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
Evaluation of patterns of labor progression in Pakistani nulliparous women with spontaneous onset of labor
No full textBackground: Understanding of labor dynamics is evolving, and several population-based studies have examined the normal labor process in different racial groups. This complexity is compounded by changes in maternal characteristics, and obstetric practices overtime. Additionally, labor induction and augmentation practices involving the use of oxytocin and artificial rupture of membranes influence the process of labor. These evolving dynamics necessitate an understanding of current labor progression patterns, which have been introduced by Friedman’s 50 years back and modified by Zhang’s two decades ago.Objective: This study aimed to evaluate the labor progression patterns in nulliparous Pakistani women and compare these patterns with the curves developed by Friedman’s and Zhang.Methodology: This retrospective cohort study was conducted at Aga Khan University hospital. Data was collected using structured proforma from the medical records (years 2021- 2022) of nulliparas, at term, with spontaneous labor onset, cervical dilation of less than 6 cm at admission, and singleton vertex deliveries with no adverse birth outcomes. Our main exposure was spontaneous onset of labor and outcome measures were progressive cervical dilation to construct labor curve, and duration of labor at 50th and 95th percentiles. Statistical analysis was performed using generalized linear mixed method approach with polynomial regression to evaluate predictor variables effect on the cervical dilation. The univariate and multivariable models were constructed. To map impact of progression time for cervical dilation from onset till 10cm, quadratic time variables were generated. A labor curve was plotted using the model estimates. Subgroup analyses were also performed for Syntocinon and epidural use.Results: The characteristics of our study participants (n=309) demonstrated that 89% were primigravida, and 11% had a history of previous miscarriage. The mean maternal age was 26.1 ± 4.0 years, and BMI was 27.7 ± 4.5 kg/m² at admission for delivery. The mean gestational age at admission for delivery was 38.3 ± 1.1 weeks. In 80% of women, labor was augmented with Syntocinon. The procedure of amniotomy was performed in 63% of vi women. Entonox and epidural were mainly used for labor analgesia. The cumulative labor duration from onset to 10 cm dilation was 5.5 hours with 95th percentile of 10.7 hours. The second stage (from 10cm to delivery) was 35 minutes in half of women and with 95th percentile as two hours. In the multivariable model, significant predictors for labor progression included cervical effacement, fetal station, uterine contractions frequency, and progression time. The average estimated change in cervical dilation was 0.5 centimeter (cm) per hour. Fetal head descent was associated with a 0.8 cm change in cervical dilation (95% CI: 0.7, 0.9) while the correlation with contractions\u27 frequency was 0.2cm (95%CI:0.05,0.4). Cervical effacement proved to be a robust predictor for cervical change, with a particularly pronounced effect observed in cases of a fully or nearly fully effaced cervix (0.5cm). We observed a significant interaction between Syntocinon infusion rate and cervical effacement categories. Syntocinon effect on cervical dilation was different for different categories of cervical effacement, indicating significant effect with partial effacement and insignificant with fully effaced cervix. Our labor curve demonstrated gradual progression without a clear inflection point, akin to Zhang\u27s curve. The subgroup analyses regarding Syntocinon augmentation and epidural analgesia highlighted that labor progression was slower in women who received epidural and Syntocinon. Nevertheless, these findings need cautious and thoughtful interpretation.Conclusion: Utilizing a population-based curve has provided a statistical framework to comprehend the normal progression range relevant to the women in our study. Our labor curve exhibited a smooth, non-linear pattern reminiscent of Zhang\u27s curve, indicating a slower-than-expected labor process. Cervical effacement, fetal head descent, uterine contractions, and labor progression time emerged as crucial predictors for cervical dilation. Cervical effacement serves as an effect modifier for Syntocinon dose, displaying varying degrees of impact on cervical dilation. Nevertheless, it\u27s imperative not to disregard the effects of Syntocinon and epidural analgesia on labor progression
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
