Tempo, memória e narrativa kaingang no oeste catarinense: a tradição kaingang e a proteção tutelar no contexto da transformação da paisagem na terra indígena Xapecó
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este estudo acerca dos Kaingang da Terra Indígena Xapecó orienta-se pelas relações estabelecidas do povo com o ambiente e seus desdobramentos, visa dessa forma apresentar os meandros da atuação da proteção tutelar no contexto da transformação da paisagem e as consequentes rupturas, impactos e/ou continuidades no modo de vida e no habitus social Kaingang. A temporalidade deste estudo conduziu-se a partir dos registros e descrições relacionadas aos Kaingang do século XVIII e alcança a contemporaneidade. Os encontros e desencontros dos Kaingang com não índios em terras meridionais foram registrados em descrições de cunho etnográfico e representam momentos decisivos na trajetória histórica do povo. Por outro lado, foi a partir dos oitocentos e, sobretudo, dos novecentos que a espacialização e a territorialidade Kaingang deslocaram-se visceralmente da condição de mobilidade para a de homo situs, impactando as relações do povo no tempo/espaço. A indigeneidade da paisagem marca as narrativas de história e memória dos Kaingang ressaltando a existência do tempo dos ?antigos? e do tempo de ?agora?. As reminiscências mnemônicas expressas entre silêncios, esquecimentos e lembranças descrevem os enredos das relações de contato e da proteção tutelar, bem como as instâncias constituintes do mundo Kaingang. As narrativas ressaltam o papel central do ?mato virgem? e do ?pinhalão? no modo de vida e no habitus social à medida que estes espaços são entendidos como elementos integrantes da tradição Kaingang. A tese elaborou e apresenta diversos produtos em história indígena e ambiental no que concerne a localização e a caracterização da TI Xapecó através de mapas e da perspectiva multi-temporal da composição da cobertura florestal. As sinuosidades da transformação do modo de vida e habitus social Kaingang e da paisagem da TI Xapecó são expressas nas múltiplas faces da proteção tutelar, que por meio do propulsor indigenismo brasileiro, possibilitou a grilagem, o esbulho e a espoliação dos índios do ?Chapecózinho? ao mesmo tempo em que a inserção da TI na lógica do desenvolvimento econômico. A ?marcha para a emancipação econômica? do Posto Indígena Xapecó a partir da gestão do patrimônio indígena percorreu momentos distintos e pautou-se na exploração das potencialidades naturais. O modelo de indigenismo rondoniano-varguista marcou um primeiro momento da proteção tutelar sendo procedido pelo indigenismo da FUNAI, que a despeito de seu início moralizante, permitiu à exaustiva exploração dos recursos florestais e inseriu as terrasindígenas no sul do Brasil no contexto do nacional-desenvolvimentismo brasileiro. A exploração da madeira se encerrou na TI Xapecó e a proteção tutelar na figura do chefe de Posto perdeu definitivamente qualquer status de poder centralizador à medida que o protagonismo Kaingang passou a conduzir as práticas políticas e socioeconômicas locais.Abstract : This study about the Kaingang of the Indigenous Land Xapecó is guided by the established relationships of the people with the environment and its consequences, aims to present the intricacies of the tutelary protection action in the context of the landscape transformation and the resulting disruptions, impacts and/or continuities in the way of the Kaingang life and social habitus. The temporality of this study was conducted from the records and descriptions related to the Kaingang of the eighteenth century and reach the contemporary. The meetings and missings of the Kaingang with non-Indians in southern lands were recorded in ethnographic descriptions and represent defining moments in the historical trajectory of the people. On the other hand, was from eight hundred and, especially, the nine hundreds that the Kaingang spatiality and the territoriality viscerally moved up from de mobility condition for the homo situs, impacting the relationships of the people in the time/space. The indigeneity of the landscape mark the narratives of memory and history of Kaingang highlighting the existence of time the "old" and the time of "now." The mnemonic reminiscences expressed between silences, omissions and memories describe the plots of contact relations and of tutelary protection, as well as the constituent bodies of the Kaingang world. The narratives emphasize the central role of the "virgin forest" and the "Pinhalão" on the way of life and social habitus as these spaces are seen as integral components of Kaingang tradition. The thesis developed and presents several products in indigenous and environmental history regarding the location and characterization of Indigenous Land Xapecó through maps and multi-temporal perspective of the composition of the forest cover. The sinuosity of the transformation of the Kaingang way of life and social habitus and the Indigenous Land Xapecó landscape are expressed in the multiple facets of tutelary protection, which through the Brazilian indigenous propellant movement, allowed the illegal occupation, the dispossession and the theft of the "Chapecozinho" Indians while the integration of Indigenous Land in the logic of economic development. The "march toward economic emancipation" of the Indian Post Xapecó from the management of Indian heritage come different times and was marked on the exploitation of natural potential. The model rondonian-varguist of indianism scored a first moment of tutelary protection being undertaken by the FUNAI indianism, which despite its moralizing beginning, allowed the plundering of forest resources and entered indigenous landsin southern Brazil in the context of the Brazilian national-developmentalism. The logging ended in Indigenous Land Xapecó and the tutelary protection in the image of the post headman definitely lost any power status as the Kaingang role began to conduct local political and socio-economic practices

The VISTA Carina Nebula Survey. I. Introduction and source catalog
No full textContext. The Carina Nebula is one of the most massive and active star-forming regions in our Galaxy and has been studied with numerous multiwavelength observations in the past five years. However, most of these studies were restricted to the inner parts (≲1 square-degree) of the nebula, and thus covered only a small fraction of the whole cloud complex. Aims: Our aim was to conduct a near-infrared survey that covers the full spatial extent (~5 square-degrees) of the Carina Nebula complex and is sensitive enough to detect all associated young stars through extinctions of up to A_V ≈ 6 mag. Methods: We used the 4m Visible and Infrared Survey Telescope for Astronomy (VISTA) of ESO to map an area of 6.7 square-degrees around the Carina Nebula in the near-infrared J-, H-, Ks-bands. Results: The analysis of our VISTA data revealed 4 840 807 individual near-infrared sources, 3 951 580 of which are detected in at least two bands. The faintest S/N ≥ 3 detections have magnitudes of J ≈ 21.2, H ≈ 19.9, and Ks ≈ 19.3. For objects at the distance of the Carina Nebula (2.3 kpc), our catalog is estimated to be complete down to stellar masses of ≈0.1 M☉ for young stars with extinctions of AV ≈ 5 mag; for regions in the brightest parts of the central nebula with particularly strong diffuse emission, the completeness limit is at slightly higher stellar masses. We describe the photometric calibration, the characteristics, and the quality of these data. VISTA images of several newly detected or yet rarely studied clusters in the outer parts of the Carina Nebula complex are presented. Finally, a list of stars with high proper motions that were discovered in our analysis is provided in an appendix. Conclusions: Our catalog represents by far the most comprehensive deep near-infrared catalog of the Carina Nebula complex. It provides a new basis for spatially complete investigations of the young stellar population in this important star-forming complex. Based on observations made with ESO Telescopes at the La Silla Paranal Observatory under programme ID 088.C-0117.The catalog (full Table 2) is only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/572/A116..
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Detection of new O-type stars in the obscured stellar cluster Tr 16-SE in the Carina Nebula with KMOS
No full textContext. The Carina Nebula harbors a large population of high-mass stars, including at least 75 O-type and Wolf-Rayet (WR) stars, but the current census is not complete since further high-mass stars may be hidden in or behind the dense dark clouds that pervade the association. Aims. With the aim of identifying optically obscured O- and early B-type stars in the Carina Nebula, we performed the first infrared spectroscopic study of stars in the optically obscured stellar cluster Tr 16-SE, located behind a dark dust lane south of Car. Methods. We used the integral-field spectrograph KMOS at the ESO VLT to obtain H- and K-band spectra with a resolution of R 4000 (5 Å) for 45 out of the 47 possible OB candidate stars in Tr 16-SE, and we derived spectral types for these stars. Results.We find 15 stars in Tr 16-SE with spectral types between O5 and B2 (i.e., high-mass stars with M 8 M), only two of which were known before. An additional nine stars are classified as (Ae)Be stars (i.e., intermediate-mass pre-main-sequence stars), and most of the remaining targets show clear signatures of being late-type stars and are thus most likely foreground stars or background giants unrelated to the Carina Nebula. Our estimates of the stellar luminosities suggest that nine of the 15 O- and early B-type stars are members of Tr 16-SE, whereas the other six seem to be background objects. Conclusions. Our study increases the number of spectroscopically identified high-mass stars (M8 M) in Tr 16-SE from two to nine and shows that Tr 16-SE is one of the larger clusters in the Carina Nebula. Our identification of three new stars with spectral types between O5 and O7 and four new stars with spectral types O9 to B1 significantly increases the number of spectroscopically identified O-type stars in the Carina Nebula
The Carina project. V. The impact of NLTE effects on the iron content
No full textWe have performed accurate iron abundance measurements for 44 red giants (RGs) in the Carina dwarf spheroidal (dSph) galaxy. We used archival, high-resolution spectra (R ~ 38, 000) collected with UVES at ESO/VLT either in slit mode (five RGs) or in fiber mode (39 RGs, FLAMES/GIRAFFE-UVES). The sample is more than a factor of 4 larger than any previous spectroscopic investigation of stars in dSphs based on high-resolution (R 65 38000) spectra. We did not impose the ionization equilibrium between neutral and singly ionized iron lines. The effective temperatures and the surface gravities were estimated by fitting stellar isochrones in the V, B - V color-magnitude diagram. To measure the iron abundance of individual lines we applied the LTE spectrum-synthesis fitting method using MARCS model atmospheres of appropriate metallicity. For the 27 stars for which we measured both Fe I and Fe II abundances, we found evidence of NLTE effects between neutral and singly ionized iron abundances. The difference is ~0.1 dex, on average, but steadily increases when moving from the metal-rich to the metal-poor regime. Moreover, the two metallicity distributions differ at the 97% confidence level. Assuming that the Fe II abundances are minimally affected by NLTE effects, we corrected the Fe I stellar abundances using a linear fit between Fe I and Fe II stellar abundance determinations. We found that the Carina metallicity distribution based on the corrected Fe I abundances (44 RGs) has a weighted mean metallicity of [Fe/H] = -1.80 and a weighted standard deviation of \u3c3 = 0.24 dex. The Carina metallicity distribution based on the Fe II abundances (27 RGs) gives similar estimates ([Fe/H] = -1.72, \u3c3 = 0.24 dex). The current weighted mean metallicities are slightly more metal-poor when compared with similar estimates available in the literature. Furthermore, when we restricted our analysis to stars with the most accurate iron abundances, ~20 Fe I and at least three Fe II measurements (15 stars), we found that the range in iron abundances covered by Carina RGs (~1 dex) agreed quite well with similar estimates based on high-resolution spectra; however, it is a factor of 2-3 smaller than abundance estimates based on the near-infrared calcium triplet. This finding supports previous estimates based on photometric metallicity indicators. \ua9 2012. The Astronomical Society of the Pacific. All rights reserved.Peer reviewed: YesNRC publication: Ye
The Carina Project IX: on hydrogen and helium burning variables
No full textWe present new multiband (UBVI) time-series data of helium burning variables in the Carina dwarf spheroidal galaxy. The current sample includes 92 RR Lyrae - six of them are new identifications - and 20 Anomalous Cepheids, one of which is new identification. The analysis of the Bailey diagram shows that the luminosity amplitude of the first overtone component in double-mode variables is located along the long-period tail of regular first overtone variables, while the fundamental component is located along the short-period tail of regular fundamental variables. This evidence further supports the transitional nature of these objects. Moreover, the distribution of Carina double-mode variables in the Petersen diagram (P1/P0 versus P0) is similar to metal-poor globulars (M15, M68), to the dwarf spheroidal Draco, and to the Galactic Halo. This suggests that the Carina old stellar population is metal-poor and affected by a small spread in metallicity. We use trigonometric parallaxes for five field RR Lyrae stars to provide an independent estimate of the Carina distance using the observed reddening free Period-Wesenheit [PW, (BV)] relation. Theory and observations indicate that this diagnostic is independent of metallicity. We found a true distance modulus of μ = 20.01 ± 0.02 (standard error of the mean) ± 0.05 (standard deviation) mag. We also provided independent estimates of the Carina true distance modulus using four predicted PW relations (BV, BI, VI, BVI) and we found: μ = (20.08 ± 0.007 ± 0.07) mag, μ = (20.06 ± 0.006 ± 0.06) mag, μ = (20.07 ± 0.008 ± 0.08) mag, and μ = (20.06 ± 0.006 ± 0.06) mag. Finally, we identified more than 100 new SX Phoenicis stars that together with those already known in the literature (340) make Carina a fundamental laboratory for constraining the evolutionary and pulsation properties of these transitional variables
