Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Introduction

ABSTRACT

This article argues for the analysis of the flow of ideological discourse through society within and across three distinct but interrelated levels: (1) the canonically defined, or macro level, (2) the intermediate or meso level of competitive political appeals, political relevant public discourse and cultural criticism, and (3) the everyday or micro level of conceptual use by non-experts. This differentiation among levels of ideological action and influence helps us to clarify the objects and appropriate methods of ideological analysis. Methods applied in specific cases must facilitate an effective focus on phenomena on one of these levels while still allowing recognition of the complex forms of direct and indirect conceptual influence and connection between the levels. The article also serves as an introduction to the volume, giving a brief account of the analysis and argument of each contribution.     

Australian Cinema Studies: How the Subject Is Taught in Australian Universities

Since the mid-1970s, the subject Australian Cinema, and its various synonyms and neologisms, has been studied in humanities, social sciences and the arts in Australian higher education, and research in the field has played an important role in informing the critical approaches underpinning curriculum. Yet to date there is limited insight into the types of subjects offered, approaches to curriculum and syllabus, and their alignment with research. This article maps Australian cinema studies in higher education at an undergraduate level, and provides insight into common curriculum and syllabus models. Findings are drawn from an online survey of university course handbooks, content and thematic analysis of study guides and weekly syllabus, and correspondence with coordinators. Twenty-seven universities offered subjects with a dominant Australian cinema focus. Australian cinema studies is firmly embedded in national cinema curriculum, and three common curriculum models include the following: (1) a historical chronology of Australian cinema, (2) a text-dominant approach organised around the weekly study of a key film and (3) an approach predominately structured around Australian cinema discourses and critical theory. Despite the increasing importance of transnational approaches to Australian screen in research, transnationalism rarely functions as a dominant organising logic for curriculum in its own right.     

Administrative Innovations and Accountability Failures: The Termination of the Spanish Telecommunications Agency

We discuss how far accountability practices may be relevant to the success of independent regulators in countries without a tradition of administrative autonomy. We develop a conceptualisation of agency accountability failures and develop an analytical framework to examine the life and termination of the Spanish regulatory agency for telecommunications, CMT (Comisión del Mercado de las Telecomunicaciones - Telecommunications Market Commission). We argue that the CMT’s termination was related, among other reasons, to accountability failures in its institutional design. The paper relies on a variety of sources, including legislation, literature, media coverage, and semistructured interviews with agency officials and several stakeholders.

Body mass and suicide risk

Body mass has been neglected as a possible predictor of suicidal behavior. The present investigation explores the association between body mass index and completed suicide. Data are from the National Mortality Followback Survey and refer to 373 suicides, and 518 deaths from motor vehicle accidents as controls. The results of a logistic regression analysis indicated that, for females, the greater the BMI the greater the suicide risk. However, this relationship did not hold up under controls for race and other covariates of BMI. For males, the BMI was not significantly related to suicide risk either at the bivariate or multivariate levels of analysis. The best predictors of suicide were living alone for females, and alcohol abuse for males.
