Media och Sverigedemokraterna : Kandidatuppsats i statsvetenskap 15hp, Institutionen för samhällsvetenskaper
This study focuses on nationalism in Central and Eastern Europe. Anchored in theories that this region historically has been characterized by a nationalism that is based on the ethnic group rather than on liberal or civic concepts, it is the purpose of this study to explore whether these theories still apply in recent times when the region has been liberalized, for example manifested in the entry to the European Union. The research question has been tested through analysis of the constitutions of a number of Central and Eastern European countries in order to investigate what type of nationalism that the states have codified in their basic political documents. The results show that some of the states give expression to the historical ethnic nationalism in their constitutions, which indicates that the theories still are relevant..
Systemintegration i praktiken : utveckling av ett offert- och kundhanteringssystem i ASP.NET
Allt större och större andel företag väljer att presentera och förmedla varor och tjänster via e-handel.

Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion
Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.
Kundorderstyrd tillverkning ? Påverkande faktorer, förutsättningar och problem : En övergripande studie om hur små och medelstora företag flyttar kundorderpunkten och går mot mer kundanpassning.
This study presents a holistic view of which factors small and medium-sized enterprises (SMEs) have to consider, in moving their customer order decoupling point (CODP) further from the customer, thereby becoming more customized. The study also investigate whether SMEs and larger enterprises differ in the strategic questions relating to what influences an enterprise to become more customized, which prerequisites are required and which problems enterprises should anticipate and prepare for. These questions are important, given that strategic change is challenging, and can take considerable time to accomplish; it therefore needs to be based on the right decisions. This study is motivated by the fact that the markets SMEs are selling to tend to become more and more complex and harder to anticipate. Increased globalisation and use of IT and ICT have lead to greater uncertainty in customer demand.
Den internationella kontextens påverkan över en nations demokratiseringsprocess under transitionen från ett auktoritärt styre till ett demokratiskt - En analytisk kategorisering
AbstractBachelor thesis in political science by Alexander Hassan, autumn 2008, ?Effects of external factors on a nations democratisation process during the transition from authoritarian to electoral democratic rule ? A categorical analysis?Supervisor: Tomas SedeliusIn recent years globalization has become a hot topic in understanding the world we live in today. Globalization has indeed had a great impact on international relations and with it a great influence on the domestic conditions that determine a nation?s possibilities. It is therefore rational to hold true that this also would apply to a nation?s democratic process.
Core self-evaluation´s och bassjälvkänsla som prediktorer av arbetstillfredsställelse?
Allt fler företag fördjupar sig i personalutveckling och arbetstillfredsställelse. Arbetstillfredsställelse har kopplats till begreppet ?core self-evaluation? (CSE), som bygger på fyra personlighetsdrag: generell self-efficacy, locus of control, neurotisism och självkänsla. Studien sökte svar på vilken inverkan CSE och bassjälvkänsla har på arbetstillfredsställelse samt om dessa variabler skiljer sig åt mellan yrkesgrupper. En enkätstudie med 103 respondenter i tre olika yrkesgrupper genomfördes i två städer i mellersta Sverige.
Mikroföretags kommunikationshantering, off- och on-line, på
konsumentmarknaden: en fallstudie på två företag
The purpose of this thesis was to highlight how different aspects of market communication are used when micro companies choose to use both Internet and store selling activities towards the consumer market. The thesis dealt with off-line and on-line communication considerations with focus on advertising, interactions, and relations. In order to achieve this purpose a case study was conducted, that revealed that the companies acted according to theories. The conclusions drawn from the thesis were that companies tended to rely on traditional ways of dealing with advertising and interaction. We could also see that relations were created as a result of unconscious behavior and that the Internet activities still were on a basic level..
Betydelsen av förändringar i DuPont-komponenterna för framtida operativ lönsamhet
The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..
Risker i flera dimensioner : Om kopplingen mellan designmönstret MVC och projektrisker
The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
Optimering av gödselgrep för halm
This thesis was performed at SverigeGrepen AB. SverigeGrepen is a company that hasone product on the market; a manure fork that is designed to be used for mucking inshavings or peat. The aim of this thesis was to develop a new manure fork that isadapted to be used in straw.The development started with a pilot study where experience of mucking wascollected to be able to understand what and why certain characteristics are importantfor the function and use of the manure fork.A basic concept was developed where the main function was fulfilled, which meantthat a separation between dung and straw could be performed in a way that wasbeneficial for the user.The work resulted in four concepts of how a manure fork could be used in the strawthat can be designed and constructed. The conclusion that the work gave was that allconcepts met the main requirements required by a manure fork to use in straw.However, concept four provides a good visual impression, while its benefits areassumed to be important qualities..

Rummets relevans : Besökares upplevelse av osäkerhet i relation till en lärandeutställnings rumsliga utformning
This paper discusses the feeling of insecurity in educational exhibitions. The study analyzes one exhibition at the museum ?Nordiska Museet? in Stockholm, and strives to answer how the question of spatial factors can influence the feeling of insecurity, and thereby also the information process.The following questions have been addressed: Can we speak of a spatial allocation problem of exhibitions that contain much information? What is the relationship between the exhibition's intention and visitors conduct A model has been designed with influence from wayfinding where the exhibition is divided into basic parts, which allows a detailed study of the exhibition, and of how the parts relate to each other. The research contains spatial analyze, observations as well as interviews.The conclusion is that we, in the scientifically investigated exhibition, can speak of a spatial allocation problem when the information seems to be an overload for the visitor..
Lever 80-talister som de lär - en studie av 80-talistchefer på Swedbank
Few generations have gotten as much media attention as Generation Y. Growing up in the digital age Generation Y has become very different from previous generations. An interesting topic is if this is reflected in the way Generation Y act as leaders. The purpose of this study is to describe what kind of leadership Generation Y prefers, to explore how individuals belonging to Generation Y act as leaders and finally to investigate if there is a discrepancy between these two perspectives and if so try to understand it. By reviewing existing research and conducting depth interviews with employees and managers at a Swedish bank we recognize preferences in a number of categories, which Generation Y require from leaders.
Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :
In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead.
This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.
