关于计算机技术与图书馆建设的几点思考

为适应社会信息化发展的需要,图书馆采用计算机技术,实行互联网,为广大用户提供信息和情报资料等各方面优质服务势在必行。目前,图书馆建设应从以下四方面着手：第一,转变观念;第二,基础设设技术必须加强;第三,必须加强图书馆工作人员队伍建设;第四,加大资金投入。     

Supplier Development Practices for Sustainability: A Multi‐Stakeholder Perspective

Supplier development for sustainability is a critical element of sustainable supply chain management and requires extensive multi‐stakeholder collaboration. This article establishes a conceptual four‐stage framework to analyse the collaborative mechanisms of supplier development practices, and presents an exploratory, qualitative analysis to identify the major contributors of sustainable supplier development practices, such as NGOs, industrial associations, consulting firms etc. Based on semi‐structured interviews about 63 organizations from different regions and industries, this article identifies three types of contributor: drivers, facilitators and inspectors. Instead of traditional stakeholder engagement processes, these contributors actively collaborate with buying firms and suppliers to design, implement and evaluate sustainable supplier development programs. The article then provides a matrix to describe the supply chain coverage and supplier performance of supplier development practices, given the absence or positive involvement of facilitators and inspectors. We conclude our study by suggesting future research directions as well as discussing managerial implications. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

基于数字图像处理技术的再生混凝土数值模拟

为了研究骨料形态对再生混凝土材料力学性能的影响,基于势能原理的基面力元法,利用图像处理技术和MATLAB软件,建立了再生混凝土真实骨料细观模型。应用FORTRAN分析软件对再生混凝土试件进行单轴拉伸试验的数值模拟,研究了真实骨料细观模型再生混凝土宏观应力-应变曲线变化规律和试件的破坏形态。结果显示,真实骨料模型得到的宏观应力-应变曲线和试验曲线吻合度较高,骨料形状对试件的破坏形态影响较小。模型可真实地模拟再生混凝土在单轴拉伸作用下的损伤破坏过程,准确地反映试件的实际骨料形态。     

Moving freight on public transit: Best practices,challenges, and opportunities

Freight on Transit (FOT) refers to an operational strategy where public transit vehicles and/or infrastructure are used to move freight. Examples include moving goods alongside passengers on buses, attaching cargo trailers to transit vehicles, and operating freight vehicles between trains on subway lines. This paper describes the methods and results of a three-round Delphi study engaging 34 transportation experts to explore challenges and opportunities of FOT and to conceptualize and evaluate potential FOT operations in Toronto. Traditional Delphi methods were used for the exploration of FOT challenges and opportunities, and a modified approach was formulated to integrate experts' opinions and develop new FOT concepts for Toronto. The results support previous claims that technical challenges of FOT may be easier to overcome than institutional barriers. Evaluation of potential FOT operating strategies in Toronto suggests that while the current public transit network does not have capacity to support additional movements, there may be realistic opportunities to include freight service in future projects as a means of offsetting operating costs and reducing the impacts of goods movements.     

多跨连续-刚构桥梁施工的高程及应力控制——以新疆克其克苏布台大桥为例

为实现桥梁施工精度的准确控制,保证桥梁施工质量符合设计要求,对某多跨连续-刚构桥梁的施工控制进行了计算分析。首先,通过理论计算桥梁的预拱度,并在施工过程中采取相应的高程及应力控制措施;其次,通过现场实测,对施工过程中的高程及应力进行实时监测,将监测值与控制值进行比较,以评价控制效果。实例检验结果表明:在高程控制方面,最终合龙高程误差不超过8mm,满足了桥梁的线型要求;在应力控制方面,主梁和墩身应力均为压应力,且远小于规范限值,满足设计要求。因此,在桥梁施工过程中,通过理论计算与施工控制相结合的方法,能够实现桥梁高程及应力的有效控制,达到预期效果。桥梁施工控制措施的有效性在研究中得到了验证,可为类似桥梁施工提供参考。     

试析住宅区区分所有权

我国住宅区因共有部分权属模糊、开发商任意分割销售导致大量纠纷的产生,通过对建筑物区分所有权(distinguishable ownership of building)、住宅区等概念的分析,得出住宅区区分所有权(distin-guishable ownership of residential district)的基本定义,从而对住宅区法定共有部分、住宅区专有部分的特征进行界定。
