Fractografia quantitativa e o conceito de tenacidade à fratura para a análise do efeitodo choque térmicos em TiO2

The present study evaluated the use of semicircular bending test (SCB) as an alternative to conventional bending test to examine the effect of thermal shock. Still, studies the behavior of fracture surfaces generated by monofractal behavior analysis, which allows us to evaluate the contributions of the microstructure and the mechanical context in forming reliefs during the crack propagation. The fractal analysis is made from elevation maps obtained by reconstruction method by extension of the focus stacks of digital images acquired in microscope. The specimens used were samples semicircular pressed TiO2 (rutile) with and without heat shock, prepared for testing mode I loading. Were also produced, specimens in the form of bars for Weibull statistical analysis. From the three-point bending test, we found the variation of fracture toughness between the samples after the heat shock and natural condition. The SCB test was feasible for the analysis of thermal shock resistance. The results showed that the value of the fracture toughness decreases as the heat shock treatment

O uso do treino de habilidades sociais em pessoas com fobia social na terapia comportamental

The effects of an intervention in social skills were assessed in four university students with ages between 19 and 31, with social phobia diagnosis. The performance in social skills as well as performance-compatible disorder was assessed before, after the intervention, and follow-up in four months later, by the instruments: SCID-I, Mini-SPIN, QACC-VU and IHS in a multiple baseline design among participants. The intervention programmed twelve weekly meetings in which the researcher discussed socially skilled alternatives to the described difficulties; leaded dialogued theoretical explanations about the theme of the meeting and also performed functional assessments and repertory training of the participants. It was observed deficits such as public speaking, starting and maintaining conversation in the participants’ social skills repertory, which are consistent with the criteria for social phobia and the difficulties into the adapting to university. After the intervention, the participants left difficulties in public speaking, performance characteristic compatible with the social phobia diagnosis and they also increased social repertory, although it is still necessary the improvement of other skills, such as expressing positive feeling.

Influence of time evolution in the modulus of elasticity of concrete reinforced by carbon fibers

The modulus of elasticity is an important property for the behavior analysis of concrete structures. This research evaluated the strain difference between concrete specimens with and without the application of laminate carbon fiber composites as well as the variation time, in months, of the axial strength compression and modulus of elasticity. Through the experimental results, it is concluded that increases in compressive strength and modulus of elasticity are more significant in the specimens without reinforcement.

Abordagem biocomportamental: síntese da análise do comportamento?

O artigo comenta as linhas gerais da abordagem biocomportamental a partir de dois trabalhos (Donahoe, Burgos, & Palmer, 1993; Donahoe & Palmer, 1994). A hipótese apresentada é a de que uma teoria sintética das origens do comportamento complexo mostraria como os efeitos cumulativos de processos de reforçamento relativamente simples levam à diversidade e complexidade do comportamento humano. Esses autores partem da simulação computacional para gerar analogias do fenômeno comportamental complexo, integrando processos neurológicos que tenham sido estabelecidos através de análise experimental. A integração de achados comportamentais e neurocientíficos constituiria uma síntese que poderia reivindicar a complexidade comportamental como seu domínio.

Valores do terapeuta na clínica analítico-comportamental

Desde os anos 1950, tem se constatado que, em alguma medida, os valores do terapeuta se fazem presentes na psicoterapia, podendo, inclusive, influenciar os valores dos clientes. Embora apresente uma concepção de valores diferente das tradicionais, a terapia analítico-comportamental não é uma exceção. Este trabalho busca esclarecer como os valores do terapeuta podem se manifestar na clínica analítico-comportamental, sejam esses valores pessoais ou compartilhados com alguma cultura (e.g., sociedade em geral, Psicologia, Análise do Comportamento). Para tanto, mostra-se como o conceito de valor tem sido abordado na Análise do Comportamento e o que possibilita a manifestação dos valores do terapeuta na clínica analítico-comportamental. Por fim, discutem-se brevemente algumas implicações do tema para a prática clínica.

Ensino de leitura de sentenças: contribuições da análise do comportamento

O paradigma da equivalência de estímulos tem sido pouco usado para estudar o ensino de leitura de sentenças. Assim, o presente estudo avaliou o efeito de um procedimento de ensino e testes de relações condicionais seguidos pelo encadeamento de palavras sobre a leitura com compreensão de sentenças e a generalização de leitura. Participaram oito escolares, com 7 e 9 anos de idade. O procedimento incluiu pré e pós-teste, três fases de ensino e testes de leitura com compreensão, um teste de conectividade e um teste de construção de sentenças. A leitura de palavras e de sentenças melhorou do pré para o pós-teste em todos os casos, demonstrando que o procedimento foi efetivo para ensinar leitura com compreensão de sentenças.

Conseqüências do externalismo behaviorista radical

O artigo discute a proposta de Skinner para a ciência do comportamento, caracterizando-a como "externalista" (voltada para as relações do organismo com eventos que lhe são externos). Examina-se o discurso de Skinner sobre diferentes explicações para o comportamento, em obras de 1938, 1953 e 1990, a fim de indicar sua preocupação permanente com a definição das fronteiras entre análise do comportamento e (neuro)fisiologia. Apontam-se aspectos da elaboração skinneriana que a tornam insuficiente para sustentar uma declaração coerente sobre a autonomia de uma ciência do comportamento e procura-se ilustrar como essa dificuldade se reflete na literatura contemporânea da área.

Metacontingencies, Experimentation and Nonhumans: Searching for Conceptual and Methodological Advances

Metacontingency has been described as the functional relation between interlocking behavioral contingencies, plus their direct and immediate effect, called aggregated product, and a selecting event dependent of such effect, called cultural consequence. The metacontingencies analysis enables the discussion of human behavior complexity in social systems. In the present study, we aimed to review and discuss: (a) the importance of basic behavioral processes analysis for the comprehension of social human phenomena; (b) the necessity of constructing and improving metacontingencies experimental models; (c) the current state of metacontingencies experimental investigations in humans; (d) the use of animal models as a way to control the effects of verbal behavior, among other variables, over cultural selection; (e) a concrete and illustrative proposal of an animal model of metacontingencies.

The physical city and the urban structure: detecting amenity zones and applying urban morphology to New York

The city is a collection of built structures and infrastructure embedded in socio-cultural processes: any investigation into a city’s transformations involves considerations on the degree to which its composite elements respond to socio-economical changes. The main purpose of this research is to investigate how transformations in the functional requirements of New York’s society have spurred, since the 1970s, changes in both the city’s urban structure and physical form. The present work examines the rise of Amenity Zones in New York, and investigates the transformations that have occurred in New York’s built environment since the 1970s. By applying qualitative measures and analyzing the relationship between urban amenities and the creative class, the present work has investigated changes in the urban structure and detected a hierarchical series of amenity zones classes, namely, Super Amenity Zones (SAZs), Nodal Amenity Zones (NAZs) and Peripheral Amenity Zones (PAZs). This series allows for a more comprehensive reading of the urban structure in a complex city like New York, bringing advancements to the amenity zone’s methodology. In order to examine the manner in which the other component of the city, the physical form, has changed or adapted to the new socio-economic condition, the present research has applied Conzenian analysis to a select study area, Atlantic Avenue. The results of this analysis reveal that, contrary to the urban structure, which changes rapidly, the physical form of New York is hard to modify completely, due to the resilience of the town plan and its elements, and to preservation laws; the city rather adapts to socio-economical changes through process of adaptive reuses or conversion. Concluding, this research has examined the dialectic between the ever-changing needs of society and the complexity of the built environment and urban structure, showing the different degrees to which the urban landscape modifies, reacts and sometimes adapts to the population’s functional requirements.
