Private Child Support: Current and Potential Impacts

This paper examines the effects of a number of methods for enhancing private child support collections: increasing the proportion of those children potentially eligible for child support who get child support awards; using a uniform standard for determining child support obligations; and collecting a greater percentage of current obligations. The paper also estimates the potential of all three methods used in combination to provide income to needy custodial families. The research demonstrates that the current private child support system falls far short of its potential to transfer income from noncustodial to custodial families. Although the use of a normative standard, improved collections, and extending child support to all those potentially eligible will greatly improve the economic circumstances of impoverished custodial families, private child support cannot be viewed as the sole answer for the economic plight of these families. Increased work opportunities and increased public support are also needed

Size-Dependent Transition to High-Dimensional Chaotic Dynamics in a Two-Dimensional Excitable Medium

The spatiotemporal dynamics of an excitable medium with multiple spiral defects is shown to vary smoothly with system size from short-lived transients for small systems to extensive chaos for large systems. A comparison of the Lyapunov dimension density with the average spiral defect density suggests an average dimension per spiral defect varying between three and seven. We discuss some implications of these results for experimental studies of excitable media.Comment: 5 pages, Latex, 4 figure

Trends in Poverty with an Anchored Supplemental Poverty Measure

Poverty measures set a poverty line or threshold and then evaluate resources against that threshold. The official poverty measure is flawed on both counts: it uses thresholds that are outdated and are not adjusted appropriately for the needs of different types of individuals and households; and it uses an incomplete measure of resources which fails to take into account the full range of income and expenses that individuals and households have. Because of these (and other) failings, statistics using the official poverty measure do not provide an accurate picture of poverty or the role of government policies in combating poverty. To address these well-known limitations, the Census Bureau recently implemented a supplemental poverty measure (SPM) which applies an improved set of thresholds and a more comprehensive measure of resources. In this report we apply an alternative poverty measure which differs from the SPM in only one respect. Instead of having a threshold that is re-calculated over time, we use today’s threshold and carry it back historically by adjusting it for inflation using the CPI-U-RS. Because this alternative measure is anchored with today’s SPM threshold, we refer to as an anchored supplemental poverty measure or anchored SPM for short. In addition to the reasons discussed above, another advantage of an anchored SPM (or any absolute poverty measure, for that matter) is that poverty trends resulting from such a measure can be explained by changes in income and net transfer payments (cash or in kind). Trends in poverty based on a relative measure (e.g. SPM poverty), on the other hand, could be due to over time changes in thresholds. Thus, an anchored SPM arguably provides a cleaner measure of how changes in income and net transfer payments have affected poverty historicall

Isomorphism between Non-Riemannian gravity and Einstein-Proca-Weyl theories extended to a class of Scalar gravity theories

We extend the recently proved relation between certain models of Non-Riemannian gravitation and Einstein- Proca-Weyl theories to a class of Scalar gravity theories. This is used to present a Black-Hole Dilaton solution with non-Riemannian connection.Comment: 13 pages, tex file, accepted in Class. Quant. Gra

Waging War on Poverty: Historical Trends in Poverty Using the Supplemental Poverty Measure

Using data from the Consumer Expenditure Survey and the March Current Population Survey, we calculate historical poverty estimates based on the new Supplemental Poverty Measure (SPM) from 1967 to 2012. During this period, poverty as officially measured has stagnated. However, the official poverty measure (OPM) does not account for the effect of near-cash transfers on the financial resources available to families, an important omission since such transfers have become an increasingly important part of government anti-poverty policy. Applying the SPM, which does count such transfers, we find that historical trends in poverty have been more favorable than the OPM suggests and that government policies have played an important and growing role in reducing poverty --- a role that is not evident when the OPM is used to assess poverty. We also find that government programs have played a particularly important role in alleviating child poverty and deep poverty, especially during economic downturns
