The objective interpretation of histopathological data: an application to the ageing of ovine bruises

Muscle and adipose tissue from a total of 178 experimental bruises inflicted on sheep and aged from 1 to 72 h old were processed for light microscopic examination. Five observed histopathological features of inflammation and repair were scored semiquantitatively on a scale of 1-4 according to their degrees of change from the normal state. These data were evaluated mathematically using a Bayesian probability model designed for the purpose. The model was able to age bruises with an acceptable degree of accuracy only as either 1-20 h or 24-72 h old but within these constraints a degree of confidence in excess of 90% was achieved. The exact performance of the model depended on the nature and number of tissue samples examined but mathematical ageing was superior to interpretative ageing based on personal experience.     

Evaluation of the Education Sector Enhancement Program in Barbados

ABSTRACT

Drawing on the education production function literature, we examine the short-run impact of comprehensive education reforms in Barbados on primary school student outcomes. Using a variety of specifications to test the robustness of our results, we find modest and mixed changes in student test scores. Our findings are discussed in the context of management challenges that resulted from the need to coordinate a multi-faceted project in a rapidly developing nation; alignment of goals and schedules of two multi-national development banks, the Ministry of Education, Youth Affairs and Sports (MES), and the Government of Barbados; and, a very rapidly changing information technology environment that led, in part, to changes in planned capital improvements in schools, equipment needs, and had implications for teacher training.     

Asian workers in the Gulf states of the Middle East

One of the most conspicuous developments in recent years in the Korean political economy is the enormous increase of Korean investment in Southeast Asia, especially Indonesia. In particular, since the appreciation of the Korean currency (won) in 1987 and the rapid increase of industrial action by Korean workers, more Korean foreign direct investment (FDI) has been carried out by small-and medium-sized firms, particularly in the manufacturing sector. However, many of the Korean firms in the region have already experienced various problems. This article examines the determinants of the new phase of Korean FDI. It also discusses the possible consequences of Korean FDI in Indonesia.
