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

This article examines the use of Eye Movement Desensitization and Reprocessing (EMDR) in helping a client address problems with persistent anxiety and a lack of self-esteem. During EMDR treatment, the client explored the dichotomous thinking that had plagued her since childhood, and correspondingly, the role of childhood physical and emotional abuse in her chronic feelings of inadequacy and anxiety. The client experienced significant improvement in her levels of anxiety and problems with self-esteem, both at the end of treatment and at 1-year follow up. Qualitative and quantitative data are utilized in this case study outlining the use of EMDR with a client diagnosed with dysthymic disorder.  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 concern driving current debate on agricultural extension is increasingly that of how to help farmers learn how to deal with the complex world around them responsibly and profitably, in such a way that the extension worker is ancillary. This article seeks to deconstruct and provide a more reasoned assessment of agricultural extension services through a reflection on development paradigms, adult education, individual empowerment, and institutional pluralism. By calling into question the underlying ethical dimensions of agricultural extension, it is possible to develop an alternative paradigm and thereby generate new insights into it. The article concludes that the raison d'être of agricultural extension today must be to create an ethical basis which ensures that extension practices are more inclusive and thus responsive to the needs of farmers and other rural populations, integrating individual expectations into the wider socio-economic, cultural, political, and geographical environment.  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

幼年牦牛松果体的光镜和电镜观察   总被引:1,自引:0,他引:1  
利用光镜和电镜技术对幼年牦牛松果体的组织形态结构特征进行了研究。结果表明,光镜下,幼年牦牛松果体由松果体细胞、少量的神经胶质细胞、毛细血管和神经等组成。电镜下,松果体细胞的电子致密度低,细胞质内含有丰富的线粒体、粗面内质网、滑面内质网、高尔基复合体、微管、微丝和核糖体,典型异质细胞器突触带呈球形,多位于质膜附近。神经胶质细胞内的线粒体丰富,胞体突起呈球形膨大伸入到松果体细胞之间。松果体细胞以及神经胶质细胞间均存在突触和连接复合体。牦牛松果体内的毛细血管为连续型,远腹侧血管周围可见色素细胞。  相似文献
