Resource use of rural low-income families caring for children with disabilities

The Personal Responsibility Work Opportunity Reconciliation Act, Pub.L. 104-193 (PRWORA) was passed creating the Temporary Assistance to Needy Families (TANF) program. Since the passage of PRWORA, many families were able to leave the welfare rolls while those remaining on welfare were likely composed of families facing barriers to leaving, such as caring for children with disabilities. This project addresses the gaps in knowledge regarding low-income families caring for children with disabilities by conducting qualitative research investigating the resources used by these families to find and keep employment and child care. The study used a sample from a research project entitled ‘Rural Families Speak’ and examined the data of 26 families caring for children with disabilities. Analysis resulted in policy recommendations for increasing the efficacy of the programs designed to help these families.     

Employed Rural,Low-Income,Single Mothers’ Family and Work Over Time

The purpose of this qualitative research study was to examine how low-income, single mothers manage their family and work lives. Analysis was based on longitudinal data collected from 28 rural, low-income, single mothers across 11 states who were continuously employed over three waves. Four main themes were identified: demands from family and work, resources the mothers used to maintain employment, work-family conflict, and strategies to retain employment. This study concludes that despite all the difficulties, mothers try to utilize their limited resources and adopt strategies for combining family and work life even though their demands and resources vary over time. Mothers employed in the same jobs receive consistent support from families. Implications for child care and leave policies are discussed.     

Statistical Inference for Stochastic Dominance and for the Measurement of Poverty and Inequality

We derive the asymptotic sampling distribution of various estimators frequently used to order distributions in terms of poverty, welfare, and inequality. This includes estimators of most of the poverty indices currently in use, as well as estimators of the curves used to infer stochastic dominance of any order. These curves can be used to determine whether poverty, inequality, or social welfare is greater in one distribution than in another for general classes of indices and for ranges of possible poverty lines. We also derive the sampling distribution of the maximal poverty lines up to which we may confidently assert that poverty is greater in one distribution than in another. The sampling distribution of convenient dual estimators for the measurement of poverty is also established. The statistical results are established for deterministic or stochastic poverty lines as well as for paired or independent samples of incomes. Our results are briefly illustrated using data for four countries drawn from the Luxembourg Income Study data bases.     

Intersecting discourses on race and sexuality: compounded colonization among LGBTTQ American Indians/Alaska Natives

This article examines discourses on race and sexuality in scientific literature during the late-nineteenth and early-twentieth centuries in context of U.S. settler colonialism. It uses a theoretical and methodological intersectional perspective to identify rhetorical strategies deployed in discursive representations salient to lesbian, gay, bisexual, transgender, Two-Spirit, and queer American Indians and Alaska Natives. These representations reflect a context of compounded colonization, a historical configuration of co-constituting discourses based on cultural and ideological assumptions that invidiously marked a social group with consequential, continued effects. Hence, language is a vector of power and a critical vehicle in the project of decolonization.     

Some tests for uniformity of circular distributions powerful against multimodal alternatives

The author introduces new statistics suited for testing uniformity of circular distributions and powerful against multimodal alternatives. One of them has a simple expression in terms of the geometric mean of the sample of chord lengths. The others belong to a family indexed by a continuous parameter. The asymptotic distributions under the null hypothesis are derived. We compare the power of the new tests against Stephens's alternatives with those of Ajne, Watson, and Hermans‐Rasson's tests. Some of the new tests are the most powerful when the alternative has three or four modes. A heuristic justification of this feature is given. An application to the analysis of archaeological data is provided. The Canadian Journal of Statistics 38:80–96; 2010 © 2010 Statistical Society of Canada     

THE JOINT DESIGN OF UNEMPLOYMENT INSURANCE AND EMPLOYMENT PROTECTION: A FIRST PASS

Unemployment insurance and employment protection are typically discussed and studied in isolation. In this paper, we argue that they are tightly linked, and we focus on their joint optimal design in a simple model, with risk‐averse workers, risk‐neutral firms, and random shocks to productivity. We show that, in the “first best,”unemployment insurance comes with employment protection—in the form of layoff taxes; indeed, optimality requires that layoff taxes be equal to unemployment benefits. We then explore the implications of four broad categories of deviations from first best: limits on insurance, limits on layoff taxes, ex post wage bargaining, and ex ante heterogeneity of firms or workers. We show how the design must be modified in each case. Finally, we draw out the implications of our analysis for current policy debates and reform proposals, from the financing of unemployment insurance, to the respective roles of severance payments and unemployment benefits.     

Fisher's Information for Discretely Sampled Lévy Processes

This paper studies the asymptotic behavior of Fisher's information for a Lévy process discretely sampled at an increasing frequency. As a result, we derive the optimal rates of convergence of efficient estimators of the different parameters of the process and show that the rates are often nonstandard and differ across parameters. We also show that it is possible to distinguish the continuous part of the process from its jumps part, and even different types of jumps from one another.     

A Risk-Benefit Analysis of French High Fish Consumption: A QALY Approach

The health risk and the nutritional benefit of a food are usually assessed separately. Toxicologists recommend limiting the consumption of certain fish because of methylmercury; while nutritionists recommend eating more oily fish because of omega 3. A common evaluation is imperative to provide coherent recommendations. In order to evaluate the risks along with the benefits related to fish consumption, a common metric based on the quality-adjusted life year (QALY) method has been used. The impact of a theoretical change from a medium n-3 PUFAs intake to a high intake is studied, in terms of the cardiovascular system (CHD mortality, stroke mortality and morbidity) and on fetal neuronal development (IQ loss or gain). This application can be considered as a sensitive analysis of the model used and looks at the impact of changing the dose-response relationships between cardiovascular diseases and n-3 PUFAs intakes. Results show that increasing fish consumption may have a beneficial impact on health. However, the confidence interval of the overall estimation has a negative lower bound, which means that this increase in fish consumption may have a negative impact due to MeHg contamination. Some limits of the QALY approach are identified. The first concerns determination of the dose-response relationships. The second concerns the economic origins of the approach and of individual preferences. Finally, since only one beneficial aspect and one risk element were studied, consideration should be given to how other beneficial and risk components may be integrated in the model.
