Changing Expectations In Higher Education Post-Pandemic, Gregory R. Mackinnon, Tyler Maclean, Mohamad El Maouch, William Yuan, Zhao Kaibin, Bi Dandan, Marwa Saab

Journal of Global Education and Research

A sample of higher education students in Canada and China was surveyed and interviewed to ascertain any changes in their educational expectations given their experiences with emergency remote teaching during the pandemic. In addition, the instructors of these students were interviewed to corroborate student feedback. The research suggested that students in Canada and China expressed expectations of increased flexibility and improved pedagogy. Whereas Canadian students were overtly demanding of the instructor and the educational system, Chinese students were comparatively subtle in their expectation that the post-pandemic level of support be maintained. The primary concern of the Chinese cohort was a …

Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith

International Journal of Speleology

Tourist activity is widely recognised as a source of cave microclimate disturbance, yet visitor-induced variability is difficult to distinguish from natural environmental fluctuations. The coronavirus pandemic created a natural experiment at Poole’s Cavern, United Kingdom, in which periods of complete closure could be compared with contrasting visitor access regimes. Two years of high resolution temperature records from six monitoring points were analysed. Harmonic regression and a state space model removed deterministic diurnal cycles and lower frequency temperature variability. The remaining residual variability differed systematically among visitor access regimes and between daytime and nighttime conditions. Spectral analysis of the residuals identified …

Time And Money: Patterns Of Nonstandard Work Across The First Year Of Covid-19, Ellen M. Whitehead, Alison Winiarski, Emily Wornell, Justin Schupp

Midwest Social Sciences Journal

The COVID-19 pandemic had a well-documented impact on the formal economy, with the extent of these consequences varying across industries and sociodemographic groups. Less attention has been paid to whether the nonstandard economy, including informal and gig work, mirrored this broader economic fallout. We draw on 2019 and 2020 data from the Survey of Household Economics and Decisionmaking to assess participation in, time spent on, and money earned from nonstandard work across the first year of the pandemic. We find evidence of an overall decline in participation in nonstandard work during this time. However, our results indicate heterogeneous experiences across …

Did Maryland’S All-Payer Global Budget Revenue Model Change Hospital Margins And Revenue Per Discharge? A Difference-In-Differences Analysis Of Maryland And Massachusetts, 2010–2023, Kola Adegoke

Health & Biomedical Sciences Faculty Publications

Background: Maryland implemented an all-payer hospital global budget revenue (GBR) model in 2014 to decouple hospital revenue from volume and improve revenue predictability. This study evaluated whether Maryland’s 2014 GBR implementation was associated with differential changes in hospital total margins, inpatient revenue per discharge, and COVID-period margin volatility relative to Massachusetts.

Methods: A matched hospital-year panel for Maryland and Massachusetts spanning 2010–2023 (2,261 matched observations) was constructed by merging Medicare cost report-based financial measures with provider characteristics using CMS certification identifiers. Two-way fixed-effects difference-in-differences models with hospital and year fixed effects and hospital-clustered standard errors estimated post-2014 changes in outcomes …

Adjusting To Extreme Demand Volatility: A Comparative Analysis Of Air Navigation Service Provider Financial Resilience In The Southern Asia-Pacific, Margaret Arblaster, Gui Lohmann

Research outputs 2022 to 2026

Air navigation service providers fund their operations almost entirely through activity-based user charges, creating a structural dependency between revenue and air traffic volume. When traffic collapses, revenue falls immediately, but the cost base, dominated by specialised labour under fixed-term employment contracts and long-lived capital infrastructure, adjusts slowly, if at all. This paper examines how five corporatised, wholly government-owned air navigation service providers in the southern Asia-Pacific (i.e., Airservices Australia, Airways New Zealand, AirNav Indonesia, NiuSky Pacific in Papua New Guinea, and Fiji Airports) responded to the extreme demand shock of the COVID-19 pandemic and assesses the role of government grants …

Clonal hematopoiesis (CH), an age-related expansion of somatically mutated hematopoietic clones, is associated with increased risk of severe infections including coronavirus disease (COVID)-19, yet the underlying mechanisms remain unclear. Here, we investigated the impact of Dnmt3a deficiency in a murine model of influenza A virus (IAV) pneumonia. Dnmt3a-deficient mice exhibited increased pulmonary viral burden and reduced neutrophil accumulation in IAV-infected lungs despite comparable circulating neutrophil numbers. Functional analyses of neutrophils showed impaired chemotactic migration in vitro, whereas maturation, antimicrobial enzyme content, and metabolic capacity were unchanged. Transcriptomic profiling revealed downregulation of pathways involved in chemotaxis, cytokine signaling, and cellular activation, …

Transnational Social Protections And The Market: Seeking Support From The Global Cruise Industry, Yasmin Y. Ortiga

Research Collection School of Social Sciences

Migration studies have mostly portrayed employers as paternalistic or exploitative, creating the very conditions that make migrants’ lives insecure and unstable. This paper challenges this view by showing how the market can also be an unlikely source of protections, where extractive work conditions co-exist with a certain degree of social support. Drawing on interviews with 45 Filipino cruise workers during the COVID-19 pandemic, I discuss how migrants used a logic of employee rights to claim benefits such as food, housing and insurance. Cruise lines willingly provided such protections, but only while workers maintained active contracts onboard their ships. Rather than …

A Longitudinal Analysis Of Hospital Consumer Evaluation In Virginia, Tulay Akmandor Inac

Health Services Research Dissertations

Suboptimal patient experience signals a need to improve clinical efficacy, patient safety, and healthcare quality. The COVID-19 pandemic intensified hospital resource and staffing demands, reducing hospitals’ capacity to invest in patient experience improvement. Prior studies remain limited because many lack longitudinal structure and organized theoretical models, making temporal inference difficult and weakening analyses of patient experience disparities. To address these limitations, this dissertation incorporates three studies examining patient experience and pandemic-related effects.

In state-level markets comparable to Virginia, limited research has examined longitudinal patient experience trends across regional hospital systems using HCAHPS scores. The first study uses descriptive trend analysis …

Clinicopathologic Spectrum Of Renal Disease In Sars-Cov-2 Infection And Post-Covid-19 Vaccination, Naya Williams, Mohammed S. Razzaque

School of Medicine Publications

Both SARS-CoV-2 infection and COVID-19 vaccination have been associated with renal complications. In the context of SARS-CoV-2 infection, kidney injury is primarily attributed to a complex interplay of systemic immune dysregulation and vascular damage. Severe infection triggers a cytokine-mediated inflammatory response characterized by elevated levels of pro-inflammatory mediators, resulting in systemic hemodynamic instability, increased capillary permeability, and renal hypoperfusion, ultimately leading to acute tubular injury. In addition, virus-induced endothelial activation promotes a prothrombotic state, microvascular injury, and further impairment of renal perfusion. Collectively, these processes converge to produce acute kidney injury (AKI) and, in severe or prolonged cases, may contribute …
