Strong cosmic censorship for the massless Dirac field in the Reissner-Nordstrom-de Sitter spacetime

We present the Fermi story of strong cosmic censorship in the near-extremal Reissner-Nordstrom-de Sitter black hole. To this end, we first derive from scratch the criterion for the quasi-normal modes of Dirac field to violate strong cosmic censorship in such a background, which turns out to be exactly the same as those for Bose fields, although the involved energy momentum tensor is qualitatively different from that for Bose fields. Then to extract the low-lying quasi-normal modes by Prony method, we apply Crank-Nicolson method to evolve our Dirac field in the double null coordinates. As a result, it shows that for a fixed near-extremal black hole, strong cosmic censorship can be recovered by the $l=\frac{1}{2}$ black hole family mode once the charge of our Dirac field is greater than some critical value, which is increased as one approaches the extremal black hole.Comment: JHEP published versio

A First Exploration of China\u27s Antitrust Regulations: A Discussion of the Creative Function of the People\u27s Bank of China (Chinese)

The People\u27s Bank of China (PBC) has enhanced its macroeconomic status after spinning-off functions and restructuring, but faces two challenges from the monetary policy attenuation and the functional innovation. Against the background of the PBC President Zhou Xiao Chuan\u27s call for building financial ecology, beginning with China\u27s antitrust legislation, by demonstrating Chinese monetary enforcement and its transmission, this dissertation cross-analyzes economics and jurisprudence, and consequently concludes the necessity for PBC to withhold the Financial Antitrust

Impact of Perceived Value on Customer Satisfaction and Continuance Intention of Bicycle Sharing Service

Bicycle sharing service has been identified as one of the most significant applications in the sharing economy, yet few studies have explored its value stream from a customer perception perspective. Drawing upon value creation theoretical framework, this study proposes a research model to examine the impact mechanism of four value streams on customer satisfaction and continuance intention of bicycle sharing service. An empirical study was conducted and 293 valid data was collected from users of two leading bicycle-sharing platforms in China. Structural equation modeling technique was used to examine the research model. The empirical results suggest that emotional value is the most significant antecedent of customer satisfaction and continuance intention, followed by functional value and economic value. While environmental value has a positive but weaker influence on customer satisfaction. A post-hoc analysis further suggests that gender difference exists on the association between the four value streams and customer satisfaction
