Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Low-Cost Pm2.5 Sensors Can Help Identify Driving Factors Of Poor Air Quality And Benefit Communities, Tim Keyes, Rea Domingo, Samantha Dynowski, Royal Graves, Martha Klein, Melissa Leonard, John Pilgrim, Alison Sanchirico, Kate Trinkaus

WCBT Faculty Publications

Air quality is critical for public health. Residents rely chiefly on government agencies such as the Environmental Protection Agency (EPA) in the United States to establish standards for the measurement of harmful contaminants including ozone, sulfur dioxide, carbon monoxide, volatile organic chemicals (VOCs), and fine particulate matter at or below 2.5 μm. According to the California Air Resources Board [1], “short-term PM2.5 exposure (up to 24-h duration) has been associated with premature mortality, increased hospital admissions for heart or lung causes, acute and chronic bronchitis, asthma attacks, emergency room visits, respiratory symptoms, and restricted activity days”. While public agency resources …

The Role Of E-Liquid Constituents In E-Cigarette-Induced Cardiac Arrhythmia And Autonomic Imbalance., Cory Kucera

Electronic Theses and Dissertations

Introduction. Accumulating evidence indicates that exposure to electronic cigarettes (e-cigs) promotes sympathetic dominance and electrophysiologic instability in the heart, potentially culminating in arrhythmogenesis. E-liquids contain various formulations of nicotine and flavorings, but the effects of specific e-liquid constituents and their concentrations on e-cig-induced autonomic imbalance and electrical dysfunction are unresolved. To that end, we tested the hypothesis that e-cigs modify cardiac autonomic balance and ventricular arrhythmogenesis in mice dependent on e-liquid constituent type and concentration. Methods. Using a crossover design and a serial exposure regimen, ECG-telemetered male C57BL/6J mice underwent whole-body exposure to e-cig aerosols generated from e-liquids containing different …

Barriers To Public Health In Latino American Indigenous Communities, Wilzave Quiles Guzman

Honors Program Theses and Research Projects

This paper focuses on barriers to public health in Latino American Indigenous communities. Indigenous people throughout the world are at a public health disadvantage due to a lack of clearly defined practices within the decision-making processes to plan, evaluate, and control finances from governmental and non-governmental entities in charge of managing health services. I argue that political, social, and institutional changes are still needed to achieve health equity in Indigenous communities and that these changes should go beyond implementing a universal health care program. I must recognize improvements made by many Latino American countries like Brazil, which prepared a plan …

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …

Environmental Justice Analysis Of Drinking Water Policies In Michigan Cities, Annika Paldan

Honors Theses

This thesis examined environmental justice aspects of drinking water policies in four cities across Michigan: Flint, Birmingham, St. Joseph, and Benton Harbor. An overview of the history of the environmental justice movement, environmental racism, and drinking water policies provided the basis for a four-part evaluative criterion to assess environmental justice components at the municipal level. These criteria include (1) housing tenure, (2) age, size, and service line composition of the infrastructure, (3) public participation in the policy process, and (4) emergency management of the city. Findings indicate that environmental justice has come a long way, with cities now incorporating components …

Allergy And Anaphylaxis From The Prehospital Perspective, Anthony E. Conrardy

Dissertations and Theses

Anaphylaxis is considered a severe, potentially fatal, systemic allergic reaction that occurs suddenly after contact with an allergy causing substance. It is estimated that up to 5% of the population has experienced anaphylaxis, with 1% of hospitalizations and 0.1% of emergency department patients having fatal outcomes. We characterized the population of patients encountered by the EMS agency (786 patients) that had a provider impression of “allergic reaction” and then utilized logistic regression models to estimate associations with the administration of epinephrine in the prehospital setting. Additionally, we used incident location data for all patient encounters of the EMS agency …

Environmentally Marginalized Populations: The "Perfect Storm" For Infectious Disease Pandemics, Including Covid-19, Gabriella Y. Meltzer, Oyemwenosa Avenbuan, Christina Awada, Oluwakemi B. Oyetade, Tricia Blackman, Simona Kwon Drph, Mph, Esther Erdei Phd, Judith T. Zelikoff Phd

Journal of Health Disparities Research and Practice

COVID-19 has exacted a severe toll on the United States population’s physical and mental health and its effects have been felt most severely among people of color and low socioeconomic status. Using illustrative case studies, this commentary argues that in addition to COVID-19 health disparities created by psychosocial stressors such as the inability to socially distance and access quality healthcare, environmental justice communities have the additional burden of disproportionate exposure to toxic contaminants that contribute to their higher risk of COVID-19. Environmental contaminants including heavy metals and persistent organic pollutants found contaminating their nearby environments can alter the immune response, …
