Investigation Of The Combined Effects Of Temperature And Nutrients On Chlorophyll-A Concentration In The Tigris River, Baghdad, Yaqeen Ameen, Jinan S. Al-Hassany

Baghdad Science Journal

Rivers are exposed to global warming and eutrophication, which in turn affect phytoplankton biomass in rivers. This study investigates the changes in Chl-a concentration, an indicator of phytoplankton biomass. A microcosm experiment was conducted, with water sampling from the Tigris River in Baghdad during the wet season. Temperature increase was based on raising the temperature by 3 °C higher than the ambient temperature, while nutrient enrichment was based on the mean values of soluble reactive NO_3^-1 and PO_4^-3 verified in the Tigris River. Variations in Chl-a concentration are associated with changes in WT and nutrient enrichment; …

Baghdad Science Journal

Several studies have reported the potential antiviral activity of Artemisia species, which is related mainly to their flavonoid constituents. Transmembrane serine protease 2 (TMPRSS2) and angiotensin-converting enzyme 2 (ACE2) are critical SARS-CoV-2 entry factors. In this study, the phytochemical composition and modulatory effects of Artemisia herba-alba leaf extract on the gene expression of ACE2 and TMPRSS2 were investigated. To identify the flavonoid profile, HPLC was used. Cytotoxicity was estimated in A549 carcinoma and HDFn fibroblasts using an MTT assay (IC₅₀ = 114.8 μg/mL). The real-time PCR results revealed significant upregulation of TMPRSS2 gene expression (2.4-fold, p ≤ 0.01; …

Neutrophil Gelatinase-Associated Lipocalin (Ngal) And Urine Albumin-To-Creatinine Ratio (Uacr) In Patients With Chronic Kidney Disease: A Cross-Sectional Study, Nurul Annisa Yunus, Puspa Wardhani, Yessy Puspitasari, Satriyo Dwi Suryantoro, Zulfian Armah

Folia Medica Indonesiana

Chronic kidney disease (CKD) remains a major global health burden with an increasing prevalence and a substantial risk of progression to end-stage renal disease. Urine albumin-to-creatinine ratio (uACR) is widely used as a conventional biomarker reflecting glomerular injury in CKD, whereas neutrophil gelatinase-associated lipocalin (NGAL) has been proposed as a biomarker associated with tubular injury and inflammatory processes. This study aimed to determine the correlation between serum NGAL levels and uACR in patients with CKD. The authors conducted an analytical observational study with a cross-sectional design on 32 CKD patients at Universitas Airlangga Hospital. Serum NGAL levels were measured using …

Histopathological Evidence Of Irreversible Testicular Injury And Spermatogenesis Disruption In A Continuous Scrotal Hyperthermia- Induced Azoospermia Rat Model, Ageng Brahmadhi, Norina Agatri, Andi Muh. Maulana, Rahmadita Cahya Maharani, Dyanti Arisa Nurrizki

Folia Medica Indonesiana

Non-obstructive azoospermia (NOA) is a cause of male infertility characterized by impaired spermatogenesis. NOA remains a challenge for both research and treatment development. Reliable animal models are essential for better understanding its pathophysiology and evaluating therapeutic approaches. Scrotal hyperthermia induction is a cost-effective and technically feasible method for inducing NOA. However, the impact of different exposure patterns remains unsolved. In this study, a total of 30 adult male Rattus norvegicus were randomly assigned to control, discontinuous hyperthermia (every other day), and continuous hyperthermia (daily) groups. This study applied the heat exposure by immersing the scrotum in a 45°C water bath …

Main-Chain Ion-Pair Polybenzimidazole Membranes Enabling Reduced-Temperature Ht-Pemfc Operation (Down To 120°C), Brian C. Benicewicz, Huina Lin

Faculty Publications

Proton exchange membrane (PEM) fuel cells are promising for clean and efficient energy conversion across diverse applications. High-temperature PEM fuel cells (HT-PEMFCs) using phosphoric acid (PA)-doped polybenzimidazole (PBI) can operate up to 200°C, but at lower temperatures, water-induced PA loss often leads to performance degradation and reduced durability. In this work, we present a new class of main-chain ion-pair PBI membranes by integrating the imidazolium-biphosphate ion-pair units directly into the PBI backbone. This design results in membranes with high acid content, stronger acid-polymer interactions and stabilized acid retention. In single-cell tests, the Im+-PBI15-3 wt.% exhibits peak power densities of 0.79 …

Freedom In The Press: Black Print Culture And Antislavery Activism In The United States, 1772-1857, Bernard T. Baze

Doctoral Dissertations and Projects

Nineteenth century African American journalists employed the press as a political, legal, and moral instrument to challenge the legitimacy of the institution of American slavery and advocate for universal emancipation. Through an analysis of the Black press, including Freedom’s Journal, Colored American, North Star, Frederick Douglass’ Paper, Provincial Freeman, and the Christian Recorder, the study highlights the agency of Black abolitionists in shaping antislavery public discourse. It contends that these writers advanced a multifaceted antislavery strategy rooted in moral suasion, constitutional argumentation, legal denunciations, and religious advocacy. Through these efforts, they revealed the contradictions between slaveholding and the nation’s professed …

The study investigated whether differences in EQ exist between students with and without LDs and whether age influences EQ development. The 102 participants included male and female students in grades 6-12, ages 11-18, attending a Christ-centered college preparatory school. Students completed a 30-question EQ questionnaire during the researcher’s class time, and online surveys were coded to identify …

Children With Cerebellar Malformations And Co-Occurring Autism: A Phenomenological Study Exploring Challenges Faced With The Dual Diagnosis Process, Service Acquisition, And Psychosocial Impacts, Ladeana W. Gambill

Doctoral Dissertations and Projects

Parents of children who have been diagnosed with cerebellar malformations, such as Dandy-Walker Malformation, often face confusion and frustration as they are given uncertain prognoses about their child’s future. The uncertainty is further compounded when there are concerns for autism spectrum disorder (ASD), and testing is sought, with conflicting answers on whether their child has autism or not. Acquisition of autism-specialty services may be delayed if a diagnosis of autism is not received in a timely manner. The purpose of this interpretive phenomenological study was to understand the lived experiences and challenges faced by parents of children with cerebellar malformations …

Strengthening The Mind: Evaluating Emotional Intelligence As A Tool To Combat Anxiety In Youth Soccer, John P. Hill

Doctoral Dissertations and Projects

Competitive anxiety is a significant challenge for adolescent soccer players, contributing to psychological distress and early sport withdrawal, and approximately 70% of youth athletes quit organized sport by age 14. Emotional intelligence, the capacity to recognize, understand, and regulate emotions, represents a promising and trainable intervention target, yet few studies have examined structured EI programs with youth soccer populations using rigorous experimental designs that include a parallel control group. This quantitative intervention study examined the effect of an emotional intelligence intervention on competitive anxiety among youth soccer players, including whether individual emotional profiles and gender moderated outcomes.

Employee absenteeism is detrimental to organizational effectiveness and efficiency. Workers’ compensation claims are a potential liability to government organizations, as claims filed by employees for work-related injuries or illnesses may impact insurance premiums based on the number and severity of claims filed. Identifying and implementing solutions to mitigate the effects of absenteeism and workers’ compensation claims are critical to organizational sustainability. This quantitative study seeks to determine if workplace health and wellness programs decrease absenteeism and reduce workers’ compensation claims levels among public sector employees. Post-positivism and functionalism provide this study with a theoretical underpinning. The variables of interest were …

How Are Depression And Anxiety In Biracial Black–White Adults Related To Monoracial Familial Connectedness Throughout Life?, Cary M. Steffey

Doctoral Dissertations and Projects

The multiracial population is the fastest-growing minority group in the United States, yet their mental health and familial experiences are insufficiently studied. Due to their complex racial backgrounds, unique life experiences, and diverse social connections, multiracial individuals endure mental health issues that differ from those of many other populations, including their family relationships. Some of these differences include how these relationships affect life experiences and mental health status. This quantitative study examined psychological well-being among multiracial individuals, with a focus on relationships with monoracial family members. This study hypothesized that greater familial support predicts improved mental health outcomes. The study …

Caregiver Depression And Psychological Distress As Predictors Of Substantiated Maltreatment In Nscaw Ii (Wave 2 Cps Sample): A Quantitative Archival Study, Gloria Forotan

Doctoral Dissertations and Projects

This quantitative archival analysis examined whether caregiver mental health is associated with child maltreatment outcomes through CPS involvement, using the National Survey of Child and Adolescent Well-Being II (NSCAW II), Wave 2. Child maltreatment remains a persistent public health concern with long-term effects on children's emotional, psychological, and physical development. Although caregiver mental health is consistently identified as a significant risk factor for maltreatment, few studies have utilized nationally representative child welfare data with standardized measures to test these associations.

Caregiver mental health variables were operationalized using NSCAW II indicators of major depression and depressive symptoms (DP2), psychological distress (K6 …

The Impact A Lack Of Racial/Ethnic Diversity Has On Spiritual Formation And The Key Actions Necessary For Resolution, Kimberly Janelle Baker

Doctoral Dissertations and Projects

The problem this research addresses is that New Community Church, a local church ministry, lacks a racially/ethnically rich and diverse spiritual formation experience. A lack of racial/ethnic diversity within churches nationwide is a pervasive issue. While some churches are not more diverse due to location, there are many, including the specific church chosen to be included as part of the problem statement, that are located in diverse communities but still do not adequately reflect the racial/ethnic make-up of their respective communities.

Martin Luther King Jr., once said that “It is appalling that the most segregated hour of Christian America is …

The Role Of Resilient/Protective Factors In Adolescence As A Buffer Among Adults With A History Of Childhood Trauma And Symptoms Of Depression In Adults, Michaela L. Fox

Doctoral Dissertations and Projects

Childhood trauma includes adverse experiences during early development, such as physical, emotional, sexual, or verbal abuse and neglect, and is associated with negative outcomes, including depressive symptoms in adulthood. This study examined whether protective factors during adolescence are related to adult depressive symptoms among individuals with a history of childhood trauma. Two research questions guided the study: (a) Is there a difference in adult depressive symptoms between individuals with minimal versus significant protective factors during adolescence, and (b) Is there a statistically significant relationship between adolescent spirituality and adult depressive symptoms? A quantitative, correlational design was used with self-report surveys …

Mental Toughness In Motherhood: A Qualitative Phenomenological Approach To Advancing Developmental Understanding, Mary Kauffman

Doctoral Dissertations and Projects

This qualitative phenomenological study explored how mothers define, experience, and describe mental toughness within the developmental context of motherhood. Mental toughness has been extensively examined in performance-based domains such as sports, education, business and military settings. Limited research has investigated how this construct appears or manifests in caregiving roles. Understanding mental toughness in motherhood may inform how mothers are supported psychologically and contribute to future frameworks, interventions, and systems designed to strengthen maternal well-being, adaptation, and long-term functioning. Guided by Bandura’s self-efficacy theory, which focuses on the perceived ability of individuals to navigate adversity, this study examined mental toughness as …

From Crip Time To Care Time: How Library Administrators Can Support Professional Development Of Disabled Employees, Leah T. Dudak, Rhys Dreeszen Bowman Dr.

School of Information Studies - Post-doc and Student Scholarship

Building on our 2025 In the Library with the Lead Pipe article "Cripping Conferences", this piece moves from naming the problem to offering solutions to library administrators. Disabled library workers face significant barriers to professional development, including the financial cost of attendance, the physical and mental toll of navigating inaccessible spaces, and the conflict between crip time and the neoliberal clock time that governs academic and library culture. While accommodations are needed, they are not enough; we need to interrogate the systems that exclude disabled employees. Written by two disabled LIS scholars, this piece offers library administrators practical guidance, from …

Past Present, & Future: Bushwick Inlet Redevelopment, Aaryan Nair

Publications and Research

This report examines how ecosystem structure, hydrology, and material flows in Williamsburg, Brooklyn have changed from pre-colonial conditions to the present and how they are expected to evolve under future climate change. Prior to European colonization, the landscape functioned as a forest–wetland mosaic with high infiltration capacity, slow water movement, and strong nutrient retention. These conditions supported stable aquatic ecosystems and minimized pollutant transport to the East River.

Modern urbanization has fundamentally altered this system. Impervious surfaces and engineered drainage systems have shifted hydrology from infiltration-dominated to runoff-dominated pathways, producing rapid “flashy” flows and reducing water residence time.

A Qualitative Study Of Gratitude Practice Among Won Buddhist Older Adults And Implications For Gerontological Social Work, Sungsim Lee

Dissertations

Although gratitude has been widely studied in social science, existing scholarship has largely relied on Western worldviews and quantitative research frameworks, limiting understanding of lived gratitude experiences within diverse spiritual and cultural contexts, including Eastern spiritual traditions. In Won Buddhism, originating in South Korea, gratitude holds a central place in spiritual life and is understood as an essential practice. This qualitative study explores the views of Won Buddhist older adult practitioners regarding their experiences, benefits, and challenges of engaging in spiritually grounded gratitude practice. Semi-structured interviews were conducted with 23 practitioners aged 65 and older from English-speaking Won Buddhist communities. …

Dissecting The Discourse: Colin Kaepernick's National Anthem Protest And Conservative Media As Competing Racial Projects, Travis Moody

Master's Theses

This thesis examines the media portrayal of Colin Kaepernick’s protest against police brutality and racial injustice during the National Anthem in the 2016 National Football League (NFL) season. Using content analysis, I analyze why Colin Kaepernick protested in his own words and how conservative media outlets such as Fox News rearticulated and criticized his social justice stance as an unpatriotic denigration of the American flag and Star-Spangled Banner. As I further argue, social movements such as #BlackLivesMatter and the Colin Kaepernick-inspired “Take a Knee” movement represent a political project to inform racial discourse regarding racial injustice in the United States. …

Responsive Rigor And Strategic Care: Faculty Praxis For Holistic Student Success In The Community College, Jennifer Elizabeth Kelley

Dissertations

This qualitative study examines how community college faculty conceptualize, communicate, and enact academic rigor and care in their teaching practice. While post-pandemic debates have positioned rigor and care as opposing forces—evident in the "Rigor Wars" that framed care as performative laxity and rigor as gatekeeping—community college faculty successfully integrate these practices to support holistic student success. This research addresses critical gaps in higher education scholarship, which has studied rigor and care separately, focused primarily on four-year institutions, and overlooked faculty perspectives on how integration occurs in practice. Drawing on a single-case study of 38 faculty members at a large Midwestern …

"An Unusual Experiment:" The Women Of The Oss, Adaline Mae Brenning

Masters Theses

As the United States entered World War II, President Franklin D. Roosevelt established America's first centralized intelligence organization under the leadership of Major General William J. Donovan in June 1942. The Office of Strategic Services marked the beginning of an established American intelligence community, but it also served as an entryway for women to join the war effort through intelligence work. Through the study of the recruitment, assessment, and training processes and women serving both domestically and abroad, it is possible to establish a more comprehensive view of the true scope of OSS operations during the war. Additionally, the stories …

Just Hillbillies: State Power, Private Militarism, Coal, And Constitutional Crisis In The West Virginia Treason Trials, 1919-1937, Ryan Gregory Fix

Masters Theses

In August 1921, roughly ten thousand armed coal miners marched toward Logan County, West Virginia, in the largest armed labor uprising in American history. When the fighting at Blair Mountain ended, the state prosecuted union leaders for treason against the state of West Virginia. This thesis examines that legal campaign of 1921–1923 and its long aftermath, arguing that the treason trials functioned less as a search for individual guilt than as an instrument for fixing the meaning of Blair Mountain before the miners could define it themselves. Where decades of gubernatorial proclamations and martial law had exposed the limits of …

In Search Of Whitman's "Real War": Soldier Recreations During The American Civil War, Rebecca C. Felton

Masters Theses

When most people think of the American Civil War, they recall the agonies and ecstasies of combat, envisioning the bombardment of Fort Sumter, the glorious folly of Pickett’s Charge, or the ravages of Sherman’s March to the Sea. What gets left out of the history books is what the common soldier experienced more than anything else: camp life. This study sheds renewed light on what the soldiers of the Union and Confederacy did to pass the time between battles. It focuses specifically on what they did for fun, addressing three categories of recreational activities: sports, music, and literature. It finds …
