This article addresses the problem of estimating the proportion Pi[subscript S] of the population belonging to a sensitive group using optional randomized response technique in stratified sampling based on Mangat model that has proportional and Neyman allocation and larger gain in efficiency. Numerically, it is found that the suggested model is…

Measures of student disadvantage--or risk--are critical components of equity-focused education policies. However, the risk measures used in contemporary policies have significant limitations, and despite continued advances in data infrastructure and analytic capacity, there has been little innovation in these measures for decades. We develop a new…

In recent decades, school performance ranking (or 'league table') have become a common feature of many education systems in the world. The ranking is usually published by government and news agencies in an attempt to measure and compare the relative performance of individual schools against a number of criteria, including academic performance.…

Purpose: The purpose of this paper is to provide an empirical comparison of two measures of school success -- a value-added assessment system and the federally-mandated system of adequate yearly progress (AYP) -- to identify highly effective urban schools in the USA and to explore the predictive relationship between evidence-based decision-making…

The procedures required to obtain the approximate posterior standard deviations of the parameters in the three commonly used item response models for dichotomous items are described and used to generate values for some common situations. The results were compared with those obtained from maximum likelihood estimation. It is shown that the use of…

Considers electronic commerce as a paradigm shift, or a disruptive innovation, and presents an analytical framework based on the theories of transaction costs and switching costs. Topics include business transformation process; scale effect; scope effect; new sources of revenue; and e-commerce value creation model and strategy. (LRW)

Typical prevailing task analysis really is skill analysis whose product is a set of generic tasks considered to exhaust or sufficiently sample a skill domain. This approach yields tasks as the base entities of analysis; any understanding of interrelations of structures in the skill architecture in consequence must occur--if at all--above the level…

The intent of this paper is to generalize the min and max clustering procedures in such a way that the assumption of a symmetric similarity measure is unnecessary. (Author)

Describes an instructional design review process in which peers offer feedback through "structured walkthroughs." Discusses types of reviews, guidelines, and success factors, and summarizes a formal peer review structure developed and tested at Hewlett-Packard Company. Two tables present advantages and disadvantages of types of design…

Analyzes relevance assessments of topical descriptors for bibliographic records for two dimensions: (1) a vertical conceptual hierarchy of broad to narrow descriptors, and (2) a horizontal linkage of related terms. The data were analyzed for a semantic distance and semantic direction effect as postulated by the Semantic Distance Model. (Author/LRW)

Discusses training evaluation and shows how an abbreviated form of Kirkpatrick's four-level evaluation model can be used effectively to evaluate multimedia-based manufacturing training. Topics include trends in manufacturing training, quantifying performance improvement, and statistical comparisons using the Mann-Whitney test and the Tukey Quick…

Several methods for the analysis of three-way data (data classified three ways) are described and shown to be variants of principal components analysis of the two-way supermatrix in which each two-way slice is strung out into a column vector. Direct fitting and fitting derived data are considered. (SLD)

Describes a study that computed the low performance standards for queries in 17 test collections. Predicted by the hypergeometric distribution, the standards represent the highest level of retrieval effectiveness attributable to chance. Operational levels of performance for vector-space and other retrieval models were compared to the standards.…

Presents the results of a comparative evaluation of four CD-ROM retrieval software packages using the Revised Richards-Brown CD-ROM Software Evaluation Model. CD Answer, SPIRS, KAware2, and ROMware are evaluated, and results indicate that SPIRS and CD Answer are the favored packages. (LRW)

A survey of 100 manufacturing companies in the United Kingdom identified evaluation methods for and barriers to effective training program implementation. Most felt their programs did not reach full potential in terms of higher productivity, performance, and improved quality. A program assessment model and policy recommendations were proposed.…
