This study examined two possible mechanisms, evocative gene–environment correlation and prenatal factors, in accounting for child effects on parental negativity. Participants included 561 children adopted at birth, and their adoptive parents and birth parents within a prospective longitudinal adoption study. Findings indicated child effects on parental negativity, such that toddlers’ negative reactivity at 18 months was positively associated with adoptive parents’ over-reactive and hostile parenting at 27 months. Furthermore, we found that child effects on parental negativity were partially due to heritable (e.g., birth mother [BM] internalizing problems and substance use) and prenatal factors (e.g., BM illicit drug use during pregnancy) that influence children’s negative reactivity at 18 months. This study provides critical evidence for “child on parent” effects.  相似文献   

Effect of Twinning on Chinese and English Vocabulary Knowledge     

Simpson W.L. Wong  Him Cheung  Mo Zheng  Xiujie Yang  Catherine McBride  Connie Suk-Han Ho  Judy Sze-Man Leung  Bonnie Wing-Yin Chow  Mary Miu Yee Waye 《Child development》2020,91(6):1886-1897

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.  相似文献   

秦始皇兵马俑博物馆室内含硫颗粒物的SEM-EDX研究     

胡塔峰  曹军骥  李旭祥  董俊刚  沈振兴  Shun-Cheng Lee  Judith C.Chow  John G.Watson  容波 《中国科学院研究生院学报》2007,24(5):564-570

本文对秦始皇兵马俑博物馆室内采集的长短期降尘、大气悬浮颗粒物和彩绘漆层进行了SEM-EDX研究，在大气悬浮颗粒、短期和长期降尘中，含硫颗粒的粒径分别为0.9～22.8μm、1.0～29.0μm和1.2～37.7μm，多为石膏与粘土或石英以内部混合的状态存在。降尘中的附着型絮状硫酸钙多于大气悬浮颗粒物中，显示降尘和大气中的二氧化硫发生了累进的化学反应。彩绘漆层表面的坑和裂隙附近观察到原位生长的硫酸钙晶体，显示漆层材料或降尘颗粒物与大气二氧化硫之间的酸化学反应，可能是彩绘漆层表面受侵蚀形成微小坑和裂隙的原因之一。  相似文献

Online homework impact in undergraduate mathematics and business statistics courses     

Alan F. Chow 《Educational studies》2015,41(3):244-248

This evaluation examines the impact on student success rates related to changes in instructional programmes in undergraduate mathematics and statistics courses. Success for students taking courses with a computer-based homework component was compared with success of students who took the course in prior semesters without the computer-based component. Graphical and analytical tools are used to compare results. Results come from multiple semesters of each type of homework application, for both pre-calculus algebra and business statistics courses. Students whose performance is utilised in this study are undergraduate students taking introductory level college mathematics or business statistics courses, with mostly no prior instruction at this level. Comparing the success of the intervention group with the success of the baseline control group, findings support that the students using the computer-based homework instruction are just as successful as those using the traditional method of homework instruction. Utilising the online homework applications, provide several important advantages in today’s universities, including the reduced time for faculty grading, consistency of graded assignments across all sections of a course and most importantly, immediate feedback for students.  相似文献   

Community Level Factors and Child Maltreatment Rates   总被引：8，自引：1，他引：8  

Claudia J. Coulton  Jill E. Korbin  Marilyn Su  Julian Chow 《Child development》1995,66(5):1262-1276

Using census and administrative agency data for 177 urban census tracts, variation in rates of officially reported child maltreatment is found to be related to structural determinants of community social organization: economic and family resources, residential instability, household and age structure, and geographic proximity of neighborhoods to concentrated poverty. Furthermore, child maltreatment rates are found to be intercorrelated with other indicators of the breakdown of community social control and organization. These other indicators are similarly affected by the structural dimensions of neighborhood context. Children who live in neighborhoods that are characterized by poverty, excessive numbers of children per adult resident, population turnover, and the concentration of female-headed families are at highest risk of maltreatment. This analysis suggests that child maltreatment is but one manifestation of community social organization and that its occurrence is related to some of the same underlying macro-social conditions that foster other urban problems.  相似文献   

Creative literacy activities promote positive reading attitude in children learning English as a foreign language          下载免费PDF全文

Bonnie Wing‐Yin Chow  Anna Na Na Hui  Barbie Hiu‐Tung Chui 《Journal of Research in Reading》2018,41(2):278-289

This study investigated the effects of creative literacy classroom activities on the acquisition of English as a foreign language. Ninety Chinese second graders were tested on reading attitude and English receptive vocabulary knowledge. They were randomly assigned to either a control group or an experimental group, which engaged in English creative classroom activities for 10 weeks. Repeated measures analyses showed a significant interaction effect for reading attitude, providing empirical evidence that English creative classroom activities can enhance reading attitude. This study extends past research by demonstrating the links between creative activities and reading attitude, as well as highlights the feasibility of incorporating creative literacy activities within foreign language education. This provides a new direction for researchers and educators to develop instructional practices that incorporate a stimulating environment for English‐as‐a‐foreign‐language students. Future longitudinal research could examine whether these benefits can be maintained over a longer period.  相似文献   

The counseling needs of foreign students     

Ajit K. Das  Stephen Y. Chow  Bruce Rutherford 《International journal for the advancement of counseling》1986,9(2):167-174

This paper reports the findings of three studies of the counseling needs of international students at a medium sized University in the Midwestern region of USA. The studies were conducted over a period of five years (1977–83), and provide an historical perspective on the changes in student needs as well as in the programs designed to respond to these needs.  相似文献
