Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability.  相似文献

The current article seeks to add to the quantitative approach to understanding terrorism by examining the logic underlying terrorist choice of targets and timing within the context of the Chechen–Russian conflict. Using data on Chechen rebel bombings in Chechnya and Russia from 1997–2003, the analysis revealed support for a logic underlying terrorist choice of targets. The results indicated that civilian targets were more likely to be targeted in Russia than in Chechnya, illustrating the importance of examining contextual effects within quantitative approaches to terrorism. The results also implicated an affect of weather and urbanization. Implications of the results and future directions for research are discussed.  相似文献

This article is based on the results of a survey carried out in 2019 to document health managers and professionals’ knowledge concerning their linguistic obligations and the tools promoting active offer in the field of mental health in French, in Ontario and Manitoba. The working hypothesis is that knowledge of the obligations and available tools can contribute to a successful offer of services in French. The more professionals and managers understand their obligations, the more tools they can use to fulfill them. The study shows that there is indeed a link between knowledge of obligations and the use of tools to provide an active offer of mental health services in French. It also highlights the key role of tools to provide French services actively.  相似文献

The ascendency of immigration as an issue in elections has been concomitant with massive increases in the Hispanic population in the U.S. We examine how immigration cues prompt greater or lesser levels of restrictionist sentiment among individuals, showing demographic context conditions the effect of candidates cues. Using data from the 2010 U.S. House elections, we illustrate cues presented in new destination states—states with massive increases in the size of the Hispanic population from 1990 to 2010—have a larger impact on individuals’ immigration preferences than cues presented in non-new destination contexts. We show candidates with more extreme immigration positions are more likely to prioritize the issue of immigration in their campaigns, suggesting campaign prioritization of immigration has a directional cue. We conclude these directional cues from Republican candidates in new destination contexts move individual attitudes toward restrictionist preferences.  相似文献
