STATE LEGISLATIVE RESPONSE TO THE CENTRAL ARIZONA PROJECT1

This research deals with the manner in which the Arizona Legislature dealt with the issue of the Central Arizona Project. Due to the massive costs and impact, the Central Arizona Project was handled by the Legislature in a nonroutinized manner. There was no Legislative precedent for dealing with such a major public work project. Given the Legislature's annual program concerns and priorities, it is neither structurally nor psychologically geared to respond to the Central Arizona Project in terms of placing it within an agenda of priorities even for discussion.

Dilemmas of regional planning in Hungary

The author provides an account of Hungarian regional policy and planning during the last 40 years, describing a socialist state trying to escape from a centrally planned economy. The paper discusses the consequences of the reforms and the problems of conflict resolution which resulted. The author argues that central planning will continue to be necessary in the future, and that there is a need to strengthen the co‐ordinative role of regional plans.

典型装备温度响应测量及平衡时间研究

目的 研究武器装备在温度环境试验过程中温度的测量方法和温度平衡稳定的时间。方法 利用直接测量方法对3种典型装备进行温度响应时间测量和分析,找出不同类型装备的传热规律,明确其温度环境试验的作用机理,确定装备的温度平衡时间。结果 通过多项试验测试的数据分析了武器装备温度试验应力的选取,在低温和高温工作试验时,整体温度平衡所需时间应适当延长8～10h,高温贮存时间偏短,应适当延长4～6h。结论 在武器装备温度环境试验中,应根据自身性能特点获得装备的真实温度相应特性,在条件允许的情况下,尽可能地敞开武器装备的密闭空间,加快热交换,以缩短达到温度平衡的时间。对于关键及敏感部件,应实时进行温度响应测量,保证试验量级选取的科学合理,为装备环境分析及试验方案的制定提供参考依据。     

基于上限定理的抗滑群桩设计理论研究

针对抗滑群桩设计理论方面存在的问题,即荷载传递及滑坡推力分配的不确定性,基于极限分析的上限定理,给出了一种抗滑群桩的设计方法,即人为增大第一排抗滑桩的桩间距,并按极限土压力公式设计,作用在第二排抗滑桩上的荷载则按照上限定理给出。根据上述思想,并结合滑坡能量安全系数的定义和多块体体系速度场计算方法,提出了抗滑群桩的一种设计理论。     

Evaluation of Maryland's state police impaired driving reduction effort (SPIDRE)

Objective: Alcohol-impaired driving is a significant factor in fatal and serious injury-producing crashes in the United States and many other countries. In 2013, the State of Maryland implemented an anti-driving under the influence (DUI) enforcement program, called the State Police Impaired Driving Reduction Effort (SPIDRE). This enforcement effort consisted of a select team of 7 police officers from the Maryland State Police who engaged in high-intensity driving under the influence (DUI) enforcement. The purpose of this evaluation was to determine the impact of the SPIDRE program on impaired-driving crashes, DUI arrests, DUI adjudicative outcomes, and public perceptions of DUI enforcement.

Methods: Data from alcohol-related crashes, arrests, and adjudicative outcomes of those arrests were used, along with data obtained from public opinion and bar patron surveys, to compare counties where the SPIDRE program operated and non-SPIDRE counties where it did not. The evaluation period extended from 2010 to 2016 in monthly intervals. Autoregressive integrated moving average (ARIMA) methods were used for the data analyses of crashes and arrests.

Results: There was no significant reduction in alcohol-related crashes as reported by the police associated with the SPIDRE program. However, there was a statistically significant decrease in the ratio of single-vehicle nighttime to multiple-vehicle daytime crashes in the SPIDRE counties but not in any other counties, suggesting a positive effect using this surrogate measure of impaired-driving crashes. The specific comparison counties as well as the other non-SPIDRE counties in Maryland experienced a statistically significant decrease in DUI arrests during the evaluation period, whereas the SPIDRE counties did not show such a decrease. Further, the arrests made by the SPIDRE team resulted in a significantly higher rate of positive adjudicative outcomes than arrests made by non-SPIDRE officers in those counties where the SPIDRE team operated. There was no evidence that the public was more aware of DUI enforcement efforts in the SPIDRE counties than in the non-SPIDRE counties.

Conclusions: The SPIDRE program appeared able to prevent a downward trend in DUI arrests, experienced by the rest of the state, and achieved higher quality arrests resulting in more positive adjudicative outcomes. The way in which the SPIDRE team was deployed may have lacked sufficient duration and intensity (e.g., only 2–3 months of activity in any given county) to achieve a reduction in alcohol-impaired-driving crashes as reported by the police. It is recommended that the SPIDRE team increase its enforcement activities for at least 9–12 consecutive months in the county where they are employed.
