Sign And Speech Share Partially Overlapping Conceptual Representations, Samuel Evans, Cathy J. Price, Jörn Diedrichsen, Eva Gutierrez-Sigut, Mairéad Macsweeney

Brain and Mind Institute Researchers' Publications

© 2019 The Author(s) Conceptual knowledge is fundamental to human cognition. Yet, the extent to which it is influenced by language is unclear. Studies of semantic processing show that similar neural patterns are evoked by the same concepts presented in different modalities (e.g., spoken words and pictures or text) [1–3]. This suggests that conceptual representations are “modality independent.” However, an alternative possibility is that the similarity reflects retrieval of common spoken language representations. Indeed, in hearing spoken language users, text and spoken language are co-dependent [4, 5], and pictures are encoded via visual and verbal routes [6]. A parallel approach …

Adaptation To Conflict Frequency: Non-Conflict Learning Is Not The Whole Story, Giacomo Spinelli

Electronic Thesis and Dissertation Repository

In the Stroop task, smaller congruency effects (i.e., the color-naming difference between incongruent items, e.g., the word RED in the color blue, and congruent items, e.g., RED in red) are found in conditions in which incongruent items are frequent vs. infrequent. Although the traditional explanation for these “Proportion-Congruent effects” is that attention to task-relevant information is more focused in frequently-conflicting conditions (a process involving adaptation to conflict frequency), Proportion-Congruent paradigms typically have not controlled for the impact of more general learning processes, particularly 1) learning of word-response contingencies (contingency learning), 2) learning about the predictive nature of the stimuli (stimulus …

Variational Representational Similarity Analysis, Karl J. Friston, Jörn Diedrichsen, Emma Holmes, Peter Zeidman

Brain and Mind Institute Researchers' Publications

© 2019 The Authors This technical note describes a variational or Bayesian implementation of representational similarity analysis (RSA) and pattern component modelling (PCM). It considers RSA and PCM as Bayesian model comparison procedures that assess the evidence for stimulus or condition-specific patterns of responses distributed over voxels or channels. On this view, one can use standard variational inference procedures to quantify the contributions of particular patterns to the data, by evaluating second-order parameters or hyperparameters. Crucially, this allows one to use parametric empirical Bayes (PEB) to infer which patterns are consistent among subjects. At the between-subject level, one can then …

Local Government Responses To Festivals: An Exploratory Study, Andrew Grozelle

MPA Major Research Papers

This study explores the dynamics of ‘bottom-up’ policymaking at the municipal level by analyzing the policy response of the local government to unsanctioned events, such as the annual Port Dover Friday the 13th Motorcycle Festival (PD13) from May 1981 to November 2019. Using this event as a case study, the project seeks to answer the following questions: what has been the local government’s policy approach to PD13? What factors explain this approach and are there alternative approaches to the one chosen? To answer these questions, the paper adopts a multi-method research strategy, which involved a historical review of relevant literature, …

The Successful Implementation Of O. Reg. 588/17: Organizational Factors That Contribute To The Success Of Asset Management Planning For Municipal Infrastructure In Small Ontario Municipalities, Jenna Campbell (Shultz)

MPA Major Research Papers

Asset management planning in Ontario has evolved since the early 2000s and Ontario Regulation 588/17: Asset Management Planning for Municipal Infrastructure came into effect on January 1, 2019. The requirements of the regulation are different for small municipalities, being those having a population of less than 25,000, than for large municipalities. The burden of undertaking large-scale change initiatives, specifically those that are externally initiated, can be especially difficult for small municipalities that often lack the resources and specialized staff to address these changes. This paper explores the organizational factors that contribute to the success of local government asset management planning …

Peer Coaching For Leadership Development In The Public Sector: A Case Study From Local Public Health, Tammy Mackinnon

MPA Major Research Papers

Leadership development is critical for the future of public sector organizations. Its impact on employee satisfaction, collaboration and organizational performance has been well documented. But how do we best develop leadership in the public sector? Trends in the literature call for a shift to more shared, distributed approaches which argue that leadership capacity is necessary at all organizational levels, regardless of positional authority. This study will examine the efficacy of a peer coaching model at imbedding leadership capacity throughout the layers of an organizational structure. Using a case study of leadership development in local public health, this study contributes to …

This brief aims to inform potential action in view of two significant developments in Canada’s international assistance strategy — the $400 million commitment to girls’ and women’s education in response to the Charlevoix Declaration on Quality Education for Girls, Adolescent Girls and Women in Developing Countries and the strategy for engaging in private sector partnerships in the Feminist International Assistance Policy. The brief is based on original analysis of data on activity by private foundations and private sector impact investors in girls’ and women’s education in East Asia and the Pacific and South Asia, drawing on a larger regional-level …

Cognitive Change In Cognitive-Behavioural Therapy, Leanne Quigley, David J A Dozois, R Michael Bagby, Daniela S S Lobo, Lakshmi Ravindran, Lena C Quilty

Psychology Publications

BACKGROUND: Although cognitive-behavioural therapy (CBT) is a well-established treatment for adult depression, its efficacy and efficiency may be enhanced by better understanding its mechanism(s) of action. According to the theoretical model of CBT, symptom improvement occurs via reductions in maladaptive cognition. However, previous research has not established clear evidence for this cognitive mediation model.

METHODS: The present study investigated the cognitive mediation model of CBT in the context of a randomized controlled trial of CBT v. antidepressant medication (ADM) for adult depression. Participants with major depressive disorder were randomized to receive 16 weeks of CBT (n = 54) or ADM …

Essays On College Majors And Skills, Yuki Onozuka

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters that study relationships between college majors and multi-dimensional skills.

Chapter 2 examines the sources of wage penalties for working outside one's major field of study. Previous papers show that workers in a job which is unrelated to their major field of study tend to earn significantly lower wages than those in a related job. I use the 1993 National Survey of College Graduates and the O*NET to divide the sources of wage penalty into the levels of basic skills required in a job and the mismatch in major-specific knowledge. I find that the average …

A Sound-Sensitive Source Of Alpha Oscillations In Human Non-Primary Auditory Cortex, Alexander J. Billig, Björn Herrmann, Ariane E. Rhone, Phillip E. Gander, Kirill V. Nourski, Beau F. Snoad, Christopher K. Kovach, Hiroto Kawasaki, Matthew A. Howard, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

Copyright © 2019 Billig, Herrmann et al. The functional organization of human auditory cortex can be probed by characterizing responses to various classes of sound at different anatomical locations. Along with histological studies this approach has revealed a primary field in posteromedial Heschl's gyrus (HG) with pronounced induced high-frequency (70-150 Hz) activity and short-latency responses that phase-lock to rapid transient sounds. Low-frequency neural oscillations are also relevant to stimulus processing and information flow, however, their distribution within auditory cortex has not been established. Alpha activity (7-14 Hz) in particular has been associated with processes that may differentially engage earlier versus …

South Bend And Ridge Pine 2: Fraternal Twins, Gabryell Kurtzrock Belyea

Electronic Thesis and Dissertation Repository

The Ridge Pine 2 and South Bend sites lie within four kilometres of each other, both date to the late Middle Archaic period (ca. 5500-4500 before present), and both contain significant amounts of nonlocal chert. This exploitation of nonlocal chert occurred despite the close proximity of the Kettle Point chert outcrop to both sites. Notwithstanding their similarities, the two sites differ dramatically. From the raw material breakdown to projectile point types the two assemblages are quite different. These differences raise questions surrounding the chert procurement strategy employed by the groups at Ridge Pine 2 and South Bend. In order to …

Behind Quality, There Is Equality: An Analysis Of Scientific Capital Accumulation In Social-Democratic Welfare Regimes, Olivier Bégin-Caouette

Comparative and International Education / Éducation Comparée et Internationale

ABSTRACT

Trade-offs between quality and equality are at the forefront of multiple debates in higher education, and one conceptual tool to approach societies’ adjustment in resolving these trade-offs is the welfare regime typology. Relying on the theory of academic capitalism and using research production as a proxy for quality in higher education, this study analyses how social-democratic welfare regimes resolve the trade-off between comparatively high levels of academic research production, access to higher education and equal citizens’ living conditions. Interviews with 56 system actors suggest that equality is perceived to contribute to academic freedom, public investments in research and the …

Critical Pedagogy Of Discomfort In Community-Based Learning: Kenyan Students' Experiences, Charlene A. Vanleeuwen, Lori E. Weeks, Linyuan Guo-Brennan

Comparative and International Education / Éducation Comparée et Internationale

Community-based learning (CBL) is employed as a pedagogical approach in professional programs globally; however, transferability of Eurocentric CBL models and theory to university settings outside the global north is under-examined. Adopting critical hermeneutics as the theoretical and methodological framework, this study explored the meaning of community-based learning (CBL) to Kenyan university students in a human services program and examined the complexity of students’ difficult learning experiences in making connections between classroom learning and praxis in Kenyan communities. Data were collected from six university students following 12-week placements with community organizations in Kenya. Findings revealed disciplinary, historical, cultural and extra-linguistic factors …

Death Of The Clinic: Trans-Informing The Clinical Gaze To Counter Epistemic Violence, Diana E. Kuhl

Electronic Thesis and Dissertation Repository

This case study research (Patton, 2002, 2014; Flyvberg, 2006) has grown out of an awareness of deep resistance from the psy disciplines to trans-informed epistemologies as a source of legitimate knowledge (Tosh, 2015, 2016; Winters, 2008). It focuses on examining how the closure of The Gender Identity Clinic (GIC) for Children and Youth at the Centre for Addiction and Mental Health (CAMH) in Toronto, Ontario, Canada, signaled a paradigm shift from the ‘treatment model’ to the ‘affirmative model’ with respect to clinical approaches for supporting trans and gender diverse children and youth. As such the case study involved tracing the …

Rethinking Gentrification And Eviction In Toronto: Are Homes Still Built For Living?, Keefer Wong

Electronic Thesis and Dissertation Repository

The significant increase in evictions has become one of the foremost manifestations of the housing crisis in gentrifying cities. However, the lack of collected data at both the provincial and federal levels has made it difficult to assess the distribution and conceptual nuances of this phenomenon in urban cities like Toronto. The current study explores the newer ways in which eviction is used in gentrifying cities and illustrates how any renter, not just the “urban poor,” can be precariously placed. For this purpose, eviction data drawn from the Social Justice Tribunals Ontario was used to explore how evictions were spaced …

Assessing Self-Identified And Meta-Perceived Social Groups For Predicting Day-To-Day Discrimination And Examining Psychological Distress Based On Identity Mismatch, Emily C. Nunez

Electronic Thesis and Dissertation Repository

The way that people are socially assigned may influence how they are targeted for discrimination. Whether self-identified (SI) or meta-perceived (MP) (i.e. perceptions of how one is classified by others) and visibly expressed (VE) (e.g. clothing) social identity better predict day-to-day discrimination is an important question that has not been addressed in previous research. Identity mismatch based on SI and MP social groups may cause psychological distress, and racial ambiguity may contribute to ethnoracial identity mismatch. This thesis utilized a cross-sectional survey conducted in Canada and the United States to assess how levels of day-to-day discrimination varied based on SI …

The Economic Integration Of Mexican Mennonite Immigrants In Canada, Marina Wiebe

MA Research Paper

With a rapidly shrinking proportion of Canadians that live in rural areas, there have been some attempts to settle immigrants in rural communities. With few exceptions, these attempts in Canada have been unsuccessful. Nevertheless, the Mennonite people are considered to be a population that maintains their retention in rural areas with some success. The literature regarding this specific immigrant group is limited and lacks context of the economic environment of Canada today. It is in the interest of government policy to have a working and current understanding of Mennonites’ economic outcomes and retention in rural communities. The integration patterns of …

An App A Day Keeps The Doctor Away: A Visual Case Analysis Of The Self-Optimization Ideologies Downloaded Onto Apple Users As They Download Applications, Ismahan Yusuf

MA Research Paper

This visually thematic qualitative case analysis seeks to advance cyber-sociology by analyzing the hyper-under-attended relationship between interfaces and discourses. Here, the interface under investigation is the Apple App Store, examined for the ways in which the platform is discursively encoded with particular ideologies, ideals, desires and narratives downloaded onto users as they download applications. Such is explored via a two-part research question inquiring: Which type of applications enjoy the most promotion on the Apple App Store and what cyber-architectural tools are herein used to optically exalt them? To investigate this, an iOS 11-operating iPhone was used to frequent the store’s …

An Accurate Registration Of The Bigbrain Dataset With The Mni Pd25 And Icbm152 Atlases., Yiming Xiao, Jonathan C Lau, Taylor Anderson, Jordan Dekraker, D Louis Collins, Terry Peters, Ali R Khan

Brain and Mind Institute Researchers' Publications

Brain atlases that encompass detailed anatomical or physiological features are instrumental in the research and surgical planning of various neurological conditions. Magnetic resonance imaging (MRI) has played important roles in neuro-image analysis while histological data remain crucial as a gold standard to guide and validate such analyses. With cellular-scale resolution, the BigBrain atlas offers 3D histology of a complete human brain, and is highly valuable to the research and clinical community. To bridge the insights at macro- and micro-levels, accurate mapping of BigBrain and established MRI brain atlases is necessary, but the existing registration is unsatisfactory. The described dataset includes …

In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber

Electronic Thesis and Dissertation Repository

In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …

Trial By Space: Lost Cause Monuments And Public Controversy Through Bruno Latour And Henri Lefebvre, Wil Patrick

Electronic Thesis and Dissertation Repository

This thesis is a discussion of the discourse monuments erected by Neo-Confederate organizations on Monument Avenue in Richmond, Virginia through the political work of Bruno Latour and Henri Lefebvre. In response to framing the controversy surrounding monuments as conflicts over historical interpretation, this thesis asks how re-orienting the Confederate monument controversy through the intersection of Latour and Lefebvre’s theorization of politics and monumentality alter the approach to addressing Lost Cause spaces. My first chapter addresses the current framing of the controversy as one of imbalanced narratives, where a pedagogical solution is proposed to educate and contextualize Confederate statues. In my …

Promoting Mentally Healthy Classrooms: Evaluation Of Online Mental Health Literacy Instruction In Pre-Service Teacher Education, E. Robyn Masters

Electronic Thesis and Dissertation Repository

To better understand how to prepare large numbers of pre-service teachers for their role in creating and leading mentally healthy classrooms, this program evaluation explores outcomes related to an online mental health literacy course at a large central Canadian university. The course was delivered to 275 teacher education students simultaneously over 10-weeks and 20-hours of online instruction and professional reflection. Results indicated significant improvement in self-reported levels of mental health literacy, stigma toward mental illness, and self-efficacy for teaching students with diverse challenges. Qualitative reviews of participant feedback identified the most valuable aspects of the course and the ways in …

How Do Humans Process Magnitudes? An Examination Of The Neural And Cognitive Underpinnings Of Symbols, Quantities, And Size In Adults And Children, Helen Moriah Sokolowski

Electronic Thesis and Dissertation Repository

A striking way that humans differ from other species is our unique ability to represent and manipulate symbols. This ability to process numerical magnitudes symbolically (e.g., ‘three’, ‘3’) is widely thought to be supported by an ancient system that evolved to process nonsymbolic numerical magnitudes (i.e., quantities). In this thesis, I present four empirical studies to uncover whether symbolic representations are indeed supported by the system that evolved to process quantities, or if symbolic representations are sub-served by a similar but ultimately distinct system.

In experiments 1 and 2, I investigate how the adult brain processes symbols and quantities using …

Demystifying Wikipedia, Alie Visser, Erin Johnson

Western Libraries Presentations

Wikipedia: we all know it, and we all use it. As the 5th most visited website in the world, the English version of Wikipedia was viewed 92 billion times last year. Yet, in its short history, libraries have historically stigmatized this resource for its crowd-sourced editing system and inconsistent source quality. Increasingly, librarians from around the world are collaborating with Wikimedia to improve its authority by linking to open resources, hosting edit-a-thons, and integrating our organizational structures into Wikidata. In this workshop, we will highlight the power of the platform, the overlapping values of libraries and Wikipedia, and how both …

Development And Application Of A Teen-Informed Tool For Measuring The Power Of Food-Related Advertisements In Canadian Environments, Drew Bowman

Electronic Thesis and Dissertation Repository

Food environments are influential in shaping dietary behaviours of adolescents. Exposure to food and beverage marketing is known to impact food knowledge, behaviours, and health outcomes, yet food environment research largely overlooks advertisements. Given that marketers tend to advertise less healthy foods to teens and teens predominantly purchase low-nutrient foods, it is crucial to study the information environment in the context of secondary school environments. This thesis uses a sequential mixed-methods approach, including environmental audits and teen consultations, to develop and apply a teen-informed tool to measure the power of advertisements surrounding secondary schools. Results indicate that exposure to and …

How Does The Brain Represent Digits? Investigating The Neural Correlates Of Symbolic Number Representation Using Fmri-Adaptation, Celia Goffin

Electronic Thesis and Dissertation Repository

How does the brain represent numerical symbols (e.g., Arabic digits)? Activity in left parietal regions correlates with symbolic number processing. Research with functional resonance imaging adaptation (fMRI-A) indicates that the intraparietal sulcus (IPS) exhibits a rebound (increase in activation) effect when a repeatedly presented number is followed by a new number. Importantly, this rebound effect is modulated by numerical ratio as well as the difference between presented numbers (distance). This ratio-dependent rebound effect could reflect a link between symbolic numerical representation and an approximate number system (ANS). In this doctoral dissertation, fMRI-A is used to investigate mechanisms underlying symbolic number …

Adolescents’ Perceptions And Responses To Peer Mental Health Challenges And Problematic Behaviours Following A Social-Emotional Learning Program, Jessica Sommers

Electronic Thesis and Dissertation Repository

Vulnerable youth may be more susceptible to developing problematic behaviours and mental health challenges, including anxious and depressive symptoms, suicidal ideation, substance misuse, and unhealthy relationships. Social-emotional learning programs like The Healthy Relationships Plus Program (HRPP) can foster positive youth development by including training on mental health literacy, developing skills in help-seeking, and providing opportunities to practice difficult conversations. This study explored youth’s responses to hypothetical challenges faced by peers with a group of sixty-three adolescents who had participated in the HRPP. Responses to four distinct scenarios were collected to examine youths’ perceptions of various challenges and problematic behaviours, including …

Response Of Stream Biofilm Function To Pulsed Increases In Velocity And Nutrients: An Artificial Stream Study, Chris Lucas

Electronic Thesis and Dissertation Repository

Pulsed increases in flow within streams alter abiotic conditions such as nutrient concentrations and velocity which can influence the function of stream ecology, including biofilms. A 31-day artificial stream experiment at Thames River Experimental Stream Sciences (TRESS) Centre, London, Ontario, assessed the response of stream biofilm function (decomposition, primary production, community respiration) to individual and combined increases in velocity and phosphorus associated with a 48-hour hydrological pulse event. There was some evidence of an interactive subsidy effect of increased phosphorus and velocity on algal productivity. Decomposition increased as a result of increased phosphorus but there was no synergistic interaction of …

Interrogating Discourses Of Global Education: Reconceptualizing Education As A Common Good?, Prachi Srivastava

Education Publications

This contribution analyses UNESCO's framework of education as a common good in the context of the Global South. It argues that dominant conceptions view education in a narrow, instrumentalist perspective. Despite its promise to reorient education as a broader social endeavour towards human wellbeing to lead meaningful lives (Sen, 1999), UNESCO's framework has failed to gain significant traction. I argue this is linked to challenges associated with: education and unemployment; global mobility and learning assessment systems; citizenship education; and the global governance of education policymaking.

A Framework For Evaluating Correspondence Between Brain Images Using Anatomical Fiducials., Jonathan C Lau, Andrew G Parrent, John Demarco, Geetika Gupta, Jason Kai, Olivia W Stanley, Tristan Kuehn, Patrick J Park, Kayla Ferko, Ali R Khan, Terry M Peters

Brain and Mind Institute Researchers' Publications

Accurate spatial correspondence between template and subject images is a crucial step in neuroimaging studies and clinical applications like stereotactic neurosurgery. In the absence of a robust quantitative approach, we sought to propose and validate a set of point landmarks, anatomical fiducials (AFIDs), that could be quickly, accurately, and reliably placed on magnetic resonance images of the human brain. Using several publicly available brain templates and individual participant datasets, novice users could be trained to place a set of 32 AFIDs with millimetric accuracy. Furthermore, the utility of the AFIDs protocol is demonstrated for evaluating subject-to-template and template-to-template registration. Specifically, …
