Matters of Form: Questions of Race,Identity, Design,and the U.S. Census

This case examines how functionalist approaches manifest culturally based on users’ contexts. The authors conduct a critical visual semiotic analysis of the race and Hispanic origin questions on the 2010 U.S. Census form, demonstrating how incongruities in design potentially harm people. This demonstrates a need for adding critical analyses to design and research and it refocuses the Society for Technical Communication’s value of promoting the public good on to design and documentation in order to fight injustice.

Political and educational springboard or straitjacket? Theorising post/human subjects in an age of vulnerability

Contemporary discourses of social justice in education, disability, mental health, social policy and feminist studies are refracted increasingly through concerns about psychological and structural vulnerabilities created by the crises of late capitalism. Focusing on developments in British social policy generally and educational research specifically, this paper uses the authors' contrasting perspectives on two discernible discourses of vulnerability emerging in these contexts. One elevates the recognition of collective vulnerability as a springboard for new conceptualisations of resistance that disrupt materialist narratives of the human subject as a coherent, unified and rational agent of history. A second discourse offers a materialist understanding that locates vulnerability as both driver and product of a ‘therapeutic culture’, arguing that a psycho-emotional focus for vulnerability offers a diminished and ineffective subjectivity that belies rhetorics of resistance. These contrasting perspectives generate and emerge simultaneously from new understandings of the human subject. The paper evaluates the implications of using vulnerability to frame expectations of human subjects for everyday educational practices and relationships. It concludes by suggesting empirical questions that need exploring.     

如何培养学生的空间想象能力

随着计算机技术的不断发展 ,计算机辅助绘图技术使传统的二维绘图发生了本质的变化 ,因此产品设计等可在计算机屏幕上进行三维实体造型 ,来代替传统的手工绘图 ,从而使制图人员从繁重的手工绘图工作中解放出来。教学是为生产服务的 ,所以在机制图教学中培养学生的空间想象能力需加强三维绘图的教学研究     

GC/FTIR联用法鉴定纸用人造香料

采用GC／FTIR联用技术对一种纸用人造香料的组成进行了定性、定量鉴定。比较了不同色谱柱的分离效果，选择Supelco wax^TM-10色谱柱对该香料进行分离。采用红外光谱对香料组成进行了鉴定，确定该香料由28种组分组成，其主要成份为醛类、酯类、醚类、醇类化合物，此外还含有少量的酮类、酚类化合物。     

Exploring a new silent test of phonological awareness

This is the preliminary study of a test of phonologicalawareness which does not require that subjects speak or hear toparticipate. The test was designed to minimize memory loads, and tomeasure speeded written naming and segmentation-by-sound. Spelling datacan also be collected. Subjects have 45 seconds to name items in each oftwo sets of line drawings. The average frequency of the names variesacross these sets. In the third set, subjects must name the items, andalso segment the written names into their constituent sounds. This taskwas administered to disabled and normally-reading adults, with twocommon tests of phonological awareness. The new test discriminatedbetween the readers as reliably as the benchmark tasks, correlating witheach better than they correlated with each other. The new test was thenadministered to deaf adults, who performed similarly to the disabled(hearing) readers. The data represent the first direct demonstration ofphonological abilities in deaf subjects, using a task designedspecifically for that purpose.     

基于Web模式可移植性训练系统的设计与实现

三层结构模式在Web应用系统中广泛应用，但也存在不足之处：系统对网络环境完全依赖，网络资源利用不平衡．因此，从一个基于Web模式的训练教学系统的设计和实现过程，对Web三层结构提出了调整改进措施，在设计中构建了具有一定逻辑功能的Web页面数据单元，从而实现数据的重用性和系统设计的可移植性，并有效地解决了Web三层结构系统的不足之处．     

动态评估及其在特殊教育中的应用

动态评估是一种新型的评估方式,把它应用到特殊教育中也是近些年才兴起来的。文章对动态评估的概念和理论基础进行简单的介绍,然后分析了动态评估对特殊教育的价值意义以及动态评估在特殊教育应用过程中所产生的问题,并提出了改进建议。     

汉英句式的动态转换

本文以“功能对等”翻译理论为依据,比较了汉英句式表达上的差异,如意合与形合,句首开放与句尾开放,话题句与主谓句等,认为翻译应重在以语义为基础的动态转换。
