Contrapunteos de Lydia Cabrera
No full textEven today in the history of Cuban anthropology, little attention is paid to the writer and anthropologist Lydia Cabrera, who has only recently begun to be part of the list of intellectuals in official Cuban culture. However, because of her work and life trajectory, Cabrera can be considered the modern founder of studies on Afro-Cuban religions.
The main purpose of this text is to analyse Lydia Cabrera’s ethnographic work based on the idea that there was a ‘counterpoint’, a dialogue, a metaphorical game, between the liminal identity of the author herself – manifested in a racial, cultural, gender, social and political sense – and her interest and dedication to the contribution of slaves and the population of African origin to the history, culture and, ultimately, the identity of their Cuban homeland.Todavía hoy en la historia de la antropología cubana se presta poca atención a la escritora y antropóloga Lydia Cabrera, quien solo muy recientemente ha empezado a formar parte de la nómina intelectual de la cultura cubana oficial. Sin embargo, en función de su obra y trayectoria vital puede considerarse a Cabrera como la fundadora moderna de los estudios sobre las religiones afrocubanas.
El objeto central de este texto es analizar el trabajo etnográfico de Lydia Cabrera a partir de la idea de que existe un contrapunteo, un diálogo, un juego metafórico, entre la identidad liminar de la propia autora -manifiesta en un sentido racial, cultural, de género, social y político- y su interés y dedicación a la aportación de los esclavos y la población de origen africano a la historia, a la cultura y, en última instancia, a la identidad misma de su patria cubana
Holopothrips tabebuia Cabrera & Segarra
No full textHolopothrips tabebuia Cabrera & Segarra (Figs 262–265) Holopothrips tabebuia Cabrera & Segarra, 2008: 232. Diagnostic features. Body mostly yellow, with head and pterothorax light brown, abdominal segments VIII–X dark brown; maxillary stylets parallel; one pair of long setae on epimeral region; metanotal sculpture formed by longitudinally elongate reticles, looking almost striate anteriorly; males with pore plates on sternites VII–VIII, two anteroangular plates and one posterior transverse band; female spermatheca s-shaped and not enlarged. Comments. This species resembles H. inquilinus in general appearance, but H. tabebuia has the pronotum with only one pair of long epimeral setae instead of two pairs (Fig. 262), and its metanotum is sculptured with longitudinal and narrow reticles (Fig. 263). The transverse pore plate on sternite VIII is prolonged onto the tergite as in H. inversus and H. paulus. Larvae are pale and without red internal pigmentation. Recently introduced into Florida, H. tabebuia is a common species in the Northern Caribbean, where it possibly originated (Cabrera & Segarra 2008). It has been observed inducing leaf-curling galls in a few Tabebuia (Bignoniaceae) species (Fig. 15), and in some cases, causing the death of young plants (Malumphy & Reid 2017). Material studied. 1 male non-type; United States, Florida, Dade, Hialeah, 7925 NW 2nd Ct., in Tabebuia sp., 20.ii.2002 (Davis, L.), slide with code “E2002-0692”; 1 female non-type; United States, Florida, Dade, Miami, 7061 SW 129th Ave., in Tabebuia sp., 4.iii.2002 (Putland, E.), slide with code “E2002-0691”; both at NMNH.Published as part of Lindner, Mariana F., Ferrari, Augusto, Mound, Laurence A. & Cavalleri, Adriano, 2018, Holopothrips diversity-a Neotropical genus of gall-inducing insects (Thysanoptera, Phlaeothripidae), pp. 1-99 in Zootaxa 4494 (1) on pages 86-88, DOI: 10.11646/zootaxa.4494.1.1, http://zenodo.org/record/144518
Comparative analysis of spread‐F signature and GPS scintillation occurrences at Tucumán, Argentina
No full textWe analyze data recorded from October 2010 to September 2011, during the ascending phase of the 24th solar cycle, from an Advanced Ionospheric Sounder-Istituto Nazionale di Geofisica e Vulcanologia ionosonde and a GPS Ionospheric Scintillation and total electron content (TEC) monitor scintillation receiver, colocated at low latitude in the Southern American longitudinal sector (Tucumán, 26.9°S, 294.6°E, magnetic latitude 15.5°S,Argentina). The site offers the opportunity to perform spread-F and GPS scintillation statistics of occurrence under the southern crest of the equatorial ionospheric anomaly. Spread-F signatures, classified into four types (strong range spread-F (SSF), range spread-F,frequency spread-F (FSF), and mixed spread-F), the phase and amplitude scintillation index (σΦ and S4, respectively), the TEC, and the rate of TEC parameter, marker of the TEC gradients, that can cause scintillations, are considered. The seasonal behavior results as follows: the occurrence of all four types of spread-F is higher in summer and lower in winter, while the occurrence of scintillations peaks at equinoxes in the postsunset sector and shows a minimum in winter. The correspondence between SSF and scintillations seems to be systematic, and a possible correlation between S4 and FSF peaks is envisaged at the terminator. The investigation focused also on two particular periods, from 12 to 16 March 2011 and from 23 to 29 September 2011, both characterized by the simultaneous presence of SSF signatures and scintillation phenomena, allowing to discuss the role of traveling ionospheric disturbances as a strong candidate causing ionospheric irregularities.Fil: Alfonsi, L..

Distribución y aspectos poblacionales del lobo Ibérico en la provincia de Ourense
No full textPara determinar el área de distribución del lobo en la provincia de Ourense (noroeste de España) se realizaron prospecciones de campo consistentes en itinerarios de muestreo para localizar indicios y se enviaron cuestionarios a los Agentes del Servicio de Conservación de la Naturaleza de la Xunta de Galicia y a las Sociedades de Cazadores del área de estudio. Los resultados se registraron sobre cuadrículas U.T.M. 10x10 Km. Se constata presencia del lobo en el 79,2% de las cuadrículas estudiadas, estimando el área de distribución en la provincia en 6.400 km2. Para la localización de los grupos familiares inicialmente se prospectó el territorio a nivel de cuadrículas U.T.M. 10x10 Km y en función de los resultados y la información recibida se eligieron determinadas zonas para realizar estaciones de escucha y espera. Determinamos durante el periodo de estudio la existencia de 25 grupos familiares. La densidad estimada en la provincia es de 2,10 – 3,28 lobos /100 km2. De los casos de mortalidad conocidos entre enero de 1999 y abril de 2002 (n=37), un elevado porcentaje se debió a atropellos (70,27%) principalmente en dos vías concretas y un 8,10% correspondió a envenenamientos. Actualmente la densidad del lobo en Ourense es superior a la obtenida en provincias limítrofes, pero amenazas de origen antrópico tanto directas (veneno, persecución ilegal...) como indirectas (incendios forestales, grandes infraestructuras viales, parques eólicos...) pueden estar condicionando la existencia de grupos familiares e incluso la presencia de la especie en determinadas zonas

Xirú e “Abaporu” de Damián Cabrera: configurações do “comum” da comunidade / Xirú and “Abaporu” by Damián Cabrera: Community “Common” Settings
No full textResumo: O estudo discute o “comum” (ESPOSITO, 2012; NANCY, 2000) a partir do livro Xirú e do conto “Aboporu” de Damián Cabrera, autor cuja escrita encontra-se pautada nas relações Brasil-Paraguai. Nestas obras estão colocadas em evidência a crise de uma concepção essencialista de comunidade, dada e/ou determinada previamente e o distanciamento do “paradigma moderno imunitário” (ESPOSITO, 2012) que se impõe contra qualquer convivência ou contágio que afete a pretensa pureza da comunidade. Sendo a língua um elemento inerente ao pensamento comunitário, parte-se, também, de certa perspectiva “translingue” (MELLO & ANDRADE, 2019) utilizada pelo autor e que expõe os contatos entre as línguas e as interferências como continuum naturais, transitórios, imprevistos que se articulam nas relações entre estas culturas e não como substâncias dadas previamente.Não menos importante, neste sentido, é a antropofagia manifesta no conto “Abaporu”, uma antropofagia nada ufanista pois, como a perspectiva “translingue” que manifesta Xirú, não é identitária e sim, como têm apontado as leituras contemporâneas que dela fazem Alexandre Nodari (2011), Florencia Garramuño (2019) e Eduardo Sterzi (2017), uma antropofagia como experimentação da diversidade, e com ênfase em uma posição relacional. Desse modo, o “comum” nestas obras se constitui como aquilo que não é próprio à comunidade, como substâncias que se compartilham, mas como laço relacional.Palavras-chave: Damián Cabrera; comum; translinguismo; antropofagia.Abstract: The study discusses the “common” (ESPOSITO, 2012; NANCY, 2000) based on the book Xirú and the short story Aboporu by Damián Cabrera, an author whose writing is based on Brazil-Paraguay relations. These works highlight the crisis of an essentialist conception of community, given and/or determined in advance, and the distancing from the “immunitarian modern paradigm” (ESPOSITO, 2012) that imposes itself against any coexistence or contagion that affects the alleged purity of the community. Since language is an inherent element of community thinking, it also starts from a certain “translingual” perspective (MELLO & ANDRADE, 2019) used by the author and which exposes contacts between languages and interferences as a natural, transitory, unforeseen continuum that are articulated in the relations between these cultures and not as previously given substances. No less important, in this sense, is the anthropophagy manifested in the short story “Abaporu”, an anthropophagy that is far from boastful because, like the “translingual” perspective that manifests Xirú, it is not identity but, as pointed out by contemporary readings made by Alexandre Nodari (2011), Florencia Garramuño (2019) and Eduardo Sterzi (2017), an anthropophagy as an experimentation with diversity, and with an emphasis on a relational position. In this way, the “common” in these works is constituted as what is not proper to the community, as substances that are shared, but as a relational bond.Keywords: Damián Cabrera; common; translingual; anthropophagy
