Amblyomma variegatum and A. hebraeum are two ticks of veterinary and human health importance in south-east Africa. In Zimbabwe they occupy parapatric (marginally overlapping and juxtaposed) distributions. Understanding the mechanisms behind this parapatry is essential for predicting the spatio-temporal dynamics of Amblyomma spp. and the impacts of(More)

Does Job-Search Assistance Affect Search Effort and Outcomes? A Microeconometric Analysis of Public versus Private Search Methods In this paper, we examine the disincentive effects of the public employment service on the search effort of unemployed workers and on their exit rate from unemployment. For that purpose, we specify a structural search model with(More)
Existing exogeneity conditions of literature are only sufficient and imply “overly strong” constraints on long-run parameters. This paper presents some new results on exogeneity in VECM models. A key concept of the analysis is the “purely exogenous long-run path”, i.e. a cointegrating vector only including “exogenous” variables. Extending earlier results of(More)
Epidemiosurveillance networks face numerous challenges: diversity of diseases, farming practices and environment; language barriers; heterogeneity of socioeconomic development levels, health infrastructure and laboratory and epidemiology capacities; disparate veterinary legislation and health policies; and an increasing lack of human and funding resources.(More)
