Informationskvalitet: informationssökares syn på kvalitet
The aim of this thesis is to examine how different kinds of information seekers are evaluating information quality in the information flow online. To address the problem stated, qualitative interviews were carried out with a librarian as a reference person and a group consisting of journalists and scientists. The result of the study implies that the reference person is well aware of the strategies employed by her in the search process. However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.
Kontrollerat och okontrollerat språk En litteraturstudie i informationsåtervinning i databaser.
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.
Marknadsmässig spannmålshandel
The agriculture throughout the world is becoming increasingly deregulated and this has affected the prices of raw materials to fluctuate at a higher degree than earlier. This in turn has made it interesting and in some cases even necessary for the trader as well as the
producer to gain knowledge about the trade instruments available to ensure a good enough price for their produced goods. This study encompasses a number of ways to
trade grain and oil plants in order to clarify what differences there are in the several contracts that exist in the present situation, economical as well as practical. The various trade instruments available to the producers on the Swedish market are described in the theoretical part of this study.
The study also contains a simple arithmetic example, based on historical prices collected from grain traders and trading floors, in order to point out the differences in the
economical outcomes depending on the business strategy used to sell the produced goods.
The study shows the importance, as a producer, of being able to use and take advantage of the different trading instruments at hand to monitor and exploit the shifts in the
market. From an economical point of view it is not enough to just excel at farming but knowledge about the market functions and the trade instruments at hand is also required
to be able to secure a good enough price for your goods.

Jordbruk och mjölkproduktion med kor i Etiopien :
Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.
En psykometrisk utvärdering av det arbetspsykologiska testet Predicting Job Performance
Ett psykologiskt test används främst inom utbildningssammanhang och kliniska sammanhang, men även inom rekrytering, urval och organisationsutveckling. Det finns idag ett flertal personlighets- och begåvningstest som mäter olika aspekter som kan vara relevanta för en organisation. Predicting Job Performance, PJP, som har sin utgångspunkt i femfaktormodellen, är utvecklat av Psykologiförlaget AB och består av två delar som mäter olika dimensioner av personlighet och begåvning. I denna studie har psykometriska beräkningar utförts för att utvärdera instrumentets reliabilitet samt validitet, främst genom test-retest-metoden. Undersökningsdeltagare var 49 psykologistudenter vid Stockholms Universitet.

This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.
Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
Reducering av beröringskänslighet på hörselprodukter
Vi har i samarbete med HemoCue AB utfört ett exemensarbete inom konstruktionsteknik. HemoCue AB utvecklar, tillverkar och marknadsför patientnära medicinteknisk utrustning. De erbjuder testning av patienter på ?plats? med samma noggrannhet och precision som om testet skulle ske på ett laboratorium med ett laboratorium instrument. Syftet med detta projekt var att ta fram en laddstation till ett mätinstrument.De krav som vi hade att följa var många, de mest utslagsgivande var dock att laddstationen skall vara placerad liggandes på bordet och att användning av instrumentet under laddnings tiden skall vara möjlig utan några som helst problem.De metoder som vi valt att arbeta efter är dels Brainstorming och dels Fredy Olssons metoder för Princip- och primär konstruktion(1976). Vi har även tittat en del på Arne Åkessons tillverkningskonstruktion(1981). Att vi valt att arbeta med dessa är för att få med all viktig dokumentation, från idé till färdigt konstruktions underlag.Detta examensarbete har resulterat i en prototyp av en laddstation som uppfyller samtliga krav och önskemål som vi haft att arbeta efter. Det underlag som vi tagit fram kommer HemoCue AB troligtvis att utveckla ännu lite längre innan laddstationen kommer att i bruk..
Framtagande av ny höjdmätningsmetod till försvarets antennhiss 861
This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.
Importens påverkan på Etiopiens jordbruk : en välfärdsteoretisk analys av Etiopiens import från Europeiska Unionen
Trade is important for every country in the world. Commodities are transported between rich and poor countries everyday. Some of the trading partners are EU and Ethiopia, this because of less expensive commodities from EU than they are in Ethiopia. The most important agricultural commodity is wheat. Ethiopia is a poor country, whose inhabitants mostly are living on agriculture.
Bevarande av de svenska lantraserna, populationsgenetiska och molekylärgenetiska metoder
Today?s community requires an increase in food production. Animals are today bred so that they produce more than their ancestors did. Production has been the most important and breeds with the highest production levels have therefore become popular. Many of the old local breeds have become extinct or are about to become extinct because of this trend.
Vad gör egentligen en landskapsarkitekt? : en studie av hur yrkesrollen framställs och upplevs
This is a thesis written at the Swedish University of Agriculture inAlnarp within the landscape architecture education. The essay dealswith the landscape architect's professional identity and how it isdescribed in different contexts along with how it is perceived byprofessional landscape architects.Misunderstandings and preconceptions concerning the landscapearchitect's professional identity is common, both within and outsidethe branch of industry that includes the vocation. This raises problemswithin the industry and for the individual landscape architect. To findout if the root of the problems lies in available descriptions of theoccupation a study has been made. The study includes how thelandscape architect is defined in easily accessible information fromthe internet and in literature as well as in industry-orientedinformation such as dissertations and information from SverigesArkitekter (the Swedish Architects).
Vad påverkar beslutet av missbruksvård? : Faktorer som kan påverka val av insats
Title:What influences the assessment of addiction treatment? - Factors that may affect thechoice of interventionsThere are few studies on trauma and the importance of religion for the professional handlingof abuse clients in a Swedish context. It is therefore appropriate to examine the role of suchfactors. This study examines whether experienced trauma in childhood or religious beliefsinfluence the assessment and selection of input in fictitious cases. To examine this created sixvignettes.
Uppföljning av plantering på nedlagd åkermark i Skåne 1991-1996 :
The study was performed for the Swedish Regional Forestry Board in Södra Götaland. The study examines broadleaf plantations on former farmland that were planted between 1991 and 1996 with subsidy payments for conversion of farmland into forest. In particular, the study reviews forests planted in 1991-92 and 1994-96.
In the early 1990s, Swedish agriculture was deregulated and direct subsides to farmers ended. The Swedish state instead granted farmers financial support and offered incentives for conversion of farmland and investments in order to make their unproductive land productive.
The state supported conversion of farmland to broadleaf forest, forest for energy biomass production, or establishment of wetlands on former farmland. The County Administrative Boards and Regional Forestry Boards together monitored the planting of broadleaf forests.
