Origin and evolution of Upper Triassic to Miocene clay-mineral associations from the eastern Algarve of Portugal

XRD-analyses of pelitic deposits of Upper Jurassic to Miocene age occuring in the eastern Algarve (Portugal), give evidence of the occurrence of detrital clay minerals of continental origin as well as of conspicuous neoformations of marine provenance. The vertical succession of clay-mineral associations indicates the existence of three distinctive evolutionary cycles which are thought to reflect tectonically controlled transgressive-regressive events.

Fisioterapia e reabilitação em Portugal : o financiamento como factor crítico do desempenho

RESUMO - Num contexto em que a prestação de cuidados de Fisioterapia e Reabilitação é identificada como apresentando uma desigualdade e desajustamento da oferta regional superior à dos restantes cuidados de saúde, assim como uma falta de adequação dos preços praticados, perante as condições de oferta e procura actualmente existentes, o presente trabalho tem por objectivo investigar, no domínio do Desempenho, a influência do Financiamento na definição da prestação destes cuidados, tendo como pressuposto genérico que as decisões estratégicas e a reestruturação produtiva das organizações de saúde são condicionadas pelo sistema de preços. Considera-se que o actual sistema de Financiamento/Pagamento provoca um constrangimento na qualidade da resposta destes cuidados a dois níveis: um primeiro nível, ao colocar o pagamento no âmbito dos Meios Complementares de Diagnóstico e Terapêutica (MCDTs) a contratar pelo Serviço Nacional de Saúde, com isso determinando a configuração organizativa do sistema; um segundo nível de constrangimento que incide sobre as estruturas das organizações prestadoras, pela modelação que induz, nomeadamente a nível da sua produção. Na impossibilidade de tratar as duas dimensões do problema, pela falta de indicadores de desempenho deste sector, analisou-se, relativamente ao segundo nível de constrangimento, a produção de fisioterapia de três organizações que, potencialmente, teriam o mesmo o mesmo perfil de oferta por se enquadrarem num mesmo perfil de procura. Os resultados reflectem o pressuposto genérico do trabalho e abrem espaço para colocar como futura hipótese de investigação a razão da(s) causa(s) que poderão estar subjacentes à discrepância encontrada na média de tratamentos por sessão (duas vezes e meia) na produção das duas organizações que foi possível comparar.------------------- ABSTRACT - In a context where the provision of Physical Therapy and Rehabilitation care is identified as having a regional mismatch of supply and inequality above all the others health cares, and a lack of adequacy of prices in the current conditions of supply and demand, the present work has, as main purpose, to investigate, in the field of Performance, the Payment’s influence in shaping the provision of such health care. The general assumption tracking this analysis is that the strategic decisions on productive structure of health care organizations are influenced by the price systems. It is considered that the current Finance / Payment system causes two levels of constraints on the quality of such health care: a first constraint, as it putts its payment under the Supplementary Means of Diagnosis and Therapy (MCDTs), witch ends up establishing the organizational setup of the system; a second level of constraint by modelling the internal structure of these organizations. The lack of indicators characterizing the performance of this sector, addressed the present study to the second dimension, in witch was analysed the physical therapy production in three organizations that, potentially, would have the same profile of supply responding to similar characteristics of demand. The results reflect the above mentioned general assumption that supported the work, and leave an open space for future research, about the reason (s) that lay behind the discrepancy found between the average of treatments per session (two and a half times) in

Geography of the Information Society

All every day activities take place in space. And it is upon this that all information and knowledge revolve. The latter are the key elements in the organisation of territories. Their creation, use and distribution should therefore occur in a balanced way throughout the whole territory in order to allow all individuals to participate in an egalitarian society, in which the flow of knowledge can take precedence over the flow of interests. The information society depends, to a large extent, on the technological capacity to disseminate information and, consequently, the knowledge throughout territory, thereby creating conditions which allow a more balanced development, from the both the social and economic points of view thus avoiding the existence of info-exclusion territories. Internet should therefore be considered more than a mere technology, given that its importance goes well beyond the frontiers of culture and society. It is already a part of daily life and of the new forms of thinking and transmitting information, thus making it a basic necessity essential, for a full socio-economic development. Its role as a platform of creation and distribution of content is regarded as an indispensable element for education in today’s society, since it makes information a much more easily acquired benefit.”…in the same way that the new technologies of generation and distribution of energy allowed factories and large companies to establish themselves as the organisational bases of industrial society, so the internet today constitutes the technological base of the organisational form that characterises the Information Era: the network” (CASTELLS, 2004:15). The changes taking place today in regional and urban structures are increasingly more evident due to a combination of factors such as faster means of transport, more efficient telecommunications and other cheaper and more advanced technologies of information and knowledge. Although their impact on society is obvious, society itself also has a strong influence on the evolution of these technologies. And although physical distance has lost much of the responsibility it had towards explaining particular phenomena of the economy and of society, other aspects such as telecommunications, new forms of mobility, the networks of innovation, the internet, cyberspace, etc., have become more important, and are the subject of study and profound analysis. The science of geographical information, allows, in a much more rigorous way, the analysis of problems thus integrating in a much more balanced way, the concepts of place, of space and of time. Among the traditional disciplines that have already found their place in this process of research and analysis, we can give special attention to a geography of new spaces, which, while not being a geography of ‘innovation’, nor of the ‘Internet’, nor even ‘virtual’, which can be defined as one of the ‘Information Society’, encompassing not only the technological aspects but also including a socio-economic approach. According to the last European statistical data, Portugal shows a deficit in terms of information and knowledge dissemination among its European partners. Some of the causes are very well identified - low levels of scholarship, weak investments on innovation and R&D (both private and public sector) - but others seem to be hidden behind socio-economical and technological factors. So, the justification of Portugal as the case study appeared naturally, on a difficult quest to find the major causes to territorial asymmetries. The substantial amount of data needed for this work was very difficult to obtain and for the islands of Madeira and Azores was insufficient, so only Continental Portugal was considered for this study. In an effort to understand the various aspects of the Geography of the Information Society and bearing in mind the increasing generalised use of information technologies together with the range of technologies available for the dissemination of information, it is important to: (i) Reflect on the geography of the new socio-technological spaces. (ii) Evaluate the potential for the dissemination of information and knowledge through the selection of variables that allow us to determine the dynamic of a given territory or region; (iii) Define a Geography of the Information Society in Continental Portugal.

Internet Geography: New Spaces of Information

The objective of great investments in telecommunication networks is to approach economies and put an end to the asymmetries. The most isolated regions could be the beneficiaries of this new technological investments wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services or products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical and real space, location is defined by two or three geographical co-ordinates. In the network virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. The Internet Geography, Cybergeography or Geography of Cyberspace are only three examples. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to Internet dissemination and regional development studies. The Portuguese territory is seen in a completely new form: the IP address distribution of Country Code Top Level Domains (.pt) could show new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to reflect the info-structural dynamic and economic development of a territory, especially at regional level.

Sondagem de Belverde (Cenozóico, Península de Setúbal, Portugal). Diagrafias

In the aim of the project "Recognition of the Miocene of the distal region of the Lower Tagus Basin through a borehole with continuous sampling", Temperature, Natural Gamma Ray, Neutron (almost in all the borehole), Sonic, SP and SPR (in two small sections in upper and lower parts of the Miocene Series) geophysical logs were carried on. Interpretation of those logs and comparison with chronological, lithostratigraphical, micropaleontological and clay mineraIs data; helped in the definition of depositional sequences and to obtain paleoenvironmental reconstructions that could lead to a better understanding of the evolution of the Setúbal Península and Lisboa regions Miocene gulf. Log data agree with the lithologic succession observed in the Belverde borehole, essentially silty sandstones/sandy siltstones (with variable clay content) to clays, often with marly intercalations. Sonic logs (and Neutron logs, in general) reflect the sediments porosity. The higher acoustic velocities are often related to compact/massive layers as claystones and/or limestones and rather fossiliferous marly layers. Lower values are obtained for porous, silty sandstones (fossiliferous and with scarce clay content) and bio-calcareous sandstones. As indicative, we obtained the mean values of 2500-3000m/s for the higher velocities and 1300-1600m/s for the lowest ones. ln Natural Gamma Ray log, the radiation peaks can be correlated to often fossiliferous marly micaceous layers. Radioactive micas are present. It seems that the gamma peaks and the depositional sequences previously defined for the Lower Tagus Basin (see Antunes et al., 1999, 2000; Pais et al., 2002) can be correlated, taking also into account the whole available micropaleontological, palynological and isotopic evidence.

Educação alimentar infantil: potencialidades de estudantes de educação de infância

Resumo: Na promoção de comportamentos alimentares saudáveis ao longo da vida. que deve iniciar-se o mais precocemente possível, a educação alimentar é um elemento chave. O jardim-de-infância é um espaço efectivo na implementação de projectos de educação alimentar, onde os educadores de infância são actores imprescindíveis. Este estudo teve como objectivo desenvolver uma metodologia apropriada para identificar as capacidades de estudantes de educação de infância e avaliar as suas aptidões no contexto da educação alimentar infantil. A população alvo do estudo foram estudantes do 4ºano da licenciatura em educação de infância de instituições públicas e privadas da área metropolitana de Lisboa (n=287). Construiu-se um videograma, integrador dos domínios da aprendizagem (cognitivo e afectivo) e dos factores associados aos comportamentos em saúde (predisponentes, capacitadores e de esforço). A construção dos questionários estruturou-se em: conhecimentos-atitudes-comportamentos.Pretendia-se que os estudantes transmitissem a sua opinião, de acordo com os questionários.Os estudantes manifestaram conhecimentos, no âmbito da alimentação infantil e da utilidade e aplicabilidade da educação alimentar.Nenhum estudante apresentou conhecimentos negativos, numa escala de zero a 18 valores, 86,9% obtiveram uma classificação entre 11 e 17 valores e 13,1% a classificação máxima.A atitude dos estudantes revelou-se consensual com o desejável, 98,5% apresentaram atitudes positivas face aos aspectos estruturadores das actividades de educação alimentar.No domínio do "saber fazer" 51,0% dos estudantes demonstraram fragilidades no seu desempenho/comportamento. Em conclusão, a utilização do questionário demonstrou ser apropriado para a medição dos conhecimentos, das atitudes e como forma de os estudantes, após visionarem o videograma, espelharem o seu desempenho/comportamento face à representação do educador de infância. A taxa de resposta nunca foi inferior a 98,9% (n=284). No domínio dos conhecimentos, os estudantes manifestaram concepções positivas no campo da alimentação infantil e da educação alimentar. As atitudes enfatizaram-se no domínio afectivo, nos aspectos relacionais e comunicacionais. No domínio dos comportamentos, 91,8% dos estudantes apresentaram dificuldades na identificação dos aspectos menos correctos do desempenho dos actores do video, o que pode sugerir lacunas no âmbito do "saber fazer". Abstract:Nutrition education is key element to promote lifelong healthy eating behaviours and it must begin since early stages of life. Nursery schools are an effective space in the implementation of nutrition education projects, where the nursery teachers are indispensable actors. The aim of this study was to develop an appropriate methodology to identify nursery education student´s skills and evaluate their attitudes in the childhood nutrition education's context. The study's population were students of the 4th degree in private and public nursery education universities in Lisbon metropolitan area (n=287). A video integrator of learning domains (cognitive and affective) and of factors associated with health behaviours (predisposing, enabling and reinforcing) was developed. Questionnaire´s construction was structured in: knowledge-attitudes-behaviours.According to the questionnaires students were asked to transmit their opinion. Students revealed knowledge, in the scope of the childhood nutrition and in utility and applicability of nutrition education. No students presented negative results in knowledge ina zero - 18 scale; 86,9% students obtained a classification between 11 and 17 and the maximum classification was obtained by 13.1% students. Student's attitude was according to win the desirable, 98,5% student´s revealed positive attitudes in the nutrition education's structure aspects of chilhood activities.In the domain of the "know to do" 51,0% of students showed fragilities in their performance/behaviour. In conclusion, the questionnaire´s utilization confirm to be appropriated in measurement knowledge and attitudes and also, after watching the video, as a way for students reflect their performance/behaviour face to the nursery teacher´s representation. Answer´s rate was never lower than 98.9% (n=284). In the knowledge's domain students demonstrated positive conceptions in the childhood nutrition and nutrition education's fields. Attitudes were emphasized in the effective domain in the communication and relational aspects. In behaviour's domain 91.8% students presented difficulties in identifying the less correct aspects of the video actor's performance what may suggest gaps in the "know to do" scope.
