Regional young child poverty in 2008: rural Midwest sees increased poverty, while urban Northeast rates decrease

In 2008, America\u27s recession affected poverty rates for children under age 6 unevenly, with rates in the rural Midwest rising significantly, while rates in northeastern central cities fell slightly. And in the rural South, where more than 30 percent of young children are poor, poverty rates for young children persisted at a very high rate. This is an analysis of American Community Survey data released by the U.S. Census Bureau

Child tax credit expansion increases number of families eligible for a refund

The analysis shows that more than 500,000 rural families, or almost 9 percent of rural families, will become newly eligible for the Child Tax Credit under the expansion included in the American Recovery and Reinvestment Act. Within these families are an estimated 900,000 rural children. The proportion of urban families benefiting from the expanded Child Tax Credit is slightly lower than in rural areas, but only 5 percent of suburban families are newly eligible for the credit

Low energy bounds on Poincare violation in causal set theory

In the causal set approach to quantum gravity, Poincar\'{e} symmetry is modified by swerving in spacetime, induced by the random lattice discretization of the space-time structure. The broken translational symmetry at short distances is argued to lead to a residual diffusion in momentum space, whereby a particle can acquire energy and momentum by drift along its mass shell and a system in equilibrium can spontaneously heat up. We consider bounds on the rate of momentum space diffusion coming from astrophysical molecular clouds, nuclear stability and cosmological neutrino background. We find that the strongest limits come from relic neutrinos, which we estimate to constrain the momentum space diffusion constant by $k < 10^{-61} {\rm GeV}^3$ for neutrinos with masses $m_\nu > 0.01 {\rm eV}$, improving the previously quoted bounds by roughly 17 orders of magnitude.Comment: Additional discussion about behavior of alpha particles in nuclei added.

Forty-three percent of eligible rural families can claim a larger credit with EITC expansion

This policy brief on the changes to the Earned Income Tax Credit in the ARRA also shows that families with three or more children and married couples will receive an increased refund under these new EITC rules for tax years 2009 and 2010. Many families in urban and suburban communities will also see increased benefits under these new provisions

Seventy-eight percent of working rural families to receive full Making Work Pay tax credit

The Making Work Pay Tax Credit provides eligible U.S. workers with additional money in each paycheck throughout the year. The fact sheet shows that 78 percent of rural working families will receive the full amount of the credit, while an additional 10 percent of families will receive a partial credit due to low earnings or high earnings. These tax credits, along with the expansion to the Child Tax Credit, are an important financial boost to families in rural America, particularly low-income working families

Causal sets and conservation laws in tests of Lorentz symmetry

Many of the most important astrophysical tests of Lorentz symmetry also assume that energy-momentum of the observed particles is exactly conserved. In the causal set approach to quantum gravity a particular kind of Lorentz symmetry holds but energy-momentum conservation may be violated. We show that incorrectly assuming exact conservation can give rise to a spurious signal of Lorentz symmetry violation for a causal set. However, the size of this spurious signal is much smaller than can be currently detected and hence astrophysical Lorentz symmetry tests as currently performed are safe from causal set induced violations of energy-momentum conservation.Comment: 8 pages, matches version published in PR

The strong Feller property for singular stochastic PDEs

We show that the Markov semigroups generated by a large class of singular stochastic PDEs satisfy the strong Feller property. These include for example the KPZ equation and the dynamical $\Phi^4_3$ model. As a corollary, we prove that the Brownian bridge measure is the unique invariant measure for the KPZ equation with periodic boundary conditions

Over 3 million low-income children in rural areas face cut in child tax credit if recovery act improvement expires

According to this new research, at the end of 2010, the Child Tax Credit improvements that were included in the 2009 American Recovery and Reinvestment Act will expire if Congress does not extend them. If this happens, low-income working families across America will be affected

Child Care Expenses Push Many Families Into Poverty

In this fact sheet, authors Marybeth Mattingly and Christopher Wimer use the Supplemental Poverty Measure to assess the extent to which child care costs are pushing families with young children into poverty or preventing them from escaping it. They focus on families with at least one child under age 6 who report any child care expenditures. They report that one third of poor families who pay for child care for their young children are pushed into poverty by their child care expenses. Families most often pushed into poverty by child care expenses include households with three or more children, those headed by a single parent, those with a black or Hispanic head of household, and those headed by someone with less than a high school degree or by someone who does not work full time. Their findings suggest that lowering out-of-pocket child care expenses for families with young children would serve to reduce poverty. Additionally, things like increased subsidies may expand access to higher quality child care or open the door to increased labor force participation

Limited Access to AP Courses for Students in Smaller and More Isolated Rural School Districts

This brief assesses trends in access to, enrollment in, and success in Advanced Placement (AP) coursework in relation to school district poverty, racial composition, and urbanicity. It uses data merged from the 2011–2012 Civil Rights Data Collection (CRDC), the 2012 Small Area Income and Poverty Estimates (SAIPE), and the 2010 Decennial U.S. Census. Authors Douglas Gagnon and Marybeth Mattingly report that nearly one-half (47.2 percent) of rural districts have no secondary students enrolled in AP courses, compared with only 20.1 percent of town, 5.4 percent of suburban, and 2.6 percent of urban districts. Remote rural districts with small populations are nearly ten times less likely to offer access to AP courses than are larger rural districts on the fringe of urbanized areas. Even in districts that have some access to AP coursework, the proportion of students enrolled in an AP course in urban and suburban districts is roughly double that in town and rural districts. Students in more affluent districts have higher success rates than those in less affluent districts, regardless of place type
