Sea-level changes and its impact on coastal archaeological monuments: seven pagodas of Mahabalipuram, a case study

The name `Seven Pagodas' has served as a nickname for the south Indian port of Mahabalipuram since the early European explorers used it as landmark for navigation as they could see summits of seven temples from the sea. There are many theories concerning the name Seven Pagodas. The present study has compared coastline and adjacent seven monuments illustrated in a 17th century Portolan Chart (maritime map) with recent remote sensing data. This analysis throws new light on the name ``Seven Pagodas'' for the city. This study has used DEM of the site to simulate the coastline which is similar to the one depicted in the old portolan chart. Through this, the then sea level and corresponding flooding extent according to topography of the area and their effect on monuments could be analyzed. Most importantly this work has in the process identified possibly the seven monuments that constituted the name Seven Pagodas and this provides an alternative explanation to one of the mysteries of history. This work has demonstrated unique method of studying coastal archaeological sites. As large numbers of heritage sites around the world are on coastlines, this methodology has potential to be very useful for coastal heritage preservation and management.

The Ahupua'a concept: relearning coastal resource management from ancient Hawaiians

Isolated in the middle of the Pacific Ocean, Hawaii was one of the last areas to be reached by "western" explorers; as a consequence, some ancient traditions were preserved in Hawaii well into the 19th and 20th centuries, providing an opportunity to learn from a surviving indigenous culture. An account is given of the division of the islands into various units and their exploitation. The smallest major divisions were the "ahupua'as," which spread out at the base along the shore and were self-sufficient units. In this way the ancient Hawaiians recognized the relationship between the land and sea, rainfall and vegetation, nutrients and runoff and preserved the integrity of the delicately balanced ecosystem of which they were a part and upon which they relied for their every need. Modern parallels to this ancient system are broken and irregular; the reorganization of the "ahupua'a" system marked the beginning of the decline of Hawaiian ecosystems. Although steps are being taken to remedy the present situation, Hawaii now ranks among the highest in the nation for its levels of pollution, endangered species and disappearing habitats. More and more, the model for improved management is being sought in the revival of ancient traditions.

Chartered Trawling on the Brazilian Slope

Commercial trawling on the Atlantic slope areas off Brazil intensified in the late 1990’s owing to the expansion of coastal trawling areas and the operations of a chartered foreign fleet. Between 2000 and 2003, 59 fishing trips conducted by 10 chartered trawlers were intensely monitored by observers and satellite vessel monitoring systems, totaling 9,069 tows and 30,085.2 trawling hours. Fishing operations occurred in northern, northeastern, southeastern, and southern sectors of the Brazilian coast in 60–1,173 m depths. Total retained and processed catch were 8,074.6 t and 6,479.8 t, respectively. Argentine hake, Merluccius hubbsi; and Argentine shortfin squid, Illex argentinus, were the primary species taken contributing to 41.1% and 28.6% of the overall catch, respectively. The silver John dory, Zenopsis conchifera; monkfish, Lophius gastrophysus; Brazilian codling, Urophycis mystacea; and the black grouper, Epinephelus nigritus, composed 23% of total processed catch, and the remaining 7.2% was composed of deep-sea shrimps (family Aristeidae) and other teleosts and elasmobranches. The occupation of slope areas included an early exploratory phase, followed by directed phases of the upper slope (300–500 m), aiming principally at the Argentine hake, and the lower slope (>700 m), targeting valuable concentrations of deep-sea aristeid shrimps. The role of chartering for slope trawling development was critically addressed. We conclude that chartered vessels were efficient explorers and were particularly important in areas not available to the technologically limited national fleet. Because the charters were market-oriented and had elevated profit demands, however, those vessels quickly turned from exploration to exploitation and competed with national trawlers in shallower areas and produced significant impacts on Brazil’s modest deep-sea resources.

Fishery resources: their exploitation, management and conservation in Africa

The beginning of the 20th century saw the discovery of Africa's vast natural resources. Not only did explorers "discover" lakes, rivers, forests and mountains but scientists and naturalists also "discovered what at that time were called new species of plants, fish and other animals. Thus scientific names were tagged to various species using the famed binomial nomenclature and immortalising the names of some of the people who first described those species. Africa of course abounds with thousands of different floral and faunal varieties and the early colonial scientists found the African environment lucrative fron the point of discovery of new species. This paper therefore attempts to descrihe the role science could only in the development and exploitation of one of Africa's renewable resources namely fisheries. This paper has attempted to expose the value of fish in human nutrition, provision of employment and uplifting of social and economic standards. The fishery resources of Africa are extensive and in the main not fully exploited. These resources like other natural resources are exhaustible although renewable. Efforts to exploit these resources must be encouraged but scientific planning and management of the resource is called for.

La traduction intersémiotique et l’hybridité dans la Nueva coronica y buen gobierno de Felipe Guamán Poma de Ayala : analyse des rapports de pouvoir ethniques

La fin du XVe siècle marque le début d’une nouvelle ère dans les Amériques. L’arrivée des explorateurs, des conquistadores et des colonisateurs espagnols au nouveau continent signe l’introduction des Amériques dans l’histoire. Dans les écrits rédigés durant les premières décennies de la colonisation, les Autochtones endossent majoritairement le rôle d’objet. À la suite de l’endoctrinement d’une partie de la population autochtone, ce rôle passif se transforme en rôle davantage actif alors que certains Autochtones décident de prendre la parole et la plume. Voilà ce que Felipe Guamán Poma de Ayala décide de faire par l’entremise de sa chronique Nueva coronica y buen gobierno, rédigé en 1615 et adressé au roi Philippe III d’Espagne. Ce mémoire étudie une sélection d’images de la chronique comme traductions culturelles intersémiotiques de la société coloniale dans la mesure où elles traduisent le vécu colonial, y compris les rapports de pouvoir ethniques au sein de la hiérarchie sociale, à l’aide d’unités sémiotiques provenant de divers codes culturels (espagnol, catholique et andin). L’objectif de ce projet de recherche consiste à démontrer la façon dont l’hybridité du système sémiotique du texte cible expose la nature aliénante de la traduction ainsi que la relation antagonique qu’elle entretient avec l’idéologie coloniale officielle.

Diferença entre homens e mulheres na propensão em adotar produtos e serviços tecnológicos

The construct Technology Readiness (TR) and its instrument of measure Technology Readiness Index (TRI) defined by Parasuraman (2000), refer to people¿s propensity to adopt digital technological products and services. The TR can be viewed as an overall state of mind resulting from mental drivers and inhibitors related to optimism, innovativeness, discomfort and insecurity. These facets combine into a complex way for produce distinct groups of individuals (explorers, pioneers, skeptics, paranoids and laggards) with different traits of behaviors connected to the adoption of technological products and service. This study had as its objective to evaluate the applicability of the TRI in the Brazilian context, through the replication of the scale on a sample of 336 adults consumers (168 men and 168 women) resident in the state of the Rio de Janeiro, segmented by age groups, educational level and monthly family income. The results show that, in the sample analyzed, as culturally the technology is linked to values of a male society, men presented a higher propensity in adopting technological products and services than women. However, this hypothesis was not confirmed in the analysis segmented by age groups.

Uma América incógnita

Se os cronistas espanhóis inventaram paulatinamente o que viria a ser a América, como O' Gorman propôs, os cronistas portugueses da primeira metade do século XVI foram bem mais cautelosos na construção de uma identidade para os territórios do ultramar visitados por Colombo e por Cabral. Esses cronistas quinhentistas, com os olhos na Ásia, só tardiamente deixaram de pensar esse quase um outro mundo como lugar de passagem para pensá-lo como lugar de parada. Embora distanciando-se do tom de espanto que marca cartas e relatos utilizados como fontes e revelando uma preocupação em atribuir um lugar específico para a viagem de Cabral na construção da história portuguesa, as peripécias dos navegadores sobressaem às peculiaridades das terras e gentes que viriam futuramente a merecer dos seus congêneres uma atenção especial. Neste ensaio, o alvo visado é o lugar, na cronística portuguesa quinhentista, conferido a esses territórios de pouco prestígio, melhor, o lugar que lhe é concedido na memória portuguesa desses primeiros tempos.

Preservação e patrimônio no instituto histórico e geográfico de São Paulo (1894-1937)

O Instituto Histórico e Geográfico de São Paulo, inaugurado no ano de 1894, foi um dos mais importantes espaços de formulação ideológica das elites intelectuais paulistas, na virada do século XIX. Ao longo da primeira república, esses associados produziram um vasto e eclético conjunto de artigos, unindo, de forma bastante singular, beletrismo e erudição com os paradigmas científicos próprios de sua época. Além disso, os sócios do IHGSP, localizados em um período anterior à consolidação dos espaços acadêmicos, também discutiram aspectos da preservação do patrimônio local e regional, inserindo-os em uma lógica própria de valorização da história e da civilização bandeirante, como um modelo de ação e atuação a ser admirado e seguido por todo o país.

Recent benthic foraminiferal distribution and related environmental factors in Ezcurra Inlet, King George Island, Antarctica

This investigation attempts to determine which environmental parameters of the bottom water and sediment control recent foraminifera fauna at Ezcurra Inlet (King George Island, Antarctica), using data collected during four summers (2002/03, 2003/04, 2004/05 and 2006/07). The study revealed that Ezcurra Inlet contain typical Antarctic foraminifera fauna with three distinct assemblages and few differences in environmental parameters. The species Bolivina pseudopunctata, Fursenkoina fusiformis, Portatrochammina antarctica, and Adercotryma glomerata were abundant in the samples. An elevated abundance, richness and diversity were common at the entrance of the inlet at depths greater than 55 m, where the inlet was characterized by low temperatures and muddy sand. In the inner part of the inlet (depth 30-55 m), richness and diversity were low and the most significant species were Cassidulinoides parkerianus, C. porrectus, and Psammosphaera fusca. Shallow waters showed low values of richness and abundance and high temperatures coupled with coarser sediment. In areas with high suspended matter concentrations and pH values associated with low salinity the most representative species were Hippocrepinella hirudinea and Hemisphaerammina bradyi.

Mapping the biosphere: exploring species to understand the origin, organization and sustainability of biodiversity

The time is ripe for a comprehensive mission to explore and document Earth's species. This calls for a campaign to educate and inspire the next generation of professional and citizen species explorers, investments in cyber-infrastructure and collections to meet the unique needs of the producers and consumers of taxonomic information, and the formation and coordination of a multi-institutional, international, transdisciplinary community of researchers, scholars and engineers with the shared objective of creating a comprehensive inventory of species and detailed map of the biosphere. We conclude that an ambitious goal to describe 10 million species in less than 50 years is attainable based on the strength of 250 years of progress, worldwide collections, existing experts, technological innovation and collaborative teamwork. Existing digitization projects are overcoming obstacles of the past, facilitating collaboration and mobilizing literature, data, images and specimens through cyber technologies. Charting the biosphere is enormously complex, yet necessary expertise can be found through partnerships with engineers, information scientists, sociologists, ecologists, climate scientists, conservation biologists, industrial project managers and taxon specialists, from agrostologists to zoophytologists. Benefits to society of the proposed mission would be profound, immediate and enduring, from detection of early responses of flora and fauna to climate change to opening access to evolutionary designs for solutions to countless practical problems. The impacts on the biodiversity, environmental and evolutionary sciences would be transformative, from ecosystem models calibrated in detail to comprehensive understanding of the origin and evolution of life over its 3.8 billion year history. The resultant cyber-enabled taxonomy, or cybertaxonomy, would open access to biodiversity data to developing nations, assure access to reliable data about species, and change how scientists and citizens alike access, use and think about biological diversity information.
