Differential Responses To Constraints On Naming Agency Among Indigenous Peoples And Immigrants In Canada, Karen E. Pennesi

Anthropology Publications

This article illuminates the social structures and relations that shape agency for members of two marginalized groups in Canada and examines how individuals respond differently to constraints on their power to name themselves and their children. Constraints on spelling, structure and choice of name are framed according to the particular positions of indigenous peoples and immigrants in relation to European settler society as either ‘original inhabitants’ or ‘recent arrivals’. These historically unequal power relations are manifest in intertwined ideologies of language, identity and nation, evident in ethnographic interviews, media reports and online commentary. Differential responses include resistance, endurance and assimilation.

Debating Student Privacy In Library Research Projects Paper, Jennifer Mayer, Rachel Dineen

University Libraries Publications

As pressure increases for librarians and administrators to demonstrate the value of academic libraries, there is a parallel concern regarding student data privacy in terms of learning analytics and other data tracking methods used by universities. The intersection where demonstrating the value of academic libraries meets student privacy is a crucial, controversial, and timely debate for our profession. This contributed paper provides an overview of the debate about student privacy and library research projects, a discussion of the evolution of our study, the next steps we will take as a result of our work, and recommendations for others who aspire …

Multimodal Event Knowledge In Online Sentence Comprehension: The Influence Of Visual Context On Anticipatory Eye Movements, Valentina Benedettini, Pier Marco Bertinetto, Alessandro Lenci, Ken Mcrae

Psychology Publications

People predict incoming words during online sentence comprehension based on their knowledge of real-world events that is cued by preceding linguistic contexts. We used the visual world paradigm to investigate how event knowledge activated by an agent-verb pair is integrated with perceptual information about the referent that fits the patient role. During the verb time window participants looked significantly more at the referents that are expected given the agent-verb pair. Results are consistent with the assumption that event-based knowledge involves perceptual properties of typical participants. The knowledge activated by the agent is compositionally integrated with knowledge cued by the verb …

Individual Differences In Cognitive Map Accuracy: Investigating The Role Of Landmark Familiarity, Nicole L. Youngson, Megan Vollebregt, Jennifer Sutton

Psychology Publications

Broad individual differences exist in the ability to create a cognitive map of a new environment. The current studies investigated whether familiarizing participants with to-be-learned target landmarks (Experiment 1) or target landmarks plus the order they would be encountered along routes (Experiment 2) before exploring the Silcton virtual environment would increase performance on tasks assaying spatial memory of Silcton. Participants in both experiments were randomly assigned to be pre-exposed either to information about target landmarks in Silcton or control landmarks on the university campus. In both experiments, participants explored Silcton via four prescribed routes and then performed a direction estimation …

A Randomized Controlled Trial Of Internet-Delivered Cbt And Attention Bias Modification For Early Intervention Of Depression, R. Mcdermott, David J. A. Dozois

Psychology Publications

Abstract

The conceptualization and empirical knowledge base related to major depression has increased dramatically in recent years. We now have well-developed and validated models of depression from a range of theoretical perspectives. These models have significantly enhanced the development of effective treatments and preventative interventions. Although various prevention programs are available, Web-based protocols can enhance accessibility to evidence-based prevention programs. The current study involved a randomized controlled trial focused on the prevention and treatment of depression in high-risk first- and second-year undergraduate students. Three Internet-delivered preventative programs were compared: cognitive behavioral therapy (CBT; MoodGym), attentional bias modification, and an active …

Quasi-Factives And Cognitive Efficiency, Axel Barcelo Aspeitia, Robert Stainton

Philosophy Publications

We introduce the notion of a "quasi-factive" -- sentences such as 'It isn't widely known that Obama has been arrested', which is true because he hasn't been arrested -- and offer an explanation of why we hear them as if they were factives.

Generational Change? The Effects Of Family, Age, And Time On Moral Foundations, Amanda Friesen

Political Science Publications

One way to uncover the persistent role of religion across generations is to look past traditional understandings of religious belief and denominational belonging and examine the presence of bedrock principles that could influence political beliefs in families. The Moral Foundations framework was developed for this purpose – to describe human behavior and attitudes in the moral realm without relying upon country, culture, or time specific labels. In an original and rare three-generation dataset, college students, their parents, and their grandparents were asked about political attitudes and preferences for the Moral Foundations of Harm/Care, Fairness/Reciprocity, Ingroup/Loyalty, Authority/Respect, and Purity/Sanctity. The Foundations …

Digital Segregation: Gender, Occupation, And Access To Politics, Amanda Friesen, Ryan Burge, Kylee Britzman

Political Science Publications

In the United States, women often show less interest in politics, and under some conditions, perform worse than men on political knowledge tests. In an age where education levels have reached parity, we suggest one of the explanations for gender differences in political engagement might be due to selection of occupation. Past research has shown women and men segregate into different occupations due to early gender socialization, differences in interest, and structural barriers. It is possible that due to these segregation effects, women in traditional female occupations (e.g., education, health care, service work) may have less access to personal Internet …

To conclude, I present a series of recommendations and valuable resources for librarians and enthusiasts.

Just-In-Time Or Just-In-Case? Time, Learning Analytics, And The Library, Karen P. Nicholson, Nicole Pagowsky, Maura Seale

FIMS Publications

In this essay, we explore the timescapes of library learning analytics. We contend that just-in-time strategies, a feature of late capital modes of production, New Public Management, and future-oriented risk-management strategies inform the adoption of learning analytics. Learning analytics function as a form of temporal governmentality: current performance is scrutinized in order to anticipate future performance and prescribe just-in-time interventions to mitigate risk—not only for the student but also for the institution. Ultimately, we argue that using time as a lens to examine discourses surrounding library learning analytics reveals the temporalities reproduced in this discourse, which obscures questions of power, …

Eros In The Library: Considering The Aesthetics Of Knowledge Organization, Melissa Adler

FIMS Publications

Privileging the aesthetic aspects of knowledge organization through a feminist historical lens may open possibilities for reimagining a library’s space. This paper reveals the history of a relatively unknown figure in the history of knowledge organization. I will suggest that we might regard Pamphila, a miscellanist who lived in Greece during the 1st century, as a ‘radical cataloguer’ who introduced amethod associated with weaving and embroidery. Her organizational method privileged beauty and pleasure, along with historical accuracy and usefulness.

Investigating The Visual Number Form Area: A Replication Study, Rebecca Merkley, Benjamin Conrad, Gavin Price, Daniel Ansari

Brain and Mind Institute Researchers' Publications

© 2019 The Authors. Published by the Royal Society The influential triple-code model of number representation proposed that there are three distinct brain regions for three different numerical representations: verbal words, visual digits and abstract magnitudes. It was hypothesized that the region for visual digits, known as the number form area, would be in ventral occipitotemporal cortex (vOTC), near other visual category-specific regions, such as the visual word form area. However, neuroimaging investigations searching for a region that responds in a category-specific manner to the visual presentation of number symbols have yielded inconsistent results. Price & Ansari (Price, Ansari 2011 …

Translational Tests Involving Non-Reward: Methodological Considerations, Benjamin U. Phillips, Laura Lopez-Cruz, Lisa M. Saksida, Timothy J. Bussey

Brain and Mind Institute Researchers' Publications

© 2018, The Author(s). This review is concerned with methods for assessing the processing of unrewarded responses in experimental animals and the mechanisms underlying performance of these tasks. A number of clinical populations, including Parkinson’s disease, depression, compulsive disorders, and schizophrenia demonstrate either abnormal processing or learning from non-rewarded responses in laboratory-based reinforcement learning tasks. These effects are hypothesized to result from disturbances in modulatory neurotransmitter systems, including dopamine and serotonin. Parallel work in experimental animals has revealed consistent behavioral patterns associated with non-reward and, consistent with the human literature, modulatory roles for specific neurotransmitters. Classical tests involving an important …

White Matter Injury Predicts Disrupted Functional Connectivity And Microstructure In Very Preterm Born Neonates, Emma G. Duerden, Sheliza Halani, Karin Ng, Ting Guo, Justin Foong, Torin J.A. Glass, Vann Chau, Helen M. Branson, John G. Sled, Hilary E. Whyte, Edmond N. Kelly, Steven P. Miller

Brain and Mind Institute Researchers' Publications

© 2018 The Authors Objective: To determine whether the spatial extent and location of early-identified punctate white matter injury (WMI) is associated with regionally-specific disruptions in thalamocortical-connectivity in very-preterm born neonates. Methods: 37 very-preterm born neonates (median gestational age: 28.1 weeks; interquartile range [IQR]: 27–30) underwent early MRI (median age 32.9 weeks; IQR: 32–35), and WMI was identified in 13 (35%) neonates. Structural T1-weighted, resting-state functional Magnetic Resonance Imaging (rs-fMRI, n = 34) and Diffusion Tensor Imaging (DTI, n = 31) sequences were acquired using 3 T-MRI. A probabilistic map of WMI was developed for the 13 neonates demonstrating brain …

Girls' Internalizing Symptoms And White Matter Tracts In Cortico-Limbic Circuitry, Ola Mohamed Ali, Matthew R.J. Vandermeer, Haroon I. Sheikh, Marc F. Joanisse, Elizabeth P. Hayden

Brain and Mind Institute Researchers' Publications

© 2019 The Authors Dysfunction in cortico-limbic circuitry is implicated in internalizing disorders (i.e., depressive and anxious disorders), but less is known about whether structural variations precede frank disorder and thus potentially mark risk. We therefore examined associations between white matter (WM) tract microstructure in cortico-limbic circuitry at age 7 and concurrent and longitudinal patterns of internalizing symptoms in 42 typically developing girls using Diffusion Tensor Imaging (DTI). Girls' internalizing symptoms were concurrently associated with reduced fractional anisotropy (FA) in segments of the cingulum bundle (CB) and the uncinate fasciculus (UF), bilaterally. Moreover, latent profile analysis showed that girls with …

The Benefit To Speech Intelligibility Of Hearing A Familiar Voice, Ysabel Domingo, Emma Holmes, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

© 2019 American Psychological Association. Previous experience with a voice can help listeners understand speech when a competing talker is present. Using the coordinate-response measure task (Bolia, Nelson, Ericson, & Simpson, 2000), Johnsrude et al. (2013) demonstrated that speech is more intelligible when either the target or competing (masking) talker is a long-term spouse than when both talkers are unfamiliar (termed familiar-target and familiar-masker benefits, respectively). To better understand how familiarity improves intelligibility, we measured the familiar-target and familiar-masker benefits in older and younger spouses using a more challenging matrix task, and compared the benefits listeners gain from spouses' and …

Biomarkers Of Parkinson's Disease: Striatal Sub-Regional Structural Morphometry And Diffusion Mri, Ali R. Khan, Nole M. Hiebert, Andrew Vo, Brian T. Wang, Adrian M. Owen, Ken N. Seergobin, Penny A. Macdonald

Brain and Mind Institute Researchers' Publications

© 2018 The Authors Parkinson's disease (PD) is a progressive neurological disorder that has no reliable biomarkers. The aim of this study was to explore the potential of semi-automated sub-regional analysis of the striatum with magnetic resonance imaging (MRI) to distinguish PD patients from controls (i.e., as a diagnostic biomarker) and to compare PD patients at different stages of disease. With 3 Tesla MRI, diffusion- and T1-weighted scans were obtained on two occasions in 24 PD patients and 18 age-matched, healthy controls. PD patients completed one session on and the other session off dopaminergic medication. The striatum was parcellated into …

Linked Mri Signatures Of The Brain's Acute And Persistent Response To Concussion In Female Varsity Rugby Players, Kathryn Y. Manning, Alberto Llera, Gregory A. Dekaban, Robert Bartha, Christy Barreira, Arthur Brown, Lisa Fischer, Tatiana Jevremovic, Kevin Blackney, Timothy J. Doherty, Douglas D. Fraser, Jeff Holmes, Christian F. Beckmann, Ravi S. Menon

Brain and Mind Institute Researchers' Publications

Acute brain changes are expected after concussion, yet there is growing evidence of persistent abnormalities well beyond clinical recovery and clearance to return to play. Multiparametric MRI is a powerful approach to non-invasively study structure-function relationships in the brain, however it remains challenging to interpret the complex and heterogeneous cascade of brain changes that manifest after concussion. Emerging conjunctive, data-driven analysis approaches like linked independent component analysis can integrate structural and functional imaging data to produce linked components that describe the shared inter-subject variance across images. These linked components not only offer the potential of a more comprehensive understanding of …

Brain Activation Time-Locked To Sleep Spindles Associated With Human Cognitive Abilities, Zhuo Fang, Laura B. Ray, Adrian M. Owen, Stuart M. Fogel

Brain and Mind Institute Researchers' Publications

Simultaneous electroencephalography and functional magnetic resonance imaging (EEG-fMRI) studies have revealed brain activations time-locked to spindles. Yet, the functional significance of these spindle-related brain activations is not understood. EEG studies have shown that inter-individual differences in the electrophysiological characteristics of spindles (e.g., density, amplitude, duration) are highly correlated with "Reasoning" abilities (i.e., "fluid intelligence"; problem solving skills, the ability to employ logic, identify complex patterns), but not short-term memory (STM) or verbal abilities. Spindle-dependent reactivation of brain areas recruited during new learning suggests night-to-night variations reflect offline memory processing. However, the functional significance of stable, trait-like inter-individual differences in brain …

Alive Inside, Andrew Peterson, Adrian M. Owen, Jason Karlawish

Brain and Mind Institute Researchers' Publications

This article provides an ethical analysis of the U.S. practice guideline update on disorders of consciousness. Our analysis focuses on the guideline’s recommendations regarding the use of investigational neuroimaging methods to assess brain-injured patients. Complex and multifaceted ethical issues have emerged because these methods alter the clinical understanding of consciousness. We address issues of false hope, patient suffering, and cost. We argue that, in spite of these concerns, there is significant benefit to using neuroimaging to assess brain-injured patients in most cases.

The Neural Basis Of External Responsiveness In Prolonged Disorders Of Consciousness, Clara A. Stafford, Adrian M. Owen, Davinia Fernández-Espejo

Brain and Mind Institute Researchers' Publications

Objective: To investigate the structural integrity of fibre tracts underlying overt motor behaviour in PDOC. Methods: This cross-sectional study examined 15 PDOC patients and 22 healthy participants. Eight PDOC patients met the criteria for the vegetative state, 5 met the criteria for the minimally conscious state and 2 met the criteria for emerging from the minimally conscious state. We used fibre tractography to reconstruct the white matter fibres known to be involved in voluntary motor execution (i.e., those connecting thalamus with M1, M1 with cerebellum, and cerebellum with thalamus) and used fractional anisotropy (FA) as a measure of their integrity. …

2019-1 Trading Motives In Asset Markets, Zijian Wang

Department of Economics Research Reports

I study how trading motives in asset markets affect equilibrium outcomes and welfare. I focus on two types of trading motives – informational and allocational. I show that while a fully separating equilibrium is the unique equilibrium when trading motives are known, multiple equilibria exist when trading motives are unknown. Moreover, forcing traders to reveal their trading motives may harm welfare. I also use this model to study how an asset market may exit a fire sale equilibrium and how government programs may eliminate private information and improve agents’ welfare.
