Trevor Harvey 《The Environmentalist》1984,4(4):265-279
Summary Here, the author examines the management implications of a previously developed model of environmental control. A short account
of the model is given, and its implications for an integrated environmental strategy are discussed. The need for a UK, national
centre for environmental management, research, education and training is identified.
An analytical system for investigating monitoring effort derived from the model is illustrated in use, by reference to the
UK Monitoring Networks for Smoke and Sulphur Dioxide. The use of the model in providing the underlying theory for a systems
approach to environmental management is demonstrated.
The paper concludes by examining the implications of the model for education and training with special reference to technologists
and professionals. Appropriate types of environmental education for such groups are considered. A curriculum generator is
presented.
Trevor Harvey trained as a microbiologist and subsequently specialised in pollution control. He was course organiser of “Environmental
Pollution, Monitoring and Control”, an international course which was sponsored by Unesco, UNEP and WHO. This has become a
prototype for training programmes in many countries. 相似文献

The Development and Implementation of Indicators of Ecosystem Health in the Great Lakes Basin 总被引:2,自引:0,他引:2
Shear H Stadler-Salt N Bertram P Horvatin P 《Environmental monitoring and assessment》2003,88(1-3):119-151
This paper describes a process for the selection of a suite of ecosystem health indicators for the Great Lakes, as called for in the Great Lakes Water Quality Agreement. The paper also presents some preliminary data on status and trends in ecosystem components based on those indicators. The indicator selection process was carried out by over 150 scientists and managers from both Canada and the USA, and involved the presentation of the proposed indicators at the State of the Lakes Ecosystem Conferences (SOLECs). An open period for comment followed the conferences where input from scientists involved in Great Lakes programs was received. The suite of indicators will, over time, present information in an understandable format that will allow for more informed management decisions. 相似文献

Psychological entitlement refers to the phenomenon in which individuals consistently believe that they deserve preferential rewards and treatment, often with little consideration of actual qualities or performance levels. This study examines the influence of psychological entitlement on workplace outcomes, using attribution theory to explain its effects. Results suggested that entitlement perceptions are positively associated with self‐serving attribution styles and that diminished need for cognition mediates this relationship. Self‐serving attribution styles, in turn, were associated with reduced job satisfaction and increased levels of conflict with supervisors. A direct positive relationship between psychological entitlement and turnover intent was also observed. Overall, results suggest that an attributional perspective is useful in explaining and understanding the influence of entitlement perceptions on workplace outcomes.

Exposure to perchlorate is widespread in the United States and many studies have attempted to character the perchlorate exposure by estimating the average daily intakes of perchlorate. These approaches provided population-based estimates, but did not provide individual-level exposure estimates. Until recently, exposure activity database such as CSFII, TDS and NHANES become available and provide opportunities to evaluate the individual-level exposure to chemical using exposure surveillance dataset. In this study, we use perchlorate as an example to investigate the usefulness of urinary biomarker data for predicting exposures at the individual level. Specifically, two analyses were conducted: (1) using data from a controlled human study to examine the ability of a physiologically based pharmacokinetic (PBPK) model to predict perchlorate concentrations in single-spot and cumulative urine samples; and (2) using biomarker data from a population-based study and a PBPK model to demonstrate the challenges in linking urinary biomarker concentrations to intake doses for individuals. Results showed that the modeling approach was able to characterize the distribution of biomarker concentrations at the population level, but predicting the exposure-biomarker relationship for individuals was much more difficult. The type of information needed to reduce the uncertainty in estimating intake doses, for individuals, based on biomarker measurements is discussed. 相似文献

Improvements made on the direct NO2 photolysis actinometer developed by J. O. Jackson have produced more precise data. A plot of measured values of the photolysis rate J1 vs Eppley uv photometer readings produces a curved rather than the straight line correlation previously reported. This curvature arises from the Eppley and NO2 absorption spectrum overlap, backround surface albedoes, the Ep-pley's cosine response and inherent errors in the chemical equation used. New J1 measurement vs Eppley data is shown, and a procedure for calculating instantaneous J-i values from an Eppley output is suggested. 相似文献

Managing Baltic Sea fisheries under contrasting production and predation regimes: ecosystem model analyses 总被引:1,自引:0,他引:1
Based on an earlier published ecosystem model, we have explored possible effects of different management scenarios for the Baltic Sea. The scenarios include an oligotrophication of the system, a drastic increase in the number of seals, and changes in the fishery management. From these simulations we conclude that fisheries, seals, and eutrophication all have strong and interacting impacts on the ecosystem. These interactions call for integrated management. The modeling highlights the potential for conflicts among management mandates such as flourishing fisheries, rebuilt seal populations, and substantially reduced eutrophication. The results also suggest that fisheries management reference points have to be adjusted in response to changes in the presence of natural predators or ecosystem productivity. 相似文献
