Desempenho escolar da criança vitimizada encaminhada ao fórum judicial

O objetivo do estudo foi caracterizar o desempenho escolar da criança vítima de violência doméstica atendida no Fórum Judicial. Participaram do estudo 20 crianças vitimizadas comparadas com seus pares da mesma sala de aula, mesmo sexo e mesma faixa etária, mas sem histórico de violência doméstica, suas respectivas mães e professoras. As crianças responderam ao Teste de Desempenho Escolar, Inventário de Estilos Parentais e ao Teste de Raven (Escala Especial) e apresentaram o caderno escolar. As mães responderam a uma entrevista e a Escala de Táticas de Conflitos Revisada (CTS-2). As professoras apresentaram sua opinião sobre o desempenho acadêmico dos participantes. Os dados obtidos mostraram que a criança vitimizada tem desempenho escolar inferior ao grupo controle. Os resultados da CTS-2 indicaram que a maioria das crianças vitimizadas estava exposta à violência conjugal. O estudo mostrou que, além da violência doméstica direta e indireta, tais crianças estavam expostas a outros fatores de risco, tais como, pobreza, baixa escolaridade materna e uso de álcool e/ou droga por familiares.

Desempenho cognitivo-linguístico de escolares com distúrbio de aprendizagem

O estudo tem como objetivo caracterizar e comparar o desempenho cognitivo-linguístico de escolares com distúrbio de aprendizagem com escolares com bom desempenho acadêmico. Participaram 40 escolares de 8 a 12 anos de idade, de 2ª a 4ª séries do Ensino Fundamental de escolas municipais da cidade de Marília - SP, divididos em GI (escolares com bom desempenho acadêmico) e GII (escolares com distúrbio de aprendizagem). Como procedimento foi utilizado o Teste de Desempenho Cognitivo-Linguístico, versões coletiva e individual. Os resultados evidenciaram desempenho superior do GI em relação ao GII nas habilidades de leitura, escrita, velocidade de processamento, processamento auditivo e visual. Concluiu-se que o desempenho inferior do GII nas habilidades indica uma limitação no desempenho linguístico desses escolares se comparados com os do GI, exceto na habilidade de consciência fonológica, em que, os grupos apresentaram dificuldades semelhantes, sugerindo que essa dificuldade não seja específica de escolares com distúrbio de aprendizagem.

Effects of egg storage time on spread of hatch, chick quality, and chick juvenile growth

A total of 1,800 incubating eggs produced by a commercial flock of Cobb broiler breeders was used to determine the effects of storage duration (3 or 18 d) on spread of hatch and chick quality. Chick relative growth (RG) at the end of 7 d of rearing was also determined as a measure of the chick performance. Chick quality was defined to encompass several qualitative characteristics and scored according to their importance. Eggs stored for 3 d hatched earlier than those stored for 18 d (P < 0.05). Hatching was normally distributed in both categories of eggs, and the spread of hatch was not affected by storage time (P = 0.69). Storage duration of 18 d reduced the percentage of day-old chick with high quality as well as average chick quality score (P < 0.05). RG varied with length of egg storage, quality of day-old chick, and the incubation duration (P < 0.05). Eighteen-day storage of eggs not only resulted in longer incubation duration and lower quality score but also depressed RG. Chick quality as defined in this study was correlated to RG and storage time. It was concluded that day-old chick quality may be a relatively good indicator of broiler performance. The results suggest however that in order to improve performance prediction power of chick quality, it would be better to define it as a combination of several qualitative aspects of the day-old chick and the juvenile growth to 7 d.

Relationships and significance of lactate minimum, critical velocity, heart rate deflection and 3 000 m track-tests for running

The running velocities associated to lactate minimum (V-lm), heart rate deflection (V-HRd), critical velocity (CV), 3000 M (V-3000) and 10000 m performance (V-10km) were compared. Additionally the ability of V-lm and VHRd on identifying sustainable velocities was investigated.Methods. Twenty runners (28.5 +/- 5.9 y) performed 1) 3000 m running test for V3000; 2) an all-out 500 in sprint followed by 6x800 m incremental bouts with blood lactate ([lac]) measurements for V-lm; 3) a continuous velocity-incremented test with heart rate measurements at each 200 m for V-HRd; 4) participants attempted to 30 min of endurance test both at V-lm(ETVlm) and V-HRd(ETVHRd). Additionally, the distance-time and velocity-1/time relationships produced CV by 2 (500 m and 3000 m) or 3 predictive trials (500 m, 3000 m and distance reached before exhaustion during ETVHRd), and a 10 km race was recorded for V-10km.Results. The CV identified by different methods did not differ to each other. The results (m(.)min(-1)) revealed that V-.(lm) (281 +/- 14.8)< CV (292.1 +/- 17.5)=V-10km (291.7 +/- 19.3)< V-HRd (300.8 +/- 18.7)=V-3000 (304 +/- 17.5) with high correlation among parameters (P < 0.001). During ETVlm participants completed 30 min of running while on the ETVHRd they lasted only 12.5 +/- 8.2 min with increasing [lac].Conclusion. We evidenced that CV and Vim track-protocols are valid for running evaluation and performance prediction and the parameters studied have different significance. The V-lm reflects the moderate-high intensity domain (below CV), can be sustained without [lac] accumulation and may be used for long-term exercise while the V-HRd overestimates a running intensity that can be sustained for long-time. Additionally, V-3000 and V-HRd reflect the severe intensity domain (above CV).

Application of ARX neural networks to model the rate of penetration of petroleum wells drilling

Bit performance prediction has been a challenging problem for the petroleum industry. It is essential in cost reduction associated with well planning and drilling performance prediction, especially when rigs leasing rates tend to follow the projects-demand and barrel-price rises. A methodology to model and predict one of the drilling bit performance evaluator, the Rate of Penetration (ROP), is presented herein. As the parameters affecting the ROP are complex and their relationship not easily modeled, the application of a Neural Network is suggested. In the present work, a dynamic neural network, based on the Auto-Regressive with Extra Input Signals model, or ARX model, is used to approach the ROP modeling problem. The network was applied to a real oil offshore field data set, consisted of information from seven wells drilled with an equal-diameter bit.

Hallazgos de neuroimagen y desempeño ortográfi co de estudiantes con trastorno por défi cit de atención con hiperactividad según la semiología de los errores

Aim: To characterize, compare and classify the performance of students with attention deficit-hyperactivity disorder (ADHD) according to the semiology of errors and to describe the neuroimaging findings in these students. Methods: We evaluated 36 primary school boys and girls aged between 8 and 11 years old in the 3 rd to 5 th grades. The children were divided in two groups. Group I consisted of 18 students with an interdisciplinary diagnosis of ADHD (60% boys and 40% girls). Group II consisted of 18 children with good academic performance, paired by gender, age and grade with children in group I. The collective and individual versions of the Pro-ortografia spelling tests were applied. Results: Statistically significant differences were found in almost all the tests of the individual and collective versions of the spelling evaluation, with children with ADHD showing a higher average number of errors. Neuroimaging examinations indicated that 81% of the students in GI showed hypoperfusion in the frontal lobe, 7% had hypoperfusion of the thalamus and basal ganglia, 6% showed hypoperfusion in the basal ganglia only and 6% showed hypoperfusion in the left and right frontal lobes. Conclusions: Children with ADHD demonstrated poorer knowledge of the use of spelling rules in Brazilian Portuguese, which could be related to changes in blood flow in the frontal lobe, parietal lobe, thalamus and basal ganglia. These changes could cause a lack of attention, affecting phonological working memory and the planning of writing. © 2011 AELFA.

Análise comparativa das relações entre ensino e aprendizagem por professores e alunos

In this research we identified and compared the representations of teachers and students on teaching and learning. The objective was to determine which aspects of these representations correspond to subjects and if they differ between students with high and low academic performance. Data collection was organized through a semi-structured interview. The study included twenty teachers and forty students in the 5th year of elementary school municipal public metropolitan region of Campinas. The responses from the interviews were categorized and analyzed by using the Fisher exact test, chi-square and Proportions. The results show that teachers and students present a partial view of the factors involved in teaching and learning. The learning process is understood as an individual and social factor. Teachers and students with high performance positively represent the environment of the classroom, unlike the students with lower academic performance.
