Kinematic Features of Voluntary and Involuntary Head Movements in Cervical Dystonia

open access: yesMovement Disorders, EarlyView.
Abstract Background Cervical dystonia (CD) has a varied motor presentation, combining abnormal postures with complex involuntary head movements. Classification of these motor patterns remains imprecise, relying on descriptive terminology without robust definitions. Objectives To provide a kinematically‐grounded description of the motor phenomenology of

Using Manganese‐Enhanced DCE‐MRI to Assess Blood‐Cerebrospinal Fluid Barrier Transport

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose We developed a dynamic, heavily T2‐weighted (hT2w) FLAIR protocol to resolve acute Mn2+ transport kinetics, as a proxy for Ca2+, across the choroid plexus (ChP)—cerebrospinal fluid (CSF) interface, in vivo. By quantifying intercompartmental Mn2+ dynamics, and comparing these with Gd‐DOTA, we sought to characterize blood‐CSF‐barrier ...

Reachable Workspace as a Clinical Outcome for Upper Extremity Function: A Narrative Review

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Motion sensing technology can be utilized to capture detailed upper extremity (UE) motion to reconstruct an individual's three‐dimensional (3D) reachable workspace (RWS). The RWS can be quantified as relative surface area (RSA), providing an innovative surrogate measure to assess UE mobility and function.

Linking Environmental Health and Civic Health: An Analysis of Air Pollution and Charitable Giving

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT This study examines the effect of air pollution on charitable giving. We suggest that the burdens associated with poor air quality are associated with a dampening of civic and philanthropic engagement. Analyzing 12 years of county‐level data from the United States with fixed‐effects OLS and instrumental variables regressions, we identify a ...

Opening the Black Box of Nonprofit Reputation and Volunteer Attraction With Supervised Machine Learning

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT With the aim to explore the potential of machine learning for nonprofit research, this article contrasts traditional linear regression with four contemporary supervised machine learning approaches. Concretely, we predict (1) reputation ratings and (2) the total number of volunteers for 4021 non‐profit organizations in the U.S.
