why, when and how are some people more capable of recognizing opportunities while others lack such ability? this is a key question to pose in the field of entrepreneurship and opportunity recognition. the answer to this question can open up a new window before researchers. the aim of this research is to examine the factors that are effective in determining opportunities among entrepreneurs. to ...

Business process models are a suitable means to describe the temporal and logical order of tasks for achieving a given goal. Therefore they become crucial in the coordination of intervention actions to efficiently recover from a disaster or tragic event. Past experience is vital in handling these scenarios, but every new emergency would almost always present peculiar characteristics. So althoug...

We show that drought-induced changes in the intensity of riots lead to moves towards democracy in sub-Saharan Africa, and that these changes are often a result of concessions made as a result of the riots. This provides evidence that low-intensity conflict can have a substantial short-run impact on democratic change, and supports the “window of opportunity” hypothesis: droughts lead to an incre...

This paper addresses the problem of guaranteed delivery of messages with hard deadlines in a DQDB network. We present a cyclic reservation scheme capable of allocating bandwidth with any arbitrary granular-ity and provide deterministic delay guarantees. We propose two implementations of the allocation scheme within the framework of DQDB medium access control protocol. The proposed implementatio...

Health care processes are nowadays heavily dependent on Information Technology (IT). On the other side, assessing a higher quality of health care to patients has become increasingly important. Effective health care processes are thereby heavily dependent on a comprehensive IT-support. Therefore, a thorough understanding about both the hospital IT-systems and clinical pathways is required, to id...

Sensor networks that can support time-critical operations pose challenging problems for tracking events of interest. We propose an architecture for a sensor network that autonomously adapts in real-time to data fusion requirements so as not to miss events of interest and provides accurate real-time mobile target tracking. In the proposed architecture, the sensed data is processed in an abstract...
