Percurso académico, empregabilidade e satisfação dos alunos de Psicologia e de Gestão de Recursos Humanos do Universo ISLA : perceber o passado para preparar o futuro

Hoje em dia as Universidades têm uma responsabilidade acrescida devido à problemática do desemprego, e o ensino superior marca de forma significativa a vida dos indivíduos. Assim, é importante que os indivíduos se sintam satisfeitos e realizados com a sua vida académica para terem sucesso na vida profissional. Este estudo tem como objetivo analisar o percurso académico, as competências de empregabilidade adquiridas pelos ex.alunos de Psicologia e de Gestão de Recursos Humanos do ISLA de Leiria, Santarém e Gaia, bem como os níveis de satisfação que estes apresentam. Realizou-se um estudo de carácter exploratório que visa analisar os resultados ao nível do percurso académico, empregabilidade e satisfação dos alunos das duas licenciaturas do universo ISLA. A amostra é constituída por 125 ex.alunos, sendo 56% da licenciatura de Gestão de Recursos Humanos e 44% da licenciatura de Psicologia. Foi aplicado o Questionário Sócio – Demográfico para se obterem informações sobre o percurso académico e a satisfação. A Escala de Empregabilidade (Campos, K. & Freitas, F., 2008) aplicou-se para analisar os fatores de empregabilidade (facilidade de procura, dificuldade de procura, otimismo e responsabilidade e decisão). Os resultados obtidos nesta investigação sugerem que os ex.alunos se encontram, na sua maioria, satisfeitos e consideram apresentar competências de empregabilidade e mostram-nos que não existem diferenças significativas quando comparadas as licenciaturas e os três ISLA’s Apresentam-se nas conclusões as ideias mais significativas que este estudo salientou e que nos permitem compreender o presente, e projetar o futuro.

O conceito de «perceção do risco» : contributo da psicologia social

Este artigo refere-se à forma como a Psicologia Social estuda o risco, a qual parte do fenómeno intrapsíquicos para explicar as realidades em que os diferentes atores sociais se movem. Nele apresentamos os conceitos de «percepção de risco» e de «avaliação do risco». Apesar do segundo conceito ser mais objetivo que o primeiro, é o primeiro que tem maior importância na adesão a comportamentos preventivos.

Elevated marine deposits in Bermuda record a late Quaternary megatsunami

Deposits of coral-bearing, marine shell conglomerate exposed at elevations higher than 20 m above present-day mean sea level (MSL) in Bermuda and the Bahamas have previously been interpreted as relict intertidal deposits formed during marine isotope stage (MIS) I I, ca. 360-420 ka before present. On the strength of this evidence, a sea level highstand more than 20 m higher than present-day MSL was inferred for the MIS I I interglacial, despite a lack of clear supporting evidence in the oxygen-isotope records of deep-sea sediment cores. We have critically re-examined the elevated marine deposits in Bermuda, and find their geological setting, sedimentary relations, and microfaunal assemblages to be inconsistent with intertidal deposition over an extended period. Rather, these deposits, which comprise a poorly sorted mixture of reef, lagoon and shoreline sediments, appear to have been carried tens of meters inside karst caves, presumably by large waves, at some time earlier than ca. 310-360 ka before present (MIS 9-11). We hypothesize that these deposits are the result of a large tsunami during the mid-Pleistocene, in which Bermuda was impacted by a wave set that carried sediments from the surrounding reef platform and nearshore waters over the eolianite atoll. Likely causes for such a megatsunami are the flank collapse of an Atlantic island volcano, such as the roughly synchronous Julan or Orotava submarine landslides in the Canary Islands, or a giant submarine landslide on the Atlantic continental margin.

Reply to "Mega-highstand or megatsunami? Discussion of McMurtry et al. "Elevated marine deposits in Bermuda record a late Quaternary megatsunami": Sed. Geol. 200 (2007) 155-165" by Paul J. Hearty and Storrs L. Olson

Our recent paper [McMurtry, G.M., Tappin, D.R., Sedwick, P.N., Wilkinson, I., Fietzkc, J. and Sellwood, B., 2007a. Elevated marine deposits in Bermuda record a late Quaternary megatsunami. Sedimentary Geol. 200, 155-165.] critically re-examined elevated marine deposits in Bermuda, and concluded that their geological setting, sedimentary relations, micropetrography and microfaunal assemblages were inconsistent with sustained intertidal deposition. Instead, we hypothesized that these deposits were the result of a large tsunami that impacted the Bermuda island platform during the mid-Pleistocene. Hearty and Olson [Hearty, P.J., and Olson, S.L., in press. Mega-highstand or megatsunami? Discussion of McMurtry et al. "Elevated marine deposits in Bermuda record a late Quaternary megatsunami": Sedimentary Geology, 200, 155-165, 2007 (Aug. 07). Sedimentary Geol. 200, 155-165.] in their response, attempt to refute our conclusions and claim the deposits to be the result of a +21 m eustatic sea level highstand during marine isotope stage (MIS) 11. In our reply we answer the issues raised by Hearty and Olson [Hearty, P.J., and Olson, S.L., in press. Mega-highstand or megatsunami? Discussion of McMurtry et al. "Elevated marine deposits in Bermuda record a late Quaternary megatsunami": Sedimentary Geology, 200, 155-165, 2007 (Aug. 07). Sedimentary Geol. 200,155-165.] and conclude that the Bermuda deposits do not provide unequivocal evidence of a prolonged +21 m eustatic sea level highstand. Rather, the sediments are more likely the result of a past megatsunami in the North Atlantic basin. (c) 2008 Elsevier B.V. All rights reserved.

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.
