Relevant and Effective Theological Education in the Context of Twenty‐First Century South Asia

This essay considers Christian theological education in South Asia highlighting pertinent issues in pedagogical content, form, method, and praxis. Debunking the notion of students as “empty bottles” to be filled, and criticizing the top‐down model of education, the paper argues that theological education is an ongoing and interactive process in which students and teachers are participants who share and reflect upon each other's faith and socio‐cultural experiences. Participants reject, test, negotiate, and choose – while remaining open to the variety that is embodied in different human experiences. The paper stresses the relationship between the theological college and the church and calls for mutual responsibility, respect, and accountability. In an increasingly communal and fundamentalist atmosphere that poses a threat to multi‐culturalism, the role of the laity in shaping theological education is highlighted and public debate is encouraged. The paper calls for interactive and dialogic learning. A version of this paper was published in Ministerial Formation 100 (2003): 5–16.     

Leader-Member Exchange and Transformational Leadership: An Empirical Examination of Innovative Behaviors in Leader-Member Dyads

This paper evoked leader-member exchange (LMX) and transformational leadership theories to explain innovative behavior in leader-member dyads. Data from 225 leader-member dyads in a Fortune 500 manufacturing plant found exchange quality to be positively related to follower autonomy, leader support of followers, and follower commitment to the organization. Further, followers who were supported by their leaders and who were committed to the organization were more likely to be innovative. Also, exchange quality was directly related to innovative behaviors. Contrary to expectations, transformational leadership was negatively related to innovative behaviors of followers.     

Outing and Virtue Ethics

The paper argues that the two dominant approaches towards the moral issues surrounding outing are too weak to handle the latter's complexity and would benefit from being made part of a broader and richer framework, namely, that of virtue ethics. One dominant approach begins by arguing that people do not have the right to privacy in matters of sexual orientation (not behaviour), and so outing gay people does not violate such a right. It continues by arguing that living a dignified life requires the agent to refuse to keep secret the gay sexual orientation of others. The second dominant approach, opposed to the first, argues that gay people have a right to the privacy of sexual orientation, and so outing them is prima facie wrong. Both approaches, the paper argues, are too weak to handle the complexity of outing: the first suffers from emphasizing only one subset of the virtues (dignity, pride, and so on), while the second is too weak to explain fully why in some cases outing is permissible. Virtue ethics is a much richer framework from which to address the complexity of outing.     

Functional neuroanatomy of gesture–speech integration in children varies with individual differences in gesture processing

Gesture is an integral part of children's communicative repertoire. However, little is known about the neurobiology of speech and gesture integration in the developing brain. We investigated how 8‐ to 10‐year‐old children processed gesture that was essential to understanding a set of narratives. We asked whether the functional neuroanatomy of gesture–speech integration varies as a function of (1) the content of speech, and/or (2) individual differences in how gesture is processed. When gestures provided missing information not present in the speech (i.e., disambiguating gesture; e.g., “pet” + flapping palms = bird), the presence of gesture led to increased activity in inferior frontal gyri, the right middle temporal gyrus, and the left superior temporal gyrus, compared to when gesture provided redundant information (i.e., reinforcing gesture; e.g., “bird” + flapping palms = bird). This pattern of activation was found only in children who were able to successfully integrate gesture and speech behaviorally, as indicated by their performance on post‐test story comprehension questions. Children who did not glean meaning from gesture did not show differential activation across the two conditions. Our results suggest that the brain activation pattern for gesture–speech integration in children overlaps with—but is broader than—the pattern in adults performing the same task. Overall, our results provide a possible neurobiological mechanism that could underlie children's increasing ability to integrate gesture and speech over childhood, and account for individual differences in that integration.     

Uncertainty-dependent activity within the ventral striatum predicts task-related changes in response strategy

Recent neuroimaging work has demonstrated that the ventral striatum (VS) encodes confidence in perceptual decisions. However, it remains unclear whether perceptual uncertainty can signal the need to adapt behavior (such as by responding more cautiously) and whether such behavioral changes are related to uncertainty-dependent activity within the VS. Changes in response strategy have previously been observed following errors and are associated with both medial frontal cortex (MFC) and VS, two components of the performance-monitoring network. If uncertainty can elicit changes in response strategy (slowing), then one might hypothesize that these changes rely on the performance-monitoring network. In the present study, we investigated the link between perceptual uncertainty and task-related behavioral adaptations (response slowing and accuracy increases), as well as how such behavioral changes relate to uncertainty-dependent activity within MFC and VS. Our participants performed a two-choice perceptual decision-making task in which perceptual uncertainty was reported on each trial while behavioral and event-related functional magnetic resonance imaging data were collected. Analysis of the behavioral data revealed that uncertain (but correct) responses led to slowing on subsequent trials, a phenomenon that was positively correlated with increased accuracy. Critically, post-uncertainty slowing was negatively correlated with the VS activity elicited by uncertain responses. In agreement with previous reports, increases in MFC activation were observed for uncertain responses, although MFC activity was not correlated with post-uncertainty slowing. These results suggest that perceptual uncertainty can serve as a signal to adapt one’s response strategy and that such behavioral changes are closely tied to the VS, a key node in the performance-monitoring network.     

People vs God: The logic of ‘divine sovereignty' in Islamic democratic discourse

This paper aims at clarifying the role which the concept of 'divine sovereignty' plays in the discussions which are taking place among Islamic thinkers (and others) concerning the possibility of democracy in an Islamic context. It argues that 'sovereignty' has at least two meanings, one 'factual', the other 'normative'. The paper also argues that the second sense of 'sovereignty' allows us to construe talk of 'divine sovereignty' as an attempt by Islamic thinkers to go beyond the merely procedural views of democracy which focus on the familiar procedures of power contestation, election and accountability.     

Analysis of the role of associative inhibition in perceptual learning by means of the same-different task

In Experiment 1a, participants were exposed, over a series of trials, to separate presentations of 2 similar checkerboard stimuli, AX and BX (where X represents a common background). In one group, AX and BX were presented on alternating trials (intermixed), in another, they were presented in separate blocks of trials (blocked). The intermixed group performed to a higher standard than the blocked group on a same-different test. A superiority of intermixed over blocked exposure was also evident in a within-subject design (Experiment 1b) and when the test required discrimination between a preexposed stimulus and the background (e.g., AX vs. X), even if the background changed between preexposure and test (AY vs. Y) (Experiment 2). In Experiment 3, the intermixed/blocked effect was observed when, in preexposure, stimulus presentations were alternated with the background alone (e.g., AX/X). This suggests that the perceptual learning effect is not the consequence of inhibitory associations between unique features but to increased salience of those features. Experiment 4 confirmed this finding and also ruled out an account of the effect in terms of trial spacing.     

Scale of attentional focus in visual search

The effects of the spatial scale of attention on feature and conjunction search were examined in two experiments. Adult participants in three age groups—young, young-old, and old-old—were given precues of varying validity and precision in indicating the location of a target letter subsequently presented in a visual array. Systematic decreases in the size of a valid precue (toward the size of the target) progressively facilitated both feature and conjunction search, with a greater benefit accruing to conjunction search. Age-related slowing in conjunction search was mitigated by precise (small and valid) precues, presumably because they reduced the need for participants in the young-old group to focus and to shift attention. Nevertheless, this benefit was reduced in the old-old group. The effects of valid location precue size varied with cue-target stimulus onset asynchrony (SOA) in a manner that interacted with search difficulty: Effects of cue size developed more rapidly in feature search but more slowly in conjunction search. Finally, when precues were invalid for target location, search was faster with larger sized precues. Thus, in both easy feature search and hard conjunction search, the scale of visuospatial attention modulates the speed of visual search. Furthermore, when the SOA is sufficiently long for cue effects to develop, the ability to dynamically adjust the scale of visuospatial attention appears to decline in advanced age. These results go beyond current models in suggesting that visuospatial attention possesses two dynamic properties—shifting in space and varying in scale—that are deployed independently, depending on task demands.     

Do procedures really matter when rewards are more important? A Pakistani perspective on the effects of distributive and procedural justice on employee behaviors

Introduction

Researchers agree that procedural justice and distributive justice interact so that high procedural fairness reduces the negative consequences of distributive unfairness.

Cognitive deficits following coronary artery bypass grafting: prevalence, prognosis, and therapeutic strategies

There is increasing recognition that coronary artery bypass grafting (CABG) may be a risk factor for subtle cognitive decline although the presence and pattern of such decline has varied across studies. Cognitive deficits may present as short-term memory loss, executive dysfunction and psychomotor slowing. Although they are usually are not severe enough to meet criteria for mild cognitive impairment or vascular dementia, they lower quality of life and add to hospitalization and out-of-hospital costs. Proposed mechanisms include surgical-related trauma, genetic susceptibility (eg, apolipoprotein E4 allele), microembolization, other vascular or ischemic changes, and temperature during surgery. Depression and anxiety levels predict subjective perception of these deficits more than objective cognitive performance. Both nonpharmacologic (eg, emboli reduction, temperature, or glucose management) and pharmacologic (eg, dexanabinol, glypromate, nootropics) strategies to prevent post-CABG cognitive deficits are under investigation. Given the large numbers of subjects who may already have CABG associated cognitive deficits, clinical trials of agents being tested for Alzheimer's disease (eg, donepezil, rivastigmine, memantine, neramexane, ginkgo) may also be informative. The results of multicenter long-term outcome studies (with matched control groups) as well as ongoing treatment trials will more conclusively address some of these issues. These data emphasize the need for clinicians to monitor cognitive function before and after coronary bypass surgery, and to educate patients.
