This study tested 2 competing models of friends' influence on the development of delinquency in disruptive boys. In so diong, we examined whether highly disruptive, moderately diseuptive, moderately conforming, and highly conforming boys' delinquecy increased or decreased depeniding on their friends' characteristics. A sample of 868 boys was classified into the 4 groups according to teacher tating at ages 11 and 12. Each group was then subdivided by mutual friends' peer-rate aggressiveness-disturbance at the same ages: aggressive-disturbing friends, average friends, nonaggressive-nondisturbing friends, and no friends. Subgroups were mext compared on self-reported delinquency at age 13 while controlling for average self-reported delinquency and socioeconomic variables at ages 11 and 12. Results indicate that moderately disruptive boys with aggressivedisturbive friends were more delinquent at age 13 than other subgroups of moderately disruptive boys. Highly disrupitve and confroming boys, however, were unaffected by their friends' characteristics. We conclude that the results partially support each theoretical model, suggesting that both individual characteristics and deviant peer association might play causal roles. 相似文献

Identifying early precursors of body mass index (BMI) and sports participation represents an important concern from a public health perspective and can inform the development of preventive interventions. This article examines whether kindergarten child self‐regulation, as measured by classroom engagement and behavioral regulation, predicts healthy dispositions in fourth grade. To address this objective, secondary analyses were conducted using prospective‐longitudinal data from 966 children followed by the Quebec Longitudinal Study of Child Development. Self‐regulatory skills, including classroom engagement and behavioral regulation, were measured by kindergarten teachers. Greater self‐regulatory skills predicted lower BMI and greater parent‐reported child sports participation, after controlling for a number of potentially confounding child and family characteristics. This article suggests that assessing kindergarten self‐regulatory capacities may help identify children at risk of developing unhealthy dispositions and behaviors in middle childhood. 相似文献

We study the benefits of junior kindergarten for linguistic-minority 4-year-olds compared to their linguistic-majority classmates from the same low-income neighborhoods. At the end of the school year, linguistic-minority children made significantly greater improvements in language skills than their host society classmates. At the mid-year point, junior kindergarten teachers made efforts to help linguistic-minority children overcome the challenges of the school environment of their new host society by adapting their pedagogical strategies to those showing difficulty in their receptive vocabulary skills. They also offered greater means of contact to parents of linguistic-minority children having difficulty attaining language proficiency than to parents of children showing better improvements. Parents of linguistic-minority students showing smaller gains were more likely to use a larger proportion of the communication methods offered by teachers and participate in the parent–school relationship for the well-being of their children. Long-term results suggest that linguistic-minority children continued to make significant improvements.

Digital skills are increasingly important for labour market outcomes and social participation. Do they also matter for academic performance? This paper investigates the effects of digital literacy on educational outcomes by merging data from the Italian National Assessment in secondary schools with an original data-set on performance tests of Internet skills for tenth-grade students. Our identification strategy relies on a rich set of individual, family, school and classroom control variables that are not commonly available in previous studies. The findings indicate that, overall, Internet skills have a positive impact on academic achievement. This effect is stronger for students with low academic performance or low family background. It is also stronger for students in technical or vocational schools. 相似文献

In this study, we examine whether preventive enrichment of pre-math skills has an influence on number knowledge in preschool children from low income families. Our data analyses use two methods to examine the influence of two independent programs implemented during junior kindergarten and kindergarten. The first implies the traditional approach comparing the self-selected treated group to a self-selected comparison group. The second approach uses a self-selected dosage approach to the treatment condition, considering that implementation of the program varied across teachers. The results regarding the enrichment program in kindergarten were inconclusive. Nevertheless, the pre-math program implemented in junior kindergarten showed a positive influence on children’s core requisite skills for later learning of arithmetic. Although children were receptive during both preschool years, a junior kindergarten program that elaborates upon conceptual issues beyond the number line appears both feasible and beneficial over the short-term. 相似文献

Abstract Between 1996 and 2001 over $13 trillion dollars was invested in information and telecommunications industries based on the vision of expanding markets and a pro competitive law know as the Telecommunications Act of 1996 ("'96 Act"). Since 2001 investment has substantially shrunk along with expectations about growth and new opportunities in converging information, communications and entertainment ("ICE") industries. This paper identifies how stakeholders and governments made false assumptions about the near term future of telecommunications demand and the prospects for seamless convergence of information and telecommunications technologies and markets. The paper provides suggestions on how national legislatures and regulators should respond to current circumstances. 相似文献

We study the art market in the Venetian Republic from 1550 to 1750 analyzing the determinants of the prices (adjusted for the cost of living measured by the price of wheat) of figurative paintings. Reputation of the painters, size of the paintings and other quantifiable factors affect prices as expected. Other relevant factors include the placement of the paintings (on altars, ceilings or walls), whose impact reflects differences in demand elasticities. We find evidence of the law of one price confirming price equalization between high and low demand geographical destinations and between different subjects. Finally, in a Schumpeterian perspective, we relate the temporal trend of the price of a representative painting with waves of artistic innovations, whose peacks were in the 1500s and in the 1700s with a dark Baroque age in the intermediate century. 相似文献
