Research on the Relationship between Inaction Regret，Upward counterfactual Thinking and Repurchase Intention——Based on the Moderating Effect of Product Attitude and Regulatory Focus

生活中经常会有让自己后悔的事，不管是做了之后后悔还是没有做而后悔，在当今信息膨胀和压力陡增的社会，由于对资讯关注不够或精力过于分散，往往会错过很多好的机会，进而产生不行动后悔。目前，在营销学领域，无论是学术界还是企业实践对不行动后悔的关注都不够，对不行动后悔的产生机制和影响机制缺乏系统研究，企业也往往忽视了产生过不行动后悔情绪的消费者。因此，本文阅读和整理了大量文献，构建了从上行反事实思维到不行动后悔再到消费者再购意愿的主框架，试图弄清楚消费者错过第一次购买机会之后，不行动后悔是怎样产生的，以及消费者第二次面对相同购买机会时，不行动后悔对其再次购买意愿会产生什么样的作用。 本研究以消费者的不...There are always a lot of regretting things whether they are done or not. With the information exposing and pressure increased sharply, we are easy to generate regret because we pay not enough attention to information or scatter our energy greatly so that many good chances are missed. At present, in the field of marketing, both academic and business practice give little emphases on regret, which i...学位：管理学硕士院系专业：管理学院_市场营销学学号：1762012115120

A Study on Switching Cost and the User's Reuse Intention

大量管理研究证明用户满意度对其使用意愿和行为有重大作用,然而管理实践表明满意度对用户重复使用意愿的影响力趋于下降,而转换成本的作用日渐显现。本文采用问卷调查的研究方法,选取调查了337位即时通讯软件用户,并使用SPSS17.0和AMOA18.0对数据进行结构方程分析。结果表明相关经验和在线关怀的作用得到了全面验证,转换成本的影响因素对其影响的效果存在显著差异,且不同的转换成本类型对用户重复使用意愿的作用不同,程序转换成本和关系转换成本的作用显著。A large number of studies have shown users' satisfaction degree has a significant role on their use intentions and behaviors,while management practices reveal the impact of the satisfaction on the reuse intention tends to decline and the role of switching costs increasingly grow.This paper uses the survey research methods to survey the sample of 337 users of the instant messaging software(IMS) industry and analyzes the data using structural equation model by means of SPSS17 and AMOA18.0.The findings show that the effects of relative experience and online care have been fully validated,the influence factors of switching costs have significant difference in influence effect,and different types of switching costs plays varying roles in reuse intention,of which procedural switching costs and relational switching costs is significant.教育部人文社会科学研究规划基金项目;项目编号:11YJA63005

An Empirical Study on the Relationship between Ethical Predispositions and Charitable Behavior:Based on the Moderating Effect of Moral Identity

关于企业慈善捐赠问题学术界已经有了大量的研究成果,但关于个人慈善捐赠行为的研究则鲜有人问津。本文就道德认同(内在化和表征化)对道德倾向(功利导向和义务导向)与个人慈善捐赠行为关系的调节作用进行了理论和实证分析。本文利用对到厦门旅游的游客及厦门高校的学生进行问卷调查回收的453份样本数据,通过结构方程模型进行分析,研究结果表明,功利导向和义务导向分别会抑制和增加个人的慈善捐赠行为。除此之外,表征化弱化了功利导向与慈善捐赠行为之间的负向关系,内在化和表征化则强化了义务导向与慈善捐赠行为的正向关系。There are a large number of researches on corporate philanthropy donations in the academia,but the researches on individual charitable behavior are rarely concerned.This paper theoretically and empirically analyzes the moderating role of moral identity(internalization and symbolization)on the relationship between ethical predispositions(utilitarianism and formalism orientation)and individual charitable behavior.Based on the 453 questionnaires collected from the survey of tourists in Xiamen and students from Xiamen colleges,it arrives at the conclusion by structural equation model analysis,utilitarianism and formalism orientation respectively inhabits and enhances individual charitable behavior.In addition,symbolization weakens the negative relationship between utilitarianism orientation and charitable behavior,and internalization and symbolization strengthen the positive relationship between formalism orientation and individual charitable behavior.教育部人文社会科学研究规划基金项目“组织结构变革中的路径依赖与路径突破研究”(批准号:11YJA630057

Micron-Thick Interlocked Carbon Nanotube Films with Excellent Impact Resistance via Micro-Ballistic Impact

The highest specific energy absorption (SEA) of interlocked micron-thickness carbon nanotube (IMCNT) films subjected to micro-ballistic impact is reported in this paper. The SEA of the IMCNT films ranges from 0.8 to 1.6 MJ kg(-1), the greatest value for micron-thickness films to date. The multiple deformation-induced dissipation channels at the nanoscale involving disorder-to-order transition, frictional sliding, and entanglement of CNT fibrils contribute to the ultra-high SEA of the IMCNT. Furthermore, an anomalous thickness dependency of the SEA is observed, that is, the SEA increases with increasing thickness, which should be ascribed to the exponential growth in nano-interface that further boosts the energy dissipation efficiency as the film thickness increases. The results indicate that the developed IMCNT overcomes the size-dependent impact resistance of traditional materials and demonstrates great potential as a bulletproof material for high-performance flexible armor

Dynamic Mechanical Properties of Several High-Performance Single Fibers

High-performance fiber-reinforced composites (FRCs) are widely used in bulletproof structures, in which the mechanical properties of the single fibers play a crucial role in ballistic resistance. In this paper, the quasi-static and dynamic mechanical properties of three commonly used fibers, single aramid III, polyimide (PI), and poly-p-phenylenebenzobisoxazole (PBO) fibers are measured by a small-scale tensile testing machine and mini-split Hopkinson tension bar (mini-SHTB), respectively. The results show that the PBO fiber is superior to the other two fibers in terms of strength and elongation. Both the PBO and aramid III fibers exhibit an obvious strain-rate strengthening effect, while the tensile strength of the PI fiber increases initially, then decreases with the increase in strain rate. In addition, the PBO and aramid III fibers show ductile-to-brittle transition with increasing strain rate, and the PI fiber possesses plasticity in the employed strain rate range. Under a high strain rate, a noticeable radial splitting and fibrillation is observed for the PBO fiber, which can explain the strain-rate strengthening effect. Moreover, the large dispersion of the strength at the same strain rate is observed for all the single fibers, and it increases with increasing strain rate, which can be ascribed to the defects in the fibers. Considering the effect of strain rate, only the PBO fiber follows the Weibull distribution, suggesting that the hypothesis of Weibull distribution for single fibers needs to be revisited

Nanoparticles produced by nanosecond pulse laser ablation of a metallic glass in water

In this paper, we perform a single nanosecond pulse laser ablation of a Zr-based metallic glass (Vitreloy 1) target in water. The violent ejection of high-temperature ablation matter is observed from the target by means of explosive boiling, which is accompanied by a formation of cavitation bubble. These ablation products entered the water include a rich variety of nanoparticles that can be classified into three different types: full amorphous, amorphous-crystalline composite, and polycrystalline. The amorphous nanoparticles have relatively smaller sizes and a uniform elemental distribution. The latter two types of nanoparticles exhibit a unique core-shell feature with an obvious compositional segregation. It is proposed that the diversity of the nanoparticles closely depends on the different pathways that they enter the water: directly before the bubble formation or via the bubble, in which the cooling rate and the glass-forming ability of ablation products are two competing factors

Experimental study on dynamic compressive behaviour of sandwich panel with shear thickening fluid filled pyramidal lattice truss core

The dynamic compressive behaviour of sandwich panels with shear thickening fluid (STF) filled pyramidal lattice truss cores at high strain rates is studied and compared with that of pure STF as well as the sandwich panels with empty and water filled pyramidal lattice truss cores by modified split Hopkinson pressure bar (SHPB) apparatus. The dynamic compressive strengths of the sandwich panels while filled with STF increase significantly when compared to the strengths of the sandwich panels with empty pyramidal lattice truss cores. It is interesting to note that the sandwich panel with the STF filled pyramidal lattice truss core shows "1 + 1 >> 2" dynamic energy absorption behaviour. The excellent energy absorption behaviour of the sandwich panel with STF filled truss core is interpreted by the transformation of deformation modes of core beams from non-symmetry to symmetry after filled with the STF through strong interaction between the buckling behaviour of pyramidal lattice truss core and the shear thickening behaviour of the filled STF material.

Temperature-dependent phase transformation of ice-1h under ultrafast uniaxial compression: A molecular dynamics simulation

The temperature and strain rate-dependent compressive behaviour of ice-1h was investigated through molecular dynamics simulations. The ice strength increased in response to a decrease in the initial temperature and an increase in the strain rate. Various deformation mechanisms depended on the ice's initial temperature. Solid-liquid phase transformation was more likely to at a relatively high temperature. However, solid-solid phase transformation and dislocation-like glide were observed at relatively low temperatures. Experimental observations on the strength versus strain rate relationship of ice could be interpreted based on a prior study by Wu and Prakash [1]

Nanoindentation of thin graphdiyne films: Experiments and molecular dynamics simulation

Graphdiyne possesses not only high strength but also excellent ductility, making it possible to be used in future high-performance protective structures. In this paper, the mechanical properties of graphdiyne were firstly measured by AFM experiments, and the failure behavior during low velocity perforation was also investigated by molecular dynamics (MD) simulations. Firstly, the elastic modulus was measured to be about 218.5 GPa by AFM experiments, which is about half of its ideal value due to various defects and the layer numbers of the synthesized graphdiyne film. Then, the nanoindentation processes of graphdiyne films were investigated by MD simulations, and the elastic modulus and strength were simulated to be about 489.04 GPa and 33.95 GPa, respectively. The failure behavior of the graphdiyne film was also studied in atomic level. Sequential broken of C C, C=C and C-C bonds and recombination of the broken bonds were observed to form a unique lathy crack. Furthermore, the effects of loading speed and indenter radius on the mechanical response of graphdiyne were investigated. A revised formula was developed for analyzing the mechanical properties of films in AFM experiments under various loading conditions. (C) 2018 Elsevier Ltd. All rights reserved
