A Qualitative Analysis of Power Differentials in Ethical Situations in Academia

Power and organizational hierarchies are ubiquitous to social institutions that form the foundation of modern society. Power differentials may act to constrain or enhance people’s ability to make good ethical decisions. However, little scholarly work has examined perceptions of this important topic. The present effort seeks to address this issue by interviewing academics about hypothetical ethical problems that involve power differences among those involved. Academics discussed what they would do in these scenarios, often drawing on their own experiences. Using a think-aloud protocol, participants were prompted to discuss their reasoning and thinking behind their ethical decisions. These interview data were content analyzed using a semantic analysis program that identified a number of distinct ways that academics think about power differences and abuses in ethical situations. Implications of these findings are discussed.     

Ensemble coding of faces occurs in children and develops dissociably from coding of individual faces

Ensemble coding allows adults to access useful information about average properties of groups, sometimes even in the absence of detailed representations of individual group members. This form of coding may emerge early in development with initial reports of ensemble coding for simple properties (size, numerosity) in young children and even infants. Here we demonstrate that ensemble coding of faces, which provides information about average properties of social groups, is already present in 6–8‐year‐old children. This access to average information increases with age from 6 to 18 years and its development is dissociable from age‐related improvements in the coding of individual face identities. This dissociation provides the first direct evidence that distinct processes underlie ensemble and individual coding of face identity, evidence that has been lacking from adult studies. More generally, our results add to the emerging evidence for impressively mature sensitivity to statistical properties of the visual environment in children. They indicate that children have access to gist information about social groups that may facilitate adaptive social behaviour.     

Protecting Women from the Negative Effects of Body Dissatisfaction: The Role of Differentiation of Self

ABSTRACT

Body dissatisfaction is a prevalent and concerning issue among college age women. Due to its strong association with eating pathology, identification of moderating variables is a crucial line of inquiry. The present study investigated the ability for an intrapersonal differentiation-of-self variable (“I” position) to attenuate the impact of body dissatisfaction on anorexia and bulimia symptoms among college women participants. Study findings indicated that an “I” position moderated the body dissatisfaction-bulimia relationship and the body dissatisfaction-anorexia relationship. These findings signified the protective influence of a high “I” position for women with high levels of body dissatisfaction. Research and therapeutic implications are discussed.     

BETWEEN KNOWING AND BEING: REFLECTIONS ON BEING TAUGHT SCIENCE AND RELIGION BY PROFESSOR CHRISTOPHER SOUTHGATE

It is a joy to be asked to contribute to this commemorative edition of Zygon, in honor of my friend Christopher Southgate. But a narrowly academic article seems not to fit the brief of writing a reflection on Southgate's teaching of science and religion, as one who has witnessed it, gladly, as both student and colleague. What follows, then, is deliberately reflective in tone, with little in the way of academic references apart from occasional links to Southgate's own work—though, I hope, enough of a strand of argument to justify inclusion in these pages. My argument is simply put: Southgate teaches by not teaching, but by drawing out knowledge from students and thereby empowering their growth. He is an exemplar, a kind man committed to the unfolding of understanding, interested too in forming dispositions in his students that will lead to their flourishing as thinkers and as people.     

Like Father,like Child: Early Life Family Adversity and Children’s Bullying Behaviors in Elementary School

Family adversity has been associated with children’s bullying behaviors. The evidence is, however, dominated by mothers’ perceptions of the family environment and a focus on mothers’ behaviors. This prospective population-based study examined whether children’s bullying behaviors were associated with mother- and father-reported family adversity, assessed before and after child birth. Peer-nominations were used to assess bullying behaviors of 1298 children in elementary school (mean age 7.5 years). The following paternal risk factors were prospectively associated with children’s bullying behaviors: (1) father-reported prenatal family distress, (2) fathers’ hostility at preschool age, and (3) fathers’ harsh disciplinary practices at preschool age, but effect sizes were relatively small. The effect of maternal risk factors was less consistent, only mother-reported family distress in childhood was associated with children’s bullying behaviors. The associations were independent of background family risk factors (i.e., life stress, contextual factors, and other background factors such as parental education and risk taking record) and early childhood externalizing problems. Moreover, our results indicated that father-reported family adversity predicted children’s bullying behaviors over and above the background family risk factors, early childhood externalizing problems and mother-reported family adversity. We also demonstrated that the association of fathers’ prenatal hostility and family distress with subsequent bullying behavior of their child at school was partly mediated by fathers’ harsh disciplinary practices at preschool age. Our findings highlight the importance of fathers’ behaviors in the development of children’s bullying behaviors.
