A distorção do conceito de economia no jornal Folha de São Paulo

The work aims to analyse the concept of economics as the science of scarcity is distorced in the newspaper Folha de Sao Paulo. Neoclassical economists characterize the economy as the science that is concerned with the welfare of the people, satisfying their needs. However, the economy in the newspapers of the mainstream media appears in contexts where only the profit of companies and businesses are addressed, leaving aside the problem of economic inequality, unemployment, working conditions and other issues that are also part of economy, but they are hardly concerns of journalists. In this work, the object of study was the notebook Market and content analysis followed the criteria of Bardin (1977). Ten words were chosen in the category science of scarcity and ten words were chosen in the category science of abundance. From these categories, a careful reading was done, counting how many times each word appeared in the newspaper. Also paid attention to the words that appeared and contexts in which they fell journalistic genre. In a second step, interviews were conducted with journalists from economics to know what they mean by the economy and what the guidelines are more common. Data collection and interviews contributed to the interpretation and confirmation on whether or not the distortion of the concept of economy and how it happens

Percepção da imagem corporal: comparação entre universitários do curso de educação física

The professional market for physical education and fitness demands for perfect and aesthetically beautiful bodies from its professionals, and the additional pressure of media, both add to the risk for body image dissatisfaction among these professional, increasing the risk for developing body image distortions and, ultimately, eating disorders. Body image dissatisfaction affects more women in their attempts for thin ideal. However, lately, because of social pressure for body aesthetical habits in both genders, men are faced with higher risk for distortions in body perception, leading to unhealthy eating habits and pathogenic exercise. With this in mind, the purpose of this study was to compare freshmen and senior physical education (PE) students from the State University of São Paulo (UNESP), as well as to make gender comparisons. Two groups comprise each, 46 freshmen PE students (23 females and 23 males), average age 18.7 ± 1.7 years; and 26 senior PE students (13 females and 13 males), average age 23 ± 1.9 years. Both groups filled out the questionnaires: Eating Attitudes Test/ EAT-26, Body Shape Questionnaire/ BSQ, Body Shape Questionnaire/ BSQ, and motivation state questionnaire/ LEA-RI. Results showed that the majority of participants wanted to change some aspect of their looks; women were more dissatisfied with their bodies than men; eating behavior scores were within the normal range for both groups. Finally, freshmen PE students are at a higher risk for body image distortion than senior PE students. We concluded that women, as well as younger individuals in general, are at higher risk for body image distortions. It is likely that experience in the further years of a physical education course has positive impact on body self image.

Construção da imagem corporal na fase pré-escolar

Schilder(1980) defines body image as the figuration of the body in your mind,ie to the way the body is presented to all. This image is constructed from six months in the infant´s contact with his mother by touch,thought the reflection of his image in the mirror and then in the contexto f activies préschool- didatic educator pedagogical proposes by consolidating the six years age. This importance of stdying the construction of body image pré-school educator is to prevent a failure in the process causing the child to change that image generating blocks and physical or psychological dificulties in the socialization process of children by promoting distortion of body image . O study objective is to understand how such package is the process of building up this image in preschool and your contribution to the process of learning of child. A methodology was a research review on amaig body, enconpassing the overall development of child and adult disorders the failure of the process constructive in this picture and a brief educational propose of how early childhood educator can work with this theme in pré-school. This study concluded that this topic is important to be working in the Field of education encompasses a degree in Physical Education and Pedagogy words.

Estudos estruturais por difração de raios X de fosfolipases A2 em presença de íons com importância funcional

Snakes from Bothrops genus are responsible for more than 90% of the ophidian accidents in Brazil. One of the main complications from this kind of accident is muscular necrosis, which is related to the action of phospholipases A2 and metalloproteases, two groups of enzymes found in the venom of these animals. Although this complication cannot be solved by serum therapy administration, a great number of studies have been performed with the attempt to know the pharmacological sites of these toxins aiming, in the future, the development of complementary treatments to serum therapy. This work proposes structural studies of bothropic phospholipases A2 (PLA2s) in the presence of ions relevant to their activity, using the X-ray crystallography technique. Recently, it was demonstrated ions, as manganese, calcium and others, interfere in the biological activity of the PLA2s. Particularly, Lys49-PLA2s in the presence of manganese ions have miotoxicity reduced. Asp49-PLA2s show catalytic activity dependent of calcium, although structural studies with a miotoxic Asp49-PLA2, BthTX-II, suggest a possible catalytic mechanism independent of calcium. Therefore, co-crystallization of BthTX-II in the presence of calcium ions and of PrTX-I in the presence of manganese ions were performed. Comparative structural studies among obtained results and others already published in the literature were performed aiming a better understanding of the structure-function relationship of these toxins. The BthTX-II with the presence of calcium do not show this ion in the loop of coordination of calcium, presence necessary to develop the catalyses. After comparison of this model with the native one, only one distortion was found, but no apparent relationship with the residues responsible for its activity. In the PrTX-I structure, regions candidates of manganese ions were also found... (Complete abstract click electronic access below)

Dielectric response of tungsten modified Ba(Ti0.90Zr0.10)O3 ceramics obtained by mixed oxide method

The electrical response of Ba(Ti0.90Zr0.10)O3 (BZT) ceramics obtained by the mixed oxide method as a functionof tungsten content was investigated. According to X-ray diffraction analysis the single phase BZT1W (1wt.% W doped BZT) and BZT2W (2 wt.% W doped BZT) ceramics, crystallized in a perovskite structure, wereobtained. It is also shown that tungsten substituted ceramics can be sintered at a reduced temperature whencompared to the undoped BZT. Electron paramagnetic resonance (EPR) analyses reveals that substitution ofTi4+ by W6+ causes distortion in the crystal structure changing lattice parameter. Substitution of W6+ on B-siteof ABO3 perovskite BZT ceramics shifted the phase transition to lower temperatures up to a tungsten contentof 2 wt.% leading to a relaxor-like behaviour.Keywords: donor dopant; ceramics; dielectric response; mixed oxide method

Do politicamente correto ao incorretamente polido

The text argues that a linguistic analysis paired with the appreciation of the context of current social stands is highly legitimate, observing, however, that, in different situations, this so-called investigative-appreciative attitude has been transformed in actions and reactions that might become vulgarized in common place, or might even become disfigured in stupidity. The distortions in the assessment of the discourse of the other are now a widespread, the hunt for what is now conventionalized as the politically incorrect in language is just a sample of such a distortion. In this presentation, a number of cases of such a nature is analyzed against cases in which, inversely, the use of language is markedly polite, but the deviation of conduct is made more evident. The objective is to evaluate both cases via the role of intersubjectivity in the construal of discourse, aiming at verifying its conceptual counterpart, with special attention to evidence on the mutual conceptual engagement between interlocutors.

External apical root resorption in retracted incisors

AIM: To evaluate the occurrence of external apical root resorption (EARR) in the incisors after anterior retraction in corrective orthodontic treatment with first premolar extractions and whether it was related with the type of root apex movement and its inclination. METHOD: The maxillary and mandibular incisors of 22 patients (12 to 25 years of age; 9 males and 13 females) were treated with fixed appliances and premolar extraction. EARR was defined as the difference in root length before and after incisal retraction on periapical radiographs. Distortion of radiographic images and changes due to incisal tipping were controlled for. Pre- and post-incisal retraction lateral cephalometric radiographs established the relationship between EARR and the tipping of the incisors, along with the vertical, horizontal, and total movement of the root apex. RESULTS: There was significant EARR (1.51 to 2.37 mm) during incisor retraction, but this was not related to the movement or the tipping of the root apex of almost all teeth. It was observed that after the retraction stage, EARR occurred in all evaluated incisors, but it was more significant (P < .05) in the mandibular right lateral incisor. CONCLUSION: The EARR that did occur was unrelated to movement or tipping of the root apex, except for the vertical root apex movement of the mandibular left central incisor and the inclination of the maxillary right lateral incisor.

Avaliação em modelos digitais das modificações ocorridas em modelos de gesso em função do posicionamento da moldeira

The objective of this study was to assess if the positioning of the impression tray could cause plaster casts distortion during gypsum setting time. fifteen pairs of master models were cast with alginate impression material and immediately poured with gypsum. impressions were allowed to set with the tray in the not inverted position (group a) or in the inverted position (group b). the plaster models were digitized using a laser scanner (3shape r-700, 3shape a/s). tooth size measurements and distances were obtained using o3d software (widialabs, brasil) measurement tools. data were analyzed by paired t test and linear regression with 5% significance. most measurements of both groups were similar, except for the lower intermolar distance. it was not possible to corroborate the presence of distortions owing to the position of the impression tray during gypsum setting time.

Reabilitação oral de paciente com síndrome da combinação: relato de caso

The Combination Syndrome represents an important pathologic condition of the masticatory system that requires a complex rehabilitation treatment. The presence of flaccid mucosa is one of the most common features due to bone resorption of the pre-maxilla caused by anterior hyperfunction of the mandibular teeth on the maxillary complete denture, where the impact of oclusal loading in this region results in movement of the maxillary prosthesis into the ridge, resulting in increased resorption of the residual ridge, internal misfit and loss of the retention of the maxillary complete denture. The presence of flaccid mucosa, in such cases, leads to problems of support and stability of the maxillary complete denture, which can be treated by surgical reduction of the thickness of the tissue or using specific techniques of fabrication of prostheses. This article describes the oral rehabilitation of a patient with the Combination Syndrome where the surgical reduction of flaccid mucosa was not performed, using a modified technique of functional impression in two steps, with the objective of generating forces and less distortion in flaccid mucosa during functional impression.
