In Nepal, which consists of ecologically distinct regions, the concentration of the adoption of modern rice varieties in the favourable rice growing areas of the country has raised fears that regional income disparities have widened. This study shows that greater demand for hired labour due to the adoption of modern rice varieties has induced permanent and seasonal migration from unfavourable to favourable areas. This appears to have largely equalised average wage rates across different production environments. Thus, as far as labour income is concerned, benefits from the modern varieties have been widely shared. 相似文献

Estimating the Number of Crimes Averted by Incapacitation: An Information Theoretic Approach 总被引:1,自引:1,他引:0
Avinash Singh Bhati 《Journal of Quantitative Criminology》2007,23(4):355-375
This paper presents an information theoretic approach for estimating the number of crimes averted by incapacitation. It first
develops models of the criminal history accumulation process of a sample of prison releasees using their official recorded
arrest histories prior to incarceration. The models yield individual offending trajectories that are then used to compute
the number of crimes these releasees could reasonably have been expected to commit had they not been incarcerated—the counterfactual
of interest. The models also afford the opportunity to conduct a limited set of policy simulations. The data reveal a fair
amount of variation among individuals both in terms of the number of crimes averted by their incarceration and the responsiveness
of these estimates to longer incarceration terms. Estimates were found not to vary substantially across demographic groups
defined by offender race, gender, or ethnicity; variations across states and offense types were more pronounced. Implications
of the findings and promising avenues for future research are discussed.

In a recent article Jürgen Habermas (1999) highlighted the potential for the European Union to act as a vehicle for the extension of democratic governance beyond the nation state, a project aimed at limiting the socially corrosive impact of globalisation. Yet this position appears paradoxical as the European Union itself exacerbates a major aspect of globalisation: the emasculation of national parliaments known as the 'democratic deficit'. This paradox can be understood by analysing the dynamics of post-war European integration through the lens of Habermasian social theory: EU evolution can lead either to the colonisation of the lifeworld by market and administrative subsystems (as with the democratic deficit), or to a process of lifeworld rationalisation conducive to pan-European solidarity and democracy. The latter of these tendencies could be encouraged through 'procedural democracy': this would institutionalise the conditions by which independent associations in European civil society, channelling their 'communicative power' through parliament, might reassert control over the two subsystems. In order to retain legitimacy, procedural EU democracy would have to link existing legislatures to the European Parliament, while citizenship would combine national and civic components. Hence the European Union would be more able than the nation-state to combine universal notions of justice with ethical pluralism. 相似文献

Postmortem stability of cyanide biomarkers is often disputed. We assessed the time and temperature-dependent changes in cytochrome c oxidase (CCO) activity and cyanide concentration in various organs of mice succumbing to cyanide. Immediately after death, excised mice organs and mice cadavers were stored at room temperature (35°C ± 5°C) or in frozen storage (−20°C ± 2°C). At various times after death, CCO activity and cyanide concentrations were measured in excised mice organs or organs removed from mice cadavers. The study revealed that (i) measuring both the biomarkers in mice cadavers was more reliable compared to excised mice organs, (ii) measuring temporal CCO activity and cyanide concentration in vital organs from mice cadavers (room temperature) was reliable up to 24 h, and (iii) CCO activity in the brain and lungs and cyanide concentration in organs from mice cadavers (frozen) were measurable beyond 21 days. This study will be helpful in postmortem determination of cyanide poisoning. 相似文献

The author expresses appreciation to G.S. Gupta and Andy K.M. Li for their valuable assistance in data processing and computer programming, and to Professor Tullock for his so thoughtful and constructive comments and suggestions which were extremely helpful in revising the original paper. The usual caveat applies. 相似文献

This article examines how events unfolded in the aftermath of the deaths of American servicemembers in Niger in 2017. It shows that there was remarkably little casualty aversion on the part of either the American public or the elites and examines why U.S. military policy towards Africa is so resistant to change, even when circumstances appear propitious. 相似文献

Sex identification is an initial crucial objective in the revelation of the complete identity of the human skeleton as it also renders significantly clearer guidance towards age and stature estimation. Population specific standards are of great practical relevance in the present era of increasing population intermixing. Size differences and robusticity are the two well-elaborated pillars holding most of the dimorphic burdens of the skull. This study is designed to explore dimorphic characteristics of the craniofacial region to establish anthropometric standards for contemporary North Indian populations, which have not been available so far. One hundred and twelve adult crania of known age (23-65 years) and sex (M:F; 82:30) were collected in the Department of Forensic Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. Ten standard metric parameters of craniofacial region were measured and subjected to stepwise and direct discriminant function analysis employing SPSS 16.00. Bizygomatic breadth emerged as the single best parameter in stepwise analysis, providing an average accuracy of 85.5%. 相似文献
