三维打印成形粉末的均匀试验设计研究

利用带限制的混料均匀方法对三维打印成形的粉末配方进行试验设计.对试验数据进行多元非线性回归分析,验证了石膏基粉末中各个成分对三维打印成形制件的影响规律.结果表明,粉末中石膏含量是影响制件密度的关键因素,而聚乙烯醇则可以显著提高制件的表面质量,减小尺寸变形量,白碳黑和聚乙烯醇的交互作用对制件密度和尺寸变形量也有一定的影响.     

自然与科学的对话——现代植物景观的设计手法

讨论高科技的发展是否影响现代植物景观设计手法的转型已成为时代的趋势。本文以“自然与科学的对话”为切入点来讨论现代植物景观的设计手法，具体阐述了高科技在现代植物景观设计手法中的发展条件与运用方式，以及未来的发展方向。从中可以看到，现代植物景观不只是应用、表达科学与技术，还在设计的过程中将现代科技的本质融入植物景观设计构思之中。

Work Design and Integration Glitches in Globally Distributed Technology Projects

In a technology project, project integration represents the pooling together of complete, interdependent task modules to form a physical product or software delivering a desired functionality. This study develops and tests a conceptual framework that examines the interrelationships between the elements of work design, project integration challenges, and project performance. We identify two distinct elements of work design in technology projects: (i) the type of project organization based on whether a technology project spans a firm boundary (Domestic‐Outsourcing) or a country boundary (Offshore‐Insourcing) or both boundaries (Offshore‐Outsourcing) or no boundaries (Domestic‐Insourcing), and (ii) the joint coordination practices among key stakeholders in a technology project—namely, Onsite Ratio and Joint‐Task Ownership. Next, we measure the effectiveness of project integration using integration glitches that capture the incompatibility among interdependent task modules during project integration. Based on analysis of data from 830 technology projects, the results highlight the differential effects of distributed project organizations on integration glitches. Specifically, we find that project organizations that span both firm and country boundaries (Offshore‐Outsourcing) experience significantly higher levels of integration glitches compared to domestic project organizations (Domestic‐Outsourcing and Domestic‐Insourcing). The results further indicate that the relationship between project organization type and integration glitches is moderated by the extent of joint coordination practices in a project. That is, managers can actively lower integration glitches by increasing the levels of onsite ratio and by promoting higher levels of joint‐task ownership, particularly in project organization types that span both firm and country boundaries (Offshore‐Outsourcing). Finally, the results demonstrate the practical significance of studying integration glitches by highlighting its significant negative effect on project performance.     

技术哲学研究中的二元化问题探析

技术人工物的两重性问题、技术伦理的二元划分和技术-社会研究模式确立等二元化问题已然成为时下技术哲学研究的重要视点。结构-功能、结构-意向性的“二元组成”是从技术设计的视角来打开技术黑箱的必由之路;设计伦理和使用伦理的“二元分割”,使得技术伦理研究包括动态嵌入和事后规范两个向度;技术-社会“二元依存”模型的建构,使得技术研究从脱域回归至返域的境遇中来。
