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

T.A 2019/2020. Populasi pada penelitian adalah seluruh siswa kelas VII yang
terdiri dari tiga kelas yang berjumlah 69 siswa. Teknik pengambilan sampel yaitu
random sampling sehingga ditetapkan sampel yang digunakan adalah kelas VII A
dengan jumlah siswa sebanyak 24 siswa sebagai kelas eksperimen 1 dan kelas
VII C yangberjumlah 24 siswa sebagai kelas eksperimen 2. Instrumen
penelitianmenggunakan tes tertulis berbentuk uraian, dimana sal kemampuan awal
matematika siswa berjumlah 5 soal dan soal kemampuan kognitif siswa berjumlah
6 soal. Dari hasil analisis data tes di kelas eksperimen 1 diperoleh mean 83,67 dan
untuk data tes di kelas eksperimen 2 diperoleh mean 74,125. Penelitian
menggunakan uji liliefors untuk mengetahui normalitas data hasil belajar.
Pengujian hipotesis dilakukan menggunakan uji Ancova.Dari data perhitungan
hipotesis didapat Fhitung> Ftabel, yaitu 7,384 > 2,00 maka H0 ditolak. Karena H0
ditolak, berarti terdapat perbedaan signifikan pada kemampuan kognitif siswa,
dan dengan sig < 0,05, dimana 0,009 < 0,05 maka H0 ditolak. Maka dapat
disimpulkan bahwa pada tingkat kepercayaan 95% terdapat pengaruh perbedaan
model pembelajaran terhadap kemampuan kognitif siswa
A dark consequence of developmental dyslexia: discrimination of mirror images is not automatized
No full textReading is a cultural activity too recent in the history of the humankind to be en- crypted in the human genome but, paradoxically, some people fail to achieve fluent reading, despite adequate instruction and no sensorial or general cognitive deficits that could explain such specific difficulty. Intensive research has been devoted to the neurocognitive mecha- nisms of reading and the putative differences related to this specific developmental reading disorder or dyslexia. Much research has focused on the relation between literacy and oral lan- guage but reading is also an intensive visual activity that requires specific adaptations of the visual ventral system, including the suppression of mirror invariance (the perceptual bias by which one stimulus and its lateral reflection or mirror image, e.g., d and b, are processed as equivalent percepts). Interestingly, reversal errors (e.g., confusing d with b) have long been documented in dyslexia. In the present paper, we review the available evidence regarding mir- ror-image processing in dyslexic children, taking into account the methodological aspects and shortcomings of prior studies. We also revisit our findings with typically-developing children (preliterate children and 1st-grade beginning readers) and adults (illiterate, ex-illiterate, and schooled literate), and dyslexic children and their two control groups (of chronological age, and of reading level). Our research suggests that dyslexic readers fail to acquire the automatic changes promoted by literacy acquisition outside the written domain. More specifically, we argue that mirror-image discrimination, which is triggered by learning to read and occurs au- tomatically in the course of visual object recognition in typically-developing readers, may ne- ver become automatized in dyslexic readers
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
