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.     

The Anti-Axial Age

Karl Jaspers famously characterized the period from the beginning of the eighth to the end of the third century before Christ as an “Axial Age” in which intellectual freedom and creativity blossomed as never before. This article argues that it was followed, five hundred years later, by an “Anti-Axial Age”, which devised a novel formula for intellectual and political repression. Its essence was the state’s capture of the millenial narrative, which had first been developed as religious doctrine within Zoroastrianism and Christianity. Involving the two great classical empires of Western Eurasia, Persia and Rome, and then empowering the expansion of Islam, the Anti-Axial Age left an ideological legacy that continues to haunt the contemporary world.     

Police Perceptions of Irrational Unstable Behaviours and Use of Force

Police identification of people experiencing mental illness is usually based on either the person having an official contact history with police or through observing behavioural indicators commonly associated with mental illness during an encounter. Police have voiced concerns with their ability to identify and respond to people experiencing mental illness in a timely way and report that they commonly resort to more coercive tactical options to resolve encounters. The present study employed a mixed method design to examine 286 police use of force incidents to investigate the association between force used on and by offenders displaying irrational-unstable behavioural characteristics. The irrational-unstable offenders were two times more likely to be perceived by police to have an apparent mental disorder and almost four times more likely to have a known mental health history; one in six had an official record of contact with mental health services. There were few differences in police and offender use of force, considering force as both a categorical and a continuous variable, while incident-level comparisons suggested that police force was generally proportional to offender resistance. Implications are discussed in terms of the need to redress limitations with the traditional police approach style.
