The study covers the first 6 months of the coronavirus disease 2019 (COVID-19) epidemics in 56 African countries (February 2020-August 2020). It links epidemiological parameters (incidence, case fatality) with demographic parameters (population density, urbanization, population concentration, fertility, mortality, and age structure), with economic parameters (gross domestic product [GDP] per capita, air transport), and with public health parameters (medical density). Epidemiological data are cases and deaths reported to the World Health Organization, and other variables come from databases of the United Nations agencies. Results show that COVID-19 spread fairly rapidly in Africa, although slower than in the rest of the world: In 3 months, all countries were affected, and in 6 months, approximately 1.1 million people (0.1% of the population) were diagnosed positive for COVID-19. The dynamics of the epidemic were fairly regular between April and July, with a net reproduction rate R0 = 1.35, but tended to slow down afterward, when R0 fell below 1.0 at the end of July. Differences in incidence were very large between countries and were correlated primarily with population density and urbanization, and to a lesser extent, with GDP per capita and population age structure. Differences in case fatality were smaller and correlated primarily with mortality level. Overall, Africa appeared very heterogeneous, with some countries severely affected while others very little.

This study was designed to investigate the effects of the Olympic Winter Games PyeongChang 2018 on South Koreans’ and Americans’ perceptions of the “Korean Wave,” or Hallyu. To achieve this purpose, a survey that included questions about the awareness of Hallyu among South Koreans and Americans was conducted before and after the Olympics. The results show that the Olympics positively influenced Hallyu and that the effect was greater for Koreans than for Americans. After watching the Olympics, Koreans had a greater sense of cultural soft power and their perception of Hallyu’s influence on the United States than before they watched the Olympics. However, for American participants, enduring involvement with Hallyu was the only factor that reflected a positive influence. This study demonstrates the relationship between international mega-sport events and a host country’s perceived cultural values.

This study aimed to compare internet use among African American older adults by gender and age group and investigate correlates of internet use by gender and age group. A total of 1117 African American older adults aged over 50 from the 2016 Wave of the Health Retirement Study were included in the study. Sequential ordinal logistic regressions were conducted to investigate correlates of internet use among older African Americans by gender and age group. Significant gender and age differences were identified in internet use frequency. Gender differences on correlates were revealed: being old-old and limitations on activities of daily living were only associated with decreased odds of more frequent internet use among women. In addition, higher depression was only associated with reduced odds of more frequent internet use among men. Age differences on correlates indicated that education and cognition were the only two significant factors pertinent to internet use among the old-old. By contrast, for young-old adults, retirement, poverty, education, cognition, and depression were also predictive. Practitioners should consider these gender and age differences when promoting internet use among older African Americans. The results presented in this study might also inform the design of future gender- and age-tailored interventions.
