Jackson Networks

A network belongs to the monotone separable class if its state variables are homogeneous and monotone functions of the epochs of the arrival process. This framework contains several classical queueing network models, including generalized Jackson networks, max-plus networks, polling systems, multiserver queues, and various classes of stochastic Petri nets. We use comparison relationships between networks of this class with independent and identically distributed driving sequences and the GI/GI/1/1 queue to obtain the tail asymptotics of the stationary maximal dater under light-tailed assumptions for service times. The exponential rate of decay is given as a function of a logarithmic moment generating function. We exemplify an explicit computation of this rate for the case of queues in tandem under various stochastic assumptions.

This mixed-methods research study shows that the incorporation of real-time polling in an introductory Anthropology course (n = 107) taught in a large lecture class at a mid-size university can have a positive impact on students' perceptions of (1) satisfaction; (2) participation; and (3) whether the instructor was able to use the polling results effectively to gauge students' understanding. Independent sample t-test and ANOVA results indicated gender, race, and extroversion level were shown to have significant impacts on participation and understanding. Students did not show a significant preference for either of the two real-time polling systems (TopHat or TurningPoint) used in this study. This study shows how the incorporation of real-time polling in large, introductory, lecture classes can have a positive impact on students and has the potential to decrease the attrition rates and to improve student learning enrolled in these classes.
