Multi-objective combinatorial optimization problems: A survey

In the last 20 years many multi-objective linear programming (MOLP) methods with continuous variables have been developed. However, in many real-world applications discrete variables must be introduced. It is well known that MOLP problems with discrete variables can have special difficulties and so cannot be solved by simply combining discrete programming methods and multi-objective programming methods. The present paper is intended to review the existing literature on multi-objective combinatorial optimization (MOCO) problems. Various classical combinatorial problems are examined in a multi-criteria framework. Some conclusions are drawn and directions for future research are suggested.     

Does cyberbullying predict internalizing problems and conduct problems when controlled for traditional bullying?

In this study, relations between cybervictimization and internalizing and conduct problems were analyzed while controlling for traditional victimization. A sample of 701 emerging adults in secondary vocational education completed self-reports about cybervictimization, traditional victimization, internalizing problems and conduct problems. Using multiple regression analyses with heteroscedasticity-consistent estimates, it was found that cybervictimization is related to internalizing and conduct problems while controlling for traditional victimization. The results suggest that cybervictimization is related to both internalizing and conduct problems over and above traditional victimization. The discussion focuses on the need to address bullying and cyberbullying among emerging adults.

Reactive temperament traits and behavioural problems in children: the mediating role of effortful control across sex and age

This study examines the mediating role of effortful control between reactive temperament traits (negative affectivity and extraversion) and children’s internalizing and externalizing behavioural problems. The sample was composed of 424 non-clinical children from 3 to 6 years of age (60% male). Use of a structural equation model revealed effortful control-mediated relations between reactive temperament traits and behavioural problems. Nevertheless, uniquely and directly, negative affect predicted externalizing problems and extraversion predicted internalizing problems. Assessment of invariance by children’s sex showed that the mediating role of effortful control tends to be stronger for externalizing problems in boys than in girls. Results showed no significant age differences. According to these results, effortful control as a method of self-regulation seems to be an essential process through which reactive temperament traits affect a child’s psychological adjustment.     

Social decision making mediates the association between anger and externalising problems in Chinese adolescents

The goal of this study was to test the mediating effect of social decision making in the relations of anger and anger control to externalising and internalising problems. A sample of 174 Chinese adolescents (mean age = 15.36 years) completed self‐reports of trait anger, anger control, externalising problems, internalising problems and social decision making, which was operationalized as situational judgement reflecting an individual's ability to interact effectively with parents, teachers and peers. Findings indicated that adolescents' trait anger and anger control were positively related to both externalising and internalising problems. In addition, path analysis revealed that social decision making mediated the relationship between trait anger, anger control and externalising problems. Findings on the mediating effect will be discussed by referencing appraisal tendency theory and response evaluation and decision.

Assessment of incarcerated juvenile delinquents: Agreement across raters and approaches to psychopathology

The purpose of the current study was to examine the agreement across three informants (youth, teacher, caretaker) when rating behaviors of incarcerated juvenile delinquents. Furthermore, the agreement between a dimensional approach (Child Behavior Checklist) and a categorical approach (DSM-III-R) of assessing behavior was examined. Fifty-two delinquent youth were assessed with a structured interview. In addition, the youth, teacher, and caretaker completed the Child Behavior Checklist (CBCL). The results indicated significant correlations across the teacher and caretaker for externalizing types of problems. The youth report form of the CBCL did not correspond to either adult informant. However, the ratings by the teacher and caretaker were related to externalizing types of problems, primarily hyperactivity/inattention, derived from the structured interview with the delinquent. The results suggest that, in the psychological assessment of incarcerated juvenile delinquents, agreement across informants is dependent on multiple factors, including type of behavior assessed and the approach utilized in assessment.This work was supported, in part, by the Juvenile Justice Coordinating Council of Georgia, the Office of Juvenile Justice and Delinquency Prevention, and the University of Georgia's Institute for Behavioral Research.     

No indication that the ego depletion manipulation can affect insight: a comment on DeCaro and Van Stockum (2018)

Abstract

Recently, DeCaro and Van Stockum have suggested that ego depletion following intensive self-control can improve insight problem-solving; this finding was interpreted in terms of insight relying on decreased control over attention and memory. However, DeCaro and Van Stockum used three variants of the single matchstick arithmetic problem. Experiment 1 involved low sample and non-standard problem application, while the more powered Experiment 2 yielded a surprisingly low solution rate. These facts made both studies problematic and called for their replication. In the two present studies, the DeCaro and Van Stockum ego-depletion manipulation and their matchstick problems were administered to a total of 316 people. Furthermore, various other insight problems, subjective ratings of insight experience, analytical problems and executive control tests were applied. The key result was that no reliable effect of ego depletion could be found for any of these measures.     

Choosing or Being Chosen by Aggressive–Disruptive Peers: Do They Contribute to Children's Externalizing and Internalizing Problems?

The goal of this study was to investigate the extent to which aggressive-disruptive peers contribute to the development of externalizing and internalizing problems in children, while controlling for children's own behavior. We examined 2 sets of peers: (1) those that the child nominated as friends, and (2) those that nominated the child as a friend. The participants were 236 boys and girls attending 3rd to 5th grade at the beginning of the study, who were followed over a period of 2 years. Results showed that choosing more aggressive peers on the nomination procedure was associated with more externalizing problems and self-reported depressive symptomatology over time. On the other hand, being liked by more aggressive children generally was not associated with elevated externalizing or internalizing problems.     

Behavior assessment system for children

The Behavior Assessment System for Children (BASC) is a well-designed and useful set of measures for the assessment and identification of school-age children with emotional disturbances and behavioral disorders. The BASC consists of five measures designed to gather information about a child or adolescent from a variety of sources (teachers, parents, direct observations, students, and historical records). In combining this information into an integrated system, the BASC uniquely attempts to provide a multidimensional understanding of a child. This review summarizes the technical qualities of the BASC and critiques its usefulness for practicing school psychologists. Although there are shortcomings, the BASC is made up of some of the best measures of their kind and represents an approach of choice for identifying children with emotional and behavioral disorders in schools.     

Does Dissociation Among Adolescents Predict Difficulties? A Panel Study in Japan

Dissociation has been reported to be associated with emotive-relational and behavioral difficulties; however, the temporal relationship between dissociation and these difficulties is unclear. Accordingly, this study investigated whether dissociation predicts difficulties (including emotional symptoms, conduct problems, hyperactivity, and peer problems) in adolescents. A two-wave cross-lagged panel study (Time 1: September–November 2016, Time 2: February–March 2017) was conducted among 1,773 Japanese junior high and high school students at two private schools (995 boys and 778 girls; M_age = 14.79 years at Time 1 and 15.09 years at Time 2). Dissociation was assessed using the Japanese version of the Adolescent Dissociative Experiences Scale and perceived difficulties were assessed via the Strengths and Difficulties Questionnaire. A cross-lagged effects model analysis indicated that high dissociation scores at Time 1 predicted high difficulties scores at Time 2. These findings suggest that dissociation could effectively predict difficulties in junior high and high school students. This study expands the field's understanding of the temporal relationship between behavioral problems and dissociation, which could help prevent problem behaviors.

The effect of classroom environment on problem behaviors: A twin study

Children's behavior problems, both internalizing and externalizing, are a function of both genetic and environmental influences. One potentially important environmental influence is the classroom environment. This study of 1941 monozygotic twin pairs examined whether children whose parents rated them as similarly high or low on a number of problem behaviors were rated in the same way by teachers when they were together versus separated in their classrooms at school. Results showed that twins in the same classrooms were rated by their teachers more similarly on each dimension of problem behavior than were twins who were separated into different classrooms, suggesting that the classroom environment is important in predicting differences between twins in terms of problem behaviors at school. In addition, parents' ratings of problem behaviors were lower for twins placed in the same classroom versus twins in different classrooms. Thus, there is reason to consider whether, at least during the early school years, parents should be allowed to make the decision to not separate twins at school.     

Exposure to Community Violence: Defining the Problem and Understanding the Consequences

Exposure to community violence has emerged as a major risk factor for the development of emotional and behavioral problems in children and adolescents. In the past decade, there has been a proliferation of research within the fields of medicine, sociology, and psychology documenting the rates and consequences of exposure to community violence. This interdisciplinary growth has led to a great deal of variability within the field of exposure to community violence, making it difficult to glean general conclusions regarding rates and impact of exposure. This review advances the current understanding of exposure to community violence by integrating findings across disciplines as well as reviewing the few studies that have provided initial explanatory information regarding mediators and moderators of the relationship between exposure to community violence and its associated outcomes.     

留守儿童情绪和行为问题特征的潜在类别分析：基于个体为中心的研究视角

对2288个留守儿童样本用儿童长处与困难问卷（SDQ）进行施测,并对他们的情绪和行为问题特征进行探索性的潜在类别分析,发现留守儿童的情绪和行为问题存在明显的分组特征。统计指标支持了3个潜类别的模型,根据3个潜在类别在问卷各条目上的条件概率特征分别定义为：“适应困难组”,“行为冲动组”和“良好适应组”,3个潜在类别所占全体样本的比例分别为32%、41%和27%。进一步的分析发现：相比较良好适应组而言,适应困难组和行为冲动组有着显著的性别和年级水平效应,适应困难组和行为冲动组的男生所占比例更大;同时,这两个组的小学生所占的比例也更大。     

Parenting contributors to early emerging problem behaviour in children of mothers in methadone maintenance treatment

This study explored whether variations in parenting provided by mothers with substance‐abuse disorders are related to behaviour problems in their young children and whether specific parenting practices are associated with specific types of behaviour problems. Mother‐reported and observational assessments were used to examine contributions of parenting behaviour and home environment to internalizing and externalizing behaviour problems in 150 preschool children of mothers receiving methadone‐maintenance treatment for heroin addiction. In multivariate analyses, mother‐reported child externalizing behaviour was related to greater maternal harshness and to mother history of illicit drug use during pregnancy but not other features of substance use and treatment history. Observer‐coded child internalizing behaviour was related to less maternal sensitivity and less provision of learning activities in the home. Additionally, mother report of her own psychopathology symptoms was related to mother‐reported, but not observer‐coded, child internalizing and externalizing problems. Findings suggest that women in substance abuse treatment should receive parenting interventions and that interventions should focus on increasing maternal sensitivity, reducing harshness, and providing children with cognitively stimulating environments. Findings also suggest that the need for attention to ongoing mental health problems of women in substance abuse treatment—both for their own well‐being and the well‐being of their children.

Highlights

• This study explored whether variations in parenting provided by mothers with substance‐abuse disorders are related to behavior problems in their young children.
• Maternal harshness was related to child externalizing behavior, low sensitivity, and low provision of learning opportunities to child internalizing problems.
• Findings suggest that women in substance abuse treatment should be provided access to parenting interventions.

     

Exploring Violence Exposure, Stress, Protective Factors and Behavioral Problems Among Inner-City Youth

This study examined relationships between violence exposure, other stressors, family support, and self-concept on self-reported behavioral problems among 320 urban adolescents (aged 11–18) referred for mental health treatment. Overall, participants reported high levels of violence exposure, with a median of six past encounters with violence as a witness, victim, or through the experiences of associates. All forms of violence exposure (witnessing, being a victim, knowing of victims) were correlated with internalizing and externalizing behavioral problems for males and females. Total violence exposure predicted behavioral problems among participants, even after controlling for the effects of other risk, demographic and protective factors. Family support and self-concept moderated the influence of life stress and cumulative risk on problem behavior outcomes, but these protective variables did not significantly moderate violence exposure.
