"Valid and reliable measurement of media and communication exposure is crucial for communication science, psychology, political science, sociology, pedagogy, economics, and law, and the practitioners in media, communication, and information. At the same time, this is a wicked problem for which there ... are no simple solutions. That was never the case, but in today's digital and abundant media landscape it is even more difficult. The book discusses the ways in which media and communication exposure can be conceptualized, operationalized, and measured. Methods examined include self-reports, recall, recognition, ecological momentary assessment, think aloud, digital traces, data donation, human observation, eye-tracking, EEG, fMRI, heart rate, and skin conductance, their pros and cons, complexities, and performance. The book concludes with recommendations for the application and further development of these methods, as well as an extensive bibliography with references to in-depth insights into specific aspects of media exposure measurement."

"There is no “one size fits all” approach to digital contact tracing technologies (DCTT). Technology design should not be static, but it should be capable of evolving depending upon local conditions, new evidence, and changing preferences and priorities. Technology companies alone should not con ... trol the terms, conditions, or capabilities of DCTT, nor should they presume to know what is acceptable to members of the public. DCTT should be designed to have a base set of features that protect privacy, with layers of additional capabilities that users may choose to activate. An initial default should be that user location data are not shared, but users should be provided with easy mechanisms and prompts to allow for opting-in to this capability, with encouragement to the public if it is shown to be critical to achieving public health goals. Data collected through DCTT should be made available to public health professionals and to researchers in de-identified form to support population-level epidemiologic analyses." (Summary, page 2) more
