快慢速自适应融合的安全中继选择

针对无线通信中的物理层信息安全问题，在无线安全协作网络中提出了一种基于快慢速链路自适应融合的安全中继选择方法。该方法根据移动速度选择链路自适应类型，根据干扰节点对安全容量的“正”或“负”效应使用或不使用干扰节点，基于安全容量最大化准则进行中继选择。在此基础上，对所提安全中继选择方法进行了性能分析，推导了中断概率表达式。中断概率的仿真曲线和理论曲线很吻合，验证了理论分析的正确性。同时，仿真结果显示，相对于采用单一快速链路自适应，基于所提中继选择方法的安全协作通信系统具有更低的误码率和更大的安全容量，在“正效应”条件下干扰节点有助于提升系统安全容量。

企业创建扁平化组织结构及其主要措施

目前国际上很多公司都在大刀阔斧地压缩管理层次，扩大管理幅度，通过组织扁平化提高竞争优势。我国已经有一些企业进行了组织结构创新，并且取得了很好的效果。但目前绝大部分企业，尤其是大型企业集团，企业组织基本上还属于金字塔型结构，必须作战略性的变革。我国企业要构建扁平化组织结构。必须突破传统文化和传统管理理论的束缚，必须分权与集权相结合，必须实行团队式管理，必须建立学习型组织，必须提高人员素质，必须加强计算机网络技术建设。     

Italian consumer awareness of layer hens' welfare standards: a cluster analysis

Animal welfare has assumed in recent years an increasing significance for European consumers, becoming part of the Community Agricultural Policy strategy that encourages farmers to achieve higher standards of animal welfare. Undoubtedly, the superior social sensitivity towards animal welfare has produced over time notable changes within European Union (EU) Policy. However, while EU legislation has progressively focused on granting animals better possibilities to express their behavioural repertoire, recent analysis shows that consumer knowledge of animal welfare compulsory standards is still quite limited. Drawing on the results of a direct survey on 300 Italian food shoppers, our research analyses consumer knowledge of the welfare standards of laying hens. Our findings highlight important market opportunities and policy implications. Our research shows that, although the majority of the sample expressed concern on hen husbandry systems, most of respondents were unaware of the current mandatory labelling system for eggs. Through cluster analysis three segments were found: the inactive consumer cluster, the conflicted consumer cluster and the ethically competent consumer cluster. This segmentation is especially valuable for producers of ‘animal‐friendly’ eggs to identify market opportunities and formulate appropriate marketing strategies.     

非均匀微带线电磁脉冲耦合特性分析

针对电磁脉冲与非均匀微带线的耦合问题,基于时域有限差分法和卷积完全匹配层 ,研究了不同弯曲和不同斜切角非均匀微带线的电磁脉冲耦合特性,并对耦合机理进行了讨 论。仿真结果表明：由于结构的非均匀性,微带线不同端口的耦合系数相差较大;电磁脉冲 入射方向对耦合系数具有重要影响,不同方向耦合系数相差约60 dB;微带线拐角斜切 对降低 电磁耦合效果不明显。所得结论对提高微带电路和电子系统抗强电磁脉冲打击能力具有重要 意义。     

Structural production layer decomposition: a new method to measure differences between MRIO databases for footprint assessments

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input–output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint. Using the carbon footprint of the EU-28 in 2011 as an example, we analyse the differences between EXIOBASE, Eora, GTAP and WIOD. Identical environmental data are used across all MRIO databases. In all model comparisons, variations in domestic blocks have a more significant impact on the carbon footprint than variations in trade blocks. The results provide a wealth of information for MRIO developers and are relevant for policy makers designing climate policy measures targeted to specific stages along product supply chains.
