The Encounter between the West and the Arab World in the Age of Nahdah (Renaissance). The Translation Movement in the Arab Literary Reviews
No full textIn quest'articolo si riflette sul ruolo giocato dalla riviste letterarie arabe nella diffusione della conoscenza della cultura occidentale. Il movimento di traduzione avviato durante la Nahda (la Rinascita) in Egitto e nella Grande Siria condusse a cambiamenti sostanziali dei canoni estetici, ma suscitò anche un movimento di forte opposizione da parte dei conservatori
Native ungulates (Litopterna and Notoungulata: Mammalia) from the “Mesopotamiense” (Late Miocene) of Entre Ríos province, Argentina
No full textEl extenso aislamiento temporal y geográfico que mantuvo incomunicada a América del Sur durante gran parte del Cenozoico promovió el desarrollo de una fauna terrestre exclusiva de esta región. Dentro de esta fauna, se incluye a los “ungulados nativos sudamericanos” que tuvieron una amplia distribución en Argentina. Durante el Mioceno Tardío, estos ungulados se encuentran representados por los órdenes Litopterna y Notoungulata. En la provincia de Entre Ríos, procedentes del “Mesopotamiense” o “Conglomerado osífero”, base de la Formación Ituzaingó, se encuentran dos familias de litopternos, Proterotheriidae y Macraucheniidae, y dos de notoungulados, Toxodontidae e Interatheriidae. El estudio de estos grupos ha sido abordado por diferentes autores desde fines del siglo XIX hasta la actualidad. El objetivo de este capítulo es resumir los principales antecedentes sobre los taxones entrerrianos y presentar el estado actual del conocimiento de la historia biogeográfica de esta fauna particular sudamericana.The extensive temporal and geographical isolation of South America during most of the Cenozoic allowed the development of an exclusive terrestrial fauna in this region. Within this fauna are the so-called South American native ungulates, which are widely spread in Argentina. During the late Miocene, these ungulates were represented by the orders Litopterna and Notoungulata. In Entre Ríos Province, two litoptern (Proterotheriidae and Macraucheniidae) and two notoungulate families (Toxodontiidae and Interatheriidae) are recorded from the “Mesopotamiense” or “Conglomerado osífero”, base of the Ituzaingó Formation. The study of these groups has been addressed by different authors since the end of the XIX century. The aim of this chapter is to summarize the main information on the Entre Ríos taxa and to show the current state of knowledge on the biogeographic history of this South American particular fauna.Fil: Schmidt, Gabriela Ines.

Estimativa do número de pessoas com diabetes no Brasil em 2006 : projeções de 1986-1988 a partir de mudanças demográficas e nutricionais
No full textA prevalência de diabetes na população brasileira é freqüentemente descrita a partir de dados do Estudo Multicêntrico de Prevalência de Diabetes Mellitus (EMPDM), realizado entre 1986 e 1988 em 9 capitais brasileiras. O objetivo deste estudo é projetar esses achados para o ano de 2006, considerando as mudanças demográficas e nutricionais da população no período. Foram estimadas prevalência de diabetes específicas para categorias de sexo, idade e IMC no EMPDM, levando em conta o desenho amostral do estudo, em que o teste diagnóstico de diabetes e as medidas antropométricas foram realizadas apenas em sub-amostras. A estrutura demográfica da população brasileira foi obtida do IBGE para 1989, 2003 e 2006. Dados de obesidade e sobrepeso da população brasileira foram estimados por dois estudos nacionais, a Pesquisa Nacional de Saúde Nutricional (PNSN, 1989) e Pesquisa de Orçamento Familiar (POF, 2003). A prevalência de diabetes projetada para a população adulta brasileira em 1989 foi de 6,9%, chegando a um total de 3,3 milhões de indivíduos com diabetes. Em 2006, levando em conta mudanças demográficas e nutricionais, a prevalência estimada é de 7,3%, com um total estimado de 5,8 milhões de pessoas com diabetes. Indivíduos com excesso de peso (IMC > 25 kg/m2) representam 59% do total de indivíduos com diabetes em 1989 e aproximadamente 66%, em 2003 e 2006, esse aumento sendo mais acentuado entre os homens. Não existiu uma diferença importante entre as projeções realizadas com e sem as mudanças nutricionais
Milk molars or extra premolars in Mesotheriinae (Mesotheriidae, Notoungulata): New insights into an old controversy
No full textA recently recovered specimen of Mesotheriinae (Mesotheriidae, Notoungulata) from the late Miocene-early Pliocene of La Rioja Province (Argentina), CRILAR Pv 433, corresponds to an individual with three upper premolars, which appears to be an "anomaly" among mesotheriines. The detailed study of this specimen, however, brings up an old controversy on the interpretation of different mesotheriine specimens with three upper or two lower premolars. After being described as different taxa, these were later considered to be juvenile representatives of other known species. The three upper or two lower teeth were interpreted as the milk molars DP2-4 and dp3-4, respectively, which would be replaced in adult life just for two upper (P3-4) and one lower (p4) permanent premolars. The new material leads us to set up a different interpretation. In our opinion, all these specimens actually preserve the permanent dentition, corresponding to different ontogenetic stages of more or less young individuals. This consideration implies the necessity of a deep systematic revision of the whole subfamily keeping in mind this new point of view and the ontogenetic variation within a species. Therefore, the presence of P2/p3 is not enough to define a different taxon at this moment. Pending this taxonomic revision, the dental morphology of CRILAR Pv 433 resembles both Typotheriopsis (e.g., upper premolars with one labial sulcus) and Pseudotypotherium (e.g., P4 with lingual groove, wide median lobe of M3) as these two Late Miocene genera are currently characterized. Furthermore, P2/p3 could be expelled soon in the lifetime of individuals, and even the presence of P2/p3 could be a variable character within the same taxon; if so, this might reflect an evolutionary trend to the loss of a dental element within mesotheriines, but the revision of a large sample is necessary to support or reject these hypotheses.Fil: Cerdeño Serrano, Maria Esperanza.

Proterotheriidae (Mammalia, Litopterna) from the Cerro Azul Formation (late Miocene), La Pampa Province, Argentina
No full textRemains of Proterotheriidae (Litopterna) recovered from different localities in La Pampa Province, Argentina, are described. The fossiliferous levels in these localities correspond to the Cerro Azul Formation (late Miocene), where Chasicoan and Huayquerian faunal associations are known. The specimens of Proterotheriidae herein studied are assigned to Diplasiotherium pampa, Eoauchenia primitiva, cf. Brachytherium cuspidatum, Neobrachytherium sp. and Proterotheriidae indet. Although the holotype of D. pampa (left mandibular fragment with p3-m2) was defined in a previous paper, it is figured and fully described here, and its m3 is now known among the new collected specimens. Eoauchenia, Brachytherium and Neobrachytherium are registered in La Pampa Province for the first time, and the record of E. primitiva extends back to late Miocene its temporal distribution. Proterotheriids from the Cerro Azul Formation gather exclusive elements and others related to taxa represented in different Argentinean geological units corresponding to late Miocene-early Pliocene period.Fil: Schmidt, Gabriela Ines.

Systematic and biostratigraphic considerations on Thoatheriopsis Mendocensis Soria, 2001 (Litopterna, proterotheriidae)
No full textEl objetivo de esta contribución es analizar una colección de mamíferos fósiles procedentes de la Formación Salicas en el área de El Degolladito, provincia de La Rioja, Argentina. El material aquí reportado fue recolectado en dos sitios (sitio 1 y sitio 2). Los mamíferos registrados son: Macrochorobates Scillato-Yané, Chasicotatus Scillato-Yané, y Hoplophorini indet. (Xenarthra, Cingulata); Paedotherium minor Cabrera, cf Pseudotypotherium Ameghino (Notoungulata, Typotheria); Neobrachytherium Soria (Litopterna, Lopholipterna); Orthomyctera Ameghino, cf. Cardiomys Ameghino, Lagostomus (Lagostomopsis) Kraglievich, y Octodontidae indet. (Rodentia, Caviomorpha). La asociación de mamíferos presentada, junto con otra registrada previamente, tiene varios taxones en común con asociaciones de mamíferos del área central de Argentina (i.e., provincia de La Pampa). Entre aquellas del Noroeste de la Argentina, su mayor afinidad se da con las del Miembro El Jarillal (Formación Chiquimil) y la Formación Andalhuala (ambas en la provincia de Catamarca). La Formación Salicas es considerada de edad Miocena tardía hasta que nuevos registros fósiles y dataciones radioisotópicas permitan una mejor calibración. La información provista por la biota fósil y la interpretación geológica sugieren que la Formación Salicas se depositó en planicies bajo condiciones climáticas cálidas y secas. Este ambiente estuvo probablemente dominado por pastizales y áreas forestadas cercanas a ríos y lagunas.This study analyzes a collection of fossil mammals from the Salicas Formation in the El Degolladito area, La Rioja Province, Argentina. The materials reported herein were recovered from two sites (site 1 and site 2) and are: Macrochorobates Scillato-Yané, Chasicotatus Scillato-Yané, and Hoplophorini indet. (Xenarthra, Cingulata); Paedotherium minor Cabrera, cf Pseudotypotherium Ameghino (Notoungulata, Typotheria); Neobrachytherium Soria (Litopterna, Lopholipterna); Orthomyctera Ameghino, cf. Cardiomys Ameghino, Lagostomus (Lagostomopsis) Kraglievich, and Octodontidae indet. (Rodentia, Caviomorpha). This new mammalian assemblage, together with one previously recorded, has several taxa in common with mammalian associations from Central Argentina (i.e., La Pampa Province). Among those coming from Northwestern Argentina, the major affinity is with the El Jarillal Member (Chiquimil Formation) and then the Andalhuala Formation (both in Catamarca Province). The Salicas Formation fauna is considered as latest Miocene in age until new fossil discoveries and radioisotopic dates allow a better calibration. The fossil biota and geological data suggests that the Salicas Formation was deposited in flatlands, under warm and dry conditions. This environment was probably dominated by open grasslands, with forested areas near rivers and lagoons.Fil: Villafañe, Amalia Leonor. Museo Paleontológico Egidio Feruglio; Argentina.

UDC in Czechia
No full textPaper submission to this archive is arranged with the author by the editor of the proceedings. For further information contact the editor Maria Ines Cordeiro or Aida Slavic ([email protected])UDC is widely used in all types of libraries in the Czech Republic (Czechia). The classification plays an important role in the National Library as well as the entire library information network. It is central to the subject authority file of the National Library of the Czech Republic (NL CR) and its bibliographic services. The author explains the importance and potential of UDC use online especially in a multilingual context and illustrates this with examples from the national union catalogue, the Czech Uniform Information Gateway (UIG), the Multilingual Subject Access to Library Catalogues (MSAC) system and the Multilingual Content Aggregation System (M-CAST) projects. The advantages of using UDC in improving precision and recall are explained using the M-CASt system
Video Game, Author and Lemming: The Knowledge-Building Process
No full textMany studies show that video games require attentive and interpretive capacity to generate complex cognitive skills in the gamer and they can be transferred to other contexts, such as school. In this paper, the authors do not aim to investigate the contents of the player’s thinking, but rather his/her way of thinking. In this scenario the teacher becomes a worlds’ maker, who provides his/her students with the tools allowing them to partake in the co-building of multi-tiered worlds, which requires not only the ability to get access to intangible information but also a skillful management of media interfaces. In this way, the click of the mouse becomes the action par excellence that allows each individual to contribute synergistically to the realization of the digital habitats. The ultimate goal is to search, in the learning processes activated by the video games in both the authors and the lemming, those features that make the learner a self-knowledge builder. Such “socio-cultural grammar” influences the writing and interpretation of messages, turning every individual into an author, who’s often unaware of the “scriptwriting culture” that inhabits all the possible media worlds
