Default Effect in ESG Investment: When a Recommendation Goes a Long Way

Business Strategy and the Environment, EarlyView.
ABSTRACT Individual investors display a positive attitude toward ESG investments but typically fail to act upon it. We report results from a preregistered online experiment testing a default option on 1050 US investors examining the mechanisms driving the effectiveness of default options in promoting ESG investments.

Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control
