O fenômeno bullying compreende todas as formas de atitudes agressivas, intencionais e repetidas (de maneira insistente e perturbadora), que ocorrem sem motivação evidente e de forma velada, sendo adotadas por um ou mais estudantes contra outro(s), dentro de uma relação desigual de poder. Este tipo de violência se manifesta, sutilmente, sob a forma de brincadeiras, apelidos, trotes, gozações e agressões físicas.Com relação às maneiras que os alunos se envolvem com o bullying, eles são classificados em alvos, alvos/autores, autores e testemunhas.Considera-se, como uma primeira estratégia, a identificação desses casos por parte do corpo docente de educação física. Para a identificação, o primeiro ponto é analisar quais papéis os alunos representam, ou seja, como os alunos se envolvem com o bullying. Uma ...

The model predicts that, relative to proportional elections, ma-joritarian elections reduce government spending because they reduce party fragmentation and, therefore, the incidence of coalition governments. Party fragmentation can persist under majoritarian rule if party supporters are unevenly distributed across electoral districts. Economic and political data, from up to 50 post-war parliamentary democracies, strongly support our joint predictions from the electoral rule, to the party system, to the type of government, and to government spending.

Research paper thumbnail of Exact Maximum Likelihood Estimation of Stationary Vector ARMA Models

A new and efficient procedure far evaluating the exact likelihood function is presented. This method puts together a set of useful features which can only be found separately in currently available algoritluns. A procedure for maximizing the exact likeliliood function, which takes full advantage of the properties offered by the evaluation algorithm, is also considered, Combining these two procedures, a * This paper summarizes the author's doctoral

We combine these results with preliminary thermobarometric estimates and existing data to place constraints on the timing and duration of the Brasiliano-Pan-African Orogeny in northeastern Brazil and on the subsequent late-to post-orogenic history. The Alcantil orthogneiss contains a complex zircon population, but the youngest concordant analyses yielded an age of 632 AE 17 Ma (2s). These grains have low Th/U ratios (<0.1), and the age of 632 Ma is therefore interpreted as dating the metamorphic event responsible for the acquisition of the gneissic fabric. In the Caruaru biotite amphibole orthogneiss, concordant analyses provided an age of 618 AE 4 Ma (2s), which we relate to emplacement of the pro-tolith of the Caruaru orthogneiss. Together with available UePb data from the literature, the 632e600 Ma age range is regarded as dating development of a regional flat-lying foliation coeval with high-grade metamorphism (upper amphibolite facies conditions). The 586 AE 3 Ma age (2s) of the Panelas pluton is similar to those of other granitic plutons associated with a voluminous plutonism of high-K calc-alkaline to shoshonitic nature that occurred at 590e580 Ma. This plutonism slightly predated or was synchronous with development of large strike-slip shear zones. Amphibole grains yielded 40 Are 39 Ar ages ranging from 584 AE 4 Ma to about 530 Ma, suggesting that regional temperatures remained near the closing temperature of this mineral (z500 C) for a long time. Most 40 Ar-39 Ar biotite ages range from 552 to 533 Ma, but two samples yielded plateau ages of 519 AE 5 Ma and 509 AE 5 Ma. The inferred rather slow cooling of the studied region possibly reflects low rates of unroofing, allowing persistence of a protracted thermal anomaly caused by the massive injection of magmas at the end of the Neoproterozoic.
