Effect Of Thickness On Structural, Morphological, And Optical Properties For Nanocrystalline Thin Films Of Cd1-Xsnxs, For Optoelectronic Applications, Lamia K. Abbas

Baghdad Science Journal

Thin films of Sn1-xCdxS nanocrystals (X=0,0.7, and 1) with different thicknesses 200, 300, and 400 nm were prepared on glass bases at 300 C by the participation method and chemical spray pyrolysis method (CSP). The effect of the concentration of Sn and thickness on the structural and optical properties of the prepared films was studied. The films were characterized to evaluate the structure, transmittance, and optical energy band gap. X-ray diffraction (XRD) studies showed that the films were polycrystalline with hexagonal and orthogonal structures. XRD and atomic force measurement results showed that the grain size increases with its thickness. The …

Daca’S Stratified Tracks For Economic Mobility And Lessons For Addressing Immigrants’ Long-Term Inequality, Els De Graauw, Shannon Gleeson

UC Law Journal

Since 2012, the politically tenuous Deferred Action for Childhood Arrivals (DACA) program has provided temporary deportation relief and work authorization to over eight hundred thirty-five thousand undocumented young people who fit certain criteria. This Essay draws on one hundred fifteen interviews with DACA applicants in California, New York, and Texas during the heyday of the program to better understand its impacts on recipients’ school and work experiences. We confirm many of the key benefits DACA status has provided to recipients, notably opening doors for them educationally and professionally.

However, our research also confirms DACA’s uneven impacts. Those without four-year college …

The Racial Triangulation Of Asian American Achievement, Vinay Harpalani

UC Law Journal

This Essay employs Professor Claire Jean Kim’s racial triangulation framework to examine how Asian Americans are racialized via academic achievement. It argues that there are two components to the racial triangulation of Asian American achievement. On one hand, Asian Americans are valorized as a “model minority”. We are praised for our achievement and cast as a model for other groups of people of color to follow. This ignores both the different histories of oppression that various groups of color have faced and the vast diversity of experiences among Asian Americans. But on the other hand, Asian Americans are also viewed …

The Kkk, Immigration Law And Policy, And Donald Trump, Kevin Johnson

UC Law Journal

Many Americans know the Ku Klux Klan (KKK) for its horrific acts of violence directed at African Americans. Although generally overshadowed by that violence, the KKK’s vilification of other groups, including immigrants and religious minorities, long has been central to its quest for white Anglo-Saxon supremacy. This Essay analyzes the enduring legacy of the KKK’s immigration philosophy on contemporary American immigration law and politics. Some modern anti- immigrant advocates champion remarkably similar policies to the Klan’s with racial animus on full display. Former President, and the 2024 Republican nominee for President, Donald Trump is an example.

The Importance Of Counting All Immigrants For Apportionment And Redistricting, Tye Rush, Samuel Hall, Matt A. Barreto

UC Law Journal

How are non-citizens counted and accounted for in representation? Section 2 of the Fourteenth Amendment requires that all whole persons residing in a state are to be counted for apportionment and districting. Courts have interpreted Section 2’s requirement to include women (before the Nineteenth Amendment), non-citizens, and people under 18 years old. Yet today, some states are attempting to exclude non-citizens from apportionment and representation by using a citizen population calculus. This stands in contrast to more than 225 years of practice and to nearly all modern legal interpretations of representation. In landmark 1960s cases such as Wesberry v. Sanders …

Political Representation And Economic Rights In The Shadows Of Citizenship, Allison Brownell Tirres

UC Law Journal

In recent years, the remarkable movement for the political rights of undocumented youth—the so- called “DREAMers”—has catalyzed a critical conversation about the economic rights of all noncitizens. A growing number of states have amended their laws in response to advocacy by and for this particular group of noncitizens. This Essay situates this modern legal development in a broader conceptual and historical frame. It reflects on the relationship between economic rights and political aspirations in this movement, as well as in two other key legal developments in immigration history: the passage of anti-Asian alien land laws in the 1910s and 1920s, …

The Impact Of Bruen And Its Expansion Of The “Right To Carry” On Terry As A Law Enforcement Tool, Kshitij Mehta

UC Law Journal

In New York State Rifle & Pistol Association, Inc. v. Bruen, the Supreme Court expanded the right to carry firearms, specifically handguns, outside the home. Due to the Court’s conservative rulings, combined with lax and open firearm regulatory regimes in several jurisdictions, gun violence continues to create catastrophic consequences in communities across the country. At the same time, law enforcement agencies already struggle to maintain public safety and public trust under current policing systems. With the rise of firearms in the streets, law enforcement will likely resort to, and double down on, their current use of stop and frisk under …

Self-Efficacy And Attitudes Associate With Undergraduates’ Library Research Intentions: A Theoretically-Grounded Investigation, Alex Pfundt, Laurel M. Peterson

Psychology Faculty Research and Scholarship

Undergraduates’ use of academic libraries is associated with academic achievement, but library research resources are underutilized, and little is known about what factors contribute to students’ use of these resources. A random sample of undergraduate students from a historically women’s college in the United States (N = 207; 59.2% white; 87.7% female or transfemale, 5.9% gender queer, 5.9% gender non-conforming, and 0.5% other gender) reported on their information literacy self-efficacy, attitudes toward research in undergraduate courses, and behavioral intentions to engage with library resources and services using an anonymous online questionnaire. Controlling for past library research and class year, …

Cortical And Subjective Measures Of Individual Noise Tolerance Predict Hearing Outcomes With Varying Noise Reduction Strength, Subong Kim, Susan Arzac, Natalie Dokic, Jenn Donnelly, Nicole Genser, Kristen Nortwich, Alexis Rooney

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Noise reduction (NR) algorithms are employed in nearly all commercially available hearing aids to attenuate background noise. However, NR processing also involves undesirable speech distortions, leading to variability in hearing outcomes among individuals with different noise tolerance. Leveraging 30 participants with normal hearing engaged in speech-in-noise tasks, the present study examined whether the cortical measure of neural signal-to-noise ratio (SNR)—the amplitude ratio of auditory evoked responses to target speech onset and noise onset—could predict individual variability in NR outcomes with varying strength, thus serving as a reliable indicator of individual noise tolerance. In addition, we also measured subjective ratings of …

The Presence Of Diversity Initiatives Leads To Increased Pro-White Hiring Decisions Among Conservatives, Zeinab A. Hachem, Tessa L. Dover

Psychology Faculty Publications and Presentations

Despite the push and pull between pro-diversity advocates and conservative resistance, most organizations have implemented diversity initiatives in an effort to promote equitable and fair organizational practices. Past work has shown that these diversity initiatives may not be as effective as expected and may instead result in unintended negative consequences for the very individuals they are meant to support. In three novel experiments (total N = 3,664), we investigated whether and when the presence of pro-diversity messages in organizational job recruitment materials might facilitate versus hinder the hiring of underrepresented racial minorities. Participant race and political ideology were also investigated …

Analysis Of Malarial Impact: Understanding Disease Transmission, Epidemiology, And Effects On Fetal Life, Josey Sumpter

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Malaria is a significant public health problem which mainly affects malaria endemic regions, such as parts of Africa, South America, and Western Asia. However, all hot and humid environments are susceptible to spread leading to a global scale. Malaria affects an estimated 200 million people each year, with about 600,000 cases resulting in death. Malaria is passed through the bites of infected female anopheles mosquitos, with one of the six Plasmodium genus parasites that are malarial causing. Once the parasite enters the blood stream it infects erythrocytes which can then spread throughout the entire body. Disease is often characterized by …

Documenting The Spatial And Temporal Dynamics Of Pair-Rule Genes In The Early Tribolium Embryo, Hasan Mahmud

Theses and Dissertations

Although Insects and vertebrates have different anatomical structures, they possess similar mechanisms for segmenting during embryogenesis. Clock and wavefront model exhibit a similar pattern of division as observed in Drosophila, like vertebrates, which emphasizes fundamental principles in the field of developmental biology. In contrast to Drosophila, the insect Tribolium castaneum exhibits posterior segmentation originating from the growth zone. The pair-rule genes’ expression is characterized by oscillatory patterns, which are controlled by a segmentation clock. Researchers found that the speed regulation model combines oscillatory and sequential gene activities to shape both elongating and non-elongating embryonic tissues. The adaptability of this model …

Biometric Assessment Of Spotted Seatrout (Cynoscion Nebulosus) From Recreational And Commercial Fisheries In Mississippi, Usa, Nimah Folake Osho-Abdulgafar

Master's Theses

Quantitative stock assessments for Mississippi’s Spotted Seatrout use length-, age-, and sex-composition data from fishery-independent sources as proxies to estimate biostatistical characteristics of fisheries harvests due to lack of sector-specific data. In Chapter 2, I examined the age, length, and sex composition of Spotted Seatrout from three fishery-dependent sectors. Between April and December 2023, I collected 210 fish (n = 19, 124, and 67 from private, charter, and commercial sectors, respectively). The length ranged between 373-535mm, 285-523mm, and 345-568mm TL, with mean ± SD lengths of 453 ± 51mm, 393 ± 57mm, and 442 ± 53mm TL, respectively. Age ranged …

An Examination Of The Strong Start Intervention To Support The Pro-Social Behaviors In At-Risk Head Start Students, Merrick Mcevoy

Master's Theses

Children from lower-income and diverse families are at a higher risk for social-emotional and academic difficulties. Implementation of early childhood interventions plays a crucial role in the healthy development of children’s social-emotional development. Merrell’s Strong Kids (Merrell et al., 2009), a commonly used SEL class-wide intervention, facilitates learning of the five core SEL components through weekly lessons and has been shown to have long-term improvements on children’s internalizing symptoms, social and emotional knowledge, student-teacher relationships, prosocial behaviors, and is well received by teachers. The current study examined the efficacy of Strong Kids implemented as a one-on-one intervention, rather than a …

Integration Of Matlab And Machine Learning To Accelerate Evaluation Of Biological Activity In Agricultural Soils And Promote Soil Health Improvement Goals, Andrew Stiven Ortiz Balsero

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Traditionally, assessments of soil biological activity have been confined to laboratory settings, creating a disconnect with practical in-field methods. To bridge this gap, cotton fabric degradation has been used to illustrate soil microbial activity under different management practices. While effective, these demonstrations are subjective and labor-intensive.

Researchers have explored using image processing software like ImageJ and Adobe Photoshop to streamline this process. Although these tools accurately quantified fabric degradation under varying soil conditions, the methods remained labor-intensive and complex. Consequently, these methods were still not ideal for on-farm use by agricultural practitioners.

To further address labor and complexity limitations, the …

A Study Of Commuting Conditions For Construction Professionals In The San Francisco Bay Area, Ethan John Argue

Construction Management

This paper investigates the commuting experiences of workers in the San Francisco Bay Area, with a focus on construction industry professionals. Numerous scientific studies and reports have been done regarding both traffic congestion in the Bay Area and commuting conditions for construction workers. By comparing points of information on Bay Area workers like their job type, commute length and commute satisfaction, this study aims to uncover correlations and understand who is affected the most by traffic congestion. After extensive surveys and interviews of Bay Area workers, average commute times were calculated and reported for several industry subsets, along with averages …

Development And Validation Of Aronia Melanocarpa Berry Recipes For Home Canning: Integrating Thermal Lethality Studies, Microbiological Safety, And Antioxidant Analysis, Juan Diego Villegas Posada

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Aronia melanocarpa, also known as chokeberry, is gaining popularity for its high antioxidant content and health benefits, including reducing oxidative stress and inhibiting cancer gene expression. However, its characteristic bitterness and astringency limit its broader appeal. Chokeberry's low pH places it in the acid foods category, making it ideal for safe home canning. An acidic environment combined with heat treatment inhibits harmful bacteria like Clostridium botulinum. Home canning preserves food by sealing it in airtight containers and heating it to destroy spoilage microorganisms.

Developing safe and palatable recipes is essential for making chokeberries suitable for home canning. A …

Candida Albicans Farnesol Synthesis And Secretion, Daniel John Gutzmann

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Candida albicans is a polymorphic fungus and opportunistic commensal found primarily in the gastrointestinal and skin of healthy individuals. Several barriers prevent C. albicans from causing disease including a healthy immune system and microbiome. When these barriers become comprised, C. albicans can transition to a pathogen and disseminate through the intestinal mucosa leading to life-threatening bloodstream and invasive infections with mortality rates of up to 64%. Morphogenic plasticity is key to this transition and impacts virulence, adaptation to different host environments, and evasion of host immune responses. One regulator of morphogenesis is farnesol. Farnesol is a secondary metabolite …

Praying To Tiktok, Seeking The Self: How Rhetoric Reveals And Conceals The World’S Most Powerful Guru Of The Postindustrial Age, Samantha L. Gillespie-Hoffman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Imagine a world where the most powerful leader is a wellness guru that runs an elaborate church with millions of followers. The guru is so powerful that everyone believes they can read minds and make ordinary people rich and famous. The guru controls forms of communication, media channels, consumer tastes, and what people eat, drink, say, and even think. What if this guru was not human but actually an algorithm? Does this sound like the plot of a science fiction novel? I argue that this scenario is closer to reality than most will admit. In this project, readers encounter a …

Phylogenetic And Biogeographic Patterns Of Devonian Proetid Trilobites, Katherine Jane Jordan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ecological disruption events such as mass extinctions can result in the permanent alteration in clades and ecosystems. A pivotal time of change during the history of life on Earth can be seen in the Devonian Period. During this time, major transitions in marine and terrestrial system resulted in a different world at the end of the period in comparison to the beginning. One such group most heavily impacted were trilobites. Trilobites were reduced to one order by the end of the Devonian: Proetida. My dissertation focuses on phylogenetic, biogeographic, and paleocommunity patterns of this group, known as the last of …

The Benefits Of Biofouling – Promoting The Growth Of Benthic Organisms To Enhance Ecosystem Services, Kailey Nicole Richard, Kelli Z. Hunsucker, Travis J. Hunsucker, Geoffrey Swain

Ocean Engineering and Marine Sciences Student Publications

For the marine industry biofouling has a negative reputation. On ship hulls, the accumulation of these unwanted plants and animals can lead to increased drag, fuel consumption, and greenhouse gas emissions. Offshore platforms are also subject to biofouling which can result in corrosion and hydrodynamic loading, thus shortening their lifespan. While the harmful impacts of biofouling are commonly reported throughout the literature, biofouling can also benefit both aquatic and human populations. Common biofouling organisms act as natural filtration systems, thus improving water quality. Many of the same flora and fauna serve as a food source, and structures could be designed …

Institutional Design Of Intergovernmental Organizations: Cooperation, Vitality, And Evolution, Darrell James Carter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Intergovernmental organizations (IGOs) are critical institutions in the international system through which states cooperate and compete. Much scholarship has examined the role and operation of IGOs, but many questions about how they facilitate cooperation, their vitality, and their evolution remain. The functions of IGOs are impacted by their institutional design, which then affects operation and vitality. IGO’s perform their roles through multiple mechanisms that facilitate state interaction. IGOs enable states to overcome credibility issues and cooperate. The institutional design of IGOs, their membership, their resources, and their institutionalization, all impact the functioning of the IGO. I examine empirically how joint …

Relationships Between Psychopathology, Impulsivity, And Disordered Eating, Repairer Etuk

UNLV Theses, Dissertations, Professional Papers, and Capstones

Impulsivity is defined by behaviors that are often performed without foresight or consideration for consequences. For some individuals, impulsive behaviors are excessive or dysfunctional, and can become extremely problematic, ultimately leading to impairments in quality of life and lowered psychological functioning. Impulsivity is a multifaceted factor, comprising several different domains that have been explored in past studies (e.g., trait impulsivity, decision making, response inhibition). However, previous research shows that trait impulsivity in adults is consistently associated with several psychiatric problems including substance abuse, eating disorders, and compulsive sexual behaviors. To date, few studies have investigated impulsivity, compulsive sexual behavior. disordered …

Gender Stereotyping In An Agricultural Sample, Andrea Fink-Armold

UNLV Theses, Dissertations, Professional Papers, and Capstones

A vast wealth of social psychological research conducted over half a century has demonstrated the consequences of gender stereotypes. However, this research has significant limitations. Namely, generalizability outside of academia and the effects of social change. This study examined a non-academic population that has recently experienced significant gender role redistribution to overcome these limitations. Utilizing a full-cycle research approach consisting of both ethnographic and experimental methods, I examined three research questions: 1) how do gender stereotypes manifest within rural agricultural communities? 2) how is women’s increased participation in agriculture related to changes in gender stereotype use? and 3) how do …
