The equations which govern the motion of a rigid satellite in
an inverse-square force field exhibit a weak coupling between the
translation of, and the rotation about the center of mass. The effects
of this translational-rotational coupling on the equilibrium positions
in a circular orbit, and their stabilities are examined....
Academic achievement of adolescent children is directly associated with their success in adulthood. Little is known, however, regarding how adolescents in immigrant families academically grow over time and what factors influence the trajectories. Drawing on the National Educational Longitudinal Survey 1988 (NELS: 88), this study aimed to: 1) identify the...
Milkfish has been farmed in Taiwan for over 300 years. Faced with a limited land resource, the industry is looking at the problem of how to maintain a sustainable and efficient production. This study specified a stochastic production frontier function to estimate potential milkfish farm output and efficiency by using...
The literature on religiousness, spirituality (R/S), and health has increased dramatically in
the past decade, but suffers from a lack of integrative theoretical models and well-defined
constructs. Drawing on self-regulation theory, we hypothesized that the effects of religiousness
(e.g., affiliation, service attendance) on health affects behavioral self-regulation of health habits;...
We examined whether longitudinal patterns of hassles and uplifts trajectories predicted mortality, using a sample of 1315 men from the VA Normative Aging Study (mean age = 65.31, SD = 7.6). In prior work, we identified different trajectory classes of hassles and uplifts exposure and intensity scores over a period...

We examined whether longitudinal patterns of hassles and uplifts trajectories predicted mortality, using a sample of 1315 men from the VA Normative Aging Study (mean age = 65.31, SD = 7.6). In prior work, we identified different trajectory classes of hassles and uplifts exposure and intensity scores over a period...
We investigated whether hassles mediated the effect of life events on mortality in a sample of 1293 men (M[subscript age] = 65.58, SD = 7.01), participants in the VA Normative Aging Study. We utilized measures of stressful life events
(SLE) and hassles from 1989 to 2004, and men were followed...
To examine emotion regulation in later life, we contrasted the modified hedonic treadmill theory with developmental theories, using hassles and uplifts to assess emotion regulation in context. The sample was 1,315 men from the VA Normative Aging Study aged 53 to 85 years, who completed 3,894 observations between 1989 and...
Nitrogen isotopes are an important tool for evaluating past biogeochemical cycling from the paleoceanographic record. However, bulk sedimentary nitrogen isotope ratios, which can be determined routinely and at minimal cost, may be altered during burial and early sedimentary diagenesis, particularly outside of continental margin settings. The causes and detailed mechanisms...
