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
Criteria and Indicators for Sustainable Forest Management of National Forest District—A Case Study of Hsin-Chu Forest District
No full text永續森林經營準則與指標，可作為評估森林經營是否朝向環境、社會、經濟三面向之永續的度量工具。林務局近年來推行森林生態系經營原則，應用於林區之森林經營計畫，期望以永續森林經營方式，發揮其公益與經濟效益。國有林區森林經營計畫目標，以中央政府訂定之森林經營原則擬定目標，依當地森林情況及當地居民對社會、經濟之需求，制定林區森林經營計畫書，並訂定評估達成績效之準則與指標。
本研究選定新竹林區管理處所編訂林區森林經營計畫書為個案研究之資訊，研究發現新竹林區森林經營計畫之經營準則與指標，無法反應森林經營是否達成社會期望森林永續之目標。現有國有林森林資源調查、事業區檢訂調查、永久樣區等資料內容未具提供林區永續森林經營準則與指標度量時之所需資料。因此進行適應性經營之程序要素分析，同時擬訂新竹林區永續森林經營計畫準則十一項及指標二十八個。期望提供今後持續研發改善經營準則與指標之基礎。The criteria and indicators of sustainable forest management could be used to evaluate the three dimensions of sustainability including environment, society, and economy. In order to further the benefits of public welfare and economy from the sustainable forest management, Taiwan forest Bureau (TFB) implemented recently the national forest management plan according to the priciples of forest ecosystem management.
Following the TFB’s criteria and indicators, the objectives of the forest district management were to balance the local condition of the forest with the economic and social demand of the local resident, and to conceive the forest district management plan and new criteria to evaluate the efficiency of the management performance.
This study chose the forest management plan of Hsin-Chu forest district as a case, and found that the criteria and indicators used in the plan were incapable of fulfilling the social expectation of forest sustainability. In addition, we found that as a measurement of the criteria and indicators of the forest district management plan, the available data of national forest resource survey,the revised inventory system of working circle, and permanent sample plots of stand, all of then could not supply the desired timing information of forest district.
For this reason, this study analyzed the process factors of adaptive management and established 11 criteria and 28 indicators for the sustainable forest management of Hsin-Chu forest district.目 錄

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
