企业规划与信息系统规划战略一致性实证研究

以战略匹配模型(SAM) 及其在企业活动中的过程模型为研究对象,探讨了企业规划(BP) 和信息系统规划( ISP) 战略一致性程度与企业内外环境、企业所采取的竞争战略方向、ISP 的战 略地位以及IT 对企业业绩的贡献等因素间的关系,并运用中国企业数据进行了实证分析. 结 果表明,企业高层的战略规划意识以及利用IT 整合企业资源的能力与BP2ISP 战略一致性程度 和企业业绩密切相关,是企业获取竞争优势的重要因素.     

曲线箱梁桥实用设计方法的研究

曲线箱梁桥目前还缺乏比较实用的设计方法．本文对曲线箱梁桥的现有设计方法作了研究，并推荐一种实用设计方法：采用空间梁单元，每个节点取六个自由度；等效梁格的模拟考虑了横向梁格附近有无横隔梁的情况．结果证明，这是一种简便、较精确的设计方法．     

面向储能的光伏微网成本评价与对策研究

微电网是智能电网的重要组成部分,可以有效协调区域内的电力资源。为研究面向储能的光伏微网电力成本变化情况和优化对策,基于微网多主体结构构建微网电力成本均衡模型,以微网内分布式光伏供应及用户电力需求的统计数据为主要输入对象,并设置变量来区分不同情景下的分布式可再生能源发电量,建立以时间为自变量的微网分布式电力收益函数和用户购电成本函数,刻画微网电力资源调度的动态均衡变化。基于微网电力资源调度实例,发现微网在并网情景下的购电成本小于储能情景下的购电成本（C并=2 033.6元C储=2 633.6元）,且储能情景下购电成本的22.8%都来自储能设施的日折旧费,因此,加大科技研发和增强微网协同管理可以降低微网成本。     

救赎：寻求民族文化的出路——解读莫里森的《柏油孩子》

高速铁路具有高度集成、高精度的技术特点，运营过程中经受列车质量、速度、密度等多种因素影响，地理位置因素往往是影响铁路设备状态演变的决定性因素。采用网格化管理技术可将空间上连续分布的管理对象划分成较小的单元网格，有利于从空间位置角度研究管理对象状态的变化规律。随着信息系统技术、大数据技术的迅猛发展，基于位置而不是基于专业更符合高速铁路的管理需求，网格化管理技术给高速铁路管理带来了新的视角。     

Geo-sampling in developing nations

RTI International created a geospatial grid-based sampling methodology that: achieved a probability-based household sample and unbiased estimates; was comparable across countries; used simple frame data available from the in-country census; and was efficient with minimal training to local field staff. The methodology used 1 km² LandScan world population data, which was further subdivided to smaller grid cells ranging from 50 to 150 m². To guide fieldwork, georeferenced maps were generated and viewed without an Internet connection using a third-party app and the tablet’s internal global positioning systems receiver. The field staff’s location was displayed in real time as a blue dot enabling field staff to determine household inclusivity. This methodology was successfully implemented for household surveys Latin America, Africa, and Asia. The design is transferable, adaptable, scalable, and can be used anywhere in the world.     

What Determines Trust in Information About Food-Related Risks? Underlying Psychological Constructs

Trust in risk information about food related-hazards may be an important determinant of public reactions to risk information. One of the central questions addressed by the risk communication literature is why some individuals and organizations are trusted as sources of risk information and others are not. Industry and government often lack public trust, whereas other sources (for example, consumer organizations, the quality media, medical doctors) are highly trusted. Problematically, previous surveys and questionnaire studies have utilized questions generated by the investigators themselves to assess public perceptions of trust in different sources. Furthermore, no account of the hazard domain was made. In the first study reported here, semistructured interviewing was used to elicit underpinning constructs determining trust and distrust in different sources providing food-related risk information ( n = 35). In the second study, the repertory grid method was used to elicit the terminology that respondents use to distinguish between different potential food-related information sources ( n = 35), the data being submitted to generalised Procrustes analysis. The results of the two studies were combined and validated in survey research ( n = 888) where factor analysis indicated that knowledge in itself does not lead to trust, but that trusted sources are seen to be characterised by multiple positive attributes. Contrary to previous research, complete freedom does not lead to trust—rather sources which possess moderate accountability are seen to be the most trusted.

平面波照明正交光栅时的Talbot效应

本文根据菲涅尔衍射理论,讨论了平面波照明时,两方向周期d_x≠d_y的正交光栅的Talbot效应。指出,两方向周期满足k_x/k_y=(d_y~2)/(d_x~2)的关系时,才能得到完整信息的Talbot像。并据此,引入了混合Talbot像的新概念。给出了一种较Szwaykowski的方法优越的产生正交光栅的方法。并扩展了Szwaykowski的理论。实验结果和理论吻合很好。     

基于网格的电子商务架构和多Agent协商

提出基于网格的电子商务系统架构,它能合理地组织和管理系统中资源和用户,消除信息孤岛,提高信息查询的效率。该架构运用多种Agent完成电子商务过程,有效地反映现实世界交易的特性:其中,使用交易Agent(BA)进行实时监控、采集信息,为协商提供参考值;使用A_(Buyer)和A_(Provider)分别代表买卖双方实施多属性的自主协商,并为之设计灵活、自适应的协商策略,从而提高协商的性能和效率。
