Growth Mindsets Of Anxiety: Do The Benefits To Individual Flourishing Come With Societal Costs?, Crystal L. Hoyt, Jeni L. Burnette, Emma Nash, Whitney Becker, Joseph Billingsley

Psychology Faculty Publications

Believing anxiety can change is a predictor of wellbeing, in part, because such beliefs – known as growth mindsets – predict weaker threat appraisals, which in turn improves psychological functioning. However, feeling a sense of personal threat facilitates social activism, and thus growth mindsets may undermine such action. Across six studies (N = 1761), including cross-sectional and experimental approaches (3 pre-registered), growth mindsets predict flourishing, including wellbeing, resilience, and grit. We find that growth mindsets indirectly predict reduced activism against social threats through reduced threat appraisals, which are critical motivators of activism. The total effect linking growth mindsets to activism …

Rapid Enhancement Of Subcortical Neural Responses To Sine-Wave Speech, Fan-Yin Cheng, Can Xu, Lisa Gold, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

The efferent auditory nervous system may be a potent force in shaping how the brain responds to behaviorally significant sounds. Previous human experiments using the frequency following response (FFR) have shown efferent-induced modulation of subcortical auditory function online and over short- and long-term time scales; however, a contemporary understanding of FFR generation presents new questions about whether previous effects were constrained solely to the auditory subcortex. The present experiment used sine-wave speech (SWS), an acoustically-sparse stimulus in which dynamic pure tones represent speech formant contours, to evoke FFR_SWS. Due to the higher stimulus frequencies used in SWS, this …

The Effects Of Deepfakes And Synthetic Media On Communication Professionals, Axel Ebermann

Student Theses and Dissertations

The spread of misinformation and disinformation is regarded as one of the most salient challenges for communication professionals around the world.

Now, a new technology called "DeepFakes" or “Synthetic Media” has the potential to further uproot the infosphere. Artificial Intelligence (AI) will enable the mass creation of synthetic audio-visual content that resembles real videos, in which people will appear to say or do things they never actually said or did.

The existing literature predominantly focuses on three aspects of DeepFakes and Synthetic Media: the technical background, coverage of preexisting DeepFakes and possible solutions to combat the malicious use of the …

Droplet-Based Fuel Property Measurements, Wanjun Dang

LSU Doctoral Dissertations

Ongoing work to find renewable biofuels to function as drop-in replacements or blending components with gasoline has identified a large number of fuel candidates. Given the vast number of potential biomass-derived fuel molecules and limited sample sizes, screening tools are required to down-select candidate fuels having desired physical properties to ensure good engine performance. This work investigates approaches for rapid screening of candidate fuels using micro-liter sample sizes targeting four properties -- surface tension, viscosity, heat of vaporization (HOV), and vapor pressure. Measurement techniques for fuel properties are developed based on unit phenomena for liquid fuel droplets including droplet oscillation …

Demography, Growth And Robots In Advanced And Emerging Economies, Matteo Lanzafame

Fondazione Eni Enrico Mattei Working Papers

This paper provides estimates of the impact of demographic change on labor productivity growth, relying on annual data over 1961-2018 for a panel f 90 advanced and emerging economies. We find that increases in both the young and old population shares have significantly negative effects on labor productivity growth, working via various channels – including physical and human capital accumulation. Splitting the analysis for advanced and emerging economies shows that population ageing has a greater effect on emerging economies than on advanced economies. Extending the benchmark model to include a proxy for the robotization of production, we find evidence indicating …

Best Practice And Strategies To Effectively Support Dual Language Learners, Sydney Richardson

Graduate Teacher Education

According to Winsler et al. (2014), the fastest growing population of students entering preschool classrooms are considered Dual Language Learners (DLLs). Teachers are expected to teach these young learners, yet most of them feel unprepared to do so (Kibler, 2013). Many early childhood educators are unaware of the best practices and strategies to effectively support Dual Language Learners (DLLs) while preserving home language and culture (Hardin et al., 2010). In this review of literature, peer reviewed studies were examined for best practices teachers can utilize when working with children whose home language is not English. Results suggest that having children …

Fast Statistical Methods For The Global Qcd Analysis Of The Proton Structure, Xiaoxian Jing

Physics Theses and Dissertations

Parton distribution functions (PDFs) quantify probabilities to find partons (quarks and gluons) in a hadron as a function of the fraction x of the hadron’s momentum carried by the parton at a given energy scale. PDFs play a critical role in precision tests of the Standard Model in Higgs boson production and other electroweak processes at the Large Hadron Collider (LHC), and in searches for physics beyond the Standard Model. PDFs are obtained by the global QCD analysis, which fits theoretical predictions to experimental measurements. PDF fitting and post-analysis are computationally intensive. This dissertation discusses fast statistical methods for the …

The Attraction Of Fear And The Potential Therapeutic Value Of Horror Films, Mari-Peyton Kouchinsky

Educational Specialist, 2020-current

Cinematic horror has historically had a negative reputation among its peers even though it is a genre that commercially and financially thrives. There are many different perspectives as to what motivates an individual to willingly expose themselves to horror movies, ranging from psychological and metaphorical confrontation with repressed or socially unacceptable behaviors to fulfilling a somatic, thrill-seeking desire. Whatever the motivation, there is potential for harnessing both the psychological and physical reactions for therapeutic intervention. This paper aims to provide counselors with a synthesis of information on the potential therapeutic value of cinematherapy with horror movies, focusing on the relationship …
