Cross-Language Information Retrieval: En granskning av tre översättningsmetoder använda i experimentell CLIR-forskning.
The purpose of this paper is to examine the three main translation methods used in experimental Cross-language Information Retrieval CLIR research today, namely translation using either machine-readable dictionaries, machine translation systems or corpus-based methods. Working notes from research groups participating in the Text Retrieval Conference TREC and the Cross-Language Evaluation Forum CLEF between 1997 and 2000 have provided the main source material used to discuss the possible advantages and drawbacks that each method presents. It appears that all three approaches have their pros and cons, and because the different researchers tend to favour their own chosen method, it is not possible to establish a "winner approach" to CLIR translation by studying the working notes alone. One should remember however that the present interest in cross-language-applications of information retrieval has arisen as late as in the 1990s, and thus the research is yet in its early stages. The methods discussed in this paper may well be improved, or perhaps replaced by others in the future..
Tjejgrupp - stärkande eller problematiskt kollektiv? : En analys av erfarenheter och minnen från feministiska tjejgrupper
This essay investigates the results of participation by teenage girls in feminist groups, the so called girl groups. These groups are descendants of the awareness-raising groups of the 1970?s feminist movement. The essay assumes the relevance of theories of heteronormativity and performativity, as well as theories surrounding two different ways to organize girl groups. It is done either through the Pippi-feminism, named after strong independent book character Pippi Longstocking, or through the collective empowerment feminism.
Arbetsrelaterad stress inom äldrevården : Anställdas upplevelser enligt Theorells krav - kontrollmodell
Abstract The main purpose of this study was to investigate if and how the employees in elderly care experience stress and which underlying causes they understand to be important in their work situation. The purpose was also to investigate whether Karaseks and Theorells demands and control models could be used to explain the employees feelings of stress and to see in which categories the participants are in. Furthermore, the purpose was also to understand the participants work situation and to describe the factors and remedies the employees perceive to contribute to the stress levels at their workplace. 81 questionnaires were distributed at three different locations, two of which were in Ronneby and one in Örebro. 56 people answered the questionnaires.
Tillfällen då hemodialyspatienter anser det vara svårast att undvika vätskeintag : En empirisk studie
The aim of this study was to investigate which situations haemodialysis patients consider as the hardest for avoiding fluid intake. The data collection was performed with a questionnaire which was distributed to haemodialysis patients who fulfilled the inclusioncriteria. Of 158 haemodialysis patients 103 haemodialysis patients chose to participate in the study. The participants were chosen from different dialysis centres (n=12) in north and south of sweden, excluding the middle of Sweden. The questionnaire that was given out consisted of 32 situations, the response format included nine alternatives, that included different kind of difficultes.
Automatisk räkning med monokrom visionsteknik
The use of vision applications are growing and the demand for integration and connectivity with other industrial automation control devices is increasing. Some businesses that are using vision technology follow US Food and Drugs Administration (FDA) regulation concerning audit trail. This thesis investigates the possibility to use vision technology for counting objects, achieving connectivity and to follow FDAs audit trail regulation. A market survey has been used to select suitable hardware and software to be used in the design of an application that is able to count objects and that uses standard industrial network connection i.e. OPC data access and Microsoft?s .NET components over Ethernet.
Hivprevention - en rätt(vis) fördelning av statsanslaget? : Diskurser om homo-, bisexuella och andra män som har sex med män
The purpose of this study is to explore how different discourses about risk linked to HIV prevention is likely to affect the decisions on the distribution of state funding for preventive activities aimed at 'men who have sex with men' (MSM). This by making qualitative interviews with principals that have an impact on this decision. Using a discourse analytic approach, based on both theoretical and methodological foundations, I investigate the discursive constructions of risk of HIV linked to certain groups and behaviors. MSM is found in the material placed into two different formations of groups, on one hand by the behavior on the other hand on the basis of identity. The identity position is organized discursively from a ?victim? position while MSM provides an "operator" position.
Kunskapslyftet och Huvudbiblioteket i Linköping - Hur upplever de kunskapslyftsstuderande biblioteket och hur har bibliotekariernas arbetssituation påverkats?
The aim of this study is to examine how the adult students in the Adult Education Initiative called Kunskapslyftet, experience their use of the Main Public Library in Linköping and how the librarians experience the change in their working situation after Adult Education Initiative has started in July 1997. Methods used in the survey are interviews with librarians and students in the Adult Education Initiative. I have also distributed questionnaires to some of the adult students and studied literature that describe students use of libraries. The result shows that the students generally are satisfied with the service they get from the librarians at the Main Public Library. It also shows that what the students mostly asked for, are help to search information about a subject and to find literature in the library.
Läcksökning med penetrant ? kvalitetssäkring av
Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.
?Känner du dig välkommen?? ? En undersökning om användares upplevelser och åsikter av miljön och servicen i Högskolebiblioteket i Halmstad
The purpose of this thesis is to explore the experiences and views some users have of the library environment and services of the University Library of Halmstad. The main question to be answered in this thesis is what importance the users attribute to the library environment and services while pursuing their most recent library errand. To answer this question a study of relevant literature on the subjects of library environment, library services and user-surveys in other academic libraries was carried out and a questionnaire was distributed to 22 respondents in the process of visiting the University of Halmstad Library. The literature background and the results of the conducted study were interpreted and discussed and led to the following conclusions: 3 respondents encounters with the library environment and its services were negative in part and thus their experiences and views were relevant to the completion of their library errands. The other respondents? encounters confirmed their overall positive earlier experiences and views of the library environment and its services, but had no real concrete significance for the completion of their library errands..
Nyttan av Web 2.0 i en CRM-kontext
Web 2.0 is a relatively new concept which has made significant progress on the Internet. More recently, corporations as well have begun to get use of the different types of applications that are assigned to the Web 2.0. Organizations are primarily interested in making use of Web 2.0 in two areas: inside the company to increase efficiency and productivity, and from the organization to the customer to improve revenue and customer satisfaction. We have chosen to take a closer look at this last area, as can be seen as a CRM context. Our interest is to investigate how such a context may change by implementing some kind of Web 2.0 technology.
Implementering av affärssystem
I dagens hårda konkurrenssituation krävs det mer och mer av företags informations-system. Detta gör att fler och fler företag väljer att implementera ett integrerat affärs-system. Integreringen gör att företag får en enhetlig systemmiljö för hela företagets informationsbehandling. Implementeringen är dock en kostsam och tidskrävande process (Ekstrand, 1998). Mitt arbete behandlar frågeställningarna om varför företag väljer att implementera ett affärssystem, hur implementeringen förlöpte samt hur affärssystemet fungerar när implementeringen är färdig.Bland de företag jag vände mig till så var den främsta anledningen till att företag installerar ett affärssystem att systemen är omfattande och integrerade.Jag kom även till slutsatsen att det nästan är omöjligt att genomföra en implementering av ett affärssystem helt smärtfritt.
Vilka attityder unga män och kvinnor på gym har till dopning och kosttillskott : En enkätundersökning i Gästrikland
The aim of this study was to investigate which attitudes young men and women at gym have to doping and supplements in Gästrikland. Method: This study is based on a cross sectional study design where a quantitative approach was used by 60 questionnaires which were distributed at different gyms in Gästrikland. Result: It was found that the majority had a relative negative attitude to doping, those who used supplements had a slightly more positive attitude to some of the statements compared with those who did not use supplements. Overall, the results showed a positive attitude to supplements. Compared with previous studies, it was found in the study that a smaller proportion didn?t agree that it is up to each one to use doping substances.
Self-organizing maps ? en atlas över informationsrymden
The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.
Naturlig haptisk kraftåterkoppling från volymdata
As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.
Emotionsreglering och stämningsläge som faktorer för högt och lågt risktagande i beslutsprocessen
The purpose of this thesis is to investigate the ways in which emotion regulation and mood affects risk taking when it comes to decision making competence. Emotion regulation is an essential part of the attachment process, the development of an autonomous self and functional stress coping systems. Research indicates that there is a relation between a distorted emotion regulation and some psychological disorders like depression, PTSD, anxiety disorders and borderline (or instable emotional personality disorder). There is a definite need to analyze the relation between emotion regulation and decision making competence since it is relatively unexplored. A digital questionnaire was distributed amongst the participants.
