文章选取2015—2021年528家A股上市制造业企业数据,实证检验了ESG表现对制造业企业创新的影响及企业异质性的调节效应,并进行了分位数回归,进一步考察了ESG表现对创新产出的作用机制。研究发现,ESG表现的提升对企业创新有显著的正向影响;对于规模较大、资产净利率较低和拥有独立ESG报告的企业,ESG表现对创新产出和技术人员密集度的提升作用更为明显。进一步研究表明,本身创新水平较低的企业提升ESG表现对创新产出的促进作用更大;较好的ESG表现通过降低代理成本和缓解融资约束两条途径增加了创新产出。

自1999 年举行首次领导人会晤以来,中日韩在内生需求、政治引领和外部危机的共同驱动下,逐渐形成“峰会-部长级-工作级” 三级合作模式,不断深化各领域合作,持续拓展在中日韩自贸区设想和“RCEp+”框架等多种路径下的合作。同时,中日韩合作的发展也面临严峻的现实困境,包括美国干扰牵制增强、合作收益预期受损、集体认同缺失等一系列问题。尽管如此,中日韩合作有深厚的民意基础和显著的政治意愿,仍存发展潜力。为更有效把握中日韩合作的回暖势头,三国应致力于深化沟通交流,调适相互认知;扩大共同利益,增强相互依赖;加强战略协作,实现机制对接。历史经验证明,三国相互影响、彼此互动, 是促进地区稳定与繁荣的核心变量;三国和平共处,合力促进地区经济发展、文化融合,符合三方国家利益与地区合作需求,也是东北亚地区合作共赢、构建和平与稳定东亚的前提条件。

background: The welding trade includes many industrial activities in both the formal and informal sectors. Workers in this professional environment do not have access to individual and collective means of protection adapted to the activity, which exposes them to the dust emitted during their activity and therefore contributes to increasing the risk of developing respiratory disorders in this population. Objective: Our study aimed to evaluate the ventilatory function of metal welders in the city of Dakar. Method: This was a comparative study based on the analysis of the spirometric parameters of metal welders working in the city of Dakar (Senegal) with those of a control group of the same kind, selected from the general population. Measurements of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (pEF) and maximum mid expiratory flow (MMEF) were measured. Results: A total of 75 men between the ages of 19 and 61 were recruited and divided into two groups (43 controls and 32 welders). The welding population had more frequent distal and central obstructions and pulmonary restriction compared to the control group. The metals most commonly used by welders were aluminum for welders who had an obstruction, while for those who had a restriction, iron was the most used metal. Signs of metal fever were frequently found in welders, especially those with ventilatory disorders. Conclusion: The prevalence of respiratory disorders observed is close to that observed in industrial environments, where exposure levels are the highest. The lack of personal protective equipment could also be a significant risk factor in the development of these disorders.

本文在对硅谷银行破产事件前因后果进行梳理的基础上,首次运用事件研究法将硅谷银行破产所引发声誉风险对A股上市银行的影响及其异质性进行识别和检验。研究发现,该影响确实存在且异质性明显。具体而言:中国国有大型银行所受到声誉风险竞争效应的影响远高于传染效应,投资者对其信心增强。与之相反,区域性农商行与城商行受到的负面冲击幅度最大也最为严重,呈现出显著的声誉风险传染效应。全国性股份制银行的表现介于二者之间。

Head and neck squamous cell carcinoma (HNSCC) is a prevalent and lethal solid tumor with a high mortality rate. Conventional cancertreatments, including surgery, radiotherapy, and chemotherapy, primarily target cancer cell eradication. However, uncontrolled proliferation and metabolic activities of these cells result in abnormalities in nutrient levels, hypoxia, and immunosuppression within the tumor microenvironment (TME). These factors constrain the efficacy of traditional treatments by promoting drug resistance, recurrence, and metastasis. Nanomaterials (NMs), such as nanozymes, can exhibit enzymatic activity similar to that of natural enzymes and offer a promising avenuefor the direct modification of the TME through catalytic oxidation-reduction processes. Moreover, they can serve as sensitizers or drug deliverycarriers, enhancing the efficacy of traditional treatment methods. Recently, NMs have garnered significant attention from oncologists. Thisreview begins with an overview of the composition and unique characteristics of the TME. Subsequently, we comprehensively exploredthe application of NMs in the treatment of HNSCC. Finally, we discuss the potential prospects and challenges associated with usingNMs in biomedical research.

针对作业车间调度问题,以最小化最大完工时间为优化目标,提出一种基于多工序精确联动邻域结构的混合进化算法。从理论上给出了关键块中工序无效移动的判定条件,据此设计了3对工序精确联动的邻域结构。为避免算法过早收敛,引入基于邻域惩罚的交叉父本匹配选择算子与基于动态惩罚阈值的种群更新策略。通过与其他先进算法在车间调度问题基准算例上进行对比实验,验证了所提算法的有效性与稳定性。
