Jet-Driven Mixing Regimes Identified In The Unsteady Isothermal Filling Of Rectangular Municipal Water Storage Tanks, Pramod Narayan Bangalore, K. (Kelly) O. Homan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Poor mixing of old and new water in municipal water storage vessels is a well-documented basis for potentially harmful water quality degradation in drinking water distribution systems. This numerical study investigates the effects of inflow and operational variables on mixing in the jet-driven filling process, with a particular focus on the transition from inadequate to sufficient mixing levels. An isothermal unsteady reynolds-averaged-navier-stokes volume-of-fluid (RANS-VOF) simulation is used to model the variable-volume filling process, accounting for the moving free surface following a draw-down in the stored water volume. A low diffusivity tracer is used to mark the old-water volume, and a …

Mask2former With Improved Query For Semantic Segmentation In Remote-Sensing Images, Shichen Guo, Qi Wang, Shiming Xiang, Shuwen Wang, Xuezhi Wang

Computer Science Faculty Publications and Presentations

Semantic segmentation of remote sensing (RS) images is vital in various practical applications, including urban construction planning, natural disaster monitoring, and land resources investigation. However, RS images are captured by airplanes or satellites at high altitudes and long distances, resulting in ground objects of the same category being scattered in various corners of the image. Moreover, objects of different sizes appear simultaneously in RS images. For example, some objects occupy a large area in urban scenes, while others only have small regions. Technically, the above two universal situations pose significant challenges to the segmentation with a high quality for RS …

Investigating Communication Of Findings In Environmental Impact Assessment And Developing A Research Agenda For Improvement, Alan Bond, Francois Retief, Angus Morrison-Saunders, Jenny Pope, Reece C. Alberts, Claudine Roos, Dirk Cilliers

Research outputs 2022 to 2026

Environmental Impact Assessment (EIA) aims to embed consideration of the significance of predicted environmental consequences (the findings) of proposed developments into approval decision making. Achieving this aim relies on adequate communication of the findings of the EIA to the stakeholders, especially the decision makers responsible for the approval decision. However, the naïve assumption that this communication of findings can be effectively achieved through the publication of a written report pervades legislation worldwide, despite decades of evidence to the contrary. As a first step towards improving such communication, this research identifies the contingent conditions associated with effectively transferring EIA findings from …

Psychological Science Faculty Publications and Presentations

Increased stress among parents of youth with ASD has been well-documented. However, research on aspects of the parent-child relationship and subsequent links to parenting stress is limited. We assessed parents (N = 511) of youth with ASD to examine relations between parenting stress and parent-child quality time (amount of quality time, shared enjoyment, synchronicity). Elevated parenting stress was associated with less time spent engaging with youth in shared activities and decreased parent and child enjoyment during shared interactions. Parents with elevated stress reported engaging in shared activities and experiencing synchronicity with their child less often than parents below the …

Effectiveness Of Concurrent Ankle Arthroscopy During Open Reduction And Internal Fixation Of Malleolar Fractures In Prevention Of Common Short-Term Complications, Naohiro Shibuya, Daniel C. Jupiter

School of Podiatric Medicine Publications

Rotational malleolar fractures result in a high prevalence of intra-articular pathologies; therefore, routine arthroscopic assessment may be beneficial in the surgical treatment of ankle fractures. However, the clinical studies regarding the effectiveness of arthroscopy thus far have mixed results. We investigated the efficacy of concurrent arthroscopy during the treatment of malleolar fractures using a large U.S. healthcare data set. Those who had arthroscopy were compared with those who did not, during the surgical treatment of malleolar fractures, while adjusting for covariates of clinical relevance. The analysis showed that concurrent arthroscopy is protective against postoperative repeat surgery (OR = 0.13, 95CI …

Scientists Explain The Underrepresentation Of Women In Physics Compared To Biology In Four National Contexts, Esther Chan, Di Di, Elaine Howard Ecklund

Sociology

Women are consistently underrepresented in physics when compared to biology. Yet how scientists themselves explain the causes of this underrepresentation is understudied outside the US context. In this research, we ask the following question: How do scientists in different national/regional contexts explain why there are fewer women in physics than biology? Using original survey data collected among academic biologists and physicists in the US (N = 1777), Italy (N = 1257), France (N = 648), and Taiwan (N = 780), we examine how scientists' social identities, social locations, and country context shape essentialist, individualist, and structural …

Threading A Decolonial Feminist Response To Covid-19: One Community Psychologist's Reflection On The Assemblages Of Violence, Jesica S. Fernandez

Ethnic Studies

To challenge and interrogate the assemblages of violence produced by racial capitalism, and exacerbated by the COVID-19 pandemic, community psychologists must engage in a transdisciplinary critical ethically reflexive practice. In this reflexive essay, or first-person account, I offer a decolonial feminist response to COVID-19 that draws strength from the writings of three women of Color decolonial and postcolonial feminist thinkers: Gloria E. Anzaldúa, Sylvia Wynter, and Arundhati Roy. Through their writings I share my reflections on the sociopolitical moment associated with COVID-19. Of importance, I argue in support of engaging a decolonial feminist standpoint to understand the inequitable and dehumanizing …

An Argument For The Integration Of Black Psychology In Undergraduate Psychology Program, Kelsey D. Glass

University Honors Theses

When we think about the theories behind the foundation of American psychology, many European names come to mind (i.e. Freud, Erickson, Brofenbrenner etc.). This Euro-American mode of psychology has been the standard in American Undergraduate education since the founding of a formal psychological education in the U.S. but what about names like Wade Nobles, Joseph White, Na-im Akbar, or Linda James Myers? These forerunners of Black Psychology are elusive in the foundational education of current American Undergraduate programs due to longstanding racial bias in the field. This bias reflects the systemic racism that American culture was founded on. This paper …

A Novel Data Fusion Fr Amework To Enhance Contextual Awareness Of The Autonomous Vehicles For Accurate Decision Making, Henry Alexander Ignatious

Dissertations

Autonomous driving has the potential to bring significant changes and benefits to various aspects of transportation. Autonomous vehicles (AVs) use a combination of advanced sensors, cameras, radar, lidar, GPS, maps, and AI algorithms to perceive their environment, make decisions, and control their movements. Though there is a significant increase in the AVs utility, there are several challenges associated with the AVs among which ensuring safety and security for a reliable drive is still an existing challenge. The majority of accidents involving the AVs result from faulty decision-making resulting in fatal incidents. Multiple elements contribute to the flawed decision-making in autonomous …

Ecotheology In Context: A Critical Phenomenological Study Of Graduates Of Environmentally Focused Seminary Programs In The United States Of America, Cherice Bock

Antioch University Dissertations & Theses

In recent decades, the field of ecotheology has emerged in dialogue with the context of the interconnected environmental and climate crises, particularly relating to the critique of Christianity being used to justify human and resource exploitation. A range of disciplines within the religious academy have taken up these intersecting concerns, together termed “ecologically informed theological education.” Graduate institutions training faith leaders and theological educators have created degree programs and certifications, and/or incorporated awareness of ecology, sustainability, and care for creation into their curricula. A research approach for ecotheology is described through the conceptual framework of critical ecotheology, which acknowledges ecotheology …

Can Steam Be Usable As A "Plus" For Ventilation Shutdown?, A. V. Mendoza, S. Weimer, Z. Williams

Poultry Science Faculty Publications and Presentations

The American Veterinary Medical Association (AVMA), preferred depopulation methods (i.e., foam, containerized gassing, and mechanical methods) can be challenging when depopulating cage and aviary commercial laying hen houses for multiple reasons. When preferred methods are not feasible or resources are unavailable, ventilation shutdown plus (VSD+) heat and/or carbon dioxide (CO₂) is approved for emergency situations. Both recognized “pluses” work but can have issues as VSD+ heat typically causes a decrease in environmental humidity and can affect PVC structures, while CO₂ can be a human safety concern and has procurement problem during emergencies. …

BACKGROUND: This manuscript provides a summary of the current evidence to support the criteria for diagnosing a child or adult with hypophosphatasia (HPP). The diagnosis of HPP is made on the basis of integrating clinical features, laboratory profile, radiographic features of the condition, and DNA analysis identifying the presence of a pathogenic variant of the tissue nonspecific alkaline phosphatase gene (ALPL). Often, the diagnosis of HPP is significantly delayed in both adults and children, and updated diagnostic criteria are required to keep pace with our evolving understanding regarding the relationship between ALPL genotype and associated HPP clinical features.

METHODS: An …

Daniels, Susan Ellis Weismer, Cy Nadler, Karen Pazol, Nuri M. Reyes, Steven Rosenberg, Eric Rubenstein, Lisa D. Wiggins, Marshalyn Yeargin-Allsopp, Maureen S. Durkin

Manuscripts, Articles, Book Chapters and Other Papers

Intellectual disability (ID) commonly co-occurs in children with autism. Although diagnostic criteria for ID require impairments in both cognitive and adaptive functioning, most population-based estimates of the frequency of co-occurring ID in children with autism-including studies of racial and ethnic disparities in co-occurring autism and ID-base the definition of ID solely on cognitive scores. The goal of this analysis was to examine the effect of including both cognitive and adaptive behavior criteria on estimates of co-occurring ID in a well-characterized sample of 2- to 5-year-old children with autism. Participants included 3264 children with research or community diagnoses of autism enrolled …
