The Determinants of NFL Ticket Prices: What Managers May Consider when Pricing Tickets

Our purpose of this study is to determine what factors contribute to NFL ticket prices across teams and over time. After creating a theoretically sound model based on past economic studies, a panel data set was constructed based on the 32 NFL teams from the 2002 through the 2010 season. Results of this study show that a team’s previous season’s winning percentage, the average income of the area, the population of the area, and playing in a new stadium all have a positive, and significant, influence on ticket price. This study’s outcome allows fans and others to observe what team managers may consider when making price-changing decisions, and also by what percent a change in each factor will potentially change price. The study also shows what contributes to ticket price over time, an interesting observation given the rapid increase in the demand for football in the last decade

Ultimatum Bargaining by Children and Adults

Recent research on ultimatum bargaining, the fact that children often confront and use ultimatums, and theories of developmental psychology all combine to suggest that studying children's ultimatum behavior will be particularly enlightening, both theoretically and with respect to the development of bargaining behavior. The results from two experiments indicate that younger children made larger o?ers and accepted smaller o?ers than older participants. Boys took greater strategic advantage of asymmetric information than girls; this dichotomy began with nine-year-olds (third graders) and continued for twelve- and fifteen-year-olds (sixth and ninth graders) as well as for college students. Like adults, children accepted smaller o?ers when they did not know how much was being divided. Older children required increasingly higher o?ers, except for college students who were willing to accept considerably less than others. Also, some of the nine-year-olds displayed an extremely strong sense of fairness. The discussion focuses on the development of bargaining strategies and concerns for fairness.Adults, children, fairness, ultimatum bargaining

Modeling dynamically coupled fluid-duct systems with finite line elements

Structural analysis of piping systems, especially dynamic analysis, typically considers the duct structure and the contained fluid column separately. Coupling of these two systems, however, forms a new dynamic system with characteristics not necessarily described by the superposition of the two component system's characteristics. Methods for modeling the two coupled components simultaneously using finite line elements are presented. Techniques for general duct intersections, area or direction changes, long radius bends, hydraulic losses, and hydraulic impedances are discussed. An example problem and results involving time transients are presented. Additionally, a program to enhance post-processing of line element models is discussed

Platelet Response in Hypercholesterol Blood to Thrombin-Induced Aggression

A report submitted by David J. Saxon to the Research and Creative Productions Committee in 1989 on whether hypercholesterol platelets are more responsive than normocholesterolemic platelets to thrombin-induced aggregation in whole blood

Test Analysis Correlation of the Single Stringer Bending Tests for the Space Shuttle ET-137 Intertank Stringer Crack Investigation

On November 5, 2010, Space Shuttle mission STS-133 was scrubbed due to a hydrogen leak at the Ground Umbilical Carrier Plate (GUCP). After the scrub, a crack in the foam thermal protection system (TPS) was observed on the External Tank (ET) near the interface between the liquid oxygen (LOX) tank and the Intertank. When the damaged foam was removed, two 9-in. long cracks were found on the feet of Intertank stringer S7-2, and the stringer failure was the cause of the TPS crack. An investigation was conducted to determine the root cause of the cracks, establish a remedy/repair for the stringers, and provide flight rationale for the damaged tank, ET-137. The Space Transportation System (STS) Super Lightweight ET (SLWT) is comprised of two propellant tanks (an aft liquid hydrogen (LH2) tank and a forward LOX tank) and an Intertank. The Intertank serves as the structural connection between the two propellant tanks and also functions to receive and distribute all thrust loads from the solid rocket boosters . The Intertank is a stiffened cylinder structure consisting of eight mechanically joined panels (two integrally-stiffened, machined thrust panels to react the booster loads and six stringer-stiffened skin panels). There are one main ring frame, four intermediate ring frames, and forward and aft flange chords that mate to the respective propellant tanks.. The skin/stringer panels utilize external hat-section stringers that are mechanically attached with rivets along most of their length and with specialty fasteners, such as GP Lockbolts and Hi-Loks, at the forward and aft ends where the stringers attach to the flange chords. During the STS-133 Intertank stringer crack investigation, cracks were found on a total of five stringers. All of the cracks were at the LOX end, in the feet of the stringers, and near the forward fasteners (GP Lockbolts). Video of tanking for the November 5 launch attempt was used to determine that the TPS failure, and thus the stringer failure, occurred as the LOX liquid level crossed the LOX tank / Intertank interface ring frame. Hence, cryogenically-induced displacements were suspected as a contributing cause of the stringer cracks. To study the behavior of Intertank stringers subjected to similar displacements, static load tests of individual stringers, colloquially known as "single stringer bending tests" were performed. Approximately thirty stringers were tested, many of which were cut from the partially completed Intertank for what would have been ET-139. In addition to the tests, finite element (FE) analyses of the test configuration were also performed. In this paper, the FE analyses and test-analysis correlation for stringer test S6-8 are presented. Stringer S6-8 is a "short chord" configuration with no doubler panels
