A Valued Capability? The Role of Quality in Hospital Acquisition Target Selection

Strategic Change, Volume 34, Issue 6, Page 831-843, November 2025.
ABSTRACT A significant body of existing research focuses on acquisitions and how organizations use them in order to change and grow quickly. While some research has examined the criteria organizations use to select targets for acquisitions, both the context of healthcare and the role of the quality of organizational services have not been well examined.

Hospitals serving high concentrations of patients with dementia are associated with lower mortality rates for patients with dementia

Alzheimer's &Dementia: Behavior &Socioeconomics of Aging, Volume 1, Issue 1, March 2025.
Abstract INTRODUCTION While hospital‐related spending is substantially higher for ADRD populations, it is unknown whether differences exist in the use of hospital services in those hospitals serving high proportions of patients with dementia. METHODS We used 2014–2019 Medicare claims to compare hospitals treating high (321 high dementia concentration ...

Velocity estimation and compensation approach for SFW radar visa IGSS

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper introduces a pioneering velocity estimation technique utilizing the fractional Fourier transform (FrFT) to address these limitations. Leveraging the characteristic of the Doppler signal from a moving target, which manifests as a chirp signal with a rate proportional to the target's velocity, the FrFT is utilized for precise velocity ...

Efficient Signal Processing for Frequency‐Agile Radar With Limited Computational Resources

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This letter designs the transmitted waveform for frequency‐agile radar to transform the velocity‐related phase into a linear phase and, based on this, proposes a fast high‐resolution range profile generation method for frequency‐agile radar that does not require velocity compensation.
