巢湖是我国水污染防治的重点水体,但近年来一直处于较高的富营养化水平.以巢湖二级支流店埠河流域内的地表水和地下水为研究对象,测试不同水体水化学组成和氢氧同位素值,综合运用数理统计、Piper三线图、Gibbs图和离子比值等方法,分析其季节性和空间变化特征,探讨地表水和地下水的水化学特征和形成机制.结果表明,①大气降水是店埠河流域地表水和地下水的主要补给来源,地表水的蒸发分馏效应比地下水更显著.不同时期,地表水比地下水更富集氢氧稳定同位素.地表水和地下水中氢氧稳定同位素均呈季节性变化特征,丰水期相对富集,枯水期相对贫化.②店埠河流域地表水和地下水均为弱碱性水,地表水中各离子浓度明显小于地下水,地表水中阳离子以Ca^(2+)和Na^(+)为主,地下水中阳离子以Ca^(2+)为主,水体中的优势阴离子均为HCO_(3)^(-).地表水的水化学类型以HCO_(3)·Cl-Na·Ca型水为主,地下水以HCO_(3)-Na·Ca型水为主.③地表水和地下水主要水化学指标浓度具有一定的时空差异性.从丰水期到枯水期,地表水中TDS、K^(+)、Na^(+)、Ca^(2+)、Mg^(2+)、Cl^(-)和SO_(4)^(2-)浓度整体呈现上升趋势.地下水中Na^(+)、Ca^(2+)和Mg^(2+)浓度整体变化不大,略有增加趋势,Cl^(-)、SO_(4)^(2-)和NO_(3)^(-)浓度整体呈上升趋势.从上游到下游,地表水中主要水化学指标浓度呈现先减小后增大的趋势,NO_(3)^(-)浓度增幅最大.地下水在径流方向上主要水化学指标浓度整体变化不大,但呈现出排泄区大于补给区的规律.④水体水化学特征的形成主要受水-岩作用控制,同时还受到人为因素影响.水-岩作用主要为硅酸盐岩、盐岩和碳酸盐岩等矿物的风化溶解.污水处理厂污水、生活污水和粪肥等污染物已明显改变了局部水体的水化学特征.⑤与2016年相比,地表水中的NO_(3)^(-)浓度已有不同程度地减少,当地政府进行的氮污染控制工作已取得一定成效,但仍需在店埠河下游、部分支流(定光河和马桥河)和部分居民点加强对污水及粪肥的污染防控.

党和国家监督贯通协调机制,是权力监督与权利监督的功能互补和有机结合,是跳出历史周期率“两个答案”即党的自我革命和人民监督理论的制度成果。党和国家监督贯通协调机制总体架构由党的集中统一领导机制、党内监督主导机制以及纪检监察监督统筹机制来支撑。党的集中统一领导机制涵盖党对监督体系中的各个监督要素的全面领导,是构建党和国家监督体系的基本前提和根本保证。党内监督主导机制是监督体系中各类监督的方向引领和重要示范。纪检监察统筹机制的功能是:跟进和落实党内监督、保障和接受人大监督、指导和衔接行政监督、衔接和加强司法监督、保障和支持民主监督、接受和引导群众监督及舆论监督、整合和协调审计财会统计监督力量,使党和国家监督体系的制度效能得到充分发挥。

永嘉学派作为锐意事功的学术流派,以务实黜虚为治学特点,侧重经制之学,尤其注重探讨宋代社会经济制度。他们重视研究货币流通思想、专卖政策、财税政策和会计制衡作用等,批判两宋王朝对百姓肆意盘剥进而阻碍社会经济的发展,旨在不断完善国家的治理政策和措施。这充分体现出他们密切关注现实的经世旨趣。随着研究兴趣的不断拓展,永嘉学人愈发密切关注当时社会经济的发展,把对历史的借鉴继承与对现实的批判反思有机结合起来,将历史考察与现实探究并重,最终奠定了永嘉学派在两宋乃至中国古代学术史上的重要地位。

数字化转型是银行业高质量发展的必然选择,但也可能引发一系列不平等的现象。运用2010—2021年中国208家商业银行数据,从经营绩效的视角考察银行数字化转型的马太效应及其内在机理。结果表明,银行数字化转型与经营绩效之间先表现为数字化悖论,后表现为财务增进,整体呈U型关系。大、小银行数字化转型存在明显的马太效应,随着银行规模增大,数字化转型与经营绩效关系的U型曲线拐点左移,即相较于小银行,大银行实现财务增进所需的数字化转型程度更低。机制分析表明,银行数字化转型与经营成本和经营收入分别呈倒U型和U型关系,且曲线拐点随着银行规模增大向左移动,导致银行数字化转型对经营绩效具有非线性影响,且在大、小银行之间存在马太效应。进一步讨论发现,银行数字化转型的马太效应还体现在经营风险层面,相较于小银行,数字化转型更有利于大银行降低经营风险。因此,在加快推进银行数字化转型的同时,应着重缓解马太效应,充分释放数字化发展红利,提高金融服务实体经济质效。
