The GERRI project materializes the Grenelle Environnement’s goals, of which the energy management of a territory is a facet. The aim is to forecast future energy production and consumption, bearing in mind economic and ecological indicators, and using a large number of interactions schemes between the involved parties. The originality of this paper is to present a new approach using the multi-a...
A few recent studies have found evidence showing that social anxiety is associated with diminished positive affect and elevated anger. However, prior work has relied on trait self-report measures of global positive mood or anger. In this preliminary study, we examined how trait social anxiety relates to moment-to-moment positive and angry emotional states as people navigate through their natura...
Through the Blueprints for Violence Prevention Initiative, OJJDP provides information to communities on a broad array of violence prevention and intervention programs that have been proven to be effective. This Bulletin describes the demanding criteria established by the Center for the Study and Prevention of Violence to designate model Blueprints programs and the activities of the 11 programs ...
Modeling social-ecological interactions between humans and ecosystems to analyze their implications for sustainable management of social-ecological systems (SES) has multiple challenges. When integrating social and ecological dynamics, which are often studied separately, one has to deal with different modeling paradigms, levels of analysis, temporal and spatial scales, and data availabilities i...
Changes in ecological vulnerability were analyzed for Northern Shaanxi, China using a geographic information system (GIS). An evaluation model was developed using a spatial principal component analysis (SPCA) model containing land use, soil erosion, topography, climate, vegetation and social economy variables. Using this model, an ecological vulnerability index was computed for the research reg...
Four decades ago, Leigh Van Valen presented the Red Queen's hypothesis to account for evolution of species within a multispecies ecological community [Van Valen L (1973) Evol Theory 1(1):1-30]. The overall conclusion of Van Valen's analysis was that evolution would continue even in the absence of abiotic perturbations. Stenseth and Maynard Smith presented in 1984 [Stenseth NC, Maynard Smith J (...
ABSTXKT. In situations where the only reliable data source is electoral data at the aggregate level for a geographic unit such as voting precincts, social scientists have sought to use ecological regression techniques to recreate the voting behavior of particular groups without committing the ecological fallacy of the sort warned of by Robinson (1950). Until quite recently, the most common use ...
background determinants of health or health production function in health economics literature constitute noticeable issues in health promotion. this study aimed at estimating a health production function for east mediterranean region (emr) based on the grossman theoretical model. methods this ecological study was performed using the econometric methods. the panel data model was used in order...
This paper introduces a view on planning that is based on interpreting objects not by their identity but by their functionality. Ecological psychologist J.J. Gibson’s concept of affordances provides the underlying theory for developing a system that does not distinguish between objects of functional equivalence. It will be argued that the plans resulting from this approach are both less complex...
The goal of this paper is to propose a performance assessment for normally closed-loop type distribution power systems. Pilot relaying systems have been successfully applied to the protection scheme for normally closed-loop distribution systems in the Taiwan Power Company (Taipower). This paper demonstrates that the proposed protection scheme is extremely well designed, such that both the numbe...
