Undocumented Immigrants: Myths and Reality

In this article, six common myths about immigrants are debunked

Civic Contributions: Taxes Paid by Immigrants in the Washington, DC, Metropolitan Area

This report estimates the taxes paid by immigrants in the Washington, D.C., area in 1999-2000 and documents their demographics, household composition, income, and dispersal across jurisdictions in the region. The findings in this report are based mostly on analysis of 2000 U.S. Census data, because the census provides the most recent comprehensive data that allow disaggregation by country of origin groups and by many of the region's local jurisdictions. The demographic data in the report are updated through 2004 using the U.S. Current Population Survey. We calculate taxes at both the individual level (e.g., income and payroll taxes) and the household level (e.g., property taxes), but aggregate them up to the household level. Throughout the report we refer to households headed by immigrants (whether citizens, legal immigrants, or unauthorized migrants) as "immigrant households" and compare their incomes and tax payments to households headed by native-born U.S. citizens

Incoherent pion photoproduction on the deuteron with polarization observables I: Formal expressions

Formal expressions are developed for the general five-fold differential cross section of incoherent $\pi$-photoproduction on the deuteron including beam and target polarization. The polarization observables of the cross section are described by various beam, target and beam-target asymmetries for polarized photons and/or polarized deuterons. They are given as bilinear hermitean forms in the reaction matrix elements divided by the unpolarized cross section. In addition, the corresponding observables for the semi-exclusive reaction $\vec d(\vec \gamma,\pi)NN$ are also given.Comment: 11 pages, 1 figur

Public Perceptions of Gender Bias in the Decisions of Female State Court Judges

How are women on the bench, and their decisions, perceived by the public? Many scholars find that gender influences the voting behavior of judges and the assessment of judges by state judicial systems and the American Bar Association. However, few scholars have examined how judge gender affects the way in which the public responds to judicial outcomes. Does the public perceive the decisions of female state court judges as being biased by their gender identity, particularly in cases involving reproductive rights/family law? Also, does the public view female judges on state courts as more likely to rely on ideology when ruling in cases? Using a survey experiment that varies judge gender in a state child custody case, we examine whether respondents exhibit less support for judicial decisions authored by female state court judges. Additionally, we test whether respondents are more likely to perceive the decisions of female state court judges as ideologically biased or as a product of gender influences (as compared to male judges). Finally, we assess whether these effects are conditional on or exacerbated by respondent characteristics such as gender, race, and religiosity. The influence of gender on public response to state court decisions has important implications for our understanding of why certain court decisions find public support and acceptance

Seen and unseen tidal caustics in the Andromeda galaxy

Indirect detection of high-energy particles from dark matter interactions is a promising avenue for learning more about dark matter, but is hampered by the frequent coincidence of high-energy astrophysical sources of such particles with putative high-density regions of dark matter. We calculate the boost factor and gamma-ray flux from dark matter associated with two shell-like caustics of luminous tidal debris recently discovered around the Andromeda galaxy, under the assumption that dark matter is its own supersymmetric antiparticle. These shell features could be a good candidate for indirect detection of dark matter via gamma rays because they are located far from the primary confusion sources at the galaxy's center, and because the shapes of the shells indicate that most of the mass has piled up near apocenter. Using a numerical estimator specifically calibrated to estimate densities in N-body representations with sharp features and a previously determined N-body model of the shells, we find that the largest boost factors do occur in the shells but are only a few percent. We also find that the gamma-ray flux is an order of magnitude too low to be detected with Fermi for likely dark matter parameters, and about 2 orders of magnitude less than the signal that would have come from the dwarf galaxy that produces the shells in the N-body model. We further show that the radial density profiles and relative radial spacing of the shells, in either dark or luminous matter, is relatively insensitive to the details of the potential of the host galaxy but depends in a predictable way on the velocity dispersion of the progenitor galaxy.Comment: ApJ accepte
