In this article we explore how much state is necessary to make governance work. We begin by clarifying concepts of governance and the “shadow of hierarchy” and we follow this clarification with a brief overview of empirical findings on governance research in developed countries. We then discuss the dilemmas for governance in areas of limited statehood, where political institutions are too weak to hierarchically adopt and enforce collectively binding rules. While prospects for effective policymaking appear to be rather bleak in these areas, we argue that governance research has consistently overlooked the existence of functional equivalents to the shadow of hierarchy. We assert that governance with(out) government can work even in the absence of a strong shadow of hierarchy, we identify functional equivalents to the shadow of hierarchy, and we discuss to what extent they can help overcome issues of legitimacy and effectiveness in areas of limited statehood.  相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.  相似文献

An important national initiative in juvenile justice is Juvenile Offender Reentry (JOR). The renewed emphasis on offender reintegration has generated significant attention to juvenile justice practices, with the notable exception of juvenile confinement facilities. Juvenile detention and, to a lesser degree, juvenile corrections practitioners are involved but not invested in reentry, having made very few programmatic changes to accommodate JOR initiatives largely because these initiatives have been external to the institution and its staff. Yet, reentry is a powerful concept for juvenile facility practitioners, and the application of reentry principles could have a profound impact on daily operations. This article addresses a range of issues about investing juvenile institutions in reentry practices. Several reentry models are discussed along with their implications for daily operations and programs.  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

We discuss Professor Jeffrey Church's report to the EuropeanCommission in 2004 on the effects of vertical restraints andmergers. Although thorough and accurate, the report could bemisinterpreted by practitioners, as it does not emphasize thatmarket power is only a necessary condition for harm to competition,and that most vertical mergers that present the possibilityof competitive harm also present economic efficiencies thatare intrinsic to the integration.  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
