On lag controllers: Design and implementation

Sometimes it is inconvenient or expensive to open the loop of a system to insert lag controllers-for instance, when this system is an open-loop system. A new controller structure where the loop is not opened, and that allows the design of lag controllers as in the case where one can open the loop, is presented. This result can be used by educators in undergraduate courses that deal with classic control system theory, because it allows a better comprehension of the concept of lag compensation and provides a new method for its design and implementation. An example illustrates the application of the proposed method.

A Psicologia do trabalho e das organizações na formação do psicólogo no Brasil

This research has aimed to analyze the presence of the Work and Organizational Psychology (WOP) at the psychologist s undergraduate education after 2004 s National Curricular Guidelines in Brazil. It has investigated in 43 Brazilian undergraduate courses of Psychology how their Course Pedagogical Projects (CPPs) approach the WOP issues. For that investigation, the CPPs, the subjects programmes related to the WOP and the curriculum grid have been accurately read and analyzed. Categories created by similar studies have also been used. The studied knowledge field has been cited by 41 courses, mainly on the definition of the egress s professional profile, on the expected competences and on the psychologist s formation process lines. Moreover, 28 courses have disposed curricular emphasis on the WOP and 12 have provided professional practices on that Psychology s field. All the courses have displayed, at least, one subject related to the WOP and in 29 cases there have been found between two and six subjects concerned to that field of Psychology, occupying nearby 10% of the whole courses credit hours. It has been verified that the Work and Organizational Psychology is allied to discussions about Quality of Life and Health of the Worker, bonded to work prescriptions at the Personnel Management departments and in other places such as syndicates. Additionally, 37% (147) of the WOP s subjects concerns to the contents of the Work Psychology, 21% (81) relates to the Organizational Psychology, 18% (71) are about Industrial Psychology s topics and 14% (55) debates the field generically. The most often issues are: Recruitment and Selection (25 courses); Training, Development, Learning and Education (24); and Work and Mental Health (24). Those topics have assumed three functions: providing principles for the acting at the WOP field; tutoring psychologists to analyze their own workplaces; and offering a comprehension of the human being mediated by the Work. It has been concluded that the WOP is incorporated on the psychologist s undergraduate education by considering the increasing of its presence and the occurrence of its traditional and emergent topics

Contribuições do Programa Institucional de Bolsas de Iniciação Científica (PIBIC) para a formação do aluno de psicologia

The undergraduate courses in Psychology have been historically pointed as defective in aspects related to the critical education and the integration between theory and practice. Hence, the scientific education has been considered a possibility to overcome those lacks. Therefore, this study has investigated the undergraduate education process of Psychology students with PIBIC (Portuguese acronym for Undergraduate Scientific Research Scholarships Institutional Program) scholarships from CNPq (Portuguese acronym Brazilian National Council of Scientific and Technological Development). The scholarship program has been a strategic tool for the undergraduate scientific research. Electronic questionnaires have been sent to all the PIBIC scholarship students of Psychology in Brazil (622; 104 have answered), containing questions about the program developed activities, tutoring and advising, PIBIC evaluation and other ones. The students scientific and academic production has also been investigated through their Lattes (CNPq s Platform in which researchers have their academic résumés). The major part of the participants (70%) has stated that the first motivation to be in the program had been their interest in the research or in the academic career. Furthermore, 60% of the scholarship students has worked as volunteers before receiving PIBIC scholarship. Among the students who have answered the research, 65,4% has reported they are tutored directly by their advisors, and 80% of them attends one or more than one advising meeting every fifteen days. It has been identified that the Psychology scholarship students do not participate in all the research activities and that the proximity with the advisor is related to the accomplishment of tasks which contributes with the student critical and reflexive education. Finally, less than 25% of the students has published scientific articles or book chapters during the scholarship, what XI demonstrates a possible exclusion of them in that phase of the process. In general, the scholarship students evaluate the program positively by revealing that it contributes with their professional and academic education. For those reasons, it is observed PIBIC s potential role for the undergraduate education in order to develop more critical psychologists able to propose innovations and contextualized practices. However, the results obtained in programs like the studied one denounce the disqualification of the provided undergraduate education for the major part of the university students, who do not have a PIBIC scholarship. As a result, it is emphasized that it there should be more investment for improving the quality of the undergraduate education itself and not only for programs which are available for few students

Projeto criança saudável, educação dez: resultados com e sem intervenção do nutricionista

OBJETIVO: Planejar e aplicar um programa de orientação em nutrição, realizado por nutricionista e destinado a professores de 1ª a 4ª série do ensino fundamental, visando analisar a contribuição desse profissional no resultado do projeto Criança Saudável, Educação Dez quanto ao conhecimento dos escolares. MÉTODOS: O trabalho foi realizado em duas escolas públicas, A e B, nas quais foi desenvolvido o projeto educativo, sendo que na primeira os professores foram apoiados por um programa de orientação realizado por profissional nutricionista. Antes e depois do desenvolvimento do projeto educativo foi aplicado um instrumento para avaliar o conhecimento dos escolares sobre alimentação e nutrição. RESULTADOS: Os escolares da Escola A apresentaram mudança significante (p<0,01) no conhecimento de alimentação e nutrição após o desenvolvimento do projeto educativo, o que não ocorreu entre os estudantes da Escola B (p>0,05). CONCLUSÃO: Os resultados obtidos sugerem que a realização de programa de orientação, prestada por nutricionistas aos professores para desenvolverem o projeto educativo, maximizou os resultados, gerando mudança significante no conhecimento dos escolares sobre alimentação e nutrição. Tais resultados apontam a importância da capacitação do nutricionista para atuar em educação nutricional, indicando que o campo pedagógico merece aprofundamento nos cursos de graduação, de modo a permitir ao aluno e futuro profissional uma compreensão alicerçada e sólida do processo educativo.

O atletismo nos cursos de graduação em Educação Física

This study has the purpose to investigate the characteristics and the role of the athletics-related sports disciplines in four Physical Education undergraduate courses. In order to reach the goal, it was conducted as a qualitative-type research. Data was collected through documental analysis on disciplines briefings and programs, and also from classes observations and interviews with professors and students from the institutions (two State-boarded and two private) responsible for the courses. Through these analyses it was perceived that those disciplines have surpassed some characteristics of the traditional undergraduate program, which is based on sports. Regarding the role of the disciplines, it was noted that professors consider them as responsible for providing students with basic conditions, so they could benefit from sports as instrumental subjects for their professional intervention.

Formação dos educadores ambientais e paradigmas em transição

Este artigo trata dos pressupostos teóricos presentes na formação dos educadores ambientais nos cursos de graduação das universidades e resulta da tese de doutorado da autora. Esses pressupostos definem um quadro teórico analisado a partir do referencial metodológico do materialismo históricodialético. Esse quadro teórico pode ser organizado, pelo núcleo das representações dos professores, em concepções naturais, racionais e históricas da relação homem-natureza e da educação. A análise dessas tendências revela um movimento de superação dos paradigmas tradicionais presentes na organização curricular na universidade.

Challenges of teaching corporate environmental management in Brazil

This paper sheds light on the main challenges of teaching Corporate Environmental Management (CEM) in Brazil. Thus, we analysed the main challenges for CEM in Brazil from the viewpoint of teachers. The objective of the research is achieved by means of interviews performed with five renowned professors responsible for teaching CEM in undergraduate courses. Results indicate five types of barriers for teaching CEM: weak integration of other teachers in the teaching of CEM; low level of acceptance of CEM as a subject by the peers teachers; a lack of focus on business while teaching CEM; a scarcity of CEM teaching materials appropriate for the realities of Brazil; and a relative lack of interest among some students in CEM. Teaching CEM is fundamental for the education of more responsible students, but little is known about teaching CEM in Brazil.. Copyright © 2013 Inderscience Enterprises Ltd.
