The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.

Different paths to protest: predictors of collective action in the Occupy Movement

This study investigated the variables that shaped people's willingness to engage in collective action in the context of the Occupy Movement. Data were collected in 2011 from nonprotesting supporters at the New York City Occupy encampment and active occupiers at the New York and Atlanta encampments. Participants distinguished between different kinds of collective action based on cost. Furthermore, different predictors motivated distinct kinds of collective action. Identity and anger predicted low‐cost collective action. Efficacy predicted relatively costly collective action and mediated the link between identity and costly collective action. This study provides evidence that people draw distinctions between different actions based on cost and that, when it comes to predicting collective action, these distinctions matter.     

Joint Maximum Likelihood Estimation for Diagnostic Classification Models

Joint maximum likelihood estimation (JMLE) is developed for diagnostic classification models (DCMs). JMLE has been barely used in Psychometrics because JMLE parameter estimators typically lack statistical consistency. The JMLE procedure presented here resolves the consistency issue by incorporating an external, statistically consistent estimator of examinees’ proficiency class membership into the joint likelihood function, which subsequently allows for the construction of item parameter estimators that also have the consistency property. Consistency of the JMLE parameter estimators is established within the framework of general DCMs: The JMLE parameter estimators are derived for the Loglinear Cognitive Diagnosis Model (LCDM). Two consistency theorems are proven for the LCDM. Using the framework of general DCMs makes the results and proofs also applicable to DCMs that can be expressed as submodels of the LCDM. Simulation studies are reported for evaluating the performance of JMLE when used with tests of varying length and different numbers of attributes. As a practical application, JMLE is also used with “real world” educational data collected with a language proficiency test.     

Coping with Abusive Supervision: the Neutralizing Effects of Perceived Organizational Support and Political Skill on Employees’ Burnout

While research into the antecedents of burnout has steadily grown, the relationship between abusive supervision and burnout remains largely unknown. In addition, we know little about the contingencies under which abusive supervision may be related to employees’ burnout. This study aims to examine the contingency side of the abusive supervision-burnout relationship by addressing the exploratory question of whether perceived organizational support and individual differences in political skill play moderating roles in the abusive supervision-burnout relationship. The present article developed a model and tested it with data from a sample of 248 supervisor–subordinate dyads. We hypothesized and found that (1) Abusive supervision was positively associated with burnout; (2) the positive relationship between abusive supervision and burnout was moderated by the employees’ perceived organizational support in such a way that the relationship was weaker for employees who perceive higher rather than lower organizational support; (3) the positive relationship between abusive supervision and burnout was moderated by the employees’ political skill in such a way that the relationship was weaker for people with high, rather than lower level of political skill.     

Linking Maternal Socialization of Positive Emotions to Children’s Behavioral Problems: The Moderating Role of Self-Control

Little is known about how parents socialize children’s positive affect regulation during late childhood. Consequently, we examined how mothers’ reported responses to their children’s (aged 7–12 years) positive emotions were linked to children’s behavioral problems and how children’s self-control moderated these associations. Our results indicated that maternal encouragement of positive emotions predicted fewer externalizing behaviors, but only for youth with lower self-control. Maternal explanation about their children’s positive emotions was unrelated to youth’s behavioral problems. Lastly, maternal dismissing responses to their children’s positive emotions (i.e., reprimanding responses and discomfort) were related to more externalizing and internalizing in youth, and these effects were not dependent on the children’s self-control. The current study adds to the limited research on positive affect socialization and offers some evidence that youth’s self-control may serve as a vantage-sensitivity factor in the association between maternal positive affect socialization and youth adjustment.     

Nodule Detection with Eye Movements

Radiologists often miss nodules that may represent lung cancer on chest radiographs. We investigated whether eye movements collected during the search for lung nodules by large samples of laypeople may provide information that could assist radiologists in their detection. For that purpose, we developed a partially invisible Markov model with partially unobserved states and analyzed eye tracking data of over 100 laypeople who reviewed 14 chest X‐ray images, of which seven contained a potentially cancerous nodule. We used the luminance value of the pixels in the X‐ray images as prior information on the possible location of a nodule and identified six regions of interest on each image that may contain a nodule. Our study demonstrated that the eye movements recorded from laypersons contained information that may assist radiologists in the detection of nodules in chest X‐rays, which has important implications for crowdsourcing of search for pulmonary nodules, which are discussed.

Differences in the micromechanical properties of dendrites and interdendritic regions in superalloys

Statistical analysis of white-light interferometry (WLI) experiments performed on Ni-based single-crystal superalloys (SX) have revealed a different height distribution between the dendritic cores (DCs) and the interdendritic regions (IRs) of the polished samples. The micromechanical property difference is largely ascribed to the uneven distribution of the alloying elements. In this context, possible reasons for this difference are discussed by comparing with different experiment results obtained by previous researchers, and a proposal forecasting the hardness ratio of IRs/DCs is put forward.     

Internet Addiction and Well-Being: Daoist and Stoic Reflections

This article explores the phenomenon of Internet addiction and its possible amelioration, from both Eastern and Western philosophical perspectives. Internet addiction is caused by the excessive use of the Internet and its resulting dependence, having negative effects on human well-being. The ideas of a key ancient Chinese Daoist thinker Zhuangzi 莊子 and his Western contemporaries, the Stoics, as viewed through the world, the things and beings in it, and their relationships, offer insights which may be used to alleviate these effects. The application of and comparison between the two ancient philosophies in addressing the issue of Internet addiction can give us inspiration to confront the challenges of technological enslavement in general and Internet addiction in particular. This is no doubt a help in our pursuit of well-being.
