    北京大學於2009年入藏一批西漢竹簡,當中醫簡711枚,內容大致分為「醫方目錄」、「醫方甲」、「醫方乙」和「醫經」四類,相關資料可參見李家浩、楊澤生〈北京大學藏漢代醫簡簡介〉一文(《文物》2011年6期)。根據整理者公佈之圖版可知,北大簡第2870簡記有古醫方「秦氏方」,簡文云:「一沺一傅,它惡傷亦可。  .秦氏方。」「秦氏」之名亦見《史記.扁鵲列傳》:「扁鵲者……,姓秦氏,名越人。」因此,過去嘗有學者認為「秦氏」有可能是戰國時期之神醫扁鵲。「一沺一傅」,「沺」於經傳中鮮見,疑應「洒」之誤,具「洗」義。「傅」則屢見於簡帛醫藥文獻中,有「塗抹」之意。在馬王堆漢墓醫書中,「洒」及「傅」二詞經常相連出現,例如〈五十二病方.白處方〉云:「二日,洒,以新布孰暨(摡)之,【復】傅。」又〈雎(疽)病〉云:「日一【傅】樂(藥),【傅】樂(藥)前洒以溫水。」「洒」及「傅」應是古代常見之治療方法。本文擬先借助北大簡「秦氏方」中「一沺一傅」之記述,對「沺」與「洒」之關係作出釐清,然後再結合簡帛醫藥文獻中「洒」及「傅(敷)」之記載,期望能對兩者之性質及應用情況作更進一步之討論。 The Western Han bamboo manuscripts acquired by the Beijing University in 2009 comprise of 711 medical scripts with four categories, namely yifang mulu (醫方目錄), yifang jia (醫方甲), yifang yi (醫方乙) and yijing (醫經). Its reference materials could be found in 'An introduction to the Han medical bamboo scripts of the Beijing University Collection' co-authored by Li Jiahao and Yang Zesheng published in 'Wenwu' (《文物》) issue 6, 2011. According to the pictures provided by collators, bamboo script no. 2870 gives an account of the ancient medical prescription Qinshi Fang (秦氏方), stating that '一沺一傅,它惡傷亦可。 .秦氏方。'. As the name Qinshi could also be found in 'Bianque Liezhuan' (扁鵲列傳) of 'Shiji'(《史記》), scholars therefore considered Qinshi should probably be the ancient doctor Bianque of the Warring States Period.The character tian (沺) in yisa yifu (一沺一傅) is rarely seen in ancient texts. This article thus suggested tian may be a miswrite of sa (洒) with the meaning of 'washing', while fu, commonly found in bamboo and silk medical scripts, should mean 'rubbing'. Jointly-used examples of sa and fu appeared in medical manuscripts of the Mawangdui Han Silk frequently, revealing that both sa and fu should be usual methods of treatment in ancient times. The objectives of this article were to clarify the relationship of the characters tian (沺) and sa (洒) in medical scripts from the Beijing University Collection, and then to conduct a detailed study on the nature and application of sa (洒) and fu (傅) by referring to related narrations in the excavated bamboo and silk medical documents

    談上博簡《鬼神之明》的學派問題

    Guishen zhi Ming ( 鬼神之明) is a section of the published Chu Bamboo Slips of the Warring States Period in Shanghai Museum Collection, which primarily addressed the issue of what the ghosts and deities known and unknown. In terms of its school, some scholar classified it as Mohist work, while some others disagree with that. This article argues that although the bamboo slips mentioned that the ghosts and deities have something they do not know, but the essential thought of this whole section differs from contemporary Confucianism, and have some similarities with the Mohist doctrine. In addition, the logic of this section is also consonant to the theory of Mohist Canons. 《鬼神之明》刊载于上博简第五册,主要讨论鬼神“有所明”与“有所不明”的问题。自竹书发表后,不少学者曾就其学术派别的问题作出论述,当中有认为《鬼神之明》为墨学作品,但亦有持反对意见,以为竹书是反墨、墨学异端甚或是儒学之作。本文透过《鬼神之明》内容的剖析,指出篇中虽然提及鬼神“有所不明”之说,但所反映的思想在本质上实与春秋战国时期儒家的鬼神观有所不同,且部分更与墨家有暗合之处。此外,本文通过篇中思维方式与《墨经》逻辑学说的相参照,提出两者实有不少可比观的地方

    Contributions of tester experience and a checklist guideline to the identification of categories and choices for software testing

    Get PDF
    An early step for most black-box testing methods is to identify a set of categories and choices (or their equivalents) from the specification. The identification is often performed in an ad hoc manner, thus the quality of categories and choices is in doubt. Poorly identified categories and choices will affect the comprehensiveness of test cases. In this paper, we describe several comparative studies using three commercial specifications and discuss the major results. The objectives of our studies are (a) to investigate the differences in the types and amounts of mistakes made between inexperienced and experienced software testers in an ad hoc identification approach and (b) to determine the extent of mistake reduction after discussing the mistakes with the software testers and providing them with an identification checklist. © 2010 The Author(s).published_or_final_versionSpringer Open Choice, 31 May 201

    On the identification of categories and choices for specification-based test case generation

    Get PDF
    HKU CS Tech Report TR 2004-02The category-partition method and the classification-tree method help construct test cases from specifications. In both methods, an early step is to identify a set of categories (or classifications) and choices (or classes). This is often performed in an ad hoc manner due to the absence of systematic techniques. In this paper, we report and discuss three empirical studies to investigate the common mistakes made by software testers in such an ad hoc approach. The empirical studies serve three purposes: (a) to make the knowledge of common mistakes known to other testers so that they can avoid repeating the same mistakes, (b) to facilitate researchers and practitioners develop systematic identification techniques, and (c) to provide a means of measuring the effectiveness of newly developed identification techniques. Based on the results of our studies, we also formulate a checklist to help testers detect such mistakes. © 2004 Elsevier B.V. All rights reserved.postprin

    Observing object lifting errors modulates cortico-spinal excitability and improves object lifting performance.

    PublishedJournal ArticleObserving the actions of others has been shown to modulate cortico-spinal excitability and affect behaviour. However, the sensorimotor consequences of observing errors are not well understood. Here, participants watched actors lift identically weighted large and small cubes which typically elicit expectation-based fingertip force errors. One group of participants observed the standard overestimation and underestimation-style errors that characterise early lifts with these cubes (Error video--EV). Another group watched the same actors performing the well-adapted error-free lifts that characterise later, well-practiced lifts with these cubes (No error video--NEV). We then examined actual object lifting performance in the subjects who watched the EV and NEV. Despite having similar cognitive expectations and perceptions of heaviness, the group that watched novice lifters making errors themselves made fewer overestimation-style errors than those who watched the expert lifts. To determine how the observation of errors alters cortico-spinal excitability, we measured motor evoked potentials in separate group of participants while they passively observed these EV and NEV. Here, we noted a novel size-based modulation of cortico-spinal excitability when observing the expert lifts, which was eradicated when watching errors. Together, these findings suggest that individuals' sensorimotor systems are sensitive to the subtle visual differences between observing novice and expert performance.G.

    Digit-only sauropod pes trackways from China - evidence of swimming or a preservational phenomenon?

    Get PDF
    For more than 70 years unusual sauropod trackways have played a pivotal role in debates about the swimming ability of sauropods. Most claims that sauropods could swim have been based on manus-only or manus-dominated trackways. However none of these incomplete trackways has been entirely convincing, and most have proved to be taphonomic artifacts, either undertracks or the result of differential depth of penetration of manus and pes tracks, but otherwise showed the typical pattern of normal walking trackways. Here we report an assemblage of unusual sauropod tracks from the Lower Cretaceous Hekou Group of Gansu Province, northern China, characterized by the preservation of only the pes claw traces, that we interpret as having been left by walking, not buoyant or swimming, individuals. They are interpreted as the result of animals moving on a soft mud-silt substrate, projecting their claws deeply to register their traces on an underlying sand layer where they gained more grip during progression. Other sauropod walking trackways on the same surface with both pes and manus traces preserved, were probably left earlier on relatively firm substrates that predated the deposition of soft mud and silt . Presently, there is no convincing evidence of swimming sauropods from their trackways, which is not to say that sauropods did not swim at all

    Emergence of scale-free close-knit friendship structure in online social networks

    Despite the structural properties of online social networks have attracted much attention, the properties of the close-knit friendship structures remain an important question. Here, we mainly focus on how these mesoscale structures are affected by the local and global structural properties. Analyzing the data of four large-scale online social networks reveals several common structural properties. It is found that not only the local structures given by the indegree, outdegree, and reciprocal degree distributions follow a similar scaling behavior, the mesoscale structures represented by the distributions of close-knit friendship structures also exhibit a similar scaling law. The degree correlation is very weak over a wide range of the degrees. We propose a simple directed network model that captures the observed properties. The model incorporates two mechanisms: reciprocation and preferential attachment. Through rate equation analysis of our model, the local-scale and mesoscale structural properties are derived. In the local-scale, the same scaling behavior of indegree and outdegree distributions stems from indegree and outdegree of nodes both growing as the same function of the introduction time, and the reciprocal degree distribution also shows the same power-law due to the linear relationship between the reciprocal degree and in/outdegree of nodes. In the mesoscale, the distributions of four closed triples representing close-knit friendship structures are found to exhibit identical power-laws, a behavior attributed to the negligible degree correlations. Intriguingly, all the power-law exponents of the distributions in the local-scale and mesoscale depend only on one global parameter -- the mean in/outdegree, while both the mean in/outdegree and the reciprocity together determine the ratio of the reciprocal degree of a node to its in/outdegree.Comment: 48 pages, 34 figure
