title: Habituation and Dishabituation of Physical Activity

authors: Crawford, Demelza

subjects: habituation

abstract: Three experiments with single subject research designs were conducted to see whether habituation occurred as human participants completed physical activity. Experiment 1 had an arrangement where participant’s rates of stationary cycling were recorded throughout 20 minute sessions. Instead of habituation, stationary cycling rates increased over time, likely to be due to a rule that controlled behaviour derived from previous reinforced responding in the same setting as the experimental context. Experiment 2 was arranged similarly to Experiment 1 with an added concurrent task to disrupt the behaviour chain causing the rule-governed behaviour seen in Experiment 1. Despite this concurrent task, rates of stationary cycling again increased due to rule-governed behaviour. Experiment 3 had stationary cycling rates associated with a salient reinforcer that could lose its effectiveness to reinforce over time and thus habituate. Instead, Experiment 3 resulted in stable rates of stationary cycling consistent with task adherence, a rule-governed behaviour. With the failure of habituation to predict the results of this study, they are instead discussed from the more applicable perspective of motivating operations.

title: The average order of the Dirichlet series of the gcd-sum function

authors: Broughan, Kevin A.

subjects: mathematics

abstract: Using a result of Bordellès, we derive the second term and improved error expressions for the partial sums of the Dirichlet series of the gcd-sum function, for all real values of the parameter.

title: Ko wai tēnei e tū ake nei? Activating collectivity and accountability through grounded positioning

authors: Rata, Arama

abstract: Building on conference conversations about positionality—about who we are and how our identities shape our views of the world, about the connections and disconnections experienced between us, and about our proximities to place, power, and privilege—this piece brings together four conference participants to continue to reflect on what positionality means, on why it is important, and on how to practice it in non-performative, well-developed, and mutually nourishing ways. Their dialogue reflects active and critical positioning in process and practice, creating opportunities for acknowledging our relationships and activating both collectivity and accountability in the various spaces where we live, work, create, and hope.
