This paper presents a study that evaluates the performance of stock recommendations issued on Swedish stocks during 2003. The selection of recommendations in this paper originates from banks, major brokerage firms and financial press located in Sweden. The total of 171 recommendations consisted of 99 buy recommendations and 72 sell recommendations. Forecast revisions presented in this paper suggest that Investment managers have no ability to predict performance winners, nor do their forecasts in general have any significant impact on stock prices. A mere 50 percent of the recommendations in this revision had a weak ability to outperform their benchmark indexes as in other similar revisions.

Today an increasing number of schools and organizations are investing in so called Learning Management Systems. Researchers disagree on the pedagogical value of these tools. Some mean that Learning Management Systems cement old-fashioned behaviouristic teaching practices; others mean that the systems provide good opportunities in supporting learning in a socio cultural perspective. The aim of this study is to reach better understanding and increased knowledge of how the introduction of a Learning Management System influences the role of the teacher and how the learning is organized. We have conducted two case studies.

The management at the City of Stockholm?s Sports Department have problems. During recent years several IT-projects have been launched but results are worse than could have been hoped for. The projects are generally perceived as being too expensive, too time consuming and not to have delivered the expected results. This thesis aims at giving the City of Stockholm?s Sports Department theoretically based advice on how to improve their management of IT-projects.

The care for the elderly in the municipalities has recently seen the need for a formalized system for quality assurance. Under increasing demands for monetary efficiency while bound by law to retain acceptable standards in health care, there is need for efficient and at the same time quality-assured management. The municipalities often solve this puzzle by introducing systems and standards influenced by theory-clusters such as NPM (New Public Management), TQM (Total Quality Management) or other quality management theories.This essay focuses on how the public administration in the municipalities defines quality and designs and implements system for formalized quality assurance. Our basic view of organizations is institutionalist and our theoretical framework includes theories about quality, NPM and TQM..

In this essay I analyze the performative aspects relating to Marina Abramovi?'s The Artist Is Present, which took place in spring 2010 at MoMA in New York, from the context of the artist and work, institution and documentation. In this performance work, for the duration of the exhibition, Abramovi? sits completely still opposite another chair where anyone from the audience may sit. The art arises through this participation.

Vårt syfte är att skapa en djupare förståelse och klargöra för användningen avbegreppen management och ledarskap i praktiken. Med hjälp av begreppens innebörd kan vi som forskare få möjligheten att framföra hur begreppen används praktiskt. På så vis kan vi se om teorin reproduceras i praktiken. Vår uppsats visar att intervjupersonerna tror att de utövar ledarskap, men att det inte kan utövas i praktiken. Detta har sin grund i den tvetydighet som omger begreppet ledarskap och företagets organisationskontext.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.

From an early age kids learn that their good performance and efforts will be rewarded. Unfortunately, not all leaders in the media industry are rewarded or given the same opportunities to exercise their communicative leadership, according to studies in media research. The aim of our study is to highlight female managers' experiences of their communicative leadership in the Swe-dish media industry. This study was based on qualitative interviews with four female respondents in management positions. The core of the study concerns female communicative leadership and interpersonal communication.

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.
