Radio frequency identification (RFID) adoption: a cross-sectional comparison of voluntary and mandatory contexts
Understanding the adoption factors of a technological innovation is crucial. However, it is a wild assumption that these factors are of similar importance for mandatory and voluntary adoption. Hence, understanding the distinction is critical because, more than often an innovation is adopted with different organizational objectives—though operate in a same industry for a same application. The purpose of this study is to compare the organizational adoption factors of a technological innovation in mandatory and voluntary setting, taking Radio Frequency Identification (RFID) technology as the case innovation. The results indicate that perceptions of the adopters differ significantly on technological, organizational, and environmental characteristics and expectation when the contexts are different. Multi-group analysis confirms that, among the technological factors, compatibility is the major concern in amandatory setting whereas cost and expected-benefits are the main for voluntary adoption; organization’s attitude is more important than organizational resources—in both contexts;and, external pressure is important both in mandatory as well as voluntary environment
Multimessenger search for sources of gravitational waves and high-energy neutrinos: Initial results for LIGO-Virgo and IceCube
We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint operation between 2007-2010. These include parts of the 2005-2007 run and the 2009-2010 run for LIGO-Virgo, and IceCube's observation periods with 22, 59 and 79 strings. We find no significant coincident events, and use the search results to derive upper limits on the rate of joint sources for a range of source emission parameters. For the optimistic assumption of gravitational-wave emission energy of 10-2 M⊙c2 at ˜150 Hz with ˜60 ms duration, and high-energy neutrino emission of 1 051 erg comparable to the isotropic gamma-ray energy of gamma-ray bursts, we limit the source rate below 1.6 ×1 0-2 Mpc-3 yr-1 . We also examine how combining information from gravitational waves and neutrinos will aid discovery in the advanced gravitational-wave detector era.status: publishe
