Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.
PION Patientinformation on-line en brukarorienterad utvärdering
During the past decade, consumer health information-centers have been developed at the hospital libraries in Sweden in order to meet the increasing demand from patients and their relatives concerning consumer health information. In 1993, the hospital libraries in Falun, Västervik and Karlstad launched a consumer health information database called PION. The aim of this Master's thesis is two-fold. My first aim is to describe and discuss the principles of user-oriented evaluation. In my attempt to convey the theoretical discussion into the everyday life of librarianship, my second and most important aim is to conduct a user-oriented evaluation of the database PION.
Bildåtervinning för alla: Att tillgängliggöra bildsamlingar för en bred och ickespecificerad användargrupp.
This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.
?men kan vi inte hjälpas åt då? : en intervju med fem socialsekreterare om samarbete inom socialtjänsten
The aim of this study is to illustrate, and analyze how social workers are able to more effectively pursue operative possibilities within their own particular organizations. The main question concerning this issue is: How are social workers, working within the same district organization able to realise any potential for co-operation with other social workers, in different locales and units, yet working within the same organization? Following on from this question, further issues arise such as: 1. How do the varying demands of the clients affect the workload of the social worker? 2.
Skördemetoder av industrihampa :
Hemp is an old agricultural plant and has been used for hundreds of years for making
textiles, ropes and other fibre products. In the middle of the last century the Swedish
government prohibited all growing of hemp. Natural fibres were replaced by syntetic
fibres instead. Today there is a newly awakened interest for using natural fibres from
renewable materials. Growing of industrial hemp for fiber is allowed in Sweden
again.
I want in my Paper give Swedish growers an insight of which harvesting methods that
have been tried in Sweden and how they worked.
Japansk trädgårdsdesign i Sverige : en förlorad känsla
This is a BA thesis in landscape planning at the Swedish University of Agricultural Sciences in Alnarp. The purpose of the thesis is to investigate why Japanese gardens, created in Sweden, often lack the feeling connected with Japanese gardens.
The thesis includes a short study of Japanese history, spanning from the Middle Ages to the 19th century, to create a mild understanding of how the Japanese society changed, due to political, religious and cultural influences. The traditional Japanese garden styles, developed during this period, have been concisely compiled separately to create a homogeneous image of each style. In order to display opposite views of garden design in the European garden styles, some of the european styles have been concisely compiled as well.
To produce a higher level of understanding of the Japanese garden, a consice compilation of the fundamental design principles has been included, as well as variuos types of decoration typical to the Japanese gardens, since the miss-use of these is a certain way of losing the feeling of a Japanese garden.
The thesis is concluded by a consice compilation of possible reasons as to why the feeling connected with Japanese gardens is absent, as well as some attempt to include the feeling in the Swedish versions of Japanese gardens..
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.
Bland bovar och banditer. En analys av fyra deckare för barn ur ett genusperspektiv.
Swedish studies concerning children?s reading habits show that detective stories have become more popular in recent years. The aim of this bachelor?s thesis is to examine how the gender system is described in four detective stories written for children at the age of 9 to 13 years. Our main question is: How is the gender system reflected in the four selected detective stories for children? We also pose the question: How are femininity and masculinity described? Our study is based on three theories.
Är Leviathan giftig? : Autonomi och repression som förklaringar till regimskillnader i förväntad livslängd
During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.
Rekonstruktörens skadeståndsansvar
The thesis consists in two parts. The purpose of the first part is to analyse how the court may interpret rules, principles and legal cases to decide whether a reconstructor bears liability towards the debtor and the creditors. In the second part it is discussed and argued for how the reconstructor´s damage liability should be drawn up and applied so that it according to economic theories should be as efficient as possible. In the thesis it is shown that it is not a non-contractual liability or a liability based on authority mission. The reconstructor´s liability is instead based on a commission concerning an intellectual service.
Att utföra användarcentrerat arbete med små medel
Usability is a field within systems development which doesn?t get the attention it might deserve. Above all, it?s considered time consuming and expensive by many people in the industry. The current information regarding low-cost alternatives to achieve a more usable system seems to be almost non-existent.

Kontraheringsplikt inom förmögenhetsrätten ? Avtalsfrihetens gränser
Swedish contract law is based on the main principle of freedom of contract, which means that a contract is built on a voluntary agreement of both parties. There are exceptions from the principle of freedom of contract. In some instances a party is obliged to contract (kontraheringsplikt), which also is the subject for this paper. Kontraheringsplikt can be described as an obligation for one of the parts in a relation to come to an agreement under normal circumstances with everyone who ask for it. The cases of kontraheringsplikt are rather different.
?Att visa framsidan är självklart? ? Exponering av medier på folkbiblioteks webbsidor.
Several public libraries are displaying media, such as literature, on the websites of their own. The purpose of this Master?s thesis is to make a survey of the display phenomenon at Swedish public libraries. Therefore the authors of this essay seek to understand why media is being displayed on the websites of public libraries, how it is being displayed and what kind of consequences the displaying will provide according to the respondents. The theoretical framework is based on different theories where marketing and availability defines the equal summary.
Algebra och ekvationer ? att underlätta lärande : Lärandet börjar byggas vid första kunskapsmötet
Abstract This study aims with a pragmatic approach to investigate the learning about how to solve simple equations, and what the teacher can do to help the student. Four questions asked are: (i) How and why will learning take place? (ii) What will complicate learning? (iii) How to support and facilitate learning? (iv) Is it possible to identify an influence between identity and learning? To answer these questions a qualitative study in elementary school is done. The results of the investigation are compared with previous research, and an interview with the teacher is presented. The recorded lessons are analyzed with PEA (practical epistemology analysis), and letters from the students with the Ecological Systems Theory of Bronfenbrenner.
