En ny teoris framväxt : en studie om teoriutvecklingen inom barndomssociologin
This essay aims to examine how theories within childhood sociology have evolved. The main questions are: Who are the central scientists within the field, what are their objects of study and who are the intended recipients of their work? How can the origin of the theories be described? Which elements are central in the theories and have they changed over time? How can the theories be evaluated based on criteria of valid theories?The study was based on a qualitative literature review. Six scientists' publications were examined, ranging from the time of the theories establishment to present time. In the analysis hermeneutics and theories of scientific development were used to seek explanations.The main results show that the central elements in the theories describe childhood as a social phenomenon and a structural category.
Vegetationens roll i erosiva vattendrag : en review och fältstudie av två nyckelområden i Rönne å
The vegetation?s impact on erosion control is widely explored, even though research? results are scattered where it suggests a both positive and negative relationship between roots and erosion tendency. Research has measured the roots? impact on erosion by many different methods, hence the aim of this study is to offer a clearance of what factors play an important role in the choice of appropriate species controlling river bank erosion. I have therefore
studied 17 articles concerning vegetation and erosion control, which were found in different databases such as: Web of Knowledge, Biological Sciences, Academic Search Elite and Google Scholar.
Miljöutredning : ett fastställande av betydande miljöaspekter samt lagar och krav som rör Skaraterminalen Spedition AB
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
Möten i det mångreligiösa Sverige : En hermeneutisk studie av samfundsföreträdares erfarenheter av elevbesök.
Encounters between students and religious believers is common in the subject of Religious Education in Swedish schools. For pedagogical reasons teachers arranging these encounters hoping that exciting things will happen. But which qualities and experiences arise out of these encounters?In this study representatives of eight different religious communities are interviewed who regularly receive pupils coming to their respective communities. The proposed theoretical framework is related to Phenomenology and Hermeneutics and the methodological approach is interpretive.

Tradition, förändring och splittring - En diskursanalytisk studie av bibliotekariers yrkesidentitet
The aim of this master thesis is to examine the identity of librarians. We have done this by conducting a text analysis where we have analysed texts produced by DIK, the major union of librarians, and by Library and Information Science departments in Sweden. The material we have analysed is texts produced in the aim of introducing and marketing the librarian occupation and education. The aim of this study is to find out how the identity of the librarian is expressed in this material. We have conducted the text analysis by adopting the critical discourse analyst Norman Fairclough´s theories.
Plan för multifunktionella buffertzoner längs Vramsån på Malörten AB: s jordbruksfastigheter
To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.
As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.
Matematik - En studie om hur sex lärare i årskurs 1- 3 resonerar kring olika val av arbetsmetoder i matematik
The aim of my study is to examine how six teachers discuss their choices of work methods in teaching mathematics, as well as the methods they are currently using and what they have based their choices on. This study also covers how these teachers approach educational planning and where they get inspiration for their teaching material, and finally the advantages and disadvantages of each method according to the teachers. To be able to fulfill my purpose of this study some questions had to be considered: How do these teachers approach the planning of studies of mathematics and where do they find ideas for their lesson planning? Which methods do these teachers use in the teaching of mathematics and what are the reasons behind their choices of methods? Which advantages and disadvantages do these teachers see in the methods they use during the teaching of mathematics? This is a qualitative study, mainly based on qualitative research interviews according to an interview guide. Six teachers, from five different elementary schools, grade 1- 3, have been interviewed for this study.
Kan instruktioner om en rättvis och likabehandlande rekrytering leda till minskad diskriminering?
This study examined if individuals act in a less discriminating way and in a more fair way when they receive instructions about justice and not being discriminating while recruiting. 96 randomly assigned students at the University of Lund participated in this study. The participants were informed that they would act as a recruiter. They would then choose and place three of the best personal record in order of preference. There were three different kinds of company policies/instructions.
Mångfaldsarbete : En jämförelse mellan privata och offentliga sektorn
The aim of this thesis is to study whether social welfare secretaries experience occupational pride and what affects this feeling. Previously made research indicate that occupational pride is essential for performance and work-related health. Research has also shown that social welfare secretaries often experience unhealthiness due to working conditions and a lack of professional self-esteem.This thesis is based on four qualitative interviews which have focused especially on critical incidents, according to the critical incident technique. This study has a hermeneutic, interpretative approach. As a theoretical framework, Pierre Bourdieu? s theory on social space and positions aswell as Aaron Antonovsky´s theory on Sence of coherence have been used. The result shows that the interviewed social welfare secretaries do experience occupational pride.

Högtider och traditioner i förskolan : en kvalitativ studie om fem förskollärares beskrivningar och reflektioner kring firandet av högtider och traditoner i förskolan
This study is about the work around festivals and traditions that takes place in multicultural preschools. The purpose of this study is to describe and reflect upon the work around festivals and traditions in multicultural preschools from the view of five preschool teachers who are active in their profession. The purpose is also to investigate which festivals and traditions that are given attention at preschool and for what reason according to the preschool teachers.The method of research chosen in this study is qualitative in the form of individual interviews with the intention of obtaining and interpreting the descriptions and reflections of the informants around the subject. The results will be analyzed from an intercultural perspective.The results show that all investigated preschools celebrate the traditional Swedish festivals Christmas, St. Lucia?s day, Easter and Midsummer, and that these festivals take up lots of space in terms of time and labor.
Den h?gerpopulistiska paradoxen: Varf?r st?djer personer med invandrarbakgrund Sverigedemokraterna? En kvantitativ studie om h?rkomsten och medborgarskapets p?verkan p? st?det av radikala h?gerpartier bland invandrare
During the last decade millions of people have migrated to Europe. Parallel to this
development, we see that many countries are becoming more hostile towards immigration.
The success of radical right-wing parties (RHP) has been accredited to natives within the
receiving countries turning to RHP to reduce their perceived threat from immigrants.
Paradoxically, the RHP-support has also increased significantly among the immigrant
population given the common assumption that immigrants are in solidarity with regards to
shared experiences of immigration. In this dissertation, I argue for the importance of
considering the increased RHP-support amongst immigrants, something that has been
neglected in contemporary research.
