Biharmonic Functions On S^2 And H^2
No full textThe study herein aims to understand bi-harmonic functions on 2-dimensional sphere S² and hyperbolic space H² in relation with harmonic and bi-harmonic functions on Eu- clidean space R². For this purpose the properties of harmonic functions and the conceptual construc- tion of bi-harmonic functions from general functions using these properties are reviewed. The Poisson’s equations on R² are applied to construct and/or classify bi-harmonic functions on the warped product spaces as well as the conformally flat surfaces of S² and H² . The construction of bi-harmonic functions on R² by using analytic complex functions and some applications in elasticity are reviewed. We are able to describe all rotationally symmetric bi-harmonic functions on S² and H² using conformal models and polar coordinates in R². It is concluded from these studies that although the bi-harmonic functions on R² can be abundantly constructed from the arbitrary analytic complex functions, explicit solu- tions of bi-harmonic equations on 2-dimensional sphere S² and hyperbolic space H² could be a challenge due to the difficulty in solving the corresponding nonlinear Poisson’s equations
¿Hablas Español?: The Experiences of Recently Graduated Bilingual Counselors Providing Spanish Language Counseling Services to the Latinx/E Population
No full textThe purpose of this study was to understand the phenomena of bilingual counselors who work with the Latinx/e population and provide counseling services using the Spanish language. Specifically, this researcher hoped to highlight the voices of recently graduated bilingual counselors who graduated within the last 5 years from CACREP programs and were trained using the English language. Currently, there is limited research on the training and experiences of bilingual counselors, but current research indicates a need for specialized training for bilingual counselors. Furthermore, research on recently graduated counselors highlights certain developmental milestones that occur during this stage of a counselor’s career development that are relevant to understanding the impact of training. This study used a qualitative approach by using a phenomenological lens with a constructivist paradigm, as well as a thematic analysis to explore the research question: What are the experiences of recently graduated (i.e., within the last 5 years) bilingual counselors who work with the Latinx/e population using the Spanish language in their counseling sessions relative to their training (which is mainly in English)? From this, five themes emerged: (a) increased demand and complexities in roles, (b) impact of language proficiency on therapeutic efficacy, (c) cultural sensitivity and awareness, (d) motivation and commitment to serving the Hispanic/Latinx/e community, and (e) perceived lack of resources. The researcher closes with a discussion of the study’s implications, recommendations for practice and future research, and limitations that should guide interpretation of the study’s results
Digging Up the Past: Famines in Irish Gothic Literature Since the Early Nineteenth Century
No full textThe purpose of this study is to identify potential relationships between Ireland’s famines and Irish Gothic literature, to build upon past scholarship, and to identify what famine elements are unique to the Irish Gothic genre. This study will focus on how famines contribute to establishing an Irish Gothic genre that does not end with the nineteenth century but continues through the twentieth century. The recent scholarship I will be considering that addresses Irish literature and The Great Famine of 1845 include Christopher Morash’s 1995 book, Writing the Irish Famine; Melissa Fegan’s 2002 book, Literature and the Irish Famine 1845-1919; David Valone’s 2002 edited collection of essays, Ireland’s Great Hunger: Silence, Memory, and Commemoration; and Marguérite Corporaal’s 2017 book, Relocated Memories: The Great Famine in Irish and Diaspora Fiction, 1846-1870. The current scholarship does not address other famines or a combination of famines and what relation they have to the Irish Gothic genre. Scholarship specifically related to Irish Gothic that I will also consider include works by Luke Gibbons, Jarlath Killeen, David Punter, Jim Hansen, Christina Morin, Robert Smart, Jim Kelly, and Stephen Carleton. In this study I closely analyze how authors depict Irish famines in the following texts: Martin McDonagh’s A Skull in Connemara, Bram Stoker’s Dracula, and Charles Robert Maturin’s Melmoth the Wanderer. This study also utilizes Jacques Derrida’s concepts of “hauntology” and “visor effect” from his text Specters of Marx: The State of the Debt, the Work of Mourning and the New International, and concepts of Edmund Burke’s “Sublime” and George Berkeley’s “perception” to discuss how famines in Ireland continue to “haunt” Irish Gothic literature. Each chapter focuses on one Gothic text and addresses unique elements related to famine. By applying these concepts to the above-mentioned texts, this study seeks to understand relationships between famines and the Irish Gothic genre
Infidelity’s Impact on African American Women’s Identity: A Phenomenological Study
No full textInfidelity is a widespread issue that individuals may confront within a relationship, resulting in breaches of fidelity and loyalty. Over time, infidelity has adapted to the evolving social, cultural, and technological landscapes (Blow & Hartnett, 2005a; Campbell & Kohut, 2017; Hertlein & Webster, 2008; Vossler, 2016). This dissertation explored the lived experiences of African American women who have encountered infidelity within their intimate relationships, with a focus on the profound impact of infidelity on their sense of identity. Through qualitative inquiry, this research explored the emotional, psychological, and social dimensions of infidelity\u27s impact, including coping strategies, processes of self-reconstruction, and potential growth. The study examined how infidelity reshapes the self-perception, self-esteem, and overall identity of African American women. It recognized the significance of race, culture, and gender norms as intersecting identities, acknowledging the unique challenges and opportunities they present in the context of infidelity. This study utilized a phenomenological approach, as phenomenology allowed for a comprehensive exploration of the nuanced aspects of a participant\u27s experiences, emotions, and complex factors (Creswell & Poth, 2017). Similarly, it allowed for a deep understanding of the personal meaning and detailed descriptions of the lived experiences of African American women who have encountered infidelity, which in turn influences their worldview (Marshall & Rossman, 2006). The study used a purposive sampling strategy to identify participants through various mediums (e.g., social media, clinician referrals, etc.). Once participants self-identified for meeting study criteria, participants participated in a semi-structured interview to explore their personal experiences with infidelity, the factors associated with impacting their experience, and their coping skills. By amplifying the voices through the lived experiences of African American women, this research contributed to a more comprehensive understanding of the relationships between intimate relationship dynamics, infidelity, and identity development within this specific demographic. Ultimately, this dissertation informed therapeutic approaches and fostered inclusive conversations surrounding healing and growth in the wake of relationship betrayal, with a focus on the experiences of African American women
Role Of G1P3 In Inducing Mitochondrial Derived Vesicle and Its Link to Endomembrane Vesicle
No full textIn the United States, breast cancer is the second most prevalent type of cancer among women, with 6% of those women developing metastasis. Previously reported, G1P3/IFI6 is an interferon (IFN)-stimulated gene with an anti-apoptotic property that elevates mitochondrial reactive oxygen species (mtROS) and promotes metastasis of G1P3-overexpressed breast cancer cells (MCF7/G1P3). Based on this, we hypothesized that G1P3 mediates the lysosomal degradation of ROS damaged mitochondria as a form of quality control. To test this hypothesis, G1p3 was down regulated using siRNA specific to G1P3 in MCF7/G1P3 cells, investigating mitochondria membrane potential and co-occurrence of mitochondrial outer marker PDH and inner marker TOMM20 with lysosomal marker LAMP1. Additionally, MCF7/VECTOR and MCF7/G1P3 immuno-stained cells were treated with ROS scavenger Mito TEMPO, mitochondria electron transport chain complex III inhibitor Antimycin A and lysosomal acidification inhibitor Bafilomycin A1to inspect the co-occurrence of TOMM20 with LAMP1 and PDH with LAMP1. Lastly, isolated mitochondria from MCF7/VECTOR and MCF7/G1P3 iv cells were resuspended in energy regenerating buffer to investigate mitochondrial vesical formation. Downregulating G1P3 expression in MCF7/G1P3 cells lowered mitochondrial membrane potential. Whereas in immunostaining result, knockdown of G1P3 suggests that in G1P3 cells, mitochondria region devoid of TOMM20 co-occur with lysosome which includes mitochondria matrix PDH. Additionally, Mito TEMPO result suggests reduced level of mtROS promotes the co-occurrence of TOMM20 free region of mitochondria with lysosome in MCF7/G1P3 cells. While Antimycin A result suggests that higher mtROS level decreases co-occurrence of TOMM20 with LAMP1 in G1P3 expressing cells unaffecting matrix association. In the same way, Bafilomycin A1 treatment result has similar effect as Antimycin A. Lastly, neither MCF7/VECTOR or MCF7/G1P3 cell’s resuspended mitochondria formed vesicles when in energy regenerating buffer. In summary, G1P3 promotes the co-occurrence of Mitochondrial region free of TOMM20 with lysosomes and is regulated by mtROS. Understanding the molecular route of G1P3 controlling mitochondrial cargo with respect to lysosomes may result in new approaches to the treatment of breast cancer
Influence of Tillage on Aggregate Stability in Clay Soils of North Texas
No full textSoil management practices have drastic effects on soil overall health, particularly tillage. Tillage and cover crops can influence a multitude of soil physical properties. One measurable property is aggregate stability, which is commonly considered an indicator of soil quality, erosion potential, and water infiltration. Two studies were conducted at the Texas A&M University Greenville Research, Extension, and Teaching Farm to investigate the aggregate stability of clay soils. One study investigated soils under various tillage regimes (no-till, vertical till, and strip-till) implemented over four years. The second study evaluated soils under one year of cover crop (hayed, controlled with herbicide, or bare ground). Soil samples were collected from each study and processed according to methods developed by Yoder (1936) and modified by Kemper and Rosenau (1986) and Garcia et al. (2022) to determine the amount of stable aggregates and the distribution of aggregate by size (\u3c1 mm, 1-2 mm, and \u3e2 mm). No differences in aggregate stability were found among tillage or cover crop treatments. Differences were noted in 1-2 mm and \u3c1 mm aggregates for the May 2024 sampling in the tillage study. Bi-annual vertical tillage had the most 1-2 mm aggregates, and no-till and annual vertical tillage had the least. For \u3c1 mm aggregates, no-till, and annual vertical tillage had the most, and bi-annual vertical tillage had the least. While these differences in aggregate size suggest that tillage does have an influence on aggregate size, this effect did not translate to a difference in aggregate stability, which is directly related to soil health. The results of this study indicate that the influence of tillage and cover crops on aggregate stability and overall soil health is less pronounced in heavy clay soils than in other soils in well-studied, agronomically important regions
Lived Experiences of LGBTQIA+ Adults in Rural Texas Who Attempted to Utilize Affirming Mental Health Services
No full textCurrent literature speaks to individual elements discussed in this study (i.e. mental health, LGBTQIA+ status, Texas and/or rural mental health care, etc.) but a study that combines all of these identities and factors cannot be found. The purpose of the study was to meet that gap by exploring the lived experiences of adult individuals who self-identity as LGBTQIA+ living in rural Texas and have attempted to access affirming mental health services. The researcher aimed to do this by conducting a phenomenological, qualitative study highlighting LGBTQIA+ voices. Through semi-structured interviews, three themes were found from the data: Affirmative Therapy, Barriers to Care, and Potential Solutions. The researcher concludes this document discussing implications and ideas for future researc
Navigating Social Commerce: Analyzing the Economic Impact and Practical Strategies for Small E-commerce Ventures Utilizing Social Networks for Sales and Brand Loyalty
No full textAutoethnography For Professional Growth In Science and Social Studies Pedagogy
No full textA large body of research shows that reading and math instruction receive significantly more time, attention, and instructional minutes than science and social studies instruction in elementary classrooms(VanFossen, 2005; Wilkens, 2009; Blank, 2013; Rosenshine, 2015). In this study, I use an autoethnographic reflective research framework to combat the challenges of science and social studies professional growth while student teaching at a rural texas elementary school that has chosen to require only math and reading instruction from their teachers. It was found that science and social studies is most easily incorporated through the existing reading and math curriculum. The autoethnographic process promoted teacher growth by highlighting areas in need of improvement and giving a platform for the preservice teacher to brainstorm ideas. The study spanned instructional from January 2024 - March 2024 in a rural Texas kindergarten classroom
Estimating Direction of Arrival for Multi-Arm Spiral Antennas Using Machine Learning
No full textMilitary systems require monitoring a wide frequency range of the RF spectrum to detect and monitor enemy targets. A vital component of that is calculating the direction of arrival of enemy radars. The use of compressive sensing architectures like the Nyquist Folding Receiver (NyFR) allow for computationally cheap capturing of wideband signals; however, these techniques make traditional direction of arrival (DOA) estimation techniques difficult. Given the advantages of compressive sensing, this research aims to apply machine learning (ML) techniques to multi-arm spiral antennas to estimate the incoming DOA. Software like MATLAB was used to simulate the multi-arm spiral antenna and NyFR, allowing training of an ML algorithm using freely available tools like PyTorch
