This study summarizes the State policy with respect to the determination of need in the Federal-State program of AFDC. The areas discussed are the individual State definitions of need, the content of need standard, the types of persons included in the payment, the amount of income and resources allowed recipient families, the method of determining need, and a comparison of State food allowances...

In the field of occupational hygiene, researchers have been working on developing appropriate methods to estimate human exposure to pesticides in order to assess the risk and therefore to take the due decisions to improve the pesticide management process and reduce the health risks. This paper evaluates dermal exposure models to find the most appropriate. Eight models (i.e., COSHH, DERM, DREAM, ...

I test for welfare-induced migration by comparing AFDC participation in border counties to interior counties in the same state. If migration costs are lower for border county residents, border counties on the high-benefit side of a state border should have higher welfare participation relative to the state's interior counties. Border counties on the low-benefit side should have lower welfare pa...

The genome projects have unearthed an enormous diversity of genes of unknown function that are still awaiting biological and biochemical characterization. These genes, as most others, can be grouped into families based on sequence similarity. The PFAM database currently contains over 2,200 such families, referred to as domains of unknown function (DUF). In a coordinated effort, the four large-s...

The authors explore how to define a welfare spell and how well surveys measure welfare spells. By comparing survey and administrative data from the Work Pays Demonstration Project in California on the receipt of Aid to Families with Dependent Children (AFDC), they find that a substantial amount of administrative churning occurs in administrative data. Through a mixing model of several break len...

UNLABELLED We present TreeDom, a web tool for graphically analysing the evolutionary history of domains in multi-domain proteins. Individual domains on the same protein chain may have distinct evolutionary histories, which is important to grasp in order to understand protein function. For instance, it may be important to know whether a domain was duplicated recently or long ago, to know the ori...

Building on recent work by Rosenzweig (1999), this paper re-examines the effect of AFDC benefits on early non-marital childbearing. Unlike most previous work in this area, Rosenzweig finds a statistically significant and quantitatively large positive effect of AFDC benefits. Using data from the Panel Study of Income Dynamics, we replicate Rosenzweig’s analysis and explore the reasons his findin...

BACKGROUND Explicit comparisons based on the semantic similarity of Gene Ontology terms provide a quantitative way to measure the functional similarity between gene products and are widely applied in large-scale genomic research via integration with other models. Previously, we presented an edge-based method, Relative Specificity Similarity (RSS), which takes the global position of relevant ter...

is not found and the caretaker relative still refuses to cooperate, the caretaker becomes ineligible for benefits, and assistance is provided to the eligible child in tte form of protective payments, without regard to the needs of the caretaker relative. Therefore, if eligibility is determined and/or payments are made prior to the rejection of a good cause claim, it may become necessary . to re...
