The misuse of pesticide and fertilizer take a great pollution to the agricultural environment, which seriously affects the quality and safety of agricultural products. The government put forward a series of policies of subsidy to lead the farmers to proper pesticide application and scientific farming. But the effect doesn’t turn out as it wished to be because of the backward implementation meth...

Mobile learning is a powerful addition to the toolset offered by e-Learning solutions. It can extend current e-Learning benefits to provide support and training everywhere, anytime and to anyone registered to have access and with affordable costs. Mobile devices with substantial computational, networking and storage capabilities are ubiquitous today. However, attempts to employ them in training...

This paper describes a general framework for implementing dynamic routing and operational integrity control mechanisms in a Workflow Management System (WMS). The framework consists of three techniques: workfiow control matrices, sequence constraints, and event-based constraints. These techniques are described and illustrated by means of example applications. We show how these techniques can exp...

One crucial function of a workflow management system (WFMS) is to assign tasks to users who are eligible to carry them out. Except in simple workflow scenarios, roles such as secretary and manager are not a sufficient basis for determining eligibility. Additionally, WFMSs are deployed not only in group settings by small companies but also worldwide by large enterprises. Since local laws and bus...

Building a workflow management system (WFMS) is a large project. However, with the development of grid technology, it becomes easily to do that. In Open Grid Service Architecture (OGSA), everything is a service. Thus, a workflow management system can be easily built upon a set of services. Some workflow management services and important components are proposed in this paper. And the definition ...

Managing information and content on an enterprise-wide scale is challenging. Enterprise content management (ECM) can be considered as an integrated approach to information management. While this concept received much attention from practitioners, ECM research is still an emerging field of IS research. Most authors that deal with ECM claim that there is little scholarly literature available. Aft...

Short-term forecasting of wind power for about 48 hours in advance is an established technique by now. Any utility getting over a few percent wind power penetration is buying a system or a service on the market. However, once the system is installed and running day-to-day in the control room or on the trading floor, what is the best way to use the predictions? Which pitfalls are there to be awa...

Web resources in Latin American higher education institutions have been reported to show a much stronger emphasis on Information than on Communication. A Course Management System (CMS), according to Social Constructivism framework, is an opportunity for fostering learning through interaction in a virtual environment for learning; hence, stimulating the use of a CMS for communication purposes se...

Content delivery is a growing enterprise in the Internet. Critical to the management of content delivery systems is understanding customer behavior, its impact on the consumption of system resources and how together, these affect revenue. We believe that price dictates overall customer behavior and that understanding the relationship between price and customer behavior is the key to effective s...

Green information systems (Green IS) are innovative tools that can assist in achieving environmental sustainability. We investigate the manner in which institutional arrangements are brought about during the development of the Vessel Management System (VMS), a Green IS that was developed by a South Australian regulator and used for monitoring compliance with environmental protection legislation...
