Journal of Economics and Administrative Sciences

The objective of this paper is to investigate the effect of the earnings ratio and capital structure on share price, with special focus on the moderating role of free cash flow (FCF) in the manufacturing sector listed on the Iraqi Stock Exchange (ISX) for the period 2016 to 2023. Using a quantitative research method, the study draws data from audited financial statements, including the income statement, balance sheet, and cash flow statement, and analyzes 10 manufacturing companies over eight years. The analysis employs a regression model, descriptive statistics, correlation analysis, ANOVA, and tests of cross-sectional dependence and non-stationarity to ensure …

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 …

Exploiting Uncertainty Of Computational Methodology In Optimizing User Interface In Human-Computer Interaction, Nada Mohamed, Alshaimaa A. Tantawy

Neutrosophic Systems with Applications

Human-computer interaction (HCI) evaluation and optimization of user interfaces (UIs) constitute a complex multi-criteria decision-making challenge, marked by conflicting evaluation dimensions, subjective expert judgments, and inherent uncertainty in user experience assessment. Traditional evaluation approaches, such as heuristic expert reviews and user satisfaction surveys, rely on sharp, binary classifications that fail to capture the gradual and overlapping nature of human cognitive and affective states. This limitation necessitates a more robust uncertainty-aware methodology that can model the true complexity of HCI evaluation. This paper proposes a hybrid mathematical model that integrates various Multi-Criteria Decision Making (MCDM) techniques of Entropy, and Simple Additive …

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 …

Skill Acquisition: Evaluation Of Instructional Procedures, Ellen I. Ratliff

USF Tampa Graduate Theses and Dissertations

Identifying effective and efficient interventions is essential for establishing independent responding in learners with autism spectrum disorder and related developmental disabilities. The present study replicated and extended Gorgan and Kodak (2019) by comparing differential reinforcement, most-to-least prompt fading, and extended response interval procedures for teaching novel skills to three children with autism spectrum disorder who did not demonstrate prompt-dependent responding. Using an adapted alternating treatments design, each intervention was evaluated against a control condition with an equated opportunity interval. Extensions to prior research included conducting a reinforcer assessment to verify differentiation in stimulus potency, modifying the controlling prompt assessment to …

Serial Radiographic And Ultrasonographic Evaluation Of Discospondylitis In A Cat: A Case Report Of Progressive Vertebral Lysis Despite Clinical Improvement, Geunah Kim, Jungho Lee, Seulgi Bae, Sang-Kwon Lee, Kija Lee

The Thai Journal of Veterinary Medicine

A 10-year-old castrated male Korean Shorthair cat was presented with a 5-day history of lethargy and nonambulatory paraparesis. Neurological examination revealed delayed postural reactions in both pelvic limbs. Initial radiography of the lumbar spine revealed narrowing of the L7–S1 intervertebral disc space with ventral bony proliferation. Magnetic resonance imaging revealed collapse of the L7–S1 intervertebral disc space with heterogeneous T2-weighted hyperintensity and ventral contrast enhancement of the affected disc, as well as contrast enhancement of the adjacent paraspinal musculature. These findings suggested the presence of discospondylitis. Coccoid bacteria detected in both urine and splenic fine-needle aspirate indicated hematogenous spread. The …

Microelement Deficiencies In Perimenopausal Women And Their Impact On Metabolic And Physical Performance: Potential Applications Of Vis–Nir Tissue Spectrophotometry And The So/Check Platform, Izabela Pabin, Damian M. Dudek, Łukasz Jaworski, Ewa Maria Kłodzińska

Baltic Journal of Health and Physical Activity

Background: The perimenopausal period, typically occurring between the ages of 40 and 55 years, represents a critical transitional stage in women’s physiology characterized by profound hormonal, metabolic, and systemic adaptations. While the endocrine aspects of this transition have been extensively investigated, increasing attention has recently been directed toward the role of micronutrient homeostasis in maintaining metabolic health and physical performance during this period. Therefore, the aim of this narrative review is to summarize current knowledge regarding microelement deficiencies in perimenopausal women and their potential impact on metabolic health and physical performance. Additionally, the review discusses the potential applications of VIS–NIR …
