Testing Microscopic Approaches For Cementochronology In The 21st Century Identified Skeletal Collection, Portugal, Amando Luis Montalvo Jr.

Theses and Dissertations

Age-at-death estimation is a key component to the creation of a biological profile in forensic anthropology. Acellular extrinsic fiber cementum annulations have been shown to correlate with chronological age. Cementochronology examines this correlation through the sum of the alternating translucent bands and opaque annuli, and the age of eruption of a tooth. While several microscopy techniques have been used, there is no consensus on the most optimal. This study will assess the reliability, precision and accuracy of three microscopy techniques: Brightfield (BF), Phase Contrast (PC) and Differential Interference Contrast (DIC). PC was the most reliable (rTEM= 10.4%), the most precise …

Youth Attitudes And Perceptions Regarding Police, Courts, And Political Engagement: A Texas Study, Marika Dawkins-Cavazos, Camille Gibson, Yudu Li

Criminal Justice Faculty Publications

Youth are often perceived as disengaged from civic and political processes, yet their potential to influence elections is receiving increasing attention. This study examined how differences in race, ethnicity, sex, and age shape youth civic engagement, particularly their willingness to vote in the 2024 presidential election. Through surveys of college students in the diverse southern region of the United States, the research explored the relationship between perceptions of law enforcement, trust in the justice system, and civic participation. Specifically, it hypothesized that Black and Hispanic youth would report lower trust in law enforcement, which may influence their willingness to engage …

Police Chief Turnover In Texas: Do Institutional Environments Matter?, Yudu Li

Criminal Justice Faculty Publications

The field of organizational studies has extensively examined factors influencing the turnover and succession of public officers, yet limited attention has been given to chiefs of police. Using institutional theory as a framework, this study explores police chief turnover by focusing on the institutional environment and the relationships between police chiefs and key individuals and entities within their communities. Utilizing survey data collected from police chiefs attending mandatory training programs designed for new appointees, the analysis reveals that police chief turnover is substantially associated with the quality of relationships with key stakeholders within the institutional environments, both individually and collectively. …

Barriers To Hispanic Post-Secondary Education In Science Fields, Luis Slayton

Theses and Dissertations

The study aimed to examine whether external barriers could be identified and are present throughout a Hispanic individual's educational life. The beliefs of the Hispanic community regarding education and the nature of acquiring an education could be relevant to the factors that impede the completion of high school. A survey approach was chosen as the methodology for the study due to the confidential nature of a questionnaire. Human nature tends to be more honest when not asked personal questions face-to-face. Additionally, there is potential to generalize attributes from a small sample to a larger population, allowing inferences about the identified …

Understanding Youth Violence Through A Socio-Ecological Lens, Yok-Fong Paat, Kristopher Hawk Yeager, Erik M. Cruz, Rebecca Cole, Luis R. Torres-Hostos

School of Social Work Faculty Publications

Youth violence—the deliberate use of physical force or harm by young people between the ages of 10 and 24 to intimidate or cause harm to others, both online and offline—is a critical public health issue in the United States. Yet, successfully predicting future violent offenders is a complex and challenging task, as the question of why some youths resort to extreme violence while others refrain from it—despite facing similar risk factors—remains widely debated. This article highlights both risk and protective factors of youth violence through a socio-ecological lens to offer a comprehensive understanding of the multifaceted factors driving youth violence …

Latine Students’ Stem Identity Development: Reflecting On Implicit Biases, Imposter Syndrome, Self-Efficacy, And Support Systems, Alyssa G. Cavazos, Valerie Leija, Javier Cavazos Vela

This study used an equity ethic framework and a STEM identity model to contextualize and understand Latine students’ perceptions of STEM identity development. The purpose of this study was to investigate how Latine undergraduate students who engaged in STEM coursework perceived their learning experiences and stories of resilience through an equity ethic framework. Data were collected through interviews with 19 Latine college students attending a Hispanic-Serving Institution. Findings revealed the following themes related to Latine students’ STEM identity development and lived experiences in STEM coursework: implicit biases, imposter syndrome, self-efficacy, and support system and resources. Findings highlight the need for …

Identification Of Cadmium As A Structural And Functional Modulator Of Psd-95 Regulating Nmdars At Postsynaptic Membranes, Claudia Garza

Theses and Dissertations

Postsynaptic density-95 (PSD-95) is an essential scaffolding protein in excitatory neurons. PSD-95’s N-terminal palmitoylation region elicits synaptic plasticity by targeting, anchoring, and trafficking glutamate receptors, such as N-methyl-d-aspartate receptors (NMDAR), to the postsynaptic membrane. The molecular interactions of PSD-95 and its dysregulation in excitatory synapses are currently being explored as primary causes of neurodegenerative diseases and disorders, such as Alzheimer’s disease, Schizophrenia, and Parkinson’s disease. Recent studies demonstrate an overaccumulation of zinc at two cysteines (C3 and C5) and two histidines (H24 and H28) of PSD-95 blocks palmitoylation, causing a loss of NMDAR at the postsynaptic membrane. In addition, exposure …

The Effects Of Placing Students In Special Education In A Disciplinary Alternative Education Program, Daniel Garza

Theses and Dissertations

Educating students with special needs can be very challenging especially when their academic challenges are compounded with behavioral challenges. Disciplining students with special needs can create additional challenges and often the use of punishment can have little to no effect in deterring undesirable behavior. As behaviors escalate, so does the form of punishment and students with special needs are often sent to a Disciplinary Alternative Education Program. This study aimed to uncover the effects of placing students who receive special education services in a Disciplinary Alternative Education Program focusing on the impact of placements on academic outcomes and behavioral changes. …
