Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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

Full text linkAbstract
Steel material has an important role in the development of construction technology. High tensile strength, durable, and lighter than concrete, makes steel structures widely used in the construction of transportation infrastructure, especially for long-span bridges and underwater tunnels. In this study, the opportunities for using steel construction for use in the construction of long-span bridges, namely cable stayed bridges or cable suspension bridges, and in underwater tunnels are examined. This study shows that the choice of long-span bridge type or technology is largely determined by local conditions and the planned bridge span length. The use of steel tubes for underwater tunnel construction can be an alternative for use in the construction of underwater tunnels to be built in the new capital city of Indonesia.

Abstrak
Material baja memiliki peran penting dalam pengembangan teknologi konstruksi. Kuat tarik tinggi, tahan lama, dan lebih ringan dibandingkan dengan beton, membuat struktur baja digunakan secara luas dalam pembangunan infrastruktur transportasi, khususnya untuk jembatan bentang panjang dan terowongan bawah laut. Pada studi ini dikaji peluang penggunaan konstruksi baja untuk digunakan pada konstruksi jembatan bentang panjang, yaitu jembatan pancang atau jembatan gantung, dan pada terowongan bawah laut. Studi ini menunjukkan bahwa pemilihan tipe atau teknologi jembatan bentang panjang sangat ditentukan oleh kondisi setempat dan panjang bentang jembatan yang direncanakan. Penggunaan tabung baja untuk konstruksi terowongan bawah laut dapat menjadi salah satu alternatif untuk digunakan dalam pembangunan terowongan bawah laut yang akan dibangun di Ibu Kota Nusantara.

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
PEMBANGUNAN JEMBATAN BENTANG PANJANG DI INDONESIA (Studi Kasus: Jembatan Bentang Panjang Pulau Balang)
Full text linkAbstract
A long-span bridge is a bridge with a very wide distance between pillars. This type of bridge is very much needed in Indonesia, because it plays a vital role in connecting the archipelago regions in Indonesia and speeding up land transportation, reducing logistics costs, supporting regional economic growth, and facilitating the distribution of goods and tourism connectivity. Many long-span bridges have been built in Indonesia, but the type of structure chosen needs to consider technical, non-technical, and cost aspects. In principle, there are three challenges in the construction of long-span bridges, namely: (1) technical and structural challenges, (2) challenges related to logistics and location, and (3) non-technical and social challenges. Based on observations made on the Balang Island Bridge Construction Project, this study shows that the main technical and structural challenges during the construction of the Balang Island Bridge are the condition of the waters in the Balikpapan Strait with strong currents and the need for large-diameter deep foundations to withstand extreme loads from waves, wind, and earthquakes. In addition, there are challenges related to the procurement of materials from outside Kalimantan Island and the need for multi-agency coordination to expedite the construction process. Meanwhile, non-technical and social challenges relate to land acquisition, local social and economic impacts, environmental issues, and bridge operations and governance.
Keywords: bridge; long-span bridge; bridge construction; land acquisition
Abstrak
Jembatan bentang panjang merupakan suatu jembatan dengan jarak antarpilar yang sangat lebar, Jembatan seperti ini sangat dibutuhkan di Indonesia, karena berperan vital dalam menghubungkan wilayah kepulauan yang terdapat di Indonesia serta mempercepat transportasi darat, menekan biaya logistik, mendukung pertumbuhan ekonomi daerah, dan mempermudah distribusi barang dan konektivitas pariwisata. Jembatan bentang panjang sudah banyak dibangun di Indonesia, namun tipe struktur yang dipilih perlu memperhatikan aspek-aspek teknis, nonteknis, dan biaya. Pada prinsipnya, terdapat 3 tantangan dalam pembangunan jembatan bentang panjang, yaitu: (1) tantangan yang bersifat teknis dan struktural, (2) tantangan yang terkait dengan logistik dan lokasi, dan (3) tantangan yang bersifat nonteknis dan sosial. Berdasarkan pengamatan yang dilakukan pada Proyek Pembangunan Jembatan Pulau Balang, studi ini menunjukkan bahwa tantangan utama yang bersifat teknis dan struktural saat pelaksanaan konstruksi jembatan Pulau Balang adalah kondisi perairan di Selat Balikpapan yang berarus deras serta kebutuhan akan fondasi dalam berdiameter besar untuk menahan beban ekstrem gelombang, angin, dan gempa. Selain itu, terdapat tantangan yang terkait dengan pengadaan material dari luar Pulau Kalimantan dan perlunya koordinasi multilembaga untuk mempercepat proses konstruksi. Sedangkan tantangan yang bersifat nonteknis dan sosial terkait dengan pembebasan lahan, dampak sosial dan ekonomi lokal, masalah lingkungan, dan operasional dan tata kelola jembatan.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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

No full textWe 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
