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
Global Impact of COVID-19 on Mental Health of Teachers
Get PDFSudden outbreak of the COVID-19 in 2020 had a global impact and threw the world into panic. Schools were shut down and lockdowns were enforced to obey the pandemic guidelines for safety. Teachers were forced to think outside the box and find alternative ways to teach students remotely relying heavily on technology. Teachers, students, parents, and administrators had to endure significant changes while transitioning from in class to remote instruction. These abrupt changes took a toll on their mental health as they were trying to figure out how to navigate and adapt to the changes. Since the pandemic, several studies have been conducted to examine its impact on mental health of teachers around the world. However, very few have focused on the universal factors that contributed to mental stress of teachers around the world. This paper reviews studies from different countries and highlights the most common factors that led to the mental stress of teachers during the pandemic. After reviewing the literature, three major themes were formed: Increased Workload, Student Teacher Relationship, and Adjusting to New Normal. Suggestions on how to help teachers during future such emergencies are also included. The goal of this paper is to understand how the pandemic impacted the mental health of teachers globally and to provide school administrators, policymakers, and other education stakeholders with information that can support teachers in the event of future such emergencies.

Teachers’ perspectives on the impact of information and communication technologies (ICT) in two early childhood settings in New Zealand
No full textThis research examined teachers’ perspectives on the impact of Information and Communication Technologies (ICT) in two early childhood settings in New Zealand. The research literature explained that in New Zealand there is scarcity of literature about teachers’ perspectives on the impact of different kinds of ICT in early childhood services. Therefore, to explore teachers’ perspectives must be beneficial to enhance our knowledge and for centres and participants to reflect on their practice for further development of the practice. A qualitative case study methodology was employed for this small-scale research. This included an anonymous questionnaire completed by teachers in two preschools and in-depth interviews. This research increases our knowledge about uses and challenges of ICT among early childhood educators. The results of the study showed that the teachers had variable access to training, as some teachers attended professional development courses, whereas others learnt about ICT from their colleagues and family members. The teachers in the study perceived that ICT is valuable for children’s learning. They believed that ICT increased learning opportunities as children used internet websites/Google to search for information about their favourite topics. They commented that ICT helped to make connections with parents/families, which enabled them to contribute to their children’s learning. They highlighted that children used cameras for taking the photos to revisit, check their learning and share it with parents. They commented that ICT offered children opportunities for listening to songs and stories. The study confirmed that teachers used ICT in their teaching practice. The teachers commented that they used ICT for writing learning story observations and for sharing them with parents. They used ICT for reflecting on their teaching practices and for finding more information about children’s favourite topics. They used internet websites for creating the resources and learnt poi dances. The study results revealed that ICT increased ways of communication with parents/families. The study suggests early childhood centres for arranging and supporting teachers for attending professional development related to ICT. It suggests providing the children with opportunities to use ICT along with other curriculum areas. The findings suggest teachers to use ICT for communication with parents
Preservice Teachers’ Perceptions of Using iPads with Students with Learning Disabilities
Get PDFPreservice teachers reflected on their experiences teaching mathematics to ten students using iPads. The students had learning disabilities and were tutored over 5 consecutive weeks. Teachers reflected weekly for 5 weeks then responded to an online open-ended survey regarding their overall teaching experience. Findings suggest that the experience allowed preservice teachers to gain helpful insight, knowledge, and ideas on how to use iPads as an instructional tool
