Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
PENGARUH PENERBANGAN TARIF RENDAH MASKAPAI PENERBANGAN AIRASIA TERHADAP KEPUTUSAN BERKUNJUNG WISATAWAN KE SINGAPURA
No full textSingapura merupakan negara maju yang berada tidak terlalu jauh dari Indonesia. Singapura memiliki kelasnya tersendiri sebagai tujuan wisata. Dengan meningkatnya keinginan wisatawan untuk berlibur ke luar negeri, Singapura menyuguhkan destinasi wisata kelas dunia dan di dalamnya telah dilengkapi dengan akses yang baik dan sarana prasarana yang lengkap. Dengan minat wisatawan yang tinggi, muncul penawaran penerbangan tarif rendah yang memberikan layanan penerbangan dengan harga yang murah dibandingkan dengan maskapai penerbangan full service. Dengan kemudahan yang diberikan, kemungkinan minat wisatawan semakin tinggi untuk mengunjungi Singapura. Penelitian ini bertujuan untuk mengukur pengaruh keberadaan penerbangan tarif rendah dari maskapai AirAsia terhadap keputusan berkunjung wisatawan ke Singapura. Pada penelitian ini peneliti menggunakan metode kuantitatif dengan teknik analisis regresi linear sederhana. Sampel berjumlah 100 orang yang dihitung dengan rumus slovin, dipilih menggunakan teknik purposive sampling. Dari penelitian ini didapatkan hasil bahwa nilai konstanta sebesar 24.653. Sedangkan koefisien regresi b bernilai 0.110, nilai adjust R pada penelitian ini sebesar 0,258, hal itu menandakan bahwa variabel penerbangan tarif rendah mempunyai pengaruh positif terhadap keputusan berkunjung sebesar 0,258 dengan presentase sebesar 25,8%. Artinya, korelasi yang dihasilkan masuk pada kategori rendah,yang berarti wisatawan yang mengunjungi Singapura tidak terpaku oleh penerbangan tarif rendah saja, melainkan wisatawan akan tetap mengunjungi Singapura karena adanya citra yang baik dari Singapura sebagai destinasi wisata dunia. Sehingga dapat ditarik kesimpulan bahwa menggunakan atau pun tidak menggunakan maskapai tarif rendah, wisatawan akan tetap mengunjungi Singapura karena citra dari Singapura sebagai destinasi wisata dunia;--- Singapore is one of the advanced country located near Indonesia, Singapore has it own class as the tourist destination. With the increasing demand of tourist to go abroad, singapore served world class tourist destination and enriched with good access and equipped by complete facilities and infrastructure.With the high tourist interest, appear the offer of low cost carrier that gives low-cost service compared with full service airline. With the ease given, the probabilities of tourist interest get higher to visit singapore. This research objective is to measure the influance of the existence low cost carrier from AirAsia airline towards tourist visitation decision to singapore. On this research using quantittative methods with simple analysis regression linear analysis. The total sample researcher take is 100 people that counted by slovin formula, chosen by sampling purposive technique. From this research obtained the value results of the constant is 24,653, and the regression coefficient b value result is 0,110, adjust the value of R in the research is 0.258, it indicates that a variable low-fare airline has a positive influence about 0.258 with percentage of 25,8%. It means the correlation is generated on the low category, it means that tourist who visit Singapore is not only look for low cost airline, however tourist will visit singapore because the good image from singapore as world class tourist destination. So the conclusion with or without low-cost airline, tourist will visit Singapore because of image as world class tourist destination

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
