قلق الخطاب: رحلة في تاريخ تحليل الخطاب من خلال أعمال ميشيل بيشو
Authors: بدر الدين القاسمي
Published: September 2023

استهدف مالديدي تحديد ظروف نشأة نظرية تحليل الخطاب والسياق الأيديولوجي والمعرفي الذي احتضنها. وقد انطلق في ذلك من الظرفية التي أسهمت في تأسيس لبناتها ومفاهيمها الأولى، ليفترض بعد ذلك أن آلة تحليل الخطاب متشعبة ومتداخلة الروافد؛ لأنها كنظرية ظهرت في فترة تميزت بتواجد اللسانيات البنيوية والتوليدية، والمادية التاريخية خصوصًا مع التوسير ومبحث الإستوغرافيا زيادة على التفكيكية، ليقف أخيرًا عند أهم المراحل الإبيستيمولوجية التي مر منها تشكيل هذا المبحث. وقد خلص بشكل عام إلى كون مشيل بيشو يرفض أن يتم اختزال تحليل الخطاب أو إدراجه ضمن مبحث آخر، بل كان يتطلع الى إبرازه كنظرية مستقلة قائمة الذات لها مفاهيمها ومنهجها وجهازها التحليلي وموضوع بحث محدد، أي تخصص علمي. لكن مع تلاشي الوهم العلمي، صار تحليل الخطاب تخصصًا تفسيريًّا من دون برنامج أو منهجية محددة، مما جعل وضعه إشكاليًّا.
ESTIMATION OF THE CENTRAL MOMENTS OF A RANDOM VECTOR BASED ON THE DEFINITION OF THE POWER OF A VECTOR
Authors: Budny Katarzyna
Published: September 2023

The moments of a random vector based on the definition of the power of a vector, proposed by J. Tatar, are scalar and vector characteristics of a multivariate distribution. Analogously to the univariate case, we distinguish the uncorrected and the central moments of a random vector. Other characteristics of a multivariate distribution, i.e. an index of skewness and kurtosis, have been introduced by using the central moments of a random vector. For the application of the mentioned quantities for the analysis of multivariate empirical data, it appears desirable to construct their respective estimators. This paper presents the consistent estimators of the central moments of a random vector, for which essential characteristics have been found, such as a mean vector and a mean squared error. In these formulas, the relevant orders of approximation have been taken into account.

Authors: Roszko-Wójtowicz Elżbieta , Białek Jacek
Published: September 2023

The aim of the article is to work out a synthetic measure for estimating country’s innovation potential (CIP) of EU economies. For the purpose of the research, data from the European Statistical Office (Eurostat) are used and several indicators are organized by four different areas of analysis, i.e. investment expenditure, education, labour market and effects. Applying multi-dimensional statistics allows us to reduce the primary set of diagnostics variables and, simultaneously, identify those which best describe the potential. The final step is linear ordering of EU countries according to their innovative potential on the basis of CIP synthetic measure. The rating is compared with other ratings based on the recognized Summary Innovation Index and Global Innovation Index. The main conclusion is that the methodology of innovativeness assessment remains an open issue and requires further research. The most important task is the selection of indicators, followed by statistical verification in relation to their importance to innovativeness. The results show that there is a tendency to between the author’s ratings and other already published ratings of innovativeness.
El estudio retrospectivo de cohorte durante la investigación de campo de una epidemia
Authors: Cardenas Victor
Published: September 2023

Los estudios de cohortes retrospectivos en el contexto de las investigaciones epidemiológicas de campo, no reciben suficiente atención en la mayoría de los textos de epidemiología, a pesar de ser los más comúnmente empleados. Además, se argumenta erróneamente que el estudio de casos y controles debería utilizarse con más frecuencia. Repaso las indicaciones en las que el estudio de cohortes retrospectivo es más apropiado: la identificación de una población de riesgo que pueda estudiarse mediante empadronamiento o muestreo y que experimente una tasa de ataque considerable, digamos del 10%. También abordo otras cuestiones metodológicas sobre las mediciones de la exposición y la aparición de la enfermedad, el tamaño de la muestra necesario y el análisis de los datos de un estudio de cohortes retrospectivo.
A Statistical Approach for Study of Roundness in Commercially Produced Round Metal Bars
Authors: Roy Sanjib , Pal Arun Kiran
Published: September 2023

Commercially produced ferrous and non-ferrous metal round bars are available at various sizes. These bars have tremendous engineering use in multiple areas like automobile, aerospace, power, manufacturing, paper, printing, packaging and construction industries. Due to its wide range of utility of round bars, it is naturally pertinent to understand and ascertain quality aspect of these bars. Quite often it has been observed that round bars as available are not completely geometrically round at various sections along the length, also straightness is also somewhat compromised. Therefore, it is necessary to check the uniformity of diameters at various sections. In this paper statistical process control has been used to ascertain whether such round bars as commercially available can be utilized for industrial application or not. Control limits in terms of diameter measurement along the length of bars help to evaluate the characteristics of data variation which is needed to take decision about confirmation of utility of commercially produced bars

Just finished reading Small Pieces Loosely Joined. It's a fabulous essay on the nature of the Web. The more I read it the more it confirms my fear that most people talking about biological taxonomy and biodiversity on the Web simply don't "get" the Web. Adopting the Web successfully will require a willingness to accept error, ambiguity, and downplaying "expertise" and "authority". It will be interesting to see what happens.

Authors: . Pitambara , Shukla Y.M. , Mehta Brijesh K. , Parmar D.J.
Published: September 2023

In the present study, forty eight sub-tropical maize inbreds were analyzed for grain yield and yield attributing traits along with micronutrients content. Genotypic differences were significant among the maize inbreds for all the traits under study. Kernel Fe concentration ranged from 14.23 to 38.08 mg/kg, while kernel Zn concentration varied from 11.61 to 39.41 mg/kg. Kernel copper (Cu) and manganese (Mn) content ranged from 1.34 to 4.31 mg/kg and 2.05 to 9.83 mg/kg, respectively. Significant positive correlation was observed among the kernel Fe, Zn, Cu and Mn, indicating the possibility of their simultaneous improvement. For kernel Fe concentration, GWL28 (38.08 mg/kg) and CML296 (33.78 mg/kg) were found to be the best genotypes. In case of Zn content, GWL28 (39.41 mg/kg) and GYL10 (35.41 mg/kg) were the best inbreds. Genetic diversity based on all the four micronutrients grouped 48 inbreds into five major clusters. The highest genetic dissimilarity was observed between CM133 and CML251, while CML251 and CML293 showed the lowest dissimilarity. Rank summation index identified CML296, GYL1 and CML269 as first three best inbreds for kernel micronutrients content and grain yield. The promising inbreds identified here would be useful for developing biofortified maize hybrids enriched with micronutrients
Understanding physiological and molecular adaptations of three diverse halophytic grasses under saline and sodic stresses
Authors: Lata Charu , Kumar Ashwani , Kumar Naresh , Kaur Gurpreet , Rani Sulekha , Mann Anita
Published: September 2023

Physiological and biochemical analyses of three halophytes were conducted to explore their tolerance and phytoremediation potential. The halophytes Urochondra setulosa, Sporobolus marginatus and Leptochloa fusca were categorised based on gas exchange attributes, antioxidant system, biomass production under soil salinity (ECe 30-50 dS/m) and sodicity (pH 9.5-10). L. fusca and S. marginatus produced slightly higher biomass under the sodic condition of pH 9.5, while in U. setulosa, it increased under salinity stress. Under sodic conditions, L. fusca showed less reduction in potassium content and maintained a higher K+/Na+ ratio in their leaf tissues. A maximum decrease in net photosynthesis was observed in L. fusca (28.55%) at ECe ~ 50 dS m-1 while minimum in S. marginatus (13.73%) at pH ~ 10.0. Comparatively, U. setulosa showed higher stomatal conductance and transpiration rate than L. fusca and S. marginatus. At the highest pH and salinity, the antioxidant activities of enzymes APX, SOD, GR and POX increased in all three halophytes. Quantitative expression of MnSOD, NHX1 and FuSOS1 genes in all three halophytes increased with salt stresses. Based on these indicators, these halophytes were categorised as salt-tolerant or alkaline-stress-tolerant.

Authors: Atri Ashlesha , Bhardwaj N. R. , Roy A.K. , Kaur Amrinder
Published: September 2023

Downy mildew incited by Sclerospora graminicola is the main hurdle in the successful cultivation of pearl millet and is capable of causing more than 60% losses in terms of grain and fodder yields. The disease could be managed by fungicide applications but due to several associated environmental and health-related issues, there was a necessity to formulate some eco-friendly measures for downy mildew management. Thus attempts were made to find out the usefulness of three biocontrol agents (Bacillus subtilis, Pseudomonas fluorescens and Trichoderma viride) and two fungicides (mancozeb 64% + metalaxyl 4% and metalaxyl) under field conditions for three seasons (2017-2019) against downy mildew. The least downy mildew incidence (14.37%) was observed with seed treatment + foliar spray of B. subtilis as compared to untreated control (31.30%) with 54.10% disease reduction followed by seed treatment + foliar spray of P. fluorescens (17.58% disease incidence) with 43.82% disease control. The same treatments were significantly superior over others in increasing the green fodder yield by 56.59 and 40.79% respectively. Another treatment proven effective was seed treatment + two foliar sprays of T. viride which provided more than 43% reduction in downy mildew incidence as compared to chemical check which provided 30% disease control and increase in green fodder yield. These findings advocated the potential use of biocontrol agents against downy mildew of pearl millet in an eco-friendly manner.
Production potential, quality and thermal utilization of fodder pearl millet varieties under different sowing environments in irrigated conditions of central Punjab in India
Authors: Kaur Maninder , Oberoi Harpreet  Kaur
Published: September 2023

An experiment was conducted at Punjab Agricultural University, Ludhiana, India during two consecutive years i.e., 2019 and 2020 to study the effect of dates of sowing and pearl millet varieties on productivity and quality of green fodder and thermal utilization by the crop. The field experiment was laid-out in a split plot design with seven dates of sowing (1st April, 15th April, 1st May, 1st June, 15th June, 1st July and 15th July) in main plots and two varieties of pearl millet (PCB 165 and FBC 16) in sub plots with three replicates. Significantly highest green fodder yield (69.3 t/ha) was obtained with 1st June sowing which was probably on account of maximum plant height and number of tillers. The 1st June sown crop also recorded significantly highest dry matter and crude protein yield of 15.0 t/ha and 0.95 t/ha, respectively. Both advanced and delayed sowings recorded significant reduction in green fodder and dry matter yield. The crop sown on 1st May required maximum growing degree days, photo-thermal and helio thermal units at 50% flowering stage and sowing done early as well as late recorded significant reduction in these agro-climatic indices. Across different dates of sowing, PCB 165 registered an increase of 11.9 and 12.4% in green fodder and dry matter yields, respectively over FBC 16 due to higher accumulation of growing degree days, photo-thermal and helio thermal units for 50% flowering stage. The interaction effect showed that PCB 165 sown on 1st May, 1st and 15th June recorded significantly more green fodder yield over FBC 16, while the differences were narrow and non-significant at other dates of sowing.

Authors: Ji Chenxi , Stamopoulos Stergios
Published: September 2023

Maritime decarbonization is a particularly complex challenge with multiple pathways at various technological and operational readiness levels. This work conducted a holistic analysis of green shipping corridors by the well-to-wake lifecycle emission analysis and lifecycle cost evaluation. The index of GHG Abatement Cost (GAC) was proposed to quantitatively investigate the cost-effective fuel pathways toward the long-term IMO decarbonization goal from the perspective of WtW process. Green bio-Methanol, Green Ammonia, and Wind based Green Liquid Hydrogen were verified to be the most rewarding pathways to save GHG emissions. The Rotterdam-Singapore GSC case study was conducted to evaluate the GWP-related gas emission inventory for shipping voyages and the annual cost performance of the different green pathways. The green bio-methanol pathway has been finalized to be the optimum one under current technology and infrastructure readiness level.
Noise and Vibration Design of Vessels – A Case Study of the OLLIS Class Ferries
Authors: Spence Jesse , Page Chris
Published: September 2023

A ship is a complex system that utilizes multiple mechanical, electrical, and hydraulic systems during its operation. All these systems can generate noise and vibration, which if not properly addressed during design and construction may cause passenger and crew discomfort, safety issues related to degradation in voice communications, and even structural damage. The noise and vibration generated by a ship is a direct reflection of the quality of the design and construction of the vessel; lower noise and vibration environments will improve passenger experiences, improve quality of life and retention of the crew, and increase mission effectiveness. However, a vessel’s noise and vibration do not need to be left to chance. Engineering tools and processes can be used throughout the vessel’s design and construction which will produce a vessel with low noise and vibration.

This paper presents a case study of the three new Staten Island OLLIS Class Ferries built by Eastern Shipbuilding Group. Pertinent details of the acoustic design and support efforts performed during Detail Design, construction, and delivery are provided. Early in the Detail Design phase, predictions were performed that identified several potential issues with meeting the desired noise and vibration goals. Various efforts were performed to identify appropriate means for mitigation using computer aided design tools. Solutions were developed to allow the vessel to meet its acoustic objectives, though it was known that noise and vibration would be very close to the limits. Various efforts were also performed during construction and compliance testing at sea trials to help the vessel meet its objectives, including ‘tuning’ of the propulsion system and the identification of an odd bearing issue that caused elevated noise. This paper describes the modeling, design, construction support, and testing efforts that were performed, along with details of the primary issues that were identified and solutions.
Creation of a Ride Control Algorithm Using a Neural Network
Authors: Murphy Kyle L. , Heilshorn Eric J.
Published: September 2023

Ride control systems are often implemented to reduce vessel motions. However, modern ride control systems are prone to experiencing a phase lag between the wave-induced motions and the control system’s actuation. The phase lag limits the system’s ability to dampen vessel motions and reduces the system’s effectiveness. To investigate a possible improvement to modern systems, an artificial neural network-based controller, trained by potential flow simulations, was used to prescribe the optimum future actuation of a ride control system. By prescribing the optimum future actuation in anticipation of system delays, phase lag can be mitigated.

Published: September 2023

The objective of NSRP Research Announcement Project RA 21-11 is to deliver a set of ship and offshore platform design tools based in first principles and physics simulations that can be effectively used by ship design teams during the early stages of the design when options can be explored and considered by the team. This includes design space exploration such as evaluating design excursions of making modest changes in structural weight that have minimal or positive impact on ship construction cost or lightship weight yet can have significant impacts on hull girder strength to handle heavy weather with reduced damage and/or increase the structure’s fatigue service life. It is time for higher-fidelity design methods for ship structures to be implemented into the early-stage ship design process to empower the design team to conduct serious engineering evaluations of alternative structural designs that pursue lean design and least weight while ensuring that structural design criteria are met.
Ocean Wave Harvesting for Supplemental Powering of a Small Autonomous Boat
Authors: Kokro Aspa P. , Datla Raju , Hajj Muhammad
Published: September 2023

This study presents the concept of a small autonomous catamaran for operation in remote offshore areas for long duration. The relative linear motion between the hulls and the main deck is converted into a rotational motion of an electrical generator to harvest wave energy for supplemental powering and improving the overall energy efficiency of the craft. The design of “DavLab” catamaran is optimized by matching the natural undamped frequency of the system to the frequency of dominant waves for a top referenced heaving absorber. In addition, numerical simulation results showed that increasing the design waterline reduces vertical motion, and the hull responses increase with increasing length to beam ratio and decreasing beam to draft ratio. Consequently, the combined motion at the power take-off system positions were increased by selecting a slender body with L/B = 5.88 and large draft B/T = 1.89 for large motion at operating conditions. In head seas, the required power for a 1/3 scale model at Froude number equal to 0.6 is predicted about 3.5 W. For supplemental powering with wave energy harvesting, the wave run predictions in head seas for a dominant period of 2 seconds and significant wave height of 0.2 m were evaluated at two model speeds, namely Vm0 = 0 m/s and Vm1 = 2.66 m/s corresponding to Froude number 0 and 0.6. Predictions for maximum generated power are 4.7 W and 12.7 W at Vm0 and Vm1 respectively. Therefore, the 1/3 scale model of the Catamaran suspension is to be built and tested in Davidson Laboratory Towing Tank #3 in regular and irregular head seas.

Published: September 2023

Large-scale carbon capture and sequestration is confronted by a multitude of factors, both technical and financial in nature. Of these issues, the challenge of long-term storage solutions remains at the forefront – and especially when an economically viable solution is desired. Subsea depleted reservoirs and saline aquifers have been proposed as potential solutions for this problem. This paper details the development of a design space characterization for the offshore carbon sequestration (OCS) problem, where the trade-offs between potential solution parameters are examined and significant variables to the decision-making process are identified. This has been completed without the constraint of geographical location, and identifies the data required to analyze a specific region of interest. A case study is presented where the characterization is applied to a proposed floating storage and injection unit (FSIU) which has been carried through a preliminary design. Through the case study, the benefits of developing a design space characterization for complex problems are clearly shown – as the design was executed on schedule, with limited prior experience, and with no emergent design failures.

Published: September 2023

Microbial community, host gene expression, and pathological image in the tumor microenvironment (TME) are interrelated, and they can provide valuable insights into tumor heterogeneity. However, the complex and important interconnection patterns among these multimodal omics in pan-cancer remain far from being elucidated. Here, we developed a framework for decoding the association among the microbial community, host gene expression, and pathological image in the TME for a broad spectrum of cancers in multiple independent cohorts. Our results indicated three types of microbe-expression-image triplet (MEI-triplet) interplay patterns in human cancers. MEI1, including esophageal cancer (ESCA) and pancreatic adenocarcinoma (PAAD), was characterized by no significant intratumoral microbe-host interaction. MEI2, which included eight cancers (liver hepatocellular carcinoma [LIHC] is one of these), was characterized by a strong association of tumor microbiota and host gene expression, but changes in the TME were not reflected in pathological images. Meanwhile, MEI3, including colorectal cancer (CRC), stomach adenocarcinoma (STAD), and lung squamous cell carcinoma (LUSC), was characterized by strong associations among tumor microbiota, host gene expression, and pathological images. Further experiments with validation datasets for several representative cancer types also supported these patterns. Out of the three MEI patterns, patients with MEI1 had the worst prognosis risk, followed by those with MEI3 and MEI2. Our findings provide new insights into tumor heterogeneity, which could assist with providing more precise diagnosis and prognosis assessment in clinics.
The Thought of “Three Religions in One” Reflected by Lin Zhaoen’s View of History
Authors:   Yixin Publisher, Liu Puchun , Wang Yibo
Published: September 2023

As a folk sect developed by a group of scholars, the “Three-in-One” differs from other sects such as the Luozu Religion and the Vacuum Religion, whose main doctrines are based on Buddhism and Taoism, with a distinctive “Confucianism-based” character. The most striking part of the theory of its founder, Lin Zhaoen, is that he uses Confucianism to unify Confucianism, Buddhism, and Taoism, and divides the three religions into an order of establishment, initiation, and extreme rule. What is striking is that Lin Zhaoen has used his historical commentary to expound on the “three religions in one”. The historical perspective embodied in his commentary reflects his unique theory of “three religions in Confucianism”, and to a certain extent, he has broken through the traditional Confucianism of reverence for the past, laying a firm theoretical foundation for the development of his sect.
Research on the Implementation Path of China’s Higher Education Institutions’ Participation in Legal Aid
Authors:   Yixin Publisher, Yan Feifei
Published: September 2023

The Legal Aid Law of the People’s Republic of China stipulates that universities should engage in legal aid work under the guidance of the judicial administrative department, but it does not specify the implementation path for universities to participate in legal aid. Currently, the common issues that exist in the participation of universities in legal aid include lack of management mechanisms, lack of funding sources, limited assistance scope, and lack of incentive mechanisms, which severely limit the role of universities in legal aid. This article focuses on the current situation of universities’ participation in legal aid, analyzing the reasons for problems in the process of universities’ participation in legal aid from multiple perspectives, and proposing feasible suggestions for more efficient participation in legal aid, so as to enable universities to play their due role in legal aid and contribute more to the construction of the rule of law.

Limbah kotoran ternak, seperti kotoran ayam dan kotoran domba merupakan salah satu limbah organik yang menimbulkan permasalahan lingkungan, seperti pencemaran bau tak sedap dan menjadi medium perkembangbiakan organisme patogen yang berbahaya untuk kesehatan. Lalat tentara hitam (black soldier fly [BSF]) diketahui memiliki kemampuan untuk mengonversi beragam jenis limbah organik secara efektif termasuk limbah kotoran ternak. Penelitian ini bertujuan mengetahui potensi reproduksi dan morfometri BSF yang dipelihara pada kotoran domba dan kotoran ayam. Penelitian ini merupakan penelitian eksperimental menggunakan rancangan acak lengkap dengan tiga perlakuan, yaitu perlakuan kotoran ayam, kotoran domba, dan pakan ayam (kontrol) dengan masing-masing lima ulangan. Parameter yang diukur meliputi waktu perkembangan, morfometri, jumlah pasangan yang kawin, dan fekunditas. Perlakuan kotoran domba memiliki waktu perkembangan yang paling tinggi di antara perlakuan lainnya. Morfometri BSF dewasa yang dipelihara pada pakan ayam mempunyai nilai morfometri tertinggi dibandingkan kotoran ayam dan kotoran domba. BSF yang dipelihara dengan pakan ayam mempunyai jumlah pasangan kawin terbanyak (44 pasang) dibandingkan yang diberi kotoran domba (31 pasang) dan kotoran ayam (20 pasang). Fekunditas telur tertinggi terdapat pada BSF yang diberi pakan ayam (3.535 butir). Hal ini menunjukkan bahwa kotoran ayam dan kotoran domba cocok sebagai media pertumbuhan BSF, namun potensi reproduksinya lebih rendah dibandingkan pakan ayam.

The crocodiles are one of the largest living reptiles representing the majority of the ancient classes of reptilians which are far reaching and dependent on the deep oceanic environments of the tropical and sub-tropical locales. In expansion to their biological significance and recognizable proof as the key stone old species, they serve exceptionally critical economic role for human civilization. Crocodile meat is not only delicious, it is anti-arthritic, antiinflammatory, anti-arrhythmic, anti-thrombotic, anti-atherosclerotic, and anti-carcinogenic for human being. However, most of the populations of the species have been depleted in their ranges due to over harvesting for diversified employment settlement with special regard to their highly valued skin and oil. Consequently, out of 23 living species, nearly half of them are recorded in several categories of Red Data List as debilitated species and currently facing severe threats for survival. The purpose of the Chittagong zoo, Bangladesh is recreation, exhibition, conservation, education and research on wildlife. The current study aimed to focus the morphometry, habitat, nutrition, health and reproduction of the marsh crocodile (Crocodyluspalustris) conserved in the Chittagong zoo, Bangladesh.

Globalization demands something new and natural. Natural pigments from microalgae could be something like that. However, it is a long way from a Petri dish to market. However, it is going to happen. So, knowing the pigment concentration among different species is necessary because of its significant role in the global market. The present study is designed to estimate the Chlorophylls, carotenoids and phycobiliproteins (Allophycocyanin, Phycocyanin and Phycoerythrin) contents of four (4) different indigenous marine microalgae species i.e. Chlorella sp., Chaetoceros sp., Nannochloropsis sp. and Tetraselmis sp. The result showed significant differences in the concentration of pigments among the species. However, Tetraselmis sp. produced a significantly higher amount of chlorophyll a (2.68 µg/L ± 0.04), and Chlorophyll b (1.23±0.02 µg/L) where Chaetoceros sp. had higher chlorophyll c (0.29±0.01 µg/L) among all the species. In the case of carotenoids, Chlorella sp. produced the lowest carotenoids (0.56±0.02 µg/L), where the other three showed no significant difference. Allophycocyanin and phycoerythrin were reported significantly higher (0.0197±0.0006 µg/L) and (0.0029 ± 0.0002 µg/L) in Nannochloropsis sp. rather than other three species where no significant difference was found in the concentrations of phycocyanin among all the species. Whatever the amount is, these microalgae are important because of their novel features. The study's findings will help the producer select a definite species according to their target and needs.

The adoption of a data-driven pedagogy is rapidly occurring among Open distance and e-learning institutions. In certain regions, individuals engaged in the field of education encounter obstacles related to data availability and network coverage, despite the existence of digital tools utilized by educators and online learners to enhance the teaching and learning process. This research study employs a social-constructivist theoretical framework as its research paradigm. Additionally, it adopts an interpretivist perspective within the social constructivist paradigm to gather insights from participants who originate from diverse life contexts. The researcher found that employing a mixed methods research methodology, which combines both quantitative and qualitative methods, was the most appropriate choice for their study. The utilization of both study approaches enabled the researcher to triangulate the collected results, hence enhancing the robustness of the findings. The quantitative portion of the study involved a sample size of forty participants. A questionnaire was employed as a means of gathering information, and subsequent data analysis was conducted utilizing charts and tables.  The qualitative component of the study involved conducting interviews with a total of twelve focus groups. The acquired data was subjected to thematic analysis. The findings indicate that a significant proportion of pupils, even those residing in urban and rural areas, derived advantages from the implementation of data-driven teachingv
