Using data augmentation to correct for non-ignorable non-response when surrogate data are available: an application to the distribution of hourly pay

Summary.  The paper develops a data augmentation method to estimate the distribution function of a variable, which is partially observed, under a non-ignorable missing data mechanism, and where surrogate data are available. An application to the estimation of hourly pay distributions using UK Labour Force Survey data provides the main motivation. In addition to considering a standard parametric data augmentation method, we consider the use of hot deck imputation methods as part of the data augmentation procedure to improve the robustness of the method. The method proposed is compared with standard methods that are based on an ignorable missing data mechanism, both in a simulation study and in the Labour Force Survey application. The focus is on reducing bias in point estimation, but variance estimation using multiple imputation is also considered briefly.     

A jackknife variance estimator for unequal probability sampling

Summary.  The jackknife method is often used for variance estimation in sample surveys but has only been developed for a limited class of sampling designs. We propose a jackknife variance estimator which is defined for any without-replacement unequal probability sampling design. We demonstrate design consistency of this estimator for a broad class of point estimators. A Monte Carlo study shows how the proposed estimator may improve on existing estimators.     

Effects of Commitment and Psychological Centrality on Fathering

Propositions from identity theory suggest that interactional and affective commitment to a role identity affects the psychological centrality of that role identity. In turn, the centrality of one's role identity translates into role performance ( Stryker & Serpe, 1994 ). This conceptual model was tested with a sample of 186 fathers in first marriages with at least one child 18 years or younger. The results showed that fathers who perceived their wives as evaluating them positively as fathers were more likely to report higher levels of involvement in child‐related activities and place greater importance on the father role identity. This prominence, in turn, was associated with higher levels of involvement.     

Variance estimation for a low income proportion

Summary. Proportions below a given fraction of a quantile of an income distribution are often estimated from survey data in comparisons of poverty. We consider the estimation of the variance of such a proportion, estimated from Family Expenditure Survey data. We show how a linearization method of variance estimation may be applied to this proportion, allowing for the effects of both a complex sampling design and weighting by a raking method to population controls. We show that, for data for 1998–1999, the estimated variances are always increased when allowance is made for the design and raking weights, the principal effect arising from the design. We also study the properties of a simplified variance estimator and discuss extensions to a wider class of poverty measures.     

Combining Dyslexia and Mothering: Perceived Impacts on Work

Previous studies have provided an insight into the lives of disabled mothers, but little attention has been paid to disabled working mothers. This paper draws on interviews with women who had a formal diagnosis of dyslexia, to discuss: particular difficulties when combining work and mothering; the perceived positive impacts on work and education, of becoming a mother; unsupportive managers; what some mothers found helpful in order to maintain work; and the diversity between experiences. We conclude that for those already on a career path before having children, some of their experiences could have been seen as an amplification of what other working mothers face. However, a difference was that the added time taken up with mothering meant they became more vulnerable to ‘exposing’ their impairment at work. In contrast, for dyslexic women who were yet to attain a high status in education and work, motherhood encouraged them to initiate their career.     

Minimal Treatment Approaches for Concerned Significant Others of Problem Gamblers: A Randomized Controlled Trial

The goal of this study was to examine the efficacy of minimal treatment interventions for concerned significant others (CSOs) of problem gamblers. One hundred and eighty-six participants (82% females, 56% spouses) were randomly assigned to one of three groups: the first minimal intervention group received a self-help workbook [based on behavioral principles, modified from the Community Reinforcement and Family Therapy (CRAFT) model] and the second minimal intervention group received the workbook plus telephone support. The control condition received a treatment resource information package. Overall, all participants reported significant improvement in personal and relationship functioning and gambling behavior and consequences at the 3- and 6-month follow-up. The data demonstrated differences in favor of the interventions in three areas: days gambling, satisfaction with the program, and number who had their needs met. There was no difference in the number who had entered treatment. It may be that CSOs require more guidance and follow-up support to achieve these goals using the CRAFT procedures and strategies.     

The Developmental Progression of Understanding of Mind during a Hiding Game

In this longitudinal study, 52 typically developing preschoolers engaged in a hiding game with their mothers when children were 42‐, 54‐, and 66‐months old. Children's understanding of mind, positive affect, and engagement with the task were rated, and mothers' utterances were coded for role and content. Analyses confirmed that some facets of children's understanding of mind developed sequentially; specifically, they expressed an understanding of knowledge access before an understanding of deception and false beliefs, and expressed an understanding of deception before an understanding of false beliefs. Children's understanding of mind increased across visits and positively correlated with false belief task performance. Results suggest that mothers may tailor the content of their utterances to the child's growing expertise, but the role of mothers' utterances did not change. Observing preschoolers engaged in a playful hiding game revealed that children's understanding of mind not only increased with age but also developed sequentially.     

The Government Communication Decision Wheel: Toward a Public Relations Model for the Public Sector

We argue that the existing public relations and communication models do not adequately account for the unique environmental characteristics of the public sector. By reviewing the public sector environment literature, we identify 8 attributes that affect government public relations: politics, focus on serving the public, legal constraints, extreme media and public scrutiny, lack of managerial support for public relations practitioners, poor public perception of government communication, lagging professional development, and federalism. We then review 5 existing public relations models, arguing that none of these models fully incorporates the unique environmental characteristics of the public sector. We conclude by proposing a new model: the government communication decision wheel.     

What makes leadership,leadership? Using self-expansion theory to integrate traditional and contemporary approaches

Numerous traditional theories and paradigms of leadership purport to describe what leadership is. It is difficult to reconcile these traditional approaches, however, if each one alone, independent of the others, is viewed as capturing the actual identity of leadership. In this article, we take an integrative view of traditional approaches to leadership. To do so, we first identify some underlying ideas common to them. Next, we explain how these underlying ideas lead us to a fundamental theory about close relationships—that is, self-expansion theory, which refers to a psychological process in which an individual incorporates another into the self (Aron & Aron, 1986). We then review the traditional leadership theories to explore whether these theories may be linked through self-expansion theory and whether self-expansion may help to explain why boundary conditions have been discovered for all of them. In this process, we explore whether traditional approaches to leadership might also be linked with more contemporary approaches through self-expansion theory. Finally, we discuss the implications for future research and professional practice of the integration of traditional approaches to leadership.
