Critical sets in the elementary abelian 2- and 3- groups
In 1998, Khodkar showed that the minimal critical set in the Latin square
corresponding to the elementary abelian 2-group of order 16 is of size at most
124. Since the paper was published, improved methods for solving integer
programming problems have been developed. Here we give an example of a critical
set of size 121 in this Latin square, found through such methods. We also give
a new upper bound on the size of critical sets of minimal size for the
elementary abelian 2-group of order : . We
speculate about possible lower bounds for this value, given some other results
for the elementary abelian 2-groups of orders 32 and 64. An example of a
critical set of size 29 in the Latin square corresponding to the elementary
abelian 3-group of order 9 is given, and it is shown that any such critical set
must be of size at least 24, improving the bound of 21 given by Donovan,
Cooper, Nott and Seberry.Comment: 9 page
Household reports of energy assistance receipt increased 48 percent during recession: Proposed cuts threaten vulnerable families
This brief examines heating assistance usage and the implications of President Obama\u27s 2012 budget proposal to cut 5.1 billion energy assistance fund for low-income families at a time when families are struggling with higher energy costs amid a difficult economy. The federal Low-Income Home Energy Assistance Program (LIHEAP) assists vulnerable families in paying their home heating and cooling bills. Nationwide, from the winter of 2006/2007 to the winter of 2009/2010, there was a 48 percent increase in households receiving energy assistance. This growth appears to have accelerated with the recession, particularly in the rural Northeast and Midwest. Many more families are eligible than receive assistance. Brief author Jessica Bean discusses how proposed cuts would have a concrete and immediate impact on families, particularly those in rural areas and in harsh winter climates
Reliance on supplemental nutrition assistance program continued to rise post-recession
This brief uses data from the 2007, 2009, and 2010 American Community Survey to provide an up-to-date look at changes in SNAP receipt over the course of the recession

Renters more often burdened by housing costs after recession: Nearly half of all renters spent over 30 percent of income on housing by 2010
This brief uses data from the 2007 and 2010 American Community Survey to document changes in the proportion of household income spent on rental costs (rent plus utilities) during the Great Recession, by region (Northeast, Midwest, South, and West) and place type (rural, suburban, or central city location). Particular attention is paid to how patterns of cost burden vary among renters of different ages and income levels and to the policy implications of these findings. Author Jessica Bean reports that nationwide, nearly half (49 percent) of all renters were “cost burdened” in 2010, spending more than 30 percent of their income on housing costs, with the highest rates occurring in the West and in central cities. Renters under the age of 25 were most often cost burdened both pre- and post-recession, with nearly 60 percent of young renters spending more than 30 percent of their income on rent in 2010
