Childhood adversity and the risk of substance use and delinquency: The role of protective adult relationships     

《Child abuse & neglect》2017

Youth involved in the child welfare system experience multiple early adversities that can contribute to increased risk of substance use and delinquency. Although adverse childhood experiences (ACEs) have been associated with poorer behavioral outcomes among youth, less is known about the possible protective factors that may influence the relationship between early adversity and risk-taking behavior. This study examined whether protective adult relationships moderated the link between cumulative ACEs and substance use and delinquency after controlling for demographic characteristics in child welfare-involved youth. The sample included 1054 youth, ages 11–17, from the National Survey of Child and Adolescent Well-Being II who were in the first wave of data collection. Results showed that protective adult relationships moderated the relationship between ACEs and substance use, but not for delinquency. Specifically, under lower levels of protective adult relationships, cumulative ACEs related to increased substance use among youth. Implications for child welfare practices to target youths' support systems are discussed.  相似文献   

Teachers' perspectives of changes in their practice during a technology in mathematics education research project     

《Teaching and Teacher Education》2017

Teachers' perception of changes to their teaching practice, with respect to digital technology use in secondary school mathematics, during their participation in a research project are reported. Two case studies are presented of teacher perspectives illustrative of the range of perceived changes teachers made to their practice and positions along the ‘path of change’ during their participation in the project. Participating in a project supportive of teacher change and resulting in perception of substantial change was necessary, but not sufficient, to meet the goal of transformative use of digital technologies to increase the level of cognitive demand experienced by students.  相似文献   

关于深化国有资源有偿使用制度改革的理论初探     

武心英 《连云港职业技术学院学报》2007,20(2):43-45

在粗放型的经济增长方式下，由于我们过多地运用了行政手段来管理经济，管理国有自然资源，导致国有自然资源一直是无偿或低廉使用的。随着我国经济增长方式的根本性转变，国有资产无偿使用制度的弊端已显现，一是导致国有自然资源的收益大量流失；二是导致国有资源配置无序和扭曲。因此，深化国有资源的有偿使用制度改革，对于维护国有资源的权益，加强资源开发者的经济责任，实现资源的最优配置，加速与国际通行做法的并轨，具有极为重要的现实意义，有广为实行之必要。  相似文献

植物生长调节剂在作物生产中的安全使用   总被引：5，自引：0，他引：5  

王小兰 《甘肃广播电视大学学报》2005,15(3):1-4

植物生长调节剂已广泛应用于农作物生产中，能有效改善作物生长状况，提高产品产量和品质，但使用不当也会造成严重的药害。在实际生产中要注意安全使用植物生长调节剂，根据作物品种和使用目标，来选择植物生长调节剂的类型，严格控制浓度及施用方法、时间和次数，从而充分发挥植物生长调节剂的效果。  相似文献   

人格特征和互联网使用     

柳铭心  雷雳 《首都师范大学学报(社会科学版)》2006,(3):111-115

互联网具有传统多媒体的特性,又具有强大的交互性,而这种交互性因它的匿名性、隐形性等特点又不同于现实中的面对面的人际交往和生活方式。正是这种不同,使具有不同人格倾向的使用者在选择自己需要的互联网服务的同时,其人格也受到了互联网的影响。文章介绍了“人格与互联网”研究中两个方面的研究进展:其一,人格倾向对选择互联网服务的作用;其二,互联网对个体人格倾向的影响。并指出了当前研究中存在的问题和未来研究可以拓展的方向。  相似文献   

Using Google Forms to track library space usage     

Beth Daniel Lindsay 《Journal Of Access Services》2016,13(3):159-165

This article is a response to the excellent “Using Mobile Technology to Observe Student Study Behaviors and Track Library Space Usage” by Susan Thompson. Thompson reviews the literature regarding user counts on mobile devices and describes the California State University San Marcos (CSUSM) Library's evaluation of SUMA, Counter+, and CloudOn. After trialing these mobile technologies, CSUSM selected CloudOn. At New York University Abu Dhabi, we use Google Forms to conduct user counts on an iPad and Google Sheets to evaluate these data. We find that Google Forms are easy to set up, modify as necessary, and present the data in easy-to-manipulate spreadsheets.  相似文献
