Published: September 2014

A vegetação da região nordeste do estado do Paraná, situada norevés do escarpamento estrutural Furnas, compreende um mosaico composto por fragmentos de florestas, campos e cerrados. Essa impressionante diversidade fisionômica, deve-se a dois motivos principais. Em primeiro lugar a região abriga uma das áreas de transição entre cerrados do Brasil central e florestas estacionais semidecíduais do sudeste e sul do país. Em segundo lugar esta transição se verifica em pleno limite de ocorrência das espécies típicas dos campos sulinos. Esses fatores são acentuados pelo escarpamento estrutural furnas, cujo relevo promove variação ambiental formando fragmentos de vegetação peculiares nas maiores altitudes. De uma maneira geral as fisionomias dos campos rupestres e campos de altitude estão associadas aos solos rasos e jovens em áreas de altitudes, ao passo que em altitudes moderadas, nos solos mais antigos e profundos, ocorrem cerrados ou florestas. Essas formações estão condicionadas à fertilidade e regime de água dos solos e freqüência de incêndios (OLIVEIRA-FILHO et al., 1994; TANNUS & ASSIS, 2004). Devido aos processos de ocupação e exploração à vegetação foi substituída por monoculturas e os relíctos, em forma de remanescentes, esparsos são inúmeras vezes perturbados pelo fogo, pecuária ou pela retirada seletiva de madeira. O Parque Estadual do Cerrado constitui uma importante amostra da vegetação da região nordeste do estado, pois seus quatro tiposfisionômicos principais (floresta, cerrado, campo e refúgio vegetacional rupestre) encontram-se bem preservados. Por estemotivo, o Parque abriga uma notável diversidade de espécies deplantas em uma área relativamente pequena, o que atraiu a atenção de pesquisadores da Universidade Federal do Paraná (e. g., LAROCA & ALMEIDA, 1994) e de outras instituições, que têm realizado ali várias expedições científicas. A primeira descrição da vegetação do Parque foi realizada por UHLMANN et al. (1995 & 1997). Os autores classificaram a vegetação em três tipos fisionômicos, floresta estacional semidecídua, cerrado e campo.O propósito do presente trabalho é de amostrar a vegetação edescrever os diferentes tipos fisionômicos, dentro de uma abordagem interpretativa na qual as variações da vegetação são associadas às diversidades ambientais.
Catálogo dos Deltocephalinae (Hemiptera: Cicadellidae) neotropicais (incluíndo o norte do México). Parte I — Athysanini e Deltocephalini excluídos

In the General Catalogue of the Homoptera (METCALF, 1967)contains 36 genera and 215 Neotropical species, including north ofMexico distributed within 10 tribes (two genera and six species inEuscelini, one genera and one species in Colladonini, one genusand one species in Goniagnathini, four genera and 52 species inAcinopterini, one genus and one species in Cicadulini, four generaand 80 species in Scaphytopiini, five genera and 32 species inBalcluthini, one genus and one species in Macrostelini, three genera and five species in Platymetopiini and 14 genera and 82 species in Scaphoideini). However, since 1967 many papers on Neotropical Deltocephalinae have been published including classification and nomenclatorial alterations, new taxa and geographical distribution. The complete bibliography of the leafhopper literature up to 1955 can be found in the General Catalogue of the Homoptera, Fascicle VI, Part 10 (METCALF, 1962-1968). OMAN et al. (1990) published a complete list of the world genera of Cicadellidae and the bibliography between 1955-1985. In this work are recorded 21 Neotropical subfamilies, 16 Neotropical tribes and 184 Neotropical genera (one genus in Acinopterini, one genus in Cicadullini, one genus in Cerrillini, six genera in Hecalini, one genus in Luheriini, two genera in Doraturini, two genera in Stenometopiini, four genera in Scaphytopiini, two genera in Platymetopiini, six genera in Scaphoideini, one genus in Balcluthini, seven genera in Macrostelini, two genera in Opsiini, one genus in Penthimiini, 40 genera in Deltocephalini and 107 genera in Athysanini); eight genera without references about the tribe. Another subfamily and genus were added by GODOY & WEBB (1994). This catalogue is an attempt to offer the names and bibliographic references for taxa of Deltocephalinae (Caribbean, Central America and South America). After each species-group name, the type locality, and anabbreviation of the institution where the type is deposited, are given. The geographical distribution is based upon previously published records. Each species-group name is followed by the informations including of the author (s), publication year and page and when not strictly taxonomical, an abbreviated indication of the matter treated such as: cat. — catalogue, desc. — description, distr. — geographical distribution, ill. — illustration, rev. — revision, syn. — synonymy, tax. — taxonomy.

Aristotele, Eraclito e la forza irresistibile del thumos (22 B 85 DK)
Authors: Viano Cristina 
Published: September 2014

Questo articolo presenta un quadro dei problemi che il frammento B85DK di Eraclito solleva e delle interpretazioni antiche e moderne che sono state suggerite. In particolare, è esaminata la testimonianza di Aristotele, la più antica e anche la più profonda e articolata. Una panoramica sui significati di thumos, punto centrale del frammento, mostra che per Aristotele questo concetto non si esaurisce nel pathos dell’ira. Il thumos è in primo luogo una dunamis, una facoltà dell’anima che rende possibile non solo il pathos, l’affezione passeggera dell’ira, ma anche il coraggio, l’impulsività, l’affetto, il senso della libertà e dell’autorità. Questa nozione aristotelica, così ricca e polimorfica da sottrarsi a una traduzione unica esaustiva, proviene in realtà dalla sistematizzazione di un materiale molto antico, omerico e presocratico, legato ai proverbi. Eraclito stesso ne offre già una formulazione che sintetizza due aspetti che Aristotele accoglie e sottolinea: la forza irresistibile e inarrestabile dello slancio impulsivo naturale, una volta che sia stato innescato, e l'estrema conseguenza a cui puo' portare, e cioè la perdita della vita stessa.
Transmission du vodou haïtien confrontée aux impératifs du changement et de la loyauté
Authors: Régulus Samuel 
Published: September 2014

Sous l’influence de plusieurs facteurs (phénomène migratoire, contexte politique, disposition théologique), le vodou - étant un système ouvert - évolue tant sur le plan de la pratique que celui du discours. L’analyse des données ethnographiques révèle que de nouvelles pratiques du vodou se déploient dans une logique de croisement entre l’impératif du changement et l’exigence de la loyauté envers la mémoire des ancêtres. Dans le temps, on reprochait au vodou son infantilisme, son arriération. Habituellement, il est sans traces écrites, confiné dans des taudis, incapable de se défendre face aux discours concurrents. Aujourd’hui, on le retrouve de plus en plus dans l’espace public : places publiques, parcours carnavalesques, radio, télévision, internet. Les initiés se regroupent dans des associations. Ils formulent des revendications politiques. Ses adeptes font usage des textes écrits dans leurs rencontres de prière et de méditation. Face à de telles pratiques, certains observateurs veulent faire « un rappel à l’ordre ». Ils regrettent que le vodou ne reste plus « soi-même ». « Il perd son authenticité ». Mais pour les « nouveaux acteurs » vodou, rester attacher à leurs racines, c’est pouvoir en toute liberté honorer les Lwa, ce qui consiste à : jeter de l’eau, tracer les vèvè, allumer les bougies, jouer les tambours, chanter et danser les Lwa, pratiquer leur médecine sacrée, garder leur rapport harmonieux avec les arbres, et continuer la fonction sociale du vodou. De ce côté, ils ne veulent pas lâcher prise. Par ailleurs, ils ne veulent pas non plus continuer à être l’objet de curiosité permettant aux « civilisés » de revisiter leur passé archéologique.

AbstractThe expected urbanization of the planet in the coming century coupled with aging infrastructure in developed regions, increasing complexity of man‐made systems, and pressing climate change impacts have created opportunities for reassessing the role of infrastructure and technologies in cities and how they contribute to greenhouse gas (GHG) emissions. Modern urbanization is predicated on complex, increasingly coupled infrastructure systems, and energy use continues to be largely met from fossil fuels. Until energy infrastructures evolve away from carbon‐based fuels, GHG emissions are critically tied to the urbanization process. Further complicating the challenge of decoupling urban growth from GHG emissions are lock‐in effects and interdependencies. This paper synthesizes state‐of‐the‐art thinking for transportation, fuels, buildings, water, electricity, and waste systems and finds that GHG emissions assessments tend to view these systems as static and isolated from social and institutional systems. Despite significant understanding of methods and technologies for reducing infrastructure‐related GHG emissions, physical, institutional, and cultural constraints continue to work against us, pointing to knowledge gaps that must be addressed. This paper identifies three challenge themes to improve our understanding of the role of infrastructure and technologies in urbanization processes and position these increasingly complex systems for low‐carbon growth. The challenges emphasize how we can reimagine the role of infrastructure in the future and how people, institutions, and ecological systems interface with infrastructure.
Formation processes of flux ropes downstream from Martian crustal magnetic fields inferred from Grad‐Shafranov reconstruction

Published: September 2014

AbstractWe applied the Grad‐Shafranov reconstruction (GSR) technique to Martian magnetic flux ropes observed downstream from strong crustal magnetic fields in the southern hemisphere. The GSR technique can provide a two‐dimensional axial magnetic field map as well as the axial orientation of flux ropes from single‐spacecraft data under assumptions that the structure is magnetohydrostatic and time independent. The reconstructed structures, including their orientation, allowed us to evaluate possible formation processes for the flux ropes. We reconstructed 297 magnetic flux ropes observed by Mars Global Surveyor between April 1999 and November 2006. Based on characteristics of their geometrical axial orientation and transverse magnetic field topology, we found that they can be mainly distinguished according to whether draped interplanetary magnetic fields overlaying the crustal magnetic fields are involved or not. Approximately two thirds of the flux ropes can be formed by magnetic reconnection between neighboring crustal magnetic fields attached to the surface. The remaining events seem to require magnetic reconnection between crustal and overlaid draped magnetic fields. The latter scenario should allow planetary ions to be transferred from closed magnetic flux tube to flux tubes connected to interplanetary space, allowing atmospheric ions to escape from Mars. We quantitatively evaluate lower limits on potential ion escape rates from Mars owing to magnetic flux ropes.
Progressive offset and surface deformation along a seismogenic blind thrust in the Po Plain foredeep (Southern Alps, Northern Italy)

Published: September 2014

AbstractHere we present, for the first time in the Po Plain foredeep (Northern Italy), the middle to late Pleistocene growth history of an outcropping secondary fold and related faults, whose progressive deformation over an intermediate time window (105 years) is driven by an underlying seismogenic blind thrust. We trenched and logged an outcropping decametric secondary anticline, related to a deeper blind compressional structure, which deforms fluvial sediments and an overlying loess‐paleosol sequence. Folded units were dated, using radiocarbon and optically stimulated luminescence methods, to the late Pleistocene–Holocene and tentatively correlated with glacial‐interglacial phases occurring during the time interval from marine isotope stage 6 to the present. A multistep retrodeformation of the fold allowed us to calculate uplift rates for this secondary and shallow anticline, varying between 0.02 and 0.1 mm/yr since circa 200 kyr. Trishear forward deformation modeling of the fold indicates that the amplification of the observed fold could be caused by two shallow thrusts formed through a break‐backward activation. This generated a decametric surface fold whose most recent growth was associated with bending‐moment normal faulting in the crestal and forelimb region. Our observations demonstrate that near‐surface compressive tectonics can be caused by blind thrusting, via a complex array of fault and folds: upward strain propagation and generation of shallow low‐angle thrust and related folding seem to be mainly due to secondary fold‐related faulting, according to an out‐of‐syncline thrusting mechanism.

Published: September 2014

AbstractA strategy has been developed for the regiospecific synthesis of 1‐trifluoromethylisoquinoline derivatives. This strategy is enabled by a photoredox vinyl isocyanide insertion with the help of Umemoto’s reagent. The methodology presented here provides an access to highly fuctionalized 1‐trifluoromethylisoquinolines regiospecifically under mild conditions in good‐to‐excellent chemical yields. A detailed mechanism is proposed, which is supported by experiments and theoretical calculations.magnified image
Heterogeneous Light‐Mediated Reductive Dehalogenations and Cyclizations Utilizing Platinum Nanoparticles on Titania (PtNP@TiO2)
Authors: McTiernan Christopher D. , Pitre Spencer P. , Ismaili Hossein , Scaiano Juan C. 
Published: September 2014

AbstractThe utility of platinum nanoparticles on titania (PtNP@TiO2) as a heterogeneous photoredox catalyst is evaluated using a series of reductive transformations. In comparison to TiO2 alone, TiO2 decorated with 0.2% PtNP shows enhanced efficiency, attributed to the NPs ability to both enhance light absorption and inhibit electron‐hole pair recombination. Herein, we demonstrate that under an inert atmosphere and UVA/visible light irradiation a system consisting of our PtNP@TiO2 catalyst in conjunction with a sacrificial electron donor [diisopropylethylamine, (i‐Pr)2NEt] can promote a variety of different reductive dehalogenations and cyclizations in moderate to excellent yields. In addition, the catalytic system is tolerant of many different functionalities and, due to its heterogeneous nature, holds the advantage of easy catalyst removal.magnified image

Published: September 2014

AbstractA three‐component alkoxycyanomethylation of alkenes is achieved using the iridium photoredox catalyst [fac‐Ir(ppy)3]. This catalytic radical difunctionalization accomplishes both alkylation and alkoxylation of alkenes in one pot. Various alcohols can serve as the alkoxy sources in this transformation. In addition, the introduced cyano group can undergo further transformations into various useful functional groups.magnified image
Cranial morphological diversity of early, middle, and late Holocene Brazilian groups: Implications for human dispersion in Brazil
Authors: Hubbe Mark , Okumura Mercedes , Bernardo Danilo V. , Neves Walter A. 
Published: September 2014

ABSTRACTThe history of human occupation in Brazil dates to at least 14 kyr BP, and the country has the largest record of early human remains from the continent. Despite the importance and richness of Brazilian human skeletal collections, the biological relationships between groups and their implications for knowledge about human dispersion in the country have not been properly explored. Here, we present a comprehensive assessment of the morphological affinities of human groups from East‐Central, Coastal, Northeast, and South Brazil from distinct periods and test for the best dispersion scenarios to explain the observed diversity across time. Our results, based on multivariate assessments of shape and goodness of fit tests of dispersion and adaptation models, favor the idea that Brazil experienced at least two large dispersion waves. The first dispersive event brought the morphological pattern that characterize Late Pleistocene groups continent‐wide and that persisted among East‐Central Brazil groups until recently. Within the area covered by our samples, the second wave was probably restricted to the coast and is associated with a distinct morphological pattern. Inland and coastal populations apparently did not interact significantly during the Holocene, as there is no clear signal of admixture between groups sharing the two morphological patterns. However, these results cannot be extended to the interior part of the country (Amazonia and Central Brazil), given the lack of skeletal samples in these regions.

Predation risk sensitivity and the spatial organization of primate groups: A case study using GIS in lowland Woolly Monkeys (Lagothrix lagotricha poeppigii)
Authors: Schmitt Christopher A. , Di Fiore Anthony 
Published: September 2014

ABSTRACTPredation risk is thought to be a potent force influencing intragroup cohesion, and the level of risk experienced by an individual is expected to vary with both group size and spatial position within a group. Smaller‐bodied and less‐experienced individuals are presumed to be more vulnerable to predators, suggesting that within‐group spatial organization should show size‐ and age‐dependent patterns in predator sensitive positioning. However, such effects have been difficult to evaluate for arboreal primates living in large groups. We conducted a preliminary study using a novel, spatially explicit method of assessing group spatial organization using GIS data in two groups of wild lowland Woolly monkeys, in which one group had a membership roughly twice as large as the second. In the larger group, group spread was more diffuse and large adult males were more frequently on the outskirts of the group than other age/sex classes, while immatures and females with dependents were more often in the center. Leaf cover around an individual—presumed to index an animal's perception of risk—increased significantly with distance from the group center for all immatures, although they were typically under lower leaf cover than adults; the number of groupmates in proximity also had an effect, but nearest neighbor distance did not. These differences were not detectable in the smaller group. This preliminary study suggests that thorough studies of spatial organization and predation risk sensitivity in arboreal primates are possible and could yield valuable information on how gregarious individuals offset ecological risks through social spacing.

Hexagonale Übergangsmetallchalkogenid‐Nanoflocken mit ausgeprägtem lateralen Quanten‐Confinement
Authors: Miró Pere , Han Jae Hyo , Cheon Jinwoo , Heine Thomas 
Published: September 2014

AbstractÜbergangsmetallchalkogenid(TMC)‐Nanoflocken der Zusammensetzung MX2(mit M=Ti, Zr und Hf; X=S und Se) kristallisieren bevorzugt in der Form gleichseitiger regelmäßiger Sechsecke und weisen ein ausgeprägtes Quanten‐Confinement auf. Die hexagonale Form von oktaedrischen (1T) TMC‐Nanoflocken ist das Ergebnis der Ladungslokalisierung an den Kanten und Ecken und der daraus resultierenden Coulomb‐Abstoßung. Größenunabhängig haben alle Nanoflocken die Zusammensetzung MnX2n−2und daher ein unoxidiertes Metallzentrum, was Dotierzustände hervorruft. Diese Zustände werden für kleine Nanoflocken relevant und führen zu deren metallischen Charakter, aber für größere Nanoflocken (>6 nm) dominieren die Eigenschaften der 2D‐Monolage. An die Kanten der Nanoflocken koordinierte Lewis‐Basen haben keinen wesentlichen Einfluss auf die elektronische Struktur dieser Spezies und bestätigen die Nützlichkeit der Kolloidsynthese.
