作者： Charles B. Moss Samba Mbaye james f. Oehmke food and Resource Economics Department University of Florida Gainesville FL USA Department of Economics and Management Scienes Universite Gaston Berger de Saint Louis Saint Louis Senegal United States Agency for International Development Washington DC USA

This paper develops an information theoretic estimator of wage and employment shifts that provides quantification of and inference about type of employment (full time, part time, seasonal, unemployed) and industry share of employment. It is applied to determine the effects of two United States Agency for International Development (USAID) projects on employment in villages in the Tambacounda and Kedougou provinces in Senegal. The projects support the development of local forest-based production and processing industries. The results demonstrate statistically significant and positive effects on employment and the industry composition of employment.

There is some evidence to suggest superior results of surgical treatment that includes open reduction internal fixation (ORIf) or percutaneous pin fixation (not including Kapandji pinning) to stabilize fracture fragments and improve functional ability compared with conservative treatment. However, larger studies with longer follow up are needed to verify these results.
