- DRM could be the solution to the content industry’s P2P dilemma, but content owners’ desire to monitor and control the consumer’s use of content can be perceived as an intrusion of privacy. High control makes consumers less active and low control invites them to experiment and to gain experience. Digital music files can easily be spread. Therefore legal services prefer keeping control over the music. This study reveals that consumers are one step ahead of the content industry, finding ways to circumvent protection and laws, and that the music industry is awaiting the "right" DRM business model. Online Music sellers basically rely on B2C DRM business models, but attempts have been made with C2C models, using consumers as distributors, and ISP models, where ISPs pay to collecting societies for all file trans-fers of copyrighted material in their networks. Future models include licensing mod-els, micro models, and no copyright at all.

- Alternate living, i.e. children living 50-50 with their parents following separation is emerging as a new family form. This study is the first to differentiate separated mothers with sole/main custody from mothers with alternately living children, analysing health outcomes and using a sample representative of the population. The association between the self-rated health (SRH) of mothers and different family structures are examined. Parental cooperation is included in the analyses as a potential mediator. Data on 755 mothers from the 2010 Swedish Level of Living Survey were analyzed by multivariate logistic regression. Single mothers with sole/main custody reported poorer SRH than couple mothers in intact families while the difference was not significant for single mothers with children living alternately and mothers in stepfamilies. Controlling for potential confounders, probabilities for poor SRH for single mothers were reduced. The excess risk among mothers with sole/main custody may be due to poorer socioeconomic conditions. Employment was significantly more common among mothers with alternate living and an important explanatory factor for their better health compared to single mothers with sole/main custody. Adjusting for parental cooperation lowered the increased probability for poor SRH among single mothers with sole/main custody compared to single mothers with alternate living.

Child living arrangements following separation and mental health of parents in Sweden

Tidskriftsartikel (refereegranskat)abstract
- Father involvement and joint physical custody in post-separation families are increasingly common. In Sweden, 35 percent of the children of separated parents live equally much with both parents. Since parenthood is gendered, the associations between child living arrangement and parental health may vary between women and men. This study analyzes the association between children's living arrangement and mental health of parents, and how this interacts with material and social circumstances. Drawing on The Swedish Survey of Living Conditions (ULF) 2008-2013, the association between child living arrangements and mental health (worry/anxiety) of parents in five family structures: two biological parents, reconstituted with joint or main/sole custody arrangements, single with joint physical custody, and single with main or sole custody, were analyzed. Data on 9,225 mothers and fathers with resident children aged 0-17 were analyzed by logistic regressions for average marginal effects adjusting for socio-demographic, socio-economic and social factors. Analyses of interaction effects were made using the synergy index. Substantial family type differences were found in mental health between two biological parent family and all other family types for mothers, and two biological parent family and single parents for fathers. For the single mothers, the higher risk for worry and anxiety was still found following controls for socioeconomic factors. For fathers, the only differences that remained following control for socioeconomic factors was that of single fathers with children in joint physical custody. Interaction effects were found for the combination of single motherhood and non-employment, indicating a higher risk of mental health problems for single mothers (both with joint and sole custody), than would be expected from a simple addition of these exposures, suggesting that this is a vulnerable group. The results indicate that joint custody is associated with higher risk for worry and anxiety for the parents, especially for mothers both re-partnered and single, but also for single fathers.

- OBJECTIVE To evaluate the cross-cultural validity of the Demand-Control Questionnaire, comparing the original Swedish questionnaire with the Brazilian version. METHODS We compared data from 362 Swedish and 399 Brazilian health workers. Confirmatory and exploratory factor analyses were performed to test structural validity, using the robust weighted least squares mean and variance-adjusted (WLSMV) estimator. Construct validity, using hypotheses testing, was evaluated through the inspection of the mean score distribution of the scale dimensions according to sociodemographic and social support at work variables. RESULTS The confirmatory and exploratory factor analyses supported the instrument in three dimensions (for Swedish and Brazilians): psychological demands, skill discretion and decision authority. The best-fit model was achieved by including an error correlation between work fast and work intensely (psychological demands) and removing the item repetitive work (skill discretion). Hypotheses testing showed that workers with university degree had higher scores on skill discretion and decision authority and those with high levels of Social Support at Work had lower scores on psychological demands and higher scores on decision authority. CONCLUSIONS The results supported the equivalent dimensional structures across the two culturally different work contexts. Skill discretion and decision authority formed two distinct dimensions and the item repetitive work should be removed.

Variations in Patients' Overall Assessment of Their Health Across and Within Disease Groups Using the EQ-5D Questionnaire: Protocol for a Longitudinal Study in the Swedish National Quality Registers

- Background: EQ-5D is one of the most commonly used questionnaires to measure health-related quality of life. It is included in many of the Swedish National Quality Registers (NQRs). EQ-5D health states are usually summarized using "values" obtained from members of the general public, a majority of whom are healthy. However, an alternative, which remains to be studied in detail, is the potential to use patients' self-reported overall health on the visual analog scale (VAS) as a means of capturing experience-based perspective. Objective: The aim of this study is to assess EQ VAS as a valuation method with an experience-based perspective through comparison of its performance across and within patient groups, and with that of the general population in Sweden. Methods: Data on nearly 700,000 patients from 12 NQRs covering a variety of diseases/conditions and nearly 50,000 individuals from the general population will be analyzed. The EQ-5D-3L data from the 12 registers and EQ-5D-5L data from 2 registers will be used in the analyses. Longitudinal studies of patient-reported outcomes among different patient groups will be conducted in the period from baseline to 1-year follow-up. Descriptive statistics and analyses comparing EQ-5D dimensions and observed self-assessed EQ VAS values across and within patient groups will be performed. Comparisons of the change in health state and observed EQ VAS values at 1-year follow-up will also be undertaken. Regression models will be used to assess whether EQ-5D dimensions predict observed EQ VAS values to investigate patient value sets in each patient group. These will be compared across the patient groups and with the existing Swedish experience-based VAS and time trade-off value sets obtained from the general population. Results: Data retrieval started in May 2019 and data of patients in the 12 NQRs and from the survey conducted among the general population have been retrieved. Data analysis is ongoing on the retrieved data. Conclusions: This research project will provide information on the differences across and within patient groups in terms of self-reported health status through EQ VAS and comparison with the general population. The findings of the study will contribute to the literature by exploring the potential of self-assessed EQ VAS values to develop value sets using an experience-based perspective.
