School Psychologists As Advocates: Addressing Microaggressions Targeting Students In Schools, Brea M. Banks, Lourdes D. Concepcion-Cabas, Farhia A. Osman, Kendell Kelly

Faculty Publications – Psychology

The aim of this conceptual paper surrounds a discussion of school psychologists’ role as advocates who can combat the prevalence of microaggressions in schools. The authors first define microaggressions in the context of Critical Race Theory and discuss the negative impact these transgressions have on students. Advocacy is a foundational role of school psychologists, and combatting microaggressions is one way school psychologists can engage in such efforts. Given the goal of this special issues is to highlight how social justice advocacy can address critical issues in school psychology, we use the NASP Practice Model as a framework to describe how …

From Nesting To Emergence: Environmental Drivers Of Hatchling Success In Blanding’S Turtles And Implications For Management In Southeast Michigan, Morgan Boyer

Master's Theses and Doctoral Dissertations

Blanding’s turtles (Emydoidea blandingii) are long-lived turtles whose populations are highly sensitive to juvenile recruitment. We used intensive nest monitoring, microclimate logging, soil measurements, and local weather data at two Southeast Michigan sites to quantify how nest placement, incubation environments, and substrate conditions influence emergence success and hatchling condition. Nesting females were morphologically similar in size and produced average clutch sizes for the species (8 ± 2 eggs). Nest sites were found on relatively open, disturbed uplands with sandier soil substrates. Emergence success was generally high (≈ 70-80%) in nests protected from predation. Sandy loam had the highest success rates …

Examining Knowledge And Comfort Levels Of Nursing Students In Providing Sexual Health Education, Deanna M. Gower

Master's Theses and Doctoral Dissertations

Sex education has been a part of the education in the United States for over 100 years. Nursing education is focused on educating nursing students in a comprehensive fashion that develops a safe and competent nurse. Due to the substantial scope of content required in nursing programs, sexual health topics can be pushed aside. This may result in gaps in sexual health knowledge and comfort for nursing students as they may be inadequately prepared to competently address patients’ sexual health needs in clinical practice. The purpose of this cross-sectional descriptive study is to examine nursing students knowledge and comfort levels …

Social Exclusion, Social Support, And Trauma, Eric D. Wesselmann

Faculty Publications – Psychology

Humans have an inherent need to forge stable and quality social connections. One key benefit of having social connections is obtaining social support for navigating traumatic or otherwise stressful events. Ostracism (i.e. being both ignored and excluded, Williams, 2009) and other forms of social exclusion rob individuals of the opportunity to receive social support and likely contribute to stress-related mental health concerns. My colleagues and I tested this premise in different stress-related contexts, ranging from college students struggling with potentially stigmatizing secrets to community members who have experienced various types of traumatic incidents (e.g., miscarriage, military combat). We examined the …

Fishing For Father Relationships: Motivations, Successes, And Barriers To Participating In A Community-Based Program, Jordan A. Arellanes, Kyle Miller, Travis Hicks, Ryan J.S. Liew, Earl Kloppmann

Faculty Publications – Psychology

Fathers who participate in community programs experience a range of positive outcomes, including improved relationships with their children. However, many community programs struggle to gain fathers’ attendance at local events. To counteract this, we utilized Community-Based Action Research in collaboration with local and state agencies to develop a father-specific community program that capitalized on the traditionally masculine parenting activity of fishing. The program educated families on the basics of fishing and then provided them with all the necessary materials. Over the course of three years of data collection, 48 fathers participated in interviews, designed to gain a deeper understanding of …

The Effects Of A Work-Strengths Affirmation Intervention On Death Anxiety, Begüm Orhan, Margaret M. Nauta

Faculty Publications – Psychology

Meaning Management Theory suggests that engaging with meaning-related resources helps individuals constructively regulate consciously experienced death anxiety. Consistent with that theory, we tested whether a single-session, online work-strengths affirmation intervention reduces college students’ (N = 201) death anxiety. Participants completed baseline measures of death anxiety, meaning in life, and self-esteem. One week later, they were randomly assigned to complete either a work-related strengths reflection exercise or a neutral writing task. We assessed outcomes immediately post-intervention and two weeks later. The intervention did not significantly reduce death anxiety in the full sample. Exploratory analyses showed small, immediate reductions among participants …

Shades Of Stress: Colorism As Minority Stress For Women Of Color, Caitlin M. Mercier, Brea M. Banks, Lourdes D. Concepción Cabán, Michelle Duong

Faculty Publications – Psychology

Women of color often endure indignities shaped by colorism and skin tone discrimination, pressuring them to adhere to racialized beauty ideals (i.e., lighter skin). In response, some women of color may internalize these standards (i.e., through internalized coping and racial self-hatred) which can foster psychological distress. Yet, these associations remain underexplored. Using minority stress theory, in our cross-sectional study we collected online survey data to examine whether internalization and racial self-hatred explained the indirect link between colorist microaggressions and psychological distress among 121 women of color at a Midwestern US historically white institution. Using path analysis, we found support for …

Methods: This study included 175 post-RP patients receiving IAD, with a median follow-up of 44.77 months [interquartile range (IQR), 31.87–69.50 months] post-androgen deprivation therapy (ADT). The IAD protocol used a PSA threshold of 0.2 ng/mL to define progression …

Therapeutic Landscape Of Early Symptomatic Alzheimer's Disease Translated Into Everyday Practice For Geriatric Providers., Melissa J Bailey-Taylor, Paula Morrow, James Hendrix, Katherine E. Galluzzi, Golnosh Sharafsaleh

PCOM Scholarly Works

Alzheimer's disease (AD) accounts for 60-80% of all dementia cases. Recent advances in diagnostic biomarkers of early symptomatic AD (ie, mild cognitive impairment and mild dementia due to AD) and amyloid-targeting therapies (ATTs) have the potential to improve outcomes for patients with AD. Two ATTs (donanemab and lecanemab) are currently approved and available for use in the US. Both ATTs can slow disease progression as well as cognitive and functional decline in patients with early symptomatic AD. Treatment with ATTs is associated with specific safety concerns such as amyloid-related imaging abnormalities. Therefore, the benefit versus risk profile needs to be …

Effect Of Garnet Incorporation On The Functional Properties Of Sunscreens, Parinya Chakartnarodom, Kanyarat Munmani, Sureerat Polsilapa, Duangrudee Chaysuwan, Wichit Prakaypan, Passakorn Sonprasarn, Edward Laitila, Nuntaporn Kongkajun

Journal of Metals, Materials and Minerals

Garnet, a silicate mineral, was investigated as a replacement for the TiO2-based compound in sunscreen formulations. Samples containing garnet were evaluated for color shade, viscosity, sun protection factor (SPF), and water resistance. Substituting the TiO2-based compound with garnet reduced both viscosity and SPF but markedly enhanced water resistance. This improvement is attributed to the physical reinforcement provided by garnet particles, which strengthen the sunscreen film and reduce wash-off under water exposure. Garnet incorporation also altered the product’s appearance from white to a darker brownish-beige tone, improving visual compatibility with a wider range of skin tones.

Anthocyanins are valuable dietary elements with biological functions and health-promoting effects. However, there are technological barriers to their use in the food industry, primarily due to their poor stability and susceptibility to environmental factors, such as oxygen, temperature, pH, and light, which can significantly affect the physicochemical characteristics of the final food products. In this study, the microencapsulation of an anthocyanin extract from sohiong fruits was performed using a laminar jet flow vibration nozzle, with calcium chloride as a hardening agent and sodium alginate as a polymer. To produce calcium-alginate microbeads with a high anthocyanin content and favourable morphological characteristics, …

Synergistic Ph-Shift And Heat Treatment For The Recovery Of Protein Isolates From Ham Processing Brine: Evaluation Of Protein Ingredient Quality, Structure, And Functional Properties, Anim Ujong, Carlos Álvarez, Brijesh K. Tiwari, Shay Hannon, Uma Tiwari

Research Outputs: 2025-Present

Ham processing generates significant volumes of brine, a saline wastewater with untapped potential. This study compared three protein recovery methods: direct centrifugation, moderate heat treatment (75 °C), and a combined pH-shift-mild heat (PSMH) approach (65 °C). Both the PSMH method and moderate heat precipitation produced protein concentrates with the highest initial protein contents (62.15%–62.81%), which increased to 91.65%–95.59% purity after desalting, with NaCl levels reduced to <1.5%. Amino acid analysis revealed that PSMH-derived proteins had the highest total amino acid content (96.58 g/100 g). Sodium dodecyl sulphate-polyacrylamide gel electrophoresis confirmed improved recovery of muscle proteins, while Fourier transform infrared spectroscopy indicated that moderate heat treatment reduced the α-helix/β-sheet ratio. Proteins recovered using PSMH exhibited the highest water and fat binding capacities and maintained solubility across a broad pH range. They also exhibited strong foaming ability, although they showed slightly lower foam stability than proteins recovered by other methods, and they demonstrated emulsifying properties that were optimal under mildly alkaline conditions. Overall, PSMH presents a sustainable and efficient strategy for recovering functional proteins from ham brine for use in food and feed applications.

Research Outputs: 2025-Present

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder marked by persistent memory impairment and complex molecular and cellular pathological changes in the brain. Current treatments, including acetylcholinesterase inhibitors and memantine, only help with symptoms for a short time and do not stop the disease from getting worse. This is mainly because these drugs do not reach the brain well and are quickly removed from the body. The blood–brain barrier (BBB) restricts the entry of most drugs into the central nervous system; therefore, new methods of drug delivery are needed. Nanotechnology-based drug delivery systems (NTDDS) are widely studied as a potential …
