Navigating Errors: Voice Assistants And Aging Users, Bea Marithe V. Pulido

Theses

This study examined how age relates to usability, cognitive load, and affect when using voice-user interfaces (VUIs). VUIs such as Siri, Alexa, and Google Home are increasingly common and allow users to complete tasks through voice commands. While these systems can be convenient and accessible, especially for older adults, they often provide brief or unclear feedback when errors occur, making it difficult for users to understand what went wrong and how to continue the interaction. The current study compared older and younger adults (n = 40) to examine group differences in perceived usability, cognitive load, and affective change during VUI …

Understanding And Supporting Youth Affected By Trauma And Stress, Cara Murray, Anna Gilliam, Jared Hawkins, Christina Pay

All Current Publications

Adults who work with youth are central to creating environments where young people feel safe, supported, and able to succeed. However, some youth have experienced stress, adversity, or trauma that can make it more difficult for them to feel safe, connected, and successful. By learning how to support youth with compassion and consistency, caring adults can help buffer the effects of adversity and promote resilience.

Although insects are fundamental to understanding and conserving global biodiversity, they are vastly understudied. Here, we present a national inventory of Costa Rican insects based upon 3.78 million DNA barcodes representing 152 891 Barcode Index Numbers (BINs, proxies for species) from 28 localities sampled from 2017 to 2023 through the national BioAlfa program of Costa Rica. Although only 3.6% of BINs are linked to Linnean species, barcode-based community analyses revealed strong, consistent ecogeographic structure. Clustering of BIN data using bootstrapped Jaccard distances revealed seven distinct mainland assemblages and a distinct island cluster, shaped primarily by Costa Rica’s mountain ranges, elevation, …

Premarket Clinical Evidence Strength And Recalls Of High-Risk Therapeutic Medical Devices, Maryam Mooghali, Faaizah Arshad, Vinay K Rathi, Kushal T Kadakia, Alexander O Everhart, Joseph S Ross, Sanket S Dhruva

2020-Current year OA Pubs

IMPORTANCE: High-risk medical devices approved through the US Food and Drug Administration (FDA) premarket approval (PMA) pathway may be supported by limited premarket clinical evidence, leaving uncertainties about safety. Whether device, premarket clinical evidence, or regulatory characteristics are associated with subsequent device recalls is unknown.

OBJECTIVE: To examine the association between device, premarket clinical evidence, and regulatory characteristics and serious recalls among high-risk therapeutic devices.

DESIGN AND SETTING: This cross-sectional study reviewed 193 high-risk therapeutic medical devices approved through the FDA's PMA pathway between January 1, 2014, and December 31, 2023. Data were analyzed between August 2025 and December 2025. …

Consequences Of Teacher Violence Among Musicians, Karla María Reynoso Vargas, Basilio Fernández-Morante

Visions of Research in Music Education

This is a standalone work, but it is complementary to the study, “Teacher violence in university music education: An exploration in a Mexican context.” It presents the analysis of emerging information found in 53 stories of victims of teacher violence in university music programs. We incorporated reflections and contributions from students, professionals, and dropouts of music careers in the Mexican Republic, who voluntarily shared their stories. The first category describes the consequences of teacher violence. On one hand, there were effects interpreted as positive, including the activation of achievement orientation, overexertion, and self-demand. It is pointed out that these consequences …

Teacher Violence In University Music Education: An Exploration In The Mexican Context, Karla María Reynoso Vargas, Basilio Fernández-Morante

Visions of Research in Music Education

This article presents the results of an exploratory phenomenological study aimed at identifying expressions of teacher violence in university music training environments in the Mexican context. We analyzed 53 accounts from students, professionals, and dropouts of music degree programs who studied at universities or conservatories across nine Mexican states and voluntarily shared their testimonies through the Mexican Association of Music Psychology (AMEPSIM). We address sociological assumptions about the dynamics of violence, the socio-educational weight of the conservatory tradition and its potential link to the limited application of contemporary pedagogical principles, as well as the normalization of teacher violence. Various forms …

A Sociological Framework For Spatial Analyses Of Institutional Musicking In Conflict Spaces, Carol Frierson-Campbell

Visions of Research in Music Education

This essay presents a framework that brings spatial sociology together with Small’s (1998, 1999) concept of musicking and Born’s (2011, 2012, 2015) Planes of Music Sociality. It was developed as an analytical scheme for an ongoing case study of musicking via the Edward Said National Conservatory of Music (ESNCM), the national music conservatory of Palestine. Small’s notion of musicking reminds music educators that musicking activities communicate meanings beyond the obvious: Individual and collective ideals about relationships with sound, with other people, and with the spaces they inhabit. Born’s conception of musical socialities as four interacting planes goes beyond Small’s ideas …

Teacher Education In The Arts: A Case Study Of Constraint, Standardization, And Resistance, Terry Sefton, Danielle Sirek

Visions of Research in Music Education

In this case study, we explore one course in one Ontario initial teacher education program to examine the intersecting institutional documents and practices that regulate teaching in the arts (dance, drama, music, and visual arts). Using the feminist sociological research approach of institutional ethnography, we identify and trace institutional mechanisms that regulate teaching in the arts and how four women instructors activated or resisted those regulatory practices. Our analysis illuminated tensions between institutional policies and practices, and instructors’ efforts to maintain creativity, ambiguity, and discipline-specific experiential learning in the course. While instructors varied in their pedagogical approaches, over a seven-year …

Competition For All? The Ftc’S Ban On Non-Competes And The More Effective Route In Promoting Competition, Aniqah Nashiat

St. John's Law Review

(Excerpt)

Employment contracts have historically included non-compete agreements, which are restrictive covenants forbidding employees from working “for competitors of their former employer for a certain period of time and over a defined geographic area.” American jurisprudence has always left enforcement of these non-competes to states. In the federal government, Congress has never successfully passed legislation on the per se illegality of non-competes. Instead, President Joe Biden signed an executive order in 2021 aimed at promoting the interests of American workers because companies requiring them to sign non-competes restricted their ability to change jobs. Biden explained that strengthening antitrust laws would …

The Minority Report: When Should Publicly Traded Corporations Be Required To Disclose Material Information To Its Shareholders Under Item 303?, Alicia Mayo

St. John's Law Review

(Excerpt)

Private Securities Enforcement And The Roberts Court, Michael A. Perino

St. John's Law Review

(Excerpt)

Thank you, Judge Lohier, thank you Professor Subotnik, and thank you to everyone who put this scholarship symposium together. I am acutely aware that I am the last panelist, on the last panel, on Friday afternoon, and so, I am going to try my best to keep my comments to the allotted ten minutes.

It is important to keep two key points in mind if we are going to talk about the Roberts Court’s approach to private securities enforcement. First, the Roberts Court contains no securities experts. In fact, except for Lewis F. Powell Jr. and William O. Douglas, …

Utilization Of An Open-Access Markerless Motion Analysis Software For A Biomechanics Movement Analysis Project., Tamra L. Llewellyn, Michael J. Nolan

Educational Practices in Kinesiology

The movement analysis project (MAP) is a common assignment in many undergraduate biomechanics courses. The purpose of this article is to introduce kinesiology educators to an open-source, AI-enabled, markerless software for motion capture, OpenCap, which can be used in MAP and research. This tool is currently being used in an in-person, upper-level, undergraduate biomechanics course where students are required to have taken Anatomy & Physiology. There is very little time, money, or expertise needed to implement this resource. Using 2 iPads on tripods and the OpenCap app and web-based interface, movements can be quickly converted to skeleton visualization and joint …
