青春期开始时间早晚对初中女生自我概念的影响

目的:探讨青春期开始时间早晚对初中女生自我概念发展的影响。方法:整群抽取初一至初三年龄12-14岁的女生共658人,采用青春期发育量表、田纳西自我概念量表进行测量。结果:①绝大多数12至14岁的女生青春期发育状态处于青春期中和青春期晚期（二者合占90%）;②年龄×青春期发育水平的方差分析显示,在自我概念各因子分及总分上,年龄和青春期发育水平的主效应均不显著;③在家庭自我、社会自我、自我认同、自我行动以及自我概念总分上年龄与青春期发育水平交互效应显著,高年龄低青春期发展水平和低年龄高青春期发展水平的初中女生的得分均较低。结论:青春期开始时间早晚可能对初中女生的自我概念的发展有一定影响,青春期开始时间晚或早均不利于女生自我概念的发展。

Transfer of hue matching in pigeons.

Pigeons were trained on a modified three-key matching-to-sample procedure, in which only one comparison key (rather than two) was lighted after an observing response to the center-key standard. Pecks on keys of matching comparison hues were reinforced. When non-matching hues appeared as the initially lighted comparisons, the nonmatching hue terminated and the matching hue appeared on the other side key only if the pigeon did not peck the nonmatching comparison for 4.8 sec. Pecks to the nonmatching hue reset the 4.8-sec delay interval. Three hues were used during acquisition. During transfer tests, two novel hues were substituted individually or together for one or two of the training hues. Latencies to the novel side-key hue were shortest when a novel matching hue appeared as the standard on the center key, and were essentially identical to baseline matching latencies. In contrast, when a novel hue appeared as either a standard or comparison in a nonmatching combination, latencies increased with increasing separation between the noevel hue and the nonmatching hue. These transfer data demonstrate the concept of hue matching.     

The topics in medieval logic

The topics is a theory of argumentation based upon topoi or in Latin loci. The medieval logicians used works by Aristotle and Boethius as their sources for this doctrine, but they developed it in a rather original way. The topics became a higher-level analysis of arguments which are non-valid from a purely formal point of view, but where it is none the less legitimate to infer the conclusion from the premiss(es). In this connection the topics give rise to a number of discussions about the form and the matter of arguments. Further the topic contribute to the elaboration of the important doctrine of the second intentions, i.e. higher-level concepts of the particular things. In some respects the topics may be said to form a link between formal and informal logic. The topics vanished as a part of logic at the end of the Middle Ages, perhaps because the medieval logicians never got rid of Boethius' claim to have compiled a complete list of the loci, which was an unlucky one. The topics does not have an exact parallel in modern formal logic, but some reflections on non-formal argumentation by recent authors contain certain resemblances to it.     

Stimulus control of the pigeon's ability to peck a moving target.

Two pigeons were trained to peck whichever of eight keys displayed a white field (SD). The other seven keys displayed a white "X" on a black background (S delta). Each peck to SD produced three-second access to grain, a three-second intertrial interval (ITI), and the next trial. Pecks to S delta produced a three-second timeout (TO) and the same trial. During later sessions the key displaying SD changed every t seconds (t = 3, 2, 1, .5, and .25 sec), requiring the birds to track the position of the SD. Pecks on a ninth key increased t. Several sessions employed novel stimuli to ascertain the controlling stimulus dimensions. Both birds made few errors acquiring the original discrimination. During the tracking sessions, both birds made few errors when t = .5 sec. Only one reliably lengthened t. Data from sessions with novel stimuli indicate that color and form were important aspects of SD and S delta respectively; movement contributed to the final performance.     

药品带量采购的阻力、压力与垄断力问题探讨

带量采购是深化三医联动改革的重要尝试,药品集采作为医保改革的抓手试图撬动医疗及医药领域改革,为持续推进医疗卫生制度改革走向深入带来一线曙光。带量采购政策本质上涉及不同利益的再分配,藉由政府宏观调控及微观规制手段,最终实现药价降低、群众普惠的效果。基于对带量采购的理论分析及目前试点过程中存在的阻力、压力与垄断力问题,提出平衡理念为带量采购助推三医联动改革走向深远提供了一种思路。

     

4～5岁儿童对书面数符号的表征和理解能力的发展

本研究对61名中班儿童的书面数符号表征和理解能力进行了跟踪调查。一年中三次个别面试的结果表明,约40％的4岁儿童已能运用1—10的书面数符号表征数量。至中班末期,大多数5岁儿童能够较熟练地运用至少1一17的书面数符号来表征数量,尽管其中有人在两位数的表征和数字的正确写法上有困难。儿童的书面数符号表征与他们的基数概念发展水平密切相关。大学附属幼儿园4—5岁儿童的书面数符号表征能力好于为工人家庭服务的幼儿园儿童的能力。     

论马克思的实践——社会生产关系本体论

For a long time, under the influence of traditional Western philosophy, Orthodox interpreters have distorted Marx’s philosophy as the ontology of matter, thereby concealing the essence of Marx’s philosophy, and eliminating the fundamental difference between Marx’s philosophy and traditional philosophy. This paper proposes that Marx’s philosophy is not the ontology of matter, but on the contrary, by examining the ontology of matter, Marx put forward his own ontological theory, i.e., the ontology of the praxis-relations of social production, by which Marx linked the realms of phenomenon and essence, revealing the content and essence of his philosophy. __________ Translated by Kong Hui from Zhexue yanjiu 哲学研究 (Philosophical Researches), 2008, (3): 3–11     

Towards a structural concept of agonism

The model presented attempts to describe the agonistic situation from the point of view of the individual, taking psychological, ecological, and ethological factors that can influence behavioral expression into account. The animal is considered as consisting of an “ego” and “soma,” these being conceptualized as concentric circles surrounding the gene carrier itself. The hierarchy of responses present to protect the gene carrier together with their motivatory causal factors and their energy expenditures are described and agonism considered as a means by which optimal inclusive fitness can be attained.
