Regulation increasingly mandates collaborative approaches to increase stakeholder input and streamline approval processes. However, understanding how to maintain stakeholder involvement over the course of a long collaborative process is vital to optimize effectiveness. This paper observes more than 700 stakeholders involved in developing and implementing a dam operating license over 16 years. We use text mining and Bayesian hierarchical modeling to observe meeting attendance and recorded actions in meeting minutes. We find that involvement decreased after the initial planning phase, but steadily increased through license development and implementation. After the regulatory mandate to consult with external stakeholders dissolved, overall attendance declined while attendance stability increased, meaning that the non‐mandatory stage involved a smaller cadre of dedicated actors. This indicates that high‐performing mandated stakeholder involvement processes rely on a constrained group of conveners to sustain interaction and have less turnover than what might be expected given existing evidence from grassroots involvement; assumptions about group dynamics based on involvement in grassroots processes may lead to improper predictions about who will participate, and how, in processes where stakeholder involvement is mandated.  相似文献

This paper discusses, with an emphasis on the technical issues involved, some of the possible forms that nuclear terrorism might take, loosely referring to all forms of terrorism involving radioactive materials, such as crude nuclear weapons, radiological dispersal devices, and attacks on the nuclear infrastructure, including nuclear reactors. The first two forms of terrorism necessarily depend on terrorists' obtaining suitable materials, so the problem of nuclear smuggling, especially from the former Soviet Union (FSU), with its huge and decrepit nuclear complex, is addressed, as is the region's reservoir of unemployed or underemployed nuclear expertise. The West, however, is not ignored. As one observer remarked, Osama bin Laden might soon have more luck shopping for nuclear materials there than in the FSU. The paper concludes that although it is most unlikely that terrorists will detonate a true nuclear weapon, the other forms are real and pressing threats.  相似文献

This article describes the author's experience of commisioned reseach, outlining its main findings and the response of the funding body to the final report. The research examined the effects of shiftwork on women. It was found that the sexual division of labour within the family in Britain makes it difficult for women to work certain hours, including the ‘normal’ full-time day hours, and so hours of work can discriminate against women with responsibility for young children. Protective legislation is not the cause of inequality in wages and affords some protection to women from certain hours of work in industries that are covered by these laws. Trade union attitudes and practices towards women at local level help to reinforce rather than transform the sexual divisions of labour within the workforce and within the family.The final report contained three pages specifically on trade unions and their attitude towards women and shiftwork. The trade union group at the evaluation colloquium demanded their exclusion from the final report, virtually accusing the researchers of fabrication.  相似文献

A retrospective suicide study revealed that the Forestry Commission car parks in the New Forest in southern England were a previously unrecognized magnet for nonlocal suicides, attracting as high a proportion of "visitors" (35/43 in 1993-97) as among suicides who jumped from the cliffs at the infamous Beachy Head (39/48 in 1993-97). Over 95% of the car park suicides died from car exhaust gas poisoning. A multiagency initiative aimed to reduce the number of suicides in the 140 New Forest car parks where restricting access was impossible, and environmental issues paramount. Signs displaying the Samaritans' national telephone number were erected in the 26 car parks in which 50% of the car park suicides had occurred. Numbers, location, and residence of all car park deaths were monitored for 3 years. Corresponding changes in other forest registration districts were also monitored. During the 3-year intervention period the number of car park suicides fell significantly from 10/year, 1988-1997, to 3.3/year. The average annual total number of suicides in the New Forest registration district also decreased. No significant changes were found in comparable forest districts. The number of suicides in the New Forest car parks remained low during the 2 years following the evaluation.  相似文献

The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl ammonium salt 2a. Furthermore, this was observed to undergo rearrangement during analysis using gas chromatography-mass spectrometry (GC-MS) with products including 3-(2-chloroethyl)indole 3 and 2-methyltetrahydro-beta-carboline 4 (2-Me-THBC). This study further investigates this so far unexplored area of solvent interactions by the exposure of DMT to other halogenated solvents including dibromomethane and 1,2-dichloroethane (DCE). The N-bromomethyl- and N-chloroethyl quaternary ammonium derivatives were subsequently characterised by ion trap GC-MS in electron and chemical ionisation tandem MS mode and by NMR spectroscopy. The DCE-derived derivative formed at least six rearrangement products in the total ion chromatogram. Identification of mass spectrometry generated by-products was verified by conventional or microwave-accelerated synthesis. The use of deuterated DCM and deuterated DMT 1b provided insights into the mechanism of the rearrangements. The presence of potentially characteristic marker molecules may allow the identification of solvents used during the manufacture of controlled substances, which is often neglected since these are considered inert.  相似文献

Drawing on the distinction between self‐rule and shared rule in multilevel states, this article argues that shared rule has been the neglected element of the UK devolution settlement. The ability of the devolved administrations to participate in, and influence, national decision making through shared rule mechanisms is very limited. The article argues that the lack of shared rule is especially problematic in light of the increasing complexity of the Scottish devolution settlement in the wake of the Scotland Act 2012 and the Smith commission report. Smith, in particular, seems set to increase both the power of the Scottish Parliament and its dependence on UK policy decisions in the areas of tax, welfare and the economy. Creating a more robust intergovernmental system which could manage these new interdependencies will be a significant challenge, and yet, without such a system, the new settlement will be difficult to sustain.  相似文献
