Results of a large-scale survey of resource-poor smallholder cotton farmers in South Africa over three years conclusively show that adopters of Bt cotton have benefited in terms of higher yields, lower pesticide use, less labour for pesticide application and substantially higher gross margins per hectare. These benefits were clearly related to the technology, and not to preferential adoption by farmers who were already highly efficient. The smallest producers are shown to have benefited from adoption of the Bt variety as much as, if not more than, larger producers. Moreover, evidence from hospital records suggests a link between declining pesticide poisonings and adoption of the Bt variety. 相似文献

While the literature on ‘global care chains’ has focused on the international transfer of paid reproductive labour in the form of domestic service and care work, a parallel trend takes the form of women marriage migrants, who perform unpaid labour to maintain households and reproduce the next generation. Drawing on our work with commercially matched Vietnamese marriage migrants in Singapore, we analyse the existing immigration–citizenship regime to examine how these marriage migrants are positioned within the family and nation-state as dependants of Singaporean men with no rights to work, residency or citizenship of their own. Incipient discussions on marriage migrants in civil society discourse have tended to follow a ‘social problems’ template, requiring legislative support and service provisioning to assist vulnerable women. We argue for the need to adopt an expansive approach to social protection issues, depending not on any one single source—the state, civil society and the family—but on government action to ensure that these complement one another and strengthen safety nets for the marriage migrant. 相似文献

Most scholars agree that news coverage of politics is the product of complicated interaction between journalists and politicians. Yet, we know little about how the interaction affects the coverage. Our analysis examines U.S. senators' press events and subsequent national network coverage from 1980–1996. Our evidence suggests that all senators can increase journalists' interest in their press events by carefully choosing the type of event and which politicians attend. In turn, such interest often translates into actual news stories, although that coverage is not guaranteed. Thus, senators can structure press events in order to increase the likelihood of coverage, but reporters understandably resist their attempts to do so. As a result, the most newsworthy press events require senators to give up control over content, creating more potential for revealing unexpected information. 相似文献

This article reports an analysis of Americans' opinions about the news media's fairness in covering public affairs. The data come from the 1996 and 1998 National Election Studies, which contained variables tapping exposure to and opinions about the news media, as well as key political dispositions?partisanship, ideology, and opinion about presidential and congressional job performance?and a plethora of demographic variables. The data show that people who adhere to traditional moral codes and are misanthropic tend not to trust the news media to cover politics fairly. In a presidential election year, opinion about the president's job performance affects perceptions of the press's fairness. In an off-year election, however, opinion about the president's job performance is replaced by opinion about how the Congress has been doing its job. In addition, perception of how the media covered the Lewinsky scandal also influenced opinion about the press's fairness in general. 相似文献

Given the centrality of court interventions to the U.S. response to intimate partner violence (IPV), it is crucial to evaluate their impact on reabuse. To do so, this study examined whether female IPV victims’ experiences of abuse in the year following a criminal court case against their partner varied by case outcome or by whether the batterer had or had not been incarcerated. Consistent with prior research, we found no main effect differences in reabuse trajectories by court case outcome or by incarceration. We also examined variables that might moderate the impact of case outcome and incarceration on reabuse and found that although batterer legal history did not affect the impact of case outcome, his age, Time 1 employment status, the couple’s Time 1 living arrangement, and duration of abuse did interact with case outcome. No variables tested moderated the relationship between incarceration and reabuse over time. Findings suggest that in certain cases there may be benefits to case outcomes that leave potential consequences hanging over the offender’s head. These results also add to the growing body of evidence questioning the efficacy of one-size-fits-all approaches to IPV cases. 相似文献

Though the co-occurrence rate of intimate partner violence (IPV) and problems with alcohol and other drugs (AOD) is 50 % or higher among men in clinical samples, little attention has been given to examining the characteristics of batterers with AOD problems (AOD batterers). We compared 274 AOD batterers and 524 non-AOD Batterers (batterers who do not have AOD problems). Results indicated AOD batterers were more violent, and were more likely to perpetrate violence that is severe in nature. They also reported higher levels of anger and trauma, had a greater proclivity toward a borderline personality orientation, and were much more likely to use AOD during an incident of violence at least half of the time (41 % versus 9 %). Results underscore the need for screening of batterers for AOD problems and substance abusers for IPV, and suggest that AOD problems might serve as an important indicator to help identify particularly complex cases. 相似文献

The convergence of biological, technological and economic realms of life has fostered the development of the bioeconomy as a new feature of contemporary society. As the meaning of life and the human body is redefined in the context of the bioeconomy, new challenges have emerged for ethics and law In the face of these challenges, it is imperative that the currency of regulatory frameworks is maintained through the processes of regular review and update. The National Health and Medical Research Council has recently released the new National Statement on Ethical Conduct in Human Research to provide guidance for health research in Australia. The new National Statement will play an important part in supporting innovation and the development of the knowledge economy. 相似文献
