PURPOSE The purpose of this study was to describe factors that facilitate or hinder diabetes self-management and elicit participants' preferences and recommendations about the essential components of a culturally competent diabetes self-management program. METHODS Latino patients with type 2 diabetes and their family caregivers were interviewed in focus(More)
To ascertain the distribution of whole-arm translocations (WATs) and their consequential imbalances in hematologic malignancies, we analyzed the imbalances related to chromosomes involved in clonal, acquired WATs in 140 consecutive tumors with WATs and near-diploid karyotypes. Tumors for analysis were obtained from a survey of the cytogenetic database in(More)
PURPOSE To explore the political and economic dimensions of diabetes self-management for Mexican American adults. DESIGN Critical ethnographic analysis of focus group data from caregivers and adults with diabetes. FINDINGS Three themes were identified: diabetes self-management is tied to other mental and bodily states, family and neighborhood(More)
A deterministic system of interacting agents is considered as a model for economic dynamics. The dynamics of the system is described by a coupled map lattice with near neighbor interactions. The evolution of each agent results from the competition between two factors: the agent's own tendency to grow and the environmental influence that moderates this(More)
In 1940, the tidal Delaware River was "one of the most grossly polluted areas in the United States." During the 1950s, water quality was so poor along the river at Philadelphia that zero oxygen levels prevented migration of American shad leading to near extirpation of the species. Since then, water quality in the Delaware Basin has improved with(More)
The searching for the stable patterns in the evolution of cellular automata is implemented using stochastic synchronization between the present structures of the system and its precedent configurations. For most of the known evolution rules with complex behavior a dynamic competition among all the possible stable patterns is established and no stationary(More)
A transition from asymmetric to symmetric patterns in time-dependent extended systems is described. It is found that one dimensional cellular automata, started from fully random initial conditions, can be forced to evolve into complex symmetrical patterns by stochastically coupling a proportion p of pairs of sites located at equal distance from the center(More)
Many plants, including grasses and some important human food sources, accumulate, and precipitate silica in their cells to form opaline phytoliths. These phytoliths contain small amounts of organic matter (OM) that are trapped during the process of silicification. Previous work has suggested that plant silica is associated with compounds such as proteins,(More)
