Bayesian Gaussian distributional regression models for more efficient norm estimation

A test score on a psychological test is usually expressed as a normed score, representing its position relative to test scores in a reference population. These typically depend on predictor(s) such as age. The test score distribution conditional on predictors is estimated using regression, which may need large normative samples to estimate the relationships between the predictor(s) and the distribution characteristics properly. In this study, we examine to what extent this burden can be alleviated by using prior information in the estimation of new norms with Bayesian Gaussian distributional regression. In a simulation study, we investigate to what extent this norm estimation is more efficient and how robust it is to prior model deviations. We varied the prior type, prior misspecification and sample size. In our simulated conditions, using a fixed effects prior resulted in more efficient norm estimation than a weakly informative prior as long as the prior misspecification was not age dependent. With the proposed method and reasonable prior information, the same norm precision can be achieved with a smaller normative sample, at least in empirical problems similar to our simulated conditions. This may help test developers to achieve cost-efficient high-quality norms. The method is illustrated using empirical normative data from the IDS-2 intelligence test.     

Hiring Rankings of Immigrant Job Applicants: Immigrants’ Acculturation Strategies and Managers’ Personality Trait Perception

This study examines how non-Western immigrants' acculturation strategies are related to managers' hiring rankings. It examines whether hiring managers differ in personality trait inferences depending on whether the candidate is a Turkish immigrant or a native Norwegian. Managers (N?=?436) evaluated three job applicants in terms of personality and hirability. Across three experimental conditions, the information of one (target) was manipulated and presented as either a native, as an integrated Turkish immigrant, and as a separated Turkish immigrant. The separated Turkish target received lower hirability rankings compared with the other target applicants. The integrated Turkish target was rated as more open, extraverted, conscientious, agreeable, and neurotic than the two other targets. Personality ratings of the Norwegian and the separated Turkish target did not differ significantly. Evaluations of personality were associated with hiring ranking of the Norwegian target only.     

A clusterwise simultaneous component method for capturing within‐cluster differences in component variances and correlations

This paper presents a clusterwise simultaneous component analysis for tracing structural differences and similarities between data of different groups of subjects. This model partitions the groups into a number of clusters according to the covariance structure of the data of each group and performs a simultaneous component analysis with invariant pattern restrictions (SCA‐P) for each cluster. These restrictions imply that the model allows for between‐group differences in the variances and the correlations of the cluster‐specific components. As such, clusterwise SCA‐P is more flexible than the earlier proposed clusterwise SCA‐ECP model, which imposed equal average cross‐products constraints on the component scores of the groups that belong to the same cluster. Using clusterwise SCA‐P, a finer‐grained, yet parsimonious picture of the group differences and similarities can be obtained. An algorithm for fitting clusterwise SCA‐P solutions is presented and its performance is evaluated by means of a simulation study. The value of the model for empirical research is illustrated with data from psychiatric diagnosis research.     

Sexual Harassment of Adolescents Perpetrated by Teachers and by Peers: An Exploration of the Dynamics of Power, Culture, and Gender in Secondary Schools

The purpose of this study was to explore and compare the similarities and disparities between sexual harassment of students that is perpetrated by teachers and by peers. The study involved 2,808 randomly selected adolescents at 22 secondary schools from two regions in the Netherlands. The sample comprised 14- and 15-year-old students (55% girls and 45% boys). The majority of the students' parents were born in the Netherlands (86%); 14% were born outside the Netherlands (Morocco, Turkey, and Surinam). The data revealed important differences between peer sexual harassment and sexual harassment perpetrated by teachers. Unwanted sexual behavior by peers is a cultural phenomenon that occurs in public areas. The relatively low incidence of unwanted sexual behavior (18%), however, does not fully reflect the Culture Model. Sexual harassment by teachers is a particularly detrimental experience for adolescents, and health-related problems are therefore reported in higher numbers. Contrary to the assumptions of the Power Model, sexual harassment perpetrated by teachers is not incidental (27%) and does not only occur in secluded places.     

How to detect which variables are causing differences in component structure among different groups

When comparing the component structures of a multitude of variables across different groups, the conclusion often is that the component structures are very similar in general and differ in a few variables only. Detecting such “outlying variables” is substantively interesting. Conversely, it can help to determine what is common across the groups. This article proposes and evaluates two formal detection heuristics to determine which variables are outlying, in a systematic and objective way. The heuristics are based on clusterwise simultaneous component analysis, which was recently presented as a useful tool for capturing the similarities and differences in component structures across groups. The heuristics are evaluated in a simulation study and illustrated using cross-cultural data on values.     

Temper, temperature, and temptation: heat-related retaliation in baseball

In this study, we analyzed data from 57,293 Major League Baseball games to test whether high temperatures interact with provocation to increase the likelihood that batters will be hit by a pitch. Controlling for a number of other variables, we conducted analyses showing that the probability of a pitcher hitting a batter increases sharply at high temperatures when more of the pitcher's teammates have been hit by the opposing team earlier in the game. We suggest that high temperatures increase retaliation by increasing hostile attributions when teammates are hit by a pitch and by lowering inhibitions against retaliation.     

Predicting Turnover with Broad and Narrow Personality Traits

The purpose of this study was to examine the relationship between personality and turnover and the relative validity of broad and narrow personality traits. At the domain level, Extraversion and Openness to Experience were positively correlated with turnover in a sample of 203 call center employees. Several facets were correlated with turnover after controlling for the corresponding domains.     

Adolescents' psychological health and experiences with unwanted sexual behavior at school

This paper examines the relationship between experiences with unwanted sexual behavior at school and adolescents' health. Adolescent boys and girls (N = 2,808) participated in a 1998/1999 survey of secondary school students in two regions of The Netherlands. The psychological issues investigated included psychosomatic problems and self-esteem. It was hypothesized that adolescents who have experienced unwanted sexual behavior at school would report more psychosomatic problems and lower self-esteem. Furthermore, it was hypothesized that girls would report lower self-esteem and more psychosomatic problems than would boys. Regression analysis indicated that experiences with unwanted sexual behavior were related to adolescents' psychological health, independently of other variables.     

Avoiding the Asymmetry Problem

If earlier‐than‐necessary death is bad because it deprives individuals of additional good life, then why isn't later‐than‐necessary conception bad for the same reason? Deprivationists have argued that prenatal non‐existence is not bad because it is impossible to be conceived earlier, but postmortem non‐existence is bad because it is possible to live longer. Call this the Impossibility Solution . In this paper, I demonstrate that the Impossibility Solution does not work by showing how it is possible to be conceived earlier in the same senses it is possible to live longer. I then offer a solution to the Asymmetry Problem by suggesting a novel way to separate the badness of each type of non‐existence from the type, and frequency, of attitudes we should have towards each type of non‐existence. Even if both types of non‐existence are equally bad, certain contingent facts about our postmortem non‐existence provide reason for the badness of early deaths to be more frequently salient than the badness of late conceptions. 1 1 For helpful discussion and feedback on earlier drafts of this paper, I am grateful to Kurt Blankschaen, Ben Bradley, Yishai Cohen, Jenni Ernst, John Martin Fischer, Frederik Kaufman, Gerald Marsh, Jeff McMahan, Hille Paakkunainen, Derek Parfit, Doug Portmore, Nate Sharadin, David Sobel, and my audience at the University of Miami.

Emotion differentiation and its relation with emotional well-being in adolescents

Emotion differentiation (ED) refers to the precision with which people can identify and distinguish their emotions and has been associated with well-being in adults. This study investigated ED and its relation with emotional well-being (i.e. depressive symptoms, positivity and negativity intensity and propensity, implicit theories of emotions) in adolescents. We used an experience sampling method with 72 participants (M_age?=?14.00, 71% girls) to assess adolescents’ positive and negative emotions at different time points over the course of two weekends and a baseline questionnaire to assess emotional well-being. Differentiating negative emotions was related to less negativity intensity and propensity, and to the belief that emotions are malleable. Differentiating positive emotions was not related to any of the assessed well-being variables. Together, these results suggest that a detailed awareness of one’s negative emotional states is an important dimension of well-being, also in adolescence.
