"Chain pooling" model selection for two-level fixed effects factorial experiments

As many as three iterated statistical model deletion procedures are considered for an experiment.Population model coeff cients were chosen to simulate a saturated 2⁴experiment having an unfavorable distribution of parameter values.Using random number studies, three model selection strategies were developed, namely, (1) a strategy to be used in anticipation of large coefficients of variation (neighborhood of 65 percent), (2) strategy to be used in anticipation of small coefficients of variation (4 percent or less), and (3) a security regret strategy to be used in the absence of such prior knowledge     

An analysis of indirect mortality estimation

In this paper the robustness of Brass's child-survivorship indirect mortality estimation technique is investigated. An analytical method is developed for studying the error or bias caused in indirect mortality estimates by poor data, badly chosen model functions, and specific demographic assumptions that are often violated in practice. The resulting analytical expressions give insight into the rationale of indirect methods, the conditions under which they are robust, and the magnitude of errors that occur when specific assumptions are violated.     

The declining significance of race among American men during The latter half of the twentieth century

The extent to which racial minority groups face discrimination in the labor market is the subject of considerable debate. Using William J. Wilson's thesis of the declining significance of race as our theoretical context, we provide further empirical evidence about labor market discrimination by investigating wages among African American, American Indian, Chinese American, Hispanic white, Japanese American, and non-Hispanic white men. We find, during the period before the civil rights movement, that a substantively significant wage disadvantage is evident for these minority groups with controls for observed labor force characteristics. In recent data, these net disadvantages are reduced substantially for each of these groups except Hispanics. With the exception of Hispanics, the results support Wilson's thesis.

Mother and Grandmother Parenting in Low‐Income Three‐Generation Rural Households

This study draws data from the Family Life Project to examine parenting behaviors observed for 105 mothers and grandmothers raising an infant in rural low‐income multigenerational households. Multilevel models are used to examine the relationships between maternal age and psychological distress and parenting of the infant by both generations. The findings indicate that young maternal age is a risk factor for less sensitive parenting in the presence of other risks, including psychological distress. Further, young maternal age is associated with negative parenting behaviors by grandmothers only. Grandmothers and mothers displayed similar levels of negative intrusive parenting, but different factors were linked to the observed parenting of each generation. These findings contribute to understanding the benefits and risks of three‐generation households.     

Dual-earner couples and the decision to work less: A conceptual model

This paper examines the factors that affect the decision made by dual-earner couples concerning the possibility of one (or both) partners working a reduced-hours schedule. We rely on a comprehensive review of the literature on part-time work among dual-earner couples and on the factors that affect the decisions couples make about their work hours as well as preliminary findings from our ongoing study to consider two key questions: (1) What factors do dual-earner couples take into account when they consider whether one or both might work a reduced-hours schedule? (2) If the couple decides that one partner will work a reduced-hours schedule, how do they decide which partner reduces the hours of employment? Most previous research has focused on the centrality of gender in the decisions that couples make concerning the hours that they work. However, our review of the literature and the preliminary findings of our current research suggest that there are other factors that affect (directly or indirectly) the couples' decisions related to part-time options. Based on this review we present a new decision-making model for two-earner couples that will have implications for future research and policy initiatives. This paper is particularly timely for several reasons: the number of dual-earner couples continues to increase; there is some indication that more employees would choose to reduce their work hours if that were a viable option; and recently, managers and professional workers have become more vocal about their interest in part-time career options.
