As neoliberal ideology and policies gained a foothold in the early 1980s, the social safety net for older Americans contracted. Responsibility for the risks associated with aging, namely retirement income and healthcare costs, was increasingly transferred from the state to the individual. Using data from the Consumer Bankruptcy Project, we report that since 1991, there has been more than a twofold increase in the rate at which older Americans (age 65 and over) file for consumer bankruptcy and an almost fivefold increase in the percentage of older persons in the U.S. bankruptcy system. This magnitude of growth is so large that the broader trend of an aging U.S. population can explain only a small portion of the effect. Respondents report that inadequate income and unmanageable healthcare costs are the chief reasons for their bankruptcies. Our findings suggest that neoliberal policies that offload healthcare costs and retirement savings onto older Americans may facilitate their bankruptcy filings.  相似文献

This article reports on an assessment of contemporary popular knowledge and perceptions of the American Dust Bowl of the 1930s. In a region prone to recurrent drought and evolving resource issues such as the depletion of the Ogallala Aquifer, it follows that knowledge of the Dust Bowl can contribute to understanding and dealing with contemporary and future challenges to the human–environment dynamic of the region. An age-stratified sample of residents from 93 Great Plains counties provided their understandings of the three Dust Bowl concepts (era, event, and region) via questionnaire. When compared with the academic record on the subject, significant variation between respondent age groups was identified. Successively, older generations of the historic Dust Bowl region maintain higher degrees of knowledge than their younger counterparts, regarding this exceptional chapter of American environmental history. This record of knowledge erosion not only speaks to the necessity of enhancing Dust Bowl educational resources, but can be utilized to underscore the salience of studying and documenting adaptive strategies to drought on the American Great Plains.  相似文献

Available research indicates a link between marital conflict and youth outcomes; however, relatively few studies examine these relationships in Latinos, the largest U.S. ethnic group. The present study examines this relationship in both Latino and European American families. Self-report data measuring externalizing and internalizing youth behaviors, along with overt and covert marital conflict, were used in analyses of 788 Latino and 751 European American adolescents. Results support current literature indicating a strong link between marital conflict and youth outcomes, regardless of ethnic group. These associations are similarly related for the differential effects of overt and covert marital conflict on externalizing and internalizing behaviors. However, overt conflict was significantly more predictive of internalizing behaviors than covert conflict. These results yield valuable information for clinical intervention and further research.  相似文献

This study investigated the developmental continuity, stability, and organization of infants' behavioral response to mild stress from 1 to 3 months of age. Changes in infant stress reactivity were expected to coincide with a suspected neurobiological shift around the 2nd month. A total of 53 infants and their mothers participated in this study. At 1 and 3 months, infants' stress reactivity to mild perturbation was assessed by withdrawing a pacifier during nonnutritive sucking. Infant baseline heart rate activity and maternal reports of infant temperament were also obtained. Focusing on facial and vocal negativity, behavioral measures of infant reactivity to pacifier withdrawal were coded from videos. Results showed that developmental continuity and individual instability characterized changes in infant stress reactivity over the 2nd‐month transition. Developmental reorganization was also evidenced by changes in the direction and magnitude of infant stress reactivity in relation to baseline heart period and maternal temperament ratings, respectively. These findings provide direct supporting evidence for the contention that changes in infant stress reactivity to mild perturbation may be a function of developmental shifts in underlying neurobiological mechanisms in early infancy.  相似文献

This paper provides a starting point for preservice and inservice multicultural education teachers to consider five concepts and assumptions from what is generally known as sociocultural theory, derived from the work of Vygotsky, Luria, and Leont'ev (John-Steiner & Mahn, 1996; Luria, 1979). These concepts and assumptions about learning and development, and the links to multicultural education, are expressed by a focus on concrete and abstract artifacts and how these mediate activities. We believe this focus can inform inservice and preservice teachers' present and future practice in diverse settings by providing them with a framework for understanding the psychological tools associated with cultural artifacts embedded in learning and development. Vygotskian perspectives on mediated activity (Wertsch et al., 1993) and the links to other sociocultural concepts and assumptions are followed by a review of three studies (Duke, 2000; Kamberelis & Bovino, 1999; Neuman & Celano, 2001) that are related to Vygotskian perspectives and have implications for multicultural issues and literacy. The implications for multicultural issues and literacy revolve around access and engagement with various types of text (e.g. informational text) and how this in turn affects equity. Finally, a classroom activity to make these Vygotskian concepts and assumptions more accessible and applicable to instruction is presented.  相似文献

Questionnaire items tapping feelings about pregnancy were administered to 173 young, low‐income primiparous Black mothers who either were pregnant or had delivered within the past year. A factor analysis indicated that 11 items together measured mothers’ acceptance of the pregnancies that resulted in the births of their first children. Links to mothers’ later parenting stress, warmth, and their toddlers’ attachment security were explored. Pregnancy acceptance was a negative predictor of one aspect of maternal parenting stress (distress resulting from feelings that parenting is burdensome) and a positive predictor of toddler attachment security. It did not, however, predict another aspect of parenting stress (feelings that interactions with children are not enjoyable) or maternal warmth.  相似文献

Cumulative sum (cusum) methods can be used for monitoring processes and for retrospective (historical) data analysis. Most software only provides the former. The comment by Williamson that retrospective cusum analysis is a neglected area is still true. Though not in vogue, retrospective cusum analysis is useful for investigations such as benchmarking of processes, identifying causes of process decay, selecting reference data sets for typicality studies, and reporting of historical data. Even those texts which cover retrospective analyses, usually ignore the question of identifying multiple points of change (breakpoints), and present essentially manual methods for assessing single breakpoints. Most users of statistical methods want software solutions that are easy to use and require little user intervention or interpretation. Direct implementation of manual method does not give a user robust solution. Problems are illustrated. Attempts to use monitoring CuSums in retrospective analysis can also lead to errors. A practical recursive method is presented for breakpoint identification and significance assessment, which can be automated. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

This study is an investigation of linkages between marital quality (conflict and harmony) and infants' emotional and physiological regulation: It was hypothesized that infants exposed to greater levels of marital conflict would demonstrate lower levels of emotional and physiological regulation. Fifty‐six low‐risk infants and their mothers attended a laboratory session when infants were 6 months of age. A baseline EKG was gathered to assess infants' cardiac vagal tone and the Bayley Scales of Infant Development and Behavior Rating Scales were administered. Mothers also completed Braiker and Kelley's (1979) marital quality questionnaire. Consistent with past research with preschoolers, marital conflict was found to be linked to lower levels of emotion regulation in infants. However, unlike past research (Gottman & Katz, 1989), results indicated that marital conflict was associated with lower levels of cardiac vagal tone in infants as opposed to higher levels of vagal tone among preschoolers. These findings are explained in terms of a possible developmental alteration in the link between marital conflict and vagal tone from early infancy to later childhood. Findings also have important implications for understanding the potential impact of the early marital relational context for infants emerging regulatory abilities.  相似文献
