A conceptualization of intended learning outcomes supporting self‐regulated learners in indicating learning paths

Intended learning outcomes (ILOs) indicate what learners will be able to achieve after they are taught. Traditionally, ILOs are expressed as plain text or unstructured documents. What if all ILOs of a specific course of study can be conceptualized through a structured diagrammatic technique? It was hypothesized that learners can benefit from this conceptualization in learning, especially in self‐regulated learning. The aim of this study was to investigate whether the ILOs represented in unstructured or structured formats can facilitate learners to identify learning paths. The results revealed that the mean ratings of all learning paths were statistically significantly higher with structured ILOs.     

An integrative conceptual framework of disability: New directions for research.

Advances in research on disability and rehabilitation are essential to creating equal opportunity, economic self-sufficiency, and full participation for persons with disabilities. Historically, such initiatives have focused on separate and specific areas, including neuroscience, molecular biology and genetics, gerontology, engineering and physical sciences, and social and behavioral sciences. Research on persons with disabilities should examine the broader context and trends of society that affect the total environment of persons with disabilities. This article examines the various disability paradigms across time, assessing the relative contribution of the socioecological perspective in guiding research designed to improve the lives of persons with disabilities. The authors recommend new research directions that include a focus on life span issues, biomedicine, biotechnology, the efficacy and effectiveness of current interventions, an emphasis on consumer-driven investigations within a socioecological perspective of disability, and the implications for research and practice.

Distinctiveness and Correlation in Conceptual Structure: Behavioral and Computational Studies.

Patients with category-specific deficits have motivated a range of hypotheses about the structure of the conceptual system. One class of models claims that apparent category dissociations emerge from the internal structure of concepts rather than fractionation of the system into separate substores. This account claims that distinctive properties of concepts in the living domain are vulnerable because of their weak correlation with other features. Given the assumption that mutual activation among correlated properties produces faster activation in the normal system, the authors predicted a disadvantage for the distinctive features of living things for unimpaired adults. Results of a speeded feature verification study supported this prediction, as did a computational simulation in which networks mapped from orthography to semantics.

磁悬浮列车造型仿生设计研究

以仿生设计的理论为基础来指导磁悬浮列车造型设计,以期为列车车型概念提供灵感,提高列车造型品质,并满足车体气动性能的基本要求。首先,通过文献研究归纳了国内外以磁悬浮列车为主的轨道列车造型仿生的研究动向;其次,通过案例研究解析典型仿生设计系列车型案例,探究列车仿生对象的应用形式;再次,综合仿生设计与轨道列车设计的方法要素,构建磁悬浮列车仿生设计的一般程序,并基于车体线性趋势的仿生规律,以平鳍旗鱼为仿生对象,设计具有仿生特征的磁悬浮列车概念性设计造型方案;最后,通过初步的仿真模拟,得到该方案的空气阻力系数。通过将本方案与相关案例数据的对比,证明运用仿生设计可以满足磁悬浮列车造型对美学价值和气动性能的要求。     

并列短语及其词序的认知语言学研究

有关并列短语及其词序的研究目前主要存在四方面的问题：“并列短语”的概念之争、并列短语的界定、并列短语与并列复合词的异同、并列短语的词序。为解决这些问题与分歧,认知语言学的基本观点、假设、范畴的原型观、语言的象似观、概念整合理论以及词汇化和短语固化等理论和观点构成研究并列短语及其词序的理论基础,该理论能在一定程度上对以上问题作出合理的解释。根据范畴的原型观,并列短语具有典型性,为并列短语及其词序研究尤其是定量研究提供了理论基础;象似性在并列短语中大量存在,尤其是顺序象似或时间顺序原则,在汉语中尤为明显;词语整合具有层级性,并列短语在词汇化和固化程度上的不同,与概念的整合层级性相关。

语义桌面环境下一种基于概念图的文档检索方法

语义桌面作为语义Web的一个重要分支,可以为个人计算机用户提供丰富的元数据,用以记录桌面文档的各种特征。这些特征包括文件的常规属性和与用户行为相关的属性,它们为桌面文档检索提供帮助。受到"概念图"理论的启发,本文提出了一种语义桌面环境下的文档检索算法。该算法能有效地利用语义桌面提供的元数据建立一种便于快速查找的文档索引结构,迅速地确定用户查询与桌面文档之间的投影算子。实验表明,该算法的时间效率比以往的基于匹配推理的投影算法有很大的提高,可以在很大程度上满足用户对桌面文档进行快速检索的需求。
