RESUMO
Studies of food preferences in captive primates have so far mainly been restricted to frugivorous species. It was therefore the aim of the present study to assess the occurrence of spontaneous food preferences in a mainly folivorous primate, the captive Southern brown howler monkey, and to analyze whether these preferences correlate with nutrient composition. Using a two-alternative choice test, we presented ten male and five female adult Alouatta guariba clamitans with all possible binary combinations of ten types of food that are part of their diet in captivity and recorded their choice behavior. We found the howler monkeys to display the following rank order of preference: banana > mango > watermelon > papaya > beetroot > apple > pear > orange > cucumber > tomato. This preference ranking significantly and positively correlated with the total carbohydrate content and with the sucrose content of the food items. We also found significant positive correlations between the food preference ranking and the content of the minerals copper and magnesium. Male and female howler monkeys did not differ significantly in their food preference rankings. These results suggest this howler monkeys under human care are not opportunistic, but selective feeders with regard to maximizing their net gain of energy as only the content of carbohydrates, but not the contents of total energy, proteins, or lipids significantly correlated with the displayed food preferences. Thus, the food preferences of this primate are similar to those reported in several species of frugivorous primates tested with cultivated fruits and vegetables.

El objetivo principal de esta investigación es determinar la correlación entre el Bienestar Social y la Participación Política en adultos pertenecientes a una Comunidad Rural de Minga Guazú, Alto Paraná. La muestra está conformada por 70 adultos, sin discriminación de sexo. Se aplicó un diseño descriptivo y correlacional. El análisis de datos se realizó a través del Coeficiente de Correlación Lineal R de Pearson, obteniendo una relación positiva entre las dos escalas relacionadas. Se concluye que el Bienestar Social está ligado al grado de Participación Política que presenta la Comunidad Rural participante.
The main objective of this research is to determine the correlation between Social Welfare and Political Participation in adults belonging to a Rural Community from Minga Guazu, Alto Parana. The sample consisted of 70 adults, regardless of sex. We used a descriptive and correlational design. Data analysis was performed using the linear correlation coefficient R Pearson, obtaining a positive relationship between the two scales related. We conclude that Social Welfare is linked to the grades of political participation presented by the participant Rural Community.
RESUMO
Se llevó a cabo un análisis correlacional entre el conocimiento y uso de las nuevas tecnologías y la preferencia en la comunicación de estudiantes de segundo año de la Educación Media del Colegio Público seleccionado. La muestra fue intencional y autoseleccionada, conformada por 277 estudiantes de segundo año de la Educación Media. Se aplicó un diseño descriptivo, exploratorio y correlacional. Los instrumentos utilizados fueron los siguientes cuestionarios: "Conocimiento y Uso de las Nuevas Tecnologías de la Información y la Comunicación (NTIC's)" y "Preferencias de los jóvenes en su Comunicación Cotidiana". Los resultados reportan que existe correlación entre el conocimiento y uso y la preferencia de comunicación en los estudiantes de segundo año de la Educación Media.
It has been made a correlational analysis between knowledge and usage of new technologies and preference in communication of second year of Secondary Education (11th grade) students from a selected public school. The sample was intentional, self-selected and composed of 277 students. A descriptive, exploratory and correlational design was applied. The used instruments were the following questionnaires: "Knowledge and Usage of New Technologies of Information and Communication (NITC's)" and "Young people's Preference in Daily Communication". The results indicated that there is a correlation between knowledge and usage, and the preference of communication in students attending second year of Secondary.
