Risk Perception of Heavy Metal Soil Contamination and Attitudes toward Decontamination Strategies

Contaminated soils are a common environmental risk all over the world. One major source of risk is heavy metal soil contamination caused by industrial emissions. This quasiexperimental study investigated the perception of these risks by exposed and nonexposed people, their attitudes toward bioremediation methods using hyperaccumulating plants, and the influence of long-term aspects of sustainability on the acceptance of bioremediation methods. Major findings were that people living in a contaminated area perceived the risk of the heavy metal soil contamination as higher than the general risk of contamination. Second, a factor analysis showed that the factors dread, control, and catastrophic potential were relevant for the perception and valuation of low-dose environmental risks such as the contamination of the investigated area. In addition, a cluster analysis showed that the risk of heavy metal soil contamination was perceived as similar to that of oil contamination, ozone layer, preservatives and genetic technology. It was perceived indifferently with regard to dread. The uncontrollability of heavy metal soil contamination was estimated as medium, and its catastrophic potential as low. Third, exposed and nonexposed participants preferred bioremediation methods to classical methods (e.g., excavation and chemical treatment of the soil), because they perceived the environmental and esthetical performance of the bioremediation as important criteria. Sustainability or precautionary issues, such as the prevention of harm for future generations, were highly correlated with the acceptance of the use of bioremediation methods in people's residential areas.     

Affirmative action in winner-take-all markets

Whom to hire, promote, admit into elite universities, elect, or issue government contracts to are all determined in a tournament-like (winner-take-all) structure. This paper constructs a simple model of pair-wise tournament competition to investigate affirmative action in these markets. We consider two forms of affirmative action: group-sighted, where employers are allowed to use group identity in pursuit of their diversity goals; and group-blind, where they are not. It is shown that the equilibrium group-sighted affirmative action scheme involves a constant handicap given to agents in the disadvantaged group. Equilibrium group-blind affirmative action creates a unique semi-separating equilibrium in which a large pool of contestants exerts zero effort, and this pool is increasing in the aggresiveness of the affirmative action mandate.     

The global animus: in the tracks of world consciousness

In recent years, much has been made of the idea that under conditions of globalization, more and more people in different parts of the planet conceive of themselves as part of a ‘global society’ or ‘global culture’. Often it has been alleged that forms of consciousness centred around a disposition to see one's own life as a single part of the ‘world as a whole’ are relatively recent products. In this paper we argue that such tendencies, or something very much like them, in fact were present in the ancient Mediterranean world. We examine how ways of thinking and feeling, that bear in certain ways close correspondence to modern ideas as to ‘globality’, were prevalent amongst certain social groups in the Roman empire. Those persons regarded themselves as part of a world that was rapidly shrinking through increasing levels of political, commercial and other modes of interconnection between its geographically disparate parts. By examining these ancient attitudes, we demonstrate an important aspect of the pre-history of modern sensibilities as to the nature of a ‘globalizing/globalized world’. Moreover, by attending to ancient evidence as to ‘global’ attitudes and ‘global consciousness’, one may begin to overcome the presentism implicit in many contemporary accounts of globalization.     

When do couples sign the one-child certificate in urban China?

This paper analyzes a central part of China's one-child policy: when do eligible couples sign the one-child certificate and what are important socioeconomic determinants of this decision? We use proportional hazard models applied to micro-data from the 1985 Chinese Fertility Survey to study this question. Our results for urban residents in Hebei and Shaanxi indicate that a couple's socioeconomic characteristics significantly affect the timing of signing the certificate. In particular, education of the husband and wife, household wealth, and the age at marriage increase the probability of signing the certificate at an earlier time, while living space decreases the probability. Living in extended family structure or a male first child (to test for son preference) apparently have little effect.
