轿车文明对都市社会空间的重塑

作为“流动的现代性”,轿车文明对当代城市社会发展的影响,绝不仅仅表现在便利快捷、产业利润、交通拥堵、噪音污染、尾气排放等具体而有形的利害层面,最具实质意义的是从根本上重塑了都市社会空间,并导致郊区的勃兴和内城的衰落、“公共领域”的私有化、城市空间的分化与隔离、“私”空间的流动性等剧烈变动。     

File fragment encoding classification—An empirical approach

Over the past decade, a substantial effort has been put into developing methods to classify file fragments. Throughout, it has been an article of faith that data fragments, such as disk blocks, can be attributed to different file types. This work is an attempt to critically examine the underlying assumptions and compare them to empirically collected data. Specifically, we focus most of our effort on surveying several common compressed data formats, and show that the simplistic conceptual framework of prior work is at odds with the realities of actual data. We introduce a new tool, zsniff, which allows us to analyze deflate-encoded data, and we use it to perform an empirical survey of deflate-coded text, images, and executables. The results offer a conceptually new type of classification capabilities that cannot be achieved by other means.     

Development of Individuality in Children's Handwriting

Handwriting of children in early grades is studied from the viewpoint of quantitatively measuring the development of handwriting individuality. Handwriting samples of children, in grades 2–4, writing a paragraph of text in both handprinted and cursive, collected over a period of 3 years, were analyzed using two different approaches: (i) characteristics of the word “and” and (ii) entire paragraphs using an automated system. In the first approach, word characteristics were analyzed using statistical measures. In the second approach, pairs of paragraphs were compared. Both types of analysis, single word and complete writing, led to the same conclusions: (i) handwriting of each child remains relatively similar when handwriting has been just learnt and becomes markedly different from grades 3 to 4 and (ii) handwriting of different children becomes progressively more different from grades 2 to 4. The results provide strong support that handwriting becomes more individualistic with child development.     

The different types of reports produced in digital forensic investigations

The importance of ensuring the results of any digital forensic (DF) examination are effectively communicated cannot be understated. In most cases, this communication will be done via written report, yet despite this there is arguably limited best practice guidance available which is specific for this field in regards to report construction. Poor reporting practices in DF are likely to undermine the reliability of evidence provided across this field, where there is a need for formalised guidance regarding the requirements for effective DF report construction; this should not be a task left solely to each individual practitioner to determine without instruction. For this, the field of DF should look to the wider forensic community and the existing work in this area for support. In line with many other ‘traditional’ forensic science types, a DF practitioner can be commissioned to report in one of three ways - ‘technical’, ‘investigative’ or ‘evaluative’, where each reporting type maintains a specific purpose and interpretative-context, determined by the examination workflow undertaken by a practitioner following client instruction. This work draws upon guidance set out in fundamental forensic science reporting literature in order to describe each reporting type in turn, outlining their scope, content and construction requirements in an attempt to provide support for the DF field.     

The manufacturing of Islamic lifestyles in Tajikistan through the prism of Dushanbe's bazaars

ABSTRACT

This article traces the multiple ways of ‘manufacturing’ Islamic lifestyles in the urban environment of Tajikistan's capital city, Dushanbe. The city's bazaars serve as a lens through which to observe the conjunction of its booming trade business with Dubai alongside its growing Islamic commodity culture and a religious reformism that is inspired by the materiality and non-materiality of a progressive and hybrid Dubai Islam. Bringing together long-distance trade, urban consumption practices and new forms of public piety in the mobile livelihood of three bazaar traders and sellers, the article provides insights into how the commodification of Islam informs notions of urbanity and modernity in Tajikistan. These notions correspond to the launching of urban renewal and the meta-narrative of Dushanbe's future as a modern city on the rise. Furthermore, the article illustrates the ways in which Dushanbe's Muslims turn bazaars into an urban laboratory for religious agency and cultural identities.     

I shop online – recreationally! Internet anonymity and Silk Road enabling drug use in Australia

Internet technologies are beginning to influence the sale and supply of illicit drugs in Australia. One such technology, an online marketplace known as Silk Road, had dramatically increased in popularity since its worldwide launch in February 2011. This research and paper were completed prior to the Silk Road's founder, Ross Ulbricht being arrested on 2 October 2013 and Silk Road being taken off line. This research paper will consider such factors; as the increasing use of internet by Australians, the popularity of shopping online and the variance in the quality and price of products available on Silk Road to those available in other drug markets. The case study will provide an in-depth look at Silk Road from an Australian perspective and in light of the continuing popularity of illicit drug use in Australia. Though Silk Road is currently off line, ‘Bitcoin’ has survived and it will only be a matter of time before a substitute for Silk Road emerges.     

Impacts of increasing volume of digital forensic data: A survey and future research challenges

A major challenge to digital forensic analysis is the ongoing growth in the volume of data seized and presented for analysis. This is a result of the continuing development of storage technology, including increased storage capacity in consumer devices and cloud storage services, and an increase in the number of devices seized per case. Consequently, this has led to increasing backlogs of evidence awaiting analysis, often many months to years, affecting even the largest digital forensic laboratories. Over the preceding years, there has been a variety of research undertaken in relation to the volume challenge. Solutions posed range from data mining, data reduction, increased processing power, distributed processing, artificial intelligence, and other innovative methods. This paper surveys the published research and the proposed solutions. It is concluded that there remains a need for further research with a focus on real world applicability of a method or methods to address the digital forensic data volume challenge.     

Private browsing: A window of forensic opportunity

The release of Internet Explorer 10 marks a significant change in how browsing artifacts are stored in the Windows file system, moving away from well-understood Index.dat files to use a high performance database, the Extensible Storage Engine. Researchers have suggested that despite this change there remain forensic opportunities to recover InPrivate browsing records from the new browser. The prospect of recovering such evidence, together with its potential forensic significance, prompts questions including where and when such evidence can be recovered, and if it is possible to prove that a recovered artefact originated from InPrivate browsing. This paper reports the results of experiments which answer these questions, and also provides some explanation of the increasingly complex data structures used to record Internet activity from both the desktop and Windows 8 Applications. We conclude that there is a time window between the private browsing session and the next use of the browser in which browsing records may be carved from database log files, after which it is necessary to carve from other areas of disk. It proved possible to recover a substantial record of a user's InPrivate browsing, and to reliably associate such records with InPrivate browsing.
