亲子沟通的三层次模型:理论、工具及在小学生中的应用

目前的亲子沟通研究存在测量工具缺乏理论依据、测量层次和内容混乱等问题.本研究在系统论思想的指导下提出亲子沟通的三层次模型,从元素、关系和系统三个层面考察亲子沟通状况,并以此模型为基础编制了相应测量工具.经过文献梳理、理论建构、工具编制等环节,逐步完善了模型和相应测量工具.以371名小学五、六年级儿童为被试,检验了亲子沟通量表的可靠性和有效性,并考察亲子沟通基本状况.结果表明,(1)亲子沟通量表的信、效度指标达到了心理测量学要求,能够用于相关实证研究中;(2)被试家庭中,父母的沟通能力优于儿童,母子沟通质量优于父子沟通,母亲的沟通地位比父亲高;(3)父母的倾听能力能有效预测亲子沟通质量,提高父子沟通质量是让父子和母子两种沟通更协调的主要途径.     

语言伴随性手势是否和语言共享同一交流系统?

语言伴随性手势是人类语言交流的一个普遍的特征, 它可以发挥信息交流的功能。依据产生目的以及适用范围的不同, 手势可以分成表象性手势和非表象性手势。多数研究者认为, 语言和手势动作是“近亲”, 具有“家族相似性”。来自语言发展、认知心理学和认知神经科学的证据均表明, 手势和语言共享同一个交流系统。当手势动作和发音单词意义相同时, 手势动作受到单词发音的干扰, 同时引发发音共振峰2 (F2)的放大。手势和言语之间遵循互相作用理论, 它们作用的基础是语义一致性, 镜像神经系统完成了两者语义一致性的传递。由于语言伴随性手势和语言之间的关系是语言和行为结合良好的特例, 因此, 对语言伴随性手势的研究将有助于对人类心智有一个更深层次的认识和理解。     

连续性肾脏替代治疗临床应用的拓展与思考

连续性肾脏替代治疗（continuous renal replacement therapy, CRRT）是近30年来在透析技术基础上蓬勃发展起来的一种新的血液净化技术。CRRT最早应用于重症急性肾衰竭（acute renal failure,ARF）的治疗,随着人类对CRRT认识的不断深化和技术的不断发展,CRRT的...

The life and times of PSI

This paper describes the essential features of the personalized system of instruction (PSI). Results from outcome research examining the effectiveness of PSI-based courses relative to traditional methods provide unequivocal support for the superiority of PSI. Parametric studies, or component analyses, show that the mastery requirement, immediate performance feedback, and review units are the key features underlying high quality student performances in PSI courses. The use of student proctors as peer-tutors, optional lectures, and selfpacing do not, in and of themselves, appear to be vital to student success in PSI courses. Despite its superiority, PSI has not supplanted traditional methods as the dominant pedagogical system in higher education. Difficulties inherent in overcoming the inertia of the lecture within our established instructional system, the implications of PSI for that system, and the Zeitgeist that permeates educational reform are the major obstacles to widespread adoption of PSI.     

Determination of a behavioral transfer function: White-noise analysis of session-to-session response-ratio dynamics on concurrent VI VI schedules

Six pigeons were exposed to concurrent variable-interval schedules in which the programmed reinforcer ratios changed from session to session according to a pseudorandom binary sequence. This procedure corresponded to the stochastic identification paradigm (“white-noise experiment”) of systems theory and enabled the relation between log response ratios in the current session and log reinforcer ratios in all previous sessions to be determined. Such dynamic relations are called linear transfer functions. Both nonparametric and parametric representations of these, in the form of “impulse-response functions,” were determined for each bird. The session-to-session response ratios resulting from the session-to-session pseudorandom binary variations in reinforcer ratios were well predicted by the impulse-response functions identified for each pigeon. The impulse-response functions were well fitted by a second-order dynamic model involving only two parameters: a time constant and a gain. The mean time constant was 0.67 sessions, implying that the effects of abrupt changes in log reinforcer ratios should be 96% complete within about five sessions. The mean gain was 0.53, which was surprisingly low inasmuch as it should equal the sensitivity to reinforcement ratio observed under steady-state conditions. The same six pigeons were subjected to a similar experiment 10 months following the first. Despite individual differences in impulse-response functions between birds within each experiment, the impulse-response functions determined from the two experiments were essentially the same.     

综合性大学开设长学制高等医学教育的初步研究

我国现有的医学教育学制偏短,不利于培养高质量医学人才。综合性大学有着许多办学优势,有利于开设长学制医学教育,因此,要发挥综合性大学的优势,实行多通道办学模式,学分制和弹性学制,强化公共基础教育和人文素质教育,改善办学条件,提高管理水平,努力培养能参与国际竞争的高层次医学人才。     

Pluralism and values in education in Hungary – changes between 1990 and 2012

Value transmission is a fundamental task of schools. However, the question arises as to how far prevailing political and social conditions shape the functioning of a country or a region’s school system. In other words: what effect do they have on the choice of values to be transmitted at schools? Are there any fundamental social values that are shared by different cultures at different times? Are there values that exist independently of social and political systems? These questions have a special relevance in Eastern and Central European countries like Hungary where political and social changes in the twentieth century had a crucial effect on the set of values that were transmitted by the school system. The aim of this study is to describe how the value transmitting role of the Hungarian school system has changed as a consequence of political transformations in recent decades.
