旅游城镇化驱动乡村振兴的影响效应研究

旅游城镇化作为新型城镇化的一种典型模式,是新发展阶段实现乡村振兴的有效路径。以张家界武陵源区为例,紧扣旅游城镇化驱动乡村振兴的关键影响因素和传导路径,基于系统动力学方法对旅游城镇化驱动乡村振兴的影响效应进行仿真模拟。研究发现,旅游城镇化对乡村振兴的驱动是一个复杂的动态过程,需精准分析旅游城镇化作用乡村振兴的不同路径及其影响效应;武陵源区目前的自然发展模式虽能创造较好的经济增长效应,但会造成结构性失业、资源破坏和环境污染等问题;在5种仿真模式中,兼顾经济-社会-环境的协同发展路径是推进乡村振兴的最佳模式;旅游政策影响因子在不同仿真模式中均成为重要的政策因子,印证了武陵源区旅游发展在乡村振兴战略中的重要地位。实现旅游城镇化对乡村振兴的最佳驱动必须从经济增长、社会文化与生态优化三个层面联合发力,以系统化的协同发展路径促进乡村振兴。研究有助于进一步理解旅游城镇化与乡村振兴的多元内在关系,为我国乡村地区尤其是西部民族地区的乡村振兴提供借鉴。     

医药企业负面网络舆情演化及应对策略研究

探讨因媒体不当报道引发医药企业网络舆情危机的演变规律,为企业找寻适宜的对策,有助于提高医药企业危机应对能力。文章以“深圳康泰公司乙肝疫苗信任危机”为例,构建了医药企业负面网络舆情演化和响应策略的系统动力学模型,并采用Vensim PLE软件进行仿真。结果表明:医药企业负面网络舆情经过酝酿、爆发、衰退三个阶段,且呈现爆发时间短、热度高、负面情绪强的特点;医药企业应根据舆情演化阶段特征采取不同应对策略,三个阶段对应有效应急策略依次是提升舆情监测能力、端正担责态度、提高信息公开度和沟通能力、注意形象修复和注重人文关怀。其中,提高信息公开度和沟通能力对负面网络舆情热度的峰值均有明显的削弱效果,整体提升企业舆情应对能力是改善舆情、挽救医药行业信任危机的有力措施。     

Symbolic correlation integral

This paper aims to introduce the concept of symbolic correlation integral SC that is extensively used in many scientific fields. The new correlation integral SC avoids the noisy parameter 𝜀 of the classical correlation integral, defined by Grassberger and Procaccia (1983 Grassberger, P., Procaccia, I. (1983). Measuring the strangeness of strange attractors. Physica D: Nonlinear Phenomena 9(1–2):189–208.[Crossref], [Web of Science ®] , [Google Scholar]) and extensively used for constructing correlation-integral-based statistics, as in the BDS test. Once the free parameter 𝜀 disappears, it is possible to construct a nonparametric powerful test for independence that can also be used as a diagnostic tool for model selection. The symbolic correlation integral is also extended to deal with multivariate models, and a test for causality is proposed as an example of the theoretical power of the new concept. With extensive Monte Carlo simulations, the paper shows the good size and power performance of symbolic correlation-integral-based tests.     

Learning,signaling, and convincing: The role of experimentation in the business modeling process

This study examines experimentation in the business modeling process, unpacking three different roles of experimentation: learning, signaling, and convincing. Learning is an inherent role of experimentation, as managers typically experiment to engage with the environment and to obtain knowledge. This study uncovers another set of roles, which have a symbolic nature. These roles show that experimentation is not just a learning process, but also a strategic legitimation process, aimed at enacting the environment. Experimentation serves the purpose of signaling to potential customers and other stakeholders, and of convincing them to embrace the business model. Furthermore, this study shows that experimentation takes two forms—purposeful interactions and experimental projects—and that these forms can support the different roles of experimentation.     

Internal Migration and Urban Change in Poland

The paper investigates population change and migration over the period 1984–1994 for communes. There are important conclusions emerging from this study. The first is that we are watching now a profound change of population redistribution patterns in Poland. We observed that direct upwards hierarchical mobility has been markedly modified. The first modification is the substantial reduction of migration from rural to urban locations. There were important changes in the role of cities and towns. Largest cities, massive gainers of the seventies and eighties, have tended to lose population in the mid-nineties. It is likely that they lose population mainly to the neighbouring communes. We believe that a suburbanization process has been put into motion. Medium to large sized towns and cities, in the range between 50,000 and 500,000 as well as small, but not the smallest, towns attract substantial parts of the migration pool.     

人员流动对组织间隐性知识共享影响研究

促进组织间隐性知识共享是一个企业取得成功的关键.隐性知识和人与人之间传染病的传播途径非常相似,主要是通过人与人之间的直接接触进行传播的.文章受传染病动力学建模思想的启发,针对有人员相互流动的两个组织,并考虑员工的引入和离职,构建了两组织间的隐性知识传播动力学模型,给出区分实现组织间隐性知识共享与否的阈值,并对模型进行数值仿真以验证所得理论结果的正确性.从理论性定量研究的角度说明,在两组织间适当进行人员流动能有效促进组织间隐性知识共享,而如果人员流动不合理则会起到抑制作用.

群体动力论在高校学生群体性事件中的应用

高校学生群体性事件的发生给建立和谐校园和稳定社会带来了严峻的挑战。针对目前高校校园内频频发生的学生群体性事件,高校管理部门应高度地重视。本文从库尔特？勒温的群体动力理论出发,将高校学生群体看成一个相互影响的系统,从网络、学生主体同质性以及教育职能等方面来分析高校学生群体性事件发生的主要诱因,然后从群体性事件的预防着眼,探讨了有效预防高校学生群体性事件的措施,以期有效地控制高校学生群体性事件的发生。
