Interview with Robert O\u27Brien, January 9, 2006

Robert O\u27Brien was interviewed on January 9, 2006 by Michael J. Birkner about his military service during World War II and his years as a student at Gettysburg College. He discusses his childhood and time at Muhlenberg College, before he enlisted in the US Navy Air Corps and served at the Naval Air Station in Jacksonville, Florida. After the war he came to Gettysburg on a basketball scholarship. He discusses his experience as a physics major, fraternity brother, and college athlete.

The Unity of the Laches

On the level of ideas the dialogue remains incomplete. A satisfactory conception of courage is never formulated. On the level of personalities, however, there is a solution, in the person of Socrates. He has fought bravely at Delium and has matched or surpassed Laches in steadfastness. But he can also examine courage rationally and realizes the importance of knowledge to virtue, like Nicias. Neither Laches nor Nicias is fully worthy as a person of courage, as Socrates is. But there is a harmony between the incomplete definitions they offer and their own characters. The unity of the Laches is both a piece of dramatic literature and an essay in philosophy, and the purposes of the dramatist and the philosopher are in perfect agreement

An Assessment of the Coastal Training Program Needs of the ANERR Region

A series of focus groups were conducted throughout northwest Florida to obtain input from coastal decision-makers into the design and development of a coastal resources management training program for the Apalachicola National Estuarine Research Reserve (ANERR). The focus groups were comprised of a cross section of coastal and environmental professionals who make decisions affecting coastal and watershed areas. The focus group decision-makers were primarily employed in the public sector (federal, state, local, governmental, nonprofit, or academic), with nearly half of the participants having between six and 15 years of professional experience

Rating News Claims: Feature Selection and Evaluation

News claims that travel the Internet and online social networks (OSNs) originate from different, sometimes unknown sources, which raises issues related to the credibility of those claims and the drivers behind them. Fact-checking websites such as Snopes, FactCheck, and Emergent use human evaluators to investigate and label news claims, but the process is labor- and time-intensive. Driven by the need to use data analytics and algorithms in assessing the credibility of news claims, we focus on what can be generalized about evaluating human-labeled claims. We developed tools to extract claims from Snopes and Emergent and used public datasets collected by and published on those websites. Claims extracted from those datasets were supervised or labeled with different claim ratings. We focus on claims with definite ratings—false, mostly false, true, and mostly true, with the goal of identifying distinctive features that can be used to distinguish true from false claims. Ultimately, those features can be used to predict future unsupervised or unlabeled claims. We evaluate different methods to extract features as well as different sets of features and their ability to predict the correct claim label. By far, we noticed that OSN websites report high rates of false claims in comparison with most of the other website categories. The rate of reported false claims is higher than the rate of true claims in fact-checking websites in most categories. At the content-analysis level, false claims tend to have more negative tones in sentiments and hence can provide supporting features to predict claim classification

Statistical Analyses Cannot be Divorced From Archaeological Theory: A Reply to Potter

Potter criticizes our experimental study of the roles played by indirect bias and guided variation in shaping prehistoric Great Basin projectile point variation. His criticisms are technically correct from the standpoint of statistical convention, but he fails to understand the theoretical rationale of our study. Without such an understanding, hi s assertion that our conclusions are questionable is incorrect. Here we point out again (1) how our experimental work bridges the gap between cultural-transmission theory and the empirical record and (2) why our conclusions are indeed valid

Chronometers and Units in Early Archaeology and Paleontology

Early in the nineteenth century, geologist Charles Lyell reasoned that successively older faunas would contain progressively more extinct species and younger faunas relatively more extant species. The present, with one-hundred percent extant species, was the chronological anchor. In archaeology a similar notion underpins the direct historical approach: Successively older cultures will contain progressively fewer of the cultural traits found in extant cultures and relatively more prehistoric traits. As in Lyell\u27s scheme, the chronological anchor is the present. When A. L. Kroeber invented frequency seriation in the second decade of the twentieth century, he retained the present as a chronological anchor but reasoned that the oldest cultural manifestation would contain the highest percentage of a variant, or what came to be known as a style, of an ancient trait, and successively younger cultural manifestations would have progressively lower percentages of that variant. The principle of overlapping permitted building sequences of fossils and artifacts, but differences in the units that allowed the chronometers to be operationalized reveal significant epistemological variation in how historical research is undertaken. This variation should be of considerable interest to paleobiologists and archaeologists alike, especially given recent archaeological interest in creating and explaining historical lineages of artifacts
