ORDANOVA: Analysis of ordinal variation

In order to accelerate object evaluation, some measurement systems commonly use an ordinal scale (e.g., stick results, quality estimation). This paper presents a way to analyze ordinal data variation. As in classical ANOVA for continual data, ORDANOVA for ordinal data splits the total variation into within and between components. This decomposition has various practical applications such as classification, cluster analysis, distinguishing feature identification and so on.     

Life satisfaction in the transition from care to adulthood: the contribution of readiness to leave care and social support

This research explores whether readiness to leave care mediates the association between social support – from peers, staff and biological parents – on the verge of leaving care and life satisfaction a year after among young people ageing out of care in Israel. The results represent two waves of a longitudinal study. Two hundred seventy‐two adolescents from residential settings in Israel completed a self‐administered questionnaire shortly before they left care, and one year later, 234 of them were interviewed to assess their life satisfaction. Readiness to leave care was found to mediate the relationship between most social support measurements and life satisfaction. At the same time, the findings also suggest that this mediating effect varies for different types of support and has a lesser amount of influence for profound emotional support than other types of support. These findings highlight the need to include both the preparation to leave care and the reinforcement of emotional support available to young people who aged out of care, before and throughout the transition from care to adulthood.     

Introduction to Improving Arab-Jewish Relations in Israel: Theory and Practice in Coexistence Educational Programs

Israeli Jewish and Arab experts within Israel have developed innovative intergroup relations programs, educational efforts designed to improve relations between Israeli Jews and Israeli Arabs. Social scientists, educators, and practitioners on both sides of the Arab-Jewish conflict have dedicated themselves to lessening the hostility between these two groups within Israel through coexistence educational training. This issue presents theory, methods, and data from these coexistence educational programs. The introductory article presents a brief history of this conflict; the groups' differing perceptions regarding the dispute; some information about the role of culture, socioeconomic status, and ethnicity in the discord; and some of the social psychological processes that perpetuate and recreate the hostilities. Last, it provides a brief preface of this issue's articles.     

Persistent symptoms of maternal post-traumatic stress following childbirth across the first months postpartum: Associations with perturbations in maternal behavior and infant avoidance of social gaze toward mother

Recent literature identifies childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth (PTS-FC). The current study examines whether stable symptoms of PTS-FC during the early postpartum period may impose risk for perturbations in maternal behavior and infant social-engagement with mother, controlling for comorbid postpartum internalizing symptoms. Mother-infant dyads (N = 192) were recruited from the general population, during the third trimester of pregnancy. 49.5% of the mothers were primipara, and 48.4% of the infants were girls. Maternal PTS-FC was assessed at 3-day, 1-month and 4-month postpartum, via self-report and clinician-administered interview. Latent Profile Analysis generated two profiles of symptomology: “Stable-High-PTS-FC” (17.0%), and “Stable-Low-PTS-FC” (83%). Membership in the “Stable-High-PTS-FC” profile associated with perturbed maternal sensitivity, which was in turn significantly associated with infant avoidance of social gaze toward mother (Indirect effect β = −0.15). Results suggest the need for early screening and inform the planning of early preventive interventions.     

A Bayesian meta-analysis of infants’ ability to perceive audio–visual congruence for speech

This paper quantifies the extent to which infants can perceive audio–visual congruence for speech information and assesses whether this ability changes with native language exposure over time. A hierarchical Bayesian robust regression model of 92 separate effect sizes extracted from 24 studies indicates a moderate effect size in a positive direction (0.35, CI [0.21: 0.50]). This result suggests that infants possess a robust ability to detect audio–visual congruence for speech. Moderator analyses, moreover, suggest that infants’ audio–visual matching ability for speech emerges at an early point in the process of language acquisition and remains stable for both native and non-native speech throughout early development. A sensitivity analysis of the meta-analytic data, however, indicates that a moderate publication bias for significant results could shift the lower credible interval to include null effects. Based on these findings, we outline recommendations for new lines of enquiry and suggest ways to improve the replicability of results in future investigations.
