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
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

Dentofacial features of obstructive sleep apnoea syndrome (OSAS) among army personnel based in Kelantan
Full text linkObstructive sleep apnea (OSA) is repeated complete or partial upper airway obstruction
during sleep, causing cessation of breathing (apnea) or reduction in airflow (hypopneas)
despite persistent respiratory effort. It occurs in 9% and 24% middle-aged women and men
respectively while obstructive sleep apnea syndrome, OSAS (OSA plus presence of
symptoms such as excessive daytime sleepiness) occurs in 2% and 4% middle-aged women
and men respectively. The objectives of the study were to determine the prevalence of
symptoms of OSAS and the differences in dentofacial features of army personnel based in
Kelantan who are at high risk and low risk of having OSAS, and to fmd factors associated
with the risk of having OSAS. 911 army personnel based in the Des a Pahlawan camp were
randomly selected to answer the Malay version of Berlin questionnaire. The distributions
of symptoms of OSAS were determined and subjects were categorised as being either at
high risk or low risk of having OSAS. Dental study models, lateral cephalometric
radiographs and neck circumference for the determination of the dentofacial dimensions
were taken from 35 high risk and 37 low risk subjects. A proportion of these subjects
underwent overnight sleep studies. Results: 661 questionnaires were returned. The mean
age of total participants was 31.4 years (standard deviation (SD) 6.45) while the mean BMI
was 24.4 kg I m2 (SD 2.47). There was a range of prevalence of the main symptoms of
OSAS with 45 subjects (6.8%, 95o/o CI: 5.0-9.0) categorised in the high risk group for
OSAS. There were no significant differences in age and BW between the 35 high risk and
37 low risk subjects that formed the subsequent comparison groups. The neck
circumference, PNS_P (length of the soft palate), MPT (maximum soft palate thickness),
MPH (distance between the mandibular plane and the hyoid bone), maxillary intermolar
distance, mandibular intermolar distance and middle PAS (posterior airway space) were
significantly different between both groups. There were significant associations between
the following variables and the risk of having OSAS: mandibular intermolar distancePNS_P and MPH. The current study demonstrates presence of symptoms ofOSAS and the
distinct dentofacial features in subjects at high risk of OSAS. This study also confmns that
symptoms of OSAS still exist even without the classical sign of OSAS, i.e. obesity. It also
shows that greater attention should be paid to the evaluation of the dentofacial features in
subjects with a low BMI at high risk for the disorder
Assessing the relationship between technology, organization, environment as factors for big data adoption and organizational impact in Malaysia’s government linked agencies / Hasnah Hashim
Full text linkBig Data Adoption (BDA) is has been found to be effective in increasing the capacity of Malaysia’s Government-Linked Agencies (GLAs) since it offers better opportunities to be competitive through its insights. Even though data analytics are increasingly used by government and public sectors and around the world to enable decision process, however limited attention has been given from the research perspective and matter how it has been implemented in the Government-Linked Agencies, specifically in Malaysia. Started with massive data generated from various process from business activities, BD has great potential to exploit. BD have unique characteristics which able to trans format a lowest cost, reassure organization to gain significant meaning, valuable insights with the existing IT infrastructure in everyday operations
