The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on the world of sports due to periods of home quarantine, bans against public gatherings, travel restrictions, and a large number of postponed or canceled major sporting events. The literature hitherto is sparse, but early indications display signs of psychological impact on elite athletes due to the pandemic. However, beyond acute effects from lockdown and short-term interrupted athletic seasons, the postponed and still uncertain Olympic and Paralympic Games may represent a major career insecurity to many athletes world-wide, and may lead to severe changes to everyday lives and potentially prolonged psychological distress. Given the long-term perspective of these changes, researchers and stakeholders should address mental health and long-term job insecurity in athletes, including a specific focus on those with small financial margins, such as many female athletes, parasports athletes, athletes in smaller sports, and athletes from developing countries. Implications and the need for research are discussed.

The network of institutions that comprise the Olympic Movement include several whose authoritative scope now extends far beyond the mere staging of the Olympic and Paralympic Games to govern some important aspects of virtually all major regional and global competition and to foster the development of a comprehensive body of international sports law. The issues include nationality, which is the focus of this essay. More broadly, the proper resolution of nationality issues in the sports arena offers a limited model for reconciling tensions between national and international interests in the progressive development of international law.

In this paper, the effect of Fe3O4nanoparticle catalytic degradation brilliant blue X-BR dye was studied using spectrophotometric method. It was found that in the media of pH 0.65 HCl-NaAc buffer solution, 100 μmol/L H2O2, 0.7 g/L Fe3O4nanoparticle and the temperature 25°C, the degradation rate for reactive brilliant blue X-BR was over 93.5% in 20 min under the optimal conditions.
