Under 1970-talet såg forskare inom näringsfysiologin en stigande trend av ökad konsumtion av fett- och sockerhaltiga produkter på bekostnad av bland annat matbrödskonsumtion. I tid  av livsmedels- och energikriser förespråkade forskare en alternativ diet med ett större inslag av grönsaker och fullkornsprodukter då det hade slagits fast att ett högt intag av fett och socker ledde till bland annat hjärt-kärlsjukdomar samt karies. Matbrödsproducenterna och Socialstyrelsen höll med experterna och detta ledde till ett samarbete mellan parterna som mynnande ut i Brödkampanjen med start år 1976 där den svenska befolkningen uppmanades att äta mera bröd. Denna undersökning har visat på hur experterna argumenterade för en ökad brödkonsumtion och varför just bröd var ett bra alternativt livsmedel genom att ta del av Socialstyrelsens arkivlämningar med intervjuer av experterna bakom kostrekommendationen..

Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not. The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).

The present study examined high school students? attitudes to higher education at university/college and their study engagement in an industrial town in klarälvdalen in the county of Värmland. The main research question was whether there are any differences between students in vocational and theoretically oriented programs regarding their attitude to higher education and study engagement. The results was also compared with a study with the same research question conducted in Countryside town in fryksdalen, Värmland county to see whether attitude and student engagement differ between high school students in different parts of Värmland. The method used was quantitative with data collected by using questionnaires.

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.

AimThe purpose of this study was to investigate the relationship between off-ice horizontal jump tests and on-ice skating among students at hockey high schools. Questions: What is the association between the performance on horizontal jumps and skating 10 meters standing start among students in Swedish ice hockey high schools? What is the association between the performance on horizontal jumps and skating 10 meters flying start among students in Swedish ice hockey high schools?MethodStudents at three ice hockey high schools in the Stockholm area participated in the study. Two schools were national approved sports educations and one at lower level. All 50 students (41 at national approved sports educations and 9 lower level) that were included in the study were men and went year one and two in gymnasium.

Diabetes type 2 is a fast growing illness and a global health problem, often a result from less appropriate standard of living. Lifestyle changes related to diet and physical activity are important lifestyle changes regarding to get control of the self-management and to avoid vascular complications.AimThe aim of this study was to describe patient's experiences of lifestyle changes in diabetes type 2.MethodA literature study was carried through based on 12 qualitative scientific articles.ResultsThe analysis result into two main themes and eight subthemes. Main themes where barriers and motivators for lifestyle changes and the subthemes where struggle, denial, lack of knowledge, alienation, support, motivation, acceptance and knowledge.ConclusionThis study shows that lifestyle changes are experienced different by patient with diabetes and nurses should therefore be aware of the unique and specific demands these patients require. This is important for providing a good diabetic healthcare and to help patients with their self-management.

Teenagers are the group that spends most money on clothing. When choosing clothes, the so called internal and external signals could affect the perceived quality of the teenagers. The external signals are for example price, brand and place of purchase while the internal signals are the physical composition of the product as for example garment and size. The perceived quality is the attributes that the teenagers perceive that the specific article of clothing has. Today?s marketing, within the fashion line, is mostly to present the design of the product and aim the marketing for curtain segments and to keep a distance to others that are not within the segment group.

The focus of this essay is to further investigate and describe psychological strains experienced by child welfare workers. The method used was qualitative interviews, two group interviews. The research aimed to understand how child welfare workers were affected and handled the psychological strains generated by work through theory of coping and symbolic interactionism where humans are viewed as pragmatic actors. The research showed, as previous studies shown, that the child welfare workers experience a great deal of psychological strains generated by high turnover in staff and pressuring work demands. The child welfare workers felt inadequate and alone in their work tasks and experienced stress and anxiety.

This study examines in which way literature is presented in four schoolbooks for the Swedish senior high school of today, compared to descriptions and selections in Swedish universities. The study covers two basic schoolbook categories used in the teaching of Swedish and comparative literature: anthologies and textbooks.The four anthologies structures and their joined canon are presented, and the text canon of 12 common writers is studied and compared to the corresponding text canon in the universities selection of texts to main courses in comparative literature. The four textbooks are analysed by close reading of the presentations of four different writers and their works, where the textbooks for the Swedish senior high school are viewed through the glass of literary guides used in Swedish universities.The study also analyses what literary perspective is present in the Swedish school principles for education in literature and display, through earlier didactic studies, a sketch of the classroom reality of education in literature.The study finds that the examined schoolbooks for the Swedish senior high school tend to, not only shorten the text length and amount of texts but also, simplify the selection and presentation of the writers production. This leads to certain fixed and, in some cases, almost stereotyped ?roles? that are assigned to the writers and limits their production.

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

RA-patients experience daily pain which affect their prosperity. The aim of this literature study is to illuminate some factors that influence the well-being of patients with RA. The factors that have been studied are pain, nutrition and need of knowledge about nutrition.

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

This essay deals with the issue how to define the concept successful school and what ingredients it includes. To aim this task I have interviewed four principals at upper secondary schools, two placed in community schools and the other two working for non-community schools. We have discussed how the principals define a successful school, whether they believe that the principal has a major part in contributing to the schools success or not and further if they think that schools have anything in common with private companies.The principals all agreed on what components they believe a successful school consists of, that is good school results from the pupils, a high comfort level for the pupils at school, professional management from the principal and a high level of young people who wants to attend the particular school.Further I have studied Swedish and foreign research in the area of successful schools and management in schools to get at good background in this matter..
