Our diversity and the Italian Constitution. Do we really need human races?

This paper describes a proposal regarding the presence of the word "race" in the Italian Constitution. Three points are worth of note. Firstly, simply removing the word race from the Constitution is of no real help, since we could miss an indispensable hook for laws concerned with racism. Rather, we should be able to introduce an alternative phrase that: (i) can express the concept of diversity without forgetting all the various aspects of its meaning (biological and cultural, above all); (ii) in no way evokes a hierarchy of values. To make it more effective, the amendment must be accompanied by an explicit statement that race has no meaning for the human species and that any discriminatory view based on such an invalid assumption must therefore be rejected. Secondly, overcoming the old, but still existing, dichotomy between “physical” and “cultural” anthropology, is an absolute necessity in every discussion about the ”human races”. In fact, the term race is also used to stigmatize cultural differences, as if they were the product of different intellectual skills or moral predispositions. Achieving a synthesis between the biological and cultural dimensions of race is a preliminary step to effectively counter the dangerous links between new forms of intolerance and the resurgence of genetic determinism. Thirdly and finally, we should be aware that our commitment must not end simply by signing a document. On the contrary, it must start from there. In our educational and training activities, we must seek to involve wider audiences and provide them with the best tools so they can look at human diversity with no preconceptions. It is important to raise awareness of the need for a change among all those who, for various reasons,are involved in scientific and cultural dissemination

Anthropologists, Italians and “human races”

This article is part of an international forum on raceand racism published by the Journal of Anthropological Sciences and edited by Alan Goodman of the New Hampshire College (USA). The paper presents an overview of the use and meaning of the term "human race" among Italian scholars, both on the biological and cultural side, in a historical perspective. The theme is also contextualized with respect to political and social current events

The emerging complexity of open data dynamics: lessons from human evolutionary Genetics & Genomics

In this lecture, I present an overview of data sharing dynamics with a focus on Human Evolutionary Anthropology. I will first discuss three different views on Open data: "Share or die", "I just don'care" and "Tension between secrecy and openness". Then, I will talk about the complexity surrounding open data dynamics in a relatively small research field, Human evolutionary Genetic and Genomics. Thereafter, I will show some results of empirical studies on the data sharing behavior in human genetics and other scientific disciplines, and describe two cases of good practice (Forensic Genetics and Paleogenetics). Finally, I will discuss the implications of arguments and evidence shown here for the future initiatives of the Associazione Italiana per la Scienza Aperta

Analysis of seismically-isolated two-block systems using a multi–rocking-body dynamic model

A novel multibody rocking model is developed to investigate the dynamic response of two stacked rigid blocks placed on a linear base isolation device. The model is used to investigate the dynamic response of a realistic statue-pedestal system subject to pulse-like ground motions. The analysis shows that, in general, base isolation increases the safety level of the rocking system. However, for large period pulses or small size blocks, the isolator can amplify the ground motion, resulting in a lower minimum overturning acceleration than for the nonisolated system. Further, the amplification or shock spectrum of a linear mass-dashpot-spring oscillator, was found to be the reciprocal of the minimum nondimensional overturning acceleration of the investigated rocking system. Novel rocking spectra are obtained by normalizing the frequency of the pulse by the frequency of the isolator. The analysis also demonstrates how the dynamic response of the two stacked blocks is equivalent to that of a single-block configuration coincident with the whole system assumed monolithic or the upper block alone, whichever is more slender

Samples and data accessibility in research biobanks. An explorative survey

Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnairebased survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7%) and data (85.4%), but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i) the request for applicants to explain what they would like to do with the resources requested; (ii) the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii) the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate

Non-linear dynamic model of a two-bodies vertical spanning wall elastically restrained at the top

Understanding the out-of-plane behavior of unreinforced masonry walls is crucial in seismic assessment of existing buildings. Here, the dynamic response of a vertical spanning strip wall, connected to a flexible diaphragm at the top, is investigated. Despite the simplicity of the model, two rocking rigid bodies elastically restrained at the top, the dynamic response is highly nonlinear. This behavior is due to different phenomena: when in motion the system may assume different configurations, with the transition between them due either to impacts or crack opening caused by ground acceleration. An analytical model capable to capture the complex dynamic response of the system is implemented. The equations of motion are first derived, using variational methods, then the events that the system can undergo during motion are studied. Finally, in order to show the potential of the model, some numerical exemplifications are presented applying an earthquake record and a sine pulse to the system

Structural performance of the Esfahan Shah Mosque

Structural assessment and seismic vulnerability of ancient masonry buildings is a difficult task even when employing advanced specialized technical skills, which requires a complex study. This paper aims to assess the structural and seismic safety of the Esfahan Shah Mosque in Iran by numerically investigating the nonlinear behavior of the mosque for different scenarios and identifying if there is a correlation between crack patterns resulting from numerical analysis, inspection, and historical evidence. First, the numerical model of the mosque is developed and updated using the experimental parameters obtained from a nondestructive test (NDT) campaign that included ambient vibration and sonic testing. Second, the finite element calibrated model is used to evaluate the structural behavior of the mosque under vertical loading, including the influence of the soil and a sensitivity analysis varying the masonry material properties. Besides, the paper discusses the structural behavior of radial stiffening walls that connect the inner and outer domes of the mosque. Finally, pushover analysis was performed to assess the seismic safety of the building and the efficiency of the structural strengthening implemented in the early 20th century. The different technical observations and analyses lead to a better understanding of the double dome and the eyvan (a rectangular space, usually vaulted, walled on three sides, with one end entirely open) as the most vulnerable parts of the structure, which validates the structural strengthening of the 1930s. Yet, improving the connection between the stiffening walls and the two domes could effectively increase the global structural performance of the building.Special thanks to the Esfahan Cultural Heritage Organization, the staff of Meidan Naghsh-e Jahan World Heritage Site, and the restoration workshop of the Shah Mosque to facilitate in situ experimental tests that were supported by the SAHC MSc programme in Structural Analysis of Monuments and Historical Constructions

From the Alps to the Mediterranean and beyond: genetics, environment, culture and the "impossible beauty" of Italy

Since prehistoric times, Italy has represented a bridge between peoples, genes and cultures. Its peculiar geographical position explains why: it is located in the center of the Mediterranean Sea, flanked by the Balkans and the Hellenic Peninsula to the east, Iberia to the west and surrounded by North Africa to the south and central Europe to the north. This makes Italy of extraordinary interest for the study of some different aspects of human diversity. Here we overview current knowledge regarding the relationships between the structure of the genetic variation of Italian populations and the geographical, ecological and cultural factors that have characterized their evolutionary history. Human presence in Italian territory is deeply rooted in the past. Lithic artifacts produced by the genus Homo and remains of Homo sapiens are among the earliest to have been found on the continent, as shown by the lithic industry of Pirro Nord (between 1.3 and 1.6 Mya) and the dental remains of the "Grotta del Cavallo" (between 45 and 43 Kya). Genetic and genomic studies relating to existing and extinct human groups have shed light on the migrations from Europe, Africa and Asia that created the ancient layers of the genetic structure of today's Italian populations, especially before the Iron Age. The important role of isolation (genetic and cultural) in shaping genetic structure is clearly visible in the patterns of intra- and inter-population diversity observed among Italian ethno-linguistic minorities that settled on the peninsula and on the major islands until the 19th century. Finally, selective pressures have likely driven the distribution of originally adaptive variants and haplotypes that now confer protection or susceptibility to major diseases such as diabetes and cardiovascular disease (in northern Italy) and tuberculosis and leprosy (in the south). What emerges is a picture where the combined effects of migration, isolation and natural selection generated by the interplay of geography, environment and culture have shaped a complex pattern of human diversity that is unique in Europe and which goes hand in hand with today's rich animal and plant biodiversity. In a nutshell, scientific evidence and cultural heritage paint Italy as a place with extremely diverse environments where distant peoples have met since the deep past, bringing and sharing genes and ideas
