试论科学精神与人的发展

科技作为第一生产力内在地包含科学精神;而科学的怀疑精神、批判精神、求实精神、创新精神构成了科学精神的基本内涵。社会分工在一定程度上造成了科学精神的缺失,要促进人的全面发展必须重视科学精神的培育。     

基于个体经验的信任模型研究

为了提高分布式网络中各节点信任评价的准确度,提出了一种基于个体经验的信任模型.该模型通过引入经验因子和相对经验因子的方法,建立了新的信任评价体系.这种新的信任评价体系考虑了个体节点的差异问题,在计算节点的信任值时考虑了节点间的交互历史,这在一定程度上解决了由于节点的非对称性而导致的信任评价不准确的问题.算法分析表明:新模型能够针对不同的个体节点,采用不同的最大容忍评价偏差,并且对个体节点的反馈可信度进行更新时,采用不同的更新值,体现了节点的个性化特征,使信任评价更加准确合理.此外,所提出的新算法能够运用到多种信任模型中,具有很好的可扩展性.     

‘We’re not the hottest ethnicity’: Pacific scholars and the cultural politics of New Zealand universities

ABSTRACT

Academic labour markets around the world are increasingly globalised and tied to transnational circuits of neoliberal capital. Universities in New Zealand are closely aligned with these trends and an academic labour force has developed over time that reflects these economic flows and currents. This labour force is characterised by an exceptionally high number of multinational academic staff, many of whom contribute to research and inquiry aimed at maintaining and broadening the influence of their institutions abroad. Pacific faculty, however, experience the micro-geographies of New Zealand universities in different ways from other migrant scholars, especially those who hail from the global North. They are rarely included in academic ‘prestige economies’ or elite scholarly networks and are often isolated in their academic departments. This paper draws on a study about the experiences of senior Pacific academics in Aotearoa New Zealand and explores how they formulate pan-Pacific solidarities within the neoliberal and settler-colonial milieu of higher education. We focus on the often fraught dynamics of encounters between Pacific scholars, white academic elites and indigenous Māori colleagues as they map academic identities on to institutional space.     

搭建学生自主学习的平台

充分发挥学生自主性是培养学生自主构建知识、发展能力,形成正确的情感态度与价值观的需要,是培养学生创新精神和实践能力的需要.教师要创设条件,改"铺垫搭桥"式导言为"创设问题情境"式,激发学生探索的欲望,培养探索的兴趣;改"被动接受--记忆"式学习为"主动探究--发现"式学习、改教学时空狭隘性为广延性、改师道尊严为合作伙伴,让学生充分地探索与思考,在独立思考的基础上合作交流,体会奋斗的艰辛、成功的喜悦.     

关注学生学习过程的学业评价——南澳洲中学教学过程中的学生学业评价

学生学习过程中的评价问题是学校教学中的重要问题。在现代学校教学改革的过程中,越来越关注对学生学习过程的评价,越来越重视学生在学校过程中的表现性评价。澳大利亚南澳州的中学阶段,在课程建设和教学过程中逐渐形成了比较严格的学生学业评价体系,这种评价体系不仅关注学生相关测验或考试的分数,更体现着一种注重学生学习过程的学业评价,体现着一种注重学生学习过程的学业评价理念。     

"吟咏情性":钟嵘诗歌本质论在《诗品》中的地位和作用

《诗品》中“吟咏情性”的诗歌本质论是钟嵘批驳当时不良文风的出发点,是他的诗论思想中最具统摄性的命题。本文试图论说这一本质论在其诗论思想中的地位和作用。     

晚清时期西北地区的烟毒与禁政

本文研究了晚清时期西北地区从烟毒输入地到烟毒输出地的变迁和由此引起的西北地方政府在不同时期对烟毒的措施和对策,并从历史环境、文化心理、人文地理、法学等角度讨论了鸦片在西北地区蔓延及屡禁不止的原因.     

Continuous robust tracking controllers for a class of uncertain nonlinear dynamical systems

Robust tracking controller for a class of uncertain nonlinear dynamical systems, which are linearizable by input-output feedback with matching uncertainties, was investigated. In this study, uniform ultimate bound or uniformly asymptotic stability of tracking errors were obtained by different choice of the control gain. A simulation to determine the effectiveness of the proposed approach showed that the control performance was better than that of VSC (Variable Structure Control).
