Dozens of countries have decentralized at least part of their natural resource policies over the last two decades. Despite the length of time that these policy experiments have been in force, there is little agreement about their effectiveness. We argue that part of this ambivalence stems from three limitations of extant studies, suggesting that future studies of decentralized natural resource governance should consider a combination of 1) variation in the local institutional context, 2) the fit between the reform and other public policies, and 3) more adequate outcome measures for decentralized resource governance. After developing such an approach, we posit that varying forest conditions depend on the moderating effects that local institutions have on the socioeconomic and biophysical drivers of environmental change. Analyzing data from interviews and remotely sensed images from 30 municipalities in the Bolivian lowlands, we find that the local institutional performance affects unauthorized deforestation directly and indirectly, but detect no effects on either permitted or total deforestation. © 2006 by the Association for Public Policy Analysis and Management.  相似文献

Changes in government policy over the last two decades have seen the traditional goals of criminal justice, namely prosecution and punishment, being replaced by an emphasis on prevention, fear reduction, security and harm reduction. During this time domestic abuse has gained a place on the political agenda, which has resulted in legislative initiatives in the form of civil protection orders across the U.K. which primarily focus on prevention but have also more recently begun to rely on the traditional criminal justice responses should they fail to prevent further abuse. Drawing on international evaluations and a recent study conducted in Scotland (the Scottish study), the article examines whether legislation in the form of civil protection orders has the effect of curtailing the actions of abusers and if not, what occurs when the traditional criminal justice response comes into play. The strengths of civil protection orders and some explanations for the weaknesses of these orders are considered alongside the question of whether there is any value in women continuing to engage with the law in response to domestic abuse.

The Gene Print PowerPlex 1.1/Amelogenin and FFFL Fluorescent STR Systems have been validated following the recommendations presented by the Technical Working Group on DNA Analysis Methods (TWGDAM). The PowerPlex 1.1/Amelogenin System supports simultaneous amplification of eight short tandem repeat loci and the Amelogenin gender identification marker. The loci D16S539, D7S820, D13S317, and D5S818 are labeled with fluorescein (FL) while the loci CSF1PO, TP0X, TH01, vWA and Amelogenin are labeled with carboxy-tetramethylrhodamine (TMR). The FFFL Multiplex System is composed of the loci F13A01, FESFPS, F13B, and LPL, each labeled with fluorescein. We have observed no overlap of alleles across loci labeled with an individual fluorescent dye. Samples of each system were amplified and labeled in a single reaction, separated by electrophoresis through a denaturing polyacrylamide gel, and amplified alleles detected using a Hitachi FMBIO Fluorescent Scanner. Alterations from the standard amplification protocols in cycle number and annealing temperature generally produced excellent results. In experiments testing sensitivity as little as 0.2 ng of DNA template could be detected. As expected, different body fluids from the same individuals generated identical DNA profile results. Template DNA derived from blood-strains deposited on a variety of matrix supports displayed robust amplification except for material derived from deposits on wood and Japanese orchid leaves. Mixtures of DNA templates could be interpreted with the minor component present in as little as ten percent of the total sample. Monoplex and multiplex amplifications produced identical amplified allele patterns, indicating that STR multiplex systems save template and increase efficiency in the amplification procedure without loss of quality. Analyses of genotype frequencies in African-American, Caucasian-American and Hispanic-American populations using all twelve loci were used to determine matching probabilities smaller than 1 in 1.14 x 10(8) and 1 in 2658 for the PowerPlex 1.1 and the FFFL Multiplex Systems, respectively. The matching probability achieved with the two systems combined is smaller than 1 in 3.03 x 10(11). The independence of alleles within loci was generally demonstrated by applying the exact test to demonstrate Hardy-Weinberg Equilibrium. All of the studies performed indicate that the PowerPlex 1.1/Amelogenin and FFFL Multiplex Systems are powerful, robust, and reliable investigative tools that can be used in the analysis of forensic samples.  相似文献

A number of empirical models have found protection to be greatest for industries employing poorly skilled, low paid workers. This has caused some economists, notably Robert Baldwin, to suggest that equity concern by politicians in an alternative to the interest group hypothesis. This paper reports the result of a test on New Zealand data that shows that this equity concern is absent for industries with few employees or firms. Equity concern variables were only important for industries with many employees and firms. This suggests that equity concern is selective and may be reconcilable with self-interest motivations.I am grateful to John Tressler, Richard Harris and an anonymous referee for their helpful comments.  相似文献

This study examined the prevalence and correlates of sleep disturbance in adolescents. Two hundred seventy-seven 9th- and 10th-grade students completed a questionnaire on sleep quality, sleep habits, beliefs about sleep, and daytime mood and functioning. Based on their responses, subjects were classified as good sleepers (66%), occasional poor sleepers (23%), and chronic poor sleepers (11%). Occasional and chronic poor sleepers reported being significantly more depressed, without energy, tense, moody, and irritable and less rested and alert than good sleepers. They were also more likely to describe themselves negatively. However, poor sleepers were not consistently more tired than good sleepers. Rather, they tended to be least tired in the evening, the time when most good sleepers reported feeling tired. There were few differences in the sleep habits and beliefs about sleep of good and poor sleepers. All subjects reported shifts in bedtimes and waketimes from weekdays to weekends, with occasional and chronic poor sleepers showing a tendency toward greater shifts, a possible factor contributing to their sleep disturbance. Occasional and chronic poor sleepers also reported more observable behaviors and feelings of stress than good sleepers. The need for early intervention with particular attention to teaching adolescents about good sleep habits and the need for stable bedtimes and waketimes and the possibility of joint intervention on daytime stress and sleeping problems are discussed.  相似文献

During the 1950s, staff, students and graduates of Australian universities were increasingly critical of the racial restrictions on immigration, and their activism contributed to a broader government and community reassessment of the White Australia Policy. Personal experiences of cross‐cultural interactions between Australian students and an increasing number of international students from Asia, including those sponsored by the Australian government's Colombo Plan, underpinned the university challenge to immigration policy. Tertiary curriculum offering new academic interpretations of Asian history and decolonisation also contributed to a growing awareness among university‐educated Australians of Asia, and fostered empathy for its peoples. The publications of the Immigration Reform Group extended this critique of White Australia, and were driven by a moral indignation towards a policy that affected individuals personally known to the critics.  相似文献

In Canada's Yukon Territory, a legislative committee was tasked with assessing the risks and benefits of hydraulic fracturing. The committee designed an extensive participatory process involving citizens and experts; however, instead of information access and public hearings fostering an open dialogue and trust, these two channels failed to de‐polarize debates over hydraulic fracturing. We argue that mistrust was reinforced because (1) weak participatory processes undermined the goals of public involvement, (2) scientific evidence and scientists themselves were not accepted as neutral or apolitical, and (3) strategic fostering of mistrust by actors on both sides of a polarized issue intensified existing doubt about the integrity and credibility of the process. The implications of a failure to restore trust in government are significant, not only for the issue of hydraulic fracturing, but for governance more broadly, as mistrust has spillover effects for subsequent public negotiations.  相似文献
