Simulation Based Model For Canine Distemper Virus In Prey-Predator Dynamics, Mussa A. Stephano

Tanzania Journal of Science

This study investigates the dynamic interactions of a prey-predator ecosystem infected with Canine Distemper Virus (CDV), focusing on predation and disease transmission. A deterministic model, coupled with Monte Carlo simulations (MCS), employed to capture both stochastic variability and environmental fluctuations. The findings indicate that classical prey-predator cycles provide the baseline for population dynamics, but the introduction of CDV and environmental noise fundamentally alters system behavior. Initially, populations exhibit oscillations that gradually stabilize into dynamic equilibria. However, the disease persists within both prey and predator populations, suggesting endemicity rather than extinction. Predation plays a dual role in disease dynamics, while it …

To assess the impact of Mental Health First Aid (MHFA) certification among Filipino …

Revisiting The Quiet Life Hypothesis In The Indonesian Banking Industry, Samuel Sumartoyo, Chaikal Nuryakin

Bulletin of Monetary Economics and Banking

This study explores the Quiet Life Hypothesis (QLH) in different bank groups based on market-dominant and state ownership. The instrumental-variable regression results confirm the quiet life hypothesis at the industry level. At the group level, there is no different tendency to act quiet life between the dominant and non-dominant banks. On the other hand, the State-Owned Banks (SOBs) show a more potent act of quiet life than private banks. While the results for SOB were backed by theory and previous empirical studies, they raised the question of why the private banks conduct such “lazy” behavior.

Do Digital Transformation And Macroeconomic Stability Matter For The Asean's Economic Growth?, Sri Andaiyani, Abdul Bashir, Ichsan Hamidi

Bulletin of Monetary Economics and Banking

This work assesses the association between digital transformation, macroeconomic stability, and economic growth. We employ yearly data from 2010 to 2021 in ASEAN countries. The findings show digital transformation and macroeconomic stability can increase in GDP in the long term. Digital transformation contributes favorably and substantially, while macroeconomic stability negatively and significantly affects economic growth in the short-term. The study reveals causal link between digital transformation and macroeconomic stability, causality from digital transformation to economic growth, and economic growth to macroeconomic stability. This implies that digital transformation is the engine of growth.

From Essays To Embodiment: Reimagining Student-Centered Assessment Through Creative Practice, Rory Bester, Carla Lever, Bongani Kona, Mona Hakimi

Turning Toward Being: The Journal of Ontological Inquiry in Education

This essay explores the experience of implementing podcast-based assessment in ‘Feeling History, Making History,’ a semester-long course at the University of the Western Cape (UWC) in South Africa. The course is designed to cultivate broad-based critical and interdisciplinary skill sets in first-year Humanities students. Through pedagogical reflection across three consecutive iterations of this course, we investigate how creative assessment practices such as podcasting both enabled our students to bring their whole “selves” into the academy and productively challenged our own preconceived notions about effective, decolonial pedagogy.

“The Being Of Being Creative” In Assessment: Learning From The Creative And Performing Arts, Eliana Elkhoury

Turning Toward Being: The Journal of Ontological Inquiry in Education

Assessment design shapes not only what students learn, but who they become as learners. In the era of generative artificial intelligence (GenAI), where information is abundant and recall is easily outsourced, higher education assessment must move beyond memorization and toward authentic tasks that cultivate deeper learning and ontological growth. This conceptual, reflective paper argues that assessment should be grounded in students’ mode of being, rather than restricted to knowing, having, or doing. Drawing on Barnett’s ontology of higher education, Biesta’s subjectification, and Su’s epistemological distinctions, this paper positions assessment as a formative site where agency, ownership, identity, and self-understanding can …

The Being Of The Performer, Alice Marshall

Turning Toward Being: The Journal of Ontological Inquiry in Education

This work presents an autoethnographic, practice-as-research inquiry into Tender Steps (Adaire to Dance, 2024), a dance-for-film grounded in the author’s lived experience of baby loss. Through embodied reflection, the article explores how personal experience becomes a site of inquiry, examining the relationship between the performer’s being and the act of performance. Drawing on phenomenological and performance-based perspectives, it considers how posture, weight, breath, and voice function as embodied knowledge and how meaning is co-constructed through the intersubjective relationship between performer and audience. It reflects on the ethical and emotional implications of making lived experience public within a digitally mediated form …

Cytomegalovirus Associated Enterocolitis And Skin Eruption: A Pediatric Case Misdiagnosed As Acute Appendicitis, Zeynep Busra Balik, Gulsen Akoglu

Journal of Pediatric Infectious Diseases

We present a case of an immunocompetent 2-year-old boy, with cytomegalovirus-associated enterocolitis and petechial skin eruption, initially misdiagnosed as acute appendicitis. Despite abdominal pain, diarrhea and a rash for 15 days, diagnostic laparoscopy revealed no surgical pathology. Dermatological examination identified perifollicular petechiae, leading to a diagnosis of cytomegalovirus infection, which was confirmed by serology. This case emphasizes the importance of considering viral infections in pediatric patients with gastrointestinal and dermatological symptoms. It also highlights the diagnostic value of cutaneous findings in cytomegalovirus infection.

Journal of Early Hearing Detection and Intervention

Despite well-intentioned early hearing detection and intervention (EHDI) programs, parents receiving a newborn hearing loss diagnosis often experience distress, uncertainty, and fear, which can impact their readiness to engage in early intervention. The communication and support provided by clinicians in early hearing detection and intervention play a critical role in helping families navigate emotions, overcome barriers, and actively participate in EHDI programs. The purpose of this scoping review is to advance our knowledge of the following: For parents who have a newborn newly diagnosed with hearing loss, how do the actions/behaviors and communication (or lack thereof) of EHDI providers influence …

Geographic And Sociodemographic Disparities In Early Hearing Detection And Intervention Adherence, Amanda Pavan, Anton Kvit, Michael Van Skiba, Analise Ristic, Kirsten R. Coverstone

Journal of Early Hearing Detection and Intervention

Early identification and intervention are crucial to minimizing impacts of congenital hearing loss. Early Hearing Detection and Intervention (EHDI) programs recommend newborn hearing screening before one month of age and a diagnostic audiologic evaluation before three months for infants who do not pass the screening. However, not all infants meet these benchmarks, as geographic and sociodemographic factors may influence adherence.

Addresses of primary contacts and audiology clinics were geocoded to calculate drive times to the nearest clinic in 10-minute intervals for infants born in Minnesota between 2019 and 2021. Birth location, NICU admittance, and sociodemographic characteristics were also analyzed. Random …
