In order to improve the energy efficiency of cognitive wireless sensor network, this paper introduces threshold-sensitive energy efficient sensor network (TEEN) routing protocol into cognitive wireless sensor network. To make routing and spectrum more stable, this paper presents advanced threshold-sensitive energy efficient sensor network (A-TEEN), which is the optimization of TEEN. A-TEEN opti...

BACKGROUND Teenage motherhood and smoking have important health implications for youth in the United States and globally, but the link between teen childbearing and subsequent smoking is inadequately understood. The selection of disadvantaged young women into early childbearing and smoking may explain higher smoking levels among teen mothers, but teen motherhood may also shape subsequent smokin...

While a review of the literature reveals a set of accepted standards for quality teen space design, this paper seeks to determine if public library teen spaces currently succeed in meeting these standards.

In an effort to lower teen pregnancy rates, several states have enacted policies requiring abstinence-based sex education. In this study, we utilize a difference-in-differences research design to analyze the causal effects of state-level sex education policies from 2000-2011 on variou...
