Reflexive Pedagogy: A Closer Look at Saudi College Students’ Responses to English Poetry
Get PDFThis study aims to explore Saudi college students’ analytical abilities by focusing on their engagement with English poetry through reflective learning practices. The study employed a multimodal approach and multimedia to interpret poetry, focusing on enhancing students\u27 understanding of poetry while also examining the effectiveness of this instructional method. The poems selected for the study are from the British Romantic Period (1789–1830). It is a strategic implementation of a culturally appropriate pedagogy that utilises visual language to interpret poems in English. Independently constructing their own videos provided students with a chance to replace traditional written interpretation of poems in the classroom. Allowing multilingual students to communicate and express emotions visually gives them access to their creative potential, from which they can construct more meaningful interpretations. The study demonstrates through their personalised videos, that Saudi student are open to composing and explorations using technology and multimedia that liberate them from traditional teaching techniques and allow them to unlock their interpretive skills and represent their interpretations in original ways. Furthermore, these findings might also have greater relevance to wider debates on extending the use of technology and multimedia as a key element for educators hoping to engage students with reading and responding to poetry in a second language.

QUADRATIC STOCHASTIC PROCESSES: ALGEBRAIC STRUCTURES AND THEIR APPLICATIONS
Get PDFThis research focuses on the algebraic structures of the Quadratic Stochastic Processes (). In this work, we first study - Quadratic Stochastic Operators () linked to the partition P3. We simultaneously discuss the dynamics of the obtained . Moreover, algebraic structure of the associated genetic algebra is studied. Further, we build Quadratic Stochastic Processes () using the given Markov processes. Consequently, we obtain an ordinary differential equation for the resultant Quadratic Stochastic Processes (). Besides, we apply the solution of this ordinary differential equation for the option pricing problem. Thereafter, we construct Quadratic Stochastic Processes () in three-dimensional space by utilizing the parameters of the Susceptible-Infected-Recovered () model. In addition, we investigate the algebraic properties for 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 Quadratic Stochastic Process () modulated Geometric Brownian Motion (GBM) model. We also analyze the Radon-Nikodym derivative of the Equivalent Martingale Measure () with respect to the historic probability . Ultimately, we obtain an infinitesimal generator which facilitates numerical simulations of the non-Markovian and stock price processes
A DATA-DRIVEN RECOMMENDATION SYSTEM FOR SELECTING THE APPROPRIATE MODE OF LEARNING AND INSTRUCTIONAL TOOLS BASED ON COURSE CHARACTERISTICS
Get PDFThe rapid transformation of educational delivery methods during the COVID-19 pandemic required institutions to transition between online, hybrid, and offline learning approaches, creating both challenges and opportunities for educators and students. While online and hybrid learning modes ensured continuity, their effectiveness across different course types remained uncertain. This thesis addresses this gap by developing a datadriven recommendation framework that predicts Course Learning Outcome (CLO) achievement scores using regression, and recommends the most appropriate learning mode (online, hybrid, or offline) along with instructional tools based on course characteristics. This study analyzed 100 undergraduate and postgraduate courses from the College of Information Technology (CIT) at the UAEU, offered across 1165 course sections, spanning five academic semesters (Fall 2020–Fall 2023). The dataset derived from official course portfolios, captures key attributes such as teaching methodologies, assessment strategies, practical engagement, and performance metrics such as CLO achievement trends across three departments: Computer Science & Software Engineering, Computer & Network Engineering, and Information Systems & Security.Machine learning approaches were used to predict CLO achievement, with many algorithms explored throughout the modeling phase. Among the models examined, the Gradient Boosting Regressor outperformed Random Forest and Linear Regression in terms of prediction accuracy. A rule-based recommendation system was created to match course requirements with suitable delivery modalities to convert these predictions into workable tactics. For example, hands-on learning environments were linked with practical courses, whereas online or hybrid forms were more appropriate for theoretical subjects. These results provide a data-driven method for instructional planning which assists institutions in creating more individualized and successful learning programs
DETECTION AND QUANTITATION OF DRUGS AND PESTICIDES IN FOOD PRODUCTS OF THE UAE (DATES AND CAMEL MILK) BY LIQUID CHROMATOGRAPHIC TECHNIQUES
Get PDFIn this thesis the detection and quantification of the traces of multi-residue pesticides in 26 dates samples as well as the presence of the anthelmintic drug thiabendazole in pasteurized commercial milk consumed in the United Arab Emirates is examined. The main objective of this thesis is two folds. First is to determine whether a selected group of 12 pesticides of 8 different groups- in the case of dates- and the drug thiabendazole-in case of camel milk- exists in the randomly collected samples of corresponding matrices. Second, is to quantify these compounds and compare their amount to the established maximum residue limits (MRL)set by the European Commission according to regulation (EU) 2020/585. Two different techniques were used for detection and the quantification, namely the standard addition method using HPLC-FLD instrument in case of thiabendazole in camel milk and the internal standard method using LC–ESI (+)-MS/MS in the case of the12 pesticides in dates. Thiabendazole extraction from camel milk samples was based on liquid-liquid extraction while quick, easy, cheap, effective, rugged, safe (QuEChERS) technique was used for dates sample preparation. Results shows that EPN, Azoxystrobin and Metalaxyl concentrations are higher than their corresponding MRLs (10 ppb in the case of the first two pesticides and 50 ppb for Metalaxyl) in some of the dates real samples while Carosulfan was consistently higher than its 10 ppb in more than half of the 25 collected real samples. Thiabendazole conversely is below the set MRL in all milk real samples. The LC–ESI (+)-MS/MS developed method could detect pesticides in the range of sub ppb (0.5 ppb) for 11 out of 12 pesticides while the HPLC-FLD detected Thiabendazole as low as 20 ppb. The results obtained by the developed LC–ESI (+)-MS/MS and HPLC-FLD methods can provide a strong basis for future instructions to be set by monitoring and regulatory bodies for ensuring quality control of food products such as camel milk and dates consumed in the UAE

شطب الدعوى واعتبارها كأن لم تكن وفقاً لآخر التعديلات الإجرائية المستحدثة بنظام المرافعات الشرعية السعودي وقانون المرافعات المصري دراسة تحليلية مقارنة
Get PDFAbstract
This study aims to present a contemporary analysis of the updated procedural framework regarding the rules governing the absence of litigants from legal proceedings and its implications from the aspect of striking out a case and considering it void ab initio. The study has been carried out within the scope of the Saudi Law of Sharia Procedure analyzed in comparison with the Egyptian Procedural Law as amended. This study primarily aims to establish a comprehensive understanding of the legal nature of striking out a lawsuit and considering it void ab initio due to the absence of litigants in light of the amended legal provisions. Additionally, it also aims to assess the efficacy and sufficiency of the legislative solutions established by these legal provisions. This study consists of three analyses: the first analyzes the concept of attendance in legal proceedings and the criteria for default litigation/judgment; the second analyzes the concept of striking out a lawsuit and its prerequisites and effects, and also the concept of reinstating a struck-out lawsuit and its mechanism and timeline; and the third analyzes the criteria and implications of ruling a lawsuit as void ab initio and the limits of judicial discretion in this regard. The most important findings and recommendations derived from the study are as follows:
1- A new rule has been established regarding the concept of default litigation, whereby: a lawsuit is only considered default in relation to a litigant who can reasonably be assumed unaware of its existence, i.e., the litigant who lacks all circumstances that would ensure their certain knowledge of the lawsuit\u27s existence.
2- The preferable and fairer approach is to base the striking out of a lawsuit due to the absence of both litigants and not solely due to the absence of the plaintiff, while granting each of them the right to reinstate the lawsuit from its struck-out state and the right to present excuses for their absence.
3. If the lawsuit is not reinstated within 60 days from the date of its striking out or if the litigants are absent after its reinstatement, it is considered void ab initio. If the plaintiff subsequently requests to proceed with the lawsuit, the Saudi judge shall sua sponte rule the lawsuit void ab initio as such a ruling pertains to public order. Whereas, the Egyptian judge may only rule to this effect upon a request by the defendant, as such a ruling pertains to the latter’s private interest.
4- The provisions of the procedural laws (Articles 49, 50, 55, 57, 59 of the Saudi law of Sharia Procedure and Article 82 of the Egyptian Procedural Law) require reconsideration and further legislative amendment to ensure the effective application of the rules regarding the striking out of lawsuits and to guarantee sound administration of justice.
ملخص البحث
تستهدف هذه الدراسة معالجة حديثة للتنظيم الإجرائي المستحدث لأحكام غياب الخصوم عن الحضور وأثره بصدد تقرير شطب الدعوى القضائية والحكم باعتبارها كأن لم تكن، وذلك في نطاق نظام المرافعات الشرعية السعودي، في إطار تحليلي مقارن بنصوص قانون المرافعات المصري المعدل. وقد استهدفت هذه الدراسة – ابتداءً - تكريس رؤية جامعة لماهية شطب الدعوى والحكم باعتبارها كان لم تكن إثرَ غياب الخصوم في ضوء النصوص المعدلة. كما استهدفت أيضاً، تقدير مدى نجاعة وحدود كفاية الحلول التشريعية التي كرستها هذه النصوص. وقد تشكلت الدراسة من مباحثٍ ثلاثة: عالج الأول منها ماهية الحضور، ومعيار الخصومة الغيابية. وتناول الثاني ماهية شطب الدعوى ومفترضاته، وأثره، وأيضاً ماهية تعجيل (إخراج) الدعوى من حالة الشطب، وآليته وميعاده. وعالج المبحث الثالث ضوابط وآثار الحكم باعتبار الدعوى كأن لم تكن، وحدود سلطة المحكمة في هذا الخصوص. ومن أبرز النتائج والتوصيات التي أسفرت عنها الدراسة، ما يلي:
1- ثمة قاعدة جديدة تكرّست بصدد ماهية الخصومة الغيابية؛ مؤداها: أنّ الخصومة لا تكون غيابية إلا بالنسبة للخصم الذي يصح افتراض جهله بوجودها فقط؛ أي الذي تنتفي كل فروض علمه اليقيني بقيام الخصومة.
2- الأَوْلَىَ قبولاً؛ والأكثر عدالةً؛ تأسيس قرار الشطب على غياب الخصمين معاً، وليس على غياب المدعي وحده، مع منح كلٍ منهما حق تعجيل الدعوى من حالة الشطب، وأيضاً الاعتداد بعذر كلٍ منهما حال غيابه.
3- إذا لم تُعَّجل الدعوى خلال 60 يوم من تاريخ شطبها، أو تغيب الخصوم بعد تعجيلها من الشطب، عُدَّت كأن لم تكن، فإذا طلب المدعي بعد ذلك السير فيها، حكم القاضي السعودي من تلقاء نفسه باعتبار الدعوى كأن لم تكن؛ لتعلق الحكم بالنظام العام، أمّا القاضي المصري فليس له أن يقضي بذلك إلا بناءً على طلب المدعى عليه؛ لتعلق الحكم بمصلحة الأخير الخاصة.
4- نصوص المرافعات (49، 50، 55 ، 57 ، 59 سعودي، و82 مصري ) تحتاج لإعادة نظر ومن ثمّ معالجة تشريعية جديدة؛ لضمان تفعيل أحكام شطب الدعوى؛ ولضمان حُسن سير العدالة
DIET, BIOACCUMULATION OF HEAVY METALS, AND POPULATION GENOMICS OF NARROW-BARRED SPANISH MACKEREL (SCOMBEROMORUS COMMERSON) FROM THE ARABIAN GULF
Get PDFMarine organisms are integral part of marine ecosystems, forming complex feeding interactions. Large predatory fish are especially important because they often govern food web structures through top-down influences. The narrow-barred Spanish mackerel (Scomberomorus commerson) is an ecologically and economically important fish species that feeds on small forage fish. The current study focuses on three aspects of the narrow-barred Spanish mackerel (diet, bioaccumulation of heavy metals and population genomics). This species is considered near-threatened, as its population has been declining due to anthropogenic stressors. The Arabian Gulf experiences continuous natural stressors, which are further exacerbated by human activities, impacting the marine ecosystem. The narrow-barred Spanish mackerel is an ecologically and economically valuable fish that remains less investigated. To assess the diet of S. commerson collected from two distant locations inside the Arabian Gulf (UAE and Iran), two different approaches were used: 1.) The gastrointestinal tract was physically inspected to identify various semi-intact prey species. 2.) DNA barcoding and phylogenetics, based on 16s rRNA, were employed to identify fish prey taxa. Based on both morphological and DNA barcoding analysis, the semi-intact prey species in the gastrointestinal tract consistently identified the primary prey as sardines (Sardinella spp.) and scads (Decapterus spp.). All the narrow-barred Spanish mackerel specimens sampled from both sites in the Gulf showed poor body condition based on the Fulton’s body index. Further research is required to understand the diet of the narrow-barred Spanish mackerel. Anthropogenic activities have increased the discharge of marine contaminants, threatening marine life. Small gulfs, such as the Arabian Gulf, are vulnerable to accumulating potentially toxic elements in marine species due to slow water exchange. The concentration of 21 elements was determined in the tissues of Scomberomorus commerson from Umm Al Quwain (United Arab Emirates) and Bandar Abbas (Iran). Chromium, copper, and iron exceeded internationally established maximum permissible limits. Sites could not be distinguished based on Principal Component Analyses of elements. Elevated Cu and Cr in muscle are of concern to marine species as well as humans. The Metal Pollution Index showed a significant difference between sites, with 20.34% and 100% of individuals suffering from high metal toxicity and poor body conditions, respectively. The Arabian Gulf is experiencing an increase in the discharge of industrial wastes. Implementation of strict policies to reduce the discharge of toxic substances is required to protect marine organisms and humans. Conservation of wildlife populations requires a thorough understanding of population structure and gene flow. Usually, when sampling is conducted for ecological studies, it is assumed that specimens are collected from one population. However, the obtained samples might be collected from more than one population, making it difficult to guide wildlife management with uncertainty regarding individuals from distinct populations. The Arabian Gulf is considered a living laboratory as it supports several coastal and marine ecosystems and is home to a wide range of fish species. However, the lack of genetic data, especially for fish populations, raises taxonomic uncertainty. Therefore, this study used advanced genomic tools to resolve these uncertainties by assessing the population structure, gene flow, and dispersal of the narrow-barred Spanish mackerel from the Arabian Gulf. The ddRAD sequencing, quality check-filtering of sequences, and analysis through genetic software reported that the narrow-barred Spanish mackerel collected from the eastern Arabian Gulf is a panmictic population with significantly low FST values. This study emphasizes the need for conservation, sustainable fisheries management, and stricter pollution control to ensure the long-term stability of the narrow-barred Spanish mackerel population in the Arabian Gulf ecosystem
