Global climate change is now one of the biggest challenges facing humankind in the twenty-first century. It is occurring at a time when China's economic rise is leading to substantial environmental problems combined with escalating demands on global resources. Many commentators have warned of impending economic collapse, rising social conflicts, and large-scale public health disasters. 1 It is not only China's modernisation drive that is at stake. The spill-over effects across borders also present security concerns at the regional and global levels. From a global security perspective, the emerging environmental crisis is generally cast in highly negative terms. Limited attention has been given to the question of whether China can adapt. In the case of climate change this is now an urgent task. On the Qinghai–Tibetan plateau climate impacts pose significant security risks for China and the Asia region. The ability to adapt is of critical importance to the future sustainability of these ecosystems as well as the millions of people they serve.  相似文献

J.S. Mill's support for colonialism and empire has attracted recent critical attention in the context of debates about his status as a modern egalitarian liberal, and liberalism's historical justification for empire. While Mill defended imperialism for most of his life on the grounds that it brought progress and civilization to historically backward peoples, his later correspondence reveals that he became increasingly concerned that settler violence against subordinated populations, notably in New Zealand, India and the West Indies, undermined the civilizing mission. Mill had been a strong advocate for settler societies in Australia and New Zealand, but came to fear that colonial abuses of power over indigenous peoples would vitiate the utilitarian benefits of colonial self‐rule.  相似文献

Adolescents have begun to initiate sexual activity at increasingly early ages in the past few decades. Using a sample of 2,494 adolescents from the National Longitudinal Survey of Youth (NLSY97), structural and parental process variables were examined in the prediction of sexual onset. Results indicated that the age at which youth initiate sexual intercourse is related to the structural characteristics of their grandmothers and mothers, as well as puberty, gender, and race. There is support for partial mediation of the effects of these grandmother characteristics via mother characteristics and parental process. Results are discussed within the framework of the life course perspective and provide support for the importance of previous generations in the explanation of adolescent sexual behavior. Implications for families and adolescents are also addressed. Katherine A. Johnson, is a doctoral student at the University of Nebraska–Lincoln. Her research interests include the study of crime, gender, and high-risk youth using both qualitative and quantitative methodology. Kimberly A. Tyler, is an associate professor in the Department of Sociology at the University of Nebraska–Lincoln. Her research interests include homelessness, child abuse and neglect, victimization, and high-risk behaviors among adolescents and youth.  相似文献

This article discusses the issue of domestic violence in the postdivorce context and how abused women who have children with their abusers are at a particular high risk of becoming victims of this phenomenon. It discusses recent state legislation that has been enacted to deal with the problems of domestic abuse after divorce. More specifically, this article looks at the American Law Institute's proposed model statute on child custody and visitation and how it addresses the issue of domestic violence both during and after divorce. This article will also explore potential flaws of the American Law Institute's model as well as some ideas for further development in this area .  相似文献
