Variable parameter and double sampling (X)over-bar charts in the presence of correlation: The Markov chain approach

The general assumption under which the (X) over bar chart is designed is that the process mean has a constant in-control value. However, there are situations in which the process mean wanders. When it wanders according to a first-order autoregressive (AR (1)) model, a complex approach involving Markov chains and integral equation methods is used to evaluate the properties of the (X) over bar chart. In this paper, we propose the use of a pure Markov chain approach to study the performance of the (X) over bar chart. The performance of the chat (X) over bar with variable parameters and the (X) over bar with double sampling are compared. (C) 2011 Elsevier B.V. All rights reserved.

Teaching the Rational Use of Medicines to medical students: a qualitative research

Background: Prescribing is a complex and challenging task that must be part of a logical deductive process based on accurate and objective information and not an automated action, without critical thinking or a response to commercial pressure. The objectives of this study were 1) develop and implement a discipline based on the WHO's Guide to Good Prescribing; 2) evaluate the course acceptance by students; 3) assess the impact that the Rational Use of Medicines (RUM) knowledge had on the students habits of prescribing medication in the University Hospital.Methods: In 2003, the RUM principal, based in the WHO's Guide to Good Prescribing, was included in the official curriculum of the Botucatu School of Medicine, Brazil, to be taught over a total of 24 hours to students in the 4th year. We analyzed the students' feedback forms about content and teaching methodology filled out immediately after the end of the discipline from 2003 to 2010. In 2010, the use of RUM by past students in their medical practice was assessed through a qualitative approach by a questionnaire with closed-ended rank scaling questions distributed at random and a single semistructured interview for content analysis.Results: The discipline teaches future prescribers to use a logical deductive process, based on accurate and objective information, to adopt strict criteria (efficacy, safety, convenience and cost) on selecting drugs and to write a complete prescription. At the end of it, most students considered the discipline very good due to the opportunity to reflect on different actions involved in the prescribing process and liked the teaching methodology. However, former students report that although they are aware of the RUM concepts they cannot regularly use this knowledge in their daily practice because they are not stimulated or even allowed to do so by neither older residents nor senior medical staff.Conclusions: This discipline is useful to teach RUM to medical students who become aware of the importance of this subject, but the assimilation of the RUM principles in the institution seems to be a long-term process which requires the involvement of a greater number of the academic members.

Acquisition of suture skills during medical graduation by instructor-directed training: A randomized controlled study comparing senior medical students and faculty surgeons

Due to shortage of time and limited availability of faculty surgeons to teach basic surgical skills during medical graduation, the search for alternative ways of simulated training with feedback is needed. The purpose of this study was to compare the simulated teaching of suture skills to novice medical students by senior medical students and by experienced faculty surgeons. Forty-eight novice medical students were randomly assigned to three practice conditions on bench model (n = 16): self-directed suture training (control), senior medical student-directed suture skills' training, or experienced faculty surgeon-directed suture skills' training. Pre- and post-tests were applied. Global Rating Scale with blinded evaluation and self-perceived confidence based on Likert scale were used to assess all suture performances in pre- and post-training. Effect size was also calculated. The analysis made after training showed that the students who received feedback from the instructors had better performance based on the Global Rating Scale (all p < 0.0000) and felt more confident to carry out sutures (all p < 0.0000) when compared to the control. There was no significant difference (all p > 0.05) between the student-directed teaching and faculty-directed teaching groups. The magnitude of the effect (instructor-directed training suture) was considered large (>0.80) in all measurements. The acquisition of suture skills after student-directed training was similar to the training supervised by faculty surgeon, and the increase in suture performances of trainees that received instructor administered training was superior to self-directed learning. © 2013 Springer-Verlag Italia.

Movimento jogo e brincadeira na educação infantil: as expectativas das famílias

Childhood is a theme that has attracted many controversies and discussions, and winning approaches to the increasingly large over time: biological, psychological, educational, welfare and, more recently, sociological. It is known that the movement, play and game activities are important recurrent and integral development of children, and should be present prominently in early childhood institutions. Based on these assumptions is that this study aimed to analyze the didactic-pedagogical principles postulated by the law, official guidelines didactic teaching and literature, with regard to meeting the needs of children in early childhood education. Unveiling the expectations of the families responsible for children in relation to early childhood education, especially with regard to movement, and play games and compare to what extent these expectations turn away or close to the guidelines on teaching and pedagogical movement, games and postulated in official documents, legislation and literature. To this end, we carried out literature search, selection and analysis of texts relevant to the understanding of the theme. Fieldwork was conducted in a Municipal School of Early Childhood Education Full-time (Emei) of Bauru/SP, and involved the analysis of the Political-Pedagogical Project of the institution, semi-structured interviews with five teachers and five children in the family responsible for Garden II (ages 5 to 6 years). Data were analyzed using thematic content analysis of Bardin and triangulated by the confrontation of literature/legislation, the Pedagogical Political Project of the institution and the expectations of families/guardians. We also realize that the Pedagogical Political Project of EMEI is in routine activities with the children, movement, and play the game are covered and are worked. According to teachers interviewed they assist in learning other areas of work (Oral and Written Language, Nature and Society, etc.) learning of moral...

Analytical solution for transient one-dimensional couette flow considering constant and time-dependent pressure gradients

This paperaims to determine the velocity profile, in transient state, for a parallel incompressible flow known as Couette flow. The Navier-Stokes equations were applied upon this flow. Analytical solutions, based in Fourier series and integral transforms, were obtained for the one-dimensional transient Couette flow, taking into account constant and time-dependent pressure gradients acting on the fluid since the same instant when the plate starts it´s movement. Taking advantage of the orthogonality and superposition properties solutions were foundfor both considered cases. Considering a time-dependent pressure gradient, it was found a general solution for the Couette flow for a particular time function. It was found that the solution for a time-dependent pressure gradient includes the solutions for a zero pressure gradient and for a constant pressure gradient.

Physics teachers initial education and professional performance: what do future teachers have to say?

This research deals with the discussion about Physics teachers’ undergraduate education and professional performance related to the knowledge acquired during this initial education. More specifically, we try to answer questions like: How do future teachers evaluate the knowledge acquired during their initial education as in terms of specific knowledge as pedagogical knowledge? What are their formative needs and future expectatives about professional performance and the school teaching environment? Data was constituted from a sample of 26 future high school physics teachers, one semester long, that were taking the supervised curricular training in a undergraduate Physics education program (called Licenciatura in Brazil), in São Paulo State public university. Besides the final report of this training, future teachers were asked to answer a questionnaire aiming to take their conceptions about their initial education program, their formative needs, future professional expectatives and high school teaching environment. According to the future teachers, the program they were about to finish was satisfactory in terms of Physics specific contents; however, about the pedagogical content knowledge and the pedagogical practice, they showed to be unsatisfied and insecure. The majority of the questionnaire responses demonstrated that they feel lack of teaching experience. Moreover, teachers emphasize other factors related to the future professional performance: possible difficulties to deal with students’ indiscipline, schools’ bad physical structure, limited number of Physics classes in high school level, lack of didactical laboratories and also they seem to be frightened that the expertise teachers do not be collaborative with the new ones. In this sense, the research outcomes shows the necessity of discussions about questions involving teachers knowledge, related to either, the Physics conceptual domain and the pedagogical one, since it matters directly to future teachers professional performance. Discussions in this sense can also help evaluation and restructuration of programs designed to initial and continuous teachers’ education.

Conceitos de didática: depoimentos de docentes universitários da área de Educação Física

Na pesquisa investigou-se como docentes universitários em Educação Física conceituam didática. Realizou-se revisão da literatura abordando história e conceituações da didática. Utilizando-se a técnica de entrevista e análise qualitativa, coletou-se e analisou-se depoimentos de treze docentes universitários oriundos do mestrado em Educação Física. Com o método de abordagem histórico constatou-se que a didática esteve articulada às tendências pedagógicas: tradicional, escola nova, tecnicista e progressista e é conceituada como disciplina, área de estudos e técnica de ensino. Como técnica pode ser entendida no sentido amplo, referindo-se a procedimentos de levar alguém a aprender algo e no sentido pedagógico apresenta os procedimentos atrelados à questões sócio-morais. Os depoimentos coletados revelaram que os docentes universitários entendem a didática no sentido amplo. Conclui-se que na formação destes docentes universitários a didática foi abordada apenas como técnica de ensino, apesar de sua trajetória histórica e a prática pedagógica estarem diretamente ligadas aos rumos da educação.
