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
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
Exploratory Mining Of Collaborative Social Content
No full textThe widespread use and growing popularity of online collaborative content sites (e.g., Yelp, Amazon, IMDB) has created rich resources for consumers to consult in order to make purchasing decisions on various items such as restaurants, e-commerce products, movies, etc. It has also created new opportunities for producers of such items to improve business by designing better products, composing succinct advertisement snippets, building more effective personalized recommendation systems, etc. This motivates us to develop a framework for exploratory mining of user feedback on items in collaborative social content sites. Typically, the amount of user feedback (e.g., ratings, reviews) associated with an item (or, a set of items) can easily reach hundreds or thousands resulting in an overwhelming amount of information (information explosion), which users may find difficult to cope with (information overload). For example, popular restaurants listed in the review site Yelp routinely receive several thousand ratings and reviews, thereby causing decision making cumbersome. Moreover, most online activities involve interactions between multiple items and different users and interpreting such complex user-item interactions becomes intractable too. Our research concerns developing novel data mining and exploration algorithms to formally analyze how user and item attributes influence user-item interactions. In this dissertation, we choose to focus on short user feedback (i.e., ratings and tags) and reveal how it, in conjunction with structural attributes associated with items and users, open up exciting opportunities for performing aggregated analytics. The aggregate analysis goal is two-fold: (i) exploratory mining to benefit content consumers make more informed judgment (e.g., if a user will enjoy eating at a particular restaurant), as well as (ii) exploratory mining to benefit content producers conduct better business (e.g., a redesigned menu to attract more people of a certain demographic group, etc.). We identify a family of mining tasks and propose a suite of algorithms - exact, approximation with theoretical properties, and efficient heuristics - for solving the problems. Performance evaluation over synthetic data and real data crawled from the web validates the utility of our framework and effectiveness of our algorithms
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
Addressing the Trajectory of Cultural and Gender Discrimination among Marine Women Officers
Get PDFSeafaring is openly challenging working circumstances for females. For the last twenty-two years, females in western countries have been interested in joining the fleet, but as the captaincy roles aboard, their numbers are minimal compared to other jobs. In every working place, females always face many unusual problems, which are more in seafaring. The manuscript derives the discrimination factors of marine women officers (MWOs) onboard due to cultural (or racial) or being a woman using the experiences of 149 women officers from 18 different countries. Two experiences such as onboard discrimination due to cultural reasons (DDCR) and not being promoted in the company as being women (NPCW) for MWOs are considered the responses in the present study. It was found out that mean DDCR is positively associated with age (P=0.0313), nationality (P=0.0047), current position onboard (P=0.1051), while it is negatively associated with cohabitation (P=0.0137) and type of contract (P=0.0719). Variance of DDCR is negatively associated with male companions\u27 support (P=0.1432). Also, mean NPCW is negatively associated with her male companions\u27 support (P<0.0001), while its variance is positively associated with professional qualification (P=0.1317). It was found out herein that MWOs from other nations (except Spanish) at older ages, second class officers, staying single with temporary contracts are highly discriminated against based on cultural (or racial) reasons. In addition, MWOs with higher male companions\u27 support are very rarely promoted in the company
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
