Butting Heads: Tackling Football Concussion and Prevention

Hundreds of thousands of sports concussions occur each year in the United States, and almost half of them are the result of a football injury. Even though they may not initially appear serious, concussions can lead to extreme cognitive impairments in those affected. This article highlights the importance of treating concussions properly and educating coaches, parents, and athletes on the value of allowing young athletes to take the time they need to fully recover

Using Random Forests to Describe Equity in Higher Education: A Critical Quantitative Analysis of Utah’s Postsecondary Pipelines

The following work examines the Random Forest (RF) algorithm as a tool for predicting student outcomes and interrogating the equity of postsecondary education pipelines. The RF model, created using longitudinal data of 41,303 students from Utah\u27s 2008 high school graduation cohort, is compared to logistic and linear models, which are commonly used to predict college access and success. Substantially, this work finds High School GPA to be the best predictor of postsecondary GPA, whereas commonly used ACT and AP test scores are not nearly as important. Each model identified several demographic disparities in higher education access, most significantly the effects of individual-level economic disadvantage. District- and school-level factors such as the proportion of Low Income students and the proportion of Underrepresented Racial Minority (URM) students were important and negatively associated with postsecondary success. Methodologically, the RF model was able to capture non-linearity in the predictive power of school- and district-level variables, a key finding which was undetectable using linear models. The RF algorithm outperforms logistic models in prediction of student enrollment, performs similarly to linear models in prediction of postsecondary GPA, and excels both models in its descriptions of non-linear variable relationships. RF provides novel interpretations of data, challenges conclusions from linear models, and has enormous potential to further the literature around equity in postsecondary pipelines

The politics of historical economics: Wilhelm Roscher on democracy, socialism and Caesarism

Wilhelm Friedrich Georg Roscher (1817-94) is generally remembered as a significant nineteenth-century German political economist and a contributor to the “German Historical School of Economics.” His work is usually placed in the context of a larger narrative about the development of economic thought. Yet intellectual historians have rarely noticed that, for Roscher, Staatswirthschaft or Nationalökonomie were subordinate to a larger science of politics, and few have engaged with the substance of his political thought, as opposed to his political economy. The aim of this article is to provide an interpretation of Roscher as a political thinker, exploring his concern that nineteenth-century Europe’s economically-advanced societies, characterised by an unstable combination of democratic sovereignty, deep socio-economic inequality, and a centralised state apparatus, would soon find themselves at the mercy of “military tyranny” or “Caesarism.” It underlines the ways in which Roscher’s preoccupation with ancient history fed into his estimation of nineteenth-century politics, and also examines his comparative assessment of democracy’s prospects in Britain, France, and the United States. The argument has some wider implications for the nineteenth-century reception of classical thought and historiography, for the shifting preoccupations of German liberalism between Vormärz and the Kaiserreich, and for wider nineteenth-century assessments of the future of democracy

The strong Lefschetz property for coinvariant rings of finite reflection groups

In this paper we prove that a deformed tensor product of two Lefschetz algebras is a Lefschetz algebra. We then use this result in conjunction with some basic Schubert calculus to prove that the coinvariant ring of a finite reflection has the strong Lefschetz property.Comment: 31 page
