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
Analisa Dampak Lingkungan Dari Proses Daur Ulang Plastik Dengan Pendekatan Life Cycle Assessment
Get PDFPlastik sudah menjadi kebutuhan masyarakat dalam kehidupan sehari-hari. Produk yang dihasilkan oleh industri sebagian besar dikemas dengan bahan plastik. Penggunaan plastik yang semakin marak, membawa dampak negatif bagi lingkungan hidup. Tujuan dari penelitian ini adalah untuk menilai dampak lingkungan yang dapat timbul selama proses produksi biji plastik daur ulang jenis polyethylene sebanyak 2,5 ton di pabrik biji plastik CV Saam Jaya. Dengan melakukan penilaian dampak lingkungan akan memberikan evaluasi serta rekomendasi yang dapat dilakukan oleh pabrik biji plastik CV Saam Jaya untuk mengurangi potensi timbulnya dampak lingkungan yang disebabkan siklus hidup daur ulang biji plastik.
Pada penelitian ini menggunakan pendekatan life cycle assessment untuk menilai dampak lingkungan yang timbul sepanjang siklus hidup biji plastik dari proses transportasi bahan baku, proses pemanasan, proses pendinginan, proses pemotongan, proses packaging, dan proses distribusi produk jadi. Terdapat 4 tahap pada metode LCA menurut standar ISO 14040:2006 yaitu tahap goal and scope yaitu menentukan tujuan dan cakupan LCA, tahap life cycle inventory yaitu melakukan pengumpulan dan pengukuran data, tahap life cycle impact assessment melakukan perhitungan nilai dampak lingkungan menggunakan metode EDIP 2003 dan dibantu software SimaPro 8 untuk melakukan perhitungan, dan yang terakhir tahap interpretasi hasil.
Hasil dari penelitian menunjukkan bahwa proses distribusi produk jadi dengan nilai dampak terbesar 13,4 Pt atau 56,8% dari total nilai dampak pada keseluruhan proses sebesar 23,19 Pt, proses dengan nilai dampak terbesar selanjutnya adalah proses pemanasan dengan nilai 7,25 Pt (30,7%), proses transportasi bahan baku sebesar 1,33 Pt (5,7%), proses pendinginan sebesar 0,96 Pt (4%), proses pemotongan sebesar 0,193 Pt (0,8%), proses packaging 0,0642 Pt (0,2%). Selanjutnya dampak terbesar yang timbul dari hasil pengukuran siklus hidup biji plastik adalah ozone depletion atau penipisan lapisan ozon yang menyebabkan sinar ultra violet lebih banyak menembus atmosfer bumi. Dampak ozone depletion menyumbang nilai dampak sebesar 10,19 Pt atau 43,2% dari keseluruhan nilai dampak.Beberapa dampak lingkungan yang timbul diantaranya adalah acidification atau pengasaman yang terjadi pada lingkungan yang disebabkan oleh proses pemanasan; ozone formation (human) atau terbentuknya ozon pada proses distribusi produk jadi dan transportasi bahan baku. Rekomendasi perbaikan yang diberikan adalah dengan mengganti moda transportasi pada distribusi produk jadi dengan menggunakan kapal laut dan melakukan maintenance secara berkala pada mesin pellet
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
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
