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
Computational thinking, informal learning, and makerspace
Full text linkThe continuous advancement of technology has made it a crucial tool across various disciplines. As adaptation to this rapidly progressing field occurred, teaching and learning problem-solving skills are more essential than ever for empowering individuals to succeed across diverse fields. Studies have shown that engaging K-12 students in activities encouraging science, technology, engineering, mathematics (STEM), and computational thinking (CT) are critical for teaching them how to deal with complex problems (Rode, Barkhuus, & Ioannou, 2024; Shu & Huang, 2021). Makerspaces and making activities became popular among researchers and educators due to their potential to advance learning, enhance problem-solving skills, and expose students to STEM. Despite the numerous learning benefits reported by researchers related to makerspace and making activities (Lampe, 2023; Gousie, 2023), little research addressed their effectiveness in promoting learning outcomes among middle-school students. This gap in the literature underlined the importance of conducting a more rigorous study specifically targeting middle-school students to uncover the learning potentials and benefits of this environment in fostering essential skills such as CT.
This research investigated the development of CT skills among middle-school students through project activities in a makerspace learning setting. It proposed a CT framework that described CT as a thought process encompassing problem decomposition, abstraction, and algorithmic thinking. Grounded in constructivism and constructionism, the research engaged middle-school students in programming and physical-computing activities in a makerspace to explore the potential of making in fostering CT skills. It proposed three iv hands-on projects, later reduced to two projects, and a curriculum map that teachers could use to teach CT skills to middle-school students. To answer the research questions, the analysis adapted the design-based research methodology (DBR) and incorporated formative and summative assessment to evaluate the development of CT skills among students.
The researcher carried out a two-day pilot at the university maker space to acquire insight and introduce improvements to the final study. The goal was to ensure that the approach to teaching the content and collecting the data would lead to valuable outcomes. Twenty-five students from local schools were recruited and self-selected to participate in the pilot. The researcher noted numerous areas—such as the study’s time frame, resource allocations, and the group size of students—for improvement. The final research took place at a makerspace in middle school. The participants were forty-nine 8th graders. There were five sessions, each consisting of different activities. In the first session, students took the pre-surveys and participated in a hook activity. Students worked on the maker projects in the subsequent sessions. They completed the post-surveys after the fifth session.
Facilitators collected quantitative data from surveys: students completed n=32 background knowledge and maker activities, n=43 self-report surveys, which consisted of CT disposition, frequency of use, and self-evaluation of maker activity-related knowledge and CT skills for quantitative analysis, and n=14 computational learning (see Appendix H). Educators used rubric (see Appendix A) to collect qualitative and quantitative data from students n=24 to form insight about students` progress during the intervention. The data was transcribed and analyzed using SPASS.
The results from the quantitative and qualitative analysis show that hands-on, project-based learning at makerspace indeed fosters the development of CT skills. Results revealed significant improvements in CT skills, especially in circuit design and programming, using tools like Makey Makey and Arduino. No significant changes were v marked in CT dispositions such as persistence, collaboration, and tolerance for ambiguity among middle school students. Researchers observed slight changes in scores of the frequency of using CT surveys, but only one item achieved a statistically significant improvement. The findings of the computational learning (see Appendix H) survey showed minor numerical improvements or changes in mean scores for some items. However, most were not statistically significant. The qualitative and qualitative findings from the rubric (see Appendix A) captured insight into students’ performance differences between both activities.
The research highlights the value of explicit, intentional, procedural, and collaborative scaffolding techniques to support students\u27 learning and resilience in complex problem-solving tasks. The outcomes emphasize the significance of tailoring activities for middle-school students to CT concepts. However, it is essential to acknowledge that more prolonged, consistent interventions, dynamic scaffolding, and reflective practices are necessary to foster CT skills, disposition, and frequency of use
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
