Generalized -Type I Univex Functions in Multiobjective Optimization

Abstract

A new class of generalized functions d-ρ-η-θ -type I univex is introduced for a nonsmooth multiobjective programming problem. Based upon these generalized functions, sufficient optimality conditions are established. Weak, strong, converse, and strict converse duality theorems are also derived for Mond-Weir-type multiobjective dual program.

Interventions to control children's screen use and their effect on sleep: A systematic review and meta‐analysis

“…Interventions to reduce screen time in children have been previously investigated (Friedrich, Polet, Schuch, & Wagner, 2014;Maniccia, Davison, Marshall, Manganello, & Dennison, 2011;Marsh, Foley, Wilks, & Maddison, 2014;Ramsey Buchanan et al, 2016;Schmidt et al, 2012;Steeves, Thompson, Bassett, Fitzhugh, & Raynor, 2011;Wahi, Parkin, Beyene, Uleryk, & Birken, 2011;Wu, Sun, He, & Jiang, 2016). Many of these interventions aimed to reduce body mass index (BMI) by addressing sedentary behaviour and used screen time as a proxy for sedentary behaviour.…”
