Vändbord : Lokal Logistik
This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.
En postindustriell stads dynamik : Kalmars samarbeten och konkurrenser i strävan efter expansion genom handel
The thesis strives to reveal the dynamics between a central and a peripheral shopping area in Kalmar, Sweden. The establishment of larger shopping centers has become a hallmark of postindustrial cities. Cities globally are at risk of creating an urban economic rift between the central and peripheral shopping areas. By establishing major shopping venues around the traditional central business districts, cities hope to create a larger customer hinterland and thereby also increased economic growth. The aim of this thesis is answered by two research questions regarding collaboration and competition between two shopping areas; the central Kvarnholmen and peripheral Hansa City Mall.
De externa etableringarnas framtid : en samhällsekonomisk analys av behov och möjlighet till politisk styrning och planering
The out-of-town retail establishments are part of the dramatic structural changes in the retailing of food and groceries. There are however strong indications suggesting these establishments result in negative externalities concerning areas such as pollution and urban environment. The purpose of this study is to describe and, from an economic perspective, analyse the Swedish political regulations and planning policies concerning the out-of-town supermarkets. The analysis establishes that the current regulations regarding out-of-town retailing do not, due to the occurrence of market failures, produce an optimal situation. It might therefore be necessary to change the planning policies in a more restrictive direction.
Broms- och styrsystem för möbeljalusier
This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

Establishing in China?s ?good-enough? market - - A benchmarking study on Scandinavian engineering industries? further establishment in China
Title: Establishing in China?s ?good-enough? market - A benchmarking study on Scandinavian engineering industries? further establishment in China. Problem discussion: The Chinese market is gaining importance for Scandinavian engineering industries and is by many considered a crucial market to be successful in. These companies have a tradition of producing premium products for premium customers. However, in China many are currently experiencing the threat from local competitors producing products of somewhat less quality aimed at the vast Chinese middle market - the good-enough market.
I handlingsplanens diskursiva spår : En studie av diskurser på nationell, regional och lokal nivå om våld i nära relationer
The aim of this study was to analyze how discourses about domestic violence emerges in policy and practice, and to investigate how those discourses may change from a structural, political level to a local, practical level. The research questions focused how the problem of domestic violence is formulated at national and local level, scrutinizing the different discourses framing and reproducing the causes and solutions of the problem, and also to deduce how different context affects formulations. The empirical material consists of policy plans and interviews with social workers. The findings indicates that the issue of domestic violence is articulated differently on different levels. In action plans on the national level, the domestic violence is formulated within a structural discourse, being a problem on a (gender-) political level, whereas professional social workers recognizes domestic violence as a personal problem within an individual oriented discourse.
Immigration och integration i kommunpolitiken : En studie av immigranters representation avseende förtroendeuppdrag i Växjö Kommun 1971-1991
The present study discusses the political integration of immigrants in local government in the muncipality of Växjö from 1971 to 1991 in the form of representation. The main data source consists of lists of people holding local commissions of trust in the various boards and committés appointed by the municipality council, as well as in the council itself. These data are then compared to population statistics from Statistics Sweden. Main findings of the study are that immigrants are insufficiently represented in relation to their proportion of the population. It is suggested that this is a result of structural discrimination and possibly insufficient socialisation..
Gruppdynamik i klassrummet : en studie om hur lärare arbetar med gruppdynamiken i klassrummet.
Vi har gjort en kvalitativ studie om hur lärare arbetar med gruppdynamiken i klassrummet. Vi utförde fyra intervjuer vilka utmynnade i fyra huvudområden: definition på gruppdynamik, synen på ledarskap, lärares strategier och kopplingen mellan inlärning och gruppdynamik. Informanternas bakgrund varierade från att enbart ha arbetat några år i yrket, till att ha 40 års erfarenhet. Vårt syfte med studien var att undersöka vilka strategier lärare använder när de arbetar med en grupp elever för att åstadkomma ett bra gruppklimat. Vi ville även synliggöra lärares tankar kring sitt ledarskap samt deras syn på kopplingen mellan inlärning och gruppdynamik.

The main conclusion that has been drawn is that the reliability of sprinkler systems in Sweden is 92 percent according to the analysis of Swedish statistics, and that this figure finds support in statistics from other countries. Further results are that the quality of design, installation, maintenance and inspection of sprinkler has to be improved and that the Swedish incident report has to be revised..
Ur askan i elden? : Om psykologiskt arbete med asylsökande barn
This phenomenological study explores the mental health problems of asylum- seeking children in Sweden and highlights possible ways of meeting their needs. Open interviews with 13 clinically experienced psychologists were conducted.The results of the analysis suggest that experiences of trauma and separation, the child's developmental level, parental functioning and family dynamics contribute to the mental health problems of asylum- seeking children. When meeting these children the psychologists continuously face ethical dilemmas since the asylum-seeking process seems to aggravate the problems as well as complicate the use of traditional interventions. Promoting structure and activity, normalizing symptoms, educating about trauma and crisis, sharing and accepting anxieties and sometimes thoroughly working through traumatic experiences are treatment strategies found clinically useful. Systematic follow-up studies are needed to decide the effects of these interventions..
Läsaren i den informella läsecirkeln
The purpose of this Master Thesis was to study the reader in the informal reading group. To fulfil our purpose we have used the following questions: how did the reader become a reader and what does her reading look like, why do people choose to participate in a reading group, how may the group influence the individual member in her reading and interpretation of a book, does the reading group have a therapeutic function, how does the informant find the group dynamics and different roles in the reading group, and finally how does the informant experience the discussion in the reading group. We have used two studies about reading groups, one by Elizabeth Long and one by Jenny Hartley. Our theory is divided into reading and group psychology. We have interviewed seven women belonging to different reading groups.
