Full text linkReal Analysis is the subjects to help the students in critical thought. Students must have the definitions and theorems to solve the problems and perform a process which is often called the preliminary analysis. After that, students construct the proof based on the preliminary analysis. Based on the characteristics of the problem in Real Analysis, the solution given to the problem is using flow proof in composing preliminary analysis The research shows that the student's ability in analyzing can be improved by using flow proo
KORELASI KADAR OSTEOKALSIN DENGAN GLUKOSA PUASA PADA DIABETES MELITUS TIPE 2
Full text linkLatar Belakang: Diabetes melitus (DM) merupakan masalah kesehatan masyarakat yang meningkat sangat cepat. Diabetes melitus berpengaruh kepada jaringan tulang secara primer sehingga mengubah kualitas tulang, mengakibatkan peningkatan fragilitas tulang dan risiko fraktur. Osteokalsin dibentuk oleh osteoblas, berperan dalam homeostasis glukosa, diregulasi oleh undercarboxylated osteocalcin (ucOC). Hubungan tulang dengan metabolisme glukosa telah ditemukan pada dekade terakhir. Penelitian ini bertujuan membuktikan korelasi kadar osteokalsin dengan glukosa puasa pasien DM tipe 2. Metode: Penelitian ini merupakan penelitian analitik dengan rancangan potong lintang terhadap 21 orang pasien DM tipe 2 yang melakukan pemeriksaan darah di Laboratorium Sentral RSUP Dr. M. Djamil Padang. Penelitian dilakukan mulai bulan Oktober 2017 sampai Oktober 2018. Kadar osteokalsin diperiksa dengan metode electrochemiluminescence immunoassay (ECLIA) dan kadar glukosa puasa diperiksa dengan metode enzimatik heksokinase. Analisis statistik menggunakan uji Spearman. Hasil uji statistik dianggap bermakna jika p<0,05.
Hasil: Subjek penelitian sebanyak 21 orang laki-laki pasien DM tipe 2. Rentang usia berkisar antara 40-76 tahun. Rerata kadar osteokalsin dan glukosa puasa berturut-turut pada DM tipe 2 adalah 16,89 (7,64) ng/mL dan 175,33 (46,84) mg/dL. Uji korelasi Spearman menunjukkan korelasi negatif lemah tidak bermakna antara osteokalsin dengan glukosa puasa pada DM tipe 2 (r= -0,343 ; p>0,05).
Simpulan: Terdapat korelasi negatif lemah antara osteokalsin dengan glukosa puasa pada DM tipe 2.
Kata kunci: osteokalsin, glukosa puasa, diabetes melitus tipe

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
FAKTOR-FAKTOR YANG MEMPENGARUHI HASIL BELAJAR MATEMATIKA SISWA UNTUK PENERAPAN BAHAN AJAR KONTEKSTUAL MENGINTEGRASIKAN PENGETAHUAN TERKAIT DAN REALISTIK
Full text linkMathematics learning on high school should be associated with other sciences and everyday life. In this way, the mathematics learning is more realistic, interesting and meaningful. However, re-ality shows that mathematics learning materials has not been associated with other sciences and eve-ryday life. Initial research find that needs to be develop contextual mathematics material. Before the learning materials are prepared, it is important to know the characteristics of learners in following the learning of mathematics that affect the learning outcomes. There are five factors that influence the learning outcomes, namely background, interest, attitude, motivation and learning styles The purpose of research is to determine the factors that influence learning outcomes. Type of this research is de-scriptive research. The instruments are assessment sheets for learners characteristics and test. The results is factors that influence the learning outcomes of learners directly for the development needs of contextual mathematics teaching materials to integrate related knowledge and realistic approach is the learning style
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
