Kommunikationseffektivitet och kommunikationsstrategier för L1- och L2-talare i referentiella problemlösningsuppgifter
This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.
En undersökning om fallolyckor med gångtrafikanter
The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.
Wheat : an analysis of variables determining the Swedish price of wheat
Increasing volatility and less political intervention from the CAP in the market price of wheat is making it more difficult than in the past for Swedish farmers to determine the price at which they should sell their wheat. In the past, the Swedish farmer-owned company Lantmännen has traditionally set a guideline price for Swedish wheat every year to which farmers could adapt, but ceased doing so last year. Therefore this study sought to identify the parameters on which the price of wheat is dependent on by using a reduced form model. The perspective adopted was that of farmers. The model proved able to identify the main factors determining the annual price fluctuations in wheat, with all variables included having an impact on the wheat price, except export quantity in the previous year.
Motivera Mera! - En kvantitativ studie om samspelet emellan hedonisk shoppingmotivation och multikanalshopping
Multichannel-shopping has become a wide spread phenomenon in the retail industry due to a significant development of retail channels and formats. Consumers now shop for the same product category in many different retail settings and this trend is increasing. Therefore both the academic world and the retail industry are screaming for knowledge about the multichannel-shoppers. Several studies have focused on the characteristics of different channels and how multichannel strategies should be designed to minimize cannibalization. There is however a lack of research concerning what characterizes multichannel-shoppers and what drives them to shop in several channels.
Beteende hos lekvandrande lax i Klarälven ? utvärdering av en fiskfälla
During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).
Towards a function for an Arabidopsis protein involved in sucrose dynamics
System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.
Validering av glidande statorfötter på Hissmofors G6 och G7
Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.
Sederingsrutinens påverkan på resultatet av höftledsröntgen : en pilotstudie
Hip dysplasia is a common, inherited malformation of the coxofemoral joint that
eventually leads to osteoarthrosis. Several breeds of dogs are affected and the
prevalence varies between different breeds. As part of the effort to reduce the
prevalence of hip dysplasia and select dogs suitable for breeding, radiological
screening is performed by at least 12 months of age. Before the radiological
examination the dog has to be chemically restrained, sedated or anesthetized. The
sedation protocol used differs between veterinary clinics.
The impact of sedation method of the screening result for hip dysplasia has been
studied.
OneCore
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
När medborgaren blir en kund - vad händer då med det gemensamma bästa?
In the late 20th century there has been some changes in the public sector. These changes are described as New Public Management. When ideas from the private market is transferred to the public sector, for example to regard citizens as cus-tomer. Central in this paper is the use of term customer in the Swedish public sec-tor. There are two questions in the paper; which possibilities has a disappointed customer to effect the public sector, and what may happen with democracy, the common good, when the citizen becomes a customer?To answer the questions I study two different cases, Svedala kommun and the tax department, Skatteverket.
Lönsamheten i vindkraft : en studie om den förväntade lönsamheten i landsbaserad vindkraft
This thesis analyzes the expected profitability in land based wind power plants. The expected profitability is calculated on the basis of a wind power project in Vartofta, Falköping. The information required to calculate the expected outcome is then concentrated to this project, which is in this thesis called project Näs. In project Näs they plan to build three wind power plants, with each an effect of 2 MWh. These wind power plants are very capital intensive investments with a long and uncertain payback time.
En Fängslande Studie : Fängelsereformsattityder i Sverige
Studiens syfte var att undersöka fängelsereformsattityder i Sverige med syfte att utreda om dessa korrelerade med kön, politisk tillhörighet, ålder och urvalsgrupp. Detta utförs genom att replikera en tidigare amerikansk studie inom samma ämne. Resultaten från den svenska studien jämfördes även med den amerikanska. Urvalsgrupperna utgjordes av allmänheten(N=105), före-detta kriminella (N=48) och högskolestudenter vid Högskolan i Skövde (N=252). Respondenterna nåddes via en mailenkät.Resultaten visade att de svenska respondenterna hade mer positiva attityder gentemot fängelsereformer än deras amerikanska motparter.Före-detta kriminella var mer positivt inställda till fängelsereformer än studenter och allmänheten.
Effekter av fysisk aktivitet på psykisk ohälsa hos unga kvinnor
Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.
