Drawing on the sociocultural approach, this study aims to explore EFL learners’ perceptions toward collaborative writing, and the role that learners’ emotions play as a factor influencing their collaboration and achievements in face to face and Blackboard Chatbox as applied in their EFL classes. A mixed-methods research approach was used with a sample of 58 male students enrolled in writing courses at three levels at the Department of English Language and Translation, Qassim University. Three instruments were used for data collection; (...) a 45-item closed-ended questionnaire, semi-structured interviews, and the learners’ overall performance. The findings shown that most learners have positive perceptions toward studying online through Blackboard, and Blackboard Chatbox. Furthermore, Blackboard Chatbox could provide necessary affordances to facilitate learners’ emotion, which could enhance their collaborative writing. However, no significant difference was observed between learners’ performance in the two models of instruction. Taken together, the results of the present study enhance current understanding of the role of learners’ emotions in collaborative writing with the use of technology. (shrink)

In this article, ethylene glycol + waterbased Maxwell nanofluid with radiation and Soret effects within two parallel plates has been investigated. The problem is formulated in the form of partial differential equations. The dimensionless governing equations for concentration, energy, and momentum are generalized by the fractional molecular diffusion, thermal flux, and shear stress defined by the Caputo–Fabrizio time fractional derivatives. The solutions of the problems are obtained via Laplace inversion numerical algorithm, namely, Stehfest’s. Nanoparticles of silver are suspended in a (...) mixture of EG + water to have a nanofluid. It is observed that the thermal conductivity of fluid is enhanced by increasing the values of time and volume fraction. The temperature and velocity of water-silver nanofluid are higher than those of ethylene glycol + water -silver nanofluid. The results are discussed at 2% of volume fraction. The results justified the thermo-physical characteristics of base fluids and nanoparticles shown in the tables. The effects of major physical parameters are illustrated graphically and discussed in detail. (shrink)

The Wiener index WI is one of the connectivity parameters used to know the biochemical and physicochemical properties of compounds depending upon their molecular structures. Intuitionistic fuzzy graphs IFG s are a convenient tool to represent the objects and relations between them with two types of information using truth membership degree and falsity membership degree. This research work presents the concept of WI under the structure IFG s, I F trees, and I F cycles. Some bounds on WI are investigated. (...) The relationship between WI and connectivity index CI is also studied. In the end of this study, an application of the WI in transport network flow is proposed. (shrink)

Let G = V G, E G be a molecular graph, where V G and E G are the sets of vertices and edges. A topological index of a molecular graph is a numerical quantity which helps to predict the chemical/physical properties of the molecules. The Wiener, Wiener polarity, and the terminal Wiener indices are the distance-based topological indices. In this paper, we described a linear time algorithm that computes the Wiener index for acyclic graphs and extended this algorithm for (...) unicyclic graphs. The same algorithms are modified to compute the terminal Wiener index and the Wiener polarity index. All these algorithms compute the indices in time O n. (shrink)

The mathematical model of physical problems interprets physical phenomena closely. This research work is focused on numerical solution of a nonlinear mathematical model of fractional Maxwell nanofluid with the finite difference element method. Addition of nanoparticles in base fluids such as water, sodium alginate, kerosene oil, and engine oil is observed, and velocity profile and heat transfer energy profile of solutions are investigated. The finite difference method involving the discretization of time and distance parameters is applied for numerical results by (...) using the Caputo time fractional operator. These results are plotted against different physical parameters under the effects of magnetic field. These results depicts that a slight decrease occurs for velocity for a high value of Reynolds number, while a small value of Re provides more dominant effects on velocity and temperature profile. It is observed that fractional parameters α and β show inverse behavior against u y, t and θ y, t. An increase in volumetric fraction of nanoparticles in base fluids decreases the temperature profile of fractional Maxwell nanofluids. Using mathematical software of MAPLE, codes are developed and executed to obtain these results. (shrink)

Cryptocurrency has revolutionized the economic system of the world. It provides a new and innovative means of exchange that has speedily invaded the financial market trends and changed the traditional cash world. However, consumers have low acceptability for blockchain-based cryptocurrency due to increasing online scams and the absence of a regulatory framework. There is also a misconception about its usage on many platforms, which has created a clear gap in the literature to address this issue. Therefore, the current study intends (...) to investigate the effect of technology awareness on the behavioral intention of crypto users through perceived factors. It also empirically examines the moderating role of government support on these indirect paths. The underlying framework is investigated by surveying 333 respondents from the Z generation. Results revealed that perceived factors mediate the relationship between technology awareness and behavioral intention. Furthermore, government support strengthens the indirect relationship of technology awareness on behavioral intention through technology acceptance determinants, such that the effect of technology awareness on behavioral intention through perceived factors is more assertive when government support is high. The findings will provide a new dimension to different financial bodies implementing monetary policy and highlight the need to adopt innovative digital technologies in Pakistan. (shrink)

Very little attention has been given to understanding the commitment to service quality and desirable outcomes in the hotel industry. This study investigates the impact of directive and participative leadership on the frontline commitment to service quality through the mediation of knowledge sharing. This will eventually help us to generate the employees' commitment to service quality desirable behavior. The survey was distributed to 37 hotels. A total of 235 frontline employees participated in the survey. The study findings show that directive (...) leadership has a negative relationship with CSQ. On the other hand, participative leadership positively influences CSQ. Notably, knowledge sharing mediates between directive leadership, participative leadership, and commitment to service quality. There were positive linkages between commitment to service quality and desirable outcomes, job performance, and organizational citizenship behavior and negative relation to turnover intention.

The correlation coefficient between two variables plays an important role in statistics. Also, the accuracy of relevance assessment depends on information from a set of discourses. The data collected from numerous statistical studies are full of exceptions. The Pythagorean fuzzy hypersoft set is a parameterized family that deals with the subattributes of the parameters and an appropriate extension of the Pythagorean fuzzy soft set. It is also the generalization of the intuitionistic fuzzy hypersoft set, which is used to accurately assess (...) insufficiency, anxiety, and uncertainties in decision-making. The PFHSS can accommodate more uncertainties compared to the IFHSS, and it is the most substantial methodology to describe fuzzy information in the decision-making process. The core objective of the this study is to develop the notion and features of the correlation coefficient and the weighted correlation coefficient for PFHSS and to introduce the aggregation operators such as Pythagorean fuzzy hypersoft weighted average and Pythagorean fuzzy hypersoft weighted geometric operators under the PFHSS scenario. A prioritization technique for order preference by similarity to the ideal solution under PFHSS based on correlation coefficients and weighted correlation coefficients is presented. Through the developed methodology, a technique for solving multiattribute group decision-making problem is planned. Also, the importance of the developed methodology and its application in indicating multipurpose antivirus mask throughout the COVID-19 pandemic period is presented. A brief comparative analysis is described with the advantages, effectiveness, and flexibility of numerous existing studies that demonstrate the effectiveness of the proposed method. (shrink)

During the Mamlūk period (648-923/1250-1517), some developments such as the support of the state dignitaries for scholarly activities, the interest of the ʿulamā to the Mamlūk geography and the establishment of many scientific institutions increased the interest in scholarly activities in society. In this period of intensive scholarly activities, women also started to increasingly take part in this field, and as a result, many female scholars were trained. The fact that women scholars were encountered among the teachers of the famous (...) scientists of the period is a clear proof of this situation. As a matter of fact, the teachers of Najm al-Dīn Ibn Fahd, one of the famous muḥaddiths and historians of the 9th (15th) century, set an obvious example for this. Sixty-seven of his four hundred ninety-seven teachers were women. Najm al-Dīn Ibn Fahd, a member of a prominent ʿulamā family of Mecca, traveled to different cities in the Mamlūk geography and took lessons from many teachers, men and women. What is more valuable for our subject is that he wrote a work called Mu’jam al-shuyūkh, which contains extremely important information about his teachers. This article tries to assess women's participation in scholarly activities and social positions in Mamlūk society, based on his female teachers. This work, made up of two parts, first deals with women’s opportunities to pursue academic studies and their subsequent contributions to science. The second part is about their position in social life which stemmed from the families they belonged to and from their marriages. In this article, in which sixty-seven female scholars of Najm al-Dīn Ibn Fahd are discussed, some important results have been reached. This look into his sixty-seven female teachers shows how widespread women’s relationships with scholarly circles were in Mamlūk society, and that especially girls of families with scholarly traditions were included in academic circles from a young age. These girls were able to get their initial education from close relatives and then they were able to connect to academic circles easily via family relationships, taking courses with many scholars including women. Women have been instrumental in the transfer of knowledge more so than its production. Their efforts both during their studies and as scholars were focused on ḥadīth transmission. It is difficult to pinpoint the exact reason why ḥadīth sciences were the focus, but one can say that the ubiquity of ḥadīth sessions and their ease of accessibility must have been a factor. It is seen that young girls who participated in these sessions were encouraged to study with older scholars, thereby acquiring a strong isnād chain and becoming a source of information in later years for the transmission of knowledge. However, it is hard to say that every woman who got some education took a role in knowledge transmission. One can even claim, based on Najm al-Dīn Ibn Fahd’s female teachers, that a lot of women in academic circles did not take a role in knowledge transmission as scholars, despite their potential. The fact that no official institutions are mentioned with regard to women’s acquisition and transfer of knowledge may be indicative of the importance of teacher-student relationships rather than institutions, or, it can be that women were more active outside of these official institutions. Also, the fact that most of Najm al-Dīn Ibn Fahd’s female teachers were all taught by several common teachers shows the liveliness of academic activity outside of official institutions. There is very little narration regarding the social lives of women who were engaged in scholarly activities. Among the most important reasons why this is so is the desire to put their scholarly competencies to the forefront. However, it is possible to get some information about their families and marriages for many of them. One can see that Najm al-Dīn Ibn Fahd’s female teachers generally married men who were also engaged in scholarship. The fact that women, especially those in the scholarly class, married from among their relatives must have been related to this. All of the married women except one have at least one child. While divorce is not too common, marrying again as a result of the death of a husband or as a result of divorce is not rare. (shrink)

Fas Ahvâl-i Şahsiyye Kanunu üzerinde 2004 yılında yapılan reformlarla birlikte Fas Aile Kanunu (Müdevveneh), İslam dünyasındaki en eşitlikçi kanunlardan biri olarak kabul edilmektedir. Söz konusu reformlar, Fas'ta onlarca yıldır devam eden uzun soluklu kamuoyu tartışmalarının bir ürünü olarak ortaya çıkmıştır. Ahmed el-Hamlîşî 1980'lerin başından itibaren bu tartışmalara aktif olarak katılmış ve Ahvâl-i Şahsiyye Kanunu'nun yoruma açık insan yapımı bir kanun olduğunu ve revizyonunun ictihad yoluyla yapılması gerektiğini savunmuştur. Kral 6. Muhammed tahta çıktıktan kısa bir süre sonra, 2001 yılında, Fas Ahvâl-i (...) Şahsiyye Kanunu'nda reform yapmak üzere Kraliyet Danışma Komisyonu'nu oluşturdu. Kral 6. Muhammed komisyonu, Şeriat'ın temel hedeflerini (makâsıdü'ş-Şeria) gözeterek ve aynı zamanda ictihad yoluyla zamanın ve toplumun ihtiyaçlarına cevap vererek Ahvâl-i Şahsiyye Kanunu’nda önemli değişiklikler yapmakla görevlendirdi. Bununla birlikte, komisyon üyelerini kamu yararını göz önünde bulundurmaya ve önerilen her türlü değişiklikte uzlaşma ve ılımlılık için çaba göstermeye teşvik etti. Komisyon üyeleri önerilen değişiklikler üzerinde yaklaşık iki buçuk yıl çalıştı ancak birçok konuda uzlaşmaya varamadı. Bu bağlamda, üyelerin komisyon içinde oluşan iki ana gruptan reformist ve gelenekçilerden birine, az ya da çok, meylettiği söylenebilir. Ahmed el-Hamlîşî, Kraliyet Danışma Komisyonu'nun üyelerinden biriydi. Komisyon üyeleri arasında reformist grubun değişiklik tekliflerini destekleyen ama aynı zamanda bunu gelenekçilerin benimsediği dili kullanarak yapan etkili ve önemli bir isim oldu. Nitekim, el-Hamlîşî İslam hukuku çerçevesi içinde kalan eleştirel ama ılımlı görüşleriyle aile hukukunun reformunu talep eden gruplar için bir referans noktası haline geldi. Bu çalışmada, Ahmed el-Hamlîşî’nin fıkhi temellendirme ve delillendirme açısından Fas 2004 aile hukuku reformlarının arkasındaki isim olduğu savunulmaktadır. Veri analizi yönteminin uygulandığı bu çalışmada, öncelikli olarak Hamlîşî'nin eserleri, çeşitli mecralardaki mülakatları ve konuşmaları kullanılmıştır. Hamlîşî’nin anlayışındaki farklılık ve benzerlikleri ortaya çıkarmak için literatüre başvurulmuş ve benzer görüşlerle karşılaştırmalar yapılmıştır. Fas Ahvâl-i Şahsiyye Kanunu’nun reformuna dair kısa bir arka plan açıklamasının ardından bu makale, Hamlîşî'nin metin ve bağlam arasındaki arabulucu rolünü, aile hukuku reformları tartışmasındaki yerini ve dolayısıyla Şeriat-devlet ilişkileri konusundaki duruşunu incelemektedir. Daha sonra, ictihad kapısının kapanması meselesi, müctehid olabilmenin şartları, müctehidin nitelikleri ve Kraliyet Danışma Komisyonu tarafından uygulandığı şekliyle kolektif ictihad türü (cemâʿî ictihad) hakkındaki görüşlerine atıfla Hamlîşî’nin ictihad anlayışına odaklanılmaktadır. Son olarak, Hamlîşî'nin akıl yürütme yöntemi ve ortaya koyduğu gerekçeler aile hukuku ile ilgili meseleler örnekliğinde gösterilmektedir. (shrink)

La tarda antichità fu un periodo di profondi cambiamenti che coinvolse l’Europa, il mediterraneo e il cosiddetto Vicino Oriente, dal IV-V al VII-VIII secolo. Questo paradigma è ormai ampiamente utilizzato negli studi islamici, dagli studi coranici, dove Angelika Neuwirth ha ampiamente scritto sul tema delle basi bibliche della rivelazione coranica come manifestazione dello scritturalismo tardo antico, agli studi storici relativi al Corano e all’Arabia preislamica, come nel libro di Aziz al-Azmeh _The Emergence of Islam in Late Antiquity_, che riprende il (...) filone di studi instaurato da Julius Wellhausen e Toufic Fahd. Sono pienamente d’accordo con la necessità di inserire l’Islam, la sua nascita e il suo sviluppo storico, religioso e filosofico nel contesto della tarda antichità, ma è necessario sottolineare quali temi hanno fatto dell’Islam una nuova religione rispetto al giudaismo e al cristianesimo. Questo è il tema del presente articolo che si articola nei seguenti momenti: 1) una breve rassegna critica della letteratura sulla tarda antichità; 2) il rapporto tra gli imperi – romano, bizantino e sasanide – della tarda antichità e il trionfo del monoteismo; 3) il concetto di _hanifiyya_. La conclusione è che il messaggio coranico trasmesso da Maometto ha diviso la storia in due parti: prima e dopo la venuta della _verità_. Late Antiquity describes a period of profound transformations that involved Europe, the Mediterranean world and the so-called Near East, from IV-V to VII-VIII centuries. This paradigm has now become widely used in Islamic studies, from Qurʾānic studies, where Angelika Neuwirth has extensively published in the past on the subject of the biblical underpinnings of the Qurʾānic revelation as a manifestation of late antique scripturalism, to historical studies related to the Qurʾān and pre-Islamic Arabia, as in Aziz al-Azmeh’s book _The Emergence of Islam in Late Antiquity_, which takes up the trend of scholarship established by Julius Wellhausen and Toufic Fahd. I completely agree with the need to put Islam and its historical, religious, philosophical birth and development in the context of the Late Antiquity, but what is at stake is to emphasize which themes made Islam a new religion with respect to Judaism and Christianity. This is the focus of the present paper which deals with: 1) a brief critical survey of the literature on Late Antiquity; 2) the relationship between the empires – Roman, Byzantine and Sasanid – of Late Antiquity and the triumph of monotheism; 3) the concept of _hanifiyya_. The conclusion is that the Qurʾānic message conveyed by Muhammad broke the history into two parts: before and after the coming of _truth_. (shrink)

This paper examines the role of the face as it is caught suspended in private contemplation in candid photography. It starts with a celebrated lineage of photography of anonymous faces that promise the revelation of a secret, absorbed self: Paul Strand's 1916 portrait of a blind street peddler, made with a special right-angled lens; Walker Evans's New York subway portraits, shot clandestinely from under his coat; Luc Delahaye's L’Autre, “stolen” from the Paris Metro in the 1990s; and Philip-Lorca diCorcia's Heads, (...) gigantic strobe-lit portraits on the streets of New York. The paper then turns to Australian photographer Cherine Fahd, whose work insistently alludes to the redemptive potential of this promise. This potential is interpreted in terms of Emmanuel Levinas's ethical responsibility to the other, Ariella Azoulay's “civil contract of photography” and Giorgio Agamben's eschatological understanding of photographic testimony.
