Från frö till planta : En studie om hur elever i årskurs ett och fyra tänker om fröet och dess utveckling till planta
Abstract The aim of this study was to explore and describe the pupils' thoughts on seed and its development into seedling. Twenty nine Swedish pupils at the age of 7 and 10 years old were interviewed about their knowledge of seeds.It turned out that pupils often have so-called everyday belief to describe the natural science phenomenon by connecting their explanations to phenomena in everyday life to which they are familiar. To describe the process of seed developing into seedling is something that most of the pupils believe to be difficult and this resulted mostly in the answer ?it is growing.? Children have some knowledge about what seeds need in order to germinate but they do not mention the importance of oxygen as a component of seed to be able to germinate and grow. They mean instead that it is sufficient with soil, water and sun.The older pupils, however, are more often than the younger pupils able to connect their reflections to a more scientifically correct description based on terms belonging to the phenomena, though these terms sometimes are wrongly used.
Finns det daglig variation i resistans i de nedre luftvägarna hos häst?
Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.
Höghastighetståg - Är det framtiden?
AbstractConsider a ?uid being heated from below. The heating leads to an upward convectiveforce that is counteracted by the viscous forces of the ?uid. If the convectiveforce is large enough in comparison to the viscous forces the ?uid will be put in anunstable state.
Hårda dörrar : Om dörrvakters selektering av gäster på krogen
The purpose of this study was to examine in depth and analyze how and on what basis selection of guests managed by doormen primarily in an exclusive bistro in Stockholm. Qualitative methods in the form of personal interviews with door staff and participant observations were made. Interviews with doormen who work at two other similar places have also been carried out in order to find the differences and similarities in the selection process. To connect the results in a scientific way, we have mainly used Pierre Bourdieu's theories of capital forms and the field, and Göran Ahrne and Apostolis Papakostas organization theories. Previous research related to the phenomenon of selection in one way or another, along with the overarching theories, are used to answer the questions and purpose of this study.
Unga tjejers våldsbenägenhet vid konsumtion av alkohol
The purpose on this study is to determine the extent of possible connections between tendencies to increased violent behavior and increased alcohol consumption among a total cohort of girls in the 9th grade compulsory school and 2nd grade upper secondary school in a Swedish county. In 2004 the Epidemiological Department carried out a health-status survey, using a self-report questionnaire, with students from both private and public schools in a specific county in Sweden. All respondents (N= ca 4000), attending all compulsory (at 9th grade) and upper secondary schools (second tier) on the survey date completed the questionnaire. For this particular study, 9 questions from the questionnaire, all concerning self-reported violent behavior and alcohol consumption habits were used either individually or combined in index variables. The result showed that while violence experience is low among these 4000 girls, it increased in relation to a corresponding increase in alcohol consumption.
Sexköpslagens glömda kvinnor - En diskursanalytisk studie av bilden av prostitution i teori och praktik
In Sweden prostitution is by many considered to be a social problem that primarily affects women. To counteract prostitution is a political priority and as a result the purchase of sexual services is prohibited by law. Since the law that prohibits the purchase of sexual services entered into force it has been continuously debated and widely disputed. The aim of this thesis is to compare the image of prostitution found in the travaux préparatoires of the law with four sex workers? view of the phenomenon.
Skolans hjärna eller verksamhet på undantag? En studie av skolbibliotekets status sett i ett organisatoriskt perspektiv
This study is an attempt to shed light on problems and possibilities of the school library of the Swedish comprehensive school concerning library law and goals of the school and the school library. Many investigations about the role of the school library of the comprehensive school have been carried through. They have all more or less come to the same conclusions. In spite of Swedish library law and goal documents of the school library, the school libraries are often neglected, if not will and commitment are to be found among teachers. Using a model of the school organisation by Gunnar Berg, three cases of school libraries are presented and analysed in a larger organisational and political perspective.
Från det imaginära till normala familjer : Analytiska konvergenser
I komplex analys finns det ett antal olika konvergenser varav vi tittar närmare på några här. Bland annat hur likformig konvergens medför punktvis konvergens men att det omvända ej gäller. Vi tittar också på vad de har för samband med lokal likformig konvergens och normal konvergens dvs. likformig konvergens på kompakta delmängder. Slutligen kommer vi att se på vad som gäller för familjer och kommer då in på lokalt begränsad, ekvikontinuitet, Arzela/Ascoli, Montels och Runges satser.
Kejsarens nya kläder : En fallstudie på H&M:s Lagerfeldkollektion
As companies exert themselves to find new ways of achieving market dominance and stronger brands, the phenomenon co-branding has become increasingly popular. By cooperation between two different firms the combined effects can result in synergies not only on the balance sheet, but even through softer values such as Brand recognition, equity and larger market share. Recently the fashion company H&M launched a collection together with the esteemed fashion designer Karl Lagerfeld. The objective of this paper is to examine the effects the collaboration had on consumer?s attitudes towards the two brands.
Det förändrade underlivet : En undersökning om kosmetisk intimkirurgi borde omfattas av lagen mot könsstympning
The swedish law against female genital mutilation (FGM) prohibits procedures that removes parts of the female genitalia and thereby makes permanent changes in the body. The problem with the wording of the law is that it may also apply to the western phenomenon cosmetic genital surgery. This paper therefore examines if cosmetic genital surgery should be covered by the swedish law against FGM, by making a critical comparing analysis. The paper begins with comparing FGM with cosmetic genital surgery to prove that there are more similarities than differences between the procedures. By using the theoretical perspectives universalism and postcolonialism, the paper then examines why, particularly in the West, there is a different approach to FGM than to cosmetic genital surgery, regardless of the similarities of the procedures.
Simulated Annealing : implementering mot integrerade analoga kretsar
Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

The essay concerns corporation?s usage and consumer?s attitude towards the phenomenon Big Data. The aim is to analyse whether corporation-management and future ambitions concerning consumer data coincide with attitudes and opinions of today's consumer, and how these opinions reflect consumer behaviour online. The essay is limited to focus on how companies use consumer data in order to better understand and improve the efficiency of their marketing. A self-composed analyse-model was created using previous studies concerning Internet-usage in Sweden, previous management analysis of corporations use of Big Data combined with theory of Cognitive Dissonance. A questionnaire was then created with the analyse model as foundation.
Hur tre epistemologiska diskurser och hur synen på kunskapsorganisation inom dem manifesteras i text
Our purpose is to analyse three different epistemological discourses that exist in the social practice, Library and Information Science LIS, using the strategy for interpretation from the mimesis model by Paul Ricoeur and the terms from the critical discourse analysis by Norman Fairclough. The aim is also to explore there different views of knowledge organisation. We review previous research involving epistemology, knowledge organisation and discourse analysis in LIS. These show that there are many different epistemological standpoints and that later research has shown a more critical and sceptical state of knowledge organisation than earlier traditional positivist ideals. Discourse analysis is described as an important theory and method in LIS.

Att lova guld och grön energi : En diskursanalys av svenska energibolags CSR-rapporter
The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.
