耳畸形及缺损修复发展的历史回顾

耳整形是耳鼻喉手术中最具挑战的技术之一。本文从耳廓畸形及缺损修复材料,修复技术两方面综述了耳整形修复的发展。其中快速原形及组织工程技术应用于耳廓畸形及缺损修复是机械学、材料学与生物医学相互交叉互相渗透,共同发展的结果。这两种技术为耳廓修复整形提供了光明的前景,也是目前此领域科学研究的热点。但是新的理论和技术应用于临床还需要经历缓慢的实践与发展过程。

Are Newborns Morally Different from Older Children?

Policies and position statements regarding decision-making for extremely premature babies exist in many countries and are often directive, focusing on parental choice and expected outcomes. These recommendations often state survival and handicap as reasons for optional intervention. The fact that such outcome statistics would not justify such approaches in other populations suggests that some other powerful factors are at work. The value of neonatal intensive care has been scrutinized far more than intensive care for older patients and suggests that neonatal care is held to a higher standard of justification. The relative value placed on the life of newborns, in particular the preterm, is less than expected by any objective medical data or any prevailing moral frameworks about the value of individual lives. Why do we feel less obligated to treat the premature baby? Do we put newborns in a special and lesser moral category? We explore this question from a legal and ethical perspective and offer several hypotheses pertaining to personhood, reproductive choices, “precious children,” and probable evolutionary and anthropological factors.     

Recognizing the infant as subject in infant-parent psychotherapy

Drawing on Winnicott's view of infants as subjects entitled to an intervention in their own right, infants as the referred patient have been seen in infant-parent psychotherapy for 20 years at the Royal Children's Hospital, Melbourne, Australia. This is a radically different view of infant symptomatology than viewing it as only expressing an aspect of the mother's unconscious. The clinical pathway differentiates the therapy from much parent-infant psychotherapy. The author describes the theoretical model of a twofold approach to understanding the infant's experience through interactive dialogue between therapist and infant, and sharing this understanding with the parents, and illustrates it with cases of failure-to-thrive infants. She discusses two criticisms: first, that infant-parent psychotherapy may undermine the parents and, second, that brief parent-infant psychotherapy does not alter parents' insecure attachment status. Videotaped sessions often show rapid improvement; parents generally feel relieved. This approach potentially shapes not only parents' and infants' representations, but also their implicit knowledge of relationships-partly, it is suggested, through activating the mirror neuron system to bring about implicit memory change. Change may therefore be longer lasting than psychoanalytic theory presently conceives. The approach is relevant in an outpatient setting: gains were maintained long term in 90% of out-patient cases.     

Kinematic and ground reaction force accommodation during weighted walking

Weighted walking is a functional activity common in daily life and can influence risks for musculoskeletal loading, injury and falling. Much information exists about weighted walking during military, occupational and recreational tasks, but less is known about strategies used to accommodate to weight carriage typical in daily life. The purposes of the study were to examine the effects of weight carriage on kinematics and peak ground reaction force (GRF) during walking, and explore relationships between these variables. Twenty subjects walked on a treadmill while carrying 0, 44.5 and 89 N weights in front of the body. Peak GRF, sagittal plane joint/segment angular kinematics, stride length and center of mass (COM) vertical displacement were measured. Changes in peak GRF and displacement variables between weight conditions represented accommodation. Effects of weight carriage were tested using analysis of variance. Relationships between peak GRF and kinematic accommodation variables were examined using correlation and regression. Subjects were classified into sub-groups based on peak GRF responses and the correlation analysis was repeated. Weight carriage increased peak GRF by an amount greater than the weight carried, decreased stride length, increased vertical COM displacement, and resulted in a more extended and upright posture, with less hip and trunk displacement during weight acceptance. A GRF increase was associated with decreases in hip extension (|r| = .53, p = .020) and thigh anterior rotation (|r| = .57, p = .009) displacements, and an increase in foot anterior rotation displacement (|r| = .58, p = .008). Sub-group analysis revealed that greater GRF increases were associated with changes at multiple sites, while lesser GRF increases were associated with changes in foot and trunk displacement. Weight carriage affected walking kinematics and revealed different accommodation strategies that could have implications for loading and stability.     

贝叶斯推理的三重加工心智模型

自二十世纪60年代Edwards首次用实验研究人类推理是否遵循贝叶斯规则以来,国内外贝叶斯推理研究取得了长足的发展,但也出现了一些困境:对影响贝叶斯推理的客体因素和主体因素研究未成体系,解释理论莫衷一是。未来的研究应该重新审视客体与主体的关系,系统整合和多角度分析影响贝叶斯推理的因素,尝试以三重加工心智模型解释人类贝叶斯推理行为,并对以往的解释理论进行融合,从而更好地揭示人类不确定性决策的本质。     

Are animals moral?: Zhu Xi and Jeong Yakyong’s views on nonhuman animals

One significant feature of Jeong Yakyong’s丁若鏞 (1762–1836) thought is his deconstruction of Zhu Xi’s 朱熹 (1130–1200) moral universe based on li 理 and qi 氣. For Zhu Xi, the world in its entirety was a moral place, but Jeong Yakyong distinguished nonmoral domains from the moral domain. One question that follows in pursuing a comparison of their philosophies on this topic is what each thinker meant by ‘moral’ and, in particular, whether they meant the same thing. In this paper, I delve deeper into this topic by comparing their respective perspectives on whether nonhuman animals are moral. Interestingly, they held exactly opposite views: Zhu Xi believed that certain actions on the part of nonhuman animals manifest moral values, whereas Jeong Yakyong claimed that none of the actions of nonhuman animals has moral value. In comparing their views, I introduce Mark Rowlands’ distinction between ‘moral subjects’ and ‘moral agents.’     

The Effect of Transparency on Framing Effects in Within‐Subject Designs

A long‐lasting assumption about the framing effect is that if the participants discover the purpose of the experiment in a within‐subject design, then this test transparency would trigger them to override their initial answer and make coherent choices. For this reason, researchers try to mask the connection between the two parts of the test by inserting filling questions or a time delay between the two parts of the test. In this research, we explored the extent to which these customarily used masking solutions are effective in increasing test sensitivity for the framing effect. In three experiments, we assessed the effect of masking on the tests of the attribute framing and the risky‐choice framing effects. Contradicting the general belief, our results indicate that these effects are already measurable without any masking or delay and we found no convincing evidence that the attempts to decrease task transparency provide worthwhile benefits for general tests of the effect. Beyond their practical relevance, the results question whether the test is a good measure of coherence rationality and better suit those accounts that suggest that the two parts of the framing tasks cannot be regarded as identical.

4PLRT模型与3PLRT模型在瑞文标准推理测验中的比较研究

研究目的：考察反应时与智力的关系以及通过模型对比考察4PLRT模型特性。方法：以瑞文标准推理测验为例,对4PLRT模型与3PLRT模型作比较研究。结论：（1）项目时间参数与难度参数正相关,可以依据时间参数将瑞文标准测验划分成三大部分。（2）能力估计结果比较：由于项目参数和被试速度参数的作用,CTT条件下能力相等的不同被试在计时与非计时条件下存在差异。（3）关于被试的答题策略：被试会基于自身能力而充分权衡时间与准确性的关系。这两种不同模型下被试的能力值之间的比较也说明了时间是一个重要的智力评估因子。     

Which Scientificity for the social Sciences?

Since their emergence in the nineteenth century, the epistemology of social sciences has oscillated from aiming at the classical model of scientificity to emphasizing its own specificities. We argue here that the existence of unambiguous, well defined objects has allowed discoveries and cumulativity in the natural sciences. Whereas, in the social sciences, the term is most often used in a metaphorical meaning, as it represents a basically fluid and changing reality. Its apprehension partly depends on the emotional/intellectual identity of the researcher, which makes it difficult to achieve a full consensus. Yet, beside real, natural or created objects, we do find structures, regularities and objectivations in society.
