Teacher-to-Parent Communication: What Parents Want from Alternative Educators

This study was conducted to determine teacher-to-parent communication preferences among parents of students, grades 9-12, attending a rural Iowa alternative education program. Thirty-seven parents were chosen to participate in the study. Twenty volunteered to complete the Parent Communication Survey (PCS). Data analysis of the PCS indicated most parents preferred regular progress updates to be sent bi-weekly via U.S. mail. Parents preferred that teachers contact them about more specific issues via phone call home. Over half of parents surveyed said they would read a classroom newsletter and website. An analysis of parent comments yielded four themes: honesty, timeliness, sensitivity, and partnership. Knowledge of these trends will be used to improve communication with parents, develop parental involvement programs, and guide future research

A symbolic algorithm for the synthesis of bounded Petri nets

This paper presents an algorithm for the synthesis of bounded Petri nets from transition systems. A bounded Petri net is always provided in case it exists. Otherwise, the events are split into several transitions to guarantee the synthesis of a Petri net with bisimilar behavior. The algorithm uses symbolic representations of multisets of states to efficiently generate all the minimal regions. The algorithm has been implemented in a tool. Experimental results show a significant net reduction when compared with approaches for the synthesis of safe Petri nets.Peer ReviewedPostprint (author's final draft

A Comparison of Petri Net Semantics under the Collective Token Philosophy

In recent years, several semantics for place/transition Petri nets have been proposed that adopt the collective token philosophy. We investigate distinctions and similarities between three such models, namely configuration structures, concurrent transition systems, and (strictly) symmetric (strict) monoidal categories. We use the notion of adjunction to express each connection. We also present a purely logical description of the collective token interpretation of net behaviours in terms of theories and theory morphisms in partial membership equational logic
