George Croll Baum: Building A Greater Gettysburg

On November 16th, 1926 George Croll Baum died. In Gettysburg, Pennsylvania the local newspaper covered his death. The Gettysburgian, the paper for Gettysburg College reported that Henry W.A. Hanson, the college president, was “deeply distressed and further noted that Baum\u27s death \u27touched the hearts of all that knew him with deep regret.\u27 Within a month Dr. Hanson had already ordered three memorial plaques to be placed on the campus. Baum\u27s family tried to help pay for them. Hanson refused the money. In a correspondence with Baum‟s brother about the plaques, Hanson told him, “What I did for your brother George was a service of love to him.” One of these plaques was placed in the main entrance to the Gettysburg College Eddie Plank Memorial Gym, where it remains today. But who was George Baum, this man whose death greatly affected Gettysburg College? If one were to search the Appendices of Charles Glatfelter‟s seminal history of Gettysburg College, among the list of faculty and trustees one will find no reference to George Baum, although three other Baums--George‟s father, brother and nephew--are in the list of trustees. Baum was in fact the architect for Gettysburg College from 1914-1926, during a career which saw the construction of four major college buildings still standing today, as well as work on numerous smaller projects.

The Pierre Auger Observatory: Results on Ultra-High Energy Cosmic Rays

The focus of this article is on recent results on ultra-high energy cosmic rays obtained with the Pierre Auger Observatory. The world's largest instrument of this type and its performance are described. The observations presented here include the energy spectrum, the primary particle composition, limits on the fluxes of photons and neutrinos and a discussion of the anisotropic distribution of the arrival directions of the most energetic particles. Finally, plans for the construction of a Northern Auger Observatory in Colorado, USA, are discussed.Comment: Proceedings of the International Workshop on Advances in Cosmic Ray Science, Waseda University, Shinjuku, Tokyo, Japan, March 2008; to be published in the Journal of the Physical Society of Japan (JPSJ) supplemen

Description of Atmospheric Conditions at the Pierre Auger Observatory Using Meteorological Measurements and Models

Atmospheric conditions at the site of a cosmic ray observatory must be known well for reconstructing observed extensive air showers, especially when measured using the fluorescence technique. For the Pierre Auger Observatory, a sophisticated network of atmospheric monitoring devices has been conceived. Part of this monitoring was a weather balloon program to measure atmospheric state variables above the Observatory. To use the data in reconstructions of air showers, monthly models have been constructed. Scheduled balloon launches were abandoned and replaced with launches triggered by high-energetic air showers as part of a rapid monitoring system. Currently, the balloon launch program is halted and atmospheric data from numerical weather prediction models are used. A description of the balloon measurements, the monthly models as well as the data from the numerical weather prediction are presented

Search for photons at the Pierre Auger Observatory

The Pierre Auger Observatory has a unique potential to search for ultra-high energy photons (above ~1 EeV). First experimental limits on photons were obtained during construction of the southern part of the Observatory. Remarkably, already these limits have proven useful to falsify proposals about the origin of cosmic rays, and to perform fundamental physics by constraining Lorentz violation. A final discovery of photons at the upper end of the electromagnetic spectrum is likely to impact various branches of physics and astronomy.Comment: 5 pages, 5 figures.

On the Use of a Cash Flow Time-Series to Measure Property Performance

Modern portfolio theory is increasingly being used to guide real estate portfolio decisions. However, to obtain meaningful results from complex mathematical techniques, the input data must meet at least two conditions: property values must be measured accurately, and the process by which property valuations change over time must be known. Neither of these conditions are satisfied by data currently available. This paper closely examines how value is measured and reported for commercial property. Commonly used time-series from NREI, NCREIF and ACLI are found wanting. An index of value using the popular "repeat sales" method is derived using data from Freddie Mac's multifamily portfolio. The focus of this paper is on developing an alternative measure of property performance based on property net operating income. Two cash flow indices are constructed from publicly available data and evaluated. It is recommended that the methodology developed here be used to create cash flow indices that can supplement or replace existing value indices in property analysis. The cash flow indices have much to offer researchers applying option-based models to real estate.

The Hospital Costs of Firearm Assaults

In the wake of recent high profile incidents of gun violence, there is renewed national attention on the prevalence and cost of firearm assaults in the United States. To make informed policy decisions, lawmakers are calling for current and accurate data on the costs of these assaults. This brief examines the costs of emergency department (ED) visits and hospital admissions for firearm assault victims in the United States in 2010. These costs are further examined according to patient gender, age, median household income, and insurance status
