Spectral morphisms, K-theory, and stable ranks [PDF]

open access: yes, 2009
We give a brief account of the interplay between spectral morphisms, K-theory, and stable ranks in the context of Banach algebras.Comment: 12 pages; to appear in the Proceedings of the Workshop on Noncommutative Geometry (Fields Institute, Toronto ...

Business Collective Action: An Integrative Review and Framework

open access: yesJournal of Management Studies, EarlyView.
Abstract Business collective action (BCA) has long been a topic of interest to management scholars. However, our theoretical understanding of this important phenomenon has been hindered by its fragmented development in the literature. To address this shortcoming, we conduct a comprehensive review of BCA across a wide range of disciplines in management,

Unpacking Merit, Fit, and Diversity: A Multifaceted Framework to Academic Gatekeeping in Social Sciences at U.S. R1 Research Universities

open access: yesSociological Inquiry, EarlyView.
This study draws on interviews with 50 sociology and business professors across two private and five public American universities, and proposes a novel “Merit‐Fit‐Diversit” framework to show how narratives of merit, fit, and diversity emerge at different evaluation stages of tenure‐track job candidates. The evaluation produces inequality because: merit

Nonself-adjoint semicrossed products by abelian semigroups

open access: yes, 2011
Let $\mathcal{S}$ be the semigroup $\mathcal{S}=\sum^{\oplus k}_{i=1}\Sc{S}_i$, where for each $i\in I$, $\mathcal{S}_i$ is a countable subsemigroup of the additive semigroup $\B{R}_+$ containing 0.

Co‐Designing a Sensory Support Intervention for Older Adults With Hearing and Vision Impairment Living in Australian Home Care Settings

open access: yesHealth Expectations, Volume 28, Issue 6, December 2025.
ABSTRACT Background Home care services help older adults remain living independently in their own homes. Approximately 70% of home care recipients have hearing and/or vision impairments, and 20% likely have cognitive impairments. A home‐based hearing and vision intervention (SENSE‐Cog), incorporating impairment identification and correction, device and

SARS‐CoV‐2 Nucleocapsid Protein Does Not Induce Inflammation in Endothelial Cells or Monocytes

open access: yesThe FASEB Journal, Volume 39, Issue 20, 31 October 2025.
The SARS‐CoV‐2 nucleocapsid (N) protein was thought to trigger inflammation in endothelial cells and monocytes. We found that these effects were largely caused by trace endotoxin contamination in the recombinant N‐protein. When endotoxin was neutralized or removed, N‐protein no longer induced inflammation in endothelial cells or monocytes. Our findings

Branch Line Couplers With Small Size and Harmonic Suppression Based on Non-Periodic Step Impedance Shunt Stub (SISS) Loaded Lines

open access: yesIEEE Access, 2020
This paper presents branch line couplers with compact size and harmonic suppression based on non-periodic reactively loaded artificial lines. The reactive loading elements of the lines are step impedance shunt stubs (SISSs).
