"得荃忘鱼"、渔父哲学与当代道德"救亡"

明末顾炎武曾把易姓改号称为“亡国”,而把道德沦丧称为“亡天下”;清末严复写《救亡决论》一文,为民族救亡大声疾呼。今天中国虽无“亡国”之忧,却有“亡天下”之虞,“得荃忘鱼”的病象,“渔父哲学”的盛行,厚黑之道的猖獗,使“道德救亡”已成为当前中国最迫切的现实课题,中国不应回避也不能头痛医头脚痛医脚地对待这个问题,只有清理历史传统、改造社会生态才是“道德救亡”的唯一出路。     

Laterality effects in the spinning dancer illusion: The viewing‐from‐above bias is only part of the story

The ‘silhouette illusion’, representing the silhouette of a female dancer pirouetting about her vertical axis, is a bistable stimulus created by Japanese web designer Nobuyuki Kayahara. Although the dancer can be perceived as spinning either clockwise or counterclockwise, the clockwise rotation is usually preferred. Troje and McAdam (i‐Perception, 2010, 1, 143) showed that this clockwise bias can be attributed to the tendency to assume a viewpoint from above rather than from below, given that the dancer is portrayed from a vantage point that is not perpendicular to the axis of rotation. Here, we tested whether another possible factor contributing to the observers’ interpretation of this bistable stimulus might be the tendency to perceive movements of the right rather than the left foot. We confirmed both the viewing‐from‐above bias and our hypothesis. The bias to perceive movements of the right leg might be a generalization to lower limbs of a perceptual frequency effect already observed for upper limbs. Such a perceptual and attentional bias towards the right hand/foot could account for the greater ability to predict the outcome of sport actions when observing right‐ rather than left‐limbed movements, and thus the left‐handers' and left‐footers' advantage observed in a variety of interactive sports.     

Free recall and retrieval speed of categorized items by kindergarten children

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.     

认知评价、心理控制感、社会支持与高考压力关系的研究

采用问卷法,随机选取河北省三类中学(重点、普通、私立)324名高三考生为被试,考察了学生对高考的认知评价、心理控制感、社会支持与高考压力的关系.结果表明:(1)重点中学、普通中学学生心理控制感显著高于私立中学学生,女生在社会支持的寻求上显著高于男生;(2)积极认知评价、心理控制感和社会支持与高考压力有显著负相关,而消极认知评价与高考压力有显著的正相关;(3)消极认知评价、心理控制感和社会支持对高考压力有直接影响;而积极认知评价通过心理控制感和社会支持间接影响高考压力.     

70岁高龄男性助孕引发的问题及伦理思考

报道了1例70岁高龄男性的助孕情况,探讨了高龄男性生育现状、高龄男性助孕存在的问题以及助孕易于引发的伦理问题。意在提醒生殖中心工作人员在接诊高龄男性患者助孕时,既要尊重其与配偶的生育权,又要充分告知高龄男性生育给自身、配偶及后代带来的风险。助孕前应加强医患沟通,遵循有利于患者原则、知情同意原则、有利于后代原则,同时接受伦理委员会的监督,严防技术滥用,适时劝导高龄男性患者放弃助孕治疗。     

Satisfiability Decay along Conjunctions of Pseudo-Random Clauses

k-SAT is a fundamental constraint satisfaction problem. It involvesS(m), the satisfaction set of the conjunction of m clauses,each clause a disjunction of k literals. The problem has manytheoretical, algorithmic and practical aspects. When the clauses are chosen at random it is anticipated (butnot fully proven) that, as the density parameter m/n (n thenumber of variables) grows, the transition of S(m) to beingempty, is abrupt: It has a "sharp threshold", with probability1 – o(1). In this article we replace the random ensemble analysis by apseudo-random one: Derive the decay rule for individual sequencesof clauses, subject to combinatorial conditions, which in turnhold with probability 1 – o(1). This is carried out under the big relaxation that k is not constantbut k = log n , or even r log log n . Then the decay of S isslow, "near-perfect" (like a radioactive decay), which entailssharp thresholds for the transition-time of S below any givenlevel, down to S = .     

人与自然和谐的道德基础——古代"天人合一"思想的现代生态伦理启示

人与自然的和谐有着道德基础。古代的“天人合一”思想为我们从道德的视角研究人与自然的和谐,以及建构现代生态伦理观提供了一定的帮助。从道德的意义上,人与自然的和谐中人是道德主体,承担着全部道德责任,其行为是道德评价的对象。人对自然的适应与改造、尊重与利用是辩证的统一。     

孔子与泰德·本顿的生态观之比较

20世纪后半期,人类面临的最突出的问题就是全球性的生态危机和环境问题。摆脱人类生存的困境,走向具有生态持续性的文明社会是中国现代化实践面临的严峻挑战。本文试将孔子和泰德·本顿的生态观加以比较,求同存异,发掘其中蕴含的积极因素。两者在对自然的解读上,强调自然的客观实在性,重视自然的内在价值和对自然规律的遵循;在人与自然的关系上,阐发人与自然的息息相关性和密不可分性,强调二者相互作用。相互影响;在对自然资源的利用上,强调合理地支配和有限地利用自然,承认自然的极限。这些思想为我国生态文明建设提供了有益的借鉴。     

How Do Children Restrict Their Linguistic Generalizations? An (Un‐)Grammaticality Judgment Study

A paradox at the heart of language acquisition research is that, to achieve adult‐like competence, children must acquire the ability to generalize verbs into non‐attested structures, while avoiding utterances that are deemed ungrammatical by native speakers. For example, children must learn that, to denote the reversal of an action, un‐ can be added to many verbs, but not all (e.g., roll/unroll; close/*unclose). This study compared theoretical accounts of how this is done. Children aged 5–6 (N = 18), 9–10 (N = 18), and adults (N = 18) rated the acceptability of un‐ prefixed forms of 48 verbs (and, as a control, bare forms). Across verbs, a negative correlation was observed between the acceptability of ungrammatical un‐ prefixed forms (e.g., *unclose) and the frequency of (a) the bare form and (b) alternative forms (e.g., open), supporting the entrenchment and pre‐emption hypotheses, respectively. Independent ratings of the extent to which verbs instantiate the semantic properties characteristic of a hypothesized semantic cryptotype for un‐ prefixation were a significant positive predictor of acceptability, for all age groups. The relative importance of each factor differed for attested and unattested un‐ forms and also varied with age. The findings are interpreted in the context of a new hybrid account designed to incorporate the three factors of entrenchment, pre‐emption, and verb semantics.
