This thesis deals with query formulation in full text retrieval. The variables studied were query expansion and query structur[INS: e :INS , and the aim of the thesis is to study their co-effects on retrieval performance in a probabilistic system. The expansion was made with synonyms, and the structure by expressing facets and phrases. The study was performed using QPA, Query Performance Analyzer, which includes InQuery retrieval system and a sub-collection of TREC documents with its topics. The measurement used was precision at 11 DCV points.

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

In today?s business environment, cost-cutting practices such as downsizing and layoffs remains a widespread phenomenon. Although, the understanding of the effects that these practices has on the remaining individuals, defined as the survivors, is poor. The focus in this paper is therefore to examine how survivors of layoffs can be affected on an individual level, and by what causes.The study was conducted using open-ended, qualitative interviews with three individuals with different experiences of layoffs. The empirical data was analyzed by extracting quotations from the interviews.The study found that layoffs affected the morale and attitude towards management of the individual, and that perceived justice and uncertainty are two causes of negative effects from layoffs..

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Aim: The purpose of this study is to increase the knowledge around the location?s importance when rent setting office premises. Furthermore, I want to get broader knowledge about the real estate market as a whole when since it is of current interest.Method: The study is performed with the aid of qualitative interviews on persons with experience of office premises in Stockholm city. Theoretical dates mainly have been gathered via literature and the Internet.

The purpose of this master thesis is to investigate whether exhibitions and silent pedagogy can be used to develop more inspiring environments in the public library. Silent pedagogy is a term from the field of museum education describing the silent communication with visitors that takes place in exhibitions through introduction and orientation, layout and installation, as well as signage. In the 1980s, articles in a Swedish library magazine discussed the pedagogical importance of library exhibits and how they make the patrons aware of the library?s resources. This led us to museum education and a desire to investigate whether its theories were transferrable to the library context.

The purpose of this study was to examine the impact of the parent training The Incredible Years in clinical settings. The study included 33 families in clinical practice. There were two parts to the study; a main part with a before and after measurement, and a follow-up study on 12 children one year later. On baseline the children (3-9 years) as a group were on the borderline clinical range, (M = 61.8), with 70 % of the children in the borderline or clinical range. The childrens emotional and behavioral problems were measured with Child Behavior Checklist (CBCL).

The purpose of this study has been to examine how female probation officers construct the concept of women who commit crime. This have been done by examining how the probation officers describe the phenomenon from their own point of view, how they perceive society's view of the phenomenon, how they describe the women's self-images and how their own perceptions affect the treatment of these women. To fulfill this aim the study is based on qualitative interviews with five female probation officers. We analyzed their statements by using Gender theory, Goffmans stigma term and Beckers deviant term. The result of this study shows that women who commit crime are described more as victims than offenders and that they are constructed as deviant in two ways; both in relation to the law but also in relation to their gender.

The basis of road investments is to minimize the transportation cost. The forest industry wants roundwood to be available during the whole year. One way of determine which road to invest in is to do a cost/benefit calculation. SCA Forest lacks a uniform approach to determine the utility of a road investment.

The aim of the study was to examine prerequisites for the changes that are taking place within working with Intimate Partner Violence in Västra Hisingen (a municipal district in Gothenburg, Sweden). My research questions concerned incentives for the new features, their practical consequences and prerequisites for implementation.

The work material has then been analyzed using Implementation Theory, Human Service Organization Theory and theories on breaking up. The study showed that all respondents were motivated to perform the changes, but also that there were significant differences between the groups? conceptions of what implementation demands, and of the organizational support today.

The Swedish retail business has been characterized by a small number of ruling distributors. These distributors have been affected negatively by the internationalization which has made it possible for international distributors to establish their stores in the Swedish market. These international distributors are focused on low price stores. Their establishment on the Swedish market has led to a decrease in market shares for the Swedish distributors, which has damaged their profitability. Another change that has affected the Swedish distributors is that the behavior and needs of the customers has changed.
