A Universal Scheme for Transforming Binary Algorithms to Generate Random Bits from Loaded Dice [PDF]

open access: yes, 2012
In this paper, we present a universal scheme for transforming an arbitrary algorithm for biased 2-face coins to generate random bits from the general source of an m-sided die, hence enabling the application of existing algorithms to general sources.

Linear Transformations for Randomness Extraction [PDF]

open access: yes, 2012
Information-efficient approaches for extracting randomness from imperfect sources have been extensively studied, but simpler and faster ones are required in the high-speed applications of random number generation.

Form flows function: Learner‐centered game Re‐design in a STEM classroom

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Biased Probability Judgment: Representative Evidence for Pervasiveness and Economic Outcomes [PDF]

open access: yes
Many economic decisions involve a substantial amount of uncertainty, andtherefore crucially depend on how individuals process probabilistic information. Inthis paper, we investigate the capability for probability judgment in a representativesample of the

A Local Limit Theorem for a Biased Coin Design for Sequential Tests

open access: yesThe Annals of Statistics, 1985
In a clinical comparison of responses to two treatments, patients are admitted sequentially and given one of the two treatments. The allocation is determined randomly, to decrease the possibility of personal bias in the selection of subjects for the test.

Beyond standardisation, subjects and syllabi: How primary schools organise for arts richness in an era of curriculum reform

open access: yesBritish Educational Research Journal, EarlyView.
Abstract As England embarks on its first comprehensive curriculum review in fifteen years, this paper offers critical insights from schools that sustained arts‐rich provision despite a policy landscape hostile to creative subjects. Drawing on data from the Researching Arts‐rich Primary Schools (RAPS) project—a mixed‐methods study of 76 arts‐rich ...

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.
