Vehicle Retirement

Vehicle retirement programs have become popular tools of public policy for reducing pollution. The efficacy of these programs is difficult to measure, as it is difficult to tell how much a vehicle would have polluted otherwise. I estimate that counterfactual using data from a long-running local program in California. I utilize the universe of emissions inspections from the California Smog Check Program to construct vehicle usage histories of retired cars and similar vehicles which did not retire early. I find that the program's cost-effectiveness steadily declined over time because of the depreciation of the vehicle fleet, while adverse selection remained a problem throughout.

Although congressional investigations have provided some of the most dramatic moments in American political history, they have often been dismissed as mere political theater. But these investigations are far more than grandstanding. This book shows that congressional investigations are a powerful tool for members of Congress to counter presidential aggrandizement. By shining a light on alleged executive wrongdoing, investigations can exert significant pressure on the president and materially affect policy outcomes. This book constructs the most comprehensive overview of congressional investigative oversight to date, analyzing nearly 13,000 days of hearings, spanning more than a century, from 1898 through 2014. The book examines the forces driving investigative power over time and across chambers, and identifies how hearings might influence the president’s strategic calculations through the erosion of the president’s public approval rating, and uncover the pathways through which investigations have shaped public policy. Put simply, by bringing significant political pressure to bear on the president, investigations often afford Congress a blunt, but effective check on presidential power—without the need to worry about veto threats or other hurdles such as Senate filibusters. In an era of intense partisan polarization and institutional dysfunction, the book delves into the dynamics of congressional investigations and how Congress leverages this tool to counterbalance presidential power.

Over Time

In this essay I examine the dispute between the German GreenParty and some of the country’s environmental nongovernmentalorganizations (NGOs) over the March 2001 renewal of rail shipmentsof highly radioactive wastes to Gorleben. My purpose indoing so is to test John Dryzek’s 1996 claim that environmentalistsought to beware of what they wish for concerning inclusion in theliberal democratic state. Inclusion on the wrong terms, arguesDryzek, may prove detrimental to the goals of greening and democratizingpublic policy because such inclusion may compromise thesurvival of a green public sphere that is vital to both. Prospects forecological democracy, understood in terms of strong ecologicalmodernization here, depend on historically conditioned relationshipsbetween the state and the environmental movement that fosterthe emergence and persistence over time of such a public sphere.

Astrophysical tests of current values for dimensionless constants known on Earth, such as the fine-structure constant, α , and proton-to-electron mass ratio, μ = m p / m e , are communicated using data from high-resolution quasar spectra in different regions or epochs of the universe. The symmetry wavelengths of [Fe II] lines from redshifted quasar spectra of J110325-264515 and their corresponding values in the laboratory were combined to find a new limit on space-time variations in the proton-to-electron mass ratio, ∆ μ / μ = ( 0.096 ± 0.182 ) × 10 − 7 . The results show how the indicated astrophysical observations can further improve the accuracy and space-time variations of physics constants.

Extensive research has identified factors influencing collective-action participation. However, less is known about how collective-action outcomes (i.e., success and failure) shape engagement in social movements over time. Using data collected before and after the 2017 marriage-equality debate in Australia, we conducted a latent profile analysis that indicated that success unified supporters of change ( n = 420), whereas failure created subgroups among opponents ( n = 419), reflecting four divergent responses: disengagement (resigned acceptors), moderate disengagement and continued investment (moderates), and renewed commitment to the cause using similar strategies (stay-the-course opponents) or new strategies (innovators). Resigned acceptors were least inclined to act following failure, whereas innovators were generally more likely to engage in conventional action and justify using radical action relative to the other profiles. These divergent reactions were predicted by differing baseline levels of social identification, group efficacy, and anger. Collective-action outcomes dynamically shape participation in social movements; this is an important direction for future research.

We examine the effects of socio-environmental change on personality in Mali in three ways, using data from a longitudinal two-wave (1994, 2004) survey conducted in rural Mali. Firstly, we compare the between-wave personality stability of Anxiety, Self-confidence, Mastery/Fatalism, and Authoritarianism with that in USA, Japan, Poland, and Ukraine. Secondly, we examine socio-economic hardship and political instability in pre-industrial Mali. Thirdly, we examine patterns of psychological reaction to political and social change during the study period. Our findings have implications for comparisons and generalizations across times and cultures about the contribution of socio-environmental conditions to over-time change in personality.
