In this paper we propose a Bayesian nonparametric model for clustering partial ranking data. We start by developing a Bayesian nonparametric extension of the popular Plackett–Luce choice model that can handle an infinite number of choice items. Our framework is based on the theory of random atomic measures, with the prior specified by a completely random measure. We characterise the posterior d...

Forty-five men (18-35 years) trained three times a week for eight weeks to determine the effects of four constant-resistant weight training programmes on muscular strength, endurance, body composition and cardiovascular functioning. Subjects were randomly assigned to one of four programmes: Endurance (2 sets of 15 repetition maximum [RM]); Explosive (1 set of 15 RM); Strength 1 (3 sets of 6 RM)...

International organisations have started to shift from ‘agricultural’ to ‘rural’ focus in their programmes and Extension’s success in future may not be judged in terms of technology transfer or agricultural development alone.

A growing body of scientific evidence indicates that the declining levels of physical activity and fitness in children and youth are associated with adverse impacts on their health, including rising levels of obesity, diabetes, heart disease, metabolic syndrome and increased risk of sports injury. In response, a number of governmental and non-governmental organisations have instituted programme...

The paper describes emerging strategies employed by extension and continuing education units as they adapt to changes in the university and the larger community. The cost-recovery, entrepreneurial model of continuing education, relatively greater emphasis on continuing professional development programs, less emphasis on the traditional service function, the application of distance education tec...

The purpose of this study was therefore to make a qualitative investigation on the contribution of pre service agricultural education training programmes to the teaching of high school Agr...
