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.

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.

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)

In the recent years, an alarming rise in the incidence of cyber attacks has made cyber security a major concern for nations across the globe. Given the current volatile socio-political environment and the massive increase in the incidence of terrorism, it is imperative that government agencies rapidly realize the possibility of cyber space exploitation by terrorist organizations and state players to disrupt the normal way of life. The threat level of cyber terrorism has never been as high as it is (...) today, and this has created a lot of insecurity and fear. This study has focused on different aspects of cyber attacks and explored the reasons behind their increasing popularity among the terrorist organizations and state players. This study proposes an empirical model that can be used to estimate the risk levels associated with different types of cyber attacks and thereby provide a road map to conceptualize and formulate highly effective counter measures and cyber security policies.

In this article, we examined the relationship between abusive supervision and deviant workplace behavior and the moderating role of an Islamic Work Ethic. Three hundred and thirty‐six employees in different organizations (specializing in software development, medicine, law enforcement, telecommunication, pharmaceutics, and banking) across Pakistan completed our questionnaire. The results revealed that abusive supervision was positively related to deviant workplace behavior. Moreover, the moderation of an Islamic Work Ethic on the relationship between abusive supervision and deviant work behavior was confirmed. The (...) study contributed in many ways. It expanded literature by revealing a weaker relationship between abusive supervision and deviant behavior when Islamic Work Ethic (IWE) was high. It also tested the conservation of resources theory by providing a plausible reasoning of the role of IWE in employee motivation. By integrating IWE as a resource in the workplace, practitioners would learn that the proper use of resources would produce satisfied workers who would not indulge in deviant workplace behaviors.

The construction projects in Pakistan have inherent problems of erroneous planning and schedule development. This dilemma has led to the failure of the majority of construction projects in Pakistan. Earlier researches have tried to curtail the increasing spectrum of inaccurate planning and schedule development. But not many research studies have shed light on the major factor of 2D CAD drawings interpretation problems, which are playing a key role in defective planning and scheduling. Moreover, the role of BIM, i.e., Building Information (...) Modeling with respect to efficient planning, has not been also discussed in detail. This study has concluded a positive impact of BIM on effective planning and scheduling in the construction industry of Pakistan. About 210 responses were obtained from experienced construction professionals of Pakistan and tested via regression analysis in order to validate this argument. It has been analyzed that 2D CAD drawings are now getting primitive and 3D technology BIM is taking its place. BIM is an efficient tool for planning and scheduling. With the start of CPEC and Multi-Billion Dollar investment on infrastructure, construction industry of Pakistan needs to uplift its existing standard in order to meet with international requirements. For this purpose, BIM has been recommended. It will not only assist in attaining flawless planning but will also increase the success rate of CPEC projects in Pakistan. (shrink)

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)

The twenty-first century has seen an increase in ethical misconduct at the workplace, highlighting the need to stimulate discussion on the role of work ethics. The objective of the current study is to extend the literature on work ethics by examining the role of Islamic work ethic in enhancing the task performance of employees. The current study proposes that psychological capital mediates the relationship between Islamic work ethic and task performance. It is also proposed that ethical leadership might act as (...) a boundary condition that boosts the positive relationship between Islamic work ethic and psychological capital. Data were collected in three-time lags from employees working in the service sector of Pakistan through the questionnaire. The results supported the mediation and moderation hypothesis, confirming that psychological capital mediates the relationship between Islamic work ethic and task performance. Ethical leadership moderates the relationship between Islamic work ethic and psychological capital. The results offer implications for theory and practice. Limitations and future research directions are also discussed. (shrink)

This book is the first study of the ontological system of Alexander of Aphrodisias (floruit c. 200 AD), famous for his commentaries on the works of Aristotle.

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.

This article is devoted to the interpretation of the object of metaphysics and theoretical sciences proposed by Alexander of Aphrodisias (fl. 200 AD). I shall propose two conjectures on crucial passages from his commentary on the Metaphysics (In Metaph. 245.37-246.6 et 246.6-13) and, on this new textual basis, defend the thesis according to which Alexander articulated a primary fundamental philosophy, devoted to immobile substances and treated by Aristotle in Metaphysics Λ, and a philosophy, if one can say so, more primary (...) but less ontological, hence less fundamental, devoted to the general structure of being and treated by Aristotle in Metaphysics Γ. The latter seems to differ from the Categories, according to Alexander, in that in the Categories, Aristotle studies the general classes of beings as general, while in Metaphysics Γ, he studies them as beings.

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 importance of the hidden curriculum is recognised as a practical training ground for the absorption of medical ethics by healthcare professionals. Pakistan’s healthcare sector is hampered by the exclusion of ethics from medical and nursing education curricula and the absence of monitoring of ethical violations in the clinical setting. Nurses have significant knowledge of the hidden curriculum taught during clinical practice, due to long working hours in the clinic and front-line interaction with patients and other practitioners.

Design problems in structural engineering are often modeled as differential equations. These problems are posed as initial or boundary value problems with several possible variations in structural designs. In this paper, we have derived a mathematical model that represents different structures of beam-columns by varying axial load with or without internal forces including bending rigidity. We have also developed a novel solver, the LeNN-NM algorithm, which consists of weighted Legendre polynomials, and a single path following optimizer, the Nelder–Mead algorithm. To (...) evaluate the performance of our solver, we have considered three design problems representing beam-columns. The values of performance indicators, MAD, TIC, NSE, and ENSE, are calculated for a hundred simulations. The outcome of our statistical analysis points to the superiority of the LeNN-NM algorithm. Graphical illustrations are presented to further elaborate on our claims. (shrink)

Handwritten text recognition is considered as the most challenging task for the research community due to slight change in different characters’ shape in handwritten documents. The unavailability of a standard dataset makes it vaguer in nature for the researchers to work on. To address these problems, this paper presents an optical character recognition system for the recognition of offline Pashto characters. The problem of the unavailability of a standard handwritten Pashto characters database is addressed by developing a medium-sized database of (...) offline Pashto characters. This database consists of 11352 character images. Enriched feature extraction techniques of histogram of oriented gradients and zoning-based density features are used for feature extraction of carved Pashto characters. K-nearest neighbors is considered as a classification tool for the proposed algorithm based on the proposed feature sets. A resultant accuracy of 80.34% is calculated for the histogram of oriented gradients, while for zoning-based density features, 76.42% is achieved using 10-fold cross validation. (shrink)

Somatic complementation by fusion of two mutant cells and mixing of their cytoplasms occurs when the genetic defect of one fusion partner is cured by the functional gene product provided by the other. We have found that complementation of mutational defects in the network mediating stimulus‐induced commitment and sporulation of Physarum polycephalum may reflect time‐dependent changes in the signaling state of its molecular building blocks. Network perturbation by fusion of mutant plasmodial cells in different states of activation, and the time‐resolved (...) analysis of somatic complementation effects can be used to systematically probe network structure and dynamics. Time‐resolved somatic complementation quantitatively detects regulatory interactions between the functional modules of a network, independent of their biochemical composition or subcellular localization, and without being limited to direct physical interactions.

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 discusses the haul stage which is held once a year on the date of death of the fourth former President of the Republic of Indonesia, namely Abdurrahman Wahid (Gus Dur), which demonstrates harmonious relations between adherents of different religions in Indonesia.

Analysing YouTube videos, this study finds that interfaith dialogue forms (...) have been reflected in: (1) declarations of a cross-religious ideology, (2) the involvement of interfaith figures, and (3) the inclusivist discourses themselves. Gus Dur’s haul, thus, has provided collaborative spaces wherein interfaith dialogue value can be sustainably structured.Contribution: This research contributes to exploration of the haul stage, which takes place annually on the death anniversary of former Indonesian President Abdurrahman Wahid (Gus Dur).

I will begin by proposing a taxonomy of taxonomic positions regarding the mind–brain: localism, globalism, revisionism, and contextualism, and will go on to focus on the last position. Although some versions of contextualism have been defended by various researchers, they largely limit themselves to a version of neural contextualism: different brain regions perform different functions in different neural contexts. I will defend what I call “environmental-etiological contextualism,” according to which the psychological functions carried out by various neural regions can only (...) be identified and individuated against an environmental context or with reference to a causal history. While this idea may seem innocuous enough, it has important implications for a structure-to-function mapping in the mind and brain sciences. It entails that the same neural structures can subserve different psychological functions in different contexts, leading to crosscutting psycho-neural mappings. I will try to illustrate how this can occur with reference to recent research on episodic memory. (shrink)

The existing research aims to seek the herding effects on stock returns at the industry level in Pakistan Stock Exchange. Moreover, the relationship between stock returns and herding has been studied by taking some macroeconomic and fundamental control variables. Herding is actually imitating other’s behaviour. This phenomenon indicates a situation where the investors follow the crowed and ignores their personal information, despite knowing the correctness of their information. Herd behaviour may drive from fundamental factors leading to efficient markets. However, it (...) may not be associated with fundamental information causing unstable prices. The stock price data of PSX listed companies from 1999 to 2017 have been the point of focus. The underlying herding measure was the cross-sectional absolute deviation, proposed by Chang et al.. The significant analysis technique facilitating the current research is pooled mean group /panel autoregressive distributed lag approach. Findings revealed that some sectors are evident for positive effect of herding on stock returns, whereas some others are witnessed for its negative effects on stock returns, in both long run and short run. As far as the control variables are concerned, they demonstrated both significant and insignificant effects on stock returns in different sectors of PSX. The study has important implications for policymakers. (shrink)

Drawing on the theory of engagement, the present study aims to examine the outcomes of the co-creation experience in a realistic co-creation setting, a hotpot restaurant. To this end, the current research links the relationship marketing literature to hospitality and tourism research and formulates a novel framework by incorporating tourists’ co-creation experience, brand evangelism, brand trust, and brand passion in an integrated conceptual model. Using a quantitative research design, a total of 453 international tourists were surveyed in China. The findings (...) revealed that co-creation experience dimensions positively impact brand evangelism, trust, and passion. Additionally, we found that brand trust and brand passion positively affect brand evangelism. We also confirmed the mediating effect of brand trust and brand passion in bridging the co-creation experience and brand evangelism. This study offers valuable insights for restaurant brand managers regarding attracting and engaging foreign travelers with their service businesses. (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)

Many researchers are currently showing interest in researching consumers who are purchasing the products with the help of new tools, and new kinds of markets are emerging rapidly. M-commerce is a prevalent mode of marketing and is famous among young people of Pakistan. Current research is planned to check the status of consumer purchase intentions (PIs) using perceived influence, virtual interactivity, brand image, and brand expected value among customers who purchase their products with the help of m-commerce. Data was collected (...) from customers who were engaged in buying with the help of m-commerce by using the convenience sampling technique and 227 complete questionnaires were used in final analysis. This research examines the direct impact of perceived influence, virtual interactivity, brand image, and brand expected value on PIs and finds the indirect effect of brand image and brand expected value on the relationships of perceived influence and virtual interactivity with PIs. Results indicate that all the hypotheses of direct relationships are accepted except the hypothesis for the relation of virtual interactivity with consumer PIs.
