The Short Stories of Shen Ya-chih (782?-831?)
No full textShen Ya-chih, an impoverished descendent of the southern aristocracy, is mainly famous as a poet, though he also wrote a number of works of prose fiction. His fiction may be divided into three groups according to the periods in which it was written. In the period before Shen Ya-chih passed his chin-shih examination (814), when it was his ambition to become an historian, he wrote the stories entitled "Biography of Hsi-tzu" 喜子傳 and "Biography of Feng Yen" 馮燕傳, employing the biographical form and a clear, simple style to describe men who are caught in a dilemma. His style in this period is markedly influenced by that of Han Yu, his teacher. The period from the time he passed his examination and became an official until 829 when, having advanced in the bureaucracy and become involved in a political dispute, he was sent into exile, constitutes the second phase of his work, during which his style undergoes a definite change. From this period date the stories I-meng-lu, 異夢錄 Hsiang-chung yüan-chieh, 湘中怨解 Ch'inmeng-chi 秦夢記 and others, all dealing with love, music or dance, espesially as they appear in dreams. They are romances of a fantastic nature and include large numbers of lyric poems woven into the texts. The influence of the poets Yüan Chen 元稹 and Po Chü-i 白居易 is most noticeable in his work of this period. The third period, from the time of his exile to present day Hupeh until his death two years later, is represented by the story entitled "Biography of Kuo Ch'ang" 郭常傳, in which the author, through the biography of a doctor, attacks the corruption of the bureaucratic world of his day. Thus Shen Ya-chih in his works moved from simple biography to romance and fantasy, and in the end returned to satirical potrayals of the contemporary world. He lived at a time when the T'ang romance had reached its peak of development and had begun to decline, and his own works may be said to reflect this process
Sinuladiterpenes a-F, New Cembrane Diterpenes from Sinularia Flexibilis
No full textChromatographic investigation of the octocoral Sinularia flexibilis afforded six new cembrane diterpenes, sinuladiterpenes A-F (1-6, resp.), in addition to four known cembranolides, 11-episinularolide acetate, 11- dehydrosinulariolide, 11-episinulariolide, and sinulariolide . Their structures were elucidated by spectroscopic analysis , especially 2D-NMR and HR-ESI-MS. Compound 2 exhibited significant in vitro cytotoxic activity against human colon adenocarcinoma (WiDr) cell line
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
