The organizational impact of docket 19880

The field of emergency medical services (EMS)provides an organizational and operational environment which lacks the geopolitical structure and discipline of other public safety services. The opportunity to rearrange the various service provider elements of EMS into a unified regional agency is not likely in current political and economic circumstances. The new EMS radio communications structure which has evolved from Federal Communications Commission Docket 19880 provides the opportunity for operational order and discipline within the various provider elements of EMS. Despite the opportunity for creating the common system approach to EMS communications, many human elements must be dealt with in breaking down traditional barriers to change.

From MEDICOM to MED-8: The growing pains in EMS radio

MEDICOM, an emergency medical services (EMS) communications system conceived in 1968 and which became a reality in 1973, is described. This system was implemented before the development of FCC Docket 19880 and uses EMS radio communications channels not specified in that docket. Insights are provided on problems that face government agencies such as FCC, DOT, DHEW, and NTIA in relation to regulation and funding of EMS communications.     

Emergency management systems using mobile cloud computing: A survey

Among today's rapidly evolving technologies, artificial intelligence plays a significant role in making decisions by a system without any human intervention. An Emergency Management System (EMS) is a decision support system where emergencies such as tsunami, landslide, fire, cyclone, and electrical short circuits can be prevented with prior detection and can be addressed immediately in an efficient way after the emergency occurred. Automation of EMS can avoid or manage multiple emergencies, which alternatively can save lives, economy, and environment. Quality demand response with fast data transfer, error minimized computation, and effective resource utilization is very much essential while developing the EMSs. This will provide a bridge between the technology and emergency responders. Resource-limited smart devices can be made rich in computational behavior by outsourcing their requirements such as storage, virtual servers, and web services using Mobile Cloud Computing (MCC). In this work, we have done a detailed survey on both MCC applications and EMS applications proposed in the literature, and we have also identified the design challenges handled in both MCC and EMS applications. We have presented the design challenges and possible solutions for development of EMS using MCC. We propose an architecture for building an automated EMS using MCC. Finally, we conclude the paper with specific future directions.

Assessing the Core Resources in the Environmental Management System From the Resource Perspective and the Contingency Perspective

The purpose of this paper is twofold. The first objective is to examine the core resources that make environmental management system (EMS) a potential basis of sustainable competitive advantage from the resource-based view of the firm. The second objective is to investigate the set of core resources from the contingency perspective. Particularly, experience in implementing other manufacturing systems and the stage of EMS implementation were tested as the contingency factors. The proposed model and its related hypotheses were tested using structural equation modeling on a large-scale database consisting of 1453 respondents. The results showed that it is the tacit resources within an EMS, in the form of top management team's strategic perception, cross-functional cooperation, and environmentally responsible suppliers, which help explain firmspsila operational performance. The findings provided the general principles in investment decisions of EMS. However, the results also demonstrated that the pattern of the core resources varies across firms with different experience in other manufacturing systems and at different stages of EMS implementation. As a result, there is no standard bundle of critical resources for each firm. Rather, firms need to tailor their resource investment decisions in light of these factors beyond the general principles.
