The Research Associateship program of the Joint Committee on Powder Diffraction-International Centre for Diffraction Data (JCPDS-ICDD, now known as the ICDD) at NBS/NIST was a long standing (over 35 ...years) successful industry-government cooperation. The main mission of the Associateship was to publish high quality x-ray reference patterns to be included in the Powder Diffraction File (PDF). The PDF is a continuing compilation of patterns gathered from many sources, compiled and published by the ICDD. As a result of this collaboration, more than 1500 high quality powder diffraction patterns, which have had a significant impact on the scientific community, were reported. In addition, various research collaborations with NBS/NIST also led to the development of several standard reference materials (SRMs) for instrument calibration and quantitative analyses, and computer software for data collection, calibration, reduction, for the editorial process of powder pattern publication, analysis of powder data, and for quantitative analyses. This article summarizes information concerning the JCPDS-ICDD organization, the Powder Diffraction File (PDF), history and accomplishments of the JCPDS-ICDD Research Associateship.
Two methods for comparing impact factors and citation rates across fields of science are tested against each other using citations to the 3,705 journals in the Science Citation Index 2010 (CD‐Rom ...version of SCI) and the 13 field categories used for the Science and Engineering Indicators of the U.S. National Science Board. We compare (a) normalization by counting citations in proportion to the length of the reference list (1/N of references) with (b) rescaling by dividing citation scores by the arithmetic mean of the citation rate of the cluster. Rescaling is analytical and therefore independent of the quality of the attribution to the sets, whereas fractional counting provides an empirical strategy for normalization among sets (by evaluating the between‐group variance). By the fairness test of Radicchi and Castellano (), rescaling outperforms fractional counting of citations for reasons that we consider.
The purpose of this study was to compare the effectiveness of both an interactive, multimedia CD-ROM and a traditional lecture for teaching oral medication administration to nursing students. A ...randomized pretest/posttest experimental design was used. Forty-two junior baccalaureate nursing students beginning their fundamentals nursing course were recruited for this study at a large university in the midwestern United States. The students ranged in age from 19 to 45. Seventy-three percent reported having average computer skills and experience, while 15% reported poor to below average skills. Two methods were compared for teaching oral medication administration--a scripted lecture with black and white overhead transparencies, in addition to an 18-minute videotape on medication administration, and an interactive, multimedia CD-ROM program, covering the same content. There were no significant (p < .05) baseline differences between the computer and lecture groups by education or computer skills. Results showed significant differences between the two groups in cognitive gains and student satisfaction (p = .01), with the computer group demonstrating higher student satisfaction and more cognitive gains than the lecture group. The groups were similar in their ability to demonstrate the skill correctly. Importantly, time on task using the CD-ROM was less, with 96% of the learners completing the program in 2 hours or less, compared to 3 hours of class time for the lecture group.
This article discusses the use of OCLC's QuestionPoint service for managing electronic publications and other items that fall outside the scope of OCLC Library's OPAC and Web resources pages, yet ...need to be "put somewhere." The local knowledge base serves as both a collection development tool and as a virtual vertical file, with records that are easy to enter, search, update, or delete. Beyond its usefulness as a system to receive, manage, and answer inquiries, QuestionPoint is providing a way to facilitate access to online resources that addresses the particular needs of OCLC Library's constituency. It is fast and easy to use: a standard part of the daily workflow. It enables direct links to sources and accommodates tagging those sources with the names of people and projects, as well as subjects. It serves as part of the library's collection management and selection system.
macro- and microstructural information. In order to evaluate the methods which lexicographers employ to improve dictionary accessibility, the concept of guide structures was introduced by Hausmann ...and Wiegand (1989). Since the appearance of that article, various academics have written articles and read papers on guide structures in print dictionaries, but few studies have focussed on the tremendous potential of guide structures in electronic dictionaries. In this article it will be shown that electronic dictionaries add dimensions to the implementation of guide structures not possible in print versions. The role of two of the guide structures in the transfer of infonnation in CD-ROM dictionaries will be discussed. The access and mediostructures of the Microsoft Encarta World English Dictionary and the Elektroniese Handwoordeboek van die Afrikaanse Taal will be analysed and critically evaluated to illustrate the advantages of electronic dictionaries over print dictionaries and the urgent need for metalexicographical discussion of this publication medium.

Opsomming: Gidsstrukture in CD-ROM-woordeboeke, met spesifieke verwysingna EWED en ELHA T. Die sukses van modeme woordeboeke hang grootliles af vandie toeganklikheid van hulle makro- en mikrostrukturele inligting. Hausmann en Wiegand (1989)het die konsep van gidsstrukture ingevoer om die metodes te evalueer wat leksikograwe gebruikom woordeboektoeganklikheid Ie verbeter. Sedert hierdie artikel verskyn het, het verskeie akademic:i artikels gepubliseer en referate gelewer oor gidsstrukture in gedrukte woordeboeke, maarmin studies het gefokus op die geweldige potensiaal van gidsstrukture in elektroniese woordeboeke.In hierdie artikel sal dit getoon word dat elektroniese woordeboeke geleenthede vir dieimplementering van gidsstrukture skep wat rue in gedrukte weergawes moontlik is rue. Twee'vandie gidsstrukture se rol in die oordrag van inligting in CD-ROM-woordeboeke sal bespreek word.Die toegang- en mediostrukture van die Microsoft Encarta World English Dictionary en die ElektronieseHandwoordeboek van die Afrikaanse Taal sal onHeed en krities geanaliseer word, om die voordele van elektroniese bo gedrukte woordeboeke en die dringende behoefte' aan die metaleksikografiesebespreking van hierdie publikasiemedium te iUustreer.

Ameloblastoma is a benign locally aggressive infiltrative odontogenic lesion. It is characterized by slow growth and painless swelling. The treatment for ameloblastoma varies from curettage to en ...bloc resection, and the reported recurrence rates after treatment are high; the safety margin of resection is important to avoid recurrence. Advances in technology brought about great benefits in dentistry; a new generation of computed tomography scanners and 3-dimensional images enhance the surgical planning and management of maxillofacial tumors. The development of new prototyping systems provides accurate 3D biomodels on which surgery can be simulated, especially in cases of ameloblastoma, in which the safety margin is important for treatment success. A case of mandibular follicular ameloblastoma is reported where a 3D biomodel was used before and during surgery.
There is plenty of paper-based material on this subject, but a teaching package with a multimedia format can only improve learning. When inserted into the CD Rom drive, the title appears and displays ...a prominent "click to start" button that allows web browsers entry into the learning package. The target audience has not been clearly defined apart from the obvious-students who want to learn about the assessment of children with disabilities.
