Complex, multihazard risks such as private groundwater contamination necessitate multiannual risk reduction actions including seasonal, weather-based hazard evaluations. In the Republic of Ireland (ROI), high rural reliance on unregulated private wells renders behavior promotion a vital instrument toward safeguarding household health from waterborne infection. However, to date, pathways between behavioral predictors remain unknown while latent constructs such as extreme weather event (EWE) risk perception and self-efficacy (perceived behavioral competency) have yet to be sufficiently explored. Accordingly, a nationwide survey of 560 Irish private well owners was conducted, with structural equation modeling (SEM) employed to identify underlying relationships determining key supply management behaviors. The pathway analysis (SEM) approach was used to model three binary outcomes: information seeking, post-EWE action, and well testing behavior. Upon development of optimal models, perceived self-efficacy emerged as a significant direct and/or indirect driver of all three behavior types—demonstrating the greatest indirect effect (β = −0.057) on adoption of post-EWE actions and greatest direct (β = 0.222) and total effect (β = 0.245) on supply testing. Perceived self-efficacy inversely influenced EWE risk perception in all three models but positively influenced supply awareness (where present). Notably, the presence of a vulnerable (infant and/or elderly) household member negatively influenced adoption of post-EWE actions (β = −0.131, p = 0.016). Results suggest that residential and age-related factors constitute key demographic variables influencing risk mitigation and are strongly mediated by cognitive variables—particularly self-efficacy. Study findings may help contextualize predictors of private water supply management, providing a basis for future risk-based water interventions. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Intersecting discourses on race and sexuality: compounded colonization among LGBTTQ American Indians/Alaska Natives 总被引:1,自引:0,他引:1

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. 相似文献

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 相似文献

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. 相似文献

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. 相似文献
