Leaking Women: A Genealogy Of Gendered And Racialized Flow, Michelle Fine Feb 2019

Leaking Women: A Genealogy Of Gendered And Racialized Flow, Michelle Fine

Publications and Research

Through a feminist and critical race analytic, this paper theorizes the disruptions evoked by leaky women—actually doubly leaky women—those whose nipples, peri-menopausal uterus’ and mouths have “leaked” in ways that rupture/stain/expose the white-patriarchal-capitalist enclosure of work, home and the streets and then dared to leak again by suing for justice in court. In a closing coda, I address the race/class policing dynamics between she who leaks and the “respectable” [usually white] women recruited to plaster up the hole and cauterize the leaker.

Automation-Induced Complacency Potential: Development And Validation Of A New Scale, Stephanie Merritt, Alicia Ako-Brew, William Bryant, Amy Staley, Michael Mckenna, Austin Leone, Lei Shirase Feb 2019

Automation-Induced Complacency Potential: Development And Validation Of A New Scale, Stephanie Merritt, Alicia Ako-Brew, William Bryant, Amy Staley, Michael Mckenna, Austin Leone, Lei Shirase

Psychology Faculty Works

Complacency, or sub-optimal monitoring of automation performance, has been cited as a contributing factor in numerous major transportation and medical incidents. Researchers are working to identify individual differences that correlate with complacency as one strategy for preventing complacency-related accidents. Automation-induced complacency potential is an individual difference reflecting a general tendency to be complacent across a wide variety of situations which is similar to, but distinct from trust. Accurately assessing complacency potential may improve our ability to predict and prevent complacency in safety-critical occupations. Much past research has employed an existing measure of complacency potential. However, in the 25 years since …

Brain and Mind Institute Researchers' Publications

© 2019 Elsevier Ltd Although a memory systems view of the medial temporal lobe (MTL) has been widely influential in understanding how memory processes are implemented, a large body of work across humans and animals has converged on the idea that the MTL can support various other decisions, beyond those involving memory. Specifically, recent work suggests that perception of and memory for visual representations may interact in order to support ongoing cognition. However, given considerations involving lesion profiles in neuropsychological investigations and the correlational nature of fMRI, the precise nature of representations supported by the MTL are not well understood …

Towards Quantifiable Metrics Warranting Industry-Wide Corporate Death Penalties, Joshua M. Pearce Feb 2019

Towards Quantifiable Metrics Warranting Industry-Wide Corporate Death Penalties, Joshua M. Pearce

Department of Materials Science and Engineering Publications

In the singular search for profits, some corporations inadvertently kill humans. If this routinely occurs throughout an industry, it may no longer serve a net positive social purpose for society and should be eliminated. This article provides a path to an objective quantifiable metric for determining when an entire industry warrants the corporate death penalty. First, a theoretical foundation is developed with minimum assumptions necessary to provide evidence for corporate public purposes. This is formed into an objective quantifiable metric with publicly-available data and applied to two case studies in the U.S.: the tobacco and coal mining industries. The results …

The Weathering Hypothesis: Sociocultural And Biological Factors Of Postpartum Depression Among Black Women, Anna Van Beusekom Feb 2019

The Weathering Hypothesis: Sociocultural And Biological Factors Of Postpartum Depression Among Black Women, Anna Van Beusekom

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Black women experience higher rates of PPD than their White counterparts. To date, no one has linked experiences of racism and discrimination, the impacts racism and discrimination have on allostatic load, and the subsequent process of weathering to the elevated levels of PPD in Black women. However, the Weathering Hypothesis can be utilized to explain the higher rates of PPD seen in Black women via the interactions between sociocultural factors and biological factors.

Guinn, Robert Thomas, Jennifer E. Thropp, Jayde King, Yolanda Ortiz, Jessica Cruit, Nicholas Defilippis, Krijn Berendschot, Jacqueline Mcsorley, John Kleber

General Aviation Weather Display Interpretation

Prior research has indicated that general aviation (GA) pilots may lack adequate knowledge of aviation weather concepts and skill at interpreting aviation weather displays. Therefore, the purpose of the current project was to develop and validate a comprehensive set of aviation weather knowledge and interpretation multiple-choice questions, and in turn, to use the questions to assess pilot understanding of aviation weather concepts and displays. An interdisciplinary research team that included two meteorologists, one Gold Seal Certificated Flight Instructor (CFI), a human factors psychologist, and several human factors graduate students performed this research.

To Excuse Or Not To Excuse: Effect Of Explanation Type And Provision On Reactions To A Workplace Behavioral Transgression, Joseph Mroz Feb 2019

To Excuse Or Not To Excuse: Effect Of Explanation Type And Provision On Reactions To A Workplace Behavioral Transgression, Joseph Mroz

Psychology Faculty Publications

People often offer an excuse or an apology after they do something wrong. In this paper, we examine how giving an excuse, an apology, or no explanation after arriving late to a meeting influences the attitudes and behavioral intentions others form toward the late arrival. Additionally, we examined how a group-related factor (complaining) and the late arrival’s history with coming late affected participant judgments. Across two studies using complementary experimental and survey methods, we found that an excuse is better than no explanation, but that the difference between apology and no explanation and apology and excuse is not always clear. …

My Problems Are Solvable: Idiographic Methods Offset Age Differences In Interpersonal Problem Solving Among Young, Middle-Aged, And Older Adults, Daniele Artistico, Daniel Cervone, Carolina Montes Garcia

Publications and Research

This study tested the hypothesis that older adults retain high levels of everyday problem solving performance when confronting problems of maximal ecological relevance, identified through idiographic methods. Younger, middle-aged, and older adults completed a daily challenge questionnaire (DCQ) in which they reported problems of maximal personal relevance or idiographic problems. The large majority of the problems reported were interpersonal. We then assessed performance on an everyday problem-solving task in which participants generated solutions for idiographic problems as well as problems generated by group matched research participants representing each of two other age groups (e.g., older adults received their own problems …

Farm Animal Cognition—Linking Behavior, Welfare And Ethics, Christian Nawroth, Jan Langbein, Marjorie Coulon, Vivian Gabor, Susan Oesterwind, Judith Benz-Schwarzburg, Eberhard Von Borell

Social Cognition Collection

Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on ungulate livestock species, such as cattle, horses, …

Multifractality Of Posture Modulates Multisensory Perception Of Stand-On-Ability, Jonathan K. Doyon, Alen Hajnal, Tyler Surber, Joseph D. Clark, Damian G. Kelty-Stephen Feb 2019

Multifractality Of Posture Modulates Multisensory Perception Of Stand-On-Ability, Jonathan K. Doyon, Alen Hajnal, Tyler Surber, Joseph D. Clark, Damian G. Kelty-Stephen

Faculty Publications

By definition, perception is a multisensory process that unfolds in time as a complex sequence of exploratory activities of the organism. In such a system perception and action are integrated, and multiple energy arrays are available simultaneously. Perception of affordances interweaves sensory and motor activities into meaningful behavior given task constraints. The present contribution offers insight into the manner in which perception and action usher the organism through competent functional apprehension of its surroundings. We propose that the tensegrity structure of the body, manifested via multifractality of exploratory bodily movements informs perception of affordances. The affordance of stand-on-ability of ground …

Identification And Transformation Difficulty In Problem Solving: Electrophysiological Evidence From Chunk Decomposition, Zhonglu Zhang, Yu Luo, Chaolun Wang, Christopher M. Warren, Qi Xia, Qiang Xing, Bihua Cao, Yi Lei, Hong Li Feb 2019

Identification And Transformation Difficulty In Problem Solving: Electrophysiological Evidence From Chunk Decomposition, Zhonglu Zhang, Yu Luo, Chaolun Wang, Christopher M. Warren, Qi Xia, Qiang Xing, Bihua Cao, Yi Lei, Hong Li

Psychology Faculty Publications

A wealth of studies have investigated how to overcome experience-based constraints in creative problem solving. One such experience-based constraint is the tendency for people to view tightly organized visual stimuli as single, unified percepts, even when decomposition of those stimuli into component parts (termed chunk decomposition) would facilitate problem solving. The current study investigates the neural underpinnings of chunk decomposition in creative problem solving by analyzing event-related potentials. In two experiments, participants decomposed Chinese characters into the character’s component elements and then used the base elements to form a new valid character. The action could require decomposing a “tight” chunk, …

Psychology: Faculty Scholarship

Developmental dyslexia (DD) is one of the most prevalent learning disorders, with high impact on school and psychosocial development and high comorbidity with conditions like attention-deficit hyperactivity disorder (ADHD), depression, and anxiety. DD is characterized by deficits in different cognitive skills, including word reading, spelling, rapid naming, and phonology. To investigate the genetic basis of DD, we conducted a genome-wide association study (GWAS) of these skills within one of the largest studies available, including nine cohorts of reading-impaired and typically developing children of European ancestry (N = 2562–3468). We observed a genome-wide significant effect (p <  1 × 10−8) on rapid automatized naming of letters (RANlet) for variants on 18q12.2, within MIR924HG (micro-RNA …

Relational Thriving In Context: Examining The Roles Of Gratitude, Affectionate Touch, And Positive Affective Variability In Health And Well-Being, Alicia Rochelle Starkey

Dissertations and Theses

Social connection is important to one's health and longevity. However, not only do people need others to survive, we need others to thrive. Researchers call for deeper examination of the functions and processes through which our social partners help us to prosper and thrive, such as through increased physical health and well-being. Over three studies, I examined phenomena theorized to contribute to long-term thriving including positive emotions (i.e., gratitude and positive affect fluctuation), responsive support, affectionate touch, and physical health (i.e., sleep) within the context of nursing work (Study 1) and military relationships (Study 2 & 3). Study 1 provides …

Why Does Coaching Work? An Examination Of Inputs And Process Variables In An Employee Coaching Program, Sarah E. Frick Feb 2019

Why Does Coaching Work? An Examination Of Inputs And Process Variables In An Employee Coaching Program, Sarah E. Frick

USF Tampa Graduate Theses and Dissertations

The efficacy of leadership coaching to improve leader and organizational outcomes cannot be overstated. However, a thorough understanding of some of the inputs and process variables involved in coaching has not been empirically established to date. To address this issue in the leader development and coaching literature, I examined the characteristics of the coaches and the coachees and their relationships with two relational variables potentially involved in coaching relationships (i.e., leader-member exchange and trust). The importance of leadership to work outcomes and leader development is highlighted, followed by a discussion of the specific leader development technique of coaching. The discussion …

Categorization Of Exam Questions To Improve Metacognition, Tiffany Barrett Feb 2019

Categorization Of Exam Questions To Improve Metacognition, Tiffany Barrett

UNLV Best Teaching Practices Expo

This practice addresses UNLV students’ need for greater metacognitive awareness. Students often employ memorization as a study strategy when preparing for an exam. This can create an inability to apply the knowledge in a complex or different scenario. We know that “practice retrieving” study activities produce greater gains in meaningful learning (Karpicke 2011) but often students don’t identify a need for a change in study habits and a deeper level of understanding, especially if their exam score is considered passing.

Understanding The Experiences Of Latino Community College Students On Academic Probation: A Case Study, Maria P. Mcpherson

CUP Ed.D. Dissertations

The academic standards and policies of institutions of higher education consider student underachievement, among the other aspects of education. Academic standing addresses the probation status designed to intervene and inform students who are unable to meet certain academic institutional standards. However, there is a lack of research discussing the experiences of community college students on academic probation (AP). This qualitative case study explored the perceptions of Latino college students experiences with AP at a large community college on the west coast of the United States. Specifically, the transitions of Latino students to college as previous studies have demonstrated that their …

Intrinsic Functional Boundaries Of Lateral Frontal Cortex In The Common Marmoset Monkey, David J. Schaeffer, Kyle M. Gilbert, Joseph S. Gati, Ravi S. Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

© 2019 the authors. The common marmoset (Callithrix jacchus) is a small New World primate species that has been recently targeted as a potentially powerful preclinical model of human prefrontal cortex dysfunction. Although the structural boundaries of frontal cortex were described in marmosets at the start of the 20th century (Brodmann, 1909) and refined more recently (Paxinos et al., 2012), the broad functional boundaries of marmoset frontal cortex have yet to be established. In this study, we sought to functionally derive boundaries of the marmoset lateral frontal cortex (LFC) using ultra-high field (9.4 T) resting-state functional magnetic resonance imaging (RS-fMRI). …

Adopting the framework of brain dynamics as a cornerstone of human consciousness, we determined whether dynamic signal coordination provides specific and generalizable patterns pertaining to conscious and unconscious states after brain damage. A dynamic pattern of coordinated and anticoordinated functional magnetic resonance imaging signals characterized healthy individuals and minimally conscious patients. The brains of unresponsive patients showed primarily a pattern of low interareal phase coherence mainly mediated by structural connectivity, and had smaller chances to transition between patterns. The complex pattern was further corroborated in patients with covert cognition, who could perform neuroimaging mental imagery tasks, validating this pattern’s implication …

The present study explored how motor cortical activity was influenced by visual perception of complex environments that either afforded or obstructed arm and leg reactions in young, healthy adults. Most importantly, we focused on compensatory balance reactions where the arms were required to regain stability following unexpected postural perturbation. Our first question was if motor cortical activity from the hand area automatically corresponds to the visual environment. Affordance-based priming of the motor system was assessed using single-pulse Transcranial Magnetic Stimulation (TMS) to determine if visual access to a wall-mounted support handle influenced corticospinal excitability. We evaluated if hand actions were …
