We study the use of the generative systems known as computational ecosystems to convey artistic and narrative aims. These are virtual worlds running on computers, composed of agents that trade units of energy and emulate cycles of life and behaviors adapted from biological life forms. In this article we propose a conceptual framework in order to understand these systems, which are involved in p...

The viscoelastic properties of three commercially available resin-based composites (FiltekTM P60, FiltekTM Supreme, and FiltekTM Z250; 3M ESPE, Bracknell, UK) were measured to determine the effect of beverages on their storage moduli and damping ratios. Rectangular samples of the three hybrid composites were immersed in three beverages at 37 °C for 1, 7, 30, and 60 days. At each time interval, ...

From Illegal to Legal: Estimating Previous Illegal Experience among New Legal Immigrants to the United States This paper develops a framework for estimating previous illegal experience among annual cohorts of new legal immigrants to the United States – using public-use administrative microdata alone, survey data alone, and the two jointly – and provides estimates for the FY 1996 cohort of new i...

This chapter focuses on virtual communities of practices, and whether participation in such forums improves knowledge retrieval processes by overcoming problems of contextual gaps between the sender and the receiver of knowledge. Most multinational corporations (MNCs) have invested heavily in computer systems that help employees to easily download documents, but problems still arise when the se...

the subject under investigation has been electronic learning (e-learning) or electronic education (e-education), specifically concentrating on virtual university. virtual university has been the subject of much debate in recent years. in short, the concept of virtual university denotes a learning/educational system/environment based on internet where higher education is promoted using tools and...

As global competition drives corporations into distant, unfamiliar markets, managers are searching for ways to minimize their uncertainty. When formulating their strategies for such environments, managers frequently rely on country risk analysis. Assuming that country risk analysis is an objective, fact-finding process, many managers fail to question these risk reports. The focus of this paper ...

background : along with emersion of the internet, virtual education increasingly has been growing. many studies discussed this method and its impact on learning. present study investigated students’ attitude towards virtual education as well as its effect on learning. methods : this was a pretest-posttest quasi-experimental study. the nursing students, who had selected fluids and electrolyte di...
