Generalized Anxiety Symptoms And Interpersonal Self-Perceptions During Stressors: A Prospective Examination Of Psychological And Biological Stress, Jamie A. Lewis

Clinical Psychology Dissertations

Individuals with generalized anxiety disorder (GAD) symptoms endorse negative emotionality, psychosocial dysfunction, and biological dysregulation. Interpersonal dominance and affiliation have also been linked to GAD symptoms. Little research has examined individuals with GAD symptoms in terms of naturalistic stressors and chronic use of interpersonal behaviors. GAD symptoms, as well as lower dominance and affiliation, have been linked to hypothalamic-pituitary-adrenal (HPA) dysregulation. However, no studies have examined the unique and interacting contributions of GAD symptoms and interpersonal processes to chronic cortisol levels and distress. College students completed baseline measures of GAD symptoms, measures of interpersonal self-perceptions and distress for five weeks, …

Sealds: A Quantitative Content Analysis Of #Donttrashyourvote On Twitter, Viviek Patel

Honors Theses

Public relations research has slowly integrated with the study of advocacy organizations, but little research has integrated this and social movements. Using the pyramid model of mobilization-driven relationship-building social media based advocacy, this study employed a quantitative content analysis to examine the prevalence of previously identified communicative functions in social media messages by SEALDs. Unlike previous research on advocacy and health organizations, action messages were the most common. This study also investigated the influence of message type on audience engagement through retweets. The results indicate that information tweets had the most retweets. This study also analyzed how social movements recruit …

Predictors Of Paternal Postpartum Depression: A Meta-Analysis, Zachary Joseph Blackhurst

Theses and Dissertations

While major depression is a well-defined mental health condition, it's presentation can be vastly different across individuals and groups, and many factors impact one's vulnerability. A critical period of vulnerability to depression is the postpartum period. Despite the frequent assumption that postpartum conditions solely affect women, prevalence estimates of paternal postpartum depression (PPPD) are comparable with those of women. Similar to mothers, men experience significant biological and psychosocial changes following the birth of a child that contribute to the onset of postpartum depression. A growing body of research has identified many potential variables related to PPPD, yet there is no …

When Life Gives You Lemons: The Development And Validation Of The Resilience Scale For Older Adults, Claire A. Wilson

Electronic Thesis and Dissertation Repository

The study of resilience, or positive adaptation in the face of adversity, is important across the lifespan, but may be particularly relevant for older adults who tend to experience an increasing number of challenges. Traditionally, resilience assessment has largely focused on child and young-to-middle aged adult populations, and as such, the literature is lacking a validated resilience measure developed specifically for older adults. This dissertation aimed to improve the measurement of resilience in older populations by developing and validating a new resilience measure that is relevant and appropriate for older adults. In Study 1, a qualitative metasynthesis was conducted to …

A Walkthrough Of The Canadian Video Game Industry: An Economic Geography Perspective On The Digital Entertainment Frontier, Grant L. Morin

Electronic Thesis and Dissertation Repository

The video game industry has been examined since the 1970’s, yet individual country analysis from an economic geography perspective has been lacking. It is the contribution of this dissertation to utilize the agglomeration economy and location theory literature in its application to the Canadian video game industry.

To understand this industry, a mixed-method approach is used. Kernel density maps, standard deviational ellipses, and mapping processes were used to illustrate the dispersion and clustering patterns of studios in Canada. In addition, a Poisson regression was performed using count data of the number of video game firms in census metropolitan areas. The …

Psychological Predictors Of Injury In Collegiate Cheerleaders, Alexander Marchand

Electronic Thesis and Dissertation Repository

According to the revised stress-injury model (Williams & Andersen, 1998), greater life stress predicts greater vulnerability to athletic injury, with this relationship being strongest among athletes exhibiting competitive anxiety, less social support, and non-adaptive coping skills. This study tested the validity of this model among collegiate cheerleaders, an injury-prone athlete group. Ninety-two collegiate cheerleaders recorded instances of injury over 12 weeks. Measures of life stress, competitive anxiety, coping style, social support, and previous injury were obtained. Heightened negative life stress did not coincide with greater injury. A positive stress-injury relationship was observed among cheerleaders reporting high avoidance coping. A negative …

Diagnosing Housing Fever With An Econometric Thermometer, Shuping Shi, Peter C. B. Phillips

Cowles Foundation Discussion Papers

Housing fever is a popular term to describe an overheated housing market or housing price bubble. Like other financial asset bubbles, housing fever can inflict harm on the real economy, as indeed the US housing bubble did in the period following 2006 leading up to the general financial crisis and great recession. One contribution that econometricians can make to minimize the harm created by a housing bubble is to provide a quantitative `thermometer’ for diagnosing ongoing housing fever. Early diagnosis can enable prompt and effective policy action that reduces long term damage to the real economy. This paper provides a …

When Bias Contributes To Variance: True Limit Theory In Functional Coefficient Cointegrating Regression, Peter C. B. Phillips, Ying Wang

Cowles Foundation Discussion Papers

Limit distribution theory in the econometric literature for functional coefficient cointegrating (FCC) regression is shown to be incorrect in important ways, influencing rates of convergence, distributional properties, and practical work. In FCC regression the cointegrating coefficient vector \beta(.) is a function of a covariate z_t. The true limit distribution of the local level kernel estimator of \beta(.) is shown to have multiple forms, each form depending on the bandwidth rate in relation to the sample size n and with an optimal convergence rate of n^{3/4} which is achieved by letting the bandwidth have order 1/n^{1/2}.when z_t is scalar. Unlike stationary …

The Development Of Attitudes Toward Scientific Models During A Participatory Modeling Process – The Impact Of Participation And Social Network Structure, Taylor Goelz, T. W. Hartley, Andrew M. Scheld, Inga Carboni

VIMS Articles

Scientific models are increasingly being used to support participatory natural resources management decision making processes. These models allow stakeholders and scientists to explore potential policy and management options and can help facilitate discussion surrounding concerning uncertainty and different sources of knowledge. The unique benefits of participatory modeling processes, however, are contingent upon stakeholders understanding of, engagement with, and willingness to use the scientific models as sources of knowledge and information. Little is known, however, about how stakeholders view scientific models within these processes. We examined changes in stakeholders’ attitudes toward scientific models over the course of OysterFutures, a 2-year, facilitated …

Bootstrap Inference For Quantile Treatment Effects In Randomized Experiments With Matched Pairs, Liang Jiang, Xiaobin Liu, Peter C. B. Phillips, Yichong Zhang

Cowles Foundation Discussion Papers

This paper examines methods of inference concerning quantile treatment effects (QTEs) in randomized experiments with matched-pairs designs (MPDs). We derive the limit distribution of the QTE estimator under MPDs, highlighting the difficulties that arise in analytical inference due to parameter tuning. We show that the naïve weighted bootstrap fails to approximate the limit distribution of the QTE estimator under MPDs because it ignores the dependence structure within the matched pairs.To address this difficulty we propose two bootstrap methods that can consistently approximate the limit distribution: the gradient bootstrap and the weighted bootstrap of the inverse propensity score weighted (IPW) estimator. …

Common Bubble Detection In Large Dimensional Financial Systems, Ye Chen, Peter C. B. Phillips, Shuping Shi

Cowles Foundation Discussion Papers

Price bubbles in multiple assets are sometimes nearly coincident in occurrence. Such near-coincidence is strongly suggestive of co-movement in the associated asset prices and likely driven by certain factors that are latent in the financial or economic system with common effects across several markets. Can we detect the presence of such common factors at the early stages of their emergence? To answer this question, we build a factor model that includes I(1), mildly explosive, and stationary factors to capture normal, exuberant, and collapsing phases in such phenomena. The I(1) factor models the primary driving force of market fundamentals. The explosive …

High-Dimensional Vars With Common Factors, Ke Miao, Peter C.B. Phillips, Liangjun Su

Cowles Foundation Discussion Papers

This paper studies high-dimensional vector autoregressions (VARs) augmented with common factors that allow for strong cross section dependence. Models of this type provide a convenient mechanism for accommodating the interconnectedness and temporal co-variability that are often present in large dimensional systems. We propose an `1-nuclear-norm regularized estimator and derive non-asymptotic upper bounds for the estimation errors as well as large sample asymptotics for the estimates. A singular value thresholding procedure is used to determine the correct number of factors with probability approaching one. Both the LASSO estimator and the conservative LASSO estimator are employed to improve estimation precision. The conservative …

The Human Cerebellum Has Almost 80% Of The Surface Area Of The Neocortex, Martin I. Sereno, J. Rn Diedrichsen, Mohamed Tachrount, Guilherme Testa-Silva, Helen D Arceuil, Chris De Zeeuw

Brain and Mind Institute Researchers' Publications

© 2020 National Academy of Sciences. All rights reserved. The surface of the human cerebellar cortex is much more tightly folded than the cerebral cortex. It was computationally reconstructed for the first time to the level of all individual folia from multicontrast high-resolution postmortem MRI scans. Its total shrinkage-corrected surface area (1,590 cm2) was larger than expected or previously reported, equal to 78% of the total surface area of the human neocortex. The unfolded and flattened surface comprised a narrow strip 10 cm wide but almost 1 m long. By applying the same methods to the neocortex and cerebellum of …

Joshua Leffler, Péter Kovács, Jason D. Clark, David E. Clay, Jessica Ulrich-Schad

Sociology, Social Work and Anthropology Faculty Publications

To improve the economic and environmental sustainability of agriculture, information is needed on how to target research, teaching, and outreach programs. However, conducting survey research in general, and with agricultural producers specifically, is increasingly challenging given issues such as declining response rates and limited resources. While studies examining the best practices for promoting higher response rates exist, few focus explicitly on agricultural producers. In three separate surveys conducted with agricultural producers in South Dakota in 2018 and 2019, we included experiments testing how token pre-incentives, a research partnership, and response mode options impacted response rates. We also examined how sample …

The Inequities Of Job Loss And Recovery Amid The Covid-19 Pandemic, Rogelio Saenz, Corey Sparks

Carsey School of Public Policy

In this policy brief, authors Rogelio Sáenz and Corey Sparks discuss the wide variations in unemployment and the level of job loss during the COVID-19 pandemic across the nation’s demographic groups that have historically suffered disparities in the workforce, including persons of color, women, and immigrants. It is particularly unfortunate that the calamity of the pandemic comes on the heels of major improvements in job prospects that these groups made over the last decade, as the workforce emerged from the Great Recession.

The benefits associated with the CARES Act of March 2020 expired in July, leaving tens of millions of …

“I Went Into This As One Person, And Then Came Out A Totally Different Person”: Native Lgbtq2s+ Young Adults’ Conceptions Of Trauma, Rachel M. Schmitz, Ruby Charak

Psychological Science Faculty Publications and Presentations

Intersecting sources of stigma influence harmful mental health outcomes for lesbian, gay, bisexual, transgender, queer, and Two-Spirit (LGBTQ2S+) young adults (YA) of color as they must manage multiple oppressions. Experiencing both mental health challenges and victimization, LGBTQ2S+ YA of color struggle with distinctive psychological traumas. There is a critical need to determine how certain groups of LGBTQ2S+ YA of color’s marginalized social statuses shape trauma understandings. Native LGBTQ2S+ people in general endure diverse forms of oppression and trauma, such as histories of colonialism, contemporary racism, sexism, homophobia, and classism. Understanding the subjective interpretations of violence and trauma among Native LGBTQ2S+ …

The Role Of Cost, Scale, And Property Attributes In Landowner Choice Of Stormwater Management Option., W. Bowman Cutter, Alexander Pusch

Pomona Economics

Cities throughout the world are experimenting with Low Impact Development (LID) strategies to replace ecosystem services degraded by urbanization. Stormwater management may need both centralized/publicly-managed infrastructure and decentralized provision by landowners. For landowners to participate in these programs they will need some latitude in the choice of techniques and siting. However, these landowner choices will affect the bundle of ecosystem services provided (such as infiltration, aesthetics, pollution filtering, and others) as well as their spatial distribution. We studied the Santa Monica (CA) stormwater regulations that require stormwater management on a large portion of development and redevelopment but allow a significant …
