Can financial ratios detect fraudulent financial reporting

Abstract: Fraudulent financial reporting is a matter of grave social and economic concern. The Treadway Commission recommended that the Auditing Standards Board require the use of analytical procedures to improve the detection of fraudulent financial reporting. This is an exploratory study to determine if financial ratios of fraudulent companies differ from those of nonfraudulent companies. Fraudulent firms were identified by examining the SEC's Accounting and Auditing Enforcement Releases issued between 1982 and 1999. The fraudulent firms (n=79) were then matched with nonfraudulent firms on the basis of firm size, time period, and industry. Using this matched‐pairs design, ratio analysis for a seven‐year period (i.e. the fraud year −/+ 3 years) was conducted on 21 ratios. Overall, 16 ratios were found to be significant. Of these, only three ratios were significant for three time periods. Of the 16 statistically significant ratios, only five were significant during the period prior to the fraud year. Using discriminant analysis, misclassifications for fraud firms ranged from 58 percent to 98 percent. These results provide empirical evidence of the limited ability of financial ratios to detect and/or predict fraudulent financial reporting.

A conversational robot in an elderly care center: an ethnographic study

Abstract: This paper reports an ethnographic study on the use of a conversational robot. We placed a robot for 3.5 months in an elderly care center. Assuming a real deployment scenario, the robot was managed by a single non-programmer person during the field trial, who teleoperated the robot and updated the contents. The robot was designed to engage in daily greetings and chatting with elderly people. Through the ethnographic approach, we clarified how the elderly people interacted with this conversational robot, how the deployment process adopted to introduce the robot was designed, and how the organization's personnel involved themselves in this deployment.
