Rörelse och verbalisering- en studie av språkets påverkan på kategoriseringen av rörelsesituationer
This essay attempts to show a relativistic effect on the representation of motion situations. A summarize and defence for lingusitic relativity as scientifically valid and some taxonomic clarifications is initially presented. The relativistic effect is measured by using the elicitation tool Event Triads, developed at the Max Planck Institute for Psycholinguistics. The tool consists of a set of films displaying various motions. Test-subjects are asked to verbalize a situation in a way they see fit.
Ska vi använda Stor bokstav . och ? : Kan intensivundervisning under en kort period öka elevers förståelse för användandet av stor bokstav, punkt och frågetecken?
Are we able to help younger students to develop their understanding and their use of the capital letter, dot and question mark by giving them intensive teaching on the subject during a short period, and would the effect be long lasting?I decided to investigate this together with young students in second and third grade and at the same time try to see which grade would benefit most.By using an experimental research design I conducted the investigation in a class with children from both grades where the result was compared with two similar control groups. The investigation lasted during five months, while the students were able to show their knowledge in the subject just before and after a two weeks period of intensive teaching and then again after four months.The result showed that the intensive teaching had an effect that lasted over time and that it was the students in second grade that would benefit most. .

Effekt av tillskott med isoflavonoider från sojabönor på LDL-kolesterol hos vuxna - En systematisk översikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Effects of isoflavone supplementation from soybeans on LDL-cholesterol levels in adultAuthors: Malin Blomgren Alegria and Ruut ReivaaraSupervisor: Lena HulthénExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-08Background: One of the most common causes of death in Sweden is due to cardiovascular diseases such as heart attack and stroke. Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.
Har ungdomsarbetslösheten påverkats av regeringens sänkning av arbetsgivaravgiften?
Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..
Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011
Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).
Successiv avtalsbundenhet : En beskrivning av modellen och dess närvaro i svensk rättspraxis
Why has some cyber-attacks been more successful than others? There has been in the near past examples of cyber-attacks used with different purposes. How do we understand these chosen targets and what result the attack accomplished?Research has discussed similarities between aviation warfare and cyber warfare, and how the first could explain what is happening in cyber warfare now. There is also opposing opinions whether cyber warfare should be seen as a method to alone force a will on your opponent or if cyber warfare should mere be supporting other military means.
"Jag har blivit en bättre mamma" : En studie om deltagarnas upplevelser av föräldrastöd i grupp
The aim of this qualitative study was to investigate the participants experiences of a parent support group and the effect of their participation on their parental role from a learning perspective. As the parent support group takes place as a group activity, the focus was on the individual learning processes which, in turn, are influenced by both the group itself as well as the leaders of the group. The empirical data was collected from a focus group interview with four mothers, and analyzed using empowerment and coping theories. Based on the participants´ narratives, the result showed that the parent support group had a great social and pedagogic effect on the participants. As a result of the received knowledge in the group from both leaders as well as from other participants, they felt less stressed and more confident in their parental role.
Blod, svett & tårar : En studie av vad som skapar varumärkestillknytning till träningscenter
We have examined how the dependence, identity and social bonds affect customer loyalty and attachment to a training centre. The method used is a survey on SATS Karlstad city where 128 respondents were asked, out of which 118 surveys were used in the final analysis. The data was analyzed using ANCOVA and multiple regressions.The result showed significant relationships on attachment between identity and dependence. Social bonds had no significant effect on the attachment a member have towards training centre. Customer loyalty was measured by how long the individual has been a member and his or her training frequency.
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.
Elevers syn på klimatfrågan : Klimatundervsiningen i skolan
The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming. I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.
This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.
Inlösen eller extrautdelning?: En studie av sambandet mellan valet av kapitalåterföringsmetod och värdeskapande för aktieägarna
This thesis studies the stock price reaction around 68 announcements of special dividends and share redemptions on the Swedish stock market between the years of 2003 and 2007. We show that for the Swedish private investor, the tax effect of a share redemption is lower than that of a special dividend. Moreover, a share redemption could be interpreted as a signal of undervaluation. These two factors lead us to assume that the stock market would react more positively in connection to the announcement of a share redemption. We test this hypothesis through an analysis of the risk-adjusted abnormal return for the observations in the sample.
Kodens påverkan på börskurser : En event study på publiceringen av bolagsstyrningsrapporter enligt Svensk kod för bolagsstyrning
Recent accounting scandals, often led by managers trying to improve results and thereby their own bonuses, have severely damaged the publics view of management. In the aftermath of scandals such as Enron, Parmalat and Skandia, demand has increased for Corporate Governance codes and similar regulation. The Swedish code for Corporate Governance came into effect on July 1, 2005. The code requires all Swedish companies listed on the Swedish Stock Exchange (OMX A- and O-list), with a turnover exceeding 3 billion SEK, to disclose a report regarding Corporate Governance, attached to the annual report.The purpose of this paper is to examine whether the new disclosure required by the Swedish Corporate Governance code will have a measurable effect on stock prices. The authors have applied event study methodology examining daily returns around the announcement of the Corporate Governance reports.
