A Model for the Evolution of Marsh Shorelines

Abstract: The evolution of a fringing salt marsh is influenced by the interaction of many factors, including relative sea-level rise, marsh aggradation, nearshore sedimentation, wave climate, and tidal range. Rising relative sea levels generally cause the marsh/upland border to transgress the uplands, thereby potentially increasing the areal extent of a marsh. In contrast, the marsh shoreline may either retreat or prograde in response to the interaction between marsh and lagoonal processes. Consequently, the direction and rate of marsh shoreline movement are critical factors in governing the areal extent of a marsh. Therefore, based on the geomorphic history of a fringing salt marsh in Rehoboth Bay, Delaware, a model for the response of a marsh shoreline is presented. Depending upon the relative rates of marsh and lagoonal processes, a marsh shoreline can either (1) retreat by erosion, (2) prograde, or (3) drown in response to local relative sea-level rise. Specifically, if the rate of marsh aggradation is equal to or greater than the rate of relative sea-level rise (RSLR), then the marsh shoreline either progrades or erodes if the nearshore sedimentation rate is greater than or less than the rate of RSLR, respectively. If the marsh aggradation rate is less than the rate of RSLR, then the marsh drowns.

The Effects of Child Health on Marital Status and Family Structure

Abstract: The purpose of this paper is to provide evidence on the effect of child health on marital stability and family structure in an economic framework. We use the 1988 National Health Interview Survey's Child Health Supplement, with a sample of about 9,000 families, to test whether having an unhealthy child decreases the mother's chance of being married and whether it increases her chance of living in an extended family. Using two different measures of child health, we find that having an unhealthy child decreases the mother's likelihood of being married. Our results imply that children in poor health are more likely to face obstacles beyond their illness because they also are more likely to suffer the consequences of poverty and the poor schooling outcomes that result from being raised in a female-headed household. The only mitigating factor is that unhealthy white children are more likely than their healthy counterparts to be living in an extended family.

Operations on polyhedral products and a new topological construction of infinite families of toric manifolds

Abstract: A combinatorial construction is used to analyze the properties of polyhedral products and generalized moment-angle complexes with respect to certain operations on CW pairs including exponentiation. This allows for the construction of infinite families of toric manifolds, associated to a given one, in a way which simplifies the combinatorial input and consequently, the presentation of the cohomology rings. The new input is the interaction of a purely combinatorial construction with natural associated geometric constructions related to polyhedral products and toric manifolds. Applications of the methods and results developed here have appeared in literature.

An Exploratory Investigation of the Factor Structure of the Reynolds Intellectual Assessment Scales (RIAS)

Abstract: This study investigated the factor structure of the Reynolds Intellectual a ssessment Scales (RI a S) using rigorous exploratory factor analytic and factor extraction procedures. The results of this study indicate that the RI a S is a single factor test. Despite these results, higher order factor analysis using the Schmid–Leiman procedure indicates that all subtests are aligned with their theoretically consistent factors. a ll analyses in this study, including the minimum average partial test, parallel analysis, the Schmid–Leiman procedure, as well as principal factors with orthogonal and oblique rotation, support interpretation at the composite intelligence index level and suggest caution when moving to interpretation at the verbal and nonverbal index levels. The memory subtests should continue to be separated from the main IQ battery because of poor g-loadings and contribution to cross loadings of the intelligence subtests. Interpretation at the subtest level should be eschewed.
