Abstract: the community structure of parasites on sciaena deliciosa (tschudi, 1846), is evaluated and eventual changes are analyzed in the composition, richness, diversity, prevalence and mean intensity of parasite communities on fish specimens that were similar in body length but were sampled 20 years apart (august 1987 to july 1988 vs. august to september 2008) in lima, perú. metazoan parasites were collected and counted employing conventional techniques. total abundance was 1.7 (0-13) and parasite species richness was 0.7 (0-2 parasite species per fish). thirsty hosts (60%) were infected by at least with one parasite. seven parasite taxa were found: two monogeneans (cynoscionicola sciaenae, hargicotyle sciaenae), a digenean (helicometra fasciata), a nematode (dycheline amaruincai), an acanthocephalan (tegorhynchus sp.), and two copepods (caligus callaoensis, lernanthropus huamani). this comparative analysis (parasites of s. deliciosa in 1987-1988 vs in 2008), showed a decreased prevalence of tegorhynchus sp., d. amaruincai, bomolochus peruensis, and neobrachiella oralis. the mean intensity increased for c americana and tegorhynchus sp. and diminished for c callaoensis. differences between years could be influenced by variations of sea temperature that affect larval stages and/or copepod reproduction over the course of the study period and size of the sample.

Abstract: Se evalúa la estructura comunitaria de los parásitos de Sciaena deliciosa (Tschudi, 1846), y se analiza si la composición, riqueza, diversidad, prevalencia e intensidad media de sus comunidades parasitarias cambia entre muestras tomadas con 20 a os de diferencia en Lima, Perú, entre agosto 1987 y julio 1988 y de agosto a septiembre del 2008 en peces de similar longitud corporal. Los parásitos metazoos fueron colectados y censados empleando las técnicas convencionales. La abundancia total fue de 1,7 (0 a 13) y la riqueza de especies de parásitos fue 0,7 (0 a 2 especies de parásitos por pez). Treinta hospederos mostraron infección con al menos un parásito (60%). Se encontraron siete taxa de parásitos: dos monogeneos Cynoscionicola sciaenae y Hargicotyle sciaenae; un digeneo Helicometra fasciata; un nemátodo Dycheline amaruincai, un acantocéfalo Tegorhynchus sp., y dos copépodos Caligus callaoensis y Lernanthropus huamani. Un análisis comparativo entre los parásitos de S. deliciosa entre 1987-1988 y 2008, muestran una disminución en la prevalencia de Tegorhynchus sp., D. amaruincai, Bomolochusperuensis y Neobrachiella oralis. La intensidad media aumentó para C. americana y Tegorhynchus sp. y disminuyó para C. callaoensis. Las diferencias entre a os pudieran estar influenciadas por las variaciones en la temperatura del agua que afectaron los estados larvales y/o reproducción de los copépodos, en la amplitud del periodo de estudio y en el tama o de la muestra.

Abstract: Objetivos. Estimar la prevalencia de sobrepeso, obesidad y los determinantes sociales del exceso de peso en po blación peruana. Materiales y métodos. Se realizó un estudio transversal que incluyó a los miembros residentes en los hogares de la muestra Encuesta Nacional de Hogares. Se empleó un muestreo probabilístico, estratificado y multietápico. La muestra incluyó 69 526 miembros; las mediciones antropométricas se realizaron según metodología internacional. Para evaluar el sobrepeso y obesidad se utilizó el peso para la talla (ni os <5 a os), IMC para la edad (ni os y adolescentes entre 5-19 a os) y el IMC para adultos. Se realizó el análisis para muestras complejas en SPSS y se ajustó por factor de ponderación. Se calculó estadísticas descriptivas y regresión logística con intervalo de confianza de 95%. Resultados. El sobrepeso y obesidad fue mayor en los adultos jóvenes (62,3%) y menor en los ni os <5 a os (8,2%). Los determinantes sociales del exceso de peso según el grupo de edad fueron: no ser pobre (ni o <5 a os, ni os 5-9 a os, adolescentes y adulto mayor), vivir en el área urbana (ni o<5 a os, adolescentes, adulto joven, adulto y adulto mayor) y ser mujer (ni os 5-9 a os, adulto y adulto mayor). Conclusiones. El sobrepeso y la obesidad constituyen un problema de salud pública en el Perú. No ser pobre y vivir en el área urbana son deter-minantes sociales del exceso de peso en población peruana. Objectives.

Introducing Engineering Students to Historical/Cultural Perspectives through Story-Centered On-Line Learning  [PDF]
Luis A Godoy
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.22009
Abstract: Several authors argued that history of science should be an integral part of science education; however, there are many obstacles to carry out an implementation within this approach, including that lecturers normally lack a necessary historical background (a situation that is largely aggravated in engineering faculties), and the impossi- bility of including new courses or credits in an already tight curriculum. The development of on-line modules that engineering students can work outside their normal schedule of classes, introducing historical/cultural per- spectives, is presented in this paper. E-learning and knowledge management strategies are used in the context of science education at undergraduate and graduate levels. The approach is based on learning-by-doing in a virtual environment, and specifically presents story-centered activities, in which the student is faced with a problem and plays the role of an expert to provide a solution to the case. The specific case considered develops in the form of a controversy concerning the origin of the studies of column buckling. Two sets of information are available for navigation in the module: specific information that the student can explore (containing historical material di- rectly connected to the case provided), and more general information (providing the historical/cultural context to the problem). A first application has been made with civil engineering students, who had to write a two-page white paper as a consequence of their work on the problem. The interest generated in the participating students and the positive evaluation of their experience seems to indicate that this type of activity can serve to enhance traditional engineering lectures by incorporating a historical dimension. The present web-based approach could be extended to tackle similar conflicts in fields for which there is ample documentation available in the literature or in other historical episodes which may lead to rich discussions.
