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
Quantitative study of the causal relationships among the EFQM model 2020 criteria in the Greek public sector context
Full text linkThis study aims to apply the European Foundation for Quality Management (EFQM) Model 2020 in the Greek Public Sector context and investigate the causal relationships between the model’s criteria. The research uses a structured questionnaire based on the self-assessment tool and the guidelines on the concept and structure of the EFQM Model 2020, translated from English into Greek using forward-backward translation. Two focus groups and a pilot study were conducted to ensure the validity and reliability of the questionnaire. Subsequently, a large-scale quantitative research was conducted using Partial Least Square Structural Equation Modelling (PLS-SEM) to test the research hypotheses on a national sample of 177 managers from public administrative services. The study results indicate that the EFQM Model 2020 is indeed a reliable and valid framework for the study of the public sector and reveal significant relationships between the model’s criteria. The study is one of the first comprehensive investigations of the relationships between the EFQM Model 2020 criteria in Europe and, therefore, provides insights into the understanding of the model. As this research was geographically limited, the findings should be treated and generalised with caution, and further research should be conducted in different contexts
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
L'impacte dels fets polítics sobre els models conversacionals dels blocs: dos casos de Grècia
No full textEls blocs s’estan convertint en una de les principals fonts de
comunicació, una bona manera de difondre noves idees, produir un públic ben informat i fomentar la participació popular en els processos polítics. Aquest article analitza com es
debaten a través dels blocs dos fets polítics recents sobre el
Moviment Socialista Panhel·lènic. L’article utilitza la teoria de
les xarxes socials i l’anàlisi estadística per determinar si la
polarització política es reprodueix en els blocs en el cas grec.
L’article també analitza com diferents fets polítics tenen diferents impactes sobre la polarització de la comunicació política dels blocaires. Les dades obtingudes indiquen que la polarització es reflecteix en els models conversacionals dels blocs.
Els episodis de debats estan associats amb xarxes socials de
blocs més polaritzades.Blogs are becoming a major source of communication, a good
way of circulating new ideas, producing a well-informed
public and helping people's participation in political processes. This paper studies how two recent political events about
the Pan-Hellenic Socialist Movement, are discussed through
blogs. It uses Social Networking Theory and Statistical
Analysis to examine whether political polarization is reproduced in blogging, for the Greek case. The paper also considers
how different political events have a different impact on the
polarization of bloggers' political communication. Findings
suggest that polarization is reflected in blogs’ conversational
patterns. Debate events are associated with more polarized
social networks of blogs.Los blogs se están convirtiendo en una de las principales
fuentes de comunicación, una buena manera de difundir nuevas ideas, producir un público bien informado y fomentar la
participación popular en los procesos políticos. Este artículo
analiza cómo se debaten a través de los blogs dos acontecimientos políticos recientes sobre el Movimiento Socialista
Panhelénico. El artículo utiliza la teoría de las redes sociales
y el análisis estadístico para determinar si la polarización
política se reproduce en los blogs en el caso griego. El artículo también analiza cómo diferentes acontecimientos políticos
repercuten de forma distinta sobre la polarización de la
comunicación política de los blogueros. Los datos obtenidos
indican que la polarización se refleja en los modelos conversacionales de los blogs. Los episodios de debates están asociados con redes sociales de blogs más polarizadas
Connectivity Practices and Activity of Greek Political Blogs
No full textThis paper uses Social Network Analysis indexes to study Greek political blogs. The indexes describe bloggers’ community recommendations, centrality and bloggers’ attempt to form spheres of influence. Five Social Network Analysis indexes are used: incoming links, normalized betweenness, outgoing links, number of 1-cliques a blog belongs to, and size of blog’s ego-network. By recording 127 Greek political blogs, the paper finds that there are two distinct blog performance properties regarding connectivity: Only a few blogs serve as authority blogs having many incoming links and centrality, while a few others try to expand their influence territory by having many outgoing links and forming larger 1-cliques and ego-networks. Next, the paper associates the proposed indexes with blogs’ and users’ community activity. Authority blogs present high blog activity and users’ community activity, as well. These are recorded by large numbers of posts and comments to the blog posts, respectively. It is shown that blogs, which strive to expand their network by using many outgoing links are more likely to link to the authority blogs. Content analysis reveals that authority blogs provide news and information and promote discussion to a much higher degree compared to the overall Greek political blogosphere
