Attityder inom extrem kampsport : En undersökning om Mixed Martial Arts inverkan på utövaren

There have been debates on the big differences in mathematics knowledge concerning pupils in Sweden and Finland. Especially, one common issue in the discussions of education is the Pisa test results, which take up in the media. In the Pisa research the Finnish pupils get through well year after year. Because of the discussions about the distinct school systems in Sweden and Finland, I found it interesting to investigate the divergence of the curriculums in these two countries. The main research questions asked were, what are the main differences and similarities in the Swedish and Finnish curriculums in primary school? Such as, is the assignment of primary school similar in Sweden and Finland?In my study I analyzed and compared by means of the curriculum especially mathe-matics teaching in primary schools in grade three in Sweden and in grade two Fin-land.

Traktkilars inverkan på hovens glukos- och laktatmetabolism :

The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can?t store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production. Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired.

Utsmyckningsidentitet En studie om äldre bronsålderns utsmyckningskombinationer funna med halskragar och halsringar.

The aim with this essay is to explore the possibility that jewellery was worn in combinations during the Bronze Age in the south of Sweden and Denmark as a way to show identities. By examining neck-collars and neck-rings and the jewellery found with these objects in graves, I have managed to find a few combinations that re-occur within regions which I think point towards ways of expressing different identities.To fully explore the subject I have also examined the design of the neck-collar to see if the designs have the same regional difference as the combinations. Though there is some difference between regions it is the similarity of the design over regions that stand out. It is possible that the design of the neck-collar has shown a different meaning than the jewellery combinations.There are similarities between the jewellery found in combinations in the graves and the jewellery found in hoards. Neck-collars and neck-rings found in combination with other jewellery in hoards show a greater regularity over the south of Sweden and Denmark then those combinations found in the graves..

Matvanor bland 15-åriga pojkar och flickor i Uppsala län

Aim: To describe perceptions about written and verbal information regarding diet and physical activity in women with breast cancer and to study possible differences between ages and perception. Method: A cross-sectional study was conducted and consisted of 57 women with breast cancer stages I-III who started adjuvant chemotherapy within a year (2007-2008). A questionnaire, regarding their perceptions about the written and verbal information they had received about diet and physical activity, was responded to three months following treatment completion. Between 67-93 % of the participants responded to the questions. The answers was analyzed with descriptive statistics and Mann Whitney U-test.

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

Lust och disciplin: Medelålders kvinnors konsumtion i det senmoderna samhället

The purpose was to look into the pattern of consumption among middleage women. Our questions were how women experienced the need to consume, how they defined the expression of consumption and if there was a difference between "shopping" and "buying". The research has been done through eight qualitative interviews and searching in litterature, illuminating our questions.All women defined consumption as satisfying basic needs. According to them everything bought on a daily bases is consumption. More difficult to define was the experience of "need".

Organisationskultur ur säkerhetsperspektiv ? en fallstudie utifrån Cultural Theory

The aim of this master?s thesis is to identify differences and similarities, regarding security, in two goods terminals in an organisation in the transport and goods sector. In this thesis we use Cultural Theory as an analytical instrument to investigate organizational culture, as seen from a security perspective. Cultural Theory is a theory seen from two perspectives, the stable perspective and the mobile perspective. These two perspectives concentrate on different research areas.

Tillväxtreaktion på kvarlämnade träd i Hagners "Naturkultur" försök :

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag

The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.

Lättläst eller inte? : En läromedelsanalys av lättlästa läroböcker, inom ämnet svenska, anpassade för elever med läs- och skrivsvårigheter

The demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.

BREAM : Domänanpassning av olycksanalysmetod till sjöfarten

Syftet med följande studie var att undersöka hur olycksanalysmetoderna CREAM och DREAM kan anpassas till sjöfartsdomänen, samt hur begreppet den mänskliga faktorn kan beskrivas och hur kan den analyseras. Teoristudier samt intervjuer med anställda vid sjöfartsinspektionen och domänexperter har genomförts. Ett förslag på hur en anpassad analysmetod skulle kunna se ut redovisas som BREAM (Bridge Reliability and Error Analysis Method). Den anpassade metoden har utvärderats med hjälp av experter inom domänen. Utvärderingen visar på att metoden fungerar bra men att ytterligare specificering av metoden till domänen är önskvärt..

ART. Aggression Replacement Training. : En kvantitativ undersökning där resultat i skola och hem mäts på barns uppförandeproblem efter en intervention med ART-metoden i helklass.

SammanfattningART-metoden har i denna undersökning använts som en multimodal metod. ART-metoden utvecklades från början för barn som uppvisade ett aggressivt beteende. Där dess grundare Goldstein, Glick och Gibbs (2001) menade att ett aggressivt beteende var ett komplext socialt inlärt beteende och således inget barn föddes med. Detta resonemang resulterade i att beteendet enligt dem kunde läras om. Den mesta av forskningen som gjorts om ART-metoden innefattade barn som redan utvecklat svåra uppförandeproblem.

Kreativiteten i Humor : Domängenerella Mätningar av ett Domänspecifikt Område

The aim was to examine whether measurements of creativity as a domain general trait can explain possible connections between a domain general creative performance and one of the creative domain specific areas, humor. Another aim was to examine whether the maladaptive humor styles can explain possible differences in creative performances. An Internet-based survey was used on 281 students from a Swedish university. The survey was composed of three parts consisting of three separate measuring instruments ? Sense of Humor Questionnaire (SHQ-6) was used to measure the respondents? sense of humor, Humor Style Questionnaire (HSQ) measured the respondents? humor style and Alternate Uses Test (AUT) gave the respondents an opportunity to account for their creative performances.
