Double-Edged Rituals and the Symbolic Resources of Collective Action: Political Commemorations and the Mobilization of Protest in 1989

The year 1989 was rife with resonant political anniversaries in both Eastern Europe and China ̶ as well as being the two-hundredth anniversary of France’s first great democratic revolution. Democracy and the future of socialism were on many peoples’ minds. Communist elites hoped to use these anniversaries as opportunities to celebrate the triumphs of the last forty years, but dissidents found these anniversaries even more auspicious as occasions to condemn “really existing” socialism. As a result, popular revolts erupted from Beijing to Berlin

Causes and consequences of the protestant reformation

The Protestant Reformation is one of the defining events of the last millennium. Nearly 500 years after the Reformation, its causes and consequences have seen a renewed interest in the social sciences. Research in economics, sociology, and political science increasingly uses detailed individual-level, city-level, and regional-level data to identify drivers of the adoption of the Reformation, its diffusion pattern, and its socioeconomic consequences. We take stock of this research, pointing out what we know and what we do not know and suggesting the most promising areas for future research

Competing Social Influence in Contested Diffusion: Luther, Erasmus and the Spread of the Protestant Reformation

The spread of radical institutional change does not often result from one-sided pro-innovation influence; countervailing influence networks in support of the status quo can suppress adoption. We develop a model of multiple and competing network diffusion. To apply the contested-diffusion model to real data, we look at the contest between Martin Luther and Desiderius Erasmus, the two most influential intellectuals of early 16th-century Central Europe. Whereas Luther championed a radical reform of the Western Church that broke with Rome, Erasmus opposed him, stressing the unity of the Church. In the early phase of the Reformation, these two figures utilized influence networks of followers, affecting which cities in the Holy Roman Empire adopted reform. Using newly digitalized data on both leaders’ correspondence networks, their travels, the dispersion of their followers, and parallel processes of exchange among places through trade routes, we employ econometric tests and network simulations to test our theoretical model. We find that Luther’s network is strongly associated with the spread of the Reformation and that Erasmus’s network is associated with the stifling of the Reformation. This is consistent with a “fire-fighting” mechanism of contested diffusion, whereby the countervailing force suppresses innovations only after they have begun to spread

Multiplex network ties and the spatial diffusion of radical innovations : Martin Luther’s leadership in the early reformation

This article analyzes Martin Luther’s role in spreading the early Reformation, one of the most important episodes of radical institutional change in the last millennium. We argue that social relations played a key role in its diffusion because the spread of heterodox ideologies and their eventual institutionalization relied not only on private “infection” through exposure to innovation but also on active conversion and promotion of that new faith through personal ties. We conceive of that process as leader-to-follower directional influence originating with Luther and flowing to local elites through personal ties. Based on novel data on Luther’s correspondence, Luther’s visits, and student enrollments in Luther’s city of Wittenberg, we reconstruct Luther’s influence network to examine whether local connections to him increased the odds of adopting Protestantism. Using regression analyses and simulations based on empirical network data, we find that the combination of personal/relational diffusion via Luther’s multiplex ties and spatial/structural diffusion via trade routes fostered cities’ adoption of the Reformation, making possible Protestantism’s early breakthrough from a regional movement to a general rebellion against the Roman Catholic Church

Church and State in historical political economy

Over many centuries, church and state have grown together, and apart. Sometimes linked like Siamese twins, sometimes in conflict with each other. This chapter discusses the major themes in the literature on church and state, some of the findings in the political economy of religion, and evaluates emerging directions in research on church-state relations

Of “raisins” and “yeast”: mobilisation and framing in the East German revolution of 1989

There is no shortage of literature on the social movements that arose in East Germany in 1989. Numerous studies have shed light upon the nature, scale and dynamics of the uprising of that year. But on certain issues questions remain. No consensus exists, for example, on the relationship between the “civic groups” (New Forum, Democratic Awakening, etc.) and the street protests of the autumn of 1989. Were these simply two facets of a single movement? Or are they better characterised as two distinct streams within the same movement delta? Did the street protests push the civic movement activists into the limelight? Or is it more accurate to say, with Reinfried Musch, that “the civic movement brought the people onto the streets”?1 This paper considers two contrasting interpretations of these issues, and finds both wanting. An alternative interpretation is offered, one that draws upon Marc Steinberg's “dialogical” development of frame theory

Roads & SDGs, tradeoffs and synergies: learning from Brazil's Amazon in distinguishing frontiers

To inform the search for SDG synergies in infrastructure provision, and to reduce SDG tradeoffs, the authors show that road impacts on Brazilian Amazon forests have varied significantly across settings. Forest loss varied predictably with prior development – both prior roads and prior deforestation – and in a spatial pattern suggesting a synergy between forests and urban growth in such frontiers. Examining multiple roads investments, the authors estimate impact for settings of high, medium and low prior roads and deforestation. Census-tract observations are numerous for each setting and reveal a pattern, not consistent with endogeneity, that confirms our predictions for this kind of frontier. Impacts are: low after relatively high prior development; larger for medium prior development, at the forest margin; then low again for low prior development. For the latter setting, the authors note that in such isolated areas, interactions with conservation policies influence forest impacts over time. These Amazonian results suggest 'SDG strategic' locations of infrastructure, an idea they suggest for other frontiers while highlighting differences in those frontiers and their SDG opportunities

Using Schumann Resonance Measurements for Constraining the Water Abundance on the Giant Planets - Implications for the Solar System Formation

The formation and evolution of the Solar System is closely related to the abundance of volatiles, namely water, ammonia, and methane in the protoplanetary disk. Accurate measurement of volatiles in the Solar System is therefore important to understand not only the nebular hypothesis and origin of life but also planetary cosmogony as a whole. In this work, we propose a new, remote sensing technique to infer the outer planets water content by measuring Tremendously and Extremely Low Frequency (TLF-ELF) electromagnetic wave characteristics (Schumann resonances) excited by lightning in their gaseous envelopes. Schumann resonance detection can be potentially used for constraining the uncertainty of volatiles of the giant planets, mainly Uranus and Neptune, because such TLF-ELF wave signatures are closely related to the electric conductivity profile and water content

FireDeX: a Prioritized IoT Data Exchange Middleware for Emergency Response

International audienceReal-time event detection and targeted decision making for emerging mission-critical applications, e.g. smart fire fighting, requires systems that extract and process relevant data from connected IoT devices in the environment. In this paper, we propose FireDeX, a cross-layer middleware that facilitates timely and effective exchange of data for coordinating emergency response activities. FireDeX adopts a publish-subscribe data exchange paradigm with brokers at the network edge to manage prioritized delivery of mission-critical data from IoT sources to relevant subscribers. It incorporates parameters at the application, network, and middleware layers into a data exchange service that accurately estimates end-to-end performance metrics (e.g. delays, success rates). We design an extensible queueing theoretic model that abstracts these cross-layer interactions as a network of queues, thereby making it amenable for rapid analysis. We propose novel algorithms that utilize results of this analysis to tune data exchange configurations (event priorities and dropping policies) while meeting situational awareness requirements and resource constraints. FireDeX leverages Software-Defined Networking (SDN) methodologies to enforce these configurations in the IoT network infrastructure. We evaluate its performance through simulated experiments in a smart building fire response scenario. Our results demonstrate significant improvement to mission-critical data delivery under a variety of conditions. Our application-aware prioritization algorithm improves the value of exchanged information by 36% when compared with no prioritization; the addition of our network-aware drop rate policies improves this performance by 42% over priorities only and by 94% over no prioritization
