Initiated under the Presidency of Xi Jinping in 2013, the Belt and Road Initiative (BRI) is still a young, yet a fast-developing and most ambitious regionalist project. Despite BRI's great potential to shape international trade and - more broadly - international relations amongst participating...

Policies and interventions involving the built environment have become a promising opportunity for the promotion of walking as a sustainable transportation mode. Among voluminous literature, few studies were found that examined the association between the built environment and walking among the...

The purpose of this paper is to explore the joint work of two mechanisms that might constrain autocratic rulers: the threat of a coup by the political elite and of a revolution by the citizens. Our results will help explain a well-established and crucial fact, that is, that autocracies are far...

Wavelets are applied to detect the jumps in a heteroscedastic autoregressive model. The empirical wavelet coefficients are defined respectively for the conditional mean and the conditional variance of the model. It is shown that the wavelet coefficients exhibit high peaks near the jump points,...

Wavelets are applied to identify the time delay and thresholds in open-loop threshold autoregressive models. Based on Truong and Stone's lemma, the empirical wavelet coefficients of the data are defined. The time delay and thresholds are detected and then estimated by checking the variation of...
