From Global North to Global South

Globalization and science fiction are reflected—and refracted—in the globalization of science fiction. Much of my work on early Latin American sf has examined the great degree to which science fiction is and has long been a global genre, read and written around the world, forming a planet-spanning continuity—or, to use Damien Broderick’s terminology, a “megatext web” made up of “collective intertextualit[ies]” (“Megatext,” The Encyclopedia of Science Fiction. Online. 18 Aug. 2012). Yet I am constantly tripping over ways in which sf is not global or at least not so global as I had unconsciously slipped into assuming it was

By Burro and by Beagle: Geographic Journeys through Time in Latin American Science Fiction

This essay extends Bud Foote\u27s theory of a link between geographical and temporal travel in Northern science fiction to include the science fiction of the Southern hemisphere. It examines two tales of marvelous overland journeys that were set in the Latin America of the day but which represented travel to the nations\u27 natural, historical, and cultural pasts: the Brazilian Augusto Emflio Zaluar\u27s 0 Doutor Benignus (Docwr Bemgnu.s) and the Argentine Eduardo Ladislao Holmberg\u27s Dos partidos en lucha: Fan, wsw cientifica (livo Factions Struggle for Life: A Scientific Fantasy). Despite marked dissmiliarities between the backgrounds and world views of their writers, these two novels hare common influences and deal with themes of scientific and pseudoscientific uses of evolutionary theories, national progress through the spread of scientific knowledge, and the representation of South America as the locus for a utopian future

The First Wave: Latin American Science Fiction Discovers Its Roots

This essay examines three of the earliest works of Latin American sf together for the first time: México en el año 1970 [Mexico in the Year 1970, 1844, Mexico], Páginas da história do Brasil escripta no anno de 2000 [Pages from the History of Brazil Written in the Year 2000, 1868-72, Brazil], and Viaje maravilloso del Señor Nic-Nac al planeta Marte [The Marvelous Journey of Mr. Nic-Nac to the Planet Mars, 1875-76, Argentina]. Nineteenth-century works such as these have been added to the genealogical tree of Latin American sf in recent years. The addition of pre-space-age texts to the corpus of Latin American sf does more than provide its writers and readers with local roots: it broadens our understanding of the genre in Latin America and the periphery; it extends our perceptions of the role of science in Latin American literature and culture; and, together with later Latin American sf, it contributes new perspectives and new narrative possibilities to the genre as a whole

Writing Other Futures: A Conversation about Science Fiction

CentraI to The Other Trans-Atlantic is the contention that kinetic art was a species of realism, reflecting the new socioeconomic realities emerging in the geographies considered by our project. In seeking to test the hypothesis that the pervasive curiosity, if not enthusiasm, for science and technology, as refracted through the lens of innovative artistic practices, led to the embrace of optical and kinetic forms, we,the editors, wondered if we might find correlating interests in other artistic languages and cultural forms. In trying to understand the way in which these forces (industrialization, scientific discovery, etc) changed everyday life and therefore shaped visual culture, we happened pan two books, We Modern People: Science Fiction and the Making of Russian Modernity by Anindita Banerjee and The Emergence of Lain American Science Fiction by Rachel Haywood Ferreira. It became clear that kinetic and Op artists were applying in the visual field what Science fiction writers were doing in the literary field, namely reflecting the present and imagining the future. We invited Banerjee and Rachel Haywood-Ferreira to help us understand the complexities of the cultural moment using science fiction as a lens.-Eds

Ground-based aerosol characterization during the South American Biomass Burning Analysis (SAMBBA) field experiment

This paper investigates the physical and chemical characteristics of aerosols at ground level at a site heavily impacted by biomass burning. the site is located near Porto Velho, Rondonia, in the southwestern part of the Brazilian Amazon rainforest, and was selected for the deployment of a large suite of instruments, among them an Aerosol Chemical Speciation Monitor. Our measurements were made during the South American Biomass Burning Analysis (SAMBBA) field experiment, which consisted of a combination of aircraft and ground-based measurements over Brazil, aimed to investigate the impacts of biomass burning emissions on climate, air quality, and numerical weather prediction over South America. the campaign took place during the dry season and the transition to the wet season in September/October 2012.During most of the campaign, the site was impacted by regional biomass burning pollution (average CO mixing ratio of 0.6 ppm), occasionally superimposed by intense (up to 2 ppm of CO), freshly emitted biomass burning plumes. Aerosol number concentrations ranged from similar to 1000 cm(-3) to peaks of up to 35 000 cm(-3) (during biomass burning (BB) events, corresponding to an average submicron mass mean concentrations of 13.7 mu g m(-3) and peak concentrations close to 100 mu g m-3. Organic aerosol strongly dominated the submicron non-refractory composition, with an average concen-tration of 11.4 mu g m(-3). the inorganic species, NH4, SO4, NO3, and Cl, were observed, on average, at concentrations of 0.44, 0.34, 0.19, and 0.01 mu g m(-3), respectively. Equivalent black carbon (BCe) ranged from 0.2 to 5.5 mu g m(-3), with an average concentration of 1.3 mu g m(-3). During BB peaks, organics accounted for over 90% of total mass (submicron non-refractory plus BCe), among the highest values described in the literature.We examined the ageing of biomass burning organic aerosol (BBOA) using the changes in the H : C and O : C ratios, and found that throughout most of the aerosol processing (O : C congruent to D 0 : 25 to O : C congruent to D 0 : 6), no remarkable change is observed in the H : C ratio (similar to 1 : 35). Such a result contrasts strongly with previous observations of chemical ageing of both urban and Amazonian biogenic aerosols. At higher levels of processing (O : C > 0 : 6), the H : C ratio changes with a H : C / O : C slope of -0.5, possibly due to the development of a combination of BB (H : C / O : C slope D 0) and biogenic (H : C / O : C slope D 1) organic aerosol (OA). An analysis of the Delta OA / Delta CO mass ratios yields very little enhancement in the OA loading with atmospheric processing, consistent with previous observations. These results indicate that negligible secondary organic aerosol (SOA) formation occurs throughout the observed BB plume processing, or that SOA formation is almost entirely balanced by OA volatilization.Positive matrix factorization (PMF) of the organic aerosol spectra resulted in three factors: fresh BBOA, aged BBOA, and low-volatility oxygenated organic aerosol (LV-OOA). Analysis of the diurnal patterns and correlation with external markers indicates that during the first part of the campaign, OA concentrations are impacted by local fire plumes with some chemical processing occurring in the near-surface layer. During the second part of the campaign, long-range transport of BB plumes above the surface layer, as well as potential SOAs formed aloft, dominates OA concentrations at our ground-based sampling site.This manuscript describes the first ground-based deployment of the aerosol mass spectrometry at a site heavily impacted by biomass burning in the Amazon region, allowing a deeper understanding of aerosol life cycle in this important ecosystem.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)INCT AmazoniaNatural Environment Research Council (NERC)Univ São Paulo, Inst Phys, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Earth & Exact Sci, Diadema, BrazilUniv Manchester, Sch Earth Atmospher & Environm Sci, Ctr Atmospher Sci, Manchester, Lancs, EnglandUK Met Off, Exeter, Devon, EnglandUniv Exeter, Coll Engn Maths & Phys Sci, Exeter, Devon, EnglandNatl Inst Space Res INPE, Sao Jose Dos Campos, BrazilMax Planck Inst Chem, Biogeochem Dept, D-55128 Mainz, GermanyUniversidade Federal de São Paulo, Dept Earth & Exact Sci, Diadema, BrazilFAPESP: 2012/14437-9FAPESP: 2013/05014-0CNPq: 475735-2012-9Natural Environment Research Council (NERC): NE/J010073/1Web of Scienc

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
