Examining The Role Of Integration Experiences In Shaping Immigrants’ Post-Migration Food Choices And Eating Practices In Ontario, Canada, Eunjeong Eugena Kwon

Electronic Thesis and Dissertation Repository

Despite the extensive literature on immigrants’ post-migration dietary transitions and their implications for long-term health and well-being, little research has been conducted to link these processes to their integration experiences. This dissertation contributes to the current literature by examining the interrelationship between immigrants’ integration experiences – especially their economic integration – and their post-migration food choices and eating practices.

The first integrated article (Chapter 2) draws on qualitative interviews with 38 recent immigrants in two Ontario cities (Toronto and London) in Canada. First, this chapter focuses on illustrating recent immigrants’ general experiences in managing their post-migration food choices and eating …

Resignation Or Resistance? Examining The Digital Privacy Attitudes And Behaviours Of East Yorkers, Kaitlyn Cavacas

Electronic Thesis and Dissertation Repository

Digital technologies have become enmeshed in everyday life causing the public to become exposed to potential privacy risks through data collection and aggregation practices. Further, the upsurge in use of social networking platforms has also created opportunities for privacy violations through institutional and social surveillance. Employing a qualitative thematic analysis, this study explores how adults (N=101) living in East York, Toronto, navigate privacy through their use of the internet and digital services. Participants expressed feelings of mistrust, loss of control, resignation, and perceived self-unimportance with regards to their digital data. Importantly, others noted their desire and attempts to …

Prediction-Based Learning And Processing Of Event Knowledge., Ken Mcrae, Kevin S Brown, Jeffrey L Elman

Psychology Publications

Knowledge of common events is central to many aspects of cognition. Intuitively, it seems as though events are linear chains of the activities of which they are comprised. In line with this intuition, a number of theories of the temporal structure of event knowledge have posited mental representations (data structures) consisting of linear chains of activities. Competing theories focus on the hierarchical nature of event knowledge, with representations comprising ordered scenes, and chains of activities within those scenes. We present evidence that the temporal structure of events typically is not well-defined, but it is much richer and more variable both …

Exploring Cognitive Maps Through Sketching, Melissa M. Nantais

Electronic Thesis and Dissertation Repository

Abstract

Periodic testing has been found to improve the accuracy of participants’ cognitive maps when an onscreen map is provided, however, it is unclear whether the same results would occur without the onscreen map. The current study investigated whether drawing a map periodically while exploring the virtual environment Silcton would improve cognitive map accuracy. Participants explored Silcton and were stopped every 4 minutes to either sketch a map of Silcton, identify items seen in Silcton, or colour an unrelated picture, and a baseline group was not stopped. All groups drew a final sketch map and completed a direction estimation task. …

Examining The Self-Schema Within A Cognitive Vulnerability-Stress Framework Of Mania, Nadia Maiolino

Electronic Thesis and Dissertation Repository

This dissertation aimed to inform a cognitive vulnerability-stress theory of mania, which addresses both the content and structure of the self-schema, along with the conditions under which these self-relevant cognitions are activated. Extant research on mania has primarily considered self-schema content, or an individual’s actual beliefs (e.g., “I am incompetent”). Although these investigations have successfully identified maladaptive self-beliefs associated with bipolar disorder, this research has been prone to inconsistencies and limited in distinguishing between mania and related forms of psychopathology (e.g., unipolar depression). Furthermore, very little research on mania has considered the organization of self-schema beliefs, referred to here as …

Temporalities Of Revolution: On The Representation Of History And Collective Action, Nicholas D. Tostowaryk

Electronic Thesis and Dissertation Repository

This thesis opens with a discussion of Rosa Luxemburg’s notion of “spontaneity,” which departs from a consideration of Luxemburg’s scientific socialism, the inevitability of capitalist collapse, and her assertion of socialism as the objective response to the contradictions of capitalism. For Luxemburg, then, spontaneity refers to the way in which proletarian consciousness forms in response to these conditions. The second chapter argues that Luxemburg’s notion of spontaneity represents what Walter Benjamin would call an historical articulation of the past, which is an articulation of the present and its struggles in terms of their historicity. I develop this argument through a …

Child And Adolescent Sleep Disturbances And Psychopathology In A Mental Health Clinic Sample, Aviva Blacher

Electronic Thesis and Dissertation Repository

Sleep disturbances in children and adolescents (hereafter children) are associated with significant short-term and long-term impairments including more severe psychopathology, reduced cognitive functioning, and poorer general health. We know that children being treated in specialty mental health services are more likely to have sleep disturbances than community samples. We also know that relationships exist between sleep and psychopathology in children with specific disorders (e.g. ADHD, depression, etc.). However, few studies have investigated the relationship between sleep and psychopathology in a broad sample of children seen at mental health agencies. Both child factors and family factors may influence both sleep and …

A Framework For Considering Dissociative Identity Effects In Consumption, Bonnie Simpson, Lea Dunn, Katherine White

Management and Organizational Studies Publications

This chapter examines the mirror image of the identity association principle: dissociation. While the association principle posits that stimuli associated with a positively regarded identity receive more positive evaluations, the dissociation principle suggests that stimuli associated with negatively regarded identities will receive negative evaluations and be abandoned. The authors focus on the nature of dissociative reference groups or groups that the consumer is motivated to avoid association with, and present a framework outlining how dissociative influence can impact consumer behavior. They review the literature on dissociative influence and note that although dissociative reference groups often spur avoidance behaviors, they can …

The Psychosocial Health And Wellbeing Impacts Of Large Scale Land Acquisitions In Coastal Tanzania, Kilian Nasung Atuoye

Electronic Thesis and Dissertation Repository

This dissertation examines the psychosocial health and wellbeing impacts of Large Scale Land Acquisitions (LSLAs) in coastal Tanzania. Contemporary acquisition of large parcels of land in low-income countries by investors is both transformational and a neo-colonization strategy depending on the philosophical frame and scale of analysis. Despite multiple narratives about its impacts across scale, there is consensus in the conceptualization of LSLAs as a global force that is changing local ecologies and communities. Yet, the impact of these changes on the psychosocial health and wellbeing of local populations is less evident. This study employs mixed methods that combines qualitative and …

Narratives Of Canadian Identity At The Ultimate Fighting Championship, Jared V. Walters

Electronic Thesis and Dissertation Repository

The purpose of this dissertation was to examine the use of representations and symbols of Canadian identity within the event coverage produced by the Ultimate Fighting Championship Corporation, in the context of its two key events, Ultimate Fighting Championship, and Fight Night, produced in Canada. To establish the historical context in which the sport developed in Canada, a narrative historiography of the political and legal struggles that led to the legalization and increasing popularity of Mixed Martial Arts, and the UFCC’s version of the sport, in particular. This first major part of the dissertation is contained in Study 1. The …

A Macaque Connectome For Large-Scale Network Simulations In Thevirtualbrain, Kelly Shen, Gleb Bezgin, Michael Schirner, Petra Ritter, Stefan Everling, Anthony R. Mcintosh

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Models of large-scale brain networks that are informed by the underlying anatomical connectivity contribute to our understanding of the mapping between the structure of the brain and its dynamical function. Connectome-based modelling is a promising approach to a more comprehensive understanding of brain function across spatial and temporal scales, but it must be constrained by multi-scale empirical data from animal models. Here we describe the construction of a macaque (Macaca mulatta and Macaca fascicularis) connectome for whole-cortex simulations in TheVirtualBrain, an open-source simulation platform. We take advantage of available axonal tract-tracing datasets and enhance the existing …

Predator-Induced Fear Causes Ptsd-Like Changes In The Brains And Behaviour Of Wild Animals, Liana Y. Zanette, Emma C. Hobbs, Lauren E. Witterick, Scott A. Macdougall-Shackleton, Michael Clinchy

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Predator-induced fear is both, one of the most common stressors employed in animal model studies of post-traumatic stress disorder (PTSD), and a major focus of research in ecology. There has been a growing discourse between these disciplines but no direct empirical linkage. We endeavoured to provide this empirical linkage by conducting experiments drawing upon the strengths of both disciplines. Exposure to a natural cue of predator danger (predator vocalizations), had enduring effects of at least 7 days duration involving both, a heightened sensitivity to predator danger (indicative of an enduring memory of fear), and elevated neuronal …

Consciousness-Specific Dynamic Interactions Of Brain Integration And Functional Diversity, Andrea I. Luppi, Michael M. Craig, Ioannis Pappas, Paola Finoia, Guy B. Williams, Judith Allanson, John D. Pickard, Adrian M. Owen, Lorina Naci, David K. Menon, Emmanuel A. Stamatakis

Brain and Mind Institute Researchers' Publications

Prominent theories of consciousness emphasise different aspects of neurobiology, such as the integration and diversity of information processing within the brain. Here, we combine graph theory and dynamic functional connectivity to compare resting-state functional MRI data from awake volunteers, propofol-anaesthetised volunteers, and patients with disorders of consciousness, in order to identify consciousness-specific patterns of brain function. We demonstrate that cortical networks are especially affected by loss of consciousness during temporal states of high integration, exhibiting reduced functional diversity and compromised informational capacity, whereas thalamo-cortical functional disconnections emerge during states of higher segregation. Spatially, posterior regions of the brain’s default mode …

Altered Motor, Anxiety-Related And Attentional Task Performance At Baseline Associate With Multiple Gene Copies Of The Vesicular Acetylcholine Transporter And Related Protein Overexpression In Chat::Cre+ Rats, Craig P. Mantanona, Johan Alsiö, Joanna L. Elson, Beth M. Fisher, Jeffrey W. Dalley, Timothy Bussey, Ilse S. Pienaar

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Transgenic rodents expressing Cre recombinase cell specifically are used for exploring mechanisms regulating behavior, including those mediated by cholinergic signaling. However, it was recently reported that transgenic mice overexpressing a bacterial artificial chromosome containing choline acetyltransferase (ChAT) gene, for synthesizing the neurotransmitter acetylcholine, present with multiple vesicular acetylcholine transporter (VAChT) gene copies, resulting in altered cholinergic tone and accompanying behavioral abnormalities. Since ChAT::Cre+ rats, used increasingly for understanding the biological basis of CNS disorders, utilize the mouse ChAT promotor to control Cre recombinase expression, we assessed for similar genotypical and phenotypical differences in such rats compared …

Are Specific Learning Disorders Truly Specific, And Are They Disorders?, Lien Peters, Daniel Ansari

Brain and Mind Institute Researchers' Publications

© 2019 The Authors Specific learning disorders, such as dyslexia and dyscalculia, are frequently studied to inform our understanding of cognitive development, genetic mechanisms and brain function. In this Opinion Paper, we discuss limitations of this research approach, including the use of arbitrary criteria to select groups of children, heterogeneity within groups and overlap between domains of learning. By drawing on evidence from cognitive science, neuroscience and genetics, we propose an alternative, dimensional framework. We argue that we need to overcome the problems associated with a categorical approach by taking into account interacting factors at multiple levels of analysis that …

Should It Stay Or Should It Go? Smartphone Dependency, Kira Foreman-Tran, Karina Schnurr, Ana C. Ruiz Pardo, John Paul Minda

Psychology Publications

As smartphones grow in use and popularity, it is important to understand the possible effects that varying levels of smartphone use may have on human cognition. Although smartphones provide many advantages for daily activities, one must also recognize the potential disadvantages. For example, smartphone use may lead to nomophobia, which is defined as the modern fear of not being able to access your smartphone or the internet (Yildirim & Correia, 2015). The present study used a pilot and main study to examine the effects smartphones have on human cognition. The pilot study was conducted to measure nomophobia, mobile phone involvement, …

Disability And Accessibility Language In Subject Headings And Social Tags, Mackenzie Johnson, Carlie Forsythe

FIMS Publications

Mackenzie Johnson and Carlie Forsythe’s article on disability and accessibility language in subject headings and social tagging stresses the importance of involving subject experts in the creation of subject headings, and of getting the headings right to allow effective information retrieval. The authors also assess the ‘third way’, of semi-structured, moderated social tagging systems, that lies between fully controlled vocabularies and free social tagging.

How Do You Solve A Problem Like The Whole User? The Construction Of Worthy And Problematic Users In Online Discussions Of The Public Library, Pam Mckenzie

FIMS Publications

In this article I use a discursive approach and the concept of the ‘category entitlement’ to analyse the ways that contributors to a public Internet discussion of the value of the public library make cases for different user characteristics and behaviour as ‘worthy’ or ‘problematic’, and use these characteristics to discuss and debate the kinds of individuals and the kinds of behaviour that properly belong to each category. Contributors to the discussion represented users in three categories: a fluid ‘everyone’, which included people represented as being disadvantaged and in legitimate need of the library’s resources, expertise, and support; the user …

Exploring The Links Between Social Anxiety And Depression In The Maintenance Of Romantic Relationships, Christian M. Hahn

Electronic Thesis and Dissertation Repository

Social anxiety is characterized by fear and avoidance of social encounters and has recently been associated with a variety of difficulties in romantic relationships. Complicating further investigation of these associations is the high degree of comorbidity between social anxiety and depressive symptomatology, which share several similarities in expression despite disparate underlying causes. The present thesis examines the unique influences of social anxiety and depression on a number of central aspects of relationship functioning and provide the first longitudinal investigation of the impacts of actor and partner social anxiety and depression on relationship quality and functioning. In Study 1, three independent …

Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic

Electronic Thesis and Dissertation Repository

Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …

Exploring The Occupational History Of The Middle Ontario Iroquoian Dorchester Village Site, Johnathan Freeman

Electronic Thesis and Dissertation Repository

Intrasite trends in superposition and spatial arrangements of longhouses, features and palisades, in conjunction with seriation of ceramic vessels, are used to explore the developmental history of the Dorchester Village site, a complex Late Woodland Middle Ontario Iroquoian archaeological village site, as a case study of intrasite seriation. Vessel attributes were coded and subject to correspondence analysis to seek plausible temporal sequences. The Brainerd Robinson coefficient of similarity was used to identify plausible temporal phase groups of longhouses by comparison of vessels attributed to specific houses. Multiple ceramic attributes were explored, and the attribute of upper rim motif generated the …

A Developmental And Symptom-Level Approach To Comorbid Mental Health Disorders In Children, Elizabeth Thornley

Electronic Thesis and Dissertation Repository

This dissertation addresses current issues in the conceptualization and classification of childhood mental health issues (e.g., impact of sex/age on symptoms, comorbidity, limits of traditional models). In contrast to traditional models, the importance and value of utilizing individual symptoms as primary variables of interest is presented. This first study consisted of 9565 participants (M = 12.06, SD = 3.57, 58% males). Results for youth with no history of trauma indicated sex differences in symptom expression consistent with what has been previously shown in the literature; however, a complex presentation of attention-related symptoms was identified for females. Similar sex differences …

The Role Of Social Disconnection In The Relationship Between Perfectionism And Psychological Distress, Samantha Chen

Electronic Thesis and Dissertation Repository

This dissertation investigated the interpersonal mechanisms through which various aspects of perfectionism confer risk for psychological outcomes. Three studies were conducted based on the Perfectionism Social Disconnection Model (Hewitt, Flett, & Mikail, 2017), which proposes that individuals with higher levels of perfectionism may experience significant social disconnection, which then lead to a variety of maladaptive outcomes. Study 1 examined the longitudinal impacts of trait perfectionism and sense of relatedness on the variance in change in psychological outcomes. Findings showed that negative perceptions of relatedness partially mediated the link between socially prescribed perfectionism and psychological distress three months later; however, this …

Functional Localization Of The Frontal Eye Fields In The Common Marmoset Using Microstimulation, Janahan Selvanayagam, Kevin D. Johnston, David J. Schaeffer, Lauren K. Hayrynen, Stefan Everling

Brain and Mind Institute Researchers' Publications

Copyright © 2019 the authors. The frontal eye field (FEF) is a critical region for the deployment of overt and covert spatial attention. Although investigations in the macaque continue to provide insight into the neural underpinnings of the FEF, due to its location within a sulcus, the macaque FEF is virtually inaccessible to electrophysiological techniques such as high-density and laminar recordings. With a largely lissencephalic cortex, the common marmoset (Callithrix jacchus) is a promising alternative primate model for studying FEF microcircuitry. Putative homologies have been established with the macaque FEF on the basis of cytoarchitecture and connectivity; however, physiological investigation …

Preventing Adolescent Dating Violence: An Outcomes Protocol For Evaluating A Gender-Transformative Healthy Relationships Promotion Program, Deinera Exner-Cortens, Alysia Wright, Debb Hurlock, Roseline Carter, Pam Krause, Claire Crooks

Journal Articles

Adolescent dating violence (ADV) is a pressing public health problem in North America. Strategies to prevent perpetration are needed, and a substantial body of research demonstrates the importance of applying a gender lens to target root causes of adolescent dating violence as part of effective prevention. To date, however, there has been limited research on how to specifically engage boys in adolescent dating violence prevention. In this short communication, we describe the protocol for a longitudinal, quasi-experimental outcome evaluation of a program called WiseGuyz. WiseGuyz is a community-facilitated, gender-transformative healthy relationships program for mid-adolescent male-identified youth that aims to reduce …

Comparative Assessment Of Downscaling Methods And Application Towards Analysis Of Climate Change Impact On Urban Regions, Markus Eichenbaum

Electronic Thesis and Dissertation Repository

Global climate models (GCM) are sophisticated numerical models used to make long term climate projections. However, the resolution of their output is too coarse for climate change related local impact studies on urban regional scales. Downscaling efforts are taken to address this and increase GCM projection resolution. Physical Scaling (SP) downscaling methodology attempts to incorporate the physical basis of dynamical downscaling efforts with the computational efficiency of statistical methods. In this study, North American Regional Reanalysis surface skin temperature and precipitation data for a 1°x1° region centered on Houston, TX are downscaled to a resolution of 500m via SP and …
