Hotel Digital Capability: Dimensionality And Measurement, Lingling Fan, Chaowu Xie, Jiangchi Zhang, Songshan Huang, Xuequn Wang

Research outputs 2022 to 2026

While the significance of Hotel Digital Capability (HDC) has been acknowledged in the literature, limited attention has been given to its measurement. This study endeavors to identify the dimensions of HDC and construct a reliable measurement scale. A combined approach of qualitative and quantitative methods across three studies was employed to achieve the research objectives. Study 1, grounded in interviews, delineated HDC as a multidimensional construct encompassing digital basic capability, digital integration capability, digital application capability, and digital optimization capability. Building on the four-factor model identified in Study 1, Study 2 formulated an 18-item scale with robust measurement properties. Additionally, …

To Legitimacy And Beyond: A Reform Agenda To Restore Public Confidence In The Federal Courts, Charles G. Geyh Dec 2023

To Legitimacy And Beyond: A Reform Agenda To Restore Public Confidence In The Federal Courts, Charles G. Geyh

Articles by Maurer Faculty

The article begins by describing he ongoing cycle of anti-court sentiment directed at the federal courts. It situates that cycle in historical context, to the end of showing how independence norms have evolved to constrain more draconian efforts to curb the courts in those cycles. The article then explains why the latest cycle is unusually aggressive and why norms that have protected the judiciary’s independence for generations may be at risk if public skepticism of the courts reaches the point of undermining the judiciary’s perceived legitimacy. Next, the article sorts through the definitional clutter that complicates assessments of whether the …

Novel Anti-Influenza Monoclonal Antibodies, Ozlem Gurses

NYMC Student Theses and Dissertations

There is a continual public threat of influenza virus infections. This is related to viruses evolving in multiple animal reservoirs, making infection prevention in humans difficult to achieve and leading to seasonal epidemics and the semi-regular emergence of pandemics. Novel antibody-based therapies are of great interest to researchers because of a dramatic increase in drug resistant strains of influenza viruses. The identification of cross-reactive and broadly protective monoclonal antibodies targeting the influenza proteins presents a promising prospect for the development of a universal therapy. Although the research related to the monoclonal antibodies targeting the viral internal proteins is limited, multiple …

Beta Cell Primary Cilia Mediate Somatostatin Responsiveness Via Sstr3, Samantha E Adamson, Zipeng A Li, Jing W Hughes Dec 2023

Beta Cell Primary Cilia Mediate Somatostatin Responsiveness Via Sstr3, Samantha E Adamson, Zipeng A Li, Jing W Hughes

2020-Current year OA Pubs

Somatostatin is a paracrine modulator of insulin secretion and beta cell function with pleotropic effects on glucose homeostasis. The mechanism of somatostatin-mediated communication between delta and beta cells is not well-understood, which we address in this study via the ciliary somatostatin receptor 3 (SSTR3). Primary cilia are membrane organelles that act as signaling hubs in islets by virtue of their subcellular location and enrichment in signaling proteins such as G-protein coupled receptors (GPCRs). We show that SSTR3, a ciliary GPCR, mediates somatostatin suppression of insulin secretion in mouse islets. Quantitative analysis of calcium flux using a mouse model of genetically …
