An Integrated Model For Information Adoption & Trust In Mobile Social Commerce, Fulya Acikgoz, Abdelsalam Busalim, James Gaskin, Shahla Asadi

Faculty Publications

Despite the growing importance of mobile social commerce (ms-commerce), little research has been conducted on the effects of informational and social factors on users’ post-adoption behavior. We, therefore, build on the understanding of mobile social commerce in the UK market and how it affects users’ post-adoption behaviors. Our theoretical model leverages the information adoption model, social support theory, and social influence theory. Data was gathered from 377 ms-commerce users from the UK and analyzed via Partial Least Squares (PLS-SEM). The research findings show that both informational and social factors have a positive impact on information adoption in ms-commerce apps. Furthermore, …

The New Marshmallow: The Effects Of Screen Use On Children's Ability To Delay Gratification, Benjamin Richardson, P. Thomas Fife, Joseph Steed, Caroline Crane, James Gaskin

Faculty Publications

In a digital age where screens are as ubiquitous as crayons once were, the relationship between screen use and a child’s development necessitates examination. This study investigates the effect of screen use—both by children and their parents—on children’s ability to delay gratification, a key predictor of future success. Utilizing an experimental design modeled after the Stanford Marshmallow Experiment, we found that children’s screen use did not significantly affect their ability to delay gratification. However, parental screen use for entertainment purposes was negatively associated with children’s capacity to delay gratification. Additionally, screens proved to be a more potent temptation than traditional …

Did I Buy The Right Gadget? A Methodological Replication Study, Paul A. Weisgarber, Joseph S. Valacich, Jeffrey L. Jenkins Jan 2024

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 Jan 2024

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, …

How Photography Became Contemporary Art: Inside An Artistic Revolution From Pop To The Digital Age, James R. Swensen Jan 2024

How Photography Became Contemporary Art: Inside An Artistic Revolution From Pop To The Digital Age, James R. Swensen

Faculty Publications

One of the most important, yet neglected, periods in photography's young history took place in the United States during the 1960s. For years, photographers who explored the medium's creative aspects, such as Alfred Stieglitz and Edward Weston, struggled for recognition and success. That changed decades later when, at long last, the American public accepted photography as an art form. The "photo boom" gained momentum in the 197OS with the rise of successful MFA programs, an increase in financial support, and recognition from museums and commercial galleries (neither of which had paid much attention to the medium in the past) (p. …

The Impact Of Changing Disclosure Requirements, Competition, And Private Capital On Firm Exit Methods And Premiums, James C. Brau, Ninon K. Sutton, Qiancheng Zheng Jan 2024

The Impact Of Changing Disclosure Requirements, Competition, And Private Capital On Firm Exit Methods And Premiums, James C. Brau, Ninon K. Sutton, Qiancheng Zheng

Faculty Publications

Changing disclosure requirements and the evolution of US markets in the 21st century have created historic shifts in the exit strategies and payoffs for private firms. The propensity to sell to an acquirer has dominated firm exits in recent decades, especially for smaller private firms in highly concentrated industries. Exceptions to the merger exit preference are venture capital‐backed firms, which exhibit an enduring preference for IPOs, likely due to the reputation effects associated with this strategy. While the premium for IPO exits has exceeded that for M&A exits in the past, we document a reversal in this pricing trend: in …

Justice Theater In The Criminal Law Curriculum, Gregory Brazeal Jan 2024

Justice Theater In The Criminal Law Curriculum, Gregory Brazeal

Faculty Publications

For the last half-century, law students have been required to take a criminal law course that ostensibly trains them to think critically about the justifications for criminal punishment. The same students have then gone on to serve as central actors in a system of mass incarceration that millions of Americans today view as profoundly unjust. How did this happen? A number of legal scholars, notably including Alice Ristroph in her 2020 Article "The Curriculum of the Carceral State," have argued that the traditional criminal law curriculum has played a role in creating and reproducing the practices of mass incarceration. This …

No-Poach Agreements: An Overview Of Us, Eu, And National Case Law, Donald J. Polden

Faculty Publications

The United States, European Union, and many other international jurisdictions have antitrust and competition laws that seek to prevent anticompetitive conduct concerning labor and employment relationships. However, for many years these prohibitions on restraints of trade in labor markets and employment relationships were not routinely and rigorously enforced by those jurisdictions. The lack of governmental attention to these labor market practices has changed in important ways in recent years. Across many jurisdictions, we are now seeing more intense attention to conduct that suppresses wages of workers and their freedom of job mobility to other comparable positions. From an international perspective, …

Negotiating Quotidian Justice In The Science Classroom, Christopher Irwin, Joshua Ellis Jan 2024

Negotiating Quotidian Justice In The Science Classroom, Christopher Irwin, Joshua Ellis

Faculty Publications

In this conceptual paper, we explore how science teachers might enact social justice through their everyday science instruction. Drawing on empirical literature and our own K-12 teaching experience, we develop a heuristic for mapping classroom discourses to engage in action and reflection to change both the world of the classroom community, and the world beyond the school. We suggest how this heuristic can be used for justice-oriented science teaching independently of (or as a supplement to) any existing frameworks for science teaching to promote social justice. Our proposed model for social justice through disciplinary science teaching frames justice not as …

Aquatic ecosystems - lakes, ponds and streams - are hotspots of biodiversity in the cold and arid environment of Continental Antarctica. Environmental change is expected to increasingly alter Antarctic aquatic ecosystems and modify the physical characteristics and interactions within the habitats that they support. Here, we describe physical and biological features of the peripheral 'moat' of a closed-basin Antarctic lake. These moats mediate connectivity amongst streams, lake and soils. We highlight the cyclical moat transition from a frozen winter state to an active open-water summer system, through refreeze as winter returns. Summer melting begins at the lakebed, initially creating an …

Hydrologic reconstructions from North America are largely unknown for the Middle Miocene. Examination of fungal palynomorph assemblages coupled with traditional plant-based palynology permits delineation of local, as opposed to regional, climate signals and provides a baseline for study of ancient fungas. Here, the Fungi in a Warmer World project presents paleoecology and paleoclimatology of 351 fungal morphotypes from 3 sites in the United States: the Clarkia Konservat-Lagerstätte site (Idaho), the Alum Bluff site (Florida), and the Bouie River site (Mississippi). Of these, 83 fungi are identified as extant taxa and 41 are newly reported from the Miocene. Combining new plant-based …

Contribution Of Campaign Gnss Toward Parsing Subsidence Rates By Time And Depth In Coastal Bangladesh, Michael S. Steckler, Md Hasnat Jaman, Céline Jo Grall, Steven L. Goodbred, Carol A. Wilson, Bar Oryan

Faculty Publications

Coastal regions are vulnerable to rising seas, increasing storm magnitude, and decimation of ecologically-fragile areas. Deltas are particularly sensitive to the balance between sea-level rise, land subsidence and sedimentation that determine relative elevation. Bangladesh has been highlighted as being at risk from sea-level rise. Integrating measurements from different methods can approach a more complete understanding of factors controlling areally and temporally varying subsidence rates. To augment our compilation of rates from stratigraphic wells, historic buildings, vertical strainmeters, RSET-MH, and continuous Global Navigation Satellite System, we resurveyed 48 geodetic monuments in coastal Bangladesh ∼18 years after the monuments were installed.

Optimizing Privacy And Utility Tradeoffs For Group Interests Through Harmonization, Bishwas Mandal, George Amariucai, Shuangqing Wei Jan 2024

Optimizing Privacy And Utility Tradeoffs For Group Interests Through Harmonization, Bishwas Mandal, George Amariucai, Shuangqing Wei

Faculty Publications

We propose a novel problem formulation to address the privacy-utility tradeoff, specifically when dealing with two distinct user groups characterized by unique sets of private and utility attributes. Unlike previous studies that primarily focus on scenarios where all users share identical private and utility attributes and often rely on auxiliary datasets or manual annotations, we introduce a collaborative data-sharing mechanism between two user groups through a trusted third party. This third party uses adversarial privacy techniques with our proposed data-sharing mechanism to internally sanitize data for both groups and eliminates the need for manual annotation or auxiliary datasets. Our methodology …

Initial Exploration Of Zero-Shot Privacy Utility Tradeoffs In Tabular Data Using Gpt-4, Bishwas Mandal, George Amariucai, Shuangqing Wei Jan 2024

Initial Exploration Of Zero-Shot Privacy Utility Tradeoffs In Tabular Data Using Gpt-4, Bishwas Mandal, George Amariucai, Shuangqing Wei

Faculty Publications

We investigate the application of large language models (LLMs), specifically GPT-4, to scenarios involving the tradeoff between privacy and utility in tabular data. Our approach entails prompting GPT-4 by transforming tabular data points into textual format, followed by the inclusion of precise sanitization instructions in a zero-shot manner. The primary objective is to sanitize the tabular data in such a way that it hinders existing machine learning models from accurately inferring private features while allowing models to accurately infer utility-related attributes. We explore various sanitization instructions. Notably, we discover that this relatively simple approach yields performance comparable to more complex …

The Economics Of Privacy And Utility: Investment Strategies, Chandra Sharma, George Amariucai, Shuangqing Wei Jan 2024

The Economics Of Privacy And Utility: Investment Strategies, Chandra Sharma, George Amariucai, Shuangqing Wei

Faculty Publications

The inevitable leakage of privacy as a result of unrestrained disclosure of personal information has motivated extensive research on robust privacy-preserving mechanisms. However, existing research is mostly limited to solving the problem in a static setting with disregard for the privacy leakage over time. Unfortunately, this treatment of privacy is insufficient in practical settings where users continuously disclose their personal information over time resulting in an accumulated leakage of the users' sensitive information. In this paper, we consider privacy leakage over a finite time horizon and investigate optimal strategies to maximize the utility of the disclosed data while limiting the …

Subcooled Pool Boiling On Hierarchical Micro- And Nanostructure-Modified Copper Surfaces In Hfe-7100 Dielectric Liquid, Shayan Davani, Bin Zhang, Brendon Doran, Luke Hansen, Mohammad Khan, Mahdi Roodbari, Wen Jin Meng, Arden L. Moore

Faculty Publications

Hierarchical surfaces comprised both microscale and nanoscale structures have been previously studied as a means of targeting multiple length scales to achieve superior pool boiling performance. However, preceding studies have focused almost exclusively on high surface tension working fluids, while technologically important low surface tension fluids have remained largely unexplored. Due to their significantly lower surface tension these liquids tend to push out the air trapped in surface cavities of the heating surface, resulting in fewer nucleation sites compared to the same surface in water at low to moderate superheats. Thus, developing effective surface modification techniques for pool boiling in …
