The manner in which President Karimov's roles were recognized in the global arena affected how Uzbekistan's international relations developed – a perspective that highlights both the form and the content of bilateral relationships. While mutual interests are crucial to beginning a relationship, it is also important to understand how those relations were recognized in public and dealt with in private. If partners managed to recognize Karimov's agenda publicly, or at least act with discretion, this tended to create an atmosphere favouring cooperation. As such, recognition and discretion reveal much about Karimov's concerns with international equality and self-reliance, pointing to the reasons why Uzbekistan's relations fluctuated more with some actors than others. The United States and Germany are ideal examples of that ambivalent situation: Washington often cooperated with Uzbekistan on security matters, but then saw its military personnel excluded from Qarshi-Qanabad after the 2005 Andijan crisis; whereas Berlin witnessed little change in its relationship with Uzbekistan and continued to lease a base in Termez after 2005. This difference in outcomes can be explained in part by a dynamic of recognition and discretion. 相似文献

Cristina Cordeiro M.Sc. Rafael Seoane Ph.D. Ana Camba M.Sc. Elena Lendoiro M.Sc. María S. Rodríguez‐Calvo Ph.D. Duarte N. Vieira Ph.D. José I. Muñoz‐Barús Ph.D. 《Journal of forensic sciences》2015,60(5):1346-1349
Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation. 相似文献

The paper contains a conceptual analysis of "act of toleration" and the property of "being tolerant". Being tolerant is understood as a dispositional property of persons manifested in what the author calls the "circumstances of toleration". The main circumstances distinguished are: a tendency to prohibit a certain behaviour and the competence to determine the deontic status of the behaviour in question. An act of toleration, then, consists in not prohibiting (or cancelling the prohibition of) that behaviour. It is argued that this requires the existence of two different normative systems, the "basic system", and the "justifying system". Acts of toleration must be based on reasons coming from the latter. This insight enables one to establish a difference between reasonable and unreasonable toleration, as well as between toleration and related concepts like indifference, acquiescence, etc. The analysis also introduces the distinction between "vertical" and "horizontal" toleration. Acceptance of this last category implies that toleration does not necessarily require hierarchical relationships between those who tolerate and those whose actions are tolerated. 相似文献

This paper deals with double lobbying: several bureaucratsparticipate in joint lobbying to get a high total departmental budget, butthey also engage in antagonistic lobbying to reap as high a share of thetotal budget as possible. The antagonistic lobbyingconstitutes a contest among the bureaucrats. This papercharacterizes the Nash equilibria in lobbying and shows inwhich way exogenously fixed bureaucratic incomes induce thesame or different lobbying behavior as incentive incomes. 相似文献

The authors evaluate the consequences of incomplete necroscopic examinations wherein it was impossible to apply radiological resources to locate firearm projectiles. The study includes 8185 reports from the Instituto Médico-Legal Afranio Peixoto in Rio de Janeiro, Brazil, representing the totality of corpses processed from January to December 2001; of these, 3122 were gunshot victims, 309 of which were buried with unremoved projectiles, being liable to future judicial reappraisal. During the same period, there were 23 exhumation requests by police authorities, 12 of them querying the existence of projectiles. The authors looked into the formal reasons assumed by the medico legal experts to conclude their reports from incomplete examinations, and suggest that gunshot necroscopic examinations should follow specific protocols, as incomplete autopsies will require further exhumations, at unnecessary additional costs. 相似文献
