The final version of the paper is available at: http://dx.doi.org/10.1007/s11192-007-1823-8 (www.springerlink.com)[Introduction] Publication delay, chronological distance between completion of a scientific work and distribution of its achievements as a peer reviewed paper, is a negative phenomenon in scientific information dissemination. It can be further subdivided in successive stages corresponding to the peer review process and the technical preparation of accepted manuscripts. Formal online posting in electronic versions of journals has been considered as a shortening of the process.[Objectives] To determine publication delay in a group of leading Food Research journals, as well as factors affecting this lag and also to compute the effect of formal online posting on the distribution of papers in electronic form. Secondary objective is also to study the possible effect of informal posting of papers through some repositories on the publication delay in the field.[Methods] 14 Food Research journals were selected and 4836 papers published in 2004 were examined. Dates of first submission, submission of revised manuscripts, acceptation, online posting and final publication were recorded for each paper.[Analysis] Data collected were analyzed using SPSS and SigmaPlot. Parametric correlation between some variables was determined and ANOVA was performed with BMDP package for significance analysis of differences among journals.[Results] Average publication delay of papers submitted to the set of selected journals is 348 ± 104 days, with European Food Research and Technology and Journal of Agricultural and Food Chemistry showing the shortest delays. Total delay strongly depends on the peer review process. On average, 85.75 % of manuscripts are corrected prior to their acceptance by journals. Online posting of papers prior to their print publication reduces total delay in about 29 %. On average, a paper is posted online 260 days after its submission to the set of journals.[Conclusions] Publication delay of papers is strongly dependent on the peer review process, which affects most of the manuscripts in the Food Research field. Advanced online publication through formal posting at the editor’s sites only slightly reduces the time between reception and final publication of papers.Peer reviewe

[[alternative]]The study of publication lag in Library and Information Science journals

碩士[[abstract]]本研究從時間管理的角度探討學術期刊出版速度，研究目的為瞭解圖書資訊學領域期刊的出版時滯，以收錄於2013年版 Journal Citation Reports (JCR) 中主題分類為資訊科學與圖書館學 (IS&LS) 領域的期刊為研究對象，利用書目計量學方法分析其於2008年、2011年與2012年所出版的期刊論文之出版時滯的概況與變化、特性、開放取用與電子預印本機制、以及與影響係數、5年影響係數、即時指數及被引用半衰期等期刊評鑑指標之間的關係。 本研究結果顯示：出版時滯概況方面，由於在本研究範圍內的期刊 出版時滯數據散布範圍廣，故討論出版時滯不能僅論述其平均值，亦須討論其他數值，本研究範圍內期刊在2008年、2011年與2012年三個年度平均出版時滯分別為428.13天、395.18天、412.56天，中位數分別為398天、331天、362天，25百分位數分別為279.75天、235.75天、264.25天，75百分位數分別為524天、510天、504.5天，眾數分別為353天、258天、456天，表示該領域出版時滯約集中於250天至450天之間。而出版時滯特性部分，不同出刊頻率、出版者、期刊主題、文獻類型、文章篇幅、開放取用期刊與出版時滯皆有顯著相關。另外，本研究結果顯示，提供電子預印本機制期刊在2011年、2012年的出版時滯比2008年大幅縮短，同一段時間也比一般期刊的出版時滯更短，顯示其傳播速度更快，亦表示電子預印機制確實對縮短出版時滯有所助益。分析本研究範圍內期刊出版時滯與期刊評鑑指出版時滯與影響係數、即時指數均無達到統計水準上的顯著關係，但與5年影響係數、被引用半衰期具有相關性。 根據研究結果所提出的建議包括：圖書資訊學領域中各期刊應提供計算出版時滯之基礎日期、並力求縮短出版時滯以及提供電子預印本機制。[[abstract]]This study was mainly to investigate the publication speed of scholarly journals. This study was conducted primarily to investigate the effect of publication lag, defined as the time between submission and publication, on Library and Information Science journals. This study focused on journals in the categories of Information Science & Library Science (IS&LS) in the 2013 edition of Journal Citation Reports, and those published in 2008, 2011 and 2012. The study using bibliometric methods to analyzed the publication lag of current condition, characteristics of publication frequency, publishers, subject categories, article types, and article lengths, Open Access (OA) and in-press , and journal indicators of Impact Factor (IF), 5-year Impact Factor (5Y-IF), Immediacy Index (II), and Cited Half-Life. The results of this study were as follows: (1) In the scope of this study, the condition of publication lag has distributed widely, therefore the average value was not discussed only. In the publication years of 2008, 2011, and 2012, the average publication lag was 428.13, 395.18, and 412.56 days; the median was 398, 331, and 362 days; the 25th percentile was 279.75, 235.75, and 264.25 days; the 75th percentile was 524, 510, and 504.5 days; and the mode was 353, 258, and 456 days, respectively. The publication lag range was between 250 and 450 days. (2) Significant differences were observed in publication lag and publication frequency, publishers, subject categories, article types, article lengths. (3) A significant difference was observed in publication lag and OA journals. However, the appearance of electronic in-press publication did substantially shorter the publication lag in 2011 and 2012 than in 2008, likewise, in-press publication exhibited a shorter publication lag than traditional publication. (4) Significant correlations were observed in publication lag and 5Y-IF, Cited Half-Life, but not for the IF and II. Suggestions based on the results are as follows: (1) Journal publishers should provide dates about counting publication lag, especially submission and acceptance dates. (2) Journal publishers should make efforts to shorten publication lag. (3) Journal publishers should offer in-press publication.[[tableofcontents]]第一章 緒論 1 第一節 問題陳述 1 第一節 研究目的與問題 3 第二節 研究範圍與限制 4 第三節 名詞解釋 5 第二章 文獻探討 9 第一節 學術傳播與學術出版 9 第二節 出版時滯 13 第三節 學術期刊評鑑指標與出版時滯 21 第三章 研究設計與實施 25 第一節 研究設計 25 第二節 研究對象 35 第三節 研究步驟與實施程序 38 第四章 研究結果與分析 41 第一節 出版時滯之概況與變化 41 第二節 出版時滯之特性 50 第三節 開放存取期刊及電子預印本之出版時滯 68 第四節 出版時滯與期刊評鑑指標 71 第五章 結論與建議 75 第一節 結論 75 第二節 建議 79 第三節 對未來研究之建議 80 參考文獻 82 附錄 87 附錄一2013年JCR IS&LS 領域期刊出版相關日期表 87 附錄二 各期刊出刊次數與出版文章數量 90 附錄三 審查階段之時滯 99 附錄四 技術階段之時滯 101 附錄五 刊期-時滯指數 103 表次 表2-1期刊出版時滯之相關研究 17 表2-2美國心理學會期刊出版時滯 18 表2-3美國統計學會期刊出版時滯 19 表3-1研究對象出版資訊 27 表3-2出版單位類型 31 表3-3各期刊出版時滯試算結果表 34 表3-4刊期-時滯指數試算表 34 表3-5轉換出刊頻率單位 35 表3-6提供出版時滯相關日期之期刊數量 35 表3-7出刊頻率變動表 37 表4-1期刊出版資訊與主題分類 42 表4-2脫刊之出版時滯 44 表4-3各期刊出版之論文數量 45 表4-4各期刊出版時滯（N= 4,181） 47 表4-5各期刊出版時滯（N=4,115） 54 表4-6審查階段為零之期刊論文數量 56 表4-7不同出刊頻率之出版時滯 58 表4-8不同單位類型之出版時滯 61 表4-9不同出版地之出版時滯 62 表4-10學科主題數量之出版時滯 63 表4-11各文獻類型之出版時滯 64 表4-12各期刊之期刊論文篇幅 67 表4-13開放存取期刊之出版時滯 68 表4-14出版模式之出版時滯 70 表4-15出版時滯與 IF 及 5年 IF之相關性 72 表4-16出版時滯與 II 及被引用半衰期之相關性 73 表4-17學科領域排名之出版時滯 74 圖次 圖2-1歧異出版時滯定義示意圖 15 圖4-1出版時滯分布 (N=4,181) 46 圖4-2出版時滯分布 (N=4,115) 49 圖4-3各年份出版時滯分布 50 圖4-4各期刊出版時滯分布 53 圖4-5各年份審查階段與技術階段比率分布圖 57 圖4-6各出刊頻率之出版時滯分布圖 57 圖4-7各期刊刊期-時滯指數分布圖 59 圖4-8不同單位類型之出版時滯分布 60 圖4-9各出版地之出版時滯分布 61 圖4-10各學科主題數量之出版時滯分布 63 圖4-11各文獻類型之出版時滯分布 64 圖4-12各期刊文章篇幅分布 66 圖4-13期刊開放存取方式之出版時滯分布 68 圖4-14出版模式之出版時滯分布 70 圖4-15學科領域排名之出版時滯分布 74[[note]]學號: 600000060, 學年度: 10
