O ritual de desmaterialização dos objetos singularizados e a transformação da relação pessoa-objeto

A transformação da sociedade nos últimos anos faz contraponto ao desejo de posse e acumulação física dos consumidores. A realidade digital abre inúmeras possibilidades de consumo e tem modificado a relação dos indivíduos com os objetos físicos e as posses materializadas. Consequentemente, vários pesquisadores de consumo (BELK, 2013; BARDHI et al., 2012; MAGAUDDA, 2011, 2012) têm se dedicado ao estudo ​​da desmaterialização (o desaparecimento físico dos objetos). Embora estudos anteriores avancem na pesquisa sobre a singularização do objeto e sua re-commoditização (EPP; PRICE, 2010), contextos e processos em que indivíduos desmaterializam suas posses singularizadas carecem de mais pesquisas. A desmaterialização até aqui foi observada como sinônimo de digitalização (BELK, 2013) ou a transformação de objetos físicos em virtuais (MAGAUDDA, 2011). Em contraste, o presente trabalho analisa a desmaterialização como transcendendo o mundo digital. A desmaterialização é vista como o processo de ver as posses desaparecendo fisicamente da vida dos consumidores por meio de doação, venda, descarte ou digitalização. A desmaterialização pode ser uma forma de distanciamento físico, mantendo o valor imaterial, garantindo o acesso, salvaguardando a singularidade do objeto, e protegendo-o da comoditização. A contradição entre a materialização física e a liquidez na sociedade nos abre um promissor campo de estudo por elucidar como o processo de afastamento das posses influencia as transformações dos indivíduos (ROSTER, 2014; CHERRIER, 2010; MAGAUDDA, 2011, 2012; MOLESWORTH; DENEGRIT-KNOTT, 2012). Para compreensão do fenômeno, foram realizadas 11 entrevistas existencial-fenomenológicas com colecionadores de livros em diferentes fases do processo de desmaterialização. A Abordagem hermenêutica foi usada para compreender como as pressões da sociedade contemporânea modificam a forma como as pessoas interagem com os objetos singularizados. A análise revelou que a relação pessoa-objeto entre colecionadores e seus livros é permeada por sonhos e desejos. Ela existe em um espaço liminar entre o real e o imaginário. Este espaço liminar que o livro físico ocupa na mente dos proprietários é o elo que permite a desmaterialização. O valor do livro vem da sua capacidade de possuir e transferir o conhecimento imaterial. A relação que colecionadores tem com seus livros é essencialmente emocional, principalmente devido ao valor imaterial. Mas, por outro lado, a ligação física é o que torna difícil o ritual de desmaterialização. Quando colecionadores desmaterializam uma coleção de livros, eles enfrentam seus valores relativos à materialidade, ao apego e ao passado, e vivenciam a possibilidade de compartilhamento e transformação da relação com os objetos e outros seres humanos. Assim, a desmaterialização pode ser considerada como uma continuação do processo de autoconhecimento que começou com os rituais de materialização. Esta descoberta tem implicações significativas para a compreensão da natureza experiencial do consumo para os indivíduos. O presente trabalho aprofunda a compreensão da relação pessoa-objeto e a transformação das relações que os indivíduos estabelecem com outros objetos e o mundo ao seu redor.

O ritual simbólico do Ctrl+C (copiar ) e Ctrl+V (colar) no ensino médio

Nowadays, technology has a direct influence on the relationship student and teacher have with language. The internet is a powerful tool in helping work with the language and, through it, the knowledge comes to the student easily and intensely. Furthermore, this facility has enhanced and made visible what has been called, within the University community, "plagiarism generation." This work assumes that this generation has, in their written texts, symbolic movements similar to those of "copy and paste" applied to research work carried out by high school students. Taking this as starting point, this dissertation aims to analyze how high school students of the 1st year from a school in Natal (RN) construct texts, under the movements known as "Ctrl + c" and "Ctrl + v", with reference to the text of the "other". More specific issues are behind the general objective, namely: 1. how the student appropriates the source-text when he copies and pastes? 2. What are the categories of analysis that allow us to look analytically and theoretically for the "ctrl + c / ctrl + v" practice made by the student? 2. how the studies developed in the fields of "Genetic Criticism" (Grésillon, 1987), the "school manuscripts" (Calil, 2004) and "paraphrase" (Fuchs, 1982) may help in working with writing in the classroom standing as a possible way to minimize the copy and paste effects in the students texts? Thus, we observe the categories of analysis that allow us to look, theoretically and analytically, for the symbolic ritual of the "ctrl + c" (copy) and "ctrl + v" (paste) in high school. Our study shows that the student text is a "hybrid body" whose writing is a drawing entanglement because of the presence of the foreign text, verbatim, and the presence of linguistic elements to paraphrase the original text.This textual embodiment has, behind it, certain operations, namely: replacing, moving, adding and deleting statements. Given the specificity of the data and the research objectives, this study aligns with qualitative research methods (SILVERMAN, 2009) and falls within the knowledge field of Applied Linguistics, which is characterized especially by investigating problems, phenomena in which language in a real situation is taken as central (BRUMFIT, 1995).Theoretically, our work follows the approach of studies on the paraphrase (Fuchs, 1982, 1994a, 1994b; DAUNAY, 1997, 1999, 2002a, 2002b), the studies developed in the field of Genetic Criticism (Grésillon, 1987, 1994, 1992, 2008 ) and those developed by Eduardo Calil (2004) on "school manuscripts"

Compreendendo a dança do Torém: visões de folclore, ritual e tradição entre os Tremembé do Ceará

Este artigo pretende discutir as mudanças históricas e culturais que têm afetado o torém, a dança específica mantida pelos Tremembé do estado do Ceará. Ainda que o torém tenha sido referido em registros históricos desde o século dezenove, ele tem sido objeto de apreciações e percepções diversas por muitos grupos sociais. Índios, pesquisadores, missionários e agentes do Estado têm tido diferentes posições, às vezes contraditórias, sobre a dança. Um de meus principais objetivos é entender como o torém tem sido progressivamente objetificado por idéias de folclore, etnicidade e política a partir dos contextos históricos específicos nos quais eles devem ser situados. Preocupações antropológicas sobre a experiência da etnicidade são relacionadas a elementos particulares da dança, especialmente os significados do vestuário, da música e da performance.

The end magnets of the IFUSP race-track microtron booster

The end magnets of the IFUSP race-track microtron booster, second stage of the electron accelerator under construction at the Linear Accelerator Laboratory, are presented. They deflect, focus and return the beam to the accelerating section. Details about the project are discussed, Poisson code was used to give the final geometry of the end magnets. The end magnets incorporate auxiliary pole pieces (clamps) which create a reverse fringe field region that avoids the beam vertical defocusing and reduces the horizontal displacement produced by extended fringe fields (EFF). The small gap height used for the clamps provided reverse field distributions with fringe fields of short extensions, avoiding the traditional use of inactive clamps. Measurements and calculations concerning particle trajectories and reverse field distribution are presented. The floating wire technique, employing an original procedure to register orbits, was used to corroborate the calculated beam trajectories and represents a good experimental option in the lack of the accelerator beam. The experimental results showed agreement of about 0.1% with the calculations.

The IFUSP race-track microtron booster accelerator end magnets antisymmetric perturbations

We will present measurements and calculations related to the antisymmetric perturbations, and comparisons with the symmetric ones, of the IFUSP race-track microtron booster accelerator end magnets. These perturbations were measured in planes situated at +/-12 mm of the middle plane, in a gap height of 4 cm, for a field distribution of about 0.1 T. The measurements were done in 1170 points, separated by a distance of 8 mm, using an automated system with a +/-1.5 mu T differential Hall probe. The race-track microtron booster is the second stage of the 30.0 MeV electron accelerator under construction at the Linear Accelerator Laboratory in which the required uniformity for the magnetic field is of about 10(-3). The method of correction employed to homogenize the IFUSP race-track microtron booster accelerator magnets assures uniformity of 10(-5) in an average field of 0.1 T, over an area of 700 cm(2). This method uses the principle of attaching to the pole pieces correction coils produced by etching techniques, with copper leads shaped like the isofield lines of the normal component of the magnetic field measured. The ideal planes, in which these measurements are done, are calculated and depend on the behavior of the magnetic field perturbations: symmetric or antisymmetric with reference to the middle plane of the magnet gap. These calculations are presented in this work and show that for antisymmetric perturbations there is no ideal plane for the correction of the magnetic field; for the symmetric one, these planes are at +/-60% of the half gap height, from the middle plane. So this method of correction is not feasible for antisymmetric perturbations, as will be shown. Besides, the correction of the symmetric portion of the field distribution does not influence the antisymmetric one, which almost does not change, and corroborates the theoretical predictions. We found antisymmetric perturbations of small intensity only in one of the two end magnets. However, they are not detected at +/- 1 mm of the middle plane and will not damage the electron beam.

Is the Thoroughbred race-horse under chronic stress?

Thoroughbred fillies were divided into three groups according to age: group 1, 7 fillies aged 1 to 2 years (G1) starting the training program; group 2, 9 fillies aged 2 to 3 years (G2) in a full training program; group 3, 8 older fillies 3 to 4 years of age (G3) training and racing. Blood samples were collected weekly from July to December. Cortisol was quantified using a solid phase DPC kit. The intra- and interassay coefficients of variation were 12.5% and 15.65% and sensitivity was 1.9 ± 0.2 nmol/ l. The semester average of cortisol levels varied between groups: G1 = 148.8 ± 6.7, G2 = 125.7 ± 5.8, G3 = 101.1 ± 5.4 nmol/l, with G3 differing statistically from the other groups. The lower cortisol levels observed in the older fillies leads us to propose that the stress stimulus, when maintained over a long period of time, may become chronic and result in a reduction of hypophyseal corticotropin-releasing hormone receptors. The secretion of endogenous opioids may also lead to low serum cortisol levels.

Evaluation of race distance, track surface and season of the year on exercise-induced pulmonary haemorrhage in flat racing Thoroughbreds in Brazil

Reasons for performing study: To our knowledge no studies evaluating risk factors to EIPH have been undertaken with such a population of horses in Brazil, which is one of the few countries in the racing community to accept the use of frusemide (FUR) as a prerace medication for bleeders. We also compared national results with those already in the literature. Objectives: To verify the influence of variables such as distance of the race, racetrack surface, going and season of the year in the recurrence and severity of EIPH and its effect on the finishing position of flat racing Thoroughbreds in Brazil. Methods: 2118 post race respiratory endoscopies were recorded, in a total of 1003 individual horses. All horses in the study were certified bleeders (deemed positive by registered veterinarians following one or more endoscopies) and were administered FUR prior to each race. Data was analysed using both ordinary logistic regression and multiple logistic regression. Results: The results suggest that race distance, season of the year and racetrack surface affect the recurrence of EIPH. Also, despite the use of FUR, the majority (62%) of horses continued to display some degree of haemorrhage. Conclusions: There was a tendency for horses that remained positive despite the use of FUR to finish unplaced in a race. Horses which had a significant reduction in bleeding and became HPIE negative after the use of FUR, tended to finish in top positions. It was not possible to determine a pattern of severity of EIPH in horses with more than one endoscopy. Further studies are required to improve our understanding of this syndrome and its correlations to performance in the racing Thoroughbred, together with the role of FUR and its possible enhancing performance effects and efficacy in consistently diminishing EIPH. Potential relevance: This study enabled a better understanding of the use of FUR in Brazilian Thoroughbred racehorses and showed there was a tendency towards improvement in performance after administrion of FUR in bleeders. The fact that a large number of horses remained positive for EIPH despite the use of FUR should encourage the scientific community to search for better ways of reducing, or preventing, this syndrome. © 2006 EVJ Ltd.

Performance of race instrumentation system in curved root canals: a comprehensive analysis by three study methods

In this study, curved maxillary molar root canals were instrumented with RaCe rotary system to evaluate: 1. the occurrence of canal transportation using a radiographic platform; 2. the action of the instruments on the dentin walls, centering ability and canal enlargement by analysis of digital images; and the percentage of regular dentin surfaces and debris within the canal by histological analysis. Ten mesiobuccal roots of extracted human maxillary molars were embedded in acrylic resin and sectioned at the middle and apical thirds. Root canal shaping was performed using the RaCe rotary system at 250 rpm and 1 Ncm torque. Each instrument set was used five times according to a crowndown technique in the following sequence: 40/0.10, 35/0.08, 25/0.06, 25/0.04, 25/0.02 (working length - WL), 30/0.02 (WL) and 35/0.02 (WL). Each instrument was inserted until resistance was felt and then pulled back, followed by brushing movements towards all canal walls. Each specimen was assessed by three study methods: radiographic platform, digitized image assessment and histological analysis. The radiographic platform showed lack of apical transportation. No statistically significant difference (Wilcoxon test, p>0.05) was found between the middle and apical thirds regarding instrument action on dentin walls, centering ability, area of root canal enlargement, percentage of regular dentin surfaces and debris within the root canal. It may be concluded that RaCe system is a suitable method for the preparation of curved root canals, regarding the maintenance of root canal original path, action on dentin walls, canal enlargement and removal of debris from the root canal lumen.

Ritual de consumo do crack: Aspectos socioantropológicos e repercussões para a saúde dos usuários

The use of crack cocaine has given rise to an intense discussion in society. Research has contributed to the characterization of users and the negative consequences of its use. However, few studies have conducted in-depth study of the social and cultural contexts in which crack cocaine is used. Thus, this study seeks to discuss the ritual of crack cocaine use and its social and health consequences for the user. It is a qualitative study developed in the Psychosocial Care Centers for Alcohol and Drugs (Portuguese acronym: Caps-ad). The individuals were selected in two groups of keyinformants: crack cocaine users undergoing treatment and health professionals. Data was obtained by means of semi-structured interviews. The results revealed that the use of crack cocaine is not dissociated with the current organizational structure of society. There is a link between the use of this substance and the social organization for its use. By using crack cocaine, the individuals try to be part of a consumer market, actively participating in what society perceives as new. The forms and locations of use are directly related to users' health, making it necessary for healthcare services to detect, approach and make health interventions in these locations of use.
