Children’s educational attainment,occupation, and income and their parents’ mortality

Using data from Finland, this paper contributes to a small but growing body of research regarding adult children's education, occupation, and income and their parents' mortality at ages 50+ in 1970–2007. Higher levels of children's education are associated with 30–36 per cent lower parental mortality at ages 50–75, controlling for parents' education, occupation, and income. This association is fully mediated by children's occupation and income, except for cancer mortality. Having at least one child educated in healthcare is associated with 11–16 per cent lower all-cause mortality at ages 50–75, an association that is largely driven by mortality from cardiovascular diseases. Children's higher white-collar occupation and higher income is associated with 39–46 per cent lower mortality in the fully adjusted models. At ages 75+, these associations are much smaller overall and children's schooling remains more strongly associated with mortality than children's occupation or income.     

Almost Like a Real Band: Navigating a Gendered Jazz Art World

Professional jazz has been organized around two contradictory cultures. Historically, the jazz art world has followed norms of meritocracy, which promote equality across boundaries of race and class. At the same time a culture of exclusivity, anchored in gendered essentialism, has severely limited female participation. By analyzing interview data with artists from the Hamilton College Jazz Archive, we illustrate how these contradictory cultures of inclusion and exclusion operate to channel women into feminized roles in the jazz world. We then discuss how women employ a number of strategies to work around the culture of exclusivity and capitalize on the norms and values of musical meritocracy. Despite institutional openings in professional jazz that emerged following the women’s movement, female jazz artists continue to face strong barriers toward full equality in the jazz world. Although female artists consistently demonstrate that they possess equal musical skills to male musicians according to the norms of meritocracy that guide professional jazz, women remain on the margins of the jazz art world.     

Negotiating Symbolic Boundaries in Conflict Resolution: Religion and Ethnicity in Turkey’s Kurdish Conflict

This article is an inquiry into understanding why supranational religious identity often fails to act as a conflict resolution tool in religiously homogenous ethnic conflicts. Narrowing its focus down to the role of religious elites as potential peacemakers in such conflict zones, it proposes the divergence in their conceptualizations of religious and ethnic identities as an explanatory factor. Building on 62 in-depth interviews conducted in Turkey with Sunni Muslim Kurdish and Turkish religious elites, it identifies a three-fold typology of religious and ethnic identities, as conceptualized by these elites: 1) religio-ethnic; 2) ethno-religious; 3) religious. After exemplifying each category with interview data it demonstrates the role these distinctions play in preventing the successful implementation of “Muslim fraternity” as a solution to the Kurdish conflict in Turkey. With these findings, the article contributes to both the literature on religion in conflict resolution and that on identity formation and boundary making. While it invites the former to turn its gaze from macro-level structural factors to meso- and micro-level cultural factors in analyzing religious elite involvement in conflict resolution, it invites the latter to stop employing “ethnicity” as an all-encompassing term (that covers a vast array of identity markers including religion) and focus, instead, on the gradations between religion and ethnicity as sources of identity.     

The Influence of Career Planning on Career Thoughts in STEM‐Interested Undergraduates

Undergraduate career planning courses have shown efficacy in decreasing students’ negative career thoughts; however, universities have minimally applied these courses to science, technology, engineering, and math (STEM) populations. This study compared the influence of a STEM‐focused career planning course for undecided STEM students with a seminar course for decided STEM majors. An analysis of covariance with covariate adjustment revealed that undecided career planning students had lower adjusted mean scores on a measure of negative career thinking than the decided STEM majors after the first semester of college. The results provide support for the efficacy of STEM‐focused career planning courses and measuring negative career thoughts with STEM undergraduates.     

Integrated methodology for multiple systems estimation and record linkage using a missing data formulation

There are now three essentially separate literatures on the topics of multiple systems estimation, record linkage, and missing data. But in practice the three are intimately intertwined. For example, record linkage involving multiple data sources for human populations is often carried out with the expressed goal of developing a merged database for multiple system estimation (MSE). Similarly, one way to view both the record linkage and MSE problems is as ones involving the estimation of missing data. This presentation highlights the technical nature of these interrelationships and provides a preliminary effort at their integration.     

Consultants' forum: should post hoc sample size calculations be done?

Pre‐study sample size calculations for clinical trial research protocols are now mandatory. When an investigator is designing a study to compare the outcomes of an intervention, an essential step is the calculation of sample sizes that will allow a reasonable chance (power) of detecting a pre‐determined difference (effect size) in the outcome variable, at a given level of statistical significance. Frequently studies will recruit fewer patients than the initial pre‐study sample size calculation suggested. Investigators are faced with the fact that their study may be inadequately powered to detect the pre‐specified treatment effect and the statistical analysis of the collected outcome data may or may not report a statistically significant result. If the data produces a “non‐statistically significant result” then investigators are frequently tempted to ask the question “Given the actual final study size, what is the power of the study, now, to detect a treatment effect or difference?” The aim of this article is to debate whether or not it is desirable to answer this question and to undertake a power calculation, after the data have been collected and analysed.

A copula-based Markov chain model for the analysis of binary longitudinal data

A fully parametric first-order autoregressive (AR(1)) model is proposed to analyse binary longitudinal data. By using a discretized version of a copula, the modelling approach allows one to construct separate models for the marginal response and for the dependence between adjacent responses. In particular, the transition model that is focused on discretizes the Gaussian copula in such a way that the marginal is a Bernoulli distribution. A probit link is used to take into account concomitant information in the behaviour of the underlying marginal distribution. Fixed and time-varying covariates can be included in the model. The method is simple and is a natural extension of the AR(1) model for Gaussian series. Since the approach put forward is likelihood-based, it allows interpretations and inferences to be made that are not possible with semi-parametric approaches such as those based on generalized estimating equations. Data from a study designed to reduce the exposure of children to the sun are used to illustrate the methods.     

A re-evaluation of random-effects meta-analysis

Summary.  Meta-analysis in the presence of unexplained heterogeneity is frequently undertaken by using a random-effects model, in which the effects underlying different studies are assumed to be drawn from a normal distribution. Here we discuss the justification and interpretation of such models, by addressing in turn the aims of estimation, prediction and hypothesis testing. A particular issue that we consider is the distinction between inference on the mean of the random-effects distribution and inference on the whole distribution. We suggest that random-effects meta-analyses as currently conducted often fail to provide the key results, and we investigate the extent to which distribution-free, classical and Bayesian approaches can provide satisfactory methods. We conclude that the Bayesian approach has the advantage of naturally allowing for full uncertainty, especially for prediction. However, it is not without problems, including computational intensity and sensitivity to a priori judgements. We propose a simple prediction interval for classical meta-analysis and offer extensions to standard practice of Bayesian meta-analysis, making use of an example of studies of 'set shifting' ability in people with eating disorders.     

In search of career satisfaction: African-American public relations practitioners, pigeonholing, and the workplace

The goals of the research were to explore African-American practitioners’ satisfaction with public relations as a career and to examine their perceptions of tokenism and pigeonholing in the workplace. Three key themes emerged from the research: career entry and social support in public relations; encounters with everyday racism; and pigeonholing in public relations. For the majority of 12 African-American practitioners interviewed, they have experienced discrimination in their careers and in public relations, yet the practitioners did not see themselves as pigeonholed in their roles or positions.

The meaning of frailty according to Dutch older frail and non-frail persons

Frailty is a term often used by researchers and clinicians to describe a state in which older persons are at risk for adverse outcomes such as falls, disability, institutionalization and mortality. However, no study so far examined what frailty means to older persons. Therefore the aim of this study was to describe the meaning that older community-dwelling persons attach to frailty. Twenty-five semi-structured interviews were conducted. The interviews were analyzed using the grounded theory method. Frailty was described as being in poor health, having walking difficulties, feeling down, being anxious, having few social contacts and not being able to do the things one likes to do. Men described in more detail the physical dimension whereas women elaborated in more depth on the psychological and social component. Existing definitions of frailty should be adjusted to better reflect the meaning of frailty for older persons.
