Study on Enhancement of Production Efficiency and Quality in Mini-potted Kalanchoe
No full text本研究旨在建立長壽花 (Kalanchoe blossfeldiana Poelln.) 小品盆花冬季促進開花技術、夏季育苗技術及觀賞品質提升技術。以 ‘齊兒’ 15/10℃之不加溫處理模擬冬季低溫環境，18、23 及28℃根溫處理可增加開花數，而28℃根溫處理可有效提早開花10.3 日。不耐熱品種 ‘巴黎’ 於冷房控制氣溫25/20℃處理，較夏季以雙層遮陰網處理，其株高、展幅及側芽均顯著較佳，且缺株率也能由33.3%降至5.6%，可提升採穗率。7 個長壽花品種於不同光度環境或澆水頻度對觀賞壽命之影響因品種而異，高光度環境下依品種不同可較低光度環境延長觀賞15.0-30.4 日，‘嬌滴滴’ 及 ‘柏金’ 對低光度環境之耐受性較佳，‘黃襯衫’ 及 ‘泰珍妮’ 則較差；所有品種在不澆水處理下均顯著發生葉片下垂情形，以‘柏金’ 品種對低澆水頻度之耐受性最佳，而 ‘泰珍妮’品種在低澆水頻度落葉及花莖下垂嚴重，觀賞期最短。
This study was conducted to establish these techniques of flowering promotion in winter, seeding in summer and quality enhancement in interior condition of mini-potted kalanchoe. Flower numbers of mini-potted kalnchoe ‘Calandiva Cher’ controlled approximately 18, 23 and 28℃ of root temperature more than which placed in 15/10℃ simulated the low temperature condition in winter. And root
temperature enhanced to 28℃ could earlier flowering 10.3 days effectively. Low heat tolerance variety ‘Paris’ in 25/20℃ cool treatment with better height, width and shoot numbers than double shading nets in summer, and death rate declined from 33.3% to 5.6% and the cutting-rate increased. The potted qualities of seven varieties placed three positions or cared by three watering frequencies
affected by varieties. The longevity of potted kalanchoe under higher light condition varied with varieties, range from 15.0 to 30.4 days. ‘Jodie’ and ‘Berkin’ are more tolerant to low light; ‘Karen’ and ‘Tageina’ are rather poor not. All varieties with no watering treatment, showed leaves wilting. ‘Berkin’ is tolerant to no watering; ‘Tangina’ with few watering and no watering cause leaf dropout, flower stem drooping and shortest longevity
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

Poinsettia is one of the important pot plants in Taiwan. In recent years, the
problems of flowering delay and disorder of plant growth caused by high temperature
have been becoming more serious trend. Introducing the concepts of plant health
management and standard operation procedure into poinsettia culture should improve
its production process in Taiwan. In the present report we introduce the whole process
of health management for pot poinsettia production, including the strategy of varieties
selection, stock plants, propagation, media and nutrition, vegetative growth, height
control, the greenhouse environment, scheduling flowering, pest and disease
management and physiological disorder management etc. Carrying out the standard
operation procedure can exactly enhance the cultivation techniques of producers and
obtain modified management process constantly. Further, poinsettia healthy
management would establish the unique pot poinsettia production technique in
subtropical area, and let us possess the key point for industrial development and
competitive advantage in adjacent areas
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
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
