Seismic Response Mitigation Of Base-Isolated Buildings, Mohammad Hamayoun Stanikzai, Said Elias, Rajesh Rupakhety

Civil & Environmental Engineering Faculty Publications

Earthquake response mitigation of a base-isolated (BI) building equipped with (i) a single tuned mass damper at the top of the building, (ii) multiple tuned mass dampers (MTMDs) at the top of the building, and (iii) MTMDs distributed on different floors of the building (d-MTMDs) is studied. The shear-type buildings are modeled by considering only one lateral degree of freedom (DOF) at the floor level. Numerical approach of Newmark's integration is adopted for solving the coupled, governing differential equations of motion of 5- and 10-story BI buildings with and without TMD schemes. A set of 40 earthquake ground motions, scaled …

Parameter Estimation Of A Seasonal Poisson Inar(1) Model With Different Monthly Means, Turaj Vazifedan, Homa Jalaeian Taghadomi, Xixi Wang, Mujde Erten-Unal

Civil & Environmental Engineering Faculty Publications

Analysing seasonality in count time series is an essential application of statistics to predict phenomena in different fields like economics, agriculture, healthcare, environment, and climatic change. However, the information in the existing literature is scarce regarding the performances of relevant statistical models. This study provides the Yule-Walker (Y-W), Conditional Least Squares (CLS), and Maximum Likelihood Estimation (MLE) for First-order Non-negative Integer-valued Autoregressive, INAR(1), process with Poisson innovations with different monthly means. The performance of Y-W, CLS, and MLE are assessed by the Monte Carlo simulation method. The performance of this model is compared with another seasonal INAR(1) model by reproducing …

Resident Perceptions Of Human–Beaver Conflict In A Rural Landscape In Alberta, Canada, Nicholas T. Yarmey, Glynnis A. Hood

Human–Wildlife Interactions

The North American beaver (Castor canadensis) plays a key ecological role in wetland systems, yet their activities can result in costly damage to human infrastructure. Although qualitative research on human perceptions of beavers is rare, studies on human–beaver conflict in the United States identified generally positive attitudes toward beavers and opposition to lethal management, yet in Alberta, Canada, 79% of municipalities that managed beavers reported using trapping and shooting to remove problem beavers. Given the important ecological contributions of beavers and their potential conflict with humans, qualitative research is needed to assess perspectives of stakeholders who directly experience …

Access To Algorithms, Hannah Bloch-Wehba

Fordham Law Review

Federal, state, and local governments increasingly depend on automated systems—often procured from the private sector—to make key decisions about civil rights and liberties. When individuals affected by these decisions seek access to information about the algorithmic methodologies that produced them, governments frequently assert that this information is proprietary and cannot be disclosed. Recognizing that opaque algorithmic governance poses a threat to civil rights and liberties, scholars have called for a renewed focus on transparency and accountability for automated decision-making. But scholars have neglected a critical avenue for promoting public accountability and transparency for automated decision-making: the law of access to …

Three Types Of Organizational Boundary Spanning: Predicting Csr Policy Extensiveness Among Global Consumer Products Companies, Alwyn Lim, Shawn Pope

Research Collection School of Social Sciences

As part of the rise of a worldwide corporate social responsibility (CSR) movement, companies have increasingly incorporated social and environmental concerns into their policies. This paper examines the extensiveness of these policies, proposing that an underappreciated contributor is the degree of organizational boundary spanning. The paper is novel in integrating multiple types of boundary spanning into a single empirical framework, including product, sub‐unit, and national boundary spanning. The paper adds complexity to the literature by theorizing that different types of boundary spanning associate with CSR policy extensiveness in different issue areas. The results show that product spanning associates with CSR …

Numerical Analysis Of Carbon Nanotube-Based Nanofluid Unsteady Flow Amid Two Rotating Disks With Hall Current Coatings And Homogeneous-Heterogeneous Reactions, Muhammad Ramzan, Saima Riasat, Seifedine Kadry, Pin Kuntha, Yunyoung Nam, Fares Howari

All Works

© 2020 by the authors. In the present exploration, our objective is to investigate the importance of Hall current coatings in the establishment of Cattaneo-Christov (CC) heat flux model in an unsteady aqueous-based nanofluid flow comprising single (SWCNTs) and multi-walled (MWCNTs) carbon nanotubes (CNTs) amid two parallel rotating stretchable disks. The novelty of the presented model is strengthened with the presence of homogeneous-heterogeneous (HH) reactions and thermal stratification effects. The numerical solution of the system of coupled differential equations with high nonlinearity is obtained by applying the bvp4c function of MATLAB software. To corroborate the authenticity of the present envisioned …

Bacterial Community Dissimilarity In Soils Is Driven By Long-Termland-Use Practices, Aditi Sengupta, Janani Hariharan, Parwinder Grewal, Warren A. Dick

School of Earth, Environmental, & Marine Sciences Faculty Publications

Land‐use practices impact soil microbial functionality and biodiversity, with reports suggesting that anthropogenic activities potentially result in reduced microbial functions and loss of species. The objective of this study was to assess the effect of long‐term (>50 yr) land use (natural forest and grassland, and agricultural land) on soil bacterial community structure. A high‐throughput sequencing‐by‐synthesis approach of the 16S rRNA gene was used to study bacterial community and predicted functional profiles of Alfisols, as affected by variables including land‐use (forest, grass, agricultural) and soil/crop management (rotation and tillage) in long‐term experimental plots in Hoytville, OH. The distribution of the …

Architectonica Karsteni Rutsch, 1934 (Gastropoda: Architectonicidae) In Seamounts Of The Nazca-Desventuradas Marine Park: First Evidence Of An Extant Population In Chilean Waters Since The Miocene, Cynthia M. Asorey, Javier Sellanes, Erin E. Easton, Rüdiger Bieler, Ariadna Mecho

School of Earth, Environmental, & Marine Sciences Faculty Publications

The presence of Architectonicidae in Chile was previously recorded only from fossil material of eight species present during the Lower Miocene, when Architectonica karsteni had a geographic range that extended from Costa Rica to central Chile (34°S). No evidence of the presence of the family in Chile after the Lower Miocene have been reported. As part of this study, we report the discovery of A. karsteni at four seamountsat ~200 m water depth in the recently created Nazca-Desventuradas Marine Park, located ~900 km west of continental Chile. Morphological identification was based on protoconch diameter, coloration patterns, and teleoconch sculpture. We …

Non-Destructive, Rapid Differentiation Of Cell Types Relevant To Sexual Assault Investigations Utilizing Morphological And Autofluorescence Signatures, Taylor R. Moldenhauer

Master of Science in Forensic Science Directed Research Projects

Current methods for confirming the presence of spermatozoa in sexual assault samples can be time-consuming and often lack sensitivity; however, this remains the most definitive test for the presence of semen. Additionally, male DNA can be deposited without the presence of intact sperm as may be the case with seminal fluid from vasectomized individuals or sexual activity where seminal fluid is not recovered (e.g., perpetrator wears a condom, penetration without ejaculation, etc.). The ability to detect bodily fluids, as well as quantify their presence in a sample, could aid in forensic DNA analysis by limiting the amount of time performing …

The New "Essential": Rethinking Social Goods In The Age Of Covid-19, Olatunde C.A. Johnson

Faculty Scholarship

The Covid-19 crisis has laid bare the fragility of social insurance systems in the United States and the lack of income security and basic benefits for many workers and residents. The United States has long had weaker protections for workers compared to other liberal democracies racial and economic disparities among those most affected by these dislocations (analyses are hampered by a paucity of demographic data). Those who were socially and economically vulnerable before the pandemic (for example due to homelessness, immigration status, or incarceration) are likely to suffer the most harm. Changes in workplace conditions as a result of the …

Linked Fate: Justice And The Criminal Legal System During The Covid-19 Pandemic, Susan P. Sturm, Faiz Pirani, Hyun Kim, Natalie Behr, Zachary D. Hardwick

Faculty Scholarship

The concept of “linked fate” has taken on new meaning in the face of the COVID-19 pandemic. People all over the world – from every walk of life, spanning class, race, gender, and nationality – face a potentially deadly threat requiring cooperation and sacrifice. The plight of the most vulnerable among us affects the capacity of the larger community to cope with, recover, and learn from COVID-19’s devastating impact. COVID-19 makes visible and urgent the need to embrace our linked fate, “develop a sense of commonality and shared circumstances,” and unstick dysfunctional and inequitable political and legal systems.

© 2013 IEEE. Alzheimer's disease (AD) is a neurodegenerative condition that affects the central nervous system and represents 60% to 70% of all dementia cases. Due to an increased aging population, the number of patients diagnosed with AD is expected to exceed 131 million worldwide by 2050. The disease is characterized by various clinical symptoms and pathological features that define three main sequential decline stages, namely, early/mild, intermediate/moderate and late/severe stages. Although it is considered irreversible, early diagnosis of AD is highly desirable to help preserve cognitive function. However, early diagnosis is difficult due to different factors, including the patient-specific …

The Effect Of Dyad Rounding On Collaboration And Patient Experience, Amy Christensen, Korby Miller, Jason Neff, Rusty A. Moore, Sharee Hirschi, Katreena Collette Merrill

Faculty Publications

Communication among the healthcare team is essential to providing high-quality patient care. In the hospital, nurses care for multiple patients during their shift. Physicians or advanced practice clinicians (APCs) visit hospitalized patients daily to update orders, complete assessments, and contribute to care plans. One method to ensure that healthcare providers communicate effectively is interdisciplinary, or dyad, rounding in the hospital. This consists of purposeful rounding on each patient by the nurse and the physician or APC together to review the patient's status and update the care plan. When healthcare providers and nurses round together, it improves communication, patients are more …

Validation Of Ninein As An Ethanol-Related Quantitative Trait Gene: Reassessment, Design, And Functional Validation Of Reference Genes For Qpcr Analysis Of Brain Tissue In Mice, Jessica L. Jurmain

Theses and Dissertations

The increasing use of quantitative real-time polymerase chain reaction (qPCR) as a method for quantifying gene expression has led to an increased demand for standardization of data analysis methods to ensure accurate reporting and robust, reproducible results. The exponential nature of qPCR amplification results in the potential magnification of what are usually very small sources of error. Relative gene expression calculations circumvent this issue by normalizing target gene expression data to within-sample expression of a previously validated, stably expressed reference gene or genes. Multiple studies discussed herein have found that qPCR data are more reliable and reproducible when multiple reference …

Spit In My Mouth: Queer Intimacies, Material Intra-Actions, And Sensuous Becoming, Gm Keaton

Theses and Dissertations

This document describes my multidisciplinary art practice as it intersects with New Materialism, Queer and Affect theory, Ecology, and my embodied and experiential knowledge as a queer subject. The writing is divided into two categories. One is more theoretical, thinking through these different discourses. The other realizes them through relationships and intra-actions between my material kin and me. With these two modes of writing,I propose that embodied and felt knowing is as valid and illuminating as more traditional forms of knowledge. These sections are interdependent and resist linear logic, offering relational meanings to each reader as they find their way …

Prey Begins With Play, Seren C. Moran

Theses and Dissertations

My work examines the lasting psychological and emotional torment of trauma focusing on sexual violence against women. My thesis consists of five short animated films recounting non-fiction experiences of sexual assault. To contextualize my work within cultural and historical representations of sexual violence, this text reflects my research on the mishandling of rape in Western art history as well as contemporary politics and cinema. In both my work and research, I address the complicated, and often contradictory, internal reality of experiencing and remembering trauma and how this relates to artistic strategies such as collage and maximalism. My personal struggles recovering …

In Vivo Effects Of The Cb1 Allosteric Modulator Ldk1258, A Structural Analog Of Org-27569, Mohammed A. Mustafa

Theses and Dissertations

CB1 receptor allosteric modulators are an area of growing interest for their potential novel therapeutic actions. In the present study, we examined LDK1258 in a series of pharmacological in vivo tests sensitive to CB1 receptor stimulation. In the tetrad assay, LDK1258 produced significant decreases in locomotor activity and body temperature measures but did not produce either antinociception as measured in the tail-withdrawal assay or catalepsy as assessed in the bar test. These same effects were observed in both CB1 (-/-) and (+/+) mice. Moreover, LDK1258 failed to shift the dose-response curves of two orthosteric CB1 receptor agonists in the triad …

Exploring Whether Contextual Factors Relate To The Hoped-For And Feared Possible Selves Of Latinx Youth, Stephanie M. Romo

Theses and Dissertations

Youth’s hopes and fears for their future (i.e., hoped-for and feared possible selves) are related to their academic and health behavior outcomes. Much of the literature on possible selves focuses on African-American and European-American youth. In a sample of 132 Latinx youth, the present cross-sectional study utilized widely-used measures (i.e., Possible Selves Questionnaire, Beliefs about Education, Youth Risk Surveillance Survey) to identify the content and characteristics (e.g., strategies, balance) of their possible selves; investigate the relationship between contextual factors (e.g., sex, immigrant status) and possible selves; and, explore whether possible selves predicted youth’s beliefs about education and sexual risk behaviors. …

Structural Features Contributing To Methylenedioxypyrovalerone (Mdpv) Analog Inhibition Of The Human Dopamine Transporter, Zachary R. Spires

Theses and Dissertations

Monoamine transporters (MATs) are transmembrane neurotransmitter sodium symporters consisting of the dopamine, norepinephrine, and serotonin transporters: DAT, NET, and SERT, respectively. Following an action potential and neurotransmitter vesicular release, MAT-mediated reuptake of these neurotransmitters in the presynaptic membrane contributes to the termination of monoaminergic neurotransmission. MATs are the targets of many drugs providing therapeutic benefits or taken recreationally. One of these drugs is methylenedioxypyrovalerone (MDPV), an abused synthetic cathinone that is a high potency uptake inhibitor of the human DAT (hDAT). In contrast, MDPV is a low potency uptake inhibitor of the Drosophila melanogaster dopamine transporter (dDAT). The reasons for …

Against The Eyes Of God And Man: The Suicide And Alcohol Intoxication Deaths Of Enslaved People In Alexandria And Henrico County, Virginia, 1805-1829, Peighton L. Young

Theses and Dissertations

The purpose of this thesis is to provide a compressive examination of suicide and self-destructive behaviors within specific enslaved populations in early republic Virginia localities. I use coroners’ inquests as the primary means for identifying notable causes of death and potential behavioral patterns amongst the enslaved people presented in this study. I focused my investigation on two causes of death, demographics, and localities respectively: the drowning suicides committed by enslaved women along the Potomac River waterfront in Alexandria between 1807 and 1824 and the alcohol intoxication-related deaths of enslaved men in Henrico County between 1805 and 1829. Stepping away from …

Port To World, Samuel M. Brown

Theses and Dissertations

Among those that are ill for long periods, there is often a mistrust created not only in one’s own body but in the institution that promises a cure to the malady. Often this stems naturally from the dogma of the institution paired with one’s desire for wellness, for the institution's goals are many besides the overall health of the patient. Even when a patient is cured of an ailment, this is often just the first step in the actual healing process. The body can quickly change, and the mind takes time to catch up with the body's condition. My work …

Legal Permanent Residents In The Us Labor Market: Occupational Mobility Of High-Skilled And Low-Skilled Immigrants, Larissa Ferreira Coelho

Theses and Dissertations

Despite the vast research concerning immigrants and occupational mobility, little is known if the patterns for high-skilled and low-skilled workers differ. In this project, I analyze the pre-to-post migration occupational mobility of legal permanent residents in the US by using occupation and migration histories from the New Immigrant Survey. I contrast the first occupation in the US to the last occupation abroad using descriptive statistics, hypothesis testing, and multinomial logistic regression models. Findings show different patterns of occupational mobility for low-skilled and high-skilled workers. High-skilled immigrants were less likely to experience downward occupational mobility than their low-skilled counterparts. The high-skilled …
