Do children play fair with mother nature? Understanding children’s judgments of environmentally harmful actions

The current study asks how young children judge behaviors that harm the environment as compared to moral transgressions, social-conventional transgressions, and personal choices. This study also questions whether children are more likely to cite biocentric or homocentric reasons when justifying their judgments of environmentally harmful behaviors. To answer these questions, sixty-one 6–10 year olds were asked to judge the severity of various actions that impact the environment. For comparison, participants also judged moral transgressions, social-conventional transgressions, and personal choices. Children judged actions that harm the environment more severely than social-conventional transgressions but not as severely as moral transgressions. When justifying their judgments of these environmentally harmful behaviors, participants were more likely to reference biocentric reasons as compared to homocentric reasons. The findings suggest that children perceive harm to the environment as bad, but harm to humans as worse.     

Coordinative Development in Population,Resources and Environment—China's Central Concern in Developing Science and Technology

Abstract

Population, resources and environment constitute the basis for economic and social advances. Their coordinative development is the key factor for the continuous, stable and harmonious development of economy and society. China is a developing country which needs to mobilize the whole society to coordinate among population, resources and environment and to keep publicity and research in pace so as to deepen people's understanding and improve the methods of achieving this coordination.     

The Cultivation,Mainstreaming, and Cognitive Processing of Environmentalists Watching Television

Cultivation theory research has found a relationship between heavier viewing of television and less concern about the natural environment. The current research delves further into this issue by exploring how environmentalists’ television viewing is related to their attitudes about the environment. The findings indicate that when overall television viewing is the independent variable, there are cultivation and mainstreaming effects for environmentalists (i.e., environmentalists who were heavy viewers of television scored lower on the new environmental paradigm (NEP) scale than lighter viewing environmentalists, and were more similar to the general public in their environmental attitudes than lighter viewers). The findings also show that the cultivation effects are related to need for cognition (NFC) and attention to television (such that those with higher NFC, and those who pay more attention to television, have lower scores on the NEP scale). When non-fiction programming is the independent variable, however, heavier television viewers score higher on the NEP, and NFC and attention to television do not relate to the cultivation effect.     

Anthropocentric Distance in National Geographic's Environmental Aesthetic

Tourism is the way we understand the world: tourists travel in an increasingly mediated environment in which ubiquitous promotional material and other popular artifacts employ stunning images and romantic travel narratives to describe local environments. Tourist texts “sell” local landscapes to entice visitors, employing an environmental aesthetic that urges travel. With its mission to “explore the planet,” the National Geographic Society contributes to this tourist aesthetic. This essay examines three special issues on Africa simultaneously published by the National Geographic Society: its official journal, National Geographic, and its sister magazines, National Geographic Traveler, and National Geographic Adventure. The photographic images and travel narratives in these tourist texts produce an environmental aesthetic that positions the traveler at the center of these environments. This essay first analyzes how National Geographic constructs Africa's environmental landscapes. These magazines depict Africa as a vast desert plain, a wilderness theme park, and a part of the global scenery. The second part of the analysis examines how National Geographic locates the tourist in these environments. I discuss how National Geographic positions the tourist as protagonist, expert, and hero of Africa's environment. In the conclusions, I argue this environmental aesthetic renders Africa invisible through anthropocentric distance, and I discuss the need for more critical readings of tourist discourse.     

The Concepts of Energy,Environment, and Cost for Process Design

Abstract

The process industries (specifically, energy and chemicals) are characterized by a variety of reactors and reactions to bring about successful process operations. The design of energy-related and chemical processes and their evolution is a complex process that determines the competitiveness of these industries, as well as their environmental impact. Thus, we have developed an Enviro-Energy Concept designed to facilitate sustainable industrial development. The Complete Onion Model represents a complete methodology for chemical process design and illustrates all of the requirements to achieve the best possible design within the accepted environmental standards. Currently, NOx emissions from industrial processes continue to receive maximum attention, therefore the issue problem of NOx emissions from industrial sources such as power stations and nitric acid plants is considered. The Selective Catalytic Reduction (SCR) is one of the most promising and effective commercial technologies. It is considered the Best Available Control Technology (BACT) for NOx reduction. The solution of NOx Emissions problem is either through modifying the chemical process design and/or installing an end-of-pipe technology. The degree of integration between the process design and the installed technology plays a critical role in the capital cost evaluation. Therefore, integrating process units and then optimizing the design has a vital effect on the total cost. Both the environmental regulations and the cost evaluation are the boundary constraints of the optimum solution.
