The purpose of this study is to examine the experiences and perceptions of children`s librarians regarding floating collections in public libraries in Gothenburg. In focus for the study are the experiences and perceptions that exist among children`s librarians when it comes to children as library users, the librarian`s working tasks and the professional role as a librarian. The empirical material has been collected through semistructured interviews with six children`s librarians. The material has been analyzed twice. The first analysis has been conducted through qualitative content analysis.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

The chow-chow breed is considered to have a low fertility and this report is an in depth study of the reproductive functions of this breed in Sweden. Only 53 % of the Chow-chow matings results in litters. Previous studies of other breeds in commercial kennels shows mating results around 85-90 %, but this has not been investigated in hobby kennels and most Chow-chows which are bred from in Sweden, are kept as family pets. Contrary to most other breeds, Chow-chows show a seasonal reproductive pattern and most litters are born in the autumn. The influence of the month of mating on pregnancy rate and litter size was found to be not significant, but can be considered a trend. Thirty-nine females with previous known fertility problems where studied. Some of them had reached puberty extremely early, at an age between 4-5 months, and many of the bitches showed great fluctuations in intervals between oestrus cycles. Some of the females showed abnormalities such as very short oestrus intervals of only 2-3 months, probably without ovulating.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

Children and teenagers of today have grown up with digital media. According to Olle Findahl's report "The Swedes and the Internet" (2009), adults as well as children are online more and more. Our experience is that at many workplaces as good as everyone use computers and everyone is expected to have digital skills. However at most schools the reality is far from this. According to Findahl's report from 2009, 99 percent of all pupils (in Sweden) have access to computers and Internet, yet it is rare that they get school assignments where the use of Internet is acquired (Findahl 2009).The purpose of our paper is to understand how digital media can be used as a resource for learning, through the perspective of young people.

According to old european tradition the ideal national state has a unified people, but in reality practically all states has one of several minorities that to a smaller or greater degree differs from the majority. One such minority that have been present in many countries and managed to avoid becoming completly assimilated are the jewish people. Their dream of a state of their own eventually lead to the founding of the state of Israel where they themselves are now in majority. The purpose of this report is to study how the jews historic experiances has affected the political parties in Israel, how they choose to meet the ?challenge? of their own minorities och whatever they treat different minorites differently.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

This bachelor thesis? purpose is to investigate how purchase librarians work with foreign language collection management. Since about 15% of the citizens of Sweden are born abroad or have a foreign background, the subject of investigation becomes relevant because it touches a wide user group of the public library.Interviews were conducted with four librarians responsible for purchasing of foreign literature. The purpose of these interviews was to investigate which underlying strategies and thoughts are used as a basis for purchasing.Since the library act does not include guidelines regarding the content of the foreign literature collection, how is the literature chosen and to what purpose?As a theoretical framework a self-developed model was used to categorize the foreign literature into its different functions.

Wallyfy is planned to be a social webmagazine with a focus on good content, with a quality check and moderation of the published content. The author of the study provides Wallyfy with thoughts and ideas about the website content and functionality. The main problem of the study was to explore what makes good content in social media for the potential users of Wallyfy, also using this insight to provide Wallyfy with directions for making decisions regarding both functionality and content. The theory of the study is being used as a starting point for understanding the phenomenom social media and to easier grasp the problem. The method of the study is based on user- centered thinking in design, where the author seeks to understand the participant?s emotions, values and dreams.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

Samlingar finns även i våra nordiska grannländer Norge, Finland, Danmark och Island. I Sverige har ett insamlingsarbete av rabarber pågått under åren 2002 och 2003 för att komplettera en äldre samling.

Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

Background. Immunohistochemistry is a useful method in the differential diagnosis between pleural mesotheliomas and metastatic adenocarcinomas in the pleura. Cytokeratin 20 and 7 have been used successfully as markers in studies determining primary location of adenocarcinomas from metastases. The current study is a complementary research of archived paraffininbedded material of cases with cancer origin. This study contributes a bigger statistical material that may facilitate the search for unknown primary site of adenocarcinoma by identification of metastatic cells in the pleura.Methods.
