Humidity Effects on the Moment of Inertia in Solid Wood Baseball Bats

Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024) A recent surge in the home run rate in Major League Baseball has led to deeper scrutiny of all factors that might affect the properties that contribute to batted ball performance. For example, a special committee found that small changes in seam height, which were still well within acceptable manufacturing tolerances, led to a lower drag coefficient and increased home run rates for the same exit velocity and launch angle. While much of the increased scrutiny in baseball has focused on the balls, small changes in bat performance could have a similar effect. For example, Drane and Sherwood found a 1% increase in wood bat performance for bats conditioned in very humid air. For an exit velocity of 100 MPH and a launch angle of 30 degrees, batters can expect a 0.578 batting average and a 44.9% home run rate. A 1% increase in bat performance yields an exit velocity of 101 MPH, which increases the expected batting average to 0.661 with a 55.7% home run rate. In this work we investigate specifically the effect of various humidity conditions while storing wooden bats made from ash on their weight and inertia. This builds on previous work by Drane and Sherwood to decouple changes in bat performance from changes in the bat’s mass, balance, and moment of inertia. </p

From broadcast archive to language corpus: Designing and investigating a sociohistorical corpus from Desert Island Discs

The aims of this paper are twofold: i) to present the motivation and design of a sociohistorical corpus derived from the popular BBC Radio show, Desert Island Discs (DID); and ii) to illustrate the potential of the DID corpus (DIDC) with a case study. In an era of ever-increasing digital resources and scholarly interest in recent language change, there remains an enormous disparity between available written and spoken corpora. We describe how a corpus derived from DID contributes to redressing the balance. Treating DID as an example of a specialized register, namely, a ‘biographical chat show’, we review its attendant situational characteristics, and explain the affordances and design features of a sociolinguistic corpus sampling of the show. Finally, to illustrate the potential of DIDC for linguistic exploration of recent change, we conduct a case study on two pronouns with generic, impersonal reference, namely you and one

Guest speaker classifications for a corpus linguistic study of Desert Island Discs, by Smith and Waters (2018)

This file lists guest speakers who were sampled in a study by Nicholas Smith and Cathleen Waters of language use in the BBC Radio show Desert Island Discs. Speaker classifications by sex, age, occupation and education categories are given for three periods: early 1980s, late 1980s and early 2000s. Also included is the start time of each recording sampled. The research is to be published in ICAME Journal in May 2018.

Variation and change in a specialized register. A comparison of random and sociolinguistic sampling outcomes in Desert Island Discs.

Corpus-based studies of specialized registers typically sample texts using random methods as far as possible, but they disregard social characteristics of the speakers/writers. In contrast, in corpus-based studies of conversation and quantitative sociolinguistic studies, sampling is more typically designed to optimize social representation. To our knowledge, this study is the first to compare linguistic outcomes from random versus sociolinguistic sampling in a specialized register. Our data comes from the biographical radio chat show, Desert Island Discs (DID), at different points in time. We constructed two versions of a DID corpus: a sociolinguistic judgment sample based on guest demographics, and a random sample. We compare grammatical usage between them using an inductive (‘key POS-tags’) method and close manual analysis, uncovering some evidence of significant grammatical differences between the samples and differing patterns of diachronic change. We discuss the implications of our research for corpus design, representativeness and analysis in specialized registers
