Active changes of lignification-related enzymes in pepper response to Glomus intraradices and/or Phytophthora capsici

INTRODUCTION Plants have defense mechanisms against patho-gen infection by inducing systemic resistance in re-sponse to localized pretreatment with biological cotrol agents, thus making them resistant to subsequpathogen infection (Caruso et al., 1999; Hammschmidt, 1999; Mohammadi and Kazemi, 2002; yada et al., 1995; Pozo et al., 2002; Ray et al., 199Biological control of plant pathogens has receivmuch more attention.

The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.

软件系统项目开发内在风险灰色评价模型研究

项目的风险评价是确保项目投资成功的重要环节。传统的评价方法以财务数据为依据，通过技术经济指标体系．结合敏感性分析、概率分析和风险决策方法等，对项目投资的外在风险进行预测和评价，但却忽略其内在风险。故从项目立项启动风险和项目实施风险两个方面阐述了企业软件系统项目的内在风险，提出基于灰色理论的软件系统项目内在风险评价模型和灰评价计算方法，为企业的软件系统项目开发决策提供有力的分析工具。
