生物自组织临界性与肿瘤

分析了局部组织由再生、化生和癌变呈现的各种宏观行为和性质,从生物自组织临界性的角度讨论了这类行为和性质的演化模式及机制,指出肿瘤实质是局部组织经历一系列临界状态下相变造成的。     

Analyse des prélèvements biologiques médico-légaux : quel cadre juridique à l’ère de la qualité?

Medico-legal autopsy sometimes requires the use of the Parasitology-Mycology specialty. Two recent medico-legal clinical cases, involving this specialty, have questioned us. First of all, may a non-conformity biological analytical (compared to accepted and accredited standards by COFRAC) fail the whole biological expertise, and thereafter, the medico-legal expertise of the file? The answer must consider that the raw result obtained as a result of a medical biology technique must be interpreted and discussed by the expert in the discipline (in this case by the parasitologist) before being included in the medical discussion and discussed by the medical examiner. The judgment is secondarily delivered by the judge according to his intimate conviction and without determining the probative value of the examination. Should a post-mortem biological examination be part of an expertise in medical biology or is it a technical and scientific examination? This answer is based on the previous one, considering the significant contribution of the expert who will bring his knowledge, interpreting and discussing the raw result. A simple technical and scientific examination would only provide the raw result without any assessment of the context and circumstances of the biological sample.     

Do children think that inheritance determines height and weight?

Three studies were conducted to investigate if children think that physical growth is determined by inheritance. All three studies employed the “switched‐at‐birth” task. Study 1 investigated if children and adults thought that height and weight were determined by parentage. Study 2 examined preschoolers and elementary school children's and adults' understanding of the role of parentage and nutrition in determining weight. Study 2a examined children's and adults' understanding of the role of parentage and nutrition in determining height. Results indicate that overall, preschoolers and third graders have more of an inheritance bias for height than for weight. However, when nutrition was introduced, apart from third graders, all other grades reasoned that nutrition played a greater role in determining weight. Overall, these results indicate that even young children have a rudimentary but differentiated theory of the role of inheritance in determining height and weight.

Highlights

• Participants were presented with switched‐at‐birth tasks to determine if they thought that parentage and/or nutrition influences height and weight.
• Young children viewed height as determined more by parentage than weight, suggesting that they have a differentiated and autonomous theory for the determination of height.

     

学前儿童用“人为不介入原理”区分生物、非生物能力的发展

本研究采用访谈法,考查4～6岁儿童对生物的“人为不介入原理”的理解。研究结果表明：1．学前儿童没有表现出明显的“泛灵论”倾向。2．学前儿童对“人为不介入原理”的理解随年龄增长而呈现提高趋势,多数6岁儿童已经能够利用这一原理区分生物和非生物。3．学前儿童对不同领域刺激物的认知表现出不平衡性,对动物的认知优先发展,植物次之,对人造物认知的发展落后于对生物认知的发展。4．学前儿童表现出初步的分类概念。

睡眠拖延行为背后的心理生理机制解析

摘 要 睡眠拖延行为是健康行为拖延领域提出的一个新概念,其可概括为在没有外部原因阻碍的情况下,仍无法在预定时间上床睡觉的现象。目前的研究认为睡眠拖延行为是导致普通人群睡眠不足的重要原因,睡前日常活动及沉浸式活动常常诱导其发生,探讨其背后机制主要涉及自我调节和生物节律两大因素。利用时限性自我调节理论可尝试解析睡眠拖延行为的发生过程。未来研究可从其神经机制探讨及预防和干预措施等方面尝试展开。     

Postfoundationalism and Interdisciplinarity: A Response to Jerome Stone

Abstract. In my recent work I argued that the religion and sciencedialogue is most successful when done locally and contextually. However, I also argued against theology's epistemic isolation in a pluralist, postmodern world, and for a postfoundationalist notion of human rationality that reveals the interdisciplinary, public nature of all theological reflection. I now want to explore the possibility that, when we look at what the prehistory of thehuman mind reveals about the biological roots of all human rationality, some forms of contemporary evolutionary epistemology may actually hold the key to understanding the kind of cognitive fluidity that enables true interdisciplinary reflection. Philosophically the religion and science dialogue benefits from this move when a postfoundationalist notion of rationality redescribes the dynamic interaction of our various disciplinary dialogues with one another as aform of transversal reasoning. Transversality in this sense justifies and urges an acknowledgment of multiple patterns of interpretation as one moves across the borders and boundaries of different disciplines.     

5岁儿童对生物特征的限制性推理的实验研究

本研究用推理法范式研究5岁儿童在不同条件下,对生长、生病、进食、呼吸和排泄等生物特征的限制于生物类别的限制性推理.结果表明,以人为例引入特征及对特征给予生机论的解释,都能提高儿童的限制性类别推理.儿童对生物特征的认识中,存在拟人化的推理模式和生机论的因果关系解释系统.儿童对动物和植物的认识发展是不均衡的,对动物的认识优先发展;对动植物共有的特征已有所认识,但对各个特征的认识发展是不均衡的.
