Para um diálogo e uma espiritualidade inter e trans-religiosos : uma reflexão a partir de Agostinho da Silva e de sua Santidade o XIV Dalai Lama

O objectivo deste estudo é considerar a possibilidade e exigências de um diálogo e de uma espiritualidade inter e trans-religiosos a partir das propostas de Sua Santidade o Dalai Lama e Agostinho da Silva.

(In)disciplina e (inter)ação pedagógica : do discurso às práticas

O tema deste trabalho é a (in)disciplina em contexto de sala de aula, colocando - se o enfoque nas representações alunos do 3º ciclo, pais e professores sobre esta problemática e as suas perceções sobre o tipo de ocorrências e causas. Este estudo de caso procura um entendimento da indisciplina, reconhecendo-se a existência de uma miríade de fatores subjacentes a este conceito, cruzando diferentes olhares da psicologia, sociologia e pedagogia. O conceito de indisciplina é definido com referência ao conceito de disciplina traduzindo um comportamento disruptivo que emerge na relação pedagógica. A construção da relação interpessoal entre professor/aluno e a gestão do comportamento dos alunos assegura a manutenção de um clima que permite a efetividade do processo ensino – aprendizagem. Realiza-se uma abordagem numa perspetiva conceptual, procurando-se o conhecimento e natureza do conceito, a identificação das causas centrados no aluno desde as suas características psicológicas, sócio – económicas, de contexto familiar e culturais, as causas centradas no professor e na organização escolar, bem como as causas sociais que influenciam a ocorrência de (in)disciplina. Explanam-se formas de gestão e resolução de comportamentos disruptivos, atendendo a diferentes e possíveis abordagens. Efetua-se, numa perspetiva empírica, na tentativa de compreender o impacto da interação pedagógica na ocorrência de atos disruptivos, a análise e interpretação de dados obtidos por triangulação de métodos, a partir de uma população de alunos de 3ºciclo, professores e pais, permitindo uma reflexão e confrontação sobre as representações destes atores e as realidades observadas.

A record of Holocene climate change from lake geochemical analyses in southeastern Arabia

Lacustrine sediments from southeastern Arabia reveal variations in lake level corresponding to changes in the strength and duration of Indian Ocean Monsoon (IOM) summer rainfall and winter cyclonic rainfall. The late glacial/Holocene transition of the region was characterised by the development of mega-linear dunes. These dunes became stabilised and vegetated during the early Holocene and interdunal lakes formed in response to the incursion of the IOM at approximately 8500 cal yr BP with the development of C3 dominated savanna grasslands. The IOM weakened ca. 6000 cal yr BP with the onset of regional aridity, aeolian sedimentation and dune reactivation and accretion. Despite this reduction in precipitation, the take was maintained by winter dominated rainfall. There was a shift to drier adapted C4 grasslands across the dune field. Lake sediment geochemical analyses record precipitation minima at 8200, 5000 and 4200 cal yr BP that coincide with Bond events in the North Atlantic. A number of these events correspond with changes in cultural periods, suggesting that climate was a key mechanism affecting human occupation and exploitation of this region.

Climate impacts of recent multidecadal changes in Atlantic Ocean Sea Surface Temperature: A multimodel comparison

During the twentieth century sea surface temperatures in the Atlantic Ocean exhibited prominent multidecadal variations. The source of such variations has yet to be rigorously established—but the question of their impact on climate can be investigated. Here we report on a set of multimodel experiments to examine the impact of patterns of warming in the North Atlantic, and cooling in the South Atlantic, derived from observations, that is characteristic of the positive phase of the Atlantic Multidecadal Oscillation (AMO). The experiments were carried out with six atmospheric General Circulation Models (including two versions of one model), and a major goal was to assess the extent to which key climate impacts are consistent between the different models. The major climate impacts are found over North and South America, with the strongest impacts over land found over the United States and northern parts of South America. These responses appear to be driven by a combination of an off-equatorial Gill response to diabatic heating over the Caribbean due to increased rainfall within the region and a Northward shift in the Inter Tropical Convergence Zone (ITCZ) due to the anomalous cross-equatorial SST gradient. The majority of the models show warmer US land temperatures and reduced Mean Sea Level Pressure during summer (JJA) in response to a warmer North Atlantic and a cooler South Atlantic, in line with observations. However the majority of models show no significant impact on US rainfall during summer. Over northern South America, all models show reduced rainfall in southern hemisphere winter (JJA), whilst in Summer (DJF) there is a generally an increase in rainfall. However, there is a large spread amongst the models in the magnitude of the rainfall anomalies over land. Away from the Americas, there are no consistent significant modelled responses. In particular there are no significant changes in the North Atlantic Oscillation (NAO) over the North Atlantic and Europe in Winter (DJF). Additionally, the observed Sahel drying signal in African rainfall is not seen in the modelled responses. Suggesting that, in contrast to some studies, the Atlantic Multidecadal Oscillation was not the primary driver of recent reductions in Sahel rainfall.
