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
PENGARUH KEBISINGAN TERHADAP KARYAWAN DI PLTD SENTRAL II PT. SEMEN PADANG
Full text linkAbstract
This research aim to analyze the noise intensity in PLTD Sentral II PT Semen Padang. Analysing physiological trouble, psycological trouble, trouble of communication and hearing trouble from noise to employees in PLTD Sentral II PT Semen Padang. This research have the character of quantitative descriptive that is see the noise intensity and its influence to employees in PLTD Sentral II PT Semen Padang. For the data of noise intensity conducted by measurement use the appliance of sound level metre and while for the data of employees feeling noise influence conducted by giving kuisioner. Analyse the data use the analyse of univariat and bivariat. Result of measurement of noise intensity in PLTD Sentral II PT Semen Padang by using appliance of sound level metre at five visible measurement dot that its intensity have exceeded the value float the boundary specified for the workplace of by ministrial decree of labour No 51/Men/1999 that is 85 dB (A). physiological trouble of laboring employees in PLTD Sentral II PT Semen Padang the field got that experiencing of physiological trouble with the sigh at most happened that is headache. Psycological trouble of laboring employees in PLTD Sentral II PT Semen Padang the field got that experiencing of psychological trouble with the sigh at most happened that is concentration less in working caused by his is clunk. Laboring employees communications trouble in PLTD Sentral II PT Semen Padang got that experiencing of communications trouble with the friends work to scream. Laboring employees hearing trouble in PLTD Sentral II PT Semen Padang got by that experiencing of hearing trouble with the sigh which is at most happened by that is ear often felt to be stuffed up
PEMANFAATAN CITRA LANDSAT 8 UNTUK PEMETAAN EKOSISTEM MANGROVE DI KOTA PADANG
Full text linkPemetaan ekosistem hutan mangrove selama ini banyak dilakukan secara terestrial dan belum banyak memanfaatkan teknologi penginderaan jauh. Kelemahan metode terestrial untuk pemetaan ekosistem hutan mangrove bila dibandingkan dengan memanfaatkan data penginderaan jauh adalah lebih baik dari segi waktu, biaya dan tenaga, sementara kelebihan secara terestrial adalah tingkat akurasi yang lebih tinggi.
Tujuan penelitian ini adalah untuk mengetahui sejauh mana data penginderaan jauh dapat dimanfaatkan dalam memetakan ekosistem hutan mangrove dan juga menghitung luasan dan persebarannya di wilayah administrasi Kota Padang Sumatra Barat. Uji akurasi dilakukan untuk proses reinterpretasi dan perbaikan, sehingga dapat diketahui tingkat akurasi dari citra LANDSAT 8 yang digunakan dalam penelitian ini.
Komposit 563 dan 567 pada citra Landsat 8 dianggap dapat menonjolkan aspek perbedaan hutan mangrove dengan hutan non-mangrove, Pantulan spektrak ekosistem mangrove berbeda dengan vegetasi non-mangrove, sehingga secara visual dan digital cukup mudah membedakan antara vegetasi mangrove dan vegetasi non-mangrove.
Hasil interpretasi citra Landsat 8 dan uji lapangan, diketahui ekosistem mangrove di wilayah Kota Padang hanya terdapat pada Kecamatan Bungus Teluk Kabung dan tidak tumbuh pada Kecamatan lain. Luas ekosistem mangrove seluas 84 Hektar
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
