Retratos de mulheres na literatura brasileira do século XIX

The aim of this article is to broaden our understanding of education and the concept of womanhood in the Brazilian society of the 19th century. On the basis of the analysis of a number of novels typical of the period it is concluded that novels had or intended to have a pedagogical function among the educated elite in the education of women. In this way, literature constituted an expression of a dominant and socially determined conception of womanhood and a pedagogical instrument that imposed social values.

Retratos da Espanha em Os fantasmas de Goya

1792, Madri. After years of inactivity, the Spanish Inquisition is born again with the mission of containing the laic winds that blow from the revolutionary France. Inês Bilbatúa, a rich merchant’s daugther, is victim of the inquisitorial machinery which tortures and violates her, through one of their abetters, the Dominican monk Lorenzo. Before being arrested, the young lady had served as model for the painter Francisco of Goya, who had also portrayed the monk Lorenzo. The Aragonese painter’s figure serves as narrative conductor of a history that narrates the young Inês’ via crucis and, at the same time, it recreates the historical scenery of the Napoleonic invasion (1808), through a basic element, the painting. Our work intends to analyze the relationships among movie, painting and history present in “Goya’s ghosts” (2006), of the Czech director Milos Forman (1932) - whose script was adapted to a homonymous book in 2007 -, a movie that is based on the artistic production of Francisco of Goya y Lucientes (1746 -1828), official painter of Carlos’ IV (1788 -1808) court and the most lucid columnist of his time, that knew how to capture in his works the religious fanaticism, the populist fervour, the governor’s hypocrisy and the horror and the violence of the war.

Retratos sociológicos: uma metodologia de investigação para a pesquisa em educação

Recently, Bourdieu’s sociological tradition has emerged as an important trend in research in science education. This paper presents some critiques elaborated by Bernard Lahire towards Bourdieu’s sociological approach. The main purpose of our incursion into Lahire’s critique is to argue and introduce the methodology of sociological portraits as an important resource for research in science education. After describing this methodology, it is illustrated with a portrait of dropout on an undergraduate course in chemistry. Diogo’s portrait illustrates, at the empirical level, some basic features of individual dispositions (variability, genesis, transferability, dichotomy and contextuality). From this portrait, it was possible to illustrate how the resonance between students’ and institution’s dispositions helps explain their sense of membership and belonging to the course. Finally, we highlight some potentialities of sociological portraits to the purposes of sociological research in science education.

Oxygen consumption by the hermit crab, Clibanarius vittatus (Bosc, 1802) in declining oxygen tensions

1. 1. Oxygen consumption and its relationship to stepwise declining oxygen tension were examined in the common striped hermit crab, Clibanarius vittatus. 2. 2. Weight-specific oxygen consumption varied with body weight (W), according to the equation log V ̇o2 = 2.1639 + (-0.419 log W). 3. 3. Shell-less individuals of 1-2 g wet wt, where found to be oxygen conformers, since oxygen consumption ( V ̇o2) decreased with declining oxygen tensions. At ambient oxygen tensions below 35.4 mmHg, oxygen consumption remained constant, suggesting an increased ventilation. 4. 4. C. vittatus was found to survive in oxygen-free seawater for 5.5 hr, and no significant differences were found in oxygen consumption rates, for shelled and shell-less crabs, measured in water and air. 5. 5. The use of a K1 K2 index of oxygen independence, showed that larger animals were better able to maintain oxygen-independence during hypoxia than smaller individuals. 6. 6. C. vittatus displayed a pattern of no oxygen debt, once returned to normoxia. © 1983.

Molecular barcode and morphological analyses reveal the taxonomic and biogeographical status of the striped-legged hermit crab species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802) (Decapoda: Diogenidae)

The taxonomic status of the species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802), which have sympatric biogeographical distributions restricted to the western Atlantic Ocean, is based only on differences in the colour pattern of the walking legs of adults. Their morphological similarity led to the suggestion that they be synonymised. In order to investigate this hypothesis, we included species of Clibanarius Dana, 1892 in a molecular phylogenetic analysis of partial sequences of the mitochondrial 16S rDNA gene and the COI barcode region. In addition, we combined the molecular results with morphological observations obtained from several samples of these two species. The genetic divergences of the 16S rDNA and COI sequences between C. sclopetarius and C. vittatus ranged from 4.5 to 5.9% and 9.4 to 11.9%, which did not justify their synonymisation. Differences in the telson morphology, chela ornamentation, and coloration of the eyestalks and antennal peduncle provided support for the separation of the two species. Another interesting result was a considerable genetic difference found between populations of C. vittatus from Brazil and the Gulf of Mexico, which may indicate the existence of two homonymous species.

Average control of Markov decision processes with Feller transition probabilities and general action spaces

This paper studies the average control problem of discrete-time Markov Decision Processes (MDPs for short) with general state space, Feller transition probabilities, and possibly non-compact control constraint sets A(x). Two hypotheses are considered: either the cost function c is strictly unbounded or the multifunctions A(r)(x) = {a is an element of A(x) : c(x, a) <= r} are upper-semicontinuous and compact-valued for each real r. For these two cases we provide new results for the existence of a solution to the average-cost optimality equality and inequality using the vanishing discount approach. We also study the convergence of the policy iteration approach under these conditions. It should be pointed out that we do not make any assumptions regarding the convergence and the continuity of the limit function generated by the sequence of relative difference of the alpha-discounted value functions and the Poisson equations as often encountered in the literature.

Low temperatures reduce skin healing in the Jacaré do Pantanal (Caiman yacare, Daudin 1802)

Studies of skin wound healing in crocodilians are necessary given the frequent occurrence of cannibalism in intensive farming systems. Air temperature affects tissue recovery because crocodilians are ectothermic. Therefore, the kinetics of skin wound healing in Caiman yacare were examined at temperatures of 33°C and 23°C. Sixteen caiman were selected and divided into two groups of eight maintained at 23°C or 33°C. The studied individuals' scars were photographed after 1, 2, 3, 7, 15 and 30 days of the experimental conditions, and samples were collected for histological processing after 3, 7, 15 and 30 days. Macroscopically, the blood clot (heterophilic granuloma) noticeably remained in place covering the wound longer for the caiman kept at 23°C. Microscopically, the temperature of 23°C slowed epidermal migration and skin repair. Comparatively, new blood vessels, labeled using von Willebrand factor (vWF) antibody staining, were more frequently found in the scars of the 33°C group. The collagen fibers in the dermis were denser in the 33°C treatment. Considering the delayed healing at 23°C, producers are recommended to keep wounded animals at 33°C, especially when tanks are cold, to enable rapid wound closure and better repair of collagen fibers because such lesions tend to compromise the use of their skin as leather.
