Digital citizenship? Narrative exchange and the changing terms of civic culture

This article explores the possibilities for new forms of ‘digital citizenship’ currently emerging through digitally supported processes of narrative exchange. Using Dahlgren's (Dahlgren, P. 2003. “Reconfiguring Civic Culture in the New Media Milieu.” In Media and the Restyling of Politics, edited by J. Corner, and D. Pels, 151–170. London: Sage; Dahlgren, P. 2009. Media and Political Engagement. Cambridge: Cambridge University Press.) circuit of ‘civic culture’ as a model for exploring the interlinking preconditions for new acts of citizenship, we discuss the contrasting outcomes of research at three fieldwork sites in the North of England – educational (a sixth form college), civil society (a community reporters' network) and social (a local club). Each site provided clear evidence of the elements of Dahlgren's circuit (some depending on the intensive use of digital infrastructure, others predating it), but there were also breaks in the circuit that constrained its effectiveness. A crucial factor in each case for building a lasting circuit of civic culture (and an effective base for new forms of digital citizenship) is the role that digital infrastructure can play in extending the scale of interactions beyond the purely local.     

Change over Tenure: Voting, Variance, and Decision Making on the U.S. Courts of Appeals

Existing scholarship on the voting behavior of U.S. Courts of Appeals judges finds that their decisions are best understood as a function of law, policy preferences, and factors relating to the institutional context of the circuit court. What previous studies have failed to consider, however, is that the ability to predict circuit judge decisions can vary in substantively important ways and that judges, in different stages of their careers, may behave distinctively. This article develops a theoretical framework which conceptualizes career stage to account for variability in voting by circuit judges and tests hypotheses by modeling the error variance in a vote choice model. The findings indicate that judges are more predictable in their voting during their early and late career stages. Case characteristics and institutional features of the circuit also affect voting consistency.     

The Etiology of the Occurrence of En Banc Review in the U.S. Court of Appeals

The U.S. Courts of Appeals, working principally through three-judge panels, constitute important final arbiters of the meaning of the federal constitution, laws, and regulations and, hence, significant policymakers within the federal system. En banc rehearing—reconsideration of the decision of a three-judge panel by the full complement of judges appointed to the circuit—is an institutional device that ensures circuit decisions are in line with the established preferences of the circuit. The use of en banc varies in frequency across circuits and within circuits over time. Drawing on legal, attitudinal, and strategic perspectives of judicial behavior, we develop and test a set of integrated expectations regarding the causes of this variation. Our analysis finds support for the operation of all three models and suggests that the influence of ideology on the use of en banc in the recent era is not unique but part of a long-standing pattern .     

Service Provision for the Global Economy: The Evolving Indian Experience

Since 1995, the offshoring of services to India has rapidly evolved from a curiosity only studied by a few scholars to a phenomenon portending a major shift in the geography of global economic activity. The article examines the evolution of Indian global services provision quantitatively and qualitatively through the use of four case studies. The first case study examines the challenge that the Indian information technology systems integrators (ITSIs) pose to the formerly larger—but now roughly comparable in terms of employment—incumbent developed-nation ITSIs. Because IT systems have become central to nearly every enterprise, the second case study illustrates the wide variety of enterprises that now have significant Indian offshore operations. The third case study describes the rapid growth of offshore integrated circuit design in India, a nation with now commercial-scale integrated circuit production. The final case study describes the emergence of high-opportunity entrepreneurial startups in India and the increasing number of Silicon Valley startups that very early in their lives or even as part of their business model have significant operations in India. The concluding discussion situates India within the global economy and speculates upon its future evolution.     

The relationship between the Financial and industrial sector in the U. K. economy

The article attempts to specify the relationship between industrial and commercial activity and the financial system within the UK economy. It does this in two ways. In the first place through a discussion of the different forms and circuits of capital which designate of the important relationships and categories integrating the financial and the industrial sectors. Secondly it assesses the specific form of the circuit of finance capital within the UK economic formation and points to some of the implications of this for the proposals to take into public ownership the Commercial Banks and Insurance Companies.     

'It's the romance,not the finance,that makes the business worth pursuing': disclosing a new market culture

This paper argues that the new economy was a rhetorical fabrication, which, through the ability of stakeholders like the cultural circuit of capital, was able to define what the facts consisted of and to train up bodies that bent to those facts. This fabrication could therefore produce regularities in the world. In the first instance, the chief beneficiary was the financial sector, which was able to use the new economy rhetoric to engineer a financial bubble. But, even after the inevitable financial crash, the new economy has left a legacy which should not be scoffed at.     

Courting the President: How Circuit Court Judges Alter Their Behavior for Promotion to the Supreme Court

We examine whether circuit court judges sacrifice policy purity for career goals. We compare the behavior of contender judges–those most likely to be elevated to the Supreme Court–during vacancy periods with their behavior outside vacancy periods. We also examine the behavior of noncontender judges during those same times. The data show that during vacancy periods, contender judges are more likely to vote consistently with the president's preferences, to rule in favor of the United States, and to write dissenting opinions. Noncontender judges fail to evidence such behavior. These findings provide empirical support for the argument that federal judges adapt their behavior to specific audiences, and provide new avenues for research into judges' goals and the role of audiences in judicial decision making.

Word and Deed: A Deweyan Integration of Deliberative and Participatory Democracy

This article draws on the political philosophy of John Dewey as one way to re-think the relationship between deliberative and participatory democracy. Rather than focusing on differences, Dewey's ideal of democracy allows us to bridge these two theories while still being attentive to the tensions between them. In particular, Dewey helps us conceptualize deliberative and participatory practices as distinctive yet complementary phases within a larger circuit of cooperative inquiry. To illustrate the argument, a case study of one democratic experiment that effectively combined different forms of practice is presented. In doing so, it is contended that we might be able to recover and incorporate some of the more radical features of participatory democracy into deliberative practices. Participatory theory's focus on political action and structural inequality, in addition to deliberation, as essential to citizen-centered democratic practice is specifically emphasized.     

A structural equation modeling analysis of marital bullying scale

Bullying has received increasing research interest, whether bullying among students in schools and universities, or bullying among employees. There is still no accordance regarding to bullying between the couple. This study aimed to investigate the construct validity and psychometric properties of the marital bullying scale with advanced statistical procedure, structural equation modeling, and exploratory factor analysis. The researchers prepared the marriage bullying scale consisting of 25 self‐report items and applied it in a random sample consisting of (760) married individual, and then, the researchers extracted the psychometric characteristics of this scale. The finding indicated that the scale has psychometric properties with a high validity and reliability. In order to ensure the validity of the structure of this scale, the researchers developed a measurement model for marital bullying. The results of the exploratory factor analysis pointed to the saturation of the items of the scale (25) on five factors and accounted for 80.815% of the total variance of the scale. The first factor was verbal bullying that accounted for 37.658%, the second factor was physical bullying that accounted for 16. 249 %, the third factor was psychological bullying that accounted for 12.850 %, the fourth factor was social bullying that accounted for 8.584 %, and the fifth factor was family bullying that accounted for (5.475 %) of the total variance of marital bullying. And then by using confirmatory factor analysis, results showed that the structure of the proposed measurement model of marital bullying has good fitness with the data collected from the sample of the study, which enhances confidence in the ability of the scale to assess marital bullying. The findings shed new light on the underlying theory behind marital bullying and proved the usefulness of structural equation modeling framework in scale development.
