The Colorado,USA, Joint Review Process: an initial evaluation of its success as a permit reform by key participants

Colorado, USA, developed the Joint Review Process (CJRP) in 1978 to coordinate the application and review of permits required for major development projects. Since then, the state has used the process on over 20 projects. This study examined whether the CJRP has achieved its primary goals—enhanced coordination of agencies, enhanced public participation, and strengthened communication between agencies and project sponsors— and several related secondary goals. The success of the process was measured through a survey of 54 key people who had been directly involved with the process. Those surveyed included federal and state agency staff, local agency managers, corporate officers, private consultants, and environmental leaders. All groups, with one exception, agreed that the process achieved its primary goals and that it should be retained. Environmental leaders were neutral about whether the process enhanced public participation and about retaining the process. The report concludes with a review of recommended improvements to and applications of the CJRP.

中国山区沟谷泥石流危险度的定量判定法

本文根据专家系统调查,确定了一次泥石流冲出物最大方量和泥石流暴发频率作为判定泥石流危险度的主要危险因子。运用灰色关联度分析,优选出10项判定泥石流危险度的次要危险因子,并根据关联序确定了它们的权重。在各危险因子等级划分的基础上,得出了泥石流危险度的定量计算公式。通过实例检验,证明该判定方法具有60％以上的可靠度。     

火灾后钢筋混凝土损伤程度的灰关联分析

由于火灾对钢筋混凝土结构的影响存在不确定性,使得人们不能准确地确定火灾后钢筋混凝土结构的损伤程度,给评估和加固修复带来很大困难。本文运用灰色系统理论中灰关联分析数学模型定量分析了高温下钢筋混凝土梁的3种影响因素,并确定了各因素间的主次关系,为高温后钢筋混凝土结构的安全评估及修复加固提供了理论依据。     

可拓法评估煤矿瓦斯爆炸易发性

为了量化煤矿瓦斯爆炸的可能性,并为防治瓦斯爆炸提供量化指标,借鉴可拓学原理,对煤矿瓦斯爆炸易发性进行预评估。首先,详细阐述可拓学评估原理;接着,为了验证煤矿瓦斯爆炸易发性可拓评估的可行性,结合某一煤矿实例,比选煤矿瓦斯爆炸易发性的评价指标,并确定煤矿瓦斯爆炸易发性的分类标准,构建煤矿瓦斯爆炸易发性评估的经典域、节域和物元;然后,为了避免确定指标权重的人为主观因素的影响,提出用简单关联函数确定指标权重;最后,计算煤矿瓦斯爆炸易发性的关联函数值和关联度,确定瓦斯爆炸易发性的等级及其变量特征值。经计算,煤矿爆炸易发性的可拓评估结果为"很小"等级。同时,为了验证可拓评估结果的合理性,将其与模糊评估进行比较,两者所得评估结果相一致。从而表明:将可拓学应用于煤矿瓦斯爆炸易发性评估是合理可行的。

A Spatial equilibrium perspective for planning the production of electrical energy

A spatial and temporal equilibrium model of production, consumption, prices, and transmission is constructed to determine the efficient pricing and allocation of electrical energy in the United States. Regional coordination is technically feasible and economically attractive. It also maximizes environmental efficiencies. The duplication of electrical generation and transmission facilities yields a misallocation of resources.The utilities put forth specific arguments against coordinated operations. Yet in a fully integrated power system, each region would be expected to maximize the benefits of time diversity by purchasing from outside the region in lieu of the expansion of regional capacity. The Federal Energy Regulatory Commission has not yet made a serious move to encourage regional coordination and planning, but the Commission has the authority to promote such operations if it chooses to do so.The author is an economist with the Department of Energy. The views expressed are those of the author and do not necessarily represent the policies of the Department of Energy or the views of other staff members.     

The impact of team familiarity and team leader experience on team coordination errors: A panel analysis of professional basketball teams

To explore the dynamics involved in team coordination, we examine the impact of team familiarity and team leader experience on team coordination errors (TCEs). We argue that team familiarity has a U‐shaped effect on TCEs. We study the moderating effects of team leader prior experience and team leader team‐specific experience on the association between team familiarity and TCEs. We use panel data on teams from the National Basketball Association to test the hypotheses. Our findings support the U‐shaped relationship between team familiarity and TCEs and the moderating effect of team leader team‐specific experience on this relationship. The paper advances research on errors in organizations by analyzing the antecedents of TCEs, so far an underexplored empirical phenomenon. Moreover, it contributes to research on coordination in teams by empirically examining the interplay between formal and informal coordination mechanisms.

基于灰色模糊集理论的船舶搁浅概率分析

为深入分析船舶搁浅概率,在随机性和模糊性的基础上,考虑了系统的灰色性,建立灰色模糊集,模部为正态模糊数,灰部以系统的灰度熵来表示。建立了船舶航行计划失效造成船舶搁浅的事件树,构造了船舶搁浅概率的灰色模糊隶属度函数,根据各基本事件的失效概率来分析因航行计划失效造成船舶搁浅事故的灰色模糊概率分布情况。结果表明,与经典概率论和模糊概率相比,采用灰色模糊概率更能全面地反映船舶搁浅概率的可能性与不确定性。并采用RRW法和RAW法对基本事件的重要度进行了分析,找出了事故主要诱因及对降低事故风险价值最大的基本事件。
