Uncertain Short‐Run Restrictions and Statistically Identified Structural Vector Autoregressions
Journal of Applied Econometrics, EarlyView.ABSTRACT This study proposes a combination of a statistical identification approach with potentially invalid short‐run zero restrictions. The estimator shrinks towards imposed restrictions and stops shrinkage when the data provide evidence against a restriction.

Joint Estimation and Bandwidth Selection in Partially Parametric Models
Journal of Applied Econometrics, EarlyView.ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...

Journal of Clinical Ultrasound, EarlyView.A moderate‐sized femoral neck osteophyte (white arrow) in US (A), anteroposterior CR (B), and MRI (C). Additional osteoarthritis‐related changes (arrowheads) are visible in CR and MR, but not in US. US and CR demonstrated similar moderate diagnostic capability to detect mild hip osteoarthritis and were associated with increased hip pain.

Mapping Multi‐Stakeholder Engagement: A Q Methodology in a Regional Project Management Scenario
Strategic Change, EarlyView.ABSTRACT Research on project management describes the essence of projects involving multiple stakeholders, stressing the value derived from diverse work practices. However, this underestimates issues of counterproductive disagreements associated with diverse groups participating in a project.

Prodromal Lewy Body Symptoms and α‐Synuclein Seeding in Idiopathic Olfactory Dysfunction
Movement Disorders Clinical Practice, EarlyView.Abstract Background Early identification of pathological α‐synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease‐modifying treatments. Objectives We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory ...

On the Mean‐Field Limit of Consensus‐Based Methods
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Consensus‐based optimization (CBO) employs a swarm of particles evolving as a system of stochastic differential equations (SDEs). Recently, it has been adapted to yield a derivative free sampling method referred to as consensus‐based sampling (CBS). In this paper, we investigate the “mean‐field limit” of a class of consensus methods, including
