- Abstract
The 2021 EUROCALL conference engaged just under 250 speakers from 40 different countries. Cnam Paris and Sorbonne Université joined forces to host and organise the event despite the challenging context due to the COVID-19 pandemic. Originally programmed to be held on site in the heart of Paris, France, the EUROCALL organising team and executive committee agreed to opt for a blended and then for a fully online conference. The theme of the 2021 EUROCALL conference was "CALL & Professionalisation". This volume, a selection of 54 short papers by some of the EUROCALL 2021 presenters, offers a combination of research studies as well as practical examples fairly representative of the theme of the conference.

- Abstract
Designing standardized exams for EFL undergraduates is a matter of great concern in pedagogical practices that assess learners' academic achievements. This case study was conducted at Majmaah University, Saudi Arabia, to explore the significance of educational exam standardization and its impact on the process of implementation, leading to a balanced and equitable assessment of English language skills. During the study, 250 final English skill exam questions of two semesters were analyzed. A mixed-method approach using a questionnaire and Focused Group Discussion was adopted to collect relevant data. The quantitative data were analyzed using SPSS 16, and the qualitative data was processed by thematic analysis. The quantitative data results showed that questions were balanced, valid, and reliable in language skill exam papers designed for undergraduate English students. The qualitative data revealed four major themes -- standardization of questions, the efficacy of Bloom's taxonomy, assessment/evaluation, and alignment of the question with learning outcomes. These emerging themes highlighted the effectivness of standardizing exam papers, identified problems, and suggested ways of improvement. The study indicates that exams must be scrutinized for the sake of standardization in terms of maximum course coverage; the variety in the question item; clear, concise, and precise instructions; validity and reliability of exam papers; and the alignment of questions with the course and program learning outcomes to ensure the implementation of the revised Bloom's taxonomy. The study suggests, to generalize the results, that further investigation should be done in another Saudi university for the sake of comparison.

- Abstract
The Commission on International Adult Education (CIAE) of the American Association for Adult and Continuing Education (AAACE) provides a forum for the discussion of international issues related to adult education in general, as well as adult education in various countries around the globe. These papers are from the CIAE 2020 Virtual International Pre-Conference. The global aberration, called COVID-19, defined 2020 beyond national borders. COVID-19 reshaped the format of the 69th annual AAACE conference by replacing the traditional bustling human interaction with virtual meetings and presentations. These "Proceedings" contain 12 papers from 17 authors. The preeminence of COVID-19 in the 2020 International Pre-Conference papers demonstrates CIAE's commitment to being globally responsive and relevant. The word COVID appearing 88 times and COVID-19 appearing 86 times with mentions in two paper titles are an acknowledgement of the common threads of humanity and of hope for a surpassing future.

5. Sentence Openers in Academic Writing: A Comparison between Seminar Texts and Students' Reflective Writing Papers
- Author

Deveci, Tanju
- Abstract
Language used to report research findings and put forward arguments is at the heart of effective communication with readers. To this end, scholars use a variety of stylistic features. One of these is variety in language, which includes structures, lexis, and organization markers. Although much research has been conducted on these aspects, a particular feature has received limited interest from researchers: sentence openers, a strategic use of which helps authors develop an individual style, and avoid stagnant prose. This helps them maintain readers' interest while communicating scientific knowledge. Due to the importance of sentence openers in scientific prose, university students' awareness should be raised about this aspect of academic writing. This requires identification of commonly occurring sentence openers in the texts they study. It is also useful to identify student tendencies regarding sentence openers and their perceived competence in varying sentence openers. Prompted by these necessities, this research investigated a 10,949 running-word corpus compiled from professionally-written texts used in a first-year writing course, as well as a 42,070 running-word student corpus compiled from the reflective writing papers of 35 first-year students. Data on students' perceived competence were collected using a survey. Results showed that the two most frequent sentence openers in both corpora were subject-verb and transition markers. However, the latter were used by the students with significantly higher frequency than they were by the professional writers. Data also revealed that the students lack awareness of sentence openers as a feature for making writing more interesting. Students further reported an inability to use a wide range of sentence openers in their writing. Results are discussed, and recommendations are made for increasing students' skill in composing effective academic texts.

Saqr, Mohamm, Jovanovic, Jelena, Viberg, Olga, and Gaševic, Dragan
- Abstract
Predictors of student academic success do not always replicate well across different learning designs, subject areas, or educational institutions. This suggests that characteristics of a particular discipline and learning design have to be carefully considered when creating predictive models in order to scale up learning analytics. This study aimed to examine "if" and "to what extent" frequently used predictors of study success are portable across a "homogenous" set of courses. The research was conducted in an integrated blended problem-based curriculum with trace data (n = 2,385 students) from 50 different course offerings across four academic years. We applied the statistical method of single paper meta-analysis to combine correlations of several indicators with students' success. "Total activity" and the "forum" indicators exhibited the highest prediction intervals, where the former represented proxies of the overall engagement with online tasks, and the latter with online collaborative learning activities. Indicators of lecture reading (frequency of lecture view) showed statistically insignificant prediction intervals and, therefore, are less likely to be portable across course offerings. The findings show moderate amounts of variability both within iterations of the same course and across courses. The results suggest that the use of the meta-analytic statistical method for the examination of study success indicators across courses with similar learning design and subject area can offer valuable quantitative means for the identification of predictors that reasonably well replicate and consequently can be reliably portable in the future.

7. The Economic Impacts of Learning Losses. OECD Education Working Papers, No. 225

Organisation for Economic Cooperation and Development (OECD) (France), Hanushek, Eric A., and Woessmann, Ludger
- Abstract
The worldwide school closures in early 2020 led to losses in learning that will not easily be made up for even if schools quickly return to their prior performance levels. These losses will have lasting economic impacts both on the affected students and on each nation unless they are effectively remediated. While the precise learning losses are not yet known, existing research suggests that the students in grades 1-12 affected by the closures might expect some 3 percent lower income over their entire lifetimes. For nations, the lower long-term growth related to such losses might yield an average of 1.5 percent lower annual GDP for the remainder of the century. These economic losses would grow if schools are unable to re-start quickly. The economic losses will be more deeply felt by disadvantaged students. All indications are that students whose families are less able to support out-of-school learning will face larger learning losses than their more advantaged peers, which in turn will translate into deeper losses of lifetime earnings. The present value of the economic losses to nations reach huge proportions. Just returning schools to where they were in 2019 will not avoid such losses. Only making them better can. While a variety of approaches might be attempted, existing research indicates that close attention to the modified re-opening of schools offers strategies that could ameliorate the losses. Specifically, with the expected increase in video-based instruction, matching the skills of the teaching force to the new range of tasks and activities could quickly move schools to heightened performance. Additionally, because the prior disruptions are likely to increase the variations in learning levels within individual classrooms, pivoting to more individualised instruction could leave all students better off as schools resume. As schools move to re-establish their programmes even as the pandemic continues, it is natural to focus considerable attention on the mechanics and logistics of safe re-opening. But the long-term economic impacts also require serious attention, because the losses already suffered demand more than the best of currently considered re-opening approaches.

Adham, Raniah Samir and Lundqvist, Karsten Oster
- Abstract
Massive Open Online Courses (MOOCs) in the Arab World are still in their infancy. Many Arab countries are now starting to launch their MOOC platforms; however, there are only a few who have actually implemented such systems. This paper will explore online learning, in particular the rise of MOOCs around the world and their impact on the Arab World. The purpose of this paper is to give a true picture of the development of the first MOOC platforms in the Arab World. It will analyse in detail the concept, definitions, background, and types of MOOCs (xMOOCs and cMOOCs), as well as the main MOOCs platform in the Western and Arab worlds, and a timeline of the development of MOOCs. It will then observe the status of MOOCs in the developed world, opportunities in the Middle East, and the influence of Western MOOCs on the Arab world, from many perspectives, e.g. educational, religious, cultural and social.

- Abstract
Are teachers and principals aligned in their perceptions of the core components of the theory of Leadership for Learning across countries, or are there subgroups of schools in which there is misalignment? The purpose of this study is to examine the extent to which a congruency-typology model of leadership for learning is distributed across countries/economies using the TALIS 2018 dataset through examining the interaction of significantly different subgroups of teacher and principal responders through using multilevel latent class analysis (LCA) with a cross-level interaction. I analyse data from lower secondary schools of n=152 635 teachers in 9 079 schools and their principals across 47 countries/economies. Currently in the research literature on school leadership, leadership for learning has emerged as a framework to bring together managerial, transformational, distributed, and instructional leadership. Yet little is known about leadership for learning across national contexts. This study 1) maps the TALIS 2018 survey items to the current literature and surveys for leadership for learning, 2) then details the methods and analysis framework to examine if there are multiple significantly different types of teachers, principals, and schools from a leadership for learning theory framework. The final model 3) identifies a three-group teacher typology and a three-group principal typology, linking these types to school context, covariates, as well as teacher and principal training and experience. Results relate directly to the intersection of research, policy, and practice for training and capacity of school leaders across 47 countries/economies globally.

El Rahman, Sahar Abd and Zolait, Ali Hussein
- Abstract
This article describes how with the advent of computer-based technology, there is movement from manual to automated systems for different aspects of the education system. Testing is an essential part of teaching process that helps academics in classifying the level of students and evaluating the outcomes of their teaching process. The testing process requires a large amount of attention and professionalism. Automated Test Paper Generation is a system applying the shuffling algorithm in designing different sets of questions without repetition and duplication. It helps the faculty in developing and designing exams with a particular level of difficulty required in evaluating the students by using the utility-based agent. The system includes a knowledge base of many questions' types that are linked to a test engine where the faculty can specify the type and the difficulty level of the exam and then the system will assemble the exam and produce the output as electronic or paper-based. Questions will be picked randomly from the knowledge database. This automated system provides cost saving and time efficient solutions.

- Abstract
We study how large shocks impact individuals' skilling decisions using data from the largest online learning platform in Saudi Arabia. The onset of the COVID-19 pandemic brought about a massive increase in online skilling, and demand shifted towards courses that offered skills, such as telework, likely to be immediately valuable during the pandemic. Consistent with a model where individuals trade off reskilling costs with their expectations of future labor market conditions and their duration of work, we find that shifts into telework courses were largest for older workers. In contrast, younger workers increased enrollments in courses related to new skills, such as general, occupation-specific, and computer-related skills. Using national administrative employment data, we provide suggestive evidence that these investments in skills in early 2020 helped users maintain employment over the course of the pandemic.

15. The Influence of Assessor Training on Rater-as-Interlocutor Behaviour during a Computer-Resourced Oral Proficiency Interview-Cum-Discussion (OPI/D) Known as the 'Five Star Test.' Paper II.
- Author

Pollard, John D. E.
- Abstract
This paper considers the influence of the values and the discourse behaviors of the native-speaking assessor as interlocutor. These variables in the assessments of oral proficiency interrelate in complex ways with features of test design such as tasks, prompts, topics, guidelines, and assessor training. This paper reviews some previous studies, and looks at measures taken in the design of the "Five Star Test" to improve discourse and interactive consistency. An exploratory test suggests that assessor training might be a more beneficial area of attention for test developers than recent research indicates, especially when coupled with innovative features of test design. Previous research has shown that oral proficiency interviews could and should be made more like real conversations. This paper aims to take steps in that direction by incorporating innovative features into proficiency instrument design relating to aspects of test design, theme and topic, task design, and assessor/interlocutor training. It is concluded that, because the assessor "gaze" in signaling commitment and participation to the student being assessed has measurable effects on student performance in the second language, developmental investment in assessor training and awareness-raising would contribute to both test validity and reliability.

16. Interaction as a Construct of Oral Proficiency. Paper I.

Pollard, John D. E.
- Abstract
This paper describes efforts to devise a more effective method of assessing oral proficiency in English using a computer-based testing and computer-based test result management system. This new test would be designed to directly operationalize the second language constructs it measured, and would be developed with reference to the best practices revealed by recent research in the field. Scores are automatically sent to databases at the completion and evaluation of each task. Student performance is then used to drive an adaptive algorithm, determining the difficulty of successive tasks. This computerized testing would aid in assigning skills or constructs to individual tasks, apportion the skills required for each task, and identify the features of interaction elicited in individual tasks. The study results revealed not only which tasks elicited most assessor/interlocutor interaction, but also that a great deal of the interaction took place outside the task boundaries. There has been a substantial move towards acknowledging the importance of interaction in oral proficiency and, therefore, oral proficiency testing featuring discourse and conversation analysis. The research detailed in this paper indicates that greater interaction does seem to be associated with greater oral proficiency, yet there are nagging issues of test validity still to be addressed in future research.

Introduction: Scientometric analysis helps to measure the research growth and highlights the salient characteristics of the specific dataset. Saudi Arabia is rapidly growing country in the field of science and technology and remarkably contributing in the research productivity in all areas of health sciences, including radiological sciences from 1995 to 2000 and is drastically increased globally. Aim: To analyse the credible literature on radiological sciences research from Saudi Arabia as reflected in the Scopus database. Materials and Methods: This was a quantitative exploratory study based on scientometric analysis. The data was extracted from the Scopus database. The subject category of "radiology, nuclear medicine and imaging" was selected in the advanced search feature of the Scopus database. All the relevant scholarly literature consisted of articles and reviews indexed under the country name of Saudi Arabia published in English language from 1985 to 2020 were included for analysis. Results: Saudi Arabia was ranked 33rd with 1,587 papers in radiological sciences, representing 0.43% of the global share. The slow progress was observed in the first 20 years but the remarkable growth was recorded during the last five years of study. King Saud University and King Faisal Specialist Hospital and Research Centre were the most contributing institutions. Saudi radiologists collaborated with 99 countries of the world and the United States was on the top. Four national journals were included in the list of top 10 preferred journals. Conclusion: Although the rising tendency in radiological sciences research was evident during the last 10 years, still the share of Saudi Arabia was found much lower in comparison with the developed countries. Few well-established Institutions have taken lead in research productivity but a prioritised response from other Research Institutions is recommended. [ABSTRACT FROM AUTHOR]

One of the most widely used measures of scientific impact is the number of citations. However, due to its heavy-tailed distribution, citations are fundamentally difficult to predict but can be improved. This study was aimed at investigating the factors and parts influencing the citation number of a scientific paper in the otology field. Therefore, this work proposes a new solution that utilizes machine learning and natural language processing to process English text and provides a paper citation as the predicted results. Different algorithms are implemented in this solution, such as linear regression, boosted decision tree, decision forest, and neural networks. The application of neural network regression revealed that papers' abstracts have more influence on the citation numbers of otological articles. This new solution has been developed in visual programming using Microsoft Azure machine learning at the back end and Programming Without Coding Technology at the front end. We recommend using machine learning models to improve the abstracts of research articles to get more citations. [ABSTRACT FROM AUTHOR]

Scientometric studies play a crucial role in quantitatively assessing the impact and quantity of scholarly articles, providing a basis for policy-making and informed decision-making processes. Given the ongoing transformation within the Saudi scientific community across various domains, it is essential to establish a baseline for high-quality endodontic research. A comprehensive search in the PubMed database, using the keywords ["Saudi" OR "Saudi Arabia"] within the time frame of 2014 to 2021. The screening process involved evaluating the title and abstract of each article, with only those classified as endodontic articles included for analysis in this study. The analysis included factors such as the type of paper, the authors, the citations, and the year of publication. Featuring one or more authors affiliated with a Saudi dental institution, 70 papers were specifically categorized as endodontic papers. The most prevalent type of paper was case reports, accounting for 27 articles (28%), followed by literature reviews with 13 articles (18%). The number of authors ranged from one to ten, with a general trend of increasing publication rates over the years. In terms of citations, only four papers received more than 20 citations, while the majority of papers garnered between one and ten citations. Most articles in the field of endodontics exhibited low-level evidence. Therefore, it is recommended that the quality of research output and evidence be enhanced. [ABSTRACT FROM AUTHOR]

- Abstract
Fomites are inanimate objects that are capable of absorbing, harboring and transmitting infectious microorganisms. Paper currency, an exchangeable fomite, is constantly subjected to contamination. This study investigated bacterial contamination on the Saudi one Riyal paper note. Two hundred one Riyal bills (100 4th version and 100 5th version) were collected in the city of Jeddah for examination. The notes were examined for bacterial contamination using blood agar and MacConkey agar. Eighty-eight percent of the notes were contaminated with mixed (>or=2 types) bacterial growth. All 4th version notes had mixed bacterial growth: gram-positive bacilli (79%), coagulase-negative staphylococci (75%), Staphylococcus aureus (38%), Klebsiella spp (21%), Pseudomonas spp (19%), Escherichia coli (9%), viridans group streptococci (VGS) (8%), and non-hemolytic streptococci (4%). Seventy-six percent of the newer 5th version notes had mixed bacterial growth: gram-positive bacilli (68%), coagulase-negative staphylococci (64%), S. aureus (13%), Klebsiella spp (9%), Pseudomonas spp (5%), E. coli (2%) and VGS (2%). These results indicate the Saudi one Riyal paper note is commonly contaminated with bacteria, and may act as a vehicle for the transmission of potentially pathogenic bacteria. The more the bill had been handled the greater the contamination was.

- Abstract
This study aimed to analyze English as a Foreign Language (EFL) students' knowledge and perceptions of research method courses in the Department of English Language and Literature, at Imam Mohammad Ibn Saud Islamic University (IMSIU). It also investigated the problems that students encounter and offered some suggestions for improving these courses. The significance of the study is that such topic has never been investigated before in such context. The study participants were 1,022 students (Levels three, four, five, six and seven) who voluntarily filled out a questionnaire consisting of sections on four factors/themes: knowledge, perceptions, problems, and suggestions. The collected data were analyzed using IBM SPSS Statistics software to compare the students' answers, and a one-way analysis of variance test was used to detect the differences between academic levels regarding each theme. The results showed that regardless of the students' academic levels, all of them agreed on studying and therefore knowing the research basic components; however, regarding the elements constituting each of these basic components, significant differences were found between the five groups. The results also indicated that these students have positive perceptions of the courses even though they encountered some research-related problems such as in knowing all or some research basic components and their specific elements; writing all or some of them; citing, summarizing, and paraphrasing sources; allocating primary and secondary resources; collecting and analyzing data; and consulting research manuals. Finally, all students agreed that it would be helpful if they were assigned individual research supervisors and coauthored an article with them, a research course was taught in all academic levels for a bachelor's degree, a research club was established, and research seminars were held.

- Abstract
Objective: Oral cancer and precancers are a major public health challenge in developing countries. Researchers in Saudi Arabia have constantly been directing their efforts on oral cancer research and have their results published. Systematic analysis of such papers is the need of the hour as it will not only acknowledge the current status but will also help in framing future policies on oral cancer research in Saudi Arabia., Method: The search string "oral cancer" OR "Oral Squamous Cell Carcinoma" OR "oral premalignant lesion" OR "oral precancer" OR "Oral Potentially malignant disorder" AND AFFIL (Saudi AND Arabia ) was used for retrieval of articles from Scopus database. Various tools available in Scopus database were used for analyzing the bibliometric related parameters., Results: The search revealed a total of 663 publications based on the above query. Maximum affiliations were from King Saud University (163) followed by Jazan University (109) and then King Abdulaziz University (106). A large number of international collaborations were observed, the maximum with India (176) and the USA (127). The maximum number of articles were published in the Asia Pacific Journal of Cancer Prevention (34) followed by the Journal of Contemporary Dental Practice (33) and Journal of Oral Pathology and Medicine (19)., Conclusion: Saudi researchers are directing their efforts towards the public health menace of oral cancer. However, it was also observed that some institutions have emerged as front runners in research, whereas others are contributing significantly less. The health department should encourage and take necessary steps to increase the involvement of other institutions.

Designing standardized exams for EFL undergraduates is a matter of great concern in pedagogical practices that assess learners' academic achievements. This case study was conducted at Majmaah University, Saudi Arabia, to explore the significance of educational exam standardization and its impact on the process of implementation, leading to a balanced and equitable assessment of English language skills. During the study, 250 final English skill exam questions of two semesters were analyzed. A mixed-method approach using a questionnaire and Focused Group Discussion was adopted to collect relevant data. The quantitative data were analyzed using SPSS 16, and the qualitative data was processed by thematic analysis. The quantitative data results showed that questions were balanced, valid, and reliable in language skill exam papers designed for undergraduate English students. The qualitative data revealed four major themes -- standardization of questions, the efficacy of Bloom's taxonomy, assessment/evaluation, and alignment of the question with learning outcomes. These emerging themes highlighted the effectivness of standardizing exam papers, identified problems, and suggested ways of improvement. The study indicates that exams must be scrutinized for the sake of standardization in terms of maximum course coverage; the variety in the question item; clear, concise, and precise instructions; validity and reliability of exam papers; and the alignment of questions with the course and program learning outcomes to ensure the implementation of the revised Bloom's taxonomy. The study suggests, to generalize the results, that further investigation should be done in another Saudi university for the sake of comparison. [ABSTRACT FROM AUTHOR]

Desert cities are special type of places that need extra environmental care and additional health planning during the process of growth and development. Special considerations and regards ought to be paid to health-related projects like building hospitals, primary health care (PHC) centers, emergency services, sanitation facilities, etc. In a country like Saudi Arabia, where deserts form a large part of the available biome, selecting which cities and places to focus on during health-related project development can be a difficult process, lacking proper ways of classifying and comparing the general health status of the population. While there are established indices to calculate other health-related qualities, like the Air Quality Health Index, there is no general health quality index. The article presented herein advocates an appropriate formula for a health quality index, HQI, as a tool for quantifying health quality for any given desert community. HQI is intended to offer a unique number, which expresses overall health quality at a certain desert locality, at a specified period of time, which is based on several quality parameters and health indicators. The objective of HQI is to turn complex health quality data into flat, simple information that is understandable and usable by health authorities, the public and desert community members. HQI depicts the composite influence of different public health quality parameters and communicates health quality information to the general public and legislative decision makers. It is intended to represent a reliable picture of the overall health quality within a particular community. [ABSTRACT FROM AUTHOR]

GENDER differences (Sociology) ,ACADEMIC discourse ,MALE friendship ,MALE authors - Abstract
This study examines linguistic differences between male and female academic writing in Saudi Arabia, focusing on published research papers. Using Biber's multidimensional analysis as a model, the study examines both male and female authors' inherent lexical and grammatical preferences. A dataset of 20 research papers from each gender was tagged to analyze the linguistic features. ANOVA analyses were then conducted to identify patterns and variations. The research study provides interesting perspectives on the complex relationship between language and gender in academic settings. Though there are some similarities in the use of lexico-grammatical features between male and female research papers, noticeable differences suggest that gendered perspectives have an impact on scholarly writing. Both male and female research papers fall on the same polarity of the continuum across all five dimensions but with varying degrees. The findings suggest that male research writers tend to use more informational, explicit, and non-argumentative language while using less non-narrative and abstract discourse than their female counterparts. This study emphasizes how gender impacts the linguistic choices. [ABSTRACT FROM AUTHOR]

DIGITAL transformation ,FINANCIAL technology ,ISLAMIC finance ,BUDGET - Abstract
This paper aimed at a systematic review of the role of FinTech in enhancing the digital transformation of Saudi Arabian banks. Google Scholar was searched with related search terms to finally select 28 papers using the PRISMA process of screening and selection. There were very few papers directly dealing with the use of FinTech as a tool for digital transformation in banks, not specifically in traditional banks. There were a few papers on digital tools used in FinTech. Overall, the digital transformation of any kind of bank using FinTech tools had been slow and a small percentage of the total. The situation was worse in the case of Saudi banks despite the large amounts of budgetary allocations for technologies in banking as a part of its Vision 2030. This was because of the late entry of Saudi Arabia into these concepts. The need for Islamic banks to follow Sharia rules was not found to be a great problem. All these points indicate to the need for greater acceleration of using FinTech tools for the digital transformation of Saudi traditional banks. Some limitations of this review are the low rigour of the available papers due to methodological limitations, discussion papers without empirical data dominating and a wide range of aims provided in the papers. The need for substantially more work on Saudi banks has been highlighted. The validity of the conclusions from this review needs to be verified using empirical research. [ABSTRACT FROM AUTHOR]

Organization, individuals, and families in Saudi Arabia need more attention on recycling in their daily waste. The average generated daily rate of municipal solid waste is 1.72 kg per capita and the yearly kingdom waste recycling is around 15 million tons. Saudi government set a goal to reach 30million tons per year by 2033. This study examines the awareness level of paper recycling for university students in Saudi Arabia. A survey model consists of 26 measures that concentrated in attitudes, actions, and beliefs, is used. Seventy students in college of engineering at University of Jeddah responded to the survey. Moreover, barriers of adopting recycling paper in Saudi Arabia is analyzed and prioritized using Interpretive Structure Modeling (ISM) software. The findings indicates that the current state level of paper recycling awareness in Saudi Arabia is considered low, the education system does not support this issue, and there is a strong agreement that recycling for individuals and families in Saudi is not easy due to the absence of facilities such as containers and poor infrastructure. Furthermore, it indicates that the barrier "lack of laws that support recycling paper" is considered as the most critical barrier and it influences the rest of barriers. [ABSTRACT FROM AUTHOR]

- Abstract
Researchers have been interested in studying the correlates and reciprocity of peer acceptance across various cultures. Tenth grade students in a Saudi Arabian suburban high school completed social desirability scales to examine the relationship between the acceptance of class members by individual students and the acceptance of individual students by class members. Results showed that on the whole, relationships between individual students and the rest of the class were not universally reciprocal. This finding might have occurred because of lack of opportunities for student interaction in and outside school. Reciprocity of peer desirability which developed as a result of social interaction was not of the same type among students who expressed identical feelings towards one another. The results suggest that Saudi students, while skilled at initiating relationships, may have difficulty maintaining them. (JAC)

- Abstract
Despite considerable progress by Middle Eastern and North African countries in improving opportunities for women to access and attain education at all levels, much remains to be done. This report focuses on three sets of highly inter-related determinants of access, achievement, and outcome--macro-level societal determinants, school characteristics, and family background characteristics--in seven representative Middle Eastern and North African countries: Egypt, Tunisia, Morocco, Jordan, Turkey, Saudi Arabia, and Kuwait. The research shows that the level of economic development of a country and the distribution of income have a much stronger impact than do Islamic and cultural values, while the size and growth rate of the population can place a major strain on school facility and resources. Sex-role stereotypes and the division of labor in the home and marketplace mean that expected returns from female education do not appear to justify the costs. Free, compulsory education and open admissions have led to major improvements in female education but have no guaranteed equity. Socio-economic background, parental education, family size, and family socialization exert a strong influence on educational attainment. Other key factors are a family's ability to cover the costs of education and forego the labor of the daughters. The availability and accessibility of schools and the quality of their programs and human resources have significant effects on female educational enrollment, continuation, quality, and outcome. All-girls schools have played a positive role under certain conditions. Because of the importance of female teachers and administrators as potential role models, their high rate of attrition and absenteeism calls for careful solutions. Contains 104 references. (Author)

DATE palm , *WHEAT straw , *SODA pulping process , *PAPERMAKING , *AGRICULTURAL wastes - Abstract
The objective of this study was to characterize the properties of pulp and paper manufactured from two agricultural residues namely, wheat straw ( Triticum aestivum L. em Thell.) and date palm midribs ( Phoenix dactylifera L.) widely available in Saudi Arabia by employing soda-anthraquinone (AQ) pulping process. Specimens from cedar wood ( Juniperus procera Hochst. ex Endl.) wood was also used as control samples. Chemical and the morphological characteristics of all three types of raw materials in addition to basic properties of hand sheets made from such resources were evaluated. The results indicated that wheat straw had the highest hemicellulose and ash values of 35% and 7% and the lowest lignin content value of 18%, respectively. The fibre length of the both palm fronds and wheat straw was lower than that of 2.2 mm which was found for J . procera . Overall strength properties of the handsheet made from two agricultural raw materials were significantly lower than those made from J . procera pulp. Wheat straw handsheets also had higher strength properties than those made from date palm midribs with an exception of their tear index. Based on the results of this study it appears that both types of raw materials, date palm midribs and wheat straw could have a potential to manufacture pulp and paper with accepted properties so that such underutilized species can be converted into value-added products.

Aim: To perform a comprehensive bibliometric analysis encompassing all articles published on periodontics from Saudi Arabia. Materials and Methods: Using the Scopus database on June 8, 2023, the search term "PeriodonticFNx01" was entered in the primary search bar to extract all documents published on periodontics. Following, the year filter was applied to include articles published from the earliest available date until the date of data collection, excluding 2023. Next, we used the country/region filter to limit our documents to Saudi Arabia (n = 1929). We used Microsoft Excel (v.16) to examine periodical growth, collaboration patterns, influential institutions, frequently used sources, international research collaboration, and most-cited papers. Results: Saudi Arabia ranked 11th in periodontics research, contributing 3.43% to the global research output, reaching a peak of 7.63% in 2022. Notably, there was significant growth observed during the last 5 years of the study, with an average of 232.8 documents per year. The analysis of citations revealed that the selected documents received an average of 13.39 citations per document. Indigenous literature received less citation on average compared to internationally collaborated documents. King Saud University ranked first among the most productive institutions in Saudi Arabia, accounting 40.74% of the total output. The Journal of Contemporary Dental Practice published the highest number of documents, followed by the Saudi Dental Journal and the Journal of Periodontology. In terms of citation impact, the Journal of Periodontology emerged as the most influential, with an average of 32.83 citations per document. Research collaboration was most prevalent with researchers from the United States (22.03%), although Germany ranked first in terms of citation impact. Conclusion: Saudi Arabia's contribution to periodontics research has shown significant growth in recent years. The collaborative efforts with international researchers, particularly those from the United States, have played a crucial role in fostering advancements within the field. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to report the current status of life cycle assessment (LCA) in Saudi Arabia. It summarizes the LCA studies conducted in academia and industry. It also examines LCA collaboration networks and training opportunities. It then points out current gaps in implementing LCA in Saudi Arabia. Finally, it delineates the steps required to promote LCA both as a research methodology and as a sustainability assessment tool in Saudi Arabia. Methods: Using Scopus database and the Internet, a state-of-the-art review was conducted for this paper. "LCA", "Life Cycle Assessment" and "Saudi Arabia" were the key words used for searching scientific studies, industrial reports, training courses and conferences related to application of LCA within Saudi Arabia. The search resulted in 32 scientific documents and one industrial report. Further scrutiny reduced the final sample considered for this paper to eleven scientific documents and one industrial report that used a complete LCA study to report environmental impacts. Results and discussion: Studies considered for this paper were related to fossil fuels, buildings, electricity generation, desalination, and food consumption. However, overall number of publications and industry reports related to LCA in Saudi Arabia is very little as compared to other advanced economies. This sheer lack of studies conducted in Saudi Arabia can be attributed to lack of educational programs, consultancies, and research projects related to LCA. This points to the vast potential for developing LCA both as a research tool and sustainability assessment tool in Saudi Arabia. There is a need to develop a local network of LCA researchers, a local LCI database, and training courses. Conclusions: This study revealed that use of LCA as a sustainability assessment tool is still in its early stages within Saudi Arabia. There are only a handful of LCA studies that are reported in scientific literature related to Saudi Arabia. Additionally, most of these studies relies on non-local databases rendering the results of these studies less reliable. There is an urgent need to promote LCA within Saudi Arabia and academia can play a leading role by offering short courses, training for industry, and participating in joint projects to conduct LCA studies. Furthermore, local LCA databases and consultancies should also be promoted. It is conjectured that in the future, the use of LCA will grow in Saudi Arabia as the county is targeting to become a net zero carbon economy by 2060. [ABSTRACT FROM AUTHOR]

Almuhammadi, Anas
- Abstract
This study details the procedure and results of developing a mission statement at a language institute for the purpose of obtaining a program accreditation from an international language commission. A serious self-study process results in the development of a solid, true and ambitious mission since the mission covers all areas related to achieving students learning outcomes. It shows how the mission was changed and why. It also details how the new mission resulted in the improving quality, especially in the areas of curriculum and professional development of faculty and staff. Other aspects, such as facilities and student affairs were modified to achieve the goals and objectives of the new mission. This essay reports the changes that were implemented during the process of mission statement development. These changes resulted in plans to improve the quality of the English language teaching at the English Language Academy (ELA) which offers an English language program to Foundation Year students whose success in the program is a college requirement at the University of Business and Technology (UBT) in the academic year of 2016-2017. The program also aims at improving the English language proficiency of students so that they can use it in their future professions considering that the university logo is "Education for Job Opportunities." The third main goal or aim is related to the use of English to assist students in personal and social life. Critical thinking surfaced as a main concern of those surveyed for needs assessment. The report concludes with recommending conducting thorough and genuine self-study process which certainly ends with quality improvement. The report uses data collected from five questionnaires completed by students, faculty, alumni and employers of UBT graduates. The purpose of the survey was to identify the needs of the students. Based on those needs, the learning outcomes are identified and accordingly, the new mission statement is developed.

- Abstract
King Saud University (KSU) launched the SharePoint Server in September 2007. A website was created for each faculty and all faculty had to upload their publications, conference presentations and course materials. Since SharePoint is also a Learning Management System (LMS) with tools such as forums, blogs, wikis, a calendar, announcements, RSS feed, surveys, the present study aims to find out the percentage of KSU faculty utilizing those SharePoint LMS tools and the factors affecting their utilization. It was found that the KSU faculty have utilized the SharePoint's course tool to upload their course materials, exams, students' projects, Internet websites related to their courses. However utilization of the SharePoint LMS tools such as wikis, forums or blogs for instructional purposes is almost lacking. No training is provided in the SharePoint LMS tool utilization as they are considered of secondary importance.

Background: Health policy and systems research (HPSR) can strengthen health systems and improve population health outcomes. In the Eastern Mediterranean Region (EMR), there is limited recognition of the importance of HPSR and funding remains the main challenge. This study seeks to: (1) assess the reporting of funding in HPSR papers published between 2010 and 2022 in the EMR, (2) examine the source of funding in the published HPSR papers in the EMR and (3) explore variables influencing funding sources, including any difference in funding sources for coronavirus disease 2019 (COVID-19)-related articles. Methods: We conducted a rapid scoping review of HPSR papers published between 2010 and 2022 (inclusively) in the EMR, addressing the following areas: reporting of funding in HPSR papers, source of funding in the published HPSR papers, authors' affiliations and country of focus. We followed the Joanna Briggs Institute (JBI) guidelines for conducting scoping reviews. We also conducted univariate and bivariate analyses for all variables at 0.05 significance level. Results: Of 10,797 articles screened, 3408 were included (of which 9.3% were COVID-19-related). More than half of the included articles originated from three EMR countries: Iran (n = 1018, 29.9%), the Kingdom of Saudi Arabia (n = 595, 17.5%) and Pakistan (n = 360, 10.6%). Approximately 30% of the included articles did not report any details on study funding. Among articles that reported funding (n = 1346, 39.5%), analysis of funding sources across all country income groups revealed that the most prominent source was national (55.4%), followed by international (41.7%) and lastly regional sources (3%). Among the national funding sources, universities accounted for 76.8%, while governments accounted for 14.9%. Further analysis of funding sources by country income group showed that, in low-income and lower-middle-income countries, all or the majority of funding came from international sources, while in high-income and upper-middle-income countries, national funding sources, mainly universities, were the primary sources of funding. The majority of funded articles' first authors were affiliated with academia/university, while a minority were affiliated with government, healthcare organizations or intergovernmental organizations. We identified the following characteristics to be significantly associated with the funding source: country income level, the focus of HPSR articles (within the EMR only, or extending beyond the EMR as part of international research consortia), and the first author's affiliation. Similar funding patterns were observed for COVID-19-related HPSR articles, with national funding sources (78.95%), mainly universities, comprising the main source of funding. In contrast, international funding sources decreased to 15.8%. Conclusion: This is the first study to address the reporting of funding and funding sources in published HPSR articles in the EMR. Approximately 30% of HPSR articles did not report on the funding source. Study findings revealed heavy reliance on universities and international funding sources with minimal role of national governments and regional entities in funding HPSR articles in the EMR. We provide implications for policy and practice to enhance the profile of HPSR in the region. [ABSTRACT FROM AUTHOR]

Sign language is an essential means of communication for individuals with hearing disabilities. However, there is a significant shortage of sign language interpreters in some languages, especially in Saudi Arabia. This shortage results in a large proportion of the hearing-impaired population being deprived of services, especially in public places. This paper aims to address this gap in accessibility by leveraging technology to develop systems capable of recognizing Arabic Sign Language (ArSL) using deep learning techniques. In this paper, we propose a hybrid model to capture the spatio-temporal aspects of sign language (i.e., letters and words). The hybrid model consists of a Convolutional Neural Network (CNN) classifier to extract spatial features from sign language data and a Long Short-Term Memory (LSTM) classifier to extract spatial and temporal characteristics to handle sequential data (i.e., hand movements). To demonstrate the feasibility of our proposed hybrid model, we created a dataset of 20 different words, resulting in 4000 images for ArSL: 10 static gesture words and 500 videos for 10 dynamic gesture words. Our proposed hybrid model demonstrates promising performance, with the CNN and LSTM classifiers achieving accuracy rates of 94.40% and 82.70%, respectively. These results indicate that our approach can significantly enhance communication accessibility for the hearing-impaired community in Saudi Arabia. Thus, this paper represents a major step toward promoting inclusivity and improving the quality of life for the hearing impaired. [ABSTRACT FROM AUTHOR]

The integration of the Internet and communication technologies has improved our lives in numerous ways. To date, the Internet of Things has evolved the healthcare industry from healthcare 1.0 to 4.0 which is known as the MIoT. In Healthcare 4.0, data is shared among multiple stakeholders through the use of cloud computing, fog computing, and telehealth. MIoT devices and technology's interconnected, heterogeneous nature raises new concerns about access to confidential patient data, which is often done without patients' or medical staff's knowledge. This is because security and privacy concerns for MIoT devices and technology are frequently ignored or undermined by relevant stakeholders. Medical IoT security and privacy are becoming increasingly important as a result of the increasing number of security breaches targeting the MIoT in healthcare. To impartially reveal the research scenario of Security of MIoT biblioshiny and VOS viewer software are used to conduct a quantitative assessment of research papers belonging to this field for the period 2012-2021 in the Web of Science (WoS) and Scopus databases. From the results, it is seen that for the past 10 years, the sum of articles on Security of MIoT has increased. This research domain covers 35 territories. MIoT, Security, Privacy, authentication, access control are the most often used keywords in this field of research in recent years. The research flashpoints in the field primarily emphasize research directions such as the, the security and privacy concerns related to MIoT sensor data and how to get rid of them. The top five nations considering research volume are the China, India, Saudi Arabia, USA, and Korea, but a lack of collaborative work amongst these countries is seen. Finally, the paper provides future research directions on security of MIoT, such as Privacy of patient information, Lightweight Protocols for MIoT Devices, Trust management, patient data sharing and insecure networks.

Endodontics is a subdivision of dentistry that deals with diseases and injury of the soft tissues inside the teeth. The current study aimed to investigate the bibliometric properties of endodontics publications contributed by Saudi Arabia from 2010 to 2022. The quantitative bibliometric research method was applied to the meta-data retrieved from the Web of Science on December 7, 2022. The word Endodonti* was written in the main search bar, and from the year's filter, selected starting year 2010 to the date of data collection. In the first phase, to access the global publication growth of endodontics, no country/region filter was used. After getting the summary of the global intellectual landscape, we selected Saudi Arabia from the country/region filter to analyze certain characteristics of endodontics documents. Periodical growth, accessibility modes, collaboration patterns, influential institutions, frequently used sources, international research collaboration, and most-cited documents were analyzed by using Microsoft Excel (v.16) and SPSS (v.20). The authors affiliated with Brazil contributed the highest number of documents and Saudi Arabia stood in the eighth rank in endodontics research. The growing tendency was observed in Saudi Arabia from 1.29% in 2010 to 7.60% in 2022 from a global perspective. The quality of nonopen-accessed documents was higher than open-accessed as per citation impact, similarly, the documents written on international collaboration got a higher ratio of citations compared with national collaboration. King Saud University was found the most prolific institution and the Journal of Endodontics was the most preferred source of publications. The maximum research collaboration at the international level was performed with the authors of the United States. Fifteen most-cited papers obtained 21.42% of the citations. The findings show that endodontics research in Saudi Arabia has increased significantly over the years. The research collaboration at the national level has increased, which shows that teams of national researchers in endodontics have been prepared and conducting valuable research in a national context.

Background: It is essential for practicing clinicians to have core knowledge of biostatistics. However, surveys indicated that clinicians' attitudes towards biostatistics are negative. Despite its importance, little is known about the knowledge of and attitudes towards statistics among trainees in family medicine, particularly in Saudi Arabia. The current investigation attempts to evaluate knowledge and attitudes held by family medicine trainees in Taif and explore their correlates. Materials and Methods: This was a descriptive, questionnaire-based, cross-sectional study of residents in family medicine training programme in Taif, Saudi Arabia. We used Poisson regression modelling to evaluate the effect of background factors on knowledge and attitudes towards biostatistics. Results: The study included 113 family medicine trainees at different levels of training. Only 36 (31.9%) of the participating trainees expressed positive attitudes towards biostatistics. On the other hand, 30 (26.5%) participating trainees were found to have good biostatistics knowledge, compared to 83 (73.5%) trainees whose knowledge level was found to be poor. Upon adjusting for all background factors simultaneously, only younger age, level R4 training, publishing one or three papers were found to be associated with poorer attitudes towards biostatistics. Older age was associated with worsening of attitudes (adjusted odds = 0.9900, P = 0.00924), and so also was being a senior R4 trainee (adjusted odds = 0.9045, P = 0.01301). Publishing one paper (compared to publishing over three papers) was associated with poorer attitudes towards biostatistics (adjusted odds = 0.8857, P = 0.03525). Also, having published three papers (compared to publishing over three papers) was still associated with worse attitudes towards biostatistics (adjusted odds = 0.8528, P = 0.01318). Conclusion: The main finding of our current study is the poor level of knowledge and overtly negative attitudes held by family medicine trainees in Taif towards biostatics. Knowledge was particularly poor about advanced statistical concepts such as survival analysis and linear regression modelling. However, poor levels of knowledge about biostatistics could be a function of poor research productivity among family medicine trainees. Age, seniority in training and involvement in research also impacted positively on attitudes towards biostatistics. Therefore, it is recommended that the training curriculum for family medicine trainees should first cover essential biostatistics in a creative and accessible way and secondly encourage engagement research and publication from an early stage of training.

- Abstract
PCR assay using designed primers was evaluated in detecting human malaria infection from whole blood and/or on Whatman filter-paper compared to conventional microscopy. Two DNA extraction methods were used for dried blood-spots; QIAamp mini kit and methanol-fixation/heat-extraction. A total of 118 cases were collected from 4 hospitals at Jazan district. Microscopic examination showed positivity in 66/118 samples (56%). Thin films showed parasitaemia from 1+ to 4+. In PCR assay, 79 samples (70%) were positive for the genus Plasmodium given 153 base pair PCR product. All microscopy positive samples were PCR positive but PCR detected 13 cases missed by microscopy. As for filter-paper spot samples, 68 samples (57.6%) were PCR positive when DNA was extracted by QIAamp mini kit whereas 49 (41.5%) by methanol-fixation/heat-extracion method. PCR sensitivity decreased by using DNA extracted from filter-paper compared to microscopy and whole blood PCR. But the DNA isolated from filter paper detected parasites in many microscopy negative samples.
