IT\u27S HARD TO BE DOWN WHEN YOU\u27RE UP. by Katherine March Driscoll BFA, Photography, NYSCC School of Art and Design at Alfred University, 2008 MFA, Imaging Arts, Rochester Institute of Technology, 2013 In times of transition, the American dream must be evaluated in terms of a possible future rather than an impossible past. It\u27s hard to be down when you\u27re up pictures Rochester, NY as a model for the transition- al state of today\u27s American cities using the color documentary style of 70\u27s photographers like Stephen Shore. Photographs and installation cite the fragments of potential found within the urban landscape through the dialectical nature of walking and reflecting, examining the relation- ships between person and place, reality and fantasy, history and future

Bystander empowerment amongst trained facilitators of the Mentors in Violence Prevention (MVP) program : an exploratory study

This study explores how a sample of college students trained to be peer facilitators of the Mentors in Violence Prevention (MVP) program describe the impact of their training. Participants (N=7) were undergraduates from a medium size New England University who attended an MVP Train the Trainer program, which consisted of 25-30 hours of training on facilitation skills and exposure to the MVP curriculum. Participants of this study were asked open-ended questions on the messages of the MVP program, their concept of being an empowered bystander, their use of training, and ways they identify themselves as more empowered bystanders. The findings indicate that participants\u27 concepts of an empowered bystander and the messages they gleaned from the program were consistent with the MVP curriculum. A major finding was that after being trained, most participants did not go onto facilitate MVP programs. However, participants provided a range of examples of how they have used their training in everyday situations indicative of their behavior as bystanders post-training. Findings having to do with the diversity amongst trainees that attended the Train the Trainer are also presented. Discussion highlights the multiple benefits of the training and explores the problematic issue of facilitators not having programming opportunities. Discussion also suggests that social workers in a university or community setting may find value in offering the MVP program or other bystander approach prevention programs for the purpose of augmenting clinical services and as a measure of primary prevention of sexual violenc

Pseudogap metal induced by long-range Coulomb interactions

In correlated electron systems the metallic character of a material can be strongly suppressed near an integer concentration of conduction electrons as Coulomb interactions forbid the double occupancy of local atomic orbitals. While the Mott-Hubbard physics arising from such on-site interactions has been largely studied, several unexplained phenomena observed in correlated materials challenge this description and call for the development of new ideas. Here we explore a general route for obtaining correlated behavior that is decidedly different from the Mott-Hubbard mechanism and instead relies on the presence of unscreened, long-range Coulomb interactions. We find a previously unreported pseudogap metal phase characterized by a divergent quasiparticle mass and the opening of a Coulomb pseudogap in the electronic spectrum. The destruction of the Fermi liquid state occurs because the electrons move in a nearly frozen, disordered charge background, as collective charge rearrangements are drastically slowed down by the frustrating nature of long-range potentials on discrete lattices. The present pseudogap metal realizes an early conjecture by Efros, that a soft Coulomb gap should appear for quantum lattice electrons with strong unscreened interactions due to self-generated randomness.Comment: 4 pages + 3 pages supplementary informatio

Development of a Glucose-Free Cell Culture Media for Primary Colonocytes

Development of lab on a chip technology, specifically for the colon, has great potential to elucidate mechanisms for chronic illness as well as to serve as a screening study for colonic drugs and causes for infection. For this technology to be representative of the colon, the environment to which colonocyte cells are exposed must be similar to in-vivo conditions. Thus, glucose must not be present in solution, as it is not naturally found in the lumen of the colon. This study focused on the development of a glucose-free cell culture medium.Bachelor of Scienc

Impact of Climate Change on Hydrochemical Processes at Two High-Elevation Forested Watersheds in the Southern Appalachians, United States

Climate change increasingly affects primary productivity and biogeochemical cycles in forest ecosystems at local and global scales. To predict change in vegetation, soil, and hydrologic processes, we applied an integrated biogeochemical model Photosynthesis-EvapoTranspration and BioGeoChemistry (PnET-BGC) to two high-elevation forested watersheds in the southern Appalachians in the US under representative (or radiative) concentration pathway (RCP)4.5 and RCP8.5 scenarios. We investigated seasonal variability of the changes from current (1986–2015) to future climate scenarios (2071–2100) for important biogeochemical processes/states; identified change points for biogeochemical variables from 1931 to 2100 that indicate potential regime shifts; and compared the climate change impacts of a lower-elevation watershed (WS18) with a higher-elevation watershed (WS27) at the Coweeta Hydrologic Laboratory, North Carolina, United States. We find that gross primary productivity (GPP), net primary productivity (NPP), transpiration, nitrogen mineralization, and streamflow are projected to increase, while soil base saturation, and base cation concentration and ANC of streamwater are projected to decrease at the annual scale but with strong seasonal variability under a changing climate, showing the general trend of acidification of soil and streamwater despite an increase in primary productivity. The predicted changes show distinct contrasts between lower and higher elevations. Climate change is predicted to have larger impact on soil processes at the lower elevation watershed and on vegetation processes at the higher elevation watershed. We also detect five change points of the first principal component of 17 key biogeochemical variables simulated with PnET-BGC between 1931 and 2100, with the last change point projected to occur 20 years earlier under RCP8.5 (2059 at WS18 and WS27) than under RCP4.5 (2079 at WS18 and 2074 at WS27) at both watersheds. The change points occurred earlier at WS18 than at WS27 in the 1980s and 2010s but in the future are projected to occur earlier in WS27 (2074) than WS18 (2079) under RCP4.5, implying that changes in biogeochemical cycles in vegetation, soil, and streams may be accelerating at higher-elevation WS27

Specimen collection for the diagnosis of pediatric pneumonia.

Diagnosing the etiologic agent of pneumonia has an essential role in ensuring the most appropriate and effective therapy for individual patients and is critical to guiding the development of treatment and prevention strategies. However, establishing the etiology of pneumonia remains challenging because of the relative inaccessibility of the infected tissue and the difficulty in obtaining samples without contamination by upper respiratory tract secretions. Here, we review the published and unpublished literature on various specimens available for the diagnosis of pediatric pneumonia. We discuss the advantages and limitations of each specimen, and discuss the rationale for the specimens to be collected for the Pneumonia Etiology Research for Child Health study

Five planets and an independent confirmation of HD 196885Ab from Lick Observatory

We present time series Doppler data from Lick Observatory that reveal the presence of long-period planetary companions orbiting nearby stars. The typical eccentricity of these massive planets are greater than the mean eccentricity of known exoplanets. HD30562b has Msini = 1.29 Mjup, with semi-major axis of 2.3 AU and eccentricity 0.76. The host star has a spectral type F8V and is metal rich. HD86264b has Msini = 7.0 Mjup, arel = 2.86 AU, an eccentricity, e = 0.7 and orbits a metal-rich, F7V star. HD87883b has Msini = 1.78 Mjup, arel = 3.6 AU, e = 0.53 and orbits a metal-rich K0V star. HD89307b has Msini = 1.78 Mjup, arel = 3.3 AU, e = 0.24 and orbits a G0V star with slightly subsolar metallicity. HD148427b has Msini = 0.96 Mjup, arel = 0.93 AU, eccentricity of 0.16 and orbits a metal rich K0 subgiant. We also present velocities for a planet orbiting the F8V metal-rich binary star, HD196885A. The planet has Msini = 2.58 Mjup, arel = 2.37 AU, and orbital eccentricity of 0.48, in agreement with the independent discovery by Correia et al. 2008.Comment: 12 figures, 8 tables, accepted Ap
