what helps and hinders workers in managing change

This research responds to calls for increased understanding of workers' experiences of their work and work contexts. Informed by positive psychology, this study focused on a seldom‐studied subset of working individuals who self‐identified as doing well with change affecting their work and on strategies that helped or hindered them in doing well, factors that would have helped, and their experiences of change within the context of volatile and changing work situations. Using the enhanced critical incident technique methodology, the authors extracted 790 incidents from 45 participant interviews. These data were organized into the following 10 categories: support from friends and family, support from colleagues, support from professionals, personal attitudes/traits/emotional set, self‐care, internal framework and boundaries, taking action, skill/role competence, management style and work environment, and personal life changes/issues. The implications of these categories for research, theory, practice, and organizations are discussed.     

“Just one animal among many?” Existential phenomenology,ethics, and stem cell research

Stem cell research and associated or derivative biotechnologies are proceeding at a pace that has left bioethics behind as a discipline that is more or less reactionary to their developments. Further, much of the available ethical deliberation remains determined by the conceptual framework of late modern metaphysics and the correlative ethical theories of utilitarianism and deontology. Lacking, to any meaningful extent, is a sustained engagement with ontological and epistemological critiques, such as with “postmodern” thinking like that of Heidegger’s existential phenomenology. Some basic “Heideggerian” conceptual strategies are reviewed here as a way of remedying this deficiency and adding to ethical deliberation about current stem cell research practices.     

Applying metaphors from physics to career/life issues

This article is based on a plenary address given at the 9th Annual Alberta Regional Consultation for Career Development (“Building Tomorrow Today”) in Edmonton, Alberta, Canada. The objective of the Consultation is to encourage the development of better links among practitioners and to provide a forum for the discussion of issues involved in community‐based employment services. In this article, the author summarizes and applies some of the major concepts in his latest book, The Physics of Living.     

Interactive effects of cumulative lifetime traumatic brain injuries and combat exposure on posttraumatic stress among deployed military personnel

Growing research links Traumatic Brain Injury (TBI) with greater posttraumatic stress disorder (PTSD) symptoms. Much of this research has focused on the influence of the presence or severity of a single TBI while neglecting the potential cumulative effects of multiple TBIs incurred across an individual’s lifetime on combat-related PTSD. The present study addressed this gap using a sample of 157 military service members and 4 civilian contractors who underwent structured TBI interviews at a military hospital in Iraq and completed the Combat Experiences Scale (CES) and Posttraumatic Checklist – Military (PCL-M). Results indicated that a greater number of lifetime TBIs were associated with greater PTSD symptoms when accounting for the presence and severity of a recent, deployment-related TBI. Additionally, a significant interaction of number of lifetime TBIs and combat exposure emerged, indicating that exposure to combat yielded greater PTSD symptoms among those with multiple lifetime TBIs compared to those with one or zero lifetime TBIs. These data suggest that incurring multiple TBIs may amplify the link between combat exposure and PTSD and underscore the need to screen for lifetime TBI history.     

The discriminability of smooth stereoscopic surfaces.

In this study the sensitivity of human vision to the smoothness of stereoscopic surface structure was investigated. In experiments 1 and 2 random-dot stereograms were used to evaluate the discrimination of smooth versus 'noisy' sinusoidal surfaces differing in the percentages of points on a single smooth surface. Fully coherent smooth surfaces were found to be much more discriminable than other less smooth randomly perturbed surfaces. In experiment 3 the discrimination between discontinuous triangle-wave surfaces and similarly shaped smoothly curved surfaces obtained from the addition of the fundamental and the third harmonic of the corresponding triangle-wave surface was evaluated. The triangle-wave surfaces were found to be more accurately discriminated from the smoothly curved surfaces than would be predicted from the detectability of the difference in their Fourier power spectra. This superior discriminability was attributed to differences between the curvature and/or discontinuity of the two surfaces. In experiment 3 the effects of incoherent 'noise' points on the discrimination between the two surface types were also evaluated. These randomly positioned noise points had a relatively small effect on the discrimination between the two surfaces. In general, the results of these experiments indicate that smooth surfaces are salient for stereopsis and that isolated local violations of smoothness are highly discriminable.
