The purpose of the present study is to explore a three-dimensional rotating flow of water-based nanofluids caused by an infinite rotating disk.

Mathematical formulation is performed using the well-known Buongiorno model which accounts for the combined influence of Brownian motion and thermophoresis. The recently suggested condition of passively controlled wall nanoparticle volume fraction has been adopted.

The results reveal that temperature decreases with an increase in thermophoresis parameter, whereas it is negligibly affected with a variation in the Brownian motion parameter. Axial velocity is negative because of the downward flow in the vertical direction.

Two- and three-dimensional streamlines are also sketched and discussed. The computations are found to be in very good agreement with the those of existing studies in the literature for pure fluid.

The aim of the case is to understand the performance management system of academic staff members in higher education institution. Furthermore, students would be able to compare two performance appraisal policies and analyze which one could better serve the purpose considering the context of educational institution. The case would help students understand the performance dynamics of the academic staff and how the performance management system in place affect employees.

The case study presents a troubling situation faced by Asim Khan, a newly appointed director of the Midland University, regarding retention of the faculty. Upon joining Midland, Khan noticed a trend that faculty who was serving the university from many years are leaving the organization one after the other. He decided to revise the faculty policies that he believed was the root cause of faculty turnover in Midland. He formulated a committee to review the existing policies and revamp if required. The committee identified some flaws in the faculty appraisal policy in place at that time and formulated a new one with the consultation of top management. However, when the new appraisal policy was presented to the faculty, few faculty members raised their eyes over a few aspects of the proposed policy. As the new academic year was approaching, Khan had to make an important decision after critically analyzing the pros and cons of both policies that which of the two should be followed for the upcoming year’s appraisals.

The case can potentially be used in the post-graduate courses in MBA programs offering a major in human resource management.

The purpose of this study is to examine the drivers and barriers of travel behavior associated with tourist behavior during/post-COVID-19 pandemic to provide a knowledge base as well as an agenda for future research.

The authors utilized the Systematic Literature Review (SLR) technique for searching the articles published in Web of Science (WOS) and Scopus, to identify the main drivers and barriers affecting the tourist behavior during/post-COVID-19 pandemic. Eventually, 47 articles were chosen for the final analysis.

The findings are reported in three sections, (1) quantitative research profile, (2) qualitative synthesis and (3) future agenda. This study addresses the nuanced questions regarding the significant change in tourist travel behavior, emotional dynamics and a detailed understanding of mechanisms, such as which drivers and barriers affect tourist behavior in a particular destination. Drivers and barriers to tourist travel behavior were characterized in personal-related, destination-related, and health-related factors. Moreover, this study provides thought-provoking ideas in theory, policy and practice in the field of tourism and hospitality.

This study has three limitations, as follows. First, the authors searched only two databases, Scopus and Web of Science, due to which the authors might be missing some related studies existing on the other databases. Although these databases provide an extensive range of academic literature, further studies could extend the data collection from the other databases (e.g. via Taylor & Francis). However, our systematic literature review (SLR) coverage is quite extensive, since journals are listed on these three main databases. Second, the authors followed a main study search protocol based on the synonyms and related keywords, however, some of the studies that may be related to the tourist behavior towards the destination are missing on account of the lack of our keywords in there, title, author, keyword and abstract. Furthermore, future research could endeavor to add other keywords to expand the results of studies. Third, although the accurate analysis was conducted to reduce subjectivity in identifying themes for drivers and barriers of tourist behavior, future studies on categorization could work to ensure that other sub-themes categorize.

The recent study has some key practical implications. First, this study is valuable for all the stakeholders in a unique way, including destination managers, academicians and policymakers, because it provides insight into barriers and drivers that influence the development of tourist behavior towards the destination. Second, the current study also offers practical implications for people involved in tourism service industries including governments and private businesses. Policymakers and other leaders are increasingly interested in harnessing the economic potential of tourism. Therefore, identifying the barrier which is inhibiting the tourist traffic towards the destination is beneficial to understand and effectively develop strategies to minimize the effect of such factors. Moreover, drivers and barriers of tourist behavior towards the destination in the COVID-19 pandemic situation towards the destination may help to create a framework for the development of destinations according to the current vulnerable situation. Third, current findings suggest that tourism marketers understand the drivers and barrier constructs found in this study and tailor their marketing strategies for attracting existing and new tourists. For instance, marketers should understand the drivers and barriers of tourist behavior for effective strategy development to increase the positive effect of drivers and to reduce the negative effect of barriers.

This is the first systematic literature review on the impact of drivers and barriers of tourist travel behavior. This paper analyses the methods and approaches that have been used in the previous literature to examine the drivers and barriers of tourist travel behavior. The paper ends with the research implication and limitations of the studies.

The present study intends to measure buying intention of Generation Z (Gen Z) on social networking sites (SNSs) incorporating perceived risk with the social commerce adoption model (SCAM).

Data were collected via an online questionnaire, and the study used a total of 349 accurate and useable responses. The population of the study includes Indian young consumers coming from the Gen Z cohort. Data were analyzed using SPSS 20 and AMOS 22.0. The proposed hypotheses were statistically tested.

The empirical results show that perceived risk is a significant and strong predictor of perceived usefulness that, in turn, negatively influences buying intention. Among all the constructs of SCAM, perceived usefulness is the most influential and strongest predictor of buying intention. The proposed model explained approximately 34% of the variance in the behavioral intention.

Based on the findings of this study, many theoretical and practical implications may be inferred that can be used to make recommendations to social commerce companies and help them understand the buying intention of Gen Z.

There are many studies that have examined buying intention and a few have measured it on Gen Z. The present study is novel in itself as it has measured the buying intention of Gen Z using the SCAM in the Indian context. Hence, the present research attempts to comprehend the variables influencing buying intention and analyses the relationship between these factors in the social media setting.

This paper aims to examine the determinants that influence bank users’ acceptance for Islamic financial technology (FinTech) services by extending the technology acceptance model (TAM) in the Malaysian context.

The survey was conducted using convenience sampling. Moreover, 205 responses were gathered from users of the Islamic bank. On the same note, the literature on determinants of Islamic FinTech acceptance and TAM was reviewed as well in a bid to contribute to the factors that are instrumental in determining the acceptance of FinTech services.

Findings of the study reveal that Islamic FinTech’s services acceptance is determined by perceived ease of use, perceived usefulness and also by another variable, which is consumer innovativeness (CI). On the contrary other factors, self-efficacy and subjective norms are found not to be influential in determining Islamic FinTech’s acceptance by Islamic banking users.

TAM is extended in the context of Islamic FinTech. A new variable, namely, CI is tested using TAM. CI is yet to be tested, therefore, this paper will be a useful reference for the policymakers, academicians and future researchers.

Corona viruses have spiked structure and enveloped glycoproteins in their structure, along with specific proteins in membranes. The mode of action of COVID-19 consists of three phases, i.e. viral replication, immune hyperactivity and pulmonary destruction. However, angiotensin-converting enzyme is an essential receptor that causes COVID-19. After infecting any individual, COVID-19 develops in specific pattern with the following stages: replication stage and adaptive immunity stage. After adaptive immunity stage, the clinical symptoms of patient include cough, fever, runny nose, shortness of breath and many more. To cope with this COVID-19, food and nutrition played an important role. The purpose of this review article is to emphasize the significance of food and immunity to reduce COVID-19 attack among susceptibles.

In the present era, corona virus, a member of crown-shaped type, created a pandemic situation around the globe owing to its capability to move from human to animals and vice versa. This virus can transfer its 35% infection to the individuals. Contemporarily, this outbreak was observed in Wuhan, China in December 2019 and affected a huge number of communities by spreading like common flu. However, after investigation, it was revealed that COVID-19 is different from common flu regarding respiratory illness created by this novel coronavirus along with its taxonomy.

Over and above to all the aforementioned food safety concerns, it is suggested to use sufficient supply of green leafy vegetables along with fiber-rich foods such as legumes, beans, whole grains and vegetables. It is further good for health to get all these varieties whole and organic. The individuals should use probiotics (lactobacillus) on daily basis as a source of diary probiotic that can further bind to the virus directly and then can inhibit the viral attachment with body cells; also the probiotics are claimed to enhance the immune system of the body.

In the case of fruits and vegetables purchased, it must be thoroughly washed with water and then disinfected; after pat drying, these fruits and vegetables can be moved to the refrigerator and stored along with other foods. During the outbreak of COVID-19, the partially cooked or ready-to-eat foods should be avoided, especially eggs, meat, meat products, milk and milk-related products. On the other side, nuts should not be consumed; if required, then it must be properly roasted at home before consumption.

The baked product right after coming out of oven is completely safe; however, these are contaminated during handling such as crumb in case of bread and with knives; so in the breakout of any viral attack, the individuals should avoid slicing of the bread. Moreover, it is recommended to place the baked products in personal bags instead of bulk quantity. Before the consumption, the baked products should be toasted, microwaved or heated with the help of pan (traditional) to reduce the amount of viral load.

Dietary supplements are taken by most of the people on daily basis or sporadically especially when they are suffering from inflammation or cold. They have options while selecting these types of supplements such as probiotics, Echinacea, omega-3 fatty acids, vitamins D and E, calcium glucosamine, garlic and iron. These supplements are beneficial for the group of population who do not eat diversity of food as sufficient amount of essential nutrients is provided through this pathway.

This work is original in its novelty.

Entrepreneurial orientation is among the vital factors that contribute to performance, especially for small and medium-sized enterprises (SMEs). However, the empirical studies provide mixed results and call for new studies to examine this relationship. Therefore, this study aims to determine the entrepreneurial orientation's (EO) direct and indirect impact (via entrepreneurial competencies) on firm performance. Additionally, the moderating role of environmental dynamism is also tested in entrepreneurial competencies and firm performance relationships.

The data (N = 332) were collected from managerial rank employees, using a self-administered questionnaire, working in different SMEs in Pakistan. In addition, structural equation modeling (SEM) was executed using SmartPLS 3.2.

The study's results demonstrate that EO positively influences entrepreneurial competencies and firm performance, and entrepreneurial competencies also mediate the relationship between EO and performance. Additionally, environmental dynamism strengthens the positive relationship between entrepreneurial competencies and performance.

This study identifies that entrepreneurial competency is the missing link between EO and firm performance, due to which the relationship between them is indecisive. This study also contributes to the contingency perspective by explaining the role of environmental dynamism as a boundary condition in strengthening the relationship between entrepreneurial competencies and SMEs' performance in an emerging economy.

The current study provides new insights into the relationships between knowledge development (KD) and sustainable supply chain performance (SSCP) by exploring the mediating effects of entrepreneurial orientation (EO) in terms of innovativeness, proactiveness and risk taking.

Data were collected by questionnaire survey from 242 manufacturing organizations. Structural equation modeling (SEM) was used to test the hypotheses.

The results reveal that innovativeness and proactiveness have full mediating effects on the relationship between KD and SSCP. Though KD is negatively related to risk taking and has insignificant indirect effect on SSCP via risk taking, the mediating effect of risk taking remains moderate positive on the relationship between KD and SSCP.

Given that the current study focuses on manufacturing sector, future research is needed for more comparative studies conducted in different sectors and cultural contexts. The negative link between KD and risk taking also warrants future investigation.

Organizations may reduce their level of risk taking due to the increase in KD. However, in order to enhance SSCP, risk taking is still needed as it mediates the relationship between KD and SSCP.

The mediating effects of innovativeness, proactiveness and risk taking on the relationship between KD and SSCP are unknown. Current study aims to address this gap.

The aim of this paper is to reconcile the diverging opinions among Islamic economists toward the concept of scarcity and to present a holistic model of scarcity and abundance from a Qur’anic perspective.

Analyses of both interviews and texts were performed. The method in studying scarcity from Islamic perspective consisted of semi-structured interview with five experts in the field of Islamic economics and development.

One major implication of this study is that the concept of scarcity as it is postulated by mainstream economics tends to clash with the Islamic worldview, as it does not have any reference in Islam. Scarcity can act as a phenomenon in economic activities but not as the defining concept in Islamic economics.

Practically, this paper will contribute to the making of the first lecture of the course of Islamic economics.

Socially, this paper will contribute to the process of transforming the science of economics and Islamic economics for a sustainable tomorrow.

This paper is a fundamental paper that addresses some aspects from critical realism and transcendental idealism into the making of Islamic economics. Not only that the discussion on the concept of scarcity in Islamic economics is limited and seems to be lacking; in addition, this paper offers a critical discussion on the validity of the concept of scarcity in economics from a critical perspective.

Though customer experience (CX) is identified as a key research priority, empirically led insight with tourism consumers' resulting emotional attachment (EA) and customer loyalty (CL) remains scarce, particularly during the COVID-19 crisis. Adopting service-dominant logic, this study develops a model that investigates the impact of customer engagement (CE) and customer co-creation (CC) on CX, which consequently effects EA and CL during the COVID-19 crisis in the tourism industry. First, our results suggest that CE and CC positively affect tourism CX. Second, results revealed the CX's significant positive effect on EA and CL. Third, findings confirmed the CE's and CC's indirect impact on EA and CL, as mediated via CX in pandemic situations. Our study offers key implications for destinations to develop tactics in surviving during a pandemic to rebuild tourism.
