Corporate social responsibility, firm reputation, and firm performance: The role of ethical leadership

Abstract: This study investigated the antecedents and outcomes of corporate social responsibility (CSR) and the moderating effects of ethical leadership. We collected two-wave, temporally lagged data from two sources (general and vice-general managers) in 199 tourism firms (hotels and travel agencies) in southeast China. We have two major findings. First, ethical leadership moderated its own indirect effect on firm reputation via CSR. It had an indirect and positive effect on firm reputation through CSR when ethical leadership was strong but not when it was weak. Second, ethical leadership also moderated the indirect effect of CSR on firm performance via firm reputation. There was an indirect and positive effect of CSR when ethical leadership was strong but not when ethical leadership was weak. This study highlights the role of ethical leadership in linking the antecedents and outcomes of CSR, and provides support for the stakeholder theory.

Degree mixing in multilayer networks impedes the evolution of cooperation.

Abstract: Traditionally, the evolution of cooperation has been studied on single, isolated networks. Yet a player, especially in human societies, will typically be a member of many different networks, and those networks will play different roles in the evolutionary process. Multilayer networks are therefore rapidly gaining on popularity as the more apt description of a networked society. With this motivation, we here consider two-layer scale-free networks with all possible combinations of degree mixing, wherein one network layer is used for the accumulation of payoffs and the other is used for strategy updating. We find that breaking the symmetry through assortative mixing in one layer and/or disassortative mixing in the other layer, as well as preserving the symmetry by means of assortative mixing in both layers, impedes the evolution of cooperation. We use degree-dependent distributions of strategies and cluster-size analysis to explain these results, which highlight the importance of hubs and the preservation of symmetry between multilayer networks for the successful resolution of social dilemmas.

Multi-Adversarial Discriminative Deep Domain Generalization for Face Presentation Attack Detection

Abstract: Face presentation attacks have become an increasingly critical issue in the face recognition community. Many face anti-spoofing methods have been proposed, but they cannot generalize well on "unseen" attacks. This work focuses on improving the generalization ability of face anti-spoofing methods from the perspective of the domain generalization. We propose to learn a generalized feature space via a novel multi-adversarial discriminative deep domain generalization framework. In this framework, a multi-adversarial deep domain generalization is performed under a dual-force triplet-mining constraint. This ensures that the learned feature space is discriminative and shared by multiple source domains, and thus is more generalized to new face presentation attacks. An auxiliary face depth supervision is incorporated to further enhance the generalization ability. Extensive experiments on four public datasets validate the effectiveness of the proposed method.

A Near-Infrared-Fluorescent Chemodosimeter for Mercuric Ion Based on an Expanded Porphyrin†

Abstract: An expanded porphyrin [26]hexaphyrin(1.1.1.1.1.1) was exploited as a fluorescent chemodosimeter for Ag + ions with high sensitivity and selectivity via near-infrared luminescence above 900 nm, a region that is free from optical interference in the visible wavelength range induced by the commonly used matrix and other organic compounds. The association constant for the Ag + –porphyrin complexation was evaluated by spectroscopic titration method to be 7.24 10 10 M 1 .

The role of traditional Chinese herbal medicines in cancer therapy--from TCM theory to mechanistic insights.

Abstract: Traditional Chinese medicine-based herbal medicines have gained increasing acceptance worldwide in recent years and are being pursued by pharmaceutical companies as rich resources for drug discovery. For many years, traditional Chinese medicines (TCM) have been applied for the treatment of cancers in China and beyond. Herbal medicines are generally low in cost, plentiful, and show very little toxicity or side effects in clinical practice. However, despite the vast interest and ever-increasing demand, the absence of strong evidence-based research and the lack of standardization of the herbal products are the main obstacles toward the globalization of TCM. In recent years, TCM research has greatly accelerated with the advancement of analytical technologies and methodologies. This review of TCM specifically used in the treatment of cancer is divided into two parts. Part one provides an overview of the philosophy, approaches and progress in TCM-based cancer therapy. Part two summarizes the current understanding of how TCM-derived compounds function as anticancer drugs.
