Globalization critics argue that international trade spurs a race to the bottom among national environmental standards. ISO 14001 is the most widely adopted voluntary environmental regulation which encourages firms to take environmental action beyond what domestic government regulations require. Drawing on a panel study of 108 countries over seven years, we investigate conditions under which trade linkages can encourage ISO 14001 adoption, thereby countering environmental races to the bottom. We find that trade linkages encourage ISO 14001 adoption if countries' major export markets have adopted this voluntary regulation. 相似文献

The temptation to free ride and the fear of exploitation are traditionally offered as factors explaining individuals' choices under conditions of social dilemma. In two experimental studies of prisoner's dilemma behaviour we demonstrate that the ratio-differences of payoffs are as important as the absolute differences in affecting the likelihood of cooperation. The implications of this additional structural determinant of dilemma choice are developed and applied to the stalled gains debate in international relations theory. By incorporating ratio-differences into the analysis 'realist' and 'liberal' theories of state behaviour may be reconciled. 相似文献

We investigated the relation between urban psychosocial stressors and intimacy achievement in a sample of 59 African American, Hispanic American, and White adolescent fathers-to-be. Participants received an intimacy score based on Orlofsky's Intimacy Status Rating Scale. Those with higher cumulative psychosocial stressors had lower levels of intimacy. One psychosocial risk factor, low interpersonal empathy, was significantly associated with intimacy levels. African Americans had lower levels of intimacy than Hispanic or White participants. 相似文献

Several empirical studies have suggested that legislators engage in a surprisingly large degree of on-the-job consumption, or ideological behavior. These findings cast doubt on the hypothesis that legislators can be modelled as though they seek to maximize political support. This paper attempts to determine whether commonly used proxies for ideology in fact represent behavior to which voters are averse. The results show that legislators who engage in more of this behavior lose general-election support without generally receiving compensating increases in partyprimary support. A corollary to this result is that voters punish shirking legislators significantly. 相似文献

The cold war dominated American perceptions of the People's Republic of China during the 1950s and 1960s, and opinions of China were correspondingly negative. Improved Sino-American relations, accompanied by domestic reforms in China, led to a gradual improvement in American attitudes toward China during the 1970s and 1980s. By the late 1980s, Americans held positive perceptions of China and its relations with the United States, but continued to view the People's Republic as communist and undemocratic. This sort of inconsistency is characteristic of periods of cognitive transition: some established perceptions are slower to change than others, and this results in structural imbalance. The Tiananmen Square massacre of June 1989 interrupted this transitional process and sent perceptions of China shooting back toward balanced, cold war stereotypes. The massacre set the Chinese government in a clear symbolic struggle against freedom and democracy. This rekindled latent cold war images of China and elicited disapproving rhetoric from American leaders. The result was a quick reversion to negative perceptions of China, structured by a lingering cold war schema. These processes are demonstrated through the presentation of a study that explores the cognitive structure of perceptions of China both before and after the massacre. 相似文献

Retrospective analysis of autopsy findings in 60 infants who had been found unexpectedly dead in their cribs or beds in South Australia from 1994 to 1998 was undertaken to determine the diagnostic usefulness of individual stages in the postmortem investigation. Positive findings occurred in 2 of 43 scene examinations (3%), 2 of 60 external examinations (3%), 2 of 11 radiologic examinations (18%), 8 of 60 internal examinations (13%), 7 of 60 histologic examinations (12%), and 3 of 58 microbiologic examinations (5%). No positive findings were detected on toxicologic screening. Not every case underwent each diagnostic step. This gave alternative diagnoses to sudden infant death syndrome (SIDS) in 15 cases (25%). This study demonstrates an increase in the percentage of cases of unexpected infant death due to causes other than SIDS; it also shows the diagnostic yield of individual stages in the postmortem evaluation of such cases. Negative findings were important in giving validity to the diagnosis in the 45 cases that were ultimately designated as SIDS. 相似文献
