Cosmic Neutrinos and the Energy Budget of Galactic and Extragalactic Cosmic Rays
Although kilometer-scale neutrino detectors such as IceCube are discovery
instruments, their conceptual design is very much anchored to the observational
fact that Nature produces protons and photons with energies in excess of
10^{20} eV and 10^{13} eV, respectively. The puzzle of where and how Nature
accelerates the highest energy cosmic particles is unresolved almost a century
after their discovery. We will discuss how the cosmic ray connection sets the
scale of the anticipated cosmic neutrino fluxes. In this context, we discuss
the first results of the completed AMANDA detector and the science reach of its
extension, IceCube.Comment: 13 pages, Latex2e, 3 postscript figures included. Talk presented at

Cosmic Neutrinos from the Sources of Galactic and Extragalactic Cosmic Rays
Although kilometer-scale neutrino detectors such as IceCube are discovery
instruments, their conceptual design is very much anchored to the observational
fact that Nature produces protons and photons with energies in excess of 10^20
eV and 10^13 eV, respectively. The puzzle of where and how Nature accelerates
the highest energy cosmic particles is unresolved almost a century after their
discovery. From energetics considerations we anticipate order 10~100 neutrino
events per kilometer squared per year pointing back at the source(s) of both
galactic and extragalactic cosmic rays. In this context, we discuss the results
of the AMANDA and IceCube neutrino telescopes which will deliver a
kilometer-square-year of data over the next 3 years.Comment: 8 pages, 4 figure

Leadership Development for High School Students in a Summer Performing Arts Program
The purpose of this study was to evaluate a summer performing arts (SPA) program using elements of a servant leadership model to assess potential impacts of a SPA program on leadership skills development. High school students enrolled in a SPA program were given both a pre- and post-survey that included leadership questions. There was a growth in all five servant leadership factors with an overall standardized effect size of d = 0.48. The largest growth was for enabling others to take action through cooperation. Summer performing arts programs can positively impact student servant leadership abilities. The idea of youth leadership education may resonate with community business leaders when it comes to funding support for summer arts activities
