Relationships Between Social Support,Internal Assets,and Life Satisfaction in Korean Adolescents

In previous literature, social support has been reported to have a significant, positive relationship with life satisfaction. However, few studies have examined this relationship among Korean youths and how their psychological functioning is associated with both social support and life satisfaction. This study investigated the associations between different sources of social support (i.e., family, peer, and teacher), psychological factors (i.e., self-efficacy and emotional regulation), and life satisfaction, in a sample of 1133 Korean adolescents. The possibility of sex differences in these relationships was also investigated. Results indicated that only family support had a direct relationship with life satisfaction for male adolescents; however, all three types of social support were found to have a significant, indirect relationship with life satisfaction for male adolescents through both psychological factors. In contrast, all three types of social support had a direct relationship with life satisfaction of female adolescents. Additionally, self-efficacy had a mediating effect on the relationship between the social support from family and teachers and life satisfaction of female adolescents. The results and implications of the study are discussed.     

The learning benefits of teaching: A retrieval practice hypothesis

Teaching educational materials to others enhances the teacher's own learning of those to‐be‐taught materials, although the underlying mechanisms remain largely unknown. Here, we show that the learning‐by‐teaching benefit is possibly a retrieval benefit. Learners (a) solved arithmetic problems (i.e., they neither taught nor retrieved; control group), (b) taught without relying on teaching notes (i.e., they had to retrieve the materials while teaching; teaching group), (c) taught with teaching notes (i.e., they did not retrieve the materials while teaching; teaching without retrieval practice [TnRP] group), or (d) retrieved (i.e., they did not teach but only practised retrieving; retrieval practice group). In a final comprehension test 1 week later, learners in the teaching group, as did those in the retrieval practice group, outperformed learners in the TnRP and control groups. Retrieval practice possibly causes the learning benefits of teaching.     

Relations between virtues and positive mental health in a Korean population: A Multiple Indicators Multiple Causes (MIMIC) model approach

A Multiple Indicators Multiple Causes (MIMIC) approach was applied to investigate the relationship between virtues and positive mental health as determined using the Character Strength Test and the Mental Health Continuum‐Short Form. The study participants were 876 college students (54% women; overall mean age [SD] 21.50 years [2.35]) recruited from introductory psychology courses at two universities in Seoul. Findings revealed that the intellectual virtues of college students predicted subjective well‐being according to all emotional, social and psychological measures. Results are discussed in the context of previous work using the Values in Action classification of virtues and character strengths. In addition, implications regarding understanding the nature and possible origins of positive mental health are outlined.     

Balance between volunteer work and family roles: Testing a theoretical model of work‐family conflict in the volunteer emergency services

Trends indicate overall declines in numbers of volunteer emergency service workers and suggest negative organisational factors impacting adversely on volunteers and organisations. Conflict between emergency service work and family is implicated in falling volunteer numbers, and there is thus a need for research on difficulties experienced in balancing volunteer work and family. The current study tested an adaptation of the work‐family conflict (WFC) model originally proposed by Frone, Russell, and Cooper, in a sample of 102 couples in which one partner was an Australian emergency service volunteer. Results supported a model in which volunteer work‐related antecedents, including time invested in on‐call emergency activities and post‐traumatic stress symptoms, had indirect links with outcomes, including volunteer burnout and their partners' support for the volunteer work role, through the effects of WFC. These results add to research using theoretical models of paid work processes to better understand the problems faced by volunteer workers, and identify specific antecedents and outcomes of WFC in the volunteer emergency services. Implications for future research and organisations reliant on volunteer workers are discussed.     

The Structural Relationships of Parenting Style,Creative Personality,and Loneliness

The purpose of this study was to examine the nature of the relationships between children's reports of their mother's and father's parenting style (leniency and acceptance), teacher's reports of children's creative personality, and teacher's reports of children's loneliness in school in a sample of South Korean sixth graders (N = 421). Using structural equation modeling, the results showed that parenting styles that reflected higher levels of leniency were associated with higher levels of loneliness and no relationship with children's creative personality. Parenting styles that reflected higher levels of acceptance were associated with higher levels of creativity in their children, but did not have a direct effect on loneliness. However, there was an indirect effect; the relationship between acceptance and loneliness was mediated by creativity.     

A Non-Verbal Technique for Assessing Frustration Response in Pre-School Children

The present study represents a report of the initial development of a picture method for assessing response to frustration in preschool children. Study 1 (N = 91) included the initial development of the picture materials; it also produced some validational support for the picture method in the form of significant correlations between picture choices and extensive behavior observations. Study 2 (N = 49) was designed to be essentially a replication of Study 1. In addition, further validational support was sought through the correlation of picture choices with global teacher ratings of the behaviors of interest.     

Associations between cortical thickness and general intelligence in children,adolescents and young adults

Neuroimaging research indicates that human intellectual ability is related to brain structure including the thickness of the cerebral cortex. Most studies indicate that general intelligence is positively associated with cortical thickness in areas of association cortex distributed throughout both brain hemispheres. In this study, we performed a cortical thickness mapping analysis on data from 182 healthy typically developing males and females ages 9 to 24 years to identify correlates of general intelligence (g) scores. To determine if these correlates also mediate associations of specific cognitive abilities with cortical thickness, we regressed specific cognitive test scores on g scores and analyzed the residuals with respect to cortical thickness. The effect of age on the association between cortical thickness and intelligence was examined. We found a widely distributed pattern of positive associations between cortical thickness and g scores, as derived from the first unrotated principal factor of a factor analysis of Wechsler Abbreviated Scale of Intelligence (WASI) subtest scores. After WASI specific cognitive subtest scores were regressed on g factor scores, the residual score variances did not correlate significantly with cortical thickness in the full sample with age covaried. When participants were grouped at the age median, significant positive associations of cortical thickness were obtained in the older group for g-residualized scores on Block Design (a measure of visual-motor integrative processing) while significant negative associations of cortical thickness were observed in the younger group for g-residualized Vocabulary scores. These results regarding correlates of general intelligence are concordant with the existing literature, while the findings from younger versus older subgroups have implications for future research on brain structural correlates of specific cognitive abilities, as well as the cognitive domain specificity of behavioral performance correlates of normative gray matter thinning during adolescence.     

Ethical Perceptions of Field Sales Personnel: An Empirical Assessment

Much research attention has been directed over the past twenty-five years to ethical issues in marketing. One area of marketing that is gaining research interest is the selling arena. Despite the extant literature on selling ethics, few studies have focused on identifying situations that pose ethical problems for field sales personnel. This paper reports results of an investigation that examined salespeople's perceptions concerning what selling situations or practices are ethical questions, what situations are presently addressed by company policies, and what situations should be addressed by company policies. Findings reveal that salespersons seemingly are desirous of receiving more management guidance than they currently are receiving regarding their ethical concerns. Implications for managers and researchers are provided.
