Who cares? Toward an integrated theory of volunteer work

Abstract: The authors construct an integrated theory of formal and informal volunteer work based on the premises that volunteer work is (1) productive work that requires human capital, (2) collective behavior that requires social capital, and (3) ethically guided work that requires cultural capital. Using education, income and functional health to measure human capital, number of children in the household and informal social interaction to measure social capital, and religiosity to measure cultural capital, they estimate a model in which formal volunteering and informal helping are reciprocally related but connected in different ways to different forms of capital. Using two-wave data from the Americans' Changing Lives panel study, they find that formal volunteering is positively related to human capital, number of children in the household, informal social interaction and religiosity. Informal helping, such as helping a neighbor, is primarily determined by gender, age and health. Estimation of reciprocal effects reveals that formal volunteering has a positive effect on helping, but helping does not affect formal volunteering

Framing Processes and Social Movements: An Overview and Assessment

Abstract: ■ Abstract The recent proliferation of scholarship on collective action frames and framing processes in relation to social movements indicates that framing processes have come to be regarded, alongside resource mobilization and political opportunity processes, as a central dynamic in understanding the character and course of social movements. This review examines the analytic utility of the framing literature for un- derstanding social movement dynamics. We first review how collective action frames have been conceptualized, including their characteristic and variable features. We then examine the literature related to framing dynamics and processes. Next we review the literature regarding various contextual factors that constrain and facilitate framing processes. We conclude with an elaboration of the consequences of framing processes for other movement processes and outcomes. We seek throughout to provide clarifi- cation of the linkages between framing concepts/processes and other conceptual and theoretical formulations relevant to social movements, such as schemas and ideology.

Resource Mobilization and Social Movements: A Partial Theory

Abstract: Past analysis of social movements and social movement organizations has normally assumed a close link between the frustrations or grievances of a collectivity of actors and the growth and decline of movement activity. Questioning the theoretical centrality of this assumption directs social movement analysis away from its heavy emphasis upon the social psychology of social movement participants; it can then be more easily integrated with structural theories of social process. This essay presents a set of concepts and related propositions drawn from a resource mobilization perspective. It emphasizes the variety and sources of resources; the relationship of social movements to the media, authorities, and other parties; and the interaction among movement organizations. Propositions are developed to explain social movement activity at several levels of inclusiveness-the social movement sector, the social movement industry, and social movement organization.

Bowling alone: The collapse and revival of American community

Abstract: The present historical moment may seem a particularly inopportune time to review Bowling Alone, Robert Putnam's latest exploration of civic decline in America. After all, the outpouring of volunteerism, solidarity, patriotism, and self-sacrifice displayed by Americans in the wake of the September 11 terrorist attacks appears to fly in the face of Putnam's central argument: that \"social capital\" -defined as \"social networks and the norms of reciprocity and trustworthiness that arise from them\" (p. 19)'has declined to dangerously low levels in America over the last three decades. However, Putnam is not fazed in the least by the recent effusion of solidarity. Quite the contrary, he sees in it the potential to \"reverse what has been a 30to 40-year steady decline in most measures of connectedness or community.\"' As an example of how the current \"war on terrorism\" could generate a durable civic renewal, Putnam points to the burst in civic practices that occurred during and after World War II, which he says \"permanently marked\" the generation that lived through it and had a \"terrific effect on American public life over the last half-century.\" 3 If Americans can follow this example and channel their current civic
