Identifying parental practices contingent to the behavior of children is important to support interventions. This study compares parental disciplinary practices with the behavior of children in a clinical group with behavioral problems (n = 27) and of a group of children without behavioral problems (n = 26). The criterion to assign children in the clinical and non-clinical groups was obtained from the Child Behavior Checklist (CBCL). Information concerning parents-children interaction was obtained through the application of the Parental Educative Social Skills Interview Script (RE-HSE-P), which evaluates positive and negative educational practices, context, behavioral problems and children's social skills. Qualitative and quantitative analyses (Mann Whitney's test) were used in the groups' comparison. The results indicate that behaviors that differentiate between the clinical and non-clinical groups are mainly those related to positive educational practices and children's social skills.

The present article, which is one study among others, seeks to understand practices and tactics of day-to-day school, spanning and being spanned by three studies in Mathematics education. The diversity of scenes, people and strategies used by actors in everyday school, considered from the theoretical perspectives of Foucault and Deleuze, shed light on the ways Mathematic alphabetization takes place and evidence regarding what is present in the black box of school culture, in a constant problematization about what a school can do. Maps are presented that establish cartographies, revealing smooth and striated territories, on a path created by the research done in those schools, where life is always invented.

The aim of this study was to evaluate the effect of different irrigation depths and nitrogen levels on the agronomic characteristics of inoculated cowpea. The experiment was arranged in splitplots, with the levels of nitrogen in the plots and the depth of irrigation in the splitplots, in a randomized block design, with two repetitions. The irrigation depth corresponded to 578 mm (L1), 512 mm (L2), 429 mm (L3), 299 mm (L4) and 240 mm (L5), and the nitrogen levels of 0, 30, 60 and 90 kg ha-1 of N. The nitrogen levels showed significant effect on the yield components of cowpea. The irrigation depth showed significant effects on productivity of bean cowpea, with the depth of 426.21 mm estimated for obtaining the maximum productivity of 2820.03 kg ha-1.

The aim was to evaluate levels and forms of application of potassium on the agronomic and alimentary characteristics of corn used for silage. The experiment was carried out at UNIFENAS during the agricultural year of 2008/2009. Fertilization at planting and sowing was performed manually using 120kg ha-1 P2O5 and 30kg ha-1 N, the potassium being applied according to the treatments. The experimental design used was of randomized blocks in a 4 x 2 factorial arrangement with four replications, using four amounts (0; 60; 90 and 120 kg ha-1) and two formsof application of K (100% at planting and 50% at sowing+50% coverage). The interaction between the factors of amount and forms of application of the potassium was not significant (p>0.05) for the variables studied: the main effect of each factor was then investigated. There was no effect (p>0.05) for K levels on the percentage of drymatter (DM) and bedded plants, DM and grain productivity and grain participation in the mass. The highest grain yield was obtained when using K at planting (p<0.05). High doses of potassium did not produce changes in DM, percentage of bedded plants, DM production, grain yield or grain percentage of the plant. The different levels and forms of application of potassium do not alter the alimentary characteristics of corn silage.

It is notorious that the cluster formation is a possibility for micro, small and medium companies to become more competitive. This research therefore aims to analyze leading practices for product innovation in companies belonging to the cluster of Votuporanga, which is the largest furniture industry in production and exporting of São Paulo state. Therefore, we conducted a survey research and data were collected from 61 furniture companies in the region of Votuporanga-SP. Among the main results it is observed that the incremental innovation of products is a central characteristic between the companies in cluster and there is little collaboration for the joint development of products from these companies with external agents such as research institutes, universities and even suppliers.
