disDance 11054.80 Liminalities [video and text]

A special issue based on a selection of papers and performances at 'Remote Encounters: Connecting bodies, collapsing spaces and temporal ubiquity in networked performance, a two-day international conference' (11th - 12th of April 2013) exploring the use of networks as a means to enhance or create a wide variety of performance artsThe disDance project was the beginning of an enquiry-process in which some of the possibilities of working on networked, physically separated, interdisciplinary performance, incorporating interactive media, architecture and dance/performance/audio were investigated. disDance 11054.80 was prepared for the Remote Encounters International Conference and acts as the template for future collaborations using similar methodologies. The piece was sited in two geographically separated locations; Cardiff, UK and Lasalle College of Arts, Singapore. At each site, dancers/performers were interacting with their colleagues at the other site through a novel networked messaging system designed specifically for live performance. Heidi Saarinen, who was the overall creative director, was based in Cardiff (where she was the performer) while Ian Willcock (the developer of the LIMPT system) coordinated from Singapore. The title disDance 11054.80 relates to the collaborative aspect between disparate disciplines and refers to the multi-location aspect as well as holding a factual reference to the distance in kilometers between the two locations involved in the project; Cardiff and Singapore (11054.80 km).Peer reviewedFinal Accepted Versio

National Multi-Modal Travel Forecasts. Literature Review: Aggregate Models

This paper reviews the current state-of-the-art in the production of National Multi-Modal Travel Forecasts. The review concentrates on the UK travel market and the various attempts to produce a set of accurate, coherent and credible forecasts. The paper starts by a brief introduction to the topic area. The second section gives a description of the background to the process and the problems involved in producing forecasts. Much of the material and terminology in the section, which covers modelling methodologies, is from Ortúzar and Willumsen (1994). The paper then goes on to review the forecasting methodology used by the Department of Transport (DoT) to produce the periodic National Road Traffic Forecasts (NRTF), which are the most significant set of travel forecasts in the UK. A brief explanation of the methodology will be given. The next section contains details of how other individuals and organisations have used, commented on or attempted to enhance the DoT methodology and forecasts. It will be noted that the DoT forecasts are only concerned with road traffic forecasts, with other modes (rail, air and sea) only impacting on these forecasts when there is a transfer to or from the road transport sector. So the following sections explore the attempts to produce explicit travel and transportation forecasts for these other modes. The final section gathers together a set of issues which are raised by this review and might be considered by the project

MELDING PRIVATE AND PUBLIC INTERESTS IN WATER RIGHTS MARKETS

The debate over privatizing and water markets has moved back and forth for decades between the "I" and the "We" perspectives. Rather than either/or, a balanced "I&We" view of water institutions is needed. West is meeting east in water law. Public interest needs must be satisfied in appropriate decision forums, but marketing may prove a social improvement when used as a supplement. Balancing an "I&We" institution involves establishing an acceptable or tolerable level of interference through judicious mixing of state, common and private property regimes. Third-party effects are eliminated as mutual gain arises in a variety of decision forums.Property, Interference, Water institutions, Water marketing, Interdependence, Resource /Energy Economics and Policy,

Multiply subtractive generalized Kramers-Kronig relations: application on third harmonic generation susceptibility on polysilane

We present multiply subtractive Kramers-Kronig (MSKK) relations for the moments of arbitrary order harmonic generation susceptibility. Using experimental data on third-harmonic wave from polysilane, we show that singly subtractive Kramers-Kronig (SSKK) relations provide better accuracy of data inversion than the conventional Kramers-Kronig (K-K) relations. The fundamental reason is that SSKK and MSKK relations have strictly faster asymptotic decreasing integrands than the conventional K-K relations. Therefore SSKK and MSKK relations can provide a reliable optical data inversion procedure based on the use of measured data only.Comment: 14 pages, 2 figure

Payment and Settlement Systems in Finland 1995

This paper is an overview of domestic payment and settlement systems in Finland. It contains an up-to-date description of institutional aspects of payment systems, payment media used by non-banks, interbank exchange and settlement circuits and securities settlement systems. At the end of the paper, annual statistics are presented on payment and settlement systems and on payment media for the years 1989–1994.clearing; settlement; payment media; Finland

Forecasting U.S. Macroeconomic and Financial Time Series with Noncausal and Causal AR Models: A Comparison

In this paper, we compare the forecasting performance of univariate noncausal and conventional causal autoregressive models for a comprehensive data set consisting of 170 monthly U.S. macroeconomic and financial time series. The noncausal models consistently outperform the causal models in terms of the mean square and mean absolute forecast errors. For a set of 18 quarterly time series, the improvement in forecast accuracy due to allowing for noncausality is found even greater.Noncausal autoregression; forecast comparison; macroeconomic variables; financial variables
