The Right to Trial by Jury

abstract Recently, the right to trial by jury has attracted a number of vociferous critics with deep reservations about the use of juries, most of whom are in favour of greatly restricting the use of juries with a minority desiring complete abolition. This article offers a justification for the continued use of jury trials. I shall critically examine the ability of juries to render just verdicts, judicial impartiality, and judicial transparency. My contention is that the judicial system that best satisfies these values is most preferable. Of course, these three values are not the only factors relevant for consideration. Empirical evidence demonstrates that juries foster both democratic participation and public legitimation of legal decisions regarding the most serious cases. Nevertheless, juries are costly and, therefore, economically less efficient than competing modes of trial. I do not argue that all human beings possess an inalienable legal right to be tried by a jury. However, it is my hope that this analysis will make clear what we might gainor lose when we propose jury reforms.     

From alpha to omega: A practical solution to the pervasive problem of internal consistency estimation

Coefficient alpha is the most popular measure of reliability (and certainly of internal consistency reliability) reported in psychological research. This is noteworthy given the numerous deficiencies of coefficient alpha documented in the psychometric literature. This mismatch between theory and practice appears to arise partly because users of psychological scales are unfamiliar with the psychometric literature on coefficient alpha and partly because alternatives to alpha are not widely known. We present a brief review of the psychometric literature on coefficient alpha, followed by a practical alternative in the form of coefficient omega. To facilitate the shift from alpha to omega, we also present a brief guide to the calculation of point and interval estimates of omega using a free, open source software environment.     

Interactions among emergent relations during equivalence class formation

The interactions among symmetry, transitivity, and equivalence tests during the formation of 3-member equivalence classes were studied with 14 college students. After training AB and BC, a test with BA, CB, AC, and CA was conducted concurrently. Failure led to serial testing with probes for CA equivalence, BA symmetry, CA equivalence, CB symmetry, CA equivalence, AC transitivity, and CA equivalence. For five subjects, equivalence tests were passed immediately once BA and CB symmetry as well as AC transitivity had been induced. Thus, symmetry and transitivity were precursors for successful performance on equivalence tests. The conjoint function of symmetry and transitivity was assessed with the equivalence probes. As the equivalence probes were passed immediately, the presence of symmetry alone and transitivity alone were sufficient for their conjoint function without additional intervention. For different subjects, transitivity alone and symmetry were induced either directly with BA, CB, or AC probes or indirectly with equivalence probes. Equivalence probes can also induce various combinations of symmetry and transitivity. Thus, different subjects formed classes in various patterns at different rates.     

Forensic voice discrimination by lay listeners: The effect of speech type and background noise on performance

In forensic settings, lay (nonexpert) listeners may be required to compare voice samples for identity. In two experiments we investigated the effect of background noise and variations in speaking style on performance. In each trial, participants heard two recordings, responded whether the voices belonged to the same person, and provided a confidence rating. In Experiment 1, the first recording featured read speech and the second featured read or spontaneous speech. Both recordings were presented in quiet, or with background noise. Accuracy was highest when recordings featured the same speaking style. In Experiment 2, background noise either occurred in the first or second recording. Accuracy was higher when it occurred in the second. The overall results reveal that both speaking style and background noise can disrupt accuracy. Although there is a relationship between confidence and accuracy in all conditions, it is variable. The forensic implications of these findings are discussed.     

In Search of Śiva: Mahādēviyakka's V&īraśaivism

Mahādēviyakka was a radical 12th century Karnataka saint of whom surprisingly little has been written. Considered the most poetic of the Vīra?aivas, her vacanas are characterized by their desperate searching for ?iva. I attempt to convey Mahādēvi's epistemology and its struggle to 'know' ?iva, necessitating a lifetime of searching for him; offer an interpretation of the innate presence of ?iva in the world and its consequences for epistemology; and explore the sense of tragic love inherent in devotional searching for ?iva. My primary goal is to offer a powerful and positive, yet critical, interpretation of Mahādēvi's beautiful prose on her relationship with ?iva.
