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

RISMAYANI ARMIN, 2015. Analisis Kesalahan Siswa dalam menyelesaikan soal- soal operasi hitung bilangan bulat ditinjau dari gaya kognitif siswa kelas IV SD Negeri 2 Batulo Kecamatan Wolio Kota Baubau (Dibimbing oleh Ilham Minggi dan Asdar).
Konsep dalam pembelajaran matematika merupakan unsur mendasar yang harus dipahami oleh siswa. Selain konsep, langkah-langkah dan operasi dalam pembelajaran matematika juga sangat penting untuk dipahami. Dengan langkah-langkah serta operasi dalam matematika maka akan memudahkan siswa dalam menggunakan simbol-simbol matematika dan menyusun langkah-langkah dalam menyelesaikan soal.
Tujuan penelitian ini adalah (i) Kesalahan-kesalahan apa yang dominan dilakukan oleh siswa kelas IV SD Negeri 2 Batulo Kecamatan Wolio Kota Baubau dalam menyelesaikan soal-soal operasi hitung bilangan bulat ditinjau dari gaya kognitifnya; dan (ii) Faktor-faktor dominan apa yang menyebabkan siswa melakukan kesalahan dalam menyelesaikan soal-soal operasi hitung bilangan bulat dikelas IV SD Negeri 2 Batulo kecamatan Wolio kota Baubau ditinjau dari Gaya Kognitifnya. Penelitian ini dikategorikan ke dalam penelitian deskriptif dengan pendekatan kualitatif. Teknik pengumpulan data melalui pemberian tes diagnostik dan wawancara. Subjek penelitian terdiri dari empat orang, dua subyek gaya kognitif tinggi Field Independent (FI) dan dua subyek gaya kognitif Field dependent (FD) berdasarkan hasil Tes GEFT.
Hasil penelitian menunjukkan bahwa (i) kesalahan konsep, prinsip dan operasinya cenderung terjadi pada subjek yaitu kelompok FD tidak menyebutkan atau menuliskan syarat untuk menyelesaikan soal. Kesalahan konsep, prinsip serta operasinya yaitu kurang tepat dalam mengidentifikasi unsur-unsur dalam bilangan bulat terutama penempatan simbol, langkah-langkah dan nilai tempat penyelesaian dan kurang tepat dalam memaparkan langkah penyelesaian secara sistematis. Kesalahan prinsip dan operasi terjadi pada subjek yakni kelompok FI yaitu kurang tepat dalam menjelaskan langkah-langkahnya, kesalahan yang lain adalah kurang tepat dalam perhitungan untuk subjek FI yaitu keteraturan langkah-langkah dalam menyelesaikan soal; (ii) penyebab terjadinya kesalahan konsep antara lain adalah tidak mengerti dengan syarat-syarat untuk menyelesaikan soal, sulit memahami simbol, bahkan tanda negatif dalam menyelesaikan langkah penyelesaian, siswa lebih cenderung mengingat daripada memahami, kurang memahami langkah-langkah operasi perkalian, dan sering melupakan materi pelajaran yang sudah lewat. Penyebab terjadinya kesalahan prinsip antara lain adalah tidak mengerti operasi kadang salah langkah pengerjaan atau memutarbalikkan tanda arah dan tanda operasinya, kesulitan terhadap simbol-simbol,siswa merasa bingung dalam memecahkan soal terkadang memiliki penyelesaian ‘terbalik-balik’,dan siswa masih merasa bingung jika menemui perhitungan yang melibatkan tanda positif (+) dan negatif (-).
ABSTRACT
RISMAYANI ARMIN. 2015. Analysis of Students Errors in Answering the Questions of interger Arithmetic Operations on Cognitif Style of Class IV Students at SDN 2 Batulo in Wolio Subdistrict of Baubau (Supervised by Ilham Minggi and Asdar).
Concept in mathematics learning is the basic element which should be understood students. Other than concept, step oeration in Mathematicslearning in essential to be comprehended as well. The steps and operations will assist students in using Mathematics symbol an arranging steps in answering the questions.
The study aims at examining (i) the dominant errors conducted by class IV students at SDN 2 Batulo in Wolio Subdistrict of Baubau (ii) the dominant factors causes the students error in answering the questions of interger arithmetic operations in class IV at SDN 2 Batulo in Wolio subdistrict of Baubau based on cognitive style. The study is categorized as descriptive qualitative approach. Data is collected through diagnostic test and interview. The subjects of the study are four people consist of two subjects with field Independent (FI) cognitive style of and two subjects of field dependent (FD) cognitive style based on the result og GEFT test.
The results of the study reveal that (i) the errors in concept, principle, and operations tend to be conducted by the FD subjects by not stating or writing the requirement to answer the questions. The aforementioned errors are inappropriate in identifying the elements in integers, particularly the placement of symbols, steps and score of placement and inappropriate in describing systematic answering steps. The errors in principle and operation conducted by FI subjects which is inappropriate in describing the steps and inappropriate in counting on regularity steps in answering the questions, (ii) the causes of errors in concepts among others are incomprehension of requirement to answer and question, problems in comprehending symbol, negative symbol in solving problems, students tend to memorize than comprehend it, lack of understanding of steps of multiplication operation, and forget the previous learning material. The causes of errors in principle among others are incomprehension of operation, misstep in working on the questions or twist direction sign and operation sign, problem symbols, students are confused in solving questions of integer arithmetic operations, and students are confused when the question involves positive (+) and negative (-) sign
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.
