Giuseppe Levi: mentor of three Nobel laureates

Giuseppe Levi (1872-1965), Professor of Anatomy at the University of Turin, had broad research interests and was a pioneer of in vitro studies on cultured cells. He provided a number of contributions on the nervous system, especially on the plasticity of sensory ganglion cells. An influential and magnetic teacher and mentor, he gathered around him a large group of brilliant students. He has the peculiar primate to count among his students three Nobel laureates in Physiology or Medicine: Salvador Luria, Renato Dulbecco, and Rita Levi-Montalcini. For all three of them, the internship in Levi's laboratory provided an exceptional initial stimulus. They remained in close contact with each other and with Levi even after the 1940s when they migrated to the United States for political and racial reasons, engaging in different fields of research. Rita Levi-Montalcini, who was awarded the Nobel Prize (1986) for the discovery of Nerve Growth Factor, was stimulated and assisted in her work by Giuseppe Levi during the difficult years of World War II. With Giuseppe Levi, she pursued early studies on the relationships between neural centers and their peripheral target of innervation, and she has witnessed in her writings the enthusiasm of her mentor.     

A historical review of investigations on laterality of emotions in the human brain

Different models of emotional lateralization, advanced since the first clinical observations raised this issue, will be reviewed following their historical progression. The clinical investigations that have suggested a general dominance of the right hemisphere for all kinds of emotions and the experimental studies that have proposed a different hemispheric specialization for positive vs. negative emotions (valence hypothesis) or for approach vs. withdrawal tendencies (motivational hypothesis) will be reviewed first and extensively. This historical review will be followed by a short discussion of recent anatomo-clinical and activation studies that have investigated (a) emotional and behavioral disorders of patients with asymmetrical forms of fronto-temporal degeneration and (b) laterality effects in specific brain structures (amygdala, ventro-medial prefrontal cortex, and anterior insula) playing a critical role in different components of emotions. Overall, these studies support the hypothesis of a right hemisphere dominance for all components of the emotional system.     

Italy's political system since 1989

This essay follows the development of the Italian political system over the last twenty-five years, starting from the collapse of the principal political parties that had previously dominated the history of the Republic. In institutional terms, it seems legitimate to describe this as a transition, since the outcomes of initiatives to reform the electoral system, to abolish the previous system of ‘perfect bicameralism’, and reshape relations between the State and the regions are still unknown. But I argue that many fundamental changes in the relationship between the country and its political system were already evident in the 1980s.     

We Branded Ourselves Long Ago: Intangible Cultural Property and Commodification of Fijian Firewalking

ABSTRACT The Fijian firewalking ceremony (vilavilairevo), traditionally performed only by members of the Sawau people on the island of Beqa, is a prime example of a propitiation ritual that has become commodified to suit the requirements of tourism. The Sawau ‘gift’ of walking on white‐hot stones introduces another dimension of the gift practice. Although gifts and commodities are often treated as ideal‐type opposites, and a tradition of Melanesian scholarship has focused attention on the inalienability of gifts, I argue that the self‐consciously traditional firewalking practice of Beqa Island, Fiji, is an inalienable sui generis commodity that becomes effective by ‘branding’ Fijian concepts of different places' distinct custodianships. Over the last two centuries, the gift of firewalking has transmuted itself into a sociocultural tool that has consistently indigenized the power of the foreign. The gift of firewalking has allowed its custodians to locally sustain their community, to gain a reach and respect across the nation and beyond, and to intensify the group's social sentiment and social capital.     

HISTORICAL TRADITIONS OF CIVICNESS AND LOCAL ECONOMIC DEVELOPMENT*

ABSTRACT The paper investigates the importance of history for local economic performance in Italy by studying the role of social capital, which refers to trust, reciprocity and habits of co‐operation that are shared among members of a local community. The paper presents a test based on worker productivity, entrepreneurship, and female labor market participation. Using as instruments regional differences in civic involvement in the late 19th century and local systems of government in the middle ages, it shows that social capital does have economic effects.     

Proposing new approaches for dating young volcanic eruptions by luminescence methods

The application of luminescence dating to young volcanic sediments has been first investigated over three decades ago, but it was only with the technical innovations of the last decade that such analyses became viable. While current analytical procedures show promise for dating late Quaternary volcanic events, most efforts have been aimed at unconsolidated volcanic tephra. Investigations into direct dating of lava flows or of non-heated volcanoclastics like phreatic explosion layers, however, remain scarce. These volcanic deposits are of common occurrence and represent important chrono- and volcanostratigraphic markers. Their age determination is therefore of great importance in volcanologic, tectonic, geomorphological and climate studies. In this article, we propose the use of phreatic explosion deposits and xenolithic inclusions in lava flows as target materials for luminescence dating applications. The main focus is on the crucial criterion whether it is probable that such materials experience complete luminescence signal resetting during the volcanic event to be dated. This is argued based on the findings from existing literature, model calculations and laboratory tests.     

Camouflaging Consumption and Colonial Mimicry: The Materiality of an Eighteenth and Nineteenth-Century Nipmuc Household

This article serves as an interpretation of Nipmuc history in colonial contexts by focusing on the engagement and survival of the “capitalist colonial” world by the eighteenth- and nineteenth-century Nipmuc inhabitants of the Sarah Boston Farmstead Site in Grafton, Massachusetts. Ceramic analyses are drawn upon to argue that active consumer strategies and/or choices may potentially undermine the material and discursive markers of difference linked to notions of domesticity, class and race. The apparent homogenized or “insignificant” character of the Sarah Boston Farmstead ceramic assemblage is argued to in fact be quite significant, as its banality speaks to a degree of knowledgeable “mimicry”—tactical or not—that may have deflected (but not negated) inequality through the undermining of markers and discourses of difference.     

A Probability-based Approach for the Definition of the Expected Seismic Damage Evaluated with Non-linear Time-History Analyses

The seismic damage evaluated through Nonlinear Time-History Analyses is significantly affected by the response quantity chosen to represent the seismic responses. Starting from the theory of tolerance regions, a generic upper limit of the seismic responses is proposed. The method is applied to a reinforced concrete structure subjected to different record combinations. For each considered damage index and record combination, the upper limit damage is compared with the average value suggested by seismic codes. The proposed method yields a higher seismic damage than the average response and an increase in the damage indices as the number of records decreases.     

Networks Mobilized to Access Key Resources at Early Stages of Biotech Firms: A Comparative Analysis in Two Moderately Innovative Countries

This paper investigates the networking behaviour of biotechnology start-ups in peripheral locations. The aim is to understand whether the conditions found in this type of environment introduce some specificities in the networking process, namely in network building and early mobilization to access key resources. The paper compares biotechnology start-ups in Portugal and in Southern Italy, focusing on relationships with research organizations and on the relevance assumed by international connections, and investigating the role played by entrepreneurs’ personal networks. The research identified some common features that diverge from the typical biotechnology start-up behaviour and can be regarded as firms’ adaptive responses to the conditions faced. Notwithstanding the frequent presence of close connections with local research organizations—that often play functions that go much beyond that of a knowledge source—the local environment is a lesser determinant for a substantial proportion of firms than would be expected in start-ups. A distinctive feature of these firms is an extensive reliance on foreign sources, for different purposes and from the very early stages. Entrepreneurs’ personal networks are found to be instrumental, both to identify and obtain knowledge in the vicinity and to support the establishment of more complex distant relationships.
