Overcoming Foreign Language Anxiety In An Emotionally Intelligent Tutoring System, Daneih Ismail

College of Computing and Digital Media Dissertations

Learning a foreign language entails cognitive and emotional obstacles. It involves complicated mental processes that affect learning and emotions. Positive emotions such as motivation, encouragement, and satisfaction increase learning achievement, while negative emotions like anxiety, frustration, and confusion may reduce performance. Foreign Language Anxiety (FLA) is a specific type of anxiety accompanying learning a foreign language. It is considered a main impediment that hinders learning, reduces achievements, and diminishes interest in learning.

Detecting FLA is the first step toward reducing and eventually overcoming it. Previously, researchers have been detecting FLA using physical measurements and self-reports. Using physical measures is direct …

Teacher, Gatekeeper, Or Team Member: Supervisor Positioning In Programmatic Assessment, Janica Jamieson, Simone Gibson, Margaret Hay, Claire Palermo

Research outputs 2022 to 2026

Competency-based assessment is undergoing an evolution with the popularisation of programmatic assessment. Fundamental to programmatic assessment are the attributes and buy-in of the people participating in the system. Our previous research revealed unspoken, yet influential, cultural and relationship dynamics that interact with programmatic assessment to influence success. Pulling at this thread, we conducted secondary analysis of focus groups and interviews (n = 44 supervisors) using the critical lens of Positioning Theory to explore how workplace supervisors experienced and perceived their positioning within programmatic assessment. We found that supervisors positioned themselves in two of three ways. First, supervisors universally positioned themselves …

Exploring The Impact Of Signal Quality Enhancement On Heart Sound Classification Models, Davoud Shariat Panah, Andrew Hines, Susan Mckeever

Articles

Limited cardiology resources increase the urgency for automated heart disease screening for the general public. Heart sound diagnostic models have been recently employed as a cost-effective solution for the initial screening of heart disease. Noise in heart sound recordings, however, can reduce the performance of such data-driven models. Various quality enhancement approaches have been adopted to alleviate the destructive impact of noise on model performance. One approach is universal noise reduction which applies denoising techniques to recordings, irrespective of their noise level. The second approach is targeted noise reduction, which applies denoising solely to recordings deemed to need it, based …

Challenging skeletal repairs are frequently seen in patients experiencing systemic inflammation. To tackle the complexity and heterogeneity of the skeletal repair process, we performed single-cell RNA sequencing and revealed that progenitor cells were one of the major lineages responsive to elevated inflammation and this response adversely affected progenitor differentiation by upregulation of Rbpjk in fracture nonunion. We then validated the interplay between inflammation (via constitutive activation of Ikk2, Ikk2ca) and Rbpjk specifically in progenitors by using genetic animal models. Focusing on epigenetic regulation, we identified Rbpjk as a direct target of Dnmt3b. Mechanistically, inflammation decreased Dnmt3b expression in progenitor cells, …

Worldwide, over 800 million people are affected by kidney disease, yet its pathogenesis remains elusive, hindering the development of novel therapeutics. In this study, we used kidney-specific expression of quantitative traits and single-nucleus open chromatin analysis to show that genetic variants linked to kidney dysfunction on chromosome 20 target the acyl-CoA synthetase short-chain family 2 (ACSS2). By generating ACSS2-KO mice, we demonstrated their protection from kidney fibrosis in multiple disease models. Our analysis of primary tubular cells revealed that ACSS2 regulated de novo lipogenesis (DNL), causing NADPH depletion and increasing ROS levels, ultimately leading to NLRP3-dependent pyroptosis. Additionally, we discovered …

Tiny Drifters Amidst Global Change: Examining Environmental Drivers, Trophic Impacts, And Management Strategies Of Estuarine Plankton Communities In The Anthropocene, Taylor Nicole Dodrill

Dissertations and Theses

Plankton productivity supports estuarine food webs, and has been tied to the success of fisheries, macroinvertebrates, and cultured shellfish yields. Climate change and alterations to nutrient loads are thought to be influencing plankton assemblages, with toxin-producing harmful algal blooms (HABs) on the rise and nutritional quality of plankton declining globally. These shifts in plankton communities may contribute to low biomass yields and toxin-based closures of important fisheries. The objectives of this dissertation are to identify environmental drivers, trophic impacts, and management strategies to understand and respond to changing estuarine plankton communities. To address these objectives, I used a combination of …

Development And Validation Of Ethical Blindness Scale, Darija Aleksić, Guido Palazzo

Economic and Business Review

Recent models of ethical decision making have underlined the influence of unconscious processes of unethical behavior, and ethical blindness has been identified as a construct that deepens the understanding of unintentional unethical behavior. However, to date, no empirically tested measure of ethical blindness exists. Consequently, we have explored and developed a tool for measuring ethical blindness, which is presented in this paper. Based on qualitative data from interviews with individuals employed in different industries and a literature review, we developed a multidimensional measure of ethical blindness. The measure was tested and validated in several consecutive steps on three quantitative data …

The purpose of this study was to evaluate the effectiveness of traditional and active lecture methods in higher-education courses. A multiple group convergent parallel mixed method design was used, with measurement of learning, attention, and student preference for active or traditional lecture methods. Six faculty at a public university in the northeast region of the United States engaged 178 undergraduate and graduate students in a traditional lecture session and an active lecture session during the Spring 2022 semester. Results indicated effectiveness of active and traditional lecture approaches (p < .05). Analysis of qualitative and quantitative data in the study provides additional information regarding student preference for active lecture based on perceptions of increased learning benefits, interaction/engagement, attention, activities, discussion, and the use of multimedia. In implementing both traditional and active lecture sessions this study employed pre-lecture and post-lecture quizzes that students found to be very beneficial to learning.
