Studies In Three-Component Modification Of Lysine, Investigating Reversible Potential Of An Intricate Bicyclo [3.3.1] Nonane Scaffold, Ryan Bartlett

Electronic Theses & Dissertations (2024 - present)

Synthesis of small-molecule conjugates capable of selective attachment to a peptide/protein backbone paves way for new therapeutic applications of protein modification. Sufficient inhibition or installation of function requires extensive design so the compound may identify and attach to the intended site. The utility of such an approach has prompted a number of applicable strategies and has rendered the development of new modification scaffolds less necessary. On the other hand, covalent modification to the biologics with ability to remove the conjugate via stimulus is underdeveloped, amplifying a current need to investigate the reversible potential for conjugation and deconjugation techniques in regard …

Androgen Regulation Of The Hpa Axis And Stress-Related Behaviors In Mice: The Role Of Crf And Crf Receptor 1, Krystyna Ann Rybka

Electronic Theses & Dissertations (2024 - present)

Mood disorders such as anxiety and depression are nearly twice as prevalent in women when compared to men, with potential contributing factors involving sex-dependent exposure to gonadal hormones and dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. Androgen actions through androgen receptors (AR) or actions at estrogen receptors such as ERα, following the conversion of androgens to estradiol, have been shown to regulate stress-related behaviors as well as HPA axis responsiveness. Where androgen actions at AR appear to decrease the stress response and subsequent stress-related behaviors, actions at ERα seem to do the opposite and increase HPA axis reactivity. When the HPA …

Re-Globalizing Yorkville: The Languages On Shop Signs In A Non-Migrant Neighborhood, Lisabeth G. Dashman

Electronic Theses & Dissertations (2024 - present)

The term “linguistic landscape” is used to describe the usage and placement of language in public places of a specific geographic area, such as on buildings, street names, pedestrian notices, vehicular warnings, and advertising billboards. Studies of a space’s linguistic landscape typically involve an accounting and analysis of the visible signs and/or the presentation of bystanders’ or researchers’ thoughts and observations. This study instead probes the intentions of the sign creators: the owners of the façade sign and the business it advertises. The façade sign, often called the shop sign, is frequently the first image for a business that a …

The Importance Of Ice Microphysics In Storm Electrification, Yichen Cai

Electronic Theses & Dissertations (2024 - present)

Evanescent but powerful, lightning is the vast scale release of storm energy from accumulation of minuscule cloud particle interactions. Although lightning occurrence seems random, thunderstorms “electrify” themselves in methodical ways and show structured patterns. This study explores the role of ice microphysics in thunderstorm charging and discharge through numerical simulation.

A squall line has been simulated ideally and realistically with generally consistent conclusions. Drastically different amount of lightning was produced when using three different microphysical models: Depending on the choice of charging scheme, the National Severe Storm Laboratory (NSSL) two-moment model appropriately captures or overestimate the amount observed by the …

Outcome-Based Patient-Therapist Matching Implementation: A Study Of Clinician Beliefs And Attitudes, Ashleigh Smith

Electronic Theses & Dissertations (2024 - present)

Background. Implementation science aims to identify methods that support the adoption of evidence-based practices (EBPs), including measurement-based care (MBC) and MBC-informed patient-therapist matching. Examining clinician attitudes can elucidate potential barriers to implementing EBPs, and attitudinal differences may exist across groups of therapists. In the context of a patient-therapist matching implementation project, this multi-method study investigated the relationship between clinician characteristics, attitudes toward EBPs/MBC, and implementation climate. Method. A sample of N = 72 therapists completed measures of demographic and clinical characteristics, attitudes toward EBPs, perceptions of implementation climate, and attitudes toward monitoring and feedback. A subset of N …

Protecting Foreign Victims Of Trafficking In Iceland: An Interpretive Analysis Of Policy Efforts, Hlin Saethorsdottir

Electronic Theses & Dissertations (2024 - present)

Social justice and human rights are fundamental principles of social work. Today’s globalized world requires social workers to expand their local perspectives and to be alert to the negative sides of globalization, such as trafficking in person (TIP), which affects all countries around the world. TIP is a severe form of exploitation and a grave human rights violation (Jones et al., 2007). Iceland has been categorized as a transit and destination country for foreign victims who are mainly trafficked for sexual and labor exploitation (U.S. Department of State, 2016b).

Although much has been written on TIP, some scholars have pointed …

Stakeholders’ Participation In Pcaob Audit Standard Setting, Xiaoshuai Yang

Electronic Theses & Dissertations (2024 - present)

Lobbying is an integral part of the Public Company Accounting Oversight Board’s standard-setting process. Although the PCAOB has been drafting auditing standards for over 20 years, there is still much to learn about how stakeholder behavior in submitting comment letters to the PCAOB varies by interest group, comment period (concept release, proposal, and reproposal), the stakeholder’s position on the proposal, arguments used, and emotional strategies. This paper examines PCAOB Docket 034, which proposed audit report reforms, including the auditor’s disclosure of critical audit matters (CAMs). There was strong stakeholder participation and conflicting opinions when this standard was under discussion. To …

Growing Up Sustainable? Politics Of Race And Youth In Urbanplan, Copenhagen, Max Ritts, Rebecca Rutt

Geography

This paper considers how racialized youth in Denmark negotiate sustainability amid contexts marked by intersecting forms of economic restructuring, progressive neoliberalism, white ethno-nationalism, and green urban planning. Urbanplan is a low-income, notoriously “troubled” Copenhagen neighborhood where we conducted fieldwork for 7 months (2019-2020) with fifteen male youth, aged 17-21. Using ethnography, policy reviews, and interviews with city social workers, we explore how intimate experiences of nature, group-identity, and place attachment here relate to and depart from the structural forces actively reshaping the neighborhood. Our analysis combines Cindi Katz's intersectional political economy approach with recent work on green gentrification, Critical Utopian …

Microwave Imaging Using A Radially-Polarized Probe, Matthew Dvorsky, Mohammed Tayeb Al Qaseer, Reza Zoughi

Patents

A microwave and millimeter wave imaging system. In either a far-field or a near-field detection mode, a radially-polarized probe transmits an imaging signal along a predetermined scan path to detect a target in a sample. The imaging signal's orientation is independent of the target's orientation and changes at each target as the probe transmits the signal during scanning. A measurement system receives scattered waves reflected from the sample via a single channel and images the sample and the target based on the reflected waves independent of the orientation of the target.

Enhanced Bottom Anode Monitoring In Dc Electric Arc Furnaces Using Fiber Optic Sensors, Yeshwanth Reddy Mekala, Rony Kumer Saha, Ogbole Collins Inalegwu, Muhammad Roman, Farhan Mumtaz, Rex Gerald, Jeffrey D. Smith, Jie Huang, Ronald J. O'Malley

PSMRC Faculty Research

A pin style bottom anode employs conductive steel rods that serve as the pathway for the high electrical power through rammed refractory at the bottom of a DC Electric Arc Furnace (EAF). Anode wear during operation is important to monitor, as anode replacement is expensive and impacts EAF productivity. Liquid steel penetration into the un-sintered refractory layer can result from rapid electrical power ramp-up, dips in furnace temperature, or operating the anode for too long between EAF campaigns. In extreme cases, the liquid steel may penetrate the bottom of the furnace when anode wear progresses too close to the bottom …

Extra-Legal Uses Of Tm, Clark Asay, Lareina Hingson, Stephanie Plamondon

Faculty Scholarship

Theoretical accounts of trademark law suggest that trademarks serve multiple marketplace functions, including protecting consumers and producers from unfair dealing, reducing consumer search costs, and incentivizing higher quality goods and services. Producers of goods and services often use the ‘TM’ symbol to signal their assertion of legal rights in a mark, arguably helping advance these goals. But recently, an interesting phenomenon has arisen in which individuals not engaged in typical commercial activities have been using the TM signifier in ways that don’t necessarily correspond to the symbol’s legal function. These so-called “extra-legal” uses of the TM symbol can offer insights …

Critical Theories, Justice, And The Rule Of Law, Adam J. Macleod

Scholarly Articles

An increasing number of legal scholars and activists now identify law as an impediment to justice that must be deconstructed. The deconstructionists tear down the resources we need to sustain the rule of law. And as they deconstruct law, they also deconstruct justice itself. Against deconstructionism, the classical tradition of jurisprudence that gave us our fundamental law affirms that we can know justice and that we can achieve justice through the establishment of law.

That classical tradition made possible the conviction that law is not a mere product of power, as the deconstructionists assert. And that conviction made the rule …

Freedom To Give, Devise, And Bequeath, Raymond C. O'Brien

Scholarly Articles

The ability to freely give, devise, or bequeath property is commonly thwarted by persons granted standing to contest formalities and intentionalities of wills, tortious interference with an expectancy, and expanding concern over intervivos gifts and trusts due to increasing elder financial abuse. Nonetheless, there is an expanding class of older, wealthy, and independent-minded donors who seek an effective means by which they may give their wealth to whomever they wish and bypass expensive legal fees, protracted litigation, loss of privacy, and the emotional drama of court proceedings. This Article offers a suggestion of how to restrict the possibility of contest …

The Favela Blossoms: Voices Of Favelas In São Paulo, Brazil, Vasti Cruz

Scripps Senior Theses

This project spotlights improvised housing in the peripheral areas of São Paulo, Brazil, better known as favelas. For over a century, the favela has been known as a place of death, violence, crime, and oppression. Paradoxically, the first favelas in Rio de Janeiro were named after a plant that produces flowers. However, today, these communities are rarely compared to their beautiful, symbolic-of-life namesake. Instead, this prejudgement is rampant not only globally, but also within the proper city– which perpetuates social division. When favelas are discussed in the media, they often reference those in Rio de Janeiro; however, favelas are present …

Communicating Through Dance: Examining Dance & Behavioral Therapy To Treat Selective Mutism, Clara Spitz

Scripps Senior Theses

Very little research has been done to examine the efficacy of treatments for adolescents with selective mutism (SM). Although cognitive behavioral therapy (CBT) has been distinguished as one of the optimal treatment styles for SM, a significant portion of research in this area has focused on children. Additionally, it often incorporates play therapy, which may not necessarily apply as effectively to older populations. Dance therapy has emerged as a promising and innovative treatment for various anxiety and communication issues. Although specific studies on its application to SM are limited, existing research suggests its potential effectiveness in addressing this condition as …
