Accommodation to increased accuracy demands by the right and left hands

This study was designed to identify the phase of rapid aimed movements responsible for hand differences in motor skill, and to evaluate potential differences between the hands in accommodating to greater accuracy demands. In both experiments, an accelerometer mounted on a stylus allowed key changes in acceleration to be used to partition the movement into phases. In Experiment 1, slower left hand movement times were attributable primarily to a terminal homing-in phase, especially as target size decreased. Since error rates varied as a function of hand and target size, speed-accuracy trade-offs may have occurred. Experiment 2 rigidly controlled error rate and confirmed the major hand difference to occur in the latter phase of the movement where error correction is presumed. Although less pronounced, adjustments were made in the earlier movement phases as well. Accommodation to greater accuracy demands involved moving the stylus closer to the target before decelerating to engage in error correction. This adjustment to gain enhanced precision was more pronounced in the left hand.     

Emotional face recognition in autism and in cerebral visual impairments: In search for specificity

Autism spectrum disorder (ASD) is characterized by difficulties in the social domain, but also by hyper- and hypo-reactivity. Atypical visual behaviours and processing have often been observed. Nevertheless, several similar signs are also identified in other clinical conditions including cerebral visual impairments (CVI). In the present study, we investigated emotional face categorization in groups of children with ASD and CVI by comparing each group to typically developing individuals (TD) in two tasks. Stimuli were either non-filtered or filtered by low- and high-spatial frequencies (LSF and HSF). All participants completed the autism spectrum quotient score (AQ) and a complete neurovisual evaluation. The results show that while both clinical groups presented difficulties in the emotional face recognition tasks and atypical processing of filtered stimuli, they did not differ from one another. Additionally, autistic traits were observed in the CVI group and symmetrically, some visual disturbances were present in the ASD group as measured via the AQ score and a neurovisual evaluation, respectively. The present study suggests the relevance of comparing ASD to CVI by showing that emotional face categorization difficulties should not be solely considered as autism-specific but merit investigation for potential dysfunction of the visual processing neural network. These results are of interest in both clinical and research perspectives, indicating that systematic visual examination is warranted for individuals with ASD.

Age-related differences in collision detection during deceleration

Observers were presented with displays simulating a 3-D environment with obstacles in the path of motion. During the trial, observer motion decelerated at a constant rate and was followed by a blackout prior to the end of the display. On some trials the rate of deceleration resulted in stopping before the collision, whereas on other trials the rate of deceleration resulted in a collision with the obstacles. The observer's task was to detect which trials simulated an impending collision. Proportion of collision judgments was greater for older as compared with younger observers when a collision was not simulated. Older observers showed less sensitivity to detect collisions than younger observers did, particularly at high speeds. The age-dependent results are discussed in terms of analyses based on tau and constant deceleration. The results suggest that increased accident rates for older drivers may be due to an inability to detect collisions at high speeds.     

Speed, size, and edge-rate information for the detection of collision events

In the present study an alternative analysis to tau was considered that was based on perceived speed and size and that assumed constant deceleration for the detection of collision events. Observers were presented with displays simulating a 3-D environment with obstacles in the path of observer motion. During the trial, observer motion decelerated at a constant rate and was followed by a blackout prior to the end of the display. Observers had to detect which trials resulted in a collision. The results indicate that collision detection varied as a function of the size of the obstacles, observer speed, and edge rate--findings not predicted by an analysis of tau. The results suggest that observers use an analysis based on speed and size information. A model that assumes constant deceleration is proposed for braking control.     

Title VII Sex and Race Discrimination Litigation Settlements as Opportunities for Organizational Change

Purpose

This study investigated how frequently and under what circumstances Title VII lawsuit settlements resulted in mandates for substantive organizational change in HR policies and practices that, according to social science research, are likely to move beyond mere pro forma compliance to foster greater inclusion and equality.

Design/Methodology/Approach

502 consent decrees settling Title VII sex and race discrimination lawsuits in 200–2008 were collected, coded, and analyzed. Multinomial logistic regression was used. Sociological theories of organizational change and of the relationship between law and organizations informed the study.

Findings

48 % of the consent decrees examined specified no meaningful substantive changes; 31 % required formalization of personnel decision-making remedies; 21 % required more innovative measures. Certified class actions, other non-individual lawsuits, lawsuits filed in more liberal Federal District Courts, and public sector employer predicted more substantive remedies for organizational change in organizations’ EEO policies and practices, all else being equal. Single plaintiffs and a conservative District Court legal environment predicted a greater likelihood of pro forma only remedies.

Implications

Discrimination lawsuit settlements are a potential impetus for improved diversity management policies.

Originality/Value

Consent decrees are an unusually direct and potentially powerful mechanism under Title VII for employment discrimination lawsuits to mandate substantive organizational change. Whereas a few studies have discussed a very small number of high-profile settlements, this is the first systematic examination of the programmatic mandates in consent decrees and how they vary.     

UNDERSTANDING THROUGH APPROPRIATION IN INTERRELIGIOUS DIALOGUE ON ETHICS

In today's globalized world, we need to communicate values clearly and constructively across cultures and religions to avoid misunderstanding and conflict and to find shared solutions to the issues affecting human communities across the world. This communication is not easy to implement and requires a considerable amount of commitment and empathy. To be effective, intercultural and interreligious dialogues on ethics demand, first of all, an accommodation of different epistemologies coupled with a sincere respect for their richness and internal coherence. Furthermore, our values are so closely rooted in our identity that expressing them becomes a cultural act—even an act of faith in the case of interreligious dialogue. In this paper, I argue that we need to reiterate or embrace this act of faith in the other's values if we are to properly understand them. How is this possible? The answer calls for a theoretical discussion of the hermeneutics of interreligious dialogue. When applied to intercultural and interreligious dialogues, I contend that the theory of hermeneutics needs a specific epistemological dimension—namely that of “appropriation”—that entails that we borrow the other's epistemological outlook, adopt the other's ad hoc modes of communication or transmission of values, and integrate the other's values into the constellation of our sources of meaning.     

Evidence-Based Medicine: A Genealogy of the Dominant Science of Medical Education

Debates about how knowledge is made and valued in evidence-based medicine (EBM) have yet to understand what discursive, social, and historical conditions allowed the EBM approach to stabilize and proliferate across western medical education. This paper uses a genealogical approach to examine the epistemological tensions that emerged as a result of various problematizations of uncertainty in medical practice. I explain how the problematization of uncertainty in the literature and the contingency of specific social, political, economic, and historical relations allowed the EBM approach to become a programmatic and pedagogical focus of the Faculty of Medicine at McMaster University and beyond.
