Papillomaviruses (PVs) are widespread pathogens. However, the extent of PV infections in bats remains largely unknown. This work represents the first comprehensive study of PVs in Iberian bats. We identified four novel PVs in the mucosa of free-ranging Eptesicus serotinus (EserPV1, EserPV2, and EserPV3) and Rhinolophus ferrumequinum (RferPV1) individuals and analyzed their phylogenetic relationships within the viral family. We further assessed their prevalence in different populations of E. serotinus and its close relative E. isabellinus. Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. Second, the ability of EserPV2 and EserPV3 to infect two different bat species (E. serotinus and E. isabellinus) argues against strict host specificity. Finally, the description of a second noncoding region in the RferPV1 genome reinforces the view of an increased susceptibility to recombination in the E2-L2 genomic region. These findings prompt the question of whether the prevailing paradigms regarding PVs evolution should be reconsidered.

[EN] In this article we explain the etymology of the surnames of Basque origin that some presidents of Latin American countries have or have had in the past. These family names were created in the language called Euskara, in the Basque Country (Europe), and then, when some of the people who bore them emigrated to America, they brought their surnames with them. Most of the family names studied here are either oiconymic or toponymic, but it must be kept in mind that the oiconymic ones are, very often, based on house-nicknames, that is, they are anthroponymic in the first place. As far as possible, we have related the surname, when its origin is oiconymic or toponymic, to its source, i.e. to the house or place where it was created.

Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To explore the above two bias problems with f ield-collected European pilchard (Sardina pilchardus, known regionally as the Iberian sardine), a method was developed in which the time elapsed from spawning (POF age) was estimated from the size of POFs (i.e., from the cross-sectional area in histological sections). The potential effect of the preservative type and embedding material on POF size and the effect of ambient water temperature on POF resorption rate are taken into account with this method. A highly significant loglinear relationship was found between POF area and age; POF area shrank by approximately 50% per day. POFs were also shown to shrink faster at higher temperatures (approximately 3% per degree), but this temperature effect is unlikely to be an important source of bias in the assignment of females to daily spawning classes. The embedding material was also shown to influence the size of POFs, the latter being significantly larger in resin than in paraffin sections. In conclusion, the size of POFs provides an indirect, reliable estimation of the time elapsed from spawning and may thus be used to test both the validity of POF staging criteria for identifying daily classes of spawners and the effect of other factors (such as temperature and laboratory processing) in applications of the DEPM to S. pilchardus and other fish species.

A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH II approach implemented as a new, Windows-based software is then shown to allow construction of a stratified world model accoutinng for global catches, production of and predation on fishes, and thus improved estimates of global potentials. A newly initiated, cooperative project is described through which the foundation for such a global model could be constructed, based on a stratified database with more than 100 trophic models. Collaborators are invited to join in this, and will be assisted in constructing models covering their areas of interest.

Emergent properties of global political culture were examined using data from the World History Survey (WHS) involving 6,902 university students in 37 countries evaluating 40 figures from world history. Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.

O presente trabalho busca examinar, em perspectiva histórica, aspectos sociopolíticos e jurídicos relacionados à formação da Administração Pública no Brasil e às suas características, notadamente no que concerne ao processo de legitimação do exercício do poder pelo aparelho burocrático e ao seu potencial controle pelos cidadãos. Argumenta-se que, se por um lado tais características revelam a resistência de um modelo associado ao legado ibérico, de outro evidenciam uma peculiar e progressiva abertura ao controle democrático, especialmente após a redemocratização e a promulgação da Constituição Federal de 1988. Adotando o exercício do poder administrativo discricionário como categoria de análise, os aspectos inerentes ao processo de transformação daquele modelo são examinadas a partir de quatro eixos, a saber: a singular tensão entre Iberismo e Americanismo no Brasil; a renovação teórica acerca da democracia representativa e das perspectivas sobre o controle democrático; o pós-positivismo e sua potencial conexão com uma concepção responsiva do direito e, finalmente, a queda de velhos paradigmas de legitimação do exercício do poder discricionário estatal, em âmbito mundial, a partir dos anos 1980, o que teria dado ensejo ao crescimento e fortalecimento de um escrutínio pragmático e consequencialista das decisões discricionárias da administração pública também no Brasil.

The differences between fishes in their size, behavior and food make them more or less vulnerable to fishing pressure. Large predators, long-lived fish, most trawl species and pelagic schooling fishes will possibly become extinct, to be replaced by small nonschooling unpalatable species such as lanternfish.

A presente tese está calcada na análise da obra de Ariano Suassuna, o Romance dA Pedra do Reino e o príncipe do sangue do vai-e-volta, considerado pelo autor como a sua obra maior e, a princípio, o primeiro volume da trilogia A maravilhosa desaventura de Quaderna, o decifrador, e no primeiro volume da segunda parte da trilogia, O rei degolado ao Sol da Onça Caetana. O trabalho consiste, fundamentalmente, em examinar o diálogo estabelecido entre a obra de Suassuna com textos representativos da tradição literária ocidental, mais propriamente com os que remontam ao medievo. Para isso, fez-se um recorte nas relações que o romance trava com a matéria cavaleiresca, principalmente com a Demanda do Santo Graal, na sua estrutura e no desenho psicológico e moral dos personagens, notadamente de Sinésio, que encarna o mito do herói prometido, cujos paradigmas se assentam na figura lendária do Rei Artur, além de Galaaz, e na histórica de D. Sebastião, o rei desaparecido de Portugal. Sabe-se que esses reis e heróis míticos, considerados salvadores, uma vez que retornariam para restituir ao povo a dignidade e a liberdade perdidas, povoaram o imaginário ibérico e chegaram ao Brasil trazidos pelos colonizadores europeus. Dessa forma, a cultura popular do Nordeste brasileiro é povoada de histórias e lendas eternizadas e recriadas no folclore da região e na literatura de Cordel. Mas, ao lado do messianismo, outro aspecto faz-se notório nos personagens de Suassuna: a crueldade. E este tema, bem como o nome do personagem D. Pedro Dinis Quaderna, remete-nos para a história de alguns reis ibéricos da Idade Média: Pedro de Portugal e Pedro de Castela, que serão revisitados à luz da Crônica de D. Pedro de Fernão Lopes, no intuito de observar-se o diálogo com esta estabelecido por Suassuna, direta ou indiretamente

Sea cucumbers (Holothuridae and Stichopodidae) have been harvested commercially for at least 1,000 years. The world fisheries for sea cucumbers, however, are not well documented and in general are poorly managed. Depending upon the species exploited, there are two processing procedures for the sea cucumber product. Some species are eaten raw, while most commercial species are processed into a dry product called beche-de-mer or trepang. This dry product is exported to a central market such as Hong Kong and then re-exported to the consumers. In this review, recent statistics on the world sea cucumber fisheries, collected from different services, are detailed for each major fishing area. Case studies for each fishing area are also presented. Recent major changes in the Indo-Pacific fishery include the participation of new producer countries, the shift in the species being exploited, and an increase in the Chinese market. The expansion of the largely monospecific temperate North Pacific fisheries is also described. Statistics from Hong Kong, Singapore, Taiwan, and the Food and Agriculture Organization provide valuable information on the producer and importer countries. Particular attention is paid to the reciprocal trade of beche-de-mer between Hong Kong and Singapore. An evaluation of the world sea cucumber landings and beche-de-mer production is presented. Recent developments include an expansion of the Hong Kong market due to increased demand by China, the importance of Indonesia as a major world producer, and an increase in the fisheries of Tropical Pacific nations. This increase is best documented for New Caledonia and Fiji. Ways to improve the access and the reliability of the statistics for the sea cucumber fishery are discussed, as is the potential for management of artisanal fisheries.

World farmed salmon production reached 145,000 metric tons (t) in 1988 and an estimated 217,000 t in 1989. The latter figure is comparable to the U. S. annual salmon catch (about 250,000 t) and is approaching one-third the size of the world wild salmon catch (about 700,000 t). The rapid expansion of farmed salmon supplies in the late 1980's has led to sharp price decreases. Lower prices have forced some farmers out of business, but at the same time, a large number of farmers first began harvesting salmon on a commercial scale as the 1980's ended. Farmed salmon production could exceed 270,000 t in 1990.

This special section of the Marine Fisheries Review contains the edited proceedings of a symposium held on 16 September 1987 at the annual meetings of the American Fisheries Society in Winston-Salem, N.C. The symposium was sponsored by the National Marine Fisheries Service of the National Oceanic and Atmospheric Administration, and the International Institute of Fisheries Economics and Trade. The aim of this session was to provide an overview of several international trade issues that affect the development of fisheries economic policy. Thus, the general areas of discussion included: The role of fisheries in the U.S. balance of trade, current negotiations on fisheries trade and tariffs, and U.S. and foreign economic trade strategies and policies.
