Sixtynine students answered the questionnaire.Results: Over 50 % of the respondents experience annoyance from noise in school several times a week.

Hållbarhetsredovisning enligt GRI:s riktlinjer : En studie av två svenska statliga företag

What impact and effects are created by the placement of an international ranking? Could it be that a top rank is detrimental to an entire country's efforts to fight corruption?This bachelor thesis in political science is about Swedish corruption. In essence, so questioning the Transparency International's indexed rankings that placed Sweden in third place. Issues concern since if the third placement has created nonchalance and a careless mentality in Swedish government and in particular in the municipal operations. Research results show that Transparency International's rankings have low validity and low reliability and that the government is not acting sufficiently to prevent and fight corruption.

Journalistik 2.0 : Om journalistens upplevelse av medborgarnas inverkan på tidningarnas innehåll

Title: Journalism 2.0: About the journalist's perspective on citizen participation and its influenceon the news content.Purpose: The aim with this study was to examine whether, and if so how, professional journalists experience that the production of news has changed as the media development has progressed and the citizens opportunities for active participation in this process has potentially expanded.Research questions:Does professional journalists experience that the opportunities for citizen participation in the news making-process has changed with the spread and accessibility of new media- if so, in what ways?Wheatear professional journalists experience that the relationship between themselves and their news sources has changes with the spread and accessibility of new media?What consequences can an empowerment from citizens have on the production of news and on the professional role of the journalist?Theory: This essay is based on theories about convergence, gatekeeping, agenda building, participatory journalism, news sources and the journalistic profession.Method: The survey is based on ten qualitative interviews with ten professional journalists, eight reporters and two web editors from the newspapers NWT and VF.Results: The results of this survey shows that the citizens? opportunities in influencing the production of news has partly changed. The journalists do not experience that citizen participation affects their professional role. Citizens have always had an impact on the production of news but new technology offers citizens and journalists new channels that facilitate the communication and interaction. The gatekeeping process is protecting the decision-making role of the journalist, which restrains citizen participation.

Solvärme till Östersunds Rehabcentrums terapibad : Förstudie av förutsättningar för, - och lönsamhet med, solfångare för att värma terapibadet

This report treats whether it is viable to invest in solar heating to heat the therapy pool at Östersunds Rehabcentrum. The rehab center is owned by the county council of Jämtland and is located on Solliden in Östersund city. The solar heating where supposed to be a complement to the district heating that was heating the pool in the current situation. Later, it however showed that this was not the case. The pool is currently being heated by a radiator circuit that is being heated by the district heating.

The Instant Generation : - hur ser ungdomars attityder till fildelning ut?

Abstract:Title: Engelska (Svenska)Number of pages: 40 (47 including appendix)Author: Carl StrandTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The purpose of this essay is to analyze how young people, in the ages 18 to 25, relate to the subject of file sharing, and what their attitudes to this phenomenon are. I aim to describe how they use file sharing, their knowledge about it, how their usage have changed due to the new copyright law, what their stands are on the question of resource control and management on the Internet, and what they think of the future of file sharing.Material/Method: The method being used is a qualitative focus group interview model, used to investigate how young people look at the subject of file sharing. The results of the interviews is then applied to a theoretical framework based on thoughts of Denis McQuail, Lawrence Lessig concerning creativity, copyright, resource management and file sharing on the InternetMain Results: My conclusion is that the widespread file sharing habits of young people is not only caused by the temptation of getting free stuff, but of the lack of commercial and legal alternatives. Youths are willing to pay for media if the distribution is superior to the illegal file sharing alternative. They are a generation of young people that has grown up in a society where the tendency in many fields has been to make everything faster and more effective.

Diabetes : En studie om informationsbehov och informationssökning kring sjukdomen

The aim of this study has been to examine how people with the chronic disease diabetes are seek-ing information about their disease. The study also look at the sources, which are mainly used, and the information behavior of the participants in this study. Especially in diabetes health care the idea of empowerment is central, which means that the patients need a lot of information to get know-ledge and become empowered. The study also examine the public library as a resource of health information, and for that purpose an examination of the OPAC catalog in two public libraries has been done, using the word ?diabetes? to illustrate the literature and other medias related to di-abetes.

Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

Reglering av naturgasdistributörer : En undersökning av benchmarking på marknaden för naturgasdistribution

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

Farthinder med förhinder : om acceptans

A great amount of todays drivers? are constantly exceeding the speed limits on the roads. As a consequense of this, a large number of speed redusing devises, for example speed bumps, has been built around the country. As reports in local medias point out, the acceptance for these types of speed reducing devises, differs and there are many thoughts about location, construction and effect on the traffic safety. This paper approaches the complexity of these problems from the drivers? point of view, based on literature studies and a questionnaire. The goal is not to argue for or against speed reducing devises, but to try to find the source of annoyment and how to proceed further. Some of the problems turned out to be easy to fix, for example porly marked speed bumps.

Validering av glidande statorfötter på Hissmofors G6 och G7

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

Mäktig eller osynlig : En diskursanalys ur genusperspektiv om hur maskulinitet tolkas och värderas i genusmedvetna texter och i museers utställningar

The survey aims to problematize masculinity in the exhibitions of the museum.  In what way is masculinity interpreted and valued in exhibitions? What is the attitude towards masculinity in gender oriented museological texts? This study investigates in which way masculinity is written about ? how interpretations of masculinity emerge in the texts and what consequences this may have.The survey is based on the method of discourse analysis and the material is processed from a gender perspective. The source material consists of museological texts dealing with the topic of gender and museology, which also is the core material. A complement to this is a selection of exhibition catalogs from museums as well as reviews which are also based on art exhibitions. The main point of the source material consists of the museological texts.The survey highlights that the gender-conscious museological discourse understands, interpret and evaluate masculinity on a more or less given regulatory framework.

NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
