Saccade latency delays in young apolipoprotein E (APOE) epsilon 4 carriers
(Elsevier, 2018-11-01)The apolipoprotein E (APOE) epsilon 4 isoform has been associated with a significantly greater risk of developing late onset Alzheimer’s disease (AD). However, the negative effects of APOE-ε4 allele on cognitive function ... -
Sagging resistance of warm formed aluminum brazing sheet
(Elsevier, 2018-04-01)Interrupted tensile tests, performed between room temperature (RT) and 250°C, were used to simulate warm forming of an AA3003/AA4045 brazing sheet. Brazing performance was predicted from sagging distance measurements after ... -
The Saliva Exposome for Monitoring of Individuals’ Health Trajectories
(Environmental Health Perspectives - United States Federal Government, 2017-07-20)Background: There is increasing evidence that environmental, rather than genetic, factors are the major causes of most chronic diseases. By measuring entire classes of chemicals in archived biospecimens, exposome-wide ... -
Sample size and robust marginal methods for cluster-randomized trials with censored event times
(Wiley, 2015-03-15)In cluster-randomized trials, intervention effects are often formulated by specifying marginal models, fitting them under a working independence assumption, and using robust variance estimates to address the association ... -
Scalable image segmentation via decoupled sub-graph compression
(Elsevier, 2018-06-01)Dealing with large images is an on-going challenge in image segmentation, where many of the current methods run into computational and/or memory complexity issues. This work presents a novel decoupled sub-graph compression ... -
Scared of compassion: Fear of compassion in anxiety, mood, and non-clinical groups
(British Psychological Society, 2020-05-04)Objectives. Fear of receiving compassion from others, expressing compassion to others, and being compassionate towards oneself have been identified as potentially important factors in the persistence of depression, stress ... -
School start time changes in the COMPASS study: associations with youth sleep duration, physical activity, and screen time
(Elsevier, 2018-10-12)Background To date, no longitudinal population-based studies of school start times have been conducted within Canada. School schedule changes provided an opportunity to examine start times in association with youth sleep, ... -
Science Communication Sample Slide Deck
(Springer Nature, 2021-01-26)Sample slides to accompany the book chapter: Weaver, K. D., Mercer, K., & Lamont, G. (2021). “The RADAR framework for evaluating sources of information.” In S. Rowland & L. Kuchel (Eds.) Science + SciComm + Work: A guide ... -
A Scoping Review of Frailty and Acute Care in Middle-Aged and Older Individuals with Recommendations for Future Research
(Canadian Geriatrics Society, 2017-03-31)There is general agreement that frailty is a state of heightened vulnerability to stressors arising from impairments in multiple systems leading to declines in homeostatic reserve and resiliency, but unresolved issues ... -
Score tests based on a finite mixture model of Markov processes under intermittent observation
(Wiley, 2019-07-20)A mixture model is described, which accommodates different Markov processes governing disease progression in a finite set of latent classes. We give special attention to the setting in which individuals are examined ... -
Score Tests for Association Under Response-dependent Sampling Designs for Expensive Covariates
(Oxford Journals, 2015-11-27)Response-dependent sampling is widely used in settings where certain variables are expensive to obtain. Estimation has been thoroughly investigated but recent applications have emphasized tests of association for expensive ... -
Scrappy: Using Scrap Material as Infill to Make Fabrication More Sustainable
(ACM Press, 2021-05-06)We present a software system for fused deposition modelling 3D printing that replaces infill material with scrap to reduce material and energy consumption. Example scrap objects include unused 3D prints from prototyping ... -
Searching for a DNAzyme version of the leadzyme
(Springer, 2015-10-12)The leadzyme refers to a small ribozyme that cleaves a RNA substrate in the presence of Pb2+. In an optimized form, the enzyme strand contains only two unpaired nucleotides. Most RNA-cleaving DNAzymes are much longer. Two ... -
Searching for a perceived gaze direction using eye tracking
(Association for Research in Visison and Ophthalmology, 2011-02-01)The purpose of the current study was to use eye tracking to better understand the “stare-in-the-crowd effect”—the notion that direct gaze is more easily detected than averted gaze in a crowd of opposite-gaze distractors. ... -
Secure Comics: An Interactive Comic Series for Improving Cyber Security and Privacy
(Scienceopen, 2017-07)We designed, illustrated, and developed Secure Comics, an online educational interactive comic series about cyber security and privacy. The three-part comic was evaluated with adults and children, and had positive effects ... -
Seeing Double at Memorial University: Two WorldCat Local Usability Studies
(2011-05-01)Presentation slides as presented at the Atlantic Provinces Library Association (APLA) Conference, 2011, St John's Newfoundland. Provides an overview of a usability study conducted on WorldCat Local (WCL), a catalogue for ... -
Seeing Double at Memorial University: Two WorldCat Local Usability Studies
(The Editorial Board of Partnership: The Canadian Journal of Library and Information Practice and Research, 2011)Obtaining user feedback is valuable yet often overlooked, so when Memorial University Libraries launched OCLC’s WorldCat Local discovery tool for Fall 2010, usability testing was a logical next step. Two branches, each ... -
Segregation of chain ends to the surface of a polymer melt: effect of surface profile versus chain discreteness
(Springer, 2016)Silberberg has argued that the surface of a polymer melt behaves like a reflecting boundary on the random-walk statistics of the polymers. Although this is approximately true, independent studies have shown that violations ... -
Selecting the Selection Tool
(2010-06-01)Presentation slides as presented at the CHLA Conference, 2010, Kingston. Authors explain how the book ordering process at Memorial University works, discuss author experiences in evaluating electronic book selection tools, ... -
Selection and Influence: A Meta-Analysis of the Association Between Peer and Personal Offending
(Springer, 2019-06)Objectives Whether people are affected by the criminal behavior of peers (the “influence” perspective) or simply prefer to associate with others who are similar in their offending (the “selection” perspective) is a ...
