Suspects,Lies, and Videotape: An Analysis of Authentic High-Stake Liars

This study is one of the very few, and the most extensive to date, which has examined deceptive behavior in a real-life, high-stakes setting. The behavior of 16 suspects in their police interviews has been analyzed. Clips of video footage have been selected where other sources (reliable witness statements and forensic evidence) provide evidence that the suspect lied or told the truth. Truthful and deceptive behaviors were compared. The suspects blinked less frequently and made longer pauses during deceptive clips than during truthful clips. Eye contact was maintained equally for deceptive and truthful clips. These findings negate the popular belief amongst both laypersons and professional lie detectors (such as the police) that liars behave nervously by fidgeting and avoiding eye contact. However, large individual differences were present.     

Criminal psychological profiling of serial arson crimes

The practice of criminal psychological profiling is frequently cited as being applicable to serial arson crimes. Despite this claim, there does not appear to be any empirical research that examines serial arson offence behaviors in the context of profiling. This study seeks to develop an empirical model of serial arsonist behaviors that can be systematically associated with probable offender characteristics. Analysis has produced a model of offence behaviors that identify four discrete behavior patterns, all of which share a constellation of common nondiscriminatory behaviors. The inherent behavioral themes of each of these patterns are explored with discussion of their broader implications for our understanding of serial arson and directions for future research.     

The interplay between economic and political logics: path dependency in health care in England

The purpose of this article is to use the ideas of path dependency to understand why policies implemented by governments for health care in England were and are suboptimal in terms of the control of total costs, the equitable distribution of hospital services, and efficiency in delivery. We do this by relating the economic logic of achieving these objectives to the political logic of a state-hierarchical system in which ministers are accountable for the effects of policies and doctors largely decide the supply and demand of health care. The initial policy path of the National Health Service (NHS) controlled costs but lacked systems to achieve equity and efficiency in the funding of hospitals. Policies were introduced to achieve equity, but not efficiency, in the 1970s. The Thatcher government sought efficiency through a budgetary squeeze in the 1980s, which culminated in the NHS funding crisis of 1987 - 1988. The result was the policies of the NHS internal market, which promised efficiency by introducing a purchaser-provider split and a system of provider competition in which money would follow the patient. These promises justified an injection of extra funds for three years, but only a pallid model of the internal market was implemented. The Blair government abandoned the rhetoric of competition but maintained the purchaser-provider split and continued to constrain total NHS costs, which resulted in the funding crisis of 1998 - 1999. Current policies are to substantially increase spending on health care and reintroduce a system of provider competition in which money will follow the patient.     

The evaluation of the extent of transporting or "tracking" an identifiable ignitable liquid (gasoline) throughout fire scenes during the investigative process

Tests have determined that boots or shoes of individuals at a fire scene do not transport sufficient contaminants ("tracking") through the fire scene to produce a positive laboratory result for the presence of gasoline in a fire scene that was not present at the time of the fire. Questions about the validity of forensic laboratory results have been raised on the basis that low-level gasoline residues detected in the laboratory samples could have been the result of transporting the residue by footwear contaminated from the fire scene ("tracking"). The data collected in this study establish that "tracking" does not lead to false-positive laboratory results. Canines trained and experienced in the detection of trace ignitable liquid residues were also utilized in this study. The canine results confirmed that properly trained canines show a higher sensitivity than do standard ASTM laboratory techniques for fire debris analysis. In a few cases, canines responded to contamination, but laboratory testing (which is the definitive indicator) did not produce positive results.     

Containing Land Grabs: a misguided response to rural conflicts over land

To a certain extent, a more stringent regime for requisition of rural land may help protect the interests of peasants. There is, however, a hierarchy of income opportunity in the countryside as a result of diversification of rural economic structure in reform China. The varying degree of land dependence renders a contrasting calculation on the value of land lease among Chinese peasants. For peasants in the more prosperous regions, the conflicts are primarily triggered by their exclusion from direct engagement in the land market and deprivation of the chance to maximise potential gain that fuels the growing tension in the countryside. A more direct response to this fundamental cause, however, requires audacious moves by the Party leadership venturing into zones of political taboo.     

New paradigms in researching police use of firearms

In the current climate of increasing violence against the police, the use of force by police officers has been the focus of much dabate, ranging from the use of non lethal incapacitant sprays to the use of lethal force^I. We review literature concerning the use of lethal force by police officers, evaluate its utility for operational contexts, consider its implications for training and propose that new technological devices can revolutionise the identification of crucial variables.     

The Effect of a Standard to Improve Person Descriptions by Children

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger and were then later asked to describe and answer various questions about that person using a third-person standard/comparison. Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where female - did have a significant effect on the recall ability of male participants.
