大型矿井动力操控员工安全心理参数探究

随着矿产资源不断向地层深部开采，矿井亦不断延伸，尤其是千米深井日渐增多，矿井动力提升速度和提升功能不断加快、增强，矿井数字化水平提高，对矿井动力操控员工的心理反应能力、注意能力、时空判断能力等一系列心理素质水平的要求不断增强。员工的反应准确性、注意集中和分配能力及情绪稳定性和人格状况是构成影响员工操控行为安全稳定的核心心理品质。探究矿井动力提升系统操控员工的各项安全心理阈限值及其安全心理参数标准，建立员工安全心理选拔准入制，是保障矿井人一机和谐安全运行的重要措施。     

Safety,security and peace tourism: The case of the DMZ area

It comes as no surprise that peace and tourism is an important topic today in tourism literature. Despite the strength of global tourist demand, many destinations, especially in the developing world, are facing fluctuations in tourist arrivals, due to unsafe political conditions. This study discusses the symbiosis between tourism and peace and its opposite, war, and the likely impacts of each condition on several tourist destinations. A turbulent security environment, caused by international and civil wars, coup d'etat and terrorist attacks has already demonstrated its negative impact on tourism development in many countries around the world (Taylor & Quayle, 1994). The aim of this study is to examine the relationship between safety, tranquility, peace, and successful tourism, using surveys completed by both international and domestic tourists. More specifically, it is about the effects of the absence of safety, security and peace on domestic and international tourism in the Korean demilitarized zone (DMZ) area. The general findings demonstrate that the subjects of the study view the implication of the existence of a peaceful environment on tourism favourably.     

浅谈建筑施工现场存在的安全问题与对策

随着社会经济的不断发展,建筑企业作为国民经济的支柱企业越来越得到人们的重视。建筑业是一个危险性高、安全事故频发的行业,并且在生产过程中,存在许多不可控的影响因素。施工中最大的问题便是安全问题,因为一旦出现安全事故不仅造成财产的损失、影响工期等,还会增加工程的成本甚至造成人员的伤亡。因此,安全管理是施工中必须要抓的重点问题。本文介绍了我国施工现场存在的安全管理问题,针对这些问题提出了相应的措施。     

Maritime tourism and terrorism: customer perceptions of the potential terrorist threat to cruise shipping

Maritime terrorism is a neglected area of research in tourism, particularly the use of scenario planning to understand potential threats to the cruise industry. Since the events of 9/11, terrorism, and the threat of terrorism, has become a major concern within the tourism industry. This article analyses tourist perception of perceived terrorist threats given that many ships are American owned. Using the scenario analysis presented by Greenberg, Chalk, Willis, Khilko, and Ortiz, this study suggests that an attack on a cruise ship is a distinct possibility. Indeed, 44% of respondents questioned perceived the possibility of a terrorist attack on a cruise ship to be likely despite the fact that safety and security is seen by the industry as a ‘hallmark’ of cruising. Differences in attitude among potential passengers revealed a high level of confidence in the cruise ship companies. This finding is particularly marked among more experienced cruise ship passengers. However, this did not necessarily preclude the possibility of security measures being improved. All passengers appeared generally resigned to the fact that risk is associated with travel in the twenty-first century and welcomed any efforts by cruise shipping companies to improve safety and security.

Strategic Asset Allocation for China＇s Foreign Reserves： A Copula Approach

In this paper, we study strategic asset allocation for China＇s foreign reserves using a risk- based approach. Four aspects of the risk management are investigated： an investment universe, dependence structure, allocation strategies under risk minimization and trade-off between risks and returns. A regime-switching copula model is developed to investigate the dynamic dependence between assets. One regime emphasizes a short-term safe asset and the other regime emphasizes a long-term safe asset. The optimal allocation is derived following two strategies： risk minimization and trade-off between risks and returns in utility maximization with disappointment avoidance, lf the central bank focuses solely on risk minimization, the asymmetries in the asset return dependence encourage the flight to safety. However, if higher risks are allowed in exchange for higher returns, even the exchange is very conservative, and the asymmetries would discourage the flight to safety. Therefore, we suggest that China should mitigate its flight to safety after 2008 and increase holdings of short-term bank deposits, long-term treasury bonds and euro bonds.     

碎麦提取物与昆虫信息素提取物混合诱捕多种储粮害虫效果研究

本文通过实验室模拟仓实验,研究了碎麦提取物与锈赤扁谷盗Cryptolestes ferrugineus、、锯谷盗Oryzaephilus surinamensis、赤拟谷盗Tribolium castaneum、玉米象Sitophilus zeamais、米象Sitophilus ory zae、谷蠹Rhyzopertha dominica信息素提取物混合诱捕储粮害虫效果的影响:本实验应用6种储粮害虫信息素提取物与碎麦提取物混合分别对多种储粮害虫进行诱捕,发现当多种害虫共存时,碎麦提取物与害虫信息素提取物混合对同种害虫的诱捕超过了单独使用碎麦提取物或同种害虫的信息素提取物的诱捕效果,而对于其它害虫的诱捕也都有较显著的增强作用。如碎麦提取物与米象信息素提取物混合除了对米象诱捕有增强作用外,对玉米象也有较好的诱捕作用;结果再次证明昆虫信息素结合食物引诱剂对监测害虫,特别是储粮害虫有较好的增效作用。
