基于时间序列模型在物流需求预测中的应用

本文采用时间序列模型进行物流需求预测，用实例从数据平稳性的判断，平稳化、标准化，建模，经模型的识别、定价、参数估计和检验，到预测及误差和置信区间的计算，详细地说明了时间序列模型在物流需求预测中是如何应用的。结果表明该ARMA模型能够较好地拟合并可获得较高的中短期预测精度。

盈利要求与投资决策

本讨论了公司盈利要求对经理投资决策行为的影响，并进一步将该结果与社会最优结果进行了比较分析。本研究结果表明，较高的盈利要求将导致经理选择高风险的投资项目，即使该投资项目的预期收益未必高于低风险投资项目。从社会福利最优角度来看，盈利要求对社会福利的影响取决于公司所面临的投资环境和投资项目性质。     

Creating narrative scenarios: Science fiction prototyping at Emerge

Scenarios are stories. In the diverse field of scenario planning, this is perhaps the single point of universal agreement. Yet if scenarios are stories, their literary qualities are often underdeveloped. Scenarios used in business and government frequently do not contain a relatable protagonist, move a plot toward resolution, or compellingly use metaphor, imagery, or other emotionally persuasive techniques of literature. In these cases, narrative is relegated to an adjunct role of summarizing the final results of the workshop. While this neglect of narrative may be reasonable in some contexts, the power of narrative should not be underestimated. Scenario planning methodologies can benefit from using diverse narrative techniques to craft compelling and infectious visions of the future. This article explores the relationship between science fiction and scenarios as story genres and investigates a creative story-telling technique, “Science Fiction Prototyping” (Johnson, 2011). While the method is promising, it is an ultimately problematic means to incorporating narrative into scenario planning.     

An integrated system for information security management with the unified framework

Information security management plays an essential role for drawing the roadmap of information security; thus, many theoretical methodologies and practical standards are brought into this domain. However, many standards and methodologies are too cumbersome to be adopted by an organization. Additionally, there is no unified framework to systematically handle the tedious tasks of information security management. This study’s primary goal is to design an integrated system for information security management (ISISM) that aims to use current methodologies and standards to solve the above-mentioned issues. Because business impact analysis and risk analysis are the most important areas within this domain, we carefully select the related methods and then integrate them into a unified framework, upon which the proposed ISISM depends. To achieve this outcome for this study, security requirement engineering is adopted, which enables the designed system to support system users in generating risk assessment reports with related information security policies.     

中外大学生英语硕士论文中四词词块的比较研究

本研究以中国学生和英语母语学生应用语言学硕士学位论文中的四词词块为调查对象,从结构和功能角度对比分析了中外大学生在英语学术写作中的词块使用情况。研究发现,与英语母语学生相比,中国学生使用了更多数量和更多种类的四词词块,更偏爱使用被动结构的词块,较少使用介词短语词块,但对"参与者主导的词块"的使用明显不足。     

Solvency Ⅱ与C-ROSS非寿险保险风险最低资本要求比较研究——基于中国60家财产保险公司的经验证据

本文以非寿险业务保险风险最低资本要求为考察对象,研究了欧盟Solvency Ⅱ与中国C-ROSS的差异,并利用中国保险市场60家财险公司的经验数据,对两者之间的差异进行了实证和模拟分析。研究结果表明,Solvency Ⅱ和C-ROSS对中国财险公司保险风险最低资本要求存在差异。对于拥有传统业务结构的财险公司,Solvency Ⅱ对保险风险最低资本要求更高,但是这种差距随着公司业务规模的缩小而减弱;对于以经营某些专业险种为主的财险公司,主营业务险种对两者差异具有决定性影响。本文的研究结论详细解释了Solvency Ⅱ与C-ROSS在非寿险保险风险最低资本计算上的异同,对C-ROSS下一步的修订工作提供了一定的支持与参考。
