Objectives. Although employment among welfare mothers increased substantially following the 1996 welfare reform, some former welfare recipients failed to find stable employment. We review the extent to which low‐income mothers are without work and cash welfare for long periods of time and seek to understand the correlates of becoming chronically disconnected. Methods. We analyze data from a 1997–2003 panel study of single mothers who received cash welfare in an urban county in Michigan in February 1997. We develop a new measure of the extent to which former recipients are “chronically disconnected” from both employment and cash welfare and estimate regression models of the correlates of this economic outcome. Results. About 9 percent of respondents became chronically disconnected, defined as being without employment and cash welfare during at least one‐quarter of the months during the 79‐month study period. Important correlates of becoming chronically disconnected include having a physical limitation, having a learning disability, using illegal drugs or meeting the diagnostic screening criteria for alcohol dependence, and having no car or driver license. The chronically disconnected are more likely to have lost a job than to have lost welfare benefits and are more economically disadvantaged than those with regular sources of economic support. Conclusions. To reduce the number of women who fail to make a successful transition from welfare to work, more attention should be given to programs and policies that attempt to reconnect disconnected women to regular sources of economic support. 相似文献

Past research suggests that problem solving and/or decision behavior can be altered and improved by the changes in the way information is accessed and displayed. Also, researchers have found that the usefulness of different information display formats are contingent on the characteristics of the problem task. This research investigated the impact on problem solving when accessing and using information from linear and nonlinear systems. Also, the research investigated problem-solving performance of linear and nonlinear systems when applied to different combinations of problem tasks. In a laboratory setting, linear and nonlinear systems were developed to conduct this experiment. This experiment used 64 graduate business students in a two-factor repeated-measures design employing a multivariate analysis of variance to analyze the data. Repeated measures were conducted to analyze the experimental group under both linear and nonlinear treatments. The findings from the study support the notion that the nonlinear system resulted in superior problem solving and higher levels of user satisfaction than the linear system. Specifically, the nonlinear system enabled users to make faster and more accurate decisions on perceptual problem tasks than did the linear system. For analytical problem tasks, users performed faster with the nonlinear system; however, there was no significant difference in accuracy. User satisfaction was higher with the nonlinear system under both perceptual and analytical tasks. 相似文献
