A Squatter on the Fourth Estate: Google News

SUMMARY

Buoyed by its brand name, Google News has grown from its beta stage into a popular news site with a significant share of the Internet market for “Current Events and Global News.” The success of Google News raises questions about the nature of news and even the desirability of Google's presenting news. Where does Google News fit into the myriad news resources available on the Internet and in libraries? How does Google News work? Is Google News an effective source for news research? How will Google News stand up to its competition, in particular a new wave of community news sites?

Learning to Love Your Discovery Tool: Strategies for Integrating a Discovery Tool in Face-To-Face,Synchronous, and Asynchronous Instruction

Some librarians embrace discovery tools while others refuse to use them. This lack of consensus can have consequences for student learning when there is inconsistent use, especially in large-scale instruction programs. The authors surveyed academic librarians whose institutions have a discovery tool and who teach information literacy classes in order to identify barriers to using them and to develop strategies to effectively integrate them into instruction. The authors used the survey results and recent studies on the research habits of undergraduates to propose strategies for integrating the discovery tool at the programmatic level in a more meaningful and sustainable way.     

From Horse-Drawn Wagon to Hot Rod: The University of California's Digital Image Service Experience

SUMMARY

This article proposes that a viable approach archivists might consider to meet increasing demands for access to digital images with functional presentation tools is to develop a reciprocal partnership with a digital library. The University of California's experience with the federation of licensed and UC-owned digital image collections is summarized to illuminate core issues related to collection development, system functionality, and patron usability. The resulting UC Image Service is then examined against a backdrop of comparable digital imaging projects with reflections on strategies and intersections. The range of business models and approaches to digital image collection access and developing image management and presentation tools highlight the unprecedented opportunities digital technology provides for moving archives towards an integrated environment through collaborative action.     

Promise Fulfilled? An EBSCO Discovery Service Usability Study

Discovery tools are the next phase of library search systems. Illinois State University's Milner Library implemented EBSCO Discovery Service in August 2010. The authors conducted usability studies on the system in the fall of 2010. The aims of the study were twofold: first, to determine how Milner users set about using the system in order to better inform customization choices, which in turn would create better search experiences, and second, to find out whether discovery tools fix the problems of federated search. With federated search technology, users often felt frustrated by the search experience. Some reasons for the frustration included a desire for better ways to determine the relevancy of search results and for more information about the material included in the records. The authors determined that while many federated search problems were solved, some issues persisted. Overall, the move to EBSCO Discovery Service at Milner Library has been a positive experience for its users.     

数控机床螺距误差补偿原理及方法

数控机床的传动机构一般均为滚珠丝杠副,滚珠丝杠副在生产制造和装配过程中都存在一定的误差,对机床轴线滚珠丝杠的螺距误差进行补偿,可提高机床的定位精度和重复定位精度,从而提高数控机床的加工精度.

The planning illusion: does active planning of a learning route support learning as well as learners think it does?

Is actively planning one’s learning route through a learning domain beneficial for learning? Moreover, can learners accurately judge the extent to which planning has been beneficial for them? This study examined the effects of active planning on learning. Participants received a tool in which they created a learning route themselves before accessing learning material and, for comparison, also worked with a tool in which the route was planned automatically. Eighty-three participants participated in learning sessions with both tools over two topics in statistics. Both tools were found to influence the learning process. However, results indicate inconsistency between participants’ judgement of the relative effectiveness of the two types of tools and their actual learning outcomes. Although participants thought they had learned more when they actively created a plan themselves, knowledge tests showed no differences on performance between actively planning a learning route or receiving it ready-made.
