A influência de fatores psicossociais protetores sobre a incidência de dor dentária
2022
ABSTRACT OBJECTIVE To investigate the influence of protective psychosocial factors on the incidence of dental pain in the last six months among 12-year-old children living in Manaus (AM). METHODS A prospective school-based cohort study was conducted with 210 12-year-old students enrolled in public schools in the eastern zone of Manaus (AM). Students were followed up for two years. Validated questionnaires were used to assess sociodemographic characteristics, protective psychosocial factors, including sense of coherence, social support, and self-esteem at baseline and after two years. Calibrated examiners clinically assessed dental caries and gingival bleeding. Multivariate multilevel Poisso…

Consiste en una entrada redactada para una enciclopedia anglosajona en la que se trata acerca de las fundaciones coloniales griegas en la cuenca de los mares Mediterráneo y Negro, con los viajes exploratorios, la consulta al Oráculo de Delfos y los consabidos rituales de fundación.
Pollination of four sympatric species ofAngelonia (Scrophulariaceae) by oil-collecting bees in NE. Brazil
1991
The manner whereby the oil-producing bisaccate flowers ofAngelonia (Scrophulariaceae) are pollinated by female oil-collecting bees is reported for the first time. Observations were made in the Caatinga formation of Pernambuco, NE. Brazil, on four synchronopatric species. These differ in sizes and structural details of the corolla, level of flower exposition, and habitat preferences. All legitimate visitors wereCentris spp. (Anthophoridae):Angelonia hirta was mainly pollinated byC. fuscata andA. pubescens byC. hyptidis; A. bisaccata andA. hookeriana shared an unidentified species. Several exomalopsine, tetrapediine and meliponid bees exploit the flowers less descriminately for oil or pollen,…
The perfume flowers ofCyphomandra (Solanaceae): Pollination by euglossine bees, bellows mechanism, osmophores, and volatiles
1993
The perfume syndrome and pollination by fragrance-collecting euglossine bees in the neotropic solanaceous genusCyphomandra was confirmed by field observations. In SE Brazil,C. sciadostylis was visited byEufriesea violaceae, andC. diploconos byEuglossa mandibularis; C. hartwegii was pollinated byEulaema meriana in Costa Rica. The primary attractant, fragrant droplets that ooze from the dorsally bulged connectives, is mopped up by the males with the forebasitarsi. Thereby, the poricidal thecae are inadvertently pushed causing the dry pollen to dust the bee's sternum. The number and direction of the pollen jets are related to pollinator size and stigma structure. The flowers are homogamous, se…
Die Ölblumensymbiosen - Parallelismus and andere Aspekte ihrer Entwicklung in Raum and Zeit1, 2
2009
The oil-bee/oil-flower relationships: parallelism and other aspects of their evolution in space and time A survey is given of our present knowledge and existing hypotheses concerning the biogeography, history, and phylogeny of plant taxa yielding fatty oil as a floral reward, and of the bee genera involved in their pollination. Four syngenetic complexes of the symbiosis arose convergently: The neotropical, the paleotropical, the holarctic, and the capensic complex. On the basis of the mutual structural adaptations of bees and flowers it is concluded that, in addition, parallelism within related groups as a result of a common tendency to develop the respective organs, has played an important…
Programas Educativos Universitarios Para Mayores: Evaluación de su Impacto en la Autopercepción del Apoyo Social y la Salud Mental
2015
Algunos estudios indican que los programas universitarios para mayores pueden tener un impacto positivo en la autopercepción del apoyo social y la salud de los participantes. Sin embargo, dichos estudios no evalúan estas variables con instrumentos de medida estandarizados y grupos de control dentro y fuera del programa. En el presente trabajo se utilizó un grupo experimental y dos grupos control que fueron evaluados en dos momentos con instrumentos estandarizados. Los resultados no confirmaron los efectos beneficiosos esperados de los programas. Es necesario seguir profundizando en esta línea de actuación y explorar el efecto de variables socioafectivas en estudios longitudinales. Some stud…
PK-yritysten kybervalmius
2018
Pienet ja keskisuuret yritykset joutuvat yhä enenemissä määrin kyberhyökkäyksen kohteeksi. PK-yrityksen päätöksenteko keskittyy yrityksen toimitusjohtajalle ja häntä avustaville avainhenkilöille, joiden tietämys ei aina riitä kattamaan yrityksen kyberturvallisuutta. Johtuen pienestä henkilöstömäärästä ja suurista suhteellisista koulutuskustannuksista, PK-yritykset suhtautuvat epäröiden henkilöstön kouluttamiseen kyberturvallisuuden alalla. Kyberturvallisuuden näkökulmasta PK-yritystä uhkaavat useat eri toimijat, joiden motiivit ja toimintatavat vaihtelevat. Yleisimpinä hyökkäystapoina ovat tietojenkalasteluviestit, erilaiset huijausyritykset sekä haittaohjelmat. Pystyäkseen vastaamaan uhkii…
