Noncustodial Fathers’ Ability to Pay Child Support   总被引:3,自引:0,他引:3  
This article explores the extent to which noncustodial fathers can pay child support by estimating the income of noncustodial fathers and coupling these estimates with simulations of alternative normative standards for how much absent parents should be expected to contribute to the costs of rearing their children. The study indicates that the amount that is currently paid in child support ($6.8 billion in 1983) is far below the amount that should be paid under the various standards--from $24 billion to $29 billion.  相似文献

The aim of this investigation is to outline correlates of suicide ideation among LGBT individuals living in Nebraska. A community-based participatory research approach was utilized to develop a 30-minute, online anonymous survey. Almost half of the sample had seriously considered suicide at some point in their lives. Significant correlates of increased likelihood of suicide ideation are age, gender, transgender identity, income, depression, and discrimination. Suicide ideation is a serious concern for the health of LGBT Nebraskans. Steps should be taken to incorporate individuals who fall into these high-risk categories in suicide outreach programs.  相似文献

Our article utilizes variation across the 50 U.S. states to examine the relationship between public expenditures on children and child outcomes. We find that public expenditures on children are related to better child outcomes across a wide range of indicators including measures of child mortality, elementary school test scores, and adolescent behavioral outcomes. States that spend more on children have better child outcomes even after taking into account a number of potential confounding influences. Our results are robust to numerous variations in model specifications and to the inclusion of proxies for unobserved characteristics of states. Our sensitivity analyses suggest that the results we present may be conservative, yet our findings reveal a strong relationship between state generosity toward children and children's well-being.  相似文献

The fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) is being revised. A proposed revision hotly debated is to remove what is known as the exclusionary criterion and allow clinicians to diagnose a person with a major depressive episode within the early days and weeks following a death. The Executive Committee of the Association for Death Education and Counseling (ADEC) commissioned its Scientific Advisory Committee (SAC) to examine the debate over removing the exclusionary criterion and provide a written report. The DSM-IV-TR classifies bereavement as a clinical condition that is not a mental disorder. The exclusionary criterion states that within the first 2 months of the onset of bereavement a person should not be diagnosed as having major depression unless certain symptoms not characteristic of a normal grief reaction are present. We note these symptoms when discussing the exclusionary criterion. In the report we identify the features that comprise the exclusionary criterion, examine reasons (including research conclusions and clinical concerns) given for retaining and for eliminating the exclusionary criterion, offer extensive comments from experienced licensed clinicians about the issues involved, discuss diagnostic and treatment implications, and offer specific recommendations for ADEC to implement.  相似文献

Lay perceptions and experiences of social location have been commonly framed with reference to social class. However, complex responses to, and ambivalence over, class categories have raised interesting analytic questions relating to how sociological concepts are operationalized in empirical research. For example, prior researchers have argued that processes of class dis‐identification signify moral unease with the nature of classed inequalities, yet dis‐identification may also in part reflect a poor fit between ‘social class’ as a category and the ways in which people accord meaning to, and evaluate, their related experiences of socio‐economic inequality. Differently framed questions about social comparison, aligned more closely with people's own terms of reference, offer an interesting alternative avenue for exploring subjective experiences of inequality. This paper explores some of these questions through an analysis of new empirical data, generated in the context of recession. In the analysis reported here, class identification was common. Nevertheless, whether or not people self identified in class terms, class relevant issues were perceived and described in highly diverse ways, and lay views on class revealed it to be a very aggregated as well as multifaceted construct. It is argued that it enables a particular, not general, perspective on social comparison. The paper therefore goes on to examine how study participants compared themselves with familiar others, identified by themselves. The evidence illuminates social positioning in terms of constraint, agency and (for some) movement, and offers insight into very diverse experiences of inequality, through the comparisons that people made. Their comparisons are situated, and pragmatic, accounts of the material contexts in which people live their lives. Linked evaluations are circumscribed and strongly tied to these proximate material contexts.The paper draws out implications for theorizing lay perspectives on class, and subjective experiences of inequality.  相似文献

Over the last several years there has been increasing awareness of the connection between domestic violence and child abuse, yet only minimal attention has been paid to the implications of this for child protection practice. This article begins to address this gap. Drawing on research undertaken in New South Wales (NSW), Australia, it examines child protection practice in relation to children and young people who have been exposed to domestic violence. The research involved analysis of the responses of the statutory child protection authority in NSW (the Department of Community Services or DoCS) to abuse allegations involving domestic violence. The data are drawn from observation and analysis of the initial responses to referrals to DoCS and the ‘tracking’ of a sample of these referrals over an 18 month period. From the data obtained, it is evident that domestic violence referrals are treated less seriously than other referrals, with more being confirmed as abuse but fewer resulting in follow up or intervention. The implications of this for child protection practice are teased out. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Estimation and tests for serial correlation in recation and regression models with normal error have been derive from various points of view; for example: Anderson (1948), Durbi for Watson (1950, 1951, 1971), Theil (1965), Durbin (1970), Haq (1970), Kadiyala (1970), Abrahamse & Louter (1971), Levenbac (1972), Berenblut & Webb (1973), Phillips & Harvey (1974), a Sims (1975). In this paper we derive likelihood functions and most powerful tests for serial correclation in Locationa and regression models with arbitrary but specificed error; the methods extend to include the determination of the likelihood for the parameter of the error distribution.

In Section 2, we survey the modthods that have been used in deriving the various tests and estimates in the literature. In Section 2, we introduce the stataistical model that directly describes the error distribution and we obtain the likelihood function for error correlation and determine locally and specifically kost powerful tests for correlation. In Section 3 we consider the case with normal error derive a normal distribution on the sphere by radial projection. The likelihood function and test are then specialized to the case of normal error in Section 4. The computational procedures for the tests and related power functions are examined in Section 5. Power comparisons for the textile data of Theil and Nagar (1961), the consumption data of Kelin (1950), and the plums and the wheat data of Hildreth & Lu (1960) are presented in Section 6, while the likelihood functions for correlation in these data are given in Section 7.  相似文献

We use data from a new longitudinal survey – the Fragile Families and Child Wellbeing Study – to examine how welfare and child support policies, and local labor market conditions, affect union formation among unmarried parents who have just had a child together. We use multinomial logistic regression to estimate the effects of the policy variables along with economic, cultural/interpersonal, and other factors on whether (relative to being in a cohabiting relationship) parents are not romantically involved, romantically involved living apart, or married to each other about one year after the child's birth. We find that – contrary to some previous research – higher welfare benefits discourage couples from breaking up, while strong child support enforcement reduces the chances that unmarried parents will marry; local unemployment rates do not appear to be strongly associated with union formation decisions after a nonmarital birth.  相似文献
