In this article, we present the results of the 2011 field season at the Iron Age burial site of Nandá, on the Island of Corisco, located between Equatorial Guinea and Gabon. The excavations followed a survey conducted in 2009, which evinced the extraordinary interest of the site and suggested its funerary nature. The excavations documented three levels of occupation belonging to two different phases, which are known in the region as Oveng (ad 1–600) and Group II (ad 600–1100). The first phase was characterized by secondary burials with rich metallic offerings, which were sealed by a settlement at the end of the period; the second phase witnessed the establishment of a large burial site with primary interments. Similar burials are known from Cameroon and Gabon, but the number of features identified at Nandá and the funerary sequence are quite unique in the region. Here, the evidence will be interpreted in light of Jan Vansina’s theories, where he postulates a common political tradition in Equatorial Africa from which later developments stem.  相似文献

Brea, M., Zamuner, A.B., Matheos, S.D., Iglesias, A. & Zucol, A.F., December, 2008. Fossil wood of the Mimosoideae from the early Paleocene of Patagonia, Argentina. Alcheringa 32, 427–441. ISSN 0311-5518.

An anatomically preserved mature stem from the Salamanca Formation (early Paleocene) at Palacio de Los Loros, central Patagonia, Argentina, is described and assigned to Paracacioxylon frenguellii sp. nov. The material was preserved by siliceous permineralization and shows features of the secondary xylem typical of subfamily Mimosoideae. This species represents the oldest record of the genus and of the Leguminosae along the western border of Gondwana, and is the world's second oldest record of Leguminosae wood. The species is characterized by ring-porous to semi-ring-porous vessels that are solitary, in multiples of 2–4 and clustered, simple perforation plates, alternate and vestured inter-vessel pitting, homocellular 1–6 seriate rays, tyloses, crystals and diffuse apotracheal, vasicentric paratracheal and confluent axial parenchyma. Paracacioxylon frenguellii has anatomical similarities to Acacia Miller. The presence of Paracacioxylon frenguellii associated with pulvinate leaves suggests that the legumes might have been a component of mesothermal forests developed along the western margin of the Golfo San Jorge Basin during the early Paleocene.  相似文献

Cruise Passengers in a Homeport: A Market Analysis   总被引:1,自引:0,他引:1  
Abstract

The aim of this study is to examine cruise passengers' characteristics, preferences and their overall experience in a port of call. Based on 1,361 survey data collected from passengers in the port of call of Cartagena, during the third quarter of 2009, a three-step multivariate market segment analysis is employed. First, a correspondence analysis is run to reveal the underlying factors in the data; second, based on the correspondence analysis, a hierarchical cluster investigation is performed to segment the sample into homogeneous groups; third, a decision tree is computed to characterise each group. The cluster analysis identifies six distinct market segments differentiated by nationality, satisfaction, safety perception and expenditure. The findings imply several policy directions. In particular, institutions should enhance the perception of safety in Cartagena to guarantee repeated visits, an ad hoc marketing policy may encourage revisit by young South Americans, and managers should extend the inland visiting time that is likely to produce local multiplier effects.  相似文献

In this report we present and discuss an unpublished letter written by Santiago Ramón y Cajal in October 1904 in relation to his possible nomination for the Nobel Prize for Physiology and Medicine. This letter shows that Cajal was aware of his previous nominations for the Prize. He was convinced that these nominations had not been successful because neither anatomy nor histology were among the sciences included in the Nobel Statutes' definition of Physiology or Medicine. He gives a list of the merits he thought might be used for a new nomination, which included only works concluded during the previous five years.  相似文献

The aim of the article is to show that the Mutiozabal shipyard in Orio, Gipuzkoa, Spain, was using the tools and procedures of non‐graphic hull‐design methods into the latter 19th and early 20th centuries. These procedures allow a hull to be designed with a very simple set of tools: a template of the master‐frame and some simple graduated gauges or graminhos. The plan of a 65‐Burgos‐foot 1 (18.11 m) trading boat is used as the basis of the study. The nature of the templates and graminhos is shown in detail, as well as their use.  相似文献

The economic crisis that started in 2009 has negatively impacted in the Netherlands the available financial resources for urban development. Dutch municipalities struggle since then with falling local financial sources, especially since active public land policy, traditionally an important additional financial source, became not so profitable anymore. One supposed effect is the limited degree to which municipalities can nowadays finance public infrastructure that serves wider areas, thus more than one specific development site (i.e. ‘large’ public infrastructure). Until now, however, there are no data available that support this claim. In this paper, we explore this and the role that developer obligations can play as an alternative, compensating financial source. Developer obligations are in many countries a growing popular public value capturing instrument, but in the Netherlands, a relative new phenomenon. On the basis of surveys, interviews and policy analysis, we conclude that at least a quarter of Dutch municipalities use developer obligations to obtain financial sources for large infrastructure. This seems, however, so far not to compensate for the diminishing of other municipal financial sources. The paper ends with some speculation about the future evolvement of developer obligations in the Netherlands.  相似文献
