A Comparison of Attitudes About Cremation Among Black and White Middle-Aged and Older Adults

Social workers must be instrumental in educating elders and their families to make informed decisions about death and dying. As part of a larger qualitative study, we explored attitudes about cremation of 25 older and 25 middle-aged adults, evenly split between Black and White respondents. Major themes emerged about disposition of the body after death. Costs and land conservation influenced support for cremation; reasons against cremation include religious beliefs, lack of closure, and sense of place. Additionally, some respondents were against cremation primarily because of lack of exposure, as it was not their family tradition, suggesting a role for education.     

The Relation Between Actual and Intrinsic Growth Rates

This paper demonstrates that, to a close approximation, the intrinsic growth rate of a population is equal to the mean of age-specific growth rates below age T, the mean length of a generation. This mean is normally close to the growth rate of the entire population block below age T. Therefore, when a disparity exists between the intrinsic growth rate and the actual growth rate of a population (whether or not net migration is included in both rates), it must be attributable to an unusual growth rate of the population block above age T. One implication is that the ‘momentum of population growth’ is entirely confined to the age span above T, approximately age 28 in developing countries to-day.     

Images of a Loving God and Sense of Meaning in Life

Although prior studies have documented a positive association between religiosity and sense of meaning in life, the role of specific religious beliefs is currently unclear. Past research on images of God suggests that loving images of God will positively correlate with a sense of meaning and purpose. Mechanisms for this hypothesized relationship are drawn from prior work on attachment theory, religious coping, and symbolic interaction. We suggest that these mechanisms are complementary and that secure attachment styles, reliable coping strategies, and positive self-images work in tandem to facilitate a sense of meaning and purpose. Using a random, national sample from the second wave of the Baylor Religion Survey, we perform multivariate regression analysis that controls for key religious and demographic effects. In our full model, results indicate that the dependent variable is positively associated with student status, religious non-affiliation, congregational friendship networks, and frequency of prayer. Most important from the perspective of the present study, the connection between loving images of God and a sense of meaning and purpose is consistent and robust.     

Anticipating Likely Consequences of Lottery‐Based Affirmative Action*

Objectives. To better understand the consequences of whole or partial reliance on test scores as a screening mechanism for college or university admissions or for job placement or promotion. Methods. We introduce a simple hurdles/threshold model to study one particular mechanism that has been recently proposed to generate a “compromise” between race‐normed or gender‐normed standards for acceptance, on the one hand, and the decision to select those with the highest score regardless of race or gender, on the other—a method we call lottery‐based rules with minimum thresholds of acceptance. Results. We show the factors that determine how close acceptance rates for the disadvantaged group under lottery‐based methods will be to the acceptance rates under either race‐normal or pretest‐score‐based mechanisms. Conclusions. We argue that the likely consequences of using this method are not nearly as attractive as they might first appear to reformers.     

The essential ranking of decision rules in small panels of experts

For small panels of experts (e.g., boards of managers, courts, specialized committees), n 5, this paper provides an algorithm for ranking the seven efficient and commonly used weighted majority rules by their respective performance. These rules are terned efficient since they constitute the set of potentially optimal decision rules in uncertain, symmetric, pairwise choice situations. The main contribution of this study is the discovery of an essential ordering of six of these rules which entails that the set of possible ranking of the seven rules is almost single peaked.The essential ordering significantly reduces the number of possible rankings of the rules, and thus, simplifies the development of the ranking algorithm. The essential ordering has important applications when the available information on the experts' decisional skills is incomplete.

E- and R-optimality of block designs for treatment-control comparisons

Abstract

We study optimal block designs for comparing a set of test treatments with a control treatment. We provide the class of all E-optimal approximate block designs, which is characterized by simple linear constraints. Based on this characterization, we obtain a class of E-optimal exact designs for unequal block sizes. In the studied model, we provide a statistical interpretation for wide classes of E-optimal designs. Moreover, we show that all approximate A-optimal designs and a large class of A-optimal exact designs for treatment-control comparisons are also R-optimal. This reinforces the observation that A-optimal designs perform well even for rectangular confidence regions.
