This article aims to identify and examine the key factors in effective recruitment for people to work successfully overseas. It investigates key factors such as experience of working overseas, attitude and personality which determine the success or failure of people recruited to work in education in developing countries; from personal reasons for seeking such work and the appropriate recruitment process, to the induction and how expatriates settle in to their work and life in a very different culture and working environment. The ‘culture shock’ experienced on arrival is studied to reflect on how its effects may be lessened. Three case studies illuminate specific lessons that can be learned where there is evidence of match or mismatch between expatriate and employing organization. 相似文献

Peer assessment is very various in its implementation. Six studies of peer assessment are reviewed, four of them in higher education. A literature review is followed by five empirical studies. Strengths and weaknesses of each study are considered and issues are raised. Variables in peer assessment needing further exploration are extricated – in sample definition, specification of type of peer assessment, organisational nature of the intervention, and the measures which are used to evaluate change. It is suggested that further experimental and quasi-experimental studies are necessary to contrast one or two of these variables at a time. 相似文献

The speed at which a player can swing a bat is central to the games of baseball and softball, determining, to a large extent,
the hit speed of the ball. Experimental and analytical studies of bat swing speed were conducted with particular emphasis
on the influence of bat moment of inertia on swing speed. Two distinct sets of experiments measured the swing speed of colege
baseball and fast-pitch softball players using weighted rods and modified bats. The swing targets included flexible targets,
balls on a tee and machine pitched balls. Internal mass alterations provided a range of inertial properties. The average measured
speeds, from 22 to 31 m s−1, are consistent with previous studies. Bat speed approximately correlates with the moment of inertia of the bat about a vertical
axis of rotation through the batter's body, the speed generally decreasing as this moment of inertia increases. The analytical
model assumes pure rotation of the batter/bat system about a vertical axis through the batter's body. Aerodynamic drag of
the batter's arms and the bat is included in the model. The independent variable is bat moment of inertia about the rotation
axis. There is reasonable agreement between the model and the measured speeds. Detailed differences between the two suggest
the importance of additional degrees of freedom in determining swing speed. 相似文献
