Healing and Hope in the Midst of Devastation: reflections on Katrina in the Aftermath of September 11

This article reflects on Hurricane Katrina within the background and context of 9/11. Included are other tragedies experienced in the School of Medicine when, combined with 9/11, laid the foundation for our continued working through Katrina.     

Construct validation of the Dutch version of the impact of event scale

The Impact of Event Scale (ES; M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) is a worldwide-used self-report measure to assess the frequency of intrusive and avoidant phenomena after a variety of traumatic experiences. The purpose of this article is to assess the psychometric value of the Dutch version of the IES (D. Brom & R. J. Kleber, 1985) in several samples of individuals who had experienced various traumatic stressors. The reliability and structure of the IES were evaluated in 3 different samples (total N = 1.588). The reliability of the Dutch version of the IES was adequate across the various stressors. The construct validity was assessed by using confirmatory factor analyses. Outcomes revealed a robust structure over the various samples, generally supporting the composition of the original IES.     

Distraction,attentional conflict,and drivelike behavior

Two studies provide evidence supporting a distraction-conflict view of social facilitation effects. Study 1 demonstrated that presence of an audience produced drivelike effects on the latency and vigor of a motor response. This effect, however, only occurred when attending to the audience caused attentional conflict. Study 2 demonstrated that in a two-task setting, attentional conflict, resulting from having to choose which task to work on, led to poorer performance on a complex copying task (p < .01, one tailed) and a larger percentage of dominant responses on J. L. Cohen and J. H. Davis' (Journal of Personality and Social Psychology, 1973, 27, 74–85) hidden word task (p < .04, one tailed), relative to a yoked control. Study 2 is consistent with earlier reports that choice heightens drivelike effects, while Study 1 indicates that attentional conflict contributes to social facilitation phenomena.     

Type A Behavior,Experience, and Salesperson Performance

The findings of this study indicate that Type A behavior pattern, working indirectly through role clarity and effort, has a significant impact on performance. Experience was also found to relate to performance both directly and through role clarity. In the particular type of outcome-based sales setting where individual autonomy and entrepreneurship are encouraged, personal characteristics have significance for performance. Recruiting appropriate salespeople and retaining effective experienced individuals is critically important in environments that emphasize individualism and internal competition.     

Integrating leadership: The leadership circumplex

The present study aims to integrate leadership conceptualizations into one overarching model, using a “leadership circumplex”. Two studies describe the construction and examine the psychometric characteristics of an operationalization of the leadership circumplex, the Circumplex Leadership Scan (CLS). Results showed that the CLS complies with the criteria of a true circumplex. Furthermore, scales, representing leadership styles, showed reasonable to high reliability. A third study confirmed the stability of the CLS structure and additionally explored the circumplex structure of subordinates’ ratings of their leaders, which were found to have the same underlying circumplex structure. A fourth study was conducted to assess the convergent validity with other leadership styles from the existing leadership literature, the predictive validity of the styles, as well as the test–retest reliability. A fifth study confirmed the predictive validity results observed in Study 4 using different-source ratings of leadership outcomes. Finally, a sixth study explored the possibility of creating a short version of the CLS.     

A review of research on the prevalence,antecedents, consequences and prevention of workplace aggression in clinical medical practice

A broad-ranging review of the published research literature was undertaken on workplace aggression in clinical medical practice. Prevalence studies have found that 15–75% of survey respondents reported verbal aggression and 2–29% reported physical aggression in medical practice settings in the previous 6–24 months. In comparison, there was limited published research on the antecedents and consequences of clinician exposure to workplace aggression, and a dearth of published research on the prevention and minimization of workplace aggression in medical practice settings. Future research efforts need to investigate workplace aggression from all sources and across all medical clinician sub-populations in the diverse settings in which they work. Specific attention needs to be given to identifying key risk and protective factors for workplace aggression exposure, including in relation to clinician profiles, the settings and conditions of medical work, and the presence of key aggression prevention and minimization efforts, both individually and in combination. The impact of workplace aggression on clinician health, well-being, performance and work participation remains under-researched. Overall, a more extensive and robust evidence base is required to enable informed decision-making on reducing the likelihood and consequences of workplace aggression in clinical medical practice.     

Temporal considerations in the study of family firms: Reflections on “the study of organizational behaviour in family business”

We complement the work of Gagné et al. by discussing how an extended time dimension shapes organizational behaviour in family firms. Using insights from family dynamics, identity theory, and social identity theory, we show how early formative experiences in the family can influence commitment, conflict, and motivation in family firms. Then we examine how a family's intention to pass on the firm to later generations can impact leadership, human-resources practices, and corporate cultures.     

A puzzle about natural laws and the existence of God

The existence of natural laws, whether deterministic or indeterministic, and whether exceptionless or ceteris paribus, seems puzzling because it implies that mindless bits of matter behave in a consistent and co-ordinated way. I explain this puzzle by showing that a number of attempted solutions fail. The puzzle could be resolved if it were assumed that natural laws are a manifestation of God’s activity. This argument from natural law to God’s existence differs from its traditional counterparts in that, whereas the latter seek to explain the fact of natural laws, the former seeks to explain their possibility. The customary objections to the traditional arguments cannot be successfully adapted to counter this new argument, with one exception which has only limited effect. I rebut four claims that the theistic solution to the puzzle about natural laws is paradoxical, though I concede that one of these claims has merit. I consider four objections to the new argument but find three of them more or less unsatisfactory. The fourth, if successful, would undermine our claims to know the truth about the world.     

The Impact Message Inventory–Circumplex (IMI–C): A Replication Study of Its Circumplex Structure in a Dutch Sample

The 56-items Impact Message Inventory–Circumplex (IMI–C) has been developed to describe the interpersonal styles of target persons in terms of the 2-dimensional interpersonal circle, divided in 8 subscales (octants). The IMI–C is based on the assumption that a target person's interpersonal styles can validly be measured by assessing the internal (cognitive and emotional) reactions of the IMI–C respondent (e.g., therapists), interacting with the target person (e.g., psychotherapy patients). This replication study tested the circumplexity of a computer-delivered Dutch IMI–C. The computer-delivered Dutch IMI–C approached circumplexity in a large clinical sample (N = 812) of psychotherapy and psychiatric patients, after removing 3 items from the Submissive octant scale. These 3 items clearly disturbed the IMI–C circumplex structure. It is concluded that, even with the inevitable problem of nested data, circumplexity was approached sufficiently to justify the interpretation of the IMI–C at the octant level, provided that the 3 troublesome Submissive items are removed from the calculations of octant scores. Our replication test of the Dutch IMI–C circumplexity might be an impetus for researchers in the United States to invest in the further validation of the original American version.     

Long term course of chronic posttraumatic stress disorder in traffic accident victims: a three-year prospective follow-up study

The purpose of the present study was to gather prospective longitudinal data on the long-term course and outcome of chronic posttraumatic stress disorder (PTSD). The target population for this study was 74 injured traffic accident victims who had been previously followed-up for one year after the trauma. Nineteen of the original 24 PTSD subjects (79%) and 39 of the original 50 Non-PTSD subjects (78%) were available for this study, which took place during the fourth year after the accident. Our results show that 10 (53%) of the 19 patients with PTSD at one-year still suffered from PTSD after another two-year follow-up interval, while 9 recovered from PTSD during this follow-up period. Only 2 of the 39 without PTSD at one year developed delayed onset PTSD. The best predictor of recovery from chronic PTSD was the initial level of posttraumatic reaction immediately after the accident. These results demonstrate that spontaneous recovery from PTSD can occur even among patients who are currently considered chronic. Severity of initial reaction to the trauma appears to be a major risk factor for non-remitting chronic PTSD.
