Traduzindo o economês: metáforas da inflação em textos de jornalismo econômico

The research aimed two objectives: 1st) identifying and describing the metaphors of the inflation, in a corpus of 18 texts of economic journalism, from Joelmir Beting, written in the last trimester of 2002, at the moment of the government s transition of president Fernando Henrique Cardoso to Luiz Inácio Lula Da Silva. 2nd) verifying the recognition of the metaphors by the students of the basic education of a private school from Natal. 91 metaphors had been identified, analyzed in the perspective of the conceptual metaphor s theory, by Lakoff and Johnson (2002), on the basis of the distinction between conceptual metaphor and metaphoric expressions, and between domain-source/domain-target. 10 underlying conceptual metaphors had been inferred, being that the domains-source used more frequently to characterize the inflation had been those ones according to the human being and the animals and, of a less imaginable form, to the ways of transport (car, aircraft). These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements

Effects of buprenorphine, carprofen and saline on thermal and mechanical nociceptive thresholds in cats

To evaluate a prototype pressure stimulus device for use in the cat and to compare with a known thermal threshold device.Eight healthy adult cats weighing between 3.0 and 4.9 kg.Pressure stimulation was given via a plastic bracelet taped around the forearm. Three 2.4 mm diameter ball bearings, in a 10-mm triangle, were advanced against the craniolateral surface of the antebrachium by manual inflation of a modified blood pressure bladder. Pressure in the cuff was recorded at the end point (leg shake and head turn). Thermal threshold was also tested. Stimuli were stopped if they reached 55 degrees C or 450 mmHg without response. After four pressure and thermal threshold baselines, each cat received SC buprenorphine 0.01 mg kg(-1), carprofen 4 mg kg(-1) or saline 0.3 mL in a three period cross-over study with a 1-week interval. The investigator was blinded to the treatment. Measurements were made at 0.25. 0.5, 0.75, 1, 2, 3, 4, 6, 8, and 24 hours after injection. Data were analyzed by using ANOVA.There were no significant changes in thermal or pressure threshold after administration of saline or carprofen, but thermal threshold increased from 60 minutes until 8 hours after administration of buprenorphine (p < 0.05). The maximum increase in threshold from baseline (Delta T-max) was 3.5 +/- 3.1 degrees C at 2 hours. Pressure threshold increased 2 hours after administration of buprenorphine (p < 0.05) when the increase in threshold above baseline (Delta P-max) was 162 +/- 189 mmHg.This pressure device resulted in thresholds that were affected by analgesic treatment in a similar manner but to a lesser degree than the thermal method. Pressure stimulation may be a useful additional method for analgesic studies in cats.

Effects of meperidine or saline on thermal, mechanical and electrical nociceptive thresholds in cats

Objective To measure cutaneous electrical nociceptive thresholds in relation to known thermal and mechanical stimulation for nociceptive threshold detection in cats.Study design Prospective, blinded, randomized cross-over study with 1-week washout interval.Animals Eight adult cats [bodyweight 5.1 +/- 1.8 kg (mean + SD)].Methods Mechanical nociceptive thresholds were tested using a step-wise manual inflation of a modified blood pressure bladder attached to the cat's thoracic limb. Thermal nociceptive thresholds were measured by increasing the temperature of a probe placed on the thorax. The electrical nociceptive threshold was tested using an escalating current from a constant current generator passed between electrodes placed on the thoracic region. A positive response (threshold) was recorded when cats displayed any or all of the following behaviors: leg shake, head turn, avoidance, or vocalization. Four baseline readings were performed before intramuscular injection of meperidine (5 mg kg(-1)) or an equal volume of saline. Threshold recordings with each modality were made at 15, 30, 45, 60, 90, and 120 minutes post-injection. Data were analyzed using ANOVA and paired t-tests (significance at p < 0.05).Results There were no significant changes in thermal, mechanical, or electrical thresholds after saline. Thermal thresholds increased at 15-60 minutes (p < 0.01) and mechanical threshold increased at 30 and 45 minutes after meperidine (p < 0.05). Maximum thermal threshold was +4.1 +/- 0.3 degrees C above baseline at 15 minutes while maximum mechanical threshold was 296 +/- 265 mmHg above baseline at 30 minutes after meperidine. Electrical thresholds following meperidine were not significantly different than baseline (p > 0.05). Thermal and electrical thresholds after meperidine were significantly higher than saline at 30 and 45 minutes (p < 0.05), and at 120 minutes (p < 0.05), respectively. Mechanical thresholds were significantly higher than saline treatment at 30 minutes (p <= 0.05).Conclusion and clinical relevance Electrical stimulation did not detect meperidine analgesia whereas both thermal and mechanical thresholds changed after meperidine administration in cats.

Right atrial stretch alters fore- and hind-brain expression of c-fos and inhibits the rapid onset of salt appetite

The inflation of an intravascular balloon positioned at the superior vena cava and right atrial junction (SVC-RAJ) reduces sodium or water intake induced by various experimental procedures (e.g. sodium depletion; hypovolaemia). In the present study we investigated if the stretch induced by a balloon at this site inhibits a rapid onset salt appetite, and if this procedure modifies the pattern of immunohistochemical labelling for Fos protein (Fos-ir) in the brain. Male Sprague-Dawley rats with SVC-RAJ balloons received a combined treatment of furosemide (Furo; 10 mg (kg bw)(-1)) plus a low dose of the angiotensin-converting enzyme inhibitor captopril (Cap; 5 mg (kg bw)(-1)). Balloon inflation greatly decreased the intake of 0.3 M NaCl for as long as the balloon was inflated. Balloon inflation over a 3 h period following Furo-Cap treatment decreased Fos-ir in the organum vasculosum of the lamina terminalis and the subfornical organ and increased Fos-ir in the lateral parabrachial nucleus and caudal ventrolateral medulla. The effect of balloon inflation was specific for sodium intake because it did not affect the drinking of diluted sweetened condensed milk. Balloon inflation and deflation also did not acutely change mean arterial pressure. These results suggest that activity in forebrain circumventricular organs and in hindbrain putative body fluid/cardiovascular regulatory regions is affected by loading low pressure mechanoreceptors at the SVC-RAJ, a manipulation that also attenuates salt appetite.

Pulmonary receptors in reptiles: discharge patterns of receptor populations in snakes versus turtles

This study examines the effects of lung inflation/deflation with and without CO2 on the entire population of pulmonary receptors in the vagus nerve in two species of snakes and two species of turtles. We asked the question, how does the response of the entire mixed population of pulmonary stretch receptors (PSR) and intrapulmonary chemoreceptors (IPC) in species possessing both differ from that in species with only PSR? This was studied under conditions of artificial ventilation with the secondary goal of extending observations on the presence/absence of IPC to a further three species. Our results indirectly illustrate the presence of IPC in the Burmese python and South American rattlesnake but not the side necked turtle, adding support to the hypothesis that IPC first arose in diapsid reptiles. In both species of snake, CO2-sensitive discharge (presumably from IPC) predominated almost to the exclusion of CO2-insensitive discharge (presumably arising from PSR) while the opposite was true for both species of turtle. The data suggest that for animals breathing air under conditions of normal metabolism there is little to distinguish between the discharge profiles of the total population of receptors arising from the lungs in the different groups. Interestingly, however, under conditions of elevated environmental CO2 most volume-related feedback from the lungs is abolished in the two species of snakes, while under conditions of elevated metabolic CO2, it is estimated that volume feedback from the lungs would be enhanced in these same species.

Bounds on direct couplings of superheavy metastable particles to the inflaton field from ultra high energy cosmic ray events

Top-down models for the origin of ultra high energy cosmic rays (UHECR's) propose that these events are the decay products of relic superheavy metastable particles, usually called X particles. These particles can be produced in the reheating period following the inflationary epoch of the early Universe. We obtain constraints on some parameters such as the lifetime and direct couplings of the X-particle to the inflaton field from the requirement that they are responsible for the observed UHECR flux.

Formation of wakes by chiral conducting cosmic strings

Chiral cosmic strings are naturally produced at the end of D-term inflation and they present very interesting cosmological consequences. In this work, we investigate the formation and evolution of wakes by a chiral string. We show that, for cold dark matter, the mechanism of forming wakes by a chiral string is similar to the mechanism by an ordinary string.

Desempenho operacional de trator com e sem o acionamento da tração dianteira auxiliar

Entre os fatores que podem influenciar o desempenho de tração do trator agrícola, destacam-se a pressão de inflação e a carga sobre o rodado motriz. Neste trabalho, o objetivo foi avaliar, em situação de campo, a influência dos fatores inflação (sob quatro níveis) e carga sobre o rodado motriz (sob quatro níveis), combinados com e sem o uso da tração dianteira auxiliar. O experimento, totalizando 32 tratamentos com três repetições, foi distribuído em blocos ao acaso. O trator estudado foi submetido a uma força de tração constante na barra de tração, imposta por outro trator. Os resultados evidenciaram a influência significativa da lastragem nos parâmetros patinagem e coeficiente de tração, que aumentaram com a redução da carga sobre o rodado. A pressão de inflação influiu significativamente nos parâmetros patinagem, velocidade de deslocamento e potência na barra, sem no entanto apresentar tendência de comportamento. O uso da tração dianteira auxiliar mostrou vantagens significativas em relação aos mesmos parâmetros anteriores. A interação dos fatores pressão de inflação e carga sobre o rodado mostrou que determinadas combinações de pressão foram mais favoráveis para o desenvolvimento de maior velocidade e menor patinagem. As características relacionadas ao desempenho do motor (consumo horário e rotação do motor) não foram afetadas por nenhum dos fatores e/ou suas interações.

Determinação da circunferência de rolamento de pneus agrícolas utilizando dois métodos: manual e eletrônico

A circunferência de rolamento dinâmica dos pneus agrícolas é uma medida importante para o estudo do desempenho de tratores agrícolas. Neste trabalho, compararam-se dois métodos de determinação da circunferência de rolamento dinâmica - um manual e um eletrônico (com instrumentação das rodas de tração) - sob duas velocidades de deslocamento e cinco combinações de pressão de inflação nos pneus dianteiros e traseiros. O método manual forneceu valores estatisticamente superiores aos do eletrônico, com diferença absoluta máxima de 0,24%. A pressão de inflação influenciou significativamente os valores medidos, enquanto a velocidade de deslocamento, para os valores do ensaio (3,0 e 6,0 km.h-1), não apresentou influência significativa.

Condições e relações de trabalho no serviço público: o caso do governo Lula

Cet article a l'objectif de détailler les diverses initiatives du gouvernement Lula (2003-2010) par rapport à la mise en forme d'une politique de ressources humaines et, de cette façon, vérifier s'il y a eu une amélioration des conditions et relations de travail dans le secteur public brésilien. À partir des années 1990, et dans le sens contraire de la grande croissance de l'emploi public dans les six décennies précédentes, l'adhésion des gouvernements brésiliens aux principes du « Consensus de Washington » souligne le fonctionnalisme comme point fondamental dans l'agenda des réformes nécessaires à la reprise de la croissance économique. Ces gouvernements là se sont penchés sur le traitement de l'emploi public comme étant un problème fiscal et ont agi pour restreindre sa dimension. Simultanément, les conditions et relations de travail se sont présentées plus fragilisées (rendues évidentes par l'absence de réajustement de salaire; la croissance de formes variables de rémunération ; l'élargissement du cadre de travailleurs temporaires et externes, e avec l'attitude autoritaire devant la représentation syndicale). Avec une recherche documentaire et bibliographique, on pourra remarquer que la restructuration de nombreuses carrières, la reprise des concours, la création de la « Réunion Nationale de Négotiation Permanente », la réforme de la sécurité sociale et les réajustements selectifs des rémunérations manifestent l'ambiguïté comme une marque fondamentale des politiques de ressources humaines. Cela parce que, au même temps, les progrès des conditions de travail du serviteur public ont toujours été accompagnés par l'entretien d'une partie de l'agenda conservatrice des années 1990, surtout par rapport à la reproduction de limites fiscaux rigoureux.

Estimativas de efeitos genotípicos sobre os desempenhos pré e pós-desmama de populações Hereford x Nelore

Objetivou-se obter estimativas de efeitos genéticos aditivos e não-aditivos para as características pré e pós-desmama de animais Hereford x Nelore por meio de análises de regressão linear múltipla, com e sem o uso da técnica de regressão de cumeeira. Avaliaram-se as características ganho médio diário do nascimento à desmama, conformação, precocidade e musculatura à desmama, ganho médio diário da desmama ao sobreano, conformação, precocidade e musculatura ao sobreano e perímetro escrotal ajustado para idade e para idade e peso. Os resultados obtidos sem o uso da técnica indicaram valores acentuados dos fatores de inflação da variância. Para melhor interpretar os efeitos estimados, foram preditos os desempenhos de cinco gerações na formação do Braford ½ em relação à raça Hereford, partindo de vacas da raça Nelore. Os animais da geração F1 apresentaram alto desempenho, em razão do benefício máximo da heterose direta e do efeito aditivo materno. A manifestação completa da epistasia direta reduziu significativamente os desempenhos dos animais da geração F2. Para as características de desmama, os animais da geração F3 mostraram desempenhos menores, em virtude do efeito epistático materno máximo, uma vez que suas mães eram da geração F2. Os valores destas características estabilizaram na geração F4, próximos aos valores apresentados pela raça Nelore. Os desempenhos das gerações F3 e F4 para as características pós-desmama e os valores das estabilizações foram próximos ou superiores aos obtidos na geração F2.
