Systems Of Meaning In Place Attachment, Emily Routman

Geography and the Environment Capstone Projects

Numerous scholars agree that contact with natural landscapes has benefits for the landscape and the person experiencing them, including increased environmentally-responsible behaviors as well as psychological, cognitive, physiological, and social benefits. People develop a sense of place in outdoor landscapes while experiencing the physical environment, and sense of place is strengthened by place attachment – one’s emotional ties to a place. According to Williams and Patterson (1999), place attachment is perceived through four systems of meaning: 1) aesthetic/inherent, 2) goal-directed/instrumental, 3) cultural/symbolic, and 4) individual/expressive. The present study sought to understand which of these four systems of meaning are the …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

Earth Observation And Cloud Computing In Support Of Two Sustainable Development Goals For The River Nile Watershed Countries, Wenzhao Li, Hesham El-Askary, Venkat Lakshmi, Thomas Piechota, Daniele Struppa

Mathematics, Physics, and Computer Science Faculty Articles and Research

In September 2015, the members of United Nations adopted the 2030 Agenda for Sustainable Development with universal applicability of 17 Sustainable Development Goals (SDGs) and 169 targets. The SDGs are consequential for the development of the countries in the Nile watershed, which are affected by water scarcity and experiencing rapid urbanization associated with population growth. Earth Observation (EO) has become an important tool to monitor the progress and implementation of specific SDG targets through its wide accessibility and global coverage. In addition, the advancement of algorithms and tools deployed in cloud computing platforms provide an equal opportunity to use EO …

Home: Recreated In A College Setting, Hannah Huggins

Departmental Honors & Graduate Capstone Projects

There has been virtually no research on college students’ re-creations of home on college campuses. This research seeks to address this gap in literature and investigate the re-creation of home by college students on college campuses through a qualitative analysis of student experiences in on-campus housing at the University of Mary Washington. Qualitative, semi-structured interviews were used to understand individual student perspectives on home and home re-creation. Home re-creation on college campuses is an individual and complex process. No single feature or collections of features transform a space into home for everyone. Main elements that create a sense of home …

280— Exploring The Geographic Distribution Of Childbed Fever Deaths In Mid-19th Century Rochester, Ny, Meaghan Parks

GREAT Day Posters

Childbed fever, formally called puerperal fever or puerperal septicemia, is an infection typically contracted by women after childbirth. Historically, childbed fever was a serious threat to maternal health. Childbed fever is caused by exposure of open wounds or abrasions, which are common after giving birth, to group A and B Streptococcal bacteria. Ignaz Semmelweis discovered that hand washing using a chlorinated solution reduced cases of childbed fever in 1847. This project reviews the instances of death from childbed fever in Rochester, New York from 1837-1860 and later from 1907-1919 and attempts to determine which areas of the city had the …

216— Using Rochester’S Family Public Housing In The “Crescent Of Poverty” As A Catalyst For A Solar Initiative, Christopher Miller

GREAT Day Posters

Both the climate crisis and poverty rates in US cities have increased rapidly, with few solutions. This research examines the relative solar potential in public housing developments in Rochester, NY, specifically in the area of concentrated poverty called the “Crescent of Poverty.” Also examined are societal benefits that an inclusive solar/sustainability movement provides for Rochester. Rochester is a mid-sized, diversely populated city with an overall poverty rate >30% and a childhood poverty rate >50% (Murphy, 2018). These alarming rates have contributed to the creation of the “Crescent of Poverty”, where the majority of family public housing developments are located. Solar …

228— Biden's Bounce: The African American Vote And Biden's South Carolina Comeback, Rachel Morris

GREAT Day Posters

On February 29, 2020, registered Democrats across South Carolina came out to vote for their preferred primary candidate. At the time of this primary, former Vice President Joe Biden needed a win to show that he was still a contender in the race. As the poles closed that night, it was clear that South Carolina was going to give Biden the win and this momentum eventually propelled his campaign to a bigger win on Super Tuesday. South Carolina is an important primary state with 63 delegates available, and it can make or break a candidate’s chance of securing the nomination. …

Philosophical Perspectives, Jochen Albrecht

Publications and Research

This entry follows in the footsteps of Anselin’s famous 1989 NCGIA working paper entitled “What is special about spatial?” (a report that is very timely again in an age when non-spatial data scientists are ignorant of the special characteristics of spatial data), where he outlines three unrelated but fundamental characteristics of spatial data. In a similar vein, I am going to discuss some philosophical perspectives that are internally unrelated to each other and could warrant individual entries in this Body of Knowledge. The first one is the notions of space and time and how they have evolved in …

Crude Oil Spill Response In The Great Lakes Region: Before And After The 2010 Kalamazoo River Enbridge Oil Spill, Marshall Kim

Honors Theses

Pipeline infrastructure is a particularly sensitive and unique energy transport mode. Pipelines carry gas, biofuels and liquid petroleum throughout the United States (U.S. Department of Transportation, 2019). These pipelines stretch beneath sensitive ecological areas, lakes, rivers and streams, and our homes and businesses. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA) (2018), between all of the states in the Great Lakes region (Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and New York) there is a cumulative 801,718 miles of pipeline. This includes interstate and intrastate, natural gas and petroleum pipelines. 9,556.9 miles of this is the interstate …

Faculty Publications

This study provides a systematic comparison of lidar, Multibeam Echo Sounders (MBES), and Structure-from-Motion (SfM) derived datasets collected over a fixed surface contained within a large outdoor flume converted to a 15 × 2.5 × 1.5 m tank. The surface incorporated various morphological features and structures for measurement technique comparison over varying surface type and geometries. Two lidar scans and two photograph sets (used in SfM) capture the subaerial surface within the experimental tank before and after the tank was filled for MBES measurements. MBES surveys at varied frequencies (200 and 400 kHz), swath widths (90° and 150°), and phase/amplitude …

Drinking Water Governance For Whom? An Institutional Analysis Of Rural Drinking Water Systems In New Mexico, Tucker Colvin

Geography ETDs

Rural community drinking water systems in New Mexico are facing many challenges, including a lack of personnel, deteriorating infrastructure, lack of funds, overly burdensome and confusing regulation, environmental concerns, and concerns over water rights. Governing agencies are creating vulnerability by making managers prioritize some issues and neglect others. Water systems designated a Mutual Domestic Water Consumers Associations are especially problematic because they are small and managed by volunteers but have as much regulatory burden as larger municipalities. I use the theory of institutional work to explain how an institution that was originally designed to help low-income and rural communities is …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

Automatic Features Extraction From Time Series Of Passive Microwave Images For Snowmelt Detection Using Deep-Learning – A Bidirectional Long-Short Term Memory Autoencoder (Bi-Lstm-Ae) Approach., Bienvenu Sedin Massamba

LSU Master's Theses

The Antarctic surface snowmelt is prone to the polar climate and is common in its coastal regions. With about 90 percent of the planet's glaciers, if all of the Antarctica glaciers melted, sea levels will rise about 58 meters around the planet. The development of an effective automated ice-sheet snowmelt monitoring system is therefore crucial.

Microwave remote sensing instruments, on the one hand, are very sensitive to snowmelt and can see day and night through clouds, allowing us to distinguish melting from dry snow and to better understand when, where, and for how long melting has taken place. On the …

An Atmospheric And Spatiotemporal Examination Of Lightning-Initiated Terrestrial Gamma-Ray Flashes Detected By The Fermi Satellite And Tetra Ii, Deirdre Colleen Smith

LSU Doctoral Dissertations

Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of the highest naturally occurring light-energy found within Earth’s atmosphere. TGFs are associated with the electric fields produced in thunderstorms and are geolocated by coincident sferics from lightning strokes. Though billions of lightning strokes occur globally each year, fewer than 1,000 TGFs are detected via satellite and ground-based sensors and only a small fraction are geolocated via sferics.

To date, few studies have focused on individual thunderstorms and climates that produce TGFs. This dissertation examines TGFs from two differing data samples: 1) NASA's Fermi Gamma-Ray Burst Monitor (2013-2018) and 2) The TGF and …

Dry-Land Farming, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Dry-land farming is a system of land use, crop management, and timing of operations that are designed to cope with the conditions of climate and rainfall of a semiarid land. Experiments began on dry-land techniques as early as the 1860s and the methods became well-known in the Great Plains by the end of the 1880s. A major component of dry farming, which is a term (along with dry-land farming) of western American origin, is the conservation of soil moisture during dry weather by special methods of tillage and plant adaptation. It is not farming without moisture, but farming where moisture …

Reasons For Vacating The Land, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

According to interview data, the mid droughts began very early. The first was in 1908 and 1909 followed by a low rainfall period of 1910 and 1911. These mild droughts were followed by another dry period in 1925 and 1926 and later by the dust bowl period of the mid-1930s. To experience even a mild drought was sufficient to weed out the land speculators who had little interest in farming the land. There were also a number of people who intended to farm, but arrived with insufficient funds to purchase the necessary equipment to produce enough surplus to ride through …

Subdividing The Public Lands: The Apportionment And Settlement Of Northeast New Mexico, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

The land of northeastern New Mexico, outside of the recognized title rights of the former Mexican citizens, became the public domain of the United States by the treaty of Guadalupe Hidalgo in 1848. This immediately allowed for US control over 10,000 square miles of land within the area east of the 105° meridian and north of a line roughly defined by Interstate 40 in Quay County and the boundary between San Miguel and Guadalupe counties. Portions of the northeast which were excluded from this public domain by the action of the Court of Private Land Claims between 1891 and 1904 …

Peopling The Northeast Plains, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

During the 1880s and the early part of the 1890s the cattle companies were continuing to hire ranch hands to prove up homesteads around water holes. At the same time the early farmers began to appear in the northeast, but not in the form of the sodbusters who were to later swarm over the highland llanos during the early part of the twentieth century. The early farmers were not labeled "nesters," which was the derogatory term coined by the stockmen for the people who turned small parcels of the grassland into fields and began erecting fences over the plains. The …

Natural Elements Of Northeastern New Mexico, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Northeastern New Mexico is one of the most diverse natural landscapes in the state. Large volcanic vents dot the basalt flows that cap the piedmont surface, providing a very rugged horizon rather than the flat monotonous topography usually associated with the Great Plains of the United States. The dissected and rolling plains are broken by severely eroded canyons that have cut through the sandstone layers topped with caliche. In some areas where the major drainages confluence (such as the intersection of the Ute and Canadian or the Conchas and the Canadian) the narrow canyons broaden into extensive valleys characterized by …

Missouri Avenue On The Caprock, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Lured by reports about grama grass that was so high it tickled the belly of a horse, the settlers poured onto the high plains of New Mexico during the first decade of the twentieth century. Boom towns began to sprout up along the sidings that the single-line railroads needed for intersecting trains and for locating maintenance crews. The towns especially blossomed if the siding was next to a highland area of prairie that appeared capable of dryland farming. The railroad companies, which were provided with large blocks of land to promote settlement, and the merchants of the new railroad towns …

Interviews With Pioneers, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

There are many first-generation pioneers still living in northeastern New Mexico. Most are over eighty years of age and several are nearing the century mark. Their recall of the era of farming is remarkable and it is fascinating to record the events which are firmly locked into their minds. Many decades have passed since their families abandoned the farm and the homestead and either migrated to urban areas for employment or remained on the land by converting to a cattle economy. When probed or reminded of events through the line of questioning, most interviewees would discourse with clear details and …

Homesteading And Public Land Law, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

It is important to the discussion of Butcher and Wyatt as homesteaders to understand the public land laws which affected their choice of land. Consequently, a review of the history of land legislation affecting the allocation and use of the public domain is in order and particularly that legislation under which Butcher and Wyatt made entry: the Homestead Act of 1862. Through this act early settlers around Tucumcari were able to acquire, at little expense, 160 acre tracts of land. In addition, the shortcomings and beneficial aspects of other acts of Congress concerning the acquisition of public domain will be …

Elements To Assist The Farmers And Promote Immigration, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

The purpose of this portion of the resource survey of the northeastern plains is to reconstruct the settlement phase which occurred between 1880 and 1940, the period generally referred to as the homesteading era. To reconstruct the 60 years of human settlement and resettlement required an extensive review of secondary information resources as well as a field project(?) oriented around the collection of data from primary information resources. Much of the information that was compiled was directed toward a mapping project of the northeastern plains which included the location of the places named by the settlers as well as identifying …

Backyard Wildlife Refuges In Albuquerque, Nm: An Urban Land Ethic In Practice, Laurel E. Ladwig

Geography ETDs

In the urban setting, biodiversity conservation requires intentionally creating spaces humans and wildlife can share. An urban land ethic can guide this process. Developing and practicing this ethic requires asking questions that consider approaches from multiple disciplines and avoid anthropocentric framing. Both More-Than-Human and Critical Physical Geography bring multiple knowledges into conversation to make complex realities visible. This project explores these fields of scholarship as guides for reconciling the needs of the land community.

Sharing familiar spaces creates opportunities for developing ethical relationships between humans, non-humans, and natural systems. Wildlife gardening creates habitat in our residential and community areas, providing …

Learning Set Representations For Lwir In-Scene Atmospheric Compensation, Nicholas M. Westing, Kevin C. Gross, Brett J. Borghetti, Jacob A. Martin, Joseph Meola

Faculty Publications

Atmospheric compensation of long-wave infrared (LWIR) hyperspectral imagery is investigated in this article using set representations learned by a neural network. This approach relies on synthetic at-sensor radiance data derived from collected radiosondes and a diverse database of measured emissivity spectra sampled at a range of surface temperatures. The network loss function relies on LWIR radiative transfer equations to update model parameters. Atmospheric predictions are made on a set of diverse pixels extracted from the scene, without knowledge of blackbody pixels or pixel temperatures. The network architecture utilizes permutation-invariant layers to predict a set representation, similar to the work performed …

Unpacking The Process And Outcomes Of Ethical Markets: A Focus On Certified B Corporations, Renée Bogin Curtis

Dissertations and Theses

The growth in conscious consumption presents an opportunity to 1) better understand the potential outcomes of ethical market practices as a community-advocacy tool and 2) to consider potential policy considerations. The marketplace has increasingly become an arena for social action. This leads to the question of how can markets facilitate ethical business practices and community benefits? The recent rise of social benefit corporations warrants an evaluation of the outcomes of ethically-driven markets. Using a comparative research design and qualitative interview methods, this study examines certified Benefit Corporations (B Corps) in two selected cities: Philadelphia and Portland. Through interviews with B …
