Abstract:
The present study sought to determine the utility of the unweighted sum as an alternative to conjoint measurement in forming a workload composite measure with the Subjective Workload Assessment Technique (SWAT). The data from a simulator study designed to identify pilot workload associated with alternative cockpit configurations in a night air interdiction mission were reanalyzed using a percentage measure (SUMPCT) based on the unweighted sum of the three SWAT rating scales. Results indicated that the CONJOINT and SUMPCT workload composites were highly correlated and were equally sensitive to

Abstract:
Health scales or indices are composite tools aiming to measure a variety of clinical conditions, behaviors, attitudes and beliefs that are difficult to be measured quantitatively. During the past years, these tools have been extensively used in cardiovascular disease prevention. The already proposed scales have shown good ability in assessing individual characteristics, but had moderate predictive ability in relation to the development of chronic diseases and various other health outcomes. In this review, methodological issues for the development of health scales are discussed. Specifically, t

Abstract:
The present study compared three subjective workload measurement techniques—a unidimensional scale (UW) and two mutidimenional scales (TLX and ModSWAT)–using a continuous memory task. ModSWAT is a technique that uses the sum of the SWAT dimensions to form the workload composite rather than the standard conjoint measurement procedure. Both weighted and unweighted workload measures were obtained for the two multidimensional scales. The paired-comparison technique used by TLX was employed to weight the three SWAT dimensions. For both multidimensional scales, weighting context was also varied. Pai

Laminated composites are materials with complex architecture made of continuous fibers embedded within a polymeric resin.

Abstract:
This chapter presents a general approach to assessing the reliability of measurement of survey questions—those in common use in many surveys. The approach, which relies on a robust set of longitudinal design requirements, applies the quasi-Markov simplex model to multi-wave data in the evaluation of measurement errors for survey questions. Under particular assumptions, this model produces a set of estimates that conform to the psychometric definition of measurement reliability, defined as the ratio of true variance to observed variance. These models attribute some of the over-time inconsistency in measurements to unreliability and some to true change. This strategy rejects traditional notions of reliability that rely on internal consistency estimates for composite variables, as well as the simple test–retest approach to estimating reliability. Rather, the emphasis is on the separation of unreliability from true change in observations made over time. The importance of meeting several design requirements for using these over-time statistical models is also emphasized. These include the use of large-scale panel studies representative of known populations, with a minimum of three waves of measurement, separated by lengthy re-interview intervals, and limited to exactly replicated questions over the multiple waves. Results are presented from several three-wave panel studies that have employed this design, which provide evidence for the utility of the approach in the evaluation of the quality of survey measurement with respect to question content, context, and form.

Abstract:
Low-velocity impact events occurring over the span of a few milliseconds cause changes in composite structures through relaxation and delamination propagation which manifest themselves over the span of several seconds. Changes in embedded fiber Bragg grating sensor response allow the damage in the composite structure to be measured in lieu of simply analyzing the impact event itself. By observing the damage progression and subsequent failure of the sample, the sensor signal response can thus be used to predict the lifetime of the structure.
