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
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

Teacher sensemaking and implementation fidelity : how do I know what I do until I see what I did
Get PDFThe teacher, as the implementer of a program’s core components, is the most crucial factor that influences the process of educational implementation of any professional development (PD) program. Focusing on how teachers resolve their ambiguity and uncertainties will provide insight regarding how teachers’ participation in PD can influence their decision about implementing the program’s core components (Allen & Penuel, 2015). The purpose of this research is to explore how science teachers’ sensemaking processes influence implementation fidelity of a PD program that emphasizes reform-oriented instructional approaches. The main research question is, how does science teacher sense-making influence implementation fidelity?
Using qualitative case study and numerous data resources (observation of PD, survey, classroom observation and rating, interview, self-report, and artifacts collection) the research revealed six common triggers of teacher sensemaking instances of the program’s core components shared by all teacher participants. They are: the value of PD in their classroom, their emotion regarding the implementation of the core components, the relevance of the PD program to students’ needs, the relevance of PD to state standards, the implementation network that operates within school, and time constraints. The triggers of teacher sensemaking instances that arise only on the low fidelity implementers are: the abundance of information gained from professional learning experiences, lack of clarity about roles and responsibilities to implement the core components, lack of clarity in the setting and environment for implementation, and lack of success measures for implementation. On the other hand, sensemaking of the high-fidelity implementers is focusing on: availability and accessibility to instructional resources, accessibility of the experts, their current progression toward establishing a student-centered classroom, and availability of planning time during the PD.
The research also identifies four types of teachers’ implementation orientation as they make sense of the PD program. They are, (i) passive distributive, (ii) critical evaluative, (iii) creative emergent, and (iv) transformative. The research found that teacher sensemaking of PD is interconnected with their implementation. Thus, to study teacher sensemaking is not only to focus on how teachers make sense of the PD program, but also to study how they implement the reform-oriented program in the classroom.Science, Technology, Engineering, and Mathematics Educatio
Sequential GBB and Pictet-Spengler Reactions for the Synthesis of Novel Polyheterocyclics
Get PDFOver the last twenty years, the Groebke-Blackburn-Bienaymé (GBB) reaction has emerged as a powerful multicomponent reaction to access various nitrogen-based heterocycles that have potential biological activities. In this works, the three-component reactions of indole 3-carbaldehydes with suitable isocyanides and aromatic amines afford the GBB adducts that then further react with aldehydes for the regio-selective Pictet-Spengler (PS) reaction to afford seven-member instead of other ring-size polyheterocyclic compounds. The product structures were confirmed by x-ray single crystal analysis. Both the GBB and PS reactions went smoothly to afford the product analogs with variations of X, R1 and R2
