The effects of state EITC expansion on children’s health

This brief examines the impact of state-level adoption of Earned Income Tax Credits (EITCs) on a set of health-related outcomes for children, including: (1) health insurance coverage, (2) use of preventive medical and dental care, and (3) health status measures including maternal reports of child health and body mass index. It also considers the possibility that the effect of the EITC on these outcomes may vary depending on where a child lives; families in urban and rural communities have different access to medical care and other resources that promote good health. Author Reagan Baughman reports that the expansion of state EITCs is associated with lower rates of public health insurance coverage and greater rates of private health insurance coverage among children. In addition, implementation of a state EITC appears to be associated with a significant improvement in a child\u27s health status for children ages 11 to 14 as reported by the child\u27s mother

Using Evaluation to Improve Grantmaking: What's Good for the Goose is Good for the Grantor

Over the past decade, evaluation has become an increasingly prominent (albeit vexing) function within philanthropy. More and more foundations are beginning to devote at least minimal levels of resources to evaluate the programs they fund. The topic of evaluation appears more and more at professional conferences. Membership in Grantmakers Evaluation Network -- an "affinity group" of foundation representatives interested in promoting evaluation -- has mushroomed to over 400. As the "demand" for evaluation has increased among foundations, the market has begun to fill up with a mixed bag of consultants (from both academia and the private sector) willing to supply their services. Particularly this last indicator suggests that evaluation will take root in the philanthropic sector. Yet, although evaluation is becoming a more popular activity among foundations, its potential is far from being realized

Variables in turbine erosion

Study of impact erosion in the operation of turbomachinery is undertaken to predict the results for particular designs. The test program investigates the effects of turbine stator blade shape, rotor blade shape, and variations in test conditions

Low wages prevalent In direct care and child care workforce

The large-scale movement of women into the paid labor market has brought sweeping change into family life and also in who cares for the elderly and children. This brief studies workers in two low wage, predominantly female care-giving occupations plagued with high turnover, direct care workers and child care workers. It provides a better understanding of how they fare when compared with other female workers and discusses factors that contribute to their continued employment

How Do States Formulate Medicaid and SCHIP Policy? Economic and Political Determinants of State Eligibility Levels

We exploit the existence of substantial variation in state policies toward public health insurance for children between 1990 and 2002 to estimate the economic and political determinants of state eligibility levels. Controlling for state and year effects, eligibility levels are not significantly associated with either the percentage of uninsured children in the state or the eligibility policy of neighboring states; further, variation in eligibility levels within state is negatively associated with both the federal matching rate and state fiscal capacity. We also observe that state political preferences, measured by the Democrats share of seats in the lower chamber of the state legislature, are a relatively important a determinant of state eligibility levels. However, other political factors, such as party control of state government, voter turnout, legislative term limits and campaign finance regulations do not influence state eligibility levels.Medicaid, SCHIP, Political Economy, Race-to-the-Bottom

Encapsulated thermoacoustic projector based on freestanding carbon nanotube film

A suspended nanotube film (or films) producing sound by means of the thermoacoustic (TA) effect is encapsulated between two plates, at least one of which vibrates, to enhance sound generation efficiency and protect the film. To avoid the oxidation of carbon nanotubes at elevated temperatures and reduce the thermal inertia of surrounding medium the enclosure is filled with inert gas (preferably with high heat capacity ratio, γ=Cp/Cv, and low heat capacity, Cp). To generate sound directly as the first harmonic of applied audio signal without use of an energy consuming dc biasing, an audio signal modulated carrier frequency at much higher frequency is used to provide power input. Various other inventive means are described to provide enhanced projected sound intensity, increased projector efficiency, and lengthened projector life, like the use of infrared reflecting coatings and particles on the projector plates, non-parallel sheet alignment in sheet stacks, and cooling means on one projector side.Board of Regents, University of Texas Syste

Development of Nickel-Titanium Graded Composition Components

The potential of various manufacturing methods was evaluated for producing nickel-titanium graded composition material. The selected test case examined attachment brackets that join nickel-based metallic thermal protection systems to titanium-based launch vehicle structure. The proposed application would replace nickel-based components with graded composition components in an effort to alleviate service induced thermal stresses. Demonstration samples were produced by laser direct metal deposition, flat wire welding, and ultrasonic consolidation. Microstructure, general bond quality, and chemistry were evaluated for the components.Mechanical Engineerin

Specific impairments in cognitive development: a dynamical systems approach

Neuropsychologists have frequently proposed that domain-specific deficits can be observed in developmental disorders (e.g., phonology in dyslexia, theory of mind in autism, grammar in specific language impairment, face recognition in prosopagnosia, mathematics in dyscalculia). These deficits appeal to a modular cognitive architecture. However, specific developmental deficits are at odds with theories that posit a high degree of interactivity between cognitive abilities across development. If there are early deficits, why do these not spread across the cognitive system during development? Or experience compensatory help from other initially intact components? We address these questions within a dynamical systems framework (van der Maas et al., 2006). We explore the conditions for deficit spread and compensation for a range of possible cognitive architectures, from modular to fully distributed. While preliminary, the results point to the importance of specifying precisely the normal developmental architecture of a system prior to characterizing patterns of impairment that might emerge from it
