■ 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.

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.

Resource Mobilization and Social Movements: A Partial Theory

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

An important advancement in structural engineering in recent years has been the development of performance-based design (PBD). However, its application to cold-formed steel framed buildings remains largely unexplored. This paper presents the assessment of the bracing capacity of cold-formed steel stud bracing wall panels using a direct-displacement based design (DDBD) approach. The fundamentals of DDBD using equivalent damping, and inelastic displacement response spectra approaches are presented. These wall parameters needed for each approach are evaluated from experimental load–deflection response behaviour under quasi-static cyclic loading. Results obtained from the DDBD approach are compared with results from conventional non-linear time history analyses (NLTHA) to confirm the validity of the adopted approach. It is found that results estimated from DDBD method using inelastic displacement response spectra approach correlated much better with NLTHA results than the equivalent damping method.

Given a set S of sites and a set O of weighted objects, an optimal location query finds the location(s) where introducing a new site maximizes the total weight of the objects that are closer to the new site than to any other site. With such a query, for instance, a franchise corporation (e.g., McDonald's) can find a location to open a new store such that the number of potential store customers (i.e., people living close to the store) is maximized. Optimal location queries are computationally complex to compute and require efficient solutions that scale with large datasets. Previously, two specific approaches have been proposed for efficient computation of optimal location queries. However, they both assume p-norm distance (namely, L1 and L2/Euclidean); hence, they are not applicable where sites and objects are located on spatial networks. In this article, we focus on optimal network location (ONL) queries, i.e., optimal location queries in which objects and sites reside on a spatial network. We introduce two complementary approaches, namely EONL (short for Expansion-based ONL) and BONL (short for Bound-based ONL), which enable efficient computation of ONL queries with datasets of uniform and skewed distributions, respectively. Moreover, with an extensive experimental study we verify and compare the efficiency of our proposed approaches with real world datasets, and we demonstrate the importance of considering network distance (rather than p-norm distance) with ONL queries.

The detection of concealed weapons is one of the biggest challenges facing the security community. It has been shown that each weapon can have a unique fingerprint, which is an electromagnetic signal determined by its size, shape, and physical composition. Extracting the signature of each weapon is one of the major tasks of any detection system. This paper addresses the issue of identifying conductive objects based on their response to electromagnetic fields. A system developed at Newcastle University using a walk-through metal detector with a giant magneto-resistive sensor array to measure the spatial magnetic field is used in the study. Threat and non-threat objects have been tested. Image visualization and feature extraction of the electromagnetic field were carried out. Classification was performed using cross correlation. Promising results indicating the feasibility of using electromagnetic imaging to identify objects have been found.
