Assessing History Student Research Activity and Learning Outcomes Through the Understanding Library Impacts Project
Get PDFIn an era when academic libraries increasingly need to justify their budgets and impact to campus administrators, there is a growing necessity for helpful assessment tools. Engaging in this current trend of “demonstrating value,” this liberal arts college sought to explore areas of impact through a focused study on one particular department with known high library activity. For the past two years the library and the history department have partnered with an outside project called Understanding Library Impacts. Beginning with a beta-test of a quantitative and qualitative survey tool in upper-level courses and later expanding to history courses at all levels, the project sought to measure library activity for research projects in these courses and connect this activity to student learning outcomes. The data informed us about student usage of “traditional” and electronic library resources, as well as discovery tools, facilities and services. Through it, students highlighted their “most valued” resources and described the benefits and problems they encountered there. Open-ended questions explored student-identified learning objectives and methods for overcoming research challenges. The survey also explored various means of mapping this activity onto broader learning outcomes at the departmental and institutional level. This poster will share what the library learned from this collaborative process and highlight one way that libraries can link their assessment data with departmental and institutional learning goals
The Anchor, Volume 127.12: November 27, 2013
Get PDFThe Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor\u27s history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). In recent years The Anchor moved to monthly print issues and a more frequently updated website. The Anchor is now published in print twice per academic semester. Occasionally, the volume and/or issue numbering is irregular

SuN: Summing NaI(Tl) gamma-ray detector for capture reaction measurements
No full textHigh demand for nuclear reaction cross-section measurements relevant for astrophysical processes requires the development of new experimental techniques that allow for investigation of, often very low, cross-sections. For this purpose, a new 4 pi Summing Nal(Tl) detector (SuN) has been constructed, which is an 8-fold segmented Nal(Tl) barrel read by 24 photomultipliers. The design of the detector will be presented and detailed results of the commissioning experiments utilizing standard calibration sources and known Al-27(p,gamma)Si-28 resonances will be discussed.

Imaging the Anisotropic Nonlinear Meissner Effect in Nodal YBa2Cu3O7-δ Thin-Film Superconductors
No full textWe have directly imaged the anisotropic nonlinear Meissner effect in an unconventional superconductor through the nonlinear electrodynamic response of both (bulk) gap nodes and (surface) Andreev bound states. A superconducting thin film is patterned into a compact self-resonant spiral structure, excited near resonance in the radio-frequency range, and scanned with a focused laser beam perturbation. At low temperatures, direction-dependent nonlinearities in the reactive and resistive properties of the resonator create photoresponse that maps out the directions of nodes, or of bound states associated with these nodes, on the Fermi surface of the superconductor. The method is demonstrated on the nodal superconductor YBa2Cu3O7-δ and the results are consistent with theoretical predictions for the bulk and surface contributions
Indocyanine Dyes Approach Free Rotation at the 3′ Terminus of A-RNA: A Comparison with the 5′ Terminus and Consequences for Fluorescence Resonance Energy Transfer
No full textCyanine dyes are widely used to study the folding and structural transformations of nucleic acids using fluorescence resonance energy transfer (FRET). The extent to which FRET can be used to extract inter- and intramolecular distances has been the subject of considerable debate in the literature; the contribution of dye and linker dynamics to the observed FRET signal is particularly troublesome. We used molecular dynamics (MD) simulations to study the dynamics of the indocarbocyanine dyes Cy3 and Cy5 attached variously to the 3\u27 or 5\u27 terminal bases of a 16-base-pair RNA duplex. We then used Monte Carlo modeling of dye photophysics to predict the results of single-molecule-sensitive FRET measurements of these same molecules. Our results show that the average value of FRET depends on both the terminal base and the linker position. In particular, 3\u27 attached dyes typically explore a wide region of configuration space, and the relative orientation factor, kappa(2), has a distribution that approaches that of free-rotators. This is in contrast to 5\u27 attached dyes, which spend a significant fraction of their time in one or more configurations that are effectively stacked on the ends of the RNA duplex. The presence of distinct dye configurations for 5\u27 attached dyes is consistent with observations, made by others, of multiple fluorescence lifetimes of Cy3 on nucleic acids. Although FRET is frequently used as a molecular ruler to measure intramolecular distances, the unambiguous measurement of distances typically relies on the assumption that the rotational degrees of freedom of the dyes can be averaged out and that the donor lifetime in the absence of the acceptor is a constant. We demonstrate that even for the relatively free 3\u27 attached dyes, the correlation time of kappa(2) is still too long to justify the use of a free-rotation approximation. We further explore the consequences of multiple donor lifetimes on the predicted value of FRET
Hope Comes to Watts: An Educational May Term Experience in Los Angeles
Get PDFThe Hope Comes to Watts program is designed to provide a 3-week May Term experience in Los Angeles, California. Students study the cultural, historical and geographical setting as well as complete pertinent readings to prepare for full-day placements in the Watts Learning Center, a public, charter school setting with elementary and middle school campuses. The Hope College students are paired one-on-one with classroom teachers and/or administrators and are fully immersed the day-to-day life of the school. They also participate in a variety of cultural and service opportunities during this experience
