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 failure of forestry to contribute to poverty reduction in Central America is due to public policies which inhibit its profitability. Absence of public regulation of harvesting and competing subsidies to agriculture keep forestry stumpage prices artificially low. This encourages destruction of the forest resource, which damages both the environment and the potential to reduce poverty. A comparison of Costa Rica and Honduras reveals two dissimilar approaches toward forest policy. While Costa Rica attempts to raise producer and grower stumpage prices by tax credits, soft loans and differential species fees, Honduras enforces price ceilings and uses centralized authority to control forest production and export. Both countries exhibit weaknesses in the management control cycle of programming, budgeting, implementing and evaluating their forest policies. Yet the Costa Rican approach has increased stumpage prices already, which bodes well for their forest sector. By contrast, the major beneficiary of Honduran forest policy has been COHDEFOR, the state enterprise responsible for forestry management, controlling production, and running its national system of agroforestry cooperatives. Despite greater public authority and resources than the Costa Rican forest service (DGF), the Honduran forest policy is not likely to increase producer profitability or reduce poverty in the near future.  相似文献

Provincial governments in the Netherlands have only one general tax at their disposal. However, it has become an insufficient source of revenue for this level of government in the Dutch system. To increase the revenue raising capacity of the provincial governments, thirteen broad-based general tax proposals not used at the local level were examined. The objective was to find a fair and equitable tax that could easily be collected and would result in fl. 200 million in additional revenue for the provincial governments.  相似文献

Discussion of rape by soldiers as a form of persecution haslargely been directed towards the context of war or actual conflict.Nevertheless, there is a need for attention to be directed towardsthe phenomenon of rape within the military in the post-conflictperiod. This article discusses asylum claims presented in Norwayby Eritrean female soldiers claiming risk of persecution inthe form of sexual violence, rape, or torture within the military.First, presentation is made of the history of Eritrean women'sparticipation in the war of independence and the ensuing politicaland legislative gains won at the end of the war against Ethiopia.Review of Eritrea's report and responses to the Committee onthe Elimination of Discrimination Against Women (CEDAW) reveala state of backlash against women in the post-conflict period.Second, examination of how rape within the military and desertionmay fall under the criteria of the definition of a refugee accordingthe 1951 Convention on the Status of Refugees is pursued. Comparisonis drawn to instances of rape of women soldiers in the US andIsrael, as well as sexual violence by United Nations Missionin Ethiopia and Eritrea (UNMEE) peacekeepers, revealing commonchallenges affecting prevention and protection strategies. Third,a comparative review is conducted of evidentiary standards inorder to highlight the importance of maintaining a flexibleapproach responsive to the special circumstances of sexual violence.The Norwegian practice indicated a tendency to provide protectionfor compassionate grounds or humanitarian protection, ratherthan asylum. This resulted in non-recognition of the legitimacyof claims based on gender related persecution as requiring legalprotection under the 1951 Convention on the Status of Refugees.  相似文献
