High School Dropouts, Higher Education Dreams, And Achievement: A Six-Year Study Of A High-Stakes Test In Brazil, Eveline Miranda

Theses and Dissertations

Rumberger (2020) observed that "dropping out of school has economic and social consequences both for dropouts themselves and for the country as a whole" (p. 151). Every year, many Brazilians drop out of school due to work, early pregnancies, marriage, drug consumption, crime, etc. Dropping out of school can occur due to learning challenges, poor attendance, discipline problems, or a lack of access to high school institutions. Dropouts can experience depression and anxiety and are more likely to attempt suicide. The present dissertation includes two different papers about dropouts. The first paper uses fixed effect regression to show the main …

Structural Reasoning With Rational Expressions, Dana Steinhorst

Theses and Dissertations

Many students struggle to make sense of algebraic expressions in math. This lack of understanding results in students making symbolic manipulation errors, hindering their procedural fluency. Researchers believe these errors are linked to students' lack of structural reasoning. While research has shown that students rarely engage in expert structural reasoning, little is known about how students actually reason structurally. In this study, I interviewed six high school calculus students to study the way they identified, matched, and evaluated structures as they solved problems involving rational expressions and equations. I analyzed the participant interviews and outlined the matching process they used …

Teaching Social-Emotional Learning To Children With Autism Using Animated Avatar Video Modeling, Emelie Davis

Theses and Dissertations

People with a diagnosis of autism spectrum disorder (ASD) often have difficulties understanding or applying skills related to Social-Emotional Learning (SEL). An individual having a better understanding of SEL concepts is generally associated with more fulfilling connections with others and increased satisfaction in life. Since people with ASD tend to have greater success with learning in structured environments, we created a module to teach these skills using Nearpod. These modules were created with videos of a person embodying a cartoon dog face using Animoji for two reasons; because the animation was meant to appeal to children, and the creation was …

Determination Of A Catalytic Mechanism By Time Resolved Fourier Transform Infrared Spectroscopy And Time Domain Analysis Of Data From Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, Jacob T. Davis

Theses and Dissertations

Heterobimetallic catalysts offer large potential for efficient and selective catalysis of a wide range of reactions. Better understanding of these catalytic mechanisms could yield further improvement in their catalytic abilities. Cp(CO)2Fe-Cu(IPr) (IPr = N,N-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) is a catalyst that has been reported to catalyze arene borylation. The catalytic mechanism of this catalyst that had been previously proposed had the initial step being a metal-metal cleavage. However, computational modeling suggested an alternate mechanism that could be more energetically favorable. Rather than a metal-metal cleavage as the initial step, we proposed a photoactivated carbonyl dissociation. To support this proposition, we performed time resolved …

Zeros Of A Family Of Complex-Valued Harmonic Rational Functions, Alexander Lee

Theses and Dissertations

The Fundamental Theorem of Algebra is a useful tool in determining the number of zeros of complex-valued polynomials and rational functions. It does not, however, apply to complex-valued harmonic polynomials and rational functions generally. In this thesis, we determine behaviors of the family of complex-valued harmonic functions $f_{c}(z) = z^{n} + \frac{c}{\overline{z}^{k}} - 1$ that defy intuition for analytic polynomials. We first determine the sum of the orders of zeros by using the harmonic analogue of Rouch\'e's Theorem. We then determine useful geometry of the critical curve and its image in order to count winding numbers by applying the harmonic …

Explaining Suharto's Rise And Fall: International And Domestic Variables, Julia Batanghari

Undergraduate Honors Theses

For three decades (1968-1998), Indonesia was led by President Suharto, whose authoritarian military regime is remembered for its corruption and brutality. This paper offers an analysis of Suharto’s rule through the lens of two events: his 1965 purge of local ‘communists’ and the riots of May 1998. Drawing comparisons between the two, I delve into systemic causes by considering the influence of domestic and international variables. Exploring links between intergroup accommodation and democracy reveals that Suharto’s lack of ethnic, socioeconomic, and religious inclusivity paved the way not only for the anti-Chinese sentiment which pervaded Indonesian society during his presidency, but …

A Preliminary Assessment Of Compassion Fatigue In Chimpanzee Caregivers, Mary Lee A. Jensvold

Anthropology and Museum Studies Faculty Scholarship

Compassion fatigue is defined as “traumatization of helpers through their efforts at helping others”. It has negative effects on clinicians including reduced satisfaction with work, fatigue, irritability, dread of going to work, and lack of joy in life. It is correlated with patients’ decreased satisfaction with care. Compassion fatigue occurs in a variety of helping professions including educators, social workers, mental health clinicians, and it also appears in nonhuman animal care workers. This study surveyed caregivers of chimpanzees using the ProQOL-V to assess the prevalence of compassion fatigue among this group. Compassion satisfaction is higher than many other types of …

Bis-Indolyl Compounds And The Induction Of Apoptosis In T98g Glioblastoma Multiforme Cells, Margot C. Brown

Seton Hall University Dissertations and Theses (ETDs)

1,1-bis(3’idolyl)-1(aryl)methane compounds (BIM compounds) have been shown to have anti-cancer properties in colon cancer, bladder cancer, and leukemia cells. The purpose of this work was to determine if BIM compounds could be an effective treatment of glioblastoma multiforme. Sulforhodamine B (SRB) assays showed that 20µM of the BIM compounds could inhibit cellular proliferation of the T98G glioblastoma multiforme cell line over 72 hours. Then immunoblotting was used to analyze the molecular pathway induced by BIM compounds. An increase in the expression of both BAX and cleaved caspase 3 suggest BIM compounds activate programmed cell death, or apoptosis in glioblastoma cells. …

Understanding The Experiences Of African American Caregivers Of Loved Ones With Dementia, Paula R. Madison

Seton Hall University Dissertations and Theses (ETDs)

Background: Dementia is a public health problem that is estimated to triple by 2050.Globally, dementia is the seventh leading cause of death among all diseases and one of the major causes of disability and dependency among older people. The direct medical costs and indirect social and economic costs of dementia are burdensome to society, and by 2030 it is projected to cost more than $2.8 TRILLION dollars worldwide. African Americans are two to four times more likely to be diagnosed with dementia than White Americans; and more likely to rely on informal care from family and friends. African …

F-Box Receptor Mediated Control Of Substrate Stability And Subcellular Location Organizes Cellular Development Of Aspergillus Nidulans, Bayram Ö Sarikaya, Ö Bayram, B Karahoda, C Meister, Am Köhler, S Thieme, N Elramli, D Frawley, J Mcgowan, Da Fitzpatrick, K Schmitt, Leandro Jose De Assis, O Valerius, Gh Goldman, Gh Braus

Peninsula Medical School

Fungal growth and development are coordinated with specific secondary metabolism. This coordination requires 8 of 74 F-box proteins of the filamentous fungus Aspergillus nidulans. F-box proteins recognize primed substrates for ubiquitination by Skp1-Cul1-Fbx (SCF) E3 ubiquitin RING ligases and degradation by the 26S proteasome. 24 F-box proteins are found in the nuclear fraction as part of SCFs during vegetative growth. 43 F-box proteins interact with SCF proteins during growth, development or stress. 45 F-box proteins are associated with more than 700 proteins that have mainly regulatory roles. This corroborates that accurate surveillance of protein stability is prerequisite for organizing multicellular …

Single-Shot, Ultrafast, Multi-Frame X-Ray Imaging Of Defect-Bearing Ablator Materials In Extreme Conditions, Daniel S. Hodge

Theses and Dissertations

Characterization of the dynamic behavior of defect-bearing ablator materials subjected to extreme conditions is essential in advancing fusion energy as an reliable and abundant energy source. By understanding how materials evolve spatially and temporally we can minimize hydrodynamic instabilities, which are major contributing factors to energy yield degradation in inertial confinement fusion (ICF) experiments. In this thesis we demonstrate the capabilities of an ultrafast x-ray imaging (UXI) detector, the Icarus V2, where we capture multiple frames of single void-bearing sample compressed by a high-intensity laser shockwave. Using the Matter in Extreme Conditions (MEC) instrument at the Linac Coherent Light Source …

Creating An Instrument To Explore The Self-Efficacy Of Writing Instructors To Teach Apprehensive Writers, Kathleen Marie Romrell

Theses and Dissertations

Writing apprehension is a writing difficulty that can impair the writing experiences of students. While researchers have proposed many interventions that teachers can implement to assist their students who struggle with writing apprehension, there has not been an instrument that is designed to measure teacher self-efficacy to help these same students. This study created such an instrument, entitled the Self-efficacy to Teach Apprehensive Writers Scale (STAWS), using Tschannen-Moran and Woolfolk Hoy’s (2001) Teacher Sense of Efficacy Scale and Daly and Miller’s (1975) Writing Apprehension Test as model instruments. The new instrument was designed to measure writing instructor self-efficacy to teach …

Delivering Explicit Math Instruction Through Point-Of-View Video Modeling To Elementary Students With Autism Spectrum Disorder, Patsy Mccray Gibbs

Theses and Dissertations

There is significant literature demonstrating the effectiveness of video modeling for teaching skills to students with disabilities. Still, much less is known about how video modeling, particularly point-of-view video modeling (POV-VM), might be applied to teach academic skills to children with an autism spectrum disorder. This multiple probe single-case design study used explicit instruction techniques to teach multiplication, division, and fraction skills to two elementary-aged students with an autism spectrum disorder. A visual analysis of the data showed that POV-VM using explicit techniques to deliver the videos is an effective intervention for autistic students This research study adds to the …

Our understanding of how osteocytes, the principal mechanosensors within bone, sense and perceive force remains unclear. Previous work identified "tethering elements" (TEs) spanning the pericellular space of osteocytes and transmitting mechanical information into biochemical signals. While we identified the heparan sulfate proteoglycan perlecan (PLN) as a component of these TEs, PLN must attach to the cell surface to induce biochemical responses. As voltage-sensitive calcium channels (VSCCs) are critical for bone mechanotransduction, we hypothesized that PLN binds the extracellular α2δ1 subunit of VSCCs to couple the bone matrix to the osteocyte membrane. Here, we showed co-localization of PLN and α2δ1 along …

Decision-Based Learning As A Tool For Teaching Statistics In A Peruvian University, Gloria Mora Barba

Theses and Dissertations

Many students find that learning statistics is difficult, especially novice learners first taking statistical classes. Instructors also struggle to teach statistics due to many challenges, such as students' misconceptions, lack of math skills, negative attitudes, and deficient instructional methods. A new pedagogical approach called Decision-Based Learning (DBL) has been developed to help instructors and students overcome these challenges. A group of Peruvian university professors in 2018 and 2019 were trained to use DBL. However, limited studies have explored DBL instructors' and students' experiences using DBL in Peru. The aim of this qualitative research study is to deeply understand the experiences …

Outdoor Recreation And Its Effect On Our Relationship With The Environment, Martin Brannaman

Department of Environmental Studies: Undergraduate Student Theses

This study was conducted at the University of Nebraska Outdoor Adventure Center. This study employed a pre-post retrospective assessment looking at individuals' connection with nature after embarking on a direct outdoor experience. A direct outdoor experience is when an individual is outside and not surrounded by manmade structures (Kil, 2016). I believe that after a direct outdoor experience the sample group will have a significant change in their connection to nature. The objective is to measure change in a group's connection to nature, through the Connectedness to Nature Scale (CNS, Mayer & Frantz, 2004). The population was a group of …

Quantifying Shape Variation In An Antisymmetrical Trait In Xenophallus Umbratilis, Mary-Elise Johnson Nielsen

Theses and Dissertations

Antisymmetry is a striking, yet puzzling form of biological asymmetry. The livebearing fish Xenophallus umbratilis exhibits antisymmetry in the male intromittent organ and provides a system that is well-suited for studying the nature of variation in antisymmetrical traits. Using geometric morphometrics, I test the hypothesis that because the gonopodium is critical to fitness there will not be significant differences in gonopodium shape between the two gonopodial morphs in this species. My results are consistent with this prediction, though I found that gonopodium shape did differ with gonopodium size.

Identity Work To Teach Mathematics For Social Justice, Navy B. Dixon

Theses and Dissertations

In this thesis, mathematics educators are conceptualized as individuals with multiple, simultaneous figured worlds that inform their decisions while planning. The study explores how two mathematics educators negotiated and orchestrated their figured worlds to plan two mathematics lessons for social justice. The results highlight how numerous the figured worlds each participant surfaced through background interviews. Some of the figured worlds were elicited by the interview questions (i.e., Race, Family, Social Justice Teaching) but other figured worlds organically surfaced through the interviews (i.e., Sexuality, Community, Activism, Critical Information Consumption). A discursive analysis of a selection of these figured worlds revealed conceptualizations …

The Pendulum Of Juvenile Justice Policy: Examining The Creation And Implementation Of New York State’S Raise The Age Legislation, Mary Xitco

Theses

This paper discusses changes in juvenile justice policy, focusing largely on the last 40 years. Juvenile justice policy has historically transitioned quickly from conservative punitive strategies to liberal rehabilitative and lenient strategies. We see this most recently with the tough on crime strategies of the 1990s lowering the age of responsibility to now where states have decided to start raising the age of criminal responsibility up to 18 years old. This paper looks closely at what caused this most recent shift and gives historical context as to how juvenile justice policy trends may have predicted this.

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson

Public Administration Faculty Publications and Presentations

This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

The Common Law As Statutory Backdrop, Anita S. Krishnakumar

Georgetown Law Faculty Publications and Other Works

Amidst the whirl of commentary about how the U.S. Supreme Court has become increasingly textualist and what precise shape modern textualism should take, the Court’s continued reliance on one decidedly atextual interpretive tool has gone largely unnoticed — the common law. Indeed, the common law has played an underappreciated, often dispositive, gap-filling role in statutory interpretation for decades, even as the textualist revolution has sidelined other non-text-focused interpretive tools. But despite the persistent role that the common law has played in statutory interpretation cases, the use of common law rules and definitions as an interpretive resource is surprisingly understudied and …

3D patient tumor avatars (3D-PTAs) hold promise for next-generation precision medicine. Here, we describe the benefits and challenges of 3D-PTA technologies and necessary future steps to realize their potential for clinical decision making. 3D-PTAs require standardization criteria and prospective trials to establish clinical benefits. Innovative trial designs that combine omics and 3D-PTA readouts may lead to more accurate clinical predictors, and an integrated platform that combines diagnostic and therapeutic development will accelerate new treatments for patients with refractory disease.
