The digit naming speed test: Its power and incremental validity in identifying children with specific reading disabilities

This paper presents two studies, both of which address the question of whether a test that measures the automaticity with which digits can be named could be useful as part of a diagnostic battery to assess reading disabilities. In the first study, the Digit Naming Speed Test significantly differentiated elementary-school boys who were disabled readers from age-matched boys reading at appropriate grade levels, correctly classifying 83.3% of the children. In the second study, the Digit Naming Speed Test accounted for a significant portion of the word recognition variance of nondisabled readers over and above that portion accounted for by general intelligence as measured by the WISC-R. Taken together, these studies indicate that the Digit Naming Speed Test has the potential to contribute significantly to the diagnostic process.     

Creating a more inclusive journal: the Journal of the Medical Library Association's evolving process for selecting editorial board members

The Journal of the Medical Library Association (JMLA) selects new editorial board members every year. In the spring of 2021, JMLA used a new process for reviewing and selecting applicants for the limited number of open editorial board positions. This reevaluation of the selection process was spurred by a desire to create a more diverse and representative board. Changes to the procedures for selecting new editorial board members included having an open call for editorial board members, creating an application form, creating a selection committee to screen applicants, creating a form for the selection committee to extract data from applications, and creating a two-step process for screening and then selecting board members. As part of construction of this new process, areas for continued improvement were also identified, such as refining the application form to allow more specific answers to areas of interest to the selection committee. The newly created selection process for editorial board members constitutes a significant change in JMLA processes; however, more can be done to build on this work by further refining the selection process and ensuring that new members are selected in a transparent and streamlined manner.     

Discrepancies between IQ and index scores for a clinical sample of students: Useful diagnostic indicators?

Discrepancies between IQ and Index scores on the WISC-111 were investigated for a sample of students with SLD (n = 202), with MR (n = 115), and evaluated but not classified (n=159). Mean Verbal and Performance IQ discrepancies, though significantly different for each sample, were smaller than those reported in the WISC-III manual for the normative sample. Similarly, the Index score comparisons indicated differential functioning for the three samples, with the exception of the Verbal Comprehension and Freedom from Distractibility Index discrepancy. Moreover, the Performance IQ was higher than the Verbal IQ for all three samples. Consistent with the WISC-R literature, discrepancies between Verbal and Performance IQs and higher Performance than Verbal IQs are not diagnostic indicators of abnormalities.     

WISC-R examiner errors: Cause for concern

While errors on the WISC-R are conceived primarily in terms of internal consistency and stability over time, examiners make mistakes that contribute to the inaccuracy of test scores. Studies to date mainly have investigated general scoring errors, rather than specific items most prone to error. Investigation of graduate students' test protocols indicated numerous scoring and mechanical errors that influenced the Full Scale IQ scores on two-thirds of the protocols. Particularly prone to error were Verbal subtests of Vocabulary, Comprehension, and Similarities. More importantly, specific items on subtests in which numerous mistakes occurred were noted, as well as the most likely type of error for each item. These findings have implications for the education and training of assessment specialists.     

Context-Sensitive Instructional Design Models: A Response to Design Research,Studies, and Criticism

Instructional design, as it is traditionally conceptualized, is being challenged on several fronts, through surveys of design practice, cross-disciplinary studies of design practice, and practical criticism focusing on issues of design models' flexibility and efficiency. Collectively these challenges raise questions about the viability of the instructional design enterprise. This paper reviews these challenges and attempts to respond by offering alternative approaches to instructional design.     

On-the-Job Training: Prescriptions and Practice

This article discusses the status of workplace training in the United States, describes a model of how to conduct effective on-the-job training, and presents the results of a questionnaire based on a model designed to assess on-the-job training practices aboard Navy ships. The model views the on-the-job trainer as a coach who guides the trainee through a task using three steps: 1) assessment, 2) training, and 3) evaluation. The questionnaire was sent to over 5,000 shipboard supervisors; 2,321 responded. Results indicate that nearly 50% of the Navy supervisors who responded are not as effective as they could be. The implications of these findings for the civilian workplace are discussed.     

CERN: Past performance and future prospects: II. The scientific performance of the CERN accelerators

In a series of three papers, we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organization for Nuclear Research (CERN) over the period since 1960, and to assess the future prospects for CERN and its users during the next ten to fifteen years.We concerned ourselves in a previous paper (Paper 1 - Martin and Irvine [51] with the position of the CERN accelerators in world high-energy physics relative to those at other large laboratories working in the field. We dealt primarily with the period from 1969 to 1978, and attempted to establish how the experimental output from the three principal CERN accelerators, taken as a whole, compared with that from other major facilities. In undertaking this comparative evaluation, we drew on the method of “converging partial indicators” used in previous studies of three Big Science specialties.In contrast, this paper (Paper II) focuses in detail on the scientific performance of each of the CERN accelerators taken individually. In particular, it asks, first, how the outputs from the CERN 28 GeV (giga or billion electron-volts) Proton Synchrotron compare with those from a very similar 33 GeV American accelerator at Brookhaven National Laboratory over the past two decades? Second, how great have been the experimental achievements of the Intersecting Storage Rings in world terms? And, third, how do the outputs from the CERN 400 GeV Super Proton Synchrotron and from a rival American machine at Fermi National Accelerator Laboratory compare? Attempts are then made to identify the main factors responsible for determining the relative scientific performance of each CERN machine.These factors are of relevance to the subject of a third paper (Paper III - Martin and Irvine [52]) which sets out to assess the future prospects for CERN and in particular for LEP, the large electron-positron collider scheduled for completion in the latter part of the 1980s. What are the construction requirements (financial and technical) associated with LEP, and how easily will they be met? How does the scientific potential of LEP compare with that of other major accelerators under construction around the world? And, in the light of the previous record of the CERN accelerators, to what extent is this potential likely to be realized? The paper concludes with a discussion of the extent to which predictive techniques can be utilized in the formulation of scientific priorities, and of the problems in current science policy-making that such techniques might help address.
