Traffic Congestion In F.C.T: Demand And Supply Approach, Ibrahim Abdul, Salihu Habibu Mohammed Gani, Ibrahim G. Umaru

Bullion

This study examined traffic congestion in Abuja metropolis, F.C.T.- Nigeria using demand and supply approach. The study adopted survey research design. Primary data was collected using questionnaires. Descriptive statistics was used to analysed the data with the aid of tables and graphs. It was discovered that as a road reaches its capacity, each additional vehicle imposes more total delay on others than they bear, resulting in excessive traffic volumes. Congestion is mainly due to the intensive use of automobiles, whose ownership has spread massively in the F.C.T. in recent decades. The study revealed that traffic congestion causes serious consequences in …

Effectiveness, Equity, And Ethics Of Costa Rica's Payment For Environmental Services Program., Anna J Carter

College of Arts & Sciences Senior Theses

This paper examines the effectiveness of Costa Rica’s Payments for Environmental Services, or PSA program, which provides government subsidies to participants who protect forested lands or reforest their land. Effectiveness is determined in terms of the program’s progress in reversing deforestation and generating reforestation efforts, with particular attention paid to the success and failings of the program in reaching small landowners. The claim that the PSA program can act as a tool for human development is evaluated through its accessibility to small landowners. Finally, the ethical costs and benefits of the market based scheme underlying the PSA program as a …

Modeling Quality Of Urban Life Using A Geospatial Approach, Helena Merschdorf, Michael E. Hodgson, Thomas Blaschke

Faculty Publications

The rapid global urbanization of the past century poses several challenges for planners and policy makers. In particular, the conflation of social and urban issues must be understood to create sustainable and livable urban places. In this regard, it was our aim to model and understand the relationship between urban characteristics and peoples’ perceived quality of urban life (QoUL) using statistical analysis and geospatial modeling. We selected objective variables representing urban characteristics based on literature and used principal components analysis to develop uncorrelated components. These components served as the independent variables in a multiple linear regression analysis. The subjective, dependent …

The Algorithmic Divide And Equality In The Age Of Artificial Intelligence, Peter K. Yu

Faculty Scholarship

In the age of artificial intelligence, highly sophisticated algorithms have been deployed to provide analysis, detect patterns, optimize solutions, accelerate operations, facilitate self-learning, minimize human errors and biases and foster improvements in technological products and services. Notwithstanding these tremendous benefits, algorithms and intelligent machines do not provide equal benefits to all. Just as the digital divide has separated those with access to the Internet, information technology and digital content from those without, an emerging and ever-widening algorithmic divide now threatens to take away the many political, social, economic, cultural, educational and career opportunities provided by machine learning and artificial intelligence. …

A Gendered Analysis Of The Ready-Made Garments (Rmg) Sector Of Bangladesh: A Paradox Of Empowerment And Dis-Empowerment, Ishma Fairooz Iqbal

College of Liberal Arts & Social Sciences Theses and Dissertations

Neoliberal globalization is a gendered process. Transnational production in its search for “cheap, docile, and dexterous” labor has led to the expansion of the Bangladeshi export-led garment industry, which in turn has resulted in the feminization of labor. While the increase in number of poor women workers entering the formal economy of Bangladesh may give the impression of empowerment, I argue that the disadvantages associated with employment in the garments sector creates a paradox of empowerment and dis-empowerment. Does economic opportunity inevitably lead to the empowerment of all women? In this thesis I will examine the gendered processes of neoliberal …

Metal Content Of Stream Sediments As A Tool To Assess Remediation In An Area Recovering From Historic Mining Contamination, Mélida Gutiérrez, Xiaomin Qiu, Zachary J. Collette, Zachary T. Lurvey

College of Natural and Applied Sciences

Lead and zinc mining was booming in the early 1900s in and near Joplin, Missouri; a town within the Tri-State Mining District, USA. After the ore became depleted, mining companies moved out, leaving a profoundly disturbed land. Presently, over 90% of the land has been remediated. We collected sediment samples along two creeks flowing through the historically contaminated area that have been identified as major contributors of metals to downstream reservoirs, Center Creek (14 samples) and Turkey Creek (30 samples). Sediment metal content was determined by aqua regia extraction, the potentially bioavailable fraction by 0.11 M acetic acid extraction, and …

Sumoylation In Human Pathogenic Fungi: Role In Physiology And Virulence, Mahima Sagar Sahu, Sandip Patra, Kundan Kumar, Rupinder Kaur

Open Access archive

The small ubiquitin-related modifier (SUMO) protein is an important component of the post-translational protein modification systems in eukaryotic cells. It is known to modify hundreds of proteins involved in diverse cellular processes, ranging from nuclear pore dynamics to signal transduction pathways. Owing to its reversible nature, the SUMO-conjugation of proteins (SUMOylation) holds a prominent place among mechanisms that regulate the functions of a wide array of cellular proteins. The dysfunctional SUMOylation system has been associated with many human diseases, including neurodegenerative and autoimmune disorders. Furthermore, the non-pathogenic yeast Saccharomyces cerevisiae has served as an excellent model to advance our understanding …

Anti-Stress, Glial-And Neuro-Differentiation Potential Of Resveratrol: Characterization By Cellular, Biochemical And Imaging Assays, Sajal Afzal, Sukant Garg, Divya Adiga, Yoshiyuki Ishida

Open Access archive

Environmental stress, exhaustive industrialization and the use of chemicals in our daily lives contribute to increasing incidence of cancer and other pathologies. Although the cancer treatment has revolutionized in last 2–3 decades, shortcomings such as (i) extremely high cost of treatment, (ii) poor availability of drugs, (iii) severe side effects and (iv) emergence of drug resistance have prioritized the need of developing alternate natural, economic and welfare (NEW) therapeutics reagents. Identification and characterization of such anti-stress NEW drugs that not only limit the growth of cancer cells but also reprogram them to perform their specific functions are highly desired. We …

Honoring A Giant: Immanuel Wallerstein And His Contributions To Social Sciences, Vladimir Alalykin-Izvekov

Comparative Civilizations Review

As a salute to a preeminent social scholar of our times, Immanuel M. Wallerstein (1930-2019), this paper briefly highlights his biography, education, and academic career; however, it is mainly concerned with his scholarly concepts and theories. The author attempts to follow the development process of one of his main contributions to social sciences, the world-systems approach, as well as to analyze various important aspects of it, including its historic and philosophic significance. All efforts have been made to keep the paper informative yet also accessible and transparent, deferring, when appropriate, to Immanuel Wallerstein himself to expound his ideas to the …

Legal Geographies And Political Ecologies Of Water Allocation In Maui, Hawai'i, Alida Cantor, Kelly Kay, Chris Knudson

Geography Faculty Publications and Presentations

Throughout the Hawaiian Islands, sugar plantations have controlled a large proportion of water resources for over a century, often leaving little water in streams to support ecosystems or Native Hawaiian cultural and agricultural practices. Recently, in Maui, Hawai‘i, community activists and lawyers representing Native Hawaiian and environmental interests have successfully reclaimed water resources for instream flow utilizing legal processes and tools such as Hawai‘i’s public trust doctrine, which has plural roots in both Hawaiian and Western legal traditions. In this paper, we use qualitative fieldwork, including interviews, participant observation, and archival data collection, to explore two recent and ongoing legal …

Performance Of Us Concrete Highway Bridge Decks Characterized By Random Parameters Binary Logistic Regression, Omar Ghonima, Jason C. Anderson, Thomas Schumacher, Avinash Unnikrishnan

Civil and Environmental Engineering Faculty Publications and Presentations

This study employs a random parameters binary logistic regression (LR) to characterize the impact of environmental and structural parameters on concrete highway bridge deck deterioration nationwide. Two specific gaps in the literature are addressed: (1) the use of a nationwide dataset for analysis, and (2) the implementation of a methodology to account for unobserved heterogeneity. A total of 3,262 bridge deck deterioration observations derived from the authors’ nationwide concrete highway bridge deck performance inventory (NCBDPI) database were used in this study. The deterioration rate (DR) was computed as the decrease in the concrete bridge deck condition rating ( …

Population Collapse And Retreat To Fire Refugia Of The Tasmanian Endemic Conifer Athrotaxis Selaginoides Following The Transition From Aboriginal To European Fire Management, Andres Holz, Samuel W. Wood, Carly Ward, Thomas T. Veblen, David M.J.S. Bowman

Geography Faculty Publications and Presentations

Untangling the nuanced relationships between landscape, fire disturbance, human agency, and climate is key to understanding rapid population declines of fire‐sensitive plant species. Using multiple lines of evidence across temporal and spatial scales (vegetation survey, stand structure analysis, dendrochronology, and fire history reconstruction), we document landscape‐scale population collapse of the long‐lived, endemic Tasmanian conifer Athrotaxis selaginoides in remote montane catchments in southern Tasmania. We contextualized the findings of this field‐based study with a Tasmanian‐wide geospatial analysis of fire‐killed and unburned populations of the species. Population declines followed European colonization commencing in 1802 ad that disrupted Aboriginal landscape burning. Prior to …

Visualizing Statewide Trips: Tools To Leverage Gps Data In Transportation Planning, Nikola Markovic

TREC Project Briefs

The University of Utah has a new data visualization service to offer to state DOTs and other agencies. Using Small Starts funding from the National Institute for Transportation and Communities (NITC), researcher Nikola Markovic and his team have developed a suite of visual analysis tools to demonstrate how GPS trajectory data can help accurately model and analyze mobility trends. These data are typically purchased from vendors, which means that transportation agencies must first understand the benefits before they decide to invest in data acquisition.

Law And Development In The United States: A Nexus With Civil Rights, Yong-Shik Lee

Southern Illinois University Law Journal

Several decades have passed since the civil rights movement began. The movement achieved historic success owing to the efforts of so many who dedicated their lives to the call of justice and equality. This remarkable success has led to an improved society that accords the legal protection of equal rights among different races, genders, and ethnic groups. Despite this important achievement, we still have a long way to fulfilling the full promise of the civil rights movement, which at its core lies the protection and promotion of equity and dignity of all people.

An Invasion Of Privacy: Genetic Testing In An Age Of Unlimited Access, Najla Hasic

Southern Illinois University Law Journal

This Note discusses how privacy rights are implicated when direct-to-consumer (DTC) genetic testing companies disclose an individual’s genetic information to law enforcement officers—often without any warrant or legal procedures required—who then use that data to implicate an individual’s family members in crimes.

After a brief introduction, Part II of this Note discusses DNA, what it is, and how it is used and tested by both state and private actors. It also provides a brief history of the Fourth Amendment with a specific focus on its application in jurisprudence as technology advances and privacy rights diminish. Finally, an overview of current …

Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer

Geography

This viewpoint takes stock with the ‘geography of sustainability transitions’ (GOST) as it is presented in the transitions research agenda. GOST has been a relatively recent addition to transition theorizing, addressing the need for greater sensitivity and attention to the scales, spatialities, and context-specific factors that shape transitions. In our view, the agenda represents a rather narrow perspective on GOST, which is geared to two empirical themes, namely urban transitions and transitions in developing countries. While these are relevant and topical issues, the section lacks sufficient acknowledgement of the increasing engagement of geographers with transitions studies and the theoretical approaches …

Global Pattern And Change Of Cropland Soil Organic Carbon During 1901-2010: Roles Of Climate, Atmospheric Chemistry, Land Use And Management, Wei Ren, Kamaljit Banger, Bo Tao, Jia Yang, Yawen Huang, Hanqin Tian

Plant and Soil Sciences Faculty Publications

Soil organic carbon (SOC) in croplands is a key property of soil quality for ensuring food security and agricultural sustainability, and also plays a central role in the global carbon (C) budget. When managed sustainably, soils may play a critical role in mitigating climate change by sequestering C and decreasing greenhouse gas emissions into the atmosphere. However, the magnitude and spatio-temporal patterns of global cropland SOC are far from well constrained due to high land surface heterogeneity, complicated mechanisms, and multiple influencing factors. Here, we use a process-based agroecosystem model (DLEM-Ag) in combination with diverse spatially-explicit gridded environmental data to …

Direct Assessment Of Mental Health And Metabolic Syndrome Amongst Indonesian Adolescents: A Study Design For A Mixed-Methods Study Sampled From School And Community Settings, Peter S. Azzopardi, Lisa Willenberg, Nisaa Wulan, Yoga Devaera, Bernie Medise, Aida Riyanti, Ansariadi Ansariadi, Susan Sawyer, Tjhin Wiguna, Stanley Luchters

Population Health, East Africa

Non-communicable diseases (NCDs) are the leading cause of morbidity and mortality globally, with the burden largely borne by people living in low- and middle-income countries. Adolescents are central to NCD control through the potential to modify risks and alter the trajectory of these diseases across the life-course. However, an absence of epidemiological data has contributed to the relative exclusion of adolescents from policies and responses. This paper documents the design of a study to measure the burden of metabolic syndrome (a key risk for NCDs) and poor mental health (a key outcome) amongst Indonesian adolescents. Using a mixed-method design, we …

The Flint Water Crisis And Community Water Fluoridation: A Lesson In Communication. Communicating With The Public And Connecting With Community Leaders, Traci J. Dantzler Dds, Raymond Gist Dds

The Journal of the Michigan Dental Association

This article presents how not only was Flint’s water compromised lead contamination of residential waterlines during the Flint Water Crisis, but area dentists had to work hard to refute unsubstantiated claims that adding fluoride to the community water supply increased the level of lead in the water. Oral health advocacy to reassure citizens and build confidence in the community water supply following remediation efforts required sharing the best evidence while most importantly actively listening to assure that community members were heard; that they felt that they have a voice, and to know that we are here to listen to their …

Patterns In Size Distribution And Catch Of Rockfish (Sebastes Spp.) In Fisheries-Independent And Fisheries- Dependent Hook-And-Line Surveys On The Central Coast Of California, Rose Elizabeth Dodgen

Master's Theses

Stock assessments are statistical models which characterize the state of a population of fish. Data for stock assessment models of West Coast nearshore groundfish come largely from fisheries-dependent sources. Incorporating fisheries-independent data would increase data availability. A potential source of fisheries-independent data which is comparable to existing fisheries-dependent data is the California Collaborative Fisheries Research Program (CCFRP), a Marine Protected Area (MPA) monitoring study. We are interested in understanding the context in which CCFRP could be implemented into assessments of nearshore groundfish, specifically rockfish. To investigate this, we used management-relevant metrics to examine three questions concerning the implementation of CCFRP …

The Effect Of Language On Voter Opinion: Results From A Survey Experiment In Thailand, Jacob I. Ricks

Research Collection School of Social Sciences

Politicians have long engaged in marketing themselves by employing distinct speaking styles to signal social standing, competence, or a shared background with their audience. What effect does this use of different language appeals have on voter opinion? Utilizing a survey experiment in Thailand, I test a set of hypotheses about the effect of language on respondent opinions. Relying on three distinct treatments, a formal language register, an informal language register, and an ethnic language, I demonstrate the multiple effects of language on political appeal. The use of a formal register has mixed effects, signaling both high education as well as …

Bayesian Calibration At The Urban Scale: A Case Study On A Large Residential Heating Demand Application In Amsterdam, Cheng-Kai Wang, Simon Tindemans, Clayton Miller, Giorgio Agugiaro, Jantien Stoter

Research Collection College of Integrative Studies

A bottom-up building energy modelling at the urban scale based on Geographic Information System and semantic 3D city models can provide quantitative insights to tackle critical urban energy challenges. Nevertheless, incomplete information is a common obstacle to produce reliable modelling results. The residential building heating demand simulation performance gap caused by input uncertainties is discussed in this study. We present a data-driven urban scale energy modelling framework from open-source data harmonization, sensitivity analysis, heating demand simulation at the postcode level to Bayesian calibration with six years of training data and two years of validation data. Comparing the baseline and the …

Not A Megachurch? Creative Methods Toward Intergenerational Worship Within A Small Evangelical Church: A Case Study, Brenda L. Widger

Doctoral Dissertations and Projects

Larger churches have historically had the advantage in the realm of creative worship ministry due to larger budgets, more volunteers and dedicated professional staff. While megachurches have dominated the creative worship model, smaller evangelical churches have struggled to capture the essence of creativity in their services. There is a need to explore the obstacles faced by the smaller church along with methods that can be applied to overcome the challenges to offer effective worship experiences that include creative worship elements in a multigenerational model. In this qualitative historical case study, insight into the processes and resources necessary to move the …

The Impact Of Temporary Gender Embodiment On The Accuracy Of Personality Judgment: Drag Performance As A Lens, Adele Weaver

Undergraduate Theses and Capstone Projects

Accurately perceiving the personalities of others may allow a person to be more successful in social and professional settings. Past research has supported that drag performers who are extroverted tend to be more successful in their job (Hopkins, 2004). It also has been supported that extroverted people, who are also referred to by Vogt and Colvin as “interpersonally-oriented,” are better at accurately judging others’ personalities (2003).The influence of gender on perceiving abilities is addressed in this study; it observes whether or not drag performers more accurately perceive the personalities of others because of their interpersonal orientation. It has been found …

Mult-Spectral Imaging Of Vegetation With A Diffractive Plenoptic Camera, Tristan R. Naranjo

Theses and Dissertations

Snapshot multi-spectral sensors allow for object detection based on its spectrum for remote sensing applications in air or space. By making these types of sensors more compact and lightweight, it allows drones to dwell longer on targets or the reduction of transport costs for satellites. To address this need, I designed and built a diffractive plenoptic camera (DPC) which utilized a Fresnel zone plate and a light field camera in order to detect vegetation via a normalized difference vegetation index (NDVI). This thesis derives design equations by relating DPC system parameters to its expected performance and evaluates its multi-spectral performance. …

Spacecraft Position Estimation And Attitude Determination Using Terrestrial Illumination Matching, Liberty M. Shockley

Theses and Dissertations

An algorithm to conduct spacecraft position estimation and attitude determination via terrestrial illumination matching (TIM) is presented consisting of a novel method that uses terrestrial lights as a surrogate for star fields. Although star sensors represent a highly accurate means of attitude determination with considerable spaceflight heritage, with Global Positioning System (GPS) providing position, TIM provides a potentially viable alternative in the event of star sensor or GPS malfunction or performance degradation. The research defines a catalog of terrestrial light constellations, which are then implemented within the TIM algorithm for position acquisition of a generic spacecraft bus. With the algorithm …
