In movimento: ‘contamination’ in action and the Italian Global Justice Movement

Abstract In this article we explore the process of ‘contamination’ (namely cross‐fertilization) in the development of the Global Justice Movement in Italy during the 1990s. We focus on two specific organizational sectors of this movement: labour organizations and associations for solidarity with the global South. We concentrate on a stage of the protest cycle that has been overlooked in social movement studies, namely the emergence of mobilization after a period of latency, and shed light on the process through which individual and organizational networks actually facilitate mobilization and vice versa. The process of ‘contamination’ in action is presented as the combination of structural, cognitive and affective mechanisms. It operates through both individual and organizational networks that together facilitate logistic coordination, enable the emergence of tolerance and mutual trust and allow frame bridging and the transnationalization of identities.     

Transformations of Old Colony Mennonites: the making of a trans‐statal community

Through an analysis that combines the historical development of the Old Colony Mennonites, which covers their migrations from sixteenth‐century Europe to late twentieth‐century Latin America, with ethnographic field work in Bolivia and Argentina, I examine the genesis and maintenance of a religiously based trans‐statal community. I argue for the conceptual maintenance of a clear distinction between transnational and trans‐statal processes in understanding the cross‐border practices of Old Colony Mennonites. Mennonites do not move in and out of nations but between the territories over which different states claim sovereignty. I further show that the trans‐statal practices of Old Colony Mennonites are a strategic means of outmanoeuvring states in their imposition of national identities within a context of nation‐states being the dominant political formation. The case contributes to the call for a shift in emphasis from nations to faith communities in transnational and trans‐statal studies.     

Explaining the Emergence Process of the Civil Rights Protest in Northern Ireland (1945–1968): Insights from a Relational Social Movement Approach1

Abstract This article explains how the contingent of complex interactions among pre-existing structural settings, institutional constraints, processes of regional and international transformative events, and uniquely combined developments within and between different contenders in the aftermath of the Second World War shaped Northern Ireland socio and political relations and thus instigated the Civil Rights Movement mobilization process. By re-introducing the time-space context into our studies of collective action, through a relational reading, my intent first is to advance our understanding of those episodes and complex patterns of interaction that give rise to social movements, and second to move beyond the static movement-centric approach explanation and away from the a-historical nature of much of the social movement literature. My historical-sociological research, into the longitudinal case study of the Northern Ireland Civil Rights Movement mobilization, involves secondary and new empirical primary sources, such as archival analysis, qualitative examination of Northern Ireland daily newspapers during the 1960s, and the collection of 35 semi-structured interviews with key players from the Civil Rights Movement.     

A Class of Normalized Random Measures with an Exact Predictive Sampling Scheme

Abstract. In this article, we define and investigate a novel class of non‐parametric prior distributions, termed the class . Such class of priors is dense with respect to the homogeneous normalized random measures with independent increments and it is characterized by a richer predictive structure than those arising from other widely used priors. Our interest in the class is mainly motivated by Bayesian non‐parametric analysis of some species sampling problems concerning the evaluation of the species relative abundances in a population. We study both the probability distribution of the number of species present in a sample and the probability of discovering a new species conditionally on an observed sample. Finally, by using the coupling from the past method, we provide an exact sampling scheme for the system of predictive distributions characterizing the class .
