An Examination Of The Stability Of The Remembering Self When Measuring Social Connection Derived From A Shared Leisure Experience, Camilla Hodge, Karen K. Melton, Mat D. Duerden, Mark A. Widmer, Aubrey Rushton, Alexis Kelley

Faculty Publications

Social connection has been identified as a public health priority, and is often positioned, in various forms, as an outcome of leisure experiences. In cases of assessing the hedonic quality of experiences, research has identified a relative permanence and stability in the remembering self; however, whether the same is true when measuring social connection is unknown. Therefore, this study aimed to determine whether recall of social connection after a structured, shared leisure experience changed over time. We compared assessments of social connection among a sample of 68 adults immediately following four structured, shared leisure experiences and again four weeks later. …

The Surrogate Fold Catalog: A Design Tool For Origami-Inspired Mechanical Systems, Larry L. Howell, Ivy Running, Phebe Ramsdell, Carolina Wright, Spencer P. Magleby

Faculty Publications

Origami has inspired work in many fields of science and engineering. However, it can be difficult to transfer the motion of an origami design from folded paper to thicker, stiffer materials. When using engineering materials, creases from an origami fold pattern are usually replaced with “surrogate folds”. While many different surrogate folds have been developed, it is challenging for a designer to quickly survey and compare potential surrogate folds. Surrogate folds can improve many origami-inspired designs and applications by changing how the designs are manufactured and how they behave. This work categorizes compliant mechanisms that may be effective as surrogate …

Characterization Of Magnetically Stabilized Hinges For Origami-Inspired Mechanisms, Larry L. Howell, H T. Pruett, Philip Klocke, Spencer Magleby

Faculty Publications

Origami-inspired mechanisms provide opportunities for deployable systems, including reflectarray antennas. There is a need for approaches to deploy and stabilize such arrays. Magnetic mechanisms show promise for meeting those needs and methods for modeling their behavior would facilitate their design and analysis. We demonstrate the existence of bistability in select configurations of magnetically stabilized hinges and characterize their equilibrium positions as a function of parameters estimated from simulation data for these mechanisms. Other relevant information such as potential energy, axial force data, angular position of unstable equilibria, and transition values from bistability to monostability are also modeled. The results are …

Methodology For Designing And Improving Novel Kirigami Patterns Using The Hamiltonian Circuit Framework, Larry L. Howell, Nathan Coleman, Mckaelin Edralin, Specer P. Magleby, Denise Halverson, Zhong You

Faculty Publications

The ability to compactly fold arrays to be deployed in space has seen an increasing demand in the aerospace industry. In this work, we build on existing methods to create kirigami patterns which can stow compactly and deploy out to a predictable shape using Hamiltonian circuits. We detail how designers can use this method to create novel kirigami patterns for a desired deployed shape and area. We also discuss techniques for modifying and improving the behavior and performance of kirigami patterns created using this method, and then show example applications including as a deployable radio frequency antenna of this method …

Religion And Lgbtq Suicidality: A Systematic Review, Michael A. Goodman

Faculty Publications

Studies have consistently shown that LGBTQ individuals are at increased risk for several mental and physical health challenges including suicidality. The relationship between religion and LGBTQ wellbeing in general and LGBTQ suicidality in specific has increasingly been the subject of scholarly investigation. This systematic review examines all peer-reviewed articles included in the EBSCO PsychInfo database since 2000 (49 studies in all). These studies reveal a complex relationship which is both nuanced and at times contradictory. The majority of studies (65%) found at least one religiosity related predictor to be a risk factor for LGBTQ suicidality, 53% found at least one …

Torture And Trolleys: Accepting The Nearly Absolute Wrongness Of Philanthropic Torture Of A Perpetrator, David Jensen

Faculty Publications

One potentially morally justified use of torture is found in philanthropic torture of a perpetrator (PTP): scenarios in which a perpetrator has instigated significant pending suffering against innocents and in which the suffering can be prevented by means of the perpetrator’s cooperation. These situations involve a clash of two intuitions: that torture is in some strong and obvious sense absolutely morally wrong, and that torture or harm of an immoral perpetrator may be permissible to prevent equally abhorrent, if not greater, moral wrongs. My view is that a dually grounded view—permissible on theoretical grounds but wrong on practical grounds—can do …

Did I Buy The Right Gadget? A Methodological Replication Study, Paul A. Weisgarber, Joseph S. Valacich, Jeffrey L. Jenkins

Faculty Publications

This study is a methodological replication of Valacich et al.’s (2018) experiment, which investigated the evaluability hypothesis in the context of technology product assessment. The evaluability hypothesis suggests that the evaluation context significantly influences how users assess and perceive technology features. More specifically, it posits that the perception of technology features, as well as the ultimate selection of a technology product, is likely to differ depending on whether a single technology is evaluated in isolation or multiple technologies are evaluated simultaneously. Our replication study consisted of 310 participants who evaluated two wireless internet products with two product features – connection …

Technological Health: A New Perspective On Individual Well-Being In The Digital Era, Tanner Skousen, J. Andrew Lear

Faculty Publications

An individual’s well-being encompasses various facets, including physical, mental, and social health. This paper proposes that in a technology-dependent world, practitioners and researchers must adopt a “technological health” perspective. Through conceptual inquiry and extensive literature review, we propose the concept of technological health, drawing from related concepts. We present an initial framework that explicates technological health through the dimensions of access to technology, ability to use technology, and autonomy over technology. Practically, this new perspective refocuses our understanding of technological challenges and invites an ideology of diagnoses and treatments to comprehensively address individual-level concerns associated with personal technology use. Academically, …

Does Leaving Faith Mean Leaving Family? Longitudinal Associations Between Religious Identification And Parent-Child Relationships Across Adolescence And Emerging Adulthood, Justin J. Hendricks, Sam A. Hardy, Emily M. Taylor, David C. Dollahite

Faculty Publications

The present study investigated the parent-child relational repercussions of converting to religion, switching, or de-converting from religion. Qualitative research indicates that these religious changes may negatively affect parent-child relationship quality, however, few quantitative studies investigate this issue. Subsequently, we utilized structural equation modeling to test if changes in religious identification during adolescence and emerging adulthood predicted worse parent-child relationship quality using three waves of the National Study of Youth and Religion (N = 2,352). We found that deconversion between Waves 1–2 significantly predicted poorer parent-child relationship quality at Wave 2 and father-child relationship quality at Wave 3. Further, deconversion between …

Language Change At The Intersections Of Movement, Economy, And Orientation, Joseph A. Stanley, Margaret E. L. Renwick, Monica Nesbitt

Faculty Publications

A growing amount of research on North American English varieties shows that many sociolinguistic variables peaked among the Baby Boomer Generation (born approximately 1946–64). By “peak,” we mean that a linguistic phenomenon in one community has reached its point of greatest intensity and is maximally divergent from realizations of that same variable in most other North American communities. Similarly, we also find studies that describe a “cliff” beginning among Generation X (born approximately 1965–82) such that after generations of relative stability, local dialect features are lost. Nesbitt (2021, 359) observes that “the Baby Boomer–Gen X transition appears to be a …

Movement, Economy, Orientation 20th Century Shifts In North American Language, Monica Nesbitt, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

How are regional varieties of English faring in the US?

Ample evidence shows that canonical regional variables are undergoing _____

• “reversal” in Cincinnati and Philadelphia (Strassel & Boberg 1996, Fruehwald 2017)

• “decline” and “fall” in Michigan (Rankinen et al. 2019, Nesbitt 2021)

• “rejection” and “retreat” in Raleigh (Dodsworth & Kohn 2012; Dodsworth & Benton 2017)

Nesbitt (2021: 359) observes that “[T]he Baby Boomer–Gen X transition appears to be a pivotal transition throughout the country [and] appears to be of great importance to North American dialects in general.”

Putting Students In Their Place. The Role Of Placement Testing In Language Programs, Troy L. Cox, Matthew P. Wilcox

Faculty Publications

A perennial issue that nearly all language programs face with the arrival of new students is: where is the best place for each student to begin their course of study within our curricular structure given their current language abilities? When students have no previous language learning experience, the decision seems easy: place them in the beginning- level class. But when students have prior experience, deciding where they belong becomes more complicated given the wide range in the quality and quantity of previous exposure and the level of ability attained. Programmatic exigencies and resources may constrain student placement even further.

Dobbs, Abortion Laws, And In Vitro Fertilization, Kerry L. Macintosh

Faculty Publications

Health Organization1 has upended abortion jurisprudence. The case concerned a Mississippi law barring most abortions when the probable gestational age of the fetus was greater than fifteen weeks.2 Holding that the U.S. Constitution did not protect a right to abortion through the Due Process Clause of the Fourteenth Amendment,3 the Court overruled Roe v. Wade4 and Planned Parenthood of Southeastern Pennsylvania v. Casey.

5 Abortion, it explained, differed from other protected acts because abortion destroyed potential life.6 Deeming rational basis review appropriate,7 the Court concluded that the Mississippi law was rationally related to what the Court accepted as legitimate state …

Cancer Survivorship And Subjective Cognitive Decline In The Us: Results From A Nationally Representative Sample, Monique J. Brown, Ally Hucek, Jingkai Wei, Loretta Anderson, Muzi Na

Faculty Publications

Cancer may be associated with objective cognitive decline. However, studies examining the link between cancer and subjective cognitive decline (SCD), which occurs earlier during cognitive trajectories, are lacking. In addition, research assessing risk factors for SCD among cancer survivors is scant. Therefore, this study aimed to examine the association between cancer and SCD in the past year, and assess the association between age of diagnosis, cancer treatment, and SCD among cancer survivors. Data were obtained from the 2021 Behavioral Risk Factor Surveillance System (N=15,447). Crude and adjusted logistic regression models, controlling for sociodemographic characteristics, were used to determine the association …

Shock-Wave Tolerant Phase Reconstruction Algorithm For Shack–Hartmann Wavefront Sensor Data, Thomas E. Defoor, Matthew Kalensky, Matthew R. Kemnetz, Timothy J. Bukowski, Mark F. Spencer

Faculty Publications

We develop a phase reconstruction algorithm for the Shack–Hartmann wavefront sensor (SHWFS) that is tolerant to phase discontinuities, such as the ones imposed by shock waves. In practice, this algorithm identifies SHWFS locations where the resultant tilt information is affected by the shock and improves the tilt information in these locations using the local SHWFS observation-plane irradiance patterns. The algorithm was shown to work well over the range of conditions tested with both simulated and experimental data. In turn, the reconstruction algorithm will enable robust wavefront sensing in transonic, supersonic, and hypersonic environments.

The Influence Of Body Mass Index On Ready-To-Wear Clothing Preferences Of Young African-American Female Consumers, Jung-Im Seo, Vadel Shivers

Faculty Publications

Although consumers’ body shapes are various, the sizes of bust, waist, and hips of ready-to-wear (RTW) are fairly standardized in the apparel manufactures’ sizing charts, leading to clothing fit issues for many consumers. Body Mass Index (BMI) is an important factor that has an impact on body image perception, but there is little research on the influence of the obesity prevalence on RTW clothing preferences. The purposes of this study are to examine the correlation between African-American women’s obesity prevalence represented by BMI and RTW clothing preferences such as store preference and clothing benefit sought as well as clothing fitting …

A 30-Year Dataset Of Co2 In Flowing Freshwaters In The United States, Timothy R. Toavs, Caleb T. Hasler, Cory D. Suski, Stephen R. Midway

Faculty Publications

Increasing atmospheric carbon dioxide (CO2) concentrations have been linked to effects in a wide range of ecosystems and organisms, with negative effects of elevated CO2 documented for marine organisms. Less is known about the dynamics of CO2 in freshwaters, but the potential exists for freshwater organisms to be challenged by elevated CO2. In flowing freshwaters CO2 exhibits more variability than in lakes or the ocean, yet spatiotemporally extensive direct measures of CO2 in freshwater are rare. However, CO2 can be estimated from pH, temperature, and alkalinity—commonly collected water quality metrics. We used data from the National Water Quality Monitoring Council …

Atmospheric Flash Drought In The Caribbean, Craig A. Ramseyer, Paul W. Miller

Faculty Publications

Despite the intensifying interest in flash drought both within the United States and globally, moist tropical landscapes have largely escaped the attention of the flash drought community. Because these ecozones are acclimatized to receiving regular, near-daily precipitation, they are especially vulnerable to rapid-drying events. This is particularly true within the Caribbean Sea basin where numerous small islands lack the surface and groundwater resources to cope with swiftly developing drought conditions. This study fills the tropical flash drought gap by examining the pervasiveness of flash drought across the pan-Caribbean region using a recently proposed criterion based on the evaporative demand drought …
