单片机应用系统的软件抗干扰技术

在单片机应用系统中,必须考虑抗干扰的问题。指令冗余、软件陷阱及软件“看门狗”等技术是有效的软件抗干扰措施。干扰后系统复位时,应将重要系统信息从备份中恢复,并将已激活的中断标志清除。     

基于隐马尔可夫模型的本体映射

当前本体映射方法主要考虑结构映射而且映射精度较低,根据统计理论思想,提出了一种基于隐马尔可夫模型的异构本体映射方法.该方法将概念表示为隐马尔可夫模型、概念的特性、关系、上下文、兄弟、规则等表示为隐马尔可夫模型的状态,通过对实例的学习建立隐马尔可夫模型.利用Viterbi算法确定实例所对应的状态序列,然后采用极大似然估计法确定该实例所对应的模型,从而建立异构本体之间的映射.实验表明,该方法有效地提高了异构本体映射的精度.     

同声传译中文化信息冗余的功能性处理

信息冗余是信息论的重要观点,也是中外翻译界学者研究的重要视角。作为信息冗余的一种,文化信息冗余是同声传译中经常出现的现象,对同传译员现场的出色发挥造成很大的困难。通过对同声传译案例的分析,从功能翻译理论的角度剖析文化信息冗余的产生原因并探讨常见的应对策略。     

一项关于大学英语写作冗余错误的研究

本文以中介语理论和语料库为基础,通过分析CLEC语料库中选取的两组英语水平不同的学生作文,重点研究了我国非英语专业学习者在写作中所犯的冗余错误及其原因,并在此基础上,为外语教学提出一些具体建议。     

Stata软件在元分析异质性检验中的运用

研究间异质性检验是合并各独立研究效应量的前提条件.利用Stata软件不仅可制作森林图和Galbraith星状图进行定性分析,而且可以计算Q、I2和H统计量进行定量分析.综合使用两种分析方法能够实现对异质性的准确判断.

知识属性对产业集群企业技术学习策略的影响机制研究

本文深入考察了产业集群中知识属性对企业技术学习策略的影响机制。在实证研究中,本文运用大样本问卷调查数据和层次回归分析方法对理论假设进行检验。研究发现,知识属性对于产业集群企业的技术学习策略存在着显著的影响。具体而言,知识缄默性对产业集群企业深度优先的技术学习策略存在显著的正向影响;知识缄默性和知识异质性对集群企业广度优先的技术学习策略存在显著的负向影响;网络中心性对知识缄默性与产业集群企业技术学习策略之间的关系起着调节作用。     

冗余在英语听力理解中的作用——一项实证研究

Detecting Intervention Effects Across Context: An Examination of the Precision of Cluster Randomized Trials

The Institute of Education Sciences has funded more than 100 experiments to evaluate educational interventions in an effort to generate scientific evidence of program effectiveness on which to base education policy and practice. In general, these studies are designed with the goal of having adequate statistical power to detect the average treatment effect. However, the average treatment effect may be less informative if the treatment effects vary substantially from site to site or if the intervention effects differ across context or subpopulations. This article considers the precision of studies to detect different types of treatment effect heterogeneity. Calculations are demonstrated using a set of Institute of Education Sciences funded cluster randomized trials. Strategies for planning future studies with adequate precision for estimating treatment effect heterogeneity are discussed.     

Doing Diversity Work in Higher Education in Australia

This paper explores how diversity is used as a key term to describe the social and educational mission of universities in Australia. The paper suggests that we need to explore what diversity ‘does’ in specific contexts. Drawing on interviews with diversity and equal opportunities practitioners, the paper suggests that ‘diversity’ is used in the face of what has been called ‘equity fatigue’. Diversity is associated with what is new, and allows practitioners to align themselves and their units with the existing values of their universities. However, given this, diversity can mean potentially anything: and practitioners have to re‐attach the term ‘diversity’ to other more marked terms such as equality and justice if it is to ‘do anything’. The paper explores the appeal of diversity, the strategic nature of diversity work, and the role of commitment, leadership and training. It also offers some more general reflections on how language works within organisations by showing that words, although they do things, are not finished as forms of action: what they do depends not only on how they are used, but how they get taken up.
