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
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
Pemanfaatan Limbah Isi Rumen Sapi Menjadi Kompos di Rumah Potong Hewan Kota Bekasi
Get PDFMetode penelitian yang digunakan adalah deskriptif exsperimental, penilitian ini memanfaatkan limbah isi rumen sapi dan sampah organik menjadi kompos dengan variasi komposisi 1:1 (50% limbah isi rumen sapi : 50% sampah organik) dan 3:1. (75% limbah isi rumen sapi : 25% sampah organik). Pengomposan ini dilakukan selama 30 hari dan dilakukan pemantauan suhu dan pH, selain itu pengamatan karakteristik fisik kompos pada bau, warna dan tekstur. Kompos yang sudah matang dilakukan analisis yang meliputi parameter C, N, P, K dan kadar air pada variasi 1 dan variasi 2. Pada variasi 1 dan 2 hanya ada 3 parameter yang memenuhi standar yaitu nitrogen, pospor, kalium. Parameter lainnya yaitu kadar air, rasio C/N dan kadar C-organik belum memenuhi standar. Kompos yang memberikan kandungan yang paling baik berasal dari variasi 2 dengan komposisi campuran 3:1
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
Analisis Pengaruh Potongan Harga, Kepercayaan, Iklan di Internet Terhadap Keputusan Pembelian Pada E-Commerce Tokopedia
Get PDFPenelitian ini merupakan studi empiris dengan judul “Analisis Pengaruh Potongan Harga, Kepercayaan, dan Iklan di Internet terhadap Keputusan Pembelian pada E-Commerce Tokopedia”. Penelitian ini bertujuan untuk menganalisis pengaruh variabel potongan harga, kepercayaan, dan iklan di internet terhadap variabel keputusan pembelian konsumen. Populasi dalam penelitian ini adalah responden yang berumur ≥17 tahun, pernah menggunakan e-commerce Tokopedia sebanyak ≥3 kali dan jangka waktu terakhir bertransaksi di Tokopedia < 2 bulan yang lalu dan berdomisili di Kota Purwokerto. Sampel penelitian ini sebanyak 96 responden diambil menggunakan metode purposive sampling. Berdasarkan hasil penelitian dengan menggunakan analisis regresi linear berganda diolah dengan software SPSS menunjukkan bahwa variabel potongan harga dan kepercayaan signifikan berpengaruh positif terhadap keputusan pembelian, sedangkan variabel iklan di internet tidak signifikan dan tidak berpengaruh terhadap keputusan pembelian. Variabel potongan harga dinilai responden memenuhi harapannya, besarnya potongan harga yang diberikan Tokopedia membuat konsumen tertarik membeli karena harganya menjadi paling murah jika dibandingkan harga di e-commerce lainnya. Responden berpendapat bahwa akan lebih bermanfaat jika konsumen membeli produk yang terdapat potongan harga dengan kuantitas yang banyak sekaligus karena adanya cashback yang semakin besar. Responden memiliki kepercayaan yang tinggi pada Tokopedia. Hal ini dikarenakan adanya kejujuran yang Tokopedia berikan, sistem transaksi di Tokopedia yang aman. Responden berpendapat bahwa produk yang dikirim sampai di tempat tepat pada waktunya. Selain itu responden juga berpendapat bahwa respon dari Tokopedia cepat saat ada pertanyaan dan tanggap saat konsumen mengalami masalah seperti kerusakan pada produk atau terdapat produk yang cacat. Variabel iklan di internet dinilai responden menarik dan dapat menyampaikan informasi dengan jelas, namun iklan Tokopedia di internet tidak membuat responden melakukan pembelian di Tokopedia, hal ini dikarenakan terkadang iklan tersebut terlalu sering muncul sehingga mengganggu sehingga hanya dilihat sekilas oleh responden. Keputusan pembelian yang dilakukan bukanlah dikarenakan setelah melihat iklan di Tokopedia di internet. Tokopedia perlu memberikan potongan harga yang lebih besar pada setiap jenis kategori produk sehingga sesuai dengan produk yang dibutuhkan konsumen. Selain itu, Tokopedia juga perlu lebih memberikan sistem yang lebih aman agar rasa percaya konsumen pada Tokopedia lebih tinggi. Tokopedia sebaiknya jangan terlalu fokus dalam melakukan promosi iklan di internet karena tidak memiliki pengaruh terhadap keputusan pembelian di Tokopedia
