Vegetarianism,morality, and science revisited

Professor Kathryn George's Use and Abuse Revisited does not contain an accurate assessment of my On Vegetarianism, Morality, and Science: A Counter Reply. I show that she has misrepresented my moral and empirical argumentation.     

Carrying capacity as "Informed Judgment": the values of science and the science of values

Contemporary park and wilderness carrying capacity frameworks rely on formulation of standards of quality, which are defined as minimum acceptable resource and social conditions. Formulation of standards of quality involves elements of both science and values, and both of these elements must be integrated into informed judgments on the part of park and wilderness managers. That is, managers must ultimately make value-based judgments about the maximum acceptable level of visitor-caused impacts to the resource base and the quality of the visitor experience. However, such judgments should be as informed as possible by scientific data on the relationships between visitor use and resulting impacts and the degree to which park and wilderness visitors and other interest groups judge such impacts to be acceptable. Such information represents the “values of science” to managing carrying capacity in parks and wilderness. A growing body of literature has begun to address the corresponding “science of values,” and how this type of information might be integrated in park and wilderness management. Visitor-based research has employed normative theory and techniques to explore the acceptability of a range of resource and social impacts related to visitor use, and findings from these studies are being integrated into a body of knowledge and applied in management decision-making. Conceptual and methodological extensions of the normative approach are currently being explored in a variety of park and wilderness contexts, and new theoretical and empirical approaches are being adapted to address trade-offs inherent in carrying capacity. In these ways, the science of values is progressing to meet the opportunities and challenges of the values of science to park and wilderness management. The concept of carrying capacity, along with the theoretical and methodological approaches described in this paper, can be extended to a large number of natural resource and environmental issues.     

Advances in materials science and changes in the metal industry

High temperature superconductivity is representative of the advances being made in the science of materials. Both the theoretical and practical understanding of materials is making great progress. The advances are changing the world in which metals producers operate. One of the major changes is that the material-use decision is becoming more complex. The new materials have an advantage against the older materials in that they dominate the general discussions, relegating metals to a 'has-been' role. Unless the metals industries become more adept at maintaining the knowledge that metals are adaptable and suitable for most uses, metals will suffer greater than necessary losses in market share to new materials.     

Panarchy use in environmental science for risk and resilience planning

Environmental sciences have an important role in informing sustainable management of built environments by providing insights about the drivers and potentially negative impacts of global environmental change. Here, we discuss panarchy theory, a multi-scale hierarchical concept that accounts for the dynamism of complex socio-ecological systems, especially for those systems with strong cross-scale feedbacks. The idea of panarchy underlies much of system resilience, focusing on how systems respond to known and unknown threats. Panarchy theory can provide a framework for qualitative and quantitative research and application in the environmental sciences, which can in turn inform the ongoing efforts in socio-technical resilience thinking and adaptive and transformative approaches to management.     

Employability of environmental science graduates in Australia

Since the 1970s, there has been a global proliferation of environmental courses. The types of courses are described, as are the structures, philosophies and objectives of courses which have stood the test of time. Employment of environmental graduates is discussed. The degree in Australian Environmental Studies (AES) from Griffith University is described and discussed with reference to pitfalls described in the literature. In Australia, there has been an increased demand for graduates in the environmental area. The trend in employers has been widening the field of potential recruits by keeping the degree specification broad and using the duty statements in the advertisements to specify the environmental skills and knowledge required. The number of graduates from AES has increased steadily since the course was established, and despite global and national trends of proliferation of environmental courses and graduates, survey results indicated that graduates from AES are professionally employed in a wide range of employment sectors, with female and male graduates being equally successful in obtaining employment.     

State-of-the-art science and environmental assessments: the case of acid deposition

Scientific quality in a technical policy document is defined in terms of the proportion of contemporary scientific principles on a subject that the document competently discusses. As a case study of the scientific quality of such documents, this articles examines the treatment of acid deposition effects in 126 environmental impact statements on fossil-fuel power plants. On average, the relevant environmental statements cover only a quarter of the eligible scientific principles. Bureaucratic and political factors influence the quality of discussion of acid deposition more than do strictly objective or scientific factors. In particular, public participation and interagency review processes foster relatively thorough consideration of scientific information in environmental impact statements.     

Soil quality in New Zealand: policy and the science response

Soil depletion and degradation have been increasingly recognized as important environmental issues in many parts of the world. Over the last decade a number of political and legislative measures have been introduced to encourage and enforce sustainable soil management in New Zealand. Application of the new legislation has highlighted gaps in our knowledge of soil quality and a lack of scientific methods to assess and monitor soil quality. This paper describes the legislative measures and outlines the sdentific response to the needs of regulatory agencies responsible for maintaining environmental quality. The research recommended a set of indicators to assess soil quality. Each soil quality attribute has an associated "target range" defining the acceptable value for the attribute. The paper also discusses the communication of results to end-users, including the development of a computerized assessment tool. The legislative measures and scientific response have fostered a closer relationship between the policy and science communities, leading to more well-focused research, but greater collaboration is still required.     

The conceptual bases of chemistry and the development of integrated science

Summary A paradigmatic model of the evolution of scientific thought encourages awareness of the provisional nature of present scientific explanations, sensitizing us to aspects of observed reality which they are unable to adequately explain. The self-organizing capabilities of open systems, exemplified by the clock-reactions investigated by Prigogine, not only demonstrate the inadequacies of the present probabilistic scientific interpretations but also point towards a more adequate model of scientific explanation which would place man at the centre of scientific development and encourage the integration of science.Dr Paolo Manzelli, as the senior author of this paper, is Professor in the Department of Chemistry at the University of Florence.

An overview of Turkish research and education in environmental social science

The article presents an overview of environmental psychology research and education in Turkey within the general context of environmental social science. Brief accounts of the context, issues, ideas and methods of research are provided. Reference is made to relevant key research centres and education programmes. The findings of a survey that aimed to reveal the potential and orientations of such research in Turkey are used to support the arguments.The recent environmental social research reviewed indicates conflicting attitudes to the environment as a consequence of the joint existence of Eastern and Western life styles; contradictory conceptualizations of concepts such as crowding, complexity and privacy in comparison to the findings of Western studies, lack of specialization in use of space in the Western sense and a highly male and adult centred place use.A call is made for international collaboration with the developing and industrialized nations for joint work on theoretical and empirical issues in the field of environmental social sciences.     

Will science parks generate the fifth wave?

The paper examines characteristics of science parks in the face of employment decline, raising doubts about the scale of their success. The paper re‐examines previous research on the existence and causes of long waves of economic growth and decline and concludes that if these are not generated by innovations in production, then it should not be surprising that science parks have not lived up to expectations.     

Identifying hydrologically sensitive areas: bridging the gap between science and application

Researchers have noted that current water quality protection strategies, like nutrient management plans, lack a sound hydrological underpinning for pollutant transport processes. This is especially true for areas like the northeastern U.S. where copious research has shown that variable source area hydrology largely governs runoff generation. The goal of this study was to develop a scientifically justified method to identify the locations that generate overland flow. Furthermore, this methodology must be computationally simple enough that it can be utilized or incorporated into nutrient management plans and other established water quality tools. We specifically tested the reliability of the 'distance from a stream,'D(s), and the 'topographic index,'lambda, to predict areas with a high propensity for generating overland flow, i.e. hydrologically sensitive areas (HSA). HSAs were defined by their probability of generating runoff, P(sat), based on 30 year simulations using a physically based hydrological model. Using GIS, each location's P(sat) was correlated with D(s) and lambda. We used three Delaware Co., NY watersheds in the New York City watershed system with areas varying in size from 1.6 to 37 km2 and with forested and agricultural land uses. The topographic index gave stronger, more regionally consistent correlations with P(sat) than did D(s). Equations correlating lambda and P(sat) for each month are presented and can be used to estimate hydrological sensitivity in the region surrounding our study watersheds, i.e. in Delaware Co. This work is currently being incorporated into an Internet Mapping System to facilitate user-friendly, on-line identification of HSAs.
