Model and experimental development for Business Data Science

While Data Science has become increasingly significant for business strategies, operations, performance, efficiency and prediction, there is little work on this to provide a detailed guideline. We have proposed a Business Data Science (BDS) model that focuses on the model and experimental development that allows different types of functions, processes and roles to work together collaboratively for efficiency and performance improvements. Details with examples have been illustrated to show that BDS model can be a robust model. Future directions have been discussed to ensure that business intelligence, security, analytics and research contributions to BDS can be achieved.     

基于北斗定位的治安巡防管理系统设计与实现

传统的治安巡防系统通过在巡更点设定巡更记录本方式进行管理,存在代签、补签等问题。基于北斗导航定位,设计一种突破传统模式的治安巡防管理系统,由移动智能终端和巡防客户端组成,融入电子地图纠偏处理技术和路径规划算法。仿真实验表明,该路径规划算法能合理规划巡防人员巡防路线,提高巡防人员工作效率。系统应用于南京市浦口区江浦街道社区治安管理,打破了传统“应对”式城市治理模式,有利于破解巡防难、管控难、矛盾点压降难等现代城市治理中存在的问题。     

Revisiting (and Revising?) Sports Boycotts: From Rugby against South Africa to Soccer in Israel

For the first time in nearly 30 years, 2013 saw increasing public awareness of calls for a comprehensive boycott of and sanctions on a state based on questions of an ‘entrenched system of racial discrimination’. The call to boycott South African sport emerged in the 1950s as the apartheid state was developing and refining its comprehensive and systematic legal form amid growing international pressure for decolonisation. This is a different social and political context than the call 50 years later by Palestinian civil society for boycott, divestment and sanctions (BDS) against Israel. This paper draws on analyses of international anti-apartheid movements' campaigns against sporting contact with South Africa and the BDS call for the isolation of the Israeli state to propose a theory of sports boycotts. It looks at the anti-apartheid campaigns to consider ways in which the BDS campaign has an impact on existing historical understandings of cultural boycotts as a tactical and strategic campaign tool.     

国内外煤炭价格的非线性特征研究

煤炭是全球基础性能源和战略资源,特别是在以煤炭为主要能源消费的我国,煤炭价格分析是我国经济发展研究中至关重要的问题之一.本文利用BDS 法和替代数据法对我国两种煤炭价格(秦皇岛大同优混(Q5800K)和山西优混(Q5500K))和国外煤炭价格(澳大利亚BJ动力煤现货价)进行了深入研究.研究表明,3种煤炭价格收益率序列不服从正态分布,存在长相关特征并具有非线性结构.国外煤炭价格的非线性特征较国内煤炭价格非线性要强,表明国际煤炭市场的影响因素比国内煤炭市场更加复杂,市场化程度更高.在替代数据法检验时发现在嵌入维数大于5时,上述价格原始数据和替代数据均有显著性差异,表明影响国内外煤炭价格的主要因素至少5个,说明可以建立5维非线性模型进行短期预测,为我国煤炭政策制定及煤炭行业科学发展提供理论指导.     

地质灾害系统演化特性的定量判定

以地质灾害系统为研究对象,通过其相空间维数、Lyapunov指数、BD S统计分析以及R/S分析等一系列手段和方法的研究,认为对于绝大多数地质灾害系统而言,系统的演化规律主要受确定性规律所控制,但在演化过程中也会受到外界因素的干扰和系统本身内部涨落的影响。
