Computational Logic: Logic Programming and Beyond

by Robert Kowalski

2002 · Springer Science & Business Media

The book contains the proceedings of the 12th European Testis Workshop and gives an excellent overview of the state of the art in testicular research. The chapters are written by leading scientists in the field of male reproduction, who were selceted on the basis of their specific area of research. The book covers all important aspects of testicular functioning, for example, Sertoli and Leydig cell functioning, spermatogonial development and transplantation, meiosis and spermiogenesis. Even for those investigators who were not present at the workshop, this volume provides a clear impression of the topics discussed during that meeting.

Microbial and Enzymatic Degradation of Wood and Wood Components

by Karl-Erik L. Eriksson, Robert A. Blanchette, Paul Ander

2012 · Springer Science & Business Media

The oil crisis during the 1970s turned interest towards the utilization of renewable resources and towards lignocellulosics in particular. The 1970s were also the cradle period of biotechnology, and the years when biotechnical utilization of lignocellulosic waste from agriculture and forestry gained priori ty. This was a logical conclusion since one of nature's most important biologi cal reactions is the conversion of wood and other lignocellulosic materials to carbon dioxide, water and humic substances. However, while biotechnology in other areas like medicine and pharmacology concerned production of expen sive products on a small scale, biotechnical utilization and conversion of ligno cellulosics meant production of inexpensive products on a large scale. Biotechnical utilization of lignocellulosic materials is therefore a very difficult task, and the commercial utilization of this technology has not progressed as rapidly as one would have desired. One reason for this was the lack of basic knowledge of enzyme mechanisms involved in the degradation and conversion of wood, other lignocellulosics and their individual components. There are also risks associated with initiating a technical development before a stable platform of knowledge is available. Several of the projects started with en thusiasm have therefore suffered some loss of interest. Also contributing to this failing interest is the fact that the oil crisis at the time was not a real one. At present, nobody predicts a rapid exhaustion of the oil resources and fuel production from lignocellulosics is no longer a high priority.

Organizational Influence Processes

by Lyman W. Porter, Harold L. Angle, Robert W. Allen

2003 · M.E. Sharpe

With more than two-thirds fresh material, this new updated edition of Organizational Influence Processes provides an overview of the most important scholarly work on topics related to the exercise of influence by individuals and groups within organizations. In selecting articles for inclusion the editors were guided by the conviction that the most useful and interesting way to view organizational influence is to take a directional approach - that is, to consider the process from the perspective of downward, lateral, and upward influence. They have organized the readings around this framework, preceded by an introductory group of articles dealing more generally with the nature of influence processes and power. The book includes both classic readings and the latest cutting edge research from some of the most respected experts writing in the field. It will be equally useful for any upper level undergraduate or graduate course concerned with organizational behavior, group behavior, leadership or power and politics.

Whole Body Interaction with Public Displays

by Robert Walter

2017 · Springer

This book develops valuable new approaches to digital out-of-home media and digital signage in urban environments. It offers solutions for communicating interactive features of digital signage to passers-by. Digital out-of-home media and digital signage screens are becoming increasingly interactive thanks to touch input technology and gesture recognition. To optimize their conversion rate, interactive public displays must 1) attract attention, 2) communicate to passers-by that they are interactive, 3) explain the interaction, and 4) provide a motivation for passers-by to interact. This book highlights solutions to problems 2 and 3 above. The focus is on whole-body interaction, where the positions and orientations of users and their individual body parts are captured by specialized sensors (e.g., depth cameras). The book presents revealing findings from a field study on communicating interactivity, a laboratory on analysing visual attention, a field study on mid-air gestures, and a field study on using mid-air gestures to select items on interactive public displays.
