Living with the Unknown: Intolerance of Uncertainty in Parkinson's Disease
Movement Disorders Clinical Practice, EarlyView.Abstract Background Parkinson's disease (PD) is marked by pervasive uncertainty due to fluctuating motor and non‐motor symptoms, variable treatment response, and an unpredictable clinical course. Intolerance of uncertainty (IU), a tendency to perceive ambiguity as threatening and respond with worry, avoidance, or decisional paralysis, may be ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

From Connections to Actions: When Do Government Ties Matter to Nonprofit Organizational Performance?
Public Administration and Development, EarlyView.ABSTRACT Nonprofit organizations are essential for public service delivery, yet the value of their government ties is contested. This study examines the mechanism that translates these connections into tangible results. We propose that political networking—the deliberate cultivation and use of official relationships—is the critical catalyst.
