Welfare policy: The administrative frontier

The process of national welfare reform has been overtaken by local reform as states implement experimental programs under federal waivers. Most of these initiatives attempt to enforce work or otherwise control the lives of the dependent in return for support. Research, which traditionally stressed the social and economic aspects of welfare or poverty, must be reoriented to address the administrative issues raised by the emerging paternalism. A combination of field interviewing and analyses of reporting data can track implementation and connect program operations to outcomes. Such research assesses program performance less surely than experimental trials do but is more useful to operators and more relevant to current program goals. The frontiers of welfare research, like welfare policy, are institutional.

Are welfare employment programs effective?

Employment programs meant to place welfare adults in work or training became an important part of Aid to Families with Dependent Children starting in the 1980s. These programs are effective if one means that they have positive impacts in evaluations, less so if one expects them to make a large and visible change in the welfare problem. In programs evaluated by the Manpower Demonstration Research Corporation, impacts on employment, earnings, and dependency are small in absolute terms but somewhat larger as a percentage of the control group mean. Impacts are understated in some studies because randomization occurred only after enrollment in the work program or because control group members had access to equivalent services. Results are also depressed by the failure of many experimentals to participate in the tested program. Programs raise the activity of experimentals in work-related activities much more than they raise earnings or employment. Effects on dependency are understated because evaluations do not capture deterrence effects. The sharp decline in AFDC in Wisconsin in recent years suggests the power of work requirements to drive the rolls down.

Utilizing Community Resources to Reduce the Presence of Type 2 Diabetes in Rural Youth

The purpose of this study was to implement a program designed to promote diabetes prevention activities among preadolescents in a rural southern setting using a day camp intervention. Participants in the study were eleven youth from a rural Alabama county who participated in a week-long half-day camp administered by local and community volunteers. Change scores were used to compare pre- to post- to follow-up measures for camp participant responses. Program results consistently demonstrated that the day camp was theoretically sound and that program activities positively impacted behavioral antecedents. This study demonstrated the feasibility of conducting a diabetes prevention day camp in a rural environment. Insights from this intervention can assist planners in rural environments to tailor similar initiatives in rural settings. Given the complicated nature of behavior change, a day camp approach of this length does not modify the behaviors of participants. Behavior changes may take considerably longer to initiate

Far infrared supplement: Catalog of infrared observations

The Far Infrared Supplement: catalog of infrared observations summarizes all infrared astronomical observations at far infrared wavelengths published in the scientific literature between 1965 and 1982. The Supplement list contains 25% of the observations in the full catalog of infrared observations (C10), and essentially eliminates most visible stars from the listings. The Supplement is more compact than the main Catalog (it does not contain the bibliography and position index of the C10), and is intended for easy reference during astronomical observations

Far infrared supplement: Catalog of infrared observations

The development of a new generation of orbital, airborne and ground-based infrared astronomical observatory facilities, including the infrared astronomical satellite (IRAS), the cosmic background explorer (COBE), the NASA Kuiper airborne observatory, and the NASA infrared telescope facility, intensified the need for a comprehensive, machine-readable data base and catalog of current infrared astronomical observations. The Infrared Astronomical Data Base and its principal data product, this catalog, comprise a machine-readable library of infrared (1 micrometer to 1000 micrometers) astronomical observations published in the scientific literature since 1965

Catalog of infrared observations including: Bibliography of infrared astronomy and index of infrared source positions

The Catalog of Infrared Observations and its Far Infrared Supplement summarize all infrared astronomical observations at infrared wavelengths published in the scientific literature between 1965 and 1982. The Catalog includes as appendices the Bibliography of infrared astronomy which keys observations in the Catalog with the original journal references, and the index of infrared source positions which gives source positions for alphabetically listed sources in the Catalog. The Catalog data base contains over 85,000 observations of about 10,000 infrared sources, of which about 2,000 have no known visible counterpart

Cost-effectiveness of physical fitness training for stroke survivors

Background Physical fitness is impaired after stroke, yet fitness training after stroke reduces disability. Several international guidelines recommend that fitness training be incorporated as part of stroke rehabilitation. However, information about cost-effectiveness is limited. Methods A decision tree model was used to estimate the cost-effectiveness of a fitness programme for stroke survivors vs. relaxation (control group). This was based on a published randomised controlled trial, from which evidence about quality of life was used to estimate Quality Adjusted Life Years. Costs were based on the cost of the provision of group fitness classes within local community centres and a cost per Quality Adjusted Life Year was calculated. Results The results of the base case analysis found an incremental cost per Quality Adjusted Life Year of £2,343. Conclusions Physical fitness sessions after stroke are a cost-effective intervention for stroke survivors. This information will help make the case for the development of new services

Improving CMB non-Gaussianity estimators using tracers of local structure

Local non-Gaussianity causes correlations between large scale perturbation modes and the small scale power. The large-scale CMB signal has contributions from the integrated Sachs Wolfe (ISW) effect, which does not correlate with the small scale power. If this ISW contribution can be removed, the sensitivity to local non-Gaussianity is improved. Gravitational lensing and galaxy counts can be used to trace the ISW contribution; in particular we show that the CMB lensing potential is highly correlated with the ISW signal. We construct a nearly-optimal estimator for the local non-Gaussianity parameter \fnl and investigate to what extent we can use this to decrease the variance on {\fnl}. We show that the variance can be decreased by up to $20\%$ at Planck sensitivity using galaxy counts. CMB lensing is a good bias-independent ISW tracer for future more sensitive observations, though the fractional decrease in variance is small if good polarization data is also available.Comment: 8 pages, 3 figures.
