Teaching About Black Adolescents’ Exposure To Trauma: A Mixed Methods Study, Bridget E. Weller, Winifred Wilson, Jaimie E. Sullivan, Brittney E. Ivy, Bakari A. Wallace Jan 2024

Teaching About Black Adolescents’ Exposure To Trauma: A Mixed Methods Study, Bridget E. Weller, Winifred Wilson, Jaimie E. Sullivan, Brittney E. Ivy, Bakari A. Wallace

The Journal of Sociology & Social Welfare

Black adolescents are exposed to race-based forms of historical, structural, cultural, and interpersonal dimensions of trauma. However, social work educators have little evidence-based guidance on how to teach this content in a way that improves graduate students’ sense of self-efficacy (i.e., belief in their ability) to work with Black adolescents who experience trauma. The purpose of this sequential mixed methods study was to examine and understand possible reasons for changes in students’ self-efficacy after completing a graduate-level, elective course in social work that aimed to prepare students to professionally work with Black adolescents who experienced trauma. Quantitative findings from a …

Purpose: Cancer deaths in low- and middle-income countries (LMICs) will nearly double by 2040. Available evidence-based interventions (EBIs) for cancer prevention and early detection can reduce cancer-related mortality, yet there is a lack of evidence on effectively scaling these EBIs in LMIC settings.

Methods: We conducted a scoping review to identify published literature from six databases between 2012 and 2022 that described efforts for scaling cancer prevention and early detection EBIs in LMICs. Included studies met one of two definitions of scale-up: (1) deliberate efforts to increase the impact of effective intervention to benefit more people or (2) an intervention …

Using Focus Groups To Explore Older Black Men's Perception Of Dietary Interventions., Ashley R Shaw, Eric D Vidoni, Mickeal N Key, Brandon A Yates, Roland Thorpe

Faculty, Staff and Student Publications

Older Black men are underrepresented in research despite being disproportionately affected by Alzheimer’s disease (AD) and cardiovascular (CV) risk factors related to AD compared with non-Hispanic Whites. Although dietary interventions have shown promise to reduce modifiable CV risk factors related to AD, Black Americans have lower adherence likely due to lack of cultural considerations. Using a noninterventional convergent parallel mixed-methods approach, this study examined the cultural contexts that inform perceptions of dietary interventions among older Midwestern Black men. All participants completed an online demographic and dietary habit survey prior to focus group discussions. Two focus group discussion sessions were conducted …


An Exploration Of Anxiety And Depressive Symptoms Among Sexual And Gender Minority Young Adults Visiting A Drop-In Center For Youth Experiencing Homelessness, Lourence Misedah-Robinson, Laura Witte, Elizabeth Henneke, Madonna Land, Vanessa Schick Jan 2024

An Exploration Of Anxiety And Depressive Symptoms Among Sexual And Gender Minority Young Adults Visiting A Drop-In Center For Youth Experiencing Homelessness, Lourence Misedah-Robinson, Laura Witte, Elizabeth Henneke, Madonna Land, Vanessa Schick

Faculty, Staff and Student Publications

Background: Research suggests that marginalized young adults, particularly sexual and gender minorities (SGM), face distinctive healthcare transition challenges. SGM often navigate a complex intersection of identities, experiences, and stressors that can contribute to mental health disparities. However, they often lack access to appropriate support and resources tailored to their needs, which can result in increased psychological distress. Drop-in centers are effective mental health interventions for marginalized communities. Therefore, we conducted a study to explore the healthcare access experiences and mental health outcomes of young adult SGM compared to their non-SGM counterparts.

Methods: We surveyed 151 young adults aged 18-25 who …

Unique Root Anatomy Of Mandibular Second Premolars: Clinical Strategies For Effective Disinfection And Preservation Of Dentine Structure In Root Canal Treatment-A Case Report, Ji Wook Jeong, Erika Silguero Gonzalez, Scott R Makins, Timothy Kirkpatrick Jan 2024

Unique Root Anatomy Of Mandibular Second Premolars: Clinical Strategies For Effective Disinfection And Preservation Of Dentine Structure In Root Canal Treatment-A Case Report, Ji Wook Jeong, Erika Silguero Gonzalez, Scott R Makins, Timothy Kirkpatrick

Faculty, Staff and Student Publications

It is difficult to predict the outcomes of non-surgical root canal treatment (NSRCT) for mandibular second premolars with multiple root canals. In these teeth, the complicated anatomy with fin(s), or a C-shape, and possible secondary canal(s) varies unpredictably. The morphology of the root canals provides shelters for bacteria to remain, regrow, and form biofilms despite the endodontic treatment. Moreover, the prevalence of mandibular second premolars with multiple canals is extremely infrequent. Therefore, the clinical management of NSRCT in such cases is not sufficiently reported. This case report introduces two cases of NSRCT for mandibular second premolars with a radicular groove …

Synergistic Effects Of Antimicrobial Components Of The Human-Derived Composite Amnion-Chorion Membrane On Bacterial Growth, Alexandra Su Brummerhop, Chun-Teh Lee, Robin Weltman, Gena D Tribble, Ransome Van Der Hoeven, Yulun Chiu, Jianming Hong, Bing-Yan Wang

Faculty, Staff and Student Publications

Introduction: The human-derived amnion-chorion membrane (ACM) has endogenous antimicrobial properties, which are important for preventing the colonization and survival of oral bacteria on exposed membranes. This project aimed to decipher the underlying mechanism by identifying the components of ACM that confer antibacterial properties. In addition, the antimicrobial efficacy of these identified components on oral bacteria was assessed.

Methods: Four antimicrobial proteins, histone H2A/H2B, cathelicidin LL-37, lactoferrin, and lysozyme, were identified via mass spectrometry in ACM. These proteins were then assessed for their efficacy in killing Streptococcus gordonii Challis. Log-phased bacterial cells were cultured with the commercially available proteins that were …

BACKGROUND: Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort.

METHODS: This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. …


Racial And Ethnic Differences In Infant Survival For Hydrocephaly-Texas, 1999–2017, Munir Ahmed, Charles Shumate, Heidi Bojes, Ketki Patel, A J Agopian, Mark Canfield Jan 2024

Racial And Ethnic Differences In Infant Survival For Hydrocephaly-Texas, 1999–2017, Munir Ahmed, Charles Shumate, Heidi Bojes, Ketki Patel, A J Agopian, Mark Canfield

Faculty, Staff and Student Publications

Background: Congenital hydrocephaly, an abnormal accumulation of fluid within the ventricular spaces at birth, can cause disability or death if untreated. Limited information is available about survival of infants born with hydrocephaly in Texas. Therefore, the purpose of the study was to calculate survival estimates among infants born with hydrocephaly without spina bifida in Texas.

Methods: A cohort of live-born infants delivered during 1999-2017 with congenital hydrocephaly without spina bifida was identified from the Texas Birth Defects Registry. Deaths within 1 year of delivery were identified using vital and medical records. One-year infant survival estimates were generated for multiple descriptive …


Factors Associated With Infant Sex And Preterm Birth Status For Selected Birth Defects From The National Birth Defects Prevention Study, 1997–2011, Eva M Williford, Wei Yang, Meredith M Howley, Chen Ma, Ronnie T Collins, Kari A Weber, Dominique Heinke, Julie M Petersen, A J Agopian, Natalie P Archer, Andrew F Olshan, Lindsay A Williams, Marilyn L Browne, Gary M Shaw Jan 2024

Faculty, Staff and Student Publications

Background: Birth defects and preterm birth co-occur, with some overlapping risk factors. Many birth defects and preterm births tend to have a male preponderance. We explored potential risk factors impacting sex and preterm (< 37 weeks of gestation) birth differences among infants with selected birth defects delivered from 1997 to 2011 using data from the National Birth Defects Prevention Study (NBDPS).

Methods: The NBDPS was a large multisite, population-based case-control study. Using random forests, we identified important predictors of male preterm, female preterm, and male term, each compared with female term births for each birth defect. Using logistic regression, we estimated odds ratios for associations between important predictors and sex-preterm birth status by birth defect.

Results: We examined 11,379 infants with nine specific birth defects. The top …


Reimagining Youngblood's Bad Faith Requirement: Safeguarding Criminal Defendants' Due Process Rights Through A Burden-Shifting Framework, Rita Elfarissi Jan 2024

Reimagining Youngblood's Bad Faith Requirement: Safeguarding Criminal Defendants' Due Process Rights Through A Burden-Shifting Framework, Rita Elfarissi

Michigan Law Review

Criminal defendants face an uphill battle when attempting to prove that the government’s loss or destruction of evidence that could have played a significant role in their defense deprived them of their constitutional due process rights. To make this showing, the defendant must prove that the government lost or destroyed the evidence in bad faith. This requirement is problematic because direct evidence illustrating the subjective intent of the government officials who lost or destroyed the evidence is unlikely to exist, and in the off chance it does, the prosecution is unlikely to freely hand it over to the defendant. Thus, …

Nonlinear Changes In Facial Affect And Posttraumatic Growth: Assessment Of Ecological Momentary Assessment Video Data, Aaron M. Harwell, David Pincus, Bernard P. Ricca, Emmeline Taylor, Charles C. Benight

Psychology Faculty Articles and Research

Posttraumatic Growth (PTG), characterized by newfound meaning, perspective, and purpose for trauma survivors, remains enigmatic in its nature. This state is thought to arise from the dynamic interplay of biopsychosocial factors; however, the nature of this interplay is unclear. This study aimed to investigate the intricate relationship between PTG and facial affect dynamics, shedding light on the complex interplay of biopsychosocial factors that underpin this transformative process. We conducted a comprehensive investigation involving 19 wildfire survivors who provided daily self-reported PTG ratings alongside smartphone videos analyzed using Automated Facial Affect Recognition (AFAR) software. Our findings revealed compelling evidence of self-organization …


El Pequeño Riego De México: Puebla, Morelos, Y Baja California Sur, José A. Rivera Ph.D. Jan 2024

El Pequeño Riego De México: Puebla, Morelos, Y Baja California Sur, José A. Rivera Ph.D.

Faculty Publications

Small to medium-sized irrigation systems in México are characterized in the literature as El Pequeño Riego. Some systems can be compared to those in northern New Mexico and southern Colorado, while others are significantly larger and more complex. Regardless of irrigated acres or hectáreas, however, there are many elements that are commonly shared across these regions. Firstly, the irrigation works are based on the use of acequias dug from the earth that need to be maintained and cleaned season to season. The terms canals and acequias are interchangeable. Secondly, the irrigators themselves, whether called parciantes or regantes, take …

Associations Between Positive Affect And Physical Activity From Young Adulthood To Midlife: A 25-Year Prospective Study, Farah Qureshi, Laura D. Kubzansky, Ying Chen, Jackie Soo, Eric S. Kim, Donald Lloyd-Jones, Julia K. Boehm

Psychology Faculty Articles and Research

Objective: Positive affect may influence health by promoting physical activity, but evidence evaluating this association is mostly cross-sectional and cannot discern directionality. This study used a counterfactual-based framework to estimate the causal effect of positive affect on physical activity patterns over 25 years, accounting for potential reverse associations. Method: Data were from 3,352 participants in the Coronary Artery Risk Development in Young Adults study. Repeated assessments of positive affect and physical activity were collected from 1990 to 2016. Longitudinal associations were evaluated in two ways: (a) using baseline positive affect in traditional linear mixed models that accounted for reverse causal …


Justice Via Chat? How Litigants’ Preferences And Attorneys’ Recommendations Influence The Choice To Use Online Dispute Resolution, Andrea C. F. Wolfs, Donna Shestowsky Jan 2024

Justice Via Chat? How Litigants’ Preferences And Attorneys’ Recommendations Influence The Choice To Use Online Dispute Resolution, Andrea C. F. Wolfs, Donna Shestowsky

Psychology Faculty Articles and Research

There is a significant need for empirical evidence concerning how litigants compare and choose between various modalities of online dispute resolution (ODR) and traditional in-person mediation for resolving legal disputes. To fill this need, we examined three potentially relevant psychological factors: (a) baseline attitudes toward in-person, video, and text-based mediation; (b) past communication style used by litigants; and (c) expert advice via attorney recommendations. We utilized a 2 × 3 × 3 design with communication style as a between-subjects variable, mediation modality as a within-subjects variable, and attorney recommendation randomized as either aligning with or differing from the participant’s baseline …


Counting Is Hard! A Theory Of Doctrinal Expansion, Kip Hustace Jan 2024

Counting Is Hard! A Theory Of Doctrinal Expansion, Kip Hustace

Faculty Articles

We conventionally see pleading as liberalized, with leeway for inconsistent claims and expansive choice among theories of relief, or counts. Yet procedure scholars have shown how heightened pleading post-Twiqbal constricts liberality, turning us back toward 19th Century fact-intensive code pleading. This Article theorizes a further constriction: proliferating and ossifying counts. While affording pleading latitude, doctrinal expansion forces hard strategy decisions and represents an inversion of the maxim that procedure shapes substance. Expansion increases system complexity, making localized strategy and discretion more impactful and amplifying opportunities for juridical manipulation. The result: doctrines complexifying toward a tipping point, beyond which we make …

Equity And Inclusion In Honors: A Case Study Of Admissions Changes, Andrew Dilts, Trevor Zink

Management Faculty Works

Creative levers for change often emerge in times of institutional uncertainty. As higher education continues to confront institutional racism, honors programs can exercise their power to increase diversity and educational outcomes for excluded and marginalized students, as well as influence related university-level policy. This case study chronicles dramatic changes to admissions policies and programmatic offerings in honors between 2020-2023. Changes in admissions practices markedly diversified the student body, moving it from a 60% white population to 60% minority population in just three years. Conversations around race and racism were initiated, inculcating a culture of inclusion rather than elitist exceptionalism. As …


Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França Jan 2024

Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França

Faculty, Staff and Student Publications

Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically-sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key components of the extracellular matrix (ECM) where they can serve as mechanosensors in mechanosensitive tissues including bone, cartilage, tendon, blood vessels and soft organs. The mechanical properties of these tissues depend on the presence and function of PGs, which play important roles in tissue elasticity, osmolarity and pressure sensing, and response to physical activity. Tissue …


Revocation At The Founding, Jacob Schuman Jan 2024

Revocation At The Founding, Jacob Schuman

Michigan Law Review

The Supreme Court is divided over the constitutional law of community supervision. The justices disagree about the nature of a defendant’s liberty under supervision, the rights that apply when the government punishes violations, and the relationship between parole, probation, and supervised release. These divisions came to a head in 2019’s United States v. Haymond, where the justices split 4–1–4 on whether the right to a jury trial applies to revocation of supervised release. Their opinions focused on the original understanding of the jury right at the time the Constitution was ratified.

This Article aims to settle the debate over …


Scrutinizing The Bathroom Binary: Equal Protection Theories For Nonbinary Students, Annie Schuver Jan 2024

Scrutinizing The Bathroom Binary: Equal Protection Theories For Nonbinary Students, Annie Schuver

Michigan Law Review

Over the past decade, transgender students have challenged discriminatory school bathroom policies under the Equal Protection Clause with varying success. But another group of students, facing similar discrimination, has yet to see its day in court. Like their transgender peers, nonbinary students often lack access to gender-appropriate restrooms at school. Many K–12 schools offer only “boys” and “girls” restrooms, ignoring the needs of students who identify as neither boys nor girls, as both of those genders, or as something else entirely. Forced to use sex-segregated bathrooms (or no bathroom at all), nonbinary students suffer adverse health, safety, and educational outcomes. …

Evaluation Of Silk Fibroin And Hylauronic Acid As Otic Drug Delivery System Additives; Investigation Of Silk Fibroins Responses To Enviromental Stimulii, Kolton Charles Sandau

Graduate Student Theses, Dissertations, & Professional Papers

The Serban lab has previously developed and reported on a single application drug delivery system for the treatment of otitis externa. Otitis externa also known as outer ear infections is a very common ailment that impacts large portions of both human and domestic animal populations. Typical treatment for otitis externa typically requires an extended dosing regimen over several days that is inconvenient and can lead to poor clinical outcomes due to poor patient compliance. Our delivery system employs a thixotropic gel to deliver a steady dose of medication over the duration of the infection.

Here we evaluated the reproducibility and …


Density Anomaly Leads To Rift Initiation: Quantifying Active Rifting And Comparison To The East African Rift Zone, Chloe Boucher Jan 2024

Density Anomaly Leads To Rift Initiation: Quantifying Active Rifting And Comparison To The East African Rift Zone, Chloe Boucher

Graduate Student Theses, Dissertations, & Professional Papers

Active rifting, elastic failure in the lithosphere from rising density anomalies in the mantle, is fundamental to the Wilson Cycle which describes the cycle of tectonic plates. Active rift zones are common in the oceanic lithosphere but are less common in the thicker continental lithosphere. The current largest active continental rift zone is the East African Rift Zone (EARZ). Although active rifting is fundamental to plate tectonic theory, the mechanics and parameters needed for a density anomaly to initiate a rift have not been undertaken. This model aims to solve the problem of a density anomaly initiating a continental rift …
