Many regions of the world are now facing more frequent and unprecedentedly large wildfires. However, the association between wildfire-related PM2·5 and mortality has not been well characterised. We aimed to comprehensively assess the association between short-term exposure to wildfire-related PM2·5 and mortality across various regions of the world.


Forest Structure Shapes Tropical Terrestrial And Arboreal Mesomammal Communities Under Moderate Disturbance, Juliana Masseloux Jan 2021

Forest Structure Shapes Tropical Terrestrial And Arboreal Mesomammal Communities Under Moderate Disturbance, Juliana Masseloux

Open Access Master's Theses

Tropical biodiversity is threatened globally by anthropogenic disturbances, particularly forest degradation and overhunting. Where large mammals have been extirpated, smaller-bodied “mesomammals” may play an important ecological role (e.g., as seed-dispersers). However, mesomammals are routinely understudied as they tend to be rare, cryptic, and nocturnal. Tropical tree-dwelling (arboreal and semi-arboreal) mesomammals are especially vulnerable to forest conversions, particularly when reliant on old growth forest structures. Understanding species- and community-level responses of terrestrial and arboreal mesomammals to changes in forest structure and human activity is crucial for informing management decisions in protected areas where resources are limited. We deployed 20 arboreal and …


Socio-Cultural Changes In New England Lobster Fisheries: Policy, Perspective, And Community In Midcoast Maine, Melanie Nash Jan 2021

Socio-Cultural Changes In New England Lobster Fisheries: Policy, Perspective, And Community In Midcoast Maine, Melanie Nash

Open Access Master's Theses

The Maine lobster industry is not only the most valuable local export, but also a part of the state’s culture and identity. Lobster fisheries in Maine are currently facing a number of struggles. These include environmental issues like climate change and warming water temperatures in the Gulf of Maine. These changes are leading to the movement of the lobster population, which in turn is changing how the lobster industry functions. There are also policy changes being proposed right now that could have serious implications for the lobster fishery. Notably, these include new offshore wind development in the Gulf of Maine …


Cognitive And Perceptual Barriers To Green Infrastructure: Local Decision-Making In Rhode Island, Kyle E. Gray Jan 2021

Cognitive And Perceptual Barriers To Green Infrastructure: Local Decision-Making In Rhode Island, Kyle E. Gray

Open Access Master's Theses

Green infrastructure uses natural and nature-based systems and practices to infiltrate and treat stormwater runoff at its source, lessening the burden and reliance on “gray” piped stormwater networks. Existing academic and governmental literature reports that local decision-makers face complicated cognitive and perceptual barriers that exacerbate other hindrances to green infrastructure implementation. These barriers are understudied at the local level in general, as well as in Rhode Island (“RI”) municipalities in particular. This study employs a literature review, semi-structured interviews with RI municipal officials, and thematic coding to describe the cognitive and perceptual barriers inhibiting wider green infrastructure implementation. Of the …


Research To Consider While Effectively Re-Designing Child Welfare Services, Richard P. Barth, Jill Duerr Berrick, Antonio R. Garcia, Brett Drake, Melissa Jonson-Reid, John Gyourko, Johanna K. P. Greeson Jan 2021

Research To Consider While Effectively Re-Designing Child Welfare Services, Richard P. Barth, Jill Duerr Berrick, Antonio R. Garcia, Brett Drake, Melissa Jonson-Reid, John Gyourko, Johanna K. P. Greeson

Department of Social Work - Faculty Scholarship

An intense appetite for reforming and transforming child welfare services in the United States is yielding many new initiatives. Vulnerable children and families who become involved with child welfare clearly deserve higher quality and more effective services. New policies, programs, and practices should be built on sound evidence. Reforms based on misunderstandings about what the current data show may ultimately harm families. This review highlights 10 commonly held misconceptions which we assert are inconsistent with the best available contemporary evidence. Implications for better alignment of evidence and reform are discussed.


The Compromises Progressive Prosecutors Must Make: Three Case Studies, Alexander John Kott Jan 2021

The Compromises Progressive Prosecutors Must Make: Three Case Studies, Alexander John Kott

Honors Papers

Elected prosecutors in the United States have facilitated mass incarceration, especially since 1994. In response, activists have helped to elect progressive prosecutors at the local level. This thesis examines whether prosecutors can achieve progressive goals, including increasing the fairness of the criminal justice process, prosecuting police abuse, and reducing incarceration. Based on three case studies, I find that prosecutors can reduce incarceration and increase the fairness of the criminal justice process, but that they currently face significant constraints in prosecuting police abuse. A prosecutor’s capacity to collaborate with more conservative agents is the most crucial factor for success and depends …


Grotesque, Bodily, And Hydrous: The Liminal Landscapes Of The Underworld In Homer, Virgil, And Dante, Sophia Zandi Jan 2021

Grotesque, Bodily, And Hydrous: The Liminal Landscapes Of The Underworld In Homer, Virgil, And Dante, Sophia Zandi

Honors Papers

This paper traces the liminal hydro-geologies of the Underworld through the works of Homer, Virgil, and Dante with the intention of understanding the Western Underworld as an ecosemiosphere—a mythological place with a close reciprocity to a physical environment. I focus on the entrances and margins of the infernal realm, the places where myth and world merge most intensely. Located in the fluid interspace between the world and the Underworld, this project is fundamentally about permeable boundaries. Particularly because of the boundary-crossing nature of fluids, water guides this journey into the margins of the nether realm. The infernal realm is accessible …

The Sustainable Groundwater Management Act (Sgma): Long Overdue, But Is It Living Up To Its Potential?, Bailey Mknelly Jan 2021

The Sustainable Groundwater Management Act (Sgma): Long Overdue, But Is It Living Up To Its Potential?, Bailey Mknelly

Scripps Senior Theses

This thesis discusses the Sustainable Groundwater Management Act (SGMA), California’s first statewide groundwater regulatory legislation. The act established the formation of groundwater basins and local governing bodies called Groundwater Sustainability Agencies (GSAs) which are tasked with creating Groundwater Sustainability Plans (GSPs). More specifically, this thesis examines how the structure of GSAs affects stakeholder accessibility, community engagement, and transparency. Through a collection of four interviews as well as the use of primary and secondary sources, this paper will explore the potential, and the ultimate shortcomings of SGMAs transparency, particularly in ensuring clean, safe water to historically disenfranchised communities. Using Kern and …


Summer Treatment Programs: Counselors And Care Practices, Christina X. You Jan 2021

Summer Treatment Programs: Counselors And Care Practices, Christina X. You

Scripps Senior Theses

Employing a mixed psychosocial and pharmacological approach, STPs offer six to nine weeks of intensive treatment for children deemed to have social and behavioral difficulties. One major asset STPs claim is their natural, fun setting—a true summer camp space for activities and open peer interaction—in which children learn positive behaviors that they can generalize into external social settings. Yet STPs are also highly structured. Staff, who are often undergraduate and graduate students, are trained in operant learning strategies to promote “positive” and suppress “maladaptive” behaviors, strict activity guidelines, and evaluations for procedural adherence. The program was developed based on the …

Ancient Maya Rural Settlement Patterns, Household Cooperation, And Regional Subsistence Interdependency In The Río Bec Area: Contributions From G-Liht, Scott R. Hutson, Nicholas P. Dunning, Bruce Cook, Thomas Ruhl, Nicolas C. Barth, Daniel Conley

Anthropology Faculty Publications

Research on intensive agricultural features contributes to the social relations of farming, including the means by which farmers mobilize labor and the possible destination of surplus. Lidar provides high-resolution data on ancient houses and agricultural features at a regional scale. This paper uses lidar data from NASA’s G-LiHT airborne imager to derive insights about rural demography, interhousehold cooperation, and subsistence interdependency among the ancient Maya. We assess the differences in intensity of agricultural investment in rural and urban areas of the Río Bec region of southern Campeche and Quintana Roo, Mexico, leading to inferences about regional food exchange and complex …


Ever-Present “Illegality:” How Political Climate Impacts Undocumented Latinx Parents’ Engagement In Students’ Postsecondary Access And Success, Stephany Cuevas Jan 2021

Ever-Present “Illegality:” How Political Climate Impacts Undocumented Latinx Parents’ Engagement In Students’ Postsecondary Access And Success, Stephany Cuevas

Journal of College Access

Using the ecological systems theory, this study highlights the significant impact the political climate in the United States (i.e., anti-immigrant sentiments and violence) has on undocumented Latinx parents’ engagement in their children’s education. Drawing from a larger qualitative, interview-based study that explored how undocumented Latinx parents were involved and engaged in their children’s postsecondary access and success (Cuevas, 2019; 2020), this study focuses on undocumented parents’ experiences and processing of the 2016 Presidential Election. Findings illustrate how the explicit racist, anti-immigrant, and nativist narratives then-Republican Presidential Candidate Donald Trump campaigned under and won forced undocumented Latinx parents to (re)evaluate how …


Essays In Spatial And Regional Economics, Mohamed Shabani Kariburyo Jan 2021

Essays In Spatial And Regional Economics, Mohamed Shabani Kariburyo

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays in spatial and regional economics. In the first essay, high rates of chronic diseases and increasing nutritional polarization between different income groups in the United States are shown to be issues that should concern policymakers and public health officials. Spatial differences in access to food are evaluated as the cause of these nutritional inequalities. In this essay, hot and cold spots for food providers are determined throughout the state of West Virginia and then those places are used in a quasi-experimental method (entropy balancing) to study the effects of hot and cold spots on …

The Immigrant In Our Head: Skin Tone, Social Categorization, And Support For Policy, Patrizia Chirco Jan 2021

The Immigrant In Our Head: Skin Tone, Social Categorization, And Support For Policy, Patrizia Chirco

All Master's Theses

Researchers in diverse fields such as psychology, sociology, anthropology, and geography have extensively researched push and pull factors that lead to migrations (Castles et al., 2014) as well as the political and economic consequences that migrations have on both sending and receiving countries (Golash-Boza, 2015). However, relatively little research is published on whether markers of racial categorization affect the social classification of immigrants, their legal status, and the relationship between support for immigration policies and specific patterns of categorization. In the current research, I investigated whether social categorizations of individuals as undocumented immigrants depend on phenotypes (i.e., skin tone), and …


A Regional Synthesis Of Post-Glacial Fire History In The Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis, Brynn Harrison Jan 2021

A Regional Synthesis Of Post-Glacial Fire History In The Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis, Brynn Harrison

All Master's Theses

The recent rise in severe wildfires in the Pacific Northwest (PNW) has created a heightened sense of urgency and reignited public interest in wildfire risk. In order to put this rise into a broader spatial and temporal context, a more in-depth look at fire histories from frequently burned areas in the eastern Cascades is needed. The first major objective of this study was to determine if CharAnalysis, a statistical program developed to reconstruct fire history from macroscopic charcoal-based records, is appropriate for use with charcoal records from the eastern Cascades of Washington. The second major objective was to develop a …


Quantifying The Impact Of Remapping Floodplains On Residential Property Values In Snohomish County, Washington: A Hedonic Approach, Carson Joseph Risner Jan 2021

Quantifying The Impact Of Remapping Floodplains On Residential Property Values In Snohomish County, Washington: A Hedonic Approach, Carson Joseph Risner

All Master's Theses

Flood events are the most common and costly natural disasters. The Federal Emergency Management Agency (FEMA) quantifies flood risks in the form of Flood Insurance Rate Maps (FIRMS). These FIRMS delineate flood risks and are used to set flood insurance premiums. Changes in land use, the augmentation of the natural environment, is threatening the validity of the Nation’s FIRMS. Therefore, Congress has approved remapping programs to update these FIRMs ensuring that current flood risks are known. This remapping presents another issue, specifically for properties that are remapped into a flood zone. Current literature suggests that properties within flood zones are …


An Analysis Of Tachylyte And Other Volcanic Glasses In Washington Archaeology, Mallory M. Triplett Jan 2021

An Analysis Of Tachylyte And Other Volcanic Glasses In Washington Archaeology, Mallory M. Triplett

All Master's Theses

Within archaeological literature, a discussion of volcanic toolstones from Washington State is uncommon. Washington’s volcanic glass landscape is relatively sparse, with low-quality sources scattered within and on the east side of the Cascades, including tachylyte, obsidian, and vitrophyric obsidian. Tachylyte is a volcanic glass that forms within low-silica, basalt flows while obsidian comes from high-silica, usually rhyolitic, eruptions. Vitrophyric is a textural term used to describe an igneous rock that has a glassy groundmass with conspicuously large crystals. The low-quality and dispersed nature of these toolstones are reflected in Washington’s archaeological record by the more common occurrence of out-of-state volcanic …


Songs From The Sea : Maritime Influence On Indonesian Popular Songs In The 1980s, Abdullah Sammy Jan 2021

Songs From The Sea : Maritime Influence On Indonesian Popular Songs In The 1980s, Abdullah Sammy

Journal of Urban Culture Research

This study examines the influence of maritime affairs on the development of Indonesian popular music in the 1980s. During the 1980s period, maritime events and issues became one of the discourses that developed in society. This is inseparable from the burning incident of the Tampomas II ship which resulted in hundreds of deaths. Not only the Tampomas II tragedy, the 1980s was marked by the issue of damage to marine ecosystems in Indonesia. This research reveals that Indonesian music is heavily influenced by maritime elements. Almost all traditional Indonesian music in each region touches on maritime elements. The same applies …


Class And Urban Public Space Consumption: A Typology In Isfahan, Iran, Kamran Rabiei, Shamin Golrokh, Zahra Bahrami Jan 2021

Class And Urban Public Space Consumption: A Typology In Isfahan, Iran, Kamran Rabiei, Shamin Golrokh, Zahra Bahrami

Journal of Urban Culture Research

This paper, adopting an interpretive approach, focuses on the spatiality of class to describe how social class represents itself through public space consumption. The paper presupposes public space consumption as a lived experience by class and explores it through analyzing the narratives of citizens in the city of Isfahan, Iran. According to Bourdieu's notion of social space, four different economic-cultural positions are purposefully selected as under-studied social categories. Cultural (occupation, professional skills and education) and economic attributes (income, house ownership and the neighborhood where they live) are considered for the categorization. Applying a qualitative content analysis, this paper uses semi-structured …

Environmental Controls On The Skeletal Mineralogy Of Marine Calcifiers, Kilian Eichenseer Jan 2021

Environmental Controls On The Skeletal Mineralogy Of Marine Calcifiers, Kilian Eichenseer

School of Geography, Earth and Environmental Sciences Theses

Calcifying organisms secrete skeletons consisting of calcium carbonate (CaCO3). The two principle CaCO3 polymorphs used by marine calcifiers are aragonite and calcite. In the abiotic precipitation of CaCO3, the Mg/Ca ratio and the temperature are established controls of polymorph formation, but the importance of other factors, for example salinity, remains uncertain. The first objective of this thesis was to clarify the role of salinity in abiotic CaCO3 precipitation (Chapter 2). Experiments at salinities of 20, 35 and 50 and a Mg/Ca ratio of 2 resulted in co-precipitation of aragonite and calcite in all experiments, and no significant salinity influence on …


Rare Metal Resources In Polymetallic Nodules From The Eastern Equatorial Pacific Ocean, Wycliff Tupiti Jan 2021

Rare Metal Resources In Polymetallic Nodules From The Eastern Equatorial Pacific Ocean, Wycliff Tupiti

School of Geography, Earth and Environmental Sciences Theses

The Clarion-Clipperton fracture zone (CCFZ) in the eastern equatorial Pacific is the area with the greatest interest in terms of metal resources in polymetallic nodules. The nodules are enriched (relative to crustal composition) in economically important metals such as Mn, Ni, Cu, Zn, and so-called critical metals such as Co, Rare Earth Elements and Y (REYs). This project involves the geochemical and mineralogical investigation of nodules from five box cores from the UK claim area in the CCFZ. Bulk geochemical analysis shows that the nodules formed from both hydrogenetic (precipitation from bottom oxic seawater) and diagenetic (precipitation from oxic/suboxic sediment …


Optimising Oak Woodland Establishment Into Uk Upland Pastures In The Context Of Climate Change; And The Role Of Oak Woodland In Soil Hydrological Recovery For Natural Flood Management, Thomas Murphy Jan 2021

Optimising Oak Woodland Establishment Into Uk Upland Pastures In The Context Of Climate Change; And The Role Of Oak Woodland In Soil Hydrological Recovery For Natural Flood Management, Thomas Murphy

School of Geography, Earth and Environmental Sciences Theses

Increases in the magnitude and extremity of upland (>250-300m a.s.l.) precipitation associated with anthropogenic climate change (ACC) and coinciding with soil compaction leave downstream communities at elevated flood risk. The study examines changes in upland precipitation and the impact of upland ‘Atlantic’ oak (Quercus robur, Quercus petraea) woodland establishment on the recovery of soils for natural flood management (NFM). The soil moisture, livestock grazing and dispersal constraints for potential oak woodland expansion in upland pastures are assessed. The study is located within Dartmoor National Park (DNP) and finds greater increases in precipitation in upland areas than the lowland site, …


Evaluating The Emerging Environmental Risks Of Mycotoxins In Freshwater Ecosystems., Emily Eagles Jan 2021

Evaluating The Emerging Environmental Risks Of Mycotoxins In Freshwater Ecosystems., Emily Eagles

School of Geography, Earth and Environmental Sciences Theses

Deoxynivalenol (DON) and zearalenone (ZON) are two of the prominent mycotoxins which regularly contaminate food, both of these natural toxins are produced by fungi within the Fusarium genus. With the known widespread occurrence of these toxins in cereal crops there has been rising interest into the potential transference into freshwaters. Multiple reports of mycotoxin occurrence in freshwater samples have led to their consideration as natural chemicals of emerging concern, particularly with ZON seen to act in an oestrogenic nature, yet the ecotoxicological data to support analysis of risk to freshwater ecosystems is lacking. The main aim of this work was …


Lithological And Climatic Controls On Fluvial Landscape Evolution Of A Post-Orogenic Dryland Mountain Belt, Jesse Ruben Zondervan Jan 2021

Lithological And Climatic Controls On Fluvial Landscape Evolution Of A Post-Orogenic Dryland Mountain Belt, Jesse Ruben Zondervan

School of Geography, Earth and Environmental Sciences Theses

Many mountain ranges in the world are in post-orogenic decay, a stage in which erosion is dominant over crustal thickening. The dominance of regional isostatic and mantle controls on rock uplift over localised fault uplift means climatic changes and intrinsic properties such as drainage capture and lithological variations are principal drivers of landscape evolution. In addition, dryland conditions in low to mid-latitude settings with negligible glacial ice cover result in fluvial processes forming a primary agent of erosion. This thesis investigates the lithological and structural control on long-term fluvial mountain landscape evolution, using a synthesis of detailed field observations and …


Across The River: Ferries As A Vehicle For Exploring Riverborderscapes, Eva Mcgrath Jan 2021

Across The River: Ferries As A Vehicle For Exploring Riverborderscapes, Eva Mcgrath

School of Geography, Earth and Environmental Sciences Theses

This thesis uses the concept of the riverborderscape to provide new understandings of watery geographies, borders and landscape. This is a spatial and conceptual term used to explore the space of the river through a holistic approach, focusing upon the materialities, experiences and narratives that shape, emerge within and construct this space. These ideas are applied in relation to three rivers that form an everyday border between places at different scales in the South West of England: the River Tamar (regional), River Torridge (district) and Helford River (parish). Research is situated on and across the river, through the routes of …
