Advances in Families and Health Research in the 21st Century

We review research on families and health published between 2000 and 2009 and highlight key themes and findings from innovative, methodologically rigorous studies. Whereas research in prior decades focused primarily on whether family structure affects child and adult health, contemporary research examines the contextual and processual factors that shape for whom, for which outcomes, and under what conditions families affect mental and physical health. We discuss how family structure, transitions, and processes within families of origin affect children's health over the life course. We then examine the effects of marital status, transitions, and quality for adult health. We point out limitations in current research, discuss implications of recent findings for policy, and highlight theoretical and methodological directions for future research.     

Modeling individual migraine severity with autoregressive ordered probit models

This paper considers the problem of modeling migraine severity assessments and their dependence on weather and time characteristics. We take on the viewpoint of a patient who is interested in an individual migraine management strategy. Since factors influencing migraine can differ between patients in number and magnitude, we show how a patient’s headache calendar reporting the severity measurements on an ordinal scale can be used to determine the dominating factors for this special patient. One also has to account for dependencies among the measurements. For this the autoregressive ordinal probit (AOP) model of Müller and Czado (J Comput Graph Stat 14: 320–338, 2005) is utilized and fitted to a single patient’s migraine data by a grouped move multigrid Monte Carlo (GM-MGMC) Gibbs sampler. Initially, covariates are selected using proportional odds models. Model fit and model comparison are discussed. A comparison with proportional odds specifications shows that the AOP models are preferred.     

Happy People Have Children: Choice and Self-Selection into Parenthood

There is mixed evidence in the existing literature on whether children are associated with greater subjective well-being, with the correlation depending on which countries and populations are considered. We here provide a systematic analysis of this question based on three different datasets: two cross-national and one national panel. We show that the association between children and subjective well-being is positive only in developed countries, and for those who become parents after the age of 30 and who have higher income. We also provide evidence of a positive selection into parenthood, whereby happier individuals are more likely to have children.     

Pair‐copula constructions for non‐Gaussian DAG models

We propose a new type of multivariate statistical model that permits non‐Gaussian distributions as well as the inclusion of conditional independence assumptions specified by a directed acyclic graph. These models feature a specific factorisation of the likelihood that is based on pair‐copula constructions and hence involves only univariate distributions and bivariate copulas, of which some may be conditional. We demonstrate maximum‐likelihood estimation of the parameters of such models and compare them to various competing models from the literature. A simulation study investigates the effects of model misspecification and highlights the need for non‐Gaussian conditional independence models. The proposed methods are finally applied to modeling financial return data. The Canadian Journal of Statistics 40: 86–109; 2012 © 2012 Statistical Society of Canada     

Seeing beyond the datasets: the unexploited structure of electoral and institutional data

We propose relational data modeling as a tool for replacing the ad hoc and uncoordinated approaches commonly used throughout the social sciences to gather, store, and disseminate data. We demonstrate relational data modeling using global electoral and political institutional data. We define a relational data model as a map of concepts, their attributes, and the relationships between concepts developed using a formal language and according to a set of rules. To demonstrate the methodology, we design a simple relational data model of six concepts: countries, parties, elections, districts, institutions, and election results. Furthermore, we introduce a data model to solve the particularly vexing issue of party discontinuity (party splits, mergers, and alliances). We show how the solution facilitates computational tasks, such as the calculation of core measures of political phenomena (ex: electoral volatility). Ultimately, a relational data approach will play a central role in collective investments to develop advanced data capabilities, and thereby advance the accuracy, pace, and transparency of scholarship in the social sciences.     

An Exploration of the Construction of Commitment Leading to Marriage

The purpose of this qualitative study was to explore how newly married couples construct and reconstruct commitment through events in courtship and early marriage. Fifteen newly married couples, 30 participants, were interviewed individually. Through the use of grounded theory six different themes (friendship, gradual process, positive examples, negative examples, planning for the future, and words of affirmation) emerged in the construction, origination, and communication of commitment. The results of this study have specific implications for theory, research, and practice with young adult couples. The concept of resilient commitment is introduced and briefly discussed.     

Initiating Senior Co-Housing: People,Place, andLong-Term Security

Abstract

An increasing proportion of older people are unable to afford rental or purchase of age-appropriate residential accommodation in Australia. This article reports on a community-initiated research project investigating feasibility of affordable co-housing for older residents wishing to age in their community. Factors enabling successful co-housing for seniors were investigated through a systematic literature review. The multiphase participatory research approach drew on the knowledge of local seniors, community support workers, and planning and design professionals through workshops and interviews in a regional community in southeast Queensland. The findings demonstrate interest in and barriers to senior co-housing. The research engagement approach enables tailored solutions for individual long-term security, relevant to small communities in Australia.     

Joint decisions on household membership and human capital accumulation of youths. The role of expected earnings and local markets

This paper analyses the effects of expected earnings and local markets conditions on the behaviour of young adults with high school diplomas. Decisions to either remain in the parental home or form a new household are modelled jointly with those of either gaining work experience or investing in a university education. Expected lifetime earnings are found to play a crucial role in determining the choice of studying and residing with parents. Poor labour market opportunities discourage young people from working and induce them to study. The cost of housing greatly influences the choice of working and leaving the parental home.

"Macho men" and preventive health care: implications for older men in different social classes

The gender paradox in mortality--where men die earlier than women despite having more socioeconomic resources--may be partly explained by men's lower levels of preventive health care. Stereotypical notions of masculinity reduce preventive health care; however, the relationship between masculinity, socioeconomic status (SES), and preventive health care is unknown. Using the Wisconsin Longitudinal Study, the authors conduct a population-based assessment of masculinity beliefs and preventive health care, including whether these relationships vary by SES. The results show that men with strong masculinity beliefs are half as likely as men with more moderate masculinity beliefs to receive preventive care. Furthermore, in contrast to the well-established SES gradient in health, men with strong masculinity beliefs do not benefit from higher education and their probability of obtaining preventive health care decreases as their occupational status, wealth, and/or income increases. Masculinity may be a partial explanation for the paradox of men's lower life expectancy, despite their higher SES.
