For the resulting systems of ordinary differential equations dissipativeness conditions, the invariance of nonnegative cone in the phase space, and the form of the Jacobi matrix in equilibrium are established. Examples are presented of numerical experiments with models of a particular wetland ecosystem....

In June 2007 the American Journal of Community Psychology published a special issue focused on theories, methods and interventions for systems change which included calls from the editors and authors for theoretical advancement in this field. We propose a conceptual model of systems change that integra...

Co-culture systems produce more food per land unit — offering a sustainable solution to food security. The first step may lie in optimizing for diverse species interaction networks, much like the way engineers design manufacturing systems for optimal productivity. ...
This study proposes the Ecological Systems Model of Creativity Development, which emphasizes the dynamic relationships among 4 ecological systems, each individually representing personal characteristics, the family and school experiences, organizational environment, and the social milieu. The findings here confi...
model, linking sea level rise to changes in the hydrologic cycle, and ultimately producing significant impacts on both social and ecological systems (arrow 2). In this paper, we explore the linkages and feedbacks in rural, coastal, social-ecological systems, drawing specific examples from the APP...
Ecological systems theory: This theory looks at a child's development within the context of the system of relationships that form his or her environment. Bronfenbrenner's theory defines complex "layers" of environment, each having an effect on a child's development. This theory has recently been...
especially in systems with a high level of variability and uncertainty, may induce permanent ecosystem changes. Therefore, to effectively manage groundwater in these systems, there must be robust local groundwater-level data to evaluate impacts, set targets and adjust thresholds as needed. Currently,...
