Exploring gender differences in body image,eating pathology,and sexual harassment

This study examines the relationship between body image (weight/shape concerns), eating pathology, and sexual harassment among men and women (N = 2446). Hierarchical regressions controlling for depression revealed main effects of gender such that women reported greater weight/shape concerns, eating pathology, dietary restraint, eating concerns, and binge eating compared to men. Main effects for sexual harassment indicated that as harassment increased, participants reported increased weight/shape concerns, eating pathology, dietary restraint, eating concerns, binge eating, and compensatory behaviors. There were small but significant interactions between gender and harassment for eating pathology total score (which included each of the domains listed above), weight/shape concerns, dietary restraint, and eating concerns such that the relationship between increased harassment and increased pathology was stronger for women compared to men. The largest interaction was found for compensatory behaviors, such that while women and men's scores both increased as harassment increased, the relationship was stronger for men.     

Development in reading and math in children from different SES backgrounds: the moderating role of child temperament

Socioeconomic risks (SES risks) are robust risk factors influencing children's academic development. However, it is unclear whether the effects of SES on academic development operate universally in all children equally or whether they vary differentially in children with particular characteristics. The current study aimed to explore children's temperament as protective or risk factors that potentially moderate the associations between SES risks and academic development. Specifically, latent growth modeling (LGM) was used in two longitudinal datasets with a total of 2236 children to examine how family SES risks and children's temperament interactively predicted the development of reading and math from middle childhood to early adolescence. Results showed that low negative affect, high effortful control, and low surgency mitigated the negative associations between SES risks and both reading and math development in this developmental period. These findings underline the heterogeneous nature of the negative associations between SES risks and academic development and highlight the importance of the interplay between biological and social factors on individual differences in development.     

Low‐price guarantees as advertisement strategy and compensation policy: The more,the better?

Companies sometimes employ a “lowest price or more than the difference back” policy (i.e., a price‐beating guarantee). We investigated whether such a policy is more effective to attract and retain customers than when the exact price difference is promised (i.e., a price‐matching guarantee). The first study revealed that about 60% of the marketers and shop owners in our sample thought that beating price differences is a more effective strategy than matching price differences. However, the four subsequent studies challenged this assumption. Specifically, the advertisement as well as the provision of price‐beating refunds did not have an incremental positive effect on customers' general attitudes in terms of trust, brand perception, loyalty, and shopping intentions beyond the level that was already reached by price‐matching refunds. Moreover, our mediation analyses revealed that the null effect of price‐matching versus price‐beating was mediated by fairness perceptions. From a theoretical perspective, these results are in line with a fairness account, which holds that people do not only evaluate the economic value of an outcome, but also take equality considerations into account. Because price‐beating is literally more expensive than price‐matching, from a practical point of view, companies should be informed that the employment of a price‐beating guarantee is a cost‐ineffective advertisement strategy and compensation policy.     

The Unravelling of Identities and Belonging: Criminal Gang Involvement of Youth from Immigrant Families

Grounded in the experiences of 30 gang-involved respondents in Calgary, this Canadian study examined criminal gang involvement of youth from immigrant families. Our analysis showed that gang-involved youth had experienced multiple, severe and prolonged personal and interpersonal challenges in all facets of their lives and that gradual disintegration of their relationships with family, school and community had resulted in the unravelling of self-concept, ethnic identity, sense of belonging and sense of citizenship and progressively propelled them towards membership in high-risk social cliques and criminal gangs. Our findings brought attention to the need for coordinated, comprehensive support for youth from immigrant families through family-based, school-based and community-based programs.     

Do Narrative Engagement and Recipients’ Thoughts Explain the Impact of an Entertainment-Education Narrative on Discouraging Binge Drinking?

Previous research suggests that narrative engagement (NE) in entertainment-education (E-E) narratives reduces counterarguing, thereby leading to E-E impact on behavior. It is, however, unclear how different NE processes (narrative understanding, attentional focus, emotional engagement, narrative presence) relate to different thought types (negative or positive; about the narrative form or about the target behavior) and to E-E impact. This study explores these relations in the context of alcohol binge drinking (BD). Participants (N = 172) watched an E-E narrative showing negative BD consequences, thereby aiming to discourage BD. The main findings were that the E-E narrative had a positive impact on discouraging BD on almost all assessed BD determinants such as beliefs and attitude. It was shown that attentional focus, emotional engagement, and narrative presence were associated with BD-discouraging impact, albeit on different BD-related determinants. No evidence was found that negative thoughts about BD mediated these associations. From this, we conclude that attentional focus, emotional engagement, and narrative presence were important for E-E impact but that negative thoughts about BD did not play a role therein. The study’s empirical and practical implications are discussed.     

Coping with Sexual Identity Stigma in the U.S. Military: An Examination of Identity Management Practices Prior to and After the Repeal of “Don’t Ask,Don’t Tell”

This study assesses the identity management strategies employed by gays, lesbians, and bisexuals in the U.S. military prior to and after the repeal of “Don’t Ask, Don’t Tell.” In-depth interviews were conducted with gay, lesbian, and bisexual service members and veterans. Data were analyzed using constant comparative analysis. Findings revealed that these service members made thoughtful and deliberate decisions about whether or not, and to whom, they would reveal their sexual identities. Identity concealment was practiced most often, even after the repeal, which was found to incite feelings of self-reproach, isolation, and stress. However, several new identity management strategies emerged after the repeal of “Don’t Ask, Don’t Tell” (i.e., strategies of openness) that stimulated positive self-feelings. By engaging in some level of openness, participants in this study were able to overcome some of the adverse effects of their minority stress.     

3-minute smartphone-based and tablet-based psychomotor vigilance tests for the assessment of reduced alertness due to sleep deprivation

The psychomotor vigilance test (PVT) is widely used to measure reduced alertness due to sleep loss. Here, two newly developed, 3-min versions of the psychomotor vigilance test, one smartphone-based and the other tablet-based, were validated against a conventional 10-min laptop-based PVT. Sixteen healthy participants (ages 22–40; seven males, nine females) completed a laboratory study, which included a practice and a baseline day, a 38-h total sleep deprivation (TSD) period, and a recovery day, during which they performed the three different versions of the PVT every 3 h. For each version of the PVT, the number of lapses, mean response time (RT), and number of false starts showed statistically significant changes across the sleep deprivation and recovery days. The number of lapses on the laptop was significantly correlated with the numbers of lapses on the smartphone and tablet. The mean RTs were generally faster on the smartphone and tablet than on the laptop. All three versions of the PVT exhibited a time-on-task effect in RTs, modulated by time awake and time of day. False starts were relatively rare on all three PVTs. For the number of lapses, the effect sizes across 38 h of TSD were large for the laptop PVT and medium for the smartphone and tablet PVTs. These results indicate that the 3-min smartphone and tablet PVTs are valid instruments for measuring reduced alertness due to sleep deprivation and restored alertness following recovery sleep. The results also indicate that the loss of sensitivity on the 3-min PVTs may be mitigated by modifying the threshold defining lapses.     

Effects of repetition on age differences in associative recognition

The study reported here examined the effect of repetition on age differences in associative recognition using a paradigm designed to encourage recollection at test. Young and older adults studied lists of unrelated word pairs presented one, two, four, or eight times. Test lists contained old (intact) pairs, pairs consisting of old words that had been studied with other partners (rearranged lures), and pairs consisting of two unstudied words (new lures). Participants gave old/new responses and then indicated whether their responses were based on details that they could recollect or on familiarity. Older adults exhibited an ironic effect of repetition—an increase in false alarms on rearranged lures with more study opportunities—whereas young adults did not. Older adults also claimed to recall details of the study episode for rearranged lures whose constituent words were presented more frequently, but this was not true for young adults. Although both young and older adults said that they based correct rejections of rearranged lures on memory for details of the study episode, this effect was stronger for young adults. The observed age differences are consistent with older adults having reduced use of recollection in associative recognition tasks.     

The Five Senses of Haiti

The Five Senses of Haiti discusses a series of medical mission trips by physicians and medical students to the Central Plateau of Haiti delivering care in the outpatient setting. Practitioners describe their experiences through the use of their five senses to draw contrast between modern health care and medical practice in the developing world. Physicians in a resource poor setting are left without the usual diagnostic armamentarium and the safeguards and distractions of the modern hospital setting. This deficit creates an opportunity to devote time and focus to individual patients. Practicing medicine in this context clinicians use a heightened sense of awareness and increase their reliance on physical exam findings. Global medicine creates an opportunity for medical students to learn and physicians out of training to practice overlooked physical exam skills in the modern era. Physical exam findings and patient care yield diagnoses and fosters the bonds of the doctor-patient relationship.
