This article addresses regulatory reforms in the Indian telecommunications sector and emphasizes the role of the Indian judiciary. Our claim is that when confronted with a series of disputes relating to the nascent telecom regulatory landscape, the Supreme Court of India sought to make a constructive contribution to both the actual disputes as well as the overall regulatory framework. Our reading of these cases suggests that in the sphere of telecom, the Supreme Court has been less interested in stamping its own authority on issues, and has instead sought to bolster the authority and legitimacy of the recently constituted telecom regulatory institutions. We seek to draw attention to the role of the Indian judiciary as marking an exceptional feature of evolving regulatory systems in the Global South. Conventional wisdom in the regulatory jurisprudence that has evolved in the Global North suggests that judiciaries should have little or no role to play in regulatory systems. We suggest that to overcome the special challenges that regulatory systems in the Global South confront, more established institutions and actors might have to lend credibility and legitimacy to enable nascent regulatory actors to develop over time. At least in the Indian case, this is one way to understand the Indian judiciary's interventionist actions in the sphere of telecom regulation.  相似文献

Performance management techniques are presented as control mechanisms to save money and hold bureaucrats accountable, consistent with negative agency theory assumptions of bureaucrats. We propose an alternative theory of performance management that rests on prosocial values. This theory argues that public servants who see the social impact of their work are more likely to use performance metrics. We operationalize performance information use in terms of purposeful use for internal organizational means, and political use for external legitimation. Those who perceive that their work has a strong social impact are likely to pursue both types of uses, to improve both the effectiveness of their services, and to maintain resources. The data come from a cross‐sectional survey of U.S. public and nonprofit employees.  相似文献

Gordon Tullock is one of the world’s leading economists. Even more so than Chicago’s Gary Becker, Tullock has extended the rational choice model into areas previously judged to lie outside the realm of economics. This essay identifies Tullock’s contributions to constitutional political economy, public choice, bureaucracy, the law, and bio-economics. The essay focuses attention most especially on Tullock’s pioneering contributions to public choice, including his twenty-year editorship of Public Choice.  相似文献

This paper aims to unpack the dynamics of displacement and the relationship of physical movement to elements of space (i.e. land) and place (or identity), in the Sundays River Valley, near the town of Kirkwood, in the Eastern Cape, South Africa. It primarily uses the motif of frontiers to cast light on displacement as an ongoing phenomenon and explore the different eras of occupation of land in the Sundays River Valley, from the early nineteenth century until 1970. It relates different layers of belonging and identity to the unfolding of capitalism and apartheid in South Africa. The article argues that ties to land are multiple, contested and based upon dispossession and physical movement rather than upon stability. While such a high degree of contestation of oral evidence in the Sundays River Valley might not give current claimants a detailed legal basis for restitution, it is an academically valuable idea to explore the origins of the inhabitants in the Sundays River Valley – because it can indicate the degree to which local identities are influenced by experiences of disruption and displacement. The paper argues that frontier relationships in the SRV are central in the formation of larger systems of relationships of race and class, and that this casts new light on displacement (both as a historical event and a contemporary experience), in the formation of identity and place in southern Africa.  相似文献

This histological study of calvarian bones with the injuries inflicted by a shot from an Osa traumatic non-lethal pistol revealed nephrogenic osteopathy in the preceding period. The pathologically altered bone tissue was damaged by a relatively mild tangential traumatic impact. It is concluded that the possibility of such pathological changes should be taken into consideration in the forensic medical expertise of any trauma including gunshot injuries.  相似文献

Determination of sex from fragmentary crania is a critical problem in forensic anthropology. Osteometric analysis of mastoid can serve forensic anthropologists better in sex identification by virtue of the noticeable dimorphic characteristics. The present study aims to develop population-specific, sex-differentiating anthropometric standards for the mastoid process of North Indian skulls. Eight parameters of the mastoid region were measured on 138 adult crania (M/F 104:34, 22-65 years) and analyzed using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.000). In stepwise analysis, asterion-mastoidale and mastoid breadth have provided an accuracy of 87%. Receiver operating characteristic curves were obtained for each variable to observe their overall performance in sex determination. Posterior end of incisura mastoidea-depression of suprameatal triangle was found to be the best variable with maximum area under curve and highest predictive accuracy (82.6%).  相似文献

The 2 common carotid arteries bifurcate in the neck into the internal and external carotid arteries. The internal carotid artery enters the skull and further divides into the anterior and middle cerebral artery. During its short course in the neck, the carotid artery travels encased in the carotid sheath along with the vagus nerve and the internal jugular vein. During its course in the neck, the carotid artery is quite superficial, making it vulnerable to both penetrating and blunt traumatic injuries. We report here a case of a 40-year-old man who presented to the emergency department after sudden collapse and loss of consciousness a day after an attempted strangulation. Imaging revealed large hemorrhagic infarcts in the left anterior cerebral artery and middle cerebral artery territories as well as a smaller infarcts in the right anterior cerebral artery territory necessitating emergency decompressive hemicraniectomy. Our case report adds to the existing literature on nervous system injury due to strangulation. Physicians should be aware of the possibility of delayed presentation of neurological deficit after attempted strangulation.  相似文献
