An empirical estimate of the precision of likelihood ratios from a forensic-voice-comparison system

An acoustic-phonetic forensic-voice-comparison system was constructed using the time-averaged formant values of tokens of 61 male Chinese speakers' /i/, /e/, and /a/ monophthongs as input. Likelihood ratios were calculated using a multivariate kernel density formula. A separate set of likelihood ratios was calculated for each vowel phoneme, and these were then fused and calibrated using linear logistic regression. The system was tested via cross-validation. The validity and reliability of the results were assessed using the log-likelihood-ratio-cost function (C(llr), a measure of accuracy) and an empirical estimate of the credible interval for the likelihood ratios from different-speaker comparisons (a measure of precision). The credible interval was calculated on the basis of two independent pairs of samples for each different-speaker comparison pair.

Assortative Mating on Ideology Could Operate Through Olfactory Cues

Mates appear to assort on political attitudes more than any other social, behavioral, or physical trait, besides religion. Yet the process by which ideologically similar mates end up together remains ambiguous. Mates do not appear to consciously select one another based on ideology, nor does similarity result from convergence. Recently, several lines of inquiry have converged on the finding that olfactory processes have an important role in both political ideology and mate selection. Here we integrate extant studies of attraction, ideology, and olfaction and explore the possibility that assortation on political attitudes may result, in part, from greater attraction to the scent of those with shared ideology. We conduct a study in which individuals evaluated the body odor of unknown others, observing that individuals are more attracted to their ideological concomitants.     

Studying the Past: the Nature and Development of Legal History as an Academic Discipline

This article pursues two themes. First, it argues that there is a commonality between the general interest in the past, the interest of historians, and the interest of legal historians. Second, it shows that several ideas about the past commonly appear in all three contexts. In pursuing these themes, the article begins by reviewing the initial study of the past and the emergence of history and legal history in academia. It explores the various reasons why the early historians and later academic historians and legal historians studied the past and the different ways in which they used it. The article then pursues in more detail the development of Anglo-American legal history as a scholarly tradition. It identifies three types of academic legal history: classical, liberal, and critical, and discusses their natures and different uses of the past. Finally, the article explores the substantial legal history scholarship and its relevance to scholars who are not legal historians. The article concludes by stressing the importance of studying the legal past.
