The Effect Of Urbanization On Temperature Indices In The Philippines, John A. Manalo, Jun Matsumoto, Hiroshi G. Takahashi, Marcelino Q. Villafuerte Ii, Lyndon Mark P. Olaguera, Guoyu Ren, Thelma Cinco

Physics Faculty Publications

This paper presents a comprehensive analysis of the effect of urbanization on the surface air temperature (SAT) from 1951 to 2018 in the Philippines. The daily minimum temperature (T_min) and daily maximum temperature (T_max) records from 34 meteorological stations were used to derive extreme temperature indices. These stations were then classified as urban or rural based on satellite night-lights. The results showed a significant difference in the SAT trends between urban and rural stations, indicative of the effect of urbanization in the country. Larger and more significant warming trends were observed in indices related …

A Fused Radar–Optical Approach For Mapping Wetlands And Deepwaters Of The Mid–Atlantic And Gulf Coast Regions Of The United States, Brian T. Lamb, Maria A. Tzortziou, Kyle C. Mcdonald

Publications and Research

Tidal wetlands are critically important ecosystems that provide ecosystem services including carbon sequestration, storm surge mitigation, water filtration, and wildlife habitat provision while supporting high levels of biodiversity. Despite their importance, monitoring these systems over large scales remains challenging due to difficulties in obtaining extensive up-to-date ground surveys and the need for high spatial and temporal resolution satellite imagery for effective space-borne monitoring. In this study, we developed methodologies to advance the monitoring of tidal marshes and adjacent deepwaters in the Mid-Atlantic and Gulf Coast United States. We combined Sentinel-1 SAR and Landsat 8 optical imagery to classify marshes and …

Consumption Behavior Of Algerians During The Period Of The Covid-19 Pandemic Crisis, Kamel Chikhi

Markets, Globalization & Development Review

This Dialogue contribution is a reflection on the impact of crises and in particular that of Covid-19 on the behavior of Algerian consumers: before, during and post-crisis. It is recognized that during crises, consumers adopt unusual and more rational behaviors: buy basic necessities; save more to deal with possible difficult situations; place more importance on nutrition, health, food quality characteristics, price, psychological and socio-demographic characteristics; have purchasing and consumption intentions based on their cultural background and prefer to adopt planned behaviors. Observed events during the Covid-19 pandemic allows us to illustrate the evolution of consumption behavior of Algerians and to …

Non-Destructive Trace Element Analysis Of Burials From Moho Cay, Belize, April Alyce Walton

LSU Master's Theses

The study of skeletal material macroscopically and microscopically can yield a plethora of information about interments’ lives. Studying bones at an elemental level can provide further details regarding dietary habits, residency, and migration patterns, which are important areas of research for Maya archaeology. Currently, research on bone composition is conducted through destructive methods, especially for archaeological bone. The use of non-destructive methods for testing bone composition such as with a portable x-ray fluorescence machine can also be suitable for the study of archaeological bone. This study has two main goals: to understand the interments' lives through strontium trace element and …

Plant Biodiversity In Residential Yards Is Influenced By People's Preferences For Variety But Limited By Their Income, Allison Blanchette, Tara L.E. Trammell, Diane E. Pataki, Joanna Endter-Wada, Meghan L. Avolio

Environment and Society Faculty Publications

Residential yards are a unique component of the urban environment and harbor high cultivated plant biodiversity; however, why and how people create yards with so many plant species is not well understood. To investigate this pattern, we studied the relationships between residents’ preferences, income, and yard plant biodiversity in the Salt Lake Valley, Utah, USA where most of the urban vegetation is intentionally cultivated. We conducted in-person interviews, distributed written surveys, and inventoried the biodiversity (i.e., genus and species richness) of ornamental herbaceous flowering plants and lawn plants in residential yards located in neighborhoods across income levels. We found that …

Approximate Bayesian Computation Of Radiocarbon And Paleoenvironmental Record Shows Population Resilience On Rapa Nui (Easter Island), Robert J. Dinapoli, Enrico Crema, Timothy Reith, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Examining how past human populations responded to environmental and climatic changes is a central focus of the historical sciences. The use of summed probability distributions (SPD) of radiocarbon dates as a proxy for estimating relative population sizes provides a widely applicable method in this research area. Paleodemographic reconstructions and modeling with SPDs, however, are stymied by a lack of accepted methods for model fitting, tools for assessing the demographic impact of environmental or climatic variables, and a means for formal multi-model comparison. These deficiencies severely limit our ability to reliably resolve crucial questions of past human-environment interactions. We propose a …

Quantifying The Impact Of Urbanization On The Fourche Creek Watershed, Little Rock, Arkansas, Zachary Smith

Theses and Dissertations

The Fourche Creek Watershed is an urban watershed in Central Arkansas, serving as the primary drainage basin for most of metropolitan Little Rock. As land surrounding streams is developed, the risk of negatively impacting water quality through the addition of contaminants like metals, sewage, and pesticides increases. The objective of this project is to introduce a novel method of quantifying the impact of urbanization on streams using a multi-pronged approach including mixing and spatial analyses, dissolved loads, and 87Sr/86Sr ratios throughout the Fourche Creek Watershed to discern specific contributions of baseflow and urban materials into the drainage basin. Generally, Coleman …

The Contribution Of Mining Sector To Sustainable Development In Saudi Arabia, Mourad Zmami, Ousama Ben-Salha, Sultan O. Almarshad, Houyem Chekki

Journal of Sustainable Mining

The mining sector development is among the priorities of the Saudi Vision 2030. There is currently a lot of interest in the role of the mining sector in Saudi Arabia. This research contributes to this debate by empirically assessing the effects of mining on sustainable development in Saudi Arabia during the period 1980-2018. Unlike many previous studies, the three sustainable development dimensions, namely economic, social, and environmental, are jointly considered. The cointegration analysis, based on the ARDL, Gregory-Hansen, and combined cointegration tests, confirms the existence of long-run relationships between mining and all sustainable development dimensions. Furthermore, the findings lend substantial …

Bryophyte Ecosystem Services: How Bryophytes Impact Ecosystem Processes And Their Use In Urban Systems, Keila Spangler

University Honors Theses

Bryophytes, which include mosses, liverworts, and hornworts, are non-vascular plants that provide crucial ecosystem services in natural and urban systems. In natural systems, these services include carbon, water, and nutrient cycling and maintenance of community level biodiversity. In urban systems, bryophytes can be used as green roof substrate, as bioindicators to monitor pollution and air quality, for horticulture uses, and in medicine. Although bryophytes possess some qualities, such as reproduction by spores, that may give them an advantage compared to vascular plants as the climate warms, their response to climate change remains understudied. This paper will review the literature on …

Engaging Ecological Narratives: An Inquiry Into Place-Based Knowledge And Disaster Risk Reduction In Gozo, Malta, Ella S. Richmond

University Honors Theses

This paper utilizes fieldwork on the island of Gozo, Malta as a case study in understanding place-based environmental relationships. I employ a mixed methodology ethnographic approach to explore the disconnect between local narratives of hazard risk and those of larger institutional actors including the Maltese government, the EU, and the World Risk Index. This study reveals themes of: 1) language shaping climate discourse; 2) place-based oral histories and lore as impacting how risk is perceived; 3) tension between tradition and modernity in the realm of risk reduction; and 4) conflicting climate narratives characterizing the nature of preventative action. I argue …

Our Peer The Pigeon: Impacts Of The Covid-19 "Anthropause" On Psu Campus Urban Foragers, Audrey Douglass

University Honors Theses

The 2020 COVID Pandemic presented a paradigm shift dubbed, by some scholars, the 'Anthropause', an ecological epoch in which humans faded from the public sphere. As was the case for many urban species that depend on the foraging of food waste, this meant a fundamental disruption to their food systems and to the entire urban eco-web. The PSU Campus Park Blocks presents a unique opportunity to observe animal behavior, while also a succinct microcosm to study food waste flow changes, and compare species layout to other urban parks in the METRO area. Decreased food waste output from proximal …

Interactive Expert System For Budgeting World Bank Consultancy Projects, Yosra Rafat

Theses and Dissertations

Cost estimating and forecasting are key components of the budgeting of any construction project. However, conventional approaches may result in uncertainty and usually do not utilize the organizational knowledge of past projects. Ideally, performing a cost estimation under the best predictions of the relevant future conditions, is the best approach of economic analysis to evaluate the optimum value for money. With the rise of Artificial Intelligence techniques, there are now several Machine Learning (ML) methods that are being studied to capitalize on accuracy gains with regards to cost estimating techniques to increase reliability during the tendering phase. This research aims …

The Role Of Nature In Japanese American Internment Narratives: Julie Otsuka’S When The Emperor Was Divine., Brandon Mcwilliams

SUURJ: Seattle University Undergraduate Research Journal

The relocation and internment of US residents of Japanese heritage during World War II has been well documented, both historically and in literature. The critical examination of internment narratives has, however, largely failed to consider the highly consequential role of the natural environment in the internment experience and subsequent internment literature. In this paper, I examine Julie Otsuka’s When the Emperor was Divine, in conjunction with historical sources, through an ecocritical and environmental justice lens. In doing so, I reveal that the natural environment played a dual, and often contradictory, role in the internment experience. On the one hand, nature …

Congestion Pricing And The Opportunity To Confront New York City's Air Quality Emergency, Chad Hughes

William & Mary Environmental Law and Policy Review

Poor air quality in New York City is a public health emergency that disproportionately harms the city’s most vulnerable populations. Recent studies have found that exposure to particulate matter pollution previously thought “safe” causes significant damage to perhaps every organ of the human body. While New York City has reduced particulate matter exposure over the last decade, progress has stalled. In fact, climate change, the shift in the automobile market from sedans to SUVs and “light” trucks, and the federal pullback of environmental enforcement under Trump suggest that air pollution in New York City is likely to worsen.

Estimating Trail Use And Visitor Spatial Distribution Using Mobile Device Data: An Example From The Nature Reserve Of Orange County, California Usa, Noah E. Creany, Christopher A. Monz, Ashley D'Antonio, Abigail Sisneros-Kidd, Emily J. Wilkins, Jordan Nesbitt, Milan Mitrovich

Environment and Society Student Research

Monitoring visitor use in parks and protected areas (PPAs) provides essential information for managers of PPAs to evaluate aspects of the visitor experience and balance the ecological disturbance that use creates. Traditional methods for quantifying visitation and spatial use of PPAs are resource intensive and thus are conducted infrequently or at cost-effective intervals which may fail to capture the dynamic nature of modern visitor use trends. This paper provides an addition to a growing literature using mobile-device data to quantify visitation and spatial density of use of urban-proximate PPAs in Orange County, California, USA using the analysis platform Streetlight, Inc. …
