Reputation mechanism is introduced and Bayesian approach is based on, in which government supervision as well as consumer purchasing behavior is taken as crucial factors to impact on the food quality security. As to the proposed quantitative indicators, government supervision includes exposure rate, fine and etc.;at the same time, consumer purchasing behavior includes consumer’s WTP for security food and consumer expectations to food safety. Taking China’s dairy industry as an example, it makes simulation by Netlog. The results show that consumer purchasing behavior alone has little effect on the dairy companies’ decision-making to be honest or counterfeiting enterprises. However, combination government supervision with purchasing behavior has great impact, and plays very good effects on food safety.展开更多

The changes in economic system and economic structure decide the changes of fiscal function and fiscal structure, which results in the changes in intergovernmental distribution form and local government behavior. This paper takes a look at the stages of China's fiscal reform process and the impacts on local government behavior, and tries to find measures for perfecting the fiscal system reform to optimize local government behavior and guarantee a healthy national economy.展开更多

Implementation of building energy efficiency of government regulation covers three aspects of construction and involves relevant participators, so the paper analyzes interests and roles of the related subjects in building energy saving, explore the motivations and its conversion mechanism of each player, and dissect the game relationship of associated earnings of developers' and consumers' behaviors selection under government control. Finally, the paper proposes basic requirements of building incentive policies for related subjects under government control to regulate the main behaviors of subjects in building energy efficient buildings and achieve energy efficiency goals and balance of all parties' benefits.展开更多

Methods: Forty-six AD patients aged 49 - 76 years were recruited for the study. Neurofeedback regulation was conducted using a BCI game designed to modulate EEG rhythms. Cognitive function was assessed using MMSE, MoCA, and ADAS-cog scales before and after a 10-day training period. EEG measurements were taken to evaluate changes in brain activity complexity. Statistical analyses were performed using SPSS25.0 software to compare pre- and post-training scores. Results: Post-intervention results showed significant improvement in the cognitive function of AD patients. The total scores of MMSE, MoCA, and ADAS-cog scales increased significantly (P < 0.01). Notable improvements were observed in memory, language, and attention domains. EEG complexity in the left frontal area also showed a significant increase (P < 0.05). Additionally, the disruptive behaviors of patients were significantly reduced, improving their overall quality of life. Conclusions: Neurofeedback therapy based on BCI games is a promising intervention for enhancing cognitive functions and reducing disruptive behaviors in AD patients. This innovative approach demonstrates significant potential for clinical application, providing a non-invasive method to improve patient outcomes. Further studies with larger sample sizes and long-term follow-ups are recommended to validate these findings and explore the specific effects of NFB training on different cognitive impairment levels.展开更多

Innovation can vastly improve the welfare of consumers, investors, firms and the economy. However, there is relatively limited evidence of how corporate governance affects corporate innovation. In this study, the author theoretically demonstrates how internal governance mechanisms interact to affect innovation, such as internal control, monitoring and compensation contracts. Governance mechanisms are determined by firm characteristics. The "best" governance structures that can be adopted universally do not exist. However, innovative firms often share similar characteristics, and they adopt similar governance mechanisms to facilitate innovation. The ultimate purpose of such internal governance mechanism that facilitates innovation is to prevent managers' myopia, and this paper concludes 5 different roles in internal governance mechanism that facilitate corporate innovation behavior.展开更多
