Heuristic Approaches For Near-Optimal Placement Of Gps-Based Multi-Static Radar Receivers In American Coastal Waters, Brandon J. Hufstetler

Theses and Dissertations

Narcotics smuggling across the Caribbean Sea is a growing concern for the United States Coast Guard. One vector for this illicit trafficking is via small aircraft. This thesis proposes a multi-static radar architecture using the Global Positioning System (GPS) constellation as a transmission source to detect these aircraft as they transit a detection fence. The system developed in this thesis relies on the forward-scatter phenomenon in which a radar shadow is cast by a target as it crosses in front of a transmitter, creating a measurable difference in the signal amplitude at the receiver. This thesis first develops a mathematical …

Analysis And Forecasting Of The 360th Air Force Recruiting Group Goal Distribution, Tyler Spangler

Theses and Dissertations

This research utilizes monthly data from 2012-2017 to determine economic or demographic factors that significantly contribute to increased goaling and production potential in areas of the 360th Recruiting Groups. Using regression analysis, a model of recruiting goals and production is built to identify squadrons within the 360 RCGs zone that are capable of producing more or fewer recruits and the factors that contribute to this increased or decreased capability. This research identifies that a zones high school graduation rate, the number of recruiters, and the number of JROTC detachments in a zone are positively correlated with recruiting goals and that …

Visual Exploration Of Utah Trajectory Data And Their Applications In Transportation, Seth Miller, Zachary Vander Laan, Yinhu Wang, Nikola Markovic

TREC Final Reports

Transportation agencies have an opportunity to leverage massive GPS trajectory data to support their analyses and enhance their decision making. However, these data are typically purchased from vendors, which means that transportation agencies must understand their benefits before they decide to invest in data acquisition. To help transportation agencies better understand the tremendous value of trajectory data, the PI of the project acquired Utah GPS trajectory data from one of the leading GPS data providers and conducted visual analyses demonstrating applications of trajectory data in various areas of transportation. The analyses focused on (a) evaluating the data itself by exploring …

The Digital Subversion Of Urban Space: Power, Performance And Grime, Orlando Woods

Research Collection School of Social Sciences

Digital technologies play an increasingly prominent role in the reproduction of society and space. Rather than being studied as a separate category of understanding, the ways in which such technologies intersect with and inflect upon the real world has provided a recent focus of research. Urban music is inherently spatial, but the ways in which digital technologies have enabled artists to resist injustice, to reproduce space and to reclaim the right to the city has not yet been considered. This article fills the lacuna by exploring how grime artists harness digital technologies to resist marginalization by the mainstream and create …

Estimation Of Fixed Effects Spatial Dynamic Panel Data Models With Small T And Unknown Heteroskedasticity, Liyao Li, Zhenlin Yang

Research Collection School Of Economics

We consider the estimation and inference of fixed effects (FE) spatial dynamic panel data (SDPD) models under small T and unknown heteroskedasticity by extending the M-estimation strategy for homoskedastic FE-SDPD model of Yang (2018, Journal of Econometrics). Unbiased estimating equations are obtained by adjusting the conditional quasi-score functions given the initial observations, leading to M-estimators that are free from the initial conditions and robust against unknown cross-sectional heteroskedasticity. Consistency and asymptotic normality of the proposed M-estimator are established. The standard errors are obtained by representing the estimating equations as sums of martingale differences. Monte Carlo results show that the proposed …

Common Power Laws For Cities And Spatial Fractal Structures, Tomoya Mori, Tony E. Smith, Wen-Tai Hsu

Research Collection School Of Economics

City-size distributions are known to be well approximated by power laws across a wide range of countries. But such distributions are also meaningful at other spatial scales, such as within certain regions of a country. Using data from China, France, Germany, India, Japan, and the United States, we first document that large cities are significantly more spaced out than would be expected by chance alone. We next construct spatial hierarchies for countries by first partitioning geographic space using a given number of their largest cities as cell centers and then continuing this partitioning procedure within each cell recursively. We find …

Welfare Consequences Of Access To Health Insurance For Rural Households: Evidence From The New Cooperative Medical Scheme In China, Jessica Ya Sun

Research Collection School Of Economics

This study evaluates the welfare benefits of the New Cooperative Medical Scheme (NCMS), the main public health insurance plan for the rural population in China. The findings show that the value of the NCMS to recipients is slightly lower than the government's costs of implementation, ranging from 0.79 to 0.97 per RMB of the resource cost of the NCMS. The estimated moral hazard costs are low compared with the total benefits. It is also estimated that the benefits originating from the NCMS's insurance function only constitute 20% of the total benefits, suggesting a need for higher generosity levels among rural …

Is It Possible To Discern Striga Weed (Striga Hermonthica) Infestation Levels In Maize Agro-Ecological Systems Using In-Situ Spectroscopy?, Bester Tawona Mudereri, Timothy Dube, Saliou Niassy, Emily Kimathi, Tobias Landmann, Zeyaur Khan, Elfatih M. Abdel-Rahman

All Peer-Reviewed Publications

The invasion by Striga in most cereal crop fields in Africa has posed a significant threat to food security and has caused substantial socioeconomic losses. Hyperspectral remote sensing is an effective means to discriminate plant species, providing possibilities to track such weed invasions and improve precision agriculture. However, essential baseline information using remotely sensed data is missing, specifically for the Striga weed in Africa. In this study, we investigated the spectral uniqueness of Striga compared to other co-occurring maize crops and weeds. We used the in-situ FieldSpec® Handheld 2™ analytical spectral device (ASD), hyperspectral data and their respective narrow-band indices …

Predicting The Spatial Suitability Distribution Of Moringa Oleifera Cultivation Using Analytical Hierarchical Process Modelling, T. Tshabalala, B. Ncube, H. P. Moyo, E. M. Abdel-Rahman, O. Mutanga, A. R. Ndhlala

Moringa oleifera Lam, often grows well under cultivation in the tropics and sub-tropics. It does well in sandy to clayey soils and tolerates low rainfall. The plant is well-known for its nutritional and medicinal properties, hence it is fast gaining popularity in South Africa and the rest of the world. The objective of this study was to predict the suitable areas for cultivating M. oleifera in South Africa using climate and edaphic variables that significantly affect its growth and development. We used an Analytical Hierarchical Process (AHP) and Geographic Information System (GIS) weight function to assign suitability weights to criteria …

Marriage Migrants’ Use Of Social Media, Soontae An, Sun Sun Lim, Hannah Lee

Research Collection College of Integrative Studies

This study analyzed the role and impact of social media use on the daily lives of marriage migrants. We empirically examined a moderated mediation model by surveying 201 marriage migrants. This study focused on four key concepts: social stigma, empowerment, self-stigma, and social networks forged via social media such as Facebook, Kakao Talk, LINE, and Viber. The results confirmed that the detrimental effect of social stigma can be mitigated by robust social networks, and a greater feeling of empowerment resulted in less self-stigma. Consequently, social networks through social media acted as a buffer against negative public opinion or any belittling …

Assessing And Expanding The Evidence Base For Project Echo And Echo-Like Models: Findings Of A Technical Expert Panel., Laura J Faherty, Adam J Rose, Andre Chappel, Caroline Taplin, Monique Martineau, Shira H Fischer

Project ECHO Bibliography

BACKGROUND: In 2003, Project ECHO (Extension for Community Healthcare Outcomes) began using technology-enabled collaborative models of care to help general practitioners in rural settings manage hepatitis C. Today, ECHO and ECHO-like models (EELM) have been applied to a variety of settings and health conditions, but the evidence base underlying EELM is thin, despite widespread enthusiasm for the model.

METHODS: In April 2018, a technical expert panel (TEP) meeting was convened to assess the current evidence base for EELM and identify ways to strengthen it.

RESULTS: TEP members identified four strategies for future implementors and evaluators of EELM to address key …

Thirty Years Of Religious Freedom In Russia: The Case Of Ekaterinburg, Elena Glavatskaya

Occasional Papers on Religion in Eastern Europe

"The religious revival, which began nationwide during the USSR’s last decade, affected all religious denominations, including the so-called “traditional” religions, which had deep roots in Imperial Russia’s history, and new religions that appeared after the collapse of Soviet ideology. The religious renaissance manifested itself through the rapidly increasing number of religious communities, religion’s fast penetration into social and political life, and the church buildings that mushroomed all over the country. This article focuses on the history of the religious landscape in Russia since 1989, using the city of Ekaterinburg as a case study. We use the religious landscape concept to …

'Converted Co-Ethnics': Romanian Migrants In The Northern Serbian Province Of Vojvodina, Aleksandra Djurić-Milovanović

Occasional Papers on Religion in Eastern Europe

In this paper, my case study highlights Romanian neo-Protestant migrants from Serbia who either returned to their “home country,” or work on different missionary activities among their co-ethnics after the fall of communism. To a large degree, members of the Romanian minority in Serbia belong to the Romanian Orthodox Church, which is the dominant confession, then a smaller number to the Romanian Greek-Catholic church and various neo-Protestant communities, such as the Nazarene, the Adventist, the Baptist, and the Pentecostal community. Starting from the hypothesis that the conversion of the Romanians in Serbia to neo-Protestantism is closely related to issues of …

Hydrosocial Hinterlands: An Urban Political Ecology Of Southern California’S Hydrosocial Territory, Alida Cantor

Geography Faculty Publications and Presentations

Urban political ecology (UPE) has conceptualized the city as a process of urbanization rather than a bounded site. Yet, in practice, the majority of UPE literature has focused on sites within city limits. This tension in UPE evokes broader conversations in urban geography around city-as- place versus urbanization-as-process. In this paper, I bring a UPE analysis to examine co- constitutive urbanization and ruralization processes, focusing on sites beyond city boundaries in three empirical case studies located within the broader hydrosocial territory of urban Southern California. By focusing on the rural components of hydrosocial territories, I show that each of the …

Soil And Water Conservation And Integrated Management In Watershed Ecosystem Of The Loess Plateau, China, Guobin Liu, Gaolin Wu, Guoliang Wang, David Mitchell

IGC Proceedings (1977-2023)

The Loess Plateau is well known for severe soil erosion and ecosystem degradation. The key issues in this region are the food security (grain), ecological security and a sustainable economy. This paper reviews a range of studies on ecological restoration, and management and the benefit at watershed scale on the Loess Plateau. This includes several successful cases and failures in soil conservation. The paper presents practical soil conservation measures and related benefit analysis, and discusses some effective methods adopted in soil erosion control, research directions and future perspectives for the Loess Plateau.

The Musical Poetics Of Witness: Two Anthropocene Journeys, Heidi Hart

Yale Journal of Music & Religion

Kerstin Ekman’s The Forest of Hours (first published in Swedish in 1988) and Jenny Erpenbeck’s Visitation(published in German as Heimsuchung in 2008) span two decades and two countries, but both novels reach across far larger epochs, in their respective journeys from Europe’s glacial prehistory through the Dark Ages and the Thirty Years War, and through the twentieth century’s collective trauma. Though disagreement persists on when the Anthropocene began to leave its mark in stone, contemporary fiction often registers its traces through a marginally human witness who somehow survives generation after generation, recording in word or action what he or …

Geographic Life History Differences Predict Genomic Divergence Better Than Mitochondrial Barcodes Or Phenotype, Daniel P. Duran, Robert A. Laroche, Harlan M. Gough, Rodger A. Gwiazdowski, Charles B. Knisley, David P. Herrmann, Stephen J. Roman, Scott P. Egan

School of Earth & Environment Departmental Research

Species diversity can be inferred using multiple data types, however, results based on genetic data can be at odds with patterns of phenotypic variation. Tiger beetles of the Cicindelidia politula (LeConte, 1875) species complex have been taxonomically problematic due to extreme phenotypic variation within and between populations. To better understand the biology and taxonomy of this group, we used mtDNA genealogies and multilocus nuclear analyses of 34,921 SNPs to elucidate its evolutionary history and evaluate the validity of phenotypically circumscribed species and subspecies. Genetic analyses recovered two divergent species that are also ecologically distinct, based on adult life history. These …

Assessing Boreal Peat Fire Severity And Vulnerability Of Peatlands To Early Season Wildland Fire, Laura Bourgeau-Chavez, Sarah L. Grelik, Michael Billmire, Liza K. Jenkins, Eric S. Kasischke, Merritt R. Turetsky

Michigan Tech Publications, Part 1

Globally peatlands store large amounts of carbon belowground with 80% distributed in boreal regions of the northern hemisphere. Climate warming and drying of the boreal region has been documented as affecting fire regimes, with increased fire frequency, severity and extent. While much research is dedicated to assessing changes in boreal uplands, few research efforts are focused on the vulnerability of boreal peatlands to wildfire. In this case study, an integration of field data collection, land cover mapping of peatland types and Landsat-based fire severity mapping was conducted for four early season (May to mid-June) wildfires where peatlands are abundant in …

Female Genital Mutilation/Cutting In Senegal: Is The Practice Declining? Descriptive Analysis Of Demographic And Health Surveys, 2005–2017, Dennis Matanda, Glory Atilola, Zhuzhi Moore, Paul Komba, Lubanzadio Mavatikua, Chibuzor Christopher Nnanatu, Ngianga-Bakwin Kandala

Reproductive Health

To achieve the Sustainable Development Goals, female genital mutilation/cutting (FGM/C) is one of the most prominent issues world leaders and governments must address. In Senegal, estimates from the 2017 Senegal Demographic and Health Survey show that almost a quarter of women aged 15–49 have undergone FGM/C, while 14 percent of girls aged 0–14 years have been cut. Given the many interventions that have been implemented in Senegal with the intention of scaling down FGM/C rates, the key question is: To what extent has the practice declined? The aim of this study, as presented in this working paper, was to generate …
