Do overall dimension ratings from assessment centres show external construct-related validity?

ABSTRACT

There have been repeated calls for an external construct validation approach to advance our understanding of the construct-related validity of assessment centre dimension ratings beyond existing internal construct-related validity findings. Following an external construct validation approach, we examined whether linking assessment centre overall dimension ratings to ratings of the same dimensions that stem from sources external to the assessment centre provides evidence for construct-related validity of assessment centre ratings. We used data from one laboratory assessment centre sample and two field samples. External ratings of the same dimensions stemmed from assessees, assessees’ supervisors, and customers. Results converged across all three samples and showed that different dimension-same source correlations within the assessment centres were larger than same dimension-different source correlations. Moreover, confirmatory factor analyses revealed source factors but no dimension factors in the latent factor structure of overall dimension ratings from the assessment centre and from external sources. Hence, consistent results across the three samples provide no support that assessment centre overall dimension ratings and ratings of the same dimensions from other sources can be attributed to dimension factors. This questions arguments that assessment centre overall dimension ratings should have construct-related validity.     

The Bishop and his/her Eucharistic Community: A Critique of Jean–Luc Marion's Eucharistic Hermeneutic

In the essay the hermeneutical views of Jean–Luc Marion, as they are expressed in his God without Being: Hors–Texte in relationship with the Eucharist and the story of Luke 24, are presented and critically assessed. The criticisms registered touch in the first place upon the concept of in persona Christi , which concerns the relation between the celebrant and Christ. Furthermore, the issue of the relationship between the eucharistic minister and his (or her) community and thereby the hermeneutical function of the Eucharist as a celebration of the whole community is discussed in dialogue with Marion's views.     

Understanding the link between work engagement and affective organisational commitment: The moderating effect of role stress

This study aimed to explore the moderating effect of role ambiguity and role conflict on the relationship between work engagement and affective organisational commitment. Using convenience sampling, a final sample of 179 IT-specialists of services companies in southern Spain was obtained. Moderation analyses were performed using the hierarchical regressions and bootstrapping method (Bias-Corrected confidence intervals). Results showed that work engagement was positively related to affective commitment while role ambiguity and role conflict were negatively related to it. However, only role conflict moderated the relationship between work engagement and affective commitment. That is, at high levels of role conflict, IT-specialists perceiving higher levels of work engagement reported lower levels of affective commitment. This study highlights the hindrance effect of role conflict on one of the most important consequences of work engagement: affective commitment with the organisation. An adequate definition of role and positions could help to reduce the levels of role conflict, increasing the emotional bond to the organisation.     

The capacity for selective concentration on color versus form of consonants

The concept of active exclusion or inhibition of some stimuli while focusing on others has been largely ignored or rejected in recent work in the field of attention. As part of an ongoing series of studies involving five posthypnotically cued levels of mental concentration, it was possible to test the capacity for active blurring of one stimulus attribute (form) while simultaneously perceiving another attribute (color) accurately. In lowered concentration conditions three highly trained hypnotic Ss were dramatically successful in blurring the form and thereby impairing identification of colored consonants flashed tachistoscopically at speeds ranging from 300 msec down to 50 msec—without any concomitant loss in accuracy of identification of the color in which the letter was printed. Among a supplemental series of control experiments, it was further demonstrated that the active inhibitory process can be reversed so as to act upon color but not form; and that the Ss were unable to duplicate these feats in the waking state without benefit of posthypnotic programming. A theoretical interpretation of the findings, in terms of a conceptual model of the mind, is offered.     

Method of Suicide in the Mentally Ill: A National Clinical Survey

Comparisons of psychiatric patients who die by suicide using different methods are scarce. We aimed to establish the methods of suicide used by those who are currently or have recently been in contact with mental health services in England and Wales (N = 6,203), and describe the social and clinical characteristics of suicides by different methods. We found that hanging, self‐poisoning, and jumping (from a height or in front of a moving vehicle) were the most common methods of suicide, accounting for 79% of all deaths. The implications of these and other findings are discussed.
