    The Central Sulawesi – Lamonae – Landawe border section is designated as a national route that links the Southeast Sulawesi region with Central Sulawesi, specifically the mining industrial district of Morowali City. This route facilitates not only community mobilization but also the transportation of heavy mining equipment. Daily, the road endures heavy vehicle traffic carrying logistics, which increases the volume and load on this route, leading to pavement layer damage and a decline in service quality. This study aims to analyze the road surface conditions and determine the appropriate handling program using the Surface Distress Index (SDI) and International Roughness Index (IRI) methods, spanning from STA 0+000 to STA 5+500 over a segment length of 5.5 km. Subsequently, it plans the pavement layer thickness design for segments with severe surface damage using the 2017 Pavement Design Manual. The study results indicate that, according to the SDI method, 47% of the road is in good condition, 24% in moderate condition, 16% in minor damage, and 13% in severe damage. According to the IRI method, 27% of the road is in good condition, 49% in moderate condition, 15% in minor damage, and 9% in severe damage. Based on SDI and IRI values, a handling program comprising routine maintenance, periodic maintenance, and reconstruction is established. The pavement layer thickness calculation, based on the 2017 Pavement Design Manual, recommends asphalt pavement with granular base layers, comprising AC WC with a thickness of 40 mm, AC BC with 60 mm, AC Base with 80 mm, and Class A Granular Base with a thickness of 300 mm, along with subgrade improvement with a planned thickness of 200 mm.&nbsp

    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

    Pengaruh Penggunaan Serat Ijuk Pada Campuran Beton Aspal Dengan Metode Kepadatan Mutlak Terhadap Peningkatan Tegangan Tarik

    Di Indonesia sendiri campuran beraspal panas untuk perkerasan lentur dirancang menggunakan metode Marshall . Perencanaan Marshall tersebut menetapkan untuk kondisi lalu lintas berat dengan pemadatan benda uji sebanyak 2x75 tumbukan. Namun metode ini belum cukup untuk menjamin kinerja campuran beraspal yang digunakan untuk lalu lintas berat/tinggi dengan suhu tinggi dalam mengatasi terjadinya kerusakan dini.. Metode kepadatan mutlak dimaksudkan sebagai kepadatan tertinggi yang dapat dicapai oleh campuran sehingga campuran tersebut tidak dapat menjadi padat lagi, untuk memperkecil pori dan rongga pada campu

    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
