Enduring Legacy? Charles Tilly and Durable Inequality

This article assesses Charles Tilly’s Durable Inequality and traces its influence. In writing Durable Inequality, Tilly sought to shift the research agenda of stratification scholars. But the book’s initial impact was disappointing. In recent years, however, its influence has grown, suggesting a more enduring legacy

Thermodynamics of Heat Shock Response

Production of heat shock proteins are induced when a living cell is exposed to a rise in temperature. The heat shock response of protein DnaK synthesis in E.coli for temperature shifts from temperature T to T plus 7 degrees, respectively to T minus 7 degrees is measured as function of the initial temperature T. We observe a reversed heat shock at low T. The magnitude of the shock increases when one increase the distance to the temperature $T_0 \approx 23^o$, thereby mimicking the non monotous stability of proteins at low temperature. Further we found that the variation of the heat shock with T quantitatively follows the thermodynamic stability of proteins with temperature. This suggest that stability related to hot as well as cold unfolding of proteins is directly implemented in the biological control of protein folding. We demonstrate that such an implementation is possible in a minimalistic chemical network.Comment: To be published in Physical Review Letter

Equation of Motion for a Spin Vortex and Geometric Force

The Hamiltonian equation of motion is studied for a vortex occuring in 2-dimensional Heisenberg ferromagnet of anisotropic type by starting with the effective action for the spin field formulated by the Bloch (or spin) coherent state. The resultant equation shows the existence of a geometric force that is analogous to the so-called Magnus force in superfluid. This specific force plays a significant role for a quantum dynamics for a single vortex, e.g, the determination of the bound state of the vortex trapped by a pinning force arising from the interaction of the vortex with an impurity.Comment: 13 pages, plain te

Political Regimes and Sovereign Credit Risk in Europe, 1750-1913

This article uses a new panel data set to perform a statistical analysis of political regimes and sovereign credit risk in Europe from 1750 to 1913. Old Regime polities typically suffered from fiscal fragmentation and absolutist rule. By the start of World War I, however, many such countries had centralized institutions and limited government. Panel regressions indicate that centralized and?or limited regimes were associated with significant improvements in credit risk relative to fragmented and absolutist ones. Structural break tests also reveal close relationships between major turning points in yield series and political transformations

TNCs & Congestion

From the executive summary: This document: Identifies common measures of roadway congestion; Discusses factors that contribute to roadway to congestion; and Quantifies the relative contributions of different factors, including population, employment, road network changes and TNCs, to observed changes in congestion in San Francisco between 2010 and 2016, by location and time of day. The report utilizes a unique TNC trip dataset provided to the Transportation Authority by researchers from Northeastern University in late 2016, as well as INRIX data, a commercial dataset which combines several real-time GPS monitoring sources with data from highway performance monitoring systems. These data are augmented with information on network changes, population changes, and employment changes provided by local and regional planning agencies, which are used as input to the Transportation Authority’s activity-based regional travel demand model SF-CHAMP

Tilly's Technical Accounts and Standard Stories Explored in Financial Markets:The Case of the Istanbul Stock Exchange

In this article, I follow the lead opened up by Tilly (1999, 2002) who was interested in people's storytelling. I do so by looking at sense-making and the legitimacy narratives of market actors in the Istanbul Stock Exchange. Tilly (2006, 2008) himself walked the narrative path and investigated Why and how people give reasons and how people attribute Credit and Blame to other's actions. These books provide insights into people's storytelling in the everyday situations of the home, courtrooms, hospitals, and so on. Nevertheless, Tilly's faith in the prevalence of technical accounts as modes of explanation in intra and inter organisational settings, and superior stories as mode of communication between expert givers and non-specialized receivers, seems to ignore informational uncertainties, intra and inter organisational hierarchies and conflicts pertinent to organisations. It is these factors that push standard stories (Tilly, 1999) into the forefront at the expense of technical stories within the story exchanges of market actors. I demonstrate this by presenting a sample of story exchanges from the Istanbul Stock Exchange under situations of informational uncertainties and organisational conflicts

Understanding governmental activism

This article seeks to understand an understudied phenomenon: governmental players joining forces with non-governmental players in contentious actions against policies they want to prevent or redress. This behaviour, which we call ‘governmental activism’, problematizes important assumptions in the social movement literature on state–SMO dichotomies and on seeing ‘the state’ as a homogeneous and unified actor that solely provides the context for SMO activities. Governmental activism also problematizes assumptions on cooperation and ‘new’ modes of coordination in the governance literature. To understand governmental activism, we build on the strategic interaction perspective from social movement studies and on third-phase institutionalism from political science. In our analysis, we show the particulars of governmental activism. Our arguments are illustrated by empirical material on a case of municipal amalgamation in the Netherlands
