ABSTRACT
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the infection of severe acute respiratory syndrome coronavirus 2, which is spreading all over the world and causing huge human and economic losses. For these reasons, we study the adaptive control problem of COVID-19 in consideration of media campaigns and treatment in this paper. Firstly, a novel compartment model is constructed by analysing the spread mechanism of COVID-19 and a nonlinear adaptive control problem is established. Then, using the estimation of parameters updated by adaptive laws, the controllers are designed to achieve the control goals. Finally, numerical examples are presented to illustrate the control capability to the outbreak of COVID-19.

The rapid spread and high death rates of the COVID-19 pandemic resulted in massive panic and anxiety all over the world. People rely heavily on media for information-seeking during the period of social isolation. This study aimed to explore the relationship between media exposure and anxiety, and highlighted the underlying mechanisms mediated by the media vicarious traumatization effect. A total of 1118 Chinese citizens participated in the online survey, who were from 30 provinces in mainland China. Results showed that all four types of media (official media, commercial media, social media, and overseas media) cause vicarious traumatization to their audiences to different degrees. It was also found that the impact of media exposure on anxiety was mediated by media vicarious traumatization: there were full mediation effects for commercial media exposure and overseas media exposure, while there were indirect-only mediation effects for official media exposure and social media exposure. Audiences staying in cities with a relatively severe pandemic were more susceptible to the vicarious traumatization caused by commercial media compared to those staying in Hubei. This study expanded the concept and application of vicarious traumatization to the mediated context, and the findings provided insightful advice to media practitioners in the face of major crisis.

PURPOSE OF REVIEW: This paper reviews the extant research on the effects of contact with terrorism media coverage on psychological outcomes in youth in the context of chronic threat and conflict in Israel. RECENT FINDINGS: The extant research is inconclusive with respect to the relationship between media contact and a variety of psychological outcomes in Israeli studies of youth exposed to ongoing threat and repeated terrorist attacks. Additional research is needed to examine potential differences in outcomes and the factors that influence youth coping and adaptation in an environment of chronic threat and extensive media coverage. Moreover, studies are needed to identify and evaluate potential parental, professional, and social strategies to enhance youth adjustment. Because political conflict in Israel is not likely to abate in the near future, the setting is ideal to conduct methodologically rigorous research including research using representative samples, prospective reporting, and longitudinal design.

Las organizaciones científico-profesionales deben desempeñar un papel mucho más activo en la prevención y control del tabaquismo del que han venido ejerciendo hasta la actualidad. Su actuación debe desarrollarse en tres ámbitos prioritarios: por un lado, en el del desarrollo de una política institucional propia en relación con la prevención y control de la epidemia tabáquica, implantando las recomendaciones nacionales e internacionales y ofreciendo una imagen ejemplar como les corresponde; por otro lado, promoviendo un mayor compromiso de los profesionales que agrupan, mediante la creación de un grupo de trabajo sobre tabaquismo, la evaluación periódica de los aspectos epidemiológicos del tabaquismo entre sus miembros, la promoción de actividades educativas sobre el tabaquismo, la puesta en práctica de programas de ayuda a la cesación entre sus miembros fumadores, la cooperación con los medios de comunicación y la promoción de la investigación científica sobre los diversos aspectos del tabaquismo, y finalmente dichas organizaciones deben contribuir decisivamente al desarrollo e implementación de una política nacional de prevención y control del tabaquismo, conjuntamente con las administraciones sanitarias y otras organizaciones, públicas y privadas, relacionadas con el problema (AU)
