A pesquisa em psicologia: ensaio sobre a Psicologia enquanto ciência, a pesquisa qualitativa e o uso da entrevista como principal instrumento de coleta de dados

For constituting itself a science, Psychology has coursed along way. From the time he was considered a Philosophy’s discipline until to be recognized as a legitimate science, Psychology had to devoteto the definition of its object of study, the development and refinement of theoretical-methodological frameworks and, in particular, to consolidation process of their research strategies and knowledge construction. Therefore, in order to regard the demands of the classical scientific paradigm, which is very influenced by Positivism, Psychology made use, initially, of quantitative methodology and laboratory research. This article presents some of the process of identity construction of Psychology as a science, focusing on its transition path between the quantitativist paradigm of scientific knowledge production to the qualitativist paradigm, until that is more commonly practiced nowadays: the collaborative use of these methodological strategies. For presenting the qualitative researching Psychology, we discussed, beyond its proposal and differentiation elements in relation to quantitative research, the different methods used for this mode and, in particular, the interview - which is considered the main way of data collection in surveys conducted by psychologists and, therefore, it is an important element the process of knowledge building that science, in addition to being the most qualified space for dialogue between there searcher and the research subject.

Dispositivo estratégico, resistência e relações de poder: um ensaio sobre a identidade do Centro de Educação Matemática (CEM) e seu papel na (E)educação (M)matemática brasileira

This paper presents some results of the investigation on the Mathematical Education Centre (CEM), a group of mathematics teachers’ educators in São Paulo, Brazil, acting mainly between 1984 and 1997. The essay, marked by an effort to constitute the identity of the CEM based on Foucault, assumes that the identity constitution process is not about what CEM is or was, but mainly about a set of possibilities of apprehending it from its historically contextualized strategies and initiatives. In this Foucauldian reading, which brings about concepts such as "strategic device", "resistance" and "power relations", the CEM constitution appears while it creates conditions for the constitution of Brazilian modern mathematical education.

As matemáticas modernas: um ensaio sobre os modos de produção de significado ao(s) movimento(s) no ensino primário brasileiro

The main goal of this paper is to discuss the production of meaning of the Modern Math Movement. The main sources were data available in school archives and interviews with former teachers that we use in order to focus on the diversity of perspectives -that complement it or oppose it-, which comes up when teachers refer to the Movement. Using this process of signification, teachers whether accept it, invalidate it or adapt it to guidelines imposed to them in their teaching activities. We establish a methodology by following the premises of Oral History to gather oral testimonies. The theoretical foundations in which this article is written are the guidelines of Paul Ricoeur’s Hermeneutics, John Thompson’s Depth Hermeneutics and Bolívar’s narrative analysis.

Deposição e danos mecânicos em sementes de sorgo utilizando um mecanismo dosador de fluxo contínuo em ensaio de bancada

This study aimed to evaluate the behavior of the deposition and mechanical damage in seeds using a continuous flow metering system under different slope and speed. Part of the study was conducted at Agricultural Research Foundation Agricultural - (FAPA), where seeds that are deposited by a metering system were collected, and the quality analysis verifying the percentage of mechanical damage were conducted at the Faculty of Agricultural Sciences, UNESP, city of Botucatu– SP. The mechanism deposition was subjected to three different speed conditions (4,7, and 10 km.h-1) and three differents working slopes, ( 3%, 8%, and 16%). The results were submitted to Tukey test (p ≤ 0.05), and an analysis of variance with F test at 5% significance level was performed. The results showed an interaction between the factor slope and speed of work, increasing the metering mechanism speed, results in a reduction of the seed deposition at a 3% slope but a working speed of 10 km h-1did not reduce the rate of seed deposition until the slope reaches 16%. Both the slope factor and the working speed caused at least 3.9 and 4.2% more damage to the seeds, respectively.

Avaliação do tempo de resposta de um controlador de fluxo com DGPS submetido à variação de velocidade de voo em condições de voo simulado em laboratório

The application of pesticides is one of the most important steps in the agricultural production process. The spray volume can directly affect application success, and this parameter is directly dependent on the displacement speed of the sprayer. In conventional systems, the operator has to maintain a constant speed to ensure uniform application along the tracks. In order to improve over application quality and preserve levels of precision for applied doses; the use of electronic flow control systems allows for automatic adjustment of volume applied over the area when there is a change in velocity during application. The objective of this research was to study the response times of a flow controller with DGPS for aerial application subjected to variations of velocity in laboratory simulated flight conditions. For this purpose, a bench test has been developed including software for simulating DGPS signals, which was used to simulate different flight speeds and conditions. The results showed the average response time from the flow controller to a change in velocity to be between 6 and 20 seconds. Variations in total flow and the controller setting had a significant influence on response time with situations where there was interaction between the factors being evaluated. There was a tendency for better response times using a constant setting for the control algorithm other than that specified by the manufacturer. The flow controller presented an average error rates below 2% in all evaluated operating conditions, providing satisfactory accuracy in determining the output of product in different test situations.
