Power To The People? An Evaluation Of State-Level Environmental Justice Policies, Angela Michelle Hines May 2014

Power To The People? An Evaluation Of State-Level Environmental Justice Policies, Angela Michelle Hines

Graduate Theses and Dissertations

Communities of color in America lacking economical, educational, and political power have been largely invisible in the process of making major policy decisions. This is lack of access to decision-making venues has been viewed by many as the reason behind marginalized populations bearing the brunt of many societal burdens. The Environmental Justice Movement legitimized the claims of inadequate access to the decision-making process concerning environmental conditions in which African-Americans lived and worked. Through the use of disruptive actions reminiscent of those used throughout the Civil Rights Movement, the plight of communities plagued by the daily presence of hazardous waste gained …

Historical Health Conditions In Major Us Cities: The Hue Data Set, Carlos Villareal, Brian Bettenhausen, Eric Hanss, Jonathan Hersh

Economics Faculty Articles and Research

The Historical Urban Ecological data set is a new resource detailing health and environmental conditions within seven major U.S. cities during the study period from 1830 to 1930. Researchers collected and digitized ward-level data from annual reports of municipal departments that detail the epidemiological, economic, and demographic conditions within each city. They then drafted new geographic information system data to link the tabular records to ward geographies. These data provide a new foundation to revisit questions surrounding the urban mortality transition and the growth of U.S. cities.

Public Transportation: Perceptions Of Filth Contributing To Poor Health, Dashka Bernard Apr 2014

Public Transportation: Perceptions Of Filth Contributing To Poor Health, Dashka Bernard

Annual Undergraduate Conference on Health and Society

Public transportation vehicles such as trains or buses have a reputation as unsanitary. Many riders of public transit are concerned with the health risks they are facing in regards to contagion. Perceptions of cleanliness derive from public health historically, with class, morality, and good health tied together in the American public’s attitudes. Certainly, infectious disease and sanitation are directly correlated in many instances, such as in the highly overcrowded and dirty cities in the early twentieth-century United States. Those living in filthy conditions (particularly, lower class individuals) were not only prone to becoming ill, but also considered to be immoral …


Defining Obesity: An Argument For The Social Environment Perspective, Meghan Mcinnis Apr 2014

Defining Obesity: An Argument For The Social Environment Perspective, Meghan Mcinnis

Annual Undergraduate Conference on Health and Society

It is well documented that obesity is a growing problem in the U.S. and worldwide. By 2010, 35.9% of U.S. adults age 20 and older were obese (Overweight and Obesity, CDC). Obesity has been associated with many health problems, including hypertension, type 2 diabetes, osteoarthritis, stroke, and cardiac disease (Lucey, 2008, p.202). What has just been described is the traditional, medicalized narrative of obesity. In this narrative, obesity is viewed as an epidemic that demands an immediate and widespread response (Lucey, 2008, p.202). The blame is placed largely on individuals, while social factors, such as socioeconomic status and neighborhood environment, …

Relationship Between Altitude And Lithium In Groundwater In The United States Of America: Results Of A 1992–2003 Study, Rebekah S. Huber, Namkug Kim, Carl E. Renshaw, Perry F. Renshaw, Douglas Kondo

Dartmouth Scholarship

Therapeutic dosages of lithium are known to reduce suicide rates, which has led to investigations of confounding environmental risk factors for suicide such as lithium in groundwater. It has been speculated that this might play a role in the potential relationship between suicide and altitude. A recent study in Austria involving geospatial analysis of lithium in groundwater and suicide found lower levels of lithium at higher altitudes. Since there is no reason to suspect this correlation is universal given variation in geology, the current study set out to investigate the relationship between altitude and lithium in groundwater in the United …

Humidity And Gravimetric Equivalency Adjustments For Nephelometer-Based Particulate Matter Measurements Of Emissions From Solid Biomass Fuel In Cookstoves, Sutyajeet Soneja, Chen Chen, James M. Tielsch, Joanne Katz, Scott L. Zeger, William Checkley, Frank C. Curriero, Patrick L. Breysse

Global Health Faculty Publications

Great uncertainty exists around indoor biomass burning exposure-disease relationships due to lack of detailed exposure data in large health outcome studies. Passive nephelometers can be used to estimate high particulate matter (PM) concentrations during cooking in low resource environments. Since passive nephelometers do not have a collection filter they are not subject to sampler overload. Nephelometric concentration readings can be biased due to particle growth in high humid environments and differences in compositional and size dependent aerosol characteristics. This paper explores relative humidity (RH) and gravimetric equivalency adjustment approaches to be used for the

pDR-1000 used to assess indoor PM …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Investigating The Interactions Between Cyanobacteria And Vibrio Parahaemolyticus, Caroline E. Ward Jan 2014

Investigating The Interactions Between Cyanobacteria And Vibrio Parahaemolyticus, Caroline E. Ward

Honors Theses and Capstones

One well-known pathogen that has been the topic of many recent studies is Vibrio parahaemolyticus, which causes thousands of foodborne illnesses a year, mostly from the ingestion of raw or undercooked oysters. It has been shown cyanobacteria can act as a long-term reservoir of Vibrio cholerae, another pathogenic Vibrio, by encasing the cells within mucilaginous sheaths during which Vibrios enter a viable but non-culturable state. In this study we investigated the interaction of V. parahaemolyticus with cyanobacteria to determine whether cyanobacteria aid in the longevity and survival of V. parahaemolyticus. We found that non-pathogenic V. parahaemolyticus …

Fly ash is a byproduct of the combustion of coal, primarily by coal-fired power plants. Over 97.8 million tonnes of fly ash are produced each year in the United States. Fly ash can contain trace elements in concentrations that can cause health risks. Recent spills have highlighted that fly ash disposal is problematic. The objective of this study was to evaluate the effects of fly-ash type (fresh and weathered) from a local coal-burning power plant and extraction time (2 and 6 h) on dilute-acid extractable concentrations of phosphorus (P), arsenic (As), and selenium (Se). Ash samples were extracted with 0.1 …


Presence Of Antibiotic Resistance Genes From Wastewater Treatment Plant Effluent In Northwest Arkansas, Ryan Macleod, Mary Savin Jan 2014

Presence Of Antibiotic Resistance Genes From Wastewater Treatment Plant Effluent In Northwest Arkansas, Ryan Macleod, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Antibiotic resistance genes (ARGs) among bacterial populations are causing increasing concern with medical and agricultural implications. While the effluent of wastewater treatment plants (WWTPs) is treated with a variety of antimicrobial methods, bacteria and the genetic material that is able to pass on antibiotic resistance to environmental populations are not completely destroyed. Ampicillin (amp), tetracycline (tet), and sulfonamide (sul) antibiotics have been detected in Northwest Arkansas (NWA) streams, and IncP plasmids—which are especially notorious for containing antibiotic resistance genes and have been detected after disinfection in NWA WWTPs—are known to carry ARGs for those antibiotics. The objective of this inquiry …


Environmental Factors And Progressive Myopia: A Global Health Problem, Jeffrey Weissman Jan 2014

Environmental Factors And Progressive Myopia: A Global Health Problem, Jeffrey Weissman

The Science Journal of the Lander College of Arts and Sciences

Myopia, or nearsightedness, is a refractive error whose prevalence has increased over the past three decades, leading to a growing concern and interest among both the public and scientific communities. For years, the only explanation and basis for myopia has been genetic factors. However, the genetic model does not explain the dramatic increase in prevalence. Current research suggests that the increase is also due to environmental factors, such as fewer hours of outdoor activities, early educational pressures requiring intense close work, as well as a lack of exposure to sunlight. One study compared the prevalence and risk factors for myopia …

Wild birds are the primary source of genetic diversity for influenza A viruses that eventually emerge in poultry and humans. Much progress has been made in the descriptive ecology of avian influenza viruses (AIVs), but contributions are less evident from quantitative studies (e.g., those including disease dynamic models). Transmission between host species, individuals and flocks has not been measured with sufficient accuracy to allow robust quantitative evaluation of alternate control protocols. We focused on the United States of America (USA) as a case study for determining the state of our quantitative knowledge of potential AIV emergence processes from wild hosts …
