Social media and Russian territorial irredentism: some facts and a conjecture

ABSTRACT

After Kremlin policymakers decided to incorporate the territory of Crimea into Russia, updates on public attitudes in Russian-speaking communities elsewhere in Ukraine would have been in high demand. Because social media users produce content in order to communicate ideas to their social networks, online political discourse can provide important clues about the political dispositions of communities. We map the evolution of Russian-speakers’ attitudes, expressed on social media, across the course of the conflict as Russian analysts might have observed them at the time. Results suggest that the Russian-Ukrainian interstate border only moved as far as their military could have advanced while incurring no occupation costs – Crimea, and no further.     

Conclusion: International Political Economy—The Reverse Salient of Innovation Theory

This conclusion attempts to answer three sets of questions regarding our experiment in cross-field collaboration: What did we find and were these findings cohesive? What did our findings add to the debate? What are the implications of our findings, and, more importantly, what's next? It suggests that politics have become a "reverse salient" in innovation theory. Specifically, innovation scholars have yet to devise a theory that fully incorporates distributive politics and their security and competitiveness implications into a general explanation of technological change. This gap is holding back progress in fields that depend on innovation as an explanatory variable. It should therefore be made a priority for innovation scholars across the social sciences.     

Drug and alcohol use as determinants of New York City homicide trends from 1990 to 1998

In this population-level study, we analyzed how well changes in drug and alcohol use among homicide victims explained declining homicide rates in New York City between 1990 and 1998. Victim demographics, cause of death, and toxicology were obtained for all homicide (N = 12573) and accidental death victims (N = 6351) between 1990 and 1998 from the Office of the Chief Medical Examiner of New York (OCME). The proportion of homicide and accident decedents positive for cocaine fell between 1990 and 1998 (13% and 9% respectively); the proportion of homicide and accident decedents positive for opiates and/or alcohol did not change significantly. Changing patterns of drug and alcohol use by homicide victims were comparable to changing patterns of drug and alcohol use in accident victims, suggesting that changes in drug and alcohol use among homicide victims between 1990 and 1998 cannot solely explain the decline in NYC homicide rates.     

Selection and Incentives in the Electoral Security‐Constituency Communication Relationship

The relative importance of selection and incentives is essential for understanding how elections structure politicians’ behavior. I investigate the relative magnitudes of these two effects in the context of US House members’ constituency communication. Consistent with previous research, I find that there is a negative cross‐sectional relationship between electoral security and the intensity of constituency communication. The negative relationship holds in a panel‐data setting where only within‐legislator variation in electoral security is used to identify the effect of electoral security on legislator behavior. Due to the likely presence of myopic voters, the impact of electoral security increases as the election approaches. Point estimates suggest that the total effect is almost entirely driven by incentives, and I am able to reject the hypothesis that the incentive effect is zero at conventional levels of statistical significance.
