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
Analisis Status Pencemaran Air dengan Gastropoda Sebagai Bioindikator di Pantai Pandaratan Desa Jaring Halus Kabupaten Langkat Sumatera Utara
No full textJaring Halus is a coastal village located in Secanggang District, Langkat Regency. At this location there is a mangrove ecosystem that is near and bordered by residential and marine settlements. However, Pandaratan Beach is currently experiencing dirty environmental conditions, allegedly due to the inclusion of waste into water bodies which if left unchecked will cause pollution on the beach. Gastropods as organisms that live in waters are very sensitive to changes in the quality of the water in which they live. Declining water quality will reduce the wealth of natural resources of these waters. This study aims to determine the condition of the waters and Gastropod diversity in Pandaratan Beach, Jaring Halus V, which is seen based on the ABC curve and the Storet Index. This research was conducted in May - June 2019 using a purposive sampling method which was divided into 3 stations. The results showed that the Diversity Index (H ') ranged from 1.69 to 1.96, the uniformity index (E) ranged from 0.73 to 0,78 and the dominance index value from (C) ranged from 0.18 to 0.26 . And according to PP No. 82 of 2001 concerning Management of Water Quality and Water Pollution Control, and by using the Storet Index states that the condition of the Pandaratan Coastal Waters of the Jaring the "medium" category with the density curve and the biomass overlapping each other.Desa Jaring Halus merupakan desa pesisir yang terletak di Kecamatan Secanggang, Kabupaten Langkat. pada lokasi ini terdapat ekosistem mangrove yang berada dekat dan berbatasan dengan pemukiman warga dan laut. Namun saat ini Pantai Pandaratan mengalami kondisi lingkungan yang kotor diduga karena masuknya limbah kedalam badan perairan yang jika dibiarkan maka akan menyebabkan pencemaran di Pantai tersebut. Gastropoda sebagai organisme yang hidup di perairan sangat peka terhadap perubahan kualitas air tempat hidupnya. Penurunan kualitas air akan menurunkan kekayaan sumber daya alam perairan tersebut. Penelitian ini bertujuan untuk mengetahui kondisi perairan dan keanekaragaman Gastropoda di Pantai Pandaratan Desa Jaring Halus yang dilihat berdasarkan kurva ABC dan Indeks Storet. Penelitian ini dilaksanakan pada bulan Mei – Juni 2019 menggunakan metode purposive sampling yang dibagi menjadi 3 stasiun. Hasil penelitian menunjukkan bahwa nilai Indeks Keanekaragaman (H’) berkisar 1,69 – 1,96 , nilai indeks keseragaman (E) berkisar 0,73-0,78 dan nilai indeks dominansi berkisar (C) berkisar 0,18-0,26. Dan menurut PP No. 82 Tahun 2001 Tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air, dan dengan menggunakan Indeks Storet menyatakan bahwa kondisi Perairan Pantai Pandaratan Desa Jaring Halus dinyatakan tercemar dalam kategori “sedang” dan berdasarkan kurva ABC (Abundance and Biomass Comparison) menyatakan bahwa kondisi perairan dinyatakan tercemar dalam kategori “sedang” dengan kurva kepadatan dan biomassa yang saling tumpang tindih.95 HalamanSkripsi Sarjan
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
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.
