Inom Human- Computer Interaction är användbarhet ett mycket centraltbegrepp. Användbarhet kan i sin tur delas upp i effektivitetsmått ochsubjektiv uppfattning. Det råder idag delade meningar i forskarvärlden huruvida det existerar en korrelation mellan dessa två mått. Om denna korrelation existerar kanske vidare forskning visar att någon av de två inte utgör en nödvändig del av användbarhetsbegreppet. Om så är fallet skulle detta kunna leda till enklare och billigare design och utvärderingsprocesser.

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

This study investigates the effects that commercial computer games have on young individuals social comfort and learning progress. As a systematic study of literature, scholarly articles have been analysed in order to illuminate the positive as well as negative effects on social comfort and learning progress that may come with playing computer games. The social effects have mainly been discussed with role-playing games, such as World of Warcraft, as starting point, while the learning effects have been coupled with strategy games, such as Civilization IV. The study does not simply declare how these games can be good for these factors, but also in what respect computer games may prevent the development of young individuals socials skills and learning progress. The study showed that in spite of perpetual prejudices against computer games in the technological age, computer games might actually be good to use as a tool in order to authorize the development of young individuals regarding learning and social aspects.

The aim of this thesis is to clarify the affect that preferential and regional trade agreements have on the World Trade Organization (WTO), as being establisher of the international trading regime. The essay is an explanatory literature study, which strives to answer the following questions:Are regional and preferential trade agreements a threat or a complement to the WTO?Is an undermining of the MFN principle weakening the WTO?How do regional trade agreements made by the EU affect the future of the WTO?The empirical material is to be analyzed using an explanatory framework, which is based on neo-liberal instutionalism, theories on regime changes and a game theoretical approach, using prisoner?s dilemma. I will employ the EU-ACP relation, the Cotonou agreement to exemplify how an agreement of this kind can have an influence on multilateral trade. The result shows that preferential agreements do have an impact on the WTO, one that is fairly negative in scope.

The purpose of this study was to examine the foreign news flow in Sweden´s largest news agency TT. Since TT has an important position as a news provider to most of Sweden´s local and national news outlets, it was important to examine exactly what their news stories consisted of.The theoretical background of this study consist of theories of news values, agenda setting, dependency theory and the theory about the ?news shadow? a lack of coverage leads to.In our quantitative study we have looked at 506 articles taken from the TT news flow during two weeks In November 2013. We have studied which continents and countries the news origins from, who have supplied the text, the topics of the news, which one gets to speak in the text and what general tone the story has.The study shows that the supply of news follows the criteria of news values. It also shows that in some regions of the world the coverage is almost nonexistent.

In Rio De Janeiro, 1992, was the first document signed that meant a responsibility for industrial countries to decrease their emissions, United Nations Framework Convention on Climate Change (UNFCCC). Thirteen years later was the first legal binding document signed, the Kyoto protocol, and for the first time industrial countries all over the world was bound to decrease their emissions on greenhouse gases. Within the framework of this commitment, three flexible mechanisms (Clean Development mechanism, Joint Implementation and Emission trading) were introduced with the function to reduce the economical costs of the commitment. The flexible mechanisms Emission Trading (ET) is what this report is about.The report starts with a description of carbon dioxide and it?s effect on the environment, thereafter comes a background review of the national agreements who lies as a ground to the implementation of emission trading as a management control measure in Sweden and the rest of the world.Keywords: United Framework Convention on Climate Change, Kyoto protocol, Flexible mechanisms, Emission trading, carbon dioxide .

The aim with this study was to gain knowledge about how parents who are visual impaired experience and manage the meeting with the world around them. To have children and to be visual impaired creates a complex situation. There is not only the problem how to manage the parenting in technical terms. The disability is also filled with stigma because it diverges from the norms of society. There is not only demands from society about how the parent should behave, the parent also create demands of themselves.

During the last few years the countries in the African continent have experienced an enormous increase in female politicians on a national level. Rwanda is even the country with the highest number of female politicians in its parliament in the world. Despite this development in Africa, the quantitative research on women's political representation in the world has not yet paid attention to the situation there. Some of the surveys that have been done have even excluded countries that do not fit the homogeneous pattern ? which is precisely the problem with African countries ? for it to be possible to explain the situation with existing theories.The intention of this paper is therefore to, with all of the 53 African countries included in the study, examine whether the already existing explanatory factors regarding women's political representation also can be applied to an African context to explain the situation there.

In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.

Companies around the globe all have one thing in common; they are surrounded by individuals or groups of individuals that can influence the company in one way or another. These individuals and groups of individuals are called stakeholders. This study in concerned with the importance of a company?s awereness of and relationship with which stakeholders surround them. The fact that more companies show awareness of responsible conduct, in particular of the environment and social aspects of management may be a way to build a strong corporate image.

Abstract? ?there is no reason?to assume that prehistorians cannot study ancient symbolism and beliefs. The question remains, however, how best to study symbolism within the material confines of archaeological research?(Fogelin 2007:63)With my essay I would like to bring up the meaning of the soapstonelamp for the Thule culture in Greenland. Humans in the arctic area, from the same in the north of Scandinavia to the inuites in Greenland, have a common way of viewing the world that stems from anemismen.

AbstractOil rich states all over the world share a common feature. They are less likely than other states, depending on other resources, to be ruled democratically. In this essay Saudi Arabia has been studied with the purpose of trying to find which mechanisms that lie behind why oil rich states do not have institutions or institutional change that promotes democracy.Saudi Arabia has the world's largest known reservoir of oil. The oil brings huge revenue each year to the Saudi Arabian government. Why have Saudi Arabia not developed democratically when their economic growth suggests that to be a natural step? Under the framework of historical institutionalism and path dependency theory, I have used process tracing trying to track the mechanisms behind Saudi Arabia's authoritarian rule down.

This is an art-remix project that focuses on a dream about art and music remixed and made within a context of nonviolence. The goal is to create temporary (and in the long term hopefully stabile) spaces of peace. It will be done within places where change needs to come, where it needs to be heard/seen/experienced. Weapon exports from Sweden are increasing even though there is research showing that nonviolent resistance in conflict is more effective. In this essay I discuss nonviolence and how I can implement that in my work to find a meaningful work for both me and my neighbours.

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this. Many companies feel forced to align their strategies to the environmental goals set by the community. Some of the emissions the companies? operations can be linked to business trips and it is therefore interesting to see how these can be reduced by using different performance measures.

This essay will focus on video and computer game violence. We hope to uncover, with the help of semiotics, according to Barthes design, if this kind of violence can have a negative effect on youth and adolescents. How intense is the violence and how graphic is it?. PEGI is the European measurement for game age limits.
