* The Use of Dyadic Reading in Stimulating the Comprehension of Emotions.
- According to the model proposed by Pons, Doudin, and Harris , children develop nine components of emotion comprehension between the ages of three to twelve. Studies reveal that children's comprehension of emotions can be stimulated by adults reading books designed for this purpose to preschool-aged children. The aim of this study is to explore whether dyadic reading is an effective strategy for stimulating emotion comprehension in school-aged children. Elementary school children (3rd, 4th and 5th grade) participated in the experimental or the control group. The Test of Emotion Comprehension (TEC) was administered at pretest and post-test. Participants in the experimental group read the books on emotion comprehension for five sessions, while participants in the control group read classroom books. Results revealed that reading the emotion comprehension books increased the TEC post-test scores significantly from pretest for children in the experimental group, compared to the control group. For the Components Reminder, Belief and Morality scores at post-test were significantly increased from pretest for children in the experimental group, compared to the control group. Results suggest that dyadic book readings are successful in helping children with both complex components of their emotion comprehension and simpler ones. This intervention could be of use for teaching school-aged children emotion comprehension easily, effectively, and at low-cost.
* Intestinal parasites in child and youth populations of Argentina: Environmental factors determining geographic distribution.
- The transmission of intestinal parasites is generally considered to be "mediated by the environment" which suggests that they are particularly sensitive to the changes that occur in it. The aim of the present study was to evaluate the environmental variables that act as risk factors for intestinal parasitosis in children and youths in Argentina. The association between environmental variables related to temperature, precipitation and soil and parasitosis found in children and youths from different provinces was evaluated, including land use/cover classes obtained from satellite images. Of the total population analyzed, 66.9% of the participants were parasitized. The total number of identified parasite species was 17 and the most prevalent were Blastocystis sp. (42.2%), Enterobius vermicularis (33.6%) and Giardia lamblia (17.0%). Infection by protozoa, and by G. lamblia in particular, was greater when the mean summer temperature was higher (OR=1.2 for both). Blastocystis sp. and geohelminths were greater due to an increase in isothermality (OR=1.1 and 1.2, respectively). The risk of infection with Ascaris lumbricoides was associated with an increase in the temperature in the wettest quarter (OR=1.2). Hookworm infection was associated with an increase in the normalized difference vegetation index (OR=32.5). Most of participants infected with hookworms lived in areas with abundant arboreal-shrubby and agropastoral use vegetation. The heterogeneous distribution of enteric parasites is indicative of the wide environmental variability of Argentina.
