Engagement in online social network-delivered weight loss interventions is a predictor of weight loss. Incentivizing engagement in a subset of participants may increase group engagement and subsequent weight loss. In a pilot feasibility trial, 56 adults with obesity were randomized to two Facebook-delivered weight loss interventions, one had 10% users incentivized to engage daily and the other did not. We compared conditions on engagement and weight loss, and then compared incentivized users and natural high engagers on weight loss. Participants were 46.3 (SD: 10.3) years and 89% female. The incentivized user condition had greater total engagement (p=0 ...

UMass Worcester PRC Publications

Obesity is one of the top health issues around the globe. Rapid adoption of smartphones presents an opportunity for delivering technology-based interventions that are designed to tackle behaviors that contribute to weight gain. Research shows that the vast majority of weight loss apps in the market place do not go beyond deploying tracking based strategies that are burdensome to the users. In this study, we present a new mobile app and an intervention system called SlipBuddy that puts less burden on users and implements stimulus control strategy to help users lose weight. We describe the SlipBuddy system in detail and ...


Petrochemical Plant Console Operator Workload:The Issues, David A. Strobhar 2017 Beville Engineering Ltd.

Petrochemical Plant Console Operator Workload:The Issues, David A. Strobhar

2017

The console operators of certain petrochemical processes must maintain high levels of performance during process upsets or endanger personnel safety and the environment. Mismanagement of an upset can result in explosions, fires, and the release of hazardous chemicals to the environment. The change in workload from steady state to upset operation is significant, with alarms and control changes that are of an order of magnitude. This paper describes the state of console activity in process plants, particularly the increase with key upsets. Quantitative data on the nature of the console operator’s position, its workload during normal operation, and the ...


Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown 2017 Heriot-Watt University

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

2017

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 System To Monitor Cognitive Workload In Naturalistic High-Motion Environments, Bethany K. Bracken, Seth Elkin-Frankston, Noa Palmon, Michael Farry, Blaise de B Frederick 2017 Charles River Analytics

A System To Monitor Cognitive Workload In Naturalistic High-Motion Environments, Bethany K. Bracken, Seth Elkin-Frankston, Noa Palmon, Michael Farry, Blaise De B Frederick

2017

Across many careers, individuals face alternating periods of high and low attention and cognitive workload can impair cognitive function and undermine job performance. We have designed and are developing an unobtrusive system to Monitor, Extract, and Decode Indicators of Cognitive Workload (MEDIC) in naturalistic, high-motion environments. MEDIC is designed to warn individuals, teammates, or supervisors when steps should be taken to augment cognitive readiness. We first designed and manufactured a forehead sensor device that includes a custom fNIRS sensor and a three-axis accelerometer designed to be mounted on the inside of a baseball cap or headband, or standard issue gear ...

A Pilot Study Into Bio-Behavioural Measurements On Air Traffic Controllers In Remote Tower Operations, Tanja Bos, Rolf Zon, Eszter Furedi, Dezso Dudas, Daniel Rohacs

2017

What is the impact of shifting to remote tower operations on the Air Traffic Controller? In the joint HungaroControl-Netherlands Aerospace Centre NLR pilot project an assessment of bio-behaviour on three air traffic controllers was made in a remote tower and conventional tower. The research is motivated by HungaroControl’s plans in shifting to remote tower operations at Budapest airport in the upcoming years. This pilot project is considered a feasibility study to investigate if an eye tracker and a heart rate sensor can be used to derive workload, the controllers’ division of attention over information elements, and scanning strategies in ...


System Identification Of Motion Artifact: Noise In Eeg Headsets From Locomotion, Kaela Shea, James Tung 2017 University of Waterloo, Canada

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

2017

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 2017 University of Granada

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

2017

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 ...

Facing Human Workload: The Resilient Ego: A Psychoanalytic Point Of View, Glauco Maria Genga, Maria Gabriella Pediconii 2017 Dublin Institute of Technology

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

2017

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 ...


Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini 2017 LOGOS Ricerca & Innovazione, Florence

Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini

2017

The main aim of the article is to build a method to assess risk perception in real time in order to early detect and prevent risk behaviors and possible human errors. To this end, the relation between mental workload and stress as critical factors affecting risk perception has been investigated. In particular the mental-physical activation generated by an increment of the workload has the effect of reducing the resources needed to perceive risk increasing the worker vulnerability. The complexity of the stress phenomenon suggested the adoption of an integrated view. The Functional Model has been adopted to for its holistic ...


Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst 2017 NLR-Netherlands Aerospace Centre

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

2017

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 ...

He Repercussions Of Childhood Trauma On Posttraumatic Stress: The Mediating Effects Of Dissociation And Emotion Dysregulation, Jessica A. Ward

ETD Archive

The present study explored the mediating effects of dissociation and emotion dysregulation on the relationship between different types of childhood trauma and symptoms of posttraumatic stress. Participants were 181 undergraduate students at Cleveland State University, who competed measures of childhood trauma (emotional abuse, physical abuse, sexual abuse, and general trauma), posttraumatic stress symptoms, dissociation, and emotion dysregulation. Multiple mediation analyses were conducted to examine the model proposed in this study. The results of this study revealed that all trauma types significantly predicted adulthood posttraumatic stress. The relationship between emotional abuse and posttraumatic stress was mediated through both dissociation and emotion ...


Internalizing And Externalizing Dysfunction: An Integrative Model Of Adolescent Drinking, Leila Guller 2017 University of Kentucky

Internalizing And Externalizing Dysfunction: An Integrative Model Of Adolescent Drinking, Leila Guller

Theses and Dissertations--Psychology

Separate externalizing and internalizing pathways to problem drinking have been described. However, internalizing and externalizing are substantially correlated, thus, there is good reason to believe that these two forms of dysfunction behaviors do not operate independently.

We tested an integrative developmental model of transactions among internalizing symptomatology, externalizing personality, and psychosocial learning in the prediction of both drinking problems and future internalizing symptoms. To do so, we studied a large sample (n = 1910, 49.9% female) of children over a critical developmental period, from the spring of 5th (last year elementary school) grade through the spring of 9th grade (first ...


The Effects Of Superordinate Identity Recategorization And Social Value Orientation On Ethical Decision-Making In A Business Dilemma, Thomas Steven Colville 2017 Loyola University Chicago

The Effects Of Superordinate Identity Recategorization And Social Value Orientation On Ethical Decision-Making In A Business Dilemma, Thomas Steven Colville

Master's Theses

The purpose of the present study was to investigate potential solutions to the prevalence of unethical behavior in groups, specifically through the use of superordinate recategorization. Superordinate recategorization allows group members to feel an affinity with others not typically included in their in-group. This should promote ethical decision-making by enabling the inherent in-group favoring tendencies found in groups to be extended to a more inclusive category. In the context of the present study, the ethicality of participants' behavior in the Panalba scenario was determined by their choices on a 1 to 6 scale from least to most ethical. Additionally, participants ...

PURPOSE: The purpose of this study was to evaluate student feedback of the 2015 Lifelines Suicide Prevention Program at Jessie Clark Middle School. Student feedback was examined by assessing students’ knowledge of suicide, attitudes toward suicide, knowledge of when and from whom to seek help if feeling suicidal or told by a friend that they are suicidal, and impressions of the educational presentation following participation in the Lifelines Suicide Prevention Program.

METHODS: In this secondary analysis, anonymous student responses (N=269) from a 2015 middle school survey were examined by using a mixed method design with the quantitative study measures ...


To Nudge Or Not To Nudge: Promoting Environmentally Beneficial Behaviors, Emma Jean Cooper 2017 Bard College

To Nudge Or Not To Nudge: Promoting Environmentally Beneficial Behaviors, Emma Jean Cooper

Bard Center for Environmental Policy

In order to mitigate the effects of climate change, humans need to change how they act toward the environment. Unfortunately, as much as we may want to act in ways that would be best for us and for the environment, we often struggle to do just that due to cognitive biases. Nudge theory attempts to remedy this problem by helping us make the decision that would be in our best interests. To explore this issue, I conduct an extended review of the literature to examine how well nudge theory can be applied to the realm of environmental policy. Specifically, I ...


The Influence Of Genetic And Environmental Factors On Quit Attempt In Adolescent And Young Adult Twins, Gladys Langi 2017 Virginia Commonwealth University

The Influence Of Genetic And Environmental Factors On Quit Attempt In Adolescent And Young Adult Twins, Gladys Langi

Theses and Dissertations

The purpose of this study was to examine the genetic and environmental influences on lifetime quit attempt in three US adolescent and young adult twin samples (N total = 6,322). The study utilized a common-contingent-causal (CCC) model to estimate these factors for lifetime quit attempts, after accounting for the factors for lifetime cigarette use and cigarettes per day. The study also examined age and sex differences, as well as the degree of relationship between these smoking phenotypes. The results demonstrated significant genetic influences for lifetime quit attempts in adolescents and young adults. No sex differences were observed for the contributions ...


Individual Differences In Executive (Dys)Function In Relation To Sleep Duration And Psychopathology, Chelsie E. Benca 2017 University of Colorado at Boulder

Individual Differences In Executive (Dys)Function In Relation To Sleep Duration And Psychopathology, Chelsie E. Benca

Psychology and Neuroscience Graduate Theses & Dissertations

This dissertation presents four studies that examined how executive functions (EFs) relate to problematic behaviors, such as psychopathology and atypical sleep, as well as how EFs are characterized in healthy individuals. The first study examined whether genetic risk for five different forms of psychopathology predicted EFs at the latent variable level in a population sample. The second study characterized the neural activation patterns in health individuals in response to 3 different types of EF tasks. This study (a) assessed the overlapping activation elicited across the different EF task types, and (b) used neural activation to predict high or low EF ...


Addiction, Choice And Criminal Law, Stephen J. Morse 2017 University of Pennsylvania Law School

Addiction, Choice And Criminal Law, Stephen J. Morse

Faculty Scholarship

This chapter is a contribution to a volume, Addiction and Choice, edited by Nick Heather and Gabriel Segal that is forthcoming from Oxford University Press. Some claim that addiction is a chronic and relapsing brain disease; others claim that it is a product of choice; yet others think that addictions have both disease and choice aspects. Which of these views holds sway in a particular domain enormously influences how that domain treats addictions. With limited exceptions, Anglo-American criminal law has implicitly adopted the choice model and a corresponding approach to responsibility. Addiction is irrelevant to the criteria for the prima ...
