Overall we find that the analytic models provide good descriptions, generally modeling the various distributions as well as empirical

Our methodology also allows us to determine which random variables show significant variation from site to site, over time

This paper explores the validity of these criticisms using the available empirical evidence and, in turn, evaluates the impact of various reforms to the system. "Welfare" most commonly refers to the Aid to Families with Dependent Children (AFDC) program, which provides cash assistance

Abstract. Estimates of the gas temperature in planetary nebulae obtained from the [O III] emission line ratio and from the Balmer discontinuity indicate differences reaching up to 6000 K (Liu & Danziger 1993). The [O III] temperature is commonly used to obtain the ionic fractions of highly
