Imposters,Tricksters, and Trustworthiness as an Epistemic Virtue

This paper argues that trustworthiness is an epistemic virtue that promotes objectivity. I show that untrustworthy imposture can be an arrogant act of privilege that silences marginalized voices. But, as epistemologists of ignorance have shown, sometimes trickery and the betrayal of epistemic norms are important resistance strategies. This raises the question: when is betrayal of trust epistemically virtuous? After establishing that trust is central to objectivity, I argue for the following answer: a betrayal is epistemically vicious when it strengthens or promotes oppressive, exclusive networks of trust, and a betrayal is epistemically virtuous when it expands trust networks to involve the oppressed. These criteria correctly account for both the epistemic vice of a recent case of Internet imposture and the epistemic virtue of resistant tricksters.     

Predicting post‐traumatic growth and post‐traumatic stress in firefighters

Emergency service workers (e.g., firefighters, police, and paramedics) are exposed to elevated levels of potentially traumatising events through the course of their work. Such exposure can have lasting negative consequences (e.g., post‐traumatic stress disorder (PTSD)) and/or positive outcomes (e.g., post‐traumatic growth (PTG)). Research had implicated trauma, occupational and personal variables that account for variance in post‐trauma outcomes yet at this stage no research has investigated these factors and their relative influence on both PTSD and PTG in a single study. Based in Calhoun and Tedeschi's model of PTG and previous research, in this study regression models of PTG and PTSD symptoms among 218 firefighters were tested. Results indicated organisational factors predicted symptoms of PTSD, while there was partial support for the hypothesis that coping and social support would be predictors of PTG. Experiencing multiple sources of trauma, higher levels of organisational and operational stress, and utilising cognitive reappraisal coping were all significant predictors of PTSD symptoms. Increases in PTG were predicted by experiencing trauma from multiple sources and the use of self‐care coping. Results highlight the importance of organisational factors in the development of PTSD symptoms, and of individual factors for promoting PTG.     

Sample size determinations for Welch's test in one‐way heteroscedastic ANOVA

For one‐way fixed effects ANOVA, it is well known that the conventional F test of the equality of means is not robust to unequal variances, and numerous methods have been proposed for dealing with heteroscedasticity. On the basis of extensive empirical evidence of Type I error control and power performance, Welch's procedure is frequently recommended as the major alternative to the ANOVA F test under variance heterogeneity. To enhance its practical usefulness, this paper considers an important aspect of Welch's method in determining the sample size necessary to achieve a given power. Simulation studies are conducted to compare two approximate power functions of Welch's test for their accuracy in sample size calculations over a wide variety of model configurations with heteroscedastic structures. The numerical investigations show that Levy's (1978a) approach is clearly more accurate than the formula of Luh and Guo (2011) for the range of model specifications considered here. Accordingly, computer programs are provided to implement the technique recommended by Levy for power calculation and sample size determination within the context of the one‐way heteroscedastic ANOVA model.     

Exploring the link between self-compassion and body image in university women

The purpose of the present research was to examine the relationships between self-compassion and women's body image. In Study 1, female undergraduates (N=142) completed three measures of body image and measures of self-esteem and self-compassion. Results showed that high self-compassion predicted fewer body concerns independently of self-esteem. Moreover, when both self-compassion and self-esteem were included as predictors, self-compassion accounted for unique variance in body preoccupation and weight concerns whereas self-esteem did not. In Study 2, this finding was partially replicated with one component (self-judgment) of self-compassion uniquely predicting body preoccupation in undergraduate women (N=187). High scores on self-compassion also predicted less eating guilt independent of self-esteem. Additionally, self-compassion was shown to partially mediate the relationship between body preoccupation and depressive symptoms. The findings highlight the possibility that a consideration of self-compassion for body image may contribute to identifying who is most at risk for body/shape concerns.     

The Effects of Applicant Résumé Contents on Recruiters' Hiring Recommendations: The Mediating Roles of Recruiter Fit Perceptions

The résumé is the most commonly used selection tool for organisations. Past studies have demonstrated that recruiter hiring recommendations can be predicted based on the content of applicant résumés. However, the mechanisms underlying the links between résumé contents and hiring recommendations remain unclear. The present study extends previous research by examining the mediating roles of recruiters' multi‐faceted fit perceptions in a field setting. Data were collected from 216 organisational recruiters who participated in campus recruitment at seven universities in Taiwan. The results showed that applicant work experience and educational background increased recruiter hiring recommendations through recruiter perceived person–job (P–J) fit. In addition, applicant work experience predicted recruiter perceived person–organisation (P–O) fit, which in turn enhanced recruiter hiring recommendations.     

Are Dishonest Extraverts More Harmful than Dishonest Introverts? The Interaction Effects of Honesty‐Humility and Extraversion in Predicting Workplace Deviance

Honesty‐Humility, one of the six major personality dimensions included in the HEXACO model of personality structure, has previously been found to show negative correlations with workplace deviance. In this study, we hypothesised that Extraversion would moderate the relationship between Honesty‐Humility and workplace deviance. In particular, we posited that the relation between Honesty‐Humility and workplace deviance would be stronger among employees who are high on Extraversion than among those low on Extraversion. The hypothesis was tested using three different samples across Australia, Canada, and the Netherlands. It was found in two of the three samples that high levels of Extraversion did indeed amplify the relationship between (low) Honesty‐Humility and workplace deviance. Results suggest a potentially important role for multiplicative effects of personality variables on workplace criteria.     

Therapeutic alliance and progress in couple therapy: multiple perspectives

Therapeutic alliance research in couple therapy using multiple perspectives and longitudinal data has been sparse. This study used structural equation modelling to explore relationships between changes in alliance and in progress from clients' and therapists' perspective in a fairly large sample of couples (N=195) during the initial stage of therapy at an on‐campus training clinic. Self‐rated alliance was measured after sessions 2 through 4 with the Working Alliance Inventory. There was very little change in alliance over the early sessions of therapy, and changes in alliance did not always account for changes in relationship satisfaction. Husbands' perceptions of satisfaction and alliance seem to play an important role in the dynamics of the therapeutic process. Findings suggest a reciprocal relationship between perceptions of alliance and progress in therapy when combining perceptions of therapists and couple clients. Clinical implications and future research are discussed.     

We're Closer than I Thought: Social Network Heterogeneity,Morality, and Political Persuasion

Literature in the area of social networks indicates that increases in perceived social network attitudinal heterogeneity generate increased openness to attitude change. Recent evidence in the area of morality, however, shows that morally based attitudes are particularly resistant to persuasion and can result in the rejection of disagreeing others. Positing that considering morality would reduce network influence, an experiment varied moral cues presented along with a non‐network persuasive message while holding the actual content constant. Results demonstrate that morality and network composition interact to predict persuasion, such that when people are not cued to consider morality increased network heterogeneity predicts increased persuasion, but when identical messages are presented in a way that invokes morality the impact of network heterogeneity disappears or even reverses marginally. This interactive effect was replicated in two very different political issues: gay adoption and nationalized healthcare. Implications for persuasion by morally motivated sources independent of the effects of specific moral arguments are discussed.
