The incident of 9/11 is said to be a watershed event in the history of international relations. After this ferocious incident Pakistan was forced to join the Global War on Terrorism in September 2001 and since then it has faced a lot of challenges. After joining this war, the security situation has become worse within few years, and military forces had to start several operations to fight and eliminate the menace of terrorism. The War on Terror (WOT) has greatly affected the economic growth, political and social situation of the country. This paper discusses the reasons behind the terrorism, the ways it has affected the national security, education and economy, and the steps for its elimination. The general conclusion made by the author is that Pakistan like other countries cannot cure this menace alone by the use of force. The government should adopt a complex and wide strategy focusing in priority on the factors that are responsible for igniting terrorism, and by solving the problems being faced by the poor masses of the country.

Abstract Thiophene derivatives have shown versatile pharmacological activities. The Suzuki reaction proved a convenient method for C–C bond formations in organic molecules. In the present research work novel derivatives of 2,5-dibromo-3-methylthiophene (3a–k and 3l–p) has been synthesized, via Suzuki coupling reaction in low to moderate yields. A wide range of functional groups were well tolerated in reaction. Density functional theory investigations on all synthesized derivatives (3a–3p) were performed in order to explore the structural properties. The pharmaceutical potential of synthesized compounds was investigated through various bioassays (antioxidant, antibacterial, antiurease activities). The compounds 3l, 3g, 3j, showed excellent antioxidant activity (86.0, 82.0, 81.3%), respectively by scavenging DPPH. Synthesized compounds showed promising antibacterial activity against tested strains. 3b, 3k, 3a, 3d and 3j showed potential antiurease activity with 67.7, 64.2, 58.8, 54.7 and 52.1% inhibition at 50 µg/ml. Results indicated that synthesized molecules could be a potential source of pharmaceutical agents.

This study emphasized the relationship between the Chinese companies' product market competition and organizational performance. This article explored the mediating effect of capital structure and the moderating impact of firm size in achieving better performance of Chinese companies. This study employed a sample of 2,502 Chinese firm observations and identified that market competition positively influenced firm performance. Additionally, capital structure partly mediated the relationship between product market competition and firm performance. Similarly, the present study also tested the moderating effect of firm size (both small and large) on the association between product market competition and firm performance. The results showed that moderating large businesses affects the nexus between product market competition and firm performance. Conversely, small firms' moderating role revealed a substantial adverse impact on the association between product market competition and firm performance. These findings contribute to the literature on the complex implications of market competition on business firms' performance. The results provide insightful and practical implications for future research directions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Mubeen, Han, Abbas, Raza and Bodian.)

The product market competition has become a global challenge for business organizations in the challenging and competitive market environment in the influx of the COVID-19 outbreak. The influence of products competition on organizational performance in developed economies has gained scholars' attention, and numerous studies explored its impacts on business profitability. The existing studies designate mixed findings between the linkage of CSR practices and Chinese business firms' healthier performance in emerging economies; however, the current global crisis due to the coronavirus has made product market completion fierce, which ultimately affects business firms' performance. This study focuses on this logical global challenge, investigates the rationale, and examines product-market completion impact on firms' performance operating in the Chinese markets. The study collected data from the annual reports of Chinese business organizations with A-share listing and registered with the database of China Stock Markets and Accounting Research (CSMAR). The study employed a Generalized Method of Moment technique and investigated the connection between product market competition and Chinese firm performance. The empirical analysis of this study highlights the conclusion that market competition positively and significantly affected business firms' performance. This study specified that product market competition play a dynamic and indispensable role in achieving healthier firm performance in the Chinese markets. This study provides valuable insights on practical implications and future research directions for the scholars to draw interesting results with new study models., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Liu, Qu, Wang, Abbas and Mubeen.)

The new identified virus COVID-19 has become one of the most contagious diseases in human history. The ongoing coronavirus has created severe threats to global mental health, which have resulted in crisis management challenges and international concerns related to health issues. As of September 9, 2021, there were over 223.4 million patients with COVID-19, including 4.6 million deaths and over 200 million recovered patients reported worldwide, which has made the COVID-19 outbreak one of the deadliest pandemics in human history. The aggressive public health implementations endorsed various precautionary safety and preventive strategies to suppress and minimize COVID-19 disease transmission. The second, third, and fourth waves of COVID-19 continue to pose global challenges to crisis management, as its evolution and implications are still unfolding. This study posits that examining the strategic ripostes and pandemic experiences sheds light on combatting this global emergency. This study recommends two model strategies that help reduce the adverse effects of the pandemic on the immune systems of the general population. This present paper recommends NPI interventions (non-pharmaceutical intervention) to combine various measures, such as the suppression strategy (lockdown and restrictions) and mitigation model to decrease the burden on health systems. The current COVID-19 health crisis has influenced all vital economic sectors and developed crisis management problems. The global supply of vaccines is still not sufficient to manage this global health emergency. In this crisis, NPIs are helpful to manage the spillover impacts of the pandemic. It articulates the prominence of resilience and economic and strategic agility to resume economic activities and resolve healthcare issues. This study primarily focuses on the role of social media to tackle challenges and crises posed by COVID-19 on economies, business activities, healthcare burdens, and government support for societies to resume businesses, and implications for global economic and healthcare provision disruptions. This study suggests that intervention strategies can control the rapid spread of COVID-19 with hands-on crisis management measures, and the healthcare system will resume normal conditions quickly. Global economies will revitalize scientific contributions and collaborations, including social science and business industries, through government support., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

This study focuses on exploring the relationship between chief executive officer (CEO) duality and firm performance. We focus on how the size and corporate social responsibility (CSR) of firms moderate this relationship. In terms of size, business organizations are of two types: small and large firms. This study uses datasets of listed Chinese business firms included in the China Stock Market and Accounting Research database. It employs a generalized method of moment's technique to explore the connection between CEO duality and the performance of Chinese business firms through double mediation effects. Our empirical analysis showed that CEO duality has a significant negative relationship with firm performance. We also explored the moderating effects of firm size (small and large) and CSR practices on the relationship between CEO duality and improved performance of Chinese firms. Large firms and CSR practices showed significant and positive moderating effects on the relationship between CEO duality and firm performance. Conversely, with CEO duality, small firms showed a negative moderating influence on firm performance. This inclusive model provides valuable insights into how the dual role of the CEO of a firm affected the performance of Chinese firms through the moderating role of CSR practices and firm size for better business performance. The study offers empirical and theoretical contributions to the corporate governance literature. This research framework might help researchers in designing robust strategies to evaluate the effects on firm performance. Researchers may gain helpful insights using this methodology., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Mubeen, Han, Abbas, Álvarez-Otero and Sial.)

Background: The coronavirus pandemic appeared as the worst global health disaster of the century. Since the advent of the Second world war-2, humankind has experienced the most challenging health emergencies. The novel respiratory disease (SARS-CoV-2) emerged in Wuhan at the end of December 2019., Aim: The study focuses on providing education through the educational system with a mode of delivery using digital solutions with a new paradigm method., Method: This research incorporates the statistical data related to the Pakistani Ministry of Health's coronavirus epidemic to draw the results., Results: WHO reported more than 51.949 million confirmed COVID-19 patients in more than 200 territories and countries. This epidemic caused more than 1.282 million deaths; however, more than 36.49 million people have recovered from the infection of the deadly disease COVID-19, as of November 11, 2020. The COVID-19 has put forward unique challenges in personal and social life spheres. The precautionary measures, including social distancing, called for abrupt closure of educational institutions, leaving the digital solutions as the primary mean of continuity in educational activities., Conclusion: The current review looks into the dynamics of embracing the change in the educational system, ranging from delivery mode to shifting to a new paradigm moving to digital solutions. This study looks into the challenges, issues, barriers, and success parameters of Pakistan's online learning management system. From the preparedness phase to the actual implementation of the learning system at higher education, the level is noteworthy. The private sector has provided higher, secondary, and primary levels; the private sector came forward to maintain learning continuity. The review suggests a way forward ahead for the educational system's continuity and sustainability in the coronavirus pandemic and educational institutions' crises., Competing Interests: The authors are well informed and declared no competing interests., (© 2020 The Authors.)

The study stipulates phases to observe the proposed mechanism in formulating the travel and leisure industry's recovery strategies. The present pandemic COVID-19 has resulted in global challenges, economic and healthcare crises, and posed spillover impacts on the global industries, including tourism and travel that the major contributor to the service industry worldwide. The tourism and leisure industry has faced the COVID-19 tourism impacts hardest-hit and lies among the most damaged global industries. The leisure and internal tourism indicated a steep decline amounting to 2.86 trillion US dollars, which quantified more than 50% revenue losses. In the first step, the study explores the consequences and settings of the COVID-19 pandemic and how innovation and change can contribute to the tourism industry's revival to the next normal. Thus, the study determines that tourism enterprises and scholars must consider and change the basic principles, main assumptions, and organizational situations related to research and practice framework through rebuilding and establishing the tourism sector. In the second step, the study discusses direct COVID-19 tourism impacts, attitudes, and practices in gaining the leisure industry's boom and recovery. In the third phase, the study proposes to observe the characteristics and COVID-19 tourism consequences on the travel and tourism research.

This present study primarily emphasizes to seek the COVID-19 adverse impacts posing health challenges and global economic crisis. The pandemic (COVID-19) continues to hit the global economies adversely. Pakistan is the 5th-most-populous nation, and recorded positive cases with the third-highest positivity ratio in South Asia, and 26th-highest deaths toll of 21,450 and 29th number of most COVID-19 positive cases with 933,750 worldwide, as of June 6, 2021. The first wave appeared at the end of May 2020, and mid of June reported its peak, which ended by mid-July 2020. Early November 2020 witnessed the second wave with low intensity reached the climax by mid-December. The COVID-19's third wave severely affected the country during mid-March 2021. It exhibited the highest positivity rate, around 20%. New positive patients and deaths toll commenced to skyrocket and reported peak by April 15, 2021. Then situation gradually improved with effective measures and restrictions. The pandemic coronavirus (COVID-19) has affected 220 territories, regions, and countries and resulted in more than 174.116 million infections, deaths, 3.75 million, and 157.157 million positive cases fully recovered from this infectious disease, as of June 7, 2021. The pandemic has caused a severe crisis of healthcare facilities and economic challenges worldwide. Pakistani economy reported GPD's negative growth (-0.05) for the first time over the last 60 years in 2020, which caused a massive financial crisis. The Government's relief package intervened to reduce public mental stress and improve the quality of their lives. IMF reported that Pakistan's GPD bounced back at 4% growth by June 2021. This article determines that economic instability and health burden happened in Pakistan for a longer time than financial disequilibrium that occurred globally. Pakistan encountered this crisis due to its feeble healthcare systems and fragile economy. This study explores adverse health issues and spillover consequences on the economic crisis in Pakistan with global implications. It recommends smart lockdown restrictions in most affected areas to reopen the economic cycle with strict preventive measures to minimize the COVD-19 adverse consequences., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Wang, Wang, Abbas, Duan and Mubeen.)
