大学化学实验课程中有效数字的记录

有效数字是大学化学实验课程的主要教学内容之一,是培养学生在课程中理解并在日常学习与工作中规范使用有效数字,提升其对有效数字与测定误差之间关系的认识水平,树立良好规范的数字记录习惯,具有十分重要的现实意义。论述介绍了目前大学化学实验教学中关于有效数字方面存在的主要问题,并采用相应的举措建立和完善了教学方案以利于更好地解决存在的问题。通过几个学期的教学实践发现新教学方案取得了初步的成效,同时严格按照有效数字的要求记录与计算数据也是培养学生具有严谨科学素养的一条重要途径。     

基于重大偏差标准的软件项目工作量管理方法研究

为有效管理软件项目工作量,本文研究了一个基于重大偏差标准的软件项目工作量管理模型。该模型利用过程控制的原理和数理统计的方法,提出依据重大偏差标准和风险储备时间对软件项目进行动态控制,并介绍了风险储备时间与重大偏差标准的定量设置方法。该模型涵盖了从风险储备时间的确定,到重大偏差标准的提出,再根据风险储备时间和重大偏差标准进行监控的整个过程。为提高软件项目管理精度,保证项目在可接受的偏差范围内顺利完成打下坚实的基础。

A modified LGB method for detecting significant effects based on a half-normal probability plot

In analyzing data from unreplicated factorial designs, the half-normal probability plot is commonly used to screen for the ‘vital few’ effects. Recently, many formal methods have been proposed to overcome the subjectivity of this plot. Lawson (1998) (hereafter denoted as LGB) suggested a hybrid method based on the half-normal probability plot, which is a blend of Lenth (1989) and Loh (1992) method. The method consists of fitting a simple least squares line to the inliers, which are determined by the Lenth method. The effects exceeding the prediction limits based on the fitted line are candidates for the vital few effects. To improve the accuracy of partitioning the effects into inliers and outliers, we propose a modified LGB method (hereafter denoted as the Mod_LGB method), in which more outliers can be classified by using both the Carling’s modification of the box plot (Carling, 2000) and Lenth method. If no outlier exists or there is a wide range in the inliers as determined by the Lenth method, more outliers can be found by the Carling method. A simulation study is conducted in unreplicated $2^4$ designs with the number of active effects ranging from 1 to 6 to compare the efficiency of the Lenth method, original LGB methods, and the proposed modified version of the LGB method.     

A Study of a Network Meeting: Exploring the Interplay between Inner and Outer Dialogues in Significant and Meaningful Moments

The present study is part of a series of qualitative studies focusing on dialogic practice in southern Norway. In this article, we present a qualitative study of a network meeting focusing on the interplay between the participants' inner and outer dialogues. The network meeting is between an adolescent boy, his mother and two network therapists, the same adolescent case discussed previously in this journal by Bøe et al. ( 2013 ). The aim of this study is to explore how the interplay between inner and outer dialogues contributes to significant and meaningful moments for the interlocutors. A multiperspective methodology is used that combines video recordings of a network meeting and participant interviews with text analysis. Our research found the interplay has an important role in understanding the emergence of significant and meaningful moments in therapy. A one‐sided focus on participants' utterances or inner dialogues was insufficient to explain their significance and meaning to the interlocutors. A dialogical approach provides a theoretical frame and concepts that are useful in investigations of therapeutic conversations.     

语篇衔接与英语习得程度调查分析

通过对大学非英语专业学生的英语议论文写作中使用的语篇连接词进行统计分析,探讨学习者语篇衔接意识和能力与英语习得程度的关系。研究结果发现:1)学习者使用连接词的意识和能力与他们的英语习得程度有关系;2)英语习得程度好的学习者与程度差的学习者所使用的连接词在总数和类别数量上有显著差异;3)在议论文体中所使用的连接词存在单一的特点。     

走出国有资产转让的三大认识误区

国有资产转让是国企改革的重要组成部分,其成败将直接影响、甚至决定国企改革的进程与结果。我们必须走出账面价值的认识误区,注重未来预期收益的“折现值”,走出资产流失的认识误区,注重资产流失与假资产流失之名行捣乱非流失资产转让之实的双重防范;走出否定国有资产转让的误区,充分意识因噎废食有可能拒一切转机于门外,而完善法规则可以亡羊补牢。     

论科技英语中wh-words引导名词性从句的用法

科技英语因其自身特点而成为一个独特的语域.wh-words可以用来引导各种从句.文章研究在科技英语中wh-words的句法功能,重点研究wh-words引导名词性从句的用法.运用统计学方法对wh-words在科技英语(T4)等语料库中的分布频率进行分析,根据卡方测试的结果做出判断.wh-words在不同的从句中使用的频率高低不等,有些wh-words在不同的语料库中的分布存在着显著不同,如what等词.因此,在某种程度上可以说,wh-words这一组词的用法特点是科技英语区别于普通英语的一个反映.     

拓展型高等院校分校服务地方的三个基本误区及反思

拓展型高等院校分校作为三大类型分校之一,其重要使命在于直接有效地促进当地经济社会和自身的发展。但在其服务地方经济和社会发展过程中,极易陷入三个基本误区：对服务应有地位的认定误区、对服务主体的认知误区以及对服务方式的理解误区。在分析以上误区的基础上,文章从三个方面探索了拓展型高等院校分校服务地方的可行之路：从使命角度而不仅是服务职能来认定拓展型高等院校分校的＂服务＂;从服务＂机构＂和服务的＂人＂角度,确定服务的＂双主体＂特性;打破服务方式的直接性和均衡性,形成以＂学＂为主、＂产＂＂学＂互动的间接服务方式。
