AbstractUniversal service is the focal point of the economic dilemma faced by the telecommunications industry. The advent of competition spurred by several regulatory rulings is forcing rates towards economic costs. It is feared that this movement or the erosion of the toll-to-local subsidy with concomitant increases in local prices severely threatens the concept of universal service. To adequately address these fears, accurate elasticity of demand estimates for telephone access are required. This thesis develops estimates of these demand elasticities for access. These estimates are derived consistently from an underlying theory of demand for access. Furthermore, the simultaneous access and class-of-service choice problems are addressed similarly. This consistent development facilitates model usage and interpretation. For example, the model provides the best available estimate for the size of the network externality. Taking into account the underlying demand theory and acknowledging the problems associated with the aggregated nature of the data set (census tract data from 1980 Census), a modified probit technique is developed to estimate the demand model. The estimation methodology is implemented using an iterative least square procedure. To analyze the reasonableness of the algorithm and procedure, a Monte Carlo study is performed. In addition, a jackknife technique is employed to estimate variances of coefficients when the standard measures are unavailable. The model results are used to analyze the effect of current policy decisions. For example, for a proposed doubling of access prices the demand for access elasticity is found to be quite small, about -.04. A welfare analysis is performed to discuss the costs and benefits associated with moving to cost-based rates. This analysis also provides the basis for rate recommendations to facilitate the transition to competition while attempting to preserve the concept of universal service.

Evaluation of an established telephone triage programVerran, Joyce; Greenberg, Mary Elizabeth (The University of Arizona., 1999)The purpose of this study was to evaluate the outcomes of an established telephone triage (TT) service in a pediatric outpatient clinic. A sample of 25% of all callers triaged at the pediatric clinic in a one month period was randomly selected for participation in the study. A telephone survey was developed and used to guide the data collection. This study demonstrated that the telephone triage program evaluated resulted in the following positive outcomes. First, the TT program was found to be helpful in meeting the needs of the client. Second, clients were satisfied with both the technical and interpersonal aspects of the program. Third, the program resulted in considerable dollar savings for the pediatric clinic. Conclusions were that this TT program lived up to its expected outcomes, and that more research is needed to identify variables and the degree to which they contribute to a successful TT program.
Determinants of demand for residential access and long-distance telephone services in Korea.Lee, Jong Hoon.; Taylor, Lester D.; Zajac, Edward E.; Reynolds, Stanley S.; Fishback, Price (The University of Arizona., 1994)In this dissertation we develop an econometric model of telephone service demand in order to compare the demand characteristics of consumers in Korea and North America and to analyze the effects of policy changes in the telephone service field. To do this, several factors that influence the behavior of call demand are analyzed. We limit ourselves to two different types of call demand: residential access demand and long distance (toll) call demand. For the residential access demand, limited dependent variable techniques are used. Results suggest that the price elasticity for residential access demand in Korea is smaller than those indicated in similar North American studies. The finding is also smaller than that which is found for Korea. The income elasticity of demand for residential access telephone service is found to be much smaller than the estimates obtained by previous researchers in Korea. For toll call demand, pooled cross-sectional/times-series econometric methods were used to estimate the average price and income elasticities of toll call users. The price elasticities for long distance call demand are slightly larger than their counterparts in Canada and the income elasticities are somewhat smaller than those in the US and Canada. It is difficult to compare results with previous Korean studies, since they do not control for the rate level.
Disparities in telephone CPR access and timing during out-of-hospital cardiac arrestNuño, Tomas; Bobrow, Bentley J.; Rogge-Miller, Karen A.; Panczyk, Micah; Mullins, Terry; Tormala, Wayne; Estrada, Antonio; Keim, Samuel M.; Spaite, Daniel W.; Univ Arizona, Coll Med, Arizona Emergency Med Res Ctr; et al. (ELSEVIER IRELAND LTD, 2017-06)Aim: Spanish-only speaking residents in the United States face barriers to receiving potentially life-saving 911 interventions such as Telephone-cardiopulmonary resuscitation (TCPR) instructions. Since 2015, 911 dispatchers have placed an increased emphasis on rapid identification of potential cardiac arrest. The purpose of this study was to describe the utilization and timing of the 911 system during suspected out-of-hospital cardiac arrest (OHCA) by Spanish-speaking callers in Metropolitan Phoenix, Arizona. Methods: The dataset consisted of suspected OHCA from 911 centers from October 10, 2010 through December 31, 2013. Review of audio TCPR process data included whether the need for CPR was recognized by telecommunicators, whether CPR instructions were provided, and the time elements from call receipt to initiation of compressions. Results: A total of 3398 calls were made to 911 for suspected OHCA where CPR was indicated. A total of 39 (1.2%) were determined to have a Spanish language barrier. This averages to 18 calls per year with a Spanish language barrier during the study period, compared with 286 OHCAs expected per year among this population. The average time until telecommunicators recognized CPR need was 87.4 s for the no language barrier group compared to 160.6 s for the Spanish-language barrier group (p < 0.001). Time to CPR instructions started was significantly different between these groups (144.4 s vs 231.3 s, respectively) (p < 0.001), as was time to first compression, (174.4 s vs. 290.9 s, respectively) (p < 0.001). Conclusions: Our study suggests that Hispanic callers under-utilize the 911 system, and when they do call 911, there are significant delays in initiating CPR. (C) 2017 Elsevier B.V.
