Exposure to Parent and Peer Alcohol Use and the Risk of Drinking Onset and Escalation Among Adolescents

Although the rate of alcohol use among adolescents has declined, it remains their drug of choice. Parent and peer alcohol use are powerful risk factors for youth alcohol use. However, questions remain about how these factors influence underage drinking. The present study investigates the relationship between exposure to parent or peer alcohol use and two stages of adolescent drinking—onset and escalation—overall and at five age points during adolescence. Participants were 9348 adolescents in Waves I (WI) and II (WII) of the National Longitudinal Study of Adolescent Health, whose parents completed interviews at WI, and who identified themselves as either non-drinkers or experimental drinkers at WI. Reports of WII alcohol use were used to measure onset among WI non-drinkers and escalation among WI experimenters. Risk ratios were calculated to assess the overall impact of exposure to parent or peer alcohol use on onset and escalation, and at five age points (i.e., ≤?13, 14, 15, 16, and ≥?17). Findings show that exposure to either parent or friend alcohol use increased the risk of onset and escalation. Age-based analyses reveal a more nuanced relationship, showing variability in the nature and strength of influence by stage of drinking and by age. This study highlights the relevance of both parent and peer modeling on youth drinking throughout adolescence. Implications in advancing prevention and treatment include parental education about the impact of their own behaviors and the importance of monitoring teens’ friendships.     

An analysis of the encoding and decoding of spontaneous and posed smiles: The use of facial electromyography

Twenty subjects judged 80 video segments containing brief episodes of smiling behavior for expression intensity and happiness of the stimulus person. The video records were produced under instructions to (a) pose, (b) experience a happy feeling or (c) to both experience and show a happy feeling. An analysis of the integrated facial electromyogram (EMG), recorded over four muscle regions (zygomaticus major, depressor anguli oris, corrugator supercilii, andmasseter), showed that judgments of happiness and of intensity of expression could be predicted in a multiple regression analysis (multipleR = .64 for perceived happiness and .79 for perceived expression intensity). The perception of happiness was affected by EMG activity in regions other thanzygomaticus major. The use of parameters other than the mean of the integrated EMG, namely variance, skewness, kurtosis and properties of the amplitude distributions across time, provided accurate classification of the elicitation conditions (pose happiness versus experience happiness) in a discriminant analysis. For the discrimination of posed and felt smiles variables describing aspects of facial activity in the temporal domain were more useful than any of the other measures. It is suggested that facial EMG can be a useful tool in the analysis of both the encoding and decoding of expressive behavior. The results indicate the advantage of using multiple-site EMG recordings as well as of using amplitude and temporal characteristics of the facial EMG measures.The research was supported in part by funds associated with the John Sloan Dickey Third Century Professorship (Kleck) and in part by grant BNS-8507600 from the National Science Foundation (Lanzetta).

Selbstreflexivität – Annäherungen an eine zentrale Haltung in Coaching- und Beratungsprozessen

This article explores “self-reflexivity” as a key competence and general attitude in all contexts of coaching and supervision. Three main perspectives are used approaching self-reflexivity: the “where from”, “what for” and “how-to”. Thus starting from etymology the importance of the subject in the practice of coaches and counselors is explored. Based on two models it is shown what kind of interaction between client and coach is beneficial when wanting to activate self-reflexivity. The article is rounded up by a note on self-care—one important aspect of self-reflexivity.     

Die Entwicklung von Organisations- und Teamstrukturen zur Integration von Flüchtlingen: Zwei Fallbeispiele aus der SchweizThe development of organization and team structures in institutions for refugee integration: Two examples from Switzerland

The article is concerned with the organizational and team-related challenges of integration of refugees in Switzerland from the perspective of the actors in organizations who assume this task in their daily work. Based on interviews with employees of the Zürcher Fachorganisation AOZ and the Fachstelle Integration Graubünden the development and functionality of different organizational structures will be discussed and analyzed with regard to their adaptation to structural conditions of the region as well as specific requirements of the arriving refugees. Particular consideration is given to measures of social and professional integration. The two organizations were chosen because the former is well established in Switzerland and has been active in the integration of refugees for more than 30 years and the latter has been particularly successful in assisting refugees to get a placement in the primary labor market. Numerous challenges of newly arriving refugees in Switzerland require different targeted services (language training, cultural integration, psychological support, etc.). In order to meet these requirements coordinated, balanced team structures are required. The results show that the two organizations differ considerably in their structure, distribution of tasks and integration into networks despite almost identical remits.     

The Goldilocks principle: applying the exclusive disjunction to fuzzy sets

Qualitative Comparative Analysis (QCA), a technique by which the tools of Boolean algebra are applied to equifinal causal conditions, is gaining popularity amongst scholars. This paper draws upon a distinction largely overlooked by the QCA literature: the difference between inclusive- and exclusive-or (OR and XOR). I argue that XOR should be included amongst the tools of QCA, explain why XOR is more easily applied to crisp- than fuzzy-set QCA, and provide two original techniques for applying XOR to fuzzy sets: mechanical and calibrated. With the calibrated technique, the application of the exclusive-or is related to substantive knowledge of the cases with two threshold values: (1) how large two fuzzy set values need to be in order to violate a prior commitment or overshoot a target outcome, and (2) how similar two values need to be in order to violate the rule: ‘A or B, but not both’. This paper improves the capacity of QCA expressions to mirror natural language closely, formalize conversational implicature, and deal with mutually exclusive clusters of sufficiency conditions. It includes a helpful step-by-step guide for QCA practitioners.

The Intensity of Emotional Facial Expressions and Decoding Accuracy

The influence of the physical intensity of emotional facial expressions on perceived intensity and emotion category decoding accuracy was assessed for expressions of anger, disgust, sadness, and happiness. The facial expressions of two men and two women posing each of the four emotions were used as stimuli. Six different levels of intensity of expression were created for each pose using a graphics morphing program. Twelve men and 12 women rated each of the 96 stimuli for perceived intensity of the underlying emotion and for the qualitative nature of the emotion expressed. The results revealed that perceived intensity varied linearly with the manipulated physical intensity of the expression. Emotion category decoding accuracy varied largely linearly with the manipulated physical intensity of the expression for expressions of anger, disgust, and sadness. For the happiness expressions only, the findings were consistent with a categorical judgment process. Sex of encoder produced significant effects for both dependent measures. These effects remained even after possible gender differences in encoding were controlled for, suggesting a perceptual bias on the part of the decoders.     

Estimating the error variance in nonparametric regression by a covariate-matched u-statistic

For nonparametric regression models with fixed and random design, two classes of estimators for the error variance have been introduced: second sample moments based on residuals from a nonparametric fit, and difference-based estimators. The former are asymptotically optimal but require estimating the regression function; the latter are simple but have larger asymptotic variance. For nonparametric regression models with random covariates, we introduce a class of estimators for the error variance that are related to difference-based estimators: covariate-matched U-statistics. We give conditions on the random weights involved that lead to asymptotically optimal estimators of the error variance. Our explicit construction of the weights uses a kernel estimator for the covariate density.     

Assessing the Ability to Recognize Facial and Vocal Expressions of Emotion: Construction and Validation of the Emotion Recognition Index

Despite extensive research on emotional expression, there are few validated tests of individual differences in emotion recognition competence (generally considered as part of nonverbal sensitivity and emotional intelligence). This paper reports the development of a rapid test of emotion recognition ability, the Emotion Recognition Index (ERI), consisting of two subtests: one for facial and one for vocal emotion recognition. The rationale underlying the test’s construction, item selection, and analysis are described and a major validation study with more than 3,500 professional candidates, providing stable norms, is reported. Additional analyses concern differences for gender, age, and education, as well as correlations with cognitive intelligence and personality factors. Moreover, a separate validation study with a student sample reports the correlations of the ERI with some of the major published tests in this area, demonstrating satisfactory construct validity. Correlations between ERI scores and the position of candidates in the organizational hierarchy suggest that recognition competence might be might contribute to predicting career advancement.
