CATS EYES adjustment procedures by Joseph C Antonio( Book )

3 editions published in 1993 in English and held by 162 WorldCat member libraries worldwide

Night vision goggles (NVGs) have been employed in a variety of aircraft for over twenty years. However, only recently has their application begun in fixed-wing fast movers. Research accomplished by the Night Vision Programs Office at the Aircrew Training Research Division of the USAF Armstrong Laboratory demonstrated the loss of NVG performance resulting from improper adjustments. This report describes correct adjustment procedures for the F4949 NVG system. The procedures described were developed so aircrews could take advantage of the adjustments available on the NVGS. Additionally, image descriptions are given to help aircrews evaluate NVG performance. Information on the proper equipment/space needed for proper evaluation is also included.

Integrated Maintenance Information System : user field demonstration and test executive summary by Donald L Thomas( Book )

2 editions published in 1995 in English and held by 161 WorldCat member libraries worldwide

This Executive Summary summarizes the results of a field test and demonstration of the Integrated Maintenance Information System (IMIS). The IMIS project was an advanced development demonstration project which developed and field tested the technology to provide the maintenance technician with the capability to access all of the technical information (interactive electronic technical manuals, interactive diagnostics instructions, work orders, supply availability and ordering, historical data, training material, etc.) required to maintain aircraft via a single, integrated system, regardless of the source of that information. In the final phase of the project, an IMIS Demonstration System was developed and tested. In the field test, the performance of technicians on troubleshooting tasks when using the IMIS was compared with their performance on comparable tasks when using the paper technical orders. Test results indicated that technicians were able to perform the tasks significantly faster, used fewer parts, and made fewer serious errors when using the IMIS. In addition, the test indicated that, when using the IMIS, non-specialist (crew chief) technicians could perform the tasks as effectively as the specialists

Smooth eye movement response to complex motion sequences by Julie Mapes Lindholm( Book )

1 edition published in 1996 in English and held by 96 WorldCat member libraries worldwide

To examine the spatiotemporal properties of the motion sensors for the smooth pursuit system, we presented horizontal motion sequences in which successive target displacements were in accord with a composite waveform representing the sum of a constant velocity ramp and a sawtooth. The sequences differed in global velocity (GV = ramp velocity = 0 or 4 deg/sec), local velocity (LV = ramp velocity + sawtooth velocity = -8 or -4 deg/sec, for GV =0, and -8, -4,0, 8, 12 deg/sec, for GV = 4), and local-segment duration (12 values between 67 and 700 msec). When the duration of a local-velocity segment was relatively short C less than or equal to 133 msec, for GV =4 deg/sec; less than or equal to 200 msec, For GY =0 deg/sec), mean pursuit velocity matched the GV. As the segment duration increased, mean pursuit velocity shifted gradually toward the LV. Changes in cumulative saccadic amplitude mirrored the changes in smooth pursuit velocity. The spatiotemporal-frequency spectra of the motion sequences suggested that the pursuit system responded in accord with the drift velocities of very low spatial frequencies. The spectra of the space-time retinal images suggested that pursuit was maintained not by the absence of retinal image motion but by the presence of appreciable spectral energy for components with a drift velocity of approximately zero
Beyond word processing : using an interactive learning environment to teach writing by Patricia Ann Carlson( Book )

1 edition published in 1996 in English and held by 95 WorldCat member libraries worldwide

This study examines whether computer-aided instruction that explicitly models the process of composing for basic writers is more effective than traditional classroom instruction. Three objectives guided the research: to determine the basic quality of essays from the treatment and the control group using standard, holistic rating methods; to infer cognitive development by measuring improvement along four separate measures using an analytic scale; to determine whether initial aptitude was a factor in performance differences. Eight-hundred and fifty-two eighth-grade English students (423 in the control group and 429 in the treatment group) completed a 40-minute transactional writing sample at the beginning and at the end of a 16-week semester. The results show that the group using a computerized cognition facilitator outperformed the group taught only in the traditional classroom both on the holistic and on the analytical measures. Additionally, when the population was partitioned to reflect initial ability the treatment group in the lower segment showed marked improvement, whereas the high-end segment of the treatment group produced no significant gain. When partitioned in the same manner, the high-end for the control group degraded in performance, while the lower-end control improved both on the holistic and the analytic measures

A comparison and integration of three training evaluation approaches : effectiveness, utility, and anticipatory evaluation of training by George M Alliger( Book )

1 edition published in 1996 in English and held by 86 WorldCat member libraries worldwide

This report provides a brief overview of three methods, or general approaches, to judging the usefulness of training. The first method or approach is the traditional evaluation approach of training effectiveness evaluation. This method or approach centers on estimations of training effect size and the determination of the statistical significance of those training effects. Thus, in this first category standard pre(post analyses and control group comparisons are included. Next traditional training utility analysis, or training utility evaluation is reviewed here, costs and benefits of training are always contrasted in some way in determining traditional utility analysis. This branch of evaluation traces its roots back to Brogden & Taylor (1950), who discussed the need to examine the dollar criterion. Finally, anticipatory training evaluation is discussed Anticipatory training evaluation examines what kinds of training will have the greatest effectiveness and utility, given a variety of parameters and choices. The primary tool in anticipatory evaluation is Multi-Attribute Utility analysis (MAU). As opposed to training effectiveness and training utility evaluation, MAU is designed explicitly as a decision tool. It can be used most effectively as an anticipatory evaluation, the results of which facilitates planning for training. A detailed example of the development and application of MAU is described in this report, since it is the least well known of the three approaches to researchers and practitioners in the training are. In explicating this expanded view of training evaluation, this report attempts to represent state-of-the-art understanding and research; thus current issues like risk and uncertainty in input and output evaluation and utility indices, and problems in transfer of learned skills to the job, are addressed in appropriate contexts
A comparitive assessment of alternative models of factors perceived to contribute to success in international assignments by Winfred Arthur( Book )

1 edition published in 1996 in English and held by 86 WorldCat member libraries worldwide

Using Campbell's (1990) theory of job performance, the present study sought to identify the factors underlying the job performance of international assignees and their relative importance. Four alternative models of international assignee job performance were also evaluated. Subjects were 338 international assignees from diverse countries (nationality) and organizations, assigned to diverse countries, and performing diverse jobs. Although eight factors were identified as hypothesized, the content and labels of these factors differed from those postulated by the theory. The eight job performance factors in descending order of importance were Flexibility, Family Situation, Management/Administration, Integrity, Effort, Tolerance, Cross-Cultural Interest, and Openness. Factor importance ratings were also influenced by position (managerial/non-managerial status), organizational type, international assignees' nationality, the country to which they were assigned, and cultural distance (similarity between nationality and assigned country). Finally, although military personnel were excluded from this study since they typically are assigned to places where their culture is present in some form (e.g., they are assigned to a U.S. military base), the factors identified as being important for international assignees, in general, should also be considered as part of the assignment process and in job design and redesign for military personnel in foreign postings. The importance of these factors should also be considered when developing the cultural training and education programs for military personnel prior to their assignment within non-US host countries. The likelihood that these factors may serve as predictors of the success of a military member in a foreign assignment in a manner similar to that of non-military personnel must be considered and addressed
Transferability of skills : convergent, postdictive, criterion-related, and construct validation of cross-job retraining time estimates( Book )

1 edition published in 1997 in English and held by 86 WorldCat member libraries worldwide

The purpose of this project was to validate estimates of cross-job transferability of skills among enlisted speciality in the US Air Force (USAF). A sample of retrainees, their supervisors and peers, and a sample of nonretrainees were surveyed on a Transferability of Skills Questionnaire (TSQ), which included that (a) cross-job retraining time estimates (XJRTEs) exhibited significant convergent validity with other AFS-level predictors of retraining ease (job learning difficulty and cross-AFS differences in aptitude requirements), (b) XJRThs exhibited some postdictive validity when evaluated against Airman Retraining Program Survey retraining ease criteria, (c) XJRThs exhibited significant criterion-related validity against time-to-proficiency (but not job performance) criteria, and (d) although retraining climate predicted some aspects of retraining success, it did not consistently moderate the XJRTE-training success relationship as was predicted. Results are discussed in terms of implications for USAF restructuring and retraining policy
Design considerations for an on-screen keyboard by Laurie Larsen Quill( Book )

1 edition published in 1996 in English and held by 86 WorldCat member libraries worldwide

This study tested & evaluated 3 on-screen keyboard arrangements with indirect input devices. in this study, finger placement & non-finger placement typists provided data for Stimulus Type (word vs. non-words), input Devices (mouse vs. arrow keys), & Keyboard Arrangements (i-row alphabetical, 3-row alphabetical, & QWERTY). Data were collected on two movement tasks & a typing task. in the typing task, the user typed a given Stimulus Type using one of the On- Screen Keyboard Arrangements & input devices. The movement tasks served as controls for movement time in the typing task. The QWERTY keyboard arrangement resulted in the'fastest overall input times & was the most preferred arrangement overall. Analysis of the interaction between input Device & Keyboard Arrangement for the unadjusted typing task times (before removing movement time) showed that when movement time was included, input times for the 1-Row Alphabetical were slower than the QWERTY for the Mouse condition; whereas, within Arrow Key condition, input times for the 1-Row Alphabetical & QWERIY were equivalent. This change in relative performance under the 1- Row Alphabetical arrangement for the Mouse condition can be simply attributed to movement time. After statistically removing the effects of movement time from the typing task, the I-Row Alphabetical arrangement was equivalent to the QWERTY for both input device. Conclusions suggest potential inefficiency of movement control when using the Mouse with the 1-Row Alphabetical arrangement Design which limit vertical movement of the indirect input device could provide more efficient movement time results with the 1-Row arrangement, thereby improving overall performance when using the 1-Row On-Screen Keyboard arrangement
Integrated Model Development Environment (IMDE) support for Air Force logistics by Todd Carrico( Book )

1 edition published in 1996 in English and held by 86 WorldCat member libraries worldwide

This report documents research performed for the Integrated Model Development Environment (IMDE) by Armstrong Laboratory, Logistics Research Division, Wright-Patterson AFB, Ohio. IMDE is a simulation development system designed to demonstrate how an object oriented modeling approach embedded within a graphical user interface could make large-scale logistics models easier to develop and less expensive to maintain, as well as improving configuration control, data analysis, collaborative development, and model reuse. The IMDE system was demonstrated through the development of an object-oriented fighter airbase logistics model. A significant achievement in the effort was the automated conversion of Logistics Composite Model (LCOM) into IMDE objects
Applying neural networks to Air Force personnel analysis by Vince L Wiggins( Book )

3 editions published in 1992 in English and held by 85 WorldCat member libraries worldwide

The principal objective of this task involved evaluating artificial neural networks for application to personnel modeling by examining areas representative of many personnel models. The four areas chosen were airmen re- enlistment, the determinants of reenlistment, and the effects of policy levers; pilot training and more specifically the likelihood of candidates successfully completing Undergraduate Pilot Training; projection of aggregate time series personnel flow rates; and productive capacity of airmen as it relates to aptitude and experience. In addition, the productive capacity analysis was expanded into a working computer prototype allowing the user to examine the effect of changing aptitude/experience mixes on productive capacity. Performance was compared against traditional techniques such as regression analysis.

Feasibility of using individual differences in emotionality as predictors of job performance( Book )

1 edition published in 1998 in English and held by 85 WorldCat member libraries worldwide

In this report, the feasibility of using knowledge about emotions and emotionality to improve personnel management practices and increase the understanding and prediction of performance and other organizational outcomes is addressed. The report is divided into several sections. First, the definitions of emotions and emotionality are discussed. Second, existing literature dealing with emotions and emotionality in work settings is reviewed. Third, the authors develop a model of how individual differences in emotional expression, combined with organizational, occupational and job demands, influence the way individuals react to triggering stimuli that set off emotions and affect job behaviors and performance. Fourth, the methods used to measure emotions and emotionality are discussed and a variety of self-report measures are reviewed. Fifth, the authors summarize their view that it is indeed feasible for measures of emotion and emotionality to show incremental validity in predicting job behaviors, performance and other work outcomes. Finally, the authors discuss a number of applied reasons for studying emotionality in organizations
Image update rate can affect the perceived speed of simulated self-motion by Julie Mapes Lindholm( Book )

1 edition published in 1996 in English and held by 85 WorldCat member libraries worldwide

The update rate of an image generator affects the spatiotemporal representation of a time-varying scene and thus, potentially, an observer's percept during observation of the display image. In the first part of this report, we discuss image generation technology and sampling theory, and we present an analysis of the temporal frequencies in a space-time image representing constant-velocity, constant-altitude flight over a flat, textured terrain. In the second part, we report the results of two experiments in which a two-alternative, forced-choice method of constant stimuli was used to investigate the effects of image update rate (30 Hz vs 60 Hz) on the perceived speed of self motion. We found that perceived speed was higher with the lower update rate when the original image, internal to the computer, contained very high temporal frequencies, and the display image, therefore, contained a large number of spatiotemporal frequencies, within the bandpass of the human visual system, which had the wrong drift direction
Image quality and the display modulation transfer function : experimental findings by Ronald J Evans( Book )

2 editions published in 1993 in English and held by 85 WorldCat member libraries worldwide

Image quality metrics represent an attempt to quantify differences in the quality of the transmission and display of visual information. This report focuses on components in the image transfer process which contribute to image quality as well as tasks through which image quality may be empirically defined. Components consist of the content of the original image, display device characteristics, and observer characteristics. Special attention within these three components is given to the display Modulation Transfer Function (MTF) which has traditionally been the major contributor to image quality metrics. Ambiguities exist in the definition and measurement of display MTFs and these problems are discussed as they pertain to image quality. Additional discussion includes the use of threshold versus suprathreshold tasks as empirical measures of image quality and the use of the Contract Sensitivity Function (CSF) versus the MTF of the eye in image quality metrics. An argument is presented which questions the use of either the CSF or MTF for suprathreshold tasks. In order to test the use of display MTFs in metrics, a methodology is described for digitally filtering images with filter representing hypothetical display MTFS. Although this method permits a subset of display MTFs to be compared, further efforts are required to compare MTFs which exhibit a crossover effect in the spatial frequency domain. Finally, empirical observations suggest that other display parameters (e.g., luminance) must be weighted more heavily in image quality metrics.

Training applications of non-diagnostic intelligent tutoring systems by Leo Gugerty( Book )

1 edition published in 1994 in English and held by 85 WorldCat member libraries worldwide

The keystones of traditional intelligent tutoring systems (ITSs) have been complex procedures for student diagnosis and adaptive instruction based on diagnostic data. While some of these systems have been shown to be effective, they are also very expensive to develop. This paper describes another class of ITSs, non-diagnostic ITSs, which do little or no student diagnosis, and concentrate their intelligence in other areas. Intelligent features of non- diagnostic ITSs include: modeling of expert's reasoning process and cognitive representations (often using graphic displays), comparison of student and expert performance, and replays and summaries of student performance. While traditional, diagnostic ITSs are usually intended to be used in a stand-alone fashion, non-diagnostic tutors are designed to facilitate collaborative learning among students and between teachers and students. The non-diagnostic approach to ITS development offers either a low-cost alternative to traditional ITSs or a way to expand the educational capabilities of traditional systems. This paper presents a framework for comparing the features of non-diagnostic and diagnostic ITSs and data on the costs and educational effectiveness of each type of ITS

Armstrong Laboratory's participation in the Synthetic Theater of War-Europe exercise : a summary report by Robert J Clasen( Book )

2 editions published in 1995 in English and held by 84 WorldCat member libraries worldwide

Armstrong Laboratory's Aircrew Training Research Division (AL/HRA), located in Mesa, AZ, participated in the Synthetic Theater of War-Europe (STOW-E) exercise which occurred on 4-7 Nov 94. The goal of STOW-E was to enhance joint training capabilities by seamless integrating live, virtual, constructive simulations using Distributed Interactive Simulation (DIS) technology. These simulations (which were generated from 17 different sites throughout the United States, England, and Germany) communicated via the Defense Simulation Internet (DSI). AL/HRA provided two high-fidelity F- 16 flight simulator cockpits and associated weapons. In addition, pilots, engineering expertise, and program management expertise were provided. The pilots flew joint simulated air interdiction missions, attacking ground targets. This report summarizes Armstrong Laboratory's participation in STOW-E, focusing on the following topics: the engineering effort that was required for the Laboratory to join STOW-E, how local exercise control and management were obtained, a description of the laboratory's operational scenarios, a listing of lessons learned, and, finally, a chronology of significant STOW-E events
Perceptual dimensions of visual scenes relevant for simulating low-altitude flight by James A Kleiss( Book )

2 editions published in 1992 in English and held by 84 WorldCat member libraries worldwide

Multidimensional scaling was used to identify the features of real- world terrain that are salient to pilots during low-altitude flight. The subjects were pilots experienced flying in the Southwest United States (Experiment 1) and pilots experienced flying in Europe (Experiment 2). The stimuli were videotape segments (Dynamic Presentation) and still photographs (Static Presentation) depicting low-altitude flight over a variety of real-world terrains. Pilots rated pairs of terrains with respect to similarity of visual cues for low-altitude flight. Terrains were also rated on eight bipolar rating scales representing a variety of terrain characteristics thought to be of possible relevance to pilots. similarity ratings were submitted to a multidimensional scaling analysis using the procedure ALSCAL. Two-dimensional solutions were deemed most appropriate in all cases. Bipolar ratings were submitted to a multiple regression analysis in which ratings on each scale were regressed over dimensional coordinates. Results of Experiment 1, Dynamic Presentation, revealed dimensions corresponding to (1) terrain contour, and (2) object size and spacing. Results for Static Presentation were less interpretable suggesting the possibility of a single dimension capturing the presence/absence of global scene detail. In Experiment 2, results for both presentation modes replicated Experiment 1, Dynamic Presentation, although the fit of the data remained superior with Dynamic Presentation. Taken together, these results provide consistent evidence that pilots flying at low altitudes perceive variation in terrain contour and object size and spacing
