Empirical research on the chronic pain experience of older African Americans is scarce. Here, the authors examined the influence psychosocial indicators have on the pain experience in a sample of older African Americans. Data were collected from African Americans (N = 247) 50 to 96 years of age (69.4 ± 9.4). All participants provided self-report data on pain indicators, demographic characteristics, social (social support, locus of control, life satisfaction) variables, and depression. Those reporting higher levels of social support and depressive symptoms experienced greater pain intensity. Pain had an indirect effect on depression as mediated through life satisfaction. These findings demonstrate the need to focus more on the means to prevent and treat pain and to ameliorate its impact on social well-being, psychological functioning, and quality of life in older adults in general and older minority adults in particular. © The Author(s) 2011.

This essay studies Edie Fake's award-winning graphic novel Gaylord Phoenix from the perspective of Queer Theory and Transgender Studies. Nikki Sullivan's use of the term transmogrification from her work on somatechnics provides a critical lens through which to examine Fake's exploration of the transgender body in his narrative. Fake includes multiple images of bodies undergoing radical transformations through a combination of magic and surgery, blurring the distinction between modern science and the occult. The essay also explores Fake's status as an innovator in the world of comic books and graphic novels as he creates an idiosyncratic verbal and visual vocabulary largely unprecedented in the world of sequential art. © 2013 Springer Science+Business Media New York.

Three chemical educators, working with others in a large metropolitan area, have followed a trajectory whereby they built a multi-faceted program of chemical education practice. This followed a trajectory of development that was done in part through three particular projects, one focused on course development, one on lab materials development, and a third on curriculum development. The three projects are described according to common themes that played out in very different ways: collaboration, interdisciplinarity, student-focus, and dissemination. But attending to these themes, long term development of sustainable programs occurred, with impacts at the individual, institutional, regional, and national levels. © 2013 American Chemical Society.

• Premise of the study: New World Bambusoideae have only recently been studied in a phylogenomic context. Plastome sequences were determined and analyzed from Arundinaria appalachiana, A. tecta, and Olyra latifolia, to refine our knowledge of their evolution and historical biogeography. A correction is noted regarding an error in an earlier report on the biogeography of Cryptochloa. • Methods: Single-end DNA libraries were prepared and sequenced on the Illumina platform. Complete plastomes were assembled and analyzed with 13 other Poaceae.• Key results: Complete sampling in Arundinaria and an additional species of Olyreae gave a more detailed picture of their evolution/historical biogeography. Phylogenomic analyses indicated that the first major divergence in Arundinaria occurred around 2.3 to 3.2 mya and that Arundinaria tecta and A. appalachiana diverged from their common ancestor around 0.57 to 0.82 mya. Estimates of the divergence of Olyra latifolia from Cryptochloa strictiflora ranged from 14.6 to 20.7 mya. The age of the stem node of Olyreae ranged from an estimated 26.9 to 38.2 mya. • Conclusions: Estimates of divergences in Arundinaria can be correlated with paleoclimatic events including an early Pliocene warming, subsequent cooling, and North American glaciations. Discriminating between alternate evolutionary/biogeographic scenarios in Olyreae is challenging. © 2014 Botanical Society of America. Source

The spirocyclic oxazinoquinolinespirohexadienone (OSHD) "photochromes" are computationally predicted to be an attractive target as electron deficient analogues of the perimidinespirohexadienone (PSHD) photochromes, for eventual application as photochromic photooxidants. We have found the literature method for their preparation unsuitable and present an alternative synthesis. Unfortunately the product of this synthesis is the long wavelength (LW) ring-opened quinonimine isomer of the OSHD. We have found this isomer does not close to the spirocyclic short wavelength isomer (SW) upon prolonged standing in the dark, unlike other PSHD photochromes. The structure of this long wavelength isomer was found by NMR and X-ray crystallography to be exclusively the quinolinone (keto) tautomer, though experimental cyclic voltammetry supported by our computational methodology indicates that the quinolinol (enol) tautomer (not detected by other means) may be accessible through a fast equilibrium lying far toward the keto tautomer. Computations also support the relative stability order of keto LW over enol LW over SW. © 2012 American Chemical Society. Source
