The findings of this thesis suggest that there appears to be a bad spiral. In countries with a lot of natural resources and poorly developed socio-economic structures, there is a present tendency to lower environmental protection laws in order to attract foreign investors by creating market oriented regulations. Investors and managers of multinational corporations will reduce production costs by m

Syftet med detta arbete var att designa och bygga en externt driven proteshand. Handen ska helst ha en eller flera funktioner som inte finns hos andra protester. Den mänskliga handen är väldigt komplex, den innehåller över 30 muskler och minst 18 leder.

Applying system justification theory, it was of interest to investigate its impact on Swedish citizens’ attitudes and behaviours related to sustainable consumption. This study intended to discover why Swedish consumers do not always en

Sedan slutet av 1990-talet har den arbetsrelaterade psykiska ohälsan ökat i Sverige och yrkesgruppen sjuksköterskor har drabbats hårt av detta, exempelvis genom utbrändhet. Studiens syfte var att undersöka hur väl work-family conflict (WFC) predicerade utbrändhet hos svenska sjuksköterskor, om fysisk aktivitet och skiftarbete var modererande variabler, samt om ålder och civilstånd hade någon påverSince the end of the 1990’s the work-related psychological illness has increased in Sweden and the occupational group nurses has been greatly affected by this, for example by burnout. The purpose of this study was to examine how well work-family conflict (WFC) predicted burnout among Swedish nurses, if physical activity and shiftwork were moderating variables, and if age and marital status had any

Detta examensarbete omfattar en studie av mätmetoder för etablerandet av geodetiska referensnät i tunnlar. Studien begränsas till endast mätningar i det horisontella planet. Verklig mätdata från projekt Hallandsås används, men även datorsimuleringar av stomnät utförs. Tunnelbygget genom Hallandsås är en del i utbyggnaden av Västkustbanan mellan Göteborg och Malmö. Två parallella tunnlar, ca 9 km This thesis studies different methods of surveying geodetic reference networks in tunnels. The study is limited to surveys in the horizontal plane. Real survey data from project Hallandsås is used, but computer-aided simulations are also done. The tunnel through Hallandsås ridge is a part of the extension of Västkustbanan, an important railway connection between Gothenburg and Malmo. Two parallel

The process of finding your identity is in constant motion and totally depending on the norms of society, parental values, and the impact the school and friends has over you. We aim to study the process of identity for youths born in Sweden with parents born in a foreign country, how they experiencing their identity and h

A simpler version of a shock-testing machine was developed and built. This allows engineers at Verisure to test prototypes and early versions of new products before the product is certified. An independent company shock tests the product as part of the process to certify it as an approved home alarm security product. During the shock test, the product is subjected to a high acceleration during a s

Public speaking is something that most people struggle with and the art of public speaking is something that is difficult to master. Traditional coaching usually consists of an expert teaching you a set of rules to consider and giving you feedback based on a presentation. Virtual reality (VR) based applications have been becoming more and more common over the last couple of years as an alternative
