Effective family planning methods are shown to save lives, contribute to gender equality, and boost economic development. Mass media communication campaigns in low- and middle-income countries have been effective in increasing contraceptive use, although the strategies that increase the likelihood of success are unclear. The present study uses meta-analyses to uncover the average effect of media campaigns on family planning behaviors in low- and middle-income countries and to examine the effectiveness of two communication strategies: entertainment-education and advertising/public service announcements.

PMAs are difficult to control due to nonlinear dynamics, presenting challenges in system implementation. Despite these challenges, PMAs have great potential as a source of resistance for strength training and rehabilitation.

Culturally appropriate community education on the importance of breast health coupled with the availability of free or low-cost mammography screening services may help improve the use of mammography screening services among Black women. The Avon Foundation Community Patient Navigation Program seeks to fill this need.

A pneumatic muscle actuator (PMA) generated an opposing force (antagonist) to the rotating pulley. One application of such a device is for use in microgravity environments because the PMA is compact, simple, and of relatively small mass (283 g).
