Futebol brasileiro: uma análise comparativa das fórmulas de disputa do campeonato brasileiro da série A nos últimos 15 anos (1995-2010)

In Brazil, the football is more than just a sport, it's a passion and part of country's DNA almost a century ago. By this prerogative the club national championship, nowadays known as Brazilian Championship and organized by Brazilian Football Confederation, it is a mark in this modality. During the soccer history, were made several changes of nomenclature, rules and dispute mode, that generated many controversies, contributing for discussing about credibility of the championship. There were many changes about dispute mode, alternating the mixed mode (eliminatory + classificatory and vice versa) and a dispute mode based on classification. This research aimed to described and to analyzed the changes that have occurred in dispute types of the Brazilian Championship, series A, in the last 15 years (1995 to 2010). It was analyzed each edition, with data like average of public, matches and participants number, period that the championship was conducted, beyond the dispute mode. In the last 15 years, have been used five different types and it was observed that the current mode to consecutive points is the most appropriate, because this mode showed the best public average, greater coherence to elect the competition champion and this mode also encouraged the clubs about planning, organization and professional management. This issues contributed to a significant improvement in quality of Championship

A participação dos movimentos sociais na disputa pela água no Pontal do Paranapanema

É da disputa histórica pela posse da terra no Pontal do Paranapanema e dos conflitos daí desdobrantes que vem à tona as cifras marcantes das terras improdutivas e devolutas e, mais ainda, o descrédito em relação à Reforma Agrária e a negativa a qualquer possibilidade de acesso à terra, tais como a política de assentamentos em vigência, mas totalmente enfraquecida e desprestigiada. É nesse cenário que a apropriação da água ou sua privatização comparece como preocupação. A iniciativa do Movimento dos Trabalhadores Rurais Sem Terra (MST) em implantar um projeto de piscicultura, via o sistema tanques-rede para a subsistência e também como fonte de renda, nas águas represadas pelas UHEs enfrentará uma série de empecilhos e travagens de ordem burocrática, política e econômica. Além de despertar para a importância de discutir o a privatização e a mercantilização da água no século XXI, e a expansão da aquicultura no Brasil nos últimos anos, pretendemos identificar e analisar as dinâmicas espaciais e as disputas pelo acesso à água no Pontal do Paranapanema

Disputa por fêmeas entre machos da aranha marrom Loxosceles gaucho (Araneae: Sicariidae)

O comportamento agonístico de machos de Loxosceles gaucho (“aranha-marrom”), sem assimetrias de dominância de território e experiência prévia, minimizando-se a diferença de tamanho, foi avaliado em presença do recurso fêmea. Reavaliamos a importância da diferença de tamanho e pudemos sugerir o papel relevante da reação do animal a ambiente novo (primeiro a movimentar-se) na disputa por fêmea reprodutiva. Vimos que a competição por fêmeas se resolve por disputas pouco intensas, ou até mesmo sem qualquer interação observável entre os machos. Os dados mostram uma disputa que prioriza a economia de energia e impõe menor risco de danos físicos aos animais, característica possivelmente associada ao hábito gregário de L. gaucho.

Escolas públicas no campo: retrospectiva e perspectivas em um contexto de projetos políticos em disputa

In present article, we present reflections on the process of closing public schools in the countryside in Brazil. Through bibliographical survey, as well as documental research, we carried out a retrospective analysis of the historical moment in which the implementation of policies of mass education directed to people living in rural areas occurs. We have also sought to raise socio-political-economic aspects of the moment in which the process of closing these schools is intensified. The results obtained suggest possible implications of this closure policy, in addition to indicating some of the challenges posed to the public policy of education in the country; for example, the Brazilian federal context and the budget limitations imposed to subnational governments with regard to the funding of school education, particularly in relation to small municipalities and/or municipalities with low tax revenues. This situation quite often occurs because these municipalities present reduced budgets, depending largely on transfers of financial resources from other spheres of the Government, either federal or state, the so-called intergovernmental budgetary transfers; namely, the Municipalities Participation Fund. Such issues demand the resumption of debates about the federative pact, in particular with regard to fiscal federalism, given that the financial capacity of each subnational government is crucial to the implementation of educational policies.

A descentralização político-administrativa no Brasil: um estudo sobre a disputa entre os municípios de Caiuá e Marabá Paulista pela Decasa Açúcar e Álcool a partir das escalas geográficas de análise

This work has as main objetive to analyze fiscal/tax collection of municipalities after the political-administrative decentralization in Brazil and its new role in this scenario, bringing up the competition for Decasa Sugar and Alcohol between the municipalities of Caiuá and Maraba Paulista in the context of expansion sugarcane cultivation in the Presidente Prudente Geographic Micro Region. The analysis has considered the geographic scales, in order to highlight the power relations on local/regional territory, determined by the Agroenergy Policy Guidelines in Brazil (2006-2011). The two municipalities have from the point of view economic dynamics, irrelevence, proven through the São Paulo Index of Social Responsibility (IPRS), maximizing the importance of the constitutional transfers, such as Participation Fund of Municipalities (FPM). Given this situation, we analyze the four taxes raised by the experts as the most impactful for municipal tax collection before the presence of sugarcane activity: the Territorial Urban Property Tax (IPTU), the Tax on Services of any Nature (ISSQN), the Tax Vehicles owned Motor (IPVA) and the Operations tax on the Circulation of Goods and on Transport Services Rendered Interstate and Intermunicipal (ICMS). It was verified, that only the ISSQN can be seen as an indicator increase in fiscal/tax collection before the presence sugarcane activity...

Lei de Meios argentina: entre o velho e o novo na disputa pelo direito à comunicação

A pesquisa analisa o novo marco regulatório da comunicação da Argentina, a Lei n° 26.522/2009 de Serviços de Comunicação e Audiovisual (LSCA). O texto é referência reguladora emblemática e contemporânea para os campos de estudos da Comunicação, das Políticas Públicas e da Economia Política da Comunicação na América Latina. O caráter original dessa legislação reside na aproximação de uma concepção inovadora do direito à comunicação e na atribuição de um novo papel regulador reservado ao Estado. A criação de uma nova arquitetura institucional para o desenho das políticas de comunicação, o estabelecimento de limites de propriedade para empresas e grupos da radiodifusão e a divisão do espectro radioelétrico em partes iguais para operadores privados, estatais e privados sem fins de lucro são objetos de especial atenção. Nesse sentido, são analisadas as premissas normativas da LSCA e os obstáculos à sua implantação. O processo de elaboração e implantação dessa nova legislação é inseparável do momento político e da correlação de forças políticas do país e de um fenômeno comum na América Latina desde a redemocratização: a emergência da sociedade civil e a luta pela difusão dos direitos de cidadania. A pesquisa aponta tensões entre politicas públicas progressistas e velhos costumes impregnados no Estado, como o fortalecimento de grupos de mídia próximos ao governo de turno e o uso oficialista dos canais de comunicação estatais. Assim, a LSCA revela baixo grau de materialização, a despeito de representar um avanço normativo, institucional e político chave para o país e a região na perspectiva da democratização da comunicação

Intelectuais brasileiros em disputa pela Escola Nova na década de 1930

In the first decades of the last century, Brazilian intellectuals played an im- portant role in the new configuration to the country reached. Brazil had then passed by rapid process of moderniza- tion. The educational field was place of contention between different currents of intellectuals. The idea was to create a new society through what is called the New School. In Brazil, unlike in Europe, most of the population had no access to school. Therefore, the New School was not privileged to critique existing school system, but the actual construction of the large Brazilian childhood schooling. Thus, we crea- ted libraries in teaching urban school groups, with the aim of improving the training of primary school teachers in the pedagogical ideas of the New School. This work has for objective to understand the conflicts among Brazi- lian intellectuals on the list of recommended readings for teacher training schools in the first half of the twentieth century. This paper presents an exam- ple of this intellectual dispute through the analysis of a Brazilian school li- brary copy of the 1930s.

Chromosome painting in three-toed sloths: a cytogenetic signature and ancestral karyotype for Xenarthra

Background: Xenarthra (sloths, armadillos and anteaters) represent one of four currently recognized Eutherian mammal supraorders. Some phylogenomic studies point to the possibility of Xenarthra being at the base of the Eutherian tree, together or not with the supraorder Afrotheria. We performed painting with human autosomes and X-chromosome specific probes on metaphases of two three-toed sloths: Bradypus torquatus and B. variegatus. These species represent the fourth of the five extant Xenarthra families to be studied with this approach. Results: Eleven human chromosomes were conserved as one block in both B. torquatus and B. variegatus: (HSA 5, 6, 9, 11, 13, 14, 15, 17, 18, 20, 21 and the X chromosome). B. torquatus, three additional human chromosomes were conserved intact (HSA 1, 3 and 4). The remaining human chromosomes were represented by two or three segments on each sloth. Seven associations between human chromosomes were detected in the karyotypes of both B. torquatus and B. variegatus: HSA 3/21, 4/8, 7/10, 7/16, 12/22, 14/15 and 17/19. The ancestral Eutherian association 16/19 was not detected in the Bradypus species. Conclusions: Our results together with previous reports enabled us to propose a hypothetical ancestral Xenarthran karyotype with 48 chromosomes that would differ from the proposed ancestral Eutherian karyotype by the presence of the association HSA 7/10 and by the split of HSA 8 into three blocks, instead of the two found in the Eutherian ancestor. These same chromosome features point to the monophyly of Xenarthra, making this the second supraorder of placental mammals to have a chromosome signature supporting its monophyly.

Variable patterns of Y chromosome homology in Akodontini rodents (Sigmodontinae): a phylogenetic signal revealed by chromosome painting

The Akodontini is the second most speciose tribe of sigmodontine rodents, one of the most diverse groups of neotropical mammals. Molecular phylogenetic analyses are discordant regarding the interrelationships of genera, with low support for some clades. However, two clades are concordant, one (clade A) with Akodon sensu strictu (excluding Akodon serrensis), "Akodon" serrensis, Bibimys, Deltamys, Juscelinomys, Necromys, Oxymycterus, Podoxymys, Thalpomys and Thaptomys, and another (clade B) with Blarinomys, Brucepattersonius, Kunsia, Lenoxus and Scapteromys. Here, we present chromosome painting using Akodon paranaensis (APA) Y paint, after suppression of simple repetitive sequences, on ten Akodontini genera. Partial Y chromosome homology, in addition to the homology already reported on the Akodon genus, was detected on the Y chromosomes of "A." serrensis, Thaptomys, Deltamys, Necromys and Thalpomys and on Y and X chromosomes in Oxymycterus. In Blarinomys, Brucepattersonius, Scapteromys and Kunsia, no APA Y signal was observed using different hybridization conditions; APA X paint gave positive signals only on the X chromosome in all genera. The Y chromosome homology was variable in size and positioning among the species studied as follow: (1) whole acrocentric Y chromosome in Akodon and "A." serrensis, (2) Yp and pericentromeric region in submetacentric Y of Necromys and Thaptomys, (3) pericentromeric region in acrocentric Y of Deltamys, (4) distal Yq in the acrocentric Y chromosome of Thalpomys and (5) proximal Yq in the acrocentric Y and Xp in the basal clade A genus Oxymycterus. The results suggest that the homology involves pairing (pseudoautosomal) and additional regions that have undergone rearrangement during divergence. The widespread Y homology represents a phylogenetic signal in Akodontini that provides additional evidence supporting the monophyly of clade A. The findings also raise questions about the evolution of the pseudoautosomal region observed in Oxymycterus. The Y chromosomes of these closely related species seem to have undergone dynamic rearrangements, including restructuring and reduction of homologous segments. Furthermore, the changes observed may indicate progressive attrition of the Y chromosome in more distantly related species.

Influence of artificial accelerated ageing on the colour stability of paints used for ocular prosthesis iris painting

Objectives: To evaluate the colour stability of paints used for ocular prosthesis iris painting submitted for accelerated artificial ageing (AAA). Materials and methods: Forty specimens of acrylic resin for sclera (16 x 2 mm) were made and separated into eight groups (n = 10) according to the type of paint (gouache, GP; oil, OP; acrylic AP; and composite resin for characterisation, CR) and the colours used (blue/brown). After drying (72 h), a new layer of colourless acrylic resin was applied and the initial colour readout was performed (Spectrophotometer PCB 6807). New colour readouts were performed after AAA, and Delta E was calculated. Results: Statistical analysis (two-way ANOVA-Bonferroni, p < 0.05) demonstrated that the brown colour showed lower Delta E means in comparison with the blue colour, with statistically significant difference for AP only. Blue colour showed no statistically significant difference with regard to the type of paint used. Brown AP showed lower Delta E than the other groups, with significant difference for OP and GP. GP showed greater alteration in Delta E for the brown colour, being statistically similar only to OP. Conclusions: Only the AP group for brown pigment shows clinically acceptable values for colour stability after AAA.
