In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.

A qualitative study is presented concerning children?s participation in the local decisionmaking in Swedish municipalities. The study also aims at finding out what are considered to be successful factors and obstacles connected to the implementation of children?s participation in local decision-making. The study contains a summary of the convention on the rights of the child, focusing on article 12, as well as previous research findings concerning children?s participation and factors enabling respectively hindering participation.

The purpose of this study was to investigate and compare how and why consumers of different ethnic backgrounds value and prioritize product attributes among food in certain ways. We expected to find culturally bound attitude differences and our aim was to relate those to, and challenge, present knowledge of information structures. Consequently, we also aimed to use this new knowledge of attribute attitudes in connection to assortment variety theory, as attributes constitute important motives to how consumers perceive variety. A theoretical framework was constructed to suit our purpose and function as an analytical tool, consisting of Culture perspectives, Information structures (product attributes), and Assortment variety. In this thesis we focused on attitudes and consumer perspectives and excluded actual behaviour and the retailing perspective.

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Several previous studies have in different ways tried to explain how new social movements are affected by the different sets of political and social contexts within different states and societies. This essay asks the question how much the institutional aspects within the theory of Political Opportunity Structures (POS) have determined how the rather successful animal rights movements in the Netherlands and Great Britain have mobilized and acted to gain progress. Since the Netherlands and Great Britain contains different kinds of political and institutional contexts, these two states are found to be suitable for a comparative analysis of the theory's durability. A qualitative portrayal of both state's institutional political opportunity structures are presented. Then the mobilization, progress, and actions of the political party ?Party for the Animals? in the Netherlands, and a wide group of animal rights organisations in Great Britain are determined.

This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.

Att en destination utstrålar en stark och positiv image har blivit en viktig faktor för att attrahera turister. En negativ global image av en destination kan bidra till en minskad turism. I denna studie söks en förståelse för hur Amsterdams image påverkas av sex- och drogturismen i staden. Teorier som bemöter primära och sekundära turistattraktioner, sökandet efter nöjes/meningsfulla upplevelser och image segmentering har satts i relation med insamlat empiriskt material hämtat från två enkätundersökningar samt tre semi-strukturerade intervjuer. Studiens analys visar att sex- och drogturismen genererar både en positiv och negativ image för Amsterdam i koppling till vad som är moraliskt riktigt.

The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.

The term ?vulnerable areas? is developed by the Swedish police, referring to various areas in Sweden that are classified as socioeconomically disadvantaged, and with an active criminal presence. Over time, this term has gained significant popularity and is now used not only by the police but also by other entities such as the media, where these areas are often depicted as urban outcasts. Therefore, this study focuses on the portrayal of ?vulnerable areas? in the Swedish news media, where the topic has been widely debated in recent years.

Since the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) was adopted in 1979 there has been evident progress in the area of women's rights in great parts of the world, although this progress is still foremost concentrated to the Westernhemisphere. In Argentina, the work with gender equality and women's rights set of strongly during the last decade. The country has ratified the Convention on the Elimination of All Forms of Discrimination against Women and the Inter-American Convention on the Prevention, Punishmentand Eradication of Violence against Women "Convention of Belem Do Para" but still women and girls are victims of structural discrimination and serious impunity of their rights on a daily basis.The current situation proves that the positive changes within the context of international and national law do not necessary reach out to the population to the same extent. In the light of the lacking popular involvement and knowledge of their rights, a different type of solution is desirable. Therefore it would be of interest to examinate the role of Non Governmental Organisations (NGO:s) when it comes to implementing human rights in the society and ?the every day life?.

Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv.

The fitting room is an important part of a clothing store, it's often where the customer decides if they want to buy the garment or not. Therefore it is important that the customer can feel safe and comfortable when they are trying the clothing. A typical fitting room in Sweden today has only one bright spotlight that emits light either towards the face or from the ceiling above. This study explores possible lighting solutions that take into account the customer's experience in the fitting room.The study aim to increase understanding of the importance of a good light in fitting rooms, so that customers gets a nice experience and that clothes, body shape and facial features are shown in a natural way. The issue therefore included how lighting can affect the customer's perception of the clothing and how the perception of body shape, facial features and the clothes change in different lighting solutions.To answer these questions, observations were made in various clothing stores, followed by an experimental study divided into two parts.

This study investigates how tagging is being used in a new way when members of a Swedish dating site get to tag themselves in an act of self-presentation with the aim of meeting new people. In the study seven members of the dating site Mazily were interviewed about their self-presentation, tagging and identity formation there. The questions concerned how they formed their own tags, but also how they interpret and use other members' tags in their search for a potential partner.I have been using queer theories for this study, in order to find out what kind of norms and structures that lie behind and affect the members' behaviour on the website. My study finds that the interviewed members to a high degree reflect about both their own and other members tagging and self-presentations. Although they spend quite some time trying to analyse other people on the website they have a great sense of understanding that a person may give two very different impressions on the site and offline.

The integration policy in Sweden has received criticism for being disintegrating due to the structure of division between those that integrate and those who are to be integrated, a division between ?us? and ?them?. In 2010 the reform Act on introduction activities for certain newly arrived immigrants (2010:197), was carried out to facilitate the integration of newly arrived immigrants on the labor market. The purpose of this thesis is to study power and discrimination structures within the reform by applying an intersectional theoretical framework. Intersectionality is based on the notion that different forms of discrimination such as gender, ethnicity, class, sexual orientation etc.

This is an analysis of how the Swedish newspapers Dagens Nyheter and Aftonbladet and the English newspapers The Independent and The Guardian reported about the sexual molestation and rape charges that were alleged against the Wikileaks founder Julian Assange in August 2010. Through a critical discourse analysis, a theme- and proposition analysis and a process analysis this paper aims to investigate how the above mentioned newspapers create reality in their articles. The purpose is to shed light upon with what means the journalists through the inherited structures of the newspaper illustrate actions and events, how they let other people get visible in the text and who is described as responsible for current events.    The results of the analysis shows that Aftonbladet uses a relatively large amount of propositions and speech cues to create an image of the reality that is almost explicitly angled. Dagens Nyheter and The Independent claims a higher degree of objectivity and through micro themes with different perspectives and few explicit statements they create a reality with plenty of room for the reader to make her own conclusions. The Guardian creates an image of the world where the Wikileaks is a great force of democracy and where actions are performed by humans as well as by objects and organizations.   .
