How Exposure To Poverty Related Issues In The Classroom Affects Students’ Attitudes And Interactions With Their Social Environment, Rocco Placenti

Theses, Dissertations and Culminating Projects

Impoverishment and its presence are the saddest forms of brutality and have long been recognized in the United States (U.S.). The common attitude of Americans is to view impoverishment from individualistic characteristics in which it is believed that individuals will not want to work if aid is offered to them. People’s attitudes towards those in poverty play a part in policy and practice in the American government. Therefore, this study explored how and the magnitude with which students’ connections within their ecological systems and their attitudes shifted after the introduction to an undergraduate course on families in poverty. A qualitative …

Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly

Graduate Theses and Dissertations

Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Making Connections: Understanding How Social Interaction Patterns Influence Work-Related Outcomes For Individuals With Disabilities, Christine Marie Manno

Graduate Theses and Dissertations

In the United States, approximately eight million individuals with disabilities are active in the workforce (Erickson et al., 2008). These individuals seek employment that allows for full use of their education, experience, and abilities, and provides growth and development opportunities (Ali et al., 2011). Despite protective legislation and inclusive organizational policies, individuals with disabilities are at least twice as likely as individuals without disabilities to experience underemployment and reduced access to advancement opportunities (Schur et al., 2009). Evidence suggests that some of these issues may be related to social interaction patterns. It appears that individuals with disabilities have a strong …

Genetic Control Of Prickles And Plant Height In Blackberry, Carmen Johns

Graduate Theses and Dissertations

The fresh-market blackberry (Rubus L. subgenus Rubus Watson) industry has been expanding for the past two decades. Blackberry market growth can be attributed to many factors including expanded production regions, improved production systems, and release of superior cultivars. Blackberry breeding is a time- and labor-intensive process which would benefit from implementation of molecular markers for highly heritable, important traits. Next generation sequencing, a high-quality reference genome, and software capable of analyzing this complex genome were applied in a genome-wide association study (GWAS) to reveal maker-trait associations related to prickles and plant height variation in fresh-market blackberry. In 2020 and 2021, …

Physics and Astronomy Faculty Research

SN 2014C was originally classified as a Type Ib supernova, but at phase ϕ = 127 days, post-explosion strong Hα emission was observed. SN 2014C has since been observed in radio, infrared, optical and X-ray bands. Here we present new optical spectroscopic and photometric data spanning ϕ = 947–2494 days post-explosion. We address the evolution of the broadened Hα emission line, as well as broad [O iii] emission and other lines. We also conduct a parallel analysis of all publicly available multiwavelength data. From our spectra, we find a nearly constant Hα FWHM velocity width of ∼2000 …

Missing Samples Reconstruction Using An Efficient And Robust Instantaneous Frequency Estimation Algorithm, Sadiq Ali, Nabeel Ali Khan

Turkish Journal of Electrical Engineering and Computer Sciences

In order to recover missing samples in a nonstationary signal, this paper employs a time-signal analysis and filtering method. The instantaneous frequency of a multicomponent signal is first estimated by employing a robust and computationally efficient method. Then the time-frequency filtering is performed using a dechirping operation to recover missing samples. These steps are repeated until convergence. The proposed method achieves better performance than the state of art methods both in terms of the accuracy of the recovered signal and computational efficiency.

Estimation Of Mode Shape In Power Systems Under Ambient Conditions Using Advanced Signal Processing Approach, Rahul S, Sunitha R

Turkish Journal of Electrical Engineering and Computer Sciences

This paper presents a dynamic approach for the monitoring and estimation of electromechanical oscillatory modes in the power system in real time with less computational burden. Extensive implementation of phasor measurement units (PMU) and the utilization of advanced signal processing techniques help in identifying the dynamic behaviors of oscillatory modes. Conventional nonstationary analysis techniques are computationally weak to handle a larger quantity of data in real-time. This research utilizes the variational mode decomposition (VMD) for signal decomposition, which is highly tolerant to noise and computationally more robust. The predefined parameters of the VMD process are assigned using FFT analysis of …

In particular, individual energy prosumers (someone that both produces and consumes energy) head toward smart home energy management systems (SHEMS) that include renewable energy sources in their homes. By integrating PV solar panels into houses, there is a need to optimize home energy production/consumption scenarios …

Assessing Manganese Concentrations In Groundwater Across The Shenandoah Valley, Va, Christopher Goldmann

Earth and Environmental Geosciences Student Honors Theses

Aqueous manganese (Mn²⁺) in groundwater used for drinking water has adverse aesthetic effects at concentrations ≥ 50 ppb and adverse human health effects at concentrations ≥ 100 ppb. Mn²⁺ in groundwater may have anthropogenic (mines, pesticide, gasoline) or geogenic (rocks and minerals) sources. Private drinking water wells are vulnerable to Mn²⁺ contamination because their water quality is not routinely monitored. This study uses groundwater data from 1587 private wells in the Shenandoah Valley, VA to assess the spatial distribution of Mn²⁺ in groundwater and identify possible Mn²⁺ contamination mechanisms. Using geospatial and statistical analyses …

Redefining The Boundary Between Appropriation And Regulation, Jessica L. Asbridge

BYU Law Review

The U.S. Supreme Court distinguishes between appropriations and regulations of property rights when interpreting the Fifth Amendment’s Takings Clause. While appropriations of any kind require just compensation to survive constitutional scrutiny, whether non-appropriative laws regulating property rights require compensation is determined on an ad hoc basis, guided by concerns of fairness and justness. In Cedar Point Nursery v. Hassid, the Court reaffirmed its prior precedent establishing the physical takings doctrine, providing that an appropriation is any government action that results in a physical invasion of an owner’s real property and a taking of the owner’s right to exclude. The Court …

How To Do Things With Magic: Yeat's Incantatory Performatives, Zoe E. Grout

English Honors Theses

It is a generally accepted truth that W.B. Yeats viewed his poetry as a part of his magical practice. His occult involvements are well-documented--he was a known member of the Theosophists, as well as the Hermetic Order of the Golden Dawn. Yeats's written work also made this connection abundantly clear through essays, autobiographies, poems, and especially his metaphysical discourse, A Vision. However, Yeats scholars have done little more than accept this fact; that is, they have not analyzed how exactly Yeats viewed his poetry as incantation, or the possible mechanisms by which this relationship functions. Hence, I hope to fill …

A Manufactured Culture: A Look Into How U.S. Imperialism Coerced The Philippine Economy Into A Culture Of Migration, Gio Ramos

Comm-entary

In this research paper, I investigate the origins of labor brokerages in the Philippines. The Philippine economy heavily relies on remittance which is when temporary overseas Filipino workers and emigrants send money back to their families in Philippines. This money is then flushed back into the local economy and keeps it running. Throughout this essay, I find that United States imperialism is a root cause for early labor systems in the archipelago. I analyze historic books and other expert studies on this topic to come to a final conclusion that illuminates my primary research question. How has US imperialism coerced …
