The Self-Reference Effect On Memory Among 4- To 6-Year-Olds: The Role Of Active Encoding And Cognitive Abilities, Alicia Nicole Bartlett

Electronic Theses and Dissertations

The self-reference effect (SRE) is the enhanced memory for information encoded with reference to oneself relative to information encoded with reference to another non-intimate person or the linguistic properties of a word (Rogers et al., 1977). This effect is measured with an encoding task and a surprise recall and/or recognition task. An important distinction among encoding tasks is whether they involve active or passive engagement with the to-be-remembered information. Tasks with active engagement require the participant to identify the relation between the referent and target object and then to perform a mental (e.g., evaluate desirability of objects) or physical (e.g., …

Regulation Of Natural Killer Cell Responses By Myeloid-Derived Suppressor Cells In Mouse Mammary Tumors, Mary Ibrahim Sep 2023

Regulation Of Natural Killer Cell Responses By Myeloid-Derived Suppressor Cells In Mouse Mammary Tumors, Mary Ibrahim

Electronic Theses and Dissertations

Natural killer (NK) cells of the innate immune system play important roles in anti-cancer immunity. NK cell functions are regulated by inhibitory and activating receptors, which recognize specific ligands on the target cells. One example is the inhibitory NKR-P1B receptor which recognizes the ligand C-type lectin-related protein b (Clr-b). Work in our lab has shown NKR-P1B:Clr-b interactions are involved in mammary tumor immunosurveillance by NK cells. However, the cellular interactions and factors involved in modulating NK cell functions via this receptor:ligand system in the tumor microenvironment (TME) are not fully understood.

Body Dissatisfaction And Depression: Investigating The Moderating Roles Of Maladaptive Investment In Appearance And Rumination, Mallory Forward Sep 2023

Body Dissatisfaction And Depression: Investigating The Moderating Roles Of Maladaptive Investment In Appearance And Rumination, Mallory Forward

Electronic Theses and Dissertations

Body dissatisfaction has been shown to predict the onset of depression (Bornioli et al., 2020; Paxton et at, 2006; Ferreiro et al., 2014; Sharpe et al., 2018). However, those for whom body dissatisfaction may be especially likely to result in depression has received little attention. The goal of the current study is to test the moderating roles of rumination and maladaptive investment in appearance in the association between body dissatisfaction and depression. It is suggested that those who are more maladaptively invested in their appearance may experience body dissatisfaction as particularly distressing because they place a high degree of importance …

New Memristive Architecture For Digital Circuits Design, Farzad Mozafari Sep 2023

New Memristive Architecture For Digital Circuits Design, Farzad Mozafari

Electronic Theses and Dissertations

Before 1971, all the electronics were based on three basic circuit elements. Until a professor from UC Berkeley reasoned that another basic circuit element exists, which he called memristor; characterized by the relationship between the charge and the flux-linkage. A memristor is essentially a resistor with memory. The resistance of a memristor (Memristance) depends on the amount of current that is passing through the device. In 2008, a research group at HP Labs succeeded to build an actual physical memristor. HP's memristor was a nanometer scale titanium dioxide thin film, composed of two doped and undoped regions, sandwiched between two …

Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise Sep 2023

Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise

Electronic Theses and Dissertations

The behavioural immune system (BIS) is a coordinated set of cognitive, affective, and behavioural responses that minimize pathogen contact. Prior to the COVID-19 pandemic, the majority of research on the BIS was limited to situations of acute pathogen threat. These studies identified that personal predispositions and environmental stimuli interact and lead to cognitive changes, including perceptual enhancements and attentional biases, as well as sensations of disgust. The cognitive and affective changes that follow pathogen exposure motivate pathogen avoidance behaviours and reduce the risk of infection. The BIS is highly adaptive in the context of acute pathogen threat, but less is …

Measurement And Evaluation Of Deep Learning Based 3d Reconstruction, Md Kaisar Ahmed Sep 2023

Measurement And Evaluation Of Deep Learning Based 3d Reconstruction, Md Kaisar Ahmed

Electronic Theses and Dissertations

Performances of Deep Learning (DL) based methods for 3D reconstruction are becoming at par or better than classical computer vision techniques. Learning requires data with proper annotations. While images have a standardized representation, there is currently no widely accepted format for efficiently representing 3D output shapes. The challenge lies in finding a format that can handle the high-resolution geometry of any shape while also being memory and computationally efficient. Therefore, most advanced learning-based 3D reconstructions are restricted to a certain domain. In this work, we compare the performance of different output representations for 3D reconstruction in different contexts including objects …

Loneliness, Risk-Taking, And Attention Deficit Hyperactivity Disorder During The Covid-19 Pandemic, Rebecca Nurgitz Sep 2023

Loneliness, Risk-Taking, And Attention Deficit Hyperactivity Disorder During The Covid-19 Pandemic, Rebecca Nurgitz

Electronic Theses and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder, commonly associated with impulsivity, risk-taking, and greater reported loneliness. Risk-taking can manifest in various ways, including reduced regard for health-conscious practices. Recent research indicates that individuals with ADHD may be less likely to follow pandemic safety instruction. (e.g., not following social distancing recommendations). Given that individuals with ADHD tend to discount the value of delayed reward in favour of immediate gratification, it can be presumed that individuals with greater ADHD symptomology may be more likely to not follow social distancing guidelines in an attempt to relieve acute feelings of loneliness. The …

Emotion Profiles In Dialectical Behaviour Therapy: Early Observations Anticipate Treatment Outcome, Florencia Andrea Cristoffanini Sep 2023

Emotion Profiles In Dialectical Behaviour Therapy: Early Observations Anticipate Treatment Outcome, Florencia Andrea Cristoffanini

Electronic Theses and Dissertations

Borderline Personality Disorder (BPD) can have various clinical presentations and is also difficult to treat. Researchers have investigated whether subtypes of BPD could explain variability in clinical presentations and outcomes after treatment. Previous research has identified subtypes of BPD based on temperament, which explain some variation in symptoms and outcomes. However, subtypes have typically been created using extensive self-report or structured-interview data. Instead, creating identifiable emotion profiles based on observational data could have a wider range of clinical and research applications, while helping to explain heterogeneity in BPD presentations and outcomes. This thesis is designed to look at emotion profiles …
