Romantic relationships that cross racial lines have grown since anti-miscegenation laws were deemed unconstitutional. In The Age of Independence, Rosenfeld argued that parental influence over children’s mate selection processes had waned. Rosenfeld, however, was not able to test this supposition directly because of his reliance on cross-sectional census data. Using Waves I and III of Add Health for a cohort of individuals from 1994 to 2002, we examine whether parents matter in shaping their offspring’s romantic attachments, by exploring whether adolescent reports of maternal closeness and parental control are associated with youth’s likelihood of being in an interracial relationship in emerging adulthood. We find that parental factors do influence emerging adults’ romantic relationships; these associations vary by race, ethnicity, and gender. Among white men, maternal closeness in adolescence reduces the likelihood of being in an interracial relationship in emerging adulthood. Parental control elevates the odds of being in an interracial relationship among black and Hispanic women. We also find that parental decisions on where families live shape offspring’s choices, as relative exogamous group size in adolescence is associated with interracial union formation in later life. Our findings suggest that parental influence remains salient in the partner choices made by emerging adults.
A major key to rejuvenating mature oil and gas fields for improved recovery is the ability to characterize the reservoir between existing wells: currently practised methods for surveying inter-well properties are generally costly. A recent project has combined three technologies which utilize readily available fluid production histories to produce a process for identifying inter-well reservoir communications in producing oil or gas fields. Fluctuations in the well production and injection rate histories are analyzed in the context of coupled geomechanical-flow processes involving activated faults and fractures through (i) the Statistical Reservoir Model (SRM), (ii) conventional correlation analysis and a new technique for extracting rate diffusivity tensors, and (iii) coupled geomechechanical-flow modelling. These technologies have been applied to five oilfields located in the North Sea from the North Viking graben to the Central graben with the key results that (i) the general long-range nature of rate correlations is consistent with some dependence on hydro-mechanical changes near a critical point, and (ii) the patterns of orientational distributions of rate correlations from all five fields are consistent with induced shearing on faults or fractures as an inherent mechanism of reservoir communication. Identification of major reservoir pathways is of substantial advantage to efficiency in reservoir management, leading to benefit for practical issues of well placements and configurations, injectivities, productivities, sweep efficiencies, short-term and longer-term forecasting. In particular the techniques can be used in a time-lapse fashion in order to monitor changes in reservoir behaviour and provide real-time updating of reservoir models. Together, these techniques can directly assist rejuvenation of mature fields; additionally, albeit tentatively, the improved understanding of fundamental reservoir mechanisms can lead to better planning of ‘green’ fields.
This study examined the prevalence of nonresident social fathering among African American youth from single-mother families and their reports of subjective closeness, frequency of contact, and financial support from social fathers during young adulthood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
