Discute a participação política de jovens e a sua relação com a educação formal. Argumentando a favor de mais conhecimento e envolvimento dos jovens na política institucionalizada, busca analisar as oportunidades abertas pelas normativas da educação e pelas inovações produzidas nos legislativos do país para a inclusão, no contexto da educação escolar, da temática das instituições políticas e do Poder Legislativo.

Using second-order autocorrelation conception, a novel method and instrument for accurately measuring interval between two linearly polarized ultrashort pulses with real time were presented. The experiment demonstrated that the measuring method and instrument were simple and accurate (the measurement error <5 fs). During measuring, there was no moving element resulting in dynamic measurement error.

We consider canonical systems with singular left endpoints, and discuss the concept of a scalar spectral measure and the corresponding generalized Fourier transform associated with a canonical system with a singular left endpoint. We use the framework of de Branges’ theory of Hilbert spaces of entire functions to study the correspondence between chains of non-regular de Branges spaces, canonical systems with singular left endpoints, and spectral measures.
We find sufficient integrability conditions on a Hamiltonian H which ensure the existence of a chain of de Branges functions in the first generalized Pólya class with Hamiltonian H. This result generalizes de Branges’ Theorem 41, which showed the sufficiency of stronger integrability conditions on H for the existence of a chain in the Pólya class. We show the conditions that de Branges came up with are also necessary. In the case of Krein’s strings, namely when the Hamiltonian is diagonal, we show our proposed conditions are also necessary.
We also investigate the asymptotic conditions on chains of de Branges functions as t approaches its left endpoint. We show there is a one-to-one correspondence between chains of de Branges functions satisfying certain asymptotic conditions and chains in the Pólya class. In the case of Krein’s strings, we also establish the one-to-one correspondence between chains satisfying certain asymptotic conditions and chains in the generalized Pólya class.

A regulação da propaganda de medicamentos no Brasil incorpora quatro fragilidades: 1. A monitoração, fiscalização e punição de irregularidades são realizadas a posteriori do acometimento da infração (quando a população já foi submetida a risco sanitário); 2. As multas cobradas pela Anvisa têm valor irrisório frente aos investimentos do marketing farmacêutico; 3. Não há mecanismo que impeça que mesmo os valores irrisórios das multas sejam repassados aos preços dos produtos, onerando o consumidor; 4. A frase tida como de alerta - A PERSISTIREM OS SINTOMAS O MÉDICO DEVERÁ SER CONSULTADO - ao invés de conscientizar a população a respeito dos riscos da automedicação, estimula o uso de medicamentos sem receita, aconselhando a busca de um médico apenas no caso da persistência dos sintomas. Segundo dados da Anvisa e de estudos acadêmicos, 90% da publicidade exibida contém irregularidades. Assim, a RDC 102/2000 da Anvisa, que regulamenta o setor, se constitui em um aparente sistema de regulação, que beneficia o infrator e mantém a população sob risco. Este trabalho analisa o conceito e o uso dos mecanismos de marketing na busca de se elevar a comercialização de produtos farmacêuticos (no que se denomina produção de doenças), examina os conceitos de propaganda, medicamento, regulação e manipulação; percorre alguns estatutos internacionais referentes ao setor da publicidade de medicamentos (com foco nas diretivas da União Européia) e expõe a avaliação de organismos europeus de defesa do consumidor sobre o desempenho destas normas. Ao final, este estudo expõe as posições do setor regulado brasileiro (indústria, agências de publicidade e meios de comunicação) frente às posições de órgãos de defesa dos consumidores, da academia e da sociedade organizada no âmbito do SUS, para propor como alternativa um modelo regulador que supere as fragilidades do atual.

Over a number of years complaints have been made by various angling associations within the area of the Lancashire and Mersey and Weaver River Authorities about the unsatisfactory state of the fisheries in the Leeds/Liverpool Canal. Following upon discussions with the associations the Lancashire River Authority agreed to carry out an investigation into the fish species and their populations. The survey has extended over two years and it is hoped that the following information will be of value to all concerned. The canal is 127 miles in length when measured from the River Aire at Leeds to the docks at Liverpool. The survey was confined to two sections: i) That part of the canal which passes through the area of the Lancashire River Authority; and ii) 10 miles of that section which runs through the area of the Mersey and Weaver River Authority. The fish were sampled by electro-fishing, a 100 yard section of canal being sampled at each one mile interval. Water samples for chemical analysis were taken immediately prior to the commencement of fishing operations. The analyses were intended to demonstrate the quality of the water in which the fish were living at the time of the survey. Regular samples of the fauna and flora present in the canal were taken and examined in the fisheries laboratory of the Authority.

The purpose of this study was to compare the effects of Small-Sided Games (SSG) vs. Interval Training (IT) in soccer training on aerobic fitness and physical enjoyment in youth elite soccer players during the last 8 weeks of the season. Seventeen U-16 male soccer players (age = 15.5 +/- 0.6 years, and 8.5 years of experience) of a Spanish First Division club academy were randomized to 2 different groups for 6 weeks: SSG group (n = 9) and IT group (n = 8). In addition to the usual technical and tactical sessions and competitive games, the SSG group performed 11 sessions with different SSGs, whereas the IT group performed the same number of sessions of IT. Players were tested before and after the 6-week training intervention with a continuous maximal multistage running field test and the counter movement jump test (CMJ). At the end of the study, players answered the physical activity enjoyment scale (PACES). During the study, heart rate (HR) and session perceived effort (sRPE) were assessed. SSGs were as effective as IT in maintaining the aerobic fitness in elite young soccer players during the last weeks of the season. Players in the SSG group declared a greater physical enjoyment than IT (P = 0.006; ES = 1.86 +/- 1.07). Coaches could use SSG training during the last weeks of the season as an option without fear of losing aerobic fitness while promoting high physical enjoyment.
