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
Evaluación de riesgos para la industria de llenado de gas licuado de petróleo utilizando lógica difusa y análisis de peligros y operabilidad
Full text linkThe object of this study is to integrate Hazard and Operability (HAZOP) analysis and Fuzzy Logic to improve risk assessment in the Liquefied Petroleum Gas (LPG) filling industry. the research introduces a new approach to resolve the uncertainties and imprecise information inherent in traditional risk evaluation methods. Using HAZOP, a qualitative analysis conducted by the experts of industry identifies potential process deviations and hazards, categorized by impact type such as fire, explosion, and environmental damage. Fuzzy Logic, quantifies these risks by evaluating the likelihood and consequences of accidents using linguistic variables like "high," "medium," and "low." The simulation of different parameters considers various scenarios, including the interplay of consequence severity, event frequency, and detection capability on overall risk using model fuzzy-Hazop. The results provide more precision and actionable risk assessments, showing the potential of the combination of Hazop and fuzzy logic for safety measurement in the LPG filling process. The study concludes HAZOP with fuzzy logic evaluates risks in uncertain conditions, offering an alternative for clearer, decision-making in risk-based design processes.El objeto de este estudio es integrar el análisis de Peligros y Operabilidad (HAZOP) y la Lógica Difusa para mejorar la evaluación de riesgos en la industria de llenado de Gas Licuado de Petróleo (GLP). La investigación introduce un nuevo enfoque para resolver las incertidumbres y la información imprecisa inherente en los métodos tradicionales de evaluación de riesgos. Utilizando HAZOP, un análisis cualitativo realizado por los expertos de la industria identifica posibles desviaciones del proceso y peligros, categorizados por tipo de impacto como incendio, explosión y daño ambiental. La Lógica Difusa cuantifica estos riesgos evaluando la probabilidad y las consecuencias de los accidentes usando variables lingüísticas como "alto", "medio" y "bajo". La simulación de diferentes parámetros considera varios escenarios, incluyendo la interacción de la severidad de las consecuencias, la frecuencia del evento y la capacidad de detección sobre el riesgo total usando el modelo fuzzy-Hazop. Los resultados proporcionan evaluaciones de riesgo más precisas y accionables, mostrando el potencial de la combinación de Hazop y lógica difusa para la medición de seguridad en el proceso de llenado de GLP. El estudio concluye que HAZOP con lógica difusa evalúa riesgos en condiciones inciertas, ofreciendo una alternativa para una toma de decisiones más clara en procesos de diseño basados en riesgos
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
SOPHROLOGY AS A NEW MODEL FOR ACCOMPANIMENT OF AFRICAN MANAGERS, WHAT PROSPECTS?
No full text<p>The role of the manager within the company is not a long quiet river, purpose rather a turbulent river in which the manager must have the capacity for adaptation to live in harmony the permanent change or the only certainty that we can have is that the company will continue to change, especially with the digital transformation and artificial intelligence. The main purpose of our article consists in the proposal of a model of accompaniment of individual and collective based on sophrology. On the one hand for the control of stress within the company which is in constant evolution, on the other hand, to learn how to manage the change with serenity, develop self- confidence, and guide the intentionality toward the actions of the future by the techniques of relaxation dynamics of Caycedo.</p>
