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
Karakteristik Proses Gasifikasi Tandan Kosong Kelapa Sawit Dan Batubara Dengan Katalis Bentonit
No full textKebutuhan energi permasalahan serius yang harus dihadapioleh banyak negara, termasuk indonesia adalah sampah biomasa dan energi fosil. Biomasa tandan kosong kelapa sawit dan batubara merupakan salah satu jenis sampah biomassa kelapa sawit, dan energi fosil dari bebatuan sendimen yang tertimbun di alam juataan tahun. Kedua permasalah tersebut yang paling sulit terdegradasi karena memiliki rantai polimer panjang dengan sedikit cabang. Hal ini menyebabkan tandan kosong kelapa sawit dan batubara bersifat kuat dan sulit terdegradasi, sehingga memerlukan perlakuan khusus dalam pengolahan.
Permasalahan lain yang dihadapi oleh negara ini adalah masalah energi. Karena persediaan bahan bakar fosil dunia semakin menipis dan belum dimanfaatkan secara optimal, dan karena persediaan biomasa juga melimpah juga belum bisa dimanfaatkan secara optimal. Salah satu solusi yang tepat untuk menyelesaikan kedua permasalahan ini adala dengan proses gasifikasi dan salah satunya untuk menghemat energi dalam proses gasifikasi adalah dengan penambahan katalis.
Penelitian ini bertujuan untuk mengetahui peran bentonit pada proses gasifikasi tandan kosong kelapa sawit dan batubara dan pengaruh laju pemanasan terhadap kinerja bentonit pada proses gasifikasi. Penelitian ini dimulai dengan mengumpulkan sampel tandan kosong kelapa sawit dan batubara, kemudian sampul dihancurkan menjadi serbuk, kemudian disaring dan di ambil ukuran 50mesh. Selanjutnya dilakukan beberapa pengujian terhadap sampel yang meliputi ujia nilai kalor dan uji dekomposisi proses gasifikasi terhadap sampel.
Hasil dari penelitian ini menunjukkan bahwa bentonit mempercepat laju penyusutan massa proses gasifikasi tandan kosong kelapa sawit dan batubara hanya sampai dibawah batas kestabilan termalnya. Ketika bentonit sudah mendekati dan memasuki batas kestabilan termalnya maka performa katalitiknya semakin melemah sehingga tidak banyak membantu pada proses gasifikasi tandan kosong kelapa sawit dan batubara.
Bentonit menunjukkan performa katalitiknya yang baik pada proses gasifikasi tandan kosong kelapa sawit dan batubara pada heating rate 10°C/min yaitu meningkatkan laju penyusutan massa pada proses gasifikasi tandan kosong kelapa sawit dan batubara
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
Alternatif Penggunaan Fluid Viscous Damper pada Gedung Psikologi Universitas Islam Negeri Sunan Ampel Berlokasi di Malang
Full text linkGedung Psikologi Universitas Islam Negeri Sunan Ampel merupakan gedung beton bertulang 9 lantai menggunakan sistem Struktur Pemikul Momen Khusus (SRPMK).Proyek akhir ini merencanakan alternatif penggunaan Fluid Viscous Damper pada Gedung Psikologi Universitas Islam Negeri Sunan Ampel dengan menggunakan struktur SRPMB + Fluid Viscous Damper. Pengerjaan proyek akhir ini ada dua tahap analisa. Tahap pertama adalah permodelan struktur eksisting menggunakan SRPMK dan permodelan struktur SRPMB. Perubahan sistem rangka bangunan dari SRPMK menjadi SRPMB diharapkan untuk mengurangi kerusakan struktural pada bangunan . selanjutnya dilakukan pengecekan struktur SRPMK dan SRPMB apakah masih memenuhi persyaratan pada SNI 1726:2019 atau tidak. Dikarenakan penggunaan struktur SRPMB memiliki desain gempa yang lebih besar dibandingkan dengan SRPMK, sehingga digunakan alat bantu berupa peredam gempa yaitu Fluid Viscous Damper. Pada analisa tahap dua dilakukan permodelan dengan sistem struktur SRPMB dengan Fluid Viscous Damper. Kebutuhan kapasitas fluid viscous damper didapatkan dari perhitungan metode redaman kekakuan proporsional dengan menggunakan respon spektrum menggunakan analisis linear. Fluid viscous damper yang digunakan merupakan Fluid Viscous Damper 17180 dengan kapasitas 3000 Kn, dan dipasang sebanyak 32 buah. Fluid viscous damper dipasang dengan breising dan pemasangan secara diagonal dengan sambungan gusset plate serta Mountin Pin pada bagian ujung bracing dan Fluid viscous damper. Selanjutnya dilakukan cek kontrol dinamis dan kapasitas elemen struktur pada struktur alternatif penggunaan Fluid Viscous Damper pada Gedung Psikologi Universitas Islam Negeri Sunan Ampel. Hasilnya, penambahan alat peredam berupa Fluid Viscous Damper mampu mengurangi simpangan antar lantai terbesar pada bangunan sebesar 40 %, Gaya geser dasar mencapai 32,4 %, dan gaya aksial pada kolom hingga 20,5 %. Hasil perhitungan yang sudah memenuhi kontrol struktur dan kontrol penulangan selanjutnya akan dijelaskan pada penggambaran teknik, serta metode pelaksanaan pemasangan Fluid Viscous Damper pada gedung Universitas Islam Negeri Sunan Ampel. =================================================================================================
The Psychology Building of the State Islamic University of Sunan Ampel is a 9-story reinforced concrete building using the Special Moment Resisting Structure (SRPMK) system. This final project plans an alternative to the use of Fluid Viscous Damper in the Psychology Building of the State Islamic University of Sunan Ampel by using the SRPMB + Fluid Viscous Damper structure. The work on this final project consists of two stages of analysis. The first stage is modeling the existing structure using SRPMK and modeling the SRPMB structure. The change of the building frame system from SRPMK to SRPMB is expected to reduce structural damage to buildings. then check the structure of the SRPMK and SRPMB whether they still meet the requirements of SNI 1726:2019 or not. Due to the use of the SRPMB structure, which has a larger earthquake design than the SRPMK, so an earthquake damper is used, namely the Fluid Viscous Damper. In the second stage of analysis, modeling is carried out with the SRPMB structural system with Fluid Viscous Damper. The fluid capacity requirement of the viscous damper is obtained from the calculation of the proportional stiffness damping method using the response spectrum using linear analysis. The fluid viscous damper used is a Fluid Viscous Damper 17180 with a capacity of 3000 Kn, and 32 units are installed. Fluid
The viscous damper is braced and mounted diagonally by connecting the gusset plate and Mountin Pin at the end of the bracing and Fluid viscous damper. Next, check the dynamic control and structural element capacity on alternative structures using Fluid Viscous Damper at the Psychology Building of Sunan Ampel State Islamic University. As a result, the addition of a damping device in the form of a Fluid Viscous Damper is able to reduce the largest displacement between floors in the building by 40%, the base shear force reaches 32.4%, and the axial force on the column by up to 20.5%. The calculation results that have met the structural control and reinforcement control will then be explained in the technical drawing, as well as the implementation method for the installation of Fluid Viscous Damper in the Sunan Ampel State Islamic University building
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
