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
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

Kebutuhan dan Ketersediaan Lahan Cadangan Untuk Mewujudkan Cita-Cita Indonesia Sebagai Lumbung Pangan Dunia Tahun 2045
No full text<p>Arable land availability for agricultural extensification is a determining factor to achieve Indonesia’s food self-sufficiency and to become the world food supplier in 2045. This study aimed to evaluate land reserves for future agricultural development. Spatial analysis was conducted using land cover map, peatland distribution map, indicative map of suspension of new permits, forest status map, licensing map, and agricultural land use recommendation map. The land assumed to be potentially available should be (i) idle land covered by shrub as well as bare land, (ii) agronomically suitable for agriculture, (iii) within the designated area of non-forest uses (APL), conversion production forest (HPK), or production forest (HP), (iv) outside the moratorium area, and (v) outside the licensed area. Analysis results show that out of 29.8 million hectares of idle land, only about 7.9 million hectares are potentially available for future agricultural extensification. The available potential land area is much less than that required to meet the self-sufficiency target and to become the world food storage by 2045, i.e. of 5.3 million hectares for rice crop, shallot and sugar cane, and about 10.3 million hectares for upland rice, maize, soybean, peanut, mungbean, sugar cane, shallot, cassava, and sweet potato. Therefore, the main strategies to take are intensification of existing agricultural land and a strict control of agricultural land conversion.</p><p> </p><p>Abstrak</p><p>Ketersediaan lahan untuk ekstensifikasi lahan pertanian menjadi salah satu faktor penentu keberhasilan untuk mempertahankan swasembada pangan dan untuk menjadikan Indonesia sebagai lumbung pangan dunia menjelang tahun 2045. Penelitian ini bertujuan untuk mengevaluasi cadangan lahan yang tersedia untuk pengembangan areal pertanian ke depan. Analisis spasial dilakukan menggunakan peta tutupan lahan, peta sebaran lahan gambut, peta indikatif penundaan pembukaan izin baru, peta status kawasan hutan, peta perizinan, dan peta arahan tata ruang pertanian. Lahan yang diasumsikan potensial tersedia adalah lahan yang (i) lahan telantar yang ditutupi semak belukar dan lahan terbuka, (ii) secara agronomis sesuai untuk pertanian, (iii) berada pada peruntukan kawasan areal penggunaan lain (APL), hutan produksi konversi (HPK), hutan produski (HP), (iv) berada di luar areal moratorium, dan (v) berada di luar areal yang sudah memiliki perizinan. Hasil analisis menunjukkan bahwa dari sekitar 29,8 juta ha lahan telantar, hanya sekitar 7,9 juta ha yang berpotensi tersedia untuk ekstensifikasi pertanian masa depan. Luas lahan potensial tersedia ini jauh lebih rendah dari kebutuhan lahan untuk memenuhi target swasembada dan mewujudkan Indonesia sebagai lumbung pangan dunia menjelang 2045 yaitu 5,3 juta ha untuk padi sawah, bawang dan tebu dan sekitar 10,3 juta ha untuk padi gogo, jagung, kedelai, kacang hijau, kacang tanah, tebu, bawang merah, ubi jalar, ubi kayu. Oleh karena itu, strategi utama yang harus ditempuh adalah intensifikasi lahan pertanian eksisting dan pengendalian konversi lahan pertanian secara ketat.</p></jats:p
