regional bell Operating Company entry into long distance and non price discrimination against rival interexchange carriers empirical evidence from panel data
2003Co-Authors: Paul R ZimmermanAbstract:The incentive of the Regional Bell Operating Companies (RBOCs) to degrade the quality of interstate access services, an essential input provided to rival long-distance carriers, once they begin offering long-distance services has been a controversial issue in the academic literature. Using a panel of state-level data over the years 1996–2001, this paper investigates whether the RBOCs engage in such ‘non-price discrimination’ upon entering the long-distance market. The results suggest the RBOCs improve the quality of some of their interstate access service offerings before entering the interexchange market, but begin degrading the quality of these services immediately afterward.

regional bell Operating Company entry into long distance and non price discrimination against rival interexchange carriers empirical evidence from panel data
2003Co-Authors: Paul R ZimmermanAbstract:This paper empirically investigates whether Section 271 decisions (i.e., approvals and denials), and the periods surrounding these decisions, affect the quality of interstate access services RBOCs provide to unaffiliated (i.e., rival) IXCs, and thus whether the practice of non-price discrimination by a vertically integrated RBOC is a valid policy concern. A panel of state-level data that contains information on various measures of the quality of interstate access services being provided by the RBOC to rival IXCs, and other measures expected to influence the quality of these services (e.g., state characteristics, degree of network modernization, etc.), is employed to empirically examine the non-price discrimination hypothesis in the context of FCC Section 271 decisions. The empirical results suggest that the RBOCs may indeed degrade the quality of some forms of interstate access services to rival IXCs after obtaining approval to enter the long-distance market. Specifically, the results indicate that the RBOCs tend to increase the quality of their interstate access service offerings in the years prior to the approval of their Section 271 applications, but then begin to degrade the quality of these services almost immediately following their entry into the long-distance market. As such, the measures implemented by state and federal authorities to prevent Section 271-approved RBOCs from acting anti-competitively towards their local exchange competitors should also include more explicit provisions concerning the quality of the interstate access services provided to their unaffiliated long-distance competitors.

Real-time management of telephone Operating Company networks: issues and approaches
1993Co-Authors: S. Kheradpir, W. Stinson, J. Vucetic, A. GershtAbstract:The authors briefly overview the basic characteristics of legacy network management systems used in telephone Operating companies (telcos) and highlight their deficiencies for the emerging network. They further propose a network management methodology for supporting both the embedded base and the new generation of network technologies and services. The proposed approach differs from earlier network management methodologies in three major ways: it is driven by managing service performance and network robustness, rather than managing network equipment; it is based on a global network model that makes "end-to-end" management possible, in contrast to today's highly segmented management; and its decision support and automated applications are "network-state" dependent as opposed to being solely driven by "raw" network measurements.

the performance impact of business process standardization hr case study insights
2010Co-Authors: Bjoern Muenstermann, Alexander Von Stetten, Sven Laumer, Andreas EckhardtAbstract:Purpose – The purpose of this paper is to enhance the understanding of business process standardization and how it contributes to generating business value. This research is a step towards a solid theoretical framework around business process standardization.Design/methodology/approach – A single case study conducted in a global Operating Company is completed. Standardization of a certain business process (in this case the recruiting process) is shown to contribute to business value.Findings – By standardizing its recruiting process, the Company was able to reduce the “time‐to‐hire” from 92 to 69 days and the overall costs of the recruiting process by about 30 percent. The quality of the applicant data has clearly improved. Clarity and transparency of the recruiting process could be increased, while the administrative expense within the human resources (HR) departments in the distinct business locations could be reduced significantly.Research limitations/implications – As with every case study, the genera...

towards an understanding of the business value of business process standardization a case study approach
2008Co-Authors: Alexander Von Stetten, Bjoern Muenstermann, Andreas Eckhardt, Sven LaumerAbstract:What is the business value of process standardization? Alongside the development of industrial engineering of information technology and of business process redesign studied by Davenport and Short (1990), and Davenport’s approach defining business processes (Davenport, 2005), other researchers offer initial insights into business process standardization research opportunities (Venkatesh, 2006). Based on this new thinking about business process standardization, this paper presents a step towards understanding the business value of business process standardization. A single case study with a global Operating Company was conducted to show how a successful standardized business process and a supporting information system can impact the process performance in terms of cost, time and quality. The process studied within the case study is the Company-wide recruiting process. As the results indicate, the Company has improved the overall process performance. The results provide an initial insight into an understanding of the business value of process standardization.

effects of occupational fatigue on cognitive performance of staff from a train Operating Company a field study
2020Co-Authors: Jialin Fan, Andrew Paul SmithAbstract:Background Occupational fatigue is a key issue in the rail industry that can endanger staff, passenger, and train safety. There is a need to demonstrate the relationship between workload, fatigue, and performance among rail staff. Objective The present study, conducted in the workplace in realistic situations, integrating both subjective and objective measurements, aimed at demonstrating the relationship between workload, fatigue, and cognitive performance with a rail staff sample. Methods The "After-Effect" technique was applied in the current study. Online diaries and cognitive performance tasks were used to assess the fatigue, work experiences, and performance of rail staff before and after work on the first and last days of one working week. Results Reported fatigue was greater after work on both the first and last day of the working week. There were large individual differences in the change in fatigue and workload ratings. Analysis of covariance with age and the pre-work performance score as covariates and the post-work performance score as the dependent variable showed that high levels of fatigue were associated with impaired performance on both the visual search and logical reasoning tasks. Workload had fewer effects on performance than fatigue. Conclusion This field study provided evidence for the relationship between work-related fatigue and performance impairment. The findings show the need for future work on predicting fatigue-related performance decrements, and the necessity of providing interventions and support so that the risk to safety can be reduced.
