Formative research to develop an intervention for addressing mental health/psychosocial issues and HIV vulnerability of marginalized adolescents in Addis Ababa, Ethiopia

Children and adolescents who migrate from rural regions to Addis Ababa, Ethiopia often flee their households to escape from abusive families, forced marriages, poverty, lack of economic opportunity and education, and other social problems. They are often met with equally harsh, if not worse, challenges when they arrive in Addis Ababa, including treacherous living situations, abusive working conditions with meager compensation, limited opportunities for education and socialization, and absence of family support. This study conducted a qualitative needs assessment to determine type and extent of mental health and psychological needs among adolescent migrants living in Addis Ababa in order to develop a targeted psychosocial support intervention to address the identified needs. Semistructured in-depth interviews were conducted with 30 service recipients from Biruh Tesfa and Retrak, and 11 service providers from Biruh Tesfa, Retrak, and Organization for the Prevention, Rehabilitation and Integration of Female Street Children. Key findings revealed several high-risk situations that adolescent migrants in Addis Ababa are exposed to that specifically compromise their psychosocial well-being and increase their vulnerability to HIV

Internal-state thermometry by depletion spectroscopy in a cold guided beam of formaldehyde

We present measurements of the internal state distribution of electrostatically guided formaldehyde. Upon excitation with continuous tunable ultraviolet laser light the molecules dissociate, leading to a decrease in the molecular flux. The population of individual guided states is measured by addressing transitions originating from them. The measured populations of selected states show good agreement with theoretical calculations for different temperatures of the molecule source. The purity of the guided beam as deduced from the entropy of the guided sample using a source temperature of 150K corresponds to that of a thermal ensemble with a temperature of about 30 K

'Trust is good, control is better': the 1974 Herstatt-Bank crisis and its implications for international regulatory reform

With its international supervisory and regulatory implications, the failure of Bankhaus Herstatt is one of the landmarks of post-war financial history. This article offers the first comprehensive historical account of the Herstatt crisis, and contributes to the wider discussions on international supervisory and regulatory reform since the mid-1970s, including regulatory capture, markets' self-regulation and resolution of failed banks. In doing so, it first argues that contrary to a widely held view, the German authorities received early and repeated warnings about Herstatt's dealings but this involved only limited and ineffective regulatory/supervisory responses, then it turns to the actual collapse of the bank in June 1974, and finally explores the wider regulatory issues raised by the Herstatt case

RAPIDS evaluation final report 2005-2009 key findings

RAPIDS (Reaching HIV/AIDS Affected People with Integrated Development and Support) is an intervention funded by the United States Agency for International Development (USAID), and is designed to mitigate the impact of HIV/AIDS in Zambia. The overall goal of RAPIDS is to improve the quality of life of Zambians affected by HIV and AIDS by expanding successful community-based models of home-based care and support to orphans and vulnerable children and people who are chronically ill, as well as through interventions targeting youth with livelihood opportunities and life-skills training, focusing on initiatives supporting abstinence and being faithful

Small crater populations on Vesta

The NASA Dawn mission has extensively examined the surface of asteroid Vesta, the second most massive body in the main belt. The high quality of the gathered data provides us with an unique opportunity to determine the surface and internal properties of one of the most important and intriguing main belt asteroids (MBAs). In this paper, we focus on the size frequency distributions (SFDs) of sub-kilometer impact craters observed at high spatial resolution on several selected young terrains on Vesta. These small crater populations offer an excellent opportunity to determine the nature of their asteroidal precursors (namely MBAs) at sizes that are not directly observable from ground-based telescopes (i.e., below ~100 m diameter). Moreover, unlike many other MBA surfaces observed by spacecraft thus far, the young terrains examined had crater spatial densities that were far from empirical saturation. Overall, we find that the cumulative power-law index (slope) of small crater SFDs on Vesta is fairly consistent with predictions derived from current collisional and dynamical models down to a projectile size of ~10 m diameter (Bottke et al., 2005a,b). The shape of the impactor SFD for small projectile sizes does not appear to have changed over the last several billions of years, and an argument can be made that the absolute number of small MBAs has remained roughly constant (within a factor of 2) over the same time period. The apparent steady state nature of the main belt population potentially provides us with a set of intriguing constraints that can be used to glean insights into the physical evolution of individual MBAs as well as the main belt as an ensemble.Comment: Accepted by PSS, to appear on Vesta cratering special issu
