在企事业单位内部,由于部门间相对独立,构建系统时缺乏统一的规划和标准。所以造成了现有的应用系统是分散、异构、封闭的系统,相互之间不能共享信息,形成了一个个“信息孤岛”．本文首先对数据集成涉及的相关技术进行了研究．分析了目前流行的数据集成方法．按照不同的实现技术,将数据集成方法分为三类,即数据转换方法、数据聚合方法以及析取、转换和装载（Exact、Transform and Load,ETL）方法．然后,借鉴数据转换方法以及ETL方法的数据集成实现思想,结合目前中小企业数据集成的需求,提出基于Java和XML技术实现异构数据交换集成的通用解决方案． 相似文献

分布式认知及其对学习环境设计的影响 总被引：1，自引：0，他引：1
分布式认知理论认为认知分布于个体、群体和人工制品之中。其中,个体和人工制品同样重要,群体和人工制品也同样重要。今天,信息技术的发展日益凸显人工制品的价值。在学习活动中,"学习环境"即为"人工制品";分布式认知对人类认知活动和人工制品的认识即为分析学习环境设计的一种理论框架。它基于"认知分布"的视角对学习环境赋予新的隐喻,给予学习环境设计新的启示。这为学习者的有意义学习创设环境提供了有力的"给养"。 相似文献

A new framework for consciousness is introduced based upon traditional artificial neural network models. This framework reflects explicit connections between two parts of the brain: one global working memory and distributed modular cerebral networks relating to specific brain functions. Accordingly this framework is composed of three layers,physical mnemonic layer and abstract thinking layer,which cooperate together through a recognition layer to accomplish information storage and cognition using algorithms of how these interactions contribute to consciousness:(1)the reception process whereby cerebral subsystems group distributed signals into coherent object patterns;(2)the partial recognition process whereby patterns from particular subsystems are compared or stored as knowledge; and(3)the resonant learning process whereby global workspace stably adjusts its structure to adapt to patterns' changes. Using this framework,various sorts of human actions can be explained,leading to a general approach for analyzing brain functions. 相似文献

蠕虫已成为全球网络最严重的安全威胁,但由于其有别于其他攻击方法的特点,现有的网络防御方法对蠕虫的攻击显得无能为力。针对传统防御方法在防御蠕虫入侵方面的不足,在针对网络蠕虫攻击特点的基础上,提出一个新的分布式入侵检测框架,来尽早发现蠕虫的踪迹,并立即进行防御。此框架不仅能够实时检测未知类型的网络蠕虫攻击,还能分析蠕虫攻击中扫描过程的网络传输特征和在网络内可能感染的主机列表。基于框架原型系统对CodeRed II蠕虫攻击检测得到的实验结果,证明该框架对蠕虫的早期扫描行为更加敏感,并具有更低的误报率。 相似文献

Since its inception in 1999, the distributed leadership framework of Spillane, Halverson, and Diamond [2004. “Towards a Theory of Leadership Practice: A Distributed Perspective.” Journal of Curriculum Studies 36 (1): 3–34. doi:10.1080/0022027032000106726] has supported research into leadership and change in schools. Whilst the conceptual integrity of the framework is sound, research based upon its premises has attracted some criticism. The research has had a narrowed focus which has not generally reflected the inseparability of the elements of the framework and the situation within which leadership is enacted. In addition, it often fails to account for the complexity of critical elements of the environment such as micropolitics. This position paper proposes a reconfiguration of the distributed leadership framework as a research framework in response to this critique. The paper asserts that this new perspective that is presented is able to respond to the critique through an integrated approach that encompasses situation, social distribution and task enactment and which supports an integrated approach to research methodology. This adapted framework has the potential to more fully support research design that is actuality holistic and embedded in the context. 相似文献

Over the last 20 years, the tertiary education sector has adopted new administrative management approaches, with the aim of improving accountable and strategic focus. Over the same period, the question of how to build leadership capacity to improve learning and teaching and research outcomes has led to discussion on what constitutes academic leadership. While both these advances are needed, what is missing is integration between the two such that academics and professional staff are engaged collaboratively to achieve learning and teaching and research outcomes that are accountable within a strategic focus. This article builds on research into the use of distributed leadership to build leadership for learning and teaching that resulted in the design of a conceptual framework for distributed leadership. Based on this conceptual framework, it proposes a conceptual blended leadership approach to engage academics and professional staff working in collaboration. 相似文献

This paper uses a hybrid leadership framework to examine how formal teacher leaders at the middle management level direct and facilitate staff resources for distributed pedagogical leadership. By conducting qualitative shadowing, involving video observation, field notes and stimulated recall interviews, and abductive analysis, this study demonstrates and discusses how formal teacher leaders step forward as hybrid leaders who integrate leadership into both interaction and their positional capacity. Building upon established leadership categories, the new category of leading knowledge development is discovered. The main finding is that hybrid leadership is illuminated in various leadership actions, which expand the understanding of leadership work. Conclusions drawn from the data and results suggest that hybrid leadership, in its exercise of both positional and distributed leadership, must be considered a move towards a new leadership identity. For policy and practice, this new hybrid leadership opens up a new conceptual space that is crucial to understanding how leaders recognize and contextualize their actions as a result of highly complex and dynamic work practices. 相似文献

SOA在为信息共享、应用集成、协同计算提供便利的同时,也引入了诸如权限传播控制等新型安全问题,而传统的基于身份的安全机制在应对这些新问题上显得力不从心。针对基于Web服务实现的SOA环境,分析其安全需求,引入凭证元素,设计一种基于凭证的安全框架CSFS（Credential-based Security Framework forSOA）,研究该框架下的凭证分布式管理策略。 相似文献
