Going Beyond Counting First Authors in Author Co-citation Analysis
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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

Analisis Coal Plugging Atau Penyumbatan Batu Bara Pada Mesin Coal Feeder Unit 1-4 Dengan Metode FTA (Fault Tree Analysis) Di PT. ABZ
PT. ABZ is one of the big companies that runs its main business in the field of power generation in Indonesia. The company is experiencing problems in one of its equipment, namely coal feeder units 1-4 which often occurs coal plugging or coal blockage. Coal feeder is one of the main equipment that serves to regulate the amount of coal entering the pulverizer. This study aims to determine the root cause of problems from coal plugging or coal obstruction in coal feeder equipment at PT. ABZ using the FTA (Fault Tree Analysis) Method and provides a proposed improvement with the 5W + 1 H Method (what, why, who, when, where and how). Based on the analysis using FTA, it was found that the cause of coal plugging or blockage that occurs in coal feeder machines is due to contamination of the coal used, low calorific value of coal, the machine operates continuously, the machine is old, lack of control from the workers and coal wet when you want to use. Proposed improvements have been made and one of them is by separating wet coal from dry coal automatically using a coal online analyzer. PT. ABZ merupakan salah satu perusahaan besar yang menjalankan bisnis utamanya dibidang pembangkit tenaga listrik di Indonesia. Perusahaan ini mengalami permasalahan di salah satu peralatannya yaitu coal feeder unit 1-4 yang sering terjadi coal plugging atau penyumbatan batubara. Coal feeder merupakan salah satu peralatan utama yang berfungsi untuk mengatur jumlah batubara yang masuk ke pulverizer. Penelitian ini bertujuan untuk mengetahui akar penyebab masalah dari gangguan coal plugging atau peyumbatan batubara  di peralatan coal feeder di PT. ABZ dengan menggunakan Metode FTA (Fault Tree Analysis) dan memberikan usulan perbaikan dengan Metode 5W + 1 H (what, why, who, when, where dan how). Berdasarkan analisa menggunakan FTA, didapatkan bahwa penyebab coal plugging atau penyumbatan yang terjadi pada mesin coal feeder adalah dikarenakan adanya kontaminasi pada batubara yang digunakan, nilai kalori batubara yang rendah, mesin beroperasi secara terus menerus, mesin sudah tua, kurangnya kontrol dari pihak pekerja dan batubara basah saat akan digunakan. Usulan perbaikan telah dibuat dan salah satunya adalah dengan cara memisahkan batubara basah dengan batubara yang kering secara otomatis menggunakan alat coal online analyzer. Â
Analisis Postur Pekerja Pengelasan Di CV. XYZ dengan Metode Rapid Entire Body Assessment (REBA)
CV. XYZ is one of the welding workshops that serves the manufacture of iron products with 4 (four) welding workers. Welding work carries risks for experiencing Musculoskeletal Disorders (MSDs) for the welding worker. This can be caused by work posture factors that often bend and squat when doing welding. Based on the calculation results, REBA score results obtained with action level 3 (three) which states that the welding work in the CV. XYZ is at a high level of risk so immediate corrective action is needed by CV. XYZ Proposed improvement of the worker\u27s posture when welding work is a redesign of the work station or the addition of work aids based on ergonomic principles such as the procurement of a work table for the welding work process so as to reduce the risk of workers\u27 posture to a low risk level. CV. XYZ  merupakan salah satu bengkel pengelasan yang melayani pembuatan produk besi dengan 4 (empat) orang pekerja pengelasan. Pekerjaan pengelasan memiliki risiko untuk mengalami Musculoskeletal Disorders (MSDs) bagi pekerja pengelasan tersebut. Hal ini dapat disebabkan oleh faktor postur kerja yang sering membungkuk dan jongkok saat melakukan pengelasan. Berdasarkan hasil perhitungan, didapatkan hasil skor REBA dengan action level 3 (tiga) yang menyatakan bahwa pekerjaan pengelasan di CV. XYZ berada pada level risiko tinggi sehingga diperlukan tindakan perbaikan secepatnya oleh CV. XYZ. Usulan perbaikan postur tubuh pekerja saat pekerjaan pengelasan adalah perancangan ulang stasiun kerja atau penambahan alat bantu kerja berdasarkan prinsip-prinsip ergonomi seperti pengadaan meja kerja untuk proses pekerjaan pengelasan sehingga dapat mengurangi risiko postur tubuh pekerja menjadi level risiko rendah. Â
