Jordbruk kontra industri : jordbruksregleringar ur marknadsstrukturmässigt perspektiv
What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.
Genetisk variation av betydelse för adenosinsignalering vid nydebuterad reumatoid artrit
Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.
Kinetikens tecken: en experimentell studie i samspelet mellan kroppens rörelser och dess försvarsmekanismer
Relationships between defence mechanisms and body movements were investigated in regard to three hypothesis; I. that a difference in frequency of body movements correlates to different signs of defence mechanisms, II. that themes of body movements can be identified in regard to signs of defence mechanisms, III. that no significant differences will be found between the different groups of gender. The aim of the study was to seek a relation between quasicommunicative body movements and defence mechanisms.
För vem redovisar i första hand hjälporganisationer?
The purpose of this essay was to identify the primary stakeholder in aid organisations, by which we mean whom they make their annual report for, and to analyse if there were any differences considering the design of their annual reports depending on which their primary stakeholder is. The method we used to explain the choice of primary stakeholder and the differences in the annual reports was a multiple case study. The collected data came from telephone interviews with 23 representatives from aid organisations and a review of annual reports. The results were analysed through pattern matching. We found that aid organisations do not have a primary stakeholder as in incorporated organisations.
Injuries associated with climbing: a questionnaire study
Background: During the last decade climbing has become more popular and the numbers of climbers in Sweden have increased considerably. Most common are overuse injuries caused by the great stress and strain climbing creates on different parts of the body. Previous studies show that 75-90% of climbing injuries are localised in the upper extremity. Injuries affecting the lower extremity occur often acute and traumatic. Based on these facts and that the number of climbers constantly grows, it is more likely that the need of care from physiotherapist among climbers will increase.
Uppnår sjuksköterskestudenter lärandemålen?
Objective: To see if nursing students believe that they have acquired the knowledge that the Higher Education Ordinance demand and if there is any difference between the theory learned at the University and the clinical reality in which students receive their practical training. Method: The method is quantitative and is divided into two parts, one in which the authors describe how the questionnaire was developed and how validity was strengthened. In the second part, the authors describe how the data analysis was made and how reliability of the result was strengthened. Result: The result shows that the students felt that they have achieved most of the objectives of learning demanded by the Higher Education Ordinance. But some objectives are perceived as not at all or only partly achieved.
Syntaktisk komplexitet hos ungdomar och vuxna med läs- och skrivsvårigheter
The purpose of this thesis is to investigate if there are any differences regarding syntactic complexity in written language between persons with (phonologically based) reading and writing difficulties and a control group. Earlier research has pointed to such a difference, indicating that texts written by subjects with reading and writing difficulties display a lower grade of syntactic complexity than text written by control groups.Two texts each from 48 subjects (24 from each category) were collected. The subjects were divided in two age groups, one consisting of 15-year-olds and the other of university students (adults in various ages). The subjects were selected through a word decoding test and a spelling test, where the lowest performing formed the group of reading and writing difficulties and the highest performing formed the control groups. All subjects had Swedish as their mother tongue.The syntactic aspects studied were number of words per syntactic sentence (Sw.
Olja, mer än bara svart guld? : En studie om korrelationen mellan och möjligheten att skapa en handelsstrategi med olja och växlingskursen SEK/USD
Syftet är att konstruera en handelsstrategi baserad på Contracts-For-Difference (CFD) för att utnyttja de möjliga samband som föreligger mellan oljepris och SEK/USD växlingskurs.Uppsatsen baseras på en induktiv ansats med kvantitativ metod. Slutsatser dras från utifrån de data som har bearbetats.Korrelationen mellan olja och valutan SEK/USD är starkt negativ. Funktionaliteten hos ?Moving Average? som indikator för trendskiften bedöms som relativt hög. Handelsstrategin som har konstruerats uppvisar positivt resultat efter fem års simulerad handel.
Design comparison between HiperLAN/2 and IEEE802.11a services
This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

Att tänka jämställdhet är en sak, att göra jämställdhet är en annan : En kvalitativ studie om hur biståndshandläggare beaktar jämställdhet i utredningar
The aim with this study is to analyze how Swedish social services interpret men's and women's needs and whether it is possible to discern any pattern in the social services investigations. The following questions are of importance: how men and women are described in the assistance investigations and if there are any differences between men and women in assistance investigations. The analysis is based on a qualitative text analysis of twenty assistance investigations. The investigations have been studied gradually and interesting patterns emerged which were analyzed by the theory of gender.The results are multifaceted and demonstrate on the one hand that men and women receive the help they apply for and the assessment of their needs is conducted in an equitable way. On the other hand, the study demonstrates that there is a difference in how men and women are described in the investigations..
Kan man identifiera de karaktäristiska dragen hos stop-motion och applicera dem inom 3D-animation?
For any animator either working in stop-motion or 3D-animation the knowledge of the first animation techniques are most important. For it is based on these principles that animation today can create such vibrant characters. With the extreme development 3D-animation has undergone the last twenty years it is easy to lose track of the old ways. But with this thesis a hope to show that it is these old ways that will take animation to its next stage. My aim with this thesis is to find out if it is possible to identify the characteristic features of stop-motion and apply these onto 3D-animation with purpose to create a more expressive style of animation.
