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 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.

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.

The purpose of this paper is to evaluate the welfare cost resulted from an increase in food prices in the three most populous countries of south Asia (Pakistan, India and Bangladesh).

The effect of rising food prices on consumer welfare is analyzed by using the compensating variation technique. The measurement of the total consumer welfare effect requires the estimation of price elasticities which are calculated by using linear approximation version of the almost ideal demand system.

The results indicate that cereals (wheat, rice) are relatively price inelastic. However, protein-rich food items like chicken and mutton are relatively more income elastic where consumer welfare declines in all countries mainly for cereals and milk, as these food items are relatively less elastic to price fluctuations.

Pakistan, India and Bangladesh represent together about 37 percent of the total world undernourished population. This study suggests that government should target the most vulnerable consumers (low-income group) to improve the income level in these countries.

It is the first effort to estimate and compare that how food inflation affects the consumer welfare in the most populated countries of South Asia. This type of study is also important for the policy planners to overcome the welfare cost under different setting of price and income so it is an effort toward this direction.

By conducting an online experiment, this paper proposes and tests a conceptual model about the impact of price labeling strategy on consumers' perceived price difference and purchase intention. The authors also analyze differential influences of shopping channels and price levels on documented effects. The paper provides strategic suggestions for online grocery store managers to adopt profit-maximizing labeling decisions.

In a between-subject experiment, the authors simulated a shopping task with eight scenarios by exogenously manipulating price labeling strategies (unit price/retail price), sales channels (online/offline) and price levels (higher/lower than the average price). Participants are randomly assigned to one of the eight scenarios and asked to report their perceived price difference between the stimuli product and the average market price and their purchase intention on the stimuli product.

Experimental results show that compared to the unit price, the retail price increases the perceived price difference. It shows that the unit price increases consumers' purchase intention when the product price is higher than the average market price. However, these effects only exist in the online shopping context.

This paper extends the study of price labeling strategy to an online shopping context and examines the mediation effect of the perceived price difference.

This study aims to examine the key determinants of corporate social responsibility (CSR) disclosure of all listed banks that operate their function in an emerging market, Pakistan.

This study applied the principles of systems-oriented theories such as legitimacy, stakeholder and agency theory. The hypothesis is linking the bank’s social disclosure and its determinants are developed. The relevant data was gathered from the bank’s annual reports and Pakistan Stock Exchange from 2008 to 2018. Further, governance attributes and performance measures are used as the predictor variable and the CSR score as the predicted variable. This study applied panel data analysis on the sampled banks to examine the proposed hypothesis for empirical estimation.

This study’s inclusive results confirm that the hypothesized determinants of board size, foreign directors on board and female directors on board positively impact the CSR disclosure potential. Board size significantly explains the CSR disclosure in all bank samples. The determined performance measures, profitability and liquidity show a significant positive relationship with CSR disclosure except for few exceptions.

This study’s results lack generalizability due to its unique setting; future researchers can extend the research scope in national–international settings and a regional context.

This study enriches the literature on CSR disclosure determinants and is relevant to practice in an emerging context. It can be helpful from a policy perspective; institutions (bodies) that regulate banks should recognize the governance and performance aspects essential to enhancing CSR disclosure and enhancing the bank’s performance hence value.

This research offers empirical evidence that sheds light on the key governance attributes and performance measures that partially affect CSR disclosure and its extent. In doing so, this study’s findings contribute to the literature significantly, along with regulators, shareholders, deposit holders, individual–institutional investors.
