This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

I Sverige och utomlands har man på senare tid sett framväxten av ett nätverk av s.k. Science Centers (SC). Dessa SC har som viktigaste syfte att öka besökarnas naturvetenskapliga intresse. När det gäller elever från högstadiets senare år kan detta ökade intresse för naturvetenskap t ex visa sig i form av en ökad benägenhet hos eleverna att söka sig till ett naturvetenskapligt inriktat gymnasieprogram.Vi har utvecklat och använt en enkät-baserad metod för att undersöka den påverkan på elevers intresse för naturvetenskap som ett besök på SC har. Enkäten är lämplig att användas för elever från grundskolans senare årskurser.

AbstractThe real estate sector is today responsible for 40 per cent of the total amount of energy consumption within the members of the EU. All over the world there are collaborations within research and projects to find ways of reducing the amount of energy consumed by the real estate sector. In Sweden, a directive from the European Union has posed demands on authorities as well as on the private sector to reduce the amount of energy consumed by new building constructions. Together with the directive from the EU there are also new requirements and demands from Boverket for the real estate sector.  These requirements mostly concern the energy consumption of kilowatt-hour per square metre and that the consumed energy also should be renewable.  The aim of this study is to explain what kind of value municipalities experience in using certifications and environmental investments for new and existing buildings. Within the chapter theory, essential areas are described such as; environmental certification systems, economical viability, proceeds connected to building green, difficulties with building green, the performance of green buildings when affected by the behaviour of tenants and customer value.  The following chapter describes the methodology with which we have conducted this study.

The purpose of this paper was to investigate what young behavioral science students, born in the 1980s, think is important in their future work life. The purpose has also been to investigate what attitudes the behavioral science students have towards their future work life, and what place work has in the young behavioral science students lives. After clarification of above, the aim has also been to compare the results with former research. Thereafter the purpose has been to investigate whether traditional work motivation and job satisfaction theories are applicable for young people today. The empirical material is based on interviews with six women who study behavioral science at various levels.

Municipalities in Sweden are responsible for physical planning by developing a general plan. This plan contains intended land and water use for the area. This study aims to investigate the level of integra­tion of environmental issues in the general plan of Arboga municipality and also how well adapted the municipality is for climate change. Further on, the study intends to examine the focus of the gen­eral plan and at what rate the national environmental strategies are implemented in the local physi­cal planning of Arboga municipality. Methods used for this study are interviews and reviewing of the general plan itself and other key documents.

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.

Knowledge of ecological processes are a basis for the understanding of important environmental issues. Through qualitative interviews, 8 preschool class pupils have replied to questions concerning the concept nature, disintegration and environment. The aim of this survey was to examine what attitudes and knowledge children with different pedagogical background have about the nature and the environment.The result of this survey in whole demonstrates that all pupils have good and equivalent knowledge of the nature and the environment, independently of their different pedagogical backgrounds. A difference was however that children that have background from ?I Ur och Skur? (a Swedish outdoors preschool program) know the names of all small bugs that were in the survey.

This Batchelor?s Thesis concerns 20 points at the MDA-program (People, Computers and Work) at Blekinge Institute of Technology in Ronneby, Sweden. 10 points concerns Computer Science and 10 points Human Work Science. The thesis is about the process of starting a new department of Blekingesjukhuset [Blekinge Hospital] in Karlshamn, Blekinge called Sjukvårdsrådgivningen [Health Care Advice Bureau]. The thesis starts with a description of the ethnographical methods used, followed by the process of establishing the department. In this new department, the nurses are using a computer based system called Teleråd, developed by TietoEnator. The thesis takes up the issues of how the department uses this system today and concerns what ?user-friendliness? is.

Detta examensarbete är utfört på Helsingborgs Dagblad AB i Helsingborg. Examensarbetet omfattar en analys ur kvalitetssynpunkt av HD:s material-, energi- och transportflöden, dess påverkan på miljön, kopplingen mellan HD:s tre kärnvärden och vikten av ett strukturerat miljöarbete samt ett antal förslag på fortsatt arbete. HD:s materialflöden består främst av material för tryckningen men även en hel del elektroniska apparater. Ett stort antal datorer och annan kontors-utrustning står på dygnet runt, året runt vilket orsakar onödigt stor energiförbrukning. HD:s verksamhet är beroende av transporter, både av material och personer.

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Sustainability and the role of companies in terms of emissions and environmental impact has become increasingly more relevant. In 2014, the EU decided to introduce the NFRD, a directive that makes it mandatory for companies that meet the requirements to report on sustainability. This thesis aims to examine how four large Swedish industrial companies report about sustainability in connection with the introduction of NFRD, looking at the years 2015 (2014), 2017 and 2022 from an environmental viewpoint. Furthermore, the study also intends to investigate how the companies write about their sustainability work, as actual achievements or what they have ambitions to do in the future. In order to carry out the study, a content analysis with elements of both qualitative and quantitative features has been used called the CONI method.

The forests in the unique archipelago of the Baltic Sea is housing many and high values. For the resident population, which has a central role in sustaining a living archipelago, the forest can contribute to the outcome. The forest also contributes to turn the archipelago into one of Sweden?s most attractive recreational areas. Furthermore, these forests exhibit very high environmental values, and they are an element in the traditional cultural landscape.

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
