A Study of the Regional Endogenous Development through Rural-Urban Circulation

En tres breves capítulos, el artículo pone a disposición las ideas básicas que cruzan la reflexión sobre las actividades económicas que las personas realizan en condiciones de pobreza, destacándose la preocupación sobre si estos desempeños pueden constituirse en alternativas de crecimiento económico a nivel local o si ellas son actores que inciden en las políticas públicas que organizan los supuestos del desarrollo.Palabras clave Actividades Económicas Autogestionadas / Autonomía / Capacitación / Desarrollo Endógeno.Abstract:In three brief chapters, the article displays the basic ideas that intersect the reflection on the economic activities that people perform in conditions of poverty, standing out the concern whether these performances can constitute in alternatives of economic growth at the local level or whether they are activities that affect the public policies which organize the theories of development.Key words Self-managed economic activities / Autonomy / Training / Endogenous Development

Endogenous Development

This study was designed to elucidate the early endogenous development of Sarcocystis rauschorum (Apicomplexa: Sarcocystidae) in varying lemmings, Dicrostonyx richardsoni. After determining the dose–response effects of sporocysts of S. rauschorum on lemmings (doses greater than 500 sporocysts were lethal during hepatic merogony), sporocysts were administered to additional lemmings that were killed beginning 1 day postinoculation (DPI) and continuing to 15.0 DPI. Merogony of S. rauschorum occurs in hepatocytes 4 – 6 DPI; merozoites were also found in leucocytes 5 – 6 DPI in liver impression smears. Cyst formation began 9.0 DPI in striated muscle (rarely in cardiac muscle) and only metrocytes were present to 15.0 DPI. Overall, S. rauschorum has only one precystic generation of merogony, in hepatocytes, and then rapidly forms cysts containing metrocytes in striated musculature.
