Rankings (RKS) and Hexun are the two most widely used corporate social responsibility (CSR) ratings in research on CSR in China’s capital market. These scores are used as a proxy for CSR performance and disclosure quality. However, research is lacking on the validity of measuring CSR performance and disclosure quality, as well as the convergent validity between these scores. In this paper, a comparative and quantitative analysis was performed for the period 2010–2017, and the following results were obtained: (1) Based on a comparison of the rating methods, information sources, and other factors, RKS is more suitable for measuring the CSR disclosure quality, while Hexun is more suitable for measuring the CSR performance; (2) based on a Spearman correlation analysis, the convergent validity between these two scores is very low, particularly after 2013; and (3) the sub-indicator weights of the RKS system always maintain a high stability, whereas those of the Hexun system suffer from severe fluctuations starting in 2013.

Background: To investigate the relationship between RAS association domain family protein 1A (RASSF1A) promoter methylation and the clinical features, and the survival of ovarian cancer patients. Methods: A comprehensive literature search was conducted in the PubMed, Embase, EBSCO, and Cochrane Library databases. The overall ORs with their 95% CIs were calculated in this meta-analysis. Results: Finally 17 relevant publications with 1,108 ovarian cancer samples were available for the current meta-analysis. RASSF1A promoter methylation had a significantly higher level in ovarian cancer than in low malignant potential (LMP) tumors. No significant relationship was observed between RASSF1A promoter methylation and the clinicopathological characteristics in ovarian cancer. Two studies reported that RASSF1A promoter methylation was not correlated with the survival of patients with ovarian cancer. Conclusions: Our findings suggest that the use of RASSF1A promoter methylation could distinguish ovarian cancer and LMP tumors. ­RASSF1A promoter methylation may not be correlated with the clinical features and the survival of ovarian cancer patients. More studies with large sample sizes are essential in the future.

Résumé Vus de l’Ouest, les débats et événements politiques en Chine ne sont pas toujours faciles à déchiffrer. Au mois de mars 2012, la chute de Bo Xilai, le leader de la municipalité autonome de Chongqing (de près de 30 millions d’habitants), surprit moins que la découverte que Bo était le leader des « néomaoïstes » en Chine. En cet automne de l’année 2012, se tient le 18 e Congrès du Parti Communiste à Pékin. Même en interrogeant des gens bien informés, au cours des derniers mois, il était presque impossible d’obtenir ne serait-ce qu’une vague intuition de ce qui pouvait résulter de la réunion. Cette interview doit être comprise comme une vaste fresque des principaux courants actuels qui sous-tendent les débats actuels en Chine. Le thème central est l’anticapitalisme, car, de manière assez surprenante, ce thème définit encore l’axe central autour duquel gravitent les controverses.
