Cities in American federalism: evidence on state-local government conflict from a survey of mayors

Previous scholarship on American federalism has largely focused on the national government's increasingly conflictual relationship with the states. While some studies have explored the rise of mandates at the state level, there has been comparatively less attention on state–local relationships. Using a new survey of mayors, we explore variations in local government attitudes towards their state governments. We find some evidence that, regardless of partisanship, mayors in more conservative states are unhappy about state funding and—especially—regulations. More strikingly, we also uncover a partisan mismatch in which Democratic mayors provide especially negative ratings of their state’s funding and—even more strongly—regulations. These findings have important implications for state–local relations as cities continue to become more Democratic and Republicans increasingly dominate state-level contests

Do mayors run for higher office? New evidence on progressive ambition

The mayor’s office potentially offers a launchpad for statewide and national political ambitions. We know relatively little, however, about how frequently mayors actually run for higher office, and which mayors choose to do so. This article combines longitudinal data on the career paths of the mayors of 200 big cities with new survey and interview data to investigate these questions. While we find that individual and city traits—especially gender—have some predictive power, the overwhelming story is that relatively few mayors—just under one-fifth—ever seek higher office. We suggest that ideological, institutional, and electoral factors all help to explain why so few mayors exhibit progressive ambition

Post-Newtonian Approximation in Maxwell-Like Form

The equations of the linearized first post-Newtonian approximation to general relativity are often written in "gravitoelectromagnetic" Maxwell-like form, since that facilitates physical intuition. Damour, Soffel and Xu (DSX) (as a side issue in their complex but elegant papers on relativistic celestial mechanics) have expressed the first post-Newtonian approximation, including all nonlinearities, in Maxwell-like form. This paper summarizes that DSX Maxwell-like formalism (which is not easily extracted from their celestial mechanics papers), and then extends it to include the post-Newtonian (Landau-Lifshitz-based) gravitational momentum density, momentum flux (i.e. gravitational stress tensor) and law of momentum conservation in Maxwell-like form. The authors and their colleagues have found these Maxwell-like momentum tools useful for developing physical intuition into numerical-relativity simulations of compact binaries with spin.Comment: v4: Revised for resubmission to Phys Rev D, 6 pages. v3: Reformulated in terms of DSX papers.

Few big-city mayors see running for higher office as appealing

Former mayors are not unknown in Congress and in governors' mansions - but does running a big city act as a springboard for higher office? To answer this question, Katherine Levine Einstein, David M. Glick, Maxwell Palmer and Robert J. Pressel collected data from nearly 200 large US cities and interviewed 94 mayors. They find that mayors are not likely to seek higher office, and tend to have little interest in doing so – especially if they are women or black

Phenomenology of the Gowdy Universe on T3×RT^3 \times R

Numerical studies of the plane symmetric, vacuum Gowdy universe on $T^3 \times R$ yield strong support for the conjectured asymptotically velocity term dominated (AVTD) behavior of its evolution toward the singularity except, perhaps, at isolated spatial points. A generic solution is characterized by spiky features and apparent ``discontinuities'' in the wave amplitudes. It is shown that the nonlinear terms in the wave equations drive the system generically to the ``small velocity'' AVTD regime and that the spiky features are caused by the absence of these terms at isolated spatial points.Comment: 19 pages, 21 figures, uses Revtex, psfi

Monte Carlo transient phonons transport in silicon and germanium at nanoscales

Heat transport at nanoscales in semiconductors is investigated with a statistical method. The Boltzmann Transport Equation (BTE) which characterize phonons motion and interaction within the crystal lattice has been simulated with a Monte Carlo technique. Our model takes into account media frequency properties through the dispersion curves for longitudinal and transverse acoustic branches. The BTE collisional term involving phonons scattering processes is simulated with the Relaxation Times Approximation theory. A new distribution function accounting for the collisional processes has been developed in order to respect energy conservation during phonons scattering events. This non deterministic approach provides satisfactory results in what concerns phonons transport in both ballistic and diffusion regimes. The simulation code has been tested with silicon and germanium thin films; temperature propagation within samples is presented and compared to analytical solutions (in the diffusion regime). The two materials bulk thermal conductivity is retrieved for temperature ranging between 100 K and 500 K. Heat transfer within a plane wall with a large thermal gradient (250 K-500 K) is proposed in order to expose the model ability to simulate conductivity thermal dependence on heat exchange at nanoscales. Finally, size effects and validity of heat conduction law are investigated for several slab thicknesses

Position-momentum local realism violation of the Hardy type

We show that it is, in principle, possible to perform local realism violating experiments of the Hardy type in which only position and momentum measurements are made on two particles emanating from a common source. In the optical domain, homodyne detection of the in-phase and out-of-phase amplitude components of an electromagnetic field is analogous to position and momentum measurement. Hence, local realism violations of the Hardy type are possible in optical systems employing only homodyne detection.Comment: 10 pages, no figures, to be published in Physical Review

Who participates in local government? Evidence from meeting minutes

Scholars and policymakers have highlighted institutions that enable community participation as a potential buffer against existing political inequalities. Yet these venues may bias policy discussions in favor of an unrepresentative group of individuals. To explore who participates, we compile a novel data set by coding thousands of instances of citizens speaking at planning and zoning board meetings concerning housing development. We match individuals to a voter file to investigate local political participation in housing and development policy. We find that individuals who are older, male, longtime residents, voters in local elections, and homeowners are significantly more likely to participate in these meetings. These individuals overwhelmingly (and to a much greater degree than the general public) oppose new housing construction. These participatory inequalities have important policy implications and may be contributing to rising housing costs.Accepted manuscrip

Quantum codewords contradict local realism

Quantum codewords are highly entangled combinations of two-state systems. The standard assumptions of local realism lead to logical contradictions similar to those found by Bell, Kochen and Specker, Greenberger, Horne and Zeilinger, and Mermin. The new contradictions have some noteworthy features that did not appear in the older ones.Comment: 9 pages LaTeX, 1 figur
