#Dearcongress: A Public Letter, Elisabeth A. Montemurro, David Kamerer

School of Communication: Faculty Publications and Other Works

#DearCongress was prevalent within Twitter discourse during the 2013 U.S. government shutdown. The hashtag allowed a community to form by assembling around a common topic. What a group communicates through social networks cannot be separated from its context. This micro-analysis of #DearCongress utilizes discourse tracing through word clouds, guided by Bruns & Burgess’ concept of an ad hoc public. By looking at the commentary during a political and time stamped event, we can better understand the role discourse plays in group formation, evolution, and impact.

Bodyweight Perceptions Among Texas Women: The Effects Of Religion, Race/Ethnicity, And Citizenship Status, Aida Ramos, Gabriel A. Acevedo, Andrea L. Ruiz

Faculty Publications - Department of Sociology

Despite previous work exploring linkages between religious participation and health, little research has looked at the role of religion in affecting bodyweight perceptions. Using the theoretical model developed by Levin et al. (Sociol Q 36(1):157–173, 1995) on the multidimensionality of religious participation, we develop several hypotheses and test them by using data from the 2004 Survey of Texas Adults. We estimate multinomial logistic regression models to determine the relative risk of women perceiving themselves as overweight. Results indicate that religious attendance lowers risk of women perceiving themselves as very overweight. Citizenship status was an important factor for Latinas, with noncitizens …

End Of Program Assessments And Their Association With Early Career Success In Lis, Susan R. Rathbun-Grubb

Faculty Publications

Analyses of North American LIS program alumni survey data indicate that the completion of any end of program assessment (EPA) or capstone is associated with certain early-career success measures. Using data collected in the Workforce Issues in Library and Information Science 2 project (WILIS 2), we examined the type of EPAs (internships, portfolios, theses, etc.) completed by students and assessed whether there are relationships between their completion and the following outcomes: length of time to secure employment after graduation, acquisition of managerial or leadership roles, job/ career satisfaction, and participation in professional and leadership activities. We also assessed the graduates’ …

How Narrative Focus And A Statistical Map Shape Health Policy Support Among State Legislators, Jeff Niederdeppe, Sungjong Roh, Caitlin Dreisbach

Research Collection Lee Kong Chian School Of Business

This study attempts to advance theorizing about health policy advocacy with combinations of narrative focus and a statistical map in an attempt to increase state legislators’ support for policies to address the issue of obesity by reducing food deserts. Specifically, we examine state legislators’ responses to variations in narrative focus (individual vs. community) about causes and solutions for food deserts in U.S. communities, and a statistical map (presence vs. absence) depicting the prevalence of food deserts across the United States. Using a Web-based randomized experiment (N = 496), we show that narrative focus and the statistical map interact to produce …

Delusional Disorder: Treatment And The Restoration Of Adjudicative Competence, Martin Kassen

Dissertations, Theses, and Capstone Projects

Delusional disorder has long been recognized in the psychiatric nomenclature, however, low prevalence rates and prevailing clinical views about the seemingly refractory nature of delusional disorder have restricted data on clinical treatment outcomes for this illness. Similar perspectives have been noted in forensic settings where minimal data is available to guide standards of care for incompetent to stand trial (IST) delusional pretrial defendants. Rationale. While the factors explicated in Sell provide guidelines for the involuntary medication of defendants found IST, numerous questions are left unanswered regarding the restorability of pretrial delusional detainees. The proposed study investigated the competency restoration rates …

Voicing The Other: Mock Aave On Social Media, Hanna L. Smokoski

Dissertations, Theses, and Capstone Projects

This project looks at the use on social media sites of features of African American Vernacular English by nonspeakers of it. This outgroup use of AAVE does not require nor reflect any true proficiency with the variety, but instead is often used to exaggerate the social distance between the stylizers using it on social media and the marginalized people for whom AAVE is a genuine mode of communication. Through double indexicality, nonspeakers of AAVE use features of it to annex certain positive qualities associated with Black or hip hop culture—toughness, coolness, an anti-establishment stance—for themselves, while reproducing negative stereotypes of …

What Are The Barriers And Conduits To College Success For Academically Vulnerable Students?, Marisol Zacarias

Dissertations, Theses, and Capstone Projects

What are the barriers and conduits to college success for academically vulnerable students? Employing two theoretical frameworks—ecological systems theory and intersectionality—this thesis interrogates two concepts: grit/persistence and support. To do this, data were collected from a group of academically vulnerable students of color from low-income backgrounds via two methodologically different venues: a focus group in 2012 and follow-up one-on-one interviews two years later, in 2014. From the focus group, two themes emerged: discouraging messages and hope. Two years later the follow-up one-on-one interviews produced two additional themes: balancing act and support. Building positive peer relationships was identified as a key …

Re-Framing Informal Family Caregiving, Magdalena T. Ornstein-Sloan

Dissertations, Theses, and Capstone Projects

Informal family caregivers are the backbone of the long-term care system, providing an estimated 80% of the long-term care in the United States. Caregivers provide care to people with disabilities, the ill and older adults, often with little to no outside assistance from the formal long-term care system. Although caregivers receive attention in the academic literature, mainstream media and within public policy and services development, caregiver services continue to remain underutilized. The focus on service provision has various goals, including the desire to lessen the burden caregivers experience by providing services so they can provide care at home longer than …

Status Signaling And The Characterization Of A Chirp-Like Signal In The Weakly Electric Fish Steatogenys Elegans, Caitlin E. Field

Dissertations, Theses, and Capstone Projects

Sensory systems are critical to both exploratory and communicatory processes, the study of which is critical to our understanding of how animals perceive and respond to their environments. In weakly electric fishes the electrosensory system is utilized for both of these purposes. One type of communication, status signaling, is widespread across taxa and frequently hormonally modulated. This hormonal modulation keeps the signal honest, wherein the status of the sender and the production of the status signal itself are both hormone dependent. We investigated exploratory and communicatory strategies of the electromotor system in pulse-type gymnotiforms, with a focus on status communication …

Re-Examining The Bilingual Advantage On Interference-Control And Task-Switching Tasks: A Meta-Analysis, Seamus Donnelly

Dissertations, Theses, and Capstone Projects

A much-debated topic in psycholinguistics is whether lifelong bilingualism enhances executive functions (EF), the set of higher-order cognitive processes involved in the control of thought and action. Several researchers have predicted bilingual advantages on various EF tasks, especially interference-control and task-switching tasks. Many studies have tested these predictions, but results have proven unreliable. As a complementary approach to recent quantitative syntheses on this topic, the present dissertation tests whether the bilingual advantage is moderated by a number of theoretically significant variables: dependent variable (DV), task, age, age of L2 acquisition and lab.

Two meta-analyses were conducted. Study 1 considered interference-control …

Patients’ Perspectives On Health Care In The United States: Florida, R. J. Blendon, J. M. Benson, Caitlin L. Mcmurtry, J. M. Sayde

Brown School Faculty Publications

The landscape and experience of health care in the United States has changed dramatically in the last two years. January 2014 saw insurance purchased on state exchanges and the federal marketplace go into effect, the start of the Affordable Care Act’s individual mandate and its accompanying subsidies and tax credits for qualifying Americans, discrimination protections, including pre-existing conditions, for those seeking to buy health insurance, and the implementation of essential health benefits for all plans sold through the insurance marketplace.

Population Dynamics And Vulnerability Reduction: The Role Of Non-Profit Organizations Following The 2011 Earthquake In Christchurch, New Zealand, Nicole Suzanne Hutton

USF Tampa Graduate Theses and Dissertations

With the adoption of neo-liberal policies and the decline in social welfare, non-profit organizations have been increasingly integrated into public service provision. Such changes raise questions regarding formal policies and access for marginalized populations, no more so than in disaster settings as formal disaster management of sexual health services are still vague. This study identifies the role of non-profit organizations in providing public health and social services through the lens of sexual health commitments following the September 2010 Darfield Earthquake and subsequent major aftershock during February 2011 in Christchurch, New Zealand. The primary goals of this study were three fold, …

A Reflexive Eye On A Collaborative Action Research Project In School, Kitt Lyngsnes

The Qualitative Report

This article presents a reflexive analysis of a collaborative action research project based on the “Nordic tradition” of action research. In this project I, in the role of researcher, worked with a team of four teachers in a Norwegian primary/lower secondary school to develop teaching practice focused on students’ learning. I have retrospectively analysed data from my research diary, meetings and interviews. The article describes how the collaboration and the relationship between the teacher team and the researcher developed, and how this process contributed to the teachers’ professional development. The results shed light on the complexity of teacher- researcher- relationships, …

Super Mario Brothers And Sisters: Associations Between Coplaying Video Games And Sibling Conflict And Affection, Sarah Coyne, Alexander C. Jensen, Nathan J. Smith, Daniel H. Erickson

Faculty Publications

Video games can be played in many different contexts. This study examined associations between coplaying video games between siblings and levels of affection and conflict in the relationship. Participants were 508 adolescents (M age = 16.31 years of age, SD = 1.08) who completed questionnaires on video game use and sibling relationships. Participants were recruited from a large Northwestern city and a moderate city in the Mountain West of the United States. Video games played between siblings were coded by an independent sample to assess levels of physical aggression and prosocial behavior in each game. Playing video games with …

Facilitating A Whole-Life Approach To Career Development: The Role Of Organizational Leadership, Michael L. Litano, Debra A. Major

Psychology Faculty Publications

This article focuses on the whole-life approach to career development. A review of the ways in which career paths have been conceptualized over time demonstrates that increasing consideration has been given to nonwork factors (i.e., personal life and family life) in defining careers. The whole-life perspective on career development acknowledges that employees are striving for opportunities for professional development as well as individualized work-life balance, which changes over the life course. Although the careers literature has emphasized interorganizational mobility as the primary mechanism for achieving these goals, whole-life career development can also be achieved within a single organization when organizational …

Quantity Discounts And Capital Misallocation In Vertical Relationships, Ken Onishi

Research Collection School Of Economics

I study transactions between aircraft manufacturers and airlines as well as airlines' utilization of their fleet. Aircraft production is characterized by economies of scale via learning-by-doing, which creates a trade-off between current profit and future competitive advantage in the aircraft market. The latter consideration makes large buyers more attractive than small buyers and induces quantity discounts. The resulting nonlinear pricing strategy may distort both production and allocation in favor of large buyers. In the data, there is a negative correlation between the size of aircraft orders and the per-unit price, and a positive correlation between the price paid and the …

Common Threshold In Quantile Regressions With An Application To Pricing For Reputation, Liangjun Su, Pai Xu, Heng Ju

Research Collection School Of Economics

The paper develops a systematic estimation and inference procedure for quantile regression models where there may exist a common threshold effect across different quantile indices. We first propose a sup-Wald test for the existence of a threshold effect, and then study the asymptotic properties of the estimators in a threshold quantile regression model under the shrinking-threshold-effect framework. We consider several tests for the presence of a common threshold value across different quantile indices and obtain their limiting distributions. We apply our methodology to study the pricing strategy for reputation via the use of a dataset from Taobao.com. In our economic …

Testing For Monotonicity In Unobservables Under Unconfoundedness, Stefan Hoderlein, Liangjun Su, Halbert White, Thomas Tao Yang

Research Collection School Of Economics

Monotonicity in a scalar unobservable is a common assumption when modeling heterogeneity in structural models. Among other things, it allows one to recover the underlying structural function from certain conditional quantiles of observables. Nevertheless, monotonicity is a strong assumption and in some economic applications unlikely to hold, e.g., random coefficient models. Its failure can have substantive adverse consequences, in particular inconsistency of any estimator that is based on it. Having a test for this hypothesis is hence desirable. This paper provides such a test for cross-section data. We show how to exploit an exclusion restriction together with a conditional independence …

Granger Causality And Structural Causality In Cross-Section And Panel Data, Xun Lu, Liangjun Su, Halbert White

Research Collection School Of Economics

Granger non-causality in distribution is fundamentally a probabilistic conditional independence notion that can be applied not only to time series data but also to cross-section and panel data. In this paper, we provide a natural definition of structural causality in cross-section and panel data and forge a direct link between Granger (G-) causality and structural causality under a key conditional exogeneity assumption. To put it simply, when structural effects are well defined and identifiable, G- non-causality follows from structural non-causality, and with suitable conditions (e.g., separability or monotonicity), structural causality also implies G-causality. This justifies using tests of G- non-causality …

Are House Prices Driven By Capital Flows? Evidence From Singapore, Hwee Kwan Chow, Taojun Xie

Research Collection School Of Economics

This paper investigates whether real house price appreciations can be attributed to the surge in real capital inflows into Singapore. We proxy capital flows by using the amount of foreign direct investments (FDI) to real estate capturing the foreign purchases of property in Singapore which we deflate by the private residential property price index. Notwithstanding the absence of a cointegrating relationship, our results support the hypothesis that lagged short term fluctuations in capital inflows are positively associated with the growth rates of house prices over the last decade. We also provide evidence that macroprudential measures implemented by Singapore reduced the …

Measurement Invariance Of The Brief Multidimensional Student’S Life Satisfaction Scale Among Adolescents And Emerging Adults Across 23 Cultural Contexts, Amina Abubakar, Et Al, Samantha Sim

Research Collection Lee Kong Chian School Of Business

There is hardly any cross-cultural research on the measurement invariance of the Brief Multidimensional Students’ Life Satisfaction Scales (BMSLSS). The current article evaluates the measurement invariance of the BMSLSS across cultural contexts. This cross-sectional study sampled 7,739 adolescents and emerging adults in 23 countries. A multi-group confirmatory factor analysis showed a good fit of configural and partial measurement weights invariance models, indicating similar patterns and strengths in factor loading for both adolescents and emerging adults across various countries. We found insufficient evidence for scalar invariance in both the adolescents’ and the emerging adults’ samples. A multi-level confirmatory factor analysis indicated …

Is Urban Food Demand In The Philippines Different From China?, Tomoki Fujii

Research Collection School Of Economics

Food is an essential good, and thus understanding its demand is important for the formulation of sound agricultural policies and developing sustainable agricultural business. A timely analysis of food demand is important because it can change over time not only because prices and incomes change but also because people’s taste itself also change. However, even in countries where food accounts for a sizable share of expenditure or where the agricultural sector accounts for a large share of output, careful analysis of food demand is often not readily available. In this study, we analyze the food demand in urban Philippines and …

Constrained Inefficiency And Optimal Taxation With Uninsurable Risks, Piero Gottardi, Atsushi Kajii, Tomoyuki Nakajima

Research Collection School Of Economics

When individuals' labor and capital income are subject to uninsurable idiosyncratic risks, should capital and labor be taxed, and if so how? In a two-period general equilibrium model with production, we derive a decomposition formula of the welfare effects of these taxes into insurance and distribution effects. This allows us to determine how the sign of the optimal taxes on capital and labor depend on the nature of the shocks and the degree of heterogeneity among consumers' income, as well as on the way in which the tax revenue is used to provide lump-sum transfers to consumers. When shocks affect …

Funding Resilient Infrastructure In New Jersey: Attitudes Following A Natural Disaster, Robert B. Noland, Marc D. Weiner, Michael R. Greenberg

Mineta Transportation Institute

Recent major natural disasters in New Jersey have demonstrated the need to increase the resilience of transportation infrastructure. This research examines public attitudes toward revenue sources that can be dedicated to protecting vulnerable areas, most notably the transportation linkages on which the state depends. A statewide survey was conducted to gather data approximately four months following Superstorm Sandy, the costliest natural disaster in the state’s history. The authors’ objective was to sample public attitudes while the impacts of the disaster were still fresh. They found little support for temporary tax increases to improve resiliency, with the most positive support for …
