Centralitet och periferi i det nya Europa : Städer som regionala nav i samarbete och konkurrens
European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.
Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar
According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.
Det romska återtagande av sin identitet - En undersökning av identitetspolitik hos romska organisationer i EU
This thesis is concerned with investigating the Roma, a group that is left out in most of the territory bound theories. The theoretical purposes are to develop theories that increase the understanding for the Roma as a diasporic nation without state and the advocacy networks they are organised in. The main empirical purpose has been to study two organisations as cases and how they position themselves against the European Union concerning identity politics. The two organisations are European Roma Rights Centre (ERRC) and Dzeno. They are a part of the same network that works on different levels with the rights of Roma.
Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.
In your Face(book) users! En studie om socialt login och människans strävan efter konsistens
Concern about personal privacy continues to grow among online users along with the fact that new technologies help online companies to share user's private information. Still the usage of online entities such as social networks and e-commerce sites continue to increase. This raises the question of why online users act in such a contradictory and irrational way.Our study examines what impact one recently developed application called social login, which is provided by several social networks and used by millions of online companies, has on consumer's evaluation of online brands when they are primed for various types of information concerning privacy issues. Our assumptions are built up on the theory of cognitive, dissonance and suggest that there will be no differences in evaluation of the brands due to the human need to rationalize their existing behavior and attitudes when they receive new or contradicting information. The potential effects are measured by a manipulation presented in a survey distributed in an online environment to a sample of users (n=,154).

Miljömedvetenhet, miljöansvar och miljöbeteende En kvantitativ analys av det ekologiska medborgarskapets grunder
I samhällsdebatten om hur det hållbara samhället ska uppnås framhålls idag allt oftare individens bidrag till miljöproblemen samt dennes ansvar för sina handlingar och dess konsekvenser. Hur individbeteenden bäst förändras råder det dock delvis delade meningar om, och i den debatten står Ecological Citizenship-teorin för en syn på långvariga beteendeförändringar som styrda av vår inre motivation. Man antar ett samband mellan individens medvetenhet om miljökonsekvenserna av sina handlingar och dess beteende, och att detta samband förmedlas via en positiv attityd till individens personliga miljöansvar. Det är dessa samband som studeras i denna uppsats, med hjälp av statistisk analysmetod undersöks miljömedvetenhetens direkta och indirekta effekter dels på aggregerat miljöbeteende, och dels på tre olika typer av miljöbeteenden, nämligen resurssparande beteenden, transportbeteenden samt konsumentbeteenden.Resultaten av studien visar på att en indirekt effekt av miljömedvetenhet på aggregerat miljöbeteende via attityd till ansvar mycket riktigt föreligger, en dryg tredjedel av den totala effekten av miljömedvetenhet går vägen via ansvar. För de tre undergrupperna av miljöbeteenden framträder resurssparande beteenden som mest påverkade av både miljömedvetenhet och attityd till ansvar, men det är för transportbeteenden som den indirekta effekten utgör störst andel av den totala effekten.
Ekonomelevers extrajobb under gymnasietiden : Utvecklingsmöjligheter för studie- och yrkesvägledningen
The knowledge of early employment experiences has evolved over the last decade in countries such as Australia and Great Britain. In Sweden, this type of research is still unusual and the aim of this study was to break new ground by highlighting some areas that could be of extra interest in the Swedish early employment research to come. A focus in the study was to give an overview of what job sectors school students work in; and the amount of jobs aquired through school-organized work placement, private social networks or personal marketing of own merits. In addition to this, a multi variate analysis was carried out to find patterns in the picture of early employment experiences among students at upper secondary school. The findings of the study has relevance for ways of conducting career counselling and therefore the general aim of this study is to point out the importance of developing the practises of vocational psychology.A survey among 74 teenaged school students with economics as their main subject has been carried out in a mid-size Swedish city May 2012.
