The study examined how child and parent characteristics, and contextual sources of stress, such as marital conflict predict initial status and trajectories of parent involvement, support, and harsh control, over a 4‐year period in families in Taiwan (= 4,754). Based on Belsky's (1984) ecological model of parenting, three domains predicting parenting were tested, child characteristics (age cohort and gender), father and mother characteristics (education and depressive symptoms), and contextual sources of stress (marital conflict). The study followed two cohorts of children; the younger cohort was followed from first to fourth grade and the older cohort from fourth to seventh grade. Initially, fourth graders reported more parental involvement, support, and harsh control than first graders. However, involvement, support, and harsh control decreased across the 4 years for the older cohort as they transitioned to early adolescence. In the first year, girls reported more parental involvement and support and less harsh control than boys. Across the 4 years, involvement and support increased, and harsh control decreased for boys; whereas involvement stayed the same, support slightly decreased, and harsh control slightly increased for girls. Children whose parents were more educated reported more parent involvement, support, and harsh control in the first year. Children whose fathers were chronically depressed and whose parents were experiencing marital conflict reported decreasing parent involvement and support over the years.  相似文献

Generalized DINA Model(G-DINA)为认知诊断模型提供了一个一般性的理论框架,而高阶诊断模型不仅能描述被试的总体水平,还能描述被试对属性的掌握情况(微观的认知状态)以及被试掌握属性与能力的关系,提供更丰富的信息。如果能把这两者结合起来,可能对实际诊断工作的操作有较大帮助。文章首先对考虑高阶结构的整合性模型——HO-GDINA模型的形式进行讨论,探讨其参数估计EM算法的实现,并用模拟过程对模型的估计精度进行研究,结果验证了HO-GDINA的EM算法的正确性,并且说明该算法对该模型有较高估计精确度。然后用饱和模型在约束条件下的特殊形式HO-DINA模型对"分数减法"这一经典数据进行EM算法参数估计和具体分析,展示了HO-GDINA在实际情况中的具体使用,并与de la Torre之前用MCMC估计算法得到的研究结果做比较,基本一致,进一步表明HO-GDINA模型的参数估计EM算法在实际情境中的特殊形式下仍然适用。  相似文献

Since the last decades of the 20th century,analytic philosophy has been undermined by many philosophers in many ways.Some have claimed that analytic philosophy effectively ended with Quine's attack on empiricist dogmas,moving in an alternative direction.Others have insisted that it endures,taking a specific approach to philosophical problems inspired by prior speculation.Still others have criticized it based on recent developments in such fields as neuroscience and computer science.Clearly,the present status and the nature of analytic philosophy has been disputed.Several international conferences have recently been held in China to reflect upon,and respond to,these controversies.  相似文献

This study compared how adults assess the credibility of children who either: (1) experienced a misleading suggestive interview, (2) were coached to lie or (3) experienced a non‐misleading interview. Preschool children (N = 24) were interviewed about a game they had played. One third of them spontaneously reported the truth, one third lied in response to coaching and one third spontaneously reported misinformation from a prior misleading suggestive interview. One hundred and twenty‐nine college students watched videotaped interviews of these children describing their alleged play activities and assessed their credibility. Children who had experienced misleading suggestive questioning were rated as less credible than those who were telling the truth and those who were lying. Adults could accurately detect truth‐telling children above chance, whereas accuracy was below chance detecting both lying children and children who had been misinformed. Adults were most confident of their ratings of truth‐telling children. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

联绵词由两个音节连缀成义,以音表义,所以从字形上往往不能得到准确的意义信息.《晋》卦中“鼫鼠”是联绵词,表示迟疑不决之貌.通过转语系联,发现“鼫鼠”与“首鼠”、“犹豫”、“蹢躅”等是同一个词的不同书写形式.然后,比较《晋》卦中的类同句,回归语境,证明“鼫鼠”训作“迟疑不决之貌”是合理的.  相似文献

We apply Quinn and Rohrbaugh's (1983) competing values framework (CVF) as an organizing taxonomy to meta-analytically test hypotheses about the relationship between 3 culture types and 3 major indices of organizational effectiveness (employee attitudes, operational performance [i.e., innovation and product and service quality], and financial performance). The paper also tests theoretical suppositions undergirding the CVF by investigating the framework's nomological validity and proposed internal structure (i.e., interrelationships among culture types). Results based on data from 84 empirical studies with 94 independent samples indicate that clan, adhocracy, and market cultures are differentially and positively associated with the effectiveness criteria, though not always as hypothesized. The findings provide mixed support for the CVF's nomological validity and fail to support aspects of the CVF's proposed internal structure. We propose an alternative theoretical approach to the CVF and delineate directions for future research.  相似文献
