Orbitally tuned time scale and astronomical forcing in the middle Eocene to early Oligocene determined on ODP and IODP sediment cores

Deciphering the driving mechanisms of Earth system processes, including the climate dynamics expressed as paleoceanographic events, requires a complete, continuous, and high-resolution stratigraphy that is very accurately dated. In this study, we construct a robust astronomically calibrated age model for the middle Eocene to early Oligocene interval (31-43 Ma) in order to permit more detailed study of the exceptional climatic events that occurred during this time, including the Middle Eocene Climate Optimum and the Eocene/Oligocene transition. A goal of this effort is to accurately date the middle Eocene to early Oligocene composite section cored during the Pacific Equatorial Age Transect (PEAT, IODP Exp. 320/321). The stratigraphic framework for the new time scale is based on the identification of the stable long eccentricity cycle in published and new high-resolution records encompassing bulk and benthic stable isotope, calibrated XRF core scanning, and magnetostratigraphic data from ODP Sites 171B-1052, 189-1172, 199-1218, and 207-1260 as well as IODP Sites 320-U1333, and -U1334 spanning magnetic polarity Chrons C12n to C20n. Subsequently we applied orbital tuning of the records to the La2011 orbital solution. The resulting new time scale revises and refines the existing orbitally tuned age model and the Geomagnetic Polarity Time Scale from 31 to 43 Ma. Our newly defined absolute age for the Eocene/Oligocene boundary validates the astronomical tuned age of 33.89 Ma identified at the Massignano (Italy) global stratotype section and point. Our compilation of geochemical records of climate-controlled variability in sedimentation through the middle-to-late Eocene and early Oligocene demonstrates strong power in the eccentricity band that is readily tuned to the latest astronomical solution. Obliquity driven cyclicity is only apparent during very long eccentricity cycle minima around 35.5 Ma, 38.3 Ma and 40.1 Ma.

Relative abundances of selected radiolarian species in sediments of ODP Leg 199 sites

During Ocean Drilling Program (ODP) Leg 199, sediments were recovered from eight sites in the Central Pacific. Late Oligocene and early Miocene radiolarians are common to abundant and moderately well preserved in Cores 199-1218A-8H through 11H and 199-1219A-5H through 9H. More than 110 radiolarian species were encountered during this study. Of these species, 100 are identifiable forms and the rest are undescribed or unfamiliar forms. This report presents the relative abundances of described forms from the upper Oligocene to lower Miocene sediments.

The Connor-Davidson Resilience Scale (CD-RISC): Dimensionality and age-related measurement invariance with Australian cricketers

Objective This study explored the dimensionality and measurement invariance of the 25-item Connor-Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003) across samples of adult (n = 321; aged 20–36) and adolescent (n = 199; aged 12–18) Australian cricketers. Design Cross-sectional, self-report survey Methods An online, multi-section questionnaire. Results Confirmatory factor and item level analyses supported the psychometric superiority of a revised 10-item, unidimensional model of resilience over the original 25-item, five-factor measurement model. Positive and moderate correlations with hardiness as well as negative and moderate correlations with burnout components were evidenced thereby providing support for the convergent validity of the unidimensional model. Measurement invariance analyses of the unidimensional model across the two age-group samples supported configural (i.e., same factor structure across groups), metric (i.e., same pattern of factor loadings across the groups), and partial scalar invariance (i.e., mostly the same intercepts across the groups). Conclusion Evidence for a psychometrically sound measure of resilient qualities of the individual provides an important foundation upon which researchers can identify the antecedents to and outcomes of resilience in sport contexts.

Diário da Constituinte [gravação de vídeo] : [programa n. 199]

Começa na Assembleia Nacional Constituinte (ANC) o debate das emendas populares e cada uma delas será defendida por representantes da sociedade. O primeiro debate das emendas populares será sobre os seguintes temas: direitos da mulher, saúde da mulher, família, direitos da família, aposentadoria da mulher. No projeto do Relator Bernardo Cabral (PMDB-AM) a mulher perdeu o direito a uma aposentadoria especial e só vai se aposentar após 35 anos de contribuição. A Deputada Beth Azize (PSB-AM) convoca as mulheres para defender a aposentadoria após 25 anos de serviço. A Bancada Nordestina volta a reunir-se e decide ampliar o movimento unindo-se com constituintes do Norte e do Centro-Oeste, em defesa de uma reforma tributária mais justa que beneficie as regiões mais pobres e subdesenvolvidas. O Deputado José Luiz Maia(PDS-PI) considera que é necessário que o bolo tributário seja dividido equitativamente e que o orçamento seja aplicado regionalmente. O Deputado Átila Lira (PFL-PI) afirma que a regionalização dos investimentos diminuirá as diferenças. O Deputado Ubiratan Aguiar (PMDB-CE) diz que basta de discriminação contra o Nordeste. Definidos os pontos pendentes do substitutivo: na reforma agrária a imissão de posse será depois de 90 dias da desapropriação, a anistia será parcial e o sistema de governo será o parlamentarismo. O Senador Fernando Henrique Cardoso (PMDB-SP) explica como será o parlamentarismo previsto no substitutivo. O Deputado Bernardo Cabral (PMDB-AM) entrega o projeto ao Presidente da Assembleia Nacional Constituinte (ANC) Ulysses Guimarães (PMDB-SP). O Deputado Bernardo Cabral (PMDB-AM) informa sobre o mandato do Presidente Sarney e sobre a implementação do parlamentarismo. Opinião dos constituintes sobre o sistema de governo. O Deputado Francisco Carneiro (PMDB-DF) considera que o melhor sistema de governo é o presidencialismo, com um presidente forte, um Poder Legislativo na plenitude de suas prerrogativas e um Poder Judiciário autônomo. O Deputado Francisco Coelho (PFL-MA) sugere a instituição do parlamentarismo por etapas. O Deputado Michel Temer (PMDB-SP) informa que o parlamentarismo é um regime muito grandioso que não deve ser desmerecido sem uma consulta popular. O Senador José Fogaça (PMDB-RS) informa que o parlamento não pode oferecer ao povo brasileiro o dilema de escolher entre o ruim, que é o presidencialismo, e o desconhecido, que é o parlamentarismo.
