Ungdomars attityd till hälsosam kostvana : En kvalitativ studie om ungdomars inställning till att förändra sina kostvanor för att uppnå hälsa
Det allmänna hälsotillståndet är ett resultat av de levnadsvanor som individen har och lever under. En förändring av vanor är starkt relaterat till individens attityd och inställning!Syftet med den här studien, är att undersöka ungdomars attityd till hälsosam kost och inställning till att förändra kostvana, samt söka klarhet i vilka eventuella hinder och incitament som föreligger vid en förändring av kostvana..
Utveckling och implementering av ett audiopejlsystem baserat på tidsdifferensmätning
The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.
Anställningsotrygghetens effekt på självskattad hälsa, i hög respektive lågkonjunktur
The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..

Peas as feed for dairy cows
AbstractAn approaching overproduction of cereals and a future uncertain supply of non genetic modified vegetable protein feedstuffs have increased the interest in an expansion of the domestic production of protein feedstuffs in Norway. Besides rapeseed (Brassica campestris), peas (Pisum sativum) may be the most suitable crop for this purpose. Peas are characterized by having a relatively high content of crude protein, ranging between 20-26%, a high content of starch, 42-51%, and a low content of fat. In general, the energy value for peas is higher than for barley but lower than for rapeseed and soybean meal.Pea protein consists of albumins and globulins to 85-100%, which leads to the fact that a large part of the pea protein is soluble and degradable in the rumen. Starch in peas is on the other hand to a large extent resistant to rumen degradation compared to starch from other starch rich feedstuffs.
Kontorsanställdas psykiska välmående i relation till deras fysiska aktivitetsnivå
Background: There have been doping usage as far back as as ancient Greece and around the early 1900s started the doping we have today. In 2008 it was 22,000 men aged 15-54 years old who had any kind of experience with doping in Sweden. The problem of doping use are all over the world and to overcome this problem, we need to work across borders.Objectives: The purpose of this study is to investigate whether there is any connection between the use of supplements and attitude to doping. The study is based on the questions: is there any connection between the use of supplements and positive attitude to doping? is there any connection between the use of supplements/doping substances and high training frequency? and is there different use of supplement/doping substances between girls and boys?Method: A survey in form of a cross-sectional study and a waiting room survey was conducted with 63 respondents of whom 57,1% were women.
Betydelsen av tidig hantering av nyanlända försökshundar till en försöksdjursavdelning :
AstraZeneca in Mölndal (AZRDM) uses beagles bred at Rååhöjdens kennel in Örkelljunga for their research purposes. The staff wishes to have mentally stable dogs to work with, sine stress can effect the research results.
The purpose of this study was to put together the testresults from dogs delivered 2003 and 2004, to see if there is a connection between delivery age and testresult. We have also worked out a method to test if early planned handling of the dogs makes a difference on how the dogs later respond in a testsituation, and tried this method in a pilotstudy.
The data that we have based our calculations on is 172 dogs, divided into 108 males and 64 females.
We found a significant connection between the age at delivery and the testresult in contactability for female dogs delivered in 2003, where increasing age led to decreasing grades in the test at AZRDM. When looking at the difference in testresults between test number two at the kennel and the test at AZRDM we found a significant connection for female dogs delivered during 2003, ie the difference takes on a more negative value with increasing age at delivery.
We found a difference between the two sexes in our calculations.
Icke-triviala billigaste väg-ruttningskonflikter - klassificering och sökmetoder
Within telecommunication and routing of tra?c in IP-networks a protocol named?Open Shortest Path First? (OSPF) is widely used. This means that a server dealswith the routing over a network with given weights by calculating shortest paths touse for routing. If we assume that a desired tra?c pattern is given the problem isto ?nd out if it is possible to set the weights so that the desired tra?c pattern is apart of a shortest path graph.
Får elever bättre uppmärksamhetsförmåga efter fysisk aktivitet? : En experimentell studie om fysisk aktivitets påverkan på uppmärksamhet
The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.
Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam
In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status.
The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.
"Fallbacks" - betydelsen av vandringstid för Atlantlax (Salmo salar L.) som faller nedströms vandringshinder
In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.
Kvinnligt eller manligt - En studie av könsbedömningsmetodernas utveckling för humant material
This study focuses on the development of methods for sexual determination of human skeletal remains, mainly between the years 1981 to 2007. By comparing an older analysis from 1983 (Persson and Persson) with my own on the same material, a difference of 40% was shown, which indicates that the methods has changed through time, and that these should not be used for newer conclusions about a population if the method is not throughoutly described.The main cause of the difference was identified as a change in the reliability of the sexual indicators, rather than a total change of method. Any general tendencies did not show, it is however considered that the pelvic bones are able to make a better conformity between the analyses as opposed to using the cranium..
Vad har en AD/HD-diagnos för betydelse för barnet i skolan? : Sett ur pedagogens, specialpedagogens, läkarens och förälderns perspektiv
The purpose of this research has been to study and find out if a diagnose AD/HD is of importance. Does a diagnostic significance matter for how to support and respond to children in school? Are diagnosed children with signs of AD/HD treated differently than children without diagnosis? My study is based on input from teachers, special educators, from two different schools and also one doctor and one parent.I have interviewed teachers, special educators, one physician and one parent. I have been using qualitative interviews with tape recorders and emailed them with open questions. I have been using literature; see bibliography.
Brottsrapporterande och engagerande : En kvalitativ studie kring polisens arbete och kommunikation inom det sociala mediet Facebook
The purpose of this study was to understand whether there is a difference in how the Swedish police work with Facebook in two municipalities with different criminal records. The methods used were qualitative interviews with the ones responsible for the Facebook-sites and quantitative content analysis of different Facebook-posts, both from members of the Facebook-site and from the police themselves.Among the theories used in this study were the ?four-step relations process? by Cutlip, Allen and Broom, theory around public relations and theory around the public sphere by Habermas.The results showed that there is a difference in how the police uses Facebook between the municipalities and one of the conclusions is that this is mainly because of the ways that the police choose to work with Facebook rather than the difference in criminal records. Another conclusion is that the police get positive feedback from the members on their Facebook-site, and that how much the police uses Facebook as a tool depends a lot on how much resources they have to spend since the ones writing on Facebook are policemen and policewomen, and that the police do not have someone who works with the Facebook-site as a primary task.Keywords: Facebook, police, social media, qualitative interviews, quantitative content analysis, authority, public relations..
