Canadian teachers' attitudes toward change, efficacy, and burnout during the COVID-19 pandemic 

Sokal, Laura; Eblie Trudel, Lesley; Babb, Jeff (Elsevier, 2020-11-19)
Canadian teachers (N = 1626) took part in a longitudinal, national survey conducted at two points early in the COVID-19 pandemic. Results indicated that teacher efficacy, attitudes toward change, and perceptions of ...

The metric dimension and metric independence of a graph 

Currie, James; Oellerman, Ortrud R. (The Charles Babbage Research Centre, 2001)
A vertex x of a graph G resolves two vertices u and v of G if the distance from x to u does not equal the distance from x to v. A set S of vertices of G is a resolving set for G if every two distinct vertices of G are ...

Binary Words Avoiding xxRx and Strongly Unimodal Sequences 

Currie, James D.; Rampersad, Narad (2015-09-14)
In previous work, Currie and Rampersad showed that the growth of the number of binary words avoiding the pattern xxxR was intermediate between polynomial and exponential. We now show that the same result holds for the ...

Counting endomorphisms of crown-like orders 

Currie, James D.; Visentin, Terry I. (Springer, 2002-12)
The authors introduce the notion of crown-like orders and introduce powerful tools for counting the endomorphisms of orders of this type.

The Aveline's Hole 9 Cranium: A Partial Solution to a Long Standing Enigma 

Meiklejohn, Christopher; Schulting, Rick; Musgrave, Jonathan; Babb, Jeff; Higham, Thomas; Richards, David; Mullan, Graham (University of Bristol Spelaeological Society, 2012)
Aveline's Hole is both one of the best-known sites with early human skeletal material in Britain and one of the most problematic in its history. First discovered and explored at the close of the 18th century, it yielded ...

Avoiding approximate repetitions with respect to the longest common subsequence distance 

Camungol, Serina; Rampersad, Narad (Mathematical Sciences Publishers, 2015-09-17)
Ochem, Rampersad, and Shallit gave various examples of infinite words avoiding what they called approximate repetitions. An approximate repetition is a factor of the form x x', where x and x' are close to being identical. ...

Unary patterns under permutations 

Currie, James D.; Nowotka, Dirk; Manea, Florin; Reshadi, Kamellia (Elsevier, 2018-06-04)
Thue characterized completely the avoidability of unary patterns. Adding function variables gives a general setting capturing avoidance of powers, avoidance of patterns with palindromes, avoidance of powers under coding, ...

Teachers' Voices: Pandemic Lessons for the Future of Education 

Eblie Trudel, Lesley G.; Sokal, Laura J.; Babb, Jeff C. (University of Windsor, 2021-05-26)
In late 2019 and early 2020, governments around the world closed educational institutions due to the COVID-19 pandemic. A similar response occurred in Canada and resulted in a sudden pivot by teachers from classroom-based ...

Non-Repetitive Tilings 

Currie, James D.; Simpson, Jamie (The Electronic Journal of Combinatorics, 2002-07-03)
In 1906 Axel Thue showed how to construct an infinite non-repetitive (or square-free) word on an alphabet of size 3. Since then this result has been rediscovered many times and extended in many ways. We present a two-dimensional ...

Skeleton Cave, Leigh Woods, Bristol 

Mullan, G. J.; Meiklejohn, C.; Babb, J. (University of Bristol Spelaeological Society, 2017)
An account is given of the discovery and excavation of this small cave in the 1960s. It is recorded that archaeological finds were made, but of these, only a single human mandible can now be traced. Radiocarbon dating shows ...
