Fully Qualified: Are Airmen Truly Trained to Work Independently?

The intent of this research paper is to analyze dynamics directly related to the impact training has on job proficiency, job knowledge, work performance, and organizational success, particularly in the field of military and civilian aerospace and aircraft maintenance. The paper focuses on training policies, practices, and methods employed in the airline industry while also focusing on the policies, practices, and methods associated with the training process utilized within the military aircraft maintenance community. The primary objective in this paper is to uncover methodical, solidified approaches to ensure personnel who maintain or operate within any spectrum of aviation are fully qualified and trained to work productively, avoiding any potential aircraft-related mishaps that could result in loss or damage of equipment, injury to personnel, or death

Concurrent Validity of the Face Valid Food Security Measure

Our objective was to assess the concurrent validity of the face valid food security categorical algorithm with Hawaii residents. We also hypothesized that there would be differences in food security status between ethnic groups. We used the 18 question indicators of the Core Food Security Module (CFSM) to develop the face valid food security measure. The “face valid” measure was created previously by this research team as a more valid food security measure in Hawaii. Findings compared the face valid categorical measure and the CFSM scale measure with various demographic, economic, dietary variables, and use of assistance programs. The sample included 1,603 Hawaii residents drawn from a statewide telephone survey and a survey of charitable food recipients. Statistical analysis included ANOVA, chi-square, and regression analysis of food security measures with related variables. In general, progressively deteriorating food security status resulted in concurrent decreases in vegetable intake, increased reliance on a cheap, high-fat, high-sodium noodle product, and increased reliance on resource augmentation behaviors. Factors such as a greater number of children, limited savings, and recent loss of a job were found to compromise food security status. WIC benefits, frequent use of a food pantry, and the presence of a senior adult in the household appeared protective. In this sample Asians, except for Filipinos, were more food secure; Hawaiians and Part-Hawaiians, and Samoans, were more likely to experience hunger. Findings were consistent with previous work and suggest that the face valid food security measure does exhibit concurrent validity.

Difference in risk perception of onboard security threats by aircrew and aviation security experts

Airlines are increasingly relying on non-security personnel such as cabin crews and pilots to perform a security function when dealing with potential onboard security threats. The training aircrews receive on security threat assessment is considered by many to be inadequate. The way aircrews respond to potential onboard threats can have life and death consequences for passengers and other aircrew. How these potential threats are handled can also cause significant financial loss to the airlines through loss of productivity, passenger claims or even legal liability. For this reason, it is imperative we understand how aircrews perceive security risk in order to make appropriate risk assessments. This study examines if aircrew perceive security risks the same as aviation security experts. Five scenarios representing actual potential onboard security threats were given to a group of 67 pilots, cabin crew and aviation security experts. The participants were asked a series of questions about the scenarios that measured how they perceived the potential threat as well as other questions to determine how prepared they were to deal with each scenario. The results showed that aircrews perceive and assess risk associated with onboard security threats significantly different than aviation security experts

A measurement of the cosmic ray elements C to Fe in the two energy intervals 0.5-2.0 GeV/n and 20-60 GeV/n

The study of the cosmic ray abundances beyond 20 GeV/n provides additional information on the propagation and containment of the cosmic rays in the galaxy. Since the average amount of interstellar material traversed by cosmic rays decreases as its energy increases, the source composition undergoes less distortion in this higher energy region. However, data over a wide energy range is necessary to study propagation parameters. Some measurements of some of the primary cosmic ray abundance ratios at both low (near 2 GeV/n) and high (above 20 GeV/n) energy are given and compared to the predictions of the leaky box mode. In particular, the integrated values (above 23.7 GeV/n) for the more abundant cosmic ray elements in the interval C through Fe and the differential flux for carbon, oxygen, and the Ne, Mg, Si group are presented. Limited statistics prevented the inclusion of the odd Z elements

Prediction of LDEF ionizing radiation environment

The Long Duration Exposure Facility (LDEF) spacecraft flew in a 28.5 deg inclination circular orbit with an altitude in the range from 172 to 258.5 nautical miles. For this orbital altitude and inclination two components contribute most of the penetrating charge particle radiation encountered - the galactic cosmic rays and the geomagnetically trapped Van Allen protons. Where shielding is less than 1.0 g/sq cm geomagnetically trapped electrons make a significant contribution. The 'Vette' models together with the associated magnetic filed models were used to obtain the trapped electron and proton fluences. The mission proton doses were obtained from the fluence using the Burrell proton dose program. For the electron and bremsstrahlung dose we used the Marshall Space Flight Center (MSFC) electron dose program. The predicted doses were in general agreement with those measured with on-board thermoluminescent detector (TLD) dosimeters. The NRL package of programs, Cosmic Ray Effects on MicroElectronics (CREME), was used to calculate the linear energy transfer (LET) spectrum due to galactic cosmic rays (GCR) and trapped protons for comparison with LDEF measurements

Ullrich Krause's Critical Emancipation from Oppressive Reality

In this Master's thesis, I explore the relationship between German philosopher Herbert Marcuse's critical theory and German author Uwe Timm's aesthetic rendering of an individual's critical experience. I focus specifically on Timm's novel Heißer Sommer and its realist depiction of the 68er Bewegung (the West German, leftist student movement). I examine the works of Marcuse that discuss societal domination and its totalizing effects on the human consciousness-- One-Dimensional Man (1964), Repressive Tolerance (1965), An Essay on Liberation (1969), and The Aesthetic Dimension: Toward a Critique of Marxist Aesthetics (1977). The German 68er Bewegung (the student protest movement) was dialectically analyzed by each figure, albeit through different mediums. First, I examine previous criticism on Timm, which overwhelmingly attempts to disenfranchise Timm by accusing him of inundating Heißer Sommer with his subjective and ideological bent. I then discuss how Timm is intimately tied to social criticism, and by association, critical philosophy. For my purposes, Marcuse functions to provide the legitimizing theory that informs Timm's oft-maligned project of political realism: protagonist Ullrich Krause's progression into a liberated member of society hinges on the exposure of "one-dimensionality", societal "insulation", and the annihilation of the private sphere. I argue that Timm succeeds in aesthetically illuminating the progression of the (social) individual into a Marcusean critical stance: fully aware of societal domination and the totalitarian nature of capitalism

Measurements and calculations of the Coulomb cross section for the production of direct electron pairs by energetic heavy nuclei in nuclear track emulsion

Measurements and theoretical predictions of the Coulomb cross section for the production of direct electron pairs by heavy ions in emulsion have been performed. Nuclear track emulsions were exposed to the 1.8 GeV/amu Fe-56 beam at the Lawrence Berkeley Laboratory bevalac and to the 60 and 200 GeV/amu O-16 and the 200 GeV/amu S-32 beam at the European Center for Nuclear Research Super Proton Synchrotron modified to accelerate heavy ions. The calculations combine the Weizsacker-Williams virtual quanta method applicable to the low-energy transfers and the Kelner-Kotov relativistic treatment for the high-energy transfers. Comparison of the measured total electron pair yield, the energy transfer distribution, and the emission angle distribution with theoretical predictions revealed a discrepancy in the frequency of occurrence of the low-energy pairs (less than or = 10 MeV). The microscope scanning criteria used to identify the direct electron pairs is described and efforts to improve the calculation of the cross section for pair production are also discussed
