This study examined relationships between caregivers' attachment, young children's emotion regulation, and aggression. Subjects were 110 institutionalized and 105 home-reared children (M=3.8 and 4.2 years, respectively). Data were collected from children's caregivers via questionnaires and analyzed by ANOVA, correlations, and hierarchical regressions. Results showed that (1) caregivers' attachment and the emotion regulation and aggression of institutionalized children were significantly different from those of home-reared children; (2) caregiver's attachment was positively related to emotion regulation for both institutionalized and home-reared children; (3) for institutional children, negative relationships between attachment and aggression was found for girls; negative relationships between emotion regulation and aggression was found for boys. These findings underscore negative effects of institutionalized care on children's socio-emotional behaviors.

This study quantifies the dynamic interrelationship between the KOSPI index return and search query data derived from the Naver DataLab. The empirical estimation using a bivariate GARCH model reveals that negative contemporaneous correlations between the stock return and the search frequency prevail during the sample period. Meanwhile, the search frequency has a negative association with the one-week- ahead stock return but not vice versa. In addition to identifying dynamic correlations, the paper also aims to serve as a test bed in which the existence of profitable trading strategies based on big data is explored. Specifically, the strategy interpreting the heightened investor attention as a negative signal for future returns appears to have been superior to the benchmark strategy in terms of the expected utility over wealth. This paper also demonstrates that the big data-based option trading strategy might be able to beat the market under certain conditions. These results highlight the possibility of big data as a potential source-which has been left largely untapped-for establishing profitable trading strategies as well as developing insights on stock market dynamics.

The combined impact of maternal depression, parenting stress, infant cry, and infant temperament on family functions was examined. The sample included 257 mothers in the near communities. Questionnaires completed by the mothers who had 0-36 month old children were used to measure depressive symptoms in mothers, infant cry, infant temperament, parenting stress, and family function. Maternal depression, parenting stress, infant crying and infant temperament had negative influence on family adaptability and family cohesion. Mother's depression had negative effect particularly on infant cry. Infant cry had positive effect on infant temperament. Infant temperament had high direct effect on parenting stress. As a result, it had negative influence on family function.

The main purpose of this paper is to estimate environmental preference of advanced countries for water and air pollution. In doing so, we introduce home production. That is, we assume that pollution has not only negative effect on utility but also positive effect on production. Thus if the former is greater that the latter effect, the total effect of pollution is negative. In this paper, we investigated this effect of advanced countries by using GMM estimator. The main finding is that in case of air pollution. This effect is negative. This implies that in case of air pollution, the disutility effect is greater that productivity effect.

This study investigated the behavior problems of children, both institutionalized and home-reared, depending on their sex, age, and entry to institution. The subjects included 621 children (274 institutionalized, 347 home-reared; 298 boys and 323 girls; 209 preschoolers, 223 first to third graders, 189 fourth to sixth). The data collected were analyzed with t-test, 3-way ANOVA, Scheffe test, and Pearson's correlation. Children's emotionality had two sides: Positive (happiness) and negative (sadness, anger, and fear). Measures of behavior problems included internalization (anxiety, immaturity, withdrawal, physical symptom) and externalization (hyperactivity, aggression). The results of this study indicated that the institutionalized were higher in negative emotionality than their counterparts, whereas the home-reared higher in positive emotionality. The institutionalized children also had higher externalizing problems than the home-reared. Furthermore, children's negative emotionality was positively related to their internalizing and externalizing behavior problems, while their positive emotionality was negatively related to the internalizing behavior problems.

The present research studied children's coping strategies by age, sex, and frequency of victimization and examined the relationship of coping strategies to loneliness in peer victimization. Participants were 434 children from the 3rd to 6th grades of an urban elementary school. Self-report data indicated seven types of coping strategies : cognitive distancing, adult support seeking, peer support seeking, negative problem solving, positive problem solving, internalizing, and externalizing. With increasing age, children used less adult support seeking and more positive problem solving. While girls used more adult and peer support seeking, boys employed more externalizing and negative problem solving. Children with higher victimization frequencies were more likely to use negative problem solving and internalization. Lack of strategies for seeking social support was associated with loneliness.

The purpose of study was to examine child emotion regulation as a function of child's sex, temperament, mother's emotion regulation, and mother's parenting. The subjects were 386 mothers of fifth or sixth graders in Seoul and Kyonggi province. The data were gathered through questionnaires developed for the current study. The major findings were as follows: 1) There were significant sex differences in some categories of child's emotion regulation. 2) The more active the child's temperament, the child showed more negative emotion regulation(venting, aggressive expression, avoidance). 3) Mother's negative emotion regulation was significantly related to the child's negative emotion regulation. 4) There were significant correlations between mother's parenting and child's emotion regulation. That is, mother's positive parenting was related to child's positive emotion regulation. 5) The relationship between mother's emotion regulation and child's emotion regulation was mediated by mothers' parenting.

For this study of adolescent attitudes toward child sexual abuse, 200 students attending high school and college participated in a group survey. The Child Sexual Abuse Myth Scale (Collings, 1999) was used to measure social attitudes toward child sexual abuse. Overall, the attitudes of the respondents placed between negative and positive attitudes. Nevertheless, strong negative myths and stereotypes, particularly blame diffusion, denial of abusiveness, and restrictive abuse stereotypes were found in specific situations. High school students and male students had more negative myths and stereotypes than college students and female students. Hierarchical regression analysis indicated the variables of education level and gender as the most important predictors in explaining students' attitudes toward child sexual abuse.

This study examined the effects of emotion inducing contexts on types of infants smiling. Facial expressions of forty-five 11-to 15-month-old infants were videotaped in an experimental lab with positive and negative emotional contests. Infants' smiling was identified as the Duchenne smile or non-Duchenne smile based on FACS(Facial Action Coding System, Ekman & Friesen, 1978). Duration of smiling types was analyzed. Overall, infants showed more smiling in the positive than in the negative emotional context. Occurrence of Duchenne smiling was more likely in the positive than in the negative context and in the peek-a-boo than in the melody toy condition within the same positive context. Non-Duchenne smiling did not differ by context.

This study examined relations between infants' strategies for emotional regulation and maternal responsiveness. Fifty 24-month-olds were observed for six kinds of emotional regulation strategy during four negative emotion-eliciting tasks; their mothers were observed for five styles of maternal responsiveness during toy-centered free play. Infants used different strategies according to the kinds of negative emotioneliciting tasks; their strategies correlated with maternal responsive styles. In the anger-eliciting tasks, infants used "distraction" and "self soothing." In the fear-eliciting tasks, they used "avoidance" and "problem solving." Infants who received more negative feedback from their mothers used the "irritation" strategy. Infants who got received more positive feedback from their mother used the "getting reference" strategy.
