I dagens samhälle spelar informationssystem en viktig roll i de flesta företag och organisationer. Informationssystemets uppgift är att tillgodose och hjälpa användarna med information och informationshantering samt att leda till en effektivisering.Arbetet med att utveckla databaserade informationssystem är problematiskt och systemutvecklingsprojekt överstiger ofta budget både vad gäller tid och pengar. Återkommande problem är att systemen inte gör vad användaren vill samt att systemen inte utnyttjas till full kapacitet. Svårigheten med kravhanteringen är något som anses vara en orsak till misslyckandena.Den viktigaste informationskällan för systemutvecklarna då det gäller att ta reda på systemkraven är användarna. Då användarna spelar en viktig roll i kravhanteringen, vilken i sin tur spelar en viktig roll i systemutvecklingsprocessen, är detta ett intressant problemområde.Denna rapports fokus ligger på hur användarna ser på kravhanteringsprocessen.

Syftet med studien är att få kunskap om hur rektorer definierar och värderar resurser. Genom kvalitativa intervjuer och ett rangordningsformulär har rektorers syn på olika former av resurser kartlagts kopplade till elevers studieresultat och lärandemiljö liksom resurser som eventuella hinder. Studiens resultat pekar på att resursbegreppet bestäms av vem, var och när det definieras. Då samtliga grundskolerektorer i en kommun rangordnar är det resurser av mer abstrakt/själslig karaktär som värderas högt oavsett kön. Högst värderas personalkompetens och den psykiska miljön, vilka båda, enligt Herzbergs tvåfaktorteori, är motivationsfaktorer som ökar arbetsprestation och tillfredsställelse och bör gynna eleverna.

In nature settings people often experience positive emotions. Litterature and theories about the positive effect of nature on humans are largely based upon visual impressions and aesthetic preference. The purpose of the present study is to examine how visually impaired individuals that lack visual impressions experience nature. The background is about what it means to be visually impaired and what it is like to be visually impaired in a nature setting, followed by a presentation of the five human senses and about stimulation of senses in healing gardens. That is followed by theories about the health promoting effect of nature, about why nature and therapeutic gardens make people feel good. After that theories about experiences and relations with settings are presented.

The purpose of this master thesis is to investigate the understanding of children's librari-ans regarding children's needs and preconditions in a library context and based on devel-opmental psychology and information seeking theories. The children's perspective is said to be the guiding star in the children's library and the thesis also aims to study the chil-dren's perspective as defined by children's librarians.The master thesis is a qualitative study based on interviews with children's librarians working at major public libraries. Observations of the children's libraries in the study have to some extent been performed.The study reveals that children's librarians are fairly knowledgeable about children but do not to a full extent use that knowledge into adapting the library to children and their needs. The children are not contributing to the adaptation of the library to any extent as there are few routines for that matter. In society in general children are on a regular basis represented by adults and their perspective on children and children's needs, which may differ from the perspective children have on their own lives, and the same is applicable for the children's library.

This bachelor thesis explores the conditions for a harmonized EU gender equality policy. Recently the maternity leave directive has been introduced by the European commission and seeks to improve the conditions for pregnant workers. The controversial subject of this maternity leave has illustrated many of the problems connected to the development of a social dimension in EU. First of all, the debate concerning the maternity leave directive in the European Parliament has shown that both sides in the parliament seem positive towards creating legislation in this matter on EU level. However, parties at the right tend to disagree to many of the amendments in the proposal, such as the maximum entitlement.

Syfte: Att identifiera vilka aktiviteter som var vanligt förekommande på särskilt boende utifrån litteraturen och vilka effekter de hade på äldres livssituation.Metod: Studien genomfördes som en litteraturöversikt och artiklar söktes genom databaserna Pubmed, CINAHL with Full Text och Academic Search Elite. Studiens resultat innehåller 18 antal artiklar.Resultat: Olika sociala och fysiska aktiviteter hade en positiv inverkan på livskvalitén, men även på de boendes upplevelser av ensamhet. Deras fysiska förmåga förbättrades också i form av att de lättare kunde utföra aktiviteter i dagliga livet (ADL). Fem olika kategorier med aktiviteter skapades. Dessa var trädgårdsprogram, fysisk aktivitet, interaktion med djur, sociala aktiviteter och musik.

The purpose of this thesis is to describe and analyse the road towards a modern library in the southern archipelago of Gothenburg between the years 1943 and 1976. The archipelago consists of about thirty smaller and larger islands, of which seven are inhabited throughout the year. Styrsö and the surrounding islands composed a municipality of their own until 1973. In January 1974 it became a part of the municipality of Gothenburg, this is also the year when the only bridge in the archipelago was ready to be taken into use, between Donsö and Styrsö. There is no bridge between the mainland and the islands.

In studying the art of Counterinsurgency Warfare we are usually inclined to the reading of several books regarding this matter. Because of this some writers have the power to influence the minds of the reader. This can be of great benefit since it enables information sharing and for the reader a chance to learn from the triumphs, but also mistakes of others. However each writer is the creation of the time and context under which he existed. Because of the wheel of time certain things change, and because of the context a myriad of factors came into play affecting the outcome and product of the doings and thoughts of that specific occurrence.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

The purpose of this thesis is to draw a picture of pedagogical work at the senior level with a critical perspective of information and media. As a method for gathering material for the analysis, a case study was made with qualitative interviews together with documents that describe the case. Relevant literature for the subject has been used as an introduction and as a theoretical basis. The literature concerns subjects such as a childrens relation to media, the schools intructions, the role of the school library and some theories regarding learning. The conclusion is that the respondents focus on conversations and reflection regarding the sources of information and its use, and that the childrens adaption of the material is an important factor in teaching.

The aim of this essay is to study diaries and letters from Swedish soldiers during the Great Nordic War, more specifically those written during the campaign 1707-1721 against Russia, in search of religious coping and religious parables. The theoretic framework is evolved around Kenneth Pargament?s theory about religious coping, and Ana-Maria Rizzuto?s theory about object relations. The method used can be described as hermeneutic.The questions at hand were:- How did Swedish soldiers during the war against Russia relate to God, and express image of God and religious concepts?- Did the soldiers express themselves in terms of spiritual coping and in that case to what extent?The conclusions were that the soldiers used religious coping as a method of survival.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.The aim of the thesis is to identify some areas of possible improvements of the company?s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company?s information retrieval process are insufficient and incomplete.As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified.
