Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.     

Imagining transformative spaces: the personal–political sites of community archives

Although much has been written about formal archival spaces, little scholarship has addressed the physical spaces of community archives. This paper asks: How do community members imagine the physical spaces that steward identity-based community archives? Based on focus groups with more than 54 community archives users at five different community archives sites across Southern California, this paper examines how members of marginalized communities conceive of the physical space inhabited by community archives representing their communities. The sites explored range from a prominent location on a university campus, to storefronts, strip malls, and small cinderblock buildings. Yet across sites, users spoke about community archives spaces as symbolic and affectively moving locations. Many users described their community archives site as a “home-away-from-home,” marked by intergenerational dialog and a profound sense of belonging. For other users, community archives sites were described as “politically generative spaces” which foster dialog and debate about identity, representation, and activism and enable the community to envision its future. And yet, while the very existence of community archives is political, many participants felt that the full political potential of these sites is not yet realized. By listening to the voices of the communities represented and served by community archives, our research both indicates that a shift is warranted in archival metaphors of space and reveals how community archives are personally and politically transformative spaces for the communities they represent and serve.     

Exploring the everyday realities of grass-roots football coaching: towards a relational perspective

While scholars have increasingly engaged with the (micro)political and emotional experiences of coaches in professional and semi-professional football, little attention has been given to grass-roots coaches’ understandings of these issues. The aim of this paper is to outline one possible research agenda that could contribute to the development of a rich and increasingly nuanced understanding of the everyday realities of being a grass-roots football coach. In particular, we consider (volunteer) coaches’ participation in grass-roots football to be an inherently relational endeavour. Following the presentation of a creative fiction that is based upon our shared experiences of being grass-roots football coaches, we then illustrate how relational thinking might be productively applied to exploring the social, (micro)political and emotional features of grass-roots football coaching.     

On the temporal and behavioural consistency of pre-performance routines: an intra-individual analysis of elite basketball players' free throw shooting accuracy

The effectiveness of pre-performance routines on skilled performance in a self-paced skill has yet to be verified. In this study, we examine the importance of temporal and behavioural consistency in these routines. The duration and specific pattern of behaviours exhibited before each free throw (n = 284) were observed during 14 National Basketball Association play-off games. An intra-individual standardized score was calculated for each shot's duration. Each player's dominant behavioural routine was identified and each shot was classified as "sequence followed" or "sequence not followed". No difference was observed in the success rates of shots associated with brief, long, and regular duration routines (P > 0.05). However, players were more successful when they followed their dominant behavioural sequence (83.77% success) than when they deviated from their specific behavioural pattern (71.43% success) (P < 0.05). The findings are interpreted in light of relevant theory and implications for practice are discussed.     

Reception of Stuart Hall in the Korean intellectual field

After Stuart Hall’s death in 2014, Korean newspapers ran detailed obituaries praising him as an influential British intellectual figure. The broad media attention appears to be unusual, given that he maintained a relatively unknown presence in the Korean cultural fields compared with other theorists. This work examines how and in which context Hall’s writings have been cited, or not cited, and emphasized in the Korean cultural studies. The incorporation of Hall’s writings into the resources of the academic field entangled him in scholarly rituals of parochial citations and applications, resulting in the fragmentation and de-contextualization of Hall’s overall problem. The selective focus on and occasional absence of certain aspects among his intellectual and political legacies may demonstrate how imported British cultural studies have, or not yet, been indigenized and localized in Korean cultural and political contexts.     

I'm Going to Instagram It! An Analysis of Athlete Self-Presentation on Instagram

Using Goffman's notions of self-presentation and gender displays, the following study examines the Instagram feeds of 27 professional athletes to determine how athletes are using the visual social media site for self-presentation. A mixed methods approach examined the photographs and captions to determine what behaviors and themes emerged. Through content analysis, the self-presentation styles of athletes of both genders, as well as the main differences between them were examined, and significant differences emerged that confirmed the previously established gender norms. Through textual analysis, findings with respect to captions align with previous research on athlete self-presentation on social media. Theoretical and practical implications, as well as directions for future research are discussed.     

Collagen-based brain microvasculature model in vitro using three-dimensional printed template

We present an engineered three-dimensional (3D) in vitro brain microvasculature system embedded within the bulk of a collagen matrix. To create a hydrogel template for the functional brain microvascular structure, we fabricated an array of microchannels made of collagen I using microneedles and a 3D printed frame. By culturing mouse brain endothelial cells (bEnd.3) on the luminal surface of cylindrical collagen microchannels, we reconstructed an array of brain microvasculature in vitro with circular cross-sections. We characterized the barrier function of our brain microvasculature by measuring transendothelial permeability of 40 kDa fluorescein isothiocyanate-dextran (Stoke''s radius of ∼4.5 nm), based on an analytical model. The transendothelial permeability decreased significantly over 3 weeks of culture. We also present the disruption of the barrier function with a hyperosmotic mannitol as well as a subsequent recovery over 4 days. Our brain microvasculature model in vitro, consisting of system-in-hydrogel combined with the widely emerging 3D printing technique, can serve as a useful tool not only for fundamental studies associated with blood-brain barrier in physiological and pathological settings but also for pharmaceutical applications.     

Development and implementation of a three-dimensional (3D) printing elective course for health science students

Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.     

Film scenes in interdisciplinary education: teaching the Internet of Things*

The Internet of Things (IoT) is gaining importance in education owing to its rapid development. This study addresses the importance of interdisciplinary education between technology and the humanities. The use of films as a teaching resource is suitable for interdisciplinary education because films represent creative forecasts and predictions on future human society, helping the public realize what could occur in the future. By utilizing films in instruction, students can be trained to understand the three key functions of IoT and acquire the ability to develop creative applications of IoT. An IoT teaching model using the films Minority Report (2002), Big Hero 6 (2014), Iron Man 3 (2013), Her (2013), and Transcendence (2014), all of which depict various applications of IoT that could be helpful in the teaching of the functions and concepts of IoT, is suggested; an interdisciplinary class is carried out for 15 weeks following the model. The effectiveness of the class is measured using quantitative analysis, qualitative analysis, and reflection journals. The findings show that students developed interdisciplinary capacity through education using films.
