Organizational Creativity and Innovation in Relation to Psychological Well-Being and Organizational Factors

The two objectives of the research reported in this article were to investigate the relationship between organizational creativity and innovation and psychological well-being of employees, as well as the relationship between organizational factors and organizational creativity and innovation. Ninety-five employees working in a high-tech field of industry participated in the study. The relationships were tested in a LISREL model and the result showed a significant relationship between perceived organizational creativity and innovation and individual psychological well-being. Of the organizational factors included in the model, organizational climate and work resources were found to be significantly related to perceived creativity and innovation in the organization. Taken together, the results suggest that enhancing the conditions for creativity and innovation is beneficial for the individual in terms of better psychological well-being.     

Psychosocial correlates of immune status and disease progression in HIV-1 infected homosexual men: Review of preliminary findings,and commentary

Abstract

Behavioral factors may have an effect on the course of infection in HIV-1 infected individuals. These effects can be mediated by the immune system of the host, which, based on psychoneuroimmunologic findings, can be affected by some psychosocial factors. We present a short review of some putative psychoneuroimmunologic pathways and their possible implications for HIV-1 infected individuals. We next summarize the findings of recent psychoimmunological work with HIV-1 seropositives and discuss the methodological problems in studying the psychoneuroimmunologic aspects of HIV-1 infection. Psychoneuroimmunologic research in HIV-1 seropositives is a rapidly developing field, yielding contradictory findings so far, but which in the long run could provide important knowledge for psychoimmunologic interventions, targeted at improving or preserving immune status and retarding disease progression, as well as optimizing psychosocial functioning.     

Listening while talking: The retention of prose under articulatory suppression in relation to simultaneous interpreting

According to working memory theory (e.g., Baddeley & Logie, 1999) articulatory suppression (AS) prevents rehearsal in the articulatory loop of to be remembered material, which, in turn, has a disruptive effect on recall. Simultaneous interpreting is an activity where people routinely comprehend and maintain speech while articulating at the same time. We examined whether AS also affects retention when, as in interpreting, coherent text is to be remembered or meaningful and phonologically more complex material is articulated. In the first part of the study, participants listened to a set of stories, and were involved in traditional or complex AS. Also coherence of the texts was manipulated. We found that the effects of AS generalises to stories, that coherence influences recall and that both variables interact. In the second part, we related individual differences in retention under conditions of AS to simultaneous interpreting performance. The results are discussed in terms of the episodic buffer component (e.g., Baddeley, 2000).     

Personality Characteristics of BASE Jumpers

BASE jumping is an extreme sport, which is associated with significant risk of injury and death. We aimed to determine whether BASE jumpers have different personality characteristics to an age-matched, normal control population. An international population of BASE jumpers was examined using the Temperament and Character Inventory (TCI). Mean age was thirty-four years; fifty-nine (87%) jumpers were male; twenty-eight (41%) jumpers had sustained a significant injury. A substantial proportion of the BASE jumpers presented extremely low scores in the temperament measure of Harm Avoidance (p < 0.001); the extent of which has not been reported in any other population.     

Personal Growth Initiative and Mental Health: A Meta-Analysis

Personal growth initiative (PGI) is an individual's active and intentional desire to grow in personally important areas. In the past 20 years, a body of literature has emerged examining PGI's relationship to mental health. We conducted the first meta-analyses to synthesize this literature. Two meta-analyses examined the relationship between PGI total scores and distress (k = 22) and wellness (k = 37). Both average effect sizes were significant. We also examined the potential impact of nine moderators. The type of outcome assessed was a significant moderator for PGI and distress, and the PGI measure used was a significant moderator for PGI and wellness, accounting for 61% and 15% of the overall variance, respectively. Meta-analyses examining the relationship between the four PGI subscales (Readiness for Change, Planfulness, Using Resources, and Intentional Behavior) and distress (k = 4) and wellness (k = 7) yielded similar results to the total score analyses.     

Circular interpretation of regression coefficients

The interpretation of the effect of predictors in projected normal regression models is not straight-forward. The main aim of this paper is to make this interpretation easier such that these models can be employed more readily by social scientific researchers. We introduce three new measures: the slope at the inflection point (b_c), average slope (AS) and slope at mean (SAM) that help us assess the marginal effect of a predictor in a Bayesian projected normal regression model. The SAM or AS are preferably used in situations where the data for a specific predictor do not lie close to the inflection point of a circular regression curve. In this case b_c is an unstable and extrapolated effect. In addition, we outline how the projected normal regression model allows us to distinguish between an effect on the mean and spread of a circular outcome variable. We call these types of effects location and accuracy effects, respectively. The performance of the three new measures and of the methods to distinguish between location and accuracy effects is investigated in a simulation study. We conclude that the new measures and methods to distinguish between accuracy and location effects work well in situations with a clear location effect. In situations where the location effect is not clearly distinguishable from an accuracy effect not all measures work equally well and we recommend the use of the SAM.     

Transgenic inhibition of neuronal calcineurin activity in the forebrain facilitates fear conditioning, but inhibits the extinction of contextual fear memories

It is unclear whether protein phosphatases, which counteract the actions of protein kinases, play a beneficial role in the formation and extinction of previously acquired fear memories. In this study, we investigated the role of the calcium/calmodulin dependent phosphatase 2B, also known as calcineurin (CaN) in the formation of contextual fear memory and extinction of previously acquired contextual fear. We used a temporally regulated transgenic approach, that allowed us to selectively inhibit neuronal CaN activity in the forebrain either during conditioning or only during extinction training leaving the conditioning undisturbed. Reducing CaN activity through the expression of a CaN inhibitor facilitated contextual fear conditioning, while it impaired the extinction of previously formed contextual fear memory. These findings give the first genetic evidence that neuronal CaN plays an opposite role in the formation of contextual fear memories and the extinction of previously formed contextual fear memories.     

The Kosovar sponsoring experience in Northern Alberta

We examine the experiences of sponsors who assisted Kosovar refugees in Northern Alberta. Although the sponsors of the Kosovars did not provide basic financial support to the refugees, many found their role to be onerous, particularly in terms of emotional investment and demands on their time. They would have liked more opportunity to debrief and to have contact with other experienced sponsors. Some of the sponsors' initial expectations of the Kosovars were at odds with reality; conversely, many sponsors felt that the refugees had unrealistic expectations of them and of life in Canada. Recommendations are made for future sponsoring arrangements.
