The production of critical-reflexive narratives and their effect on nursing students' portfolios

The objective of this study is to analyze the process of producing reflexive narratives on nursing students' portfolios. This qualitative study performed an analysis of the portfolios of the class discipline Health Promotion in Primary Education, taught in the fourth semester of the Nursing Licensure Course. Results showed an initial predominance of descriptive records, with the incipient approach of theoretical aspects associated with the aspects regarding their experience. Further, in the group and experience discussions, there were narratives containing more critical and reflexive elements, with justifications for the described actions and the relationships with the theoretical-practical aspects studied in the class and in the course. In conclusion, there is a process of producing critical-reflexive narratives in portfolios that could include a summarized description, using common sense and idealization which allows for including the differences and the theoretical review.

Economia política da arte moderna II/ notas para uma sistematização provisória

Paradigma tradicional de excelência artesanal, com que meios pode a pintura responder à abstração do trabalho e à sua ordenação serial, inerentes à modernização capitalista? O texto presente busca sistematizar os momentos decisivos de um percurso que se estende de Manet (1832-1883) a Rothko (1903-1970). Constitui o capítulo conclusivo de uma investigação sobre a transformação crítica do modo de pintar em modo de fabricação, fundado na superação reflexiva da dicotomia entre trabalho intelectual e corporal, imposta historicamente à sociedade. Atualizada criticamente e assinalando um fecho possível do processo da arte moderna, a pintura de Rothko põe-se como a negação de todo aspecto individual da pintura e de unidade orgânica e monádica da obra. Alcança-se assim o último termo de um processo; termo que assinala o fim do ciclo da autonomia estética como forma ligada à liberdade do sujeito, idealizado como natureza desinteressada. Para o trabalho de resistência contra a aceleração da barbárie é fundamental doravante levar em conta os fatores de heteronomia supraindividuais que, se não logram controlar toda a produção, detêm a hegemonia na esfera da circulação.

Integrodifference model for blowfly invasion

We propose a stage-structured integrodifference model for blowflies' growth and dispersion taking into account the density dependence of fertility and survival rates and the non-overlap of generations. We assume a discrete-time, stage-structured, model. The spatial dynamics is introduced by means of a redistribution kernel. We treat one and two dimensional cases, the latter on the semi-plane, with a reflexive boundary. We analytically show that the upper bound for the invasion front speed is the same as in the one-dimensional case. Using laboratory data for fertility and survival parameters and dispersal data of a single generation from a capture-recapture experiment in South Africa, we obtain an estimate for the velocity of invasion of blowflies of the species Chrysomya albiceps. This model predicts a speed of invasion which was compared to actual observational data for the invasion of the focal species in the Neotropics. Good agreement was found between model and observations.

Central catheter dressing in a simulator: the effects of tutor's assistance or self-learning tutorial

Aims: to compare the performance of undergraduate students concerning semi-implanted central venous catheter dressing in a simulator, with the assistance of a tutor or of a self-learning tutorial. Method: Randomized controlled trial. The sample consisted of 35 undergraduate nursing students, who were divided into two groups after attending an open dialogue presentation class and watching a video. One group undertook the procedure practice with a tutor and the other with the assistance of a self-learning tutorial. Results: in relation to cognitive knowledge, the two groups had lower performance in the pre-test than in the post-test. The group that received assistance from a tutor performed better in the practical assessment. Conclusion: the simulation undertaken with the assistance of a tutor showed to be the most effective learning strategy when compared to the simulation using a self-learning tutorial. Advances in nursing simulation technology are of upmost importance and the role of the tutor in the learning process should be highlighted, taking into consideration the role this professional plays in knowledge acquisition and in the development of critical-reflexive thoughts and attitudes.

A produção de narrativas crítico-reflexivas nos portfólios de estudantes de enfermagem

Esta investigação visou analisar o processo de construção das narrativas reflexivas em portfólios de estudantes de enfermagem. Trata-se de um estudo qualitativo, que analisou os portfólios da disciplina Promoção da Saúde na Educação Básica, ministrada no quarto semestre do curso de Licenciatura em Enfermagem. Os resultados indicaram a predominância inicial de registros descritivos, com a incipiente abordagem de aspectos teóricos articulados aos aspectos vivenciais. Com o transcorrer das discussões em grupo e das vivências foram apresentadas narrativas com elementos mais críticos e reflexivos, com justificativas das ações descritas e relações com aspectos teórico-práticos estudados na disciplina e no curso. O estudo conclui que há um processo de produção das narrativas crítico-reflexivas em portfólios que pode incluir descrição sintética, senso comum, idealização, e que, de modo singular, possibilita a inclusão do outro, das diferenças e de revisão teórica.

Talking bodies: nonverbal behavior in the assessment of depression severity

BACKGROUND: Evaluations of clinical depression are traditionally based on verbal information. Nonverbal expressive behavior, however, being associated with a person's reflexive responses, may reveal negative emotional or social processes that are not under complete control of the patients. However, investigations of nonverbal behavior in the evaluation of depressed patients are still scarce. This study examines the nonverbal behaviors of a group of Brazilian patients, associating their nonverbal behavior with severity of depression. METHODS: Forty depressed patients were evaluated at baseline (T0) and after a two-week transcranial direct current stimulation treatment (T1), according to rating scales and through a 21-category Ethogram for assessment of the frequency of nonverbal behaviors displayed during an interview. RESULTS: Behaviors that were related to negative feelings and social disinterest decreased with corresponding clinical improvement and were associated with increased severity of symptoms at T0 and greater negative affect and dissatisfaction at T1. Pro-social behaviors were associated with milder symptoms at T0 and increased after treatment. Facial, head and hand expressive movements stood out as important indicators because of their associations with severity of depression. LIMITATIONS: Duration of behaviors was not assessed and there was not a healthy control group with which to compare the findings. CONCLUSIONS: These results support the usefulness of nonverbal behavior as an evaluation technique in the assessment of clinical depression.
