This study examined whether iron deficiency (ID) in infancy contributes to problem behaviors in adolescence through its influence on poor regulatory abilities in childhood. Chilean infants (N = 1,116) were studied when there was no national program for iron fortification (1991–1996), resulting in high rates of ID (28%) and iron‐deficiency anemia (IDA, 17%). Infants (54% male) were studied at childhood (Mage = 10 years) and adolescence (Mage = 14 years). IDA in infancy was related to excessive alcohol use and risky sexual behavior in adolescence through its effect on poor emotion regulation in childhood. Attentional control deficits at age 10 were also related to both infant IDA and heightened risk taking in adolescence. Findings elucidate how poor childhood regulatory abilities associated with infant IDA compromise adjustment in adolescence. 相似文献

This study examined the strength of tracking sport participation from childhood to early adulthood among the Dunedin Multidisciplinary Health and Development Study cohort. Participation in sport, dance, or gymnastics as part of a club or group (outside of school) was assessed at ages 7, 9, 15, 18, and 21 years. In addition to the traditionally used correlation coefficients, summary statistics (intraclass correlations; ICC) from random effect models and stability coefficients from generalized estimating equations (GEE) were calculated using all the longitudinal data and controlling for the influence of covariates on tracking strength. Correlation coefficients revealed statistically significant tracking of club sport participation (7–21 years) at low levels (r = .07–0.28). The ICC summary statistic (0.23) was consistent with this, while the GEE suggested moderate tracking (0.59). The results of this study suggest that encouraging sport participation during childhood and adolescence may result in a modest increase in the likelihood of participation later in life. However, the substantial movement into and out of sport participation observed here and in other studies cautions against relying solely on sport promotion among youth as a strategy to promote lifelong participation. 相似文献

The extant studies have not empirically examined the possible team cognitive mechanisms that facilitate knowledge sharing in OSS teams, even though knowledge sharing is a cognitive task and an OSS team is a complex cognitive system. To fill this research gap, we adopt the perspective of transactive memory system (TMS) to explore the relationships among TMS, knowledge sharing, communication quality, and technical achievement of OSS teams. By analyzing data from 95 OSS projects with the partial least squares (PLS) method, our study demonstrates that several TMS dimensions have positive impacts on knowledge sharing behaviors and communication quality. Moreover, communication quality positively influences technical achievement of OSS teams. These findings provide useful implications for literature and practice. 相似文献

OBJECTIVE: The aim of this study was to determine whether reported childhood sexual abuse is related to the severity of symptoms in patients who experience auditory hallucinations. METHOD: A sample of 26 adult male and females with psychotic disorders involving auditory hallucinations were interviewed and were asked to complete three self-report measures: the Dissociative Experiences Scale (DES-II and DES-taxon versions); the Beck Depression Inventory (BDI); and the Beliefs About Voices Questionnaire (BAVQ). They were also asked about any history of sexual abuse in childhood. RESULTS: A history of childhood sexual abuse was reported by 10 of the 26 patients (38.5%), and was associated with higher levels of depression and dissociation, as well as being linked to a tendency to regard the voices as more malevolent. The same three features were all associated with the age at first reported abuse, with a younger age of first experience being related to higher levels of psychopathology in all instances. CONCLUSIONS: These results require replication and refinement in future research, but indicate a need for greater attention to be paid to the possible role of childhood sexual abuse when understanding and treating auditory hallucinations. 相似文献

This review was undertaken as part of a research project commissioned by the Scottish Executive and carried out by a team from Glasgow and Newcastle Universities between January 2000 and January 2001 when the report was published ( Banks et al., 2001 ). The research study, entitled 'Raising the Attainment of Pupils with Special Educational Needs', followed the issuing of new guidelines ( SOEID, 1998a ; SEED, 1999 ) which linked the use of individualised educational programmes (IEPs) to the wider political enterprise of raising standards through target-setting. 相似文献
