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
(CR48) A Rare Presentation of Upper Airway Obstruction in Infancy with its Surgical Approach
No full textIntroduction:
Undiagnosed oropharyngeal teratomas that are present at birth are challenging to manage, especially in non-tertiary hospitals. Antenatal diagnosis of this disorder is crucial for proper planning for safe delivery as this mass may cause significant airway obstruction, leading to irreversible foetal morbidity and mortality.
Case Presentation:
We report a month-old baby boy who presented with progressive respiratory distress on day 7 of life and was hospitalised on day 15 due to a worsening of respiratory symptoms. Our examination showed a left oropharyngeal mass with obliteration of the pyriform fossa. Magnetic Resonance Imaging (MRI) confirmed the solid parapharyngeal mass with its epicentre at the oropharyngeal, which causes tracheal deviation to the contralateral side and narrowing of the oropharyngeal as well as hypopharyngeal diameter to 1.7cm. Transoral excision of the mass is done under general anaesthesia with uneventful postoperative recovery. Histopathology revealed a mature teratoma and 2 years of follow-up showed no recurrence.
Conclusion:
Teratomas in the head and neck are rare, accounting for 2–9% of all reported teratomas, and they are more uncommon in the oropharyngeal region. Although teratomas are benign tumours, they may be life-threatening because of their location. The rarity of it as the causes of upper airway obstruction in neonates may result in delayed diagnosis and this may result in difficulty during intubation if required. This case report brings forth the atypical clinical presentation and the chosen surgical approach in this infant versus the conventional transcervical approach, while also sharing our experience as a newly established paediatric otorhinolaryngology centre in Malaysia
ANALISIS PENGARUH KEANEKARAGAMAN KOGNITIF (COGNITIVE DIVERSITY) DAN KEPERCAYAAN (TRUST) TERHADAP HASIL KEPUTUSAN STRATEGIS (STRATEGIC DECISION OUTCOMES)
Get PDFSetelah mengamati bahwa sangat pentingnya pengambilan keputusan
stratejik (strategic decision making) perusahaan dengan berbagai faktor yang
mempengaruhi kepada hasil dari keputusan tersebut maka penulis tertarik untuk
menganalisis lebih lanjut tentang topik ini. Peneliti mengedepankan penelitian
terhadap pengaruh keanekaragaman kognitif (cognitive diversity) dengan
kepercayaan (trust) sebagai moderating effect terhadap hasil keputusan strategis
perusahaan berupa komitmen (commitment) dan kualitas keputusan (decision
quality). Oleh karena itu peneliti ini mengambil judul “Analisis Pengaruh
Keanekaragaman Kognitif (Cognitive Diversity) dan Kepercayaan (Trust)
terhadap Hasil Keputusan Strategis (Strategic Decision Outcomes)”dengan studi
kasus pada tim eksekutif perusahaan skala sedang dan besar yang ada di Sumatera
Barat.
Penelitian ini menjadi menarik bagi peneliti selain atas dasar faktor-faktor
yang sudah dijelaskan diatas peneliti ingin menghubungkan antara budaya
Indonesia khususnya budaya Sumatera Barat yang mengedepankan
keanekaragaman dan kepercayaan terhadap hasil dari keputusan strategis
perusahaan.
Penelitian ini merupakan penelitian dasar yang berhubungan dengan
beberapa penelitan sebelumnya yang telah dilakukan pada perusahaan-perusahaan
China Daratan dan AS. Namun pada penelitian ini mencakup wilayah yang
berbeda yaitu Indonesia khususnya Sumatera Barat
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
