Underwater survey of ichthyofauna of eastern Atlantic seamounts: Gettysburg and Ormond (Gorringe Bank)

Gettysburg and Ormond are seamounts belonging to the Gorringe Bank, which is located on the Europen-African plate boundary. Given the importance of these oceanic features for understanding marine biodiversity patterns, two surveys were carried out in 1998 (Gettysburg) and 1999 (Ormond) using diving, photography and video for species identification and abundance evaluation. Of the 9 fish species found at Gettysburg and 11 at Ormond, 6 were common to both sites and these included the dominant species: the oceanic and commercially important, Seriola rivoliana, and the coastal, typically Atlantic-Mediterranean Coris julis and Anthias anthias. The strong representation of coastal, demersal and Atlantic-Mediterranean species in the Gorringe Bank region and the presence of Abudefduf luridus, an endemic Macaronesian species, at Gettysburg suggests that the upper part of these seamounts may have acted and still act as “stepping stones” for the dispersal of coastal species.info:eu-repo/semantics/publishedVersio

Using an Analytic Hierarchy Process Approach to Prioritize Public Policies Addressing Family Farming in Brazil

In Brazil, some see intensive, large-scale production of sugarcane-based ethanol, based on a model of capital and land concentration, as a threat to the survival of family farming. Family farmers are increasingly under pressure to sell or rent land to mills where sugarcane monoculture is expanding. In this context, the government is working to formulate or change public policies in order to support farmer livelihoods in sugarcane growing regions. The present study is based on research conducted in the municipality of Ipiranga de Goiás, Goiás State, Brazil. It employs the analytic hierarchy process (AHP) method, with participation of stakeholders at federal, state and municipal levels, to support public policy decision-making addressing family farming. The stakeholders prioritize environmental and economic benefits as the most important criteria requiring the attention of policy makers. Also, stakeholders agree that diversification of production is the most appropriate alternative for strengthening family farming. The AHP approach can be the starting point in the formulation of public policies. The approach helps ensure transparency, and it purposefully includes family farmer points of view. Policies derived from this process, therefore, may have a higher likelihood of being supported and accepted by farmers

Ichthyofauna assemblages from two unexplored Atlantic seamounts: Northwest Bank and João Valente Bank (Cape Verde archipelago)

Underwater censuses by divers were used to study the fish assemblages from two unexplored Atlantic seamounts in the Cape Verde archipelago. Fifty three species of 27 families were recorded: 27 in Northwest Bank and 46 in João Valente Bank. Northwest Bank had dense schools, while João Valente Bank had higher species richness and smaller schools. Both seamounts were dominated mainly by coastal species directly depending on seabed habitat (Demersal or benthopelagic). Of the 53 fish species recorded, 22.6% were of continental African origin, while 9.4% and 5.7% were endemic of the Cape Verde Islands and of the Macaronesia province, respectively. Most species (64.2%) had a very wide biogeographic distribution: cosmopolitan (22.6%), amphi-Atlantic (28.3%) and Atlantic-Mediterranean (13.2%). Northwest Bank and João Valente Bank may have a permanent fish community supported by various oceanographic-topographic interactions. João Valente Bank seems more diverse, which is probably associated with algae cover and with a larger area providing additional suitable and more varied habitats. The geographic proximity to the coast and the presence of oceanic and/or oceanodromous species suggests that the upper part of these seamounts may act both as attraction points and as “stepping-stones” for the dispersal of coastal species.info:eu-repo/semantics/publishedVersio

Analise semiotica de um ava (ambiente virtual de ensino aprendizagem) : características cts através da escada semotica de Stamper

Este artigo demonstra um estudo e aplicação da análise semiótica, para a avaliação de interfaces de ambientes virtuais de ensino-aprendizagem (AVA), de acordo com a escada semiótica de Stamper. Com base nas características CTS (Ciência,Tecnologia e Sociedade) encontrada nas camadas “degrais” da escada. Em específico, usamos a metodologia para qualidade de interfaces definida por Schimiguel, que instancia critérios de qualidade para cada uma das camadas da escada semiótica de Stamper. Com base nos resultados dessa investigação foi possível sugerir algumas recomendações nas seis camadas analisadas, sinalizando ainda para cada uma dessas recomendações um enfoque CTS, uma descrição que tem como propósito facilitar a implementação e otimização de AVAS

Lugares e gentes: as rela??es entre pessoas, paisagens e Arqueologia em Fel?cio dos Santos, Alto Vale do Ara?ua?, Minas Gerais ? (2010-2019)

Linha de pesquisa: Hist?ria, Cultura e Arqueologia.Este trabalho buscou estudar as inter-rela??es entre os moradores de Fel?cio dos Santos, Minas Gerais, e seus ambientes; entendendo como os lugares foram estabelecidos como paisagens ao longo dos anos. Sabe-se que a mem?ria das ocupa??es ind?genas no Vale do Jequitinhonha desapareceu quase por completo em fun??o dos processos de conquista e coloniza??o europeia, que resultou, por exemplo, na aus?ncia de dados sobre o primeiro contato entre europeus e nativos da regi?o. Portanto, buscamos abordar o processo de ocupa??es humanas no passado e quais suas implica??es e perman?ncias no presente, pois, ao longo do tempo os lugares foram transformados em paisagens de acordo com as vis?es de mundo e necessidades das pessoas que ?quela ?rea ocuparam. Foi preciso investigar como as pessoas compreendem e se identificam com o meio onde vivem; quais s?o as formas de relacionamento estabelecidas com os elementos constitutivos da paisagem regional e quais as a??es da sociedade civil e do poder p?blico em prol da salvaguarda dos bens culturais do Munic?pio. Para isso, foram retomadas discuss?es te?rico-bibliogr?ficas de ?reas interdisciplinares acerca das tem?ticas da pesquisa. Estudos anal?ticos foram conduzidos para a interpreta??o e a contextualiza??o de documentos hist?ricos, imagens fotogr?ficas, mapas cartogr?ficos. Os conte?dos dos question?rios e das entrevistas realizadas foram ent?o analisados. Esta pesquisa permite ?s partes interessadas ampliar os horizontes acerca das ocupa??es humanas no Vale do Ara?ua? para que as pol?ticas de gest?o e conserva??o dos patrim?nios culturais sejam efetivamente empregadas nessa regi?o. Considera-se, ent?o, que no din?mico processo de ocupa??o humana daquela regi?o os lugares se constitu?ram em paisagem ? medida que os humanos estabeleceram la?os identit?rios com os elementos ao entorno. ?, portanto, com o intuito de entender as m?ltiplas maneiras dos moradores de Fel?cio dos Santos se inter-relacionarem com o meio que se realizou esta pesquisa.Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Ci?ncias Humanas, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2020.This work aims to study the relationships between the inhabitants of the municipality of Fel?cio dos Santos, Minas Gerais state, and their environments, in order to understanding how the sites have become landscapes over time. It is known that the memory of indigenous occupations in the Jequitinhonha Valley disappeared almost entirely due to the processes of European conquest and colonization, which resulted, for example, in the absence of data on the first contact between Europeans and the natives of the region. Therefore, we addressed the process of human occupations in the past, as well as their implications and permanence in the present time. Over time, places have become landscapes according to the views of the world and the needs of people in that area. It was studied how people understand and identify with the site where they live; what are the forms of relationship established with the constituent elements of the regional landscape; and what are the actions of civil society and the public authorities in favor of safeguarding the cultural assets of the Municipality. For this, theoretical-bibliographic discussions from interdisciplinary areas were resumed on the research themes. Interpretation and contextualization of historical documents, photographic images, and cartographic maps were carried out. The contents of the questionnaires and interviews were then analyzed. This research allows interested stakeholders to broaden their knowledge about human occupations in the Ara?ua? Valley in order to the policies for the management and conservation of cultural heritage are effectively employed in this region. We also taken into the account that in the dynamic process of human occupation of that region, sites become landscape as humans established identity ties with the elements around them. It is, therefore, in order to understand the multiple ways in which Fel?cio dos Santos inhabitants interact with the environment in which this research was carried out
