Opis:
In the last decades of the twentieth century, the concept of agency – i.e., purposeful self-determination based on calculated choice – enjoyed a hegemonic position in the literature of the social history of European immigration to the United States. The original inspiration for this development in immigration historiography was the path breaking 1964 essay by essay by Rudolph Vecoli challenging the classic work on Oscar Handlin, The Uprooted (1951), which saw immigration as a jarring experience of alienation and confusion that left immigrants defensive and poorly adjusted in their new American homes. This essay reexamines the conflict of views associated with Vecoli’s challenge to Handlin in two contexts. One is the conceptual and empirical foundations of immigration historiography, and the second is the origin and early development of the New Social History, in British and American labor history and in the history of African American slavery and in Western neo-Marxism thought, which sought a humanist alternative to Communist ideology. The essay seeks critical engagement with agency, and advances the view that we should open ourselves once more to seeking guidance in Handlin’s interpretive understandings, which also suggests a reevaluation of the contributions of Thomas and Znaniecki’s The Polish Peasant in Europe and America, the now century-old source of Handlin’s views.

Opis:
Ballast layer has weighty share in the lifecycle costs of railway track. The strict standards and maintenance rules of ballast grading significantly contribute to the ballast costs. One ways to the costs reduction is differential demands to ballast grading for the secondary and low loaded railway lines. Additional one is the different ballast grading over the ballast height. This study presents a full scale laboratory investigation of technical efficiency of such railway ballast under the long-term cyclic loading in comparison with the standard ballast layer. The double layer is presented with standard grading ballast upper layer and bottom sub ballast layer consists of ballast mixture. Pressure distribution under the ballast layer and permanent settlements of the layers are measured during the loading cycles. The reference measurements with standard grading ballast material are carried out. The study shows that initial settlement accumulation of the double layer railway ballast are lower to that of the standard ballast layer. However, the settlements accumulation intensity of the ballast is higher. The analysis of the pressure distribution measurements under the ballast layer and the settlements inside the ballast layer explain the causes of the different settlement accumulation.
