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
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
Achieving triple treatment goals in multi-ethnic Asian patients with type 2 diabetes mellitus in primary care
No full textIntroduction: Achieving optimal glycated hemoglobin (HbA1c), blood pressure (BP), and LDLCholesterol (LDL-C) in patients mitigates macro- and micro-vascular complications, which is the
key treatment goal in managing type 2 diabetes mellitus (T2DM). This study aimed to determine
the proportion of patients in an urban community with T2DM and the above modifiable
conditions attaining triple vascular treatment goals based on current practice guidelines.
Methods: A questionnaire was distributed to adult Asian patients with dyslipidemia at two primary
care clinics (polyclinics) in northeastern Singapore. The demographic and clinical data for this
sub-population with both T2DM and dyslipidemia were collated with laboratory and treatment
information retrieved from their electronic health records. The combined data was then analyzed
to determine the proportion of patients who attained triple treatment goals, and logistic regression
analysis was used to identify factors associated with this outcome.
Results: 665 eligible patients [60.5% female, 30.5% Chinese, 35% Malays, and 34.4% Indians]
with a mean age of 60.6 years were recruited. Of these patients, 71% achieved LDL-C ?2.6
mmol/L, 70.4% had BP <140/90 mmHg, and 40.9% attained HbA1c ?7%. Overall, 22%
achieved the triple treatment goals for glycemia, BP, and LDL-C control. The major determinants
were the number of diabetic medications and intensity of statin therapy.
Conclusion: Eight in ten patients with T2DM failed to achieve concurrent glycemic, BP, and
LDL-C treatment goals, subjecting them to risks of vascular complications. Primary healthcare
professionals can mitigate these risks by optimizing therapeutic treatment to maximize glycemia,
dyslipidemia, and BP control
Cloud-Based In-Vehicle Air Quality Monitoring System with GSM Module
No full textThe purpose of this study is to develop a monitoring system that not limited to real-time vehicle tracking, but also with the ability to monitor in-vehicle air quality. In vehicle air quality is referred to indoor air quality (IAQ) inside the vehicle cabin which is lacked of awareness among driver nowadays. Previous research indicates that human spend up to 90% of their daily time inside the closed circulated air environment including, the vehicle. Prolonged use of air recirculation inside the vehicle cabin can lead to a gradual accumulation of carbon dioxide (CO2) which may occur the symptoms such as fatigue, headaches, and dizziness even deleterious effects on cognitive function towards the occupants. Vehicle cabin is an enclosed environment to prevent the outdoor air directly flow inside the vehicle cabin. However, when the vehicle speed increases the air pressure will be applied onto the joint of the car body and created some leakages then the outdoor air can flow into the cabin then may change the IAQ. A Global System for Mobile (GSM) communications module is utilised as a proxy to push the aggregated information such as real-time vehicle location, IAQ status and timestamps into the cloud database with an iteration of the 30s. The average time delayed for data to reach the cloud database is approximate 3.6s from the time it transmitted. Through the Android mobile application, the user can observe the in-vehicle air quality with the current location in two optional modes: real-time or historical data. The developed device and system were compared with off the shelf device (AeroQual). The Bland-Altman plot method was applied to validate the result of in-vehicle air quality system. The coefficient of determination (R2) value between these two devices is approximately 0.9. The in-vehicle air quality with vehicle tracking system has been successfully developed and provided a reliable result
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
