... The following sections present research opportunities identified by the committee and drawn from plenary presentations and discussions in breakout sessions of the workshop, along with associated implementation challenges, and a list of new technologies for alerts and warnings that are likely to raise additional research questions. RESEARCH OPPORTuNITIES Message Content The CMAS specification provides for 90­character messages and prohibits the inclusion of uniform resource locators (URLs)

... Message Dissemination Segments of the population are becoming increasingly accustomed to receiving mobile text messages, including alerts and warnings, from other individuals, from businesses, and from government agencies. Indeed, there has been some experience with the use of text alerts in munici ­ pal and countywide systems as well as some research looking at the effectiveness of these systems, but there has been no experience with national­scale systems.
From page 48...
... Past research has shown that people respond to alerts and warnings by seeking additional information to confirm the event, determine their risk, and decide on their next action. Following is a list of research questions in the area of information­seeking behavior: • Can the information­seeking behavior of people who receive CMAS alerts be predicted?
From page 49...
... Demographics and Access Although the use of cellular telephones is widespread, not everyone owns, carries, or uses a cell phone, and cell phone service is not available in some sparsely populated areas. The following questions on these topics need further research: • What is the current demographic profile of use of mobile devices in the United States?
From page 50...
... The constrained message context of CMAS places an even greater premium on educating the population in advance about the steps to take to protect themselves, the best places to go for additional information, and ways in which they might assist others. The size and diversity of the populations that will receive CMAS alerts and the diversity of the hazards about which alerts may need to be sent indicate the challenges of developing educational programs with sufficient breadth.
From page 51...
... Before the CMAS program is introduced nationally, pilot programs can be used to determine what messaging is most effective, how CMAS messages can best be coordinated with other alerts and warnings, and so forth. Finally, ongoing research that gathers lessons learned from the early use of CMAS can be used to improve future generations of the program and to inform local, state, and federal officials on best practices for using the system.
From page 52...
... What is the potential for incorporating sensor devices in widely distributed devices such as cell phones to detect and provide more detailed information on events?
