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
Pengaruh Admixture Terhadap Campuran Beton K 350 Ditinjau Dari Kuat Tekan Beton: The Effect of Admixture on K 350 Concrete Mixtures Viewed From Concrete Compressive Strength
Full text linkIn this research, we want to experiment to find out the compressive strength of medium quality concrete K-350 with ingredients added MASTER RHEOBUILD 6, whose function is to accelerate hardening, improve the quality of concrete, reduce water use and increase the value of slump. However, it should be noted that errors in dosages and how to use added ingredients can be detrimental to the quality of concrete. The results of the study show that the addition of 0.25, 0.5 and 0.75 liters per 50 kg of cement can increase the concrete compressive strength. The compressive strength of concrete with the addition of 0.25 liters/50 kg of cement has increased 362.67 kg/cm² from the normal concrete compressive strength of 350.58 kg/cm2. The addition of 0.5 liters/50 kg of cement has increased again to 373.24 kg/cm², and the addition of 0.75 liters/50 kg of cement has increased the concrete compressive strength to 379.29 kg/cm² of normal concrete. Comparison of compressive strength before and after addition of admixture with an increase of 3.45% in addition of 0.25 liters/50 kg of cement, 6.47% in addition of 0.5 liters/50 kg of cement and 8.19% in addition of 0.75 liters/50 kg of cement
Kajian Pererapan Keselamatan dan Lingkungan Kerja pada Proyek Konstruksi Gedung di Palangka Raya
No full textKeselamatan dan kesehatan kerja (K3) merupakan hal yang sangat penting dalam industri jasa konstruksi, namun demikian masalah K3 sering kali luput dari perhatian pihak-pihak yang terlibat dalam proses pelaksanaan konstruksi. Tidak jarang masalah K3 oleh sebagian kalangan cenderung diabaikan dan hanya sedikit saja pihak yang ingin memperhatikan masalah ini secara sungguh-sungguh. Kita mengetahui undang-undang tentang keselamatan dan kesehatan kerja itu ada, tetapi dalam pelaksanaannya di lapangan penggunaan alat pengaman sering kali jarang digunakan hal ini dikarenakan kurangnya pengawasan. Untuk mengurangi kecelakaan kerja, di samping menggunakan alat-alat pengaman yang sesuai aturannya, kesadaran manusia itu sendiri. Perbaikan lingkungan juga salah satu upaya pencegahan terhadap kecelakaan dan penyakit akibat kerja. Di daerah khususnya Palangka Raya belum membudaya upaya perbaikan lingkungan kerja, Hal ini dapat mengakibatkan timbulnya penyakit, penurunan derajat kesehatan atau ketidaknyamanan baik pada pekerja maupun pada warga masyarakat di sekitar tempat kerja. Tujuan dari penelitian ini adalah mengkaji penerapan keselamatan dan lingkungan kerja pada proyek konstruksi gedung di Palangka Raya, di mana untuk mengetahui dan menganalisis pengaruh faktor K3 yang terdiri dari peralatan kerja, alat kerja dan lingkungan kerja secara simultan dan parsial terhadap kinerja proyek di Kota Palangka Raya. Metode yang digunakan dalam penelitian ini dengan membagikan kuisioner kepada para pemilik pekerjaan, kontraktor pelaksana dan konsultan pengawas, dari hasil kuisioner tersebut dianalisa dengan analisis faktor dan analisis regresi berganda. Hasil dari penelitian adalah sebagai berikut faktor peralatan kerja, alat kerja dan lingkungan kerja apabila dilaksanakan secara simultan (bersama-sama) maupun secara parsial (sendiri-sendiri) adalah signifikan signifikan terhadap kinerja proyek di Kota Palangka Raya
Analisa Ekonomi Proyek Pada Pembangunan Palangka Raya Mall
No full textBangunan memegang peranan penting dalam kehidupan masyarakat dan sering kali mempengaruhi suasana hidup bagi setiap individu. Sebagian besar dari kehidupan manusia berada di sekitar atau di dalam bangunan, seperti perumahan, kantor-kantor, tempat-tempat pendidikan, pabrik-pabrik, rumah sakit, jembatan dan sebagainya. Pengaruh yang sedemikian luas itu mengakibatkan sektor bangunan memegang peranan penting dalam meningkatkan kesejahteraan dan perekonomian negara. Tujuan dari penelitian ini adalah untuk menganalisa besarnya investasi yang dikeluarkan untuk pembangunan Gedung Palangka Raya Mall, apakah akan memberikan keuntungan bagi investor dan pemerintah daerah. Pengumpulan data diperoleh dari wawancara (interview) yang kompeten dan pengamatan (observation), juga dari buku-buku, jurnal, dan literatur yang relevan. Hasil Dari hasil perhitungan yang ada, biaya pembangunan dalam waktu hampir 7 tahun tahun akan BEP (break even point), dan ini sangat menguntungkan bagi investor sehingga dengan sisa umur bangunan adalah keuntungan bagi investor dan karena tanah yang digunakan adalah tanah milik pemerintah daerah provinsi, maka setelah habis masa pinjam 40 tahun akan dikembalikan kepada pemerintah provinsi beserta bangunannya, hal ini pun menjadi keuntungan bagi pemerintah daerah. Untuk itu disarankan, bangunan yang ada sudah cukup memadai, sebaiknya perlu didukung dengan fasilitas dan pelayanan yang baik. Sebaiknya parkir diatur sedemikian rupa sehingga pengunjung merasa nyaman dan tidak was-was saat meninggalkan kendaraan di tempat parkir
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
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
