in the estimates of the input coefficients required to construct a productivity measure. I explicitly incorporate plant exit in the estimation to correct for the selection problem induced by liquidated plants. These methodological aspects are important in obtaining a reliable plant-level productivity measure based

Abstract: Evidence claims depend on fallible assumptions. Three strategies for making true evidence claims in spite of this fallibility are strengthen-ing the support for those assumptions, weakening conclusions, and using multiple independent tests to produce robust evidence. Reliability itself

Research dealing with various aspects of * the theory of planned behavior (Ajzen, 1985, 1987) is reviewed, and some unresolved issues are discussed. In broad terms, the theory is found to be well supported by empirical evidence. Intentions to perform behaviors of different kinds can be predicted

The literature on interference in the Stroop Color-Word Task, covering over 50 years and some 400 studies, is organized and reviewed. In so doing, a set ofl 8 reliable empirical findings is isolated that must be captured by any successful theory of the Stroop effect. Existing theoretical positions

improvement. Investigators and editors developed the original CONSORT (Consolidated Standards of Reporting Trials) statement to help authors improve reporting by using a checklist and flow diagram. The revised CONSORT statement presented in this paper incorporates new evidence and addresses some criticisms

It is far from clear what effect, if any, Australian bicycle helmet legislation has had on reducing the risk of head injury to cyclists involved in crashes. Many early reports of the effectiveness of the legislation are seriously flawed. This is because of the very serious inadequacies of the crash injury databases available, and because of the extreme difficulty of apportioning any changes in injury rates with time to one particular factor when there are very many other factors changing at the same time. The Australian helmet legislation was introduced as part of a Ten-Point road safety package. The Federal government gave states "Black-Spot " road safety money on condition that helmet legislation, and other measures such as 0.05 % blood alcohol limits, were introduced. Compulsory helmet legislation was introduced first in Victoria effective on 1st July 1990. Helmets became compulsory in Western Australia on 1st January 1992. Like many cyclists, I have long promoted helmet wearing and I did not oppose the legislation as I believed that compulsory helmet wearing would be effective. Australian cyclists have had to "wear " the inconvenience of the legislation. Almost nothing of the resultant Black-Spot funds went to bicycle safety. In WA only $69,350 out of $28.3M (0.2%) was

Just as translational medicine follows a long winding path from bench-to-bedside, so can Evidence-Based Medicine be envisioned as comprising a multi-step pipeline, from building evidence from raw data through synthesizing best practices and providing clinical decision support in a process described
