Are dairy cows replaced too early? Evidence from a structural model and cow‐level data

American Journal of Agricultural Economics, EarlyView.
Abstract In past analyses of animal replacement decisions, studies have claimed that dairy farms often replace dairy cows too early to be maximizing profits. I estimate a structural model of asset replacement to determine the motives behind early replacement of dairy cows.

Cohesion Without Consensus: Attitudinal Profiles of Social Cohesion in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT Headline indicators of social cohesion in Australia have remained stable in recent years despite rising political polarisation and declining institutional trust worldwide. Yet recent protests and incidents of ethnically and politically motivated violence suggest that cohesion may be under strain. If cohesion is understood not as the pursuit of

Leveraging Metamaterial‐Inspired Wireless Resonator for Reliable Quantitative MRI at 1.5T: Linearity, Bias, and Repeatability Assessment

Advanced Physics Research, EarlyView.
This study designed a nonlinear‐response metamaterial‐inspired wireless resonator (MWR) and systematically evaluated the feasibility of using MWR for quantitative magnetic resonance imaging (qMRI), including T1/T2 mapping, apparent diffusion coefficient, and proton density fat fraction.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Plasma Proteomics Identifies Molecular Signatures and Biomarkers Associated With High Structural Damage in Ankylosing Spondylitis

Arthritis &Rheumatology, EarlyView.
Objective Pathologic bone formation in ankylosing spondylitis (AS) is not fully reflected by systemic inflammation, limiting the utility of markers of inflammation for structural damage assessment. This study aimed to identify plasma protein signatures associated with structural damage severity in AS.
