Abstract: Abstract: According to the traffic accidents caused by the three types of entities between motor vehicle and non-motor vehicle or passerby in the common road, this paper presents an analysis and solution method based on Big data mining. The conditions and results of the induced traffic events are classified into relational tables, Rules is extracted from the table based on Apriori theory and using SQL routine. Through the analysis of the rules,that is obtained how to avoid traffic accidents between the entities.The depth and breadth of data is strengthened by the quasi Big data platform of the traffic department, The itemset is converted to relational tables and the attributes in the table can be given a relation definition, The relation degree can be used as the criterion for selecting the test set, The attribute reduction on the first level changes that the traditional Apriori algorithm treats each item in a itemset as an equivalent guiding to frequent judgment and make a choice , And the difference of principle reducts the search range causing enumeration and pruning, The difference in processing is that the routine provided by the DB system directly is executed rather than the frequent calling input and output of a DB.

Abstract: Terrorist attacks can occur anywhere. As the threat of terrorism develops, the China–Eurasia Expo held in Urumqi, China, is attracting fewer potential visitors. A nationwide survey of 2034 residents from 31 provinces/municipalities in China was conducted to examine the relation between the distance to respondents’ city of residence from Urumqi and their levels of concern for safety and security concerning the expo. The two were found to be positively related: the closer the respondents lived to ?rümqi, the less concerned they were with the safety and security of the expo. This is consistent with the ‘psychological typhoon eye’ effect, which states that people living closer to the centre of an unfortunate event (whether natural or man-made hazards) are less concerned with the event’s negative consequences. This effect appears to hold for terrorism. There are implications of this finding for international counter-terrorism practice, tourism, and research.

Abstract: "The Microblog behavioral data of typical disaster-stricken areas under the Impact of Typhoon Mangosteen (Guangdong) and non-disaster areas (Anhui) were selected to test the psychological typhoon eye effect from two dimensions of time and space with the method of big data analysis. The results show that there are differences of attention degree in the time dimension, but there is no "high-low-high" psychological typhoon eye pattern in the affected areas. Specifically, the attention of the affected areas after the transit of typhoon is higher than that before the transit of typhoon, while there is no significant difference of the attention of typhoon between the time periods before, during and after the transit. There is no significant difference between the disaster-stricken areas and the non-disaster areas in the dimension of spatial. Limitations of the study are mainly analyzed in order to provide relevant thinking and reference for future research.

Abstract:[目的/意义]“9.11”后世界各地恐怖主义活动呈现出增长趋势,且主要区域集中在“一带一路”沿线国家。在“一带一路”建设过程中,中国海外利益安全隐患巨大,需要我们采取相应措施干预,达到安全风险转移和消减的目的。[方法/过程]我们根据恐怖主义事件数据分析恐怖袭击的时空演变和分布特征,评估沿线国家的安全形势。通过分析国际警务协作模式、国家武装护卫模式、安保市场化模式,比较其成本效益。[结果/结论]安保市场化是具有成本效益的综合风险管理方法,可以以最低的资源消耗换取最低的预期损失,达到中国海外利益安全风险转移和消减的目的。而中国私营安保公司国际安保业务短板较多,我国应从法律规范、专业人才培养、安防产业培育、市场准入与监管方面开展工作,支持中国私营安保公司走出国门保障中国海外利益安全。
