We extend the recently proposed Kerr/CFT correspondence to examine the dual conformal field theory of four dimensional Kaluza-Klein black hole in Einstein-Maxwell-Dilaton theory. For the extremal Kaluza-Klein black hole, the central charge and temperature of the dual conformal field are calculated following the approach of Guica, Hartman, Song and Strominger. Meanwhile, we show that the microscopic entropy given by the Cardy formula agrees with Bekenstein-Hawking entropy of extremal Kaluza-Klein black hole. For the non-extremal case, by studying the near-region wave equation of a neutral massless scalar field, we investigate the hidden conformal symmetry of Kaluza-Klein black hole, and find the left and right temperatures of the dual conformal field theory.Furthermore, we find that the entropy of non-extremal Kaluza-Klein black hole is reproduced by Cardy formula.

The tourism industry in China has grown significantly over the last two decades. Most of the growth, however, is fueled by domestic tourism. As one of the biggest tourism markets in the world, U.S. tourists might be reluctant to travel to China due to reasons such as unfamiliarity, cultural differences, visa requirements, and long flights. Building on the Theory of Planned Behavior (TPB) with relevant constructs, this research proposes that building a strong destination image via eWOM may influence the attitude and intention of U.S. travelers to visit Beijing. More specifically, the current research aims to examine the impact of eWOM and destination image on travel intention of tourists. This study used a quantitative research method and online data collection was conducted through Qualtrics. A total of 413 valid responses from U.S. residents were collected. The statistical software SPSS 21.0 and Mplus 7.0 were used to analyze the data. Study results show a strong relationship between eWOM utilitarian function and eWOM credibility, and eWOM credibility has a significant influence on destination image. Although there was no direct impact of destination image on tourists’ future travel intention, destination image plays a mediating role between eWOM credibility and perceived behavioral control (and tourists’ attitudes as well). Finally, perceived behavioral control and tourists’ attitudes mediate the impact of destination image on travel intention.

This paper studies whether monetary transmission in China is asymmetric. While researchers found an asymmetric transmission in the U.S. and other economies, China offers a specific rationale for asymmetries: the presence of state-owned enterprises (SOEs) enjoying preferential access to financing. To study the consequences of SOEs for policy transmission, we differentiate between expansionary and restrictive policy shocks and argue that SOEs should suffer less from a policy tightening and benefit more from a policy easing. Based on sector-specific macroeconomic time series and a large firm-level data set, we provide evidence of a systematic and sizable asymmetry in the transmission of monetary policy shocks in China. The nature of the asymmetry is consistent with the notion of explicit or implicit government-guarantees of SOEs and has consequences for the adjustment of aggregate variables. In contrast to other central banks, the People's Bank of China seems to be able to "push on a string".
