A reconsideration of the economic consequences of marital dissolution

A close look at the income flows in the years following a divorce or separation reveals marked differences in the distribution of effects. The economic consequences of divorce are especially adverse for women. In most cases, children remain with the mother, who usually has considerably lower potential labor market earnings than her former husband, partly because her responsibilities for the children are likely to reduce her labor supply and may have limited her past human capital investments. Alimony and child support are the principal mechanisms for transfers from the ex-husband to the ex-wife, but payments are rarely frequent or sizeable enough to make up for an appreciable amount of the labor income lost through the departure of the ex-husband. Human capital investments on the part of the mother have a modest effect on her economic situation in the years following the divorce. Most men who divorce or separate are immediately better off because they retain most of their labor incomes, typically do not pay large amounts of alimony and child support to their ex-wives, and no longer have to provide for the level of needs associated with their former families. Much more important than growth in the ex-wife's own labor income is the role of a new husband's labor income upon her remarriage. More than half of the white women remarry within five years following a divorce or separation; the comparable fraction for black women is less than half. An interesting question is whether the currently unmarried would enjoy the same kind of economic benefits, were they to remarry, as women who have remarried. Estimates from a model of the new husband's labor income, adjusted for selection bias inherent in the process of remarriage, indicate that the currently unmarried would probably not gain equal benefits if they were to remarry. The expected labor income of potential husbands of black women averages only about $5000--a modest amount when compared with the alternatives available to these women.     

A Ecological Model of Well-Being in Child Welfare Referred Children

Despite its social, political and economic relevance, child well-being remains a challenging construct to define and measure accurately. This holds true especially for children growing up in at-risk families, where their development is hindered by many adverse circumstances. Typically, the well-being of child welfare (CW) referred children has been conceptualized as the absence of negative outcomes, and the study of its determinants has been limited to children’s micro-systems. In this study, we aimed to obtain a suitable indicator of child well-being and to test a model of the determinants of CW referred children’s well-being including parental, family and wider contextual variables. The sample included 249 parents and 46 case managers from Portuguese and Spanish CW services. A three-domain solution from selected items of the Child Well-Being Scales (Physical, Academic and Socioemotional) was tested and confirmed through Confirmatory Factor Analysis. The results of structural equation modeling for each domain revealed that risk factors nested in the wider context and those related to material disadvantage were the most powerful predictors of physical well-being, while parenting and family functioning variables predicted better both academic and socio-emotional well-being. Our findings suggest that different risk and protective factors matter for different outcomes and that most of these factors are associated with each other. Therefore, interventions with at-risk children must take this specificity into account when targeting each domain of well-being, and efforts could be allocated to a few modifiable dimensions, which would in turn positively affect other parental and family factors.     

No time to worship the serpent deities: women,economic change,and religion in north-western Nepal

This paper explores the changing relationships between lay women, and the spiritual realm, in two ethnic Tibetan communities, Kag and Dzong, in northwestern Nepal. The study tackles how economic and social change has affected women's spiritual roles within the household and the community, and how these roles, in turn, have influenced the course of such change. In Kag, the introduction of tourism changed women's way of life. They became income-generating members of the community as lodge-owners. With new responsibilities to manage, Kag women eventually neglected their traditional social and spiritual obligations, much to the dismay of the older generation. On the other hand, women in Dzong still consider full social and physical participation in village life important despite the added obligations. They maintain spiritual harmony within the village. Dzongba women do not seem to feel the same conflicts as Kagpa women. The negative impact of Kag women's neglect of traditional social and spiritual responsibilities should be weighed against the possible benefits to women, household, and economy.     

Marital instability and the economic status of women

This paper uses longitudinal data from the Panel Study of Income Dynamics to examine the relationship between changes in marital status and economic status. Differences between men and women and between whites and blacks are also considered. A major finding is that, after adjusting for changes in family size, the economic status of divorced or separated men improves, while that of women declines. Components of income change are discussed, with special emphasis on changes in the labor force and welfare status of women who were divorced or separated during the analysis period. Finally, data on the magnitude and distribution of alimony/child-support payments are presented.     

Enabling Adults with Learning Disabilities to Articulate their Housing Needs

Correspondence to Dr Alex McGlaughlin, Department of Social Sciences, The Nottingham Trent University, Burton Street, Nottingham NG1 4BU, UK. E-mail: alex.mcglaughlin{at} ntu.ac.uk Summary This study is about involving adults with learning disabilitiesin service planning by asking them to articulate their own needsin relation to housing. It also identifies some of the barriersto meeting the housing needs of this group. The views expressedindicate that ordinary housing with small numbers is the preference,and that appropriate support is highly valued. This suggestsa need for housing of a supported living model or similar. Theservice users in this study were clearly able to verbalize theirpreferences as well as to think through potential options. However,there is also clear evidence that they feel powerless in makingchoices, with decisions being taken on their behalf by professionalsand carers. This demonstrates the need for a cultural shiftwhereby the voices of adults with learning disabilities areheard and acted upon.     

A TWO STAGE PROCEDURE FOR ESTIMATING THE SIZE OF A TRUNCATED EXPONENTIAL SAMPLE

Let X₁, …, X_N be i.i.d. exponential random variables with unknown scale parameter θ. If one can observe only those X_i in (0, T₀), an estimate of N based on the J observations obtained has a variance which explodes as θ→θC. Using θC based on the observations in (0, T₀) T is computed and all X_i in (0, ) are observed. An estimate of N based on all observations in (0, ) has a bounded variance where the bound can be adjusted by proper choice of .     

Time-varying coefficient cumulative gap time models for intensive longitudinal ecological momentary assessment data with missingness

Ecological momentary assessment (EMA) studies investigate intensive repeated observations of the current behavior and experiences of subjects in real time. In particular, such studies aim to minimize recall bias and maximize ecological validity, thereby strengthening the investigation and inference of microprocesses that influence behavior in real-world contexts by gathering intensive information on the temporal patterning of behavior of study subjects. Throughout this paper, we focus on the data analysis of an EMA study that examined behavior of intermittent smokers (ITS). Specifically, we sought to explore the pattern of clustered smoking behavior of ITS, or smoking ‘bouts’, as well as the covariates that predict such smoking behavior. To do this, in this paper we introduce a framework for characterizing the temporal behavior of ITS via the functions of event gap time to distinguish the smoking bouts. We used the time-varying coefficient models for the cumulative log gap time and to characterize the temporal patterns of smoking behavior, while simultaneously adjusting for behavioral covariates, and incorporated the inverse probability weighting into the models to accommodate missing data. Simulation studies showed that irrespective of whether missing by design or missing at random, the model was able to reliably determine prespecified time-varying functional forms of a given covariate coefficient, provided the the within-subject level was small.     

An assessment of the statistical methods used to analyse toxicology studies

The Statisticians in the Pharmaceutical Industry Toxicology Special Interest Group has collated and compared statistical analysis methods for a number of toxicology study types including general toxicology, genetic toxicology, safety pharmacology and carcinogenicity. In this paper, we present the study design, experimental units and analysis methods.     

Review of the statistical analysis of the dog telemetry study

In 2008, the PSI Toxicology Special Interest Group met to discuss the design and analysis of dog telemetry studies. The dog telemetry study is one component of the integrated cardiovascular assessment required by regulatory bodies. Although there are guidelines for these studies, little is said about the statistical analysis. With parameters of interest measured continually over time, in studies typically involving four dogs, the analysis is not straightforward. This has led to many different types of analysis being proposed in the literature, with many different methods applied within the pharmaceutical industry itself. This paper summarizes the PSI Toxicology group's discussions and recommendations around these issues.
