One of the main problems of the Russian science-intensive and high technology complex is a huge dependence on imported component base. Meanwhile approaches for its solution used by the Russian Government seems to be insufficient and inefficient especially in the long run. The author discusses an alternative way of development for radio-electronic industry in Russia that is to fund several long-term promising chip production technology of new generation. The results of comparative prognostic calculations for two development scenarios using an intersectoral balance model for science-intensive and high technology complex is provided.

Abstract Detection devices are becoming more wideband, faster scanning and their signal processing capabilities are increasing. In addition, sophisticated jamming devices have become rather powerful. As a consequence, threats to military radio communications have increased such that it is about time to discuss what features future military radio systems should have in order to battle against these increased menaces. This paper fills this gap by considering this problem from the point of view of electronic warfare physics. The result is a set of features that would help in the engagement. Furthermore, it discusses what effects these features have for radio system design. The proposed features add new properties, compared with legacy radios, that require new control functionalities that have to cooperate with old ones as well as together and also add radio hardware. Therefore, corresponding research problems will not be easily solved.

In the USA, the Federal Emergency Management Agency (FEMA) provides support to State and local governments in fulfilment of their responsibilities for preparedness, response, recovery and mitigation of disasters. One method FEMA has used to support State and local emergency communication functions was to sign and implement a Memorandum of Understanding with the American Radio Relay League (ARRL) for amateur radio operators to provide electronic communications for State and local governments in disasters. The Federal Communications Commission (FCC) has licensed more than 600,000 amateur radio operators in the USA. The national organization of amateur radio operators called the American Radio Relay League (ARRL) was formed in 1914. More than 80,000 of these amateurs have registered their availability for emergency communications in disasters in the ARRL's Amateur Radio Emergency Service (ARES). Amateur radio operators have been providing communications in natural disasters such as floods, hurricanes and earthquakes since 1910. Since amateur radio operation was prohibited during the years of both World Wars I and II, FEMA has sponsored a new branch of the amateur service called Radio Amateur Civil Emergency Service (RACES). RACES operators are authorized to operate if the President invokes his War Emergency Powers while all other amateur operation would be silenced. Examines the role of amateur radio in providing emergency electronic communications for disaster management and explores future contributions.

Since the 1980s the performance artist Ricardo Dominguez has been involved in collaborative art projects experimenting with political aesthetics. Critical Art Ensemble, formed in1987, explored intersections between art, technology, political activism as well as criticaltheory. In the 1990s, the Zapatista uprising and its insurgent use of communication technology inspired Dominguez to rethink his notion of art and art's role in society. In 1997Dominguez was co-founder of The Electronic Disturbance Theater. About a decade later,in 2008, the group initiated the installation and performance pieceTransborder ImmigrantTool(TBT). The Electronic Disturbance Theater planned to distribute inexpensive mobilephones among individuals South of the US–Mexico border who planned to cross North.The group had developed a phone app that provided experimental poetry to unauthorizedmigrants while using GPS technology to lead them to water stations in the deserts of theborderlands. As an installation (water stations) and a performance (distribution, poetry,crossing of the border), theTransborder Immigrant Toolcalls attention to the processof crossing the border and the dangers involved. After all, each year about 250 deathsof migrants are registered in the borderlands, most of them caused by dehydration.1TBT's art intervention confronts the public with the borderlands as a place of violenceand death. At the same time, it reflects on art's potential of going beyond its own complicity in power structures. TBT also links art and politics to the technological and digitalizedculture of surveillance. ; Riksbankens Jubileumsfond AB17-1062:1
