Necessary and sufficient conditions are obtained for the Lipschitzian stability of local solutions to finite-dimensional parameterized optimization problems in a very general setting. Properties of prox-regularity of the essential objective function and positive defi-niteness of its coderivative Hessian are the key to these results. A previous(More)
Subgradient mappings have many roles in variational analysis, such as the formulation of optimality conditions and, in the special case of normal cone mappings, the statement and analysis of variational inequalities and related expressions. Central to the study of perturbations of solutions to systems of conditions in which subgradient mappings appear are(More)
Collecting is a normal behavior in childhood and adulthood, while hoarding--the gathering, ordering, and disposal of articles without clear conscious motivation or control--is characterized as the pathologic counterpart of collecting. The literature describing the characteristics of collecting and the theories concerning its underlying mechanisms is(More)
Several recent investigations have suggested that neurobiological similarities may exist between patients with eating disorders and those with depression. We performed polysomnograms for two consecutive nights on nine bulimic and six anorectic patients who had no concomitant diagnosis of endogenous depression. The rapid eye movement (REM) latency, REM(More)
