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
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
PERLINDUNGAN HAK KESEHATAN REPRODUKSI REMAJA PEREMPUAN DALAM PERKAWINAN DI BAWAH UMUR (STUDI KASUS DI KABUPATEN KATINGAN KALIMANTAN TENGAH)
Full text linkPerkawinan di bawah umur merupakan fenomena yang masih terjadi di kalangan remaja perempuan. Fenomena ini dapat membawa akibat buruk pada perkembangan dan pertumbuhan remaja perempuan, termasuk kesehatan reproduksinya. Secara biologis organ reproduksi remaja perempuan masih dalam proses pematangan, sehingga mereka belum siap untuk melakukan hubungan seks, kehamilan, dan persalinan. Remaja perempuan yang melakukan perkawinan di bawah umur merupakan subjek hukum yang berhak untuk mendapat perlindungan serta jaminan hukum bagi kesehatan reproduksi mereka.
Penelitian ini merupakan penelitian deskriptif analitik dengan pendekatan yuridis sosiologis yaitu bertujuan untuk mengetahui dan menganalisis mengenai perlindungan hukum bagi remaja perempuan yang telah kawin di bawah umur, agar kesehatan reproduksinya tetap terjamin. Penelitian lebih difokuskan pada analisis berbagai peraturan perundang-undangan dan pelaksanaannya di lapangan, serta berbagai faktor yang mempengaruhi perlindungan hak kesehatan reproduksi remaja perempuan tersebut. Penelitian dilakukan di Kabupaten Katingan, Kalimantan Tengah.
Dari hasil penelitian, didapatkan bahwa perlindungan hukum untuk menjamin kesehatan reproduksi remaja perempuan yang telah kawin di bawah umur, secara umum telah diatur dalam peraturan pusat dan daerah. Namun, belum ada peraturan khusus yang mengatur hal ini, sehingga pelaksanaan di lapangan belum maksimal. Adapun faktor-faktor lain yang mendukung perlindungan hak tersebut adalah adanya kesadaran dari masyarakat dan dukungan dari pemerintah daerah. Namun ada pula faktor yang menghambat, yaitu masih ada hal-hal yang mendukung terjadinya perkawinan di bawah umur, seperti pemberian dispensasi dan berlakunya hukum adat, perkawinan siri serta tidak adanya sanksi bagi yang melakukan perkawinan di bawah umu
Analisis Merkuri (Hg) pada Sediaan Bedak Two Way Cake Merk yang tidak Terdaftar dengan Menggunakan ICPS
Full text linkMerkuri (Hg) termasuk logam berat berbahaya, yang dalam konsentrasi kecilpun
bersifat racun. Pemerintah melarang penggunaan merkuri melalui Peraturan Menteri
Kesehatan RI No.445/MENKES/ PER/V/1998. Namun masih saja banyak produsen
yang menggunakan bahan – bahan berbahaya tersebut. Pemakaian merkuri dalam
bedak padat two way cake dapat menimbulkan efek negatif karena merkuri
merupakan zat karsinogenik. Dalam penelitian ini dilakukan uji terhadap bedak padat
two way cake yang tidak terdaftar dan banyak dijual di pasaran dengan harga yang
terjangkau. Penetapan kadar merkuri dalam sampel bedak padat two way cake
dilakukan dengan metode destruksi basah (digesti) dan dianalisis dengan instrumen
ICPS Fisions ARL 3410+. Dari penelitian terhadap tiga sampel bedak padat two way
cake, diperoleh bahwa dua dari tiga sampel bedak ternyata mengandung Hg.
Meskipun kadar Hg yang diperoleh sangat kecil, keberadaan Hg dengan kadar sekecil
apapun tetap dilarang

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
