Comparison of glass fragments using particle-induced X-ray emission (PIXE) spectrometry

A procedure has been developed to analyze the trace element concentrations in glass fragments using particle-induced X-ray emission (PIXE) spectrometry. This method involves using accelerated protons to excite inner-shell electronic transitions of target atoms and recording the resultant X-rays to characterize the trace element concentrations. The protocol was able to identify those glass fragments that originated from different sources based on their elemental analyses. The protocol includes specific approaches to calculating uncertainties and handling measurements below the level of detection. The results indicate that this approach has increased sensitivity for several elements with higher atomic number compared with X-ray fluorescence methods. While not as sensitive as laser-ablation or inductively coupled plasma mass spectrometry methods of dissolved samples, it is entirely nondestructive and entails a much simpler sample preparation process that may be used to presort glass fragments for more comprehensive elemental analysis. As such, the technique described may have a niche role in forensic glass analysis.     

Household furniture tip-over deaths of young children

The potential for the injury or death of a child resulting from the tip-over of a piece of household furniture or a domestic appliance has not been previously well recognized. We reviewed nine accidental deaths of young children that resulted from avoidable residential hazards and/or lapses in supervision of the children by their caregivers. The offending household items included televisions, bedroom dressers, a kitchen stove, and a lounge chair. The causes of death were mechanical asphyxia, blunt trauma, and combined blunt head trauma and asphyxia. All of the deaths could have been prevented by appropriate anchoring of the piece of furniture and/or closer supervision of the child. A thorough multidisciplinary investigation is essential in establishing the cause and manner of death in such cases and in identifying risk factors that may aid in the prevention of future childhood deaths.

Courts' misplaced confidence in psychiatric diagnoses

In considering psychiatric evidence, criminal justice systems make considerable use of labels from official psychiatric classificatory systems. There are legislated requirements for psychological and/or behavioural phenomena to be addressed in legal tests, however medico-legal use of the current categorical diagnostic frameworks which are increasingly complex is difficult to justify. The lack of validity in large domains of the present classificatory systems is now more openly acknowledged, prompting a critical rethink. Illustrative examples include post-traumatic stress disorder, various personality disorders, and dissociative identity disorder. It follows that the Courts' faith in the present categorical classifications (e.g., DSMIV and ICD10) is misplaced and may be ultimately unhelpful to the administration of justice.     

Abolishing Some More Obsolete Crown Prerogatives

The Crown had many prerogatives (privileges) which other legal and natural persons did not have, due to the pre-eminent role of the sovereign. Some of these the Crown delegated to its subjects. That is, it franchised them, in return for money. In modern times??with the sovereign only having a formal role??it needs to be considered whether these Crown prerogatives should pass to the control of Parliament. Also, where they are obsolete, their abolition. A previous article has argued for the abolition of many obsolete prerogatives relating to the military. This article argues that the prerogatives of the Crown to levy pontage (a toll for the building, and repair, of bridges) and murage (a toll for the building, and repair, of town and city walls for defensive purposes) should be abolished. So too, the right of the Crown to waifs (stolen goods cast away by a thief in flight) and estrays (animals wandering in any manor or lordship whose owner is unknown). Also, that the prerogative of the Crown to unmarked mute swans in open water be restricted to the Thames??where it is only presently exercised. Finally, this article argues for the abolition of the palatinates of Lancaster, Chester and Durham??since the prerogatives once given to them by the Crown have now reverted to the same??and for the abolition of various long obsolete prerogatives given to the Cinque Ports.     

Homeowners Associations as Private Governments: What We Know,What We Don’t Know,and Why It Matters

Homeowners associations (HOAs) are private governments that are reshaping urban governance and service delivery in large parts of the United States. Despite the fact that millions of Americans are HOA members, the field of public affairs has paid scant attention to these new governance entities. The essays in this symposium call attention to HOAs’ potential effects on urban services and civic life in the hope of sparking interest among scholars and public managers to include HOAs in our understanding, research, and teaching of contemporary urban governance.     

Paths to destruction: the lives and crimes of two serial killers

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities.     

When (Some) Prostitution is Legal: The Impact of Law Reform on Sex Work in Australia

In Australia, prostitution regulation has taken a very different path from many other countries. Law reform has led to the opening of some significant new spaces for legal sex work, including the (very different) regulatory regimes established in two Australian states – Queensland (brothels legal if their owners are licensed) and New South Wales (most commercial sex businesses and some street prostitution decriminalized; no licensing regime). The main research question is: how has regulation impacted on the positive rights of sex workers? I argue that law reform has engaged a mix of neo-liberal and other approaches – not to increase personal or corporate freedom but as part of a practical strategy designed to control a range of social problems, such as police corruption and organized crime. Neo-liberal regulation of prostitution in Australia has always been deployed in tandem with other modes of regulation – including new criminal law and policing strategies, planning law, health regulations, and (of course) moral regulation.     

Building sustainable free legal advisory systems: Experiences from the history of AI & law

The enthusiasm for artificial intelligence (AI) as a source of solutions to problems is not new. In law, from the early 1980s until at least the early 2000s, considerable work was done on developing ‘legal expert systems.’ As the DataLex project, we participated in those developments, through research and publications, commercial and non-commercial systems, and teaching students application development. This paper commences with a brief account of that work to situate our perspective.The main aim of this paper is an assessment of what might be of value from the experience of the DataLex Project to contemporary use of ‘AI and law’ by free legal advice services, who must necessarily work within funding and other constraints in developing and sustaining such systems. We draw fifteen conclusions from this experience, which we consider are relevant to development of systems for free legal advice services. The desired result, we argue, is the development of integrated legal decision-support systems, not ‘expert systems’ or ‘robot lawyers’. We compare our insights with the approach of the leading recent text in the field, and with a critical review of the field over twenty-five years. We conclude that the approach taken by the DataLex Project, and now applied to free legal advice services, remains consistent with leading work in field of AI and law.The paper concludes with brief suggestions of what are the most desirable improvements to tools and platforms to enable development of free legal advice systems. The objectives of free access to legal information services have much in common with those of free legal advice services. The information resources that free access to law providers (including LIIs) can provide will often be those that free legal advice services will need to use to develop and sustain free legal advisory systems. There is therefore strong potential for valuable collaborations between these two types of services providers.
