This study investigates the relationship between board composition and corporate social responsibility (CSR) performance. Specifically, we examine the impact of board composition (aspects like political experience, academic experience, overseas background, and gender diversity) on CSR performance. We test our hypotheses using data collected from 839 Chinese public firms during the period from 2008 to 2016. Applying generalized least squares regression, the study shows that the political experience, academic experience, and overseas background of the board members are positively related to the firm’s CSR performance. Moreover, we discuss the distinctive relationship between gender diversity and CSR performance in the context of Chinese culture. We extend the CSR literature by examining unique aspects of board composition in the Chinese context and offer fruitful implications for both scholars and practitioners.

Cardiopulmonary bypass (CPB) is often used in cardiothoracic surgery because its nonphysiological state causes pathophysiological changes in the body, causing multiorgan and multitissue damage to varying degrees. Postoperative cognitive dysfunction (POCD) is a common central nervous system complication after cardiac surgery. The etiology and mechanism of POCD are not clear. Neuroinflammation, brain mitochondrial dysfunction, cerebral embolism, ischemia, hypoxia, and other factors are related to the pathogenesis of POCD. There is a close relationship between CPB and POCD, as CPB can cause inflammation, hypoxia and reperfusion injury, and microemboli formation, all of which can trigger POCD. POCD increases medical costs, seriously affects patients' quality of life, and increases mortality. Currently, there is a lack of effective treatment methods for POCD. Commonly used methods include preoperative health management, reducing inflammation response during surgery, preventing microemboli formation, and implementing individualized rehabilitation programs after surgery. Strengthening preventive measures can minimize the occurrence of POCD and its adverse effects.

Sustainability has become a significant concern worldwide in recent decades. There seems to be implicit competition among firms for better sustainability performance. Like any other firm activity, sustainability undertakings require resources and their efficient use to achieve the desired performance. Firms may hesitate to undertake sustainability initiatives due to the underlying costs, leading to the question of how efficient they are in their sustainability practices. Relying on data from CSRHub and COMPUSTAT, we employed data envelopment analysis to evaluate the sustainability efficiency of 1141 large U.S. manufacturing firms from 2009 to 2018. We measured the sustainability efficiency of each firm relative to those on the efficient frontier for all the firms in our sample and also separately for each industry. The analysis results indicate that firms’ sustainability efficiency varies across years and industries. Furthermore, we show a quadratic relationship between sustainability performance and sustainability efficiency. This finding implies a process that begins with firms struggling to streamline their sustainability efforts and decreasing their efficiency as sustainability performance increases. Sustainability efficiency starts increasing only after a certain threshold is reached in sustainability performance. Our findings offer valuable insights for firms and stakeholders in their efforts to achieve desired levels of sustainability efficiency.
