Historia de una película: Las tres ratas (Del Fabulador)

El estreno de la película Las tres ratas, basada en la novela homónima de Alfredo Pareja, se realizó en 1946 en Argentina y, en Ecuador, dos años después. Aunque inicialmente el autor se sintiera muy desencantado con esta adaptación, participó en la recuperación de la misma, y su reestreno en 1989, en un contexto muy distinto. En este año culminaba el proyecto -iniciado en 1981 por Cinemateca Nacional- de acopiar el patrimonio cinematográfico del Ecuador, como memoria del país. En 1989, la institución gestionó la declaratoria del cine ecuatoriano como parte del Patrimonio Cultural del Estado, y la delegación de esa custodia a la misma Cinemateca. Alfredo Pareja tuvo un rol importante en la recuperación, por vía diplomática, de una copia de Las tres ratas, y contribuyó adicionalmente con documentos relativos a varias películas del novelista Demetrio Aguilera Malta. Fue un impulsor del proyecto global, pese a la ambigüedad de sentimientos vinculados con los estrenos de cuarenta años atrás, de lo cual da fe un fragmento de carta de Alfredo Pareja al pintor Galo Galecio, de 1946.

Influence of foliar diseases and their control by fungicides on grain yield and quality in wheat

Twenty-eight field experiments on sandy-loam soils in the UK (1982-2003) are reviewed by relating the extension of the green area duration of the flag leaf (GLADF) by fungicides to effects on yield and quality of winter wheat. Over all experiments mean grain yield = 8.85t ha(-1) at 85% DM. With regards quality, mean values were: thousand grain weight (TGW) = 44.5 g; specific weight (SWT) = 76.9 kg hl(-1); crude protein concentration (CP (N x 5.7)) = 12.5 % DM; Hagberg falling number (HFN) = 285 s; and sodium dodecyl sulphate (SDS)-sedimentation volume = 69ml. For each day (d) that fungicides increased GLADF there were associated average increases in yield (0.144 1 ha(-1) d(-1), se 0.0049, df = 333), TGW (0.56 gd(-1), se = 0.017) and SWT (0.22 kg hl(-1) d(-1), se 0.011). Some curvature was evident in all these relationships. When GLADF was delayed beyond 700 degrees Cd after anthesis, as was possible in cool wet seasons, responses were curtailed, or less reliable. Despite this apparent terminal sink limitation, fungicide effects on sink size, eg endosperm cell numbers or maximum water mass per grain, were not prerequisites for large effects on grain yield, TGW or SWT. Fungicide effects on CP were variable. Although the average response of CP was negative (-0.029%DM/d; se = 0.00338), this depended on cultivar and disease controlled. Controlling biotrophs such as rusts, (Puccinia spp.) tended to increase CP, whereas controlling a more necrotrophic pathogen (Septoria tritici) usually reducedCP. Irrespective of pathogen controlled, delaying senescence of the flag leaf was associated with increased nitrogen yields in the grain (averaging 2.24 kg N ha-1 d(-1), se = 0.0848) due to both increased N uptake into the above ground crop, and also more efficient remobilisation of N from leaf laminas. When sulphur availability appeared to be adequate, fungicide x cultivar interactions were similar on S as for CP, although N:S ratios tended to decline (i.e. improve for bread making) when S. tritici was controlled. On average, SDS-sedimentation volume declined (-0. 18 ml/d, se = 0.027) with increased GLADF, broadly commensurate with the average effect on CP. Hagberg falling number decreased as fungicide increased GLADF (-2.73 s/d, se = 0.178), indicating an increase in alpha-amylase activity.

The Granada ignimbrite: A compound pyroclastic unit and its relationship with Upper Miocene caldera volcanism in the northern Puna

The Granada ignimbrite, an Upper Miocene volcanic unit from the northern Puna, previously has been interpreted as an extensive ignimbrite (>2300 km(2)) associated with eruptions from the Vilama caldera (trap-door event). On the basis of new data, we revise its correlation and redefine the unit as a compound, high aspect ratio ignimbrite, erupted at approximately 9.8 Ma. Calculated volumes (similar to 100 km(3)) are only moderate in comparison with other large volume (>1000 km(3)) ignimbrites that erupted approximately 2-6 m.y. later in the region (e.g. Vilama, Panizos, Atana). Six new volcanic units are recognized from sequences previously correlated with Granada (only one sourced from the same center). Consequently, the area ascribed to the Granada ignimbrite is substantially reduced (630 km(2)), and links to the Vilama caldera are not supported. Transport directions suggest the volcanic source for the Granada ignimbrite corresponds to vents buried under younger (>= 7.9-5 Ma) volcanic rocks of the Abra Granada volcanic complex. Episodes of caldera collapse at some stage of eruption are likely, though their nature and timing cannot be defined from available data. The eruption of the Granada ignimbrite marks the onset of a phase of large volume (caldera-sourced) volcanism in the northern Puna. (C) 2007 Elsevier Ltd. All rights reserved.

Mother’s experiences and perceptions of a continuous caring model with fathers after caesarean section : a qualitative study

Background: In Chile, mothers and newborns are separated after caesarean sections. The caesarean section rate in Chile is approximately 40%. Once separated, newborns will miss out on the benefits of early contact unless a suitable model of early newborn contact after caesarean section is initiated. Aim: To describe mothers experiences and perceptions of a continuous parental model of newborn care after caesarean section during mother-infant separation. Methods: A questionnaire with 4 open ended questions to gather data on the experiences and perceptions of 95 mothers in the obstetric service of Sótero Del Rio Hospital in Chile between 2009 and 2012. Data were analyzed using qualitative content analysis. Results: One theme family friendly practice after caesarean section and four categories. Mothers described the benefits of this model of caring. The fathers presence was important to mother and baby. Mothers were reassured that the baby was not left alone with staff. It was important for the mothers to see that the father could love the baby as much as the mother. This model of care helped create ties between the father and newborn during the period of mother-infant separation and later with the mother. Conclusions: Family friendly practice after caesarean section was an important health care intervention for the whole family. This model could be stratified in the Chilean context in the case of complicated births and all caesarean sections. Clinical Implications: In the Chilean context, there is the potential to increase the number of parents who get to hold their baby immediately after birth and for as long as they like. When the mother and infant are separated after birth, parents can be informed about the benefits of this caring model. Further research using randomized control trials may support biological advantages.

Processos e componentes mantélicos no norte da Patagônia (Argentina) e relações com a subducção Andina : Evidências petrográficas, geoquímicas e isotópicas em xenólitos ultramáficos mantélicos

Xenólitos ultramáficos, carregados até a superfície da Terra por magmatismo básico alcalino intraplaca, fornecem evidências diretas da natureza e processos envolvidos em modificações do manto litosférico subcontinental, como fusão parcial e metassomatismo. Estes xenólitos têm sido utilizados para identificar processos relacionados a evolução da litosfera continental, estimar a composição original do manto e a escala das heterogeneidades mantélicas. Raramente xenólitos ultramáficos mantélicos são encontrados em ambientes convergentes, no entanto na Patagônia (sul da América do Sul), diversas ocorrências são identificadas em basaltos alcalinos na região de arco e back arc da Cordilheira do Andes. Estes xenólitos oportunizam o estudo dos processos de interação entre a cunha mantélica, a placa oceânica subductada e a astenosfera. Nesta dissertação são apresentados dados petrográficos, mineralógicos, geoquímicos e de isótopos de Sr e O em 22 xenólitos ultramáficos de dois centros vulcânicos Mioceno-Holoceno distintos: Cerro del Mojon (41°06’S-70°13’W) e Estancia Alvarez (40°46’S-68°46’W), localizados na borda NW do Platô de Somuncura, norte de Patagônia (Argentina). A suíte de xenólitos ultramáficos do Cerro del Mojon consiste de espinélio dunitos e harzburgitos mantélicos anidros (Grupo1), espinélio lherzolitos mantélicos anidros (Grupo 2a) e hidratados (Grupo 2b) e espinélio clinopiroxenitos crustais (Grupo 3). Os xenólitos mantélicos do Grupo 1 são depletados (empobrecidos em ETR pesados e HFSE, com baixas razões 87Sr/86Sr em Cpx – 0,7028-0.7037), de alta PT (16-19 kbar, 950-1078 ºC), e têm evidências de metassomatismo críptico (enriquecimento em K, Na ETR leves) atribuído a componentes derivados de sedimentos da placa oceânica subductada, EM 2 (87Sr/86Sr em RT até 0,7126, 87Rb/86Sr até 1,66 e δ18O até +6.78‰). Estes valores anomalamente altos foram obtidos em amostras com bolsões de reação ao redor do espinélio, induzidos pela percolação de fluidos metassomáticos sob altas pressões seguida por descompressão (Sp+fluido→ Cpx+Ol+Sp+melt-andesítico-traquítico). Os xenólitos do Grupo 2 são moderadamente depletados (empobrecidos em HFSE, com baixas a altas razões 87Sr/86Sr em RT e Cpx – 0,7031-0,7045 e δ18O +5-6.2‰), de baixa PT (14-15 kbar, 936-942 ºC), e têm evidências de metassomatismo modal e críptico (enriquecimento em ETR leves, Na, K, Ti, Sr, Hf e anfibólio modal). O metassomatismo críptico parece estar relacionado ao mesmo agente metassomatizante do Grupo 1, mas ocorre em menor intensidade. O metassomatismo modal, no entanto, tem outra origem, podendo ser derivado de fontes mantélicas profundas. A quebra do anfibólio metassomático durante a descompressão e ascensão dos xenólitos até a superfície formou bolsões de reação ao redor do anfibólio (Anf→Cpx+Ol+Sp+melts-basálticos & andesíticos). A suíte de xenólitos ultramáficos de Estancia Alvarez consiste de espinélio harzburgitos anidros mantélicos (Grupo 1a) e espinélio dunitos anidros crustais (Grupo 1b), ambos com veios de serpentina. Os xenólitos mantélicos do Grupo 1a são depletados (empobrecidos em ETR leves e HFSE), de profundidades variadas (P entre 11-18 kbar) e de baixa T (877-961 ºC). Estes xenólitos têm enriquecimento em ETR leves, B, Rb e K, que pode estar relacionado a percolação de fluidos ricos em H2O e LILE gerados pela desidratação de filossilicatos dos sedimentos da placa oceânica (EM 2), como evidenciado por veios de serpentina e altas razões 87Sr/86Sr (0,7046-0,7298), 87Rb/86Sr (0,07-5,63) e valores de δ18O (até +7,88‰).

Financial regulation and international criminal policy: the anti-money laundering system in Brazil and Argentina

The objective of this paper is to present and compare the process and the results of the implementation of the anti-money laundering system in Brazil and Argentina. Considering that the internal transformations cannot be discussed without a clear understanding of the international apparatus, attention will be given to the description of the “international policy” designed and conducted by FATF. Therefore, its incorporation into two different national realities, the Brazilian and the Argentinean ones, will shed light not only on the transnational transformations both States underwent but also on the anti-money laundering regime itself. The paper is divided into five parts. The first one presents a brief introduction on the emergence and development of the relationship between financial regulation and criminal policy. The two following sections are designed to present an overview of the anti money laundering system in Brazil and Argentina and of the role of FATF in their implementation process. The fourth section presents two Brazilian examples of situations in which full advantage of the FATF regime was taken: the National Strategy to Combat Corruption and Money Laundering and the BacenJud, a communication channel between the financial system and the judicial power. To conclude, final comments will be presented in connection with the central questions of the project this paper is part of .

Infrastructure and productivity in Latin America: is there a relationship in the long run?

This article analyses the relationship between infrastructure and total factor productivity (TFP) in the four major Latin American economies: Argentina, Brazil, Chile and Mexico. We hypothesise that an increase in infrastructure has an indirect effect on long-term economic growth by raising productivity. To assess this theory, we use the traditional Johansen methodology for testing the cointegration between TFP and physical measures of infrastructure stock, such as energy, roads, and telephones. We then apply the Lütkepohl, Saikkonen and Trenkler Test, which considers a possible level shift in the series and has better small sample properties, to the same data set and compare the two tests. The results do not support a robust long-term relationship between the series; we do not find strong evidence that cuts in infrastructure investment in some Latin American countries were the main reason for the fall in TFP during the 1970s and 1980s.

Latitudinal variation in population structure and reproductive pattern of the endemic south american shrimp Artemesia longinaris (Decapoda : Penaeoidea)

Population Structure and reproductive Maturity of females were investigated in the shrimp Artemesia longinaris Bate, 1888 from coastal waters of northern São Paulo State (Brazil. 23 degrees S) and Mar del Plata (Argentina, 38 degrees S) from June 2001 to May 2002. Monthly collections were taken by, commercial shrimp fishing boats equipped with bottom trawl nets. Population parameters from size frequency distributions and size (carapace length = CL) of female reproductive maturity were analyzed and compared front the two sampling areas. Latitudinal trends in reproductive parameters of A. longinaris were shown in overall body size and size of reproductive maturity, both of which were smaller in females from the tropical location than those front the cold-temperate sampling area. Largest females (> 30 turn CL) were collected in Argentina, while Brazilian specimens reached maximum size at 27 nun CL. The smallest Size of female sexual maturity was estimated at 13.6 nun CL in Brazilian samples compared to 22.1 mm CL calculated for those from Argentina. Populations from both regions exhibited a bimodal size distribution in the spring, with the peak at small body size probably corresponding to recent recruits and the peak at larger body, size to reproductive females or shrimps migrating in from deeper waters or other latitudinal regions. In late spring and summer. an intrusion of the cold South Atlantic Coastal Water mass was observed which lowered water temperature and stimulated plankton production. The primary food source for the larvae of a typically cold-temperate species such as A. longinaris. The trend of increasing body size and delay of sexual maturity with increasing latitude appears to be correlated with the decreasing water temperature and increasing plankton productivity at higher latitudes.

Biotic interaction between spionid polychaetes and bouchardiid brachiopods: Paleoecological, taphonomic and evolutionary implications

Shells of Bouchardia rosea (Brachiopoda, Rhynchonelliformea) are abundant in Late Holocene death assemblages of the Ubatuba Bight, Brazil, SW Atlantic. This genus is also known from multiple localities in the Cenozoic fossil record of South America. A total of 1211 valves of B. rosea, 2086 shells of sympatric bivalve mollusks (14 nearshore localities ranging in depth from 0 to 30 m), 80 shells of Bouchardia zitteli, San Julián Formation, Paleogene, Argentina, and 135 shells of Bouchardia transplatina, Camacho Formation, Neogene, Uruguay were examined for bioerosion traces. All examined bouchardiid shells represent shallow-water, subtropical marine settings. Out of 1211 brachiopod shells of B. rosea, 1201 represent dead individuals. A total of 149 dead specimens displayed polychaete traces (Caulostrepsis). Live polychaetes were found inside Caulostrepsis borings in 10 life-collected brachiopods, indicating a syn-vivo interaction (Caulostrepsis traces in dead shells of B. rosea were always empty). The long and coiled peristomial palps, large chaetae on both sides of the 5th segment, and flanged pygidium found in the polychaetes are characteristic of the polychaete genus Polydora (Spionidae). The fact that 100% of the Caulostrepsis found in living brachiopods were still inhabited by the trace-making spionids, whereas none was found in dead hosts, implies active biotic interaction between the two living organisms rather than colonization of dead brachiopod shells. The absence of blisters, the lack of valve/site stereotypy, and the fact that tubes open only externally are all suggestive of a commensal relationship. These data document a new host group (bouchardiid rhynchonelliform brachiopods) with which spionids can interact (interestingly, spionid-infested sympatric bivalves have not been found in the study area despite extensive sampling). The syn-vivo interaction indicates that substantial bioerosion may occur when the host is alive. Thus, the presence of such bioerosion traces on fossil shells need not imply a prolonged post-mortem exposure of shells on the sea floor. Also, none of the Paleogene and Neogene Bouchardia species included any ichnological evidence for spionid infestation. This indicates that the Spionidae/ Bouchardia association may be geologically young, although the lack of older records may also reflect limited sampling and/or taphonomic biases.
