Examining the Construct Validity of the Original and Revised JBS: A Cross-Validation of Sample and Method

Factor analysis is a statistical technique that can provide an understanding of construct validity. Previous research examining the factor structure of the Juror Bias Scale (JBS) has uncovered problems in the scale's assessment of the constructs of probability of commission (PC) and reasonable doubt (RD). We here reevaluate the scale's constructs to better our understanding of the pretrial biases involved in the juror decision-making process. Importantly, previous findings have been limited to college student samples and trial material that has involved rape evidence. This study examines the construct validity of the JBS in a sample of 617 jury-eligible adults drawn from the community, and the predictive validity of the JBS is examined across 3 distinct trial scenarios. The results parallel earlier findings, indicating that although RD is a tenable and useful construct affecting juror decision-making, PC may be a less relevant pretrial bias. We therefore suggest that future research emphasize alternative constructs, such as confidence and cynicism in the criminal justice system.     

Terrorism: The relevance of the rational choice model

Terrorism in general, and suicidal terrorism in particular, is popularly seen as “irrational,” but many economists and political scientists argue otherwise. This paper distinguishes three different senses of irrationality: unresponsiveness to incentives, deviation from narrow self-interest, and failure of rational expectations. It concludes that an intermediate position on the rationality of terrorism is appropriate. The typical terrorist sympathizer deviates only slightly from homo economicus. But active terrorists arguably stray from narrow self-interest and rational expectations, and suicidal terrorists probably violate both. Deterrence remains a viable anti-terrorism strategy, but deviations from rational expectations increase the potential of persuasion and appeasement.     

Physical and chemical evidence remaining after the explosion of large improvised bombs. Part 1: firings of ammonium nitrate/sugar and urea nitrate

Recent criminal acts in the United Kingdom, United States and other countries have demonstrated the dangers to public safety from the criminal use of improvised explosives on a large scale. Four sets of trials were carried out over four years, partly in collaboration with the United States Federal Bureau of Investigation, involving the firing of large bombs, mostly fertilizer based. The principal objectives of the firings were to measure the physical effects of the explosions upon objects representative of those that would be found at a real bomb scene and to recover any chemical traces deposited on these objects. The results are intended for use as an aid in determining the approximate size and type of an explosive employed in a terrorist attack. This paper describes the background behind the trials, the procedures for preparation of witness materials and charges, and the collection and analysis of physical and chemical evidence.     

Criminal justice and ethical ideology: an exploration of a loyalty-truthfulness dilemma

The notion of loyalty is well established in the criminological literature pertaining to ethics, ethical decision making, and ethical and ideological orientations. The present research addresses the topic of ethics and loyalty in an attempt to address three research questions germane to these areas within criminal justice and criminology. Using two samples equivalent in characteristics other than academic major, this research examines: (1) what impact gender, college major, and the ethical perspective of the observer and the nature of the actor’s action have upon the observer’s attitude toward the action (specific act of deception/truth); (2) what impact gender, college major, and the ethical perspective of the observer and the nature of the actor’s action have upon the observer’s perception of the social attractiveness of the deceiver; and (3) what impact gender, college major, the ethical perspective of the observer, and the nature of the actor’s action have upon the observer’s perception of the task attractiveness of the deceiver. Using a vignette design in this exploratory research, attempts are made to shed light on the impact of gender, major (criminal justice v. others), and ethical orientation on perceptions of an actor confronted with an ethical dilemma of loyalty versus disloyalty involving deception.     

The Politics of Palliative Care and the Ethical Boundaries of Medicine: Gonzales v. Oregon as a Cautionary Tale

The U.S. Supreme Court's 6-decision in Gonzales v. Oregon is the latest defeat for the Bush administration in its sustained attack on Oregon's physician-assisted suicide law. Both the majority opinion and the major dissent in Oregon provide an opportunity to assess the dangers inherent in allowing a political agenda that emphasizes the sanctity of life and minimizes professional ethical obligations to overshadow quality patient care at the end of life.
