The interference of the complex background and less information of the small targets are two major problems in vehicle attribute recognition. In this paper, two cascaded networks of vehicle attribute recognition are established to solve the two problems. For vehicle targets with normal size, the multitask cascaded convolution neural network MC-CNN-NT uses the improved Faster R-CNN as the location subnetwork. The vehicle targets in the complex background are extracted by the location subnetwork to the classification subnetwork CNN for the classification. (...) The implementation of this task decomposition strategy effectively eliminates the interference of the complex background in target detection. For vehicle targets with small size, the multitask cascaded convolution neural network MC-CNN-ST applies the network compression strategy and the multilayer feature fusion strategy to extract the feature maps. These strategies enrich the location information and semantic information of the feature maps. In order to optimize the nonlinear mapping ability and the hard-to-detect samples mining ability of the networks, the activation function and the loss function in the two cascaded networks are improved. The experimental results show that MC-CNN-NT for the normal targets and MC-CNN-ST for the small targets achieve the state-of-the-art performance compared with other attribute recognition networks.

In this paper, we employ the unique qualified foreign institutional investors (QFII) scheme in China to investigate whether and how the different religious beliefs in the areas where foreign institutional shareholders from are associated with the corporate social responsibility (CSR) performance of domestic firms. After controlling for other determinants, we find robust evidence that firms with QFII investors from areas with stronger religious beliefs have better CSR performance than those that do not have these beliefs'. This association is more pronounced (...) when a QFII has a shorter holding period, has a relatively large ownership in the firm, or is a more committed investor in China. The above moderating results show that the stock preference may be a channel through which religious QFIIs affect firms’ CSR performance. Our paper contributes to the growing body of literature on CSR and on the effects of investors’ religious beliefs. It also offers useful guidance to listed companies, institutional investors, regulators, and other stakeholders. (shrink)
