  abstract  = {World Bank evaluations show that recipient performance varies substantially between different projects. Extant research has focused on country-level variables when explaining these variations. This article goes beyond country-level explanations and highlights the role of World Bank staff. We extend established arguments in the literature on compliance with the demands of International Organizations (IOs) and hypothesize that IO staff can shape recipient performance in three ways. First, recipient performance may be influenced by the quality of IO staff monitoring and supervision. Second, the leniency and stringency with which IO staff apply the aid agreement could improve recipient performance. Third, recipient performance may depend on whether IO staff can identify and mobilize supportive interlocutors through their networks in the recipient country. We test these arguments by linking a novel database on the tenure of World Bank task team leaders to projects evaluated between 1986 and 2020. The findings are consistent with the expectation that World Bank staff play an important role, but only in investment projects. There is substantial evidence that World Bank staff supervisory ability and country experience are linked to recipient performance in those projects. Less consistent evidence indicates that leniency could matter. These findings imply that World Bank staff play an important role in facilitating implementation of investment projects.},

  abstract  = {Objective: The purpose of this systematic review and meta-analysis was to examine the effects of exercise on depression and anxiety in people living with HIV (PLWH), and to evaluate, through subgroup analysis, the effects of exercise type, frequency, supervision by exercise professionals, study quality, and control group conditions on these outcomes. Method: A literature search was conducted through four electronic databases from inception to February 2019. Considered for inclusion were randomized controlled trials (RCTs) investigating exercise interventions and depression or anxiety as outcomes in people living with HIV (>= 18 years of age). Ten studies were included (n = 479 participants, 49.67\% females at baseline), and the standardized mean difference (SMD) and heterogeneity were calculated using random-effect models. An additional pre-post meta-analysis was also conducted. Results: A large effect in favor of exercise when compared to controls was found for depression (SMD = -0.84, 95\%CI = [-1.57, -0.11], p = 0.02) and anxiety (SMD = -1.23, 95\%CI = [-2.42, 0.04], p = -0.04). Subgroup analyses for depression revealed large effects on depression for aerobic exercise only (SMD = -0.96, 95\%CI = [-1.63, -0.30], p = 0.004), a frequency of >= 3 exercise sessions per week (SMD = -1.39, 95\%CI = [-2.24, -0.54], p < 0.001), professionally supervised exercise (SMD = -1.40, 95\%CI = [-2.46, -0.17], p = 0.03]), and high-quality studies (SMD = -1.31, 95\%CI = [-2.46, -0.17], p = 0.02). Conclusion: Exercise seems to decrease depressive symptoms and anxiety in PLWH, but other larger and high-quality studies are needed to verify these effects.},

  abstract  = {Background: Although clinical supervision is considered to be a major component of the development and maintenance of psychotherapeutic competencies, and despite an increase in supervision research, the empirical evidence on the topic remains sparse. Methods: Because most previous reviews lack methodological rigor, we aimed to review the status and quality of the empirical literature on clinical supervision, and to provide suggestions for future research. MEDLINE, PsycInfo and the Web of Science Core Collection were searched and the review was conducted according to current guidelines. From the review results, we derived suggestions for future research on clinical supervision. Results: The systematic literature search identified 19 publications from 15 empirical studies. Taking into account the review results, the following suggestions for further research emerged: Supervision research would benefit from proper descriptions of how studies are conducted according to current guidelines, more methodologically rigorous empirical studies, the investigation of active supervision interventions, from taking diverse outcome domains into account, and from investigating supervision from a meta-theoretical perspective. Conclusions: In all, the systematic review supported the notion that supervision research often lags behind psychotherapy research in general. Still, the results offer detailed starting points for further supervision research.},
