应当建立科学的医疗纠纷技术鉴定体制

现行的医疗纠纷技术鉴定模式年来在解决医疗纠纷中起到了重要作用,但随着卫生改革的进一步深化和法制的日趋健全,以及人们法律意识的不断提高它的缺陷也日益突出。应当建立新的医疗技术鉴定管理体制,鉴定委员会的人员鸺成,增强医疗技术透明度,建立时效制度和回避制度。     

Spontaneous performance of wild baboons on three novel food-access puzzles

Although the technical problem-solving expertise of nonhuman primates has been investigated extensively in captivity, few species have been tested in their natural habitats. Here I examine the physical cognition of wild savanna baboons (Papio anubis), a species that occupies an omnivorous foraging niche in which a variety of embedded food items are extracted and processed. Baboons were tested on three puzzles, each involving high-quality food that required removal from a novel obstruction: (1) a string-pulling puzzle in which food was hung from tree branches, (2) a twig-dipping puzzle in which food was embedded in a vertical tube, and (3) a stick-pushing puzzle in which food was contained in a horizontal conduit. The baboons failed to solve the second and third puzzles even when tools had been appropriately positioned in advance. And although they solved the first puzzle, their actions (running while holding food that was still attached to the string), suggested they did not fully comprehend the string’s connective property. The baboons’ performance might reflect the time constraints of life in the wild, which relative to captivity may provide fewer opportunities for the development of understanding about the physical properties of objects and their potential uses as tools. Further experiments on the physical cognition of baboons and many other primate species in their natural habitats would help test this ontogenetic hypothesis. Such field experiments would be especially fruitful if they continued to target extractive foragers like baboons: these experiments could simultaneously provide a test of phylogenetic hypotheses that invoke extractive foraging as the key stimulus for brain expansion in savanna-dwelling hominids.

两宋史事易学的演变与发展特征

援史释《易》成为宋儒解《易》的常用方式,虽然此种注《易》方式并不始于宋代,但大量用史在宋代易学阐释中表现的尤为突出。究其原因,当与宋代儒学复兴、史学发展以及宋代士人的政治观念有着密切的联系。北宋与南宋的史事易学又呈现出明显的不同,北宋援引史事是出于解说义理的需要,而南宋则用史事解证卦爻辞,直接将《周易》视为一部极具历史借鉴及指导意义的经典。南宋卦卦有史的《周易》阐释并不是一朝一夕形成的,而是北宋援引史事以证易理的继承与发展。     

《周易》家人卦的家道要旨

《周易》家人卦的家道理论体系,由立家之道、安家之道和兴家之道构成,且三位一体而又层层递进。立家之道,源于“阴阳变易”之化生原理,宏于“阴顺阳威”;付之践行,始于“闲邪未蒙”,功在“厉威勿纵”,誉于“顺德利贞”。安家之道,据于“允执厥中”的象位原理,适于“中正合宜”;履之于家,固于“持守正道”,毅于“谨遵中德”,成于各安角色。兴家之道,基于“民安国泰”的系统法则,旨在“家齐国治”;行之于家,寓于“王假有家”,系于交感互爱,遵于唯变所适。整个家道理论体系是一个系统有机统一的整体,极具系统性与辩证性。     

Evoked potential and visual half-field evidence for task-dependent cerebral asymmetries in congenitally deaf adults

Evoked potentials to laterally presented stimuli were collected from left and right tempero-parietal sites during performance of two visual half-field tasks, lexical decision, and line orientation discrimination. Reaction time and accuracy data were simultaneously collected. The behavioral data indicated the development of a right field advantage for the lexical decision task as a function of practice. A principal components analysis revealed three independent evoked potential components which displayed task-dependent hemispheric asymmetries. Multiple regression analyses revealed that visual half-field asymmetries in response accuracy were closely related to hemispheric asymmetries on several independent evoked response components. Subject's scores on independent tests of verbal reasoning and spatial relations were also found to be closely related to hemispheric asymmetry on several independent evoked response components. These data support a multidimensional concept of cerebral specialization. They also suggest that visual field asymmetries reflect the confluence of several underlying processes which have independent lateralization distributions across the population. In general, the results underscore the need for further research on the nature of the relationship between cerebral and perceptual asymmetries.     

From Searle’s Chinese room to the mathematics classroom: technical and cognitive mathematics

Employing Searle’s views, I begin by arguing that students of Mathematics behave similarly to machines that manage symbols using a set of rules. I then consider two types of Mathematics, which I call Cognitive Mathematics and Technical Mathematics respectively. The former type relates to concepts and meanings, logic and sense, whilst the latter relates to algorithms, heuristics, rules and application of various techniques. I claim that an upgrade in the school teaching of Cognitive Mathematics is necessary. The aim is to change the current mentality of the stakeholders so as to compensate for the undue value presently attached to Technical Mathematics, due to advances in technology and its applications, and thus render the two sides of Mathematics equal. Furthermore, I suggest a reorganization/systematization of School Mathematics into a cognitive network to facilitate students’ understanding of the subject. The final goal is the transition from mechanical execution of rules to better understanding and in-depth knowledge of Mathematics.

Returning to experience – Dewey’s second mission to China

ABSTRACT

In this essay, as a philosophical exercise in exploring some of the underlying assumptions that serve as an interpretive context for classical Chinese philosophy, I will first follow Dewey’s philosophical turn from a ‘knowledge paradigm’ to an ‘experience paradigm’ in which he seeks to overcome the dualism between subject and object. Secondly, I will interpret Dewey’s Darwinian challenge to the notions of Aristotelian ‘species’ (eidos) and ‘teleology’ (telos) and their ‘universality.’ In so doing, Dewey sought to restore time, change, relationality, and particularity to our philosophical agenda, ideas that are all recommended by the cosmology of the first among the Chinese philosophical canons, the Book of Changes (Yijing易经). And finally, I will try to offer an interpretation of traditional Chinese philosophy as a science in a Deweyan sense.
