Cuidado com o Cuidador! uma análise da tarefa

The home care is a growing activity in homes around the world. Many benefits are related to the practice, but the health risks involving the caregiver is the issue of this analysis. Through field interviews and in loco evaluation is raised a previous scope of this peculiar and complex task.

A crítica da Psicologia e a tarefa da crítica na Psicologia

This article discusses the need to deepen Psychology criticism as a science, unveiling its ideological commitment to the demands posed by the capitalism development and, at the same time, develop the critical thinking in Psychology. Taking the dialectical historical materialism as a basis, the main elements which should be contemplated by the critical thinking are presented: the dialectical reflection; the knowledge criticism; the denounce of degradation, alienation and human heteronomy in the conditions posed by capitalism and the possibility of being used as an instrument in the social transformation process. The incorporation of these elements can guide the constitution process of psychological knowledge which will be able to provide more satisfactory answers to questions concerning the dialectical relationship between individuals and society and the possibilities of human emancipation in nowadays society.

Desempenho de movimentos cíclicos e discretos realizados em tarefa de Fitts simulada em computador

Performance of cyclical and discrete movements executed in Fitts’ task simulated by computer Abstract This study compared the performance of cyclical and discrete movements in Fitts’ task simulated by a computer. Twenty male adults, between 25 and 30 years old, participated as volunteers in the study. The software Discrete Aiming Task (v.2.0) simulated the Fitts’ task, in the discrete and cyclical conditions, and provided the movement time (TM). It was manipulated 4 target widths and 3 distances between the targets to provide index of difficulties (ID) from 1 to 6 bits. The ANOVA TWO WAY, 3 (Conditions) x 6 (ID), with repeated measures in the last factor, compared the TM in the different conditions. Regression analysis verified the relationship between TM x ID. There were no significant differences between the conditions; the virtual environment and the mouse were used to explain such results. All movement conditions showed a straight relationship between TM x ID with R²>0.990. Therefore, Fitts’ law showed to be consistent, independently of the movement strategy performed.

Medidas de condutividade A.C. e constante dielétrica na perovskita dupla Ca1.2 La0.8 FeIrO6

This work introduces the results from the performing of impedance spectroscopy on the transition metals oxide Ca1.2La0.8FeIrO6. It was sought to understand the behavior of one sample from its impedance spectra for different AC voltages and temperature values and if an applied external magnetic field at room temperature would cause some change on it. The results revealed that the Ca1.2La0.8FeIrO6 at high temperatures shows conductive and inductive behavior and that the resistance increases with frequency, phenomenon known as Kelvin effect. At 150 K, the spectrum real part no longer consists with the theoretical prediction of Kelvin effect, starting to be influenced by the utilized voltages, condition that inexists on theory. At low temperatures (10, 20, 30 K) it was observed resistive and capacitive behavior, being possible on these conditions, associate to the sample a paralel RC circuit in series with a contact resistance with a fitting from the ZSim software. This fitting allowed the obtaining of capacitance, DC resistance and contact resistance values. The application of a 700G magnetic field at room temperature didn't cause changes on the spectra
