A proposed concept for a crustal dynamics information management network

The findings of a requirements and feasibility analysis of the present and potential producers, users, and repositories of space-derived geodetic information are summarized. A proposed concept is presented for a crustal dynamics information management network that would apply state of the art concepts of information management technology to meet the expanding needs of the producers, users, and archivists of this geodetic information

Building Teams from a Distance

[Excerpt] Virtual teams are comprised of individuals that are separated geographically or organizationally and that rely primarily on technology to complete tasks (Powell, Piccoli & Ives, 2004). This work arrangement has been found to be advantageous for many firms because it reduces the costs and time associated with employee travel. It also permits organizations to attract and retain top talent because workplace flexibility is increasingly seen as a crucial aspect of job satisfaction for many employees (Bergiel, Bergiel & Balsmeier, 2008). Virtual teams are also valuable to many businesses because team members commonly focus their interests on tasks instead of shared social or cultural environments, which often impact the dynamic within conventional teams (Hamilton & Scandura, 2003). This fosters a working environment that encourages innovation and decreases discrimination by hierarchy, employee impairments, race or age because productivity is more important than other characteristics (Bergiel et al., 2008). While virtual teams have many advantages, they frequently struggle to establish a strong sense of trust between individuals, frequent team member intercommunication, and effective leadership; all of which are necessary for team success

Three Minimal Market Institutions with Human and Algorithmic Agents: Theory and Experimental Evidence

We define and examine three minimal market games (sell-all, buy-sell, and double auction) in the laboratory relative to the predictions of theory. These closed exchange economies have some cash to facilitate transactions, and include feedback. The experiment reveals that (1) the competitive general equilibrium (CGE) and non-cooperative (NCE) models are reasonable anchors to locate most but not all the observed outcomes of the three market mechanisms; (2) outcomes tend to get closer to CGE predictions as the number of players increases; (3) prices and allocations in double auctions deviate persistently from CGE predictions; (4) the outcome paths across the three market mechanisms differ significantly and persistently; (5) importance of market structures for outcomes is reinforced by algorithmic trader simulations; and (6) none of the three markets dominates the others across six measures of performance. Inclusion of some mechanism differences into theory may enhance our understanding of important aspects of markets.Strategic market games, Laboratory experiments, Minimally intelligent agents, Adaptive learning agents, General equilibrium

The Living World in the curriculum: ecology, an essential part of biology learning

Argues that biology should be learnt in the living world not in the classroom. Field ecological education is essential. Ecology is ideal candidate for implementing proposed transformations in science curricula. Ecology education is the missing link in educational reform . Crucial in developing biological literacy for citizen
