum theory is Ulf Lundgren.
Gymnasieelever och fostran av demokratiska medborgare : En enkätstudie av elevgruppers nivåer av moraliska och kognitiva utveckling.
This study is grounded in an interest in the Swedish Upper Secondary Schools? role as an educator of democratic citizens, with a specific interest in the moral and cognitive development of Upper Secondary School students. Development in these two areas is treated as results of citizenship education.The purpose of the study is to examine moral and cognitive development of students in Upper Secondary School to see if there are any structural differences to be found between the Upper Secondary School programs that are vocationally oriented and the programs that are preparing for further studies on higher levels ? since these differences have been both theoretically and empirically implied. The study is based on an enhanced version of Lawrence Kohlberg?s stages of moral development (with teachers? evaluations of students? capacity as a reference point of the students? actual level of moral development) as well as on Kieran Egan?s theory of development through the use of cognitive tools (as seen in five different ?shapes of understanding?).
Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer
Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.
The Swedish liming operation : a study about liming officers opinions about some aspects regarding ecology, economy and organization
This is a study about the Swedish liming operation and the Swedish liming officer?s opinions of some aspects regarding ecology, economy and organization. The study objectives was motivated due to the recent changes in manuals for the assessment of limed waters and the suggested changes in decision making and decreased budget for liming. Moreover the anthropogenic acidification effects on the ecology are in many ways complex. Furthermore it was made in order to gain knowledge about the liming officer?s opinions in order to improve the ability to meet their needs regarding the assessment tools and also to investigate if other things can be improved concerning the liming operation.
