Para análise da questão da gestão política do processo de inclusão escolar, este artigo aborda o movimento da rede municipal de São Paulo em direção à uma escola inclusiva através da oferta de respostas educativas aos alunos com necessidades educacionais especiais. Assim, descreve o Programa Inclui, em andamento na rede municipal de ensino, que busca organizar, através de projetos, a construção e consolidação de um sistema inclusivo, na perspectiva de estar articulado com as práticas e ações político-pedagógicas que ocorrem desde a educação infantil ao ensino médio e se concentra nas ações necessárias para o atendimento às necessidades educacionais especiais para que se garanta a desejável relação entre educação comum e especial no enfrentamento das dificuldades do processo de ensino e aprendizagem daqueles que precisam de recursos, técnicas, metodologias diferenciadas para que sua trajetória escolar esteja garantida, no cotidiano, assim como está garantida no aspecto legal.

Objetivou-se estimar os parâmetros e avaliar as tendências genética e fenotípica para a produção de leite ajustada aos 305 dias em bubalinos da raça Murrah nascidos no período de 1982 a 2003. Os parâmetros e os valores genéticos foram estimados por meio do aplicativo MTDFREML. A tendência genética foi estimada pela regressão dos valores genéticos sobre o ano de nascimento, por duas metodologias: 1) regressão linear; 2) regressão por meio de polinômios articulados utilizando-se a função de alisamento spline. A herdabilidade e a repetibilidade estimadas foram de 0,20 e 0,36, respectivamente. As tendências (regressão linear) fenotípica e genética foram significativas e iguais a 32,86 e 0,85 kg/ano, respectivamente. O ganho genético foi positivo, constatando-se instabilidade na tendência genética no decorrer dos anos, com períodos de ganhos e outros de perdas genéticas. A maior parte do ganho observado em alguns períodos resultou de melhorias nas condições ambientais.

Material from a new titanosaur from the Bauru Basin (Bauru Group), Brazil is described and compared with well-known titanosaurs. Adamantisaurus mezzalirai gen. et sp. nov. is based on six articulated anterior caudal vertebrae and two haemapophyses collected from the Adamantina Formation, which is considered to be Campanian-Maastrichtian? in age. Adamantisaurus mezzalirai is characterized by the following combination of characteristics: anterior caudal vertebrae with straight or slightly backwardly-projecting neural spines with strongly expanded distal ends, stout prespinal lamina, very wide pre- and postzygapophyseal articular facets, and concave postzygapophyseal articular facets on anterior caudal vertebrae. Although our cladistic analysis has produced equivocal results, Adamantisaurus mezzalirai shares with DGM 'Series B' (Peiropolis titanosaur) and Aeolosaurus the presence of postzygapophyses with concave articular facets, and shares with DGM 'Series B' the presence of laterally expanded neural spines and stout prespinal lamina. Additionally, A. mezzalirai shares with DGM 'Series' C (other titanosaur from Peiropolis) the presence of short neural spines.

Until recently, the rhynchonelliform (articulated) brachiopod fauna from the Brazilian continental shelf (western South Atlantic) was represented only by the endemic species Bouchardia rosea (Mawe), reported from coastal waters of the states of São Paulo and Rio de Janeiro. The present study, based on samples from coastal (<30 m), shelf, and continental slope waters (99-485 m), documents the South Atlantic brachiopod fauna and shows that this fauna is more widespread, diverse, and cosmopolitan than previously thought. Based on a total of 16,177 specimens, the following brachiopods have been identified: Bouchardia rosea (Family Bouchardiidae), Platidia anomioides (Family Platidiidae), Argyrotheca cf. cuneata (Family Megathyrididae), and Terebratulina sp. (Family Cancellothyrididae). In coastal settings, the fauna is overwhelmingly dominated by Bouchardia rosea. Rare juvenile (<2 mm) specimens of Argyrotheca cf. cuneata were also found at two shallow-water sites. In shelf settings (100-200 m), the fauna is more diverse and includes Bouchardia rosea, Terebratulina sp., Argyrotheca cf. cuneata, and Platidia anomioides. Notably, Bouchardia rosea was found in waters as deep as 485 m, extending the known bathymetric range of this genus. Also, the record of this brachiopod in waters of the state of Parana is the southernmost known occurrence of this species. The genera Platidia and Terebratulina are documented here for the first time for the western South Atlantic. The Brazilian brachiopod fauna shares similarities with those from the Atlantic and Indian shelves of southern Africa, and from the Antarctic, Caribbean and Mediterranean waters. The present-day brachiopods of the western South Atlantic are much more cosmopolitan than previously thought and their Cenozoic palaeobiogeographic history has to be reconsidered from that perspective.

Taphonomic analysis of pelecypod concentration in the part of the Teresina Formation (Passa Dois Group), Tiaraju region, State of Rio Grande do Sul, indicates its origins as due to high energy events (storms). The fauna include shallow-burrowing suspensivorous species, associated with this byssate semi-infauna species. Several taphonomic characteristics indicate that the fossiliferous assemblage was subject to little selective processes during transportation. These are: predominance of disarticulated valves (although articulated valves are frequent) and perpendicular, oblique, concordant and nested arrangement of bioclasts in the sedimentary matrix. Absence of fragmentation, bioerosion and incrustation of the bioclasts, suggest fast burial of shells due to high sedimentation rate events. Diagenetic features, indicate that the fossils were later submitted to refossilization and mixing with other non-coeval bioclasts, resulting in some degree of time-averaging.

During a recent inspection in the Paleontological Collection of the Institute of Geosciences, University of São Paulo, we have identifi ed some specimens of undescribed mollusk bivalves. These called our attention for the following reasons: a) all specimens are internal molds of conjugated and closed articulated valves, some of them presenting fragments of silicifi ed shells; b) all internal molds have similar general shape and internal characters, representing specimens of the same taxon; c) the internal molds and silicifi ed valves are well preserved, including fragile structures, which are hardly preserved, such as the internal mold of the external ligament and muscle scars; d) and equally important, according to the labels of all specimens, they were collected from rocks of the Passa Dois Group (Permian), Serrinha Member of the Rio do Rasto Formation. Although who collected the shells and the precise geographic location of the specimens are still unknown, the detailed study of these fossils brings us to the conclusion that they are morphologically distinct from any heretofore published genus of the endemic fauna of bivalves from Passa Dois Group. Based in its general shape, hinge structure and muscles scars, the new form can be classifi ed under the Family Megadesmidae Vokes, 1967, the most diverse group of Permian bivalves of the Paraná Basin. The specimens are referred as Beurlenella elongatella new gen. and sp. The shell shape and taphonomy indicate that this bivalve was a shallow, rapid, active burrower, suspension feeder, probably preserved in situ, in event deposits.

Taphonomy of the pygocephalomorpha (Crustacea, Peracarida, Malacostraca), Permian, Paraná Basin, Brazil, and its paleoenvironmental meaning. Crustaceans (Pygocephalomorpha, Peracarida) are the main fossil invertebrates recorded in the Early Permian Assistência Formation, Irati Subgroup, State of São Paulo, Paraná Basin. For this study, samples taken from the base of the Ipeúna Member, Bairrinho Bed, State of São Paulo, were analyzed and complemented by fossils from the Irati Formation, State of Rio Grande do Sul. The taphonomic spectrum of the pygocephalomorphs includes three main preservational modes: Type 1. Complete pygocephalomorphs (with outstretched or flexed abdomen), which are associated to cream-colored mudstones and more commonly to black shales. In rare cases, molds of soft parts are preserved. They suffered rapid burial (hours to days) by mud blankets associated to storm events in anoxic bottoms, below storm wave base with minimum bottom disruption, followed by low rates of background sedimentation; Type 2. Partly articulated (carapace and abdomen, with or without caudal fan and without appendages) pygocephalomorphs, with extended or flexed abdomen, which are present in cream-colored pelites, associated with hummocky cross-stratifications, intercalated with black shales. These may represent individuals or remains lying in the sediment-water interface preserved by rapid burial associated to episodic sedimentation events; Type 3. Disarticulated pygocephalomorphs, with isolated carapaces, abdomen, or abdominal segments. This is the predominant preservational mode in our samples. The skeletal remains can be found isolated or in dense, bioclast-supported concentrations (micro-coquines), representing proximal to distal tempestites. Finally, the extreme preservational quality seen in crustaceans of the Type 1 recorded in black shales, occasionally with molds of soft parts, indicates that the host rocks may represent Konservat-Lagerstätten deposits, as already suggested to coeval occurrences of the Irati Formation in Uruguay. © 2013 by the Sociedade Brasileira de Paleontologia.
