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
Isomerisasi Enzimatik Tepung Sorgum Merah Untuk Pembuatan “High Fructose Syrup”
Full text linkSorgum merupakan tanaman serealia yang mempunyai produktivitas bersar di Indonesis (4,24 – 6,17 ton/ha). Di Jawa Timur produktivitas sorgum mencapai 1,76 ton/ha. Pemanfaatan sorgum sebagian besar diolah menjadi tepung sorgum, akan tetapi tepung sorgum memiliki beberapa kekurangan seperti masih adanya kandungan asam fitat dan tanin didalam tepung sorgum dimana kandungan bahan ini tidak baik untuk kesehatan, selain itu kandungan gluten dalam tepung sorgum tidak sebaik tepung gandum. Untuk mengoptimalkan peran tepung sorgum yaitu menjadikan tepung sorgum sebagai bahan baku pembuatan high fructose syrup, mengingat kandungan pati didalam tepung sorgum cukup tinggi yaitu mencapai 70% sehingga berpotensi untuk dikonversi menjadi high fructose syrup. HFS merupakan salah satu gula cair yang banyak digunakan dalam industri makanan dan minuman, penggunaan HFS dikarenakan HFS mempunyai tingkat kemanisan yang tinggi, tidak mudah mengkristal, dan mudah larut dalam air. Pada penelitian ini pembuatan high fructose syrup dilakukan dengan cara hidrolisa enzimatis menggunakan α-amilase, glukoamilase, dan glukoisomerase. Kondisi operasi optimal proses likuifikasi pada suhu 95 oC, pH 7 dan waktu reaksi 150 menit, pada proses sakarifikasi kondisi optimal pada suhu 60 oC, pH 5, dan waktu operasi 48 jam dengan konsentrasi gula reduksi 197,358 g/l dan yield 98,679%, sedangkan proses isomerisasi kondisi optimal pada pH 8, jumlah enzim 500 mg, dan waktu operasi 48 jam dengan konsentrasi fruktosa sebesar 29,80 g/100 ml (metode resorcinol), dan 17,47775 %b/v (HPLC). Akan tetapi jika dilihat dari produktivitasnya kondisi optimal dari proses sakarifikasi yaitu pada pH 8, jumlah enzim 500 mg dan waktu reaksi 24 jam, hal ini dikarenakan pada waktu ke 24 jam dapat menghasilkan kandungan sirup fruktosa yang hampir sama dengan waktu 48 jam. Analisa statistik menggunakan metode two-way anova general linier model menghasilkan nilai p value 90%, sehingga dapat dikatakan bahwa variabel yang digunakan pada ketiga step proses hidrolisa memberikan pengaruh yang signifikan terhadap produk yang dihasilkan.

Sorghum is a cerealia crop that has high productivity in Indonesis (4,24 - 6,17 ton / ha). In East Java the productivity of sorghum reached 1.76 tons / ha. Utilization of sorghum is mostly processed into sorghum flour, but sorghum flour has some deficiencies such as the presence of phytic acid and tannin in sorghum flour where the ingredients are not good for health, besides the gluten content in sorghum flour is not as good as wheat flour. To optimize the role of sorghum flour is to make sorghum flour as a raw material for making high fructose syrup, considering the starch content in sorghum flour was high, reaching 70% , it has the potential to be converted into high fructose syrup. HFS is one of the most widely used liquid sugar in the food and beverage industry, many industry using HFS because it has high level of sweetness, not easy to crystallize nature, and more soluble in water. In this study, high fructose syrup was made by enzymatic hydrolysis using α-amylase, glucoamylase, and glucoisomerase. The optimum operating conditions of the liquefaction process at 95 ° C, pH 7 and reaction time of 150 minutes, in the saccharification process ,optimum condition at 60 ° C, pH 5, and operating time 48 hours with the reduction sugar concentration of 197.358 g / l and yield 98.679%. Optimum conditions of Isomerization process at pH 8, enzyme 500 mg, and 48 hours operating time with fructose concentration of 29.80 g / 100 ml (resorcinol method), and 17.47775% w / v (HPLC). However, if viewed from the productivity of optimal conditions of the saccharification process is at pH 8, the amount of enzyme 500 mg and reaction time 24 hours, this is because at the time to 24 hours can produce fructose syrup content is almost equal to 48 hours. Statistical analysis using two-way anova general linear model resulted in p value 90%, so it can be said that the variables used in the three step of hydrolysis process give significant effect to the product result
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.
