    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” 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

    Sungai Porong merupakan area pembuangan Lumpur Lapindo, tidak menutup kemungkinan bahwa dengan adanya aliran lumpur lapindo mengakibatkan material lumpur tidak banyak mengendap di sepanjang sungai, tetapi mengendap di daerah muara Sungai Porong hingga ke sepanjang pantai . Oleh karena itu metode penginderaan jauh dengan citra satelit dapat menjadi solusi untuk melakukan penelitian masalah TSS (Total Suspended Solids) yang menjadi salah satu parameter dampak sedimentasi di daerah perairan tersebut. Citra satelit yang digunakan dalam penelitian ini adalah citra Landasat 8 L1T hasil perekemanan secara multi temporal pada tahun 2014 sampai dengan tahun 2016 sehingga dapat diketahui nilai dan persebaran TSS (Total Sediment Solid). Penelitian ini menggunakan 3 algoritma untuk menentukan nilai TSS yaitu, algoritma Guzman dan Santaella (2009), algoritma Syarif Budiman (2004), dan algoritma Laili (2015). Waktu penelitian dilakukan pada musim penghujan yang dilakukan pada bulan april. Daerah penelitian yang digunakan dalam penelitian ini adalah Muara Sungai Porong yaitu di sepanjang pesisir pantai Surabaya – Sidoarjo. Dari hasil pengolahan data dan analisa didapatkan nilai TSS dari tahun 2014 – 2016 bervariasi antara 1.4 mg/l – 118 mg/l. Uji validasi nilai TSS yang paling baik dalam penelitian ini adalah perhitungan menggunakan algoritma Laili (2015) dengan Koefisien Determinasi (R) sebesar 73,81 % dan regresi linier (R2) sebesar 0.5449. Daerah yang mengalami dampak sebaran TSS tinggi adalah muara Sungai Porong, Pantai Pasuruan, muara Kali Alo, selatan Sungai Porong, dan daerah pantai utara Kali Alo. Nilai dan sebaran TSS dipengaruhi oleh pasang surut, arus, angin, dan gelombang. Hasil analisis dan pengolahan data ini dapat dijadikan sebagai bahan referensi dalam penelian selanjutnya. ================================================================================================================== Porong River is the Lapindo mud disposal area , did not rule out the possibility that the presence of the Lapindo mud flow the resulting sludge is not much material settles along the river , but settles in the area up to the Porong River along the coast . Therefore , methods of remote sensing satellite imagery can be a solution to the problem of research TSS (Total Suspended Solids ) , which Became one of the parameters of the effect on sedimentation in this coast area. Satellite imagery used in this study is Landsat 8 imagery, image recording results in multi temporal from 2014 to 2016 so that can know the value and distribution of TSS (Total Suspended Solid). This study uses three different algorithms to Determine the value of TSS , the algorithm Guzman and Santaella (2009 ) , the algorithm Syarif Budiman (2004 ) , and the algorithm Laili ( 2015) . This research was conducted during the rainy season in April . The area of research used in this research is the which is the Porong River estuary along the coast of Surabaya - Sidoarjo. From the results of data processing and analysis of the TSS values obtained in 2014 - 2016 in the study area varies between 1.4 mg / l – 118 mg / l. Validation Test of TSS best value in these studies is a calculation using the algorithm Laili ( 2015) with a coefficient of determination ( R ) amounted to 73.81 % and linear regression ( R2 ) of 0.5449 . Areas affected by the distribution of high value TSS is Porong River estuary, south of Kali Porong, Pasuruan beach, Kali Alo estuaries, and coastal areas north of Kali Alo. TSS values and distribution are influenced by tides, currents flow, wind, and waves. The results of data processing and analysis can be used as reference material in the next

    Tender adalah kegiatan yang bertujuan untuk menyeleksi, mendapatkan, menetapkan dan menunjuk perusahaan yang paling layak untuk mengerjakan suatu paket pekerjaan. Pemilihan penyedia untuk pekerjaan konsultansi dilakukan melalui lelang elektronik (e-Procurement). Dalam mengikuti proses e-procurement terdapat berbagai penyebab kegagalan yang dilakukan oleh penyedia jasa. Faktor-faktor penyebab kegagalan yang diteliti berdasarkan kombinasi beberapa literatur dan hasil penelitian terdahulu meliputi tiga faktor yaitu: Manajemen dan Perencanaan, Kebijakan dan Regulasi, Standar Teknologi. Untuk mengetahui penyebab kegagalan dalam proses e-procurement, maka perlu dilakukan analisa terhadap faktor-faktor yang dapat mempengaruhi terjadinya kegagalan tersebut. Metode analisis yang digunakan pada penelitian ini, yaitu Partial least square. Pada penelitian ini menggunakan data primer yang didapatkan dari expert judgement melalui distribusi kuesioner kepada pihak manajer proyek, manajer pengadaan atau pelaksana dari konsultan yang pernah atau sedang mengikuti proses kegiatan e-procurement di Kementerian ATR/BPN Kanwil Jawa Timur, serta dari studi literatur terdahulu. Tujuan dari penelitian ini adalah untuk mengetahui dan menemukan faktor-faktor yang paling besar mempengaruhi kegagalan penyedia jasa konsultan dalam e-procurement. Berdasarkan hasil penelitian, implementasi perencanaan dan manajemen menjadi faktor paling besar pengaruhnya terhadap kegalalan lelang (e-procurement) yaitu sebesar 49.6%. Sedangkan faktor standar teknologi berpengaruh sebesar 36.5% terhadap kegagalan lelang, serta faktor kebijakan dan regulasi tidak terbukti berpengaruh signifikan terhadap kegagalan lelang di kementerian ATR/BPN Kanwil Jawa Timur. ======================================================================================================== The providers selection for consultans works is carried out through electronic procurement (E-Procurement). To discover the consultant service providers failure and factors which influenced the failures in the e-procurement is important. The failure factors used based on literature review are planning and management, policy and regulations and technology standard. Partial Least Square (PLS) is analytical method for model fit assessment between the failure factors which is suitable for this research. The primary data is obtained by distributing questionnaires to consultans who have been participating in the e-procurement process at the Ministry of ATR/BPN Regional Office of East Java. The purpose of this study are to discover and find the most dominant factors that influence the failure of consultant service providers in e-procurement. Based on the results of the research, the implementation of planning and management is the factor that has the highest influence on the failure of the auction (e-procurement), which is 49.6%. It means that the worse planning and management value, the more inefficient failure of the auction in e-procurement will be. While the technology standard has an effect of 36.5% on auction failure, and policy and regulations factors are not proven to have a significant effect on auction failure at the Ministry of ATR/BPN East Java Regional Office

    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
