“If in Truth You are Odysseus” – Distrust and Persuasion in the Odyssey†

When Odysseus decides in the course of the Odyssey finally to reveal his true identity to a few chosen characters, he regularly meets with deep scepticism. The depth of this distrust is to no small degree owed to the unusually long duration of Odysseus’ absence and the concomitant loss of familiarity. With the typical skill of a versatile narrator, Homer subtly brings out the nature of the psychological gap in each case and shows the means by which it can eventually be overcome. The paper addresses the salient points and main characteristics of the relevant recognition scenes and ends by suggesting an explanation for the feature that some of Odysseus’ interlocutors tend to suppress his name for some time while others do not.     

Nicotine in the hair of mummies from San Pedro de Atacama (Northern Chile)

The consumption of plant-derived hallucinogenic substances through smoking and snuffing is a long-standing tradition in the south-central Andes. Chemical and archaeobotanical evidence point to the consumption of nicotine and tryptamine alkaloids in Northwestern Argentina and of tryptamine alkaloids in San Pedro de Atacama (SPA), in prehispanic times. In this paper, results are reported of gas chromatography–mass spectrometry (GC/MS) analyses aimed at identifying nicotine and tryptamine alkaloids in the hair of mummies from different cultural periods of SPA. Fifty-six samples were examined. While tryptamines were not found in any of the samples, nicotine was found in 35 samples, assigned to the Late Formative (1 of 1 sample from this period), Late Formative or Middle (1 of 2 samples from either of these periods), Middle (4 of 6 samples from this period) and Late Intermediate periods (8 of 12 samples from this period), or without assignment to period due to lack of contextual information (21 of 35 samples unassigned to a period). These results show a continuous consumption of nicotine from the Late Formative to the Late Intermediate periods of SPA (ca. 100 B.C.–1450 A.D.). No associations were found between presence of nicotine in the hair of mummies and presence of snuffing trays or of other snuffing paraphernalia in the corresponding tomb; furthermore, neither the diversity of the funerary context, measured in terms of the number of types of objects, nor the presence of gemstone necklaces differed between tombs with mummies with or without nicotine in their hair. Overall, these results suggest that consumption of nicotine was performed by members of the society at large, irrespective of their social and wealth status.     

The origin and construction of pre-Hispanic mounds in the Upper Delta of the Paraná River (Argentina)

Pre-Hispanic mounds, known as “cerritos,” “cerritos de indios,” or “aterros” across southeastern South America, are one of the most conspicuous and well-studied cultural manifestations in lowlands archaeology. Nevertheless, in the Upper Delta of the Paraná River, mounds are rarely studied, and even their anthropic origin is under debate. This could be related to the fact that anthropogenic mounds are located on a floodplain where other “mound-like” natural geoforms (generated by fluvial processes) are also present. In addition to this, the natural geoforms also contain evidence of Holocene human occupation (sherds, bones, charcoal, humans burials, etc.), which can lead to interpretive errors of their origin and formation. Thus, this project set out to determine the genesis and evolution of these mounds and also to identify the cultural occupation and transformation of natural landforms found in the area. In this article, natural and anthropogenic systems and processes were identified and characterized through the application of proxy record analysis (i.e., sediment composition, stratigraphy, micromorphology, silica bodies and chronological analysis) at the Los Tres Cerros archaeological locality in the Upper Delta of the Paraná River of Victoria County, Entre Ríos Province, Argentina. This analysis allowed for the recognition of natural anthropogenic interfaces, such as the “pre-mound” occupation as well as evidence of cultural activities such as mound construction, between 1,000 and 500 ¹⁴C years bp. These findings were integrated into current research on the variability of mound construction during the Late Holocene in the lowlands of South America.     

Living with everyday environmental risks: giving a voice to young people in the design of community-based risk communication programs in the city of San Luis Potosí, México

Risk communication programs (RCPs) can contribute to the improvement of community health in marginalized settlements by improving health-related information and practices. Yet, there is a need to include young people's concerns in the design and implementation of RCPs. This study analyses young peoples’ risk perceptions in the city of San Luis Potosí, Mexico, using visual methods such as drawings and photography. Research was conducted with 74 students from two deprived urban neighborhoods. Results indicate that the use of visual techniques enabled them to identify environmental health risks such as unhealthy sedentary habits and the exposure to hazardous items. We conclude that visual methods may help young people to critically reflect on everyday elements in their environment that affect their well-being. By giving them a voice in a reflexive way, visual methods may engage young people as key multipliers in the awareness raising process, and promote their sense of everyday agency.     

The veterans' movement and First World War memory in Portugal (1918–33): between the Republic and Dictatorship

The lack of consensus regarding Portugal's participation in the First World War's European front, combined with the post-war political and economic crisis, highlights the difficulty of integrating a large number of mobilised men, mainly rural workers, who now found themselves unemployed and physically and psychologically traumatised. The return, reaction and insertion of soldiers would configure the social and political milieu in which, in the immediate aftermath of the war, the first images of the conflict were built, based on interactions between veterans and the political authorities, not always on an equal footing. This study will first seek to identify the context and external elements so as to trace a concrete and immediate profile of the veterans. Secondly, it will analyse the creation and intervention of associations – their active social ‘intervention’ – amidst their internal activities and attempts to shape public opinion – actively making demands – in order to influence State policy. Finally, this text will attempt to shed light on the relationship between veterans and contemporary political dynamics, especially keeping in mind the eventual militancy of their actions.     

Experimental and Numerical Seismic Response of a 65 kW Wind Turbine

A full-scale shake table test is conducted to assess the seismic response characteristics of a 23 m high wind turbine. Details of the experimental setup and the recorded dynamic response are presented. Based on the test results, two calibrated beam-column finite element models are developed and their characteristics compared. The first model consists of a vertical column of elements with a lumped mass at the top that accounts for the nacelle and the rotor. Additional beam-column elements are included in the second model to explicitly represent the geometric configuration of the nacelle and the rotor. For the tested turbine, the experimental and numerical results show that the beam-column models provide useful insights. Using this approach, the effect of first-mode viscous damping on seismic response is studied, with observed experimental values in the range of 0.5–1.0% and widely varying literature counterparts of 0.5–5.0%. Depending on the employed base seismic excitation, damping may have a significant influence, reinforcing the importance of more accurate assessments of this parameter in future studies. The experimental and modeling results also support earlier observations related to the significance of higher modes, particularly for the current generation of taller turbines. Finally, based on the outcomes of this study, a number of additional experimental research directions are discussed.
