非线性MIMO级联数据库频繁访问特征分区技术

多输入输出(MIMO)级联数据库广泛应用在大型电子设备故障诊断数据库架构中。对MIMO级联数据库频繁访问过程中,进行特征分区有利于提高数据库访问性能。提出一种基于属性集合幂集的区间概念格的非线性MIMO级联数据库频繁访问特征分区算法,进行MIMO级联数据库的非线性特征分析及区间概念格构造,对数据库子系统的状态矢量进行临界状态数学建模,构建数据库的特征分区目标函数,改进MIMO级联数据库频繁访问特征分区性能。仿真实验表明,该算法能准确实现对非线性MIMO级联数据库频繁访问特征的提取和分区处理,有效提高了对MIMO级联数据库的内部访问特征的分析能力,有利于提高数据库访问性能,大幅提高数据检测性能,为构建专家系统奠定基础。     

论文化批评的当下性

20世纪90年代以来，全球化背景下科学技术的发展引起社会主导传媒形式的变化，而主导传媒形式的变化引起了原来艺术生态格局的变化。在文学不断向泛文学的转变过程中，文化批评面对当下的文学景观，从关心纯文学到关注泛文学，从关怀终极价值到关怀世俗，从回避问题到自觉批判，从单一视角到整体观照，从重视宏观理论到关注微观个案，从独尊话语的思维到多元思维，显示了极强的现实回应能力和阐释能力。     

Writers' retreats for academics: exploring and increasing the motivation to write

This paper examines the literature on academic writing and collaborative learning and proposes, in the light of this literature, that the introduction of writers' retreats for academics represents a valuable professional development opportunity. It is argued that such an intervention can be an important initiative, helping to support more productive patterns of academic writing among participating academics. Findings gathered during a writers' retreat are presented, focusing on the positive and negative perspectives that participating academics expressed about writing for publication. The format and the structure of the retreat are described, along with the impact that such an intervention can be argued to have made on participants. Finally, a conceptual map is presented which relates the experiences and insights of the retreat to the ‘motivation to write’ among academics.     

教学理论知识的地方性建构——兼论教学流派的创生

“普遍主义”是一个时期教学理论研究的“具象”,它框定了教学理论研究的思维方式。“普遍主义”秉承现代知识观,是对马克思主义认识论形而上学化的产物。“地方性知识”是对“普遍主义”知识观的时代“消解”,在此,知识是“个人”的、境域的,对知识的辩护随着知识的生成过程的观念合理导引了教学理论研究的方向——教学理论研究应该倡导教学流派理念,并回归教学生活世界。     

In search of a middle ground: the dangers and affordances of diagnosis in relation to Attention Deficit Hyperactivity Disorder and Developmental Language Disorder

ABSTRACT

In this paper, we draw on the ‘dilemma of difference’ to discuss the dangers and affordances of diagnosis within two of the most prevalent, yet under-supported, disabilities affecting school-age children: Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Language Disorder (DLD). The dilemma that exists between denying and thereby ignoring difference on the one hand, versus recognising and potentially stigmatising difference on the other, will be explored and the consequences outlined. Our aim is to achieve a middle ground that conceives of diagnosis as a helpful starting point to enable educators to address barriers to access and participation through appropriate adjustments to curriculum, pedagogy and assessment.     

Managerialism and equalities: tensions within widening access policy and practice for disabled students in UK universities

This paper draws on a four-year longitudinal ESRC funded project examining learning experiences of disabled students in higher education in four universities. The focus here is on institutional responses to the demands of audit culture and legislation in relation to making reasonable adjustments for students with impairments. The data comes from institutional documents and face-to-face interviews with key informants within the institutions. The findings indicate that quality assurance regimes and legislation have had some positive effect on improving access for disabled students; however, local factors and type of institution also have a major impact on the way that national policies are expressed in particular contexts.

The role of scaling up research in designing for and evaluating robustness

One of the great strengths of Jim Kaput’s research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, “democratizing access to the mathematics of change,” was enacted by deliberate efforts to reach an increasing number of teachers and students each year. Further, Kaput asked: What can we learn from research at the next level of scale (e.g., beyond a few classrooms at a time) that we cannot learn from other sources? In this article, we develop an argument that scaling up research can contribute important new knowledge by focusing researchers’ attention on the robustness of an innovation when used by varied students, teachers, classrooms, schools, and regions. The concept of robustness requires additional discipline both in the design process and in the conduct of valid research. By examining a progression of three studies in the Scaling Up SimCalc program, we articulate how scaling up research can contribute to designing for and evaluating robustness.
