On the nonlocal Fisher-KPP equation: steady states, spreading speed and global bounds
We consider the Fisher-KPP equation with a non-local interaction term. We
establish a condition on the interaction that allows for existence of
non-constant periodic solutions, and prove uniform upper bounds for the
solutions of the Cauchy problem, as well as upper and lower bounds on the
spreading rate of the solutions with compactly supported initial data
The Media Family: Electronic Media in the Lives of Infants, Toddlers, Preschoolers, and Their Parents
Electronic media is a central focus of many very young children's lives, used by parents to help manage busy schedules, keep the peace, and facilitate family routines such as eating, relaxing, and falling asleep, according to a new national study by the Kaiser Family Foundation. Many parents also express satisfaction with the educational benefits of TV and how it can teach positive behaviors.The report, The Media Family: Electronic Media in the Lives of Infants, Toddlers, Preschoolers, and Their Parents, is based on a national survey of 1,051 parents with children age six months to six years old and a series of focus groups across the country
