Animals may respond to habitat quality and habitat edges and these responses may affect their distribution between habitats. We studied the movement behaviour of a ground-dwelling generalist predator, the carabid beetle Pterostichus melanarius (Illiger). We performed a mark-recapture experiment in two adjacent habitats; a large plot with oilseed radish (Raphanus sativus) and a plot with rye (Se...

Computer modelling of many real life systems is always challenged with how the dynamic changes of resources and queues are handled and integrated. In this paper, we integrate the dynamic changes of resources and queues in a discrete event model using Rockwell Software Arena, one of most used software tools in modelling discrete events, as it includes and considers the resources by queuing compo...

This study presents a reduction of production disturbances of a shoemaking industry through discrete event simulation approach. The study is conducted at Peacock Shoe factory found in Addis Ababa, Ethiopia.  This factory faces line balancing problem that becomes production disturbance for its assembly lines. Detail time study is carried out for the selected shoe model using stopwatch. Assembly ...

This paper presents a model of teachers’ construction of mathematics curriculum in the classroom or their curriculum development activities. The model emerged through a qualitative study of two experienced, elementary teachers during their first year of using a commercially published, reform-oriented textbook that had been adopted by their district (Remillard 1996). The aim of the study was to ...
