Mixed-Poisson Point Process with Partially-Observed Covariates: Ecological Momentary Assessment of Smoking

Ecological Momentary Assessment is an emerging method of data collection in behavioral research that may be used to capture the times of repeated behavioral events on electronic devices, and information on subjects' psychological states through the electronic administration of questionnaires at times selected from a probability-based design as well as the event times. A method for fitting a mixed Poisson point process model is proposed for the impact of partially-observed, time-varying covariates on the timing of repeated behavioral events. A random frailty is included in the point-process intensity to describe variation among subjects in baseline rates of event occurrence. Covariate coefficients are estimated using estimating equations constructed by replacing the integrated intensity in the Poisson score equations with a design-unbiased estimator. An estimator is also proposed for the variance of the random frailties. Our estimators are robust in the sense that no model assumptions are made regarding the distribution of the time-varying covariates or the distribution of the random effects. However, subject effects are estimated under gamma frailties using an approximate hierarchical likelihood. The proposed approach is illustrated using smoking data.     

Sexual-moral attitudes, love styles, and mate selection

Students at a southwestern university were surveyed to test the interrelations of three constructs: sexual-moral attitudes, love styles, and attraction criteria. Following the procedures of the National Health and Social Life Survey, from which the sexual-moral attitude items were obtained, we conducted a cluster analysis to create attitudinal groupings. We obtained four clusters representing various nuances of liberalism and conservatism. When compared on love styles, the clusters differed primarily on ludus and pragma. Not only did some of the liberal clusters differ from some of the conservative ones on love styles, but there were also some differences within liberalism and within conservatism. Cluster differences also emerged on the attraction criteria.     

Gay Seouls: Expanding Religious Spaces for Non-Heterosexuals in South Korea

What Protestant congregations offer spaces for worship and dialogue among persons with different sexual orientations? The academic literature finds or assumes that non-heterosexuals are stigmatized or invisible in theologically conservative congregations and are welcomed in progressive, affirming congregations. This article develops an alternative claim that some conservative or evangelical congregations offer attractive spaces for non-heterosexuals to worship and dialogue. We illustrate with an exploratory study of four congregations in South Korea—two theologically progressive, two evangelical—whose pastors welcomed everybody regardless of sexual orientation or gender identity. The “inclusive-evangelical” congregations retained conservative theology on sexuality (sexual relations only within heterosexual marriage) but offered more empathic dialogue with non-heterosexuals than did most evangelical congregations; they also provided more resources, conventional religious culture, and ties to traditional affective networks than the affirming-progressive congregations. Inclusive-evangelical congregations offer an institutional venue for non-heterosexual Christians in Korea to potentially reconcile three central values: conservative Christianity, traditional (Confucian) affective networks, and expressive individualism.     

A cross-national and comparative classification of in-country awareness and policy responses to ‘young carers’

The reality for many families where there is chronic illness, mental health problems, disability, alcohol or substance misuse is that children under the age of 18 are involved in caring. Many of these children – known as ‘young carers’ – will be providing regular and significant care, either episodically or over many years, often ‘hidden’ to health, social care and other welfare professionals and services. These children have most often been invisible in social policy and professional practice. What are the reasons why some countries recognize young carers as a priority for social policy while others (most) do not? What are the key factors that influence a country’s awareness and responses to these children? This article provides an original classification and analysis of country-level responses to young carers, drawing on published research, grey literature, policy documents and the authors’ extensive engagement in policy and practice networks for young carers and their families in a wide range of countries. The analysis identifies two of the key factors that influence the extent and nature of these policy responses, focusing on the importance of a reliable in-country research base and the contribution of influential national NGOs and their networks.     

Welfare benefits,economic opportunities,and out-of-wedlock births among black teenage girls

This article presents a model of teenage out-of-wedlock births that incorporates the effects of both welfare and nonwelfare economic opportunities. We construct measures of the likely "medium-run" income available to a teenage girl in the event of an out-of-wedlock birth and in the absence of a birth and then estimate a logit model to determine their importance in influencing fertility behavior. The model is estimated with data from the Panel Study of Income Dynamics on nearly 900 black teenagers. We find weak and statistically insignificant positive effects of Aid to Families With Dependent Children (AFDC) benefit levels and stronger and significant negative effects of economic opportunities on the probability of AFDC-related out-of-wedlock teen births.     

What are the economic consequences of divorce?

Our analysis suggests that Weitzman's finding concerning the precipitous decline in the economic status of women following divorce is likely to be incorrect. Her findings not only imply improbably large changes in income but are also inconsistent with the information she reports on changes in income and in income per capita. Corrected estimates suggest a decline in economic status of about one-third, rather than the widely cited 73 percent figure. It remains the case that the economic status of men and women diverge substantially in the years after divorce. That difference, however, is not nearly as dramatic as suggested by Weitzman's findings.
