Method: A pre-post quasi-experimental study was …

Shifting Faith Among Indigenous People In Arunachal Pradesh, India: Revisiting Greenfeld's Civilizational Framework, M. Amin Khan

Comparative Civilizations Review

This paper examines changing religious demography in Arunachal Pradesh through Liah Greenfeld's theory of civilization as a self-generating and self-reproducing symbolic reality. Using decadal Census data (1971–2011), it traces the demographic decline of Indigenous/Tribal religions classified under “Other Religions and Persuasions” (ORP) alongside the widespread growth of Christianity and the more limited growth of Hinduism. The analysis argues that these demographic shifts reflect more than religious conversion; they reveal differential capacities for cultural reproduction. Whereas civilizations endowed with codified first principles and enduring institutions sustain continuity across generations, Arunachal Pradesh's largely localized and orally transmitted indigenous traditions have proven less …

A Study Of Phylogenetic Relationships Of Dichanthelium Based On Plastomes, Humera Fatima

Theses

Dichanthelium (Hitchcock & Chase) Gould is a genus in the grass family (Poaceae) with a wide range of morphological diversity, exhibiting significant ecological differences. Despite this, its evolutionary relationships are not fully understood. The ambiguity surrounding the boundaries of lineages and the relationships among species has hindered the systematics of the genus. This study aimed to reconstruct the phylogenetic relationships within Dichanthelium, verify the monophyly of species, and evaluate the strength of the inferred relationships across different analytical frameworks. Molecular sequence data of entire plastomes were examined using both maximum likelihood and Bayesian inference methods to develop phylogenetic hypotheses. Phylogenies …

A Stabilized Weighted Interior Penalty Method For Thermal Convection Model In Heterogeneous Porous Media, Yuanyuan Hou, Qianqian Ding, Xiaoming He, Yanping Lin

Mathematics and Statistics Faculty Research & Creative Works

In this article, we propose and analyze a stabilized weighted interior penalty method for solving the thermal convection problems in heterogeneous porous media. We first transform the thermal convection model into the pressure primal form with homogeneous Neumann boundary condition and develop a symmetric weighted interior penalty method to handle the discontinuous Darcy number and automatically adjust the penalty coefficient corresponding to the varying permeability. Then we recover the velocity by a stabilized method and incorporate it into the energy equation to obtain the temperature. The stability and convergence rates of the numerical solutions are rigorously proved and verified by …

Development And Validation Of A Multidimensional Measure Of Role Ambiguity: Integrating Nlp-Based Factor Analytic Techniques With Traditional Psychometrics, Md Allama Ikbal Sijan

Theses, Dissertations and Culminating Projects

This dissertation developed and validated the Multidimensional Role Ambiguity Scale (MRAS), a measure that separates role ambiguity into five subdimensions: goal/expectation/responsibility ambiguity, process ambiguity, priority ambiguity, behavior ambiguity, and performance criterion ambiguity. Although role ambiguity is one of the most studied role stressors in organizational research, it has been measured largely as a single global score, a practice that masks differences among its facets and may explain the inconsistent criterion relationships reported in prior work. Scale development followed the three-step framework of Singh and Rhoads (1991). Thirty items were generated from working definitions grounded in role theory, and fifteen research …

Temperature And Salinity Effects On The Physiology Of Bullfrog Tadpoles (Lithobates Catesbeianus) From A Suburban Temperate Wetland, Angela Brown

Theses, Dissertations and Culminating Projects

One of the most robust amphibians is the American Bullfrog, Lithobates catesbeianus, which is a widespread species that is invasive worldwide, and is broadly tolerant of a range of environmental conditions. Despite this tolerance, survival and performance of adult L. catesbeianus can be negatively affected by increasing temperatures and salinity resulting from anthropogenic impacts, such as climate change and road salts. This study focuses on the effects of acute salinity exposure (mimicking road salt influx into a pond) on L. catesbeianus tadpoles at different larval stages. Increased salinity was predicted to negatively affect two physiological performance measures. Critical maximum temperature …

Theses & ETDs

A growing area of climate research explores the forms of government best equipped to confront the climate crisis and shape long-term environmental policy. The theories amongst this research seem to advocate for polar solutions: authoritarianism or democracy. Climate change and related ecological challenges increasingly test the capacity of existing political systems to deliver timely and effective responses. This research project aims to answer the questions: To what extent does democracy influence the adoption and implementation of national climate policy? How do democracies and autocracies differ in the strength and durability of their climate policies? Investigating this relationship can inform future …

The Startup: Critical Perspectives On Technology Entrepreneurship And Digital Labor, Kochav Koren

All Duquesne Faculty Scholarship

Communication and media studies are rapidly reshaped by socio-technological forces within the framework of informational capitalism, where startups emerge as key drivers of the global creative economy. This study critically examines the global startup movement through political economy, classical sociology, and Southern perspectives to assess whether digital entrepreneurship fosters genuine, decentralized innovation or perpetuates speculative financialization and labor precarity. Employing a multi-layered theoretical framework—including Schumpeterian creative destruction, Marxist commodity fetishism, and Weberian charismatic authority—and qualitative fieldwork across North and Latin American tech hubs, the analysis reveals startups as network enterprises that both disrupt markets and reproduce structural inequalities. The findings …

The Misinterpretation Of “Corporation” In Indonesia’S Penal Code No. 1 Of 2023: Ensuring Legal Certainty For Recognized Corporate Forms, Rizaldy Alif Syahrial

Indonesia Law Review

Abstract

Law No. 1 of 2023 on the Indonesian Penal Code expands criminal liability to include entities that do not possess legal personality, allowing informal entities such as commanditaire vennootschappen (CV), partnerships (firm), unincorporated business groups, and unregistered associations to be prosecuted as corporations. This expansion aims to close legal loopholes in addressing modern criminal activity and to align Indonesia with global developments in corporate criminal liability. However, extending criminal liability to non legal persons generates conceptual tension because Indonesian legal doctrine distinguishes between natural persons and legal persons, which possess legal personality, decision making organs, separate assets, and autonomous …

Cash, Cleats, And Carpools: A Multi-Method Investigation Of Resource Allocation In Families With Youth Athletes, Emily Susan Delisle

All Graduate Theses and Dissertations, Fall 2023 to Present

The current thesis is an investigation of time and financial resource allocation in families with youth athletes. Study 1 used a survey questionnaire to explore how the number of athletes in a family impacted the way parents allocated time and financial resources to their oldest child’s youth sport participation. Results indicate that an increase in the number of athletes in a family does not decrease parents’ time or financial commitments to their oldest child’s youth sport participation. Study 2 used interviews to explore how nine parents with multiple athletes experienced the intersecting demands of time, finances, and family life while …

Bees In The Trap: Leveraging Bumble Bee (Hymenoptera: Apidae: Bombus) Bycatch For Ecological And Genetic Insights, Tori L. Strausser

All Graduate Theses and Dissertations, Fall 2023 to Present

Managers rely on insect monitoring traps to detect insect pests that harm crops and protect food and other agricultural production. However, these traps also capture non-target insects, including bumble bees, raising concerns about whether repeated trapping could harm pollinator populations. This thesis explores whether bees caught as non-targets, also called bycatch, in routine pest monitoring traps can be used to better understand bumble bee populations, and whether traps pose risks to their long-term persistence. Using bumble bees collected from pest surveillance traps placed in crop fields across Utah, this research examined seasonal patterns in body size, timing of capture, and …

Advancing Management Strategies For Two Promising Mason Bee Species (Osmia Ribifloris And Osmia Bruneri) For Berry Pollination, Miranda L. Jones

All Graduate Theses and Dissertations, Fall 2023 to Present

Bee management can broadly refer to human manipulation of one or multiple parts of a bee’s lifecycle. Managing honey bees, commonly referred to as beekeeping, is responsible for providing most pollination for global food crops. However, using more than one bee species for crop pollination can have many benefits. Benefits include better crop pollination and insurance in case one bee species underperforms or its population collapses. Some bees within the genus Osmia are already widely managed for crop pollination because their developmental lifecycle allows bee managers to readily deploy pollinating bees in sync with varying crop blooms, and for certain …

"In Any Other Circumstance I Am Not In Work Mode. I Am Clocked Out": Chappell Roan And The Objectified Persona, Aubry Louise

All Graduate Theses and Dissertations, Fall 2023 to Present

Integrated Soil-Water Processes And Irrigation Management For Agricultural Water Optimization In Semi-Arid Regions, Tejinder Singh

All Graduate Theses and Dissertations, Fall 2023 to Present

Water is one of the most important resources for agriculture in the western United States. In semi-arid regions, farmers depend on irrigation to grow crops, but water supplies are becoming less reliable because of drought, declining snowpack, groundwater depletion, and increasing competition for limited water. Improving agricultural water use is therefore not simply about applying less water. It also requires understanding where water goes after it enters a field, how long it remains available to crops, and how farmers can use that information to make better irrigation decisions. This dissertation follows water through irrigated agricultural systems to better understand how …

Understanding And Predicting Precipitation Characteristics In The United States Through Machine Learning, Numerical Modeling And Measurements, Cody Luther Ratterman

All Graduate Theses and Dissertations, Fall 2023 to Present

Precipitation is one of the most important yet uncertain variables in the climate system. It varies dramatically in terms of timing, accumulation, rate, and phase, depending on location, season, circulation patterns, and atmospheric conditions. Precipitation forecasts, especially snowfall, are essential to supporting drought mitigation and water management in the Intermountain West. Because rainfall and snowfall lead to opposite effects on snowpack, accurately partitioning rain and snow is important to estimate snowpack levels, winter recreation, mountain ecosystems and runoff. The research findings in this dissertation have advanced the understanding and prediction of precipitation and snowpack in the U.S. by addressing the …

Experimental And Numerical Investigation Of Flow Coefficients In Three-Way, T-Port, Ball Valve, Tyler A. Mindrum

All Graduate Theses and Dissertations, Fall 2023 to Present

Many systems that move fluids, like water distribution networks and heating, ventilation, and air conditioning (HVAC) systems, rely on valves to control flow. This study evaluates a three-way valve, which can direct flow in multiple directions, but has not been extensively researched. Testing included physical data collection and computer simulations to compare how the valves behaved under different valve openings and flow conditions. The results showed that computer simulations can predict the general flow behavior of three-way valves, but that physical testing is still important, especially for valves with complex internal geometries.

Llm-As-A-Judge For Software Engineering: Literature Review, Vision, And The Road Ahead, Junda He, Jieke Shi, Terry Yue Zhuo, Christoph Treude, Jiamou Sun, Zhenchang Xing, Xiaoning Du, David Lo

Research Collection School Of Computing and Information Systems

The rapid integration of Large Language Models (LLMs) into software engineering (SE) has revolutionized tasks from code generation to program repair, producing a massive volume of software artifacts. This surge in automated creation has exposed a critical bottleneck: the lack of scalable and reliable methods to evaluate the quality of these outputs. Human evaluation, while effective, is very costly and time-consuming. Traditional automated metrics like BLEU rely on high-quality references and struggle to capture nuanced aspects of software quality, such as readability and usefulness. In response, the LLM-as-a-Judge paradigm, which employs LLMs for automated evaluation, has emerged. This approach leverages …

The Relationship Between Maintenance And Overhaul Employee Spending, Business Model, Geographic Region, And The Financial Performance Of Commercial Airlines, Naumaan Khalid Sheikh

Walden Dissertations and Doctoral Studies

After nearly 5 decades of deregulation, commercial airline leaders still lack the capability to improve financial performance by structuring their maintenance operations to gain competitive advantages in highly competitive global markets. Without an effective strategy, airline maintenance affects service and financial performance. Framed with Porter’s competitive advantage theory, this quantitative nonexperimental correlational project was to examine the relationships between airline in-house maintenance and overhaul employee spending, business model, geographic region, and financial performance of global commercial full-service carrier (FSC) and low-cost carrier (LCC) airlines. Longitudinal panel data were collected from 121 LCCs and FSCs operating from 2001 to 2019 in …
