Living donation and cosmetic surgery: a double standard in medical ethics?

The commitment of transplant physicians to protect the physical and psychological health of potential donors is fundamental to the process of living donor organ transplantation. It is appropriate that strict regulations to govern an individual's decision to donate have been developed. Some may argue that adherence to such regulations creates a doctor-patient relationship that is rooted in paternalism, which is in drastic contrast with a doctor-patient relationship that is rooted in patients' autonomy, characteristic of most other operative interventions. In this article we analyze the similarities between cosmetic plastic surgery and living donor surgery as examples of surgeries governed by different ethical principles. It is interesting that, while the prevailing ethical approach in living donor surgery is based on paternalism, the ethical principle guiding cosmetic surgery is respect for patients' autonomy. The purpose of this article is not to criticize either practice, but to suggest that, given the similarities between the two procedures, both operative interventions should be guided by the same ethical principle: a respect for patients' autonomy. We further suggest that if living organ donation valued donors' autonomy as much as cosmetic plastic surgery does, we might witness a wider acceptance of and increase in living organ donation.     

Veridical and false memory for scenic material in posttraumatic stress disorder

The question whether memory aberrations in posttraumatic stress disorder (PTSD) also manifest as an increased production of false memories is important for both theoretical and practical reasons, but is yet unsolved. Therefore, for the present study we investigated veridical and false recognition in PTSD with a new scenic variant of the Deese-Roediger-McDermott (DRM) paradigm, which was administered to traumatized individuals with PTSD (n=32), traumatized individuals without PTSD (n=30), and non-traumatized controls (n=30). The PTSD group neither produced higher rates of false memories nor expressed more confidence in errors, but did show inferior memory sensitivity. Whereas depressive symptoms did not correlate with veridical nor false recognition, state dissociation was positively associated with false memories.     

“He Cursed, and I Got Angry:” Beliefs About Anger Among Adolescent Male Offenders in India

Cultural influences in the experience and expression of emotions have been widely recognized, although systematic studies of emotion-related beliefs in culturally diverse families have been scarce. The purpose of the present exploratory study was to examine beliefs about anger among a group of adolescent male offenders in India temporarily residing in a pre-sentencing institution. In particular, adolescent offenders (n = 14) were individually interviewed about their beliefs concerning causes and concomitants of, and behavioral responses to, one’s own and others’ anger, as well as family patterns of anger expression that are crucial in understanding socialization processes. Although some of the themes reflected in their narratives parallel the beliefs of educated, middle-class, non-offender youth in India (e.g., social inappropriateness of anger), as well as those of offenders in other parts of the world (e.g., aggressive behavior as a common response to anger), beliefs about various aspects of anger specific to this subculture of offender youth also emerged. In particular, perceived violations of family honor were cited as the most common elicitors of anger, and although anger was considered ‘bad’ it was expressed through aggression. The findings of this study highlight the need to develop a culturally informed theory of emotions, and relatedly, to develop culturally sensitive interventions for anger management that can be incorporated as a part of rehabilitation efforts for offender youth in India.     

Gender Differences in the Social Functioning of Adolescents with Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) has been associated with social difficulties. Boys with IBD may have increased risk for social problems due to delayed growth and puberty, but gender differences in social functioning have not been investigated. This study examined gender differences in multiple areas of social functioning for adolescents with IBD compared to healthy adolescents. Participants were 92 adolescents 11-17?years (50 with IBD, 42 healthy) and parents who completed questionnaires assessing social functioning. IBD was associated with poorer social functioning in the areas of social competence and social problems. Boys with IBD had worse social competence, with no gender differences for social problems. Gender predicted the use of social contact as a coping strategy, but no significant group differences were found for other areas of social functioning. Adolescents with IBD experience significant social difficulties in some areas, and boys are at risk for poor social competence. However, previously reported social difficulties may not extend to all areas of social functioning.     

Associations Between Positive Development in Late Adolescence and Social, Health, and Behavioral Outcomes in Young Adulthood

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood.     

TRAINING STAFF TO INCREASE MANDING IN STUDENTS WITH AUTISM: TWO PRELIMINARY CASE STUDIES

Two case studies evaluated two versions of behavioral skills training on peer‐to‐peer manding. Case Study 1 evaluated the full package of instructions, modeling, rehearsal, and feedback, and Case Study 2 used modeling and feedback only. Both case studies employed AB designs. In both case studies, staff increased correct teaching responses, and students increased the number of independent peer‐to peer mands. These pilot data suggest that staff can readily acquire teaching skills to increase peer‐to‐peer manding and that modeling and feedback may be sufficient to train staff to do so.

Eye tracking, strategies, and sex differences in virtual navigation

Reports of sex differences in wayfinding have typically used paradigms sensitive to the female advantage (navigation by landmarks) or sensitive to the male advantage (navigation by cardinal directions, Euclidian coordinates, environmental geometry, and absolute distances). The current virtual navigation paradigm allowed both men and women an equal advantage. We studied sex differences by systematically varying the number of landmarks. Eye tracking was used to quantify sex differences in landmark utilisation as participants solved an eight-arm radial maze task within different virtual environments. To solve the task, participants were required to remember the locations of target objects within environments containing 0, 2, 4, 6, or 8 landmarks. We found that, as the number of landmarks available in the environment increases, the proportion of time men and women spend looking at landmarks and the number of landmarks they use to find their way increases. Eye tracking confirmed that women rely more on landmarks to navigate, although landmark fixations were also associated with an increase in task completion time. Sex differences in navigational behaviour occurred only in environments devoid of landmarks and disappeared in environments containing multiple landmarks. Moreover, women showed sustained landmark-oriented gaze, while men's decreased over time. Finally, we found that men and women use spatial and response strategies to the same extent. Together, these results shed new light on the discrepancy in landmark utilisation between men and women and help explain the differences in navigational behaviour previously reported.     

Selecting a linear mixed model for longitudinal data: repeated measures analysis of variance, covariance pattern model, and growth curve approaches

With increasing popularity, growth curve modeling is more and more often considered as the 1st choice for analyzing longitudinal data. Although the growth curve approach is often a good choice, other modeling strategies may more directly answer questions of interest. It is common to see researchers fit growth curve models without considering alterative modeling strategies. In this article we compare 3 approaches for analyzing longitudinal data: repeated measures analysis of variance, covariance pattern models, and growth curve models. As all are members of the general linear mixed model family, they represent somewhat different assumptions about the way individuals change. These assumptions result in different patterns of covariation among the residuals around the fixed effects. In this article, we first indicate the kinds of data that are appropriately modeled by each and use real data examples to demonstrate possible problems associated with the blanket selection of the growth curve model. We then present a simulation that indicates the utility of Akaike information criterion and Bayesian information criterion in the selection of a proper residual covariance structure. The results cast doubt on the popular practice of automatically using growth curve modeling for longitudinal data without comparing the fit of different models. Finally, we provide some practical advice for assessing mean changes in the presence of correlated data.
