Following the works of Shane and Venkataraman (2000), the concept of opportunity has become the focus of a growing body of research at the interface of management, strategy and entrepreneurship (e.g., Eckhardt & Shane, 2003; Gartner et al., 2003). Interestingly, there is also a long tradition of research in managerial cognition that looks at the relationship between managers categorization of e...

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...

Relational Over the last two decades, the advances in computer vision and pattern recognition power have opened the door to new opportunity of automatic facial expression recognition system[1]. This paper use Canny edge detection method for facial expression recognition. Image color space transformation in the first place and then to identify and locate human face .Next pick up the edge of eyes...

The present study examined human-computer interactions in which the operator has to detect errors made by software designed to automatically recognize technical documents. The goal was to assess the effect of user-initiated interruptions of the recognition process to correct these errors. Participants were asked to check the interpretations, either with or without the possibility of interruptin...

In the present work we discuss the results, which our speaker verification system, WCL-1, obtained in the 2003 NFI/TNO Forensic Speaker Recognition Evaluation. These results, together with the ones obtained in the 2003 NIST Speaker Recognition Evaluation, give opportunity for in depth analysis of the various aspects of real-world application of the speaker recognition technology. Based on the d...
