Researchers have extensively documented a strong and consistent education gradient for mortality, with more highly educated individuals living longer than those with less education. This study contributes to our understanding of the education–mortality relationship by determining the effects of years of education and degree attainment on mortality, and by including non-degree certification, an important but understudied dimension of educational attainment. We use data from the mortality-linked restricted-use files of the Panel Study of Income Dynamics (PSID) sample (N = 9821) and Cox proportional hazards models to estimate mortality risk among U.S. adults. Results indicate that more advanced degrees and additional years of education are associated with reduced mortality risk in separate models, but when included simultaneously, only degrees remain influential. Among individuals who have earned a high school diploma only, additional years of schooling (beyond 12) and vocational school certification (or similar accreditation) are both independently associated with reduced risks of death. Degrees appear to be most important for increasing longevity; the findings also suggest that any educational experience can be beneficial. Future research in health and mortality should consider including educational measures beyond a single variable for educational attainment. 相似文献

Objective. We explore, first, whether wealth relates to mortality risk independent of income and education, and second, whether wealth closes the black‐white gap in U.S. adult mortality while controlling for other socioeconomic and sociodemographic factors. Methods. We employ the Cox proportional hazards models on data from the 1992 wave of the Health and Retirement Study linked to deaths through 1998, to analyze pre‐retirement adult mortality in the United States. Results. The findings suggest that broader measures of SES, including wealth, are significant for understanding adult mortality. Further, vastly lower asset holdings among blacks, compared to whites, not only affects their financial well‐being but also their survival prospects. Conclusions. Research and social policies that aim to understand and close health disparities in the United States may be poorly conceived if they ignore the impact of wealth on premature adult mortality. 相似文献

Adolescents' antisocial behavior and negative conflict management styles are each associated with adverse romantic relationship outcomes, yet little research exists on their associations. We investigated whether adolescents' antisocial behavior was associated with conflict management styles, and whether it predicted breakup 3 months later. In total, 91 adolescent couples (Mage = 16.43, SD = 0.99; 41.2% Hispanic/Latinx) participated in videotaped conflict discussions coded for negotiation, coercion, and avoidance. Actor–partner interdependence models suggest adolescents' antisocial behavior is associated with decreased use of negotiation (couple pattern) and increased use of coercion (actor pattern). No significant associations were found for avoidance. Neither antisocial behavior nor conflict management styles predicted breakup. Findings are discussed in light of the unique developmental importance of adolescents' romantic relationships. 相似文献

Inventory management has undergone significant philosophical changes in recent decades such as the advent of the zero inventory concept. However, as attractive as the concept of minimal inventories may be, it is often unrealistic in application. Attention to basic features of inventory control systems such as order quantities, base stock levels, and reorder points remain crucial to ensure customer service at minimal cost. A nonlinear optimization model for determining base stock levels in a multi-echelon inventory network is presented. Lagrangian relaxation results in (1) newsboy-style relations that provide the optimal solutions, and (2) instantaneous shadow prices for the budget constraint. Sensitivity analysis of this model will facilitate making decisions concerning the desired investment in inventory for the entire system. This model may be solved on standard nonlinear programming software and is generalizable to problems in both production and distribution settings. 相似文献
