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
ANALISIS KEKERASAN DAN STRUKTUR MIKRO BAJA ST 42 AKIBAT PENGARUH KOMPOSISI ARANG TEMPURUNG KELAPA DAN PUPUK UREA PADA PROSES CARBONITRIDING

Skripsi, Jurusan Teknik Mesin. Fakultas Teknik. Universitas Negeri Malang. Pembimbing: (I) Drs. H. Sunomo.,M.Pd., (II)Rr Poppy Puspitasari, S.Pd., M.T.,Ph.D Kata Kunci: Komposisi media donor, kekerasan, Struktur mikro, baja St 42,packcarbonitriding Packcarbonitriding adalah proses pengerasan permukaan baja dimana baja di panaskan diatas temperature kritis di dalam media donor sehingga terjadi difusi karbon dan nitrogen kedalam permukaan baja. Permasalahannya yang sering timbul yaitu sifat mekanis terutama kekerasan kurang sesuai dengan kebutuhan yang ada.Tujuan dalam penelitian ini adalah untuk mengetahui adanya pengaruh komposisi mediacarbonitriding terhadap kekerasan dan struktur mikro baja St 42. Metode yang digunakan dalam penelitian ini adalah penelitian eksperimental.Dalam penelitian ini yang merupakan variable bebas nya yaitu, arang tempurung kelapadan pupuk urea, sedangkan variable terikat nya merupakan kekerasan dan strukturmikro baja.Analisis dalam penelitian ini menggunakan analisis deskriptif. Hasil penelitian ini menunjukkan adanya pengaruh, dimana ditunjukkan dengan adanya perbedaan kekerasan pada tiap variasi.Pada variasi50%:50% mempunyai kekerasan sebesar 412,4 HV pada titik pertama dan terdapat lebih banyak nitrogen yang masuk dilihat dari jumlah nitrida yang lebih banyak. Sedangkan pada variasi 60%:40% mempunyai kekerasan 263,9 HV terlihat jumlah nitride berkurang dan pada variasi 70%:30% dengan kekerasan 245,6 HV nitrida yang masuk lebih sedikit dan lebih banyak karbida.Penurunan kekerasan ini terjadi karena pengurangan jumlah nitrogen, yang dalam penelitian ini mengurangi prosesnta sepupuk/ammonia yang digunakan pada proses carbonitriding. Dari hasil penilitian ini, perlu diadakan penelitian kembali dengan varia sipresentase komposisi lain dengan lebih banyak prosentase nitrogennya
RITUAL YA QOWIYU: Pergulatan Makna Modernitas, Agama, Budaya Lokal dan Kapitalisme
No full textIn this article, the writer tries to analyze the contrast between modernity, religion, and culture. Shortly, the contrast between religious teaching (Islam) taught by Ki Ageng Gribig, modernity, and culture (Javanese) is shown in the rituals and social-economic life (capitalism spirit) of Jatinom Society, both symbolically and practically. The contrast and meaning relation of the three domains not only result in conflict, tension, and resistance but also relation and new interpretation among the members of society, so that the celebration is held annually. Therefore, the process of interpretation and the different economic, social, cultural, and politic influences will continue from time to time to match with the change experienced by Jatinom society specifically and the population around the area generally. The process of interpretation on religion has changed because of its contrast with the value of modernity. In Jatinom society, the religious process has been formed and influenced by modernity ideas, such as, the process of rationalization on the rituals, that is, the decrease of their belief in ‘blessing’ in apem, but on the other side, they still preserve the rituals to honor their ancestors and customs. They also think that it is economically beneficial because of the visit of thousands of people in the celebration

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
