From marine ecology to crime analysis: Improving the detection of serial sexual offences using a taxonomic similarity measure

Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure—taxonomic similarity (Δ_s), recently developed in marine ecology—to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). Δ_s considers progressively higher‐level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific offence behaviours classified hierarchically. The behaviours are taken from 16 sexual offences by seven juveniles where each offender committed two or more offences. We demonstrate that both Jaccard and Δ_s show linked offences to be significantly more similar than unlinked offences. With up to 20% of the specific behaviours removed in simulations, Δ_s is equally or more effective at distinguishing linked offences than where Jaccard uses a full data set. Moreover, Δ_s retains significant difference between linked and unlinked pairs, with up to 50% of the specific behaviours removed. As police decision‐making often depends upon incomplete data, Δ_s has clear advantages and its application may extend to other crime types. Copyright © 2007 John Wiley & Sons, Ltd.     

THE PRESENT STATE OF THE COMPARATIVE STUDY OF RELIGIOUS ETHICS: An Update

A survey of developments over the last forty years suggests that little progress has been made in the development of comparative religious ethics as a discipline. While authors working in this field have produced a number of interesting works, the field lacks structure, including an agreement on the basic purpose, terms, and approaches by which contributions may be evaluated as better or worse. I provide an account of this history, suggesting that a way forward will involve marrying ethicists' interest in arguments with close attention to the more and less formal structures by which groups of people organize the giving and taking of reasons.     

Effects of task difficulty on use of advice

Although prior studies have found that people generally underweight advice from others, such discounting of advice is not universal. Two studies examined the impact of task difficulty on the use of advice. In both studies, the strategy participants used to weigh advice varied with task difficulty even when it should not have. In particular, the results show that people tend to overweight advice on difficult tasks and underweight advice on easy tasks. This pattern held regardless of whether advice was automatically provided or whether people had to seek it out. The paper discusses implications for the circumstances under which people will be open to influence by advisors. Copyright © 2006 John Wiley & Sons, Ltd.     

A RESPONSE TO DAVID HOLLENBACH AND SOHAIL H. HASHMI

Irene Oh affirms that religious freedom, faith, and reason, as David Hollenbach suggests, are subject matters that offer promising platforms for interreligious dialogue between Christians and Muslims. The need for cross‐cultural understanding is imperative especially given the current political climate, in which world leaders can easily exacerbate existing tensions through the misapplication of such terms. Sohail H. Hashmi addresses the need to discuss women's rights as part of a larger discussion on human rights in Islam. Oh concurs and notes that Sayyid Qutb's remarks on women in the United States serve as a starting point for clarifying women's agency in Islam.     

COMMENTS ON SIX RESPONSES TO DEMOCRACY AND TRADITION

This paper is a rejoinder to papers by Sabina Lovibond, Nicholas Wolterstorff, Sumner B. Twiss, G. Scott Davis, M. Cathleen Kaveny, and John Kelsay on the author's recent book Democracy and Tradition. The argument covers a host of topics, ranging from epistemology and methodology to human rights, the common law, and Islamic ethics.     

Philosophy and Cross-Cultural Conversation: Some Comments on the Project of Comparative Philosophy

This paper seeks to highlight the East-West asymmetry in philosophical exchanges. It draws attention to the absence of Eastern thought in the curriculum of philosophy in the West and suggests that cliches and stereotypes about cultures in general and thought-traditions in particular are perpetuated in this manner. The aim of the paper is to encourage 'cross-cultural conversation' among philosophers. A critical review of the project of 'comparative philosophy' is made to disclose the fact that despite the difficulties of such an endeavor, it is an attempt to bring thought-traditions together and is thereby useful for promoting intercultural understanding.     

Optimism and Revolt of the Oppressed: A Comparison of Two Polish Jewish Ghettos of World War II

One World War II Jewish ghetto that revolted, the Warsaw Ghetto, is compared to one that did not, the Lodz Ghetto, in order to examine the causes of violent resistance. This structured focused comparative method (George, 1979) illuminates problems with previous explanations for revolt and nonrevolt in Jewish ghettos and suggest psychological variables that might have led to or precluded organized violence. Specifically, it appears that these two ghettos differed in their perceptions about their future. The residents of the Warsaw Ghetto believed they had no hope of survival while residents of the Lodz Ghetto remained optimistic. These differing perceptions seem to have led to the different outcomes. Possible causes of these percetpions are also discussed.     

Further remarks on the role of cognition in the comparative analysis of behavior

Recent interest in comparative psychology has stimulated much research and debate concerning cognitive processes in animal behavior. The present paper relates to this general area by treating particular issues in the analysis of comparative cognition: specifically, how cognition is inferred from animal behavior; whether the postulation of intervening cognitive processes furthers our understanding of behavior; and how rival approaches help advance the science of behavior.
