Symmetry of receiver operating characteristic curves and Kullback–Leibler divergences between the signal and noise populations

It is shown that the symmetry of the receiver operating characteristic curve implies that the Kullback–Leibler divergences between the signal and noise populations are equal when the arguments are interchanged.     

Assessing Diagnostic Expertise of Counselors Using the Cochran–Weiss–Shanteau (CWS) Index

Counseling studies have shown that increasing experience is not always associated with better judgments. However, in such studies performance is assessed against external criteria, which may lack validity. The authors applied the Cochran–Weiss–Shanteau (CWS) index, which assesses the ability to consistently discriminate. Results showed that novice counselors performed almost on the same level as very experienced counselors. The authors thus replicated earlier findings with a novel approach: applying an internal coherence criterion.     

Barth and the Evangelicals – Engaging with Barth: Contemporary Evangelical Critiques – Edited by David Gibson and Daniel Strange

This review examines twelve conservative evangelical responses to David Gibson and Daniel Strange's Engaging with Barth. Witten in a charitable spirit that gives deference to Barth, the essayists remained uncomfortable with the prospect of rehabilitating Barth's radical neo‐orthodoxy for contemporary evangelical theology. In the article, I summarize the authors' critiques to Barth's exegetical, historical, and theological program, and locate their contributions pertaining to the reading of Barth's dogmatics. The review concludes with a possibility of interrogating the pneumatological‐underpinnings in Barth's theology as a constructive reworking of Barth's trinitarian theology for evangelical theology. There are ‘spaces’ for evangelicals to mine from the Barthian legacy, albeit via the medium of turning Barth's proposals on its head.     

Effects of gain—loss frames on satisfaction with self–other outcome-differences

This research concerned satisfaction with outcome-differences (advantageous inequity, equity, or disadvantageous inequity) as a function of the individual's gain or loss frame, other's gain or loss frame, the cooperative or noncooperative nature of the relationship, and their interactions. After reading a scenario, subjects rated on a satisfaction-dissatisfaction scale a series of outcome-pairs providing themselves and another party with outcomes. Consistent with Equity Theory, results showed that gain framed individuals found equity more pleasing than advantageous inequity, which in turn was preferred over disadvantageous inequity, but only when the decision making context was coopera- tive rather than noncooperative. In a noncooperative context, gain framed individuals were as pleased with equity as with advantageous inequity. Contrary to Equity Theory, but consistent with Prospect Theory, loss framed individuals were relatively insensitive to outcome-differences and the nature of the relationship. Results finally suggested that advantageous inequity was preferred less when the other party had a loss rather than gain frame, albeit only under cooperative circumstances.     

Evaluation of convergent and discriminant validity with multitrait–multimethod correlations

A procedure for evaluation of convergent and discriminant validity coefficients is outlined. The method yields interval estimates of these coefficients in a construct validation study conducted via the multitrait–multimethod approach, as well as permitting examination of their population relationships. The procedure is readily employed in behavioural research using the increasingly popular latent variable modelling methodology. The method is illustrated with a numerical example.     

Infant–mother and infant–father synchrony: The coregulation of positive arousal

To examine the coregulation of positive affect during mother–infant and father–infant interactions, 100 couples and their first‐born child were videotaped in face‐to‐face interactions. Parents' and infant's affective states were coded in one‐second frames, and synchrony was measured with time‐series analysis. The orientation, intensity, and temporal pattern of infant positive arousal were assessed. Synchrony between same‐gender parent–infant dyads was more optimal in terms of stronger lagged associations between parent and infant affect, more frequent mutual synchrony, and shorter lags to responsiveness. Infants' arousal during mother–infant interaction cycled between medium and low levels, and high positive affect appeared gradually and was embedded within a social episode. During father–child play, positive arousal was high, sudden, and organized in multiple peaks that appeared more frequently as play progressed. Mother–infant synchrony was linked to the partners' social orientation and was inversely related to maternal depression and infant negative emotionality. Father–child synchrony was related to the intensity of positive arousal and to father attachment security. Results contribute to research on the regulation of positive emotions and describe the unique modes of affective sharing that infants coconstruct with mother and father. ©2003 Michigan Association for Infant Mental Health.
