The Cox Proportional Hazards Model with a Partly Linear Relative Risk Function

The conventional Cox proportional hazards regression model contains a loglinear relative risk function, linking the covariate information to the hazard ratio with a finite number of parameters. A generalization, termed the partly linear Cox model, allows for both finite dimensional parameters and an infinite dimensional parameter in the relative risk function, providing a more robust specification of the relative risk function. In this work, a likelihood based inference procedure is developed for the finite dimensional parameters of the partly linear Cox model. To alleviate the problems associated with a likelihood approach in the presence of an infinite dimensional parameter, the relative risk is reparameterized such that the finite dimensional parameters of interest are orthogonal to the infinite dimensional parameter. Inference on the finite dimensional parameters is accomplished through maximization of the profile partial likelihood, profiling out the infinite dimensional nuisance parameter using a kernel function. The asymptotic distribution theory for the maximum profile partial likelihood estimate is established. It is determined that this estimate is asymptotically efficient; the orthogonal reparameterization enables employment of profile likelihood inference procedures without adjustment for estimation of the nuisance parameter. An example from a retrospective analysis in cancer demonstrates the methodology.     

Migration of Retirement‐Age Blacks to Nonmetropolitan Areas in the 1990s

Older blacks migrated to nonmetropolitan (nonmetro) communities in the 1990s to a degree not true of the past. Some of the nonmetro counties that attracted them are well‐known retirement areas also favored by other retirees, mostly whites. Two‐thirds of black retirement counties, however, are areas in the Old South that are not attracting other retirees at a substantial rate, if at all. Although the data indicate significant rates of retirement‐age blacks migrating to 85 nonmetro counties, most migration by older blacks is to metro destinations.     

Evidence for the use of an algorithm in resolving inconsistent and missing Indigenous status in administrative data collections

Measures of the gap in living standards, life expectancy, education, health and employment between Indigenous and non‐Indigenous Australians are primarily derived from administrative data sources. However, Indigenous identification in these data sources is affected by administrative practices, missing data, inconsistency, and error. As these factors have changed over time, assessing whether the gap between Indigenous and non‐Indigenous Australians has changed over time, based on data unadjusted for these sources of error can potentially lead to misguided conclusions. Combining administrative data on the same individuals collected from different sources provides a method by which a more consistent derived Indigenous status can be applied across all records for an individual within a linked data environment. We used the Western Australian Data Linkage system to produce derived Indigenous statuses for individuals using a range of algorithms. We found that these algorithms reduced the amount of missing data and improved within‐individual consistency. Based on these findings, we recommend our Multi‐Stage Median algorithm be used as the standard indicator of Indigenous status for any reporting based on administrative datasets when multiple datasets are available for linkage, and that algorithmic approaches also be considered for improving the quality of other demographic variables from administrative data sources.     

Population Density and Fertility in 22 Indian Villages

Do agriculturists in the Third World sometimes adjust to increasing population density by having fewer children? Over-time data (1961–1972) for 22 farm villages in India point to such a possibility. Cross-sectionally, villages with higher density tend to have lower fertility, even with controls for village caste composition, prior fertility, female literacy, and agricultural production. Similarly, the regression coefficient for village density is negative when the cross-sections are “pooled.” Population density apparently has an inhibiting effect on fertility in these villages.     

Residential preferences and population redistribution: 1972–1988

In seeking to explain recent trends in population distribution, there has been increased interest in residential preferences. This study is a comparison of preferences based on 1972 and 1988 national surveys, years that bracket a period of considerable change in distribution patterns. Over time there has been a small shift in preference toward cities less than 500,000 in size, primarily by those already living there. Rural settings, especially near cities, continue to be very attractive. At both times studied, more than half of those preferring a smaller or more remote place would retain this preference even if it meant 10% less income. Nevertheless, the proportion preferring to live more than 30 miles from a large city was unchanged and approximately equal to the proportion already living there at both times, indicating that a discrepancy between where people live and where they want to live is not an important basis for the upturn in nonmetropolitan growth away from large cities in the 1970s or the downturn in the 1980s.     

Temporal and spatial variation in age-specific net migration in the United States

As fertility differences in the United States diminish, population redistribution trends are increasingly dependent on migration. This research used newly developed county-level age-specific net migration estimates for the 1990s, supplemented with longitudinal age-specific migration data spanning the prior 40 years, to ascertain whether there are clear longitudinal trends in age-specific net migration and to determine if there is spatial clustering in the migration patterns. The analysis confirmed the continuation into the 1990s of distinct net migration "signature patterns" for most types of counties, although there was temporal variation in the overall volume of migration across the five decades. A spatial autocorrelation analysis revealed large, geographically contiguous regions of net in-migration (in particular, Florida and the Southwest) and geographically contiguous regions of net out-migration (the Great Plains, in particular) that persisted over time. Yet the patterns of spatial concentration and fragmentation over time in these migration data demonstrate the relevance of this "neighborhood" approach to understanding spatiotemporal change in migration.     

Dialing for Dollars: Opportunities,Justifications, and Telemarketing Fraud

Opportunities for deviant economic exploitation grew significantly in the second half of the twentieth century. Drawing from interviews with forty-seven fraudulent telemarketers, this article describes the backgrounds and pursuits of one type of deviant actor that has stepped forward to exploit these opportunities. The men and women interviewed for this research were reared in middle-class, disproportionately managerial and entrepreneurial families. Their class and family backgrounds provided them with high, but ill-defined, expectations for material success. Their preparation for successful conventional careers was unremarkable. As a result, they were predisposed to economic activities that required few credentials but provided a high income. Once involved in and aware of the deviant nature of their endeavors, continuation in fraud was facilitated by the income it produced and the lifestyle it permitted, by self-definitions enhanced by their manipulative abilities, and by acquisition and use of a vocabulary of motive that deflected blame. An augmented version of sociological strain theory provides an analytic vantage point from which to examine the backgrounds, aspirations, and perspectives of those involved in fraudulent telemarketing.
