Introduction

This introduction presents selected proceedings of a two‐day meeting on the regress problem, sponsored by the Netherlands Organization for Scientific Research (NWO) and hosted by Vanderbilt University in October 2013, along with other submitted essays. Three forms of research on the regress problem are distinguished: metatheoretical, developmental, and critical work.     

Parent–offspring conflict over mate choice: An experimental study in China

Both parents and offspring have evolved mating preferences that enable them to select mates and children-in-law to maximize their inclusive fitness. The theory of parent–offspring conflict predicts that preferences for potential mates may differ between parents and offspring: individuals are expected to value biological quality more in their own mates than in their offspring's mates and to value investment potential more in their offspring's mates than in their own mates. We tested this hypothesis in China using a naturalistic ‘marriage market’ where parents actively search for marital partners for their offspring. Parents gather at a public park to advertise the characteristics of their adult children, looking for a potential son or daughter-in-law. We presented 589 parents and young adults from the city of Kunming (Yunnan, China) with hypothetical mating candidates varying in their levels of income (proxy for investment potential) and physical attractiveness (proxy for biological quality). We found some evidence of a parent–offspring conflict over mate choice, but only in the case of daughters, who evaluated physical attractiveness as more important than parents. We also found an effect of the mating candidate's sex, as physical attractiveness was deemed more valuable in a female potential mate by parents and offspring alike.     

Evaluating health care work settings: A holistic conceptual framework

Abstract

After offering a systems perspective that considers a diversity of job-related and personal factors, we discuss the determinants and impacts of health care work climates and how staff morale and performance can influence the treatment milieu and quality of patient care. We also describe the physical features, organizational structure and policies, and suprapersonal and task factors that help to shape health care work climates. We then review research on the connections between work climate and staff morale and performance, the interplay of work climate factors, and the role of personal factors in these relationships. Finally, we orovide some ideas about how to improve health care work settings and focus on some promising new research directions.     

Perceived Perpetration During Traumatic Events: Clinical Suggestions From Experts in Prolonged Exposure Therapy

Prolonged exposure therapy (PE) is a treatment that has proven effectiveness in reducing the symptoms of posttraumatic stress disorder (PTSD) and related psychopathology. Providing PE to trauma survivors with PTSD, particularly related to combat trauma, often involves addressing guilt or shame related to their contextually appropriate use of violence and lethal force. In this paper, we present 4 clinical case vignettes in order to define the concept of perceived perpetration, and offer clinical suggestions for assessment and treatment with PE. Specifically, we examined issues such as identifying what type of traumatic events are appropriate for the use of PE, how to approach issues surrounding actions that could be perceived as perpetration, and attending to trauma-related guilt or shame.     

Cumulative trauma and midlife well-being in American women who served in Vietnam: effects of combat exposure and postdeployment social support

Background and Objectives: Research increasingly demonstrates that trauma exposure can have cumulative effects, yet much remains to be learned about effects of cumulative trauma, particularly regarding longer term adjustment. One such trauma, combat exposure, is insufficiently understood, especially for women, who are increasingly engaged in professional combat activities. Design: The study comprised a cross-sectional survey assessing multiple aspects of current well-being in women approximately 25 years after their service in Vietnam during the Vietnam War. Methods: Participants were 1374 women (78% military and 22% nonmilitary; mean age = 59.7). This study investigated the relations between three separate categories of trauma exposure (childhood, adulthood, and combat) and well-being and examined whether perceived social support at return from Vietnam moderated the association between combat exposure and well-being. Results: While both childhood and adulthood trauma exposure related to midlife well-being, combat exposure still uniquely predicted outcomes. Further, postdeployment perceived social support moderated the association of combat and well-being: recollected higher perceived social support at homecoming buffered participants from the links between combat exposure and well-being. Conclusions: These results may have important implications for interventions to reduce the impact of traumatic experiences, particularly in light of the increasing exposure of women to direct combat events.     

Biomechanical Study of Tandem Stance in Healthy Young Adults: Effects of Weight-Bearing and Limb Dominance

Postural strategies of healthy young adults to control tandem stance were investigated through the calculation of the relative contribution of the two loading-unloading (LU) and pressure-distribution (PD) mechanisms and the two legs for controlling the resultant center-of-pressure (CP_Res) displacements. Weight-bearing asymmetry and limb dominance were also studied. For antero-posterior and medio-lateral CP_Res displacements, LU and PD mechanisms mainly contribute, respectively. A significant LU contribution is nonetheless observed for medio-lateral control, due to a lateral gap between the CP positions under each foot despite a strict sagittal alignment for the two feet. Moreover, for medio-lateral control, the respective involvement of the two legs is related to the level of weight-bearing asymmetry, whereas the front leg mainly controls the antero-posterior sway. By specifying potential effects of body-weight asymmetry and limb dominance, to a better testing of patients with deficiencies in lateral sway control.     

Factors Predicting Likelihood of Eating Irradiated Meat

Perception of risk associated with meat irradiation was investigated in a sample of 478 respondents. Fears associated with irradiation, the relative severity and risk of bacterial infection versus potential risks due to the irradiation, and perceptions of the safety of the meat irradiation process combined to strongly predict participants' reports of their likelihood of eating irradiated meat in the present investigation. Overall, respondents were skeptical with regard to eating irradiated meat if it became locally available. Respondents' acceptance of meat irradiation was clearly driven by concerns about the risks of irradiation, but not the risks of bacterial contamination, confirming findings in the literature on differences in perception of “natural” and “technological” risks.     

‘The bereaved therapist speaks’. An interpretative phenomenological analysis of humanistic therapists' experiences of a significant personal bereavement and its impact upon their therapeutic practice: An exploratory study

Aim: The aim of the research was to explore the under‐researched area of therapists' personal bereavement and its impact upon their therapeutic practice. Method: Data were collected via semi‐structured interviews with four humanistic therapists and were analysed using Interpretative Phenomenological Analysis (IPA). Findings: Four master and eight subordinate themes emerged from the rich data collected that exemplified both convergence with and divergence from the small body of extant literature on therapist bereavement and current thinking in thanatology. The findings suggest that bereavement is a unique experience that can affect the individual's personal and social identity and worldview. It can also be a transformative experience resulting in personal growth and a renewed sense of self and agency. In terms of professional practice, the findings suggest that the lived experience of the grieving process, mediated by supportive supervision, enabled participants to experience deeper levels of empathy and connectedness within their therapeutic relationships. Conclusion and implications: Bereavement is an experience that can profoundly impact upon therapists' personal identity and assumptive world. Such an experience can have an equally profound impact upon their therapeutic practice. There are therefore implications for students, trainers, therapists and supervisors particularly in terms of self‐care and the use of the ‘self’ in therapy. Further research needs to be undertaken in order to explore in greater depth the intersection between personal bereavement and therapists' evolving personal and professional identity development.
