All Grantees Publications

Monitoring the farm acoustic environment can provide important information about processes affecting crop production. This paper assesses farmers’ knowledge and attitudes toward acoustic technology for farm monitoring in Rwanda. Stratified random sampling was used to select 430 farmers from 3 sectors. Demographic, farm, and technical knowledge data were collected from farmers with a survey. Cross-tabulation results show farmers with secondary and university education are more interested in acoustic technology than those with a primary education and farmers engaged in commercial farming are more interested in technology for monitoring acoustic sources than subsistence farmers. However, nearly all farmers are willing to …

Crop damage attributed to pest birds is an important problem, particularly in low-income countries. This paper describes a prototype system for pest bird detection using a Conv1D neural network model followed by scaring actions to reduce the presence of pest birds on farms. Acoustic recorders were deployed on farms for data collection, supplemented by acoustic libraries. The sounds of pest bird species were identified and labeled. The labeled data were used in Edge Impulse to train a tinyML Conv1D model to detect birds of interest. The model was deployed on Arduino Nano 33 BLE Sense (nodes) and XIAO (Base station) …

Regulation By (Bad) Proxy: How Selective Application Of Transaction Cost Economics Tainted The Ftc's Proposed Ban Of Employee Noncompete Agreements, Alan J. Meese

Faculty Publications

Agencies have imperfect information about conduct they regulate. This problem is particularly acute when identical conduct has differing effects in various markets. Determining the economy-wide impact of such conduct can be difficult or impossible.

The FTC faces such a challenge. The Commission has announced a rule banning the nation’s 30 million employee noncompete agreements (“NCAs”) as unfair methods of competition under Section 5 of the FTC Act. The Commission determined that NCAs likely reduce aggregate wages, helping to establish a presumptive violation. The Commission also found that nearly all NCAs are both procedurally coercive—because employers use overwhelming bargaining power to …

Space ‘Tourism’: A Framework For Ensuring ‘Safe And Orderly Development’ Lessons Learnt From The U.S. And Aviation, Sarah J. Fox

Journal of Air Law and Commerce

In August 2023, following its successful mission, Virgin Galactic announced the intention to provide scheduled services into space. Yet, this paper sets out to present evidence to argue that, from an international (U.N.) perspective, there has been a lack of activity to establish safeguards and to ensure a fit for purpose governance and oversight mechanism is in place for this new and growing sector—space tourism. The research is undertaken by way of a comparison law/policy analysis which factors in key historic events across both aviation and space. The main focus is given to the developments and approach of …

Non-Fungible Tokens (Nfts) And Copyright Law, Ochoa, Tyler T.

Santa Clara High Technology Law Journal

The concept of using non-fungible tokens (NFTs) to facilitate and authenticate sales of digital art dates back to 2014; but it took several years before the concept really captured public attention. Since copyright law governs the reproduction of works of art, including digital images, the connection to NFTs seems obvious. Yet, copyright law is only tangentially related to NFTs, for two reasons. First, buying an NFT does not, by itself, convey any rights to reproduce or display the work associated with that token. Instead, those rights are governed entirely by the contract that accompanies the sale. Second, minting and selling …

In Event Of An (Ai) Emergency: Interpreting Continuity Of Government Provisions In State Constitutions, Frazier, Kevin T.

Santa Clara High Technology Law Journal

“Of this I am certain: If we prepare ourselves so that a terrible attack—although it might hurt us—could not destroy us, then such an attack will never come.” - Edward Teller, the “Father of the Hydrogen Bomb,” in an interview with Allen Brown of This Week Magazine in 1957.

Bad actors have already used or may soon use AI to disrupt critical infrastructure, influence elections, and upend economies. Those most concerned about the risks posed by AI argue that it is a matter of when and not if state governments will have to respond to threatened or realized acts of …

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 …

Alterity As A Mirror Of Identity: Primo Levi’S Self Representation In Other People’S Trades, Ilona Klein

Faculty Publications

Primo Levi reveals much about himself in the fifty-one short essays of L’altrui mestiere (Other People’s Trades). This study analyzes L’altrui mestiere as the awareness of the “self” through the observation of “otherness” — other people, but also other living beings which are not human (mammalian animals and insects), others as minerals, and others as hypotheses, theories, writings, microcosmic or macrocosmic conceptions that Levi uses to weave a discourse of “alterity” as a mirror of “identity.” L’altrui mestiere’s narrative pattern revolves around contrasts and comparisons between the familiar and the unfamiliar, the canny and the uncanny, the …

Sociology Faculty Publications and Presentations

Latine immigrant households often face housing instability due to language barriers, immigration status, and limited access to government resources. Oregon farmworkers experience additional obstacles to safe and stable housing caused by low wages, a lack of affordable housing options, and social isolation. In light of the identified needs and lack of equitable access to resources that this group experiences, the Evicted in Oregon research team conducted focus groups with Latine immigrant and farmworker tenants in Multnomah, Washington, and Marion Counties. The aim was to gain insight into their experiences with eviction and understand how they navigated through evictions during the …

The Next Generation, Jeremiah Chin

Articles

What would the law look like if we let children remake it? Laws govern, classify, and circumscribe children who inherit the law and its consequences. Discourses of power invoke children as rhetorical strategies to gain political favor or obviate a position—yet children are uncritically excluded from participating in the systems that control them. Children are subjected to the laws and objects of legislation, but denied the rights, autonomy, or authority to participate in the making of law and policy. Even the conceptualization of the constitutional rights of children is treated as an assumption, ill-defined and under theorized by traditional legal …

America's Next "Stop Model!": Model Deletion, Jevan Hutson, Ben Winters

Detecting Social Desirability Bias With Human-Computer Interaction: A Mouse-Tracking Study, Paul A. Weisgarber, Joseph S. Valacich, Jeffrey L. Jenkins, David Kim, Manasvi Kumar

Faculty Publications

Social desirability bias undermines self-report accuracy, necessitating novel approaches to detect and mitigate its impact. This study aimed to investigate the influence of social desirability on questionnaire responses by analyzing mouse cursor movements and answering behaviors. Respondents (n=238) completed a health and wellness questionnaire while their mouse cursor data was recorded. The results revealed that individuals under a higher social desirability treatment exhibited significantly longer response times and slower mouse cursor speeds, supporting the hypothesis that they may engage in more cautious and deliberate responding. However, no significant differences were found in terms of mouse cursor deviations or answer switches …

Adverse drug reactions (ADR) are important information for verifying the view of the patient on a particular drug. Regular user comments and reviews have been considered during the data collection process to extract ADR mentions, when the user reported a side effect after taking a specific medication. In the literature, most researchers focused on machine learning techniques to detect ADR. These methods train the classification model using annotated medical review data. Yet, there are still many challenging issues that face ADR extraction, especially the accuracy of detection. The main aim of this study is to propose LSA with ANN classifiers …

Technoference In Parenting And Impacts On Parent–Child Relationships And Child Development, Brandon T. Mcdaniel Phd, Lisa Linder, Mariek M.P. Vanden Abeele, Alison K. Ventura, Sarah M. Coyne, Rachel Barr

Health Services and Informatics Research

“Technoference” is a term that describes how parent media use (e.g., phone use) can interfere with parent–child relationships and interactions. Research has shown technoference effects on parents and children ranging in age from infancy to adolescence, such as decreased parent responsiveness and adverse child behavioral outcomes. However, potential benefits of parent media use have also been identified, such as media use to cope with stress, stay connected, increase breastfeeding perseverance, and seek parenting information. Technoference has only been researched for about a decade, and there are large research gaps. We propose a research agenda to parse out long-term or cumulative …

Heavy Users, Mobile Gamers, And Social Networkers: Patterns Of Objective Smartphone Use In Parents Of Infants And Associations With Parent Depression, Sleep, Parenting, And Problematic Phone Use., Brandon T. Mcdaniel Phd, Jenny Radesky, Jessica Pater, Adam M Galovan, Annalise Harrison, Victor P. Cornet Ms, Lauren Reining, Alexandria Schaller, Michelle Drouin

Health Services and Informatics Research

Smartphone use during parenting is common, which may lead to distraction (also known as technoference). However, it is likely that some phone activities are less disruptive to parents and children. In this study, we explored smartphone use (via passive sensing across 8 days) within 264 parents of infants, measuring parents' application use on their phone (e.g., messaging, social media, mobile gaming, video chat) and phone use across contexts (e.g., during feeding and at bedtime). We utilized latent profile analysis to identify profiles of users, revealing five user types:

Attachment Security And Problematic Media Use In Infancy: A Longitudinal Study In The United States., Jane Shawcroft, Sarah M Coyne, Lisa Linder, Brandon N Clifford, Brandon T. Mcdaniel Phd

Health Services and Informatics Research

Media use during childhood has quickly become a norm across the United States and in other countries. One area still not well understood is the development of problematic (or maladaptive and disruptive) media use in children. This research examines the role of attachment security as a central component in the development of problematic media use over time in a sample of 248 parent-child dyads (9.50% African American, 20.66% Hispanic, 62.81% White, 2.07% Asian, 4.96% other ethnicities). We examined the relationship between attachment security and problematic media use one and 2 years later. We then constructed a mediation model examining parent …

Shipping is the backbone of international trade. With a contribution of more than 80 per cent of cargo by volume and 70 per cent by value, it is the most efficient mode of transportation. The vital cargo it transports includes medical supplies and equipment, as well as food, energy, raw materials, and manufactured goods. At the same time, shipping contributes to approximately 3 per cent of the world’s greenhouse gas emissions, a figure that is expected to rise if no action is taken to reduce emissions. The 2023 International Maritime Organization Strategy on Reduction of Greenhouse Gas Emissions sets out …

One-Pot Microwave-Assisted Approach Of Polydiacetylene/Zinc Oxide Nanocomposite For Reversible Thermochromic, Chanita Khanantong, Thanutpon Srinopkun, Thitirut Boonmak, Jintana Siriboon

Journal of Metals, Materials and Minerals

This study introduces a new technique to fabricate the reversible poly(PCDA/ZnO) nanocomposites thermochromism. Our preparation process is the solution-mixing method, which is supported by microwave synthesis time instead of ultrasonic bath or stirrer. The presence of ethanol molecules in aqueous media in the solution-mixing method induces dipolar polarization. In addition, the presence of Zn2+ leaking out of the ZnO can produce ionic polarization. These factors affect the shape of poly(PCDA/ZnO) nanocomposites based on their thermochromic properties. The optical properties of poly(PCDA/ZnO) nanocomposite were determined through UV-Vis absorption spectroscopy. The morphology of this nanocomposite was examined by scanning electron microscopy, and …
