Our aim in this study was to probe into the factors of team members' team commitment in order to determine if members' teamwork behaviors significantly influence their trust, and if the members' perception of team support influences their attitude or behavior within a team. A total of 548 questionnaires were distributed to teams participating in competitions, and 206 valid samples were collected (rate of return = 38%). The results of structural equation modeling showed that teamwork behaviors, trust, and perceived team support significantly influenced team commitment, teamwork behaviors significantly influenced trust among the members, and perceived team support significantly influenced teamwork behaviors, trust, and team commitment.

A new assay was developed for the determination of five quinolone antibiotic residues in foods, loxacin, enrofloxacin, ciprofloxacin, lomefloxacin, and norfloxacin, by micellar electrokinetic capillary chromatography with indirect laser-induced fluorescence, in which cadmium telluride quantum dots were used as a fluorescent background substance. Some factors that affected the peak height and the resolution were examined. The optimized running buffer was composed of 20 mM SDS, 7.2 mg/L quantum dots, and 10 mM borate at pH 8.8. The separation voltage was 20 kV. Under these conditions, five quinolone antibiotic residues were separated successfully within 8 min. The detection limits ranged from 0.003 to 0.008 mg/kg; the linear dynamic ranges were all 0.01 ∼ 10 mg/kg; and the average recoveries of the spiked samples were 81.4 ∼ 94.6 %. The assay can meet the requirement of maximum residue limits to these five quinolone antibiotics in the regulations of the European Union and Japan and has been applied for determining their residues in animal-derived food.
