Unemployment Insurance and Low-Educated Single Working Mothers Before and After Welfare Reform

Using the Survey of Income and Program Participation (SIPP), a nationally representative, longitudinal survey, this study examines changing levels of Unemployment Insurance (UI) eligibility and benefit receipt among working low-educated single mothers, 1990–2005. It also examines changing participation in cash welfare and the Food Stamp Program (FSP). Relative to single childless women, there has been no increase in UI benefit receipt among single mothers entering a spell of unemployment in the postreform period, even though single mothers have increased their relative rates of UI eligibility. Because of declining cash assistance receipt, UI became a more common income support than cash assistance for this population during the period 2001–2005. Furthermore, the probability of accessing FSP for low-educated single mothers entering a spell of unemployment increased in the years 2001–2005. As a result, the proportion of this population accessing benefits from one or more of these programs remained virtually unchanged across the study period.Welfare Reform, Unemployment Insurance, Low-educated Single Mothers

A Single Scale Theory for Cold and Hot Dark Matter

We show that a recently proposed extension of the MSSM can provide a scenario where both the cold and hot dark matter of the universe owe their origin to a single scale connected with the breakdown of the global B-L symmetry. The susy partner of the majoron and the light Majorana neutrinos are the cold and hot dark matter candidates respectively in this model and their desired relative abundances emerge when the scale of B-L symmetry breaking is in the TeV range.Comment: UMD-PP-94-102 (latex file; 15 pages

The Development of an Unequal Social Safety Net: A Case Study of the Employer-based Health Insurance (Non) System

The U.S. social safety net exacerbates labor market inequalities rather than ameliorating them. This paper traces this theme within an important historical case study: the emergence of the employer-based health insurance system. Employers became the dominant and tax-preferred provider of health insurance in the United States without any federal legislative action. Understanding how this happened may inform current reform efforts. This case study highlights two important factors. The first is path dependency, discussed by Skocpol (1992) and Pierson (2000). They argue that the ambiguous divisions of power and a pluralistic governance framework favor incremental processes of social policy formation in the United States. The second factor is the divisions within the American workforce (Esping-Andersen, 1990). Divisions by race and sex have often led to disadvantaged workers being left out or underserved by U.S. social welfare policy

Inflammatory biomarker changes and their correlation with Framingham cardiovascular risk and lipid changes in antiretroviral-naive HIV-infected patients treated for 144 weeks with abacavir/lamivudine/atazanavir with or without ritonavir in ARIES.

Propensity for developing coronary heart disease (CHD) is linked with Framingham-defined cardiovascular risk factors and elevated inflammatory biomarkers. Cardiovascular risk and inflammatory biomarkers were evaluated in ARIES, a Phase IIIb/IV clinical trial in which 515 antiretroviral-naive HIV-infected subjects initially received abacavir/lamivudine + atazanavir/ritonavir for 36 weeks. Subjects who were virologically suppressed by week 30 were randomized 1:1 at week 36 to either maintain or discontinue ritonavir for an additional 108 weeks.

The absolute infrared magnitudes of type Ia supernovae

The absolute luminosities and homogeneity of early-time infrared (IR) light curves of type Ia supernovae are examined. Eight supernovae are considered. These are selected to have accurately known epochs of maximum blue light as well as having reliable distance estimates and/or good light curve coverage. Two approaches to extinction correction are considered. Owing to the low extinction in the IR, the differences in the corrections via the two methods are small. Absolute magnitude light curves in the J, H and K-bands are derived. Six of the events, including five established ``Branch-normal'' supernovae show similar coeval magnitudes. Two of these, SNe 1989B and 1998bu, were observed near maximum infrared light. This occurs about 5 days {\it before} maximum blue light. Absolute peak magnitudes of about -19.0, -18.7 and -18.8 in J, H & K respectively were obtained. The two spectroscopically peculiar supernovae in the sample, SNe 1986G and 1991T, also show atypical IR behaviour. The light curves of the six similar supernovae can be represented fairly consistently with a single light curve in each of the three bands. In all three IR bands the dispersion in absolute magnitude is about 0.15 mag, and this can be accounted for within the uncertainties of the individual light curves. No significant variation of absolute IR magnitude with B-band light curve decline rate, Delta m_{15}(B), is seen over the range 0.87<Delta m_{15}(B)<1.31. However, the data are insufficient to allow us to decide whether or not the decline rate relation is weaker in the IR than in the optical region. IR light curves of type Ia supernovae should eventually provide cosmological distance estimates which are of equal or even superior quality to those obtained in optical studies.Comment: 19 pages, 9 figures, MNRAS in press (includes Referee's changes

Could a Mid-Level Dental Provider Increase Access to Oral Health Care in Michigan?

According to a 2000 Surgeon General’s report, the United States faces an epidemic of unmet oral health needs, the result of both the high cost of care and geographic maldistribution of providers. This article assesses the extent of this unmet health care needs in Michigan, and examines one possible solution: the introduction of a mid-level dental provider (MDP) who could provide preventive and basic restorative care, under the supervision of a Michigan dentist. MDPs in various forms currently practice in over 50 countries including Canada and the U.K. The evidence suggests that a large and rigorous pilot of mid-level dental providers should be undertaken in Michigan, to inform policymakers about the structure’s potential for improving access to oral health care for vulnerable populations in the state
