BACKGROUND Several epidemiological studies have investigated the association between occupation and brain tumour risk, but results have been inconclusive. We investigated the association between six occupational categories defined a priori: chemical, metal, agricultural, construction, electrical/electronic and transport, and the risk of glioma, meningioma and acoustic neuroma. METHODS In a po...

This paper draws upon development economics theory, demographic projections, and empirical evidence to consider the likely consequences of the HIV/AIDS pandemic for the agricultural sector of the hardest-hit countries of Eastern and Southern Africa. We identify four processes that have been underemphasized in previous analysis: 1) the momentum of long-term population growth rates; 2) substantia...

OBJECTIVES To describe work related fatal injuries to agricultural workers in New Zealand to identify priority areas for further research and injury control measures. METHODS Injury deaths in New Zealanders aged 15-84 inclusive for the period 1985-94 were identified and the coroner's files for these obtained. These files were then reviewed to determine whether the death arose as a result of w...

Science and technology parks have been a major driver of both the commercialization of agricultural innovation and the financial success of many farm and agribusiness firms. Therefore, the main purpose of this study was to explain the factors affecting commercialization of agricultural innovation in Kermanshah Science and Technology Park. The experts of this center were sampled by the census me...

This paper addresses the issue of self-selection of individuals in international labour migration, non-agricultural and agricultural employment in Tajikistan and its link to earnings from these activities. Unlike most empirical studies, we could attribute selection bias on unobservable characteristics to the allocation of individuals to alternative employment sectors and analyse its impact on e...

Kenya is an exciting case for those who suspect that agriculture has powerful linkages with the rest of the economy. Over the period 1965-87 Kenya's agricultural production consistently surpassed the average for Sub-Saharan Africa. The same was true of its manufacturing and services (see World Bank 1989, table 7.1). One possible explanation for this performance is that agricultural growth stimu...

In the literature of new trade theory, most studies have dealt with industrial location by imposing an assumption of free transportation in the agricultural sector. We explicitly incorporate arbitrary transport costs in both the manufacturing and agricultural sectors into the Helpman-Krugman-Davis model of two countries and one production factor. The following results are obtained. First, we fi...
