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
Sleep Disturbance in Patients with Burning Mouth Syndrome: A Case-Control Study
Full text linkAIM:
To examine sleep complaints in patients with burning mouth syndrome (BMS) and the relationships between these disturbances, negative mood, and pain.
METHODS:
Fifty BMS patients were compared with an equal number of healthy controls matched for age, sex, and educational level. The Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Hamilton Rating Scales for Depression (HAM-D) and Anxiety (HAM-A) were administered. Descriptive statistics, including the Mann-Whitney U test and hierarchical multiple linear regression analyses were used.
RESULTS:
BMS patients had higher scores in all items of the PSQI and ESS than the healthy controls (P < .001). In the BMS patients, a depressed mood and anxiety correlated positively with sleep disturbances. The Pearson correlations were 0.68 for PSQI vs HAM-D (P < .001) and 0.63 for PSQI vs HAM-A (P < .001).
CONCLUSION:
BMS patients reported a greater degree of sleep disorders, anxiety, and depression as compared with controls. Sleep disorders could influence quality of life of BMS patients and could be a possible treatment target
Socio-demographic characteristics and pain in 75 Burning Mouth Syndrome patients
No full textTo examine socio-demographic and clinical characteristics in a subset of patients with Burning mouth Syndrome (BMS) and to analyze the relationships between these variables and pain. Methods: 75 subjects enrolled during the period from May 2012 to November 2012. Demographic characteristics and clinical information including age, sex, educational level, marital status, job status, age at disease onset, oral symptoms and triggers were collected. To assess pain, the Visual Analogue Scale (VAS) was performed (fig 1).
Results: Descriptive statistics, the Pearson Chi square tests, the Kruskal Wallis non-parametric tests and the Spearman bivariate correlation were used.The patient age ranged from 18-83 with a mean age of 61.17 (+/-11.75) and a female predominance of 3:1. The age at disease onset was 56.75 (+/-12.01). A lower educational level (8.57+/-4.95), and a high percentage of unemployment (80%) were found (table 1). There were no statistically significant differences in the VAS scale between males and females (p value 0.597) and in marital status (p value 0.495) but only in job status (the median and inter-quartile were 7-4 and 5-3 for unemployed and employed respectively; p value 0.019*) and in age at disease onset (Spearman correlation was 0.279; p value 0.015*). Table 2 and table 3 show the symptoms and triggers reported by the patients . Table 4 and table 5 show the dependence analysis of symptoms and triggers versus gender, marital status, job status, age, educational level and age at disease onset.
Conclusions: The prevalence of BMS is higher in women, with a lower educational level, who are married and unemployed. Pain is higher in the unemployed. In addition, there was a diagnostic delay of about four years which modified the perception of pain. Clinical Relevance: A lower educational level, unemployment and diagnostic delay could
influence clinical outcomes in BMS
