Learning effectiveness of clinical anatomy and practical spine surgery skills using a new VR-based training platform
No full textIntroduction: As medical education becomes more complex, the demand for advanced teaching and training methods has grown. Technological advancements have opened up new possibilities, particularly in the realm of virtual reality (VR) simulations for training. Research Question: Our prospective, randomized pilot study aims to assess whether a novel VR-based 3D training platform can effectively teach the knowledge and skills needed for complex spinal surgery, specifically pedicle screw placement. Material and MethodsWe enrolled 25 participants who received either a traditional lecture (control group, n=11) or a VR lecture with identical content featuring 3D/VR anatomical models (VR group, n=14). The VR group also underwent VR simulation for pedicle screw placement. We evaluated their learning through a quiz, a practical skills test, and selfassessment questionnaires. Results: In the theory multiple-choice test, the contral group scored an average of 69% (range 53-87%, SD 0.10), while the VR group scored 66% (range 47-87%, SD 0.11) (p=0.692, independent sample t-test).For the practical DOPS test (pedicle screw placement), the average score was 2.4 points (n=25; range 1-4). The VR group on average scored 2.9 points compared to the control (2 points) (p=0.134). Discussion and Conclusion Our study indicates that teaching with a new 3D VR training tool yields results comparable to traditional methods in terms of knowledge retention. This research supports the platform's effectiveness as an educational resource. Importantly, trainees can apply VR-acquired knowledge to real surgical procedures, which are well-received
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
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
Simulated patients and stereotypes – How to deal with diversity in human simulation
No full textBackground
Stereotypes reduce and generalize information into (assumed) group characteristics. This simplification leads to behaviours, appearances and traits being attributed to group members, even when not true for the individual person. Medical education, including formats with simulated patients, too often relies on assumed prototypical (“classic”) but really stereotypical case scenarios in formation and assessment of medical competencies. Though based on the noble didactic idea that circumstantial information would distract learners from a targeted learning objective, or likewise, distract examinees from the focus of the assessment task, it still means that different groups of society are inadequately represented in the curriculum. It seems that so far diversity issues receive little attention at an institutional and curricular level throughout medical schools and academic hospitals (Zanting et al. 2020). At the same time, SP-programs are reaching their limits in accommodating diversity in their current constitution.
Nonetheless, the possibilities of better addressing diversity issues at a curricular level are manifold (Dogra et al. 2009), especially when thinking about the design of role scripts as well as the casting and staffing of SPs. Their function in this matter should not be underestimated (Vora et al. 2021, Picketts et al. 2021, Paroz et al. 2016, Miller et al. 2021). Carefully chosen simulations with diversely designed roles and selection of SPs can reflect social diversity and provide access to the topic of diversity among students.
Objectives
After the workshop, participants will be able to ...
... explain the relevance of diversity for working with SPs in health professions education.
... reflect on their own SP program in terms of diversity with regard to staff, SP-pool and role scripts.
... optimize their work within the SP-program so that they better consider diversity when designing cases and assigning SPs to roles.
... create and revise case scripts that consider aspects of diversity in a non-stereotypical way.
Target Audience
The workshop is intended for all SP-trainers, managers and staff of SP-programs, simulated patients and lecturers working with SPs in teaching or assessment in health professions education. Previous experience with diversity as a topic is not required but SP methodology should be well-known.
Description
In this 3-hour workshop we would like to address the topic of diversity in everyday work with SPs. In particular, SPs representing stereotypical patient roles in teaching and assessments is considered. After a short input, we will together reflect on how to deal with diversity in creating cases and assigning SPs, using concrete SP-scripts as material. At the end, the reflection on developed processes and criteria will be merged into concrete and practical instructions for the creation of case scenarios or revision of already existing simulations. The goal for the participants is to question and reflect on their current working methods with regard to diversity and, at the same time, to take home concrete suggestions in order to represent diversity adequately in the future.
Participants will receive literature and preparatory information in advance that will be revisited later in the workshop. It is also requested to bring two SP scripts from the own institution; one that assumedly takes diversity aspects well into account and one for improvement. Please consider your institution’s regulations for disclosing cases to third parties, especially when bringing assessment material
