Local government reforms in contemporary Russia are placed in the broader contexts of political reform under Putin and the historical relationship between local administration and the state. Reforms of local government thus help illuminate the architecture of contemporary state building in Russia and the degree to which contemporary Russia perpetuates political traditions. This study reviews the antecedent action in local government prior to the Putin era. It then examines the Kozak Commission and the new law on local government, assessing the strengths and weaknesses of these reforms. Finally, this study examines the challenges of implementing the reforms and what these challenges tell us about devolution and centralisation under Putin.  相似文献

This study examines changes in the rate of offending in a sample of 8,834 males whose official juvenile law-violating careers included 26,650 offense episodes between ages 8 and 17 The rate of offending of active offenders (i.e., lambda) varied substantially as a function of age, increasing monotonically with age. Lambda, however, was not related to the age at first offense. In fact, the average lambda was amazingly constant at each individual age level regardless of the age at which offending began or desisted. Results are discussed in the light of age-crime curves known from other data sets and from the perspective of developmental changes in the rate of offending as youths grow older.  相似文献

In this paper we examine one of the areas where there is a marked difference between Civil and Common contract law, that of the enforcement of liquidated damages and more particularly of penalty clauses. Common law judges are quite reluctant to enforce liquidated damages, especially if they believe that they include penalty clauses which are not enforceable. On the contrary, in almost all European contract laws liquidated damages are readily enforced, as are penalty clauses when they are not manifestly excessive. Although most law and economics scholars have criticized Common law courts for the non-enforcement of penalty clauses, there is a sizable minority of scholars who have defended the Common law “non-enforcement” policy on the ground that penalty clauses are inefficient because they hinder efficient breach. However, and despite the merits of the arguments advanced by advocates of the non-enforcement of penalty clauses, we believe that Common law’s rejection of penalty clauses is inefficient. We further show that the Civil law solution to the problem is not only comparatively more efficient, but that it can also appease the worries of those scholars who are afraid that efficient breaches will be deterred. The solution that Civil law systems give to the problem manages to enforce the parties’ wishes and to avoid deterring efficient breaches. However, we point out that in order for the Civil law systems to take advantage of this superiority, the interpretation of their Civil Codes should be guided by economic analysis and the respect to the wishes of the contracting parties.  相似文献

Although law enforcement agencies across the nation have assumed part of the responsibility in the fight against terrorism, significant confusion exists as to the role of local law enforcement. While some agencies have taken steps towards terrorism prevention, little data has been collected on which agencies have taken the greatest steps, how those agencies have changed, and how other agencies should direct their activity. This case study of law enforcement census data from a single state considered variations in terrorism preparedness and predictors of preparedness. Agency size, presence of funding, and other variables significantly predict levels of terrorism preparedness. Important policy implications such as the distribution of funding and which agencies should be working towards terrorism preparedness are discussed.  相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.  相似文献
