    Batubara adalah salah satu sumberdaya alam yang masih sangat dibutuhkan untuk memenuhi kebutuhan energi nasional. Konsumsi batubara Indonesia setiap tahun mengalami peningkatan sekitar 13.4 persen per tahun (BPPT, 2013). Hal tersebut berdampak pada produksi batubara nasional yang terus meningkat, sehingga menuntut adanya perluasan areal pertambangan batubara. Salah satu wilayah yang akan menjadi perluasan areal pertambangan batubara adalah kawasan hutan Bukit Munggu, Kelurahan Tanjung Enim, Provinsi Sumatera Selatan. Namun, perluasan areal pertambangan batubara harus mengorbankan beberapa nilai lingkungan. Penelitian ini bertujuan untuk mengestimasi manfaat dan biaya pertambangan batubara, mengestimasi nilai ekonomi sumberdaya kawasan hutan Bukit Munggu, dan menganalisis biaya dan manfaat ekonomi rencana kegiatan konversi kawasan hutan Bukit Munggu menjadi pertambangan batubara. Metode yang digunakan dalam penelitian ini adalah valuasi nilai ekonomi kawasan hutan menggunakan Contingen Valuation Method (CVM) dan analisis market value serta metode analisis market value untuk pertambangan batubara, sedangkan untuk analisis biaya dan manfaat ekonomi kegiatan konversi menggunakan B/C rasio. Hasil penelitian menunjukkan bahwa manfaat yang dapat dihasilkan dari produksi batubara di kawasan hutan Bukit Munggu adalah sekitar empat triliun rupiah per tahun, biaya untuk pertambangan batubara adalah sekitar satu triliun rupiah per tahun, dan Total Economic Value (TEV) sebagai opportunity cost adalah sekitar seratus tujuh puluh ribu triliun rupiah per tahun. Berdasarkan hasil perhitungan didapatkan B/C rasio dari kegiatan konversi adalah < 1. Hasil tersebut menunjukkan bahwa konversi lahan kawasan hutan Bukit Munggu menjadi pertambangan batubara perlu dipertimbangkan kembali.Coal is one of natural resources that is still needed to meet the need of national energy. The consumption of Indonesian coal increases about 13.4 persen every year (BPPT, 2013). This influeces the production of national coal which keeps increasing so that this requires the extension of coal mining area. One of the areas that will be become the coal mining area extension are Bukit Munggu forest area, Tanjung Enim District, South Sumatra Province. However, this extension must sacrifice some environmental value. This research aimed to estimate the cost and benefit of coal mining, to estimate the economic value of Bukit Munggu forest resources, and to analyze the economic cost and benefit of plan to change the function of Bukit Munggu forest to coal mining. The method used in this research was valuation of economic value of forest area using Contingen Valuation Method (CVM) and market value analysis and the method of market value analysis for coal mining. Whereas the analysis of economic cost and benefit of conversion activity used B/C ratio. The results showed that the benefit yielded from the coal production in Bukit Munggu forest area was about four trillion rupiah per year, cost for coal mining was about one trillion rupiah per year, and total economic value (TEV) as the opportunity cost was about one hundred seventy thusand trillion rupiah per year. Based on the calculation result, B/C ratio obtained from conversion activity was < 1. The result showed that the land conversion of Bukit Munggu forest area to coal mining should be reconsidered

    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

    Get PDF
    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

    Get PDF
    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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
