New Orleans, Louisiana, faces profound environmental vulnerabilities arising from the convergence of industrial pollution, urban runoff, and climate change–driven weather events. This paper examines systemic challenges affecting water and air quality in the region, with particular focus on low-income and marginalized communities disproportionately burdened by environmental degradation. Drawing on educational and community-based monitoring initiatives at Xavier University of Louisiana and Southeastern Louisiana University, we highlight the integration of student learning with real-time data collection of contaminants such as fecal coliforms, heavy metals, hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). The aftermath of Hurricane Katrina revealed significant fecal contamination in sediment layers, …
Key Elements Of Mission-Based Urban Agriculture In The United States Aimed At Addressing The Social Determinants Of Health, Jordan Losavio
Key Elements Of Mission-Based Urban Agriculture In The United States Aimed At Addressing The Social Determinants Of Health, Jordan Losavio
LSU Doctoral Dissertations
Urban agriculture (UA) in the United States (U.S.) is increasingly positioned as a multi-domain strategy for addressing social determinants of health (SDOH), yet evidence is fragmented and often focused on participant outcomes rather than the organizational and environmental conditions that determine whether those benefits can be sustained, expanded, or maintained over time. This dissertation uses an exploratory sequential mixed-methods design to clarify (1) what SDOH outcomes are associated with UA in the peer-reviewed literature, (2) which internal and external factors leaders perceive as driving UA organizational success or failure, and (3) which factors predict comparative organizational functioning across a national …

Hybrid Diabetes Coaching Model: Integrating In-Person And Telemedicine Strategies To Improve Glycemic Outcomes, Sandis A. Mundackal
Hybrid Diabetes Coaching Model: Integrating In-Person And Telemedicine Strategies To Improve Glycemic Outcomes, Sandis A. Mundackal
Student Scholarly Projects
Practice Problem: In patients with type 2 diabetes, poor glycemic control among adults remains a significant challenge in primary care settings, particularly within federally qualified health centers (FQHCs) that serve underserved populations. At the FQHC practice site, patients were managed using standard care with quarterly follow- up visits, without a structured hybrid coaching approach. This inconsistency contributed to a high number of patients with hemoglobin A1c (HgbA1c) levels ≥ 9%, placing them at increased risk for diabetes-related complications.
PICOT Question: In adults with poorly controlled type 2 diabetes (HgbA1c ≥ 9%) (P), does monthly hybrid coaching delivered through in-person and/or …
The Case For Recognizing Informally Adopted Children As Heirs In Arkansas, Joel Gaffney
The Case For Recognizing Informally Adopted Children As Heirs In Arkansas, Joel Gaffney
Arkansas Law Notes
Americans are steadily moving away from the nuclear family towards an understanding of family less defined by shared DNA or last names. This is especially prominent in the way children are raised. More children are being born to single or unmarried parents, and a fair number of children are being raised by nonparents. Such nonparental caretaking can manifest as “informal adoption,” where there is no biological or legal parent-child relationship but there is a functional parent-child relationship. Certain areas of the law sometimes struggle to keep up with these changes in the meaning society assigns to “family.” Statutory probate law …

Analysis Of Novel Cannabis Products Labeled As Containing Thc-Jd, Kaelas R. Munger, Carlton C. B. Bone, Killian M. Anreise, Robert M. Strongin
Chemistry Faculty Publications and Presentations
Objective:
THC-JD (tetrahydrocannabioctyl) is a semi-synthetic cannabinoid with an eight-carbon C3 side chain, present in only trace amounts in hemp, requiring synthesis for commercial use. It has been promoted as potentially 19 times more potent than delta-9-THC, consistent with enhanced CB1 receptor affinities for cannabinoids with 7-8 carbon C3 side chains. While one peer-reviewed report identified THC-JD (tetrahydrocannabioctyl) in Japanese online products, an anecdotal report from the U.S. suggests mislabeling. Method: To inform regulatory efforts and consumer awareness and to address these discrepancies, this study chemically analyzed five U.S. commercial cannabis vape products marketed as containing THC-JD. Results: Utilizing GC-MS …

Challenging behaviors, including noncompliance, aggression, hyperactivity, and impulsivity, are common among individuals with Fragile X Syndrome (FXS) and Down Syndrome (DS). To identify treatment needs specific to these populations, we conducted focus groups with caregivers and educators and used their input to adapt an evidence-based caregiver training program originally designed for caregivers of autistic children (i.e., The Research Units in Behavioral Intervention; RUBI). We then completed a feasibility trial in which five families of children with FXS and four families of children with DS completed a nine-session caregiver training program targeting behavioral principles, syndrome-specific information, and visual supports tailored to …

The 1986 EDSA Revolution was a pivotal moment in Philippine history, where Filipinos united to oppose the tyranny under the dictatorship of former President Ferdinand Marcos Sr.. However, the country still faces long-term instabilities in its aftermath. Thus, by accounting for the facets contributing to the discourse of the general will, the paper examines EDSA through Jean-Jacques Rousseau’s theory to ascertain whether political rallies are compatible under a social contract—an agreement concerning individuals’ rights and responsibilities to stimulate respectful coexistence and law adherence. This paper argues that political rallies are compatible if they uphold the general will and when the …

This research aims to find a natural way to make cardboard more water-resistant, increasing its recyclability and lifespan by using banana peels (BP) and star apple leaves (SAL). The inspiration behind this study comes from commercial coatings that are made from synthetic chemicals, such as fluoropolymers and silicone, that can harm the environment. Since cardboard easily absorbs water, the researchers tested different mixtures of BP and SAL to determine which combination works best as a coating. Using ethanol maceration to extract hydrophobic compounds, epicuticular wax was obtained from SAL, while powdered BP was macerated with hexane. The extracts were concentrated …

Medical waste is an overlooked issue posing a significant environmental and public health threat, with 4.7 billion tons generated annually, accounting for 3% of overall waste, and wound dressing pads being a major contributor. Vitamin C, involved in all phases of wound healing, demonstrates synergy with Chitosan, a polysaccharide ideal for medical and cosmetic applications. Milkfish (Chanos chanos) skin, a dominant commercial fish in the Philippines, shows synergy with Chitosan and Vitamin C in wound healing. Thus, aligning with SDGs 3, 12, and 13, this study aims to synthesize and evaluate AsclePad, a sustainable wound dressing pad infused with Chitosan …

As urbanization rates rose, air pollution has become an increasing concern in our society, leading to poor air quality and several cases of respiratory diseases and illnesses. Adequate air quality levels were needed in indoor environments such as schools, as people spend the majority of their time indoors. Thus, this study aimed to assess the ambient air quality in the vicinity of the DLSU campuses in Manila and Laguna by determining the current level of Particulate Matter less than 2.5 microns (PM2.5) while also evaluating indoor air quality at two different locations in the Manila campus by measuring PM2.5 and …

With rising concerns over climate change and its impacts, this study develops and evaluates a Vector Autoregressive (VAR) model to forecast climatological data in General Santos City: surface pressure, specific humidity, wind speed, air temperature, precipitation, UVA and UVB irradiance, with data from January 1, 2001 to June 30, 2024. Mean hour calculations confirmed seasonality via the QS test (p < 0.001) for all variables except precipitation; Mann-Kendall tests indicated significant trends for all tested variables, and UV irradiances were the only variables with no significant long‐term trend. The Augmented Dickey-Fuller Test (p < 0.001) established stationarity of variables, and Granger‐causal relationships were identified. Results indicated a bidirectional Granger-causal relationship between variable pairs (p < 0.001). The AIC-based model selection identified VAR(168) as the best-fitting model, effectively capturing cyclic patterns up to one week. The residuals passed the Ljung-Box tests for no residual autocorrelation (p > 0.05), and OLS-CUSUM plots indicated structural stability. Mean root-mean-square error determined out-of-sample forecasting accuracy to be good for most variables, and poor for UVA and UVB irradiance; therefore, while the VAR(168) model does generate accurate forecasts, it still presents challenges. …

Heavy metal contamination in natural water sources poses a significant threat to public health, aquatic ecosystems, and environmental safety in affected communities. This study explores the utilization of Mango Peel Activated Carbon (MPAC), derived from ripe mango (Mangifera indica) peels, as a biosorbent for removing Iron(III) from aqueous solution, which underwent a sequence of physical and chemical activation processes. This examined key parameters such as A: adsorbent dosage (0.025–0.1 g/L), B: contact time (15–35 minutes), and C: temperature (25–35 °C), in order to assess its potential as a sustainable clean water solution. A Box-Behnken Design under Response Surface Methodology (RSM) …

One of the most important rivers in Iraq is the Tigris River, which serves as the primary source of drinking water and irrigation for agricultural purposes. In recent events, researchers have identified growing concerns about heavy metal contamination in the river. To decide the status of the Tigris River, the metal index (MI) was used in this study. To conduct this study, three locations were chosen along the river, and eight likely harmful heavy metals were examined: iron (Fe), lead (Pb), nickel (Ni), zinc (Zn), chromium (Cr), cadmium (Cd), manganese (Mn), and copper (Cu). The results were worrying. The metal …
Aquifer Characteristics And Groundwater Flow Modeling For Sustainable Water Resources Development And Planning Using Modflow Software In India, Ravi Sharma
AUIQ Complementary Biological System
MODFLOW is one of the most commonly used numerical models for simulating groundwater flow. Its structured data design and compatibility with GIS tools make it suitable for groundwater assessment and planning. Groundwater forms an important part of the hydrological cycle and occurs within the pore spaces of sedimentary rocks or within fractures in hard rock terrains. Although its distribution beneath the surface is not always uniform or predictable, it is still considered one of the cleanest, most accessible, and quickly available freshwater sources. Numerical groundwater models help convert complex subsurface processes into simplified relationships that describe flow behavior. Even though …
