Jorge Sanjinés' 1960s films Revolución and Ukamau challenge the class and ethnic hierarchies of Bolivian society by casting the proletarian and indigenous masses as revolutionary liberators. The new national imaginary they evoke is tightly bound to the experimental cinematic techniques they employ, since their rejection of rationalist, realist aesthetics signals a partial undermining of the linear time of the modern nation. Ukamau both recalls and resists previous Bolivian indigenismo, which sought to co‐opt the Indian into a national mestizo consciousness. Its exoticist portrayal of the Indian ultimately limits its political effectiveness, but textual and contextual analyses show subversive Indian agency leaking through.  相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages.  相似文献

The accountability of international development NGOs (INGOs) has attracted a great deal of interest from academics and development practitioners. INGO accountability falls into two categories: practical accountability (for the use of inputs, the way activities are performed, and outputs) and strategic accountability for INGOs' performance in relation to their mission. This article presents a conceptual framework for exploring INGO accountability. It is based on information collected through a literature review and semi-structured interviews with representatives from 20 UK-based INGOs. The research found that INGOs tend to use a number of quality-assurance mechanisms to achieve ‘practical’ accountability. However, it is suggested that this kind of accountability will not necessarily enable INGOs to achieve their missions to alleviate poverty and eliminate injustice. Furthermore, the predominant use of practical accountability has led to a number of gaps in INGO accountability. It is suggested that, like the term ‘participation’ before it, accountability has been co-opted for its instrumental benefits to INGO project performance and management. It is argued that if INGOs are to achieve their missions, this will require more ‘strategic’ forms of accountability, geared towards fundamentally changing those social, economic, and political structures that promote poverty.  相似文献

Corporate governance theory suggests that companies with dispersed and indirect ownership suffer from agency costs. A worst case is where several political authorities jointly own a company, which allows managers to operate with inferior efficiency. In political economy, the manager is not the major agency problem. Elected politicians may impair efficiency to improve their re‐election prospects. Since politicians have less influence in jointly owned firms, such companies are expected to perform better than those owned by a single public authority. Consistent with corporate governance – but not political economy – the empirical analysis suggests that dispersed municipal ownership impairs cost efficiency. In the Norwegian case of municipal refuse collection presented here, costs of dispersed ownership often outstrip gains from economies of scale. Use of jointly owned companies is not necessarily a proper response to efficiency problems inherent a fragmented local government structure.  相似文献

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

Conclusion In 1984, after years of study and thorough debate, a bipartisan majority of the Congress enacted perhaps the most far-reaching reform of the federal criminal justice system in the history of the United States. The Sentencing Reform Act and the federal sentencing guidelines are now beginning to produce data indicating that the objectives of avoiding unwarranted disparity and invidious discrimination are being achieved.After an uncertain beginning, the guidelines are gaining acceptance by courts and criminal justice practitioners. As one appellate court observed in admonishing lower courts that the guidelines must be respected:We have embarked on a new course. Only time will tell whether the use of the guidelines will result in an improvement over the old system. But unless we follow the spirit and written directions of the guidelines, we will never know if they have been given a fair test. They at least deserve that.Indeed, the bold new approach to sentencing that is being followed today in federal courthouses throughout the United States deserves an opportunity to succeed, given its many beneficial features and the lofty goals toward which the reforms are directed. While ample work remains for the United States Sentencing Commission to monitor and improve the guidelines, indications at this still early date are that the experiment is succeeding.An earlier version of this paper was presented at the fifth conference of the Society for the Reform of Criminal Law, Parliament House, Edinburgh, Scotland, August 5–9, 1990.
