Most respondents reported encountering negative remarks about pathology, spanning all levels of training and practice. Reactions …

The Role Of Generative Ai In Secondary School Business Education: Insights From Teachers’ Perceptions, Leonard Busuttil, Emanuel Mizzi

International Journal for Business Education

Background/Introduction/Purpose: Generative artificial intelligence (GenAI) has entered classrooms more quickly than the evidence base needed to guide its use, and that evidence base remains concentrated in higher education. Comparatively little is known about secondary school business education, a curricular area that brings together accounting, business studies, economics, financial literacy, marketing, and retail, and in which teachers move between subjects whose epistemological and procedural demands differ considerably. Existing studies also tend to treat business education as a single homogeneous domain, or to examine one of its subjects in isolation. This study addresses that gap by examining how secondary school business education …

Fractured Identities: Military–Civilian Dissonance And The Well-Being Of Women Veterans, Melissa D. Smith

Walden Dissertations and Doctoral Studies

For many women leaving military service, the path to civilian life involves a fundamental renegotiation of identity. Gender-specific pressures, institutional norms, and fractured belonging compound reintegration, yet the lived experiences of women veterans navigating competing identities remain underexplored. The purpose of this phenomenological study was to understand the lived experiences of women veterans at least 5 years postdischarge who struggled with identity dissonance between their military and civilian identities. The study was informed by reculturation theory. Seven women veterans participated in semistructured interviews, and data were analyzed using Braun and Clarke’s thematic analysis, revealing five themes: institutions, culture, and unequal …

Incremental Prognostic Value Of The Triglyceride–Glucose Index Beyond The Grace Score For Predicting 30-Day Major Adverse Cardiovascular Events In Non St-Elevation Myocardial Infarction Patients Undergoing Percutaneous Coronary Intervention, Fathi Zahra, Cut A. Andra, Abdul H. Raynaldo, Andika Sitepu, Hilfan A. P. Lubis, Kamal K. Ilyas

Journal of the Hong Kong College of Cardiology

Background: The Global Registry of Acute Coronary Events (GRACE) score is widely used for risk stratification in patients with non–ST-elevation myocardial infarction (NSTEMI). However, it does not account for metabolic factors such as insulin resistance, which may contribute to residual cardiovascular risk. The triglyceride–glucose (TyG) index has emerged as a simple surrogate marker of insulin resistance with potential prognostic value. This study aimed to evaluate the incremental value of the TyG index beyond the GRACE score for predicting short-term outcomes.
Methods: In this retrospective observational design study, 110 patients with NSTEMI undergoing percutaneous coronary intervention (PCI) at Adam Malik Hospital, …

Beyond Cusp Count: Bicuspid Function In A Quadricuspid Aortic Valve, Aneeq Ahmed, Suhail Khan, Luigia D'Errico

Journal of the Hong Kong College of Cardiology

Quadricuspid aortic valve is a rare congenital anomaly usually associated with regurgitation. A young woman underwent surveillance after cardiovascular magnetic resonance imaging demonstrated four equal cusps in diastole but bicuspid-type systolic opening from fusion of the left and non-coronary cusps. By 2025, eccentric regurgitation was severe on echocardiography and moderate-to-severe on magnetic resonance imaging, with a regurgitant fraction of 31% and mild left ventricular dilatation. Increasing breathlessness and declining peak oxygen uptake prompted multidisciplinary review. Valve replacement with ascending aortic support was recommended, and she was considered suitable for a Ross procedure with personalised external aortic root support.

Pre-Participation Echocardiographic Clue To Anomalous Aortic Origin Of The Left Anterior Descending Artery In An Endurance Athlete, Asterios Deligiannis, Maria Anifanti, Evangelia Kouidi

Journal of the Hong Kong College of Cardiology

Anomalous aortic origin of a coronary artery may remain undetected during standard pre-participation cardiovascular screening. We report a 45-year-old asymptomatic marathon runner with normal physical examination and electrocardiogram. Transthoracic echocardiography showed a retroaortic tubular vascular structure with color flow, prompting coronary computed tomography angiography. Imaging demonstrated anomalous origin of the left anterior descending artery from the right sinus of Valsalva with an interarterial course and a coexisting retroaortic left circumflex artery. Functional and rhythm testing were reassuring. This case illustrates the potential incremental diagnostic value of echocardiography in selected athlete evaluations.

The Gender Gap: Exploring Superintendents’ Perceptions And Experiences In Iowa, Jillian Dotson, Matt Townsley

Journal of Organizational & Educational Leadership

Abstract

The gender gap in the superintendent role continues to plague the educational system across the nation. Female school teachers drastically outnumber female superintendents, which limits the number of women superintendents who are available to serve as mentors. Until women can access superintendent positions in an equitable manner, this gender imbalance will continue. The purpose of this study was to explore current Iowa women superintendents' perceptions and experiences with seeking and operating in the superintendency, and understand their perceptions on the strengths and weaknesses of the mentoring support available for new superintendents. The findings confirm that participants in this study …

Seeing The Line Move Up: Educator Perceptions Of Mastery Experiences As Drivers Of Student Engagement And Persistence In Rural Intervention Programs, Carter J. Baran

Journal of Organizational & Educational Leadership

This study examined how educators in a rural secondary school district describe the influence of mastery experiences on student engagement and persistence within academic intervention programs. Drawing on semi-structured interviews with 18 certified educators (six core content teachers, six elective teachers, and six administrators) and a subsequent focus group conducted in a single rural South Carolina school district, this qualitative analysis extends a larger dissertation study on teacher perceptions of dropout-prevention interventions. Using Bandura's (1986, 1997) social cognitive theory and Astin's (1984, 1999) theory of student involvement as a dual conceptual lens, findings indicate that educators consistently identified visible, incremental …
