Are legislators responsive to the priorities of the public? Research demonstrates a strong correspondence between the issues about which the public cares and the issues addressed by politicians, but conclusive evidence about who leads whom in setting the political agenda has yet to be uncovered. We answer this question with fine-grained temporal analyses of Twitter messages by legislators and the public during the 113th US Congress. After employing an unsupervised method that classifies tweets sent by legislators and citizens into topics, we use vector autoregression models to explore whose priorities more strongly predict the relationship between citizens and politicians. We find that legislators are more likely to follow, than to lead, discussion of public issues, results that hold even after controlling for the agenda-setting effects of the media. We also find, however, that legislators are more likely to be responsive to their supporters than to the general public.
This study is an exploratory analysis of enabling technologies’ influence on the trajectory of industry development using a co-evolutionary model of technology development. When combined, enabling technologies can create new technology-market industry cycles, resulting in transformative innovation. The research approach of this empirical study is to use both primary and secondary data to create a history of the robotics industry and to explore the pre and post changes in the industry from the inclusion of enabling technologies over multiple generations. We propose a new model for understanding the theoretical and practical study of technology development through the lens of enabling technologies and their development and maturity cycles.
ON THE OCCASION of Theodor Fontane's two hundredth birthday, his reaction to an earlier birthday yields food for thought. Fontane describes his seventieth birthday celebration to Heinrich Jacobi on January 23, 1890:
Man hat mich kolossal gefeiert und—auch wieder gar nicht. Das moderne Berlin hat einen Götzen aus mir gemacht, aber das alte Preußen, das ich, durch mehr als 40 Jahre hin, in Kriegsbüchern, Biographien, Land- und Leute-Schilderungen und volkstümlichen Gedichten verherrlicht habe, dies “alte Preußen” hat sich kaum gerührt …
[I was celebrated colossally and—again not at all. Modern Berlin made an idol out of me, but old Prussia, which I had glorified throughout more than forty years—in war reports, biographies, descriptions of country and people, and in popular poems—this “old Prussia” hardly stirred …]
The disparity in perception between modern Berlin and old Prussia clearly troubles Fontane; one senses that, at some level, he longs to be acknowledged by traditional Prussia, much as he may despise it, and that his image of himself as a writer does not coincide with the image that the literary world has of him. This tension, even contradiction, mirrors the enigmatic reception of Fontane in subsequent generations and particularly in the English-speaking world. Fontane is sometimes an advocate for the declining landed nobility of Prussia, sometimes the pioneer of the modernist metropolis, the champion of rural Prussia and Brandenburg but also of cosmopolitan London and the world at large. Is he regressive or progressive, an advocate of provincialism or cosmopolitanism, a traditionalist or a modernist? Fontane's staying power comes in part from his resistance to easy classification according to such binaries. He still speaks to us today because he sustains a productive tension between both the modernist idol and the compassionate, albeit ironic, chronicler of “old Prussia.”
With this volume celebrating Fontane's two hundredth birthday, we engage the tension between the modern and the traditional, the contemporary and the historical in Fontane by offering a range of contributions from the world of English-language Fontane scholarship in the twenty-first century. Balancing the competing demands of fidelity to the author's history and literary production in the nineteenth century with the interests of our own era requires recognizing both the striking similarities and the stark differences between the late-nineteenth and the early-twenty-first centuries.
