Konferensbidrag (refereegranskat)abstract
- Scheduling theory generally assumes that real-time systems are mostly composed of activities with hard real-time requirements. Many systems are built today by composing different applications or components in the same system, leading to a mixture of many different kinds of requirements with small parts of the system having hard real-time requirements and other larger parts with requirements for more flexible scheduling and for quality of service. Hard real-time scheduling techniques are extremely pessimistic for the latter part of the application, and consequently it is necessary to use techniques that let the system resources be fully utilized to achieve the highest possible quality. This paper presents a framework for a scheduling architecture that provides the ability to compose several applications or components into the system, and to flexibly schedule the available resources while guaranteeing hard real-time requirements. The framework (called FSF) is independent of the underlying implementation, and can run on different underlying scheduling strategies. It is based on establishing service contracts that represent the complex and flexible requirements of the applications, and which are managed by the underlying system to provide the required level of service.

- Health is today viewed as a multi-dimensional concept partly conceptualized independent from not being ill. The aim of this study was to gain knowledge of how young children perceive health. Interviews were conducted with 68 children (4–5 years), within their pre-school setting, with the help of a semi-structured interview guide. A multi-dimensional perspective represented by the health dimensions of the International Classification of Functioning, Disability and Health (ICF) was used in a manifest deductive content analysis. The children's statements were categorized and placed under one of the four health dimensions, body, activity, participation and environment. A latent content analysis was applied to identify underlying themes in the manifest categories. The results revealed that young children perceive health as a multi-dimensional construct, largely related to being engaged, i.e. to be able to perform wanted activities and participate in a supportive every-day context. This implies that improvements of child engagement should be emphasized in health promotion and to a greater extent be the central focus of health interventions for young children.

- With the increasing incidence of prostate cancer, identifying common genetic variants that confer risk of the disease is important. Here we report such a variant on chromosome 8q24, a region initially identified through a study of Icelandic families. Allele -8 of the microsatellite DG8S737 was associated with prostate cancer in three case-control series of European ancestry from Iceland, Sweden and the US. The estimated odds ratio (OR) of the allele is 1.62 (P = 2.7 x 10(-11)). About 19% of affected men and 13% of the general population carry at least one copy, yielding a population attributable risk (PAR) of approximately 8%. The association was also replicated in an African American case-control group with a similar OR, in which 41% of affected individuals and 30% of the population are carriers. This leads to a greater estimated PAR (16%) that may contribute to higher incidence of prostate cancer in African American men than in men of European ancestry.

- In this paper we derive a method for the estimation of symmetric input–output tables (SIOTs), which makes it possible to use the commodity technology assumption even when use- and make tables are rectangular. The method also solves the problem of negative coefficients. In the empirical part we derive annual SIOTs in order to evaluate the differences between SIOTs calculated with different methods and the change in technical coefficients over time. Our results, based on data for Sweden, show that the impact of using different technology assumptions is rather large. However, in a factor content of trade application the impact of different technology assumptions does not seem to be very important. Also the size of the changes in the technical coefficients over time is found to be quite large, indicating the importance of calculating SIOTs annually.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the thesis was to describe the specific barriers young people with disabilities experience in their ambition to get a job. The aim was also to investigate how these young people’s social and economic situation has been affected by their disability. The results are based on two reports: one qualitative, consisting of interviews with 12 individuals with physical disabilities, and one quantitative in the form of a questionnaire answered by 706 persons. In the case of the questionnaire, the response rate was 48 per cent. Both reports are based on the same criteria, namely, that the respondents should have a physical disability, be 20–35 years of age and be participating in some form of employment policy program. The results from both studies show that individuals with physical disabilities encounter different types of barriers on the labour market, which can be categorised as being either at the individual level or at the social level. The barriers at the individual level are low education, long-term unemployment, grave physical disability and lack of work experience. The barriers identified at the social level are primarily poorly adapted workplaces, a too high working pace, employers’ negative attitudes, insufficient knowledge of the competence of disabled persons and an overly generous social welfare system. All these factors constitute a direct obstacle to employing persons with a physical disability. The results from the interview study show that the respondents have few social relations. The majority of the respondents have social intercourse solely with family members or parents. Most of the respondents in the questionnaire study state that they have frequent social relations with friends and acquaintances. Both the interview study and the questionnaire study reveal that the respondents’ financial position has worsened as a result if their physical disability. Conclusions that can be drawn from this thesis are that young people with physical disabilities encounter different barriers in their attempts to get a job and to maintain social relations. Based on the results, some of the respondents can be regarded as being socio-economically marginalised.

- BACKGROUND: The causes of prostate cancer are poorly understood, but genetic factors may be more important than for many other malignancies, and dietary phytoestrogens may be protective. Because phytoestrogens bind tightly to the estrogen receptor-beta, we conducted an epidemiologic investigation of synergistic effects between phytoestrogen intake and estrogen receptor-beta gene polymorphisms. METHODS: We performed a population-based case-control study in Sweden. All participants reported their phytoestrogen intake and donated a blood sample. We identified four haplotype-tagging single nucleotide polymorphisms (htSNPs) and genotyped these htSNPs in 1314 prostate cancer patients and 782 controls. Odds ratios were estimated by multivariate logistic regression. Interactions between phytoestrogen intake and estrogen receptor-beta SNPs on prostate cancer risk were evaluated considering both multiplicative and additive effect scales. RESULTS: We found a significant multiplicative interaction (P = 0.04) between dietary intake of phytoestrogens and a promoter SNP in the estrogen receptor-beta gene (rs 2987983-13950), but not with any of the three other htSNPs (P = 0.11, 0.69, 0.85). Among carriers of the variant promoter alleles, we found strong inverse associations with increasing intake of total phytoestrogens (odds ratio for highest vs. lowest quartile = 0.43; P for trend <0.001), isoflavonoids (odds ratio = 0.63; P for trend = 0.05), and coumestrol (odds ratio = 0.57; P for trend = 0.003). We found no association between phytoestrogens and prostate cancer among carriers homozygous for the wild-type allele (TT). CONCLUSIONS: Our study provides strong evidence that high intake of phytoestrogens substantially reduce prostate cancer risk among men with specific polymorphic variation in the promoter region of the estrogen receptor-beta gene.

- OBJECTIVE: Based on evidence that phytoestrogens may protect against prostate cancer, we evaluated the associations between serum enterolactone concentration or dietary phytoestrogen intake and risk of prostate cancer. METHODS: In our Swedish population-based case-control study, questionnaire-data were available for 1,499 prostate cancer cases and 1,130 controls, with serum enterolactone levels in a sub-group of 209 cases and 214 controls. Unconditional logistic regression was performed to estimate multivariate odds ratios (ORs) and 95% confidence intervals (CIs) for associations with risk of prostate cancer. RESULTS: High intake of food items rich in phytoestrogens was associated with a decreased risk of prostate cancer. The OR comparing the highest to the lowest quartile of intake was 0.74 (95% CI: 0.57-0.95; p-value for trend: 0.01). In contrast, we found no association between dietary intake of total or individual lignans or isoflavonoids and risk of prostate cancer. Intermediate serum levels of enterolactone were associated with a decreased risk of prostate cancer. The ORs comparing increasing quartiles of serum enterolactone concentration to the lowest quartile were, respectively, 0.28 (95% CI: 0.15-0.55), 0.63 (95% CI: 0.35-1.14) and 0.74 (95% CI: 0.41-1.32). CONCLUSIONS: Our results support the hypothesis that certain foods high in phytoestrogens are associated with a lower risk of prostate cancer.

Tidskriftsartikel (refereegranskat)abstract
- In Sweden, older adults are living and being cared for under the responsibility of their respective community. Extensive reorganizations in the community led to management having different backgrounds, which may have caused uncertainty among community nurses, especially in decision-making processes. The aim was to understand how 10 nurses, 10 doctors and 10 home care assistants as leaders for the nurses conceptualized the decision-making processes of community nurses, when referring older persons to Emergency Departments, and whether perceptual differences and/or similarities exist. Narrative interviews and content analysis were performed. The managers had differing views, but all felt there was a need to feel secure in order to trust professional decisions as being correct, thus avoiding inappropriate referrals. Management could see nurses' exposed position, but had varying solutions. This might lead to different messages being given regarding what is important and might explain why the nurses reported that the managers did not understand them.
