The World Health Organization defines health inequities as differences in health outcomes that are systematic, avoidable, and unjust; and the result of poor social policies, unfair economic arrangements, and bad politics. This volume describes the role that evaluations can play in addressing health inequities. A key focus is on the types of capacities that need to be built to evaluate inequities.Bringing alive these questions around evaluation capacities are theory and practice studies from China, Chile, and India.This volume: Focuses on inequities in evaluation capacity building initiatives. Argues evaluations can be interventions themselves. Explores how evaluations can have influence in addressing inequities. Recognizes that innovations in evaluation capacity experiments are occurring in diverse countries and we have the opportunity to learn from such initiatives. This is the 154th issue in the New Directions for Evaluation series from Jossey-Bass. It is an official publication of the American Evaluation Association.

This SpringerBrief examines the use of cheap commercial passive RFID tags to achieve accurate device-free object-tracking. It presents a sensitive detector, named Twins, which uses a pair of adjacent passive tags to detect uncooperative targets (such as intruders). Twins leverages a newly observed phenomenon called critical state that is caused by interference among passive tags.The author expands on the previous object tracking methods, which are mostly device-based, and reveals a new interference model and their extensive experiments for validation. A prototype implementation of the Twins-based intrusion detection scheme with commercial off-the-shelf reader and tags is also covered in this SpringerBrief.Device-Free Object Tracking Using Passive Tags is designed for researchers and professionals interested in smart sensing, localization, RFID and Internet of Things applications. The content is also useful for advanced-level students studying electrical engineering and computer science.
