Political Fact-Checking on Twitter: When Do Corrections Have an Effect?

Research suggests that fact checking corrections have only a limited impact on the spread of false rumors. However, research has not considered that fact-checking may be socially contingent, meaning there are social contexts in which truth may be more or less preferred. In particular, we argue that strong social connections between fact-checkers and rumor spreaders encourage the latter to prefer sharing accurate information, making them more likely to accept corrections. We test this argument on real corrections made on Twitter between Janurary 2012 and April, 2014. As hypothesized, we find that individuals who follow and are followed by the people who correct them are significantly more likely to accept the correction than individuals confronted by strangers. We then replicate our findings on new data drawn from November 2015 to February, 2016. These findings suggest that the underlying social structure is an important factor in the correction of misinformation.     

Migration and the formation of transnational economic networks between Africa and Turkey: the socio-economic establishment of migrants in situ and in mobility

Turkey is often perceived as a transit place for migrants and refugees from the African continent. While many indeed continue to other countries and the country still precludes official local integration, the past decade has witnessed a growing number of African migrants settling in Istanbul. This article draws attention to the opportunity structures that enable this type of settlement. The article presents the argument that it is the presence of small-scale transnationally embedded traders from the same countries that enable the socio-economic stability of their co-nationals both locally as well as transnationally. The concept that is able to account for this development is establishment in situ and establishment in mobility, which is seen as exactly the definitional barrier between transit and settlement.     

The Origins of the European Coalition for Vision: Exploring the Formation of a Network

Despite growing interest in EU-level transnational networks, there is little understanding about how these form. This article investigates the formation of one network—the European Coalition for Vision (ECV). Using document analysis of 100 email exchanges, 12 semi-structured interviews, and observation of 5 ECV meetings, it identifies environmental and organizational triggers, most important to the creation of the ECV. Findings show that while environmental triggers played a role in ECV formation, organizational triggers were crucial. In particular, the presence of network leaders, a network entrepreneur and a network mentor were vital for the successful creation of the network.     

Flying bananas: small producer tactics and the (un)making of Philippine banana export chains

Global production network (GPN) analysts argue that workers actively contribute to the shaping of GPNs through different forms of agency. In this contribution I extend this argument to the tactical agency of small producers. By focusing on the phenomenon of side-selling among Filipino banana contract farmers, I show that these tactics have contributed to the emergence of alternative trade networks that undermined traditional lead firm behaviour and inspired new struggles over chain governance. However, as a diverse and ambiguous group of growers engages in this tactical agency, predominantly as small capital, they also contribute to the continuation of broader dynamics of capital accumulation and labour exploitation.     

Transnational policy networks in the migration field: a challenge for the European Union

The migration policy field is a multilayered and fragmented area still lacking a strong global and European regime. Nonetheless, different initiatives and fora have been promoted in the last decade to increase the international dialogue on migration, with the active participation of non-state actors, and particularly civil society organisations (CSOs). The article reviews selected initiatives undertaken at the UN and European level, whereby institutional representatives engage with CSOs in furthering migration policies. These initiatives and platforms may constitute transnational policy networks (TPNs). It explores signals towards the consolidation of more structured and ‘hard’ forms of participatory policy-making on migration issues, as well as obstacles present in this engagement dynamic. The key question addressed in this study is whether and how European institutions have engaged with the TPNs in the field of migration. The article also explores how some of the TPNs influence institutional policy-making at the EU level.     

The emergence of regulatory regionalism: transnational networks and the diffusion of regulatory agencies within regions

The regulatory regionalism approach has increasingly claimed that a new mode of regional governance is emerging globally. Regional policy regimes, developed in broad social and economic territorial areas, affect the internal transformation of the state. The authors plan to provide comprehensive empirical evidence about the emergence of worldwide regulatory regionalism by identifying how regulatory agencies have diffused very successfully within the regional level in recent decades. The paper aims to identify, using an original methodological design, the ways in which such diffusion of agencies occurred, as this may have theoretical relevance for the study of regulatory regionalism. The authors' hypothesis suggests that transnational political interactions in each regional cluster triggered agency diffusion, contributing to the development of the regulatory state within the countries of each region. To test this hypothesis, the authors employed a data set of regulatory agencies including the OECD (Organisation for Economic Co-operation and Development), and most Asian and Latin American countries (+59) from 1950 to 2007, for 15 sectors related to finance, risks, utility and competition. Bayesian data analysis was used to estimate the parameters of interest.     

School punishment and interpersonal exclusion: Rejection,withdrawal, and separation from friends

School suspension is a common form of punishment in the United States that is disproportionately concentrated among racial minority and disadvantaged youth. In labeling theories, the implication is that such stigmatized sanctions may lead to interpersonal exclusion from normative others and to greater involvement with antisocial peers. I test this implication in the context of rural schools by 1) examining the association between suspension and discontinuity in same-grade friendship ties, focusing on three mechanisms implied in labeling theories: rejection, withdrawal, and physical separation; 2) testing the association between suspension and increased involvement with antisocial peers; and (3) assessing whether these associations are stronger in smaller schools. Consistent with labeling theories, I find suspension associated with greater discontinuity in friendship ties, based on changes in the respondents’ friendship preferences and self-reports of their peers. My findings are also consistent with changes in perceptual measures of exclusion. Additionally, I find suspension associated with greater involvement with substance-using peers. Some but not all of these associations are stronger in smaller rural schools. Given the disproportionate distribution of suspension, my findings indicate that an excessive reliance on this exclusionary form of punishment may foster inequality among these youth.
