Blacks report lower marital quality and face a higher risk of marital dissolution than Whites, but little is known about how Hispanics compare to these two groups. We examine five dimensions of marital quality as well as marital dissolution for Blacks, Whites, and Mexican Americans using data from the National Survey of Families and Households (N=6,231). Mexican Americans and Whites have simila...

This research devises a novel concept, service mining, which is derived from the concept of service science and traditional service management. Service mining is defined as a process to discover patterns from services. The goal of service mining is to detect something new from the service pool. Service mining proves the enfolded processes cover two major disciplines and extend to minor sub-disc...

We consider polling systems with general service times and switch-over times, gated service at all queues and with general renewal arrival processes. We derive closed-form expressions for the expected delay in heavy-traffic (HT). So far, rigorous proofs of HT limits have only been obtained for Poisson-type arrival processes, whereas for renewal arrivals HT limits are based on conjectures [5, 6,...

The analytical framework proposed by Davis and Blake (1956) divides the process of reproduction into three elements: (i) exposure to the risk of pregnancy, (ii) the ability to conceive and (iii) successful gestation. This paper is concerned with the first element. Data from the 1973 National Demographic Survey of Tanzania (NDS) are used to investigate the role of marriage behavior in determinin...
