Care-leavers – those transitioning from alternative care towards young adulthood – are widely recognized as a vulnerable population, yet child protection legislation seldom applies to them because they have reached adulthood. Despite this, little internationally comparative research on care-leaving policy and legislation has been conducted. This paper maps multinational policy and legislation and its impact on the services to care-leavers and the challenges they experience. An online survey was conducted with key informants in 36 countries and analysed by a multinational team of care-leaving scholars. Findings reveal that few countries have well-developed care-leaving legislation. Most countries provide little aftercare beyond the age of 18, even when legislation provides for it. Within the context of suboptimal social policy and limited aftercare services, findings also reveal high vulnerability among care-leavers. Recommendations for policy development, global dialogue, further research and advocacy are proposed.

Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis, with the consequent hypercortisolism, is one of the most consistent findings in chronic stress and depression. The stress response will depend on characteristics of stressors, their subjective appraisal and the resulting coping strategies. The aim of this study was to evaluate the efficacy of cognitive therapy (CT) in the treatment of a chronic stress condition, such as generalized anxiety disorder (GAD), as it would be reflected through both psychological and biological parameters. For this purpose, a group of outpatients with GAD were treated with CT for up to a maximum of 24 sessions. In order to assess psychological and biological changes, anxiety-related symptoms were evaluated according to the Hamilton Anxiety Rating Scale (HAM-A), and the HPA function was determined through assessment of circulating cortisol levels.

Upon completion of the treatment, a significant decrease in HAM-A scores, along with significant changes in plasma cortisol levels, were observed in treated subjects. These observations contribute to demonstrate that CT may be effective to treat a chronic stress disorder, such as GAD, as it was observed at both psychological and biological levels, and moreover, this could represent an effective approach to treat hypercortisolism due to hyperactivity of the HPA axis. Therapeutic and preventive strategies will also be discussed.

Eclosion times and rates of Rhagoletis tabellaria (Fitch) (Diptera: Tephritidae) and its parasitoid wasp Utetes tabellariae (Fischer) (Hymenoptera: Braconidae) held at different chilling durations were determined in the laboratory. Adult fly and wasp longevity were also determined. Adult female and male flies from R. tabellaria puparia chilled for 195 days at 4.8 °C and then held at 23.2 °C eclosed on average earlier than U. tabellariae reared from R. tabellaria puparia. Rhagoletis tabellaria also eclosed significantly earlier from puparia chilled for 150 days than 120 days at 2.7 °C, but U. tabellariae eclosion from the two treatments did not differ significantly. Rhagoletis tabellaria eclosion rates were greater with longer chill durations, but U. tabellariae eclosion rates per R. tabellaria puparium did not differ among chill durations. No R. tabellaria eclosed from nonchilled puparia held at 20–22 °C, but at least 18.8% of nonchilled U. tabellariae eclosed. Female and male R. tabellaria on average survived 52.1 and 83.3 days, respectively, while female and male U. tabellariae survived 37.7 and 28.7 days, respectively. Results indicate diapause and developmental traits of R. tabellaria may be more dependent on chilling durations and less flexible than those of U. tabellariae, a wasp that appears adapted to flies in the R. tabellaria species complex.

The homo- and heteroepitaxial deposition of LGS (langasite, La3Ga5SiO14) thin films on LGS single crystals, Si and SiO2 substrates by pulsed laser deposition (PLD) is demonstrated. PLD is performed at substrate temperatures up to about 700 °C and results initially in Ga deficient films. Two strategies of counterbalancing the Ga deficit are realized. First, off-stoichiometric targets with an enhanced Ga content are applied. Secondly, an increased oxygen partial pressure up to about 6 Pa is used during deposition to suppress evaporation of Ga suboxides. Combining these adaptions results in the growth of stoichiometric LGS thin films. Films deposited on LGS substrates do not show any additional X-ray diffraction reflexes nor broadening of the peaks with respect to the single crystalline substrates. Therefore, the homoepitaxial approach can be considered successful. The deposition on Si and SiO2 substrates under the same conditions leads to the formation of polycrystalline films. However, post-annealing at 800 °C increases crystallinity. Stoichiometry and homogeneous distribution of La, Ga and Si cations are confirmed by secondary neutral mass spectrometry (SNMS). The composition remains constant within the film, implying stable process parameters.
