Imagens de Otto Maria Carpeaux: esboço de biografia
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este esboço de biografia procura citar algumas imagens de Otto Maria Carpeaux: construções biográficas de naturezas múltiplas, elaboradas em contextos, por atores e sob condições igualmente díspares. Está constituído a partir de uma visão crítica da História, o que permite que ?outras imagens?, fragmentárias e não monumentais, também tenham espaço. Em diálogo com o princípio da montagem, este esboço apresenta-se em duas partes. Na primeira, Imagens possíveis, estão citadas as imagens elaboradas em vida e post mortem acerca do austríaco-brasileiro que nasceu em Viena em 1900, se exilou no Brasil em 1939 e morreu no Rio de Janeiro, em 1978. Na segunda, Montagens possíveis, apresentam-se duas possibilidades de exercício biográfico: pela leitura alegórica do documentário O velho e o Novo (Otto Maria Carpeaux), entendido como instrumento de intervenção no contexto ditatorial brasileiro e de uma reelaboração biográfica concernentes às suas experiências europeias; e pelo Caderno de imagens críticas, registro dos encontros em Carpeaux pelo meio de imagens críticas produzidas a partir da cesura do presente.Abstract : This biographical sketch attempts to quote some images of Otto Maria Carpeaux: various types of biographical constructions, carried out in different contexts by disparate authors under conditions just as distinct. It stems from a critical view of history, allowing for ?other images? fragmented and non-monumental ? to share the space.In dialogue with the montage principle, this sketch has two parts. The first, Possible Images, quotes the images produced during and after the life of the Austrian-Brazilian, who was born in Vienna in 1900, went to Brazil in exile in 1939 and died in Rio de Janeiro in 1978. The second part, Possible Montages, presents two possibilities of a biographical exercise: through the allegorical reading of documentary O Velho e o Novo (Otto Maria Carpeaux), understood as an instrument of intervention in the Brazilian dictatorship context and as a biographical retelling of the author?s European experiences; and through my Scrapbook of Critical Images, a record of the encounters in Carpeaux through critical images produced from the caesura of the present
Time-of-Day Could Affect Cognitive Screening Performance in Older Patients with TIA and Stroke
Get PDF<b><i>Background and Purpose:</i></b> The impact of time-of-day on the cognitive performance of older patients with limited cognitive reserve after a transient ischemic attack (TIA) or stroke, and on short cognitive tests, such as the Montreal Cognitive Assessment (MoCA), is unknown. We retrospectively studied whether morning versus afternoon assessment might affect the classification of patients aged 70 or older as severe (SCI), mild (MCI), and no (NCI) cognitive impairment by the MoCA. <b><i>Methods:</i></b> Morning (12 p.m. or earlier) versus afternoon (later than 12 p.m.) proportions of SCI (MoCA score <20), MCI (MoCA score 25-20) and NCI (MoCA score ≥26) were compared in a cohort of patients aged ≥70, attending a rapid-access TIA/stroke clinic. <b><i>Results:</i></b> Of 278 patients, 113 (40.6%) were tested in the morning and 165 (59.4%) in the afternoon. The proportion with SCI was greater in the afternoon than in the morning (10.9 vs. 1.8%, respectively, <i>p</i> = 0.004), with no difference in age, education, diagnosis, disability, or vascular risk factors. <b><i>Conclusions:</i></b> Time-of-day appears to affect cognitive performance of older patients after they undergo TIA and minor stroke. If our cross-sectional findings are confirmed in cross-over studies with repeated testing, timing of assessments should be considered in clinical practice and in research studies.</jats:p

Monitoring of water quality inflow and outflow of a farm in Italian Padana plain for rice cultivation: a case study of two years
Get PDFRice cultivation requires a large use of pesticides and nutrients to control weed proliferation and improve production. The water quality of four neighboring rice fields located in the Lomellina area (Italian Padana plain) was monitored in this study along with the cultivation period (before, during, and after the period of planting), for two successive agricultural seasons (2015 and 2016). Two paddy fields were traditionally cultivated with wet-seeding and the other fields with dry-seeding. Eighteen sampling points were considered: eight points for surface water, two points for underground water, and eight points for porous cups with two different depths. In order to evaluate the goodness of the paddy field system to maintain unchanged the quality of the inflow with respect to the outflow water, three of the most used herbicides in Italian rice cultivation (imazamox, oxadiazon, and profoxydim) and other physical-chemical parameters were determined, namely biological oxygen demand after 5 days; chemical oxygen demand; total suspended solids; anionic surfactants; total hardness; total amount of phosphorus, nitrogen, and potassium; and heavy metal concentrations. In general, all the collected data confirmed that paddy fields did not contribute to worsen the environmental pollution. The different flooding techniques adopted in the fields did not highlight significant differences in concentrations of pesticides or metals. The pesticides reached their maximum concentration (of the magnitude order of few ng mL(-1)) on the day after the administration and on the day after the application in the adjacent field. A slight reduction of total As in grain was obtained adopting a dry period from steam elongation up to booting. From the collected data, it was possible to identify a general water flow direction in the paddy fields from north-west to south-east: this prevailing flow direction was useful to understand not only the diffusion of the pesticides and their degradation products in the fields but also that of the nutrients. Concerning nutrients, it was important not to activate a recirculation of the water in the field during the first 10 days from the administration, in order to avoid loss of nitrogen in the water vents or for percolation. Moreover, the monitoring of potassium concentration allowed to avoid the use of unnecessary potassic fertilization when there was already a high amount of this element in the paddy field derived from irrigation. However, all the investigated water quality parameters were under the limits fixed by the European regulation. In addition, the presence of seven unexpected compounds was identified by the nontarget approach in both campaigns in samples collected in the early summer period. Four of these emerging contaminants were identified as N, N-diethyl-meta-toluamide, tricyclazole, amidosulfuron, and one of the imazamox photodegradation products. Although the obtained low concentrations of oxadiazion, tricyclazole, and arsenic, in particular, justified a preexisting contamination of the water inflow or of the investigated paddy area, the obtained results supported the good quality of the paddy water outflow, confirming the rational use of the water resource and the correct use of agronomic practices
Diasporas and secessionist conflicts : the mobilization of the Armenian, Albanian and Chechen diasporas
Get PDFThis article examines the impact of diasporas on secessionist conflicts, focusing on the Albanian, Armenian and Chechen diasporas and the conflicts in Kosovo, Karabakh and Chechnya during the 1990s. How do diasporas radicalize these conflicts? I argue that despite differences in diaspora communal characteristics and the types of the secessionist conflicts, a common pattern of mobilization develops. Large-scale diasporic support for secessionism emerges only after independence is proclaimed by the local elites. From that point onwards diasporas become engaged in a conflict spiral, and transnational coalitions are formed between local secessionist and diaspora groups. Depending on the organizational strength of the local strategic centre and the diasporic institutions, these coalitions endure or dissipate. Diasporas exert radicalization influences on the conflict spiral on two specific junctures – when grave violations of human rights occur in the homeland and when local moderate elites start losing credibility that they can achieve the secessionist goal

ESCRAVIDÃO E PATRIARCADO NA FICÇÃO DE MARIA FIRMINA DOS REIS | SLAVERY AND PATRIARCHY IN MARIA FIRMINA DOS REIS’ FICTION
Get PDFResumo: Primeira afrodescendente a publicar um romance no Brasil e, possivelmente, em toda a América Latina; e primeira autora de romance abolicionista na língua portuguesa, Maria Firmina dos Reis (1822-1917) antecipa em muitos aspectos a Negritude do século XX. Em Úrsula (1859), além de subverter a doxa ocidental que relegava o negro à condição de ser infrahumano, a autora articula a interseção entre gênero e etnicidade, a fim de representar patriarcado e escravidão como faces da mesma moeda. O presente trabalho relaciona a autora ao surgimento das narrativas da diáspora negra nas Américas e busca refletir sobre sentido e a importância do romance na literatura brasileira do século XIX. Abstract: First Afrodescendant woman to publish a novel in Brazil and, possibly, in all Latin America; and first author of an abolitionist novel in the Portuguese language, Maria Firmina dos Reis (b: 1822- d: 1917) anticipates in many aspects the “Negritude” of the twentieth century. In Ursula (1859), in addition to subverting the Western common belief that relegated the Colored to the condition of a subhuman being, the author articulates the intersection between gender and ethnicity in order to represent patriarchy and slavery as sides of the same coin. The present work relates the author to the emergence of the narratives of the black diaspora in the Americas and attempts to reflect on the meaning and importance of this novel in the Brazilian literature of the nineteenth century.
