Enhancing Coastal Vulnerability Assessments And Policy Impacts On Socioeconomic And Environmental Equity In Michigan's Great Lakes Communities, Esther N. Acheampong Jan 2026

Enhancing Coastal Vulnerability Assessments And Policy Impacts On Socioeconomic And Environmental Equity In Michigan's Great Lakes Communities, Esther N. Acheampong

Dissertations, Master's Theses and Master's Reports

Accelerating shoreline erosion, fluctuating lake levels, and climate-induced hazards are transforming the Great Lakes’ freshwater coasts, exposing the limitations of static and inequitable management frameworks. This dissertation investigates how Michigan’s coastal governance systems produce and manage vulnerability along the Lake Michigan shoreline by integrating geospatial modeling, institutional policy analysis, and environmental justice theory. It argues that both physical processes and institutional designs co-determine patterns of exposure, protection, and equity. The research begins by developing a refined Coastal Vulnerability Index (CVI) tailored for lacustrine environments, applying it to Muskegon County to assess how shoreline change, armoring, and seasonality influence localized risk. …

Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado Dec 2025

Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate change is reshaping environmental conditions across Southeast Asia (SEA) through rising temperatures, altered precipitation patterns, and increased droughts. These changes alter transmission dynamics of neglected tropical diseases (NTDs) by shifting spatial distribution, increasing larval development rates, faster pathogen growth development, and increasing transmission rates. NTDs are a group of preventable and treatable infections that disproportionately affect more than 1 billion people globally, specifically in tropical and subtropical regions. A subgroup of NTDs, parasitic helminth infections (PHIs) - particularly schistosomiasis, soil-transmitted helminths, and lymphatic filariasis remains a public health concern in the Southeast Asian region. PHIs and their ecological responses …

Pharmacy and Wellness Review

Antimicrobial resistance is an escalating global threat driven by inappropriate antibiotic use and shaped by socioeconomic disparities. Social determinants of health, including limited healthcare access, poverty, low health literacy, and environmental conditions, contribute to higher rates of resistant infections and poorer treatment outcomes in underserved populations. Barriers such as pharmacy deserts, self-medication, and inadequate stewardship infrastructure amplify these risks. Pharmacists, as accessible and highly trained healthcare professionals, play a critical role in combating antimicrobial resistance by optimizing antibiotic use, delivering culturally competent education, and leading antimicrobial stewardship programs across settings. Community and clinical pharmacists are especially well positioned to bridge …

Faculty Scholarship

Ontologies have gained popularity in the scientific community as a way to standardize terminologies in organizations’ data. Although certain cohorts have created frameworks with rules and guidelines on creating ontologies, there exist significant variations in how Materials Science ontologies are currently developed. We seek to provide guidance in the form of a unified automated framework for developing interoperable and modular ontologies for Materials Data Science that simplifies the ontology terms matching by establishing a semantic bridge up to the Basic Formal Ontology(BFO). This framework provides key recommendations on how ontologies should be positioned within the semantic web, what knowledge representation …


The “Marketplace” Myth: Addressing Amazon’S Defense To Product Liability Claims, Andrew Ackley Mar 2025

The “Marketplace” Myth: Addressing Amazon’S Defense To Product Liability Claims, Andrew Ackley

Seattle University Law Review Online

Many courts continue to analyze law as if we have not evolved from the early days of the internet, when Facebook was a “social networking” site, AOL made messages “instant,” and eBay let everyone auction random items. The internet connected people. Because it did not touch them, it could not harm them. However, with storefronts closing, brick-and-mortar retail chains declaring bankruptcy, and “Uber lots” popping up at airports, the internet “cloud” has touched down all over the country, and online businesses are now harming people just as human actors and brickand-mortar stores always have.

The Impact Of Artificial Light At Night On The Distribution Of Sea Turtles In The Mediterranean, Molly R. Blyth Dec 2024

The Impact Of Artificial Light At Night On The Distribution Of Sea Turtles In The Mediterranean, Molly R. Blyth

The Plymouth Student Scientist

Artificial light at night (ALAN) poses a significant threat to a wide array of species across the world. In coastal areas, artificial lighting is known to disrupt sea-finding behaviour of sea turtle hatchlings and to deter females from nesting beaches. Yet, sea turtles spend the majority of their lifetimes in the sea, where the influence of ALAN on sea turtle distribution has not previously been studied. Using a recently published atlas of ALAN under the sea, this study analysed an online dataset of sea turtle sightings throughout the Mediterranean Sea, to look for a relationship using a binomial generalised linear …

Artificial Light At Night On Nesting Beaches Of The Green Turtle, Chelonia Mydas, In The Eastern Mediterranean And Its Possible Effect On Populations, Noam Leader, Yaniv Levy, Oğuz Türkozan

Turkish Journal of Zoology

Artificial light associated with coastal development is becoming one of the major threats to coastal biodiversity. Sea turtles are coastal breeders, and it is well-known that hatchlings tend to move toward lighter objects on the beach, which prevents them from reaching the sea. It is, therefore, essential to identify the impact of artificial light at night (ALAN) on the nesting beaches. Here, we investigated ALAN levels using imagery from satellites at important green turtle (Chelonia mydas) nesting beaches in the Mediterranean. Mean August radiance levels at nesting beaches ranged from 0.00473 nW/cm2sr (Northern Cyprus-South Karpaz Beach) to 14.44 nW/cm2sr (Turkey …

Predicted Spread In The Southeastern Us Of The Non-Native Lizard, Agama Picticauda, Based On Current And Future Climate, Sebastian Giddings Jan 2024

Predicted Spread In The Southeastern Us Of The Non-Native Lizard, Agama Picticauda, Based On Current And Future Climate, Sebastian Giddings

Harriet L Wilkes Honors College Theses 2020 - Present

Peters’s rock agama, Agama picticauda, is a West African lizard first observed in South Florida in 1975. It has since spread through much of the state and into southernmost Georgia. To better understand the potential spread of this invasive species in the southeastern US, I used Maxent species distribution models with native and non-native occurrences for A. picticauda with current and future bioclimatic variables. The models suggest that by 2100, the species could spread through all of Florida, much of Georgia, South Carolina, and North Carolina, and southern parts of Alabama, Mississippi, Louisiana, and Virginia.
