A fé contra o crime: A bakhtinian analysis of the image of evangelicals in Brazil in the cover of Veja magazine

The present paper, based on the concept of surplus of vision discussed in some works of the bakhtinian Circle, as, mainly Bakhtin (2010a) and Bakhtin (2010b), has the main aim to analyse the image of evangelicals in a cover delivered by Veja magazine from the bakhtinian categories of exotopy, otherness and expressive intonation and, consequently, the meaning effects resulting from them. Therefore, anchored by the perspective of Bakhtinian Studies (BS), we analysed the magazine cover, seeking to apprehend the meanings constructed by this genre of verb-visual basis. To the constitution of the corpus of analysis, we selected the cover of the edition 1555, published on July, 15, 1998, entitled A fé contra o crime: Numa cruzada em presídios e redutos de traficantes, os evangélicos estão convertendo bandidos em soldados de Jesus, to analyse in which way the magazine, from its discursive place, appropriates the image of the evangelicals and represents it with its intonations in its statements. From the analysis, we can state that Veja constructs an image that tends to the homogenization of the evangelicals in Brazil, from its surplus of vision, with its tone of sarcasm, prejudice and vilification of this group, attempting to position the consumer/reader of Veja against the protestant sphere. The conclusion of this research, therefore, is that the exotopic position assumed by Veja with regard to its otherness, the evangelical discursive sphere, articulates axiologic aprehensions materialized in the form of intonation on the cover of the magazine that we analysed, disseminating, with the character of truth, the protestant group as integrant of mere dualities. Although the cover figures the group as an agent of change in society, this change gets the intonation by the magazine so that it seems false or, at least, incomplete, which equips the Veja readers of mistrust and, therefore, discredit to the actions of the discussed discursive sphere.

THE SCHOOL TEXTUAL PRODUCTION PROCESS MEDIATED BY LINGUISTIC ANALYSIS WITH FOCUS ON ARGUMENTATION

It is showed in this text, discussion about the textual (re)writing process in activity that was propitiated through the development of a research project applied in a public school of Parana state, whose goal was to develop the argumentative writing production at the 9th year students, of the basic education. The research project focused on the teaching of a scientific paper and the use of conjunctions as constituent elements of argumentation. It was applied strategies grounded on Argumentative Semantics which were concerned with the conjunctions use as argumentative elements and, for the expansion of ideas. After the produced material analysis, it was selected this work’s corpus, which is constituted of the last version of the written text by one student whose production was well qualified. It was verified that the textual genre suggested and the conjunctions usage as argumentation organizer element was considered by the student, at the writing activities. 

Raman microscopy of formamide-intercalated kaolinites treated by controlled-rate thermal analysis technology

Raman spectroscopy of formamide-intercalated kaolinites treated using controlled-rate thermal analysis technology (CRTA), allowing the separation of adsorbed formamide from intercalated formamide in formamide-intercalated kaolinites, is reported. The Raman spectra of the CRTA-treated formamide-intercalated kaolinites are significantly different from those of the intercalated kaolinites, which display a combination of both intercalated and adsorbed formamide. An intense band is observed at 3629 cm-1, attributed to the inner surface hydroxyls hydrogen bonded to the formamide. Broad bands are observed at 3600 and 3639 cm-1, assigned to the inner surface hydroxyls, which are hydrogen bonded to the adsorbed water molecules. The hydroxyl-stretching band of the inner hydroxyl is observed at 3621 cm-1 in the Raman spectra of the CRTA-treated formamide-intercalated kaolinites. The results of thermal analysis show that the amount of intercalated formamide between the kaolinite layers is independent of the presence of water. Significant differences are observed in the CO stretching region between the adsorbed and intercalated formamide.

Detailed analysis of a conservative difference approximation for the time fractional diffusion equation

Diffusion equations that use time fractional derivatives are attractive because they describe a wealth of problems involving non-Markovian Random walks. The time fractional diffusion equation (TFDE) is obtained from the standard diffusion equation by replacing the first-order time derivative with a fractional derivative of order α ∈ (0, 1). Developing numerical methods for solving fractional partial differential equations is a new research field and the theoretical analysis of the numerical methods associated with them is not fully developed. In this paper an explicit conservative difference approximation (ECDA) for TFDE is proposed. We give a detailed analysis for this ECDA and generate discrete models of random walk suitable for simulating random variables whose spatial probability density evolves in time according to this fractional diffusion equation. The stability and convergence of the ECDA for TFDE in a bounded domain are discussed. Finally, some numerical examples are presented to show the application of the present technique.

Determination of preventive maintenance lead time using hybrid analysis

The time for conducting Preventive Maintenance (PM) on an asset is often determined using a predefined alarm limit based on trends of a hazard function. In this paper, the authors propose using both hazard and reliability functions to improve the accuracy of the prediction particularly when the failure characteristic of the asset whole life is modelled using different failure distributions for the different stages of the life of the asset. The proposed method is validated using simulations and case studies.

Hydrazine-hydrate intercalated halloysite under controlled-rate thermal analysis conditions

The thermal behaviour of halloysite fully expanded with hydrazine-hydrate has been investigated in nitrogen atmosphere under dynamic heating and at a constant, pre-set decomposition rate of 0.15 mg min-1. Under controlled-rate thermal analysis (CRTA) conditions it was possible to resolve the closely overlapping decomposition stages and to distinguish between adsorbed and bonded reagent. Three types of bonded reagent could be identified. The loosely bonded reagent amounting to 0.20 mol hydrazine-hydrate per mol inner surface hydroxyl is connected to the internal and external surfaces of the expanded mineral and is present as a space filler between the sheets of the delaminated mineral. The strongly bonded (intercalated) hydrazine-hydrate is connected to the kaolinite inner surface OH groups by the formation of hydrogen bonds. Based on the thermoanalytical results two different types of bonded reagent could be distinguished in the complex. Type 1 reagent (approx. 0.06 mol hydrazine-hydrate/mol inner surface OH) is liberated between 77 and 103°C. Type 2 reagent is lost between 103 and 227°C, corresponding to a quantity of 0.36 mol hydrazine/mol inner surface OH. When heating the complex to 77°C under CRTA conditions a new reflection appears in the XRD pattern with a d-value of 9.6 Å, in addition to the 10.2 Ĺ reflection. This new reflection disappears in contact with moist air and the complex re-expands to the original d-value of 10.2 Å in a few h. The appearance of the 9.6 Å reflection is interpreted as the expansion of kaolinite with hydrazine alone, while the 10.2 Å one is due to expansion with hydrazine-hydrate. FTIR (DRIFT) spectroscopic results showed that the treated mineral after intercalation/deintercalation and heat treatment to 300°C is slightly more ordered than the original (untreated) clay.
