This work identifies the influence of chaos theory on fractional calculus by providing a theorem for the existence and stability of solution in fractional-order gyrostat model with the help of a fixed-point theorem. We modified an integer order gyrostat model consisting of three rotors into fractional order by attaching rotatory fuel-filled tank and provided an iterative scheme for our proposed model as a working rule of obtained analytical results. Moreover, this iterative scheme is injected into algorithms for a system of (...) integer order dynamical systems to observe Lyapunov exponents and a bifurcation diagram for our proposed fractional-order dynamical model. Furthermore, we obtained five equilibrium points, including four unstable spirals and one saddle node, using local dynamical analysis which acted as self-exciting attractors and a separatrix in a global domain.

With the development of wireless technology, two basic wireless network models that are commonly used, known as infrastructure and wireless ad hoc networks, have been developed. In the literature, it has been observed that channel contention is one of the main reasons for packet drop in WANETs. To handle this problem, this paper presents a routing protocol named CCBR. CCBR tries to determine a least contended path between the endpoints to increase packet delivery ratio and to reduce packet delay and (...) normalized routing overhead. Moreover, throughout the active data section, each intermediate node computes its channel contention value. If an intermediate node detects an increase in channel contention, it notifies the source node. Then the source node determines another least contended route for transmission. The advantages of CCBR are verified in our NS2-based performance study, and the results show that CCBR outperforms ad hoc on-demand distance vector in terms of packet delivery ratio, end-to-end delay, and routing overhead by 4% to 9%.

The Sufyānī narration, which is also referred in some studies carried out today, is mentioned in the early Shiite and Sunnī sources. The anticipated savior perception of the period has an important place in understanding the Sufyānī narrations in the emergence process of which political and sectarian events were effective. Narrations stating that the Mahdī named Muḥammad, one of the descendants of the Prophet Muḥammad (pbuh), would appear in the end of times and establish justice by bringing order to the (...) world where oppression, injustice and inequity have spread, were effective in the political and social life after the Prophet (pbuh). The emergence of the Sufyānī narrations, whose intellectual infrastructure was constituted by the expected Mahdī perception that is effective in the society, was the result of the political conflicts of the period. The death of Muʻāwiya ibn Yazīd (d. 64/684), the third Caliph of the Umayyad State, without leaving a crown behind caused a political crisis. The cousin of the Muʻāwiya II, Marwān bin al-Ḥakam, the experienced politician who turned this moment of crisis into an opportunity and who was from the same dynasty but from a different family, took over the administration and thus the sultanate continued. Although the reign continued from the sons of Umayyad, the administration passed from sons of Sufyān to the sons of Marwān, who were from the same dynasty. This situation caused discomfort in Sufyānīs. Thus, Muʻāwiya II's brother Khālid ibn Yazīd, whose right of administration was seized from him, with the intention of gaining his lost reputation in the society and turning the pessimism towards his family into hope and desire, has been claimed to spread the savior Sufyānī narrations expected from the sons of Sufyān, parallel to the Mahdī narrations expected from the sons of Alī, which was influential in the society. Thus, the Sufyānī came to be expected like the expected Mahdī, who was influential in society and exploited by the Shiite sects in their own belief systems. The rebellions carried out by the sons of Sufyān against the administration in the 2nd century hijrī and afterwards were conceived as the appearance of the Sufyānī expected by the society and the person who led the rebellion was described as Sufyānī. The most important of these rebellions is the revolt of ʻAlī ibn Abdullah ibn Khālid nicknamed Abū ʻAmayṭar, formed by the coalition of sons of ʻAlī and sons of Sufyān who descend from the sons of Umayya. Abū ʻAmayṭar, who is considered to be the Sufyānī and some sections of whose life constitute a source for many narrations on the Sufyānī, declared his caliphate during the period of Abbasī Caliph al-Amīn (d. 198/813) and called for allegiance to himself. The announcement of his caliphate was considered by his supporters as the expected savior. The period of Abū ʻAmayṭar and the sayings about him are extremely important in terms of presenting the expected savior perception in the society, the Sufyānī understanding and the date of his emergence. Sections from Abū ʻAmayṭar's life reflected in the narrations about the Sufyānī in many Shiite and Sunnī sources. In this article, it is tried to examine the emergence of the Sufyānī narrations, its development and particularly its transformation within the Shiite sect, in a detailed manner and especially based on political and sectarian events of the early period.

Qutayba ibn Muslim al-Bāhilī is one of the leading soldier-bureaucrats of the Umayyads period. During the time he served as the governor of Khurāsān, he consolidated the Umayyad’s rule in Tokharistan and Transoxiana provinces, and expanded the borders of the state to China by conquering the Kashgar region. His activities for conversion of the people of the conquered regions have great importance in the history of Islam since the intense relations of the Turkish people with Islam fell upon the time (...) of his governorship. It is possible to argue that by introducing the religion to these people Qutayba had played an important role in their conversion to Islam. It is also known that he had sent a delegation to the emperor of China for the same purpose. However, despite all his achievements, it is seen that the academic studies about Qutayba in our country are very rare. Besides, some of the recent studies about him claim that he was a fraud, a trickster, and an untrustworthy person in his military activities; and had committed mass murders and massacres, persecuted innocent people, destroyed and burned the cities of conquered lands. In this article, it is examined that whether these claims and accusations have their justifications or not by consulting the main sources. In fact, what is expected from constructive criticism in this subject and every other area is to clarify the matter and make it more comprehensible of its context. However, it should not be forgotten that some conclusions over Qutayba in these studies might have been drawn to quickly in order to manipulate the conquest movements of the Umayyad period.Summary: The religious interaction and change taken place in the Arabian Peninsula with the emergence of Islam and with the political, military and cultural activities of the Muslims performed during the periods of Prophet Muhammad and the Rāshidūn (rightly guided) Caliphs had significant effects upon the lands of Iraq, Syria, Egypt and Khurāsān where the ancient civilizations located.The success made by the Muslim-Arabs in such a short time is accepted of course as one of the important events of world history. The message of Islam spread rapidly with their extraordinary efforts, and reached quickly in the early days of Islam to the Amu Darya/Oxus River, which is considered to be the natural border between the Iranians and the Turks (Iran and Turan).Although the Turks who had been struggling to dominate the region for centuries gained an opportunity with the disappearance of the Sasanian Empire from history, they could not take advantage of this new situation because of their lack of political unity and a strong state, and the power held by the regional Turkish Sultans were not enough to make their dominance happen. In this conjuncture, the Muslim-Arabs who appeared in the stage of history in a relatively late period but had the ideal of being a regional and a global power had rapidly realised their political and military activities called “conquest” in the Islamic historical sources. When it comes to the period of Caliph ʿUthmān, it is seen that the conditions were very suitable for passing to the east of the Oxus River where the Turkish elements lived intensively. At the time, the absence of a strong Turkish state in the region, and China’s occupation with its own internal problems made an important contribution for the Muslim-Arab capture of the region. In this region, which is called as “Transoxiana” in the Arabic sources, it is seen that the Turks organized their political structures as city-states and regional sultanates. In the north-eastern parts of this region, there was a strong Turkish State called the Turgish State and it provided political and military support to the people of the region who rebelled occasionally the Umayyads.After solving the internal problems of the state largely and suppressing some dangerous revolts, the Umayyad Caliph ʿAbd al-Malik ibn Marwān became capable of initiating military activities beyond the borders of the state. Nevertheless, the period when the actual conquests were made was the period of his son Walīd (86/705-96/715). It is seen that the conquests made in his time were permanent, and the people who lived in the conquered lands accepted Islam to a large extent. The conquest made during Walīd’s time which extended from Kashgar to the Pyrenees, realised at an unprecedented pace. The most important name for the eastern side of the conquests is undoubtedly Al-Ḥajjāj ibn Yūsuf. Ḥajjāj (75/694-95/714) who acted as the supreme governor of Iraq for nearly twenty years, had achieved important successes in the regions of Transoxiana and Sindh located in the eastern part of the country by the hands of his appointed governors. However, many governors appointed by him to Khurāsān from 75/694 to 86/705 with the hope of reaching his goals in the east could not meet his expectations because of the political, social and economic problems that existed throughout the country, and because of the resulting rebellions in the regions that these problems caused.These unwanted conditions continued to be seen in the region until he appointed Qutayba ibn Muslim as the governor of Khurāsān (86 / 705-96 / 715) who was one of the young commanders and administrators educated by Ḥajjāj personally. Qutayba known as having a close relationship with Ḥajjāj and consulting him when taking important decisions acted in this direction throughout the time he stayed in this position.It is known that the internal conflicts in the region continued during the time when Qutayba was appointed as the governor of Khurāsān. However, he had brought together northern and southern Arabian tribes living in the region with religious, political and economical suggestions and had succeeded in persuading them for military activities that he decided to operate beyond the Oxus. For the Umayyads, these military operations were justified, because the regional sultans who ruled in the western and eastern sides of the Oxus repeatedly violated the agreements they had made before. The tendency of the people of Turkic, Iranian, and Tajik origin who were the real owner of these lands and lived in both sides of the rich Oxus basin for many centuries to violate these agreements was in fact result of a great concern. They now realized that the Muslim-Arabs who followed a systematic settlement policy in the region came to their lands this time without any intention of going back. Even though Qutayba followed a fair and reasonable policy towards them, they violated their agreements with him, formed alliances among themselves and waged military campaigns against Qutayba not to be the subjects of any change in their religion, worldview, and perception of existence.Qutayba, who is believed to have spent his its utmost efforts to make the religion of Islam and the Umayyad political cause permanent in the region under these unfavourable conditions, has been recently criticized by some researchers. The criticisms intensify around the claims that he persecuted people, committed massacres, and behaved unfaithfully by breaking his promises that he made with people. From the perspective of our own times, it is possible to think that sometimes he had taken extreme measures in punishing the sultans and the persons who raised armed struggles against him and caused riots by violating the agreements. However, when the period is compared with the others, it can be easily said that the Umayyads showed in these and other remote areas a considerable amount of tolerance that they had never shown it in their internal conflicts. It is a known fact that he generally clashed with the ones who disrupted agreements, sought help from external forces, established alliances against them, and refused to pay taxes. Based on historical sources, it does not seem to be possible to say that while doing these activities in the region, Qutabya did not behave entirely in a way that his behaviour could be classified as massacres committed against innocent civilians. On the contrary, it is known that Qutayba had given many chances to the people of the region in administrative and military affairs. As a matter of fact, he ruled the city of Bukhara for 20 years with a Turkish ruler whom he appointed and supported, and he included in his army a union of twenty thousand cosmopolitan soldiers assembled from the people of Bukhara, Baykend, Chach and Samarkand and paid a regular salary to them.The fact that his grave known as the “Imam Shaykh Qutayba Tomb” was turned later into a shrine and visited by the people even today despite the passage of long centuries after his death shows that he has been loved by the people of the region and that they have always considered him as a conqueror-bureaucrat who spent his life for the ideals of his religion.

Cardiac disease is the leading cause of death worldwide. Cardiovascular diseases can be prevented if an effective diagnostic is made at the initial stages. The ECG test is referred to as the diagnostic assistant tool for screening of cardiac disorder. The research purposes of a cardiac disorder detection system from 12-lead-based ECG Images. The healthcare institutes used various ECG equipment that present results in nonuniform formats of ECG images. The research study proposes a generalized methodology to process all formats of (...) ECG. Single Shoot Detection MobileNet v2-based Deep Neural Network architecture was used to detect cardiovascular disease detection. The study focused on detecting the four major cardiac abnormalities with 98% accuracy results were calculated. The work is relatively rare based on their dataset; a collection of 11,148 standard 12-lead-based ECG images used in this study were manually collected from health care institutes and annotated by the domain experts. The study achieved high accuracy results to differentiate and detect four major cardiac abnormalities. Several cardiologists manually verified the proposed system’s accuracy result and recommended that the proposed system can be used to screen for a cardiac disorder. (shrink)

Our aim here is to show that an enigmatic text of Avicenna's Glosses, devoted to the problem of evil, takes on its full meaning in the light of the last chapter of the Šifā ' on De generatione et corruptione. We will see how Avicenna, deepening and developing a cosmological argument already present in the commentary of Alexander of Aphrodisias on the De generatione, ends up building most of his theodicy on the relative incommensurability of the different celestial periods. All (...) the problem of divine Justice is thus reinterpreted in terms of opposition between discrete and continuous. Finally we will show the importance that this development of Avicenna had in Western Christendom in the 14th century, and the complex relationship which Leibniz has with it in his recently edited reflections on the Great Year.

Recruiting patients into clinical research is essential for the advancement of medical knowledge. However, when the physician undertaking the care of the patient is also responsible for recruitment into clinical research, a situation arises of an inter-role breach of confidentiality which is distinguishable from other conflicts of interest. Such discord arises as the physician utilizes confidential information obtained within the therapeutic relationship beyond its primary objective, and safeguards ought to be observed in order to avert this important, and generally overlooked, (...) problem. The moral worth of the pledge of confidentiality is based not on its innate value but on its being a promise on which subsequent interactions and disclosures are founded. Within the patient-doctor interaction, confidentiality is an important facet of the promised fidelity and, as such, a loose interpretation of the notion threatens the essence of the relationship, and any violation thereof requires compelling moral justification. To avoid conflict, patients' confidential information ought not be used for the purpose of recruitment, which needs to be undertaken through general education and non-directed appeals, and a preliminary consent to be approached for research should be obtained from the patient prior to her being identified as a suitable research subject. Securing this prior consent would avoid one source of potential, albeit unintended, coercion. (shrink)

The application of game elements of gamification in online shopping is attracting interest from researchers and practitioners. However, it remains unclear how gamification affects and improves consumer purchase intention on online shopping platforms, which still leaves a gap in our knowledge. To narrow this theoretical gap, a theoretical model has been built in this study. This model adopts cognitive evaluation theory to explain the impact of gamification elements on consumer purchase intention. Data was collected from 322 online shopping consumers who (...) used a flash game to test their purchase intention after playing games. The results show that game rewards, absorption and autonomy of gamification positively enhance sense of enjoyment, and that it helps people meet their psychological needs, which ultimately affects the online purchase intention of consumers. This study is helpful in analyzing the factors involved in the successful introduction of gamification on online shopping platforms in more detail. (shrink)

Impostor syndrome or Impostor phenomenon is a belief that a person thinks their success is due to luck or external factors, not their abilities. This psychological trait is present in certain groups like women. In this paper, we propose a neutrosophic trait measure to represent the psychological concept of the trait-anti trait using refined neutrosophic sets. This study analysed a group of 200 undergraduate students for impostor syndrome, perfectionism, introversion and self-esteem: after the COVID pandemic break in 2021. Data labelling (...) was carried out using these neutrosophic trait measures. Machine learning models like Support Vector Machine(SVM), K-nearest neighbour (K-NN), and random forest were used to model the data; SVM provided the best accuracy of 92.15%. (shrink)

This research article offers a study on a new relation of rough sets and soft sets with an algebraic structure quantale module by using soft reflexive and soft compatible relations. The lower approximation and upper approximation of subsets of quantale module are utilized by aftersets and foresets. As a sequel of this relation, different characterizations of rough soft substructures of quantale modules are obtained. To ensure the results, soft reflective and soft compatible relations are focused and these are interpreted by (...) aftersets and foresets. Furthermore, the algebraic relations between upper approximation of substructures of quantale module and the upper approximations of their homomorphic images with the help of quantale module homomorphism are examined. In comparison with the different type of approximations in different type of algebraic structures, it is concluded that this new study is much better. (shrink)

Recent studies from Western countries indicate significant levels of questionable research practices, but similar data from low and middle-income countries are limited. Our aims were to assess the prevalence of and attitudes regarding research misconduct among researchers in several universities in the Middle East and to identify factors that might account for our findings. We distributed an anonymous questionnaire to a convenience sample of investigators at several universities in Egypt, Lebanon, and Bahrain. Participants were asked to a) self-report their extent (...) of research misconducts, as well as their knowledge of colleagues engaging in similar research misconducts and b) provide their extent of agreement with certain attitudes about research misconduct. We used descriptive, bivariate, and multivariate logistic regression statistics to analyze the data. Data from 278 participants showed a high prevalence of misconduct, as 59.4% of our respondents self-reported to committing at least one misbehaviors and 74.5% reported having knowledge of any misbehaviors among any of their colleagues. The most common type of self-report misconduct was “circumventing research ethics regulations” followed by “fabrication and falsification”. A significant predictor of misconduct included a lack of “prior ethics training”. Scientific misconduct represents a significant issue in several universities in the Middle East. The demonstration that a lack of “prior ethics training” was a significant predictor of misconduct should lead to educational initiatives in research integrity. Further studies are needed to confirm whether our results can be generalized to other universities in the Middle East. (shrink)

The COVID-19 outbreak wreaked havoc on the hospitality business, resulting in significant layoffs, salary cuts, and unpaid leaves globally. This study uses the sensemaking theory to investigate how COVID-19 induced unfavorable human resource practices affect the link between perceived corporate social responsibility and employee identification and commitment. We tested this model using the data collected from 392 hospitality sector employees in Pakistan. The results reveal that “cut in salaries” and “work from home” positively moderate CSR’s impact on employees’ identification and (...) commitment. On the other hand, employee layoff and leave without pay do not impact the positive relationship between CSR and employees’ attitudes. Furthermore, the study finds that CSR during this pandemic has a significant positive impact on employees’ attitudes. However, this relationship becomes insignificant for employees who reported unfavorable HR practices in their organizations. The finding further reveals that CSR’s impact during COVID-19 on employees’ attitudes is moderated by the different levels of CSR importance in employees’ minds. This evidence is significant since HR practices implemented during this crisis need to be identified and framed to understand the effects of CSR on employee commitment and identification. CSR involvement in the pandemic can help managers keep their employees committed to organizations; only if this charity begins from their internal stakeholders first. (shrink)

Although the role of leadership in fostering employee creativity has been extensively studied, it is still unclear whether and how leader humor affects employee creativity. Drawing upon cultural representation theory, we examined creative self-efficacy as a mediator and traditionality as a situational factor in the relationship between leader humor and employee creativity by analyzing a sample of 306 employees and 88 leaders collected through survey questionnaire from firms based in Hubei Province, China, covering the industries of automobile, IT, and medicine. (...) Following the multi-level examination, leader humor was positively related to employee creativity, and creative self-efficacy was found to mediate the impact of leader humor on employee creativity. Furthermore, traditionality moderated the effect of leader humor on creative self-efficacy, as well as the indirect effect of leader humor on employee creativity through creative self-efficacy. This study provides a social psychological explanation for the association between humor and employee creativity, deepens the current understanding of the influence process of leader humor. Finally, the theoretical and practical implications of the study are discussed at the end alongside limitations and recommendations for future research. (shrink)

BackgroundConsenting for retrospective medical records-based research (MR) and leftover tissue-based research (TR) continues to be controversial. Our objective was to survey Saudis attending outpatient clinics at a tertiary care hospital on their personal preference and perceptions of norm and current practice in relation to consenting for MR and TR.MethodsWe surveyed 528 Saudis attending clinics at a tertiary care hospital in Saudi Arabia to explore their preferences and perceptions of norm and current practice. The respondents selected one of 7 options from (...) each of 6 questionnaires.ResultsRespondents' mean (SD) age was 33 (11) years, 42% were males, 56% were patients, 84% had ≥ secondary school education, and 10% had previously volunteered for research. Respectively, 40% and 49% perceived that the norm is to conduct MR and TR without consent and 38% and 37% with general or proposal-specific consent; the rest objected to such research. There was significant difference in the distribution of choices according to health status (patients vs. companions) for MR (adjusted Kruskal-Wallis test P = 0.03) but not to age group, gender, education level, or previous participation in research (unadjusted P = 0.02 - 0.59). The distributions of perceptions of current practice and norm were similar (unadjusted Marginal Homogeneity test P = 0.44 for MR and P = 0.89 for TR), whereas the distributions of preferences and perceptions of norm were different (adjusted P = 0.09 for MR and P = 0.02 for TR). The distributions of perceptions of norm, preferences, and perceptions of current practice for MR were significantly different from those of TR (adjusted P < 0.009 for all).ConclusionsWe conclude that: 1) there is a considerable diversity among Saudi views regarding consenting for retrospective research which may be related to health status, 2) the distribution of perceptions of norm was similar to the distribution of perceptions of current practice but different from that of preferences, and 3) MR and TR are perceived differently in regard to consenting.

This article aims to unravel the doctrine of the “sign from the manifest to the hidden” of Abū Hāšim al-Ğubbāʾī. It shows that Abū Hāšim tended to interpret this sign as an inference, of which he recognized two main types: Type-1 proceeds by analytical deduction of concepts by neutralizing the conditions of their realization, i. e. their ontological basis. This is, typically, the procedure most directly consonant with Abū Hāšim's modal ontology. Type-2 exhibits the same causal relationship at the known (...) and unknown levels and considers causality at the known level to be itself the cause of causality at the unknown level. This partition was completely new in philosophy and kalām at the time of Abū Hāšim, but it is foreshadowed in al-Ḫwārizmī’s Algebra. In this book, al-Ḫwārizmī distinguishes between proof “by cause”, which consists in transferring a certain geometric deduction to algebra, and proof “by expression”, which operates directly on algebraic expressions, which it reduces analytically. A text by Abū Hāšim devoted to human knowledge that seems to refer to the work of al-Ḫwārizmī suggests, finally, that the close parallel between al-Ḫwārizmī’s doctrine of proof and Abū Hāšim's doctrine of the sign may not be a mere coincidence. Two appendices have been added. The first deals with al-Fārābī’s reading of Abū Hāšim's theory of inference. The second, based on all available data, establishes for the first time the correct and precise dates of Abū Hāšim's life. (shrink)

Substance use disorders (SUDs) constitute a growing global health crisis, yet many limitations and challenges exist in SUD treatment research, including the lack of objective brain-based markers for tracking treatment outcomes. Electroencephalography (EEG) is a neurophysiological technique for measuring brain activity, and although much is known about EEG activity in acute and chronic substance use, knowledge regarding EEG in relation to abstinence and treatment outcomes is sparse. We performed a scoping review of longitudinal and pre-post treatment EEG studies that explored (...) putative changes in brain function associated with abstinence and/or treatment in individuals with SUD. Following PRISMA guidelines, we identified studies published between January 2000 and March 2022 from online databases. Search keywords included EEG, addictive substances (e.g., alcohol, cocaine, methamphetamine), and treatment related terms (e.g., abstinence, relapse). Selected studies used EEG at least at one time point as a predictor of abstinence or other treatment-related outcomes; or examined pre- vs. post-SUD intervention (brain stimulation, pharmacological, behavioral) EEG effects. Studies were also rated on the risk of bias and quality using validated instruments. Forty-four studies met the inclusion criteria. More consistent findings included lower oddball P3 and higher resting beta at baseline predicting negative outcomes, and abstinence-mediated longitudinal decrease in cue-elicited P3 amplitude and resting beta power. Other findings included abstinence or treatment-related changes in late positive potential (LPP) and N2 amplitudes, as well as in delta and theta power. Existing studies were heterogeneous and limited in terms of specific substances of interest, brief times for follow-ups, and inconsistent or sparse results. Encouragingly, in this limited but maturing literature, many studies demonstrated partial associations of EEG markers with abstinence, treatment outcomes, or pre-post treatment-effects. Studies were generally of good quality in terms of risk of bias. More EEG studies are warranted to better understand abstinence- or treatment-mediated neural changes or to predict SUD treatment outcomes. Future research can benefit from prospective large-sample cohorts and the use of standardized methods such as task batteries. EEG markers elucidating the temporal dynamics of changes in brain function related to abstinence and/or treatment may enable evidence-based planning for more effective and targeted treatments, potentially pre-empting relapse or minimizing negative lifespan effects of SUD.

The study aimed to examine the impact of parental influence and media richness on gender stereotypes and career decisions among students at the secondary level in Pakistan. The sample size was 200 students, selected through a simple random sampling technique from government and private schools. Four questionnaires were used to gather data. The data was analyzed quantitatively using the Statistical Package for the Social Sciences. Regression analyses were used to investigate the impact of parental influence on gender stereotypes and media (...) richness influence on gender stereotype beliefs. Furthermore, parental, media, and gender stereotype behavior all have a significant impact on students’ career choices. On the scale of the parental influence and media richness, no significant gender differences were found. It is concluded that parental influence has a greater effect on students’ gender stereotyping behavior and career choices. (shrink)

The COVID-19 pandemic has deeply influenced the tourism and hospitality industry, and it has also reshaped people’s travel preferences and related behaviors. As a result, how prospective travelers perceive travel constraints and their effects on future travel behaviors may have changed to some extent. Besides, such perception arguably varies across gender. Therefore, this research examines the interplay between travel constraints, gender, and travel intentions for facilitating robust tourism recovery by revisiting the Leisure Constraints Model from a gender perspective. Data were (...) collected through a survey from 357 Malaysian prospective travelers. By conducting path analysis and multigroup analysis, it is found that structural and interpersonal constraints impose indirect effects on travel intentions, and gender moderating the effect of structural cost on intrapersonal constraints and effect of intrapersonal constraints on travel intentions. Based on these findings, this research provides theoretical and practical implications into how to adjust their marketing strategies and travel products during the era of “new normal” for tourism policy makers, destination marketers, and related businesses.

Nūr Muḥammad is one of the teachings in Sufism that studies the beginning of the creation of the universe. The Sufis discussed Nūr Muḥammad through God's tajallī (manifestation), and they believed that only Insan Kamil (Perfect Humans) possessed the perfection of His tajallī. This Sufi theory can be comprehended through the dhawqi approach. This research will deal with Nūr Muḥammad's theory of Sufism through the perspective of Tijaniyah Tarekat. The data for this study was obtained through library research utilizing a (...) documentary technique. The collected data will be analyzed using the descriptive analysis method. This study finds that the Tijaniyah Tarekat is a Sufism institution that bases its teachings and practices on the concept of Nūr Muḥammad in the form of ṣalawāt al-fātiḥ and ṣalawāt jawharah al-kamāl. This Tarekat's elucidation of Nūr Muḥammad is also built on and consistent with the explication of authoritative Sufis in Islam's intellectual and spiritual tradition. (shrink)

The notion of 'natural kinds' has been central to contemporary discussions of metaphysics and philosophy of science. Although explicitly articulated by nineteenth-century philosophers like Mill, Whewell and Venn, it has a much older history dating back to Plato and Aristotle. In recent years, essentialism has been the dominant account of natural kinds among philosophers, but the essentialist view has encountered resistance, especially among naturalist metaphysicians and philosophers of science. Informed by detailed examination of classification in the natural and social sciences, (...) this book argues against essentialism and for a naturalist account of natural kinds. By looking at case studies drawn from diverse scientific disciplines, from fluid mechanics to virology and polymer science to psychiatry, the author argues that natural kinds are nodes in causal networks. On the basis of this account, he maintains that there can be natural kinds in the social sciences as well as the natural sciences. (shrink)

This article proposes a reconstitution of the philosophical tenor of al-Fb al-Mawdayyira). It is shown that this work is not only a response to book VI of John Philoponus' Contra Aristotelem, but that its real issues can only be grasped in the context of the author's metaphysical system. Although, for al-Fbī, genuine demonstrations proceed from the cause to the caused, thus following the order of being, it will be explained how he also admits a strictly physical proof of the simple (...) fact, independently of its cause, and that the physical demonstration of the eternity of the world pertains to this type of proof. This physical proof is specifically directed against the Kindian doctrine of creation. (shrink)

This article aims to improve the understanding of corporate governance and environmental reporting literature by analyzing the impact of board gender diversity (BGD) on environmental performance, environmental disclosure, and greenwashing behavior. The panel regression estimation technique with fixed effects was applied to Chinese firm data. As a result, it was found that more women who served on corporate boards enhanced the company's environmental performance and disclosures while limiting greenwashing behavior. The result indicated that women in top management play a constructive (...) role in establishing firms' active environmental initiatives. Furthermore, this relationship was nonlinear and exponentially increased when women's representation reached the threshold of 33.5% representation on board or higher. Based on the findings, no internal bias was found even after other governance and firm-level control factors and probable endogenies were considered and variable biases were omitted. Notably, the results present important implications for regulators and policymakers by highlighting the influential role of BGD in promoting environmentally responsible practices and reducing greenwashing.

Could some social kinds be natural kinds? In this paper, I argue that there are three kinds of social kinds: 1) social kinds whose existence does not depend on human beings having any beliefs or other propositional attitudes towards them ; 2) social kinds whose existence depends in part on specific attitudes that human beings have towards them, though attitudes need not be manifested towards their particular instances ; 3) social kinds whose existence and that of their instances depend in (...) part on specific attitudes that human beings have towards them . Although all three kinds of social kinds are mind-dependent, this does not make them ontologically subjective or preclude them from being natural kinds. Rather, what prevents the third kind of social kinds from being natural kinds is that their properties are conventionally rather than causally linked. (shrink)

This study systematically analyzes the factors that affect consumers’ green purchase intention. Through a comprehensive literature review, the influencing factors of consumers’ green purchase intention are organized into three categories: cognitive factors, consumer individual characteristics, and social factors. Next, a meta-analysis of 54 empirical papers was conducted using Comprehensive Meta-Analysis 3.0 software to quantitatively assess these relationships. The results revealed that green perceived value, attitude, and green trust have a significant positive influence on green purchase intention. Perceived behavior control, perceived (...) consumer effectiveness, and subjective norm also has a strong positive impact on green purchase intention. Collectivism has a positive effect on green purchase intention. Green perceived risk has a significant negative impact on green purchase intention. The study’s findings provide references for enterprises engaged in green product diffusion and organizations responsible for environmental protection. (shrink)

This article has explored the impact of coronavirus disease 2019 -induced decline in consumer durables and mobility on nitrogen dioxide emission in Europe by providing empirical and graphical justifications based on consumer price index and gross domestic product deflator indexes. The empirical estimations show that carbon dioxide and NOx emission along with other greenhouse gases drastically decreased in the wake of COVID-19-induced lockdowns and decrease in the demand of consumer goods in Europe. This means that COVID-19 improved environment in the (...) European region. However, high cost makes COVID-19 an unstable solution to environmental woes where positive impact of COVID-19 on environment achieved in short run cannot be guaranteed in the long run. Besides environment, COVID-19 drastically curtailed economic activities and exposed them to the risk of economic crisis particularly in case of Europe. (shrink)
