Exploring the Factor Structure of the RTI Readiness and Implementation Survey

Response to intervention (RtI) models have increasingly been adopted to improve outcomes for all students through the delivery of a continuum of supports and making timely responsive instructional decisions based on data. With this increasing popularity, researchers and practitioners have developed several RtI-related assessments, many of which have no known psychometric properties. As a result, there is an urgent need to develop psychometrically sound RtI readiness and implementation assessments that possess technical adequacy and practical utility. This study surveyed 377 participants to examine the factor structure of the author-developed RtI survey. An exploratory factor analysis identified seven relevant factors (system support, belief, conceptual knowledge, practical knowledge, resource, time, and system barrier) from the initial pool of 49 items. Results of reliability estimates supported the internal consistency of each subscale. Collectively, this validated RtI survey can be used to help district and school leaders efficiently screen a system's current RtI readiness and implementation status. The data may also inform successful RtI initiation and sustainment of the reform. Limitations and future directions for research are discussed.     

宫颈癌病毒病因学说的确立及其发展

德国病毒学家Harald zur Hausen博士创立的宫颈癌人乳头瘤病毒(HPV)病因学说荣获2008年度诺贝尔生理学/医学奖.笔者从辩证唯物主义认识论角度,回顾了该学说的确立及其发展.宫颈癌将有望成为人类通过疫苗接种、筛查和早诊早治等综合措施来预防乃至消除的第一个恶性肿瘤.     

脊柱侧弯手术治疗进展

随着医学技术的发展,脊柱侧弯的治疗方法也在不断的进步。针对其治疗方法的改变,提出以下思考和分析：（1）脊柱侧弯的治疗方法遵循着螺旋式上升,曲折式前进的发展过程;（2）运用适度原则和最优化原则,为患者制定个体化治疗方案;（3）运用运动发展的眼光即动态性原则来观察和解决脊柱侧弯手术治疗中存在的问题。     

台湾地区姑息医学制度的建立及法律实践

姑息治疗在提高晚期癌症患者生活质量、实施临终关怀、给予病人及其家属全面周到的照顾诸方面起着重要作用。在台湾,已为姑息治疗立法并实施了10年,积累了丰富的经验。这项法律本身及其细则、附件等配套文件使姑息治疗更加规范可行。研究规范的姑息治疗及台湾的相关法律可以帮助我们更好的理解姑息治疗的理念,帮助发展大陆同道构建有效实用的...     

高血压患者应激反应特点及行为人格的关系研究

为了解高血压患者心血管反应的特征及与健康人群的差异,使用实验和问卷调查的方法对高血压患者和健康居民进行研究。结果显示,两组在任务期和恢复期的心血管反应差异显著（P〈0．05）;病例组的健康实践行为和消极应对方式水平较高,积极应对方式有待提升;健康实践行为和恢复期舒张压呈负相关,积极应对方式和任务期收缩压呈正相关（P〈0...     

人类社会认知的神经机制:来自社会脑研究的证据

社会认知是指从环境互动的过程中推测他人意图、情感和思想等内部状态的心理加工过程。社会脑假说认为,包括人类在内的灵长类大脑内肯定存在着一个旨在认识和理解他人表情的神经机制,在社会交往中通过该中枢迅速处理与他人相互作用的各种信息。本文通过回顾社会脑的构成与基本功能,镜像神经元的发现及功能,以及社会脑、镜像神经元对社会认知影响的相关研究,提出了人类社会认知不同于其他物种的三个主要区别。     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。     

Synaptogenesis and heritable aspects of executive attention

In humans, changes in brain structure and function can be measured non-invasively during postnatal development. In animals, advanced optical imaging measures can track the formation of synapses during learning and behavior. With the recent progress in these technologies, it is appropriate to begin to assess how the physiological processes of synapse, circuit, and neural network formation relate to the process of cognitive development. Of particular interest is the development of executive function, which develops more gradually in humans. One approach that has shown promise is molecular genetics. The completion of the human genome project and the human genome diversity project make it straightforward to ask whether variation in a particular gene correlates with variation in behavior, brain structure, brain activity, or all of the above. Strategies that unify the wealth of biochemical knowledge pertaining to synapse formation with the functional measures of brain structure and activity may lead to new insights in developmental cognitive psychology.

西安市小学生中独生与非独生子女个性品质的比较研究

本文研究了西安城区１０所小学７８７名独生与非独生子女个性品质方面的情况。我们设计了有１８个行为项目的教师问卷（每项按五等评分）及家长问卷;对结果进行了因素分析,据所聚类的项目内容,将所得四个因素命名为人际关系、自我中心、学习动力和独立性,进行多变量的变异数分析结果表明,独生子女的自我中心和学习动力比非独生子女强烈;而独立性却比非独生子女差．这说明独生子女在个性品质方面既有缺点,也有优点,不能说得一无是处;关键在于正确的教育思想和方法。
