Power analysis for a proposed group randomized control trial (GRCT) on the Road to Mental Readiness (R2MP) program by Aihua Liu( )

1 edition published in 2014 in English and held by 70 WorldCat member libraries worldwide

The Road to Mental Readiness (R2MR) program is the largest mental health training initiative in the Canadian Armed Forces (CAF). As part of an effort to test the efficacy of R2MR at Basic Military Qualification (BMQ) with a group randomized control trial (GRCT), a robust power analysis was conducted to determine the sample size that would be required for the GRCT on R2MR. Intraclass correlation coefficients (ICCs) were also calculated for the outcomes that will be measured in the GRCT, a necessary preliminary step for the power analysis. Data from the calculation of the ICCs were extracted from multiple programs of ongoing research with the Non- Commissioned Member (NCM) recruits, the intended target population for the GRCT. The results of the analyses suggest that data collected over the course of one full fiscal year will yield sufficient statistical power to detect expected effect sizes for most but not all of the outcomes. It is therefore recommended that data be collected lasting up to one and a half years for the proposed GRCT on R2MR

2 editions published in 2013 in English and held by 51 WorldCat member libraries worldwide

This report outlines the Department of National Defence's approach to moral and ethical decision making outlined in the Defence Ethics Program (DEP), and considers the scientific and military research pertaining to moral and ethical decision making. This work discusses the various conceptual definitions of morality and ethics, and explores the Defense Ethics Program in detail. The DEP argues that several factors influence oral and ethical decision making, which are reviewed. Following this, both formal and informal CF training mechanisms that address moral and ethical decision making are explored. The second part of this review considers the academic and military literature relevant to moral and ethical decision making

Heuristic classification in a simulated air threat task by David J Bryant( Book )

2 editions published in 2005 in English and held by 5 WorldCat member libraries worldwide

Fast and frugal heuristics have proved effective models of human judgment for certain kinds of problems. To further explore the value of this approach, two experiments investigated the decision procedures used by human subjects to perform a cue-based classification task in a simulated aire threat assessment task. Threat assessment is the classification of aircraft on the basis of sensor data that can be likened to probabilistic cues. Subjects learned to classify simulated aircraft using four probabilistic cues, then classified test sets designed to contrast predictions of several heuristics, including the the Take-the-Best-for-Classification (TTB-C) and Pros Rule developed specifically for the threat classification task
Trust vs. confidence by Barbara D Adams( Book )

2 editions published in 2005 in English and held by 5 WorldCat member libraries worldwide

This short theoretical paper works to distinguish the concept of trust from the concept of confidence. Although these terms are often used interchangeably and have some commonalities, this paper argues that they are different in several ways. A confidence judgement typically has a very specific referent, and is influenced by base rates and prior probabilities. A trust judgement has a broader scope and is characterized by a specific lack of information, and by the need to take a "leap of faith" from what is known to what is unknown. Moreover, unlike confidence judgements (which can occur in many situations), trust is only an issue in the presence of risk, uncertainty, vulnerability and the need for interdependency with another person. Without these situational antecedents, trust is not likely to come into play. In short, it is important to make a distinction between the concepts of trust and confidence

The noise simulation facility at DRDC Toronto : room acoustics and system analysis by Ann M Nakashima( Book )

2 editions published in 2005 in English and held by 5 WorldCat member libraries worldwide

The Noise Simulation Facility and the Noise Library at DRDC Toronto are used to recreate the noise environments of various military operational settings. The Noise Simulation Facility (the Noise Lab) is a large room containing an array of speakers that enables the production of noise levels as high as 130 dB. The Noise Library is a collection of digital audio tapes containing recordings of noise that were made in various Canadian Forces land vehicles, aircraft and other operational settings. The acoustical characteristics of the Noise Lab and the quality of the digital audio tape recordings that have been modified for playback are largely unknown. To gain a better understanding of the accuracy to which the operational noise environments are modeled in the Noise Lab, the acoustical response at several different positions in the Noise Lab was measured, and spectral analyses of the noise recordings were performed
The thermal resistance of a winter tent by R. J Osczevski( Book )

2 editions published in 2004 in English and held by 5 WorldCat member libraries worldwide

The primary shelters used by Canadian infantry units in winter are the 5 and 10-man arctic tents. The thermal insulation of a 5-man tent was measured in an environmental chamber, by a new method, using a thermal manikin. A variable amount of heat was added to the interior of the tent with electrical heaters to increase the sensitivity of the method. The contribution of the liner to the total insulation was then easily detected. The method will be useful in comparing tents for cold weather and for assessing the effects of design changes
Latent semantic analysis (LSA) tools by Natalia Derbentseva( )

1 edition published in 2012 in English and held by 4 WorldCat member libraries worldwide

"Latent Semantic Analysis (LSA; Landauer & Dumais, 1997; Landauer, Foltz, & Laham, 1998) is a computational model that uses a large collection of unstructured documents to construct semantic representations for words. The representations are based on a statistical analysis of the terms' occurrences within and across documents, and take the form of a vector"--Introduction, p. 1
The Development of a reliable and valid measure of stressors in policing : a summary of findings from WSIB Development Grant #02-051 by Donald R McCreary( Book )

2 editions published in 2004 in English and held by 4 WorldCat member libraries worldwide

This report describes a project to develop & validate the Operational Police Stress Questionnaire (PSQ-Op) and the Organizational Police Stress Questionnaire (PSQ-Org), two measures tailored to study police stress in the Canadian context. This process was completed over a series of four studies. In the first study, focus groups were used to elicit the stressors associated with policing. In this study, it became apparent that officers separated their stressors into two general categories: operational & organizational. In the other three studies, the PSQ-Op and PSQ-Org were assessed for reliability, validity, & readability. The findings are presented and implications of the research are discussed with regard to the measurement of occupational stress in police officers and the use of the questionnaire data by policy makers to design a less stressful work environment. Copies of the questionnaires are appended
Ionizing radiation detection meter systems usability evaluation by Yvonne D Severs( Book )

2 editions published in 2002 in English and held by 3 WorldCat member libraries worldwide

This report describes & presents results of an evaluation of various candidate ionizing radiation detection meter systems to replace the Canadian Forces ionizing radiation detection meter currently in-service, which is technologically out of date. The system ultimately selected will be used to conduct operations in areas that may be contaminated by low- or tactical-level radiation. The evaluation was conducted in two phases, an operational phase and a training system phase, which rotated three groups of four participants each concurrently through each system tested. Participants rated the utility & usability of each system by measuring ease of use & maintenance under a range of relevant operational & clothing conditions, compatibility with soldier tasks & with clothing, compatibility with equipment & operational environments, and ease of learning. Results are presented for the three systems evaluated and improvements to each each system are suggested
Analysis and interpretation of polygraphic sleep recordings and overnight sleep and fatigue indices during a three-night simulation of noise conditions aboard the International Space Station by Valérie Gil( Book )

2 editions published in 2003 in English and held by 2 WorldCat member libraries worldwide

This research examines the impact on sleep parameters of both noise and a cloistered environment. In the study, 25 subjects were grouped into teams of five and cloistered for three days in a diving chamber in order to simulate conditions aboard the International Space Station. Two teams were exposed to continuous noise day & night, two teams were exposed to the same noise during the day only, and the remaining team was not exposed to noise. Participants were equipped for continuous ambulatory recording of electrophysiological parameters and completed a cognitive test battery during the experiment. Results are presented & compared among the test groups
Risk-attitude scale : methodology and sample characteristics by Elke U Weber( Book )

2 editions published in 2003 in English and held by 2 WorldCat member libraries worldwide

Two initial studies have been conducted towards the goal of applying current theory about risk-taking to military contexts and, in particular, to validate an existing domain-specific risk-taking (DOSPERT) scale (Weber, Blais, & Betz, 2002) for use with American & Canadian adult populations. Study subjects completed seven surveys, including the risk-taking & risk perception responses of an expanded & modified version of the DOSPERT scale. For convergent & discriminant validity evaluation, the studies also included five other scales. This report presents the theoretical background to the studies and describes the study methodology and the characteristics of the sampled population
Prediction of times of facial and finger freezing during cold air exposure by Peter Tikuisis( Book )

2 editions published in 2004 in English and held by 2 WorldCat member libraries worldwide

The occurrence of frostbite can impose severe limitations to survivors and rescuers during a search & rescue operation. The Cold Exposure Survival Model was developed as a search & rescue decision aid to predict the likely time of survival for cold-exposed individuals. Predictions of the risk of frostbite and its rate of onset would enhance the Model by providing a more complete assessment of the casualty's survival status and the risk to the rescuers. This report presents a method for calculating the risk & onset times of frostbite of the bare cheeks & fingers, based on a mathematical model for predicting the rate of tissue cooling. Algorithms for these predictions and guidelines for their implementation are detailed, and their inclusion into the Cold Exposure Survival Model is described

Development of an animal model to investigate the 2D and 3D high image resolution ultrasonic technology using synthetic aperture and adaptive beamformers, part I by Zacharias E Suntres( Book )

2 editions published in 2002 in English and held by 2 WorldCat member libraries worldwide

In military operations, where injuries to the abdominal region are very common, diagnosis of such conditions as organ damage & internal bleeding is difficult. There is a great need to develop a field-deployable ultrasound imaging system that can increase the probability of correct diagnosis in order to ensure appropriate treatment. This report describes an initial part of a project to develop an advanced field-portable three-dimensional (3D) diagnostic imaging system based on planar arrays, adaptive & synthetic aperture beamforming, and 3D visualization imaging techniques. For this project, it is proposed to obtain images of normal & injured organs in rabbits using current ultrasound technology for comparison with images from the newly developed technology. Accordingly, in the research presented here, the effect of lipopolysaccharide (LPS, a bacterial cell wall component commonly used to induce the pathological conditions observed in sepsis & trauma) on the lung, liver, & kidneys of rabbits was examined. LPS-induced damage was assessed by examining changes in organ weights, lipid peroxidation, and glutathione levels. The results indicate whether LPS administration to rabbits is a suitable animal model for obtaining images of normal & injured organs
Development of ELVISS workstation : ELVISS airborne HFE prototype workstation software integration and test report by Brian Neal( Book )

The primary objective of the project is to convert the laboratory prototype into a flyable prototype workstation that could control the real equipment and be operated by Search and Rescue (SAR) Technicians under experimental flight test conditions. The work related to the integration of the Workstation software with the various ELVISS subsystems is documented in this report, along with the results of the Ground and Flight Test activities which were carried out to further demonstrate and evaluate the system's potential to support SAR operations
The effects of individual differences in cognitive styles on decision-making accuracy and latency by Ann-Renée Blais( Book )

2 editions published in 2003 in English and held by 2 WorldCat member libraries worldwide

In the first of two studies described in this report, 48 adults completed three measures of cognitive styles, then completed three trials of a medium-fidelity simulation of a naval surveillance and threat assessment task that required participants to evaluate seven pieces of information for potential targets displayed in a radar space. After reviewing the information for each target, participants submitted their threat assessment and were provided feedback about the degree of actual threat for the target. Results demonstrated the differences in processing time across trials and the effect of cognitive style score on the mean time spent processing the targets. In the second study, 80 Canadian Forces personnel completed the three cognitive styles measures and worked in four-person teams on a simulation similar to the previous one. Each team consisted of three subordinates who separately reviewed & integrated five pieces of complex information per target before forwarding their individual threat assessments to a team leader. The team leader then assessed the veracity of the assessments and integrated them into a final threat assessment for each of 42 targets in each of three sessions. The report discusses the results of these two studies in terms of their relevance with past research in the social attitude literature and their implications for future research
Manikin testing on a variety of land and sea survival equipment by Wendell Durnford( Book )

2 editions published between 2003 and 2004 in English and held by 2 WorldCat member libraries worldwide

This report describes the equipment, procedures, and results of tests conducted on a thermal manikin to evaluate the thermal performance of land & sea survival equipment. The manikin consists of a hollow aluminium human-like form equipped with temperature sensors & electric heaters connected to a computer system. When dressed with apparel to be tested and placed in the test environment, the computer controls the heaters to maintain the manikin skin at a set temperature and measures the electrical power required to do so. That power is equivalent to the heat escaped due to temperature differences across the apparel. The power & temperature differences enable calculation of the apparel thermal resistance. Results are presented from tests conducted in dry & wet conditions with the manikin in winter dress or undressed and accompanied by auxiliary components including a life raft, sleeping bags, life jacket, and a survival bed
