Adaptation to optically-increased interocular separation under naturalistic viewing conditions

Mirror spectacles which enhance binocular disparity by optically doubling the normal separation between the eyes were used to create conditions of combined perceptual and oculomotor conflict. Apparent depth and distance, as well as tonic accommodation, tonic vergence, and accommodative-vergence gain (response AC/A ratio), were assessed immediately before and after a 30 min exposure period of naturalistic viewing with the spectacles. Wearing the spectacles produced an increase in tonic vergence, and perceptual aftereffects consisting of increased apparent distance and depth. The results indicate that oculomotor conflict associated with enhanced interocular separation may be resolved through adaptation of tonic vergence, rather than through alteration of accommodative-vergence gain. The results also demonstrate that perceptual conflict between disparity and multiple veridical depth cues does not necessarily produce adaptive modification of the relationship between binocular disparity and apparent depth.     

Professing Feminism: Feminist Academics and the Women's Movement

This article examines feminist academics'work in its social and political context, with the purpose of understanding the conditions which facilitate or impede the incorporation of a feminist perspective into college or university teaching. The discussion analyzes four basic contradictions which pervade feminist academic work: the contradictions (1) between feminist academics and their students, (2) between feminist academics and their disciplines, (3) between feminist academics and the institutional setting of their work, and (4) between feminist academics and feminists working in the larger women's community. The analysis of these contradictions focuses on the role of structured competition in shaping and constraining the ways in which feminist academics can do their work. The article ends with some brief suggestions concerning areas of needed action.

The Importance of Definitional and Temporal Issues in the Study of Resilience

Despite recent interest in the topic of resilience in organisations, much work is still needed to advance our understanding of this important area of inquiry. With this in mind, the authors argue that the study of resilience would benefit from (1) greater definitional clarity and (2) explicit inclusion of temporal issues in theoretical conceptualisations of resilience. Based on a systematic review of the literature, we advocate for a concise definition of resilience, along with a heuristic framework intended to meaningfully categorise the various elements, features, and experiences implicated by the concept of resilience, including (a) adversity triggers, (b) resilience outcomes, (c) resilience mechanisms, and (d) resilience promoting factors. This is followed by a discussion of temporal issues in relation to each of the four categories above. Various propositions and recommendations for future research are also presented.
