Word learning: An ERP investigation of word experience effects on recognition and word processing

Adults of varying reading comprehension skill learned a set of previously unknown rare English words (e.g., gloaming) in three different learning conditions in which the type of word knowledge was manipulated. The words were presented in one of three conditions: (1) orthography-to-meaning (no phonology); (2) orthography-to-phonology (no meaning); and (3) phonology-to-meaning (no orthography). Following learning, participants made meaning judgments on the learned words, familiar known words, and unpresented (unlearned) rare words while their ERPs were recorded. The behavioral results showed no significant effects of comprehension skill on meaning judgment performance. Contrastingly, the ERP results indicated comprehension skill differences in P600 amplitude; high-skilled readers showed stronger familiarity effects for learned words, whereas less-skilled readers did not distinguish between learned words, familiar words, and unlearned words. Evidence from the P600 and N400 illustrated superior learning of meaning when meaning information was coupled with orthography rather than phonology. These results suggest that the availability of word knowledge (orthography, phonology, and meaning) at learning affects subsequent word identification processes when the words are encountered in a new context.     

ERP投资与企业绩效关系的调节因素研究

IT价值研究一直是信息系统研究中的重要理论和实践问题。企业资源规划系统(ERP)作为企业不可或缺的IT应用,是保持企业活力和竞争力的必要条件,对企业的生存和发展至关重要。目前,国内外学术界缺乏对ERP投资与企业绩效关系的调节因素研究。以1998-2007年沪深A股上市公司的129家企业为样本,使用面板数据模型,研究了公司治理、多元化,以及ERP实施区间的调节作用。研究结果表明,公司治理对于ERP投资和企业绩效的关系存在正向调节作用;多元化程度高的企业在实施ERP后,其绩效表现低于多元化程度低的企业;普及期的ERP投资相比发展期的ERP投资有更好的绩效表现。

沙盘在高级财务会计教学改革中的应用研究

传统的高级财务会计教学都是重理论,轻实践,教师仍然在课堂中占据主要地位。而高级财务会计这门课程实际上一门与企业结合非常密切的课程,要求学生的实践应用能力强,所以有必要将沙盘引入到课堂教学中,有效地激发学生的兴趣,使学生运动更好地将理论应用于实践。     

基于会计信息化视角下的企业内部控制研究

近些年来会计电算化逐渐代替了传统会计,随之由于会计业务执行主体的变化,使得内部控制的特点也发生了转变。因而要做好会计信息系统开发与维护工作,提高内部控制的组织与管理,保证会计信息系统安全、高效运行。     

ERP环境下基于数据仓库技术的产品质量管理

文章介绍了ERP、数据仓库等的相关概念以及数据仓库的特性。以某机械加工工厂为例,以其正在运行的ERP为基础,基于SQL Server 2008的B(IBusiness Intelligence,商业智能),采用数据仓库及OLAP(On-Line Analytical Processing,联机分析处理)技术,使用多维数据集分析技术对机械加工中的生产数据进行分析,管理者可及时获得相关信息,调整生产过程,从而可以保质保量的生产合格产品,为企业长期发展提供技术支持。

The influence of ERP system implementation on the operational performance of an organization

We investigate changes in operational performance that result from enterprise resource planning (ERP) system implementation. A literature-based and theory-driven model was developed to examine the relationship between ERP system implementation status and operational performance. Data were gathered through a field study to test the hypothesized relationships. The results indicate that the implementation of each ERP system module influences operational performance measures differently. In addition, the results highlight the varying influence of the implementation of the ERP system, as a whole, on operational performance measures. Our findings suggest that a better understanding of the contribution of ERP systems to operational performance can be obtained if researchers and managers assess changes in operational performance at both the modular and the system levels.
