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
Analisis Karakteristik Tanah Gambut Berserat dan Dampaknya Terhadap Infrastruktur
Full text linkAbstrak Indonesia merupakan salah satu negara dengan sebaran lahan gambut yang luas. Gambut dikenal sebagai tanah yang bermasalah dalam pekerjaan konstruksi karena memiliki daya dukung yang rendah sehingga tidak dapat menopang pondasi infrastruktur. Tujuan penelitian ini adalah untuk menganalisis karakteristik tanah gambut di Kalimantan, sehingga penanganan yang tepat dapat ditentukan untuk mengatasi permasalahannya. Studi kasus pada penelitian ini adalah tanah gambut di Bereng Bengkel, Palangkaraya. Karakteristik tanah gambut diidentifikasi melalui serangkaian pengujian tanah berdasarkan Peat Testing Manual 1979. Selain itu, dilakukan juga pengujian Scanning Electron Microscopy untuk melihat morfologi tanah gambut, serta pengujian Fourier Transform Infra-Red untuk mengidentifikasi jenis senyawa yang terdapat di dalamnya. Hasil pengujian tanah di laboratorium menunjukkan bahwa tanah gambut memiliki sifat yang buruk secara geoteknik. Dari hasil pengujian SEM, diketahui adanya makropori dan mikropori pada tanah gambut yang sebagian besar ditempati oleh air. Kemudian, berdasarkan hasil pengujian FTIR, diketahui bahwa tanah gambut memiliki senyawa yang bersifat hidrofilik. Kata kunci: tanah gambut, serat gambut, infrastruktur Abstract Indonesia is one of the countries with a wide distribution of peatlands. Peat is known as a problematic soil in construction work because it has a low bearing capacity that cannot support infrastructure foundations. The objective of this research is to analyze the characteristics of peat soils in Kalimantan, so that appropriate treatments can be determined to overcome the problem. A case study of this research is the peat soil in Bereng Bengkel, Palangkaraya. The characteristics of the peat soil were identified through a series of soil tests based on the Peat Testing Manual 1979. In addition, Scanning Electron Microscopy testing was carried out to look at the morphology of the peat soil, as well as Fourier Transform Infra-Red testing to identify the types of compounds contained therein. The results of soil testing in the laboratory showed that the peat soil had poor geotechnical properties. SEM testing revealed macropores and micropores in the peat soil, most of which were occupied by water. FTIR testing showed that peat soil has hydrophilic compounds.

Evaluasi Perkuatan Eksisting Bronjong Pada Kasus Kelongsoran Jalan Cisasawi, Kecamatan Parongpong, Kabupaten Bandung Barat
Full text linkAbstrak Jalan Cisasawi mengalami kelongsoran pada tahun 2020. Usaha penanganan kelongsoran telah dilakukan oleh warga, menggunakan Bronjong. Hanya saja, perencanaan perkuatan tersebut tidak memperhitungkan persyaratan yang berlaku. Agar tidak terjadi kejadian serupa, perlu dilakukan evaluasi terhadap perkuatan tersebut. Evaluasi dimulai dengan pengumpulkan data dengan cara pengukuran geometri lereng dan pengujian tanah. Analisis stabilitas dilakukan menggunakan software Geostudio. Evaluasi dilakukan di akhir untuk mengetahui apakah konstruksi perkuatan lereng eksisting tersebut cukup aman atau tidak. Dari hasil analisis didapatkan bahwa nilai SF dari lereng eksisting (sebelum adanya bronjong) sebesar 0,504. Kondisi ini sesuai dengan lapangan yaitu lereng mengalami kelongsoran. Hasil analisis stabilitas lereng setelah diperkuat dengan Bronjong adalah SF sebesar 1,014. Nilai SF ini tidak memenuhi yang disyaratkan SNI 8460-2017 faktor keamanan dalam kondisi gempa SF lebih besar dari 1,1 sehingga diperlukan alternatif perkuatan tambahan lereng. Alternatif perkuatan tambahan lereng dilakukan memperbesar dimensi bronjong. Dari hasil analisis perkuatan tambahan didapatkan SF sebesar 1,277. Kata kunci: Perkuatan lereng, longsor, bronjong, angka keamanan Abstract Cisasawi Road experienced a landslide in 2020. Landslide handling efforts have been carried out by residents, in the form of strengthening gabions. However, the retrofitting plan does not take into account requirements. In order to avoid similar incidents, it is necessary to evaluate the reinforcement. This evaluation begins with collecting data by measuring slope geometry and soil testing. Stability analysis was performed using GeoStudio software. Evaluation is carried out at the end of the analysis to determine whether the existing slope reinforcement construction is safe enough or not. From the results of the analysis, it was found that the SF value of the existing slope (before the gabions) was 0.504. This condition is in accordance with the field, namely the slope is sliding. The result of slope stability analysis after reinforced with Gabions is SF 1.014. This SF value does not meet the required SNI 8460-2017 safety factor in earthquake conditions SF > 1.1 so that additional slope reinforcement alternatives are needed. An alternative to additional slope reinforcement is to increase the gabion dimensions. From the results of the additional reinforcement analysis, it was found that SF 1,277.

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
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
