== Weak evidence for determinants of citation frequency in ecological articles / Padial & et. al. (2010)== **Citation** - Padial, A., Nabout, J., Siqueira, T., Bini, L., & Diniz-Filho, J. (2010). Weak evidence for determinants of citation frequency in ecological articles. Scientometrics, 85(1), 1-12. **Keyword** - 生態論文引用頻次決定因素的弱證據 ==Abstract== * 背景: 引用頻次(citation frequency)被認為是學術出版評量 的 有偏差替身。然而,以往此類研究都是基於引文的小樣本 且 基於顯著性的假設檢驗。 * 研究設計: 以資訊理論架構,評估不同生態學期刊的引用頻次預估。 * 研究假定: 引文頻次的計次預估(如,作者數、文章長度)只使用了總體的一小部份。 * 資料源: 17,363 articles published between 1991 and 2007 in six ecological journals indexed in Thompson-ISI database (http://www.webofscience.com): Oecologia, Oikos, Journal of Animal Ecology, Journal of Ecology, Ecology and Ecology Letters. * 結論: 偏差在生態學引文中並不大。但若想持續深度量化的研究文章科學相關性,必須進一步了解文章為何被引用。 ===what is the "biases" in this article=== 是引用頻次量化研究所描繪的論文引用現況所呈現的「偏差」(biases in citation of article),這些偏差並不符合高引用的論文即該文章與主題相關性;並非探究論文引用頻次計算與現況不符的「誤差」 Variables: # 期刊論文的頁數 number of pages # 期刊論文的作者數 number of authors # 期刊論文的類型 publication type (letter, note, research article or review) # 期刊論文作者的國別 reprint author’s country # 期刊論文作者的第一語言 author’s native language (native English speaker or not) # 期刊論文的第一作者的論文出版數量 number of articles of the first author # 期刊的標題 journal title # 期刊內論文國別數量 number of countries 排除掉的變數: # 已出版年份 # 自我引用。根據資料集中,自我引用與非自我引用的 Pearson’s 相關係數為 0.6 (Pearson r = 0.60; n = 100) # topic of the research # sample size of the study # number of Institutes or Universities (與作者數量有 Pearson’s r = 0.63; n = 100 的相關) # study outcome # 作者說 they are nearly impossible to analyze in a large dataset 評估標準 Akaike Information Criterion (AIC) 赤池資訊量標準 ===Citation frequency 引文頻次=== * 引文頻次(Citation frequency)可被視為一種正式,但有爭議的的量化期刊論文整體影響力或科學期刊相關性的方法。\\ Citation frequency can be considered a formal, albeit controversial, way to quantify the overall impact of an article or the relevance of a scientific journal (Garfield 1972). ** 文獻中針對引文偏差有不同的看法\\ the literature is full of divergent opinions about biases in citation, highlighting the great interest about the issue (Garfield 1972; Leimu and Koricheva 2005a, b; Borsuk et al. 2009; Lortie et al. 2007; Ball 2008). ==Note== * 作者:「科學相關性」=「品質」 == Note == == Metadata/Backlinks == {{backlinks>.}} {{tag>scientometrics}} **file link** - [[google.s>padial a. nabout j. siqueira t. bini l. diniz-filho j. 2010 . weak evidence for determinants of citation frequency in ecological articles|Google Schloar]], [[xxcfile>padial a. nabout j. siqueira t. bini l. diniz-filho j. 2010 . weak evidence for determinants of citation frequency in ecological articles|XXC]]
