Methodological Quality of Grounded Theory in Mathematics Education Researches: A Systematic Review

This study aimed to provide a systematic review by evaluating the accuracy and quality of mathematics education research that employed the grounded theory methodology. A systematic search was conducted in the databases (EBSCO), (SAGE Journals), (Google Scholar), (Springer), and (Eric) to identify studies in the field of mathematics education that mentioned the use of grounded theory methodology and/or methods in the title, abstract, or methodology. The descriptive characteristics and methodological quality of eligible studies were examined using evaluation guidelines developed by (Hutchison et al., 2011). The review included eighteen research papers conducted between 2010 and 2023. The results showed that the grounded theory methodology is increasingly being used by researchers. Five studies (33%) provided a good understanding and appropriate application of grounded theory methodology through their adherence to the six principles. The rates of application of the principles of grounded theory were variable, although most studies did not adhere to the principles of grounded theory and its capabilities were not exploited well, such as memos, theoretical sampling, use of charts and tables, theoretical saturation, and integration of theory with the literature, which was reflected in the opportunities for theoretical innovation. Keywords: grounded theory, methodological quality of grounded theory, mathematics education research

MONITORING SAND MIGRATION IN AL AIN CITY UTILIZING REMOTE SENSING TECHNIQUES

Sand migration significantly impacts urban development, infrastructure, and ecosystems in arid regions such as Al Ain city, United Arab Emirates (UAE). This study employs advanced remote sensing techniques to monitor and predict sand dune migration across the Sieh Al Hama dune field, a critical area west of Al Ain. The research objectives include quantifying dune migration rates over three years (2018–2020) using monthly Sentinel-2 satellite imagery, identifying distinct dune fields, and analyzing the textural and mineralogical properties of dune sediments to infer their provenance. Field sampling from four dunes (Large Sabra Dune, Dune 1, Dune 2, and Dune 3) was coupled with laboratory analyses, including grain size distribution, X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The COSI-Corr software facilitated precise measurement of dune displacement, revealing well-sorted fine to medium sand dominated by quartz (up to 89.67%) and carbonates (up to 14.25%), with minor heavy minerals indicating mixed local (Oman Mountains, Jabal Hafit) and distant sources. The results demonstrate significant interannual variability, with the rate of migration peaking in 2019 (average 3.32 m) and changing seasonally, influenced by wind patterns. These findings indicate the effectiveness of remote sensing in tracking sand dynamics, providing important insights for urban development and environmental management in desert areas

QUADRATIC STOCHASTIC PROCESSES: ALGEBRAIC STRUCTURES AND THEIR APPLICATIONS

This research focuses on the algebraic structures of the Quadratic Stochastic Processes (QSPs). In this work, we first study ()- Quadratic Stochastic Operators (QSOs) linked to the partition ℙ3. We simultaneously discuss the dynamics of the obtained QSOs. Moreover, the algebraic structure of the associated genetic algebra is studied. Further, we build Quadratic Stochastic Processes (QSPs) using the given Markov processes. Consequently, we obtain an ordinary differential equation for the resultant Quadratic Stochastic Processes (QSPs). Besides, we apply the solution of this ordinary differential equation to the option pricing problem. Thereafter, we construct Quadratic Stochastic Processes (QSPs) in three-dimensional space by utilizing the parameters of the Susceptible-Infected-Recovered (SIR) model. In addition, we investigate the algebraic properties of the limiting genetic algebras. Rota-Baxter operators are also analyzed for different weights for these algebras. In the application part of this analysis, we propose an option pricing under the Quadratic Stochastic Process (QSP) modulated Geometric Brownian Motion (GBM) model. We also analyse the Radon-Nikodym derivative of the Equivalent Martingale Measure (EMM) with respect to the historic probability . Ultimately, we obtain an infinitesimal generator which facilitates numerical simulations of the non-Markovian and stock price processes

القياس الأدون: حقيقته وحجّيّته وتطبيقاته المعاصرة

Abstract Al-Qiyas Ad-Adwan or the Lowest Analogy : its Reality, Authority, and Contemporary Applications in Islamic Fiqh One of the types of analogy, whose interpretation and representation has been problematic in Usul al-Fiqh is the lowest analogy (al-Qiyas al-Adwan). The aim of this research is to clarify what is meant by this analogy, its reality, examples, whether it is accepted as evidence or not, and to present its applications in contemporary jurisprudential issues. To reach to this conclusion, the researcher followed the comparative analytical methodology, after tracing the roots of this kind of analogy in the main source books of Usul al-Fiqh, and extrapolating its examples in the subordinate books of Islamic Fiqh. The research concluded that the correct meaning of this analogy is that it’s the analogy whose reason (Illah) in its origin (Asl) is less in magnitude than in its branch (Far\u27a), and it is not, as per the opinion of most of the late coming scholars, who opined that it is the analogy whose ruling is not proven in its branch as strong as in its origin. The researcher also concluded that this analogy, in the said meaning, should be accepted as evidence, and it does not contradict with the requirement established by the Usul scholars for the valid analogy, in terms of the reason of its origin must be found in the branch entirely, and that it has ample applications in the books of jurists and in contemporary jurisprudence issues. ملخص البحث من الأنواع التي أشكل تفسيرها والتمثيل لها عند الأصوليين القياس الأدون أو الأدنى. وقد هدف هذا البحث إلى تجلية المقصود بهذا القياس وبيان حقيقته وأمثلته، وهل يُحتجّ به أو لا؟ ثمّ بيان تطبيقاته في المسائل الفقهية المعاصرة. وقد انتهج الباحث في الوصول إلى هذه النتيجة المنهج التحليلي المقارن، بعد تتبّع جذور القول بهذا القياس في كتب الأصول، واستقراء أمثلة له في كتب الفروع. وخلص البحث إلى أنّ المعنى الصواب لهذا القياس هو ما كانت العلة في فرعه أقلّ مقدارًا منها في أصله، وليس هو، كما قيل عند أكثر المتأخّرين، بأنّه ما كان ثبوت الحكم في فرعه دون ثبوته في أصله. وخلص أيضًا إلى أنّ هذا القياس، بالمعنى المذكور، حجّةٌ يسوغ الأخذ بها، وذلك لا يتنافى مع اشتراط الأصوليين في القياس الصحيح أن تُوجد علة أصله في فرعه بكمالها، وأنّ له تطبيقاتٍ وافرةً في كتب الفقهاء وفي المسائل الفقهية المعاصرة

ASSESSMENT OF HEAVY METAL CONCENTRATION IN BLUE SWIMMING CRABS FROM DUBAI AND SHARJAH FISH MARKETS IN UAE

Growing urbanization and industrialization along the UAE\u27s coastline exposes human health and marine life at risk of increasing heavy metal pollution in marine ecosystems. This study evaluated the levels of 19 essential and non-essential elements in blue swimming crabs (Portunus pelagicus) collected from fish markets in Dubai and Sharjah. Among these, potentially harmful heavy metals included arsenic (As), copper (Cu), cadmium (Cd), nickel (Ni), lead (Pb) and mercury (Hg). The main goals of the study were (i) to evaluate whether the concentrations of these metals exceeded maximum permissible limits and (ii) to investigate if there were male and female specific variations in metal accumulation. Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) was used to measure the concentrations of elements in crab tissues. Mean concentrations of As and Cu in male and female crabs were higher than the international food safety standards. Furthermore, the concentrations of Cd and Ni in female crabs were much higher maximum permissible limits. However, levels of mercury (Hg) in both sexes were detected to be below maximum permissible limits. Overall, while some metal concentrations exceeded safety thresholds, the total heavy metal burden across all samples was not considered toxic based on global health standards. This study highlights potential risks to the public\u27s health for seafood consumers by providing valuable information on heavy metal contamination in blue swimming crabs from the United Arab Emirates. Additionally, research closes a significant knowledge gap on the sex-specific bioaccumulation patterns of certain potentially harmful elements in blue swimming crabs, suggesting that male and female crabs accumulate different heavy metals at different rates. This study provides insightful information that will be useful for regulating food safety, facilitate strategic environmental monitoring to detect potentially harmful elements, and help regulate industrial pollution into marine ecosystems

EVALUATION OF FIELD GROWN GRAPEVINE GRAFTS FOR DROUGHT TOLERANCE UNDER WATER DEFICIT IRRIGATION IN THE ARID REGIONS OF UAE

Grapevines, among the most commercially significant fruit crops, are valued for their use in table grapes, raisins, and winemaking but are highly vulnerable to abiotic stresses such as drought, heat, and salinity. This study investigated the morphological, physiological, biochemical, and transcriptomic responses of grafted grapevines to drought stress, emphasizing rootstock-scion interactions. Grafting experiments were conducted with three rootstocks (Ramsey, RU140, and Paulsen) and table grape varieties (Thomson Seedless, Crimson Seedless, and Flame Seedless), with five combinations as Flame seedless × Ramsey (V1), Thompson seedless × Ramsey (V2), Crimson seedless × R110 (V3), Crimson seedless × Ramsey (V4) and Thompson seedless × P1103 (V5) under irrigation regimes of 100%, 75%, and 50% field capacity to simulate moisture stress. Results demonstrated the pivotal role of amino acids, including proline, cysteine, and arginine, in drought stress tolerance. Although several amino acids contribute to stress tolerance, cysteine and arginine play crucial roles with an increase in V2, V3, and V5 grafts, the former concomitant with downregulation of the chlorophyllase gene restricting chlorophyll pigment degradation, corresponds with increased nitrogen uptake while the latter as precursor amino acid involved in direct pathway for polyamine biosynthesis found in grafts are involved in various metabolic processes with anti-senescence and anti-stress effects by maintaining the integrity of the plasma membrane system. Phenylalanine was associated with enhanced photosynthetic activity through increased nitrogen and magnesium uptake, while glutamate, derived from nitrogen metabolism, supported stress tolerance in specific graft combinations. The antioxidant defense system, particularly the activities of CAT, SOD, and APX enzymes, effectively scavenged reactive oxygen species, maintaining redox balance and cellular water status. Hormonal dynamics, especially the interaction between ABA and GA3, revealed distinct antagonistic behavior, with cytokinin levels modulated by rootstock performance under soil moisture stress. Elevated glucose, glycine betaine, and macro and micronutrient accumulation further supported the physiological adjustments to deficit irrigation. Physiological traits such as net photosynthetic rate, stomatal conductance, and transpiration efficiency indicated enhanced water-use efficiency in specific grafts, particularly under 50% field capacity, correlating with increased biomass production. Scanning electron microscopy revealed the role of mineral elements, including calcium, in extracellular matrix formation, stomatal behavior, and trichome development under drought stress. Proline, arginine metabolism, and H₂O₂ detoxification are the main topics of this study\u27s transcriptome and metabolic analyses of Thompson Seedless * Ramsey grafted grapevines under drought stress. AREB1, AREB2, and NAC transcription factors were significantly upregulated, according to RNA sequencing, which encouraged proline buildup. Nitrogen recycling was supported by increased expression of ornithine aminotransferase (OAT), which connected proline production to arginine metabolism. Increased H₂O₂ levels improved ROS detoxification by activating antioxidant defences (SOD, POD, and CAT). Clear metabolic and transcriptomic changes were shown by the differential grouping of the stress and control samples, which was confirmed by Principal Component Analysis (PCA). This comprehensive study validates the significant role of rootstock-scion interactions in modulating drought-responsive mechanisms in grapevines. The findings provide valuable insights into the development of stress-resilient grafting strategies, enabling sustainable viticulture in arid and water-scarce regions

OVERCOMING MOTOR IMAGERY BCI ILLITERACY: ADAPTIVE DECODING AND KNOWLEDGE TRANSFER IN EEG-BASED BRAIN-COMPUTER INTERFACES

Brain Computer Interface (BCI), Also known as brain-machine interface (BMI) is a mean of controlling machines without the need to activate peripheral nerves or muscles. It has received the attention of research for decades. Motor imagery-based BCI is a paradigm that is characterized by its user friendliness where users can generate control commands at their freewill, without waiting for a que from the BCI module. Motor imagery brain–computer interface (MI–BCI) has considerable potential in increasing the quality of the lives for people with mobility impairment and the healthy ones as well. Though, its diffusion in application still has many pitfalls due to different limitations. The decoding of the signal, typically EEG, requires frequent calibration to maintain an acceptable accuracy threshold. Those limitations stem from many factors related to the nature of the signal, availability of training examples, and user related aspects. BCI-illiteracy is one of the open challenges that have been in literature for decades. This dissertation addresses the motor imager BCI-illiteracy by investigating the effect of Riemannian adaptive decoding and transfer learning on the performance of the classification accuracy. It introduces a variety of methods including supervised, unsupervised, and rebiased decoding of EEG signals. Also, it uses statistical methods to investigate the relationship between the motor execution and motor imagery in an endeavor to reframe the BCI-illiteracy. Finally, it transfers the domain knowledge between motor execution and motor imagery reducing the need for model calibration on motor imagery examples. The transfer of knowledge used resembles a straight forward and simple transfer approach where the weights of the class prototype presented a noticeable improvement with zero calibration. The methods presented in this dissertation contribute to the literature by reframing the BCI-illiteracy from an unprecedented approach by comparing the accuracy of motor imagery and motor execution as well. This dissertation paves the road towards having more reliable user-centered BCIs and cater for better understating and overcoming of BCI-illiteracy
