Age of Onset and Duration of Deafness Drive Brain Organization for Biological Motion Perception in Non-Signers
(2016-09)We used fMRI to characterize the neural responses to biological motion in adults who became deaf at a wide range of ages, none of whom were fluent sign language users. Although hearing people showed stronger activation for ... -
There is a Missing-Phoneme Effect in Aural Prose Comprehension
(SAGE, 2016-05-06)When participants search for a target letter while reading, they make more omissions if the target letter is embedded in frequent function words than in less frequent content words. This phenomenon, called the missing-letter ... -
Reflections on the failure of traditional fisheries management
(2016-06-03)A traditional fisheries management or fish stock assessment takes a Lamarckian-like instructive view of fisheries science. Its invalid inductive arguments have no problem solving capacity and are responsible for the collapse ... -
Thermal, vibrational, and thermoelastic properties of Y2Mo3O12 and their relations to negative thermal expansion
(American Physical Society, 2014-07-21)Y2 Mo3O12, a material that exhibits negative thermal expansion (NTE) from 10 to 1173 K, offers an excellent opportunity to examine relationships between NTE and other physical properties over a wide temperature range. We ... -
The heat capacities of thermomiotic ScF3 and ScF3–YF3 solid solutions
(Springer, 2015-05-01)Scandium trifluoride (ScF3) exists in a cubic ReO3 structure that exhibits negative thermal expansion from 10 to 1100 K, while substituted Sc1−x Y x F3 materials display the same behavior at room temperature but transition ... -
Zero Thermal Expansion in ZrMgMo3O12: NMR Crystallography Reveals Origins of Thermoelastic Properties
(American Chemical Society, 2015-03-23)The coefficient of thermal expansion of ZrMgMo3O12 has been measured and was found to be extremely close to zero over a wide temperature range including room temperature ( = (1.6 ± 0.2) × 10–7 K–1 from 25 to 450 °C by X-ray ... -
Temperature dependent lattice misfit and coherency of Al3X (X = Sc, Zr, Ti and Nb) particles in an Al matrix
(Elsevier, 2015-05-01)The lattice coherency and critical radii for Al3X precipitates in an aluminum matrix were computed using first-principles methods. From density functional perturbation theory and the quasi-harmonic approximation, the unit ... -
Topological constraints and the Makishima–Mackenzie model
(Elsevier, 2015-12-01)Computations of the elastic properties of networks with bond stretch and bond angle bend forces are carried out in order to study their behavior as a function of average coordination number. It is found that the elastic ... -
Relating 139La Quadrupolar Coupling Constants to Polyhedral Distortion in Crystalline Structures
(American Chemical Society, 2015-10-26)A broad series of crystalline lanthanum oxide-based materials has been investigated through high-field 139La solid state nuclear magnetic resonance (ssNMR) spectroscopy and ab initio density functional theory (DFT) ... -
Designing glass with non-dispersive stress-optic response
(Elsevier, 2016-02-01)The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ... -
Nanoindentation Study of the Surface of Ion-Exchanged Lithium Silicate Glass
(American Chemical Society, 2016-02-25)Variations in mechanical properties (stiffness and hardness) were measured as a function of case depth in ion-exchange glasses using nanoindentation. A simple silicate composition, 30Li2O–70Si2O, was exchanged (Li+ ↔ K+) ... -
Mechanical–Structural Investigation of Ion-Exchanged Lithium Silicate Glass using Micro-Raman Spectroscopy
(American Chemical Society, 2016-03-21)Micro-Raman spectroscopy was used to determine the structural modifications occurring in a simple ion-exchanged glass. The base lithium silicate composition 30Li2O–70SiO2 was studied as it underwent ion exchange, Li+ ↔ K+, ... -
A role for generalized Fermat numbers
(American Mathematical Society, 2016)We define a Gauss factorial $N_n!$ to be the product of all positive integers up to $N$ that are relatively prime to $n\in\mathbb N$. In this paper we study particular aspects of the Gauss factorials $\lfloor\frac{n-1} ... -
Demise of the garden of Acadia
(DVL Publishing Inc., Liverpool, Nova Scotia, 1981-07)In the late 1970s, plans were being developed for construction of a tidal power barrage at the mouth of the Annapolis River. Much of the land by the river in that area was dyked and was used by farmers for grazing and ... -
Examining the Feasibility of Implementing a Marine Mammal Oil Spill Response in Canada [graduate project].
(2015-11-23)The coastal waters surrounding Canada are home to diverse ecosystems that provide rich feeding grounds and critical habitat for many marine species. Marine mammals face numerous anthropogenic threats to their recovery and ... -
Coastal Vulnerability for Ship-Source Oil Spill Preparedness and Response Planning in Halifax Harbour, Nova Scotia [graduate project].
(2015-11-23)Ship-source oil spills are amongst the major sources of oil affecting coastal areas. An end-to-end marine oil spill analysis may provide a model to better allocate response resources or prepare contingency plans for highly ... -
A Role for Inuit: How northern communities can inform and influence the dynamics of offshore oil and gas development in Nunavut [graduate project].
(2015-11-23)Climate change and declining ice cover, as well as socio-political and economic incentives, are increasingly attracting corporate attention towards the Canadian North. Oil and gas companies have renewed their interests in ... -
Shipping and Seismic Exploration Noise in the Arctic Marine Soundscape: A look at Mitigation Measures for Cetaceans [graduate project].
(2015-11-23)Increasing levels of anthropogenic noise in the Arctic marine soundscape can have negative effects on cetaceans that have adapted to a relatively pristine acoustic environment and are unaccustomed to the loud, low frequency ... -
Bycatch 22: Regulatory pressures of selective fishing on commercial salmon fishers and impacts of handling on chum salmon (Onchorhynchus keta) released from purse seine fisheries in Northern British Columbia. [graduate project].
(2015-11-23)In Canadian Pacific salmon fisheries, a policy of selective fishing practices was introduced to reduce impacts on salmon populations of conservation concern while allowing fisheries to continue on species that can withstand ... -
Applying Adaptive Management Approaches to Data Limited Fisheries: The Case of Bermuda’s Shallow Water Snapper Species [graduate project].
(2015-11-23)The sustainable management of ecosystems, marine resources, and resource users is essential to ensure ecosystem health and resilience. A vast majority of global fish stocks lack adequate data to determine fish stock health ...
