Noninformative priors for the common mean in the bivariate normal distribution

In this paper, we consider some noninformative priors for the common mean in a bivariate normal population. We develop the first-order and second-order matching priors and reference priors. We find that the second-order matching prior is also an HPD matching prior, and matches the alternative coverage probabilities up to the second order. It turns out that derived reference priors do not satisfy a second-order matching criterion. Our simulation study indicates that the second-order matching prior performs better than the reference priors in terms of matching the target coverage probabilities in a frequentist sense. We also illustrate our results using real data.     

Reliability acceptance sampling plans for the Weibull distribution under accelerated Type-I censoring

Type-I censored reliability acceptance sampling plans (RASPs) are developed for the Weibull lifetime distribution with unknown shape and scale parameters such that the producer and consumer risks are satisfied. It is assumed that the life test is conducted at an accelerated condition for which the acceleration factor (AF) is known, and each item is continuously monitored for failure. Sensitivity analyses are also conducted to assess the effect of the uncertainty in the assumed AF on the actual producer and consumer risks, and a method is developed for constructing RASPs that can accommodate the uncertainty in AF.     

Bayesian partial likelihood approach for tied observations

The Bayesian analysis based on the partial likelihood for Cox's proportional hazards model is frequently used because of its simplicity. The Bayesian partial likelihood approach is often justified by showing that it approximates the full Bayesian posterior of the regression coefficients with a diffuse prior on the baseline hazard function. This, however, may not be appropriate when ties exist among uncensored observations. In that case, the full Bayesian and Bayesian partial likelihood posteriors can be much different. In this paper, we propose a new Bayesian partial likelihood approach for many tied observations and justify its use.     

How student teachers (don’t) talk about race: An intersectional analysis

This study explores how student teacher talk about their students illuminates the identities ascribed to these same students. It uses a hybrid intersectional framework based on Disability Studies, Critical Race Theory, and Latino Critical Theory and methodologies (like examining majoritarian stories, counter-storytelling, coded talk, and post-civil rights race talk) to uncover how student teacher talk reveals oppressive discourses of race, disability (and language status). This article focuses on how the medicalization of disability facilitates student teachers not identifying the racialization of disability in school. It demonstrates the need for educational research to employ an intersectionality lens when exploring educational issues related to students’ identities.     

Declining inter-industry wage dispersion in the US

Industrial effects have long been significant factors in wage inequality. Previous research indicates that wage differentials across industries were increasing through the mid 1980s. Using more recent data, however, we find that the level of inter-industry wage dispersion declined by 36% from 1986 to 2002 despite the continued trend towards increasing inequality in the labor force. This decline in inter-industry wage dispersion is evident across gender and educational groups. Using multilevel growth curve models, our multivariate results indicate that the decline is only weakly related to industrial changes in education, occupation or even productivity despite the fact that the latter variable had been a critical factor in the prior period. Indicators of globalization and downsizing also do not appear to explain this decline. For the more recent period, the most important factors associated with the narrowing of inter-industry wage dispersion are reduced unionization rates and the higher proportion of casual workers. We interpret these results as suggesting that firms may now be less economically obliged to pass on a portion of their rents to broad groups of workers and may instead be engaged in more idiosyncratic processes of negotiation with individual workers based on micro-level sources of bargaining power.     

A longitudinal analysis of the impact of health shocks on the wealth of elders

We investigate the impact of health shocks on wealth, using all four waves of the Health and Retirement Study, and estimate not only the short-term effect but also the long-term effect of health shocks on wealth of the elderly. We find that new health events lower wealth in elders during the period in which such health shocks occur, but the impact tends to disappear over time. We also find that health shocks result in greater wealth depletion when they occur later in life. Together with existing health problems, the overall impact of health problems on wealth increases over time.

Life with and without heart disease among women and men over 50

This article uses a demographic approach and data from the Health and Retirement Survey, a nationally representative sample of the U.S. population, to investigate sex differences in the length of life lived with heart disease and after a heart attack for persons in the United States age 50 and older. On average, women live longer than men with heart disease. At age 50 women can expect to live 7.9 years and men 6.7 years with heart disease. The average woman experiences heart disease onset three years older and heart attacks 4.4 years older than men.     

Structural Pluralism and Life Expectancy in Less-Developed Countries: The Role of Women's Status

This study replicates a previous finding forthe U.S. counties that showed a strongassociation, net of controls between``structural pluralism' and lower mortality. ``Structural pluralism' refers to a community'scapacity for political competition, and is acore element of ``democracy.' Pluralism hasthis effect because it facilitates theacquisition of appropriate medical facilitiesand because it tends to optimize the biologicalfunctioning of the residents. Working from amajor component of pluralism, minorityparticipation, this hypothesis is tested byshowing that women's status in less developedcountries improves life expectancy net ofcontrols. A path analysis demonstrates thatthe structural dimensions work through healthorganization as an intervening variable, andthe future testing of biological optimizationis outlined. Location in Africa south of theSahara is a partially unexplained controlvariable that has a powerful negative impact. Interpreting women's status as a component ofpluralism explains why it predicts increasedlife expectancy for all citizens, not justwomen. It is a global dimension that affectsall the members of a community.     

The making and unmaking of a “transborder nation”: South Korea during and after the Cold War

The burgeoning literature on transborder membership, largely focused on the thickening relationship between emigration states in the South and the postwar labor migrant populations and their descendants in North America or Western Europe, has not paid due attention to the long-term macroregional transformations that shape transborder national membership politics or to the bureaucratic practices of the state that undergird transborder claims-making. By comparing contentious transborder national membership politics in South Korea during the Cold War and Post-Cold War eras, this article seeks to overcome these limitations. In both periods, the membership status of colonial-era ethnic Korean migrants in Japan and northeast China and their descendants was the focus of contestation. The distinctiveness of the case—involving both a sustained period of colonial rule and a period of belated and divided nation-state building interwoven with the Cold War—highlights the crucial importance of three factors: (1) the dynamically evolving macro-regional context, which has shaped transborder national membership politics in the region in distinctive ways; (2) the essentially political, performative, and constitutive nature of transborder nation-building; and (3) the role of state registration and documentation practices in shaping the contours of transborder national membership politics in the long run. By incorporating Korea—and East Asia more broadly—into the comparative study of transborder nation-building, this article also lays the groundwork for future cross-regional comparative historical studies.

Family Responsibilities,Productivity, and Earnings: A Study of Gender Differences Among Canadian Lawyers

This study examines whether men and women invest in different determinants of productivity and whether these investments affect productivity and salary in different ways. Hypotheses are tested from human and social capital theories that include more direct measures for family responsibilities and family-friendly firm arguments. Data from 670 law firm lawyers were used given they report a standardized measure of productivity in billable hours. Despite men investing more in their careers and women investing more in their families, both report similar productivity and their productivity is affected similarly by these factors. In addition, equally productive men and women are paid the same. The findings further our understanding of productivity and salary and the relevance of family responsibilities and family-friendly firms.
