O Lugar como Simbiose : Centro Histórico de Torres Vedras

A presente dissertação tem como principal objectivo a análise morfológica do centro histórico de Torres Vedras. Após um rigoroso estudo do seu plano estratégico de reabilitação urbana, verifica-se a ausência de um documento complementar que permita conhecer sua identidade. A informação existente é bastante planimétrica, pouco esclarecedora da qualidade espacial do Lugar. Devido à escassa cartografia existente, julgou-se essencial desenvolver a reconstituição urbanística da cidade, permitindo dissipar algumas memórias artificiais, fomentadas pelo ‘neo-romantismo’ do Estado Novo, mas que ainda hoje se fazem sentir na memória colectiva dos torrienses. O estudo da génese fundacional do Lugar e do seu enquadramento histórico é fundamental para o entendimento do valor patrimonial enquanto conceito subjacente às políticas de reabilitação dos centros históricos. O estudo da evolução urbana de Torrres Vedras desde a vila medieval, até à cidade do séc. XXI, dando a conhecer os pólos de atracção do crescimento periurbano, e a sua relação com o centro histórico, permitiu um conhecimento mais aprofundado sobre os elementos essenciais que caracterizam a sua Identidade. Verifica-se que a matriz urbana fundacional, ainda hoje perceptível, provém da ocupação romana, materializada pelos dois principais eixos reguladores: cardus e decumanus. A leitura do passado, alicerçada sobre a historiografia e arqueologia, pretende apenas mostrar que os núcleos urbanos antigos foram sempre elementos dinâmicos, capazes de se adaptarem às circunstâncias de cada época, garantindo a sua permanência e importância até ao início do séc. XX. A abordagem feita ao centro histórico pretende demonstrar a sua potencialidade para se tornar num elemento activo da cidade de Torres Vedras, capaz de se adaptar às necessidades da sociedade do séc. XXI, sem perder a sua identidade.

СЛІДИ КОНФЛІКТУ – ПОЛІТИЧНІ В’ЯЗНІ У ПРОЗІ ЗОФІЇ НАЛКОВСЬКОЇ

The main aim of the article is highlighting subplots present in the prose works of Nałkowska which are devoted to Ukrainian and Belarusian political prisoners. The author maintains that the Polish colonizing activity along the so-called ‘Eastern Borderland’ requires a detailed and comprehensive study. The results of this analys is should then be compared against contemporary Ukrainian literature as well as the history of the national liberation and nationalist movements at the beginning of 20th century. The article explores three prose texts by Nałkowska, that is, “Węzły życia” (The Bonds of Life), “Niedobra miłość” (Bad Love) and “Ściany świata” (The Walls of the World). The subplots present in all three works can be analyzed in terms of inevident, yet indelible traces pertaining to ethnic conflicts between Poles, Ukrainians and Belarusians, as well as the Jewish pogroms. The themes that span the above- mentioned text can be outlined as follows: first of all, the radical metamorphosis of political attitudes on the part of the protagonists representing former Legionists; secondly, the heroines’ active work for the benefit of the prisoners, also the political ones. In spite of censorship and visibly more and more extreme politics of the authoritarian state towards ethnic minorities, Nałkowska remained one of the few writers who managed to deliver the arrested history of persecutions. Keywords: politics of colonization, national minority, traces of conflict, political prisoners

The prediction of extratropical storm tracks by the ECMWF and NCEP ensemble prediction systems

The prediction of extratropical cyclones by the European Centre for Medium Range Weather Forecasts (ECMWF) and the National Centers for Environmental Prediction (NCEP) Ensemble Prediction Systems (EPS) has been investigated using an objective feature tracking methodology to identify and track the cyclones along the forecast trajectories. Overall the results show that the ECMWF EPS has a slightly higher level of skill than the NCEP EPS in the northern hemisphere (NH). However in the southern hemisphere (SH), NCEP has higher predictive skill than ECMWF for the intensity of the cyclones. The results from both EPS indicate a higher level of predictive skill for the position of extratropical cyclones than their intensity and show that there is a larger spread in intensity than position. Further analysis shows that the predicted propagation speed of cyclones is generally too slow for the ECMWF EPS and show a slight bias for the intensity of the cyclones to be overpredicted. This is also true for the NCEP EPS in the SH. For the NCEP EPS in the NH the intensity of the cyclones is underpredicted. There is small bias in both the EPS for the cyclones to be displaced towards the poles. For each ensemble forecast of each cyclone, the predictive skill of the ensemble member that best predicts the cyclones position and intensity was computed. The results are very encouraging showing that the predictive skill of the best ensemble member is significantly higher than that of the control forecast in terms of both the position and intensity of the cyclones. The prediction of cyclones before they are identified as 850 hPa vorticity centers in the analysis cycle was also considered. It is shown that an indication of extratropical cyclones can be given by at least 1 ensemble member 7 days before they are identified in the analysis. Further analysis of the ECMWF EPS shows that the ensemble mean has a higher level of skill than the control forecast, particularly for the intensity of the cyclones, 2 from day 3 of the forecast. There is a higher level of skill in the NH than the SH and the spread in the SH is correspondingly larger. The difference between the ensemble mean and spread is very small for the position of the cyclones, but the spread of the ensemble is smaller than the ensemble mean error for the intensity of the cyclones in both hemispheres. Results also show that the ECMWF control forecast has ½ to 1 day more skill than the perturbed members, for both the position and intensity of the cyclones, throughout the forecast.

Mesozoic climates: General circulation models and the rock record

General circulation models (GCMs) use the laws of physics and an understanding of past geography to simulate climatic responses. They are objective in character. However, they tend to require powerful computers to handle vast numbers of calculations. Nevertheless, it is now possible to compare results from different GCMs for a range of times and over a wide range of parameterisations for the past, present and future (e.g. in terms of predictions of surface air temperature, surface moisture, precipitation, etc.). GCMs are currently producing simulated climate predictions for the Mesozoic, which compare favourably with the distributions of climatically sensitive facies (e.g. coals, evaporites and palaeosols). They can be used effectively in the prediction of oceanic upwelling sites and the distribution of petroleum source rocks and phosphorites. Models also produce evaluations of other parameters that do not leave a geological record (e.g. cloud cover, snow cover) and equivocal phenomena such as storminess. Parameterisation of sub-grid scale processes is the main weakness in GCMs (e.g. land surfaces, convection, cloud behaviour) and model output for continental interiors is still too cold in winter by comparison with palaeontological data. The sedimentary and palaeontological record provides an important way that GCMs may themselves be evaluated and this is important because the same GCMs are being used currently to predict possible changes in future climate. The Mesozoic Earth was, by comparison with the present, an alien world, as we illustrate here by reference to late Triassic, late Jurassic and late Cretaceous simulations. Dense forests grew close to both poles but experienced months-long daylight in warm summers and months-long darkness in cold snowy winters. Ocean depths were warm (8 degrees C or more to the ocean floor) and reefs, with corals, grew 10 degrees of latitude further north and south than at the present time. The whole Earth was warmer than now by 6 degrees C or more, giving more atmospheric humidity and a greatly enhanced hydrological cycle. Much of the rainfall was predominantly convective in character, often focused over the oceans and leaving major desert expanses on the continental areas. Polar ice sheets are unlikely to have been present because of the high summer temperatures achieved. The model indicates extensive sea ice in the nearly enclosed Arctic seaway through a large portion of the year during the late Cretaceous, and the possibility of sea ice in adjacent parts of the Midwest Seaway over North America. The Triassic world was a predominantly warm world, the model output for evaporation and precipitation conforming well with the known distributions of evaporites, calcretes and other climatically sensitive facies for that time. The message from the geological record is clear. Through the Phanerozoic, Earth's climate has changed significantly, both on a variety of time scales and over a range of climatic states, usually baldly referred to as "greenhouse" and "icehouse", although these terms disguise more subtle states between these extremes. Any notion that the climate can remain constant for the convenience of one species of anthropoid is a delusion (although the recent rate of climatic change is exceptional). (c) 2006 Elsevier B.V.

The potential to narrow uncertainty in projections of regional precipitation change

We separate and quantify the sources of uncertainty in projections of regional (*2,500 km) precipitation changes for the twenty-first century using the CMIP3 multi-model ensemble, allowing a direct comparison with a similar analysis for regional temperature changes. For decadal means of seasonal mean precipitation, internal variability is the dominant uncertainty for predictions of the first decade everywhere, and for many regions until the third decade ahead. Model uncertainty is generally the dominant source of uncertainty for longer lead times. Scenario uncertainty is found to be small or negligible for all regions and lead times, apart from close to the poles at the end of the century. For the global mean, model uncertainty dominates at all lead times. The signal-to-noise ratio (S/N) of the precipitation projections is highest at the poles but less than 1 almost everywhere else, and is far lower than for temperature projections. In particular, the tropics have the highest S/N for temperature, but the lowest for precipitation. We also estimate a ‘potential S/N’ by assuming that model uncertainty could be reduced to zero, and show that, for regional precipitation, the gains in S/N are fairly modest, especially for predictions of the next few decades. This finding suggests that adaptation decisions will need to be made in the context of high uncertainty concerning regional changes in precipitation. The potential to narrow uncertainty in regional temperature projections is far greater. These conclusions on S/N are for the current generation of models; the real signal may be larger or smaller than the CMIP3 multi-model mean. Also note that the S/N for extreme precipitation, which is more relevant for many climate impacts, may be larger than for the seasonal mean precipitation considered here.
