爆炸冲击波作用下液体抛撒二次破碎的实验研究

本文采用高速摄影的方法拍摄了不同实验条件下液体抛撒的实验图片，实验结果表明：爆炸冲击波作用下液体颗粒产生二次破碎需一定的条件，不同的因素如液体密度、装盛液体量、装药量、表面张力等对液体抛撒二次破碎都产生显著影响。     

高铁隧道内气动效应形成损坏痕迹特点分析

动车高速通过隧道时,运行车体推动的空气由于受到隧道壁的约束能形成能量很强的冲击气流,有时会造成一些设备设施损坏、脱落,进而危及高铁行车安全。这类事件发生后,铁路部门往往误以为是人为破坏,并以破坏案件进行上报。本文通过对特定动车行车事故的现场勘验、调查访问,分析了高铁隧道内气动效应对特殊位置设施造成损坏的过程及形成痕迹特点,准确认定了事件性质和事故发生原因,并对气动效应形成损坏痕迹和常见工具形成痕迹的区别进行了探讨。     

玻璃破碎的物证分析研究

玻璃碎片及形态是案发现场常见的物证形式,开展对玻璃的物证分析研究,能够确定玻璃的来源与种类,推断玻璃破碎原因等,为案件的取证、重建和侦破提供线索和证据。简要介绍了常见玻璃的种类,分析了玻璃破碎的根本原因,总结了低速冲击和高速冲击下玻璃破碎的形态特征,还从玻璃碎片收集和检验两个方面探讨了玻璃实体物证的分析。     

动车车底和高铁线路损坏案件的现场勘查和技术鉴定

动车车底和高铁线路损坏案件的特点有发现时间与发生时间相隔长、勘查难度大、痕迹容易形成和异物容易发现等。动车车底痕迹有单条状擦划痕、多条状擦划痕、片状不规则裂痕等类型,线路损坏痕迹有轨道电线、电缆被砸坏,应答器等设备损坏和水泥枕、扣件等被损坏等类型。此类案件的勘查分两个部分：一是宏观勘查。在掌握受损动车的运营情况、发生发现经过等基本情况后,要对整列动车的前后机车、所有车厢进行全面的检查,确定哪些机车、车厢有破损、破损部位等情况,再把破损部位全面纳入微观勘查范围。二是微观勘查。对所有受损部位进行全面细致的勘查,从动车的一侧向另一侧详细记录受损的方向、位置、形态、大小,再进行全面的分析判断。     

Destructive Competition or Competition Destroyed? Regulatory Theory and the History of Irish Road Transportation Legislation

The principal aim of our study is to contribute to the debate over whether regulation is enacted in the interest of consumers, producers, political agents, or some combination of these. We examine the legislative debates and subsequent regulatory bills surrounding road transportation regulation in Ireland in light of the three dominant theories which purport to explain the existence of regulation: the public interest theory and the so-called Chicago and Virginia theories. A unique feature of our study is an attempt to integrate specific rhetorical concepts used in the public policy debates into the theoretical analysis of regulation. One noteworthy conclusion of our study is that theories of economic processes affect the shaping and results of public policy.

The Gautrain project in South Africa: a cautionary tale

This article analyses the recently completed Gautrain Rapid Rail Project in the province of Gauteng, South Africa. The Gautrain is the continent's first high-speed rail project, and constitutes an important case in transportation megaproject planning. The article discusses the potential merits and limitations of the project, and ultimately argues that several key problems with the Gautrain should provide readers with a cautionary tale regarding such endeavours. Benefits to the project, such as reduced traffic congestion and job creation, must be weighed against the social and political implications of the project. Thus, the article discusses the following potential problems with the project: it may deepen mobility-related exclusion in the province; it prioritizes wealthy, as opposed to poor, citizens in the allocation of public funds; costs for the project have escalated considerably from initial estimates; and other options for a more effective and integrated transportation plan were not sufficiently considered. This case study conforms to what scholars call the megaprojects paradox in significant ways, and suggests that more rigorous and transparent debate should precede the approval of such projects.     

Disquieting growth: urban space in Kawashima Yūzō's film Suzaki Paradise Red Light

This article examines how Japanese postwar cinematic texts manifest and comment upon contemporary political and economic events, and considers the usefulness of cinema for a more complete historical understanding of the period. In particular, it argues for the significance of fūzoku eiga, or ‘films of customs and manners’ by analyzing a representative text of that genre, Kawashima Yūzō's 1956 film Suzaki Paradise Red Light. Although Kawashima's film has been treated as an apolitical melodrama, a close textual analysis reveals it to be a counter-narrative to the success story of postwar economic recovery and growth that the Japanese state sought to promote. Key to this analysis is an examination of the urban space of the Suzaki neighborhood in Tokyo, as depicted in the film. Kawashima's tour of Suzaki addresses the issues of the economic stagnation within the metropolis, uneven development, and the liminal space of muen, or ‘no ties,’ which offers a brief refuge from an increasingly disciplined everyday life.

Endogenous Determinants for Renegotiating Concessions: Evidence from Local Infrastructure

The engagement of local government in public–private partnerships (PPPs) for the provision of infrastructure and public services is a global trend. Light rail services, water systems, waste management systems, schools, sport centres and social housing are simply a few examples of sectors in which the private sector is becoming more actively involved with local authorities. Most of these engagements are conducted through the use of mixed companies and contractual concessions. However, both of these uses suffer from a major shortcoming – renegotiations. Contracts are often renegotiated within a few years of being signed, and some evidence reveals that the results might not protect the public interest. This article aims to understand how and why renegotiations of local concessions occur by examining the specific characteristics of contracts (endogenous determinants). To illustrate the discussion, a case study of a light rail system is analysed, exemplifying the effect of a contractual renegotiation. The authors argue that contractual renegotiation can be useful in decreasing contract incompleteness, but a poorly designed contractual clause can allow for opportunistic concessionaire behaviour.
