The environmental security risk which Iraq poses to itself and its neighbors is considerable. Iraq's enormous investments in military industries, including weapons of mass destruction, well-documented practice of environmental warfare, and extensive aggression against internal ethnic minorities and neighbors, have created long-term ecological problems which have degraded the air, water, and soil, negatively effected public health, and intentionally displaced populations. These and many other problems will confront any successor regime and the international community. Some of the environmental problems and their causes are reviewed here. It is suggested that detailed study and planning should begin immediately to catalog and address the environmental legacy.  相似文献

Theoretical explanations of why rational individuals would participate in politics remain unsatisfactory. This paper addresses the problem by developing and analyzing models which include among citizens' payoffs “relational goods,” objectives which depend upon interactions among persons. The models predict more participation than do the standard approaches. For example, under some circumstances persons will be more likely to act if they believe others will act, contrary to free-rider logic. More importantly, conditions are identified under which leaders could increase mass activity. Thus, a model is provided of “mobilization” in terms of the preferences and decisions of a rational individual. The author thanks the Russell Sage Foundation for support as a Visiting Fellow during 1986–87. The paper has benefited from the comments of Patricia Gurin, Steve Brams, Jane Mansbridge, Linda Cohen, Tyler Cowen, Ami Glazer, and seminar participants at the University of Rochester.  相似文献

Two aspects of the relation between sexual difference and democracy are discussed: (i) the construction in classic contract theory of the 'natural' difference between the sexes as a relation of superiority and subordination; (ii) the peculiarities and paradoxes of women's standing as citizens as the 'different' sex. This is illustrated by the examples of motherhood - women have been seen as having a distinctive political duty as mothers, but motherhood is also seen as the antithesis of citizenship - by the difficulties surrounding women and consent, and by the questions raised by contemporary feminists about the meaning of ('normal') 'sex'.  相似文献

Abstract

When families with Section 8 housing vouchers move from inner‐city communities to the suburbs, are they more likely to move to neighborhoods with higher socioeconomic status and to perceive improvements in housing and neighborhood conditions than those who make local moves or those who first move to the suburbs but then return to the central city? Both crosstabular and logistic regression analysis are applied to a telephone interview sample of 300 Section 8 voucher recipients in Oakland and Berkeley, CA.

As predicted, compared with the other two groups, suburban‐bound movers were more likely to move to neighborhoods with higher socioeconomic status and to experience better residential conditions, even when relevant background characteristics were controlled. Furthermore, few suburban‐bound movers experienced adjustment problems with neighbors or landlords, and their children quickly and smoothly adjusted to their new schools. The implications of these results for the Section 8 housing voucher program are discussed.  相似文献

The Metropolitan Police Service currently uses cotton swabs to retrieve DNA for forensic profiling. Recently, a new nylon flocked swab type has become available from Copan (MicroRheologics, Brescia, Italy) that it is claimed, offers increased sample recovery and release yields. If true, the flocked swab may have important applications in DNA evidence retrieval. This study examines the DNA retrieval capability of cotton and nylon flocked swabs when extracted using three common extraction platforms (QIAcube, BioRobot EZ1 and manually processed QIAamp DNA investigator kit). Results indicate that both swab types are capable of recovering high percentages of DNA (>50%); however, the extraction platform selected was shown to have a significant effect upon DNA retrieval. Across all experiments, the cotton swab combined with the spin-column extractions was shown to be most effective, with the nylon swab and BioRobot EZ1 combination being the least effective. These findings illustrate the importance of extraction method selection.  相似文献
