Dieses Buch liefert einen aktuellen Überblick über die Formen, die Häufigkeit und die Auswirkungen sexueller Gewalterfahrungen Jugendlicher: Wer ist betroffen von sexueller Gewalt? Wer ist Täter_in? Wo findet sexuelle Gewalt statt? Die vorgestellte Studie gibt Lehrer_innen und anderen pädagogischen Fachkräften Antworten auf diese und weitere Fragen – unter anderem aus der Perspektive von direkt Betroffenen, Beobachter_innen sowie Jugendlichen, die sexuelle Gewalt ausüben. Ein besonderes Augenmerk liegt auf dem schulischen Kontext: Hier zeigen sich bestimmte Formen sexueller Gewalt besonders häufig. Gleichzeitig ist die Schule der Ort, an dem alle Jugendlichen zusammenkommen und der sich daher für Präventionsarbeit im Besonderen eignet. Dazu stellt das Buch die Grundzüge des aus den Ergebnissen abgeleiteten Präventionsansatzes SEPP – Sensibilisierende Prävention durch Partizipation – vor.

An implementation analysis conducted as part of a 2-year experimental study of residential and nonresidential treatment programs for the dually diagnosed homeless found significant differ ences in client engagement and retention, as well as unexpected variations in the treatment conditions. Fully 40% of subjects assigned to either treatmentfailed to become engaged for even one day, although a significantly higher percentage of those assigned to the residential program than the nonresidential program graduated from the first 3-month phase of treatment. The analysis revealed significant differences in the type and amount of services provided by the two treatment programs, as well as potentially important difficulties in program management. Such process data are valuable toolsfor understanding client outcomes and interpreting experimental results.

As many regions in sub-Saharan Africa, the border region of Kenya (KE) and Uganda (UG) has faced a declining soil fertility for decades, resulting from soil erosion, intensely managed agricultural soils due to population pressure and small inputs of mineral and organic fertilizers. With limited financial means, farmers need measures and/or technologies that effectively reduce nutrient losses or increase inputs at a low cost. In this study, four such measures are in focus, namely erosion reduction practices, vermicomposting of animal manure, collection of human urine in jerry cans and, collection of human excreta in urine-diverting dry toilets. Current soil nutrient balances in five districts in the Sio-Malaba-Malakisi River Basin and the potential of these measures to reduce the soil nutrient deficit are studied using the method of material flow analysis and the software STAN. Furthermore, crop-nutrient-response functions are used to determine their potential impact on maize harvests. Overall, results reveal that there exists a non-negligible and exploitable potential of local resources to reduce the soil nutrient deficit, improve harvests and in turn food security of the smallholder farmers in the region. Soil nutrient deficits could be reduced by 20–30%, 23–42% and 9–15% for nitrogen (N), phosphorus (P) and potassium (K), respectively. Subsequently, maize harvests could be increased by 8–40%, depending on the applied technology and area. This research provides useful insights for agricultural extension workers, politicians and researchers alike, highlighting that simple and easily available technologies can harness similar amounts of nutrients as more complex and expensive ones if all specific technology-constraints are adequately incorporated in the analyses. ; 1 ; 17 ; 17

Background: The COVID-19 pandemic has disrupted routine hospital services globally. This study estimated the total number of adult elective operations that would be cancelled worldwide during the 12 weeks of peak disruption due to COVID-19. Methods: A global expert response study was conducted to elicit projections for the proportion of elective surgery that would be cancelled or postponed during the 12 weeks of peak disruption. A Bayesian β-regression model was used to estimate 12-week cancellation rates for 190 countries. Elective surgical case-mix data, stratified by specialty and indication (surgery for cancer versus benign disease), were determined. This case mix was applied to country-level surgical volumes. The 12-week cancellation rates were then applied to these figures to calculate the total number of cancelled operations. Results: The best estimate was that 28 404 603 operations would be cancelled or postponed during the peak 12 weeks of disruption due to COVID-19 (2 367 050 operations per week). Most would be operations for benign disease (90·2 per cent, 25 638 922 of 28 404 603). The overall 12-week cancellation rate would be 72·3 per cent. Globally, 81·7 per cent of operations for benign conditions (25 638 922 of 31 378 062), 37·7 per cent of cancer operations (2 324 070 of 6 162 311) and 25·4 per cent of elective caesarean sections (441 611 of 1 735 483) would be cancelled or postponed. If countries increased their normal surgical volume by 20 per cent after the pandemic, it would take a median of 45 weeks to clear the backlog of operations resulting from COVID-19 disruption. Conclusion: A very large number of operations will be cancelled or postponed owing to disruption caused by COVID-19. Governments should mitigate against this major burden on patients by developing recovery plans and implementing strategies to restore surgical activity safely.
