Making Sense of Social Change: Observing Collective Action in Networked Cultures

This article presents an overview of rising trends in the study of networked interactions conveyed by social media technologies and the emergence of new meanings associated with social change. In recent years, a healthy amount of studies has focused on ICT uses within collective action, considering social media tools to have become crucial components of many transnational movements and social change projects. Crossing boundaries between social movements theories, political science, and communication studies, literature suggests that ‘online activism’ and increasingly networked interactions may have transformed the meanings and definitions associated with ‘collective action’ and ‘social change’. To make sense of these meanings, we identify three approaches used by scholars, which focus on (i) the actual networking of actors, (ii) the diffusion of new repertoires and frames through networks, and (iii) making sense of new meanings conveyed within networked cultures. We conclude by suggesting the need for more comprehensive research to better observe and make sense of how's actors define collective action and how they use social media tools when striving to convey social change.     

Generations and Motivations: Russian and other Former Soviet Immigrants in Costa Rica

GÉNÉRATIONS ET MOTIVATIONS : IMMIGRANTS RUSSES ET AUTRES IMMIGRANTS EX-SOVIÉTIQUES AU COSTA RICA
Nous examinons dans cet article le rôle qu'ont joué les réseaux sociaux dans la migration et l'installation des immigrants russes et autres immigrants de l'ex-Union soviétique au Costa Rica. Ce groupe d'immigrants est particulièrement intéressant en ce qu'il constitue un exemple de migration à partir d'une ex-nation communiste dans un pays du tiers-monde et non dans un pays riche (États-Unis ou pays européen). De plus, des femmes soviétiques qui ont épousé des Costariciens vers la fin des années 1970 sont à l'origine de cette migration. Notre recherche avait pour objectif d'examiner la structure et la signification de ces réseaux sociaux d'immigrants ainsi que le rôle qu'ils jouent dans le pro-cessus de migration et pendant l'installation. Les résultats donnent à penser qu'il existe une différence significative dans la forme et la fonction des réseaux sociaux des immigrants arrivés avant 1991 (pendant l'époque soviétique) et de ceux qui sont venus après 1991 et à la suite de l'effondrement de l'Union soviétique.     

Addressing disproportionality through undoing racism, leadership development, and community engagement

In 2005 the Texas 79th legislature passed Senate Bill 6, which included mandates to address disproportionality. This article will describe how the Texas Department of Family Protective Services in collaboration with Casey Family Programs' Texas State Strategy systems improvement initiative is addressing disproportionality statewide through promising practices and innovations in undoing racism trainings, values-based leadership development, and community engagement strategies.     

The relevance of social and cultural contexts: Religiosity,acculturation and delinquency among Korean Catholic adolescents in Southern California

Although research shows an inverse relationship between religiosity and delinquency, this association is not well understood. Scholars have attempted to explicate these findings in a number of ways, including arguments that: (1) the religiosity–delinquency relationship is limited to certain types of delinquency, (2) other theoretical variables explain or interpret the relationship, and (3) the relationship is stronger in the context of what are termed moral communities. We address these issues using a sample of Korean-American adolescents attending Catholic Sunday school. Within this relatively homogeneous moral community, one religiosity measure demonstrates an initial inverse association with three different delinquency measures, but the inclusion of control variables renders this relationship spurious. Additional results show that acculturation increases delinquency as well as interacts with religiosity to influence delinquency.     

Inspection errors in link sampling

Results of an investigation into the sensitivity to two types of inspection error of link sampling procedures described by Harischchandra and Srivenkataramana are reported. Relevant compound distributions are derived. Some comparisons with results obtained in a similar investigation for standard double sampling are also given.     

Dorfman-sterrett screening (group testing) schemes and the effects of faulty inspection

The Dorfman screening procedure is based on first testing a group of items as a whole, proceeding to individual testing only if the group-test indicates existence of at least one nonconforming item. A modification suggested by Sterrett allows for reintroduct-ion of group testing of all items, not yet tested individually, when an item is classified as nonconforming by an individual test. Effects of faulty test inspection on the properties of the modified procedures are studied.     

Road trafficking description and short term travel time forecasting,with a classification method

The purpose of this work is, on the one hand, to study how to forecast road trafficking on highway networks and, on the other hand, to describe future traffic events. Here, road trafficking is measured by vehicle velocities. The authors propose two methodologies. The first is based on an empirical classification method, and the second on a probability mixture model. They use an SAEM‐type algorithm (a stochastic approximation of the EM algorithm) to select the densities of the mixture model. Then, they test the validity of their methodologies by forecasting short term travel times.     

A note on synthethic cohort estimates of average desired family size

Abstract This note considers the problem of estimating average desired family size from parity-specific data on proportions wanting another child. Three procedures proposed in the literature are reviewed and shown to give seriously biased estimates, when women implement their fertility preferences. An alternative procedure is proposed which overcomes most of the deficiencies of previous methods. An example from Sri Lanka illustrates the fact that the differences among the methods may be quite substantial.     

U.S. Deportation Policy,Family Separation,and Circular Migration

Since the mid‐1990s the United States has enacted a series of laws that make it easier to deport noncitizens. Drawing on findings from interviews with a random sample of 300 Salvadoran deportees, we examine how family relations, ties, remittance behavior, and settlement experiences are disrupted by deportation, and how these ties influence future migration intentions. We find that a significant number of deportees were long‐term settlers in the United States. Many had established work histories and had formed families of their own. These strong social ties in turn influence the likelihood of repeat migration to the United States.
