The spatial scope of agglomeration economies in Brazil

This paper provides evidence about location and colocation patterns of manufacturing entrepreneurship and spatial scope of agglomeration economies in the context of a developing country. Using microgeographic data for all Brazilian manufacturing activities and distance-based measures, we find clear patterns of colocalization between entrants and existing establishments, and that these patterns occur mainly at short distances. For activities presenting colocalization between entrants and existing establishments, our results also indicate that a greater number of incumbent establishments in a given location positively affects the number of entrant establishments that decide to locate there, an effect that attenuates rapidly with distance (generally disappearing after 5 km). This pattern of attenuation is robust to both the inclusion of a comprehensive set of controls for observable and unobservable local characteristics and the use of instrumental variables to address remaining endogeneity concerns.     

Economic fears of mass migration from southern Italy in early twentieth century America

ABSTRACT

Economic fears in the early twentieth century America about Italian immigration united trade unions and white collar workers and were motivated by reasons that ranged from the belief that migrants were disrupting the labour market and were temporary opportunist earners, unwilling to integrate and living in isolated communities, to the idea that southern Italians did not offer sufficient human capital: they were mainly illiterate, and had high dropout rates in schools, and were widely believed to have children with mental disabilities. These American fears were wildly overstated, however. First, Southern Italian migrants had to undergo a two-stage positive selection for literacy, while, secondly only 28.4 per cent of the massive incoming flow of Italians decided to stay; most Italian immigrants chose to return to their country of origin and the minority who remained did not delay long to join in the American melting pot.     

The Persistence of the Black Colour in Magnetite‐Based Pigments in Prehispanic Ceramics of the Argentine North‐West

The persistence of the black colour in magnetite‐containing paints in polychrome ceramics of the Argentine North‐West processed under conditions considered as oxidant has generated questions about ancient production technologies. In this work, the thermal oxidation reaction of magnetite to hematite under different temperatures, atmospheres and physicochemical characteristics of the materials is experimentally evaluated. The causes of this behaviour are elucidated, and it is concluded that in the archaeological context, a double‐firing process was not necessary to achieve the coexistence of different colours.     

New venture high growth in high-tech environments

The aim of this article is to understand the triggering factors of new firm growth in high-tech environments (life science, knowledge-intensive business services [KIBS] and engineering) by studying a representative sample of high-growth Italian start-ups. Our empirical research uses the information gathered during direct interviews with managers through a semi-structured questionnaire, which was presented to 382 new Italian firms. Considering the characteristics of new firms, this article summarizes the key growth factors. Investment in acquiring new competencies both in technology and marketing, development of dynamic capabilities (investment in human resources and new routines) and access to external knowledge and information sources emerged as significant.     

Effect on the Structure in Elevation of Wood Deterioration on Small-Pile Foundation: Numerical Analyses

Wooden pile foundations are quite common in Venice historical building. Very short, small-diameter piles are embedded into the soft shallowest soil layer under the groundwater level, but wood degradation is not prevented as anaerobic bacteria can flourish even in anoxic condition. This study couples the behavior of the masonry structure and the foundation as result of pile degradation. The numerical analyses, relative to the ancient piling, consider wood decay and secondary settlement of soil. The effect of deterioration as a function of the pile spacing and the possible presence of a stiff layer under pile tips are also investigated. The geotechnical results are then used as input for the structural model. The behavior of the masonry as result of different states of wood conservation along the wall is studied numerically.     

Injection Grouts for the Re-Attachment of Architectural Surfaces with Historic Value—Measures to Improve the Properties of Hydrated Lime Grouts in Slovenia

In the described studies with the aim of optimizing hydrated lime grout composition, the first measure was to reduce the water content of the grout using a highly efficient polycarboxylate ether-based superplasticizer, whereas the second measure was to increase the content of the inert limestone filler with an adequate grain size distribution. In this way, an attempt was made to achieve the best possible volume stability and strength properties of the hydrated lime grout, while continuing to fulfill the other necessary requirements regarding non-structural grouting works which are reported in the literature.

The results of the tests showed that a non-structural grout consisting of 1 volume part of hydrated lime CL 90-S and 3 volume parts of inert limestone filler, with 0.5% of the polycarboxylate ether based superplasticizer, fulfilled most of the established requirements, so that it is thus potentially suitable for re-attachment interventions on architectural surfaces.     

The Jew,the Blood and the Body in Late Medieval and Early Modern Europe

The reality of the blood libel legend and accusations of ritual murder against Jews in medieval and early modern times has been widely discredited by scholars. They demonstrate instead the processes by which the exclusion of a perceived ethnical and religious enemy strengthened the communal identity of European society at that time. The aim of this paper is to look at the alleged bodily evidence of the libel—the blood—and at the controversial way in which it has been perceived by different groups of people over time. This approach illuminates the fears and beliefs that fed hatred of Jews beyond its original manifestation as a religious motif in relation to the crucifixion of Christ.

The Evolution of Population Distribution on the Iberian Peninsula: A Transnational Approach (1877–2001)

Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.
