While global consensus on the meaning and application of the responsibility to protect (R2P) principle remains tenuous, there is little contention among major actors that the development of the norm should prioritise the prevention of mass atrocities. In particular, Brazil, Russia, India, China and South Africa (BRICS) – which have a role to play that is vital to the future development of R2P as a global norm but which continue to express reservations about the intent and application of the doctrine – have been strong advocates of the preventive aspects of the principle. This rhetorical consensus, however, belies the conceptual and practical challenges that are associated with the prevention of mass atrocities. In this paper, the example of South Africa’s post-conflict reconstruction and development (PCRD) interventions in South Sudan from 2005 to 2013 is used to reflect on the role of external actors in supporting conflict-affected states to implement the preventive aspects of R2P. It is argued that while South Africa, like other BRICS countries, has used the rhetoric that atrocity prevention should be at the core of R2P to legitimise its opposition to military intervention for humanitarian purposes, it has struggled to back this rhetoric with coherent strategies and concrete actions to prevent mass atrocity crimes within its sphere of influence. The gap between rhetoric and practice in the preventive aspects of R2P is not unique to South Africa, but highlights fundamental difficulties inherent to global efforts to prevent mass atrocities. 相似文献

共产党人的政治自信,是其对自身价值追求的充分肯定和坚定信仰。正是由于中国共产党始终代表人民群众的最根本利益,始终深入人民群众汲取集体智慧,始终依靠人民群众推动社会实践,始终服务人民群众造福广大百姓,共产党人才能充满政党自信、理论自信、道路自信和制度自信。能否真正坚持“来自人民、为了人民和依靠人民”的群众路线,是检验共产党人是否真正政治自信的试金石。 相似文献

This article presents two meta‐ranking models that minimize or nearly minimize violations of past game results while predicting future game winners as well as or better than leading current systems—a combination never before offered for college football. Key to both is the development and integration of a highly predictive ensemble probability model generated from the analysis of 36 existing college football ranking systems. This ensemble model is used to determine a target ranking that is used in two versions of a hierarchical multiobjective mixed binary integer linear program (MOMBILP). When compared to 75 other systems out‐of‐sample, one MOMBILP was the leading predictive system while getting within 0.64% of the retrodictive optimum; the other MOMBILP minimized violations while achieving a prediction total that was 2.55% lower than the best mark. For bowls, prediction sums were not statistically significantly different from the leading value, while achieving optimum or near‐optimum violation counts. This performance points to these models as potential means of reconciling the contrasting perspectives of predictiveness versus the matching of past performance when it comes to ranking fairness in college football. © 2013 Wiley Periodicals, Inc.
