Automated Detection Of Vaping-Related Tweets On Twitter During The 2019 Evali Outbreak Using Machine Learning Classification, Yang Ren, Dezhi Wu, Avineet Singh, Erin Kasson, Ming Huang, Patricia Cavazos-Rehg

Publications

There are increasingly strict regulations surrounding the purchase and use of combustible tobacco products (i.e., cigarettes); simultaneously, the use of other tobacco products, including e-cigarettes (i.e., vaping products), has dramatically increased. However, public attitudes toward vaping vary widely, and the health effects of vaping are still largely unknown. As a popular social media, Twitter contains rich information shared by users about their behaviors and experiences, including opinions on vaping. It is very challenging to identify vaping-related tweets to source useful information manually. In the current study, we proposed to develop a detection model to accurately identify vaping-related tweets using machine …

How Does Passive Remote Monitoring Technology Affect Perceived Outcomes For Older Adults, Their Family And Friend Caregivers, And The Healthcare System?, Lori E. Weeks, Grace Warner, Sue Nesto, Heather Rushton, Kathleen Ledoux, Bradley Hiebert, Lorie Donelle Phd, Rn, Fcan

Publications

Background: Most people who receive home care services also rely extensively on support provided by family and friend caregivers. The utilization of technology such as help from remote monitoring technologies (RMT) that send notifications from sensors (e.g., motion sensors, cameras, medication administration monitoring) to a recipient (e.g., family or friend caregiver, healthcare professional) can help to support care provision. Passive RMT uses sensors that do not require any action by the individual for the system to work. Objective: This study is a qualitative component of a pragmatic randomized controlled trial. Our objective is to report qualitative findings from the perspective …

Earnings Virality*, Brett Campbell, Michael S. Drake, Jacob Thornock, Brady Twedt

Faculty Publications

We examine the determinants and market consequences associated with earnings announcements going viral on social media, a phenomenon we label “earnings virality.” Using a comprehensive panel of historical Twitter data, we find that the typical earnings announcement receives relatively little social media coverage, but others go viral on social media, quickly reaching the feeds of millions of people. We find that viral earnings announcements generally have Twitter content that is more extreme in tone and contains less unique content. Further, earnings virality is positively associated with revenue surprises, investor recognition, retail investor ownership, and retail investor trading around the announcement. …

The Relevance Of Non-Income Tax Relief*, Michael S. Drake, Ryan V. Hess, Jaron H. Wilde, Braden M. Williams

Faculty Publications

Governments regularly offer non-income tax relief to attract business investment. However, it is unclear whether or how markets impound information about the relief into security prices. We use novel data from retrospective public records to examine the information content of non-income tax relief. We predict and find that the receipt and magnitude of this relief are both strongly associated with recipients’ future accounting performance and future abnormal returns. We further find that abnormal returns associated with the relief cluster around future earnings information events. In combination, this evidence suggests that non-income tax relief is value-relevant but is incorporated into prices …

Brokerage House Ipos And Analyst Forecast Quality, Mark Bradshaw, Michael S. Drake, Joseph Pacelli, Brady Twedt

Faculty Publications

We examine how brokerage firm IPOs influence the research quality of sell-side analysts employed by the brokerage. Our main results focus on earnings forecast bias and absolute forecast errors as proxies for research quality. Using a staggered difference-in-differences analysis, we document significant decreases in forecast bias and absolute forecast error during the two-year period centered on the analysts’ brokerage house IPO. In additional analyses, we explore several potential explanations for the short-term benefits of brokerage house IPOs. We find some evidence that IPOs delay the departure of more talented analysts and that the effects are more concentrated among analysts and …

Racial/Ethnic Disparities And Determinants Of Sufficient Physical Activity Levels, Vijay Nambi, Stephanie Koh, Jaideep Patel, Anum Saeed, Ahmed Ibrahim Ahmed, Mouaz Al-Mallah, Anandita Agarwala, Salim S Virani, Mahmoud Al Rifai

Faculty, Staff and Students Publications

INTRODUCTION: Adequate physical activity is an integral requirement for achieving cardiovascular health. Physical inactivity is the fourth leading cause of death worldwide. Hence, it is important to identify racial/ethnic groups that are less likely to achieve sufficient physical activity levels, and to address barriers to meeting physical activity requirements.

METHODS: Cross-sectional data from the 2006-2015 National Health Interview Survey (NHIS) were used to compare self-reported sufficient physical activity among different racial/ethnic groups: non-Hispanic (NH) Whites, NH Blacks, NH Asians, and Hispanics in the United States. Sufficient physical activity was defined as ≥ 150 minutes per week of moderate-intensity physical activity, …

Law’S Contributions To The Mindfulness Revolution, Elizabeth F. Emens

Faculty Scholarship

These are phenomenally challenging times. Mindfulness is a tool that can help lawyers support themselves, each other, their clients, and their collaborators in the hard work needed to build community and take action. For these and other reasons, mindfulness has made major inroads into law and legal institutions. Law firms, law schools, and courthouses offer training in mindfulness meditation to support the cognitive clarity and emotional self-regulation necessary for the demanding work of analyzing problems, resolving conflicts, overcoming bias, and doing justice. A growing literature, from empirical social science to legal scholarship, catalogs these and other benefits of mindfulness for …

Management Of A Novel Autoimmune Disease, Copa Syndrome, In Pregnancy, Mary C Tolcher

Faculty, Staff and Students Publications

BACKGROUND: COPA syndrome is a rare autoimmune disease, demonstrating an autosomal dominant inheritance pattern with variable penetration that occurs more frequently in females than males. This disease manifests in childhood as pulmonary hemorrhage, arthritis, and renal disease.

CASE: We present a case of obstetric management of a 20-year-old nulligravida patient with a diagnosis of COPA syndrome. Her case was further complicated by multiple antepartum admissions for hypoxemia and a complex psychosocial history of substance use. On her first antepartum admission, rheumatology recommended management with hydroxychloroquine, inhaled corticosteroids (budesonide), and bronchodilators (albuterol inhaler) as needed. On admission for induction of labor, …

Macroarchaeology, Epistomology, And The Quality Of The Archaeological Record, James R. Allison

Faculty Publications

Perrault (2019) combines a critique of current archaeological practice with a call to re-center research on questions of culture history as well as “macroarchaeology”, or the search for large-scale patterns of human behavior and cultural development. His arguments for what archaeologists should do (and stop doing) are driven by the way the quality of the archaeological record underdetermines the answers to questions that archaeologists often seek to answer. There is much to like in Perrault’s arguments, but there also are some problematic aspects. I agree that something like Perrault’s macroarchaeology should receive greater focus within the discipline, and that archaeologists …

Final Thoughts And Observations, James R. Allison, Heidi Roberts, Jerry D. Spangler

Faculty Publications

This chapter addresses three topics inspired by the discoveries made during Jackson Flat’s archaeological investigations. The first topic examines the implications of the discovery of early maize agriculture in the Far Western region. Our data suggest that the Far Western Basketmaker tradition developed on a trajectory separate from the Western Basketmaker groups associated with the White Dog Phase in the Four Corners region.

No Runs, Few Hits And Many Errors: Street Stops, Bias And Proactive Policing, Jeffrey A. Fagan

Faculty Scholarship

Equilibrium models of racial discrimination in law enforcement encounters suggest that in the absence of racial discrimination, the proportion of searches yielding evidence of illegal activity (the hit rate) will be equal across races. Searches that disproportionately target one racial group, resulting in a relatively low hit rate, are inefficient and suggest bias. An unbiased officer who is seeking to maximize her hit rate would reduce the number of unproductive stops toward a group with the lower hit rate. An unbiased policing regime would generate no differences in hit rates between groups.

We use this framework to test for racial …

The Genius Of Common-Law Intellectual Property, Shyamkrishna Balganesh

Faculty Scholarship

Among Richard Epstein’s influential contributions to legal scholarship over the years is his writing on common-law intellectual property. In it, we see his attempt to meld the innate logic of the common law’s conceptual structure with the realities of the modern information economy. Common-law intellectual property refers to different judge-made causes of action that create forms of exclusive rights and privileges in intangibles, interferences that are then rendered enforceable through private liability. In this essay, I examine Epstein’s writing on two such doctrines, hot-news misappropriation and cybertrespass, which embrace several important ideas to which modern discussions of intellectual property would …

The Evolution Of Frederick Douglass’ Slavery Debate: An Examination Of His Rhetoric, Jacquelyn Torres

Political Science & International Studies | Senior Theses

From leading the Abolitionist movement to holding a lecture tour abroad, Frederick Douglass is well known for championing racial justice and leaving a legacy of exposing the evils of slavery. Scholars have primarily focused on Douglass’ actions as an abolitionist but not on the evolution of his thinking about slavery. While Douglass’ actions, such as in the Abolitionist movement, are discussed in-depth amongst academic circles, there is oversight regarding looking at his arguments about slavery. Douglass’ rhetoric was impacted by his experiences traveling abroad when he gave lectures in the British Isles between 1845-1847. This thesis examines speeches given by …

Status Anxiety And Overall Life Satisfaction Of Young Adults In The Bay Area, Samuel Casco

Global Public Health | Senior Theses

The published literature suggests social comparisons have significant negative effects on an individual’s psychological well-being. However, there is little to no research to suggest that an individual’s attainment of societal success has a relationship with one’s perceived life satisfaction.

A mixed-methods study involved young adults ages 18-29 in the Bay Area and were selected via a student researcher in the Global Public Health department of Dominican University of California. 115 participants completed surveys regarding self-perceived life satisfaction and status anxiety through the Qualtrics Survey Collection Tool. A Pearson’s Chi-Squared Test was conducted to find an association between life satisfaction and …

Real-Time Machine Learning Models To Detect Cyber And Physical Anomalies In Power Systems, Zakaria El Mrabet

Theses and Dissertations

A Smart Grid is a cyber-physical system (CPS) that tightly integrates computation and networking with physical processes to provide reliable two-way communication between electricity companies and customers. However, the grid availability and integrity are constantly threatened by both physical faults and cyber-attacks which may have a detrimental socio-economic impact. The frequency of the faults and attacks is increasing every year due to the extreme weather events and strong reliance on the open internet architecture that is vulnerable to cyber-attacks. In May 2021, for instance, Colonial Pipeline, one of the largest pipeline operators in the U.S., transports refined gasoline and jet …

Interrogating Whiteness In Graduate Education Culture: A Phenomenological Exploration Of Southeast Asian American Graduate Student Experiences, Lesley Nina Sisaket

Electronic Theses and Dissertations

The purpose of this transcendental phenomenological study is to understand the role that whiteness has in shaping the graduate education experiences of Southeast Asian American students in the United States. This study explores two research questions. 1) How do Southeast Asian American graduate students describe their graduate education? 2) How do Southeast Asian American graduate students describe concepts of whiteness, if any, throughout their graduate education? According to the experiences from six selfidentifying Southeast Asian American students, their graduate education experiences were described to be racially taxing, unchallenging, and isolating experiences. These findings stemmed from their graduate education experiences, which …

The Synthesis And Characterization Of Pb(Ii) Cyanoximates, Patricia Mcdaniel

Graduate Theses/Dissertations

A new series of Pb(II) cyanoximates were synthesized and characterized by elemental analysis (C, H, N, S), IR spectroscopy, thermal analysis, and X-ray crystallography. The goal was to synthesize compounds with a PbL₂ (L= selected known chelating cyanoximes) composition for use as potential new non-linear optical (NLO) materials, specifically second harmonic generators (SHG), which must belong to non-centrosymmetric space groups. A desktop procedure using Pb²⁺ is chosen due to its typically active 6s² lone pair of electrons, which are known to distort central polyhedra. A 1:2 ratio of Pb(II) to ligand were used to synthesize bulk products …

Modulation Of Electrocochleography Responses By Contralateral Broadband Noise In Young Adults, Riley J. Rickman

Graduate Theses/Dissertations

While it is known the auditory efferent system contains two distinct subgroups – the medial olivocochlear nucleus (MOC) and the lateral olivocochlear nucleus (LOC) – not much is known regarding the function of the LOC in humans. This study aims to evaluate the effect of activating the lateral olivocochlear (LOC) neurons via contralateral broad band noise (CBBN) on electrocochleography responses. A ten-minute time-blocked paradigm was utilized to evaluate both the slow and fast effect of the LOC neurons. Recordings were obtained at four points within this ten-minute block both with and without the presence of 50 dB SPL CBBN to …

Effect Of Electrocochleography Stimulus Rate And Intensity On Identification Of Noise Induced Hidden Hearing Loss In Humans, Amanda E. Mccarthy

Graduate Theses/Dissertations

Noise exposure has been known to cause both temporary and permanent shifts in hearing thresholds in humans. Animal and human studies have shown noise exposure to lead to damage to the ribbon synapses of the cochlea. This damage, referred to as noise induced hidden hearing loss (NIHHL), is not detectable with standard hearing assessments, though can be the cause of difficulties understanding speech in the presence of background noise. Recent studies have begun to explore the use of electrocochleography (ECochG) to detect this neural damage in humans. Such studies strive to aid in the development of a clinical tool for …

The Longitudinal Study Of Code-Switching In English-Instructed Spanish-English Bilingual Children, Molly K. Gasior

Graduate Theses/Dissertations

The population of bilingual children is growing in the U.S. Code-switching, a common occurrence in bilingual language production, is the use of words in the non-target language (e.g., English) when speaking the target language (e.g., Spanish). There are different approaches within the literature about how code-switching is dealt with. The purpose of this study is to longitudinally track changes in code-switching in English and Spanish narrative retell language samples, verify how code-switching impacts the lexical measure of number of different words, and whether code-switching may be indicative of Spanish language loss. Thirty-seven Spanish-English bilingual preschoolers who attended an English immersion …

Collective Action On Behalf Of Women: Testing The Conceptual Distinction Between Traditional Collective Action And Small Acts In College Women, Anca M. Miron, Thomas C. Ball, Nyla R. Branscombe, Monica Fieck, Cristinel Ababei, Serena Raymer, Baylee Tkaczuk, Megan M. Meives

Electrical and Computer Engineering Faculty Research and Publications

The current study examines the nature of actions that U.S. college women (N = 267) engage in to promote, protect, or enhance the welfare of other women. The study had two goals: 1) to distinguish between traditional forms of action (traditional collective action) and more informal, interpersonal, forms of action (small acts) among college women; and 2) to test whether the classic antecedents of collective action (gender identity, feminist identity, women’s activist identity, efficacy, appraisals of gender inequality, and injustice standards) are differentially predictive of these two types of participation. A confirmatory factor analysis provided strong support for these two …
