Graphic support resources for workers with intellectual disability engaged in office tasks: a comparison with verbal instructions from a work mate.

Background: Research into workplace adjustments for people with disabilities is a fundamental challenge of supported employment. The aim of the present work is to investigate the effect of several graphic resources as natural support for workers with intellectual disability.

Methods: Two case studies were conducted to assess the performance of five workers engaged in office tasks, with three different support conditions.

Feeding success of Lutzomyia evansi (Diptera: Psychodidae) experimentally exposed to small mammal hosts in an endemic focus of Leishmania chagasi in northern Colombia.

Lutzomyia evansi is the vector of Leishmania chagasi in northern Colombia. Differences in feeding success were revealed, when this phlebotomine sand fly was fed on five species of small mammal hosts from an endemic focus of visceral leishmaniasis. In each trial, 50 female sand flies were provided access to similar-sized depilated areas of the hind foot of each of 44 individual mammals and allowed to feed for 30 minutes.
