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
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
Sistem Kontrol Suhu Inkubator Telur Berasis Mikrokontroler MenggunakanFuzzy LogicdanPulse-Width Modulation
No full textAbstrak –Inkubator merupakan alat untuk melakukan pemantuan pengeraman menggantikan fungsi dari induk ayam ataupun unggas lainya.Untuk pengeraman induk ayam ataupun unggas lainya membutuhkan suhu ± 36 – 40 derajat celcius.Untuk menjaga suhu agar stabil antara 36 hingga 40 derajat celcius maka diperlukanlah sebuah kontrol yang mampu memenuhi kebutuhan inkubator tersebut. Dirancanglah sebuah alat kontrol suhu untuk inkubator telur sebagai pengganti induk ayam dengan berbasis mikrokontroler sebagai unit proses yang dibantu dengan fuzzy logic dan Pulse-Width Modulation (PWM). dengan menggandalkan sensor SHT11 sebagai pembaca suhu serta kipas dan elemen pemanas sebagai alat untuk menaikkan serta menurunkan suhu. Untuk perancangan, Fuzzy Logic beserta PWM diletakkan pada mikrokontroler sehingga mampu mengendalikan kerja elemen pemanas maupun kipas pendingin. Hasil yang didapat setelah pengujian menggunakan simulasi box yang berukuran 30 x 16 x 24, mikrokonroler yang menggunakan Fuzzy Logic serta PWM mampu mempertahankan suhu stabil antara 36 hingga 40 derajat celcius setelah alat bekerja dalam beberapa waktu.</jats:p
Analysis of Least Significant Bit Method Using Sequential Encoding-Decoding in Steganography Digital Image
No full textThe method of steganography commonly used to hide data or information is Least Significant Bit (LSB) method. One of the relevant research is LSB using sequential Encoding - Decoding by David Pipkorn and Preston Weisbrot. In this research, an analysis of the LSB method using Sequential Encoding - Decoding by doing some testing. The tests are on the aspect of message security using tools StegSpy and enhanced LSB algorithm, testing on image quality by calculating the Peak Signal to Noise Ratio (PSNR) value and see the image histogram, testing on robustness of message by doing some image processing operations on stego image, like cropping, rotating, and etc, and then testing on capacity to check size of cover image and stego image and calculates the maximum size of data that can be hidden. From the testing process, we know that there are deficiencies in the aspects of security, robustness and capacity of a message. And then in this research we try to change the location of messages that are hidden in the image bits, which previous research used the 8th bit of each bytes, changed to the 7th bit. To be able to correct deficiencies in the security aspect. After repairing and testing like before, obtained better results in the security aspect. This can be seen from the image of the enhanced LSB algorithm process, the message is not detected, but unfortunately the image quality is reduced, with the low PSNR value generated
RANCANG BANGUN APLIKASI MOBILE VOTE BERBASIS MOBILE MULTIPLATFORM
No full textAbstrak – Pemungutan suara adalah jawaban yang paling tepat untuk mengambil keputusan berdasarkan tujuan ataupun maksud yang ingin di ambil jawabannya secara cepat, tepat dan berdasarkan keadaan yang sesungguhnya.Hanya saja, pemungutan suara yang saat ini biasa terjadi di masyarakat memiliki berbagai masalah, seperti kecurangan, lamanya proses, banyak nya biaya yang digunakan. Untuk itu dibangunlah sebuah aplikasi pemungutan suara yang mampu menyelesaikan masalah-masalah tersebut, seperti membangun aplikasi mobile vote, dan melihat banyaknya pengguna smartphone di masyarakat pada saat ini, juga memungkinkan pada penelitian ini dibangunlah sebuah aplikasi mobile vote berbasis mobile multiplatform. Aplikasi Mobile Multiplatform adalah aplikasi yang dapat berjalan pada banyak sistem operasai smartphone. Pada penelitian ini aplikasi mobile vote yang dibangun adalah aplikasi dengan pemrograman PHP dan beberapa SDK dari berbagai sistem operasi smartphone.Hasil dari pengujian yang dilakukan terhadap aplikasi yang dibangun menunjukan sistem telah berjalan dengan baik dan sesuai yang diharapkan.</jats:p
