Práticas educativas de genitores e professores e repertório comportamental infantil / Educational practices of parents and teachers and children's behavioral repertoire

O objetivo deste estudo é descrever, a partir de múltiplos instrumentos e informantes, o repertório comportamental (habilidades sociais e problemas de comportamento) de quatro crianças de 6 a 7 anos, duas de cada sexo, e as práticas educativas positivas (habilidades sociais educativas) e negativas de quatro mães, quatro pais e duas professoras dos primeiros anos do Ensino Fundamental. Foram utilizados na coleta de dados instrumentos de relato e protocolo de observação de interações genitores-criança a partir de situação de brincadeira. Os resultados reafirmam que práticas positivas estão relacionadas à baixa frequência de problemas de comportamento e presença de habilidades sociais e, ao contrário, práticas negativas estão relacionadas a problemas de comportamento. A literatura tem encontrado tais relações entre pais e filhos e com a presente pesquisa nota-se o mesmo no que se refere à interação professor-aluno.

The aim of this study is to describe, from multiple instruments and informants, the behavioral repertoire (social skills and behavioral problems) of four children aged six to seven years old, two of each sex, and positive educational practices (educational social skills) and negative practices of four mothers, four fathers and two teachers from the first years of elementary school. Data collection instruments and protocol for observing the parent-child interactions, from a situation of play, were used. The results reaffirm that positive practices are related to the low frequency of behavioral problems and the presence of social skills, and, on the contrary, negative practices are related to behavioral problems. The literature has found such relationships between parents and children and with the present research the same can be noticed with regard to teacher-student interaction.

Sleep patterns and sleepiness among young students: A longitudinal study before and after admission as trainees and apprentices.

In developing countries, youngsters start to work during the high school years. Several studies have shown the difficulties associated with double shift, i.e. to work and study concomitantly, and its negative health consequences. Work and study time, as social synchronizers, have significant effects on the sleep-wake cycle (SWC). The purpose of this study was to evaluate sleep patterns and sleepiness in young students before and after entering the workforce as apprentices or trainees. Participants were 40 adolescents (26 males), 15-18 years old (mean = 15.8 years old) engaged in a first-job program at a non-governmental organization (NGO) while attending evening high school in the outskirts of the city of São Paulo, Brazil. The participants wore actigraphs (Ambulatory Monitoring, Inc.) and registered subjective sleepiness on KSS (Karolinska Sleepiness Scale) along 7 consecutive days, before and after admission to the job. Descriptive analyses were performed, and the variables were tested by means of the t-test and repeated measures ANOVA taking factors day of the week and time of the day into consideration. The participants' sleep duration on weekdays exhibited significant difference before and after starting work (F = 4.55; p = 0.04); the mean sleep duration was 492 min (SD = 44 min) before admission to the job to decrease to 405 min (SD = 58 min) after starting work. The mid-sleep time exhibited significant difference on weekdays before and after starting work (04:57 h; SD = 45 min versus 03:30 h; SD = 54 min; F = 4.91; p = 0.03). Finally, also sleepiness on weekdays (F = 6.41; p = 0.04) and at the waking time (F = 10.75; p < 0.01) exhibited significant difference before and after admission to the job. This article emphasizes the fact that social synchronizers like working during the day and studying in the evening changed the participants' SWC and were associated with sleep restriction. Brazilian governmental incentives notwithstanding, simultaneous performance of several activities by young workers should be considered as an occupational health hazard. Employment policies targeting young workers should take the dual shift - study and work - and its effects on the sleep-wake cycle into account.
