The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.

Preventive measurements as well as clinical caries diagnostics are vital to retain a good dental health in the population. In order for optimal caries diagnostics radiographs are used. There is a great intra- and intervariation regarding cariesprogression. A large number of tools for cariesprevention at home or in the clinic are today used. The aim of this journal study was to compare the progression of carieslesions in the approximal area, diagnosed on radiographs, and preventive measures used to reduce cariesprogression between two examine dates on two dental clinics.

Arbetet har utvecklats utifrån min nyfikenhet över varför Sveriges utbrändhetsrelaterade sjukfrånvaro är bland den högsta i västvärlden. Det kan ses som att det är av stor vikt för företag liksom för individer att studera varför den utbrändhetsrelaterade sjukfrånvaron är så omfattande, då konsekvenserna av dessa är mycket krävande och kostsamma. Det finns redan mycket forskning på området men likväl är situationen i stort oförändrad.Syftet med uppsatsen är att undersöka vad beslutsfattande parter i sjukskrivningsarbetet har för uppfattning om den utbrändhetsrelaterade sjukfrånvaron samt undersöka om sådana uppfattningar kan kopplas till fenomenets bestående karaktär.I min empiriska undersökning har jag använt mig av kvalitativa intervjufrågor och min forskningsansats har varit fenomenologiskt. Jag har utarbetat tre forskningsfrågor, utifrån vilka jag sammanställt och tolkat resultatet. Dessa tre frågor möjliggjorde även att besvara syftet med arbetet.Undersökningen visade att respondenternas uppfattning om begreppet "utbrändhet" var av betydelse för deras förklaring om var utbrändheten härstammar från.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The purpose of this study was to investigate how the special education, for children with language impairment in preschool, was organised in a municipality in Sweden. The study was based on interviews and field studies as the primary research tools in qualitative and ethnographic method. The result showed that special education teachers were localised in different geographic areas of school and that there were preschools that lacked special educational expertise in language impairment. Literature and the importance of playing for language development were emphasised as well as the use of signs and visual aids as augmentative and alternative communication. In the preschool for children with language impairment, the teachers carried their knowledge into practical and pedagogical work.

The aim of this paper is to see how the local authorities in Norrköping create a way to look at homelessness. This aim is examined with the help of the central questions: How does the municipality describe homelessness as a phenomenon? What causes to homelessness can be seen in the texts? How do they describe homeless people? And What kind of actions are used or proposed? The analysis has been done with the tools and thoughts of the critical discourse analysis and made on text documents written by politics and employees of the city of Norrköping. The theories which have been used are those of postmodernism, welfare, homelessness, civil society and relative poverty. The analysis shows that the way the municipality of Norrköping looks at homelessness correspond with the way homelessness is presented in current Swedish research.

At the Women?s House in Örebro, a children?s project has started where the work method ?Oasen? [Oasis] model has been developed by two children?s educationists. The aim of this study is, with the ?Oasen? model as a starting point, to deepen the knowledge of (1) how to meet children?s central needs while staying at a Women?s House and (2) what the ?Oasen? model may contribute to the children. The theoretical framework consists of a cognitive approach to the progress of children experiencing domestic violence and a presentation of conceptions concerning children?s needs.

I dagens samhälle talas det mycket om vad bra ledarskap är, vilka positiva följder det för med sig och vad man kan lära av dessa ledare. Dock förekommer det i många fall även dåligt ledarskap. På senare tid har fenomenet destruktivt ledarskap uppmärksammats mer. Ett fenomen som dock ännu inte utforskats i så stor utsträckning. Denna uppsats har till syfte att analysera hur ett antal faktorer kan skapa förutsättningar för destruktivt ledarskap.

Purpose: The purpose of the essay is; to explain and clarify how the company is acting to lead members in social media to achieve valuable external communication. The authors believe that it is important to act with credibility and quality in social media, to accomplish long lasting relationships. When employees communicate with consumers their conduct is relevant to the company's credibility.Methodology: An inductive approach has been used for the empirical data collection since the authors have been studying the reality without existing theories. A qualitative research method has been used for collecting the empirical material. Primary data was collected from telephone interviews with seven companies, active in social media.Conclusions: The study shows that the power of employees? can be used when designing strategies for social media.

Title: Defending one's origin ? a musical journey to Transylvania.A journey to the Transylvanian part of Romania was pursued with the intent to investigate the cultural aspects of the historically and politically rooted set of relations between the Hungarian peaking minority and the majority of the population, the Romanian speaking group. Music pedagogical ambitions within the two cultures were used as reflections of these phenomena. In trying to shed light on my questions and extract the relations between the dominating and the dominated in this specific cultural and social context I have used the central themes of Bourdieu ? capital, habitus and field.

Syftet med denna studie är att, utifrån ett matematikdidaktiskt perspektiv, undersöka hur derivata introduceras i gymnasiets kurs Matematik C. Vi har i huvudsak fokuserat på didaktik och kognitiv utveckling. I en genomgång av relevant litteratur har vi tagit del av teorier och resultat från tidigare forskning inom samma område. Litteraturen försöker besvara frågan om hur lärare på bästa sätt kan överbrygga kognitiva hinder och ge elever en djupare förståelse kring de matematiska sammanhangen.Vårt material består av kvalitativa intervjuer med lärare från två skolor och ett antal läroböcker. Genomgången av intervjumaterialet har resulterat i fyra teman att använda som grund för hela studien: allmänt lärande, matematiklärande, derivatbegreppet samt visualisering.De lärare vi intervjuar vill alla stimulera elevers intresse för mer avancerad matematik.

Personalkontoret på Lunds tekniska högskola intresserade sig för universitetsadministratörernas speciella situation på sina respektive institutioner. För att undersöka detta fick jag i uppdrag att skriva en uppsats, där syftet blev att beskriva och analysera institutionsadministratörernas uppfattning om sin kompetens och sitt lärande inom LTH. För att finna svar på detta, utförde jag intervjuer med administratörer och medmedarbetare från personalkontoret.Resultaten visade att administratörerna hade många olika arbetsuppgifter, där de såg betydelsen av sin arbetslivserfarenhet för att ha lärt sig sitt arbete. Mycket av lärandet skedde framför datorn där arbetsuppgifterna utfördes i stor utsträckning. Informationssökning via hemsidor ökade och ansågs i vissa fall som svår.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.
