TVWS policies to enable efficient spectrum sharing

The transition from analogue to the Digital Terrestrial Television (DTV) in Europe is planned to be completed by the end of the year 2012. The DTV spectrum allocation is such that there are a number of TV channels which cannot be used for additional high power broadcast transmitters due to mutual interference and hence are left unused within a given geographical location, i.e. the TV channels are geographically interleaved. The use of geographically interleaved spectrum provides for the so-called TV white spaces (TVWS) an opportunity for deploying new wireless services. The main objective of this paper is to present the spectrum policies that are suitable for TVWS at European level, identified within the COGEU project. The COGEU project aims the efficient exploitation of the geographical interleaved spectrum (TVWS). COGEU is an ICT collaborative project supported by the European Commission within the 7th Framework Programme. Nine partners from seven EU countries representing academia, research institutes and industry are involved in the project. The COGEU project is a composite of technical, business, and regulatory/policy domains, with the objective of taking advantage of the TV digital switchover by developing cognitive radio systems that leverage the favorable propagation characteristics of the UHF broadcast spectrum through the introduction and promotion of real-time secondary spectrum trading and the creation of new spectrum commons regimes. COGEU will also define new methodologies for compliance testing and certification of TVWS equipment to ensure non-interference coexistence with the DVB-T European standard. The innovation brought by COGEU is the combination of cognitive access to TV white spaces with secondary spectrum trading mechanisms.telecommunications,spectrum management,secondary spectrum market,regulation,TV white spaces,cognitive radio

From Behind the Lens: Police Officer Perceptions as Body-Worn Cameras are Introduced Into the New York City Police Department

In 2014, the U.S. District Court ordered the New York City Police Department (NYPD) to test the use of body-worn cameras (BWCs) after finding that their stop, question, and frisk practices violated the rights of some minority New Yorkers. The ruling in Floyd v. City of New York (2013) mandated the recording of future interactions to determine if behavior would be influenced. A total of 54 volunteer officers wore a BWC for a 1-year period and were assigned to six precincts, all selected due to the high frequency of stop, question, and frisk reports prepared by patrol officers. This research examined patrol officer perceptions of the BWC from the lens of the NYPD’s two-officer patrol car. The study revealed unique access to 54 volunteer officers and their non-camera-wearing patrol partners, as they recorded citizen interactions during this pilot period. Further, this study examined the extent officers were open to the adoption of BWCs, providing some of the first-ever evidence for or against claims of increased transparency, accountability and improvements in both officer and citizen behavior during encounters. The respondents’ demographic data were analyzed to determine any relationship with particular viewpoints toward the BWC. The results suggest that patrol officers are in favor of the adoption of a BWC program, and that the BWC had little to no effect on their patrol partnerships. Results also suggest that officers felt comfortable wearing BWCs, and that regardless of their age, gender, years of police experience or years partnering, the existence of the BWC made for better police service in New York City

Minding the Gap: Computing Ethics and the Political Economy of Big Tech

In 1988 Michael Mahoney wrote that “[w]hat is truly revolutionary about the computer will become clear only when computing acquires a proper history, one that ties it to other technologies and thus uncovers the precedents that make its innovations significant” (Mahoney, 1988). Today, over thirty years after this quote was written, we are living right in the middle of the information age and computing technology is constantly transforming modern living in revolutionary ways and in such a high degree that is giving rise to many ethical considerations, dilemmas, and social disruption. To explore the myriad of issues associated with the ethical challenges of computers using the lens of political economy it is important to explore the history and development of computer technology
