Creating Radioactive MARC Records and Z Queries Using the MARCdocs Database

Description: This document describes how the authors can extend a relational database of MARC documentation to store the appropriate information that will support the automatic generation of the special, diagnostic MARC records the authors will call radioactive MARC (RadMARC) records. The information contained in the database will also support the generation of the Z queries used in the interoperability testing.

Indexing Guidelines to Support Z39.50 Profile Searches

Description: This document provides guidelines for indexing MARC 21 records to support a set of searches using Z39.50. The Z39.50 Interoperability Testbed Project (Z-Interop) uses these guidelines to index the 400,000 MARC 21 records that comprise the Z-Interop reference implementation of the Z39.50 server and online catalog.

Z-Interop Interoperability Testing Policies and Procedures: Phase 1 Testing

Description: This document provides an overview and the details of policies and procedures of the Z39.50 Interoperability Testbed Project (referred to as Z-Interop). Specifically, the document lays out the responsibilities and obligations of the Z-Interop testbed and the organizations that participate in interoperability testing. For purposes of this document, Z-Interop staff refers to all members of the Z39.50 Interoperability Testbed Project. Z-Interop participant refers to an individual or organization who tests its Z39.50 client or Z39.50 server through the Z39.50 Interoperability Testbed.

News photography image retrieval practices: Locus of control in two contexts.

Description: This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed with phenomenography. The survey data demonstrated that most participants prefer searching by events taking place in the photograph, objects that exist in the photograph, photographer-provided keywords, and relevant metadata, such as the date the picture was taken. They also prefer browsing. Respondents had mixed opinions about searching by emotions elicited in a photograph, as well as the environmental conditions represented in a photograph. Participants' lowest-rated methods included color and light, lines and shapes, and depth, shadow, or perspective. They also expressed little interest in technical information about a photograph, such as shutter speed and aperture. Interview participants' opinions about the search methods reflected the survey respondents' views. They discussed other aspects of news photography as well, including the stories told by the pictures, technical concerns about digital photography, and digital archiving and preservation issues. These stated preferences for keyword searching, browsing, and photographer-provided keywords illustrate a desire for a strong internal locus of control in digital photograph archives. Such methods allow users more control over access to their photographs, while the methods deemed less favorable by survey participants offer less control. Participants believe they can best find their photographs if they can control how they index and search for them. Therefore, it would be useful to design online photograph archives that allow users to control representation and access. Future research possibilities include determining the preferences of other image retrieval system ...

Techniques for Improving Uniformity in Direct Mapped Caches

Description: Directly mapped caches are an attractive option for processor designers as they combine fast lookup times with reduced complexity and area. However, directly-mapped caches are prone to higher miss-rates as there are no candidates for replacement on a cache miss, hence data residing in a cache set would have to be evicted to the next level cache. Another issue that inhibits cache performance is the non-uniformity of accesses exhibited by most applications: some sets are under-utilized while others receive the majority of accesses. This implies that increasing the size of caches may not lead to proportionally improved cache hit rates. Several solutions that address cache non-uniformity have been proposed in the literature. These techniques have been proposed over the past decade and each proposal independently claims the benefit of reduced conflict misses. However, because the published results use different benchmarks and different experimental setups, (there is no established frame of reference for comparing these results) it is not easy to compare them. In this work we report a side-by-side comparison of these techniques. Finally, we propose and Adaptive-Partitioned cache for multi-threaded applications. This design limits inter-thread thrashing while dynamically reducing traffic to heavily accessed sets.
