    The 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

    “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

    HUBUNGAN PELAKSANAAN MENYUSUI DINI DENGAN PEMBERIAN ASI EKSKLUSIF DIWILAYAH KERJA PUSKESMAS TANAH GARAM KOTA SOLOK

    Pemberian ASI eksklusif secara umum menurun dibeberapa daerah di Sumatra Barat pada tahun 2008, tetapi di Kota Solok terjadi peningkatan pemberian ASI eksklusif. Untuk mengetahui salah satu penyebab meningkatnya pemberianASI eksklusif di Kota Solok maka dilakukan penelitian tentang hubungan pelaksanaan menyusudini denganASI eksklusif di wilayah kerja Puskesmas Tanah Garam Kota Solok Tahun 2010. Penelitian ini menggunakan desain case control, pengambilan sampel secara purposif. Data dikumpulkan dengan menggunakan kuesioner. Pengumpulan data dimulai Bulan Maret sampai dengan Mei 2010 dengan jumlah responden 1 89 orang (110 responden sebagai kasus dan 79 responden sebagai control). Data diolah secara komputerisasi dengan menggunakananalisa univariat dan bivariat. Hasil penelitian didapatkan dari 110 responden yang memberikan ASI eksklusif 5,8% responden melaksanakan inisiasi menyusu dini dan 52,4% responden tidak melaksanakan inisiasi menyusu dini. Responden yang tidak memberikanASI eksklusif 79 orang, 40,7% responden melaksanakan inisiasi menyusu dini dan 1,1% responden tidak melaksanakan inisiasi menyusu dini. Setelah dilakukan uji statistik terdapat hubungan yang signifikan (p= 0,045) antara inisiasi menyusui dini dengan pemberian ASI Eksklusif. Pelaksanaan inisiasi menyusui dini 4,3 kali akan berhasil memberikan ASI eksklusif bila dibandingkan dengan tidak melaksanakan inisiasi menyusudini. Berdasarkan hasil penelitian dapat disimpulkan bahwa sebagian besar responden tidak melaksanakan inisiasi menyusu dini, namun dari sebagian kecil yang melaksanakan inisiasi menyusui dini, sebahagian besar responden memberikanASI Eksklusif

    AbstrakSinar ultra violet (UV) selain mempunyai dampak positif terhadap kesehatan, UV juga dapat membahayakan kesehatan. Dampak negatif UV ini dirasakan oleh orang-orang yang terpapar sinar UV dalam jangka waktu lama, seperti nelayan dan petani. Radiasi UV tingkat sedang menyebabkan kulit kemerahan (eritema), sedangkan tingkat tinggi dapat menyebabkan perdarahan pada kulit.Penelitian ini bertujuan untuk mengetahui efek pemberian vitamin E terhadap jumlah erytrosit dan aktifitas enzim katalase tikus akibat paparan sinar ultra violet. Penelitian ini bersifat eksperimental dengan menggunakan tikus sebagai hewan coba, yang dilakukan di Laboratorium Biokimia Fakultas Kedokteran Universitas Andalas dari bulan September – Desember 2008. Populasi adalah 20 ekor tikus galur Wistar, umur ± 2 bulan dan berat badan 200-250 gram. Sampel diambil secara acak (simple random sampling) dari populasi dan dibagi menjadi dua kelompok yaitu : Kelompok kontrol (Kelompok yang diradiasi UV 6 jam/hari selama 3 minggu tanpa pemberian vitamin E) dan kelompok perlakuan (Kelompok yang diradiasi UV 6 jam/hari selama 3 minggu dengan pemberian vitamin E dosis 0.45 IU/kg BB/1 kali/hari). Hasil penelitian menunjukkan pada kelompok kontrol terjadi penurunan jumlah erytrosit dan aktifitas enzim katalase akibat paparan sinar UV. Jumlah Penurunan ini akan lebih sedikit setelah pemberian vitamin E.Efek pemberian vitamin E dapat menghambat penurunan jumlah erytrosit dan aktivitas enzim katalase tikus yang terpapar sinar ultraviolet.Kata Kunci : VitaminE, Erytrosit, KatalaseAbstract Ultraviolet (UV) in addition to having a positive impact on health, UV can also endanger your health. UV negative impact is felt by the people who are exposed to UV light for long periods, such as fishermen and farmers. UV radiation levels are causing skin redness (erythema), whereas high levels can cause bleeding in the skin. This study aims to determine the effect. These are experimental studies using rats as an animal, which conducted the Biochemistry Laboratory of the Faculty ofARTIKEL PENELITIAN128Medicine University of Newcastle from September - December 2008. Population is 20 strains of Wistar rats, age ± 2 months and weight 200-250 grams. Samples taken at random (simple random sampling) of the population and divided into two groups: control group (group UV irradiated 6 hours/day for 3 weeks without vitamin E) and the treatment group (group UV irradiated 6 hours/day for 3 weeks with doses of vitamin E 0:45 IU/kg BB/1 kali/day). The results showed in the control group declines erytrosit and catalase enzyme activity due to exposure to UV. decline was much less after vitamin E. Conclusion: The effect vitamin E can inhibit the decrease in the number erytrosit and catalase enzyme activities of rats exposed to ultraviolet light.of vitamin E on the number of erytrosit and catalase enzyme activities of rats by exposure to ultraviolet light.Key words : Vitamin E, Erytrosit, Katalase</p

    Appropriate Similarity Measures for Author Cocitation Analysis

    We 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

    We 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

    We 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
