The Effect Of Video Weather Training Products On General Aviation Pilots’ Flight Behavior, William Knecht, Jerry Ball

International Symposium on Aviation Psychology - 2009

This study examined the effect of video weather training products on general aviation (GA) pilot flight behavior. Fifty pilots participated. Training products were two popular GA weather training videos, plus a non-weather video as control. Pilots watched one video. Then, in the CAMI flight simulator, they flew a challenging 1.5-h visual flight rules (VFR) mission. Along the route, terrain rose slowly, with cloud bases squeezing pilots between ground and clouds. The control group penetrated significantly farther into the deteriorating weather. Otherwise, no significant safety differences were observed for time spent in instrument meteorological conditions (IMC), time scud running, or time …

Solution Space-Based Complexity Analysis Of Atc Aircraft Merging Tasks, Patrick Hermes, Max Mulder, M.M. (René) Van Paassen, Hans Huisman, J.H.L. (Harjan) Boering

International Symposium on Aviation Psychology - 2009

Air traffic controller workload is considered to be a limiting factor in the growth of air traffic. In this paper a new method of assessing controller task demand load will be developed and tested. Based on the hypothesis that workload is primarily caused by the complexity of the task to be conducted, the concept of the “solution space” is described. For any particular air traffic control problem, the solution space describes the constraints in the environment that limit (and therefore, guide) air traffic controller decisions and actions. The complexity of that particular control problem can then be analyzed by considering …

The Effect Of Human Factors In Aviation Maintenance Safety, Andrea M. Georgiou

International Symposium on Aviation Psychology - 2009

Even with the increasing rate of technology innovation, the ultimate responsibility for the safety of a flight lies with humans. According to Boeing, human error accounts for 70% of commercial airplane accidents. This research aims to investigate the human factors that exist in aviation maintenance as well as the extent to which these factors affect safety. Utilizing the National Transportation Safety Board (NTSB) online accident database, the researcher reviewed accidents between 1996 through 2006 caused by maintenancerelated errors. The results indicate the top four maintenance errors with the highest number of fatalities were: a).failure to properly complete tasks, b).improper maintenance, …

Countermeasures To Mitigate Effects Of Fatigue Among Flight Attendants: To Improve Transportation Safety And Productivity, Lori J. Brown, John Niehaus

International Symposium on Aviation Psychology - 2009

As airlines restructure and cut corners to make ends meet, flight attendants are experiencing a new industry trend that must be put to rest. At many carriers, flight attendants are forced to work to the point of exhaustion because of poorly scheduled duty time, lengthened duty days, or flagrant company violations of schedules. Research efforts on human factors: including the effects of fatigue, sleepiness, sleep disorders and circadian rhythms—on transportation safety has become a top priority. Research has identified key findings concerning fatigue in the flight attendant occupation, where sleep deprivation and disruption of circadian rhythms are known to occur …

Situational Awareness Assessment In Flight Simulator Experiment, Henk Van Dijk, Koen Van De Merwe, Rolf Zon

International Symposium on Aviation Psychology - 2009

Within the HILAS (Human Integration into the Lifecycle of Aviation Systems) project a flight simulator experiment was performed. The aim of the experiment was to study and select relevant Human Factors tools for pilot Situational Awareness assessment. One specific scenario was designed in which a malfunction of the aircraft was simulated: an Indicated Air Speed discrepancy. The malfunction was introduced during flight and slowly progressed over time while researchers monitored if and how pilots detected the discrepancy. Pilot behaviour was studied during the scenario; i.e. pilots’ Situational Awareness was assessed via eye trackers and rating scales.

Implementation Issues For Uav Camera View Transition Display Aid, Nicholas Wright, Heath Ruff, Brian Mullins, Antonio Ayala, Gloria Calhoun, Mark Draper

International Symposium on Aviation Psychology - 2009

An operator supervising multiple unmanned aerial vehicles (UAVs) will be required to switch attention between UAVs, each potentially involving different scenario environments and task requirements. A transition aid is now under evaluation that employs synthetic vision technology to enhance an operator’s situation awareness when switching between UAVs. Instead of discretely switching from the camera view of one UAV to the camera view of another, the algorithms driving the transition automatically provide a display format that uses a “fly out, fly in” metaphor over several seconds to transition between the two camera views. This paper will describe the many parameters that …

Training Interventions To Reduce Air Force Predator Mishaps, Robert Nullmeyer, Gregg Montijo

International Symposium on Aviation Psychology - 2009

The use of unmanned aerial systems (UASs) is expanding rapidly. In military operations, this increased use has been accompanied by relatively high mishap rates compared with rates across more mature manned aircraft. These higher rates led to multiple high-level reviews of unmanned operations, but surprisingly little consensus emerged across reports regarding root causes. To help close this gap, Air Force Predator Class A mishap reports through FY 2008 were analyzed in detail. Mishap rates, counts, and causal factors appeared to shift systematically over time, with an increase in mishap reports citing shortfalls in several skill and knowledge areas in FY …

Contribution Of High-Frequency Eeg Features To Physiogicallybased Operator Workload Estimation, Jason W. Monnin, Justin R. Estepp

International Symposium on Aviation Psychology - 2009

Physiologically-based cognitive workload assessment can discriminate changing levels of operator functional state in complex task environments. In this paradigm, electroencephalography (EEG) is a commonly used physiological measure. Spectral power in clinical frequency bands is used to derive features to train an artificial neural network (ANN) classifier to recognize changes in cognitive workload. Recent research has suggested that power in high frequency bands may be influenced by electromyographic artifact. In a previous study, nineteen channels of EEG were recorded (from 10 participants) during a complex uninhabited air vehicle (UAV) control simulation in which task difficulty was manipulated to induce changes in …

The 787 Vertical Situation Display Human Factors Evaluation Enhancements To Flight Path Awareness, Jason Hammack, Julianne Fox Cummings, Jean Crane

International Symposium on Aviation Psychology - 2009

A two-phased focused evaluation was run to validate the design implementation of the 787 Vertical Situation Display (VSD), using static and dynamic scenarios in a prototype flight deck. Pilot feedback and pilot questionnaire data were recorded and videotaped for analysis. The validation testing results suggest that overall an effective implementation has been designed. There was one area where issues were found that necessitated requirement changes. The mode transition logic (during takeoff) was redesigned and additional validation testing was conducted to ensure acceptability.

Automation Dependency Under Time Pressure, Stephen Rice, David Keller, Gayle Hunt, David Trafimow

International Symposium on Aviation Psychology - 2009

Previous research has identified many factors that affect human dependence on automated systems. Some of these factors include automation reliability, types of errors, and training. This study introduces a new factor, time pressure, which is directly related to operator dependence on automated aids. Participants were asked to perform a simulated UAV target-detection task with the aid of diagnostic automation. Two factors were manipulated in this study: reliability of the automation and time pressure. The results indicate that participants faced with time pressure were more likely to depend on the automation than participants who had more time to evaluate the recommendations. …

An Investigation Of The Behavioral Mechanisms Of Antipsychotic Action Using A Drug-Drug Conditioning Paradigm, Ming Li, Wei He, Alexa Mead

Department of Psychology: Faculty Publications

Antipsychotic drugs at noncataleptic doses selectively suppress conditioned avoidance response in rats. In our previous study, we had used a two-way active avoidance response paradigm to show that the antipsychotic-induced interoceptive state is one of the mechanisms underlying the avoidance-disruptive effect of antipsychotics. In this study, we sought to further examine this mechanism using a novel drug-drug conditioning procedure. We made use of the fact that both the typical neuroleptic haloperidol and the atypical neuroleptic olanzapine disrupt conditioned avoidance responding, whereas chlordiazepoxide (an anxiolytic) does not. We reasoned that if the antipsychotic interoceptive state is important in causing a disruption …

Measurement And Mitigation Of Laboratory Animal Distress Sources Of Distress In The Animal Laboratory, Larry Carbone

Laboratory Experiments Collection

Pain and distress differ, but overlap. For the purposes of this discussion, we will consider pain to involve nociceptive input of stimuli that are potentially tissue damaging, and that further include an unpleasant emotional component (Merskey and Bogduk 1994). Pain need not necessarily induce distress, as when an animal or human willingly undergoes some painful situation in order to achieve a desired reward. In that case, while the pain may be unpleasant, it is not so severe as to be intolerable. Likewise, there are many potential causes of distress that do not involve physical pain.

Resolving Animal Distress And Pain: Principles And Examples Of Good Practice In Various Fields Of Research, Alicia Karas, Matthew C. Leach, Karl A. Andrutis, Kathleen Conlee, John P. Gluck, Andrew N. Rowan, Martin L. Stephens

Laboratory Experiments Collection

Pain and distress are central topics in legislation, regulations, and standards regarding the use of animals in research. However, in practice, pain has received greatly increased attention in recent years, while attention to distress has lagged far behind, especially for distress that is not induced by pain. A contributing factor is that there is less information readily available on distress, including practical information on its recognition, assessment and alleviation.

This chapter attempts to help fill that void by reversing the usual pattern and giving greater attention to distress than to pain. In addition, we also bypass the pain versus distress …

Personal Reflections On Russell And Burch, Frame, And The Hsus, Martin Stephens

Animal Welfare Collection

The coincidence of anniversaries associated with the publication of William Russell and Rex Burch’s The Principles of Humane Experimental Technique, the founding of the Fund for the Replacement of Animals in Medical Experiments (FRAME), and the establishment of the collaboration between FRAME and the University of Nottingham, provides an opportunity to reflect on Russell and Burch’s legacy and how it was carried forward by FRAME. The Principles, published in 1959, was the pioneering work in what later became the alternatives or Three Rs field of replacement, reduction, and refinement of animal use. Such was the book’s initial and undeserved obscurity, …

Reflective Materials And The Use Of Glitter In Art Therapy, Amber Dee Mazza

Art Therapy | Master's Theses in Print

This paper hypothesizes that glitter is an important media in art therapy. This research asked the question, what is the significance and clinical application of glitter in art therapy? Glitter is a commonly used art material and research on the subject matter is absent. The method used was survey research with quantitative and qualitative questions. Seven hundred and fifty eight members of the American Art Therapy Association completed the survey. Glitter has significant meaning in reference to Cathy Moon’s theory of materiality, and can be used to bring light to client art work.

Group Feeding For The Lactating Cow, Anthony Joseph Martin

Dairy Science

Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …

Exposure To Pesticides And Breast Cancer Revisited, Samantha Shapiro

International Journal of Global Health and Health Disparities

Pesticide use raises a number of environmental health concerns for the general public as pesticides are commonly used to increase agricultural productivity and control invading insects, weeds, fungi and rodents (Jurewicz et al., 2006). Pesticides have been suspected to present danger to consumers and bystanders, as well as workers during the manufacturing and transporting process of these chemicals. This is a problem of great significance because if pesticides do play a role in the etiologies of breast cancer, many people are put at an increased risk in their daily lives by consuming and inhaling such toxins. Due to the fact …

Breast Feeding And Obesity Prevention In Children, Erin J. Kennedy

International Journal of Global Health and Health Disparities

The focus of this paper is to provide a review of current research regarding the possible protective effect of breast feeding against childhood obesity. This relationship is of importance as the United States is not immune to the obesity epidemic in children (Institute of Medicine, 2008). Over the past 30 years, the childhood obesity rate defined as at or greater than the 95th percentile for age has tripled in children aged 2-5 years old and adolescents aged 12-19 years old, and doubled in children aged 6-11 years old. In 2000, the prevalence of obesity was 10% for age 2-5 year …

Childhood Vaccination And Autism, Peggy K. Brinkman

International Journal of Global Health and Health Disparities

In March, 2008, parents of a girl in Georgia were ruled to be entitled to compensation because their daughter developed autistic symptoms after being vaccinated with childhood vaccines (Doheny, 2008). This ruling truly questions the necessity of vaccination for childhood diseases and puts the question in the mind of every parent as to if they should vaccinate their child or not. The purpose of this study is to review literature on the epidemiologic relationship between childhood vaccinations and the development of autism.

The Influence Of Affect, Attitude And Usefulness In The Acceptance Of Telemedicine Systems, Soussan Djamasbi,, Ann L. Fruhling, Eleanor T. Loiacono

Information Systems and Quantitative Analysis Faculty Publications

Grounded in current theories of affect this study examines the role positive and negative moods play on the acceptance of a specialized telemedicine system for microbiology consultation and diagnostics, referred to as telepathology. From a laboratory experiment using microbiology laboratory assistants, the notion that healthcare users’ attitude is an important factor in the acceptance behavior of a healthcare information system is supported. A regression analysis of the data revealed the need to tailor the IS Technology Acceptance Model for the healthcare field. Specifically, our results show that ease of use which is thought to be a main antecedent of end-user …

Novel Word Learning Of Children With Hearing Impairment And Children With Typical Hearing, Matthew R. Clark

Theses, Dissertations and Capstones

Children with hearing impairment may be at risk for reading difficulty due, in part, to delayed vocabulary development. However, advances in amplification technology, most notably cochlear implant technology, make it possible for children with profound hearing loss to acquire oral language. This study asked if novel word learning differed between children with typical hearing and those with severe to profound hearing loss who either wore hearing aids or had cochlear implants. Children learned nonsense words as names for Beanie Babies during a play scenario and were later asked to identify and name each Beanie Baby using its correct nonsense word …

Endothelial Cells And Pulmonary Arterial Hypertension: Apoptosis, Proliferation, Interaction And Transdifferentiation, Seiichiro Sakao, Koichiro Tatsumi, Norbert F. Voelkel

VCU Health Publications

Severe pulmonary arterial hypertension, whether idiopathic or secondary, is characterized by structural alterations of microscopically small pulmonary arterioles. The vascular lesions in this group of pulmonary hypertensive diseases show actively proliferating endothelial cells without evidence of apoptosis. In this article, we review pathogenetic concepts of severe pulmonary arterial hypertension and explain the term "complex vascular lesion ", commonly named "plexiform lesion", with endothelial cell dysfunction, i.e., apoptosis, proliferation, interaction with smooth muscle cells and transdifferentiation.

Risk Factors For Human Infection With Puumala Virus, Southwestern Germany, Anne Caroline Schwarz, Ulrich Ranft, Isolde Piechotowski, James E. Childs, Stefan O. Brockmann

Zoonotics and Wildlife Disease: Publications

Puumala virus, which causes nephropathia epidemica (NE), is the most prevalent hantavirus in Germany; bank voles serve as the main reservoir. During 2001–2007, most NE cases reported from Germany occurred in the southwestern state of Baden-Württemberg. We investigated the influence of bank vole habitats (beech forest, seed plants), vole food supply (beechnut mast), climate factors (winter and spring temperatures), and human population density on spatial and temporal occurrence of NE cases in Baden- Württemberg. Using Poisson-regression analyses, we found that all these factors influenced disease incidence. Furthermore, an independent trend of increasing incidence predicted that incidence will nearly double each …
