Two paradigms of professional development in environmental education

Summary In environmental education in this information age, it is particularly important to adopt the approach of enquiring critically into the environmental, educational and social values informing environmental, educational and social actions when and where required, rather than to simply adopt the approach of emphasising the acquisition and retention of information of an alleged universal type — information drawn from the stockpile of objective knowledge collected by others. This paper argues that to achieve this aim, environmental education in an information age requires aparadigm shift in the areas of professional development — a shift from a paradigm of information technology to a paradigm of information critique. A perspective on the form of this paradigm shift in the particular field of professional development in environmental education is the subject of this paper.Dr Ian Robottom is Senior Lecturer in the Curriculum Studies Centre of the School of Education, at Deakin University, Australia.

UK interpretation and implementation of the EEC Shellfish directive

The EEC Shellfish Directive is a policy designed to protect and, where necessary, improve the quality of designated shellfish waters. Its implementation within the UK, however, has had no effect upon water quality for two reasons. First, the policy has important defects, having ambiguities concerning public health provisions and lacking designation criteria. Second, UK government has sought to achieve formal compliance, while at the same time ensuring that its full financial impact on public expenditure has been contained. Consequently, only those fisheries which already comply with water quality standards have been designated. Within Wales, one fishery has been designated, while other, commercially more important, but grossly contaminated shellfisheries have not.     

Safety climate

Safety climate, the objective measurement of attitudes and perceptions toward Occupational Health & Safety (OH&S) issues, has been largely ignored and measures such as lost time and frequency rate have been used to determine the efficacy of OH&S programs. Yet, it is clear that measuring the precursors of accidents identified in a safety climate analysis provides a powerful proactive management tool. This paper reports on safety climate factors found in clerical and service organizations in Australia. Concurrent validity studies are reported. In contradistinction to published studies, it is argued that safety climate factors are not stable across organizations. The significance of this for planning and assessing the efficacy of OH&S programs is discussed. It is concluded that although safety climate factors are not stable, the safety climate factor pattern identified in organizations provides a powerful management tool for designing OH&S programs.     

Urbanization's impact on timber harvesting in the south central United States

The impact of urbanization on timber harvesting in the south central United States was investigated. Geo-referenced Census and Forest Inventory Analysis (FIA) data were combined using a geographic information system (GIS) in order to examine the effects of various demographic and biophysical forest inventory characteristics on timber harvesting. These effects were estimated for intermediate and final harvests using a multinomial logit model. The probability for both types of harvests decreased with increasing population density, decreasing forest size, and decreasing distance to urban areas; however, the reduction in intermediate harvests was greater for each variable. Harvesting rates decreased by as much as 19% as population densities increased or distance to urban areas decreased. The results indicated that active forest management is curtailed far beyond the urban boundary. In order to model the impact of urbanization adequately, timber supply projections must also account for its impact on harvesting frequencies in surrounding areas.     

In situ agrobiodiversity conservation: Examples from Nepal,Turkey and Switzerland in the first decade of the convention on Biological Diversity

Applications of in situ agrobiodiversity conservation practices within agricultural production systems have the potential to reduce the risks of agricultural modernisation and enhance sustainable development. The aims and approaches for in situ conservation differ according to the requirements of communities and nations. Approaches to in situ conservation in the decade after the Convention of Biological Diversity are reviewed within the contexts of marginal agricultural systems in Nepal, Turkey and Switzerland. Numerous approaches are currently utilised, including: the informal de facto retention of agrobiodiversity; the provision of state assistance; the marketing of agrobiodiversity products; the use of technological innovations to develop local diversity; the establishment of conservation reserves; community assistance programmes and the raising of awareness of the issue amongst all sectors of societies. Emerging complementary in situ approaches applicable in the rural margins suggest a framework for effectively conserving agrobiodiversity by working with local people.     

Dynamic workplans and field analytics: Metals assessment by inductively coupled plasma/optical emission spectroscopy

Hazardous waste site investigations were carried out at the Marine Corps Air Station (MCAS) in Yuma, Arizona and at Hanscom Air Force Base (HAFB) in Bedford, Massachusetts. The purpose of the first was to determine the location and extent of metals contamination throughout the base. The objective of the second was to evaluate the risk of metals contamination to groundwater from soil at three locations within the airfield. Dynamic workplans were developed and an adaptive sampling and analysis plan carried out with the data produced in the field used to support the goals of each project. An inductively coupled plasma/optical emission spectrometer (ICP/OES) was modified for field operation. A more efficient microwave digestion method and pressurized Teflon filtration system were developed for the HAFB project. Results were comparable to standard Environmental Protection Agency (EPA) methods, which must rely on two digestion procedures to recover EPA-targeted metals within the prescribed recovery range. The MCAS investigation, conducted over a five-month period, advanced the Navy's efforts from 30 months behind schedule to 18 months ahead of schedule, while the data generated at HAFB showed no risk to groundwater from metals.
