Educational Assessment of Medical Student Rotation in Emergency Ultrasound

Background: Medical student ultrasound education is sparse. In 2002, we began the first medical student rotation in emergency ultrasound. Objective: To evaluate if medical students can learn and retain sonographic skills during a two- or four-week elective. Methods: We gave students an exam on the first and last days of the rotation. Six months later, students took the exam a third time. A control group was used for comparison. Results: Over a 19-month period, we enrolled 45 students (25 on the two-week and 20 on the four-week elective). The four-week student post-test score was significantly better than the two- week posttest score (81% vs. 72%, p=0.003). On the six-month exam, the four-week student post-test score was significantly better than the two-week post-test score (77% vs 69%, p=0.008). The control group did not statistically improve. Conclusion: Medical students can learn bedside ultrasound interpretation with clinical integration and retain the knowledge six months later

FDI and migration of skilled workers towards developing countries: Firm-level evidence from sub-saharan Africa

This article investigates the determinants of the employment of foreign skilled workers by firms operating in Sub-Saharan African countries. We use cross section firm-level data on a large sample of foreign and domestic firms collected through the Africa Investor Survey 2010 by the United Nations Industrial Development Organization. We find evidence of a strong complementarity between foreign capital inflows and the employment of foreign skilled workers. Our results also indicate that interventions in improving the working regulation and skilled workers immigration regimes may stimulate foreign skilled workers transfer by firms, and thereby foreign direct investments
