Production frontiers with technical inefficiency determinants are estimated using stochastic models for textile manufacturing in eight developing countries encompassing about 800 firms. Inefficiency determinants are considered either on an individual basis, or in the form of composite indicators reflecting in-house or managerial factors and various dimensions of the external environment. Although each of these two categories of factors is statistically significant, the former proves more influential in the explanation of the difference in efficiency between firms. Simulations are then proposed to assess the efficiency levels that would occur if firms had the opportunity to produce in the most favourable productive environments. 相似文献

Identification of an unknown body and prediction of growth from specific body measurements are very important tasks in the fields of physical anthropology and forensic medicine. Height and weight are two factors among others required to establish individuality of an unidentified body. In the present work, an attempt has been made to calculate the stature and weight from percutaneous tibial length and bimalleolar breadth. The study was carried out on 1000 living Egyptian individuals comprising 500 males and 500 females; their age was between 19 and 21 years. A significant positive correlation between stature and tibial length in both sexes was recorded. The coefficient of determination showed that 56% of variation in stature was due to tibial length and bimalleolar breadth in males, while in females the coefficient of determination was 23%. On the other hand, the coefficient of determination for weight showed that 11% of variability in weight was due to tibial length and bimalleolar breadth in males, while in females it was 5%. Linear regression analysis was done for all variables in all cases. The regression equation formulae are helpful in the estimation of stature and weight of the deceased from tibial length and bimalleolar breadth when leg or foot is the only portion available for autopsy examination. 相似文献

The International Criminal Court (ICC) has already issued itsfirst arrest warrants. Hence, the question of the custodialstate arresting a person in response to a request issued bythe Court and his or her appearance before competent judicialauthorities (per Article 59(2) ICCSt.), becomes compelling.Several pertinent questions arise in relation to the applicationof this provision. The article addresses, in particular, issuessuch as: (i) the rationale for Article 59; (ii) the implicationsof paragraph 2; (iii) the consequences of non compliance withthis provision; (iv) the impact of human rights decisions onits application and (v) the question of self-referrals in relationto paragraph 2. 相似文献

Occupational exposure biological monitoring techniques were applied for the diagnosis of inhalation abuse and for the evaluation of the levels of exposure to benzene, toluene, ethylbenzene, xylenes, and n-hexane, in 44 Tunisian adolescents and children suspected for volatile substance addiction. Urinary trans,trans-muconic acid, hippuric acid (HA), mandelic acid, and methylhippuric acids determinations were performed by high performance liquid chromatography with a photodiode array detector, and urinary o-cresol (o-Cr) and 2,5-hexanedione (HD) were extracted simultaneously and measured using gas chromatography with a flame ionization detector. Given the high linearity ranges, HD and o-Cr occupational exposure monitoring techniques could be applied without modification. However, urinary sample dilution was necessary before HA analysis. Concentrations were compared with the maxima of normal values (MNVs) in the general population and to the biological exposure indices (BEIs) used in occupational toxicology. Values as high as 6610-fold the MNV and 68 times the BEI were registered. The subjects showed high exposure to toluene and hexane. Measured metabolites HA and/or o-Cr and HD enabled the easy detection and evaluation of exposure levels. The problem of inhalant abuse should be given more attention and treated through an effective prevention strategy. 相似文献

The purpose of this study is to analyze the ongoing conflict situation between the government of Pakistan and the tribal population groups residing in the tribal belt along the Pakistan–Afghanistan border, while Pakistan aids the United States in its “War on Terror.” The article brings into limelight the political problems being faced by the government of Pakistan while it supports the United States and its allies in their mission to combat and weaken the Al Qaeda and Taliban forces. It further attempts to apply some simple game theoretic models to the situation in Waziristan and tries to accommodate the influence of the third party (the United States in this case) on the strategies as well as on the Nash equilibrium of the players in this situation of conflict. The aim of this exercise is to capture and highlight policy insights that might emerge from this strategic analysis. The possible Nash equilibrium depicts that the presence of the third party in the said conflict complicates the situation in an adverse manner. Moreover, the rebels might find it profitable to rebel and retaliate against the government in the subsequent periods due to the grievances caused by the actions of government in the first period. The government of Pakistan therefore seriously needs to rethink and reform its strategy for dealing with the extremists in the case discussed. 相似文献

Little is known about the relationship between land use regulations and profits from subdivision development. Using data from a heavily regulated market, this article presents analyses that for the first time determine actual profits from subdivision development. This study found an average profit, measured by internal rates of return, of 29%, which is statistically greater than what scholars consider normal. Profits decreased as time to complete the subdivision increased. Profits also decreased because of delays due to regulations and voluntary decisions by developers. The findings suggest that higher profits could be attainable in more-regulated areas because regulations may create amenities whose value exceeds the costs of providing them, while the same regulations may make it difficult for outside developers to enter the market thus limiting competition among developers. The findings suggest that policy makers should be cautious about regulations that create amenities when these regulations may inhibit competition among developers. 相似文献
