We propose a new ensemble classification algorithm, named super random subspace ensemble (Super RaSE), to tackle the sparse classification problem. The proposed algorithm is motivated by the random subspace ensemble algorithm (RaSE). The RaSE method was shown to be a flexible framework that can...

Given the rapid development of China's new urbanization, cities with different locations and varying functional positioning, resource endowments, and development stages have insufficient scientific and applicable technical tools for implementing the United Nations Sustainable Development Goals...

Cities are key to countries' strategies for achieving the UN's sustainable development goals (SDGs). In China, evaluating cities' sustainable development (CSD) processes and abilities requires establishing an indicator library for cities' sustainable development (ILCSD). Based on the SDG...

As China continues to develop its ecological civilization, it is crucial to quantitatively assess the ecological value to understand its potential impact on regional sustainable development. While previous studies have highlighted the importance of ecological value, they have not fully reflected...

The purpose of this study is to deepen our understanding of government directors' impact on firm performance. This study strives to answer whether government directors have different effects on accounting- and market-based performance. To correct for the endogeneity of government directors...

Based on the risk hedging perspective, this paper examines the impact of directors' and officers' liability insurance (hereafter referred to as D&O liability insurance) on the pricing of corporate bonds. We find that the purchase of D&O liability insurance can effectively reduce corporate bond...

This study uses a novel dataset from 54 countries and regions to explore how exposure to climate change regulatory shocks influences firms' debt costs. The findings reveal that such exposure generally increases the cost of debt. However, this scenario is reversed for firms that find greater...

The crisis caused by the outbreak of COVID-19 revealed the global unpreparedness for handling the impact of a pandemic. In this paper, we present a first quarter chronicle of COVID-19 in Hubei China, Italy and Spain, particularly focusing on infection speed, death and fatality rates. By...

In this paper, we generate boundary value problems for ruin probabilities of surplus-dependent premium risk processes, under a renewal case scenario, Erlang (2) claim arrivals, and a hypoexponential claims scenario, Erlang (2) claim sizes. Applying the approximation theory of solutions of linear...

Trees play an important part in landscaping as well as thermal environment adjustment. This study selected a satellite city of Sichuan Province in China, Xindu, for field measurement about tree’s crown characteristics on their cooling performances on five sunny summer days during August 2019....
