Joint Co2 Mole Fraction And Flux Analysis Confirms Missing Processes In Casa Terrestrial Carbon Uptake Over North America, Sha Feng, Thomas Lauvaux, Christopher A. Williams, Kenneth J. Davis, Yu Zhou, Ian Baker, Zachary R. Barkley, Daniel Wesloh

Geography

Terrestrial biosphere models (TBMs) play a key role in the detection and attribution of carbon cycle processes at local to global scales and in projections of the coupled carbon-climate system. TBM evaluation commonly involves direct comparison to eddy-covariance flux measurements. We use atmospheric CO2 mole fraction ([CO2]) measured in situ from aircraft and tower, in addition to flux-measurements from summer 2016 to evaluate the Carnegie-Ames-Stanford-Approach (CASA) TBM. WRF-Chem is used to simulate [CO2] using biogenic CO2 fluxes from a CASA parameter-based ensemble and CarbonTracker version 2017 (CT2017) in addition to transport and CO2 boundary condition ensembles. The resulting “super ensemble” …

Extreme Heat Vulnerability And Spatial Accessibility To Cooling Centers In Connecticut, Nicholas Elton

Public Health Theses

Extreme heat is becoming an increasingly prevalent and prominent environmental health issue under climate change. The goal of this study is to evaluate heat vulnerability at the census tract level in the state of Connecticut and assess the spatial accessibility to cooling centers – an extreme heat intervention. A variety of environmental and sociodemographic variables related to heat and health were identified based on previous literature and used in a varimax-rotated principal component analysis to reduce dimensionality and identify key components that constitute a heat vulnerability score. In addition, cooling center locations were identified based on news media and a …

Female Pacific Walruses (Odobenus Rosmarus Divergens) Show Greater Partitioning Of Sea Ice Organic Carbon Than Males: Evidence From Ice Algae Trophic Markers, Chelsea W. Koch, Lee W. Cooper, Ryan J. Woodland, Jacqueline M. Grebmeier, Karen E. Frey, Raphaela Stimmelmayr, Cédric Magen, Thomas A. Brown

Geography

The expected reduction of ice algae with declining sea ice may prove to be detrimental to the Pacific Arctic ecosystem. Benthic organisms that rely on sea ice organic carbon (iPOC) sustain benthic predators such as the Pacific walrus (Odobenus rosmarus divergens). The ability to track the trophic transfer of iPOC is critical to understanding its value in the food web, but prior methods have lacked the required source specificity. We analyzed the H-Print index, based on biomarkers of ice algae versus phytoplankton contributions to organic carbon in marine predators, in Pacific walrus livers collected in 2012, 2014 and 2016 from …

Field-Scale Soil Moisture Bridges The Spatial-Scale Gap Between Drought Monitoring And Agricultural Yields, Noemi Vergopolan, Sitian Xiong, Lyndon Estes, Niko Wanders, Nathaniel W. Chaney, Eric F. Wood, Megan Konar, Kelly Caylor, Hylke E. Beck, Nicolas Gatti, Tom Evans, Justin Sheffield

Geography

Soil moisture is highly variable in space and time, and deficits (i.e., droughts) play an important role in modulating crop yields. Limited hydroclimate and yield data, however, hamper drought impact monitoring and assessment at the farm field scale. This study demonstrates the potential of using field-scale soil moisture simulations to support highresolution agricultural yield prediction and drought monitoring at the smallholder farm field scale. We present a multiscale modeling approach that combines HydroBlocks a physically based hyper-resolution land surface model (LSM) with machine learning. We used HydroBlocks to simulate root zone soil moisture and soil temperature in Zambia at 3 …

The Crisis Of Chad: Men’S Rights Movements And Contemporary Anti-Feminism, Kendrick Zapata

Dissertations and Theses

This thesis analyzes the relationship between the modern incel and manosphere movement, and its historical legacies in anti-feminist discourses in late 20th century men's rights movements. The manosphere is a collection of online videos, forums, blogs, and websites dedicated to raising awareness or promoting masculinist philosophies. Incels in particular are individuals that understand their lack of sexual interaction as inherent, and often interact in digital spaces with others. Incel beliefs range from calling for the reversal of women’s rights, to seeking advice on self-improvement forums that offer advice to young men seeking to improve their physique through diet and exercise. …

“Women Of Allah” And “The Book Of Kings:” Shirin Neshat’S Narratives Of Returning Home, Zahra Banyamerian

Dissertations and Theses

Using the framework of nostalgia defined by Svetlana Boym in The Future of Nostalgia, this thesis revisited the series “Women of Allah” and “The Book of Kings,” that Shirin Neshat created twenty years apart. It argues that the photographs of both series became the terrain through which Neshat narrates the relationship between her past, present, and future. She constructs her longing for home in “Women of Allah'' and she visualizes her homecoming in “The Book of Kings.” The central point to this research is Neshat’s personal relationship to an event that caused her a traumatic experience, the experience that interrupted …

Spatial And Non-Spatial Patterns Of Genetic Diversity In Neotropical Bats, Andrea J. Calderon Brito

Dissertations and Theses

Macroecological studies that predict genetic diversity and its correlation with other biodiversity dimensions are essential to conservation in a rapidly changing environment. However, in bats (order Chiroptera), studies associating abiotic or ecological traits that could help to predict genetic diversity are scarce, even for singular species. In the Neotropics, the highest concentration of mammal and amphibian genetic diversity has been found in the Andes mountains and the Amazon Rainforest, yet it is an open question whether bat genetic diversity is also higher in these regions, or even if any abiotic factors are correlated with bat genetic diversity. Additionally, it is …

China In Africa: Partner Or Exploiter? The Case Of Zambia, Chansa E. Mushota

Dissertations and Theses

Marked by investments, loans, and finance, China’s engagement in Africa has grown swiftly. Amongst sub-Saharan Africa’s many trading and developing partners, China remains the biggest partner and investor with an increase in trade relations.^[1] The China-Africa relationship has brought significant economic opportunities, but it has also generated controversy in the international community. China has been challenged by some of forming a partnership with African governments solely for China’s own interests. China provides low-interest loans to the African governments for development and infrastructure projects. However, China’s motives are exploitative as China uses economic and political pressures to influence African governments …

Reassessing The Ranging Behavior Of Black-And-White Ruffed Lemurs (Varecia Variegata) In Ranomafana National Park, Madagascar, Jelisa R. Oliveras

Dissertations and Theses

This study investigates black-and-white ruffed lemur (Varecia variegata) space use and movement using autocorrelated kernel density estimation (AKDE), a new methodology available from the continuous-time movement model (ctmm) package in R. Data were collected from 24 adults and subadults (10 males, 11 females, 3 subadult males) living in two adjacent V. variegata communities at Mangevo bush camp in Ranomafana National Park, Madagascar (RNP) for 11 months (February – December 2008) to estimate annual and seasonal patterns of individual and community-level range use. Autocorrelated kernel density estimates generated in this study are compared to earlier kernel density estimates from …

'Awakening The Sleeping Giant': Re-Indigenization Principles For Transforming Biodiversity Conservation In Canada And Beyond, M’S-It No’Kmaq, Albert Marshall, Karen F. Beazley, Jessica Hum, Shalan Joudry, Anastasia Papadopoulos, Sherry Pictou, Janet Rabesca, Lisa Young, Melanie Zurba

Articles, Book Chapters, & Popular Press

Precipitous declines in biodiversity threaten planetary boundaries, requiring transformative changes to conservation. Colonial systems have decimated species and ecosystems and dispossessed Indigenous Peoples of their rights, territories, and livelihoods. Despite these challenges, Indigenous governed lands retain a large proportion of biodiversity-rich landscapes. Indigenous Peoples have stewarded the land in ways that support people and nature in respectful relationship. Biodiversity conservation and resurgence of Indigenous autonomies are mutually compatible aims. To work towards these aims requires significant transformation in conservation and re-Indigenization. Key to both are systems that value people and nature in all their diversity and relationships. This paper introduces …

Resource Curse In Kenya’S Coastal Region: A Symptom Of Institutional Failure, George Atisa

Public Affairs and Security Studies Faculty Publications

Regions endowed with abundant natural resources are expected to thrive economically, but this is not the case for Kenya’s coastal region. Communities in this region believe they are working hard enough but are still held in abject poverty by circumstances not of their own making. This state of development raises one pertinent question – who is responsible for this poor state of development and rampant poverty? When it is about an individual, it is easy to attach success to talent and hard work, and sometimes sheer luck, but it is difficult to generalize the “hard-working” argument to an entire community …

Assessment Of The Gut Bacterial Microbiome And Metabolome Of Girls And Women With Rett Syndrome, Santosh Thapa, Alamelu Venkatachalam, Nabeel Khan, Mohammed Naqvi, Miriam Balderas, Jessica K Runge, Anthony Haag, Kathleen M Hoch, Daniel G Glaze, Ruth Ann Luna, Kathleen J Motil

Children’s Nutrition Research Center Staff Publications

Background: Gastrointestinal problems affect the health and quality of life of individuals with Rett syndrome (RTT) and pose a medical hardship for their caregivers. We hypothesized that the variability in the RTT phenotype contributes to the dysbiosis of the gut microbiome and metabolome in RTT, predisposing these individuals to gastrointestinal dysfunction.

Objectives: We characterized the gut bacterial microbiome and metabolome in girls and young women with RTT (n = 44) and unaffected controls (n = 21), and examined the relation between the composition of the microbiome and variations in the RTT phenotype.

Methods: Demographics and clinical information, including growth and …

Gut Microbiota Profiles Of Young South Indian Children: Child Sex-Specific Relations With Growth, Nirupama Shivakumar, Ambily Sivadas, Sarita Devi, Farook Jahoor, John Mclaughlin, Craig P Smith, Anura V Kurpad, Arpita Mukhopadhyay

Children’s Nutrition Research Center Staff Publications

Gut microbiota has been implicated as a modifier of childhood growth. Here, 16S rRNA sequencing-based fecal microbiota profiles of 18-24 month old Indian children were evaluated (n = 41), in relation to their anthropometric parameters, intestinal permeability, body composition and total energy expenditure. Pathway analyses were conducted to assess microbial functions related to stunting, underweight and wasting. The fecal microbiota was enriched in Prevotella 9, Bifidobacterium and Escherichia-Shigella. Weight, weight-for-age Z-scores (WAZ) and weight-for-length Z-scores (WLZ), along with age, acted as covariates of microbiota variation specifically in boys (n = 23). Bifidobacterium longum subsp longum abundance was positively associated with …

Inter- And Intra-Annual Effects Of Lethal Removal On Common Raven Abundance In Nevada And California, Usa, Shawn T. O'Neil, Peter S. Coates, Julia C. Brockman, Pat J. Jackson, Jack O. Spencer Jr., Perry J. Williams

Human–Wildlife Interactions

Populations of common ravens (Corvus corax; ravens) have increased rapidly within sagebrush (Artemisia spp.) ecosystems between 1960 and 2020. Although ravens are native to North America, their population densities have expanded to levels that negatively influence the population dynamics of other wildlife species of conservation concern, such as greater sage-grouse (Centrocercus urophasianus) and desert tortoises (Gopherus agassizii). For this reason, lethal removal, such as the application of the avicide DRC-1339, has been used to manage raven numbers at local scales and under certain circumstances. Because the relative effectiveness of DRC-1339 in reducing raven …

Smart: A Science-Based Tiered Framework For Common Ravens, Seth J. Dettenmaier, Peter S. Coates, Cali L. Roth, Sarah C. Webster, Shawn T. O'Neil, Kerry L. Holcomb, John C. Tull, Pat J. Jackson

Human–Wildlife Interactions

Large-scale increases and expansion of common raven (Corvus corax; raven) populations are occurring across much of North America, leading to increased negative consequences for livestock and agriculture, human health and safety, and sensitive species conservation. We describe a science-based adaptive management framework that incorporates recent quantitative analyses and mapping products for addressing areas with elevated raven numbers and minimizing potential adverse impacts to sensitive species, agricultural damage, and human safety. The framework comprises 5 steps: (1) desktop analysis; (2) field assessments; (3) comparison of raven density estimates to an ecological threshold (in terms of either density or density …

Guest Editorial: Disaster, State And Science: Historical Narratives Of Extreme Weather In East Asia And The Pacific, Fiona Williamson

Research Collection School of Social Sciences

This curated special issue asks how history can be used as a lens into disaster and disaster management. It takes as its premise the idea that approaches from different disciplines - including the humanities and social sciences – can offer new perspectives on understanding disaster, managing disaster and disaster risk. The concept is not new, historically focussed studies have long provided meat for hazard investigations and modelling, especially those focused on geological or hydrological time-series analyses; multi-hazard interactions and identifying historical underliers for contemporary risk. It has become increasingly common, for example, to include historians in collaborative efforts to better …

Geoprivacy, Convenience, And The Pursuit Of Anonymity In Digital Cities, Jerome Dobson, William A. Herbert

Publications and Research

Cities demand spatial efficiencies that can be achieved only through sharing of information. Current technologies support collection, processing, and dissemination of unprecedented quantities of personal, public, and corporate information. Inherent in this milieu is an inevitable contest among societal efficiency, corporate profits, consumer convenience, personal privacy, and even freedom. The authors examine current trends in technology, data collection, legislation, and public acceptance. They find that without broad specific regulations limiting location data collection and use—including a universal protected right for individuals to pursue anonymity—governments, commercial enterprises, employers, and individuals increasingly will exploit tracking technologies at the expense of geoprivacy.

The Relationship Between Neighborhood Characteristics And Homicide In Karachi, Pakistan, Salma Hamza, Imran Khan, Linlin Lu, Hua Liu, Farkhunda Burke, Syed Nawaz-Ul-Huda, Muhammad Fahad Baqa, Aqil Tariq

Political Science & Geography Faculty Publications

The geographical concentration of criminal violence is closely associated with the social, demographic, and economic structural characteristics of neighborhoods. However, few studies have investigated homicide patterns and their relationships with neighborhoods in South Asian cities. In this study, the spatial and temporal patterns of homicide incidences in Karachi from 2009 to 2018 were analyzed using the local indicators of spatial association (LISA) method. Generalized linear modeling (GLM) and geographically weighted Poisson regression (GWPR) methods were implemented to examine the relationship between influential factors and the number of homicides during the 2009–2018 period. The results demonstrate that the homicide hotspot or …

Weather-Related Carbon Monoxide Poisoning In The United States: 2000-2019, Bailey Raine Stevens

Graduate Research Theses & Dissertations

Carbon monoxide (CO) is a colorless, odorless gas that can cause injury or death if inhaled. CO is a frequent secondary hazard induced by the aftereffects of natural hazards as individuals, families, and communities will often seek alternative power sources for heating, cooking, lighting, and cleanup during the emergency and recovery phases of a disaster. These alternative power sources – such as generators, petrol heaters, and vehicles, exhaust CO – can ultimately build to toxic levels in enclosed areas. Ever-increasing environmental and societal changes combined with an aging infrastructure are increasing the odds of power failures during hazardous weather events, …

Quantifying The Effects Of Early Competition On Niche Specialization: A Natural Experiment In A Restored System, Christy Nicole Wails

Graduate Research Theses & Dissertations

Islands support the greatest numbers of endemic species but are highly vulnerable to human activities. In particular, the introduction of invasive, predatory mammals (e.g., rodents) has resulted in sharp declines of island fauna due to a lack of evolved behavioral capacities to avoid depredation. Because of this, invasive species are considered to be one of the most detrimental impacts to biodiversity. To combat this biodiversity loss, the eradication of invasive mammals is now a primary conservation tool, with > 700 attempts globally. However, mammal eradications are predicated on the assumption that islands will naturally return to their pre-invaded condition. Yet many …

Closing The Opportunity Gap In The Advanced Placement Program, Julie H. Lam

Graduate Research Theses & Dissertations

The Advanced Placement (AP) Program has become ubiquitous in terms of earning college credit during high school. Since the College Board incorporated it in 1956, the AP Program has grown to include 38 courses across seven subjects/categories. Recently, approximately half the states have passed legislation guaranteeing credit towards an undergraduate degree contingent on passing AP Exam scores. Many studies, especially those from the College Board, have shown that students who pass AP exams are more likely to succeed in other academic areas, including earning higher undergraduate GPAs and graduating with an undergraduate degree in less time. With the opportunities and …

Remote Sensing Applications In Population Estimation, Regression Analysis, And Urban Growth Simulation Modeling For A Middle Eastern City, Elaf Amer Alyasiri

Graduate Research Theses & Dissertations

Due to a change in government regime and population migration, the City of Hillah in Iraq has been facing several urban issues, particularly population estimating and urban growth planning. Since the last census conducted in 1997, population in Iraq has been estimated based on the annual growth, without considering migration as factor of the population growth. Therefore, the aim of this dissertation study was to develop a population estimation method and an urban growth simulation method for the City of Hillah. Population data were estimated for Hillah, using the Normalized Difference Built-up Index (NDBI) derived from Remote Sensing (RS) and …

Sea Level Rise Impacts On The City Of Cape Coral, Southwest Florida From 2020 To 2050, Jawata Afnan Saba

Electronic Theses and Dissertations

Sea level rise, a consequence of global climate change, has been affecting the U.S. coasts with flooding and exacerbated storm surges. Florida is highly vulnerable because it has low-lying topography and coastlines on both the Atlantic Ocean and the Gulf of Mexico. The City of Cape Coral, Southwest Florida, is known as a ‘waterfront wonderland’ with 400 miles of canals that provide waterfront property to the residents. Most of the canals are navigable, and many have access to the Gulf of Mexico. The city is vulnerable to sea level rise because of its canals, site between the Matlacha Pass and …

Quantification Of Climate Variability And Extreme Events In The Great Plains, Angelinah Ntsieng Rasoeu

Electronic Theses and Dissertations

Climate variability and extreme events continue to worsen resulting in significant impacts to society and the environment. Quantifying precipitation variability, streamflow, and extreme events at local scale is crucial for local planning and management due to spatial and temporal precipitation variability which influences streamflow and thus, water resources. This study uses statistical tools to analyze 1895-2019 (125 years) of historical precipitation data to examine how long-term precipitation varies annually, seasonally, and monthly, and create climate classifications. The results show that annual precipitation is increasing linearly over time ranging from 13.2 in (1976) to 43.1 in (2010) and 5 climate classes …

Investigating How Qipao And Hanfu Dresses Are Representative Of China, Jennifer Tibberts

Senior Honors Theses

This research investigates why hanfu and qipao represent the nation of China. Previous sources have described the dresses, Chinese history, and Chinese fashion aesthetics, and have questioned why many people wear these dresses today. However, previous studies have not investigated what aspects of hanfu and qipao make both Chinese people and outsiders associate these dresses so strongly with China. This research looks deeply into the importance of fashion to expression of identity, characteristics and ideals of Chinese clothing, what hanfu and qipao are, how the dresses connect with Chinese history and traditions, and why the styles have phased in and …

Cultural Intelligence Development And Study Abroad: The Effect Of Destination, Luke Zirkle

Senior Honors Theses

Cultural intelligence (CQ) is an emerging field in a globalized world. As the world becomes increasingly interconnected, study abroad opportunities at higher educational institutions have become widely-accepted means for developing students’ CQ. While a number of variables seem to impact CQ development through study abroad programs, one variable seems as yet to have been largely unexplored. This research examines anonymous archival data from juniors in Liberty University’s Global Studies program during the spring semesters of 2016, 2017, 2018, and 2019 to observe a potential pattern that suggests the role of a study abroad host-culture on the student’s CQ development. Though …
