Maternal Attitudes and Knowledge of Child-Rearing: Associations with Family and Child Outcomes   总被引：1，自引：0，他引：1  

April Ann Benasich  Jeanne Brooks-Gunn 《Child development》1996,67(3):1186-1205

A prospective, longitudinal study of a low birthweight, preterm cohort examined the effects of maternal knowledge of child development and concepts of child rearing on the quality of home environment and on child cognitive and behavioral outcomes. Measures of maternal knowledge at 12 months were found to be significantly associated with the quality of the home environment, the number of child behavior problems, and to a small but significant extent child Stanford-Binet IQ at 36 months. Maternal characteristics were associated with both maternal knowledge and maternal behavior. Child characteristics, including birthweight, were not associated with maternal knowledge or concepts of development for most of the cohort. Subgroup analyses by race/ethnicity revealed a similar pattern of results. However, a measure of neonatal health status was shown to be significantly associated with cognitive outcome in the African-American subgroup at 24 and 36 months.  相似文献   

A pilot evaluation of the social validity of a bullying bystander program adapted for high school students     

Diana M. Doumas  Aida Midgett  April D. Watts 《Psychology in the schools》2019,56(7):1101-1116

Although school‐based programs are effective at decreasing bullying, the majority of studies have been conducted with elementary and middle school students. We conducted a pilot study using a randomized controlled design investigating the social validity of a brief, bullying bystander program adapted to be age‐appropriate for high school students (N = 65). Results indicated that high school students in the intervention group perceived the program to be acceptable and relevant and reported greater increases in knowledge ( = 0.27) and confidence to intervene ( = 0.27) in bullying situations compared to students in the control group. Despite being trained in the use of four intervention strategies, students reported using two of the strategies infrequently. Additionally, we found a significant difference between the intervention and control group for only one strategy (Φ = ?0.44). This study provides partial support for the social validity of the adapted program. Implications for implementing the program at the high school level are discussed.  相似文献   

Understanding Asian American women's pathways to school leadership     

Jia G. Liang  James Sottile  April L. Peters 《Gender and education》2018,30(5):623-641

Little is known about Asian American women administrators in the public schools. The study sought to understand the pathways of Asian American women to school leadership. In-depth interviews and researcher reflective memos were the primary data sources. The participants included 15 Asian American female school administrators in two states. We found that the women's career trajectories were similar yet unique; they were manifestation of the women's intersected experiences of gender, race–ethnicity, and age, situated in particular time and place. Often than not, the women had to negotiate their leadership aspiration and advancement through raced and gendered expectations. Others' encouragement and mentoring were instrumental for the women's development of self-knowledge and demystification of the leadership process. Most women taught at least 10–15 years before entering leadership. The women of earlier generations had far less career mobility and slim, if not absent, mentoring opportunities.  相似文献   

Damage assessment of a continuous beam bridge based on the strain mode     

杜思义 《重庆大学学报(英文版)》2003,2(2)

1. Introduction In the structural damage identification, the confirmation of parameters sensitive to damage is the foremost, namely to decide what parameters are to be adopted, the next is to distinguish damaged from undamaged, and to determine the position and severity of damages. For local damage, an identifying parameter should be a local quantity and accord the following 4 basic conditions: 1) it is sensitive to local damages and is a monotone function depicting the severity of structural …  相似文献   

怪盗Kid历险记     

April 《广东第二课堂》2006,(20)

怪盗Kid趁着海军大臣外出的时候,潜入他的家里,四处寻找他和A国间谍私通的密函和他要卖给A国的国家机密。终于,他在一幅画的后面找到了保险箱,并顺利的破解了密码,把密件拿到手。这时候,门外传来海军大臣的声音,他回来了。Kid唯一可以逃跑的机会就是跳进窗外的小河。可是跳进小河就会把密函弄湿。窗外正对着一栋废弃的建筑物的一个窗口,他的助手就在那里接应。他尝试把密函递给助手,却发现两人无论怎样伸长手臂还是相差70厘米。把密函扔过去吧,但是窗外的风很大,很容易把密函吹走的,并且他怕丢不准。海军大臣已经在转动钥匙了,时间紧迫,究竟要怎样做才能把密函安全地送走呢?忽然,他灵机一动,想出了一个绝妙的法子。他送出密函后,在海军大臣进来之前跳进小河顺利逃走了。怪盗Kid究竟想出了什么绝妙的法子呢?答案:怪盗Kid和他的助手都各自脱掉袜子,伸出腿来传递密函。因为人的腿要比手长,70厘米的距离就那样消除了。这条小河是通向大海的,怪盗Kid登上停靠在海边的一艘小艇,出海了。他在海军大臣的家里留下了挑战书,大臣一定不会放过他的。海上的天气很恶劣,刮起了飓风,他流落到一个荒芜的小岛上。怪盗Kid被岛上的土著人俘虏了。土著首领有意刁难这个陌...  相似文献

Jumping Into the Deep End: Developing Culturally Responsive Urban Teachers Through Community-Immersive Partnerships     

April L. Mustian  Robert E. Lee  Carlos Nelson  Valentina Gamboa-Turner  Lisa Roule 《The Educational forum》2017,81(4):467-481

Abstract

Preparing special educators for the highest-need schools remains an ongoing challenge in urban districts across the United States. One university’s collaborative community-based immersive partnership model, with emphasis on service learning, has demonstrated promising levels of impact on candidates’ preparation as preservice teachers learning how to celebrate the rich cultural histories of the communities where they are immersed. Both quantitative and qualitative results on the impact of one specific example of this work are provided.  相似文献   

Anti-periodic traveling wave solution to a forced two-dimensional generalized KdV-Burgers equation

1. Introducton The two-dimensional KdV equation was first derived by Kadomtsev and Petviashvili in 1970 [1], and it is also referred to as the KP equation. Periodic Traveling wave solutions to the KP and modified KP equation were investigated by Chen and Wen [2]. The author considers the generalized inhomogeneous two-dimensional KdV-Burgers equation as follows. {}[()] 0,,,0,txxxxxxxyyufuuuugxytabd+++++=纬% (1.1) where f C2(); b, d and a are given constant…  相似文献   

Field emission from Si tips coated with nanocrystalline diamond films   总被引：1，自引：0，他引：1

1. Introduction Recently, carbon nanotubes have attracted a lot of interest because of their outstanding electrical properties and their potential application as a possible material for fabrication of cold cathodes [1-3]. It was found that the field enhancement from carbon nano-tubes exhibited large local field enhancement and considerable field emission currents at relatively low applied voltage. Carbon nanotube-based field emission displays have been fabricated using well-aligned nano-tubes …  相似文献
