Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Aplikasi Persamaan Fungsi Kuadrat Dalam Mencari Karakteristik Hubungan Antara Kecepatan Putaran Motor dengan Laju Aliran Air
Get PDFWater Treatment Plant called IPA 1 located on Jl. Penjernihan II No.1 Pejompongan is one of the water installations owned by a water treatment company in DKI Jakarta that operates 24 hours non-stop to produce clean water with a capacity of 2500 liters per second (2500 lps). In a Water Treatment Installation (IPA) there is a process of processing and distributing water, to distribute water needs needed auxiliary equipment that is able to supply clean water as needed. In water supply applications at water treatment plants (IPA), the need for clean water, especially in the capital city of DKI Jakarta, is increasingly increasing, making the pump\u27s performance even greater in its distribution so that it often ignores the amount of energy used in producing and distributing clean water. Testing a distribution pump is needed to determine the working characteristics of a pump. One of the variables tested to determine the pump\u27s working characteristics in terms of electricity is to test the relationship between the motor rotation speed used (RPM) and the flow rate of water generated from the pump (liters / second). It can be seen that if the electric motor used to rotate the pump works in a low rotation, then the electric power used will be low and vice versa. One obstacle that may be faced when we are going to do a test to find out the motor rotation characteristics with the flow rate of water, especially in a water treatment plant in Jakarta is that the distribution of water to the public should not be interrupted when we do the testing, so the data obtained will be difficult to obtain completely, especially when the motor rotates at low speed. One approach that can be taken to look for values that are not measurable is to use polynomial regression. The purpose of this study is to look for variables that cannot be measured at the time of the test, especially the water speed rate variable at each motor rotation change which is regulated by Variable Speed Drive (VSD) on motor pumps number two, three, and four using formula obtained from the coefficients of the polynomial regression method. One formula produced by this polynomial regression is Q = 0.0005 N2 - 0.2231 N - 14.101, with an R2 value of 99.79%, where Q is the water flow rate (liters / second) and N is the motor rotation speed (RPM) ).ABSTRAKInstalasi Pengolahan Air IPA 1 yang berlokasi di Jl. Penjernihan II No.1 Pejompongan merupakan salah satu instalasi air yang dimiliki sebuah perusahaan pengolahan air di DKI Jakarta yang beroperasi selama 24 jam non stop untuk menghasilkan air bersih dengan kapasitas 2500 liter per detik (2500 lps). Pada suatu Instalasi Pengolahan Air ( IPA ) terdapat proses pengolahan dan pendistribusian air, untuk mendistribusikan kebutuhan air dibutuhkan peralatan bantu yang mampu menyuplai air bersih sesuai dengan yang dibutuhkan. Dalam aplikasi penyuplaian air pada instalasi pengolahan air (IPA), kebutuhan air bersih khususnya di daerah ibu kota DKI Jakarta semakin lama semakin meningkat membuat kinerja pompa semakin besar dalam pendistribusiannya sehingga sering mengabaikan besarnya energi yang di pakai dalam menghasilkan dan mendistribusikan air bersih. Pengujian suatu pompa distribusi diperlukan untuk mengetahui karakteristik kerja dari suatu pompa tersebut. Salah satu variable yang diuji untuk mengetahui karakteristik kerja pompa tersebut dalam hal kelistrikannya adalah dengan menguji karakteristik hubungan kecepatan putaran motor yang digunakan ( RPM ) dengan laju aliran air yang dihasilkan dari pompa tersebut ( liter / detik ). Dapat diketahui bahwa apabila motor listrik yang dipakai untuk memutar pompa bekerja dalam putaran yang rendah, maka daya listrik yang dipakai pun akan rendah begitu pula sebaliknya. Salah satu kendala yang mungkin dihadapi pada saat kita akan melakukan pengujian untuk mengetahui karakteristik putaran motor dengan laju aliran air khususnya pada suatu instalasi pengolahan air di Jakarta adalah distribusi air kepada masyarakat tidak boleh terganggu pada saat kita melakukan pengujian, sehingga data yang diperoleh akan sulit didapatkan secara lengkap khususnya pada saat motor berputar pada putaran rendah. Salah satu pendekatan yang dapat dilakukan untuk mencari nilai-nilai yang tidak terukur tersebut adalah dengan menggunakan regresi polynomial. Tujuan dari penelitian ini adalah mencari variable-variabel yang tidak dapat terukur pada saat dilakukannya pengujian, khususnya variabel laju kecepatan air pada setiap perubahan putaran motor yang diatur oleh Variable Speed Drive ( VSD ) pada motor-pompa nomor dua, tiga, dan empat dengan menggunakan rumus yang didapatkan dari koefisien-koefisien metode regresi polynomial. Salah satu rumus yang dihasilkan dengan regresi polynomial ini adalah Q = 0.0005 N2 – 0.2231 N – 14.101, dengan nilai R2 sebesar 99,79 %, dimana variable Q merupakan laju aliran air ( liter / detik ) dan variable N merupakan kecepatan putaran motor ( RPM )
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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.
