Analysis of the Interaction between Distance Relay Protection System and Grid-Connected Inverter-Based Resources

This paper discusses protection challenges posed by the integration of inverter-based resources (IBR), such as large solar farms, into transmission systems due to varying, nonstandard control strategies and fault responses. In particular, this paper investigate the effects of IBR interconnection on distance protection using memory voltage polarization (relay 21). A time-domain electromagnetic transient program (EMTP) is used to perform simulations for analysis. The photovoltaic (PV) park available in the EMTP library is used as the IBR model and is converted into a white-box model in accordance with the latest industry standard, IEEE 2800-2022. The simulations are also experimentally validated to ensure that the simulation models accurately represent the behavior of the protection system under real-world conditions and to verify if the traditional relay settings are sufficient to protect the transmission line due to the low short-circuit current from the IBRs

Caregiver Engagement in Their Child\u27s Mental Health Rehabilitation Services: Utilizing the Hoover-Dempsey and Sandler Model of Parental Involvement (2005) in Mental Health Counseling

Mental Health Rehabilitation (MHR) is a widely utilized community mental health service in Louisiana for low-income families. However, treatment adherence, including caregiver engagement for minor clients, is often low. There is still limited understanding of the barriers to caregiver engagement and few tools to assess these barriers and engagement behaviors. Clinicians, caregivers, and clients currently engaged in MHR services completed a modified version of the Parent Involvement Project Questionnaire (PIPQ) to determine if this scale and its associated theory, the Hoover-Dempsey and Sandler Model of Parental Involvement (2005), can be used in a mental health counseling format to assess for caregiver engagement in counseling. Reliability scores using Cronbach\u27s alpha were examined to determine whether the PIPQ maintains similar reliability values to the original survey. Independent T-tests were also conducted to examine differences in clinician ratings from the caregivers and clients. Hierarchical and simple regression analyses were run to determine how caregiver beliefs and perceptions impact their involvement behaviors and their child\u27s perceptions of these behaviors. Patterns emerged in the data that indicated that the modified PIPQ was a reliable measure of caregiver engagement and that clinicians often rated caregivers and clients higher on this measure than they rated themselves. Several caregiver beliefs and perceptions about their engagement also showed interactions with their forms of engagement behaviors and their child’s perception of these behaviors. Responses to calls for participants also indicated barriers to MHR and other community agencies participating in research studies that warrant future study

Choreographing the Rhythms of Observation: Dynamics for Ranged Observer Bipartite-Unipartite SpatioTemporal (ROBUST) Networks

Existing network analysis methods struggle to optimize observer placements in dynamic environments with limited visibility. This dissertation introduces the novel ROBUST (Ranged Observer Bipartite-Unipartite SpatioTemporal) framework, offering a significant advancement in modeling, analyzing, and optimizing observer networks within complex spatiotemporal domains. ROBUST leverages a unique bipartite-unipartite approach, distinguishing between observer and observable entities while incorporating spatial constraints and temporal dynamics. This research extends spatiotemporal network theory by introducing novel graph-based measures, including myopic degree, spatial closeness centrality, and edge length proportion. These measures, coupled with advanced clustering techniques like Proximal Recurrence, provide insights into network structure, resilience, and the effectiveness of observer placements. The ROBUST framework demonstrates superior resource allocation and strategic responsiveness compared to conventional models. Case studies in oceanographic monitoring, urban safety networks, and multi-agent path planning showcases its practical applicability and adaptability. Results demonstrate significant improvements in coverage, response times, and overall network efficiency. This work paves the way for future research in incorporating imperfect knowledge, refining temporal pathing methodologies, and expanding the scope of applications. By bridging theoretical advancements with practical solutions, ROBUST stands as a significant contribution to the field, promising to inform and inspire ongoing and future endeavors in network optimization and multi-agent system planning

Banat al-Nahda: Mary Ajami and Nazik al-‘Abed’s Creation of Women’s Spaces in Greater Syria 1910-1920

This thesis examines the spaces created by the pioneers of the Syrian women’s movement in 1910-1920, Mary Ajami and Nazik al-‘Abed, using spatial analysis and analyzing the discursive space they created in their magazines. Throughout the brief independence during Prince Faysal’s rule in 1918-1920, Ajami and al-‘Abed mobilized to allow women to enter male-dominated spaces and discourses. They utilized their pioneering magazines, al-Arus and Nur al-Fayha,’ to reach women in public and private spaces. The Women’s Literary Forum was established to foster women’s self-representation and education. At the same time, the School for the Daughters of the Martyrs and Nur al-Fayha’ Society aimed to create an uncontested presence for women in national affairs. This paper aims to show that Ajami and al-‘Abed adopted a creative framework to help women gain their rights by linking the idea of women’s liberation with Syria’s independence

Financial Risk in a Changing Climate

Essay 1: Given the missing-not-at-random (MNAR) nature of carbon emissions figures under the voluntary disclosure regulator environment, this research imputes synthetic emissions figures for both disclosing and non-disclosing publicly traded US firms, using an IV approach adapted for sample bias correction. The forward-observing implied cost of equity capital measure is consistently higher for carbon-intensive firms regardless of disclosure decision. This higher cost found in the large swath of high-emitting firms reduces the net present value of green transition investments, thus fueling existing research on the counterproductive natures of capital allocation in efforts to reduce corporate pollution. Contrary to emerging research, the paper attributes the cause to a climate-change risk factor due to high-elasticity constraints, rather than the sole impact of sustainable investing. Essay 2: This research explores the risk transmission impacts of China’s carbon emissions, green energy indices, and traditional energy and commodity indices. Supplement analysis observes impacts within China’s major firms as well as the regulative differences in its Emission Trading Systems when compared to those in developed economies. Utilizing the Vector Autoregressive (VAR) model and an innovative quantile connectedness framework, the research uncovers a substantial degree of cross-market risk transmission during the ongoing recession in China, exceeding 80%. The increased volatility coincides with the volatility in oil and energy and attributed from the shocks from global supply chain disruptions, Russian-Ukrainian conflict, and post pandemic recovery
