The assessment trials of new maize germplasm heterotic groups were included 18 crosses between 9 inbred testers and the two targeting varieties, ‘GX1F’ and ‘GX1M’. The kernel yield of these 18 testcross hybrids were from 6,760 to 9,672 kg ha-1, and the top 5 crosses with high kernel yield were Hi31 × GX1F, Hi31 × GX1M, 888M × GX1F, 888M × GX1M, and UH13 × GX1F. The inbred testers, Hi31 and 888M, had better common and special combining abilities. Because the cross of Hi31 and ‘GX1M’ showed the best kernel yield, 25 hybrids from the crosses between the Hi31 tester and the S5 progenies of the ‘GX1M’ variety were developed for the combination assessment and yield trials. The combination assessment trials of 25 hybrids showed that the yields of all hybrids were significantly higher than the control variety ‘TNG No. 1’. The dry kernel yield of the five highest new combinations were from 7.7 to 9.5 kg 9.6m-2, which were increased as 75% to 115% of the dry kernel yield of the ‘TNG No. 1’. In addition, the shelling percentage, ear diameter, and 100-kernel weight of these five hybrids were also better than those of the control variety ‘TNG No. 1’. The trials demonstrated that Hi31 had heterotic relationship to the inbred strains derived from the ‘GX1M’
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Orient from the Home--the Issue of Growing up in Yu-ru Chen''s Practice
No full text台灣少年閱讀的文本題材十分多元，其中奇幻小說贏得青少年最多青睞，蔚為風潮，利用古典奇幻元素書寫的少年成長小說正打開讀者不同於西方奇幻的簇新視野。本論文選取陳郁如的《修煉》套書，文本場域包括：上古時代、現代台灣、古代中國、及架空的異世界等；角色多變，有上古時代的男孩張勉、現代的混血女孩、和出自古籍的精怪與神獸，跨越多元時空，與傳統的修煉、輪迴、功夫……等奇幻元素，交織出與西方作品迥異，饒富嶄新奇幻視野的少年成長小說。筆者擬以家為主軸，分別家的概念、離家的多元與邊緣、變身的別體等三個面向，探討三位主要角色如何在「在家」與「離家」之間進行不同程度的冒險，並思索「家」在生命的各種進程帶來的成長體悟與指涉意義。
第一個面向是從家的角度切入，運用「在家」「離家」「返家」的環形故事結構探討主角張勉在成長中面臨的阻力與助力，並探討家的不同樣貌與成長的關聯。第二個面向探討作者如何呈現混血少女艾美離家後，跨越不同時空，對多元文化的觸動與邊緣世界的理解與適應。第三個面向擬從鳥精莊姝修煉變身的過程，探討莊姝面對愛情、家庭的情感試煉與「家」的生命意涵。
從「家」的概念為出發點，透過三位不同身分主角的成長課題，作者賦予「家」新的時代意義：全球化下的家，已打破傳統的血緣論框架，展現出跨文化、彈性重組的關係組合，於是，經歷成長過程身心的極致淬鍊，抵返的「家」成為生命最終的大圓滿。Reading for Taiwanese teenagers varies; teen fantasy books are the most popular among many genres. The introduction of Chinese classic element in fantasy books brings different perspectives to teenagers who might have only known Western fantasy books. This thesis chooses Yu-ru Chen’s trilogy of “Practice” as the object of my study. Chen’s books describe the scenes of ancient time, modern Taiwan, ancient China, high fantastic world, etc. and use many traditional elements, such as reincarnation and Kung-Fu. Through the features mentioned above, Chen creates teenager initiated novels with a brand new fantastic view and different from western literature works.
This thesis starts from three subjects: the concept of home, the diversification and marginalization of leaving-home, and the feeling of transformation. Observing the protagonists’ adventures when they stay and leave home in the diverse worlds helps teenagers ponder the challenge meanings of “home” in their different life.
First, I analyze the protagonist, Mian Zhang’s growing-up process with the main idea of “home,” such as difficulties he faces and lessons he learns after he leaves home. Second, I focus on the protagonist, Amy, and discuss the diverse worlds that mix different “races” of gods, fairies, goblins, human beings and animals. Such discussion sheds light on the understanding of multi-cultural society and marginalized class in the globalization era. Third, I discuss the practice and transformation process of a bird fairy named Shu Zhuang. The way that Shu Zhuang deals with her lover and family teaches teenagers new meanings of “home.”
This thesis starts from the concept of home. With three protagonists’ growing-up processes, Yu-ru Chen gives a new definition of “home,” a home in the globalization era. This “home” breaks the traditional idea of consanguinity and celebrates a home based on a cross-cultural, more flexible relation. By the re-definition of “home,” the characters in Chen’s novels, as well as teenager in realty, will achieve their ideals of home in their own lives after they overcome challenges in the growing-up process.目次

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
