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.     

Semiotising the student perception of learning outcomes in British higher education

This article presents a semiotic analysis of the student perception of learning outcomes in British higher education. It centres on three annotated images in Frank Furedi’s article “The Unhappiness Principles”, published in Times Higher Education in 2012. Drawing upon Peircean semiosis and iconicity, it provides a rhetoric-infused interpretation of the word–image complementarity exhibited in student participants’ written commentaries on the three images. This leads to a dialectical view of formative and summative assessment, in which process and product create each other through the same continuum of learning and teaching. In highlighting intellectualism as central to the ethnography of university life, this article argues that learner autonomy and the potential for transformation is deemed essential to the student experience in higher education.     

“We have to tell our own story”: semiotics of resisting negative stereotypes of Nigeria in the heart of Africa nation branding campaign

This study examines the semiotic resources deployed in resisting negative stereotypes of Nigeria in the international community, particularly representations of the country in the Western media. Data for the study were drawn from Nigeria’s Heart of Africa nation branding campaign. The study applies the discourse-historical approach (DHA) pioneered by Ruth Wodak of the Vienna School of CDA. DHA attempts to integrate much available knowledge about the historical sources and the background of the social and political fields in which discursive events are embedded. Further applying Reisigl and Wodak's presentation of the discursive strategies normally oriented towards understanding texts related to nations and national identities, among others, the study reveals that in appropriating the semiotic resources in the campaign, the discourse producers have predilection for the discursive strategies of mitigating negative attributes which the out-group intensifies, and highlighting positive attributes which the out-group seemingly under-reports in its representations of Nigeria. Notwithstanding the rhetorical dynamics of the semiotic resources, the study concludes that enduring national image management thrives on creating new images and associations lived by a country’s citizens rather than tries to refute old ones.     

明星模仿的侵权认定与例外——以形象权保护为视角

我国法学界对明星模仿涉及的法律问题给与了很多讨论,讨论的主题涉及明星模仿的方式、侵权构成要件、法律规制等方面。目前来看,理论界对于明星模仿侵犯了权利人的合法权益并无异议,但对于认定侵权的标准和侵犯了权利人何种权益等问题仍有待进一步讨论。本文试图引进形象权的概念和形象权理论中＂附带使用＂规则对明星模仿侵权相关理论进行分析。

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.     

Bulging biceps and tender kisses: the sexualisation of fatherhood

This article explores recent developments in masculinity, focusing on the sexualisation of fatherhood in Anglophone media. As it becomes socially acceptable for men to engage with “hands-on” fatherhood roles that had previously been primarily associated with motherhood, the appeal lies not just in this shift in gendered performance, but the representation of this as an opportunity for men to reveal a desirably body image. Where previously the hands-on fatherhood role had been glossed as “nappy changing duties,” this more recent development focuses on men’s bodies and in particular the act of carrying a young child which affords the chance for biceps to be flexed in juxtaposition with the gentle act of holding a child. Colloquially, this has led to the emergence of the “DILF,” particularly on social media where sites are devoted to photos of such men.     

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.
