A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, Daniela Schmid

H-Workload 2017: Models and Applications (Works in Progress)

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 [1]. 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 [2]. This is how we can summarize workload very brie y to introduce a model …

Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown

H-Workload 2017: Models and Applications (Works in Progress)

Automated driving has been predicted to take-over from manual vehicle control in the near future. The driver’s role may then change from active operator to passive observer. Such technology offers the tantalising promise of improving driving safety. However, many studies have presented findings suggesting potentially adverse effects from automated driving systems, e.g., reduced situation awareness. Mental workload is also a key issue of concern for researchers in this area. Excessive mental workload has repeatedly been shown to be associated with degraded driving performance. Previously, most traffic psychology studies on mental workload have focused the manual driving task. However, a shift …

Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst

H-Workload 2017: Models and Applications (Works in Progress)

In efforts to increase safety and reduce peak workload situations in the cockpit, a tool with a different interaction style was developed for use in case of a runway change instructed by Air Traffic Control during approach. In an experiment a workload comparison was made between the new tool and the conventional cockpit. Workload was measured by means of a self-rating after each experiment run, as well as eye blink frequency during each run. Results show that the self-rated workload decreases with the new tool for one of the two crew members and the blink frequency suggests a workload decrease …

Facing Human Workload: The Resilient Ego: A Psychoanalytic Point Of View, Glauco Maria Genga, Maria Gabriella Pediconii

H-Workload 2017: Models and Applications (Works in Progress)

The paper aims to show new connections among Human Factors, Human Workload and Resilience. We intend: 1) to highlight the role of subject in facing the human workload, inflected as demanding tasks and emergency situations; 2) to show how psychoanalysis can provide novel insights, not only into human errors, but also into human resilience. They have a common denominator, at least in part: the role of subjective contributions even in demanding situations. Human workload includes a work for satisfaction. We recall also the case study of US Airways Flight 1549 water landing (the so called “Miracle on the Hudson”), which …

System Identification Of Motion Artifact: Noise In Eeg Headsets From Locomotion, Kaela Shea, James Tung

H-Workload 2017: Models and Applications (Works in Progress)

Fall prevention for geriatric populations is a growing concern among clinicians and researchers due to severe risk of morbidity and loss of independence. Emerging evidence has demonstrated that mental workload while walking influences gait stability and the risk for falling. Electroencephalography (EEG) presents a potential method to provide objective measures of mental workload, particularly during daily activities. Noise introduced to the EEG signal during motion, however, is restrictive. The study presented in the following paper isolates EEG signal noise attained from gait for a commercially accessible EEG system, the "Emotiv" Time and spectral system identification techniques were applied to model …

Online Measuring Of Available Resources, Enrique Munoz-De-Escalona, José Juan Canas

H-Workload 2017: Models and Applications (Works in Progress)

This paper present a proposal for measuring available mental resources during the accomplishment of a task. Our proposal consists in measuring emotions provoked by perceived self-efficacy in the execution of the task. Self-efficacy is one of the most important factors that affect the resources that a person puts at the disposal of the execution of the task. When a person perceives that he/she is not being effective he/she will activate more resources to improve his performance. This self-efficacy will be reflected in the emotions that the person experiences. A good efficacy will provoke positive emotions and a bad efficacy negative …

A Meta-Analysis Of The Prevalence Of Different Functions Of Non-Suicidal Self-Injury, Peter Taylor, Khowla Jomar, Katie Dhingra, Rebecca Forrester, Ujala Shahmalak, Joanne M. Dickson

Research outputs 2014 to 2021

Background

A broad variety of different functions can underlie acts of Non-suicidal self-injury (NSSI). Whilst research so far has identified many of the commonly reported functions, no reliable estimates of prevalence currently exist for these different NSSI functions. Understanding the prevalence of NSSI functions represents a key to better understanding the phenomenology of NSSI and addressing the differing needs of the NSSI population. We conducted a systematic review and meta-analysis of the prevalence of NSSI functions in community and clinical samples.

Method

A literature search of electronic databases PsycINFO, Medline, and Web of Science from date of inception to March …

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, …

University Students' Involvement In A Health Promoting Lifestyle: Influencing Factors Of The Health Promotion Model, Madison Estrada

Electronic Theses & Dissertations

Abstract: This is a correlational study utilizing Nola Pender’s Health Promotion Model (HPM) for examining the key influential factors regarding involvement in a health promoting lifestyle (HPL) among undergraduate students at Pittsburg State University. Ninety-six (96) undergraduate students enrolled in general psychology courses at Pittsburg State University completed the Health Promoting Lifestyle Profile-II (HPLP-II; Walker, Sechrist, & Pender, 1987), the Exercise Benefits/Barriers Scale (EBBS; Pender, Walker, & Sechrist, 1987), the Self-Efficacy for Exercise Scale (SEE Scale; Resnick & Jenkins, 2000), and the Physical Activity Stages of Change Questionnaire (Marcus, Selby, Niaura, & Rossi, 1992). Spearman Correlation coefficients (one-tailed tests), were …

Stimulus Threat And Exposure Context Modulate The Effect Of Mere Exposure On Approach Behaviors, Steven G. Young, Isaiah F. Jones, Heather M. Claypool

Publications and Research

Mere-exposure (ME) research has found that initially neutral objects made familiar are preferred relative to novel objects. Recent work extends these preference judgments into the behavioral domain by illustrating that mere exposure prompts approachoriented behavior toward familiar stimuli. However, no investigations have examined the effect of mere exposure on approach-oriented behavior toward threatening stimuli. The current work examines this issue and also explores how exposure context interacts with stimulus threat to influence behavioral tendencies. In two experiments participants were presented with both mere-exposed and novel stimuli and approach speed was assessed. In the first experiment, when stimulus threat was presented …

Journal of Patient-Centered Research and Reviews

Background: Since 2003, electronic cigarettes (e-cigs) have grown in popularity. E-cigs are often marketed as a safer, healthier alternative to smoking traditional cigarettes or as an aid for smoking cessation. However, the risks and benefits of e-cig use, as well as the beliefs that influence use or avoidance, are poorly understood.

Purpose: To assess our patient population’s perception or beliefs as they relate to e-cig use.

Methods: A 13-question survey regarding nicotine and e-cig use was distributed to English-speaking adult patients at Aurora St. Luke’s Family Practice Clinic from August 2015 to January 2016. Questions assessed patient demographics and smoking …

Chronic Binge Alcohol Administration Dysregulates Hippocampal Genes Involved In Immunity And Neurogenesis In Simian Immunodeficiency Virus-Infected Macaques, John K Maxi, Matt Dean, Jovanny Zabaleta, Krzysztof Reiss, Gregory J. Bagby, Steve Nelson, Peter J. Winsauer, Francesca Peruzzi, Patricia E. Molina

School of Graduate Studies Faculty Publications

Alcohol use disorders (AUD) exacerbate neurocognitive dysfunction in Human Immunodeficiency Virus (HIV+) patients. We have shown that chronic binge alcohol (CBA) administration (13-14 g EtOH/kg/wk) prior to and during simian immunodeficiency virus (SIV) infection in rhesus macaques unmasks learning deficits in operant learning and memory tasks. The underlying mechanisms of neurocognitive alterations due to alcohol and SIV are not known. This exploratory study examined the CBA-induced differential expression of hippocampal genes in SIV-infected (CBA/SIV+; = 2) macaques in contrast to those of sucrose administered, SIV-infected (SUC/SIV+; = 2) macaques. Transcriptomes of hippocampal samples dissected from brains obtained at necropsy (16 …

Circumcision Status Is Not Associated With Condom Use And Prevalence Of Sexually Transmitted Infections Among Young Black Msm, Richard A. Crosby, Cynthia A. Graham, Leandro Mena, William L. Yarber, Stephanie A. Sanders, Robin R. Milhausen, Angelica Geter

Health, Behavior & Society Faculty Publications

This study investigated whether intact young Black MSM differed from their circumcised counterparts regarding condom use behaviors and perceptions and HIV/Chlamydia/gonorrhea. Young Black MSM completed a self-interview, including a pictorial item assessing circumcision status and measures of condom use. Twenty-seven percent of 388 participants reported not being circumcised. With one exception, no associations tested approached significance. The mean frequency of unprotected insertive anal sex for circumcised men was about twice as high compared to those intact (P = .04). Intact young Black MSM did not differ from circumcised men relative to prevalence of STIs (including HIV) or condom use behaviors …

E-Cigarette Use Among Women Of Reproductive Age: Impulsivity, Cigarette Smoking Status, And Other Risk Factors., Laura L. Chivers, Dennis J. Hand, Jeff S. Priest, Stephen T. Higgins

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 …

Ambivalence: Prerequisite For Success In Motivational Interviewing With Adolescents?, Sarah W. Feldstein Ewing, Timothy R. Apodaca, Jacques Gaume

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND AND AIMS: The exploration and resolution of ambivalence play an essential role in motivational interviewing (MI) theory. However, most adolescent MI studies have not examined ambivalence as a contributor to behaviour change. This paper reviewed research findings on the role of ambivalence in the adolescent change process.

METHODS AND RESULTS: We undertook a narrative review of the published empirical and theoretical literature on ambivalence and mechanisms of change in MI for adolescents and found that current MI evaluations appear not to have access to reliable and valid measures of ambivalence in adolescence or neuroimaging methods to evaluate the mechanisms …

A Pilot Study Of Comparison Gesture Analysis In Motion Driven Video Games, Fabrizio Valerio Covone, Brian Vaughan, Charlie Cullen

Conference Papers

This study investigates whether there are significant differences in the gestures made by gamers and non-gamers whilst playing commercial games that employ gesture inputs. Specifically, the study focuses on testing a prototype of multimodal capture tool that we used to obtain real-time audio, video and skeletal gesture data. Additionally, we developed an experimental design framework for the acquisition of spatio-temporal gesture data and analysed the vector magnitude of a gesture to compare the relative displacement of each participant whilst playing a game.

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …
