面对错综复杂和快速变化的商业环境,组织要想做出快速响应,领导者的有效倾听显得非常重要。通过文献综述发现,现有研究尚未对领导倾听的概念形成统一界定,且理论视角和研究层次较为单一,这不利于我们深入理解领导倾听的内涵及其多层次效应。事实上,作为一种领导行为,领导倾听不仅会对领导者自身产生影响,而且会给团队及其下属带来影响。因此,本研究基于二元互动情境,从沟通信息和支持员工两方面对领导倾听的内涵进行探索性研究,并从领导力效能的评价对象(领导者、团队、员工)出发,结合多层次、多理论、多研究方法的全景研究范式逐步揭示领导倾听对不同对象的不同效应、黑箱机制及边界条件。本研究不仅开拓了倾听研究的新思路和新视角,而且为企业增强领导倾听的积极效能提供了管理启示。

Cells are the fundamental units of biological systems and exhibit unique development trajectories and molecular features. Our exploration of how the genomes orchestrate the formation and maintenance of each cell, and control the cellular phenotypes of various organismsis, is both captivating and intricate. Since the inception of the first single-cell RNA technology, technologies related to single-cell sequencing have experienced rapid advancements in recent years. These technologies have expanded horizontally to include single-cell genome, epigenome,proteome, and metabolome, while vertically, they have progressed to integrate multiple omics data and incorporate additional information such as spatial sc RNA-seq and CRISPR screening. Single-cell omics represent a groundbreaking advancement in the biomedical field,offering profound insights into the understanding of complex diseases, including cancers. Here, we comprehensively summarize recent advances in single-cell omics technologies, with a specific focus on the methodology section. This overview aims to guide researchers in selecting appropriate methods for single-cell sequencing and related data analysis.

在理论机制分析的基础上,基于2005—2020年我国30个省份的面板数据,采用Super-SBM模型测度了区域工业绿色发展水平,进而采用空间计量模型等方法检验了环境分权对区域工业绿色发展的影响。研究发现:(1)在考虑空间溢出效应的前提下,环境分权对区域工业绿色发展具有显著的抑制作用,但空间影响程度较为有限。使用工具变量处理内生性问题后,上述核心结论依然成立。(2)环境行政分权、环境监察分权及环境监测分权对工业绿色发展在影响方向或强度上存在显著差异。(3)进一步分析表明,财政分权、地方政府竞争程度的提升,强化了环境分权对工业绿色发展的抑制作用。(4)相比于东部地区,环境分权及其细分指标在中部和西部地区的边际效应更强;相比于2005—2012年,2013—2020年环境分权及细分指标的边际效应有所减弱。因此,建议建立跨级环境治理协作机制,强化数据透明度和公信力,明确权责匹配原则以及在环保垂管体制下细化环境分权政策。

数字文博产品在吸引青年走进“云端”博物馆的同时,也带领他们走近中华优秀传统文化。为探索青年群体从数字博物馆的接触中生成传统文化认同,刻画其表征、影响因素与过程,论文以“云游敦煌”“数字故宫”等17个代表性数字博物馆为样本,以QQ空间中的大规模评论数据为基准材料,采用混合研究设计:第一阶段,利用扎根理论对相关评论内容进行质化研究;第二阶段,随机招募到全国4365个有效青年样本参加线上问卷调查。研究结果显示:数字博物馆接触是促成青年传统文化认同的有力途径。其中,数字博物馆文化情境中的文化展品与文化表征耦合构成吸引青年的基础条件,启动环节在于唤醒青年主体的具身联觉,加工环节在于激活个体内隐文化心理加工过程以形成更深层次的文化感知,最终青年传统文化认同生成或强化的表现主要呈现于认知认同、情感涌现和行为实践三个方面。此外,与原有文化印象的比较和集体文化记忆的勾连,作为调节因素共同影响着青年传统文化认同结果。

背景:富血小板纤维蛋白具有制备简单、制作费用低、安全性高等诸多优势,目前已被广泛应用于口腔颌面外科骨缺损修复研究中,但存在降解速度太快、生长因子释放时间短等问题。目的:将富血小板纤维蛋白负载于甲基丙烯酰化明胶水凝胶内,通过体内外实验分析其促成骨性能。方法:①抽取新西兰大白兔静脉血,制备富血小板纤维蛋白。分别制备含0,0.05,0.075,0.1 g富血小板纤维蛋白的甲基丙烯酰化明胶水凝胶,分别记为GelMA、GelMA/PRF-0.05、GelMA/PRF-0.075、GelMA/PRF-0.1,表征水凝胶的微观形貌与体外缓释性能。②将4种水凝胶分别与MC3T3-E1细胞共培养,以单独培养的细胞为对照,检测细胞增殖活性;成骨诱导后,检测细胞碱性磷酸酶活性、矿化能力、成骨相关基因(骨钙素、骨桥蛋白、RUNX2)mRNA与蛋白表达,ERK1/2-p38 MAPK通路蛋白mRNA与蛋白表达。③取15只新西兰大白兔。在每只兔颅骨部分别制备4个直径8 mm的全层骨缺损,其中1处缺损不植入任何材料(空白对照组),另3处缺损分别植入GelMA水凝胶、富血小板纤维蛋白、GelMA/PRF-0.1水凝胶。术后4,8,12周,进行骨缺损部位Micro-CT扫描与骨组织形态观察。结果与结论:①扫描电镜下可见4组水凝胶都具有蜂窝状的孔隙结构,并且随着水凝胶中富血小板纤维蛋白含量的增加,水凝胶的孔径轻微减小,但组间比较无明显差异;3组GelMA/PRF水凝胶均能以一定的速率释放转化生长因子β1与胰岛素样生长因子1,随着时间的延长,转化生长因子β1与胰岛素样生长因子1累计释放量显著增加。②CCK-8检测与活/死染色显示,3组GelMA/PRF水凝胶可促进MC3T3-E1细胞的增殖;碱性磷酸酶染色、茜素红染色及成骨基因检测结果显示,GelMA/PRF水凝胶可促进MC3T3-E1细胞的成骨分化,同时可抑制ERK1/2-p38 MAPK通路蛋白的表达,并且呈现富血小板纤维蛋白含量依赖性。③Micro-CT扫描显示,GelMA/PRF-0.1水凝胶组兔骨缺损处骨矿物质密度与骨体积分数均高于其他3组(P<0.05);苏木精-伊红染色显示,相较于其他3组,GelMA/PRF-0.1水凝胶组兔骨缺损处新骨形成更快、更成熟。④结果表明,GelMA/PRF水凝胶在体内外均具有良好的促成骨性能,该作用可能与抑制ERK1/2-p38 MAPK通路蛋白表达有关。
