On A Method for Studying Family Size Preferences

Demography - The concept of desired family size is widely accepted, and numerous studies have been undertaken to measure its level in certain population groups. The determination of desired family...     

‘Book don’t feed our children’: Nonconformist missionaries and the British and Foreign School Society in the development of elementary education in the British West Indies before and after emancipation

This study examines the ways in which Nonconformist missionaries joined with the British and Foreign School Society (BFSS) to provide elementary instruction to enslaved and emancipated children in the nineteenth-century British West Indies. Using predominantly untapped historical sources from the BFSS archive’s newly catalogued West Indian collection, this article seeks to address a long-standing historiographic gap regarding the pedagogic methods and practices employed by Nonconformist missionaries in the British Caribbean. In so doing, it highlights the combined impact that local conditions and global currents of missionary and educational fervour had on establishing an effective elementary system during the emancipation era.     

A systematic literature review of the relationship between work hours and sickness absence

The aim of this study was to determine the relationship between work hours and sickness absence: is a higher number of work hours associated with better or with adverse health? A systematic literature review was performed by searching Medline, PsychInfo, and Web of Science. All abstracts were screened to identify papers that empirically investigated the relationship between work hours and sickness absence in a working population. A total of 1072 papers were identified, and 70 papers were included in this review. A simple measure of the strength of effects was applied, and the findings are summarised in narrative form. Evidence supporting a relationship between sickness absence and working part-time or work hours as a continuous variable was inconclusive. These inconclusive findings might be due to heterogeneity in the operationalisation of key variables or to publication bias. Support for a negative relationship between long work hours and sickness absence was moderately strong. Possible explanations for this include the healthy worker selection effect, differences in job characteristics, and differences in job motivation. Empirical testing of these explanations, however, has been limited. Our findings indicate that employers should monitor employee health in times of high work pressure, even if sickness absence is low.     

Evaluation of alternative confidence intervals to address non-inferiority through the stratified difference between proportions

The confidence interval (CI) for the difference between two proportions has been an important and active research topic, especially in the context of non-inferiority hypothesis testing. Issues concerning the Type 1 error rate, power, coverage rate and aberrations have been extensively studied for non-stratified cases. However, stratified confidence intervals are frequently used in non-inferiority trials and similar settings. In this paper, several methods for stratified confidence intervals for the difference between two proportions, including existing methods and novel extensions from unstratified CIs, are evaluated across different scenarios. When sparsity across the strata is not a concern, adding imputed observations to the stratification analysis can strengthen Type-1 error control without substantial loss of power. When sparseness of data is a concern, most of the evaluated methods fail to control Type-1 error; the modified stratified t-test CI is an exception. We recommend the modified stratified t-test CI as the most useful and flexible method across the respective scenarios; the modified stratified Wald CI may be useful in settings where sparsity is unlikely. These findings substantially contribute to the application of stratified CIs for non-inferiority testing of differences between two proportions.     

Body art,deviance, and American college students

This research examines the relationship between body art (tattoos and piercings) and deviance. With the increasing mainstream presence of visible tattoos and piercings among entertainers, athletes, and even in corporate boardrooms, we wonder the extent to which long-time enthusiasts and collectors regard the phenomenon as encroachment. We use sub-cultural identity theory to propose that individuals with increasing evidence of body art procurement will also report higher levels of deviant behavior in order to maintain and/or increase social distance from the mainstream. We tested this proposition by surveying 1753 American college students, asking them to report their level of body art acquisition and their history of deviance. Results indicate that respondents with four or more tattoos, seven or more body piercings, or piercings located in their nipples or genitals, were substantively and significantly more likely to report regular marijuana use, occasional use of other illegal drugs, and a history of being arrested for a crime. Less pronounced, but still significant in many cases, was an increased propensity for those with higher incidence of body art to cheat on college work, binge drink, and report having had multiple sex partners in the course of their lifetime.     

Utilizing research in professional practice

A review of the rehabilitation, disability studies, and allied health literature suggests the presence of numerous factors that impede the utilization of research by practitioners. The purpose of this article is to describe these factors and offer potential solutions that could enable rehabilitation professionals to integrate research findings into their practice. Specifically, the authors recommend strategies to (a) contextualize research throughout pre-service curricula, (b) establish researcher-stakeholder partnerships, (c) increase the accessibility of research to practitioners, and (d) establish professional and peer support for implementing research in field practice.     

Dependence maps: Local dependence in practice

There is often more structure in the way two random variables are associated than a single scalar dependence measure, such as correlation, can reflect. Local dependence functions such as that of Holland and Wang (1987) are, therefore, useful. However, it can be argued that estimated local dependence functions convey information that is too detailed to be easily interpretable. We seek to remedy this difficulty, and hence make local dependence a more readily interpretable practical tool, by introducing dependence maps. Via local permutation testing, dependence maps simplify the estimated local dependence structure between two variables by identifying regions of (significant) positive, (not significant) zero and (significant) negative local dependence. When viewed in conjunction with an estimate of the joint density, a comprehensive picture of the joint behaviour of the variables is provided. A little theory, many implementational details and several examples are given.     

Representations of Attachment to Father in the Narratives of Preschool Girls in Post-Divorce Families: Implications for Family Relationships and Social Development

This study used the Attachment Story Completion Task-Revised (ASCT-R) (Bretherton, Ridgeway, & Cassidy, 1990), a representational measure of attachment security, to examine characteristics of preschool-aged girls' narratives associated with portrayals of attachment to the father. The children's (n = 27) parents had been divorced or legally separated for at least 2 years, and they lived in the primary custody of their mothers. We had previously discovered that girls' responses to the ASCT-R differed from those of boys in unexpected ways. Whereas boys' representations of child-father attachment varied positively with teacher ratings of social behavior in child-care settings, the opposite was the case for girls. Girls who portrayed children's attachment to the father more frequently were rated lower in social competence, contrary to expectations. A more detailed analysis of responses to the ASCT-R suggests that girls' representational attachment behavior toward the father was associated with narrative representations of both parents as unavailable, family instability, and concerns for the father's well-being.
