We use new survey data from 1,203 households in rural Eastern India to estimate cross-sectional models of overall energy use and embedded emissions. Findings indicate that the primary driver of household energy use is household size and affluence. This is unsurprising and consistent with findings from the engineering literature on energy demand.…

Conceptions of ecological processes such as the flow of energy and cycling of matter in an ecosystem are increasingly important understandings in a rapidly changing world. This study utilizes a p-prims, or knowledge in pieces, lens to examine understandings and disconnections in students' conceptualizations of energy flow and matter cycling…

Guided by the Next Generation Science Standards and elements of problem-based learning, four human-environment systems simulations are described in brief--carbon, energy, water, and watershed--and a fifth simulation on nitrogen is described in more depth. These science, technology, engineering, and math (STEM) education simulations illustrate…

With the Arab oil embargo of 1973, the United States became aware of its dependence on foreign fuel to maintain its productive capacity, employment base, political autonomy, strategic security, and living standard. An engineering Task Force on Energy was appointed to provide an informed assessment of the realistic strategies that could be…

Identified some of the misconceptions held by secondary science students (N=232) related to selected ecological concepts and generalizations. Lists the alternative conceptions expressed by these students on food chains and energy flows and pyramids. Offers perspectives on dealing with the sources of the misconceptions. (ML)

Eleven articles comprise this document which presents commentaries on nutrition, population, and environmental education. The articles deal specifically with the crises of a rapidly growing world population, a worsening world food situation, and an energy crisis. A number of specific recommendations, both national and international, are offered to…

The technique originating from the study of ecological systems for the examination of dynamic educational systems over time is utilized. The technique is based on the theory of energy exchanges in interactions between variables. Using this technique, interactions among variables can be specified and simulated over time using an analog computer.…

Compares differences in resource exploitation and energy development in Louisiana and western mineral-producing states. Identifies socioeconomic impacts of Louisiana's offshore drilling and western coal, oil, and natural gas mining, noting the boom and bust cycles and "hyperurbanization" that attends both. Stresses the necessity of…
