O papel da nominalização no continuum categorial

A continuidade categorial é uma propriedade indiscutível da linguagem para a tradição funcionalista, que a trata como um verdadeiro universal linguístico. Além de buscar evidência sistemática para a comprovação desse axioma, o principal objetivo deste trabalho é analisar a estrutura argumental da nominalização, num esforço concentrado por demonstrar que esse mesmo princípio universal é metodologicamente útil e teoricamente válido para postular relações intralinguísticas de continuidade categorial mesmo entre classes aparentemente discretas como as de substantivo e verbo. A trajetória percorrida para a sustentação da hipótese da continuidade categorial passa necessariamente pela comprovação de uma hipótese secundária, a de preservação de valência, postulada por Dik (1985; 1997), segundo a qual a estrutura argumental é parte constitutiva da nominalização. Essa busca não teria êxito se a trajetória percorrida não utilizasse um atalho necessário, representado pela teoria prototípica de categorização. De fato, postular a existência de categorias intermediárias, como a de nominalização, implica necessariamente a existência de membros mais prototípicos de uma categoria. A existência de estrutura argumental, que sinaliza a representação de entidades de ordem superior, permite aproximar a nominalização de membros não-prototípicos da categoria dos verbos como formas não-finitas, enquanto a ausência de estrutura argumental, que sinaliza a representação de uma entidade de primeira ordem, permitiu aproximá-lo de membros prototípicos da categoria dos substantivos

O egocentrismo infantil na perspectiva de Piaget e representações de professoras

This text comes up a clipping from an applied research, qualitative approach, which sought to understand both the egocentric second Piaget, through a literature search, furthermore, from a study that was conducted with teachers from kindergarten and the first years of elementary school, we sought to delineate the representations of such teachers in this regard and its proximity to the theory in question. Therefore, the trajectory traveled consisted of explaining aspects the Vygotsky's critique to Piaget, with respect to egocentric thought; subsequently show how as Piaget responded to criticism of Vygotsky, and expound upon the egocentric thought present in your perspective. Were addressed, we sought to delineate the representations of fifteen educators about the phenomenon of egocentrism in children and its proximity with the theory of Piaget. It might thus as regards the literature, and bring the importance of recognizing and understanding the thought egocentric in Piaget, as a phenomenon is intrinsically linked to the development of the child and that we can approach your understanding. For representations of teachers, approached more subjectively common sense than the concepts found in psychological theory focused. Thus, this study allows us to understand the limits and scope of training courses for teachers, with regard to the dimension in focus.

Eletroestimulação em pacientes portadores de doença pulmonar obstrutiva crônica

Patients with Chronic Obstructive Pulmonary Disease may have muscle dysfunction, which ultimately reduce the functional capacity. Neuromuscular electrical stimulation (NMES) is a technique that can be effective in these patients, and implies low overload to the cardiorespiratory system. The aim of this study was to investigate the effects of NMES on muscle strength and cardiorespiratory fitness in COPD patients. Five patients (2 men, 3 women) were evaluated, with a mean age of 70.40 ± 6.61 years, and underwent anamnesis, anthropometric measurements, spirometry, pulmonary function, cardiopulmonary functional capacity and muscle strength in the lower limbs. After the evaluations, the patients were enrolled in a program of electrical stimulation of the quadriceps muscles, performed 3 times per week for 5 weeks. Each session lasted for 30 minutes, being reassessed at the end of the 15 sessions. Statistically significant response is observed to gain strength in lower limb (p = 0.005), but no significant responses were observed for the distance in six minute walking test before and after the test protocol for electrical stimulation. Showing that with NMES was located just gain muscle strength without effects on functional capacity, and there are few studies that investigate these effects, so further studies are needed to investigate this relationship.

Comparação das variáveis hemodinâmicas durante o teste de caminhada de seis minutos e o teste de escada em adultos saudáveis

The effort test can be used to assess functional capacity, clinical hemodynamic and metabolic response at the effort, the risk of postoperative pulmonary complications and to assess the response of patients with lung diseases submitted to physiotherapy treatment. Among the stress tests we highlight the Six Minute Test Walk (6 MWT) and Stair Climbing Test (SCT), because they are easy to use and low cost. Especially the SCT is widely used in patients preoperatively. Objective: To compare the effects of six minute walk test and stair climbing test under the hemodynamic and oxygenation in healthy adults. Methods: We conducted a study with healthy subjects above 50 years. The fi rst performed was 6 MWT in quick step with encouragement, in a plan corridor of 30 meters, where the shade was determined the distance walked in 6 minutes, after 6 MWT was performed de SCT with encouragement, on a ladder in shade, consists of 44 steps, with 4 bids and bid by 11 steps, each step measured 16 cm in a total of 7.04 m of height, where the rise time was clocked. Before and after the two tests were measured respiratory rate, pulse, blood pressure and oxygen saturation. Results: We evaluated 21 patients with age 59.6 ± 5.4 years, 5 men and 16 women. The average distance covered on the 6MWT was 496.4 ± 102.2 meters and the average time in SCT 22.6 ± 5.4 seconds. The variables pulse, respiratory rate, systolic blood pressure and Borg scale presented a signifi - cant increase after the tests, however the variables oxygen saturation and diastolic blood pressure did not change signifi cantly. Conclusion: The variables pulse, respiratory rate, systolic blood pressure and Borg scale tests increased after six-minute walk test and stair climbing test but with greater signifi cance after the stair climbing test. Oxygen saturation and diastolic blood pressure did not change signifi cantly after the tests.

Existe correlação entre força muscular com o teste de caminhada de seis minutos em idosos institucionalizados?

The six-minute walking test can be affected by several variables, among them, the respiratory and peripheral muscle strength. The objective of this study was to correlate the respiratory muscle strength (maximum inspiratory pressure – MIP; and maximum expiratory pressure – MEP) and the hand grip test (HGT)with the six minute walking test distance in institutionalized elderly. It was included in this study 9 institutionalized elderly with age over 70 years old, both gender, evaluated by means of manometer, dynamometry and six minute walking test. The data were correlated by using the Pearson’s correlation test and the Spearman correlation test. From the evaluated elderly, it was four men and five women, with mean age: 78.8±7.3 years old, MIP: 75.7±33.6 cmH2O, MEP: 62.4±25.0 cmH2O, HGT: 20.4±6.2 kgf (right member) and 20.7±6.8 kgf (left member) and the distance on six minute walking test: 238.5±99.0 meters. There was correlation between expiratory strength and hand grip of both members with the distance on the six minute walking test. It is possible to conclude that there are correlation between expiratory muscle strength with the hand grip test and the functional capacity in institucionalized elderly.

Efeito da matriz na capacidade de aves flrestais moverem-se na paisagem

Matrix can be defined as a portion of the landscape, that somewhere in time suffered intense human disturbance, such as decreasing of native vegetation. The matrix surrounding the forest fragments may create a certain resistance to the movements of individuals (RICKETTS, 2001). The Atlantic rainforest present in the Corumbataí river basin lost about 89% of its original vegetation, leading to a highly fragmented landscape (VALENTE e VETTORAZZI, 2005). In this context, this study aimed to evaluate the effect of the matrix and the characteristic capacity of two forest birds, Dysithamnus mentalis and Basileuterus flaveolus, moving around the landscape. With this aim, six fragments were selected, three with sugar cane matrix, three with Eucalyptus sp. matrix. The methodology utilized to evaluate the response of the birds was playback technique. First the vocalizations were carried out at the forest matrix boundary, in the edge, attracting individuals to the matrix. As the responses were generated, the playback was moved increasingly inside the matrix, observing the distances traveled by the species. The control trials were conducted inside the fragments, the playback was played at the edge and as the responses were observed, the vocalizations were carried out inside the fragment until the moment that individuals ceased answers. It could be observed that for individuals of D. mentalis the matrix generated a high resistance, because no individual entered the matrix. For B. flaveolus the average distance traveled in both matrices was 70 meters, indicating statistically high resistance of the sugar cane matrix and Eucalyptus sp. Considering the characteristics of different matrices, it was found that both matrices generate similar resistance in the movement of these species

Correlações fisiológicas da carga parasitária em Rhinella icteriucus (Anura: marinus)

A presença de parasitas, que podem afetar inúmeros aspectos da biologia de seus hospedeiros, possivelmente levando a uma queda em seu desempenho. Entretanto, ao longo do estabelecimento da associação parasita-hospedeiro, alterações na fisiologia e morfologia deste último podem representar mecanismos compensatórios para os danos causados pelos parasitas. Sendo assim, carga parasitária deve ser um importante determinante do valor adaptativo (fitness) do hospedeiro. O objetivo do presente trabalho foi estabelecer possíveis correlações entre carga parasitária, massas de diversos órgãos e desempenho locomotor no sapo-cururu, Rhinella ictericus (Anura: Bufonidae). O desempenho locomotor dos indivíduos capturados de R. ictericus foi medido através do uso de uma pista circular de madeira. Durante um período de 10 minutos, os animais foram forçados a manter desempenho locomotor constante e a distância total percorrida foi corrigida para o comprimento rostro-cloacal. Depois das medidas de desempenho locomotor, os órgãos internos foram dissecados, tendo seus parasitas contabilizados. As massas de todos os órgãos escalaram positivamente com a massa corpórea. O número de parasitas nos pulmões e o índice corpóreo também se mostraram positivamente relacionados à variação em massa corpórea. Indivíduos com maior carga parasitária intestinal foram também aqueles que apresentaram um maior número total de parasitas, sugerindo a existência de variação individual na susceptibilidade a diferentes parasitas. O desempenho locomotor foi negativamente associado à carga parasitária total, demonstrando um efeito deletério causado pelos parasitas ao hospedeiro em um aspecto crucial de sua história de vida. Hospedeiros com maior carga parasitária pulmonar apresentaram maior massa intestinal e renal, sugerindo possíveis mecanismos compensatórios dos possíveis danos causados pelos parasitas

Uso de algoritmos genéticos na otimização do sistema de coleta do palhiço de cana-de-açúcar

The Brazilian government has convinced the world that ethanol deriving from sugar cane is a promissory means of sustainable fuel for vehicles. There is a great growth of ex vehicles , i.e, run both by ethanol and gasoline, due to competent automotive industries and e cient alcohol production technology. In 2009 and 2010 the ethanol production was 25.7 billion liters and 53.8% of sugar cane production was destined to alcohol production. Nevertheless, the sugar production also derived from sugar cane should increase in 2011. Brazil produced 33 million tons of sugar in the last harvest. With sugar cane on the rise production is arising new environmental problems. The harvest using mechanized cut besides improving the logistic transportation system leaves the generating residue in the eld. This residue is a mixture of straw, leavings and scrap of sugar cane named sugar cane crop residue and corresponds to 30% of biomass and can be burned and produce electricity by cogeneration. But the transport the sugar cane crop from the eld is expensive due costs involved in the transport system. This work aims to propose a formulation for the bales collecting problem from sugar cane eld to mill that minimize the costs involved in the transport system. The computational tests use the C++ language and an algorithm based on genetic algorithms techniques

Dimensionamento de estoques de materiais elétricos em centros de distribuição

Due to the high level of service required by customers and the constant need to reduce costs, the logistics can be considered as a strategic area for a company. In particular, the order picking is responsible for most of the operating costs in a warehouse. Therefore it’s necessary to plan the materials storage in order to maximize the space available and minimize the total distance traveled to meet customer orders. For these reasons, this study aims to examine and propose a way to organize the electrical materials storage in distribution centers through a study on an electronics company in Cajamar
