Google Scholar eller Scirus för vetenskapligt material på webben? En utvärdering och jämförelse av återvinningseffektivitet.

This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.

Tre metoder för diagnos av mastit i fält :

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

We've both said things you're going to regret : En undersökning av dagspressens framställning av TV-och datorspel perioden 1995 till 2012

The use of computer and video games has increased immensely over the past few decades and today a majority of the Swedish population enjoys them on a daily basis. With such a large number of frequent users, the media reporting on the subject of games becomes interesting and important. How are games represented in the media, and has there been any change in the way they are portrayed as their popularity has grown? ­The aim of this study is to determine if and how the portrayal of computer and video games in Swedish newspapers has changed during the period 1995?2012. The study was conducted with the use of quantitative content analysis and the empirical data was collected from the two most widespread newspapers in Sweden ? DN and Aftonbladet.

Pojkar som inte lyckas i grundskolan

The purpose of this essay was to examine pupils who leave the Swedish nine-year compulsory school system without reaching the requirements for the Swedish senior high school, and then to compare with those who reach the requirements. I used the following questions to help me reach this purpose:- Where in life are those pupils who reached the requirements for the Swedish senior high school?- Where in life are those pupils who did not reach the requirements for the Swedish senior high school?- What differences are noticeable between these two groups?The method that I used to examine these questions was to send out a questionnaire to the pupils. I also tried to make an explanation to the results with the help of Erwin Goffmanns theories.The result of this essay shows that there is not a big difference between the two groups. They both did equally well after they finished the Swedish nine-year compulsory school..

The Trivial Pursuit: Den modererande effekten av kunskap och engagemang på utvärderingen av produkter med triviala attribut.

Research has concluded that meaningless differentiation with trivial attributes sometimes can be a successful strategy. However, the effect varies with respect to certain aspects such as the price of the product and the decision context. How the characteristics of the consumer influence the effect of trivial attributes has until now been unknown. This thesis investigates how the consumer?s level of knowledge and personal involvement influence the effects of trivial attributes on product preferences and product attitudes.

Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

Högriskfonder kontra aktieindex : En studie av makrovariablers påverkan på olika fondalternativ

Att arbeta med ständig osäkerhet : En studie av High Reliability Organization

There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.

AHA in northern Sweden ? a case study : conservation values of deciduous trees based on saproxylic insects

AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.
