尾草履虫种群增长曲线在水质监测中应用研究

1998年4～6月,对聊城市区主要水域,采用活体采样,研究尾草履虫自然培养中种群增长曲线与水质污染的相关性。结果表明,草履虫培养中种群增长曲线与水域水质的污染程度呈一定的相关性。     

突破场地限制,创造设计特色——以东莞石龙E时代广场方案设计为例

旧城商业改造往往面临用地紧张、停车位不足和新建筑与旧城空间结构易脱离等问题。在东莞E时代广场设计中，建筑师首先将停车与货车车流引入地下（货物通过货梯到达各层），将基地设置为全步行环境。同时将建筑各向开口朝向周边旧城街道，延续了旧城空间交通结构，并在三层屋顶设置屋顶花园，利用大台阶将屋顶花园与街道相连接，将人流引向二、三层，充分发挥各层商业潜力，屋顶花园与基地中心小广场一起构成立体化的绿化景观，还绿地于城市，创造于舒适宜人的绿色购物休闪环境。本研究结合这一具体建筑设计，探讨立体交通、空间对位和绿色共享空间等旧城商业改造中具有普遍意义的手法。     

关于《电路分析基础》教学的探讨

《电路分析基础》是电子信息专业、计算机科学与应用专业和通信工程专业等的专业基础课,比较难学难懂,学生做题时更是无从下手,没有思路。特别是学到正弦稳态电路分析内容时,更是如堕五里云雾中。本文通过借鉴一些有经验的教学方法与自己几年的教学经验相结合,采用了"触类旁通"、"习旧知新"等方法进行教学过程,为改善电路分析教学提供了新的思路。     

西方“个性主义“的合理因素与当代中国价值精神的重构

我国在建设社会主义市场经济价值系统的过程中,可以借鉴和扬弃西方“个性主义“的普遍人类价值因素.在社会层面,借鉴吸收卢梭关于“自由个人构成合理共同体“的思想,克服旧价值观“整体主义“泯灭个性自由的痼疾;在政治层面,借鉴吸取洛克“社会契约论“的民主法制精神,消解旧价值观以“权威主义“剥夺个人主体地位的顽症;在伦理层面,借鉴吸收康德“绝对命令说“的道德精髓,清除旧价值观以“私德至上“否绝个人正当利益的弊端.目前,我们应当看到“个性主义“因其阶级性时代性所限,有可能导致个人主体性的异化,滑向极端利己主义,对此,只能以马克思关于“个人与社会统一为本位“的“人类解放“价值观对其补偏纠弊.     

试析一分为三的原"复指成分"

<中学教学语法系统提要>早已取消复指成分,并对原复指成分进行了更新处理一是列出复指短语,学界已有共识;二是提出不相连的复指,但如何进行结构分析,<提要>未加说明,新时期各种文本的现代汉语也几乎没有涉及,有的仍然坚持"特殊成分"说.对此,该文运用语言事实简要地进行了句法结构方面的归类分析,得出母语语法教学与研究中仍有重视分析"不相连的复指"这种句法结构之必要.     

Power-Based Arbitrary Decisional Actions in the Resolution of MIS Project Issues: A Project Manager's Action Research Perspective

As a management information systems (MIS) project manager and an action researcher, the author examined, over time, the influence on information system development (ISD) of the informal sociopolitical organizational actions. The paper reports two cases of action research findings concerning the effect on ISD project implementation processes of power-based arbitrary decisional actions in bureaucratic environments. The research focused on the relationship of such unilateral actions to the interconnected subprocesses of deliberate and conscious attempts by the ISD project members to define and resolve system implementation issues. A suggested conceptual framework for the issue-resolution processes (IRP's) and obstacle-coping processes (OCP's) is based on the author's IRP/OCP-related behavioral constructs and theoretical models dealing with soft-systems issues, especially appreciative system theory and soft-systems methodology, and innovative flexible, "complementarist" (Sinn, 1998) or pluralist problem-solving approaches.

Neural correlation of item recognition and voice source retrieval

An experiment was conducted using event-related potentials to investigate the old/new effects of the item recognition and the voice source retrieval tasks on drawing. The results indicated that (1) the old/new effect for the voice source retrieval task was much wider than that of the item recognition task; (2) the distributive characteristics of the voice source memory effect were different from those in previous studies; (3) the old/new effects for target and non-target-old drawings were similar. These results demonstrated that the voice source retrieval task is more difficult than the item recognition task for drawing, which supports the dual-process model. The experimental material and the source characteristic regulate the spatial and temporal distributions of the old/new effect for the voice source retrieval task together.
