Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Pengelolaan Plasma Nutfah Tanaman Terintegrasi dengan Program Pemuliaan
<p>Plant breeding, as an applied of plant genetics, is based and is supported by various subdisciplines of genetic sciences, includeing plant germplasm, classical genetics, molecular genetics, cytogenetics, gene-transformation techniques, etc. Linkage and team work system between plant germplasm management and plant breeding program is most required, since the success of plant breeding maybe obtained from the contribution of gene donor parents, derived from the germplasm management. Without the flow of genes from the germplasm collection, varieties produced by the plant breeder would suffer a narrow genetical based or a bottle-necking genetic based. Plant germplasm research is an integral part of the germplasm management, aimed to (1) evaluate the genetic variation of the germplasm collection, to be readily available for the breeding program and to be used for scientific publications, (2) tracing the origin of plant species, and (3) officially release a selected germplasm, containing new economic gene (s). The linkage between germplasm management and plant breeding research program could be facilitated through the following activities (1) identifying an elit germplasm for varietal release, (2) selection and stabilization of a promising germplasm accession for possible varietal releases, (3) use of germplasm accession as a gene donor parent to incorporate adaptive genes into improved variety, (4) use of germplasm accession for a specific donor gene, (5) use of germplasm to broaden the genetical base of varieties through an introgression and nobilization, (6) use of germplasm to improve the genetic value of the breeding population, and (7) to develop multiple crossess involving many parents to broaden the genetical base of the breeding population. Another important function of the germplasm management is to conserve accessions carrying genes which may be useful in the future, to anticipate the dynamic changing of biological and environmental stresses on crop. Germplasm management is considered successfully conducted when it is continously supplying donor gene parents to breeders for parental crosses on their breeding program, conversely, breeding program in considered successfully managed, when it uses the rich genetic variability available on the germplasm collection. Separating the organizational units among the breeding program, germplasm management and molecular genetic research, is only for enhancing the intensity of the research, but should not separate the linkage program of the research.</p><p> </p><p><strong>Abstrak</strong></p><p>Pemuliaan tanaman merupakan ilmu genetika terapan yang didukung oleh berbagai cabang ilmu kegenetikaan, termasuk plasma nutfah, genetika klasik, genetika molekuler, sitogenetika, dan genetika transformasi. Keterpaduan antara pengelolaan plasma nutfah dengan pemuliaan tanaman tidak dapat ditawar, karena keberhasilan pemuliaan sangat tergantung dari ketersediaan sumber gen yang disediakan oleh pengelola plasma nutfah. Tanpa kontribusi sumber gen dari pengelola plasma nutfah, hasil pemuliaan tanaman mengalami penyempitan kandungan genetik, atau terjadi gejala leher botol genetik. Penelitian plasma nutfah merupakan bagian integral dari pengelolaan materi plasma nutfah, bertujuan untuk (1) menggali kekayaan sifat genetik plasma nutfah guna penyediaan tetua persilangan dan bahan publikasi ilmiah, (2) menelusuri asal-usul spesies tanaman, (3) melepas secara resmi plasma nutfah sebagai sumber gen yang diakui kepemilikannya. Keterkaitan pengelolaan plasma nutfah dengan program pemuliaan dapat dilaksanakan melalui (1) pemanfaatan langsung aksesi plasma nutfah elit untuk dilepas sebagai varietas unggul, (2) pemurnian dan pemantapan populasi aksesi plasma nutfah sebagai calon varietas, (3) pemanfaatan aksesi plasma nutfah sebagai donor gen untuk rekombinasi gen-gen unggul adaptif, (4) plasma nutfah sebagai donor gen spesifik, (5) plasma nutfah sebagai bahan perluasan latar belakang genetik varietas melalui proses introgresi dan nobilisasi, (6) pemanfaatan plasma nutfah untuk perbaikan genetik populasi seleksi, dan (7) pembentukan populasi dasar yang mengandung keragaman genetik luas melalui persilangan banyak tetua. Fungsi pengelolaan plasma nutfah lainnya adalah melestarikan sumber daya genetik untuk kebutuhan gen di masa depan, agar dapat menyediakan gen-gen untuk mengantisipasi perubahan ras patogen dan tipe baru serangga hama yang bersifat dinamis, serta penyediaan gen guna mengatasi cekaman abiotik alamiah. Pengelolaan plasma nutfah dinilai berhasil apabila telah mampu menyediakan aksesi plasma nutfah sebagai sumber gen donor dalam program pemuliaan. Pemuliaan tanaman berhasil secara optimal apabila telah memanfaatkan keragaman genetik sifat yang diinginkan, yang tersedia dalam koleksi plasma nutfah. Keterpisahan kelembagaan antara unit kerja pengelolaan plasma nutfah dengan program pemuliaan tidak boleh membatasi keterpaduan program penelitian antara kedua cabang disiplin keilmuan tersebut.</p></jats:p
Green Agriculture dan Green Food sebagai Strategi Branding dalam Usaha Pertanian
EnglishTechnology application during the Green Revolution had been successfully worked to overcome the national food production deficit. However, due to the policy to maintain low food prices, the increase of production failed to improve the actual farmer’s income. The strategy to differentiate agricultural products with premium prices is set through a logo or brand seal on the products, means that the products are explicitly embedded with environment friendly images, safe and sustainable. The suggested logo is “Green Food” indicated that the products come from “green Agriculture”. The Green Agriculture is a modern agricultural practice using a balanced and controlled agrochemical according to certain protocol to guarantee an environment friendly production process and safety consume of the products. Green Agriculture and the Green Food easier to apply compared to that of Good Agriculture Practices. If Indonesia to adopt Green Agriculture and Green Food, a new regulation called “Indonesian Green Agriculture and Green Food Protocol” need to be formulated. For operational reason, the need to adopt Green Agriculture and Green Food should come from the incumbent and influenced government officials. Green Agriculture and Green Food is a branding strategy to increase the bargaining position and the competitive level of Indonesian agricultural products at both domestic and international markets. China has applied Green Agriculture and Green Food since 1990 and in 2008, 6 million of China’s farmers have adopted the practices along with 816 post-harvest processors with annual Green Food total volume amounted to 42 million ton and US$ 2.32 billion of export value. In Indonesia, Green Food has a high opportunity to get market segment due to the increase awareness on environment quality in addition to higher prices the farmers could enjoy compared to the price of conventional products. Through Green Agriculture and Green Food, the maintenance of environment quality and safety of food consumption will be a collective responsibility of the farmers, processors, traders, and consumers. Green Agriculture and Green Food is the “eco-farming with modern techniques and modern management by modern farmers for modern societies and modern world”.IndonesianPenerapan teknologi Green Revolution telah berhasil mengatasi kekurangan produksi pangan nasional, namun karena kebijakan pemerintah untuk menjaga harga pangan murah, maka kenaikan produksi tidak meningkatkan pendapatan petani secara nyata. Strategi diferensiasi produk pertanian untuk memperoleh harga premium adalah dengan memberi logo atau brand pada produk, yang secara eksplisit mencitrakan sebagai produk yang ramah lingkungan, aman konsumsi dan berkelanjutan. Logo yang disarankan adalah Green Food yang produknya berasal dari Green Agriculture. Green Agriculture merupakan praktek pertanian modern dengan penggunaan sarana agrokimia secara terkendali oleh ketentuan protokol, sehingga menjamin proses produksi ramah lingkungan dan produk panennya aman konsumsi. Ketentuan Green Agriculture dan Green Food lebih mudah dioperasionalkan dibandingkan dengan ketentuan Good Agriculture Practices. Apabila Indonesia akan mengadopsi Green Agriculture dan Green Food, perlu disusun ketentuan yang dapat disebut Indonesian Green Agriculture and Green Food Protocol. Keinginan untuk mengadopsi Green Agriculture dan Green Food harus datang dari pejabat berwenang sehingga operasionalisasinya dapat dilaksanakan. Green Agriculture dan Green Food merupakan strategi branding untuk meningkatkan posisi tawar dan daya saing produk pertanian Indonesia di dalam negeri dan di pasar internasional. China telah menerapkan Green Agriculture dan Green Food sejak tahun 1990 dan pada tahun 2008 diikuti oleh 6 juta petani dan 816 perusahaan pengolah hasil panen, dengan total produk Green Food setahun mencapai 42 juta ton dan nilai ekspor sebesar 2,32 milyar dolar. Di Indonesia, Green Food berpeluang mendapatkan segmen pasar cukup besar oleh meningkatnya kesadaran masyarakat terhadap mutu lingkungan dan petani memperoleh harga yang lebih baik dibandingkan produk pangan konvensional. Melalui Green Agriculture dan Green Food, maka pemeliharaan mutu lingkungan dan keamanan konsumsi pangan menjadi tanggung jawab bersama, oleh petani, pengolah produk, pedagang dan konsumen. Green Agriculture dan Green Food merupakan “eco-farming with modern techniques and modern management by modern farmers for modern societies and modern world”
Dispelling the Myths Behind First-author Citation Counts
We 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

We 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
