Central Argument

With this article, we propose to reformulate the Regional Security Complex Theory, by Buzan and Waever, through a South American vision, with the time frame 2008-2016. To this end, we will analyse South America through Argentina, Brazil, and Colombia, and their forms of intra and extra-regional interaction, highlighting the Colombia-United States relations, and the South American Defence Council, of the Union of South American Nations. This article is divided into a first section marked by an understanding of the Regional Complex Theory, in which we present and discuss its theoretical elements and weaknesses, and propose theoretical changes that will guide our analysis. The second section contains information about the South American Complex in the academic view, focusing on the arguments of Buzan and Waever. In the third section, we present the South American Regional Security Complex restructured, as well as the analysis of its dynamics. The central argument of the article is the need to reformulate the Theory in question for a better understanding of the complexities and unique characteristics of South America.

This article argues that Brazil went from a posture of estrangement in relation to the hemispheric project represented by the Free Trade Area of the Americas (FTAA) to a strategy of cooperative hegemony aimed at institutionalizing the South American space and increasing the costs of the FTAA for the United States. Although Brazil was initially isolated, US lack of leadership combined with events at the subregional level ended up turning the tide in the direction of Brazilian interests. These factors help to understand the current institutional configuration of South America.

Formal Recognition

Based on the morphological study of ca. 470 specimens and geographical studies, we here propose the recognition of six morphotypes within the South American Pteridium esculentum (= P. arachnoideum s.l., or P. aquilinum var. arachnoideum sensu Tryon, or P. esculentum subsp. arachnoideum sensu Thomson). Three of them are widely distributed and well-defined, and we regard them as subspecies of P. esculentum: P. esculentum subsp. arachnoideum s. str., P. esculentum subsp. campestre, comb. et stat. nov., and P. esculentum subsp. gryphus. The other three are more rare. One of these is a pedomorphic form of P. esculentum subsp. arachnoideum, which we name as P. esculentum subsp. arachnoideum var. paedomorficum, nom. nov. The other is a glabrous form of P. esculentum subsp. gryphus, which we name P. esculentum subsp. gryphus var. harpianum, var. nov. The third is a putative hybrid between P. esculentum subsp. arachnoideum and P. esculentum subsp. campestre. All six taxa are keyed, described, illustrated, mapped, and discussed. Pteridium esculentum subsp. arachnoideum s. str. forms an arc of distribution from eastern, to southern, to western South America (but not occurring west of the Andes); Pteridium esculentum subsp. campestre forms an arc of distribution from northeastern Brazil to northern South America (not occurring west of the Andes either); and P. esculentum subsp. gryphus forms an arc of distribution from western to northern South America (occurring also west of the Andes and in Galapagos). This one is morphologically more similar to the Australasian P. esculentum subsp. esculentum.

Abstract I argue that insulation via managerial coordination is a key element in any explanation about the formation of political regions among states. The key role it plays is as a tool for the maintenance of intra-regional pacific relations in the face of diffusion and contagion processes, resulting from continued security linkages with excluded extra-regional states. In order to explore these dynamics, I propose a new reconceptualization of the concept of managerial coordination based on the basic framework concept mapping tool. This leads to clarity about what managerial coordination does as a dimension of insulation. It also necessitates a revamp of the scale of interstate managerial coordination as a measuring instrument of the intensity of collective intentionality toward insulation among the members of a region. I then map the region concept of durable security complex (DSC) as the scope for the enactment of managerial coordination, based on a review of existing region concepts in the new regionalist literature. I then conduct an ideographic proof-of-concept exercise on three DSCs in the presence or absence of managerial coordination. These are the Scandinavian states, the South Asian regional security complex, and the South American Norther Tier local hierarchy. The exercise provides indicators for a number of theoretical propositions worthy of future evaluation.

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.

Alkaline Complexes

The Grenvillian Orogeny was preceded by extensive anorogenic volcanism and plutonism in the period 1500–1300 Ma in the form of rhyolites, epizonal granites, anorthosites, gabbros, alkaline complexes, and basic dykes. An analogue for the mid-Proterozoic anorogenic complexes is provided by the 2000 km by 200 km belt of anorogenic complexes in the Hoggar, Niger, and Nigeria, which contain anorthosites, gabbros, and peralkaline granites and were generated in a Cambrian to Jurassic rift that farther south led to the formation of the South Atlantic. An analogue for the 1 × 106 km2 area of 1500–1350 Ma rhyolites (and associated epizonal granites) that underlie the mid-continental United States is provided by the 1.7 × 106 km2 area of Jurassic Tobifera rhyolites in Argentina, which were extruded on the stretched continental margin of South America immediately preceding the opening of the South Atlantic. The mid-Proterozoic complexes were intruded close to the continental margin of the Grenvillian ocean and were commonly superimposed by the craton-directed thrusts that characterized the final stages of the Grenvillian Orogeny. The bulk of the Keweenawan rift and associated anorogenic magmatism formed about 1100 Ma at the same time as the Ottawan Orogeny in Ontario, which probably resulted from the collision of the island arc of the Central Metasedimentary Belt attached to the continental block in the east with the continental block to the west. The most appropriate modern equivalent would be the Rhine Graben, which formed at the same time as the main Alpine compression.

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.

This chapter presents a sermon by Maurice N. Eisendrath, delivered on the third Rosh Hashanah of the war. The situation of Canadian rabbis was precariously positioned between those of American preachers to the south and British preachers to the east. Canada, as part of the British Commonwealth, had long been part of the war effort, so the debate over whether or not to enter the war was not an issue, as it still was for colleagues in the United States. On the other hand, Canada was not directly affected by the war as was Britain, where one year earlier London had suffered a sustained air attack unprecedented in its devastation (a situation that certainly affected the mood in Toronto on the previous Rosh Hashanah, as the preacher reminds his listeners). Now, although the battles on the recently opened Eastern Front were of almost unimaginable ferocity, to many Canadians the war seemed distant; life at home seemed almost normal, as it did to many in the United States. This was precisely the mindset that Eisendrath set out to censure.
