The case for free market environmentalism

Environmental Ethics is the ethics of how we humans are to relate to each other about the environment we live in. The best way to adjust inevitable differences among us in this respect is by private property. Each person takes the best care of what he owns, and ownership entails the free market, which enables people to make mutually advantageous trades with those who might use it even better. Public regulation, by contrast, becomes management in the interests of the regulators, or of special interests, such as lovers of rare species-not the people they're supposed to be serving.     

Impacts of foreign investment on sustainable development in a Chilean mining region

The desert mining region of Antofagasta, Chile, enjoyed spectacular economic growth in the 1990s as a result of foreign direct investment (FDI), mainly in the exploitation of the region's rich copper deposits. In a country considered by international financial institutions to be a good example of economic performance, Antofagasta has been termed a model region,and Chile's economic and social development in the 1990s has been considered a suitable model for other Latin American countries. However, development indices based on statistical data must be examined with caution, as human welfare does not necessarily keep pace with economic growth. This article analyses the Antofagasta Region in terms of problems that may occur in conjunction with accelerated economic growth, and how these can affect the environment, as well as the regional labour market. The article also examines a regional economic strategy for Antofagasta recently proposed by the local government, and suggests new alternatives for the sustainable economic development of the region.     

Experience with airborne detection of radioactive pollution (ENMOS, IRIS)

This paper discusses the advantages of airborne monitoring of radioactive pollution and shows example maps indicating manmade pollution from different sources. The sensitivity of airborne radioactive detection is discussed. Comparisons of airborne and different ground measurements are presented. New instrumentation for airborne or ground moving vehicles is briefly described. Airborne footprinting provides rapid, well-defined spatial images of natural and manmade radioactive contamination. Data acquisition integrated with GPS navigation provides consistent data and guarantees proper data location. Real-time airborne measurements are re-calculated, with the use of special algorithms, into absolute units for individual radioactive nuclei contamination of the ground together with dose calculation. Raw records and calculated data are provided after enhanced post-flight processing. Dose rates and detection of different radioactive elements are presented.

Summary of regulatory/policy/economic issues related to nitrogen

This is a summary of the two presentations from the session that dealt with the regulatory, policy and economic issues related to nitrogen compounds and the need to reduce their emissions. The papers were presented by Ronald Evans and Jan Willem Erisman. Information on ecological impacts of nitrogen species and atmospheric relationships are presented in other papers in this special issue. This summary provides an overview of the discussions from the above presentations.     

Phyto/rhizoremediation studies using long-term PCB-contaminated soil

Purpose  

Polychlorinated biphenyls (PCBs) represent a large group of recalcitrant environmental pollutants, differing in the number of chlorine atoms bound to biphenyl ring. Due to their excellent technological properties, PCBs were used as heat-transfer media, for filling transformers and condensers, as paint additives, etc. With increasing knowledge of their toxicity, transfer to food chains and accumulation in living organisms, their production ended in most countries in the 1970s and in 1984 in the former Czechoslovakia. But even a quarter of century after the PCB production ceased, from contaminated areas, the volatile PCBs evaporate and contaminate much larger areas even at very distant parts of the world. For this reason, PCBs still represent a global problem. The main method of PCB removal from contaminated environment is at present the expensive incineration at high temperatures. With the aim of finding effective alternative approaches, we are studying biological methods for PCB removal from the environment. In this paper, we summarise 10 years of studies using long-term PCB-contaminated soil from a dumpsite in South Bohemia, targeted for the use of plants (phytoremediation) and their cooperation with microorganisms in the root zone (rhizoremediation).     

The differential effect of organizational induction process on early work role adjustment

Early work role adjustment is hypothesized to be a function of previous work experiences, early organizational experiences, and personality differences. Formal collective induction into an organization was compared with informal individual induction. Induction mode was the dominant variable which predicted adjustment four months after employment. Formal collective induction contributed to higher job satisfaction and lower work/family conflict. The mode of induction did not affect team cohesion, role conflict, role ambiguity, or perceived worker influence in the workplace. Self-monitoring, a personality variable, contributed to the prediction of work/family conflict. Inducation mode did not interact with other independent variables in predicting job satisfaction or work/family conflict.
