Get PDFRASIO ESTRIOL/ ESTRADIOL TINGGI SEBAGAI PREDIKTORKEBERHASILAN INDUKSI PERSALINAN PADA KEHAMILANLEWAT WAKTUMuhammad Nur Adintyo Rahman1, Shinta Prawitasari2, Heru Pradjatmo3ABSTRACTBackground: Induction of labor is a common procedure performed at 15-20 % of pregnancies. The mostcommon indication was prolonged pregnancy (70 %). The past decade labor induction rate was increased2-fold as well as the risk of cesarean section. Difficulties to predict the success of induction made predictorsof success of induction widely studied. Predictors can be physical or chemical markers. One of the chemicalmarker is the ratio of estriol to estradiol levels.Objective: To determine the value of the ratio of estriol/ estradiol to predict success of induction of laborin prolonged pregnancy.Method: The design of study are Prospective Cohort. Study two hospitals (Wonosobo District Hospitaland Banjarnegara District Hospital) used in this study from September 10, 2013 until December 31,2013. Blood sampling was drown from the subject before induction to examin the levels of estriol andestradiol the induction which end in vaginal delivery were noted as succesull induction Receiver OperatingCharacteristic (ROC) method in order to determine the sensitivity, specificity, positive predictive value,negative predictive value and Area Under the Curve. Bivariate and multivariate analyzes also used todetermine the correlation between variables.Results and Discussion: This study obtained 76 samples, 69 with successful induction and 7 failed ofinduction. The research got a cut-off was point 35 the sensitivity was 71% value, specificity value of 71%,positive predictive value 49%, negative predictive value was 55.6%. Area Under the was value of 80,7%.Positive likelihood ratio 1,06 and negative likelihood ratio 0,88. Bivariate and multivariate analysis showedthat the ratio of estriol / estradiol ≥ 35 ng / mL significantly associated with successful induction (OR 9,598;95% CI 1,378-66,859) Bishop score was also associated with a significant induction success (OR 13,481;95% CI 1,955 -92,955)Conclusion: This study shows that the proportion ratio of estriol / estradiol in succeed induction groupwere higher (≥ 35) compared with induction failure group (<35).Keywords: prolonged pregnancy, labor induction , estriol/ estradiol ratio, predictorsABSTRAKLatar Belakang: Induksi persalinan adalah prosedur umum yang dilakukan pada 15-20% kehamilan.Indikasi tersering adalah kehamilan lewat waktu (70%). Satu dekade terakhir angka induksi persalinantelah meningkat 2 kali lipat begitu juga dengan risiko seksio sesarea. Keberhasilan induksi sulit diprediksi.Prediktor keberhasilan induksi banyak diteliti baik penanda fisik maupun kimia. Salah satu penanda kimiaadalah rasio kadar estriol terhadap estradiol.Tujuan: Mengetahui nilai rasio kadar estriol estradiol untuk memprediksi keberhasilan induksi padakehamilan lewat waktuMetode: Kohort prospektif.

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
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.
