An investigation of correlation between pilot scanning behavior and workload using stepwise regression analysis

An electro-optical device called an oculometer which tracks a subject's lookpoint as a time function has been used to collect data in a real-time simulation study of instrument landing system (ILS) approaches. The data describing the scanning behavior of a pilot during the instrument approaches have been analyzed by use of a stepwise regression analysis technique. A statistically significant correlation between pilot workload, as indicated by pilot ratings, and scanning behavior has been established. In addition, it was demonstrated that parameters derived from the scanning behavior data can be combined in a mathematical equation to provide a good representation of pilot workload

Flight deck benefits of integrated data link communication

A fixed-base, piloted simulation study was conducted to determine the operational benefits that result when air traffic control (ATC) instructions are transmitted to the deck of a transport aircraft over a digital data link. The ATC instructions include altitude, airspeed, heading, radio frequency, and route assignment data. The interface between the flight deck and the data link was integrated with other subsystems of the airplane to facilitate data management. Data from the ATC instructions were distributed to the flight guidance and control system, the navigation system, and an automatically tuned communication radio. The co-pilot initiated the automation-assisted data distribution process. Digital communications and automated data distribution were compared with conventional voice radio communication and manual input of data into other subsystems of the simulated aircraft. Less time was required in the combined communication and data management process when data link ATC communication was integrated with the other subsystems. The test subjects, commercial airline pilots, provided favorable evaluations of both the digital communication and data management processes

Darker than the Dungeon: Music, Ambivalence and the Carceral Subject

Music’s sanctioned role in the day-to-day running of the ‘late-modern’ prison is to ensure wellbeing and compliance of prisoners, with most regimes facilitating access to music through the form of radios, cd’s, and cassette players. As a result, music often comes tied to judgements by the regime about prisoners’ conduct, with incentive systems allowing the regime to confiscate earned possessions under certain conditions. In this way, the role of music in prison is often continuous with the mechanisms of carceral control, with its ‘humanising’ or ‘therapeutic’ effects being defined as a luxury to be earned through good behaviour and critical engagement with one’s moral and psychological treatment. By tracing the history of music during the birth of the modern prison in the nineteenth century, this paper asks how music became incorporated into the discourse and technology of the emerging carceral state. Drawing principally on the work of Michel Foucault, this paper seeks to explore the relationship between music and ‘the self’ as it is applied to carceral subjects. Foucault shows how the expansion of the carceral state at the end of the nineteenth century relied on the production of knowledge about the subject through the application of disciplinary techniques. By exploring the construction of the self through the discourse of music at the end of the eighteenth century and in the published works of carceral reformers at the end of the nineteenth century, this paper seeks to explore the role that music played within this period of carceral expansion. The discussion will focus on the ways in which music acts as a conduit for forms of carceral power through its relationship with the self

If only it were true: the problem with the four conditionals

The traditional division of conditionals into four main types (zero, first, second, and third) has long been called into question. Unfortunately, the awareness that this description does not reflect conditional patterns in actual usage has not generally been reflected in EFL coursebooks. This article re-examines the arguments for a description of conditional patterns which reflects actual usage and uses corpus data to demonstrate the kind of patterns in frequent use. It then suggests two teaching approaches that may help teachers to tackle a variety of conditional patterns in the classroom

A piloted simulation study of data link ATC message exchange

Data link Air Traffic Control (ATC) and Air Traffic Service (ATS) message and data exchange offers the potential benefits of increased flight safety and efficiency by reducing communication errors and allowing more information to be transferred between aircraft and ground facilities. Digital communication also presents an opportunity to relieve the overloading of ATC radio frequencies which hampers message exchange during peak traffic hours in many busy terminal areas. A piloted simulation study to develop pilot factor guidelines and assess potential flight crew benefits and liabilities from using data link ATC message exchange was completed. The data link ATC message exchange concept, implemented on an existing navigation computer Control Display Unit (CDU) required maintaining a voice radio telephone link with an appropriate ATC facility. Flight crew comments, scanning behavior, and measurements of time spent in ATC communication activities for data link ATC message exchange were compared to similar measures for simulated conventional voice radio operations. The results show crew preference for the quieter flight deck environment and a perception of lower communication workload

Users guide: The LaRC human-operator-simulator-based pilot model

A Human Operator Simulator (HOS) based pilot model has been developed for use at NASA LaRC for analysis of flight management problems. The model is currently configured to simulate piloted flight of an advanced transport airplane. The generic HOS operator and machine model was originally developed under U.S. Navy sponsorship by Analytics, Inc. and through a contract with LaRC was configured to represent a pilot flying a transport airplane. A version of the HOS program runs in batch mode on LaRC's (60-bit-word) central computer system. This document provides a guide for using the program and describes in some detail the assortment of files used during its operation

A Dietary Analysis on Panamanian Bat Species

Bats are found all over the world, and they are the most diverse group of mammals in the tropics. They are a key component in all ecosystems as predators, pollinators, or seed dispersers. As a conservation tool, dietary studies show what different bat species need to survive. Through metabarcoding, the diet can be accurately assessed. This method involves the DNA extraction of material from the feces of the individual being studied. PCR is used to amplify the DNA and next generation sequencing is used to identify, separate, and align the DNA that was extracted. By comparing the results from different seasons, we are able to track changes in diet based on seasonal variance and eventually anthropogenic sources. Due to unforeseen problems with sampling technique, the results of this study were not significant. A larger data set and improved sterilization is needed to confirm any changes within species and between seasons

The Jesness Inventory as a Predictor of Firesetters from Non-Firesetters Among Children 8-18: A Discriminant Analysis

The Jesness Inventory and several demographic variables were evaluated using linear discriminant analysis to explore the major question: Can the Jesness Inventory scales accurately discriminate and then classify firesetters and non-firesetters? Psychiatric hospital records of children ages 8-18 were reviewed at two hospitals from August 1983 to October 1985. Twenty-five patients who had engaged in firesetting behavior and a comparison group of fifty-one hospitalized non-firesetting children who had taken the Jesness Inventory during their hospitalization were selected for the study. Three linear discriminant analyses were run. The major finding was that the Jesness Inventory was unable to satisfactorily classify firesetters from non-firesetters. This discriminant function classified 52% of the non-firesetters and 70% of the firesetters correctly, for a total of 58% correct. This result is only slightly higher than what would be predicted by chance. A second discriminant analysis, which combined the demographic variables with the Jesness Inventory scales, was able to classify 71% of the non-firesetters and 70% of the firesetters accurately for a total of 71% correct classifications. Firesetters were discriminated from non-firesetters by the variables age, sex, adoption, and the Jesness Inventory scales: Immaturity, Withdrawal, and Autism. Firesetters tended to be younger in age, male, adopted, and scored higher on the Immaturity and Withdrawal scales. The third discriminant function used only the demographics as predictor variables and found that 86% of the non-firesetters and 80% of the firesetters were classified accurately, for a total of 84% correct classifications. Again age, sex, and adoption history entered the equation. These findings tend to cast doubt on the ability of the Jesness Inventory to discriminate and classify children who set fires, and continue to support other studies that have found child self-report instruments unable to discriminate firesetters from comparison groups

Death of a Treaty: The Decline and Fall of the Antarctic Minerals Convention

On June 2, 1988, in Wellington, New Zealand, thirty-three states signed the Convention on the Regulation of Antarctic Mineral Resources. This agreement, the product of six years of negotiation, fills a significant gap in the Antarctic Treaty System: it provides rules governing the prospecting, exploration, and development of minerals in Antarctica. Recently, however, two Antarctic Treaty Consultative Parties--France and Australia--have refused to ratify the Minerals Convention, instead advocating a permanent ban on mineral activities in Antarctica. Their opposition thwarts plans for the ratification of the Minerals Convention. This Note provides an overview of the present Antarctic Treaty System, sets forth the provisions of the Minerals Convention in detail, and discusses the Convention\u27s strengths and weaknesses. Finally, this Note outlines the events that led to the collapse of the Convention
