retransmit events. Our measurements demonstrate that our model is able to more accurately predict TCP throughput and is accurate over a wider range of loss rates. This material is based upon work supported by the National Science Foundation under grants NCR-95-08274, NCR-95-23807 and CDA-95-02639. Any

to work well. In this paper we investigate loopy prop agation empirically under a wider range of conditions. Is there something special about the error-correcting code setting, or does loopy propagation work as an approximation scheme for a wider range of networks? ..\ x(:x).) (1) where: and: The message

Machine learning for text classification is the cornerstone of document categorization, news filtering, document routing, and personalization. In text domains, effective feature selection is essential to make the learning task efficient and more accurate. This paper presents an empirical comparison

A growing body of empirical work has documented the superior performance characteristics of exporting plants and firms relative to non-exporters. Employment, shipments, wages, productivity and capital intensity are all higher at exporters at any given moment. This paper asks whether good firms

Abstract In both corporate finance and asset pricing empirical work, researchers are often confronted with panel data. In these data sets, the residuals may be correlated across firms and across time, and OLS standard errors can be biased. Historically, the two literatures have used different

This paper presents a critical appraisal of resilience, a construct connoting the maintenance of positive adaptation by individuals despite experiences of significant adversity. As empirical research on resilience has burgeoned in recent years, criticisms have been levied at work in this area

Although the relationship metaphor dominates contemporary marketing thought and practice, surprisingly little empirical work has been conducted on relational phenomena in the consumer products domain, particularly at the level of the brand. In this article, the author: (1) argues for the validity

to the highest value use without substantial risk of loss through moral hazard, adverse selection, or transactions costs { are an essential catalyst of economic growth. Empirical work seems consistent with this argument. For example, on the

This well-written book assembles much of the empirical work written on job creation and destruction. It is well laid out and accessible to both specialists

of research, and inspired several successful change projects involving the redesign of work (e.g., For one, a number of researchers have been unable to provide empirical support for the major tenets of the two-factor theory itself (see, for example, Moreover, the theory does not provide for differences
