"Jazz is Back": Alternative Jazz Venues and Gentrification in Washington, D.C.

Gentrification has dramatically changed the urban landscape of Washington, D.C. Non-profit alternative jazz venues have become important sites for negotiating this complex process that is re-shaping the city. Each such venue aligns itself with one of the two primary factions of gentrification: new urban migrants or long-term residents. Westminster Presbyterian Church’s Jazz Night in Southwest fosters a community of repeat-attendees resisting social displacement. The Jazz and Cultural Society unabashedly foregrounds ties to long-term residents in highlighting a black identity and its local interconnectedness. CapitolBop’s Jazz Loft demonstrates the difficulties that come with trying to cater to a young audience, and at the same time, resist gentrification. These venues present three perspectives on gentrification and together bring light to the overlapping complexity of gentrification.

PHYTOPLANKTON AND NUTRIENT DYNAMICS WITH A FOCUS ON NITROGEN FORM IN THE ANACOSTIA RIVER, IN WASHINGTON, D.C. AND WEST LAKE, IN HANGZHOU, CHINA

Nutrient loading has been linked with severe water quality impairment, ranging from hypoxia to increased frequency of harmful algal blooms (HABs), loss of fisheries, and changes in biodiversity. Waters around the globe are experiencing deleterious effects of eutrophication; however, the relative amount of nitrogen (N) and phosphorus (P) reaching these waters is not changing proportionately, with high N loads increasingly enriched in chemically-reduced N forms. Research involving two urban freshwater and nutrient enriched systems, the Anacostia River, USA, a tributary of the Potomac River feeding into the Chesapeake Bay, and West Lake, Hangzhou, Zhejiang Province, China, was conducted to assess the response of phytoplankton communities to changing N-form and N/P-ratios. Field observations involving the characterization of ambient phytoplankton communities and N-forms, as well as experimental (nutrient enrichment) manipulations were used to understand shifts in phytoplankton community composition with increasing NH4+ loads. In both locations, a >2-fold increase in ambient NH4+:NO3- ratios was followed by a shift in the phytoplankton community, with diatoms giving way to chlorophytes and cyanobacteria. Enrichment experiments mirrored this, in that samples enriched with NH4+ lead to increased abundance of chlorophytes and cyanobacteria. This work shows that in both of these systems experiencing nutrient enrichment that NH4+ supports communities dominated by more chlorophytes and cyanobacteria than other phytoplankton groups.

Prevalencia de desordenes musculo-esqueléticos y su asociación con factores ergonómicos en trabajadores administrativos de una institución educativa de nivel superior 2015

Objetivo. Establecer la prevalencia de Desordenes Musculo Esqueléticos(DME) y su asociación con factores ergonómicos (postura, manipulación de carga y trabajo repetitivo) en trabajadores administrativos de una Institución Educativa de Nivel Superior (IENS). Métodos. Se realizó un estudio descriptivo de corte transversal a 146 trabajadores de una IENS de la ciudad de Neiva (Huila), entre Abril y Mayo de 2015. Para la recolección de la información se utilizaron dos instrumentos: un instrumento para la caracterización sociodemográfica y ocupacional y el cuestionario estandarizado para identificar daños y exposición a riesgos ergonómicos en el trabajo (ERGOPAR). Resultados. El 90,4 % de los trabajadores presentaron molestia o dolor en alguna de las áreas del cuerpo, dentro de las cuales las más afectadas fueron las zonas del Cuello, hombros y/o espalda dorsal con el 79,9%, la espalda lumbar con el 65,8% y las manos y/o muñecas con el 49,3%. Conclusiones. Se encontró una asociación entre la exposición a factores ergonómicos y la presencia de DME, indicando que las posturas de trabajo forzadas o prolongadas y la manipulación de cargas representan un alto riesgo biomecánica para los trabajadores, lo cual se puede ver reflejado a mediano o largo plazo con el desarrollo de trastornos o enfermedades que pueden llegar a ser incapacitantes para los trabajadores, afectando su calidad de vida y su productividad laboral.
