Capacity Utilization Rates across NFL Stadiums

Attendance at NFL games has steadily increased for the past half-decade. Teams and the league as a whole have a direct interest in learning what brings fans to the games. This research studies the economic/demographic factors and team characteristics that affect stadium capacity utilization rates of NFL teams over the period from 2012 to 2016. Among the economic/demographic factors, we find that the more populated the city is where a team is located, the higher the team’s stadium capacity utilization rate. Among the team characteristics, our results indicate that having a new stadium, having more professional teams in a city, and the team’s winning percentage all affect the stadium capacity utilization rate

Sensationalized Surveillance: Campus Reform and the Targeted Harassment of Faculty [post-print]

Campus Reform is a right-wing website that hires students to write articles accusing universities and faculty members of “liberal bias.” These pieces circulate widely within the right-wing media ecosystem, where they can inspire self-deputized online vigilantes to harass faculty members and college administrators to sanction their faculty members. We argue that Campus Reform is part of a well-funded and well-organized panoptic network that engages in the sensationalized surveillance of faculty. This paper first develops our concept of sensationalized surveillance. We then offer a comprehensive institutional history of Campus Reform – demonstrating that it originates with, and continues to operate as, a conservative political technology. We then explore the details of how this surveillance apparatus functions and conclude by examining the disciplining effects Campus Reform has on faculty

U.S. Multinational Services Companies: Effects of Foreign Affiliate Activity on U.S. Employment

This working paper examines the effect that U.S. services firms’ establishment abroad has on domestic employment. Whereas many papers have explored the employment effects of foreign direct investment in manufacturing, few have explored the effects of services investment. We find that services multinationals’ activities abroad increase U.S. employment by promoting intrafirm exports from parent firms to their foreign affiliates. These exports support jobs at the parents’ headquarters and throughout their U.S. supply chains. Our findings are principally based on economic research and econometric analysis performed by Commission staff, services trade and investment data published by the Bureau of Economic Analysis, and employment data collected by the Bureau of Labor Statistics. In the aggregate, we find that services activities abroad support nearly 700,000 U.S. jobs. Case studies of U.S. multinationals in the banking, computer, logistics, and retail industries provide the global dimensions of U.S. MNC operations and identify domestic employment effects associated with foreign affiliate activity in each industry

Analysis of Emergent Electronic Properties of Self-Assembling Nucleopeptides

Biomolecular structures are held together by a complex network of molecular interactions that direct assembly and stabilize structures. In order to translate the fundamental molecular interactions of biomolecules into the design of functional biomaterials, we have developed a model system that integrates nucleic acids and self- assembling peptides. These nucleopeptides serve as a small-model system for the study of the non-covalent molecular interactions involved in biomolecule self-assembly. We have scaled up and expanded the analysis of our original nucleopeptide library in order to further characterize these assembled structures. Infrared (IR) spectroscopy, Atomic Force Microscopy (AFM), and Transmission Electron Microscopy (TEM) were utilized to characterize the assembly structure and image the supramolecular morphology of the nucleopeptides. The emergent electronic properties of the nucleopeptide assemblies were analyzed by Electrical Impedance Spectroscopy (EIS). Collectively, these studies on nucleopeptide supramolecular structure assembly will contribute to the design of functional biomaterials with the potential to conduct and store electrical charge

The Analysis and Application of the Emergent Electronic Properties of Self Assembling Nucleopeptide Systems

Faculty Research Day 2018: Undergraduate Student Poster Honorable MentionBiomolecular structures are held together by a complex network of molecular interactions that direct assembly and stabilize structures. In order to translate the fundamental molecular interactions of biomolecules into the design of functional biomaterials, we have developed a model system that integrates nucleic acids and self-assembling peptides. These nucleopeptides serve as a small-model system for the study of the non-covalent molecular interactions involved in biomolecule self-assembly measured through impedance. The peptides are in this case our system of electronic circuit. The emergent electronic properties found in most of our 21 samples, which were measured by Electrical Impedance Spectroscopy (EIS) and analyzed by ZMAN software shows promise. This is because one of the most frequent application to show up was Battery and Supercapacitor which can be used in Biosensors

Sleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studies

Background Sleep disturbance has been described as a ‘hallmark’ symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain. Objective To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraph-derived sleep measures. Method Case-control studies comparing participants with current PTSD to those without PTSD were eligible for inclusion. Sleep parameters of interest were: (1) total sleep time; (2) sleep onset latency; (3) wake after sleep onset (WASO); and (4) sleep efficiency. Data were meta-analysed as standardised mean differences (SMDs) and potential sources of heterogeneity were explored through meta-regression. Six actigraphy studies with 405 participants were included. Results There was no evidence of a statistically significant difference between those with and without PTSD in total sleep time (SMD 0.09, 95%CI −0.23 to 0.42); WASO (SMD 0.18, 95%CI −0.06 to 0.43); sleep latency (SMD 0.32, 95%CI −0.04 to 0.69); or sleep efficiency (SMD −0.28, 95%CI −0.78 to 0.21). Conclusions Further high-quality research is required to determine whether there is a true difference in sleep between those with and without PTSD

Clockface polygons and the collective joy of making mathematics together

The social and embodied nature at the heart of all knowing, doing, and learning contrasts with the images that pervade our cultural imagination of mathematical work as a solitary, cognitive activity. This article describes a playful experiment by the author group to do collective mathematics, in an extended effort to construct alternative images, instincts, and practices for ourselves. We present a pair of episodes of mathematical exploration that come from our work together and that we have seen as an early success, intimating features of a stabilized collective mathematics that we hope to continue pursuing. Coming from a single investigation of our group, these episodes offer narrative accounts of the parallel inquiries of subgroups, working to define and characterize a mathematical space we had collectively identified, and then to formulate and investigate conjectures about that space. The narratives are followed by a discussion of themes within and across them and reflections on their significance as a step toward self-organized collective mathematics
