Ethical Decision Making Behind The Wheel – A Driving Simulator Study, Siby Samuel, Sarah Yahoodik, Yusuke Yamani, Krishna Valluru, Donald L. Fisher

Psychology Faculty Publications

Over the past several years, there has been considerable debate surrounding ethical decision making in situations resulting in inevitable casualties. Given enough time and all other things being equal, studies show that drivers will typically decide to strike the fewest number of pedestrians in scenarios where there is a choice between striking several versus one or no pedestrians. However, it is unclear whether drivers behave similarly under situations of time pressure. In our experiment in a driving simulator, 32 drivers were given up to 2 s to decide which group of pedestrians to avoid among groups of larger (5) or …

Successfully Aging At Work Or Successfully Working While Aging? The Importance Of Older Workers' Psychological Well-Being, William P. Jimenez

Psychology Faculty Publications

Frank, 62, has been working at the same company for the past 32 years. His strong work ethic, subject-matter expertise, and continued excellent performance have saved him from several waves of layoffs and restructuring. Over the years Frank has become cynical. Gradually, many of Frank’s close colleagues were let go, and he has had difficulty connecting with newer employees. Although he is not particularly happy at his job, Frank is determined to continue working for his employer until at least 66, which is when he can start collecting Social Security benefits without penalty.

The Rise, Fall, And Repair Of Trust For Automated Driving Systems, Scott Mishler, Jing Chen

Psychology Faculty Publications

The purpose of this study was to investigate how human driver's trust in the automated driving system is built over time and affected by automation failure. The study expanded trust development over time by measuring trust after a practice demonstration ofthe system capabilities and after each of seven unique, sequential drives. The automation performed perfectly on six of the seven drives but made one of three different responses to a critical hazard event in the fourth drive. Depending on the error-type condition, the automation either perfectly avoided the hazard (no error), issued a takeover request (TOR), or failed to notice …

Psychology Faculty Publications

Objective

The present study aimed to determine whether the momentary severity of women's somatic symptoms was concurrently and prospectively associated with their engagement in binge eating in naturalistic settings.

Method

Thirty women (M_age = 34.13, SD = 13.92) who had engaged in binge eating at least once over the month prior to study entry completed a 14-day ecological momentary assessment (EMA) protocol. During each of the 14 days, participants received five semi-random surveys via text message that assessed momentary somatic symptom severity (i.e., headaches, stomachaches/pain, chest/heart pain, faintness/dizziness, shortness of breath, fatigue) and disordered eating behaviors. Generalized estimating equations …

An Ecological Momentary Assessment Of Self-Improved And Self-Evaluation Body Comparisons: Associations With College Women's Body Dissatisfaction And Exercise, Rachel I. Macintyre, Kristin E. Heron, Abby L. Braitman, Danielle Arigo

Psychology Faculty Publications

Upward body comparisons are prevalent among college women and associated with body dissatisfaction and disordered eating. However, less is known about distinguishing features of the comparisons themselves as they occur in daily life. The primary purpose of the present study was to examine whether two types of upward body comparisons previously studied experimentally (self-improvement and self-evaluation) are differentially associated with body- and exercise-related outcomes in real-life settings using ecological momentary assessment (EMA). Undergraduate women (N = 74) between 18-25 years (Mage = 20.4, SD = 1.63) completed five surveys on smartphones daily for seven days. EMA measures …

Ecosystem Services And Disservices Of Mangrove Forests And Salt Marshes, Daniel A. Friess, Erik S. Yando, Jahson B. Alemu I, Lynn-Wei Wong, Sasha D. Soto, Natasha Bhatia, S. J. Hawkins (Ed.), A. L. Allcock (Ed.), A. E. Bates (Ed.), A.J. Evans (Ed.), L. B. Firth (Ed.), C. D. Mcquaid (Ed.), B. D. Russell (Ed.), I. P. Smith (Ed.), S. E. Swearer (Ed.), P. A. Todd (Ed.)

Biological Sciences Faculty Publications

Coastal wetlands such as mangrove forests and salt marshes provide a range of important benefits to people, broadly defined as ecosystem services. These include provisioning services such as fuelwood and food, regulating services such as carbon sequestration and wave attenuation, and various tangible and intangible cultural services. However, strong negative perceptions of coastal wetlands also exist, often driven by the perceived or actual ecosystem disservices that they also produce. These can include odour, a sense of danger, and their real or perceived role in vector and disease transmission (e.g. malaria). This review provides an introduction to the ecosystem services and …

A Heuristic Baseline Method For Metadata Extraction From Scanned Electronic Theses And Dissertations, Muntabir H. Choudhury, Jian Wu, William A. Ingam, Edward A. Fox

Computer Science Faculty Publications

Extracting metadata from scholarly papers is an important text mining problem. Widely used open-source tools such as GROBID are designed for born-digital scholarly papers but often fail for scanned documents, such as Electronic Theses and Dissertations (ETDs). Here we present a preliminary baseline work with a heuristic model to extract metadata from the cover pages of scanned ETDs. The process started with converting scanned pages into images and then text files by applying OCR tools. Then a series of carefully designed regular expressions for each field is applied, capturing patterns for seven metadata fields: titles, authors, years, degrees, academic programs, …

Repurposing Visual Input Modalities For Blind Users: A Case Study Of Word Processors, Hae-Na Lee, Vikas Ashok, I.V. Ramakrishnan

Computer Science Faculty Publications

Visual 'point-and-click' interaction artifacts such as mouse and touchpad are tangible input modalities, which are essential for sighted users to conveniently interact with computer applications. In contrast, blind users are unable to leverage these visual input modalities and are thus limited while interacting with computers using a sequentially narrating screen-reader assistive technology that is coupled to keyboards. As a consequence, blind users generally require significantly more time and effort to do even simple application tasks (e.g., applying a style to text in a word processor) using only keyboard, compared to their sighted peers who can effortlessly accomplish the same tasks …

Towards Making Videos Accessible For Low Vision Screen Magnifier Users, Ali Selman Aydin, Shirin Feiz, Vikas Ashok, Iv Ramakrishnan

Computer Science Faculty Publications

People with low vision who use screen magnifiers to interact with computing devices find it very challenging to interact with dynamically changing digital content such as videos, since they do not have the luxury of time to manually move, i.e., pan the magnifier lens to different regions of interest (ROIs) or zoom into these ROIs before the content changes across frames.

In this paper, we present SViM, a first of its kind screen-magnifier interface for such users that leverages advances in computer vision, particularly video saliency models, to identify salient ROIs in videos. SViM's interface allows users to zoom in/out …

Sail: Saliency-Driven Injection Of Aria Landmarks, Ali Selman Aydin, Shirin Feiz, Vikas Ashok, Iv Ramakrishnan

Computer Science Faculty Publications

Navigating webpages with screen readers is a challenge even with recent improvements in screen reader technologies and the increased adoption of web standards for accessibility, namely ARIA. ARIA landmarks, an important aspect of ARIA, lets screen reader users access different sections of the webpage quickly, by enabling them to skip over blocks of irrelevant or redundant content. However, these landmarks are sporadically and inconsistently used by web developers, and in many cases, even absent in numerous web pages. Therefore, we propose SaIL, a scalable approach that automatically detects the important sections of a web page, and then injects ARIA landmarks …

Rotate-And-Press: A Non-Visual Alternative To Point-And-Click, Hae-Na Lee, Vikas Ashok, I. V. Ramakrishnan

Computer Science Faculty Publications

Most computer applications manifest visually rich and dense graphical user interfaces (GUIs) that are primarily tailored for an easy-and-efficient sighted interaction using a combination of two default input modalities, namely the keyboard and the mouse/touchpad. However, blind screen-reader users predominantly rely only on keyboard, and therefore struggle to interact with these applications, since it is both arduous and tedious to perform the visual 'point-and-click' tasks such as accessing the various application commands/features using just keyboard shortcuts supported by screen readers.

In this paper, we investigate the suitability of a 'rotate-and-press' input modality as an effective non-visual substitute for the visual …

The model with 19 features achieves F₁=85.6%. SCC supports PDF, XML, and JSON files out-of-box, provided that they are conformed to certain schemas. The API supports single document processing and batch processing in parallel. It takes about 12–45 seconds on average depending on the format to process a …

Acknowledgement Entity Recognition In Cord-19 Papers, Jian Wu, Pei Wang, Xin Wei, Sarah Rajtmajer, C. Lee Giles, Christopher Griffin

Computer Science Faculty Publications

Acknowledgements are ubiquitous in scholarly papers. Existing acknowledgement entity recognition methods assume all named entities are acknowledged. Here, we examine the nuances between acknowledged and named entities by analyzing sentence structure. We develop an acknowledgement extraction system, AckExtract based on open-source text mining software and evaluate our method using manually labeled data. AckExtract uses the PDF of a scholarly paper as input and outputs acknowledgement entities. Results show an overall performance of F₁=0.92. We built a supplementary database by linking CORD-19 papers with acknowledgement entities extracted by AckExtract including persons and organizations and find that only up to …

The Influence Of Neural Reward Processing On Memory In Depression, Nathan M. Hager

Psychology Theses & Dissertations

Theories and research suggest that depression involves impaired reward sensitivity and a deficit in memory for rewarding stimuli. Some researchers propose that this memory deficit may result from reduced neural reward sensitivity, which impairs the encoding of reward-related memories, but few studies have directly probed this connection. Such research may benefit from examining the reward positivity (RewP), an event-related potential (ERP) previously linked to reduced reward sensitivity in depression. Undergraduates with high or low self-reported depression completed a task in which they chose one of three doors, revealing a neutral word written in a color which indicated an outcome of …

Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers

Psychology Theses & Dissertations

Research on the effects of interruptions shows that they can be either costly or beneficial depending on which aspects of an interruption are manipulated. One important aspect that contributes to these conflicting results concerns when an interruption occurs. The present study explored how event segmentation theory (EST) can be used to determine optimal moments for an interruption relying on hierarchical task analysis (HTA) to identify coarse and fine event boundaries. Utilizing a 2 X 3 mixed design, undergraduate students completed a trip planning task divided into three task trials. The within-subjects factor was interruption timing, which had three levels: none, …

A Transformative Concept: From Data Being Passive Objects To Data Being Active Subjects, Hans-Peter Plag, Shelley-Ann Jules-Plag

OES Faculty Publications

The exploitation of potential societal benefits of Earth observations is hampered by users having to engage in often tedious processes to discover data and extract information and knowledge. A concept is introduced for a transition from the current perception of data as passive objects (DPO) to a new perception of data as active subjects (DAS). This transition would greatly increase data usage and exploitation, and support the extraction of knowledge from data products. Enabling the data subjects to actively reach out to potential users would revolutionize data dissemination and sharing and facilitate collaboration in user communities. The three core elements …

High-Resolution Intertidal Topography From Sentinel-2 Multi-Spectral Imagery: Synergy Between Remote Sensing And Numerical Modeling, Md Jamal Uddin Khan, Md Nazmuddoha Ansary, Fabien Durand, Laurent Testut, Marufa Ishaque, Stéphane Calmant, Yann Krien, A.K.M. Saiful Islam, Fabrice Papa

OES Faculty Publications

The intertidal zones are well recognized for their dynamic nature and role in near-shore hydrodynamics. The intertidal topography is poorly mapped worldwide due to the high cost of associated field campaigns. Here we present a combination of remote-sensing and hydrodynamic modeling to overcome the lack of in situ measurements. We derive a digital elevation model (DEM) by linking the corresponding water level to a sample of shorelines at various stages of the tide. Our shoreline detection method is fully automatic and capable of processing high-resolution imagery from state-of-the-art satellite missions, e.g., Sentinel-2. We demonstrate the use of a tidal model …

The G5 Sahel: An Insufficient Organization For A Failed Region?, Beder Dine El Khou

Graduate Program in International Studies Theses & Dissertations

In the wake of mass kidnapping and terrorist attacks launched by Boko Haram and other extremist groups in the Sahel of West Africa, along with the rise of the Islamic State in Libya that started to have immediate impact on the Sahel’s already problematic situation, five states from the region of Sahel decided to create a coalition in 2014 not only to fight insurgencies rampaging in the area but also to work on the development of the region. With a very small capacity in terms of man power and equipment, the G5 Sahel coalition attempts to achieve what other intervening …

Aberrant Epigenomic Modulation Of Glucocorticoid Receptor Gene (Nr3c1) In Early Life Stress And Major Depressive Disorder Correlation: Systematic Review And Quantitative Evidence Synthesis, Laurens Holmes Jr., Emily Shutman, Chinacherem Chinaka, Kerti Deepika, Lavisha Palaez, Kirk W. Dabney

Community & Environmental Health Faculty Publications

Early life stress (ELS) induced by psychological trauma, child maltreatment, maternal separation, and domestic violence predisposes to psycho-behavioral pathologies during adulthood, namely major depressive disorder (MDD), anxiety, and bipolar affective disorder. While environmental data are available in illustrating this association, data remain to be established on the epigenomic underpinning of the nexus between ELS and MDD predisposition. Specifically, despite the observed aberrant epigenomic modulation of the NR3C1, a glucocorticoid receptor gene, in early social adversity and social threats in animal and human models, reliable scientific data for intervention mapping in reducing social adversity and improving human health is required. We …

Integrating Geochronologic And Instrumental Approaches Across The Bengal Basin, Elizabeth L. Chamberlain, Steven L. Goodbred, Richard Hale, Michael S. Steckler, Jakob Willinga, Carol Wilson

OES Faculty Publications

Constraining time is of critical importance to evaluating the rates and relative contributions of processes driving landscape change in sedimentary basins. The geomorphic character of the field setting guides the application of geochronologic or instrumental tools to this problem, because the viability of methods can be highly influenced by geomorphic attributes. For example, sediment yield and the linked potential for organic preservation may govern the usefulness of radiocarbon dating. Similarly, the rate of sediment transport from source to sink may determine the maturity and/or light exposure of mineral grains arriving in the delta and thus the feasibility of luminescence dating. …

Political Science & Geography Faculty Publications

A new 30-m spatial resolution global shoreline vector (GSV) was developed from annual composites of 2014 Landsat satellite imagery. The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, resulting in a new characterisation of the number and size of global islands. Three size classes of islands were mapped: continental mainlands (5), islands greater than 1 km² (21,818), and islands smaller than 1 km² (318,868). The GSV represents the shore zone land and water interface boundary, and …

The Flow Of Family Transitions Of Australian Families, Shana Pribesh, Matthew Usevitch, Elizabeth Koch Sigler, Kaijsa Angerhofer Heninger, Yuanyuan Yue, Mikaela J. Dufur, Jonathan A. Jarvis

Educational Leadership & Workforce Development Faculty Publications

Family structure disruption has been linked to negative child educational and health outcomes (Perales et al. 2016). Australia has relatively stable families, but income disparities between Australians are widening, and single-parent families make up a large proportion of families living in poverty. Cohabitation is also common in Australia with approximately three-quarters of marriages preceded by cohabitation. If substantial family structure churning affects Australian children this may expose a need for special policy interventions aimed at family creation and dissolution to ameliorate the negative effects of such stressful experiences. To highlight family structures and transitions Australian children experience, we use Sankey …
