基于改进的DORATASK飞行签派员工作负荷评估

飞行签派员作为航空运行的重要人员,其工作负荷强度对航空公司效益有着重要影响.根据改进的DORATASK方法,对飞行签派员工作负荷进行研究,将签派员放行航班的过程细化为13个工作进程,应用层次分析法对不同天气情况下每项工作内容进行评估,从而得出各项工作的难度系数,最终实现对飞行签派员放行一架飞机所承受工作负荷的评估.     

航空公司飞行签派员工作负荷评估研究与应用

首先定义了飞行签派员工作负荷的含义,并对其工作内容等背景知识进行了介绍,提出了签派员工作负荷的分类方法;其次,结合相关领域研究成果,归纳其工作负荷影响因素,并依此为基础建立签派员工作负荷评估的理论模型,提出了评估工作负荷的具体方法和过程;最后,讨论该方法在航空公司签派人力配置等方面的应用。     

循证训练理念下签派员技能全生命周期全动模拟机融合训练研究

为了培养高素质签派员队伍,借鉴飞行员技能全生命周期管理（PLM）体系建设相关理论,结合试点开展的“飞行员-签派员”融合训练,梳理其实施的可行性和必要性,探索签派员整个职业生涯岗位胜任力提升的实施路径。基于循证训练（EBT）理念总结“飞行员-签派员”融合训练的保障机制,为优化签派员训练模式提供参考。     

签派运行风险系统脆弱性分析

签派运行是衡量航空安全水平极为重要的一环，其工作流程多、综合性强、出错率高。因此，签派员是否能对风险进行及时辨识并做出有效操作十分重要。为了探究此系统的脆弱性，文章通过文献调研和专家咨询法，基于脆弱性理论识别影响签派运行安全的指标，综合运用DEMATAL-ISM-ANP构建签派运行风险系统脆弱性模型，以期进行科学且准确的风险管控，提升航空公司安全管理水平。结果表明，需要加强培训力度、健全规章制度与提高签派员的岗位胜任力。     

签派放行中人因差错研究

对签派员人因差错进行定义并对其分类,然后结合签派放行工作中的实际情况并在美国海军提出的HFACS理论模型的基础上进行改进,提出针对签派员放行工作的HFACS人因差错模型。接着介绍了基于此模型的数据处理方法——灰色相关联理论法。将航空公司调研收集到的签派人误不安全事件的相关数据进行灰色关联度分析,得出各影响因素的排序。最后在该模型的基础上结合关联度排序提出减少签派人因差错的措施及对策。     

基于TOPSISI的空管运行单位安全能力分类评估研究

从空管一线运行单位的安全出发,考虑到航班量逐年递增以及各空管运行单位年飞行保障量存在较大地区性差异。为使各空管运行单位现有安全保障能力与其飞行保障量更好的匹配,将塔台、区域保障架次和跑道数量作为重要的属性来进行空管安全能力评估单位分类。运用已构建的评估指标体系,采用标准离差法-TOPSIS排序法,通过输出结果验证单位分类评估的合理性。     

基于层析分析法的运行控制中决策因素的研究

首先对航空公司运行控制中影响决策的因素进行分析,利用层次分析法构建了在航空公司运行控制过程中主要影响签派员决策的关联因素模型,将复杂的系统层次化,通过逐层比较各种关联因素的重要性来分析各因素的重要程度,通过算例验证及数据分析,提出的基于层次分析的运行控制辅助决策模型能为最终的决策提供定量的依据.     

基于二阶聚类的空域飞行冲突危险性分级评估

飞行冲突危险性评估是空中交通安全管理的重要组成部分,是提升空中交通系统运行安全性与效率的关键手段.以国内外现有飞行冲突评估体系为基础,重新构建动态化的飞行冲突评估体系.通过信息熵给体系中各指标赋权用以描述飞行冲突危险性的影响,并基于实际飞行冲突数据计算飞行冲突危险性时间序列,进而全面分析单个飞行冲突事件以及冲突所在空域的危险性演化过程.最终基于二阶聚类针对空域飞行冲突危险性展开分级评估,有效弥补直接累加对于空域飞行冲突信息的掩盖.

On the Major Transformation of the Asia-Pacific Regional Structure北大核心CSSCISSCI

Recent years have witnessedsignificant changes in the Asia-Pacific regionalstructure featuring the shift in power balance among related countries as well as adjust-ments in their respective regional strategies. So what is the prevailing trend in thistransformation and what kind of regional order will likely emerge in the future？ To an-swer these questions, the paper tries to explore the following dimensions： the evolvingregional context, shift in power balance and power conversion, geo-political and geo-e-conomic developments and interactions between them, and evolving regional order. Asthe study shows, the broadening of regional geographical scope, the rise in the numberof actors involved, as well as changesin the relations among them, have combined tocast a pluralistic and complex flavor to the regional structure. While the power balanceamong China, the United States and Japan shifts, and power conversion is also occur-ring. China and Japan are paying increasing attention to their security roles, whereasthe United States under the Obama administration laid more stress on expanding itsgeo-economic clout. In spite of the intensifying geopolitical competition among China,the United States and Japan in recent years, a Sino-US strategic compromise-whichholds the key to regional geopolitics-isother front, some kind of geo-economicmore likely to take place in the future. On thecooperation will probably emerge. In the longerterm, it will be the geo-economic trend thatwill prevail over the geopolitical trend inthe region. Finally, the future evolution of regional order wiI1 mainly follow the eco-nomic logic, accompanied by the dilutionof its hegemonic and hierarchical nature.Hence, a pluralistic and complex regional community will emerge.     

The German Hanse and Bergen – new perspectives on an old subject

Abstract

The Hanseatic League and her kontors (trading posts) were an integral part of the medieval trade system in Northern Europe. Hanse merchants dominated many markets in this region and managed to maintain a monopoly-like role in towns like Novgorod and Bergen for many centuries. Consequently, one focus of historical research about the Hanseatic League lay on the mechanisms that enabled the Hanse merchants to keep that strong of a position for such a long time.

This article is part of the discussion about this topic. Based on Lübeck merchants with business interest in the Norwegian town of Bergen, the so-called Bergenfahrers (Bergen travellers), it will give new insights into the Hansards' economical and social organization. The three main points are (a) the integration of the Bergen market in the Hanseatic trade network as an intermediary trading place on the vivid East–West route of Hanse trade; (b) the importance of the Bergenfahrers within the Hanse merchants' economical, social and political networks; and (c) the structure of the Bergenfahrers network patterns in the late Middle Ages.

In addition to new insights into the important role of Bergen and the Bergenfahrers within Lübeck's and the other Wendish Hanse towns' trading system, this articles provides further proof for the usefulness of the methods of Social Network Analysis in medieval economic research.     

Organization and incentives in the age of sail

The British Navy in the age of sail was the most successful bureaucracy of its time. Its organization and incentive structures differed importantly from contemporaneous private sailing ventures, but closely resembled those of today’s large corporations. To induce efficient effort, the navy used a hierarchical tournament, in which sailors competed for higher pay that came with promotions based on relative performance. Promotion probabilities, the option value of future promotions, and the higher effort required of men in higher ranks and on larger vessels, combined to yield a highly skewed pay structure.     

Financial Reporting and Trade Credit: Evidence from Mandatory IFRS Adoption*

We investigate the effect of mandatory IFRS adoption on trade credit. We document that firms in countries that adopt IFRS receive more trade credit from their suppliers, consistent with improved financial reporting quality and comparability playing a role in facilitating informal financing. This increase is larger for countries with a low level of societal trust, a poor pre‐IFRS‐adoption information environment, and stronger legal enforcement. These cross‐sectional results suggest that the conditions under which higher‐quality information is made publicly available affect suppliers' decisions to provide trade credit. This increase is also larger for firms with greater exposure to foreign markets, a finding that highlights the importance of more comparable international financial reporting standards in facilitating cross‐country trade credit. We also find that IFRS adoption has a stronger positive effect on trade credit for firms with greater liquidity needs. Finally, we find that firms in countries that adopt IFRS also extend more trade credit to their customers. Overall, our results support the notion that financial reporting can have a causal effect on trade credit.

文化传播中电视暴力对青少年侵犯行为的影响

伴随当代传媒产业的蓬勃发展,暴力也成为影视艺术基本的叙事类型及消费主义文化日趋盛行的现实语境。＂电视暴力＂是作为＂媒介暴力＂的一个子概念存在的;从文化传播看电视暴力,其覆盖面大,且易于接触;电视暴力对受众特别是青少年的影响巨大而深刻。要从制作者、传播者和观众三个方面的自律出发,建立适应我国国情的影视分级制。     

理性与先验的完美整合——论笛卡尔的"上帝"观

笛卡尔是西方近代主体性哲学的先驱,是近代唯理论学说的创始人,他使人们从中世纪宗教势力的禁锢中解放了出来.虽然"上帝"这个被人们视为理性最大敌人的概念在他的哲学中大量存在,但他极力证明上帝存在的最终目的却是为了证明理性的伟大;作为真理化身的上帝,归根到底是为他的理性主义服务的.
