The complexity of energy systems operation and the necessity to design secure and reliable systems, compatible with greenhouse gas (GHG) mitigation goals, have justified the development of energy models. They are capable of representing detailed energy systems (technical and economic characteristics) and the interconnections between supply and consumer sectors, assessing energy consumption and ...

The growing use of information technology and the Internet has led to the emergence of professional virtual communities (PVCs). Why are PVC members willing to spend time and energy to provide valuable knowledge to others? This study extended Icek Ajzen’s(1991) theory of planned behavior (TPB) to analyze what determines PVC members’ willingness to share knowledge. Empirical data were collected f...

In this paper we examine classical and fundamental processes of business planning and marketing. As a result we define a five-phase process model for planning and marketing and we examine the relationship of planning and marketing to both the acquisition cycle and the research, development, test, and evaluation cycle. We construct a product life cycle—an abstraction that is a familiar part of m...

During the month-long METCRAX field campaign in northern Arizona near Winslow in October 2006, observed wind profiles uncovered a frequent presence of a nearsurface wind maximum on nights with relatively quiescent synoptic conditions. The development of this flow usually began shortly after sunset with a shift from disorganized wind directions accompanying weak winds in late afternoon to a more...

By constructing a risk model for estimating the risks involved in industrial safety, and by investigating and analyzing the obtained results, areas that should be considered as priorities in risk reduction are clarified. In the present study, the risks involved in industrial safety are classified into five categories: fire and/or explosion, strong winds, flooding, lightning, and earthquake. An ...

The management of intraand inter-organizational business processes is a significant issue that influences company’s success. Many business processes are not fully automated and require human interaction. Therefore, responsibilities for tasks have to be assigned by workflow management systems. Common resource models allow the selection of resources according to their roles, thus neglecting compe...

During the twentieth century, the natural landscape of the Florida peninsula was transformed extensively by agriculture, urbanization, and the diversion of surface water features. The purpose of this paper is to present a numerical modeling study in which the possible impacts of this transformation on the warm season climate of the region were investigated. For three separate July–August period...

Introduction If 'sustainability' is an icon of environmentalists in southern Africa, so too is 'integration' for scientists drawn into this arena. Scientists seem to be less capable than their compatriots, however, at substantiating their ideals. Popular environmentalism thrives on various forms of civic pressure on government and industry to 'clean up their acts'. Conservation agencies can sho...

This paper examines the extent to which there are differential incentives that motivate the adoption of environmental management practices (EMPs) and pollution prevention (P2) methods. We analyze the role of internal drivers such as managerial attitudes towards the environment and external pressures using both observed characteristics of facilities and perceived pressures. We estimate a structu...

Contemporary CEMIS do not cope with requirements from the sustainability discussion. At the time of reporting environmental performance, it is too late to set the right course. Without an early identification of cause and effect to anticipate environmental impacts of decisions for timely intervention, potentials for acting precautious remain unemployed. A resource-friendly design of processes a...
