We report illusions we observed while investigating thresholds for detecting a deviation in one out of several trajectories of dots moving in straight lines (Tripathy and Barrett 2003). The deviating trajectory consisted of two straight-line segments, with the deviation occurring in the middle of the trajectory, at the intersection of the two segments. Robust distortions were noticed in the sha...

Recent research works have shown control statistics based on squared deviation of observations from target have the ability to monitor variability in both univariate and multivariate processes. In the current research, the properties of the control statistic t S that has been proposed by Huwang et al. (Journal of Quality Technology 2007; 39: 258-278) are first reviewed and three new t S -based ...

Digital inequality, or the unequal access and use of information communication technologies, inhibits under-privileged people from opportunities in the digital world. Although government and private organizations have devoted considerable resources to address this inequality, issues remain unsolved. A theory-based investigation of the phenomenon is essential for effective policy-making and inte...

The traditional estimation of mixture regression models is based on the normal assumption of component errors and thus is sensitive to outliers or heavy-tailed errors. A robust mixture regression model based on the t−distribution by extending the mixture of t−distributions to the regression setting is proposed. However, this proposed new mixture regression model is still not robust to high leve...

and an anonymous referee for helpful comments and suggestions. Abstract This paper investigates how firms determine the capital structure of a subsidiary that is divested in a spin-off. In a spin-off, the parent divides the assets of the firm and chooses the capital structure for the new, stand-alone entity. Unlike the firms in other capital structure studies, the subsidiary's leverage ratio is...

_____________________________________________________________________________ Abstract: Significant increases in the level of target leverage have been previously documented, following unsuccessful takeover attempts. Increased leverage may signal managerial commitment to improved performance, suggesting that corporate performance and leverage should be positively related. If, however, the incre...
