The James David Ross Family Recreation Center opened its doors to the Washington & Jefferson College (W&J) community Friday, introducing a new facility to W&J students, staff, and faculty who will enjoy it for generations. “Athletics have always been an important part of W&J from the early days of cricket played on the lawn,” said W&J President Dr. Tori Haring-Smith. “More than 50 percent of incoming students participate in athletics their freshman year. The board recognized that to attract top students, we needed a facility that allowed them to train.” The Recreation Center is an addition to Henry Memorial Gymnasium, which has long been the home of athletics at W&J. The new 30,000-square foot facility features a three-lane, 167-meter walking/running track, three multi-sport athletic courts marked for basketball, volleyball, and tennis, a new wrestling room, and a general exercise room for activities like yoga and pilates. New offices and recruiting spaces for the Athletics Department are also included. The facility is open to W&J students, faculty, and staff only; Swanson Wellness Center will continue to house exercise equipment for use by the W&J community, and basketball and swimming events will still be held in Henry Memorial Gymnasium. The recreation center is named for the family of David A. Ross ’78, the project’s donor, who also led the construction process. Ross, a former member of the W&J Board of Trustees who serves as a non-trustee member of the Property, Building and Grounds Committee, is the founder of Atlantic Realty, one of largest privately owned real estate developers in the Washington, D.C. area. He has guided the construction and renovation of several W&J buildings, including Swanson Science Center, the renovation of Dieter-Porter Life Sciences Building, and Ross Memorial Park, also named for his family. The recreation center is a project of An Uncommon Bond: The Campaign for Washington & Jefferson College. The campaign has raised $114 million, and will continue through June 2017. Additional projects of the campaign include the construction of Janet Swanson Tennis Center, which opened on Sept. 11, 2015, and renovations to Dieter-Porter Life Sciences Building. Improvements to U. Grant Miller Library, among other initiatives, are planned. In addition to improvement projects, another goal of the campaign is to raise the College’s endowment by $60 million, and provide $10 million of unrestricted dollars. Endowment funds provide support in several areas, including: increasing financial aid to students; providing additional resources for faculty and students to travel for professional development, attend conferences and competitions, embark on extraordinary travel opportunities, or take on independent research projects around the world; and bring guest speakers to W&J for enlightening on-campus experiences. “I have no doubt the new recreation center will help us attract great athletes...but most importantly, it will give every student a place to work out, stay healthy, and stay active to call their own,” Ross said.

Washington & Jefferson College (W&J) will continue its Arbor Day tradition of environmental excellence. For the fourth consecutive year, W&J has been honored with the Tree Campus USA® recognition by the Arbor Day Foundation for its commitment to effective urban forest management. The college was one of only 15 institutions in Pennsylvania, a state with more than 100 two- and four-year higher learning institutions, to receive this honor, part of a national program created in 2008. Currently there are 296 campuses across the United States with this recognition. In addition to the Tree Campus USA honor, the arboretum was awarded Level I Accreditation by The ArbNet Arboretum Accreditation Program and The Morton Arboretum last spring. “I’m excited to have earned this recognition four years in a row and look forward to subsequent years of this recognition. This includes more plantings on campus, more students getting involved, more of the community getting involved and enhancing the campus arboretum and the campus landscape,” said Associate Professor of Biology Jason Kilgore, Ph.D. Kilgore noted that it’s become increasingly more difficult to qualify for the designation over the past few years as the Arbor Day Foundation has raised its standards when examining Tree Campus USA submissions. “It’s become more selective, which is good, because it forces us to work harder to be bigger and better than we were before,” he said. In honor of the recognition, students in Kilgore’s Plant Diversity course will plant Quaking Aspen trees at the developing Rocky Mountain-themed grove near the W&J Admission House at 1 p.m. April 29. Kilgore and Grounds Supervisor Doston Kish chose the trees to fit the soil profile in the area. It will be the first themed grove on campus, according to Kilgore. Washington & Jefferson College achieved the title by meeting Tree Campus USA’s five standards, which include maintaining a tree advisory committee, a campus tree-care plan, dedicated annual expenditures for its campus tree program, an Arbor Day observance, and a student service-learning project. W&J has been recognized every year it has applied for the honor. Kilgore started W&J’s Campus Arboretum nine years ago after previously being involved with Michigan State University’s arboretum. Working with students, he created two databases identifying types of trees on campus and their location, with notes of what trees have been added and removed from the grounds. The Campus Arboretum now encompasses the entire 85 acres of urban campus and athletic facilities. All of the nearly 1,200 trees from 83 species are recorded and evaluated, with over 930 trees bearing metal tags with accession number and family, scientific, and common names. Particularly noteworthy trees include a mature American elm, a mature willow oak, and five mature osage-oranges from an historical property line separating the College from the former Washington Female Seminary. The Arboretum Advisory Committee, consisting of members of the faculty, staff, and the community, meets twice a year to make decisions about the arboretum’s presence on campus and what progress will be made.

"The Chemistry of Perfume" is a lab-only course for nonscience majors. Students learn fundamental concepts of chemistry through the context of fragrance, a pervasive aspect of daily life. The course consists of laboratories pertaining to five units: introduction, extraction, synthesis, characterization, and application. The introduction unit acquaints students with basic perfume terminology and the idea that chemical structure relates to scent. The extraction unit focuses on capturing and isolating fragrant essences from natural materials, whereas the synthetic unit considers mimicking such scents through chemical reactions. In the characterization unit, students analyze the components of perfume and fragrant materials. The course ends with the application unit in which students incorporate their fragrances into consumer products and toiletries. Curriculum structure, content, and student feedback are described. This perfume lab course results from an effort to increase interest in chemistry among nonscience students and encourage interdisciplinary learning. © 2012 American Chemical Society and Division of Chemical Education, Inc.

The complete expression for the intensity in pseudo-scalar meson photoproduction with a polarized beam, target, and recoil baryon is derived using a density matrix approach that offers great economy of notation. A Cartesian basis with spins for all particles quantized along a single direction, the longitudinal beam direction, is used for consistency and clarity in interpretation. A single spin-quantization axis for all particles enables the amplitudes to be written in a manifestly covariant fashion with simple relations to those of the well-known Chew-Goldberger-Low-Nambu formalism. Possible sign discrepancies between theoretical amplitude-level expressions and experimentally measurable intensity profiles are dealt with carefully. Our motivation is to provide a coherent framework for coupled-channel partial-wave analysis of several meson photoproduction reactions, incorporating recently published and forthcoming polarization data from Jefferson Lab. © 2011 American Physical Society.

The 13C chemical-shift anisotropy in anthracene derivatives (9,10-dimethylanthracene, 9,10-dihydroanthracene, dianthracene, and triptycene) has been measured by the 2D FIREMAT timed pulse sequence and the corresponding set of principal values has been determined by the TIGER processing method. These molecules expand the data base of 13C CSA measurements of fused aromatic rings some bridged by sp3 carbon resulting in an unusual bonding configuration, which leads to distinctive aromatic 13C CSA values. Crystal lattice distortions to the CSA were observed to change the isotropic shift by 2.5 to 3.3 ppm and changes as large as 8.3 ppm in principal components. Modeling of the CSA data by GIPAW DFT (GGA-PBE/ultrafine) shielding calculations resulted in an rms chemical-shift distance of 2.8 ppm after lattice including geometry optimization of the diffraction structures by the GIPAW method at GGA-PBE/ultrafine level. Attention is given to the substituted aromatic carbon in the phenyl groups (here forth referred to as the α-carbon) with respect to CSA modeling with electronic methods. The 13C CSA of this position is accurately determined due to its spectral isolation of the isotropic shift that limits overlap in the FIREMAT spectrum. In cases where the bridging ring is sp3 carbon, the current density is reduced from extending beyond the peripheral phenyl groups; this plays a significant role in the magnetic shielding of the α-position. Nuclear independent chemical-shift calculations based on GIAO DFT (B3LYP/6-31G(d)) shielding calculations were used to model the intramolecular π-interactions in dianthracene and triptycene. These NICS results estimate the isotropic shift of the α-position in dianthracene to be insignificantly affected by the presence of the neighboring aromatic rings. However, a notable change in isotropic shielding, Δσiso=-2.1 ppm, is predicted for the α- position of triptycene. Experimentally, the δ22 principal component at the α-position for both dianthracene and triptycene increases by at least 12 ppm compared to 9,10-dihydroanthracene. To rationalize this change, shielding calculations in idealized structures are explored. The spatial position of the bicyclic scaffolding of the bridging ring plays a key role in the large increase in δ22 for the α-carbon. © 2013 Elsevier Inc. All rights reserved.

From simple models of thermally activated contact line dynamics far below the depinning transition, one expects the velocity to depend exponentially on the applied force and the activation area to be the size of the defects on the surface. We study contact line motion on evaporated gold films and find that the dynamics are activated, but the activation area is not straightforwardly linked to the surface roughness. Surprisingly, the activation area can be significantly smaller than any features on the surface. Furthermore, it depends strongly on the liquid. We show that this indicates that the line is close to the depinning threshold at experimentally accessible velocities. A model based on independent defects is developed and used to show deviations from the purely exponential law. The dynamics are written entirely in terms of properties of the surface and partially wetting liquid. In addition, we are able to show that the region of validity of models of thermal activation on mesoscopically rough surfaces typically corresponds to velocities of less than 1 mm/s. © 2013 American Chemical Society.

A solid-state crystal structure laboratory exercise for undergraduates in either a general chemistry course or a more advanced inorganic chemistry course is described. Students explore the lattice arrangement of atoms in unit cells by building models supplied by the Institute for Chemical Education. Emphasis is placed on building three-dimensional visual models of various crystal systems to display close packing of atoms, to identify tetrahedral and octahedral holes, to reveal number of atoms per unit cell, and to highlight ion coordination numbers and size differences. The relationship between solid-state bonding and a material's physical properties is emphasized for elemental carbon. © 2014 The American Chemical Society and Division of Chemical Education, Inc.

Polystyrene-block-poly(ethylene oxide) (PS-PEO) is an amphiphilic diblock copolymer that undergoes microphase separation when spread at the air/water interface, forming nanosized domains. In this study, we investigate the impact of PS by examining a series of PS-PEO samples containing constant PEO (∼17-000 g•mol -1) and variable PS (from 3600 to 200-000 g•mol -1) through isothermal characterization and atomic force microscopy (AFM). The polymers separated into two categories: predominantly hydrophobic and predominantly hydrophilic with a weight percent of PEO of ∼20% providing the boundary between the two. AFM results indicated that predominantly hydrophilic PS-PEO forms dots while more hydrophobic samples yield a mixture of dots and spaghetti with continent-like structures appearing at ∼7% PEO or less. These structures reflect a blend of polymer spreading, entanglement, and vitrification as the solvent evaporates. Changing the spreading concentration provides insight into this process with higher concentrations representing earlier kinetic stages and lower concentrations demonstrating later ones. Comparison of isothermal results and AFM analysis shows how polymer behavior at the air/water interface correlates with the observed nanostructures. Understanding the impact of polymer composition and spreading concentration is significant in leading to greater control over the nanostructures obtained through PS-PEO self-assembly and their eventual application as polymer templates. © 2012 American Chemical Society.

Title: MRI/Acq.: Acquisition of Eye Tracking System
Project Proposed:
This project from an undergraduate-serving institution, acquiring an Eye Tracking system, aims to add quantitative measures of changes in problem-solving techniques to more traditional outcomes-based assessments of student learning. The eye tracking system enables pursuing further work and greater quantitative analysis in design and usability research focused on issues such as the effect of the interface design of security-focused software on the secure behaviors and awareness of security features of the software users.
Current work at the institution focuses on the particular application of these methods in an introductory programming course. The Information Technology Leadership (ITL) faculty have broaden their research to encompass more mobile computing that has contributed in developing a collaboration with Biology faculty. In turn, this collaboration has given rise to a mobile application used when collecting ecological data in the field. A beta version, now under assessment, has been created and deployed where the eye tracking methods will be used to confirm that mobile technologies enable not only more accurate data collection, but better learning and retention on the part of the student researchers in the field.
Broader Impacts:
This solely undergraduate institution core mission focuses on research involving significant undergraduate collaboration. In particular, the ITL Department is committed to enabling its majors to take part in significant research projects that allow them to act as true collaborators and not simply as coders or lab technicians. Thus, with an existing history of engaging undergraduates in design and usability research, a modern eye tracking system will strengthen the program making it accessible to more students. The system will play a role in classroom activities, labs, and independent projects. Students should gain fluency with the tool and with appropriate methods for using it in regular coursework. A service management course will be required for all seniors to partner with local non-profits to provide technical consulting or development. The system provides a platform for continued interdisciplinary research, including ongoing work in Biology and potential projects that involve Political Science, Gender and Women?s Studies, Sociology, and Psychology.
