Composition and conservation value of bird assemblages of urban ‘habitat islands’: Do pedestrian traffic and landscape variables exert an influence?

Urban forest fragments can potentially be ‘habitat islands’ for native birds, but pedestrian traffic could influence the composition and conservation value of their bird assemblages by reducing the representation of disturbance-sensitive species. Winter bird assemblages and pedestrian traffic rates were documented in twelve forested parks in suburban Melbourne, Australia. Native birds comprised 87% of sightings, but two exotic species were common. Bird species' distribution among the parks was significantly nested. However, park rank orders for bird assemblage nestedness and mean pedestrian traffic rate were not correlated and only one species' distribution was nested with respect to this variable. The observed correlation between park area and bird assemblage nestedness may have been partly due to passive sampling. Degree of isolation of parks influenced nestedness less than park area. Forested parks provided habitat for species that occur at intermediate to low densities in other suburban habitats and for ecological specialists otherwise rare in suburbia. Larger parks contained more species than, and many of the native species found in, smaller parks. However, smaller parks each had 25% of the native bird species inhabiting the suite of fragments and thus had both aesthetic value and some potential to enhance city-dwellers' awareness about biodiversity conservation.     

Self-rated quality of life among the young unemployed and the young in work in northern Sweden

This study analysed self-assessed quality of life (QoL), using a QoL questionnaire (H?rnquist's QLcs) covering life spheres, somatic health, mental well-being, cognitive ability, social and family life, activity, financial situation, meaning in life and a global score "entire life", for young people aged 18-24 in a population-based cross-sectional study in northern Sweden. Of these, 651 were unemployed and 2802 were in work (employed, students and in military service). Results showed that the young unemployed exhibited poorer QoL than the young in work and the greatest difference was found regarding their financial situation. Young men rated somatic health and mental well-being higher than young women. However, QoL in other essential domains was rated higher by young women in work. Close friends and money reserve were important for all participants, no matter whether they were employed or not. The risk of being young and unemployed was greater if the person had a worse financial situation, shorter education, and fewer leisure activities with other people. Finally, it was concluded that while QoL is poorer when in unemployment - both for the young and those who are older (aged 25-64) - psychological well-being, in contrast to several previous studies, is even poorer for young people than for those who are older. This is worrying in a public health perspective and could have implications for unemployment policies for younger and less well-educated age groups.     

Maintaining professional integrity: experiences of case workers performing the assessments that determine children’s access to personal assistance

This qualitative study explores Swedish case workers experiences of decision making regarding disabled children's right to obtain assistance in their everyday life whereby they can live independently in the community. Data collection included seven focus-group interviews and 11 complementary individual interviews with case workers from different agencies responsible for decisions regardig access to personal assistance. Grounded theory methodology was used. Compromised professional integrity under shifting conditions emerged as a main concern and maintaing professional integrity was used as an approach to resolve it. The case workers are maintaining professional integrity by applying different strategies; struggling with division of responsibility, bureaucratizig, and justifying and protecting. The results indicate that present application of assessment criteria in combination with the utilization of precedent rulings has made it difficult for the case workers to make decisions that provide children access to assistance. Current practice raises questions about the case workers perspectives of professionalism.     

How to Maintain High Retention Rates in Long-Term Research on Addiction: A Case Report

High dropout rates threaten the validity of longitudinal studies involving participants suffering from substance use disorder (SUD). The objective of this article is to evaluate strategies to improve retention. The data analysis was based on an ongoing study of long-term recovery of neurocognitive and psychosocial functions. We used traditional strategies to enhance the contact rate. Common factors in psychosocial treatments and biweekly Short Message Service (SMS; text messaging) monitoring were added to further increase the contact rate. The participants (n = 146) were recruited from treatment facilities for SUD. Assessments were measured at 3 months, 6 months, 9 months, and 12 months. This study was successful in retaining a cohort of participants who are typically characterized as having a negative prognosis because of their unstable living arrangements and incomes. Compared to those using GHB, addictive medications, and opiates, the retention rate was the lowest among participants with severe alcohol use disorder (42%).
