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
Wages and Promotions in Internal Labor Markets
No full text本文使用一家台灣服務業公司的10年人事資料，來檢測內部勞動市場的假主。首先我們直接利用該公司的工作職稱(job title)、權力階級(authority level)以及管理階級結構圖(hierarchical structure chart)定義層級。接著我們在計算昇遷矩陣之後發現，該公司在擴充與停滯的期間內，昇遷及降職的數率並沒有顯著的差異，而平均降職率則約在2%至8%左右。我們也發現薪資與層級?正相關，但薪資重疊也存在於同一層級內與不同層級之間。另外，由於固定效果模型大幅的削弱了層級對薪資增幅的影響，顯示了天生能力與層級相關之外，也使得錦標賽理論(Tournament Theory)在本文資料中只能得到微弱的支持。在內部勞動民市場與外部勞動市場的互動方面，我們發現地薪資來說，年虛擬變數?一粗顯著的解釋變數：在景氣較差時，薪資減少大約10%到18%左右。此外，外部勞動力則是透過層級較低的新進與離職的管道進入該公司，而內部員工擁有昇遷的優先權。整體證據顯示，內部勞動市場，傳統人力資本，以及景氣波動都會對個人的薪資造成影響。In this paper, an internal dataset for a Taiwanese firm is analyzed. Job title, authority level, and the hierarchical structure chart of the company are used to identify levels. It is found that job transition paths are steady during periods of growth and stagnant. However, demotions are not rare (2%-8% per year). Levels are positively correlated with compensation, but overlap in compensation exists both within and between levels. The level coefficients of the fixed effect model of compensation are much smaller than the OLS results, suggesting that innate ability is correlated with levels and that evidence supporting tournament theory weak. Furthermore, year dummy variables are a set of significant coefficients on explaining compensation. Ports of entry and exit exist, and they are concentrated in the lower levels of the hierarchy. Overall, we find that internal labor markets, the traditional human capital, and the business cycle all affect individual wages
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
