Public safety agencies at various levels of government have joined together to share information and communicate when faced with public safety incidents. Interagency collaboration initiatives of this nature result in the creation of public safety networks. Public safety networks may originate at any level of government, and their user base may span a single or multiple geographies.〔Williams, C., Fedorowicz, J. and Tomasino, A. ''Government Factors Associated with State-wide Interagency Collaboration Initiatives''. Paper presented at the 11th Annual Conference on Digital Government (Puebla, Mexico, 2010) http://dl.acm.org/citation.cfm?id=1809881&dl=ACM&coll=DL&CFID=61521807&CFTOKEN=96344159〕 This description focuses on public safety networks in the United States. Public safety networks are receiving more attention and priority in the United States as the country deals with ever increasing threats from terrorism and natural disasters. Such a network of public safety agencies, supported by an information and communications technology infrastructure emerges from the individual and collaborative behaviors of their member agencies.〔Tomasino, Arthur, ''Public Safety Networks as a Type of Complex Adaptive System.'' Proceedings in the 2011 International Conference on Complex Systems, Boston, MA, June 26- July 1, 2011. http://necsi.edu/events/iccs2011/papers/77.pdf〕 Public safety networks are defined differently as seen from different perspectives. From an organizational systems perspective a public safety network is an information technology (IT) enabled collaborative, inter-organizational system. From a communications network perspective it is a wireless network used by emergency services. Both definitions are the accepted within the public safety sector. == Organizational perspective == Public safety organizations are limited in their ability to communicate and share information with other agencies even though they have the technology in place to do so within their own boundaries. Public safety networks help agencies realize the value of joining together to design, develop and deploy information and communications technologies to support policing, criminal justice, public safety and homeland security. From the organizational perspective a public safety network is an interagency collaboration focused on the development and use of information and communication technologies (ICT) to support the information sharing and functional interoperability needs of public safety organizations engaged in law enforcement, criminal justice, and emergency response. As such a public safety network is a specific form of the broad class of inter-organizational information sharing systems (IOS) supporting information sharing among police and other public safety agencies.〔Fedorowicz, Jane, Steve Sawyer, Christine Williams, M. Lynne Markus, Michael Tyworth, Dax Jacobson, Sonia Gantman, Martin Dias, and Arthur Tomasino, ''Design Observations Regarding Public Safety Networks''. 12th International Digital Government Research Conference (dg.o), Washington, D.C., June 12–15, 2011. http://dl.acm.org/citation.cfm?id=2037556.2037601〕 As an IOS a public safety network has an inherent complexity due to the wide range of factors that compromise the network. The formation, structure and operation of public safety network can be affected by any number of factors including rational choices made by public safety officials, political priorities, institutional considerations and capabilities of enabling ICT. The number of potential factors lending themselves to the explanation and understanding of public safety network is considerable.〔Williams, Christine B., Jane Fedorowicz, Steve Sawyer, Martin Dias, Dax Jacobson, Michael Tyworth and Sonia Vilvovsky, ''The Formation of Inter-Organizational Information Sharing Networks in Public Safety: Cartographic Insights on Rational Choice and Institutional Explanations'', Information Polity, Vol. 14, Nos. 1-2, 2009, pp. 13-29. http://iospress.metapress.com/content/078h05v067n74732/〕 Organizational perspective on public safety networks have used frameworks from rational choice, institutional, and complexity theory to understand their formation and operations.〔The Public Safety Networks Study, http://www.publicsafetynetworksstudy.org/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「public safety network」の詳細全文を読む スポンサード リンク
