A new dataset created from the first 18,000 savings accounts opened (from 1850 to 1858) at the Emigrant Industrial Savings Bank in New York City is described. The bank was founded by Irish Americans, and most of its depositors in its first decade of operations were recent Irish immigrants. The data offer a unique window on both savings behavior by the poor and not-so-poor in antebellum New York and on how emigrants who came primarily from rural parts of Ireland adapted to urban life. They also contain much that is new on the regional origins of mid-nineteenth century Irish immigrants and on their settlement patterns in New York. 相似文献

In this study, we present a novel, safe method for how to remove inorganic components from soil samples studied for archaeological purposes, in order to improve studies of the distribution of black carbon in the sedimentary record. As the depositional history of this material depends on the interaction between humans and the natural environment, this method can be widely used in archaeology, landscape archaeology, palaeoecology, environmental geology and sedimentology. Our method does not require the use of dangerous hydrofluoric acid, which is commonly used for the removal of silicon oxide from such samples; therefore, this procedure allows even less chemically trained scientists to analyse soil samples with an increased level of work safety. 相似文献

Single and double flat-jack tests are presently used widely for assessing the mechanical characteristics of stone masonry. This technique remains as one of the most versatile in situ test procedure for the estimation of the main mechanical properties of masonry walls. Nevertheless their application is still controversial due to the difficulty of accepting in some cases the results as reliable. This article presents and discusses the results of an experimental campaign resorting to flat-jack technique carried out with the scope of the rehabilitation process of the historical city center of Coimbra. 相似文献

ABSTRACT This article examines the royal acclamation ceremonies of the Portuguese crown in order to grasp the responsiveness of the institution of the monarchy and regime to the challenges of modernity throughout the delicate watershed period of the late eighteenth and nineteenth centuries. The Portuguese Catholic and absolutist monarchy of the ancien régime had a strict protocol and a set of insignia of power that acted together at the moment of the acclamation and legitimation of each new king. The purpose of this research is to assess the adaptation and reinvention of these insignia and rituals according to the revolutionary demands of social change and secularization brought about by the turbulent period of the beginning of the nineteenth century: the French military invasions (1807–11); the departure of the royal family, court and administration to Brazil (1807); the liberal constitutional revolution (1820); and the civil war pitting liberals against absolutists (1832–34). The new constitutional monarchy that came out of this revolutionary flow faced many challenges of legitimacy, including the test of its capacity to create a modern royal imaginary updated to the cultural mindset of national and secular societies, and capable of bonding rulers with their people. The authors believe that the study of the acclamation ceremonies in the Portuguese constitutional monarchy can give us an accurate perspective on the quality of the symbolic image of the crown, therefore assessing the political efficiency of rituals as one of the structural aspects for institutional legitimization. 相似文献
