新《刑事诉讼法》特别程序对诉讼效率价值的坚持与完善

诉讼效率是《刑事诉讼法》应始终追求的重要价值,诉讼效率应当包括"效益"和"速率"两层含义。其中的效益是指通过诉讼程序办理的案件质量较高、结果合理,强调效益有利于司法工作、法律效果和社会效果的良好统一;而速率是指遵循诉讼程序使得刑事案件处理较快、过程迅速,强调速率有利于对司法资源的合理调配和充分利用。但效益和速率并不能完全地同步实现,任何诉讼程序都可能向其中一者倾斜而忽略另一者,尤其是忽略对效益的追求。同样地,新《刑事诉讼法》特别程序也应当尽力保持这两者间的平衡,通过一定制度设定弥补因速率带来的效益损失。     

道路交通事故速度重建技术现状

事故车辆行驶速度是道路交通事故调查的重要内容,也是公安交通管理部门进行事故认定,法院进行司法审判的关键技术依据。目前事故车辆行驶速度调查的主要途径是办案单位委托具有专业技术能力的司法鉴定机构进行速度重建,使用的方法主要有基于事故形态的速度重建、基于模拟软件的速度重建、基于车载记录数据的速度重建和基于视频图像的速度重建。通过从速度重建的技术发展、执业类别和能力验证等方面介绍了我国道路交通事故速度重建技术的发展现状。     

Determination of average vehicle speed utilizing reverse projection

Reverse projection photogrammetry has long been used to estimate the height of an individual in forensic video examinations. A natural extrapolation would be to apply the same technique on a video to estimate the speed of an object by determining the distance traveled between two points over a set amount of time. To test this theory, five digital video recorders (DVRs) were connected to a single fixed camera to record a vehicle traveling down a track. The vehicle's speed was measured through Doppler radar by a trained operator and the speedometer of the vehicle was also recorded with a video camera. The recorded video was examined and the frames that best depict the beginning and end of the vehicles course were selected. Two reverse projection photogrammetric examinations were performed on the selected frames to establish the position of the vehicle. The distance between the two points was measured, and the time elapsed between the two points was examined. The outcome provided an accurate speed result with a standard degree of uncertainty. This study proves the feasibility of using video data and reverse projection photogrammetry to determine the speed of a vehicle with a limited set of variables. Further research is needed to determine how additional variables would impact the standard degree of uncertainty.     

The sublime and the cultures of the extreme: An exploration

Abstract

The article traces the relationship between the concept of the traditional sublime and the contemporary cultures of the extreme and their fascination with unlimitation. It is asked to what degree the aesthetic category of the sublime, generally defined as a ‘formlessness’, can assist in exploring and making sense of the cultures of the extreme. The cultures of the extreme are analysed by means of three tropes, namely the ecstasy of speed, the immersion into immediacy, and the shrinking of the natural landscape. By utilising these three tropes or hermeneutical tools, the author attempts to show how these events typify the contemporary obsession with extremes, and can indeed be likened to a pseudo-sublime or kitsch sublime.     

高速公路限速问题研究——科学设置限速标志 创和谐高效高速公路

目前国内对于高速公路限速尚无系统的规定,高速公路上基本以设计速度作为限制速度,这存在着极大的弊端。而合理的限速值不仅能够平衡速度与安全的关系,也能提高道路的运输效率。本文从高速公路限速原则、限速值的考虑因数及具体实施限速方案等几个方面进行分析,这对进一步制定合理的高速公路限速对策有着重要的现实意义。     

数学学习困难儿童的认知加工机制研究

与数学学习优秀儿童相比,数学学习困难儿童的语音加工速度、短时记忆、中央执行功能以及整体工作记忆能力方面都存在明显不足,但只有工作记忆能力不足才能明确解释数学学习困难,即数学学习困难与工作记忆能力下降有密切关系.进一步分析发现,由工作记忆能力下降引起的数学学习困难与特定的工作记忆能力不足有关,即数学学习困难几乎完全是由于数字工作记忆能力下降引起,而与视空间工作记忆能力下降无关,这种由数字工作记忆下降而引起数学学习困难的更深层次原因可能在于较差的语音加工速度与中央执行功能二者的共同影响.

预防高校速滑课的运动损伤探析

速滑是北方各高校冬季体育课教学的主要内容,在高校速滑课教学中,非常容易发生运动损伤,而且参与人数较多,教学中意外损伤的发生也相应增加.由于速滑课出现的运动损伤较多,致使部分学生产生惧怕心理,直接影响冬季体育教学任务的完成,通过大量文献资料的整理、综合及分析,并针对高校的学生进行调查研究,总结出比较全面的容易造成运动损伤的原因,并提出一系列相应的预防措施,提高参加速滑课学生的保护意识,把速滑课的运动损伤率降到最低限度,从而提高高校速滑课教学的高效性.     

The experimental and case study of needle marks on the speedometer as the physical evidence for the collision speed analysis

The collision speed is important in accident analysis, and needle marks can be helpful as the physical evidence. The deceleration impact system has been built to analyze the mechanics of the needle and the gauge plate. Two isolated groups were designed to record the speed values under the same sample labels from real crashes. The visualization platform was built for the first group to collect needle marks. The second group recorded the speed values by other methods. The collision deceleration, the gauge plate materials, and the collision directions determine the forming of the needle marks. There were eight positive results from the 23 effective samples (12 frontal, four side, and seven rear), with discernible tip and/or middle marks on gauge plates. Multiple marks have been distinguished effectively. The low- and high-speed impacts have no obvious differences for real needle marks. It is more accurate for frontal impacts.
