Short Reports

As the US population ages, more older adults will face transportation and mobility challenges. This study examines the characteristics and contributing circumstances of nonfatal older adult pedestrian injuries. Data were obtained from the National Electronic Injury Surveillance System-All Injury Programme (NEISS-AIP) for the years 2001 through 2006. Cases included persons aged 65 years and older who were nonfatally injured on a public roadway. The results indicated that on average, an estimated 52,482 older adults were treated in emergency departments each year for nonfatal pedestrian injuries. Falling and being hit by a motor vehicle were the leading mechanisms of injury, resulting in 77.5% and 15.0% of older adult pedestrian injuries, respectively. More than 9000 older pedestrian fall-related injuries each year involved a kerb. It is concluded that the growth in the older adult population could add to the overall burden of these nonfatal pedestrian injuries. Making transportation and mobility improvements, including environmental modifications, is important for preventing these injuries.     

The ‘Zest of Adventure’ in Australian Overland Narratives, 1920–2000

This paper is part of a broader research project which examines the history of leisure motor touring in Australia from the 1920s to 2004. At the core of this piece is an examination of the way adventure is presented in three non-fiction narratives that span 80 years. By considering different points in time the impact of the developing tourist infrastructure, improvements to roads and growing knowledge of the landscape, on the constructs of adventure can be seen. Yet, despite fundamental cultural shifts the lure and zest of adventure continued to function as a means of framing the overland experience. The narratives reveal the subjective nature of adventure and how it can be repackaged and re-presented at specific historical moments.

论机动车交通事故责任强制保险第三者的直接求偿权

在我国,机动车交通事故责任强制保险第三者是否享有直接求偿权的争议并未因《保险法》的修订而停止,本文从合同相对性理论的突破和责任保险理论基础的变化入手,分析了赋予第三者直接求偿权的现实意义,并从法理角度论证了该项权利的性质。最后,结合各国的立法现状,对我国现行相关立法和司法实践进行评析,同时提出相应对策和应注意的问题。     

电机绕组绕线机控制器的设计

随着机电产品对绕组质量要求的提高,原有的PLC控制系统的绕线机已很难满足不断发展的机电产品的要求。PLC控制系统的绕线机存在成本高,工作方式单一和人机交互不便等缺点。为解决此问题,我们设计了一种能代替PLC控制系统的新的控制系统--利用单片机进行控制的电机绕组绕线机控制器。     

A Multivariate Time‐Series Examination of Motor Carrier Safety Behaviors

Motor carriers’ operational safety affects multiple stakeholders including truck drivers, motor carriers, insurance companies, shippers, and the general public. In this article, I devise and test theory regarding motor carriers’ longitudinal performance for three classes of safety behaviors linked to carriers’ accident rates—Unsafe Driving, Hours‐of‐Service Compliance, and Vehicle Maintenance—tracked by the Federal Motor Carrier Safety Administration as part of the Compliance, Safety, and Accountability (CSA) program. Specifically, I draw on core concepts from sociological agency theory and resource dependency theory to devise middle‐range theory that generates never‐before‐tested hypotheses regarding carriers’ longitudinal safety performance for these classes of safety behaviors after the start of the CSA program. The hypothesized predictions are tested by fitting a series of multivariate latent curve models to four years of panel data for a random sample of 484 large, for‐hire motor carriers operating in the United States. The empirical findings corroborate the theoretical predictions and remain after robustness testing. These findings have important implications for scholars, motor carrier managers, procurers of motor carrier transportation services, and public policy makers.
