A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, 2017 DLR-German Aerospace Centre
A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, Daniela Schmid
Mental workload of a pilot, in short workload, depends on various characteristics of different accumulated tasks on the flight deck. Exogenous task demands and endogenous supply of attentional or information processing resources determine workload . Performance is expect to drop if the demand exceeds the available resources of the pilot. Expertise and experience modulate the endogenous sup- ply of resources like perceiving, updating memory, planing, making a decision, and executing and processing a response. Subsequently, workload manifests in performance variables, subjective experience, and physiological parameters . This is how we can summarize workload very brie y to introduce a model ...
A Systems Approach To Predicting And Measuring Workload In Rail Traffic Management Systems, 2017 Thales GTS, Human Factor Engineer
A Systems Approach To Predicting And Measuring Workload In Rail Traffic Management Systems, Joanna Evans
The introduction of systems such as Traffic Management (TM) will result in a number of changes in how the railway is managed for operations and maintenance staff such as, an increase in collaborative working styles and shared responsibilities. In order to react to these changing operational demands and user needs, TM workstation designs need to have greater flexibility and be configurable to support the information requirements for each specific role as well as support each role during different scenarios. Although this flexibility in system design has the potential to enhance performance, it increases the complexity of measuring operator workload. The ...

Psychophysiological Measures Of Mental Effort And Emotion Within User Research, 2017 Iowa State University
Psychophysiological Measures Of Mental Effort And Emotion Within User Research, Chase Rubin Meusel
Graduate Theses and Dissertations
Psychophysiological measures have potential to aid the discipline of user research, but are currently under-utilized. Currently, across both academia and industry there is a need to increase the quality and quantity of feedback garnered from individuals during user tasks. Psychophysiological measures are beneficial in that they can collect data objectively, unobtrusively, and in real-time. The work put forth in this dissertation focuses on two separate contexts in which psychophysiological measures are used to increase the overall quality of user research data. The first context is described in Chapters 2 and 3, in which electrodermal activity (EDA) within a high fidelity ...

Doctoring Undercover: Updating The Educational Tradition Of Shadowing, 2016 University of Kentucky
Doctoring Undercover: Updating The Educational Tradition Of Shadowing, Claire D. Clark
Behavioral Science Faculty Publications
Background: Premedical students are educated in basic biological and health sciences. As a complement to traditional premedical coursework, medical school applicants are encouraged to shadow practitioners, with the hope that observation will introduce students to the culture and practice of healthcare. Yet the shadowing experience varies widely across practitioners and institutions; resources that guide students’ critical reflection and structure the experience are scarce.
Development: A pilot experiential learning course, Doctoring Undercover: Shadowing and the Culture of Medicine, was developed to fill this gap. The course consisted of three parts: an introduction to medical culture through the disciplines of medical sociology ...
Implementation Of A Computerized Screening Inventory: Improved Usability Through Iterative Testing And Modification, 2016 University of Massachusetts Medical School
Implementation Of A Computerized Screening Inventory: Improved Usability Through Iterative Testing And Modification, Edwin D. Boudreaux, Andrew Christopher Fischer, Brianna Haskins, Zubair Saeed Zafar, Guanling Chen, Sneha A. Chinai
Edwin D. Boudreaux
BACKGROUND: The administration of health screeners in a hospital setting has traditionally required (1) clinicians to ask questions and log answers, which can be time consuming and susceptible to error, or (2) patients to complete paper-and-pencil surveys, which require third-party entry of information into the electronic health record and can be vulnerable to error and misinterpretation. A highly promising method that avoids these limitations and bypasses third-party interpretation is direct entry via a computerized inventory.
OBJECTIVE: To (1) computerize medical and behavioral health screening for use in general medical settings, (2) optimize patient acceptability and feasibility through iterative usability testing ...

Keeping Weight Off: Study Protocol Of An Rct To Investigate Brain Changes Associated With Mindfulness-Based Stress Reduction, Carl E. Fulwiler, Julia A. Siegel, Jeroan J. Allison, Milagros C. Rosal, Judson A. Brewer, Jean A. King
Open Access Articles
INTRODUCTION: Obesity is a growing epidemic fuelled by unhealthy behaviours and associated with significant comorbidities and financial costs. While behavioural interventions produce clinically meaningful weight loss, weight loss maintenance is challenging. This may partially be due to failure to target stress and emotional reactivity. Mindfulness-based stress reduction (MBSR) reduces stress and emotional reactivity and may be a useful tool for behaviour change maintenance. This study seeks to provide a mechanistic understanding for clinical trials of the benefits of MBSR for weight loss maintenance by examining changes in functional connectivity (FC) and the association of these changes with clinical outcomes.

Open Access Articles
BACKGROUND: Indoor tanning elevates the risk for melanoma, which is now the most common cancer in US women aged 25-29. Public policies restricting access to indoor tanning by minors to reduce melanoma morbidity and mortality in teens are emerging. In the United States, the most common policy restricting indoor tanning in minors involves parents providing either written or in person consent for the minor to purchase a tanning visit. The effectiveness of this policy relies on parents being properly educated about the harms of indoor tanning to their children.
OBJECTIVE: This randomized controlled trial will test the efficacy of a ...

Oxytocin’S Effects On Sickness Behaviours, Anxiety Responses, And Immune Function In Adult Male Mice, 2016 The University of Western Ontario
Oxytocin’S Effects On Sickness Behaviours, Anxiety Responses, And Immune Function In Adult Male Mice, Julie Deleemans
Electronic Thesis and Dissertation Repository
The nonapeptide, oxytocin (OT), is implicated in a range of behavioural and physiological functions. However, OT's role in sickness behaviours remains unclear. This thesis examined effects of the OT agonist, carbetocin (CBT), and OT antagonist, L-368,899, on anxiety and locomotor sickness-related behaviours and pro-inflammatory cytokines, TNF-a and IL-6, in adult male CD-1 mice. Animals received 2 intraperitoneal treatment injections. The first treatment was carbetocin, L-368,899, or saline, while the second was lipopolysaccharide (LPS) or saline. Behaviours were evaluated via the light-dark test, and cytokines via immunoassay. OT antagonist treatment attenuated LPS induced perturbations in locomotor and ...

Department of Pediatrics Faculty Papers
INTRODUCTION: The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant.
METHOD: Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smokingsociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression.
RESULTS: Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it ...

Simple Messages To Improve Dietary Quality: A Pilot Investigation, Barbara C. Olendzki, Yunsheng Ma, Kristin L. Schneider, Philip A. Merriam, Annie L. Culver, Ira S. Ockene, Sherry L. Pagoto
Ira S. Ockene
Public health recommendations for a healthy diet often involve complex messages, requiring in-depth knowledge for understanding and compliance. The present study compared the feasibility and initial efficacy of two simple messages (a high fiber diet or a low saturated fat diet) to a combination message (high fiber and low saturated fat) on the potential to impact dietary quality and metabolic health. Conclusions: A simple dietary message appears to improve overall dietary quality and aid in weight management. Simple messages are a novel approach which could make a significant impact on the prevention and treatment of chronic disease as well as ...
