Local authorities in the UK have come under renewed pressure from central government both to adopt Local Agenda 21 and to advance participative democracy. In late 1996/early 1997, the (then) new unitary authority of Bath and North‐East Somerset Council set up a Local Agenda 21 Issue Commission to review its ‘sustainability’ performance and policy development practice with the direct involvement of the community. The way in which the commission was conceived and conducted resulted in difficulties in identifying and carrying out its task. Nonetheless, it kick‐started significant steps towards LA 21 within the council, and provided valuable insights into LA 21 implementation, and the nature of meaningful consultation.  相似文献

Since its “depenalization” in 1993, the U.S. dollar has become possibly a more significant component of Cuba's money supply than the old peso. What are the alternatives? The euro seems inappropriate, given the inevitability of eventual normalization of relations with the United States. More advantageous would be to restore the Cuban peso, though this would involve unifying the bifurcated economic structure and the dual monetary and exchange rate systems. The Cuban government has yet to announce its plans. This study argues that an appropriate mix of exchange rate, monetary, fiscal, and income or wage and salary policies should support a rehabilitation of the Cuban peso.  相似文献

The United States of America would seem to be an excellent location for using pollen data in forensic applications. The vegetation within the region is highly diverse ranging from areas of Arctic tundra to some of the most inhospitable deserts anywhere in the Western Hemisphere. The highly varied ecology, great plant diversity, thousands of vegetational microhabitats, and extensive published pollen records for the region provide an ideal setting for these types of analyses. This diversity, often characterized in most locations by unique combinations of pollen types, makes the use of forensic pollen a reliable technique that can often be used to associate individuals with a unique crime scene or geographical region. Nevertheless, forensic pollen studies in the United States of America are currently one of the most highly under utilized techniques available to assist in solving criminal and civil cases. During the past century there has been a very limited attempt to use pollen evidence in either criminal or civil cases, for a variety of reasons, including a lack of available information about the technique, a very limited number of specialists trained to do forensic pollen work, and an almost total absence of academic centers able to train needed specialists or forensic facilities able, or willing, to fund research in this area. Hopefully, this paucity of use will change if certain steps are taken to encourage the routine collection and use of pollen evidence in both criminal and civil cases.  相似文献

This paper presents a geometrical model for the ricochet of shotgun pellets from an intermediate target surface. The model predicts that after ricochet the shotgun pellet pattern will be elongated in the direction parallel to the intermediate target surface, as has been found in empirical studies. This paper also shows that the angle of impact theta of a mass of shotgun pellets with a target surface can be calculated without significant error from the width W and the length L of the pellet pattern using the formula: sin theta= W/L.  相似文献

This article shows that highly correlated measures can producedifferent results. We identify a democratization model fromthe literature and test it in more than 120 countries from 1951to 1992. Then, we check whether the results are robust regardingmeasures of democracy, time periods, and levels of development.The findings show that measures do matter: Whereas some of thefindings are robust, most of them are not. This explains, inpart, why the debates on democracy have continued rather thanbeen resolved. More important, it underscores the need for morecareful use of measures and further testing to increase confidencein the findings. Scholars in comparative politics are drawnincreasingly to large-N statistical analyses, often using datasets collected by others. As in any field, we show how theymust be careful in choosing the most appropriate measures fortheir studies, without assuming that any correlated measurewill do.  相似文献

Modeling the heterogeneous trajectories along which antisocial behaviordevelops in childhood and adolescence may contribute in important waysto understanding antecedents of offending in adult life. This paperexamines the development of aggressive and non-aggressive conduct problemsin the Great Smoky Mountains Study of Youth, a longitudinal study in thesoutheastern United States. Aggressive and non-aggressive conduct problemsof clinical severity, police contact and arrest, and family andenvironmental correlates were assessed in four annual interviews for789 boys and 630 girls aged 9–13 at first interview. The bestfitting latent class model identified three developmental trajectories:stable low problem levels, stable high problem levels, and declining levelsof conduct problems, for both aggressive and non-aggressive behaviors. Boyswere over-represented in the stable high trajectory class on the aggressivetrajectory, but sex differences in non-aggressive trajectories were lessmarked. The overlap between aggressive and non-aggressive trajectory classeswas quite limited. Both classifications showed strong associations withrisks of police contact and arrest in early adolescence, and with measuresof family adversity. The results are discussed in relation to developmentalmodels of conduct disorder and delinquency.  相似文献

This study examines type-specific and cumulative experiences of violence among a vulnerable population of youth. Sixty high-risk, shelter-dwelling, urban youth were interviewed regarding their history of childhood maltreatment, exposure to community violence (ECV), and experience with intimate partner violence (IPV). Results show a high prevalence and high degree of overlap among multiple types of violence exposure. Childhood physical, sexual (CSA), and emotional (CEA) abuse were interrelated and were associated with ECV. Cumulative experiences of childhood abuse (CCA) had a graded association with IPV victimization. In multivariate analyses, CCA and ECV were independently associated with IPV victimization. Gender moderated the effect of one association: CEA raised the risk of IPV victimization for girls but not for boys. Only CSA predicted IPV perpetration. Findings suggest that cumulative exposures to violence create cumulative risk for experiencing more violence. Shelter-dwelling, urban youth may be particularly vulnerable to this additive effect.  相似文献
