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
Removing Hidden Barriers: Using CHAT to Examine How Women Shape Their Military Experience
Get PDFUsing Critical Military Studies (Basham & Bulmer, 2017; Duncanson & Woodward, 2016), this exploratory case study analysis describes how women officers made sense of their gendered experience within the military, and uses agency, as defined by Post-structural feminism (Davies and Gannon, 2005), to highlight how women are shaped by their environment. The purpose was to both observe how women officers perceived military gender beliefs and practices and analyze how those perceptions shaped how they learn to participate in the military, as well as to analyze how those experiences helped them reshape gender beliefs and practices within the military. I also used Cultural-Historical Activity Theory (CHAT) (Engestrm, 1996, 2001, 2014; Sawchuk, 2003) to describe how women officers learn to participate within the military by observing their actions and motives within their overall activity of becoming an officer and then observing the resolution of contradictions found within that activity. I observed six U. S. Air Force women officers attending Air Command and Staff College. Even though the U. S. Air Force recently removed barriers for women seeking to work in careers historically offered only to men, women described several hidden barriers to their participation that continued to thrive within the military culture. This forced women to perform adaptive acts of resistance like avoidance and acceptance, as well as over-preparing and over-excelling, which could have long-term impacts that could distance men and women officer more from each other and discourage inclusivity. If the U. S. Air Force intends to formulate policy regarding the removal of barriers, it needs to also address cultural barriers that sometimes remain hidden yet are deeply rooted in the cultural expectations of what it means to be a member of the military forces
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
Performance of the NSSL hail detection algorithm for multicell storms over the Coastal Southern Plains
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 57-59).Issued also on microfiche from Lange Micrographics.A study of the National Severe Storm Laboratory's (NSSL'S) Hail Detection Algorithm (HDA) has been performed for over 20 different multicell storm systems that occurred over the coastal region of the southern Great Plains. Since the HDA was developed using a data set mostly from the Central Plains where many of the thunderstorms are supercellular, this study addresses the regional and storm morphological influences on the algorithm performance. To enable use of ground validation from spotter networks, only the severe hail category was studied. While the NSSL HDA performed quite well in most instances, there was a tendency for the algorithm to over-warn for severe hail. Certain adjustable parameters within the HDA were tested for accuracy and optimized for the League City National Weather Service Office in Houston, Texas. These parameters include the Warning Threshold Selection Model (WTSM), the optimum population density threshold, and the Probability of Severe Hail (POSH) function
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
