Economic Interests and Threat Assessment in the US Congress, 1890–1914

Why do some domestic actors see the international environment as a threatening place populated by untrustworthy powers, when others find opportunities for peaceful cooperation in the same conditions? Because these actors confront the same international environment, the reasons for their divergent evaluations must rest on differences in their own beliefs and interests. In this article, we consider the impact of societal interests in trade and trade protection on elite assessments of the international environment. We examine evaluations of the international environment in speeches given in the US Congress during naval appropriations debates between 1890 and 1914. The manufacturing sector’s interest in trade protection led political leaders who represented manufacturing regions to offer more negative assessments of the international environment, while those representing export-oriented agricultural areas of the country gave more positive evaluations. These effects were roughly comparable to those associated with party, as well as individual-level characteristics, such as having served as a military officer.     

Utilized coefficient of friction during walking: static estimates exceed measured values

This study compared utilized coefficient of friction (COF) measured during nonslip pedestrian gait to estimated utilized COF values calculated using anthropometric (i.e., leg length) and stride characteristic data (i.e., impact angle, step length). Twenty healthy adults walked at slow, medium, and fast speeds with kinematic and kinetic data recorded simultaneously. Estimated and measured impact angle varied with walking speed, with greater angles evident with faster speeds (p < 0.001 and p < 0.05, respectively). The estimated impact angle was greater than the measured impact angle (p < 0.05). Estimated and measured peak utilized COF values varied with walking speed, with higher utilized COF values evident with faster speeds (p < 0.001 and p = 0.001, respectively). Estimated utilized COF values were 86, 118, and 131% greater than measured peak utilized COF values for slow, medium, and fast speeds, respectively (p < 0.001). Higher estimated utilized COF values varied moderately with increased measured peak utilized COF values (r = 0.522; p < 0.001). These data suggest that impact angle and step length alone cannot be used to accurately assess the utilized COF on level walking surfaces.     

Forensic applications of infrared chemical imaging: multi-layered paint chips

This paper examines the potential of infrared chemical (hyperspectral) imaging as a technique for the forensic analysis of automotive paint chips in particular, and multicomponent (e.g., layered) samples in general. Improved sample preparation procedures for the infrared analysis of paint chips are detailed, with the recommendation that where mounting resins are chemically incompatible with the sample, it is better to mount and section the sample in a soft wax from which the sections can be removed and pressed into a KBr disk for transmission analysis. Infrared chemical images of multilayered paint chips have been successfully obtained, with the chief advantage over conventional infrared analysis being that thousands of infrared spectra are collected in a few minutes across the whole sample, at a spatial resolution of around 5 microm. As with conventional infrared spectroscopy, chemical species can be identified from their spectra, but the wealth of information available can be also extracted in a number of different ways that make multicomponent spectral (and hence chemical) comparisons between two samples easy to visualize and understand. In one approach, the infrared chemical images of two paint chips being compared side-by-side can be viewed as a "movie," in which each frame is an intensity map of the two samples at a given wavenumber (frequency) value. In another approach, the spectra (pixels) in the image files are classified into chemically similar groups, resulting in a "cluster" image that makes it possible to simultaneously compare all of the layers in two paint chips. These methods are applicable to other multicomponent samples, and also to other chemical imaging techniques.     

Examining the links between animal abuse and human violence

Empirical research has increasingly found evidence for the coexistence of animal abuse and various forms of interpersonal violence. Some researchers have even argued for a specific version of this relationship, namely, that individuals tend to move from violence toward animals, particularly in childhood, to subsequent violence toward humans. Others have suggested that the evidence for this graduation or progression hypothesis is weak and inconsistent, and that an approach to animal abuse that focuses on the link is misguided. This article begins by reviewing the research on the connections between animal abuse and interhuman violence. Then it critically assesses the evidence for and against the link, and discusses the issues and challenges facing future research in this area.     

Assistive technology as support for the exercise of legal capacity

Exercising legal capacity refers to engaging in legal transactions and relationships and is essential for the full inclusion of people with disabilities in society. The United Nations Convention on the Rights of Persons with Disabilities has enumerated the right to legal capacity on an equal basis and has created a state obligation to provide access to support for the exercise of legal capacity. This article examines the use of assistive devices as support for decision-making in exercising legal capacity for individuals with physical and cognitive impairments; for example, the use of voice recognition programmes, screen readers, and screen enlargement applications to support people with mobility and sensory impairments to use online portals essential for legal actions such as banking. It also discusses the experimental use of cognitive assistance, including computer or electrical assistive devices, to facilitate communication for people with cognitive impairments including those with no external signs of consciousness. It highlights the diversity of options for ‘support for the exercise of legal capacity’ showing how they can assist people with various disabilities. Finally, the article examines the boundaries of the state obligation to provide such support, including issues of practical implementation and resource allocation.     

The Politics of Memory/Errinerungspolitik and the Use and Propriety of Law in the Process of Memory Construction

The post-Second World War trial for the crime against humanity from the start assumed pedagogical proportions, with the tribunals involved conscious that their legal verdicts would represent historical pronouncement and national values. The newly defined crime has been asked to institutionalize far more than the traditional task of adjudicating the guilt or innocence of the defendant. The trials themselves are meant to define the past, create and crystallize national memory, and illuminate the foundations of the future. I suggest that, by placing a burden on law that it is not designed to bear,we risk deforming law and legal principle. We risk creating an edifice that will not be equal to the task of memory, that will trivialize the memory it seeks to establish and fortify and, worst of all, that may betray law itself by subverting it from within. This revised version was published online in July 2006 with corrections to the Cover Date.     

Separated Children: A Comparison of the Treatment of Separated Child Refugees Entering Australia and Canada

Separated children are in a uniquely vulnerable situation. Notonly are they in fear of persecution but they have been separatedfrom their families. They are seeking multifaceted protections.Such children need a country to protect them from further persecution,a caregiver to nurture them and fulfil the family role and asociety that will foster their social and intellectual growth.This article analyses the treatment of separated child refugeesin the context of international human rights law as it relatesto children and from the viewpoint of domestic immigration law.The article bases this analysis on a comparison of the treatmentof separated child refugees in Australia and Canada. The fundamentalprinciple of the International Convention on the Rights of theChild is that member states should act in the child's best interests.This principle has two important aspects, firstly, that detentionof children should only be used as a last resort and, secondly,that child refugees should enjoy the right to seek asylum. Thearticle examines the domestic law of both Australia and Canadawith a view to determining how these two aspects are appliedto unaccompanied children.     

Classification of firing pin impressions using HOG-SVM

Crimes, such as robbery and murder, often involve firearms. In order to assist with the investigation into the crime, firearm examiners are asked to determine whether cartridge cases found at a crime scene had been fired from a suspect's firearm. This examination is based on a comparison of the marks left on the surfaces of cartridge cases. Firing pin impressions can be one of the most commonly used of these marks. In this study, a total of nine Ruger model 10/22 semiautomatic rifles were used. Fifty cartridges were fired from each rifle. The cartridge cases were collected, and each firing pin impression was then cast and photographed using a comparison microscope. In this paper, we will describe how one may use a computer vision algorithm, the Histogram of Orientated Gradient (HOG), and a machine learning method, Support Vector Machines (SVMs), to classify images of firing pin impressions. Our method achieved a reasonably high accuracy at 93%. This can be used to associate a firearm with a cartridge case recovered from a scene. We also compared our method with other feature extraction algorithms. The comparison results showed that the HOG-SVM method had the highest performance in this classification task.
