ECONOMIC IMPACTS RESULTING FROM CO-FIRING BIOMASS FEEDSTOCKS IN SOUTHEASTERN UNITED STATES COAL-FIRED PLANTS

Economic impacts of using biomass in Southeast United States coal-fired plants are estimated using a county-level biomass database; ORCED, a dynamic electricity distribution model that estimates feedstock value; ORIBAS, a GIS model that estimates feedstock transportation costs; and IMPLAN, an input-output model that determines the impacts of co-firing on economic activity.Resource /Energy Economics and Policy,

Where do we go from here? An assessment of navigation performance using a compass versus a GPS unit

The Global Positioning System (GPS) looks set to replace the traditional map and compass for navigation tasks in military and civil domains. However, we may ask whether GPS has a real performance advantage over traditional methods. We present an exploratory study using a waypoint plotting task to compare the standard magnetic compass against a military GPS unit, for both expert and non-expert navigators. Whilst performance times were generally longer in setting up the GPS unit, once navigation was underway the GPS was more efficient than the compass. For mediumto long-term missions, this means that GPS could offer significant performance benefits, although the compass remains superior for shorter missions. Notwithstanding the performance times, significantly more errors, and more serious errors, occurred when using the compass. Overall, then, the GPS offers some clear advantages, especially for non-expert users. Nonetheless, concerns over the development of cognitive maps remain when using GPS technologies

A new species of the fish louse genus Dipteropeltis Calman, 1912 (Crustacea: Branchiura) from Peru

Dipteropeltis es un género poco descrito de piojo de los peces endémico de Sudamérica. En una pequeña región de aguas negras en Loreto, Perú, se observaron y recolectaron 13 especímenes adultos y juveniles de una especie no identificada de Dipteropeltis Calman, 1912, así como un espécimen adulto de D. hirundo Calman, 1912. Se adquirieron micrografías electrónicas y ópticas de barrido para examinar y medir características clave de estos especímenes. Las diferencias morfológicas con las dos especies conocidas de Dipteropeltis, D. hirundo y D. Dipteropeltis Neethling et al., 2014, indican que los especímenes recogidos representan una nueva especie. Dipteropeltis longicaudatus sp. nov. se distingue por sus lóbulos abdominales alargados, un caparazón en forma de cresta y unos maxilares de forma única. Un espécimen representa el branquiuro más largo documentado hasta la fecha, con 31,5 mm. Además, se proporcionan los primeros datos de secuencia para este género utilizando códigos de barras de ADN, lo que corrobora la designación de una nueva especie. También se grabaron vídeos que documentan comportamientos como la fijación al hospedero, la pulsación de los lóbulos abdominales, el "desplazamiento" del disco de succión y la natación. Los hallazgos tienen implicaciones para sus hospederos teleósteos, Triportheus albus Cope, 1872 y Brycon amazonicus Spix & Agassiz, 1829, siendo este último una especie crítica para la acuicultura y la pesca comercial en la Amazonia.Revisión por pares

Multiple Method Contraception Use among African American Adolescents in Four US Cities

We report on African American adolescents' (N = 850; M age = 15.4) contraceptive practices and type of contraception utilized during their last sexual encounter. Respondents completed measures of demographics, contraceptive use, sexual partner type, and ability to select “safe” sexual partners. 40% endorsed use of dual or multiple contraceptive methods; a total of 35 different contraceptive combinations were reported. Perceived ability to select “safe” partners was associated with not using contraception (OR = 1.25), using less effective contraceptive methods (OR = 1.23), or hormonal birth control (OR = 1.50). Female gender predicted hormonal birth control use (OR = 2.33), use of less effective contraceptive methods (e.g., withdrawal; OR = 2.47), and using no contraception (OR = 2.37). Respondents' age and partner type did not predict contraception use. Adolescents used contraceptive methods with limited ability to prevent both unintended pregnancies and STD/HIV. Adolescents who believed their partners posed low risk were more likely to use contraceptive practices other than condoms or no contraception. Reproductive health practitioners are encouraged to help youth negotiate contraceptive use with partners, regardless of the partner's perceived riskiness
