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
Erken çocukluk döneminde elektronik medya kullanımı ve ebeveyn rolü.
No full textToday’s children are born and raised in media-saturated environments, surrounded by televisions, computers, tablets, smartphones, and other portable electronic devices. Because these devices have become an indispensable part of everyday life, they have a significant influence on children’s entertainment and leisure, as well as their education. This study therefore examined how early and how much young children (from 0 to 6 years of age) use television, computers, and tablet/smartphones, specifically whether this media usage is directly affected by socio-demographic factors related to the children’s parents (i.e., their education, income, and age), the children themselves (i.e., their age, gender, and the presence and number of siblings), and the media environment in their homes (i.e., the availability of media, parental opinions about media, and regulation of media use). The sample for this study consisted of 412 parents of 0- to 6-year-old children who brought their children to the Social Pediatrics Department of the Faculty of Medicine in Ankara, Turkey, for developmental check-ups. The data for this study were collected through questionnaire that was prepared by the researcher. Statistical analyses were then conducted to evaluate the data. The results of the study show that today’s children start to use electronic media devices at an early age and use them more than expected. And in line with the focus of this study, factors that affect children’s media usage include demographics of both the children and their parents, their parents’ opinions about the effects of electronic media, and parental mediation when the children use media devices.

The impact of a media mediation workshop on parental media mediation for parents of children aged 36-72 months
No full textBu araştırma, 36-72 ay arasındaki çocukların ebeveynlerinin medya aracılığı uygulamalarını geliştirmek amacıyla bir medya aracılığı atölyesinin oluşturulmasını ve bu atölyenin ebeveynlerin medya aracılığı uygulamalarına olan etkisini incelemektedir. Araştırma, karma yöntem stratejilerinden yakınsak paralel desen kullanılarak yürütülmüştür. Nitel veri toplama aşamasında ebeveynlerle görüşmeler yapılmış, araştırmacı günlüğü tutulmuş ve odak grup görüşmelesi gerçekleştirilmiştir. Bu görüşmeler betimsel analiz yöntemiyle incelenmiştir. Nicel veri toplama aşaması ise zayıf deneysel desen kullanılarak, deney ve kontrol gruplu model şeklinde tasarlanmıştır. Ebeveynlerin medya aracılığı uygulamalarını değerlendirmek amacıyla deney ve kontrol gruplarına Erken Çocukluk Ebeveyn Medya Aracılık Ölçeği (EÇEMAÖ) kullanılarak ön test ve son test uygulanmıştır. Nicel sonuçlar, atölyenin deney grubundaki ebeveynlerin medya aracılığı toplam puanlarını istatistiksel olarak anlamlı bir şekilde artırdığını göstermektedir. Kontrol grubundaki ebeveynlerde ise medya aracılığı toplam puanlarında istatistiksel olarak anlamlı bir değişiklik görülmemiştir. EÇEMAÖ alt boyutları incelendiğinde, deney grubu için aktif-destekleyici, kısıtlayıcı-destekleyici, aktif-sınırlayıcı, kısıtlayıcı-sınırlayıcı ve aktif- yorumlayıcı alt boyutunda son test puanları, ön test puanlarına göre istatistiksel olarak anlamlı şekilde yüksek bulunmuştur. Kısıtlayıcı-engelleyici alt boyutunda ise ön test sonuçları, son test sonuçlarına göre istatistiksel olarak anlamlı şekilde yüksek bulunmuştur. Sonuç olarak, nitel ve nicel veriler birbirini desteklemekte ve atölyenin ebeveynlerin medya aracılığı uygulamalarını olumlu yönde geliştirdiği görülmüştür
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
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
