    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

    Brownies are one type of snack that is liked by many people, both children and adults. The types of brownies on the market are generally high in sugar and low in fiber. Seaweed brownies are a snack alternative by increasing the fiber content. The main purpose of this study was to determine the effect of adding seaweed to the organoleptic characteristics of Brownies. In this study the addition of seaweed as the main factor was designed using a completely randomized design with a unidirectional pattern, the experimental models were B0 (0 grams), B1 (50 grams), B3 (100 grams), and B3 (150 grams). grams). The tests carried out were organoleptic tests (scoring and hedonic tests). The results of the scoring test on the parameters of color, aroma, taste, and texture resulted in significant differences in each treatment. The hedonic test showed that the most preferred sample for the overall parameter was brownies without the addition of seaweed with code B1. The samples of brownies with 50 grams, 100 grams, and 150 grams of seaweed were still accepted by the panelists with a range of likes and dislikes. The addition of 150 grams of seaweed on the color parameter is not preferred

    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

    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

    EKSTRAKSI BERAS HITAM SIRAMPOG BERBANTU GELOMBANG MIKRO (MICROWAVE ASSISTED EXTRACTION (MAE))

    Full text link
    Beras hitam sirampog varietas lokal Kabupaten Brebes memiliki sejuta khasiat, salah satunya kandungan antosianin yang baik bagi kesehatan. Komponen aktif yang dimiliki beras hitam perlu dilakukan ektraksi untuk mempermudah pengaplikasian. Metode ekstraksi MAE (Microwave Assisted Extraction) cocok digunakan untuk ekstraksi komponen yang rentan terhadap panas, karena dapat dikontrol melalui daya dan waktu ekstraksi. Tujuan penelitian untuk mengetahui pengaruh daya dan lama waktu ekstraksi berbantu gelombang mikro (MAE) terhadap rendemen dan pH ekstrak beras hitam sirampog. Rancangan penelitian menggunakan rancangan acak lengkap yang terdiri dari 2 faktor yaitu variasi daya (100,175,250 watt) dan variasi waktu ekstraksi (3,6,9 menit). Data dianalisis dengan menggunakan Uji F dengan taraf kepercayaan 95% dan jika berpengaruh nyata dilanjutkan dengan analisis DMRT  (Duncan's Multiple Range Test) dengan taraf 95%. Hasil penelitian yaitu rendemen tertinggi (45,75%) dihasilkan pada perlakuan D2W1(175 watt dan 3 menit), sementara rendemen terendah (18,75%) pada perlakuan D3W3 (250 watt dan 9 menit). pH tertinggi (pH 6,56) dihasilkan pada perlakuan D2W3 (175 watt dan 9 menit) dan D3W3 (250 watt dan 9 menit), sementara pH terendah (6,35)  terjadi pada perlakuan D1W1 (100 watt dan 3 menit)

    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
