Does lawmaker behavior influence electoral outcomes? Observational studies cannot elucidate the effect of legislative proposals on electoral outcomes, since effects are confounded by unobserved differences in legislative and political skill. We take advantage of a unique natural experiment in the Canadian House of Commons that allows us to estimate how proposing legislation affects election outcomes. The right of noncabinet members to propose legislation is assigned by lottery. Comparing outcomes between those who were granted the right to propose and those who were not, we show that incumbents of the governing party enjoy a 2.7 percentage point bonus in vote total in the election following their winning the right to introduce a single piece of legislation, which translates to a 7% increase in the probability of winning. The causal effect results from higher likeability among constituents. These results demonstrate experimentally that what politicians do as lawmakers has a causal effect on electoral outcomes.  相似文献

Civic-republican theories suggest that an active citizenry is associated with community cohesion, better political institutions and inclusive democratic decision making. The influence of these arguments on the UK Labour government has led policy makers to focus attention on strategies to promote citizenship at a local level. In particular, English local authorities are expected to provide ‘support for citizenship’ as part of their wider duty to promote ‘effective community engagement’. The ways in which they can do this are various, ranging from the simple provision of information to direct support for community networks and groups. This article reports the findings of an extensive study of English councils' efforts to engage, educate and empower local citizens. The paper concludes that although local authorities have made significant progress in recent years in widening the structures for communicating with, and engaging citizens, there remains considerable scope for improving activities that address the learning implications of effective citizenship.  相似文献

Decision-makers and affected parties engaged in solving contemporary governmental problems are recognizing that traditional decision-making strategies are insufficient. A participatory democracy approach to public participation has been offered as a potential solution to these problems; however, a more sophisticated understanding of this approach is needed. This study defines a more substantive brand of public participation, identifies barriers to its implementation, and provides recommendations for implementation. Models of substantive participation should empower and educate all stakeholders, reeducate public administrators, and establish new administrative structures and processes. These objectives as well as a discussion of particular barriers to substantive participation are outlined.  相似文献

Abstract

Two of Michael Mann's recent books continue his exploration of the sources of social power and then extend it into the study of ethnic cleansing, a phenomenon which Mann wishes to see as a potential built into modern political institutions, and specifically democratic political cultures, from the start. However, this review argues that the richness of the empirical material mobilized in these books makes them more nuanced and sophisticated than Mann's own summary of them suggests.  相似文献

Wrestling Sprawl to the Ground: Defining and measuring an elusive concept   总被引:5,自引:0,他引:5  
Abstract

The literature on urban sprawl confuses causes, consequences, and conditions. This article presents a conceptual definition of sprawl based on eight distinct dimensions of land use patterns: density, continuity, concentration, clustering, centrality, nuclearity mixed uses, and proximity. Sprawl is defined as a condition of land use that is represented by low values on one or more of these dimensions.

Each dimension is operationally defined and tested in 13 urbanized areas. Results for six dimensions are reported for each area, and an initial comparison of the extent of sprawl in the 13 areas is provided. The test confirms the utility of the approach and suggests that a clearer conceptual and operational definition can facilitate research on the causes and consequences of sprawl.  相似文献

The regular article tracking developments at the national level in key European countries in the area of IT and communications – co-ordinated by Herbert Smith LLP and contributed by firms across Europe. This column provides a concise alerting service of important national developments in key European countries. Part of its purpose is to complement the Journal's feature articles and briefing notes by keeping readers abreast of what is currently happening “on the ground” at a national level in implementing EU level legislation and international conventions and treaties. Where an item of European National News is of particular significance, CLSR may also cover it in more detail in the current or a subsequent edition.  相似文献

Fingermarks are a key form of physical evidence for identifying persons of interest and linking them to the scene of a crime. Visualising latent (hidden) fingermarks can be difficult and the correct choice of techniques is essential to develop and preserve any fingermarks or other (e.g. DNA) evidence that might be present. Metal surfaces (stainless steel in particular) have proven to be challenging substrates from which to reliably obtain fingermarks. This is a great cause for concern among police forces around the globe as many of the firearms, knives and other metal weapons used in violent crime are potentially valuable sources of fingermark evidence. In this study, a highly sensitive and non-destructive surface science technique called time of flight secondary ion mass spectroscopy (ToF-SIMS) was used to image fingermarks on metal surfaces. This technique was compared to a conventional superglue based fuming technique that was accompanied by a series of contrast enhancing dyes (basic yellow 40 (BY40), crystal violet (CV) and sudan black (SB)) on three different metal surfaces. The conventional techniques showed little to no evidence of fingermarks being present on the metal surfaces after a few days. However, ToF-SIMS revealed fingermarks on the same and similar substrates with an exceptional level of detail. The ToF-SIMS images demonstrated clear ridge definition as well as detail about sweat pore position and shape. All structures were found to persist for over 26?days after deposition when the samples were stored under ambient conditions.  相似文献

This article examines developmental trends in the rates of different kinds of victimization across the span of childhood. The Developmental Victimization Survey was a national telephone survey of the victimization experiences of 2,030 children from ages 2 to 17. The overall mean number of victimizations during a single year increased with age, as did the percentage of children with polyvictimizations (4 or more different kinds of victimization). However, some specific types of victimization, physical bullying and sibling assaults, were highest prior to adolescence and then declined. Other types had different developmental patterns by gender. Peer assaults increased in adolescence for boys but not for girls. Child maltreatment and sexual victimization increased in adolescence for girls but not for boys. The complex and diverse patterns of developmental vulnerability to different kinds of victimization at different ages need more exploration and explanation in order to better target prevention and intervention policies.  相似文献
