Ethnographic methods and geographic information systems were used to investigate the extent, causes and consequences of telephone disconnection in Camden, NJ. The results have significant implications for public policies intended to promote universal telephone penetration. Universal service is usually perceived as an issue for rural areas and the elderly, but the most extensive pockets of low telephone penetration are found in inner cities, where the problem is associated with the young, the transient, and ethnic minorities. The basic monthly rate paid by subscribers is usually thought to be the most important factor affecting affordability, but the data suggest that most marginal users are driven off the network by usage-related costs, and more generally by the problem of credit-worthiness. Given prevailing consumption patterns in low-income urban areas, ''electronic redlining'' seems less of a threat than that poor Americans will, upon exposure to the advanced features of the national information infrastructure (NII), buy services that they cannot afford. Intellectuals and policy analysts value telephone service more than cable television service, but residents of inner cities frequently do not agree with this evaluation. In reformulating universal service policy, we must take account of the growing heterogeneity of telecommunications services, and keep in mind the importance of credit risk as a factor affecting the public's ability to access and use telecommunication networks.  相似文献

During medium to large-scale emergency events such as fires or earthquakes, emergency response teams must be deployed to the location of the event in a timely fashion. Information gathered from 9-1-1 call makers is useful for this, but is not always accurate. In this paper, we show how the space–time permutation scan statistic can be used to detect the presence and location of such events by monitoring the overall spatiotemporal pattern of 9-1-1 emergency calls instead. In an analysis of collected 9-1-1 call data, top detected clusters were found to correlate with emergency events as reported on the news, showing the algorithm's usefulness for automatically estimating their location and temporal extent. We show how the detection procedure works in cases where the emergency event generates a small but statistically significant increase in the number of 9-1-1 calls, as well as cases where events must be detected against a large background activity of 9-1-1 calls. We discuss the possible adoption of the proposed algorithm within the next generation digital government framework.  相似文献

SUMMARY

Telephone reference services have been present in libraries for over seventy-five years. Chat reference services are a very recent addition to library services. Telephone and chat reference share some characteristics and the future of chat reference may be seen through an examination of the history of telephone reference. This article will examine issues of policy, staffing, and technology for telephone and chat reference.  相似文献
