Empirical Evaluation of the Reliability of Photogrammetry Software in the Recovery of Three-Dimensional Footwear Impressions

This paper examines the reliability of Structure from Motion (SfM) photogrammetry as a tool in the capture of forensic footwear marks. This is applicable to photogrammetry freeware DigTrace but is equally relevant to other SfM solutions. SfM simply requires a digital camera, a scale bar, and a selection of oblique photographs of the trace in question taken at the scene. The output is a digital three-dimensional point cloud of the surface and any plastic trace thereon. The first section of this paper examines the reliability of photogrammetry to capture the same data when repeatedly used on one impression, while the second part assesses the impact of varying cameras. Using cloud to cloud comparisons that measure the distance between two-point clouds, we assess the variability between models. The results highlight how little variability is evident and therefore speak to the accuracy and consistency of such techniques in the capture of three-dimensional traces. Using this method, 3D footwear impressions can, in many substrates, be collected with a repeatability of 97% with any variation between models less than ~0.5 mm.     

How to share and utilise expertise in a police forensic department through externalisation and mutualisation

The technique of fire investigation is a forensic domain in which expertise and analogies play a central role. To learn how fire investigators use these analogies to support their work, we conducted an ethnographic study in a Swiss forensic police department. To propose a suitable knowledge-management strategy, we also evaluated the knowledge conservation and sharing within the department. Our results highlighted that actionable knowledge is registered mainly in the investigators’ memories of a few, very experienced, individuals. Without experience with fire-incident investigations, an agent generally requires help from a more experienced colleague, who will then use his memory to find a similar case, which can contribute to the solution of the ongoing one. The research also established that knowledge is exchanged orally during on-site investigations and that knowledge receivers are generally those who are present on the scene. Using these findings, we suggest building a case library to support the externalisation and sharing of knowledge.

Just Use What You Have: Ethical Fashion Discourse and the Feminisation of Responsibility

ABSTRACT

The rise of fast fashion has meant that young women (even those on relatively low incomes) are able to ‘regularly consume and discard fashionable clothing’ [Buckley, Cheryl, and Hazel Clark. 2012. “Conceptualizing Fashion in Everyday Lives.” Design Issues 28 (4): 18–28. doi:10.1162/DESI_a_00172., 21]. While this development may be aligned with the democratisation of fashion—the fact that the supply chains that deliver fast fashion are not consistent with the principles of global democracy is now also relatively common knowledge in the democratised West. This, along with growing awareness of the ecological harms associated with the fashion industry has contributed to what Elke Gaugele [2014. Aesthetic Politics in Fashion. Vienna: Sternberg Press] has termed the ‘ethical turn’ in fashion. However, despite the fact that young women are often not deemed capable of translating their (ethical) attitudes into (ethical) behaviours [McNeill, Lisa, and Rebecca Moore. 2015. “Sustainable Fashion Consumption and the Fast Fashion Conundrum: Fashionable Consumers and Attitudes to Sustainability in Clothing Choice.” International Journal of Consumer Studies 39 (3): 212–222], nor able to be ‘trusted to consistently make good decisions’ [Brooks, Andrew. 2015. Clothing Poverty: The Hidden World of Fast Fashion and Second-Hand Clothes. London: Zed Books, 241], they are also increasingly being called to recognise their individual role in the politics of global fashion supply chains. Drawing on examples from scholarly and popular discourses as well as online peer to peer communications, this article explores the historical moment of fast fashion as an instance of both the feminisation of consumption and the feminisation of responsibility.     

Gender and Vernaculars in Digital Humanities and World Literature

Abstract

This article discusses the large-scale and world-encompassing aspirations of digital humanities and world literature and their methodological accordance with the analysis of literature in smaller languages and of texts understood in social, transnational, and gendered contexts. Are Digital Humanities and World Literature establishing themselves as fields utilizing analytical tools that are at odds with the aims and perspectives of feminist literary history and reception history as a part of literary history? We argue that gender research and theory is insufficiently developed in both computational literary history and World Literature. An unproblematic understanding of translations, canonization, English as a global language, and the use of large-scale computational methods and formalized interpretive models is in many cases not beneficial for the understanding of texts by women writers or from feminist perspectives. Drawing on feminist criticism of computational methods and arguments for specialized rather than generalized knowledge about literary history, we propose that digitization in some form, be it a bibliographical database or digitization of a corpus of texts, may be thought of as part of the research process in projects oriented towards gender and cultural exchange.     

A Study of Transnational Communication Among Iranian Migrant Women in Australia

Through the analysis of 25 interviews with Iranian migrant women in Australia, this study shows how living in different communicative environments can affect transnational communication practices. The case of these Iranian transnational families indicates that the digital divide, in terms of information and communication technology (ICT) infrastructure and communication capacity, may affect the technological quality of ICT-mediated communication. However, the digital divide does not significantly affect the frequency of communication among these families. The findings illustrate that the Iranian migrants in Australia and their family members overseas developed innovative communication practices and went to great lengths to maintain “ordinary” family interactions across national borders.     

Here be monsters: a choreomaniac's companion to the danse macabre

Consider this a vade mecum: an invitation to “walk with me” through more or less uncanny terrains of worlds in the making in search, of(f) course, of monsters. The search will be delving into the areas of “creepypasta:” pieces of cursed prose and pictures that circulate online, waiting to contaminate and possess the next reader. Using a theoretical framework of posthuman and feminist theory, not least the work done by Jacques Derrida and Donna Haraway, this vade mecum asks what it might mean to engage ethically with that which is not supposed to exist, but which haunts us nonetheless. In other words: what does it mean to move, live and engage with spectres in digital times?     

The trouble with ‘women in computing’: a critical examination of the deployment of research on the gender gap in computer science

The pessimistic scenario for ‘women in information communications technology’ and for ‘women in technology’ generally is even more paradoxical and insidious with respect to ‘women in computing’. Studies within this field not only report insignificant improvement in the proportion of women in Western countries’ computing fields but also alert us of a declining trend. Moreover, that decline has been accompanied – or even preceded – by years of research and programs that have specifically focused on increasing women’s participation in computing; however, they have not had the expected effect. More surprisingly, there has been a significant increase in the representation of women in all other science-related fields and professions. Our aim is to provide some clues to fight the feeling of inexorability that may be entailed by the research on women in computing. We will argue that part of the problem is related to the static nature of the research deployed around the problem of ‘women in computing’, primarily, the research constructed around the ‘leaky pipeline’ metaphor. We provide a synthesis of the critiques this research has received in recent decades and highlight research trends that render other landscapes visible when studying ‘women in computing’. These trends help us question how we are conducting research within this field and urge us to problematise assumptions about computing and gender that we may paradoxically continue to reproduce even while denouncing the paucity of women in computing and studying the reasons for this state of affairs. In short, we present the need for different researchers’ eyes that allow different landscapes of women and computing to be seen and produced.
