Summary

In the 1780s the anatomist Vincenzo Malacarne discussed the possibility of testing experimentally whether experience can induce significant changes in the brain. Malacarne imagined taking two littermate animals and giving intensive training to one while the other received none, then dissecting their brains to see whether the trained animal had more folds in the cerebellum than the untrained one. This experimental design somewhat anticipated one used 180 years later by Mark R. Rosenzweig at the University of California, Berkeley. This paper explores some methodological aspects of the case study just outlined by pointing out that our grounds for being interested in it are neither merely neuroscientific (for, strictly speaking, Malacarne's proposal was false) nor narrowly historical (for there is no causal chain linking Malacarne's ideas to Rosenzweig's experiment). Rather, the really interesting point here is to what extent Malacarne's ideas are similar to Rosenzweig's, a point that we can better investigate by employing certain conceptual tools borrowed typically (but not exclusively) from (a certain kind of) philosophy. If we do not handle the analogy with care, we run the risk of ‘discovering’ nothing but void platitudes or anachronistically misleading common features.  相似文献

The article aims to reconsider the history of Ottoman Transjordan during the second half of the nineteenth century. Istanbul's decision to impose its direct control over this province triggered a process of evolution and change within local political spaces. The traditional balance of power was altered and tribes were forced to accept the authority of the Ottoman Empire. States and tribes were not the only political actors. Christian religious institutions also participated in the dynamics of change. The article reconsiders the history of a Christian village of Transjordan, Madaba, to describe the complex relationship between tribes and Christian religious communities during this period of change and evolution. The section Karak highlights the main aspects that characterized the refoundation of Madaba. In the section The Exodus and the Rebirth of Madaba, the exodus of several Christian tribes from Karak to Madaba is analyzed to explain the overlap and intertwinement between the different cultural horizons and sociopolitical logics of the two actors. The section The Village of Madaba analyzes some episodes of daily life in Madaba to detail the consequences of the interaction between tribes and religious communities. Finally, the functioning of the local sociopolitical space on which the Hashemite emirate was later founded is explained. The religious community‐tribe dyad was, in fact, part of the transition from “the tribe to the state.”  相似文献

This paper reports on the discovery in the Thames Estuary and the partial recovery and recording of the remains of a 19th‐century Tyne‐built paddle tug. The wreck is believed to be that of Admiral built in Newcastle in 1870 and sunk following a collision in the estuary in 1872. This unexpected discovery provided a rare opportunity to examine the archaeological assemblage of one these once‐familiar working vessels and revealed the continuities and innovations of a specific type of engine used on paddle tugs.  相似文献

Two examples of monitoring systems of great Venetian Cathedrals, are presented. The first, concerning the Basilica of San Marco, is an example of a long-term monitoring system for a structure that has not undergone any strengthening intervention. The criteria for interpreting this monitoring system data are illustrated. The second example, concerning the Basilica of S. Maria Gloriosa dei Frari, is a clear example of the use of monitoring during the execution of strengthening intervention. This study illustrates the interventions that were carried out on the supporting structures: consolidation of the soil foundation of the bell tower by using the soil-fracturing technique and creation of a structural joint between the bell tower and the Basilica. Through the observational method, this monitoring system was able to check the structural behavior during all the phases of the interventions, thus becoming a precious design tool able to guarantee the safety of the structure and to modify the design solutions during the strengthening intervention, according to the real deformation behavior observed through the monitoring system.  相似文献

This contribution is organized along two main interpretive lines. First: the Italian public sphere is very polarized because of well-established historical attitudes, a crowded media market and new technologies that push towards segmentation of the audience. The arrival of Berlusconi has only reinforced the already existing polarization that goes well beyond the borders of partisanship involving the content of news, the structure and professionalism of news outlets and also the recipients that divide themselves along the lines of political attitudes. The second characteristic feature of the Italian public sphere involves the tendency towards dramatization, which is also produced by the sudden commercialization of the entire mass media system that started in 1980. This article's thesis is supported by examples of dramatization and extreme political discourse. The consequences that derive from this situation are discussed in the conclusion.  相似文献

A criterion is proposed for deciding whether, after a damaging mainshock, a bridge can still be open for either emergency or ordinary traffic. The criterion is based on the comparison between the collapse risk of the mainshock-damaged structure and the pre-mainshock risk of the intact structure. The approach requires fragilities for multiple damage states for the intact structure, and transition probabilities from these states to collapse for the damaged structure. The aftershock risk decreases with time, hence a decision for reopening might have to wait until the risk level goes down to an acceptable value. A realistic application demonstrates the approach.  相似文献

The aim of this study was to propose an extension of the displacement-based assessment procedure for infilled reinforced concrete (RC) frames. Two fundamental steps of the displacement-based approach were studied: the determination of the equivalent viscous damping and the definition of the limit-state displacement profile. The proposed criteria were derived by examining the results of two different numerical investigations regarding the nonlinear seismic response of single- and multi-story infilled RC frames. Lastly, the effectiveness of the method was verified through comparisons, in terms of displacement demand, with the results of nonlinear dynamic analyses.  相似文献
