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
Identifikasi dan Kelimpahan Plankton di Tambak Udang Vannamei (Litopenaeus vannamei) Sistem Intensif di CV. Lautan Sumber Rejeki Banyuwangi Jawa Timur
Full text linkTambak di Indonesia terutama di Kabupaten Banyuwangi biasanya menghasilkan produk perikanan yang memiliki nilai ekonomis tinggi berorientasi ekspor. Salah satu produk perikanan yang sedang berkembang saat ini adalah udang vanname (Litopenaeus vannamei). Pengembangan system budidaya udang vanname menggunakan system intensif selain memperhatikan pakan, keberadaan plankton juga merupakan salah satu factor penting dalam budidaya udang sebagai tropic level dalam perairan di mana fitoplankton menjadi produsen utama atau tropic level pertama di perairan. Sifat plankton dalam perairan bisa menguntungkan dan atau merugikan. Kondisi fisika, kimia, dan biologi suatu perairan juga akan memengaruhi distribusi plankton di perairan secara langsung akan berpengaruh pada kelimpahan plankton. Kualitas air pada budidaya udang vanname ini dikelola dengan memanfaatkan aplikasi probiotik dan penumbuhan plankton. Tujuan dari penelitian ini adalah untuk memperkirakan kelimpahan dan stabilitas air tambak dari pengukuran biologis (variasi, keragaman, dan dominasi plankton) di tambak udang CV. Lautan Sumber Rejeki Banyuwangi. Metode analisis data yang digunakan yaitu kuantitatif secara deskriptif. Adapun parameter uji pada penelitian ini yaitu kelimpahan plankton, keanekaragaman plankton, keseragaman plankton, dan dominasi jenis plankton yang terdapat pada tambak udang vanname. Hasil identifikasi plankton pada tambak udang vanname di CV. Lautan Sumber Rejeki Banyuwangi ditemukan 4 jenis plankton diantaranya yaitu : (33,3 – 39)% dari golongan Chlorophyta (Green Algae), (5 – 12)% dari golongan Cyanophyta (Blue-Green Algae), (32 – 34)% dari golongan Bacillariophyta (Diatoms), (7,2 – 9)% dari golongan Phyrrophyta (Dinoflagellata), dan 7% dari golongan Protozoa. Status indeks keanekaragaman (H’) sedang, indeks keseragaman (E) tinggi dan indeks dominasi rendah.Tambak di Indonesia, khususnya di Kabupaten Banyuwangi, umumnya menghasilkan produk perikanan dengan nilai ekonomi tinggi yang ditujukan untuk ekspor. Salah satu produk perikanan yang sedang berkembang adalah udang vannamei ( Litopenaeus vannamei ). Pengembangan budidaya udang vannamei menggunakan sistem intensif dengan memperhatikan pakan dan keberadaan plankton sebagai faktor penting dalam ekosistem perairan, di mana fitoplankton berfungsi sebagai produsen utama atau tingkat trofik pertama. Keberadaan plankton dapat memberikan dampak yang menguntungkan maupun merugikan, dan persebarannya dipengaruhi oleh kondisi fisik, kimia, dan biologi perairan, yang pada gilirannya mempengaruhi buruknya plankton. Kualitas udara dalam budidaya udang vannamei dikelola dengan menggunakan aplikasi probiotik dan upaya untuk menumbuhkan plankton.

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
PENCEGAHAN PENYAKIT PADA BUDIDAYA UDANG VANNAMEI (Litopenaeus vannamei) DI CV. AGRABINTA SHRIMP FARM DESA SINARLAUT KABUPATEN CIANJUR PROVINSI JAWA BARAT
Full text linkDisease attacks are an important issue that should not be ignored as they relate to successful cultivation. Attacks can cause deaths and delays in the production process. To address this problem, disease prevention must be improved to reduce risk factors for production failure. Disease prevention in CV. Agrabinta Shrimp Farm includes prevention through the cultivation preparation stage, prevention through the selection and distribution of fry, prevention through the maintenance process, and prevention through water quality management and finally prevention through the implementation of biosecurity. This research was conducted for one month starting from January to February 2025. The fry used in this study are in plot 2 using PLB (Prima Larvae Bali) and plot 6 using STP fry (Suri Tani Pemuka) which is stocked in PL 10. The data taken from this study are prevention through cultivation preparation, selection and distribution of fry, maintenance, water quality management, and the application of biosecurity. It can be concluded that the implementation of biosecurity in CV. Agrabinta Shrimp Farm is good enough to keep shrimp from diseases and viruses that attack because both plots are still good and can survive until this research is completed. In plot 2, the growth is faster than in plot 6, this can also be seen from the sampling of Average Daily Growth (ADG) and Average Body Weight (ABW) which are always increasing, indicating that shrimp grow healthy because they are not affected by diseases or viruses
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
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
