Social support, coping, life events, and posttraumatic stress symptoms among former peacekeepers: a prospective study

This study examined both cross-sectionally and longitudinally the relationship between social support, coping strategies, additional stressful life events, and symptoms of posttraumatic stress disorder (PTSD) among Dutch former peacekeeping soldiers. Two groups of peacekeepers were investigated: 311 peacekeepers who participated in the peacekeeping operation in Lebanon between 1979 and 1985, and 499 peacekeepers who were deployed after 1990. These peacekeepers completed a questionnaire in 1996 and again in 1998. The results show that more negative social contacts and fewer positive social contacts were associated with more PTSD symptom severity. More use of the coping strategies ‘wishful thinking’ and ‘accepting responsibility’ was related to more PTSD symptoms. Conversely, more planful problem solving and seeking social support was related to less PTSD symptom severity. In addition, a bilateral relationship was found between additional stressful life events and PTSD symptom severity. The results indicate that social support and coping strategies may be valuable aspects of prevention and intervention programs.     

Engendering Culture: The Relationship of Gender Identity and Pressure for Gender Conformity with Adolescents’ Interests in the Arts and Literature

Research indicates that women are more interested in highbrow culture (i.e., the arts—art, music, and theatre—and literature) than men are. Current explanations for women’s higher involvement in highbrow cultural activities primarily focus on adults; overemphasize class-, work- and cultural capital-related explanations; and do not uncover the identity-related and interactional mechanisms behind the gendering of taste during socialization. In the present paper we use gender identity theory and a “doing gender” perspective to understand cultural taste differences between male and female adolescents. Using multilevel analyses on a random sample of 5227 Flemish 7th graders (M _age = 12.18) who completed a survey in their classrooms, we find that higher gender typicality (i.e., identification as a typical male or female) and higher pressure to conform to gender stereotypes are associated with slightly higher interests in arts-, theatre-, and literature-related activities for young women, but with much lower highbrow interests for young men. This difference indicates that identity-related processes and interactional conformity pressures are important mechanisms reinforcing the gendering of cultural tastes. Implications for research on gender, class, and cultural capital, as well as potential ways to make schools safe environments for the expression of gender non-stereotypical cultural tastes, are discussed.     

Does worry affect adjustment to bereavement? A longitudinal investigation

Background and objectives: Repetitive thought is a trans-diagnostic risk-factor for development of psychopathology. Research on repetitive thought in bereaved individuals has focused primarily on clarifying the role of rumination, repetitive thinking about past negative events and/or negative emotions. While detrimental effects of rumination have been demonstrated following bereavement, surprisingly few studies have aimed to clarify the role of worry, repetitive thinking about potential future negative events, in adjustment to loss. This study sought to fill this gap in knowledge. Methods/Design: One hundred eighty-three bereaved individuals (85.3% women) filled out questionnaires on sociodemographic and loss-related characteristics, worry, and symptom measures of depression, anxiety, and prolonged grief. After six months, 155 participants completed worry and symptom measures again. Using multiple regression analyses, concurrent and longitudinal associations between loss-related variables, worry, and symptoms of psychopathology were examined. Results: Main results were that worry was strongly positively associated with symptoms of anxiety, depression and prolonged grief concurrently and also predicted higher levels of anxiety, depression and prolonged grief longitudinally. Conclusions: Findings suggest that worry influences adjustment to bereavement negatively and may be a potential target in grief therapy, especially when aiming to reduce anxiety.     

Broadening Ethics Teaching in Engineering: Beyond the Individualistic Approach

There is a widespread approach to the teaching of ethics to engineering students in which the exclusive focus is on engineers as individual agents and the broader context in which they do their work is ignored. Although this approach has frequently been criticised in the literature, it persists on a wide scale, as can be inferred from accounts in the educational literature and from the contents of widely used textbooks in engineering ethics. In this contribution we intend to: (1) Restate why the individualistic approach to the teaching of ethics to engineering students is inadequate in view of preparing them for ethical, professional and social responsibility; (2) Examine the existing literature regarding the possible contribution of Science, Technology and Society (STS) scholarship in addressing the inadequacies of the individualistic approach; and (3) Assess this possible contribution of STS in order to realise desired learning outcomes regarding the preparation of students for ethical and social responsibility.     

Perception of the color red enhances the force and velocity of motor output

The present research examined whether perception of the color red influences basic motor functioning. Prior research on color and motor functioning has been guided by ill-defined theoretical statements, and has been plagued by methodological problems. Drawing on theoretical and empirical work on the threat-behavior link in human and nonhuman animals, we proposed and tested the prediction that perceiving red enhances the force and velocity of motor output. Experiment 1 demonstrated that red, relative to gray (matched to red on lightness), facilitates pinchgrip force. Experiment 2 demonstrated that red, relative to gray (matched to red on lightness) and blue (matched to red on lightness and chroma) facilitates handgrip force and the velocity of that force. These findings clearly establish a link between red and basic motor action, illustrate the importance of rigorous experimental methods when testing color effects, and highlight the need to attend to the functional, as well as aesthetic, value of color.     

When to Refrain from Using Likelihood Surface Methods for Geographic Offender Profiling: An Ex Ante Test of Assumptions

Likelihood surface methods for geographic offender profiling rely on several assumptions regarding the underlying location choice mechanism of an offender. We propose an ex ante test for checking whether a given set of crime locations is compatible with two necessary assumptions: circular symmetry and distance decay. The proposed (SDD) test compares the observed inter point distances of a given series of crimes with a theoretical distribution function governed by these assumptions, using a Monte Carlo simulation procedure for approximating that distribution function. We apply the SDD test to data on serial burglary from both the UK and the Netherlands. In most cases, the assumption of an underlying symmetric distance decay function has to be rejected.

Unintentional preparation of motor impulses after incidental perception of need-rewarding objects

Using a new method, we examined whether incidental perception of need-rewarding (positive) objects unintentionally prepares motor action. Participants who varied in their level of need for water were presented with glasses of water (and control objects) that were accompanied by go and no-go cues that required a response (key-press) or withholding a response. Importantly, if need-rewarding objects unintentionally prepare action, presentation of no-go cues should lead to motor inhibition of these prepared motor impulses. Consistent with this hypothesis, results showed that participants relatively high in need for water (and hence, who perceive water as a rewarding, positive object) were slower to react to a successive action probe after withholding a response during perception of water than during perception of the control object, suggesting motor inhibition of unintentionally prepared motor impulses. We propose that incidental perception of need-rewarding objects unintentionally potentiates preparation of motor action to these objects.     

Construct Validity of Multi‐Source Performance Ratings: An Examination of the Relationship of Self‐, Supervisor‐, and Peer‐Ratings with Cognitive and Personality Measures

Although more and more organizations prefer using multi‐source performance ratings or 360° feedback over traditional performance appraisals, researchers have been rather skeptical regarding the reliability and validity of such ratings. The present study examined the validity of self‐, supervisor‐, and peer‐ratings of 195 employees in a Dutch public organization, using scores on an In‐Basket exercise, an intelligence test, and a personality questionnaire as external criterion measures. Interrater agreement ranged from .28 to .38. Variance in the ratings was explained by both method and content factors. Support for the external construct validity was rather weak. Supervisor‐ratings were not found to be superior to self‐ and peer‐ratings in predicting the scores on the external measures.
