Channel Occupancy-Based Dynamic Spectrum Leasing in Multichannel CRNs: Strategies and Performance Evaluation
2016
Spectrum leasing has been proposed as an effective approach for enabling more flexible spectrum utilization in CRNs. In CRNs, a primary network (PN) which consists of multiple primary users (PUs) can lease part of the licensed spectrum to secondary users (SUs) in exchange for operational benefits. The focus of this study is to investigate how and to what extent the PN allows spectrum leasing in CRNs, considering the QoS requirements of the PN and the secondary network (SN). Correspondingly, we propose two dynamic spectrum leasing strategies, which can improve the QoS performance of SUs while ensuring sufficient remuneration for PUs. In order to dynamically adjust the portion of leased bandw…
Educational strategies on potential prescribers to implement correct use of genomic tests: the Italian experience.
2012
Abstract background Marketing pressures, regulatory policies, clinical guidelines, and consumer’s demand all affect health care providers' knowledge and use of health-related genetic tests sold and/or advertised to consumers. A survey on health care providers’ and consumers’ awareness, perceptions, and use of direct-to-consumer personal genomic tests, conducted in USA in 2008, suggested a strong need for education of health practitioners. A similar survey, administered among Italian general practitioners (GPs), has documented that the 85% of interviewers reported the need for specific training on predictive tests’ prescription. Based on these premises, the Italian Health Ministry has introd…
