Rhode Island Report on the Judiciary 1973
This is the second annual report produced by the Office of the State Court Administrator. The first report, published in 1973, reviewed the progress made in the administration of the Rhode Island Court System in the period 1969-1972. This report contains the story of continuing progress throughout 1973
Survey of air cargo forecasting techniques
Forecasting techniques currently in use in estimating or predicting the demand for air cargo in various markets are discussed with emphasis on the fundamentals of the different forecasting approaches. References to specific studies are cited when appropriate. The effectiveness of current methods is evaluated and several prospects for future activities or approaches are suggested. Appendices contain summary type analyses of about 50 specific publications on forecasting, and selected bibliographies on air cargo forecasting, air passenger demand forecasting, and general demand and modalsplit modeling
Aircraft requirements for low/medium density markets
A study was conducted to determine the demand for and the economic factors involved in air transportation in a low and medium density market. The subjects investigated are as follows: (1) industry and market structure, (2) aircraft analysis, (3) economic analysis, (4) field surveys, and (5) computer network analysis. Graphs are included to show the economic requirements and the aircraft performance characteristics

Analysis of a discrete-time single-server queue with bursty imputs for traffic control in ATM networks
Due to a large number of bursty traffic sources that an ATM network is expected to support, controlling network traffic becomes essential to provide a desirable level of network performance with its users. Admission control and traffic smoothing are among the most promising control techniques for an ATM network. To evaluate the performance of an ATM network when it is subject to admission control or traffic smoothing, we build a discrete-time single-server queueing model where a new call joins the existing calls.In our model. it is assumed that the cell arrivals from a new call follow a general distribution. It is also assumed that the aggregated arrivals of cells from the existing calls form batch arrivals with a general distribution for the batch size and a geometric distribution for the interarrival times of batches. We consider both finite and infinite buffer cases, and analytically obtain the waiting time distribution and cell loss probability for a new call and for existing calls. Our analysis is an exact one. Through numerical examples, we investigate how the network performance depends on the statistics of a new call (burstiness, time that a call stays in active or inactive state, etc.). We also demonstrate the effectiveness of traffic smoothing to reduce network congestion
'Trust is good, control is better': the 1974 Herstatt-Bank crisis and its implications for international regulatory reform
With its international supervisory and regulatory implications, the failure of Bankhaus Herstatt is one of the landmarks of post-war financial history. This article offers the first comprehensive historical account of the Herstatt crisis, and contributes to the wider discussions on international supervisory and regulatory reform since the mid-1970s, including regulatory capture, markets' self-regulation and resolution of failed banks. In doing so, it first argues that contrary to a widely held view, the German authorities received early and repeated warnings about Herstatt's dealings but this involved only limited and ineffective regulatory/supervisory responses, then it turns to the actual collapse of the bank in June 1974, and finally explores the wider regulatory issues raised by the Herstatt case
Problems and prospects of non-motorized public transport integration in developing cities
The benefits and costs of the paid category of non-motorized public transport (NMPT) –especially three wheeler cycle rickshaws – have long been a major transport planning problem in many developing cities. Policy measures to restrict or eliminate non-motorized vehicles, especially NMPTs, from urban arterials and other feeder networks have already been implemented in developing cities as diverse as Delhi, Bangkok, Jakarta, Manila, Surabaya, Beijing and Bogotá. Over the last few years, the government of Bangladesh has implemented policies to phase out non-motorized transport, particularly rickshaws, from the major traffic spines of Dhaka City. The acceptability, rationality and implication of such ‘solutions’ are widely argued in Bangladesh, as well as internationally. The argument is severe in Dhaka, the case study of this research, considering social acceptability, economic response, fuel free eco-friendly characteristics and magnitude of role of rickshaw in sustaining the traffic and mobility needs of citizens. Therefore, rather than simply pursuing policies to eliminate NMPT, a better approach may be to integrate motorized and non-motorized vehicles as complementary rather than competitive forces in meeting the comprehensive demand of Dhaka’s transport. With the backdrop and given the international significance of the problem, this paper will delineate a preliminary framework for the future place of the NMPT-rickshaw and explore the problems as well as opportunities for its sustainable co-existence in a mixed mode transport stream that best meets the network performance needs of Dhaka
Driver Responses to Graphic-Aided Portable Changeable Message Signs in Highway Work Zones
Portable changeable message signs (PCMSs) have been employed in highway work zones as temporary traffic control devices. Various studies showed that adding graphics to PCMS messages can provide advantages to traditional text messages, such as increasing legibility and improving the understanding of elderly drivers. This article synthesizes the findings of a two-phase research project aimed to investigate driver responses to graphic-aided PCMSs. Different text and graphic-aided PCMSs representing roadwork and flagger were set up in the upstream of highway work zones, and speed data of more than 2,700 vehicles were collected with a series of five speed sensors to determine vehicle speed reduction. Nearly 1,000 onsite driver surveys were performed to identify driver preference on the added graphics. The results discovered that graphic-aided PCMSs reduced mean vehicle speed between 13% and 17% and reduced the speed of passenger cars and trucks significantly differently depending on their locations in work zone. The results indicated that all drivers correctly interpreted the flagger graphic and two work-zone graphics, and suggested that 52% to 71% of drivers preferred to see graphics in PCMS messages. The findings also revealed that driver age did not have a significant impact on driver preference on PCMS message format
