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.     

Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

‘Multicolored’ green criminology and climate change’s achromatopsia

While green criminology may be an effective name or label for the sub-field or perspective within criminology that considers a wide range of environmental issues, it is, in reality, a ‘multicolored green’ – a criminology that engages a spectrum of issues, that reflects the interests of some racial groups more than others, that reveals and analyzes environmental harms which disproportionately impact some racial groups more than others, and that can be approached from a number of vantage points or that can be viewed with variously tinted lenses. This article begins with an overview of climate change, including a discussion of its anticipated impacts and indicators of its already-being-felt effects. It then offers some general comments on the disproportionate impact of environmental threats and harms before turning to a discussion of the present and anticipated distributional impacts of climate change. Here, this article argues that climate change is, in effect, achromatopsic – it is color-blind, in that it affects us all regardless of skin color – but that those impacts will be distributed unevenly/unequally and that various groups are and will continue to be in different positions to adapt to climate change. This article concludes by suggesting that while the environmental harms caused by climate change are real – and the risks and threats they pose tangible and serious – climate change presents an exciting challenge for our creative potential as humans. In the process of reducing our consumption of fossil fuels and stabilizing (or, better yet, reducing) our greenhouse gas emissions, we might better assist those geopolitical regions most at risk (i.e. poor, developing countries) to become more resilient – an approach that is necessary for both the physical health of the planet and the prospects for social justice.
