Photogrammetry vs CT Scan: Evaluation of Accuracy of a Low-Cost Three-Dimensional Acquisition Method for Forensic Facial Approximation

Photogrammetry is a three-dimensional acquisition method potentially applicable to the forensic field. This possibility requires the verification of its accuracy. In this study, 3D volumes of skulls are generated to compare the photogrammetry versus the CT scan. In order to provide eligible material to the photogrammetric software, photographs were captured at a distance of 30 cm from the skull placed on a support 1 m in height and illuminated with diffused laboratory ceiling artificial light. A Nikon Coolpix P7100 camera was used. Photographs capture common elements with the previous and the next photograph so as to allow the photogrammetric software to recognize these common points between photographs and create a 3D puzzle. The Zephyr Lite (3DFlow©) software was employed to register the 3D volume. CT-based skulls are taken as a metric reference. The photogrammetry-based skulls are then enlarged according to the measurements of some landmarks or Zygion and Zygion, the distance between end of nasal and base of nasal pyramid for frontal projection, and minimum breadth of the mandibular ramus for the right lateral projection. The accuracy of the photogrammetry is compared to that of the CT scan by measuring the 3D volumes of the skulls studied. Specific landmarks are used as reference points for the measures in both frontal and lateral views. Bland–Altman graph shows homogeneity. The mean difference (1.28 mm) indicates that the measurements taken on the photogrammetry-based skull tend to slightly overestimate compared with the measurements taken on the CT-based skull.     

A New Robust Epigenetic Model for Forensic Age Prediction

Forensic DNA phenotyping refers to an emerging field of forensic sciences aimed at the prediction of externally visible characteristics of unknown sample donors directly from biological materials. The aging process significantly affects most of the above characteristics making the development of a reliable method of age prediction very important. Today, the so-called “epigenetic clocks” represent the most accurate models for age prediction. Since they are technically not achievable in a typical forensic laboratory, forensic DNA technology has triggered efforts toward the simplification of these models. The present study aimed to build an epigenetic clock using a set of methylation markers of five different genes in a sample of the Italian population of different ages covering the whole span of adult life. In a sample of 330 subjects, 42 selected markers were analyzed with a machine learning approach for building a prediction model for age prediction. A ridge linear regression model including eight of the proposed markers was identified as the best performing model across a plethora of candidates. This model was tested on an independent sample of 83 subjects providing a median error of 4.5 years. In the present study, an epigenetic model for age prediction was validated in a sample of the Italian population. However, its applicability to advanced ages still represents the main limitation in forensic caseworks.     

Investigations into Enhancing Yersinia pestis Cells Viability following Environmental Sampling for Forensic Analysis

Following an intentional or accidental bio-warfare agent (BWA) release, environmental sample analysis is absolutely critical to determine the extent of contamination. When dealing with nonspore forming BWA (e.g., Yersinia pestis), retention of cell viability is central to such analyses. Even though significant advances have been achieved in DNA sequencing technologies, a positive identification of BWAs in environmental samples must be made through the ability of cells to form colony-forming units upon culturing. Inability to revive the cells between collection and analysis renders such studies inconclusive. Commercial kits designed to preserve the viability of pathogens contained within clinical samples are available, but many of them have not been examined for their ability to preserve samples containing suspected BWAs. The study was initiated to examine the applicability of commercial solutions aiding in retention of Y. pestis viability in samples stored under nonpermissive temperatures, that is, 40 and 37°C. While none of the tested solutions sustained cell viability at 40°C, the results show five out of 17 tested preservatives were capable of supporting viability of Y. pestis at 37°C.     

Wanting Pictures After Feminism: Re-reading On Our Backs

Abstract

This article explores the relationship between photography and feminism that emerges through the pages of the lesbian sex magazine On Our Backs (1984–2006). The San Francisco-based magazine represents an exceptional archive of images made in the context of lesbian community. Returning to the photographs that were published in early issues of the magazine, the article argues that On Our Backs, whilst explicitly addressed to a paucity of available images of lesbian culture, reflects a complex engagement with the meaning of the photographic image in dialogue with contemporaneous feminist debates. Through the work of Tee Corinne, Morgan Gwenwald and Honey Lee Cottrell, a desire for pictures renders the image a site of fantasy in which different ways of inhabiting lesbian identity form in dialogue with a community of readers.     

Can agricultural intensification help attain Sustainable Development Goals? Evidence from Africa and Asia

Market-oriented agricultural intensification is a major development strategy, yet its alignment with sustainable development goals (SDGs) is unclear. We apply indicators for SDG 2 (eradicate hunger) regarding income, food production, food security and land tenure to recent intensifications in Rwanda and Laos to reveal their disaggregated impacts. We find while market-oriented intensification may generate poverty reduction, it also exacerbated marginalisation and poverty through various forms of land tenure insecurity. Ethnicity and gender were influential factors in Rwanda, and post-conflict resettlement policies in Laos. We discuss implications for development practice and selection of suitable indicators to reflect the ambition of the SDGs.     

Women in the world of work: Past,present, and future

Women have not been usually credited with much Utopian writing, but in fact a number of women writers have projected societies which seek to improve the condition of their sex. This paper examines three eighteenth century English women writers's ideas of feminist utopias: Mary Astell's A Serious Proposal, Sarah Robinson Scott's Millenium Hall, and Clara Reeve's Plans of Education. It discusses their ideas on the rationale and organization of communities of women and how these communities could extend their benefits to society as a whole. It will also discuss the limitations of the thinking of these women for the reform of society especially in regard to woman's place.     

Seeing land deals through the lens of the ‘land–water nexus’: the case of biofuel production in Piura,Peru

ABSTRACT

This contribution examines two large-scale land acquisitions on Peru’s northern coast, using a ‘land–water nexus’ approach. The establishment of large sugarcane monocultures resulted in a massive transfer of land and water rights from smallholders to biofuel companies. Using Ribot and Peluso’s theory of access, we demonstrate that this transfer of rights was enabled by the convergence of neoliberal land and water reforms and the presence of the two investors. This constellation (1) altered smallholders’ bundles of rights; and (2) created sharp imbalances that radically changed access to land and water, not only through changing bundles of rights, but also, and maybe more significantly, through widening the gaps between smallholders’ and biofuel companies’ bundles of powers. Using Hall et al.’s powers of exclusion approach, we identify the processes both underpinning and resulting out of the changing access relations analyzed in this study. Changes to Peru’s water governance may accentuate power asymmetries between investors and smallholders, constraining locals’ access to increasingly scarce water.

The radical avant-garde has aged profoundly. Yet, led by director Judith Malina, the Living Theatre, founded in 1947, remains the longest surviving political theatre collective in the US. The Living Theatre opened its doors at a new theatre/home on New York City's Lower East Side in 2007, where Malina directed a much lauded revival of the company's groundbreaking 1963 production of Kenneth Brown's The Brig, and performed the role of Maudie in the premiere production of Hanon Reznikov's adaptation of Doris Lessing's Maudie and Jane. Vibrant and luminous at 81, an aged Venus rising from the half shell, Malina (dis)played the decaying and decrepit Maudie, standing naked onstage, sensually and lovingly bathed by Pat Russell, playing Jane. Malina's ageing activist/artist's body and voice spoke volumes about decades of societal and cultural transformations, of sexual revolutions, and of wounds that never heal.

Evoking Pierre Nora's ‘sites of memory’—this performative lieu de memoire ‘talks back’ on many levels, both in contemporary contexts and re-membering the zeitgeist of Malina's earlier performances—nearly naked, strident and much younger in the Living Theatres’ legendary production of Paradise Now (1968–70), and eloquently, flamboyantly anarchist, if too old, playing Antigone in Malina's adaptation of Brecht's version of Sophocles play (1967–84). This essay analyses the mise en scène and the reception of Maudie and Jane in light of the working processes and performance history of director/performer/inspirator Malina. Finally, the challenges and hope made visible and corporeal in Malina's on- and off-stage performances are explored.     

Primum Mobile: Women and Auto/mobility in the Era of the Great War

Abstract: This article explores the construction of Andrea Dworkin as a public persona, or a ‘feminist icon’, revered by some and demonized by others. It argues that in both her fiction and non-fiction, Dworkin engaged in a process of writing herself as an exceptional woman, a ‘feminist militant’ as she describes herself in the subheading of her 2002 memoir, Heartbreak. The article illustrates Dworkin's autobiographical logic of exceptionalism by comparing the story told in Heartbreak to the story of Dworkin's major novel, Mercy, which features a heroine, Andrea, who shares Dworkin's name and significant biographical details. While Dworkin has insisted that Mercy is not an autobiographical novel, the author undertakes a reading here of Mercy as the story of Dworkin if she had not become the feminist icon of her own and others' construction. In Mercy, Andrea unsuccessfully attempts to escape the silent, victimized status that Dworkin has insistently argued is imposed upon women. In her repeated victimization, Andrea functions for Dworkin as an ‘everywoman’ who both embodies Dworkin's world-view and highlights how Dworkin's own biography exists in tension with some of her central assumptions about women, gender and contemporary society.
