Social Complex Systems In Virtual Thirdspaces Of Global Education: Sites Of Structural Inequalities And Radical Pedagogical Possibilities, José Luis Jimenez-Figarotti

Electronic Theses and Dissertations 2020 - Present

While Collaborative Online International Learning (COIL) and Virtual Exchange (VE) are celebrated as democratizing tools fostering intercultural understanding, this techno-utopian narrative obscures a complex reality: the virtual classroom is a contested social field where global inequalities are reproduced and amplified. This dissertation interrogates this paradox, exploring how structural inequalities, digital divides, and epistemic hierarchies are negotiated within the Virtual Thirdspace of global education. Integrating Structural Inequalities (Galtung, 1969; Farmer, 2004; Tilly, 1998; and Young, 2008), Critical Environmental Justice (Pellow, 2018), Intersectionality (Crenshaw, 1989), World-Systems Analysis (Wallerstein, 1974), and Thirdspace theory (Soja, 1996), the study examines this terrain as both a …

Nonparametric Control Charts Estimation Using Hybrid Cyber-Intelligence Algorithms For Stock Market Monitoring, Mariam Jumaah Mousa, Munaf Yousif Hmood

Journal of Economics and Administrative Sciences

This paper introduces a novel nonparametric hybrid cyber-intelligence-based statistical process control and anomaly detection framework in time series data. It is developed to overcome the shortcomings of the classical control schemes in dealing with complex, abnormal, and noisy input data, especially when it is autocorrelated. The proposed methodology combines three technical pillars: First, it utilizes a bidirectional long-short-term memory architecture (Bi-LSTM) to capture long-term time dependency and learn nonlinear patterns, leaving only true deviations as residuals that remove trends and noises from the market. Second, it adopts the Golden Eagle Optimizer (GEO) algorithm for optimal parameter selection. This intelligent algorithm …

Impact Of The Sustainability Indicators On Agricultural Output In Iraq For The Period (1990–2024), Noor S. Mohammed, Basim H. Al-Badri

Journal of Economics and Administrative Sciences

This study uses an econometric approach to examine how sustainability indicators affect agricultural output in Iraq. Water sustainability, food security sustainability, the agricultural labor force, and virtual water imports are independent variables, and agricultural output is the dependent variable. The analysis uses annual data from 1990 to 2024. The Autoregressive Distributed Lag (ARDL) model is applied to analyze both short- and long-run relationships. Specifically, the results confirm the existence of a long-run equilibrium relationship between sustainability indicators and agricultural output. In the long run, water sustainability positively affects agricultural output, indicating a direct, expected relationship. Furthermore, food security sustainability has …

The Role Of Zinc Precursor Concentration In Modulating The Structural, Optical, And Electrical Properties Of Sol-Gel Derived Czts Thin Films, Justine John Tibaijuka

Tanzania Journal of Science

The films were annealed rapidly at 540 °C by using an RTP furnace. Results show the significant influence of zinc concentration on films’ properties with band gap evolution between 1.46 and 1.7 eV, along with high absorption coefficients exceeding 10⁴ cm⁻¹ in the visible range. Structurally, the films evolved from poorly crystalline at low Zn content to well- crystallized, (112)-oriented kesterite near stoichiometry. However, excessive Zn caused slight degradation …

Linear Programming Model For Optimal Crop Allocation Under Varying Land Sizes In Pawaga, Tanzania, Mustapha Abbas Kiswanya, Seleman Ismail, Saul Mpeshe

Tanzania Journal of Science

Farmers often rely on intuition when selecting crops, which can lead to suboptimal profits. In this study, we examine the optimal annual crop allocation under varying land sizes for farmers in Pawaga, Iringa District, Tanzania. A parametric linear programming (LP) model is developed to determine crop allocation combinations that maximise profit subject to land, labour, and capital constraints. Unlike conventional approaches that require separate models for different farm sizes, the proposed model accommodates land holdings ranging from 1 to 9 acres and integrates nine crop types within a single framework. Data were collected over three (3) agricultural seasons from extension …

From Tragedy To Liberation: The Tragic Mulatta And Abolition Democracy At The Intersection Of Race And Gender In The Quadroons And The Octoroon, Maram Mohammed Mahmoud Samman

University of Tabuk Journal for Humanities and Social Sciences

This essay explores the figure of the tragic mulatta in Lydia Maria Child’s The Quadroons and Dion Boucicault’s The Octoroon, analyzing how mixed-race female characters critique the racial and gender hierarchies of 19th-century America. Using an intersectional lens, it examines how race, gender, and class shape the identities and tragic fates of Xarifa and Zoe—women who were socially excluded from both Black and White communities. Drawing on W.E.B. Du Bois’s concept of double consciousness and the framework of Abolition Democracy, the essay argues that the tragic mulatta is not merely a narrative trope but a site of political tension and …

Modelling Of Dust Devil Flow Dynamics: Effects Of The Sharpness Parameter On Velocity And Pressure, Deepanshu Kumar, Hossein Jafari

Mathematical Modelling and Numerical Simulation with Applications

This work discusses the development of a straightforward model of dust devils, demonstrating a method for estimating wind speed and pressure. The current model incorporates momentum equations and the mass conservation equation for steady, axisymmetric, inviscid, and incompressible flow. In this model, the radial velocity is first considered, which is restricted in both the radial and axial directions. The sharpness parameter is also incorporated into the radial velocity formulation, as described by Vatistas model. Using the radial velocity as a foundation, we derive the azimuthal and axial velocities. The study further evaluates the pressure. Notably, for large values of the …

Dynamical Behavior, Extinction And Persistence In A Stochastic Delayed Two-Strain Epidemic Model With A Generalized Crowley-Martin Incidence Rate, Amina Allali, Dounia Bentaleb, Saida Amine

Mathematical Modelling and Numerical Simulation with Applications

This paper develops and analyzes a novel delayed stochastic SIR epidemic model with two interacting strains and general incidence functions. By establishing the existence and uniqueness of a positive global solution, the well-posedness of the model under stochastic perturbations is ensured. Extinction occurs when the stochastic reproduction number falls below unity, as demonstrated through Itô calculus and martingale convergence theorems, while persistence is guaranteed under the Crowley–Martin incidence when it exceeds one. Numerical experiments based on the Positive Preserving Truncated Euler–Maruyama (PPTEM) scheme confirm the analytical predictions and highlight the influence of time delay and noise intensity on the long-term …

Numerical Method For Strongly Variable-Density Flows At Low Mach Number: Flame-Sheet Regularisation And A Mass-Flux Immersed Boundary Method, Matheus P. Severino, Fernando F. Fachini, Elmer M. Gennaro, Daniel Rodríguez, Leandro F. Souza

Mathematical Modelling and Numerical Simulation with Applications

A low-Mach-number flow, in the laminar regime, has intrinsically two characteristic spatial scales for a given time scale, or two characteristic temporal scales for a given spatial scale, and these dual scales are very different due to the disparity between the flow and acoustic speed. Therefore, low-Mach-number flows impose mathematical and computational challenges in their description. Standard numerical methods for compressible flows, which are typically designed for problems with a single dominant spatial and temporal scale, require alternative approaches, such as preconditioning techniques or solvers tailored for low-Mach-number equations. The present work introduces a simplified fluid dynamics model for flows …

A Case Study Of Sport And Racism In Australia: A Qualitative Document Analysis, Vegneskumar Maniam, Kristy O’Neill

Asia-Pacific Social Science Review

Australia is well known as a ‘sporting nation’ with outstanding elite sporting achievements and grassroots-level sports participation. The reality for Australia’s First Nations people and those from Culturally and Linguistically Diverse (CALD) backgrounds, however, tends to differ from the mainstream Australian population. One of the contributing factors being argued within this paper is the prevalence of historical and contemporary racism in Australian sport. This study focuses on four of Australia’s most popular community-participation sports, including Australian Rules Football (ARF), Cricket, Netball, and Swimming. Using a Qualitative Document Analysis method, this research investigates both primary and secondary sources for instances of …

Conditionals And Modalities In Constructive Quantum Logics, Juan P. Aguilera, Guillaume Massas

Mathematics, Physics, and Computer Science Faculty Articles and Research

We investigate logics that generalize both intuitionistic logic and quantum logic. In earlier work, we introduced Ex-logic, an extension of Holliday's fundamental logic that coincides with the intersection of orthologic and the implication-free fragment of intuitionistic logic. In this paper, we add an implication connective to Ex-logic and axiomatize iEx-logic, the intersection of full intuitionistic logic and orthomodular logic with the implication connective interpreted as the Sasaki hook. As a consequence, we obtain a characterization of the lattice of logics extending iEx-logic as the product of the lattice of intermediate logics and the lattice of orthomodular logics. We also explore …

Generative Endurance Logic: An Axiomatic Framework For Reasoning About Outcome-Generating Objects Under Constraints, Hafiz Burhan Ul Haq, Muhammad Nauman Irshad

Neutrosophic Systems with Applications

This paper introduces Generative Endurance Logic (GEL), a formal framework for studying objects through the outcomes they can produce. In many cases, an object cannot be judged only by a fixed truth value, score, or utility value. A rule, model, action, or strategy may behave well in one situation but fail when the context changes or when small perturbations occur. GEL addresses this issue by treating each object as a generator of outcomes. Each object a is linked to a generation map Ga:X×Ω→Y, where X is the context space, Ω is the …

Interval-Valued Neutrosophic Dombi Bonferroni Mean Aggregation Operators In Medical Diagnosis And Sustainable Energy, Maryam Faisal, Muhammad Nadeem, Muhammad Kamran

Neutrosophic Systems with Applications

Medical diagnosis is one of the most difficult fields in which decisions must be made due to the fact that medical information often has characteristics of uncertainty, incompleteness, imprecision and even contradiction. Traditional aggregation and decision-making methods are often not well suited to such complexities, and may result in less reliable diagnostic outcomes. In order to overcome these drawbacks, the authors propose a new approach using a novel representation of Interval-Valued Neutrosophic Sets (IVNSs), the Dombi operational laws, and Bonferroni Mean (BM) aggregation operators. The proposed framework is specifically aimed at coping with uncertainty, indeterminacy and falsity all at once …

An Interactive Multi-Objective Programming Approach For Optimizing Fully Trapezoidal Spherical Fuzzy Linear Programming Problem With Application, Sultan S. Alodhaibi, Hissah Ibrahim Almuzini, Hamiden Abd El-Wahed Khalifa

Neutrosophic Systems with Applications

In this paper, a linear programming framework with completely uncertain parameters is investigated by employing trapezoidal spherical fuzzy numbers (TrSFNs). The proposed formulation incorporates a spherical fuzzy (SF) decision environment in which the optimization process simultaneously maximizes the degree of positive membership while minimizing the corresponding neutral and negative membership degrees. By utilizing the concept of the α -cut associated with TrSFNs, the original fully fuzzy linear programming problem is transformed into an interval-valued linear programming model with confidence levels. To rank and compare the resulting interval objective values, an interval ordering approach based on the decision maker's preferences—considering the …

Exploring Tourism Business Voices In Navigating Pandemic Crisis And Resilience-Building, Godwin Adiel A. Lema

Tanzanian Economic Review

COVID-19 challenged mobility, redefining crisis navigation and resilience. A modified Challenge Metamorphosis Model (CMM) is proposed to understand crisis navigating process in tourism business resilience-building. A pragmatic mixed-method design, involving 158 tourism-business respondents, multiple regions, interviews, and observation during June–November 2020, was applied. Impacts, challenges, opportunities, varied business responses and outcomes were mirrored. Immediate reactive closure and booking cancellation responses were distinguished from proactive adaptive business continuity measures with low visitors, postponement, few bookings and negotiable employment flexibility. Health, safety, and culturally embedded coping practices and their reinvention aided crisis navigation. Medium-term crisis navigating strategies were differentiated from long-term resilience-building …

Hydroclimatic Whiplash Across The Contiguous United States: Characterizing Wet–Dry Transitions In Pdsi And Phdi, James Lam, Thomas Christopher Piechota

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Hydroclimatic whiplash, characterized by rapid transitions between wet and dry conditions, poses a growing challenge for water resource management and ecosystem stability. However, the spatial and statistical characteristics of wet–dry transitions across the contiguous United States are not fully understood. This study analyzed Palmer Drought Severity Index (PDSI) and Palmer Hydrological Drought Index (PHDI) records from 344 NOAA climate divisions spanning 1895–2024. Whiplash was defined as a transition between severe drought and severe wetness within 12-month rolling windows. Statistical descriptors including lag-1 autocorrelation, variance, and skewness were evaluated for whiplash and non-whiplash windows to assess differences between them. Whiplash hotspots …
