Do imaginário para a literatura: a confusão feminina na mentalidade do cristianismo europeu | From the Imaginary to Literature: female confusion in the mentality of European Christianity

Foi graças à perpetuação de certos preceitos de feminilidade que uma mentalidade antifeminina vingou no imaginário do cristianismo primitivo, enraizando-se na cultura europeia e revelando-se nas demonstrações de arte e literatura desde o baixo-medievo. Neste artigo busca-se discorrer sobre uma importante parte dessa maneira de pensar – a associação do feminino a um estado confuso ou à propagação da confusão, seja através da fala ardilosa ou da simples exposição à presença do feminino, que, para o cristianismo primitivo, estava intimamente ligado ao pecado original e à Queda. Dessa maneira, tenciona-se demonstrar como uma mentalidade antifeminina transpassou para a representação literária de feminino e de amor na Europa medieval, apresentando-se em cantigas e trovas variadas.Palavras-chave: Imaginário.

AbstractIt was due to the perpetuation of certain precepts of femininity that an anti-feminine mentality took hold in the imagination of primitive Christianity, taking root in European culture and revealing itself in art and literature demonstrations since the low-medieval period. This paper seeks to discuss an important part of this way of thinking – the association of the feminine with a confused state or the spread of confusion, whether through cunning speech or through simple exposure to the presence of the feminine, which for early Christianity was closely linked to the original sin and the Fall. This paper seeks, then, to demonstrate how an anti-feminine mentality was transferred to the literary representation of the feminine and of love in medieval Europe, presenting itself in different lyrics and songs.Keywords: Imaginary.

Empirical Evidence for Latitude and Altitude Variation of the In Situ Cosmogenic 26Al/10Be Production Ratio

We assess if variations in the in situ cosmogenic 26Al/10Be production ratio expected from nuclear physics are consistent with empirical data, knowledge critical for two-isotope studies. We do this using 313 samples from glacially transported boulders or scoured bedrock with presumed simple exposure histories in the Informal Cosmogenic-nuclide Exposure-age Database (ICE-D) from latitudes between 53°S to 70°N and altitudes up to 5000 m above sea level. Although there were small systematic differences in Al/Be ratios measured in different laboratories, these were not significant and are in part explained by differences in elevation distribution of samples analyzed by each laboratory. We observe a negative correlation between the 26Al/10Be production ratio and elevation (p = 0.0005), consistent with predictions based on the measured energy dependence of nuclear reaction cross-sections and the spatial variability in cosmic-ray energy spectra. We detect an increase in the production ratio with increasing latitude, but this correlation is significant only in a single variate model, and we attribute at least some of the correlation to sample elevation bias because lower latitude samples are typically from higher elevations (and vice versa). Using 6.75 as the 26Al/10Be production ratio globally will bias two-isotope results at higher elevations and perhaps higher latitudes. Data reported here support using production rate scaling that incorporates such ratio changes, such as the LSDn scheme, to minimize such biases.

Current trends and orientations in learning foreign languages

This article deals with the problem of effective learning of modern languages. We aim to point out the current, progressive guidelines on language learning followed by their actual use in various cultural contexts. Spontaneous, instinctive and natural learning, through simple exposure to the target language, is a current trend in learning modern languages, because a language is easier to learn in real, concrete contexts, hearing, speaking, participating.

Assessment of a New Antigen Detection Test for the Diagnosis of Canine Visceral Leishmaniasis

Canine visceral leishmaniasis (CVL) is a serious zoonotic disease in Brazil and Southern Europe. CVL is primarily caused by Leishmania infantum and its diagnosis relies primarily on detection of parasites in bone marrow or lymph node aspirates by microscopic observation of the parasites in stained smears, parasite culture, or polymerase chain reaction (PCR). Serological tests exist but they do not distinguish active disease from simple exposure to parasite antigens. Here, we have assessed the utility of a new monoclonal antibody––based antigen (protein) detection test for the diagnosis of CVL. The test was positive in 70% of beagle dogs experimentally infected with L. infantum. In contrast, culture of the parasites from bone marrow aspirates was positive in only 40% of the infected animals. These preliminary results suggest that this antigen detection test, which we have recently described for the diagnosis of human VL, has the potential to be a useful diagnostic tool for CVL.

The Presence of Absence: Why Does the Post-contact Rock Art of Torres Strait (Northeastern Australia) Not Include Paintings of European Ships?

Studies into the presence and absence of post-European contact rock art within Indigenous communities are particularly relevant to questions of colonial impact and influence. However, it is the presence of post-contact motifs and introduced subject matter that typically takes precedence in these studies. In this paper, we focus on the absence of post-contact paintings of European ships in Torres Strait (northeastern Australia) rock art. This absence is curious, given that Torres Strait peoples first encountered European ships over 400 years ago, yet the only paintings of watercraft are of their own double outrigger canoes. Furthermore, ethnographic information suggests many painted canoes were spirit canoes used by spirits of the dead, and European mariners were considered spirits of the dead who travelled in ‘ghost ships’. Despite apparent epistemological and ontological congruence between Islander and Kaurareg canoes and European ships, we argue the latter were conceptually and metaphysically different to spirit canoes and thus fell outside of the representational (rock art) genre of watercraft that was limited to spirit canoes. The lack of Torres Strait post-contact rock art reveals that reasons for the inclusion of introduced subject matter in post-contact rock art are likely to extend beyond simple exposure to, and familiarity with, so-called new subject matter.

Integrated approaches for the assessment of health impacts of environmental chemicals: our experience in the GraMo cohort study

The assessment of the health implications of human exposure to low doses of multiple environmental chemical pollutants represents an important challenge for environmental epidemiology. Current studies must go beyond simple exposure-disease associations and need further characterization of a complete exposure disease continuum, including exposure routes, adverse outcome pathways, potential subclinical effects, interactions between chemicals, and intra-individual susceptibility. This needs an effective synergism with basic sciences, which can enrich epidemiologic findings with very detailed information at a molecular level, but also with clinicians, who would help to provide accurate diagnoses and interpretation in a real-world scenario. On the other hand, environmental exposures can affect the general population at different levels, including economic and social dimensions, which have been frequently overlooked. These approaches would require specific methodologies that are relatively novel in the field of environmental epidemiology, such as cost-benefit analyses and qualitative techniques. Public health campaigns can clearly benefit from these mixed approaches.

Tuning the Linear and Nonlinear Optical Properties of Pyrene-Pyridine Chromophores by Protonation and Complexation to d10 Metal Centers †

The linear and second-order nonlinear optical (NLO) properties of two pyrene-pyridine chromophores, namely, 4-(pyren-1-yl)pyridine (L1) and 4-(2-(pyren-1-yl)ethyl)pyridine (L2), were investigated and modulated by performing protonation/deprotonation cycles or by complexation to d10 metal centers such as Zn(II) and Cu(I) to form the monomeric [Zn(CH3CO2)2(L1)2] complex and the [CuI(L2)]n coordination polymer, respectively. The structures of L1, L2, [Zn(CH3CO2)2(L1)2] and [CuI(L2)]n were determined by means of single-crystal X-ray diffraction studies. The NLO response, measured by the electric-field-induced second harmonic generation (EFISH) technique, was positive for both chromophores and showed an inversion of the sign after exposure to HCl vapors. This process was completely reversible and the original values were restored by simple exposure to NH3 vapors. Coordination of L1 to Zn(II) also resulted in a negative NLO response, although smaller in magnitude compared to the protonated form, due to the weak Lewis acidity of the “Zn(CH3CO2)2” fragment. The results were also interpreted on the basis of DFT/TDDFT calculations.

Why Asplenic Patients Should Not Take Care of the Neighbour’s Dog? A Fatal Course ofCapnocytophaga canimorsusSepsis

Capnocytophaga canimorsus(CC) belongs to the family Flavobacteriaceae which physiologically occurs in the natural flora of the oral mucosa of dogs and cats. In patients with a compromised immune system, CC can induce a systemic infection with a fulminant course of disease. Infections with CC are rare, and the diagnosis is often complicated and prolonged. We describe a patient with a medical history of prior splenectomy who presented with an acute sepsis and disseminated intravascular coagulation (DIC) and was initially treated on Waterhouse–Friderichsen syndrome (WFS). After the patient had died despite forced treatment in the intermediate care unit, the differential diagnosis of CC was confirmed by culture of blood smears. Later on, a retrospective third-party anamnesis revealed that the patient had contact to his neighbour’s dog a few days before disease onset. In conclusion, patients with CC infection can mimic WFS and therefore must be included in the differential diagnosis, especially in patients with a corresponding medical history of dog or cat bites, scratches, licks, or simple exposure.

It is magic! How impossible solutions prevent the discovery of obvious ones?

When confronted with an insight problem, some factors limit our capacity to discover the optimal solution. Previous research on problem solving has shown that the first idea that comes to participants’ minds can inhibit them from finding better alternative solutions. We used a magic trick to demonstrate that this mind fixing effect is more general than previously thought: a solution that participants knew to be incorrect and impossible inhibited the discovery of an easy alternative. We show that a simple exposure to an obvious false solution (e.g., the magician hides the card in the palm of his hand to secretly transfer it to his back pocket) can inhibit participants from finding the real secret of the trick (e.g., he used a duplicate card), even if the magician proves that this false solution is impossible (e.g., he shows his hand is empty). We discuss the psychological processes underlying this robust fixing effect.

Heteroaromatic Construction: The Li Synthesis of Mycoleptodiscin A

Kyungsoo Oh of Chung-Ang University cyclized (Org. Lett. 2015, 17, 450) the chloro enone 1 with NBS to the furan 2. Hongwei Zhou of Zhejiang University acylated (Adv. Synth. Catal. 2015, 357, 389) the imine 3, leading to the furan 4. H. Surya Prakash Rao of Pondicherry University found (Synlett 2014, 26, 1059) that under Blaise conditions, exposure of 5 to three equivalents of 6 led to the pyrrole 7. Yoshiaki Nishibayashi of the University of Tokyo and Yoshihiro Miyake, now at Nagoya University, prepared (Chem. Commun. 2014, 50, 8900) the pyrrole 10 by adding the silane 9 to the enone 8. Barry M. Trost of Stanford University developed (Org. Lett. 2015, 17, 1433) the phosphine-mediated cyclization of 11 to an intermediate that on brief exposure to a Pd catalyst was converted to the pyridine 12. Nagatoshi Nishiwaki of the Kochi University of Technology added (Chem. Lett. 2015, 44, 776) the dinitrolactam 14 to the enone 13 to give the pyridine 15. Metin Balci of the Middle East Technical University assembled (Org. Lett. 2015, 17, 964) the tricyclic pyridine 18 by adding propargyl amine 17 to the aldehyde 16. Chada Raji Reddy of the Indian Institute of Chemical Technology cyclized (Org. Lett. 2015, 17, 896) the azido enyne 19 to the pyridine 20 by simple exposure to I2. Björn C. G. Söderberg of West Virginia University used (J. Org. Chem. 2015, 80, 4783) a Pd catalyst to simultaneously reduce and cyclize 21 to the indole 22. Ranjan Jana of the Indian Institute of Chemical Biology effected (Org. Lett. 2015, 17, 672) sequential ortho C–H activation and cyclization, adding 23 to 24 to give the 2-substituted indole 25. In a complementary approach, Debabrata Maiti of the Indian Institute of Technology Bombay added (Chem. Eur. J. 2015, 21, 8723) 27 to 26 to give the 3-substituted indole 28. In a Type 8 construction, Nobutaka Fujii and Hiroaki Ohno of Kyoto University employed (Chem. Eur. J. 2015, 21, 1463) a gold catalyst to add 30 to 29, leading to 31.
