Characteristics of Dieting and Nondieting Adolescents in a Psychiatric Inpatient Setting

  The clinical and psychosocial characteristics of 239 dieting and nondieting adolescents (61% female; mean age=15.3) recruited from an inpatient psychiatric setting were examined. Dieting adolescents were compared to nondieting adolescents on exercise frequency, weight control behaviors, risky behaviors, psychiatric comorbidity and distress, eating disorder symptomatology, smoking, coping, and family factors. While dieters did not statistically differ from nondieters on scores of body mass index, dieting youth reported greater levels of self-reported distress, poorer coping, greater eating disorder symptomatology, and were more likely to engage in extreme weight control behaviors. In addition, dieting was associated with higher rates of major depression (58% vs 34%) and eating disorders (14% vs 1%). Among adolescent smokers, dieters endorsed smoking as a weight control behavior. Engaging in risky behaviors or familial factors did not differentiate dieters from nondieters. Given the number of negative correlates associated with dieting in adolescents, identifying dieting and weight control behaviors in clinical settings may prove to be an effective strategy in the development of prevention and intervention efforts for youth.     

International federation for information processing’s framework for computer ethics

This paper reviews codes of ethics and codes of conduct from different countries. The differences and similarities between code content and between attitudes are considered. Distinction is drawn between a code of ethics and a code of conduct. Recommendations are made for establishing a common framework for IFIP (International Federation for Information Process) Member or Affiliate Societies.     

Adjusting foraging strategies: a comparison of rural and urban common mynas (<Emphasis Type="Italic">Acridotheres tristis</Emphasis>)

Establishment in urbanized environments is associated with changes in physiology, behaviour, and problem-solving. We compared the speed of learning in urban and rural female common mynas, Acridotheres tristis, using a standard visual discrimination task followed by a reversal learning phase. We also examined how quickly each bird progressed through different stages of learning, including sampling and acquisition within both initial and reversal learning, and persistence following reversal. Based on their reliance on very different food resources, we expected urban mynas to learn and reversal learn more quickly but to sample new contingencies for proportionately longer before learning them. When quantified from first presentation to criterion achievement, urban mynas took more 20-trial blocks to learn the initial discrimination, as well as the reversed contingency, than rural mynas. More detailed analyses at the level of stage revealed that this was because urban mynas explored the novel cue-outcome contingencies for longer, and despite transitioning faster through subsequent acquisition, remained overall slower than rural females. Our findings draw attention to fine adjustments in learning strategies in response to urbanization and caution against interpreting the speed to learn a task as a reflection of cognitive ability.     

Associations of non‐symbolic and symbolic numerical magnitude processing with mathematical competence: a meta‐analysis

Many studies have investigated the association between numerical magnitude processing skills, as assessed by the numerical magnitude comparison task, and broader mathematical competence, e.g. counting, arithmetic, or algebra. Most correlations were positive but varied considerably in their strengths. It remains unclear whether and to what extent the strength of these associations differs systematically between non‐symbolic and symbolic magnitude comparison tasks and whether age, magnitude comparison measures or mathematical competence measures are additional moderators. We investigated these questions by means of a meta‐analysis. The literature search yielded 45 articles reporting 284 effect sizes found with 17,201 participants. Effect sizes were combined by means of a two‐level random‐effects regression model. The effect size was significantly higher for the symbolic (r = .302, 95% CI [.243, .361]) than for the non‐symbolic (r = .241, 95% CI [.198, .284]) magnitude comparison task and decreased very slightly with age. The correlation was higher for solution rates and Weber fractions than for alternative measures of comparison proficiency. It was higher for mathematical competencies that rely more heavily on the processing of magnitudes (i.e. mental arithmetic and early mathematical abilities) than for others. The results support the view that magnitude processing is reliably associated with mathematical competence over the lifespan in a wide range of tasks, measures and mathematical subdomains. The association is stronger for symbolic than for non‐symbolic numerical magnitude processing. So symbolic magnitude processing might be a more eligible candidate to be targeted by diagnostic screening instruments and interventions for school‐aged children and for adults.     

How do generic statements impact performance? Evidence for entity beliefs

Generic statements about the abilities of children's social groups (e.g. ‘Girls/Boys are good at this game’) negatively impact children's performance – even if the statements are favorable towards children's own social groups. We explored the mechanism by which generic language impairs children's performance. Across three studies, our findings suggest that generic statements influence children's performance by creating an entity belief (i.e. a belief that a fixed ability determines performance). Children who were exposed to a generic statement about their social group's ability performed worse than children in control conditions. This effect hurt children's performance even when the person who made the generic statement was no longer present and a new person not privy to the statement replaced them. However, when children heard a generic statement paired with an effort explanation (i.e. ‘Girls/Boys are good at this game because they try really hard when they draw’) they performed better than children who heard the generic statement with no explanation (i.e. just ‘Girls/Boys are good at this game’) and children who heard the generic statement paired with a trait explanation (i.e. ‘Girls/Boys are good at this game because they are smart and really good at drawing’). This work uncovers when and how generic statements that refer to the ability of one's social group hinder performance, informing the development of practices to improve student motivation and learning.     

Applying organizational justice theory to admission into higher education: Admission from a student perspective

Applicant perceptions of methods used in admission procedures to higher education were investigated using organizational justice theory. Applicants to a psychology study program completed a questionnaire about several admission methods. General favorability, ratings on justice dimensions, relationships between general favorability and these dimensions, and differences in perceptions based on gender and on the aim of the admission procedure (selection or matching) were studied. In addition, the relationship between favorability and test performance, and the relationship between favorability and behavioral outcomes were investigated. Applicants rated interviews and trial‐studying tests most favorably. Contrary to expectations based on the existing literature, high school grades were perceived least favorably and there was no relationship between applicant perceptions and enrollment decisions. In line with previous research in the employment literature, general favorability was most strongly related to face validity, study‐relatedness, applicant differentiation, the chance to show skills, perceived scientific evidence, and perceived wide‐spread use. We found no differences in applicant perceptions based on gender and small differences based on the aim of admission procedures. These results extend the applicant perceptions literature to educational admission and the results are useful for administrators when choosing methods to admit students.     

Delving into the ‘emotional storms’: A thematic analysis of psychoanalysts’ initial consultation reports

Psychoanalysts’ written reports on initial consultations are a window into the complexities of a crucial aspect of psychoanalytic work. However, systematic research in this area has largely focused on patients’ demographic factors or standardized measures. The present study looked at reports of all the consultations taking place at the London Clinic of Psychoanalysis over one calendar year (N = 100). The aim was to explore psychoanalysts’ different explicit styles of working and reporting as well as further understanding implicit processes used in thinking and writing about each particular consultation experience. A thematic analysis revealed a set of themes that related to a style of working and thinking about the consultation process as a dyadic experience, where the interaction, affective reactions and contact made between the two are the focus when thinking of making a recommendation for psychoanalysis. The majority of the reports had an open, exploratory quality. The writing of reports appears to give the analyst an opportunity to process the consultation experience and arrive at a more triangular position. Writing reports is a more valuable part of the consultation process than has formally been recognized and acknowledged. The limitations of this study as well as the relevance of these findings for future research are discussed.     

Effects of a School‐Based Life Skills and HIV‐Prevention Program for Adolescents in Mexican High Schools1

A school‐based life skills and sexuality education HIV/AIDS program for adolescents was evaluated in Toluca, Mexico, through a quasi‐experimental pre–post design with 1,566 cases, divided over a control group and an experimental group. Based on a previously tested path model, 3 levels of variables were included as a guide for the contents of the program: personal variables (self‐knowledge, self‐efficacy regarding condom use, and decision making), intervening variables (subjective norms about, knowledge about HIV/AIDS, and attitudes toward condoms), and outcome variables (communication on sexuality and intentions to use condoms). Evaluation was conducted following these categories. Significant increases in all of these variables recognized as precursors of safer sex were found in the experimental group.     

Training parents to help their children read: A randomized control trial

Background . Low levels of literacy and high levels of behaviour problems in middle childhood often co‐occur. These persistent difficulties pose a risk to academic and social development, leading to social exclusion in adulthood. Although parent‐training programmes have been shown to be effective in enabling parents to support their children's development, very few parent interventions offer a combination of behavioural and literacy training. Aims . This paper (1) reports on a prevention programme which aimed to tackle behaviour and literacy problems in children at the beginning of school, and (2) presents the effects of the intervention on children's literacy. Sample . One hundred and four 5‐ and 6‐year‐old children selected from eight schools in an inner city disadvantaged community in London participated in the intervention. Methods . This is a randomized control trial with pre‐ and post‐measurements designed to evaluate the effectiveness of an intervention. The behavioural intervention consisted of the ‘Incredible Years’ group parenting programme combined with a new programme designed to train parents to support their children's reading at home. Results . Analyses demonstrated a significant effect of the intervention on children's word reading and writing skills, as well as parents' use of reading strategies with their children. Conclusion . A structured multicomponent preventive package delivered with attention to fidelity can enable parents to support their children's reading at home and increase their literacy skills. Together with the improvement in child behaviour, these changes could improve the life chances of children in disadvantaged communities.     

Strength and vulnerability integration: a model of emotional well-being across adulthood

The following article presents the theoretical model of strength and vulnerability integration (SAVI) to explain factors that influence emotion regulation and emotional well-being across adulthood. The model posits that trajectories of adult development are marked by age-related enhancement in the use of strategies that serve to avoid or limit exposure to negative stimuli but by age-related vulnerabilities in situations that elicit high levels of sustained emotional arousal. When older adults avoid or reduce exposure to emotional distress, they often respond better than younger adults; when they experience high levels of sustained emotional arousal, however, age-related advantages in emotional well-being are attenuated, and older adults are hypothesized to have greater difficulties returning to homeostasis. SAVI provides a testable model to understand the literature on emotion and aging and to predict trajectories of emotional experience across the adult life span.
