Tillfälligt fungerande konsensus : En interaktionistisk analys av samtal för att bedöma lärarstudenters kunnande under den verksamhetsförlagda utbildningen

Henriksson, Kristina (2009). Assessing student teachers through conversation - an interactional analysis of student-teaching conferencesThe aim of this study is to identify the characteristics of student-teaching conferences. During a school-based education for student teachers, teacher educators from the university visit the student teachers. They also have conversations, so-called student-teaching conferences, with the students school mentors to assess the student teachers knowledge. These conversations aim at assessing the student teachers professional knowledge at the end of a shool-based education.

Torrgranulering av slagg: Experimentell och numerisk modellering

Vid torrgranulering av masugnsslagg med roterande disk hälls den smälta varma slaggen i en stråle på den roterande disken. Slaggen slungas sedan radiellt ut åt sidorna från disken och sönderdelas till partiklar. Torrgranuleringen bidrar både till att en värdefull produkt i form av cement kan framställas, samtidigt som energin från den varma slaggen återvinns. I dagsläget finns dock inte tillräcklig kunskap om hur olika processparametrar påverkar sönderdelningen och storleksfördelningen av partiklarna för att kunna tillämpa processen inom industrin. Syftet med projektet var att skapa en experimentell och en numerisk modell av torrgranuleringsprocessen med roterande disk för att undersöka hur olika processparametrar påverkar sönderdelningen och storleksfördelningen på partiklarna, samt att utveckla en bildanalysmetod för att validera den numeriska modellen mot de experimentella resultaten.En experimentell modell av torrgranuleringsprocessen med roterande disk skapades i laboratorieskal och förenklades genom att vatten användes istället för masugnsslagg.

Kontextbaserad utveckling av klassifikationssystem: Värdet av ett användarperspektiv i en beståndsorganiserande process på specialbibliotek

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

Industriklassificeringens roll som urvalskriterium vid multipelvärdering

This thesis aims to investigate if peer-groups based on industry classification perform as well as, or better than, peer-groups based on other measures that represent factors affecting the price-to-earnings multiple. In contrast with previous empirical studies, a solid theoretical approach is used in defining which factors, according to valuation theory, affect the P/E-ratio. The factors identified as explanatory are accounting measures, risk and growth. Furthermore, we have recognized several measures that represent these factors. These measures are tested for accuracy of prediction in terms of the P/E-ratio for peer-groups based on these measures relative to an industry classified peer-group.

Musiken i Bolibompa. : Utveckling, utrymme och pedagogiska funktioner.

With inspiration from Bitzers situational analysis a phenomenografic method has been used, influenced by Brown & Levinsons´s theory of politeness, to find perceptions concerning constraints (in Bitzer´s sense in his model of the rhetorical situation) in Internet-based communication. Based on three qualitative interviews, this essay has found that the perceptions are closely linked to views of what constitutes formal and informal contexts, varying due to the gender or age of the informant. Netspeak is not considered appropriate, with some exceptions, in any formal situation. However, the perceptions regarding decorum in informal situations differ in nature, based mainly on what kinds of associations and connotations are produced by elements found in netspeak. Since perceptions regarding informal situations vary, there is a large risk of misunderstanding, which this essay aims to survey..

Utrymning av folkmassor - simulering och verklighet

The report contains a comparison between computer based modeling of evacuation and evacuation experiments with large crowds. Crowd movement, behavior and management is examined, as well as the evacuation time. The conclusions in this report are based on observations made during the evacuation of a football ground (Swedish)..

Manliga folkbibliotekariers upplevelser av att jobba inom ett kvinnodominerat yrke

The main purpose of this masters thesis is to investigate how male public librarians experience working in a female-dominated area by interviewing eight male public librarians. We want to find if our informants have experienced, or are experiencing, that the library users react differently to the male librarians, as opposed to the female librarians, with focus on possible prejudices. Besides this we want to investigate if the male librarians have had any reactions from their colleagues based on the fact that they are men working in a female profession. We are using three theories in this thesis. The first theory is based on an article by Christine L.

En studie i användbarhet: En kritisk analys av användbarhetsstudier i biblioteks- och informationsvetenskap

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Casemetodik och geografi : En studie av elevers och lärares syn på casemetodik i geografiundervisningen

The case method is a relatively new pedagogical method in Sweden that is based on students exercising their skills in the analysis of complex situations and problems that are based in reality and that help students to see a broader perspective and context.The purpose of this study has been to investigate, through interviews with students and teachers, the advantages and disadvantages of the case method in teaching geography.The results of the study show that both teachers and students share almost the same opinion. The conclusion is that the case method is a didactic method that is well suited for teaching geography, as it is based on reality and develops the students? ability to analyze, argue and find solutions in several areas within the subject of geography. If a student is strong in these skill areas they can really benefit from the application of the case method in the teaching of geography, but for students who are weaker in these skills, the case method can be a disadvantage.

Lepenski Vir - mellan floden och skogen. En uppsats om en mesolitisk bosättning i förändring.

This essay deals with the ideas of social change in the Iron Gates Gorge site of Lepenski Vir during the Mesolithic. The change from a mainly fish-based subsistence strategy to a strategy that came to rely more on hunting and later domesticated animals could have been the onset of the social change that is noticeable in the material culture from the site. Theessay is divided in two main segments. The first consists of a case-study based on three themes that describes and searches for changes in the subsistence-, settlement- and burialpractises during the Mesolithic and beginning of the Neolithic phases, and the second part analyses the results from the case-study. It is primarily the idea of transformations and reproductions of traditions that will be dealt with in the analysis which is facilitated by a theoretic structure based on and inspired by the works of Emilé Durkheim and Anthony Giddens..

Virtuella Communities: Sociala faktorer i digitala miljöer

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On the basis of our experiences, we describe the social elements that form the foundation on which the Virtual Community rely on.

Prototyp av informationssystem för militärfordon

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Evidensbaserad praktik och underhållsbehandling - begränsningar och möjligheter

It appears from today's debate about the quality of social work and addiction treatment that largely focuses on the impact of recent various interventions in the hope of being able to alter social work's role in society and also the organizational structure. The debate points to a part of the 1970s social welfare debate. Today's aspirations to establish an evidence-based practice can hardly be expected to solve the social services basic dilemmas is that it always have to do something, despite the many times you cannot get clear instructions on which funds should be used by law or science. Even if you follow the rules and practices based on scientific studies should the importance of various key initiatives to remedy deficiencies in social service work with addicts in large part depend on how, in these initiatives define the term "evidence-based practice" and what steps will be indicated for to develop practice. My starting point was to explore how evidence-based social work in connection with medication-assisted treatment for opiate addiction look, which evidence-based interventions Social Services currently uses in connection with medication-assisted treatment for opiate addiction, as well as how to work with it in the ordinary course of business. The study showed that social services have become better at using these methods in recent years and that today there are more tools available than before.
