This article describes an approach to substantiate the premise that good sanitation has economic benefits. It details the results of a research study conducted to measure the cost effectiveness of good sanitation in a retail food store meat department and found a 5.3% decrease in product reprocessing loss.

In the research of environmental impact assessment (EIA), the problem of weight distribution for a set of parameters has not yet been properly solved. Presents an approach of objective weighting by using a procedure of Pij principal component-factor analysis (Pij PCFA), which suits specifically those parameters measured directly by physical…

Discusses the history and current developments of the Biosphere 2 Project, a prototype for enclosed self-sustaining structures for space colonization built in the Arizona Desert. Biosphere 2 was created to educate and provide solutions to environmental problems and revenue from research. (MCO)

In spite of rapid progress achieved in the methodological research underlying environmental impact assessment (EIA), the problem of weighting various parameters has not yet been solved. This paper presents a new approach, fuzzy clustering analysis, which is illustrated with an EIA case study on Baoshan-Wusong District in Shanghai, China. (Author)

Discusses the objectives of conserving nature, appropriate strategies to reach those objectives, the present situation of formal conservation in South Africa, and the role of research in formulating sound conceptual models of ecosystem structure and function. (MDH)

Concentrations of chemical substances and microorganisms are often averaged using geometric means. Argues that the arithmetic mean is a better choice for summarizing data because arithmetic means are unbiased, easier to calculate and understand, scientifically more meaningful, and more protective of public health. Results of a simulation study…

Green chemistry is the awareness of the damaging environmental effects due to chemical research and inventions. There is emphasis on a need to include green chemistry in synthesis with atom economy in organic chemistry curriculum to ensure an environmentally conscious future generation of chemists, policy makers, health professionals and business…

For a generation or more, environmental education discourses have been constructed around persistent Cartesian dualisms of modernist thought that divide an "othered" category of being from that of a constituted homogeneous human identity. During the same period, both feminist and poststructuralist theorizing has acted to destabilize the…

Monte Carlo computational experiments reveal that the ability to discriminate between first- and second-order kinetics from least-squares analysis of time-dependent concentration data is better than implied in earlier discussions of the problem. The problem is rendered as simple as possible by assuming that the order must be either 1 or 2 and that…

The human dimensions of greenhouse gas emissions and global warming attract considerable attention in macrosociology. However, cross-national analyses generally neglect greenhouse gases other than carbon dioxide. The current study addresses this paucity through the testing of theoretically derived models for the social structural causes of the…

In this article, the author discusses the implications of articles by Louise Chawla (1998) and Karen Malone (1999a) for "doing research." One of the most interesting implications of these two papers for environmental education research is the issues they raise about the challenges for environmental education researchers and education researchers…

This paper reports on a study conducted among Greek kindergarten teachers aiming to explore their conceptual frameworks on a major environmental issue of our times: the ozone layer depletion. The choice of this particular issue was premised on its novelty, complexity and abstractness which present teachers with difficulties in its teaching. A free…

The environmental and interdisciplinary nature of environmental education presents extraordinary challenges to individuals' abilities as a field to clearly conceptualize, theorize and communicate findings about what they have learned about practice, research and theory in environmental learning (Disinger, 2001). Unfortunately, these factors also…

The Psychological well being Inventory (PWBI) is a multidimensional instrument that has enjoyed widespread use in a variety of research initiatives, from small-scale studies to national surveys. Recent empirical investigation of the measure has raised questions about its validity. This study examines the factorial validity of the Environmental…

Modern Western philosophy and the philosophy of Alfred North Whitehead reveal why geography has not been (but could be) at the forefront of the environmental movement. The dualism between man and nature of western thought has led to misuse of the environment; whereas Whitehead's philosophy recognizes harmony between man and nature. (JR)
