Konflikter -En kvantitativ studie om effekter av konflikter och konfliktstrategier på arbetsplatsen.

A quantitative study was conducted with the aim to investigate whether individuals use a specific conflict strategy when they are in a task conflict or a relationship conflict in their workplace. The study also examined whether individuals experience positive or negative effects of a task conflict or a relationship conflict when a specific conflict strategy have been used. Previous research explains the effects of task conflicts and relationship conflicts at the workplace (De Dreu, 2008) Likewise lifts the effects of the conflict strategies interaction, avoidance, and power and coercion (Hoerr, 2005; Meyer, 2004; Trudel & Reio Jr., 2011). However it does not tie together what the conflicts and conflict strategies have for effects together. This also means that it is impossible to discern if there is a strategy that is frequently used in a specific conflict type. The study group consisted of 62 participants from different workplaces that responded to a survey.

Validering av metoder för analys av Cu, Fe och Na i processvatten med AAS-grafitugn

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Wildlife Detection Network

Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.

Kulturskapare eller serviceorgan? : en studie över folkbibliotekets uppdrag i samhället idag

The subject of this thesis is to ascertain the task of the public library in Swedish society today according to the employer, that is the State and the municipalities, and according to the public library itself. The thesis also tries to establish as to what extent these different actors share the same view of the task. To this purpose I have studied the library law, the target reports of municipal authorities and public libraries, and made interviews with public library representatives during the autumn of 2001. The particular consideration of this paper is whether the task is being described in active, culture making terms or in passive, service functionary terms. Initially, I describe the task according to the library law.

Police Science - expansionen av ett kunskapsfält : En studie om vetenskapligt gränsdragningsarbete i 1930-talets Chicago

In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.

Åtskildheten : En lacansk läsning av Birgitta Trotzigs roman Sjukdomen

While almost 23 percent of the students in the Swedish upper secondary school are foreigners, only a fraction of the school libraries? collections consists of literature written in other languages than Swedish or English. This study examines how five school librarians experience the task of working with literature composed in foreign languages in the multicultural and multilingual school of today. The results of the qualitative interviews are analyzed in relation to the legislation and policy documents that the school libraries are working by, and also in relation to the theoretical framework of sociocultural theory and the theories on second language acquisition developed by linguist Jim Cummins.The study shows that while multilingualism is discussed as an important matter in the legislation and policy documents that the school libraries work by, the librarians in this study largely view the question of foreign literature as peripheral. Most part of the librarians connects first language reading to leisure-time activities rather than curricular activities, and stresses that the Swedish language should be prioritized in Swedish schools.

detection and quantification of almond (Prunus dulcis) in food with ELISA

Reliable methods to analyze food for the presence of almond are important ? not only for those allergic to almond, but also for monitoring the compliance with labelling regulations (EG directive 2003/89). Until now the Swedish National Food Administration has used methods like rocket immunoelectrophoresis and real-time PCR to detect almond in food. These methods are, however, not sensitive enough for protecting the most sensitive individuals. Therefore, the performance of a commercial ELISA kit was tested with regard to specificity/cross reactivity and limit of detection for almond both in solution and in different matrixes.The limit of quantitation was at least 3,1 ppm (mg/kg) in solution and similar concentrations were measured in bisquits and chocolate.

Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor

During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.

Improvement of positive strand assay used in detecting positive and negative RNA of hepatitis E virus

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).

Utveckling av I/O-modul för trafikskyltsystem

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

Another purpose was to study differences in motivation, perceived ability and motivational climate among men and women. The final purpose was to study interactional effects on the dependent variable motivation. The participants were 59 men and 69 women. The instruments used were Task and Ego Goal Orientation in Sport Questionnaire (TEOSQ), Harter´s Competence scale and part of Mahoneys R-5 test.

Instruktionsfilm på smartphones : En studie kring upplevelsen av video via smartphones som inlärningsverktyg för praktiska färdigheter

This study examined how users interact with a smartphone while in a learning situation based on videos via smartphones as a learning tool, and how this interaction and phenomena is experienced. The five test subject were separately given the same task that they were to solve using video instructions that were picked out and given to them. After finishing the task the subjects were observed while they demonstrated how they completed the task. After the observation the subject were interviewed using semi-structured interviews. The results show that the user experience of this phenomena is based on more pragmatic values than we could find in earlier studies, i.e.

Det mångspråkiga skolbiblioteket : En viktig fråga i teorin men en icke-fråga i praktiken?

Inlärning och öppet-fält aktivitet hos förskolebarn

The purpose of this study was to analyze the impact of learning on open-field activity among pre-school children varying from 3 to 5 years old. Altogether 25 children, 13 girls and 12 boys, entered the test from three different preschools in Dalarna. Six of these children represented the control group. The children were asked to learn 2 tasks, 1 visual memory task and 1 spatial constructing-kit task. Before, between and after the tasks, the children were allowed to move freely in the open field.

Comparison of two methods for evolving recurrent artificial neural networks for

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.
