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.

Botulism is a serious disease with high mortality that can affect horses. Due to this about 20-30 percent of the horses in Sweden are vaccinated against botulism. The purpose of this study was to see how common botulism is in the Swedish horse population and to se if a connection between feeding with haylage and botulism could be seen. In addition to this, the study aimed to find how common vaccination against botulism is among Swedish horses and on what grounds the diagnosis botulism is made. Medical records of horses being diagnosed with botulism at all the major large animal hospitals in Sweden between 1995-2005 were searched. In addition to this the database where general practitioners report their cases as well as the cases with botulism reported to the insurance companies were included. The results of this study show that only 0,03 percent of the Swedish horse population has been diagnosed with botulism during the time period this study covers. In all the cases included in this study the diagnosis was made based on clinical signs and in none of the cases verification by isolating the toxin was possible. In all cases where forage is noted in the journals the horse has been feed haylage which indicate that there is a connection between the use of haylage and botulism. Three horses died despite being partially vaccinated against botulism type B which indicate that a correct vaccination has to be done before the horse get any protection or that the correct diagnosis was not botulism type B..

Aim: The aim of this study was to examine and explain the various methods available to rate the erosion damage, and on which teeth and tooth surfaces of erosion damage mostly occurs in children and adolescents.Method: A literature review was conducted, based on 15 scientific articles that have been reviewed, evaluated and analyzed. Articles were searched for in the database PubMed.Result: Six of the articles used the TWI (tooth wear index), which is an index to diagnose the tooth wear in the primary and permanent dentition. Eight articles used other indices as they considered that the TWI was not sufficiently developed to register the degree of tooth wear on some teeth. Tooth wear in the primary dentition occurs most often in the canines and incisors. Tooth wear in the permanent dentition was found in the literature to be mostly occurring on the occlusal / incisal surfaces of all teeth and tooth surfaces.LyssnaConclusion: There is no common index in the articles but many of them use the TWI.

The web has made an incredible amount of unorganized information available to anyone. There are search engines that help us structuring the information, but it is still difficult to find what you search for on the web. The purpose of this master's thesis is to investigate whether the already existing techniques for automatic indexing are suited for the new information retrieval context on the web and how the choice to support these techniques, or not, affects the search results. This is examined through a literature study on automatic indexing and other related concepts, such as information retrieval and information searching on the web in order to get a theoretical frame to the work and by an observation of the search engine HotBot to approach the purpose of the thesis. The observation is carried out by searching HotBot's database and investigating the search results in order to try to identify patterns that can reveal something about how HotBot's automatic indexing is done.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

Aim: Auditors objectivity is an obvious part of auditing, but there is doubts and hesitation in society today because of the corporate scandals that have occurred in recent years. Several researchers suggest that auditors actions and behaviors is connected to the ethical climate within the organization. A relationship that also affects auditors objectivity and independence. This thesis aims to investigate how the ethical climate influence auditors choice of relationship to their clients, by choosing a relational and close relationship or a transactional and distanced relationship. And if the client approach have an effect on the auditors objectivity.Method: A survey was conducted among 232 certified accountants in Sweden.

The aim of this thesis is to use the bibliometric method author cocitation analysis (ACA) and investigate the cognitive structure in a research field, which is called the intellectual base. The research field in this investigation is social psychology. The main question is: what is the nature of the cognitive structure, which contains of the intellectual base. This question is divided in two sub questions: ? Which are the most prominent authors in the research field? ? Which sub areas, based on groups of the most cocited authors in the research field, can be identified?An investigation with ACA is used to describe the general experience of consensus of later authors in a research field.

The town of Karlstad has a long term project called Vision 100 000 which aim is to increase the population towards 100 000 inhabitants. This will of course put a strain for the town?s energy distribution grid. This is a work about trying to predict the grids power usage would be for the next five years if the city building plan is finalized. Those predictions are mainly going to be done through calculations with a database program called Facilplus and by checking the measured history of power usage per hour on certain selected customers by the program CustCom.

AbstractThe term aftercare is largelyexplained by means of the contextual and ideological conditions for treatmentwhich are to be found in juvenile care facilities. The development of the livesof young people who have been placed in care facilities is dependent ontherapeutic relationships, professional separations, continuing follow-ups andan even transition from control to autonomy. The aim of this study was toexamine the steering mechanisms behind the execution and planning of aftercareat a youth facility for care or residence. The aim was further defined throughthe specification of the following questions: 1. How are the concepts ofresocialisation and aftercare define and delimit? 2.

The study describes six upper secondary school students? thoughts of and stories about mentors and mentorship in secondary school. The mentorship has been studied with a hermeneutic approach from a narrative pupil relational perspective, which is influenced by the phenomenological humanity perspective. The aim of this study is to describe a few pupils? life worlds and to try to interpret how they describe and explain their own behavior related to mentorship and their mentors.

The aim of this thesis has been to achieve a deeper understanding of how librarians provide adult readers with individually adapted readers´ advisory in public libraries. The focus within this context, has been to find an answer to how the librarians understand what appeal factors the readers are attracted to and what kind of reading experience the readers are looking for to be able to match book and reader.To be able to find answers to our research question we conducted eight interviews with librarians working with readers´ advisory in eight different public libraries in Skåne. Our theoretical standing point for the thesis has been that of Marie L. Radford and Cathrine Sheldrick Ross. Sheldrick Ross provided theories concerning the appeal factors of books.

Background: Diabetes mellitus is one of today's major public health problems, affecting up to 347 million people worldwide. Several studies have shown a correlation between hearing loss and diabetes mellitus. However, it is still unclear whether this correlation differs between type 1-diabetes and type 2-diabetes.Purpose: The purpose of this study is to investigate whether there is any difference in prevalence of hearing loss in type 1-diabetics versus type 2-diabetics.Method: A meta-analysis was performed based on ten studies that were identified through the database PubMed and through manual searching of references. Odds ratios for the risk of developing hearing loss were calculated in each study. Pooled odds ratios were calculated using a random effects model.Results: Pooled odds ratios indicates that both type 1-diabetics and type 2-diabetics are more likely to develope hearing loss compared to non-diabetic controls.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.
