    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

    Muhammad Yudi Pratama, 2023 " PRODUCTION PLANNING ANALYSIS TO OPTIMIZE PRODUCTION COSTS WITH THE AGGREGATE PLANNING METHOD AT PT. YOUNGEST SON". Industrial engineering thesis report, Faculty of Engineering and Computer Science, Pancasakti University, Tegal 2023. The primary objective of this investigation is to assess the projected production demand for the upcoming year. This forecast will serve as a foundational basis for managerial decision-making within the company to ascertain the most suitable course of action. In tandem, the utilization of aggregate planning aims to pinpoint an operational approach for production that optimizes efficiency and effectiveness, thereby aligning production with the stipulated plans and consequently bolstering company revenues. The research encompassed the evaluation of three distinct techniques: the simple moving average method, the weighted moving average method, and the exponential smoothing method. From the study's findings, it can be deduced that the exponential smoothing forecast technique, characterized by an alpha coefficient of 0.50 and exhibiting a Mean Absolute Percentage Error (MAPE) of 54.57%, was chosen as the preferred forecasting method for the period spanning May 2023 to April 2024. In conjunction, the adopted aggregate planning strategies encompass the Power control method, Overtime method, and Mixed method. Throughout the research conducted at PT. Youngest Son, during the period extending from May 2023 to April 2024, the overtime method emerged as the most advantageous strategy. This approach demonstrated superior efficiency and effectiveness when compared to the alternatives, notably yielding an optimal total cost of Rp. 1,345,000,000,-. Keywords : simple moving average, weighted moving average and exponential smoothing method

    Research has been conducted to study the community compotition of Macrofauna soil in the anorganic and organic in Pengambaten village Merek Subdistrict at karo regency north sumatera. Sampling area assessed through “ Purposive Random Sampling” in which Macrofauna of soil was collected by using kuadrat and hand sortir. There were 3 phylum, 7 class, 14 ordo, 21 families dan 23 spesies makrofauna of soil. The density of macrofauna soil in organic farmland was higher than the density of macrofauna in anorganic farmland. The attendence of frequent for accidental, assesori, absolut and constan categories. There were five species macrofauna of soil that have relative density ≥ 10% and attendant fresquency≥ 25%, and they were categories as bioindicators, namely Euborellia sp ., Geophillus flavus, Monomorium pharaonis, Pheretima posthuma dan Pontoscolex corethrurus. The highest value of species compotition in anorganic farmland was Pontoscolex corethrurus and in organic farmland was Pheretima posthuma.Penelitian ini telah dilakukan untuk mempelajari Komposisi Komunitas Makrofauna Tanah Pada Lahan Pertanian Anorganik dan Organik Di Desa Pengambaten Kecamatan Merek Kabupaten Karo Provinsi Sumatera Utara. Penentuan titik sampling menggunakan Purposive Random Sampling dimana pengambilan sampel Makrofauna tanah menggunakan metode Kuadrat and Hand Sortir. Hasil penelitian ditemukan 3 filum, 7 kelas, 14 ordo, 21 famili dan 23 spesies makrofauna tanah. Nilai Kepadatan total Makrofauna tanah pada pertanian organik lebih tinggi dibandingkan dengan pertanian anorganik. Frekuensi kehadiran pada kedua lokasi, yaitu aksidental, assesori, konstan dan absolut. Lima spesies Collembola permukaan tanah yang memiliki nilai KR ≥ 10% dan FK ≥ 25% dan juga sebagai bioindikator pada lokasi penelitian yaitu Euborellia sp ., Geophillus flavus ., Monomorium pharaonis., Pheretima posthuma., dan Pontoscolex corethrurus. Urutan pertama komposisi spesies Makrofauna tanah pada pertanian anorganik adalah Pontoscolex corethrurus dan pada pertanian organik yaitu Pheretima posthuma.Skripsi Sarjan

    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

    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
