Wing dimorphism of Amantis nawai (Shiraki, 1908) (Mantodea: Mantidae): male A. nawai in Taiwan possesses two wing morphs
Yamasaki (1980) 指出台灣地區的名和異跳螳 (Amantis nawai (Shiraki, 1908)) 雄蟲為長翅型 (macroptera),但日本卻只有微翅型 (microptera) 雄蟲存在,因此認為台灣與日本的名和異跳螳應屬於不同物種。實際上,台灣同時具有長翅型及微翅型雄蟲的分布。我們發現兩種翅型雄蟲不僅外表形態 (除了翅膀) 類似、生殖器形態也幾乎沒有差別,而且共域、分布季節重疊,更重要的是長、微翅型雄蟲子代可出自同一對親代。以粒線體 COII 序列建構的親緣關係樹、長、微翅型雄蟲間的族群分化指數 (FST = 0.040)、及遺傳距離 (D) 均顯示不同翅型雄蟲間並無分化的情形出現。我們的試驗結果指出不同翅型名和異跳螳雄蟲應為同一物種,這是螳螂目第一次紀錄到翅的二型性現象。以鄰接法及最大簡約法建構的親緣關係樹符合地理分布,名和異跳螳可分為五個族群,包括台灣北部 (N)、西北部 (NW)、西南部 (SW)、東部族群 (E) 及日韓 (JK) 族群,粒線體 COII 序列分析顯示日韓與台灣的名和異跳螳屬於同一物種,且與台灣東部親緣關係最近。台灣地區各族群間的遺傳分化極大 (FST = 0.684-0.741),可能因為本試驗捕捉的螳螂個體多為散佈能力不佳的微翅型所致。Yamasaki mentioned that male Amantis nawai (Shiraki, 1908) (Mantodea: Mantidae) is micropterous in Japan while macropterous in Taiwan. Based on different wing morphs, Yamasaki suggested that A. nawai in Taiwan and Japan should be classified into different species. However, this study reveals that micropterous and macropterous males in Taiwan are sympatric, and the offspring of both forms come from the same parents. Phylogenetic trees based on mitochondrial cytochrome oxidase II (COII) sequences do not distinguish the two wing morphs. Fixation index (FST = 0.040), and genetic distance (D) reveal no or little differentiation between different wing morphs. This result suggests that macropterous and micropterous male A. nawai in Taiwan belong to the same species. This is the first record of wing dimorphism in Mantodea. According to phylogenetic trees, and geographic distribution, A. nawai were separated into five populations, including north region (N), north-west region (NW), south-west region (SW), east region (E) of Taiwan, and Japan-Korea region (JK). Molecular analyses support the notion that A. nawai in Taiwan, Japan, and Korea should be the same species. Moreover, A. nawai of Japan-Korea region are more related to the eastern population of Taiwan. Fixation index (FST = 0.684-0.741) indicate that the four populations in Taiwan are highly differentiated. It may result from most collected samples are microptera with limited dispersal ability.中文摘要

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
