手机物证检验及其在刑事侦查中的应用

随着移动通信技术的迅速发展和广泛应用,手机内部包含的信息已经成为犯罪侦查重要的线索和证据来源。采用专门的符合物证鉴定原理要求的技术方法检验手机的SIM卡存储器、主板存储器和闪存卡,可以获得大量的手机使用者个人信息、通信内容信息、通信发生信息、使用者写入存储信息和手机设置信息等大量信息资料。手机检验结果给出的这些信息具有非常高的侦查和证据价值的,手机也因此成为物证鉴定领域内一个新的检验对象。     

High-frequency trading,algorithmic finance and the Flash Crash: reflections on eventalization

The Flash Crash of 6 May 2010 has an interesting status in discussions of high-frequency trading, i.e. fully automated, superfast computerized trading: it is invoked both as an important illustration of how this field of algorithmic trading operates and, more often, as an example of how fully automated trading algorithms are prone to run amok in unanticipated frenzy. In this paper, I discuss how and why the Flash Crash is being invoked as a significant event in debates about high-frequency trading and algo-financial markets. I analyse the mediatization of the event, as well as the variety of eventalizations of the Flash Crash - the different ways in which the Flash Crash is being mobilized as an illustrative event. I critically discuss the impact often associated with the Flash Crash – and on that basis, inquire into why the event nonetheless attracts so much attention. I suggest that a key reason why the Flash Crash is widely discussed is that eventalizations of 6 May 2010 evoke familiar tropes about the fear of technology and the fear of herding. Finally, and given their emphasis on herding, I argue that the Flash Crash eventalizations may contribute to discussions within economic sociology about resonance in quantitative finance.     

Bugs,predations or manipulations? Incompatible epistemic regimes of high-frequency trading

Abstract

Calls for greater transparency as well as corporate and individual accountability have emerged in response to the recent turbulence in financial markets. In the field of high-frequency trading (HFT), suggested solutions have involved a call for increased market information, for example, or better access to the inner workings of algorithmic trading systems. Through a combination of fieldwork conducted in HFT firms and discourse analysis, I show that the problem may not always stem from a lack of information. Instead, my comparative analysis of different market actors (regulators, market analysts and traders) shows that the diverse and complex ways in which they access and construct knowledge out of information in fact lead to what I call different epistemic regimes. An understanding of how epistemic regimes work will enable us to explain not only why the same market event can be viewed as very different things – as market manipulation, predation or error – but also why it is so difficult to arrive at a unified theory or view of HFT. The comparative perspective introduced by the idea of epistemic regimes might also serve as a starting point for the development of a cultural approach to the study of financial markets.

The big,bad wolf and the rational market: portfolio insurance,the 1987 crash and the performativity of economics

This article distinguishes two meanings of the performativity of economics, a thesis advanced by Michel Callon: ‘generic’ performativity, according to which markets and other economic relations are not to be taken as given, but as performed by economic practices; and ‘Austinian’ performativity, in which economics brings into being the relationships it describes. The two versions of performativity are explored by means of an examination of the history of portfolio insurance (a financial-market technique based on the economics of option pricing), of the 1987 stock market crash, and of subsequent efforts to diagnose the causes of the crash and to redesign the market to avoid future catastrophe. The article emphasizes the extent to which the financial markets of high modernity are designed entities, and argues that the question of their design is always a political question, even if it is seldom recognized as such.     

An investigation of anonymous and spoof SMS resources used for the purposes of cyberstalking

In 2012, the United Kingdom actively sought to tackle acts of stalking through amendments to the Protection from Harassment Act 1997. Now, not only is stalking a recognised criminal offence, acts associated with stalking behaviour have finally been properly defined in legislation. Further, the role of technology in digital stalking offences, frequently termed as acts of cyberstalking, has been duly highlighted. The prosecution of such cyberstalking offences is reliant on the forensic analysis of devices capable of communication with a victim, in order to identify the offender and evidence the offending content for presentation to a court of law. However, with the recent proliferation of anonymous communication services, it is becoming increasingly difficult for digital forensic specialists to analyse and detect the origin of stalking messages, particularly those involving mobile devices. This article identifies the legal factors involved, along with a scenario-based investigation of sample anonymous and spoof SMS (Short Message Service) messages, documenting the evidence that remains on a victim's handset for the purpose of locating an offender, which often may be minimal or non-existent.     

Motorcyclists’ fatalities in multiple crashes: Who is responsible for death? (three cases)

In Italy in 2007, 26% of two-wheeled motor vehicle injury/fatalities concerned motorcyclists. However, it is rare (4%) that a motorcycle (MC) crashes with two other road users and even more exceptional is a crash between a MC and three other vehicles. In general, in MC–vehicle crashes, the vehicle driver is at fault in more than 50% of the cases and the motorcyclist in 37%. The study concerns three MC lethal road accidents in which the culpability of the motorcyclist's death was questioned by the prosecutor because it was supposed that one or more vehicles ran over the motorcyclist after a fall. The crucial question in these three cases was if it was possible to assign injuries to a specific crash-aetiology and to assign/exclude the responsibility of motorcyclist's death to a defined subject (motorcyclist himself and/or car drivers) after a crash-dynamics study made by an engineer consultant or by the police authority. Case (1) A 56-year-old motorcyclist on a highway had a front–rear end collision with a car that suddenly stopped; he was therefore projected against a concrete traffic island, thrown on the soil and run over by another car. Case (2) A 29-year-old motorcyclist on the East ring road fell on the soil, perhaps by a supposed front–rear end contact with a car and was run over by two cars in rapid succession. Case (3) A 34-year-old motorcyclist on the North ring road fell suddenly on the soil for unknown reasons; during first aid, the medical team around him was run over by the ambulance which pushed after a rear-end collision with a car. A stepwise analysis of the indicated crash dynamics and an evaluation of all the injuries revealed at autopsy, the study proposed, when possible, injury aetiology for each case and the related responsibility assignments and exclusions.
