In aerobic organisms, oxygen is a critical factor for tissue and organ morphogenesis from embryonic development throughout the adult life. It regulates various intracellular pathways involved in cellular metabolism, proliferation, cell survival and fate. Organisms or tissues rapidly respond to changes in oxygen availability by activating complex signalling networks, which culminate in the contr...

Economists argue that policymakers should take advantage of market principles in designing environmental regulations. Such market-based approaches – environmental taxes and cap-and-trade – use economic incentives to achieve environmental goals at lower costs. Market-based approaches have now become common due to near-unanimous advocacy by economists and early positive policy experiences. Despit...

Many developing countries are mixed economies in which public and private firms engage in Cournot competition. We show that some fundamental results in environmental economics fail to hold in these economies: more stringent environmental regulation does not necessarily reduce pollution levels, the equivalence between environmental taxes and standards breaks down, and not every emission level ca...

Environmental epigenetics Traditional research on the combined effects of genetics and the environment investigates how individuals differ in susceptibility to disease and how susceptibility changes over time. The majority of these gene–environment interaction studies focus on genetic sequence variants, including single nucleotide polymorphisms (SNPs), which influence toxicant uptake, metabolis...

In a market where consumers are not fully informed about the actual production technology or environmental performance of firms that engage in strategic competition, I study the effect of environmental consciousness of consumers on the incentive to invest in cleaner technology. Firms compete in prices and may signal their environmental performance to uninformed consumers through prices. I also ...

Article history: Received 9 August 2010 Received in revised form 20 May 2011 Accepted 28 August 2011 Available online 21 September 2011 Globalization has caused Chinese manufacturers to develop quickly while simultaneously meeting green barriers to export products. Whether internationalization has led to improved environmental management practices among Chinese manufacturers is also a related q...

Efforts toward controlling secondhand smoke in public places have been made throughout China. However, in contrast to the western world, significant challenges remain for effectively implementing smoke-free regulations. This study explores individual and regional factors which influence smoking in smoke-free public places. Participants included 16 866 urban residents, who were identified throug...

New approaches should be considered as the US Environmental Protection Agency (EPA) moves rapidly to develop new beach monitoring guidelines by the end of 2012, as these guidelines serve as the basis by which states and territories with coasts along the oceans and Great Lakes can then develop and implement monitoring programs for recreational waters. We describe and illustrate one possible appr...

There is a widespread repeated exposure of the population to the pesticides and heavy metals of occupational and environmental origin. Such population is forced to undergo continuous stress imposed by combined exposure of the heavy metals and different classes of the pesticides used in agricultural as well as health practices. The existing reports from several workers have indicated that heavy ...

The flagship of the Environmental Protection Agency's regulatory reinvention initiative, Project XL has been touted as a regulatory blueprint for a site-specific, performance-based pollution-control system, but widespread complaints about the costs of the program beg the question of whether the costs of tailoring regulations to individual facilities are manageable. To address this question, thi...
