PDM 在企业信息集成中的应用研究

PDM 涵盖了产品生命周期的各个方面, 将所有与产品相关的信息和所有与产品相关的过程集成在一起, 是企业信息集成的理想框架。本文研究了如何利用PDM 实现企业CA x 系统之间的集成以及CA x 系统与ERP 系统的集成。     

The effect of anticipated achievement feedback on students' semantic processing as indicated by the N400 cloze effect

The present study examined the effects of anticipated achievement feedback on students' semantic processing on the neural level, using event-related brain potentials (ERPs). Participants (N = 79) anticipated either self-referential or normative achievement feedback regarding an announced upcoming test. Additionally, their performance expectations (low vs. no expectations) were orthogonally manipulated. Subsequently, students' on-line semantic processing was assessed by measuring the N400 cloze effect, a component in the EEG signal of which the amplitude is associated with semantic processing. Within the low performance-expectation condition, no effect of anticipated feedback on semantic processing was found. Within the no-performance-expectation condition, participants anticipating self-referential feedback showed a more widely distributed N400 cloze effect than participants anticipating normative feedback. The results confirmed the hypothesis that the mere expectation of a particular type of feedback can affect students' semantic processes.

外国学生副词“又”习得研究

汉语副词的用法及其在句中位置是非常复杂的。＂又＂可分为五大类15种不同的用法。外国学生学习不可能一次习得它所有的用法,要在不同阶段习得。文章利用测试卷让学生在52个句子适当的位置填上＂又＂,根据测试卷计算出外国学生副词＂又＂习得顺序。总结出比较容易习得的＂又＂以及比较难以习得的＂又＂及其结构,提出一些外国学生副词＂又＂的教学建议。     

谈谈“要么”的语法化

"要么"是现代汉语中常见的一个选择连词,其最早组合是以跨层非短语结构的形式出现在疑问句的末尾,但由于"么"的疑问语气词功能的丧失,致其句法位置发生了转移;在"这么"、"那么"、"怎么"等词类推力量的作用下其进一步词汇化;句中主要动词的存在,促使其词汇化后进一步语法化,而其原型的固有意义使它最终获得了表选择的功能。     

EMDR、适应性信息加工与个案概念化（上）

EMDR是一个整合性的、以咨客为中心的心理治疗方法,它着重于大脑的信息加工系统、烦扰经历的记忆,这些病理学基础不是由器质性的损伤导致的。EMDR强调对临床情境有作用的经历,和那些需要带领咨客达到更健康的心理状态的经历。EMDR作为以经验为主的支持治疗,本文综述其历史、发展和研究,在阐述适应性信息加工模型之后,用一个延续的个案实例来说明了EMDR的个案概念化和8个阶段的治疗。这个方法用于加工那些建立病理学基础的和触发当前功能失调的早期记忆,并为将来恰当的行为提供模板,包括克服技能和（或）发展性的不足所需的知识与行为。整合的EMDR与家庭系统观点的好处是可以提供最综合的治疗效果。     

Intrinsic Factors for Continued ERP Learning: A Precursor to Interdisciplinary ERP Curriculum Design

Unilateral enterprise resource planning (ERP) curriculum improvements from the instructor's perspective are likely to generate only limited success. Understanding student motivations and beliefs with ERP systems is the missing link to effective ERP education. Relatively little attention in the ERP literature has been given to student learning associated with ERP experience, and almost none to factors influencing current and expected student beliefs and behaviors relative to ERP. The complexity of ERP systems demands that beliefs and behaviors be considered when planning ERP curricula. In the present study, the Theory of Planned Behavior was extended to examine students’ intentions to explore additional aspects of ERP after their class exercises. When considering all students, attitude and subjective norm had positive and significant effects on intentions to continue ERP learning. Subjective norm also affected attitude, and availability of support materials had a positive effect on subjective norm. Distinctive patterns are found for the construct relationships between student groups who valued ERP education (the engaged) and those who placed little or no value on ERP education (the undecided). Results from competing model analyses indicate that support materials influenced the engaged and undecided groups differently. Strategies for ERP curriculum design are provided.
