企业社会责任的新思考

企业要承担社会责任虽然已经得到社会较为普遍的承认,但是存在的一个误区是,有人认为,企业承担社会责任只是为树立企业形象而长期赢利的手段,这是一种单纯工具理性的价值取向。从形而上的角度来说,还应该赋予社会责任以"价值理性"的终极意义,这种理性上的价值转向,有重要的伦理内涵。同时,要实现这种理性的转向,需要引进互惠交换机制。

But is My Resource Included? How to Manage,Develop, and Think about the Content in Your Discovery Tool

Implementing discovery tools and getting them to work with existing library services often leaves very little time for their promotion and for the thoughtful, ongoing evaluation and curation of their content. However, the expectations and experiences that users have about discovery tools are often directly related to the content and the way that content is described. In our efforts to work with vendors to resolve the underlying business issues that prevent us from having all of the metadata for our resources included in our discovery tools, we may have lost sight of our role in curating and evaluating the usefulness of the content that is already included in them.

E-learning commodity or community: Disciplinary differences between online courses

Differences in curriculum and teaching styles across disciplines in higher education courses are also evident in online courses. This study used two widely available sources of data, CMS tool usage logs and course evaluations, to analyze differences between online courses in disciplinary quadrants (hard-pure, hard-applied, soft-pure, soft-applied) at a large metropolitan university, over five years (2002 and 2007). For 2007, results revealed significant differences in tool usage between disciplines, particularly for assessment tools. Hard-pure courses used Tests and Pool tools more often than did soft-pure courses. The Document tool was used most extensively in applied courses. Data from course evaluations, for spring 2007 online courses, suggested that applied disciplines had a shorter learner–instructor transactional distance than did pure disciplines. Results suggest that over five years, e-learning in pure disciplines has become more commoditized, while e-learning in applied disciplines has become more diversified and more oriented to community practice.
