Social network sites (SNSs) are the most essential communication tools among students, especially at higher levels of education. The purpose of this study is to identify and examine the factors that have an impact on the academic performance of students by using SNSs. The suggested factors that affect student performance are interactions with colleagues, interactions with instructors, engagement, and cooperative learning. The primary research objective of this case study is to determine which factors affect students' academic performance while using SNSs. In this study, i.e., quantitative research, a survey was conducted to analyze the factors associated with student's performance, among undergraduate and graduate students during the 2016/2017 academic session. The survey data were analyzed using descriptive statistical correlations and regression models. The findings indicate that SNSs have a significant positive effect on interactions with colleagues, interactions with instructors, engagement, cooperative learning, and student performance. In addition, interactions with colleagues and instructors while using SNSs simplify the communication between students and instructors, which leads to an enhancement of cooperation, knowledge sharing, and improvement and development of the learning process and also provides many learning chances.
This study examines the impact of three macro uncertainty factors: economic policy uncertainty (EPU), political instability (PIS), and cultural uncertainty avoidance (UA), on corporate environmental, social and governance (ESG) performance and carbon emission reduction targets. Additionally, we examine whether these macro factors are affected by the profitability of the company. Using an unbalanced sample of companies located in the USA, China, and the UK during the period 2013–2020, results show that during times of economic uncertainty, companies are more likely to engage in ESG activities, including establishing emission reduction targets. Companies in countries with lower levels of political stability (PS) exhibit greater levels of social and environmental engagements, and companies operating in societies that tolerate risks, including the risk associated with climate change, are more likely to have better ESG performance and be committed to emission reduction targets. The results also suggest that profitable companies are more likely to deal with uncertain environments successfully, as they have the required resources to invest in ESG. The study suggests several practical implications for managers and policymakers.
Biorefineries provide economic, environmental, and social benefits towards sustainable development. Because of the relatively small size of typical biorefineries compared to oil and gas processes, it is necessary to evaluate the options of decentralized (or distributed) plants that are constructed near the biomass resources and product markets versus centralized (or consolidated) facilities that collect biomass from different regions and distribute the products to the markets, benefiting from the economy of scale but suffering from the additional transportation costs. The problem is further compounded when, in addition to the economic factors, environmental and safety aspects are considered. This work presents an integrated approach to the design of biorefining facilities while considering the centralized and decentralized options and the economic, environmental, and safety objectives. A superstructure representation is constructed to embed the various options of interest. A mathematical programming formulation is developed to transform the problem into an optimization problem. A new correlation is developed to estimate the capital cost of biorefineries and to facilitate the inclusion of the economic functions in the optimization program without committing to the type of technology or the size of the plant. A new metric called Total Process Risk is also introduced to evaluate the relative risk of the process. Life cycle analysis is applied to evaluate environmental emissions. The environmental and safety objectives are used to establish tradeoffs with the economic objectives. A case study is solved to illustrate the value and applicability of the proposed approach.
PurposeThe authors reinforce the existing literature on the effect of overall globalization on institutional quality (IQ), while incorporating the effects of economic, political and social aspects of globalization, human capital, government expenditure and population growth. To this end, the authors estimate panel data models for a sample of 36 member countries of the Organization of Islamic Cooperation (OIC) during 1984–2016.Design/methodology/approachThe authors employ the cross-sectional autoregressive distributed lags (CS-ARDL) approach.FindingsThe study’s investigation affirms the presence of an inverted U-shaped (nonlinear) relation between overall globalization and IQ indexes for the sample countries, which suggests no additional room for improvement in IQ. It also underpins the existence of an inverted-U-shaped (nonlinear) relation between political globalization and IQ. In contrast, economic and social globalizations have a U-shaped relation with IQ, implying more scope for improvement.Research limitations/implicationsThe findings have key policy implications. First, policy makers should consider a long-run approach for improving IQ and globalization over time. Second, quick reforms in the short run may not improve IQ.Practical implicationsThe results suggest that policy makers should approach the globalization process from a long-run perspective as well by designing appropriate strategies to provide a continuous but gradual increase in globalization so as to systematically monitor the threshold limits to IQ from improving globalizationOriginality/valueTo the best of the authors’ knowledge, this work is the first to empirically investigate the overall role of globalization in promoting IQ under the conditions of short-run heterogeneity and long-run homogeneity. The authors focus on the member countries of the OIC, many of which are ruled by authoritarian regimes and suffer from a poor domestic institutional setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
