This paper examines the history of glass colouring. It reviews Kitāb al-Durra al-maknūna of Jābir ibn Ḥayyān, which deals with the subject. The manuscript of this practical treatise was discovered recently. Part one of the paper deals with Jābir as a philosopher and chemist. The art of lustre-painting on glass originated in Syria during the Umayyad Caliphate in the eighth century and was soon practised in the neighbouring area. The paper reviews Arabic literature that deals with the colouring of glass (...) until the 13th century, and with pre-Islamic and Latin books of recipes that deal with glass colouring. Recipes for cast coloured glass are very few and scant in non-Arabic literature, and lustre-painting on glass was not mentioned in any treatise outside Arabic, even in the works of Theophilus and Neri. The colouring of glass gemstones by colour diffusion is not mentioned also. The paper compares the recipes of Kitāb al-Durra with the results of modern analysis of existing Islamic stained glass objects. There is a close correspondence, and the main indispensable ingredients in both cases are silver and copper compounds. Part one ends with an account of lāzaward as cobalt oxide in glass colouring. Part two of the paper gives a representative selection of recipes from Kitāb al-Durra for the three methods of glass colouring. (shrink)

The Liber de compositione alchemiae or the The Book of the Composition of Alchemy is believed to have been the first book on alchemy that was translated from Arabic into Latin. The translator was the Englishman Robert of Chester who was one of the earliest translators to flock to Spain to learn Arabic and to translate some of the Arabic works. He completed his translation on 11 February, 1144.

In 1908, public figures of the Egyptian civil society created the Egyptia University on the pattern of European universities. Foreign scholars belonged to its faculty including orientalists. The only Spaniard appointed as professor was Vicente Galarza y Pérez Castañeda, who taught philosophy in the years between 1915 and 1919. The article analyses the texts of his courses, taught in Arabic, and considers Galarza to be the first to apply the critical method in his university teaching.

The Arabic-Islamic tradition is founded on the following new epistemic attitude that reinvents knowledge: to learn from the contributions of previous civilisations through the systematic survey of all extant scientific works; to contribute to the further development of knowledge by linking it, through usefulness, to practice and the practical need of society; to facilitate its learning for younger generations and its transmission to future civilizations since it is conceived not as a finished product but as an ongoing process. The worldwide (...) development of the reinvented knowledge has led to its universalisation and the rapid expansion of mathematics has particularly and led to the complete de-hellinisation of the Greek conception of science and philosophy.

Este artículo trata de la actitud de la ley islámica acerca del transporte marítimo de las mujeres y de cómo las autoridades jurídicas musulmanas consideraban su presencia en los barcos. Discute las condiciones bajo las cuales las mujeres eran acomodadas y tratadas en los barcos así como el comportamiento personal y social que se esperaba de ellas. Con el fin de aplicar la ética islámica y las normas marítimas, los juristas informaban a los armadores, tripulaciones y pasajeros de cómo actuar (...) en el caso de comportamiento inmoral por alguna o varias de las partes. El trabajo se centra en el Mediterráneo Islámico, pero trata brevemente el castigo de la conducta social ofensiva en la Malasia islámica del siglo XIII. Por último, considera también la posición legal islámica sobre el transporte de musulmanes en barcos cristianos. (shrink)

This article deals with varieties of epistemological methods in calculating days of lunar calendar, mainly on the beginning date of months. Examining different methods in Indonesian Islamic-scape, it argues that there are three epistemological models which are rooted at Islamic classical epistemologies; the ahl al-hadith, the ahl al-ra‎y, and the intuitive sufi. The ahl al-hadith emphasizes on the empirical rukyatul-hilal, whereas the ahl al-ra’y strongly concerns on the mathematically rational method. The sufi, not so popular in Indonesia but influential in (...) some sufi circles, deploys the intuitive kashf method. In some cases, these three are however intertwined and in contradiction one to another. The article futher argues that different method-in-use is strongly influenced the local spesificties of diverse Indonesian Muslim’s backgrounds, and groupings. (shrink)

One of the Spanish Muslim authors that could not be identified until now is Muḥammad b. Aḥmad b. Abī l-‛Āṣ al-Andalusī, to whom two short medical treatises are attributed. A study of the preserved manuscripts of both works, as well as the revision of some sources and recently published studies, will allow us to identify this author as the Granadan Morisco Muḥammad b. Abī l-‛Āṣī, a physician that in the first half of the 17th century left the Iberian Peninsula to (...) reside in Istanbul, and afterwards in Cairo, where his trace is lost in the year 1637. In this article, we will expose all the available biographical data about this person, and we will make a brief analysis of his two treatises. (shrink)

Este artículo examina la propaganda establecida por Aḥmad al-Manṣūr al-Ḏahabī tanto en su correspondencia, como a través del ceremonial de la corte y de los cronistas, apologistas oficiales del sultán, propaganda que sacraliza extraordinariamente su figura y que roza en todo momento la pretensión mahdista, unida a la pretensión califal. Esta propaganda se realiza en el contexto de rivalidad con los Otomanos y en torno a la conquista del Sudán, conquista profundamente contestada por los ulemas marroquíes. La conclusión del artículo (...) es que la sacralización del poder islámico es siempre efímera y coyuntural y sólo puede hacerse a través de la figura del mahdī, una figura rupturista y a la que generalmente recurren los rebeldes al poder establecido: el recurso a esta figura por parte de un sultán es necesaria en un momento en el que los ulemas no consideran legítimo un poder o unas acciones emprendidas por tal poder.

Abū Dāwūd al-Sijistānī was a prominent collector of prophetic hadith. He seems to have collected in Iraq, Mecca, and Syria A.H. 220-35, then Khurasan till the early 240s, then Iraq, Syria, and Egypt till around 250. He claimed to have collected 500,000 in all. He spent most of the years 250-70 in Tarsus, composing his famous Sunan, then the last five years of his life teaching near Basra. This article reviews Abū Dāwūd's known works, especially al-Sunan, which became one of (...) the Six Books. The Sunan was transmitted from him in slightly different versions by nine named traditionists. A little under 90 percent of it goes back to the Prophet. It is distinguished from other collections by its concentration on hadith that classify actions . Abū Dāwūd's express comments within the Sunan concern alternative versions, legal applications, and rijāl criticism. Because it seldom repeats hadith under multiple topics, it is probably the largest of the Six Books. It must be admitted that Abū Dāwūd was unusually careless at identifying men in asānīd. In his personal piety, Abū Dāwūd stood above all for modesty. His separate collection of hadith on renunciation, al-Zuhd, comprises mainly the sayings of Companions. In law, Abū Dāwūd was close to Aḥmad b. Ḥanbal . In theology, he adhered to the ninth-century ahl al-sunnah wa-l-jamā‘ah. He is also said to have admired and been admired by the proto-Sufi Sahl al-Tustarī. (shrink)

In this study, after a short introductory information on the etymology, origin, and transition of botanical knowledge in Medieval Islamic Civilisation, we made a comparison of illustrated botanical works in Maghreb and Masriq through two illustrated books. We studied on randomly selected illustrations from Kitab al- Hashaish at-Tibb li-Diskuridus al-Aynzarbi translated by Istefan ibn Basil & Hunayn ibn Ishaq from Dioscorides’ Materia Medica, and Kitab al-Adwiyat al-Mufradat of Abu Ja’far Ahmad al-Ghafiqi, the Andalusian physician, pharmacist, and herbalist. We made (...) comparisons on the illustrations of nine plants and one lichen, chosen from Codex Osler of al-Ghafiqi, and Codices Ayasofya of Istefan-Hunayn, with real photos of plants and lichen, via the methods used currently in the science-art of botanical illustration. With this «botanical illustrative method», we conclude that in the same century, the work of al-Ghafiqi has been copied in a more accurate way than that of Istefan-Hunayn translation. -/- تخصص هذه الدراسة - بعد تقديم معلومات تمهيدية موجزة عن علم أصل الكلمات، وأصول وتطور المعرفة النباتية في الحضارة الإسلامية في العصور الوسطى - للتحليل المقارن للمؤلفات في علم النبات المصور في المغرب والمشرق، من خلال كتابين مصورين. و لهذه الغاية، قمنا بتحليل سلسلة من الرسوم، إختيرت بشكل تلقائي، أُخذت من كتاب النباتات الطبية لصاحبه دِيُسوفُورِيدس، و من ترجمة ابن استيفان ابن باسل و حنين ابن إسحاق لدراسة المادة الطبية لديسوفوريدس، و من كتاب الأدوية البسيطة لأبو جعفر أحمد الغافقي، و هو طبيب و صيدلي و عشاب أندلسي. لقد أجرينا مقارنات لرسوم تسعة نباتات و أشنة وقع الإختيار عليها من كتاب أوسلر للغافقي و من كتب أياصوفيا لإستيفان و حنين، مع صور حقيقية لعينات من هذه الأنواع، باستخدام الطرق المطبقة في وقتنا الراهن في فن وعلم الرسوم النباتية. و بعد تطبيق هذا المنهج التصويري النباتي، نستطيع أن نخلص إلى أنه، و على الرغم من إنتاجها في نفس القرن، فإن نسخ رسوم الغافقي النباتية كانت أكثر دقة من تلك الموجودة في ترجمة استيفان - حنين. الكلمات المفتاحية دِيُسوفُورِيدس، الغافقي، تاريخ علم النبات، الأندلس -/- Este estudio –tras una breve información introductoria sobre etimología, orígenes y evolución del conocimiento botánico en la civilización islámica medieval– está dedicado a un análisis comparativo de los tratados botánicos ilustrados en el Magreb y en el Máshreq, a través de dos libros ilustrados.

For the safe and economical construction of embankment dams, the mechanical behaviour of the rockfill materials used in the dam’s shell must be analyzed. The characterization of rockfill materials with specified shear strength is difficult and expensive due to the presence of particles greater than 500 mm in diameter. This work investigates the feasibility of using an extreme gradient boosting computing paradigm to estimate the shear strength of rockfill materials. To train and validate the proposed XGBoost model, a total of (...) 165 databases obtained from the literature are chosen. The XGBoost model was compared against support vector machine, adaptive boosting, random forest, and K-nearest neighbor models described in the literature. XGBoost beats SVM, RF, AdaBoost, and KNN models in terms of performance evaluation metrics such as coefficient of determination, Nash–Sutcliffe coefficient, and error in the root mean square ratio to the standard deviation of the measured data. The results demonstrated that the XGBoost model has the highest prediction performance with, followed by the SVM model with, RF, the AdaBoost model with and the KNN model with. A sensitivity analysis has been conducted to ascertain the impact of each investigated input parameter. This study demonstrates that the established XGBoost model for estimating the shear strength of rockfill materials is reliable. (shrink)

BackgroundBurnout is a syndrome that results from stressors in the work environment that have not been successfully managed. The prevalence of burnout among schoolteachers was always controversial. COVID-19 pandemic added more stressors to teachers since they had to change their working styles in response to the pandemic lockdowns or curfews. In Saudi Arabia, the prevalence and determinants of burnout among school teachers were not measured by any other group during the COVID-19 pandemic stressors.MethodsA cross-sectional survey was conducted among 879 teachers (...) in the Jazan region, Saudi Arabia, using the Maslach Burnout Inventory, during April 2021. Multistage cluster random sampling was used.ResultsThe mean age of the participants was 41.4 years. Male teachers represented 52.6% of the participants while females represented 47.4%. Most teachers showed burnout symptoms. Consequences of burnout were observed, such as using psychotropic medications, absenteeism, lack of job satisfaction, and changing schools. Using the MBI scale, most teachers showed medium or high emotional exhaustion, low depersonalization, and low personal accomplishment.ConclusionMost teachers showed symptoms of burnout during the COVID-19 pandemic. Being an expert and ability to adapt to technology during the COVID-19 pandemic proved to effectively reduce burnout symptoms. Increasing incentives, early detection, and improving the work environment is recommended to diminish burnout consequences. (shrink)

This paper proposes to present a novel method of generating cryptographic dynamic substitution-boxes, which makes use of the combined effect of discrete hyperchaos mapping and algebraic group theory. Firstly, an improved 2D hyperchaotic map is proposed, which consists of better dynamical behaviour in terms of large Lyapunov exponents, excellent bifurcation, phase attractor, high entropy, and unpredictability. Secondly, a hyperchaotic key-dependent substitution-box generation process is designed, which is based on the bijectivity-preserving effect of multiplication with permutation matrix to obtain satisfactory configuration (...) of substitution-box matrix over the enormously large problem space of 256!. Lastly, the security strength of obtained S-box is further elevated through the action of proposed algebraic group structure. The standard set of performance parameters such as nonlinearity, strict avalanche criterion, bits independent criterion, differential uniformity, and linear approximation probability is quantified to assess the security and robustness of proposed S-box. The simulation and comparison results demonstrate the effectiveness of proposed method for the construction of cryptographically sound S-boxes. (shrink)

Acts of violence arising from hatred, racism, and bigotry have no place in a world of civility. The brutal attacks on Muslim worshippers at two mosques in Christchurch, New Zealand, leaving 51 dead and 49 injured, can never be justified. Through adopting Van Dijk's ideological square of 'Us. vs. Them' [3], the present study uncovers the impact statements of the attacks' survivors and victims' families, denouncing the severity of the event and expressing the shattering effects of the attacks on self, (...) society, and humanity at large. Over a period of three days, about 90 people delivered their statements in the High Court in Christchurch. The data were compiled through YouTube videos and news articles that reported the testimonies. The findings showed that the overall discursive strategy used in the impact statements is that of positive self-presentation and negative other-presentation. Such presentations are realized by focusing on the positive aspects of the ingroup members represented by the attacks' survivors, victims' families, and people of New Zealand on the one hand, and the negative characteristics of the out-group members represented by the terrorist, on the other. As the paper sends a strong message for accepting 'otherness' and rejecting antagonism, it is of significance to readers and researchers in inter-faith dialogue, human rights, equality, freedom, and justice.

The present study aims at explaining how the Relevance Theory could be a viable approach to weigh up the main functions of some concessive Pragmatic Operators in Jordanian Arabic at the production and interpretation levels. A sample of twenty-two speeches delivered by members of the Jordanian Parliament the 16th was randomly selected for scrutiny. Three POs detected in their speeches were analyzed at the token level in light of three elementary RT assumptions about discourse connectives in general, namely connectivity, the (...) conceptual-procedural distinction, and monosemy. The major finding of this study was that concessive POs, as a subset of contrastives, are used to optimize relevance: highlight certain dimensions and/or suppress others of the scenario to the background. However, the point of departure from possibly all previous treatments is that the speakers, as politicians, still used them more strategically because total ambiguity resolution should not be a viable alternative in social settings laden with politics.

Breaking bad news (BBN) to parents whose newborn has a major disease is an ethical dilemma. In Saudi Arabia, BBN about newborns is performed according to the parental preferences that have been reported from non-Arabic/non-Islamic countries. Saudi mothers' preferences about BBN have not yet been studied. Therefore, we aimed to elicit the preferences of Saudi mothers about BBN concerning newborns. We selected a convenience sample of 402 Saudi mothers, aged 18-50 years, who had no previous experience with BBN. We selected (...) them via a simple number-randomization scheme from the premises of a level III Saudi hospital between October of 2009 and January of 2011. We used a hypothetical situation (BBN about trisomy 21) to elicit their preferences about BBN concerning newborns via a structured verbal questionnaire composed of 12 multiple-choice questions. We expressed their preferences as percentages (95% confidence interval), and we used the Kendall's W test (W) to assess the degree of agreement in preferences. The Saudi mothers preferred that BBN be conducted with both parents together (64% [60-69]), albeit with weak levels of agreement (W = 0.29). They showed moderate agreement in their preferences that BBN should be conducted early (79% [75-83], W = 0.48), in detail (81% [77-85], W = 0.52), in person (88% [85-91], W = 0.58), and in a quiet setting (86% [83-90], W = 0.53). With extremely weak agreement, they preferred to have a known person present for support during BBN (56% [51-61], W = 0.01), to have close bodily contact with their babies (66% [61-70], W = 0.10), and to have no another patients present (64% [59-68], W = 0.08). They showed moderate levels of agreement in their desires to detail, in advance, their preferences about process of BBN by giving a reversible, written informed consent that could be utilized for guidance, if needed (80% [76-84], W = 0.36). In our experience, Saudi mothers' preferences about BBN concerning newborns are varied, suggesting that a "one-size-fits-all" approach is inappropriate. A reversible, written informed consent detailing their preferences about BBN that would be kept in their medical records and utilized for guidance, if needed, may be the best solution, given this level of diversity. These findings merit further study. (shrink)

Purpose The purpose of this study is to examine the respondents’ evaluation of the pervasiveness of fake news through various SM platforms in Kuwait. The authors also examined the respondents’ attitudes toward most fake news on SM. A total of 1,539 Kuwaitis were selected. Design/methodology/approach The questionnaire was the major tool for this study. The respondents, from whom demographic information was obtained, were asked about which SM platforms most frequently spread fake news, their attitudes toward the subjects most frequently involved (...) in spreading fake news, their degree of use of the six SM platforms and interest in various subjects, and the attitudes toward the negative nature of SM news. SPSS was used for the data analysis. Findings The results showed that WhatsApp was the most likely to be used to disseminate fake news; Twitter and Instagram ranked second. The younger subjects were affected more by text and voice clips than the older ones. Originality/value The study, hopefully, produces new knowledge on the subject of fake news in social media, especially in the Arab world, since there are few studies conducted in the region. The study showed that WhatsApp was the SM tool most likely to be responsible for disseminating fake news in Kuwait, which may shed light on the usage of this application to be a news tool, rather than merely an interpersonal communication medium.

Background and AimPsycho-oncology is a cross-disciplinary and collaborative sub-specialty of oncology that focuses on the psychological, behavioral, ethical, and social aspects of cancer in clinical settings. The aim of this bibliometric study was to analyze and characterize the research productivity and trends in psycho-oncology between 1980 and 2021.MethodologyIn May 2022, the Scopus® database was searched for psycho-oncology-related publications using predetermined search keywords with specific restrictions. Lotka’s law was applied to check the authors’ productivity, while Bradford’s law was used to assess (...) the core journals in this field. The data was analyzed for different bibliometric indicators in the Biblioshiny package, an RStudio tool for bibliometric analysis.ResultsThe initial search resulted in a total of 2,906 publications. Of which, 1,832 publications were included in the final analysis, published between 1980 and 2021. The analyzed publications were written by 7,363 authors from 74 countries and published in 490 journals. There has been a significant increase in psycho-oncology-related publications after 2010. The most productive year was 2021. The annual scientific growth rate was found to be 13.9%. The most relevant leading author in terms of publications was Luigi Grassi from the University of Ferrara, Italy. Lotka’s law found that the number of authors declined as the number of papers written increased. The core journals were Psycho-Oncology, Supportive Care in Cancer, and Journal of Psychosocial Oncology. The most frequently used author’s keywords other than searching keywords were cancer, oncology, quality of life, depression, and anxiety. Recent psycho-oncology-related topics included mental health, COVID-19 infection in humans, people, pandemic, and tumor. The University of Sydney was the top-ranked institution. The leading country in terms of publications, citations, corresponding author country, and international collaboration was the United States of America. The United States had the strongest collaboration with Australia and Canada.ConclusionThe research hotspots include mental health conditions and interventions in cancer patients. We identified international collaboration and research expenditure to be strongly associated with psycho-oncology research productivity. Researchers’ collaboration, which is visible among developed countries, should be extended to low-income countries in order to expand psycho-oncology-related research and understanding. (shrink)

Emotion-based sentimental analysis has recently received a lot of interest, with an emphasis on automated identification of user behavior, such as emotional expressions, based on online social media texts. However, the majority of the prior attempts are based on traditional procedures that are insufficient to provide promising outcomes. In this study, we categorize emotional sentiments by recognizing them in the text. For that purpose, we present a deep learning model, bidirectional long-term short-term memory, for emotion recognition that takes into account (...) five main emotions. We use our experimental assessments on the emotion dataset to accomplish the emotion categorization job. The datasets were evaluated and the findings revealed that, when compared to state-of-the-art methodologies, the proposed model can successfully categorize user emotions into several classifications. Finally, we assess the efficacy of our strategy using statistical analysis. This research’s findings help firms to apply best practices in the selection, management, and optimization of policies, services, and product information. (shrink)
