The purpose of this paper is to investigate the relationships between students’ use of social media, their academic performance and creativity in the digital era.

This research used a survey strategy for collecting primary data required for this study from 334 students of undergraduate programs at Chinese universities who were sampled through a non-probability convenience approach.

The findings of the study reveal that students’ use of social media is positively associated with students’ academic performance and creativity. In addition, intrinsic motivation was found to be a mediating reason in the relationships between students’ use of social media and students’ academic performance and creativity.

This study explored an important role of intrinsic motivation as a mediator in the relationships between students’ use of social media and their positive outcomes. Studying the use of social media by students to their positive study outcomes is also practically important for students, educationalists and other policymakers.

The purpose of this paper is to explore the scope of robust dispersion control charts in a distribution-free environment, which is a specific case of non-normal control charts. These control charts are skewness-based structures designed to monitor skewed-type processes whilst equally performing under symmetric processes. Moreover, the choice of a suitable control chart for a particular non-normal situation is also suggested.

The probability control limits approach is considered as an alternative way to determine the skewness-based structure of dispersion control charts. The proposals of five robust and two conventional Shewhart-type dispersion control charts are suggested as efficient competitors of skewness correction (SC) dispersion control charts. The evaluation of robust proposals and competing dispersion control charts is done through false alarm rate (FAR) and probability to signal (PTS) measures.

The proposed dispersion control charts are found robust and efficient alternatives of SC dispersion control charts in both normal and non-normal distributions. The FARs and PTS properties of proposed control charts are impressive in all studied cases, and a real-data example also verifies the dominance of proposed control charts.

Conventional dispersion control charts quickly lose their efficiency as underlying process distribution deviates from normality; however, robust control charts emerge as most suitable candidates in such situations. This paper proposes the idea of robust dispersion control charts under a distribution-free structure for the skewed-type process, which is not yet explored.

The Sustainable Development Goal (SDG) 16 outlines sustainability as associated with peace, good governance and justice. The perception of international tourists about security measures and risks is a key factor affecting destination choices, tourist flow and overall satisfaction. Thus, we investigate the impact of armed forces personnel, prices, economic stability, financial development and infrastructure on tourism.

This research used data from 130 countries from 1995 to 2019, which were divided into four income groups. This study employs a two-step generalized method of moments (GMM) technique and a novel tourism index comprising five relevant indicators of tourism.

A 1% increase in armed forces personnel expands tourism in all income groups – 0.369% High Income Countries (HICs), 0.348% Upper Middle Income Countries (UMICs), 0.247% Lower Middle Income Countries (LMICs) and 0.139% Low Income Countries (LICs). The size of the tourism-safety coefficient decreases from high to low-income groups. The impact of inflation is significantly negative in all panels, excluding LICs. The reduction in tourism was 0.033% in HICs, 0.049% in UMICs and 0.029% in LMICs for a 1% increase in prices. The increase in the global tourism index is more in LICs (0.055%), followed by LMICs (0.024%), UMICs (0.009%) and HICs (0.004%) for a 1% expansion in the gross domestic product (GDP)/capita growth. However, the magnitude of the growth-led tourism impact is greater in developing countries. A positive impact of foreign direct investment (FDI) inflow was found in all panels like 0.016% in HICs, 0.050% in UMICs and 0.119% in LMICs for a 1% increase in FDI inflow. The rise in the global tourism index is 0.097% (HICs), 0.124% (UMICs) and 0.310% (LMICs) for a 1% rise in the financial development index. The increase in the global tourism index is 0.487% (HICs), 0.420% (UMICs) and 0.136% (LICs) for a 1% rise in the infrastructure index.

Empirical analysis infers important policy implications such as (a) establishment of a peaceful environment via recruitment of security personnel, use of safe city cameras, modern technology and law enforcement; (b) provision of basic facilities to tourists like sanitation, drinking water, electricity, accommodation, quality food, fuel and communication network and (c) price stability through different tools of monetary and fiscal policy.

First, it explains the effect of security personnel on a comprehensive index of tourism instead of a single variable of tourism. Second, it captures the importance of economic stability (i.e., economic growth, financial development and FDI inflow) in the tourism–peace nexus.

The present research aims to empirically test the “Barriers to abusive supervision model” to find how employee-related (core self-evaluations) and situational factors (perceived job dependency) make an employee trapped in the spiral of supervisory abuse. In addition, the work–family spillover lens is used to explain how employees' retaliation is targeted at their families in response to abuse from their bosses.

The current study has employed a three-wave longitudinal moderated mediation design and analysed data from 265 employees working in the hospitality industry of Pakistan.

The results of this study have shown that low core-self evaluations put employees in a spiral of supervisory abuse and they instil aggression towards their families. This association is further strengthened when employees are dependent on their job.

This study is one of the first to use the “Barriers to Abusive supervision” model to answer who and in which conditions tend to trap in the spiral of abuse and integrate the work-to-family interface model for elaborating the outcomes to the family domain.

The main purpose of this study is to identify the socioeconomic determinants of dropout from primary schools and to give policy suggestions to address the issue.

A total of 600 dropout and enrolled respondents were selected from 60 government primary schools of district Chiniot. School heads and parents of dropout children were taken as samples. The results were obtained by employing the Probit regression model.

Numbers of family members, age of the family head, exchange marriage and poverty status have positive relationship with dropout from primary schools. The findings revealed a higher rate of dropout among girls, which is a major cause of concern.

Education is regarded as a basic human right and a valuable human capital. It is included in Millennium Development Goals to achieve universal primary education and in Sustainable Development Goals as quality education. Underdeveloped countries are facing the problems of high dropout and lack of quality education, especially in Pakistan. These problems need to be addressed to keep pace with developed nations and to meet development goals.

It is recommended that government should create employment opportunities, family planning programs, legislature measures on exchange marriage and child labor. The involvement in co-curricular activities in learning and usage of audio-visual aids in the teaching process can improve the enrollment in the primary schools.

The purpose of this paper is to enhance the longevity and improve the succession process in small family businesses sustaining in Pakistan. Family businesses perform an active role in economic development of any country. Statistics shows, 30/13/3 business transfers into subsequent generation in the interfamily business (Ward, 2016).

Data are collected from 365 respondents who were either incumbents or successor in 135 small family businesses in Pakistan. Simple linear regression and process control analysis by Andrew Hayes are used for moderating variable analysis in SPSS20.

The results show that customer focus management, business strategies and governance board have a significant positive impact on the succession process of small family business in Pakistan. There is negative significant moderating impact of education on business strategies and customer focus management while there is no moderating impact of education over governance board and satisfaction with succession.

This study will help the family business incumbents to focus deliberately on the factors that influence the succession process so that business could be transferred to the subsequent generation successfully.

The previous research does not show the effect of education at different levels and importance of customer focus management toward the succession process.

The purpose of this study is to investigate safe-haven properties of environmental, social and governance (ESG) stocks in global and emerging ESG stock markets during the times of COVID-19 so that portfolio managers and equity market investors could decide to use ESG stocks in their portfolio hedging strategies during times of health and market crisis similar to COVID-19 pandemic.

The study uses a wavelet coherence framework on four major ESG stock indices from global and emerging stock markets, and two proxies of COVID-19 fear over the period from 5 February 2020 to 18 March 2021.

The results of the study show a positive co-movement of the global COVID-19 fear index (GFI) with ESG stock indices on the frequency band of 32 to 64 days, which confirms hedging and safe-haven properties of ESG stocks using the health fear proxy of COVID-19. However, the relationship between all indices and GFI is mixed and inconclusive on a frequency of 0–8 days. Further, the findings do not support the safe-haven characteristics of ESG indices using the market fear proxy (IDEMV index) of COVID-19. The robustness analysis using the CBOE VIX as a proxy of market fear supports that ESG indices do not possess safe-haven properties. The results of the study conclude that the safe-haven properties of ESG indices during the ongoing COVID-19 pandemic is contingent upon the proxy of COVID-19 fear.

The findings have important implications for the equity investors and assetty managers to improve their portfolio performance by including ESG stocks in their portfolio choice during the COVID-19 pandemic and similar health crisis. However, their investment decisions could be affected by the choice of COVID-19 proxy.

The authors believe in the originality of the paper due to following reasons. First, to the best of the knowledge, this is the first study investigating the safe-haven properties of ESG stocks. Second, the authors use both health fear (GFI) and market fear (IDEMV index) proxies of COVID-19 to compare whether safe-haven properties are characterized by health fear or market fear due to COVID-19. Finally, the authors use the wavelet coherency framework, which not only takes both time and frequency dimensions of the data into account but also remains unaffected by data stationarity and size issues.

This research aimed to find out both direct and mediating relationships between the fear of COVID-19 (FC) and the usage of digital financial services (UDFS) via mediator financial anxiety (FA). It also attempted to ascertain the moderated effect of education of small and medium-sized enterprise (SME) owners (ESO), i.e. business degree holders (BDH) vs nonbusiness degree holders (NBDH), in the relationship between FC and the UDFS.

This research employed a simple random sampling technique. In total, 387 complete responses were collected from Pakistani SMEs. The complete analysis was performed using Statistical Package for the Social Sciences (SPSS) 23, AMOS 24, Process Marco 4.1, and Interaction 1.7.

According to the findings, FC leads to UDFS and FA mediates this relationship. Additionally, the findings show that the ESO between FC and UDFS was moderated. However, conditional analysis shows that BDH-SME owners strengthened the moderated relationship between FC and UDFS compared to NBDH-SME owners, who did not show any relationship.

Policymakers might use the study's findings to promote business education, which has been recognized as essential for making sound financial decisions. Finally, because the study is cross-sectional, the authors are unable to draw definitive generalizations.

The key novelty of this research work lies in the inclusion of FA as a mediator and the education of SME owners as a moderator in understanding the relationship between FC and the UDFS. This study illuminated the positive aspects of the COVID-19 epidemic based on the theory of emotional finance, risk avoidance theory and theories of emotion.

The purpose of this study is to modify guar gum (GG) into guar gum acetate (GGA) and phthaloyl guar gum (PHGG) by transesterification and phthaloylation, respectively.

GG has been modified into GGA through transesterification reaction between GG and vinyl acetate and PHGG through esterification reaction with phthalic anhydride. The modified GG was characterized by solubility test, Fourier-transform infra-red (FTIR) spectroscopy, proton nuclear magnetic resonance (¹H NMR) spectroscopy, X-ray diffractometry (XRD) and thermogravimetric analysis. Swelling properties of GGA and PHGG hydrogels in water were evaluated.

These two types of modified GG have better solubility such as in dimethyl sulfoxide and N,N-dimethylformamide but no true organosolubility was achieved. The modifications were confirmed through FTIR with new absorption peaks at 1,733 cm⁻¹ for GGA and 1,709 cm⁻¹ for PHGG coupled with observed substitution peaks at 1.80 to 2.20 ppm and 7.40 to 7.90 ppm, respectively, from ¹H NMR spectroscopies. XRD revealed both GGA and PHGG are less crystalline than native GG. GGA was found to be more thermally stable than native GG, whereas PHGG was slightly less thermally stable than native GG. The swelling property in distilled water for native GG, PHGG and GGA was 918.43 ± 46.62%, 537.04 ± 2.87% and 393.04 ± 13.42%, respectively.

The GGA and PHGG hydrogels are expected to be useful for biomedical fields such as tissue engineering and drug-delivery.

Modifications of native GG into GGA using vinyl acetate and PHGG using phthalic anhydride are novel.

This study aims to examine how corporate financial flexibility, financial sector development and the regulatory environment influence corporate investment decisions in an emerging economy after controlling for several macroeconomic factors.

The authors estimated random-effects models to empirically examine the impacts of corporate financial flexibility, banking sector development, equity market development, regulatory quality and corruption on corporate investment decisions. The empirical analysis is based on an unbalanced annual panel data set of a sample of 198 non-financial firms listed on the Pakistan Stock Exchange for the period 1992–2018.

The results show that financially flexible firms tend to invest more. The increased banking sector development, stock market development and better regulatory quality play a pivotal role for enabling firms to increase their investment ability. However, the results reveal that corruption acts as a barrier and reduces corporate investments during the examined period. The results suggest that unused borrowing capacity is a good source of financial flexibility. These results strongly support the pecking order theory, which explains why firms incline toward internal sources for financing their investments and why they prefer debt to equity when go for external financing.

The empirical findings of the study enable corporate managers to make better financing and investment decisions by understanding the significance of the attainment and maintenance of the corporate financial flexibility to enhance firm value. Furthermore, the findings enable corporate managers to examine and understand the role of banking sector development (BSD), equity market development (EMD), regulatory quality and the role of corruption in affecting corporate firms' investment ability, allowing them to make appropriate investment decisions, especially from an emerging economy perspective. The findings also help investors in making appropriate investment decisions while they are purchasing financial assets. Finally, the findings of the study have some implications for regulators as well. Specifically, the findings suggest that the authorities should implement economic and financial policies favoring banking sector as well as equity market development to enhance corporate investment.

The study significantly adds to the literature by examining the impact of financial flexibility, financial sector development and regulatory environment on corporate investment decisions. According to the authors' knowledge, the empirical evidence examining the impact of all of these factors on corporate investment is very scarce. Therefore, this study is an effort to fill the gap left in the literature.
