The clinician sees, almost exclusively, the most severely abused whereas the epidemiologist studies the full range of reported child sexual abuse in a community. The clinician extrapolates from the individual case where dramatic personal experiences like child sexual abuse inevitably seem to explain the occurrence of disorder (particularly when patient and therapist start from the assumption that child sexual abuse deserves primacy), whereas the epidemiologist studying differences in incidence of disorders in a population is drawn to broad sociocultural and environmental influences that explain the bulk of the variation in populations.
A new LTE protocol named LTE Direct is a device-to-device technology enabling the discovery of thousands of devices in the proximity of approximately 500 meters.  Pioneered by Qualcomm , the company has been leading the standardization of this new technology along with other 3GPP participants. LTE Direct offers several advantages over existing proximity solutions including but not limited to Wi-Fi or Bluetooth . One of the most popular use cases for this technology was developed by a New York City based company called Compass. The core feature of proximal discovery among devices included a targeted discount voucher to a nearby device which matched specific interests.  The Compass use case was featured at global conferences and events such as CES 2015, MWC 2015, and said to be extended to many other scenarios including film festivals, theme parks and sporting events. It is claimed [ by whom? ] that the protocol offers less battery drainage and extended range when compared to other proximity solutions.
