Research dealing with the nexus of collective action, political participation, and digital media confronts three challenges: conceptualizing digital media as an influence on human behavior, finding common ground among new theories, and connecting together individual-level models with structural-level theories. This article addresses these challenges as a theoretical undertaking. It argues that the digital media environment should be understood as a change in the context for action rather than as an individual-level variable, and that this changed context is relevant to behavior because it expands opportunities for action. This expansion involves a range of structural possibilities for viable collective action that entail at least three paths: organizational prompts, social prompts, and self-initiation. There are theoretical reasons to expect that individual-level attributes including age, education, ideology, and personality may differentially affect people’s susceptibility to these prompts. Future research may profit from refinements to behavioral models that account for possible differences across structurally different prompts for action.  相似文献

The European Union (EU) and Australia have embarked officially on a free trade agreement (FTA) negotiation process, a procedure expected to last no less than 5 years. Public pronouncements from both sides which announced the beginning of the process of negotiating an FTA marked a significant departure from the well-known tensions and difficulties which date back to the late 1950s. British entry into the then European Economic Community in 1973 meant that it had to align its trade policies with the much contested European Common Agricultural Policy (CAP). This had been implemented in the late 1960s and provided limitless reasons for antagonism between Australia and the EU. Yet, over time, the trade agenda changed for both sides with new actors and new agreements, and some of the previous machinery no longer providing the liberalisation of trade as intended. Both the EU and Australia have moved on—some of this change due to new political actors and new economic realities. Despite the tortured history between them, and mindful that some might be sceptical about this change of heart, real politik often imposes its own political will and the new needs may well be in sharp contrast to the past relationships. The prospect of an FTA shows how the trappings of history might be side stepped by a stronger, almost opportunistic, sense of economic benefits however small they might appear.  相似文献

Sunshine laws establishing government transparency are ubiquitous in the United States; however, the intended degree of openness is often unclear or unrealized. Although researchers have identified characteristics of government organizations or officials that affect the fulfillment of public records requests, they have not considered the influence that government organizations have on one another. This picture of independently acting organizations does not accord with the literature on diffusion in public policy and administration. This article presents a field experiment testing whether a county government's fulfillment of a public records request is influenced by the knowledge that its peers have already complied. The authors propose that knowledge of peer compliance should induce competitive pressures to comply and resolve legal ambiguity in favor of compliance. Findings indicate peer conformity affects both in the time to initial response and in the rate of complete request fulfillment.  相似文献

This article seeks to accomplish four tasks. It explores the historical relationship between the financing instruments that dominated different phases of the evolution of the UN development system and the understanding of the concept of multilateralism. Bearing in mind this historical context, it seeks to analyse the defining characteristics of multilateral finance in the context of the UN, in particular the characteristics that make a financial instrument more or less multilateral. It then explores a number of new financial instruments and their possible impact on the future shape multilateralism takes in the UN system. The article concludes with some thoughts on financing for a new multilateralism. In order to go beyond the core/non-core stalemate, it is necessary to develop a new variable geometry based on function, which brings into play assessed, negotiated pledges, voluntary core and non-core instruments.  相似文献

ABSTRACT

This article reports the findings of field research into the vernacular understanding of security in South West Cameroon. It was found that security significantly contested; it is both objective and subjective; it is communal, whilst at the same time requiring individual l responsibility of personal security; it favours certainty and stability; it draws on a multiplicity of providers, and it goes beyond traditional conceptualisations. The findings make it clear that there are wide divergences between the typical state and donor driven security reform programmes, and people’s perceived security needs. The definition of security is challenged by popular understandings. In addition, though not rejecting the need for state security, it is evident that many more actors are engaged in security provision and personal safety than state actors, and that these actors need to be accounted for in reform programmes. Conclusion draw out advantages of the vernacular approach in security reform programmes.  相似文献

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ18O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.  相似文献
