  This article discusses the political projects of civilizational level, which are designed and implemented in South America. The author examines MERCOSUR as the largest regional civilizational political project, its sociocultural foundation and institutional superstructure; functionality of the “core state” in formation and maintenance of the South American civilizational political project; problems of development and future implementation. The article reveals conflict potential of MERCOSUR, as well as sociocultural capabilities for its overcoming by the “core state” of the project. The research was conducted via application of civilizational-project methodology of interpretation of policy, which is based on methodological synthesis of the principles of project approach with provisions of the theory of civilizations. The author was able to determine the value grounds of MERCOSUR, which comprise its sociocultural foundation; identify the countries competing for status of the “core state” within the framework of this project. The nature of commonality between the key participants of the projects is identified. Problems and prospect of further development of MERCOSUR civilizational projects are defined.

This research is an attempt to uncover the reality and method of Israeli penetration in the South American continent, and aims to draw attention to the weaknesses and mistakes in the role of Arab communities that they had to play in South America, and the position of Arab governments towards that continent. The research was divided into two main axes, as the first dealt with the means of Israeli penetration in South America until 1947, providing a brief overview of the roots of the penetration in the South American continent and the methods it adopted in achieving this. While the second axis focused on the stance of the South American countries on the Arab-Israeli conflict (1947-1973). However, the Israeli infiltration was affecting the political decision-makers in that continent towards the decision to partition Palestine up to the October 1973 war.

The Impact

During the warm season 2002-2003, the South American Low-Level Jet Experiment (SALLJEX) was carried out in southeastern South America. Taking advantage of the unique database collected in the region, a set of analyses is generated for the SALLJEX period assimilating all available data. The spatial and temporal resolution of this new set of analyses is higher than that of analyses available up to present for southeastern South America. The aim of this paper is to determine the impact of assimilating data into initial fields on mesoscale forecasts in the region, using the Brazilian Regional Atmospheric Modeling System (BRAMS) with particular emphasis on the South American Low-Level Jet (SALLJ) structure and on rainfall forecasts. For most variables, using analyses with data assimilated as initial fields has positive effects on short term forecast. Such effect is greater in wind variables, but not significant in forecasts longer than 24 hours. In particular, data assimilation does not improve forecasts of 24-hour accumulated rainfall, but it has slight positive effects on accumulated rainfall between 6 and 12 forecast hours. As the main focus is on the representation of the SALLJ, the effect of data assimilation in its forecast was explored. Results show that SALLJ is fairly predictable however assimilating additional observation data has small impact on the forecast of SALLJ timing and intensity. The strength of the SALLJ is underestimated independently of data assimilation. However, Root mean square error (RMSE) and BIAS values reveal the positive effect of data assimilation up to 18-hours forecasts with a greater impact near higher topography.

Abstract. The Community Climate Model (CCM3) from the National Center for Atmospheric Research (NCAR) is used to investigate the effect of the South Atlantic sea surface temperature (SST) anomalies on interannual to decadal variability of South American precipitation. Two ensembles composed of multidecadal simulations forced with monthly SST data from the Hadley Centre for the period 1949 to 2001 are analysed. A statistical treatment based on signal-to-noise ratio and Empirical Orthogonal Functions (EOF) is applied to the ensembles in order to reduce the internal variability among the integrations. The ensemble treatment shows a spatial and temporal dependence of reproducibility. High degree of reproducibility is found in the tropics while the extratropics is apparently less reproducible. Austral autumn (MAM) and spring (SON) precipitation appears to be more reproducible over the South America-South Atlantic region than the summer (DJF) and winter (JJA) rainfall. While the Inter-tropical Convergence Zone (ITCZ) region is dominated by external variance, the South Atlantic Convergence Zone (SACZ) over South America is predominantly determined by internal variance, which makes it a difficult phenomenon to predict. Alternatively, the SACZ over western South Atlantic appears to be more sensitive to the subtropical SST anomalies than over the continent. An attempt is made to separate the atmospheric response forced by the South Atlantic SST anomalies from that associated with the El Niño – Southern Oscillation (ENSO). Results show that both the South Atlantic and Pacific SSTs modulate the intensity and position of the SACZ during DJF. Particularly, the subtropical South Atlantic SSTs are more important than ENSO in determining the position of the SACZ over the southeast Brazilian coast during DJF. On the other hand, the ENSO signal seems to influence the intensity of the SACZ not only in DJF but especially its oceanic branch during MAM. Both local and remote influences, however, are confounded by the large internal variance in the region. During MAM and JJA, the South Atlantic SST anomalies affect the magnitude and the meridional displacement of the ITCZ. In JJA, the ENSO has relatively little influence on the interannual variability of the simulated rainfall. During SON, however, the ENSO seems to counteract the effect of the subtropical South Atlantic SST variations on convection over South America.

O ciclo de governos progressistas no Brasil, que começou com a eleição de Lula em 2002 e terminou com a derrubada de Dilma Rousseff em 2016, foi responsável por uma política externa autônoma que procurou reposicionar o país e a América do Sul no sistema internacional. Os governos do Partido dos Trabalhadores (PT) lideraram uma coalizão produtivista heterogênea formada por frações da burguesia industrial e setores das classes trabalhadoras. Lula teve um papel importante na criação da Unasul, que constitui a dimensão política do regionalismo sul-americano. A ruptura da ordem democrática levou ao poder uma coalizão conservadora que reunificou as elites empresariais e alterou a orientação da política externa. A coalizão liderada pelo MDB-PSDB tem adotado uma política externa que subordinou o Brasil à potência hegemônica e vem contribuindo para a paralisia e a desconstrução da Unasul enquanto bloco geopolítico.ABSTRACTThe cycle of progressive governments in Brazil, which begun with Lula’s election in 2002 and ended with the overthrow of Dilma Rousseff in 2016, was responsible for an autonomous foreign policy that sought to reposition the country and South America in the international system. The Workers Party’s (PT) governments led a heterogeneous productivist coalition made up of fractions of the industrial bourgeoisie and sectors of the working classes. Lula played an important role in the creation of Unasur, which is the political dimension of South American regionalism. The rupture of the democratic order brought to power a conservative coalition that reunified the business elites and changed the orientation of foreign policy. The coalition led by MDB-PSDB has adopted a foreign policy that subordinated Brazil to the hegemonic power and has contributed to the paralysis and the deconstruction of Unasur as a geopolitical bloc.Palavras-chave: Política externa brasileira; coalizões políticas; UnasulKeywords: Brazilian foreign policy; political coalitions; UnasurRecebido em 6 de Julho de 2018 | Received on July 6, 2018Aceito em 6 de Setembro de 2018 | Accepted on September 6, 2018

Here we present an overview of speleothem δ18O records from South America, most of which are available in the Speleothem Isotopes Synthesis and Analysis (SISAL_v1) database. South American tropical and subtropical speleothem δ18O time series are primarily interpreted to reflect changes in precipitation amount, the amount effect, and consequently history of convection intensity variability of convergence zones such as the Intertropical Convergence Zone (ITCZ) and the South America Monsoon System (SAMS). We investigate past hydroclimate scenarios in South America related to the South American Monsoon System in three different time periods: Late Pleistocene, Holocene, and the last two millennia. Precession driven summertime insolation is the main driver of convective variability over the continent during the last 120 kyrs (from present day to 120 kyrs BP), including the Holocene. However, there is a dipole between speleothem δ18O records from western and eastern South America. Records located in the central region of Brazil are weakly affected by insolation-driven variability, and instead are more susceptible to the variability associated with the South Atlantic Convergence Zone (SACZ). Cold episodic events in the Northern Hemisphere, such as Heinrich and Bond Events, and the Little Ice Age, increase the convective activity of the SAMS, resulting in increased precipitation amount in South America.

The 1950S

For all approaches to the South African past the icon of Jan Van Riebeeck looms large. Perspectives supportive of the political project of white domination created and perpetuate the icon as the bearer of civilization to the sub-continent and its source of history. Opponents of racial oppression have portrayed Van Riebeeck as public (history) enemy number one of the South African national past. Van Riebeeck remains the figure around which South Africa's history is made and contested.But this has not always been the case. Indeed up until the 1950s, Van Riebeeck appeared only in passing in school history texts, and the day of his landing at the Cape was barely commemorated. From the 1950s, however, Van Riebeeck acquired centre stage in South Africa's public history. This was not the result of an Afrikaner Nationalist conspiracy but arose out of an attempt to create a settler nationalist ideology. The means to achieve this was a massive celebration throughout the country of the 300th anniversary of Van Riebeeck's landing. Here was an attempt to display the growing power of the apartheid state and to assert its confidence.A large festival fair and imaginative historical pageants were pivotal events in establishing the paradigm of a national history and constituting its key elements. The political project of the apartheid state was justified in the festival fair through the juxtaposition of ‘civilization’ and economic progress with ‘primitiveness’ and social ‘backwardness’. The historical pageant in the streets of Cape Town presented a version of South Africa's past that legitimated settler rule.Just as the Van Riebeeck tercentenary afforded the white ruling bloc an opportunity to construct an ideological hegemony, it was grasped by the Non-European Unity Movement and the African National Congress to launch political campaigns. Through the public mediums of the resistance press and the mass meeting these organizations presented a counter-history of South Africa. These oppositional forms were an integral part of the making of the festival and the Van Riebeeck icon. In the conflict which played itself out in 1952 there was a remarkable consensus about the meaning of Van Riebeeck's landing in 1652. The narrative constructed, both by those seeking to establish apartheid and those who sought to challenge it, represented Van Riebeeck as the spirit of apartheid and the originator of white domination. The ideological frenzy in the centre of Cape Town in 1952 resurrected Van Riebeeck from obscurity and historical amnesia to become the lead actor on South Africa's public history stage.

<p>The northwest of South America is conformed by the territories of Ecuador, Colombia and Venezuela. Great part of these territories make up the Northern Andes Block (BAN). The tectonic and volcanic activity in the northwest of South America is directly related to the interaction of the South American plate, and the Nazca and Caribbean plates, with the Maracaibo and Panama-Chocó micro plates. The high seismic activity and the high magnitude of the recorded earthquakes make any study necessary to define this complex geodynamic region more precisely. This work presents the velocity models obtained through GNSS-GPS observations obtained in public continuous monitoring stations in the region. The observations of the Magna-eco network (Agustín Codazzi Geographic Institute) are integrated with models already obtained by other authors from the observations of the GEORED network (Colombian Geological Service). The observations have been processed using Bernese software v.52 using the PPP technique; obtaining topocentric time series. To obtain the speeds, a process of filtering and adjustment of the topocentric series has been carried out. Based on this velocity model, regional structures have been defined within the Northern Andes Block through a differentiation process based on the corresponding speeds of the South American, Nazca and Caribbean tectonic plates. Local geodynamic structures within the BAN itself have been established through cluster analysis based on both the direction and the magnitude of each of the vectors obtained. Finally, these structures have been correlated with the most significant geodynamic elements (fractures, faults, subduction processes, etc.) and with the associated seismic activity.</p>
