Large-scale privatization is an unfamiliar area of public policy. The practice and study of property reforms and privatization needs to include mesolvel phenomena such as laws, regulations, institutions and standard operating procedures. There has been little comparative analysis of privatization programs around the world. The author argues that analysts should compare the most immediately relevant institutional environment of the enterprise. Conceptually, this mesolevel system is situated between the firm and the macroeconomy. This system of action is especially fruitful for cross-national comparisons of privatization programs because it is at this level that privatization strategies are designed. The problem for Eastern Europe and for less-developed countries is lack of experience with the relatively light economic regulation that characterizes industrial countries. Government leaders must also decide how much effort to devote to privatization of state-owned enterprises and how much to fostering private sector investment in new firms. Ernest J.

This article considers how India sees the Indian Ocean, and in particular its drive to make the Indian Ocean, “India's Ocean.” Various comparisons and links are made. Firstly there is the role and application of Mahanian tenets of “sea-power,” in particular naval projection, control of sea-routes and access to bases. Second is the contrast between the earlier maritime visions of Kavalam Panikkar (1945) and Keshav Vaidya (1949) and the continental mindset evident under Nehru and his successors which saw neglect of India's maritime power. Third is the strategic vision evident since 1998 with the BJP government and maintained by the Congress administration since 2004. This has underpinned India's Naval Chief of Staff Arun Prakash's current eloquence on the possibilities opening up for India in and around the Indian Ocean. Questions of intent (strategic doctrine) and the application of “state power” (spending, bases, ships and equipment, geographical reach) are woven together.  相似文献

In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here.  相似文献

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept® oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept® enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall ‘present’/‘not found’ reports calculated as true positives/(true positives + false negatives) were for the amfetamine specific assay 50%, methyl-amfetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.  相似文献

Two conditions must be met in order for a person to be rightly considered the victim of a crime. First, there must be the victim of some form of harm. Second, the harm in question was the direct result of an act in which the harmed individual did not knowingly consent to take part. What are the dynamics of consent and how important should consent be in defining and placing criminal responsibility in crimes where women are sexually victimized? Finally, how does the conceptualization of victimization change when viewed from liberal and radical feminist perspectives?  相似文献

A decade of divorce mediation research has focused on outcomes such as settlement rates, cost efficiency, client satisfaction, effect on levels of conflict and cooperation, psychological adjustment, and compliance. Despite methodological problems limiting generalizations, most studies report mildly favorable to very positive findings. Research on the mediation process and mediator behaviors has received very limited attention, and should be the focus of the next decade of research to elevate the mediation field to a more sophisticated, effective level of practice.  相似文献
