Hispania and the Atlantic Route in Roman Times: new Approaches to Ports and Trade

This paper explores the role of Hispania in the Atlantic route in Roman times. We analyse the different Atlantic Iberian territories along this route, based on recent archaeological advances and discoveries related to trade as well as the shipping infrastructure. The aim is to explain the origin and evolution of a new maritime area that was completely integrated with the political and commercial structure of the Empire, with trade routes that followed the coastal areas of the Iberian Peninsula all the way to the Mediterranean.     

The Ubiquity of Rhetoric and Hermeneutic Philosophy

This essay examines how hermeneutic philosophy, particularly Gadamer's, recovers rhetoric, less as the art of speaking well than as a statement of a truth of the sensus communis, that which communicates veracious content through argumentation. This is the sense in which Gadamer acknowledges the ubiquity of rhetoric and hermeneutics as components of linguisticity (Sprachlichkeit). Conceived in the context of non-methodical wisdom and phronesis, Gadamer's rehabilitated rhetoric is concerned with pragmatics and ethics. Rhetoric is no longer viewed as a technique of verbal manipulation and becomes relevant for dialogic communication. Gadamer thus joins the Habermasian criticism of formalized reason that is detached from values. Both of them reject instrumental reason, because it has colonized communicational reason. However, since Gadamer's view of rhetoric has also been criticized by Habermas and Ricoeur their objections cannot be overlooked in a discussion of his hermeneutics. The essay concludes with a brief consideration of the implications of the debate on rhetoric, hermeneutics, and communication for the twenty-first century.     

Network Location and Policy‐Oriented Behavior: An Analysis of Two‐Mode Networks of Coauthored Documents Concerning Climate Change in the Great Lakes Region*,†

This study explores how a scientist's location in science‐based policy networks can affect her policy‐oriented behaviors. In particular, we hypothesize that those scientists who fill structural holes in their networks will be more likely than others to engage in policy‐oriented behaviors. The network data are defined by scientists' coauthorship on policy documents regarding climate change in the Great Lakes. We employ a two‐mode network analysis to identify clusters of scientists who coauthored similar documents, and relative to those clusters, we identify those who fill structural holes by bridging between clusters. We find that those scientists who bridged between clusters were more likely to engage in policy‐oriented behaviors of policy advocacy and advising than were others in the network. This is an example of a link between network location and policy‐oriented behavior indicative of the broader phenomenon of how individuals exert agency, given structural constraints.     

The origin of black pigmentation in a sample of Mexican prehispanic human bones

The study of black patches and spots in prehispanic bones of Tlatelolco and Tlapacoya is presented. The chosen characterization techniques, X-ray Fluorescence, X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, Infrared Spectroscopy and Gas Chromatography are complementary and they all conclude that the bone black pigment is constituted, mainly, by amorphous carbon and some mineral inclusions. Gas Chromatography and Infrared Spectroscopy show that the pigment is constituted by organic compounds as aromatic hydrocarbons, mainly bitumen. An explanation on how the spots were formed is proposed.     

Household Incomes in Cuban Agriculture: A Comparison of the State,Co-operative,and Peasant Sectors

This article presents the results of a 1991 household income survey of the three main groups in Cuban agriculture: wage workers on state farms, members of production co-operatives, and peasant producers. It is shown that since the 1959 revolution household income levels in the agricultural sector have improved dramatically, while regional differences have been ameliorated considerably. Households in the private sector of Cuban agriculture have fared the best. It is also demonstrated that agricultural households rely on multiple sources of income to generate their livelihood. Rather than being strictly proletarian, collective, or petty commodity producers, these households are best characterized by the multiple class relations in which they participate.
