Introduction Post: John Hill

My first two weeks have been busy and exciting. I have trained with several reference librarians during my shifts at the Reference Desk. Each of them has a different perspective on librarianship, and each of them plays a different role in Musselman Library, but all of them are devoted to making useful resources available to students and faculty and to teaching them how to use these resources. I am excited to practice strategies for answering people’s questions, but I am admittedly nervous to staff the desk on my own. I am confident, though, that with a little bit more time and experience, I’ll be okay. [excerpt

Instruction and Focus Groups

My internship focuses not only on reference librarianship, but also information literacy and instruction. Accordingly, I’ve been fortunate to sit in on some library instruction classes with Clint. I think that the image of a librarian as a reference resource is pretty well established in our cultural consciousness, at least here at Gettysburg College, but the image of librarian as teacher is perhaps not as prominent. At some colleges and universities, however, librarians are considered part of the faculty. [excerpt

Final Post

It’s hard to believe that my last semester at Gettysburg College is almost over. My senior year has gone by so quickly! Yesterday, I helped with the Finals Study Break. We served almost 12 gallons on ice cream to students working in the library. I also managed to win my first game of Uno with Clint, Mallory, Meghan, and Chelsea. I have learned so much from my internship. Our library is a complex organism with various moving parts, and it takes coordination and hard work to keep things running. I am glad that I was about to focus on one aspect of librarianship to see how it connects with the other parts of the library. [excerpt

Open-Access and The Cupola

I am currently working to develop The Cupola, Gettysburg College’s open-access compliant institutional repository. That’s a mouthful! What, exactly, is an open-access compliant institutional repository? Since I’m a philosophy student at heart, I’ll engage in a little bit of conceptual analysis and explain what each of these constituent terms mean. An institutional repository is a place where an institution—in this case, Gettysburg College—can store and preserving the research created by its members. The Cupola stores research by faculty, but also students. [excerpt

T-Parity Violation by Anomalies

Little Higgs theories often rely on an internal parity ("T-parity'') to suppress non-standard electroweak effects or to provide a dark matter candidate. We show that such a symmetry is generally broken by anomalies, as described by the Wess-Zumino-Witten term. We study a simple SU(3) x SU(3)/SU(3) Little Higgs scheme where we obtain a minimal form for the topological interactions of a single Higgs field. The results apply to more general models, including [SU(3) x SU(3)/SU(3)]^4, SU(5)/SO(5), and SU(6)/Sp(6).Comment: 17 page

Data analysis for Skylab proton spectrometer

The measured values are compared to values derived from a proton environment model. Spectral data are compared, the omni-directional fluxes are found, a range of assumed pitch angle distributions are established, and the values which would be seen by an idealized proton spectrometer immersed in the model environment are computed. The measured values and calculated values are summed over time, then ratiod to provide spectral correction factors. The data are tabulated according to location, pitch angle, energy, assumed pitch angle distribution, and orientation in the earth-fixed coordinate system. With the aid of this data, detailed corrections to the proton model environment are derived. Best-fit, energy-dependent pitch angle distributions are also obtained. Some information is derived concerning the east-west asymmetry

A theoretical approach for analyzing the restabilization of wakes

Recently reported experimental results demonstrate that restabilization of the low-Reynolds-number flow past a circular cylinder can be achieved by the placement of a smaller cylinder in the wake of the first at particular locations. Traditional numerical procedures for modeling such phenomena are computationally expensive. An approach is presented here in which the properties of the adjoint solutions to the linearized equations of motion are exploited to map quickly the best positions for the small cylinder's placement. Comparisons with experiment and previous computations are favorable. The approach is shown to be applicable to general flows, illustrating how strongly control mechanisms that involve sources of momentum couple to unstable (or stable) modes of the system
