传统人力资源管理主要关注具有正式雇佣关系的员工个体,但实践发现,曾在特定组织内工作但已解除雇佣关系的离职员工仍可能通过人际关系、信息交换等方式对原组织业务、品牌声誉产生积极影响,此类行为可概括为离职员工积极行为。收集知名网络论坛等公开二手资料,构建离职员工影响原组织积极行为的理论模型,通过深度访谈25名拥有离职经历的人员并对其进行开放式编码、主轴编码、选择性编码,在验证和深化模型的基础上,分别识别出5个主因素:关系建设与维系、个体因素、利益感知、原组织客观因素、行为边界条件,按作用程度将其划分为有促进作用的激励因素和仅能消除负面作用的保健因素,可为离职员工与组织关系研究提供有益补充。

The two-dimensional(2D)C3 N has emerged as a material with promising applications in high performance device owing to its intrinsic bandgap and tunable electronic properties.Although there are several reports about the bandgap tuning of C3 N via stacking or forming nanoribbon,bandgap modulation of bilayer C3 N nanoribbons(C3NNRS)with various edge structures is still far from well understood.Here,based on extensive first-principles calculations,we demonstrated the effective bandgap engineering of C3 N by cutting it into hydrogen passivated C3 NNRS and stacking them into bilayer heterostructures.It was found that armchair(AC)C3 NNRS with three types of edge structures are all semiconductors,while only zigzag(ZZ)C3NNRS with edges composed of both C and N atoms(ZZCN/CN)are semiconductors.The bandgaps of all semiconducting C3 NNRS are larger than that of C3 N nanosheet.More interestingly,AC-C3 NNRS with CN/CN edges(AC-CN/CN)possess direct bandgap while ZZ-CN/CN have indirect bandgap.Compared with the monolayer C3 NNR,the bandgaps of bilayer C3NNRS can be greatly modulated via different stacking orders and edge structures,varying from 0.43 eV for ZZ-CN/CN with AB’-stacking to 0.04 eV for AC-CN/CN with AA-stacking.Particularly,transition from direct to indirect bandgap was observed in the bilayer AC-CN/CN heterostructure with AA^stacking,and the indirect-to-direct transition was found in the bilayer ZZ-CN/CN with ABstacking.This work provides insights into the effective bandgap engineering of C3 N and offers a new opportunity for its applications in nano-electronics and optoelectronic devices.

Unlike previous studies that have primarily focused on the causes and processes, this research emphasizes the consequences of collective turnover. Starting from a literature review, we use event chains to explore the consequences of collective turnover. Based on the case study of the Qidian founders＇ collective turnover, we build a holistic theoretical framework to show the dynamics and continuity over time, influenced by the complexity of context. Our main conclusions are as follows：（1） collective turnover has a cascade effect, causing a series of secondary and derivative events, （2） collective turnover has both proximal and distal impacts on human capital flow, operational performance and financial performance, （3） whether or not a collective turnover has a positive or negative effect depends on the context factors. An event chain perspective that extends collective turnover theory and organizational behavior theory is used. We advocate for an integrate understanding of the consequences of collective tumover. In addition, this research will provide practical, instructive policies to intervene in collective turnover.

Nitrogen-doped graphene(NG)has attracted increasing attention because its properties are significantly different to pristine graphene,making it useful for various applications in physics,chemistry,biology,and materials science.However,the NGs that can currently be fabricated using most experimental methods always have low N concentrations and a mixture of N dopants,which limits the desirable physical and chemical properties.

Chemical vapor deposition(CVD)-grown graphene films on Cu foils,exhibiting fine scalability and high quality,are still suffering from the adverse impact of surface contamination,i.e.,amorphous carbon.Despite the recent successful preparation of superclean graphene through Cu-vapor-assisted reactions,the formation mechanism of amorphous carbon remains unclear,especially with regard to the functions of substrates.Herein,we have found that the crystallographic orientations of underlying metal substrates would determine the cleanness of graphene in such a way that slower diffusion of active carbon species on asformed graphene-Cu(100)surface is the key factor that suppresses the formation of contamination.The facile synthesis of clean graphene is achieved on the meter-sized Cu(100)that is transformed from the polycrystalline Cu foils.Furthermore,a clean surface of graphene on Cu(100)ensures the reduction of transfer-related polymer residues,and enhanced optical and electrical performance,which allows for versatile applications of graphene in biosensors,functioning as flexible transparent electrodes.This work would offer a promising material platform for the fundamental investigation and create new opportunities for the advanced applications of high-quality graphene films.

Zinc ion batteries are considered as potential energy storage devices due to their advantages of low-cost,high-safety,and high theoretical capacity.However,dendrite growth and chemical corrosion occurring on Zn anode limit their commercialization.These problems can be tackled through the optimization of the electrolyte.However,the screening of electrolyte additives using normal electrochemical methods is time-consuming and labor-intensive.Herein,a fast and simple method based on the digital holography is developed.It can realize the in situ monitoring of electrode/electrolyte interface and provide direct information concerning ion concentration evolution of the diffusion layer.It is effective and time-saving in estimating the homogeneity of the deposition layer and predicting the tendency of dendrite growth,thus able to value the applicability of electrolyte additives.The feasibility of this method is further validated by the forecast and evaluation of thioacetamide additive.Based on systematic characterization,it is proved that the introduction of thioacetamide can not only regulate the interficial ion flux to induce dendrite-free Zn deposition,but also construct adsorption molecule layers to inhibit side reactions of Zn anode.Being easy to operate,capable of in situ observation,and able to endure harsh conditions,digital holography method will be a promising approach for the interfacial investigation of other battery systems.

Graphene,which is the thinnest two-dimensional material in nature,has been extensively studied due to its exceptional mechanical,thermal,electronic,and magnetic properties,and because it has the potential to replace silicon in future electronics and spintronics applications.[1,2]Although pristine graphene is a semimetal,a medium-sized band gap can be opened by cutting into narrow graphene nanoribbons (GNRs)

采用基于密度泛函理论(Density Functional Theory,DFT)的第一性原理计算,研究了堆垛方式、层数及外加电场对C_(3)N的带隙调控.考察了AA-1型、AA-2型、AB-1型和AB-2型这4种堆垛结构,计算表明,AB-2型堆垛结构能量最为有利.通过HSE06杂化泛函对带隙进行了精确计算,发现AA型堆垛与AB型堆垛的双层C_(3)N存在较大的带隙差异,AA型堆垛结构的带隙要明显小于AB型堆垛结构.此外,还发现C_(3)N的带隙可由单层的1.21 eV调控到体相的0.69 eV;通过施加外加垂直电场,可以将具有AB-2型堆垛结构的双层、三层和四层C_(3)N半导体调控为趋于零带隙的金属.
