Grey system theory has been widely used to forecast the economic data that are often highly nonlinear, irregular and non-stationary. Many models based on grey system theory could adapt to various economic time series data. However, some of these models didnt consider the impact of the model parameters, or only considered a simple change of the model parameters for the prediction. In this paper, we proposed the PSO based GM (1, 1) model using the optimized parameters in order to improve the forecasting accuracy. The experiment shows that PSO based GM (1, 1) gets much better forecasting accuracy compared with other widely used grey models on the actual chaotic economic data.

As COVID-19 struck worldwide, we were inspired by behavioral immune system theory and wondered whether there would be changes to public morality brought about by the pandemic. We tracked public reactions through posts on Chinese social media to analyze the dynamics of public moral motivation. Big data analysis shows that the impact of disaster upon moral motivation was context-sensitive. The level of the severity of the disaster played a leading role in variation of moral motivation. We found that disaster increased moral motivation only when the situation was severe, and such augmentation rapidly faded when the disaster was under control and recovery began. The sentiment of news shared during the pandemic played a regulating role, such that positive or encouraging news helped augment moral motivation only when the situation was severe. Finally, we found that the pandemic increased expressions of both agency and communion in a similar way to that of moral motivation.

The modern naval air defense of a fleet is a critical task dictating the equipment, the operation, and the management of the fleet. Military modelers consider that an improved weapon system in naval air defense (i.e. the AEGIS system) is the most critical enabler of defense at the engagement level. However, at the mission execution level, naval air defense is a cooperative endeavor of humans and weapon systems. The weapon system and the command and control (C2) structure of a fleet engage in the situation through human reporting-in and commands, as well as weapon deployments. Hence, this paper models the combination of the human and the weapon systems in naval air defense by covering the C2 hierarchy of the fleet, as well as the weapon systems of warships. After developing this mission-level model, we perform battle experiments with varying parameters in the human and weapon aspects. These battle experiments inform us of the impact of the changes in the human and the weapon systems. For example, the speed of incoming missiles is a critical parameter for a fleet’s survival; yet the decision-making speed is another outstanding parameter, which illustrates that there is more to improve than the weapon system when considering the mission level. This modeling and these experiments provide an example, suggesting a method of combining the human C2 and the weapon systems at the mission level in the military domain.

Linking local COVID-19 and population statistics to a U.S.-based survey we recently conducted, we study the spatial variation in the impact of COVID-19 on Americans’ attitudes toward China. The research strategy capitalizes on differential local COVID-19 incidence rates as varying dosages of the COVID-19 impact across local contexts in the U.S. Our results reveal negative yet heterogeneous effects of the ongoing COVID-19 pandemic on Americans’ attitudes toward China. We find that a greater local exposure to COVID-19 is associated with a lower level of trust in Chinese and a less favorable attitude toward China. These findings lend consistent support to behavioral immune system theory by bridging the literature on contextual variations in public opinion, with broader implications for U.S.–China relations.

Helping behaviors are considered critical for business and societal recovery in light of economic crises and natural disasters, including the COVID-19 pandemic that has both economic and health disaster elements. However, because the current COVID-19 pandemic has both of these elements, it is unclear how helping may be impacted. Economic crisis research suggests that such events are associated with less helping, whereas disaster research suggests that such events are associated with greater helping. We pair the event system theory (Morgeson, F. P., Mitchell, T. R., & Liu, D. (2015). Event system theory: An event-oriented approach to the organizational sciences. Academy of Management Review, 40(4), 515-537) with these two logics (economic downturn and disaster) to suggest that health and economic threats within the COVID-19 pandemic operate with potentially opposing forces on helping-related outcomes. To test these ideas at a macro-level, we examined internet search volume for recession, COVID-19, and interest in helping. At a micro-level, we examined the relationships between work- hour insecurity and perceived job-related COVID-19 risk—two salient COVID-19-related economic and health threats—and helping customers and coworkers. Consistent with economic crisis logic, macro-level concern about recession was negatively associated with interest in helping. Moreover, at the individual level, work-hour insecurity negatively predicted helping coworkers. Consistent with disaster logic, at the individual level, perceived job-related COVID-19 threat was positively associated with helping coworkers and negatively associated with helping customers. These findings suggest that the specific feature of the COVID-19 event system (economic versus health) and the target (organizational insiders versus outsiders) matter for shaping helping behavior. These findings have implications for helping during crises that involve economic and/or disaster elements.

Considering the change of the parameter related to the natural enemy population and the impact on the aphid populations in the fold catastrophe manifold, the singular system model of aphid ecosystems is proposed. Combining singular system theory with catastrophe theory, the corresponding dynamics behaviors and the existence conditions of the impasse points are given by using the qualitative analysis. The biological significance of the analytical results is also discussed. The controllers are designed to make the aphid populations stabilize the refuge level by releasing natural enemy. Some numerical simulations are carried out to prove the results.
