Relativistic Mean Field Approximation in a Density Dependent Parametrization Model at Finite Temperature

In this work we calculate the equation of state of nuclear matter for different proton fractions at zero and finite temperature within the Thomas Fermi approach considering three different parameter sets: the well-known NL3 and TM1 and a density dependent parametrization proposed by Typel and Wolter. The main differences are outlined and the consequences of imposing beta-stability in these models are discussed.Comment: 13 pages, 10 figure

Towards a new understanding of cohabitation: Insights from focus group research across Europe and Australia

Background: Across the industrialized world, more couples are living together without marrying. Although researchers have compared cohabitation cross-nationally using quantitative data, few have compared union formation using qualitative data. Objective: We use focus group research to compare social norms of cohabitation and marriage in Australia and nine countries in Europe. We explore questions such as: what is the meaning of cohabitation? To what extent is cohabitation indistinguishable from marriage, a prelude to marriage, or an alternative to being single? Are the meanings of cohabitation similar across countries? Methods: Collaborators conducted seven to eight focus groups in each country using a standardized guideline. They analyzed the discussions with bottom-up coding in each thematic area. They then collated the data in a standardized report. The first and second authors systematically analyzed the reports, with direct input from collaborators. Results: The results describe a specific picture of union formation in each country. However, three themes emerge in all focus groups: commitment, testing, and freedom. The pervasiveness of these concepts suggests that marriage and cohabitation have distinct meanings, with marriage representing a stronger level of commitment. Cohabitation is a way to test the relationship, and represents freedom. Nonetheless, other discourses emerged, suggesting that cohabitation has multiple meanings. Conclusions: This study illuminates how context shapes partnership formation, but also presents underlying reasons for the development of cohabitation. We find that the increase in cohabitation has not devalued the concept of marriage, but has become a way to preserve marriage as an ideal for long-term commitment

Participation and satisfaction after spinal cord injury: results of a vocational and leisure outcome study

Study design: Survey. Objectives: Insight in (1) the changes in participation in vocational and leisure activities and (2) satisfaction with the current participation level of people with spinal cord injuries (SCIs) after reintegration in society. Design: Descriptive analysis of data from a questionnaire. Setting: Rehabilitation centre with special department for patients with SCIs, Groningen, The Netherlands. Subjects: A total of 57 patients with traumatic SCI living in the community, who were admitted to the rehabilitation centre two to 12 years before the current assessment. Main outcome measures: Changes in participation in activities; current life satisfaction; support and unmet needs. Results: Participation expressed in terms of hours spent on vocational and leisure activities changed to a great extent after the SCI. This was mainly determined by a large reduction of hours spent on paid work. While 60% of the respondents successfully reintegrated in work, many changes took place in the type and extent of the job. Loss of work was partially compensated with domestic and leisure activities. Sports activities were reduced substantially. The change in participation level and compensation for the lost working hours was not significantly associated with the level of SCI-specific health problems and disabilities. As was found in other studies, most respondents were satisfied with their lives. Determinants of a negative life satisfaction several years following SCI were not easily indicated. Reduced quality of life was particularly related to an unsatisfactory work and leisure situation. Conclusions: Most people with SCI in this study group were able to resume work and were satisfied with their work and leisure situation
