The increasing availability of urban social indicators offers the possibility of an overall quality of life measure which can be used to compare cities. Several solutions to the problem of combining the individual indicators into an overall comparative measure are considered in this article. The most promising results were obtained by grouping cities according to the similarity of their profiles on the social indicators. Yet the value of the comparisons remains speculative because of serious limitations in the indicators. While a number of improvements are possible, the resulting indicators will still only be adequate for use in gross comparisons of metropolitan areas.  相似文献

Despite the CIA's improved analytical tradecraft and increased resources, the future of its analytic mission remains in doubt. Post-9/11 improvements have been coupled with a continued focus on current intelligence priorities that minimize attention to the development of strategic research and deeper knowledge. Simply increasing the number of analysts has not produced deeper expertise. The CIA's traditional recruitment and training methods, as well as its rewards and promotion system, encourage analysts to avoid concentrating on any single area of regional or functional expertise in favor of moving around the agency to build a successful career. A continued reliance on risk-avoidance security practices also restricts analysts' contact with non-government and foreign experts who often have needed political and cultural knowledge of intelligence topics. To rectify these inadequacies, the CIA's analytic directorate needs to develop incentives for analysts who wish to develop more strategic analysis and remove the security barriers to closer collaboration with experts outside the US government. Developing cross-agency analytic collaboration would also maximize expertise and would benefit from intelligence community-wide training programs similar to what the US military does at its senior service colleges.  相似文献

Levinas's ethics claims to show the path to a better society. But an examination of his views on politics and the State shows that this ethics is not much more than a justification of theology and of the State of Israel.  相似文献

The collapse of Greece's premier terrorist organization, the 17 November (17N) group, back in the summer of 2002 was a truly dramatic event, considering 17N's 27-year career, but it was not such a watershed event in the country's history as it was presented at the time by the mainstream political and media establishments. 17N's dismantling and imprisonment, far from demoralizing and emasculating the armed struggle movement, led to the emergence of new urban guerrilla groups and the increase and intensification of revolutionary violence. This article reassesses Greece's persistent terrorism problem by focusing on the nature, threat, and operational evolution of a new generation of political militancy.  相似文献

In this introduction, we review the literature on intellectual property rights and access to medicines, identifying two distinct generations of research. The first generation analyzes the origins of new intellectual property rules, in particular the World Trade Organization’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the significance of TRIPS to developing countries. The second generation examines national-level experiences, as countries adjust their laws and practices to conform to TRIPS. Based on the insights provided by the articles in the special issue, we contribute to the second generation by considering a pair of overarching sets of issues. First, we highlight the domestic political challenges that affect how countries go about implementing their new obligations under TRIPS. We argue that alliances and coalitions are necessary to underpin the use of policy instruments designed to conform to TRIPS while taking into account local conditions and needs, and we present insights that allow us to understand why alliances and coalitions are difficult to construct and sustain in this area. Second, we explain why policies that many countries adopt in response to TRIPS often do not generate their desired or intended outcomes. In the last section of the introduction, we review the articles that appear in this special issue.  相似文献

The Singapore Statement on Research Integrity, articulated during the 2nd World Conference on Research Integrity in 2010, encompasses principles that apply to all research endeavours, including the various disciplines that comprise the field of forensic science Singapore Statement on Research Integrity (2010) (https://wcrif.org/guidance/singapore-statement). Cases of research misconduct and breaches of research integrity in any field undermine the trustworthiness of research and make it difficult if not impossible for others to rely upon and replicate research results. Moreover, problems in the research environment, whether in the academic, public, or private sector, can include bullying and harassment, discrimination, abuse of power and corruption, as well as competitive pressures related to employment and status.  相似文献
