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
PEMANFAATAN FITOPLANKTON Spirulina platensis yang KAYA Docosahexaenoic acid (DHA) dan Eicosapentaenoic acid (EPA) UNTUK FORTIFIKASI PERMEN JELLY
No full textPenelitian ini mengenai pembuatan permen jelly bergizi tinggi yang kaya akan DHA dan EPA yang berasal dari fitoplankton Spirulina platensis. Dalam penelitian ini dilakukan kultivasi fitoplankton Spirulina platensis untuk memperoleh biomassa yang akan difortifikasi kedalam permen jelly. Sebelum difortifikasi kedalam permen terlebih dahulu dilakukan analisis kadar DHA dan EPA pada Spirulina platensis serta pembuatan formula mikroenkapsul dengan berbagai variasi konsentrasi penyalut untuk melihat formula mikroenkapsul terbaik. Dari hasil analisis diperoleh kadar DHA dan EPA berturut-turut sebesar 144,866 mg/g berat kering dan 662,141 mg/g berat kering. Hasil formulasi mikroenkapsul diperoleh mikroenkapsul K2 yang jadi formula terbaik. Selanjutnya dilakukan pembuatan permen jelly dengan memberikan tambahan fitoplankton Spirulina platensis untuk permen fitoplankton dan tanpa penambahan fitoplankton sebagai permen kontrol. Untuk mengetahui kualitas permen maka dilakukan beberapa analisis yakni analisis proksimat, analisis gula reduksi, analisis kandungan DHA dan EPA permen, uji organoleptik dan uji in-vivo. Dari keseluruhan analisis yang dilakukan, secara umum dapat disimpulkan bahwa kualitas permen yang difortifikasi Spirulina platensis jauh lebih baik jika dibandingkan permen kontrol, kedua jenis permen yang telah diproduksi aman dikonsumsi dan secara umum telah memenuhi syarat mutu permen berdasarkan standar SNI 3547-2-2008 dan nutrition data kecuali kadar airnya yang masih berlebih
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
Handover Management for Real-time Application over Multi-homed Broadband Wireless Access Networks
No full textVertical Handover Management for VoIP Session over Brodband Wireless Networks
Full text linkToday, wireless LAN (IEEE802.11g/n) has been the dominant wireless network that can provide high data rates in a \ud
limited coverage area. While emerging mobile WiMAX (IEEE802.16e) can provide a wireless broadband access to \ud
mobile users in a wide coverage area. These two different technolgies will co-exist while complementing each other in \ud
some regions, hence, a mobile node (MN) with dual interfaces traverses and executes many handovers (HOs) between \ud
802.11g and 802.16e. Meanwhile, there is a huge demand for Voice over IP (VoIP) service over wireless networks. \ud
However, VoIP is a delay and loss sensitive application, hence, VoIP session is more likely to be deteriorated during \ud
HO between 802.11g and 802.16e. In order to maintain quality of VoIP session during HO, we proposed Vertical \ud
Handover Management (VHM) for VoIP session that focuses on HO initiation and decision strategy according to the \ud
wireless link condition and congestion state of wireless networks. The VHM exploits request to send (RTS) retries and \ud
round trip time (RTT) between an MN and an access point in an 802.11g interface as well as a carrier to interference \ud
noise ration (CINR) level and MN???s queue length of an 802.16e interface as HO triggers. We then conducted simulation \ud
experiments to evaluate the effectiveness of our proposed VHM using QualNet 4.5. Our simulation results show that \ud
our proposed VHM can preserve the quality of VoIP session during such HO
