Characterizations Of Student, Instructor, And Textbook Discourse Related To Basis And Change Of Basis In Quantum Mechanics, Kaitlyn Stephens Serbin, Megan Wawro, Rebecah Storms

School of Mathematical & Statistical Sciences Faculty Publications

Communities develop social languages in which utterances take on culturally specific situated meanings. As physics students interact in their classroom, they can learn the broader physics community’s social language by co-constructing meanings with their instructors. We provide an exposition of a systematic and productive use of idiosyncratic, socially acquired language in two classroom communities that we consider to be subcultures of the broader community of physicists. We perform a discourse analysis on twelve quantum mechanics students, two instructors, and the course text related to statements about basis and change of basis within a spin-½ probability problem. We classify the utterances’ …

Follow The Scientists? How Beliefs About The Practice Of Science Shaped Covid-19 Views, Thomas G. Safford, Emily H. Whitmore, Lawrence C. Hamilton

Faculty Publications

“Follow the science” became the mantra for responding to COVID-19 pandemic. However, for the public this also meant “follow the scientists,” and this led to uneasiness as some viewed scientists as not credible. We investigate how beliefs about the way scientists develop their findings affect pandemic-related views. Our analysis shows that beliefs about scientists’ objectivity predict views regrading coronavirus-related risks, behavioral changes, and policy priorities. While political party identity also predicts views about COVID-19-related concerns, these vary by political leaders whose approaches embraced versus dismissed science based strategies, highlighting the importance of perceptions of scientists in shaping pandemic related attitudes …

Playing Together: A Call For Multiple Stakeholders To Reduce Exclusionary And Harsh Discipline For Young Bicoc With Disabilities, Saili Kulkarni

Faculty Research, Scholarly, and Creative Activity

 Punitive disciplinary actions deny Black, Indigenous,2 Children of Color (BICOC) with disabilities from access to meaningful instruction and increase their risks for truancy, dropping out, and incarceration. At the intersection of race, disability, and discipline, this paper is a call to action for research and practices that bring together stakeholders and co-constructed, local solutions to exclusionary disciplinary practices affecting BICOC with disabilities. Specifically, we assert that efforts to reduce disproportionately racist responses to the challenging behaviors of young BICOC with disabilities (birth through age 8) cannot be solved with a single intervention strategy or simplistic approaches. Instead, we highlight the …

I considered infographics as an important genre of communication during such times because they not only provided sufficient information to the audience but did so in an engaging manner. The goal of my study was to think about the role of infographics in the context of health and risk communication during a pandemic, and to emphasize on the rhetorical elements that constitute the creation of infographics by major health organizations. I specifically focused on three elements: the kinds of information communicated through infographics, …

Investigation Of The Sensitivity Of Human Arm To Small Interaction Forces During Physical Human-Robot Interaction (Phri), Fazlur Rashid

Masters Theses

“Understanding the human motor control strategy during physical interaction tasks is crucial for developing future robots for physical human-robot interaction (pHRI). Effective pHRI depends on humans communicating their intentions for movement with robots. In physical human-human interaction (pHHI), small interaction forces are known to convey their intent between the partners. It is speculated that small interaction forces contain significant information to convey the movement intention of pHHI. However, the mechanism underlying this interaction strategy is largely unknown. Hence, the aim of this work was to investigate what affects humans’ sensitivity to the interaction forces. The hypothesis was that small interaction …

For a series of images, participants identified the subject and rated their confidence level. Results …

Exploring Spatial Patterns Of Virginia Tornadoes Using Kernel Density And Space-Time Cube Analysis (1960-2019), Michael J. Allen, Thomas R. Allen, Christopher Davis, George Mcleod, Wolfgang Kainz (Ed.), Dean Kyne (Ed.)

Political Science & Geography Faculty Publications

This study evaluates the spatial-temporal patterns in Virginia tornadoes using the National Weather Service Storm Prediction Center’s Severe Weather GIS (SVRGIS) database. In addition to descriptive statistics, the analysis employs Kernel Density Estimation for spatial pattern analysis and space-time cubes to visualize the spatiotemporal frequency of tornadoes and potential trends. Most of the 726 tornadoes between 1960–2019 occurred in Eastern Virginia, along the Piedmont and Coastal Plain. Consistent with other literature, both the number of tornadoes and the tornado days have increased in Virginia. While 80% of the tornadoes occurred during the warm season, tornadoes did occur during each month …

Re-Spatializing Gangs: An Exponential Random Graph Model Of Twitter Data To Analyze The Geospatial Distribution Of Gang Member Connections, Ryan J. Roberts

Political Science & Geography Faculty Publications

Gang studies often use location-based approaches to explain gang members’ interconnectedness. Although this perspective remains consistent with the proximity principle that the smaller the geographic space, the greater the likelihood of observing connections between individuals, location-based studies limit our understanding of gang member connections to narrowly defined geographic spaces at specific points in time. The advent of social media has re-spatialized gang member interconnectedness to unbounded geographic spaces, where the preservation of online activity can extend indefinitely. Despite having an online presence, most research examining the digital footprint of gangs tends to be descriptive. This study collects Twitter data to …

Public Perception Of Adults With Adhd In The United States: Stigma Vs. Strengths, Peyton S. Barton

Dissertations and Theses @ UNI

Stigma is a stereotyped judgement of a group of people (e.g. people with a mental illness; Goffman, 1963). Mentally ill individuals are often assumed to be dangerous, irresponsible, or incapable of taking care of themselves (Rüsch et al., 2005). The type of judgement and the level to which individuals are judged is influenced by the sociodemographic factors of the observer as well as the stigmatized individual (Martin et al., 2007). Additionally, in some cases people judge those with mental illness as having strengths; for example, believing people with bipolar disorder to be particularly creative (Galvez et al., 2011; Kiume, 2017). …

A Systematic Analysis Of Eye-Tracking Metrics For Sleepiness, Debasis Roy

Masters Theses

”Sleepiness or sleep deprivation is a serious hazard that can be life-threatening in carrying out certain tasks (e.g., when driving or executing attention-critical tasks). Eye movement can provide cues on sleepiness. Hence, eye-tracking metrics have the potential to detect sleepiness.

In this research, we used a systematic analysis approach to identify eye-tracking metrics for sleepiness. We used several databases to identify independent experimental studies that have used eye-tracking metrics to assess sleepiness. We identified 25 studies that included 674 participants where the participants’ data were captured both in an alert state and in a sleep-deprived state. In the analysis, we …

A Meta-Analysis: Gamification In Education, Yalin Wang

Masters Theses

“Gamification has been used in a variety of contexts including education. In order to understand the effects of gamification in education, a meta-analysis was conducted. A bottom-up approach was used to analyze the effects of game design elements on learning outcomes found in the literature search. The result suggests that gamification can enhance student learning outcomes. Elements such as points, leaderboards, competitions, progress bars, feedback, and collaboration have medium to large effect sizes. Gamification also has larger effects on young children in elementary education than learners at other education levels. The study offers suggestions and guidelines for educators on the …

Beyond "Children Are Different": The Revolution In Juvenile Intake And Sentencing, Joshua Gupta-Kagan

Faculty Scholarship

For more than 120 years, juvenile justice law has not substantively defined the core questions in most delinquency cases — when should the state prosecute children rather than divert them from the court system (the intake decision), and what should the state do with children once they are convicted (the sentencing decision)? Instead, the law has granted certain legal actors wide discretion over these decisions, namely prosecutors at intake and judges at sentencing. This Article identifies and analyzes an essential reform trend changing that reality: legislation, enacted in at least eight states in the 2010s, to limit when children can …

Increment And Decrement Effects In Motion Induced Blindness, Sofia C. Lombardo

Honors Theses and Capstones

Motion induced blindness (MIB) refers to the perceptual disappearance of a stationary stimulus in the presence of a motion mask. The current study investigated the degree to which afterimages affect MIB inhibition when measured as a contrast detection threshold in a modified replication of White et al. (2020). Adult participants (N = 3) with normal or corrected-to-normal eyesight completed a series of target detection tasks while viewing a standard MIB stimulus with the motion mask removed that consisted of increment versus decrement inducer and target components. A univariate ANOVA data analysis procedure revealed a significant afterimage effect (Scheffé p < 0.0253) on contrast detection threshold was found for targets presented at an interstimulus interval of 500 ms. This effect was stronger for decrement targets compared to increment targets in the decrement inducer conditions. Based on a comparison with previous research in which the MIB effect was found to endure across interstimulus intervals up to 15500 ms, the current findings indicate that afterimages do not significantly influence contrast detection thresholds for MIB. Further research is necessary for determining the strength and duration of afterimage effects on contrast detection thresholds in MIB that may be caused by interaction with the motion mask.

Service-Learning To Develop Responsiveness Among Preservice Teachers, Elizabeth S. White

International Journal for the Scholarship of Teaching & Learning

The purpose of this study was to examine the benefits, challenges, and limitations of a service-learning project designed to promote responsiveness among PK-12 preservice teachers (N=41). The service-learning included working with children (5- to 12-year-olds) at before- and after-school programs, interviewing site staff, and developing lesson plans for the children at each site. Data sources for this study included students’ reflections and group lesson plans. Qualitative analysis showed that what constituted benefits for some students, such as connecting with children and learning classroom management, were reported as challenges for others. Additionally, students’ ideas about responsiveness in education were focused on …

College of Nursing Faculty Research and Publications

Polygyny is a common family structure in sub-Saharan African countries. Previous studies have documented that women in this family structure have favourable attitudes towards intimate partner violence (IPV). Nevertheless, there is limited recent research concerning this association in Ghana. This study sought to investigate the association between polygynous statuses and endorsement of IPV among Ghanaian reproductive-aged married and in-union women while controlling for covariates. The study used the nationally representative data from the 2017/2018 Ghana Multiple Indicator Cluster Survey. The sample comprised 7800 married/in-union women aged 15–49. Data analyses included tests of association and multivariable modelling using binary logistic …

Aging Out Of Place: Quality Of Life And Successful Aging Among Aging Refugee Immigrants In The Us, Jonix Atieno Owino

Human Development and Family Science

As individuals age, they experience physical, cognitive, and socioemotional changes that may impact their well-being. However, little is known about well-being among aging refugees. Thus, the present study explores factors associated with quality of life and perceptions of successful aging among refugees who are aged 50 years and above. This mixed methods dissertation included a quantitative and qualitative study. For the quantitative study, 108 refugee participants (from Bhutan, Burundi, and Somalia) living in the US were surveyed to assess quality of life. Hierarchical regression analyses showed that females, older individuals, individuals with lower education levels, and African refugees reported lower …

Does Mom Know Best? The Influence Of Baby-Led Weaning On Picky Eating And Sweetener Use, Savanna Elizabeth Jean Westrom Jellison

Human Development and Family Science

Baby-led weaning, the process of an infant feeding themselves at the introduction of solid foods as opposed to being spoon-fed by a caregiver, is an under-researched area of infant development. There is a significant gap in knowledge regarding how baby-led weaning influences aspects of this critical period of development including picky eating and parental use of sweeteners or additives. The purpose of this research was to better understand the influence that feeding method has on optimal infant development. The central hypotheses were (1) that infants who baby-led weaned would have greater food acceptance and be less likely to be labelled …

Herbicide Screening In Industrial Hemp (Cannabis Sativa L.) Production, Joseph Eric Mettler

Plant Sciences

Lack of labeled herbicides for industrial hemp (Cannabis sativa L.) production in the U.S. accentuates urgency to identify herbicides for weed control. Weed competition reduced seed yield by 25 to 32%. Pre- and post-emergence herbicide experiments were conducted to evaluate hemp tolerance to herbicides and support efforts for herbicide registrations. For post-emergence herbicides, hemp response to clopyralid (105 g ae ha-1) and bromoxynil (280 g ae ha-1) exhibited the lowest phytotoxicity, up to 38%, with no reduction of yield compared with the hand-weeded check. Pre-emergence herbicides were more viable options because pendimethalin (1120 g ai ha-1), trifluralin (840 g ai …

Pursuing Gender Equality Through The Courts: The Role Of South Africa’S Women Judges,, Penelope Andrews

Articles & Chapters

The appointment of female judges in South Africa is part of the transformative constitutional project. This chapter examines the question of gender equality, specifically the contribution of female judges to the transformation of the judiciary. It explores whether women judges have, in their judgments, conscripted and interpreted the constitution to highlight and guarantee its transformative potential and possibilities. I looked at the impacts of women judges on constitutional jurisprudence and how the influence of women judges has interacted with the broader transformation of the judicial and political system after apartheid. I conclude that the presence of women in the judiciary …
