— In challenging the conventional wisdom at the time, Singer and Prebisch posited a number of explanations for declining terms of trade of developing economies, including both countryand product-specific factors. Over the past decade, we have begun to witness a simultaneous process of price differentiation within commodities (with the prices of some commodities increasing) and within manufactur...

In recent years there has been much interest in alternative sources of income for farmers. This is because economic theory suggests that demand for agricultural commodities is inelastic so that, as incomes in society as a whole increase, those of farmers do not necessarily keep pace Ð hence the current problems with falling real farm incomes. In contrast the demand for services is relatively el...

Computational efficiency and First-In-First-Out (FIFO) are both important issues in applications such as dynamic traffic assignment. In this paper, we first show by example the FIFO properties of a computationally efficient commodity-based kinematic wave (CKW) model of network traffic flow. After developing measurements of FIFO violation among commodities in location and time, based on misplace...

Resource exchange between Grid participants is at the core of Grid computing. Distributed bartering is a distributed and moneyless method of resource exchange. Recent work related to distributed bartering has mainly dealt with resource supplying. However, Grid participants still face an unstable resource environment due to the partial and intermittent nature of the exchanged resources. The prob...

Nursing demands that all care offered to patients is appropriately assessed, delivered and evaluated; the care offered must be up to date and supported by adequately researched published evidence. A basic logic suggests that information and communications technology can help the nurse in maintaining his/her care provision to the highest level through presenting relevant evidence. The nursing ne...

We examine shareholder wealth implications of supplying financing to customers. Robust results suggest that excess returns and changes in trade receivables are directly and significantly related. Further evidence indicates the value of receivables is higher for suppliers with stronger motives relating to operating and contracting costs. The results also suggest a discounted value of receivables...

Auditory saltation is a misperception of the spatial location of repetitive, transient stimuli. It arises when clicks at one location are followed in perfect temporal cadence by identical clicks at a second location. This report describes two psychophysical experiments designed to examine the sensitivity of auditory saltation to different stimulus cues for auditory spatial perception. Experimen...
