The possible role of transmissible gastroenteritis virus (TGE) and porcine respiratory corona virus (PRCV) in the mortality of Ugandan back-yard piglets
In Uganda, small scale pig production plays a major role for households to earn a living and to secure their access to meat. Piglet mortality due to diar-rhoea-related dieseases is high. In an attempt to understand the underlying causes for this high mortality this study aims to investigate the role of trans-missible gastroenteritis virus (TGEV) and is a part of a larger project con-ducted at Makerere university in Uganda.
A complicating factor in this investigation is the porcine respiratory corona-virus (PRCV), a stabile mutant form of the TGE virus. The occurrence of this virus had shown to alter the impact of TGEV in e.g. Europe and North Amer-ica.
Kommunikation och samarbete. En studie av bibliotekariers och lärares förhållningssätt gentemot varandra gällande samarbete
The purpose of this paper has been to study the relationships and attitudes of a few teachers and librarians as to their co-operation in a combined public and upper secondary school library and to find out what circumstances there may be to exert an influence on their work. The paper has been based upon qualitative interviews with upper secondary school teachers and librarians as well as on studies of literature relating to our issue. We believe there may be different approaches to the learning process, as these are the relations and attitudes of two professions from different trades. That is why our point of departure has been Roger Säljö's theory about learning and, in our analysis, a few of Jean Donham van Deusen's ideas of joint planning and flexible timetabling. All respondents agreed that co-operation could be better, but the teachers were of the opinion that it must not interfere with their time.
Att utföra kravprioritering med kravprioriteringsmetoder - en studie om dess genomförande och hinder under
Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..
Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.
The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.
The Scientific Coach - Idrottsforskning i tränares vardag
Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008). This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.
The Impact of Special Dividend and Redemption Announcements on the Swedish Stock Market
The aim with this study is to investigate the market reactions to announcements of special dividends and redemptions in Sweden and thus if these announcements can signal information. This study is an event study, where the event is the day of the announcement of a suggestion regarding issuance of special dividends or redemptions. The abnormal returns were estimated for two samples with the market adjusted returns model, one including special dividend announcing firms and the other redemption announcing firms. The signalling hypothesis and the hypothesis of a tax induced clientele effect are the most important hypotheses for this study. The efficient market hypothesis is another theoretical base that may explain the market reactions to the studied announcements, especially the pre-announcement activities that may occur.
Att skapa ett informationssystem ? en holistisk ansats
This thesis aims to discuss how an information system and its users may adapt to each other. The main discussion is how to create an information system that is adaptable without losing its organising properties. The thesis uses a holistic approach to the topic and the areas being dealt with are information architecture, interactive information retrieval and information searching. The practical work consisted of constructing a database for Autoliv?s Research and Development branch.
Planering : fallstudie av en mjölkgård
The purpose of this paper is to give examples of different ways of economic planning and
calculation within agriculcture. My aim is to use a couple of them as an explanation of a case
from reality. My choice went to budgetsimulation and balanced scorecard since those are best
suited in this specific case.
In the information retrieval I present different instruments of economic planning like theory of
cost, budget and productcalculation. The budgetsimulation describes how to use the different
methods in a long term economic planning. The balanced scorecard is also a model of longand
short-term planning but besides the economy planning it?s also a reminder of your
personal goals.
In the model I have used a dairyfarm as a case.

Ett ?bra? intranät ? Ett framgångsrikt exempel på användarcentrerad systemdesign
We live in a stressful world and a demanding society where the ability to quickly adapt is one of the most important and most difficult challenges of today. A fairly new phenomenon called intranets has evolved to meet this challenge, however many examples of corporative intranets are stories about failures and systems with poor usability. This study focuses on how the user oriented approach to systems design affected upon a system development process of an Intranet, solely developed within a company, and how it impacts on the intranets popularity among the employees in the company. The study starts not from the literature but from a survey, which is based upon the Delphi method. Which results were used for further in-depth research about the subject, by interviewing three representatives from the company.
Plant defensive mechanisms against insect pests
This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.
?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans
Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.
Företagsbibliotek i förvandling : företagsbibliotekens tjänster i informationsåldern
A company library can only exist if it contributes to a positive result for the company. As endusers are beginning to perform searches on the Internet and have access to databases and electronic documents via their desktops it becomes important for company librarians to thoroughly think through what services should be offered to the users so that the library still contributes to the company s profit. The aim of this dissertation was to try to define the services that the company library offers its users having in mind the changes that have taken place concerning the availability of information. I also wanted to explore whether the librarians had the necessary competence to perform the services offered. Six information specialists were interviewed to give their view on the services their libraries offered.
