We estimated ideological preferences of 3.8 million Twitter users and, using a data set of nearly 150 million tweets concerning 12 political and nonpolitical issues, explored whether online communication resembles an “echo chamber” (as a result of selective exposure and ideological segregation) or a “national conversation.” We observed that information was exchanged primarily among individuals ...

Guaranteed Annuity Options (GAOs) are options available to holders of certain pension policies. Under these contracts, policyholders contribute premiums into a fund managed by the insurer. At retirement, the policyholders buy life annuities at a guaranteed rate provided by the original insurer, or annuitize with another insurer. If the guaranteed annuity rates are better than the prevailing rat...

This article assesses insurance uptake in three community-based health insurance (CBHI) schemes located in rural parts of two of India's poorest states and offered through women's self-help groups (SHGs). We examine what drives uptake, the degree of inclusive practices of the schemes and the influence of health status on enrolment. The most important finding is that a household's socio-economic...

The flavor du jour in discussions of Islamic terrorism features a de-emphasis on the ideological component, drawing instead upon epidemiological and criminological concepts; approaching Mexican drug gangs and Islamic extremists as being more similar than they are different. This aids a network scrutiny and suggests buy-out rather than ideological deradicalization. Such new abandonments of the i...

This work explores the utility of sentiment and arguing opinions for classifying stances in ideological debates. In order to capture arguing opinions in ideological stance taking, we construct an arguing lexicon automatically from a manually annotated corpus. We build supervised systems employing sentiment and arguing opinions and their targets as features. Our systems perform substantially bet...

Ideology and its function in digital games has received considerable scholarly interest in the field of game studies, though only more recently has criticism interested itself with the ideological implications of game mechanics in conjunction with a game's representational content. Relying on an Althusserian definition of ideology, this paper builds upon the existing methodology of procedural r...

Four studies investigated a goal regulation view of anxious uncertainty threat (Gray & McNaughton, 2000) and ideological defense. Participants (N = 444) were randomly assigned to have achievement or relationship goals implicitly primed. The implicit goal primes were followed by randomly assigned achievement or relationship threats that have reliably caused generalized, reactive approach motivat...

The emergence of politically driven divisions in online discussion networks has attracted a wealth of literature, but also one which has thus far been largely limited to single country studies. Hence whilst there is good evidence that these networks do divide and fragment into what are often described as “echo chambers”, we know little about the factors which might explain this division or make...
