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
THE COMPARATIVE STUDY BETWEEN THE STUDENTS’ UNDERSTANDING OF MATHEMATICS BY USING ADOBE FLASH CS3 AND IMINDMAP AT THE TOPIC OF THE LIMIT OF FUNCTION (Experimental Study at Science Eleventh Class of SMAN 5 Kota Cirebon)
Get PDFSUDIANTO :
The less variation methods or media in mathematics learning became one of the
things that can affect the low level of students’ understanding of mathematics. Based on
information from some the teachers and students, obtained answer that in the process of
learning mathematics in SMAN 5 Kota Cirebon more incline using conventional method
than utilizing media intensively, especially computer-based media. Students are less
creative just note down manually which tend to be easily forgotten and only optimize
the role of left brain in learning activities.
The aims of the research are (1) To know how is the degree of student's
understanding of mathematics by using Adobe Flash CS3 at the topic of the limit of
function (2) To know how is the degree of student's understanding of mathematics by
using iMindMap at the topic of the limit of function (3) To know the difference between
the students’ understanding of mathematics by using Adobe Flash CS3 and iMindMap
at the topic of the limit of function.
The one alternative of learning media selection that can be used to improve the
mathematics understanding is by using Adobe Flash CS3 and iMindMap in learning.
The using of learning software these iMindMap and Adobe Flash CS3 are expected to
help students and teachers in the process of learning mathematics, especially at the topic
of the limit of function by using mind mapping method and flash animation interactive.
If we use them properly, certainly the learning activities will be more effective and in
accordance with what is to be objectives in education.
The research method used was the experimental method by quantitative
approach. The population in this research was all the students of class XI IPA SMAN 5
Cirebon that consists of four classes XI IPA that was a total of 134 students. While the
sample was taken two classes in random, namely class XI IPA 3 as the first experiment
class by using Adobe Flash CS3 and class XI IPA 4 as the second experiment class by
using iMindMap in learning activities. The technique of collecting data by using test
and observation. The analysis using the prerequisite test which is homogeneity and
normality test, and hypothesis testing using independent sample T-test.
Based on the results of hypothesis testing using independent sample t-test is
known that tcount > ttable , namely 2.277 > 1.998 then Ho is rejected. This showed that
there is significant difference between the students’ understanding of mathematics by
using Adobe Flash CS3 and iMindMap at the topic of the limit of function

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

HUBUNGAN KADAR HEMOGLOBIN DENGAN PROGNOSIS PADA PASIEN STROKE ISKEMIK DI RSUD DR. MOEWARDI
Get PDFABSTRAK
Rut Pamela Sudianto. G0011187. 2015. Hubungan Kadar Hemoglobin dengan Prognosis pada Pasien Stroke Iskemik di RSUD Dr. Moewardi. Skripsi. Fakultas Kedokteran. Universitas Sebelas Maret, Surakarta.
Latar Belakang: Stroke merupakan penyebab kematian kedua di dunia dan diprediksi menjadi penyebab utama kematian dan kecacatan di seluruh dunia pada tahun 2020. Prognosis stroke iskemik sangat tergantung pada perbaikan penumbra di sekitar jaringan infark selama 6 jam pertama. Perbaikan penumbra dilakukan dengan menjaga perfusi jaringan tetap baik, salah satunya ditentukan oleh kadar hemoglobin dalam darah. Penelitian ini bertujuan untuk menganalisis hubungan antara kadar hemoglobin dan prognosis pasien stroke iskemik.
Metode: Penelitian ini menggunakan design penelitian observasional dengan pendekatan studi Kohor retrospektif. Sampel diambil dari 30 pasien stroke iskemik di Bangsal dan Poliklinik RSUD Dr. Moewardi dengan teknik fixed exposure sampling. Instrumen yang digunakan adalah National Institute of Health Scale (NIHSS) dan rekam medik. Uji statistik yang digunakan adalah analisis regresi cox
Hasil: Empat dari 22 pasien (18.2%) dengan kadar Hb normal mengalami prognosis buruk Tiga dari 8 pasien (37.5%) dengan kadar Hb abnormal mengalami prognosis buruk. 3 dari 15 pasien (20%) dengan usia < 61 tahun mengalami prognosis buruk dan 4 dari 15 (26.7%) pasien dengan usia ≥ 61 tahun mengalami prognosis buruk.
Simpulan: Pasien stroke iskemik dengan kadar hemoglobin abnormal berisiko 0.51 kali lebih rendah untuk memiliki prognosis buruk daripada pasien stroke iskemik dengan kadar hemoglobin normal, walaupun secara statistik tidak signifikan (HR = 0.51; CI = 95% 0.11 s.d. 2.28; p = 0.377).

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
