Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Firms are experiencing mounting pressure to report their environmental impact. Rather than disclosing their actual performance, however, some are engaging in unethical business (i.e., greenwashing) practices. Prior studies have contributed significantly to the greenwashing literature from varied perspectives, but a comprehensive understanding ...

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Maladaptive exercise includes excessive, compulsive, or compensatory exercise and is a common eating‐disorder (ED) symptom associated with increased severity, slower rates‐of‐recovery, and faster rates‐of‐relapse. Affect‐regulation theories posit that maladaptive exercise functions to reduce high negative affect (NA), although ...
