Population structure and evolution of non-O1/non-O139 Vibrio cholerae by multilocus sequence typing.

Pathogenic non-O1/non-O139 Vibrio cholerae strains can cause sporadic outbreaks of cholera worldwide. In this study, multilocus sequence typing (MLST) of seven housekeeping genes was applied to 55 non-O1/non-O139 isolates from clinical and environmental sources. Data from five published O1 isolates and 17 genomes were also included, giving a total of 77 isolates available for analysis.

Conjugated copolymers containing low bandgap rhenium(i) complexes.

Conjugated copolymers with novel low bandgap rhenium(I) complexes on the polymer main-chain are reported. The low bandgap metal-containing polymers were synthesized by Suzuki cross-coupling polycondensation or Stille coupling polymerization. The metal free copolymers are conjugatively-linked with functionalized intramolecular charge transfer units, which exhibited prominent absorption band in the UV-vis region.

Multilevel factor analysis and structural equation modeling of daily diary coping data: Modeling trait and state variation.

The current study used multilevel modeling of daily diary data to model within-person (state) and between-person (trait) components of coping variables. This application included the introduction of multilevel factor analysis (MFA) and a comparison of the predictive ability of these trait/state factors. Daily diary data was collected on a large (n = 366) multiethnic sample over the course of five days.

Daily stress and alcohol consumption: modeling between-person and within-person ethnic variation in coping behavior.

Objective: Using a daily diary approach, the current study evaluated the relationship between coping and alcohol consumption using a large, multiethnic sample. The primary goals of this study were to (a) identify coping strategies that are either protective or risk factors for alcohol consumption and (b) model between-ethnic and within-ethnic group variation for these relations.

Method: College students (N = 365, 69.
