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
The personal tutor and tutees' encounters of the personal tutor role: Their lived experiences
Get PDFThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The study investigated the relationship between personal tutor and tutee, perceptions of support encounters and their lived experiences within an undergraduate preregistration nurse education programme.
The personal tutoring system plays a vital role in sustaining nurse learners by being an anchor for their professional and personal development. The tutors monitor progress, support, intervene on the tutees' behalf and act as a confidante. The need for support is especially acute in university based nurse education when the tutees face challenges in clinical practice due to the vocational and professional nature of the course they are undertaking. Yet the meaning of the personal tutoring role is often confusing and serious misunderstandings may exist between tutors and tutees.
The aim of this study is to search for the meamng of personal tutoring by illuminating their lived expenences and encounters. An 'Husserlian' phenomenological approach was taken. A purposive sample of 36 tutors and 44 tutees (9 tutors and 10 tutees were from a Northern university and 27 tutors and 34 tutees from a London university) took part in the study. Each of their experiences were recorded in a 30-45 minutes open-ended taped interview. The findings were analysed by Colaizzi's (1978); Van Manen's (1990) and Cortazzi's (1993) data analysis methods.
The findings revealed a wide variation of encounters on the nature of support and practice. The tutees varied in their readiness to learn, define, discuss and negotiate support. Often they lacked the powers of effective communication skills or the ability to think about their role in the process of negotiating access and support. They then found themselves experiencing a 'sink or swim' phenomenon. They reported a 'parent and child relationship' and attributed problems to a shortfall in the quality of their tutors' interpersonal interactions. Tutees reported positive encounters when they got and felt supported by their tutors. The tutors' data showed that they had an overwhelming feeling of frustration when tutees lacked study skills and presented their personal problems.
Some tutors indicated a high level of empathic understanding for their tutees and showed that they would often 'go an extra mile' to support their tutees. A few other tutors offered very little support or guidance. The essences that were found to be important in the tutor-tutee relationship were: mutual trust, engagement, respect and accepting responsibilities.
The study illuminated the complexity and skill required to be a tutee and a tutor. Tutors individual support styles echoed with the tutees to varying degrees. A positive experience by tutees and tutors was perceived when each had a shared understanding of the support concept.
Therefore, the study has highlighted the need for greater (and arguably formal) guidance to learners on the premises of learning and personal tutor support in the Higher Education context. Conversely, it suggests that benefit might accrue from skill training in personal tutor work for nurse teachers to enable them to better understand students learning needs and skill training for tutees to enable them to be more self-aware of their learning needs., thereby ensuring a more sophisticated support relationship between both tutor and tutee
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
SYNTHESIS OF A SINGLE CRYSTAL OF A NONSTOICHIONETRIC NIOBIUM MONOXIDE
Get PDFNonstoichiometric niobium monoxide (NbOy) powder was synthesized by chemical reaction of Nb2O5 with metal Nb at 1400-1600 °C in the vacuum. A single crystal was further grown from the synthesized powder. Samples were characterized by XRD, SEM, EDAX and EBSD.Исследование выполнено за счет гранта Российского научного фонда (проект № 19-73-20012) в ИХТТ УрО РАН и ОИ (ФТИК)
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
S Colloidal Nanoparticles Stabilized by MPS in Water Solution
Get PDFSelf-assembly of colloidal Ag2S nanoparticles (NPs) was studied in the presence of (3-mercaptopropyl)trimethoxysilane (MPS). Solutions with different molar ratios of Ag2S/MPS were prepared. The appearance of nanoand microtubes was detected. Self-organized NPs were studied with optical microscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and high-resolution transmission electron microscopy (HRTEM). Silicon nuclear magnetic resonance spectroscopy (29Si NMR) was used to study polycondensation of MPS molecules. Geometrical parameters of the nano- and microtubes depended on the molar ratio of Ag2S/MPS. The scheme and mechanism of self-assembly of Ag2S NPs in nanotubes in the presence of MPS were proposed. The effect of MPS on the preservation of the initial stoichiometry of Ag2S NPs was discussed. © 2020 American Chemical Society.The authors are grateful to E. Y. Gerasimov, O. S. Eltsov, and I. D.

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
