Variables psicopedagógicas relacionadas con el rendimiento en EGB.

Influencia de la aptitudes mentales, inteligencia, intereses, rasgos de personalidad, actitudes y adaptación en todos sus campos, en las calificaciones obtenidas por los alumnos de octavo de EGB en La Rioja. De los 455 alumnos de octavo de EGB de nueve centros de La Rioja de tipo urbano, suburbano, rural y semirural se obtuvieron los datos completos de 386 alumnos. Fueron divididos en cinco categorías: baja-muy baja, media baja, media, media alta y alta-muy alta. Muestra no representativa. Estudio experimental que intenta cuantificar la relación existente entre las variables independientes y las aptitudes mentales-cálculo verbal y razonamiento-, inteligencia general verbal y no verbal, intereses o preferencias, adaptación y rasgos de personalidad y la variable dependiente, el rendimiento escolar al finalizar octavo de EGB. Test de aptitudes escolares Tea-2, test de inteligencia general adaptado por M. Yela CSIC Madrid, d-48 versión Española: M. Yela, test Cappa 's' forma a de J. A. San Martin, inventario de adaptación, test de preferencias profesionales en EGB Gonzalo Ugarte, Lujan Castro.. Correlación de Pearson simple, parcial y múltiple. Existe una correlación marcada y positiva entre las calificaciones obtenidas y la inteligencia aunque esta sea más alta sobre la adaptación escolar. La correlación es positiva entre el rendimiento y la adaptación global del alumno. La inteligencia es un factor influyente en la higiene mental. La correlación múltiple es baja entre la inteligencia y la adaptación. Los alumnos de octavo que suspenden muestran preferencia por la actividades artísticas, sociales y mecánicas. La elección de actividades científicas es muy baja en los alumnos de inteligencia inferior a la media. La inteligencia es la variable más influyente de las consideradas. sigue por orden de influencia la adaptación a la vida escolar. La relación entre adaptación e inteligencia puede considerarse como indiferente. Existe una influencia alta entre: adaptación a la vida escolar, a los profesores y a los compañeros, a la vida familiar y a la vida moral con la adaptación global del alumno. Los alumnos con alta emotividad y resonancia obtienen bajas calificaciones, sin embargo en los que tienen alto control voluntario los suspensos disminuyen.

Ocorrência de Leishmania spp. em felinos do município de Araçatuba, SP

Este trabalho teve como objetivo comparar a ocorrência de Leishmania spp. em gatos por dois métodos (citológico e sorológico), bem como associar a ocorrência deste protozoário com as variáveis sexo, idade e raça. Amostras séricas de 283 felinos domésticos foram testadas pela Reação de Imunofluorescência Indireta (RIFI), e o exame parasitológico direto de linfonodos também foi realizado para a verificação da positividade para Leishmania spp. Ocorrência de 0,7% (2/283) foi observada nos felinos examinados, por meio de imprint de linfonodos e nenhum animal apresentou títulos de anticorpos para Leishmania spp. As duas fêmeas positivas eram sem raça definida, sendo uma jovem e outra adulta. Por meio dos resultados obtidos, não foi constatada diferença estatisticamente significante em relação às variáveis sexo, raça e idade nos gatos desta pesquisa (p > 0,05). Ocorrência de Leishmania spp. nos gatos deste estudo foi baixa. Devido a esta baixa incidência sugere-se que estes não assumem importância epidemiológica na área do estudo.

Inter and intraspecific variation on reproductive phenology of the Brazilian Atlantic forest Rubiaceae: Ecology and phylogenetic constraints

The reproductive phenology of seven species of Rubiaceae from the Brazilian Atlantic rain forest was compared to evaluate the occurrence of phylogenetic constraints on flowering and fruiting phenologies. Since phenological patterns can be affected by phylogenetic constraints, we expected that reproductive phenology would be similar among plants within a family or genus, occurring during the same time (or season) of the year. Observations on flowering and fruiting phenology were carried out monthly, from December 1996 to January 1998, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, Ubatuba, São Paulo State, Brazil. Nine phenological variables were calculated to characterize, quantify and compare the reproductive phenology of the Rubiaceae species. The flowering patterns were different among the seven species studied, and the Kruskal-Wallis test indicated significant differences in flowering duration, first flowering, peak flowering and flowering synchrony. The peaks and patterns of fruiting intensity were different among the Rubiaceae species studied and they differed significantly from conspecifics in the phenological variables fruiting duration, fruiting peak date, and fruiting synchrony (Kruskal-Wallis test). Therefore, we found no evidence supporting the phylogenetic hypotheses, and climate does not seem to constrain flowering and fruiting patterns of the Rubiaceae species in the understory of the Atlantic forest.

Care arrangements for people with dementia in developing countries

Background: Rapid demographic ageing will soon lead to large increases in the numbers of persons with dementia in developing countries. This study is the first comprehensive assessment of care arrangements for people with dementia in those regions. Methods: A descriptive and comparative study of dementia care; caregiver characteristics, the nature of care provided, and the practical, psychological (Zarit Burden Interview, General Health Questionnaire) and economic impact upon the caregiver in 24 centres in India, China and South East Asia, Latin America and the Caribbean and Africa. Results: We interviewed 706 persons with dementia, and their caregivers. Most caregivers were women, living with the person with dementia in extended family households. One-quarter to one-half of households included a child. Larger households were associated with lower caregiver strain, where the caregiver was co-resident. However, despite the traditional apparatus of family care, levels of caregiver strain were at least as high as in the developed world. Many had cutback on work to care and faced the additional expense of paid carers and health services. Families from the poorest countries were particularly likely to have used expensive private medical services, and to be spending more than 10% of the per capita GNP on health care. Conclusions: Older people in developing countries are indivisible from their younger family members. The high levels of family strain identified in this study feed into the cycle of disadvantage and should thus be a concern for policymakers in the developing world.

STAT3 and SOCS3 expression patterns during murine placenta development

Signal transducers and activators of transcription 3 (STAT3) has been identified as an important signal transducer in the invasive phenotype of the trophoblasts cells in in vitro studies. However, the in situ distribution and patterns of expression of this molecule in trophoblast cells during the development of the placenta are still under-elucidated. Mice uteri of gestational ages between 7 and 14 days of pregnancy (dop) were fixed in methacarn and processed with immunoperoxidase techniques for detection of STAT3 and its phosphorylation at serine (p-ser727) residues, as well as the suppressor of cytokine signaling 3 (SOCS3) expression. STAT3 was observed at 7 through 9 dop in both the antimesometrial and mesometrial deciduas, while continued immunoreactivity between 10 and 13 dop was seen only in the mesometrial decidua. In the placenta, STAT3 was detected in the cytotrophoblast cells of labyrinth and giant trophoblast cells between 10 and 14 dop. Immunoreactivity for STAT3 was also seen in trophoblast cells surrounding the maternal blood vessels. On days 10 and 11 of pregnancy, p-ser727 was detectable in the mesometrial decidua and in giant trophoblasts, while during 12-14 dop in the spongiotrophoblast region. In addition, SOCS3 was immunodetected in maternal and placental tissues, principally in the giant trophoblast cells during the whole period of the study. The present in situ study shows the distribution of STAT3, its serine activation and SOCS3 in different maternal and fetal compartments during murine placental development, thus further supporting the idea that they play a role during physiological placentation in mice.

Matters of taste: the neoclassical furniture in the Italian portraits from the late eighteenth century to the Restoration

Analysis and description of the furniture shown on Italian portraits from the late eighteenth century to the period of the Restoration. We have studied real examples of environments still exist with their furniture, chairs, mirrors, lamps, etc. in different areas of Italy. All this to explain the refined taste and cosmopolitan of the characters painted in the portraits, that for this reason they were considered fashionable
