Improving Networking Supports For Women In The Workplace, Karen E. Pennesi, Javier Alvarez Vandeputte, Zsofia Agoston, Rawand Amsdr

Anthropology Publications

This report describes findings from research on networking activities and strategies among women in executive and leadership positions in Canadian organizations. The project was carried out by graduate student researchers in collaboration with the Women's Executive Network. Networking is defined as the creation and maintenance of a community of diverse interests, through in-person and online engagements, that can be mobilized for the benefit of oneself or other members of one’s network. We found that the shift to primarily online networking activities due to COVID-19 removed some existing barriers related to age, gender and location, while introducing others related to family …

Identity Salience Moderates The Effect Of Social Dominance Orientation On Covid-19 ‘Rule Bending’, Rhiannon Macdonnell, Bonnie Simpson, Jennifer Chernishenko, Shreya Jain

Management and Organizational Studies Publications

Amidst the economic, political, and social turmoil caused by the COVID-19 pandemic, contrasting responses to government mandated and recommended mitigation strategies have posed many challenges for governments as they seek to persuade individuals to adhere to prevention guidelines. Much research has subsequently examined the tendency of individuals to either follow (or not) such guidelines, and yet a ‘grey area’ also exists wherein many rules are subject to individual interpretation. In a large study of Canadians (N =1032, Mage =34.39, 52% female; collected April 6, 2020), we examine how social dominance orientation (SDO) as an individual difference predicts individual propensity to …

Machine Learning For Stock Prediction Based On Fundamental Analysis, Yuxuan Huang, Luiz Fernando Capretz, Danny Ho

Electrical and Computer Engineering Publications

Application of machine learning for stock prediction is attracting a lot of attention in recent years. A large amount of research has been conducted in this area and multiple existing results have shown that machine learning methods could be successfully used toward stock predicting using stocks’ historical data. Most of these existing approaches have focused on short term prediction using stocks’ historical price and technical indicators. In this paper, we prepared 22 years’ worth of stock quarterly financial data and investigated three machine learning algorithms: Feed-forward Neural Network (FNN), Random Forest (RF) and Adaptive Neural Fuzzy Inference System (ANFIS) for …

© 2021, The Author(s). Nutritional intake can promote early neonatal brain development in very preterm born neonates (< 32 weeks’ gestation). In a group of 7-year-old very preterm born children followed since birth, we examined whether early nutrient intake in the first weeks of life would be associated with long-term brain function and neurocognitive skills at school age. Children underwent resting-state functional MRI (fMRI), intelligence testing (Wechsler Intelligence Scale for Children, 5th Ed) and visual-motor processing (Beery-Buktenica, 5th Ed) at 7 years. Relationships were assessed between neonatal macronutrient intakes, functional connectivity strength between thalamic and default mode networks (DMN), and neuro-cognitive function using multivariable regression. Greater functional connectivity strength between thalamic networks and DMN was associated with greater intake of protein in the first week (β = 0.17; 95% CI 0.11, 0.23, p < 0.001) but lower intakes of fat (β = − 0.06; 95% CI − 0.09, − 0.02, p = 0.001) and carbohydrates (β = − 0.03; 95% CI − 0.04, − 0.01, p = 0.003). Connectivity strength was also associated with protein intake during the first month (β = 0.22; 95% CI 0.06, 0.37, p = 0.006). Importantly, greater thalamic-DMN connectivity strength was associated with higher processing speed indices (β = 26.9; 95% CI 4.21, 49.49, p = 0.02) and visual processing scores (β = 9.03; 95% CI 2.27, 15.79, p = 0.009). Optimizing early protein intake may contribute to promoting long-term brain health in preterm-born children.

Musical Instrument Familiarity Affects Statistical Learning Of Tone Sequences., Stephen C Van Hedger, Ingrid Johnsrude, Laura J Batterink

Brain and Mind Institute Researchers' Publications

Most listeners have an implicit understanding of the rules that govern how music unfolds over time. This knowledge is acquired in part through statistical learning, a robust learning mechanism that allows individuals to extract regularities from the environment. However, it is presently unclear how this prior musical knowledge might facilitate or interfere with the learning of novel tone sequences that do not conform to familiar musical rules. In the present experiment, participants listened to novel, statistically structured tone sequences composed of pitch intervals not typically found in Western music. Between participants, the tone sequences either had the timbre of artificial, …

Family Functioning As A Moderator In The Relation Between Perceived Stress And Psychotic-Like Experiences Among Adolescents During Covid-19, Zhipeng Wu, Zhulin Zou, Feiwen Wang, Zhibiao Xiang, Mengran Zhu, Yicheng Long, Haojuan Tao, Lena Palaniyappan, Zhening Liu

Brain and Mind Institute Researchers' Publications

Background: The COVID-19 pandemic has increased psychological stress among adolescents, and the relation between perceived stress (PS) and psychotic-like experiences (PLEs) has been well-established. However, little is known about the role of family functioning (FF) in this relation, especially when adolescents experienced the extended lockdown period with family members. Methods: A total of 4807 adolescents completed this retrospective paper-and-pencil survey after school reopening between May 14th and June 6th, 2020 in Hunan Province, China. We measured PS with the Perceived stress scale (PSS-10), PLEs with the eight positive items from Community Assessment of Psychic Experiences (CAPE-8), and FF with the …

Racial Limitations On The Gender, Risk, Religion & Politics Model, Amanda Friesen

Political Science Publications

Risk aversion dampens political participation and heightens religiosity, with concentrated effects among women. Yet, little is known about how intersecting identities moderate these psychological correlates of religiosity and political engagement. In this paper, we theorize that the risk-religion-politics relationship is gendered and racialized. Using a nationally representative survey, we show that political participation is more strongly correlated with risk for Black women than for any other race-gender group. For religiosity, however, we find little evidence that risk is related to religiosity among Black women, while highly correlated with white women's religious engagement. For men—whether Black or white—risk exhibits a modest, …

Predicting Pro-Environmental Values And Behaviors With The Supernumerary Personality Inventory And Hope, Bonnie Simpson, Meghan Maguire, Julie Aitken Schermer

Management and Organizational Studies Publications

This research examinesthe role ofpersonality traits beyond the Five-Factor Model (FFM) frameworkin predicting pro-environmental values and behaviors. A sample of 410participants completed personality scalesand reported both their environmental values and the extent to which they had engaged in a series of pro-environmental behaviors in the preceding 24 hours. Small positive correlations were found between environmental values and behaviors with integrityand femininityand negative correlations with religiosity. Overall, the results show limited evidence supporting the personality dimensions measured in predicting pro-environmentalvalues and behaviors.Implications of the findings are discussed.

SASAH 4th Year Capstone and Other Projects: Publications

When my exchange was shortened due to COVID-19, I had the opportunity to undertake a part-time research assistant position with Dr. Jeff Tennant in the French and Linguistics departments at Western. Our project studied the rhythm and intonation of the speech of Franco-Ontarians. This paper serves as a description and reflection of this experiential learning opportunity. Specifically, it explores the challenges of operating within a multi-year project timeline as well as dealing with imposter syndrome as a student new to true research.

This project examined the spoken language of bilingual Ontarians to determine if the classically distinct rhythm patterns of …

Regional Brain And Spinal Cord Volume Loss In Spinocerebellar Ataxia Type 3, Jennifer Faber, Tamara Schaprian, Koyak Berkan, Kathrin Reetz, Marcondes Cavalcante França, Thiago Junqueira Ribeiro De Rezende, Jiang Hong, Weihua Liao, Bart Van De Warrenburg, Judith Van Gaalen, Alexandra Durr, Fanny Mochel, Paola Giunti, Hector Garcia-Moreno, Ludger Schoels, Holger Hengel, Matthis Synofzik, Benjamin Bender, Gulin Oz, James Joers, Jereon J. De Vries, Jun Suk Kang, Dagmar Timmann-Braun, Heike Jacobi, Jon Infante, Richard Joules, Sandro Romanzetti, Jorn Diedrichsen, Matthias Schmid, Robin Wolz, Thomas Klockgether

Brain and Mind Institute Researchers' Publications

Background: Given that new therapeutic options for spinocerebellar ataxias are on the horizon, there is a need for markers that reflect disease-related alterations, in particular, in the preataxic stage, in which clinical scales are lacking sensitivity. Objective: The objective of this study was to quantify regional brain volumes and upper cervical spinal cord areas in spinocerebellar ataxia type 3 in vivo across the entire time course of the disease. Methods: We applied a brain segmentation approach that included a lobular subsegmentation of the cerebellum to magnetic resonance images of 210 ataxic and 48 preataxic spinocerebellar ataxia type 3 mutation carriers …

Reading Times: Exploring The Temporalities Of Reading, Paulette Rothbauer, Lucia Cederia Serantes

FIMS Publications

Purpose

The purpose of this paper is to explore various concepts of time and temporal dimensions in the context of everyday reading experiences.

Design/methodology/approach

The study uses theoretical bricolage that puts existing reading research into conversation with theories of time and temporalities.

Findings

Three registers of time in reading are put forward: (1) libraries and books as places that readers return to again and again over time, (2) temporalized reading bodies and (3) everyday reading as a temporalized practice.

Research limitations/implications

Using lenses of time and temporalities, everyday reading is shown to be central to ways of being in time. …

Functional Organization Of Frontoparietal Cortex In The Marmoset Investigated With Awake Resting-State Fmri, Yuki Hori, Justine C. Cléry, David J. Schaeffer, Ravi S. Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

Frontoparietal networks contribute to complex cognitive functions in humans and macaques, such as working memory, attention, task-switching, response suppression, grasping, reaching, and eye movement control. However, there has been no comprehensive examination of the functional organization of frontoparietal networks using functional magnetic resonance imaging in the New World common marmoset monkey (Callithrix jacchus), which is now widely recognized as a powerful nonhuman primate experimental animal. In this study, we employed hierarchical clustering of interareal blood oxygen level-dependent signals to investigate the hypothesis that the organization of the frontoparietal cortex in the marmoset follows the organizational principles of the macaque frontoparietal …

Sustained Neural Activity Correlates With Rapid Perceptual Learning Of Auditory Patterns, Björn Herrmann, Kurdo Araz, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

Repeating structures forming regular patterns are common in sounds. Learning such patterns may enable accurate perceptual organization. In five experiments, we investigated the behavioral and neural signatures of rapid perceptual learning of regular sound patterns. We show that recurring (compared to novel) patterns are detected more quickly and increase sensitivity to pattern deviations and to the temporal order of pattern onset relative to a visual stimulus. Sustained neural activity reflected perceptual learning in two ways. Firstly, sustained activity increased earlier for recurring than novel patterns when participants attended to sounds, but not when they ignored them; this earlier increase mirrored …

How Long Do Mood Induction Procedure (Mip) Primes Really Last? Implications For Cognitive Vulnerability Research., Jennifer C P Gillies, David J A Dozois

Psychology Publications

BACKGROUND: Mood Induction Procedures (MIPs) are used widely in research on cognitive vulnerability to depression. Although empirical evidence supports certain MIPs as effective, little research has evaluated whether MIP-induced sad moods are sufficiently persistent. This study aimed to determine (1) how long an MIP-induced mood lasts according to commonly used operational definitions and (2) whether these findings vary according to the type of MIP used.

METHODS: Four-hundred-and-one undergraduate students were randomly assigned to one of three commonly used sad MIPs (music, memory, music+memory) or to one of three matched neutral MIPs. Mood was repeatedly measured immediately prior to and following …

Decolonizing & Indigenizing Lis, Heather Hill, Marni Harrington, Paulette Rothbauer, Danica Pawlick Potts

FIMS Publications

What does it mean to Indigenize and decolonize a Master of Library and Information Science (MLIS) program? This paper outlines the process by which one Canadian MLIS program responded to the reports from the Truth and Reconciliation Commission of Canada and the Canadian Federation of Library Association Indigenous Matters Committee that specify the implications and provide guidelines for best practices for librarianship and the information professions across Canada. In outlining the challenges of re-engineering our standard procedures, practices, and pedagogies, this paper provides a path forward for other MLIS programs looking to critically evaluate and develop their own programs.

How Affective Displaysand Self-Construal Impact Consumers’ Generosity, Rhiannon Macdonnell, Bonnie Simpson

Management and Organizational Studies Publications

Nonprofit brands vary widely in their positioning to consumers, ranging from crisis and desperation, to joy and optimism.The literature, however, provides limiteddirection for the many nonprofit organizations that seek to align their brand with positive emotions. Herein, we examine the relationship between affective displays (sad vs. happy) portrayed in charitable advertisements and consumer self-construal in shaping consumer generosity.We employ one field study (study 1) and one lab experiment (study 2), using different charitable causes (i.e., Kiva.org[study 1] and a fictitious children’s cancer charity [study 2]) and currencies (i.e., lending money [study 1] and volunteering time [study 2]).Taken together, we find …

Political Taste: Exploring How Perception Of Bitter Substances May Reveal Risk Tolerance And Political Preferences, Amanda Friesen

Political Science Publications

Risk is endemic to the political arena and influences citizen engagement. We explore this connection by suggesting that risk-taking may be biologically instantiated in sensory systems. With specific attention to gender and gender identity, we investigate the connections between self-reported bitter taste reception, risk tolerance, and both of their associations with political participation. In three U.S. samples collected in 2019 and 2020, participants were asked to rate their preferences from lists of foods as well as whether they detected the taste of the substance N-Propylthiouracil (PROP) and, if so, the strength of the taste. In this registered report, we find …

The Mobility Of Experiential Learning Pedagogy: Transferring Ideas And Practices From A Large- To A Small-Campus Setting, Roza Tchoukaleyska, Ken Carter, Emily Dluginski, Marilyn Forward, Andrew King, Olivia Leblanc, Christopher Ratcliffe

Geography & Environment Publications

In this article, we examine the development of a new, experiential learning human geography and planning course at a smaller campus in Newfoundland, Canada. Our interest is twofold: to consider how pedagogical approaches can be transferred between a large urban campus and a small-town location; and to examine the benefits and complications of such transfers through a reflective examination of the resulting experiential learning program. The article captures the experiences of students, faculty, and university engagement staff in the deployment of the course. From these perspectives, we situate the decision to transfer an existing program across universities, the nuances of …

A Novel Three-Choice Touchscreen Task To Examine Spatial Attention And Orienting Responses In Rodents, Faraj L. Haddad, Maryam Ghahremani, Cleusa De Oliveira, Ella E. Doornaert, Kevin D. Johnston, Stefan Everling, Susanne Schmid

Brain and Mind Institute Researchers' Publications

Mammalian orienting behavior consists of coordinated movements of the eyes, head, pinnae, vibrissae, or body to attend to an external stimulus. The present study aimed to develop a novel operant task using a touch-screen system to measure spatial attention. In this task, rats were trained to nose-poke a light stimulus presented in one of three locations. The stimulus was presented more frequently in the center location to develop spatial attention bias toward the center stimulus. Changes in orienting responses were detected by measuring the animals’ response accuracy and latency to stimuli at the lateral locations, following reversible unilateral chemogenetic inactivation …

Comparing Household And Individual Measures Of Access Through A Food Environment Lens: What Household Food Opportunities Are Missed When Measuring Access To Food Retail At The Individual Level?, Lindsey G. Smith, Michael J. Widener, Bochu Liu, Steven Farber, Leia M. Minaker, Zachary Patterson, Kristian Larsen, Jason Gilliland

Geography & Environment Publications

Geographers and public health researchers have long been interested in social, spatial, and economic factors that drive access and exposure to food retail. A growing body of evidence draws on mobility data to capture locations accessed by individuals beyond the home address. Given that food-related activities are shared by household members and often gendered, taking an individual-level approach might limit researchers’ ability to accurately describe access to food retail. Using data that includes Global Positioning System trajectories of forty-six adults from twenty-one households in Toronto, this study compares access to food retailers at the individual and household levels and evaluates …

Public Health Agencies Outreach Through Instagram During Covid-19 Pandemic: Crisis And Emergency Risk Communication Perspective, Aqdas Malik, Laeeq M. Khan, Anabel Quan-Haase

FIMS Publications

Background: Governmental and non-governmental institutions increasingly use social media as a strategic tool for public outreach. Global spread, promptness, and dialogic potentials make these platforms ideal for public health monitoring and emergency communication in crises such as COVID-19.

Objective: Drawing on the Crisis and Emergency Risk Communication framework, we sought to examine how leading health organizations use Instagram for communicating and engaging during the COVID-19 pandemic.

Methods: We manually retrieved Instagram posts together with relevant metadata of four health organizations (WHO, CDC, IFRC, and NHS) shared between January 1, 2020, and April 30, 2020. Two coders manually coded the analytical …

The Higher Power Of Religiosity Over Personality On Political Ideology, Alexander Ksiazkiewicz, Amanda Friesen

Political Science Publications

Two streams of research, culture war and system justification, have proposed that religious orientations and personality, respectively, play critical roles in political orientations. There has been only limited work integrating these two streams. This integration is now of increased importance given the introduction of behavior-genetic frameworks into our understanding of why people differ politically. Extant research has largely considered the influence of personality as heritable and religiosity as social, but this view needs reconsideration as religiosity is also genetically influenced. Here we integrate these domains and conduct multivariate analyses on twin samples in the U.S. and Australia to identify the …

Promoting And Teaching Responsible Leadership In Software Engineering, Devender Goyal, Luiz Fernando Capretz

Electrical and Computer Engineering Publications

As software and computer technology is becoming more prominent and pervasive in all spheres of life, many researchers and industry folks are realizing the importance of teaching soft skills and values to CS and SE students. Many researchers and leaders, from both academic and non-academic world, are also calling for software researchers and practitioners to seriously consider human values, like respect, integrity, compassion, justice, and honesty when building software, both for greater social good and also for financial considerations. In this paper, we propose and wish to promote teaching soft skills, values, and responsibilities to students, which we term as …

Structural Alterations In Cortical And Thalamocortical White Matter Tracts After Recovery From Prefrontal Cortex Lesions In Macaques, Ramina Adam, David J. Schaeffer, Kevin Johnston, Ravi S. Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

Unilateral damage to the frontoparietal network typically impairs saccade target selection within the contralesional visual hemifield. Severity of deficits and the degree of recovery have been associated with widespread network dysfunction, yet it is not clear how these behavioural and functional brain changes relate with the underlying structural white matter tracts. Here, we investigated whether recovery after unilateral prefrontal cortex (PFC) lesions was associated with changes in white matter microstructure across large-scale frontoparietal cortical and thalamocortical networks. Diffusion-weighted imaging was acquired in four male rhesus macaques at pre-lesion, week 1, and week 8-16 post-lesion when target selection deficits largely recovered. …

Brain and Mind Institute Researchers' Publications

BACKGROUND: Research into numerical cognition has contributed to a large body of knowledge on how children learn and perform mathematics. This knowledge has the potential to inform mathematics education. Unfortunately, numerical cognition research and mathematics education remain disconnected from one another, lacking the proper infrastructure to allow for productive and meaningful exchange between disciplines. The present study was designed to address this gap. AIM: This study reports on the design, implementation, and effects of a 16-week (25-hour) mathematics Professional Development (PD) model for Kindergarten to Grade 3 educators and their students. A central goal of the PD was to better …
