The scattering of ff- and pp-modes from ensembles of thin magnetic flux tubes - An analytical approach

Motivated by the observational results of Braun (1995), we extend the model of Hanson & Cally (2014) to address the effect of multiple scattering of f and p-modes by an ensemble of thin vertical magnetic flux tubes in the surface layers of the Sun. As in observational Hankel analysis we measure the scatter and phase shift from an incident cylindrical wave in a coordinate system roughly centred in the core of the ensemble. It is demonstrated that, although thin flux tubes are unable to interact with high order fluting modes individually, they can indirectly absorb energy from these waves through the scatters of kink and sausage components. It is also shown how the distribution of absorption and phase shift across the azimuthal order m depends strongly on the tube position, as well as on the individual tube characteristics. This is the first analytical study into an ensembles multiple scattering regime, that is embedded within a stratified atmosphere.Comment: 20 pages, 8 Figure

Multiple Scattering of Seismic Waves from Ensembles of Upwardly Lossy Thin Flux Tubes

Our previous semi-analytic treatment of f- and p-mode multiple scattering from ensembles of thin flux tubes (Hanson and Cally, Astrophys. J. 781, 125; 791, 129, 2014) is extended by allowing both sausage and kink waves to freely escape at the top of the model using a radiative boundary condition there. As expected, this additional avenue of escape, supplementing downward loss into the deep solar interior, results in substantially greater absorption of incident f- and p-modes. However, less intuitively, it also yields mildly to substantially smaller phase shifts in waves emerging from the ensemble. This may have implications for the interpretation of seismic data for solar plage regions, and in particular their small measured phase shifts.Comment: 9 Pages, 5 Figures. Accepted by Solar Physic

Do Borrower Rights Improve Borrower Outcomes? Evidence from the Foreclosure Process

We evaluate laws designed to protect borrowers from foreclosure. We find that these laws delay but do not prevent foreclosures. We first compare states that require lenders to seek judicial permission to foreclose with states that do not. Borrowers in judicial states are no more likely to cure and no more likely to renegotiate their loans, but the delays lead to a build-up in these states of persistently delinquent borrowers, the vast majority of whom eventually lose their homes. We next analyze a “right-to-cure” law instituted in Massachusetts on May 1, 2008. Using a difference-in-differences approach to evaluate the effect of the policy, we compare Massachusetts with neighboring states that did not adopt similar laws. We find that the right-to-cure law lengthens the foreclosure timeline but does not lead to better outcomes for borrowers.

The Federalist Revolt: An Affirmation or Denial of Popular Sovereignty?

After nearly two centuries of relative neglect by historians, the Federalist revolt of 1793 finally is receiving the attention it deserves. Book-length studies now exist for each of the main Federalist cities, and several articles have considered various aspects of either Federalism or the Federalist revolt.1 We are thus in a position to begin a fuller and more informed evaluation of the character and significance of the Federalist revolt..

Effects of Disability Status of Test Administrator on Attitudes Towards Disabled Person Scores

The effect of test administrator disability status was examined in relation to a standardized scale which measures attitudes towards disabled persons. Conducting the study on two different dates with a total of 88 subjects it was found that filling out the attitude scale in a group with either: a visually impaired; Quadriplegic using a wheelchair; or able-bodied administrator did not result in a significant difference in recorded attitudes. There was, however, an interesting finding in that there was a wide variance of scores within each group. This encourages further data analysis
