In this report we present and discuss an unpublished letter written by Santiago Ramón y Cajal in October 1904 in relation to his possible nomination for the Nobel Prize for Physiology and Medicine.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

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

The change in cattle size during the late Iron Age and the Early Roman period is a widely known phenomenon. However, hardly any information is available about this change and its causes in the north-east of the Iberian Peninsula. In order to shed more light on this issue, variations of cattle size and shape through the analysis of Bos taurus remains from ten archaeological sites located in the north-east Iberia and occupied from the middle fifth century bc to the third century ad are examined in this paper. Osteometric postcranial and teeth analyses show a clear change in cattle size and shape during the Romanization period at newly founded sites. This change is documented at all the sites from the Early Roman period. Genetically, authenticated results from a short fragment of the mitochondrial d-loop were obtained from 6 cattle metacarpals out of 33 tested. They affiliate to the main European taurine haplogroup T/T3. The integration of the available data including the archaeological background suggests that the presence of these morphologically different cattle, introduced during the Romanization period, was more pronounced at sites interpreted as villas and trading posts, rather than at cities during the Early Roman period.  相似文献

This article aims at illustrating the historical circumstances that led Julius Bernstein in 1902 to formulate a membrane theory on resting current in muscle and nerve fibers. It was a truly paradigm shift in research into bioelectrical phenomena, if qualified by the observation that, besides Bernstein, many other electrophysiologists between 1890 and 1902 borrowed ideas from the recent ionistic approach in the physical-chemistry domain. But Bernstein's subjective perception of that paradigm shift was that it constituted a mere reinterpretation of the so-called preexistence theory advanced by his teacher Emil du Bois-Reymond in the first half of the nineteenth century.  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

Abstract

This paper presents ethnographic, historic and archaeological data from the western Mediterranean in order to explore the variability of storage methods and the various strategies that may have existed in the past in this region. The paper includes ethnographic information on traditional storage methods collected in farming communities in northern Morocco (Rif area). We record the use of plant fibres such as canes (Arundo donax), dwarf palm (Chamaerops humilis), esparto grass (Stipa tenacissima) and dis (Ampelodesmos mauritanica) to make containers. Recipients made of cow dung and unfired clay, as well as underground silos, have been also used in this region to store food. In addition, we explore historical and ethnohistorical data on the use of large storage structures, including the study of communal granaries, a particular type of granary located at inaccessible places, such as cliff faces or mountain tops, or within fortified buildings, from which harvests can be easily protected and defended. We also examine the archaeological evidence of storage strategies in the Iberian Peninsula during prehistoric times. The paper informs of the large variety of systems and materials used, the functioning of storage structures, and more generally, provides a framework for reflecting on the enormous diversity of solutions that could have existed in the past and that may have left little or none archeological traces.  相似文献

Focusing on children's experience-driven cosmologies revealed through interviews and survey responses, this article seeks to analyse and interpret the way children explain their migration from the USA to Mexico within the context of increases in both voluntary and forced return migration of Mexicans since 2005. It draws from representative samples of students (aged 9–16) enrolled in both public and private schools in several Mexican states, which are complemented by data drawn from in-depth interviews that complicate the sociological typologies about migration, motives for migration, and returnees. The goals of this article are as follows: (a) to illuminate and value children's own narratives about their migration experiences and (b) to discuss the contribution of diverse and apparently contradictory micro-, meso-, and macro-level approaches in studying migrant children.  相似文献
