基于云计算层次架构的安全框架研究

云计算安全问题是限制云计算发展的主要问题,一直是IT 界研究的热点。介绍了云计算的特点和服务模式,总结了云计算的安全问题,最后根据云计算的层次架构探讨了解决各层次安全问题的安全策略,并在此基础上提出了一种云计算安全框架。     

面向文化传承的学科融合教育(C-STEAM):价值定位与分类框架

以传承中国优秀传统文化为目标导向的学科融合教育是一种具有本土特色的STEAM教育(即C-STEAM)。就核心价值而言,C-STEAM具有培养学生核心素养的育人价值、传承优秀传统文化的载体价值、打造区域特色文化的社会价值。立足于此,该文进一步剖析了C-STEAM教育的培养途径,从培养方式(“重过程—重结果”)和能力发展(“低阶—高阶”)两个维度出发,构建了ETIC框架,进而区分出感受体验型、技艺训练型、探究学习型、创新创作型四种典型的C-STEAM项目模式。每一类项目均有独特的内涵、特征、教学策略和相关案例,不仅可以独立使用,也可以根据需要交叉组合和迭代应用。籍此为C-STEAM项目设计提供指导性思路,为构建系统合理的C-STEAM教育奠定基础。     

Preparing for the Future: National Library of Medicine's® Project to Add MeSH® RDF URIs to its Bibliographic and Authority Records

ABSTRACT

Although it is not yet known for certain what will replace MARC, eventually bibliographic data will need to be transformed to move into a linked data environment. This article discusses why the National Library of Medicine chose to add Uniform Resource Identifiers for Medical Subject Headings as our starting point and details the process by which they were added to the MeSH MARC authority records, the legacy bibliographic records, and the records for newly cataloged items. The article outlines the various enhancement methods available, decisions made, and the rationale for the selected method.     

Navigating the turbulent waters of academia: the leadership role of programme managers

The focus of our paper is the leadership role of programme managers in the higher education sector. In particular, we highlight the complex and paradoxical nature of the programme leader’s role, and provide an insight into leadership in this challenging and dynamic environment. We identify cognitive and behavioural complexity as necessary capabilities for programme managers to ensure they can navigate the turbulent river system of academia. The Integrated Competing Values Framework describes some leadership behaviours appropriate for the programme manager’s role. We also argue how critical observation skills, reflection and self-awareness can assist programme managers to provide leadership in this uncertain environment. Our paper concludes with a discussion of areas for future research and important practical implications for universities.     

Universities and sustainable development: the necessity for barriers to change

In June 2015, the Higher Education Funding Council for England (HEFCE) proposed a lighter touch quality assessment regime that would place greater reliance on institutions' own governance arrangements. In July 2015 the Minister for Higher Education announced a Teaching Excellence Framework (TEF) parts of which appear inconsistent with HEFCE's proposals. In August the Quality Assurance Agency for Higher Education (QAA) responded to HEFCE's proposals envisaging some developments to its present quality assessment arrangements. This article analyses the key issues and principles that will supposedly govern the design of a new quality assessment regime from 2017. It proposes points of reference against which to evaluate the proposals for that new regime; these are whether the approach to review that is adopted: a) differentiates between institutions on the basis of their capacities to manage their responsibilities; b) shows the regulator's willingness to trust institutions to discharge their responsibilities (with verification) and willingness by institutions to accept their responsibilities; c) adopts an approach to risk and its management that is forward-looking and enables pre-emptive actions to forestall negative outcomes; and d) makes greater use of metrics that are interpreted by experts qualified to make judgements on academic matters.     

Creating a Research Center: Space for Collaborations and Conversations

This report describes the creation of a library research center, where a team of librarians provide flexible, convenient, and personalized research assistance to students. A research center creates a positive user experience for students and places collaboration—both among librarians and students—at its core. Next-generation reference models must provide spaces and environments for students and librarians to engage in meaningful and deep information literacy conversations as outlined in the ACRL Framework for Information Literacy for Higher Education.     

The Divide and Conquer Exercise: Finding the Essence of Difficult Readings

Objective: In this exercise, students collectively summarize a long and perhaps difficult reading into a shorter, more condensed version of itself; in the process, students experience the virtues of teamwork (the divide and conquer approach), gain valuable reading and note-taking skills, and collectively distill the essence of a reading in class.

Courses: This exercise works best in any course with theoretical or complex readings assigned to students as outside reading, e.g., introductory courses in communication, communication theory, special topics in communication; the exercise requires 20–40 students.
