Social capital exchanges in voluntary associations and work organizations: A network perspective

Organizations have been an important setting in which social capital exchanges (SCEs) occur, but little work has been done to distinguish two predominant species of organizations in the social network literature: voluntary associations and formal work organizations. Addressing this lacuna, this article comparatively examines how the two organizational species differ in (1) how two prominent types of SCEs operate (restricted and generalized exchange), as well as (2) the analytical approaches and methodological tools for studying SCEs (boundary-specification, sampling, network designs, tie-recording methods) and their adherent implications for network structure (networking conditions and homophily). This article concludes by identifying methodological and theoretical challenges for studying SCEs in organizations (conceptualizing organizations as units, underappreciating meaning-making and methodological triangulation, and examining contagion in organizational networks in an age of digitalization) and developing recommendations for overcoming them.     

Mobility at the margins: The facilitating and risk-reducing role of clustered migration in migration for begging between Romania and Norway

This article describes the social and economic organization of migration for begging from Romania to Norway. Drawing on a survey among homeless Romanians in Oslo and qualitative interviews conducted in Norway and migrant-sending communities in Romania, we describe how migrants gain access to resources such as information, transport, places to beg and places to sleep, as well as social and emotional support when abroad. We argue that the particular, clustered structure of these migration flows makes migration available to persons who otherwise would not have opportunities to migrate, eases their adaptation in cities of destination and serves to protect the migrants from exploitation and abuse from external actors. This migration structure does, however, reflect a strong dependence on kinship networks, which may create vulnerabilities in itself.     

Planning Forward by Looking Backward: Retrospective Thinking in Strategic Decision Making*

Retrospective thinking occurs whenever one remembers something from the past, but one can also think retrospectively about hypothetical future events, by imagining that the event has already transpired and then working backward in the mind from the future toward the present. Designers, artists, planners, and other creative individuals utilize retrospective thinking when they mentally envision the object they wish to create and then thinkabout how it might be constructed. Some theorists and some previous research have suggested that forward and backward thinking are different cognitive processes, but there has been little investigation on the nature of these differences. This article examines the literature and describes a laboratory study designed to investigate retrospective thinking as a technique for increased idea generation. Subjects (n=64) were professional planners and managers with an average business experience of over 20 years. In a planning task, significantly more ideas were generated in the retrospective thinking mode than in the prospective mode, but the ideas were not found to be of greater quality. Evidence emerged that a subset of subjects were better able to make use of the retrospective technique, suggesting that selection along with training may be appropriate for the technique's mosteffective use.
