Robust Bounds on the Eigenvalues of Linear Systems With Delays and Their Applications in Stability Analysis

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.

Developing Science Classroom Expectations That Encourage Risk‐Taking for Learning Science Together

open access: yesScience Education, EarlyView.
ABSTRACT Reform‐oriented science classrooms encourage environments in which students engage in a collective enterprise of making sense of their science ideas together. Teachers who strive for these sorts of environments support students in collaboratively constructing and answering their own questions about phenomena and making sense of competing ideas

Family CEO mentoring and post‐CEO succession performance

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary While extant research has studied extensively the consequences of chief executive officer (CEO) succession, we explore the concept of family CEO mentoring (from a departing family CEO to a younger family leader) as a potential driver of post‐succession performance in family firms. Drawing on stewardship theory and using a data
