Recent models of monetary policy have analyzed the desirability of different optimal and ad hoc interest rules under the restrictive assumption that forecasts of the private sector and the central bank are homogenous. This paper studies the implications of heterogeneity in forecasting by the central bank and private agents for the performance of interest rules in a framework of econometric lear...

This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed olid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency nd power density are observed for isothermal and adiabatic operational regimes. The influence of air numbe...

Data re-sampling methods such as the delete-one jackknife are a common tool for estimating the covariance of large scale structure probes. In this paper we investigate the concepts of internal covariance estimation in the context of cosmic shear two-point statistics. We demonstrate how to use log-normal simulations of the convergence field and the corresponding shear field to carry out realisti...

A total of 6444 ratings of the financial performance of 424 third- and fourth-year medical students were made by house officers and attending teachers during 12 separate internal medicine rotations. Ratings were based on 13 behaviourally anchored rating scales. One rating was randomly selected per student per evaluator type (house officer and attending teacher) during each of the 12 rotation pe...

Since the introduction of the Sarbanes-Oxley (SOX) Act in 2002, companies have begun to place more emphasis on information technology (IT) internal controls. IT internal controls are policies that provide assurance that technical systems operate as intended, provide reliable data, and comply with regulations. Research suggests that firms with strong internal controls perform better than those w...

Our work is being conducted with the aim to develop an effervescent atomizer for industrial burners that will generate a fine and stable spray in large turn-down ratio. The single-hole, plain orifice atomizer is powered with light heating oil and uses air as an atomizing medium in the “outside-in” gas injection configuration. Published design concepts of the effervescent atomizer are described....

OBJECTIVE To determine what factors have a significant influence on the performance of medical device maintenance outsourcing, and to determine how the performance of external governance structures differs depending on whether a hospital is private or public. METHODS This was a longitudinal study of 590 maintenance transactions at 20 hospitals in Bogotá, Colombia, involving 764 medical device...
