?Fiskar, apor, hajar och vänner? - En undersökning om användningen av mobiltelefon och kamera vid besök på science centre

Under senare år har den privata och offentliga sektorn blivit allt mer intresserad av att investera i museum och science centres för att öka kunskap kring vetenskap hos allmänheten (Heath & vom Lehn, 2008). Den här uppsatsen handlar om kamerans och mobiltelefonens användning vid besök på ett museum och science centre. Syftet med denna studie, som en del i ett större forskningsprojekt var att kartlägga hur unga människors teknikanvändning ser ut under ett besök på ett science centre. Studiens två frågeställningar var: Hur används video och foto i samband med besök på Universeum av unga människor? Vilken roll har denna användning under och efter besöket för unga människor? Undersökningsgruppen för studien var barn och skolungdomar i åldrarna 6-19 år.Studien har använt sig av ansatsen Grounded theory med ett etnografiskt forskningsperspektiv, där observation, enkäter och innehållsanalys på befintligt videomaterial från YouTube (www.youtube.com) har gjorts.

Markanvändningens förändring i vardagslandskapet : en analys av utvalda delar i Wessmantorp

During the last 100-200 years people have change their way of living and the condition and need for survival is no longer depending on the agricultural work. The forestry has replaced the farming and a lot of the natural pastural have been lost. Wessmantorp in the north part of Skåne is an old place for forestry and farming where people have been living for several hundred years. Studies of selected parts of the everyday landscape, that earlier have been settlement with small crofter?s holding, show that the changes in the landscape mostly depends on the human factor and that a lot of the cultivable soil have been replaced with spruce. Some of the areas, which the earlier dwellings were placed, still contain some remains of old house foundations and stone fences and can regard as being of an historical value. The studies provide the reader with a short background, the place as it is today and the changes of the land use in Wessmantorp.

Kall potatis i forskningens namn: Konstruktion av ett kompendium som stöder utveckling av processkunskap inom biologiundervisningen i gymnasieskolan

Inom ramen för examensarbetet konstruerades ett kompendium som ska förmedla kunskap om den vetenskapliga processen genom integration av autentiska experiment i skolan. Materialet ska hjälpa eleverna att konstruera sina egna experiment och samtidigt bli medvetna om ?tänkandet bakom görandet?. Kompendiet riktar sig till elever i gymnasieskolans biologiundervisning, och kan med fördel användas inom kursen biologi breddning. Den experimentella metoden som används är blodsockermätningar med eleven själv som mätsystem.

Bibliometrin och humaniora: En bibliometrisk analys av litteraturvetenskapen

The aim of this Master's thesis is to study whether bibliometrics can serve as a method to analyse the humanities.To investigate this a literature study was conducted that examined previous studies concerning bibliometrics and the humanities. Furthermore a bibliometric analysis of comparative literature was carried out. These research findings were then further examined through the perspective of theories on intellectual and social organization of the scienceThe bibliometrical study includes 38 literature journals (11 855 articles in total) which were downloaded from ISI's Web of Science. The material was analysed by using co-citation analysis and co-word analysis. The results of the study are presented in five co-citation maps.

Produktivitet vid stubblyftning :

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

Jord i portföljen : jordbruksmark som en del av en investeringsportfölj

People who invest capital in promising projects as a profession are called venture capitalists. They are constantly looking for new investment opportunities. Recently, media have observed a growing interest in forest land as capital investment. This is because several fund and investment company market the possibility of safe return through investment in woodland, both in Sweden and abroad. When an investment in forests is seen as an acceptable investment option, focus turns to nearby areas, namely agricultural land.

Undervisning av teorier kring livets uppkomst och evolution i ämnet biologi på grundskolans senare år och gymnasiet. : Kan misstolkning av läroplanerna  leda till konflikter kring undervisning om evolution?

Recent studies indicate that teaching the theory of evolution in Swedish secondary schools is not as uncontroversial as expected considering that Sweden is often described as one of the World?s most secularzied countries. A recent study indicates that Swedish teachers have a varity of tactics to avoid coming in conflict with their students or even parents of students that believe they have a rightto dictate how evolution should be taught. This study had fourmain aims; the first being to analyse both the previous curriculum and the new to see how the teaching of evolution is adressed, and if any changes have been made in the curriculum. The second being to look into how teachers interpret the curriculumand if they have noticed any changes in the new curriculum which have had an affect on their teachingmethods? The third being if teachers have met resistance when they teach evolution and the origins of life, and if so, how do they deal with these conflicts? The fourth and final aim of this study was to see if instances of conflict are on the rise as indicatedin the literature.The results of this study indicate that there has been no siginificant changes made in the curriculum with the exceptionthat the new curriculum is more clear and precise as to what teachers are expected to teach and that pseudoscience, such as intelligent design, has no place in science classroomsexcept when teachingthe philosophy of science.

Chicago Area Project - ett exempel på hur deltagardemokrati kan genomföras?

There are lots of theories about participatory democracy, but rather few examples of how to create it in practice. In the 1930´s, scientists at the Chicago School, implemented some projects within the Chicago Area Project, with the aim to decrease the youth delinquency in the socio disadvantaged areas surrounding Chicago. In this thesis, I assess wether these projects, and in particular the one at the Russell Square Area, have some common features with the thoughts of two of the most famous participatory democrats, Carole Pateman and Benjamin Barber. My question is if the Chicago Area Project could be seen as an experiment in participatory democracy. I find that participatory democrats could benefit from the experiences of the Chicago Area Project.

Varför tycker du inte som mig!? : Livsåskådningars struktur, funktion och immanenta konflikt

This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..

Ideologisk inverkan på SAB:s klassificering av arkeologiavdelning J

The Swedish Library Classification System, known as the SAB-system, can be viewed as a product of the cultural and social norms and values in Sweden during the time in which it was created and subsequently reviewed. The main purpose of this master?s thesis is to examine the archaeology section J in the SAB-system, in order to observe if values and norms within this discipline had any impact on the Swedish Library classification system. Our intention is therefore to verify any correspondence between the choice of topics and hierarchical structure of that section, and the values and norms that ruled the Swedish society during the 20th century at large but with particular emphasis to the academic discipline of Archaeology. At the present, Archaeology is often disputed as a value-free interpretive science.

Växtdatabas med sökmotor :

My work has resulted in an interactive search engine for plants that can be found at www.plantit.se. In the work process I have searched for which search criteria is most important when doing searches on woodland plants. I have done this by an analysis of existing databases and with an survey where leading plant expertise answered questions about woodland plants. I analyzed three search pages that are on the internet today Havenet.dk, Backyardgardener.com and Den virtuella floran. I concluded that there are several flaws but also many positive aspects that I have used when developing the interface of my page. The survey resulted in the basis for my search criteria the answers listed the most important factors when planting woodland plants. From this information I developed a system with five values on every criteria.

Någon måste göra något! Institutionsplacering: en konkret och för-givet-tagen åtgärd för att hantera ungdomar med beteendeproblem

The purpose of this study was to increase the understanding of the phenomenon that there are so many young people placed in institutions in Sweden despite the valuable knowledge regarding the problems and risks of doing so. The questions that follow in the essay were what guided the social workers to choose institutional placement for youngsters. It went on to also ask if this knowledge could contribute to an increased understanding of why there were so many young people placed in institutions despite the criticism from scientists. To accomplish the goal of the essay, former science in the subject was reported and six social workers within social services were interviewed. The material of the interviews was analyzed with help from the theory of human service organizations, street-level bureaucrats work situation and the new institutionalism.The result of the investigation showed that the social workers choices to place young people in institutions is guided by specific work and organizational factors connected with a belief in the helping function of the surroundings.

Värdering av kvävet i organiska gödselmedel :

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Föräldrars utbildningsnivå : En studie om hur elevernas prestationer som påverkas av föräldrarnas bakgrund

This study is about how students 'performance in school is influenced by parents' educational background. The study has been performed by cooperation with two schools in Stockholm. One class in each school has participated and the students have amongst other questions answered regarding their grades in natural science subjects. To examine whether parents 'educational background affect students' performance, a quantitative survey in the form of poll has been conducted. Even a literature review was conducted in this area to get a clearer picture of how parents' educational background affects the performance of students.This study shows that students who have academic parents perform better than students who have not got academically educated parents.
