Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Synthesis of cyanopyridine based conjugated polymer
No full textAbstractThis data file contains the detailed synthetic procedure for the synthesis of two new cyanopyridine based conjugated polymer P1 and P2 along with the synthesis of its monomers. The synthesised polymers can be used for electroluminescence and photovoltaic (PV) application. The physical data of the polymers are provided in this data file along with the morphological data of the polymer thin films. The data provided here are in association with the research article entitled ‘Cyanopyridine based conjugated polymer-synthesis and characterisation’ (Hemavathi et al., 2015) [3]
Variations on the Author
No full text“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
No full textWe 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
Asymmetric Second Order Rotatable Designs (AsymmetricSORDs)
No full textResponse surface designs (RSDs) are widely used for Response Surface Methodology (RSM) based optimization studies, which aid in exploring the relationship between a group of explanatory variables and one or more response variable(s) (G.E.P. Box and K.B. Wilson (1951), ``On the experimental attainment of optimum conditions'' ; M. Hemavathi, Shashi Shekhar, Eldho Varghese, Seema Jaggi, Bikas Sinha & Nripes Kumar Mandal (2022) .``Theoretical developments in response surface designs: an informative review and further thoughts''.). Second order rotatable designs are the most prominent and popular class of designs used for process and product optimization trials but it is suitable for situations when all the number of levels for each factor is the same. In many practical situations, RSDs with asymmetric levels (J.S. Mehta and M.N. Das (1968). ``Asymmetric rotatable designs and orthogonal transformations'' ; M. Hemavathi, Eldho Varghese, Shashi Shekhar & Seema Jaggi (2020) . ``Sequential asymmetric third order rotatable designs (SATORDs)'' .) are more suitable as these designs explore more regions in the design space.This package contains functions named Asords() ,CCD_coded(), CCD_original(), SORD_coded() and SORD_original() for generating asymmetric/symmetric RSDs along with the randomized layout. It also contains another function named Pred.var() for generating the variance of predicted response as well as the moment matrix based on a second order model
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
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
Understanding the psychological experience and perspective of frontline healthcare workers and psychological first aid providers during the covid-19 pandemic: A qualitative study / Hemavathi Shanmugam
No full textBackground: The growing number of coronavirus disease 2019 (COVID-19) cases since
December 2019 has led to burnout and psychological distress among the frontline
healthcare workers (HCWs). In Malaysia, remote Psychological First Aid (PFA) via
teleconsultation was launched to ameliorate the mental health distress among HCWs.
Objectives: The purpose of this study was to understand the psychological experience
and perspective of frontline HCWs and PFA providers as a guide in improvising the
delivery of the remote PFA service during the COVID-19 pandemic.
Methodology: A descriptive qualitative research design based on semi-structured
individual in-depth interviews were conducted with a total of 30 participants from the
University Malaya Medical Centre (UMMC), Malaysia consisting of 20 frontline HCWs
and 10 PFA providers. The study assessed frontline HCW’s experience in handling their
duties, the psychological stress they experienced, their coping strategies as well as their
understanding regarding psychological first aid services. As for the PFA providers, we
assessed their experience in administrating PFA, the challenges they encountered and
their strategies to improve the PFA service. Transcripts were analyzed using Colaizzi's
phenomenological analysis method.
Results: Three themes emerged from the data analysis of frontline HCWs, where they
reported negative emotions in the early stages such as fear, uncertainty, fatigue, and
vi
sadness followed by adaptations of healthy coping strategies. However, frontline HCWs
lacked awareness and showed apprehension to PFA service. As for PFA providers, the
three themes recorded were challenges associated with remote PFA, administrative
difficulties due to lack of PFA guidelines and the need for modification of the existing
PFA services.
Conclusion: Our study suggests that frontline HCWs would benefit from early
psychological assessment and that existing PFA needs to be improvised with follow-up
psychosocial interventions due to the ongoing nature of the pandemic
