Return on Investment (ROI) is one of the most popular performance measurement and evaluation metrics. ROI analysis (when applied correctly) is a powerful tool in comparing solutions and making informed decisions on the acquisitions of information systems. The purpose of this study is to provide a systematic research of the accuracy of the ROI evaluations in the context of information systems implementations. Measurements theory and error analysis, specifically propagation of uncertainties methods, were used to derive analytical expressions for ROI errors. Monte Carlo simulation methodology was used to design and deliver a quantitative experiment to model costs and returns estimating errors and calculate ROI accuracies. Spreadsheet simulation (Microsoft Excel spreadsheets enhanced with Visual Basic for Applications) was used to implement Monte Carlo simulations. The main contribution of the study is that this is the first systematic effort to evaluate ROI accuracy. Analytical expressions have been derived for estimating errors of the ROI evaluations. Results of the Monte Carlo simulation will help practitioners in making informed decisions based on explicitly stated factors influencing the ROI uncertainties.

This article examines the conditions under which organizations publicly respond to unfavorable consumer evaluations that challenge their market identity. Because organizations' market identities are certified by expert evaluations, consumers' devaluations that challenge these expert evaluations represent an identity threat. However, organizations do not always react to consumers' devaluations because of the risks associated to public responses. Hence, we first predict that organizations are more likely to respond to severe devaluations than to weaker ones; second, we propose that organizations, when faced with severe devaluations, are more likely to craft responses that justify their actions and behaviors. We further contend that, for any market identity under consideration, an organization's reputation amplifies these relationships. Analyses of a dataset of London hoteliers' responses to online reviews posted on TripAdvisor during the period 2002-2012 lend substantial support to our hypotheses.

Washington — The Environmental Protection Agency is seeking comment on problem formulation documents for the first 10 chemicals slated for evaluation for potential health and environmental risks under the Frank R. Lautenberg Chemical Safety for the 21st Century Act, as well as a systematic review approach document and a proposed significant new use rule for asbestos.

Washington — The Environmental Protection Agency wants to expand the scope of chemical risk evaluation policies under the Toxic Substances Control Act of 1976.

The number of people evaluated for signs of stroke at U.S. hospitals has dropped by nearly 40% during the COVID-19 pandemic, according to a study led by researchers from Washington University School of Medicine in St. Louis who analyzed stroke evaluations at more than 800 hospitals across 49 states and the District of Columbia.

The U.S. Department of Education continues to quietly approve and negotiate over states' teacher-evaluation systems as part of its No Child Left Behind Act waiver process.

A study from Washington University School of Medicine in St. Louis has found that stroke evaluations fell by nearly 40% during a period of the COVID-19 pandemic, suggesting that many stroke patients are not seeking potentially life-saving medical treatment.
